3 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
4 New function yaz_enable_panic_backtrace which enables backtrace
5 handler for current process. The handler will call backtrace always,
6 then gdb to provide as much detail as possible.
10 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
11 and ZOOM record render will inspect leader 9 and switch to UTF-8
12 (Unicode) if that holds 'a'. This changes behavior, but is considered
13 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
15 Fix cs_put may reconnect if send fails. YAZ-798
19 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
23 Extended comstack with outgoing IP YAZ-795.
24 For cs_create_host + cs_create_host_proxy the vhost may be followed
25 by a outgoing host/IP. Separator is blank.
29 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
30 linker error with yazpp on Windows.
34 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
36 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
38 0 ptr reference in handling Solr response with error YAZ-791
40 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
42 Fix documentation about --installa option YAZ-788
46 daemon: properly report when receiving SIGUSR2 from child YAZ-785
50 xmalloc: throw assert for clearly invalid calls to malloc and
51 improve diagnostics YAZ-783 YAZ-784
55 Stop building debs for Ubuntu raring, quantal, oneiric.
57 CCL YAZ-781: for multiple use attributes in a specification the
58 generated RPN will perform @or on each term.
59 For spec: term u=31 u=1016
60 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
62 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
64 CCL YAZ-779: combo qualifier should allow for forward references
66 Fix buildconf.sh, automake too old on centos5 YAZ-778
67 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
68 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
69 accepts it without a warning.
73 GFS: client_query_charset conversion YAZ-777
74 This is a feature for Z39.50 clients that sends queries that are not
75 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
76 encoding given to UTF-8.
78 Echoed SRU arguments support YAZ-776
79 This is achieved with new function yaz_srw_get_pdu_e.
81 ZOOM: expire times set for redis/memcached YAZ-772
82 For both redis and memcached option --expire=seconds sets expire
83 time for a result-set/search. Default time is 600 seconds (10 minutes).
87 No [rest of output is omitted] limit for yaz_log YAZ-774
89 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
91 For ICU testing, pass -o to yaz-icu. This will test the
92 icu_iter_get_org_info function.
94 Fix null ptr reference for freeReplyObject YAZ-773
98 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
100 RPM: do not build with libmemcached support. The libmemcached library
101 on CentOS 5/6 does not work reliably for us (redis to the rescue).
103 configure: only allow libmemcached version 0.40 or later. That's the version
104 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
105 that's not an option, consider redis.
109 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
111 Fix zoom+memcached: present request out of range YAZ-767
115 CCL: add new qualifier r=omiteq which will omit relation=equals
116 for ordered relations. This should be used in combination with either
119 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
121 Solr: simplify yaz_solr_decode_response
123 Solr: use different local var for string manipulation
125 Solr: Get rid of hardcoded limit of extra_args
127 Solr: encode lucene query type YAZ-736
128 Make sure the queries are treated as traditional "lucene", because that's
131 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
135 Build packages for Ubuntu Trusty Tahr 14.04 LTS
137 wrbuf_cstr: fix off by one error.
139 wrbuf_buf: make it always return non-NULL
140 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
144 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
146 zoomsh: offer option -a apdulog
147 As we're used to from yaz-client and GFS based servers.
149 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
150 existing setting apdulog takes effect.
152 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
157 Add re-entrant CQL/Solr/RPN query conversion functions.
158 The re-entrant functions are: cql_transform_r,
159 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
160 These have same functionality as cql_transform,
161 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
162 return the additional infomration as WRBUF to make them re-entrant.
164 Remove CQL to Solr conversion and base solr_transform_t on
165 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
166 data structure as cql_transform_t.
168 cql2pqf utility allows RPN to Solr conversion
170 Fix assert in ZOOM when http connect fails YAZ-757
172 --- 5.0.22 2014/04/09
174 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
176 wrbuf_cstr: make it thread safe YAZ-753
178 yaz_log_init_file may take fd=<no> to open log file at the FD given.
180 --- 5.0.21 2014/03/21
182 Offer new utility function zget_AttributeList_use_string.
184 New conversion step, solrmarc, for record conversion module.
186 --- 5.0.20 2014/03/13
188 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
189 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
192 --- 5.0.19 2014/03/10
194 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
195 The standalone ZOOM sort was completely broken since 5.0.13.
197 ZOOM: generate event Connect rather than None for partial connect
198 (in fact getaddrinfo resolving).
200 ZOOM: only supply clientIP for InitRequest. Rather than for all
203 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
205 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
206 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
207 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
209 New "Facets" section in the documentation.
211 --- 5.0.18 2014/02/27
213 Call exsltRegisterAll in yaz_init_globals, so that all applications
214 using YAZ will have EXSLT things enabled.
216 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
218 Update various URLs to the re-organized SRU pages at LoC.
220 --- 5.0.17 2014/02/26
222 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
223 introduced in 5.0.12.
225 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
226 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
227 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
230 --- 5.0.16 2014/02/25
232 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
234 --- 5.0.15 2014/02/24
236 Fix gcrypt not properly initialized YAZ-740.
238 --- 5.0.14 2014/02/19
240 Describe memcached option for ZOOM.
242 ZOOM: throw present request out of range again YAZ-739
243 Was removed in YAZ 5.0.13.
245 --- 5.0.13 2014/02/18
247 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
248 with localtime_r when threads + fork is used (such as Metaproxy).
250 yaz-config: quote some RHS values (that might include blanks)
252 zoomsh: shows SearchResult-1
254 zoomsh: sortby command
256 zoomsh: use proper list of connections and result sets YAZ-725
258 Avoid yaz_log in sigterm handler for GFS YAZ-737
259 Logging is still performed, but outside sig handler.
261 New ZOOM C feature: result-set caching with memcached. Example:
262 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
264 Remove SSL via OpenSSL support YAZ-732
265 Also deprecate two functions from comstack that aren't working with
266 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
268 Revert "Bison: use %name-prefix directive rather than -p option"
270 --- 5.0.12 2014/01/22
272 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
274 SRU GET/Solr base URLs may hold additional ?args YAZ-729
275 ZOOM option extraArgs already does this, though. It seems useful
276 when dealing with Solr targets to limit by filter, eg.
277 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
279 Remove #fragment for HTTP request encoding YAZ-730
281 Doc: Update list of DLLs/LIBs
283 Doc: update href link to Unix utils and Git.
285 --- 5.0.11 2014/01/15
287 ZOOM: fix "lost connection" problem with servers that uses both squid
288 and another proxy behind it that returns Location headers with relative
291 zoomsh: do not use readline for stdin (no tty) YAZ-724
292 Just use fgets in that case. If the user hits Ctrl-D a new-line
295 zoomsh: empty command ignored YAZ-723
296 rather than performing exit of zoomsh.
298 yaz-url utility offers option -v to enable verbose mode.
300 yaz_url uses yaz_check_location and offers verbose mode.
302 Add new function yaz_check_location.
303 This function gets an absolute URI from Location (HTTP redirect).
305 cookie API: introduce yaz_cookies_reset
307 Update cql.y for newer bison YAZ-720
308 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
309 longer supported. Instead one must use %lex-param and %parse-param .
311 --- 5.0.10 2014/01/09
313 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
316 rpn2solr: support truncation left(2), left&right(3) YAZ-718
318 Mention SRU version 2.0 in yaz-client man page.
322 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
327 Make cs_parse_host public.A
329 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
330 introduced in YAZ 5.0.6.
334 Fix buffer corruption for yaz-ztest record fetch.
338 Allow yaz-ztest to return user-defined records (one record per file).
339 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
341 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
342 Use the stream write instead of odr_printf which has a 4K tmp buffer.
344 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
348 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
349 can read and write this format. For record format JSON, yaz-ztest returns
350 MARC-in-JSON records.
352 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
353 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
357 Improve error reporting for ICU chains YAZ-707
358 Report config element+rule when ICU status is "failure".
360 ZOOM: stop fetching if present response has no records YAZ-710
361 Some targets return less records than their hit count would suggest.
362 This prevents ZOOM from continuing to fetch records if any present
363 response has 0 records in the response.
365 Ensure that GFS calls exit if any listener fails YAZ-710
366 Before, if XML config was in use, it would start the default
371 yaz-ztest: -V shows version (like yaz-client -V)
373 New iconv encoding: danmarc YAZ-692
375 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
377 daemon: only wait for immediate child rather than all children. YAZ-704
379 yaz-client: fix setting of SRU record schema. If scheme was unset, it
380 could lead to invalid memory reference.
384 yaz-ztest returns schema for MARCXML test records. SRU require that
385 recordSchema for records.
387 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
388 instead of non-surrogate diagnostic. This is a per-record failure.
390 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
391 may refer to multiple listeners now. Attribute listenref is a comma separated
394 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
395 option is given for GFS, the dirname of filename (for -f) is used
396 as prefix for options such as cql2rpn, ccl2rpn, etc.
398 Content-Type charset fixes YAZ-701 . Do not inspect charset in
399 Content-Type header for SOAP when decoding SRU. The payload (XML)
400 itself tells what encoding it is. In response, never supply encoding
401 in Content-Type. The response payload (XML) tells what it is (with no
402 encoding in XML it's UTF-8).
404 HTTP decoding: allow blanks in URL paths YAZ-700
408 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
409 and facets. Ensure recordData and recordSchema are always present in
410 record element, because they are required.
412 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
415 Simplify in a lot of places using odr_strdupn.
417 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
421 Increase various buffers in GFS's statserv_options_block
422 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
423 This change makes many type-casts redundant, and, thus simplifies code.
425 Remove last bits of WAIS support.
427 Remove member 'size' from Odr_oct.
429 Slim down the public part of 'struct odr'. Most elements are not part
430 of struct Odr_private.
432 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
433 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
434 In particular facets are supported in both client - and server side.
435 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
436 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
437 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
438 both request/response). This is what a search handler in the GFS
439 will see (regardless of whether operating in SRU mode or Z39.50).
441 Changes to the srw.h (SRU/Solr) definitions include:
442 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
443 (char*), which replace union query and query_type (int). This is because
444 SRU 2.0 supports a queryType parameter. This also means that, to carry
445 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
446 x-pquery=PQFstring (extention parameter). The extension parameter
448 - New element, packing, that has information about SRU
449 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
451 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
453 New element, packing, in Z_SRW_explainRequest.
455 New elements in Z_SRW_scanRequest, queryType and scanClause.
456 These replace query_type and scanClase untion. This is similar to what
459 --- 4.2.69 2013/10/01
461 GFS: log when closing down - at least SIGTERM YAZ-684
462 Also change formatting WRT PID logging a bit.
464 Improve display of MARC records with multi-byte subfield IDs YAZ-695
465 In some rare cases subfield identifiers are multi-byte characters.
466 This will try to deterime length of those and split accordingly.
467 This affects display in line mode as MARCXML/MarcXchange. The encoding
468 of ISO2709 is the same.
470 Change inp argument to const for yaz_read_UTF8_char.
472 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
474 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
476 Better check of marc leader info YAZ-691
477 Problem is that some systems generate MARCXML/MarcXchange with
478 funny headers. These will not work if encoded as ISO2709.
479 Some tests produce new output, due to updated warning messages
481 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
483 yaz-client: display MAB records YAZ-689.
484 Thanks for Heiko Jansen for this patch.
486 New utility z_get_HTTP_Response_server which allows both HTTP server name
487 and HTTP server URL to be given in response.
489 Debian: do not depend on obs tcl8.3.
491 Debian: do not depend on obs libicu36-dev.
493 --- 4.2.68 2013/09/23
495 GFS: pass additionalSearchInfo to search memeber search_input if
496 given. Otherwise pass otherInfo. Request for facets and other search
497 related things will be passed there in future versions of YAZ.
499 New ZOOM setting, authenticationMode, which allows authentication
500 paramters to be encoded in the URL rather than via HTTP Basic auth.
503 rpn2solr: fix nested AND/OR handling. YAZ-685
505 Add comparison routines for some Z-types, such as NamePlusRecord,
506 RPNQuery, Query, RecordComposition and OtherInformation.
508 --- 4.2.67 2013/09/19
510 Don't decode MAB as MARC. Just like we don't attempt to decode
511 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
513 CCL: allow quoted terms for date ranges. YAZ-681
515 Introduce ccl_parser_qual_search. This function makes old function
516 ccl_qual_search, from YAZ 2, available again.
518 Add yaz_facet_list_to_wrbuf. YAZ-683
520 --- 4.2.66 2013/09/11
522 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
523 schema was given for search. YAZ-675
525 Add Solr date range searches. YAZ-621
527 --- 4.2.65 2013/08/22
529 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
531 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
533 ISO2709/MARC parse most octet aligned records; not just those that
534 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
535 MARC parse more records instead of just dumping as is. YAZ-670
537 ZOOM: proper caching for variations of record schema. YAZ-671
539 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
541 --- 4.2.63 2013/07/17
545 --- 4.2.62 2013/07/11
547 New utility z_get_HTTP_Response_details - an extended version of
550 New utility yaz_url_get_error which returns error message of last
551 failed yaz_url_exec call.
553 yaz-url and url functions: allow max HTTP redirects to be controlled.
555 New functions yaz_file_glob2, yaz_xml_include_glob.
556 These functions takes a flags parameter, which, for now only controls
557 whether to fail inclusion of a non-existing file (without glob
558 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
560 --- 4.2.61 2013/06/20
562 For MARC XML parsing, allow record without leader. A fake/default leader
563 is inserted and a warning is tagged with the record.
565 ICU: fix leak in in icu_iter_get_org_info.
567 --- 4.2.60 2013/06/14
569 ICU: fix bug in icu_iter_get_org_info (un-init variable).
571 --- 4.2.59 2013/06/11
573 Implement z_HTTP_header_remove.
575 --- 4.2.58 2013/06/11
577 ICU: Disallow 0 ptrs for some ICU string utilities.
579 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
580 returns original tokens (before normalization).
582 CCL: avoid z39.58/regex truncation when not needed. Apply only the
583 conversion of those masks, when absolutely necessary.
585 CCL: configurable masking character - @mask. Default masking character
588 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
589 full response anyway, so a Transfer-Encoding header will obstruct the
592 --- 4.2.57 2013/05/15
594 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
595 picking a socket. Problem is that some systems has IPV6 support, but
596 we can't create sockets for them, so we pick AF_UNSPEC first.
598 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
599 use content_len to determine resulting Content-Length in HTTP response
600 and NOT Content-Length supplied in headers by user.
602 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
603 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
605 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
608 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
609 with big endian and unsigned char (by default).
611 --- 4.2.56 2013/04/26
613 Fix yaz-client connect (crash in 4.2.55).
615 --- 4.2.55 2013/04/26
617 Fix proxy/host problem for ZOOM that could occur if unix sockets
620 New Debian package libyaz4-dbg.
622 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
623 differently in tcpip_close.
625 --- 4.2.54 2013/04/17
627 Windows installer of YAZ includes YAZ4J as a component.
629 CQL: allow "extra terms" again, by default. Thus, the CQL parser
630 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
631 and earlier. CQL parser may operate in strict mode where queries
632 not conforming to the standard BNF are rejected (syntax error).
633 Whether the CQL parser operates in strict mode is controlled with
634 cql_parser_strict . Strict mode enabled with option -S for utilities
635 cql2pqf and cql2xcql .
637 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
639 --- 4.2.53 2013/04/10
641 New charset, MARC-8c, which is like MARC-8 but allows control characters
642 0x01 through 0x1F, except ESC to be passed through verbatim.
644 Fix a problem with duplicate sub field character in MARC output. Problem
645 happened only when output was MARC-8 encoded.
647 --- 4.2.52 2013/04/03
649 yaz-ztest: Use hash for fake hit count. Before, random number was used.
650 This is problematic for unit tests using yaz-ztest. This patch also makes
651 a hash for CQL queries. For RPN, any term with a leading digit will be
652 treated as pseudu hit count (to force any particular hit count by a client).
654 yaz-ztest: return unique MARC dummy records. Beyond record offset
655 24, the author surname is patched with offset to make all records
658 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
659 on system wide default (/proc/sys/net/ipv6/bindv6only).
660 @4 binds to IPV4 only. @6 binds to IPV6 only.
662 Update CQL API documentation a bit
664 CQL: don't accept extra terms for queries. Makes the CQL parser
665 stricly conformant to the standard.
667 --- 4.2.51 2013/02/12
669 GFS: scan handler gets extra_args from request and may return extra
670 response data . That's for SRU only.
672 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
674 --- 4.2.50 2013/01/30
676 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
678 OPACXML: sync spelling of availabilityDate in XML to that of Schema
679 opaxxml.xsd. The schema had the correct spelling of this member always.
680 The ASN.1 was mis-spelled and still is (API change) - we are
681 not changing this. However, the OPAC to XML conversion had yet
684 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
687 New function, z_ext_record_oid_nmem, which is similar to
688 z_ext_record_oid but takes NMEM rather than ODR
690 --- 4.2.49 2013/01/18
692 ICU: New conversion element 'join' which joins tokens into one
693 with a custom character given by rule attribute.
695 --- 4.2.48 2013/01/10
697 New GFS search member: present_number. This is a hint to the
698 search handler how many records are going to be fetched immediately
699 following search. There's no guarantee that it's going to be the case,
700 since it depends on hit count (for Z39.50 piggyback) and whether errors
703 Make a few functions static (private). The functions getbyte_stream,
704 ungetbyte_stream and yaz_gets are now private. They were never declared
707 yaz-marcdump: exit(5) for serious decoding errors
709 ISO2709 decoding: be more picky WRT header
711 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
712 was only used as to indicate that next-result-set-position should be
714 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
715 Based on patch from Ashley Sanders.
717 Make some functions static/private in PQF parsing. Those functions were
718 never declared in a public header and so should not be in use by
719 applications based on YAZ.
721 --- 4.2.47 2012/11/23
723 ZOOM: special options to control APDU logging.
724 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
725 logging of APDUs until "saveAPDU" option is set again. If logging is
726 already enabled the effect is that current APDU buffer is cleared.
727 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
728 logging (default behavior on new connection).
729 The APDUs sent/received can be obtained by using
730 Using ZOOM_connection_option_get(c, "APDU") or
731 ZOOM_connection_option_getl(c, "APDU", &l).
733 GFS: relay implementation_version from backend
734 From 3.0.40 and later, implementation_version from backend was
735 not used in init response at all.
737 --- 4.2.46 2012/11/15
739 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
740 mode at all. Probably never did.
742 Make a new version of ztest.pem that, at least, is not expired.
744 --- 4.2.45 2012/11/13
746 Fix description of CCL directive 'case'.
748 More tight checking of form arguments (yaz_uri_to_array). Makes
749 YAZ better at rejecting big and/or bad POSTs.
751 SRU decoding does not report more than up to 10 invalid arguments.
753 rpn2cql: less quotes in generated terms. Semantics unchanged, but
754 it's prettier this way.
756 --- 4.2.44 2012/10/25
758 New utility yaz_decode_init_diag. Defined in proto.h.
760 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
761 given for unix local socket.
762 The COMSTACK string for doing so is:
765 unix:/myfile:tcp:localhost:9999/mybase
766 unix:/myfile:localhost:9999/mybase
767 unix:/myfile:http://fakehost/mybase
769 debian: Use dpkg-buildflags in build process.
771 --- 4.2.43 2012/10/19
773 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
774 global's SRU service uses a recordPosition scheme starting from zero.
775 First record's position should be one
776 according to the standard.
778 --- 4.2.42 2012/10/18
780 Allow more namespaces for SRU. This is to allow, for example, an
781 incorrect namespace returned from server
782 http://services.igi-global.com/sru .
784 Minor fixes for compilation on Windows.
786 --- 4.2.41 2012/10/11
788 daemon: log total number of bad signals from child on stop so that it
789 is more easy to spot problems with child worker processes.
791 retrieval: empty backend name attribute omits element set
792 from being used in retrieval.
794 --- 4.2.40 2012/10/04
796 Implement Solr sort strategy "solr", similar to sru11 sorting.
797 This will implement the correct parameters on Solr requst to do
800 --- 4.2.39 2012/09/28
802 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
805 MARC: Extra/missing indicator handled for MARCXML.
806 The indicator length is given in header and is the same for the
807 whole record. If attributes ind1, ind2 are missing, then content
808 character defaults to blank. Extra indicator attributes (beyond)
809 indicator length are treated as an error.
811 Reformat: delete trailing whitespace
813 --- 4.2.38 2012/09/17
815 MARC: fix non-ASCII characters for leader. This is to ensure we can
816 generate XML in UTF-8.
818 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
819 in one node with structure word.
821 --- 4.2.37 2012/09/04
823 yaz-json-parse: JSON output may be pretty printed by using option
826 Increase default value of max message for Z39.50 Init for GFS, ZOOM
827 and yaz-client. Old value was 1 MB. New value is 64 MB.
829 --- 4.2.36 2012/08/22
831 yaz-client: don't display bogus records from SRU servers. Some SRU servers
832 return more records than given by *maximumRecords*. Skipping those in
835 record_render: simplify buffer return handling and fix at least one bad
836 memory reference, that broke the test_embed_record sometimes.
838 Allow http://user:pass@host notation for yaz_url_exec.
840 zoomsh: allow shell command to be executed. Via the system(3) call.
842 yaz_poll: Allow num_fds == 0
844 yaz-client: fix bad encoding of "itemorder item". The itemorder
845 item <no> - command forgot to use length of encoded Item Request
846 package. Error present since YAZ 3.
848 yaz-ztest: fix bad usage of session handle. Bug was introduced when
849 result sets were saved (271a9c83).
851 SRU recordPacking: guess record packing in response rather than looking
852 at the recordPacking element which, OF COURSE, changed semantics in SRU
855 Decode SRU 2.0 responses. The official namespace for responses, according
856 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
857 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
858 nature.com's server, however, usee namespace
859 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
860 we are now using a glob-expr to match up the namespace. ZOOM C and
861 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
862 I can not find a single real example showing the "real" namespace in
863 the documentation from OASIS. The namespace for requests is different
864 from responses, but this is not added to YAZ yet, when we don't encode
867 --- 4.2.35 2012/06/26
869 zoom/record_render: add support for Base64 decoding fo MARC records
870 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
871 which will decode base64 + ISO2709 marc-8 encoded material from text node
874 --- 4.2.34 2012/06/07
876 Add missing definitions ZOOM_resultset_get_facet_field_by_index
877 and ZOOM_resultset_facets_names.
879 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
882 Change APDU dump printing to avoid long leading blanks. For levels 16
883 or larger the level is shown and the indentation is truncated but
884 recursed with modula 8. This makes it still reasonable easy to read
885 - even for nested BER dumps.
887 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
888 return 0 (incomplete package) in case where the BER package was
889 considered too nested (return value of -2).
891 dumpber: lines of level 15 are not indented further. Two spaces per
892 indentation; indentation 15 or more is indented to a fixed indentation
893 and augmented with a level=<no> indication.
895 zoomsh: increase max size of command+args
897 GFS: No limit in RPN buf size in CQL to RPN conversion.
899 --- 4.2.33 2012/05/09
901 New function for daemon utility, yaz_daemon_stop .
903 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
905 --- 4.2.32 2012/04/25
907 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
908 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
910 --- 4.2.31 2012/04/23
912 YAZ daemon utility relays SIGUSR1 to child process.
914 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
915 would result in en empty database list - which in turn would result in
916 encoding failure for search.
918 Fix reading beyond string in yaz_sort_spec.
920 --- 4.2.30 2012/04/11
922 Add two new SRU diagnostics:
923 236: Access to specified database denied
924 1015: Init/AC: Maximum number of simultaneous sessions for Userid
926 Document the very useful ZOOM-C option "apdulog".
928 CQL to RPN: term may be passed through verbatim. This is enabled with
929 truncation.cql . The assumption being that the term is already CQL.
931 --- 4.2.29 2012/03/20
933 record_conv: leader spec may be given for marc element.
934 The leader spec is given as attribute leaderspec for element marc.
935 For example to convert a MARC21 record from MARC-8 to UTF-8:
936 <marc inputformat="marc" outputformat="marc"
937 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
939 record_conv: allow user-XSLT params. For example:
940 <xslt stylesheet="MARC21slim2DC.xsl">
941 <param name="myparameter" value="myvalue"/>
942 <param name="otherparameter" value="othervalue"/>
945 record_conv: fix error handling for missing marc charsets.
947 CQL: fix extra terms in wrong order.
949 --- 4.2.28 2012/03/06
951 record_conv: modify new API for conversion types. The conversion types
952 may be passed in new functions yaz_record_conv_configure_t and
953 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
955 Avoid mixed statement/variable declare; fixes compilation with Visual
958 --- 4.2.27 2012/02/28
960 Add non-standard SRU diagnostic: 235: "Database does not exist".
961 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
962 Update SRU to Bib-1 diagnostic maps accordingly.
964 CCL: add two new diagnostics for unsupported masking. The new
965 diagnostics are: "Embedded truncation not supported" and
966 "Single charcacter mask not supported".
968 --- 4.2.26 2012/02/23
970 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
972 --- 4.2.25 2012/01/11
974 Build YAZ for Ubuntu Oneiric.
976 CCL: allow parantheses for proximity operands. For example CCL query
977 (a) % (b) is now allowed.
979 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
980 marked dead, rather then being destroyed. If not, the session memory is
981 being free'd before the search/scan handler is finished. Also destroy
982 'request' memory in request_release rather than in various places,
983 which resulted in leaks from time to time.
985 --- 4.2.24 2011/12/21
987 cql_sortby_to_sortkeys: honor sort prefix.
989 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
990 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
991 The rpn2cql family of functions now always returns quoted CQL terms.
993 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
995 --- 4.2.23 2011/12/15
997 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
998 sequence is treated as one. For example, &&a=b&&&c& is identical to
1001 --- 4.2.22 2011/12/05
1003 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1004 APDUs for a connection to a WRBUF.
1006 --- 4.2.21 2011/11/23
1008 Fix cql_sortby_to_sortkeys. Completely broken before.
1010 Make CCL's @truncation work again.
1012 --- 4.2.20 2011/11/09
1014 New ZOOM connection setting: tproxy. It's like proxy, but does not
1015 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1016 to set resolved address + port for a connection outside ZOOM itself.
1018 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1020 --- 4.2.19 2011/11/07
1022 Fix uninitialized variable in Solr spell support (could cause SEGV
1023 for SRU response decoding).
1025 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1026 back-end's addinfo through into the ZOOM response addinfo.
1028 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1029 they are separated by a colon and a space rather than simply
1032 --- 4.2.18 2011/10/28
1034 Add support for Solr spell-checking/suggestions through ZOOM.
1035 If a Solr target has been configured correctly for spelling-checking
1036 and suggestions, these will now be returned on the ResultSet option
1037 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1039 --- 4.2.17 2011/09/28
1041 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1042 with a flag whether to substitute escape sequences or not.
1044 --- 4.2.16 2011/09/22
1046 Fix nmem_strsplit_escape to substitute escape char properly.
1048 New option for zoomsh -e , which makes it abort on first error and
1049 return process exit code to indicate success/failure.
1051 YAZ options utility supports special option -- which makes all it treat
1052 all following arguments as non-options.
1054 --- 4.2.15 2011/09/16
1056 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1057 searched if absolute filename is given.
1059 Fix conv_xslt() error-reporting when stylesheet is not found.
1060 (The value of fullpath is meaningless in this situation.)
1062 --- 4.2.14 2011/09/07
1064 Fix problem in CQL sort node creation: un-initialized memory.
1066 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1067 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1068 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1071 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1072 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1074 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1075 will make it possible to use both single-character mask (#) and wildcard (?)
1076 in CCL . Throw diagnostic for left truncation because that is not supported
1079 --- 4.2.13 2011/09/01
1081 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1082 cases using escapes (\-sequences) and masking.
1084 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1085 would result in a read one byte beyond string.
1087 rpn2ccl may use Z39.50 masking for terms (t=z).
1089 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1091 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1092 not --cppflags (which seeems like an error in icu-config).
1094 --- 4.2.12 2011/08/27 RPM package only
1096 cql2ccl: fix conversion of terms: operator characters were not
1099 --- 4.2.11 2011/08/25 RPM package only
1101 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1102 CCL parser will map both # and ? to their regular expression
1103 quivalents (. and .*).
1105 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1106 of reserved CQL characters.
1108 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1109 is, so that they are passed through.
1111 --- 4.2.10 2011/08/24
1113 ZOOM SRU mode: more aggressive re-connect.
1115 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1116 made available as a utility function, declared in <yaz/logrpn.h>
1118 rpn2cql_structure() supports proximity nodes (except that the Type-1
1119 proximity node's "exclusion" binary is ignored, as there is no way to
1120 express that in CQL). Fixes bug #4564.
1122 --- 4.2.9 2011/08/18
1124 Fix SEGV that could occur if set command of zoomsh was given without
1125 value (2nd argument).
1127 Fix SEGV that could occur if unsupported transport was given for
1128 COMSTACK - say https (when SSL was unavailable).
1130 Build yaz-url on Windows too.
1132 --- 4.2.8 2011/08/11
1134 New utility to get web content. Header is url.h. A command line tool
1135 yaz-url is part of the distribution and packages.
1137 Fixes for SSL COMSTACK (when gnutls is in use).
1139 New functions yaz_base64{encode,decode}. Header is base64.h.
1141 --- 4.2.7 2011/08/03
1143 ZOOM C includes HTTP response buffer as additional info if it fails
1144 to decode the SRU response.
1146 Make wrbuf_json_puts available.
1148 --- 4.2.6 2011/07/28
1150 zoom: throw diagnostic for invalid value for option "sru". Before a
1151 bad SRU request was sent.
1153 Adding new utility wrbuf_vp_puts.
1155 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1157 --- 4.2.5 2011/07/21
1159 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1160 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1161 redirect was used at the same time.
1163 MARC line mode decoding: be less picky about length given - first
1164 5 digits of header that is.
1166 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1168 Changes to decoding of SRU records: a record with recordPacking=xml is
1169 modified with a new root element <yaz_record> if the recordData contains
1170 multiple children elements. This is to make the record XML parseable
1173 RPN to Solr conversion: encode special characters.
1175 Generic Frontend Server: fix uinitialized member, stepSize.
1177 --- 4.2.4 2011/06/21
1179 Fix a bug in SRU decoding of records.. The database records stored
1180 had un-initialized memory, but it would only be seen with yaz_record_render
1181 and type_spec="ext" .
1183 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1185 --- 4.2.3 2011/06/17
1187 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1189 --- 4.2.2 2011/06/10
1191 Add new utilities to convert from CQL to CCL . These utilities have
1192 prefix cql_to_ccl defined in cql.h.
1194 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1195 lead to memory heap corruptions when ICU utilities were in use.
1197 --- 4.2.1 2011/06/07
1199 Make compilation work without Libxml2.
1201 yaz-client: remove redundant blanks in display of searchResult-1 term
1204 --- 4.2.0 2011/05/18
1206 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1207 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1209 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1210 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1211 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1212 Note that the CQL sortby spec is only converted when the GFS is already
1213 converting from CQL to RPN (cql2rpn element).
1215 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1216 specify whether to collapse delimitors or not. The existing nmem_strsplit
1217 do collapse (collapse parameter = 1).
1219 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1221 Rename internal func yaz_use_attribute_create. While non-static, this
1222 function is not declared in a public header.
1224 --- 4.1.7 2011/03/15
1226 Add -lCrun when linking with ICU on Solaris.
1228 More quicks character set conversions for OPAC records.
1230 --- 4.1.6 2011/03/10
1232 fix problem with record_render: records were converted (character set
1233 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1235 --- 4.1.5 2011/03/08
1237 SRU: add methods for handling DADS SRU-proxy facets.
1239 Separate OPAC record character set for ZOOM_record. yaz_record_render
1240 allows a character set given as charset=from/opacfrom,to where 'from' is
1241 the character set of a bibliographic record, 'opacfrom' is character set
1242 of OPAC record and 'to' is the target character set.
1244 --- 4.1.4 2011/02/21
1246 yaz-client: show may XML format records. Command show followed by 'format'
1247 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1250 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1253 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1255 --- 4.1.3 2011/01/27
1256 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1258 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1259 this package can be distinguished from other vendors.
1261 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1262 as determined by configure
1264 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1266 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1267 returns no error and no record, the present request is considered
1268 partial (only a subset of the records could be returned by backend), and
1269 so it is appropriate to set Present Status to partial-4.
1271 --- 4.1.2 2010/11/02
1273 Move yaz-config man pages to section 1.
1275 More documentation about Solr.
1277 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1278 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1279 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1280 peers on some Linux systems. However, in general that does not work
1281 so YAZ can not rely on that to work. Debian changed behavior in this
1282 respect from Debian lenny to Debian squeeze (still testing as of Oct
1284 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1286 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1288 --- 4.1.1 2010/10/05
1290 Fix yaz-config output: echo_source not set correctly by configure.
1292 --- 4.1.0 2010/10/05
1294 Solr Web Service support for yaz-client and ZOOM.
1296 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1298 --- 4.0.12 2010/08/17
1300 Z39.50 facet support. Facet specifications are passed for search in
1301 other-information with ASN.1 as defined in facet.asn and OID
1302 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1303 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1304 3 is limit (number of entries to get in response). yaz-ztest returns
1305 dummy facets if a client asks for them.
1307 --- 4.0.11 2010/07/09
1309 CCL fixes: bug 2895 and bug 3539.
1311 GR1-display: add comma in display - was removed by mistake in
1314 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1316 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1318 --- 4.0.10 2010/06/18
1320 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1321 result set from a connection. The result set will be on its own
1322 thereafter; no operations on it will perform retrievals from a target.
1323 Only cached copies are returned.
1325 ZOOM C:fix case for HTTP servers responding with Connection:close.
1326 Ensure that if there is a current task it is resumed (like fetching
1327 more records in a result set) . Bug #3484.
1329 PQF parser: use odr_atoi for Odr_int (not atoi)
1331 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1332 values that contain any non-digits are treated as string attributes
1333 (previously decoding only checked for leading character ([0-9]). PQF
1334 encoding: attribute string values are not surrounded by double-quotes.
1336 --- 4.0.9 2010/05/21
1338 New utility for managing threads - thread_create.h.
1340 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1341 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1342 but YAZ' implementation do.
1344 Fixes for yaz_cond-functions on Windows 7.
1346 DLL export more symbols.
1348 zoomsh: show record do NOT render opac.
1350 Remove *.la files from Debian and RPM packages.
1352 --- 4.0.8 2010/05/11
1354 Debian package libyaz-dev depends on libgnutls-dev again (was
1355 removed in YAZ 4.0.6, but due to Libtool it is still needed
1356 even though yaz-config do not list libgnutls libs).
1358 ZOOM: Use only one WRBUF for returning string results for
1359 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1361 ZOOM: ZOOM_connection do not use a shared pointer to
1362 ZOOM_resultset after ZOOM_resultset is destructed by
1363 user. Reverts to YAZ 4.0.4 behavior.
1365 --- 4.0.7 2010/05/04
1367 record-conv: fix problem with at least one XSL conversion -
1368 due to probably incorrect usage of XML XSL documents.
1370 --- 4.0.6 2010/04/29
1372 Fix yaz-config for static mode and the use of SSL (gnutls).
1374 --- 4.0.5 2010/04/29
1376 Forward decl timeval struct in mutex.h and gettimeofday.h.
1378 yaz-config: fix 'static' mode linking.
1380 --- 4.0.4 2010/04/28
1382 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1383 are wrappers for pthreads or Windows. For Windows these are put in
1384 a separate DLL: yaz_cond4.
1386 libyaz.la (whole source) is compiled with thread. If thread support
1387 is enabled enabled, all source of YAZ is compiled with treading support.
1388 This allows core utilities such as yaz_log to use thread facilities.
1389 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1390 thread utilities. This commit moves mutex utilities (mutex.c) from
1391 libyaz_server.la to libyaz.la.
1393 yaz-json-parse displays leading text until error.
1395 --- 4.0.3 2010/04/09
1397 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1398 patch from Giannis Kosmas.
1400 SRU: no longer URL encode SRU database. The URL for an SRU server is
1401 a URL and such is alreeady encoded - at least when given with leading
1402 http:// or https://. This reverts behavior to YAZ 3.0.50.
1404 Support for new MARC XML notation TurboMARC which like MARCXML is a
1405 complete representation of MARC/ISO2709.. This one, however, is more
1406 compact and allows for faster processing with XSLT. TurboMARC can be
1407 used in the marcdisp.h API, from the yaz-marcdump utility and from
1410 yaz-ztest can be configured - via the database - to perform certain
1411 delays when it performs operations search, present and single record
1412 fetch. This allows testers to make yaz-ztest act as a real or even slow
1413 Z39.50 server. Refer to the yaz-ztest man pages for details.
1415 --- 4.0.2 2010/03/09
1417 wrbuf_destroy allows NULL WRBUF passed to it.
1419 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1421 Add ZOOM_connection_close.
1423 No fixed size buffers for ZOOM shell - bug #3257.
1425 tstodr: make it work on s390 platform.
1427 New icu iterator-functions. The new icu_iter-functions makes it possible
1428 to use ICU chains from many threads.
1430 yaz-client: better syntax check for show command.
1432 --- 4.0.1 2010/01/26
1434 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1437 New simple local-file XML include facility which allows file glob-patterns.
1438 Refer to yaz/xml_include.h.
1440 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1443 ZOOM_record_get supports new parameter "format" which makes it format XML
1446 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1447 JSONText in ECMA-262) is JSONValue, not JSONObject.
1449 --- 4.0.0 2010/01/20
1451 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1452 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1454 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1455 POSIX/Unix builds .so with major version 4.
1457 Remove old LOG_-defines from log.h. They have been obsolete and
1458 undefined by default for the last 5 years.
1460 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1462 GFS: Remove socket (int *fd) from search_rr handler. The socket
1463 descriptor ptr is a facility that allowed a search handler to supply
1464 a socket which would serve as a callback - when search was complete.
1465 This facility has now been in use for years.
1467 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1468 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1469 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1470 returns 'const char *' rather than 'char *. The returned string is
1471 read-only and should not be modified by applications. COMSTACK cs_close is
1472 now a void function - it no longer returns int. No applications check for
1473 the value and the implementations has always returned 0.
1475 ZOOM: use size_t for scan hit counts and str size. Functions
1476 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1477 occ (hit count) and len (string length) are now of type size_t pointer
1478 rather than int pointer. This is to be able to represent large hit counts
1479 and to also just to use the proper type for string length (strlen result).
1481 New JSON parser. Refer to include/yaz/json.h .
1483 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1484 Used to be int in some cases. Many wrbuf_-functions used to return an int
1485 indicating some length.. These return values were never used. And so they
1488 ODR: odr_malloc, odr_total now takes size_t for size.
1490 clone_z_type: fix leak; occurred for encoding failures.
1492 --- 3.0.52 2009/12/03
1494 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1495 bug was introduced in 3.0.51.
1497 --- 3.0.51 2009/12/02
1499 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1501 tcpip comstack: fix leak for getaddrinfo.
1503 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1504 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1505 Decoding of SRU "path" database is performed by private function
1506 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1507 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1509 yaz-client: honor base command for SRU. Change when database setting
1510 is applied for SRU and ensure it is kept when a connection is reset.
1511 Change also the way errors are displayed or SRU (decoding of packages).
1513 --- 3.0.50 2009/11/02
1515 Add support for extra request / response data for SRU codecs and GFS.
1516 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1517 for extra data response buffer and length. For the GFS, both request
1518 and response data (XML) is carried in extra_args and extra_response_data
1519 for the search handler. Patch by Ko van der Sloot.
1521 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1522 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1523 10010). This fixes bug #2113.
1525 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1526 cmdfile included a 'quit' command that would result in a memory violation.
1528 --- 3.0.49 2009/10/01
1530 Make a number of functions defined in xmlquery.c static. These have
1531 never been declared in a public header file (yaz/xmlquery.h) and was
1532 made public by mistake.
1534 Improve speed of character conversions (iconv utilities). This makes
1535 conversions from MARC-8 faster.
1537 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1538 unless type desired is "raw". This will prevent type "xml" from
1539 returning ISO2709 .. Which obviously can not be XML parsed.
1541 Fix memory leak in ZOOM that would occur if option apdulog was used
1542 on a re-used connection.
1544 Frontend server logs HTTP requests.
1546 Frontend server now sends Z39.50 close when it times out (sesssion has
1547 been idle for too long). Versions 2.0.30 and earlier also sent close.
1548 But due to a mistake this was disabled in all versions after that, i.e.
1549 the server would just close the socket immediately.
1551 yaz-client emits a better message when receiving an unrecognised
1552 userInformationField.
1554 Skip zero-length subfields when decoding ISO2709. This rare case happens
1555 if a record has two FS characters in a sequence. Without this patch
1556 there would be a reference beyond char array in using_code_len fragments
1559 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1561 --- 3.0.48 2009/08/28
1563 The show command offered by the zoomsh command now takes a 3d optional
1564 parameter type which is what is passed to ZOOM_record. If the type
1565 argument is omitted, "render" is used.
1567 RPN to CQL conv may use USE string attributes (bug #2978).
1569 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1571 --- 3.0.47 2009/07/08
1573 Function yaz_xml2query allows a diagnostic element in the PQF XML
1574 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1575 code and additional info respectively.
1577 The BER BOOLEAN is now the integral type Odr_bool which still happens
1578 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1579 typedef'd to Odr_int. This is still an integral 'int', but it may be
1580 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1581 ASN-1 compiler as well as programs has been updated to use the new types.
1583 --- 3.0.46 2009/06/08
1585 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1586 only the bibliographic record was rendered. For type=opac, an OPAC
1587 record is only returned if it is present.
1589 iconv: small fix for encoding of advancegreek.
1591 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1593 yaz-client: option auto_reconnect=on really reconnects.
1595 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1597 server: avoid null ptr ref for for yaz_poll errors.
1599 build: fix RPM build for RHEL 5.3.
1601 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1603 --- 3.0.45 2009/03/31
1605 Fixed bug #2709: TCP connect returns Invalid argument.
1607 Fixed compilation for mingw.
1609 Honor charset for raw records (ZOOM_record_get).
1611 Fixed use of errno for threaded mode that was seen on Solaris 10.
1613 Fixed argument passing with blanks in value for Windows Service.
1615 Disable YAZ' own log rotate by default (no 1 GB limit).
1616 The variable l_max_size which specifies the log file limit is set to 0
1617 (DISABLED): This is due to the fact that YAZ is most often deployed using
1618 logrotate. Also YAZ can not perform log rotate because of unsufficient
1619 permissions (setuid).
1621 --- 3.0.44 2009/02/17
1623 List supported encodings in man page for yaz-iconv.
1625 Fixed missing SSL libs for --libs output
1627 Re-established OID record syntax application-xml. Nobody should use it
1628 but we don't want to change soname because of this symbol being absent.
1630 --- 3.0.42 2009/02/02
1632 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1634 Added member named_result_sets for init handler struct for the GFS. This
1635 allows a server to disable named result sets.
1637 Removed OID record syntax application-xml.
1639 Added support for rule-based transliterator for ICU wrapper of YAZ.
1641 Fixed bug #1902: yaz-icu XML output.
1643 Make YAZ checks Emacs friendly.
1645 BITSTRING value shows value. Bug #2346.
1647 ISO2709 decoding: skip control characters from indicator data.
1649 Omit sort key by default in yaz-icu's output.
1651 Allow combined single char options (again) for YAZ' options function.
1653 Utility yaz-marcdump got option to display YAZ version (-V).
1655 Allow YAZ to use ICU 3.4.
1657 Added new ICU test case which illustrates removal of diacritics.
1659 --- 3.0.41 2008/12/29
1661 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1663 --- 3.0.40 2008/12/29
1665 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1668 Fixed bug #2352: yaz-marcdump crashes for certain record.
1670 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1672 Added support for Danmarc2 to UTF-8 conversion.
1674 Added support for ISO5426 to UTF-8 conversion.
1676 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1677 implementation version.
1679 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1681 --- 3.0.38 2008/11/10
1683 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1684 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1686 ZOOM C now interprets databaseName option for ZOOM connection as path
1689 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1691 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1693 Dummy Libxml2 types no longer defined in headers of YAZ'.
1695 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1698 --- 3.0.36 2008/09/26
1700 Various ODR chapter fixes.
1702 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1704 Added missing source for Windows compilation, mutex.c.
1706 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1708 For SRU connections in ZOOM all records up to "count" are now fetched.
1710 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1711 in Windows due to bad error handling for Libxml2.
1713 Added facility for sending arbitrary records (ASN.1 any) using
1714 ZOOM C's Extended service update. Patch by Sam Reynolds.
1716 New options for ZOOM C's connection, logapdu which makes ZOOM log
1719 --- 3.0.34 2008/06/18
1721 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1723 --- 3.0.32 2008/06/12
1725 Fixed memory violation that could occur when decoding UTF-8. This bug
1726 was only present in 3.0.30 of YAZ.
1728 --- 3.0.30 2008/06/06
1730 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1731 GNU TLS is used by default (if found).
1733 yaz-ztest returns OPAC records if a client asks for OPAC.
1735 Improved speed of MARC-8 encoding.
1737 Added support for lossy and loss-less MARC-8 encoding.
1739 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1741 Added new Windows Service wrapper (sc).
1743 yaz-client's itemorder command may now send a file.
1745 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1747 Added new function yaz_log_xml_errors.
1749 Allow (but warn) unknown XML attributes in MARCXML parsing.
1751 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1753 The UTF-8 to MARC-8 conversion now uses a different set of characters
1754 for Greek symbols. Bug #2120.
1756 --- 3.0.26 2008/02/21
1758 Added yaz_daemon (daemon.h).
1760 Fixed bug #2068: pkg-config trouble
1762 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1764 --- 3.0.24 2008/01/28
1766 Document --with-xml2 option.
1768 Added OPAC XML XSD (etc/opacxml.xsd).
1770 Allow glob mask for name attribute in retrieval element for the
1771 generic frontend server's retrieval facility.
1773 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1774 except POLLIN/POLLOUT.
1776 Fixed error handling in cs_listen. Bug #2037.
1778 --- 3.0.22 2008/01/20
1780 Fixed version in yaz/yaz-version.h.
1782 Fixed bug #2027: Crash when closing connection.
1784 Changed configure so that ICU support is only enabled if only ICU
1785 and Libxml2 is available (because the ICU chain is XML based).
1787 --- 3.0.20 2008/01/15
1789 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1790 is built. Only this DLL depends on the ICU runtime.
1792 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1793 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1795 Changed license of CCL module to 'Revised BSD'. After consultation with
1796 remaining members of the original EUROPAGATE consortium, we are re-issuing
1797 the CCL module without a separate license. The software was developed by
1798 Index Data as part of a research project. The special license was included
1799 to help feed usage information back to the project consortium to support
1800 project evaluation. At this time, the project consortium has long-since
1801 disbanded, and the majority of the original principals have retired. At the
1802 same time, we have significantly modified the software during the following
1803 years, to the point where very practically no original code remains. To
1804 simplify re-use of the software, we have contacted those members of the
1805 consortium who could be reached, and agreed to re-issue the module as a
1806 proper part of the YAZ package.
1808 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1810 CQL closer to being version 1.2 compliant. CQL also allows free-form
1811 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1814 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1815 bug could make Extended services handling crash in the ZOOM layer. This
1816 bug was only present in YAZ 3.0.18.
1818 --- 3.0.18 2007/12/19
1820 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1823 yaz-marcdump reads and writes collection wrapped records.
1825 Handle OPAC for record conversion module.
1827 Fixes for ICU wrapper.
1829 Allow ICU libs to be controlled with --with-icu .
1831 --- 3.0.16 2007/11/12
1833 Added yaz_poll which is a wrapper for select/poll. When poll is available
1834 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1835 sockets to be in use.
1837 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1838 functionality through an XML based configuration (ICU chain). This system
1839 is useful for search facilities such as Pazpar2 and Zebra that needs to
1840 perform tokenization of indexed material. The ICU code in a separate
1841 library libyaz3_icu.a.
1843 Added HTTP tunnel facility for COMSTACK, bug #1752.
1844 This is a facility that allows a Web proxy, such as squid, to tunnel
1845 Z39.50 traffic. This facility is "transparent" to must applications
1846 using YAZ. It's enabled by using pseudo transport connect: followed by
1847 the proxy address, followed by command, then follwed by he regular
1848 "virtual" addresss. For example,
1849 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1851 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1853 --- 3.0.14 2007/09/21
1855 Fixed bad memory reference in ZOOM_record - cuased by member not being
1856 initialized. This was a problem only in YAZ 3.0.12.
1858 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1859 fields were not removed.
1861 Changed the way C code is generated from codetables.xml. Made a MARC-8
1862 conversion trie for each characterSet section rather than codeTable.
1863 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1864 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1866 --- 3.0.12 2007/09/12
1868 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1869 from ZOOM_record_error).
1871 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1873 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1875 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1877 Better SRW-to-Bib-1 diagnostic mapping.
1879 ZOOM C and yaz-client announces SRU version 1.2 by default.
1881 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1884 Fixed in yaz_sru_decode to allow other version than 1.1.
1886 --- 3.0.10 2007/08/22
1888 Added support for SRU scan for ZOOM.
1890 Added support for the use of the older versions or Extended Service
1891 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1892 set to the version , 1=first, 2=second, 3=third. The third version is
1893 what ZOOM C has used so far. And that, obviously, is the default.
1895 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1896 therefore in Zebra and in SimpleServer-based applications). The new
1897 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1898 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1899 which is passed into the back-end search callback function.
1901 Added support for HTTP Basic authentication in clients: the SRU/W
1902 codec encodes the username/password elements of the PDU structure
1903 appropriately, and these may be set using the "user" and "password"
1904 options in ZOOM-C applications (the same options that are used for
1905 Z39.50 authentication).
1907 --- 3.0.8 2007/06/25
1909 Fixed bug #1208: SSL appears to be broken in ZOOM.
1911 Fixed bug #1206: Libxml2 include path weirdness.
1913 Added oid_name_to_dotstring.
1915 Allow elementSetName to be specified for ZOOM C record update.
1917 Allow waitAction to be specified for ZOOM C based for Extended Services.
1919 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1920 syntax OID. Bug introduced in YAZ 3 series.
1922 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1924 --- 3.0.6 2007/06/06
1926 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1927 directory. yaz-client now reads commands from file given by option -f
1928 if specified; then tries to read .yazclientrc in current directory.
1929 Failing that, it reads .yazclientrc from user's home directory.
1931 Added support for correlationInfo Note and ID for Record Update via
1934 Added yaz-client command querycharset which specifies character set for
1935 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1936 (termListAndStartPoint).
1938 Charset ISO5428:1984 is an alias for ISO5428-1984.
1940 Implemented a way to perform scan in a result set using Z39.50. This
1941 is achieved by attaching the result set name in the characterInfo
1942 (type InternationalString) of OtherInformation in the Scan Request PDU.
1943 The result set is identified in the otherinformation by the new OID:
1944 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1945 This allows for scan in result set and faceted search . Zebra did some
1946 of this in the APT term using attribute type 8 and value being result
1947 set. Using the OtherInformation approach for this is cleaner and easier
1948 to work with in proxies and the like. This facility can be used in
1949 yaz-client using new command setscan which takes a result set as first
1950 argument, start position (APT) as second.
1952 Changed decoding of SRU XML packed records to deal with servers that
1953 have recordData with XML data with multiple root nodes. Also make
1954 comparison for recordPacking case insensitive. Again, one server
1955 returns "XML" where others return "xml".
1957 For SRU responses allow Content-Type application/xml as well as text/xml.
1959 --- 3.0.4 2007/05/21
1961 Fixed bug in character set conversion of BER strings. Bug introduced
1964 --- 3.0.2 2007/05/08
1966 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1968 For OID class, use oid_class consistently.
1970 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1973 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1974 character set for bibliographic information interchange". By Giannis Kosmas.
1976 Added documentation on new OID API.
1978 --- 3.0.0 2007/05/02
1980 Changes to generic frontend server interface: added new member
1981 'query_charset' for bend_initrequest structure. A backend init handler
1982 should set this member to its native character set for query terms.
1983 When defined, the frontend server logic will announce this character set
1984 to a client if the negotiationModel bit is set by the client. All server
1985 implementors are encouraged to specify this. If a backend server does not
1986 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1988 Added CCL utility to remove terms (stop words) from resulting RPN
1989 tree. This is handled by functions with prefix ccl_stop_words_ .
1991 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1992 terms in RPN queries.
1994 Clean-up the CCL API. Moved some internal structures from ccl.h to
1995 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1996 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1997 This is replaced by ccl_parser_find_str which takes a string instead.
1999 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2000 libyaz.la is the core of YAZ except the generic frontend server and
2001 does not depend on POSIX threads anymore. libyaz_server.la is the
2002 generic frontend server facilities and uses POSIX thread functionality
2003 if available. The libyaz.la no longer depends on POSIX threads because
2004 the number of global structures is limited. NMEM no longer re-uses blocks
2005 between threads ; it simply free's memory immediately but allocates in
2006 "large" chunks as usual. We don't expect any performance penalties
2007 because of this. The yaz_log system is still using a global log_level so
2008 caution must be taken when modifying it with yaz_log_init_.. +
2009 yaz_log_mask_str. This, however, should not cause any trouble because
2010 these functions are called during initialization of application code
2011 anyway. `yaz-config --libs server` returns libs for server applications;
2012 `yaz-config --libs` returns libs for non-server applications.
2014 New OID database - with public definitions in oid_db.h. Removed old OID
2015 database including the head oid.h and definitions such as enum oid_value
2016 and struct oident. The new OID database uses the same string names as
2017 before but the 'protocol' is gone. There are now only two representations
2018 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2019 converts from string to OID; functions with prefix yaz_oid_to_string
2020 converts the other way.
2022 Change to emit_term() in CQL-to-PQF query translation: when a term has
2023 the /regexp relation modifier, do not process it for leading and
2024 trailing "^" and "*", which have quite different meanings in regular
2027 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2028 write handlers no longer carries a 'last' parameter. This will make
2029 yaz_iconv flush "less" characters. A flush is performed by call to
2030 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2032 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2033 removed, because function yaz_query_to_wrbuf does the same.
2035 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2036 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2038 Deprecated MARC utility functions removed.
2040 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2043 Branch split: YAZ_2_1_55_branch
2045 --- 2.1.54 2007/03/16
2047 Fix to ZOOM-C so that transparent reconnection is properly handled on
2048 connections that are in asynchronous mode.
2050 Fixed compilation on OpenBSD 4.0.
2052 Large strings in GRS-1 records are now properly displayed in yaz-client.
2054 Added character conversion support for "advancegreek"; based on patch from
2057 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2058 sequence is met. Before the error was not set so it would be unknown.
2060 Adjust yaz-marcdump MARC reader so that it skips until record separator
2063 --- 2.1.52 2007/03/07
2065 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2066 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2067 fd_set structure used as a bitmask for the FDs to be selected on.
2069 Using ACX_PTHREAD macro to check for POSIX threads.
2071 Fixed have-vsnprintf check.
2073 --- 2.1.50 2007/02/23
2075 Fixes for configure on BSD. Bug #900.
2077 Added snprintf/vsnprintf wrappers for systems that don't have
2078 limits (heavens forbid).
2080 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2081 created before all previous tasks were completed and removed from the
2082 task queue, the new task could be removed by a mistake.
2084 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2086 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2088 Fixed bug #832: Problem with MARC/charset in yaz-client.
2090 Fixed bug #668: save command line history for yaz-client.
2092 Fixed bug #830: pkg-config support.
2094 --- 2.1.48 2007/01/23
2096 Extended ZOOM result set options with two options that may be read by
2097 a client: resultSetStatus and presentStatus with values as specified for
2099 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2101 Fixed bug #827: Using SSL fails on Debian etch.
2103 Fixed bug #826: Weird looking chars for set of MARC records.
2105 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2106 that is treated as an ItemOrder with itemRequest being an XML document
2107 external. The value of "doc" is the content.
2109 Extended the GFS search facility. New member of bend_search_rr
2110 'estimated_hit_count' signals that hits is known to be an estmate
2111 (higher or lower than real hit count). New member 'partial_resultset'
2112 signals that the search was partial (hit count is lower or equal than
2113 real hit count). For Z39.50, the information is stored in resultSetStatus
2114 member of SearchResponse APDU. For SRU, the information is signalled
2115 via SRU diagnostic 59: "Result set created with valid partial results
2118 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2120 --- 2.1.46 2007/01/13
2122 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2124 Added ZOOM_connection_peek_event.
2126 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2127 the following new functions:
2128 ZOOM_event_nonblock, ZOOM_connection_process,
2129 ZOOM_connection_get_{socket,mask,timeout},
2130 ZOOM_connection_fire_event_{timeout,socket}.
2131 The existing blocking event handler, ZOOM_event, is a wrapper for the
2132 + blocking ZOOM_event_sys_{poll,select}.
2134 Implemented function ccl_xml_config which parses XML version of CCL
2135 configuration (bug #798).
2137 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2139 Added timings utility (yaz/timing.h)
2141 --- 2.1.44 2007/01/03
2143 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2146 Fixed bug #779: Rotation of apdu.log fails.
2148 Fixed for character set conversions:
2149 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2150 Honor G1 set in MARC-8 decoding.
2152 --- 2.1.42 2006/12/17
2154 Fixed bug #775: char conversion does not handle Alternative UTF-8
2157 Implemented function yaz_marc_read_line which parses MARC line format
2158 records. There is a wealth of formats out there. So far, this function
2159 reads line records produced by yaz_marc_write_line.
2161 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2162 more generic and easier to remember(!) options: -i format and -o format
2163 which specifies input format and output format respectively - where
2164 format is one of "marc", "marcxml", "line", "marcxchange".
2166 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2167 does not print anything except warnings for records.
2169 For yaz-marcdump, added support for MARC split into files (-s) with a given
2172 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2173 spec, at http://www.loc.gov/standards/sru/record-update/
2174 This has changed the binary layout of the following structs:
2175 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2176 bend_update_rr . Patch by Ko van der Sloot.
2178 Added GFS utility function bend_assoc_is_alive which returns 1 if
2179 association is still alive (client is connected); 0 otherwise (client
2180 closed connection). This allows busy servers to stop working for
2183 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2184 been a separate piece of software. This version of ziffy has been modified
2185 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2187 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2189 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2190 Client code may now interrogate options such as "init_opt_sort" to
2191 find out whether the server claims to support various options.
2193 --- 2.1.40 2006/11/27
2195 Added utilities yaz_{set,get}_esn to set/get element set name from
2198 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2199 of YAZ and has been so since YAZ 2.1.10.
2201 Implemented ZOOM_record_error which returns error information for
2202 record (surrogate diagnostic).
2204 --- 2.1.38 2006/10/31
2206 Updates for SRU Update by Ko van der Sloot:
2207 1. Changed name from "operation" to "action"
2208 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2209 versions in the code, marked as 'backward compatible'.
2210 3. Added diagnostics for SRU Update.
2212 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2214 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2216 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2218 For GFS, fixed problem with SRU diagnostic 'First record position out of
2219 range' being issued for 0 hits.
2221 zoomtst10 part of Windows Build.
2223 --- 2.1.36 2006/10/13
2225 Implemented yaz_filepath_comp which splits a path into file path
2226 components (required by Zebra 2.0.3+).
2228 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2229 BSD inspired license until now so this should not have any real impact on
2230 anybody. See http://www.opensource.org/licenses/bsd-license.php
2232 Fixed bug #687: Missing log lines.
2234 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2237 Fixed bug #689: SRU diagnostics to be added.
2239 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2240 whether a connection is idle (no more work do do).
2242 --- 2.1.34 2006/10/04
2244 Change type of optval from long to int for invocation of setsockopt with
2245 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2247 Added support for specifying the max log file size for the Generic
2248 Frontend Server. The size is given with option -r.
2250 --- 2.1.32 2006/09/21
2252 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2254 --- 2.1.30 2006/09/17
2256 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2259 Fixed bug in Generic Frontend Server that could cause a server to stop
2260 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2262 For the generic frontend server, the maximum record size is used as maximum
2263 size of incoming packages (SRU + Z39.50). The value until was previously
2264 only used in Z39.50 Init negotiation and, later, in a session controlled
2265 sizes of records returned. This is controlled using -k option. It can be
2266 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2268 --- 2.1.28 2006/09/04
2270 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2273 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2275 New option for yaz-marcdump -lpos=value which allows setting a portion
2276 of MARC header to a certain value.
2278 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2280 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2281 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2283 --- 2.1.26 2006/08/15
2285 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2288 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2290 --- 2.1.24 2006/08/08
2292 Fixed MARC ISO2709 encoding routines to deal with character set
2295 Minor changes to GFS logging. Database included in search request log
2298 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2299 cached/multiple records.
2301 Shared libraries are built by default on Unix+configure.
2303 Changed cql2pqf transformation to use a different evaluation order. The
2304 new order is: always, relation, structure, position, truncation, index
2305 and relationModifier. Old order was: always, relation, relationModifier,
2306 structure, index, position, truncation. Note that the the latter ones
2307 override former ones for identical attributes.. The new scheme means that
2308 it is possible to override any existing attribute with a relationModifier.
2309 And also that it is possible to override everything for the index rule
2310 (except the ones listed in relationModifier). No order is perfect but this
2311 one, we believe, covers more real cases.. The "always" should have been
2312 called "default", since the attributes there can be overridden with all
2315 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2316 compilation phase, but also for yaz-config --cflags output. This allows
2317 us to have public headers with Libxml2 stuff in them . It should also,
2318 eventually, make Libxml2 checks redundant in packages using YAZ, such
2321 --- 2.1.22 2006/06/15
2323 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2324 stored in uri, message and details.. Previously diagnostics were stored
2325 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2326 compatibility.. but he's probably the only one affected, so.
2328 Added support for CCL, compiled on the client side, in ZOOM-C. This
2329 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2330 input; the resulting query objects can be used for for searching with
2331 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2333 YAZ' configure searches for OpenSSL by default.
2335 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2336 SL_CTX_use_certificate_file. See
2337 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2338 for more info. Thanks to Ko van der Sloot.
2340 --- 2.1.20 2006/06/02
2342 Bug #600: SRU GET, POST support for yaz-client. Introduced
2343 command 'sru' which selects method SOAP/GET/POST.
2345 Allow missingValueAction to be specified for the sortspec string -
2346 function yaz_sort_spec. By default, the missing value action is null.
2347 Use ! to specify "abort". Use = followed by stringvalue to specify default
2350 Ensured that Present-handler (if defined) is called in GFS before any call to
2351 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2352 searchRetrieve requests.
2354 Documentation for YAZ is now based on the Docbook XML/XSLT using
2355 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2356 is no longer depending on jade/openjade or docbook-to-man scripts.
2357 PDF is no longer part of the distribution - but can optionally be
2358 made using DSSSL/jadetex or FOP.
2360 Added retrieval handling support in Generic Frontend Server to support
2361 conversion between MARC/XML as well as XSLTtransforms. See
2362 etc/yazgfs.xml for an example.
2364 Added Authentication support to Generic Frontend Server in SRU
2365 mode. Authentication using HTTP Basic is supported, as is the use
2366 of 'x-username' and 'x-password' parameters in the request itself.
2368 Added support for a new character set MARC8s identical to MARC8 except
2369 that it converts combined characters to single Unicode characters in the
2370 Latin-1 range (when possible).
2372 --- 2.1.18 2006/04/24
2374 ASN.1 compiler 0.4: generates brief Doxygen file header for
2375 generated .h/.c files.
2377 Utility yaz_iconv now supports conversion to MARC-8.
2379 New facilities for the MARC module. The reading - and writing of
2380 content are separate methods for the yaz_marc_t handle. The following
2381 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2382 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2383 format). Write functions have prefix yaz_marc_write_.. The existing
2384 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2385 available. Removed support for OAI-MARC and simplexml (not the
2386 simplexml from PHP5).
2388 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2389 to be returned for this connection.
2391 --- 2.1.16 2006/03/31
2393 Allow multiple languages and charsets to be specified with
2394 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2395 negcharset iso-8859-1,utf-8
2397 Translation of proximity nodes from CQL into PQF now works.
2399 Moved to automake 1.8, 1.9.
2401 Added function yaz_log_set_handler which allows a log handler to be
2402 installed. This handler will be called for all log messages. Output
2403 to file is also produced; but that can be disabled by passing NULL
2404 fname to yaz_log_init_file.
2406 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2408 For SRW (including GFS), accept application/soap+xml as content-type
2411 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2412 produces NO stylesheet reference even if a default stylesheet is specified
2415 --- 2.1.14 2006/03/14
2417 Updated Windows package to include yazd.dll + yazd.lib for the
2418 Development component.
2420 If the environment variable YAZ_LOG is set, then it is used as a
2421 string indicating the default level of logging to use if not
2422 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2423 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2424 used as before. So, for example, to omit warnings from YAZ logging,
2425 export YAZ_LOG=-warn
2427 cql_transform() now map structure and other attributes before indexes,
2428 so that index-specific structures and other attributes can override
2429 defaults. So now a combination of mapping specifications such as:
2431 index.dc.date = 1=date-modified 4=5
2432 does the right thing.
2434 cql_transform() now also respects the "always" mapping specification,
2435 which establishes an initial set of attributes to be used for all
2436 terms except where overridden by more specific attributes associated
2437 with the index, relation or modifier.
2439 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2440 which mode to use; one of "post", "get" or "soap" (SRW, default).
2442 Fixes for yaz_iconv routines: changed trie-based character set conversions
2443 to use only non-negative values for bit fields due to Sun's C compiler not
2444 supporting negative values.
2446 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2447 sequences where not read correctly. Fix by Rustam Usmanov.
2449 Updated win/makefile to use options, settings which makes things
2450 compile with VS C 2005.
2452 --- 2.1.12 2006/02/01
2454 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2456 In ZOOM socket code, use select instead of poll on MacOSX.
2458 ZOOM-C now support client-side compilation of CQL into RPN that is
2459 sent to the server, enabling CQL to be used against all Z39.50
2460 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2461 ZOOM_query object, and submit it using ZOOM_connection_search().
2462 The CQL-to-RPN translation uses a configuration file, the name of
2463 which must be specified in the Connection's "cqlfile" option.
2465 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2466 function, which takes as its start-term parameter a ZOOM_query object
2467 (which may have had either CQL or RPN set into it).
2470 --- 2.1.10 2005/11/29
2472 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2473 GFS to support this as well. Backend handler, bend_srw_update, does the
2474 update work. Code contributed by Ko van der Sloot.
2476 Allow retrieval of Search Result-1 information in ZOOM by the use of
2477 options that are attached to a result set. ZOOM documentation updated
2480 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2481 UTF-8 conversion. Patch by Raj Patel.
2483 Added option -m to GFS to control formatting of timestamps in log file.
2485 Added 'exit' as synonym for 'quit' in yaz-client
2487 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2488 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2489 for the new members. Patch by Ko van der Sloot.
2491 Added support for SRU POST. It is supported for content-type
2492 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2494 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2495 Instead make the library libyaz.la multi-threaded. Threading as a whole
2496 can still be disabled by configure option --disable-threads. Previosly,
2497 with older GLIBCs there were problems with MT libs under Apache. This
2498 has now been fixed a long time ago.
2500 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2503 CQL module modified to be case insensitive for relations/indexes/operations.
2505 Fixed bug in CQL transform code: incorrect value relationModifieder
2508 Added 'show all' command for yaz-client which retrieves all results
2511 Added new yaz-client, xmles, which takes a (private) OID and
2512 a document to be sent as an extended service request.
2514 Describe new yaz-client commands wait_response and set_auto_wait.
2516 Increase TCP/IP listener backlog from 3 (which I am guessing was
2517 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2518 that the socket will queue as many incoming connections as it's able
2519 to handle ongoing connections. In other words, it will never now
2520 refuse a connection that it would be able to handle merely because
2521 it's not got around to accepting() enough of the pending connections
2522 yet. This is the behaviour anyway under Linux, where the listen()
2523 argument is ignored; but not under BSD and on systems such as
2524 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2525 YAZ-based servers should now be uniform across operating systems in
2528 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2529 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2530 This allows yaz-marcdump to read large MARC batches (>2 GB).
2532 Modified all YAZ source files - except the source which is auto-generated
2533 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2536 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2537 corresponding to the existing *_setl() function. These allow option
2538 values containing arbitrary valuues.
2540 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2541 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2542 except that it returns an indicator of whether or not the sort
2543 criterion was accepted (0 for OK, -1 for invalid).
2545 --- 2.1.8 2005/06/07
2547 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2548 MARC output rather than returning "new" buffer.
2550 yaz-client warns about unknown init options.
2552 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2554 --- 2.1.6 2005/05/24
2556 Added support for SRW sort in Generic Frontend Server. Patch
2557 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2558 sortKeys - or NULL if none is provided.
2560 Fixed bug #307: It was impossible to specify indefinite/no timeout
2561 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2564 Added support for multiple languages and charsets to be specified in
2565 ZOOM. Each charset/language is separated by a blank. If negotiation is
2566 in effect in init-response, Option
2567 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2568 Code based on patch by Vasiliy Osadchuk.
2570 Fixed bug #306: infinite recursion that occurred when calling
2571 yaz_log_level_init as the first call (before other log level or
2574 Fixed bug in scan handling in front end server: if preferred-Position-In-
2575 Response was non-present, a NULL pointer referece was performed.
2577 --- 2.1.4 2005/04/26
2579 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2580 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2581 now defined for all those error codes. So instead of putting 109 in
2582 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2583 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2585 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2588 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2590 Program yaz-client now exits and produces an error message if multiple
2591 Z39.50 servers are specified on the command line (none or one allowed
2594 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2597 --- 2.1.2 2005/03/16
2599 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2601 Fixed bug #272: Preserve spacing for CCL terms.
2603 --- 2.1.0 2005/03/14
2605 Added support for virtual hosts and multiple backend servers for
2606 the YAZ frontend server. The configution is XML based and
2607 support specificition of CQL to RPN mappings and explain information.
2608 See section "Virtual Hosts" in the YAZ manual.
2610 Extended OPAC display utility. OPAC display utility renders
2611 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2612 to supplement yaz_marc_decode_wrbuf.
2614 Fixed a bug in MARC decoder that could caused it to crash for some
2615 invalid MARC records. More diagnostics and warnings where added in
2616 XML output (warnings, etc are stored in comments).
2618 --- 2.0.34 2005/02/08
2620 Fixes for UNIX domain sockets. Bug #261.
2622 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2624 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2625 Added yaz_marc_subfield_str which defines subfield lead string which is
2626 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2627 yaz_marc_endline_str which defines end of fields string used in
2628 YAZ_MARC_LINE format. Default string is newline.
2630 Experimental support for MarcXChange. This format can be produced
2631 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2632 http://www.bs.dk/standards/MarcXchange.xsd
2634 Added yaz-client commands scansize that sets maximum number of
2635 entries to be returned by scan.
2637 --- 2.0.32 2005/01/11
2639 Added support for SRW scan in yaz-client and Generic Frontend Server.
2641 * Added whereInList member to SRW Scan Term.
2643 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2645 Fixed NMEM system to return aligned blocks on the smallest boundaries
2646 that are suitably aligned for all possible types on the particular
2647 architecture YAZ is being built for.
2649 --- 2.0.30 2005/01/04
2651 Fixed numerious warnings that was issued with newer versions of GCC.
2653 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2654 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2657 Make YAZ Generic Frontend Server slightly faster.
2659 Enhance (and reduce) logging for Generic Frontend Server.
2661 Revert YAZ log system so that it flushes every write operation
2662 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2664 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2665 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2666 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2667 will effectively disable old definitions.
2669 --- 2.0.28 2004/11/09
2671 Added yaz_log_time_format which specifies log format using
2674 Added yaz_log_module_level which returns mask for a module. Value
2675 is non-zero mask a if module is enabled; zero if disabled.
2677 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2678 in include/yaz/cql.h.
2680 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2682 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2684 Fixed bug #172: RPM builds does not enable SSL.
2686 Doxyfile.in part of dist. Doxyfile generated by configure.
2688 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2689 are given and the corresponding component does not exist.
2691 Extend CCL documentation in YAZ reference. Describe r=r.
2693 --- 2.0.26 2004/10/01
2695 Fixed MARC->MARCXML conversion to properly deal with
2696 fields, subfields, indicators having non-ASCII characters.
2698 Fixed MARC->MARCXML conversion so that ASCII control characters
2699 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2702 Added YAZ GFS support for conversion from Z39.50 surrogate
2703 diagnostics to SRW surrogate diagnostics.
2705 Bug fix: YAZ GFS did not return schema in explainResponse.
2707 --- 2.0.25 2004/09/30
2709 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2710 now converts recordSchema to elementSetName as well as schema URI.
2712 Fixed bug in COMSTACK that prevented HTTP request packages from being
2715 --- 2.0.24 2004/09/29
2717 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2718 does not require white-space before and after the dash in a range, e.g.
2719 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2722 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2723 due to new GCC removing "redundant" code.
2725 Added yaz-client commands scanpos and scanstep that sets preferred
2726 position and step-size for scan.
2728 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2730 Added CCL utility ccl_qual_buf which parses one or more CCL
2731 spec lines in a buffer.
2733 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2734 of name and value - ignoring empty lines and comments.
2736 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2738 Added odr_get_element_path which returns current element path for an
2739 ODR handle. This utility is useful in error handling or user-defined
2742 Added ODR_PRINT utility odr_set_stream which is is a more generic
2743 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2744 to a write function and pointer to close function. The close function - if
2745 non-NULL - will be called during odr_destroy.
2747 Fixed bug in CCL parser where truncation char was not removed from
2748 right side when truncation=both was in effect.
2750 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2753 --- 2.0.23 2004/08/11
2755 Fix buffer overrun in CQL parser when dealing with proximity (%).
2757 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2758 to UTF-8/UCS conversion is now only based on codetables.xml.
2760 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2762 --- 2.0.22 2004/08/06
2764 Add support for more "commit changes" in ZOOM (uses Extended Services).
2766 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2769 Yet another small fix for configure of SSL.
2771 --- 2.0.21 2004/05/14
2773 Fix SSL libs for configure when --with-openssl=DIR is given.
2775 --- 2.0.20 2004/05/10
2777 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2779 SSL comstack now uses yaz.pem certificate file on server side
2780 by default. Certificate filename can be configured by calling
2781 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2783 Fix bug regarding multiple calls to ZOOM_connection_connect.
2785 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2787 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2788 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2790 ZOOM now allows inspection of X509 peer certificate for verification.
2791 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2793 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2794 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2795 as "modular" but it simplifies things.
2797 Added cs_get_peer_certificate to that returns peer X509 PEM.
2799 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2800 NULL if SSL is unavailable.
2802 Documentation about MARC decoding tools.
2804 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2806 --- 2.0.19 2004/03/30
2808 Rename CHANGELOG to NEWS to follow GNU style packing.
2810 Fix bug with missing initialization of member in init_diagnostics.
2811 This bug affects threaded version of GFS server.
2813 --- 2.0.18 2004/03/20
2815 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2818 Ensure zlib.dll is packed with Windows install.
2820 --- 2.0.17 2004/03/17
2822 Fix encoding of xsd:string to use text instead of CDATA.
2824 Fix endless loop in CQL parser with unbalanced ".
2826 Use a more compact way to store MARC-8 conversion tables.
2828 --- 2.0.16 2004/03/16 Debian only
2830 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2833 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2838 --- 2.0.15 2004/03/01
2840 Another fix for decoding of XML packed records.
2842 --- 2.0.14 2004/02/25
2844 Fixes for Chunked encoding. White space not ignored after length spec.
2846 Update NS and use default NS for SRW diagnostic elements.
2848 --- 2.0.13 2004/02/23
2850 Implement ZOOM_resultset_cache_reset which resets record cache.
2852 Implement ZOOM_resultset_sort which sorts a result set.
2854 Implement chunked HTTP transfer.
2856 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2858 --- 2.0.12 2004/02/16
2860 Added member 'schema' to bend_explain_rr structure so that backend
2861 can specify explain record identifier. Defaults to Zeerex 2.0.
2863 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2865 --- 2.0.11 2004/02/16
2867 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2870 Added init command for yaz-client which sends "extra" init request.
2872 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2873 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2875 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2877 Make ZOOM error code for "invalid query".
2879 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2881 --- 2.0.10 2004/02/05
2883 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2886 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2888 Added option -p <file> to make Generic Frontend Server to write PID file.
2890 Added option -D to put Generic Frontend Server in background on its own.
2892 Make ZOOM C recognize option "password". If unset, "pass" is used
2893 (for backwards compatibility).
2895 Fixed a bug in Generic Frontend Server that could make it crash if a
2896 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2899 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2900 Must be issued before open, in order to be in effect.
2902 --- 2.0.9-6 2004/01/12 Debian/Windows
2904 Make the SRU server more picky WRT unknown params, etc.
2906 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2908 New YAZ client command, options, that sets Z39.50 options.
2910 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2911 options from a string of tokens (one token for each option bit).
2913 Update SRW diagnostic code messages.
2915 --- 2.0.9-5 2004/01/07 Debian/Windows
2917 Handle user defined stylesheet for SRW/SRU.
2919 --- 2.0.9-4 2004/01/06 Debian/Windows
2921 Fix bug in decoding of Content-Length.
2923 --- 2.0.9-3 2004/01/06 Debian/Windows
2925 Fix a bug with decoding of XML packed records.
2927 --- 2.0.9-2 2004/01/05 Debian only
2929 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2931 Fix bug in SRW/SRU diagnostics decoding.
2933 --- 2.0.9 2004/01/05
2935 Fixed bug in Generic Frontend Server which could drop records exceeding
2936 preferred message size. Reported and fixed by Irina Dijour.
2938 Fixed calculation of package size for structured records in Generic
2939 Frontend Server. Reported and fixed by Irina Dijour.
2941 Fixed namespace for SRW/SRU diagnostics.
2943 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2945 --- 2.0.8 2003/12/22
2947 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2948 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2951 CQL changes to reflect recent changes to the specification:
2952 * Documentation talks about context sets instead of index sets.
2953 * Documentation talks about indexes instead of qualifiers.
2954 * The CQL-to-PQF transformer's configuration file now uses
2955 "index.set.name = <attributes>" instead of the old form
2956 "qualifier.set.name = <attributes>". (Both forms are still
2957 understood but the latter is deprecated.)
2958 * CQL terms with no explicit index specified are now interpreted as
2959 cql.serverChoice instead of srw.serverChoice (which of course
2960 behaves exactly the same.)
2962 --- 2.0.7 2003/12/16
2964 MARC conversion can now generate ISO2709 output in another
2965 character set. yaz-marcdump uses this facility if you invoke it
2968 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2969 functions from there can be used from C++.
2971 --- 2.0.6 2003/12/04
2973 Frontend server now transfers memory from decoded packages to stream
2976 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2977 references to show up.
2979 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2980 the ZOOM Abstract API. The older names for the same options are still
2981 also supported for the benefit of old applications.
2983 ZOOM-C supports "implementationId" and "implementationVersion" options
2984 to go along with "implementationName". These allow the user code to
2985 specify identification strings to be sent to servers.
2986 Add OID for the new ExtLite attribute set.
2988 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2989 as requested/supplid by Ere Maijala <ere@atp.fi>
2991 For generic frontend server, reverse the order of
2992 "toolkit-supplied / application-supplied" strings sent as implementationId,
2993 Name and Version. Also, remove the spaces around the slash. This brings
2994 the GFS in line with the behaviour of ZOOM-C on the client side.
2996 Add function ZOOM_scanset_display_term.
2998 yaz-client shows scan displayTerm if present.
3000 Utility yaz-iconv is now installed by default along with the man page
3003 Extend configure check for OpenSSL to use pkg-config where available (such
3006 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3007 server to specify uid/gid/mask for socket using the format
3008 unix:[user=uid,][group=gid,][umask=mask,]file=path
3009 If file= is omitted the existing format is assumed, e.g.
3011 in which case the mask is 0666 (rw for everybody).
3013 Major restructure of YAZ source. All source in libyaz is in src directory.
3014 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3015 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3017 Added man page for utility yaz-marcdump (used to be called marcdump).
3018 yaz-marcdump is installed by 'make install'.
3020 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3021 of incoming package failed.
3023 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3025 Change prototype of odr_perror: add const to message string.
3027 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3029 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3030 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3031 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3032 DNS lookup. There should not be any compatibility problems with this
3033 assuming that blocking=1 or 0 is used.
3035 Fix bad reference in UNIX comstack in function cs_addrstr.
3037 Fix for compilation on AIX.
3039 The generic front-end server (server/seshigh.c) now supports returning
3040 Init diagnostics to the client in User-information-field, in
3041 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3044 --- 2.0.4 2003/09/04
3046 Allow any CQL relation (not just all,any,exact,scr).
3048 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3049 that features the same UI.
3051 Implemented command update0 in YAZ client which is equivalent to
3052 update but uses old of Ext Update ASN.1.
3054 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3055 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3056 Previously no OID was used for this info.
3058 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3059 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3060 returns 'malformed search term' otherwise.
3062 SortResponse member resultCount now set to NULL in sort handler of
3065 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3068 Add three new utility functions for translating OIDs between various
3069 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3070 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3071 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3072 char *oid_to_dotstring(const int *oid, char *oidbuf);
3073 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3075 Reverted modifications for ES Update definition for z_IU0Update
3076 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3077 is back to YAZ 2.0.2.
3079 String value attributes for CCL parser.
3081 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3082 which their FirstSearch server returns in Init responses, sometimes
3083 carrying useful diagnostic information when Init fails. This has the
3084 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3085 "z39.50/oclcui.asn", where its definition is somewhat different from
3086 what OCLC document on their web-site, as required to interoperate with
3089 Support for anonymous authentication in yaz-client. Use the command
3092 * Fix the OID of the Index Data-local "admin" Extended Service from
3093 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3094 the 1000, which indicates a locally-defined OID, was a mistake.
3096 --- 2.0.3 2003/06/20
3098 Fix CCL directive @case handling so that it affects string match for
3099 both CCL keywords and qualifiers.
3101 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3102 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3103 Decoder has been updated with ASN.1 changes as listed in
3104 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3105 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3106 z_IUUpdate, remains unchanged.
3108 ZOOM_record_get may now return a record in a specific character set.
3109 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3110 "from" is the character set of record as returned by target. "to" is
3111 the character set to be returned. If omitted, "to" is UTF-8.
3113 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3115 New ODR utility, odr_getelement, which returns name of element for
3116 which encoding/decoding failed.
3118 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3119 in cases where a required element was omitted.
3121 Bug fix: some MARC8 sequences were not converted.
3123 New ZOOM option "step" which specifies number of records to be
3124 retrieved in one chunk. Used in conjunction with "start" and "count".
3126 SRW support for yaz-client. Use scheme http: to use it, e.g.
3129 yaz-client no longer does (un)intelligent character set conversions
3130 by default. Can be enabled with charset and marc_charset commands.
3132 xmalloc trace fix for 64-bit systems such as DEC alpha.
3134 Solaris 2.6 compile fix.
3136 New function, cql_strerror() translates SRW error codes, as returned
3137 by cql_transform_error(), into human-readable English strings. Used
3138 in yaz-client diagnostics when appropriate.
3140 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3141 converts it into a type-1 query which is sent to the server. This
3142 makes CQL available for use with all Z-servers, as opposed to the tiny
3143 minority that can handle CQL queries themselves.
3145 --- 2.0.2 2003/04/28
3147 New Debian package layout similar to the Redhat Package layout.
3149 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3150 and search result respectively.
3152 --- 2.0.1 2003/04/25
3154 Redhat package is now several packages: libyaz (runtime libraries),
3155 libyaz-devel (development and documentation, and yaz (utility programs).
3156 Package spec file by Morten Bogeskov.
3158 New member 'schema' in struct bend_fetch_rr which the name of requested
3159 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3160 handler MAY set this to reflect the schema of the returned record.
3162 New member 'display_term' in struct scan_entry. GFS now sets member entries
3163 and allocates scan entries to be filled by user scan handler. In previous
3164 version, entries member was allocated by the scan handler. That still works,
3165 but the GFS will ignore member display_term - assuming it was NOT set by
3166 the handler. The fact that the GFS now allocates the entries both allows
3167 for new members and makes a scan handler easier to write.
3169 Fix CQL lex buffer overflow.
3171 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3172 SRU default recordPacking is string.
3174 SRU protocol support for frontend server.
3176 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3178 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3180 Added scan for the ZOOM shell (zoomsh).
3184 * String Identifers for Schemas (Amendment 5).
3185 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3186 Old definition for schema
3187 Odr_oid *schema; /* OPT */
3192 Z_InternationalString *uri;
3193 #define Z_Schema_oid 1
3194 #define Z_Schema_uri 2
3197 * resultCount parameter to Sort Response (Amendment 1).
3198 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3200 Support for SRW 1.0 over HTTP. This is an optional feature and
3201 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3204 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3205 on the same port. SRW SearchRetrieveRequests are mapped
3206 to bend_init,bend_search,bend_fetch,bend_close.
3208 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3210 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3211 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3213 ZOOM connections are SRW based if schem http is used for hostname
3214 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3215 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3217 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3218 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3219 distance=n, order=true/false, relation=le, prox unit=word. If
3220 n is omitted, distance 1 is used.
3222 Fixed problem with C compiler include path in wrong order.
3224 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3225 on Solaris. Patch from Ko van der Sloot.
3227 New MARC decode API. All new functions operate on a yaz_marc_t
3228 handle. The most important new functions are: yaz_marc_create,
3229 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3230 decode and destroy respectively. Decoder can produce formats
3231 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3232 include/yaz/marcdisp.h.
3234 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3235 to UTF-8, UCS-32, wchar_t or Latin-1.
3237 * Prototypes for yaz_iconv_-functions moved to separate header
3238 include/yaz/yaz-iconv.h.
3240 Make a few private functions 'static' in unix.c. This prevents
3241 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3243 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3244 are set when Init Response is received.
3246 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3247 but returns diagnostic set as well.
3249 New function yaz_strerror which is a portable wrapper for
3250 strerror/strerror_r/GetLastMessage.
3252 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3253 is returned for MARC. If type is "oai", then OAI MARC is returned.
3255 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3258 --- 1.9.2 2002/11/26
3260 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3262 Fix bad race conditions on SIGTERM and terminate gracefully in
3265 Move retrieval (data1) module to Zebra since nobody seems to be
3268 Add GRS-1 render for ZOOM using same format as yaz-client.
3270 --- 1.9.1 2002/10/05
3272 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3274 Fix broken ESpec handling in data1 module.
3276 SGML reader parses comments and makes them part of the data1 tree.
3278 Added several type casts so that YAZ compiles as C++ code.
3280 ZOOM didn't handle PDU encoding failures properly.
3282 Added more Bib-1 diagnostics (approved extensions).
3284 GNU configure: better check for iconv.
3286 More portable use of accept, getpeername. Check for socklen_t. Use
3287 int/size_t if socklen_t is not defined.
3291 PQF parser rejects bad queries - including those with extra
3292 characters in them. PQF parser used to silently ignore that.
3293 Cleaner API for PQF added, which allows you to get detailed
3294 error information for bad queries (see yaz/pquery.h).
3296 Fixed bug in ZOOM_record_get for type "database".
3298 Implemented mini iconv library supporting conversions between
3299 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3301 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3303 --- 1.8.9 2002/08/20
3305 Fixed ZOOM C record cache so that preferredRecordSyntax and
3306 elementSetName is used to check for already fetched records.
3308 --- 1.8.8 2002/08/02
3310 Added three members in bend_initrequest structure to facilitate
3311 character set negotiation.
3313 Fixed a bug in frontend server that could cause indefinite
3314 loops under rare conditions.
3316 Revised character set utilities (charneg.h) so that encoding
3317 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3319 For PQF, directive @term <type> sets term type for Scan/Search.
3320 Here <type> is general, string, numeric, null. The term type
3321 is inherited - just like @attr.
3323 New call odr_set_charset that sets character set conversion for
3324 international-strings on a ODR stream. Prototype is:
3325 int odr_set_charset(ODR o, const char *to, const char *from);
3326 The InternationalString is still represented as C string in YAZ
3327 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3328 won't). On the protocol level, you can use any encoding.
3330 Support for UNIX sockets in ZOOM.
3332 Solaris recv sometimes returns errno == ENOENT. It is treated as
3333 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3335 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3336 both client and server. Code by Morten Bogeskov.
3338 --- 1.8.7 2002/05/22
3340 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3341 that they can be used directly from Visual Basic. You must recompile
3342 your windows APP if you're using ZOOM.
3344 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3345 Commands "lang" and "charset" sets language and character set respectively.
3346 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3347 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3349 Attributes from multiple CCL fields may be OR'ed rather than merged
3350 using directive "@field or". Fields are still merged by default -
3351 equivalent to "@field merge".
3353 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3356 Fixed bug in zget for parameter ExtendedServicesResponse.
3360 --- 1.8.6 2002/03/25
3362 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3364 Client displays USR.1:SearchResult-1 (hits per term).
3366 Additional Search Info for search in Generic Frontend Server.
3368 Fixed CCL parsing of "field=s".
3370 WIN32 installer - using the excellent NSIS software from nullsoft.
3372 Fixed CCL parsing of "field = - <number>".
3374 Added function yaz_marc_decode that decodes MARC for line mode
3375 display or XML (similar to that used by JZKit).
3377 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3378 Z39.50. But ISO/ILL was, however.
3380 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3381 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3383 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3384 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3386 --- 1.8.5 2002/02/03
3388 New YAZ client features: Command completion and new commands:
3389 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3390 Code provided by Jacob Poulsen.
3392 New call oid_trav, that visits all registered OIDs via callback.
3394 Function ZOOM_record_get now returns const char pointer rather than
3395 void pointer. It saves a lot of type casts.
3397 For YAZ client, command "auth" now allows you to set authentication
3398 in IdPass style. It is enabled when three tokens are given - order
3399 is user, group and password.
3401 Fix memory leaks in MARC record handling for ZOOM.
3403 New option for YAZ client, -k <kilobytes> that sets
3404 maximum record size. Similar to -k option for generic frontend
3405 server and yaz-ztest.
3407 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3409 Prefix query parser reports "fail" when bad attribute set is given.
3411 Fix in MARC decoder. Proximity logging. Fix for attribute set
3412 in scan handler for server. Patches by Shigeru Ishida.
3414 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3417 Configure option --with-openssl=<dir> now works when a directory is
3418 specified. Patch provided by Morten Bogeskov.
3420 New option for YAZ client, -u <auth>, that sets authentication.
3422 ZOOM fix: error information was sometimes "missing", since error
3423 was cleared/reset too when it shouldn't.
3425 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3427 --- 1.8.4 2002/01/04
3429 Scan for ZOOM API. New object ZOOM_scanset. New functions
3430 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3431 ZOOM_scanset_destroy.
3433 New ZOOM function, ZOOM_connection_last_event, that returns type
3434 of last event (such as "receive data", "send data", "apdu received",
3437 New ZOOM option, schema, that specifies schema for retrieval.
3439 New CCL feature. Qualifiers can be aliases for one or more
3440 other qualifiers (if more than one is given, OR is used).
3442 ZOOM uses named result sets if target supports it.
3444 Two new YAZ client commands: . (dot, which sources a script of YAZ
3445 client commands), and ! (to execute shell command.). Implemented
3448 Working on Debian packages.
3450 --- 1.8.3 2001/11/19
3452 YAZ client enables named result sets only if target supports it.
3454 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3456 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3457 with key="host" to get same result.
3459 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3460 Function Z3950_resultset_record(s) returns references to records
3461 "owned" by resultset. To become owner use Z3950_record_clone.
3463 Function z_ext_record handles Extended Services. Thanks to
3466 --- 1.8.2 2001/11/12
3468 CCL Parser fix: ignore token comma when dealing with and-lists.
3470 Documentation updates for COMSTACK.
3472 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3473 Changed prototype Z3950_records. For some functions, int parameters
3474 were changed to size_t.
3476 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3479 New MARC decode/display function, marc_display_exl, which properly rejects
3480 non-ISO2709 records. YAZ client uses it.
3482 --- 1.8.1 2001/10/29
3484 Fix bug: local attribute set wasn't set correctly in PQF strings.
3488 * Old Z39.50 codecs no longer supported.
3490 Added ZOOM C binding. See http://zoom.z3950.org/
3492 Renamed states for COMSTACKs to avoid confusion with events.
3494 Implemented cs_look and proper cs_rcvconnect.
3496 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3498 Configure detects POSIX threads on OpenBSD.
3500 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3501 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3503 When error is returned from present handler, non-surrogate diagnostic
3504 is returned in present response (and fetch handler is no longer called).
3506 * Minor adjustments to pquery parser (PQF). Token characters may be
3507 escaped by using backslash (C-style).
3509 PQF parser allows string attribute values to be specified. For @attr,
3510 non-numeric characters after the equal-sign are treated as strings
3511 (e.g. @attr 9=title).
3513 CCL trunction character may be defined (@truncation in file)
3515 * function zget_ExtendedServicesRequest sets waitAction to
3516 waitIfPossible (was wait).
3518 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3521 CCL operator names may be set in field definition files (CCL_bibset).
3522 See ccl/bib1 for an example.
3524 Fixes in ASN.1 compiler for C++ compatibility.
3526 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3527 and "op_or" to avoid conflict with C++.
3529 Fixed problem with GNU readline detection on Redhat 7.0.
3531 Added step-size for Scan backend handler.
3533 Fixed bug that made the frontend server crash when no attribute
3534 set was specified for scan.
3536 Front-end server automatically switches to original working directory
3537 when installed as an NT service. Previously -w had to be specified to
3540 Added extended attributes for retrieval module (data1), so that data1
3541 records carry d1_readXML/SGML attributes. d1_read also supports
3542 null-data rules ( <tag/>)
3544 On UNIX when POSIX threads are available, a separate library libyazthread
3545 is created. Programmers should link with that library and the yaz library
3546 when using threads. The reason for the split was that some applications
3547 on Linux, such as Apache, doesn't work well when using shared objects that
3550 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3551 (or any frontend server) in SSL mode by specifying ssl: followed by
3552 address. Only tested on UNIX.
3554 Added feature for CCL module. Virtual structure s=al or s=ol generates
3555 and-list and or-list respectively instead of phrase search.
3559 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3560 log_mask_str. This was done to avoid name conflicts with other libraries
3561 (such as other PHP extensions).
3563 Added raw OID member for preferred record syntax (request_format_raw)
3564 and returned record syntax (output_format_raw) for backend fetch method.
3566 Config file yaz-config now accepts options so that it returns specific
3567 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3569 Shared library support for UNIX using GNU libtool.
3571 * Modified backend interface. Request/Response struct's replaced by
3572 one read/write C struct. For example bend_fetchrequest and
3573 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3574 Every handler - even search has to be registered in bend_init
3575 handler. This means that the YAZ library no longer refers to
3576 external functions and it makes it possible to make the whole
3577 thing a single DLL/SO.
3579 Added Segment handler for backend server.
3581 Added Zmbol/Zebra administrative functions to YAZ client.
3583 Threaded frontend server on UNIX (when POSIX Threads are available).
3584 Starting the server with option -T enables multi-threading.
3588 Added configure option --enable-comp/disable-comp to control use
3589 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3590 located in sub directory asn.
3592 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3593 in ${exec_prefix}/bin along with the other programs yaz-client and
3596 GNU automake used to maintain makefiles.
3598 Added several OID's.
3600 Changed retrieval module so that we can load records with no abstract
3601 syntax defined. Tagpaths in these records are fully composed of string
3604 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3608 On UNIX, the generated makefile now supports a proper 'make install'.
3609 The prefix can be set via GNU configure to set the install location
3610 (default is /usr/local).
3612 * YAZ programs client and ztest were renamed to yaz-client and
3613 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3614 locations, such as /usr/bin,/usr/local/bin,etc.
3616 * YAZ Header files were moved from include to include/yaz. YAZ Header
3617 files are referred to as include <yaz/log.h> rather than <log.h>.
3618 The YAZ include path (-I ..) is therefore the same as before. Programmers
3619 should update their #include statements or use -Ipath/include/yaz
3620 instead. The main motivation for doing this change is that YAZ header files
3621 can be installed in "standard" locations /usr/include,/usr/local/include
3622 without introducing conflicts, since ALL YAZ header files are stored
3623 in subdirectory yaz (under /usr/include for example).
3625 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3626 rather than project/workspace files. We switched because project files
3627 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3630 Changed name of logging function, logf, to yaz_log, to prevent name
3631 clash with some math-log functions. The YAZ header log.h defines logf
3632 to yaz_log (#define) so there should be no incompatibilities by this
3635 Added bend_start/bend_stop handlers for server. These handler are
3636 called on start/stop of server. For windows they are called whenever
3637 a service is started/stopped.
3639 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3640 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3641 in util/yc.tcl. The auto-generated C code structures are, in a few
3642 cases, incompatible with the old decoders. There are differences in the
3643 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3644 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3645 The preprocessor variable ASN_COMPILED is defined when the compiled
3646 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3647 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3648 wish to use the old encoders/decoders you can specify --disable-yc
3651 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3652 version so that it supports both new - and old version of DB Update
3654 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3655 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3656 change. The name parameter can be set to 0 in which no name is specified
3657 for the construction. The macros odr_implicit and odr_explicit sets name
3658 parameter to zero for the construction involved. New macros
3659 odr_implicit_tag and odr_explicit_tag are similar to the others,
3660 except that a name parameter is added. For programmers' that don't use
3661 ODR they probably only need to change the call to z_APDU and z_External.
3663 Added access control facility by interfacing the TCP wrapper library.
3664 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3665 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3666 name of the daemon and enables the access control as specified in
3667 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3669 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3670 den Dool <H.M.vdnDool@kub.nl>.
3672 Added reference ID parameter to most functions in server API - refer
3673 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3675 Changed name of ccl library to libccl.a (was ccl.a).
3677 Fixed bug in decoder for Explain (Category TargetInfo).
3679 Added support for GNU readline in client. Thanks to Jacob Poulsen
3680 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3682 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3683 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3684 IMPLEMENTATION! This change was made to the development version before
3685 the ZIG decided to retract the amendment. If any users MUST be
3686 compatible with the original Update definition, PLEASE CONTACT US, and
3687 we will include a separate definition corresponding to the old Update
3688 ES. Note that because of the change to the ASN.1 of the
3689 TaskPackageRecordStructure we cannot define a single structure that
3690 will support both versions.
3692 * Added const modifier to buffer parameter for some ODR/BER encoding
3693 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3694 completeWAIS, odr_dumpBER.
3696 Fixed bug in client.c which caused a crash when a scanResponse didn't
3697 contain positionOfTerm.
3699 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3700 * will cause an error in a client if a non-YAZ target sends both a
3701 * list of Scan entries and non-surrogate diagnostics.
3703 Retrieval module enhancements. Tag sets may be typed in the reference
3704 to it. From the .abs-file the "tagset" directive takes a third optional
3705 integer type for the tag set referenced. From a .tag-file the "include"
3706 directive takes a third optional type as well. The old "type" directive
3707 in the tag set itself is still recognized but acts as the default type
3710 Backend interface change. Individual Scan terms returned from bend_scan
3711 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3712 in include/backend.h.
3714 Retrieval module enhancements. Multiple tag sets and attribute sets may
3715 be specified in abstract syntax specs. Revised the error/warning for
3716 logging messages reported by the retrieval module when reading the
3719 Object Identifier system (oid_..) changed. The API is backwards
3720 compatible but the oid-routines now allocates new OID's when needed.
3721 Raw OID's may be specified in oid_getvalbyname.
3723 YAZ now uses GNU configure to generate Makefile(s).
3725 * Minor changes in some of the member names of DeleteResultSetRequest and
3726 DeleteResultSetResponse. See include/proto.h.
3728 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3729 and added member 'languages' in TargetInfo (which was missing).
3731 Changed the way attribute sets are handled in the retrieval
3732 module. These are now cached, just like the abstract syntaxes
3735 Changed YAZ so that it links with compiled ASN.1.
3737 Added Explain-schema definitions and mapping routines. The following
3738 Explain categories have been implemented: AttributeDetails,
3739 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3741 Fixed minor bug in Windows version of Server Library.
3743 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3745 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3747 Added EXTERNAL: UNIverse Resource Report (non-standard).
3749 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3750 ENUMERATED and SET OF.
3752 * Added 'const' to some of the char pointer arguments for the
3753 functions, data1_read_node, data1_getelementbytagname,
3754 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3757 Fixed bug in data1_insert_taggeddata - the last_child member of
3758 parent wasn't initialised.
3760 * Changed data1_read_record and data1_read_node so that the supplied
3761 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3762 doesn't refer to any parts of the "SGML"-buffer.
3764 Fixed bug in server library (Windows version of statserv_remove).
3766 * Changed code so that it compiles as C++. The type definition
3767 of Odr_fun which is a member of Odr_arm was changed. The result is,
3768 that an explicit typecast is needed for the fun pointer when
3769 using Odr_arm - as in:
3770 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3772 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3774 Implemented the new structured date and time definition as approved
3775 by the ZIG. Added schemaId element to the specificTag in Espec-1
3776 (also approved at the last ZIG). Thanks to RVDM.
3778 Added some Object identifiers (RVDM).
3780 Changed the Update Extended Service (RVDM).
3782 Added command "refid" to client which specifies referenceId for
3783 the following requests.
3785 Implemented extended service handling for server. See ztest.c
3786 for an example as well as backend.h. New handlers are registerd
3787 in the Init handler.
3789 * Changed interface for sort in server.
3791 Added new members to statserv_options_block. It allows a server
3792 to read options from another source than just the command line. Thanks
3793 to Charles Woodfield.
3795 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3796 renamed to zboolean. Some C++ compilers complained about the name.
3798 Minor changes to gils.abs. Added index 's' (sort) on title
3799 and date/time-last-modified.
3801 --- 1.4pl2 1998/1/30
3803 Fixed bug in server library regarding inetd mode (-i). This bug
3804 was introduced by release 1.4.
3806 --- 1.4pl1 1998/1/29
3808 Added sort facility in client and backend server interface.
3810 Fixed problem with dependencies in Makefile(s).
3812 Fixed bugs for encoders/decoders of extended services and
3815 Implemented sub-tree feature for schemas. Sub-trees are
3816 referenced in *.abs-files. See explain.abs for an example
3817 of the use of this feature.
3819 Modified bib1.att; local attributes for ANY didn't include
3820 ANY itself (only affects use of the retrieval module).
3822 Fixed bug in plain SGML reader in function data1_read_node:
3823 tags with prefix "var" was incorrectly interpreted as variants.
3825 Added feature "sub-schemas" to enable references to - and definitions
3826 of - group of elements.
3828 * Removed member parent from type data1_element (in data1.h).
3830 Implemented function odr_nullval() that returns the value of
3833 * Removed member num_children from data1_node (in data1.h).
3835 Made NT service interface part of the server library. The
3836 function statserv_main uses the NT service when required and
3837 calls the statserv_start / statserv_close routines.
3839 Routine zget_SearchRequest and zget_PresentRequest fills
3840 resultSetName/Id member with "default" instead of "Default".
3842 Fixed memory leak in server. Request queue member wasn't freed.
3844 Fixed nmem_exit so that memory is freed.
3848 Revised the CCL parser utility to be thread safe.
3850 Added function, oid_ent_to_oid, to replace the function
3851 oid_getoidbyent, which is not thread safe.
3853 * Added nmem_init and nmem_exit to initialize and release
3854 NMEM resources. Function nmem_init should be called once in the
3855 initial thread before NMEM/ODR is used. statserv.c and client.c
3856 have been changed accordingly. The change was necessary to make
3857 NMEM thread safe. The NMEM memory pool is shared amongst threads
3858 in a process. Unix-based applications will still work fine without
3861 Added NT Services interface for the the Z39.50 (statserv) Server.
3862 Refer to the ztest.c source on the usage.
3864 Windows 95/NT port using MSVC5.0. Project files are included in the
3867 * Defined new 'global' handle for the retrieval (data1) system. The
3868 new handled, data1_handle, describes the state of the data1 system.
3869 This handle is passed as first argument to virtually all
3870 data1 related routines. The functions data1_create and data1_destroy
3871 creates and destroys a data1 handle respectively.
3873 Added ODR encode stream member to all backend request structures
3874 init, search, scan etc. This stream should be used to allocate all
3875 memory used for the response when thread safe operation is needed.
3877 Changed the comstack utility, cs_addstr, to be thread safe. The
3878 returned hostname string returned by the function is now part the
3881 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3882 function. The cs_straddr takes a COMSTACK handle as argument, so this
3883 function must be used after cs_create and before bind/connect.
3884 This function is thread safe.
3886 Moved test server to 'ztest' directory - generic server code still
3887 in 'server' directory.
3889 Made prefix query (pquery.c) utility thread safe.
3891 Added new function modifier YAZ_EXPORT to 'export' public DLL
3892 functions when using windows (see include/yconfig.h).
3894 Added definitions to the OID database (util/oid.c) (RVDM).
3896 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3898 Added call to ccl_rpn_delete in client program.
3900 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3901 release of RPN structure.
3903 Added support for C++, headers uses extern "C" for public definitions.
3904 With input from RVDM.
3906 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3907 Thanks to Ronald van der Meer (RVDM).
3909 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3911 Added support for private extensions to the OID database
3912 (oid_setprivateoids()). Thanks to RVDM.
3914 Added optional, physical ANY (key replication)
3916 Fixed null-reference problem in GRS-1 output filter.
3918 Proximity operator added to Prefix Query Format (PQF).
3920 In test client command "base" accepts multiple databases.
3922 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3926 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3928 Smallish bug-fixes in the new encoders/decoders (explain).
3930 Bug fixed in DeleteRequest.
3932 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3934 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3936 Added SOIF syntax (using private OID for now) to retrieval module and client.
3938 Added Update extended service.
3940 Added SearchResult-1 additional info structure.
3942 Added optional CCL (ISO8777) interpreter as separate module. Available
3945 --- 1.2 1996/6/10 (1st anniversary release)
3947 Added Summary record syntax. Lightly tested.
3949 Added OPAC record syntax. Untested.
3951 Added ResourceReport service encoders/decoders. Untested.
3953 Fixed bug in z_Unit - wrong tagging on unitSystem.
3955 Fixed bug in the DiagRecs decoder.
3957 Added options for max PDU size and session timeout to frontend-server.
3959 Added documentation of query-language parsers and other supporting utilities.
3961 [frontend-server] Added Attribute set to the bend_scanrequest API.
3963 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3964 surrogate diagnostics were generated.
3966 [retrieval] Allow multiple local values for attribute.
3968 [retrieval] Allow multiple attributes per element in .abs files. index type.
3970 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3972 --- 1.1pl2 1996/4/10
3974 Minor changes, mostly specific to Zebra's requirements (retrieval)
3978 Repaired bug in frontend server when running multiple listening
3979 endpoints in dynamic mode.
3981 z_External() now won't break if a known, ASN.1 value comes encapsulated
3982 in an octet-string. The value will pass through unmodified in an Odr_oct.
3984 Added a bit of code to the demo client to decode & display
3985 ASN.1-structured records represented in the octet-aligned branch of
3986 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3988 Added z_ext_getentbyref() to the ASN module. Doc updated.
3990 * Completed the SCAN definition in the ASN module. This may break SCAN
3991 code based on older YAZ-versions at compile-time. The fix is easy -
3994 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3995 under the SCAN definition. Remember to initialize this, server-people.
3997 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3998 that this does not extend to ODR and ASN.
4000 Comstack allows insertion of established socket (primarily for
4001 inetd-operation of servers). Doc updated.
4003 Front-end server can now start from the inetd in TCP mode. Doc
4006 --- 1.0pl4 1996/1/24
4010 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4011 the rank and record number.
4013 Adjustments to the frontend server.
4015 Fixed diagnostic BER dumper. It ignored the file argument.
4019 Various changes to retrieval module.
4021 Changed the union discriminators of the protocol files from enums to
4022 ints paired with #defines.
4024 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4027 *Changed operator in the RPN structure to 'roperator', again to avoid a
4030 Fixed problems in Explain decoders/encoders.
4032 --- 1.0pl2 1995/12/6
4034 Memory bug in log module fixed.
4036 --- 1.0pl1 1995/12/5
4038 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4040 Bug in Explain DatabaseInfo module fixed.
4042 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4046 The shift to v1.0 signals that we now consider the *core* functionality
4047 of YAZ reasonably stable (the core being more or less equivalent to
4048 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4049 tested (Explain not at all - though that will happen soonish).
4051 Minor changes to code to support Windows port.
4053 Various minor changes after we're getting to use GRS-1 & co. more.
4055 Added Espec-1 format.
4057 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4058 of the protocol and it cannot be selected when encoding (maps into 'string'
4059 when decoding). Needed to talk to some servers.
4061 Demo client can request simple element set names.
4063 Added Diagnostic Format encoders/decoders.
4065 Added simple Close handling to frontend server (no hooks for resource
4066 reporting yet), and demonstration client.
4068 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4070 --- 1.0b3 1995/08/24
4072 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4073 handled incorrectly when records were requested in the searchResponse. This
4074 will only affect you if you use the frontend-server.
4076 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4077 Test-client will ask for and print GRS1. Ztest will return dummy records
4080 Added Explain encoders/decoders to the service-level API. Untested.
4082 Added Extended Services: Item Order encoders and decoders to the Service-
4083 level API. Untested. We could use a recent copy of the pertinent bits
4084 of the ILL protocol to add those bits.
4086 Added diagnostic format 1 encoders/decoders to the service-level API.
4089 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4090 odr_cons.c, which causes a more correct output.
4092 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4093 was always set to 0 when no records were requested in the searchRequest.
4095 * Added better external-handling. This shouldn't harm old code that
4096 *encodes* externals. It can break code that looks for a
4097 'single-ASN1-type' representation, since those types that are known
4098 are now decoded immediately. Look at the SUTRS sample code in
4099 seshigh.c and client.c. Documentation updated.
4101 Handling of structured records in bend_fetchresponse. Length -1 marks
4102 structured record, type is deduced from format field.
4104 --- 1.0b2 1995/06/27
4105 Fairly quick maintenance release to add SUTRS support.
4107 Fixed handling of SUTRS records in the demonstration client.
4109 * Added format field to the bend_fetchrequest and bend_fetchresponce
4110 structures of the backend API (frontend server). When the record is
4111 returned, the value of the format field is mapped to an OID. The
4112 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4113 of the record. The special value VAL_NONE in the bend_request means
4114 that no specific format was requested by the client. Documentation
4115 updated accordingly. Test server (ztest) will return a fixed dummy
4116 SUTRS record if your client requests SUTRS.
4118 Documentation updated accordingly.
4120 You can now set external libraries and RANLIB support in the top-level
4124 First public release.
