3 cql_transform: Use WRBUF for addinfo member
4 rather than a xmalloc'ed one. The primary reason for this is make the
5 system slightly less vulnerable to threading issues. YAZ-756
7 Fix assert in ZOOM when http connect fails YAZ-757
11 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
13 wrbuf_cstr: make it thread safe YAZ-753
15 yaz_log_init_file may take fd=<no> to open log file at the FD given.
19 Offer new utility function zget_AttributeList_use_string.
21 New conversion step, solrmarc, for record conversion module.
25 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
26 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
31 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
32 The standalone ZOOM sort was completely broken since 5.0.13.
34 ZOOM: generate event Connect rather than None for partial connect
35 (in fact getaddrinfo resolving).
37 ZOOM: only supply clientIP for InitRequest. Rather than for all
40 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
42 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
43 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
44 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
46 New "Facets" section in the documentation.
50 Call exsltRegisterAll in yaz_init_globals, so that all applications
51 using YAZ will have EXSLT things enabled.
53 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
55 Update various URLs to the re-organized SRU pages at LoC.
59 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
62 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
63 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
64 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
69 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
73 Fix gcrypt not properly initialized YAZ-740.
77 Describe memcached option for ZOOM.
79 ZOOM: throw present request out of range again YAZ-739
80 Was removed in YAZ 5.0.13.
84 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
85 with localtime_r when threads + fork is used (such as Metaproxy).
87 yaz-config: quote some RHS values (that might include blanks)
89 zoomsh: shows SearchResult-1
91 zoomsh: sortby command
93 zoomsh: use proper list of connections and result sets YAZ-725
95 Avoid yaz_log in sigterm handler for GFS YAZ-737
96 Logging is still performed, but outside sig handler.
98 New ZOOM C feature: result-set caching with memcached. Example:
99 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
101 Remove SSL via OpenSSL support YAZ-732
102 Also deprecate two functions from comstack that aren't working with
103 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
105 Revert "Bison: use %name-prefix directive rather than -p option"
107 --- 5.0.12 2014/01/22
109 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
111 SRU GET/Solr base URLs may hold additional ?args YAZ-729
112 ZOOM option extraArgs already does this, though. It seems useful
113 when dealing with Solr targets to limit by filter, eg.
114 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
116 Remove #fragment for HTTP request encoding YAZ-730
118 Doc: Update list of DLLs/LIBs
120 Doc: update href link to Unix utils and Git.
122 --- 5.0.11 2014/01/15
124 ZOOM: fix "lost connection" problem with servers that uses both squid
125 and another proxy behind it that returns Location headers with relative
128 zoomsh: do not use readline for stdin (no tty) YAZ-724
129 Just use fgets in that case. If the user hits Ctrl-D a new-line
132 zoomsh: empty command ignored YAZ-723
133 rather than performing exit of zoomsh.
135 yaz-url utility offers option -v to enable verbose mode.
137 yaz_url uses yaz_check_location and offers verbose mode.
139 Add new function yaz_check_location.
140 This function gets an absolute URI from Location (HTTP redirect).
142 cookie API: introduce yaz_cookies_reset
144 Update cql.y for newer bison YAZ-720
145 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
146 longer supported. Instead one must use %lex-param and %parse-param .
148 --- 5.0.10 2014/01/09
150 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
153 rpn2solr: support truncation left(2), left&right(3) YAZ-718
155 Mention SRU version 2.0 in yaz-client man page.
159 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
164 Make cs_parse_host public.A
166 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
167 introduced in YAZ 5.0.6.
171 Fix buffer corruption for yaz-ztest record fetch.
175 Allow yaz-ztest to return user-defined records (one record per file).
176 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
178 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
179 Use the stream write instead of odr_printf which has a 4K tmp buffer.
181 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
185 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
186 can read and write this format. For record format JSON, yaz-ztest returns
187 MARC-in-JSON records.
189 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
190 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
194 Improve error reporting for ICU chains YAZ-707
195 Report config element+rule when ICU status is "failure".
197 ZOOM: stop fetching if present response has no records YAZ-710
198 Some targets return less records than their hit count would suggest.
199 This prevents ZOOM from continuing to fetch records if any present
200 response has 0 records in the response.
202 Ensure that GFS calls exit if any listener fails YAZ-710
203 Before, if XML config was in use, it would start the default
208 yaz-ztest: -V shows version (like yaz-client -V)
210 New iconv encoding: danmarc YAZ-692
212 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
214 daemon: only wait for immediate child rather than all children. YAZ-704
216 yaz-client: fix setting of SRU record schema. If scheme was unset, it
217 could lead to invalid memory reference.
221 yaz-ztest returns schema for MARCXML test records. SRU require that
222 recordSchema for records.
224 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
225 instead of non-surrogate diagnostic. This is a per-record failure.
227 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
228 may refer to multiple listeners now. Attribute listenref is a comma separated
231 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
232 option is given for GFS, the dirname of filename (for -f) is used
233 as prefix for options such as cql2rpn, ccl2rpn, etc.
235 Content-Type charset fixes YAZ-701 . Do not inspect charset in
236 Content-Type header for SOAP when decoding SRU. The payload (XML)
237 itself tells what encoding it is. In response, never supply encoding
238 in Content-Type. The response payload (XML) tells what it is (with no
239 encoding in XML it's UTF-8).
241 HTTP decoding: allow blanks in URL paths YAZ-700
245 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
246 and facets. Ensure recordData and recordSchema are always present in
247 record element, because they are required.
249 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
252 Simplify in a lot of places using odr_strdupn.
254 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
258 Increase various buffers in GFS's statserv_options_block
259 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
260 This change makes many type-casts redundant, and, thus simplifies code.
262 Remove last bits of WAIS support.
264 Remove member 'size' from Odr_oct.
266 Slim down the public part of 'struct odr'. Most elements are not part
267 of struct Odr_private.
269 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
270 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
271 In particular facets are supported in both client - and server side.
272 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
273 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
274 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
275 both request/response). This is what a search handler in the GFS
276 will see (regardless of whether operating in SRU mode or Z39.50).
278 Changes to the srw.h (SRU/Solr) definitions include:
279 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
280 (char*), which replace union query and query_type (int). This is because
281 SRU 2.0 supports a queryType parameter. This also means that, to carry
282 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
283 x-pquery=PQFstring (extention parameter). The extension parameter
285 - New element, packing, that has information about SRU
286 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
288 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
290 New element, packing, in Z_SRW_explainRequest.
292 New elements in Z_SRW_scanRequest, queryType and scanClause.
293 These replace query_type and scanClase untion. This is similar to what
296 --- 4.2.69 2013/10/01
298 GFS: log when closing down - at least SIGTERM YAZ-684
299 Also change formatting WRT PID logging a bit.
301 Improve display of MARC records with multi-byte subfield IDs YAZ-695
302 In some rare cases subfield identifiers are multi-byte characters.
303 This will try to deterime length of those and split accordingly.
304 This affects display in line mode as MARCXML/MarcXchange. The encoding
305 of ISO2709 is the same.
307 Change inp argument to const for yaz_read_UTF8_char.
309 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
311 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
313 Better check of marc leader info YAZ-691
314 Problem is that some systems generate MARCXML/MarcXchange with
315 funny headers. These will not work if encoded as ISO2709.
316 Some tests produce new output, due to updated warning messages
318 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
320 yaz-client: display MAB records YAZ-689.
321 Thanks for Heiko Jansen for this patch.
323 New utility z_get_HTTP_Response_server which allows both HTTP server name
324 and HTTP server URL to be given in response.
326 Debian: do not depend on obs tcl8.3.
328 Debian: do not depend on obs libicu36-dev.
330 --- 4.2.68 2013/09/23
332 GFS: pass additionalSearchInfo to search memeber search_input if
333 given. Otherwise pass otherInfo. Request for facets and other search
334 related things will be passed there in future versions of YAZ.
336 New ZOOM setting, authenticationMode, which allows authentication
337 paramters to be encoded in the URL rather than via HTTP Basic auth.
340 rpn2solr: fix nested AND/OR handling. YAZ-685
342 Add comparison routines for some Z-types, such as NamePlusRecord,
343 RPNQuery, Query, RecordComposition and OtherInformation.
345 --- 4.2.67 2013/09/19
347 Don't decode MAB as MARC. Just like we don't attempt to decode
348 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
350 CCL: allow quoted terms for date ranges. YAZ-681
352 Introduce ccl_parser_qual_search. This function makes old function
353 ccl_qual_search, from YAZ 2, available again.
355 Add yaz_facet_list_to_wrbuf. YAZ-683
357 --- 4.2.66 2013/09/11
359 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
360 schema was given for search. YAZ-675
362 Add Solr date range searches. YAZ-621
364 --- 4.2.65 2013/08/22
366 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
368 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
370 ISO2709/MARC parse most octet aligned records; not just those that
371 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
372 MARC parse more records instead of just dumping as is. YAZ-670
374 ZOOM: proper caching for variations of record schema. YAZ-671
376 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
378 --- 4.2.63 2013/07/17
382 --- 4.2.62 2013/07/11
384 New utility z_get_HTTP_Response_details - an extended version of
387 New utility yaz_url_get_error which returns error message of last
388 failed yaz_url_exec call.
390 yaz-url and url functions: allow max HTTP redirects to be controlled.
392 New functions yaz_file_glob2, yaz_xml_include_glob.
393 These functions takes a flags parameter, which, for now only controls
394 whether to fail inclusion of a non-existing file (without glob
395 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
397 --- 4.2.61 2013/06/20
399 For MARC XML parsing, allow record without leader. A fake/default leader
400 is inserted and a warning is tagged with the record.
402 ICU: fix leak in in icu_iter_get_org_info.
404 --- 4.2.60 2013/06/14
406 ICU: fix bug in icu_iter_get_org_info (un-init variable).
408 --- 4.2.59 2013/06/11
410 Implement z_HTTP_header_remove.
412 --- 4.2.58 2013/06/11
414 ICU: Disallow 0 ptrs for some ICU string utilities.
416 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
417 returns original tokens (before normalization).
419 CCL: avoid z39.58/regex truncation when not needed. Apply only the
420 conversion of those masks, when absolutely necessary.
422 CCL: configurable masking character - @mask. Default masking character
425 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
426 full response anyway, so a Transfer-Encoding header will obstruct the
429 --- 4.2.57 2013/05/15
431 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
432 picking a socket. Problem is that some systems has IPV6 support, but
433 we can't create sockets for them, so we pick AF_UNSPEC first.
435 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
436 use content_len to determine resulting Content-Length in HTTP response
437 and NOT Content-Length supplied in headers by user.
439 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
440 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
442 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
445 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
446 with big endian and unsigned char (by default).
448 --- 4.2.56 2013/04/26
450 Fix yaz-client connect (crash in 4.2.55).
452 --- 4.2.55 2013/04/26
454 Fix proxy/host problem for ZOOM that could occur if unix sockets
457 New Debian package libyaz4-dbg.
459 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
460 differently in tcpip_close.
462 --- 4.2.54 2013/04/17
464 Windows installer of YAZ includes YAZ4J as a component.
466 CQL: allow "extra terms" again, by default. Thus, the CQL parser
467 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
468 and earlier. CQL parser may operate in strict mode where queries
469 not conforming to the standard BNF are rejected (syntax error).
470 Whether the CQL parser operates in strict mode is controlled with
471 cql_parser_strict . Strict mode enabled with option -S for utilities
472 cql2pqf and cql2xcql .
474 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
476 --- 4.2.53 2013/04/10
478 New charset, MARC-8c, which is like MARC-8 but allows control characters
479 0x01 through 0x1F, except ESC to be passed through verbatim.
481 Fix a problem with duplicate sub field character in MARC output. Problem
482 happened only when output was MARC-8 encoded.
484 --- 4.2.52 2013/04/03
486 yaz-ztest: Use hash for fake hit count. Before, random number was used.
487 This is problematic for unit tests using yaz-ztest. This patch also makes
488 a hash for CQL queries. For RPN, any term with a leading digit will be
489 treated as pseudu hit count (to force any particular hit count by a client).
491 yaz-ztest: return unique MARC dummy records. Beyond record offset
492 24, the author surname is patched with offset to make all records
495 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
496 on system wide default (/proc/sys/net/ipv6/bindv6only).
497 @4 binds to IPV4 only. @6 binds to IPV6 only.
499 Update CQL API documentation a bit
501 CQL: don't accept extra terms for queries. Makes the CQL parser
502 stricly conformant to the standard.
504 --- 4.2.51 2013/02/12
506 GFS: scan handler gets extra_args from request and may return extra
507 response data . That's for SRU only.
509 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
511 --- 4.2.50 2013/01/30
513 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
515 OPACXML: sync spelling of availabilityDate in XML to that of Schema
516 opaxxml.xsd. The schema had the correct spelling of this member always.
517 The ASN.1 was mis-spelled and still is (API change) - we are
518 not changing this. However, the OPAC to XML conversion had yet
521 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
524 New function, z_ext_record_oid_nmem, which is similar to
525 z_ext_record_oid but takes NMEM rather than ODR
527 --- 4.2.49 2013/01/18
529 ICU: New conversion element 'join' which joins tokens into one
530 with a custom character given by rule attribute.
532 --- 4.2.48 2013/01/10
534 New GFS search member: present_number. This is a hint to the
535 search handler how many records are going to be fetched immediately
536 following search. There's no guarantee that it's going to be the case,
537 since it depends on hit count (for Z39.50 piggyback) and whether errors
540 Make a few functions static (private). The functions getbyte_stream,
541 ungetbyte_stream and yaz_gets are now private. They were never declared
544 yaz-marcdump: exit(5) for serious decoding errors
546 ISO2709 decoding: be more picky WRT header
548 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
549 was only used as to indicate that next-result-set-position should be
551 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
552 Based on patch from Ashley Sanders.
554 Make some functions static/private in PQF parsing. Those functions were
555 never declared in a public header and so should not be in use by
556 applications based on YAZ.
558 --- 4.2.47 2012/11/23
560 ZOOM: special options to control APDU logging.
561 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
562 logging of APDUs until "saveAPDU" option is set again. If logging is
563 already enabled the effect is that current APDU buffer is cleared.
564 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
565 logging (default behavior on new connection).
566 The APDUs sent/received can be obtained by using
567 Using ZOOM_connection_option_get(c, "APDU") or
568 ZOOM_connection_option_getl(c, "APDU", &l).
570 GFS: relay implementation_version from backend
571 From 3.0.40 and later, implementation_version from backend was
572 not used in init response at all.
574 --- 4.2.46 2012/11/15
576 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
577 mode at all. Probably never did.
579 Make a new version of ztest.pem that, at least, is not expired.
581 --- 4.2.45 2012/11/13
583 Fix description of CCL directive 'case'.
585 More tight checking of form arguments (yaz_uri_to_array). Makes
586 YAZ better at rejecting big and/or bad POSTs.
588 SRU decoding does not report more than up to 10 invalid arguments.
590 rpn2cql: less quotes in generated terms. Semantics unchanged, but
591 it's prettier this way.
593 --- 4.2.44 2012/10/25
595 New utility yaz_decode_init_diag. Defined in proto.h.
597 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
598 given for unix local socket.
599 The COMSTACK string for doing so is:
602 unix:/myfile:tcp:localhost:9999/mybase
603 unix:/myfile:localhost:9999/mybase
604 unix:/myfile:http://fakehost/mybase
606 debian: Use dpkg-buildflags in build process.
608 --- 4.2.43 2012/10/19
610 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
611 global's SRU service uses a recordPosition scheme starting from zero.
612 First record's position should be one
613 according to the standard.
615 --- 4.2.42 2012/10/18
617 Allow more namespaces for SRU. This is to allow, for example, an
618 incorrect namespace returned from server
619 http://services.igi-global.com/sru .
621 Minor fixes for compilation on Windows.
623 --- 4.2.41 2012/10/11
625 daemon: log total number of bad signals from child on stop so that it
626 is more easy to spot problems with child worker processes.
628 retrieval: empty backend name attribute omits element set
629 from being used in retrieval.
631 --- 4.2.40 2012/10/04
633 Implement Solr sort strategy "solr", similar to sru11 sorting.
634 This will implement the correct parameters on Solr requst to do
637 --- 4.2.39 2012/09/28
639 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
642 MARC: Extra/missing indicator handled for MARCXML.
643 The indicator length is given in header and is the same for the
644 whole record. If attributes ind1, ind2 are missing, then content
645 character defaults to blank. Extra indicator attributes (beyond)
646 indicator length are treated as an error.
648 Reformat: delete trailing whitespace
650 --- 4.2.38 2012/09/17
652 MARC: fix non-ASCII characters for leader. This is to ensure we can
653 generate XML in UTF-8.
655 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
656 in one node with structure word.
658 --- 4.2.37 2012/09/04
660 yaz-json-parse: JSON output may be pretty printed by using option
663 Increase default value of max message for Z39.50 Init for GFS, ZOOM
664 and yaz-client. Old value was 1 MB. New value is 64 MB.
666 --- 4.2.36 2012/08/22
668 yaz-client: don't display bogus records from SRU servers. Some SRU servers
669 return more records than given by *maximumRecords*. Skipping those in
672 record_render: simplify buffer return handling and fix at least one bad
673 memory reference, that broke the test_embed_record sometimes.
675 Allow http://user:pass@host notation for yaz_url_exec.
677 zoomsh: allow shell command to be executed. Via the system(3) call.
679 yaz_poll: Allow num_fds == 0
681 yaz-client: fix bad encoding of "itemorder item". The itemorder
682 item <no> - command forgot to use length of encoded Item Request
683 package. Error present since YAZ 3.
685 yaz-ztest: fix bad usage of session handle. Bug was introduced when
686 result sets were saved (271a9c83).
688 SRU recordPacking: guess record packing in response rather than looking
689 at the recordPacking element which, OF COURSE, changed semantics in SRU
692 Decode SRU 2.0 responses. The official namespace for responses, according
693 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
694 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
695 nature.com's server, however, usee namespace
696 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
697 we are now using a glob-expr to match up the namespace. ZOOM C and
698 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
699 I can not find a single real example showing the "real" namespace in
700 the documentation from OASIS. The namespace for requests is different
701 from responses, but this is not added to YAZ yet, when we don't encode
704 --- 4.2.35 2012/06/26
706 zoom/record_render: add support for Base64 decoding fo MARC records
707 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
708 which will decode base64 + ISO2709 marc-8 encoded material from text node
711 --- 4.2.34 2012/06/07
713 Add missing definitions ZOOM_resultset_get_facet_field_by_index
714 and ZOOM_resultset_facets_names.
716 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
719 Change APDU dump printing to avoid long leading blanks. For levels 16
720 or larger the level is shown and the indentation is truncated but
721 recursed with modula 8. This makes it still reasonable easy to read
722 - even for nested BER dumps.
724 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
725 return 0 (incomplete package) in case where the BER package was
726 considered too nested (return value of -2).
728 dumpber: lines of level 15 are not indented further. Two spaces per
729 indentation; indentation 15 or more is indented to a fixed indentation
730 and augmented with a level=<no> indication.
732 zoomsh: increase max size of command+args
734 GFS: No limit in RPN buf size in CQL to RPN conversion.
736 --- 4.2.33 2012/05/09
738 New function for daemon utility, yaz_daemon_stop .
740 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
742 --- 4.2.32 2012/04/25
744 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
745 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
747 --- 4.2.31 2012/04/23
749 YAZ daemon utility relays SIGUSR1 to child process.
751 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
752 would result in en empty database list - which in turn would result in
753 encoding failure for search.
755 Fix reading beyond string in yaz_sort_spec.
757 --- 4.2.30 2012/04/11
759 Add two new SRU diagnostics:
760 236: Access to specified database denied
761 1015: Init/AC: Maximum number of simultaneous sessions for Userid
763 Document the very useful ZOOM-C option "apdulog".
765 CQL to RPN: term may be passed through verbatim. This is enabled with
766 truncation.cql . The assumption being that the term is already CQL.
768 --- 4.2.29 2012/03/20
770 record_conv: leader spec may be given for marc element.
771 The leader spec is given as attribute leaderspec for element marc.
772 For example to convert a MARC21 record from MARC-8 to UTF-8:
773 <marc inputformat="marc" outputformat="marc"
774 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
776 record_conv: allow user-XSLT params. For example:
777 <xslt stylesheet="MARC21slim2DC.xsl">
778 <param name="myparameter" value="myvalue"/>
779 <param name="otherparameter" value="othervalue"/>
782 record_conv: fix error handling for missing marc charsets.
784 CQL: fix extra terms in wrong order.
786 --- 4.2.28 2012/03/06
788 record_conv: modify new API for conversion types. The conversion types
789 may be passed in new functions yaz_record_conv_configure_t and
790 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
792 Avoid mixed statement/variable declare; fixes compilation with Visual
795 --- 4.2.27 2012/02/28
797 Add non-standard SRU diagnostic: 235: "Database does not exist".
798 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
799 Update SRU to Bib-1 diagnostic maps accordingly.
801 CCL: add two new diagnostics for unsupported masking. The new
802 diagnostics are: "Embedded truncation not supported" and
803 "Single charcacter mask not supported".
805 --- 4.2.26 2012/02/23
807 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
809 --- 4.2.25 2012/01/11
811 Build YAZ for Ubuntu Oneiric.
813 CCL: allow parantheses for proximity operands. For example CCL query
814 (a) % (b) is now allowed.
816 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
817 marked dead, rather then being destroyed. If not, the session memory is
818 being free'd before the search/scan handler is finished. Also destroy
819 'request' memory in request_release rather than in various places,
820 which resulted in leaks from time to time.
822 --- 4.2.24 2011/12/21
824 cql_sortby_to_sortkeys: honor sort prefix.
826 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
827 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
828 The rpn2cql family of functions now always returns quoted CQL terms.
830 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
832 --- 4.2.23 2011/12/15
834 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
835 sequence is treated as one. For example, &&a=b&&&c& is identical to
838 --- 4.2.22 2011/12/05
840 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
841 APDUs for a connection to a WRBUF.
843 --- 4.2.21 2011/11/23
845 Fix cql_sortby_to_sortkeys. Completely broken before.
847 Make CCL's @truncation work again.
849 --- 4.2.20 2011/11/09
851 New ZOOM connection setting: tproxy. It's like proxy, but does not
852 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
853 to set resolved address + port for a connection outside ZOOM itself.
855 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
857 --- 4.2.19 2011/11/07
859 Fix uninitialized variable in Solr spell support (could cause SEGV
860 for SRU response decoding).
862 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
863 back-end's addinfo through into the ZOOM response addinfo.
865 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
866 they are separated by a colon and a space rather than simply
869 --- 4.2.18 2011/10/28
871 Add support for Solr spell-checking/suggestions through ZOOM.
872 If a Solr target has been configured correctly for spelling-checking
873 and suggestions, these will now be returned on the ResultSet option
874 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
876 --- 4.2.17 2011/09/28
878 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
879 with a flag whether to substitute escape sequences or not.
881 --- 4.2.16 2011/09/22
883 Fix nmem_strsplit_escape to substitute escape char properly.
885 New option for zoomsh -e , which makes it abort on first error and
886 return process exit code to indicate success/failure.
888 YAZ options utility supports special option -- which makes all it treat
889 all following arguments as non-options.
891 --- 4.2.15 2011/09/16
893 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
894 searched if absolute filename is given.
896 Fix conv_xslt() error-reporting when stylesheet is not found.
897 (The value of fullpath is meaningless in this situation.)
899 --- 4.2.14 2011/09/07
901 Fix problem in CQL sort node creation: un-initialized memory.
903 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
904 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
905 CQL sortby depending on whether Type-1 or CQL is actually sent to the
908 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
909 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
911 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
912 will make it possible to use both single-character mask (#) and wildcard (?)
913 in CCL . Throw diagnostic for left truncation because that is not supported
916 --- 4.2.13 2011/09/01
918 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
919 cases using escapes (\-sequences) and masking.
921 PQF parse fix: A trailing backslash followed by end-of-string (\0)
922 would result in a read one byte beyond string.
924 rpn2ccl may use Z39.50 masking for terms (t=z).
926 ICU check fix. Don't include library -lCrun on Solaris, unless present.
928 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
929 not --cppflags (which seeems like an error in icu-config).
931 --- 4.2.12 2011/08/27 RPM package only
933 cql2ccl: fix conversion of terms: operator characters were not
936 --- 4.2.11 2011/08/25 RPM package only
938 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
939 CCL parser will map both # and ? to their regular expression
940 quivalents (. and .*).
942 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
943 of reserved CQL characters.
945 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
946 is, so that they are passed through.
948 --- 4.2.10 2011/08/24
950 ZOOM SRU mode: more aggressive re-connect.
952 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
953 made available as a utility function, declared in <yaz/logrpn.h>
955 rpn2cql_structure() supports proximity nodes (except that the Type-1
956 proximity node's "exclusion" binary is ignored, as there is no way to
957 express that in CQL). Fixes bug #4564.
961 Fix SEGV that could occur if set command of zoomsh was given without
962 value (2nd argument).
964 Fix SEGV that could occur if unsupported transport was given for
965 COMSTACK - say https (when SSL was unavailable).
967 Build yaz-url on Windows too.
971 New utility to get web content. Header is url.h. A command line tool
972 yaz-url is part of the distribution and packages.
974 Fixes for SSL COMSTACK (when gnutls is in use).
976 New functions yaz_base64{encode,decode}. Header is base64.h.
980 ZOOM C includes HTTP response buffer as additional info if it fails
981 to decode the SRU response.
983 Make wrbuf_json_puts available.
987 zoom: throw diagnostic for invalid value for option "sru". Before a
988 bad SRU request was sent.
990 Adding new utility wrbuf_vp_puts.
992 Add cclxmlconfig.obj to win/makefile. It was missing completely.
996 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
997 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
998 redirect was used at the same time.
1000 MARC line mode decoding: be less picky about length given - first
1001 5 digits of header that is.
1003 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1005 Changes to decoding of SRU records: a record with recordPacking=xml is
1006 modified with a new root element <yaz_record> if the recordData contains
1007 multiple children elements. This is to make the record XML parseable
1010 RPN to Solr conversion: encode special characters.
1012 Generic Frontend Server: fix uinitialized member, stepSize.
1014 --- 4.2.4 2011/06/21
1016 Fix a bug in SRU decoding of records.. The database records stored
1017 had un-initialized memory, but it would only be seen with yaz_record_render
1018 and type_spec="ext" .
1020 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1022 --- 4.2.3 2011/06/17
1024 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1026 --- 4.2.2 2011/06/10
1028 Add new utilities to convert from CQL to CCL . These utilities have
1029 prefix cql_to_ccl defined in cql.h.
1031 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1032 lead to memory heap corruptions when ICU utilities were in use.
1034 --- 4.2.1 2011/06/07
1036 Make compilation work without Libxml2.
1038 yaz-client: remove redundant blanks in display of searchResult-1 term
1041 --- 4.2.0 2011/05/18
1043 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1044 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1046 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1047 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1048 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1049 Note that the CQL sortby spec is only converted when the GFS is already
1050 converting from CQL to RPN (cql2rpn element).
1052 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1053 specify whether to collapse delimitors or not. The existing nmem_strsplit
1054 do collapse (collapse parameter = 1).
1056 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1058 Rename internal func yaz_use_attribute_create. While non-static, this
1059 function is not declared in a public header.
1061 --- 4.1.7 2011/03/15
1063 Add -lCrun when linking with ICU on Solaris.
1065 More quicks character set conversions for OPAC records.
1067 --- 4.1.6 2011/03/10
1069 fix problem with record_render: records were converted (character set
1070 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1072 --- 4.1.5 2011/03/08
1074 SRU: add methods for handling DADS SRU-proxy facets.
1076 Separate OPAC record character set for ZOOM_record. yaz_record_render
1077 allows a character set given as charset=from/opacfrom,to where 'from' is
1078 the character set of a bibliographic record, 'opacfrom' is character set
1079 of OPAC record and 'to' is the target character set.
1081 --- 4.1.4 2011/02/21
1083 yaz-client: show may XML format records. Command show followed by 'format'
1084 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1087 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1090 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1092 --- 4.1.3 2011/01/27
1093 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1095 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1096 this package can be distinguished from other vendors.
1098 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1099 as determined by configure
1101 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1103 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1104 returns no error and no record, the present request is considered
1105 partial (only a subset of the records could be returned by backend), and
1106 so it is appropriate to set Present Status to partial-4.
1108 --- 4.1.2 2010/11/02
1110 Move yaz-config man pages to section 1.
1112 More documentation about Solr.
1114 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1115 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1116 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1117 peers on some Linux systems. However, in general that does not work
1118 so YAZ can not rely on that to work. Debian changed behavior in this
1119 respect from Debian lenny to Debian squeeze (still testing as of Oct
1121 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1123 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1125 --- 4.1.1 2010/10/05
1127 Fix yaz-config output: echo_source not set correctly by configure.
1129 --- 4.1.0 2010/10/05
1131 Solr Web Service support for yaz-client and ZOOM.
1133 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1135 --- 4.0.12 2010/08/17
1137 Z39.50 facet support. Facet specifications are passed for search in
1138 other-information with ASN.1 as defined in facet.asn and OID
1139 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1140 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1141 3 is limit (number of entries to get in response). yaz-ztest returns
1142 dummy facets if a client asks for them.
1144 --- 4.0.11 2010/07/09
1146 CCL fixes: bug 2895 and bug 3539.
1148 GR1-display: add comma in display - was removed by mistake in
1151 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1153 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1155 --- 4.0.10 2010/06/18
1157 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1158 result set from a connection. The result set will be on its own
1159 thereafter; no operations on it will perform retrievals from a target.
1160 Only cached copies are returned.
1162 ZOOM C:fix case for HTTP servers responding with Connection:close.
1163 Ensure that if there is a current task it is resumed (like fetching
1164 more records in a result set) . Bug #3484.
1166 PQF parser: use odr_atoi for Odr_int (not atoi)
1168 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1169 values that contain any non-digits are treated as string attributes
1170 (previously decoding only checked for leading character ([0-9]). PQF
1171 encoding: attribute string values are not surrounded by double-quotes.
1173 --- 4.0.9 2010/05/21
1175 New utility for managing threads - thread_create.h.
1177 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1178 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1179 but YAZ' implementation do.
1181 Fixes for yaz_cond-functions on Windows 7.
1183 DLL export more symbols.
1185 zoomsh: show record do NOT render opac.
1187 Remove *.la files from Debian and RPM packages.
1189 --- 4.0.8 2010/05/11
1191 Debian package libyaz-dev depends on libgnutls-dev again (was
1192 removed in YAZ 4.0.6, but due to Libtool it is still needed
1193 even though yaz-config do not list libgnutls libs).
1195 ZOOM: Use only one WRBUF for returning string results for
1196 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1198 ZOOM: ZOOM_connection do not use a shared pointer to
1199 ZOOM_resultset after ZOOM_resultset is destructed by
1200 user. Reverts to YAZ 4.0.4 behavior.
1202 --- 4.0.7 2010/05/04
1204 record-conv: fix problem with at least one XSL conversion -
1205 due to probably incorrect usage of XML XSL documents.
1207 --- 4.0.6 2010/04/29
1209 Fix yaz-config for static mode and the use of SSL (gnutls).
1211 --- 4.0.5 2010/04/29
1213 Forward decl timeval struct in mutex.h and gettimeofday.h.
1215 yaz-config: fix 'static' mode linking.
1217 --- 4.0.4 2010/04/28
1219 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1220 are wrappers for pthreads or Windows. For Windows these are put in
1221 a separate DLL: yaz_cond4.
1223 libyaz.la (whole source) is compiled with thread. If thread support
1224 is enabled enabled, all source of YAZ is compiled with treading support.
1225 This allows core utilities such as yaz_log to use thread facilities.
1226 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1227 thread utilities. This commit moves mutex utilities (mutex.c) from
1228 libyaz_server.la to libyaz.la.
1230 yaz-json-parse displays leading text until error.
1232 --- 4.0.3 2010/04/09
1234 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1235 patch from Giannis Kosmas.
1237 SRU: no longer URL encode SRU database. The URL for an SRU server is
1238 a URL and such is alreeady encoded - at least when given with leading
1239 http:// or https://. This reverts behavior to YAZ 3.0.50.
1241 Support for new MARC XML notation TurboMARC which like MARCXML is a
1242 complete representation of MARC/ISO2709.. This one, however, is more
1243 compact and allows for faster processing with XSLT. TurboMARC can be
1244 used in the marcdisp.h API, from the yaz-marcdump utility and from
1247 yaz-ztest can be configured - via the database - to perform certain
1248 delays when it performs operations search, present and single record
1249 fetch. This allows testers to make yaz-ztest act as a real or even slow
1250 Z39.50 server. Refer to the yaz-ztest man pages for details.
1252 --- 4.0.2 2010/03/09
1254 wrbuf_destroy allows NULL WRBUF passed to it.
1256 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1258 Add ZOOM_connection_close.
1260 No fixed size buffers for ZOOM shell - bug #3257.
1262 tstodr: make it work on s390 platform.
1264 New icu iterator-functions. The new icu_iter-functions makes it possible
1265 to use ICU chains from many threads.
1267 yaz-client: better syntax check for show command.
1269 --- 4.0.1 2010/01/26
1271 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1274 New simple local-file XML include facility which allows file glob-patterns.
1275 Refer to yaz/xml_include.h.
1277 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1280 ZOOM_record_get supports new parameter "format" which makes it format XML
1283 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1284 JSONText in ECMA-262) is JSONValue, not JSONObject.
1286 --- 4.0.0 2010/01/20
1288 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1289 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1291 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1292 POSIX/Unix builds .so with major version 4.
1294 Remove old LOG_-defines from log.h. They have been obsolete and
1295 undefined by default for the last 5 years.
1297 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1299 GFS: Remove socket (int *fd) from search_rr handler. The socket
1300 descriptor ptr is a facility that allowed a search handler to supply
1301 a socket which would serve as a callback - when search was complete.
1302 This facility has now been in use for years.
1304 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1305 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1306 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1307 returns 'const char *' rather than 'char *. The returned string is
1308 read-only and should not be modified by applications. COMSTACK cs_close is
1309 now a void function - it no longer returns int. No applications check for
1310 the value and the implementations has always returned 0.
1312 ZOOM: use size_t for scan hit counts and str size. Functions
1313 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1314 occ (hit count) and len (string length) are now of type size_t pointer
1315 rather than int pointer. This is to be able to represent large hit counts
1316 and to also just to use the proper type for string length (strlen result).
1318 New JSON parser. Refer to include/yaz/json.h .
1320 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1321 Used to be int in some cases. Many wrbuf_-functions used to return an int
1322 indicating some length.. These return values were never used. And so they
1325 ODR: odr_malloc, odr_total now takes size_t for size.
1327 clone_z_type: fix leak; occurred for encoding failures.
1329 --- 3.0.52 2009/12/03
1331 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1332 bug was introduced in 3.0.51.
1334 --- 3.0.51 2009/12/02
1336 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1338 tcpip comstack: fix leak for getaddrinfo.
1340 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1341 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1342 Decoding of SRU "path" database is performed by private function
1343 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1344 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1346 yaz-client: honor base command for SRU. Change when database setting
1347 is applied for SRU and ensure it is kept when a connection is reset.
1348 Change also the way errors are displayed or SRU (decoding of packages).
1350 --- 3.0.50 2009/11/02
1352 Add support for extra request / response data for SRU codecs and GFS.
1353 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1354 for extra data response buffer and length. For the GFS, both request
1355 and response data (XML) is carried in extra_args and extra_response_data
1356 for the search handler. Patch by Ko van der Sloot.
1358 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1359 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1360 10010). This fixes bug #2113.
1362 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1363 cmdfile included a 'quit' command that would result in a memory violation.
1365 --- 3.0.49 2009/10/01
1367 Make a number of functions defined in xmlquery.c static. These have
1368 never been declared in a public header file (yaz/xmlquery.h) and was
1369 made public by mistake.
1371 Improve speed of character conversions (iconv utilities). This makes
1372 conversions from MARC-8 faster.
1374 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1375 unless type desired is "raw". This will prevent type "xml" from
1376 returning ISO2709 .. Which obviously can not be XML parsed.
1378 Fix memory leak in ZOOM that would occur if option apdulog was used
1379 on a re-used connection.
1381 Frontend server logs HTTP requests.
1383 Frontend server now sends Z39.50 close when it times out (sesssion has
1384 been idle for too long). Versions 2.0.30 and earlier also sent close.
1385 But due to a mistake this was disabled in all versions after that, i.e.
1386 the server would just close the socket immediately.
1388 yaz-client emits a better message when receiving an unrecognised
1389 userInformationField.
1391 Skip zero-length subfields when decoding ISO2709. This rare case happens
1392 if a record has two FS characters in a sequence. Without this patch
1393 there would be a reference beyond char array in using_code_len fragments
1396 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1398 --- 3.0.48 2009/08/28
1400 The show command offered by the zoomsh command now takes a 3d optional
1401 parameter type which is what is passed to ZOOM_record. If the type
1402 argument is omitted, "render" is used.
1404 RPN to CQL conv may use USE string attributes (bug #2978).
1406 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1408 --- 3.0.47 2009/07/08
1410 Function yaz_xml2query allows a diagnostic element in the PQF XML
1411 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1412 code and additional info respectively.
1414 The BER BOOLEAN is now the integral type Odr_bool which still happens
1415 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1416 typedef'd to Odr_int. This is still an integral 'int', but it may be
1417 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1418 ASN-1 compiler as well as programs has been updated to use the new types.
1420 --- 3.0.46 2009/06/08
1422 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1423 only the bibliographic record was rendered. For type=opac, an OPAC
1424 record is only returned if it is present.
1426 iconv: small fix for encoding of advancegreek.
1428 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1430 yaz-client: option auto_reconnect=on really reconnects.
1432 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1434 server: avoid null ptr ref for for yaz_poll errors.
1436 build: fix RPM build for RHEL 5.3.
1438 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1440 --- 3.0.45 2009/03/31
1442 Fixed bug #2709: TCP connect returns Invalid argument.
1444 Fixed compilation for mingw.
1446 Honor charset for raw records (ZOOM_record_get).
1448 Fixed use of errno for threaded mode that was seen on Solaris 10.
1450 Fixed argument passing with blanks in value for Windows Service.
1452 Disable YAZ' own log rotate by default (no 1 GB limit).
1453 The variable l_max_size which specifies the log file limit is set to 0
1454 (DISABLED): This is due to the fact that YAZ is most often deployed using
1455 logrotate. Also YAZ can not perform log rotate because of unsufficient
1456 permissions (setuid).
1458 --- 3.0.44 2009/02/17
1460 List supported encodings in man page for yaz-iconv.
1462 Fixed missing SSL libs for --libs output
1464 Re-established OID record syntax application-xml. Nobody should use it
1465 but we don't want to change soname because of this symbol being absent.
1467 --- 3.0.42 2009/02/02
1469 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1471 Added member named_result_sets for init handler struct for the GFS. This
1472 allows a server to disable named result sets.
1474 Removed OID record syntax application-xml.
1476 Added support for rule-based transliterator for ICU wrapper of YAZ.
1478 Fixed bug #1902: yaz-icu XML output.
1480 Make YAZ checks Emacs friendly.
1482 BITSTRING value shows value. Bug #2346.
1484 ISO2709 decoding: skip control characters from indicator data.
1486 Omit sort key by default in yaz-icu's output.
1488 Allow combined single char options (again) for YAZ' options function.
1490 Utility yaz-marcdump got option to display YAZ version (-V).
1492 Allow YAZ to use ICU 3.4.
1494 Added new ICU test case which illustrates removal of diacritics.
1496 --- 3.0.41 2008/12/29
1498 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1500 --- 3.0.40 2008/12/29
1502 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1505 Fixed bug #2352: yaz-marcdump crashes for certain record.
1507 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1509 Added support for Danmarc2 to UTF-8 conversion.
1511 Added support for ISO5426 to UTF-8 conversion.
1513 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1514 implementation version.
1516 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1518 --- 3.0.38 2008/11/10
1520 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1521 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1523 ZOOM C now interprets databaseName option for ZOOM connection as path
1526 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1528 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1530 Dummy Libxml2 types no longer defined in headers of YAZ'.
1532 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1535 --- 3.0.36 2008/09/26
1537 Various ODR chapter fixes.
1539 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1541 Added missing source for Windows compilation, mutex.c.
1543 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1545 For SRU connections in ZOOM all records up to "count" are now fetched.
1547 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1548 in Windows due to bad error handling for Libxml2.
1550 Added facility for sending arbitrary records (ASN.1 any) using
1551 ZOOM C's Extended service update. Patch by Sam Reynolds.
1553 New options for ZOOM C's connection, logapdu which makes ZOOM log
1556 --- 3.0.34 2008/06/18
1558 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1560 --- 3.0.32 2008/06/12
1562 Fixed memory violation that could occur when decoding UTF-8. This bug
1563 was only present in 3.0.30 of YAZ.
1565 --- 3.0.30 2008/06/06
1567 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1568 GNU TLS is used by default (if found).
1570 yaz-ztest returns OPAC records if a client asks for OPAC.
1572 Improved speed of MARC-8 encoding.
1574 Added support for lossy and loss-less MARC-8 encoding.
1576 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1578 Added new Windows Service wrapper (sc).
1580 yaz-client's itemorder command may now send a file.
1582 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1584 Added new function yaz_log_xml_errors.
1586 Allow (but warn) unknown XML attributes in MARCXML parsing.
1588 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1590 The UTF-8 to MARC-8 conversion now uses a different set of characters
1591 for Greek symbols. Bug #2120.
1593 --- 3.0.26 2008/02/21
1595 Added yaz_daemon (daemon.h).
1597 Fixed bug #2068: pkg-config trouble
1599 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1601 --- 3.0.24 2008/01/28
1603 Document --with-xml2 option.
1605 Added OPAC XML XSD (etc/opacxml.xsd).
1607 Allow glob mask for name attribute in retrieval element for the
1608 generic frontend server's retrieval facility.
1610 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1611 except POLLIN/POLLOUT.
1613 Fixed error handling in cs_listen. Bug #2037.
1615 --- 3.0.22 2008/01/20
1617 Fixed version in yaz/yaz-version.h.
1619 Fixed bug #2027: Crash when closing connection.
1621 Changed configure so that ICU support is only enabled if only ICU
1622 and Libxml2 is available (because the ICU chain is XML based).
1624 --- 3.0.20 2008/01/15
1626 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1627 is built. Only this DLL depends on the ICU runtime.
1629 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1630 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1632 Changed license of CCL module to 'Revised BSD'. After consultation with
1633 remaining members of the original EUROPAGATE consortium, we are re-issuing
1634 the CCL module without a separate license. The software was developed by
1635 Index Data as part of a research project. The special license was included
1636 to help feed usage information back to the project consortium to support
1637 project evaluation. At this time, the project consortium has long-since
1638 disbanded, and the majority of the original principals have retired. At the
1639 same time, we have significantly modified the software during the following
1640 years, to the point where very practically no original code remains. To
1641 simplify re-use of the software, we have contacted those members of the
1642 consortium who could be reached, and agreed to re-issue the module as a
1643 proper part of the YAZ package.
1645 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1647 CQL closer to being version 1.2 compliant. CQL also allows free-form
1648 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1651 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1652 bug could make Extended services handling crash in the ZOOM layer. This
1653 bug was only present in YAZ 3.0.18.
1655 --- 3.0.18 2007/12/19
1657 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1660 yaz-marcdump reads and writes collection wrapped records.
1662 Handle OPAC for record conversion module.
1664 Fixes for ICU wrapper.
1666 Allow ICU libs to be controlled with --with-icu .
1668 --- 3.0.16 2007/11/12
1670 Added yaz_poll which is a wrapper for select/poll. When poll is available
1671 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1672 sockets to be in use.
1674 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1675 functionality through an XML based configuration (ICU chain). This system
1676 is useful for search facilities such as Pazpar2 and Zebra that needs to
1677 perform tokenization of indexed material. The ICU code in a separate
1678 library libyaz3_icu.a.
1680 Added HTTP tunnel facility for COMSTACK, bug #1752.
1681 This is a facility that allows a Web proxy, such as squid, to tunnel
1682 Z39.50 traffic. This facility is "transparent" to must applications
1683 using YAZ. It's enabled by using pseudo transport connect: followed by
1684 the proxy address, followed by command, then follwed by he regular
1685 "virtual" addresss. For example,
1686 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1688 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1690 --- 3.0.14 2007/09/21
1692 Fixed bad memory reference in ZOOM_record - cuased by member not being
1693 initialized. This was a problem only in YAZ 3.0.12.
1695 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1696 fields were not removed.
1698 Changed the way C code is generated from codetables.xml. Made a MARC-8
1699 conversion trie for each characterSet section rather than codeTable.
1700 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1701 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1703 --- 3.0.12 2007/09/12
1705 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1706 from ZOOM_record_error).
1708 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1710 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1712 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1714 Better SRW-to-Bib-1 diagnostic mapping.
1716 ZOOM C and yaz-client announces SRU version 1.2 by default.
1718 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1721 Fixed in yaz_sru_decode to allow other version than 1.1.
1723 --- 3.0.10 2007/08/22
1725 Added support for SRU scan for ZOOM.
1727 Added support for the use of the older versions or Extended Service
1728 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1729 set to the version , 1=first, 2=second, 3=third. The third version is
1730 what ZOOM C has used so far. And that, obviously, is the default.
1732 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1733 therefore in Zebra and in SimpleServer-based applications). The new
1734 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1735 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1736 which is passed into the back-end search callback function.
1738 Added support for HTTP Basic authentication in clients: the SRU/W
1739 codec encodes the username/password elements of the PDU structure
1740 appropriately, and these may be set using the "user" and "password"
1741 options in ZOOM-C applications (the same options that are used for
1742 Z39.50 authentication).
1744 --- 3.0.8 2007/06/25
1746 Fixed bug #1208: SSL appears to be broken in ZOOM.
1748 Fixed bug #1206: Libxml2 include path weirdness.
1750 Added oid_name_to_dotstring.
1752 Allow elementSetName to be specified for ZOOM C record update.
1754 Allow waitAction to be specified for ZOOM C based for Extended Services.
1756 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1757 syntax OID. Bug introduced in YAZ 3 series.
1759 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1761 --- 3.0.6 2007/06/06
1763 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1764 directory. yaz-client now reads commands from file given by option -f
1765 if specified; then tries to read .yazclientrc in current directory.
1766 Failing that, it reads .yazclientrc from user's home directory.
1768 Added support for correlationInfo Note and ID for Record Update via
1771 Added yaz-client command querycharset which specifies character set for
1772 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1773 (termListAndStartPoint).
1775 Charset ISO5428:1984 is an alias for ISO5428-1984.
1777 Implemented a way to perform scan in a result set using Z39.50. This
1778 is achieved by attaching the result set name in the characterInfo
1779 (type InternationalString) of OtherInformation in the Scan Request PDU.
1780 The result set is identified in the otherinformation by the new OID:
1781 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1782 This allows for scan in result set and faceted search . Zebra did some
1783 of this in the APT term using attribute type 8 and value being result
1784 set. Using the OtherInformation approach for this is cleaner and easier
1785 to work with in proxies and the like. This facility can be used in
1786 yaz-client using new command setscan which takes a result set as first
1787 argument, start position (APT) as second.
1789 Changed decoding of SRU XML packed records to deal with servers that
1790 have recordData with XML data with multiple root nodes. Also make
1791 comparison for recordPacking case insensitive. Again, one server
1792 returns "XML" where others return "xml".
1794 For SRU responses allow Content-Type application/xml as well as text/xml.
1796 --- 3.0.4 2007/05/21
1798 Fixed bug in character set conversion of BER strings. Bug introduced
1801 --- 3.0.2 2007/05/08
1803 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1805 For OID class, use oid_class consistently.
1807 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1810 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1811 character set for bibliographic information interchange". By Giannis Kosmas.
1813 Added documentation on new OID API.
1815 --- 3.0.0 2007/05/02
1817 Changes to generic frontend server interface: added new member
1818 'query_charset' for bend_initrequest structure. A backend init handler
1819 should set this member to its native character set for query terms.
1820 When defined, the frontend server logic will announce this character set
1821 to a client if the negotiationModel bit is set by the client. All server
1822 implementors are encouraged to specify this. If a backend server does not
1823 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1825 Added CCL utility to remove terms (stop words) from resulting RPN
1826 tree. This is handled by functions with prefix ccl_stop_words_ .
1828 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1829 terms in RPN queries.
1831 Clean-up the CCL API. Moved some internal structures from ccl.h to
1832 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1833 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1834 This is replaced by ccl_parser_find_str which takes a string instead.
1836 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1837 libyaz.la is the core of YAZ except the generic frontend server and
1838 does not depend on POSIX threads anymore. libyaz_server.la is the
1839 generic frontend server facilities and uses POSIX thread functionality
1840 if available. The libyaz.la no longer depends on POSIX threads because
1841 the number of global structures is limited. NMEM no longer re-uses blocks
1842 between threads ; it simply free's memory immediately but allocates in
1843 "large" chunks as usual. We don't expect any performance penalties
1844 because of this. The yaz_log system is still using a global log_level so
1845 caution must be taken when modifying it with yaz_log_init_.. +
1846 yaz_log_mask_str. This, however, should not cause any trouble because
1847 these functions are called during initialization of application code
1848 anyway. `yaz-config --libs server` returns libs for server applications;
1849 `yaz-config --libs` returns libs for non-server applications.
1851 New OID database - with public definitions in oid_db.h. Removed old OID
1852 database including the head oid.h and definitions such as enum oid_value
1853 and struct oident. The new OID database uses the same string names as
1854 before but the 'protocol' is gone. There are now only two representations
1855 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1856 converts from string to OID; functions with prefix yaz_oid_to_string
1857 converts the other way.
1859 Change to emit_term() in CQL-to-PQF query translation: when a term has
1860 the /regexp relation modifier, do not process it for leading and
1861 trailing "^" and "*", which have quite different meanings in regular
1864 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1865 write handlers no longer carries a 'last' parameter. This will make
1866 yaz_iconv flush "less" characters. A flush is performed by call to
1867 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1869 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1870 removed, because function yaz_query_to_wrbuf does the same.
1872 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1873 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1875 Deprecated MARC utility functions removed.
1877 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1880 Branch split: YAZ_2_1_55_branch
1882 --- 2.1.54 2007/03/16
1884 Fix to ZOOM-C so that transparent reconnection is properly handled on
1885 connections that are in asynchronous mode.
1887 Fixed compilation on OpenBSD 4.0.
1889 Large strings in GRS-1 records are now properly displayed in yaz-client.
1891 Added character conversion support for "advancegreek"; based on patch from
1894 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1895 sequence is met. Before the error was not set so it would be unknown.
1897 Adjust yaz-marcdump MARC reader so that it skips until record separator
1900 --- 2.1.52 2007/03/07
1902 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1903 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1904 fd_set structure used as a bitmask for the FDs to be selected on.
1906 Using ACX_PTHREAD macro to check for POSIX threads.
1908 Fixed have-vsnprintf check.
1910 --- 2.1.50 2007/02/23
1912 Fixes for configure on BSD. Bug #900.
1914 Added snprintf/vsnprintf wrappers for systems that don't have
1915 limits (heavens forbid).
1917 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1918 created before all previous tasks were completed and removed from the
1919 task queue, the new task could be removed by a mistake.
1921 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1923 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1925 Fixed bug #832: Problem with MARC/charset in yaz-client.
1927 Fixed bug #668: save command line history for yaz-client.
1929 Fixed bug #830: pkg-config support.
1931 --- 2.1.48 2007/01/23
1933 Extended ZOOM result set options with two options that may be read by
1934 a client: resultSetStatus and presentStatus with values as specified for
1936 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1938 Fixed bug #827: Using SSL fails on Debian etch.
1940 Fixed bug #826: Weird looking chars for set of MARC records.
1942 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1943 that is treated as an ItemOrder with itemRequest being an XML document
1944 external. The value of "doc" is the content.
1946 Extended the GFS search facility. New member of bend_search_rr
1947 'estimated_hit_count' signals that hits is known to be an estmate
1948 (higher or lower than real hit count). New member 'partial_resultset'
1949 signals that the search was partial (hit count is lower or equal than
1950 real hit count). For Z39.50, the information is stored in resultSetStatus
1951 member of SearchResponse APDU. For SRU, the information is signalled
1952 via SRU diagnostic 59: "Result set created with valid partial results
1955 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1957 --- 2.1.46 2007/01/13
1959 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1961 Added ZOOM_connection_peek_event.
1963 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1964 the following new functions:
1965 ZOOM_event_nonblock, ZOOM_connection_process,
1966 ZOOM_connection_get_{socket,mask,timeout},
1967 ZOOM_connection_fire_event_{timeout,socket}.
1968 The existing blocking event handler, ZOOM_event, is a wrapper for the
1969 + blocking ZOOM_event_sys_{poll,select}.
1971 Implemented function ccl_xml_config which parses XML version of CCL
1972 configuration (bug #798).
1974 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1976 Added timings utility (yaz/timing.h)
1978 --- 2.1.44 2007/01/03
1980 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1983 Fixed bug #779: Rotation of apdu.log fails.
1985 Fixed for character set conversions:
1986 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1987 Honor G1 set in MARC-8 decoding.
1989 --- 2.1.42 2006/12/17
1991 Fixed bug #775: char conversion does not handle Alternative UTF-8
1994 Implemented function yaz_marc_read_line which parses MARC line format
1995 records. There is a wealth of formats out there. So far, this function
1996 reads line records produced by yaz_marc_write_line.
1998 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1999 more generic and easier to remember(!) options: -i format and -o format
2000 which specifies input format and output format respectively - where
2001 format is one of "marc", "marcxml", "line", "marcxchange".
2003 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2004 does not print anything except warnings for records.
2006 For yaz-marcdump, added support for MARC split into files (-s) with a given
2009 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2010 spec, at http://www.loc.gov/standards/sru/record-update/
2011 This has changed the binary layout of the following structs:
2012 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2013 bend_update_rr . Patch by Ko van der Sloot.
2015 Added GFS utility function bend_assoc_is_alive which returns 1 if
2016 association is still alive (client is connected); 0 otherwise (client
2017 closed connection). This allows busy servers to stop working for
2020 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2021 been a separate piece of software. This version of ziffy has been modified
2022 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2024 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2026 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2027 Client code may now interrogate options such as "init_opt_sort" to
2028 find out whether the server claims to support various options.
2030 --- 2.1.40 2006/11/27
2032 Added utilities yaz_{set,get}_esn to set/get element set name from
2035 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2036 of YAZ and has been so since YAZ 2.1.10.
2038 Implemented ZOOM_record_error which returns error information for
2039 record (surrogate diagnostic).
2041 --- 2.1.38 2006/10/31
2043 Updates for SRU Update by Ko van der Sloot:
2044 1. Changed name from "operation" to "action"
2045 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2046 versions in the code, marked as 'backward compatible'.
2047 3. Added diagnostics for SRU Update.
2049 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2051 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2053 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2055 For GFS, fixed problem with SRU diagnostic 'First record position out of
2056 range' being issued for 0 hits.
2058 zoomtst10 part of Windows Build.
2060 --- 2.1.36 2006/10/13
2062 Implemented yaz_filepath_comp which splits a path into file path
2063 components (required by Zebra 2.0.3+).
2065 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2066 BSD inspired license until now so this should not have any real impact on
2067 anybody. See http://www.opensource.org/licenses/bsd-license.php
2069 Fixed bug #687: Missing log lines.
2071 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2074 Fixed bug #689: SRU diagnostics to be added.
2076 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2077 whether a connection is idle (no more work do do).
2079 --- 2.1.34 2006/10/04
2081 Change type of optval from long to int for invocation of setsockopt with
2082 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2084 Added support for specifying the max log file size for the Generic
2085 Frontend Server. The size is given with option -r.
2087 --- 2.1.32 2006/09/21
2089 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2091 --- 2.1.30 2006/09/17
2093 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2096 Fixed bug in Generic Frontend Server that could cause a server to stop
2097 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2099 For the generic frontend server, the maximum record size is used as maximum
2100 size of incoming packages (SRU + Z39.50). The value until was previously
2101 only used in Z39.50 Init negotiation and, later, in a session controlled
2102 sizes of records returned. This is controlled using -k option. It can be
2103 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2105 --- 2.1.28 2006/09/04
2107 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2110 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2112 New option for yaz-marcdump -lpos=value which allows setting a portion
2113 of MARC header to a certain value.
2115 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2117 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2118 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2120 --- 2.1.26 2006/08/15
2122 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2125 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2127 --- 2.1.24 2006/08/08
2129 Fixed MARC ISO2709 encoding routines to deal with character set
2132 Minor changes to GFS logging. Database included in search request log
2135 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2136 cached/multiple records.
2138 Shared libraries are built by default on Unix+configure.
2140 Changed cql2pqf transformation to use a different evaluation order. The
2141 new order is: always, relation, structure, position, truncation, index
2142 and relationModifier. Old order was: always, relation, relationModifier,
2143 structure, index, position, truncation. Note that the the latter ones
2144 override former ones for identical attributes.. The new scheme means that
2145 it is possible to override any existing attribute with a relationModifier.
2146 And also that it is possible to override everything for the index rule
2147 (except the ones listed in relationModifier). No order is perfect but this
2148 one, we believe, covers more real cases.. The "always" should have been
2149 called "default", since the attributes there can be overridden with all
2152 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2153 compilation phase, but also for yaz-config --cflags output. This allows
2154 us to have public headers with Libxml2 stuff in them . It should also,
2155 eventually, make Libxml2 checks redundant in packages using YAZ, such
2158 --- 2.1.22 2006/06/15
2160 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2161 stored in uri, message and details.. Previously diagnostics were stored
2162 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2163 compatibility.. but he's probably the only one affected, so.
2165 Added support for CCL, compiled on the client side, in ZOOM-C. This
2166 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2167 input; the resulting query objects can be used for for searching with
2168 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2170 YAZ' configure searches for OpenSSL by default.
2172 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2173 SL_CTX_use_certificate_file. See
2174 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2175 for more info. Thanks to Ko van der Sloot.
2177 --- 2.1.20 2006/06/02
2179 Bug #600: SRU GET, POST support for yaz-client. Introduced
2180 command 'sru' which selects method SOAP/GET/POST.
2182 Allow missingValueAction to be specified for the sortspec string -
2183 function yaz_sort_spec. By default, the missing value action is null.
2184 Use ! to specify "abort". Use = followed by stringvalue to specify default
2187 Ensured that Present-handler (if defined) is called in GFS before any call to
2188 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2189 searchRetrieve requests.
2191 Documentation for YAZ is now based on the Docbook XML/XSLT using
2192 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2193 is no longer depending on jade/openjade or docbook-to-man scripts.
2194 PDF is no longer part of the distribution - but can optionally be
2195 made using DSSSL/jadetex or FOP.
2197 Added retrieval handling support in Generic Frontend Server to support
2198 conversion between MARC/XML as well as XSLTtransforms. See
2199 etc/yazgfs.xml for an example.
2201 Added Authentication support to Generic Frontend Server in SRU
2202 mode. Authentication using HTTP Basic is supported, as is the use
2203 of 'x-username' and 'x-password' parameters in the request itself.
2205 Added support for a new character set MARC8s identical to MARC8 except
2206 that it converts combined characters to single Unicode characters in the
2207 Latin-1 range (when possible).
2209 --- 2.1.18 2006/04/24
2211 ASN.1 compiler 0.4: generates brief Doxygen file header for
2212 generated .h/.c files.
2214 Utility yaz_iconv now supports conversion to MARC-8.
2216 New facilities for the MARC module. The reading - and writing of
2217 content are separate methods for the yaz_marc_t handle. The following
2218 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2219 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2220 format). Write functions have prefix yaz_marc_write_.. The existing
2221 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2222 available. Removed support for OAI-MARC and simplexml (not the
2223 simplexml from PHP5).
2225 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2226 to be returned for this connection.
2228 --- 2.1.16 2006/03/31
2230 Allow multiple languages and charsets to be specified with
2231 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2232 negcharset iso-8859-1,utf-8
2234 Translation of proximity nodes from CQL into PQF now works.
2236 Moved to automake 1.8, 1.9.
2238 Added function yaz_log_set_handler which allows a log handler to be
2239 installed. This handler will be called for all log messages. Output
2240 to file is also produced; but that can be disabled by passing NULL
2241 fname to yaz_log_init_file.
2243 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2245 For SRW (including GFS), accept application/soap+xml as content-type
2248 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2249 produces NO stylesheet reference even if a default stylesheet is specified
2252 --- 2.1.14 2006/03/14
2254 Updated Windows package to include yazd.dll + yazd.lib for the
2255 Development component.
2257 If the environment variable YAZ_LOG is set, then it is used as a
2258 string indicating the default level of logging to use if not
2259 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2260 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2261 used as before. So, for example, to omit warnings from YAZ logging,
2262 export YAZ_LOG=-warn
2264 cql_transform() now map structure and other attributes before indexes,
2265 so that index-specific structures and other attributes can override
2266 defaults. So now a combination of mapping specifications such as:
2268 index.dc.date = 1=date-modified 4=5
2269 does the right thing.
2271 cql_transform() now also respects the "always" mapping specification,
2272 which establishes an initial set of attributes to be used for all
2273 terms except where overridden by more specific attributes associated
2274 with the index, relation or modifier.
2276 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2277 which mode to use; one of "post", "get" or "soap" (SRW, default).
2279 Fixes for yaz_iconv routines: changed trie-based character set conversions
2280 to use only non-negative values for bit fields due to Sun's C compiler not
2281 supporting negative values.
2283 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2284 sequences where not read correctly. Fix by Rustam Usmanov.
2286 Updated win/makefile to use options, settings which makes things
2287 compile with VS C 2005.
2289 --- 2.1.12 2006/02/01
2291 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2293 In ZOOM socket code, use select instead of poll on MacOSX.
2295 ZOOM-C now support client-side compilation of CQL into RPN that is
2296 sent to the server, enabling CQL to be used against all Z39.50
2297 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2298 ZOOM_query object, and submit it using ZOOM_connection_search().
2299 The CQL-to-RPN translation uses a configuration file, the name of
2300 which must be specified in the Connection's "cqlfile" option.
2302 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2303 function, which takes as its start-term parameter a ZOOM_query object
2304 (which may have had either CQL or RPN set into it).
2307 --- 2.1.10 2005/11/29
2309 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2310 GFS to support this as well. Backend handler, bend_srw_update, does the
2311 update work. Code contributed by Ko van der Sloot.
2313 Allow retrieval of Search Result-1 information in ZOOM by the use of
2314 options that are attached to a result set. ZOOM documentation updated
2317 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2318 UTF-8 conversion. Patch by Raj Patel.
2320 Added option -m to GFS to control formatting of timestamps in log file.
2322 Added 'exit' as synonym for 'quit' in yaz-client
2324 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2325 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2326 for the new members. Patch by Ko van der Sloot.
2328 Added support for SRU POST. It is supported for content-type
2329 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2331 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2332 Instead make the library libyaz.la multi-threaded. Threading as a whole
2333 can still be disabled by configure option --disable-threads. Previosly,
2334 with older GLIBCs there were problems with MT libs under Apache. This
2335 has now been fixed a long time ago.
2337 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2340 CQL module modified to be case insensitive for relations/indexes/operations.
2342 Fixed bug in CQL transform code: incorrect value relationModifieder
2345 Added 'show all' command for yaz-client which retrieves all results
2348 Added new yaz-client, xmles, which takes a (private) OID and
2349 a document to be sent as an extended service request.
2351 Describe new yaz-client commands wait_response and set_auto_wait.
2353 Increase TCP/IP listener backlog from 3 (which I am guessing was
2354 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2355 that the socket will queue as many incoming connections as it's able
2356 to handle ongoing connections. In other words, it will never now
2357 refuse a connection that it would be able to handle merely because
2358 it's not got around to accepting() enough of the pending connections
2359 yet. This is the behaviour anyway under Linux, where the listen()
2360 argument is ignored; but not under BSD and on systems such as
2361 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2362 YAZ-based servers should now be uniform across operating systems in
2365 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2366 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2367 This allows yaz-marcdump to read large MARC batches (>2 GB).
2369 Modified all YAZ source files - except the source which is auto-generated
2370 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2373 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2374 corresponding to the existing *_setl() function. These allow option
2375 values containing arbitrary valuues.
2377 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2378 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2379 except that it returns an indicator of whether or not the sort
2380 criterion was accepted (0 for OK, -1 for invalid).
2382 --- 2.1.8 2005/06/07
2384 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2385 MARC output rather than returning "new" buffer.
2387 yaz-client warns about unknown init options.
2389 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2391 --- 2.1.6 2005/05/24
2393 Added support for SRW sort in Generic Frontend Server. Patch
2394 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2395 sortKeys - or NULL if none is provided.
2397 Fixed bug #307: It was impossible to specify indefinite/no timeout
2398 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2401 Added support for multiple languages and charsets to be specified in
2402 ZOOM. Each charset/language is separated by a blank. If negotiation is
2403 in effect in init-response, Option
2404 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2405 Code based on patch by Vasiliy Osadchuk.
2407 Fixed bug #306: infinite recursion that occurred when calling
2408 yaz_log_level_init as the first call (before other log level or
2411 Fixed bug in scan handling in front end server: if preferred-Position-In-
2412 Response was non-present, a NULL pointer referece was performed.
2414 --- 2.1.4 2005/04/26
2416 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2417 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2418 now defined for all those error codes. So instead of putting 109 in
2419 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2420 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2422 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2425 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2427 Program yaz-client now exits and produces an error message if multiple
2428 Z39.50 servers are specified on the command line (none or one allowed
2431 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2434 --- 2.1.2 2005/03/16
2436 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2438 Fixed bug #272: Preserve spacing for CCL terms.
2440 --- 2.1.0 2005/03/14
2442 Added support for virtual hosts and multiple backend servers for
2443 the YAZ frontend server. The configution is XML based and
2444 support specificition of CQL to RPN mappings and explain information.
2445 See section "Virtual Hosts" in the YAZ manual.
2447 Extended OPAC display utility. OPAC display utility renders
2448 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2449 to supplement yaz_marc_decode_wrbuf.
2451 Fixed a bug in MARC decoder that could caused it to crash for some
2452 invalid MARC records. More diagnostics and warnings where added in
2453 XML output (warnings, etc are stored in comments).
2455 --- 2.0.34 2005/02/08
2457 Fixes for UNIX domain sockets. Bug #261.
2459 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2461 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2462 Added yaz_marc_subfield_str which defines subfield lead string which is
2463 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2464 yaz_marc_endline_str which defines end of fields string used in
2465 YAZ_MARC_LINE format. Default string is newline.
2467 Experimental support for MarcXChange. This format can be produced
2468 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2469 http://www.bs.dk/standards/MarcXchange.xsd
2471 Added yaz-client commands scansize that sets maximum number of
2472 entries to be returned by scan.
2474 --- 2.0.32 2005/01/11
2476 Added support for SRW scan in yaz-client and Generic Frontend Server.
2478 * Added whereInList member to SRW Scan Term.
2480 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2482 Fixed NMEM system to return aligned blocks on the smallest boundaries
2483 that are suitably aligned for all possible types on the particular
2484 architecture YAZ is being built for.
2486 --- 2.0.30 2005/01/04
2488 Fixed numerious warnings that was issued with newer versions of GCC.
2490 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2491 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2494 Make YAZ Generic Frontend Server slightly faster.
2496 Enhance (and reduce) logging for Generic Frontend Server.
2498 Revert YAZ log system so that it flushes every write operation
2499 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2501 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2502 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2503 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2504 will effectively disable old definitions.
2506 --- 2.0.28 2004/11/09
2508 Added yaz_log_time_format which specifies log format using
2511 Added yaz_log_module_level which returns mask for a module. Value
2512 is non-zero mask a if module is enabled; zero if disabled.
2514 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2515 in include/yaz/cql.h.
2517 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2519 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2521 Fixed bug #172: RPM builds does not enable SSL.
2523 Doxyfile.in part of dist. Doxyfile generated by configure.
2525 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2526 are given and the corresponding component does not exist.
2528 Extend CCL documentation in YAZ reference. Describe r=r.
2530 --- 2.0.26 2004/10/01
2532 Fixed MARC->MARCXML conversion to properly deal with
2533 fields, subfields, indicators having non-ASCII characters.
2535 Fixed MARC->MARCXML conversion so that ASCII control characters
2536 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2539 Added YAZ GFS support for conversion from Z39.50 surrogate
2540 diagnostics to SRW surrogate diagnostics.
2542 Bug fix: YAZ GFS did not return schema in explainResponse.
2544 --- 2.0.25 2004/09/30
2546 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2547 now converts recordSchema to elementSetName as well as schema URI.
2549 Fixed bug in COMSTACK that prevented HTTP request packages from being
2552 --- 2.0.24 2004/09/29
2554 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2555 does not require white-space before and after the dash in a range, e.g.
2556 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2559 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2560 due to new GCC removing "redundant" code.
2562 Added yaz-client commands scanpos and scanstep that sets preferred
2563 position and step-size for scan.
2565 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2567 Added CCL utility ccl_qual_buf which parses one or more CCL
2568 spec lines in a buffer.
2570 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2571 of name and value - ignoring empty lines and comments.
2573 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2575 Added odr_get_element_path which returns current element path for an
2576 ODR handle. This utility is useful in error handling or user-defined
2579 Added ODR_PRINT utility odr_set_stream which is is a more generic
2580 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2581 to a write function and pointer to close function. The close function - if
2582 non-NULL - will be called during odr_destroy.
2584 Fixed bug in CCL parser where truncation char was not removed from
2585 right side when truncation=both was in effect.
2587 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2590 --- 2.0.23 2004/08/11
2592 Fix buffer overrun in CQL parser when dealing with proximity (%).
2594 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2595 to UTF-8/UCS conversion is now only based on codetables.xml.
2597 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2599 --- 2.0.22 2004/08/06
2601 Add support for more "commit changes" in ZOOM (uses Extended Services).
2603 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2606 Yet another small fix for configure of SSL.
2608 --- 2.0.21 2004/05/14
2610 Fix SSL libs for configure when --with-openssl=DIR is given.
2612 --- 2.0.20 2004/05/10
2614 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2616 SSL comstack now uses yaz.pem certificate file on server side
2617 by default. Certificate filename can be configured by calling
2618 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2620 Fix bug regarding multiple calls to ZOOM_connection_connect.
2622 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2624 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2625 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2627 ZOOM now allows inspection of X509 peer certificate for verification.
2628 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2630 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2631 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2632 as "modular" but it simplifies things.
2634 Added cs_get_peer_certificate to that returns peer X509 PEM.
2636 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2637 NULL if SSL is unavailable.
2639 Documentation about MARC decoding tools.
2641 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2643 --- 2.0.19 2004/03/30
2645 Rename CHANGELOG to NEWS to follow GNU style packing.
2647 Fix bug with missing initialization of member in init_diagnostics.
2648 This bug affects threaded version of GFS server.
2650 --- 2.0.18 2004/03/20
2652 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2655 Ensure zlib.dll is packed with Windows install.
2657 --- 2.0.17 2004/03/17
2659 Fix encoding of xsd:string to use text instead of CDATA.
2661 Fix endless loop in CQL parser with unbalanced ".
2663 Use a more compact way to store MARC-8 conversion tables.
2665 --- 2.0.16 2004/03/16 Debian only
2667 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2670 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2675 --- 2.0.15 2004/03/01
2677 Another fix for decoding of XML packed records.
2679 --- 2.0.14 2004/02/25
2681 Fixes for Chunked encoding. White space not ignored after length spec.
2683 Update NS and use default NS for SRW diagnostic elements.
2685 --- 2.0.13 2004/02/23
2687 Implement ZOOM_resultset_cache_reset which resets record cache.
2689 Implement ZOOM_resultset_sort which sorts a result set.
2691 Implement chunked HTTP transfer.
2693 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2695 --- 2.0.12 2004/02/16
2697 Added member 'schema' to bend_explain_rr structure so that backend
2698 can specify explain record identifier. Defaults to Zeerex 2.0.
2700 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2702 --- 2.0.11 2004/02/16
2704 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2707 Added init command for yaz-client which sends "extra" init request.
2709 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2710 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2712 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2714 Make ZOOM error code for "invalid query".
2716 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2718 --- 2.0.10 2004/02/05
2720 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2723 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2725 Added option -p <file> to make Generic Frontend Server to write PID file.
2727 Added option -D to put Generic Frontend Server in background on its own.
2729 Make ZOOM C recognize option "password". If unset, "pass" is used
2730 (for backwards compatibility).
2732 Fixed a bug in Generic Frontend Server that could make it crash if a
2733 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2736 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2737 Must be issued before open, in order to be in effect.
2739 --- 2.0.9-6 2004/01/12 Debian/Windows
2741 Make the SRU server more picky WRT unknown params, etc.
2743 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2745 New YAZ client command, options, that sets Z39.50 options.
2747 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2748 options from a string of tokens (one token for each option bit).
2750 Update SRW diagnostic code messages.
2752 --- 2.0.9-5 2004/01/07 Debian/Windows
2754 Handle user defined stylesheet for SRW/SRU.
2756 --- 2.0.9-4 2004/01/06 Debian/Windows
2758 Fix bug in decoding of Content-Length.
2760 --- 2.0.9-3 2004/01/06 Debian/Windows
2762 Fix a bug with decoding of XML packed records.
2764 --- 2.0.9-2 2004/01/05 Debian only
2766 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2768 Fix bug in SRW/SRU diagnostics decoding.
2770 --- 2.0.9 2004/01/05
2772 Fixed bug in Generic Frontend Server which could drop records exceeding
2773 preferred message size. Reported and fixed by Irina Dijour.
2775 Fixed calculation of package size for structured records in Generic
2776 Frontend Server. Reported and fixed by Irina Dijour.
2778 Fixed namespace for SRW/SRU diagnostics.
2780 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2782 --- 2.0.8 2003/12/22
2784 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2785 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2788 CQL changes to reflect recent changes to the specification:
2789 * Documentation talks about context sets instead of index sets.
2790 * Documentation talks about indexes instead of qualifiers.
2791 * The CQL-to-PQF transformer's configuration file now uses
2792 "index.set.name = <attributes>" instead of the old form
2793 "qualifier.set.name = <attributes>". (Both forms are still
2794 understood but the latter is deprecated.)
2795 * CQL terms with no explicit index specified are now interpreted as
2796 cql.serverChoice instead of srw.serverChoice (which of course
2797 behaves exactly the same.)
2799 --- 2.0.7 2003/12/16
2801 MARC conversion can now generate ISO2709 output in another
2802 character set. yaz-marcdump uses this facility if you invoke it
2805 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2806 functions from there can be used from C++.
2808 --- 2.0.6 2003/12/04
2810 Frontend server now transfers memory from decoded packages to stream
2813 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2814 references to show up.
2816 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2817 the ZOOM Abstract API. The older names for the same options are still
2818 also supported for the benefit of old applications.
2820 ZOOM-C supports "implementationId" and "implementationVersion" options
2821 to go along with "implementationName". These allow the user code to
2822 specify identification strings to be sent to servers.
2823 Add OID for the new ExtLite attribute set.
2825 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2826 as requested/supplid by Ere Maijala <ere@atp.fi>
2828 For generic frontend server, reverse the order of
2829 "toolkit-supplied / application-supplied" strings sent as implementationId,
2830 Name and Version. Also, remove the spaces around the slash. This brings
2831 the GFS in line with the behaviour of ZOOM-C on the client side.
2833 Add function ZOOM_scanset_display_term.
2835 yaz-client shows scan displayTerm if present.
2837 Utility yaz-iconv is now installed by default along with the man page
2840 Extend configure check for OpenSSL to use pkg-config where available (such
2843 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2844 server to specify uid/gid/mask for socket using the format
2845 unix:[user=uid,][group=gid,][umask=mask,]file=path
2846 If file= is omitted the existing format is assumed, e.g.
2848 in which case the mask is 0666 (rw for everybody).
2850 Major restructure of YAZ source. All source in libyaz is in src directory.
2851 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2852 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2854 Added man page for utility yaz-marcdump (used to be called marcdump).
2855 yaz-marcdump is installed by 'make install'.
2857 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2858 of incoming package failed.
2860 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2862 Change prototype of odr_perror: add const to message string.
2864 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2866 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2867 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2868 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2869 DNS lookup. There should not be any compatibility problems with this
2870 assuming that blocking=1 or 0 is used.
2872 Fix bad reference in UNIX comstack in function cs_addrstr.
2874 Fix for compilation on AIX.
2876 The generic front-end server (server/seshigh.c) now supports returning
2877 Init diagnostics to the client in User-information-field, in
2878 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2881 --- 2.0.4 2003/09/04
2883 Allow any CQL relation (not just all,any,exact,scr).
2885 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2886 that features the same UI.
2888 Implemented command update0 in YAZ client which is equivalent to
2889 update but uses old of Ext Update ASN.1.
2891 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2892 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2893 Previously no OID was used for this info.
2895 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2896 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2897 returns 'malformed search term' otherwise.
2899 SortResponse member resultCount now set to NULL in sort handler of
2902 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2905 Add three new utility functions for translating OIDs between various
2906 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2907 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2908 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2909 char *oid_to_dotstring(const int *oid, char *oidbuf);
2910 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2912 Reverted modifications for ES Update definition for z_IU0Update
2913 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2914 is back to YAZ 2.0.2.
2916 String value attributes for CCL parser.
2918 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2919 which their FirstSearch server returns in Init responses, sometimes
2920 carrying useful diagnostic information when Init fails. This has the
2921 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2922 "z39.50/oclcui.asn", where its definition is somewhat different from
2923 what OCLC document on their web-site, as required to interoperate with
2926 Support for anonymous authentication in yaz-client. Use the command
2929 * Fix the OID of the Index Data-local "admin" Extended Service from
2930 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2931 the 1000, which indicates a locally-defined OID, was a mistake.
2933 --- 2.0.3 2003/06/20
2935 Fix CCL directive @case handling so that it affects string match for
2936 both CCL keywords and qualifiers.
2938 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2939 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2940 Decoder has been updated with ASN.1 changes as listed in
2941 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2942 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2943 z_IUUpdate, remains unchanged.
2945 ZOOM_record_get may now return a record in a specific character set.
2946 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2947 "from" is the character set of record as returned by target. "to" is
2948 the character set to be returned. If omitted, "to" is UTF-8.
2950 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2952 New ODR utility, odr_getelement, which returns name of element for
2953 which encoding/decoding failed.
2955 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2956 in cases where a required element was omitted.
2958 Bug fix: some MARC8 sequences were not converted.
2960 New ZOOM option "step" which specifies number of records to be
2961 retrieved in one chunk. Used in conjunction with "start" and "count".
2963 SRW support for yaz-client. Use scheme http: to use it, e.g.
2966 yaz-client no longer does (un)intelligent character set conversions
2967 by default. Can be enabled with charset and marc_charset commands.
2969 xmalloc trace fix for 64-bit systems such as DEC alpha.
2971 Solaris 2.6 compile fix.
2973 New function, cql_strerror() translates SRW error codes, as returned
2974 by cql_transform_error(), into human-readable English strings. Used
2975 in yaz-client diagnostics when appropriate.
2977 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2978 converts it into a type-1 query which is sent to the server. This
2979 makes CQL available for use with all Z-servers, as opposed to the tiny
2980 minority that can handle CQL queries themselves.
2982 --- 2.0.2 2003/04/28
2984 New Debian package layout similar to the Redhat Package layout.
2986 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2987 and search result respectively.
2989 --- 2.0.1 2003/04/25
2991 Redhat package is now several packages: libyaz (runtime libraries),
2992 libyaz-devel (development and documentation, and yaz (utility programs).
2993 Package spec file by Morten Bogeskov.
2995 New member 'schema' in struct bend_fetch_rr which the name of requested
2996 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2997 handler MAY set this to reflect the schema of the returned record.
2999 New member 'display_term' in struct scan_entry. GFS now sets member entries
3000 and allocates scan entries to be filled by user scan handler. In previous
3001 version, entries member was allocated by the scan handler. That still works,
3002 but the GFS will ignore member display_term - assuming it was NOT set by
3003 the handler. The fact that the GFS now allocates the entries both allows
3004 for new members and makes a scan handler easier to write.
3006 Fix CQL lex buffer overflow.
3008 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3009 SRU default recordPacking is string.
3011 SRU protocol support for frontend server.
3013 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3015 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3017 Added scan for the ZOOM shell (zoomsh).
3021 * String Identifers for Schemas (Amendment 5).
3022 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3023 Old definition for schema
3024 Odr_oid *schema; /* OPT */
3029 Z_InternationalString *uri;
3030 #define Z_Schema_oid 1
3031 #define Z_Schema_uri 2
3034 * resultCount parameter to Sort Response (Amendment 1).
3035 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3037 Support for SRW 1.0 over HTTP. This is an optional feature and
3038 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3041 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3042 on the same port. SRW SearchRetrieveRequests are mapped
3043 to bend_init,bend_search,bend_fetch,bend_close.
3045 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3047 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3048 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3050 ZOOM connections are SRW based if schem http is used for hostname
3051 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3052 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3054 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3055 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3056 distance=n, order=true/false, relation=le, prox unit=word. If
3057 n is omitted, distance 1 is used.
3059 Fixed problem with C compiler include path in wrong order.
3061 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3062 on Solaris. Patch from Ko van der Sloot.
3064 New MARC decode API. All new functions operate on a yaz_marc_t
3065 handle. The most important new functions are: yaz_marc_create,
3066 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3067 decode and destroy respectively. Decoder can produce formats
3068 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3069 include/yaz/marcdisp.h.
3071 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3072 to UTF-8, UCS-32, wchar_t or Latin-1.
3074 * Prototypes for yaz_iconv_-functions moved to separate header
3075 include/yaz/yaz-iconv.h.
3077 Make a few private functions 'static' in unix.c. This prevents
3078 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3080 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3081 are set when Init Response is received.
3083 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3084 but returns diagnostic set as well.
3086 New function yaz_strerror which is a portable wrapper for
3087 strerror/strerror_r/GetLastMessage.
3089 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3090 is returned for MARC. If type is "oai", then OAI MARC is returned.
3092 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3095 --- 1.9.2 2002/11/26
3097 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3099 Fix bad race conditions on SIGTERM and terminate gracefully in
3102 Move retrieval (data1) module to Zebra since nobody seems to be
3105 Add GRS-1 render for ZOOM using same format as yaz-client.
3107 --- 1.9.1 2002/10/05
3109 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3111 Fix broken ESpec handling in data1 module.
3113 SGML reader parses comments and makes them part of the data1 tree.
3115 Added several type casts so that YAZ compiles as C++ code.
3117 ZOOM didn't handle PDU encoding failures properly.
3119 Added more Bib-1 diagnostics (approved extensions).
3121 GNU configure: better check for iconv.
3123 More portable use of accept, getpeername. Check for socklen_t. Use
3124 int/size_t if socklen_t is not defined.
3128 PQF parser rejects bad queries - including those with extra
3129 characters in them. PQF parser used to silently ignore that.
3130 Cleaner API for PQF added, which allows you to get detailed
3131 error information for bad queries (see yaz/pquery.h).
3133 Fixed bug in ZOOM_record_get for type "database".
3135 Implemented mini iconv library supporting conversions between
3136 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3138 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3140 --- 1.8.9 2002/08/20
3142 Fixed ZOOM C record cache so that preferredRecordSyntax and
3143 elementSetName is used to check for already fetched records.
3145 --- 1.8.8 2002/08/02
3147 Added three members in bend_initrequest structure to facilitate
3148 character set negotiation.
3150 Fixed a bug in frontend server that could cause indefinite
3151 loops under rare conditions.
3153 Revised character set utilities (charneg.h) so that encoding
3154 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3156 For PQF, directive @term <type> sets term type for Scan/Search.
3157 Here <type> is general, string, numeric, null. The term type
3158 is inherited - just like @attr.
3160 New call odr_set_charset that sets character set conversion for
3161 international-strings on a ODR stream. Prototype is:
3162 int odr_set_charset(ODR o, const char *to, const char *from);
3163 The InternationalString is still represented as C string in YAZ
3164 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3165 won't). On the protocol level, you can use any encoding.
3167 Support for UNIX sockets in ZOOM.
3169 Solaris recv sometimes returns errno == ENOENT. It is treated as
3170 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3172 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3173 both client and server. Code by Morten Bogeskov.
3175 --- 1.8.7 2002/05/22
3177 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3178 that they can be used directly from Visual Basic. You must recompile
3179 your windows APP if you're using ZOOM.
3181 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3182 Commands "lang" and "charset" sets language and character set respectively.
3183 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3184 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3186 Attributes from multiple CCL fields may be OR'ed rather than merged
3187 using directive "@field or". Fields are still merged by default -
3188 equivalent to "@field merge".
3190 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3193 Fixed bug in zget for parameter ExtendedServicesResponse.
3197 --- 1.8.6 2002/03/25
3199 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3201 Client displays USR.1:SearchResult-1 (hits per term).
3203 Additional Search Info for search in Generic Frontend Server.
3205 Fixed CCL parsing of "field=s".
3207 WIN32 installer - using the excellent NSIS software from nullsoft.
3209 Fixed CCL parsing of "field = - <number>".
3211 Added function yaz_marc_decode that decodes MARC for line mode
3212 display or XML (similar to that used by JZKit).
3214 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3215 Z39.50. But ISO/ILL was, however.
3217 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3218 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3221 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3223 --- 1.8.5 2002/02/03
3225 New YAZ client features: Command completion and new commands:
3226 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3227 Code provided by Jacob Poulsen.
3229 New call oid_trav, that visits all registered OIDs via callback.
3231 Function ZOOM_record_get now returns const char pointer rather than
3232 void pointer. It saves a lot of type casts.
3234 For YAZ client, command "auth" now allows you to set authentication
3235 in IdPass style. It is enabled when three tokens are given - order
3236 is user, group and password.
3238 Fix memory leaks in MARC record handling for ZOOM.
3240 New option for YAZ client, -k <kilobytes> that sets
3241 maximum record size. Similar to -k option for generic frontend
3242 server and yaz-ztest.
3244 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3246 Prefix query parser reports "fail" when bad attribute set is given.
3248 Fix in MARC decoder. Proximity logging. Fix for attribute set
3249 in scan handler for server. Patches by Shigeru Ishida.
3251 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3254 Configure option --with-openssl=<dir> now works when a directory is
3255 specified. Patch provided by Morten Bogeskov.
3257 New option for YAZ client, -u <auth>, that sets authentication.
3259 ZOOM fix: error information was sometimes "missing", since error
3260 was cleared/reset too when it shouldn't.
3262 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3264 --- 1.8.4 2002/01/04
3266 Scan for ZOOM API. New object ZOOM_scanset. New functions
3267 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3268 ZOOM_scanset_destroy.
3270 New ZOOM function, ZOOM_connection_last_event, that returns type
3271 of last event (such as "receive data", "send data", "apdu received",
3274 New ZOOM option, schema, that specifies schema for retrieval.
3276 New CCL feature. Qualifiers can be aliases for one or more
3277 other qualifiers (if more than one is given, OR is used).
3279 ZOOM uses named result sets if target supports it.
3281 Two new YAZ client commands: . (dot, which sources a script of YAZ
3282 client commands), and ! (to execute shell command.). Implemented
3285 Working on Debian packages.
3287 --- 1.8.3 2001/11/19
3289 YAZ client enables named result sets only if target supports it.
3291 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3293 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3294 with key="host" to get same result.
3296 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3297 Function Z3950_resultset_record(s) returns references to records
3298 "owned" by resultset. To become owner use Z3950_record_clone.
3300 Function z_ext_record handles Extended Services. Thanks to
3303 --- 1.8.2 2001/11/12
3305 CCL Parser fix: ignore token comma when dealing with and-lists.
3307 Documentation updates for COMSTACK.
3309 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3310 Changed prototype Z3950_records. For some functions, int parameters
3311 were changed to size_t.
3313 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3316 New MARC decode/display function, marc_display_exl, which properly rejects
3317 non-ISO2709 records. YAZ client uses it.
3319 --- 1.8.1 2001/10/29
3321 Fix bug: local attribute set wasn't set correctly in PQF strings.
3325 * Old Z39.50 codecs no longer supported.
3327 Added ZOOM C binding. See http://zoom.z3950.org/
3329 Renamed states for COMSTACKs to avoid confusion with events.
3331 Implemented cs_look and proper cs_rcvconnect.
3333 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3335 Configure detects POSIX threads on OpenBSD.
3337 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3338 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3340 When error is returned from present handler, non-surrogate diagnostic
3341 is returned in present response (and fetch handler is no longer called).
3343 * Minor adjustments to pquery parser (PQF). Token characters may be
3344 escaped by using backslash (C-style).
3346 PQF parser allows string attribute values to be specified. For @attr,
3347 non-numeric characters after the equal-sign are treated as strings
3348 (e.g. @attr 9=title).
3350 CCL trunction character may be defined (@truncation in file)
3352 * function zget_ExtendedServicesRequest sets waitAction to
3353 waitIfPossible (was wait).
3355 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3358 CCL operator names may be set in field definition files (CCL_bibset).
3359 See ccl/bib1 for an example.
3361 Fixes in ASN.1 compiler for C++ compatibility.
3363 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3364 and "op_or" to avoid conflict with C++.
3366 Fixed problem with GNU readline detection on Redhat 7.0.
3368 Added step-size for Scan backend handler.
3370 Fixed bug that made the frontend server crash when no attribute
3371 set was specified for scan.
3373 Front-end server automatically switches to original working directory
3374 when installed as an NT service. Previously -w had to be specified to
3377 Added extended attributes for retrieval module (data1), so that data1
3378 records carry d1_readXML/SGML attributes. d1_read also supports
3379 null-data rules ( <tag/>)
3381 On UNIX when POSIX threads are available, a separate library libyazthread
3382 is created. Programmers should link with that library and the yaz library
3383 when using threads. The reason for the split was that some applications
3384 on Linux, such as Apache, doesn't work well when using shared objects that
3387 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3388 (or any frontend server) in SSL mode by specifying ssl: followed by
3389 address. Only tested on UNIX.
3391 Added feature for CCL module. Virtual structure s=al or s=ol generates
3392 and-list and or-list respectively instead of phrase search.
3396 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3397 log_mask_str. This was done to avoid name conflicts with other libraries
3398 (such as other PHP extensions).
3400 Added raw OID member for preferred record syntax (request_format_raw)
3401 and returned record syntax (output_format_raw) for backend fetch method.
3403 Config file yaz-config now accepts options so that it returns specific
3404 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3406 Shared library support for UNIX using GNU libtool.
3408 * Modified backend interface. Request/Response struct's replaced by
3409 one read/write C struct. For example bend_fetchrequest and
3410 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3411 Every handler - even search has to be registered in bend_init
3412 handler. This means that the YAZ library no longer refers to
3413 external functions and it makes it possible to make the whole
3414 thing a single DLL/SO.
3416 Added Segment handler for backend server.
3418 Added Zmbol/Zebra administrative functions to YAZ client.
3420 Threaded frontend server on UNIX (when POSIX Threads are available).
3421 Starting the server with option -T enables multi-threading.
3425 Added configure option --enable-comp/disable-comp to control use
3426 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3427 located in sub directory asn.
3429 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3430 in ${exec_prefix}/bin along with the other programs yaz-client and
3433 GNU automake used to maintain makefiles.
3435 Added several OID's.
3437 Changed retrieval module so that we can load records with no abstract
3438 syntax defined. Tagpaths in these records are fully composed of string
3441 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3445 On UNIX, the generated makefile now supports a proper 'make install'.
3446 The prefix can be set via GNU configure to set the install location
3447 (default is /usr/local).
3449 * YAZ programs client and ztest were renamed to yaz-client and
3450 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3451 locations, such as /usr/bin,/usr/local/bin,etc.
3453 * YAZ Header files were moved from include to include/yaz. YAZ Header
3454 files are referred to as include <yaz/log.h> rather than <log.h>.
3455 The YAZ include path (-I ..) is therefore the same as before. Programmers
3456 should update their #include statements or use -Ipath/include/yaz
3457 instead. The main motivation for doing this change is that YAZ header files
3458 can be installed in "standard" locations /usr/include,/usr/local/include
3459 without introducing conflicts, since ALL YAZ header files are stored
3460 in subdirectory yaz (under /usr/include for example).
3462 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3463 rather than project/workspace files. We switched because project files
3464 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3467 Changed name of logging function, logf, to yaz_log, to prevent name
3468 clash with some math-log functions. The YAZ header log.h defines logf
3469 to yaz_log (#define) so there should be no incompatibilities by this
3472 Added bend_start/bend_stop handlers for server. These handler are
3473 called on start/stop of server. For windows they are called whenever
3474 a service is started/stopped.
3476 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3477 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3478 in util/yc.tcl. The auto-generated C code structures are, in a few
3479 cases, incompatible with the old decoders. There are differences in the
3480 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3481 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3482 The preprocessor variable ASN_COMPILED is defined when the compiled
3483 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3484 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3485 wish to use the old encoders/decoders you can specify --disable-yc
3488 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3489 version so that it supports both new - and old version of DB Update
3491 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3492 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3493 change. The name parameter can be set to 0 in which no name is specified
3494 for the construction. The macros odr_implicit and odr_explicit sets name
3495 parameter to zero for the construction involved. New macros
3496 odr_implicit_tag and odr_explicit_tag are similar to the others,
3497 except that a name parameter is added. For programmers' that don't use
3498 ODR they probably only need to change the call to z_APDU and z_External.
3500 Added access control facility by interfacing the TCP wrapper library.
3501 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3502 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3503 name of the daemon and enables the access control as specified in
3504 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3506 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3507 den Dool <H.M.vdnDool@kub.nl>.
3509 Added reference ID parameter to most functions in server API - refer
3510 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3512 Changed name of ccl library to libccl.a (was ccl.a).
3514 Fixed bug in decoder for Explain (Category TargetInfo).
3516 Added support for GNU readline in client. Thanks to Jacob Poulsen
3517 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3519 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3520 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3521 IMPLEMENTATION! This change was made to the development version before
3522 the ZIG decided to retract the amendment. If any users MUST be
3523 compatible with the original Update definition, PLEASE CONTACT US, and
3524 we will include a separate definition corresponding to the old Update
3525 ES. Note that because of the change to the ASN.1 of the
3526 TaskPackageRecordStructure we cannot define a single structure that
3527 will support both versions.
3529 * Added const modifier to buffer parameter for some ODR/BER encoding
3530 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3531 completeWAIS, odr_dumpBER.
3533 Fixed bug in client.c which caused a crash when a scanResponse didn't
3534 contain positionOfTerm.
3536 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3537 * will cause an error in a client if a non-YAZ target sends both a
3538 * list of Scan entries and non-surrogate diagnostics.
3540 Retrieval module enhancements. Tag sets may be typed in the reference
3541 to it. From the .abs-file the "tagset" directive takes a third optional
3542 integer type for the tag set referenced. From a .tag-file the "include"
3543 directive takes a third optional type as well. The old "type" directive
3544 in the tag set itself is still recognized but acts as the default type
3547 Backend interface change. Individual Scan terms returned from bend_scan
3548 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3549 in include/backend.h.
3551 Retrieval module enhancements. Multiple tag sets and attribute sets may
3552 be specified in abstract syntax specs. Revised the error/warning for
3553 logging messages reported by the retrieval module when reading the
3556 Object Identifier system (oid_..) changed. The API is backwards
3557 compatible but the oid-routines now allocates new OID's when needed.
3558 Raw OID's may be specified in oid_getvalbyname.
3560 YAZ now uses GNU configure to generate Makefile(s).
3562 * Minor changes in some of the member names of DeleteResultSetRequest and
3563 DeleteResultSetResponse. See include/proto.h.
3565 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3566 and added member 'languages' in TargetInfo (which was missing).
3568 Changed the way attribute sets are handled in the retrieval
3569 module. These are now cached, just like the abstract syntaxes
3572 Changed YAZ so that it links with compiled ASN.1.
3574 Added Explain-schema definitions and mapping routines. The following
3575 Explain categories have been implemented: AttributeDetails,
3576 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3578 Fixed minor bug in Windows version of Server Library.
3580 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3582 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3584 Added EXTERNAL: UNIverse Resource Report (non-standard).
3586 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3587 ENUMERATED and SET OF.
3589 * Added 'const' to some of the char pointer arguments for the
3590 functions, data1_read_node, data1_getelementbytagname,
3591 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3594 Fixed bug in data1_insert_taggeddata - the last_child member of
3595 parent wasn't initialised.
3597 * Changed data1_read_record and data1_read_node so that the supplied
3598 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3599 doesn't refer to any parts of the "SGML"-buffer.
3601 Fixed bug in server library (Windows version of statserv_remove).
3603 * Changed code so that it compiles as C++. The type definition
3604 of Odr_fun which is a member of Odr_arm was changed. The result is,
3605 that an explicit typecast is needed for the fun pointer when
3606 using Odr_arm - as in:
3607 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3609 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3611 Implemented the new structured date and time definition as approved
3612 by the ZIG. Added schemaId element to the specificTag in Espec-1
3613 (also approved at the last ZIG). Thanks to RVDM.
3615 Added some Object identifiers (RVDM).
3617 Changed the Update Extended Service (RVDM).
3619 Added command "refid" to client which specifies referenceId for
3620 the following requests.
3622 Implemented extended service handling for server. See ztest.c
3623 for an example as well as backend.h. New handlers are registerd
3624 in the Init handler.
3626 * Changed interface for sort in server.
3628 Added new members to statserv_options_block. It allows a server
3629 to read options from another source than just the command line. Thanks
3630 to Charles Woodfield.
3632 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3633 renamed to zboolean. Some C++ compilers complained about the name.
3635 Minor changes to gils.abs. Added index 's' (sort) on title
3636 and date/time-last-modified.
3638 --- 1.4pl2 1998/1/30
3640 Fixed bug in server library regarding inetd mode (-i). This bug
3641 was introduced by release 1.4.
3643 --- 1.4pl1 1998/1/29
3645 Added sort facility in client and backend server interface.
3647 Fixed problem with dependencies in Makefile(s).
3649 Fixed bugs for encoders/decoders of extended services and
3652 Implemented sub-tree feature for schemas. Sub-trees are
3653 referenced in *.abs-files. See explain.abs for an example
3654 of the use of this feature.
3656 Modified bib1.att; local attributes for ANY didn't include
3657 ANY itself (only affects use of the retrieval module).
3659 Fixed bug in plain SGML reader in function data1_read_node:
3660 tags with prefix "var" was incorrectly interpreted as variants.
3662 Added feature "sub-schemas" to enable references to - and definitions
3663 of - group of elements.
3665 * Removed member parent from type data1_element (in data1.h).
3667 Implemented function odr_nullval() that returns the value of
3670 * Removed member num_children from data1_node (in data1.h).
3672 Made NT service interface part of the server library. The
3673 function statserv_main uses the NT service when required and
3674 calls the statserv_start / statserv_close routines.
3676 Routine zget_SearchRequest and zget_PresentRequest fills
3677 resultSetName/Id member with "default" instead of "Default".
3679 Fixed memory leak in server. Request queue member wasn't freed.
3681 Fixed nmem_exit so that memory is freed.
3685 Revised the CCL parser utility to be thread safe.
3687 Added function, oid_ent_to_oid, to replace the function
3688 oid_getoidbyent, which is not thread safe.
3690 * Added nmem_init and nmem_exit to initialize and release
3691 NMEM resources. Function nmem_init should be called once in the
3692 initial thread before NMEM/ODR is used. statserv.c and client.c
3693 have been changed accordingly. The change was necessary to make
3694 NMEM thread safe. The NMEM memory pool is shared amongst threads
3695 in a process. Unix-based applications will still work fine without
3698 Added NT Services interface for the the Z39.50 (statserv) Server.
3699 Refer to the ztest.c source on the usage.
3701 Windows 95/NT port using MSVC5.0. Project files are included in the
3704 * Defined new 'global' handle for the retrieval (data1) system. The
3705 new handled, data1_handle, describes the state of the data1 system.
3706 This handle is passed as first argument to virtually all
3707 data1 related routines. The functions data1_create and data1_destroy
3708 creates and destroys a data1 handle respectively.
3710 Added ODR encode stream member to all backend request structures
3711 init, search, scan etc. This stream should be used to allocate all
3712 memory used for the response when thread safe operation is needed.
3714 Changed the comstack utility, cs_addstr, to be thread safe. The
3715 returned hostname string returned by the function is now part the
3718 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3719 function. The cs_straddr takes a COMSTACK handle as argument, so this
3720 function must be used after cs_create and before bind/connect.
3721 This function is thread safe.
3723 Moved test server to 'ztest' directory - generic server code still
3724 in 'server' directory.
3726 Made prefix query (pquery.c) utility thread safe.
3728 Added new function modifier YAZ_EXPORT to 'export' public DLL
3729 functions when using windows (see include/yconfig.h).
3731 Added definitions to the OID database (util/oid.c) (RVDM).
3733 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3735 Added call to ccl_rpn_delete in client program.
3737 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3738 release of RPN structure.
3740 Added support for C++, headers uses extern "C" for public definitions.
3741 With input from RVDM.
3743 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3744 Thanks to Ronald van der Meer (RVDM).
3746 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3748 Added support for private extensions to the OID database
3749 (oid_setprivateoids()). Thanks to RVDM.
3751 Added optional, physical ANY (key replication)
3753 Fixed null-reference problem in GRS-1 output filter.
3755 Proximity operator added to Prefix Query Format (PQF).
3757 In test client command "base" accepts multiple databases.
3759 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3763 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3765 Smallish bug-fixes in the new encoders/decoders (explain).
3767 Bug fixed in DeleteRequest.
3769 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3771 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3773 Added SOIF syntax (using private OID for now) to retrieval module and client.
3775 Added Update extended service.
3777 Added SearchResult-1 additional info structure.
3779 Added optional CCL (ISO8777) interpreter as separate module. Available
3782 --- 1.2 1996/6/10 (1st anniversary release)
3784 Added Summary record syntax. Lightly tested.
3786 Added OPAC record syntax. Untested.
3788 Added ResourceReport service encoders/decoders. Untested.
3790 Fixed bug in z_Unit - wrong tagging on unitSystem.
3792 Fixed bug in the DiagRecs decoder.
3794 Added options for max PDU size and session timeout to frontend-server.
3796 Added documentation of query-language parsers and other supporting utilities.
3798 [frontend-server] Added Attribute set to the bend_scanrequest API.
3800 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3801 surrogate diagnostics were generated.
3803 [retrieval] Allow multiple local values for attribute.
3805 [retrieval] Allow multiple attributes per element in .abs files. index type.
3807 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3809 --- 1.1pl2 1996/4/10
3811 Minor changes, mostly specific to Zebra's requirements (retrieval)
3815 Repaired bug in frontend server when running multiple listening
3816 endpoints in dynamic mode.
3818 z_External() now won't break if a known, ASN.1 value comes encapsulated
3819 in an octet-string. The value will pass through unmodified in an Odr_oct.
3821 Added a bit of code to the demo client to decode & display
3822 ASN.1-structured records represented in the octet-aligned branch of
3823 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3825 Added z_ext_getentbyref() to the ASN module. Doc updated.
3827 * Completed the SCAN definition in the ASN module. This may break SCAN
3828 code based on older YAZ-versions at compile-time. The fix is easy -
3831 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3832 under the SCAN definition. Remember to initialize this, server-people.
3834 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3835 that this does not extend to ODR and ASN.
3837 Comstack allows insertion of established socket (primarily for
3838 inetd-operation of servers). Doc updated.
3840 Front-end server can now start from the inetd in TCP mode. Doc
3843 --- 1.0pl4 1996/1/24
3847 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3848 the rank and record number.
3850 Adjustments to the frontend server.
3852 Fixed diagnostic BER dumper. It ignored the file argument.
3856 Various changes to retrieval module.
3858 Changed the union discriminators of the protocol files from enums to
3859 ints paired with #defines.
3861 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3864 *Changed operator in the RPN structure to 'roperator', again to avoid a
3867 Fixed problems in Explain decoders/encoders.
3869 --- 1.0pl2 1995/12/6
3871 Memory bug in log module fixed.
3873 --- 1.0pl1 1995/12/5
3875 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3877 Bug in Explain DatabaseInfo module fixed.
3879 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3883 The shift to v1.0 signals that we now consider the *core* functionality
3884 of YAZ reasonably stable (the core being more or less equivalent to
3885 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3886 tested (Explain not at all - though that will happen soonish).
3888 Minor changes to code to support Windows port.
3890 Various minor changes after we're getting to use GRS-1 & co. more.
3892 Added Espec-1 format.
3894 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3895 of the protocol and it cannot be selected when encoding (maps into 'string'
3896 when decoding). Needed to talk to some servers.
3898 Demo client can request simple element set names.
3900 Added Diagnostic Format encoders/decoders.
3902 Added simple Close handling to frontend server (no hooks for resource
3903 reporting yet), and demonstration client.
3905 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3907 --- 1.0b3 1995/08/24
3909 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3910 handled incorrectly when records were requested in the searchResponse. This
3911 will only affect you if you use the frontend-server.
3913 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3914 Test-client will ask for and print GRS1. Ztest will return dummy records
3917 Added Explain encoders/decoders to the service-level API. Untested.
3919 Added Extended Services: Item Order encoders and decoders to the Service-
3920 level API. Untested. We could use a recent copy of the pertinent bits
3921 of the ILL protocol to add those bits.
3923 Added diagnostic format 1 encoders/decoders to the service-level API.
3926 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3927 odr_cons.c, which causes a more correct output.
3929 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3930 was always set to 0 when no records were requested in the searchRequest.
3932 * Added better external-handling. This shouldn't harm old code that
3933 *encodes* externals. It can break code that looks for a
3934 'single-ASN1-type' representation, since those types that are known
3935 are now decoded immediately. Look at the SUTRS sample code in
3936 seshigh.c and client.c. Documentation updated.
3938 Handling of structured records in bend_fetchresponse. Length -1 marks
3939 structured record, type is deduced from format field.
3941 --- 1.0b2 1995/06/27
3942 Fairly quick maintenance release to add SUTRS support.
3944 Fixed handling of SUTRS records in the demonstration client.
3946 * Added format field to the bend_fetchrequest and bend_fetchresponce
3947 structures of the backend API (frontend server). When the record is
3948 returned, the value of the format field is mapped to an OID. The
3949 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3950 of the record. The special value VAL_NONE in the bend_request means
3951 that no specific format was requested by the client. Documentation
3952 updated accordingly. Test server (ztest) will return a fixed dummy
3953 SUTRS record if your client requests SUTRS.
3955 Documentation updated accordingly.
3957 You can now set external libraries and RANLIB support in the top-level
3961 First public release.
