3 Allow more namespaces for SRU. This is to allow, for example, an
4 incorrect namespace returned from server
5 http://services.igi-global.com/sru .
7 Minor fixes for compilation on Windows.
11 daemon: log total number of bad signals from child on stop so that it
12 is more easy to spot problems with child worker processes.
14 retrieval: empty backend name attribute omits element set
15 from being used in retrieval.
19 Implement Solr sort strategy "solr", similar to sru11 sorting.
20 This will implement the correct parameters on Solr requst to do
25 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
28 MARC: Extra/missing indicator handled for MARCXML.
29 The indicator length is given in header and is the same for the
30 whole record. If attributes ind1, ind2 are missing, then content
31 character defaults to blank. Extra indicator attributes (beyond)
32 indicator length are treated as an error.
34 Reformat: delete trailing whitespace
38 MARC: fix non-ASCII characters for leader. This is to ensure we can
39 generate XML in UTF-8.
41 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
42 in one node with structure word.
46 yaz-json-parse: JSON output may be pretty printed by using option
49 Increase default value of max message for Z39.50 Init for GFS, ZOOM
50 and yaz-client. Old value was 1 MB. New value is 64 MB.
54 yaz-client: don't display bogus records from SRU servers. Some SRU servers
55 return more records than given by *maximumRecords*. Skipping those in
58 record_render: simplify buffer return handling and fix at least one bad
59 memory reference, that broke the test_embed_record sometimes.
61 Allow http://user:pass@host notation for yaz_url_exec.
63 zoomsh: allow shell command to be executed. Via the system(3) call.
65 yaz_poll: Allow num_fds == 0
67 yaz-client: fix bad encoding of "itemorder item". The itemorder
68 item <no> - command forgot to use length of encoded Item Request
69 package. Error present since YAZ 3.
71 yaz-ztest: fix bad usage of session handle. Bug was introduced when
72 result sets were saved (271a9c83).
74 SRU recordPacking: guess record packing in response rather than looking
75 at the recordPacking element which, OF COURSE, changed semantics in SRU
78 Decode SRU 2.0 responses. The official namespace for responses, according
79 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
80 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
81 nature.com's server, however, usee namespace
82 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
83 we are now using a glob-expr to match up the namespace. ZOOM C and
84 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
85 I can not find a single real example showing the "real" namespace in
86 the documentation from OASIS. The namespace for requests is different
87 from responses, but this is not added to YAZ yet, when we don't encode
92 zoom/record_render: add support for Base64 decoding fo MARC records
93 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
94 which will decode base64 + ISO2709 marc-8 encoded material from text node
99 Add missing definitions ZOOM_resultset_get_facet_field_by_index
100 and ZOOM_resultset_facets_names.
102 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
105 Change APDU dump printing to avoid long leading blanks. For levels 16
106 or larger the level is shown and the indentation is truncated but
107 recursed with modula 8. This makes it still reasonable easy to read
108 - even for nested BER dumps.
110 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
111 return 0 (incomplete package) in case where the BER package was
112 considered too nested (return value of -2).
114 dumpber: lines of level 15 are not indented further. Two spaces per
115 indentation; indentation 15 or more is indented to a fixed indentation
116 and augmented with a level=<no> indication.
118 zoomsh: increase max size of command+args
120 GFS: No limit in RPN buf size in CQL to RPN conversion.
122 --- 4.2.33 2012/05/09
124 New function for daemon utility, yaz_daemon_stop .
126 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
128 --- 4.2.32 2012/04/25
130 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
131 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
133 --- 4.2.31 2012/04/23
135 YAZ daemon utility relays SIGUSR1 to child process.
137 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
138 would result in en empty database list - which in turn would result in
139 encoding failure for search.
141 Fix reading beyond string in yaz_sort_spec.
143 --- 4.2.30 2012/04/11
145 Add two new SRU diagnostics:
146 236: Access to specified database denied
147 1015: Init/AC: Maximum number of simultaneous sessions for Userid
149 Document the very useful ZOOM-C option "apdulog".
151 CQL to RPN: term may be passed through verbatim. This is enabled with
152 truncation.cql . The assumption being that the term is already CQL.
154 --- 4.2.29 2012/03/20
156 record_conv: leader spec may be given for marc element.
157 The leader spec is given as attribute leaderspec for element marc.
158 For example to convert a MARC21 record from MARC-8 to UTF-8:
159 <marc inputformat="marc" outputformat="marc"
160 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
162 record_conv: allow user-XSLT params. For example:
163 <xslt stylesheet="MARC21slim2DC.xsl">
164 <param name="myparameter" value="myvalue"/>
165 <param name="otherparameter" value="othervalue"/>
168 record_conv: fix error handling for missing marc charsets.
170 CQL: fix extra terms in wrong order.
172 --- 4.2.28 2012/03/06
174 record_conv: modify new API for conversion types. The conversion types
175 may be passed in new functions yaz_record_conv_configure_t and
176 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
178 Avoid mixed statement/variable declare; fixes compilation with Visual
181 --- 4.2.27 2012/02/28
183 Add non-standard SRU diagnostic: 235: "Database does not exist".
184 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
185 Update SRU to Bib-1 diagnostic maps accordingly.
187 CCL: add two new diagnostics for unsupported masking. The new
188 diagnostics are: "Embedded truncation not supported" and
189 "Single charcacter mask not supported".
191 --- 4.2.26 2012/02/23
193 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
195 --- 4.2.25 2012/01/11
197 Build YAZ for Ubuntu Oneiric.
199 CCL: allow parantheses for proximity operands. For example CCL query
200 (a) % (b) is now allowed.
202 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
203 marked dead, rather then being destroyed. If not, the session memory is
204 being free'd before the search/scan handler is finished. Also destroy
205 'request' memory in request_release rather than in various places,
206 which resulted in leaks from time to time.
208 --- 4.2.24 2011/12/21
210 cql_sortby_to_sortkeys: honor sort prefix.
212 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
213 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
214 The rpn2cql family of functions now always returns quoted CQL terms.
216 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
218 --- 4.2.23 2011/12/15
220 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
221 sequence is treated as one. For example, &&a=b&&&c& is identical to
224 --- 4.2.22 2011/12/05
226 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
227 APDUs for a connection to a WRBUF.
229 --- 4.2.21 2011/11/23
231 Fix cql_sortby_to_sortkeys. Completely broken before.
233 Make CCL's @truncation work again.
235 --- 4.2.20 2011/11/09
237 New ZOOM connection setting: tproxy. It's like proxy, but does not
238 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
239 to set resolved address + port for a connection outside ZOOM itself.
241 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
243 --- 4.2.19 2011/11/07
245 Fix uninitialized variable in Solr spell support (could cause SEGV
246 for SRU response decoding).
248 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
249 back-end's addinfo through into the ZOOM response addinfo.
251 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
252 they are separated by a colon and a space rather than simply
255 --- 4.2.18 2011/10/28
257 Add support for Solr spell-checking/suggestions through ZOOM.
258 If a Solr target has been configured correctly for spelling-checking
259 and suggestions, these will now be returned on the ResultSet option
260 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
262 --- 4.2.17 2011/09/28
264 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
265 with a flag whether to substitute escape sequences or not.
267 --- 4.2.16 2011/09/22
269 Fix nmem_strsplit_escape to substitute escape char properly.
271 New option for zoomsh -e , which makes it abort on first error and
272 return process exit code to indicate success/failure.
274 YAZ options utility supports special option -- which makes all it treat
275 all following arguments as non-options.
277 --- 4.2.15 2011/09/16
279 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
280 searched if absolute filename is given.
282 Fix conv_xslt() error-reporting when stylesheet is not found.
283 (The value of fullpath is meaningless in this situation.)
285 --- 4.2.14 2011/09/07
287 Fix problem in CQL sort node creation: un-initialized memory.
289 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
290 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
291 CQL sortby depending on whether Type-1 or CQL is actually sent to the
294 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
295 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
297 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
298 will make it possible to use both single-character mask (#) and wildcard (?)
299 in CCL . Throw diagnostic for left truncation because that is not supported
302 --- 4.2.13 2011/09/01
304 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
305 cases using escapes (\-sequences) and masking.
307 PQF parse fix: A trailing backslash followed by end-of-string (\0)
308 would result in a read one byte beyond string.
310 rpn2ccl may use Z39.50 masking for terms (t=z).
312 ICU check fix. Don't include library -lCrun on Solaris, unless present.
314 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
315 not --cppflags (which seeems like an error in icu-config).
317 --- 4.2.12 2011/08/27 RPM package only
319 cql2ccl: fix conversion of terms: operator characters were not
322 --- 4.2.11 2011/08/25 RPM package only
324 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
325 CCL parser will map both # and ? to their regular expression
326 quivalents (. and .*).
328 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
329 of reserved CQL characters.
331 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
332 is, so that they are passed through.
334 --- 4.2.10 2011/08/24
336 ZOOM SRU mode: more aggressive re-connect.
338 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
339 made available as a utility function, declared in <yaz/logrpn.h>
341 rpn2cql_structure() supports proximity nodes (except that the Type-1
342 proximity node's "exclusion" binary is ignored, as there is no way to
343 express that in CQL). Fixes bug #4564.
347 Fix SEGV that could occur if set command of zoomsh was given without
348 value (2nd argument).
350 Fix SEGV that could occur if unsupported transport was given for
351 COMSTACK - say https (when SSL was unavailable).
353 Build yaz-url on Windows too.
357 New utility to get web content. Header is url.h. A command line tool
358 yaz-url is part of the distribution and packages.
360 Fixes for SSL COMSTACK (when gnutls is in use).
362 New functions yaz_base64{encode,decode}. Header is base64.h.
366 ZOOM C includes HTTP response buffer as additional info if it fails
367 to decode the SRU response.
369 Make wrbuf_json_puts available.
373 zoom: throw diagnostic for invalid value for option "sru". Before a
374 bad SRU request was sent.
376 Adding new utility wrbuf_vp_puts.
378 Add cclxmlconfig.obj to win/makefile. It was missing completely.
382 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
383 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
384 redirect was used at the same time.
386 MARC line mode decoding: be less picky about length given - first
387 5 digits of header that is.
389 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
391 Changes to decoding of SRU records: a record with recordPacking=xml is
392 modified with a new root element <yaz_record> if the recordData contains
393 multiple children elements. This is to make the record XML parseable
396 RPN to SOLR conversion: encode special characters.
398 Generic Frontend Server: fix uinitialized member, stepSize.
402 Fix a bug in SRU decoding of records.. The database records stored
403 had un-initialized memory, but it would only be seen with yaz_record_render
404 and type_spec="ext" .
406 Fix a bug in ccl_qual_dup introduced in 4.2.3.
410 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
414 Add new utilities to convert from CQL to CCL . These utilities have
415 prefix cql_to_ccl defined in cql.h.
417 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
418 lead to memory heap corruptions when ICU utilities were in use.
422 Make compilation work without Libxml2.
424 yaz-client: remove redundant blanks in display of searchResult-1 term
429 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
430 resulting CQL node (tree) in a new node CQL_NODE_SORT.
432 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
433 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
434 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
435 Note that the CQL sortby spec is only converted when the GFS is already
436 converting from CQL to RPN (cql2rpn element).
438 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
439 specify whether to collapse delimitors or not. The existing nmem_strsplit
440 do collapse (collapse parameter = 1).
442 Windows installer: For NSIS, set InstallDir depending on x86/x64.
444 Rename internal func yaz_use_attribute_create. While non-static, this
445 function is not declared in a public header.
449 Add -lCrun when linking with ICU on Solaris.
451 More quicks character set conversions for OPAC records.
455 fix problem with record_render: records were converted (character set
456 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
460 SRU: add methods for handling DADS SRU-proxy facets.
462 Separate OPAC record character set for ZOOM_record. yaz_record_render
463 allows a character set given as charset=from/opacfrom,to where 'from' is
464 the character set of a bibliographic record, 'opacfrom' is character set
465 of OPAC record and 'to' is the target character set.
469 yaz-client: show may XML format records. Command show followed by 'format'
470 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
473 src/stemmer.c: Avoid using unnamed union. It is not supported by some
476 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
479 Update yaz.spec to operate on both SLES11 / Centos 5.5.
481 RPM: Release includes 'indexdata' name. Use indexdata in release name so
482 this package can be distinguished from other vendors.
484 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
485 as determined by configure
487 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
489 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
490 returns no error and no record, the present request is considered
491 partial (only a subset of the records could be returned by backend), and
492 so it is appropriate to set Present Status to partial-4.
496 Move yaz-config man pages to section 1.
498 More documentation about SOLR.
500 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
501 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
502 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
503 peers on some Linux systems. However, in general that does not work
504 so YAZ can not rely on that to work. Debian changed behavior in this
505 respect from Debian lenny to Debian squeeze (still testing as of Oct
507 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
509 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
513 Fix yaz-config output: echo_source not set correctly by configure.
517 SOLR WebService support for yaz-client and ZOOM.
519 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
521 --- 4.0.12 2010/08/17
523 Z39.50 facet support. Facet specifications are passed for search in
524 other-information with ASN.1 as defined in facet.asn and OID
525 .10.1000.81.5 . Facets are expressed as an Attribute list as known
526 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
527 3 is limit (number of entries to get in response). yaz-ztest returns
528 dummy facets if a client asks for them.
530 --- 4.0.11 2010/07/09
532 CCL fixes: bug 2895 and bug 3539.
534 GR1-display: add comma in display - was removed by mistake in
537 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
539 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
541 --- 4.0.10 2010/06/18
543 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
544 result set from a connection. The result set will be on its own
545 thereafter; no operations on it will perform retrievals from a target.
546 Only cached copies are returned.
548 ZOOM C:fix case for HTTP servers responding with Connection:close.
549 Ensure that if there is a current task it is resumed (like fetching
550 more records in a result set) . Bug #3484.
552 PQF parser: use odr_atoi for Odr_int (not atoi)
554 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
555 values that contain any non-digits are treated as string attributes
556 (previously decoding only checked for leading character ([0-9]). PQF
557 encoding: attribute string values are not surrounded by double-quotes.
561 New utility for managing threads - thread_create.h.
563 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
564 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
565 but YAZ' implementation do.
567 Fixes for yaz_cond-functions on Windows 7.
569 DLL export more symbols.
571 zoomsh: show record do NOT render opac.
573 Remove *.la files from Debian and RPM packages.
577 Debian package libyaz-dev depends on libgnutls-dev again (was
578 removed in YAZ 4.0.6, but due to Libtool it is still needed
579 even though yaz-config do not list libgnutls libs).
581 ZOOM: Use only one WRBUF for returning string results for
582 ZOOM_resultset. Reduces memory usage for ZOOM in general.
584 ZOOM: ZOOM_connection do not use a shared pointer to
585 ZOOM_resultset after ZOOM_resultset is destructed by
586 user. Reverts to YAZ 4.0.4 behavior.
590 record-conv: fix problem with at least one XSL conversion -
591 due to probably incorrect usage of XML XSL documents.
595 Fix yaz-config for static mode and the use of SSL (gnutls).
599 Forward decl timeval struct in mutex.h and gettimeofday.h.
601 yaz-config: fix 'static' mode linking.
605 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
606 are wrappers for pthreads or Windows. For Windows these are put in
607 a separate DLL: yaz_cond4.
609 libyaz.la (whole source) is compiled with thread. If thread support
610 is enabled enabled, all source of YAZ is compiled with treading support.
611 This allows core utilities such as yaz_log to use thread facilities.
612 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
613 thread utilities. This commit moves mutex utilities (mutex.c) from
614 libyaz_server.la to libyaz.la.
616 yaz-json-parse displays leading text until error.
620 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
621 patch from Giannis Kosmas.
623 SRU: no longer URL encode SRU database. The URL for an SRU server is
624 a URL and such is alreeady encoded - at least when given with leading
625 http:// or https://. This reverts behavior to YAZ 3.0.50.
627 Support for new MARC XML notation TurboMARC which like MARCXML is a
628 complete representation of MARC/ISO2709.. This one, however, is more
629 compact and allows for faster processing with XSLT. TurboMARC can be
630 used in the marcdisp.h API, from the yaz-marcdump utility and from
633 yaz-ztest can be configured - via the database - to perform certain
634 delays when it performs operations search, present and single record
635 fetch. This allows testers to make yaz-ztest act as a real or even slow
636 Z39.50 server. Refer to the yaz-ztest man pages for details.
640 wrbuf_destroy allows NULL WRBUF passed to it.
642 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
644 Add ZOOM_connection_close.
646 No fixed size buffers for ZOOM shell - bug #3257.
648 tstodr: make it work on s390 platform.
650 New icu iterator-functions. The new icu_iter-functions makes it possible
651 to use ICU chains from many threads.
653 yaz-client: better syntax check for show command.
657 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
660 New simple local-file XML include facility which allows file glob-patterns.
661 Refer to yaz/xml_include.h.
663 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
666 ZOOM_record_get supports new parameter "format" which makes it format XML
669 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
670 JSONText in ECMA-262) is JSONValue, not JSONObject.
674 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
675 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
677 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
678 POSIX/Unix builds .so with major version 4.
680 Remove old LOG_-defines from log.h. They have been obsolete and
681 undefined by default for the last 5 years.
683 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
685 GFS: Remove socket (int *fd) from search_rr handler. The socket
686 descriptor ptr is a facility that allowed a search handler to supply
687 a socket which would serve as a callback - when search was complete.
688 This facility has now been in use for years.
690 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
691 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
692 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
693 returns 'const char *' rather than 'char *. The returned string is
694 read-only and should not be modified by applications. COMSTACK cs_close is
695 now a void function - it no longer returns int. No applications check for
696 the value and the implementations has always returned 0.
698 ZOOM: use size_t for scan hit counts and str size. Functions
699 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
700 occ (hit count) and len (string length) are now of type size_t pointer
701 rather than int pointer. This is to be able to represent large hit counts
702 and to also just to use the proper type for string length (strlen result).
704 New JSON parser. Refer to include/yaz/json.h .
706 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
707 Used to be int in some cases. Many wrbuf_-functions used to return an int
708 indicating some length.. These return values were never used. And so they
711 ODR: odr_malloc, odr_total now takes size_t for size.
713 clone_z_type: fix leak; occurred for encoding failures.
715 --- 3.0.52 2009/12/03
717 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
718 bug was introduced in 3.0.51.
720 --- 3.0.51 2009/12/02
722 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
724 tcpip comstack: fix leak for getaddrinfo.
726 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
727 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
728 Decoding of SRU "path" database is performed by private function
729 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
730 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
732 yaz-client: honor base command for SRU. Change when database setting
733 is applied for SRU and ensure it is kept when a connection is reset.
734 Change also the way errors are displayed or SRU (decoding of packages).
736 --- 3.0.50 2009/11/02
738 Add support for extra request / response data for SRU codecs and GFS.
739 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
740 for extra data response buffer and length. For the GFS, both request
741 and response data (XML) is carried in extra_args and extra_response_data
742 for the search handler. Patch by Ko van der Sloot.
744 ZOOM: For queries that cannot be converted to the specified rpnCharset,
745 ZOOM now returns a diagnostic on the client-side ('invalid query' /
746 10010). This fixes bug #2113.
748 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
749 cmdfile included a 'quit' command that would result in a memory violation.
751 --- 3.0.49 2009/10/01
753 Make a number of functions defined in xmlquery.c static. These have
754 never been declared in a public header file (yaz/xmlquery.h) and was
755 made public by mistake.
757 Improve speed of character conversions (iconv utilities). This makes
758 conversions from MARC-8 faster.
760 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
761 unless type desired is "raw". This will prevent type "xml" from
762 returning ISO2709 .. Which obviously can not be XML parsed.
764 Fix memory leak in ZOOM that would occur if option apdulog was used
765 on a re-used connection.
767 Frontend server logs HTTP requests.
769 Frontend server now sends Z39.50 close when it times out (sesssion has
770 been idle for too long). Versions 2.0.30 and earlier also sent close.
771 But due to a mistake this was disabled in all versions after that, i.e.
772 the server would just close the socket immediately.
774 yaz-client emits a better message when receiving an unrecognised
775 userInformationField.
777 Skip zero-length subfields when decoding ISO2709. This rare case happens
778 if a record has two FS characters in a sequence. Without this patch
779 there would be a reference beyond char array in using_code_len fragments
782 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
784 --- 3.0.48 2009/08/28
786 The show command offered by the zoomsh command now takes a 3d optional
787 parameter type which is what is passed to ZOOM_record. If the type
788 argument is omitted, "render" is used.
790 RPN to CQL conv may use USE string attributes (bug #2978).
792 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
794 --- 3.0.47 2009/07/08
796 Function yaz_xml2query allows a diagnostic element in the PQF XML
797 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
798 code and additional info respectively.
800 The BER BOOLEAN is now the integral type Odr_bool which still happens
801 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
802 typedef'd to Odr_int. This is still an integral 'int', but it may be
803 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
804 ASN-1 compiler as well as programs has been updated to use the new types.
806 --- 3.0.46 2009/06/08
808 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
809 only the bibliographic record was rendered. For type=opac, an OPAC
810 record is only returned if it is present.
812 iconv: small fix for encoding of advancegreek.
814 yaz-client: avoid double display of SRU/SRW records (bug #2798).
816 yaz-client: option auto_reconnect=on really reconnects.
818 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
820 server: avoid null ptr ref for for yaz_poll errors.
822 build: fix RPM build for RHEL 5.3.
824 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
826 --- 3.0.45 2009/03/31
828 Fixed bug #2709: TCP connect returns Invalid argument.
830 Fixed compilation for mingw.
832 Honor charset for raw records (ZOOM_record_get).
834 Fixed use of errno for threaded mode that was seen on Solaris 10.
836 Fixed argument passing with blanks in value for Windows Service.
838 Disable YAZ' own log rotate by default (no 1 GB limit).
839 The variable l_max_size which specifies the log file limit is set to 0
840 (DISABLED): This is due to the fact that YAZ is most often deployed using
841 logrotate. Also YAZ can not perform log rotate because of unsufficient
842 permissions (setuid).
844 --- 3.0.44 2009/02/17
846 List supported encodings in man page for yaz-iconv.
848 Fixed missing SSL libs for --libs output
850 Re-established OID record syntax application-xml. Nobody should use it
851 but we don't want to change soname because of this symbol being absent.
853 --- 3.0.42 2009/02/02
855 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
857 Added member named_result_sets for init handler struct for the GFS. This
858 allows a server to disable named result sets.
860 Removed OID record syntax application-xml.
862 Added support for rule-based transliterator for ICU wrapper of YAZ.
864 Fixed bug #1902: yaz-icu XML output.
866 Make YAZ checks Emacs friendly.
868 BITSTRING value shows value. Bug #2346.
870 ISO2709 decoding: skip control characters from indicator data.
872 Omit sort key by default in yaz-icu's output.
874 Allow combined single char options (again) for YAZ' options function.
876 Utility yaz-marcdump got option to display YAZ version (-V).
878 Allow YAZ to use ICU 3.4.
880 Added new ICU test case which illustrates removal of diacritics.
882 --- 3.0.41 2008/12/29
884 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
886 --- 3.0.40 2008/12/29
888 For configure, using option --without-xml2 also disables Libxslt/Libexslt
891 Fixed bug #2352: yaz-marcdump crashes for certain record.
893 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
895 Added support for Danmarc2 to UTF-8 conversion.
897 Added support for ISO5426 to UTF-8 conversion.
899 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
900 implementation version.
902 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
904 --- 3.0.38 2008/11/10
906 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
907 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
909 ZOOM C now interprets databaseName option for ZOOM connection as path
912 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
914 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
916 Dummy Libxml2 types no longer defined in headers of YAZ'.
918 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
921 --- 3.0.36 2008/09/26
923 Various ODR chapter fixes.
925 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
927 Added missing source for Windows compilation, mutex.c.
929 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
931 For SRU connections in ZOOM all records up to "count" are now fetched.
933 Fixed crash in generic frontend server (and yaz-ztest) which occurred
934 in Windows due to bad error handling for Libxml2.
936 Added facility for sending arbitrary records (ASN.1 any) using
937 ZOOM C's Extended service update. Patch by Sam Reynolds.
939 New options for ZOOM C's connection, logapdu which makes ZOOM log
942 --- 3.0.34 2008/06/18
944 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
946 --- 3.0.32 2008/06/12
948 Fixed memory violation that could occur when decoding UTF-8. This bug
949 was only present in 3.0.30 of YAZ.
951 --- 3.0.30 2008/06/06
953 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
954 GNU TLS is used by default (if found).
956 yaz-ztest returns OPAC records if a client asks for OPAC.
958 Improved speed of MARC-8 encoding.
960 Added support for lossy and loss-less MARC-8 encoding.
962 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
964 Added new Windows Service wrapper (sc).
966 yaz-client's itemorder command may now send a file.
968 Fixed yaz-marcdump to allow the use of NS prefix for record element.
970 Added new function yaz_log_xml_errors.
972 Allow (but warn) unknown XML attributes in MARCXML parsing.
974 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
976 The UTF-8 to MARC-8 conversion now uses a different set of characters
977 for Greek symbols. Bug #2120.
979 --- 3.0.26 2008/02/21
981 Added yaz_daemon (daemon.h).
983 Fixed bug #2068: pkg-config trouble
985 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
987 --- 3.0.24 2008/01/28
989 Document --with-xml2 option.
991 Added OPAC XML XSD (etc/opacxml.xsd).
993 Allow glob mask for name attribute in retrieval element for the
994 generic frontend server's retrieval facility.
996 Changed yaz_poll_poll to return yaz_poll_except for all returned events
997 except POLLIN/POLLOUT.
999 Fixed error handling in cs_listen. Bug #2037.
1001 --- 3.0.22 2008/01/20
1003 Fixed version in yaz/yaz-version.h.
1005 Fixed bug #2027: Crash when closing connection.
1007 Changed configure so that ICU support is only enabled if only ICU
1008 and Libxml2 is available (because the ICU chain is XML based).
1010 --- 3.0.20 2008/01/15
1012 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1013 is built. Only this DLL depends on the ICU runtime.
1015 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1016 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1018 Changed license of CCL module to 'Revised BSD'. After consultation with
1019 remaining members of the original EUROPAGATE consortium, we are re-issuing
1020 the CCL module without a separate license. The software was developed by
1021 Index Data as part of a research project. The special license was included
1022 to help feed usage information back to the project consortium to support
1023 project evaluation. At this time, the project consortium has long-since
1024 disbanded, and the majority of the original principals have retired. At the
1025 same time, we have significantly modified the software during the following
1026 years, to the point where very practically no original code remains. To
1027 simplify re-use of the software, we have contacted those members of the
1028 consortium who could be reached, and agreed to re-issue the module as a
1029 proper part of the YAZ package.
1031 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1033 CQL closer to being version 1.2 compliant. CQL also allows free-form
1034 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1037 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1038 bug could make Extended services handling crash in the ZOOM layer. This
1039 bug was only present in YAZ 3.0.18.
1041 --- 3.0.18 2007/12/19
1043 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1046 yaz-marcdump reads and writes collection wrapped records.
1048 Handle OPAC for record conversion module.
1050 Fixes for ICU wrapper.
1052 Allow ICU libs to be controlled with --with-icu .
1054 --- 3.0.16 2007/11/12
1056 Added yaz_poll which is a wrapper for select/poll. When poll is available
1057 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1058 sockets to be in use.
1060 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1061 functionality through an XML based configuration (ICU chain). This system
1062 is useful for search facilities such as Pazpar2 and Zebra that needs to
1063 perform tokenization of indexed material. The ICU code in a separate
1064 library libyaz3_icu.a.
1066 Added HTTP tunnel facility for COMSTACK, bug #1752.
1067 This is a facility that allows a Web proxy, such as squid, to tunnel
1068 Z39.50 traffic. This facility is "transparent" to must applications
1069 using YAZ. It's enabled by using pseudo transport connect: followed by
1070 the proxy address, followed by command, then follwed by he regular
1071 "virtual" addresss. For example,
1072 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1074 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1076 --- 3.0.14 2007/09/21
1078 Fixed bad memory reference in ZOOM_record - cuased by member not being
1079 initialized. This was a problem only in YAZ 3.0.12.
1081 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1082 fields were not removed.
1084 Changed the way C code is generated from codetables.xml. Made a MARC-8
1085 conversion trie for each characterSet section rather than codeTable.
1086 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1087 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1089 --- 3.0.12 2007/09/12
1091 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1092 from ZOOM_record_error).
1094 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1096 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1098 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1100 Better SRW-to-Bib-1 diagnostic mapping.
1102 ZOOM C and yaz-client announces SRU version 1.2 by default.
1104 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1107 Fixed in yaz_sru_decode to allow other version than 1.1.
1109 --- 3.0.10 2007/08/22
1111 Added support for SRU scan for ZOOM.
1113 Added support for the use of the older versions or Extended Service
1114 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1115 set to the version , 1=first, 2=second, 3=third. The third version is
1116 what ZOOM C has used so far. And that, obviously, is the default.
1118 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1119 therefore in Zebra and in SimpleServer-based applications). The new
1120 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1121 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1122 which is passed into the back-end search callback function.
1124 Added support for HTTP Basic authentication in clients: the SRU/W
1125 codec encodes the username/password elements of the PDU structure
1126 appropriately, and these may be set using the "user" and "password"
1127 options in ZOOM-C applications (the same options that are used for
1128 Z39.50 authentication).
1130 --- 3.0.8 2007/06/25
1132 Fixed bug #1208: SSL appears to be broken in ZOOM.
1134 Fixed bug #1206: Libxml2 include path weirdness.
1136 Added oid_name_to_dotstring.
1138 Allow elementSetName to be specified for ZOOM C record update.
1140 Allow waitAction to be specified for ZOOM C based for Extended Services.
1142 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1143 syntax OID. Bug introduced in YAZ 3 series.
1145 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1147 --- 3.0.6 2007/06/06
1149 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1150 directory. yaz-client now reads commands from file given by option -f
1151 if specified; then tries to read .yazclientrc in current directory.
1152 Failing that, it reads .yazclientrc from user's home directory.
1154 Added support for correlationInfo Note and ID for Record Update via
1157 Added yaz-client command querycharset which specifies character set for
1158 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1159 (termListAndStartPoint).
1161 Charset ISO5428:1984 is an alias for ISO5428-1984.
1163 Implemented a way to perform scan in a result set using Z39.50. This
1164 is achieved by attaching the result set name in the characterInfo
1165 (type InternationalString) of OtherInformation in the Scan Request PDU.
1166 The result set is identified in the otherinformation by the new OID:
1167 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1168 This allows for scan in result set and faceted search . Zebra did some
1169 of this in the APT term using attribute type 8 and value being result
1170 set. Using the OtherInformation approach for this is cleaner and easier
1171 to work with in proxies and the like. This facility can be used in
1172 yaz-client using new command setscan which takes a result set as first
1173 argument, start position (APT) as second.
1175 Changed decoding of SRU XML packed records to deal with servers that
1176 have recordData with XML data with multiple root nodes. Also make
1177 comparison for recordPacking case insensitive. Again, one server
1178 returns "XML" where others return "xml".
1180 For SRU responses allow Content-Type application/xml as well as text/xml.
1182 --- 3.0.4 2007/05/21
1184 Fixed bug in character set conversion of BER strings. Bug introduced
1187 --- 3.0.2 2007/05/08
1189 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1191 For OID class, use oid_class consistently.
1193 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1196 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1197 character set for bibliographic information interchange". By Giannis Kosmas.
1199 Added documentation on new OID API.
1201 --- 3.0.0 2007/05/02
1203 Changes to generic frontend server interface: added new member
1204 'query_charset' for bend_initrequest structure. A backend init handler
1205 should set this member to its native character set for query terms.
1206 When defined, the frontend server logic will announce this character set
1207 to a client if the negotiationModel bit is set by the client. All server
1208 implementors are encouraged to specify this. If a backend server does not
1209 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1211 Added CCL utility to remove terms (stop words) from resulting RPN
1212 tree. This is handled by functions with prefix ccl_stop_words_ .
1214 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1215 terms in RPN queries.
1217 Clean-up the CCL API. Moved some internal structures from ccl.h to
1218 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1219 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1220 This is replaced by ccl_parser_find_str which takes a string instead.
1222 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1223 libyaz.la is the core of YAZ except the generic frontend server and
1224 does not depend on POSIX threads anymore. libyaz_server.la is the
1225 generic frontend server facilities and uses POSIX thread functionality
1226 if available. The libyaz.la no longer depends on POSIX threads because
1227 the number of global structures is limited. NMEM no longer re-uses blocks
1228 between threads ; it simply free's memory immediately but allocates in
1229 "large" chunks as usual. We don't expect any performance penalties
1230 because of this. The yaz_log system is still using a global log_level so
1231 caution must be taken when modifying it with yaz_log_init_.. +
1232 yaz_log_mask_str. This, however, should not cause any trouble because
1233 these functions are called during initialization of application code
1234 anyway. `yaz-config --libs server` returns libs for server applications;
1235 `yaz-config --libs` returns libs for non-server applications.
1237 New OID database - with public definitions in oid_db.h. Removed old OID
1238 database including the head oid.h and definitions such as enum oid_value
1239 and struct oident. The new OID database uses the same string names as
1240 before but the 'protocol' is gone. There are now only two representations
1241 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1242 converts from string to OID; functions with prefix yaz_oid_to_string
1243 converts the other way.
1245 Change to emit_term() in CQL-to-PQF query translation: when a term has
1246 the /regexp relation modifier, do not process it for leading and
1247 trailing "^" and "*", which have quite different meanings in regular
1250 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1251 write handlers no longer carries a 'last' parameter. This will make
1252 yaz_iconv flush "less" characters. A flush is performed by call to
1253 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1255 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1256 removed, because function yaz_query_to_wrbuf does the same.
1258 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1259 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1261 Deprecated MARC utility functions removed.
1263 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1266 Branch split: YAZ_2_1_55_branch
1268 --- 2.1.54 2007/03/16
1270 Fix to ZOOM-C so that transparent reconnection is properly handled on
1271 connections that are in asynchronous mode.
1273 Fixed compilation on OpenBSD 4.0.
1275 Large strings in GRS-1 records are now properly displayed in yaz-client.
1277 Added character conversion support for "advancegreek"; based on patch from
1280 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1281 sequence is met. Before the error was not set so it would be unknown.
1283 Adjust yaz-marcdump MARC reader so that it skips until record separator
1286 --- 2.1.52 2007/03/07
1288 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1289 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1290 fd_set structure used as a bitmask for the FDs to be selected on.
1292 Using ACX_PTHREAD macro to check for POSIX threads.
1294 Fixed have-vsnprintf check.
1296 --- 2.1.50 2007/02/23
1298 Fixes for configure on BSD. Bug #900.
1300 Added snprintf/vsnprintf wrappers for systems that don't have
1301 limits (heavens forbid).
1303 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1304 created before all previous tasks were completed and removed from the
1305 task queue, the new task could be removed by a mistake.
1307 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1309 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1311 Fixed bug #832: Problem with MARC/charset in yaz-client.
1313 Fixed bug #668: save command line history for yaz-client.
1315 Fixed bug #830: pkg-config support.
1317 --- 2.1.48 2007/01/23
1319 Extended ZOOM result set options with two options that may be read by
1320 a client: resultSetStatus and presentStatus with values as specified for
1322 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1324 Fixed bug #827: Using SSL fails on Debian etch.
1326 Fixed bug #826: Weird looking chars for set of MARC records.
1328 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1329 that is treated as an ItemOrder with itemRequest being an XML document
1330 external. The value of "doc" is the content.
1332 Extended the GFS search facility. New member of bend_search_rr
1333 'estimated_hit_count' signals that hits is known to be an estmate
1334 (higher or lower than real hit count). New member 'partial_resultset'
1335 signals that the search was partial (hit count is lower or equal than
1336 real hit count). For Z39.50, the information is stored in resultSetStatus
1337 member of SearchResponse APDU. For SRU, the information is signalled
1338 via SRU diagnostic 59: "Result set created with valid partial results
1341 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1343 --- 2.1.46 2007/01/13
1345 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1347 Added ZOOM_connection_peek_event.
1349 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1350 the following new functions:
1351 ZOOM_event_nonblock, ZOOM_connection_process,
1352 ZOOM_connection_get_{socket,mask,timeout},
1353 ZOOM_connection_fire_event_{timeout,socket}.
1354 The existing blocking event handler, ZOOM_event, is a wrapper for the
1355 + blocking ZOOM_event_sys_{poll,select}.
1357 Implemented function ccl_xml_config which parses XML version of CCL
1358 configuration (bug #798).
1360 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1362 Added timings utility (yaz/timing.h)
1364 --- 2.1.44 2007/01/03
1366 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1369 Fixed bug #779: Rotation of apdu.log fails.
1371 Fixed for character set conversions:
1372 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1373 Honor G1 set in MARC-8 decoding.
1375 --- 2.1.42 2006/12/17
1377 Fixed bug #775: char conversion does not handle Alternative UTF-8
1380 Implemented function yaz_marc_read_line which parses MARC line format
1381 records. There is a wealth of formats out there. So far, this function
1382 reads line records produced by yaz_marc_write_line.
1384 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1385 more generic and easier to remember(!) options: -i format and -o format
1386 which specifies input format and output format respectively - where
1387 format is one of "marc", "marcxml", "line", "marcxchange".
1389 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1390 does not print anything except warnings for records.
1392 For yaz-marcdump, added support for MARC split into files (-s) with a given
1395 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1396 spec, at http://www.loc.gov/standards/sru/record-update/
1397 This has changed the binary layout of the following structs:
1398 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1399 bend_update_rr . Patch by Ko van der Sloot.
1401 Added GFS utility function bend_assoc_is_alive which returns 1 if
1402 association is still alive (client is connected); 0 otherwise (client
1403 closed connection). This allows busy servers to stop working for
1406 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1407 been a separate piece of software. This version of ziffy has been modified
1408 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1410 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1412 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1413 Client code may now interrogate options such as "init_opt_sort" to
1414 find out whether the server claims to support various options.
1416 --- 2.1.40 2006/11/27
1418 Added utilities yaz_{set,get}_esn to set/get element set name from
1421 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1422 of YAZ and has been so since YAZ 2.1.10.
1424 Implemented ZOOM_record_error which returns error information for
1425 record (surrogate diagnostic).
1427 --- 2.1.38 2006/10/31
1429 Updates for SRU Update by Ko van der Sloot:
1430 1. Changed name from "operation" to "action"
1431 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1432 versions in the code, marked as 'backward compatible'.
1433 3. Added diagnostics for SRU Update.
1435 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1437 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1439 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1441 For GFS, fixed problem with SRU diagnostic 'First record position out of
1442 range' being issued for 0 hits.
1444 zoomtst10 part of Windows Build.
1446 --- 2.1.36 2006/10/13
1448 Implemented yaz_filepath_comp which splits a path into file path
1449 components (required by Zebra 2.0.3+).
1451 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1452 BSD inspired license until now so this should not have any real impact on
1453 anybody. See http://www.opensource.org/licenses/bsd-license.php
1455 Fixed bug #687: Missing log lines.
1457 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1460 Fixed bug #689: SRU diagnostics to be added.
1462 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1463 whether a connection is idle (no more work do do).
1465 --- 2.1.34 2006/10/04
1467 Change type of optval from long to int for invocation of setsockopt with
1468 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1470 Added support for specifying the max log file size for the Generic
1471 Frontend Server. The size is given with option -r.
1473 --- 2.1.32 2006/09/21
1475 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1477 --- 2.1.30 2006/09/17
1479 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1482 Fixed bug in Generic Frontend Server that could cause a server to stop
1483 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1485 For the generic frontend server, the maximum record size is used as maximum
1486 size of incoming packages (SRU + Z39.50). The value until was previously
1487 only used in Z39.50 Init negotiation and, later, in a session controlled
1488 sizes of records returned. This is controlled using -k option. It can be
1489 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1491 --- 2.1.28 2006/09/04
1493 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1496 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1498 New option for yaz-marcdump -lpos=value which allows setting a portion
1499 of MARC header to a certain value.
1501 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1503 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1504 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1506 --- 2.1.26 2006/08/15
1508 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1511 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1513 --- 2.1.24 2006/08/08
1515 Fixed MARC ISO2709 encoding routines to deal with character set
1518 Minor changes to GFS logging. Database included in search request log
1521 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1522 cached/multiple records.
1524 Shared libraries are built by default on Unix+configure.
1526 Changed cql2pqf transformation to use a different evaluation order. The
1527 new order is: always, relation, structure, position, truncation, index
1528 and relationModifier. Old order was: always, relation, relationModifier,
1529 structure, index, position, truncation. Note that the the latter ones
1530 override former ones for identical attributes.. The new scheme means that
1531 it is possible to override any existing attribute with a relationModifier.
1532 And also that it is possible to override everything for the index rule
1533 (except the ones listed in relationModifier). No order is perfect but this
1534 one, we believe, covers more real cases.. The "always" should have been
1535 called "default", since the attributes there can be overridden with all
1538 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1539 compilation phase, but also for yaz-config --cflags output. This allows
1540 us to have public headers with Libxml2 stuff in them . It should also,
1541 eventually, make Libxml2 checks redundant in packages using YAZ, such
1544 --- 2.1.22 2006/06/15
1546 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1547 stored in uri, message and details.. Previously diagnostics were stored
1548 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1549 compatibility.. but he's probably the only one affected, so.
1551 Added support for CCL, compiled on the client side, in ZOOM-C. This
1552 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1553 input; the resulting query objects can be used for for searching with
1554 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1556 YAZ' configure searches for OpenSSL by default.
1558 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1559 SL_CTX_use_certificate_file. See
1560 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1561 for more info. Thanks to Ko van der Sloot.
1563 --- 2.1.20 2006/06/02
1565 Bug #600: SRU GET, POST support for yaz-client. Introduced
1566 command 'sru' which selects method SOAP/GET/POST.
1568 Allow missingValueAction to be specified for the sortspec string -
1569 function yaz_sort_spec. By default, the missing value action is null.
1570 Use ! to specify "abort". Use = followed by stringvalue to specify default
1573 Ensured that Present-handler (if defined) is called in GFS before any call to
1574 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1575 searchRetrieve requests.
1577 Documentation for YAZ is now based on the Docbook XML/XSLT using
1578 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1579 is no longer depending on jade/openjade or docbook-to-man scripts.
1580 PDF is no longer part of the distribution - but can optionally be
1581 made using DSSSL/jadetex or FOP.
1583 Added retrieval handling support in Generic Frontend Server to support
1584 conversion between MARC/XML as well as XSLTtransforms. See
1585 etc/yazgfs.xml for an example.
1587 Added Authentication support to Generic Frontend Server in SRU
1588 mode. Authentication using HTTP Basic is supported, as is the use
1589 of 'x-username' and 'x-password' parameters in the request itself.
1591 Added support for a new character set MARC8s identical to MARC8 except
1592 that it converts combined characters to single Unicode characters in the
1593 Latin-1 range (when possible).
1595 --- 2.1.18 2006/04/24
1597 ASN.1 compiler 0.4: generates brief Doxygen file header for
1598 generated .h/.c files.
1600 Utility yaz_iconv now supports conversion to MARC-8.
1602 New facilities for the MARC module. The reading - and writing of
1603 content are separate methods for the yaz_marc_t handle. The following
1604 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1605 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1606 format). Write functions have prefix yaz_marc_write_.. The existing
1607 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1608 available. Removed support for OAI-MARC and simplexml (not the
1609 simplexml from PHP5).
1611 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1612 to be returned for this connection.
1614 --- 2.1.16 2006/03/31
1616 Allow multiple languages and charsets to be specified with
1617 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1618 negcharset iso-8859-1,utf-8
1620 Translation of proximity nodes from CQL into PQF now works.
1622 Moved to automake 1.8, 1.9.
1624 Added function yaz_log_set_handler which allows a log handler to be
1625 installed. This handler will be called for all log messages. Output
1626 to file is also produced; but that can be disabled by passing NULL
1627 fname to yaz_log_init_file.
1629 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1631 For SRW (including GFS), accept application/soap+xml as content-type
1634 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1635 produces NO stylesheet reference even if a default stylesheet is specified
1638 --- 2.1.14 2006/03/14
1640 Updated Windows package to include yazd.dll + yazd.lib for the
1641 Development component.
1643 If the environment variable YAZ_LOG is set, then it is used as a
1644 string indicating the default level of logging to use if not
1645 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1646 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1647 used as before. So, for example, to omit warnings from YAZ logging,
1648 export YAZ_LOG=-warn
1650 cql_transform() now map structure and other attributes before indexes,
1651 so that index-specific structures and other attributes can override
1652 defaults. So now a combination of mapping specifications such as:
1654 index.dc.date = 1=date-modified 4=5
1655 does the right thing.
1657 cql_transform() now also respects the "always" mapping specification,
1658 which establishes an initial set of attributes to be used for all
1659 terms except where overridden by more specific attributes associated
1660 with the index, relation or modifier.
1662 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1663 which mode to use; one of "post", "get" or "soap" (SRW, default).
1665 Fixes for yaz_iconv routines: changed trie-based character set conversions
1666 to use only non-negative values for bit fields due to Sun's C compiler not
1667 supporting negative values.
1669 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1670 sequences where not read correctly. Fix by Rustam Usmanov.
1672 Updated win/makefile to use options, settings which makes things
1673 compile with VS C 2005.
1675 --- 2.1.12 2006/02/01
1677 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1679 In ZOOM socket code, use select instead of poll on MacOSX.
1681 ZOOM-C now support client-side compilation of CQL into RPN that is
1682 sent to the server, enabling CQL to be used against all Z39.50
1683 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1684 ZOOM_query object, and submit it using ZOOM_connection_search().
1685 The CQL-to-RPN translation uses a configuration file, the name of
1686 which must be specified in the Connection's "cqlfile" option.
1688 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1689 function, which takes as its start-term parameter a ZOOM_query object
1690 (which may have had either CQL or RPN set into it).
1693 --- 2.1.10 2005/11/29
1695 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1696 GFS to support this as well. Backend handler, bend_srw_update, does the
1697 update work. Code contributed by Ko van der Sloot.
1699 Allow retrieval of Search Result-1 information in ZOOM by the use of
1700 options that are attached to a result set. ZOOM documentation updated
1703 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1704 UTF-8 conversion. Patch by Raj Patel.
1706 Added option -m to GFS to control formatting of timestamps in log file.
1708 Added 'exit' as synonym for 'quit' in yaz-client
1710 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1711 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1712 for the new members. Patch by Ko van der Sloot.
1714 Added support for SRU POST. It is supported for content-type
1715 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1717 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1718 Instead make the library libyaz.la multi-threaded. Threading as a whole
1719 can still be disabled by configure option --disable-threads. Previosly,
1720 with older GLIBCs there were problems with MT libs under Apache. This
1721 has now been fixed a long time ago.
1723 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1726 CQL module modified to be case insensitive for relations/indexes/operations.
1728 Fixed bug in CQL transform code: incorrect value relationModifieder
1731 Added 'show all' command for yaz-client which retrieves all results
1734 Added new yaz-client, xmles, which takes a (private) OID and
1735 a document to be sent as an extended service request.
1737 Describe new yaz-client commands wait_response and set_auto_wait.
1739 Increase TCP/IP listener backlog from 3 (which I am guessing was
1740 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1741 that the socket will queue as many incoming connections as it's able
1742 to handle ongoing connections. In other words, it will never now
1743 refuse a connection that it would be able to handle merely because
1744 it's not got around to accepting() enough of the pending connections
1745 yet. This is the behaviour anyway under Linux, where the listen()
1746 argument is ignored; but not under BSD and on systems such as
1747 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1748 YAZ-based servers should now be uniform across operating systems in
1751 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1752 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1753 This allows yaz-marcdump to read large MARC batches (>2 GB).
1755 Modified all YAZ source files - except the source which is auto-generated
1756 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1759 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1760 corresponding to the existing *_setl() function. These allow option
1761 values containing arbitrary valuues.
1763 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1764 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1765 except that it returns an indicator of whether or not the sort
1766 criterion was accepted (0 for OK, -1 for invalid).
1768 --- 2.1.8 2005/06/07
1770 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1771 MARC output rather than returning "new" buffer.
1773 yaz-client warns about unknown init options.
1775 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1777 --- 2.1.6 2005/05/24
1779 Added support for SRW sort in Generic Frontend Server. Patch
1780 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1781 sortKeys - or NULL if none is provided.
1783 Fixed bug #307: It was impossible to specify indefinite/no timeout
1784 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1787 Added support for multiple languages and charsets to be specified in
1788 ZOOM. Each charset/language is separated by a blank. If negotiation is
1789 in effect in init-response, Option
1790 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1791 Code based on patch by Vasiliy Osadchuk.
1793 Fixed bug #306: infinite recursion that occurred when calling
1794 yaz_log_level_init as the first call (before other log level or
1797 Fixed bug in scan handling in front end server: if preferred-Position-In-
1798 Response was non-present, a NULL pointer referece was performed.
1800 --- 2.1.4 2005/04/26
1802 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1803 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1804 now defined for all those error codes. So instead of putting 109 in
1805 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1806 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1808 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1811 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1813 Program yaz-client now exits and produces an error message if multiple
1814 Z39.50 servers are specified on the command line (none or one allowed
1817 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1820 --- 2.1.2 2005/03/16
1822 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1824 Fixed bug #272: Preserve spacing for CCL terms.
1826 --- 2.1.0 2005/03/14
1828 Added support for virtual hosts and multiple backend servers for
1829 the YAZ frontend server. The configution is XML based and
1830 support specificition of CQL to RPN mappings and explain information.
1831 See section "Virtual Hosts" in the YAZ manual.
1833 Extended OPAC display utility. OPAC display utility renders
1834 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1835 to supplement yaz_marc_decode_wrbuf.
1837 Fixed a bug in MARC decoder that could caused it to crash for some
1838 invalid MARC records. More diagnostics and warnings where added in
1839 XML output (warnings, etc are stored in comments).
1841 --- 2.0.34 2005/02/08
1843 Fixes for UNIX domain sockets. Bug #261.
1845 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1847 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1848 Added yaz_marc_subfield_str which defines subfield lead string which is
1849 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1850 yaz_marc_endline_str which defines end of fields string used in
1851 YAZ_MARC_LINE format. Default string is newline.
1853 Experimental support for MarcXChange. This format can be produced
1854 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1855 http://www.bs.dk/standards/MarcXchange.xsd
1857 Added yaz-client commands scansize that sets maximum number of
1858 entries to be returned by scan.
1860 --- 2.0.32 2005/01/11
1862 Added support for SRW scan in yaz-client and Generic Frontend Server.
1864 * Added whereInList member to SRW Scan Term.
1866 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1868 Fixed NMEM system to return aligned blocks on the smallest boundaries
1869 that are suitably aligned for all possible types on the particular
1870 architecture YAZ is being built for.
1872 --- 2.0.30 2005/01/04
1874 Fixed numerious warnings that was issued with newer versions of GCC.
1876 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1877 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1880 Make YAZ Generic Frontend Server slightly faster.
1882 Enhance (and reduce) logging for Generic Frontend Server.
1884 Revert YAZ log system so that it flushes every write operation
1885 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1887 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1888 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1889 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1890 will effectively disable old definitions.
1892 --- 2.0.28 2004/11/09
1894 Added yaz_log_time_format which specifies log format using
1897 Added yaz_log_module_level which returns mask for a module. Value
1898 is non-zero mask a if module is enabled; zero if disabled.
1900 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1901 in include/yaz/cql.h.
1903 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1905 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1907 Fixed bug #172: RPM builds does not enable SSL.
1909 Doxyfile.in part of dist. Doxyfile generated by configure.
1911 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1912 are given and the corresponding component does not exist.
1914 Extend CCL documentation in YAZ reference. Describe r=r.
1916 --- 2.0.26 2004/10/01
1918 Fixed MARC->MARCXML conversion to properly deal with
1919 fields, subfields, indicators having non-ASCII characters.
1921 Fixed MARC->MARCXML conversion so that ASCII control characters
1922 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1925 Added YAZ GFS support for conversion from Z39.50 surrogate
1926 diagnostics to SRW surrogate diagnostics.
1928 Bug fix: YAZ GFS did not return schema in explainResponse.
1930 --- 2.0.25 2004/09/30
1932 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1933 now converts recordSchema to elementSetName as well as schema URI.
1935 Fixed bug in COMSTACK that prevented HTTP request packages from being
1938 --- 2.0.24 2004/09/29
1940 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1941 does not require white-space before and after the dash in a range, e.g.
1942 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1945 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1946 due to new GCC removing "redundant" code.
1948 Added yaz-client commands scanpos and scanstep that sets preferred
1949 position and step-size for scan.
1951 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1953 Added CCL utility ccl_qual_buf which parses one or more CCL
1954 spec lines in a buffer.
1956 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1957 of name and value - ignoring empty lines and comments.
1959 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1961 Added odr_get_element_path which returns current element path for an
1962 ODR handle. This utility is useful in error handling or user-defined
1965 Added ODR_PRINT utility odr_set_stream which is is a more generic
1966 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1967 to a write function and pointer to close function. The close function - if
1968 non-NULL - will be called during odr_destroy.
1970 Fixed bug in CCL parser where truncation char was not removed from
1971 right side when truncation=both was in effect.
1973 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1976 --- 2.0.23 2004/08/11
1978 Fix buffer overrun in CQL parser when dealing with proximity (%).
1980 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1981 to UTF-8/UCS conversion is now only based on codetables.xml.
1983 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1985 --- 2.0.22 2004/08/06
1987 Add support for more "commit changes" in ZOOM (uses Extended Services).
1989 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1992 Yet another small fix for configure of SSL.
1994 --- 2.0.21 2004/05/14
1996 Fix SSL libs for configure when --with-openssl=DIR is given.
1998 --- 2.0.20 2004/05/10
2000 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2002 SSL comstack now uses yaz.pem certificate file on server side
2003 by default. Certificate filename can be configured by calling
2004 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2006 Fix bug regarding multiple calls to ZOOM_connection_connect.
2008 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2010 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2011 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2013 ZOOM now allows inspection of X509 peer certificate for verification.
2014 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2016 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2017 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2018 as "modular" but it simplifies things.
2020 Added cs_get_peer_certificate to that returns peer X509 PEM.
2022 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2023 NULL if SSL is unavailable.
2025 Documentation about MARC decoding tools.
2027 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2029 --- 2.0.19 2004/03/30
2031 Rename CHANGELOG to NEWS to follow GNU style packing.
2033 Fix bug with missing initialization of member in init_diagnostics.
2034 This bug affects threaded version of GFS server.
2036 --- 2.0.18 2004/03/20
2038 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2041 Ensure zlib.dll is packed with Windows install.
2043 --- 2.0.17 2004/03/17
2045 Fix encoding of xsd:string to use text instead of CDATA.
2047 Fix endless loop in CQL parser with unbalanced ".
2049 Use a more compact way to store MARC-8 conversion tables.
2051 --- 2.0.16 2004/03/16 Debian only
2053 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2056 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2061 --- 2.0.15 2004/03/01
2063 Another fix for decoding of XML packed records.
2065 --- 2.0.14 2004/02/25
2067 Fixes for Chunked encoding. White space not ignored after length spec.
2069 Update NS and use default NS for SRW diagnostic elements.
2071 --- 2.0.13 2004/02/23
2073 Implement ZOOM_resultset_cache_reset which resets record cache.
2075 Implement ZOOM_resultset_sort which sorts a result set.
2077 Implement chunked HTTP transfer.
2079 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2081 --- 2.0.12 2004/02/16
2083 Added member 'schema' to bend_explain_rr structure so that backend
2084 can specify explain record identifier. Defaults to Zeerex 2.0.
2086 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2088 --- 2.0.11 2004/02/16
2090 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2093 Added init command for yaz-client which sends "extra" init request.
2095 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2096 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2098 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2100 Make ZOOM error code for "invalid query".
2102 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2104 --- 2.0.10 2004/02/05
2106 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2109 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2111 Added option -p <file> to make Generic Frontend Server to write PID file.
2113 Added option -D to put Generic Frontend Server in background on its own.
2115 Make ZOOM C recognize option "password". If unset, "pass" is used
2116 (for backwards compatibility).
2118 Fixed a bug in Generic Frontend Server that could make it crash if a
2119 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2122 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2123 Must be issued before open, in order to be in effect.
2125 --- 2.0.9-6 2004/01/12 Debian/Windows
2127 Make the SRU server more picky WRT unknown params, etc.
2129 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2131 New YAZ client command, options, that sets Z39.50 options.
2133 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2134 options from a string of tokens (one token for each option bit).
2136 Update SRW diagnostic code messages.
2138 --- 2.0.9-5 2004/01/07 Debian/Windows
2140 Handle user defined stylesheet for SRW/SRU.
2142 --- 2.0.9-4 2004/01/06 Debian/Windows
2144 Fix bug in decoding of Content-Length.
2146 --- 2.0.9-3 2004/01/06 Debian/Windows
2148 Fix a bug with decoding of XML packed records.
2150 --- 2.0.9-2 2004/01/05 Debian only
2152 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2154 Fix bug in SRW/SRU diagnostics decoding.
2156 --- 2.0.9 2004/01/05
2158 Fixed bug in Generic Frontend Server which could drop records exceeding
2159 preferred message size. Reported and fixed by Irina Dijour.
2161 Fixed calculation of package size for structured records in Generic
2162 Frontend Server. Reported and fixed by Irina Dijour.
2164 Fixed namespace for SRW/SRU diagnostics.
2166 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2168 --- 2.0.8 2003/12/22
2170 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2171 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2174 CQL changes to reflect recent changes to the specification:
2175 * Documentation talks about context sets instead of index sets.
2176 * Documentation talks about indexes instead of qualifiers.
2177 * The CQL-to-PQF transformer's configuration file now uses
2178 "index.set.name = <attributes>" instead of the old form
2179 "qualifier.set.name = <attributes>". (Both forms are still
2180 understood but the latter is deprecated.)
2181 * CQL terms with no explicit index specified are now interpreted as
2182 cql.serverChoice instead of srw.serverChoice (which of course
2183 behaves exactly the same.)
2185 --- 2.0.7 2003/12/16
2187 MARC conversion can now generate ISO2709 output in another
2188 character set. yaz-marcdump uses this facility if you invoke it
2191 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2192 functions from there can be used from C++.
2194 --- 2.0.6 2003/12/04
2196 Frontend server now transfers memory from decoded packages to stream
2199 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2200 references to show up.
2202 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2203 the ZOOM Abstract API. The older names for the same options are still
2204 also supported for the benefit of old applications.
2206 ZOOM-C supports "implementationId" and "implementationVersion" options
2207 to go along with "implementationName". These allow the user code to
2208 specify identification strings to be sent to servers.
2209 Add OID for the new ExtLite attribute set.
2211 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2212 as requested/supplid by Ere Maijala <ere@atp.fi>
2214 For generic frontend server, reverse the order of
2215 "toolkit-supplied / application-supplied" strings sent as implementationId,
2216 Name and Version. Also, remove the spaces around the slash. This brings
2217 the GFS in line with the behaviour of ZOOM-C on the client side.
2219 Add function ZOOM_scanset_display_term.
2221 yaz-client shows scan displayTerm if present.
2223 Utility yaz-iconv is now installed by default along with the man page
2226 Extend configure check for OpenSSL to use pkg-config where available (such
2229 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2230 server to specify uid/gid/mask for socket using the format
2231 unix:[user=uid,][group=gid,][umask=mask,]file=path
2232 If file= is omitted the existing format is assumed, e.g.
2234 in which case the mask is 0666 (rw for everybody).
2236 Major restructure of YAZ source. All source in libyaz is in src directory.
2237 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2238 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2240 Added man page for utility yaz-marcdump (used to be called marcdump).
2241 yaz-marcdump is installed by 'make install'.
2243 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2244 of incoming package failed.
2246 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2248 Change prototype of odr_perror: add const to message string.
2250 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2252 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2253 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2254 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2255 DNS lookup. There should not be any compatibility problems with this
2256 assuming that blocking=1 or 0 is used.
2258 Fix bad reference in UNIX comstack in function cs_addrstr.
2260 Fix for compilation on AIX.
2262 The generic front-end server (server/seshigh.c) now supports returning
2263 Init diagnostics to the client in User-information-field, in
2264 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2267 --- 2.0.4 2003/09/04
2269 Allow any CQL relation (not just all,any,exact,scr).
2271 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2272 that features the same UI.
2274 Implemented command update0 in YAZ client which is equivalent to
2275 update but uses old of Ext Update ASN.1.
2277 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2278 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2279 Previously no OID was used for this info.
2281 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2282 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2283 returns 'malformed search term' otherwise.
2285 SortResponse member resultCount now set to NULL in sort handler of
2288 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2291 Add three new utility functions for translating OIDs between various
2292 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2293 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2294 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2295 char *oid_to_dotstring(const int *oid, char *oidbuf);
2296 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2298 Reverted modifications for ES Update definition for z_IU0Update
2299 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2300 is back to YAZ 2.0.2.
2302 String value attributes for CCL parser.
2304 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2305 which their FirstSearch server returns in Init responses, sometimes
2306 carrying useful diagnostic information when Init fails. This has the
2307 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2308 "z39.50/oclcui.asn", where its definition is somewhat different from
2309 what OCLC document on their web-site, as required to interoperate with
2312 Support for anonymous authentication in yaz-client. Use the command
2315 * Fix the OID of the Index Data-local "admin" Extended Service from
2316 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2317 the 1000, which indicates a locally-defined OID, was a mistake.
2319 --- 2.0.3 2003/06/20
2321 Fix CCL directive @case handling so that it affects string match for
2322 both CCL keywords and qualifiers.
2324 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2325 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2326 Decoder has been updated with ASN.1 changes as listed in
2327 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2328 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2329 z_IUUpdate, remains unchanged.
2331 ZOOM_record_get may now return a record in a specific character set.
2332 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2333 "from" is the character set of record as returned by target. "to" is
2334 the character set to be returned. If omitted, "to" is UTF-8.
2336 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2338 New ODR utility, odr_getelement, which returns name of element for
2339 which encoding/decoding failed.
2341 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2342 in cases where a required element was omitted.
2344 Bug fix: some MARC8 sequences were not converted.
2346 New ZOOM option "step" which specifies number of records to be
2347 retrieved in one chunk. Used in conjunction with "start" and "count".
2349 SRW support for yaz-client. Use scheme http: to use it, e.g.
2352 yaz-client no longer does (un)intelligent character set conversions
2353 by default. Can be enabled with charset and marc_charset commands.
2355 xmalloc trace fix for 64-bit systems such as DEC alpha.
2357 Solaris 2.6 compile fix.
2359 New function, cql_strerror() translates SRW error codes, as returned
2360 by cql_transform_error(), into human-readable English strings. Used
2361 in yaz-client diagnostics when appropriate.
2363 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2364 converts it into a type-1 query which is sent to the server. This
2365 makes CQL available for use with all Z-servers, as opposed to the tiny
2366 minority that can handle CQL queries themselves.
2368 --- 2.0.2 2003/04/28
2370 New Debian package layout similar to the Redhat Package layout.
2372 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2373 and search result respectively.
2375 --- 2.0.1 2003/04/25
2377 Redhat package is now several packages: libyaz (runtime libraries),
2378 libyaz-devel (development and documentation, and yaz (utility programs).
2379 Package spec file by Morten Bogeskov.
2381 New member 'schema' in struct bend_fetch_rr which the name of requested
2382 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2383 handler MAY set this to reflect the schema of the returned record.
2385 New member 'display_term' in struct scan_entry. GFS now sets member entries
2386 and allocates scan entries to be filled by user scan handler. In previous
2387 version, entries member was allocated by the scan handler. That still works,
2388 but the GFS will ignore member display_term - assuming it was NOT set by
2389 the handler. The fact that the GFS now allocates the entries both allows
2390 for new members and makes a scan handler easier to write.
2392 Fix CQL lex buffer overflow.
2394 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2395 SRU default recordPacking is string.
2397 SRU protocol support for frontend server.
2399 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2401 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2403 Added scan for the ZOOM shell (zoomsh).
2407 * String Identifers for Schemas (Amendment 5).
2408 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2409 Old definition for schema
2410 Odr_oid *schema; /* OPT */
2415 Z_InternationalString *uri;
2416 #define Z_Schema_oid 1
2417 #define Z_Schema_uri 2
2420 * resultCount parameter to Sort Response (Amendment 1).
2421 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2423 Support for SRW 1.0 over HTTP. This is an optional feature and
2424 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2427 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2428 on the same port. SRW SearchRetrieveRequests are mapped
2429 to bend_init,bend_search,bend_fetch,bend_close.
2431 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2433 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2434 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2436 ZOOM connections are SRW based if schem http is used for hostname
2437 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2438 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2440 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2441 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2442 distance=n, order=true/false, relation=le, prox unit=word. If
2443 n is omitted, distance 1 is used.
2445 Fixed problem with C compiler include path in wrong order.
2447 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2448 on Solaris. Patch from Ko van der Sloot.
2450 New MARC decode API. All new functions operate on a yaz_marc_t
2451 handle. The most important new functions are: yaz_marc_create,
2452 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2453 decode and destroy respectively. Decoder can produce formats
2454 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2455 include/yaz/marcdisp.h.
2457 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2458 to UTF-8, UCS-32, wchar_t or Latin-1.
2460 * Prototypes for yaz_iconv_-functions moved to separate header
2461 include/yaz/yaz-iconv.h.
2463 Make a few private functions 'static' in unix.c. This prevents
2464 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2466 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2467 are set when Init Response is received.
2469 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2470 but returns diagnostic set as well.
2472 New function yaz_strerror which is a portable wrapper for
2473 strerror/strerror_r/GetLastMessage.
2475 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2476 is returned for MARC. If type is "oai", then OAI MARC is returned.
2478 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2481 --- 1.9.2 2002/11/26
2483 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2485 Fix bad race conditions on SIGTERM and terminate gracefully in
2488 Move retrieval (data1) module to Zebra since nobody seems to be
2491 Add GRS-1 render for ZOOM using same format as yaz-client.
2493 --- 1.9.1 2002/10/05
2495 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2497 Fix broken ESpec handling in data1 module.
2499 SGML reader parses comments and makes them part of the data1 tree.
2501 Added several type casts so that YAZ compiles as C++ code.
2503 ZOOM didn't handle PDU encoding failures properly.
2505 Added more Bib-1 diagnostics (approved extensions).
2507 GNU configure: better check for iconv.
2509 More portable use of accept, getpeername. Check for socklen_t. Use
2510 int/size_t if socklen_t is not defined.
2514 PQF parser rejects bad queries - including those with extra
2515 characters in them. PQF parser used to silently ignore that.
2516 Cleaner API for PQF added, which allows you to get detailed
2517 error information for bad queries (see yaz/pquery.h).
2519 Fixed bug in ZOOM_record_get for type "database".
2521 Implemented mini iconv library supporting conversions between
2522 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2524 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2526 --- 1.8.9 2002/08/20
2528 Fixed ZOOM C record cache so that preferredRecordSyntax and
2529 elementSetName is used to check for already fetched records.
2531 --- 1.8.8 2002/08/02
2533 Added three members in bend_initrequest structure to facilitate
2534 character set negotiation.
2536 Fixed a bug in frontend server that could cause indefinite
2537 loops under rare conditions.
2539 Revised character set utilities (charneg.h) so that encoding
2540 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2542 For PQF, directive @term <type> sets term type for Scan/Search.
2543 Here <type> is general, string, numeric, null. The term type
2544 is inherited - just like @attr.
2546 New call odr_set_charset that sets character set conversion for
2547 international-strings on a ODR stream. Prototype is:
2548 int odr_set_charset(ODR o, const char *to, const char *from);
2549 The InternationalString is still represented as C string in YAZ
2550 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2551 won't). On the protocol level, you can use any encoding.
2553 Support for UNIX sockets in ZOOM.
2555 Solaris recv sometimes returns errno == ENOENT. It is treated as
2556 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2558 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2559 both client and server. Code by Morten Bogeskov.
2561 --- 1.8.7 2002/05/22
2563 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2564 that they can be used directly from Visual Basic. You must recompile
2565 your windows APP if you're using ZOOM.
2567 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2568 Commands "lang" and "charset" sets language and character set respectively.
2569 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2570 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2572 Attributes from multiple CCL fields may be OR'ed rather than merged
2573 using directive "@field or". Fields are still merged by default -
2574 equivalent to "@field merge".
2576 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2579 Fixed bug in zget for parameter ExtendedServicesResponse.
2583 --- 1.8.6 2002/03/25
2585 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2587 Client displays USR.1:SearchResult-1 (hits per term).
2589 Additional Search Info for search in Generic Frontend Server.
2591 Fixed CCL parsing of "field=s".
2593 WIN32 installer - using the excellent NSIS software from nullsoft.
2595 Fixed CCL parsing of "field = - <number>".
2597 Added function yaz_marc_decode that decodes MARC for line mode
2598 display or XML (similar to that used by JZKit).
2600 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2601 Z39.50. But ISO/ILL was, however.
2603 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2604 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2606 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2607 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2609 --- 1.8.5 2002/02/03
2611 New YAZ client features: Command completion and new commands:
2612 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2613 Code provided by Jacob Poulsen.
2615 New call oid_trav, that visits all registered OIDs via callback.
2617 Function ZOOM_record_get now returns const char pointer rather than
2618 void pointer. It saves a lot of type casts.
2620 For YAZ client, command "auth" now allows you to set authentication
2621 in IdPass style. It is enabled when three tokens are given - order
2622 is user, group and password.
2624 Fix memory leaks in MARC record handling for ZOOM.
2626 New option for YAZ client, -k <kilobytes> that sets
2627 maximum record size. Similar to -k option for generic frontend
2628 server and yaz-ztest.
2630 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2632 Prefix query parser reports "fail" when bad attribute set is given.
2634 Fix in MARC decoder. Proximity logging. Fix for attribute set
2635 in scan handler for server. Patches by Shigeru Ishida.
2637 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2640 Configure option --with-openssl=<dir> now works when a directory is
2641 specified. Patch provided by Morten Bogeskov.
2643 New option for YAZ client, -u <auth>, that sets authentication.
2645 ZOOM fix: error information was sometimes "missing", since error
2646 was cleared/reset too when it shouldn't.
2648 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2650 --- 1.8.4 2002/01/04
2652 Scan for ZOOM API. New object ZOOM_scanset. New functions
2653 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2654 ZOOM_scanset_destroy.
2656 New ZOOM function, ZOOM_connection_last_event, that returns type
2657 of last event (such as "receive data", "send data", "apdu received",
2660 New ZOOM option, schema, that specifies schema for retrieval.
2662 New CCL feature. Qualifiers can be aliases for one or more
2663 other qualifiers (if more than one is given, OR is used).
2665 ZOOM uses named result sets if target supports it.
2667 Two new YAZ client commands: . (dot, which sources a script of YAZ
2668 client commands), and ! (to execute shell command.). Implemented
2671 Working on Debian packages.
2673 --- 1.8.3 2001/11/19
2675 YAZ client enables named result sets only if target supports it.
2677 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2679 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2680 with key="host" to get same result.
2682 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2683 Function Z3950_resultset_record(s) returns references to records
2684 "owned" by resultset. To become owner use Z3950_record_clone.
2686 Function z_ext_record handles Extended Services. Thanks to
2689 --- 1.8.2 2001/11/12
2691 CCL Parser fix: ignore token comma when dealing with and-lists.
2693 Documentation updates for COMSTACK.
2695 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2696 Changed prototype Z3950_records. For some functions, int parameters
2697 were changed to size_t.
2699 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2702 New MARC decode/display function, marc_display_exl, which properly rejects
2703 non-ISO2709 records. YAZ client uses it.
2705 --- 1.8.1 2001/10/29
2707 Fix bug: local attribute set wasn't set correctly in PQF strings.
2711 * Old Z39.50 codecs no longer supported.
2713 Added ZOOM C binding. See http://zoom.z3950.org/
2715 Renamed states for COMSTACKs to avoid confusion with events.
2717 Implemented cs_look and proper cs_rcvconnect.
2719 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2721 Configure detects POSIX threads on OpenBSD.
2723 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2724 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2726 When error is returned from present handler, non-surrogate diagnostic
2727 is returned in present response (and fetch handler is no longer called).
2729 * Minor adjustments to pquery parser (PQF). Token characters may be
2730 escaped by using backslash (C-style).
2732 PQF parser allows string attribute values to be specified. For @attr,
2733 non-numeric characters after the equal-sign are treated as strings
2734 (e.g. @attr 9=title).
2736 CCL trunction character may be defined (@truncation in file)
2738 * function zget_ExtendedServicesRequest sets waitAction to
2739 waitIfPossible (was wait).
2741 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2744 CCL operator names may be set in field definition files (CCL_bibset).
2745 See ccl/bib1 for an example.
2747 Fixes in ASN.1 compiler for C++ compatibility.
2749 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2750 and "op_or" to avoid conflict with C++.
2752 Fixed problem with GNU readline detection on Redhat 7.0.
2754 Added step-size for Scan backend handler.
2756 Fixed bug that made the frontend server crash when no attribute
2757 set was specified for scan.
2759 Front-end server automatically switches to original working directory
2760 when installed as an NT service. Previously -w had to be specified to
2763 Added extended attributes for retrieval module (data1), so that data1
2764 records carry d1_readXML/SGML attributes. d1_read also supports
2765 null-data rules ( <tag/>)
2767 On UNIX when POSIX threads are available, a separate library libyazthread
2768 is created. Programmers should link with that library and the yaz library
2769 when using threads. The reason for the split was that some applications
2770 on Linux, such as Apache, doesn't work well when using shared objects that
2773 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2774 (or any frontend server) in SSL mode by specifying ssl: followed by
2775 address. Only tested on UNIX.
2777 Added feature for CCL module. Virtual structure s=al or s=ol generates
2778 and-list and or-list respectively instead of phrase search.
2782 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2783 log_mask_str. This was done to avoid name conflicts with other libraries
2784 (such as other PHP extensions).
2786 Added raw OID member for preferred record syntax (request_format_raw)
2787 and returned record syntax (output_format_raw) for backend fetch method.
2789 Config file yaz-config now accepts options so that it returns specific
2790 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2792 Shared library support for UNIX using GNU libtool.
2794 * Modified backend interface. Request/Response struct's replaced by
2795 one read/write C struct. For example bend_fetchrequest and
2796 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2797 Every handler - even search has to be registered in bend_init
2798 handler. This means that the YAZ library no longer refers to
2799 external functions and it makes it possible to make the whole
2800 thing a single DLL/SO.
2802 Added Segment handler for backend server.
2804 Added Zmbol/Zebra administrative functions to YAZ client.
2806 Threaded frontend server on UNIX (when POSIX Threads are available).
2807 Starting the server with option -T enables multi-threading.
2811 Added configure option --enable-comp/disable-comp to control use
2812 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2813 located in sub directory asn.
2815 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2816 in ${exec_prefix}/bin along with the other programs yaz-client and
2819 GNU automake used to maintain makefiles.
2821 Added several OID's.
2823 Changed retrieval module so that we can load records with no abstract
2824 syntax defined. Tagpaths in these records are fully composed of string
2827 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2831 On UNIX, the generated makefile now supports a proper 'make install'.
2832 The prefix can be set via GNU configure to set the install location
2833 (default is /usr/local).
2835 * YAZ programs client and ztest were renamed to yaz-client and
2836 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2837 locations, such as /usr/bin,/usr/local/bin,etc.
2839 * YAZ Header files were moved from include to include/yaz. YAZ Header
2840 files are referred to as include <yaz/log.h> rather than <log.h>.
2841 The YAZ include path (-I ..) is therefore the same as before. Programmers
2842 should update their #include statements or use -Ipath/include/yaz
2843 instead. The main motivation for doing this change is that YAZ header files
2844 can be installed in "standard" locations /usr/include,/usr/local/include
2845 without introducing conflicts, since ALL YAZ header files are stored
2846 in subdirectory yaz (under /usr/include for example).
2848 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2849 rather than project/workspace files. We switched because project files
2850 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2853 Changed name of logging function, logf, to yaz_log, to prevent name
2854 clash with some math-log functions. The YAZ header log.h defines logf
2855 to yaz_log (#define) so there should be no incompatibilities by this
2858 Added bend_start/bend_stop handlers for server. These handler are
2859 called on start/stop of server. For windows they are called whenever
2860 a service is started/stopped.
2862 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2863 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2864 in util/yc.tcl. The auto-generated C code structures are, in a few
2865 cases, incompatible with the old decoders. There are differences in the
2866 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2867 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2868 The preprocessor variable ASN_COMPILED is defined when the compiled
2869 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2870 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2871 wish to use the old encoders/decoders you can specify --disable-yc
2874 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2875 version so that it supports both new - and old version of DB Update
2877 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2878 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2879 change. The name parameter can be set to 0 in which no name is specified
2880 for the construction. The macros odr_implicit and odr_explicit sets name
2881 parameter to zero for the construction involved. New macros
2882 odr_implicit_tag and odr_explicit_tag are similar to the others,
2883 except that a name parameter is added. For programmers' that don't use
2884 ODR they probably only need to change the call to z_APDU and z_External.
2886 Added access control facility by interfacing the TCP wrapper library.
2887 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2888 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2889 name of the daemon and enables the access control as specified in
2890 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2892 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2893 den Dool <H.M.vdnDool@kub.nl>.
2895 Added reference ID parameter to most functions in server API - refer
2896 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2898 Changed name of ccl library to libccl.a (was ccl.a).
2900 Fixed bug in decoder for Explain (Category TargetInfo).
2902 Added support for GNU readline in client. Thanks to Jacob Poulsen
2903 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2905 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2906 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2907 IMPLEMENTATION! This change was made to the development version before
2908 the ZIG decided to retract the amendment. If any users MUST be
2909 compatible with the original Update definition, PLEASE CONTACT US, and
2910 we will include a separate definition corresponding to the old Update
2911 ES. Note that because of the change to the ASN.1 of the
2912 TaskPackageRecordStructure we cannot define a single structure that
2913 will support both versions.
2915 * Added const modifier to buffer parameter for some ODR/BER encoding
2916 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2917 completeWAIS, odr_dumpBER.
2919 Fixed bug in client.c which caused a crash when a scanResponse didn't
2920 contain positionOfTerm.
2922 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2923 * will cause an error in a client if a non-YAZ target sends both a
2924 * list of Scan entries and non-surrogate diagnostics.
2926 Retrieval module enhancements. Tag sets may be typed in the reference
2927 to it. From the .abs-file the "tagset" directive takes a third optional
2928 integer type for the tag set referenced. From a .tag-file the "include"
2929 directive takes a third optional type as well. The old "type" directive
2930 in the tag set itself is still recognized but acts as the default type
2933 Backend interface change. Individual Scan terms returned from bend_scan
2934 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2935 in include/backend.h.
2937 Retrieval module enhancements. Multiple tag sets and attribute sets may
2938 be specified in abstract syntax specs. Revised the error/warning for
2939 logging messages reported by the retrieval module when reading the
2942 Object Identifier system (oid_..) changed. The API is backwards
2943 compatible but the oid-routines now allocates new OID's when needed.
2944 Raw OID's may be specified in oid_getvalbyname.
2946 YAZ now uses GNU configure to generate Makefile(s).
2948 * Minor changes in some of the member names of DeleteResultSetRequest and
2949 DeleteResultSetResponse. See include/proto.h.
2951 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2952 and added member 'languages' in TargetInfo (which was missing).
2954 Changed the way attribute sets are handled in the retrieval
2955 module. These are now cached, just like the abstract syntaxes
2958 Changed YAZ so that it links with compiled ASN.1.
2960 Added Explain-schema definitions and mapping routines. The following
2961 Explain categories have been implemented: AttributeDetails,
2962 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2964 Fixed minor bug in Windows version of Server Library.
2966 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2968 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2970 Added EXTERNAL: UNIverse Resource Report (non-standard).
2972 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2973 ENUMERATED and SET OF.
2975 * Added 'const' to some of the char pointer arguments for the
2976 functions, data1_read_node, data1_getelementbytagname,
2977 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2980 Fixed bug in data1_insert_taggeddata - the last_child member of
2981 parent wasn't initialised.
2983 * Changed data1_read_record and data1_read_node so that the supplied
2984 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2985 doesn't refer to any parts of the "SGML"-buffer.
2987 Fixed bug in server library (Windows version of statserv_remove).
2989 * Changed code so that it compiles as C++. The type definition
2990 of Odr_fun which is a member of Odr_arm was changed. The result is,
2991 that an explicit typecast is needed for the fun pointer when
2992 using Odr_arm - as in:
2993 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2995 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2997 Implemented the new structured date and time definition as approved
2998 by the ZIG. Added schemaId element to the specificTag in Espec-1
2999 (also approved at the last ZIG). Thanks to RVDM.
3001 Added some Object identifiers (RVDM).
3003 Changed the Update Extended Service (RVDM).
3005 Added command "refid" to client which specifies referenceId for
3006 the following requests.
3008 Implemented extended service handling for server. See ztest.c
3009 for an example as well as backend.h. New handlers are registerd
3010 in the Init handler.
3012 * Changed interface for sort in server.
3014 Added new members to statserv_options_block. It allows a server
3015 to read options from another source than just the command line. Thanks
3016 to Charles Woodfield.
3018 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3019 renamed to zboolean. Some C++ compilers complained about the name.
3021 Minor changes to gils.abs. Added index 's' (sort) on title
3022 and date/time-last-modified.
3024 --- 1.4pl2 1998/1/30
3026 Fixed bug in server library regarding inetd mode (-i). This bug
3027 was introduced by release 1.4.
3029 --- 1.4pl1 1998/1/29
3031 Added sort facility in client and backend server interface.
3033 Fixed problem with dependencies in Makefile(s).
3035 Fixed bugs for encoders/decoders of extended services and
3038 Implemented sub-tree feature for schemas. Sub-trees are
3039 referenced in *.abs-files. See explain.abs for an example
3040 of the use of this feature.
3042 Modified bib1.att; local attributes for ANY didn't include
3043 ANY itself (only affects use of the retrieval module).
3045 Fixed bug in plain SGML reader in function data1_read_node:
3046 tags with prefix "var" was incorrectly interpreted as variants.
3048 Added feature "sub-schemas" to enable references to - and definitions
3049 of - group of elements.
3051 * Removed member parent from type data1_element (in data1.h).
3053 Implemented function odr_nullval() that returns the value of
3056 * Removed member num_children from data1_node (in data1.h).
3058 Made NT service interface part of the server library. The
3059 function statserv_main uses the NT service when required and
3060 calls the statserv_start / statserv_close routines.
3062 Routine zget_SearchRequest and zget_PresentRequest fills
3063 resultSetName/Id member with "default" instead of "Default".
3065 Fixed memory leak in server. Request queue member wasn't freed.
3067 Fixed nmem_exit so that memory is freed.
3071 Revised the CCL parser utility to be thread safe.
3073 Added function, oid_ent_to_oid, to replace the function
3074 oid_getoidbyent, which is not thread safe.
3076 * Added nmem_init and nmem_exit to initialize and release
3077 NMEM resources. Function nmem_init should be called once in the
3078 initial thread before NMEM/ODR is used. statserv.c and client.c
3079 have been changed accordingly. The change was necessary to make
3080 NMEM thread safe. The NMEM memory pool is shared amongst threads
3081 in a process. Unix-based applications will still work fine without
3084 Added NT Services interface for the the Z39.50 (statserv) Server.
3085 Refer to the ztest.c source on the usage.
3087 Windows 95/NT port using MSVC5.0. Project files are included in the
3090 * Defined new 'global' handle for the retrieval (data1) system. The
3091 new handled, data1_handle, describes the state of the data1 system.
3092 This handle is passed as first argument to virtually all
3093 data1 related routines. The functions data1_create and data1_destroy
3094 creates and destroys a data1 handle respectively.
3096 Added ODR encode stream member to all backend request structures
3097 init, search, scan etc. This stream should be used to allocate all
3098 memory used for the response when thread safe operation is needed.
3100 Changed the comstack utility, cs_addstr, to be thread safe. The
3101 returned hostname string returned by the function is now part the
3104 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3105 function. The cs_straddr takes a COMSTACK handle as argument, so this
3106 function must be used after cs_create and before bind/connect.
3107 This function is thread safe.
3109 Moved test server to 'ztest' directory - generic server code still
3110 in 'server' directory.
3112 Made prefix query (pquery.c) utility thread safe.
3114 Added new function modifier YAZ_EXPORT to 'export' public DLL
3115 functions when using windows (see include/yconfig.h).
3117 Added definitions to the OID database (util/oid.c) (RVDM).
3119 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3121 Added call to ccl_rpn_delete in client program.
3123 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3124 release of RPN structure.
3126 Added support for C++, headers uses extern "C" for public definitions.
3127 With input from RVDM.
3129 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3130 Thanks to Ronald van der Meer (RVDM).
3132 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3134 Added support for private extensions to the OID database
3135 (oid_setprivateoids()). Thanks to RVDM.
3137 Added optional, physical ANY (key replication)
3139 Fixed null-reference problem in GRS-1 output filter.
3141 Proximity operator added to Prefix Query Format (PQF).
3143 In test client command "base" accepts multiple databases.
3145 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3149 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3151 Smallish bug-fixes in the new encoders/decoders (explain).
3153 Bug fixed in DeleteRequest.
3155 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3157 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3159 Added SOIF syntax (using private OID for now) to retrieval module and client.
3161 Added Update extended service.
3163 Added SearchResult-1 additional info structure.
3165 Added optional CCL (ISO8777) interpreter as separate module. Available
3168 --- 1.2 1996/6/10 (1st anniversary release)
3170 Added Summary record syntax. Lightly tested.
3172 Added OPAC record syntax. Untested.
3174 Added ResourceReport service encoders/decoders. Untested.
3176 Fixed bug in z_Unit - wrong tagging on unitSystem.
3178 Fixed bug in the DiagRecs decoder.
3180 Added options for max PDU size and session timeout to frontend-server.
3182 Added documentation of query-language parsers and other supporting utilities.
3184 [frontend-server] Added Attribute set to the bend_scanrequest API.
3186 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3187 surrogate diagnostics were generated.
3189 [retrieval] Allow multiple local values for attribute.
3191 [retrieval] Allow multiple attributes per element in .abs files. index type.
3193 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3195 --- 1.1pl2 1996/4/10
3197 Minor changes, mostly specific to Zebra's requirements (retrieval)
3201 Repaired bug in frontend server when running multiple listening
3202 endpoints in dynamic mode.
3204 z_External() now won't break if a known, ASN.1 value comes encapsulated
3205 in an octet-string. The value will pass through unmodified in an Odr_oct.
3207 Added a bit of code to the demo client to decode & display
3208 ASN.1-structured records represented in the octet-aligned branch of
3209 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3211 Added z_ext_getentbyref() to the ASN module. Doc updated.
3213 * Completed the SCAN definition in the ASN module. This may break SCAN
3214 code based on older YAZ-versions at compile-time. The fix is easy -
3217 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3218 under the SCAN definition. Remember to initialize this, server-people.
3220 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3221 that this does not extend to ODR and ASN.
3223 Comstack allows insertion of established socket (primarily for
3224 inetd-operation of servers). Doc updated.
3226 Front-end server can now start from the inetd in TCP mode. Doc
3229 --- 1.0pl4 1996/1/24
3233 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3234 the rank and record number.
3236 Adjustments to the frontend server.
3238 Fixed diagnostic BER dumper. It ignored the file argument.
3242 Various changes to retrieval module.
3244 Changed the union discriminators of the protocol files from enums to
3245 ints paired with #defines.
3247 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3250 *Changed operator in the RPN structure to 'roperator', again to avoid a
3253 Fixed problems in Explain decoders/encoders.
3255 --- 1.0pl2 1995/12/6
3257 Memory bug in log module fixed.
3259 --- 1.0pl1 1995/12/5
3261 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3263 Bug in Explain DatabaseInfo module fixed.
3265 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3269 The shift to v1.0 signals that we now consider the *core* functionality
3270 of YAZ reasonably stable (the core being more or less equivalent to
3271 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3272 tested (Explain not at all - though that will happen soonish).
3274 Minor changes to code to support Windows port.
3276 Various minor changes after we're getting to use GRS-1 & co. more.
3278 Added Espec-1 format.
3280 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3281 of the protocol and it cannot be selected when encoding (maps into 'string'
3282 when decoding). Needed to talk to some servers.
3284 Demo client can request simple element set names.
3286 Added Diagnostic Format encoders/decoders.
3288 Added simple Close handling to frontend server (no hooks for resource
3289 reporting yet), and demonstration client.
3291 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3293 --- 1.0b3 1995/08/24
3295 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3296 handled incorrectly when records were requested in the searchResponse. This
3297 will only affect you if you use the frontend-server.
3299 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3300 Test-client will ask for and print GRS1. Ztest will return dummy records
3303 Added Explain encoders/decoders to the service-level API. Untested.
3305 Added Extended Services: Item Order encoders and decoders to the Service-
3306 level API. Untested. We could use a recent copy of the pertinent bits
3307 of the ILL protocol to add those bits.
3309 Added diagnostic format 1 encoders/decoders to the service-level API.
3312 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3313 odr_cons.c, which causes a more correct output.
3315 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3316 was always set to 0 when no records were requested in the searchRequest.
3318 * Added better external-handling. This shouldn't harm old code that
3319 *encodes* externals. It can break code that looks for a
3320 'single-ASN1-type' representation, since those types that are known
3321 are now decoded immediately. Look at the SUTRS sample code in
3322 seshigh.c and client.c. Documentation updated.
3324 Handling of structured records in bend_fetchresponse. Length -1 marks
3325 structured record, type is deduced from format field.
3327 --- 1.0b2 1995/06/27
3328 Fairly quick maintenance release to add SUTRS support.
3330 Fixed handling of SUTRS records in the demonstration client.
3332 * Added format field to the bend_fetchrequest and bend_fetchresponce
3333 structures of the backend API (frontend server). When the record is
3334 returned, the value of the format field is mapped to an OID. The
3335 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3336 of the record. The special value VAL_NONE in the bend_request means
3337 that no specific format was requested by the client. Documentation
3338 updated accordingly. Test server (ztest) will return a fixed dummy
3339 SUTRS record if your client requests SUTRS.
3341 Documentation updated accordingly.
3343 You can now set external libraries and RANLIB support in the top-level
3347 First public release.
