3 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
4 made available as a utility function, declared in <yaz/logrpn.h>
6 rpn2cql_structure() supports proximity nodes (except that the Type-1
7 proximity node's "exclusion" binary is ignored, as there is no way to
8 express that in CQL). Fixes bug #4564.
12 Fix SEGV that could occur if set command of zoomsh was given without
15 Fix SEGV that could occur if unsupported transport was given for
16 COMSTACK - say https (when SSL was unavailable).
18 Build yaz-url on Windows too.
22 New utility to get web content. Header is url.h. A command line tool
23 yaz-url is part of the distribution and packages.
25 Fixes for SSL COMSTACK (when gnutls is in use).
27 New functions yaz_base64{encode,decode}. Header is base64.h.
31 ZOOM C includes HTTP response buffer as additional info if it fails
32 to decode the SRU response.
34 Make wrbuf_json_puts available.
38 zoom: throw diagnostic for invalid value for option "sru". Before a
39 bad SRU request was sent.
41 Adding new utility wrbuf_vp_puts.
43 Add cclxmlconfig.obj to win/makefile. It was missing completely.
47 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
48 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
49 redirect was used at the same time.
51 MARC line mode decoding: be less picky about length given - first
52 5 digits of header that is.
54 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
56 Changes to decoding of SRU records: a record with recordPacking=xml is
57 modified with a new root element <yaz_record> if the recordData contains
58 multiple children elements. This is to make the record XML parseable
61 RPN to SOLR conversion: encode special characters.
63 Generic Frontend Server: fix uinitialized member, stepSize.
67 Fix a bug in SRU decoding of records.. The database records stored
68 had un-initialized memory, but it would only be seen with yaz_record_render
71 Fix a bug in ccl_qual_dup introduced in 4.2.3.
75 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
79 Add new utilities to convert from CQL to CCL . These utilities have
80 prefix cql_to_ccl defined in cql.h.
82 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
83 lead to memory heap corruptions when ICU utilities were in use.
87 Make compilation work without Libxml2.
89 yaz-client: remove redundant blanks in display of searchResult-1 term
94 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
95 resulting CQL node (tree) in a new node CQL_NODE_SORT.
97 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
98 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
99 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
100 Note that the CQL sortby spec is only converted when the GFS is already
101 converting from CQL to RPN (cql2rpn element).
103 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
104 specify whether to collapse delimitors or not. The existing nmem_strsplit
105 do collapse (collapse parameter = 1).
107 Windows installer: For NSIS, set InstallDir depending on x86/x64.
109 Rename internal func yaz_use_attribute_create. While non-static, this
110 function is not declared in a public header.
114 Add -lCrun when linking with ICU on Solaris.
116 More quicks character set conversions for OPAC records.
120 fix problem with record_render: records were converted (character set
121 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
125 SRU: add methods for handling DADS SRU-proxy facets.
127 Separate OPAC record character set for ZOOM_record. yaz_record_render
128 allows a character set given as charset=from/opacfrom,to where 'from' is
129 the character set of a bibliographic record, 'opacfrom' is character set
130 of OPAC record and 'to' is the target character set.
134 yaz-client: show may XML format records. Command show followed by 'format'
135 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
138 src/stemmer.c: Avoid using unnamed union. It is not supported by some
141 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
144 Update yaz.spec to operate on both SLES11 / Centos 5.5.
146 RPM: Release includes 'indexdata' name. Use indexdata in release name so
147 this package can be distinguished from other vendors.
149 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
150 as determined by configure
152 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
154 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
155 returns no error and no record, the present request is considered
156 partial (only a subset of the records could be returned by backend), and
157 so it is appropriate to set Present Status to partial-4.
161 Move yaz-config man pages to section 1.
163 More documentation about SOLR.
165 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
166 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
167 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
168 peers on some Linux systems. However, in general that does not work
169 so YAZ can not rely on that to work. Debian changed behavior in this
170 respect from Debian lenny to Debian squeeze (still testing as of Oct
172 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
174 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
178 Fix yaz-config output: echo_source not set correctly by configure.
182 SOLR WebService support for yaz-client and ZOOM.
184 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
186 --- 4.0.12 2010/08/17
188 Z39.50 facet support. Facet specifications are passed for search in
189 other-information with ASN.1 as defined in facet.asn and OID
190 .10.1000.81.5 . Facets are expressed as an Attribute list as known
191 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
192 3 is limit (number of entries to get in response). yaz-ztest returns
193 dummy facets if a client asks for them.
195 --- 4.0.11 2010/07/09
197 CCL fixes: bug 2895 and bug 3539.
199 GR1-display: add comma in display - was removed by mistake in
202 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
204 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
206 --- 4.0.10 2010/06/18
208 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
209 result set from a connection. The result set will be on its own
210 thereafter; no operations on it will perform retrievals from a target.
211 Only cached copies are returned.
213 ZOOM C:fix case for HTTP servers responding with Connection:close.
214 Ensure that if there is a current task it is resumed (like fetching
215 more records in a result set) . Bug #3484.
217 PQF parser: use odr_atoi for Odr_int (not atoi)
219 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
220 values that contain any non-digits are treated as string attributes
221 (previously decoding only checked for leading character ([0-9]). PQF
222 encoding: attribute string values are not surrounded by double-quotes.
226 New utility for managing threads - thread_create.h.
228 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
229 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
230 but YAZ' implementation do.
232 Fixes for yaz_cond-functions on Windows 7.
234 DLL export more symbols.
236 zoomsh: show record do NOT render opac.
238 Remove *.la files from Debian and RPM packages.
242 Debian package libyaz-dev depends on libgnutls-dev again (was
243 removed in YAZ 4.0.6, but due to Libtool it is still needed
244 even though yaz-config do not list libgnutls libs).
246 ZOOM: Use only one WRBUF for returning string results for
247 ZOOM_resultset. Reduces memory usage for ZOOM in general.
249 ZOOM: ZOOM_connection do not use a shared pointer to
250 ZOOM_resultset after ZOOM_resultset is destructed by
251 user. Reverts to YAZ 4.0.4 behavior.
255 record-conv: fix problem with at least one XSL conversion -
256 due to probably incorrect usage of XML XSL documents.
260 Fix yaz-config for static mode and the use of SSL (gnutls).
264 Forward decl timeval struct in mutex.h and gettimeofday.h.
266 yaz-config: fix 'static' mode linking.
270 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
271 are wrappers for pthreads or Windows. For Windows these are put in
272 a separate DLL: yaz_cond4.
274 libyaz.la (whole source) is compiled with thread. If thread support
275 is enabled enabled, all source of YAZ is compiled with treading support.
276 This allows core utilities such as yaz_log to use thread facilities.
277 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
278 thread utilities. This commit moves mutex utilities (mutex.c) from
279 libyaz_server.la to libyaz.la.
281 yaz-json-parse displays leading text until error.
285 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
286 patch from Giannis Kosmas.
288 SRU: no longer URL encode SRU database. The URL for an SRU server is
289 a URL and such is alreeady encoded - at least when given with leading
290 http:// or https://. This reverts behavior to YAZ 3.0.50.
292 Support for new MARC XML notation TurboMARC which like MARCXML is a
293 complete representation of MARC/ISO2709.. This one, however, is more
294 compact and allows for faster processing with XSLT. TurboMARC can be
295 used in the marcdisp.h API, from the yaz-marcdump utility and from
298 yaz-ztest can be configured - via the database - to perform certain
299 delays when it performs operations search, present and single record
300 fetch. This allows testers to make yaz-ztest act as a real or even slow
301 Z39.50 server. Refer to the yaz-ztest man pages for details.
305 wrbuf_destroy allows NULL WRBUF passed to it.
307 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
309 Add ZOOM_connection_close.
311 No fixed size buffers for ZOOM shell - bug #3257.
313 tstodr: make it work on s390 platform.
315 New icu iterator-functions. The new icu_iter-functions makes it possible
316 to use ICU chains from many threads.
318 yaz-client: better syntax check for show command.
322 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
325 New simple local-file XML include facility which allows file glob-patterns.
326 Refer to yaz/xml_include.h.
328 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
331 ZOOM_record_get supports new parameter "format" which makes it format XML
334 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
335 JSONText in ECMA-262) is JSONValue, not JSONObject.
339 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
340 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
342 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
343 POSIX/Unix builds .so with major version 4.
345 Remove old LOG_-defines from log.h. They have been obsolete and
346 undefined by default for the last 5 years.
348 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
350 GFS: Remove socket (int *fd) from search_rr handler. The socket
351 descriptor ptr is a facility that allowed a search handler to supply
352 a socket which would serve as a callback - when search was complete.
353 This facility has now been in use for years.
355 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
356 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
357 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
358 returns 'const char *' rather than 'char *. The returned string is
359 read-only and should not be modified by applications. COMSTACK cs_close is
360 now a void function - it no longer returns int. No applications check for
361 the value and the implementations has always returned 0.
363 ZOOM: use size_t for scan hit counts and str size. Functions
364 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
365 occ (hit count) and len (string length) are now of type size_t pointer
366 rather than int pointer. This is to be able to represent large hit counts
367 and to also just to use the proper type for string length (strlen result).
369 New JSON parser. Refer to include/yaz/json.h .
371 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
372 Used to be int in some cases. Many wrbuf_-functions used to return an int
373 indicating some length.. These return values were never used. And so they
376 ODR: odr_malloc, odr_total now takes size_t for size.
378 clone_z_type: fix leak; occurred for encoding failures.
380 --- 3.0.52 2009/12/03
382 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
383 bug was introduced in 3.0.51.
385 --- 3.0.51 2009/12/02
387 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
389 tcpip comstack: fix leak for getaddrinfo.
391 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
392 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
393 Decoding of SRU "path" database is performed by private function
394 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
395 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
397 yaz-client: honor base command for SRU. Change when database setting
398 is applied for SRU and ensure it is kept when a connection is reset.
399 Change also the way errors are displayed or SRU (decoding of packages).
401 --- 3.0.50 2009/11/02
403 Add support for extra request / response data for SRU codecs and GFS.
404 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
405 for extra data response buffer and length. For the GFS, both request
406 and response data (XML) is carried in extra_args and extra_response_data
407 for the search handler. Patch by Ko van der Sloot.
409 ZOOM: For queries that cannot be converted to the specified rpnCharset,
410 ZOOM now returns a diagnostic on the client-side ('invalid query' /
411 10010). This fixes bug #2113.
413 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
414 cmdfile included a 'quit' command that would result in a memory violation.
416 --- 3.0.49 2009/10/01
418 Make a number of functions defined in xmlquery.c static. These have
419 never been declared in a public header file (yaz/xmlquery.h) and was
420 made public by mistake.
422 Improve speed of character conversions (iconv utilities). This makes
423 conversions from MARC-8 faster.
425 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
426 unless type desired is "raw". This will prevent type "xml" from
427 returning ISO2709 .. Which obviously can not be XML parsed.
429 Fix memory leak in ZOOM that would occur if option apdulog was used
430 on a re-used connection.
432 Frontend server logs HTTP requests.
434 Frontend server now sends Z39.50 close when it times out (sesssion has
435 been idle for too long). Versions 2.0.30 and earlier also sent close.
436 But due to a mistake this was disabled in all versions after that, i.e.
437 the server would just close the socket immediately.
439 yaz-client emits a better message when receiving an unrecognised
440 userInformationField.
442 Skip zero-length subfields when decoding ISO2709. This rare case happens
443 if a record has two FS characters in a sequence. Without this patch
444 there would be a reference beyond char array in using_code_len fragments
447 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
449 --- 3.0.48 2009/08/28
451 The show command offered by the zoomsh command now takes a 3d optional
452 parameter type which is what is passed to ZOOM_record. If the type
453 argument is omitted, "render" is used.
455 RPN to CQL conv may use USE string attributes (bug #2978).
457 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
459 --- 3.0.47 2009/07/08
461 Function yaz_xml2query allows a diagnostic element in the PQF XML
462 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
463 code and additional info respectively.
465 The BER BOOLEAN is now the integral type Odr_bool which still happens
466 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
467 typedef'd to Odr_int. This is still an integral 'int', but it may be
468 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
469 ASN-1 compiler as well as programs has been updated to use the new types.
471 --- 3.0.46 2009/06/08
473 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
474 only the bibliographic record was rendered. For type=opac, an OPAC
475 record is only returned if it is present.
477 iconv: small fix for encoding of advancegreek.
479 yaz-client: avoid double display of SRU/SRW records (bug #2798).
481 yaz-client: option auto_reconnect=on really reconnects.
483 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
485 server: avoid null ptr ref for for yaz_poll errors.
487 build: fix RPM build for RHEL 5.3.
489 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
491 --- 3.0.45 2009/03/31
493 Fixed bug #2709: TCP connect returns Invalid argument.
495 Fixed compilation for mingw.
497 Honor charset for raw records (ZOOM_record_get).
499 Fixed use of errno for threaded mode that was seen on Solaris 10.
501 Fixed argument passing with blanks in value for Windows Service.
503 Disable YAZ' own log rotate by default (no 1 GB limit).
504 The variable l_max_size which specifies the log file limit is set to 0
505 (DISABLED): This is due to the fact that YAZ is most often deployed using
506 logrotate. Also YAZ can not perform log rotate because of unsufficient
507 permissions (setuid).
509 --- 3.0.44 2009/02/17
511 List supported encodings in man page for yaz-iconv.
513 Fixed missing SSL libs for --libs output
515 Re-established OID record syntax application-xml. Nobody should use it
516 but we don't want to change soname because of this symbol being absent.
518 --- 3.0.42 2009/02/02
520 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
522 Added member named_result_sets for init handler struct for the GFS. This
523 allows a server to disable named result sets.
525 Removed OID record syntax application-xml.
527 Added support for rule-based transliterator for ICU wrapper of YAZ.
529 Fixed bug #1902: yaz-icu XML output.
531 Make YAZ checks Emacs friendly.
533 BITSTRING value shows value. Bug #2346.
535 ISO2709 decoding: skip control characters from indicator data.
537 Omit sort key by default in yaz-icu's output.
539 Allow combined single char options (again) for YAZ' options function.
541 Utility yaz-marcdump got option to display YAZ version (-V).
543 Allow YAZ to use ICU 3.4.
545 Added new ICU test case which illustrates removal of diacritics.
547 --- 3.0.41 2008/12/29
549 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
551 --- 3.0.40 2008/12/29
553 For configure, using option --without-xml2 also disables Libxslt/Libexslt
556 Fixed bug #2352: yaz-marcdump crashes for certain record.
558 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
560 Added support for Danmarc2 to UTF-8 conversion.
562 Added support for ISO5426 to UTF-8 conversion.
564 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
565 implementation version.
567 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
569 --- 3.0.38 2008/11/10
571 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
572 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
574 ZOOM C now interprets databaseName option for ZOOM connection as path
577 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
579 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
581 Dummy Libxml2 types no longer defined in headers of YAZ'.
583 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
586 --- 3.0.36 2008/09/26
588 Various ODR chapter fixes.
590 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
592 Added missing source for Windows compilation, mutex.c.
594 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
596 For SRU connections in ZOOM all records up to "count" are now fetched.
598 Fixed crash in generic frontend server (and yaz-ztest) which occurred
599 in Windows due to bad error handling for Libxml2.
601 Added facility for sending arbitrary records (ASN.1 any) using
602 ZOOM C's Extended service update. Patch by Sam Reynolds.
604 New options for ZOOM C's connection, logapdu which makes ZOOM log
607 --- 3.0.34 2008/06/18
609 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
611 --- 3.0.32 2008/06/12
613 Fixed memory violation that could occur when decoding UTF-8. This bug
614 was only present in 3.0.30 of YAZ.
616 --- 3.0.30 2008/06/06
618 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
619 GNU TLS is used by default (if found).
621 yaz-ztest returns OPAC records if a client asks for OPAC.
623 Improved speed of MARC-8 encoding.
625 Added support for lossy and loss-less MARC-8 encoding.
627 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
629 Added new Windows Service wrapper (sc).
631 yaz-client's itemorder command may now send a file.
633 Fixed yaz-marcdump to allow the use of NS prefix for record element.
635 Added new function yaz_log_xml_errors.
637 Allow (but warn) unknown XML attributes in MARCXML parsing.
639 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
641 The UTF-8 to MARC-8 conversion now uses a different set of characters
642 for Greek symbols. Bug #2120.
644 --- 3.0.26 2008/02/21
646 Added yaz_daemon (daemon.h).
648 Fixed bug #2068: pkg-config trouble
650 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
652 --- 3.0.24 2008/01/28
654 Document --with-xml2 option.
656 Added OPAC XML XSD (etc/opacxml.xsd).
658 Allow glob mask for name attribute in retrieval element for the
659 generic frontend server's retrieval facility.
661 Changed yaz_poll_poll to return yaz_poll_except for all returned events
662 except POLLIN/POLLOUT.
664 Fixed error handling in cs_listen. Bug #2037.
666 --- 3.0.22 2008/01/20
668 Fixed version in yaz/yaz-version.h.
670 Fixed bug #2027: Crash when closing connection.
672 Changed configure so that ICU support is only enabled if only ICU
673 and Libxml2 is available (because the ICU chain is XML based).
675 --- 3.0.20 2008/01/15
677 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
678 is built. Only this DLL depends on the ICU runtime.
680 yaz-ziffy is no longer part of YAZ. It is distributed separately by
681 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
683 Changed license of CCL module to 'Revised BSD'. After consultation with
684 remaining members of the original EUROPAGATE consortium, we are re-issuing
685 the CCL module without a separate license. The software was developed by
686 Index Data as part of a research project. The special license was included
687 to help feed usage information back to the project consortium to support
688 project evaluation. At this time, the project consortium has long-since
689 disbanded, and the majority of the original principals have retired. At the
690 same time, we have significantly modified the software during the following
691 years, to the point where very practically no original code remains. To
692 simplify re-use of the software, we have contacted those members of the
693 consortium who could be reached, and agreed to re-issue the module as a
694 proper part of the YAZ package.
696 Tcl scripts uses /usr/bin/tclsh as preferred shell.
698 CQL closer to being version 1.2 compliant. CQL also allows free-form
699 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
702 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
703 bug could make Extended services handling crash in the ZOOM layer. This
704 bug was only present in YAZ 3.0.18.
706 --- 3.0.18 2007/12/19
708 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
711 yaz-marcdump reads and writes collection wrapped records.
713 Handle OPAC for record conversion module.
715 Fixes for ICU wrapper.
717 Allow ICU libs to be controlled with --with-icu .
719 --- 3.0.16 2007/11/12
721 Added yaz_poll which is a wrapper for select/poll. When poll is available
722 and non-buggy, it is used, by yaz_poll . This allows more than 1024
723 sockets to be in use.
725 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
726 functionality through an XML based configuration (ICU chain). This system
727 is useful for search facilities such as Pazpar2 and Zebra that needs to
728 perform tokenization of indexed material. The ICU code in a separate
729 library libyaz3_icu.a.
731 Added HTTP tunnel facility for COMSTACK, bug #1752.
732 This is a facility that allows a Web proxy, such as squid, to tunnel
733 Z39.50 traffic. This facility is "transparent" to must applications
734 using YAZ. It's enabled by using pseudo transport connect: followed by
735 the proxy address, followed by command, then follwed by he regular
736 "virtual" addresss. For example,
737 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
739 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
741 --- 3.0.14 2007/09/21
743 Fixed bad memory reference in ZOOM_record - cuased by member not being
744 initialized. This was a problem only in YAZ 3.0.12.
746 Fixed bug in conversion from MARC to XML: Non-XML characters in control
747 fields were not removed.
749 Changed the way C code is generated from codetables.xml. Made a MARC-8
750 conversion trie for each characterSet section rather than codeTable.
751 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
752 of codetables.xml from Larry Dixson, LOC. Bug #1464.
754 --- 3.0.12 2007/09/12
756 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
757 from ZOOM_record_error).
759 ZOOM C function ZOOM_record_get returns record schema for type="schema".
761 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
763 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
765 Better SRW-to-Bib-1 diagnostic mapping.
767 ZOOM C and yaz-client announces SRU version 1.2 by default.
769 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
772 Fixed in yaz_sru_decode to allow other version than 1.1.
774 --- 3.0.10 2007/08/22
776 Added support for SRU scan for ZOOM.
778 Added support for the use of the older versions or Extended Service
779 Update in ZOOM. To faciliate this, an option "updateVersion" may be
780 set to the version , 1=first, 2=second, 3=third. The third version is
781 what ZOOM C has used so far. And that, obviously, is the default.
783 Added support for CCL queries in Z39.50 queries sent to the GFS (and
784 therefore in Zebra and in SimpleServer-based applications). The new
785 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
786 qualifier file used to transform incoming CCL queries into Type-1 RPN,
787 which is passed into the back-end search callback function.
789 Added support for HTTP Basic authentication in clients: the SRU/W
790 codec encodes the username/password elements of the PDU structure
791 appropriately, and these may be set using the "user" and "password"
792 options in ZOOM-C applications (the same options that are used for
793 Z39.50 authentication).
797 Fixed bug #1208: SSL appears to be broken in ZOOM.
799 Fixed bug #1206: Libxml2 include path weirdness.
801 Added oid_name_to_dotstring.
803 Allow elementSetName to be specified for ZOOM C record update.
805 Allow waitAction to be specified for ZOOM C based for Extended Services.
807 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
808 syntax OID. Bug introduced in YAZ 3 series.
810 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
814 Fixed bug #1157: yaz-client does not read .yazclientrc from current
815 directory. yaz-client now reads commands from file given by option -f
816 if specified; then tries to read .yazclientrc in current directory.
817 Failing that, it reads .yazclientrc from user's home directory.
819 Added support for correlationInfo Note and ID for Record Update via
822 Added yaz-client command querycharset which specifies character set for
823 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
824 (termListAndStartPoint).
826 Charset ISO5428:1984 is an alias for ISO5428-1984.
828 Implemented a way to perform scan in a result set using Z39.50. This
829 is achieved by attaching the result set name in the characterInfo
830 (type InternationalString) of OtherInformation in the Scan Request PDU.
831 The result set is identified in the otherinformation by the new OID:
832 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
833 This allows for scan in result set and faceted search . Zebra did some
834 of this in the APT term using attribute type 8 and value being result
835 set. Using the OtherInformation approach for this is cleaner and easier
836 to work with in proxies and the like. This facility can be used in
837 yaz-client using new command setscan which takes a result set as first
838 argument, start position (APT) as second.
840 Changed decoding of SRU XML packed records to deal with servers that
841 have recordData with XML data with multiple root nodes. Also make
842 comparison for recordPacking case insensitive. Again, one server
843 returns "XML" where others return "xml".
845 For SRU responses allow Content-Type application/xml as well as text/xml.
849 Fixed bug in character set conversion of BER strings. Bug introduced
854 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
856 For OID class, use oid_class consistently.
858 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
861 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
862 character set for bibliographic information interchange". By Giannis Kosmas.
864 Added documentation on new OID API.
868 Changes to generic frontend server interface: added new member
869 'query_charset' for bend_initrequest structure. A backend init handler
870 should set this member to its native character set for query terms.
871 When defined, the frontend server logic will announce this character set
872 to a client if the negotiationModel bit is set by the client. All server
873 implementors are encouraged to specify this. If a backend server does not
874 specify this a warning is issued using yaz_log(YLOG_WARN,..).
876 Added CCL utility to remove terms (stop words) from resulting RPN
877 tree. This is handled by functions with prefix ccl_stop_words_ .
879 New ZOOM C option, "rpnCharset", which allows client-side conversion of
880 terms in RPN queries.
882 Clean-up the CCL API. Moved some internal structures from ccl.h to
883 private header cclp.h. Changed ccl_parser_create so that a Bibset must
884 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
885 This is replaced by ccl_parser_find_str which takes a string instead.
887 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
888 libyaz.la is the core of YAZ except the generic frontend server and
889 does not depend on POSIX threads anymore. libyaz_server.la is the
890 generic frontend server facilities and uses POSIX thread functionality
891 if available. The libyaz.la no longer depends on POSIX threads because
892 the number of global structures is limited. NMEM no longer re-uses blocks
893 between threads ; it simply free's memory immediately but allocates in
894 "large" chunks as usual. We don't expect any performance penalties
895 because of this. The yaz_log system is still using a global log_level so
896 caution must be taken when modifying it with yaz_log_init_.. +
897 yaz_log_mask_str. This, however, should not cause any trouble because
898 these functions are called during initialization of application code
899 anyway. `yaz-config --libs server` returns libs for server applications;
900 `yaz-config --libs` returns libs for non-server applications.
902 New OID database - with public definitions in oid_db.h. Removed old OID
903 database including the head oid.h and definitions such as enum oid_value
904 and struct oident. The new OID database uses the same string names as
905 before but the 'protocol' is gone. There are now only two representations
906 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
907 converts from string to OID; functions with prefix yaz_oid_to_string
908 converts the other way.
910 Change to emit_term() in CQL-to-PQF query translation: when a term has
911 the /regexp relation modifier, do not process it for leading and
912 trailing "^" and "*", which have quite different meanings in regular
915 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
916 write handlers no longer carries a 'last' parameter. This will make
917 yaz_iconv flush "less" characters. A flush is performed by call to
918 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
920 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
921 removed, because function yaz_query_to_wrbuf does the same.
923 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
924 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
926 Deprecated MARC utility functions removed.
928 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
931 Branch split: YAZ_2_1_55_branch
933 --- 2.1.54 2007/03/16
935 Fix to ZOOM-C so that transparent reconnection is properly handled on
936 connections that are in asynchronous mode.
938 Fixed compilation on OpenBSD 4.0.
940 Large strings in GRS-1 records are now properly displayed in yaz-client.
942 Added character conversion support for "advancegreek"; based on patch from
945 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
946 sequence is met. Before the error was not set so it would be unknown.
948 Adjust yaz-marcdump MARC reader so that it skips until record separator
951 --- 2.1.52 2007/03/07
953 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
954 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
955 fd_set structure used as a bitmask for the FDs to be selected on.
957 Using ACX_PTHREAD macro to check for POSIX threads.
959 Fixed have-vsnprintf check.
961 --- 2.1.50 2007/02/23
963 Fixes for configure on BSD. Bug #900.
965 Added snprintf/vsnprintf wrappers for systems that don't have
966 limits (heavens forbid).
968 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
969 created before all previous tasks were completed and removed from the
970 task queue, the new task could be removed by a mistake.
972 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
974 Implemented pass-through CQL-to-PQF conversions. Bug #861.
976 Fixed bug #832: Problem with MARC/charset in yaz-client.
978 Fixed bug #668: save command line history for yaz-client.
980 Fixed bug #830: pkg-config support.
982 --- 2.1.48 2007/01/23
984 Extended ZOOM result set options with two options that may be read by
985 a client: resultSetStatus and presentStatus with values as specified for
987 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
989 Fixed bug #827: Using SSL fails on Debian etch.
991 Fixed bug #826: Weird looking chars for set of MARC records.
993 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
994 that is treated as an ItemOrder with itemRequest being an XML document
995 external. The value of "doc" is the content.
997 Extended the GFS search facility. New member of bend_search_rr
998 'estimated_hit_count' signals that hits is known to be an estmate
999 (higher or lower than real hit count). New member 'partial_resultset'
1000 signals that the search was partial (hit count is lower or equal than
1001 real hit count). For Z39.50, the information is stored in resultSetStatus
1002 member of SearchResponse APDU. For SRU, the information is signalled
1003 via SRU diagnostic 59: "Result set created with valid partial results
1006 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1008 --- 2.1.46 2007/01/13
1010 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1012 Added ZOOM_connection_peek_event.
1014 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1015 the following new functions:
1016 ZOOM_event_nonblock, ZOOM_connection_process,
1017 ZOOM_connection_get_{socket,mask,timeout},
1018 ZOOM_connection_fire_event_{timeout,socket}.
1019 The existing blocking event handler, ZOOM_event, is a wrapper for the
1020 + blocking ZOOM_event_sys_{poll,select}.
1022 Implemented function ccl_xml_config which parses XML version of CCL
1023 configuration (bug #798).
1025 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1027 Added timings utility (yaz/timing.h)
1029 --- 2.1.44 2007/01/03
1031 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1034 Fixed bug #779: Rotation of apdu.log fails.
1036 Fixed for character set conversions:
1037 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1038 Honor G1 set in MARC-8 decoding.
1040 --- 2.1.42 2006/12/17
1042 Fixed bug #775: char conversion does not handle Alternative UTF-8
1045 Implemented function yaz_marc_read_line which parses MARC line format
1046 records. There is a wealth of formats out there. So far, this function
1047 reads line records produced by yaz_marc_write_line.
1049 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1050 more generic and easier to remember(!) options: -i format and -o format
1051 which specifies input format and output format respectively - where
1052 format is one of "marc", "marcxml", "line", "marcxchange".
1054 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1055 does not print anything except warnings for records.
1057 For yaz-marcdump, added support for MARC split into files (-s) with a given
1060 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1061 spec, at http://www.loc.gov/standards/sru/record-update/
1062 This has changed the binary layout of the following structs:
1063 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1064 bend_update_rr . Patch by Ko van der Sloot.
1066 Added GFS utility function bend_assoc_is_alive which returns 1 if
1067 association is still alive (client is connected); 0 otherwise (client
1068 closed connection). This allows busy servers to stop working for
1071 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1072 been a separate piece of software. This version of ziffy has been modified
1073 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1075 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1077 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1078 Client code may now interrogate options such as "init_opt_sort" to
1079 find out whether the server claims to support various options.
1081 --- 2.1.40 2006/11/27
1083 Added utilities yaz_{set,get}_esn to set/get element set name from
1086 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1087 of YAZ and has been so since YAZ 2.1.10.
1089 Implemented ZOOM_record_error which returns error information for
1090 record (surrogate diagnostic).
1092 --- 2.1.38 2006/10/31
1094 Updates for SRU Update by Ko van der Sloot:
1095 1. Changed name from "operation" to "action"
1096 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1097 versions in the code, marked as 'backward compatible'.
1098 3. Added diagnostics for SRU Update.
1100 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1102 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1104 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1106 For GFS, fixed problem with SRU diagnostic 'First record position out of
1107 range' being issued for 0 hits.
1109 zoomtst10 part of Windows Build.
1111 --- 2.1.36 2006/10/13
1113 Implemented yaz_filepath_comp which splits a path into file path
1114 components (required by Zebra 2.0.3+).
1116 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1117 BSD inspired license until now so this should not have any real impact on
1118 anybody. See http://www.opensource.org/licenses/bsd-license.php
1120 Fixed bug #687: Missing log lines.
1122 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1125 Fixed bug #689: SRU diagnostics to be added.
1127 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1128 whether a connection is idle (no more work do do).
1130 --- 2.1.34 2006/10/04
1132 Change type of optval from long to int for invocation of setsockopt with
1133 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1135 Added support for specifying the max log file size for the Generic
1136 Frontend Server. The size is given with option -r.
1138 --- 2.1.32 2006/09/21
1140 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1142 --- 2.1.30 2006/09/17
1144 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1147 Fixed bug in Generic Frontend Server that could cause a server to stop
1148 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1150 For the generic frontend server, the maximum record size is used as maximum
1151 size of incoming packages (SRU + Z39.50). The value until was previously
1152 only used in Z39.50 Init negotiation and, later, in a session controlled
1153 sizes of records returned. This is controlled using -k option. It can be
1154 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1156 --- 2.1.28 2006/09/04
1158 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1161 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1163 New option for yaz-marcdump -lpos=value which allows setting a portion
1164 of MARC header to a certain value.
1166 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1168 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1169 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1171 --- 2.1.26 2006/08/15
1173 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1176 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1178 --- 2.1.24 2006/08/08
1180 Fixed MARC ISO2709 encoding routines to deal with character set
1183 Minor changes to GFS logging. Database included in search request log
1186 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1187 cached/multiple records.
1189 Shared libraries are built by default on Unix+configure.
1191 Changed cql2pqf transformation to use a different evaluation order. The
1192 new order is: always, relation, structure, position, truncation, index
1193 and relationModifier. Old order was: always, relation, relationModifier,
1194 structure, index, position, truncation. Note that the the latter ones
1195 override former ones for identical attributes.. The new scheme means that
1196 it is possible to override any existing attribute with a relationModifier.
1197 And also that it is possible to override everything for the index rule
1198 (except the ones listed in relationModifier). No order is perfect but this
1199 one, we believe, covers more real cases.. The "always" should have been
1200 called "default", since the attributes there can be overridden with all
1203 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1204 compilation phase, but also for yaz-config --cflags output. This allows
1205 us to have public headers with Libxml2 stuff in them . It should also,
1206 eventually, make Libxml2 checks redundant in packages using YAZ, such
1209 --- 2.1.22 2006/06/15
1211 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1212 stored in uri, message and details.. Previously diagnostics were stored
1213 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1214 compatibility.. but he's probably the only one affected, so.
1216 Added support for CCL, compiled on the client side, in ZOOM-C. This
1217 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1218 input; the resulting query objects can be used for for searching with
1219 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1221 YAZ' configure searches for OpenSSL by default.
1223 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1224 SL_CTX_use_certificate_file. See
1225 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1226 for more info. Thanks to Ko van der Sloot.
1228 --- 2.1.20 2006/06/02
1230 Bug #600: SRU GET, POST support for yaz-client. Introduced
1231 command 'sru' which selects method SOAP/GET/POST.
1233 Allow missingValueAction to be specified for the sortspec string -
1234 function yaz_sort_spec. By default, the missing value action is null.
1235 Use ! to specify "abort". Use = followed by stringvalue to specify default
1238 Ensured that Present-handler (if defined) is called in GFS before any call to
1239 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1240 searchRetrieve requests.
1242 Documentation for YAZ is now based on the Docbook XML/XSLT using
1243 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1244 is no longer depending on jade/openjade or docbook-to-man scripts.
1245 PDF is no longer part of the distribution - but can optionally be
1246 made using DSSSL/jadetex or FOP.
1248 Added retrieval handling support in Generic Frontend Server to support
1249 conversion between MARC/XML as well as XSLTtransforms. See
1250 etc/yazgfs.xml for an example.
1252 Added Authentication support to Generic Frontend Server in SRU
1253 mode. Authentication using HTTP Basic is supported, as is the use
1254 of 'x-username' and 'x-password' parameters in the request itself.
1256 Added support for a new character set MARC8s identical to MARC8 except
1257 that it converts combined characters to single Unicode characters in the
1258 Latin-1 range (when possible).
1260 --- 2.1.18 2006/04/24
1262 ASN.1 compiler 0.4: generates brief Doxygen file header for
1263 generated .h/.c files.
1265 Utility yaz_iconv now supports conversion to MARC-8.
1267 New facilities for the MARC module. The reading - and writing of
1268 content are separate methods for the yaz_marc_t handle. The following
1269 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1270 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1271 format). Write functions have prefix yaz_marc_write_.. The existing
1272 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1273 available. Removed support for OAI-MARC and simplexml (not the
1274 simplexml from PHP5).
1276 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1277 to be returned for this connection.
1279 --- 2.1.16 2006/03/31
1281 Allow multiple languages and charsets to be specified with
1282 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1283 negcharset iso-8859-1,utf-8
1285 Translation of proximity nodes from CQL into PQF now works.
1287 Moved to automake 1.8, 1.9.
1289 Added function yaz_log_set_handler which allows a log handler to be
1290 installed. This handler will be called for all log messages. Output
1291 to file is also produced; but that can be disabled by passing NULL
1292 fname to yaz_log_init_file.
1294 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1296 For SRW (including GFS), accept application/soap+xml as content-type
1299 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1300 produces NO stylesheet reference even if a default stylesheet is specified
1303 --- 2.1.14 2006/03/14
1305 Updated Windows package to include yazd.dll + yazd.lib for the
1306 Development component.
1308 If the environment variable YAZ_LOG is set, then it is used as a
1309 string indicating the default level of logging to use if not
1310 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1311 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1312 used as before. So, for example, to omit warnings from YAZ logging,
1313 export YAZ_LOG=-warn
1315 cql_transform() now map structure and other attributes before indexes,
1316 so that index-specific structures and other attributes can override
1317 defaults. So now a combination of mapping specifications such as:
1319 index.dc.date = 1=date-modified 4=5
1320 does the right thing.
1322 cql_transform() now also respects the "always" mapping specification,
1323 which establishes an initial set of attributes to be used for all
1324 terms except where overridden by more specific attributes associated
1325 with the index, relation or modifier.
1327 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1328 which mode to use; one of "post", "get" or "soap" (SRW, default).
1330 Fixes for yaz_iconv routines: changed trie-based character set conversions
1331 to use only non-negative values for bit fields due to Sun's C compiler not
1332 supporting negative values.
1334 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1335 sequences where not read correctly. Fix by Rustam Usmanov.
1337 Updated win/makefile to use options, settings which makes things
1338 compile with VS C 2005.
1340 --- 2.1.12 2006/02/01
1342 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1344 In ZOOM socket code, use select instead of poll on MacOSX.
1346 ZOOM-C now support client-side compilation of CQL into RPN that is
1347 sent to the server, enabling CQL to be used against all Z39.50
1348 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1349 ZOOM_query object, and submit it using ZOOM_connection_search().
1350 The CQL-to-RPN translation uses a configuration file, the name of
1351 which must be specified in the Connection's "cqlfile" option.
1353 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1354 function, which takes as its start-term parameter a ZOOM_query object
1355 (which may have had either CQL or RPN set into it).
1358 --- 2.1.10 2005/11/29
1360 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1361 GFS to support this as well. Backend handler, bend_srw_update, does the
1362 update work. Code contributed by Ko van der Sloot.
1364 Allow retrieval of Search Result-1 information in ZOOM by the use of
1365 options that are attached to a result set. ZOOM documentation updated
1368 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1369 UTF-8 conversion. Patch by Raj Patel.
1371 Added option -m to GFS to control formatting of timestamps in log file.
1373 Added 'exit' as synonym for 'quit' in yaz-client
1375 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1376 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1377 for the new members. Patch by Ko van der Sloot.
1379 Added support for SRU POST. It is supported for content-type
1380 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1382 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1383 Instead make the library libyaz.la multi-threaded. Threading as a whole
1384 can still be disabled by configure option --disable-threads. Previosly,
1385 with older GLIBCs there were problems with MT libs under Apache. This
1386 has now been fixed a long time ago.
1388 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1391 CQL module modified to be case insensitive for relations/indexes/operations.
1393 Fixed bug in CQL transform code: incorrect value relationModifieder
1396 Added 'show all' command for yaz-client which retrieves all results
1399 Added new yaz-client, xmles, which takes a (private) OID and
1400 a document to be sent as an extended service request.
1402 Describe new yaz-client commands wait_response and set_auto_wait.
1404 Increase TCP/IP listener backlog from 3 (which I am guessing was
1405 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1406 that the socket will queue as many incoming connections as it's able
1407 to handle ongoing connections. In other words, it will never now
1408 refuse a connection that it would be able to handle merely because
1409 it's not got around to accepting() enough of the pending connections
1410 yet. This is the behaviour anyway under Linux, where the listen()
1411 argument is ignored; but not under BSD and on systems such as
1412 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1413 YAZ-based servers should now be uniform across operating systems in
1416 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1417 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1418 This allows yaz-marcdump to read large MARC batches (>2 GB).
1420 Modified all YAZ source files - except the source which is auto-generated
1421 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1424 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1425 corresponding to the existing *_setl() function. These allow option
1426 values containing arbitrary valuues.
1428 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1429 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1430 except that it returns an indicator of whether or not the sort
1431 criterion was accepted (0 for OK, -1 for invalid).
1433 --- 2.1.8 2005/06/07
1435 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1436 MARC output rather than returning "new" buffer.
1438 yaz-client warns about unknown init options.
1440 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1442 --- 2.1.6 2005/05/24
1444 Added support for SRW sort in Generic Frontend Server. Patch
1445 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1446 sortKeys - or NULL if none is provided.
1448 Fixed bug #307: It was impossible to specify indefinite/no timeout
1449 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1452 Added support for multiple languages and charsets to be specified in
1453 ZOOM. Each charset/language is separated by a blank. If negotiation is
1454 in effect in init-response, Option
1455 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1456 Code based on patch by Vasiliy Osadchuk.
1458 Fixed bug #306: infinite recursion that occurred when calling
1459 yaz_log_level_init as the first call (before other log level or
1462 Fixed bug in scan handling in front end server: if preferred-Position-In-
1463 Response was non-present, a NULL pointer referece was performed.
1465 --- 2.1.4 2005/04/26
1467 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1468 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1469 now defined for all those error codes. So instead of putting 109 in
1470 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1471 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1473 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1476 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1478 Program yaz-client now exits and produces an error message if multiple
1479 Z39.50 servers are specified on the command line (none or one allowed
1482 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1485 --- 2.1.2 2005/03/16
1487 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1489 Fixed bug #272: Preserve spacing for CCL terms.
1491 --- 2.1.0 2005/03/14
1493 Added support for virtual hosts and multiple backend servers for
1494 the YAZ frontend server. The configution is XML based and
1495 support specificition of CQL to RPN mappings and explain information.
1496 See section "Virtual Hosts" in the YAZ manual.
1498 Extended OPAC display utility. OPAC display utility renders
1499 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1500 to supplement yaz_marc_decode_wrbuf.
1502 Fixed a bug in MARC decoder that could caused it to crash for some
1503 invalid MARC records. More diagnostics and warnings where added in
1504 XML output (warnings, etc are stored in comments).
1506 --- 2.0.34 2005/02/08
1508 Fixes for UNIX domain sockets. Bug #261.
1510 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1512 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1513 Added yaz_marc_subfield_str which defines subfield lead string which is
1514 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1515 yaz_marc_endline_str which defines end of fields string used in
1516 YAZ_MARC_LINE format. Default string is newline.
1518 Experimental support for MarcXChange. This format can be produced
1519 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1520 http://www.bs.dk/standards/MarcXchange.xsd
1522 Added yaz-client commands scansize that sets maximum number of
1523 entries to be returned by scan.
1525 --- 2.0.32 2005/01/11
1527 Added support for SRW scan in yaz-client and Generic Frontend Server.
1529 * Added whereInList member to SRW Scan Term.
1531 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1533 Fixed NMEM system to return aligned blocks on the smallest boundaries
1534 that are suitably aligned for all possible types on the particular
1535 architecture YAZ is being built for.
1537 --- 2.0.30 2005/01/04
1539 Fixed numerious warnings that was issued with newer versions of GCC.
1541 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1542 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1545 Make YAZ Generic Frontend Server slightly faster.
1547 Enhance (and reduce) logging for Generic Frontend Server.
1549 Revert YAZ log system so that it flushes every write operation
1550 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1552 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1553 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1554 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1555 will effectively disable old definitions.
1557 --- 2.0.28 2004/11/09
1559 Added yaz_log_time_format which specifies log format using
1562 Added yaz_log_module_level which returns mask for a module. Value
1563 is non-zero mask a if module is enabled; zero if disabled.
1565 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1566 in include/yaz/cql.h.
1568 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1570 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1572 Fixed bug #172: RPM builds does not enable SSL.
1574 Doxyfile.in part of dist. Doxyfile generated by configure.
1576 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1577 are given and the corresponding component does not exist.
1579 Extend CCL documentation in YAZ reference. Describe r=r.
1581 --- 2.0.26 2004/10/01
1583 Fixed MARC->MARCXML conversion to properly deal with
1584 fields, subfields, indicators having non-ASCII characters.
1586 Fixed MARC->MARCXML conversion so that ASCII control characters
1587 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1590 Added YAZ GFS support for conversion from Z39.50 surrogate
1591 diagnostics to SRW surrogate diagnostics.
1593 Bug fix: YAZ GFS did not return schema in explainResponse.
1595 --- 2.0.25 2004/09/30
1597 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1598 now converts recordSchema to elementSetName as well as schema URI.
1600 Fixed bug in COMSTACK that prevented HTTP request packages from being
1603 --- 2.0.24 2004/09/29
1605 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1606 does not require white-space before and after the dash in a range, e.g.
1607 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1610 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1611 due to new GCC removing "redundant" code.
1613 Added yaz-client commands scanpos and scanstep that sets preferred
1614 position and step-size for scan.
1616 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1618 Added CCL utility ccl_qual_buf which parses one or more CCL
1619 spec lines in a buffer.
1621 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1622 of name and value - ignoring empty lines and comments.
1624 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1626 Added odr_get_element_path which returns current element path for an
1627 ODR handle. This utility is useful in error handling or user-defined
1630 Added ODR_PRINT utility odr_set_stream which is is a more generic
1631 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1632 to a write function and pointer to close function. The close function - if
1633 non-NULL - will be called during odr_destroy.
1635 Fixed bug in CCL parser where truncation char was not removed from
1636 right side when truncation=both was in effect.
1638 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1641 --- 2.0.23 2004/08/11
1643 Fix buffer overrun in CQL parser when dealing with proximity (%).
1645 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1646 to UTF-8/UCS conversion is now only based on codetables.xml.
1648 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1650 --- 2.0.22 2004/08/06
1652 Add support for more "commit changes" in ZOOM (uses Extended Services).
1654 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1657 Yet another small fix for configure of SSL.
1659 --- 2.0.21 2004/05/14
1661 Fix SSL libs for configure when --with-openssl=DIR is given.
1663 --- 2.0.20 2004/05/10
1665 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1667 SSL comstack now uses yaz.pem certificate file on server side
1668 by default. Certificate filename can be configured by calling
1669 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1671 Fix bug regarding multiple calls to ZOOM_connection_connect.
1673 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1675 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1676 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1678 ZOOM now allows inspection of X509 peer certificate for verification.
1679 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1681 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1682 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1683 as "modular" but it simplifies things.
1685 Added cs_get_peer_certificate to that returns peer X509 PEM.
1687 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1688 NULL if SSL is unavailable.
1690 Documentation about MARC decoding tools.
1692 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1694 --- 2.0.19 2004/03/30
1696 Rename CHANGELOG to NEWS to follow GNU style packing.
1698 Fix bug with missing initialization of member in init_diagnostics.
1699 This bug affects threaded version of GFS server.
1701 --- 2.0.18 2004/03/20
1703 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1706 Ensure zlib.dll is packed with Windows install.
1708 --- 2.0.17 2004/03/17
1710 Fix encoding of xsd:string to use text instead of CDATA.
1712 Fix endless loop in CQL parser with unbalanced ".
1714 Use a more compact way to store MARC-8 conversion tables.
1716 --- 2.0.16 2004/03/16 Debian only
1718 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1721 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1726 --- 2.0.15 2004/03/01
1728 Another fix for decoding of XML packed records.
1730 --- 2.0.14 2004/02/25
1732 Fixes for Chunked encoding. White space not ignored after length spec.
1734 Update NS and use default NS for SRW diagnostic elements.
1736 --- 2.0.13 2004/02/23
1738 Implement ZOOM_resultset_cache_reset which resets record cache.
1740 Implement ZOOM_resultset_sort which sorts a result set.
1742 Implement chunked HTTP transfer.
1744 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1746 --- 2.0.12 2004/02/16
1748 Added member 'schema' to bend_explain_rr structure so that backend
1749 can specify explain record identifier. Defaults to Zeerex 2.0.
1751 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1753 --- 2.0.11 2004/02/16
1755 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1758 Added init command for yaz-client which sends "extra" init request.
1760 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1761 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1763 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1765 Make ZOOM error code for "invalid query".
1767 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1769 --- 2.0.10 2004/02/05
1771 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1774 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1776 Added option -p <file> to make Generic Frontend Server to write PID file.
1778 Added option -D to put Generic Frontend Server in background on its own.
1780 Make ZOOM C recognize option "password". If unset, "pass" is used
1781 (for backwards compatibility).
1783 Fixed a bug in Generic Frontend Server that could make it crash if a
1784 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1787 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1788 Must be issued before open, in order to be in effect.
1790 --- 2.0.9-6 2004/01/12 Debian/Windows
1792 Make the SRU server more picky WRT unknown params, etc.
1794 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1796 New YAZ client command, options, that sets Z39.50 options.
1798 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1799 options from a string of tokens (one token for each option bit).
1801 Update SRW diagnostic code messages.
1803 --- 2.0.9-5 2004/01/07 Debian/Windows
1805 Handle user defined stylesheet for SRW/SRU.
1807 --- 2.0.9-4 2004/01/06 Debian/Windows
1809 Fix bug in decoding of Content-Length.
1811 --- 2.0.9-3 2004/01/06 Debian/Windows
1813 Fix a bug with decoding of XML packed records.
1815 --- 2.0.9-2 2004/01/05 Debian only
1817 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1819 Fix bug in SRW/SRU diagnostics decoding.
1821 --- 2.0.9 2004/01/05
1823 Fixed bug in Generic Frontend Server which could drop records exceeding
1824 preferred message size. Reported and fixed by Irina Dijour.
1826 Fixed calculation of package size for structured records in Generic
1827 Frontend Server. Reported and fixed by Irina Dijour.
1829 Fixed namespace for SRW/SRU diagnostics.
1831 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1833 --- 2.0.8 2003/12/22
1835 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1836 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1839 CQL changes to reflect recent changes to the specification:
1840 * Documentation talks about context sets instead of index sets.
1841 * Documentation talks about indexes instead of qualifiers.
1842 * The CQL-to-PQF transformer's configuration file now uses
1843 "index.set.name = <attributes>" instead of the old form
1844 "qualifier.set.name = <attributes>". (Both forms are still
1845 understood but the latter is deprecated.)
1846 * CQL terms with no explicit index specified are now interpreted as
1847 cql.serverChoice instead of srw.serverChoice (which of course
1848 behaves exactly the same.)
1850 --- 2.0.7 2003/12/16
1852 MARC conversion can now generate ISO2709 output in another
1853 character set. yaz-marcdump uses this facility if you invoke it
1856 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1857 functions from there can be used from C++.
1859 --- 2.0.6 2003/12/04
1861 Frontend server now transfers memory from decoded packages to stream
1864 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1865 references to show up.
1867 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1868 the ZOOM Abstract API. The older names for the same options are still
1869 also supported for the benefit of old applications.
1871 ZOOM-C supports "implementationId" and "implementationVersion" options
1872 to go along with "implementationName". These allow the user code to
1873 specify identification strings to be sent to servers.
1874 Add OID for the new ExtLite attribute set.
1876 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1877 as requested/supplid by Ere Maijala <ere@atp.fi>
1879 For generic frontend server, reverse the order of
1880 "toolkit-supplied / application-supplied" strings sent as implementationId,
1881 Name and Version. Also, remove the spaces around the slash. This brings
1882 the GFS in line with the behaviour of ZOOM-C on the client side.
1884 Add function ZOOM_scanset_display_term.
1886 yaz-client shows scan displayTerm if present.
1888 Utility yaz-iconv is now installed by default along with the man page
1891 Extend configure check for OpenSSL to use pkg-config where available (such
1894 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1895 server to specify uid/gid/mask for socket using the format
1896 unix:[user=uid,][group=gid,][umask=mask,]file=path
1897 If file= is omitted the existing format is assumed, e.g.
1899 in which case the mask is 0666 (rw for everybody).
1901 Major restructure of YAZ source. All source in libyaz is in src directory.
1902 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1903 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1905 Added man page for utility yaz-marcdump (used to be called marcdump).
1906 yaz-marcdump is installed by 'make install'.
1908 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1909 of incoming package failed.
1911 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1913 Change prototype of odr_perror: add const to message string.
1915 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1917 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1918 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1919 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1920 DNS lookup. There should not be any compatibility problems with this
1921 assuming that blocking=1 or 0 is used.
1923 Fix bad reference in UNIX comstack in function cs_addrstr.
1925 Fix for compilation on AIX.
1927 The generic front-end server (server/seshigh.c) now supports returning
1928 Init diagnostics to the client in User-information-field, in
1929 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1932 --- 2.0.4 2003/09/04
1934 Allow any CQL relation (not just all,any,exact,scr).
1936 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1937 that features the same UI.
1939 Implemented command update0 in YAZ client which is equivalent to
1940 update but uses old of Ext Update ASN.1.
1942 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1943 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1944 Previously no OID was used for this info.
1946 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1947 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1948 returns 'malformed search term' otherwise.
1950 SortResponse member resultCount now set to NULL in sort handler of
1953 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1956 Add three new utility functions for translating OIDs between various
1957 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1958 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1959 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1960 char *oid_to_dotstring(const int *oid, char *oidbuf);
1961 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1963 Reverted modifications for ES Update definition for z_IU0Update
1964 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1965 is back to YAZ 2.0.2.
1967 String value attributes for CCL parser.
1969 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1970 which their FirstSearch server returns in Init responses, sometimes
1971 carrying useful diagnostic information when Init fails. This has the
1972 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1973 "z39.50/oclcui.asn", where its definition is somewhat different from
1974 what OCLC document on their web-site, as required to interoperate with
1977 Support for anonymous authentication in yaz-client. Use the command
1980 * Fix the OID of the Index Data-local "admin" Extended Service from
1981 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1982 the 1000, which indicates a locally-defined OID, was a mistake.
1984 --- 2.0.3 2003/06/20
1986 Fix CCL directive @case handling so that it affects string match for
1987 both CCL keywords and qualifiers.
1989 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1990 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1991 Decoder has been updated with ASN.1 changes as listed in
1992 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1993 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1994 z_IUUpdate, remains unchanged.
1996 ZOOM_record_get may now return a record in a specific character set.
1997 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1998 "from" is the character set of record as returned by target. "to" is
1999 the character set to be returned. If omitted, "to" is UTF-8.
2001 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2003 New ODR utility, odr_getelement, which returns name of element for
2004 which encoding/decoding failed.
2006 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2007 in cases where a required element was omitted.
2009 Bug fix: some MARC8 sequences were not converted.
2011 New ZOOM option "step" which specifies number of records to be
2012 retrieved in one chunk. Used in conjunction with "start" and "count".
2014 SRW support for yaz-client. Use scheme http: to use it, e.g.
2017 yaz-client no longer does (un)intelligent character set conversions
2018 by default. Can be enabled with charset and marc_charset commands.
2020 xmalloc trace fix for 64-bit systems such as DEC alpha.
2022 Solaris 2.6 compile fix.
2024 New function, cql_strerror() translates SRW error codes, as returned
2025 by cql_transform_error(), into human-readable English strings. Used
2026 in yaz-client diagnostics when appropriate.
2028 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2029 converts it into a type-1 query which is sent to the server. This
2030 makes CQL available for use with all Z-servers, as opposed to the tiny
2031 minority that can handle CQL queries themselves.
2033 --- 2.0.2 2003/04/28
2035 New Debian package layout similar to the Redhat Package layout.
2037 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2038 and search result respectively.
2040 --- 2.0.1 2003/04/25
2042 Redhat package is now several packages: libyaz (runtime libraries),
2043 libyaz-devel (development and documentation, and yaz (utility programs).
2044 Package spec file by Morten Bogeskov.
2046 New member 'schema' in struct bend_fetch_rr which the name of requested
2047 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2048 handler MAY set this to reflect the schema of the returned record.
2050 New member 'display_term' in struct scan_entry. GFS now sets member entries
2051 and allocates scan entries to be filled by user scan handler. In previous
2052 version, entries member was allocated by the scan handler. That still works,
2053 but the GFS will ignore member display_term - assuming it was NOT set by
2054 the handler. The fact that the GFS now allocates the entries both allows
2055 for new members and makes a scan handler easier to write.
2057 Fix CQL lex buffer overflow.
2059 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2060 SRU default recordPacking is string.
2062 SRU protocol support for frontend server.
2064 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2066 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2068 Added scan for the ZOOM shell (zoomsh).
2072 * String Identifers for Schemas (Amendment 5).
2073 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2074 Old definition for schema
2075 Odr_oid *schema; /* OPT */
2080 Z_InternationalString *uri;
2081 #define Z_Schema_oid 1
2082 #define Z_Schema_uri 2
2085 * resultCount parameter to Sort Response (Amendment 1).
2086 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2088 Support for SRW 1.0 over HTTP. This is an optional feature and
2089 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2092 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2093 on the same port. SRW SearchRetrieveRequests are mapped
2094 to bend_init,bend_search,bend_fetch,bend_close.
2096 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2098 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2099 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2101 ZOOM connections are SRW based if schem http is used for hostname
2102 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2103 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2105 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2106 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2107 distance=n, order=true/false, relation=le, prox unit=word. If
2108 n is omitted, distance 1 is used.
2110 Fixed problem with C compiler include path in wrong order.
2112 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2113 on Solaris. Patch from Ko van der Sloot.
2115 New MARC decode API. All new functions operate on a yaz_marc_t
2116 handle. The most important new functions are: yaz_marc_create,
2117 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2118 decode and destroy respectively. Decoder can produce formats
2119 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2120 include/yaz/marcdisp.h.
2122 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2123 to UTF-8, UCS-32, wchar_t or Latin-1.
2125 * Prototypes for yaz_iconv_-functions moved to separate header
2126 include/yaz/yaz-iconv.h.
2128 Make a few private functions 'static' in unix.c. This prevents
2129 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2131 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2132 are set when Init Response is received.
2134 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2135 but returns diagnostic set as well.
2137 New function yaz_strerror which is a portable wrapper for
2138 strerror/strerror_r/GetLastMessage.
2140 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2141 is returned for MARC. If type is "oai", then OAI MARC is returned.
2143 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2146 --- 1.9.2 2002/11/26
2148 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2150 Fix bad race conditions on SIGTERM and terminate gracefully in
2153 Move retrieval (data1) module to Zebra since nobody seems to be
2156 Add GRS-1 render for ZOOM using same format as yaz-client.
2158 --- 1.9.1 2002/10/05
2160 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2162 Fix broken ESpec handling in data1 module.
2164 SGML reader parses comments and makes them part of the data1 tree.
2166 Added several type casts so that YAZ compiles as C++ code.
2168 ZOOM didn't handle PDU encoding failures properly.
2170 Added more Bib-1 diagnostics (approved extensions).
2172 GNU configure: better check for iconv.
2174 More portable use of accept, getpeername. Check for socklen_t. Use
2175 int/size_t if socklen_t is not defined.
2179 PQF parser rejects bad queries - including those with extra
2180 characters in them. PQF parser used to silently ignore that.
2181 Cleaner API for PQF added, which allows you to get detailed
2182 error information for bad queries (see yaz/pquery.h).
2184 Fixed bug in ZOOM_record_get for type "database".
2186 Implemented mini iconv library supporting conversions between
2187 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2189 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2191 --- 1.8.9 2002/08/20
2193 Fixed ZOOM C record cache so that preferredRecordSyntax and
2194 elementSetName is used to check for already fetched records.
2196 --- 1.8.8 2002/08/02
2198 Added three members in bend_initrequest structure to facilitate
2199 character set negotiation.
2201 Fixed a bug in frontend server that could cause indefinite
2202 loops under rare conditions.
2204 Revised character set utilities (charneg.h) so that encoding
2205 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2207 For PQF, directive @term <type> sets term type for Scan/Search.
2208 Here <type> is general, string, numeric, null. The term type
2209 is inherited - just like @attr.
2211 New call odr_set_charset that sets character set conversion for
2212 international-strings on a ODR stream. Prototype is:
2213 int odr_set_charset(ODR o, const char *to, const char *from);
2214 The InternationalString is still represented as C string in YAZ
2215 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2216 won't). On the protocol level, you can use any encoding.
2218 Support for UNIX sockets in ZOOM.
2220 Solaris recv sometimes returns errno == ENOENT. It is treated as
2221 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2223 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2224 both client and server. Code by Morten Bogeskov.
2226 --- 1.8.7 2002/05/22
2228 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2229 that they can be used directly from Visual Basic. You must recompile
2230 your windows APP if you're using ZOOM.
2232 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2233 Commands "lang" and "charset" sets language and character set respectively.
2234 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2235 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2237 Attributes from multiple CCL fields may be OR'ed rather than merged
2238 using directive "@field or". Fields are still merged by default -
2239 equivalent to "@field merge".
2241 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2244 Fixed bug in zget for parameter ExtendedServicesResponse.
2248 --- 1.8.6 2002/03/25
2250 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2252 Client displays USR.1:SearchResult-1 (hits per term).
2254 Additional Search Info for search in Generic Frontend Server.
2256 Fixed CCL parsing of "field=s".
2258 WIN32 installer - using the excellent NSIS software from nullsoft.
2260 Fixed CCL parsing of "field = - <number>".
2262 Added function yaz_marc_decode that decodes MARC for line mode
2263 display or XML (similar to that used by JZKit).
2265 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2266 Z39.50. But ISO/ILL was, however.
2268 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2269 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2271 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2272 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2274 --- 1.8.5 2002/02/03
2276 New YAZ client features: Command completion and new commands:
2277 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2278 Code provided by Jacob Poulsen.
2280 New call oid_trav, that visits all registered OIDs via callback.
2282 Function ZOOM_record_get now returns const char pointer rather than
2283 void pointer. It saves a lot of type casts.
2285 For YAZ client, command "auth" now allows you to set authentication
2286 in IdPass style. It is enabled when three tokens are given - order
2287 is user, group and password.
2289 Fix memory leaks in MARC record handling for ZOOM.
2291 New option for YAZ client, -k <kilobytes> that sets
2292 maximum record size. Similar to -k option for generic frontend
2293 server and yaz-ztest.
2295 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2297 Prefix query parser reports "fail" when bad attribute set is given.
2299 Fix in MARC decoder. Proximity logging. Fix for attribute set
2300 in scan handler for server. Patches by Shigeru Ishida.
2302 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2305 Configure option --with-openssl=<dir> now works when a directory is
2306 specified. Patch provided by Morten Bogeskov.
2308 New option for YAZ client, -u <auth>, that sets authentication.
2310 ZOOM fix: error information was sometimes "missing", since error
2311 was cleared/reset too when it shouldn't.
2313 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2315 --- 1.8.4 2002/01/04
2317 Scan for ZOOM API. New object ZOOM_scanset. New functions
2318 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2319 ZOOM_scanset_destroy.
2321 New ZOOM function, ZOOM_connection_last_event, that returns type
2322 of last event (such as "receive data", "send data", "apdu received",
2325 New ZOOM option, schema, that specifies schema for retrieval.
2327 New CCL feature. Qualifiers can be aliases for one or more
2328 other qualifiers (if more than one is given, OR is used).
2330 ZOOM uses named result sets if target supports it.
2332 Two new YAZ client commands: . (dot, which sources a script of YAZ
2333 client commands), and ! (to execute shell command.). Implemented
2336 Working on Debian packages.
2338 --- 1.8.3 2001/11/19
2340 YAZ client enables named result sets only if target supports it.
2342 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2344 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2345 with key="host" to get same result.
2347 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2348 Function Z3950_resultset_record(s) returns references to records
2349 "owned" by resultset. To become owner use Z3950_record_clone.
2351 Function z_ext_record handles Extended Services. Thanks to
2354 --- 1.8.2 2001/11/12
2356 CCL Parser fix: ignore token comma when dealing with and-lists.
2358 Documentation updates for COMSTACK.
2360 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2361 Changed prototype Z3950_records. For some functions, int parameters
2362 were changed to size_t.
2364 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2367 New MARC decode/display function, marc_display_exl, which properly rejects
2368 non-ISO2709 records. YAZ client uses it.
2370 --- 1.8.1 2001/10/29
2372 Fix bug: local attribute set wasn't set correctly in PQF strings.
2376 * Old Z39.50 codecs no longer supported.
2378 Added ZOOM C binding. See http://zoom.z3950.org/
2380 Renamed states for COMSTACKs to avoid confusion with events.
2382 Implemented cs_look and proper cs_rcvconnect.
2384 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2386 Configure detects POSIX threads on OpenBSD.
2388 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2389 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2391 When error is returned from present handler, non-surrogate diagnostic
2392 is returned in present response (and fetch handler is no longer called).
2394 * Minor adjustments to pquery parser (PQF). Token characters may be
2395 escaped by using backslash (C-style).
2397 PQF parser allows string attribute values to be specified. For @attr,
2398 non-numeric characters after the equal-sign are treated as strings
2399 (e.g. @attr 9=title).
2401 CCL trunction character may be defined (@truncation in file)
2403 * function zget_ExtendedServicesRequest sets waitAction to
2404 waitIfPossible (was wait).
2406 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2409 CCL operator names may be set in field definition files (CCL_bibset).
2410 See ccl/bib1 for an example.
2412 Fixes in ASN.1 compiler for C++ compatibility.
2414 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2415 and "op_or" to avoid conflict with C++.
2417 Fixed problem with GNU readline detection on Redhat 7.0.
2419 Added step-size for Scan backend handler.
2421 Fixed bug that made the frontend server crash when no attribute
2422 set was specified for scan.
2424 Front-end server automatically switches to original working directory
2425 when installed as an NT service. Previously -w had to be specified to
2428 Added extended attributes for retrieval module (data1), so that data1
2429 records carry d1_readXML/SGML attributes. d1_read also supports
2430 null-data rules ( <tag/>)
2432 On UNIX when POSIX threads are available, a separate library libyazthread
2433 is created. Programmers should link with that library and the yaz library
2434 when using threads. The reason for the split was that some applications
2435 on Linux, such as Apache, doesn't work well when using shared objects that
2438 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2439 (or any frontend server) in SSL mode by specifying ssl: followed by
2440 address. Only tested on UNIX.
2442 Added feature for CCL module. Virtual structure s=al or s=ol generates
2443 and-list and or-list respectively instead of phrase search.
2447 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2448 log_mask_str. This was done to avoid name conflicts with other libraries
2449 (such as other PHP extensions).
2451 Added raw OID member for preferred record syntax (request_format_raw)
2452 and returned record syntax (output_format_raw) for backend fetch method.
2454 Config file yaz-config now accepts options so that it returns specific
2455 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2457 Shared library support for UNIX using GNU libtool.
2459 * Modified backend interface. Request/Response struct's replaced by
2460 one read/write C struct. For example bend_fetchrequest and
2461 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2462 Every handler - even search has to be registered in bend_init
2463 handler. This means that the YAZ library no longer refers to
2464 external functions and it makes it possible to make the whole
2465 thing a single DLL/SO.
2467 Added Segment handler for backend server.
2469 Added Zmbol/Zebra administrative functions to YAZ client.
2471 Threaded frontend server on UNIX (when POSIX Threads are available).
2472 Starting the server with option -T enables multi-threading.
2476 Added configure option --enable-comp/disable-comp to control use
2477 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2478 located in sub directory asn.
2480 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2481 in ${exec_prefix}/bin along with the other programs yaz-client and
2484 GNU automake used to maintain makefiles.
2486 Added several OID's.
2488 Changed retrieval module so that we can load records with no abstract
2489 syntax defined. Tagpaths in these records are fully composed of string
2492 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2496 On UNIX, the generated makefile now supports a proper 'make install'.
2497 The prefix can be set via GNU configure to set the install location
2498 (default is /usr/local).
2500 * YAZ programs client and ztest were renamed to yaz-client and
2501 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2502 locations, such as /usr/bin,/usr/local/bin,etc.
2504 * YAZ Header files were moved from include to include/yaz. YAZ Header
2505 files are referred to as include <yaz/log.h> rather than <log.h>.
2506 The YAZ include path (-I ..) is therefore the same as before. Programmers
2507 should update their #include statements or use -Ipath/include/yaz
2508 instead. The main motivation for doing this change is that YAZ header files
2509 can be installed in "standard" locations /usr/include,/usr/local/include
2510 without introducing conflicts, since ALL YAZ header files are stored
2511 in subdirectory yaz (under /usr/include for example).
2513 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2514 rather than project/workspace files. We switched because project files
2515 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2518 Changed name of logging function, logf, to yaz_log, to prevent name
2519 clash with some math-log functions. The YAZ header log.h defines logf
2520 to yaz_log (#define) so there should be no incompatibilities by this
2523 Added bend_start/bend_stop handlers for server. These handler are
2524 called on start/stop of server. For windows they are called whenever
2525 a service is started/stopped.
2527 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2528 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2529 in util/yc.tcl. The auto-generated C code structures are, in a few
2530 cases, incompatible with the old decoders. There are differences in the
2531 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2532 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2533 The preprocessor variable ASN_COMPILED is defined when the compiled
2534 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2535 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2536 wish to use the old encoders/decoders you can specify --disable-yc
2539 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2540 version so that it supports both new - and old version of DB Update
2542 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2543 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2544 change. The name parameter can be set to 0 in which no name is specified
2545 for the construction. The macros odr_implicit and odr_explicit sets name
2546 parameter to zero for the construction involved. New macros
2547 odr_implicit_tag and odr_explicit_tag are similar to the others,
2548 except that a name parameter is added. For programmers' that don't use
2549 ODR they probably only need to change the call to z_APDU and z_External.
2551 Added access control facility by interfacing the TCP wrapper library.
2552 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2553 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2554 name of the daemon and enables the access control as specified in
2555 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2557 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2558 den Dool <H.M.vdnDool@kub.nl>.
2560 Added reference ID parameter to most functions in server API - refer
2561 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2563 Changed name of ccl library to libccl.a (was ccl.a).
2565 Fixed bug in decoder for Explain (Category TargetInfo).
2567 Added support for GNU readline in client. Thanks to Jacob Poulsen
2568 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2570 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2571 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2572 IMPLEMENTATION! This change was made to the development version before
2573 the ZIG decided to retract the amendment. If any users MUST be
2574 compatible with the original Update definition, PLEASE CONTACT US, and
2575 we will include a separate definition corresponding to the old Update
2576 ES. Note that because of the change to the ASN.1 of the
2577 TaskPackageRecordStructure we cannot define a single structure that
2578 will support both versions.
2580 * Added const modifier to buffer parameter for some ODR/BER encoding
2581 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2582 completeWAIS, odr_dumpBER.
2584 Fixed bug in client.c which caused a crash when a scanResponse didn't
2585 contain positionOfTerm.
2587 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2588 * will cause an error in a client if a non-YAZ target sends both a
2589 * list of Scan entries and non-surrogate diagnostics.
2591 Retrieval module enhancements. Tag sets may be typed in the reference
2592 to it. From the .abs-file the "tagset" directive takes a third optional
2593 integer type for the tag set referenced. From a .tag-file the "include"
2594 directive takes a third optional type as well. The old "type" directive
2595 in the tag set itself is still recognized but acts as the default type
2598 Backend interface change. Individual Scan terms returned from bend_scan
2599 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2600 in include/backend.h.
2602 Retrieval module enhancements. Multiple tag sets and attribute sets may
2603 be specified in abstract syntax specs. Revised the error/warning for
2604 logging messages reported by the retrieval module when reading the
2607 Object Identifier system (oid_..) changed. The API is backwards
2608 compatible but the oid-routines now allocates new OID's when needed.
2609 Raw OID's may be specified in oid_getvalbyname.
2611 YAZ now uses GNU configure to generate Makefile(s).
2613 * Minor changes in some of the member names of DeleteResultSetRequest and
2614 DeleteResultSetResponse. See include/proto.h.
2616 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2617 and added member 'languages' in TargetInfo (which was missing).
2619 Changed the way attribute sets are handled in the retrieval
2620 module. These are now cached, just like the abstract syntaxes
2623 Changed YAZ so that it links with compiled ASN.1.
2625 Added Explain-schema definitions and mapping routines. The following
2626 Explain categories have been implemented: AttributeDetails,
2627 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2629 Fixed minor bug in Windows version of Server Library.
2631 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2633 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2635 Added EXTERNAL: UNIverse Resource Report (non-standard).
2637 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2638 ENUMERATED and SET OF.
2640 * Added 'const' to some of the char pointer arguments for the
2641 functions, data1_read_node, data1_getelementbytagname,
2642 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2645 Fixed bug in data1_insert_taggeddata - the last_child member of
2646 parent wasn't initialised.
2648 * Changed data1_read_record and data1_read_node so that the supplied
2649 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2650 doesn't refer to any parts of the "SGML"-buffer.
2652 Fixed bug in server library (Windows version of statserv_remove).
2654 * Changed code so that it compiles as C++. The type definition
2655 of Odr_fun which is a member of Odr_arm was changed. The result is,
2656 that an explicit typecast is needed for the fun pointer when
2657 using Odr_arm - as in:
2658 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2660 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2662 Implemented the new structured date and time definition as approved
2663 by the ZIG. Added schemaId element to the specificTag in Espec-1
2664 (also approved at the last ZIG). Thanks to RVDM.
2666 Added some Object identifiers (RVDM).
2668 Changed the Update Extended Service (RVDM).
2670 Added command "refid" to client which specifies referenceId for
2671 the following requests.
2673 Implemented extended service handling for server. See ztest.c
2674 for an example as well as backend.h. New handlers are registerd
2675 in the Init handler.
2677 * Changed interface for sort in server.
2679 Added new members to statserv_options_block. It allows a server
2680 to read options from another source than just the command line. Thanks
2681 to Charles Woodfield.
2683 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2684 renamed to zboolean. Some C++ compilers complained about the name.
2686 Minor changes to gils.abs. Added index 's' (sort) on title
2687 and date/time-last-modified.
2689 --- 1.4pl2 1998/1/30
2691 Fixed bug in server library regarding inetd mode (-i). This bug
2692 was introduced by release 1.4.
2694 --- 1.4pl1 1998/1/29
2696 Added sort facility in client and backend server interface.
2698 Fixed problem with dependencies in Makefile(s).
2700 Fixed bugs for encoders/decoders of extended services and
2703 Implemented sub-tree feature for schemas. Sub-trees are
2704 referenced in *.abs-files. See explain.abs for an example
2705 of the use of this feature.
2707 Modified bib1.att; local attributes for ANY didn't include
2708 ANY itself (only affects use of the retrieval module).
2710 Fixed bug in plain SGML reader in function data1_read_node:
2711 tags with prefix "var" was incorrectly interpreted as variants.
2713 Added feature "sub-schemas" to enable references to - and definitions
2714 of - group of elements.
2716 * Removed member parent from type data1_element (in data1.h).
2718 Implemented function odr_nullval() that returns the value of
2721 * Removed member num_children from data1_node (in data1.h).
2723 Made NT service interface part of the server library. The
2724 function statserv_main uses the NT service when required and
2725 calls the statserv_start / statserv_close routines.
2727 Routine zget_SearchRequest and zget_PresentRequest fills
2728 resultSetName/Id member with "default" instead of "Default".
2730 Fixed memory leak in server. Request queue member wasn't freed.
2732 Fixed nmem_exit so that memory is freed.
2736 Revised the CCL parser utility to be thread safe.
2738 Added function, oid_ent_to_oid, to replace the function
2739 oid_getoidbyent, which is not thread safe.
2741 * Added nmem_init and nmem_exit to initialize and release
2742 NMEM resources. Function nmem_init should be called once in the
2743 initial thread before NMEM/ODR is used. statserv.c and client.c
2744 have been changed accordingly. The change was necessary to make
2745 NMEM thread safe. The NMEM memory pool is shared amongst threads
2746 in a process. Unix-based applications will still work fine without
2749 Added NT Services interface for the the Z39.50 (statserv) Server.
2750 Refer to the ztest.c source on the usage.
2752 Windows 95/NT port using MSVC5.0. Project files are included in the
2755 * Defined new 'global' handle for the retrieval (data1) system. The
2756 new handled, data1_handle, describes the state of the data1 system.
2757 This handle is passed as first argument to virtually all
2758 data1 related routines. The functions data1_create and data1_destroy
2759 creates and destroys a data1 handle respectively.
2761 Added ODR encode stream member to all backend request structures
2762 init, search, scan etc. This stream should be used to allocate all
2763 memory used for the response when thread safe operation is needed.
2765 Changed the comstack utility, cs_addstr, to be thread safe. The
2766 returned hostname string returned by the function is now part the
2769 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2770 function. The cs_straddr takes a COMSTACK handle as argument, so this
2771 function must be used after cs_create and before bind/connect.
2772 This function is thread safe.
2774 Moved test server to 'ztest' directory - generic server code still
2775 in 'server' directory.
2777 Made prefix query (pquery.c) utility thread safe.
2779 Added new function modifier YAZ_EXPORT to 'export' public DLL
2780 functions when using windows (see include/yconfig.h).
2782 Added definitions to the OID database (util/oid.c) (RVDM).
2784 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2786 Added call to ccl_rpn_delete in client program.
2788 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2789 release of RPN structure.
2791 Added support for C++, headers uses extern "C" for public definitions.
2792 With input from RVDM.
2794 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2795 Thanks to Ronald van der Meer (RVDM).
2797 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2799 Added support for private extensions to the OID database
2800 (oid_setprivateoids()). Thanks to RVDM.
2802 Added optional, physical ANY (key replication)
2804 Fixed null-reference problem in GRS-1 output filter.
2806 Proximity operator added to Prefix Query Format (PQF).
2808 In test client command "base" accepts multiple databases.
2810 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2814 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2816 Smallish bug-fixes in the new encoders/decoders (explain).
2818 Bug fixed in DeleteRequest.
2820 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2822 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2824 Added SOIF syntax (using private OID for now) to retrieval module and client.
2826 Added Update extended service.
2828 Added SearchResult-1 additional info structure.
2830 Added optional CCL (ISO8777) interpreter as separate module. Available
2833 --- 1.2 1996/6/10 (1st anniversary release)
2835 Added Summary record syntax. Lightly tested.
2837 Added OPAC record syntax. Untested.
2839 Added ResourceReport service encoders/decoders. Untested.
2841 Fixed bug in z_Unit - wrong tagging on unitSystem.
2843 Fixed bug in the DiagRecs decoder.
2845 Added options for max PDU size and session timeout to frontend-server.
2847 Added documentation of query-language parsers and other supporting utilities.
2849 [frontend-server] Added Attribute set to the bend_scanrequest API.
2851 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2852 surrogate diagnostics were generated.
2854 [retrieval] Allow multiple local values for attribute.
2856 [retrieval] Allow multiple attributes per element in .abs files. index type.
2858 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2860 --- 1.1pl2 1996/4/10
2862 Minor changes, mostly specific to Zebra's requirements (retrieval)
2866 Repaired bug in frontend server when running multiple listening
2867 endpoints in dynamic mode.
2869 z_External() now won't break if a known, ASN.1 value comes encapsulated
2870 in an octet-string. The value will pass through unmodified in an Odr_oct.
2872 Added a bit of code to the demo client to decode & display
2873 ASN.1-structured records represented in the octet-aligned branch of
2874 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2876 Added z_ext_getentbyref() to the ASN module. Doc updated.
2878 * Completed the SCAN definition in the ASN module. This may break SCAN
2879 code based on older YAZ-versions at compile-time. The fix is easy -
2882 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2883 under the SCAN definition. Remember to initialize this, server-people.
2885 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2886 that this does not extend to ODR and ASN.
2888 Comstack allows insertion of established socket (primarily for
2889 inetd-operation of servers). Doc updated.
2891 Front-end server can now start from the inetd in TCP mode. Doc
2894 --- 1.0pl4 1996/1/24
2898 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2899 the rank and record number.
2901 Adjustments to the frontend server.
2903 Fixed diagnostic BER dumper. It ignored the file argument.
2907 Various changes to retrieval module.
2909 Changed the union discriminators of the protocol files from enums to
2910 ints paired with #defines.
2912 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2915 *Changed operator in the RPN structure to 'roperator', again to avoid a
2918 Fixed problems in Explain decoders/encoders.
2920 --- 1.0pl2 1995/12/6
2922 Memory bug in log module fixed.
2924 --- 1.0pl1 1995/12/5
2926 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2928 Bug in Explain DatabaseInfo module fixed.
2930 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2934 The shift to v1.0 signals that we now consider the *core* functionality
2935 of YAZ reasonably stable (the core being more or less equivalent to
2936 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2937 tested (Explain not at all - though that will happen soonish).
2939 Minor changes to code to support Windows port.
2941 Various minor changes after we're getting to use GRS-1 & co. more.
2943 Added Espec-1 format.
2945 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2946 of the protocol and it cannot be selected when encoding (maps into 'string'
2947 when decoding). Needed to talk to some servers.
2949 Demo client can request simple element set names.
2951 Added Diagnostic Format encoders/decoders.
2953 Added simple Close handling to frontend server (no hooks for resource
2954 reporting yet), and demonstration client.
2956 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2958 --- 1.0b3 1995/08/24
2960 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2961 handled incorrectly when records were requested in the searchResponse. This
2962 will only affect you if you use the frontend-server.
2964 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2965 Test-client will ask for and print GRS1. Ztest will return dummy records
2968 Added Explain encoders/decoders to the service-level API. Untested.
2970 Added Extended Services: Item Order encoders and decoders to the Service-
2971 level API. Untested. We could use a recent copy of the pertinent bits
2972 of the ILL protocol to add those bits.
2974 Added diagnostic format 1 encoders/decoders to the service-level API.
2977 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2978 odr_cons.c, which causes a more correct output.
2980 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2981 was always set to 0 when no records were requested in the searchRequest.
2983 * Added better external-handling. This shouldn't harm old code that
2984 *encodes* externals. It can break code that looks for a
2985 'single-ASN1-type' representation, since those types that are known
2986 are now decoded immediately. Look at the SUTRS sample code in
2987 seshigh.c and client.c. Documentation updated.
2989 Handling of structured records in bend_fetchresponse. Length -1 marks
2990 structured record, type is deduced from format field.
2992 --- 1.0b2 1995/06/27
2993 Fairly quick maintenance release to add SUTRS support.
2995 Fixed handling of SUTRS records in the demonstration client.
2997 * Added format field to the bend_fetchrequest and bend_fetchresponce
2998 structures of the backend API (frontend server). When the record is
2999 returned, the value of the format field is mapped to an OID. The
3000 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3001 of the record. The special value VAL_NONE in the bend_request means
3002 that no specific format was requested by the client. Documentation
3003 updated accordingly. Test server (ztest) will return a fixed dummy
3004 SUTRS record if your client requests SUTRS.
3006 Documentation updated accordingly.
3008 You can now set external libraries and RANLIB support in the top-level
3012 First public release.
