3 ZOOM SRU mode: more aggressive re-connect.
5 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
6 made available as a utility function, declared in <yaz/logrpn.h>
8 rpn2cql_structure() supports proximity nodes (except that the Type-1
9 proximity node's "exclusion" binary is ignored, as there is no way to
10 express that in CQL). Fixes bug #4564.
14 Fix SEGV that could occur if set command of zoomsh was given without
17 Fix SEGV that could occur if unsupported transport was given for
18 COMSTACK - say https (when SSL was unavailable).
20 Build yaz-url on Windows too.
24 New utility to get web content. Header is url.h. A command line tool
25 yaz-url is part of the distribution and packages.
27 Fixes for SSL COMSTACK (when gnutls is in use).
29 New functions yaz_base64{encode,decode}. Header is base64.h.
33 ZOOM C includes HTTP response buffer as additional info if it fails
34 to decode the SRU response.
36 Make wrbuf_json_puts available.
40 zoom: throw diagnostic for invalid value for option "sru". Before a
41 bad SRU request was sent.
43 Adding new utility wrbuf_vp_puts.
45 Add cclxmlconfig.obj to win/makefile. It was missing completely.
49 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
50 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
51 redirect was used at the same time.
53 MARC line mode decoding: be less picky about length given - first
54 5 digits of header that is.
56 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
58 Changes to decoding of SRU records: a record with recordPacking=xml is
59 modified with a new root element <yaz_record> if the recordData contains
60 multiple children elements. This is to make the record XML parseable
63 RPN to SOLR conversion: encode special characters.
65 Generic Frontend Server: fix uinitialized member, stepSize.
69 Fix a bug in SRU decoding of records.. The database records stored
70 had un-initialized memory, but it would only be seen with yaz_record_render
73 Fix a bug in ccl_qual_dup introduced in 4.2.3.
77 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
81 Add new utilities to convert from CQL to CCL . These utilities have
82 prefix cql_to_ccl defined in cql.h.
84 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
85 lead to memory heap corruptions when ICU utilities were in use.
89 Make compilation work without Libxml2.
91 yaz-client: remove redundant blanks in display of searchResult-1 term
96 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
97 resulting CQL node (tree) in a new node CQL_NODE_SORT.
99 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
100 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
101 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
102 Note that the CQL sortby spec is only converted when the GFS is already
103 converting from CQL to RPN (cql2rpn element).
105 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
106 specify whether to collapse delimitors or not. The existing nmem_strsplit
107 do collapse (collapse parameter = 1).
109 Windows installer: For NSIS, set InstallDir depending on x86/x64.
111 Rename internal func yaz_use_attribute_create. While non-static, this
112 function is not declared in a public header.
116 Add -lCrun when linking with ICU on Solaris.
118 More quicks character set conversions for OPAC records.
122 fix problem with record_render: records were converted (character set
123 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
127 SRU: add methods for handling DADS SRU-proxy facets.
129 Separate OPAC record character set for ZOOM_record. yaz_record_render
130 allows a character set given as charset=from/opacfrom,to where 'from' is
131 the character set of a bibliographic record, 'opacfrom' is character set
132 of OPAC record and 'to' is the target character set.
136 yaz-client: show may XML format records. Command show followed by 'format'
137 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
140 src/stemmer.c: Avoid using unnamed union. It is not supported by some
143 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
146 Update yaz.spec to operate on both SLES11 / Centos 5.5.
148 RPM: Release includes 'indexdata' name. Use indexdata in release name so
149 this package can be distinguished from other vendors.
151 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
152 as determined by configure
154 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
156 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
157 returns no error and no record, the present request is considered
158 partial (only a subset of the records could be returned by backend), and
159 so it is appropriate to set Present Status to partial-4.
163 Move yaz-config man pages to section 1.
165 More documentation about SOLR.
167 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
168 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
169 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
170 peers on some Linux systems. However, in general that does not work
171 so YAZ can not rely on that to work. Debian changed behavior in this
172 respect from Debian lenny to Debian squeeze (still testing as of Oct
174 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
176 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
180 Fix yaz-config output: echo_source not set correctly by configure.
184 SOLR WebService support for yaz-client and ZOOM.
186 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
188 --- 4.0.12 2010/08/17
190 Z39.50 facet support. Facet specifications are passed for search in
191 other-information with ASN.1 as defined in facet.asn and OID
192 .10.1000.81.5 . Facets are expressed as an Attribute list as known
193 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
194 3 is limit (number of entries to get in response). yaz-ztest returns
195 dummy facets if a client asks for them.
197 --- 4.0.11 2010/07/09
199 CCL fixes: bug 2895 and bug 3539.
201 GR1-display: add comma in display - was removed by mistake in
204 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
206 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
208 --- 4.0.10 2010/06/18
210 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
211 result set from a connection. The result set will be on its own
212 thereafter; no operations on it will perform retrievals from a target.
213 Only cached copies are returned.
215 ZOOM C:fix case for HTTP servers responding with Connection:close.
216 Ensure that if there is a current task it is resumed (like fetching
217 more records in a result set) . Bug #3484.
219 PQF parser: use odr_atoi for Odr_int (not atoi)
221 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
222 values that contain any non-digits are treated as string attributes
223 (previously decoding only checked for leading character ([0-9]). PQF
224 encoding: attribute string values are not surrounded by double-quotes.
228 New utility for managing threads - thread_create.h.
230 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
231 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
232 but YAZ' implementation do.
234 Fixes for yaz_cond-functions on Windows 7.
236 DLL export more symbols.
238 zoomsh: show record do NOT render opac.
240 Remove *.la files from Debian and RPM packages.
244 Debian package libyaz-dev depends on libgnutls-dev again (was
245 removed in YAZ 4.0.6, but due to Libtool it is still needed
246 even though yaz-config do not list libgnutls libs).
248 ZOOM: Use only one WRBUF for returning string results for
249 ZOOM_resultset. Reduces memory usage for ZOOM in general.
251 ZOOM: ZOOM_connection do not use a shared pointer to
252 ZOOM_resultset after ZOOM_resultset is destructed by
253 user. Reverts to YAZ 4.0.4 behavior.
257 record-conv: fix problem with at least one XSL conversion -
258 due to probably incorrect usage of XML XSL documents.
262 Fix yaz-config for static mode and the use of SSL (gnutls).
266 Forward decl timeval struct in mutex.h and gettimeofday.h.
268 yaz-config: fix 'static' mode linking.
272 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
273 are wrappers for pthreads or Windows. For Windows these are put in
274 a separate DLL: yaz_cond4.
276 libyaz.la (whole source) is compiled with thread. If thread support
277 is enabled enabled, all source of YAZ is compiled with treading support.
278 This allows core utilities such as yaz_log to use thread facilities.
279 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
280 thread utilities. This commit moves mutex utilities (mutex.c) from
281 libyaz_server.la to libyaz.la.
283 yaz-json-parse displays leading text until error.
287 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
288 patch from Giannis Kosmas.
290 SRU: no longer URL encode SRU database. The URL for an SRU server is
291 a URL and such is alreeady encoded - at least when given with leading
292 http:// or https://. This reverts behavior to YAZ 3.0.50.
294 Support for new MARC XML notation TurboMARC which like MARCXML is a
295 complete representation of MARC/ISO2709.. This one, however, is more
296 compact and allows for faster processing with XSLT. TurboMARC can be
297 used in the marcdisp.h API, from the yaz-marcdump utility and from
300 yaz-ztest can be configured - via the database - to perform certain
301 delays when it performs operations search, present and single record
302 fetch. This allows testers to make yaz-ztest act as a real or even slow
303 Z39.50 server. Refer to the yaz-ztest man pages for details.
307 wrbuf_destroy allows NULL WRBUF passed to it.
309 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
311 Add ZOOM_connection_close.
313 No fixed size buffers for ZOOM shell - bug #3257.
315 tstodr: make it work on s390 platform.
317 New icu iterator-functions. The new icu_iter-functions makes it possible
318 to use ICU chains from many threads.
320 yaz-client: better syntax check for show command.
324 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
327 New simple local-file XML include facility which allows file glob-patterns.
328 Refer to yaz/xml_include.h.
330 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
333 ZOOM_record_get supports new parameter "format" which makes it format XML
336 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
337 JSONText in ECMA-262) is JSONValue, not JSONObject.
341 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
342 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
344 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
345 POSIX/Unix builds .so with major version 4.
347 Remove old LOG_-defines from log.h. They have been obsolete and
348 undefined by default for the last 5 years.
350 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
352 GFS: Remove socket (int *fd) from search_rr handler. The socket
353 descriptor ptr is a facility that allowed a search handler to supply
354 a socket which would serve as a callback - when search was complete.
355 This facility has now been in use for years.
357 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
358 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
359 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
360 returns 'const char *' rather than 'char *. The returned string is
361 read-only and should not be modified by applications. COMSTACK cs_close is
362 now a void function - it no longer returns int. No applications check for
363 the value and the implementations has always returned 0.
365 ZOOM: use size_t for scan hit counts and str size. Functions
366 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
367 occ (hit count) and len (string length) are now of type size_t pointer
368 rather than int pointer. This is to be able to represent large hit counts
369 and to also just to use the proper type for string length (strlen result).
371 New JSON parser. Refer to include/yaz/json.h .
373 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
374 Used to be int in some cases. Many wrbuf_-functions used to return an int
375 indicating some length.. These return values were never used. And so they
378 ODR: odr_malloc, odr_total now takes size_t for size.
380 clone_z_type: fix leak; occurred for encoding failures.
382 --- 3.0.52 2009/12/03
384 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
385 bug was introduced in 3.0.51.
387 --- 3.0.51 2009/12/02
389 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
391 tcpip comstack: fix leak for getaddrinfo.
393 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
394 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
395 Decoding of SRU "path" database is performed by private function
396 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
397 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
399 yaz-client: honor base command for SRU. Change when database setting
400 is applied for SRU and ensure it is kept when a connection is reset.
401 Change also the way errors are displayed or SRU (decoding of packages).
403 --- 3.0.50 2009/11/02
405 Add support for extra request / response data for SRU codecs and GFS.
406 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
407 for extra data response buffer and length. For the GFS, both request
408 and response data (XML) is carried in extra_args and extra_response_data
409 for the search handler. Patch by Ko van der Sloot.
411 ZOOM: For queries that cannot be converted to the specified rpnCharset,
412 ZOOM now returns a diagnostic on the client-side ('invalid query' /
413 10010). This fixes bug #2113.
415 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
416 cmdfile included a 'quit' command that would result in a memory violation.
418 --- 3.0.49 2009/10/01
420 Make a number of functions defined in xmlquery.c static. These have
421 never been declared in a public header file (yaz/xmlquery.h) and was
422 made public by mistake.
424 Improve speed of character conversions (iconv utilities). This makes
425 conversions from MARC-8 faster.
427 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
428 unless type desired is "raw". This will prevent type "xml" from
429 returning ISO2709 .. Which obviously can not be XML parsed.
431 Fix memory leak in ZOOM that would occur if option apdulog was used
432 on a re-used connection.
434 Frontend server logs HTTP requests.
436 Frontend server now sends Z39.50 close when it times out (sesssion has
437 been idle for too long). Versions 2.0.30 and earlier also sent close.
438 But due to a mistake this was disabled in all versions after that, i.e.
439 the server would just close the socket immediately.
441 yaz-client emits a better message when receiving an unrecognised
442 userInformationField.
444 Skip zero-length subfields when decoding ISO2709. This rare case happens
445 if a record has two FS characters in a sequence. Without this patch
446 there would be a reference beyond char array in using_code_len fragments
449 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
451 --- 3.0.48 2009/08/28
453 The show command offered by the zoomsh command now takes a 3d optional
454 parameter type which is what is passed to ZOOM_record. If the type
455 argument is omitted, "render" is used.
457 RPN to CQL conv may use USE string attributes (bug #2978).
459 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
461 --- 3.0.47 2009/07/08
463 Function yaz_xml2query allows a diagnostic element in the PQF XML
464 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
465 code and additional info respectively.
467 The BER BOOLEAN is now the integral type Odr_bool which still happens
468 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
469 typedef'd to Odr_int. This is still an integral 'int', but it may be
470 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
471 ASN-1 compiler as well as programs has been updated to use the new types.
473 --- 3.0.46 2009/06/08
475 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
476 only the bibliographic record was rendered. For type=opac, an OPAC
477 record is only returned if it is present.
479 iconv: small fix for encoding of advancegreek.
481 yaz-client: avoid double display of SRU/SRW records (bug #2798).
483 yaz-client: option auto_reconnect=on really reconnects.
485 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
487 server: avoid null ptr ref for for yaz_poll errors.
489 build: fix RPM build for RHEL 5.3.
491 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
493 --- 3.0.45 2009/03/31
495 Fixed bug #2709: TCP connect returns Invalid argument.
497 Fixed compilation for mingw.
499 Honor charset for raw records (ZOOM_record_get).
501 Fixed use of errno for threaded mode that was seen on Solaris 10.
503 Fixed argument passing with blanks in value for Windows Service.
505 Disable YAZ' own log rotate by default (no 1 GB limit).
506 The variable l_max_size which specifies the log file limit is set to 0
507 (DISABLED): This is due to the fact that YAZ is most often deployed using
508 logrotate. Also YAZ can not perform log rotate because of unsufficient
509 permissions (setuid).
511 --- 3.0.44 2009/02/17
513 List supported encodings in man page for yaz-iconv.
515 Fixed missing SSL libs for --libs output
517 Re-established OID record syntax application-xml. Nobody should use it
518 but we don't want to change soname because of this symbol being absent.
520 --- 3.0.42 2009/02/02
522 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
524 Added member named_result_sets for init handler struct for the GFS. This
525 allows a server to disable named result sets.
527 Removed OID record syntax application-xml.
529 Added support for rule-based transliterator for ICU wrapper of YAZ.
531 Fixed bug #1902: yaz-icu XML output.
533 Make YAZ checks Emacs friendly.
535 BITSTRING value shows value. Bug #2346.
537 ISO2709 decoding: skip control characters from indicator data.
539 Omit sort key by default in yaz-icu's output.
541 Allow combined single char options (again) for YAZ' options function.
543 Utility yaz-marcdump got option to display YAZ version (-V).
545 Allow YAZ to use ICU 3.4.
547 Added new ICU test case which illustrates removal of diacritics.
549 --- 3.0.41 2008/12/29
551 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
553 --- 3.0.40 2008/12/29
555 For configure, using option --without-xml2 also disables Libxslt/Libexslt
558 Fixed bug #2352: yaz-marcdump crashes for certain record.
560 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
562 Added support for Danmarc2 to UTF-8 conversion.
564 Added support for ISO5426 to UTF-8 conversion.
566 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
567 implementation version.
569 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
571 --- 3.0.38 2008/11/10
573 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
574 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
576 ZOOM C now interprets databaseName option for ZOOM connection as path
579 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
581 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
583 Dummy Libxml2 types no longer defined in headers of YAZ'.
585 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
588 --- 3.0.36 2008/09/26
590 Various ODR chapter fixes.
592 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
594 Added missing source for Windows compilation, mutex.c.
596 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
598 For SRU connections in ZOOM all records up to "count" are now fetched.
600 Fixed crash in generic frontend server (and yaz-ztest) which occurred
601 in Windows due to bad error handling for Libxml2.
603 Added facility for sending arbitrary records (ASN.1 any) using
604 ZOOM C's Extended service update. Patch by Sam Reynolds.
606 New options for ZOOM C's connection, logapdu which makes ZOOM log
609 --- 3.0.34 2008/06/18
611 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
613 --- 3.0.32 2008/06/12
615 Fixed memory violation that could occur when decoding UTF-8. This bug
616 was only present in 3.0.30 of YAZ.
618 --- 3.0.30 2008/06/06
620 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
621 GNU TLS is used by default (if found).
623 yaz-ztest returns OPAC records if a client asks for OPAC.
625 Improved speed of MARC-8 encoding.
627 Added support for lossy and loss-less MARC-8 encoding.
629 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
631 Added new Windows Service wrapper (sc).
633 yaz-client's itemorder command may now send a file.
635 Fixed yaz-marcdump to allow the use of NS prefix for record element.
637 Added new function yaz_log_xml_errors.
639 Allow (but warn) unknown XML attributes in MARCXML parsing.
641 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
643 The UTF-8 to MARC-8 conversion now uses a different set of characters
644 for Greek symbols. Bug #2120.
646 --- 3.0.26 2008/02/21
648 Added yaz_daemon (daemon.h).
650 Fixed bug #2068: pkg-config trouble
652 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
654 --- 3.0.24 2008/01/28
656 Document --with-xml2 option.
658 Added OPAC XML XSD (etc/opacxml.xsd).
660 Allow glob mask for name attribute in retrieval element for the
661 generic frontend server's retrieval facility.
663 Changed yaz_poll_poll to return yaz_poll_except for all returned events
664 except POLLIN/POLLOUT.
666 Fixed error handling in cs_listen. Bug #2037.
668 --- 3.0.22 2008/01/20
670 Fixed version in yaz/yaz-version.h.
672 Fixed bug #2027: Crash when closing connection.
674 Changed configure so that ICU support is only enabled if only ICU
675 and Libxml2 is available (because the ICU chain is XML based).
677 --- 3.0.20 2008/01/15
679 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
680 is built. Only this DLL depends on the ICU runtime.
682 yaz-ziffy is no longer part of YAZ. It is distributed separately by
683 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
685 Changed license of CCL module to 'Revised BSD'. After consultation with
686 remaining members of the original EUROPAGATE consortium, we are re-issuing
687 the CCL module without a separate license. The software was developed by
688 Index Data as part of a research project. The special license was included
689 to help feed usage information back to the project consortium to support
690 project evaluation. At this time, the project consortium has long-since
691 disbanded, and the majority of the original principals have retired. At the
692 same time, we have significantly modified the software during the following
693 years, to the point where very practically no original code remains. To
694 simplify re-use of the software, we have contacted those members of the
695 consortium who could be reached, and agreed to re-issue the module as a
696 proper part of the YAZ package.
698 Tcl scripts uses /usr/bin/tclsh as preferred shell.
700 CQL closer to being version 1.2 compliant. CQL also allows free-form
701 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
704 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
705 bug could make Extended services handling crash in the ZOOM layer. This
706 bug was only present in YAZ 3.0.18.
708 --- 3.0.18 2007/12/19
710 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
713 yaz-marcdump reads and writes collection wrapped records.
715 Handle OPAC for record conversion module.
717 Fixes for ICU wrapper.
719 Allow ICU libs to be controlled with --with-icu .
721 --- 3.0.16 2007/11/12
723 Added yaz_poll which is a wrapper for select/poll. When poll is available
724 and non-buggy, it is used, by yaz_poll . This allows more than 1024
725 sockets to be in use.
727 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
728 functionality through an XML based configuration (ICU chain). This system
729 is useful for search facilities such as Pazpar2 and Zebra that needs to
730 perform tokenization of indexed material. The ICU code in a separate
731 library libyaz3_icu.a.
733 Added HTTP tunnel facility for COMSTACK, bug #1752.
734 This is a facility that allows a Web proxy, such as squid, to tunnel
735 Z39.50 traffic. This facility is "transparent" to must applications
736 using YAZ. It's enabled by using pseudo transport connect: followed by
737 the proxy address, followed by command, then follwed by he regular
738 "virtual" addresss. For example,
739 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
741 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
743 --- 3.0.14 2007/09/21
745 Fixed bad memory reference in ZOOM_record - cuased by member not being
746 initialized. This was a problem only in YAZ 3.0.12.
748 Fixed bug in conversion from MARC to XML: Non-XML characters in control
749 fields were not removed.
751 Changed the way C code is generated from codetables.xml. Made a MARC-8
752 conversion trie for each characterSet section rather than codeTable.
753 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
754 of codetables.xml from Larry Dixson, LOC. Bug #1464.
756 --- 3.0.12 2007/09/12
758 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
759 from ZOOM_record_error).
761 ZOOM C function ZOOM_record_get returns record schema for type="schema".
763 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
765 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
767 Better SRW-to-Bib-1 diagnostic mapping.
769 ZOOM C and yaz-client announces SRU version 1.2 by default.
771 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
774 Fixed in yaz_sru_decode to allow other version than 1.1.
776 --- 3.0.10 2007/08/22
778 Added support for SRU scan for ZOOM.
780 Added support for the use of the older versions or Extended Service
781 Update in ZOOM. To faciliate this, an option "updateVersion" may be
782 set to the version , 1=first, 2=second, 3=third. The third version is
783 what ZOOM C has used so far. And that, obviously, is the default.
785 Added support for CCL queries in Z39.50 queries sent to the GFS (and
786 therefore in Zebra and in SimpleServer-based applications). The new
787 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
788 qualifier file used to transform incoming CCL queries into Type-1 RPN,
789 which is passed into the back-end search callback function.
791 Added support for HTTP Basic authentication in clients: the SRU/W
792 codec encodes the username/password elements of the PDU structure
793 appropriately, and these may be set using the "user" and "password"
794 options in ZOOM-C applications (the same options that are used for
795 Z39.50 authentication).
799 Fixed bug #1208: SSL appears to be broken in ZOOM.
801 Fixed bug #1206: Libxml2 include path weirdness.
803 Added oid_name_to_dotstring.
805 Allow elementSetName to be specified for ZOOM C record update.
807 Allow waitAction to be specified for ZOOM C based for Extended Services.
809 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
810 syntax OID. Bug introduced in YAZ 3 series.
812 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
816 Fixed bug #1157: yaz-client does not read .yazclientrc from current
817 directory. yaz-client now reads commands from file given by option -f
818 if specified; then tries to read .yazclientrc in current directory.
819 Failing that, it reads .yazclientrc from user's home directory.
821 Added support for correlationInfo Note and ID for Record Update via
824 Added yaz-client command querycharset which specifies character set for
825 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
826 (termListAndStartPoint).
828 Charset ISO5428:1984 is an alias for ISO5428-1984.
830 Implemented a way to perform scan in a result set using Z39.50. This
831 is achieved by attaching the result set name in the characterInfo
832 (type InternationalString) of OtherInformation in the Scan Request PDU.
833 The result set is identified in the otherinformation by the new OID:
834 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
835 This allows for scan in result set and faceted search . Zebra did some
836 of this in the APT term using attribute type 8 and value being result
837 set. Using the OtherInformation approach for this is cleaner and easier
838 to work with in proxies and the like. This facility can be used in
839 yaz-client using new command setscan which takes a result set as first
840 argument, start position (APT) as second.
842 Changed decoding of SRU XML packed records to deal with servers that
843 have recordData with XML data with multiple root nodes. Also make
844 comparison for recordPacking case insensitive. Again, one server
845 returns "XML" where others return "xml".
847 For SRU responses allow Content-Type application/xml as well as text/xml.
851 Fixed bug in character set conversion of BER strings. Bug introduced
856 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
858 For OID class, use oid_class consistently.
860 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
863 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
864 character set for bibliographic information interchange". By Giannis Kosmas.
866 Added documentation on new OID API.
870 Changes to generic frontend server interface: added new member
871 'query_charset' for bend_initrequest structure. A backend init handler
872 should set this member to its native character set for query terms.
873 When defined, the frontend server logic will announce this character set
874 to a client if the negotiationModel bit is set by the client. All server
875 implementors are encouraged to specify this. If a backend server does not
876 specify this a warning is issued using yaz_log(YLOG_WARN,..).
878 Added CCL utility to remove terms (stop words) from resulting RPN
879 tree. This is handled by functions with prefix ccl_stop_words_ .
881 New ZOOM C option, "rpnCharset", which allows client-side conversion of
882 terms in RPN queries.
884 Clean-up the CCL API. Moved some internal structures from ccl.h to
885 private header cclp.h. Changed ccl_parser_create so that a Bibset must
886 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
887 This is replaced by ccl_parser_find_str which takes a string instead.
889 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
890 libyaz.la is the core of YAZ except the generic frontend server and
891 does not depend on POSIX threads anymore. libyaz_server.la is the
892 generic frontend server facilities and uses POSIX thread functionality
893 if available. The libyaz.la no longer depends on POSIX threads because
894 the number of global structures is limited. NMEM no longer re-uses blocks
895 between threads ; it simply free's memory immediately but allocates in
896 "large" chunks as usual. We don't expect any performance penalties
897 because of this. The yaz_log system is still using a global log_level so
898 caution must be taken when modifying it with yaz_log_init_.. +
899 yaz_log_mask_str. This, however, should not cause any trouble because
900 these functions are called during initialization of application code
901 anyway. `yaz-config --libs server` returns libs for server applications;
902 `yaz-config --libs` returns libs for non-server applications.
904 New OID database - with public definitions in oid_db.h. Removed old OID
905 database including the head oid.h and definitions such as enum oid_value
906 and struct oident. The new OID database uses the same string names as
907 before but the 'protocol' is gone. There are now only two representations
908 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
909 converts from string to OID; functions with prefix yaz_oid_to_string
910 converts the other way.
912 Change to emit_term() in CQL-to-PQF query translation: when a term has
913 the /regexp relation modifier, do not process it for leading and
914 trailing "^" and "*", which have quite different meanings in regular
917 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
918 write handlers no longer carries a 'last' parameter. This will make
919 yaz_iconv flush "less" characters. A flush is performed by call to
920 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
922 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
923 removed, because function yaz_query_to_wrbuf does the same.
925 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
926 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
928 Deprecated MARC utility functions removed.
930 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
933 Branch split: YAZ_2_1_55_branch
935 --- 2.1.54 2007/03/16
937 Fix to ZOOM-C so that transparent reconnection is properly handled on
938 connections that are in asynchronous mode.
940 Fixed compilation on OpenBSD 4.0.
942 Large strings in GRS-1 records are now properly displayed in yaz-client.
944 Added character conversion support for "advancegreek"; based on patch from
947 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
948 sequence is met. Before the error was not set so it would be unknown.
950 Adjust yaz-marcdump MARC reader so that it skips until record separator
953 --- 2.1.52 2007/03/07
955 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
956 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
957 fd_set structure used as a bitmask for the FDs to be selected on.
959 Using ACX_PTHREAD macro to check for POSIX threads.
961 Fixed have-vsnprintf check.
963 --- 2.1.50 2007/02/23
965 Fixes for configure on BSD. Bug #900.
967 Added snprintf/vsnprintf wrappers for systems that don't have
968 limits (heavens forbid).
970 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
971 created before all previous tasks were completed and removed from the
972 task queue, the new task could be removed by a mistake.
974 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
976 Implemented pass-through CQL-to-PQF conversions. Bug #861.
978 Fixed bug #832: Problem with MARC/charset in yaz-client.
980 Fixed bug #668: save command line history for yaz-client.
982 Fixed bug #830: pkg-config support.
984 --- 2.1.48 2007/01/23
986 Extended ZOOM result set options with two options that may be read by
987 a client: resultSetStatus and presentStatus with values as specified for
989 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
991 Fixed bug #827: Using SSL fails on Debian etch.
993 Fixed bug #826: Weird looking chars for set of MARC records.
995 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
996 that is treated as an ItemOrder with itemRequest being an XML document
997 external. The value of "doc" is the content.
999 Extended the GFS search facility. New member of bend_search_rr
1000 'estimated_hit_count' signals that hits is known to be an estmate
1001 (higher or lower than real hit count). New member 'partial_resultset'
1002 signals that the search was partial (hit count is lower or equal than
1003 real hit count). For Z39.50, the information is stored in resultSetStatus
1004 member of SearchResponse APDU. For SRU, the information is signalled
1005 via SRU diagnostic 59: "Result set created with valid partial results
1008 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1010 --- 2.1.46 2007/01/13
1012 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1014 Added ZOOM_connection_peek_event.
1016 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1017 the following new functions:
1018 ZOOM_event_nonblock, ZOOM_connection_process,
1019 ZOOM_connection_get_{socket,mask,timeout},
1020 ZOOM_connection_fire_event_{timeout,socket}.
1021 The existing blocking event handler, ZOOM_event, is a wrapper for the
1022 + blocking ZOOM_event_sys_{poll,select}.
1024 Implemented function ccl_xml_config which parses XML version of CCL
1025 configuration (bug #798).
1027 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1029 Added timings utility (yaz/timing.h)
1031 --- 2.1.44 2007/01/03
1033 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1036 Fixed bug #779: Rotation of apdu.log fails.
1038 Fixed for character set conversions:
1039 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1040 Honor G1 set in MARC-8 decoding.
1042 --- 2.1.42 2006/12/17
1044 Fixed bug #775: char conversion does not handle Alternative UTF-8
1047 Implemented function yaz_marc_read_line which parses MARC line format
1048 records. There is a wealth of formats out there. So far, this function
1049 reads line records produced by yaz_marc_write_line.
1051 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1052 more generic and easier to remember(!) options: -i format and -o format
1053 which specifies input format and output format respectively - where
1054 format is one of "marc", "marcxml", "line", "marcxchange".
1056 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1057 does not print anything except warnings for records.
1059 For yaz-marcdump, added support for MARC split into files (-s) with a given
1062 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1063 spec, at http://www.loc.gov/standards/sru/record-update/
1064 This has changed the binary layout of the following structs:
1065 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1066 bend_update_rr . Patch by Ko van der Sloot.
1068 Added GFS utility function bend_assoc_is_alive which returns 1 if
1069 association is still alive (client is connected); 0 otherwise (client
1070 closed connection). This allows busy servers to stop working for
1073 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1074 been a separate piece of software. This version of ziffy has been modified
1075 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1077 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1079 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1080 Client code may now interrogate options such as "init_opt_sort" to
1081 find out whether the server claims to support various options.
1083 --- 2.1.40 2006/11/27
1085 Added utilities yaz_{set,get}_esn to set/get element set name from
1088 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1089 of YAZ and has been so since YAZ 2.1.10.
1091 Implemented ZOOM_record_error which returns error information for
1092 record (surrogate diagnostic).
1094 --- 2.1.38 2006/10/31
1096 Updates for SRU Update by Ko van der Sloot:
1097 1. Changed name from "operation" to "action"
1098 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1099 versions in the code, marked as 'backward compatible'.
1100 3. Added diagnostics for SRU Update.
1102 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1104 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1106 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1108 For GFS, fixed problem with SRU diagnostic 'First record position out of
1109 range' being issued for 0 hits.
1111 zoomtst10 part of Windows Build.
1113 --- 2.1.36 2006/10/13
1115 Implemented yaz_filepath_comp which splits a path into file path
1116 components (required by Zebra 2.0.3+).
1118 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1119 BSD inspired license until now so this should not have any real impact on
1120 anybody. See http://www.opensource.org/licenses/bsd-license.php
1122 Fixed bug #687: Missing log lines.
1124 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1127 Fixed bug #689: SRU diagnostics to be added.
1129 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1130 whether a connection is idle (no more work do do).
1132 --- 2.1.34 2006/10/04
1134 Change type of optval from long to int for invocation of setsockopt with
1135 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1137 Added support for specifying the max log file size for the Generic
1138 Frontend Server. The size is given with option -r.
1140 --- 2.1.32 2006/09/21
1142 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1144 --- 2.1.30 2006/09/17
1146 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1149 Fixed bug in Generic Frontend Server that could cause a server to stop
1150 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1152 For the generic frontend server, the maximum record size is used as maximum
1153 size of incoming packages (SRU + Z39.50). The value until was previously
1154 only used in Z39.50 Init negotiation and, later, in a session controlled
1155 sizes of records returned. This is controlled using -k option. It can be
1156 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1158 --- 2.1.28 2006/09/04
1160 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1163 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1165 New option for yaz-marcdump -lpos=value which allows setting a portion
1166 of MARC header to a certain value.
1168 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1170 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1171 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1173 --- 2.1.26 2006/08/15
1175 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1178 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1180 --- 2.1.24 2006/08/08
1182 Fixed MARC ISO2709 encoding routines to deal with character set
1185 Minor changes to GFS logging. Database included in search request log
1188 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1189 cached/multiple records.
1191 Shared libraries are built by default on Unix+configure.
1193 Changed cql2pqf transformation to use a different evaluation order. The
1194 new order is: always, relation, structure, position, truncation, index
1195 and relationModifier. Old order was: always, relation, relationModifier,
1196 structure, index, position, truncation. Note that the the latter ones
1197 override former ones for identical attributes.. The new scheme means that
1198 it is possible to override any existing attribute with a relationModifier.
1199 And also that it is possible to override everything for the index rule
1200 (except the ones listed in relationModifier). No order is perfect but this
1201 one, we believe, covers more real cases.. The "always" should have been
1202 called "default", since the attributes there can be overridden with all
1205 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1206 compilation phase, but also for yaz-config --cflags output. This allows
1207 us to have public headers with Libxml2 stuff in them . It should also,
1208 eventually, make Libxml2 checks redundant in packages using YAZ, such
1211 --- 2.1.22 2006/06/15
1213 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1214 stored in uri, message and details.. Previously diagnostics were stored
1215 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1216 compatibility.. but he's probably the only one affected, so.
1218 Added support for CCL, compiled on the client side, in ZOOM-C. This
1219 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1220 input; the resulting query objects can be used for for searching with
1221 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1223 YAZ' configure searches for OpenSSL by default.
1225 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1226 SL_CTX_use_certificate_file. See
1227 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1228 for more info. Thanks to Ko van der Sloot.
1230 --- 2.1.20 2006/06/02
1232 Bug #600: SRU GET, POST support for yaz-client. Introduced
1233 command 'sru' which selects method SOAP/GET/POST.
1235 Allow missingValueAction to be specified for the sortspec string -
1236 function yaz_sort_spec. By default, the missing value action is null.
1237 Use ! to specify "abort". Use = followed by stringvalue to specify default
1240 Ensured that Present-handler (if defined) is called in GFS before any call to
1241 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1242 searchRetrieve requests.
1244 Documentation for YAZ is now based on the Docbook XML/XSLT using
1245 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1246 is no longer depending on jade/openjade or docbook-to-man scripts.
1247 PDF is no longer part of the distribution - but can optionally be
1248 made using DSSSL/jadetex or FOP.
1250 Added retrieval handling support in Generic Frontend Server to support
1251 conversion between MARC/XML as well as XSLTtransforms. See
1252 etc/yazgfs.xml for an example.
1254 Added Authentication support to Generic Frontend Server in SRU
1255 mode. Authentication using HTTP Basic is supported, as is the use
1256 of 'x-username' and 'x-password' parameters in the request itself.
1258 Added support for a new character set MARC8s identical to MARC8 except
1259 that it converts combined characters to single Unicode characters in the
1260 Latin-1 range (when possible).
1262 --- 2.1.18 2006/04/24
1264 ASN.1 compiler 0.4: generates brief Doxygen file header for
1265 generated .h/.c files.
1267 Utility yaz_iconv now supports conversion to MARC-8.
1269 New facilities for the MARC module. The reading - and writing of
1270 content are separate methods for the yaz_marc_t handle. The following
1271 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1272 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1273 format). Write functions have prefix yaz_marc_write_.. The existing
1274 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1275 available. Removed support for OAI-MARC and simplexml (not the
1276 simplexml from PHP5).
1278 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1279 to be returned for this connection.
1281 --- 2.1.16 2006/03/31
1283 Allow multiple languages and charsets to be specified with
1284 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1285 negcharset iso-8859-1,utf-8
1287 Translation of proximity nodes from CQL into PQF now works.
1289 Moved to automake 1.8, 1.9.
1291 Added function yaz_log_set_handler which allows a log handler to be
1292 installed. This handler will be called for all log messages. Output
1293 to file is also produced; but that can be disabled by passing NULL
1294 fname to yaz_log_init_file.
1296 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1298 For SRW (including GFS), accept application/soap+xml as content-type
1301 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1302 produces NO stylesheet reference even if a default stylesheet is specified
1305 --- 2.1.14 2006/03/14
1307 Updated Windows package to include yazd.dll + yazd.lib for the
1308 Development component.
1310 If the environment variable YAZ_LOG is set, then it is used as a
1311 string indicating the default level of logging to use if not
1312 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1313 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1314 used as before. So, for example, to omit warnings from YAZ logging,
1315 export YAZ_LOG=-warn
1317 cql_transform() now map structure and other attributes before indexes,
1318 so that index-specific structures and other attributes can override
1319 defaults. So now a combination of mapping specifications such as:
1321 index.dc.date = 1=date-modified 4=5
1322 does the right thing.
1324 cql_transform() now also respects the "always" mapping specification,
1325 which establishes an initial set of attributes to be used for all
1326 terms except where overridden by more specific attributes associated
1327 with the index, relation or modifier.
1329 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1330 which mode to use; one of "post", "get" or "soap" (SRW, default).
1332 Fixes for yaz_iconv routines: changed trie-based character set conversions
1333 to use only non-negative values for bit fields due to Sun's C compiler not
1334 supporting negative values.
1336 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1337 sequences where not read correctly. Fix by Rustam Usmanov.
1339 Updated win/makefile to use options, settings which makes things
1340 compile with VS C 2005.
1342 --- 2.1.12 2006/02/01
1344 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1346 In ZOOM socket code, use select instead of poll on MacOSX.
1348 ZOOM-C now support client-side compilation of CQL into RPN that is
1349 sent to the server, enabling CQL to be used against all Z39.50
1350 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1351 ZOOM_query object, and submit it using ZOOM_connection_search().
1352 The CQL-to-RPN translation uses a configuration file, the name of
1353 which must be specified in the Connection's "cqlfile" option.
1355 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1356 function, which takes as its start-term parameter a ZOOM_query object
1357 (which may have had either CQL or RPN set into it).
1360 --- 2.1.10 2005/11/29
1362 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1363 GFS to support this as well. Backend handler, bend_srw_update, does the
1364 update work. Code contributed by Ko van der Sloot.
1366 Allow retrieval of Search Result-1 information in ZOOM by the use of
1367 options that are attached to a result set. ZOOM documentation updated
1370 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1371 UTF-8 conversion. Patch by Raj Patel.
1373 Added option -m to GFS to control formatting of timestamps in log file.
1375 Added 'exit' as synonym for 'quit' in yaz-client
1377 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1378 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1379 for the new members. Patch by Ko van der Sloot.
1381 Added support for SRU POST. It is supported for content-type
1382 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1384 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1385 Instead make the library libyaz.la multi-threaded. Threading as a whole
1386 can still be disabled by configure option --disable-threads. Previosly,
1387 with older GLIBCs there were problems with MT libs under Apache. This
1388 has now been fixed a long time ago.
1390 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1393 CQL module modified to be case insensitive for relations/indexes/operations.
1395 Fixed bug in CQL transform code: incorrect value relationModifieder
1398 Added 'show all' command for yaz-client which retrieves all results
1401 Added new yaz-client, xmles, which takes a (private) OID and
1402 a document to be sent as an extended service request.
1404 Describe new yaz-client commands wait_response and set_auto_wait.
1406 Increase TCP/IP listener backlog from 3 (which I am guessing was
1407 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1408 that the socket will queue as many incoming connections as it's able
1409 to handle ongoing connections. In other words, it will never now
1410 refuse a connection that it would be able to handle merely because
1411 it's not got around to accepting() enough of the pending connections
1412 yet. This is the behaviour anyway under Linux, where the listen()
1413 argument is ignored; but not under BSD and on systems such as
1414 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1415 YAZ-based servers should now be uniform across operating systems in
1418 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1419 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1420 This allows yaz-marcdump to read large MARC batches (>2 GB).
1422 Modified all YAZ source files - except the source which is auto-generated
1423 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1426 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1427 corresponding to the existing *_setl() function. These allow option
1428 values containing arbitrary valuues.
1430 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1431 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1432 except that it returns an indicator of whether or not the sort
1433 criterion was accepted (0 for OK, -1 for invalid).
1435 --- 2.1.8 2005/06/07
1437 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1438 MARC output rather than returning "new" buffer.
1440 yaz-client warns about unknown init options.
1442 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1444 --- 2.1.6 2005/05/24
1446 Added support for SRW sort in Generic Frontend Server. Patch
1447 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1448 sortKeys - or NULL if none is provided.
1450 Fixed bug #307: It was impossible to specify indefinite/no timeout
1451 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1454 Added support for multiple languages and charsets to be specified in
1455 ZOOM. Each charset/language is separated by a blank. If negotiation is
1456 in effect in init-response, Option
1457 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1458 Code based on patch by Vasiliy Osadchuk.
1460 Fixed bug #306: infinite recursion that occurred when calling
1461 yaz_log_level_init as the first call (before other log level or
1464 Fixed bug in scan handling in front end server: if preferred-Position-In-
1465 Response was non-present, a NULL pointer referece was performed.
1467 --- 2.1.4 2005/04/26
1469 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1470 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1471 now defined for all those error codes. So instead of putting 109 in
1472 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1473 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1475 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1478 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1480 Program yaz-client now exits and produces an error message if multiple
1481 Z39.50 servers are specified on the command line (none or one allowed
1484 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1487 --- 2.1.2 2005/03/16
1489 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1491 Fixed bug #272: Preserve spacing for CCL terms.
1493 --- 2.1.0 2005/03/14
1495 Added support for virtual hosts and multiple backend servers for
1496 the YAZ frontend server. The configution is XML based and
1497 support specificition of CQL to RPN mappings and explain information.
1498 See section "Virtual Hosts" in the YAZ manual.
1500 Extended OPAC display utility. OPAC display utility renders
1501 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1502 to supplement yaz_marc_decode_wrbuf.
1504 Fixed a bug in MARC decoder that could caused it to crash for some
1505 invalid MARC records. More diagnostics and warnings where added in
1506 XML output (warnings, etc are stored in comments).
1508 --- 2.0.34 2005/02/08
1510 Fixes for UNIX domain sockets. Bug #261.
1512 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1514 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1515 Added yaz_marc_subfield_str which defines subfield lead string which is
1516 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1517 yaz_marc_endline_str which defines end of fields string used in
1518 YAZ_MARC_LINE format. Default string is newline.
1520 Experimental support for MarcXChange. This format can be produced
1521 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1522 http://www.bs.dk/standards/MarcXchange.xsd
1524 Added yaz-client commands scansize that sets maximum number of
1525 entries to be returned by scan.
1527 --- 2.0.32 2005/01/11
1529 Added support for SRW scan in yaz-client and Generic Frontend Server.
1531 * Added whereInList member to SRW Scan Term.
1533 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1535 Fixed NMEM system to return aligned blocks on the smallest boundaries
1536 that are suitably aligned for all possible types on the particular
1537 architecture YAZ is being built for.
1539 --- 2.0.30 2005/01/04
1541 Fixed numerious warnings that was issued with newer versions of GCC.
1543 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1544 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1547 Make YAZ Generic Frontend Server slightly faster.
1549 Enhance (and reduce) logging for Generic Frontend Server.
1551 Revert YAZ log system so that it flushes every write operation
1552 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1554 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1555 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1556 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1557 will effectively disable old definitions.
1559 --- 2.0.28 2004/11/09
1561 Added yaz_log_time_format which specifies log format using
1564 Added yaz_log_module_level which returns mask for a module. Value
1565 is non-zero mask a if module is enabled; zero if disabled.
1567 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1568 in include/yaz/cql.h.
1570 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1572 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1574 Fixed bug #172: RPM builds does not enable SSL.
1576 Doxyfile.in part of dist. Doxyfile generated by configure.
1578 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1579 are given and the corresponding component does not exist.
1581 Extend CCL documentation in YAZ reference. Describe r=r.
1583 --- 2.0.26 2004/10/01
1585 Fixed MARC->MARCXML conversion to properly deal with
1586 fields, subfields, indicators having non-ASCII characters.
1588 Fixed MARC->MARCXML conversion so that ASCII control characters
1589 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1592 Added YAZ GFS support for conversion from Z39.50 surrogate
1593 diagnostics to SRW surrogate diagnostics.
1595 Bug fix: YAZ GFS did not return schema in explainResponse.
1597 --- 2.0.25 2004/09/30
1599 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1600 now converts recordSchema to elementSetName as well as schema URI.
1602 Fixed bug in COMSTACK that prevented HTTP request packages from being
1605 --- 2.0.24 2004/09/29
1607 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1608 does not require white-space before and after the dash in a range, e.g.
1609 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1612 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1613 due to new GCC removing "redundant" code.
1615 Added yaz-client commands scanpos and scanstep that sets preferred
1616 position and step-size for scan.
1618 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1620 Added CCL utility ccl_qual_buf which parses one or more CCL
1621 spec lines in a buffer.
1623 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1624 of name and value - ignoring empty lines and comments.
1626 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1628 Added odr_get_element_path which returns current element path for an
1629 ODR handle. This utility is useful in error handling or user-defined
1632 Added ODR_PRINT utility odr_set_stream which is is a more generic
1633 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1634 to a write function and pointer to close function. The close function - if
1635 non-NULL - will be called during odr_destroy.
1637 Fixed bug in CCL parser where truncation char was not removed from
1638 right side when truncation=both was in effect.
1640 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1643 --- 2.0.23 2004/08/11
1645 Fix buffer overrun in CQL parser when dealing with proximity (%).
1647 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1648 to UTF-8/UCS conversion is now only based on codetables.xml.
1650 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1652 --- 2.0.22 2004/08/06
1654 Add support for more "commit changes" in ZOOM (uses Extended Services).
1656 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1659 Yet another small fix for configure of SSL.
1661 --- 2.0.21 2004/05/14
1663 Fix SSL libs for configure when --with-openssl=DIR is given.
1665 --- 2.0.20 2004/05/10
1667 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1669 SSL comstack now uses yaz.pem certificate file on server side
1670 by default. Certificate filename can be configured by calling
1671 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1673 Fix bug regarding multiple calls to ZOOM_connection_connect.
1675 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1677 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1678 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1680 ZOOM now allows inspection of X509 peer certificate for verification.
1681 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1683 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1684 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1685 as "modular" but it simplifies things.
1687 Added cs_get_peer_certificate to that returns peer X509 PEM.
1689 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1690 NULL if SSL is unavailable.
1692 Documentation about MARC decoding tools.
1694 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1696 --- 2.0.19 2004/03/30
1698 Rename CHANGELOG to NEWS to follow GNU style packing.
1700 Fix bug with missing initialization of member in init_diagnostics.
1701 This bug affects threaded version of GFS server.
1703 --- 2.0.18 2004/03/20
1705 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1708 Ensure zlib.dll is packed with Windows install.
1710 --- 2.0.17 2004/03/17
1712 Fix encoding of xsd:string to use text instead of CDATA.
1714 Fix endless loop in CQL parser with unbalanced ".
1716 Use a more compact way to store MARC-8 conversion tables.
1718 --- 2.0.16 2004/03/16 Debian only
1720 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1723 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1728 --- 2.0.15 2004/03/01
1730 Another fix for decoding of XML packed records.
1732 --- 2.0.14 2004/02/25
1734 Fixes for Chunked encoding. White space not ignored after length spec.
1736 Update NS and use default NS for SRW diagnostic elements.
1738 --- 2.0.13 2004/02/23
1740 Implement ZOOM_resultset_cache_reset which resets record cache.
1742 Implement ZOOM_resultset_sort which sorts a result set.
1744 Implement chunked HTTP transfer.
1746 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1748 --- 2.0.12 2004/02/16
1750 Added member 'schema' to bend_explain_rr structure so that backend
1751 can specify explain record identifier. Defaults to Zeerex 2.0.
1753 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1755 --- 2.0.11 2004/02/16
1757 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1760 Added init command for yaz-client which sends "extra" init request.
1762 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1763 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1765 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1767 Make ZOOM error code for "invalid query".
1769 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1771 --- 2.0.10 2004/02/05
1773 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1776 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1778 Added option -p <file> to make Generic Frontend Server to write PID file.
1780 Added option -D to put Generic Frontend Server in background on its own.
1782 Make ZOOM C recognize option "password". If unset, "pass" is used
1783 (for backwards compatibility).
1785 Fixed a bug in Generic Frontend Server that could make it crash if a
1786 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1789 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1790 Must be issued before open, in order to be in effect.
1792 --- 2.0.9-6 2004/01/12 Debian/Windows
1794 Make the SRU server more picky WRT unknown params, etc.
1796 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1798 New YAZ client command, options, that sets Z39.50 options.
1800 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1801 options from a string of tokens (one token for each option bit).
1803 Update SRW diagnostic code messages.
1805 --- 2.0.9-5 2004/01/07 Debian/Windows
1807 Handle user defined stylesheet for SRW/SRU.
1809 --- 2.0.9-4 2004/01/06 Debian/Windows
1811 Fix bug in decoding of Content-Length.
1813 --- 2.0.9-3 2004/01/06 Debian/Windows
1815 Fix a bug with decoding of XML packed records.
1817 --- 2.0.9-2 2004/01/05 Debian only
1819 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1821 Fix bug in SRW/SRU diagnostics decoding.
1823 --- 2.0.9 2004/01/05
1825 Fixed bug in Generic Frontend Server which could drop records exceeding
1826 preferred message size. Reported and fixed by Irina Dijour.
1828 Fixed calculation of package size for structured records in Generic
1829 Frontend Server. Reported and fixed by Irina Dijour.
1831 Fixed namespace for SRW/SRU diagnostics.
1833 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1835 --- 2.0.8 2003/12/22
1837 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1838 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1841 CQL changes to reflect recent changes to the specification:
1842 * Documentation talks about context sets instead of index sets.
1843 * Documentation talks about indexes instead of qualifiers.
1844 * The CQL-to-PQF transformer's configuration file now uses
1845 "index.set.name = <attributes>" instead of the old form
1846 "qualifier.set.name = <attributes>". (Both forms are still
1847 understood but the latter is deprecated.)
1848 * CQL terms with no explicit index specified are now interpreted as
1849 cql.serverChoice instead of srw.serverChoice (which of course
1850 behaves exactly the same.)
1852 --- 2.0.7 2003/12/16
1854 MARC conversion can now generate ISO2709 output in another
1855 character set. yaz-marcdump uses this facility if you invoke it
1858 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1859 functions from there can be used from C++.
1861 --- 2.0.6 2003/12/04
1863 Frontend server now transfers memory from decoded packages to stream
1866 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1867 references to show up.
1869 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1870 the ZOOM Abstract API. The older names for the same options are still
1871 also supported for the benefit of old applications.
1873 ZOOM-C supports "implementationId" and "implementationVersion" options
1874 to go along with "implementationName". These allow the user code to
1875 specify identification strings to be sent to servers.
1876 Add OID for the new ExtLite attribute set.
1878 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1879 as requested/supplid by Ere Maijala <ere@atp.fi>
1881 For generic frontend server, reverse the order of
1882 "toolkit-supplied / application-supplied" strings sent as implementationId,
1883 Name and Version. Also, remove the spaces around the slash. This brings
1884 the GFS in line with the behaviour of ZOOM-C on the client side.
1886 Add function ZOOM_scanset_display_term.
1888 yaz-client shows scan displayTerm if present.
1890 Utility yaz-iconv is now installed by default along with the man page
1893 Extend configure check for OpenSSL to use pkg-config where available (such
1896 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1897 server to specify uid/gid/mask for socket using the format
1898 unix:[user=uid,][group=gid,][umask=mask,]file=path
1899 If file= is omitted the existing format is assumed, e.g.
1901 in which case the mask is 0666 (rw for everybody).
1903 Major restructure of YAZ source. All source in libyaz is in src directory.
1904 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1905 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1907 Added man page for utility yaz-marcdump (used to be called marcdump).
1908 yaz-marcdump is installed by 'make install'.
1910 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1911 of incoming package failed.
1913 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1915 Change prototype of odr_perror: add const to message string.
1917 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1919 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1920 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1921 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1922 DNS lookup. There should not be any compatibility problems with this
1923 assuming that blocking=1 or 0 is used.
1925 Fix bad reference in UNIX comstack in function cs_addrstr.
1927 Fix for compilation on AIX.
1929 The generic front-end server (server/seshigh.c) now supports returning
1930 Init diagnostics to the client in User-information-field, in
1931 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1934 --- 2.0.4 2003/09/04
1936 Allow any CQL relation (not just all,any,exact,scr).
1938 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1939 that features the same UI.
1941 Implemented command update0 in YAZ client which is equivalent to
1942 update but uses old of Ext Update ASN.1.
1944 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1945 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1946 Previously no OID was used for this info.
1948 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1949 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1950 returns 'malformed search term' otherwise.
1952 SortResponse member resultCount now set to NULL in sort handler of
1955 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1958 Add three new utility functions for translating OIDs between various
1959 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1960 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1961 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1962 char *oid_to_dotstring(const int *oid, char *oidbuf);
1963 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1965 Reverted modifications for ES Update definition for z_IU0Update
1966 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1967 is back to YAZ 2.0.2.
1969 String value attributes for CCL parser.
1971 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1972 which their FirstSearch server returns in Init responses, sometimes
1973 carrying useful diagnostic information when Init fails. This has the
1974 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1975 "z39.50/oclcui.asn", where its definition is somewhat different from
1976 what OCLC document on their web-site, as required to interoperate with
1979 Support for anonymous authentication in yaz-client. Use the command
1982 * Fix the OID of the Index Data-local "admin" Extended Service from
1983 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1984 the 1000, which indicates a locally-defined OID, was a mistake.
1986 --- 2.0.3 2003/06/20
1988 Fix CCL directive @case handling so that it affects string match for
1989 both CCL keywords and qualifiers.
1991 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1992 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1993 Decoder has been updated with ASN.1 changes as listed in
1994 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1995 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1996 z_IUUpdate, remains unchanged.
1998 ZOOM_record_get may now return a record in a specific character set.
1999 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2000 "from" is the character set of record as returned by target. "to" is
2001 the character set to be returned. If omitted, "to" is UTF-8.
2003 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2005 New ODR utility, odr_getelement, which returns name of element for
2006 which encoding/decoding failed.
2008 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2009 in cases where a required element was omitted.
2011 Bug fix: some MARC8 sequences were not converted.
2013 New ZOOM option "step" which specifies number of records to be
2014 retrieved in one chunk. Used in conjunction with "start" and "count".
2016 SRW support for yaz-client. Use scheme http: to use it, e.g.
2019 yaz-client no longer does (un)intelligent character set conversions
2020 by default. Can be enabled with charset and marc_charset commands.
2022 xmalloc trace fix for 64-bit systems such as DEC alpha.
2024 Solaris 2.6 compile fix.
2026 New function, cql_strerror() translates SRW error codes, as returned
2027 by cql_transform_error(), into human-readable English strings. Used
2028 in yaz-client diagnostics when appropriate.
2030 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2031 converts it into a type-1 query which is sent to the server. This
2032 makes CQL available for use with all Z-servers, as opposed to the tiny
2033 minority that can handle CQL queries themselves.
2035 --- 2.0.2 2003/04/28
2037 New Debian package layout similar to the Redhat Package layout.
2039 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2040 and search result respectively.
2042 --- 2.0.1 2003/04/25
2044 Redhat package is now several packages: libyaz (runtime libraries),
2045 libyaz-devel (development and documentation, and yaz (utility programs).
2046 Package spec file by Morten Bogeskov.
2048 New member 'schema' in struct bend_fetch_rr which the name of requested
2049 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2050 handler MAY set this to reflect the schema of the returned record.
2052 New member 'display_term' in struct scan_entry. GFS now sets member entries
2053 and allocates scan entries to be filled by user scan handler. In previous
2054 version, entries member was allocated by the scan handler. That still works,
2055 but the GFS will ignore member display_term - assuming it was NOT set by
2056 the handler. The fact that the GFS now allocates the entries both allows
2057 for new members and makes a scan handler easier to write.
2059 Fix CQL lex buffer overflow.
2061 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2062 SRU default recordPacking is string.
2064 SRU protocol support for frontend server.
2066 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2068 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2070 Added scan for the ZOOM shell (zoomsh).
2074 * String Identifers for Schemas (Amendment 5).
2075 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2076 Old definition for schema
2077 Odr_oid *schema; /* OPT */
2082 Z_InternationalString *uri;
2083 #define Z_Schema_oid 1
2084 #define Z_Schema_uri 2
2087 * resultCount parameter to Sort Response (Amendment 1).
2088 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2090 Support for SRW 1.0 over HTTP. This is an optional feature and
2091 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2094 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2095 on the same port. SRW SearchRetrieveRequests are mapped
2096 to bend_init,bend_search,bend_fetch,bend_close.
2098 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2100 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2101 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2103 ZOOM connections are SRW based if schem http is used for hostname
2104 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2105 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2107 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2108 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2109 distance=n, order=true/false, relation=le, prox unit=word. If
2110 n is omitted, distance 1 is used.
2112 Fixed problem with C compiler include path in wrong order.
2114 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2115 on Solaris. Patch from Ko van der Sloot.
2117 New MARC decode API. All new functions operate on a yaz_marc_t
2118 handle. The most important new functions are: yaz_marc_create,
2119 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2120 decode and destroy respectively. Decoder can produce formats
2121 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2122 include/yaz/marcdisp.h.
2124 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2125 to UTF-8, UCS-32, wchar_t or Latin-1.
2127 * Prototypes for yaz_iconv_-functions moved to separate header
2128 include/yaz/yaz-iconv.h.
2130 Make a few private functions 'static' in unix.c. This prevents
2131 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2133 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2134 are set when Init Response is received.
2136 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2137 but returns diagnostic set as well.
2139 New function yaz_strerror which is a portable wrapper for
2140 strerror/strerror_r/GetLastMessage.
2142 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2143 is returned for MARC. If type is "oai", then OAI MARC is returned.
2145 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2148 --- 1.9.2 2002/11/26
2150 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2152 Fix bad race conditions on SIGTERM and terminate gracefully in
2155 Move retrieval (data1) module to Zebra since nobody seems to be
2158 Add GRS-1 render for ZOOM using same format as yaz-client.
2160 --- 1.9.1 2002/10/05
2162 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2164 Fix broken ESpec handling in data1 module.
2166 SGML reader parses comments and makes them part of the data1 tree.
2168 Added several type casts so that YAZ compiles as C++ code.
2170 ZOOM didn't handle PDU encoding failures properly.
2172 Added more Bib-1 diagnostics (approved extensions).
2174 GNU configure: better check for iconv.
2176 More portable use of accept, getpeername. Check for socklen_t. Use
2177 int/size_t if socklen_t is not defined.
2181 PQF parser rejects bad queries - including those with extra
2182 characters in them. PQF parser used to silently ignore that.
2183 Cleaner API for PQF added, which allows you to get detailed
2184 error information for bad queries (see yaz/pquery.h).
2186 Fixed bug in ZOOM_record_get for type "database".
2188 Implemented mini iconv library supporting conversions between
2189 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2191 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2193 --- 1.8.9 2002/08/20
2195 Fixed ZOOM C record cache so that preferredRecordSyntax and
2196 elementSetName is used to check for already fetched records.
2198 --- 1.8.8 2002/08/02
2200 Added three members in bend_initrequest structure to facilitate
2201 character set negotiation.
2203 Fixed a bug in frontend server that could cause indefinite
2204 loops under rare conditions.
2206 Revised character set utilities (charneg.h) so that encoding
2207 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2209 For PQF, directive @term <type> sets term type for Scan/Search.
2210 Here <type> is general, string, numeric, null. The term type
2211 is inherited - just like @attr.
2213 New call odr_set_charset that sets character set conversion for
2214 international-strings on a ODR stream. Prototype is:
2215 int odr_set_charset(ODR o, const char *to, const char *from);
2216 The InternationalString is still represented as C string in YAZ
2217 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2218 won't). On the protocol level, you can use any encoding.
2220 Support for UNIX sockets in ZOOM.
2222 Solaris recv sometimes returns errno == ENOENT. It is treated as
2223 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2225 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2226 both client and server. Code by Morten Bogeskov.
2228 --- 1.8.7 2002/05/22
2230 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2231 that they can be used directly from Visual Basic. You must recompile
2232 your windows APP if you're using ZOOM.
2234 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2235 Commands "lang" and "charset" sets language and character set respectively.
2236 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2237 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2239 Attributes from multiple CCL fields may be OR'ed rather than merged
2240 using directive "@field or". Fields are still merged by default -
2241 equivalent to "@field merge".
2243 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2246 Fixed bug in zget for parameter ExtendedServicesResponse.
2250 --- 1.8.6 2002/03/25
2252 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2254 Client displays USR.1:SearchResult-1 (hits per term).
2256 Additional Search Info for search in Generic Frontend Server.
2258 Fixed CCL parsing of "field=s".
2260 WIN32 installer - using the excellent NSIS software from nullsoft.
2262 Fixed CCL parsing of "field = - <number>".
2264 Added function yaz_marc_decode that decodes MARC for line mode
2265 display or XML (similar to that used by JZKit).
2267 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2268 Z39.50. But ISO/ILL was, however.
2270 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2271 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2273 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2274 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2276 --- 1.8.5 2002/02/03
2278 New YAZ client features: Command completion and new commands:
2279 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2280 Code provided by Jacob Poulsen.
2282 New call oid_trav, that visits all registered OIDs via callback.
2284 Function ZOOM_record_get now returns const char pointer rather than
2285 void pointer. It saves a lot of type casts.
2287 For YAZ client, command "auth" now allows you to set authentication
2288 in IdPass style. It is enabled when three tokens are given - order
2289 is user, group and password.
2291 Fix memory leaks in MARC record handling for ZOOM.
2293 New option for YAZ client, -k <kilobytes> that sets
2294 maximum record size. Similar to -k option for generic frontend
2295 server and yaz-ztest.
2297 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2299 Prefix query parser reports "fail" when bad attribute set is given.
2301 Fix in MARC decoder. Proximity logging. Fix for attribute set
2302 in scan handler for server. Patches by Shigeru Ishida.
2304 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2307 Configure option --with-openssl=<dir> now works when a directory is
2308 specified. Patch provided by Morten Bogeskov.
2310 New option for YAZ client, -u <auth>, that sets authentication.
2312 ZOOM fix: error information was sometimes "missing", since error
2313 was cleared/reset too when it shouldn't.
2315 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2317 --- 1.8.4 2002/01/04
2319 Scan for ZOOM API. New object ZOOM_scanset. New functions
2320 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2321 ZOOM_scanset_destroy.
2323 New ZOOM function, ZOOM_connection_last_event, that returns type
2324 of last event (such as "receive data", "send data", "apdu received",
2327 New ZOOM option, schema, that specifies schema for retrieval.
2329 New CCL feature. Qualifiers can be aliases for one or more
2330 other qualifiers (if more than one is given, OR is used).
2332 ZOOM uses named result sets if target supports it.
2334 Two new YAZ client commands: . (dot, which sources a script of YAZ
2335 client commands), and ! (to execute shell command.). Implemented
2338 Working on Debian packages.
2340 --- 1.8.3 2001/11/19
2342 YAZ client enables named result sets only if target supports it.
2344 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2346 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2347 with key="host" to get same result.
2349 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2350 Function Z3950_resultset_record(s) returns references to records
2351 "owned" by resultset. To become owner use Z3950_record_clone.
2353 Function z_ext_record handles Extended Services. Thanks to
2356 --- 1.8.2 2001/11/12
2358 CCL Parser fix: ignore token comma when dealing with and-lists.
2360 Documentation updates for COMSTACK.
2362 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2363 Changed prototype Z3950_records. For some functions, int parameters
2364 were changed to size_t.
2366 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2369 New MARC decode/display function, marc_display_exl, which properly rejects
2370 non-ISO2709 records. YAZ client uses it.
2372 --- 1.8.1 2001/10/29
2374 Fix bug: local attribute set wasn't set correctly in PQF strings.
2378 * Old Z39.50 codecs no longer supported.
2380 Added ZOOM C binding. See http://zoom.z3950.org/
2382 Renamed states for COMSTACKs to avoid confusion with events.
2384 Implemented cs_look and proper cs_rcvconnect.
2386 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2388 Configure detects POSIX threads on OpenBSD.
2390 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2391 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2393 When error is returned from present handler, non-surrogate diagnostic
2394 is returned in present response (and fetch handler is no longer called).
2396 * Minor adjustments to pquery parser (PQF). Token characters may be
2397 escaped by using backslash (C-style).
2399 PQF parser allows string attribute values to be specified. For @attr,
2400 non-numeric characters after the equal-sign are treated as strings
2401 (e.g. @attr 9=title).
2403 CCL trunction character may be defined (@truncation in file)
2405 * function zget_ExtendedServicesRequest sets waitAction to
2406 waitIfPossible (was wait).
2408 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2411 CCL operator names may be set in field definition files (CCL_bibset).
2412 See ccl/bib1 for an example.
2414 Fixes in ASN.1 compiler for C++ compatibility.
2416 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2417 and "op_or" to avoid conflict with C++.
2419 Fixed problem with GNU readline detection on Redhat 7.0.
2421 Added step-size for Scan backend handler.
2423 Fixed bug that made the frontend server crash when no attribute
2424 set was specified for scan.
2426 Front-end server automatically switches to original working directory
2427 when installed as an NT service. Previously -w had to be specified to
2430 Added extended attributes for retrieval module (data1), so that data1
2431 records carry d1_readXML/SGML attributes. d1_read also supports
2432 null-data rules ( <tag/>)
2434 On UNIX when POSIX threads are available, a separate library libyazthread
2435 is created. Programmers should link with that library and the yaz library
2436 when using threads. The reason for the split was that some applications
2437 on Linux, such as Apache, doesn't work well when using shared objects that
2440 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2441 (or any frontend server) in SSL mode by specifying ssl: followed by
2442 address. Only tested on UNIX.
2444 Added feature for CCL module. Virtual structure s=al or s=ol generates
2445 and-list and or-list respectively instead of phrase search.
2449 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2450 log_mask_str. This was done to avoid name conflicts with other libraries
2451 (such as other PHP extensions).
2453 Added raw OID member for preferred record syntax (request_format_raw)
2454 and returned record syntax (output_format_raw) for backend fetch method.
2456 Config file yaz-config now accepts options so that it returns specific
2457 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2459 Shared library support for UNIX using GNU libtool.
2461 * Modified backend interface. Request/Response struct's replaced by
2462 one read/write C struct. For example bend_fetchrequest and
2463 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2464 Every handler - even search has to be registered in bend_init
2465 handler. This means that the YAZ library no longer refers to
2466 external functions and it makes it possible to make the whole
2467 thing a single DLL/SO.
2469 Added Segment handler for backend server.
2471 Added Zmbol/Zebra administrative functions to YAZ client.
2473 Threaded frontend server on UNIX (when POSIX Threads are available).
2474 Starting the server with option -T enables multi-threading.
2478 Added configure option --enable-comp/disable-comp to control use
2479 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2480 located in sub directory asn.
2482 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2483 in ${exec_prefix}/bin along with the other programs yaz-client and
2486 GNU automake used to maintain makefiles.
2488 Added several OID's.
2490 Changed retrieval module so that we can load records with no abstract
2491 syntax defined. Tagpaths in these records are fully composed of string
2494 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2498 On UNIX, the generated makefile now supports a proper 'make install'.
2499 The prefix can be set via GNU configure to set the install location
2500 (default is /usr/local).
2502 * YAZ programs client and ztest were renamed to yaz-client and
2503 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2504 locations, such as /usr/bin,/usr/local/bin,etc.
2506 * YAZ Header files were moved from include to include/yaz. YAZ Header
2507 files are referred to as include <yaz/log.h> rather than <log.h>.
2508 The YAZ include path (-I ..) is therefore the same as before. Programmers
2509 should update their #include statements or use -Ipath/include/yaz
2510 instead. The main motivation for doing this change is that YAZ header files
2511 can be installed in "standard" locations /usr/include,/usr/local/include
2512 without introducing conflicts, since ALL YAZ header files are stored
2513 in subdirectory yaz (under /usr/include for example).
2515 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2516 rather than project/workspace files. We switched because project files
2517 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2520 Changed name of logging function, logf, to yaz_log, to prevent name
2521 clash with some math-log functions. The YAZ header log.h defines logf
2522 to yaz_log (#define) so there should be no incompatibilities by this
2525 Added bend_start/bend_stop handlers for server. These handler are
2526 called on start/stop of server. For windows they are called whenever
2527 a service is started/stopped.
2529 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2530 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2531 in util/yc.tcl. The auto-generated C code structures are, in a few
2532 cases, incompatible with the old decoders. There are differences in the
2533 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2534 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2535 The preprocessor variable ASN_COMPILED is defined when the compiled
2536 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2537 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2538 wish to use the old encoders/decoders you can specify --disable-yc
2541 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2542 version so that it supports both new - and old version of DB Update
2544 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2545 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2546 change. The name parameter can be set to 0 in which no name is specified
2547 for the construction. The macros odr_implicit and odr_explicit sets name
2548 parameter to zero for the construction involved. New macros
2549 odr_implicit_tag and odr_explicit_tag are similar to the others,
2550 except that a name parameter is added. For programmers' that don't use
2551 ODR they probably only need to change the call to z_APDU and z_External.
2553 Added access control facility by interfacing the TCP wrapper library.
2554 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2555 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2556 name of the daemon and enables the access control as specified in
2557 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2559 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2560 den Dool <H.M.vdnDool@kub.nl>.
2562 Added reference ID parameter to most functions in server API - refer
2563 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2565 Changed name of ccl library to libccl.a (was ccl.a).
2567 Fixed bug in decoder for Explain (Category TargetInfo).
2569 Added support for GNU readline in client. Thanks to Jacob Poulsen
2570 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2572 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2573 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2574 IMPLEMENTATION! This change was made to the development version before
2575 the ZIG decided to retract the amendment. If any users MUST be
2576 compatible with the original Update definition, PLEASE CONTACT US, and
2577 we will include a separate definition corresponding to the old Update
2578 ES. Note that because of the change to the ASN.1 of the
2579 TaskPackageRecordStructure we cannot define a single structure that
2580 will support both versions.
2582 * Added const modifier to buffer parameter for some ODR/BER encoding
2583 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2584 completeWAIS, odr_dumpBER.
2586 Fixed bug in client.c which caused a crash when a scanResponse didn't
2587 contain positionOfTerm.
2589 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2590 * will cause an error in a client if a non-YAZ target sends both a
2591 * list of Scan entries and non-surrogate diagnostics.
2593 Retrieval module enhancements. Tag sets may be typed in the reference
2594 to it. From the .abs-file the "tagset" directive takes a third optional
2595 integer type for the tag set referenced. From a .tag-file the "include"
2596 directive takes a third optional type as well. The old "type" directive
2597 in the tag set itself is still recognized but acts as the default type
2600 Backend interface change. Individual Scan terms returned from bend_scan
2601 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2602 in include/backend.h.
2604 Retrieval module enhancements. Multiple tag sets and attribute sets may
2605 be specified in abstract syntax specs. Revised the error/warning for
2606 logging messages reported by the retrieval module when reading the
2609 Object Identifier system (oid_..) changed. The API is backwards
2610 compatible but the oid-routines now allocates new OID's when needed.
2611 Raw OID's may be specified in oid_getvalbyname.
2613 YAZ now uses GNU configure to generate Makefile(s).
2615 * Minor changes in some of the member names of DeleteResultSetRequest and
2616 DeleteResultSetResponse. See include/proto.h.
2618 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2619 and added member 'languages' in TargetInfo (which was missing).
2621 Changed the way attribute sets are handled in the retrieval
2622 module. These are now cached, just like the abstract syntaxes
2625 Changed YAZ so that it links with compiled ASN.1.
2627 Added Explain-schema definitions and mapping routines. The following
2628 Explain categories have been implemented: AttributeDetails,
2629 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2631 Fixed minor bug in Windows version of Server Library.
2633 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2635 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2637 Added EXTERNAL: UNIverse Resource Report (non-standard).
2639 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2640 ENUMERATED and SET OF.
2642 * Added 'const' to some of the char pointer arguments for the
2643 functions, data1_read_node, data1_getelementbytagname,
2644 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2647 Fixed bug in data1_insert_taggeddata - the last_child member of
2648 parent wasn't initialised.
2650 * Changed data1_read_record and data1_read_node so that the supplied
2651 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2652 doesn't refer to any parts of the "SGML"-buffer.
2654 Fixed bug in server library (Windows version of statserv_remove).
2656 * Changed code so that it compiles as C++. The type definition
2657 of Odr_fun which is a member of Odr_arm was changed. The result is,
2658 that an explicit typecast is needed for the fun pointer when
2659 using Odr_arm - as in:
2660 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2662 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2664 Implemented the new structured date and time definition as approved
2665 by the ZIG. Added schemaId element to the specificTag in Espec-1
2666 (also approved at the last ZIG). Thanks to RVDM.
2668 Added some Object identifiers (RVDM).
2670 Changed the Update Extended Service (RVDM).
2672 Added command "refid" to client which specifies referenceId for
2673 the following requests.
2675 Implemented extended service handling for server. See ztest.c
2676 for an example as well as backend.h. New handlers are registerd
2677 in the Init handler.
2679 * Changed interface for sort in server.
2681 Added new members to statserv_options_block. It allows a server
2682 to read options from another source than just the command line. Thanks
2683 to Charles Woodfield.
2685 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2686 renamed to zboolean. Some C++ compilers complained about the name.
2688 Minor changes to gils.abs. Added index 's' (sort) on title
2689 and date/time-last-modified.
2691 --- 1.4pl2 1998/1/30
2693 Fixed bug in server library regarding inetd mode (-i). This bug
2694 was introduced by release 1.4.
2696 --- 1.4pl1 1998/1/29
2698 Added sort facility in client and backend server interface.
2700 Fixed problem with dependencies in Makefile(s).
2702 Fixed bugs for encoders/decoders of extended services and
2705 Implemented sub-tree feature for schemas. Sub-trees are
2706 referenced in *.abs-files. See explain.abs for an example
2707 of the use of this feature.
2709 Modified bib1.att; local attributes for ANY didn't include
2710 ANY itself (only affects use of the retrieval module).
2712 Fixed bug in plain SGML reader in function data1_read_node:
2713 tags with prefix "var" was incorrectly interpreted as variants.
2715 Added feature "sub-schemas" to enable references to - and definitions
2716 of - group of elements.
2718 * Removed member parent from type data1_element (in data1.h).
2720 Implemented function odr_nullval() that returns the value of
2723 * Removed member num_children from data1_node (in data1.h).
2725 Made NT service interface part of the server library. The
2726 function statserv_main uses the NT service when required and
2727 calls the statserv_start / statserv_close routines.
2729 Routine zget_SearchRequest and zget_PresentRequest fills
2730 resultSetName/Id member with "default" instead of "Default".
2732 Fixed memory leak in server. Request queue member wasn't freed.
2734 Fixed nmem_exit so that memory is freed.
2738 Revised the CCL parser utility to be thread safe.
2740 Added function, oid_ent_to_oid, to replace the function
2741 oid_getoidbyent, which is not thread safe.
2743 * Added nmem_init and nmem_exit to initialize and release
2744 NMEM resources. Function nmem_init should be called once in the
2745 initial thread before NMEM/ODR is used. statserv.c and client.c
2746 have been changed accordingly. The change was necessary to make
2747 NMEM thread safe. The NMEM memory pool is shared amongst threads
2748 in a process. Unix-based applications will still work fine without
2751 Added NT Services interface for the the Z39.50 (statserv) Server.
2752 Refer to the ztest.c source on the usage.
2754 Windows 95/NT port using MSVC5.0. Project files are included in the
2757 * Defined new 'global' handle for the retrieval (data1) system. The
2758 new handled, data1_handle, describes the state of the data1 system.
2759 This handle is passed as first argument to virtually all
2760 data1 related routines. The functions data1_create and data1_destroy
2761 creates and destroys a data1 handle respectively.
2763 Added ODR encode stream member to all backend request structures
2764 init, search, scan etc. This stream should be used to allocate all
2765 memory used for the response when thread safe operation is needed.
2767 Changed the comstack utility, cs_addstr, to be thread safe. The
2768 returned hostname string returned by the function is now part the
2771 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2772 function. The cs_straddr takes a COMSTACK handle as argument, so this
2773 function must be used after cs_create and before bind/connect.
2774 This function is thread safe.
2776 Moved test server to 'ztest' directory - generic server code still
2777 in 'server' directory.
2779 Made prefix query (pquery.c) utility thread safe.
2781 Added new function modifier YAZ_EXPORT to 'export' public DLL
2782 functions when using windows (see include/yconfig.h).
2784 Added definitions to the OID database (util/oid.c) (RVDM).
2786 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2788 Added call to ccl_rpn_delete in client program.
2790 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2791 release of RPN structure.
2793 Added support for C++, headers uses extern "C" for public definitions.
2794 With input from RVDM.
2796 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2797 Thanks to Ronald van der Meer (RVDM).
2799 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2801 Added support for private extensions to the OID database
2802 (oid_setprivateoids()). Thanks to RVDM.
2804 Added optional, physical ANY (key replication)
2806 Fixed null-reference problem in GRS-1 output filter.
2808 Proximity operator added to Prefix Query Format (PQF).
2810 In test client command "base" accepts multiple databases.
2812 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2816 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2818 Smallish bug-fixes in the new encoders/decoders (explain).
2820 Bug fixed in DeleteRequest.
2822 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2824 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2826 Added SOIF syntax (using private OID for now) to retrieval module and client.
2828 Added Update extended service.
2830 Added SearchResult-1 additional info structure.
2832 Added optional CCL (ISO8777) interpreter as separate module. Available
2835 --- 1.2 1996/6/10 (1st anniversary release)
2837 Added Summary record syntax. Lightly tested.
2839 Added OPAC record syntax. Untested.
2841 Added ResourceReport service encoders/decoders. Untested.
2843 Fixed bug in z_Unit - wrong tagging on unitSystem.
2845 Fixed bug in the DiagRecs decoder.
2847 Added options for max PDU size and session timeout to frontend-server.
2849 Added documentation of query-language parsers and other supporting utilities.
2851 [frontend-server] Added Attribute set to the bend_scanrequest API.
2853 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2854 surrogate diagnostics were generated.
2856 [retrieval] Allow multiple local values for attribute.
2858 [retrieval] Allow multiple attributes per element in .abs files. index type.
2860 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2862 --- 1.1pl2 1996/4/10
2864 Minor changes, mostly specific to Zebra's requirements (retrieval)
2868 Repaired bug in frontend server when running multiple listening
2869 endpoints in dynamic mode.
2871 z_External() now won't break if a known, ASN.1 value comes encapsulated
2872 in an octet-string. The value will pass through unmodified in an Odr_oct.
2874 Added a bit of code to the demo client to decode & display
2875 ASN.1-structured records represented in the octet-aligned branch of
2876 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2878 Added z_ext_getentbyref() to the ASN module. Doc updated.
2880 * Completed the SCAN definition in the ASN module. This may break SCAN
2881 code based on older YAZ-versions at compile-time. The fix is easy -
2884 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2885 under the SCAN definition. Remember to initialize this, server-people.
2887 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2888 that this does not extend to ODR and ASN.
2890 Comstack allows insertion of established socket (primarily for
2891 inetd-operation of servers). Doc updated.
2893 Front-end server can now start from the inetd in TCP mode. Doc
2896 --- 1.0pl4 1996/1/24
2900 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2901 the rank and record number.
2903 Adjustments to the frontend server.
2905 Fixed diagnostic BER dumper. It ignored the file argument.
2909 Various changes to retrieval module.
2911 Changed the union discriminators of the protocol files from enums to
2912 ints paired with #defines.
2914 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2917 *Changed operator in the RPN structure to 'roperator', again to avoid a
2920 Fixed problems in Explain decoders/encoders.
2922 --- 1.0pl2 1995/12/6
2924 Memory bug in log module fixed.
2926 --- 1.0pl1 1995/12/5
2928 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2930 Bug in Explain DatabaseInfo module fixed.
2932 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2936 The shift to v1.0 signals that we now consider the *core* functionality
2937 of YAZ reasonably stable (the core being more or less equivalent to
2938 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2939 tested (Explain not at all - though that will happen soonish).
2941 Minor changes to code to support Windows port.
2943 Various minor changes after we're getting to use GRS-1 & co. more.
2945 Added Espec-1 format.
2947 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2948 of the protocol and it cannot be selected when encoding (maps into 'string'
2949 when decoding). Needed to talk to some servers.
2951 Demo client can request simple element set names.
2953 Added Diagnostic Format encoders/decoders.
2955 Added simple Close handling to frontend server (no hooks for resource
2956 reporting yet), and demonstration client.
2958 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2960 --- 1.0b3 1995/08/24
2962 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2963 handled incorrectly when records were requested in the searchResponse. This
2964 will only affect you if you use the frontend-server.
2966 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2967 Test-client will ask for and print GRS1. Ztest will return dummy records
2970 Added Explain encoders/decoders to the service-level API. Untested.
2972 Added Extended Services: Item Order encoders and decoders to the Service-
2973 level API. Untested. We could use a recent copy of the pertinent bits
2974 of the ILL protocol to add those bits.
2976 Added diagnostic format 1 encoders/decoders to the service-level API.
2979 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2980 odr_cons.c, which causes a more correct output.
2982 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2983 was always set to 0 when no records were requested in the searchRequest.
2985 * Added better external-handling. This shouldn't harm old code that
2986 *encodes* externals. It can break code that looks for a
2987 'single-ASN1-type' representation, since those types that are known
2988 are now decoded immediately. Look at the SUTRS sample code in
2989 seshigh.c and client.c. Documentation updated.
2991 Handling of structured records in bend_fetchresponse. Length -1 marks
2992 structured record, type is deduced from format field.
2994 --- 1.0b2 1995/06/27
2995 Fairly quick maintenance release to add SUTRS support.
2997 Fixed handling of SUTRS records in the demonstration client.
2999 * Added format field to the bend_fetchrequest and bend_fetchresponce
3000 structures of the backend API (frontend server). When the record is
3001 returned, the value of the format field is mapped to an OID. The
3002 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3003 of the record. The special value VAL_NONE in the bend_request means
3004 that no specific format was requested by the client. Documentation
3005 updated accordingly. Test server (ztest) will return a fixed dummy
3006 SUTRS record if your client requests SUTRS.
3008 Documentation updated accordingly.
3010 You can now set external libraries and RANLIB support in the top-level
3014 First public release.
