3 Fix a bug in SRU decoding of records.. The database records stored
4 had un-initialized memory, but it would only be seen with yaz_record_render
7 Fix a bug in ccl_qual_dup introduced in 4.2.3.
11 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
15 Add new utilities to convert from CQL to CCL . These utilities have
16 prefix cql_to_ccl defined in cql.h.
18 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
19 lead to memory heap corruptions when ICU utilities were in use.
23 Make compilation work without Libxml2.
25 yaz-client: remove redundant blanks in display of searchResult-1 term
30 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
31 resulting CQL node (tree) in a new node CQL_NODE_SORT.
33 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
34 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
35 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
36 Note that the CQL sortby spec is only converted when the GFS is already
37 converting from CQL to RPN (cql2rpn element).
39 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
40 specify whether to collapse delimitors or not. The existing nmem_strsplit
41 do collapse (collapse parameter = 1).
43 Windows installer: For NSIS, set InstallDir depending on x86/x64.
45 Rename internal func yaz_use_attribute_create. While non-static, this
46 function is not declared in a public header.
50 Add -lCrun when linking with ICU on Solaris.
52 More quicks character set conversions for OPAC records.
56 fix problem with record_render: records were converted (character set
57 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
61 SRU: add methods for handling DADS SRU-proxy facets.
63 Separate OPAC record character set for ZOOM_record. yaz_record_render
64 allows a character set given as charset=from/opacfrom,to where 'from' is
65 the character set of a bibliographic record, 'opacfrom' is character set
66 of OPAC record and 'to' is the target character set.
70 yaz-client: show may XML format records. Command show followed by 'format'
71 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
74 src/stemmer.c: Avoid using unnamed union. It is not supported by some
77 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
80 Update yaz.spec to operate on both SLES11 / Centos 5.5.
82 RPM: Release includes 'indexdata' name. Use indexdata in release name so
83 this package can be distinguished from other vendors.
85 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
86 as determined by configure
88 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
90 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
91 returns no error and no record, the present request is considered
92 partial (only a subset of the records could be returned by backend), and
93 so it is appropriate to set Present Status to partial-4.
97 Move yaz-config man pages to section 1.
99 More documentation about SOLR.
101 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
102 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
103 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
104 peers on some Linux systems. However, in general that does not work
105 so YAZ can not rely on that to work. Debian changed behavior in this
106 respect from Debian lenny to Debian squeeze (still testing as of Oct
108 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
110 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
114 Fix yaz-config output: echo_source not set correctly by configure.
118 SOLR WebService support for yaz-client and ZOOM.
120 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
122 --- 4.0.12 2010/08/17
124 Z39.50 facet support. Facet specifications are passed for search in
125 other-information with ASN.1 as defined in facet.asn and OID
126 .10.1000.81.5 . Facets are expressed as an Attribute list as known
127 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
128 3 is limit (number of entries to get in response). yaz-ztest returns
129 dummy facets if a client asks for them.
131 --- 4.0.11 2010/07/09
133 CCL fixes: bug 2895 and bug 3539.
135 GR1-display: add comma in display - was removed by mistake in
138 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
140 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
142 --- 4.0.10 2010/06/18
144 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
145 result set from a connection. The result set will be on its own
146 thereafter; no operations on it will perform retrievals from a target.
147 Only cached copies are returned.
149 ZOOM C:fix case for HTTP servers responding with Connection:close.
150 Ensure that if there is a current task it is resumed (like fetching
151 more records in a result set) . Bug #3484.
153 PQF parser: use odr_atoi for Odr_int (not atoi)
155 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
156 values that contain any non-digits are treated as string attributes
157 (previously decoding only checked for leading character ([0-9]). PQF
158 encoding: attribute string values are not surrounded by double-quotes.
162 New utility for managing threads - thread_create.h.
164 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
165 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
166 but YAZ' implementation do.
168 Fixes for yaz_cond-functions on Windows 7.
170 DLL export more symbols.
172 zoomsh: show record do NOT render opac.
174 Remove *.la files from Debian and RPM packages.
178 Debian package libyaz-dev depends on libgnutls-dev again (was
179 removed in YAZ 4.0.6, but due to Libtool it is still needed
180 even though yaz-config do not list libgnutls libs).
182 ZOOM: Use only one WRBUF for returning string results for
183 ZOOM_resultset. Reduces memory usage for ZOOM in general.
185 ZOOM: ZOOM_connection do not use a shared pointer to
186 ZOOM_resultset after ZOOM_resultset is destructed by
187 user. Reverts to YAZ 4.0.4 behavior.
191 record-conv: fix problem with at least one XSL conversion -
192 due to probably incorrect usage of XML XSL documents.
196 Fix yaz-config for static mode and the use of SSL (gnutls).
200 Forward decl timeval struct in mutex.h and gettimeofday.h.
202 yaz-config: fix 'static' mode linking.
206 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
207 are wrappers for pthreads or Windows. For Windows these are put in
208 a separate DLL: yaz_cond4.
210 libyaz.la (whole source) is compiled with thread. If thread support
211 is enabled enabled, all source of YAZ is compiled with treading support.
212 This allows core utilities such as yaz_log to use thread facilities.
213 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
214 thread utilities. This commit moves mutex utilities (mutex.c) from
215 libyaz_server.la to libyaz.la.
217 yaz-json-parse displays leading text until error.
221 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
222 patch from Giannis Kosmas.
224 SRU: no longer URL encode SRU database. The URL for an SRU server is
225 a URL and such is alreeady encoded - at least when given with leading
226 http:// or https://. This reverts behavior to YAZ 3.0.50.
228 Support for new MARC XML notation TurboMARC which like MARCXML is a
229 complete representation of MARC/ISO2709.. This one, however, is more
230 compact and allows for faster processing with XSLT. TurboMARC can be
231 used in the marcdisp.h API, from the yaz-marcdump utility and from
234 yaz-ztest can be configured - via the database - to perform certain
235 delays when it performs operations search, present and single record
236 fetch. This allows testers to make yaz-ztest act as a real or even slow
237 Z39.50 server. Refer to the yaz-ztest man pages for details.
241 wrbuf_destroy allows NULL WRBUF passed to it.
243 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
245 Add ZOOM_connection_close.
247 No fixed size buffers for ZOOM shell - bug #3257.
249 tstodr: make it work on s390 platform.
251 New icu iterator-functions. The new icu_iter-functions makes it possible
252 to use ICU chains from many threads.
254 yaz-client: better syntax check for show command.
258 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
261 New simple local-file XML include facility which allows file glob-patterns.
262 Refer to yaz/xml_include.h.
264 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
267 ZOOM_record_get supports new parameter "format" which makes it format XML
270 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
271 JSONText in ECMA-262) is JSONValue, not JSONObject.
275 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
276 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
278 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
279 POSIX/Unix builds .so with major version 4.
281 Remove old LOG_-defines from log.h. They have been obsolete and
282 undefined by default for the last 5 years.
284 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
286 GFS: Remove socket (int *fd) from search_rr handler. The socket
287 descriptor ptr is a facility that allowed a search handler to supply
288 a socket which would serve as a callback - when search was complete.
289 This facility has now been in use for years.
291 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
292 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
293 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
294 returns 'const char *' rather than 'char *. The returned string is
295 read-only and should not be modified by applications. COMSTACK cs_close is
296 now a void function - it no longer returns int. No applications check for
297 the value and the implementations has always returned 0.
299 ZOOM: use size_t for scan hit counts and str size. Functions
300 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
301 occ (hit count) and len (string length) are now of type size_t pointer
302 rather than int pointer. This is to be able to represent large hit counts
303 and to also just to use the proper type for string length (strlen result).
305 New JSON parser. Refer to include/yaz/json.h .
307 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
308 Used to be int in some cases. Many wrbuf_-functions used to return an int
309 indicating some length.. These return values were never used. And so they
312 ODR: odr_malloc, odr_total now takes size_t for size.
314 clone_z_type: fix leak; occurred for encoding failures.
316 --- 3.0.52 2009/12/03
318 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
319 bug was introduced in 3.0.51.
321 --- 3.0.51 2009/12/02
323 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
325 tcpip comstack: fix leak for getaddrinfo.
327 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
328 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
329 Decoding of SRU "path" database is performed by private function
330 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
331 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
333 yaz-client: honor base command for SRU. Change when database setting
334 is applied for SRU and ensure it is kept when a connection is reset.
335 Change also the way errors are displayed or SRU (decoding of packages).
337 --- 3.0.50 2009/11/02
339 Add support for extra request / response data for SRU codecs and GFS.
340 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
341 for extra data response buffer and length. For the GFS, both request
342 and response data (XML) is carried in extra_args and extra_response_data
343 for the search handler. Patch by Ko van der Sloot.
345 ZOOM: For queries that cannot be converted to the specified rpnCharset,
346 ZOOM now returns a diagnostic on the client-side ('invalid query' /
347 10010). This fixes bug #2113.
349 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
350 cmdfile included a 'quit' command that would result in a memory violation.
352 --- 3.0.49 2009/10/01
354 Make a number of functions defined in xmlquery.c static. These have
355 never been declared in a public header file (yaz/xmlquery.h) and was
356 made public by mistake.
358 Improve speed of character conversions (iconv utilities). This makes
359 conversions from MARC-8 faster.
361 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
362 unless type desired is "raw". This will prevent type "xml" from
363 returning ISO2709 .. Which obviously can not be XML parsed.
365 Fix memory leak in ZOOM that would occur if option apdulog was used
366 on a re-used connection.
368 Frontend server logs HTTP requests.
370 Frontend server now sends Z39.50 close when it times out (sesssion has
371 been idle for too long). Versions 2.0.30 and earlier also sent close.
372 But due to a mistake this was disabled in all versions after that, i.e.
373 the server would just close the socket immediately.
375 yaz-client emits a better message when receiving an unrecognised
376 userInformationField.
378 Skip zero-length subfields when decoding ISO2709. This rare case happens
379 if a record has two FS characters in a sequence. Without this patch
380 there would be a reference beyond char array in using_code_len fragments
383 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
385 --- 3.0.48 2009/08/28
387 The show command offered by the zoomsh command now takes a 3d optional
388 parameter type which is what is passed to ZOOM_record. If the type
389 argument is omitted, "render" is used.
391 RPN to CQL conv may use USE string attributes (bug #2978).
393 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
395 --- 3.0.47 2009/07/08
397 Function yaz_xml2query allows a diagnostic element in the PQF XML
398 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
399 code and additional info respectively.
401 The BER BOOLEAN is now the integral type Odr_bool which still happens
402 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
403 typedef'd to Odr_int. This is still an integral 'int', but it may be
404 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
405 ASN-1 compiler as well as programs has been updated to use the new types.
407 --- 3.0.46 2009/06/08
409 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
410 only the bibliographic record was rendered. For type=opac, an OPAC
411 record is only returned if it is present.
413 iconv: small fix for encoding of advancegreek.
415 yaz-client: avoid double display of SRU/SRW records (bug #2798).
417 yaz-client: option auto_reconnect=on really reconnects.
419 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
421 server: avoid null ptr ref for for yaz_poll errors.
423 build: fix RPM build for RHEL 5.3.
425 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
427 --- 3.0.45 2009/03/31
429 Fixed bug #2709: TCP connect returns Invalid argument.
431 Fixed compilation for mingw.
433 Honor charset for raw records (ZOOM_record_get).
435 Fixed use of errno for threaded mode that was seen on Solaris 10.
437 Fixed argument passing with blanks in value for Windows Service.
439 Disable YAZ' own log rotate by default (no 1 GB limit).
440 The variable l_max_size which specifies the log file limit is set to 0
441 (DISABLED): This is due to the fact that YAZ is most often deployed using
442 logrotate. Also YAZ can not perform log rotate because of unsufficient
443 permissions (setuid).
445 --- 3.0.44 2009/02/17
447 List supported encodings in man page for yaz-iconv.
449 Fixed missing SSL libs for --libs output
451 Re-established OID record syntax application-xml. Nobody should use it
452 but we don't want to change soname because of this symbol being absent.
454 --- 3.0.42 2009/02/02
456 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
458 Added member named_result_sets for init handler struct for the GFS. This
459 allows a server to disable named result sets.
461 Removed OID record syntax application-xml.
463 Added support for rule-based transliterator for ICU wrapper of YAZ.
465 Fixed bug #1902: yaz-icu XML output.
467 Make YAZ checks Emacs friendly.
469 BITSTRING value shows value. Bug #2346.
471 ISO2709 decoding: skip control characters from indicator data.
473 Omit sort key by default in yaz-icu's output.
475 Allow combined single char options (again) for YAZ' options function.
477 Utility yaz-marcdump got option to display YAZ version (-V).
479 Allow YAZ to use ICU 3.4.
481 Added new ICU test case which illustrates removal of diacritics.
483 --- 3.0.41 2008/12/29
485 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
487 --- 3.0.40 2008/12/29
489 For configure, using option --without-xml2 also disables Libxslt/Libexslt
492 Fixed bug #2352: yaz-marcdump crashes for certain record.
494 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
496 Added support for Danmarc2 to UTF-8 conversion.
498 Added support for ISO5426 to UTF-8 conversion.
500 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
501 implementation version.
503 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
505 --- 3.0.38 2008/11/10
507 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
508 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
510 ZOOM C now interprets databaseName option for ZOOM connection as path
513 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
515 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
517 Dummy Libxml2 types no longer defined in headers of YAZ'.
519 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
522 --- 3.0.36 2008/09/26
524 Various ODR chapter fixes.
526 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
528 Added missing source for Windows compilation, mutex.c.
530 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
532 For SRU connections in ZOOM all records up to "count" are now fetched.
534 Fixed crash in generic frontend server (and yaz-ztest) which occurred
535 in Windows due to bad error handling for Libxml2.
537 Added facility for sending arbitrary records (ASN.1 any) using
538 ZOOM C's Extended service update. Patch by Sam Reynolds.
540 New options for ZOOM C's connection, logapdu which makes ZOOM log
543 --- 3.0.34 2008/06/18
545 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
547 --- 3.0.32 2008/06/12
549 Fixed memory violation that could occur when decoding UTF-8. This bug
550 was only present in 3.0.30 of YAZ.
552 --- 3.0.30 2008/06/06
554 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
555 GNU TLS is used by default (if found).
557 yaz-ztest returns OPAC records if a client asks for OPAC.
559 Improved speed of MARC-8 encoding.
561 Added support for lossy and loss-less MARC-8 encoding.
563 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
565 Added new Windows Service wrapper (sc).
567 yaz-client's itemorder command may now send a file.
569 Fixed yaz-marcdump to allow the use of NS prefix for record element.
571 Added new function yaz_log_xml_errors.
573 Allow (but warn) unknown XML attributes in MARCXML parsing.
575 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
577 The UTF-8 to MARC-8 conversion now uses a different set of characters
578 for Greek symbols. Bug #2120.
580 --- 3.0.26 2008/02/21
582 Added yaz_daemon (daemon.h).
584 Fixed bug #2068: pkg-config trouble
586 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
588 --- 3.0.24 2008/01/28
590 Document --with-xml2 option.
592 Added OPAC XML XSD (etc/opacxml.xsd).
594 Allow glob mask for name attribute in retrieval element for the
595 generic frontend server's retrieval facility.
597 Changed yaz_poll_poll to return yaz_poll_except for all returned events
598 except POLLIN/POLLOUT.
600 Fixed error handling in cs_listen. Bug #2037.
602 --- 3.0.22 2008/01/20
604 Fixed version in yaz/yaz-version.h.
606 Fixed bug #2027: Crash when closing connection.
608 Changed configure so that ICU support is only enabled if only ICU
609 and Libxml2 is available (because the ICU chain is XML based).
611 --- 3.0.20 2008/01/15
613 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
614 is built. Only this DLL depends on the ICU runtime.
616 yaz-ziffy is no longer part of YAZ. It is distributed separately by
617 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
619 Changed license of CCL module to 'Revised BSD'. After consultation with
620 remaining members of the original EUROPAGATE consortium, we are re-issuing
621 the CCL module without a separate license. The software was developed by
622 Index Data as part of a research project. The special license was included
623 to help feed usage information back to the project consortium to support
624 project evaluation. At this time, the project consortium has long-since
625 disbanded, and the majority of the original principals have retired. At the
626 same time, we have significantly modified the software during the following
627 years, to the point where very practically no original code remains. To
628 simplify re-use of the software, we have contacted those members of the
629 consortium who could be reached, and agreed to re-issue the module as a
630 proper part of the YAZ package.
632 Tcl scripts uses /usr/bin/tclsh as preferred shell.
634 CQL closer to being version 1.2 compliant. CQL also allows free-form
635 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
638 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
639 bug could make Extended services handling crash in the ZOOM layer. This
640 bug was only present in YAZ 3.0.18.
642 --- 3.0.18 2007/12/19
644 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
647 yaz-marcdump reads and writes collection wrapped records.
649 Handle OPAC for record conversion module.
651 Fixes for ICU wrapper.
653 Allow ICU libs to be controlled with --with-icu .
655 --- 3.0.16 2007/11/12
657 Added yaz_poll which is a wrapper for select/poll. When poll is available
658 and non-buggy, it is used, by yaz_poll . This allows more than 1024
659 sockets to be in use.
661 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
662 functionality through an XML based configuration (ICU chain). This system
663 is useful for search facilities such as Pazpar2 and Zebra that needs to
664 perform tokenization of indexed material. The ICU code in a separate
665 library libyaz3_icu.a.
667 Added HTTP tunnel facility for COMSTACK, bug #1752.
668 This is a facility that allows a Web proxy, such as squid, to tunnel
669 Z39.50 traffic. This facility is "transparent" to must applications
670 using YAZ. It's enabled by using pseudo transport connect: followed by
671 the proxy address, followed by command, then follwed by he regular
672 "virtual" addresss. For example,
673 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
675 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
677 --- 3.0.14 2007/09/21
679 Fixed bad memory reference in ZOOM_record - cuased by member not being
680 initialized. This was a problem only in YAZ 3.0.12.
682 Fixed bug in conversion from MARC to XML: Non-XML characters in control
683 fields were not removed.
685 Changed the way C code is generated from codetables.xml. Made a MARC-8
686 conversion trie for each characterSet section rather than codeTable.
687 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
688 of codetables.xml from Larry Dixson, LOC. Bug #1464.
690 --- 3.0.12 2007/09/12
692 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
693 from ZOOM_record_error).
695 ZOOM C function ZOOM_record_get returns record schema for type="schema".
697 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
699 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
701 Better SRW-to-Bib-1 diagnostic mapping.
703 ZOOM C and yaz-client announces SRU version 1.2 by default.
705 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
708 Fixed in yaz_sru_decode to allow other version than 1.1.
710 --- 3.0.10 2007/08/22
712 Added support for SRU scan for ZOOM.
714 Added support for the use of the older versions or Extended Service
715 Update in ZOOM. To faciliate this, an option "updateVersion" may be
716 set to the version , 1=first, 2=second, 3=third. The third version is
717 what ZOOM C has used so far. And that, obviously, is the default.
719 Added support for CCL queries in Z39.50 queries sent to the GFS (and
720 therefore in Zebra and in SimpleServer-based applications). The new
721 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
722 qualifier file used to transform incoming CCL queries into Type-1 RPN,
723 which is passed into the back-end search callback function.
725 Added support for HTTP Basic authentication in clients: the SRU/W
726 codec encodes the username/password elements of the PDU structure
727 appropriately, and these may be set using the "user" and "password"
728 options in ZOOM-C applications (the same options that are used for
729 Z39.50 authentication).
733 Fixed bug #1208: SSL appears to be broken in ZOOM.
735 Fixed bug #1206: Libxml2 include path weirdness.
737 Added oid_name_to_dotstring.
739 Allow elementSetName to be specified for ZOOM C record update.
741 Allow waitAction to be specified for ZOOM C based for Extended Services.
743 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
744 syntax OID. Bug introduced in YAZ 3 series.
746 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
750 Fixed bug #1157: yaz-client does not read .yazclientrc from current
751 directory. yaz-client now reads commands from file given by option -f
752 if specified; then tries to read .yazclientrc in current directory.
753 Failing that, it reads .yazclientrc from user's home directory.
755 Added support for correlationInfo Note and ID for Record Update via
758 Added yaz-client command querycharset which specifies character set for
759 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
760 (termListAndStartPoint).
762 Charset ISO5428:1984 is an alias for ISO5428-1984.
764 Implemented a way to perform scan in a result set using Z39.50. This
765 is achieved by attaching the result set name in the characterInfo
766 (type InternationalString) of OtherInformation in the Scan Request PDU.
767 The result set is identified in the otherinformation by the new OID:
768 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
769 This allows for scan in result set and faceted search . Zebra did some
770 of this in the APT term using attribute type 8 and value being result
771 set. Using the OtherInformation approach for this is cleaner and easier
772 to work with in proxies and the like. This facility can be used in
773 yaz-client using new command setscan which takes a result set as first
774 argument, start position (APT) as second.
776 Changed decoding of SRU XML packed records to deal with servers that
777 have recordData with XML data with multiple root nodes. Also make
778 comparison for recordPacking case insensitive. Again, one server
779 returns "XML" where others return "xml".
781 For SRU responses allow Content-Type application/xml as well as text/xml.
785 Fixed bug in character set conversion of BER strings. Bug introduced
790 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
792 For OID class, use oid_class consistently.
794 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
797 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
798 character set for bibliographic information interchange". By Giannis Kosmas.
800 Added documentation on new OID API.
804 Changes to generic frontend server interface: added new member
805 'query_charset' for bend_initrequest structure. A backend init handler
806 should set this member to its native character set for query terms.
807 When defined, the frontend server logic will announce this character set
808 to a client if the negotiationModel bit is set by the client. All server
809 implementors are encouraged to specify this. If a backend server does not
810 specify this a warning is issued using yaz_log(YLOG_WARN,..).
812 Added CCL utility to remove terms (stop words) from resulting RPN
813 tree. This is handled by functions with prefix ccl_stop_words_ .
815 New ZOOM C option, "rpnCharset", which allows client-side conversion of
816 terms in RPN queries.
818 Clean-up the CCL API. Moved some internal structures from ccl.h to
819 private header cclp.h. Changed ccl_parser_create so that a Bibset must
820 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
821 This is replaced by ccl_parser_find_str which takes a string instead.
823 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
824 libyaz.la is the core of YAZ except the generic frontend server and
825 does not depend on POSIX threads anymore. libyaz_server.la is the
826 generic frontend server facilities and uses POSIX thread functionality
827 if available. The libyaz.la no longer depends on POSIX threads because
828 the number of global structures is limited. NMEM no longer re-uses blocks
829 between threads ; it simply free's memory immediately but allocates in
830 "large" chunks as usual. We don't expect any performance penalties
831 because of this. The yaz_log system is still using a global log_level so
832 caution must be taken when modifying it with yaz_log_init_.. +
833 yaz_log_mask_str. This, however, should not cause any trouble because
834 these functions are called during initialization of application code
835 anyway. `yaz-config --libs server` returns libs for server applications;
836 `yaz-config --libs` returns libs for non-server applications.
838 New OID database - with public definitions in oid_db.h. Removed old OID
839 database including the head oid.h and definitions such as enum oid_value
840 and struct oident. The new OID database uses the same string names as
841 before but the 'protocol' is gone. There are now only two representations
842 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
843 converts from string to OID; functions with prefix yaz_oid_to_string
844 converts the other way.
846 Change to emit_term() in CQL-to-PQF query translation: when a term has
847 the /regexp relation modifier, do not process it for leading and
848 trailing "^" and "*", which have quite different meanings in regular
851 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
852 write handlers no longer carries a 'last' parameter. This will make
853 yaz_iconv flush "less" characters. A flush is performed by call to
854 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
856 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
857 removed, because function yaz_query_to_wrbuf does the same.
859 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
860 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
862 Deprecated MARC utility functions removed.
864 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
867 Branch split: YAZ_2_1_55_branch
869 --- 2.1.54 2007/03/16
871 Fix to ZOOM-C so that transparent reconnection is properly handled on
872 connections that are in asynchronous mode.
874 Fixed compilation on OpenBSD 4.0.
876 Large strings in GRS-1 records are now properly displayed in yaz-client.
878 Added character conversion support for "advancegreek"; based on patch from
881 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
882 sequence is met. Before the error was not set so it would be unknown.
884 Adjust yaz-marcdump MARC reader so that it skips until record separator
887 --- 2.1.52 2007/03/07
889 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
890 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
891 fd_set structure used as a bitmask for the FDs to be selected on.
893 Using ACX_PTHREAD macro to check for POSIX threads.
895 Fixed have-vsnprintf check.
897 --- 2.1.50 2007/02/23
899 Fixes for configure on BSD. Bug #900.
901 Added snprintf/vsnprintf wrappers for systems that don't have
902 limits (heavens forbid).
904 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
905 created before all previous tasks were completed and removed from the
906 task queue, the new task could be removed by a mistake.
908 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
910 Implemented pass-through CQL-to-PQF conversions. Bug #861.
912 Fixed bug #832: Problem with MARC/charset in yaz-client.
914 Fixed bug #668: save command line history for yaz-client.
916 Fixed bug #830: pkg-config support.
918 --- 2.1.48 2007/01/23
920 Extended ZOOM result set options with two options that may be read by
921 a client: resultSetStatus and presentStatus with values as specified for
923 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
925 Fixed bug #827: Using SSL fails on Debian etch.
927 Fixed bug #826: Weird looking chars for set of MARC records.
929 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
930 that is treated as an ItemOrder with itemRequest being an XML document
931 external. The value of "doc" is the content.
933 Extended the GFS search facility. New member of bend_search_rr
934 'estimated_hit_count' signals that hits is known to be an estmate
935 (higher or lower than real hit count). New member 'partial_resultset'
936 signals that the search was partial (hit count is lower or equal than
937 real hit count). For Z39.50, the information is stored in resultSetStatus
938 member of SearchResponse APDU. For SRU, the information is signalled
939 via SRU diagnostic 59: "Result set created with valid partial results
942 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
944 --- 2.1.46 2007/01/13
946 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
948 Added ZOOM_connection_peek_event.
950 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
951 the following new functions:
952 ZOOM_event_nonblock, ZOOM_connection_process,
953 ZOOM_connection_get_{socket,mask,timeout},
954 ZOOM_connection_fire_event_{timeout,socket}.
955 The existing blocking event handler, ZOOM_event, is a wrapper for the
956 + blocking ZOOM_event_sys_{poll,select}.
958 Implemented function ccl_xml_config which parses XML version of CCL
959 configuration (bug #798).
961 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
963 Added timings utility (yaz/timing.h)
965 --- 2.1.44 2007/01/03
967 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
970 Fixed bug #779: Rotation of apdu.log fails.
972 Fixed for character set conversions:
973 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
974 Honor G1 set in MARC-8 decoding.
976 --- 2.1.42 2006/12/17
978 Fixed bug #775: char conversion does not handle Alternative UTF-8
981 Implemented function yaz_marc_read_line which parses MARC line format
982 records. There is a wealth of formats out there. So far, this function
983 reads line records produced by yaz_marc_write_line.
985 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
986 more generic and easier to remember(!) options: -i format and -o format
987 which specifies input format and output format respectively - where
988 format is one of "marc", "marcxml", "line", "marcxchange".
990 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
991 does not print anything except warnings for records.
993 For yaz-marcdump, added support for MARC split into files (-s) with a given
996 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
997 spec, at http://www.loc.gov/standards/sru/record-update/
998 This has changed the binary layout of the following structs:
999 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1000 bend_update_rr . Patch by Ko van der Sloot.
1002 Added GFS utility function bend_assoc_is_alive which returns 1 if
1003 association is still alive (client is connected); 0 otherwise (client
1004 closed connection). This allows busy servers to stop working for
1007 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1008 been a separate piece of software. This version of ziffy has been modified
1009 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1011 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1013 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1014 Client code may now interrogate options such as "init_opt_sort" to
1015 find out whether the server claims to support various options.
1017 --- 2.1.40 2006/11/27
1019 Added utilities yaz_{set,get}_esn to set/get element set name from
1022 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1023 of YAZ and has been so since YAZ 2.1.10.
1025 Implemented ZOOM_record_error which returns error information for
1026 record (surrogate diagnostic).
1028 --- 2.1.38 2006/10/31
1030 Updates for SRU Update by Ko van der Sloot:
1031 1. Changed name from "operation" to "action"
1032 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1033 versions in the code, marked as 'backward compatible'.
1034 3. Added diagnostics for SRU Update.
1036 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1038 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1040 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1042 For GFS, fixed problem with SRU diagnostic 'First record position out of
1043 range' being issued for 0 hits.
1045 zoomtst10 part of Windows Build.
1047 --- 2.1.36 2006/10/13
1049 Implemented yaz_filepath_comp which splits a path into file path
1050 components (required by Zebra 2.0.3+).
1052 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1053 BSD inspired license until now so this should not have any real impact on
1054 anybody. See http://www.opensource.org/licenses/bsd-license.php
1056 Fixed bug #687: Missing log lines.
1058 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1061 Fixed bug #689: SRU diagnostics to be added.
1063 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1064 whether a connection is idle (no more work do do).
1066 --- 2.1.34 2006/10/04
1068 Change type of optval from long to int for invocation of setsockopt with
1069 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1071 Added support for specifying the max log file size for the Generic
1072 Frontend Server. The size is given with option -r.
1074 --- 2.1.32 2006/09/21
1076 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1078 --- 2.1.30 2006/09/17
1080 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1083 Fixed bug in Generic Frontend Server that could cause a server to stop
1084 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1086 For the generic frontend server, the maximum record size is used as maximum
1087 size of incoming packages (SRU + Z39.50). The value until was previously
1088 only used in Z39.50 Init negotiation and, later, in a session controlled
1089 sizes of records returned. This is controlled using -k option. It can be
1090 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1092 --- 2.1.28 2006/09/04
1094 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1097 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1099 New option for yaz-marcdump -lpos=value which allows setting a portion
1100 of MARC header to a certain value.
1102 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1104 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1105 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1107 --- 2.1.26 2006/08/15
1109 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1112 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1114 --- 2.1.24 2006/08/08
1116 Fixed MARC ISO2709 encoding routines to deal with character set
1119 Minor changes to GFS logging. Database included in search request log
1122 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1123 cached/multiple records.
1125 Shared libraries are built by default on Unix+configure.
1127 Changed cql2pqf transformation to use a different evaluation order. The
1128 new order is: always, relation, structure, position, truncation, index
1129 and relationModifier. Old order was: always, relation, relationModifier,
1130 structure, index, position, truncation. Note that the the latter ones
1131 override former ones for identical attributes.. The new scheme means that
1132 it is possible to override any existing attribute with a relationModifier.
1133 And also that it is possible to override everything for the index rule
1134 (except the ones listed in relationModifier). No order is perfect but this
1135 one, we believe, covers more real cases.. The "always" should have been
1136 called "default", since the attributes there can be overridden with all
1139 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1140 compilation phase, but also for yaz-config --cflags output. This allows
1141 us to have public headers with Libxml2 stuff in them . It should also,
1142 eventually, make Libxml2 checks redundant in packages using YAZ, such
1145 --- 2.1.22 2006/06/15
1147 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1148 stored in uri, message and details.. Previously diagnostics were stored
1149 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1150 compatibility.. but he's probably the only one affected, so.
1152 Added support for CCL, compiled on the client side, in ZOOM-C. This
1153 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1154 input; the resulting query objects can be used for for searching with
1155 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1157 YAZ' configure searches for OpenSSL by default.
1159 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1160 SL_CTX_use_certificate_file. See
1161 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1162 for more info. Thanks to Ko van der Sloot.
1164 --- 2.1.20 2006/06/02
1166 Bug #600: SRU GET, POST support for yaz-client. Introduced
1167 command 'sru' which selects method SOAP/GET/POST.
1169 Allow missingValueAction to be specified for the sortspec string -
1170 function yaz_sort_spec. By default, the missing value action is null.
1171 Use ! to specify "abort". Use = followed by stringvalue to specify default
1174 Ensured that Present-handler (if defined) is called in GFS before any call to
1175 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1176 searchRetrieve requests.
1178 Documentation for YAZ is now based on the Docbook XML/XSLT using
1179 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1180 is no longer depending on jade/openjade or docbook-to-man scripts.
1181 PDF is no longer part of the distribution - but can optionally be
1182 made using DSSSL/jadetex or FOP.
1184 Added retrieval handling support in Generic Frontend Server to support
1185 conversion between MARC/XML as well as XSLTtransforms. See
1186 etc/yazgfs.xml for an example.
1188 Added Authentication support to Generic Frontend Server in SRU
1189 mode. Authentication using HTTP Basic is supported, as is the use
1190 of 'x-username' and 'x-password' parameters in the request itself.
1192 Added support for a new character set MARC8s identical to MARC8 except
1193 that it converts combined characters to single Unicode characters in the
1194 Latin-1 range (when possible).
1196 --- 2.1.18 2006/04/24
1198 ASN.1 compiler 0.4: generates brief Doxygen file header for
1199 generated .h/.c files.
1201 Utility yaz_iconv now supports conversion to MARC-8.
1203 New facilities for the MARC module. The reading - and writing of
1204 content are separate methods for the yaz_marc_t handle. The following
1205 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1206 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1207 format). Write functions have prefix yaz_marc_write_.. The existing
1208 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1209 available. Removed support for OAI-MARC and simplexml (not the
1210 simplexml from PHP5).
1212 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1213 to be returned for this connection.
1215 --- 2.1.16 2006/03/31
1217 Allow multiple languages and charsets to be specified with
1218 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1219 negcharset iso-8859-1,utf-8
1221 Translation of proximity nodes from CQL into PQF now works.
1223 Moved to automake 1.8, 1.9.
1225 Added function yaz_log_set_handler which allows a log handler to be
1226 installed. This handler will be called for all log messages. Output
1227 to file is also produced; but that can be disabled by passing NULL
1228 fname to yaz_log_init_file.
1230 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1232 For SRW (including GFS), accept application/soap+xml as content-type
1235 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1236 produces NO stylesheet reference even if a default stylesheet is specified
1239 --- 2.1.14 2006/03/14
1241 Updated Windows package to include yazd.dll + yazd.lib for the
1242 Development component.
1244 If the environment variable YAZ_LOG is set, then it is used as a
1245 string indicating the default level of logging to use if not
1246 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1247 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1248 used as before. So, for example, to omit warnings from YAZ logging,
1249 export YAZ_LOG=-warn
1251 cql_transform() now map structure and other attributes before indexes,
1252 so that index-specific structures and other attributes can override
1253 defaults. So now a combination of mapping specifications such as:
1255 index.dc.date = 1=date-modified 4=5
1256 does the right thing.
1258 cql_transform() now also respects the "always" mapping specification,
1259 which establishes an initial set of attributes to be used for all
1260 terms except where overridden by more specific attributes associated
1261 with the index, relation or modifier.
1263 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1264 which mode to use; one of "post", "get" or "soap" (SRW, default).
1266 Fixes for yaz_iconv routines: changed trie-based character set conversions
1267 to use only non-negative values for bit fields due to Sun's C compiler not
1268 supporting negative values.
1270 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1271 sequences where not read correctly. Fix by Rustam Usmanov.
1273 Updated win/makefile to use options, settings which makes things
1274 compile with VS C 2005.
1276 --- 2.1.12 2006/02/01
1278 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1280 In ZOOM socket code, use select instead of poll on MacOSX.
1282 ZOOM-C now support client-side compilation of CQL into RPN that is
1283 sent to the server, enabling CQL to be used against all Z39.50
1284 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1285 ZOOM_query object, and submit it using ZOOM_connection_search().
1286 The CQL-to-RPN translation uses a configuration file, the name of
1287 which must be specified in the Connection's "cqlfile" option.
1289 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1290 function, which takes as its start-term parameter a ZOOM_query object
1291 (which may have had either CQL or RPN set into it).
1294 --- 2.1.10 2005/11/29
1296 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1297 GFS to support this as well. Backend handler, bend_srw_update, does the
1298 update work. Code contributed by Ko van der Sloot.
1300 Allow retrieval of Search Result-1 information in ZOOM by the use of
1301 options that are attached to a result set. ZOOM documentation updated
1304 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1305 UTF-8 conversion. Patch by Raj Patel.
1307 Added option -m to GFS to control formatting of timestamps in log file.
1309 Added 'exit' as synonym for 'quit' in yaz-client
1311 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1312 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1313 for the new members. Patch by Ko van der Sloot.
1315 Added support for SRU POST. It is supported for content-type
1316 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1318 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1319 Instead make the library libyaz.la multi-threaded. Threading as a whole
1320 can still be disabled by configure option --disable-threads. Previosly,
1321 with older GLIBCs there were problems with MT libs under Apache. This
1322 has now been fixed a long time ago.
1324 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1327 CQL module modified to be case insensitive for relations/indexes/operations.
1329 Fixed bug in CQL transform code: incorrect value relationModifieder
1332 Added 'show all' command for yaz-client which retrieves all results
1335 Added new yaz-client, xmles, which takes a (private) OID and
1336 a document to be sent as an extended service request.
1338 Describe new yaz-client commands wait_response and set_auto_wait.
1340 Increase TCP/IP listener backlog from 3 (which I am guessing was
1341 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1342 that the socket will queue as many incoming connections as it's able
1343 to handle ongoing connections. In other words, it will never now
1344 refuse a connection that it would be able to handle merely because
1345 it's not got around to accepting() enough of the pending connections
1346 yet. This is the behaviour anyway under Linux, where the listen()
1347 argument is ignored; but not under BSD and on systems such as
1348 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1349 YAZ-based servers should now be uniform across operating systems in
1352 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1353 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1354 This allows yaz-marcdump to read large MARC batches (>2 GB).
1356 Modified all YAZ source files - except the source which is auto-generated
1357 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1360 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1361 corresponding to the existing *_setl() function. These allow option
1362 values containing arbitrary valuues.
1364 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1365 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1366 except that it returns an indicator of whether or not the sort
1367 criterion was accepted (0 for OK, -1 for invalid).
1369 --- 2.1.8 2005/06/07
1371 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1372 MARC output rather than returning "new" buffer.
1374 yaz-client warns about unknown init options.
1376 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1378 --- 2.1.6 2005/05/24
1380 Added support for SRW sort in Generic Frontend Server. Patch
1381 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1382 sortKeys - or NULL if none is provided.
1384 Fixed bug #307: It was impossible to specify indefinite/no timeout
1385 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1388 Added support for multiple languages and charsets to be specified in
1389 ZOOM. Each charset/language is separated by a blank. If negotiation is
1390 in effect in init-response, Option
1391 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1392 Code based on patch by Vasiliy Osadchuk.
1394 Fixed bug #306: infinite recursion that occurred when calling
1395 yaz_log_level_init as the first call (before other log level or
1398 Fixed bug in scan handling in front end server: if preferred-Position-In-
1399 Response was non-present, a NULL pointer referece was performed.
1401 --- 2.1.4 2005/04/26
1403 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1404 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1405 now defined for all those error codes. So instead of putting 109 in
1406 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1407 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1409 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1412 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1414 Program yaz-client now exits and produces an error message if multiple
1415 Z39.50 servers are specified on the command line (none or one allowed
1418 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1421 --- 2.1.2 2005/03/16
1423 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1425 Fixed bug #272: Preserve spacing for CCL terms.
1427 --- 2.1.0 2005/03/14
1429 Added support for virtual hosts and multiple backend servers for
1430 the YAZ frontend server. The configution is XML based and
1431 support specificition of CQL to RPN mappings and explain information.
1432 See section "Virtual Hosts" in the YAZ manual.
1434 Extended OPAC display utility. OPAC display utility renders
1435 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1436 to supplement yaz_marc_decode_wrbuf.
1438 Fixed a bug in MARC decoder that could caused it to crash for some
1439 invalid MARC records. More diagnostics and warnings where added in
1440 XML output (warnings, etc are stored in comments).
1442 --- 2.0.34 2005/02/08
1444 Fixes for UNIX domain sockets. Bug #261.
1446 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1448 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1449 Added yaz_marc_subfield_str which defines subfield lead string which is
1450 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1451 yaz_marc_endline_str which defines end of fields string used in
1452 YAZ_MARC_LINE format. Default string is newline.
1454 Experimental support for MarcXChange. This format can be produced
1455 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1456 http://www.bs.dk/standards/MarcXchange.xsd
1458 Added yaz-client commands scansize that sets maximum number of
1459 entries to be returned by scan.
1461 --- 2.0.32 2005/01/11
1463 Added support for SRW scan in yaz-client and Generic Frontend Server.
1465 * Added whereInList member to SRW Scan Term.
1467 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1469 Fixed NMEM system to return aligned blocks on the smallest boundaries
1470 that are suitably aligned for all possible types on the particular
1471 architecture YAZ is being built for.
1473 --- 2.0.30 2005/01/04
1475 Fixed numerious warnings that was issued with newer versions of GCC.
1477 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1478 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1481 Make YAZ Generic Frontend Server slightly faster.
1483 Enhance (and reduce) logging for Generic Frontend Server.
1485 Revert YAZ log system so that it flushes every write operation
1486 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1488 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1489 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1490 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1491 will effectively disable old definitions.
1493 --- 2.0.28 2004/11/09
1495 Added yaz_log_time_format which specifies log format using
1498 Added yaz_log_module_level which returns mask for a module. Value
1499 is non-zero mask a if module is enabled; zero if disabled.
1501 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1502 in include/yaz/cql.h.
1504 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1506 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1508 Fixed bug #172: RPM builds does not enable SSL.
1510 Doxyfile.in part of dist. Doxyfile generated by configure.
1512 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1513 are given and the corresponding component does not exist.
1515 Extend CCL documentation in YAZ reference. Describe r=r.
1517 --- 2.0.26 2004/10/01
1519 Fixed MARC->MARCXML conversion to properly deal with
1520 fields, subfields, indicators having non-ASCII characters.
1522 Fixed MARC->MARCXML conversion so that ASCII control characters
1523 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1526 Added YAZ GFS support for conversion from Z39.50 surrogate
1527 diagnostics to SRW surrogate diagnostics.
1529 Bug fix: YAZ GFS did not return schema in explainResponse.
1531 --- 2.0.25 2004/09/30
1533 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1534 now converts recordSchema to elementSetName as well as schema URI.
1536 Fixed bug in COMSTACK that prevented HTTP request packages from being
1539 --- 2.0.24 2004/09/29
1541 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1542 does not require white-space before and after the dash in a range, e.g.
1543 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1546 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1547 due to new GCC removing "redundant" code.
1549 Added yaz-client commands scanpos and scanstep that sets preferred
1550 position and step-size for scan.
1552 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1554 Added CCL utility ccl_qual_buf which parses one or more CCL
1555 spec lines in a buffer.
1557 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1558 of name and value - ignoring empty lines and comments.
1560 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1562 Added odr_get_element_path which returns current element path for an
1563 ODR handle. This utility is useful in error handling or user-defined
1566 Added ODR_PRINT utility odr_set_stream which is is a more generic
1567 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1568 to a write function and pointer to close function. The close function - if
1569 non-NULL - will be called during odr_destroy.
1571 Fixed bug in CCL parser where truncation char was not removed from
1572 right side when truncation=both was in effect.
1574 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1577 --- 2.0.23 2004/08/11
1579 Fix buffer overrun in CQL parser when dealing with proximity (%).
1581 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1582 to UTF-8/UCS conversion is now only based on codetables.xml.
1584 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1586 --- 2.0.22 2004/08/06
1588 Add support for more "commit changes" in ZOOM (uses Extended Services).
1590 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1593 Yet another small fix for configure of SSL.
1595 --- 2.0.21 2004/05/14
1597 Fix SSL libs for configure when --with-openssl=DIR is given.
1599 --- 2.0.20 2004/05/10
1601 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1603 SSL comstack now uses yaz.pem certificate file on server side
1604 by default. Certificate filename can be configured by calling
1605 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1607 Fix bug regarding multiple calls to ZOOM_connection_connect.
1609 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1611 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1612 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1614 ZOOM now allows inspection of X509 peer certificate for verification.
1615 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1617 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1618 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1619 as "modular" but it simplifies things.
1621 Added cs_get_peer_certificate to that returns peer X509 PEM.
1623 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1624 NULL if SSL is unavailable.
1626 Documentation about MARC decoding tools.
1628 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1630 --- 2.0.19 2004/03/30
1632 Rename CHANGELOG to NEWS to follow GNU style packing.
1634 Fix bug with missing initialization of member in init_diagnostics.
1635 This bug affects threaded version of GFS server.
1637 --- 2.0.18 2004/03/20
1639 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1642 Ensure zlib.dll is packed with Windows install.
1644 --- 2.0.17 2004/03/17
1646 Fix encoding of xsd:string to use text instead of CDATA.
1648 Fix endless loop in CQL parser with unbalanced ".
1650 Use a more compact way to store MARC-8 conversion tables.
1652 --- 2.0.16 2004/03/16 Debian only
1654 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1657 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1662 --- 2.0.15 2004/03/01
1664 Another fix for decoding of XML packed records.
1666 --- 2.0.14 2004/02/25
1668 Fixes for Chunked encoding. White space not ignored after length spec.
1670 Update NS and use default NS for SRW diagnostic elements.
1672 --- 2.0.13 2004/02/23
1674 Implement ZOOM_resultset_cache_reset which resets record cache.
1676 Implement ZOOM_resultset_sort which sorts a result set.
1678 Implement chunked HTTP transfer.
1680 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1682 --- 2.0.12 2004/02/16
1684 Added member 'schema' to bend_explain_rr structure so that backend
1685 can specify explain record identifier. Defaults to Zeerex 2.0.
1687 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1689 --- 2.0.11 2004/02/16
1691 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1694 Added init command for yaz-client which sends "extra" init request.
1696 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1697 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1699 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1701 Make ZOOM error code for "invalid query".
1703 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1705 --- 2.0.10 2004/02/05
1707 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1710 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1712 Added option -p <file> to make Generic Frontend Server to write PID file.
1714 Added option -D to put Generic Frontend Server in background on its own.
1716 Make ZOOM C recognize option "password". If unset, "pass" is used
1717 (for backwards compatibility).
1719 Fixed a bug in Generic Frontend Server that could make it crash if a
1720 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1723 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1724 Must be issued before open, in order to be in effect.
1726 --- 2.0.9-6 2004/01/12 Debian/Windows
1728 Make the SRU server more picky WRT unknown params, etc.
1730 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1732 New YAZ client command, options, that sets Z39.50 options.
1734 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1735 options from a string of tokens (one token for each option bit).
1737 Update SRW diagnostic code messages.
1739 --- 2.0.9-5 2004/01/07 Debian/Windows
1741 Handle user defined stylesheet for SRW/SRU.
1743 --- 2.0.9-4 2004/01/06 Debian/Windows
1745 Fix bug in decoding of Content-Length.
1747 --- 2.0.9-3 2004/01/06 Debian/Windows
1749 Fix a bug with decoding of XML packed records.
1751 --- 2.0.9-2 2004/01/05 Debian only
1753 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1755 Fix bug in SRW/SRU diagnostics decoding.
1757 --- 2.0.9 2004/01/05
1759 Fixed bug in Generic Frontend Server which could drop records exceeding
1760 preferred message size. Reported and fixed by Irina Dijour.
1762 Fixed calculation of package size for structured records in Generic
1763 Frontend Server. Reported and fixed by Irina Dijour.
1765 Fixed namespace for SRW/SRU diagnostics.
1767 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1769 --- 2.0.8 2003/12/22
1771 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1772 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1775 CQL changes to reflect recent changes to the specification:
1776 * Documentation talks about context sets instead of index sets.
1777 * Documentation talks about indexes instead of qualifiers.
1778 * The CQL-to-PQF transformer's configuration file now uses
1779 "index.set.name = <attributes>" instead of the old form
1780 "qualifier.set.name = <attributes>". (Both forms are still
1781 understood but the latter is deprecated.)
1782 * CQL terms with no explicit index specified are now interpreted as
1783 cql.serverChoice instead of srw.serverChoice (which of course
1784 behaves exactly the same.)
1786 --- 2.0.7 2003/12/16
1788 MARC conversion can now generate ISO2709 output in another
1789 character set. yaz-marcdump uses this facility if you invoke it
1792 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1793 functions from there can be used from C++.
1795 --- 2.0.6 2003/12/04
1797 Frontend server now transfers memory from decoded packages to stream
1800 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1801 references to show up.
1803 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1804 the ZOOM Abstract API. The older names for the same options are still
1805 also supported for the benefit of old applications.
1807 ZOOM-C supports "implementationId" and "implementationVersion" options
1808 to go along with "implementationName". These allow the user code to
1809 specify identification strings to be sent to servers.
1810 Add OID for the new ExtLite attribute set.
1812 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1813 as requested/supplid by Ere Maijala <ere@atp.fi>
1815 For generic frontend server, reverse the order of
1816 "toolkit-supplied / application-supplied" strings sent as implementationId,
1817 Name and Version. Also, remove the spaces around the slash. This brings
1818 the GFS in line with the behaviour of ZOOM-C on the client side.
1820 Add function ZOOM_scanset_display_term.
1822 yaz-client shows scan displayTerm if present.
1824 Utility yaz-iconv is now installed by default along with the man page
1827 Extend configure check for OpenSSL to use pkg-config where available (such
1830 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1831 server to specify uid/gid/mask for socket using the format
1832 unix:[user=uid,][group=gid,][umask=mask,]file=path
1833 If file= is omitted the existing format is assumed, e.g.
1835 in which case the mask is 0666 (rw for everybody).
1837 Major restructure of YAZ source. All source in libyaz is in src directory.
1838 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1839 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1841 Added man page for utility yaz-marcdump (used to be called marcdump).
1842 yaz-marcdump is installed by 'make install'.
1844 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1845 of incoming package failed.
1847 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1849 Change prototype of odr_perror: add const to message string.
1851 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1853 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1854 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1855 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1856 DNS lookup. There should not be any compatibility problems with this
1857 assuming that blocking=1 or 0 is used.
1859 Fix bad reference in UNIX comstack in function cs_addrstr.
1861 Fix for compilation on AIX.
1863 The generic front-end server (server/seshigh.c) now supports returning
1864 Init diagnostics to the client in User-information-field, in
1865 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1868 --- 2.0.4 2003/09/04
1870 Allow any CQL relation (not just all,any,exact,scr).
1872 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1873 that features the same UI.
1875 Implemented command update0 in YAZ client which is equivalent to
1876 update but uses old of Ext Update ASN.1.
1878 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1879 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1880 Previously no OID was used for this info.
1882 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1883 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1884 returns 'malformed search term' otherwise.
1886 SortResponse member resultCount now set to NULL in sort handler of
1889 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1892 Add three new utility functions for translating OIDs between various
1893 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1894 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1895 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1896 char *oid_to_dotstring(const int *oid, char *oidbuf);
1897 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1899 Reverted modifications for ES Update definition for z_IU0Update
1900 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1901 is back to YAZ 2.0.2.
1903 String value attributes for CCL parser.
1905 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1906 which their FirstSearch server returns in Init responses, sometimes
1907 carrying useful diagnostic information when Init fails. This has the
1908 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1909 "z39.50/oclcui.asn", where its definition is somewhat different from
1910 what OCLC document on their web-site, as required to interoperate with
1913 Support for anonymous authentication in yaz-client. Use the command
1916 * Fix the OID of the Index Data-local "admin" Extended Service from
1917 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1918 the 1000, which indicates a locally-defined OID, was a mistake.
1920 --- 2.0.3 2003/06/20
1922 Fix CCL directive @case handling so that it affects string match for
1923 both CCL keywords and qualifiers.
1925 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1926 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1927 Decoder has been updated with ASN.1 changes as listed in
1928 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1929 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1930 z_IUUpdate, remains unchanged.
1932 ZOOM_record_get may now return a record in a specific character set.
1933 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1934 "from" is the character set of record as returned by target. "to" is
1935 the character set to be returned. If omitted, "to" is UTF-8.
1937 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1939 New ODR utility, odr_getelement, which returns name of element for
1940 which encoding/decoding failed.
1942 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1943 in cases where a required element was omitted.
1945 Bug fix: some MARC8 sequences were not converted.
1947 New ZOOM option "step" which specifies number of records to be
1948 retrieved in one chunk. Used in conjunction with "start" and "count".
1950 SRW support for yaz-client. Use scheme http: to use it, e.g.
1953 yaz-client no longer does (un)intelligent character set conversions
1954 by default. Can be enabled with charset and marc_charset commands.
1956 xmalloc trace fix for 64-bit systems such as DEC alpha.
1958 Solaris 2.6 compile fix.
1960 New function, cql_strerror() translates SRW error codes, as returned
1961 by cql_transform_error(), into human-readable English strings. Used
1962 in yaz-client diagnostics when appropriate.
1964 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1965 converts it into a type-1 query which is sent to the server. This
1966 makes CQL available for use with all Z-servers, as opposed to the tiny
1967 minority that can handle CQL queries themselves.
1969 --- 2.0.2 2003/04/28
1971 New Debian package layout similar to the Redhat Package layout.
1973 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1974 and search result respectively.
1976 --- 2.0.1 2003/04/25
1978 Redhat package is now several packages: libyaz (runtime libraries),
1979 libyaz-devel (development and documentation, and yaz (utility programs).
1980 Package spec file by Morten Bogeskov.
1982 New member 'schema' in struct bend_fetch_rr which the name of requested
1983 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1984 handler MAY set this to reflect the schema of the returned record.
1986 New member 'display_term' in struct scan_entry. GFS now sets member entries
1987 and allocates scan entries to be filled by user scan handler. In previous
1988 version, entries member was allocated by the scan handler. That still works,
1989 but the GFS will ignore member display_term - assuming it was NOT set by
1990 the handler. The fact that the GFS now allocates the entries both allows
1991 for new members and makes a scan handler easier to write.
1993 Fix CQL lex buffer overflow.
1995 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1996 SRU default recordPacking is string.
1998 SRU protocol support for frontend server.
2000 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2002 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2004 Added scan for the ZOOM shell (zoomsh).
2008 * String Identifers for Schemas (Amendment 5).
2009 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2010 Old definition for schema
2011 Odr_oid *schema; /* OPT */
2016 Z_InternationalString *uri;
2017 #define Z_Schema_oid 1
2018 #define Z_Schema_uri 2
2021 * resultCount parameter to Sort Response (Amendment 1).
2022 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2024 Support for SRW 1.0 over HTTP. This is an optional feature and
2025 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2028 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2029 on the same port. SRW SearchRetrieveRequests are mapped
2030 to bend_init,bend_search,bend_fetch,bend_close.
2032 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2034 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2035 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2037 ZOOM connections are SRW based if schem http is used for hostname
2038 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2039 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2041 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2042 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2043 distance=n, order=true/false, relation=le, prox unit=word. If
2044 n is omitted, distance 1 is used.
2046 Fixed problem with C compiler include path in wrong order.
2048 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2049 on Solaris. Patch from Ko van der Sloot.
2051 New MARC decode API. All new functions operate on a yaz_marc_t
2052 handle. The most important new functions are: yaz_marc_create,
2053 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2054 decode and destroy respectively. Decoder can produce formats
2055 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2056 include/yaz/marcdisp.h.
2058 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2059 to UTF-8, UCS-32, wchar_t or Latin-1.
2061 * Prototypes for yaz_iconv_-functions moved to separate header
2062 include/yaz/yaz-iconv.h.
2064 Make a few private functions 'static' in unix.c. This prevents
2065 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2067 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2068 are set when Init Response is received.
2070 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2071 but returns diagnostic set as well.
2073 New function yaz_strerror which is a portable wrapper for
2074 strerror/strerror_r/GetLastMessage.
2076 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2077 is returned for MARC. If type is "oai", then OAI MARC is returned.
2079 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2082 --- 1.9.2 2002/11/26
2084 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2086 Fix bad race conditions on SIGTERM and terminate gracefully in
2089 Move retrieval (data1) module to Zebra since nobody seems to be
2092 Add GRS-1 render for ZOOM using same format as yaz-client.
2094 --- 1.9.1 2002/10/05
2096 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2098 Fix broken ESpec handling in data1 module.
2100 SGML reader parses comments and makes them part of the data1 tree.
2102 Added several type casts so that YAZ compiles as C++ code.
2104 ZOOM didn't handle PDU encoding failures properly.
2106 Added more Bib-1 diagnostics (approved extensions).
2108 GNU configure: better check for iconv.
2110 More portable use of accept, getpeername. Check for socklen_t. Use
2111 int/size_t if socklen_t is not defined.
2115 PQF parser rejects bad queries - including those with extra
2116 characters in them. PQF parser used to silently ignore that.
2117 Cleaner API for PQF added, which allows you to get detailed
2118 error information for bad queries (see yaz/pquery.h).
2120 Fixed bug in ZOOM_record_get for type "database".
2122 Implemented mini iconv library supporting conversions between
2123 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2125 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2127 --- 1.8.9 2002/08/20
2129 Fixed ZOOM C record cache so that preferredRecordSyntax and
2130 elementSetName is used to check for already fetched records.
2132 --- 1.8.8 2002/08/02
2134 Added three members in bend_initrequest structure to facilitate
2135 character set negotiation.
2137 Fixed a bug in frontend server that could cause indefinite
2138 loops under rare conditions.
2140 Revised character set utilities (charneg.h) so that encoding
2141 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2143 For PQF, directive @term <type> sets term type for Scan/Search.
2144 Here <type> is general, string, numeric, null. The term type
2145 is inherited - just like @attr.
2147 New call odr_set_charset that sets character set conversion for
2148 international-strings on a ODR stream. Prototype is:
2149 int odr_set_charset(ODR o, const char *to, const char *from);
2150 The InternationalString is still represented as C string in YAZ
2151 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2152 won't). On the protocol level, you can use any encoding.
2154 Support for UNIX sockets in ZOOM.
2156 Solaris recv sometimes returns errno == ENOENT. It is treated as
2157 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2159 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2160 both client and server. Code by Morten Bogeskov.
2162 --- 1.8.7 2002/05/22
2164 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2165 that they can be used directly from Visual Basic. You must recompile
2166 your windows APP if you're using ZOOM.
2168 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2169 Commands "lang" and "charset" sets language and character set respectively.
2170 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2171 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2173 Attributes from multiple CCL fields may be OR'ed rather than merged
2174 using directive "@field or". Fields are still merged by default -
2175 equivalent to "@field merge".
2177 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2180 Fixed bug in zget for parameter ExtendedServicesResponse.
2184 --- 1.8.6 2002/03/25
2186 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2188 Client displays USR.1:SearchResult-1 (hits per term).
2190 Additional Search Info for search in Generic Frontend Server.
2192 Fixed CCL parsing of "field=s".
2194 WIN32 installer - using the excellent NSIS software from nullsoft.
2196 Fixed CCL parsing of "field = - <number>".
2198 Added function yaz_marc_decode that decodes MARC for line mode
2199 display or XML (similar to that used by JZKit).
2201 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2202 Z39.50. But ISO/ILL was, however.
2204 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2205 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2207 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2208 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2210 --- 1.8.5 2002/02/03
2212 New YAZ client features: Command completion and new commands:
2213 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2214 Code provided by Jacob Poulsen.
2216 New call oid_trav, that visits all registered OIDs via callback.
2218 Function ZOOM_record_get now returns const char pointer rather than
2219 void pointer. It saves a lot of type casts.
2221 For YAZ client, command "auth" now allows you to set authentication
2222 in IdPass style. It is enabled when three tokens are given - order
2223 is user, group and password.
2225 Fix memory leaks in MARC record handling for ZOOM.
2227 New option for YAZ client, -k <kilobytes> that sets
2228 maximum record size. Similar to -k option for generic frontend
2229 server and yaz-ztest.
2231 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2233 Prefix query parser reports "fail" when bad attribute set is given.
2235 Fix in MARC decoder. Proximity logging. Fix for attribute set
2236 in scan handler for server. Patches by Shigeru Ishida.
2238 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2241 Configure option --with-openssl=<dir> now works when a directory is
2242 specified. Patch provided by Morten Bogeskov.
2244 New option for YAZ client, -u <auth>, that sets authentication.
2246 ZOOM fix: error information was sometimes "missing", since error
2247 was cleared/reset too when it shouldn't.
2249 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2251 --- 1.8.4 2002/01/04
2253 Scan for ZOOM API. New object ZOOM_scanset. New functions
2254 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2255 ZOOM_scanset_destroy.
2257 New ZOOM function, ZOOM_connection_last_event, that returns type
2258 of last event (such as "receive data", "send data", "apdu received",
2261 New ZOOM option, schema, that specifies schema for retrieval.
2263 New CCL feature. Qualifiers can be aliases for one or more
2264 other qualifiers (if more than one is given, OR is used).
2266 ZOOM uses named result sets if target supports it.
2268 Two new YAZ client commands: . (dot, which sources a script of YAZ
2269 client commands), and ! (to execute shell command.). Implemented
2272 Working on Debian packages.
2274 --- 1.8.3 2001/11/19
2276 YAZ client enables named result sets only if target supports it.
2278 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2280 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2281 with key="host" to get same result.
2283 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2284 Function Z3950_resultset_record(s) returns references to records
2285 "owned" by resultset. To become owner use Z3950_record_clone.
2287 Function z_ext_record handles Extended Services. Thanks to
2290 --- 1.8.2 2001/11/12
2292 CCL Parser fix: ignore token comma when dealing with and-lists.
2294 Documentation updates for COMSTACK.
2296 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2297 Changed prototype Z3950_records. For some functions, int parameters
2298 were changed to size_t.
2300 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2303 New MARC decode/display function, marc_display_exl, which properly rejects
2304 non-ISO2709 records. YAZ client uses it.
2306 --- 1.8.1 2001/10/29
2308 Fix bug: local attribute set wasn't set correctly in PQF strings.
2312 * Old Z39.50 codecs no longer supported.
2314 Added ZOOM C binding. See http://zoom.z3950.org/
2316 Renamed states for COMSTACKs to avoid confusion with events.
2318 Implemented cs_look and proper cs_rcvconnect.
2320 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2322 Configure detects POSIX threads on OpenBSD.
2324 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2325 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2327 When error is returned from present handler, non-surrogate diagnostic
2328 is returned in present response (and fetch handler is no longer called).
2330 * Minor adjustments to pquery parser (PQF). Token characters may be
2331 escaped by using backslash (C-style).
2333 PQF parser allows string attribute values to be specified. For @attr,
2334 non-numeric characters after the equal-sign are treated as strings
2335 (e.g. @attr 9=title).
2337 CCL trunction character may be defined (@truncation in file)
2339 * function zget_ExtendedServicesRequest sets waitAction to
2340 waitIfPossible (was wait).
2342 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2345 CCL operator names may be set in field definition files (CCL_bibset).
2346 See ccl/bib1 for an example.
2348 Fixes in ASN.1 compiler for C++ compatibility.
2350 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2351 and "op_or" to avoid conflict with C++.
2353 Fixed problem with GNU readline detection on Redhat 7.0.
2355 Added step-size for Scan backend handler.
2357 Fixed bug that made the frontend server crash when no attribute
2358 set was specified for scan.
2360 Front-end server automatically switches to original working directory
2361 when installed as an NT service. Previously -w had to be specified to
2364 Added extended attributes for retrieval module (data1), so that data1
2365 records carry d1_readXML/SGML attributes. d1_read also supports
2366 null-data rules ( <tag/>)
2368 On UNIX when POSIX threads are available, a separate library libyazthread
2369 is created. Programmers should link with that library and the yaz library
2370 when using threads. The reason for the split was that some applications
2371 on Linux, such as Apache, doesn't work well when using shared objects that
2374 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2375 (or any frontend server) in SSL mode by specifying ssl: followed by
2376 address. Only tested on UNIX.
2378 Added feature for CCL module. Virtual structure s=al or s=ol generates
2379 and-list and or-list respectively instead of phrase search.
2383 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2384 log_mask_str. This was done to avoid name conflicts with other libraries
2385 (such as other PHP extensions).
2387 Added raw OID member for preferred record syntax (request_format_raw)
2388 and returned record syntax (output_format_raw) for backend fetch method.
2390 Config file yaz-config now accepts options so that it returns specific
2391 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2393 Shared library support for UNIX using GNU libtool.
2395 * Modified backend interface. Request/Response struct's replaced by
2396 one read/write C struct. For example bend_fetchrequest and
2397 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2398 Every handler - even search has to be registered in bend_init
2399 handler. This means that the YAZ library no longer refers to
2400 external functions and it makes it possible to make the whole
2401 thing a single DLL/SO.
2403 Added Segment handler for backend server.
2405 Added Zmbol/Zebra administrative functions to YAZ client.
2407 Threaded frontend server on UNIX (when POSIX Threads are available).
2408 Starting the server with option -T enables multi-threading.
2412 Added configure option --enable-comp/disable-comp to control use
2413 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2414 located in sub directory asn.
2416 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2417 in ${exec_prefix}/bin along with the other programs yaz-client and
2420 GNU automake used to maintain makefiles.
2422 Added several OID's.
2424 Changed retrieval module so that we can load records with no abstract
2425 syntax defined. Tagpaths in these records are fully composed of string
2428 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2432 On UNIX, the generated makefile now supports a proper 'make install'.
2433 The prefix can be set via GNU configure to set the install location
2434 (default is /usr/local).
2436 * YAZ programs client and ztest were renamed to yaz-client and
2437 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2438 locations, such as /usr/bin,/usr/local/bin,etc.
2440 * YAZ Header files were moved from include to include/yaz. YAZ Header
2441 files are referred to as include <yaz/log.h> rather than <log.h>.
2442 The YAZ include path (-I ..) is therefore the same as before. Programmers
2443 should update their #include statements or use -Ipath/include/yaz
2444 instead. The main motivation for doing this change is that YAZ header files
2445 can be installed in "standard" locations /usr/include,/usr/local/include
2446 without introducing conflicts, since ALL YAZ header files are stored
2447 in subdirectory yaz (under /usr/include for example).
2449 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2450 rather than project/workspace files. We switched because project files
2451 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2454 Changed name of logging function, logf, to yaz_log, to prevent name
2455 clash with some math-log functions. The YAZ header log.h defines logf
2456 to yaz_log (#define) so there should be no incompatibilities by this
2459 Added bend_start/bend_stop handlers for server. These handler are
2460 called on start/stop of server. For windows they are called whenever
2461 a service is started/stopped.
2463 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2464 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2465 in util/yc.tcl. The auto-generated C code structures are, in a few
2466 cases, incompatible with the old decoders. There are differences in the
2467 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2468 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2469 The preprocessor variable ASN_COMPILED is defined when the compiled
2470 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2471 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2472 wish to use the old encoders/decoders you can specify --disable-yc
2475 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2476 version so that it supports both new - and old version of DB Update
2478 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2479 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2480 change. The name parameter can be set to 0 in which no name is specified
2481 for the construction. The macros odr_implicit and odr_explicit sets name
2482 parameter to zero for the construction involved. New macros
2483 odr_implicit_tag and odr_explicit_tag are similar to the others,
2484 except that a name parameter is added. For programmers' that don't use
2485 ODR they probably only need to change the call to z_APDU and z_External.
2487 Added access control facility by interfacing the TCP wrapper library.
2488 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2489 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2490 name of the daemon and enables the access control as specified in
2491 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2493 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2494 den Dool <H.M.vdnDool@kub.nl>.
2496 Added reference ID parameter to most functions in server API - refer
2497 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2499 Changed name of ccl library to libccl.a (was ccl.a).
2501 Fixed bug in decoder for Explain (Category TargetInfo).
2503 Added support for GNU readline in client. Thanks to Jacob Poulsen
2504 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2506 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2507 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2508 IMPLEMENTATION! This change was made to the development version before
2509 the ZIG decided to retract the amendment. If any users MUST be
2510 compatible with the original Update definition, PLEASE CONTACT US, and
2511 we will include a separate definition corresponding to the old Update
2512 ES. Note that because of the change to the ASN.1 of the
2513 TaskPackageRecordStructure we cannot define a single structure that
2514 will support both versions.
2516 * Added const modifier to buffer parameter for some ODR/BER encoding
2517 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2518 completeWAIS, odr_dumpBER.
2520 Fixed bug in client.c which caused a crash when a scanResponse didn't
2521 contain positionOfTerm.
2523 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2524 * will cause an error in a client if a non-YAZ target sends both a
2525 * list of Scan entries and non-surrogate diagnostics.
2527 Retrieval module enhancements. Tag sets may be typed in the reference
2528 to it. From the .abs-file the "tagset" directive takes a third optional
2529 integer type for the tag set referenced. From a .tag-file the "include"
2530 directive takes a third optional type as well. The old "type" directive
2531 in the tag set itself is still recognized but acts as the default type
2534 Backend interface change. Individual Scan terms returned from bend_scan
2535 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2536 in include/backend.h.
2538 Retrieval module enhancements. Multiple tag sets and attribute sets may
2539 be specified in abstract syntax specs. Revised the error/warning for
2540 logging messages reported by the retrieval module when reading the
2543 Object Identifier system (oid_..) changed. The API is backwards
2544 compatible but the oid-routines now allocates new OID's when needed.
2545 Raw OID's may be specified in oid_getvalbyname.
2547 YAZ now uses GNU configure to generate Makefile(s).
2549 * Minor changes in some of the member names of DeleteResultSetRequest and
2550 DeleteResultSetResponse. See include/proto.h.
2552 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2553 and added member 'languages' in TargetInfo (which was missing).
2555 Changed the way attribute sets are handled in the retrieval
2556 module. These are now cached, just like the abstract syntaxes
2559 Changed YAZ so that it links with compiled ASN.1.
2561 Added Explain-schema definitions and mapping routines. The following
2562 Explain categories have been implemented: AttributeDetails,
2563 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2565 Fixed minor bug in Windows version of Server Library.
2567 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2569 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2571 Added EXTERNAL: UNIverse Resource Report (non-standard).
2573 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2574 ENUMERATED and SET OF.
2576 * Added 'const' to some of the char pointer arguments for the
2577 functions, data1_read_node, data1_getelementbytagname,
2578 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2581 Fixed bug in data1_insert_taggeddata - the last_child member of
2582 parent wasn't initialised.
2584 * Changed data1_read_record and data1_read_node so that the supplied
2585 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2586 doesn't refer to any parts of the "SGML"-buffer.
2588 Fixed bug in server library (Windows version of statserv_remove).
2590 * Changed code so that it compiles as C++. The type definition
2591 of Odr_fun which is a member of Odr_arm was changed. The result is,
2592 that an explicit typecast is needed for the fun pointer when
2593 using Odr_arm - as in:
2594 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2596 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2598 Implemented the new structured date and time definition as approved
2599 by the ZIG. Added schemaId element to the specificTag in Espec-1
2600 (also approved at the last ZIG). Thanks to RVDM.
2602 Added some Object identifiers (RVDM).
2604 Changed the Update Extended Service (RVDM).
2606 Added command "refid" to client which specifies referenceId for
2607 the following requests.
2609 Implemented extended service handling for server. See ztest.c
2610 for an example as well as backend.h. New handlers are registerd
2611 in the Init handler.
2613 * Changed interface for sort in server.
2615 Added new members to statserv_options_block. It allows a server
2616 to read options from another source than just the command line. Thanks
2617 to Charles Woodfield.
2619 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2620 renamed to zboolean. Some C++ compilers complained about the name.
2622 Minor changes to gils.abs. Added index 's' (sort) on title
2623 and date/time-last-modified.
2625 --- 1.4pl2 1998/1/30
2627 Fixed bug in server library regarding inetd mode (-i). This bug
2628 was introduced by release 1.4.
2630 --- 1.4pl1 1998/1/29
2632 Added sort facility in client and backend server interface.
2634 Fixed problem with dependencies in Makefile(s).
2636 Fixed bugs for encoders/decoders of extended services and
2639 Implemented sub-tree feature for schemas. Sub-trees are
2640 referenced in *.abs-files. See explain.abs for an example
2641 of the use of this feature.
2643 Modified bib1.att; local attributes for ANY didn't include
2644 ANY itself (only affects use of the retrieval module).
2646 Fixed bug in plain SGML reader in function data1_read_node:
2647 tags with prefix "var" was incorrectly interpreted as variants.
2649 Added feature "sub-schemas" to enable references to - and definitions
2650 of - group of elements.
2652 * Removed member parent from type data1_element (in data1.h).
2654 Implemented function odr_nullval() that returns the value of
2657 * Removed member num_children from data1_node (in data1.h).
2659 Made NT service interface part of the server library. The
2660 function statserv_main uses the NT service when required and
2661 calls the statserv_start / statserv_close routines.
2663 Routine zget_SearchRequest and zget_PresentRequest fills
2664 resultSetName/Id member with "default" instead of "Default".
2666 Fixed memory leak in server. Request queue member wasn't freed.
2668 Fixed nmem_exit so that memory is freed.
2672 Revised the CCL parser utility to be thread safe.
2674 Added function, oid_ent_to_oid, to replace the function
2675 oid_getoidbyent, which is not thread safe.
2677 * Added nmem_init and nmem_exit to initialize and release
2678 NMEM resources. Function nmem_init should be called once in the
2679 initial thread before NMEM/ODR is used. statserv.c and client.c
2680 have been changed accordingly. The change was necessary to make
2681 NMEM thread safe. The NMEM memory pool is shared amongst threads
2682 in a process. Unix-based applications will still work fine without
2685 Added NT Services interface for the the Z39.50 (statserv) Server.
2686 Refer to the ztest.c source on the usage.
2688 Windows 95/NT port using MSVC5.0. Project files are included in the
2691 * Defined new 'global' handle for the retrieval (data1) system. The
2692 new handled, data1_handle, describes the state of the data1 system.
2693 This handle is passed as first argument to virtually all
2694 data1 related routines. The functions data1_create and data1_destroy
2695 creates and destroys a data1 handle respectively.
2697 Added ODR encode stream member to all backend request structures
2698 init, search, scan etc. This stream should be used to allocate all
2699 memory used for the response when thread safe operation is needed.
2701 Changed the comstack utility, cs_addstr, to be thread safe. The
2702 returned hostname string returned by the function is now part the
2705 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2706 function. The cs_straddr takes a COMSTACK handle as argument, so this
2707 function must be used after cs_create and before bind/connect.
2708 This function is thread safe.
2710 Moved test server to 'ztest' directory - generic server code still
2711 in 'server' directory.
2713 Made prefix query (pquery.c) utility thread safe.
2715 Added new function modifier YAZ_EXPORT to 'export' public DLL
2716 functions when using windows (see include/yconfig.h).
2718 Added definitions to the OID database (util/oid.c) (RVDM).
2720 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2722 Added call to ccl_rpn_delete in client program.
2724 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2725 release of RPN structure.
2727 Added support for C++, headers uses extern "C" for public definitions.
2728 With input from RVDM.
2730 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2731 Thanks to Ronald van der Meer (RVDM).
2733 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2735 Added support for private extensions to the OID database
2736 (oid_setprivateoids()). Thanks to RVDM.
2738 Added optional, physical ANY (key replication)
2740 Fixed null-reference problem in GRS-1 output filter.
2742 Proximity operator added to Prefix Query Format (PQF).
2744 In test client command "base" accepts multiple databases.
2746 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2750 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2752 Smallish bug-fixes in the new encoders/decoders (explain).
2754 Bug fixed in DeleteRequest.
2756 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2758 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2760 Added SOIF syntax (using private OID for now) to retrieval module and client.
2762 Added Update extended service.
2764 Added SearchResult-1 additional info structure.
2766 Added optional CCL (ISO8777) interpreter as separate module. Available
2769 --- 1.2 1996/6/10 (1st anniversary release)
2771 Added Summary record syntax. Lightly tested.
2773 Added OPAC record syntax. Untested.
2775 Added ResourceReport service encoders/decoders. Untested.
2777 Fixed bug in z_Unit - wrong tagging on unitSystem.
2779 Fixed bug in the DiagRecs decoder.
2781 Added options for max PDU size and session timeout to frontend-server.
2783 Added documentation of query-language parsers and other supporting utilities.
2785 [frontend-server] Added Attribute set to the bend_scanrequest API.
2787 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2788 surrogate diagnostics were generated.
2790 [retrieval] Allow multiple local values for attribute.
2792 [retrieval] Allow multiple attributes per element in .abs files. index type.
2794 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2796 --- 1.1pl2 1996/4/10
2798 Minor changes, mostly specific to Zebra's requirements (retrieval)
2802 Repaired bug in frontend server when running multiple listening
2803 endpoints in dynamic mode.
2805 z_External() now won't break if a known, ASN.1 value comes encapsulated
2806 in an octet-string. The value will pass through unmodified in an Odr_oct.
2808 Added a bit of code to the demo client to decode & display
2809 ASN.1-structured records represented in the octet-aligned branch of
2810 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2812 Added z_ext_getentbyref() to the ASN module. Doc updated.
2814 * Completed the SCAN definition in the ASN module. This may break SCAN
2815 code based on older YAZ-versions at compile-time. The fix is easy -
2818 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2819 under the SCAN definition. Remember to initialize this, server-people.
2821 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2822 that this does not extend to ODR and ASN.
2824 Comstack allows insertion of established socket (primarily for
2825 inetd-operation of servers). Doc updated.
2827 Front-end server can now start from the inetd in TCP mode. Doc
2830 --- 1.0pl4 1996/1/24
2834 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2835 the rank and record number.
2837 Adjustments to the frontend server.
2839 Fixed diagnostic BER dumper. It ignored the file argument.
2843 Various changes to retrieval module.
2845 Changed the union discriminators of the protocol files from enums to
2846 ints paired with #defines.
2848 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2851 *Changed operator in the RPN structure to 'roperator', again to avoid a
2854 Fixed problems in Explain decoders/encoders.
2856 --- 1.0pl2 1995/12/6
2858 Memory bug in log module fixed.
2860 --- 1.0pl1 1995/12/5
2862 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2864 Bug in Explain DatabaseInfo module fixed.
2866 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2870 The shift to v1.0 signals that we now consider the *core* functionality
2871 of YAZ reasonably stable (the core being more or less equivalent to
2872 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2873 tested (Explain not at all - though that will happen soonish).
2875 Minor changes to code to support Windows port.
2877 Various minor changes after we're getting to use GRS-1 & co. more.
2879 Added Espec-1 format.
2881 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2882 of the protocol and it cannot be selected when encoding (maps into 'string'
2883 when decoding). Needed to talk to some servers.
2885 Demo client can request simple element set names.
2887 Added Diagnostic Format encoders/decoders.
2889 Added simple Close handling to frontend server (no hooks for resource
2890 reporting yet), and demonstration client.
2892 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2894 --- 1.0b3 1995/08/24
2896 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2897 handled incorrectly when records were requested in the searchResponse. This
2898 will only affect you if you use the frontend-server.
2900 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2901 Test-client will ask for and print GRS1. Ztest will return dummy records
2904 Added Explain encoders/decoders to the service-level API. Untested.
2906 Added Extended Services: Item Order encoders and decoders to the Service-
2907 level API. Untested. We could use a recent copy of the pertinent bits
2908 of the ILL protocol to add those bits.
2910 Added diagnostic format 1 encoders/decoders to the service-level API.
2913 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2914 odr_cons.c, which causes a more correct output.
2916 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2917 was always set to 0 when no records were requested in the searchRequest.
2919 * Added better external-handling. This shouldn't harm old code that
2920 *encodes* externals. It can break code that looks for a
2921 'single-ASN1-type' representation, since those types that are known
2922 are now decoded immediately. Look at the SUTRS sample code in
2923 seshigh.c and client.c. Documentation updated.
2925 Handling of structured records in bend_fetchresponse. Length -1 marks
2926 structured record, type is deduced from format field.
2928 --- 1.0b2 1995/06/27
2929 Fairly quick maintenance release to add SUTRS support.
2931 Fixed handling of SUTRS records in the demonstration client.
2933 * Added format field to the bend_fetchrequest and bend_fetchresponce
2934 structures of the backend API (frontend server). When the record is
2935 returned, the value of the format field is mapped to an OID. The
2936 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2937 of the record. The special value VAL_NONE in the bend_request means
2938 that no specific format was requested by the client. Documentation
2939 updated accordingly. Test server (ztest) will return a fixed dummy
2940 SUTRS record if your client requests SUTRS.
2942 Documentation updated accordingly.
2944 You can now set external libraries and RANLIB support in the top-level
2948 First public release.
