3 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
7 Add new utilities to convert from CQL to CCL . These utilities have
8 prefix cql_to_ccl defined in cql.h.
10 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
11 lead to memory heap corruptions when ICU utilities were in use.
15 Make compilation work without Libxml2.
17 yaz-client: remove redundant blanks in display of searchResult-1 term
22 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
23 resulting CQL node (tree) in a new node CQL_NODE_SORT.
25 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
26 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
27 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
28 Note that the CQL sortby spec is only converted when the GFS is already
29 converting from CQL to RPN (cql2rpn element).
31 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
32 specify whether to collapse delimitors or not. The existing nmem_strsplit
33 do collapse (collapse parameter = 1).
35 Windows installer: For NSIS, set InstallDir depending on x86/x64.
37 Rename internal func yaz_use_attribute_create. While non-static, this
38 function is not declared in a public header.
42 Add -lCrun when linking with ICU on Solaris.
44 More quicks character set conversions for OPAC records.
48 fix problem with record_render: records were converted (character set
49 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
53 SRU: add methods for handling DADS SRU-proxy facets.
55 Separate OPAC record character set for ZOOM_record. yaz_record_render
56 allows a character set given as charset=from/opacfrom,to where 'from' is
57 the character set of a bibliographic record, 'opacfrom' is character set
58 of OPAC record and 'to' is the target character set.
62 yaz-client: show may XML format records. Command show followed by 'format'
63 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
66 src/stemmer.c: Avoid using unnamed union. It is not supported by some
69 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
72 Update yaz.spec to operate on both SLES11 / Centos 5.5.
74 RPM: Release includes 'indexdata' name. Use indexdata in release name so
75 this package can be distinguished from other vendors.
77 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
78 as determined by configure
80 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
82 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
83 returns no error and no record, the present request is considered
84 partial (only a subset of the records could be returned by backend), and
85 so it is appropriate to set Present Status to partial-4.
89 Move yaz-config man pages to section 1.
91 More documentation about SOLR.
93 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
94 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
95 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
96 peers on some Linux systems. However, in general that does not work
97 so YAZ can not rely on that to work. Debian changed behavior in this
98 respect from Debian lenny to Debian squeeze (still testing as of Oct
100 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
102 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
106 Fix yaz-config output: echo_source not set correctly by configure.
110 SOLR WebService support for yaz-client and ZOOM.
112 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
114 --- 4.0.12 2010/08/17
116 Z39.50 facet support. Facet specifications are passed for search in
117 other-information with ASN.1 as defined in facet.asn and OID
118 .10.1000.81.5 . Facets are expressed as an Attribute list as known
119 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
120 3 is limit (number of entries to get in response). yaz-ztest returns
121 dummy facets if a client asks for them.
123 --- 4.0.11 2010/07/09
125 CCL fixes: bug 2895 and bug 3539.
127 GR1-display: add comma in display - was removed by mistake in
130 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
132 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
134 --- 4.0.10 2010/06/18
136 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
137 result set from a connection. The result set will be on its own
138 thereafter; no operations on it will perform retrievals from a target.
139 Only cached copies are returned.
141 ZOOM C:fix case for HTTP servers responding with Connection:close.
142 Ensure that if there is a current task it is resumed (like fetching
143 more records in a result set) . Bug #3484.
145 PQF parser: use odr_atoi for Odr_int (not atoi)
147 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
148 values that contain any non-digits are treated as string attributes
149 (previously decoding only checked for leading character ([0-9]). PQF
150 encoding: attribute string values are not surrounded by double-quotes.
154 New utility for managing threads - thread_create.h.
156 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
157 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
158 but YAZ' implementation do.
160 Fixes for yaz_cond-functions on Windows 7.
162 DLL export more symbols.
164 zoomsh: show record do NOT render opac.
166 Remove *.la files from Debian and RPM packages.
170 Debian package libyaz-dev depends on libgnutls-dev again (was
171 removed in YAZ 4.0.6, but due to Libtool it is still needed
172 even though yaz-config do not list libgnutls libs).
174 ZOOM: Use only one WRBUF for returning string results for
175 ZOOM_resultset. Reduces memory usage for ZOOM in general.
177 ZOOM: ZOOM_connection do not use a shared pointer to
178 ZOOM_resultset after ZOOM_resultset is destructed by
179 user. Reverts to YAZ 4.0.4 behavior.
183 record-conv: fix problem with at least one XSL conversion -
184 due to probably incorrect usage of XML XSL documents.
188 Fix yaz-config for static mode and the use of SSL (gnutls).
192 Forward decl timeval struct in mutex.h and gettimeofday.h.
194 yaz-config: fix 'static' mode linking.
198 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
199 are wrappers for pthreads or Windows. For Windows these are put in
200 a separate DLL: yaz_cond4.
202 libyaz.la (whole source) is compiled with thread. If thread support
203 is enabled enabled, all source of YAZ is compiled with treading support.
204 This allows core utilities such as yaz_log to use thread facilities.
205 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
206 thread utilities. This commit moves mutex utilities (mutex.c) from
207 libyaz_server.la to libyaz.la.
209 yaz-json-parse displays leading text until error.
213 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
214 patch from Giannis Kosmas.
216 SRU: no longer URL encode SRU database. The URL for an SRU server is
217 a URL and such is alreeady encoded - at least when given with leading
218 http:// or https://. This reverts behavior to YAZ 3.0.50.
220 Support for new MARC XML notation TurboMARC which like MARCXML is a
221 complete representation of MARC/ISO2709.. This one, however, is more
222 compact and allows for faster processing with XSLT. TurboMARC can be
223 used in the marcdisp.h API, from the yaz-marcdump utility and from
226 yaz-ztest can be configured - via the database - to perform certain
227 delays when it performs operations search, present and single record
228 fetch. This allows testers to make yaz-ztest act as a real or even slow
229 Z39.50 server. Refer to the yaz-ztest man pages for details.
233 wrbuf_destroy allows NULL WRBUF passed to it.
235 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
237 Add ZOOM_connection_close.
239 No fixed size buffers for ZOOM shell - bug #3257.
241 tstodr: make it work on s390 platform.
243 New icu iterator-functions. The new icu_iter-functions makes it possible
244 to use ICU chains from many threads.
246 yaz-client: better syntax check for show command.
250 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
253 New simple local-file XML include facility which allows file glob-patterns.
254 Refer to yaz/xml_include.h.
256 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
259 ZOOM_record_get supports new parameter "format" which makes it format XML
262 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
263 JSONText in ECMA-262) is JSONValue, not JSONObject.
267 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
268 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
270 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
271 POSIX/Unix builds .so with major version 4.
273 Remove old LOG_-defines from log.h. They have been obsolete and
274 undefined by default for the last 5 years.
276 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
278 GFS: Remove socket (int *fd) from search_rr handler. The socket
279 descriptor ptr is a facility that allowed a search handler to supply
280 a socket which would serve as a callback - when search was complete.
281 This facility has now been in use for years.
283 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
284 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
285 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
286 returns 'const char *' rather than 'char *. The returned string is
287 read-only and should not be modified by applications. COMSTACK cs_close is
288 now a void function - it no longer returns int. No applications check for
289 the value and the implementations has always returned 0.
291 ZOOM: use size_t for scan hit counts and str size. Functions
292 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
293 occ (hit count) and len (string length) are now of type size_t pointer
294 rather than int pointer. This is to be able to represent large hit counts
295 and to also just to use the proper type for string length (strlen result).
297 New JSON parser. Refer to include/yaz/json.h .
299 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
300 Used to be int in some cases. Many wrbuf_-functions used to return an int
301 indicating some length.. These return values were never used. And so they
304 ODR: odr_malloc, odr_total now takes size_t for size.
306 clone_z_type: fix leak; occurred for encoding failures.
308 --- 3.0.52 2009/12/03
310 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
311 bug was introduced in 3.0.51.
313 --- 3.0.51 2009/12/02
315 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
317 tcpip comstack: fix leak for getaddrinfo.
319 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
320 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
321 Decoding of SRU "path" database is performed by private function
322 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
323 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
325 yaz-client: honor base command for SRU. Change when database setting
326 is applied for SRU and ensure it is kept when a connection is reset.
327 Change also the way errors are displayed or SRU (decoding of packages).
329 --- 3.0.50 2009/11/02
331 Add support for extra request / response data for SRU codecs and GFS.
332 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
333 for extra data response buffer and length. For the GFS, both request
334 and response data (XML) is carried in extra_args and extra_response_data
335 for the search handler. Patch by Ko van der Sloot.
337 ZOOM: For queries that cannot be converted to the specified rpnCharset,
338 ZOOM now returns a diagnostic on the client-side ('invalid query' /
339 10010). This fixes bug #2113.
341 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
342 cmdfile included a 'quit' command that would result in a memory violation.
344 --- 3.0.49 2009/10/01
346 Make a number of functions defined in xmlquery.c static. These have
347 never been declared in a public header file (yaz/xmlquery.h) and was
348 made public by mistake.
350 Improve speed of character conversions (iconv utilities). This makes
351 conversions from MARC-8 faster.
353 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
354 unless type desired is "raw". This will prevent type "xml" from
355 returning ISO2709 .. Which obviously can not be XML parsed.
357 Fix memory leak in ZOOM that would occur if option apdulog was used
358 on a re-used connection.
360 Frontend server logs HTTP requests.
362 Frontend server now sends Z39.50 close when it times out (sesssion has
363 been idle for too long). Versions 2.0.30 and earlier also sent close.
364 But due to a mistake this was disabled in all versions after that, i.e.
365 the server would just close the socket immediately.
367 yaz-client emits a better message when receiving an unrecognised
368 userInformationField.
370 Skip zero-length subfields when decoding ISO2709. This rare case happens
371 if a record has two FS characters in a sequence. Without this patch
372 there would be a reference beyond char array in using_code_len fragments
375 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
377 --- 3.0.48 2009/08/28
379 The show command offered by the zoomsh command now takes a 3d optional
380 parameter type which is what is passed to ZOOM_record. If the type
381 argument is omitted, "render" is used.
383 RPN to CQL conv may use USE string attributes (bug #2978).
385 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
387 --- 3.0.47 2009/07/08
389 Function yaz_xml2query allows a diagnostic element in the PQF XML
390 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
391 code and additional info respectively.
393 The BER BOOLEAN is now the integral type Odr_bool which still happens
394 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
395 typedef'd to Odr_int. This is still an integral 'int', but it may be
396 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
397 ASN-1 compiler as well as programs has been updated to use the new types.
399 --- 3.0.46 2009/06/08
401 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
402 only the bibliographic record was rendered. For type=opac, an OPAC
403 record is only returned if it is present.
405 iconv: small fix for encoding of advancegreek.
407 yaz-client: avoid double display of SRU/SRW records (bug #2798).
409 yaz-client: option auto_reconnect=on really reconnects.
411 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
413 server: avoid null ptr ref for for yaz_poll errors.
415 build: fix RPM build for RHEL 5.3.
417 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
419 --- 3.0.45 2009/03/31
421 Fixed bug #2709: TCP connect returns Invalid argument.
423 Fixed compilation for mingw.
425 Honor charset for raw records (ZOOM_record_get).
427 Fixed use of errno for threaded mode that was seen on Solaris 10.
429 Fixed argument passing with blanks in value for Windows Service.
431 Disable YAZ' own log rotate by default (no 1 GB limit).
432 The variable l_max_size which specifies the log file limit is set to 0
433 (DISABLED): This is due to the fact that YAZ is most often deployed using
434 logrotate. Also YAZ can not perform log rotate because of unsufficient
435 permissions (setuid).
437 --- 3.0.44 2009/02/17
439 List supported encodings in man page for yaz-iconv.
441 Fixed missing SSL libs for --libs output
443 Re-established OID record syntax application-xml. Nobody should use it
444 but we don't want to change soname because of this symbol being absent.
446 --- 3.0.42 2009/02/02
448 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
450 Added member named_result_sets for init handler struct for the GFS. This
451 allows a server to disable named result sets.
453 Removed OID record syntax application-xml.
455 Added support for rule-based transliterator for ICU wrapper of YAZ.
457 Fixed bug #1902: yaz-icu XML output.
459 Make YAZ checks Emacs friendly.
461 BITSTRING value shows value. Bug #2346.
463 ISO2709 decoding: skip control characters from indicator data.
465 Omit sort key by default in yaz-icu's output.
467 Allow combined single char options (again) for YAZ' options function.
469 Utility yaz-marcdump got option to display YAZ version (-V).
471 Allow YAZ to use ICU 3.4.
473 Added new ICU test case which illustrates removal of diacritics.
475 --- 3.0.41 2008/12/29
477 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
479 --- 3.0.40 2008/12/29
481 For configure, using option --without-xml2 also disables Libxslt/Libexslt
484 Fixed bug #2352: yaz-marcdump crashes for certain record.
486 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
488 Added support for Danmarc2 to UTF-8 conversion.
490 Added support for ISO5426 to UTF-8 conversion.
492 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
493 implementation version.
495 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
497 --- 3.0.38 2008/11/10
499 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
500 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
502 ZOOM C now interprets databaseName option for ZOOM connection as path
505 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
507 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
509 Dummy Libxml2 types no longer defined in headers of YAZ'.
511 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
514 --- 3.0.36 2008/09/26
516 Various ODR chapter fixes.
518 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
520 Added missing source for Windows compilation, mutex.c.
522 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
524 For SRU connections in ZOOM all records up to "count" are now fetched.
526 Fixed crash in generic frontend server (and yaz-ztest) which occurred
527 in Windows due to bad error handling for Libxml2.
529 Added facility for sending arbitrary records (ASN.1 any) using
530 ZOOM C's Extended service update. Patch by Sam Reynolds.
532 New options for ZOOM C's connection, logapdu which makes ZOOM log
535 --- 3.0.34 2008/06/18
537 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
539 --- 3.0.32 2008/06/12
541 Fixed memory violation that could occur when decoding UTF-8. This bug
542 was only present in 3.0.30 of YAZ.
544 --- 3.0.30 2008/06/06
546 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
547 GNU TLS is used by default (if found).
549 yaz-ztest returns OPAC records if a client asks for OPAC.
551 Improved speed of MARC-8 encoding.
553 Added support for lossy and loss-less MARC-8 encoding.
555 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
557 Added new Windows Service wrapper (sc).
559 yaz-client's itemorder command may now send a file.
561 Fixed yaz-marcdump to allow the use of NS prefix for record element.
563 Added new function yaz_log_xml_errors.
565 Allow (but warn) unknown XML attributes in MARCXML parsing.
567 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
569 The UTF-8 to MARC-8 conversion now uses a different set of characters
570 for Greek symbols. Bug #2120.
572 --- 3.0.26 2008/02/21
574 Added yaz_daemon (daemon.h).
576 Fixed bug #2068: pkg-config trouble
578 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
580 --- 3.0.24 2008/01/28
582 Document --with-xml2 option.
584 Added OPAC XML XSD (etc/opacxml.xsd).
586 Allow glob mask for name attribute in retrieval element for the
587 generic frontend server's retrieval facility.
589 Changed yaz_poll_poll to return yaz_poll_except for all returned events
590 except POLLIN/POLLOUT.
592 Fixed error handling in cs_listen. Bug #2037.
594 --- 3.0.22 2008/01/20
596 Fixed version in yaz/yaz-version.h.
598 Fixed bug #2027: Crash when closing connection.
600 Changed configure so that ICU support is only enabled if only ICU
601 and Libxml2 is available (because the ICU chain is XML based).
603 --- 3.0.20 2008/01/15
605 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
606 is built. Only this DLL depends on the ICU runtime.
608 yaz-ziffy is no longer part of YAZ. It is distributed separately by
609 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
611 Changed license of CCL module to 'Revised BSD'. After consultation with
612 remaining members of the original EUROPAGATE consortium, we are re-issuing
613 the CCL module without a separate license. The software was developed by
614 Index Data as part of a research project. The special license was included
615 to help feed usage information back to the project consortium to support
616 project evaluation. At this time, the project consortium has long-since
617 disbanded, and the majority of the original principals have retired. At the
618 same time, we have significantly modified the software during the following
619 years, to the point where very practically no original code remains. To
620 simplify re-use of the software, we have contacted those members of the
621 consortium who could be reached, and agreed to re-issue the module as a
622 proper part of the YAZ package.
624 Tcl scripts uses /usr/bin/tclsh as preferred shell.
626 CQL closer to being version 1.2 compliant. CQL also allows free-form
627 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
630 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
631 bug could make Extended services handling crash in the ZOOM layer. This
632 bug was only present in YAZ 3.0.18.
634 --- 3.0.18 2007/12/19
636 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
639 yaz-marcdump reads and writes collection wrapped records.
641 Handle OPAC for record conversion module.
643 Fixes for ICU wrapper.
645 Allow ICU libs to be controlled with --with-icu .
647 --- 3.0.16 2007/11/12
649 Added yaz_poll which is a wrapper for select/poll. When poll is available
650 and non-buggy, it is used, by yaz_poll . This allows more than 1024
651 sockets to be in use.
653 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
654 functionality through an XML based configuration (ICU chain). This system
655 is useful for search facilities such as Pazpar2 and Zebra that needs to
656 perform tokenization of indexed material. The ICU code in a separate
657 library libyaz3_icu.a.
659 Added HTTP tunnel facility for COMSTACK, bug #1752.
660 This is a facility that allows a Web proxy, such as squid, to tunnel
661 Z39.50 traffic. This facility is "transparent" to must applications
662 using YAZ. It's enabled by using pseudo transport connect: followed by
663 the proxy address, followed by command, then follwed by he regular
664 "virtual" addresss. For example,

667 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
669 --- 3.0.14 2007/09/21
671 Fixed bad memory reference in ZOOM_record - cuased by member not being
672 initialized. This was a problem only in YAZ 3.0.12.
674 Fixed bug in conversion from MARC to XML: Non-XML characters in control
675 fields were not removed.
677 Changed the way C code is generated from codetables.xml. Made a MARC-8
678 conversion trie for each characterSet section rather than codeTable.
679 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
680 of codetables.xml from Larry Dixson, LOC. Bug #1464.
682 --- 3.0.12 2007/09/12
684 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
685 from ZOOM_record_error).
687 ZOOM C function ZOOM_record_get returns record schema for type="schema".
689 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
691 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
693 Better SRW-to-Bib-1 diagnostic mapping.
695 ZOOM C and yaz-client announces SRU version 1.2 by default.
697 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
700 Fixed in yaz_sru_decode to allow other version than 1.1.
702 --- 3.0.10 2007/08/22
704 Added support for SRU scan for ZOOM.
706 Added support for the use of the older versions or Extended Service
707 Update in ZOOM. To faciliate this, an option "updateVersion" may be
708 set to the version , 1=first, 2=second, 3=third. The third version is
709 what ZOOM C has used so far. And that, obviously, is the default.
711 Added support for CCL queries in Z39.50 queries sent to the GFS (and
712 therefore in Zebra and in SimpleServer-based applications). The new
713 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
714 qualifier file used to transform incoming CCL queries into Type-1 RPN,
715 which is passed into the back-end search callback function.
717 Added support for HTTP Basic authentication in clients: the SRU/W
718 codec encodes the username/password elements of the PDU structure
719 appropriately, and these may be set using the "user" and "password"
720 options in ZOOM-C applications (the same options that are used for
721 Z39.50 authentication).
725 Fixed bug #1208: SSL appears to be broken in ZOOM.
727 Fixed bug #1206: Libxml2 include path weirdness.
729 Added oid_name_to_dotstring.
731 Allow elementSetName to be specified for ZOOM C record update.
733 Allow waitAction to be specified for ZOOM C based for Extended Services.
735 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
736 syntax OID. Bug introduced in YAZ 3 series.
738 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
742 Fixed bug #1157: yaz-client does not read .yazclientrc from current
743 directory. yaz-client now reads commands from file given by option -f
744 if specified; then tries to read .yazclientrc in current directory.
745 Failing that, it reads .yazclientrc from user's home directory.
747 Added support for correlationInfo Note and ID for Record Update via
750 Added yaz-client command querycharset which specifies character set for
751 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
752 (termListAndStartPoint).
754 Charset ISO5428:1984 is an alias for ISO5428-1984.
756 Implemented a way to perform scan in a result set using Z39.50. This
757 is achieved by attaching the result set name in the characterInfo
758 (type InternationalString) of OtherInformation in the Scan Request PDU.
759 The result set is identified in the otherinformation by the new OID:
760 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
761 This allows for scan in result set and faceted search . Zebra did some
762 of this in the APT term using attribute type 8 and value being result
763 set. Using the OtherInformation approach for this is cleaner and easier
764 to work with in proxies and the like. This facility can be used in
765 yaz-client using new command setscan which takes a result set as first
766 argument, start position (APT) as second.
768 Changed decoding of SRU XML packed records to deal with servers that
769 have recordData with XML data with multiple root nodes. Also make
770 comparison for recordPacking case insensitive. Again, one server
771 returns "XML" where others return "xml".
773 For SRU responses allow Content-Type application/xml as well as text/xml.
777 Fixed bug in character set conversion of BER strings. Bug introduced
782 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
784 For OID class, use oid_class consistently.
786 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
789 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
790 character set for bibliographic information interchange". By Giannis Kosmas.
792 Added documentation on new OID API.
796 Changes to generic frontend server interface: added new member
797 'query_charset' for bend_initrequest structure. A backend init handler
798 should set this member to its native character set for query terms.
799 When defined, the frontend server logic will announce this character set
800 to a client if the negotiationModel bit is set by the client. All server
801 implementors are encouraged to specify this. If a backend server does not
802 specify this a warning is issued using yaz_log(YLOG_WARN,..).
804 Added CCL utility to remove terms (stop words) from resulting RPN
805 tree. This is handled by functions with prefix ccl_stop_words_ .
807 New ZOOM C option, "rpnCharset", which allows client-side conversion of
808 terms in RPN queries.
810 Clean-up the CCL API. Moved some internal structures from ccl.h to
811 private header cclp.h. Changed ccl_parser_create so that a Bibset must
812 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
813 This is replaced by ccl_parser_find_str which takes a string instead.
815 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
816 libyaz.la is the core of YAZ except the generic frontend server and
817 does not depend on POSIX threads anymore. libyaz_server.la is the
818 generic frontend server facilities and uses POSIX thread functionality
819 if available. The libyaz.la no longer depends on POSIX threads because
820 the number of global structures is limited. NMEM no longer re-uses blocks
821 between threads ; it simply free's memory immediately but allocates in
822 "large" chunks as usual. We don't expect any performance penalties
823 because of this. The yaz_log system is still using a global log_level so
824 caution must be taken when modifying it with yaz_log_init_.. +
825 yaz_log_mask_str. This, however, should not cause any trouble because
826 these functions are called during initialization of application code
827 anyway. `yaz-config --libs server` returns libs for server applications;
828 `yaz-config --libs` returns libs for non-server applications.
830 New OID database - with public definitions in oid_db.h. Removed old OID
831 database including the head oid.h and definitions such as enum oid_value
832 and struct oident. The new OID database uses the same string names as
833 before but the 'protocol' is gone. There are now only two representations
834 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
835 converts from string to OID; functions with prefix yaz_oid_to_string
836 converts the other way.
838 Change to emit_term() in CQL-to-PQF query translation: when a term has
839 the /regexp relation modifier, do not process it for leading and
840 trailing "^" and "*", which have quite different meanings in regular
843 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
844 write handlers no longer carries a 'last' parameter. This will make
845 yaz_iconv flush "less" characters. A flush is performed by call to
846 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
848 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
849 removed, because function yaz_query_to_wrbuf does the same.
851 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
852 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
854 Deprecated MARC utility functions removed.
856 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
859 Branch split: YAZ_2_1_55_branch
861 --- 2.1.54 2007/03/16
863 Fix to ZOOM-C so that transparent reconnection is properly handled on
864 connections that are in asynchronous mode.
866 Fixed compilation on OpenBSD 4.0.
868 Large strings in GRS-1 records are now properly displayed in yaz-client.
870 Added character conversion support for "advancegreek"; based on patch from
873 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
874 sequence is met. Before the error was not set so it would be unknown.
876 Adjust yaz-marcdump MARC reader so that it skips until record separator
879 --- 2.1.52 2007/03/07
881 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
882 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
883 fd_set structure used as a bitmask for the FDs to be selected on.
885 Using ACX_PTHREAD macro to check for POSIX threads.
887 Fixed have-vsnprintf check.
889 --- 2.1.50 2007/02/23
891 Fixes for configure on BSD. Bug #900.
893 Added snprintf/vsnprintf wrappers for systems that don't have
894 limits (heavens forbid).
896 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
897 created before all previous tasks were completed and removed from the
898 task queue, the new task could be removed by a mistake.
900 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
902 Implemented pass-through CQL-to-PQF conversions. Bug #861.
904 Fixed bug #832: Problem with MARC/charset in yaz-client.
906 Fixed bug #668: save command line history for yaz-client.
908 Fixed bug #830: pkg-config support.
910 --- 2.1.48 2007/01/23
912 Extended ZOOM result set options with two options that may be read by
913 a client: resultSetStatus and presentStatus with values as specified for
915 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
917 Fixed bug #827: Using SSL fails on Debian etch.
919 Fixed bug #826: Weird looking chars for set of MARC records.
921 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
922 that is treated as an ItemOrder with itemRequest being an XML document
923 external. The value of "doc" is the content.
925 Extended the GFS search facility. New member of bend_search_rr
926 'estimated_hit_count' signals that hits is known to be an estmate
927 (higher or lower than real hit count). New member 'partial_resultset'
928 signals that the search was partial (hit count is lower or equal than
929 real hit count). For Z39.50, the information is stored in resultSetStatus
930 member of SearchResponse APDU. For SRU, the information is signalled
931 via SRU diagnostic 59: "Result set created with valid partial results
934 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
936 --- 2.1.46 2007/01/13
938 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
940 Added ZOOM_connection_peek_event.
942 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
943 the following new functions:
944 ZOOM_event_nonblock, ZOOM_connection_process,
945 ZOOM_connection_get_{socket,mask,timeout},
946 ZOOM_connection_fire_event_{timeout,socket}.
947 The existing blocking event handler, ZOOM_event, is a wrapper for the
948 + blocking ZOOM_event_sys_{poll,select}.
950 Implemented function ccl_xml_config which parses XML version of CCL
951 configuration (bug #798).
953 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
955 Added timings utility (yaz/timing.h)
957 --- 2.1.44 2007/01/03
959 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
962 Fixed bug #779: Rotation of apdu.log fails.
964 Fixed for character set conversions:
965 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
966 Honor G1 set in MARC-8 decoding.
968 --- 2.1.42 2006/12/17
970 Fixed bug #775: char conversion does not handle Alternative UTF-8
973 Implemented function yaz_marc_read_line which parses MARC line format
974 records. There is a wealth of formats out there. So far, this function
975 reads line records produced by yaz_marc_write_line.
977 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
978 more generic and easier to remember(!) options: -i format and -o format
979 which specifies input format and output format respectively - where
980 format is one of "marc", "marcxml", "line", "marcxchange".
982 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
983 does not print anything except warnings for records.
985 For yaz-marcdump, added support for MARC split into files (-s) with a given
988 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
989 spec, at http://www.loc.gov/standards/sru/record-update/
990 This has changed the binary layout of the following structs:
991 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
992 bend_update_rr . Patch by Ko van der Sloot.
994 Added GFS utility function bend_assoc_is_alive which returns 1 if
995 association is still alive (client is connected); 0 otherwise (client
996 closed connection). This allows busy servers to stop working for
999 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1000 been a separate piece of software. This version of ziffy has been modified
1001 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1003 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1005 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1006 Client code may now interrogate options such as "init_opt_sort" to
1007 find out whether the server claims to support various options.
1009 --- 2.1.40 2006/11/27
1011 Added utilities yaz_{set,get}_esn to set/get element set name from
1014 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1015 of YAZ and has been so since YAZ 2.1.10.
1017 Implemented ZOOM_record_error which returns error information for
1018 record (surrogate diagnostic).
1020 --- 2.1.38 2006/10/31
1022 Updates for SRU Update by Ko van der Sloot:
1023 1. Changed name from "operation" to "action"
1024 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1025 versions in the code, marked as 'backward compatible'.
1026 3. Added diagnostics for SRU Update.
1028 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1030 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1032 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1034 For GFS, fixed problem with SRU diagnostic 'First record position out of
1035 range' being issued for 0 hits.
1037 zoomtst10 part of Windows Build.
1039 --- 2.1.36 2006/10/13
1041 Implemented yaz_filepath_comp which splits a path into file path
1042 components (required by Zebra 2.0.3+).
1044 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1045 BSD inspired license until now so this should not have any real impact on
1046 anybody. See http://www.opensource.org/licenses/bsd-license.php
1048 Fixed bug #687: Missing log lines.
1050 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1053 Fixed bug #689: SRU diagnostics to be added.
1055 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1056 whether a connection is idle (no more work do do).
1058 --- 2.1.34 2006/10/04
1060 Change type of optval from long to int for invocation of setsockopt with
1061 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1063 Added support for specifying the max log file size for the Generic
1064 Frontend Server. The size is given with option -r.
1066 --- 2.1.32 2006/09/21
1068 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1070 --- 2.1.30 2006/09/17
1072 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1075 Fixed bug in Generic Frontend Server that could cause a server to stop
1076 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1078 For the generic frontend server, the maximum record size is used as maximum
1079 size of incoming packages (SRU + Z39.50). The value until was previously
1080 only used in Z39.50 Init negotiation and, later, in a session controlled
1081 sizes of records returned. This is controlled using -k option. It can be
1082 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1084 --- 2.1.28 2006/09/04
1086 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1089 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1091 New option for yaz-marcdump -lpos=value which allows setting a portion
1092 of MARC header to a certain value.
1094 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1096 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1097 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1099 --- 2.1.26 2006/08/15
1101 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1104 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1106 --- 2.1.24 2006/08/08
1108 Fixed MARC ISO2709 encoding routines to deal with character set
1111 Minor changes to GFS logging. Database included in search request log
1114 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1115 cached/multiple records.
1117 Shared libraries are built by default on Unix+configure.
1119 Changed cql2pqf transformation to use a different evaluation order. The
1120 new order is: always, relation, structure, position, truncation, index
1121 and relationModifier. Old order was: always, relation, relationModifier,
1122 structure, index, position, truncation. Note that the the latter ones
1123 override former ones for identical attributes.. The new scheme means that
1124 it is possible to override any existing attribute with a relationModifier.
1125 And also that it is possible to override everything for the index rule
1126 (except the ones listed in relationModifier). No order is perfect but this
1127 one, we believe, covers more real cases.. The "always" should have been
1128 called "default", since the attributes there can be overridden with all
1131 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1132 compilation phase, but also for yaz-config --cflags output. This allows
1133 us to have public headers with Libxml2 stuff in them . It should also,
1134 eventually, make Libxml2 checks redundant in packages using YAZ, such
1137 --- 2.1.22 2006/06/15
1139 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1140 stored in uri, message and details.. Previously diagnostics were stored
1141 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1142 compatibility.. but he's probably the only one affected, so.
1144 Added support for CCL, compiled on the client side, in ZOOM-C. This
1145 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1146 input; the resulting query objects can be used for for searching with
1147 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1149 YAZ' configure searches for OpenSSL by default.
1151 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1152 SL_CTX_use_certificate_file. See
1153 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1154 for more info. Thanks to Ko van der Sloot.
1156 --- 2.1.20 2006/06/02
1158 Bug #600: SRU GET, POST support for yaz-client. Introduced
1159 command 'sru' which selects method SOAP/GET/POST.
1161 Allow missingValueAction to be specified for the sortspec string -
1162 function yaz_sort_spec. By default, the missing value action is null.
1163 Use ! to specify "abort". Use = followed by stringvalue to specify default
1166 Ensured that Present-handler (if defined) is called in GFS before any call to
1167 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1168 searchRetrieve requests.
1170 Documentation for YAZ is now based on the Docbook XML/XSLT using
1171 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1172 is no longer depending on jade/openjade or docbook-to-man scripts.
1173 PDF is no longer part of the distribution - but can optionally be
1174 made using DSSSL/jadetex or FOP.
1176 Added retrieval handling support in Generic Frontend Server to support
1177 conversion between MARC/XML as well as XSLTtransforms. See
1178 etc/yazgfs.xml for an example.
1180 Added Authentication support to Generic Frontend Server in SRU
1181 mode. Authentication using HTTP Basic is supported, as is the use
1182 of 'x-username' and 'x-password' parameters in the request itself.
1184 Added support for a new character set MARC8s identical to MARC8 except
1185 that it converts combined characters to single Unicode characters in the
1186 Latin-1 range (when possible).
1188 --- 2.1.18 2006/04/24
1190 ASN.1 compiler 0.4: generates brief Doxygen file header for
1191 generated .h/.c files.
1193 Utility yaz_iconv now supports conversion to MARC-8.
1195 New facilities for the MARC module. The reading - and writing of
1196 content are separate methods for the yaz_marc_t handle. The following
1197 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1198 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1199 format). Write functions have prefix yaz_marc_write_.. The existing
1200 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1201 available. Removed support for OAI-MARC and simplexml (not the
1202 simplexml from PHP5).
1204 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1205 to be returned for this connection.
1207 --- 2.1.16 2006/03/31
1209 Allow multiple languages and charsets to be specified with
1210 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1211 negcharset iso-8859-1,utf-8
1213 Translation of proximity nodes from CQL into PQF now works.
1215 Moved to automake 1.8, 1.9.
1217 Added function yaz_log_set_handler which allows a log handler to be
1218 installed. This handler will be called for all log messages. Output
1219 to file is also produced; but that can be disabled by passing NULL
1220 fname to yaz_log_init_file.
1222 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1224 For SRW (including GFS), accept application/soap+xml as content-type
1227 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1228 produces NO stylesheet reference even if a default stylesheet is specified
1231 --- 2.1.14 2006/03/14
1233 Updated Windows package to include yazd.dll + yazd.lib for the
1234 Development component.
1236 If the environment variable YAZ_LOG is set, then it is used as a
1237 string indicating the default level of logging to use if not
1238 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1239 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1240 used as before. So, for example, to omit warnings from YAZ logging,
1241 export YAZ_LOG=-warn
1243 cql_transform() now map structure and other attributes before indexes,
1244 so that index-specific structures and other attributes can override
1245 defaults. So now a combination of mapping specifications such as:
1247 index.dc.date = 1=date-modified 4=5
1248 does the right thing.
1250 cql_transform() now also respects the "always" mapping specification,
1251 which establishes an initial set of attributes to be used for all
1252 terms except where overridden by more specific attributes associated
1253 with the index, relation or modifier.
1255 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1256 which mode to use; one of "post", "get" or "soap" (SRW, default).
1258 Fixes for yaz_iconv routines: changed trie-based character set conversions
1259 to use only non-negative values for bit fields due to Sun's C compiler not
1260 supporting negative values.
1262 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1263 sequences where not read correctly. Fix by Rustam Usmanov.
1265 Updated win/makefile to use options, settings which makes things
1266 compile with VS C 2005.
1268 --- 2.1.12 2006/02/01
1270 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1272 In ZOOM socket code, use select instead of poll on MacOSX.
1274 ZOOM-C now support client-side compilation of CQL into RPN that is
1275 sent to the server, enabling CQL to be used against all Z39.50
1276 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1277 ZOOM_query object, and submit it using ZOOM_connection_search().
1278 The CQL-to-RPN translation uses a configuration file, the name of
1279 which must be specified in the Connection's "cqlfile" option.
1281 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1282 function, which takes as its start-term parameter a ZOOM_query object
1283 (which may have had either CQL or RPN set into it).
1286 --- 2.1.10 2005/11/29
1288 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1289 GFS to support this as well. Backend handler, bend_srw_update, does the
1290 update work. Code contributed by Ko van der Sloot.
1292 Allow retrieval of Search Result-1 information in ZOOM by the use of
1293 options that are attached to a result set. ZOOM documentation updated
1296 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1297 UTF-8 conversion. Patch by Raj Patel.
1299 Added option -m to GFS to control formatting of timestamps in log file.
1301 Added 'exit' as synonym for 'quit' in yaz-client
1303 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1304 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1305 for the new members. Patch by Ko van der Sloot.
1307 Added support for SRU POST. It is supported for content-type
1308 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1310 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1311 Instead make the library libyaz.la multi-threaded. Threading as a whole
1312 can still be disabled by configure option --disable-threads. Previosly,
1313 with older GLIBCs there were problems with MT libs under Apache. This
1314 has now been fixed a long time ago.
1316 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1319 CQL module modified to be case insensitive for relations/indexes/operations.
1321 Fixed bug in CQL transform code: incorrect value relationModifieder
1324 Added 'show all' command for yaz-client which retrieves all results
1327 Added new yaz-client, xmles, which takes a (private) OID and
1328 a document to be sent as an extended service request.
1330 Describe new yaz-client commands wait_response and set_auto_wait.
1332 Increase TCP/IP listener backlog from 3 (which I am guessing was
1333 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1334 that the socket will queue as many incoming connections as it's able
1335 to handle ongoing connections. In other words, it will never now
1336 refuse a connection that it would be able to handle merely because
1337 it's not got around to accepting() enough of the pending connections
1338 yet. This is the behaviour anyway under Linux, where the listen()
1339 argument is ignored; but not under BSD and on systems such as
1340 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1341 YAZ-based servers should now be uniform across operating systems in
1344 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1345 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1346 This allows yaz-marcdump to read large MARC batches (>2 GB).
1348 Modified all YAZ source files - except the source which is auto-generated
1349 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1352 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1353 corresponding to the existing *_setl() function. These allow option
1354 values containing arbitrary valuues.
1356 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1357 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1358 except that it returns an indicator of whether or not the sort
1359 criterion was accepted (0 for OK, -1 for invalid).
1361 --- 2.1.8 2005/06/07
1363 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1364 MARC output rather than returning "new" buffer.
1366 yaz-client warns about unknown init options.
1368 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1370 --- 2.1.6 2005/05/24
1372 Added support for SRW sort in Generic Frontend Server. Patch
1373 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1374 sortKeys - or NULL if none is provided.
1376 Fixed bug #307: It was impossible to specify indefinite/no timeout
1377 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1380 Added support for multiple languages and charsets to be specified in
1381 ZOOM. Each charset/language is separated by a blank. If negotiation is
1382 in effect in init-response, Option
1383 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1384 Code based on patch by Vasiliy Osadchuk.
1386 Fixed bug #306: infinite recursion that occurred when calling
1387 yaz_log_level_init as the first call (before other log level or
1390 Fixed bug in scan handling in front end server: if preferred-Position-In-
1391 Response was non-present, a NULL pointer referece was performed.
1393 --- 2.1.4 2005/04/26
1395 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1396 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1397 now defined for all those error codes. So instead of putting 109 in
1398 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1399 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1401 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1404 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1406 Program yaz-client now exits and produces an error message if multiple
1407 Z39.50 servers are specified on the command line (none or one allowed
1410 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1413 --- 2.1.2 2005/03/16
1415 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1417 Fixed bug #272: Preserve spacing for CCL terms.
1419 --- 2.1.0 2005/03/14
1421 Added support for virtual hosts and multiple backend servers for
1422 the YAZ frontend server. The configution is XML based and
1423 support specificition of CQL to RPN mappings and explain information.
1424 See section "Virtual Hosts" in the YAZ manual.
1426 Extended OPAC display utility. OPAC display utility renders
1427 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1428 to supplement yaz_marc_decode_wrbuf.
1430 Fixed a bug in MARC decoder that could caused it to crash for some
1431 invalid MARC records. More diagnostics and warnings where added in
1432 XML output (warnings, etc are stored in comments).
1434 --- 2.0.34 2005/02/08
1436 Fixes for UNIX domain sockets. Bug #261.
1438 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1440 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1441 Added yaz_marc_subfield_str which defines subfield lead string which is
1442 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1443 yaz_marc_endline_str which defines end of fields string used in
1444 YAZ_MARC_LINE format. Default string is newline.
1446 Experimental support for MarcXChange. This format can be produced
1447 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1448 http://www.bs.dk/standards/MarcXchange.xsd
1450 Added yaz-client commands scansize that sets maximum number of
1451 entries to be returned by scan.
1453 --- 2.0.32 2005/01/11
1455 Added support for SRW scan in yaz-client and Generic Frontend Server.
1457 * Added whereInList member to SRW Scan Term.
1459 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1461 Fixed NMEM system to return aligned blocks on the smallest boundaries
1462 that are suitably aligned for all possible types on the particular
1463 architecture YAZ is being built for.
1465 --- 2.0.30 2005/01/04
1467 Fixed numerious warnings that was issued with newer versions of GCC.
1469 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1470 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1473 Make YAZ Generic Frontend Server slightly faster.
1475 Enhance (and reduce) logging for Generic Frontend Server.
1477 Revert YAZ log system so that it flushes every write operation
1478 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1480 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1481 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1482 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1483 will effectively disable old definitions.
1485 --- 2.0.28 2004/11/09
1487 Added yaz_log_time_format which specifies log format using
1490 Added yaz_log_module_level which returns mask for a module. Value
1491 is non-zero mask a if module is enabled; zero if disabled.
1493 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1494 in include/yaz/cql.h.
1496 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1498 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1500 Fixed bug #172: RPM builds does not enable SSL.
1502 Doxyfile.in part of dist. Doxyfile generated by configure.
1504 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1505 are given and the corresponding component does not exist.
1507 Extend CCL documentation in YAZ reference. Describe r=r.
1509 --- 2.0.26 2004/10/01
1511 Fixed MARC->MARCXML conversion to properly deal with
1512 fields, subfields, indicators having non-ASCII characters.
1514 Fixed MARC->MARCXML conversion so that ASCII control characters
1515 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1518 Added YAZ GFS support for conversion from Z39.50 surrogate
1519 diagnostics to SRW surrogate diagnostics.
1521 Bug fix: YAZ GFS did not return schema in explainResponse.
1523 --- 2.0.25 2004/09/30
1525 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1526 now converts recordSchema to elementSetName as well as schema URI.
1528 Fixed bug in COMSTACK that prevented HTTP request packages from being
1531 --- 2.0.24 2004/09/29
1533 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1534 does not require white-space before and after the dash in a range, e.g.
1535 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1538 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1539 due to new GCC removing "redundant" code.
1541 Added yaz-client commands scanpos and scanstep that sets preferred
1542 position and step-size for scan.
1544 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1546 Added CCL utility ccl_qual_buf which parses one or more CCL
1547 spec lines in a buffer.
1549 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1550 of name and value - ignoring empty lines and comments.
1552 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1554 Added odr_get_element_path which returns current element path for an
1555 ODR handle. This utility is useful in error handling or user-defined
1558 Added ODR_PRINT utility odr_set_stream which is is a more generic
1559 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1560 to a write function and pointer to close function. The close function - if
1561 non-NULL - will be called during odr_destroy.
1563 Fixed bug in CCL parser where truncation char was not removed from
1564 right side when truncation=both was in effect.
1566 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1569 --- 2.0.23 2004/08/11
1571 Fix buffer overrun in CQL parser when dealing with proximity (%).
1573 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1574 to UTF-8/UCS conversion is now only based on codetables.xml.
1576 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1578 --- 2.0.22 2004/08/06
1580 Add support for more "commit changes" in ZOOM (uses Extended Services).
1582 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1585 Yet another small fix for configure of SSL.
1587 --- 2.0.21 2004/05/14
1589 Fix SSL libs for configure when --with-openssl=DIR is given.
1591 --- 2.0.20 2004/05/10
1593 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1595 SSL comstack now uses yaz.pem certificate file on server side
1596 by default. Certificate filename can be configured by calling
1597 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1599 Fix bug regarding multiple calls to ZOOM_connection_connect.
1601 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1603 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1604 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1606 ZOOM now allows inspection of X509 peer certificate for verification.
1607 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1609 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1610 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1611 as "modular" but it simplifies things.
1613 Added cs_get_peer_certificate to that returns peer X509 PEM.
1615 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1616 NULL if SSL is unavailable.
1618 Documentation about MARC decoding tools.
1620 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1622 --- 2.0.19 2004/03/30
1624 Rename CHANGELOG to NEWS to follow GNU style packing.
1626 Fix bug with missing initialization of member in init_diagnostics.
1627 This bug affects threaded version of GFS server.
1629 --- 2.0.18 2004/03/20
1631 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1634 Ensure zlib.dll is packed with Windows install.
1636 --- 2.0.17 2004/03/17
1638 Fix encoding of xsd:string to use text instead of CDATA.
1640 Fix endless loop in CQL parser with unbalanced ".
1642 Use a more compact way to store MARC-8 conversion tables.
1644 --- 2.0.16 2004/03/16 Debian only
1646 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1649 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1654 --- 2.0.15 2004/03/01
1656 Another fix for decoding of XML packed records.
1658 --- 2.0.14 2004/02/25
1660 Fixes for Chunked encoding. White space not ignored after length spec.
1662 Update NS and use default NS for SRW diagnostic elements.
1664 --- 2.0.13 2004/02/23
1666 Implement ZOOM_resultset_cache_reset which resets record cache.
1668 Implement ZOOM_resultset_sort which sorts a result set.
1670 Implement chunked HTTP transfer.
1672 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1674 --- 2.0.12 2004/02/16
1676 Added member 'schema' to bend_explain_rr structure so that backend
1677 can specify explain record identifier. Defaults to Zeerex 2.0.
1679 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1681 --- 2.0.11 2004/02/16
1683 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1686 Added init command for yaz-client which sends "extra" init request.
1688 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1689 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1691 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1693 Make ZOOM error code for "invalid query".
1695 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1697 --- 2.0.10 2004/02/05
1699 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1702 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1704 Added option -p <file> to make Generic Frontend Server to write PID file.
1706 Added option -D to put Generic Frontend Server in background on its own.
1708 Make ZOOM C recognize option "password". If unset, "pass" is used
1709 (for backwards compatibility).
1711 Fixed a bug in Generic Frontend Server that could make it crash if a
1712 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1715 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1716 Must be issued before open, in order to be in effect.
1718 --- 2.0.9-6 2004/01/12 Debian/Windows
1720 Make the SRU server more picky WRT unknown params, etc.
1722 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1724 New YAZ client command, options, that sets Z39.50 options.
1726 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1727 options from a string of tokens (one token for each option bit).
1729 Update SRW diagnostic code messages.
1731 --- 2.0.9-5 2004/01/07 Debian/Windows
1733 Handle user defined stylesheet for SRW/SRU.
1735 --- 2.0.9-4 2004/01/06 Debian/Windows
1737 Fix bug in decoding of Content-Length.
1739 --- 2.0.9-3 2004/01/06 Debian/Windows
1741 Fix a bug with decoding of XML packed records.
1743 --- 2.0.9-2 2004/01/05 Debian only
1745 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1747 Fix bug in SRW/SRU diagnostics decoding.
1749 --- 2.0.9 2004/01/05
1751 Fixed bug in Generic Frontend Server which could drop records exceeding
1752 preferred message size. Reported and fixed by Irina Dijour.
1754 Fixed calculation of package size for structured records in Generic
1755 Frontend Server. Reported and fixed by Irina Dijour.
1757 Fixed namespace for SRW/SRU diagnostics.
1759 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1761 --- 2.0.8 2003/12/22
1763 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1764 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1767 CQL changes to reflect recent changes to the specification:
1768 * Documentation talks about context sets instead of index sets.
1769 * Documentation talks about indexes instead of qualifiers.
1770 * The CQL-to-PQF transformer's configuration file now uses
1771 "index.set.name = <attributes>" instead of the old form
1772 "qualifier.set.name = <attributes>". (Both forms are still
1773 understood but the latter is deprecated.)
1774 * CQL terms with no explicit index specified are now interpreted as
1775 cql.serverChoice instead of srw.serverChoice (which of course
1776 behaves exactly the same.)
1778 --- 2.0.7 2003/12/16
1780 MARC conversion can now generate ISO2709 output in another
1781 character set. yaz-marcdump uses this facility if you invoke it
1784 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1785 functions from there can be used from C++.
1787 --- 2.0.6 2003/12/04
1789 Frontend server now transfers memory from decoded packages to stream
1792 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1793 references to show up.
1795 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1796 the ZOOM Abstract API. The older names for the same options are still
1797 also supported for the benefit of old applications.
1799 ZOOM-C supports "implementationId" and "implementationVersion" options
1800 to go along with "implementationName". These allow the user code to
1801 specify identification strings to be sent to servers.
1802 Add OID for the new ExtLite attribute set.
1804 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1805 as requested/supplid by Ere Maijala <ere@atp.fi>
1807 For generic frontend server, reverse the order of
1808 "toolkit-supplied / application-supplied" strings sent as implementationId,
1809 Name and Version. Also, remove the spaces around the slash. This brings
1810 the GFS in line with the behaviour of ZOOM-C on the client side.
1812 Add function ZOOM_scanset_display_term.
1814 yaz-client shows scan displayTerm if present.
1816 Utility yaz-iconv is now installed by default along with the man page
1819 Extend configure check for OpenSSL to use pkg-config where available (such
1822 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1823 server to specify uid/gid/mask for socket using the format
1824 unix:[user=uid,][group=gid,][umask=mask,]file=path
1825 If file= is omitted the existing format is assumed, e.g.
1827 in which case the mask is 0666 (rw for everybody).
1829 Major restructure of YAZ source. All source in libyaz is in src directory.
1830 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1831 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1833 Added man page for utility yaz-marcdump (used to be called marcdump).
1834 yaz-marcdump is installed by 'make install'.
1836 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1837 of incoming package failed.
1839 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1841 Change prototype of odr_perror: add const to message string.
1843 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1845 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1846 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1847 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1848 DNS lookup. There should not be any compatibility problems with this
1849 assuming that blocking=1 or 0 is used.
1851 Fix bad reference in UNIX comstack in function cs_addrstr.
1853 Fix for compilation on AIX.
1855 The generic front-end server (server/seshigh.c) now supports returning
1856 Init diagnostics to the client in User-information-field, in
1857 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1860 --- 2.0.4 2003/09/04
1862 Allow any CQL relation (not just all,any,exact,scr).
1864 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1865 that features the same UI.
1867 Implemented command update0 in YAZ client which is equivalent to
1868 update but uses old of Ext Update ASN.1.
1870 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1871 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1872 Previously no OID was used for this info.
1874 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1875 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1876 returns 'malformed search term' otherwise.
1878 SortResponse member resultCount now set to NULL in sort handler of
1881 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1884 Add three new utility functions for translating OIDs between various
1885 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1886 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1887 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1888 char *oid_to_dotstring(const int *oid, char *oidbuf);
1889 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1891 Reverted modifications for ES Update definition for z_IU0Update
1892 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1893 is back to YAZ 2.0.2.
1895 String value attributes for CCL parser.
1897 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1898 which their FirstSearch server returns in Init responses, sometimes
1899 carrying useful diagnostic information when Init fails. This has the
1900 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1901 "z39.50/oclcui.asn", where its definition is somewhat different from
1902 what OCLC document on their web-site, as required to interoperate with
1905 Support for anonymous authentication in yaz-client. Use the command
1908 * Fix the OID of the Index Data-local "admin" Extended Service from
1909 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1910 the 1000, which indicates a locally-defined OID, was a mistake.
1912 --- 2.0.3 2003/06/20
1914 Fix CCL directive @case handling so that it affects string match for
1915 both CCL keywords and qualifiers.
1917 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1918 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1919 Decoder has been updated with ASN.1 changes as listed in
1920 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1921 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1922 z_IUUpdate, remains unchanged.
1924 ZOOM_record_get may now return a record in a specific character set.
1925 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1926 "from" is the character set of record as returned by target. "to" is
1927 the character set to be returned. If omitted, "to" is UTF-8.
1929 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1931 New ODR utility, odr_getelement, which returns name of element for
1932 which encoding/decoding failed.
1934 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1935 in cases where a required element was omitted.
1937 Bug fix: some MARC8 sequences were not converted.
1939 New ZOOM option "step" which specifies number of records to be
1940 retrieved in one chunk. Used in conjunction with "start" and "count".
1942 SRW support for yaz-client. Use scheme http: to use it, e.g.
1945 yaz-client no longer does (un)intelligent character set conversions
1946 by default. Can be enabled with charset and marc_charset commands.
1948 xmalloc trace fix for 64-bit systems such as DEC alpha.
1950 Solaris 2.6 compile fix.
1952 New function, cql_strerror() translates SRW error codes, as returned
1953 by cql_transform_error(), into human-readable English strings. Used
1954 in yaz-client diagnostics when appropriate.
1956 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1957 converts it into a type-1 query which is sent to the server. This
1958 makes CQL available for use with all Z-servers, as opposed to the tiny
1959 minority that can handle CQL queries themselves.
1961 --- 2.0.2 2003/04/28
1963 New Debian package layout similar to the Redhat Package layout.
1965 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1966 and search result respectively.
1968 --- 2.0.1 2003/04/25
1970 Redhat package is now several packages: libyaz (runtime libraries),
1971 libyaz-devel (development and documentation, and yaz (utility programs).
1972 Package spec file by Morten Bogeskov.
1974 New member 'schema' in struct bend_fetch_rr which the name of requested
1975 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1976 handler MAY set this to reflect the schema of the returned record.
1978 New member 'display_term' in struct scan_entry. GFS now sets member entries
1979 and allocates scan entries to be filled by user scan handler. In previous
1980 version, entries member was allocated by the scan handler. That still works,
1981 but the GFS will ignore member display_term - assuming it was NOT set by
1982 the handler. The fact that the GFS now allocates the entries both allows
1983 for new members and makes a scan handler easier to write.
1985 Fix CQL lex buffer overflow.
1987 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1988 SRU default recordPacking is string.
1990 SRU protocol support for frontend server.
1992 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1994 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1996 Added scan for the ZOOM shell (zoomsh).
2000 * String Identifers for Schemas (Amendment 5).
2001 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2002 Old definition for schema
2003 Odr_oid *schema; /* OPT */
2008 Z_InternationalString *uri;
2009 #define Z_Schema_oid 1
2010 #define Z_Schema_uri 2
2013 * resultCount parameter to Sort Response (Amendment 1).
2014 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2016 Support for SRW 1.0 over HTTP. This is an optional feature and
2017 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2020 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2021 on the same port. SRW SearchRetrieveRequests are mapped
2022 to bend_init,bend_search,bend_fetch,bend_close.
2024 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2026 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2027 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2029 ZOOM connections are SRW based if schem http is used for hostname
2030 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2031 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2033 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2034 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2035 distance=n, order=true/false, relation=le, prox unit=word. If
2036 n is omitted, distance 1 is used.
2038 Fixed problem with C compiler include path in wrong order.
2040 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2041 on Solaris. Patch from Ko van der Sloot.
2043 New MARC decode API. All new functions operate on a yaz_marc_t
2044 handle. The most important new functions are: yaz_marc_create,
2045 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2046 decode and destroy respectively. Decoder can produce formats
2047 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2048 include/yaz/marcdisp.h.
2050 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2051 to UTF-8, UCS-32, wchar_t or Latin-1.
2053 * Prototypes for yaz_iconv_-functions moved to separate header
2054 include/yaz/yaz-iconv.h.
2056 Make a few private functions 'static' in unix.c. This prevents
2057 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2059 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2060 are set when Init Response is received.
2062 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2063 but returns diagnostic set as well.
2065 New function yaz_strerror which is a portable wrapper for
2066 strerror/strerror_r/GetLastMessage.
2068 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2069 is returned for MARC. If type is "oai", then OAI MARC is returned.
2071 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2074 --- 1.9.2 2002/11/26
2076 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2078 Fix bad race conditions on SIGTERM and terminate gracefully in
2081 Move retrieval (data1) module to Zebra since nobody seems to be
2084 Add GRS-1 render for ZOOM using same format as yaz-client.
2086 --- 1.9.1 2002/10/05
2088 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2090 Fix broken ESpec handling in data1 module.
2092 SGML reader parses comments and makes them part of the data1 tree.
2094 Added several type casts so that YAZ compiles as C++ code.
2096 ZOOM didn't handle PDU encoding failures properly.
2098 Added more Bib-1 diagnostics (approved extensions).
2100 GNU configure: better check for iconv.
2102 More portable use of accept, getpeername. Check for socklen_t. Use
2103 int/size_t if socklen_t is not defined.
2107 PQF parser rejects bad queries - including those with extra
2108 characters in them. PQF parser used to silently ignore that.
2109 Cleaner API for PQF added, which allows you to get detailed
2110 error information for bad queries (see yaz/pquery.h).
2112 Fixed bug in ZOOM_record_get for type "database".
2114 Implemented mini iconv library supporting conversions between
2115 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2117 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2119 --- 1.8.9 2002/08/20
2121 Fixed ZOOM C record cache so that preferredRecordSyntax and
2122 elementSetName is used to check for already fetched records.
2124 --- 1.8.8 2002/08/02
2126 Added three members in bend_initrequest structure to facilitate
2127 character set negotiation.
2129 Fixed a bug in frontend server that could cause indefinite
2130 loops under rare conditions.
2132 Revised character set utilities (charneg.h) so that encoding
2133 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2135 For PQF, directive @term <type> sets term type for Scan/Search.
2136 Here <type> is general, string, numeric, null. The term type
2137 is inherited - just like @attr.
2139 New call odr_set_charset that sets character set conversion for
2140 international-strings on a ODR stream. Prototype is:
2141 int odr_set_charset(ODR o, const char *to, const char *from);
2142 The InternationalString is still represented as C string in YAZ
2143 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2144 won't). On the protocol level, you can use any encoding.
2146 Support for UNIX sockets in ZOOM.
2148 Solaris recv sometimes returns errno == ENOENT. It is treated as
2149 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2151 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2152 both client and server. Code by Morten Bogeskov.
2154 --- 1.8.7 2002/05/22
2156 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2157 that they can be used directly from Visual Basic. You must recompile
2158 your windows APP if you're using ZOOM.
2160 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2161 Commands "lang" and "charset" sets language and character set respectively.
2162 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2163 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2165 Attributes from multiple CCL fields may be OR'ed rather than merged
2166 using directive "@field or". Fields are still merged by default -
2167 equivalent to "@field merge".
2169 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2172 Fixed bug in zget for parameter ExtendedServicesResponse.
2176 --- 1.8.6 2002/03/25
2178 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2180 Client displays USR.1:SearchResult-1 (hits per term).
2182 Additional Search Info for search in Generic Frontend Server.
2184 Fixed CCL parsing of "field=s".
2186 WIN32 installer - using the excellent NSIS software from nullsoft.
2188 Fixed CCL parsing of "field = - <number>".
2190 Added function yaz_marc_decode that decodes MARC for line mode
2191 display or XML (similar to that used by JZKit).
2193 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2194 Z39.50. But ISO/ILL was, however.
2196 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2197 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2199 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2200 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2202 --- 1.8.5 2002/02/03
2204 New YAZ client features: Command completion and new commands:
2205 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2206 Code provided by Jacob Poulsen.
2208 New call oid_trav, that visits all registered OIDs via callback.
2210 Function ZOOM_record_get now returns const char pointer rather than
2211 void pointer. It saves a lot of type casts.
2213 For YAZ client, command "auth" now allows you to set authentication
2214 in IdPass style. It is enabled when three tokens are given - order
2215 is user, group and password.
2217 Fix memory leaks in MARC record handling for ZOOM.
2219 New option for YAZ client, -k <kilobytes> that sets
2220 maximum record size. Similar to -k option for generic frontend
2221 server and yaz-ztest.
2223 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2225 Prefix query parser reports "fail" when bad attribute set is given.
2227 Fix in MARC decoder. Proximity logging. Fix for attribute set
2228 in scan handler for server. Patches by Shigeru Ishida.
2230 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2233 Configure option --with-openssl=<dir> now works when a directory is
2234 specified. Patch provided by Morten Bogeskov.
2236 New option for YAZ client, -u <auth>, that sets authentication.
2238 ZOOM fix: error information was sometimes "missing", since error
2239 was cleared/reset too when it shouldn't.
2241 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2243 --- 1.8.4 2002/01/04
2245 Scan for ZOOM API. New object ZOOM_scanset. New functions
2246 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2247 ZOOM_scanset_destroy.
2249 New ZOOM function, ZOOM_connection_last_event, that returns type
2250 of last event (such as "receive data", "send data", "apdu received",
2253 New ZOOM option, schema, that specifies schema for retrieval.
2255 New CCL feature. Qualifiers can be aliases for one or more
2256 other qualifiers (if more than one is given, OR is used).
2258 ZOOM uses named result sets if target supports it.
2260 Two new YAZ client commands: . (dot, which sources a script of YAZ
2261 client commands), and ! (to execute shell command.). Implemented
2264 Working on Debian packages.
2266 --- 1.8.3 2001/11/19
2268 YAZ client enables named result sets only if target supports it.
2270 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2272 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2273 with key="host" to get same result.
2275 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2276 Function Z3950_resultset_record(s) returns references to records
2277 "owned" by resultset. To become owner use Z3950_record_clone.
2279 Function z_ext_record handles Extended Services. Thanks to
2282 --- 1.8.2 2001/11/12
2284 CCL Parser fix: ignore token comma when dealing with and-lists.
2286 Documentation updates for COMSTACK.
2288 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2289 Changed prototype Z3950_records. For some functions, int parameters
2290 were changed to size_t.
2292 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2295 New MARC decode/display function, marc_display_exl, which properly rejects
2296 non-ISO2709 records. YAZ client uses it.
2298 --- 1.8.1 2001/10/29
2300 Fix bug: local attribute set wasn't set correctly in PQF strings.
2304 * Old Z39.50 codecs no longer supported.
2306 Added ZOOM C binding. See http://zoom.z3950.org/
2308 Renamed states for COMSTACKs to avoid confusion with events.
2310 Implemented cs_look and proper cs_rcvconnect.
2312 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2314 Configure detects POSIX threads on OpenBSD.
2316 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2317 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2319 When error is returned from present handler, non-surrogate diagnostic
2320 is returned in present response (and fetch handler is no longer called).
2322 * Minor adjustments to pquery parser (PQF). Token characters may be
2323 escaped by using backslash (C-style).
2325 PQF parser allows string attribute values to be specified. For @attr,
2326 non-numeric characters after the equal-sign are treated as strings
2327 (e.g. @attr 9=title).
2329 CCL trunction character may be defined (@truncation in file)
2331 * function zget_ExtendedServicesRequest sets waitAction to
2332 waitIfPossible (was wait).
2334 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2337 CCL operator names may be set in field definition files (CCL_bibset).
2338 See ccl/bib1 for an example.
2340 Fixes in ASN.1 compiler for C++ compatibility.
2342 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2343 and "op_or" to avoid conflict with C++.
2345 Fixed problem with GNU readline detection on Redhat 7.0.
2347 Added step-size for Scan backend handler.
2349 Fixed bug that made the frontend server crash when no attribute
2350 set was specified for scan.
2352 Front-end server automatically switches to original working directory
2353 when installed as an NT service. Previously -w had to be specified to
2356 Added extended attributes for retrieval module (data1), so that data1
2357 records carry d1_readXML/SGML attributes. d1_read also supports
2358 null-data rules ( <tag/>)
2360 On UNIX when POSIX threads are available, a separate library libyazthread
2361 is created. Programmers should link with that library and the yaz library
2362 when using threads. The reason for the split was that some applications
2363 on Linux, such as Apache, doesn't work well when using shared objects that
2366 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2367 (or any frontend server) in SSL mode by specifying ssl: followed by
2368 address. Only tested on UNIX.
2370 Added feature for CCL module. Virtual structure s=al or s=ol generates
2371 and-list and or-list respectively instead of phrase search.
2375 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2376 log_mask_str. This was done to avoid name conflicts with other libraries
2377 (such as other PHP extensions).
2379 Added raw OID member for preferred record syntax (request_format_raw)
2380 and returned record syntax (output_format_raw) for backend fetch method.
2382 Config file yaz-config now accepts options so that it returns specific
2383 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2385 Shared library support for UNIX using GNU libtool.
2387 * Modified backend interface. Request/Response struct's replaced by
2388 one read/write C struct. For example bend_fetchrequest and
2389 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2390 Every handler - even search has to be registered in bend_init
2391 handler. This means that the YAZ library no longer refers to
2392 external functions and it makes it possible to make the whole
2393 thing a single DLL/SO.
2395 Added Segment handler for backend server.
2397 Added Zmbol/Zebra administrative functions to YAZ client.
2399 Threaded frontend server on UNIX (when POSIX Threads are available).
2400 Starting the server with option -T enables multi-threading.
2404 Added configure option --enable-comp/disable-comp to control use
2405 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2406 located in sub directory asn.
2408 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2409 in ${exec_prefix}/bin along with the other programs yaz-client and
2412 GNU automake used to maintain makefiles.
2414 Added several OID's.
2416 Changed retrieval module so that we can load records with no abstract
2417 syntax defined. Tagpaths in these records are fully composed of string
2420 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2424 On UNIX, the generated makefile now supports a proper 'make install'.
2425 The prefix can be set via GNU configure to set the install location
2426 (default is /usr/local).
2428 * YAZ programs client and ztest were renamed to yaz-client and
2429 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2430 locations, such as /usr/bin,/usr/local/bin,etc.
2432 * YAZ Header files were moved from include to include/yaz. YAZ Header
2433 files are referred to as include <yaz/log.h> rather than <log.h>.
2434 The YAZ include path (-I ..) is therefore the same as before. Programmers
2435 should update their #include statements or use -Ipath/include/yaz
2436 instead. The main motivation for doing this change is that YAZ header files
2437 can be installed in "standard" locations /usr/include,/usr/local/include
2438 without introducing conflicts, since ALL YAZ header files are stored
2439 in subdirectory yaz (under /usr/include for example).
2441 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2442 rather than project/workspace files. We switched because project files
2443 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2446 Changed name of logging function, logf, to yaz_log, to prevent name
2447 clash with some math-log functions. The YAZ header log.h defines logf
2448 to yaz_log (#define) so there should be no incompatibilities by this
2451 Added bend_start/bend_stop handlers for server. These handler are
2452 called on start/stop of server. For windows they are called whenever
2453 a service is started/stopped.
2455 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2456 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2457 in util/yc.tcl. The auto-generated C code structures are, in a few
2458 cases, incompatible with the old decoders. There are differences in the
2459 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2460 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2461 The preprocessor variable ASN_COMPILED is defined when the compiled
2462 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2463 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2464 wish to use the old encoders/decoders you can specify --disable-yc
2467 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2468 version so that it supports both new - and old version of DB Update
2470 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2471 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2472 change. The name parameter can be set to 0 in which no name is specified
2473 for the construction. The macros odr_implicit and odr_explicit sets name
2474 parameter to zero for the construction involved. New macros
2475 odr_implicit_tag and odr_explicit_tag are similar to the others,
2476 except that a name parameter is added. For programmers' that don't use
2477 ODR they probably only need to change the call to z_APDU and z_External.
2479 Added access control facility by interfacing the TCP wrapper library.
2480 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2481 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2482 name of the daemon and enables the access control as specified in
2483 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2485 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2486 den Dool <H.M.vdnDool@kub.nl>.
2488 Added reference ID parameter to most functions in server API - refer
2489 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2491 Changed name of ccl library to libccl.a (was ccl.a).
2493 Fixed bug in decoder for Explain (Category TargetInfo).
2495 Added support for GNU readline in client. Thanks to Jacob Poulsen
2496 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2498 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2499 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2500 IMPLEMENTATION! This change was made to the development version before
2501 the ZIG decided to retract the amendment. If any users MUST be
2502 compatible with the original Update definition, PLEASE CONTACT US, and
2503 we will include a separate definition corresponding to the old Update
2504 ES. Note that because of the change to the ASN.1 of the
2505 TaskPackageRecordStructure we cannot define a single structure that
2506 will support both versions.
2508 * Added const modifier to buffer parameter for some ODR/BER encoding
2509 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2510 completeWAIS, odr_dumpBER.
2512 Fixed bug in client.c which caused a crash when a scanResponse didn't
2513 contain positionOfTerm.
2515 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2516 * will cause an error in a client if a non-YAZ target sends both a
2517 * list of Scan entries and non-surrogate diagnostics.
2519 Retrieval module enhancements. Tag sets may be typed in the reference
2520 to it. From the .abs-file the "tagset" directive takes a third optional
2521 integer type for the tag set referenced. From a .tag-file the "include"
2522 directive takes a third optional type as well. The old "type" directive
2523 in the tag set itself is still recognized but acts as the default type
2526 Backend interface change. Individual Scan terms returned from bend_scan
2527 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2528 in include/backend.h.
2530 Retrieval module enhancements. Multiple tag sets and attribute sets may
2531 be specified in abstract syntax specs. Revised the error/warning for
2532 logging messages reported by the retrieval module when reading the
2535 Object Identifier system (oid_..) changed. The API is backwards
2536 compatible but the oid-routines now allocates new OID's when needed.
2537 Raw OID's may be specified in oid_getvalbyname.
2539 YAZ now uses GNU configure to generate Makefile(s).
2541 * Minor changes in some of the member names of DeleteResultSetRequest and
2542 DeleteResultSetResponse. See include/proto.h.
2544 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2545 and added member 'languages' in TargetInfo (which was missing).
2547 Changed the way attribute sets are handled in the retrieval
2548 module. These are now cached, just like the abstract syntaxes
2551 Changed YAZ so that it links with compiled ASN.1.
2553 Added Explain-schema definitions and mapping routines. The following
2554 Explain categories have been implemented: AttributeDetails,
2555 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2557 Fixed minor bug in Windows version of Server Library.
2559 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2561 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2563 Added EXTERNAL: UNIverse Resource Report (non-standard).
2565 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2566 ENUMERATED and SET OF.
2568 * Added 'const' to some of the char pointer arguments for the
2569 functions, data1_read_node, data1_getelementbytagname,
2570 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2573 Fixed bug in data1_insert_taggeddata - the last_child member of
2574 parent wasn't initialised.
2576 * Changed data1_read_record and data1_read_node so that the supplied
2577 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2578 doesn't refer to any parts of the "SGML"-buffer.
2580 Fixed bug in server library (Windows version of statserv_remove).
2582 * Changed code so that it compiles as C++. The type definition
2583 of Odr_fun which is a member of Odr_arm was changed. The result is,
2584 that an explicit typecast is needed for the fun pointer when
2585 using Odr_arm - as in:
2586 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2588 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2590 Implemented the new structured date and time definition as approved
2591 by the ZIG. Added schemaId element to the specificTag in Espec-1
2592 (also approved at the last ZIG). Thanks to RVDM.
2594 Added some Object identifiers (RVDM).
2596 Changed the Update Extended Service (RVDM).
2598 Added command "refid" to client which specifies referenceId for
2599 the following requests.
2601 Implemented extended service handling for server. See ztest.c
2602 for an example as well as backend.h. New handlers are registerd
2603 in the Init handler.
2605 * Changed interface for sort in server.
2607 Added new members to statserv_options_block. It allows a server
2608 to read options from another source than just the command line. Thanks
2609 to Charles Woodfield.
2611 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2612 renamed to zboolean. Some C++ compilers complained about the name.
2614 Minor changes to gils.abs. Added index 's' (sort) on title
2615 and date/time-last-modified.
2617 --- 1.4pl2 1998/1/30
2619 Fixed bug in server library regarding inetd mode (-i). This bug
2620 was introduced by release 1.4.
2622 --- 1.4pl1 1998/1/29
2624 Added sort facility in client and backend server interface.
2626 Fixed problem with dependencies in Makefile(s).
2628 Fixed bugs for encoders/decoders of extended services and
2631 Implemented sub-tree feature for schemas. Sub-trees are
2632 referenced in *.abs-files. See explain.abs for an example
2633 of the use of this feature.
2635 Modified bib1.att; local attributes for ANY didn't include
2636 ANY itself (only affects use of the retrieval module).
2638 Fixed bug in plain SGML reader in function data1_read_node:
2639 tags with prefix "var" was incorrectly interpreted as variants.
2641 Added feature "sub-schemas" to enable references to - and definitions
2642 of - group of elements.
2644 * Removed member parent from type data1_element (in data1.h).
2646 Implemented function odr_nullval() that returns the value of
2649 * Removed member num_children from data1_node (in data1.h).
2651 Made NT service interface part of the server library. The
2652 function statserv_main uses the NT service when required and
2653 calls the statserv_start / statserv_close routines.
2655 Routine zget_SearchRequest and zget_PresentRequest fills
2656 resultSetName/Id member with "default" instead of "Default".
2658 Fixed memory leak in server. Request queue member wasn't freed.
2660 Fixed nmem_exit so that memory is freed.
2664 Revised the CCL parser utility to be thread safe.
2666 Added function, oid_ent_to_oid, to replace the function
2667 oid_getoidbyent, which is not thread safe.
2669 * Added nmem_init and nmem_exit to initialize and release
2670 NMEM resources. Function nmem_init should be called once in the
2671 initial thread before NMEM/ODR is used. statserv.c and client.c
2672 have been changed accordingly. The change was necessary to make
2673 NMEM thread safe. The NMEM memory pool is shared amongst threads
2674 in a process. Unix-based applications will still work fine without
2677 Added NT Services interface for the the Z39.50 (statserv) Server.
2678 Refer to the ztest.c source on the usage.
2680 Windows 95/NT port using MSVC5.0. Project files are included in the
2683 * Defined new 'global' handle for the retrieval (data1) system. The
2684 new handled, data1_handle, describes the state of the data1 system.
2685 This handle is passed as first argument to virtually all
2686 data1 related routines. The functions data1_create and data1_destroy
2687 creates and destroys a data1 handle respectively.
2689 Added ODR encode stream member to all backend request structures
2690 init, search, scan etc. This stream should be used to allocate all
2691 memory used for the response when thread safe operation is needed.
2693 Changed the comstack utility, cs_addstr, to be thread safe. The
2694 returned hostname string returned by the function is now part the
2697 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2698 function. The cs_straddr takes a COMSTACK handle as argument, so this
2699 function must be used after cs_create and before bind/connect.
2700 This function is thread safe.
2702 Moved test server to 'ztest' directory - generic server code still
2703 in 'server' directory.
2705 Made prefix query (pquery.c) utility thread safe.
2707 Added new function modifier YAZ_EXPORT to 'export' public DLL
2708 functions when using windows (see include/yconfig.h).
2710 Added definitions to the OID database (util/oid.c) (RVDM).
2712 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2714 Added call to ccl_rpn_delete in client program.
2716 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2717 release of RPN structure.
2719 Added support for C++, headers uses extern "C" for public definitions.
2720 With input from RVDM.
2722 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2723 Thanks to Ronald van der Meer (RVDM).
2725 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2727 Added support for private extensions to the OID database
2728 (oid_setprivateoids()). Thanks to RVDM.
2730 Added optional, physical ANY (key replication)
2732 Fixed null-reference problem in GRS-1 output filter.
2734 Proximity operator added to Prefix Query Format (PQF).
2736 In test client command "base" accepts multiple databases.
2738 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2742 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2744 Smallish bug-fixes in the new encoders/decoders (explain).
2746 Bug fixed in DeleteRequest.
2748 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2750 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2752 Added SOIF syntax (using private OID for now) to retrieval module and client.
2754 Added Update extended service.
2756 Added SearchResult-1 additional info structure.
2758 Added optional CCL (ISO8777) interpreter as separate module. Available
2761 --- 1.2 1996/6/10 (1st anniversary release)
2763 Added Summary record syntax. Lightly tested.
2765 Added OPAC record syntax. Untested.
2767 Added ResourceReport service encoders/decoders. Untested.
2769 Fixed bug in z_Unit - wrong tagging on unitSystem.
2771 Fixed bug in the DiagRecs decoder.
2773 Added options for max PDU size and session timeout to frontend-server.
2775 Added documentation of query-language parsers and other supporting utilities.
2777 [frontend-server] Added Attribute set to the bend_scanrequest API.
2779 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2780 surrogate diagnostics were generated.
2782 [retrieval] Allow multiple local values for attribute.
2784 [retrieval] Allow multiple attributes per element in .abs files. index type.
2786 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2788 --- 1.1pl2 1996/4/10
2790 Minor changes, mostly specific to Zebra's requirements (retrieval)
2794 Repaired bug in frontend server when running multiple listening
2795 endpoints in dynamic mode.
2797 z_External() now won't break if a known, ASN.1 value comes encapsulated
2798 in an octet-string. The value will pass through unmodified in an Odr_oct.
2800 Added a bit of code to the demo client to decode & display
2801 ASN.1-structured records represented in the octet-aligned branch of
2802 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2804 Added z_ext_getentbyref() to the ASN module. Doc updated.
2806 * Completed the SCAN definition in the ASN module. This may break SCAN
2807 code based on older YAZ-versions at compile-time. The fix is easy -
2810 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2811 under the SCAN definition. Remember to initialize this, server-people.
2813 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2814 that this does not extend to ODR and ASN.
2816 Comstack allows insertion of established socket (primarily for
2817 inetd-operation of servers). Doc updated.
2819 Front-end server can now start from the inetd in TCP mode. Doc
2822 --- 1.0pl4 1996/1/24
2826 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2827 the rank and record number.
2829 Adjustments to the frontend server.
2831 Fixed diagnostic BER dumper. It ignored the file argument.
2835 Various changes to retrieval module.
2837 Changed the union discriminators of the protocol files from enums to
2838 ints paired with #defines.
2840 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2843 *Changed operator in the RPN structure to 'roperator', again to avoid a
2846 Fixed problems in Explain decoders/encoders.
2848 --- 1.0pl2 1995/12/6
2850 Memory bug in log module fixed.
2852 --- 1.0pl1 1995/12/5
2854 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2856 Bug in Explain DatabaseInfo module fixed.
2858 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2862 The shift to v1.0 signals that we now consider the *core* functionality
2863 of YAZ reasonably stable (the core being more or less equivalent to
2864 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2865 tested (Explain not at all - though that will happen soonish).
2867 Minor changes to code to support Windows port.
2869 Various minor changes after we're getting to use GRS-1 & co. more.
2871 Added Espec-1 format.
2873 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2874 of the protocol and it cannot be selected when encoding (maps into 'string'
2875 when decoding). Needed to talk to some servers.
2877 Demo client can request simple element set names.
2879 Added Diagnostic Format encoders/decoders.
2881 Added simple Close handling to frontend server (no hooks for resource
2882 reporting yet), and demonstration client.
2884 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2886 --- 1.0b3 1995/08/24
2888 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2889 handled incorrectly when records were requested in the searchResponse. This
2890 will only affect you if you use the frontend-server.
2892 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2893 Test-client will ask for and print GRS1. Ztest will return dummy records
2896 Added Explain encoders/decoders to the service-level API. Untested.
2898 Added Extended Services: Item Order encoders and decoders to the Service-
2899 level API. Untested. We could use a recent copy of the pertinent bits
2900 of the ILL protocol to add those bits.
2902 Added diagnostic format 1 encoders/decoders to the service-level API.
2905 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2906 odr_cons.c, which causes a more correct output.
2908 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2909 was always set to 0 when no records were requested in the searchRequest.
2911 * Added better external-handling. This shouldn't harm old code that
2912 *encodes* externals. It can break code that looks for a
2913 'single-ASN1-type' representation, since those types that are known
2914 are now decoded immediately. Look at the SUTRS sample code in
2915 seshigh.c and client.c. Documentation updated.
2917 Handling of structured records in bend_fetchresponse. Length -1 marks
2918 structured record, type is deduced from format field.
2920 --- 1.0b2 1995/06/27
2921 Fairly quick maintenance release to add SUTRS support.
2923 Fixed handling of SUTRS records in the demonstration client.
2925 * Added format field to the bend_fetchrequest and bend_fetchresponce
2926 structures of the backend API (frontend server). When the record is
2927 returned, the value of the format field is mapped to an OID. The
2928 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2929 of the record. The special value VAL_NONE in the bend_request means
2930 that no specific format was requested by the client. Documentation
2931 updated accordingly. Test server (ztest) will return a fixed dummy
2932 SUTRS record if your client requests SUTRS.
2934 Documentation updated accordingly.
2936 You can now set external libraries and RANLIB support in the top-level
2940 First public release.
