3 zoom: throw diagnostic for invalid value for option "sru". Before a
4 bad SRU request was sent.
6 Adding new utility wrbuf_vp_puts.
8 Add cclxmlconfig.obj to win/makefile. It was missing completely.
12 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
13 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
14 redirect was used at the same time.
16 MARC line mode decoding: be less picky about length given - first
17 5 digits of header that is.
19 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
21 Changes to decoding of SRU records: a record with recordPacking=xml is
22 modified with a new root element <yaz_record> if the recordData contains
23 multiple children elements. This is to make the record XML parseable
26 RPN to SOLR conversion: encode special characters.
28 Generic Frontend Server: fix uinitialized member, stepSize.
32 Fix a bug in SRU decoding of records.. The database records stored
33 had un-initialized memory, but it would only be seen with yaz_record_render
36 Fix a bug in ccl_qual_dup introduced in 4.2.3.
40 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
44 Add new utilities to convert from CQL to CCL . These utilities have
45 prefix cql_to_ccl defined in cql.h.
47 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
48 lead to memory heap corruptions when ICU utilities were in use.
52 Make compilation work without Libxml2.
54 yaz-client: remove redundant blanks in display of searchResult-1 term
59 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
60 resulting CQL node (tree) in a new node CQL_NODE_SORT.
62 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
63 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
64 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
65 Note that the CQL sortby spec is only converted when the GFS is already
66 converting from CQL to RPN (cql2rpn element).
68 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
69 specify whether to collapse delimitors or not. The existing nmem_strsplit
70 do collapse (collapse parameter = 1).
72 Windows installer: For NSIS, set InstallDir depending on x86/x64.
74 Rename internal func yaz_use_attribute_create. While non-static, this
75 function is not declared in a public header.
79 Add -lCrun when linking with ICU on Solaris.
81 More quicks character set conversions for OPAC records.
85 fix problem with record_render: records were converted (character set
86 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
90 SRU: add methods for handling DADS SRU-proxy facets.
92 Separate OPAC record character set for ZOOM_record. yaz_record_render
93 allows a character set given as charset=from/opacfrom,to where 'from' is
94 the character set of a bibliographic record, 'opacfrom' is character set
95 of OPAC record and 'to' is the target character set.
99 yaz-client: show may XML format records. Command show followed by 'format'
100 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
103 src/stemmer.c: Avoid using unnamed union. It is not supported by some
106 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
109 Update yaz.spec to operate on both SLES11 / Centos 5.5.
111 RPM: Release includes 'indexdata' name. Use indexdata in release name so
112 this package can be distinguished from other vendors.
114 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
115 as determined by configure
117 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
119 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
120 returns no error and no record, the present request is considered
121 partial (only a subset of the records could be returned by backend), and
122 so it is appropriate to set Present Status to partial-4.
126 Move yaz-config man pages to section 1.
128 More documentation about SOLR.
130 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
131 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
132 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
133 peers on some Linux systems. However, in general that does not work
134 so YAZ can not rely on that to work. Debian changed behavior in this
135 respect from Debian lenny to Debian squeeze (still testing as of Oct
137 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
139 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
143 Fix yaz-config output: echo_source not set correctly by configure.
147 SOLR WebService support for yaz-client and ZOOM.
149 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
151 --- 4.0.12 2010/08/17
153 Z39.50 facet support. Facet specifications are passed for search in
154 other-information with ASN.1 as defined in facet.asn and OID
155 .10.1000.81.5 . Facets are expressed as an Attribute list as known
156 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
157 3 is limit (number of entries to get in response). yaz-ztest returns
158 dummy facets if a client asks for them.
160 --- 4.0.11 2010/07/09
162 CCL fixes: bug 2895 and bug 3539.
164 GR1-display: add comma in display - was removed by mistake in
167 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
169 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
171 --- 4.0.10 2010/06/18
173 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
174 result set from a connection. The result set will be on its own
175 thereafter; no operations on it will perform retrievals from a target.
176 Only cached copies are returned.
178 ZOOM C:fix case for HTTP servers responding with Connection:close.
179 Ensure that if there is a current task it is resumed (like fetching
180 more records in a result set) . Bug #3484.
182 PQF parser: use odr_atoi for Odr_int (not atoi)
184 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
185 values that contain any non-digits are treated as string attributes
186 (previously decoding only checked for leading character ([0-9]). PQF
187 encoding: attribute string values are not surrounded by double-quotes.
191 New utility for managing threads - thread_create.h.
193 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
194 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
195 but YAZ' implementation do.
197 Fixes for yaz_cond-functions on Windows 7.
199 DLL export more symbols.
201 zoomsh: show record do NOT render opac.
203 Remove *.la files from Debian and RPM packages.
207 Debian package libyaz-dev depends on libgnutls-dev again (was
208 removed in YAZ 4.0.6, but due to Libtool it is still needed
209 even though yaz-config do not list libgnutls libs).
211 ZOOM: Use only one WRBUF for returning string results for
212 ZOOM_resultset. Reduces memory usage for ZOOM in general.
214 ZOOM: ZOOM_connection do not use a shared pointer to
215 ZOOM_resultset after ZOOM_resultset is destructed by
216 user. Reverts to YAZ 4.0.4 behavior.
220 record-conv: fix problem with at least one XSL conversion -
221 due to probably incorrect usage of XML XSL documents.
225 Fix yaz-config for static mode and the use of SSL (gnutls).
229 Forward decl timeval struct in mutex.h and gettimeofday.h.
231 yaz-config: fix 'static' mode linking.
235 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
236 are wrappers for pthreads or Windows. For Windows these are put in
237 a separate DLL: yaz_cond4.
239 libyaz.la (whole source) is compiled with thread. If thread support
240 is enabled enabled, all source of YAZ is compiled with treading support.
241 This allows core utilities such as yaz_log to use thread facilities.
242 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
243 thread utilities. This commit moves mutex utilities (mutex.c) from
244 libyaz_server.la to libyaz.la.
246 yaz-json-parse displays leading text until error.
250 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
251 patch from Giannis Kosmas.
253 SRU: no longer URL encode SRU database. The URL for an SRU server is
254 a URL and such is alreeady encoded - at least when given with leading
255 http:// or https://. This reverts behavior to YAZ 3.0.50.
257 Support for new MARC XML notation TurboMARC which like MARCXML is a
258 complete representation of MARC/ISO2709.. This one, however, is more
259 compact and allows for faster processing with XSLT. TurboMARC can be
260 used in the marcdisp.h API, from the yaz-marcdump utility and from
263 yaz-ztest can be configured - via the database - to perform certain
264 delays when it performs operations search, present and single record
265 fetch. This allows testers to make yaz-ztest act as a real or even slow
266 Z39.50 server. Refer to the yaz-ztest man pages for details.
270 wrbuf_destroy allows NULL WRBUF passed to it.
272 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
274 Add ZOOM_connection_close.
276 No fixed size buffers for ZOOM shell - bug #3257.
278 tstodr: make it work on s390 platform.
280 New icu iterator-functions. The new icu_iter-functions makes it possible
281 to use ICU chains from many threads.
283 yaz-client: better syntax check for show command.
287 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
290 New simple local-file XML include facility which allows file glob-patterns.
291 Refer to yaz/xml_include.h.
293 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
296 ZOOM_record_get supports new parameter "format" which makes it format XML
299 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
300 JSONText in ECMA-262) is JSONValue, not JSONObject.
304 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
305 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
307 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
308 POSIX/Unix builds .so with major version 4.
310 Remove old LOG_-defines from log.h. They have been obsolete and
311 undefined by default for the last 5 years.
313 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
315 GFS: Remove socket (int *fd) from search_rr handler. The socket
316 descriptor ptr is a facility that allowed a search handler to supply
317 a socket which would serve as a callback - when search was complete.
318 This facility has now been in use for years.
320 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
321 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
322 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
323 returns 'const char *' rather than 'char *. The returned string is
324 read-only and should not be modified by applications. COMSTACK cs_close is
325 now a void function - it no longer returns int. No applications check for
326 the value and the implementations has always returned 0.
328 ZOOM: use size_t for scan hit counts and str size. Functions
329 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
330 occ (hit count) and len (string length) are now of type size_t pointer
331 rather than int pointer. This is to be able to represent large hit counts
332 and to also just to use the proper type for string length (strlen result).
334 New JSON parser. Refer to include/yaz/json.h .
336 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
337 Used to be int in some cases. Many wrbuf_-functions used to return an int
338 indicating some length.. These return values were never used. And so they
341 ODR: odr_malloc, odr_total now takes size_t for size.
343 clone_z_type: fix leak; occurred for encoding failures.
345 --- 3.0.52 2009/12/03
347 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
348 bug was introduced in 3.0.51.
350 --- 3.0.51 2009/12/02
352 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
354 tcpip comstack: fix leak for getaddrinfo.
356 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
357 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
358 Decoding of SRU "path" database is performed by private function
359 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
360 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
362 yaz-client: honor base command for SRU. Change when database setting
363 is applied for SRU and ensure it is kept when a connection is reset.
364 Change also the way errors are displayed or SRU (decoding of packages).
366 --- 3.0.50 2009/11/02
368 Add support for extra request / response data for SRU codecs and GFS.
369 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
370 for extra data response buffer and length. For the GFS, both request
371 and response data (XML) is carried in extra_args and extra_response_data
372 for the search handler. Patch by Ko van der Sloot.
374 ZOOM: For queries that cannot be converted to the specified rpnCharset,
375 ZOOM now returns a diagnostic on the client-side ('invalid query' /
376 10010). This fixes bug #2113.
378 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
379 cmdfile included a 'quit' command that would result in a memory violation.
381 --- 3.0.49 2009/10/01
383 Make a number of functions defined in xmlquery.c static. These have
384 never been declared in a public header file (yaz/xmlquery.h) and was
385 made public by mistake.
387 Improve speed of character conversions (iconv utilities). This makes
388 conversions from MARC-8 faster.
390 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
391 unless type desired is "raw". This will prevent type "xml" from
392 returning ISO2709 .. Which obviously can not be XML parsed.
394 Fix memory leak in ZOOM that would occur if option apdulog was used
395 on a re-used connection.
397 Frontend server logs HTTP requests.
399 Frontend server now sends Z39.50 close when it times out (sesssion has
400 been idle for too long). Versions 2.0.30 and earlier also sent close.
401 But due to a mistake this was disabled in all versions after that, i.e.
402 the server would just close the socket immediately.
404 yaz-client emits a better message when receiving an unrecognised
405 userInformationField.
407 Skip zero-length subfields when decoding ISO2709. This rare case happens
408 if a record has two FS characters in a sequence. Without this patch
409 there would be a reference beyond char array in using_code_len fragments
412 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
414 --- 3.0.48 2009/08/28
416 The show command offered by the zoomsh command now takes a 3d optional
417 parameter type which is what is passed to ZOOM_record. If the type
418 argument is omitted, "render" is used.
420 RPN to CQL conv may use USE string attributes (bug #2978).
422 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
424 --- 3.0.47 2009/07/08
426 Function yaz_xml2query allows a diagnostic element in the PQF XML
427 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
428 code and additional info respectively.
430 The BER BOOLEAN is now the integral type Odr_bool which still happens
431 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
432 typedef'd to Odr_int. This is still an integral 'int', but it may be
433 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
434 ASN-1 compiler as well as programs has been updated to use the new types.
436 --- 3.0.46 2009/06/08
438 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
439 only the bibliographic record was rendered. For type=opac, an OPAC
440 record is only returned if it is present.
442 iconv: small fix for encoding of advancegreek.
444 yaz-client: avoid double display of SRU/SRW records (bug #2798).
446 yaz-client: option auto_reconnect=on really reconnects.
448 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
450 server: avoid null ptr ref for for yaz_poll errors.
452 build: fix RPM build for RHEL 5.3.
454 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
456 --- 3.0.45 2009/03/31
458 Fixed bug #2709: TCP connect returns Invalid argument.
460 Fixed compilation for mingw.
462 Honor charset for raw records (ZOOM_record_get).
464 Fixed use of errno for threaded mode that was seen on Solaris 10.
466 Fixed argument passing with blanks in value for Windows Service.
468 Disable YAZ' own log rotate by default (no 1 GB limit).
469 The variable l_max_size which specifies the log file limit is set to 0
470 (DISABLED): This is due to the fact that YAZ is most often deployed using
471 logrotate. Also YAZ can not perform log rotate because of unsufficient
472 permissions (setuid).
474 --- 3.0.44 2009/02/17
476 List supported encodings in man page for yaz-iconv.
478 Fixed missing SSL libs for --libs output
480 Re-established OID record syntax application-xml. Nobody should use it
481 but we don't want to change soname because of this symbol being absent.
483 --- 3.0.42 2009/02/02
485 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
487 Added member named_result_sets for init handler struct for the GFS. This
488 allows a server to disable named result sets.
490 Removed OID record syntax application-xml.
492 Added support for rule-based transliterator for ICU wrapper of YAZ.
494 Fixed bug #1902: yaz-icu XML output.
496 Make YAZ checks Emacs friendly.
498 BITSTRING value shows value. Bug #2346.
500 ISO2709 decoding: skip control characters from indicator data.
502 Omit sort key by default in yaz-icu's output.
504 Allow combined single char options (again) for YAZ' options function.
506 Utility yaz-marcdump got option to display YAZ version (-V).
508 Allow YAZ to use ICU 3.4.
510 Added new ICU test case which illustrates removal of diacritics.
512 --- 3.0.41 2008/12/29
514 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
516 --- 3.0.40 2008/12/29
518 For configure, using option --without-xml2 also disables Libxslt/Libexslt
521 Fixed bug #2352: yaz-marcdump crashes for certain record.
523 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
525 Added support for Danmarc2 to UTF-8 conversion.
527 Added support for ISO5426 to UTF-8 conversion.
529 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
530 implementation version.
532 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
534 --- 3.0.38 2008/11/10
536 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
537 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
539 ZOOM C now interprets databaseName option for ZOOM connection as path
542 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
544 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
546 Dummy Libxml2 types no longer defined in headers of YAZ'.
548 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
551 --- 3.0.36 2008/09/26
553 Various ODR chapter fixes.
555 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
557 Added missing source for Windows compilation, mutex.c.
559 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
561 For SRU connections in ZOOM all records up to "count" are now fetched.
563 Fixed crash in generic frontend server (and yaz-ztest) which occurred
564 in Windows due to bad error handling for Libxml2.
566 Added facility for sending arbitrary records (ASN.1 any) using
567 ZOOM C's Extended service update. Patch by Sam Reynolds.
569 New options for ZOOM C's connection, logapdu which makes ZOOM log
572 --- 3.0.34 2008/06/18
574 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
576 --- 3.0.32 2008/06/12
578 Fixed memory violation that could occur when decoding UTF-8. This bug
579 was only present in 3.0.30 of YAZ.
581 --- 3.0.30 2008/06/06
583 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
584 GNU TLS is used by default (if found).
586 yaz-ztest returns OPAC records if a client asks for OPAC.
588 Improved speed of MARC-8 encoding.
590 Added support for lossy and loss-less MARC-8 encoding.
592 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
594 Added new Windows Service wrapper (sc).
596 yaz-client's itemorder command may now send a file.
598 Fixed yaz-marcdump to allow the use of NS prefix for record element.
600 Added new function yaz_log_xml_errors.
602 Allow (but warn) unknown XML attributes in MARCXML parsing.
604 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
606 The UTF-8 to MARC-8 conversion now uses a different set of characters
607 for Greek symbols. Bug #2120.
609 --- 3.0.26 2008/02/21
611 Added yaz_daemon (daemon.h).
613 Fixed bug #2068: pkg-config trouble
615 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
617 --- 3.0.24 2008/01/28
619 Document --with-xml2 option.
621 Added OPAC XML XSD (etc/opacxml.xsd).
623 Allow glob mask for name attribute in retrieval element for the
624 generic frontend server's retrieval facility.
626 Changed yaz_poll_poll to return yaz_poll_except for all returned events
627 except POLLIN/POLLOUT.
629 Fixed error handling in cs_listen. Bug #2037.
631 --- 3.0.22 2008/01/20
633 Fixed version in yaz/yaz-version.h.
635 Fixed bug #2027: Crash when closing connection.
637 Changed configure so that ICU support is only enabled if only ICU
638 and Libxml2 is available (because the ICU chain is XML based).
640 --- 3.0.20 2008/01/15
642 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
643 is built. Only this DLL depends on the ICU runtime.
645 yaz-ziffy is no longer part of YAZ. It is distributed separately by
646 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
648 Changed license of CCL module to 'Revised BSD'. After consultation with
649 remaining members of the original EUROPAGATE consortium, we are re-issuing
650 the CCL module without a separate license. The software was developed by
651 Index Data as part of a research project. The special license was included
652 to help feed usage information back to the project consortium to support
653 project evaluation. At this time, the project consortium has long-since
654 disbanded, and the majority of the original principals have retired. At the
655 same time, we have significantly modified the software during the following
656 years, to the point where very practically no original code remains. To
657 simplify re-use of the software, we have contacted those members of the
658 consortium who could be reached, and agreed to re-issue the module as a
659 proper part of the YAZ package.
661 Tcl scripts uses /usr/bin/tclsh as preferred shell.
663 CQL closer to being version 1.2 compliant. CQL also allows free-form
664 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
667 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
668 bug could make Extended services handling crash in the ZOOM layer. This
669 bug was only present in YAZ 3.0.18.
671 --- 3.0.18 2007/12/19
673 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
676 yaz-marcdump reads and writes collection wrapped records.
678 Handle OPAC for record conversion module.
680 Fixes for ICU wrapper.
682 Allow ICU libs to be controlled with --with-icu .
684 --- 3.0.16 2007/11/12
686 Added yaz_poll which is a wrapper for select/poll. When poll is available
687 and non-buggy, it is used, by yaz_poll . This allows more than 1024
688 sockets to be in use.
690 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
691 functionality through an XML based configuration (ICU chain). This system
692 is useful for search facilities such as Pazpar2 and Zebra that needs to
693 perform tokenization of indexed material. The ICU code in a separate
694 library libyaz3_icu.a.
696 Added HTTP tunnel facility for COMSTACK, bug #1752.
697 This is a facility that allows a Web proxy, such as squid, to tunnel
698 Z39.50 traffic. This facility is "transparent" to must applications
699 using YAZ. It's enabled by using pseudo transport connect: followed by
700 the proxy address, followed by command, then follwed by he regular
701 "virtual" addresss. For example,
702 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
704 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
706 --- 3.0.14 2007/09/21
708 Fixed bad memory reference in ZOOM_record - cuased by member not being
709 initialized. This was a problem only in YAZ 3.0.12.
711 Fixed bug in conversion from MARC to XML: Non-XML characters in control
712 fields were not removed.
714 Changed the way C code is generated from codetables.xml. Made a MARC-8
715 conversion trie for each characterSet section rather than codeTable.
716 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
717 of codetables.xml from Larry Dixson, LOC. Bug #1464.
719 --- 3.0.12 2007/09/12
721 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
722 from ZOOM_record_error).
724 ZOOM C function ZOOM_record_get returns record schema for type="schema".
726 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
728 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
730 Better SRW-to-Bib-1 diagnostic mapping.
732 ZOOM C and yaz-client announces SRU version 1.2 by default.
734 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
737 Fixed in yaz_sru_decode to allow other version than 1.1.
739 --- 3.0.10 2007/08/22
741 Added support for SRU scan for ZOOM.
743 Added support for the use of the older versions or Extended Service
744 Update in ZOOM. To faciliate this, an option "updateVersion" may be
745 set to the version , 1=first, 2=second, 3=third. The third version is
746 what ZOOM C has used so far. And that, obviously, is the default.
748 Added support for CCL queries in Z39.50 queries sent to the GFS (and
749 therefore in Zebra and in SimpleServer-based applications). The new
750 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
751 qualifier file used to transform incoming CCL queries into Type-1 RPN,
752 which is passed into the back-end search callback function.
754 Added support for HTTP Basic authentication in clients: the SRU/W
755 codec encodes the username/password elements of the PDU structure
756 appropriately, and these may be set using the "user" and "password"
757 options in ZOOM-C applications (the same options that are used for
758 Z39.50 authentication).
762 Fixed bug #1208: SSL appears to be broken in ZOOM.
764 Fixed bug #1206: Libxml2 include path weirdness.
766 Added oid_name_to_dotstring.
768 Allow elementSetName to be specified for ZOOM C record update.
770 Allow waitAction to be specified for ZOOM C based for Extended Services.
772 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
773 syntax OID. Bug introduced in YAZ 3 series.
775 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
779 Fixed bug #1157: yaz-client does not read .yazclientrc from current
780 directory. yaz-client now reads commands from file given by option -f
781 if specified; then tries to read .yazclientrc in current directory.
782 Failing that, it reads .yazclientrc from user's home directory.
784 Added support for correlationInfo Note and ID for Record Update via
787 Added yaz-client command querycharset which specifies character set for
788 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
789 (termListAndStartPoint).
791 Charset ISO5428:1984 is an alias for ISO5428-1984.
793 Implemented a way to perform scan in a result set using Z39.50. This
794 is achieved by attaching the result set name in the characterInfo
795 (type InternationalString) of OtherInformation in the Scan Request PDU.
796 The result set is identified in the otherinformation by the new OID:
797 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
798 This allows for scan in result set and faceted search . Zebra did some
799 of this in the APT term using attribute type 8 and value being result
800 set. Using the OtherInformation approach for this is cleaner and easier
801 to work with in proxies and the like. This facility can be used in
802 yaz-client using new command setscan which takes a result set as first
803 argument, start position (APT) as second.
805 Changed decoding of SRU XML packed records to deal with servers that
806 have recordData with XML data with multiple root nodes. Also make
807 comparison for recordPacking case insensitive. Again, one server
808 returns "XML" where others return "xml".
810 For SRU responses allow Content-Type application/xml as well as text/xml.
814 Fixed bug in character set conversion of BER strings. Bug introduced
819 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
821 For OID class, use oid_class consistently.
823 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
826 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
827 character set for bibliographic information interchange". By Giannis Kosmas.
829 Added documentation on new OID API.
833 Changes to generic frontend server interface: added new member
834 'query_charset' for bend_initrequest structure. A backend init handler
835 should set this member to its native character set for query terms.
836 When defined, the frontend server logic will announce this character set
837 to a client if the negotiationModel bit is set by the client. All server
838 implementors are encouraged to specify this. If a backend server does not
839 specify this a warning is issued using yaz_log(YLOG_WARN,..).
841 Added CCL utility to remove terms (stop words) from resulting RPN
842 tree. This is handled by functions with prefix ccl_stop_words_ .
844 New ZOOM C option, "rpnCharset", which allows client-side conversion of
845 terms in RPN queries.
847 Clean-up the CCL API. Moved some internal structures from ccl.h to
848 private header cclp.h. Changed ccl_parser_create so that a Bibset must
849 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
850 This is replaced by ccl_parser_find_str which takes a string instead.
852 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
853 libyaz.la is the core of YAZ except the generic frontend server and
854 does not depend on POSIX threads anymore. libyaz_server.la is the
855 generic frontend server facilities and uses POSIX thread functionality
856 if available. The libyaz.la no longer depends on POSIX threads because
857 the number of global structures is limited. NMEM no longer re-uses blocks
858 between threads ; it simply free's memory immediately but allocates in
859 "large" chunks as usual. We don't expect any performance penalties
860 because of this. The yaz_log system is still using a global log_level so
861 caution must be taken when modifying it with yaz_log_init_.. +
862 yaz_log_mask_str. This, however, should not cause any trouble because
863 these functions are called during initialization of application code
864 anyway. `yaz-config --libs server` returns libs for server applications;
865 `yaz-config --libs` returns libs for non-server applications.
867 New OID database - with public definitions in oid_db.h. Removed old OID
868 database including the head oid.h and definitions such as enum oid_value
869 and struct oident. The new OID database uses the same string names as
870 before but the 'protocol' is gone. There are now only two representations
871 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
872 converts from string to OID; functions with prefix yaz_oid_to_string
873 converts the other way.
875 Change to emit_term() in CQL-to-PQF query translation: when a term has
876 the /regexp relation modifier, do not process it for leading and
877 trailing "^" and "*", which have quite different meanings in regular
880 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
881 write handlers no longer carries a 'last' parameter. This will make
882 yaz_iconv flush "less" characters. A flush is performed by call to
883 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
885 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
886 removed, because function yaz_query_to_wrbuf does the same.
888 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
889 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
891 Deprecated MARC utility functions removed.
893 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
896 Branch split: YAZ_2_1_55_branch
898 --- 2.1.54 2007/03/16
900 Fix to ZOOM-C so that transparent reconnection is properly handled on
901 connections that are in asynchronous mode.
903 Fixed compilation on OpenBSD 4.0.
905 Large strings in GRS-1 records are now properly displayed in yaz-client.
907 Added character conversion support for "advancegreek"; based on patch from
910 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
911 sequence is met. Before the error was not set so it would be unknown.
913 Adjust yaz-marcdump MARC reader so that it skips until record separator
916 --- 2.1.52 2007/03/07
918 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
919 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
920 fd_set structure used as a bitmask for the FDs to be selected on.
922 Using ACX_PTHREAD macro to check for POSIX threads.
924 Fixed have-vsnprintf check.
926 --- 2.1.50 2007/02/23
928 Fixes for configure on BSD. Bug #900.
930 Added snprintf/vsnprintf wrappers for systems that don't have
931 limits (heavens forbid).
933 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
934 created before all previous tasks were completed and removed from the
935 task queue, the new task could be removed by a mistake.
937 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
939 Implemented pass-through CQL-to-PQF conversions. Bug #861.
941 Fixed bug #832: Problem with MARC/charset in yaz-client.
943 Fixed bug #668: save command line history for yaz-client.
945 Fixed bug #830: pkg-config support.
947 --- 2.1.48 2007/01/23
949 Extended ZOOM result set options with two options that may be read by
950 a client: resultSetStatus and presentStatus with values as specified for
952 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
954 Fixed bug #827: Using SSL fails on Debian etch.
956 Fixed bug #826: Weird looking chars for set of MARC records.
958 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
959 that is treated as an ItemOrder with itemRequest being an XML document
960 external. The value of "doc" is the content.
962 Extended the GFS search facility. New member of bend_search_rr
963 'estimated_hit_count' signals that hits is known to be an estmate
964 (higher or lower than real hit count). New member 'partial_resultset'
965 signals that the search was partial (hit count is lower or equal than
966 real hit count). For Z39.50, the information is stored in resultSetStatus
967 member of SearchResponse APDU. For SRU, the information is signalled
968 via SRU diagnostic 59: "Result set created with valid partial results
971 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
973 --- 2.1.46 2007/01/13
975 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
977 Added ZOOM_connection_peek_event.
979 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
980 the following new functions:
981 ZOOM_event_nonblock, ZOOM_connection_process,
982 ZOOM_connection_get_{socket,mask,timeout},
983 ZOOM_connection_fire_event_{timeout,socket}.
984 The existing blocking event handler, ZOOM_event, is a wrapper for the
985 + blocking ZOOM_event_sys_{poll,select}.
987 Implemented function ccl_xml_config which parses XML version of CCL
988 configuration (bug #798).
990 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
992 Added timings utility (yaz/timing.h)
994 --- 2.1.44 2007/01/03
996 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
999 Fixed bug #779: Rotation of apdu.log fails.
1001 Fixed for character set conversions:
1002 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1003 Honor G1 set in MARC-8 decoding.
1005 --- 2.1.42 2006/12/17
1007 Fixed bug #775: char conversion does not handle Alternative UTF-8
1010 Implemented function yaz_marc_read_line which parses MARC line format
1011 records. There is a wealth of formats out there. So far, this function
1012 reads line records produced by yaz_marc_write_line.
1014 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1015 more generic and easier to remember(!) options: -i format and -o format
1016 which specifies input format and output format respectively - where
1017 format is one of "marc", "marcxml", "line", "marcxchange".
1019 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1020 does not print anything except warnings for records.
1022 For yaz-marcdump, added support for MARC split into files (-s) with a given
1025 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1026 spec, at http://www.loc.gov/standards/sru/record-update/
1027 This has changed the binary layout of the following structs:
1028 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1029 bend_update_rr . Patch by Ko van der Sloot.
1031 Added GFS utility function bend_assoc_is_alive which returns 1 if
1032 association is still alive (client is connected); 0 otherwise (client
1033 closed connection). This allows busy servers to stop working for
1036 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1037 been a separate piece of software. This version of ziffy has been modified
1038 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1040 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1042 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1043 Client code may now interrogate options such as "init_opt_sort" to
1044 find out whether the server claims to support various options.
1046 --- 2.1.40 2006/11/27
1048 Added utilities yaz_{set,get}_esn to set/get element set name from
1051 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1052 of YAZ and has been so since YAZ 2.1.10.
1054 Implemented ZOOM_record_error which returns error information for
1055 record (surrogate diagnostic).
1057 --- 2.1.38 2006/10/31
1059 Updates for SRU Update by Ko van der Sloot:
1060 1. Changed name from "operation" to "action"
1061 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1062 versions in the code, marked as 'backward compatible'.
1063 3. Added diagnostics for SRU Update.
1065 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1067 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1069 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1071 For GFS, fixed problem with SRU diagnostic 'First record position out of
1072 range' being issued for 0 hits.
1074 zoomtst10 part of Windows Build.
1076 --- 2.1.36 2006/10/13
1078 Implemented yaz_filepath_comp which splits a path into file path
1079 components (required by Zebra 2.0.3+).
1081 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1082 BSD inspired license until now so this should not have any real impact on
1083 anybody. See http://www.opensource.org/licenses/bsd-license.php
1085 Fixed bug #687: Missing log lines.
1087 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1090 Fixed bug #689: SRU diagnostics to be added.
1092 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1093 whether a connection is idle (no more work do do).
1095 --- 2.1.34 2006/10/04
1097 Change type of optval from long to int for invocation of setsockopt with
1098 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1100 Added support for specifying the max log file size for the Generic
1101 Frontend Server. The size is given with option -r.
1103 --- 2.1.32 2006/09/21
1105 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1107 --- 2.1.30 2006/09/17
1109 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1112 Fixed bug in Generic Frontend Server that could cause a server to stop
1113 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1115 For the generic frontend server, the maximum record size is used as maximum
1116 size of incoming packages (SRU + Z39.50). The value until was previously
1117 only used in Z39.50 Init negotiation and, later, in a session controlled
1118 sizes of records returned. This is controlled using -k option. It can be
1119 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1121 --- 2.1.28 2006/09/04
1123 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1126 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1128 New option for yaz-marcdump -lpos=value which allows setting a portion
1129 of MARC header to a certain value.
1131 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1133 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1134 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1136 --- 2.1.26 2006/08/15
1138 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1141 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1143 --- 2.1.24 2006/08/08
1145 Fixed MARC ISO2709 encoding routines to deal with character set
1148 Minor changes to GFS logging. Database included in search request log
1151 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1152 cached/multiple records.
1154 Shared libraries are built by default on Unix+configure.
1156 Changed cql2pqf transformation to use a different evaluation order. The
1157 new order is: always, relation, structure, position, truncation, index
1158 and relationModifier. Old order was: always, relation, relationModifier,
1159 structure, index, position, truncation. Note that the the latter ones
1160 override former ones for identical attributes.. The new scheme means that
1161 it is possible to override any existing attribute with a relationModifier.
1162 And also that it is possible to override everything for the index rule
1163 (except the ones listed in relationModifier). No order is perfect but this
1164 one, we believe, covers more real cases.. The "always" should have been
1165 called "default", since the attributes there can be overridden with all
1168 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1169 compilation phase, but also for yaz-config --cflags output. This allows
1170 us to have public headers with Libxml2 stuff in them . It should also,
1171 eventually, make Libxml2 checks redundant in packages using YAZ, such
1174 --- 2.1.22 2006/06/15
1176 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1177 stored in uri, message and details.. Previously diagnostics were stored
1178 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1179 compatibility.. but he's probably the only one affected, so.
1181 Added support for CCL, compiled on the client side, in ZOOM-C. This
1182 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1183 input; the resulting query objects can be used for for searching with
1184 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1186 YAZ' configure searches for OpenSSL by default.
1188 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1189 SL_CTX_use_certificate_file. See
1190 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1191 for more info. Thanks to Ko van der Sloot.
1193 --- 2.1.20 2006/06/02
1195 Bug #600: SRU GET, POST support for yaz-client. Introduced
1196 command 'sru' which selects method SOAP/GET/POST.
1198 Allow missingValueAction to be specified for the sortspec string -
1199 function yaz_sort_spec. By default, the missing value action is null.
1200 Use ! to specify "abort". Use = followed by stringvalue to specify default
1203 Ensured that Present-handler (if defined) is called in GFS before any call to
1204 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1205 searchRetrieve requests.
1207 Documentation for YAZ is now based on the Docbook XML/XSLT using
1208 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1209 is no longer depending on jade/openjade or docbook-to-man scripts.
1210 PDF is no longer part of the distribution - but can optionally be
1211 made using DSSSL/jadetex or FOP.
1213 Added retrieval handling support in Generic Frontend Server to support
1214 conversion between MARC/XML as well as XSLTtransforms. See
1215 etc/yazgfs.xml for an example.
1217 Added Authentication support to Generic Frontend Server in SRU
1218 mode. Authentication using HTTP Basic is supported, as is the use
1219 of 'x-username' and 'x-password' parameters in the request itself.
1221 Added support for a new character set MARC8s identical to MARC8 except
1222 that it converts combined characters to single Unicode characters in the
1223 Latin-1 range (when possible).
1225 --- 2.1.18 2006/04/24
1227 ASN.1 compiler 0.4: generates brief Doxygen file header for
1228 generated .h/.c files.
1230 Utility yaz_iconv now supports conversion to MARC-8.
1232 New facilities for the MARC module. The reading - and writing of
1233 content are separate methods for the yaz_marc_t handle. The following
1234 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1235 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1236 format). Write functions have prefix yaz_marc_write_.. The existing
1237 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1238 available. Removed support for OAI-MARC and simplexml (not the
1239 simplexml from PHP5).
1241 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1242 to be returned for this connection.
1244 --- 2.1.16 2006/03/31
1246 Allow multiple languages and charsets to be specified with
1247 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1248 negcharset iso-8859-1,utf-8
1250 Translation of proximity nodes from CQL into PQF now works.
1252 Moved to automake 1.8, 1.9.
1254 Added function yaz_log_set_handler which allows a log handler to be
1255 installed. This handler will be called for all log messages. Output
1256 to file is also produced; but that can be disabled by passing NULL
1257 fname to yaz_log_init_file.
1259 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1261 For SRW (including GFS), accept application/soap+xml as content-type
1264 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1265 produces NO stylesheet reference even if a default stylesheet is specified
1268 --- 2.1.14 2006/03/14
1270 Updated Windows package to include yazd.dll + yazd.lib for the
1271 Development component.
1273 If the environment variable YAZ_LOG is set, then it is used as a
1274 string indicating the default level of logging to use if not
1275 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1276 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1277 used as before. So, for example, to omit warnings from YAZ logging,
1278 export YAZ_LOG=-warn
1280 cql_transform() now map structure and other attributes before indexes,
1281 so that index-specific structures and other attributes can override
1282 defaults. So now a combination of mapping specifications such as:
1284 index.dc.date = 1=date-modified 4=5
1285 does the right thing.
1287 cql_transform() now also respects the "always" mapping specification,
1288 which establishes an initial set of attributes to be used for all
1289 terms except where overridden by more specific attributes associated
1290 with the index, relation or modifier.
1292 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1293 which mode to use; one of "post", "get" or "soap" (SRW, default).
1295 Fixes for yaz_iconv routines: changed trie-based character set conversions
1296 to use only non-negative values for bit fields due to Sun's C compiler not
1297 supporting negative values.
1299 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1300 sequences where not read correctly. Fix by Rustam Usmanov.
1302 Updated win/makefile to use options, settings which makes things
1303 compile with VS C 2005.
1305 --- 2.1.12 2006/02/01
1307 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1309 In ZOOM socket code, use select instead of poll on MacOSX.
1311 ZOOM-C now support client-side compilation of CQL into RPN that is
1312 sent to the server, enabling CQL to be used against all Z39.50
1313 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1314 ZOOM_query object, and submit it using ZOOM_connection_search().
1315 The CQL-to-RPN translation uses a configuration file, the name of
1316 which must be specified in the Connection's "cqlfile" option.
1318 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1319 function, which takes as its start-term parameter a ZOOM_query object
1320 (which may have had either CQL or RPN set into it).
1323 --- 2.1.10 2005/11/29
1325 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1326 GFS to support this as well. Backend handler, bend_srw_update, does the
1327 update work. Code contributed by Ko van der Sloot.
1329 Allow retrieval of Search Result-1 information in ZOOM by the use of
1330 options that are attached to a result set. ZOOM documentation updated
1333 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1334 UTF-8 conversion. Patch by Raj Patel.
1336 Added option -m to GFS to control formatting of timestamps in log file.
1338 Added 'exit' as synonym for 'quit' in yaz-client
1340 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1341 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1342 for the new members. Patch by Ko van der Sloot.
1344 Added support for SRU POST. It is supported for content-type
1345 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1347 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1348 Instead make the library libyaz.la multi-threaded. Threading as a whole
1349 can still be disabled by configure option --disable-threads. Previosly,
1350 with older GLIBCs there were problems with MT libs under Apache. This
1351 has now been fixed a long time ago.
1353 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1356 CQL module modified to be case insensitive for relations/indexes/operations.
1358 Fixed bug in CQL transform code: incorrect value relationModifieder
1361 Added 'show all' command for yaz-client which retrieves all results
1364 Added new yaz-client, xmles, which takes a (private) OID and
1365 a document to be sent as an extended service request.
1367 Describe new yaz-client commands wait_response and set_auto_wait.
1369 Increase TCP/IP listener backlog from 3 (which I am guessing was
1370 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1371 that the socket will queue as many incoming connections as it's able
1372 to handle ongoing connections. In other words, it will never now
1373 refuse a connection that it would be able to handle merely because
1374 it's not got around to accepting() enough of the pending connections
1375 yet. This is the behaviour anyway under Linux, where the listen()
1376 argument is ignored; but not under BSD and on systems such as
1377 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1378 YAZ-based servers should now be uniform across operating systems in
1381 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1382 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1383 This allows yaz-marcdump to read large MARC batches (>2 GB).
1385 Modified all YAZ source files - except the source which is auto-generated
1386 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1389 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1390 corresponding to the existing *_setl() function. These allow option
1391 values containing arbitrary valuues.
1393 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1394 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1395 except that it returns an indicator of whether or not the sort
1396 criterion was accepted (0 for OK, -1 for invalid).
1398 --- 2.1.8 2005/06/07
1400 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1401 MARC output rather than returning "new" buffer.
1403 yaz-client warns about unknown init options.
1405 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1407 --- 2.1.6 2005/05/24
1409 Added support for SRW sort in Generic Frontend Server. Patch
1410 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1411 sortKeys - or NULL if none is provided.
1413 Fixed bug #307: It was impossible to specify indefinite/no timeout
1414 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1417 Added support for multiple languages and charsets to be specified in
1418 ZOOM. Each charset/language is separated by a blank. If negotiation is
1419 in effect in init-response, Option
1420 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1421 Code based on patch by Vasiliy Osadchuk.
1423 Fixed bug #306: infinite recursion that occurred when calling
1424 yaz_log_level_init as the first call (before other log level or
1427 Fixed bug in scan handling in front end server: if preferred-Position-In-
1428 Response was non-present, a NULL pointer referece was performed.
1430 --- 2.1.4 2005/04/26
1432 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1433 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1434 now defined for all those error codes. So instead of putting 109 in
1435 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1436 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1438 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1441 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1443 Program yaz-client now exits and produces an error message if multiple
1444 Z39.50 servers are specified on the command line (none or one allowed
1447 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1450 --- 2.1.2 2005/03/16
1452 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1454 Fixed bug #272: Preserve spacing for CCL terms.
1456 --- 2.1.0 2005/03/14
1458 Added support for virtual hosts and multiple backend servers for
1459 the YAZ frontend server. The configution is XML based and
1460 support specificition of CQL to RPN mappings and explain information.
1461 See section "Virtual Hosts" in the YAZ manual.
1463 Extended OPAC display utility. OPAC display utility renders
1464 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1465 to supplement yaz_marc_decode_wrbuf.
1467 Fixed a bug in MARC decoder that could caused it to crash for some
1468 invalid MARC records. More diagnostics and warnings where added in
1469 XML output (warnings, etc are stored in comments).
1471 --- 2.0.34 2005/02/08
1473 Fixes for UNIX domain sockets. Bug #261.
1475 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1477 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1478 Added yaz_marc_subfield_str which defines subfield lead string which is
1479 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1480 yaz_marc_endline_str which defines end of fields string used in
1481 YAZ_MARC_LINE format. Default string is newline.
1483 Experimental support for MarcXChange. This format can be produced
1484 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1485 http://www.bs.dk/standards/MarcXchange.xsd
1487 Added yaz-client commands scansize that sets maximum number of
1488 entries to be returned by scan.
1490 --- 2.0.32 2005/01/11
1492 Added support for SRW scan in yaz-client and Generic Frontend Server.
1494 * Added whereInList member to SRW Scan Term.
1496 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1498 Fixed NMEM system to return aligned blocks on the smallest boundaries
1499 that are suitably aligned for all possible types on the particular
1500 architecture YAZ is being built for.
1502 --- 2.0.30 2005/01/04
1504 Fixed numerious warnings that was issued with newer versions of GCC.
1506 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1507 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1510 Make YAZ Generic Frontend Server slightly faster.
1512 Enhance (and reduce) logging for Generic Frontend Server.
1514 Revert YAZ log system so that it flushes every write operation
1515 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1517 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1518 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1519 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1520 will effectively disable old definitions.
1522 --- 2.0.28 2004/11/09
1524 Added yaz_log_time_format which specifies log format using
1527 Added yaz_log_module_level which returns mask for a module. Value
1528 is non-zero mask a if module is enabled; zero if disabled.
1530 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1531 in include/yaz/cql.h.
1533 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1535 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1537 Fixed bug #172: RPM builds does not enable SSL.
1539 Doxyfile.in part of dist. Doxyfile generated by configure.
1541 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1542 are given and the corresponding component does not exist.
1544 Extend CCL documentation in YAZ reference. Describe r=r.
1546 --- 2.0.26 2004/10/01
1548 Fixed MARC->MARCXML conversion to properly deal with
1549 fields, subfields, indicators having non-ASCII characters.
1551 Fixed MARC->MARCXML conversion so that ASCII control characters
1552 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1555 Added YAZ GFS support for conversion from Z39.50 surrogate
1556 diagnostics to SRW surrogate diagnostics.
1558 Bug fix: YAZ GFS did not return schema in explainResponse.
1560 --- 2.0.25 2004/09/30
1562 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1563 now converts recordSchema to elementSetName as well as schema URI.
1565 Fixed bug in COMSTACK that prevented HTTP request packages from being
1568 --- 2.0.24 2004/09/29
1570 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1571 does not require white-space before and after the dash in a range, e.g.
1572 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1575 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1576 due to new GCC removing "redundant" code.
1578 Added yaz-client commands scanpos and scanstep that sets preferred
1579 position and step-size for scan.
1581 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1583 Added CCL utility ccl_qual_buf which parses one or more CCL
1584 spec lines in a buffer.
1586 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1587 of name and value - ignoring empty lines and comments.
1589 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1591 Added odr_get_element_path which returns current element path for an
1592 ODR handle. This utility is useful in error handling or user-defined
1595 Added ODR_PRINT utility odr_set_stream which is is a more generic
1596 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1597 to a write function and pointer to close function. The close function - if
1598 non-NULL - will be called during odr_destroy.
1600 Fixed bug in CCL parser where truncation char was not removed from
1601 right side when truncation=both was in effect.
1603 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1606 --- 2.0.23 2004/08/11
1608 Fix buffer overrun in CQL parser when dealing with proximity (%).
1610 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1611 to UTF-8/UCS conversion is now only based on codetables.xml.
1613 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1615 --- 2.0.22 2004/08/06
1617 Add support for more "commit changes" in ZOOM (uses Extended Services).
1619 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1622 Yet another small fix for configure of SSL.
1624 --- 2.0.21 2004/05/14
1626 Fix SSL libs for configure when --with-openssl=DIR is given.
1628 --- 2.0.20 2004/05/10
1630 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1632 SSL comstack now uses yaz.pem certificate file on server side
1633 by default. Certificate filename can be configured by calling
1634 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1636 Fix bug regarding multiple calls to ZOOM_connection_connect.
1638 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1640 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1641 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1643 ZOOM now allows inspection of X509 peer certificate for verification.
1644 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1646 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1647 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1648 as "modular" but it simplifies things.
1650 Added cs_get_peer_certificate to that returns peer X509 PEM.
1652 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1653 NULL if SSL is unavailable.
1655 Documentation about MARC decoding tools.
1657 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1659 --- 2.0.19 2004/03/30
1661 Rename CHANGELOG to NEWS to follow GNU style packing.
1663 Fix bug with missing initialization of member in init_diagnostics.
1664 This bug affects threaded version of GFS server.
1666 --- 2.0.18 2004/03/20
1668 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1671 Ensure zlib.dll is packed with Windows install.
1673 --- 2.0.17 2004/03/17
1675 Fix encoding of xsd:string to use text instead of CDATA.
1677 Fix endless loop in CQL parser with unbalanced ".
1679 Use a more compact way to store MARC-8 conversion tables.
1681 --- 2.0.16 2004/03/16 Debian only
1683 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1686 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1691 --- 2.0.15 2004/03/01
1693 Another fix for decoding of XML packed records.
1695 --- 2.0.14 2004/02/25
1697 Fixes for Chunked encoding. White space not ignored after length spec.
1699 Update NS and use default NS for SRW diagnostic elements.
1701 --- 2.0.13 2004/02/23
1703 Implement ZOOM_resultset_cache_reset which resets record cache.
1705 Implement ZOOM_resultset_sort which sorts a result set.
1707 Implement chunked HTTP transfer.
1709 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1711 --- 2.0.12 2004/02/16
1713 Added member 'schema' to bend_explain_rr structure so that backend
1714 can specify explain record identifier. Defaults to Zeerex 2.0.
1716 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1718 --- 2.0.11 2004/02/16
1720 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1723 Added init command for yaz-client which sends "extra" init request.
1725 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1726 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1728 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1730 Make ZOOM error code for "invalid query".
1732 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1734 --- 2.0.10 2004/02/05
1736 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1739 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1741 Added option -p <file> to make Generic Frontend Server to write PID file.
1743 Added option -D to put Generic Frontend Server in background on its own.
1745 Make ZOOM C recognize option "password". If unset, "pass" is used
1746 (for backwards compatibility).
1748 Fixed a bug in Generic Frontend Server that could make it crash if a
1749 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1752 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1753 Must be issued before open, in order to be in effect.
1755 --- 2.0.9-6 2004/01/12 Debian/Windows
1757 Make the SRU server more picky WRT unknown params, etc.
1759 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1761 New YAZ client command, options, that sets Z39.50 options.
1763 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1764 options from a string of tokens (one token for each option bit).
1766 Update SRW diagnostic code messages.
1768 --- 2.0.9-5 2004/01/07 Debian/Windows
1770 Handle user defined stylesheet for SRW/SRU.
1772 --- 2.0.9-4 2004/01/06 Debian/Windows
1774 Fix bug in decoding of Content-Length.
1776 --- 2.0.9-3 2004/01/06 Debian/Windows
1778 Fix a bug with decoding of XML packed records.
1780 --- 2.0.9-2 2004/01/05 Debian only
1782 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1784 Fix bug in SRW/SRU diagnostics decoding.
1786 --- 2.0.9 2004/01/05
1788 Fixed bug in Generic Frontend Server which could drop records exceeding
1789 preferred message size. Reported and fixed by Irina Dijour.
1791 Fixed calculation of package size for structured records in Generic
1792 Frontend Server. Reported and fixed by Irina Dijour.
1794 Fixed namespace for SRW/SRU diagnostics.
1796 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1798 --- 2.0.8 2003/12/22
1800 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1801 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1804 CQL changes to reflect recent changes to the specification:
1805 * Documentation talks about context sets instead of index sets.
1806 * Documentation talks about indexes instead of qualifiers.
1807 * The CQL-to-PQF transformer's configuration file now uses
1808 "index.set.name = <attributes>" instead of the old form
1809 "qualifier.set.name = <attributes>". (Both forms are still
1810 understood but the latter is deprecated.)
1811 * CQL terms with no explicit index specified are now interpreted as
1812 cql.serverChoice instead of srw.serverChoice (which of course
1813 behaves exactly the same.)
1815 --- 2.0.7 2003/12/16
1817 MARC conversion can now generate ISO2709 output in another
1818 character set. yaz-marcdump uses this facility if you invoke it
1821 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1822 functions from there can be used from C++.
1824 --- 2.0.6 2003/12/04
1826 Frontend server now transfers memory from decoded packages to stream
1829 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1830 references to show up.
1832 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1833 the ZOOM Abstract API. The older names for the same options are still
1834 also supported for the benefit of old applications.
1836 ZOOM-C supports "implementationId" and "implementationVersion" options
1837 to go along with "implementationName". These allow the user code to
1838 specify identification strings to be sent to servers.
1839 Add OID for the new ExtLite attribute set.
1841 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1842 as requested/supplid by Ere Maijala <ere@atp.fi>
1844 For generic frontend server, reverse the order of
1845 "toolkit-supplied / application-supplied" strings sent as implementationId,
1846 Name and Version. Also, remove the spaces around the slash. This brings
1847 the GFS in line with the behaviour of ZOOM-C on the client side.
1849 Add function ZOOM_scanset_display_term.
1851 yaz-client shows scan displayTerm if present.
1853 Utility yaz-iconv is now installed by default along with the man page
1856 Extend configure check for OpenSSL to use pkg-config where available (such
1859 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1860 server to specify uid/gid/mask for socket using the format
1861 unix:[user=uid,][group=gid,][umask=mask,]file=path
1862 If file= is omitted the existing format is assumed, e.g.
1864 in which case the mask is 0666 (rw for everybody).
1866 Major restructure of YAZ source. All source in libyaz is in src directory.
1867 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1868 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1870 Added man page for utility yaz-marcdump (used to be called marcdump).
1871 yaz-marcdump is installed by 'make install'.
1873 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1874 of incoming package failed.
1876 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1878 Change prototype of odr_perror: add const to message string.
1880 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1882 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1883 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1884 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1885 DNS lookup. There should not be any compatibility problems with this
1886 assuming that blocking=1 or 0 is used.
1888 Fix bad reference in UNIX comstack in function cs_addrstr.
1890 Fix for compilation on AIX.
1892 The generic front-end server (server/seshigh.c) now supports returning
1893 Init diagnostics to the client in User-information-field, in
1894 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1897 --- 2.0.4 2003/09/04
1899 Allow any CQL relation (not just all,any,exact,scr).
1901 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1902 that features the same UI.
1904 Implemented command update0 in YAZ client which is equivalent to
1905 update but uses old of Ext Update ASN.1.
1907 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1908 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1909 Previously no OID was used for this info.
1911 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1912 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1913 returns 'malformed search term' otherwise.
1915 SortResponse member resultCount now set to NULL in sort handler of
1918 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1921 Add three new utility functions for translating OIDs between various
1922 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1923 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1924 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1925 char *oid_to_dotstring(const int *oid, char *oidbuf);
1926 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1928 Reverted modifications for ES Update definition for z_IU0Update
1929 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1930 is back to YAZ 2.0.2.
1932 String value attributes for CCL parser.
1934 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1935 which their FirstSearch server returns in Init responses, sometimes
1936 carrying useful diagnostic information when Init fails. This has the
1937 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1938 "z39.50/oclcui.asn", where its definition is somewhat different from
1939 what OCLC document on their web-site, as required to interoperate with
1942 Support for anonymous authentication in yaz-client. Use the command
1945 * Fix the OID of the Index Data-local "admin" Extended Service from
1946 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1947 the 1000, which indicates a locally-defined OID, was a mistake.
1949 --- 2.0.3 2003/06/20
1951 Fix CCL directive @case handling so that it affects string match for
1952 both CCL keywords and qualifiers.
1954 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1955 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1956 Decoder has been updated with ASN.1 changes as listed in
1957 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1958 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1959 z_IUUpdate, remains unchanged.
1961 ZOOM_record_get may now return a record in a specific character set.
1962 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1963 "from" is the character set of record as returned by target. "to" is
1964 the character set to be returned. If omitted, "to" is UTF-8.
1966 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1968 New ODR utility, odr_getelement, which returns name of element for
1969 which encoding/decoding failed.
1971 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1972 in cases where a required element was omitted.
1974 Bug fix: some MARC8 sequences were not converted.
1976 New ZOOM option "step" which specifies number of records to be
1977 retrieved in one chunk. Used in conjunction with "start" and "count".
1979 SRW support for yaz-client. Use scheme http: to use it, e.g.
1982 yaz-client no longer does (un)intelligent character set conversions
1983 by default. Can be enabled with charset and marc_charset commands.
1985 xmalloc trace fix for 64-bit systems such as DEC alpha.
1987 Solaris 2.6 compile fix.
1989 New function, cql_strerror() translates SRW error codes, as returned
1990 by cql_transform_error(), into human-readable English strings. Used
1991 in yaz-client diagnostics when appropriate.
1993 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1994 converts it into a type-1 query which is sent to the server. This
1995 makes CQL available for use with all Z-servers, as opposed to the tiny
1996 minority that can handle CQL queries themselves.
1998 --- 2.0.2 2003/04/28
2000 New Debian package layout similar to the Redhat Package layout.
2002 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2003 and search result respectively.
2005 --- 2.0.1 2003/04/25
2007 Redhat package is now several packages: libyaz (runtime libraries),
2008 libyaz-devel (development and documentation, and yaz (utility programs).
2009 Package spec file by Morten Bogeskov.
2011 New member 'schema' in struct bend_fetch_rr which the name of requested
2012 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2013 handler MAY set this to reflect the schema of the returned record.
2015 New member 'display_term' in struct scan_entry. GFS now sets member entries
2016 and allocates scan entries to be filled by user scan handler. In previous
2017 version, entries member was allocated by the scan handler. That still works,
2018 but the GFS will ignore member display_term - assuming it was NOT set by
2019 the handler. The fact that the GFS now allocates the entries both allows
2020 for new members and makes a scan handler easier to write.
2022 Fix CQL lex buffer overflow.
2024 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2025 SRU default recordPacking is string.
2027 SRU protocol support for frontend server.
2029 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2031 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2033 Added scan for the ZOOM shell (zoomsh).
2037 * String Identifers for Schemas (Amendment 5).
2038 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2039 Old definition for schema
2040 Odr_oid *schema; /* OPT */
2045 Z_InternationalString *uri;
2046 #define Z_Schema_oid 1
2047 #define Z_Schema_uri 2
2050 * resultCount parameter to Sort Response (Amendment 1).
2051 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2053 Support for SRW 1.0 over HTTP. This is an optional feature and
2054 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2057 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2058 on the same port. SRW SearchRetrieveRequests are mapped
2059 to bend_init,bend_search,bend_fetch,bend_close.
2061 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2063 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2064 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2066 ZOOM connections are SRW based if schem http is used for hostname
2067 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2068 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2070 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2071 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2072 distance=n, order=true/false, relation=le, prox unit=word. If
2073 n is omitted, distance 1 is used.
2075 Fixed problem with C compiler include path in wrong order.
2077 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2078 on Solaris. Patch from Ko van der Sloot.
2080 New MARC decode API. All new functions operate on a yaz_marc_t
2081 handle. The most important new functions are: yaz_marc_create,
2082 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2083 decode and destroy respectively. Decoder can produce formats
2084 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2085 include/yaz/marcdisp.h.
2087 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2088 to UTF-8, UCS-32, wchar_t or Latin-1.
2090 * Prototypes for yaz_iconv_-functions moved to separate header
2091 include/yaz/yaz-iconv.h.
2093 Make a few private functions 'static' in unix.c. This prevents
2094 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2096 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2097 are set when Init Response is received.
2099 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2100 but returns diagnostic set as well.
2102 New function yaz_strerror which is a portable wrapper for
2103 strerror/strerror_r/GetLastMessage.
2105 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2106 is returned for MARC. If type is "oai", then OAI MARC is returned.
2108 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2111 --- 1.9.2 2002/11/26
2113 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2115 Fix bad race conditions on SIGTERM and terminate gracefully in
2118 Move retrieval (data1) module to Zebra since nobody seems to be
2121 Add GRS-1 render for ZOOM using same format as yaz-client.
2123 --- 1.9.1 2002/10/05
2125 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2127 Fix broken ESpec handling in data1 module.
2129 SGML reader parses comments and makes them part of the data1 tree.
2131 Added several type casts so that YAZ compiles as C++ code.
2133 ZOOM didn't handle PDU encoding failures properly.
2135 Added more Bib-1 diagnostics (approved extensions).
2137 GNU configure: better check for iconv.
2139 More portable use of accept, getpeername. Check for socklen_t. Use
2140 int/size_t if socklen_t is not defined.
2144 PQF parser rejects bad queries - including those with extra
2145 characters in them. PQF parser used to silently ignore that.
2146 Cleaner API for PQF added, which allows you to get detailed
2147 error information for bad queries (see yaz/pquery.h).
2149 Fixed bug in ZOOM_record_get for type "database".
2151 Implemented mini iconv library supporting conversions between
2152 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2154 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2156 --- 1.8.9 2002/08/20
2158 Fixed ZOOM C record cache so that preferredRecordSyntax and
2159 elementSetName is used to check for already fetched records.
2161 --- 1.8.8 2002/08/02
2163 Added three members in bend_initrequest structure to facilitate
2164 character set negotiation.
2166 Fixed a bug in frontend server that could cause indefinite
2167 loops under rare conditions.
2169 Revised character set utilities (charneg.h) so that encoding
2170 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2172 For PQF, directive @term <type> sets term type for Scan/Search.
2173 Here <type> is general, string, numeric, null. The term type
2174 is inherited - just like @attr.
2176 New call odr_set_charset that sets character set conversion for
2177 international-strings on a ODR stream. Prototype is:
2178 int odr_set_charset(ODR o, const char *to, const char *from);
2179 The InternationalString is still represented as C string in YAZ
2180 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2181 won't). On the protocol level, you can use any encoding.
2183 Support for UNIX sockets in ZOOM.
2185 Solaris recv sometimes returns errno == ENOENT. It is treated as
2186 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2188 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2189 both client and server. Code by Morten Bogeskov.
2191 --- 1.8.7 2002/05/22
2193 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2194 that they can be used directly from Visual Basic. You must recompile
2195 your windows APP if you're using ZOOM.
2197 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2198 Commands "lang" and "charset" sets language and character set respectively.
2199 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2200 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2202 Attributes from multiple CCL fields may be OR'ed rather than merged
2203 using directive "@field or". Fields are still merged by default -
2204 equivalent to "@field merge".
2206 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2209 Fixed bug in zget for parameter ExtendedServicesResponse.
2213 --- 1.8.6 2002/03/25
2215 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2217 Client displays USR.1:SearchResult-1 (hits per term).
2219 Additional Search Info for search in Generic Frontend Server.
2221 Fixed CCL parsing of "field=s".
2223 WIN32 installer - using the excellent NSIS software from nullsoft.
2225 Fixed CCL parsing of "field = - <number>".
2227 Added function yaz_marc_decode that decodes MARC for line mode
2228 display or XML (similar to that used by JZKit).
2230 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2231 Z39.50. But ISO/ILL was, however.
2233 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2234 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2236 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2237 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2239 --- 1.8.5 2002/02/03
2241 New YAZ client features: Command completion and new commands:
2242 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2243 Code provided by Jacob Poulsen.
2245 New call oid_trav, that visits all registered OIDs via callback.
2247 Function ZOOM_record_get now returns const char pointer rather than
2248 void pointer. It saves a lot of type casts.
2250 For YAZ client, command "auth" now allows you to set authentication
2251 in IdPass style. It is enabled when three tokens are given - order
2252 is user, group and password.
2254 Fix memory leaks in MARC record handling for ZOOM.
2256 New option for YAZ client, -k <kilobytes> that sets
2257 maximum record size. Similar to -k option for generic frontend
2258 server and yaz-ztest.
2260 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2262 Prefix query parser reports "fail" when bad attribute set is given.
2264 Fix in MARC decoder. Proximity logging. Fix for attribute set
2265 in scan handler for server. Patches by Shigeru Ishida.
2267 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2270 Configure option --with-openssl=<dir> now works when a directory is
2271 specified. Patch provided by Morten Bogeskov.
2273 New option for YAZ client, -u <auth>, that sets authentication.
2275 ZOOM fix: error information was sometimes "missing", since error
2276 was cleared/reset too when it shouldn't.
2278 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2280 --- 1.8.4 2002/01/04
2282 Scan for ZOOM API. New object ZOOM_scanset. New functions
2283 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2284 ZOOM_scanset_destroy.
2286 New ZOOM function, ZOOM_connection_last_event, that returns type
2287 of last event (such as "receive data", "send data", "apdu received",
2290 New ZOOM option, schema, that specifies schema for retrieval.
2292 New CCL feature. Qualifiers can be aliases for one or more
2293 other qualifiers (if more than one is given, OR is used).
2295 ZOOM uses named result sets if target supports it.
2297 Two new YAZ client commands: . (dot, which sources a script of YAZ
2298 client commands), and ! (to execute shell command.). Implemented
2301 Working on Debian packages.
2303 --- 1.8.3 2001/11/19
2305 YAZ client enables named result sets only if target supports it.
2307 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2309 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2310 with key="host" to get same result.
2312 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2313 Function Z3950_resultset_record(s) returns references to records
2314 "owned" by resultset. To become owner use Z3950_record_clone.
2316 Function z_ext_record handles Extended Services. Thanks to
2319 --- 1.8.2 2001/11/12
2321 CCL Parser fix: ignore token comma when dealing with and-lists.
2323 Documentation updates for COMSTACK.
2325 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2326 Changed prototype Z3950_records. For some functions, int parameters
2327 were changed to size_t.
2329 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2332 New MARC decode/display function, marc_display_exl, which properly rejects
2333 non-ISO2709 records. YAZ client uses it.
2335 --- 1.8.1 2001/10/29
2337 Fix bug: local attribute set wasn't set correctly in PQF strings.
2341 * Old Z39.50 codecs no longer supported.
2343 Added ZOOM C binding. See http://zoom.z3950.org/
2345 Renamed states for COMSTACKs to avoid confusion with events.
2347 Implemented cs_look and proper cs_rcvconnect.
2349 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2351 Configure detects POSIX threads on OpenBSD.
2353 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2354 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2356 When error is returned from present handler, non-surrogate diagnostic
2357 is returned in present response (and fetch handler is no longer called).
2359 * Minor adjustments to pquery parser (PQF). Token characters may be
2360 escaped by using backslash (C-style).
2362 PQF parser allows string attribute values to be specified. For @attr,
2363 non-numeric characters after the equal-sign are treated as strings
2364 (e.g. @attr 9=title).
2366 CCL trunction character may be defined (@truncation in file)
2368 * function zget_ExtendedServicesRequest sets waitAction to
2369 waitIfPossible (was wait).
2371 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2374 CCL operator names may be set in field definition files (CCL_bibset).
2375 See ccl/bib1 for an example.
2377 Fixes in ASN.1 compiler for C++ compatibility.
2379 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2380 and "op_or" to avoid conflict with C++.
2382 Fixed problem with GNU readline detection on Redhat 7.0.
2384 Added step-size for Scan backend handler.
2386 Fixed bug that made the frontend server crash when no attribute
2387 set was specified for scan.
2389 Front-end server automatically switches to original working directory
2390 when installed as an NT service. Previously -w had to be specified to
2393 Added extended attributes for retrieval module (data1), so that data1
2394 records carry d1_readXML/SGML attributes. d1_read also supports
2395 null-data rules ( <tag/>)
2397 On UNIX when POSIX threads are available, a separate library libyazthread
2398 is created. Programmers should link with that library and the yaz library
2399 when using threads. The reason for the split was that some applications
2400 on Linux, such as Apache, doesn't work well when using shared objects that
2403 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2404 (or any frontend server) in SSL mode by specifying ssl: followed by
2405 address. Only tested on UNIX.
2407 Added feature for CCL module. Virtual structure s=al or s=ol generates
2408 and-list and or-list respectively instead of phrase search.
2412 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2413 log_mask_str. This was done to avoid name conflicts with other libraries
2414 (such as other PHP extensions).
2416 Added raw OID member for preferred record syntax (request_format_raw)
2417 and returned record syntax (output_format_raw) for backend fetch method.
2419 Config file yaz-config now accepts options so that it returns specific
2420 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2422 Shared library support for UNIX using GNU libtool.
2424 * Modified backend interface. Request/Response struct's replaced by
2425 one read/write C struct. For example bend_fetchrequest and
2426 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2427 Every handler - even search has to be registered in bend_init
2428 handler. This means that the YAZ library no longer refers to
2429 external functions and it makes it possible to make the whole
2430 thing a single DLL/SO.
2432 Added Segment handler for backend server.
2434 Added Zmbol/Zebra administrative functions to YAZ client.
2436 Threaded frontend server on UNIX (when POSIX Threads are available).
2437 Starting the server with option -T enables multi-threading.
2441 Added configure option --enable-comp/disable-comp to control use
2442 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2443 located in sub directory asn.
2445 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2446 in ${exec_prefix}/bin along with the other programs yaz-client and
2449 GNU automake used to maintain makefiles.
2451 Added several OID's.
2453 Changed retrieval module so that we can load records with no abstract
2454 syntax defined. Tagpaths in these records are fully composed of string
2457 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2461 On UNIX, the generated makefile now supports a proper 'make install'.
2462 The prefix can be set via GNU configure to set the install location
2463 (default is /usr/local).
2465 * YAZ programs client and ztest were renamed to yaz-client and
2466 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2467 locations, such as /usr/bin,/usr/local/bin,etc.
2469 * YAZ Header files were moved from include to include/yaz. YAZ Header
2470 files are referred to as include <yaz/log.h> rather than <log.h>.
2471 The YAZ include path (-I ..) is therefore the same as before. Programmers
2472 should update their #include statements or use -Ipath/include/yaz
2473 instead. The main motivation for doing this change is that YAZ header files
2474 can be installed in "standard" locations /usr/include,/usr/local/include
2475 without introducing conflicts, since ALL YAZ header files are stored
2476 in subdirectory yaz (under /usr/include for example).
2478 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2479 rather than project/workspace files. We switched because project files
2480 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2483 Changed name of logging function, logf, to yaz_log, to prevent name
2484 clash with some math-log functions. The YAZ header log.h defines logf
2485 to yaz_log (#define) so there should be no incompatibilities by this
2488 Added bend_start/bend_stop handlers for server. These handler are
2489 called on start/stop of server. For windows they are called whenever
2490 a service is started/stopped.
2492 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2493 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2494 in util/yc.tcl. The auto-generated C code structures are, in a few
2495 cases, incompatible with the old decoders. There are differences in the
2496 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2497 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2498 The preprocessor variable ASN_COMPILED is defined when the compiled
2499 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2500 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2501 wish to use the old encoders/decoders you can specify --disable-yc
2504 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2505 version so that it supports both new - and old version of DB Update
2507 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2508 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2509 change. The name parameter can be set to 0 in which no name is specified
2510 for the construction. The macros odr_implicit and odr_explicit sets name
2511 parameter to zero for the construction involved. New macros
2512 odr_implicit_tag and odr_explicit_tag are similar to the others,
2513 except that a name parameter is added. For programmers' that don't use
2514 ODR they probably only need to change the call to z_APDU and z_External.
2516 Added access control facility by interfacing the TCP wrapper library.
2517 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2518 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2519 name of the daemon and enables the access control as specified in
2520 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2522 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2523 den Dool <H.M.vdnDool@kub.nl>.
2525 Added reference ID parameter to most functions in server API - refer
2526 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2528 Changed name of ccl library to libccl.a (was ccl.a).
2530 Fixed bug in decoder for Explain (Category TargetInfo).
2532 Added support for GNU readline in client. Thanks to Jacob Poulsen
2533 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2535 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2536 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2537 IMPLEMENTATION! This change was made to the development version before
2538 the ZIG decided to retract the amendment. If any users MUST be
2539 compatible with the original Update definition, PLEASE CONTACT US, and
2540 we will include a separate definition corresponding to the old Update
2541 ES. Note that because of the change to the ASN.1 of the
2542 TaskPackageRecordStructure we cannot define a single structure that
2543 will support both versions.
2545 * Added const modifier to buffer parameter for some ODR/BER encoding
2546 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2547 completeWAIS, odr_dumpBER.
2549 Fixed bug in client.c which caused a crash when a scanResponse didn't
2550 contain positionOfTerm.
2552 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2553 * will cause an error in a client if a non-YAZ target sends both a
2554 * list of Scan entries and non-surrogate diagnostics.
2556 Retrieval module enhancements. Tag sets may be typed in the reference
2557 to it. From the .abs-file the "tagset" directive takes a third optional
2558 integer type for the tag set referenced. From a .tag-file the "include"
2559 directive takes a third optional type as well. The old "type" directive
2560 in the tag set itself is still recognized but acts as the default type
2563 Backend interface change. Individual Scan terms returned from bend_scan
2564 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2565 in include/backend.h.
2567 Retrieval module enhancements. Multiple tag sets and attribute sets may
2568 be specified in abstract syntax specs. Revised the error/warning for
2569 logging messages reported by the retrieval module when reading the
2572 Object Identifier system (oid_..) changed. The API is backwards
2573 compatible but the oid-routines now allocates new OID's when needed.
2574 Raw OID's may be specified in oid_getvalbyname.
2576 YAZ now uses GNU configure to generate Makefile(s).
2578 * Minor changes in some of the member names of DeleteResultSetRequest and
2579 DeleteResultSetResponse. See include/proto.h.
2581 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2582 and added member 'languages' in TargetInfo (which was missing).
2584 Changed the way attribute sets are handled in the retrieval
2585 module. These are now cached, just like the abstract syntaxes
2588 Changed YAZ so that it links with compiled ASN.1.
2590 Added Explain-schema definitions and mapping routines. The following
2591 Explain categories have been implemented: AttributeDetails,
2592 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2594 Fixed minor bug in Windows version of Server Library.
2596 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2598 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2600 Added EXTERNAL: UNIverse Resource Report (non-standard).
2602 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2603 ENUMERATED and SET OF.
2605 * Added 'const' to some of the char pointer arguments for the
2606 functions, data1_read_node, data1_getelementbytagname,
2607 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2610 Fixed bug in data1_insert_taggeddata - the last_child member of
2611 parent wasn't initialised.
2613 * Changed data1_read_record and data1_read_node so that the supplied
2614 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2615 doesn't refer to any parts of the "SGML"-buffer.
2617 Fixed bug in server library (Windows version of statserv_remove).
2619 * Changed code so that it compiles as C++. The type definition
2620 of Odr_fun which is a member of Odr_arm was changed. The result is,
2621 that an explicit typecast is needed for the fun pointer when
2622 using Odr_arm - as in:
2623 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2625 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2627 Implemented the new structured date and time definition as approved
2628 by the ZIG. Added schemaId element to the specificTag in Espec-1
2629 (also approved at the last ZIG). Thanks to RVDM.
2631 Added some Object identifiers (RVDM).
2633 Changed the Update Extended Service (RVDM).
2635 Added command "refid" to client which specifies referenceId for
2636 the following requests.
2638 Implemented extended service handling for server. See ztest.c
2639 for an example as well as backend.h. New handlers are registerd
2640 in the Init handler.
2642 * Changed interface for sort in server.
2644 Added new members to statserv_options_block. It allows a server
2645 to read options from another source than just the command line. Thanks
2646 to Charles Woodfield.
2648 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2649 renamed to zboolean. Some C++ compilers complained about the name.
2651 Minor changes to gils.abs. Added index 's' (sort) on title
2652 and date/time-last-modified.
2654 --- 1.4pl2 1998/1/30
2656 Fixed bug in server library regarding inetd mode (-i). This bug
2657 was introduced by release 1.4.
2659 --- 1.4pl1 1998/1/29
2661 Added sort facility in client and backend server interface.
2663 Fixed problem with dependencies in Makefile(s).
2665 Fixed bugs for encoders/decoders of extended services and
2668 Implemented sub-tree feature for schemas. Sub-trees are
2669 referenced in *.abs-files. See explain.abs for an example
2670 of the use of this feature.
2672 Modified bib1.att; local attributes for ANY didn't include
2673 ANY itself (only affects use of the retrieval module).
2675 Fixed bug in plain SGML reader in function data1_read_node:
2676 tags with prefix "var" was incorrectly interpreted as variants.
2678 Added feature "sub-schemas" to enable references to - and definitions
2679 of - group of elements.
2681 * Removed member parent from type data1_element (in data1.h).
2683 Implemented function odr_nullval() that returns the value of
2686 * Removed member num_children from data1_node (in data1.h).
2688 Made NT service interface part of the server library. The
2689 function statserv_main uses the NT service when required and
2690 calls the statserv_start / statserv_close routines.
2692 Routine zget_SearchRequest and zget_PresentRequest fills
2693 resultSetName/Id member with "default" instead of "Default".
2695 Fixed memory leak in server. Request queue member wasn't freed.
2697 Fixed nmem_exit so that memory is freed.
2701 Revised the CCL parser utility to be thread safe.
2703 Added function, oid_ent_to_oid, to replace the function
2704 oid_getoidbyent, which is not thread safe.
2706 * Added nmem_init and nmem_exit to initialize and release
2707 NMEM resources. Function nmem_init should be called once in the
2708 initial thread before NMEM/ODR is used. statserv.c and client.c
2709 have been changed accordingly. The change was necessary to make
2710 NMEM thread safe. The NMEM memory pool is shared amongst threads
2711 in a process. Unix-based applications will still work fine without
2714 Added NT Services interface for the the Z39.50 (statserv) Server.
2715 Refer to the ztest.c source on the usage.
2717 Windows 95/NT port using MSVC5.0. Project files are included in the
2720 * Defined new 'global' handle for the retrieval (data1) system. The
2721 new handled, data1_handle, describes the state of the data1 system.
2722 This handle is passed as first argument to virtually all
2723 data1 related routines. The functions data1_create and data1_destroy
2724 creates and destroys a data1 handle respectively.
2726 Added ODR encode stream member to all backend request structures
2727 init, search, scan etc. This stream should be used to allocate all
2728 memory used for the response when thread safe operation is needed.
2730 Changed the comstack utility, cs_addstr, to be thread safe. The
2731 returned hostname string returned by the function is now part the
2734 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2735 function. The cs_straddr takes a COMSTACK handle as argument, so this
2736 function must be used after cs_create and before bind/connect.
2737 This function is thread safe.
2739 Moved test server to 'ztest' directory - generic server code still
2740 in 'server' directory.
2742 Made prefix query (pquery.c) utility thread safe.
2744 Added new function modifier YAZ_EXPORT to 'export' public DLL
2745 functions when using windows (see include/yconfig.h).
2747 Added definitions to the OID database (util/oid.c) (RVDM).
2749 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2751 Added call to ccl_rpn_delete in client program.
2753 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2754 release of RPN structure.
2756 Added support for C++, headers uses extern "C" for public definitions.
2757 With input from RVDM.
2759 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2760 Thanks to Ronald van der Meer (RVDM).
2762 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2764 Added support for private extensions to the OID database
2765 (oid_setprivateoids()). Thanks to RVDM.
2767 Added optional, physical ANY (key replication)
2769 Fixed null-reference problem in GRS-1 output filter.
2771 Proximity operator added to Prefix Query Format (PQF).
2773 In test client command "base" accepts multiple databases.
2775 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2779 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2781 Smallish bug-fixes in the new encoders/decoders (explain).
2783 Bug fixed in DeleteRequest.
2785 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2787 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2789 Added SOIF syntax (using private OID for now) to retrieval module and client.
2791 Added Update extended service.
2793 Added SearchResult-1 additional info structure.
2795 Added optional CCL (ISO8777) interpreter as separate module. Available
2798 --- 1.2 1996/6/10 (1st anniversary release)
2800 Added Summary record syntax. Lightly tested.
2802 Added OPAC record syntax. Untested.
2804 Added ResourceReport service encoders/decoders. Untested.
2806 Fixed bug in z_Unit - wrong tagging on unitSystem.
2808 Fixed bug in the DiagRecs decoder.
2810 Added options for max PDU size and session timeout to frontend-server.
2812 Added documentation of query-language parsers and other supporting utilities.
2814 [frontend-server] Added Attribute set to the bend_scanrequest API.
2816 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2817 surrogate diagnostics were generated.
2819 [retrieval] Allow multiple local values for attribute.
2821 [retrieval] Allow multiple attributes per element in .abs files. index type.
2823 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2825 --- 1.1pl2 1996/4/10
2827 Minor changes, mostly specific to Zebra's requirements (retrieval)
2831 Repaired bug in frontend server when running multiple listening
2832 endpoints in dynamic mode.
2834 z_External() now won't break if a known, ASN.1 value comes encapsulated
2835 in an octet-string. The value will pass through unmodified in an Odr_oct.
2837 Added a bit of code to the demo client to decode & display
2838 ASN.1-structured records represented in the octet-aligned branch of
2839 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2841 Added z_ext_getentbyref() to the ASN module. Doc updated.
2843 * Completed the SCAN definition in the ASN module. This may break SCAN
2844 code based on older YAZ-versions at compile-time. The fix is easy -
2847 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2848 under the SCAN definition. Remember to initialize this, server-people.
2850 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2851 that this does not extend to ODR and ASN.
2853 Comstack allows insertion of established socket (primarily for
2854 inetd-operation of servers). Doc updated.
2856 Front-end server can now start from the inetd in TCP mode. Doc
2859 --- 1.0pl4 1996/1/24
2863 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2864 the rank and record number.
2866 Adjustments to the frontend server.
2868 Fixed diagnostic BER dumper. It ignored the file argument.
2872 Various changes to retrieval module.
2874 Changed the union discriminators of the protocol files from enums to
2875 ints paired with #defines.
2877 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2880 *Changed operator in the RPN structure to 'roperator', again to avoid a
2883 Fixed problems in Explain decoders/encoders.
2885 --- 1.0pl2 1995/12/6
2887 Memory bug in log module fixed.
2889 --- 1.0pl1 1995/12/5
2891 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2893 Bug in Explain DatabaseInfo module fixed.
2895 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2899 The shift to v1.0 signals that we now consider the *core* functionality
2900 of YAZ reasonably stable (the core being more or less equivalent to
2901 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2902 tested (Explain not at all - though that will happen soonish).
2904 Minor changes to code to support Windows port.
2906 Various minor changes after we're getting to use GRS-1 & co. more.
2908 Added Espec-1 format.
2910 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2911 of the protocol and it cannot be selected when encoding (maps into 'string'
2912 when decoding). Needed to talk to some servers.
2914 Demo client can request simple element set names.
2916 Added Diagnostic Format encoders/decoders.
2918 Added simple Close handling to frontend server (no hooks for resource
2919 reporting yet), and demonstration client.
2921 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2923 --- 1.0b3 1995/08/24
2925 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2926 handled incorrectly when records were requested in the searchResponse. This
2927 will only affect you if you use the frontend-server.
2929 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2930 Test-client will ask for and print GRS1. Ztest will return dummy records
2933 Added Explain encoders/decoders to the service-level API. Untested.
2935 Added Extended Services: Item Order encoders and decoders to the Service-
2936 level API. Untested. We could use a recent copy of the pertinent bits
2937 of the ILL protocol to add those bits.
2939 Added diagnostic format 1 encoders/decoders to the service-level API.
2942 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2943 odr_cons.c, which causes a more correct output.
2945 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2946 was always set to 0 when no records were requested in the searchRequest.
2948 * Added better external-handling. This shouldn't harm old code that
2949 *encodes* externals. It can break code that looks for a
2950 'single-ASN1-type' representation, since those types that are known
2951 are now decoded immediately. Look at the SUTRS sample code in
2952 seshigh.c and client.c. Documentation updated.
2954 Handling of structured records in bend_fetchresponse. Length -1 marks
2955 structured record, type is deduced from format field.
2957 --- 1.0b2 1995/06/27
2958 Fairly quick maintenance release to add SUTRS support.
2960 Fixed handling of SUTRS records in the demonstration client.
2962 * Added format field to the bend_fetchrequest and bend_fetchresponce
2963 structures of the backend API (frontend server). When the record is
2964 returned, the value of the format field is mapped to an OID. The
2965 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2966 of the record. The special value VAL_NONE in the bend_request means
2967 that no specific format was requested by the client. Documentation
2968 updated accordingly. Test server (ztest) will return a fixed dummy
2969 SUTRS record if your client requests SUTRS.
2971 Documentation updated accordingly.
2973 You can now set external libraries and RANLIB support in the top-level
2977 First public release.
