3 Make compilation work without Libxml2.
5 yaz-client: remove redundant blanks in display of searchResult-1 term
10 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
11 resulting CQL node (tree) in a new node CQL_NODE_SORT.
13 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
14 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
15 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
16 Note that the CQL sortby spec is only converted when the GFS is already
17 converting from CQL to RPN (cql2rpn element).
19 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
20 specify whether to collapse delimitors or not. The existing nmem_strsplit
21 do collapse (collapse parameter = 1).
23 Windows installer: For NSIS, set InstallDir depending on x86/x64.
25 Rename internal func yaz_use_attribute_create. While non-static, this
26 function is not declared in a public header.
30 Add -lCrun when linking with ICU on Solaris.
32 More quicks character set conversions for OPAC records.
36 fix problem with record_render: records were converted (character set
37 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
41 SRU: add methods for handling DADS SRU-proxy facets.
43 Separate OPAC record character set for ZOOM_record. yaz_record_render
44 allows a character set given as charset=from/opacfrom,to where 'from' is
45 the character set of a bibliographic record, 'opacfrom' is character set
46 of OPAC record and 'to' is the target character set.
50 yaz-client: show may XML format records. Command show followed by 'format'
51 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
54 src/stemmer.c: Avoid using unnamed union. It is not supported by some
57 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
60 Update yaz.spec to operate on both SLES11 / Centos 5.5.
62 RPM: Release includes 'indexdata' name. Use indexdata in release name so
63 this package can be distinguished from other vendors.
65 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
66 as determined by configure
68 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
70 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
71 returns no error and no record, the present request is considered
72 partial (only a subset of the records could be returned by backend), and
73 so it is appropriate to set Present Status to partial-4.
77 Move yaz-config man pages to section 1.
79 More documentation about SOLR.
81 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
82 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
83 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
84 peers on some Linux systems. However, in general that does not work
85 so YAZ can not rely on that to work. Debian changed behavior in this
86 respect from Debian lenny to Debian squeeze (still testing as of Oct
88 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
90 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
94 Fix yaz-config output: echo_source not set correctly by configure.
98 SOLR WebService support for yaz-client and ZOOM.
100 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
102 --- 4.0.12 2010/08/17
104 Z39.50 facet support. Facet specifications are passed for search in
105 other-information with ASN.1 as defined in facet.asn and OID
106 .10.1000.81.5 . Facets are expressed as an Attribute list as known
107 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
108 3 is limit (number of entries to get in response). yaz-ztest returns
109 dummy facets if a client asks for them.
111 --- 4.0.11 2010/07/09
113 CCL fixes: bug 2895 and bug 3539.
115 GR1-display: add comma in display - was removed by mistake in
118 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
120 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
122 --- 4.0.10 2010/06/18
124 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
125 result set from a connection. The result set will be on its own
126 thereafter; no operations on it will perform retrievals from a target.
127 Only cached copies are returned.
129 ZOOM C:fix case for HTTP servers responding with Connection:close.
130 Ensure that if there is a current task it is resumed (like fetching
131 more records in a result set) . Bug #3484.
133 PQF parser: use odr_atoi for Odr_int (not atoi)
135 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
136 values that contain any non-digits are treated as string attributes
137 (previously decoding only checked for leading character ([0-9]). PQF
138 encoding: attribute string values are not surrounded by double-quotes.
142 New utility for managing threads - thread_create.h.
144 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
145 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
146 but YAZ' implementation do.
148 Fixes for yaz_cond-functions on Windows 7.
150 DLL export more symbols.
152 zoomsh: show record do NOT render opac.
154 Remove *.la files from Debian and RPM packages.
158 Debian package libyaz-dev depends on libgnutls-dev again (was
159 removed in YAZ 4.0.6, but due to Libtool it is still needed
160 even though yaz-config do not list libgnutls libs).
162 ZOOM: Use only one WRBUF for returning string results for
163 ZOOM_resultset. Reduces memory usage for ZOOM in general.
165 ZOOM: ZOOM_connection do not use a shared pointer to
166 ZOOM_resultset after ZOOM_resultset is destructed by
167 user. Reverts to YAZ 4.0.4 behavior.
171 record-conv: fix problem with at least one XSL conversion -
172 due to probably incorrect usage of XML XSL documents.
176 Fix yaz-config for static mode and the use of SSL (gnutls).
180 Forward decl timeval struct in mutex.h and gettimeofday.h.
182 yaz-config: fix 'static' mode linking.
186 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
187 are wrappers for pthreads or Windows. For Windows these are put in
188 a separate DLL: yaz_cond4.
190 libyaz.la (whole source) is compiled with thread. If thread support
191 is enabled enabled, all source of YAZ is compiled with treading support.
192 This allows core utilities such as yaz_log to use thread facilities.
193 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
194 thread utilities. This commit moves mutex utilities (mutex.c) from
195 libyaz_server.la to libyaz.la.
197 yaz-json-parse displays leading text until error.
201 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
202 patch from Giannis Kosmas.
204 SRU: no longer URL encode SRU database. The URL for an SRU server is
205 a URL and such is alreeady encoded - at least when given with leading
206 http:// or https://. This reverts behavior to YAZ 3.0.50.
208 Support for new MARC XML notation TurboMARC which like MARCXML is a
209 complete representation of MARC/ISO2709.. This one, however, is more
210 compact and allows for faster processing with XSLT. TurboMARC can be
211 used in the marcdisp.h API, from the yaz-marcdump utility and from
214 yaz-ztest can be configured - via the database - to perform certain
215 delays when it performs operations search, present and single record
216 fetch. This allows testers to make yaz-ztest act as a real or even slow
217 Z39.50 server. Refer to the yaz-ztest man pages for details.
221 wrbuf_destroy allows NULL WRBUF passed to it.
223 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
225 Add ZOOM_connection_close.
227 No fixed size buffers for ZOOM shell - bug #3257.
229 tstodr: make it work on s390 platform.
231 New icu iterator-functions. The new icu_iter-functions makes it possible
232 to use ICU chains from many threads.
234 yaz-client: better syntax check for show command.
238 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
241 New simple local-file XML include facility which allows file glob-patterns.
242 Refer to yaz/xml_include.h.
244 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
247 ZOOM_record_get supports new parameter "format" which makes it format XML
250 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
251 JSONText in ECMA-262) is JSONValue, not JSONObject.
255 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
256 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
258 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
259 POSIX/Unix builds .so with major version 4.
261 Remove old LOG_-defines from log.h. They have been obsolete and
262 undefined by default for the last 5 years.
264 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
266 GFS: Remove socket (int *fd) from search_rr handler. The socket
267 descriptor ptr is a facility that allowed a search handler to supply
268 a socket which would serve as a callback - when search was complete.
269 This facility has now been in use for years.
271 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
272 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
273 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
274 returns 'const char *' rather than 'char *. The returned string is
275 read-only and should not be modified by applications. COMSTACK cs_close is
276 now a void function - it no longer returns int. No applications check for
277 the value and the implementations has always returned 0.
279 ZOOM: use size_t for scan hit counts and str size. Functions
280 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
281 occ (hit count) and len (string length) are now of type size_t pointer
282 rather than int pointer. This is to be able to represent large hit counts
283 and to also just to use the proper type for string length (strlen result).
285 New JSON parser. Refer to include/yaz/json.h .
287 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
288 Used to be int in some cases. Many wrbuf_-functions used to return an int
289 indicating some length.. These return values were never used. And so they
292 ODR: odr_malloc, odr_total now takes size_t for size.
294 clone_z_type: fix leak; occurred for encoding failures.
296 --- 3.0.52 2009/12/03
298 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
299 bug was introduced in 3.0.51.
301 --- 3.0.51 2009/12/02
303 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
305 tcpip comstack: fix leak for getaddrinfo.
307 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
308 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
309 Decoding of SRU "path" database is performed by private function
310 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
311 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
313 yaz-client: honor base command for SRU. Change when database setting
314 is applied for SRU and ensure it is kept when a connection is reset.
315 Change also the way errors are displayed or SRU (decoding of packages).
317 --- 3.0.50 2009/11/02
319 Add support for extra request / response data for SRU codecs and GFS.
320 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
321 for extra data response buffer and length. For the GFS, both request
322 and response data (XML) is carried in extra_args and extra_response_data
323 for the search handler. Patch by Ko van der Sloot.
325 ZOOM: For queries that cannot be converted to the specified rpnCharset,
326 ZOOM now returns a diagnostic on the client-side ('invalid query' /
327 10010). This fixes bug #2113.
329 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
330 cmdfile included a 'quit' command that would result in a memory violation.
332 --- 3.0.49 2009/10/01
334 Make a number of functions defined in xmlquery.c static. These have
335 never been declared in a public header file (yaz/xmlquery.h) and was
336 made public by mistake.
338 Improve speed of character conversions (iconv utilities). This makes
339 conversions from MARC-8 faster.
341 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
342 unless type desired is "raw". This will prevent type "xml" from
343 returning ISO2709 .. Which obviously can not be XML parsed.
345 Fix memory leak in ZOOM that would occur if option apdulog was used
346 on a re-used connection.
348 Frontend server logs HTTP requests.
350 Frontend server now sends Z39.50 close when it times out (sesssion has
351 been idle for too long). Versions 2.0.30 and earlier also sent close.
352 But due to a mistake this was disabled in all versions after that, i.e.
353 the server would just close the socket immediately.
355 yaz-client emits a better message when receiving an unrecognised
356 userInformationField.
358 Skip zero-length subfields when decoding ISO2709. This rare case happens
359 if a record has two FS characters in a sequence. Without this patch
360 there would be a reference beyond char array in using_code_len fragments
363 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
365 --- 3.0.48 2009/08/28
367 The show command offered by the zoomsh command now takes a 3d optional
368 parameter type which is what is passed to ZOOM_record. If the type
369 argument is omitted, "render" is used.
371 RPN to CQL conv may use USE string attributes (bug #2978).
373 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
375 --- 3.0.47 2009/07/08
377 Function yaz_xml2query allows a diagnostic element in the PQF XML
378 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
379 code and additional info respectively.
381 The BER BOOLEAN is now the integral type Odr_bool which still happens
382 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
383 typedef'd to Odr_int. This is still an integral 'int', but it may be
384 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
385 ASN-1 compiler as well as programs has been updated to use the new types.
387 --- 3.0.46 2009/06/08
389 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
390 only the bibliographic record was rendered. For type=opac, an OPAC
391 record is only returned if it is present.
393 iconv: small fix for encoding of advancegreek.
395 yaz-client: avoid double display of SRU/SRW records (bug #2798).
397 yaz-client: option auto_reconnect=on really reconnects.
399 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
401 server: avoid null ptr ref for for yaz_poll errors.
403 build: fix RPM build for RHEL 5.3.
405 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
407 --- 3.0.45 2009/03/31
409 Fixed bug #2709: TCP connect returns Invalid argument.
411 Fixed compilation for mingw.
413 Honor charset for raw records (ZOOM_record_get).
415 Fixed use of errno for threaded mode that was seen on Solaris 10.
417 Fixed argument passing with blanks in value for Windows Service.
419 Disable YAZ' own log rotate by default (no 1 GB limit).
420 The variable l_max_size which specifies the log file limit is set to 0
421 (DISABLED): This is due to the fact that YAZ is most often deployed using
422 logrotate. Also YAZ can not perform log rotate because of unsufficient
423 permissions (setuid).
425 --- 3.0.44 2009/02/17
427 List supported encodings in man page for yaz-iconv.
429 Fixed missing SSL libs for --libs output
431 Re-established OID record syntax application-xml. Nobody should use it
432 but we don't want to change soname because of this symbol being absent.
434 --- 3.0.42 2009/02/02
436 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
438 Added member named_result_sets for init handler struct for the GFS. This
439 allows a server to disable named result sets.
441 Removed OID record syntax application-xml.
443 Added support for rule-based transliterator for ICU wrapper of YAZ.
445 Fixed bug #1902: yaz-icu XML output.
447 Make YAZ checks Emacs friendly.
449 BITSTRING value shows value. Bug #2346.
451 ISO2709 decoding: skip control characters from indicator data.
453 Omit sort key by default in yaz-icu's output.
455 Allow combined single char options (again) for YAZ' options function.
457 Utility yaz-marcdump got option to display YAZ version (-V).
459 Allow YAZ to use ICU 3.4.
461 Added new ICU test case which illustrates removal of diacritics.
463 --- 3.0.41 2008/12/29
465 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
467 --- 3.0.40 2008/12/29
469 For configure, using option --without-xml2 also disables Libxslt/Libexslt
472 Fixed bug #2352: yaz-marcdump crashes for certain record.
474 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
476 Added support for Danmarc2 to UTF-8 conversion.
478 Added support for ISO5426 to UTF-8 conversion.
480 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
481 implementation version.
483 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
485 --- 3.0.38 2008/11/10
487 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
488 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
490 ZOOM C now interprets databaseName option for ZOOM connection as path
493 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
495 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
497 Dummy Libxml2 types no longer defined in headers of YAZ'.
499 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
502 --- 3.0.36 2008/09/26
504 Various ODR chapter fixes.
506 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
508 Added missing source for Windows compilation, mutex.c.
510 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
512 For SRU connections in ZOOM all records up to "count" are now fetched.
514 Fixed crash in generic frontend server (and yaz-ztest) which occurred
515 in Windows due to bad error handling for Libxml2.
517 Added facility for sending arbitrary records (ASN.1 any) using
518 ZOOM C's Extended service update. Patch by Sam Reynolds.
520 New options for ZOOM C's connection, logapdu which makes ZOOM log
523 --- 3.0.34 2008/06/18
525 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
527 --- 3.0.32 2008/06/12
529 Fixed memory violation that could occur when decoding UTF-8. This bug
530 was only present in 3.0.30 of YAZ.
532 --- 3.0.30 2008/06/06
534 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
535 GNU TLS is used by default (if found).
537 yaz-ztest returns OPAC records if a client asks for OPAC.
539 Improved speed of MARC-8 encoding.
541 Added support for lossy and loss-less MARC-8 encoding.
543 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
545 Added new Windows Service wrapper (sc).
547 yaz-client's itemorder command may now send a file.
549 Fixed yaz-marcdump to allow the use of NS prefix for record element.
551 Added new function yaz_log_xml_errors.
553 Allow (but warn) unknown XML attributes in MARCXML parsing.
555 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
557 The UTF-8 to MARC-8 conversion now uses a different set of characters
558 for Greek symbols. Bug #2120.
560 --- 3.0.26 2008/02/21
562 Added yaz_daemon (daemon.h).
564 Fixed bug #2068: pkg-config trouble
566 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
568 --- 3.0.24 2008/01/28
570 Document --with-xml2 option.
572 Added OPAC XML XSD (etc/opacxml.xsd).
574 Allow glob mask for name attribute in retrieval element for the
575 generic frontend server's retrieval facility.
577 Changed yaz_poll_poll to return yaz_poll_except for all returned events
578 except POLLIN/POLLOUT.
580 Fixed error handling in cs_listen. Bug #2037.
582 --- 3.0.22 2008/01/20
584 Fixed version in yaz/yaz-version.h.
586 Fixed bug #2027: Crash when closing connection.
588 Changed configure so that ICU support is only enabled if only ICU
589 and Libxml2 is available (because the ICU chain is XML based).
591 --- 3.0.20 2008/01/15
593 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
594 is built. Only this DLL depends on the ICU runtime.
596 yaz-ziffy is no longer part of YAZ. It is distributed separately by
597 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
599 Changed license of CCL module to 'Revised BSD'. After consultation with
600 remaining members of the original EUROPAGATE consortium, we are re-issuing
601 the CCL module without a separate license. The software was developed by
602 Index Data as part of a research project. The special license was included
603 to help feed usage information back to the project consortium to support
604 project evaluation. At this time, the project consortium has long-since
605 disbanded, and the majority of the original principals have retired. At the
606 same time, we have significantly modified the software during the following
607 years, to the point where very practically no original code remains. To
608 simplify re-use of the software, we have contacted those members of the
609 consortium who could be reached, and agreed to re-issue the module as a
610 proper part of the YAZ package.
612 Tcl scripts uses /usr/bin/tclsh as preferred shell.
614 CQL closer to being version 1.2 compliant. CQL also allows free-form
615 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
618 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
619 bug could make Extended services handling crash in the ZOOM layer. This
620 bug was only present in YAZ 3.0.18.
622 --- 3.0.18 2007/12/19
624 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
627 yaz-marcdump reads and writes collection wrapped records.
629 Handle OPAC for record conversion module.
631 Fixes for ICU wrapper.
633 Allow ICU libs to be controlled with --with-icu .
635 --- 3.0.16 2007/11/12
637 Added yaz_poll which is a wrapper for select/poll. When poll is available
638 and non-buggy, it is used, by yaz_poll . This allows more than 1024
639 sockets to be in use.
641 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
642 functionality through an XML based configuration (ICU chain). This system
643 is useful for search facilities such as Pazpar2 and Zebra that needs to
644 perform tokenization of indexed material. The ICU code in a separate
645 library libyaz3_icu.a.
647 Added HTTP tunnel facility for COMSTACK, bug #1752.
648 This is a facility that allows a Web proxy, such as squid, to tunnel
649 Z39.50 traffic. This facility is "transparent" to must applications
650 using YAZ. It's enabled by using pseudo transport connect: followed by
651 the proxy address, followed by command, then follwed by he regular
652 "virtual" addresss. For example,
653 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
655 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
657 --- 3.0.14 2007/09/21
659 Fixed bad memory reference in ZOOM_record - cuased by member not being
660 initialized. This was a problem only in YAZ 3.0.12.
662 Fixed bug in conversion from MARC to XML: Non-XML characters in control
663 fields were not removed.
665 Changed the way C code is generated from codetables.xml. Made a MARC-8
666 conversion trie for each characterSet section rather than codeTable.
667 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
668 of codetables.xml from Larry Dixson, LOC. Bug #1464.
670 --- 3.0.12 2007/09/12
672 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
673 from ZOOM_record_error).
675 ZOOM C function ZOOM_record_get returns record schema for type="schema".
677 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
679 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
681 Better SRW-to-Bib-1 diagnostic mapping.
683 ZOOM C and yaz-client announces SRU version 1.2 by default.
685 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
688 Fixed in yaz_sru_decode to allow other version than 1.1.
690 --- 3.0.10 2007/08/22
692 Added support for SRU scan for ZOOM.
694 Added support for the use of the older versions or Extended Service
695 Update in ZOOM. To faciliate this, an option "updateVersion" may be
696 set to the version , 1=first, 2=second, 3=third. The third version is
697 what ZOOM C has used so far. And that, obviously, is the default.
699 Added support for CCL queries in Z39.50 queries sent to the GFS (and
700 therefore in Zebra and in SimpleServer-based applications). The new
701 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
702 qualifier file used to transform incoming CCL queries into Type-1 RPN,
703 which is passed into the back-end search callback function.
705 Added support for HTTP Basic authentication in clients: the SRU/W
706 codec encodes the username/password elements of the PDU structure
707 appropriately, and these may be set using the "user" and "password"
708 options in ZOOM-C applications (the same options that are used for
709 Z39.50 authentication).
713 Fixed bug #1208: SSL appears to be broken in ZOOM.
715 Fixed bug #1206: Libxml2 include path weirdness.
717 Added oid_name_to_dotstring.
719 Allow elementSetName to be specified for ZOOM C record update.
721 Allow waitAction to be specified for ZOOM C based for Extended Services.
723 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
724 syntax OID. Bug introduced in YAZ 3 series.
726 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
730 Fixed bug #1157: yaz-client does not read .yazclientrc from current
731 directory. yaz-client now reads commands from file given by option -f
732 if specified; then tries to read .yazclientrc in current directory.
733 Failing that, it reads .yazclientrc from user's home directory.
735 Added support for correlationInfo Note and ID for Record Update via
738 Added yaz-client command querycharset which specifies character set for
739 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
740 (termListAndStartPoint).
742 Charset ISO5428:1984 is an alias for ISO5428-1984.
744 Implemented a way to perform scan in a result set using Z39.50. This
745 is achieved by attaching the result set name in the characterInfo
746 (type InternationalString) of OtherInformation in the Scan Request PDU.
747 The result set is identified in the otherinformation by the new OID:
748 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
749 This allows for scan in result set and faceted search . Zebra did some
750 of this in the APT term using attribute type 8 and value being result
751 set. Using the OtherInformation approach for this is cleaner and easier
752 to work with in proxies and the like. This facility can be used in
753 yaz-client using new command setscan which takes a result set as first
754 argument, start position (APT) as second.
756 Changed decoding of SRU XML packed records to deal with servers that
757 have recordData with XML data with multiple root nodes. Also make
758 comparison for recordPacking case insensitive. Again, one server
759 returns "XML" where others return "xml".
761 For SRU responses allow Content-Type application/xml as well as text/xml.
765 Fixed bug in character set conversion of BER strings. Bug introduced
770 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
772 For OID class, use oid_class consistently.
774 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
777 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
778 character set for bibliographic information interchange". By Giannis Kosmas.
780 Added documentation on new OID API.
784 Changes to generic frontend server interface: added new member
785 'query_charset' for bend_initrequest structure. A backend init handler
786 should set this member to its native character set for query terms.
787 When defined, the frontend server logic will announce this character set
788 to a client if the negotiationModel bit is set by the client. All server
789 implementors are encouraged to specify this. If a backend server does not
790 specify this a warning is issued using yaz_log(YLOG_WARN,..).
792 Added CCL utility to remove terms (stop words) from resulting RPN
793 tree. This is handled by functions with prefix ccl_stop_words_ .
795 New ZOOM C option, "rpnCharset", which allows client-side conversion of
796 terms in RPN queries.
798 Clean-up the CCL API. Moved some internal structures from ccl.h to
799 private header cclp.h. Changed ccl_parser_create so that a Bibset must
800 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
801 This is replaced by ccl_parser_find_str which takes a string instead.
803 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
804 libyaz.la is the core of YAZ except the generic frontend server and
805 does not depend on POSIX threads anymore. libyaz_server.la is the
806 generic frontend server facilities and uses POSIX thread functionality
807 if available. The libyaz.la no longer depends on POSIX threads because
808 the number of global structures is limited. NMEM no longer re-uses blocks
809 between threads ; it simply free's memory immediately but allocates in
810 "large" chunks as usual. We don't expect any performance penalties
811 because of this. The yaz_log system is still using a global log_level so
812 caution must be taken when modifying it with yaz_log_init_.. +
813 yaz_log_mask_str. This, however, should not cause any trouble because
814 these functions are called during initialization of application code
815 anyway. `yaz-config --libs server` returns libs for server applications;
816 `yaz-config --libs` returns libs for non-server applications.
818 New OID database - with public definitions in oid_db.h. Removed old OID
819 database including the head oid.h and definitions such as enum oid_value
820 and struct oident. The new OID database uses the same string names as
821 before but the 'protocol' is gone. There are now only two representations
822 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
823 converts from string to OID; functions with prefix yaz_oid_to_string
824 converts the other way.
826 Change to emit_term() in CQL-to-PQF query translation: when a term has
827 the /regexp relation modifier, do not process it for leading and
828 trailing "^" and "*", which have quite different meanings in regular
831 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
832 write handlers no longer carries a 'last' parameter. This will make
833 yaz_iconv flush "less" characters. A flush is performed by call to
834 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
836 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
837 removed, because function yaz_query_to_wrbuf does the same.
839 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
840 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
842 Deprecated MARC utility functions removed.
844 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
847 Branch split: YAZ_2_1_55_branch
849 --- 2.1.54 2007/03/16
851 Fix to ZOOM-C so that transparent reconnection is properly handled on
852 connections that are in asynchronous mode.
854 Fixed compilation on OpenBSD 4.0.
856 Large strings in GRS-1 records are now properly displayed in yaz-client.
858 Added character conversion support for "advancegreek"; based on patch from
861 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
862 sequence is met. Before the error was not set so it would be unknown.
864 Adjust yaz-marcdump MARC reader so that it skips until record separator
867 --- 2.1.52 2007/03/07
869 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
870 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
871 fd_set structure used as a bitmask for the FDs to be selected on.
873 Using ACX_PTHREAD macro to check for POSIX threads.
875 Fixed have-vsnprintf check.
877 --- 2.1.50 2007/02/23
879 Fixes for configure on BSD. Bug #900.
881 Added snprintf/vsnprintf wrappers for systems that don't have
882 limits (heavens forbid).
884 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
885 created before all previous tasks were completed and removed from the
886 task queue, the new task could be removed by a mistake.
888 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
890 Implemented pass-through CQL-to-PQF conversions. Bug #861.
892 Fixed bug #832: Problem with MARC/charset in yaz-client.
894 Fixed bug #668: save command line history for yaz-client.
896 Fixed bug #830: pkg-config support.
898 --- 2.1.48 2007/01/23
900 Extended ZOOM result set options with two options that may be read by
901 a client: resultSetStatus and presentStatus with values as specified for
903 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
905 Fixed bug #827: Using SSL fails on Debian etch.
907 Fixed bug #826: Weird looking chars for set of MARC records.
909 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
910 that is treated as an ItemOrder with itemRequest being an XML document
911 external. The value of "doc" is the content.
913 Extended the GFS search facility. New member of bend_search_rr
914 'estimated_hit_count' signals that hits is known to be an estmate
915 (higher or lower than real hit count). New member 'partial_resultset'
916 signals that the search was partial (hit count is lower or equal than
917 real hit count). For Z39.50, the information is stored in resultSetStatus
918 member of SearchResponse APDU. For SRU, the information is signalled
919 via SRU diagnostic 59: "Result set created with valid partial results
922 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
924 --- 2.1.46 2007/01/13
926 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
928 Added ZOOM_connection_peek_event.
930 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
931 the following new functions:
932 ZOOM_event_nonblock, ZOOM_connection_process,
933 ZOOM_connection_get_{socket,mask,timeout},
934 ZOOM_connection_fire_event_{timeout,socket}.
935 The existing blocking event handler, ZOOM_event, is a wrapper for the
936 + blocking ZOOM_event_sys_{poll,select}.
938 Implemented function ccl_xml_config which parses XML version of CCL
939 configuration (bug #798).
941 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
943 Added timings utility (yaz/timing.h)
945 --- 2.1.44 2007/01/03
947 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
950 Fixed bug #779: Rotation of apdu.log fails.
952 Fixed for character set conversions:
953 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
954 Honor G1 set in MARC-8 decoding.
956 --- 2.1.42 2006/12/17
958 Fixed bug #775: char conversion does not handle Alternative UTF-8
961 Implemented function yaz_marc_read_line which parses MARC line format
962 records. There is a wealth of formats out there. So far, this function
963 reads line records produced by yaz_marc_write_line.
965 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
966 more generic and easier to remember(!) options: -i format and -o format
967 which specifies input format and output format respectively - where
968 format is one of "marc", "marcxml", "line", "marcxchange".
970 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
971 does not print anything except warnings for records.
973 For yaz-marcdump, added support for MARC split into files (-s) with a given
976 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
977 spec, at http://www.loc.gov/standards/sru/record-update/
978 This has changed the binary layout of the following structs:
979 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
980 bend_update_rr . Patch by Ko van der Sloot.
982 Added GFS utility function bend_assoc_is_alive which returns 1 if
983 association is still alive (client is connected); 0 otherwise (client
984 closed connection). This allows busy servers to stop working for
987 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
988 been a separate piece of software. This version of ziffy has been modified
989 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
991 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
993 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
994 Client code may now interrogate options such as "init_opt_sort" to
995 find out whether the server claims to support various options.
997 --- 2.1.40 2006/11/27
999 Added utilities yaz_{set,get}_esn to set/get element set name from
1002 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1003 of YAZ and has been so since YAZ 2.1.10.
1005 Implemented ZOOM_record_error which returns error information for
1006 record (surrogate diagnostic).
1008 --- 2.1.38 2006/10/31
1010 Updates for SRU Update by Ko van der Sloot:
1011 1. Changed name from "operation" to "action"
1012 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1013 versions in the code, marked as 'backward compatible'.
1014 3. Added diagnostics for SRU Update.
1016 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1018 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1020 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1022 For GFS, fixed problem with SRU diagnostic 'First record position out of
1023 range' being issued for 0 hits.
1025 zoomtst10 part of Windows Build.
1027 --- 2.1.36 2006/10/13
1029 Implemented yaz_filepath_comp which splits a path into file path
1030 components (required by Zebra 2.0.3+).
1032 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1033 BSD inspired license until now so this should not have any real impact on
1034 anybody. See http://www.opensource.org/licenses/bsd-license.php
1036 Fixed bug #687: Missing log lines.
1038 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1041 Fixed bug #689: SRU diagnostics to be added.
1043 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1044 whether a connection is idle (no more work do do).
1046 --- 2.1.34 2006/10/04
1048 Change type of optval from long to int for invocation of setsockopt with
1049 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1051 Added support for specifying the max log file size for the Generic
1052 Frontend Server. The size is given with option -r.
1054 --- 2.1.32 2006/09/21
1056 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1058 --- 2.1.30 2006/09/17
1060 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1063 Fixed bug in Generic Frontend Server that could cause a server to stop
1064 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1066 For the generic frontend server, the maximum record size is used as maximum
1067 size of incoming packages (SRU + Z39.50). The value until was previously
1068 only used in Z39.50 Init negotiation and, later, in a session controlled
1069 sizes of records returned. This is controlled using -k option. It can be
1070 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1072 --- 2.1.28 2006/09/04
1074 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1077 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1079 New option for yaz-marcdump -lpos=value which allows setting a portion
1080 of MARC header to a certain value.
1082 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1084 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1085 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1087 --- 2.1.26 2006/08/15
1089 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1092 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1094 --- 2.1.24 2006/08/08
1096 Fixed MARC ISO2709 encoding routines to deal with character set
1099 Minor changes to GFS logging. Database included in search request log
1102 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1103 cached/multiple records.
1105 Shared libraries are built by default on Unix+configure.
1107 Changed cql2pqf transformation to use a different evaluation order. The
1108 new order is: always, relation, structure, position, truncation, index
1109 and relationModifier. Old order was: always, relation, relationModifier,
1110 structure, index, position, truncation. Note that the the latter ones
1111 override former ones for identical attributes.. The new scheme means that
1112 it is possible to override any existing attribute with a relationModifier.
1113 And also that it is possible to override everything for the index rule
1114 (except the ones listed in relationModifier). No order is perfect but this
1115 one, we believe, covers more real cases.. The "always" should have been
1116 called "default", since the attributes there can be overridden with all
1119 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1120 compilation phase, but also for yaz-config --cflags output. This allows
1121 us to have public headers with Libxml2 stuff in them . It should also,
1122 eventually, make Libxml2 checks redundant in packages using YAZ, such
1125 --- 2.1.22 2006/06/15
1127 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1128 stored in uri, message and details.. Previously diagnostics were stored
1129 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1130 compatibility.. but he's probably the only one affected, so.
1132 Added support for CCL, compiled on the client side, in ZOOM-C. This
1133 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1134 input; the resulting query objects can be used for for searching with
1135 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1137 YAZ' configure searches for OpenSSL by default.
1139 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1140 SL_CTX_use_certificate_file. See
1141 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1142 for more info. Thanks to Ko van der Sloot.
1144 --- 2.1.20 2006/06/02
1146 Bug #600: SRU GET, POST support for yaz-client. Introduced
1147 command 'sru' which selects method SOAP/GET/POST.
1149 Allow missingValueAction to be specified for the sortspec string -
1150 function yaz_sort_spec. By default, the missing value action is null.
1151 Use ! to specify "abort". Use = followed by stringvalue to specify default
1154 Ensured that Present-handler (if defined) is called in GFS before any call to
1155 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1156 searchRetrieve requests.
1158 Documentation for YAZ is now based on the Docbook XML/XSLT using
1159 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1160 is no longer depending on jade/openjade or docbook-to-man scripts.
1161 PDF is no longer part of the distribution - but can optionally be
1162 made using DSSSL/jadetex or FOP.
1164 Added retrieval handling support in Generic Frontend Server to support
1165 conversion between MARC/XML as well as XSLTtransforms. See
1166 etc/yazgfs.xml for an example.
1168 Added Authentication support to Generic Frontend Server in SRU
1169 mode. Authentication using HTTP Basic is supported, as is the use
1170 of 'x-username' and 'x-password' parameters in the request itself.
1172 Added support for a new character set MARC8s identical to MARC8 except
1173 that it converts combined characters to single Unicode characters in the
1174 Latin-1 range (when possible).
1176 --- 2.1.18 2006/04/24
1178 ASN.1 compiler 0.4: generates brief Doxygen file header for
1179 generated .h/.c files.
1181 Utility yaz_iconv now supports conversion to MARC-8.
1183 New facilities for the MARC module. The reading - and writing of
1184 content are separate methods for the yaz_marc_t handle. The following
1185 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1186 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1187 format). Write functions have prefix yaz_marc_write_.. The existing
1188 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1189 available. Removed support for OAI-MARC and simplexml (not the
1190 simplexml from PHP5).
1192 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1193 to be returned for this connection.
1195 --- 2.1.16 2006/03/31
1197 Allow multiple languages and charsets to be specified with
1198 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1199 negcharset iso-8859-1,utf-8
1201 Translation of proximity nodes from CQL into PQF now works.
1203 Moved to automake 1.8, 1.9.
1205 Added function yaz_log_set_handler which allows a log handler to be
1206 installed. This handler will be called for all log messages. Output
1207 to file is also produced; but that can be disabled by passing NULL
1208 fname to yaz_log_init_file.
1210 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1212 For SRW (including GFS), accept application/soap+xml as content-type
1215 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1216 produces NO stylesheet reference even if a default stylesheet is specified
1219 --- 2.1.14 2006/03/14
1221 Updated Windows package to include yazd.dll + yazd.lib for the
1222 Development component.
1224 If the environment variable YAZ_LOG is set, then it is used as a
1225 string indicating the default level of logging to use if not
1226 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1227 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1228 used as before. So, for example, to omit warnings from YAZ logging,
1229 export YAZ_LOG=-warn
1231 cql_transform() now map structure and other attributes before indexes,
1232 so that index-specific structures and other attributes can override
1233 defaults. So now a combination of mapping specifications such as:
1235 index.dc.date = 1=date-modified 4=5
1236 does the right thing.
1238 cql_transform() now also respects the "always" mapping specification,
1239 which establishes an initial set of attributes to be used for all
1240 terms except where overridden by more specific attributes associated
1241 with the index, relation or modifier.
1243 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1244 which mode to use; one of "post", "get" or "soap" (SRW, default).
1246 Fixes for yaz_iconv routines: changed trie-based character set conversions
1247 to use only non-negative values for bit fields due to Sun's C compiler not
1248 supporting negative values.
1250 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1251 sequences where not read correctly. Fix by Rustam Usmanov.
1253 Updated win/makefile to use options, settings which makes things
1254 compile with VS C 2005.
1256 --- 2.1.12 2006/02/01
1258 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1260 In ZOOM socket code, use select instead of poll on MacOSX.
1262 ZOOM-C now support client-side compilation of CQL into RPN that is
1263 sent to the server, enabling CQL to be used against all Z39.50
1264 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1265 ZOOM_query object, and submit it using ZOOM_connection_search().
1266 The CQL-to-RPN translation uses a configuration file, the name of
1267 which must be specified in the Connection's "cqlfile" option.
1269 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1270 function, which takes as its start-term parameter a ZOOM_query object
1271 (which may have had either CQL or RPN set into it).
1274 --- 2.1.10 2005/11/29
1276 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1277 GFS to support this as well. Backend handler, bend_srw_update, does the
1278 update work. Code contributed by Ko van der Sloot.
1280 Allow retrieval of Search Result-1 information in ZOOM by the use of
1281 options that are attached to a result set. ZOOM documentation updated
1284 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1285 UTF-8 conversion. Patch by Raj Patel.
1287 Added option -m to GFS to control formatting of timestamps in log file.
1289 Added 'exit' as synonym for 'quit' in yaz-client
1291 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1292 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1293 for the new members. Patch by Ko van der Sloot.
1295 Added support for SRU POST. It is supported for content-type
1296 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1298 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1299 Instead make the library libyaz.la multi-threaded. Threading as a whole
1300 can still be disabled by configure option --disable-threads. Previosly,
1301 with older GLIBCs there were problems with MT libs under Apache. This
1302 has now been fixed a long time ago.
1304 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1307 CQL module modified to be case insensitive for relations/indexes/operations.
1309 Fixed bug in CQL transform code: incorrect value relationModifieder
1312 Added 'show all' command for yaz-client which retrieves all results
1315 Added new yaz-client, xmles, which takes a (private) OID and
1316 a document to be sent as an extended service request.
1318 Describe new yaz-client commands wait_response and set_auto_wait.
1320 Increase TCP/IP listener backlog from 3 (which I am guessing was
1321 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1322 that the socket will queue as many incoming connections as it's able
1323 to handle ongoing connections. In other words, it will never now
1324 refuse a connection that it would be able to handle merely because
1325 it's not got around to accepting() enough of the pending connections
1326 yet. This is the behaviour anyway under Linux, where the listen()
1327 argument is ignored; but not under BSD and on systems such as
1328 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1329 YAZ-based servers should now be uniform across operating systems in
1332 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1333 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1334 This allows yaz-marcdump to read large MARC batches (>2 GB).
1336 Modified all YAZ source files - except the source which is auto-generated
1337 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1340 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1341 corresponding to the existing *_setl() function. These allow option
1342 values containing arbitrary valuues.
1344 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1345 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1346 except that it returns an indicator of whether or not the sort
1347 criterion was accepted (0 for OK, -1 for invalid).
1349 --- 2.1.8 2005/06/07
1351 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1352 MARC output rather than returning "new" buffer.
1354 yaz-client warns about unknown init options.
1356 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1358 --- 2.1.6 2005/05/24
1360 Added support for SRW sort in Generic Frontend Server. Patch
1361 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1362 sortKeys - or NULL if none is provided.
1364 Fixed bug #307: It was impossible to specify indefinite/no timeout
1365 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1368 Added support for multiple languages and charsets to be specified in
1369 ZOOM. Each charset/language is separated by a blank. If negotiation is
1370 in effect in init-response, Option
1371 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1372 Code based on patch by Vasiliy Osadchuk.
1374 Fixed bug #306: infinite recursion that occurred when calling
1375 yaz_log_level_init as the first call (before other log level or
1378 Fixed bug in scan handling in front end server: if preferred-Position-In-
1379 Response was non-present, a NULL pointer referece was performed.
1381 --- 2.1.4 2005/04/26
1383 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1384 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1385 now defined for all those error codes. So instead of putting 109 in
1386 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1387 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1389 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1392 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1394 Program yaz-client now exits and produces an error message if multiple
1395 Z39.50 servers are specified on the command line (none or one allowed
1398 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1401 --- 2.1.2 2005/03/16
1403 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1405 Fixed bug #272: Preserve spacing for CCL terms.
1407 --- 2.1.0 2005/03/14
1409 Added support for virtual hosts and multiple backend servers for
1410 the YAZ frontend server. The configution is XML based and
1411 support specificition of CQL to RPN mappings and explain information.
1412 See section "Virtual Hosts" in the YAZ manual.
1414 Extended OPAC display utility. OPAC display utility renders
1415 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1416 to supplement yaz_marc_decode_wrbuf.
1418 Fixed a bug in MARC decoder that could caused it to crash for some
1419 invalid MARC records. More diagnostics and warnings where added in
1420 XML output (warnings, etc are stored in comments).
1422 --- 2.0.34 2005/02/08
1424 Fixes for UNIX domain sockets. Bug #261.
1426 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1428 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1429 Added yaz_marc_subfield_str which defines subfield lead string which is
1430 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1431 yaz_marc_endline_str which defines end of fields string used in
1432 YAZ_MARC_LINE format. Default string is newline.
1434 Experimental support for MarcXChange. This format can be produced
1435 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1436 http://www.bs.dk/standards/MarcXchange.xsd
1438 Added yaz-client commands scansize that sets maximum number of
1439 entries to be returned by scan.
1441 --- 2.0.32 2005/01/11
1443 Added support for SRW scan in yaz-client and Generic Frontend Server.
1445 * Added whereInList member to SRW Scan Term.
1447 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1449 Fixed NMEM system to return aligned blocks on the smallest boundaries
1450 that are suitably aligned for all possible types on the particular
1451 architecture YAZ is being built for.
1453 --- 2.0.30 2005/01/04
1455 Fixed numerious warnings that was issued with newer versions of GCC.
1457 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1458 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1461 Make YAZ Generic Frontend Server slightly faster.
1463 Enhance (and reduce) logging for Generic Frontend Server.
1465 Revert YAZ log system so that it flushes every write operation
1466 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1468 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1469 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1470 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1471 will effectively disable old definitions.
1473 --- 2.0.28 2004/11/09
1475 Added yaz_log_time_format which specifies log format using
1478 Added yaz_log_module_level which returns mask for a module. Value
1479 is non-zero mask a if module is enabled; zero if disabled.
1481 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1482 in include/yaz/cql.h.
1484 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1486 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1488 Fixed bug #172: RPM builds does not enable SSL.
1490 Doxyfile.in part of dist. Doxyfile generated by configure.
1492 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1493 are given and the corresponding component does not exist.
1495 Extend CCL documentation in YAZ reference. Describe r=r.
1497 --- 2.0.26 2004/10/01
1499 Fixed MARC->MARCXML conversion to properly deal with
1500 fields, subfields, indicators having non-ASCII characters.
1502 Fixed MARC->MARCXML conversion so that ASCII control characters
1503 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1506 Added YAZ GFS support for conversion from Z39.50 surrogate
1507 diagnostics to SRW surrogate diagnostics.
1509 Bug fix: YAZ GFS did not return schema in explainResponse.
1511 --- 2.0.25 2004/09/30
1513 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1514 now converts recordSchema to elementSetName as well as schema URI.
1516 Fixed bug in COMSTACK that prevented HTTP request packages from being
1519 --- 2.0.24 2004/09/29
1521 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1522 does not require white-space before and after the dash in a range, e.g.
1523 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1526 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1527 due to new GCC removing "redundant" code.
1529 Added yaz-client commands scanpos and scanstep that sets preferred
1530 position and step-size for scan.
1532 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1534 Added CCL utility ccl_qual_buf which parses one or more CCL
1535 spec lines in a buffer.
1537 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1538 of name and value - ignoring empty lines and comments.
1540 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1542 Added odr_get_element_path which returns current element path for an
1543 ODR handle. This utility is useful in error handling or user-defined
1546 Added ODR_PRINT utility odr_set_stream which is is a more generic
1547 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1548 to a write function and pointer to close function. The close function - if
1549 non-NULL - will be called during odr_destroy.
1551 Fixed bug in CCL parser where truncation char was not removed from
1552 right side when truncation=both was in effect.
1554 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1557 --- 2.0.23 2004/08/11
1559 Fix buffer overrun in CQL parser when dealing with proximity (%).
1561 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1562 to UTF-8/UCS conversion is now only based on codetables.xml.
1564 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1566 --- 2.0.22 2004/08/06
1568 Add support for more "commit changes" in ZOOM (uses Extended Services).
1570 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1573 Yet another small fix for configure of SSL.
1575 --- 2.0.21 2004/05/14
1577 Fix SSL libs for configure when --with-openssl=DIR is given.
1579 --- 2.0.20 2004/05/10
1581 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1583 SSL comstack now uses yaz.pem certificate file on server side
1584 by default. Certificate filename can be configured by calling
1585 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1587 Fix bug regarding multiple calls to ZOOM_connection_connect.
1589 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1591 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1592 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1594 ZOOM now allows inspection of X509 peer certificate for verification.
1595 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1597 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1598 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1599 as "modular" but it simplifies things.
1601 Added cs_get_peer_certificate to that returns peer X509 PEM.
1603 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1604 NULL if SSL is unavailable.
1606 Documentation about MARC decoding tools.
1608 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1610 --- 2.0.19 2004/03/30
1612 Rename CHANGELOG to NEWS to follow GNU style packing.
1614 Fix bug with missing initialization of member in init_diagnostics.
1615 This bug affects threaded version of GFS server.
1617 --- 2.0.18 2004/03/20
1619 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1622 Ensure zlib.dll is packed with Windows install.
1624 --- 2.0.17 2004/03/17
1626 Fix encoding of xsd:string to use text instead of CDATA.
1628 Fix endless loop in CQL parser with unbalanced ".
1630 Use a more compact way to store MARC-8 conversion tables.
1632 --- 2.0.16 2004/03/16 Debian only
1634 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1637 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1642 --- 2.0.15 2004/03/01
1644 Another fix for decoding of XML packed records.
1646 --- 2.0.14 2004/02/25
1648 Fixes for Chunked encoding. White space not ignored after length spec.
1650 Update NS and use default NS for SRW diagnostic elements.
1652 --- 2.0.13 2004/02/23
1654 Implement ZOOM_resultset_cache_reset which resets record cache.
1656 Implement ZOOM_resultset_sort which sorts a result set.
1658 Implement chunked HTTP transfer.
1660 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1662 --- 2.0.12 2004/02/16
1664 Added member 'schema' to bend_explain_rr structure so that backend
1665 can specify explain record identifier. Defaults to Zeerex 2.0.
1667 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1669 --- 2.0.11 2004/02/16
1671 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1674 Added init command for yaz-client which sends "extra" init request.
1676 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1677 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1679 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1681 Make ZOOM error code for "invalid query".
1683 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1685 --- 2.0.10 2004/02/05
1687 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1690 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1692 Added option -p <file> to make Generic Frontend Server to write PID file.
1694 Added option -D to put Generic Frontend Server in background on its own.
1696 Make ZOOM C recognize option "password". If unset, "pass" is used
1697 (for backwards compatibility).
1699 Fixed a bug in Generic Frontend Server that could make it crash if a
1700 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1703 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1704 Must be issued before open, in order to be in effect.
1706 --- 2.0.9-6 2004/01/12 Debian/Windows
1708 Make the SRU server more picky WRT unknown params, etc.
1710 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1712 New YAZ client command, options, that sets Z39.50 options.
1714 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1715 options from a string of tokens (one token for each option bit).
1717 Update SRW diagnostic code messages.
1719 --- 2.0.9-5 2004/01/07 Debian/Windows
1721 Handle user defined stylesheet for SRW/SRU.
1723 --- 2.0.9-4 2004/01/06 Debian/Windows
1725 Fix bug in decoding of Content-Length.
1727 --- 2.0.9-3 2004/01/06 Debian/Windows
1729 Fix a bug with decoding of XML packed records.
1731 --- 2.0.9-2 2004/01/05 Debian only
1733 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1735 Fix bug in SRW/SRU diagnostics decoding.
1737 --- 2.0.9 2004/01/05
1739 Fixed bug in Generic Frontend Server which could drop records exceeding
1740 preferred message size. Reported and fixed by Irina Dijour.
1742 Fixed calculation of package size for structured records in Generic
1743 Frontend Server. Reported and fixed by Irina Dijour.
1745 Fixed namespace for SRW/SRU diagnostics.
1747 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1749 --- 2.0.8 2003/12/22
1751 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1752 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1755 CQL changes to reflect recent changes to the specification:
1756 * Documentation talks about context sets instead of index sets.
1757 * Documentation talks about indexes instead of qualifiers.
1758 * The CQL-to-PQF transformer's configuration file now uses
1759 "index.set.name = <attributes>" instead of the old form
1760 "qualifier.set.name = <attributes>". (Both forms are still
1761 understood but the latter is deprecated.)
1762 * CQL terms with no explicit index specified are now interpreted as
1763 cql.serverChoice instead of srw.serverChoice (which of course
1764 behaves exactly the same.)
1766 --- 2.0.7 2003/12/16
1768 MARC conversion can now generate ISO2709 output in another
1769 character set. yaz-marcdump uses this facility if you invoke it
1772 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1773 functions from there can be used from C++.
1775 --- 2.0.6 2003/12/04
1777 Frontend server now transfers memory from decoded packages to stream
1780 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1781 references to show up.
1783 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1784 the ZOOM Abstract API. The older names for the same options are still
1785 also supported for the benefit of old applications.
1787 ZOOM-C supports "implementationId" and "implementationVersion" options
1788 to go along with "implementationName". These allow the user code to
1789 specify identification strings to be sent to servers.
1790 Add OID for the new ExtLite attribute set.
1792 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1793 as requested/supplid by Ere Maijala <ere@atp.fi>
1795 For generic frontend server, reverse the order of
1796 "toolkit-supplied / application-supplied" strings sent as implementationId,
1797 Name and Version. Also, remove the spaces around the slash. This brings
1798 the GFS in line with the behaviour of ZOOM-C on the client side.
1800 Add function ZOOM_scanset_display_term.
1802 yaz-client shows scan displayTerm if present.
1804 Utility yaz-iconv is now installed by default along with the man page
1807 Extend configure check for OpenSSL to use pkg-config where available (such
1810 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1811 server to specify uid/gid/mask for socket using the format
1812 unix:[user=uid,][group=gid,][umask=mask,]file=path
1813 If file= is omitted the existing format is assumed, e.g.
1815 in which case the mask is 0666 (rw for everybody).
1817 Major restructure of YAZ source. All source in libyaz is in src directory.
1818 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1819 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1821 Added man page for utility yaz-marcdump (used to be called marcdump).
1822 yaz-marcdump is installed by 'make install'.
1824 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1825 of incoming package failed.
1827 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1829 Change prototype of odr_perror: add const to message string.
1831 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1833 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1834 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1835 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1836 DNS lookup. There should not be any compatibility problems with this
1837 assuming that blocking=1 or 0 is used.
1839 Fix bad reference in UNIX comstack in function cs_addrstr.
1841 Fix for compilation on AIX.
1843 The generic front-end server (server/seshigh.c) now supports returning
1844 Init diagnostics to the client in User-information-field, in
1845 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1848 --- 2.0.4 2003/09/04
1850 Allow any CQL relation (not just all,any,exact,scr).
1852 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1853 that features the same UI.
1855 Implemented command update0 in YAZ client which is equivalent to
1856 update but uses old of Ext Update ASN.1.
1858 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1859 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1860 Previously no OID was used for this info.
1862 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1863 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1864 returns 'malformed search term' otherwise.
1866 SortResponse member resultCount now set to NULL in sort handler of
1869 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1872 Add three new utility functions for translating OIDs between various
1873 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1874 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1875 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1876 char *oid_to_dotstring(const int *oid, char *oidbuf);
1877 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1879 Reverted modifications for ES Update definition for z_IU0Update
1880 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1881 is back to YAZ 2.0.2.
1883 String value attributes for CCL parser.
1885 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1886 which their FirstSearch server returns in Init responses, sometimes
1887 carrying useful diagnostic information when Init fails. This has the
1888 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1889 "z39.50/oclcui.asn", where its definition is somewhat different from
1890 what OCLC document on their web-site, as required to interoperate with
1893 Support for anonymous authentication in yaz-client. Use the command
1896 * Fix the OID of the Index Data-local "admin" Extended Service from
1897 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1898 the 1000, which indicates a locally-defined OID, was a mistake.
1900 --- 2.0.3 2003/06/20
1902 Fix CCL directive @case handling so that it affects string match for
1903 both CCL keywords and qualifiers.
1905 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1906 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1907 Decoder has been updated with ASN.1 changes as listed in
1908 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1909 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1910 z_IUUpdate, remains unchanged.
1912 ZOOM_record_get may now return a record in a specific character set.
1913 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1914 "from" is the character set of record as returned by target. "to" is
1915 the character set to be returned. If omitted, "to" is UTF-8.
1917 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1919 New ODR utility, odr_getelement, which returns name of element for
1920 which encoding/decoding failed.
1922 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1923 in cases where a required element was omitted.
1925 Bug fix: some MARC8 sequences were not converted.
1927 New ZOOM option "step" which specifies number of records to be
1928 retrieved in one chunk. Used in conjunction with "start" and "count".
1930 SRW support for yaz-client. Use scheme http: to use it, e.g.
1933 yaz-client no longer does (un)intelligent character set conversions
1934 by default. Can be enabled with charset and marc_charset commands.
1936 xmalloc trace fix for 64-bit systems such as DEC alpha.
1938 Solaris 2.6 compile fix.
1940 New function, cql_strerror() translates SRW error codes, as returned
1941 by cql_transform_error(), into human-readable English strings. Used
1942 in yaz-client diagnostics when appropriate.
1944 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1945 converts it into a type-1 query which is sent to the server. This
1946 makes CQL available for use with all Z-servers, as opposed to the tiny
1947 minority that can handle CQL queries themselves.
1949 --- 2.0.2 2003/04/28
1951 New Debian package layout similar to the Redhat Package layout.
1953 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1954 and search result respectively.
1956 --- 2.0.1 2003/04/25
1958 Redhat package is now several packages: libyaz (runtime libraries),
1959 libyaz-devel (development and documentation, and yaz (utility programs).
1960 Package spec file by Morten Bogeskov.
1962 New member 'schema' in struct bend_fetch_rr which the name of requested
1963 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1964 handler MAY set this to reflect the schema of the returned record.
1966 New member 'display_term' in struct scan_entry. GFS now sets member entries
1967 and allocates scan entries to be filled by user scan handler. In previous
1968 version, entries member was allocated by the scan handler. That still works,
1969 but the GFS will ignore member display_term - assuming it was NOT set by
1970 the handler. The fact that the GFS now allocates the entries both allows
1971 for new members and makes a scan handler easier to write.
1973 Fix CQL lex buffer overflow.
1975 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1976 SRU default recordPacking is string.
1978 SRU protocol support for frontend server.
1980 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1982 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1984 Added scan for the ZOOM shell (zoomsh).
1988 * String Identifers for Schemas (Amendment 5).
1989 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1990 Old definition for schema
1991 Odr_oid *schema; /* OPT */
1996 Z_InternationalString *uri;
1997 #define Z_Schema_oid 1
1998 #define Z_Schema_uri 2
2001 * resultCount parameter to Sort Response (Amendment 1).
2002 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2004 Support for SRW 1.0 over HTTP. This is an optional feature and
2005 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2008 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2009 on the same port. SRW SearchRetrieveRequests are mapped
2010 to bend_init,bend_search,bend_fetch,bend_close.
2012 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2014 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2015 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2017 ZOOM connections are SRW based if schem http is used for hostname
2018 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2019 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2021 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2022 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2023 distance=n, order=true/false, relation=le, prox unit=word. If
2024 n is omitted, distance 1 is used.
2026 Fixed problem with C compiler include path in wrong order.
2028 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2029 on Solaris. Patch from Ko van der Sloot.
2031 New MARC decode API. All new functions operate on a yaz_marc_t
2032 handle. The most important new functions are: yaz_marc_create,
2033 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2034 decode and destroy respectively. Decoder can produce formats
2035 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2036 include/yaz/marcdisp.h.
2038 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2039 to UTF-8, UCS-32, wchar_t or Latin-1.
2041 * Prototypes for yaz_iconv_-functions moved to separate header
2042 include/yaz/yaz-iconv.h.
2044 Make a few private functions 'static' in unix.c. This prevents
2045 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2047 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2048 are set when Init Response is received.
2050 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2051 but returns diagnostic set as well.
2053 New function yaz_strerror which is a portable wrapper for
2054 strerror/strerror_r/GetLastMessage.
2056 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2057 is returned for MARC. If type is "oai", then OAI MARC is returned.
2059 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2062 --- 1.9.2 2002/11/26
2064 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2066 Fix bad race conditions on SIGTERM and terminate gracefully in
2069 Move retrieval (data1) module to Zebra since nobody seems to be
2072 Add GRS-1 render for ZOOM using same format as yaz-client.
2074 --- 1.9.1 2002/10/05
2076 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2078 Fix broken ESpec handling in data1 module.
2080 SGML reader parses comments and makes them part of the data1 tree.
2082 Added several type casts so that YAZ compiles as C++ code.
2084 ZOOM didn't handle PDU encoding failures properly.
2086 Added more Bib-1 diagnostics (approved extensions).
2088 GNU configure: better check for iconv.
2090 More portable use of accept, getpeername. Check for socklen_t. Use
2091 int/size_t if socklen_t is not defined.
2095 PQF parser rejects bad queries - including those with extra
2096 characters in them. PQF parser used to silently ignore that.
2097 Cleaner API for PQF added, which allows you to get detailed
2098 error information for bad queries (see yaz/pquery.h).
2100 Fixed bug in ZOOM_record_get for type "database".
2102 Implemented mini iconv library supporting conversions between
2103 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2105 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2107 --- 1.8.9 2002/08/20
2109 Fixed ZOOM C record cache so that preferredRecordSyntax and
2110 elementSetName is used to check for already fetched records.
2112 --- 1.8.8 2002/08/02
2114 Added three members in bend_initrequest structure to facilitate
2115 character set negotiation.
2117 Fixed a bug in frontend server that could cause indefinite
2118 loops under rare conditions.
2120 Revised character set utilities (charneg.h) so that encoding
2121 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2123 For PQF, directive @term <type> sets term type for Scan/Search.
2124 Here <type> is general, string, numeric, null. The term type
2125 is inherited - just like @attr.
2127 New call odr_set_charset that sets character set conversion for
2128 international-strings on a ODR stream. Prototype is:
2129 int odr_set_charset(ODR o, const char *to, const char *from);
2130 The InternationalString is still represented as C string in YAZ
2131 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2132 won't). On the protocol level, you can use any encoding.
2134 Support for UNIX sockets in ZOOM.
2136 Solaris recv sometimes returns errno == ENOENT. It is treated as
2137 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2139 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2140 both client and server. Code by Morten Bogeskov.
2142 --- 1.8.7 2002/05/22
2144 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2145 that they can be used directly from Visual Basic. You must recompile
2146 your windows APP if you're using ZOOM.
2148 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2149 Commands "lang" and "charset" sets language and character set respectively.
2150 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2151 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2153 Attributes from multiple CCL fields may be OR'ed rather than merged
2154 using directive "@field or". Fields are still merged by default -
2155 equivalent to "@field merge".
2157 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2160 Fixed bug in zget for parameter ExtendedServicesResponse.
2164 --- 1.8.6 2002/03/25
2166 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2168 Client displays USR.1:SearchResult-1 (hits per term).
2170 Additional Search Info for search in Generic Frontend Server.
2172 Fixed CCL parsing of "field=s".
2174 WIN32 installer - using the excellent NSIS software from nullsoft.
2176 Fixed CCL parsing of "field = - <number>".
2178 Added function yaz_marc_decode that decodes MARC for line mode
2179 display or XML (similar to that used by JZKit).
2181 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2182 Z39.50. But ISO/ILL was, however.
2184 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2185 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2187 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2188 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2190 --- 1.8.5 2002/02/03
2192 New YAZ client features: Command completion and new commands:
2193 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2194 Code provided by Jacob Poulsen.
2196 New call oid_trav, that visits all registered OIDs via callback.
2198 Function ZOOM_record_get now returns const char pointer rather than
2199 void pointer. It saves a lot of type casts.
2201 For YAZ client, command "auth" now allows you to set authentication
2202 in IdPass style. It is enabled when three tokens are given - order
2203 is user, group and password.
2205 Fix memory leaks in MARC record handling for ZOOM.
2207 New option for YAZ client, -k <kilobytes> that sets
2208 maximum record size. Similar to -k option for generic frontend
2209 server and yaz-ztest.
2211 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2213 Prefix query parser reports "fail" when bad attribute set is given.
2215 Fix in MARC decoder. Proximity logging. Fix for attribute set
2216 in scan handler for server. Patches by Shigeru Ishida.
2218 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2221 Configure option --with-openssl=<dir> now works when a directory is
2222 specified. Patch provided by Morten Bogeskov.
2224 New option for YAZ client, -u <auth>, that sets authentication.
2226 ZOOM fix: error information was sometimes "missing", since error
2227 was cleared/reset too when it shouldn't.
2229 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2231 --- 1.8.4 2002/01/04
2233 Scan for ZOOM API. New object ZOOM_scanset. New functions
2234 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2235 ZOOM_scanset_destroy.
2237 New ZOOM function, ZOOM_connection_last_event, that returns type
2238 of last event (such as "receive data", "send data", "apdu received",
2241 New ZOOM option, schema, that specifies schema for retrieval.
2243 New CCL feature. Qualifiers can be aliases for one or more
2244 other qualifiers (if more than one is given, OR is used).
2246 ZOOM uses named result sets if target supports it.
2248 Two new YAZ client commands: . (dot, which sources a script of YAZ
2249 client commands), and ! (to execute shell command.). Implemented
2252 Working on Debian packages.
2254 --- 1.8.3 2001/11/19
2256 YAZ client enables named result sets only if target supports it.
2258 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2260 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2261 with key="host" to get same result.
2263 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2264 Function Z3950_resultset_record(s) returns references to records
2265 "owned" by resultset. To become owner use Z3950_record_clone.
2267 Function z_ext_record handles Extended Services. Thanks to
2270 --- 1.8.2 2001/11/12
2272 CCL Parser fix: ignore token comma when dealing with and-lists.
2274 Documentation updates for COMSTACK.
2276 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2277 Changed prototype Z3950_records. For some functions, int parameters
2278 were changed to size_t.
2280 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2283 New MARC decode/display function, marc_display_exl, which properly rejects
2284 non-ISO2709 records. YAZ client uses it.
2286 --- 1.8.1 2001/10/29
2288 Fix bug: local attribute set wasn't set correctly in PQF strings.
2292 * Old Z39.50 codecs no longer supported.
2294 Added ZOOM C binding. See http://zoom.z3950.org/
2296 Renamed states for COMSTACKs to avoid confusion with events.
2298 Implemented cs_look and proper cs_rcvconnect.
2300 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2302 Configure detects POSIX threads on OpenBSD.
2304 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2305 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2307 When error is returned from present handler, non-surrogate diagnostic
2308 is returned in present response (and fetch handler is no longer called).
2310 * Minor adjustments to pquery parser (PQF). Token characters may be
2311 escaped by using backslash (C-style).
2313 PQF parser allows string attribute values to be specified. For @attr,
2314 non-numeric characters after the equal-sign are treated as strings
2315 (e.g. @attr 9=title).
2317 CCL trunction character may be defined (@truncation in file)
2319 * function zget_ExtendedServicesRequest sets waitAction to
2320 waitIfPossible (was wait).
2322 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2325 CCL operator names may be set in field definition files (CCL_bibset).
2326 See ccl/bib1 for an example.
2328 Fixes in ASN.1 compiler for C++ compatibility.
2330 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2331 and "op_or" to avoid conflict with C++.
2333 Fixed problem with GNU readline detection on Redhat 7.0.
2335 Added step-size for Scan backend handler.
2337 Fixed bug that made the frontend server crash when no attribute
2338 set was specified for scan.
2340 Front-end server automatically switches to original working directory
2341 when installed as an NT service. Previously -w had to be specified to
2344 Added extended attributes for retrieval module (data1), so that data1
2345 records carry d1_readXML/SGML attributes. d1_read also supports
2346 null-data rules ( <tag/>)
2348 On UNIX when POSIX threads are available, a separate library libyazthread
2349 is created. Programmers should link with that library and the yaz library
2350 when using threads. The reason for the split was that some applications
2351 on Linux, such as Apache, doesn't work well when using shared objects that
2354 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2355 (or any frontend server) in SSL mode by specifying ssl: followed by
2356 address. Only tested on UNIX.
2358 Added feature for CCL module. Virtual structure s=al or s=ol generates
2359 and-list and or-list respectively instead of phrase search.
2363 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2364 log_mask_str. This was done to avoid name conflicts with other libraries
2365 (such as other PHP extensions).
2367 Added raw OID member for preferred record syntax (request_format_raw)
2368 and returned record syntax (output_format_raw) for backend fetch method.
2370 Config file yaz-config now accepts options so that it returns specific
2371 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2373 Shared library support for UNIX using GNU libtool.
2375 * Modified backend interface. Request/Response struct's replaced by
2376 one read/write C struct. For example bend_fetchrequest and
2377 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2378 Every handler - even search has to be registered in bend_init
2379 handler. This means that the YAZ library no longer refers to
2380 external functions and it makes it possible to make the whole
2381 thing a single DLL/SO.
2383 Added Segment handler for backend server.
2385 Added Zmbol/Zebra administrative functions to YAZ client.
2387 Threaded frontend server on UNIX (when POSIX Threads are available).
2388 Starting the server with option -T enables multi-threading.
2392 Added configure option --enable-comp/disable-comp to control use
2393 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2394 located in sub directory asn.
2396 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2397 in ${exec_prefix}/bin along with the other programs yaz-client and
2400 GNU automake used to maintain makefiles.
2402 Added several OID's.
2404 Changed retrieval module so that we can load records with no abstract
2405 syntax defined. Tagpaths in these records are fully composed of string
2408 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2412 On UNIX, the generated makefile now supports a proper 'make install'.
2413 The prefix can be set via GNU configure to set the install location
2414 (default is /usr/local).
2416 * YAZ programs client and ztest were renamed to yaz-client and
2417 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2418 locations, such as /usr/bin,/usr/local/bin,etc.
2420 * YAZ Header files were moved from include to include/yaz. YAZ Header
2421 files are referred to as include <yaz/log.h> rather than <log.h>.
2422 The YAZ include path (-I ..) is therefore the same as before. Programmers
2423 should update their #include statements or use -Ipath/include/yaz
2424 instead. The main motivation for doing this change is that YAZ header files
2425 can be installed in "standard" locations /usr/include,/usr/local/include
2426 without introducing conflicts, since ALL YAZ header files are stored
2427 in subdirectory yaz (under /usr/include for example).
2429 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2430 rather than project/workspace files. We switched because project files
2431 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2434 Changed name of logging function, logf, to yaz_log, to prevent name
2435 clash with some math-log functions. The YAZ header log.h defines logf
2436 to yaz_log (#define) so there should be no incompatibilities by this
2439 Added bend_start/bend_stop handlers for server. These handler are
2440 called on start/stop of server. For windows they are called whenever
2441 a service is started/stopped.
2443 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2444 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2445 in util/yc.tcl. The auto-generated C code structures are, in a few
2446 cases, incompatible with the old decoders. There are differences in the
2447 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2448 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2449 The preprocessor variable ASN_COMPILED is defined when the compiled
2450 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2451 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2452 wish to use the old encoders/decoders you can specify --disable-yc
2455 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2456 version so that it supports both new - and old version of DB Update
2458 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2459 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2460 change. The name parameter can be set to 0 in which no name is specified
2461 for the construction. The macros odr_implicit and odr_explicit sets name
2462 parameter to zero for the construction involved. New macros
2463 odr_implicit_tag and odr_explicit_tag are similar to the others,
2464 except that a name parameter is added. For programmers' that don't use
2465 ODR they probably only need to change the call to z_APDU and z_External.
2467 Added access control facility by interfacing the TCP wrapper library.
2468 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2469 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2470 name of the daemon and enables the access control as specified in
2471 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2473 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2474 den Dool <H.M.vdnDool@kub.nl>.
2476 Added reference ID parameter to most functions in server API - refer
2477 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2479 Changed name of ccl library to libccl.a (was ccl.a).
2481 Fixed bug in decoder for Explain (Category TargetInfo).
2483 Added support for GNU readline in client. Thanks to Jacob Poulsen
2484 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2486 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2487 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2488 IMPLEMENTATION! This change was made to the development version before
2489 the ZIG decided to retract the amendment. If any users MUST be
2490 compatible with the original Update definition, PLEASE CONTACT US, and
2491 we will include a separate definition corresponding to the old Update
2492 ES. Note that because of the change to the ASN.1 of the
2493 TaskPackageRecordStructure we cannot define a single structure that
2494 will support both versions.
2496 * Added const modifier to buffer parameter for some ODR/BER encoding
2497 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2498 completeWAIS, odr_dumpBER.
2500 Fixed bug in client.c which caused a crash when a scanResponse didn't
2501 contain positionOfTerm.
2503 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2504 * will cause an error in a client if a non-YAZ target sends both a
2505 * list of Scan entries and non-surrogate diagnostics.
2507 Retrieval module enhancements. Tag sets may be typed in the reference
2508 to it. From the .abs-file the "tagset" directive takes a third optional
2509 integer type for the tag set referenced. From a .tag-file the "include"
2510 directive takes a third optional type as well. The old "type" directive
2511 in the tag set itself is still recognized but acts as the default type
2514 Backend interface change. Individual Scan terms returned from bend_scan
2515 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2516 in include/backend.h.
2518 Retrieval module enhancements. Multiple tag sets and attribute sets may
2519 be specified in abstract syntax specs. Revised the error/warning for
2520 logging messages reported by the retrieval module when reading the
2523 Object Identifier system (oid_..) changed. The API is backwards
2524 compatible but the oid-routines now allocates new OID's when needed.
2525 Raw OID's may be specified in oid_getvalbyname.
2527 YAZ now uses GNU configure to generate Makefile(s).
2529 * Minor changes in some of the member names of DeleteResultSetRequest and
2530 DeleteResultSetResponse. See include/proto.h.
2532 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2533 and added member 'languages' in TargetInfo (which was missing).
2535 Changed the way attribute sets are handled in the retrieval
2536 module. These are now cached, just like the abstract syntaxes
2539 Changed YAZ so that it links with compiled ASN.1.
2541 Added Explain-schema definitions and mapping routines. The following
2542 Explain categories have been implemented: AttributeDetails,
2543 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2545 Fixed minor bug in Windows version of Server Library.
2547 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2549 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2551 Added EXTERNAL: UNIverse Resource Report (non-standard).
2553 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2554 ENUMERATED and SET OF.
2556 * Added 'const' to some of the char pointer arguments for the
2557 functions, data1_read_node, data1_getelementbytagname,
2558 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2561 Fixed bug in data1_insert_taggeddata - the last_child member of
2562 parent wasn't initialised.
2564 * Changed data1_read_record and data1_read_node so that the supplied
2565 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2566 doesn't refer to any parts of the "SGML"-buffer.
2568 Fixed bug in server library (Windows version of statserv_remove).
2570 * Changed code so that it compiles as C++. The type definition
2571 of Odr_fun which is a member of Odr_arm was changed. The result is,
2572 that an explicit typecast is needed for the fun pointer when
2573 using Odr_arm - as in:
2574 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2576 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2578 Implemented the new structured date and time definition as approved
2579 by the ZIG. Added schemaId element to the specificTag in Espec-1
2580 (also approved at the last ZIG). Thanks to RVDM.
2582 Added some Object identifiers (RVDM).
2584 Changed the Update Extended Service (RVDM).
2586 Added command "refid" to client which specifies referenceId for
2587 the following requests.
2589 Implemented extended service handling for server. See ztest.c
2590 for an example as well as backend.h. New handlers are registerd
2591 in the Init handler.
2593 * Changed interface for sort in server.
2595 Added new members to statserv_options_block. It allows a server
2596 to read options from another source than just the command line. Thanks
2597 to Charles Woodfield.
2599 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2600 renamed to zboolean. Some C++ compilers complained about the name.
2602 Minor changes to gils.abs. Added index 's' (sort) on title
2603 and date/time-last-modified.
2605 --- 1.4pl2 1998/1/30
2607 Fixed bug in server library regarding inetd mode (-i). This bug
2608 was introduced by release 1.4.
2610 --- 1.4pl1 1998/1/29
2612 Added sort facility in client and backend server interface.
2614 Fixed problem with dependencies in Makefile(s).
2616 Fixed bugs for encoders/decoders of extended services and
2619 Implemented sub-tree feature for schemas. Sub-trees are
2620 referenced in *.abs-files. See explain.abs for an example
2621 of the use of this feature.
2623 Modified bib1.att; local attributes for ANY didn't include
2624 ANY itself (only affects use of the retrieval module).
2626 Fixed bug in plain SGML reader in function data1_read_node:
2627 tags with prefix "var" was incorrectly interpreted as variants.
2629 Added feature "sub-schemas" to enable references to - and definitions
2630 of - group of elements.
2632 * Removed member parent from type data1_element (in data1.h).
2634 Implemented function odr_nullval() that returns the value of
2637 * Removed member num_children from data1_node (in data1.h).
2639 Made NT service interface part of the server library. The
2640 function statserv_main uses the NT service when required and
2641 calls the statserv_start / statserv_close routines.
2643 Routine zget_SearchRequest and zget_PresentRequest fills
2644 resultSetName/Id member with "default" instead of "Default".
2646 Fixed memory leak in server. Request queue member wasn't freed.
2648 Fixed nmem_exit so that memory is freed.
2652 Revised the CCL parser utility to be thread safe.
2654 Added function, oid_ent_to_oid, to replace the function
2655 oid_getoidbyent, which is not thread safe.
2657 * Added nmem_init and nmem_exit to initialize and release
2658 NMEM resources. Function nmem_init should be called once in the
2659 initial thread before NMEM/ODR is used. statserv.c and client.c
2660 have been changed accordingly. The change was necessary to make
2661 NMEM thread safe. The NMEM memory pool is shared amongst threads
2662 in a process. Unix-based applications will still work fine without
2665 Added NT Services interface for the the Z39.50 (statserv) Server.
2666 Refer to the ztest.c source on the usage.
2668 Windows 95/NT port using MSVC5.0. Project files are included in the
2671 * Defined new 'global' handle for the retrieval (data1) system. The
2672 new handled, data1_handle, describes the state of the data1 system.
2673 This handle is passed as first argument to virtually all
2674 data1 related routines. The functions data1_create and data1_destroy
2675 creates and destroys a data1 handle respectively.
2677 Added ODR encode stream member to all backend request structures
2678 init, search, scan etc. This stream should be used to allocate all
2679 memory used for the response when thread safe operation is needed.
2681 Changed the comstack utility, cs_addstr, to be thread safe. The
2682 returned hostname string returned by the function is now part the
2685 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2686 function. The cs_straddr takes a COMSTACK handle as argument, so this
2687 function must be used after cs_create and before bind/connect.
2688 This function is thread safe.
2690 Moved test server to 'ztest' directory - generic server code still
2691 in 'server' directory.
2693 Made prefix query (pquery.c) utility thread safe.
2695 Added new function modifier YAZ_EXPORT to 'export' public DLL
2696 functions when using windows (see include/yconfig.h).
2698 Added definitions to the OID database (util/oid.c) (RVDM).
2700 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2702 Added call to ccl_rpn_delete in client program.
2704 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2705 release of RPN structure.
2707 Added support for C++, headers uses extern "C" for public definitions.
2708 With input from RVDM.
2710 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2711 Thanks to Ronald van der Meer (RVDM).
2713 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2715 Added support for private extensions to the OID database
2716 (oid_setprivateoids()). Thanks to RVDM.
2718 Added optional, physical ANY (key replication)
2720 Fixed null-reference problem in GRS-1 output filter.
2722 Proximity operator added to Prefix Query Format (PQF).
2724 In test client command "base" accepts multiple databases.
2726 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2730 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2732 Smallish bug-fixes in the new encoders/decoders (explain).
2734 Bug fixed in DeleteRequest.
2736 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2738 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2740 Added SOIF syntax (using private OID for now) to retrieval module and client.
2742 Added Update extended service.
2744 Added SearchResult-1 additional info structure.
2746 Added optional CCL (ISO8777) interpreter as separate module. Available
2749 --- 1.2 1996/6/10 (1st anniversary release)
2751 Added Summary record syntax. Lightly tested.
2753 Added OPAC record syntax. Untested.
2755 Added ResourceReport service encoders/decoders. Untested.
2757 Fixed bug in z_Unit - wrong tagging on unitSystem.
2759 Fixed bug in the DiagRecs decoder.
2761 Added options for max PDU size and session timeout to frontend-server.
2763 Added documentation of query-language parsers and other supporting utilities.
2765 [frontend-server] Added Attribute set to the bend_scanrequest API.
2767 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2768 surrogate diagnostics were generated.
2770 [retrieval] Allow multiple local values for attribute.
2772 [retrieval] Allow multiple attributes per element in .abs files. index type.
2774 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2776 --- 1.1pl2 1996/4/10
2778 Minor changes, mostly specific to Zebra's requirements (retrieval)
2782 Repaired bug in frontend server when running multiple listening
2783 endpoints in dynamic mode.
2785 z_External() now won't break if a known, ASN.1 value comes encapsulated
2786 in an octet-string. The value will pass through unmodified in an Odr_oct.
2788 Added a bit of code to the demo client to decode & display
2789 ASN.1-structured records represented in the octet-aligned branch of
2790 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2792 Added z_ext_getentbyref() to the ASN module. Doc updated.
2794 * Completed the SCAN definition in the ASN module. This may break SCAN
2795 code based on older YAZ-versions at compile-time. The fix is easy -
2798 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2799 under the SCAN definition. Remember to initialize this, server-people.
2801 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2802 that this does not extend to ODR and ASN.
2804 Comstack allows insertion of established socket (primarily for
2805 inetd-operation of servers). Doc updated.
2807 Front-end server can now start from the inetd in TCP mode. Doc
2810 --- 1.0pl4 1996/1/24
2814 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2815 the rank and record number.
2817 Adjustments to the frontend server.
2819 Fixed diagnostic BER dumper. It ignored the file argument.
2823 Various changes to retrieval module.
2825 Changed the union discriminators of the protocol files from enums to
2826 ints paired with #defines.
2828 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2831 *Changed operator in the RPN structure to 'roperator', again to avoid a
2834 Fixed problems in Explain decoders/encoders.
2836 --- 1.0pl2 1995/12/6
2838 Memory bug in log module fixed.
2840 --- 1.0pl1 1995/12/5
2842 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2844 Bug in Explain DatabaseInfo module fixed.
2846 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2850 The shift to v1.0 signals that we now consider the *core* functionality
2851 of YAZ reasonably stable (the core being more or less equivalent to
2852 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2853 tested (Explain not at all - though that will happen soonish).
2855 Minor changes to code to support Windows port.
2857 Various minor changes after we're getting to use GRS-1 & co. more.
2859 Added Espec-1 format.
2861 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2862 of the protocol and it cannot be selected when encoding (maps into 'string'
2863 when decoding). Needed to talk to some servers.
2865 Demo client can request simple element set names.
2867 Added Diagnostic Format encoders/decoders.
2869 Added simple Close handling to frontend server (no hooks for resource
2870 reporting yet), and demonstration client.
2872 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2874 --- 1.0b3 1995/08/24
2876 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2877 handled incorrectly when records were requested in the searchResponse. This
2878 will only affect you if you use the frontend-server.
2880 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2881 Test-client will ask for and print GRS1. Ztest will return dummy records
2884 Added Explain encoders/decoders to the service-level API. Untested.
2886 Added Extended Services: Item Order encoders and decoders to the Service-
2887 level API. Untested. We could use a recent copy of the pertinent bits
2888 of the ILL protocol to add those bits.
2890 Added diagnostic format 1 encoders/decoders to the service-level API.
2893 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2894 odr_cons.c, which causes a more correct output.
2896 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2897 was always set to 0 when no records were requested in the searchRequest.
2899 * Added better external-handling. This shouldn't harm old code that
2900 *encodes* externals. It can break code that looks for a
2901 'single-ASN1-type' representation, since those types that are known
2902 are now decoded immediately. Look at the SUTRS sample code in
2903 seshigh.c and client.c. Documentation updated.
2905 Handling of structured records in bend_fetchresponse. Length -1 marks
2906 structured record, type is deduced from format field.
2908 --- 1.0b2 1995/06/27
2909 Fairly quick maintenance release to add SUTRS support.
2911 Fixed handling of SUTRS records in the demonstration client.
2913 * Added format field to the bend_fetchrequest and bend_fetchresponce
2914 structures of the backend API (frontend server). When the record is
2915 returned, the value of the format field is mapped to an OID. The
2916 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2917 of the record. The special value VAL_NONE in the bend_request means
2918 that no specific format was requested by the client. Documentation
2919 updated accordingly. Test server (ztest) will return a fixed dummy
2920 SUTRS record if your client requests SUTRS.
2922 Documentation updated accordingly.
2924 You can now set external libraries and RANLIB support in the top-level
2928 First public release.
