3 Add -lCrun when linking with ICU on Solaris.
5 More quicks character set conversions for OPAC records.
9 fix problem with record_render: records were converted (character set
10 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
14 SRU: add methods for handling DADS SRU-proxy facets.
16 Separate OPAC record character set for ZOOM_record. yaz_record_render
17 allows a character set given as charset=from/opacfrom,to where 'from' is
18 the character set of a bibliographic record, 'opacfrom' is character set
19 of OPAC record and 'to' is the target character set.
23 yaz-client: show may XML format records. Command show followed by 'format'
24 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
27 src/stemmer.c: Avoid using unnamed union. It is not supported by some
30 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
33 Update yaz.spec to operate on both SLES11 / Centos 5.5.
35 RPM: Release includes 'indexdata' name. Use indexdata in release name so
36 this package can be distinguished from other vendors.
38 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
39 as determined by configure
41 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
43 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
44 returns no error and no record, the present request is considered
45 partial (only a subset of the records could be returned by backend), and
46 so it is appropriate to set Present Status to partial-4.
50 Move yaz-config man pages to section 1.
52 More documentation about SOLR.
54 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
55 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
56 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
57 peers on some Linux systems. However, in general that does not work
58 so YAZ can not rely on that to work. Debian changed behavior in this
59 respect from Debian lenny to Debian squeeze (still testing as of Oct
61 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
63 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
67 Fix yaz-config output: echo_source not set correctly by configure.
71 SOLR WebService support for yaz-client and ZOOM.
73 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
77 Z39.50 facet support. Facet specifications are passed for search in
78 other-information with ASN.1 as defined in facet.asn and OID
79 .10.1000.81.5 . Facets are expressed as an Attribute list as known
80 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
81 3 is limit (number of entries to get in response). yaz-ztest returns
82 dummy facets if a client asks for them.
86 CCL fixes: bug 2895 and bug 3539.
88 GR1-display: add comma in display - was removed by mistake in
91 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
93 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
97 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
98 result set from a connection. The result set will be on its own
99 thereafter; no operations on it will perform retrievals from a target.
100 Only cached copies are returned.
102 ZOOM C:fix case for HTTP servers responding with Connection:close.
103 Ensure that if there is a current task it is resumed (like fetching
104 more records in a result set) . Bug #3484.
106 PQF parser: use odr_atoi for Odr_int (not atoi)
108 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
109 values that contain any non-digits are treated as string attributes
110 (previously decoding only checked for leading character ([0-9]). PQF
111 encoding: attribute string values are not surrounded by double-quotes.
115 New utility for managing threads - thread_create.h.
117 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
118 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
119 but YAZ' implementation do.
121 Fixes for yaz_cond-functions on Windows 7.
123 DLL export more symbols.
125 zoomsh: show record do NOT render opac.
127 Remove *.la files from Debian and RPM packages.
131 Debian package libyaz-dev depends on libgnutls-dev again (was
132 removed in YAZ 4.0.6, but due to Libtool it is still needed
133 even though yaz-config do not list libgnutls libs).
135 ZOOM: Use only one WRBUF for returning string results for
136 ZOOM_resultset. Reduces memory usage for ZOOM in general.
138 ZOOM: ZOOM_connection do not use a shared pointer to
139 ZOOM_resultset after ZOOM_resultset is destructed by
140 user. Reverts to YAZ 4.0.4 behavior.
144 record-conv: fix problem with at least one XSL conversion -
145 due to probably incorrect usage of XML XSL documents.
149 Fix yaz-config for static mode and the use of SSL (gnutls).
153 Forward decl timeval struct in mutex.h and gettimeofday.h.
155 yaz-config: fix 'static' mode linking.
159 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
160 are wrappers for pthreads or Windows. For Windows these are put in
161 a separate DLL: yaz_cond4.
163 libyaz.la (whole source) is compiled with thread. If thread support
164 is enabled enabled, all source of YAZ is compiled with treading support.
165 This allows core utilities such as yaz_log to use thread facilities.
166 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
167 thread utilities. This commit moves mutex utilities (mutex.c) from
168 libyaz_server.la to libyaz.la.
170 yaz-json-parse displays leading text until error.
174 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
175 patch from Giannis Kosmas.
177 SRU: no longer URL encode SRU database. The URL for an SRU server is
178 a URL and such is alreeady encoded - at least when given with leading
179 http:// or https://. This reverts behavior to YAZ 3.0.50.
181 Support for new MARC XML notation TurboMARC which like MARCXML is a
182 complete representation of MARC/ISO2709.. This one, however, is more
183 compact and allows for faster processing with XSLT. TurboMARC can be
184 used in the marcdisp.h API, from the yaz-marcdump utility and from
187 yaz-ztest can be configured - via the database - to perform certain
188 delays when it performs operations search, present and single record
189 fetch. This allows testers to make yaz-ztest act as a real or even slow
190 Z39.50 server. Refer to the yaz-ztest man pages for details.
194 wrbuf_destroy allows NULL WRBUF passed to it.
196 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
198 Add ZOOM_connection_close.
200 No fixed size buffers for ZOOM shell - bug #3257.
202 tstodr: make it work on s390 platform.
204 New icu iterator-functions. The new icu_iter-functions makes it possible
205 to use ICU chains from many threads.
207 yaz-client: better syntax check for show command.
211 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
214 New simple local-file XML include facility which allows file glob-patterns.
215 Refer to yaz/xml_include.h.
217 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
220 ZOOM_record_get supports new parameter "format" which makes it format XML
223 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
224 JSONText in ECMA-262) is JSONValue, not JSONObject.
228 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
229 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
231 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
232 POSIX/Unix builds .so with major version 4.
234 Remove old LOG_-defines from log.h. They have been obsolete and
235 undefined by default for the last 5 years.
237 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
239 GFS: Remove socket (int *fd) from search_rr handler. The socket
240 descriptor ptr is a facility that allowed a search handler to supply
241 a socket which would serve as a callback - when search was complete.
242 This facility has now been in use for years.
244 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
245 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
246 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
247 returns 'const char *' rather than 'char *. The returned string is
248 read-only and should not be modified by applications. COMSTACK cs_close is
249 now a void function - it no longer returns int. No applications check for
250 the value and the implementations has always returned 0.
252 ZOOM: use size_t for scan hit counts and str size. Functions
253 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
254 occ (hit count) and len (string length) are now of type size_t pointer
255 rather than int pointer. This is to be able to represent large hit counts
256 and to also just to use the proper type for string length (strlen result).
258 New JSON parser. Refer to include/yaz/json.h .
260 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
261 Used to be int in some cases. Many wrbuf_-functions used to return an int
262 indicating some length.. These return values were never used. And so they
265 ODR: odr_malloc, odr_total now takes size_t for size.
267 clone_z_type: fix leak; occurred for encoding failures.
269 --- 3.0.52 2009/12/03
271 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
272 bug was introduced in 3.0.51.
274 --- 3.0.51 2009/12/02
276 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
278 tcpip comstack: fix leak for getaddrinfo.
280 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
281 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
282 Decoding of SRU "path" database is performed by private function
283 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
284 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
286 yaz-client: honor base command for SRU. Change when database setting
287 is applied for SRU and ensure it is kept when a connection is reset.
288 Change also the way errors are displayed or SRU (decoding of packages).
290 --- 3.0.50 2009/11/02
292 Add support for extra request / response data for SRU codecs and GFS.
293 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
294 for extra data response buffer and length. For the GFS, both request
295 and response data (XML) is carried in extra_args and extra_response_data
296 for the search handler. Patch by Ko van der Sloot.
298 ZOOM: For queries that cannot be converted to the specified rpnCharset,
299 ZOOM now returns a diagnostic on the client-side ('invalid query' /
300 10010). This fixes bug #2113.
302 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
303 cmdfile included a 'quit' command that would result in a memory violation.
305 --- 3.0.49 2009/10/01
307 Make a number of functions defined in xmlquery.c static. These have
308 never been declared in a public header file (yaz/xmlquery.h) and was
309 made public by mistake.
311 Improve speed of character conversions (iconv utilities). This makes
312 conversions from MARC-8 faster.
314 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
315 unless type desired is "raw". This will prevent type "xml" from
316 returning ISO2709 .. Which obviously can not be XML parsed.
318 Fix memory leak in ZOOM that would occur if option apdulog was used
319 on a re-used connection.
321 Frontend server logs HTTP requests.
323 Frontend server now sends Z39.50 close when it times out (sesssion has
324 been idle for too long). Versions 2.0.30 and earlier also sent close.
325 But due to a mistake this was disabled in all versions after that, i.e.
326 the server would just close the socket immediately.
328 yaz-client emits a better message when receiving an unrecognised
329 userInformationField.
331 Skip zero-length subfields when decoding ISO2709. This rare case happens
332 if a record has two FS characters in a sequence. Without this patch
333 there would be a reference beyond char array in using_code_len fragments
336 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
338 --- 3.0.48 2009/08/28
340 The show command offered by the zoomsh command now takes a 3d optional
341 parameter type which is what is passed to ZOOM_record. If the type
342 argument is omitted, "render" is used.
344 RPN to CQL conv may use USE string attributes (bug #2978).
346 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
348 --- 3.0.47 2009/07/08
350 Function yaz_xml2query allows a diagnostic element in the PQF XML
351 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
352 code and additional info respectively.
354 The BER BOOLEAN is now the integral type Odr_bool which still happens
355 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
356 typedef'd to Odr_int. This is still an integral 'int', but it may be
357 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
358 ASN-1 compiler as well as programs has been updated to use the new types.
360 --- 3.0.46 2009/06/08
362 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
363 only the bibliographic record was rendered. For type=opac, an OPAC
364 record is only returned if it is present.
366 iconv: small fix for encoding of advancegreek.
368 yaz-client: avoid double display of SRU/SRW records (bug #2798).
370 yaz-client: option auto_reconnect=on really reconnects.
372 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
374 server: avoid null ptr ref for for yaz_poll errors.
376 build: fix RPM build for RHEL 5.3.
378 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
380 --- 3.0.45 2009/03/31
382 Fixed bug #2709: TCP connect returns Invalid argument.
384 Fixed compilation for mingw.
386 Honor charset for raw records (ZOOM_record_get).
388 Fixed use of errno for threaded mode that was seen on Solaris 10.
390 Fixed argument passing with blanks in value for Windows Service.
392 Disable YAZ' own log rotate by default (no 1 GB limit).
393 The variable l_max_size which specifies the log file limit is set to 0
394 (DISABLED): This is due to the fact that YAZ is most often deployed using
395 logrotate. Also YAZ can not perform log rotate because of unsufficient
396 permissions (setuid).
398 --- 3.0.44 2009/02/17
400 List supported encodings in man page for yaz-iconv.
402 Fixed missing SSL libs for --libs output
404 Re-established OID record syntax application-xml. Nobody should use it
405 but we don't want to change soname because of this symbol being absent.
407 --- 3.0.42 2009/02/02
409 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
411 Added member named_result_sets for init handler struct for the GFS. This
412 allows a server to disable named result sets.
414 Removed OID record syntax application-xml.
416 Added support for rule-based transliterator for ICU wrapper of YAZ.
418 Fixed bug #1902: yaz-icu XML output.
420 Make YAZ checks Emacs friendly.
422 BITSTRING value shows value. Bug #2346.
424 ISO2709 decoding: skip control characters from indicator data.
426 Omit sort key by default in yaz-icu's output.
428 Allow combined single char options (again) for YAZ' options function.
430 Utility yaz-marcdump got option to display YAZ version (-V).
432 Allow YAZ to use ICU 3.4.
434 Added new ICU test case which illustrates removal of diacritics.
436 --- 3.0.41 2008/12/29
438 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
440 --- 3.0.40 2008/12/29
442 For configure, using option --without-xml2 also disables Libxslt/Libexslt
445 Fixed bug #2352: yaz-marcdump crashes for certain record.
447 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
449 Added support for Danmarc2 to UTF-8 conversion.
451 Added support for ISO5426 to UTF-8 conversion.
453 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
454 implementation version.
456 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
458 --- 3.0.38 2008/11/10
460 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
461 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
463 ZOOM C now interprets databaseName option for ZOOM connection as path
466 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
468 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
470 Dummy Libxml2 types no longer defined in headers of YAZ'.
472 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
475 --- 3.0.36 2008/09/26
477 Various ODR chapter fixes.
479 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
481 Added missing source for Windows compilation, mutex.c.
483 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
485 For SRU connections in ZOOM all records up to "count" are now fetched.
487 Fixed crash in generic frontend server (and yaz-ztest) which occurred
488 in Windows due to bad error handling for Libxml2.
490 Added facility for sending arbitrary records (ASN.1 any) using
491 ZOOM C's Extended service update. Patch by Sam Reynolds.
493 New options for ZOOM C's connection, logapdu which makes ZOOM log
496 --- 3.0.34 2008/06/18
498 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
500 --- 3.0.32 2008/06/12
502 Fixed memory violation that could occur when decoding UTF-8. This bug
503 was only present in 3.0.30 of YAZ.
505 --- 3.0.30 2008/06/06
507 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
508 GNU TLS is used by default (if found).
510 yaz-ztest returns OPAC records if a client asks for OPAC.
512 Improved speed of MARC-8 encoding.
514 Added support for lossy and loss-less MARC-8 encoding.
516 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
518 Added new Windows Service wrapper (sc).
520 yaz-client's itemorder command may now send a file.
522 Fixed yaz-marcdump to allow the use of NS prefix for record element.
524 Added new function yaz_log_xml_errors.
526 Allow (but warn) unknown XML attributes in MARCXML parsing.
528 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
530 The UTF-8 to MARC-8 conversion now uses a different set of characters
531 for Greek symbols. Bug #2120.
533 --- 3.0.26 2008/02/21
535 Added yaz_daemon (daemon.h).
537 Fixed bug #2068: pkg-config trouble
539 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
541 --- 3.0.24 2008/01/28
543 Document --with-xml2 option.
545 Added OPAC XML XSD (etc/opacxml.xsd).
547 Allow glob mask for name attribute in retrieval element for the
548 generic frontend server's retrieval facility.
550 Changed yaz_poll_poll to return yaz_poll_except for all returned events
551 except POLLIN/POLLOUT.
553 Fixed error handling in cs_listen. Bug #2037.
555 --- 3.0.22 2008/01/20
557 Fixed version in yaz/yaz-version.h.
559 Fixed bug #2027: Crash when closing connection.
561 Changed configure so that ICU support is only enabled if only ICU
562 and Libxml2 is available (because the ICU chain is XML based).
564 --- 3.0.20 2008/01/15
566 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
567 is built. Only this DLL depends on the ICU runtime.
569 yaz-ziffy is no longer part of YAZ. It is distributed separately by
570 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
572 Changed license of CCL module to 'Revised BSD'. After consultation with
573 remaining members of the original EUROPAGATE consortium, we are re-issuing
574 the CCL module without a separate license. The software was developed by
575 Index Data as part of a research project. The special license was included
576 to help feed usage information back to the project consortium to support
577 project evaluation. At this time, the project consortium has long-since
578 disbanded, and the majority of the original principals have retired. At the
579 same time, we have significantly modified the software during the following
580 years, to the point where very practically no original code remains. To
581 simplify re-use of the software, we have contacted those members of the
582 consortium who could be reached, and agreed to re-issue the module as a
583 proper part of the YAZ package.
585 Tcl scripts uses /usr/bin/tclsh as preferred shell.
587 CQL closer to being version 1.2 compliant. CQL also allows free-form
588 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
591 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
592 bug could make Extended services handling crash in the ZOOM layer. This
593 bug was only present in YAZ 3.0.18.
595 --- 3.0.18 2007/12/19
597 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
600 yaz-marcdump reads and writes collection wrapped records.
602 Handle OPAC for record conversion module.
604 Fixes for ICU wrapper.
606 Allow ICU libs to be controlled with --with-icu .
608 --- 3.0.16 2007/11/12
610 Added yaz_poll which is a wrapper for select/poll. When poll is available
611 and non-buggy, it is used, by yaz_poll . This allows more than 1024
612 sockets to be in use.
614 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
615 functionality through an XML based configuration (ICU chain). This system
616 is useful for search facilities such as Pazpar2 and Zebra that needs to
617 perform tokenization of indexed material. The ICU code in a separate
618 library libyaz3_icu.a.
620 Added HTTP tunnel facility for COMSTACK, bug #1752.
621 This is a facility that allows a Web proxy, such as squid, to tunnel
622 Z39.50 traffic. This facility is "transparent" to must applications
623 using YAZ. It's enabled by using pseudo transport connect: followed by
624 the proxy address, followed by command, then follwed by he regular
625 "virtual" addresss. For example,
626 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
628 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
630 --- 3.0.14 2007/09/21
632 Fixed bad memory reference in ZOOM_record - cuased by member not being
633 initialized. This was a problem only in YAZ 3.0.12.
635 Fixed bug in conversion from MARC to XML: Non-XML characters in control
636 fields were not removed.
638 Changed the way C code is generated from codetables.xml. Made a MARC-8
639 conversion trie for each characterSet section rather than codeTable.
640 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
641 of codetables.xml from Larry Dixson, LOC. Bug #1464.
643 --- 3.0.12 2007/09/12
645 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
646 from ZOOM_record_error).
648 ZOOM C function ZOOM_record_get returns record schema for type="schema".
650 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
652 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
654 Better SRW-to-Bib-1 diagnostic mapping.
656 ZOOM C and yaz-client announces SRU version 1.2 by default.
658 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
661 Fixed in yaz_sru_decode to allow other version than 1.1.
663 --- 3.0.10 2007/08/22
665 Added support for SRU scan for ZOOM.
667 Added support for the use of the older versions or Extended Service
668 Update in ZOOM. To faciliate this, an option "updateVersion" may be
669 set to the version , 1=first, 2=second, 3=third. The third version is
670 what ZOOM C has used so far. And that, obviously, is the default.
672 Added support for CCL queries in Z39.50 queries sent to the GFS (and
673 therefore in Zebra and in SimpleServer-based applications). The new
674 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
675 qualifier file used to transform incoming CCL queries into Type-1 RPN,
676 which is passed into the back-end search callback function.
678 Added support for HTTP Basic authentication in clients: the SRU/W
679 codec encodes the username/password elements of the PDU structure
680 appropriately, and these may be set using the "user" and "password"
681 options in ZOOM-C applications (the same options that are used for
682 Z39.50 authentication).
686 Fixed bug #1208: SSL appears to be broken in ZOOM.
688 Fixed bug #1206: Libxml2 include path weirdness.
690 Added oid_name_to_dotstring.
692 Allow elementSetName to be specified for ZOOM C record update.
694 Allow waitAction to be specified for ZOOM C based for Extended Services.
696 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
697 syntax OID. Bug introduced in YAZ 3 series.
699 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
703 Fixed bug #1157: yaz-client does not read .yazclientrc from current
704 directory. yaz-client now reads commands from file given by option -f
705 if specified; then tries to read .yazclientrc in current directory.
706 Failing that, it reads .yazclientrc from user's home directory.
708 Added support for correlationInfo Note and ID for Record Update via
711 Added yaz-client command querycharset which specifies character set for
712 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
713 (termListAndStartPoint).
715 Charset ISO5428:1984 is an alias for ISO5428-1984.
717 Implemented a way to perform scan in a result set using Z39.50. This
718 is achieved by attaching the result set name in the characterInfo
719 (type InternationalString) of OtherInformation in the Scan Request PDU.
720 The result set is identified in the otherinformation by the new OID:
721 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
722 This allows for scan in result set and faceted search . Zebra did some
723 of this in the APT term using attribute type 8 and value being result
724 set. Using the OtherInformation approach for this is cleaner and easier
725 to work with in proxies and the like. This facility can be used in
726 yaz-client using new command setscan which takes a result set as first
727 argument, start position (APT) as second.
729 Changed decoding of SRU XML packed records to deal with servers that
730 have recordData with XML data with multiple root nodes. Also make
731 comparison for recordPacking case insensitive. Again, one server
732 returns "XML" where others return "xml".
734 For SRU responses allow Content-Type application/xml as well as text/xml.
738 Fixed bug in character set conversion of BER strings. Bug introduced
743 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
745 For OID class, use oid_class consistently.
747 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
750 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
751 character set for bibliographic information interchange". By Giannis Kosmas.
753 Added documentation on new OID API.
757 Changes to generic frontend server interface: added new member
758 'query_charset' for bend_initrequest structure. A backend init handler
759 should set this member to its native character set for query terms.
760 When defined, the frontend server logic will announce this character set
761 to a client if the negotiationModel bit is set by the client. All server
762 implementors are encouraged to specify this. If a backend server does not
763 specify this a warning is issued using yaz_log(YLOG_WARN,..).
765 Added CCL utility to remove terms (stop words) from resulting RPN
766 tree. This is handled by functions with prefix ccl_stop_words_ .
768 New ZOOM C option, "rpnCharset", which allows client-side conversion of
769 terms in RPN queries.
771 Clean-up the CCL API. Moved some internal structures from ccl.h to
772 private header cclp.h. Changed ccl_parser_create so that a Bibset must
773 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
774 This is replaced by ccl_parser_find_str which takes a string instead.
776 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
777 libyaz.la is the core of YAZ except the generic frontend server and
778 does not depend on POSIX threads anymore. libyaz_server.la is the
779 generic frontend server facilities and uses POSIX thread functionality
780 if available. The libyaz.la no longer depends on POSIX threads because
781 the number of global structures is limited. NMEM no longer re-uses blocks
782 between threads ; it simply free's memory immediately but allocates in
783 "large" chunks as usual. We don't expect any performance penalties
784 because of this. The yaz_log system is still using a global log_level so
785 caution must be taken when modifying it with yaz_log_init_.. +
786 yaz_log_mask_str. This, however, should not cause any trouble because
787 these functions are called during initialization of application code
788 anyway. `yaz-config --libs server` returns libs for server applications;
789 `yaz-config --libs` returns libs for non-server applications.
791 New OID database - with public definitions in oid_db.h. Removed old OID
792 database including the head oid.h and definitions such as enum oid_value
793 and struct oident. The new OID database uses the same string names as
794 before but the 'protocol' is gone. There are now only two representations
795 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
796 converts from string to OID; functions with prefix yaz_oid_to_string
797 converts the other way.
799 Change to emit_term() in CQL-to-PQF query translation: when a term has
800 the /regexp relation modifier, do not process it for leading and
801 trailing "^" and "*", which have quite different meanings in regular
804 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
805 write handlers no longer carries a 'last' parameter. This will make
806 yaz_iconv flush "less" characters. A flush is performed by call to
807 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
809 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
810 removed, because function yaz_query_to_wrbuf does the same.
812 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
813 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
815 Deprecated MARC utility functions removed.
817 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
820 Branch split: YAZ_2_1_55_branch
822 --- 2.1.54 2007/03/16
824 Fix to ZOOM-C so that transparent reconnection is properly handled on
825 connections that are in asynchronous mode.
827 Fixed compilation on OpenBSD 4.0.
829 Large strings in GRS-1 records are now properly displayed in yaz-client.
831 Added character conversion support for "advancegreek"; based on patch from
834 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
835 sequence is met. Before the error was not set so it would be unknown.
837 Adjust yaz-marcdump MARC reader so that it skips until record separator
840 --- 2.1.52 2007/03/07
842 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
843 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
844 fd_set structure used as a bitmask for the FDs to be selected on.
846 Using ACX_PTHREAD macro to check for POSIX threads.
848 Fixed have-vsnprintf check.
850 --- 2.1.50 2007/02/23
852 Fixes for configure on BSD. Bug #900.
854 Added snprintf/vsnprintf wrappers for systems that don't have
855 limits (heavens forbid).
857 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
858 created before all previous tasks were completed and removed from the
859 task queue, the new task could be removed by a mistake.
861 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
863 Implemented pass-through CQL-to-PQF conversions. Bug #861.
865 Fixed bug #832: Problem with MARC/charset in yaz-client.
867 Fixed bug #668: save command line history for yaz-client.
869 Fixed bug #830: pkg-config support.
871 --- 2.1.48 2007/01/23
873 Extended ZOOM result set options with two options that may be read by
874 a client: resultSetStatus and presentStatus with values as specified for
876 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
878 Fixed bug #827: Using SSL fails on Debian etch.
880 Fixed bug #826: Weird looking chars for set of MARC records.
882 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
883 that is treated as an ItemOrder with itemRequest being an XML document
884 external. The value of "doc" is the content.
886 Extended the GFS search facility. New member of bend_search_rr
887 'estimated_hit_count' signals that hits is known to be an estmate
888 (higher or lower than real hit count). New member 'partial_resultset'
889 signals that the search was partial (hit count is lower or equal than
890 real hit count). For Z39.50, the information is stored in resultSetStatus
891 member of SearchResponse APDU. For SRU, the information is signalled
892 via SRU diagnostic 59: "Result set created with valid partial results
895 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
897 --- 2.1.46 2007/01/13
899 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
901 Added ZOOM_connection_peek_event.
903 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
904 the following new functions:
905 ZOOM_event_nonblock, ZOOM_connection_process,
906 ZOOM_connection_get_{socket,mask,timeout},
907 ZOOM_connection_fire_event_{timeout,socket}.
908 The existing blocking event handler, ZOOM_event, is a wrapper for the
909 + blocking ZOOM_event_sys_{poll,select}.
911 Implemented function ccl_xml_config which parses XML version of CCL
912 configuration (bug #798).
914 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
916 Added timings utility (yaz/timing.h)
918 --- 2.1.44 2007/01/03
920 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
923 Fixed bug #779: Rotation of apdu.log fails.
925 Fixed for character set conversions:
926 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
927 Honor G1 set in MARC-8 decoding.
929 --- 2.1.42 2006/12/17
931 Fixed bug #775: char conversion does not handle Alternative UTF-8
934 Implemented function yaz_marc_read_line which parses MARC line format
935 records. There is a wealth of formats out there. So far, this function
936 reads line records produced by yaz_marc_write_line.
938 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
939 more generic and easier to remember(!) options: -i format and -o format
940 which specifies input format and output format respectively - where
941 format is one of "marc", "marcxml", "line", "marcxchange".
943 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
944 does not print anything except warnings for records.
946 For yaz-marcdump, added support for MARC split into files (-s) with a given
949 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
950 spec, at http://www.loc.gov/standards/sru/record-update/
951 This has changed the binary layout of the following structs:
952 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
953 bend_update_rr . Patch by Ko van der Sloot.
955 Added GFS utility function bend_assoc_is_alive which returns 1 if
956 association is still alive (client is connected); 0 otherwise (client
957 closed connection). This allows busy servers to stop working for
960 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
961 been a separate piece of software. This version of ziffy has been modified
962 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
964 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
966 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
967 Client code may now interrogate options such as "init_opt_sort" to
968 find out whether the server claims to support various options.
970 --- 2.1.40 2006/11/27
972 Added utilities yaz_{set,get}_esn to set/get element set name from
975 Removed the build of libyazthread.la. The libyaz.so is the threaded version
976 of YAZ and has been so since YAZ 2.1.10.
978 Implemented ZOOM_record_error which returns error information for
979 record (surrogate diagnostic).
981 --- 2.1.38 2006/10/31
983 Updates for SRU Update by Ko van der Sloot:
984 1. Changed name from "operation" to "action"
985 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
986 versions in the code, marked as 'backward compatible'.
987 3. Added diagnostics for SRU Update.
989 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
991 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
993 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
995 For GFS, fixed problem with SRU diagnostic 'First record position out of
996 range' being issued for 0 hits.
998 zoomtst10 part of Windows Build.
1000 --- 2.1.36 2006/10/13
1002 Implemented yaz_filepath_comp which splits a path into file path
1003 components (required by Zebra 2.0.3+).
1005 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1006 BSD inspired license until now so this should not have any real impact on
1007 anybody. See http://www.opensource.org/licenses/bsd-license.php
1009 Fixed bug #687: Missing log lines.
1011 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1014 Fixed bug #689: SRU diagnostics to be added.
1016 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1017 whether a connection is idle (no more work do do).
1019 --- 2.1.34 2006/10/04
1021 Change type of optval from long to int for invocation of setsockopt with
1022 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1024 Added support for specifying the max log file size for the Generic
1025 Frontend Server. The size is given with option -r.
1027 --- 2.1.32 2006/09/21
1029 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1031 --- 2.1.30 2006/09/17
1033 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1036 Fixed bug in Generic Frontend Server that could cause a server to stop
1037 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1039 For the generic frontend server, the maximum record size is used as maximum
1040 size of incoming packages (SRU + Z39.50). The value until was previously
1041 only used in Z39.50 Init negotiation and, later, in a session controlled
1042 sizes of records returned. This is controlled using -k option. It can be
1043 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1045 --- 2.1.28 2006/09/04
1047 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1050 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1052 New option for yaz-marcdump -lpos=value which allows setting a portion
1053 of MARC header to a certain value.
1055 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1057 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1058 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1060 --- 2.1.26 2006/08/15
1062 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1065 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1067 --- 2.1.24 2006/08/08
1069 Fixed MARC ISO2709 encoding routines to deal with character set
1072 Minor changes to GFS logging. Database included in search request log
1075 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1076 cached/multiple records.
1078 Shared libraries are built by default on Unix+configure.
1080 Changed cql2pqf transformation to use a different evaluation order. The
1081 new order is: always, relation, structure, position, truncation, index
1082 and relationModifier. Old order was: always, relation, relationModifier,
1083 structure, index, position, truncation. Note that the the latter ones
1084 override former ones for identical attributes.. The new scheme means that
1085 it is possible to override any existing attribute with a relationModifier.
1086 And also that it is possible to override everything for the index rule
1087 (except the ones listed in relationModifier). No order is perfect but this
1088 one, we believe, covers more real cases.. The "always" should have been
1089 called "default", since the attributes there can be overridden with all
1092 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1093 compilation phase, but also for yaz-config --cflags output. This allows
1094 us to have public headers with Libxml2 stuff in them . It should also,
1095 eventually, make Libxml2 checks redundant in packages using YAZ, such
1098 --- 2.1.22 2006/06/15
1100 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1101 stored in uri, message and details.. Previously diagnostics were stored
1102 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1103 compatibility.. but he's probably the only one affected, so.
1105 Added support for CCL, compiled on the client side, in ZOOM-C. This
1106 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1107 input; the resulting query objects can be used for for searching with
1108 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1110 YAZ' configure searches for OpenSSL by default.
1112 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1113 SL_CTX_use_certificate_file. See
1114 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1115 for more info. Thanks to Ko van der Sloot.
1117 --- 2.1.20 2006/06/02
1119 Bug #600: SRU GET, POST support for yaz-client. Introduced
1120 command 'sru' which selects method SOAP/GET/POST.
1122 Allow missingValueAction to be specified for the sortspec string -
1123 function yaz_sort_spec. By default, the missing value action is null.
1124 Use ! to specify "abort". Use = followed by stringvalue to specify default
1127 Ensured that Present-handler (if defined) is called in GFS before any call to
1128 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1129 searchRetrieve requests.
1131 Documentation for YAZ is now based on the Docbook XML/XSLT using
1132 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1133 is no longer depending on jade/openjade or docbook-to-man scripts.
1134 PDF is no longer part of the distribution - but can optionally be
1135 made using DSSSL/jadetex or FOP.
1137 Added retrieval handling support in Generic Frontend Server to support
1138 conversion between MARC/XML as well as XSLTtransforms. See
1139 etc/yazgfs.xml for an example.
1141 Added Authentication support to Generic Frontend Server in SRU
1142 mode. Authentication using HTTP Basic is supported, as is the use
1143 of 'x-username' and 'x-password' parameters in the request itself.
1145 Added support for a new character set MARC8s identical to MARC8 except
1146 that it converts combined characters to single Unicode characters in the
1147 Latin-1 range (when possible).
1149 --- 2.1.18 2006/04/24
1151 ASN.1 compiler 0.4: generates brief Doxygen file header for
1152 generated .h/.c files.
1154 Utility yaz_iconv now supports conversion to MARC-8.
1156 New facilities for the MARC module. The reading - and writing of
1157 content are separate methods for the yaz_marc_t handle. The following
1158 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1159 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1160 format). Write functions have prefix yaz_marc_write_.. The existing
1161 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1162 available. Removed support for OAI-MARC and simplexml (not the
1163 simplexml from PHP5).
1165 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1166 to be returned for this connection.
1168 --- 2.1.16 2006/03/31
1170 Allow multiple languages and charsets to be specified with
1171 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1172 negcharset iso-8859-1,utf-8
1174 Translation of proximity nodes from CQL into PQF now works.
1176 Moved to automake 1.8, 1.9.
1178 Added function yaz_log_set_handler which allows a log handler to be
1179 installed. This handler will be called for all log messages. Output
1180 to file is also produced; but that can be disabled by passing NULL
1181 fname to yaz_log_init_file.
1183 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1185 For SRW (including GFS), accept application/soap+xml as content-type
1188 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1189 produces NO stylesheet reference even if a default stylesheet is specified
1192 --- 2.1.14 2006/03/14
1194 Updated Windows package to include yazd.dll + yazd.lib for the
1195 Development component.
1197 If the environment variable YAZ_LOG is set, then it is used as a
1198 string indicating the default level of logging to use if not
1199 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1200 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1201 used as before. So, for example, to omit warnings from YAZ logging,
1202 export YAZ_LOG=-warn
1204 cql_transform() now map structure and other attributes before indexes,
1205 so that index-specific structures and other attributes can override
1206 defaults. So now a combination of mapping specifications such as:
1208 index.dc.date = 1=date-modified 4=5
1209 does the right thing.
1211 cql_transform() now also respects the "always" mapping specification,
1212 which establishes an initial set of attributes to be used for all
1213 terms except where overridden by more specific attributes associated
1214 with the index, relation or modifier.
1216 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1217 which mode to use; one of "post", "get" or "soap" (SRW, default).
1219 Fixes for yaz_iconv routines: changed trie-based character set conversions
1220 to use only non-negative values for bit fields due to Sun's C compiler not
1221 supporting negative values.
1223 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1224 sequences where not read correctly. Fix by Rustam Usmanov.
1226 Updated win/makefile to use options, settings which makes things
1227 compile with VS C 2005.
1229 --- 2.1.12 2006/02/01
1231 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1233 In ZOOM socket code, use select instead of poll on MacOSX.
1235 ZOOM-C now support client-side compilation of CQL into RPN that is
1236 sent to the server, enabling CQL to be used against all Z39.50
1237 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1238 ZOOM_query object, and submit it using ZOOM_connection_search().
1239 The CQL-to-RPN translation uses a configuration file, the name of
1240 which must be specified in the Connection's "cqlfile" option.
1242 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1243 function, which takes as its start-term parameter a ZOOM_query object
1244 (which may have had either CQL or RPN set into it).
1247 --- 2.1.10 2005/11/29
1249 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1250 GFS to support this as well. Backend handler, bend_srw_update, does the
1251 update work. Code contributed by Ko van der Sloot.
1253 Allow retrieval of Search Result-1 information in ZOOM by the use of
1254 options that are attached to a result set. ZOOM documentation updated
1257 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1258 UTF-8 conversion. Patch by Raj Patel.
1260 Added option -m to GFS to control formatting of timestamps in log file.
1262 Added 'exit' as synonym for 'quit' in yaz-client
1264 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1265 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1266 for the new members. Patch by Ko van der Sloot.
1268 Added support for SRU POST. It is supported for content-type
1269 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1271 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1272 Instead make the library libyaz.la multi-threaded. Threading as a whole
1273 can still be disabled by configure option --disable-threads. Previosly,
1274 with older GLIBCs there were problems with MT libs under Apache. This
1275 has now been fixed a long time ago.
1277 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1280 CQL module modified to be case insensitive for relations/indexes/operations.
1282 Fixed bug in CQL transform code: incorrect value relationModifieder
1285 Added 'show all' command for yaz-client which retrieves all results
1288 Added new yaz-client, xmles, which takes a (private) OID and
1289 a document to be sent as an extended service request.
1291 Describe new yaz-client commands wait_response and set_auto_wait.
1293 Increase TCP/IP listener backlog from 3 (which I am guessing was
1294 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1295 that the socket will queue as many incoming connections as it's able
1296 to handle ongoing connections. In other words, it will never now
1297 refuse a connection that it would be able to handle merely because
1298 it's not got around to accepting() enough of the pending connections
1299 yet. This is the behaviour anyway under Linux, where the listen()
1300 argument is ignored; but not under BSD and on systems such as
1301 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1302 YAZ-based servers should now be uniform across operating systems in
1305 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1306 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1307 This allows yaz-marcdump to read large MARC batches (>2 GB).
1309 Modified all YAZ source files - except the source which is auto-generated
1310 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1313 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1314 corresponding to the existing *_setl() function. These allow option
1315 values containing arbitrary valuues.
1317 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1318 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1319 except that it returns an indicator of whether or not the sort
1320 criterion was accepted (0 for OK, -1 for invalid).
1322 --- 2.1.8 2005/06/07
1324 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1325 MARC output rather than returning "new" buffer.
1327 yaz-client warns about unknown init options.
1329 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1331 --- 2.1.6 2005/05/24
1333 Added support for SRW sort in Generic Frontend Server. Patch
1334 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1335 sortKeys - or NULL if none is provided.
1337 Fixed bug #307: It was impossible to specify indefinite/no timeout
1338 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1341 Added support for multiple languages and charsets to be specified in
1342 ZOOM. Each charset/language is separated by a blank. If negotiation is
1343 in effect in init-response, Option
1344 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1345 Code based on patch by Vasiliy Osadchuk.
1347 Fixed bug #306: infinite recursion that occurred when calling
1348 yaz_log_level_init as the first call (before other log level or
1351 Fixed bug in scan handling in front end server: if preferred-Position-In-
1352 Response was non-present, a NULL pointer referece was performed.
1354 --- 2.1.4 2005/04/26
1356 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1357 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1358 now defined for all those error codes. So instead of putting 109 in
1359 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1360 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1362 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1365 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1367 Program yaz-client now exits and produces an error message if multiple
1368 Z39.50 servers are specified on the command line (none or one allowed
1371 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1374 --- 2.1.2 2005/03/16
1376 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1378 Fixed bug #272: Preserve spacing for CCL terms.
1380 --- 2.1.0 2005/03/14
1382 Added support for virtual hosts and multiple backend servers for
1383 the YAZ frontend server. The configution is XML based and
1384 support specificition of CQL to RPN mappings and explain information.
1385 See section "Virtual Hosts" in the YAZ manual.
1387 Extended OPAC display utility. OPAC display utility renders
1388 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1389 to supplement yaz_marc_decode_wrbuf.
1391 Fixed a bug in MARC decoder that could caused it to crash for some
1392 invalid MARC records. More diagnostics and warnings where added in
1393 XML output (warnings, etc are stored in comments).
1395 --- 2.0.34 2005/02/08
1397 Fixes for UNIX domain sockets. Bug #261.
1399 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1401 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1402 Added yaz_marc_subfield_str which defines subfield lead string which is
1403 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1404 yaz_marc_endline_str which defines end of fields string used in
1405 YAZ_MARC_LINE format. Default string is newline.
1407 Experimental support for MarcXChange. This format can be produced
1408 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1409 http://www.bs.dk/standards/MarcXchange.xsd
1411 Added yaz-client commands scansize that sets maximum number of
1412 entries to be returned by scan.
1414 --- 2.0.32 2005/01/11
1416 Added support for SRW scan in yaz-client and Generic Frontend Server.
1418 * Added whereInList member to SRW Scan Term.
1420 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1422 Fixed NMEM system to return aligned blocks on the smallest boundaries
1423 that are suitably aligned for all possible types on the particular
1424 architecture YAZ is being built for.
1426 --- 2.0.30 2005/01/04
1428 Fixed numerious warnings that was issued with newer versions of GCC.
1430 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1431 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1434 Make YAZ Generic Frontend Server slightly faster.
1436 Enhance (and reduce) logging for Generic Frontend Server.
1438 Revert YAZ log system so that it flushes every write operation
1439 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1441 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1442 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1443 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1444 will effectively disable old definitions.
1446 --- 2.0.28 2004/11/09
1448 Added yaz_log_time_format which specifies log format using
1451 Added yaz_log_module_level which returns mask for a module. Value
1452 is non-zero mask a if module is enabled; zero if disabled.
1454 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1455 in include/yaz/cql.h.
1457 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1459 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1461 Fixed bug #172: RPM builds does not enable SSL.
1463 Doxyfile.in part of dist. Doxyfile generated by configure.
1465 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1466 are given and the corresponding component does not exist.
1468 Extend CCL documentation in YAZ reference. Describe r=r.
1470 --- 2.0.26 2004/10/01
1472 Fixed MARC->MARCXML conversion to properly deal with
1473 fields, subfields, indicators having non-ASCII characters.
1475 Fixed MARC->MARCXML conversion so that ASCII control characters
1476 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1479 Added YAZ GFS support for conversion from Z39.50 surrogate
1480 diagnostics to SRW surrogate diagnostics.
1482 Bug fix: YAZ GFS did not return schema in explainResponse.
1484 --- 2.0.25 2004/09/30
1486 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1487 now converts recordSchema to elementSetName as well as schema URI.
1489 Fixed bug in COMSTACK that prevented HTTP request packages from being
1492 --- 2.0.24 2004/09/29
1494 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1495 does not require white-space before and after the dash in a range, e.g.
1496 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1499 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1500 due to new GCC removing "redundant" code.
1502 Added yaz-client commands scanpos and scanstep that sets preferred
1503 position and step-size for scan.
1505 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1507 Added CCL utility ccl_qual_buf which parses one or more CCL
1508 spec lines in a buffer.
1510 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1511 of name and value - ignoring empty lines and comments.
1513 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1515 Added odr_get_element_path which returns current element path for an
1516 ODR handle. This utility is useful in error handling or user-defined
1519 Added ODR_PRINT utility odr_set_stream which is is a more generic
1520 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1521 to a write function and pointer to close function. The close function - if
1522 non-NULL - will be called during odr_destroy.
1524 Fixed bug in CCL parser where truncation char was not removed from
1525 right side when truncation=both was in effect.
1527 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1530 --- 2.0.23 2004/08/11
1532 Fix buffer overrun in CQL parser when dealing with proximity (%).
1534 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1535 to UTF-8/UCS conversion is now only based on codetables.xml.
1537 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1539 --- 2.0.22 2004/08/06
1541 Add support for more "commit changes" in ZOOM (uses Extended Services).
1543 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1546 Yet another small fix for configure of SSL.
1548 --- 2.0.21 2004/05/14
1550 Fix SSL libs for configure when --with-openssl=DIR is given.
1552 --- 2.0.20 2004/05/10
1554 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1556 SSL comstack now uses yaz.pem certificate file on server side
1557 by default. Certificate filename can be configured by calling
1558 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1560 Fix bug regarding multiple calls to ZOOM_connection_connect.
1562 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1564 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1565 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1567 ZOOM now allows inspection of X509 peer certificate for verification.
1568 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1570 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1571 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1572 as "modular" but it simplifies things.
1574 Added cs_get_peer_certificate to that returns peer X509 PEM.
1576 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1577 NULL if SSL is unavailable.
1579 Documentation about MARC decoding tools.
1581 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1583 --- 2.0.19 2004/03/30
1585 Rename CHANGELOG to NEWS to follow GNU style packing.
1587 Fix bug with missing initialization of member in init_diagnostics.
1588 This bug affects threaded version of GFS server.
1590 --- 2.0.18 2004/03/20
1592 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1595 Ensure zlib.dll is packed with Windows install.
1597 --- 2.0.17 2004/03/17
1599 Fix encoding of xsd:string to use text instead of CDATA.
1601 Fix endless loop in CQL parser with unbalanced ".
1603 Use a more compact way to store MARC-8 conversion tables.
1605 --- 2.0.16 2004/03/16 Debian only
1607 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1610 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1615 --- 2.0.15 2004/03/01
1617 Another fix for decoding of XML packed records.
1619 --- 2.0.14 2004/02/25
1621 Fixes for Chunked encoding. White space not ignored after length spec.
1623 Update NS and use default NS for SRW diagnostic elements.
1625 --- 2.0.13 2004/02/23
1627 Implement ZOOM_resultset_cache_reset which resets record cache.
1629 Implement ZOOM_resultset_sort which sorts a result set.
1631 Implement chunked HTTP transfer.
1633 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1635 --- 2.0.12 2004/02/16
1637 Added member 'schema' to bend_explain_rr structure so that backend
1638 can specify explain record identifier. Defaults to Zeerex 2.0.
1640 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1642 --- 2.0.11 2004/02/16
1644 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1647 Added init command for yaz-client which sends "extra" init request.
1649 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1650 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1652 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1654 Make ZOOM error code for "invalid query".
1656 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1658 --- 2.0.10 2004/02/05
1660 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1663 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1665 Added option -p <file> to make Generic Frontend Server to write PID file.
1667 Added option -D to put Generic Frontend Server in background on its own.
1669 Make ZOOM C recognize option "password". If unset, "pass" is used
1670 (for backwards compatibility).
1672 Fixed a bug in Generic Frontend Server that could make it crash if a
1673 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1676 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1677 Must be issued before open, in order to be in effect.
1679 --- 2.0.9-6 2004/01/12 Debian/Windows
1681 Make the SRU server more picky WRT unknown params, etc.
1683 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1685 New YAZ client command, options, that sets Z39.50 options.
1687 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1688 options from a string of tokens (one token for each option bit).
1690 Update SRW diagnostic code messages.
1692 --- 2.0.9-5 2004/01/07 Debian/Windows
1694 Handle user defined stylesheet for SRW/SRU.
1696 --- 2.0.9-4 2004/01/06 Debian/Windows
1698 Fix bug in decoding of Content-Length.
1700 --- 2.0.9-3 2004/01/06 Debian/Windows
1702 Fix a bug with decoding of XML packed records.
1704 --- 2.0.9-2 2004/01/05 Debian only
1706 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1708 Fix bug in SRW/SRU diagnostics decoding.
1710 --- 2.0.9 2004/01/05
1712 Fixed bug in Generic Frontend Server which could drop records exceeding
1713 preferred message size. Reported and fixed by Irina Dijour.
1715 Fixed calculation of package size for structured records in Generic
1716 Frontend Server. Reported and fixed by Irina Dijour.
1718 Fixed namespace for SRW/SRU diagnostics.
1720 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1722 --- 2.0.8 2003/12/22
1724 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1725 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1728 CQL changes to reflect recent changes to the specification:
1729 * Documentation talks about context sets instead of index sets.
1730 * Documentation talks about indexes instead of qualifiers.
1731 * The CQL-to-PQF transformer's configuration file now uses
1732 "index.set.name = <attributes>" instead of the old form
1733 "qualifier.set.name = <attributes>". (Both forms are still
1734 understood but the latter is deprecated.)
1735 * CQL terms with no explicit index specified are now interpreted as
1736 cql.serverChoice instead of srw.serverChoice (which of course
1737 behaves exactly the same.)
1739 --- 2.0.7 2003/12/16
1741 MARC conversion can now generate ISO2709 output in another
1742 character set. yaz-marcdump uses this facility if you invoke it
1745 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1746 functions from there can be used from C++.
1748 --- 2.0.6 2003/12/04
1750 Frontend server now transfers memory from decoded packages to stream
1753 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1754 references to show up.
1756 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1757 the ZOOM Abstract API. The older names for the same options are still
1758 also supported for the benefit of old applications.
1760 ZOOM-C supports "implementationId" and "implementationVersion" options
1761 to go along with "implementationName". These allow the user code to
1762 specify identification strings to be sent to servers.
1763 Add OID for the new ExtLite attribute set.
1765 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1766 as requested/supplid by Ere Maijala <ere@atp.fi>
1768 For generic frontend server, reverse the order of
1769 "toolkit-supplied / application-supplied" strings sent as implementationId,
1770 Name and Version. Also, remove the spaces around the slash. This brings
1771 the GFS in line with the behaviour of ZOOM-C on the client side.
1773 Add function ZOOM_scanset_display_term.
1775 yaz-client shows scan displayTerm if present.
1777 Utility yaz-iconv is now installed by default along with the man page
1780 Extend configure check for OpenSSL to use pkg-config where available (such
1783 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1784 server to specify uid/gid/mask for socket using the format
1785 unix:[user=uid,][group=gid,][umask=mask,]file=path
1786 If file= is omitted the existing format is assumed, e.g.
1788 in which case the mask is 0666 (rw for everybody).
1790 Major restructure of YAZ source. All source in libyaz is in src directory.
1791 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1792 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1794 Added man page for utility yaz-marcdump (used to be called marcdump).
1795 yaz-marcdump is installed by 'make install'.
1797 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1798 of incoming package failed.
1800 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1802 Change prototype of odr_perror: add const to message string.
1804 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1806 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1807 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1808 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1809 DNS lookup. There should not be any compatibility problems with this
1810 assuming that blocking=1 or 0 is used.
1812 Fix bad reference in UNIX comstack in function cs_addrstr.
1814 Fix for compilation on AIX.
1816 The generic front-end server (server/seshigh.c) now supports returning
1817 Init diagnostics to the client in User-information-field, in
1818 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1821 --- 2.0.4 2003/09/04
1823 Allow any CQL relation (not just all,any,exact,scr).
1825 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1826 that features the same UI.
1828 Implemented command update0 in YAZ client which is equivalent to
1829 update but uses old of Ext Update ASN.1.
1831 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1832 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1833 Previously no OID was used for this info.
1835 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1836 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1837 returns 'malformed search term' otherwise.
1839 SortResponse member resultCount now set to NULL in sort handler of
1842 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1845 Add three new utility functions for translating OIDs between various
1846 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1847 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1848 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1849 char *oid_to_dotstring(const int *oid, char *oidbuf);
1850 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1852 Reverted modifications for ES Update definition for z_IU0Update
1853 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1854 is back to YAZ 2.0.2.
1856 String value attributes for CCL parser.
1858 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1859 which their FirstSearch server returns in Init responses, sometimes
1860 carrying useful diagnostic information when Init fails. This has the
1861 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1862 "z39.50/oclcui.asn", where its definition is somewhat different from
1863 what OCLC document on their web-site, as required to interoperate with
1866 Support for anonymous authentication in yaz-client. Use the command
1869 * Fix the OID of the Index Data-local "admin" Extended Service from
1870 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1871 the 1000, which indicates a locally-defined OID, was a mistake.
1873 --- 2.0.3 2003/06/20
1875 Fix CCL directive @case handling so that it affects string match for
1876 both CCL keywords and qualifiers.
1878 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1879 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1880 Decoder has been updated with ASN.1 changes as listed in
1881 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1882 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1883 z_IUUpdate, remains unchanged.
1885 ZOOM_record_get may now return a record in a specific character set.
1886 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1887 "from" is the character set of record as returned by target. "to" is
1888 the character set to be returned. If omitted, "to" is UTF-8.
1890 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1892 New ODR utility, odr_getelement, which returns name of element for
1893 which encoding/decoding failed.
1895 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1896 in cases where a required element was omitted.
1898 Bug fix: some MARC8 sequences were not converted.
1900 New ZOOM option "step" which specifies number of records to be
1901 retrieved in one chunk. Used in conjunction with "start" and "count".
1903 SRW support for yaz-client. Use scheme http: to use it, e.g.
1906 yaz-client no longer does (un)intelligent character set conversions
1907 by default. Can be enabled with charset and marc_charset commands.
1909 xmalloc trace fix for 64-bit systems such as DEC alpha.
1911 Solaris 2.6 compile fix.
1913 New function, cql_strerror() translates SRW error codes, as returned
1914 by cql_transform_error(), into human-readable English strings. Used
1915 in yaz-client diagnostics when appropriate.
1917 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1918 converts it into a type-1 query which is sent to the server. This
1919 makes CQL available for use with all Z-servers, as opposed to the tiny
1920 minority that can handle CQL queries themselves.
1922 --- 2.0.2 2003/04/28
1924 New Debian package layout similar to the Redhat Package layout.
1926 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1927 and search result respectively.
1929 --- 2.0.1 2003/04/25
1931 Redhat package is now several packages: libyaz (runtime libraries),
1932 libyaz-devel (development and documentation, and yaz (utility programs).
1933 Package spec file by Morten Bogeskov.
1935 New member 'schema' in struct bend_fetch_rr which the name of requested
1936 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1937 handler MAY set this to reflect the schema of the returned record.
1939 New member 'display_term' in struct scan_entry. GFS now sets member entries
1940 and allocates scan entries to be filled by user scan handler. In previous
1941 version, entries member was allocated by the scan handler. That still works,
1942 but the GFS will ignore member display_term - assuming it was NOT set by
1943 the handler. The fact that the GFS now allocates the entries both allows
1944 for new members and makes a scan handler easier to write.
1946 Fix CQL lex buffer overflow.
1948 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1949 SRU default recordPacking is string.
1951 SRU protocol support for frontend server.
1953 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1955 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1957 Added scan for the ZOOM shell (zoomsh).
1961 * String Identifers for Schemas (Amendment 5).
1962 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1963 Old definition for schema
1964 Odr_oid *schema; /* OPT */
1969 Z_InternationalString *uri;
1970 #define Z_Schema_oid 1
1971 #define Z_Schema_uri 2
1974 * resultCount parameter to Sort Response (Amendment 1).
1975 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1977 Support for SRW 1.0 over HTTP. This is an optional feature and
1978 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1981 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1982 on the same port. SRW SearchRetrieveRequests are mapped
1983 to bend_init,bend_search,bend_fetch,bend_close.
1985 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1987 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1988 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1990 ZOOM connections are SRW based if schem http is used for hostname
1991 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1992 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1994 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1995 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1996 distance=n, order=true/false, relation=le, prox unit=word. If
1997 n is omitted, distance 1 is used.
1999 Fixed problem with C compiler include path in wrong order.
2001 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2002 on Solaris. Patch from Ko van der Sloot.
2004 New MARC decode API. All new functions operate on a yaz_marc_t
2005 handle. The most important new functions are: yaz_marc_create,
2006 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2007 decode and destroy respectively. Decoder can produce formats
2008 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2009 include/yaz/marcdisp.h.
2011 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2012 to UTF-8, UCS-32, wchar_t or Latin-1.
2014 * Prototypes for yaz_iconv_-functions moved to separate header
2015 include/yaz/yaz-iconv.h.
2017 Make a few private functions 'static' in unix.c. This prevents
2018 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2020 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2021 are set when Init Response is received.
2023 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2024 but returns diagnostic set as well.
2026 New function yaz_strerror which is a portable wrapper for
2027 strerror/strerror_r/GetLastMessage.
2029 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2030 is returned for MARC. If type is "oai", then OAI MARC is returned.
2032 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2035 --- 1.9.2 2002/11/26
2037 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2039 Fix bad race conditions on SIGTERM and terminate gracefully in
2042 Move retrieval (data1) module to Zebra since nobody seems to be
2045 Add GRS-1 render for ZOOM using same format as yaz-client.
2047 --- 1.9.1 2002/10/05
2049 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2051 Fix broken ESpec handling in data1 module.
2053 SGML reader parses comments and makes them part of the data1 tree.
2055 Added several type casts so that YAZ compiles as C++ code.
2057 ZOOM didn't handle PDU encoding failures properly.
2059 Added more Bib-1 diagnostics (approved extensions).
2061 GNU configure: better check for iconv.
2063 More portable use of accept, getpeername. Check for socklen_t. Use
2064 int/size_t if socklen_t is not defined.
2068 PQF parser rejects bad queries - including those with extra
2069 characters in them. PQF parser used to silently ignore that.
2070 Cleaner API for PQF added, which allows you to get detailed
2071 error information for bad queries (see yaz/pquery.h).
2073 Fixed bug in ZOOM_record_get for type "database".
2075 Implemented mini iconv library supporting conversions between
2076 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2078 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2080 --- 1.8.9 2002/08/20
2082 Fixed ZOOM C record cache so that preferredRecordSyntax and
2083 elementSetName is used to check for already fetched records.
2085 --- 1.8.8 2002/08/02
2087 Added three members in bend_initrequest structure to facilitate
2088 character set negotiation.
2090 Fixed a bug in frontend server that could cause indefinite
2091 loops under rare conditions.
2093 Revised character set utilities (charneg.h) so that encoding
2094 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2096 For PQF, directive @term <type> sets term type for Scan/Search.
2097 Here <type> is general, string, numeric, null. The term type
2098 is inherited - just like @attr.
2100 New call odr_set_charset that sets character set conversion for
2101 international-strings on a ODR stream. Prototype is:
2102 int odr_set_charset(ODR o, const char *to, const char *from);
2103 The InternationalString is still represented as C string in YAZ
2104 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2105 won't). On the protocol level, you can use any encoding.
2107 Support for UNIX sockets in ZOOM.
2109 Solaris recv sometimes returns errno == ENOENT. It is treated as
2110 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2112 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2113 both client and server. Code by Morten Bogeskov.
2115 --- 1.8.7 2002/05/22
2117 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2118 that they can be used directly from Visual Basic. You must recompile
2119 your windows APP if you're using ZOOM.
2121 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2122 Commands "lang" and "charset" sets language and character set respectively.
2123 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2124 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2126 Attributes from multiple CCL fields may be OR'ed rather than merged
2127 using directive "@field or". Fields are still merged by default -
2128 equivalent to "@field merge".
2130 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2133 Fixed bug in zget for parameter ExtendedServicesResponse.
2137 --- 1.8.6 2002/03/25
2139 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2141 Client displays USR.1:SearchResult-1 (hits per term).
2143 Additional Search Info for search in Generic Frontend Server.
2145 Fixed CCL parsing of "field=s".
2147 WIN32 installer - using the excellent NSIS software from nullsoft.
2149 Fixed CCL parsing of "field = - <number>".
2151 Added function yaz_marc_decode that decodes MARC for line mode
2152 display or XML (similar to that used by JZKit).
2154 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2155 Z39.50. But ISO/ILL was, however.
2157 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2158 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2160 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2161 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2163 --- 1.8.5 2002/02/03
2165 New YAZ client features: Command completion and new commands:
2166 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2167 Code provided by Jacob Poulsen.
2169 New call oid_trav, that visits all registered OIDs via callback.
2171 Function ZOOM_record_get now returns const char pointer rather than
2172 void pointer. It saves a lot of type casts.
2174 For YAZ client, command "auth" now allows you to set authentication
2175 in IdPass style. It is enabled when three tokens are given - order
2176 is user, group and password.
2178 Fix memory leaks in MARC record handling for ZOOM.
2180 New option for YAZ client, -k <kilobytes> that sets
2181 maximum record size. Similar to -k option for generic frontend
2182 server and yaz-ztest.
2184 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2186 Prefix query parser reports "fail" when bad attribute set is given.
2188 Fix in MARC decoder. Proximity logging. Fix for attribute set
2189 in scan handler for server. Patches by Shigeru Ishida.
2191 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2194 Configure option --with-openssl=<dir> now works when a directory is
2195 specified. Patch provided by Morten Bogeskov.
2197 New option for YAZ client, -u <auth>, that sets authentication.
2199 ZOOM fix: error information was sometimes "missing", since error
2200 was cleared/reset too when it shouldn't.
2202 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2204 --- 1.8.4 2002/01/04
2206 Scan for ZOOM API. New object ZOOM_scanset. New functions
2207 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2208 ZOOM_scanset_destroy.
2210 New ZOOM function, ZOOM_connection_last_event, that returns type
2211 of last event (such as "receive data", "send data", "apdu received",
2214 New ZOOM option, schema, that specifies schema for retrieval.
2216 New CCL feature. Qualifiers can be aliases for one or more
2217 other qualifiers (if more than one is given, OR is used).
2219 ZOOM uses named result sets if target supports it.
2221 Two new YAZ client commands: . (dot, which sources a script of YAZ
2222 client commands), and ! (to execute shell command.). Implemented
2225 Working on Debian packages.
2227 --- 1.8.3 2001/11/19
2229 YAZ client enables named result sets only if target supports it.
2231 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2233 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2234 with key="host" to get same result.
2236 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2237 Function Z3950_resultset_record(s) returns references to records
2238 "owned" by resultset. To become owner use Z3950_record_clone.
2240 Function z_ext_record handles Extended Services. Thanks to
2243 --- 1.8.2 2001/11/12
2245 CCL Parser fix: ignore token comma when dealing with and-lists.
2247 Documentation updates for COMSTACK.
2249 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2250 Changed prototype Z3950_records. For some functions, int parameters
2251 were changed to size_t.
2253 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2256 New MARC decode/display function, marc_display_exl, which properly rejects
2257 non-ISO2709 records. YAZ client uses it.
2259 --- 1.8.1 2001/10/29
2261 Fix bug: local attribute set wasn't set correctly in PQF strings.
2265 * Old Z39.50 codecs no longer supported.
2267 Added ZOOM C binding. See http://zoom.z3950.org/
2269 Renamed states for COMSTACKs to avoid confusion with events.
2271 Implemented cs_look and proper cs_rcvconnect.
2273 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2275 Configure detects POSIX threads on OpenBSD.
2277 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2278 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2280 When error is returned from present handler, non-surrogate diagnostic
2281 is returned in present response (and fetch handler is no longer called).
2283 * Minor adjustments to pquery parser (PQF). Token characters may be
2284 escaped by using backslash (C-style).
2286 PQF parser allows string attribute values to be specified. For @attr,
2287 non-numeric characters after the equal-sign are treated as strings
2288 (e.g. @attr 9=title).
2290 CCL trunction character may be defined (@truncation in file)
2292 * function zget_ExtendedServicesRequest sets waitAction to
2293 waitIfPossible (was wait).
2295 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2298 CCL operator names may be set in field definition files (CCL_bibset).
2299 See ccl/bib1 for an example.
2301 Fixes in ASN.1 compiler for C++ compatibility.
2303 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2304 and "op_or" to avoid conflict with C++.
2306 Fixed problem with GNU readline detection on Redhat 7.0.
2308 Added step-size for Scan backend handler.
2310 Fixed bug that made the frontend server crash when no attribute
2311 set was specified for scan.
2313 Front-end server automatically switches to original working directory
2314 when installed as an NT service. Previously -w had to be specified to
2317 Added extended attributes for retrieval module (data1), so that data1
2318 records carry d1_readXML/SGML attributes. d1_read also supports
2319 null-data rules ( <tag/>)
2321 On UNIX when POSIX threads are available, a separate library libyazthread
2322 is created. Programmers should link with that library and the yaz library
2323 when using threads. The reason for the split was that some applications
2324 on Linux, such as Apache, doesn't work well when using shared objects that
2327 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2328 (or any frontend server) in SSL mode by specifying ssl: followed by
2329 address. Only tested on UNIX.
2331 Added feature for CCL module. Virtual structure s=al or s=ol generates
2332 and-list and or-list respectively instead of phrase search.
2336 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2337 log_mask_str. This was done to avoid name conflicts with other libraries
2338 (such as other PHP extensions).
2340 Added raw OID member for preferred record syntax (request_format_raw)
2341 and returned record syntax (output_format_raw) for backend fetch method.
2343 Config file yaz-config now accepts options so that it returns specific
2344 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2346 Shared library support for UNIX using GNU libtool.
2348 * Modified backend interface. Request/Response struct's replaced by
2349 one read/write C struct. For example bend_fetchrequest and
2350 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2351 Every handler - even search has to be registered in bend_init
2352 handler. This means that the YAZ library no longer refers to
2353 external functions and it makes it possible to make the whole
2354 thing a single DLL/SO.
2356 Added Segment handler for backend server.
2358 Added Zmbol/Zebra administrative functions to YAZ client.
2360 Threaded frontend server on UNIX (when POSIX Threads are available).
2361 Starting the server with option -T enables multi-threading.
2365 Added configure option --enable-comp/disable-comp to control use
2366 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2367 located in sub directory asn.
2369 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2370 in ${exec_prefix}/bin along with the other programs yaz-client and
2373 GNU automake used to maintain makefiles.
2375 Added several OID's.
2377 Changed retrieval module so that we can load records with no abstract
2378 syntax defined. Tagpaths in these records are fully composed of string
2381 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2385 On UNIX, the generated makefile now supports a proper 'make install'.
2386 The prefix can be set via GNU configure to set the install location
2387 (default is /usr/local).
2389 * YAZ programs client and ztest were renamed to yaz-client and
2390 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2391 locations, such as /usr/bin,/usr/local/bin,etc.
2393 * YAZ Header files were moved from include to include/yaz. YAZ Header
2394 files are referred to as include <yaz/log.h> rather than <log.h>.
2395 The YAZ include path (-I ..) is therefore the same as before. Programmers
2396 should update their #include statements or use -Ipath/include/yaz
2397 instead. The main motivation for doing this change is that YAZ header files
2398 can be installed in "standard" locations /usr/include,/usr/local/include
2399 without introducing conflicts, since ALL YAZ header files are stored
2400 in subdirectory yaz (under /usr/include for example).
2402 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2403 rather than project/workspace files. We switched because project files
2404 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2407 Changed name of logging function, logf, to yaz_log, to prevent name
2408 clash with some math-log functions. The YAZ header log.h defines logf
2409 to yaz_log (#define) so there should be no incompatibilities by this
2412 Added bend_start/bend_stop handlers for server. These handler are
2413 called on start/stop of server. For windows they are called whenever
2414 a service is started/stopped.
2416 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2417 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2418 in util/yc.tcl. The auto-generated C code structures are, in a few
2419 cases, incompatible with the old decoders. There are differences in the
2420 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2421 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2422 The preprocessor variable ASN_COMPILED is defined when the compiled
2423 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2424 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2425 wish to use the old encoders/decoders you can specify --disable-yc
2428 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2429 version so that it supports both new - and old version of DB Update
2431 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2432 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2433 change. The name parameter can be set to 0 in which no name is specified
2434 for the construction. The macros odr_implicit and odr_explicit sets name
2435 parameter to zero for the construction involved. New macros
2436 odr_implicit_tag and odr_explicit_tag are similar to the others,
2437 except that a name parameter is added. For programmers' that don't use
2438 ODR they probably only need to change the call to z_APDU and z_External.
2440 Added access control facility by interfacing the TCP wrapper library.
2441 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2442 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2443 name of the daemon and enables the access control as specified in
2444 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2446 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2447 den Dool <H.M.vdnDool@kub.nl>.
2449 Added reference ID parameter to most functions in server API - refer
2450 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2452 Changed name of ccl library to libccl.a (was ccl.a).
2454 Fixed bug in decoder for Explain (Category TargetInfo).
2456 Added support for GNU readline in client. Thanks to Jacob Poulsen
2457 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2459 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2460 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2461 IMPLEMENTATION! This change was made to the development version before
2462 the ZIG decided to retract the amendment. If any users MUST be
2463 compatible with the original Update definition, PLEASE CONTACT US, and
2464 we will include a separate definition corresponding to the old Update
2465 ES. Note that because of the change to the ASN.1 of the
2466 TaskPackageRecordStructure we cannot define a single structure that
2467 will support both versions.
2469 * Added const modifier to buffer parameter for some ODR/BER encoding
2470 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2471 completeWAIS, odr_dumpBER.
2473 Fixed bug in client.c which caused a crash when a scanResponse didn't
2474 contain positionOfTerm.
2476 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2477 * will cause an error in a client if a non-YAZ target sends both a
2478 * list of Scan entries and non-surrogate diagnostics.
2480 Retrieval module enhancements. Tag sets may be typed in the reference
2481 to it. From the .abs-file the "tagset" directive takes a third optional
2482 integer type for the tag set referenced. From a .tag-file the "include"
2483 directive takes a third optional type as well. The old "type" directive
2484 in the tag set itself is still recognized but acts as the default type
2487 Backend interface change. Individual Scan terms returned from bend_scan
2488 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2489 in include/backend.h.
2491 Retrieval module enhancements. Multiple tag sets and attribute sets may
2492 be specified in abstract syntax specs. Revised the error/warning for
2493 logging messages reported by the retrieval module when reading the
2496 Object Identifier system (oid_..) changed. The API is backwards
2497 compatible but the oid-routines now allocates new OID's when needed.
2498 Raw OID's may be specified in oid_getvalbyname.
2500 YAZ now uses GNU configure to generate Makefile(s).
2502 * Minor changes in some of the member names of DeleteResultSetRequest and
2503 DeleteResultSetResponse. See include/proto.h.
2505 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2506 and added member 'languages' in TargetInfo (which was missing).
2508 Changed the way attribute sets are handled in the retrieval
2509 module. These are now cached, just like the abstract syntaxes
2512 Changed YAZ so that it links with compiled ASN.1.
2514 Added Explain-schema definitions and mapping routines. The following
2515 Explain categories have been implemented: AttributeDetails,
2516 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2518 Fixed minor bug in Windows version of Server Library.
2520 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2522 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2524 Added EXTERNAL: UNIverse Resource Report (non-standard).
2526 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2527 ENUMERATED and SET OF.
2529 * Added 'const' to some of the char pointer arguments for the
2530 functions, data1_read_node, data1_getelementbytagname,
2531 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2534 Fixed bug in data1_insert_taggeddata - the last_child member of
2535 parent wasn't initialised.
2537 * Changed data1_read_record and data1_read_node so that the supplied
2538 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2539 doesn't refer to any parts of the "SGML"-buffer.
2541 Fixed bug in server library (Windows version of statserv_remove).
2543 * Changed code so that it compiles as C++. The type definition
2544 of Odr_fun which is a member of Odr_arm was changed. The result is,
2545 that an explicit typecast is needed for the fun pointer when
2546 using Odr_arm - as in:
2547 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2549 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2551 Implemented the new structured date and time definition as approved
2552 by the ZIG. Added schemaId element to the specificTag in Espec-1
2553 (also approved at the last ZIG). Thanks to RVDM.
2555 Added some Object identifiers (RVDM).
2557 Changed the Update Extended Service (RVDM).
2559 Added command "refid" to client which specifies referenceId for
2560 the following requests.
2562 Implemented extended service handling for server. See ztest.c
2563 for an example as well as backend.h. New handlers are registerd
2564 in the Init handler.
2566 * Changed interface for sort in server.
2568 Added new members to statserv_options_block. It allows a server
2569 to read options from another source than just the command line. Thanks
2570 to Charles Woodfield.
2572 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2573 renamed to zboolean. Some C++ compilers complained about the name.
2575 Minor changes to gils.abs. Added index 's' (sort) on title
2576 and date/time-last-modified.
2578 --- 1.4pl2 1998/1/30
2580 Fixed bug in server library regarding inetd mode (-i). This bug
2581 was introduced by release 1.4.
2583 --- 1.4pl1 1998/1/29
2585 Added sort facility in client and backend server interface.
2587 Fixed problem with dependencies in Makefile(s).
2589 Fixed bugs for encoders/decoders of extended services and
2592 Implemented sub-tree feature for schemas. Sub-trees are
2593 referenced in *.abs-files. See explain.abs for an example
2594 of the use of this feature.
2596 Modified bib1.att; local attributes for ANY didn't include
2597 ANY itself (only affects use of the retrieval module).
2599 Fixed bug in plain SGML reader in function data1_read_node:
2600 tags with prefix "var" was incorrectly interpreted as variants.
2602 Added feature "sub-schemas" to enable references to - and definitions
2603 of - group of elements.
2605 * Removed member parent from type data1_element (in data1.h).
2607 Implemented function odr_nullval() that returns the value of
2610 * Removed member num_children from data1_node (in data1.h).
2612 Made NT service interface part of the server library. The
2613 function statserv_main uses the NT service when required and
2614 calls the statserv_start / statserv_close routines.
2616 Routine zget_SearchRequest and zget_PresentRequest fills
2617 resultSetName/Id member with "default" instead of "Default".
2619 Fixed memory leak in server. Request queue member wasn't freed.
2621 Fixed nmem_exit so that memory is freed.
2625 Revised the CCL parser utility to be thread safe.
2627 Added function, oid_ent_to_oid, to replace the function
2628 oid_getoidbyent, which is not thread safe.
2630 * Added nmem_init and nmem_exit to initialize and release
2631 NMEM resources. Function nmem_init should be called once in the
2632 initial thread before NMEM/ODR is used. statserv.c and client.c
2633 have been changed accordingly. The change was necessary to make
2634 NMEM thread safe. The NMEM memory pool is shared amongst threads
2635 in a process. Unix-based applications will still work fine without
2638 Added NT Services interface for the the Z39.50 (statserv) Server.
2639 Refer to the ztest.c source on the usage.
2641 Windows 95/NT port using MSVC5.0. Project files are included in the
2644 * Defined new 'global' handle for the retrieval (data1) system. The
2645 new handled, data1_handle, describes the state of the data1 system.
2646 This handle is passed as first argument to virtually all
2647 data1 related routines. The functions data1_create and data1_destroy
2648 creates and destroys a data1 handle respectively.
2650 Added ODR encode stream member to all backend request structures
2651 init, search, scan etc. This stream should be used to allocate all
2652 memory used for the response when thread safe operation is needed.
2654 Changed the comstack utility, cs_addstr, to be thread safe. The
2655 returned hostname string returned by the function is now part the
2658 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2659 function. The cs_straddr takes a COMSTACK handle as argument, so this
2660 function must be used after cs_create and before bind/connect.
2661 This function is thread safe.
2663 Moved test server to 'ztest' directory - generic server code still
2664 in 'server' directory.
2666 Made prefix query (pquery.c) utility thread safe.
2668 Added new function modifier YAZ_EXPORT to 'export' public DLL
2669 functions when using windows (see include/yconfig.h).
2671 Added definitions to the OID database (util/oid.c) (RVDM).
2673 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2675 Added call to ccl_rpn_delete in client program.
2677 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2678 release of RPN structure.
2680 Added support for C++, headers uses extern "C" for public definitions.
2681 With input from RVDM.
2683 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2684 Thanks to Ronald van der Meer (RVDM).
2686 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2688 Added support for private extensions to the OID database
2689 (oid_setprivateoids()). Thanks to RVDM.
2691 Added optional, physical ANY (key replication)
2693 Fixed null-reference problem in GRS-1 output filter.
2695 Proximity operator added to Prefix Query Format (PQF).
2697 In test client command "base" accepts multiple databases.
2699 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2703 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2705 Smallish bug-fixes in the new encoders/decoders (explain).
2707 Bug fixed in DeleteRequest.
2709 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2711 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2713 Added SOIF syntax (using private OID for now) to retrieval module and client.
2715 Added Update extended service.
2717 Added SearchResult-1 additional info structure.
2719 Added optional CCL (ISO8777) interpreter as separate module. Available
2722 --- 1.2 1996/6/10 (1st anniversary release)
2724 Added Summary record syntax. Lightly tested.
2726 Added OPAC record syntax. Untested.
2728 Added ResourceReport service encoders/decoders. Untested.
2730 Fixed bug in z_Unit - wrong tagging on unitSystem.
2732 Fixed bug in the DiagRecs decoder.
2734 Added options for max PDU size and session timeout to frontend-server.
2736 Added documentation of query-language parsers and other supporting utilities.
2738 [frontend-server] Added Attribute set to the bend_scanrequest API.
2740 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2741 surrogate diagnostics were generated.
2743 [retrieval] Allow multiple local values for attribute.
2745 [retrieval] Allow multiple attributes per element in .abs files. index type.
2747 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2749 --- 1.1pl2 1996/4/10
2751 Minor changes, mostly specific to Zebra's requirements (retrieval)
2755 Repaired bug in frontend server when running multiple listening
2756 endpoints in dynamic mode.
2758 z_External() now won't break if a known, ASN.1 value comes encapsulated
2759 in an octet-string. The value will pass through unmodified in an Odr_oct.
2761 Added a bit of code to the demo client to decode & display
2762 ASN.1-structured records represented in the octet-aligned branch of
2763 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2765 Added z_ext_getentbyref() to the ASN module. Doc updated.
2767 * Completed the SCAN definition in the ASN module. This may break SCAN
2768 code based on older YAZ-versions at compile-time. The fix is easy -
2771 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2772 under the SCAN definition. Remember to initialize this, server-people.
2774 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2775 that this does not extend to ODR and ASN.
2777 Comstack allows insertion of established socket (primarily for
2778 inetd-operation of servers). Doc updated.
2780 Front-end server can now start from the inetd in TCP mode. Doc
2783 --- 1.0pl4 1996/1/24
2787 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2788 the rank and record number.
2790 Adjustments to the frontend server.
2792 Fixed diagnostic BER dumper. It ignored the file argument.
2796 Various changes to retrieval module.
2798 Changed the union discriminators of the protocol files from enums to
2799 ints paired with #defines.
2801 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2804 *Changed operator in the RPN structure to 'roperator', again to avoid a
2807 Fixed problems in Explain decoders/encoders.
2809 --- 1.0pl2 1995/12/6
2811 Memory bug in log module fixed.
2813 --- 1.0pl1 1995/12/5
2815 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2817 Bug in Explain DatabaseInfo module fixed.
2819 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2823 The shift to v1.0 signals that we now consider the *core* functionality
2824 of YAZ reasonably stable (the core being more or less equivalent to
2825 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2826 tested (Explain not at all - though that will happen soonish).
2828 Minor changes to code to support Windows port.
2830 Various minor changes after we're getting to use GRS-1 & co. more.
2832 Added Espec-1 format.
2834 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2835 of the protocol and it cannot be selected when encoding (maps into 'string'
2836 when decoding). Needed to talk to some servers.
2838 Demo client can request simple element set names.
2840 Added Diagnostic Format encoders/decoders.
2842 Added simple Close handling to frontend server (no hooks for resource
2843 reporting yet), and demonstration client.
2845 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2847 --- 1.0b3 1995/08/24
2849 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2850 handled incorrectly when records were requested in the searchResponse. This
2851 will only affect you if you use the frontend-server.
2853 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2854 Test-client will ask for and print GRS1. Ztest will return dummy records
2857 Added Explain encoders/decoders to the service-level API. Untested.
2859 Added Extended Services: Item Order encoders and decoders to the Service-
2860 level API. Untested. We could use a recent copy of the pertinent bits
2861 of the ILL protocol to add those bits.
2863 Added diagnostic format 1 encoders/decoders to the service-level API.
2866 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2867 odr_cons.c, which causes a more correct output.
2869 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2870 was always set to 0 when no records were requested in the searchRequest.
2872 * Added better external-handling. This shouldn't harm old code that
2873 *encodes* externals. It can break code that looks for a
2874 'single-ASN1-type' representation, since those types that are known
2875 are now decoded immediately. Look at the SUTRS sample code in
2876 seshigh.c and client.c. Documentation updated.
2878 Handling of structured records in bend_fetchresponse. Length -1 marks
2879 structured record, type is deduced from format field.
2881 --- 1.0b2 1995/06/27
2882 Fairly quick maintenance release to add SUTRS support.
2884 Fixed handling of SUTRS records in the demonstration client.
2886 * Added format field to the bend_fetchrequest and bend_fetchresponce
2887 structures of the backend API (frontend server). When the record is
2888 returned, the value of the format field is mapped to an OID. The
2889 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2890 of the record. The special value VAL_NONE in the bend_request means
2891 that no specific format was requested by the client. Documentation
2892 updated accordingly. Test server (ztest) will return a fixed dummy
2893 SUTRS record if your client requests SUTRS.
2895 Documentation updated accordingly.
2897 You can now set external libraries and RANLIB support in the top-level
2901 First public release.
