1 Add support for extra request / response data for SRU codecs and GFS.
2 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
3 for extra data response buffer and length. For the GFS, both request
4 and response data (XML) is carried in extra_args and extra_response_data
5 for the search handler. Patch by Ko van der Sloot.
9 Make a number of functions defined in xmlquery.c static. These have
10 never been declared in a public header file (yaz/xmlquery.h) and was
11 made public by mistake.
13 Improve speed of character conversions (iconv utilities). This makes
14 conversions from MARC-8 faster.
16 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
17 unless type desired is "raw". This will prevent type "xml" from
18 returning ISO2709 .. Which obviously can not be XML parsed.
20 Fix memory leak in ZOOM that would occur if option apdulog was used
21 on a re-used connection.
23 Frontend server logs HTTP requests.
25 Frontend server now sends Z39.50 close when it times out (sesssion has
26 been idle for too long). Versions 2.0.30 and earlier also sent close.
27 But due to a mistake this was disabled in all versions after that, i.e.
28 the server would just close the socket immediately.
30 yaz-client emits a better message when receiving an unrecognised
33 Skip zero-length subfields when decoding ISO2709. This rare case happens
34 if a record has two FS characters in a sequence. Without this patch
35 there would be a reference beyond char array in using_code_len fragments
38 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
42 The show command offered by the zoomsh command now takes a 3d optional
43 parameter type which is what is passed to ZOOM_record. If the type
44 argument is omitted, "render" is used.
46 RPN to CQL conv may use USE string attributes (bug #2978).
48 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
52 Function yaz_xml2query allows a diagnostic element in the PQF XML
53 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
54 code and additional info respectively.
56 The BER BOOLEAN is now the integral type Odr_bool which still happens
57 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
58 typedef'd to Odr_int. This is still an integral 'int', but it may be
59 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
60 ASN-1 compiler as well as programs has been updated to use the new types.
64 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
65 only the bibliographic record was rendered. For type=opac, an OPAC
66 record is only returned if it is present.
68 iconv: small fix for encoding of advancegreek.
70 yaz-client: avoid double display of SRU/SRW records (bug #2798).
72 yaz-client: option auto_reconnect=on really reconnects.
74 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
76 server: avoid null ptr ref for for yaz_poll errors.
78 build: fix RPM build for RHEL 5.3.
80 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
84 Fixed bug #2709: TCP connect returns Invalid argument.
86 Fixed compilation for mingw.
88 Honor charset for raw records (ZOOM_record_get).
90 Fixed use of errno for threaded mode that was seen on Solaris 10.
92 Fixed argument passing with blanks in value for Windows Service.
94 Disable YAZ' own log rotate by default (no 1 GB limit).
95 The variable l_max_size which specifies the log file limit is set to 0
96 (DISABLED): This is due to the fact that YAZ is most often deployed using
97 logrotate. Also YAZ can not perform log rotate because of unsufficient
100 --- 3.0.44 2009/02/17
102 List supported encodings in man page for yaz-iconv.
104 Fixed missing SSL libs for --libs output
106 Re-established OID record syntax application-xml. Nobody should use it
107 but we don't want to change soname because of this symbol being absent.
109 --- 3.0.42 2009/02/02
111 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
113 Added member named_result_sets for init handler struct for the GFS. This
114 allows a server to disable named result sets.
116 Removed OID record syntax application-xml.
118 Added support for rule-based transliterator for ICU wrapper of YAZ.
120 Fixed bug #1902: yaz-icu XML output.
122 Make YAZ checks Emacs friendly.
124 BITSTRING value shows value. Bug #2346.
126 ISO2709 decoding: skip control characters from indicator data.
128 Omit sort key by default in yaz-icu's output.
130 Allow combined single char options (again) for YAZ' options function.
132 Utility yaz-marcdump got option to display YAZ version (-V).
134 Allow YAZ to use ICU 3.4.
136 Added new ICU test case which illustrates removal of diacritics.
138 --- 3.0.41 2008/12/29
140 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
142 --- 3.0.40 2008/12/29
144 For configure, using option --without-xml2 also disables Libxslt/Libexslt
147 Fixed bug #2352: yaz-marcdump crashes for certain record.
149 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
151 Added support for Danmarc2 to UTF-8 conversion.
153 Added support for ISO5426 to UTF-8 conversion.
155 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
156 implementation version.
158 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
160 --- 3.0.38 2008/11/10
162 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
163 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
165 ZOOM C now interprets databaseName option for ZOOM connection as path
168 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
170 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
172 Dummy Libxml2 types no longer defined in headers of YAZ'.
174 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
177 --- 3.0.36 2008/09/26
179 Various ODR chapter fixes.
181 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
183 Added missing source for Windows compilation, mutex.c.
185 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
187 For SRU connections in ZOOM all records up to "count" are now fetched.
189 Fixed crash in generic frontend server (and yaz-ztest) which occurred
190 in Windows due to bad error handling for Libxml2.
192 Added facility for sending arbitrary records (ASN.1 any) using
193 ZOOM C's Extended service update. Patch by Sam Reynolds.
195 New options for ZOOM C's connection, logapdu which makes ZOOM log
198 --- 3.0.34 2008/06/18
200 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
202 --- 3.0.32 2008/06/12
204 Fixed memory violation that could occur when decoding UTF-8. This bug
205 was only present in 3.0.30 of YAZ.
207 --- 3.0.30 2008/06/06
209 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
210 GNU TLS is used by default (if found).
212 yaz-ztest returns OPAC records if a client asks for OPAC.
214 Improved speed of MARC-8 encoding.
216 Added support for lossy and loss-less MARC-8 encoding.
218 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
220 Added new Windows Service wrapper (sc).
222 yaz-client's itemorder command may now send a file.
224 Fixed yaz-marcdump to allow the use of NS prefix for record element.
226 Added new function yaz_log_xml_errors.
228 Allow (but warn) unknown XML attributes in MARCXML parsing.
230 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
232 The UTF-8 to MARC-8 conversion now uses a different set of characters
233 for Greek symbols. Bug #2120.
235 --- 3.0.26 2008/02/21
237 Added yaz_daemon (daemon.h).
239 Fixed bug #2068: pkg-config trouble
241 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
243 --- 3.0.24 2008/01/28
245 Document --with-xml2 option.
247 Added OPAC XML XSD (etc/opacxml.xsd).
249 Allow glob mask for name attribute in retrieval element for the
250 generic frontend server's retrieval facility.
252 Changed yaz_poll_poll to return yaz_poll_except for all returned events
253 except POLLIN/POLLOUT.
255 Fixed error handling in cs_listen. Bug #2037.
257 --- 3.0.22 2008/01/20
259 Fixed version in yaz/yaz-version.h.
261 Fixed bug #2027: Crash when closing connection.
263 Changed configure so that ICU support is only enabled if only ICU
264 and Libxml2 is available (because the ICU chain is XML based).
266 --- 3.0.20 2008/01/15
268 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
269 is built. Only this DLL depends on the ICU runtime.
271 yaz-ziffy is no longer part of YAZ. It is distributed separately by
272 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
274 Changed license of CCL module to 'Revised BSD'. After consultation with
275 remaining members of the original EUROPAGATE consortium, we are re-issuing
276 the CCL module without a separate license. The software was developed by
277 Index Data as part of a research project. The special license was included
278 to help feed usage information back to the project consortium to support
279 project evaluation. At this time, the project consortium has long-since
280 disbanded, and the majority of the original principals have retired. At the
281 same time, we have significantly modified the software during the following
282 years, to the point where very practically no original code remains. To
283 simplify re-use of the software, we have contacted those members of the
284 consortium who could be reached, and agreed to re-issue the module as a
285 proper part of the YAZ package.
287 Tcl scripts uses /usr/bin/tclsh as preferred shell.
289 CQL closer to being version 1.2 compliant. CQL also allows free-form
290 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
293 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
294 bug could make Extended services handling crash in the ZOOM layer. This
295 bug was only present in YAZ 3.0.18.
297 --- 3.0.18 2007/12/19
299 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
302 yaz-marcdump reads and writes collection wrapped records.
304 Handle OPAC for record conversion module.
306 Fixes for ICU wrapper.
308 Allow ICU libs to be controlled with --with-icu .
310 --- 3.0.16 2007/11/12
312 Added yaz_poll which is a wrapper for select/poll. When poll is available
313 and non-buggy, it is used, by yaz_poll . This allows more than 1024
314 sockets to be in use.
316 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
317 functionality through an XML based configuration (ICU chain). This system
318 is useful for search facilities such as Pazpar2 and Zebra that needs to
319 perform tokenization of indexed material. The ICU code in a separate
320 library libyaz3_icu.a.
322 Added HTTP tunnel facility for COMSTACK, bug #1752.
323 This is a facility that allows a Web proxy, such as squid, to tunnel
324 Z39.50 traffic. This facility is "transparent" to must applications
325 using YAZ. It's enabled by using pseudo transport connect: followed by
326 the proxy address, followed by command, then follwed by he regular
327 "virtual" addresss. For example,
328 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
330 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
332 --- 3.0.14 2007/09/21
334 Fixed bad memory reference in ZOOM_record - cuased by member not being
335 initialized. This was a problem only in YAZ 3.0.12.
337 Fixed bug in conversion from MARC to XML: Non-XML characters in control
338 fields were not removed.
340 Changed the way C code is generated from codetables.xml. Made a MARC-8
341 conversion trie for each characterSet section rather than codeTable.
342 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
343 of codetables.xml from Larry Dixson, LOC. Bug #1464.
345 --- 3.0.12 2007/09/12
347 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
348 from ZOOM_record_error).
350 ZOOM C function ZOOM_record_get returns record schema for type="schema".
352 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
354 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
356 Better SRW-to-Bib-1 diagnostic mapping.
358 ZOOM C and yaz-client announces SRU version 1.2 by default.
360 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
363 Fixed in yaz_sru_decode to allow other version than 1.1.
365 --- 3.0.10 2007/08/22
367 Added support for SRU scan for ZOOM.
369 Added support for the use of the older versions or Extended Service
370 Update in ZOOM. To faciliate this, an option "updateVersion" may be
371 set to the version , 1=first, 2=second, 3=third. The third version is
372 what ZOOM C has used so far. And that, obviously, is the default.
374 Added support for CCL queries in Z39.50 queries sent to the GFS (and
375 therefore in Zebra and in SimpleServer-based applications). The new
376 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
377 qualifier file used to transform incoming CCL queries into Type-1 RPN,
378 which is passed into the back-end search callback function.
380 Added support for HTTP Basic authentication in clients: the SRU/W
381 codec encodes the username/password elements of the PDU structure
382 appropriately, and these may be set using the "user" and "password"
383 options in ZOOM-C applications (the same options that are used for
384 Z39.50 authentication).
388 Fixed bug #1208: SSL appears to be broken in ZOOM.
390 Fixed bug #1206: Libxml2 include path weirdness.
392 Added oid_name_to_dotstring.
394 Allow elementSetName to be specified for ZOOM C record update.
396 Allow waitAction to be specified for ZOOM C based for Extended Services.
398 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
399 syntax OID. Bug introduced in YAZ 3 series.
401 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
405 Fixed bug #1157: yaz-client does not read .yazclientrc from current
406 directory. yaz-client now reads commands from file given by option -f
407 if specified; then tries to read .yazclientrc in current directory.
408 Failing that, it reads .yazclientrc from user's home directory.
410 Added support for correlationInfo Note and ID for Record Update via
413 Added yaz-client command querycharset which specifies character set for
414 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
415 (termListAndStartPoint).
417 Charset ISO5428:1984 is an alias for ISO5428-1984.
419 Implemented a way to perform scan in a result set using Z39.50. This
420 is achieved by attaching the result set name in the characterInfo
421 (type InternationalString) of OtherInformation in the Scan Request PDU.
422 The result set is identified in the otherinformation by the new OID:
423 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
424 This allows for scan in result set and faceted search . Zebra did some
425 of this in the APT term using attribute type 8 and value being result
426 set. Using the OtherInformation approach for this is cleaner and easier
427 to work with in proxies and the like. This facility can be used in
428 yaz-client using new command setscan which takes a result set as first
429 argument, start position (APT) as second.
431 Changed decoding of SRU XML packed records to deal with servers that
432 have recordData with XML data with multiple root nodes. Also make
433 comparison for recordPacking case insensitive. Again, one server
434 returns "XML" where others return "xml".
436 For SRU responses allow Content-Type application/xml as well as text/xml.
440 Fixed bug in character set conversion of BER strings. Bug introduced
445 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
447 For OID class, use oid_class consistently.
449 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
452 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
453 character set for bibliographic information interchange". By Giannis Kosmas.
455 Added documentation on new OID API.
459 Changes to generic frontend server interface: added new member
460 'query_charset' for bend_initrequest structure. A backend init handler
461 should set this member to its native character set for query terms.
462 When defined, the frontend server logic will announce this character set
463 to a client if the negotiationModel bit is set by the client. All server
464 implementors are encouraged to specify this. If a backend server does not
465 specify this a warning is issued using yaz_log(YLOG_WARN,..).
467 Added CCL utility to remove terms (stop words) from resulting RPN
468 tree. This is handled by functions with prefix ccl_stop_words_ .
470 New ZOOM C option, "rpnCharset", which allows client-side conversion of
471 terms in RPN queries.
473 Clean-up the CCL API. Moved some internal structures from ccl.h to
474 private header cclp.h. Changed ccl_parser_create so that a Bibset must
475 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
476 This is replaced by ccl_parser_find_str which takes a string instead.
478 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
479 libyaz.la is the core of YAZ except the generic frontend server and
480 does not depend on POSIX threads anymore. libyaz_server.la is the
481 generic frontend server facilities and uses POSIX thread functionality
482 if available. The libyaz.la no longer depends on POSIX threads because
483 the number of global structures is limited. NMEM no longer re-uses blocks
484 between threads ; it simply free's memory immediately but allocates in
485 "large" chunks as usual. We don't expect any performance penalties
486 because of this. The yaz_log system is still using a global log_level so
487 caution must be taken when modifying it with yaz_log_init_.. +
488 yaz_log_mask_str. This, however, should not cause any trouble because
489 these functions are called during initialization of application code
490 anyway. `yaz-config --libs server` returns libs for server applications;
491 `yaz-config --libs` returns libs for non-server applications.
493 New OID database - with public definitions in oid_db.h. Removed old OID
494 database including the head oid.h and definitions such as enum oid_value
495 and struct oident. The new OID database uses the same string names as
496 before but the 'protocol' is gone. There are now only two representations
497 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
498 converts from string to OID; functions with prefix yaz_oid_to_string
499 converts the other way.
501 Change to emit_term() in CQL-to-PQF query translation: when a term has
502 the /regexp relation modifier, do not process it for leading and
503 trailing "^" and "*", which have quite different meanings in regular
506 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
507 write handlers no longer carries a 'last' parameter. This will make
508 yaz_iconv flush "less" characters. A flush is performed by call to
509 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
511 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
512 removed, because function yaz_query_to_wrbuf does the same.
514 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
515 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
517 Deprecated MARC utility functions removed.
519 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
522 Branch split: YAZ_2_1_55_branch
524 --- 2.1.54 2007/03/16
526 Fix to ZOOM-C so that transparent reconnection is properly handled on
527 connections that are in asynchronous mode.
529 Fixed compilation on OpenBSD 4.0.
531 Large strings in GRS-1 records are now properly displayed in yaz-client.
533 Added character conversion support for "advancegreek"; based on patch from
536 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
537 sequence is met. Before the error was not set so it would be unknown.
539 Adjust yaz-marcdump MARC reader so that it skips until record separator
542 --- 2.1.52 2007/03/07
544 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
545 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
546 fd_set structure used as a bitmask for the FDs to be selected on.
548 Using ACX_PTHREAD macro to check for POSIX threads.
550 Fixed have-vsnprintf check.
552 --- 2.1.50 2007/02/23
554 Fixes for configure on BSD. Bug #900.
556 Added snprintf/vsnprintf wrappers for systems that don't have
557 limits (heavens forbid).
559 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
560 created before all previous tasks were completed and removed from the
561 task queue, the new task could be removed by a mistake.
563 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
565 Implemented pass-through CQL-to-PQF conversions. Bug #861.
567 Fixed bug #832: Problem with MARC/charset in yaz-client.
569 Fixed bug #668: save command line history for yaz-client.
571 Fixed bug #830: pkg-config support.
573 --- 2.1.48 2007/01/23
575 Extended ZOOM result set options with two options that may be read by
576 a client: resultSetStatus and presentStatus with values as specified for
578 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
580 Fixed bug #827: Using SSL fails on Debian etch.
582 Fixed bug #826: Weird looking chars for set of MARC records.
584 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
585 that is treated as an ItemOrder with itemRequest being an XML document
586 external. The value of "doc" is the content.
588 Extended the GFS search facility. New member of bend_search_rr
589 'estimated_hit_count' signals that hits is known to be an estmate
590 (higher or lower than real hit count). New member 'partial_resultset'
591 signals that the search was partial (hit count is lower or equal than
592 real hit count). For Z39.50, the information is stored in resultSetStatus
593 member of SearchResponse APDU. For SRU, the information is signalled
594 via SRU diagnostic 59: "Result set created with valid partial results
597 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
599 --- 2.1.46 2007/01/13
601 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
603 Added ZOOM_connection_peek_event.
605 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
606 the following new functions:
607 ZOOM_event_nonblock, ZOOM_connection_process,
608 ZOOM_connection_get_{socket,mask,timeout},
609 ZOOM_connection_fire_event_{timeout,socket}.
610 The existing blocking event handler, ZOOM_event, is a wrapper for the
611 + blocking ZOOM_event_sys_{poll,select}.
613 Implemented function ccl_xml_config which parses XML version of CCL
614 configuration (bug #798).
616 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
618 Added timings utility (yaz/timing.h)
620 --- 2.1.44 2007/01/03
622 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
625 Fixed bug #779: Rotation of apdu.log fails.
627 Fixed for character set conversions:
628 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
629 Honor G1 set in MARC-8 decoding.
631 --- 2.1.42 2006/12/17
633 Fixed bug #775: char conversion does not handle Alternative UTF-8
636 Implemented function yaz_marc_read_line which parses MARC line format
637 records. There is a wealth of formats out there. So far, this function
638 reads line records produced by yaz_marc_write_line.
640 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
641 more generic and easier to remember(!) options: -i format and -o format
642 which specifies input format and output format respectively - where
643 format is one of "marc", "marcxml", "line", "marcxchange".
645 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
646 does not print anything except warnings for records.
648 For yaz-marcdump, added support for MARC split into files (-s) with a given
651 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
652 spec, at http://www.loc.gov/standards/sru/record-update/
653 This has changed the binary layout of the following structs:
654 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
655 bend_update_rr . Patch by Ko van der Sloot.
657 Added GFS utility function bend_assoc_is_alive which returns 1 if
658 association is still alive (client is connected); 0 otherwise (client
659 closed connection). This allows busy servers to stop working for
662 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
663 been a separate piece of software. This version of ziffy has been modified
664 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
666 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
668 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
669 Client code may now interrogate options such as "init_opt_sort" to
670 find out whether the server claims to support various options.
672 --- 2.1.40 2006/11/27
674 Added utilities yaz_{set,get}_esn to set/get element set name from
677 Removed the build of libyazthread.la. The libyaz.so is the threaded version
678 of YAZ and has been so since YAZ 2.1.10.
680 Implemented ZOOM_record_error which returns error information for
681 record (surrogate diagnostic).
683 --- 2.1.38 2006/10/31
685 Updates for SRU Update by Ko van der Sloot:
686 1. Changed name from "operation" to "action"
687 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
688 versions in the code, marked as 'backward compatible'.
689 3. Added diagnostics for SRU Update.
691 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
693 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
695 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
697 For GFS, fixed problem with SRU diagnostic 'First record position out of
698 range' being issued for 0 hits.
700 zoomtst10 part of Windows Build.
702 --- 2.1.36 2006/10/13
704 Implemented yaz_filepath_comp which splits a path into file path
705 components (required by Zebra 2.0.3+).
707 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
708 BSD inspired license until now so this should not have any real impact on
709 anybody. See http://www.opensource.org/licenses/bsd-license.php
711 Fixed bug #687: Missing log lines.
713 Fixed bug #678: CQL to PQF translation does not preserve double-quote
716 Fixed bug #689: SRU diagnostics to be added.
718 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
719 whether a connection is idle (no more work do do).
721 --- 2.1.34 2006/10/04
723 Change type of optval from long to int for invocation of setsockopt with
724 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
726 Added support for specifying the max log file size for the Generic
727 Frontend Server. The size is given with option -r.
729 --- 2.1.32 2006/09/21
731 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
733 --- 2.1.30 2006/09/17
735 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
738 Fixed bug in Generic Frontend Server that could cause a server to stop
739 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
741 For the generic frontend server, the maximum record size is used as maximum
742 size of incoming packages (SRU + Z39.50). The value until was previously
743 only used in Z39.50 Init negotiation and, later, in a session controlled
744 sizes of records returned. This is controlled using -k option. It can be
745 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
747 --- 2.1.28 2006/09/04
749 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
752 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
754 New option for yaz-marcdump -lpos=value which allows setting a portion
755 of MARC header to a certain value.
757 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
759 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
760 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
762 --- 2.1.26 2006/08/15
764 Fixed problem with SRU mode type (soap, get, post) for yaz-client
767 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
769 --- 2.1.24 2006/08/08
771 Fixed MARC ISO2709 encoding routines to deal with character set
774 Minor changes to GFS logging. Database included in search request log
777 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
778 cached/multiple records.
780 Shared libraries are built by default on Unix+configure.
782 Changed cql2pqf transformation to use a different evaluation order. The
783 new order is: always, relation, structure, position, truncation, index
784 and relationModifier. Old order was: always, relation, relationModifier,
785 structure, index, position, truncation. Note that the the latter ones
786 override former ones for identical attributes.. The new scheme means that
787 it is possible to override any existing attribute with a relationModifier.
788 And also that it is possible to override everything for the index rule
789 (except the ones listed in relationModifier). No order is perfect but this
790 one, we believe, covers more real cases.. The "always" should have been
791 called "default", since the attributes there can be overridden with all
794 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
795 compilation phase, but also for yaz-config --cflags output. This allows
796 us to have public headers with Libxml2 stuff in them . It should also,
797 eventually, make Libxml2 checks redundant in packages using YAZ, such
800 --- 2.1.22 2006/06/15
802 Changed SRU update structure bend_update_rr so that SRU diagnostics are
803 stored in uri, message and details.. Previously diagnostics were stored
804 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
805 compatibility.. but he's probably the only one affected, so.
807 Added support for CCL, compiled on the client side, in ZOOM-C. This
808 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
809 input; the resulting query objects can be used for for searching with
810 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
812 YAZ' configure searches for OpenSSL by default.
814 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
815 SL_CTX_use_certificate_file. See
816 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
817 for more info. Thanks to Ko van der Sloot.
819 --- 2.1.20 2006/06/02
821 Bug #600: SRU GET, POST support for yaz-client. Introduced
822 command 'sru' which selects method SOAP/GET/POST.
824 Allow missingValueAction to be specified for the sortspec string -
825 function yaz_sort_spec. By default, the missing value action is null.
826 Use ! to specify "abort". Use = followed by stringvalue to specify default
829 Ensured that Present-handler (if defined) is called in GFS before any call to
830 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
831 searchRetrieve requests.
833 Documentation for YAZ is now based on the Docbook XML/XSLT using
834 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
835 is no longer depending on jade/openjade or docbook-to-man scripts.
836 PDF is no longer part of the distribution - but can optionally be
837 made using DSSSL/jadetex or FOP.
839 Added retrieval handling support in Generic Frontend Server to support
840 conversion between MARC/XML as well as XSLTtransforms. See
841 etc/yazgfs.xml for an example.
843 Added Authentication support to Generic Frontend Server in SRU
844 mode. Authentication using HTTP Basic is supported, as is the use
845 of 'x-username' and 'x-password' parameters in the request itself.
847 Added support for a new character set MARC8s identical to MARC8 except
848 that it converts combined characters to single Unicode characters in the
849 Latin-1 range (when possible).
851 --- 2.1.18 2006/04/24
853 ASN.1 compiler 0.4: generates brief Doxygen file header for
854 generated .h/.c files.
856 Utility yaz_iconv now supports conversion to MARC-8.
858 New facilities for the MARC module. The reading - and writing of
859 content are separate methods for the yaz_marc_t handle. The following
860 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
861 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
862 format). Write functions have prefix yaz_marc_write_.. The existing
863 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
864 available. Removed support for OAI-MARC and simplexml (not the
865 simplexml from PHP5).
867 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
868 to be returned for this connection.
870 --- 2.1.16 2006/03/31
872 Allow multiple languages and charsets to be specified with
873 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
874 negcharset iso-8859-1,utf-8
876 Translation of proximity nodes from CQL into PQF now works.
878 Moved to automake 1.8, 1.9.
880 Added function yaz_log_set_handler which allows a log handler to be
881 installed. This handler will be called for all log messages. Output
882 to file is also produced; but that can be disabled by passing NULL
883 fname to yaz_log_init_file.
885 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
887 For SRW (including GFS), accept application/soap+xml as content-type
890 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
891 produces NO stylesheet reference even if a default stylesheet is specified
894 --- 2.1.14 2006/03/14
896 Updated Windows package to include yazd.dll + yazd.lib for the
897 Development component.
899 If the environment variable YAZ_LOG is set, then it is used as a
900 string indicating the default level of logging to use if not
901 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
902 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
903 used as before. So, for example, to omit warnings from YAZ logging,
906 cql_transform() now map structure and other attributes before indexes,
907 so that index-specific structures and other attributes can override
908 defaults. So now a combination of mapping specifications such as:
910 index.dc.date = 1=date-modified 4=5
911 does the right thing.
913 cql_transform() now also respects the "always" mapping specification,
914 which establishes an initial set of attributes to be used for all
915 terms except where overridden by more specific attributes associated
916 with the index, relation or modifier.
918 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
919 which mode to use; one of "post", "get" or "soap" (SRW, default).
921 Fixes for yaz_iconv routines: changed trie-based character set conversions
922 to use only non-negative values for bit fields due to Sun's C compiler not
923 supporting negative values.
925 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
926 sequences where not read correctly. Fix by Rustam Usmanov.
928 Updated win/makefile to use options, settings which makes things
929 compile with VS C 2005.
931 --- 2.1.12 2006/02/01
933 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
935 In ZOOM socket code, use select instead of poll on MacOSX.
937 ZOOM-C now support client-side compilation of CQL into RPN that is
938 sent to the server, enabling CQL to be used against all Z39.50
939 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
940 ZOOM_query object, and submit it using ZOOM_connection_search().
941 The CQL-to-RPN translation uses a configuration file, the name of
942 which must be specified in the Connection's "cqlfile" option.
944 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
945 function, which takes as its start-term parameter a ZOOM_query object
946 (which may have had either CQL or RPN set into it).
949 --- 2.1.10 2005/11/29
951 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
952 GFS to support this as well. Backend handler, bend_srw_update, does the
953 update work. Code contributed by Ko van der Sloot.
955 Allow retrieval of Search Result-1 information in ZOOM by the use of
956 options that are attached to a result set. ZOOM documentation updated
959 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
960 UTF-8 conversion. Patch by Raj Patel.
962 Added option -m to GFS to control formatting of timestamps in log file.
964 Added 'exit' as synonym for 'quit' in yaz-client
966 Added support for specifying SRW resultSetId + resultSetIdleTime in a
967 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
968 for the new members. Patch by Ko van der Sloot.
970 Added support for SRU POST. It is supported for content-type
971 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
973 Do not build the separate Multi-threaded (MT) library libyazthread.la.
974 Instead make the library libyaz.la multi-threaded. Threading as a whole
975 can still be disabled by configure option --disable-threads. Previosly,
976 with older GLIBCs there were problems with MT libs under Apache. This
977 has now been fixed a long time ago.
979 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
982 CQL module modified to be case insensitive for relations/indexes/operations.
984 Fixed bug in CQL transform code: incorrect value relationModifieder
987 Added 'show all' command for yaz-client which retrieves all results
990 Added new yaz-client, xmles, which takes a (private) OID and
991 a document to be sent as an extended service request.
993 Describe new yaz-client commands wait_response and set_auto_wait.
995 Increase TCP/IP listener backlog from 3 (which I am guessing was
996 copied from the SunOS manual entry way back when) so SOMAXCONN, so
997 that the socket will queue as many incoming connections as it's able
998 to handle ongoing connections. In other words, it will never now
999 refuse a connection that it would be able to handle merely because
1000 it's not got around to accepting() enough of the pending connections
1001 yet. This is the behaviour anyway under Linux, where the listen()
1002 argument is ignored; but not under BSD and on systems such as
1003 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1004 YAZ-based servers should now be uniform across operating systems in
1007 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1008 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1009 This allows yaz-marcdump to read large MARC batches (>2 GB).
1011 Modified all YAZ source files - except the source which is auto-generated
1012 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1015 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1016 corresponding to the existing *_setl() function. These allow option
1017 values containing arbitrary valuues.
1019 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1020 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1021 except that it returns an indicator of whether or not the sort
1022 criterion was accepted (0 for OK, -1 for invalid).
1024 --- 2.1.8 2005/06/07
1026 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1027 MARC output rather than returning "new" buffer.
1029 yaz-client warns about unknown init options.
1031 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1033 --- 2.1.6 2005/05/24
1035 Added support for SRW sort in Generic Frontend Server. Patch
1036 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1037 sortKeys - or NULL if none is provided.
1039 Fixed bug #307: It was impossible to specify indefinite/no timeout
1040 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1043 Added support for multiple languages and charsets to be specified in
1044 ZOOM. Each charset/language is separated by a blank. If negotiation is
1045 in effect in init-response, Option
1046 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1047 Code based on patch by Vasiliy Osadchuk.
1049 Fixed bug #306: infinite recursion that occurred when calling
1050 yaz_log_level_init as the first call (before other log level or
1053 Fixed bug in scan handling in front end server: if preferred-Position-In-
1054 Response was non-present, a NULL pointer referece was performed.
1056 --- 2.1.4 2005/04/26
1058 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1059 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1060 now defined for all those error codes. So instead of putting 109 in
1061 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1062 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1064 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1067 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1069 Program yaz-client now exits and produces an error message if multiple
1070 Z39.50 servers are specified on the command line (none or one allowed
1073 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1076 --- 2.1.2 2005/03/16
1078 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1080 Fixed bug #272: Preserve spacing for CCL terms.
1082 --- 2.1.0 2005/03/14
1084 Added support for virtual hosts and multiple backend servers for
1085 the YAZ frontend server. The configution is XML based and
1086 support specificition of CQL to RPN mappings and explain information.
1087 See section "Virtual Hosts" in the YAZ manual.
1089 Extended OPAC display utility. OPAC display utility renders
1090 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1091 to supplement yaz_marc_decode_wrbuf.
1093 Fixed a bug in MARC decoder that could caused it to crash for some
1094 invalid MARC records. More diagnostics and warnings where added in
1095 XML output (warnings, etc are stored in comments).
1097 --- 2.0.34 2005/02/08
1099 Fixes for UNIX domain sockets. Bug #261.
1101 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1103 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1104 Added yaz_marc_subfield_str which defines subfield lead string which is
1105 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1106 yaz_marc_endline_str which defines end of fields string used in
1107 YAZ_MARC_LINE format. Default string is newline.
1109 Experimental support for MarcXChange. This format can be produced
1110 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1111 http://www.bs.dk/standards/MarcXchange.xsd
1113 Added yaz-client commands scansize that sets maximum number of
1114 entries to be returned by scan.
1116 --- 2.0.32 2005/01/11
1118 Added support for SRW scan in yaz-client and Generic Frontend Server.
1120 * Added whereInList member to SRW Scan Term.
1122 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1124 Fixed NMEM system to return aligned blocks on the smallest boundaries
1125 that are suitably aligned for all possible types on the particular
1126 architecture YAZ is being built for.
1128 --- 2.0.30 2005/01/04
1130 Fixed numerious warnings that was issued with newer versions of GCC.
1132 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1133 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1136 Make YAZ Generic Frontend Server slightly faster.
1138 Enhance (and reduce) logging for Generic Frontend Server.
1140 Revert YAZ log system so that it flushes every write operation
1141 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1143 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1144 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1145 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1146 will effectively disable old definitions.
1148 --- 2.0.28 2004/11/09
1150 Added yaz_log_time_format which specifies log format using
1153 Added yaz_log_module_level which returns mask for a module. Value
1154 is non-zero mask a if module is enabled; zero if disabled.
1156 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1157 in include/yaz/cql.h.
1159 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1161 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1163 Fixed bug #172: RPM builds does not enable SSL.
1165 Doxyfile.in part of dist. Doxyfile generated by configure.
1167 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1168 are given and the corresponding component does not exist.
1170 Extend CCL documentation in YAZ reference. Describe r=r.
1172 --- 2.0.26 2004/10/01
1174 Fixed MARC->MARCXML conversion to properly deal with
1175 fields, subfields, indicators having non-ASCII characters.
1177 Fixed MARC->MARCXML conversion so that ASCII control characters
1178 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1181 Added YAZ GFS support for conversion from Z39.50 surrogate
1182 diagnostics to SRW surrogate diagnostics.
1184 Bug fix: YAZ GFS did not return schema in explainResponse.
1186 --- 2.0.25 2004/09/30
1188 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1189 now converts recordSchema to elementSetName as well as schema URI.
1191 Fixed bug in COMSTACK that prevented HTTP request packages from being
1194 --- 2.0.24 2004/09/29
1196 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1197 does not require white-space before and after the dash in a range, e.g.
1198 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1201 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1202 due to new GCC removing "redundant" code.
1204 Added yaz-client commands scanpos and scanstep that sets preferred
1205 position and step-size for scan.
1207 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1209 Added CCL utility ccl_qual_buf which parses one or more CCL
1210 spec lines in a buffer.
1212 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1213 of name and value - ignoring empty lines and comments.
1215 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1217 Added odr_get_element_path which returns current element path for an
1218 ODR handle. This utility is useful in error handling or user-defined
1221 Added ODR_PRINT utility odr_set_stream which is is a more generic
1222 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1223 to a write function and pointer to close function. The close function - if
1224 non-NULL - will be called during odr_destroy.
1226 Fixed bug in CCL parser where truncation char was not removed from
1227 right side when truncation=both was in effect.
1229 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1232 --- 2.0.23 2004/08/11
1234 Fix buffer overrun in CQL parser when dealing with proximity (%).
1236 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1237 to UTF-8/UCS conversion is now only based on codetables.xml.
1239 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1241 --- 2.0.22 2004/08/06
1243 Add support for more "commit changes" in ZOOM (uses Extended Services).
1245 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1248 Yet another small fix for configure of SSL.
1250 --- 2.0.21 2004/05/14
1252 Fix SSL libs for configure when --with-openssl=DIR is given.
1254 --- 2.0.20 2004/05/10
1256 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1258 SSL comstack now uses yaz.pem certificate file on server side
1259 by default. Certificate filename can be configured by calling
1260 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1262 Fix bug regarding multiple calls to ZOOM_connection_connect.
1264 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1266 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1267 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1269 ZOOM now allows inspection of X509 peer certificate for verification.
1270 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1272 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1273 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1274 as "modular" but it simplifies things.
1276 Added cs_get_peer_certificate to that returns peer X509 PEM.
1278 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1279 NULL if SSL is unavailable.
1281 Documentation about MARC decoding tools.
1283 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1285 --- 2.0.19 2004/03/30
1287 Rename CHANGELOG to NEWS to follow GNU style packing.
1289 Fix bug with missing initialization of member in init_diagnostics.
1290 This bug affects threaded version of GFS server.
1292 --- 2.0.18 2004/03/20
1294 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1297 Ensure zlib.dll is packed with Windows install.
1299 --- 2.0.17 2004/03/17
1301 Fix encoding of xsd:string to use text instead of CDATA.
1303 Fix endless loop in CQL parser with unbalanced ".
1305 Use a more compact way to store MARC-8 conversion tables.
1307 --- 2.0.16 2004/03/16 Debian only
1309 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1312 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1317 --- 2.0.15 2004/03/01
1319 Another fix for decoding of XML packed records.
1321 --- 2.0.14 2004/02/25
1323 Fixes for Chunked encoding. White space not ignored after length spec.
1325 Update NS and use default NS for SRW diagnostic elements.
1327 --- 2.0.13 2004/02/23
1329 Implement ZOOM_resultset_cache_reset which resets record cache.
1331 Implement ZOOM_resultset_sort which sorts a result set.
1333 Implement chunked HTTP transfer.
1335 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1337 --- 2.0.12 2004/02/16
1339 Added member 'schema' to bend_explain_rr structure so that backend
1340 can specify explain record identifier. Defaults to Zeerex 2.0.
1342 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1344 --- 2.0.11 2004/02/16
1346 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1349 Added init command for yaz-client which sends "extra" init request.
1351 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1352 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1354 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1356 Make ZOOM error code for "invalid query".
1358 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1360 --- 2.0.10 2004/02/05
1362 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1365 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1367 Added option -p <file> to make Generic Frontend Server to write PID file.
1369 Added option -D to put Generic Frontend Server in background on its own.
1371 Make ZOOM C recognize option "password". If unset, "pass" is used
1372 (for backwards compatibility).
1374 Fixed a bug in Generic Frontend Server that could make it crash if a
1375 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1378 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1379 Must be issued before open, in order to be in effect.
1381 --- 2.0.9-6 2004/01/12 Debian/Windows
1383 Make the SRU server more picky WRT unknown params, etc.
1385 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1387 New YAZ client command, options, that sets Z39.50 options.
1389 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1390 options from a string of tokens (one token for each option bit).
1392 Update SRW diagnostic code messages.
1394 --- 2.0.9-5 2004/01/07 Debian/Windows
1396 Handle user defined stylesheet for SRW/SRU.
1398 --- 2.0.9-4 2004/01/06 Debian/Windows
1400 Fix bug in decoding of Content-Length.
1402 --- 2.0.9-3 2004/01/06 Debian/Windows
1404 Fix a bug with decoding of XML packed records.
1406 --- 2.0.9-2 2004/01/05 Debian only
1408 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1410 Fix bug in SRW/SRU diagnostics decoding.
1412 --- 2.0.9 2004/01/05
1414 Fixed bug in Generic Frontend Server which could drop records exceeding
1415 preferred message size. Reported and fixed by Irina Dijour.
1417 Fixed calculation of package size for structured records in Generic
1418 Frontend Server. Reported and fixed by Irina Dijour.
1420 Fixed namespace for SRW/SRU diagnostics.
1422 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1424 --- 2.0.8 2003/12/22
1426 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1427 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1430 CQL changes to reflect recent changes to the specification:
1431 * Documentation talks about context sets instead of index sets.
1432 * Documentation talks about indexes instead of qualifiers.
1433 * The CQL-to-PQF transformer's configuration file now uses
1434 "index.set.name = <attributes>" instead of the old form
1435 "qualifier.set.name = <attributes>". (Both forms are still
1436 understood but the latter is deprecated.)
1437 * CQL terms with no explicit index specified are now interpreted as
1438 cql.serverChoice instead of srw.serverChoice (which of course
1439 behaves exactly the same.)
1441 --- 2.0.7 2003/12/16
1443 MARC conversion can now generate ISO2709 output in another
1444 character set. yaz-marcdump uses this facility if you invoke it
1447 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1448 functions from there can be used from C++.
1450 --- 2.0.6 2003/12/04
1452 Frontend server now transfers memory from decoded packages to stream
1455 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1456 references to show up.
1458 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1459 the ZOOM Abstract API. The older names for the same options are still
1460 also supported for the benefit of old applications.
1462 ZOOM-C supports "implementationId" and "implementationVersion" options
1463 to go along with "implementationName". These allow the user code to
1464 specify identification strings to be sent to servers.
1465 Add OID for the new ExtLite attribute set.
1467 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1468 as requested/supplid by Ere Maijala <ere@atp.fi>
1470 For generic frontend server, reverse the order of
1471 "toolkit-supplied / application-supplied" strings sent as implementationId,
1472 Name and Version. Also, remove the spaces around the slash. This brings
1473 the GFS in line with the behaviour of ZOOM-C on the client side.
1475 Add function ZOOM_scanset_display_term.
1477 yaz-client shows scan displayTerm if present.
1479 Utility yaz-iconv is now installed by default along with the man page
1482 Extend configure check for OpenSSL to use pkg-config where available (such
1485 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1486 server to specify uid/gid/mask for socket using the format
1487 unix:[user=uid,][group=gid,][umask=mask,]file=path
1488 If file= is omitted the existing format is assumed, e.g.
1490 in which case the mask is 0666 (rw for everybody).
1492 Major restructure of YAZ source. All source in libyaz is in src directory.
1493 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1494 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1496 Added man page for utility yaz-marcdump (used to be called marcdump).
1497 yaz-marcdump is installed by 'make install'.
1499 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1500 of incoming package failed.
1502 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1504 Change prototype of odr_perror: add const to message string.
1506 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1508 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1509 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1510 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1511 DNS lookup. There should not be any compatibility problems with this
1512 assuming that blocking=1 or 0 is used.
1514 Fix bad reference in UNIX comstack in function cs_addrstr.
1516 Fix for compilation on AIX.
1518 The generic front-end server (server/seshigh.c) now supports returning
1519 Init diagnostics to the client in User-information-field, in
1520 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1523 --- 2.0.4 2003/09/04
1525 Allow any CQL relation (not just all,any,exact,scr).
1527 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1528 that features the same UI.
1530 Implemented command update0 in YAZ client which is equivalent to
1531 update but uses old of Ext Update ASN.1.
1533 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1534 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1535 Previously no OID was used for this info.
1537 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1538 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1539 returns 'malformed search term' otherwise.
1541 SortResponse member resultCount now set to NULL in sort handler of
1544 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1547 Add three new utility functions for translating OIDs between various
1548 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1549 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1550 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1551 char *oid_to_dotstring(const int *oid, char *oidbuf);
1552 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1554 Reverted modifications for ES Update definition for z_IU0Update
1555 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1556 is back to YAZ 2.0.2.
1558 String value attributes for CCL parser.
1560 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1561 which their FirstSearch server returns in Init responses, sometimes
1562 carrying useful diagnostic information when Init fails. This has the
1563 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1564 "z39.50/oclcui.asn", where its definition is somewhat different from
1565 what OCLC document on their web-site, as required to interoperate with
1568 Support for anonymous authentication in yaz-client. Use the command
1571 * Fix the OID of the Index Data-local "admin" Extended Service from
1572 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1573 the 1000, which indicates a locally-defined OID, was a mistake.
1575 --- 2.0.3 2003/06/20
1577 Fix CCL directive @case handling so that it affects string match for
1578 both CCL keywords and qualifiers.
1580 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1581 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1582 Decoder has been updated with ASN.1 changes as listed in
1583 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1584 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1585 z_IUUpdate, remains unchanged.
1587 ZOOM_record_get may now return a record in a specific character set.
1588 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1589 "from" is the character set of record as returned by target. "to" is
1590 the character set to be returned. If omitted, "to" is UTF-8.
1592 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1594 New ODR utility, odr_getelement, which returns name of element for
1595 which encoding/decoding failed.
1597 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1598 in cases where a required element was omitted.
1600 Bug fix: some MARC8 sequences were not converted.
1602 New ZOOM option "step" which specifies number of records to be
1603 retrieved in one chunk. Used in conjunction with "start" and "count".
1605 SRW support for yaz-client. Use scheme http: to use it, e.g.
1608 yaz-client no longer does (un)intelligent character set conversions
1609 by default. Can be enabled with charset and marc_charset commands.
1611 xmalloc trace fix for 64-bit systems such as DEC alpha.
1613 Solaris 2.6 compile fix.
1615 New function, cql_strerror() translates SRW error codes, as returned
1616 by cql_transform_error(), into human-readable English strings. Used
1617 in yaz-client diagnostics when appropriate.
1619 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1620 converts it into a type-1 query which is sent to the server. This
1621 makes CQL available for use with all Z-servers, as opposed to the tiny
1622 minority that can handle CQL queries themselves.
1624 --- 2.0.2 2003/04/28
1626 New Debian package layout similar to the Redhat Package layout.
1628 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1629 and search result respectively.
1631 --- 2.0.1 2003/04/25
1633 Redhat package is now several packages: libyaz (runtime libraries),
1634 libyaz-devel (development and documentation, and yaz (utility programs).
1635 Package spec file by Morten Bogeskov.
1637 New member 'schema' in struct bend_fetch_rr which the name of requested
1638 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1639 handler MAY set this to reflect the schema of the returned record.
1641 New member 'display_term' in struct scan_entry. GFS now sets member entries
1642 and allocates scan entries to be filled by user scan handler. In previous
1643 version, entries member was allocated by the scan handler. That still works,
1644 but the GFS will ignore member display_term - assuming it was NOT set by
1645 the handler. The fact that the GFS now allocates the entries both allows
1646 for new members and makes a scan handler easier to write.
1648 Fix CQL lex buffer overflow.
1650 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1651 SRU default recordPacking is string.
1653 SRU protocol support for frontend server.
1655 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1657 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1659 Added scan for the ZOOM shell (zoomsh).
1663 * String Identifers for Schemas (Amendment 5).
1664 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1665 Old definition for schema
1666 Odr_oid *schema; /* OPT */
1671 Z_InternationalString *uri;
1672 #define Z_Schema_oid 1
1673 #define Z_Schema_uri 2
1676 * resultCount parameter to Sort Response (Amendment 1).
1677 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1679 Support for SRW 1.0 over HTTP. This is an optional feature and
1680 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1683 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1684 on the same port. SRW SearchRetrieveRequests are mapped
1685 to bend_init,bend_search,bend_fetch,bend_close.
1687 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1689 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1690 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1692 ZOOM connections are SRW based if schem http is used for hostname
1693 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1694 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1696 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1697 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1698 distance=n, order=true/false, relation=le, prox unit=word. If
1699 n is omitted, distance 1 is used.
1701 Fixed problem with C compiler include path in wrong order.
1703 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1704 on Solaris. Patch from Ko van der Sloot.
1706 New MARC decode API. All new functions operate on a yaz_marc_t
1707 handle. The most important new functions are: yaz_marc_create,
1708 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1709 decode and destroy respectively. Decoder can produce formats
1710 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1711 include/yaz/marcdisp.h.
1713 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1714 to UTF-8, UCS-32, wchar_t or Latin-1.
1716 * Prototypes for yaz_iconv_-functions moved to separate header
1717 include/yaz/yaz-iconv.h.
1719 Make a few private functions 'static' in unix.c. This prevents
1720 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1722 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1723 are set when Init Response is received.
1725 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1726 but returns diagnostic set as well.
1728 New function yaz_strerror which is a portable wrapper for
1729 strerror/strerror_r/GetLastMessage.
1731 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1732 is returned for MARC. If type is "oai", then OAI MARC is returned.
1734 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1737 --- 1.9.2 2002/11/26
1739 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1741 Fix bad race conditions on SIGTERM and terminate gracefully in
1744 Move retrieval (data1) module to Zebra since nobody seems to be
1747 Add GRS-1 render for ZOOM using same format as yaz-client.
1749 --- 1.9.1 2002/10/05
1751 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1753 Fix broken ESpec handling in data1 module.
1755 SGML reader parses comments and makes them part of the data1 tree.
1757 Added several type casts so that YAZ compiles as C++ code.
1759 ZOOM didn't handle PDU encoding failures properly.
1761 Added more Bib-1 diagnostics (approved extensions).
1763 GNU configure: better check for iconv.
1765 More portable use of accept, getpeername. Check for socklen_t. Use
1766 int/size_t if socklen_t is not defined.
1770 PQF parser rejects bad queries - including those with extra
1771 characters in them. PQF parser used to silently ignore that.
1772 Cleaner API for PQF added, which allows you to get detailed
1773 error information for bad queries (see yaz/pquery.h).
1775 Fixed bug in ZOOM_record_get for type "database".
1777 Implemented mini iconv library supporting conversions between
1778 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1780 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1782 --- 1.8.9 2002/08/20
1784 Fixed ZOOM C record cache so that preferredRecordSyntax and
1785 elementSetName is used to check for already fetched records.
1787 --- 1.8.8 2002/08/02
1789 Added three members in bend_initrequest structure to facilitate
1790 character set negotiation.
1792 Fixed a bug in frontend server that could cause indefinite
1793 loops under rare conditions.
1795 Revised character set utilities (charneg.h) so that encoding
1796 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1798 For PQF, directive @term <type> sets term type for Scan/Search.
1799 Here <type> is general, string, numeric, null. The term type
1800 is inherited - just like @attr.
1802 New call odr_set_charset that sets character set conversion for
1803 international-strings on a ODR stream. Prototype is:
1804 int odr_set_charset(ODR o, const char *to, const char *from);
1805 The InternationalString is still represented as C string in YAZ
1806 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1807 won't). On the protocol level, you can use any encoding.
1809 Support for UNIX sockets in ZOOM.
1811 Solaris recv sometimes returns errno == ENOENT. It is treated as
1812 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1814 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1815 both client and server. Code by Morten Bogeskov.
1817 --- 1.8.7 2002/05/22
1819 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1820 that they can be used directly from Visual Basic. You must recompile
1821 your windows APP if you're using ZOOM.
1823 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1824 Commands "lang" and "charset" sets language and character set respectively.
1825 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1826 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1828 Attributes from multiple CCL fields may be OR'ed rather than merged
1829 using directive "@field or". Fields are still merged by default -
1830 equivalent to "@field merge".
1832 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1835 Fixed bug in zget for parameter ExtendedServicesResponse.
1839 --- 1.8.6 2002/03/25
1841 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1843 Client displays USR.1:SearchResult-1 (hits per term).
1845 Additional Search Info for search in Generic Frontend Server.
1847 Fixed CCL parsing of "field=s".
1849 WIN32 installer - using the excellent NSIS software from nullsoft.
1851 Fixed CCL parsing of "field = - <number>".
1853 Added function yaz_marc_decode that decodes MARC for line mode
1854 display or XML (similar to that used by JZKit).
1856 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1857 Z39.50. But ISO/ILL was, however.
1859 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1860 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1865 --- 1.8.5 2002/02/03
1867 New YAZ client features: Command completion and new commands:
1868 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1869 Code provided by Jacob Poulsen.
1871 New call oid_trav, that visits all registered OIDs via callback.
1873 Function ZOOM_record_get now returns const char pointer rather than
1874 void pointer. It saves a lot of type casts.
1876 For YAZ client, command "auth" now allows you to set authentication
1877 in IdPass style. It is enabled when three tokens are given - order
1878 is user, group and password.
1880 Fix memory leaks in MARC record handling for ZOOM.
1882 New option for YAZ client, -k <kilobytes> that sets
1883 maximum record size. Similar to -k option for generic frontend
1884 server and yaz-ztest.
1886 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1888 Prefix query parser reports "fail" when bad attribute set is given.
1890 Fix in MARC decoder. Proximity logging. Fix for attribute set
1891 in scan handler for server. Patches by Shigeru Ishida.
1893 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1896 Configure option --with-openssl=<dir> now works when a directory is
1897 specified. Patch provided by Morten Bogeskov.
1899 New option for YAZ client, -u <auth>, that sets authentication.
1901 ZOOM fix: error information was sometimes "missing", since error
1902 was cleared/reset too when it shouldn't.
1904 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1906 --- 1.8.4 2002/01/04
1908 Scan for ZOOM API. New object ZOOM_scanset. New functions
1909 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1910 ZOOM_scanset_destroy.
1912 New ZOOM function, ZOOM_connection_last_event, that returns type
1913 of last event (such as "receive data", "send data", "apdu received",
1916 New ZOOM option, schema, that specifies schema for retrieval.
1918 New CCL feature. Qualifiers can be aliases for one or more
1919 other qualifiers (if more than one is given, OR is used).
1921 ZOOM uses named result sets if target supports it.
1923 Two new YAZ client commands: . (dot, which sources a script of YAZ
1924 client commands), and ! (to execute shell command.). Implemented
1927 Working on Debian packages.
1929 --- 1.8.3 2001/11/19
1931 YAZ client enables named result sets only if target supports it.
1933 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1935 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1936 with key="host" to get same result.
1938 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1939 Function Z3950_resultset_record(s) returns references to records
1940 "owned" by resultset. To become owner use Z3950_record_clone.
1942 Function z_ext_record handles Extended Services. Thanks to
1945 --- 1.8.2 2001/11/12
1947 CCL Parser fix: ignore token comma when dealing with and-lists.
1949 Documentation updates for COMSTACK.
1951 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1952 Changed prototype Z3950_records. For some functions, int parameters
1953 were changed to size_t.
1955 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1958 New MARC decode/display function, marc_display_exl, which properly rejects
1959 non-ISO2709 records. YAZ client uses it.
1961 --- 1.8.1 2001/10/29
1963 Fix bug: local attribute set wasn't set correctly in PQF strings.
1967 * Old Z39.50 codecs no longer supported.
1969 Added ZOOM C binding. See http://zoom.z3950.org/
1971 Renamed states for COMSTACKs to avoid confusion with events.
1973 Implemented cs_look and proper cs_rcvconnect.
1975 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1977 Configure detects POSIX threads on OpenBSD.
1979 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1980 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1982 When error is returned from present handler, non-surrogate diagnostic
1983 is returned in present response (and fetch handler is no longer called).
1985 * Minor adjustments to pquery parser (PQF). Token characters may be
1986 escaped by using backslash (C-style).
1988 PQF parser allows string attribute values to be specified. For @attr,
1989 non-numeric characters after the equal-sign are treated as strings
1990 (e.g. @attr 9=title).
1992 CCL trunction character may be defined (@truncation in file)
1994 * function zget_ExtendedServicesRequest sets waitAction to
1995 waitIfPossible (was wait).
1997 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2000 CCL operator names may be set in field definition files (CCL_bibset).
2001 See ccl/bib1 for an example.
2003 Fixes in ASN.1 compiler for C++ compatibility.
2005 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2006 and "op_or" to avoid conflict with C++.
2008 Fixed problem with GNU readline detection on Redhat 7.0.
2010 Added step-size for Scan backend handler.
2012 Fixed bug that made the frontend server crash when no attribute
2013 set was specified for scan.
2015 Front-end server automatically switches to original working directory
2016 when installed as an NT service. Previously -w had to be specified to
2019 Added extended attributes for retrieval module (data1), so that data1
2020 records carry d1_readXML/SGML attributes. d1_read also supports
2021 null-data rules ( <tag/>)
2023 On UNIX when POSIX threads are available, a separate library libyazthread
2024 is created. Programmers should link with that library and the yaz library
2025 when using threads. The reason for the split was that some applications
2026 on Linux, such as Apache, doesn't work well when using shared objects that
2029 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2030 (or any frontend server) in SSL mode by specifying ssl: followed by
2031 address. Only tested on UNIX.
2033 Added feature for CCL module. Virtual structure s=al or s=ol generates
2034 and-list and or-list respectively instead of phrase search.
2038 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2039 log_mask_str. This was done to avoid name conflicts with other libraries
2040 (such as other PHP extensions).
2042 Added raw OID member for preferred record syntax (request_format_raw)
2043 and returned record syntax (output_format_raw) for backend fetch method.
2045 Config file yaz-config now accepts options so that it returns specific
2046 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2048 Shared library support for UNIX using GNU libtool.
2050 * Modified backend interface. Request/Response struct's replaced by
2051 one read/write C struct. For example bend_fetchrequest and
2052 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2053 Every handler - even search has to be registered in bend_init
2054 handler. This means that the YAZ library no longer refers to
2055 external functions and it makes it possible to make the whole
2056 thing a single DLL/SO.
2058 Added Segment handler for backend server.
2060 Added Zmbol/Zebra administrative functions to YAZ client.
2062 Threaded frontend server on UNIX (when POSIX Threads are available).
2063 Starting the server with option -T enables multi-threading.
2067 Added configure option --enable-comp/disable-comp to control use
2068 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2069 located in sub directory asn.
2071 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2072 in ${exec_prefix}/bin along with the other programs yaz-client and
2075 GNU automake used to maintain makefiles.
2077 Added several OID's.
2079 Changed retrieval module so that we can load records with no abstract
2080 syntax defined. Tagpaths in these records are fully composed of string
2083 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2087 On UNIX, the generated makefile now supports a proper 'make install'.
2088 The prefix can be set via GNU configure to set the install location
2089 (default is /usr/local).
2091 * YAZ programs client and ztest were renamed to yaz-client and
2092 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2093 locations, such as /usr/bin,/usr/local/bin,etc.
2095 * YAZ Header files were moved from include to include/yaz. YAZ Header
2096 files are referred to as include <yaz/log.h> rather than <log.h>.
2097 The YAZ include path (-I ..) is therefore the same as before. Programmers
2098 should update their #include statements or use -Ipath/include/yaz
2099 instead. The main motivation for doing this change is that YAZ header files
2100 can be installed in "standard" locations /usr/include,/usr/local/include
2101 without introducing conflicts, since ALL YAZ header files are stored
2102 in subdirectory yaz (under /usr/include for example).
2104 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2105 rather than project/workspace files. We switched because project files
2106 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2109 Changed name of logging function, logf, to yaz_log, to prevent name
2110 clash with some math-log functions. The YAZ header log.h defines logf
2111 to yaz_log (#define) so there should be no incompatibilities by this
2114 Added bend_start/bend_stop handlers for server. These handler are
2115 called on start/stop of server. For windows they are called whenever
2116 a service is started/stopped.
2118 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2119 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2120 in util/yc.tcl. The auto-generated C code structures are, in a few
2121 cases, incompatible with the old decoders. There are differences in the
2122 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2123 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2124 The preprocessor variable ASN_COMPILED is defined when the compiled
2125 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2126 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2127 wish to use the old encoders/decoders you can specify --disable-yc
2130 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2131 version so that it supports both new - and old version of DB Update
2133 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2134 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2135 change. The name parameter can be set to 0 in which no name is specified
2136 for the construction. The macros odr_implicit and odr_explicit sets name
2137 parameter to zero for the construction involved. New macros
2138 odr_implicit_tag and odr_explicit_tag are similar to the others,
2139 except that a name parameter is added. For programmers' that don't use
2140 ODR they probably only need to change the call to z_APDU and z_External.
2142 Added access control facility by interfacing the TCP wrapper library.
2143 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2144 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2145 name of the daemon and enables the access control as specified in
2146 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2148 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2149 den Dool <H.M.vdnDool@kub.nl>.
2151 Added reference ID parameter to most functions in server API - refer
2152 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2154 Changed name of ccl library to libccl.a (was ccl.a).
2156 Fixed bug in decoder for Explain (Category TargetInfo).
2158 Added support for GNU readline in client. Thanks to Jacob Poulsen
2159 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2161 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2162 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2163 IMPLEMENTATION! This change was made to the development version before
2164 the ZIG decided to retract the amendment. If any users MUST be
2165 compatible with the original Update definition, PLEASE CONTACT US, and
2166 we will include a separate definition corresponding to the old Update
2167 ES. Note that because of the change to the ASN.1 of the
2168 TaskPackageRecordStructure we cannot define a single structure that
2169 will support both versions.
2171 * Added const modifier to buffer parameter for some ODR/BER encoding
2172 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2173 completeWAIS, odr_dumpBER.
2175 Fixed bug in client.c which caused a crash when a scanResponse didn't
2176 contain positionOfTerm.
2178 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2179 * will cause an error in a client if a non-YAZ target sends both a
2180 * list of Scan entries and non-surrogate diagnostics.
2182 Retrieval module enhancements. Tag sets may be typed in the reference
2183 to it. From the .abs-file the "tagset" directive takes a third optional
2184 integer type for the tag set referenced. From a .tag-file the "include"
2185 directive takes a third optional type as well. The old "type" directive
2186 in the tag set itself is still recognized but acts as the default type
2189 Backend interface change. Individual Scan terms returned from bend_scan
2190 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2191 in include/backend.h.
2193 Retrieval module enhancements. Multiple tag sets and attribute sets may
2194 be specified in abstract syntax specs. Revised the error/warning for
2195 logging messages reported by the retrieval module when reading the
2198 Object Identifier system (oid_..) changed. The API is backwards
2199 compatible but the oid-routines now allocates new OID's when needed.
2200 Raw OID's may be specified in oid_getvalbyname.
2202 YAZ now uses GNU configure to generate Makefile(s).
2204 * Minor changes in some of the member names of DeleteResultSetRequest and
2205 DeleteResultSetResponse. See include/proto.h.
2207 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2208 and added member 'languages' in TargetInfo (which was missing).
2210 Changed the way attribute sets are handled in the retrieval
2211 module. These are now cached, just like the abstract syntaxes
2214 Changed YAZ so that it links with compiled ASN.1.
2216 Added Explain-schema definitions and mapping routines. The following
2217 Explain categories have been implemented: AttributeDetails,
2218 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2220 Fixed minor bug in Windows version of Server Library.
2222 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2224 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2226 Added EXTERNAL: UNIverse Resource Report (non-standard).
2228 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2229 ENUMERATED and SET OF.
2231 * Added 'const' to some of the char pointer arguments for the
2232 functions, data1_read_node, data1_getelementbytagname,
2233 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2236 Fixed bug in data1_insert_taggeddata - the last_child member of
2237 parent wasn't initialised.
2239 * Changed data1_read_record and data1_read_node so that the supplied
2240 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2241 doesn't refer to any parts of the "SGML"-buffer.
2243 Fixed bug in server library (Windows version of statserv_remove).
2245 * Changed code so that it compiles as C++. The type definition
2246 of Odr_fun which is a member of Odr_arm was changed. The result is,
2247 that an explicit typecast is needed for the fun pointer when
2248 using Odr_arm - as in:
2249 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2251 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2253 Implemented the new structured date and time definition as approved
2254 by the ZIG. Added schemaId element to the specificTag in Espec-1
2255 (also approved at the last ZIG). Thanks to RVDM.
2257 Added some Object identifiers (RVDM).
2259 Changed the Update Extended Service (RVDM).
2261 Added command "refid" to client which specifies referenceId for
2262 the following requests.
2264 Implemented extended service handling for server. See ztest.c
2265 for an example as well as backend.h. New handlers are registerd
2266 in the Init handler.
2268 * Changed interface for sort in server.
2270 Added new members to statserv_options_block. It allows a server
2271 to read options from another source than just the command line. Thanks
2272 to Charles Woodfield.
2274 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2275 renamed to zboolean. Some C++ compilers complained about the name.
2277 Minor changes to gils.abs. Added index 's' (sort) on title
2278 and date/time-last-modified.
2280 --- 1.4pl2 1998/1/30
2282 Fixed bug in server library regarding inetd mode (-i). This bug
2283 was introduced by release 1.4.
2285 --- 1.4pl1 1998/1/29
2287 Added sort facility in client and backend server interface.
2289 Fixed problem with dependencies in Makefile(s).
2291 Fixed bugs for encoders/decoders of extended services and
2294 Implemented sub-tree feature for schemas. Sub-trees are
2295 referenced in *.abs-files. See explain.abs for an example
2296 of the use of this feature.
2298 Modified bib1.att; local attributes for ANY didn't include
2299 ANY itself (only affects use of the retrieval module).
2301 Fixed bug in plain SGML reader in function data1_read_node:
2302 tags with prefix "var" was incorrectly interpreted as variants.
2304 Added feature "sub-schemas" to enable references to - and definitions
2305 of - group of elements.
2307 * Removed member parent from type data1_element (in data1.h).
2309 Implemented function odr_nullval() that returns the value of
2312 * Removed member num_children from data1_node (in data1.h).
2314 Made NT service interface part of the server library. The
2315 function statserv_main uses the NT service when required and
2316 calls the statserv_start / statserv_close routines.
2318 Routine zget_SearchRequest and zget_PresentRequest fills
2319 resultSetName/Id member with "default" instead of "Default".
2321 Fixed memory leak in server. Request queue member wasn't freed.
2323 Fixed nmem_exit so that memory is freed.
2327 Revised the CCL parser utility to be thread safe.
2329 Added function, oid_ent_to_oid, to replace the function
2330 oid_getoidbyent, which is not thread safe.
2332 * Added nmem_init and nmem_exit to initialize and release
2333 NMEM resources. Function nmem_init should be called once in the
2334 initial thread before NMEM/ODR is used. statserv.c and client.c
2335 have been changed accordingly. The change was necessary to make
2336 NMEM thread safe. The NMEM memory pool is shared amongst threads
2337 in a process. Unix-based applications will still work fine without
2340 Added NT Services interface for the the Z39.50 (statserv) Server.
2341 Refer to the ztest.c source on the usage.
2343 Windows 95/NT port using MSVC5.0. Project files are included in the
2346 * Defined new 'global' handle for the retrieval (data1) system. The
2347 new handled, data1_handle, describes the state of the data1 system.
2348 This handle is passed as first argument to virtually all
2349 data1 related routines. The functions data1_create and data1_destroy
2350 creates and destroys a data1 handle respectively.
2352 Added ODR encode stream member to all backend request structures
2353 init, search, scan etc. This stream should be used to allocate all
2354 memory used for the response when thread safe operation is needed.
2356 Changed the comstack utility, cs_addstr, to be thread safe. The
2357 returned hostname string returned by the function is now part the
2360 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2361 function. The cs_straddr takes a COMSTACK handle as argument, so this
2362 function must be used after cs_create and before bind/connect.
2363 This function is thread safe.
2365 Moved test server to 'ztest' directory - generic server code still
2366 in 'server' directory.
2368 Made prefix query (pquery.c) utility thread safe.
2370 Added new function modifier YAZ_EXPORT to 'export' public DLL
2371 functions when using windows (see include/yconfig.h).
2373 Added definitions to the OID database (util/oid.c) (RVDM).
2375 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2377 Added call to ccl_rpn_delete in client program.
2379 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2380 release of RPN structure.
2382 Added support for C++, headers uses extern "C" for public definitions.
2383 With input from RVDM.
2385 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2386 Thanks to Ronald van der Meer (RVDM).
2388 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2390 Added support for private extensions to the OID database
2391 (oid_setprivateoids()). Thanks to RVDM.
2393 Added optional, physical ANY (key replication)
2395 Fixed null-reference problem in GRS-1 output filter.
2397 Proximity operator added to Prefix Query Format (PQF).
2399 In test client command "base" accepts multiple databases.
2401 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2405 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2407 Smallish bug-fixes in the new encoders/decoders (explain).
2409 Bug fixed in DeleteRequest.
2411 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2413 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2415 Added SOIF syntax (using private OID for now) to retrieval module and client.
2417 Added Update extended service.
2419 Added SearchResult-1 additional info structure.
2421 Added optional CCL (ISO8777) interpreter as separate module. Available
2424 --- 1.2 1996/6/10 (1st anniversary release)
2426 Added Summary record syntax. Lightly tested.
2428 Added OPAC record syntax. Untested.
2430 Added ResourceReport service encoders/decoders. Untested.
2432 Fixed bug in z_Unit - wrong tagging on unitSystem.
2434 Fixed bug in the DiagRecs decoder.
2436 Added options for max PDU size and session timeout to frontend-server.
2438 Added documentation of query-language parsers and other supporting utilities.
2440 [frontend-server] Added Attribute set to the bend_scanrequest API.
2442 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2443 surrogate diagnostics were generated.
2445 [retrieval] Allow multiple local values for attribute.
2447 [retrieval] Allow multiple attributes per element in .abs files. index type.
2449 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2451 --- 1.1pl2 1996/4/10
2453 Minor changes, mostly specific to Zebra's requirements (retrieval)
2457 Repaired bug in frontend server when running multiple listening
2458 endpoints in dynamic mode.
2460 z_External() now won't break if a known, ASN.1 value comes encapsulated
2461 in an octet-string. The value will pass through unmodified in an Odr_oct.
2463 Added a bit of code to the demo client to decode & display
2464 ASN.1-structured records represented in the octet-aligned branch of
2465 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2467 Added z_ext_getentbyref() to the ASN module. Doc updated.
2469 * Completed the SCAN definition in the ASN module. This may break SCAN
2470 code based on older YAZ-versions at compile-time. The fix is easy -
2473 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2474 under the SCAN definition. Remember to initialize this, server-people.
2476 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2477 that this does not extend to ODR and ASN.
2479 Comstack allows insertion of established socket (primarily for
2480 inetd-operation of servers). Doc updated.
2482 Front-end server can now start from the inetd in TCP mode. Doc
2485 --- 1.0pl4 1996/1/24
2489 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2490 the rank and record number.
2492 Adjustments to the frontend server.
2494 Fixed diagnostic BER dumper. It ignored the file argument.
2498 Various changes to retrieval module.
2500 Changed the union discriminators of the protocol files from enums to
2501 ints paired with #defines.
2503 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2506 *Changed operator in the RPN structure to 'roperator', again to avoid a
2509 Fixed problems in Explain decoders/encoders.
2511 --- 1.0pl2 1995/12/6
2513 Memory bug in log module fixed.
2515 --- 1.0pl1 1995/12/5
2517 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2519 Bug in Explain DatabaseInfo module fixed.
2521 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2525 The shift to v1.0 signals that we now consider the *core* functionality
2526 of YAZ reasonably stable (the core being more or less equivalent to
2527 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2528 tested (Explain not at all - though that will happen soonish).
2530 Minor changes to code to support Windows port.
2532 Various minor changes after we're getting to use GRS-1 & co. more.
2534 Added Espec-1 format.
2536 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2537 of the protocol and it cannot be selected when encoding (maps into 'string'
2538 when decoding). Needed to talk to some servers.
2540 Demo client can request simple element set names.
2542 Added Diagnostic Format encoders/decoders.
2544 Added simple Close handling to frontend server (no hooks for resource
2545 reporting yet), and demonstration client.
2547 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2549 --- 1.0b3 1995/08/24
2551 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2552 handled incorrectly when records were requested in the searchResponse. This
2553 will only affect you if you use the frontend-server.
2555 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2556 Test-client will ask for and print GRS1. Ztest will return dummy records
2559 Added Explain encoders/decoders to the service-level API. Untested.
2561 Added Extended Services: Item Order encoders and decoders to the Service-
2562 level API. Untested. We could use a recent copy of the pertinent bits
2563 of the ILL protocol to add those bits.
2565 Added diagnostic format 1 encoders/decoders to the service-level API.
2568 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2569 odr_cons.c, which causes a more correct output.
2571 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2572 was always set to 0 when no records were requested in the searchRequest.
2574 * Added better external-handling. This shouldn't harm old code that
2575 *encodes* externals. It can break code that looks for a
2576 'single-ASN1-type' representation, since those types that are known
2577 are now decoded immediately. Look at the SUTRS sample code in
2578 seshigh.c and client.c. Documentation updated.
2580 Handling of structured records in bend_fetchresponse. Length -1 marks
2581 structured record, type is deduced from format field.
2583 --- 1.0b2 1995/06/27
2584 Fairly quick maintenance release to add SUTRS support.
2586 Fixed handling of SUTRS records in the demonstration client.
2588 * Added format field to the bend_fetchrequest and bend_fetchresponce
2589 structures of the backend API (frontend server). When the record is
2590 returned, the value of the format field is mapped to an OID. The
2591 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2592 of the record. The special value VAL_NONE in the bend_request means
2593 that no specific format was requested by the client. Documentation
2594 updated accordingly. Test server (ztest) will return a fixed dummy
2595 SUTRS record if your client requests SUTRS.
2597 Documentation updated accordingly.
2599 You can now set external libraries and RANLIB support in the top-level
2603 First public release.
