1 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
2 only the bibliographic record was rendered. For type=opac, an OPAC
3 record is only returned if it is present.
5 iconv: small fix for encoding of advancegreek.
7 yaz-client: avoid double display of SRU/SRW records (bug #2798).
9 yaz-client: option auto_reconnect=on really reconnects.
11 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
13 server: avoid null ptr ref for for yaz_poll errors.
15 build: fix RPM build for RHEL 5.3.
17 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
21 Fixed bug #2709: TCP connect returns Invalid argument.
23 Fixed compilation for mingw.
25 Honor charset for raw records (ZOOM_record_get).
27 Fixed use of errno for threaded mode that was seen on Solaris 10.
29 Fixed argument passing with blanks in value for Windows Service.
31 Disable YAZ' own log rotate by default (no 1 GB limit).
32 The variable l_max_size which specifies the log file limit is set to 0
33 (DISABLED): This is due to the fact that YAZ is most often deployed using
34 logrotate. Also YAZ can not perform log rotate because of unsufficient
39 List supported encodings in man page for yaz-iconv.
41 Fixed missing SSL libs for --libs output
43 Re-established OID record syntax application-xml. Nobody should use it
44 but we don't want to change soname because of this symbol being absent.
48 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
50 Added member named_result_sets for init handler struct for the GFS. This
51 allows a server to disable named result sets.
53 Removed OID record syntax application-xml.
55 Added support for rule-based transliterator for ICU wrapper of YAZ.
57 Fixed bug #1902: yaz-icu XML output.
59 Make YAZ checks Emacs friendly.
61 BITSTRING value shows value. Bug #2346.
63 ISO2709 decoding: skip control characters from indicator data.
65 Omit sort key by default in yaz-icu's output.
67 Allow combined single char options (again) for YAZ' options function.
69 Utility yaz-marcdump got option to display YAZ version (-V).
71 Allow YAZ to use ICU 3.4.
73 Added new ICU test case which illustrates removal of diacritics.
77 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
81 For configure, using option --without-xml2 also disables Libxslt/Libexslt
84 Fixed bug #2352: yaz-marcdump crashes for certain record.
86 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
88 Added support for Danmarc2 to UTF-8 conversion.
90 Added support for ISO5426 to UTF-8 conversion.
92 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
93 implementation version.
95 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
99 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
100 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
102 ZOOM C now interprets databaseName option for ZOOM connection as path
105 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
107 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
109 Dummy Libxml2 types no longer defined in headers of YAZ'.
111 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
114 --- 3.0.36 2008/09/26
116 Various ODR chapter fixes.
118 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
120 Added missing source for Windows compilation, mutex.c.
122 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
124 For SRU connections in ZOOM all records up to "count" are now fetched.
126 Fixed crash in generic frontend server (and yaz-ztest) which occurred
127 in Windows due to bad error handling for Libxml2.
129 Added facility for sending arbitrary records (ASN.1 any) using
130 ZOOM C's Extended service update. Patch by Sam Reynolds.
132 New options for ZOOM C's connection, logapdu which makes ZOOM log
135 --- 3.0.34 2008/06/18
137 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
139 --- 3.0.32 2008/06/12
141 Fixed memory violation that could occur when decoding UTF-8. This bug
142 was only present in 3.0.30 of YAZ.
144 --- 3.0.30 2008/06/06
146 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
147 GNU TLS is used by default (if found).
149 yaz-ztest returns OPAC records if a client asks for OPAC.
151 Improved speed of MARC-8 encoding.
153 Added support for lossy and loss-less MARC-8 encoding.
155 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
157 Added new Windows Service wrapper (sc).
159 yaz-client's itemorder command may now send a file.
161 Fixed yaz-marcdump to allow the use of NS prefix for record element.
163 Added new function yaz_log_xml_errors.
165 Allow (but warn) unknown XML attributes in MARCXML parsing.
167 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
169 The UTF-8 to MARC-8 conversion now uses a different set of characters
170 for Greek symbols. Bug #2120.
172 --- 3.0.26 2008/02/21
174 Added yaz_daemon (daemon.h).
176 Fixed bug #2068: pkg-config trouble
178 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
180 --- 3.0.24 2008/01/28
182 Document --with-xml2 option.
184 Added OPAC XML XSD (etc/opacxml.xsd).
186 Allow glob mask for name attribute in retrieval element for the
187 generic frontend server's retrieval facility.
189 Changed yaz_poll_poll to return yaz_poll_except for all returned events
190 except POLLIN/POLLOUT.
192 Fixed error handling in cs_listen. Bug #2037.
194 --- 3.0.22 2008/01/20
196 Fixed version in yaz/yaz-version.h.
198 Fixed bug #2027: Crash when closing connection.
200 Changed configure so that ICU support is only enabled if only ICU
201 and Libxml2 is available (because the ICU chain is XML based).
203 --- 3.0.20 2008/01/15
205 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
206 is built. Only this DLL depends on the ICU runtime.
208 yaz-ziffy is no longer part of YAZ. It is distributed separately by
209 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
211 Changed license of CCL module to 'Revised BSD'. After consultation with
212 remaining members of the original EUROPAGATE consortium, we are re-issuing
213 the CCL module without a separate license. The software was developed by
214 Index Data as part of a research project. The special license was included
215 to help feed usage information back to the project consortium to support
216 project evaluation. At this time, the project consortium has long-since
217 disbanded, and the majority of the original principals have retired. At the
218 same time, we have significantly modified the software during the following
219 years, to the point where very practically no original code remains. To
220 simplify re-use of the software, we have contacted those members of the
221 consortium who could be reached, and agreed to re-issue the module as a
222 proper part of the YAZ package.
224 Tcl scripts uses /usr/bin/tclsh as preferred shell.
226 CQL closer to being version 1.2 compliant. CQL also allows free-form
227 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
230 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
231 bug could make Extended services handling crash in the ZOOM layer. This
232 bug was only present in YAZ 3.0.18.
234 --- 3.0.18 2007/12/19
236 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
239 yaz-marcdump reads and writes collection wrapped records.
241 Handle OPAC for record conversion module.
243 Fixes for ICU wrapper.
245 Allow ICU libs to be controlled with --with-icu .
247 --- 3.0.16 2007/11/12
249 Added yaz_poll which is a wrapper for select/poll. When poll is available
250 and non-buggy, it is used, by yaz_poll . This allows more than 1024
251 sockets to be in use.
253 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
254 functionality through an XML based configuration (ICU chain). This system
255 is useful for search facilities such as Pazpar2 and Zebra that needs to
256 perform tokenization of indexed material. The ICU code in a separate
257 library libyaz3_icu.a.
259 Added HTTP tunnel facility for COMSTACK, bug #1752.
260 This is a facility that allows a Web proxy, such as squid, to tunnel
261 Z39.50 traffic. This facility is "transparent" to must applications
262 using YAZ. It's enabled by using pseudo transport connect: followed by
263 the proxy address, followed by command, then follwed by he regular
264 "virtual" addresss. For example,
265 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
267 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
269 --- 3.0.14 2007/09/21
271 Fixed bad memory reference in ZOOM_record - cuased by member not being
272 initialized. This was a problem only in YAZ 3.0.12.
274 Fixed bug in conversion from MARC to XML: Non-XML characters in control
275 fields were not removed.
277 Changed the way C code is generated from codetables.xml. Made a MARC-8
278 conversion trie for each characterSet section rather than codeTable.
279 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
280 of codetables.xml from Larry Dixson, LOC. Bug #1464.
282 --- 3.0.12 2007/09/12
284 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
285 from ZOOM_record_error).
287 ZOOM C function ZOOM_record_get returns record schema for type="schema".
289 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
291 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
293 Better SRW-to-Bib-1 diagnostic mapping.
295 ZOOM C and yaz-client announces SRU version 1.2 by default.
297 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
300 Fixed in yaz_sru_decode to allow other version than 1.1.
302 --- 3.0.10 2007/08/22
304 Added support for SRU scan for ZOOM.
306 Added support for the use of the older versions or Extended Service
307 Update in ZOOM. To faciliate this, an option "updateVersion" may be
308 set to the version , 1=first, 2=second, 3=third. The third version is
309 what ZOOM C has used so far. And that, obviously, is the default.
311 Added support for CCL queries in Z39.50 queries sent to the GFS (and
312 therefore in Zebra and in SimpleServer-based applications). The new
313 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
314 qualifier file used to transform incoming CCL queries into Type-1 RPN,
315 which is passed into the back-end search callback function.
317 Added support for HTTP Basic authentication in clients: the SRU/W
318 codec encodes the username/password elements of the PDU structure
319 appropriately, and these may be set using the "user" and "password"
320 options in ZOOM-C applications (the same options that are used for
321 Z39.50 authentication).
325 Fixed bug #1208: SSL appears to be broken in ZOOM.
327 Fixed bug #1206: Libxml2 include path weirdness.
329 Added oid_name_to_dotstring.
331 Allow elementSetName to be specified for ZOOM C record update.
333 Allow waitAction to be specified for ZOOM C based for Extended Services.
335 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
336 syntax OID. Bug introduced in YAZ 3 series.
338 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
342 Fixed bug #1157: yaz-client does not read .yazclientrc from current
343 directory. yaz-client now reads commands from file given by option -f
344 if specified; then tries to read .yazclientrc in current directory.
345 Failing that, it reads .yazclientrc from user's home directory.
347 Added support for correlationInfo Note and ID for Record Update via
350 Added yaz-client command querycharset which specifies character set for
351 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
352 (termListAndStartPoint).
354 Charset ISO5428:1984 is an alias for ISO5428-1984.
356 Implemented a way to perform scan in a result set using Z39.50. This
357 is achieved by attaching the result set name in the characterInfo
358 (type InternationalString) of OtherInformation in the Scan Request PDU.
359 The result set is identified in the otherinformation by the new OID:
360 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
361 This allows for scan in result set and faceted search . Zebra did some
362 of this in the APT term using attribute type 8 and value being result
363 set. Using the OtherInformation approach for this is cleaner and easier
364 to work with in proxies and the like. This facility can be used in
365 yaz-client using new command setscan which takes a result set as first
366 argument, start position (APT) as second.
368 Changed decoding of SRU XML packed records to deal with servers that
369 have recordData with XML data with multiple root nodes. Also make
370 comparison for recordPacking case insensitive. Again, one server
371 returns "XML" where others return "xml".
373 For SRU responses allow Content-Type application/xml as well as text/xml.
377 Fixed bug in character set conversion of BER strings. Bug introduced
382 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
384 For OID class, use oid_class consistently.
386 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
389 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
390 character set for bibliographic information interchange". By Giannis Kosmas.
392 Added documentation on new OID API.
396 Changes to generic frontend server interface: added new member
397 'query_charset' for bend_initrequest structure. A backend init handler
398 should set this member to its native character set for query terms.
399 When defined, the frontend server logic will announce this character set
400 to a client if the negotiationModel bit is set by the client. All server
401 implementors are encouraged to specify this. If a backend server does not
402 specify this a warning is issued using yaz_log(YLOG_WARN,..).
404 Added CCL utility to remove terms (stop words) from resulting RPN
405 tree. This is handled by functions with prefix ccl_stop_words_ .
407 New ZOOM C option, "rpnCharset", which allows client-side conversion of
408 terms in RPN queries.
410 Clean-up the CCL API. Moved some internal structures from ccl.h to
411 private header cclp.h. Changed ccl_parser_create so that a Bibset must
412 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
413 This is replaced by ccl_parser_find_str which takes a string instead.
415 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
416 libyaz.la is the core of YAZ except the generic frontend server and
417 does not depend on POSIX threads anymore. libyaz_server.la is the
418 generic frontend server facilities and uses POSIX thread functionality
419 if available. The libyaz.la no longer depends on POSIX threads because
420 the number of global structures is limited. NMEM no longer re-uses blocks
421 between threads ; it simply free's memory immediately but allocates in
422 "large" chunks as usual. We don't expect any performance penalties
423 because of this. The yaz_log system is still using a global log_level so
424 caution must be taken when modifying it with yaz_log_init_.. +
425 yaz_log_mask_str. This, however, should not cause any trouble because
426 these functions are called during initialization of application code
427 anyway. `yaz-config --libs server` returns libs for server applications;
428 `yaz-config --libs` returns libs for non-server applications.
430 New OID database - with public definitions in oid_db.h. Removed old OID
431 database including the head oid.h and definitions such as enum oid_value
432 and struct oident. The new OID database uses the same string names as
433 before but the 'protocol' is gone. There are now only two representations
434 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
435 converts from string to OID; functions with prefix yaz_oid_to_string
436 converts the other way.
438 Change to emit_term() in CQL-to-PQF query translation: when a term has
439 the /regexp relation modifier, do not process it for leading and
440 trailing "^" and "*", which have quite different meanings in regular
443 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
444 write handlers no longer carries a 'last' parameter. This will make
445 yaz_iconv flush "less" characters. A flush is performed by call to
446 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
448 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
449 removed, because function yaz_query_to_wrbuf does the same.
451 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
452 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
454 Deprecated MARC utility functions removed.
456 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
459 Branch split: YAZ_2_1_55_branch
461 --- 2.1.54 2007/03/16
463 Fix to ZOOM-C so that transparent reconnection is properly handled on
464 connections that are in asynchronous mode.
466 Fixed compilation on OpenBSD 4.0.
468 Large strings in GRS-1 records are now properly displayed in yaz-client.
470 Added character conversion support for "advancegreek"; based on patch from
473 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
474 sequence is met. Before the error was not set so it would be unknown.
476 Adjust yaz-marcdump MARC reader so that it skips until record separator
479 --- 2.1.52 2007/03/07
481 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
482 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
483 fd_set structure used as a bitmask for the FDs to be selected on.
485 Using ACX_PTHREAD macro to check for POSIX threads.
487 Fixed have-vsnprintf check.
489 --- 2.1.50 2007/02/23
491 Fixes for configure on BSD. Bug #900.
493 Added snprintf/vsnprintf wrappers for systems that don't have
494 limits (heavens forbid).
496 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
497 created before all previous tasks were completed and removed from the
498 task queue, the new task could be removed by a mistake.
500 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
502 Implemented pass-through CQL-to-PQF conversions. Bug #861.
504 Fixed bug #832: Problem with MARC/charset in yaz-client.
506 Fixed bug #668: save command line history for yaz-client.
508 Fixed bug #830: pkg-config support.
510 --- 2.1.48 2007/01/23
512 Extended ZOOM result set options with two options that may be read by
513 a client: resultSetStatus and presentStatus with values as specified for
515 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
517 Fixed bug #827: Using SSL fails on Debian etch.
519 Fixed bug #826: Weird looking chars for set of MARC records.
521 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
522 that is treated as an ItemOrder with itemRequest being an XML document
523 external. The value of "doc" is the content.
525 Extended the GFS search facility. New member of bend_search_rr
526 'estimated_hit_count' signals that hits is known to be an estmate
527 (higher or lower than real hit count). New member 'partial_resultset'
528 signals that the search was partial (hit count is lower or equal than
529 real hit count). For Z39.50, the information is stored in resultSetStatus
530 member of SearchResponse APDU. For SRU, the information is signalled
531 via SRU diagnostic 59: "Result set created with valid partial results
534 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
536 --- 2.1.46 2007/01/13
538 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
540 Added ZOOM_connection_peek_event.
542 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
543 the following new functions:
544 ZOOM_event_nonblock, ZOOM_connection_process,
545 ZOOM_connection_get_{socket,mask,timeout},
546 ZOOM_connection_fire_event_{timeout,socket}.
547 The existing blocking event handler, ZOOM_event, is a wrapper for the
548 + blocking ZOOM_event_sys_{poll,select}.
550 Implemented function ccl_xml_config which parses XML version of CCL
551 configuration (bug #798).
553 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
555 Added timings utility (yaz/timing.h)
557 --- 2.1.44 2007/01/03
559 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
562 Fixed bug #779: Rotation of apdu.log fails.
564 Fixed for character set conversions:
565 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
566 Honor G1 set in MARC-8 decoding.
568 --- 2.1.42 2006/12/17
570 Fixed bug #775: char conversion does not handle Alternative UTF-8
573 Implemented function yaz_marc_read_line which parses MARC line format
574 records. There is a wealth of formats out there. So far, this function
575 reads line records produced by yaz_marc_write_line.
577 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
578 more generic and easier to remember(!) options: -i format and -o format
579 which specifies input format and output format respectively - where
580 format is one of "marc", "marcxml", "line", "marcxchange".
582 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
583 does not print anything except warnings for records.
585 For yaz-marcdump, added support for MARC split into files (-s) with a given
588 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
589 spec, at http://www.loc.gov/standards/sru/record-update/
590 This has changed the binary layout of the following structs:
591 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
592 bend_update_rr . Patch by Ko van der Sloot.
594 Added GFS utility function bend_assoc_is_alive which returns 1 if
595 association is still alive (client is connected); 0 otherwise (client
596 closed connection). This allows busy servers to stop working for
599 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
600 been a separate piece of software. This version of ziffy has been modified
601 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
603 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
605 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
606 Client code may now interrogate options such as "init_opt_sort" to
607 find out whether the server claims to support various options.
609 --- 2.1.40 2006/11/27
611 Added utilities yaz_{set,get}_esn to set/get element set name from
614 Removed the build of libyazthread.la. The libyaz.so is the threaded version
615 of YAZ and has been so since YAZ 2.1.10.
617 Implemented ZOOM_record_error which returns error information for
618 record (surrogate diagnostic).
620 --- 2.1.38 2006/10/31
622 Updates for SRU Update by Ko van der Sloot:
623 1. Changed name from "operation" to "action"
624 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
625 versions in the code, marked as 'backward compatible'.
626 3. Added diagnostics for SRU Update.
628 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
630 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
632 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
634 For GFS, fixed problem with SRU diagnostic 'First record position out of
635 range' being issued for 0 hits.
637 zoomtst10 part of Windows Build.
639 --- 2.1.36 2006/10/13
641 Implemented yaz_filepath_comp which splits a path into file path
642 components (required by Zebra 2.0.3+).
644 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
645 BSD inspired license until now so this should not have any real impact on

648 Fixed bug #687: Missing log lines.
650 Fixed bug #678: CQL to PQF translation does not preserve double-quote
653 Fixed bug #689: SRU diagnostics to be added.
655 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
656 whether a connection is idle (no more work do do).
658 --- 2.1.34 2006/10/04
660 Change type of optval from long to int for invocation of setsockopt with
661 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
663 Added support for specifying the max log file size for the Generic
664 Frontend Server. The size is given with option -r.
666 --- 2.1.32 2006/09/21
668 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
670 --- 2.1.30 2006/09/17
672 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
675 Fixed bug in Generic Frontend Server that could cause a server to stop
676 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
678 For the generic frontend server, the maximum record size is used as maximum
679 size of incoming packages (SRU + Z39.50). The value until was previously
680 only used in Z39.50 Init negotiation and, later, in a session controlled
681 sizes of records returned. This is controlled using -k option. It can be
682 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
684 --- 2.1.28 2006/09/04
686 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
689 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
691 New option for yaz-marcdump -lpos=value which allows setting a portion
692 of MARC header to a certain value.
694 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
696 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
697 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
699 --- 2.1.26 2006/08/15
701 Fixed problem with SRU mode type (soap, get, post) for yaz-client
704 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
706 --- 2.1.24 2006/08/08
708 Fixed MARC ISO2709 encoding routines to deal with character set
711 Minor changes to GFS logging. Database included in search request log
714 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
715 cached/multiple records.
717 Shared libraries are built by default on Unix+configure.
719 Changed cql2pqf transformation to use a different evaluation order. The
720 new order is: always, relation, structure, position, truncation, index
721 and relationModifier. Old order was: always, relation, relationModifier,
722 structure, index, position, truncation. Note that the the latter ones
723 override former ones for identical attributes.. The new scheme means that
724 it is possible to override any existing attribute with a relationModifier.
725 And also that it is possible to override everything for the index rule
726 (except the ones listed in relationModifier). No order is perfect but this
727 one, we believe, covers more real cases.. The "always" should have been
728 called "default", since the attributes there can be overridden with all
731 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
732 compilation phase, but also for yaz-config --cflags output. This allows
733 us to have public headers with Libxml2 stuff in them . It should also,
734 eventually, make Libxml2 checks redundant in packages using YAZ, such
737 --- 2.1.22 2006/06/15
739 Changed SRU update structure bend_update_rr so that SRU diagnostics are
740 stored in uri, message and details.. Previously diagnostics were stored
741 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
742 compatibility.. but he's probably the only one affected, so.
744 Added support for CCL, compiled on the client side, in ZOOM-C. This
745 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
746 input; the resulting query objects can be used for for searching with
747 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
749 YAZ' configure searches for OpenSSL by default.
751 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
752 SL_CTX_use_certificate_file. See
753 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
754 for more info. Thanks to Ko van der Sloot.
756 --- 2.1.20 2006/06/02
758 Bug #600: SRU GET, POST support for yaz-client. Introduced
759 command 'sru' which selects method SOAP/GET/POST.
761 Allow missingValueAction to be specified for the sortspec string -
762 function yaz_sort_spec. By default, the missing value action is null.
763 Use ! to specify "abort". Use = followed by stringvalue to specify default
766 Ensured that Present-handler (if defined) is called in GFS before any call to
767 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
768 searchRetrieve requests.
770 Documentation for YAZ is now based on the Docbook XML/XSLT using
771 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
772 is no longer depending on jade/openjade or docbook-to-man scripts.
773 PDF is no longer part of the distribution - but can optionally be
774 made using DSSSL/jadetex or FOP.
776 Added retrieval handling support in Generic Frontend Server to support
777 conversion between MARC/XML as well as XSLTtransforms. See
778 etc/yazgfs.xml for an example.
780 Added Authentication support to Generic Frontend Server in SRU
781 mode. Authentication using HTTP Basic is supported, as is the use
782 of 'x-username' and 'x-password' parameters in the request itself.
784 Added support for a new character set MARC8s identical to MARC8 except
785 that it converts combined characters to single Unicode characters in the
786 Latin-1 range (when possible).
788 --- 2.1.18 2006/04/24
790 ASN.1 compiler 0.4: generates brief Doxygen file header for
791 generated .h/.c files.
793 Utility yaz_iconv now supports conversion to MARC-8.
795 New facilities for the MARC module. The reading - and writing of
796 content are separate methods for the yaz_marc_t handle. The following
797 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
798 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
799 format). Write functions have prefix yaz_marc_write_.. The existing
800 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
801 available. Removed support for OAI-MARC and simplexml (not the
802 simplexml from PHP5).
804 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
805 to be returned for this connection.
807 --- 2.1.16 2006/03/31
809 Allow multiple languages and charsets to be specified with
810 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
811 negcharset iso-8859-1,utf-8
813 Translation of proximity nodes from CQL into PQF now works.
815 Moved to automake 1.8, 1.9.
817 Added function yaz_log_set_handler which allows a log handler to be
818 installed. This handler will be called for all log messages. Output
819 to file is also produced; but that can be disabled by passing NULL
820 fname to yaz_log_init_file.
822 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
824 For SRW (including GFS), accept application/soap+xml as content-type
827 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
828 produces NO stylesheet reference even if a default stylesheet is specified
831 --- 2.1.14 2006/03/14
833 Updated Windows package to include yazd.dll + yazd.lib for the
834 Development component.
836 If the environment variable YAZ_LOG is set, then it is used as a
837 string indicating the default level of logging to use if not
838 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
839 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
840 used as before. So, for example, to omit warnings from YAZ logging,
843 cql_transform() now map structure and other attributes before indexes,
844 so that index-specific structures and other attributes can override
845 defaults. So now a combination of mapping specifications such as:
847 index.dc.date = 1=date-modified 4=5
848 does the right thing.
850 cql_transform() now also respects the "always" mapping specification,
851 which establishes an initial set of attributes to be used for all
852 terms except where overridden by more specific attributes associated
853 with the index, relation or modifier.
855 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
856 which mode to use; one of "post", "get" or "soap" (SRW, default).
858 Fixes for yaz_iconv routines: changed trie-based character set conversions
859 to use only non-negative values for bit fields due to Sun's C compiler not
860 supporting negative values.
862 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
863 sequences where not read correctly. Fix by Rustam Usmanov.
865 Updated win/makefile to use options, settings which makes things
866 compile with VS C 2005.
868 --- 2.1.12 2006/02/01
870 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
872 In ZOOM socket code, use select instead of poll on MacOSX.
874 ZOOM-C now support client-side compilation of CQL into RPN that is
875 sent to the server, enabling CQL to be used against all Z39.50
876 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
877 ZOOM_query object, and submit it using ZOOM_connection_search().
878 The CQL-to-RPN translation uses a configuration file, the name of
879 which must be specified in the Connection's "cqlfile" option.
881 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
882 function, which takes as its start-term parameter a ZOOM_query object
883 (which may have had either CQL or RPN set into it).
886 --- 2.1.10 2005/11/29
888 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
889 GFS to support this as well. Backend handler, bend_srw_update, does the
890 update work. Code contributed by Ko van der Sloot.
892 Allow retrieval of Search Result-1 information in ZOOM by the use of
893 options that are attached to a result set. ZOOM documentation updated
896 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
897 UTF-8 conversion. Patch by Raj Patel.
899 Added option -m to GFS to control formatting of timestamps in log file.
901 Added 'exit' as synonym for 'quit' in yaz-client
903 Added support for specifying SRW resultSetId + resultSetIdleTime in a
904 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
905 for the new members. Patch by Ko van der Sloot.
907 Added support for SRU POST. It is supported for content-type
908 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
910 Do not build the separate Multi-threaded (MT) library libyazthread.la.
911 Instead make the library libyaz.la multi-threaded. Threading as a whole
912 can still be disabled by configure option --disable-threads. Previosly,
913 with older GLIBCs there were problems with MT libs under Apache. This
914 has now been fixed a long time ago.
916 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
919 CQL module modified to be case insensitive for relations/indexes/operations.
921 Fixed bug in CQL transform code: incorrect value relationModifieder
924 Added 'show all' command for yaz-client which retrieves all results
927 Added new yaz-client, xmles, which takes a (private) OID and
928 a document to be sent as an extended service request.
930 Describe new yaz-client commands wait_response and set_auto_wait.
932 Increase TCP/IP listener backlog from 3 (which I am guessing was
933 copied from the SunOS manual entry way back when) so SOMAXCONN, so
934 that the socket will queue as many incoming connections as it's able
935 to handle ongoing connections. In other words, it will never now
936 refuse a connection that it would be able to handle merely because
937 it's not got around to accepting() enough of the pending connections
938 yet. This is the behaviour anyway under Linux, where the listen()
939 argument is ignored; but not under BSD and on systems such as
940 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
941 YAZ-based servers should now be uniform across operating systems in
944 yaz-marcdump uses 64-bit file access on some systems. This is enabled
945 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
946 This allows yaz-marcdump to read large MARC batches (>2 GB).
948 Modified all YAZ source files - except the source which is auto-generated
949 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
952 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
953 corresponding to the existing *_setl() function. These allow option
954 values containing arbitrary valuues.
956 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
957 ZOOM_resultset_sort() in new applications. Its behaviour is identical
958 except that it returns an indicator of whether or not the sort
959 criterion was accepted (0 for OK, -1 for invalid).
963 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
964 MARC output rather than returning "new" buffer.
966 yaz-client warns about unknown init options.
968 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
972 Added support for SRW sort in Generic Frontend Server. Patch
973 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
974 sortKeys - or NULL if none is provided.
976 Fixed bug #307: It was impossible to specify indefinite/no timeout
977 for ZOOM_event. Special timeout value -1 now means indefinite timeout
980 Added support for multiple languages and charsets to be specified in
981 ZOOM. Each charset/language is separated by a blank. If negotiation is
982 in effect in init-response, Option
983 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
984 Code based on patch by Vasiliy Osadchuk.
986 Fixed bug #306: infinite recursion that occurred when calling
987 yaz_log_level_init as the first call (before other log level or
990 Fixed bug in scan handling in front end server: if preferred-Position-In-
991 Response was non-present, a NULL pointer referece was performed.
995 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
996 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
997 now defined for all those error codes. So instead of putting 109 in
998 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
999 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1001 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1004 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1006 Program yaz-client now exits and produces an error message if multiple
1007 Z39.50 servers are specified on the command line (none or one allowed
1010 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1013 --- 2.1.2 2005/03/16
1015 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1017 Fixed bug #272: Preserve spacing for CCL terms.
1019 --- 2.1.0 2005/03/14
1021 Added support for virtual hosts and multiple backend servers for
1022 the YAZ frontend server. The configution is XML based and
1023 support specificition of CQL to RPN mappings and explain information.
1024 See section "Virtual Hosts" in the YAZ manual.
1026 Extended OPAC display utility. OPAC display utility renders
1027 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1028 to supplement yaz_marc_decode_wrbuf.
1030 Fixed a bug in MARC decoder that could caused it to crash for some
1031 invalid MARC records. More diagnostics and warnings where added in
1032 XML output (warnings, etc are stored in comments).
1034 --- 2.0.34 2005/02/08
1036 Fixes for UNIX domain sockets. Bug #261.
1038 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1040 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1041 Added yaz_marc_subfield_str which defines subfield lead string which is
1042 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1043 yaz_marc_endline_str which defines end of fields string used in
1044 YAZ_MARC_LINE format. Default string is newline.
1046 Experimental support for MarcXChange. This format can be produced
1047 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1048 http://www.bs.dk/standards/MarcXchange.xsd
1050 Added yaz-client commands scansize that sets maximum number of
1051 entries to be returned by scan.
1053 --- 2.0.32 2005/01/11
1055 Added support for SRW scan in yaz-client and Generic Frontend Server.
1057 * Added whereInList member to SRW Scan Term.
1059 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1061 Fixed NMEM system to return aligned blocks on the smallest boundaries
1062 that are suitably aligned for all possible types on the particular
1063 architecture YAZ is being built for.
1065 --- 2.0.30 2005/01/04
1067 Fixed numerious warnings that was issued with newer versions of GCC.
1069 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1070 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1073 Make YAZ Generic Frontend Server slightly faster.
1075 Enhance (and reduce) logging for Generic Frontend Server.
1077 Revert YAZ log system so that it flushes every write operation
1078 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1080 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1081 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1082 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1083 will effectively disable old definitions.
1085 --- 2.0.28 2004/11/09
1087 Added yaz_log_time_format which specifies log format using
1090 Added yaz_log_module_level which returns mask for a module. Value
1091 is non-zero mask a if module is enabled; zero if disabled.
1093 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1094 in include/yaz/cql.h.
1096 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1098 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1100 Fixed bug #172: RPM builds does not enable SSL.
1102 Doxyfile.in part of dist. Doxyfile generated by configure.
1104 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1105 are given and the corresponding component does not exist.
1107 Extend CCL documentation in YAZ reference. Describe r=r.
1109 --- 2.0.26 2004/10/01
1111 Fixed MARC->MARCXML conversion to properly deal with
1112 fields, subfields, indicators having non-ASCII characters.
1114 Fixed MARC->MARCXML conversion so that ASCII control characters
1115 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1118 Added YAZ GFS support for conversion from Z39.50 surrogate
1119 diagnostics to SRW surrogate diagnostics.
1121 Bug fix: YAZ GFS did not return schema in explainResponse.
1123 --- 2.0.25 2004/09/30
1125 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1126 now converts recordSchema to elementSetName as well as schema URI.
1128 Fixed bug in COMSTACK that prevented HTTP request packages from being
1131 --- 2.0.24 2004/09/29
1133 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1134 does not require white-space before and after the dash in a range, e.g.
1135 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1138 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1139 due to new GCC removing "redundant" code.
1141 Added yaz-client commands scanpos and scanstep that sets preferred
1142 position and step-size for scan.
1144 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1146 Added CCL utility ccl_qual_buf which parses one or more CCL
1147 spec lines in a buffer.
1149 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1150 of name and value - ignoring empty lines and comments.
1152 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1154 Added odr_get_element_path which returns current element path for an
1155 ODR handle. This utility is useful in error handling or user-defined
1158 Added ODR_PRINT utility odr_set_stream which is is a more generic
1159 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1160 to a write function and pointer to close function. The close function - if
1161 non-NULL - will be called during odr_destroy.
1163 Fixed bug in CCL parser where truncation char was not removed from
1164 right side when truncation=both was in effect.
1166 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1169 --- 2.0.23 2004/08/11
1171 Fix buffer overrun in CQL parser when dealing with proximity (%).
1173 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1174 to UTF-8/UCS conversion is now only based on codetables.xml.
1176 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1178 --- 2.0.22 2004/08/06
1180 Add support for more "commit changes" in ZOOM (uses Extended Services).
1182 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1185 Yet another small fix for configure of SSL.
1187 --- 2.0.21 2004/05/14
1189 Fix SSL libs for configure when --with-openssl=DIR is given.
1191 --- 2.0.20 2004/05/10
1193 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1195 SSL comstack now uses yaz.pem certificate file on server side
1196 by default. Certificate filename can be configured by calling
1197 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1199 Fix bug regarding multiple calls to ZOOM_connection_connect.
1201 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1203 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1204 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1206 ZOOM now allows inspection of X509 peer certificate for verification.
1207 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1209 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1210 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1211 as "modular" but it simplifies things.
1213 Added cs_get_peer_certificate to that returns peer X509 PEM.
1215 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1216 NULL if SSL is unavailable.
1218 Documentation about MARC decoding tools.
1220 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1222 --- 2.0.19 2004/03/30
1224 Rename CHANGELOG to NEWS to follow GNU style packing.
1226 Fix bug with missing initialization of member in init_diagnostics.
1227 This bug affects threaded version of GFS server.
1229 --- 2.0.18 2004/03/20
1231 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1234 Ensure zlib.dll is packed with Windows install.
1236 --- 2.0.17 2004/03/17
1238 Fix encoding of xsd:string to use text instead of CDATA.
1240 Fix endless loop in CQL parser with unbalanced ".
1242 Use a more compact way to store MARC-8 conversion tables.
1244 --- 2.0.16 2004/03/16 Debian only
1246 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1249 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1254 --- 2.0.15 2004/03/01
1256 Another fix for decoding of XML packed records.
1258 --- 2.0.14 2004/02/25
1260 Fixes for Chunked encoding. White space not ignored after length spec.
1262 Update NS and use default NS for SRW diagnostic elements.
1264 --- 2.0.13 2004/02/23
1266 Implement ZOOM_resultset_cache_reset which resets record cache.
1268 Implement ZOOM_resultset_sort which sorts a result set.
1270 Implement chunked HTTP transfer.
1272 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1274 --- 2.0.12 2004/02/16
1276 Added member 'schema' to bend_explain_rr structure so that backend
1277 can specify explain record identifier. Defaults to Zeerex 2.0.
1279 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1281 --- 2.0.11 2004/02/16
1283 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1286 Added init command for yaz-client which sends "extra" init request.
1288 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1289 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1291 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1293 Make ZOOM error code for "invalid query".
1295 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1297 --- 2.0.10 2004/02/05
1299 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1302 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1304 Added option -p <file> to make Generic Frontend Server to write PID file.
1306 Added option -D to put Generic Frontend Server in background on its own.
1308 Make ZOOM C recognize option "password". If unset, "pass" is used
1309 (for backwards compatibility).
1311 Fixed a bug in Generic Frontend Server that could make it crash if a
1312 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1315 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1316 Must be issued before open, in order to be in effect.
1318 --- 2.0.9-6 2004/01/12 Debian/Windows
1320 Make the SRU server more picky WRT unknown params, etc.
1322 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1324 New YAZ client command, options, that sets Z39.50 options.
1326 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1327 options from a string of tokens (one token for each option bit).
1329 Update SRW diagnostic code messages.
1331 --- 2.0.9-5 2004/01/07 Debian/Windows
1333 Handle user defined stylesheet for SRW/SRU.
1335 --- 2.0.9-4 2004/01/06 Debian/Windows
1337 Fix bug in decoding of Content-Length.
1339 --- 2.0.9-3 2004/01/06 Debian/Windows
1341 Fix a bug with decoding of XML packed records.
1343 --- 2.0.9-2 2004/01/05 Debian only
1345 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1347 Fix bug in SRW/SRU diagnostics decoding.
1349 --- 2.0.9 2004/01/05
1351 Fixed bug in Generic Frontend Server which could drop records exceeding
1352 preferred message size. Reported and fixed by Irina Dijour.
1354 Fixed calculation of package size for structured records in Generic
1355 Frontend Server. Reported and fixed by Irina Dijour.
1357 Fixed namespace for SRW/SRU diagnostics.
1359 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1361 --- 2.0.8 2003/12/22
1363 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1364 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1367 CQL changes to reflect recent changes to the specification:
1368 * Documentation talks about context sets instead of index sets.
1369 * Documentation talks about indexes instead of qualifiers.
1370 * The CQL-to-PQF transformer's configuration file now uses
1371 "index.set.name = <attributes>" instead of the old form
1372 "qualifier.set.name = <attributes>". (Both forms are still
1373 understood but the latter is deprecated.)
1374 * CQL terms with no explicit index specified are now interpreted as
1375 cql.serverChoice instead of srw.serverChoice (which of course
1376 behaves exactly the same.)
1378 --- 2.0.7 2003/12/16
1380 MARC conversion can now generate ISO2709 output in another
1381 character set. yaz-marcdump uses this facility if you invoke it
1384 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1385 functions from there can be used from C++.
1387 --- 2.0.6 2003/12/04
1389 Frontend server now transfers memory from decoded packages to stream
1392 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1393 references to show up.
1395 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1396 the ZOOM Abstract API. The older names for the same options are still
1397 also supported for the benefit of old applications.
1399 ZOOM-C supports "implementationId" and "implementationVersion" options
1400 to go along with "implementationName". These allow the user code to
1401 specify identification strings to be sent to servers.
1402 Add OID for the new ExtLite attribute set.
1404 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1405 as requested/supplid by Ere Maijala <ere@atp.fi>
1407 For generic frontend server, reverse the order of
1408 "toolkit-supplied / application-supplied" strings sent as implementationId,
1409 Name and Version. Also, remove the spaces around the slash. This brings
1410 the GFS in line with the behaviour of ZOOM-C on the client side.
1412 Add function ZOOM_scanset_display_term.
1414 yaz-client shows scan displayTerm if present.
1416 Utility yaz-iconv is now installed by default along with the man page
1419 Extend configure check for OpenSSL to use pkg-config where available (such
1422 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1423 server to specify uid/gid/mask for socket using the format
1424 unix:[user=uid,][group=gid,][umask=mask,]file=path
1425 If file= is omitted the existing format is assumed, e.g.
1427 in which case the mask is 0666 (rw for everybody).
1429 Major restructure of YAZ source. All source in libyaz is in src directory.
1430 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1431 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1433 Added man page for utility yaz-marcdump (used to be called marcdump).
1434 yaz-marcdump is installed by 'make install'.
1436 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1437 of incoming package failed.
1439 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1441 Change prototype of odr_perror: add const to message string.
1443 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1445 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1446 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1447 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1448 DNS lookup. There should not be any compatibility problems with this
1449 assuming that blocking=1 or 0 is used.
1451 Fix bad reference in UNIX comstack in function cs_addrstr.
1453 Fix for compilation on AIX.
1455 The generic front-end server (server/seshigh.c) now supports returning
1456 Init diagnostics to the client in User-information-field, in
1457 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1460 --- 2.0.4 2003/09/04
1462 Allow any CQL relation (not just all,any,exact,scr).
1464 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1465 that features the same UI.
1467 Implemented command update0 in YAZ client which is equivalent to
1468 update but uses old of Ext Update ASN.1.
1470 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1471 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1472 Previously no OID was used for this info.
1474 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1475 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1476 returns 'malformed search term' otherwise.
1478 SortResponse member resultCount now set to NULL in sort handler of
1481 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1484 Add three new utility functions for translating OIDs between various
1485 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1486 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1487 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1488 char *oid_to_dotstring(const int *oid, char *oidbuf);
1489 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1491 Reverted modifications for ES Update definition for z_IU0Update
1492 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1493 is back to YAZ 2.0.2.
1495 String value attributes for CCL parser.
1497 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1498 which their FirstSearch server returns in Init responses, sometimes
1499 carrying useful diagnostic information when Init fails. This has the
1500 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1501 "z39.50/oclcui.asn", where its definition is somewhat different from
1502 what OCLC document on their web-site, as required to interoperate with
1505 Support for anonymous authentication in yaz-client. Use the command
1508 * Fix the OID of the Index Data-local "admin" Extended Service from
1509 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1510 the 1000, which indicates a locally-defined OID, was a mistake.
1512 --- 2.0.3 2003/06/20
1514 Fix CCL directive @case handling so that it affects string match for
1515 both CCL keywords and qualifiers.
1517 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1518 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1519 Decoder has been updated with ASN.1 changes as listed in
1520 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1521 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1522 z_IUUpdate, remains unchanged.
1524 ZOOM_record_get may now return a record in a specific character set.
1525 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1526 "from" is the character set of record as returned by target. "to" is
1527 the character set to be returned. If omitted, "to" is UTF-8.
1529 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1531 New ODR utility, odr_getelement, which returns name of element for
1532 which encoding/decoding failed.
1534 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1535 in cases where a required element was omitted.
1537 Bug fix: some MARC8 sequences were not converted.
1539 New ZOOM option "step" which specifies number of records to be
1540 retrieved in one chunk. Used in conjunction with "start" and "count".
1542 SRW support for yaz-client. Use scheme http: to use it, e.g.
1545 yaz-client no longer does (un)intelligent character set conversions
1546 by default. Can be enabled with charset and marc_charset commands.
1548 xmalloc trace fix for 64-bit systems such as DEC alpha.
1550 Solaris 2.6 compile fix.
1552 New function, cql_strerror() translates SRW error codes, as returned
1553 by cql_transform_error(), into human-readable English strings. Used
1554 in yaz-client diagnostics when appropriate.
1556 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1557 converts it into a type-1 query which is sent to the server. This
1558 makes CQL available for use with all Z-servers, as opposed to the tiny
1559 minority that can handle CQL queries themselves.
1561 --- 2.0.2 2003/04/28
1563 New Debian package layout similar to the Redhat Package layout.
1565 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1566 and search result respectively.
1568 --- 2.0.1 2003/04/25
1570 Redhat package is now several packages: libyaz (runtime libraries),
1571 libyaz-devel (development and documentation, and yaz (utility programs).
1572 Package spec file by Morten Bogeskov.
1574 New member 'schema' in struct bend_fetch_rr which the name of requested
1575 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1576 handler MAY set this to reflect the schema of the returned record.
1578 New member 'display_term' in struct scan_entry. GFS now sets member entries
1579 and allocates scan entries to be filled by user scan handler. In previous
1580 version, entries member was allocated by the scan handler. That still works,
1581 but the GFS will ignore member display_term - assuming it was NOT set by
1582 the handler. The fact that the GFS now allocates the entries both allows
1583 for new members and makes a scan handler easier to write.
1585 Fix CQL lex buffer overflow.
1587 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1588 SRU default recordPacking is string.
1590 SRU protocol support for frontend server.
1592 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1594 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1596 Added scan for the ZOOM shell (zoomsh).
1600 * String Identifers for Schemas (Amendment 5).
1601 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1602 Old definition for schema
1603 Odr_oid *schema; /* OPT */
1608 Z_InternationalString *uri;
1609 #define Z_Schema_oid 1
1610 #define Z_Schema_uri 2
1613 * resultCount parameter to Sort Response (Amendment 1).
1614 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1616 Support for SRW 1.0 over HTTP. This is an optional feature and
1617 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1620 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1621 on the same port. SRW SearchRetrieveRequests are mapped
1622 to bend_init,bend_search,bend_fetch,bend_close.
1624 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1626 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1627 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1629 ZOOM connections are SRW based if schem http is used for hostname
1630 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1631 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1633 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1634 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1635 distance=n, order=true/false, relation=le, prox unit=word. If
1636 n is omitted, distance 1 is used.
1638 Fixed problem with C compiler include path in wrong order.
1640 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1641 on Solaris. Patch from Ko van der Sloot.
1643 New MARC decode API. All new functions operate on a yaz_marc_t
1644 handle. The most important new functions are: yaz_marc_create,
1645 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1646 decode and destroy respectively. Decoder can produce formats
1647 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1648 include/yaz/marcdisp.h.
1650 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1651 to UTF-8, UCS-32, wchar_t or Latin-1.
1653 * Prototypes for yaz_iconv_-functions moved to separate header
1654 include/yaz/yaz-iconv.h.
1656 Make a few private functions 'static' in unix.c. This prevents
1657 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1659 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1660 are set when Init Response is received.
1662 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1663 but returns diagnostic set as well.
1665 New function yaz_strerror which is a portable wrapper for
1666 strerror/strerror_r/GetLastMessage.
1668 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1669 is returned for MARC. If type is "oai", then OAI MARC is returned.
1671 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1674 --- 1.9.2 2002/11/26
1676 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1678 Fix bad race conditions on SIGTERM and terminate gracefully in
1681 Move retrieval (data1) module to Zebra since nobody seems to be
1684 Add GRS-1 render for ZOOM using same format as yaz-client.
1686 --- 1.9.1 2002/10/05
1688 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1690 Fix broken ESpec handling in data1 module.
1692 SGML reader parses comments and makes them part of the data1 tree.
1694 Added several type casts so that YAZ compiles as C++ code.
1696 ZOOM didn't handle PDU encoding failures properly.
1698 Added more Bib-1 diagnostics (approved extensions).
1700 GNU configure: better check for iconv.
1702 More portable use of accept, getpeername. Check for socklen_t. Use
1703 int/size_t if socklen_t is not defined.
1707 PQF parser rejects bad queries - including those with extra
1708 characters in them. PQF parser used to silently ignore that.
1709 Cleaner API for PQF added, which allows you to get detailed
1710 error information for bad queries (see yaz/pquery.h).
1712 Fixed bug in ZOOM_record_get for type "database".
1714 Implemented mini iconv library supporting conversions between
1715 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1717 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1719 --- 1.8.9 2002/08/20
1721 Fixed ZOOM C record cache so that preferredRecordSyntax and
1722 elementSetName is used to check for already fetched records.
1724 --- 1.8.8 2002/08/02
1726 Added three members in bend_initrequest structure to facilitate
1727 character set negotiation.
1729 Fixed a bug in frontend server that could cause indefinite
1730 loops under rare conditions.
1732 Revised character set utilities (charneg.h) so that encoding
1733 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1735 For PQF, directive @term <type> sets term type for Scan/Search.
1736 Here <type> is general, string, numeric, null. The term type
1737 is inherited - just like @attr.
1739 New call odr_set_charset that sets character set conversion for
1740 international-strings on a ODR stream. Prototype is:
1741 int odr_set_charset(ODR o, const char *to, const char *from);
1742 The InternationalString is still represented as C string in YAZ
1743 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1744 won't). On the protocol level, you can use any encoding.
1746 Support for UNIX sockets in ZOOM.
1748 Solaris recv sometimes returns errno == ENOENT. It is treated as
1749 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1751 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1752 both client and server. Code by Morten Bogeskov.
1754 --- 1.8.7 2002/05/22
1756 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1757 that they can be used directly from Visual Basic. You must recompile
1758 your windows APP if you're using ZOOM.
1760 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1761 Commands "lang" and "charset" sets language and character set respectively.
1762 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1763 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1765 Attributes from multiple CCL fields may be OR'ed rather than merged
1766 using directive "@field or". Fields are still merged by default -
1767 equivalent to "@field merge".
1769 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1772 Fixed bug in zget for parameter ExtendedServicesResponse.
1776 --- 1.8.6 2002/03/25
1778 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1780 Client displays USR.1:SearchResult-1 (hits per term).
1782 Additional Search Info for search in Generic Frontend Server.
1784 Fixed CCL parsing of "field=s".
1786 WIN32 installer - using the excellent NSIS software from nullsoft.
1788 Fixed CCL parsing of "field = - <number>".
1790 Added function yaz_marc_decode that decodes MARC for line mode
1791 display or XML (similar to that used by JZKit).
1793 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1794 Z39.50. But ISO/ILL was, however.
1796 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1797 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1799 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1800 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1802 --- 1.8.5 2002/02/03
1804 New YAZ client features: Command completion and new commands:
1805 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1806 Code provided by Jacob Poulsen.
1808 New call oid_trav, that visits all registered OIDs via callback.
1810 Function ZOOM_record_get now returns const char pointer rather than
1811 void pointer. It saves a lot of type casts.
1813 For YAZ client, command "auth" now allows you to set authentication
1814 in IdPass style. It is enabled when three tokens are given - order
1815 is user, group and password.
1817 Fix memory leaks in MARC record handling for ZOOM.
1819 New option for YAZ client, -k <kilobytes> that sets
1820 maximum record size. Similar to -k option for generic frontend
1821 server and yaz-ztest.
1823 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1825 Prefix query parser reports "fail" when bad attribute set is given.
1827 Fix in MARC decoder. Proximity logging. Fix for attribute set
1828 in scan handler for server. Patches by Shigeru Ishida.
1830 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1833 Configure option --with-openssl=<dir> now works when a directory is
1834 specified. Patch provided by Morten Bogeskov.
1836 New option for YAZ client, -u <auth>, that sets authentication.
1838 ZOOM fix: error information was sometimes "missing", since error
1839 was cleared/reset too when it shouldn't.
1841 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1843 --- 1.8.4 2002/01/04
1845 Scan for ZOOM API. New object ZOOM_scanset. New functions
1846 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1847 ZOOM_scanset_destroy.
1849 New ZOOM function, ZOOM_connection_last_event, that returns type
1850 of last event (such as "receive data", "send data", "apdu received",
1853 New ZOOM option, schema, that specifies schema for retrieval.
1855 New CCL feature. Qualifiers can be aliases for one or more
1856 other qualifiers (if more than one is given, OR is used).
1858 ZOOM uses named result sets if target supports it.
1860 Two new YAZ client commands: . (dot, which sources a script of YAZ
1861 client commands), and ! (to execute shell command.). Implemented
1864 Working on Debian packages.
1866 --- 1.8.3 2001/11/19
1868 YAZ client enables named result sets only if target supports it.
1870 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1872 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1873 with key="host" to get same result.
1875 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1876 Function Z3950_resultset_record(s) returns references to records
1877 "owned" by resultset. To become owner use Z3950_record_clone.
1879 Function z_ext_record handles Extended Services. Thanks to
1882 --- 1.8.2 2001/11/12
1884 CCL Parser fix: ignore token comma when dealing with and-lists.
1886 Documentation updates for COMSTACK.
1888 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1889 Changed prototype Z3950_records. For some functions, int parameters
1890 were changed to size_t.
1892 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1895 New MARC decode/display function, marc_display_exl, which properly rejects
1896 non-ISO2709 records. YAZ client uses it.
1898 --- 1.8.1 2001/10/29
1900 Fix bug: local attribute set wasn't set correctly in PQF strings.
1904 * Old Z39.50 codecs no longer supported.
1906 Added ZOOM C binding. See http://zoom.z3950.org/
1908 Renamed states for COMSTACKs to avoid confusion with events.
1910 Implemented cs_look and proper cs_rcvconnect.
1912 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1914 Configure detects POSIX threads on OpenBSD.
1916 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1917 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1919 When error is returned from present handler, non-surrogate diagnostic
1920 is returned in present response (and fetch handler is no longer called).
1922 * Minor adjustments to pquery parser (PQF). Token characters may be
1923 escaped by using backslash (C-style).
1925 PQF parser allows string attribute values to be specified. For @attr,
1926 non-numeric characters after the equal-sign are treated as strings
1927 (e.g. @attr 9=title).
1929 CCL trunction character may be defined (@truncation in file)
1931 * function zget_ExtendedServicesRequest sets waitAction to
1932 waitIfPossible (was wait).
1934 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1937 CCL operator names may be set in field definition files (CCL_bibset).
1938 See ccl/bib1 for an example.
1940 Fixes in ASN.1 compiler for C++ compatibility.
1942 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1943 and "op_or" to avoid conflict with C++.
1945 Fixed problem with GNU readline detection on Redhat 7.0.
1947 Added step-size for Scan backend handler.
1949 Fixed bug that made the frontend server crash when no attribute
1950 set was specified for scan.
1952 Front-end server automatically switches to original working directory
1953 when installed as an NT service. Previously -w had to be specified to
1956 Added extended attributes for retrieval module (data1), so that data1
1957 records carry d1_readXML/SGML attributes. d1_read also supports
1958 null-data rules ( <tag/>)
1960 On UNIX when POSIX threads are available, a separate library libyazthread
1961 is created. Programmers should link with that library and the yaz library
1962 when using threads. The reason for the split was that some applications
1963 on Linux, such as Apache, doesn't work well when using shared objects that
1966 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1967 (or any frontend server) in SSL mode by specifying ssl: followed by
1968 address. Only tested on UNIX.
1970 Added feature for CCL module. Virtual structure s=al or s=ol generates
1971 and-list and or-list respectively instead of phrase search.
1975 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1976 log_mask_str. This was done to avoid name conflicts with other libraries
1977 (such as other PHP extensions).
1979 Added raw OID member for preferred record syntax (request_format_raw)
1980 and returned record syntax (output_format_raw) for backend fetch method.
1982 Config file yaz-config now accepts options so that it returns specific
1983 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1985 Shared library support for UNIX using GNU libtool.
1987 * Modified backend interface. Request/Response struct's replaced by
1988 one read/write C struct. For example bend_fetchrequest and
1989 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1990 Every handler - even search has to be registered in bend_init
1991 handler. This means that the YAZ library no longer refers to
1992 external functions and it makes it possible to make the whole
1993 thing a single DLL/SO.
1995 Added Segment handler for backend server.
1997 Added Zmbol/Zebra administrative functions to YAZ client.
1999 Threaded frontend server on UNIX (when POSIX Threads are available).
2000 Starting the server with option -T enables multi-threading.
2004 Added configure option --enable-comp/disable-comp to control use
2005 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2006 located in sub directory asn.
2008 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2009 in ${exec_prefix}/bin along with the other programs yaz-client and
2012 GNU automake used to maintain makefiles.
2014 Added several OID's.
2016 Changed retrieval module so that we can load records with no abstract
2017 syntax defined. Tagpaths in these records are fully composed of string
2020 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2024 On UNIX, the generated makefile now supports a proper 'make install'.
2025 The prefix can be set via GNU configure to set the install location
2026 (default is /usr/local).
2028 * YAZ programs client and ztest were renamed to yaz-client and
2029 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2030 locations, such as /usr/bin,/usr/local/bin,etc.
2032 * YAZ Header files were moved from include to include/yaz. YAZ Header
2033 files are referred to as include <yaz/log.h> rather than <log.h>.
2034 The YAZ include path (-I ..) is therefore the same as before. Programmers
2035 should update their #include statements or use -Ipath/include/yaz
2036 instead. The main motivation for doing this change is that YAZ header files
2037 can be installed in "standard" locations /usr/include,/usr/local/include
2038 without introducing conflicts, since ALL YAZ header files are stored
2039 in subdirectory yaz (under /usr/include for example).
2041 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2042 rather than project/workspace files. We switched because project files
2043 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2046 Changed name of logging function, logf, to yaz_log, to prevent name
2047 clash with some math-log functions. The YAZ header log.h defines logf
2048 to yaz_log (#define) so there should be no incompatibilities by this
2051 Added bend_start/bend_stop handlers for server. These handler are
2052 called on start/stop of server. For windows they are called whenever
2053 a service is started/stopped.
2055 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2056 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2057 in util/yc.tcl. The auto-generated C code structures are, in a few
2058 cases, incompatible with the old decoders. There are differences in the
2059 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2060 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2061 The preprocessor variable ASN_COMPILED is defined when the compiled
2062 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2063 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2064 wish to use the old encoders/decoders you can specify --disable-yc
2067 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2068 version so that it supports both new - and old version of DB Update
2070 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2071 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2072 change. The name parameter can be set to 0 in which no name is specified
2073 for the construction. The macros odr_implicit and odr_explicit sets name
2074 parameter to zero for the construction involved. New macros
2075 odr_implicit_tag and odr_explicit_tag are similar to the others,
2076 except that a name parameter is added. For programmers' that don't use
2077 ODR they probably only need to change the call to z_APDU and z_External.
2079 Added access control facility by interfacing the TCP wrapper library.
2080 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2081 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2082 name of the daemon and enables the access control as specified in
2083 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2085 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2086 den Dool <H.M.vdnDool@kub.nl>.
2088 Added reference ID parameter to most functions in server API - refer
2089 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2091 Changed name of ccl library to libccl.a (was ccl.a).
2093 Fixed bug in decoder for Explain (Category TargetInfo).
2095 Added support for GNU readline in client. Thanks to Jacob Poulsen
2096 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2098 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2099 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2100 IMPLEMENTATION! This change was made to the development version before
2101 the ZIG decided to retract the amendment. If any users MUST be
2102 compatible with the original Update definition, PLEASE CONTACT US, and
2103 we will include a separate definition corresponding to the old Update
2104 ES. Note that because of the change to the ASN.1 of the
2105 TaskPackageRecordStructure we cannot define a single structure that
2106 will support both versions.
2108 * Added const modifier to buffer parameter for some ODR/BER encoding
2109 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2110 completeWAIS, odr_dumpBER.
2112 Fixed bug in client.c which caused a crash when a scanResponse didn't
2113 contain positionOfTerm.
2115 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2116 * will cause an error in a client if a non-YAZ target sends both a
2117 * list of Scan entries and non-surrogate diagnostics.
2119 Retrieval module enhancements. Tag sets may be typed in the reference
2120 to it. From the .abs-file the "tagset" directive takes a third optional
2121 integer type for the tag set referenced. From a .tag-file the "include"
2122 directive takes a third optional type as well. The old "type" directive
2123 in the tag set itself is still recognized but acts as the default type
2126 Backend interface change. Individual Scan terms returned from bend_scan
2127 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2128 in include/backend.h.
2130 Retrieval module enhancements. Multiple tag sets and attribute sets may
2131 be specified in abstract syntax specs. Revised the error/warning for
2132 logging messages reported by the retrieval module when reading the
2135 Object Identifier system (oid_..) changed. The API is backwards
2136 compatible but the oid-routines now allocates new OID's when needed.
2137 Raw OID's may be specified in oid_getvalbyname.
2139 YAZ now uses GNU configure to generate Makefile(s).
2141 * Minor changes in some of the member names of DeleteResultSetRequest and
2142 DeleteResultSetResponse. See include/proto.h.
2144 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2145 and added member 'languages' in TargetInfo (which was missing).
2147 Changed the way attribute sets are handled in the retrieval
2148 module. These are now cached, just like the abstract syntaxes
2151 Changed YAZ so that it links with compiled ASN.1.
2153 Added Explain-schema definitions and mapping routines. The following
2154 Explain categories have been implemented: AttributeDetails,
2155 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2157 Fixed minor bug in Windows version of Server Library.
2159 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2161 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2163 Added EXTERNAL: UNIverse Resource Report (non-standard).
2165 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2166 ENUMERATED and SET OF.
2168 * Added 'const' to some of the char pointer arguments for the
2169 functions, data1_read_node, data1_getelementbytagname,
2170 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2173 Fixed bug in data1_insert_taggeddata - the last_child member of
2174 parent wasn't initialised.
2176 * Changed data1_read_record and data1_read_node so that the supplied
2177 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2178 doesn't refer to any parts of the "SGML"-buffer.
2180 Fixed bug in server library (Windows version of statserv_remove).
2182 * Changed code so that it compiles as C++. The type definition
2183 of Odr_fun which is a member of Odr_arm was changed. The result is,
2184 that an explicit typecast is needed for the fun pointer when
2185 using Odr_arm - as in:
2186 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2188 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2190 Implemented the new structured date and time definition as approved
2191 by the ZIG. Added schemaId element to the specificTag in Espec-1
2192 (also approved at the last ZIG). Thanks to RVDM.
2194 Added some Object identifiers (RVDM).
2196 Changed the Update Extended Service (RVDM).
2198 Added command "refid" to client which specifies referenceId for
2199 the following requests.
2201 Implemented extended service handling for server. See ztest.c
2202 for an example as well as backend.h. New handlers are registerd
2203 in the Init handler.
2205 * Changed interface for sort in server.
2207 Added new members to statserv_options_block. It allows a server
2208 to read options from another source than just the command line. Thanks
2209 to Charles Woodfield.
2211 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2212 renamed to zboolean. Some C++ compilers complained about the name.
2214 Minor changes to gils.abs. Added index 's' (sort) on title
2215 and date/time-last-modified.
2217 --- 1.4pl2 1998/1/30
2219 Fixed bug in server library regarding inetd mode (-i). This bug
2220 was introduced by release 1.4.
2222 --- 1.4pl1 1998/1/29
2224 Added sort facility in client and backend server interface.
2226 Fixed problem with dependencies in Makefile(s).
2228 Fixed bugs for encoders/decoders of extended services and
2231 Implemented sub-tree feature for schemas. Sub-trees are
2232 referenced in *.abs-files. See explain.abs for an example
2233 of the use of this feature.
2235 Modified bib1.att; local attributes for ANY didn't include
2236 ANY itself (only affects use of the retrieval module).
2238 Fixed bug in plain SGML reader in function data1_read_node:
2239 tags with prefix "var" was incorrectly interpreted as variants.
2241 Added feature "sub-schemas" to enable references to - and definitions
2242 of - group of elements.
2244 * Removed member parent from type data1_element (in data1.h).
2246 Implemented function odr_nullval() that returns the value of
2249 * Removed member num_children from data1_node (in data1.h).
2251 Made NT service interface part of the server library. The
2252 function statserv_main uses the NT service when required and
2253 calls the statserv_start / statserv_close routines.
2255 Routine zget_SearchRequest and zget_PresentRequest fills
2256 resultSetName/Id member with "default" instead of "Default".
2258 Fixed memory leak in server. Request queue member wasn't freed.
2260 Fixed nmem_exit so that memory is freed.
2264 Revised the CCL parser utility to be thread safe.
2266 Added function, oid_ent_to_oid, to replace the function
2267 oid_getoidbyent, which is not thread safe.
2269 * Added nmem_init and nmem_exit to initialize and release
2270 NMEM resources. Function nmem_init should be called once in the
2271 initial thread before NMEM/ODR is used. statserv.c and client.c
2272 have been changed accordingly. The change was necessary to make
2273 NMEM thread safe. The NMEM memory pool is shared amongst threads
2274 in a process. Unix-based applications will still work fine without
2277 Added NT Services interface for the the Z39.50 (statserv) Server.
2278 Refer to the ztest.c source on the usage.
2280 Windows 95/NT port using MSVC5.0. Project files are included in the
2283 * Defined new 'global' handle for the retrieval (data1) system. The
2284 new handled, data1_handle, describes the state of the data1 system.
2285 This handle is passed as first argument to virtually all
2286 data1 related routines. The functions data1_create and data1_destroy
2287 creates and destroys a data1 handle respectively.
2289 Added ODR encode stream member to all backend request structures
2290 init, search, scan etc. This stream should be used to allocate all
2291 memory used for the response when thread safe operation is needed.
2293 Changed the comstack utility, cs_addstr, to be thread safe. The
2294 returned hostname string returned by the function is now part the
2297 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2298 function. The cs_straddr takes a COMSTACK handle as argument, so this
2299 function must be used after cs_create and before bind/connect.
2300 This function is thread safe.
2302 Moved test server to 'ztest' directory - generic server code still
2303 in 'server' directory.
2305 Made prefix query (pquery.c) utility thread safe.
2307 Added new function modifier YAZ_EXPORT to 'export' public DLL
2308 functions when using windows (see include/yconfig.h).
2310 Added definitions to the OID database (util/oid.c) (RVDM).
2312 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2314 Added call to ccl_rpn_delete in client program.
2316 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2317 release of RPN structure.
2319 Added support for C++, headers uses extern "C" for public definitions.
2320 With input from RVDM.
2322 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2323 Thanks to Ronald van der Meer (RVDM).
2325 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2327 Added support for private extensions to the OID database
2328 (oid_setprivateoids()). Thanks to RVDM.
2330 Added optional, physical ANY (key replication)
2332 Fixed null-reference problem in GRS-1 output filter.
2334 Proximity operator added to Prefix Query Format (PQF).
2336 In test client command "base" accepts multiple databases.
2338 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2342 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2344 Smallish bug-fixes in the new encoders/decoders (explain).
2346 Bug fixed in DeleteRequest.
2348 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2350 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2352 Added SOIF syntax (using private OID for now) to retrieval module and client.
2354 Added Update extended service.
2356 Added SearchResult-1 additional info structure.
2358 Added optional CCL (ISO8777) interpreter as separate module. Available
2361 --- 1.2 1996/6/10 (1st anniversary release)
2363 Added Summary record syntax. Lightly tested.
2365 Added OPAC record syntax. Untested.
2367 Added ResourceReport service encoders/decoders. Untested.
2369 Fixed bug in z_Unit - wrong tagging on unitSystem.
2371 Fixed bug in the DiagRecs decoder.
2373 Added options for max PDU size and session timeout to frontend-server.
2375 Added documentation of query-language parsers and other supporting utilities.
2377 [frontend-server] Added Attribute set to the bend_scanrequest API.
2379 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2380 surrogate diagnostics were generated.
2382 [retrieval] Allow multiple local values for attribute.
2384 [retrieval] Allow multiple attributes per element in .abs files. index type.
2386 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2388 --- 1.1pl2 1996/4/10
2390 Minor changes, mostly specific to Zebra's requirements (retrieval)
2394 Repaired bug in frontend server when running multiple listening
2395 endpoints in dynamic mode.
2397 z_External() now won't break if a known, ASN.1 value comes encapsulated
2398 in an octet-string. The value will pass through unmodified in an Odr_oct.
2400 Added a bit of code to the demo client to decode & display
2401 ASN.1-structured records represented in the octet-aligned branch of
2402 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2404 Added z_ext_getentbyref() to the ASN module. Doc updated.
2406 * Completed the SCAN definition in the ASN module. This may break SCAN
2407 code based on older YAZ-versions at compile-time. The fix is easy -
2410 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2411 under the SCAN definition. Remember to initialize this, server-people.
2413 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2414 that this does not extend to ODR and ASN.
2416 Comstack allows insertion of established socket (primarily for
2417 inetd-operation of servers). Doc updated.
2419 Front-end server can now start from the inetd in TCP mode. Doc
2422 --- 1.0pl4 1996/1/24
2426 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2427 the rank and record number.
2429 Adjustments to the frontend server.
2431 Fixed diagnostic BER dumper. It ignored the file argument.
2435 Various changes to retrieval module.
2437 Changed the union discriminators of the protocol files from enums to
2438 ints paired with #defines.
2440 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2443 *Changed operator in the RPN structure to 'roperator', again to avoid a
2446 Fixed problems in Explain decoders/encoders.
2448 --- 1.0pl2 1995/12/6
2450 Memory bug in log module fixed.
2452 --- 1.0pl1 1995/12/5
2454 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2456 Bug in Explain DatabaseInfo module fixed.
2458 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2462 The shift to v1.0 signals that we now consider the *core* functionality
2463 of YAZ reasonably stable (the core being more or less equivalent to
2464 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2465 tested (Explain not at all - though that will happen soonish).
2467 Minor changes to code to support Windows port.
2469 Various minor changes after we're getting to use GRS-1 & co. more.
2471 Added Espec-1 format.
2473 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2474 of the protocol and it cannot be selected when encoding (maps into 'string'
2475 when decoding). Needed to talk to some servers.
2477 Demo client can request simple element set names.
2479 Added Diagnostic Format encoders/decoders.
2481 Added simple Close handling to frontend server (no hooks for resource
2482 reporting yet), and demonstration client.
2484 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2486 --- 1.0b3 1995/08/24
2488 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2489 handled incorrectly when records were requested in the searchResponse. This
2490 will only affect you if you use the frontend-server.
2492 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2493 Test-client will ask for and print GRS1. Ztest will return dummy records
2496 Added Explain encoders/decoders to the service-level API. Untested.
2498 Added Extended Services: Item Order encoders and decoders to the Service-
2499 level API. Untested. We could use a recent copy of the pertinent bits
2500 of the ILL protocol to add those bits.
2502 Added diagnostic format 1 encoders/decoders to the service-level API.
2505 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2506 odr_cons.c, which causes a more correct output.
2508 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2509 was always set to 0 when no records were requested in the searchRequest.
2511 * Added better external-handling. This shouldn't harm old code that
2512 *encodes* externals. It can break code that looks for a
2513 'single-ASN1-type' representation, since those types that are known
2514 are now decoded immediately. Look at the SUTRS sample code in
2515 seshigh.c and client.c. Documentation updated.
2517 Handling of structured records in bend_fetchresponse. Length -1 marks
2518 structured record, type is deduced from format field.
2520 --- 1.0b2 1995/06/27
2521 Fairly quick maintenance release to add SUTRS support.
2523 Fixed handling of SUTRS records in the demonstration client.
2525 * Added format field to the bend_fetchrequest and bend_fetchresponce
2526 structures of the backend API (frontend server). When the record is
2527 returned, the value of the format field is mapped to an OID. The
2528 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2529 of the record. The special value VAL_NONE in the bend_request means
2530 that no specific format was requested by the client. Documentation
2531 updated accordingly. Test server (ztest) will return a fixed dummy
2532 SUTRS record if your client requests SUTRS.
2534 Documentation updated accordingly.
2536 You can now set external libraries and RANLIB support in the top-level
2540 First public release.
