1 List supported encodings in man page for yaz-iconv.
3 Fixed missing SSL libs for --libs output
5 Re-established OID record syntax application-xml. Nobody should use it
6 but we don't want to change soname because of this symbol being absent.
10 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
12 Added member named_result_sets for init handler struct for the GFS. This
13 allows a server to disable named result sets.
15 Removed OID record syntax application-xml.
17 Added support for rule-based transliterator for ICU wrapper of YAZ.
19 Fixed bug #1902: yaz-icu XML output.
21 Make YAZ checks Emacs friendly.
23 BITSTRING value shows value. Bug #2346.
25 ISO2709 decoding: skip control characters from indicator data.
27 Omit sort key by default in yaz-icu's output.
29 Allow combined single char options (again) for YAZ' options function.
31 Utility yaz-marcdump got option to display YAZ version (-V).
33 Allow YAZ to use ICU 3.4.
35 Added new ICU test case which illustrates removal of diacritics.
39 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
43 For configure, using option --without-xml2 also disables Libxslt/Libexslt
46 Fixed bug #2352: yaz-marcdump crashes for certain record.
48 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
50 Added support for Danmarc2 to UTF-8 conversion.
52 Added support for ISO5426 to UTF-8 conversion.
54 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
55 implementation version.
57 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
61 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
62 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
64 ZOOM C now interprets databaseName option for ZOOM connection as path
67 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
69 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
71 Dummy Libxml2 types no longer defined in headers of YAZ'.
73 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
78 Various ODR chapter fixes.
80 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
82 Added missing source for Windows compilation, mutex.c.
84 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
86 For SRU connections in ZOOM all records up to "count" are now fetched.
88 Fixed crash in generic frontend server (and yaz-ztest) which occurred
89 in Windows due to bad error handling for Libxml2.
91 Added facility for sending arbitrary records (ASN.1 any) using
92 ZOOM C's Extended service update. Patch by Sam Reynolds.
94 New options for ZOOM C's connection, logapdu which makes ZOOM log
99 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
101 --- 3.0.32 2008/06/12
103 Fixed memory violation that could occur when decoding UTF-8. This bug
104 was only present in 3.0.30 of YAZ.
106 --- 3.0.30 2008/06/06
108 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
109 GNU TLS is used by default (if found).
111 yaz-ztest returns OPAC records if a client asks for OPAC.
113 Improved speed of MARC-8 encoding.
115 Added support for lossy and loss-less MARC-8 encoding.
117 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
119 Added new Windows Service wrapper (sc).
121 yaz-client's itemorder command may now send a file.
123 Fixed yaz-marcdump to allow the use of NS prefix for record element.
125 Added new function yaz_log_xml_errors.
127 Allow (but warn) unknown XML attributes in MARCXML parsing.
129 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
131 The UTF-8 to MARC-8 conversion now uses a different set of characters
132 for Greek symbols. Bug #2120.
134 --- 3.0.26 2008/02/21
136 Added yaz_daemon (daemon.h).
138 Fixed bug #2068: pkg-config trouble
140 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
142 --- 3.0.24 2008/01/28
144 Document --with-xml2 option.
146 Added OPAC XML XSD (etc/opacxml.xsd).
148 Allow glob mask for name attribute in retrieval element for the
149 generic frontend server's retrieval facility.
151 Changed yaz_poll_poll to return yaz_poll_except for all returned events
152 except POLLIN/POLLOUT.
154 Fixed error handling in cs_listen. Bug #2037.
156 --- 3.0.22 2008/01/20
158 Fixed version in yaz/yaz-version.h.
160 Fixed bug #2027: Crash when closing connection.
162 Changed configure so that ICU support is only enabled if only ICU
163 and Libxml2 is available (because the ICU chain is XML based).
165 --- 3.0.20 2008/01/15
167 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
168 is built. Only this DLL depends on the ICU runtime.
170 yaz-ziffy is no longer part of YAZ. It is distributed separately by
171 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
173 Changed license of CCL module to 'Revised BSD'. After consultation with
174 remaining members of the original EUROPAGATE consortium, we are re-issuing
175 the CCL module without a separate license. The software was developed by
176 Index Data as part of a research project. The special license was included
177 to help feed usage information back to the project consortium to support
178 project evaluation. At this time, the project consortium has long-since
179 disbanded, and the majority of the original principals have retired. At the
180 same time, we have significantly modified the software during the following
181 years, to the point where very practically no original code remains. To
182 simplify re-use of the software, we have contacted those members of the
183 consortium who could be reached, and agreed to re-issue the module as a
184 proper part of the YAZ package.
186 Tcl scripts uses /usr/bin/tclsh as preferred shell.
188 CQL closer to being version 1.2 compliant. CQL also allows free-form
189 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
192 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
193 bug could make Extended services handling crash in the ZOOM layer. This
194 bug was only present in YAZ 3.0.18.
196 --- 3.0.18 2007/12/19
198 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
201 yaz-marcdump reads and writes collection wrapped records.
203 Handle OPAC for record conversion module.
205 Fixes for ICU wrapper.
207 Allow ICU libs to be controlled with --with-icu .
209 --- 3.0.16 2007/11/12
211 Added yaz_poll which is a wrapper for select/poll. When poll is available
212 and non-buggy, it is used, by yaz_poll . This allows more than 1024
213 sockets to be in use.
215 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
216 functionality through an XML based configuration (ICU chain). This system
217 is useful for search facilities such as Pazpar2 and Zebra that needs to
218 perform tokenization of indexed material. The ICU code in a separate
219 library libyaz3_icu.a.
221 Added HTTP tunnel facility for COMSTACK, bug #1752.
222 This is a facility that allows a Web proxy, such as squid, to tunnel
223 Z39.50 traffic. This facility is "transparent" to must applications
224 using YAZ. It's enabled by using pseudo transport connect: followed by
225 the proxy address, followed by command, then follwed by he regular
226 "virtual" addresss. For example,
227 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
229 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
231 --- 3.0.14 2007/09/21
233 Fixed bad memory reference in ZOOM_record - cuased by member not being
234 initialized. This was a problem only in YAZ 3.0.12.
236 Fixed bug in conversion from MARC to XML: Non-XML characters in control
237 fields were not removed.
239 Changed the way C code is generated from codetables.xml. Made a MARC-8
240 conversion trie for each characterSet section rather than codeTable.
241 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
242 of codetables.xml from Larry Dixson, LOC. Bug #1464.
244 --- 3.0.12 2007/09/12
246 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
247 from ZOOM_record_error).
249 ZOOM C function ZOOM_record_get returns record schema for type="schema".
251 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
253 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
255 Better SRW-to-Bib-1 diagnostic mapping.
257 ZOOM C and yaz-client announces SRU version 1.2 by default.
259 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
262 Fixed in yaz_sru_decode to allow other version than 1.1.
264 --- 3.0.10 2007/08/22
266 Added support for SRU scan for ZOOM.
268 Added support for the use of the older versions or Extended Service
269 Update in ZOOM. To faciliate this, an option "updateVersion" may be
270 set to the version , 1=first, 2=second, 3=third. The third version is
271 what ZOOM C has used so far. And that, obviously, is the default.
273 Added support for CCL queries in Z39.50 queries sent to the GFS (and
274 therefore in Zebra and in SimpleServer-based applications). The new
275 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
276 qualifier file used to transform incoming CCL queries into Type-1 RPN,
277 which is passed into the back-end search callback function.
279 Added support for HTTP Basic authentication in clients: the SRU/W
280 codec encodes the username/password elements of the PDU structure
281 appropriately, and these may be set using the "user" and "password"
282 options in ZOOM-C applications (the same options that are used for
283 Z39.50 authentication).
287 Fixed bug #1208: SSL appears to be broken in ZOOM.
289 Fixed bug #1206: Libxml2 include path weirdness.
291 Added oid_name_to_dotstring.
293 Allow elementSetName to be specified for ZOOM C record update.
295 Allow waitAction to be specified for ZOOM C based for Extended Services.
297 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
298 syntax OID. Bug introduced in YAZ 3 series.
300 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
304 Fixed bug #1157: yaz-client does not read .yazclientrc from current
305 directory. yaz-client now reads commands from file given by option -f
306 if specified; then tries to read .yazclientrc in current directory.
307 Failing that, it reads .yazclientrc from user's home directory.
309 Added support for correlationInfo Note and ID for Record Update via
312 Added yaz-client command querycharset which specifies character set for
313 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
314 (termListAndStartPoint).
316 Charset ISO5428:1984 is an alias for ISO5428-1984.
318 Implemented a way to perform scan in a result set using Z39.50. This
319 is achieved by attaching the result set name in the characterInfo
320 (type InternationalString) of OtherInformation in the Scan Request PDU.
321 The result set is identified in the otherinformation by the new OID:
322 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
323 This allows for scan in result set and faceted search . Zebra did some
324 of this in the APT term using attribute type 8 and value being result
325 set. Using the OtherInformation approach for this is cleaner and easier
326 to work with in proxies and the like. This facility can be used in
327 yaz-client using new command setscan which takes a result set as first
328 argument, start position (APT) as second.
330 Changed decoding of SRU XML packed records to deal with servers that
331 have recordData with XML data with multiple root nodes. Also make
332 comparison for recordPacking case insensitive. Again, one server
333 returns "XML" where others return "xml".
335 For SRU responses allow Content-Type application/xml as well as text/xml.
339 Fixed bug in character set conversion of BER strings. Bug introduced
344 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
346 For OID class, use oid_class consistently.
348 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
351 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
352 character set for bibliographic information interchange". By Giannis Kosmas.
354 Added documentation on new OID API.
358 Changes to generic frontend server interface: added new member
359 'query_charset' for bend_initrequest structure. A backend init handler
360 should set this member to its native character set for query terms.
361 When defined, the frontend server logic will announce this character set
362 to a client if the negotiationModel bit is set by the client. All server
363 implementors are encouraged to specify this. If a backend server does not
364 specify this a warning is issued using yaz_log(YLOG_WARN,..).
366 Added CCL utility to remove terms (stop words) from resulting RPN
367 tree. This is handled by functions with prefix ccl_stop_words_ .
369 New ZOOM C option, "rpnCharset", which allows client-side conversion of
370 terms in RPN queries.
372 Clean-up the CCL API. Moved some internal structures from ccl.h to
373 private header cclp.h. Changed ccl_parser_create so that a Bibset must
374 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
375 This is replaced by ccl_parser_find_str which takes a string instead.
377 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
378 libyaz.la is the core of YAZ except the generic frontend server and
379 does not depend on POSIX threads anymore. libyaz_server.la is the
380 generic frontend server facilities and uses POSIX thread functionality
381 if available. The libyaz.la no longer depends on POSIX threads because
382 the number of global structures is limited. NMEM no longer re-uses blocks
383 between threads ; it simply free's memory immediately but allocates in
384 "large" chunks as usual. We don't expect any performance penalties
385 because of this. The yaz_log system is still using a global log_level so
386 caution must be taken when modifying it with yaz_log_init_.. +
387 yaz_log_mask_str. This, however, should not cause any trouble because
388 these functions are called during initialization of application code
389 anyway. `yaz-config --libs server` returns libs for server applications;
390 `yaz-config --libs` returns libs for non-server applications.
392 New OID database - with public definitions in oid_db.h. Removed old OID
393 database including the head oid.h and definitions such as enum oid_value
394 and struct oident. The new OID database uses the same string names as
395 before but the 'protocol' is gone. There are now only two representations
396 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
397 converts from string to OID; functions with prefix yaz_oid_to_string
398 converts the other way.
400 Change to emit_term() in CQL-to-PQF query translation: when a term has
401 the /regexp relation modifier, do not process it for leading and
402 trailing "^" and "*", which have quite different meanings in regular
405 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
406 write handlers no longer carries a 'last' parameter. This will make
407 yaz_iconv flush "less" characters. A flush is performed by call to
408 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
410 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
411 removed, because function yaz_query_to_wrbuf does the same.
413 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
414 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
416 Deprecated MARC utility functions removed.
418 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
421 Branch split: YAZ_2_1_55_branch
423 --- 2.1.54 2007/03/16
425 Fix to ZOOM-C so that transparent reconnection is properly handled on
426 connections that are in asynchronous mode.
428 Fixed compilation on OpenBSD 4.0.
430 Large strings in GRS-1 records are now properly displayed in yaz-client.
432 Added character conversion support for "advancegreek"; based on patch from
435 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
436 sequence is met. Before the error was not set so it would be unknown.
438 Adjust yaz-marcdump MARC reader so that it skips until record separator
441 --- 2.1.52 2007/03/07
443 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
444 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
445 fd_set structure used as a bitmask for the FDs to be selected on.
447 Using ACX_PTHREAD macro to check for POSIX threads.
449 Fixed have-vsnprintf check.
451 --- 2.1.50 2007/02/23
453 Fixes for configure on BSD. Bug #900.
455 Added snprintf/vsnprintf wrappers for systems that don't have
456 limits (heavens forbid).
458 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
459 created before all previous tasks were completed and removed from the
460 task queue, the new task could be removed by a mistake.
462 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
464 Implemented pass-through CQL-to-PQF conversions. Bug #861.
466 Fixed bug #832: Problem with MARC/charset in yaz-client.
468 Fixed bug #668: save command line history for yaz-client.
470 Fixed bug #830: pkg-config support.
472 --- 2.1.48 2007/01/23
474 Extended ZOOM result set options with two options that may be read by
475 a client: resultSetStatus and presentStatus with values as specified for
477 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
479 Fixed bug #827: Using SSL fails on Debian etch.
481 Fixed bug #826: Weird looking chars for set of MARC records.
483 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
484 that is treated as an ItemOrder with itemRequest being an XML document
485 external. The value of "doc" is the content.
487 Extended the GFS search facility. New member of bend_search_rr
488 'estimated_hit_count' signals that hits is known to be an estmate
489 (higher or lower than real hit count). New member 'partial_resultset'
490 signals that the search was partial (hit count is lower or equal than
491 real hit count). For Z39.50, the information is stored in resultSetStatus
492 member of SearchResponse APDU. For SRU, the information is signalled
493 via SRU diagnostic 59: "Result set created with valid partial results
496 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
498 --- 2.1.46 2007/01/13
500 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
502 Added ZOOM_connection_peek_event.
504 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
505 the following new functions:
506 ZOOM_event_nonblock, ZOOM_connection_process,
507 ZOOM_connection_get_{socket,mask,timeout},
508 ZOOM_connection_fire_event_{timeout,socket}.
509 The existing blocking event handler, ZOOM_event, is a wrapper for the
510 + blocking ZOOM_event_sys_{poll,select}.
512 Implemented function ccl_xml_config which parses XML version of CCL
513 configuration (bug #798).
515 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
517 Added timings utility (yaz/timing.h)
519 --- 2.1.44 2007/01/03
521 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
524 Fixed bug #779: Rotation of apdu.log fails.
526 Fixed for character set conversions:
527 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
528 Honor G1 set in MARC-8 decoding.
530 --- 2.1.42 2006/12/17
532 Fixed bug #775: char conversion does not handle Alternative UTF-8
535 Implemented function yaz_marc_read_line which parses MARC line format
536 records. There is a wealth of formats out there. So far, this function
537 reads line records produced by yaz_marc_write_line.
539 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
540 more generic and easier to remember(!) options: -i format and -o format
541 which specifies input format and output format respectively - where
542 format is one of "marc", "marcxml", "line", "marcxchange".
544 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
545 does not print anything except warnings for records.
547 For yaz-marcdump, added support for MARC split into files (-s) with a given
550 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
551 spec, at http://www.loc.gov/standards/sru/record-update/
552 This has changed the binary layout of the following structs:
553 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
554 bend_update_rr . Patch by Ko van der Sloot.
556 Added GFS utility function bend_assoc_is_alive which returns 1 if
557 association is still alive (client is connected); 0 otherwise (client
558 closed connection). This allows busy servers to stop working for
561 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
562 been a separate piece of software. This version of ziffy has been modified
563 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
565 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
567 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
568 Client code may now interrogate options such as "init_opt_sort" to
569 find out whether the server claims to support various options.
571 --- 2.1.40 2006/11/27
573 Added utilities yaz_{set,get}_esn to set/get element set name from
576 Removed the build of libyazthread.la. The libyaz.so is the threaded version
577 of YAZ and has been so since YAZ 2.1.10.
579 Implemented ZOOM_record_error which returns error information for
580 record (surrogate diagnostic).
582 --- 2.1.38 2006/10/31
584 Updates for SRU Update by Ko van der Sloot:
585 1. Changed name from "operation" to "action"
586 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
587 versions in the code, marked as 'backward compatible'.
588 3. Added diagnostics for SRU Update.
590 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
592 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
594 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
596 For GFS, fixed problem with SRU diagnostic 'First record position out of
597 range' being issued for 0 hits.
599 zoomtst10 part of Windows Build.
601 --- 2.1.36 2006/10/13
603 Implemented yaz_filepath_comp which splits a path into file path
604 components (required by Zebra 2.0.3+).
606 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
607 BSD inspired license until now so this should not have any real impact on
608 anybody. See http://www.opensource.org/licenses/bsd-license.php
610 Fixed bug #687: Missing log lines.
612 Fixed bug #678: CQL to PQF translation does not preserve double-quote
615 Fixed bug #689: SRU diagnostics to be added.
617 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
618 whether a connection is idle (no more work do do).
620 --- 2.1.34 2006/10/04
622 Change type of optval from long to int for invocation of setsockopt with
623 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
625 Added support for specifying the max log file size for the Generic
626 Frontend Server. The size is given with option -r.
628 --- 2.1.32 2006/09/21
630 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
632 --- 2.1.30 2006/09/17
634 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
637 Fixed bug in Generic Frontend Server that could cause a server to stop
638 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
640 For the generic frontend server, the maximum record size is used as maximum
641 size of incoming packages (SRU + Z39.50). The value until was previously
642 only used in Z39.50 Init negotiation and, later, in a session controlled
643 sizes of records returned. This is controlled using -k option. It can be
644 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
646 --- 2.1.28 2006/09/04
648 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
651 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
653 New option for yaz-marcdump -lpos=value which allows setting a portion
654 of MARC header to a certain value.
656 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
658 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
659 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
661 --- 2.1.26 2006/08/15
663 Fixed problem with SRU mode type (soap, get, post) for yaz-client
666 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
668 --- 2.1.24 2006/08/08
670 Fixed MARC ISO2709 encoding routines to deal with character set
673 Minor changes to GFS logging. Database included in search request log
676 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
677 cached/multiple records.
679 Shared libraries are built by default on Unix+configure.
681 Changed cql2pqf transformation to use a different evaluation order. The
682 new order is: always, relation, structure, position, truncation, index
683 and relationModifier. Old order was: always, relation, relationModifier,
684 structure, index, position, truncation. Note that the the latter ones
685 override former ones for identical attributes.. The new scheme means that
686 it is possible to override any existing attribute with a relationModifier.
687 And also that it is possible to override everything for the index rule
688 (except the ones listed in relationModifier). No order is perfect but this
689 one, we believe, covers more real cases.. The "always" should have been
690 called "default", since the attributes there can be overridden with all
693 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
694 compilation phase, but also for yaz-config --cflags output. This allows
695 us to have public headers with Libxml2 stuff in them . It should also,
696 eventually, make Libxml2 checks redundant in packages using YAZ, such
699 --- 2.1.22 2006/06/15
701 Changed SRU update structure bend_update_rr so that SRU diagnostics are
702 stored in uri, message and details.. Previously diagnostics were stored
703 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
704 compatibility.. but he's probably the only one affected, so.
706 Added support for CCL, compiled on the client side, in ZOOM-C. This
707 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
708 input; the resulting query objects can be used for for searching with
709 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
711 YAZ' configure searches for OpenSSL by default.
713 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
714 SL_CTX_use_certificate_file. See
715 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
716 for more info. Thanks to Ko van der Sloot.
718 --- 2.1.20 2006/06/02
720 Bug #600: SRU GET, POST support for yaz-client. Introduced
721 command 'sru' which selects method SOAP/GET/POST.
723 Allow missingValueAction to be specified for the sortspec string -
724 function yaz_sort_spec. By default, the missing value action is null.
725 Use ! to specify "abort". Use = followed by stringvalue to specify default
728 Ensured that Present-handler (if defined) is called in GFS before any call to
729 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
730 searchRetrieve requests.
732 Documentation for YAZ is now based on the Docbook XML/XSLT using
733 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
734 is no longer depending on jade/openjade or docbook-to-man scripts.
735 PDF is no longer part of the distribution - but can optionally be
736 made using DSSSL/jadetex or FOP.
738 Added retrieval handling support in Generic Frontend Server to support
739 conversion between MARC/XML as well as XSLTtransforms. See
740 etc/yazgfs.xml for an example.
742 Added Authentication support to Generic Frontend Server in SRU
743 mode. Authentication using HTTP Basic is supported, as is the use
744 of 'x-username' and 'x-password' parameters in the request itself.
746 Added support for a new character set MARC8s identical to MARC8 except
747 that it converts combined characters to single Unicode characters in the
748 Latin-1 range (when possible).
750 --- 2.1.18 2006/04/24
752 ASN.1 compiler 0.4: generates brief Doxygen file header for
753 generated .h/.c files.
755 Utility yaz_iconv now supports conversion to MARC-8.
757 New facilities for the MARC module. The reading - and writing of
758 content are separate methods for the yaz_marc_t handle. The following
759 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
760 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
761 format). Write functions have prefix yaz_marc_write_.. The existing
762 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
763 available. Removed support for OAI-MARC and simplexml (not the
764 simplexml from PHP5).
766 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
767 to be returned for this connection.
769 --- 2.1.16 2006/03/31
771 Allow multiple languages and charsets to be specified with
772 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
773 negcharset iso-8859-1,utf-8
775 Translation of proximity nodes from CQL into PQF now works.
777 Moved to automake 1.8, 1.9.
779 Added function yaz_log_set_handler which allows a log handler to be
780 installed. This handler will be called for all log messages. Output
781 to file is also produced; but that can be disabled by passing NULL
782 fname to yaz_log_init_file.
784 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
786 For SRW (including GFS), accept application/soap+xml as content-type
789 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
790 produces NO stylesheet reference even if a default stylesheet is specified
793 --- 2.1.14 2006/03/14
795 Updated Windows package to include yazd.dll + yazd.lib for the
796 Development component.
798 If the environment variable YAZ_LOG is set, then it is used as a
799 string indicating the default level of logging to use if not
800 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
801 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
802 used as before. So, for example, to omit warnings from YAZ logging,
805 cql_transform() now map structure and other attributes before indexes,
806 so that index-specific structures and other attributes can override
807 defaults. So now a combination of mapping specifications such as:
809 index.dc.date = 1=date-modified 4=5
810 does the right thing.
812 cql_transform() now also respects the "always" mapping specification,
813 which establishes an initial set of attributes to be used for all
814 terms except where overridden by more specific attributes associated
815 with the index, relation or modifier.
817 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
818 which mode to use; one of "post", "get" or "soap" (SRW, default).
820 Fixes for yaz_iconv routines: changed trie-based character set conversions
821 to use only non-negative values for bit fields due to Sun's C compiler not
822 supporting negative values.
824 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
825 sequences where not read correctly. Fix by Rustam Usmanov.
827 Updated win/makefile to use options, settings which makes things
828 compile with VS C 2005.
830 --- 2.1.12 2006/02/01
832 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
834 In ZOOM socket code, use select instead of poll on MacOSX.
836 ZOOM-C now support client-side compilation of CQL into RPN that is
837 sent to the server, enabling CQL to be used against all Z39.50
838 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
839 ZOOM_query object, and submit it using ZOOM_connection_search().
840 The CQL-to-RPN translation uses a configuration file, the name of
841 which must be specified in the Connection's "cqlfile" option.
843 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
844 function, which takes as its start-term parameter a ZOOM_query object
845 (which may have had either CQL or RPN set into it).
848 --- 2.1.10 2005/11/29
850 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
851 GFS to support this as well. Backend handler, bend_srw_update, does the
852 update work. Code contributed by Ko van der Sloot.
854 Allow retrieval of Search Result-1 information in ZOOM by the use of
855 options that are attached to a result set. ZOOM documentation updated
858 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
859 UTF-8 conversion. Patch by Raj Patel.
861 Added option -m to GFS to control formatting of timestamps in log file.
863 Added 'exit' as synonym for 'quit' in yaz-client
865 Added support for specifying SRW resultSetId + resultSetIdleTime in a
866 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
867 for the new members. Patch by Ko van der Sloot.
869 Added support for SRU POST. It is supported for content-type
870 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
872 Do not build the separate Multi-threaded (MT) library libyazthread.la.
873 Instead make the library libyaz.la multi-threaded. Threading as a whole
874 can still be disabled by configure option --disable-threads. Previosly,
875 with older GLIBCs there were problems with MT libs under Apache. This
876 has now been fixed a long time ago.
878 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
881 CQL module modified to be case insensitive for relations/indexes/operations.
883 Fixed bug in CQL transform code: incorrect value relationModifieder
886 Added 'show all' command for yaz-client which retrieves all results
889 Added new yaz-client, xmles, which takes a (private) OID and
890 a document to be sent as an extended service request.
892 Describe new yaz-client commands wait_response and set_auto_wait.
894 Increase TCP/IP listener backlog from 3 (which I am guessing was
895 copied from the SunOS manual entry way back when) so SOMAXCONN, so
896 that the socket will queue as many incoming connections as it's able
897 to handle ongoing connections. In other words, it will never now
898 refuse a connection that it would be able to handle merely because
899 it's not got around to accepting() enough of the pending connections
900 yet. This is the behaviour anyway under Linux, where the listen()
901 argument is ignored; but not under BSD and on systems such as
902 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
903 YAZ-based servers should now be uniform across operating systems in
906 yaz-marcdump uses 64-bit file access on some systems. This is enabled
907 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
908 This allows yaz-marcdump to read large MARC batches (>2 GB).
910 Modified all YAZ source files - except the source which is auto-generated
911 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
914 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
915 corresponding to the existing *_setl() function. These allow option
916 values containing arbitrary valuues.
918 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
919 ZOOM_resultset_sort() in new applications. Its behaviour is identical
920 except that it returns an indicator of whether or not the sort
921 criterion was accepted (0 for OK, -1 for invalid).
925 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
926 MARC output rather than returning "new" buffer.
928 yaz-client warns about unknown init options.
930 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
934 Added support for SRW sort in Generic Frontend Server. Patch
935 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
936 sortKeys - or NULL if none is provided.
938 Fixed bug #307: It was impossible to specify indefinite/no timeout
939 for ZOOM_event. Special timeout value -1 now means indefinite timeout
942 Added support for multiple languages and charsets to be specified in
943 ZOOM. Each charset/language is separated by a blank. If negotiation is
944 in effect in init-response, Option
945 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
946 Code based on patch by Vasiliy Osadchuk.
948 Fixed bug #306: infinite recursion that occurred when calling
949 yaz_log_level_init as the first call (before other log level or
952 Fixed bug in scan handling in front end server: if preferred-Position-In-
953 Response was non-present, a NULL pointer referece was performed.
957 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
958 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
959 now defined for all those error codes. So instead of putting 109 in
960 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
961 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
963 Modified the yaz-marcdump utility to skip garbage bytes between MARC
966 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
968 Program yaz-client now exits and produces an error message if multiple
969 Z39.50 servers are specified on the command line (none or one allowed
972 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
977 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
979 Fixed bug #272: Preserve spacing for CCL terms.
983 Added support for virtual hosts and multiple backend servers for
984 the YAZ frontend server. The configution is XML based and
985 support specificition of CQL to RPN mappings and explain information.
986 See section "Virtual Hosts" in the YAZ manual.
988 Extended OPAC display utility. OPAC display utility renders
989 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
990 to supplement yaz_marc_decode_wrbuf.
992 Fixed a bug in MARC decoder that could caused it to crash for some
993 invalid MARC records. More diagnostics and warnings where added in
994 XML output (warnings, etc are stored in comments).
996 --- 2.0.34 2005/02/08
998 Fixes for UNIX domain sockets. Bug #261.
1000 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1002 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1003 Added yaz_marc_subfield_str which defines subfield lead string which is
1004 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1005 yaz_marc_endline_str which defines end of fields string used in
1006 YAZ_MARC_LINE format. Default string is newline.
1008 Experimental support for MarcXChange. This format can be produced
1009 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1010 http://www.bs.dk/standards/MarcXchange.xsd
1012 Added yaz-client commands scansize that sets maximum number of
1013 entries to be returned by scan.
1015 --- 2.0.32 2005/01/11
1017 Added support for SRW scan in yaz-client and Generic Frontend Server.
1019 * Added whereInList member to SRW Scan Term.
1021 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1023 Fixed NMEM system to return aligned blocks on the smallest boundaries
1024 that are suitably aligned for all possible types on the particular
1025 architecture YAZ is being built for.
1027 --- 2.0.30 2005/01/04
1029 Fixed numerious warnings that was issued with newer versions of GCC.
1031 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1032 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1035 Make YAZ Generic Frontend Server slightly faster.
1037 Enhance (and reduce) logging for Generic Frontend Server.
1039 Revert YAZ log system so that it flushes every write operation
1040 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1042 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1043 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1044 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1045 will effectively disable old definitions.
1047 --- 2.0.28 2004/11/09
1049 Added yaz_log_time_format which specifies log format using
1052 Added yaz_log_module_level which returns mask for a module. Value
1053 is non-zero mask a if module is enabled; zero if disabled.
1055 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1056 in include/yaz/cql.h.
1058 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1060 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1062 Fixed bug #172: RPM builds does not enable SSL.
1064 Doxyfile.in part of dist. Doxyfile generated by configure.
1066 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1067 are given and the corresponding component does not exist.
1069 Extend CCL documentation in YAZ reference. Describe r=r.
1071 --- 2.0.26 2004/10/01
1073 Fixed MARC->MARCXML conversion to properly deal with
1074 fields, subfields, indicators having non-ASCII characters.
1076 Fixed MARC->MARCXML conversion so that ASCII control characters
1077 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1080 Added YAZ GFS support for conversion from Z39.50 surrogate
1081 diagnostics to SRW surrogate diagnostics.
1083 Bug fix: YAZ GFS did not return schema in explainResponse.
1085 --- 2.0.25 2004/09/30
1087 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1088 now converts recordSchema to elementSetName as well as schema URI.
1090 Fixed bug in COMSTACK that prevented HTTP request packages from being
1093 --- 2.0.24 2004/09/29
1095 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1096 does not require white-space before and after the dash in a range, e.g.
1097 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1100 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1101 due to new GCC removing "redundant" code.
1103 Added yaz-client commands scanpos and scanstep that sets preferred
1104 position and step-size for scan.
1106 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1108 Added CCL utility ccl_qual_buf which parses one or more CCL
1109 spec lines in a buffer.
1111 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1112 of name and value - ignoring empty lines and comments.
1114 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1116 Added odr_get_element_path which returns current element path for an
1117 ODR handle. This utility is useful in error handling or user-defined
1120 Added ODR_PRINT utility odr_set_stream which is is a more generic
1121 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1122 to a write function and pointer to close function. The close function - if
1123 non-NULL - will be called during odr_destroy.
1125 Fixed bug in CCL parser where truncation char was not removed from
1126 right side when truncation=both was in effect.
1128 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1131 --- 2.0.23 2004/08/11
1133 Fix buffer overrun in CQL parser when dealing with proximity (%).
1135 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1136 to UTF-8/UCS conversion is now only based on codetables.xml.
1138 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1140 --- 2.0.22 2004/08/06
1142 Add support for more "commit changes" in ZOOM (uses Extended Services).
1144 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1147 Yet another small fix for configure of SSL.
1149 --- 2.0.21 2004/05/14
1151 Fix SSL libs for configure when --with-openssl=DIR is given.
1153 --- 2.0.20 2004/05/10
1155 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1157 SSL comstack now uses yaz.pem certificate file on server side
1158 by default. Certificate filename can be configured by calling
1159 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1161 Fix bug regarding multiple calls to ZOOM_connection_connect.
1163 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1165 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1166 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1168 ZOOM now allows inspection of X509 peer certificate for verification.
1169 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1171 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1172 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1173 as "modular" but it simplifies things.
1175 Added cs_get_peer_certificate to that returns peer X509 PEM.
1177 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1178 NULL if SSL is unavailable.
1180 Documentation about MARC decoding tools.
1182 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1184 --- 2.0.19 2004/03/30
1186 Rename CHANGELOG to NEWS to follow GNU style packing.
1188 Fix bug with missing initialization of member in init_diagnostics.
1189 This bug affects threaded version of GFS server.
1191 --- 2.0.18 2004/03/20
1193 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1196 Ensure zlib.dll is packed with Windows install.
1198 --- 2.0.17 2004/03/17
1200 Fix encoding of xsd:string to use text instead of CDATA.
1202 Fix endless loop in CQL parser with unbalanced ".
1204 Use a more compact way to store MARC-8 conversion tables.
1206 --- 2.0.16 2004/03/16 Debian only
1208 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1211 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1216 --- 2.0.15 2004/03/01
1218 Another fix for decoding of XML packed records.
1220 --- 2.0.14 2004/02/25
1222 Fixes for Chunked encoding. White space not ignored after length spec.
1224 Update NS and use default NS for SRW diagnostic elements.
1226 --- 2.0.13 2004/02/23
1228 Implement ZOOM_resultset_cache_reset which resets record cache.
1230 Implement ZOOM_resultset_sort which sorts a result set.
1232 Implement chunked HTTP transfer.
1234 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1236 --- 2.0.12 2004/02/16
1238 Added member 'schema' to bend_explain_rr structure so that backend
1239 can specify explain record identifier. Defaults to Zeerex 2.0.
1241 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1243 --- 2.0.11 2004/02/16
1245 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1248 Added init command for yaz-client which sends "extra" init request.
1250 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1251 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1253 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1255 Make ZOOM error code for "invalid query".
1257 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1259 --- 2.0.10 2004/02/05
1261 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1264 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1266 Added option -p <file> to make Generic Frontend Server to write PID file.
1268 Added option -D to put Generic Frontend Server in background on its own.
1270 Make ZOOM C recognize option "password". If unset, "pass" is used
1271 (for backwards compatibility).
1273 Fixed a bug in Generic Frontend Server that could make it crash if a
1274 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1277 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1278 Must be issued before open, in order to be in effect.
1280 --- 2.0.9-6 2004/01/12 Debian/Windows
1282 Make the SRU server more picky WRT unknown params, etc.
1284 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1286 New YAZ client command, options, that sets Z39.50 options.
1288 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1289 options from a string of tokens (one token for each option bit).
1291 Update SRW diagnostic code messages.
1293 --- 2.0.9-5 2004/01/07 Debian/Windows
1295 Handle user defined stylesheet for SRW/SRU.
1297 --- 2.0.9-4 2004/01/06 Debian/Windows
1299 Fix bug in decoding of Content-Length.
1301 --- 2.0.9-3 2004/01/06 Debian/Windows
1303 Fix a bug with decoding of XML packed records.
1305 --- 2.0.9-2 2004/01/05 Debian only
1307 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1309 Fix bug in SRW/SRU diagnostics decoding.
1311 --- 2.0.9 2004/01/05
1313 Fixed bug in Generic Frontend Server which could drop records exceeding
1314 preferred message size. Reported and fixed by Irina Dijour.
1316 Fixed calculation of package size for structured records in Generic
1317 Frontend Server. Reported and fixed by Irina Dijour.
1319 Fixed namespace for SRW/SRU diagnostics.
1321 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1323 --- 2.0.8 2003/12/22
1325 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1326 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1329 CQL changes to reflect recent changes to the specification:
1330 * Documentation talks about context sets instead of index sets.
1331 * Documentation talks about indexes instead of qualifiers.
1332 * The CQL-to-PQF transformer's configuration file now uses
1333 "index.set.name = <attributes>" instead of the old form
1334 "qualifier.set.name = <attributes>". (Both forms are still
1335 understood but the latter is deprecated.)
1336 * CQL terms with no explicit index specified are now interpreted as
1337 cql.serverChoice instead of srw.serverChoice (which of course
1338 behaves exactly the same.)
1340 --- 2.0.7 2003/12/16
1342 MARC conversion can now generate ISO2709 output in another
1343 character set. yaz-marcdump uses this facility if you invoke it
1346 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1347 functions from there can be used from C++.
1349 --- 2.0.6 2003/12/04
1351 Frontend server now transfers memory from decoded packages to stream
1354 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1355 references to show up.
1357 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1358 the ZOOM Abstract API. The older names for the same options are still
1359 also supported for the benefit of old applications.
1361 ZOOM-C supports "implementationId" and "implementationVersion" options
1362 to go along with "implementationName". These allow the user code to
1363 specify identification strings to be sent to servers.
1364 Add OID for the new ExtLite attribute set.
1366 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1367 as requested/supplid by Ere Maijala <ere@atp.fi>
1369 For generic frontend server, reverse the order of
1370 "toolkit-supplied / application-supplied" strings sent as implementationId,
1371 Name and Version. Also, remove the spaces around the slash. This brings
1372 the GFS in line with the behaviour of ZOOM-C on the client side.
1374 Add function ZOOM_scanset_display_term.
1376 yaz-client shows scan displayTerm if present.
1378 Utility yaz-iconv is now installed by default along with the man page
1381 Extend configure check for OpenSSL to use pkg-config where available (such
1384 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1385 server to specify uid/gid/mask for socket using the format
1386 unix:[user=uid,][group=gid,][umask=mask,]file=path
1387 If file= is omitted the existing format is assumed, e.g.
1389 in which case the mask is 0666 (rw for everybody).
1391 Major restructure of YAZ source. All source in libyaz is in src directory.
1392 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1393 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1395 Added man page for utility yaz-marcdump (used to be called marcdump).
1396 yaz-marcdump is installed by 'make install'.
1398 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1399 of incoming package failed.
1401 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1403 Change prototype of odr_perror: add const to message string.
1405 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1407 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1408 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1409 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1410 DNS lookup. There should not be any compatibility problems with this
1411 assuming that blocking=1 or 0 is used.
1413 Fix bad reference in UNIX comstack in function cs_addrstr.
1415 Fix for compilation on AIX.
1417 The generic front-end server (server/seshigh.c) now supports returning
1418 Init diagnostics to the client in User-information-field, in
1419 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1422 --- 2.0.4 2003/09/04
1424 Allow any CQL relation (not just all,any,exact,scr).
1426 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1427 that features the same UI.
1429 Implemented command update0 in YAZ client which is equivalent to
1430 update but uses old of Ext Update ASN.1.
1432 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1433 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1434 Previously no OID was used for this info.
1436 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1437 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1438 returns 'malformed search term' otherwise.
1440 SortResponse member resultCount now set to NULL in sort handler of
1443 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1446 Add three new utility functions for translating OIDs between various
1447 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1448 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1449 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1450 char *oid_to_dotstring(const int *oid, char *oidbuf);
1451 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1453 Reverted modifications for ES Update definition for z_IU0Update
1454 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1455 is back to YAZ 2.0.2.
1457 String value attributes for CCL parser.
1459 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1460 which their FirstSearch server returns in Init responses, sometimes
1461 carrying useful diagnostic information when Init fails. This has the
1462 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1463 "z39.50/oclcui.asn", where its definition is somewhat different from
1464 what OCLC document on their web-site, as required to interoperate with
1467 Support for anonymous authentication in yaz-client. Use the command
1470 * Fix the OID of the Index Data-local "admin" Extended Service from
1471 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1472 the 1000, which indicates a locally-defined OID, was a mistake.
1474 --- 2.0.3 2003/06/20
1476 Fix CCL directive @case handling so that it affects string match for
1477 both CCL keywords and qualifiers.
1479 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1480 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1481 Decoder has been updated with ASN.1 changes as listed in
1482 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1483 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1484 z_IUUpdate, remains unchanged.
1486 ZOOM_record_get may now return a record in a specific character set.
1487 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1488 "from" is the character set of record as returned by target. "to" is
1489 the character set to be returned. If omitted, "to" is UTF-8.
1491 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1493 New ODR utility, odr_getelement, which returns name of element for
1494 which encoding/decoding failed.
1496 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1497 in cases where a required element was omitted.
1499 Bug fix: some MARC8 sequences were not converted.
1501 New ZOOM option "step" which specifies number of records to be
1502 retrieved in one chunk. Used in conjunction with "start" and "count".
1504 SRW support for yaz-client. Use scheme http: to use it, e.g.
1507 yaz-client no longer does (un)intelligent character set conversions
1508 by default. Can be enabled with charset and marc_charset commands.
1510 xmalloc trace fix for 64-bit systems such as DEC alpha.
1512 Solaris 2.6 compile fix.
1514 New function, cql_strerror() translates SRW error codes, as returned
1515 by cql_transform_error(), into human-readable English strings. Used
1516 in yaz-client diagnostics when appropriate.
1518 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1519 converts it into a type-1 query which is sent to the server. This
1520 makes CQL available for use with all Z-servers, as opposed to the tiny
1521 minority that can handle CQL queries themselves.
1523 --- 2.0.2 2003/04/28
1525 New Debian package layout similar to the Redhat Package layout.
1527 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1528 and search result respectively.
1530 --- 2.0.1 2003/04/25
1532 Redhat package is now several packages: libyaz (runtime libraries),
1533 libyaz-devel (development and documentation, and yaz (utility programs).
1534 Package spec file by Morten Bogeskov.
1536 New member 'schema' in struct bend_fetch_rr which the name of requested
1537 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1538 handler MAY set this to reflect the schema of the returned record.
1540 New member 'display_term' in struct scan_entry. GFS now sets member entries
1541 and allocates scan entries to be filled by user scan handler. In previous
1542 version, entries member was allocated by the scan handler. That still works,
1543 but the GFS will ignore member display_term - assuming it was NOT set by
1544 the handler. The fact that the GFS now allocates the entries both allows
1545 for new members and makes a scan handler easier to write.
1547 Fix CQL lex buffer overflow.
1549 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1550 SRU default recordPacking is string.
1552 SRU protocol support for frontend server.
1554 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1556 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1558 Added scan for the ZOOM shell (zoomsh).
1562 * String Identifers for Schemas (Amendment 5).
1563 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1564 Old definition for schema
1565 Odr_oid *schema; /* OPT */
1570 Z_InternationalString *uri;
1571 #define Z_Schema_oid 1
1572 #define Z_Schema_uri 2
1575 * resultCount parameter to Sort Response (Amendment 1).
1576 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1578 Support for SRW 1.0 over HTTP. This is an optional feature and
1579 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1582 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1583 on the same port. SRW SearchRetrieveRequests are mapped
1584 to bend_init,bend_search,bend_fetch,bend_close.
1586 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1588 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1589 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1591 ZOOM connections are SRW based if schem http is used for hostname
1592 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1593 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1595 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1596 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1597 distance=n, order=true/false, relation=le, prox unit=word. If
1598 n is omitted, distance 1 is used.
1600 Fixed problem with C compiler include path in wrong order.
1602 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1603 on Solaris. Patch from Ko van der Sloot.
1605 New MARC decode API. All new functions operate on a yaz_marc_t
1606 handle. The most important new functions are: yaz_marc_create,
1607 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1608 decode and destroy respectively. Decoder can produce formats
1609 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1610 include/yaz/marcdisp.h.
1612 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1613 to UTF-8, UCS-32, wchar_t or Latin-1.
1615 * Prototypes for yaz_iconv_-functions moved to separate header
1616 include/yaz/yaz-iconv.h.
1618 Make a few private functions 'static' in unix.c. This prevents
1619 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1621 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1622 are set when Init Response is received.
1624 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1625 but returns diagnostic set as well.
1627 New function yaz_strerror which is a portable wrapper for
1628 strerror/strerror_r/GetLastMessage.
1630 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1631 is returned for MARC. If type is "oai", then OAI MARC is returned.
1633 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1636 --- 1.9.2 2002/11/26
1638 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1640 Fix bad race conditions on SIGTERM and terminate gracefully in
1643 Move retrieval (data1) module to Zebra since nobody seems to be
1646 Add GRS-1 render for ZOOM using same format as yaz-client.
1648 --- 1.9.1 2002/10/05
1650 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1652 Fix broken ESpec handling in data1 module.
1654 SGML reader parses comments and makes them part of the data1 tree.
1656 Added several type casts so that YAZ compiles as C++ code.
1658 ZOOM didn't handle PDU encoding failures properly.
1660 Added more Bib-1 diagnostics (approved extensions).
1662 GNU configure: better check for iconv.
1664 More portable use of accept, getpeername. Check for socklen_t. Use
1665 int/size_t if socklen_t is not defined.
1669 PQF parser rejects bad queries - including those with extra
1670 characters in them. PQF parser used to silently ignore that.
1671 Cleaner API for PQF added, which allows you to get detailed
1672 error information for bad queries (see yaz/pquery.h).
1674 Fixed bug in ZOOM_record_get for type "database".
1676 Implemented mini iconv library supporting conversions between
1677 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1679 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1681 --- 1.8.9 2002/08/20
1683 Fixed ZOOM C record cache so that preferredRecordSyntax and
1684 elementSetName is used to check for already fetched records.
1686 --- 1.8.8 2002/08/02
1688 Added three members in bend_initrequest structure to facilitate
1689 character set negotiation.
1691 Fixed a bug in frontend server that could cause indefinite
1692 loops under rare conditions.
1694 Revised character set utilities (charneg.h) so that encoding
1695 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1697 For PQF, directive @term <type> sets term type for Scan/Search.
1698 Here <type> is general, string, numeric, null. The term type
1699 is inherited - just like @attr.
1701 New call odr_set_charset that sets character set conversion for
1702 international-strings on a ODR stream. Prototype is:
1703 int odr_set_charset(ODR o, const char *to, const char *from);
1704 The InternationalString is still represented as C string in YAZ
1705 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1706 won't). On the protocol level, you can use any encoding.
1708 Support for UNIX sockets in ZOOM.
1710 Solaris recv sometimes returns errno == ENOENT. It is treated as
1711 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1713 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1714 both client and server. Code by Morten Bogeskov.
1716 --- 1.8.7 2002/05/22
1718 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1719 that they can be used directly from Visual Basic. You must recompile
1720 your windows APP if you're using ZOOM.
1722 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1723 Commands "lang" and "charset" sets language and character set respectively.
1724 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1725 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1727 Attributes from multiple CCL fields may be OR'ed rather than merged
1728 using directive "@field or". Fields are still merged by default -
1729 equivalent to "@field merge".
1731 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1734 Fixed bug in zget for parameter ExtendedServicesResponse.
1738 --- 1.8.6 2002/03/25
1740 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1742 Client displays USR.1:SearchResult-1 (hits per term).
1744 Additional Search Info for search in Generic Frontend Server.
1746 Fixed CCL parsing of "field=s".
1748 WIN32 installer - using the excellent NSIS software from nullsoft.
1750 Fixed CCL parsing of "field = - <number>".
1752 Added function yaz_marc_decode that decodes MARC for line mode
1753 display or XML (similar to that used by JZKit).
1755 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1756 Z39.50. But ISO/ILL was, however.
1758 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1759 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1761 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1762 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1764 --- 1.8.5 2002/02/03
1766 New YAZ client features: Command completion and new commands:
1767 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1768 Code provided by Jacob Poulsen.
1770 New call oid_trav, that visits all registered OIDs via callback.
1772 Function ZOOM_record_get now returns const char pointer rather than
1773 void pointer. It saves a lot of type casts.
1775 For YAZ client, command "auth" now allows you to set authentication
1776 in IdPass style. It is enabled when three tokens are given - order
1777 is user, group and password.
1779 Fix memory leaks in MARC record handling for ZOOM.
1781 New option for YAZ client, -k <kilobytes> that sets
1782 maximum record size. Similar to -k option for generic frontend
1783 server and yaz-ztest.
1785 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1787 Prefix query parser reports "fail" when bad attribute set is given.
1789 Fix in MARC decoder. Proximity logging. Fix for attribute set
1790 in scan handler for server. Patches by Shigeru Ishida.
1792 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1795 Configure option --with-openssl=<dir> now works when a directory is
1796 specified. Patch provided by Morten Bogeskov.
1798 New option for YAZ client, -u <auth>, that sets authentication.
1800 ZOOM fix: error information was sometimes "missing", since error
1801 was cleared/reset too when it shouldn't.
1803 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1805 --- 1.8.4 2002/01/04
1807 Scan for ZOOM API. New object ZOOM_scanset. New functions
1808 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1809 ZOOM_scanset_destroy.
1811 New ZOOM function, ZOOM_connection_last_event, that returns type
1812 of last event (such as "receive data", "send data", "apdu received",
1815 New ZOOM option, schema, that specifies schema for retrieval.
1817 New CCL feature. Qualifiers can be aliases for one or more
1818 other qualifiers (if more than one is given, OR is used).
1820 ZOOM uses named result sets if target supports it.
1822 Two new YAZ client commands: . (dot, which sources a script of YAZ
1823 client commands), and ! (to execute shell command.). Implemented
1826 Working on Debian packages.
1828 --- 1.8.3 2001/11/19
1830 YAZ client enables named result sets only if target supports it.
1832 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1834 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1835 with key="host" to get same result.
1837 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1838 Function Z3950_resultset_record(s) returns references to records
1839 "owned" by resultset. To become owner use Z3950_record_clone.
1841 Function z_ext_record handles Extended Services. Thanks to
1844 --- 1.8.2 2001/11/12
1846 CCL Parser fix: ignore token comma when dealing with and-lists.
1848 Documentation updates for COMSTACK.
1850 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1851 Changed prototype Z3950_records. For some functions, int parameters
1852 were changed to size_t.
1854 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1857 New MARC decode/display function, marc_display_exl, which properly rejects
1858 non-ISO2709 records. YAZ client uses it.
1860 --- 1.8.1 2001/10/29
1862 Fix bug: local attribute set wasn't set correctly in PQF strings.
1866 * Old Z39.50 codecs no longer supported.
1868 Added ZOOM C binding. See http://zoom.z3950.org/
1870 Renamed states for COMSTACKs to avoid confusion with events.
1872 Implemented cs_look and proper cs_rcvconnect.
1874 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1876 Configure detects POSIX threads on OpenBSD.
1878 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1879 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1881 When error is returned from present handler, non-surrogate diagnostic
1882 is returned in present response (and fetch handler is no longer called).
1884 * Minor adjustments to pquery parser (PQF). Token characters may be
1885 escaped by using backslash (C-style).
1887 PQF parser allows string attribute values to be specified. For @attr,
1888 non-numeric characters after the equal-sign are treated as strings
1889 (e.g. @attr 9=title).
1891 CCL trunction character may be defined (@truncation in file)
1893 * function zget_ExtendedServicesRequest sets waitAction to
1894 waitIfPossible (was wait).
1896 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1899 CCL operator names may be set in field definition files (CCL_bibset).
1900 See ccl/bib1 for an example.
1902 Fixes in ASN.1 compiler for C++ compatibility.
1904 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1905 and "op_or" to avoid conflict with C++.
1907 Fixed problem with GNU readline detection on Redhat 7.0.
1909 Added step-size for Scan backend handler.
1911 Fixed bug that made the frontend server crash when no attribute
1912 set was specified for scan.
1914 Front-end server automatically switches to original working directory
1915 when installed as an NT service. Previously -w had to be specified to
1918 Added extended attributes for retrieval module (data1), so that data1
1919 records carry d1_readXML/SGML attributes. d1_read also supports
1920 null-data rules ( <tag/>)
1922 On UNIX when POSIX threads are available, a separate library libyazthread
1923 is created. Programmers should link with that library and the yaz library
1924 when using threads. The reason for the split was that some applications
1925 on Linux, such as Apache, doesn't work well when using shared objects that
1928 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1929 (or any frontend server) in SSL mode by specifying ssl: followed by
1930 address. Only tested on UNIX.
1932 Added feature for CCL module. Virtual structure s=al or s=ol generates
1933 and-list and or-list respectively instead of phrase search.
1937 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1938 log_mask_str. This was done to avoid name conflicts with other libraries
1939 (such as other PHP extensions).
1941 Added raw OID member for preferred record syntax (request_format_raw)
1942 and returned record syntax (output_format_raw) for backend fetch method.
1944 Config file yaz-config now accepts options so that it returns specific
1945 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1947 Shared library support for UNIX using GNU libtool.
1949 * Modified backend interface. Request/Response struct's replaced by
1950 one read/write C struct. For example bend_fetchrequest and
1951 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1952 Every handler - even search has to be registered in bend_init
1953 handler. This means that the YAZ library no longer refers to
1954 external functions and it makes it possible to make the whole
1955 thing a single DLL/SO.
1957 Added Segment handler for backend server.
1959 Added Zmbol/Zebra administrative functions to YAZ client.
1961 Threaded frontend server on UNIX (when POSIX Threads are available).
1962 Starting the server with option -T enables multi-threading.
1966 Added configure option --enable-comp/disable-comp to control use
1967 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1968 located in sub directory asn.
1970 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1971 in ${exec_prefix}/bin along with the other programs yaz-client and
1974 GNU automake used to maintain makefiles.
1976 Added several OID's.
1978 Changed retrieval module so that we can load records with no abstract
1979 syntax defined. Tagpaths in these records are fully composed of string
1982 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1986 On UNIX, the generated makefile now supports a proper 'make install'.
1987 The prefix can be set via GNU configure to set the install location
1988 (default is /usr/local).
1990 * YAZ programs client and ztest were renamed to yaz-client and
1991 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1992 locations, such as /usr/bin,/usr/local/bin,etc.
1994 * YAZ Header files were moved from include to include/yaz. YAZ Header
1995 files are referred to as include <yaz/log.h> rather than <log.h>.
1996 The YAZ include path (-I ..) is therefore the same as before. Programmers
1997 should update their #include statements or use -Ipath/include/yaz
1998 instead. The main motivation for doing this change is that YAZ header files
1999 can be installed in "standard" locations /usr/include,/usr/local/include
2000 without introducing conflicts, since ALL YAZ header files are stored
2001 in subdirectory yaz (under /usr/include for example).
2003 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2004 rather than project/workspace files. We switched because project files
2005 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2008 Changed name of logging function, logf, to yaz_log, to prevent name
2009 clash with some math-log functions. The YAZ header log.h defines logf
2010 to yaz_log (#define) so there should be no incompatibilities by this
2013 Added bend_start/bend_stop handlers for server. These handler are
2014 called on start/stop of server. For windows they are called whenever
2015 a service is started/stopped.
2017 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2018 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2019 in util/yc.tcl. The auto-generated C code structures are, in a few
2020 cases, incompatible with the old decoders. There are differences in the
2021 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2022 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2023 The preprocessor variable ASN_COMPILED is defined when the compiled
2024 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2025 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2026 wish to use the old encoders/decoders you can specify --disable-yc
2029 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2030 version so that it supports both new - and old version of DB Update
2032 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2033 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2034 change. The name parameter can be set to 0 in which no name is specified
2035 for the construction. The macros odr_implicit and odr_explicit sets name
2036 parameter to zero for the construction involved. New macros
2037 odr_implicit_tag and odr_explicit_tag are similar to the others,
2038 except that a name parameter is added. For programmers' that don't use
2039 ODR they probably only need to change the call to z_APDU and z_External.
2041 Added access control facility by interfacing the TCP wrapper library.
2042 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2043 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2044 name of the daemon and enables the access control as specified in
2045 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2047 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2048 den Dool <H.M.vdnDool@kub.nl>.
2050 Added reference ID parameter to most functions in server API - refer
2051 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2053 Changed name of ccl library to libccl.a (was ccl.a).
2055 Fixed bug in decoder for Explain (Category TargetInfo).
2057 Added support for GNU readline in client. Thanks to Jacob Poulsen
2058 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2060 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2061 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2062 IMPLEMENTATION! This change was made to the development version before
2063 the ZIG decided to retract the amendment. If any users MUST be
2064 compatible with the original Update definition, PLEASE CONTACT US, and
2065 we will include a separate definition corresponding to the old Update
2066 ES. Note that because of the change to the ASN.1 of the
2067 TaskPackageRecordStructure we cannot define a single structure that
2068 will support both versions.
2070 * Added const modifier to buffer parameter for some ODR/BER encoding
2071 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2072 completeWAIS, odr_dumpBER.
2074 Fixed bug in client.c which caused a crash when a scanResponse didn't
2075 contain positionOfTerm.
2077 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2078 * will cause an error in a client if a non-YAZ target sends both a
2079 * list of Scan entries and non-surrogate diagnostics.
2081 Retrieval module enhancements. Tag sets may be typed in the reference
2082 to it. From the .abs-file the "tagset" directive takes a third optional
2083 integer type for the tag set referenced. From a .tag-file the "include"
2084 directive takes a third optional type as well. The old "type" directive
2085 in the tag set itself is still recognized but acts as the default type
2088 Backend interface change. Individual Scan terms returned from bend_scan
2089 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2090 in include/backend.h.
2092 Retrieval module enhancements. Multiple tag sets and attribute sets may
2093 be specified in abstract syntax specs. Revised the error/warning for
2094 logging messages reported by the retrieval module when reading the
2097 Object Identifier system (oid_..) changed. The API is backwards
2098 compatible but the oid-routines now allocates new OID's when needed.
2099 Raw OID's may be specified in oid_getvalbyname.
2101 YAZ now uses GNU configure to generate Makefile(s).
2103 * Minor changes in some of the member names of DeleteResultSetRequest and
2104 DeleteResultSetResponse. See include/proto.h.
2106 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2107 and added member 'languages' in TargetInfo (which was missing).
2109 Changed the way attribute sets are handled in the retrieval
2110 module. These are now cached, just like the abstract syntaxes
2113 Changed YAZ so that it links with compiled ASN.1.
2115 Added Explain-schema definitions and mapping routines. The following
2116 Explain categories have been implemented: AttributeDetails,
2117 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2119 Fixed minor bug in Windows version of Server Library.
2121 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2123 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2125 Added EXTERNAL: UNIverse Resource Report (non-standard).
2127 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2128 ENUMERATED and SET OF.
2130 * Added 'const' to some of the char pointer arguments for the
2131 functions, data1_read_node, data1_getelementbytagname,
2132 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2135 Fixed bug in data1_insert_taggeddata - the last_child member of
2136 parent wasn't initialised.
2138 * Changed data1_read_record and data1_read_node so that the supplied
2139 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2140 doesn't refer to any parts of the "SGML"-buffer.
2142 Fixed bug in server library (Windows version of statserv_remove).
2144 * Changed code so that it compiles as C++. The type definition
2145 of Odr_fun which is a member of Odr_arm was changed. The result is,
2146 that an explicit typecast is needed for the fun pointer when
2147 using Odr_arm - as in:
2148 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2150 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2152 Implemented the new structured date and time definition as approved
2153 by the ZIG. Added schemaId element to the specificTag in Espec-1
2154 (also approved at the last ZIG). Thanks to RVDM.
2156 Added some Object identifiers (RVDM).
2158 Changed the Update Extended Service (RVDM).
2160 Added command "refid" to client which specifies referenceId for
2161 the following requests.
2163 Implemented extended service handling for server. See ztest.c
2164 for an example as well as backend.h. New handlers are registerd
2165 in the Init handler.
2167 * Changed interface for sort in server.
2169 Added new members to statserv_options_block. It allows a server
2170 to read options from another source than just the command line. Thanks
2171 to Charles Woodfield.
2173 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2174 renamed to zboolean. Some C++ compilers complained about the name.
2176 Minor changes to gils.abs. Added index 's' (sort) on title
2177 and date/time-last-modified.
2179 --- 1.4pl2 1998/1/30
2181 Fixed bug in server library regarding inetd mode (-i). This bug
2182 was introduced by release 1.4.
2184 --- 1.4pl1 1998/1/29
2186 Added sort facility in client and backend server interface.
2188 Fixed problem with dependencies in Makefile(s).
2190 Fixed bugs for encoders/decoders of extended services and
2193 Implemented sub-tree feature for schemas. Sub-trees are
2194 referenced in *.abs-files. See explain.abs for an example
2195 of the use of this feature.
2197 Modified bib1.att; local attributes for ANY didn't include
2198 ANY itself (only affects use of the retrieval module).
2200 Fixed bug in plain SGML reader in function data1_read_node:
2201 tags with prefix "var" was incorrectly interpreted as variants.
2203 Added feature "sub-schemas" to enable references to - and definitions
2204 of - group of elements.
2206 * Removed member parent from type data1_element (in data1.h).
2208 Implemented function odr_nullval() that returns the value of
2211 * Removed member num_children from data1_node (in data1.h).
2213 Made NT service interface part of the server library. The
2214 function statserv_main uses the NT service when required and
2215 calls the statserv_start / statserv_close routines.
2217 Routine zget_SearchRequest and zget_PresentRequest fills
2218 resultSetName/Id member with "default" instead of "Default".
2220 Fixed memory leak in server. Request queue member wasn't freed.
2222 Fixed nmem_exit so that memory is freed.
2226 Revised the CCL parser utility to be thread safe.
2228 Added function, oid_ent_to_oid, to replace the function
2229 oid_getoidbyent, which is not thread safe.
2231 * Added nmem_init and nmem_exit to initialize and release
2232 NMEM resources. Function nmem_init should be called once in the
2233 initial thread before NMEM/ODR is used. statserv.c and client.c
2234 have been changed accordingly. The change was necessary to make
2235 NMEM thread safe. The NMEM memory pool is shared amongst threads
2236 in a process. Unix-based applications will still work fine without
2239 Added NT Services interface for the the Z39.50 (statserv) Server.
2240 Refer to the ztest.c source on the usage.
2242 Windows 95/NT port using MSVC5.0. Project files are included in the
2245 * Defined new 'global' handle for the retrieval (data1) system. The
2246 new handled, data1_handle, describes the state of the data1 system.
2247 This handle is passed as first argument to virtually all
2248 data1 related routines. The functions data1_create and data1_destroy
2249 creates and destroys a data1 handle respectively.
2251 Added ODR encode stream member to all backend request structures
2252 init, search, scan etc. This stream should be used to allocate all
2253 memory used for the response when thread safe operation is needed.
2255 Changed the comstack utility, cs_addstr, to be thread safe. The
2256 returned hostname string returned by the function is now part the
2259 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2260 function. The cs_straddr takes a COMSTACK handle as argument, so this
2261 function must be used after cs_create and before bind/connect.
2262 This function is thread safe.
2264 Moved test server to 'ztest' directory - generic server code still
2265 in 'server' directory.
2267 Made prefix query (pquery.c) utility thread safe.
2269 Added new function modifier YAZ_EXPORT to 'export' public DLL
2270 functions when using windows (see include/yconfig.h).
2272 Added definitions to the OID database (util/oid.c) (RVDM).
2274 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2276 Added call to ccl_rpn_delete in client program.
2278 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2279 release of RPN structure.
2281 Added support for C++, headers uses extern "C" for public definitions.
2282 With input from RVDM.
2284 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2285 Thanks to Ronald van der Meer (RVDM).
2287 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2289 Added support for private extensions to the OID database
2290 (oid_setprivateoids()). Thanks to RVDM.
2292 Added optional, physical ANY (key replication)
2294 Fixed null-reference problem in GRS-1 output filter.
2296 Proximity operator added to Prefix Query Format (PQF).
2298 In test client command "base" accepts multiple databases.
2300 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2304 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2306 Smallish bug-fixes in the new encoders/decoders (explain).
2308 Bug fixed in DeleteRequest.
2310 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2312 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2314 Added SOIF syntax (using private OID for now) to retrieval module and client.
2316 Added Update extended service.
2318 Added SearchResult-1 additional info structure.
2320 Added optional CCL (ISO8777) interpreter as separate module. Available
2323 --- 1.2 1996/6/10 (1st anniversary release)
2325 Added Summary record syntax. Lightly tested.
2327 Added OPAC record syntax. Untested.
2329 Added ResourceReport service encoders/decoders. Untested.
2331 Fixed bug in z_Unit - wrong tagging on unitSystem.
2333 Fixed bug in the DiagRecs decoder.
2335 Added options for max PDU size and session timeout to frontend-server.
2337 Added documentation of query-language parsers and other supporting utilities.
2339 [frontend-server] Added Attribute set to the bend_scanrequest API.
2341 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2342 surrogate diagnostics were generated.
2344 [retrieval] Allow multiple local values for attribute.
2346 [retrieval] Allow multiple attributes per element in .abs files. index type.
2348 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2350 --- 1.1pl2 1996/4/10
2352 Minor changes, mostly specific to Zebra's requirements (retrieval)
2356 Repaired bug in frontend server when running multiple listening
2357 endpoints in dynamic mode.
2359 z_External() now won't break if a known, ASN.1 value comes encapsulated
2360 in an octet-string. The value will pass through unmodified in an Odr_oct.
2362 Added a bit of code to the demo client to decode & display
2363 ASN.1-structured records represented in the octet-aligned branch of
2364 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2366 Added z_ext_getentbyref() to the ASN module. Doc updated.
2368 * Completed the SCAN definition in the ASN module. This may break SCAN
2369 code based on older YAZ-versions at compile-time. The fix is easy -
2372 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2373 under the SCAN definition. Remember to initialize this, server-people.
2375 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2376 that this does not extend to ODR and ASN.
2378 Comstack allows insertion of established socket (primarily for
2379 inetd-operation of servers). Doc updated.
2381 Front-end server can now start from the inetd in TCP mode. Doc
2384 --- 1.0pl4 1996/1/24
2388 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2389 the rank and record number.
2391 Adjustments to the frontend server.
2393 Fixed diagnostic BER dumper. It ignored the file argument.
2397 Various changes to retrieval module.
2399 Changed the union discriminators of the protocol files from enums to
2400 ints paired with #defines.
2402 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2405 *Changed operator in the RPN structure to 'roperator', again to avoid a
2408 Fixed problems in Explain decoders/encoders.
2410 --- 1.0pl2 1995/12/6
2412 Memory bug in log module fixed.
2414 --- 1.0pl1 1995/12/5
2416 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2418 Bug in Explain DatabaseInfo module fixed.
2420 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2424 The shift to v1.0 signals that we now consider the *core* functionality
2425 of YAZ reasonably stable (the core being more or less equivalent to
2426 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2427 tested (Explain not at all - though that will happen soonish).
2429 Minor changes to code to support Windows port.
2431 Various minor changes after we're getting to use GRS-1 & co. more.
2433 Added Espec-1 format.
2435 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2436 of the protocol and it cannot be selected when encoding (maps into 'string'
2437 when decoding). Needed to talk to some servers.
2439 Demo client can request simple element set names.
2441 Added Diagnostic Format encoders/decoders.
2443 Added simple Close handling to frontend server (no hooks for resource
2444 reporting yet), and demonstration client.
2446 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2448 --- 1.0b3 1995/08/24
2450 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2451 handled incorrectly when records were requested in the searchResponse. This
2452 will only affect you if you use the frontend-server.
2454 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2455 Test-client will ask for and print GRS1. Ztest will return dummy records
2458 Added Explain encoders/decoders to the service-level API. Untested.
2460 Added Extended Services: Item Order encoders and decoders to the Service-
2461 level API. Untested. We could use a recent copy of the pertinent bits
2462 of the ILL protocol to add those bits.
2464 Added diagnostic format 1 encoders/decoders to the service-level API.
2467 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2468 odr_cons.c, which causes a more correct output.
2470 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2471 was always set to 0 when no records were requested in the searchRequest.
2473 * Added better external-handling. This shouldn't harm old code that
2474 *encodes* externals. It can break code that looks for a
2475 'single-ASN1-type' representation, since those types that are known
2476 are now decoded immediately. Look at the SUTRS sample code in
2477 seshigh.c and client.c. Documentation updated.
2479 Handling of structured records in bend_fetchresponse. Length -1 marks
2480 structured record, type is deduced from format field.
2482 --- 1.0b2 1995/06/27
2483 Fairly quick maintenance release to add SUTRS support.
2485 Fixed handling of SUTRS records in the demonstration client.
2487 * Added format field to the bend_fetchrequest and bend_fetchresponce
2488 structures of the backend API (frontend server). When the record is
2489 returned, the value of the format field is mapped to an OID. The
2490 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
