1 Added member named_result_sets for init handler struct for the GFS. This
2 allows a server to disable named result sets.
6 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
10 For configure, using option --without-xml2 also disables Libxslt/Libexslt
13 Fixed bug #2352: yaz-marcdump crashes for certain record.
15 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
17 Added support for Danmarc2 to UTF-8 conversion.
19 Added support for ISO5426 to UTF-8 conversion.
21 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
22 implementation version.
24 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
28 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
29 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
31 ZOOM C now interprets databaseName option for ZOOM connection as path
34 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
36 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
38 Dummy Libxml2 types no longer defined in headers of YAZ'.
40 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
45 Various ODR chapter fixes.
47 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
49 Added missing source for Windows compilation, mutex.c.
51 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
53 For SRU connections in ZOOM all records up to "count" are now fetched.
55 Fixed crash in generic frontend server (and yaz-ztest) which occurred
56 in Windows due to bad error handling for Libxml2.
58 Added facility for sending arbitrary records (ASN.1 any) using
59 ZOOM C's Extended service update. Patch by Sam Reynolds.
61 New options for ZOOM C's connection, logapdu which makes ZOOM log
66 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
70 Fixed memory violation that could occur when decoding UTF-8. This bug
71 was only present in 3.0.30 of YAZ.
75 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
76 GNU TLS is used by default (if found).
78 yaz-ztest returns OPAC records if a client asks for OPAC.
80 Improved speed of MARC-8 encoding.
82 Added support for lossy and loss-less MARC-8 encoding.
84 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
86 Added new Windows Service wrapper (sc).
88 yaz-client's itemorder command may now send a file.
90 Fixed yaz-marcdump to allow the use of NS prefix for record element.
92 Added new function yaz_log_xml_errors.
94 Allow (but warn) unknown XML attributes in MARCXML parsing.
96 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
98 The UTF-8 to MARC-8 conversion now uses a different set of characters
99 for Greek symbols. Bug #2120.
101 --- 3.0.26 2008/02/21
103 Added yaz_daemon (daemon.h).
105 Fixed bug #2068: pkg-config trouble
107 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
109 --- 3.0.24 2008/01/28
111 Document --with-xml2 option.
113 Added OPAC XML XSD (etc/opacxml.xsd).
115 Allow glob mask for name attribute in retrieval element for the
116 generic frontend server's retrieval facility.
118 Changed yaz_poll_poll to return yaz_poll_except for all returned events
119 except POLLIN/POLLOUT.
121 Fixed error handling in cs_listen. Bug #2037.
123 --- 3.0.22 2008/01/20
125 Fixed version in yaz/yaz-version.h.
127 Fixed bug #2027: Crash when closing connection.
129 Changed configure so that ICU support is only enabled if only ICU
130 and Libxml2 is available (because the ICU chain is XML based).
132 --- 3.0.20 2008/01/15
134 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
135 is built. Only this DLL depends on the ICU runtime.
137 yaz-ziffy is no longer part of YAZ. It is distributed separately by
138 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
140 Changed license of CCL module to 'Revised BSD'. After consultation with
141 remaining members of the original EUROPAGATE consortium, we are re-issuing
142 the CCL module without a separate license. The software was developed by
143 Index Data as part of a research project. The special license was included
144 to help feed usage information back to the project consortium to support
145 project evaluation. At this time, the project consortium has long-since
146 disbanded, and the majority of the original principals have retired. At the
147 same time, we have significantly modified the software during the following
148 years, to the point where very practically no original code remains. To
149 simplify re-use of the software, we have contacted those members of the
150 consortium who could be reached, and agreed to re-issue the module as a
151 proper part of the YAZ package.
153 Tcl scripts uses /usr/bin/tclsh as preferred shell.
155 CQL closer to being version 1.2 compliant. CQL also allows free-form
156 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
159 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
160 bug could make Extended services handling crash in the ZOOM layer. This
161 bug was only present in YAZ 3.0.18.
163 --- 3.0.18 2007/12/19
165 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
168 yaz-marcdump reads and writes collection wrapped records.
170 Handle OPAC for record conversion module.
172 Fixes for ICU wrapper.
174 Allow ICU libs to be controlled with --with-icu .
176 --- 3.0.16 2007/11/12
178 Added yaz_poll which is a wrapper for select/poll. When poll is available
179 and non-buggy, it is used, by yaz_poll . This allows more than 1024
180 sockets to be in use.
182 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
183 functionality through an XML based configuration (ICU chain). This system
184 is useful for search facilities such as Pazpar2 and Zebra that needs to
185 perform tokenization of indexed material. The ICU code in a separate
186 library libyaz3_icu.a.
188 Added HTTP tunnel facility for COMSTACK, bug #1752.
189 This is a facility that allows a Web proxy, such as squid, to tunnel
190 Z39.50 traffic. This facility is "transparent" to must applications
191 using YAZ. It's enabled by using pseudo transport connect: followed by
192 the proxy address, followed by command, then follwed by he regular
193 "virtual" addresss. For example,
194 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
196 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
198 --- 3.0.14 2007/09/21
200 Fixed bad memory reference in ZOOM_record - cuased by member not being
201 initialized. This was a problem only in YAZ 3.0.12.
203 Fixed bug in conversion from MARC to XML: Non-XML characters in control
204 fields were not removed.
206 Changed the way C code is generated from codetables.xml. Made a MARC-8
207 conversion trie for each characterSet section rather than codeTable.
208 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
209 of codetables.xml from Larry Dixson, LOC. Bug #1464.
211 --- 3.0.12 2007/09/12
213 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
214 from ZOOM_record_error).
216 ZOOM C function ZOOM_record_get returns record schema for type="schema".
218 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
220 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
222 Better SRW-to-Bib-1 diagnostic mapping.
224 ZOOM C and yaz-client announces SRU version 1.2 by default.
226 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
229 Fixed in yaz_sru_decode to allow other version than 1.1.
231 --- 3.0.10 2007/08/22
233 Added support for SRU scan for ZOOM.
235 Added support for the use of the older versions or Extended Service
236 Update in ZOOM. To faciliate this, an option "updateVersion" may be
237 set to the version , 1=first, 2=second, 3=third. The third version is
238 what ZOOM C has used so far. And that, obviously, is the default.
240 Added support for CCL queries in Z39.50 queries sent to the GFS (and
241 therefore in Zebra and in SimpleServer-based applications). The new
242 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
243 qualifier file used to transform incoming CCL queries into Type-1 RPN,
244 which is passed into the back-end search callback function.
246 Added support for HTTP Basic authentication in clients: the SRU/W
247 codec encodes the username/password elements of the PDU structure
248 appropriately, and these may be set using the "user" and "password"
249 options in ZOOM-C applications (the same options that are used for
250 Z39.50 authentication).
254 Fixed bug #1208: SSL appears to be broken in ZOOM.
256 Fixed bug #1206: Libxml2 include path weirdness.
258 Added oid_name_to_dotstring.
260 Allow elementSetName to be specified for ZOOM C record update.
262 Allow waitAction to be specified for ZOOM C based for Extended Services.
264 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
265 syntax OID. Bug introduced in YAZ 3 series.
267 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
271 Fixed bug #1157: yaz-client does not read .yazclientrc from current
272 directory. yaz-client now reads commands from file given by option -f
273 if specified; then tries to read .yazclientrc in current directory.
274 Failing that, it reads .yazclientrc from user's home directory.
276 Added support for correlationInfo Note and ID for Record Update via
279 Added yaz-client command querycharset which specifies character set for
280 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
281 (termListAndStartPoint).
283 Charset ISO5428:1984 is an alias for ISO5428-1984.
285 Implemented a way to perform scan in a result set using Z39.50. This
286 is achieved by attaching the result set name in the characterInfo
287 (type InternationalString) of OtherInformation in the Scan Request PDU.
288 The result set is identified in the otherinformation by the new OID:
289 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
290 This allows for scan in result set and faceted search . Zebra did some
291 of this in the APT term using attribute type 8 and value being result
292 set. Using the OtherInformation approach for this is cleaner and easier
293 to work with in proxies and the like. This facility can be used in
294 yaz-client using new command setscan which takes a result set as first
295 argument, start position (APT) as second.
297 Changed decoding of SRU XML packed records to deal with servers that
298 have recordData with XML data with multiple root nodes. Also make
299 comparison for recordPacking case insensitive. Again, one server
300 returns "XML" where others return "xml".
302 For SRU responses allow Content-Type application/xml as well as text/xml.
306 Fixed bug in character set conversion of BER strings. Bug introduced
311 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
313 For OID class, use oid_class consistently.
315 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
318 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
319 character set for bibliographic information interchange". By Giannis Kosmas.
321 Added documentation on new OID API.
325 Changes to generic frontend server interface: added new member
326 'query_charset' for bend_initrequest structure. A backend init handler
327 should set this member to its native character set for query terms.
328 When defined, the frontend server logic will announce this character set
329 to a client if the negotiationModel bit is set by the client. All server
330 implementors are encouraged to specify this. If a backend server does not
331 specify this a warning is issued using yaz_log(YLOG_WARN,..).
333 Added CCL utility to remove terms (stop words) from resulting RPN
334 tree. This is handled by functions with prefix ccl_stop_words_ .
336 New ZOOM C option, "rpnCharset", which allows client-side conversion of
337 terms in RPN queries.
339 Clean-up the CCL API. Moved some internal structures from ccl.h to
340 private header cclp.h. Changed ccl_parser_create so that a Bibset must
341 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
342 This is replaced by ccl_parser_find_str which takes a string instead.
344 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
345 libyaz.la is the core of YAZ except the generic frontend server and
346 does not depend on POSIX threads anymore. libyaz_server.la is the
347 generic frontend server facilities and uses POSIX thread functionality
348 if available. The libyaz.la no longer depends on POSIX threads because
349 the number of global structures is limited. NMEM no longer re-uses blocks
350 between threads ; it simply free's memory immediately but allocates in
351 "large" chunks as usual. We don't expect any performance penalties
352 because of this. The yaz_log system is still using a global log_level so
353 caution must be taken when modifying it with yaz_log_init_.. +
354 yaz_log_mask_str. This, however, should not cause any trouble because
355 these functions are called during initialization of application code
356 anyway. `yaz-config --libs server` returns libs for server applications;
357 `yaz-config --libs` returns libs for non-server applications.
359 New OID database - with public definitions in oid_db.h. Removed old OID
360 database including the head oid.h and definitions such as enum oid_value
361 and struct oident. The new OID database uses the same string names as
362 before but the 'protocol' is gone. There are now only two representations
363 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
364 converts from string to OID; functions with prefix yaz_oid_to_string
365 converts the other way.
367 Change to emit_term() in CQL-to-PQF query translation: when a term has
368 the /regexp relation modifier, do not process it for leading and
369 trailing "^" and "*", which have quite different meanings in regular
372 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
373 write handlers no longer carries a 'last' parameter. This will make
374 yaz_iconv flush "less" characters. A flush is performed by call to
375 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
377 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
378 removed, because function yaz_query_to_wrbuf does the same.
380 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
381 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
383 Deprecated MARC utility functions removed.
385 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
388 Branch split: YAZ_2_1_55_branch
390 --- 2.1.54 2007/03/16
392 Fix to ZOOM-C so that transparent reconnection is properly handled on
393 connections that are in asynchronous mode.
395 Fixed compilation on OpenBSD 4.0.
397 Large strings in GRS-1 records are now properly displayed in yaz-client.
399 Added character conversion support for "advancegreek"; based on patch from
402 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
403 sequence is met. Before the error was not set so it would be unknown.
405 Adjust yaz-marcdump MARC reader so that it skips until record separator
408 --- 2.1.52 2007/03/07
410 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
411 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
412 fd_set structure used as a bitmask for the FDs to be selected on.
414 Using ACX_PTHREAD macro to check for POSIX threads.
416 Fixed have-vsnprintf check.
418 --- 2.1.50 2007/02/23
420 Fixes for configure on BSD. Bug #900.
422 Added snprintf/vsnprintf wrappers for systems that don't have
423 limits (heavens forbid).
425 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
426 created before all previous tasks were completed and removed from the
427 task queue, the new task could be removed by a mistake.
429 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
431 Implemented pass-through CQL-to-PQF conversions. Bug #861.
433 Fixed bug #832: Problem with MARC/charset in yaz-client.
435 Fixed bug #668: save command line history for yaz-client.
437 Fixed bug #830: pkg-config support.
439 --- 2.1.48 2007/01/23
441 Extended ZOOM result set options with two options that may be read by
442 a client: resultSetStatus and presentStatus with values as specified for
444 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
446 Fixed bug #827: Using SSL fails on Debian etch.
448 Fixed bug #826: Weird looking chars for set of MARC records.
450 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
451 that is treated as an ItemOrder with itemRequest being an XML document
452 external. The value of "doc" is the content.
454 Extended the GFS search facility. New member of bend_search_rr
455 'estimated_hit_count' signals that hits is known to be an estmate
456 (higher or lower than real hit count). New member 'partial_resultset'
457 signals that the search was partial (hit count is lower or equal than
458 real hit count). For Z39.50, the information is stored in resultSetStatus
459 member of SearchResponse APDU. For SRU, the information is signalled
460 via SRU diagnostic 59: "Result set created with valid partial results
463 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
465 --- 2.1.46 2007/01/13
467 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
469 Added ZOOM_connection_peek_event.
471 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
472 the following new functions:
473 ZOOM_event_nonblock, ZOOM_connection_process,
474 ZOOM_connection_get_{socket,mask,timeout},
475 ZOOM_connection_fire_event_{timeout,socket}.
476 The existing blocking event handler, ZOOM_event, is a wrapper for the
477 + blocking ZOOM_event_sys_{poll,select}.
479 Implemented function ccl_xml_config which parses XML version of CCL
480 configuration (bug #798).
482 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
484 Added timings utility (yaz/timing.h)
486 --- 2.1.44 2007/01/03
488 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
491 Fixed bug #779: Rotation of apdu.log fails.
493 Fixed for character set conversions:
494 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
495 Honor G1 set in MARC-8 decoding.
497 --- 2.1.42 2006/12/17
499 Fixed bug #775: char conversion does not handle Alternative UTF-8
502 Implemented function yaz_marc_read_line which parses MARC line format
503 records. There is a wealth of formats out there. So far, this function
504 reads line records produced by yaz_marc_write_line.
506 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
507 more generic and easier to remember(!) options: -i format and -o format
508 which specifies input format and output format respectively - where
509 format is one of "marc", "marcxml", "line", "marcxchange".
511 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
512 does not print anything except warnings for records.
514 For yaz-marcdump, added support for MARC split into files (-s) with a given
517 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
518 spec, at http://www.loc.gov/standards/sru/record-update/
519 This has changed the binary layout of the following structs:
520 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
521 bend_update_rr . Patch by Ko van der Sloot.
523 Added GFS utility function bend_assoc_is_alive which returns 1 if
524 association is still alive (client is connected); 0 otherwise (client
525 closed connection). This allows busy servers to stop working for
528 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
529 been a separate piece of software. This version of ziffy has been modified
530 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
532 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
534 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
535 Client code may now interrogate options such as "init_opt_sort" to
536 find out whether the server claims to support various options.
538 --- 2.1.40 2006/11/27
540 Added utilities yaz_{set,get}_esn to set/get element set name from
543 Removed the build of libyazthread.la. The libyaz.so is the threaded version
544 of YAZ and has been so since YAZ 2.1.10.
546 Implemented ZOOM_record_error which returns error information for
547 record (surrogate diagnostic).
549 --- 2.1.38 2006/10/31
551 Updates for SRU Update by Ko van der Sloot:
552 1. Changed name from "operation" to "action"
553 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
554 versions in the code, marked as 'backward compatible'.
555 3. Added diagnostics for SRU Update.
557 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
559 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
561 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
563 For GFS, fixed problem with SRU diagnostic 'First record position out of
564 range' being issued for 0 hits.
566 zoomtst10 part of Windows Build.
568 --- 2.1.36 2006/10/13
570 Implemented yaz_filepath_comp which splits a path into file path
571 components (required by Zebra 2.0.3+).
573 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
574 BSD inspired license until now so this should not have any real impact on
575 anybody. See http://www.opensource.org/licenses/bsd-license.php
577 Fixed bug #687: Missing log lines.
579 Fixed bug #678: CQL to PQF translation does not preserve double-quote
582 Fixed bug #689: SRU diagnostics to be added.
584 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
585 whether a connection is idle (no more work do do).
587 --- 2.1.34 2006/10/04
589 Change type of optval from long to int for invocation of setsockopt with
590 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
592 Added support for specifying the max log file size for the Generic
593 Frontend Server. The size is given with option -r.
595 --- 2.1.32 2006/09/21
597 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
599 --- 2.1.30 2006/09/17
601 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
604 Fixed bug in Generic Frontend Server that could cause a server to stop
605 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
607 For the generic frontend server, the maximum record size is used as maximum
608 size of incoming packages (SRU + Z39.50). The value until was previously
609 only used in Z39.50 Init negotiation and, later, in a session controlled
610 sizes of records returned. This is controlled using -k option. It can be
611 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
613 --- 2.1.28 2006/09/04
615 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
618 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
620 New option for yaz-marcdump -lpos=value which allows setting a portion
621 of MARC header to a certain value.
623 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
625 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
626 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
628 --- 2.1.26 2006/08/15
630 Fixed problem with SRU mode type (soap, get, post) for yaz-client
633 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
635 --- 2.1.24 2006/08/08
637 Fixed MARC ISO2709 encoding routines to deal with character set
640 Minor changes to GFS logging. Database included in search request log
643 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
644 cached/multiple records.
646 Shared libraries are built by default on Unix+configure.
648 Changed cql2pqf transformation to use a different evaluation order. The
649 new order is: always, relation, structure, position, truncation, index
650 and relationModifier. Old order was: always, relation, relationModifier,
651 structure, index, position, truncation. Note that the the latter ones
652 override former ones for identical attributes.. The new scheme means that
653 it is possible to override any existing attribute with a relationModifier.
654 And also that it is possible to override everything for the index rule
655 (except the ones listed in relationModifier). No order is perfect but this
656 one, we believe, covers more real cases.. The "always" should have been
657 called "default", since the attributes there can be overridden with all
660 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
661 compilation phase, but also for yaz-config --cflags output. This allows
662 us to have public headers with Libxml2 stuff in them . It should also,
663 eventually, make Libxml2 checks redundant in packages using YAZ, such
666 --- 2.1.22 2006/06/15
668 Changed SRU update structure bend_update_rr so that SRU diagnostics are
669 stored in uri, message and details.. Previously diagnostics were stored
670 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
671 compatibility.. but he's probably the only one affected, so.
673 Added support for CCL, compiled on the client side, in ZOOM-C. This
674 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
675 input; the resulting query objects can be used for for searching with
676 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
678 YAZ' configure searches for OpenSSL by default.
680 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
681 SL_CTX_use_certificate_file. See
682 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
683 for more info. Thanks to Ko van der Sloot.
685 --- 2.1.20 2006/06/02
687 Bug #600: SRU GET, POST support for yaz-client. Introduced
688 command 'sru' which selects method SOAP/GET/POST.
690 Allow missingValueAction to be specified for the sortspec string -
691 function yaz_sort_spec. By default, the missing value action is null.
692 Use ! to specify "abort". Use = followed by stringvalue to specify default
695 Ensured that Present-handler (if defined) is called in GFS before any call to
696 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
697 searchRetrieve requests.
699 Documentation for YAZ is now based on the Docbook XML/XSLT using
700 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
701 is no longer depending on jade/openjade or docbook-to-man scripts.
702 PDF is no longer part of the distribution - but can optionally be
703 made using DSSSL/jadetex or FOP.
705 Added retrieval handling support in Generic Frontend Server to support
706 conversion between MARC/XML as well as XSLTtransforms. See
707 etc/yazgfs.xml for an example.
709 Added Authentication support to Generic Frontend Server in SRU
710 mode. Authentication using HTTP Basic is supported, as is the use
711 of 'x-username' and 'x-password' parameters in the request itself.
713 Added support for a new character set MARC8s identical to MARC8 except
714 that it converts combined characters to single Unicode characters in the
715 Latin-1 range (when possible).
717 --- 2.1.18 2006/04/24
719 ASN.1 compiler 0.4: generates brief Doxygen file header for
720 generated .h/.c files.
722 Utility yaz_iconv now supports conversion to MARC-8.
724 New facilities for the MARC module. The reading - and writing of
725 content are separate methods for the yaz_marc_t handle. The following
726 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
727 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
728 format). Write functions have prefix yaz_marc_write_.. The existing
729 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
730 available. Removed support for OAI-MARC and simplexml (not the
731 simplexml from PHP5).
733 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
734 to be returned for this connection.
736 --- 2.1.16 2006/03/31
738 Allow multiple languages and charsets to be specified with
739 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
740 negcharset iso-8859-1,utf-8
742 Translation of proximity nodes from CQL into PQF now works.
744 Moved to automake 1.8, 1.9.
746 Added function yaz_log_set_handler which allows a log handler to be
747 installed. This handler will be called for all log messages. Output
748 to file is also produced; but that can be disabled by passing NULL
749 fname to yaz_log_init_file.
751 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
753 For SRW (including GFS), accept application/soap+xml as content-type
756 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
757 produces NO stylesheet reference even if a default stylesheet is specified
760 --- 2.1.14 2006/03/14
762 Updated Windows package to include yazd.dll + yazd.lib for the
763 Development component.
765 If the environment variable YAZ_LOG is set, then it is used as a
766 string indicating the default level of logging to use if not
767 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
768 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
769 used as before. So, for example, to omit warnings from YAZ logging,
772 cql_transform() now map structure and other attributes before indexes,
773 so that index-specific structures and other attributes can override
774 defaults. So now a combination of mapping specifications such as:
776 index.dc.date = 1=date-modified 4=5
777 does the right thing.
779 cql_transform() now also respects the "always" mapping specification,
780 which establishes an initial set of attributes to be used for all
781 terms except where overridden by more specific attributes associated
782 with the index, relation or modifier.
784 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
785 which mode to use; one of "post", "get" or "soap" (SRW, default).
787 Fixes for yaz_iconv routines: changed trie-based character set conversions
788 to use only non-negative values for bit fields due to Sun's C compiler not
789 supporting negative values.
791 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
792 sequences where not read correctly. Fix by Rustam Usmanov.
794 Updated win/makefile to use options, settings which makes things
795 compile with VS C 2005.
797 --- 2.1.12 2006/02/01
799 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
801 In ZOOM socket code, use select instead of poll on MacOSX.
803 ZOOM-C now support client-side compilation of CQL into RPN that is
804 sent to the server, enabling CQL to be used against all Z39.50
805 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
806 ZOOM_query object, and submit it using ZOOM_connection_search().
807 The CQL-to-RPN translation uses a configuration file, the name of
808 which must be specified in the Connection's "cqlfile" option.
810 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
811 function, which takes as its start-term parameter a ZOOM_query object
812 (which may have had either CQL or RPN set into it).
815 --- 2.1.10 2005/11/29
817 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
818 GFS to support this as well. Backend handler, bend_srw_update, does the
819 update work. Code contributed by Ko van der Sloot.
821 Allow retrieval of Search Result-1 information in ZOOM by the use of
822 options that are attached to a result set. ZOOM documentation updated
825 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
826 UTF-8 conversion. Patch by Raj Patel.
828 Added option -m to GFS to control formatting of timestamps in log file.
830 Added 'exit' as synonym for 'quit' in yaz-client
832 Added support for specifying SRW resultSetId + resultSetIdleTime in a
833 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
834 for the new members. Patch by Ko van der Sloot.
836 Added support for SRU POST. It is supported for content-type
837 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
839 Do not build the separate Multi-threaded (MT) library libyazthread.la.
840 Instead make the library libyaz.la multi-threaded. Threading as a whole
841 can still be disabled by configure option --disable-threads. Previosly,
842 with older GLIBCs there were problems with MT libs under Apache. This
843 has now been fixed a long time ago.
845 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
848 CQL module modified to be case insensitive for relations/indexes/operations.
850 Fixed bug in CQL transform code: incorrect value relationModifieder
853 Added 'show all' command for yaz-client which retrieves all results
856 Added new yaz-client, xmles, which takes a (private) OID and
857 a document to be sent as an extended service request.
859 Describe new yaz-client commands wait_response and set_auto_wait.
861 Increase TCP/IP listener backlog from 3 (which I am guessing was
862 copied from the SunOS manual entry way back when) so SOMAXCONN, so
863 that the socket will queue as many incoming connections as it's able
864 to handle ongoing connections. In other words, it will never now
865 refuse a connection that it would be able to handle merely because
866 it's not got around to accepting() enough of the pending connections
867 yet. This is the behaviour anyway under Linux, where the listen()
868 argument is ignored; but not under BSD and on systems such as
869 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
870 YAZ-based servers should now be uniform across operating systems in
873 yaz-marcdump uses 64-bit file access on some systems. This is enabled
874 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
875 This allows yaz-marcdump to read large MARC batches (>2 GB).
877 Modified all YAZ source files - except the source which is auto-generated
878 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
881 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
882 corresponding to the existing *_setl() function. These allow option
883 values containing arbitrary valuues.
885 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
886 ZOOM_resultset_sort() in new applications. Its behaviour is identical
887 except that it returns an indicator of whether or not the sort
888 criterion was accepted (0 for OK, -1 for invalid).
892 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
893 MARC output rather than returning "new" buffer.
895 yaz-client warns about unknown init options.
897 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
901 Added support for SRW sort in Generic Frontend Server. Patch
902 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
903 sortKeys - or NULL if none is provided.
905 Fixed bug #307: It was impossible to specify indefinite/no timeout
906 for ZOOM_event. Special timeout value -1 now means indefinite timeout
909 Added support for multiple languages and charsets to be specified in
910 ZOOM. Each charset/language is separated by a blank. If negotiation is
911 in effect in init-response, Option
912 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
913 Code based on patch by Vasiliy Osadchuk.
915 Fixed bug #306: infinite recursion that occurred when calling
916 yaz_log_level_init as the first call (before other log level or
919 Fixed bug in scan handling in front end server: if preferred-Position-In-
920 Response was non-present, a NULL pointer referece was performed.
924 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
925 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
926 now defined for all those error codes. So instead of putting 109 in
927 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
928 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
930 Modified the yaz-marcdump utility to skip garbage bytes between MARC
933 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
935 Program yaz-client now exits and produces an error message if multiple
936 Z39.50 servers are specified on the command line (none or one allowed
939 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
944 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
946 Fixed bug #272: Preserve spacing for CCL terms.
950 Added support for virtual hosts and multiple backend servers for
951 the YAZ frontend server. The configution is XML based and
952 support specificition of CQL to RPN mappings and explain information.
953 See section "Virtual Hosts" in the YAZ manual.
955 Extended OPAC display utility. OPAC display utility renders
956 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
957 to supplement yaz_marc_decode_wrbuf.
959 Fixed a bug in MARC decoder that could caused it to crash for some
960 invalid MARC records. More diagnostics and warnings where added in
961 XML output (warnings, etc are stored in comments).
963 --- 2.0.34 2005/02/08
965 Fixes for UNIX domain sockets. Bug #261.
967 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
969 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
970 Added yaz_marc_subfield_str which defines subfield lead string which is
971 used in YAZ_MARC_LINE format. Default string is blank+$. Added
972 yaz_marc_endline_str which defines end of fields string used in
973 YAZ_MARC_LINE format. Default string is newline.
975 Experimental support for MarcXChange. This format can be produced
976 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
977 http://www.bs.dk/standards/MarcXchange.xsd
979 Added yaz-client commands scansize that sets maximum number of
980 entries to be returned by scan.
982 --- 2.0.32 2005/01/11
984 Added support for SRW scan in yaz-client and Generic Frontend Server.
986 * Added whereInList member to SRW Scan Term.
988 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
990 Fixed NMEM system to return aligned blocks on the smallest boundaries
991 that are suitably aligned for all possible types on the particular
992 architecture YAZ is being built for.
994 --- 2.0.30 2005/01/04
996 Fixed numerious warnings that was issued with newer versions of GCC.
998 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
999 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1002 Make YAZ Generic Frontend Server slightly faster.
1004 Enhance (and reduce) logging for Generic Frontend Server.
1006 Revert YAZ log system so that it flushes every write operation
1007 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1009 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1010 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1011 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1012 will effectively disable old definitions.
1014 --- 2.0.28 2004/11/09
1016 Added yaz_log_time_format which specifies log format using
1019 Added yaz_log_module_level which returns mask for a module. Value
1020 is non-zero mask a if module is enabled; zero if disabled.
1022 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1023 in include/yaz/cql.h.
1025 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1027 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1029 Fixed bug #172: RPM builds does not enable SSL.
1031 Doxyfile.in part of dist. Doxyfile generated by configure.
1033 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1034 are given and the corresponding component does not exist.
1036 Extend CCL documentation in YAZ reference. Describe r=r.
1038 --- 2.0.26 2004/10/01
1040 Fixed MARC->MARCXML conversion to properly deal with
1041 fields, subfields, indicators having non-ASCII characters.
1043 Fixed MARC->MARCXML conversion so that ASCII control characters
1044 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1047 Added YAZ GFS support for conversion from Z39.50 surrogate
1048 diagnostics to SRW surrogate diagnostics.
1050 Bug fix: YAZ GFS did not return schema in explainResponse.
1052 --- 2.0.25 2004/09/30
1054 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1055 now converts recordSchema to elementSetName as well as schema URI.
1057 Fixed bug in COMSTACK that prevented HTTP request packages from being
1060 --- 2.0.24 2004/09/29
1062 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1063 does not require white-space before and after the dash in a range, e.g.
1064 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1067 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1068 due to new GCC removing "redundant" code.
1070 Added yaz-client commands scanpos and scanstep that sets preferred
1071 position and step-size for scan.
1073 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1075 Added CCL utility ccl_qual_buf which parses one or more CCL
1076 spec lines in a buffer.
1078 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1079 of name and value - ignoring empty lines and comments.
1081 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1083 Added odr_get_element_path which returns current element path for an
1084 ODR handle. This utility is useful in error handling or user-defined
1087 Added ODR_PRINT utility odr_set_stream which is is a more generic
1088 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1089 to a write function and pointer to close function. The close function - if
1090 non-NULL - will be called during odr_destroy.
1092 Fixed bug in CCL parser where truncation char was not removed from
1093 right side when truncation=both was in effect.
1095 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1098 --- 2.0.23 2004/08/11
1100 Fix buffer overrun in CQL parser when dealing with proximity (%).
1102 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1103 to UTF-8/UCS conversion is now only based on codetables.xml.
1105 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1107 --- 2.0.22 2004/08/06
1109 Add support for more "commit changes" in ZOOM (uses Extended Services).
1111 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1114 Yet another small fix for configure of SSL.
1116 --- 2.0.21 2004/05/14
1118 Fix SSL libs for configure when --with-openssl=DIR is given.
1120 --- 2.0.20 2004/05/10
1122 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1124 SSL comstack now uses yaz.pem certificate file on server side
1125 by default. Certificate filename can be configured by calling
1126 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1128 Fix bug regarding multiple calls to ZOOM_connection_connect.
1130 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1132 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1133 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1135 ZOOM now allows inspection of X509 peer certificate for verification.
1136 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1138 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1139 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1140 as "modular" but it simplifies things.
1142 Added cs_get_peer_certificate to that returns peer X509 PEM.
1144 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1145 NULL if SSL is unavailable.
1147 Documentation about MARC decoding tools.
1149 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1151 --- 2.0.19 2004/03/30
1153 Rename CHANGELOG to NEWS to follow GNU style packing.
1155 Fix bug with missing initialization of member in init_diagnostics.
1156 This bug affects threaded version of GFS server.
1158 --- 2.0.18 2004/03/20
1160 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1163 Ensure zlib.dll is packed with Windows install.
1165 --- 2.0.17 2004/03/17
1167 Fix encoding of xsd:string to use text instead of CDATA.
1169 Fix endless loop in CQL parser with unbalanced ".
1171 Use a more compact way to store MARC-8 conversion tables.
1173 --- 2.0.16 2004/03/16 Debian only
1175 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1178 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1183 --- 2.0.15 2004/03/01
1185 Another fix for decoding of XML packed records.
1187 --- 2.0.14 2004/02/25
1189 Fixes for Chunked encoding. White space not ignored after length spec.
1191 Update NS and use default NS for SRW diagnostic elements.
1193 --- 2.0.13 2004/02/23
1195 Implement ZOOM_resultset_cache_reset which resets record cache.
1197 Implement ZOOM_resultset_sort which sorts a result set.
1199 Implement chunked HTTP transfer.
1201 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1203 --- 2.0.12 2004/02/16
1205 Added member 'schema' to bend_explain_rr structure so that backend
1206 can specify explain record identifier. Defaults to Zeerex 2.0.
1208 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1210 --- 2.0.11 2004/02/16
1212 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1215 Added init command for yaz-client which sends "extra" init request.
1217 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1218 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1220 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1222 Make ZOOM error code for "invalid query".
1224 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1226 --- 2.0.10 2004/02/05
1228 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1231 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1233 Added option -p <file> to make Generic Frontend Server to write PID file.
1235 Added option -D to put Generic Frontend Server in background on its own.
1237 Make ZOOM C recognize option "password". If unset, "pass" is used
1238 (for backwards compatibility).
1240 Fixed a bug in Generic Frontend Server that could make it crash if a
1241 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1244 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1245 Must be issued before open, in order to be in effect.
1247 --- 2.0.9-6 2004/01/12 Debian/Windows
1249 Make the SRU server more picky WRT unknown params, etc.
1251 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1253 New YAZ client command, options, that sets Z39.50 options.
1255 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1256 options from a string of tokens (one token for each option bit).
1258 Update SRW diagnostic code messages.
1260 --- 2.0.9-5 2004/01/07 Debian/Windows
1262 Handle user defined stylesheet for SRW/SRU.
1264 --- 2.0.9-4 2004/01/06 Debian/Windows
1266 Fix bug in decoding of Content-Length.
1268 --- 2.0.9-3 2004/01/06 Debian/Windows
1270 Fix a bug with decoding of XML packed records.
1272 --- 2.0.9-2 2004/01/05 Debian only
1274 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1276 Fix bug in SRW/SRU diagnostics decoding.
1278 --- 2.0.9 2004/01/05
1280 Fixed bug in Generic Frontend Server which could drop records exceeding
1281 preferred message size. Reported and fixed by Irina Dijour.
1283 Fixed calculation of package size for structured records in Generic
1284 Frontend Server. Reported and fixed by Irina Dijour.
1286 Fixed namespace for SRW/SRU diagnostics.
1288 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1290 --- 2.0.8 2003/12/22
1292 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1293 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1296 CQL changes to reflect recent changes to the specification:
1297 * Documentation talks about context sets instead of index sets.
1298 * Documentation talks about indexes instead of qualifiers.
1299 * The CQL-to-PQF transformer's configuration file now uses
1300 "index.set.name = <attributes>" instead of the old form
1301 "qualifier.set.name = <attributes>". (Both forms are still
1302 understood but the latter is deprecated.)
1303 * CQL terms with no explicit index specified are now interpreted as
1304 cql.serverChoice instead of srw.serverChoice (which of course
1305 behaves exactly the same.)
1307 --- 2.0.7 2003/12/16
1309 MARC conversion can now generate ISO2709 output in another
1310 character set. yaz-marcdump uses this facility if you invoke it
1313 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1314 functions from there can be used from C++.
1316 --- 2.0.6 2003/12/04
1318 Frontend server now transfers memory from decoded packages to stream
1321 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1322 references to show up.
1324 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1325 the ZOOM Abstract API. The older names for the same options are still
1326 also supported for the benefit of old applications.
1328 ZOOM-C supports "implementationId" and "implementationVersion" options
1329 to go along with "implementationName". These allow the user code to
1330 specify identification strings to be sent to servers.
1331 Add OID for the new ExtLite attribute set.
1333 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1334 as requested/supplid by Ere Maijala <ere@atp.fi>
1336 For generic frontend server, reverse the order of
1337 "toolkit-supplied / application-supplied" strings sent as implementationId,
1338 Name and Version. Also, remove the spaces around the slash. This brings
1339 the GFS in line with the behaviour of ZOOM-C on the client side.
1341 Add function ZOOM_scanset_display_term.
1343 yaz-client shows scan displayTerm if present.
1345 Utility yaz-iconv is now installed by default along with the man page
1348 Extend configure check for OpenSSL to use pkg-config where available (such
1351 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1352 server to specify uid/gid/mask for socket using the format
1353 unix:[user=uid,][group=gid,][umask=mask,]file=path
1354 If file= is omitted the existing format is assumed, e.g.
1356 in which case the mask is 0666 (rw for everybody).
1358 Major restructure of YAZ source. All source in libyaz is in src directory.
1359 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1360 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1362 Added man page for utility yaz-marcdump (used to be called marcdump).
1363 yaz-marcdump is installed by 'make install'.
1365 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1366 of incoming package failed.
1368 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1370 Change prototype of odr_perror: add const to message string.
1372 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1374 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1375 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1376 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1377 DNS lookup. There should not be any compatibility problems with this
1378 assuming that blocking=1 or 0 is used.
1380 Fix bad reference in UNIX comstack in function cs_addrstr.
1382 Fix for compilation on AIX.
1384 The generic front-end server (server/seshigh.c) now supports returning
1385 Init diagnostics to the client in User-information-field, in
1386 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1389 --- 2.0.4 2003/09/04
1391 Allow any CQL relation (not just all,any,exact,scr).
1393 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1394 that features the same UI.
1396 Implemented command update0 in YAZ client which is equivalent to
1397 update but uses old of Ext Update ASN.1.
1399 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1400 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1401 Previously no OID was used for this info.
1403 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1404 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1405 returns 'malformed search term' otherwise.
1407 SortResponse member resultCount now set to NULL in sort handler of
1410 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1413 Add three new utility functions for translating OIDs between various
1414 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1415 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1416 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1417 char *oid_to_dotstring(const int *oid, char *oidbuf);
1418 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1420 Reverted modifications for ES Update definition for z_IU0Update
1421 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1422 is back to YAZ 2.0.2.
1424 String value attributes for CCL parser.
1426 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1427 which their FirstSearch server returns in Init responses, sometimes
1428 carrying useful diagnostic information when Init fails. This has the
1429 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1430 "z39.50/oclcui.asn", where its definition is somewhat different from
1431 what OCLC document on their web-site, as required to interoperate with
1434 Support for anonymous authentication in yaz-client. Use the command
1437 * Fix the OID of the Index Data-local "admin" Extended Service from
1438 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1439 the 1000, which indicates a locally-defined OID, was a mistake.
1441 --- 2.0.3 2003/06/20
1443 Fix CCL directive @case handling so that it affects string match for
1444 both CCL keywords and qualifiers.
1446 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1447 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1448 Decoder has been updated with ASN.1 changes as listed in
1449 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1450 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1451 z_IUUpdate, remains unchanged.
1453 ZOOM_record_get may now return a record in a specific character set.
1454 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1455 "from" is the character set of record as returned by target. "to" is
1456 the character set to be returned. If omitted, "to" is UTF-8.
1458 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1460 New ODR utility, odr_getelement, which returns name of element for
1461 which encoding/decoding failed.
1463 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1464 in cases where a required element was omitted.
1466 Bug fix: some MARC8 sequences were not converted.
1468 New ZOOM option "step" which specifies number of records to be
1469 retrieved in one chunk. Used in conjunction with "start" and "count".
1471 SRW support for yaz-client. Use scheme http: to use it, e.g.
1474 yaz-client no longer does (un)intelligent character set conversions
1475 by default. Can be enabled with charset and marc_charset commands.
1477 xmalloc trace fix for 64-bit systems such as DEC alpha.
1479 Solaris 2.6 compile fix.
1481 New function, cql_strerror() translates SRW error codes, as returned
1482 by cql_transform_error(), into human-readable English strings. Used
1483 in yaz-client diagnostics when appropriate.
1485 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1486 converts it into a type-1 query which is sent to the server. This
1487 makes CQL available for use with all Z-servers, as opposed to the tiny
1488 minority that can handle CQL queries themselves.
1490 --- 2.0.2 2003/04/28
1492 New Debian package layout similar to the Redhat Package layout.
1494 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1495 and search result respectively.
1497 --- 2.0.1 2003/04/25
1499 Redhat package is now several packages: libyaz (runtime libraries),
1500 libyaz-devel (development and documentation, and yaz (utility programs).
1501 Package spec file by Morten Bogeskov.
1503 New member 'schema' in struct bend_fetch_rr which the name of requested
1504 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1505 handler MAY set this to reflect the schema of the returned record.
1507 New member 'display_term' in struct scan_entry. GFS now sets member entries
1508 and allocates scan entries to be filled by user scan handler. In previous
1509 version, entries member was allocated by the scan handler. That still works,
1510 but the GFS will ignore member display_term - assuming it was NOT set by
1511 the handler. The fact that the GFS now allocates the entries both allows
1512 for new members and makes a scan handler easier to write.
1514 Fix CQL lex buffer overflow.
1516 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1517 SRU default recordPacking is string.
1519 SRU protocol support for frontend server.
1521 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1523 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1525 Added scan for the ZOOM shell (zoomsh).
1529 * String Identifers for Schemas (Amendment 5).
1530 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1531 Old definition for schema
1532 Odr_oid *schema; /* OPT */
1537 Z_InternationalString *uri;
1538 #define Z_Schema_oid 1
1539 #define Z_Schema_uri 2
1542 * resultCount parameter to Sort Response (Amendment 1).
1543 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1545 Support for SRW 1.0 over HTTP. This is an optional feature and
1546 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1549 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1550 on the same port. SRW SearchRetrieveRequests are mapped
1551 to bend_init,bend_search,bend_fetch,bend_close.
1553 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1555 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1556 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1558 ZOOM connections are SRW based if schem http is used for hostname
1559 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1560 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1562 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1563 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1564 distance=n, order=true/false, relation=le, prox unit=word. If
1565 n is omitted, distance 1 is used.
1567 Fixed problem with C compiler include path in wrong order.
1569 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1570 on Solaris. Patch from Ko van der Sloot.
1572 New MARC decode API. All new functions operate on a yaz_marc_t
1573 handle. The most important new functions are: yaz_marc_create,
1574 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1575 decode and destroy respectively. Decoder can produce formats
1576 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1577 include/yaz/marcdisp.h.
1579 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1580 to UTF-8, UCS-32, wchar_t or Latin-1.
1582 * Prototypes for yaz_iconv_-functions moved to separate header
1583 include/yaz/yaz-iconv.h.
1585 Make a few private functions 'static' in unix.c. This prevents
1586 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1588 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1589 are set when Init Response is received.
1591 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1592 but returns diagnostic set as well.
1594 New function yaz_strerror which is a portable wrapper for
1595 strerror/strerror_r/GetLastMessage.
1597 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1598 is returned for MARC. If type is "oai", then OAI MARC is returned.
1600 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1603 --- 1.9.2 2002/11/26
1605 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1607 Fix bad race conditions on SIGTERM and terminate gracefully in
1610 Move retrieval (data1) module to Zebra since nobody seems to be
1613 Add GRS-1 render for ZOOM using same format as yaz-client.
1615 --- 1.9.1 2002/10/05
1617 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1619 Fix broken ESpec handling in data1 module.
1621 SGML reader parses comments and makes them part of the data1 tree.
1623 Added several type casts so that YAZ compiles as C++ code.
1625 ZOOM didn't handle PDU encoding failures properly.
1627 Added more Bib-1 diagnostics (approved extensions).
1629 GNU configure: better check for iconv.
1631 More portable use of accept, getpeername. Check for socklen_t. Use
1632 int/size_t if socklen_t is not defined.
1636 PQF parser rejects bad queries - including those with extra
1637 characters in them. PQF parser used to silently ignore that.
1638 Cleaner API for PQF added, which allows you to get detailed
1639 error information for bad queries (see yaz/pquery.h).
1641 Fixed bug in ZOOM_record_get for type "database".
1643 Implemented mini iconv library supporting conversions between
1644 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1646 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1648 --- 1.8.9 2002/08/20
1650 Fixed ZOOM C record cache so that preferredRecordSyntax and
1651 elementSetName is used to check for already fetched records.
1653 --- 1.8.8 2002/08/02
1655 Added three members in bend_initrequest structure to facilitate
1656 character set negotiation.
1658 Fixed a bug in frontend server that could cause indefinite
1659 loops under rare conditions.
1661 Revised character set utilities (charneg.h) so that encoding
1662 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1664 For PQF, directive @term <type> sets term type for Scan/Search.
1665 Here <type> is general, string, numeric, null. The term type
1666 is inherited - just like @attr.
1668 New call odr_set_charset that sets character set conversion for
1669 international-strings on a ODR stream. Prototype is:
1670 int odr_set_charset(ODR o, const char *to, const char *from);
1671 The InternationalString is still represented as C string in YAZ
1672 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1673 won't). On the protocol level, you can use any encoding.
1675 Support for UNIX sockets in ZOOM.
1677 Solaris recv sometimes returns errno == ENOENT. It is treated as
1678 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1680 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1681 both client and server. Code by Morten Bogeskov.
1683 --- 1.8.7 2002/05/22
1685 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1686 that they can be used directly from Visual Basic. You must recompile
1687 your windows APP if you're using ZOOM.
1689 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1690 Commands "lang" and "charset" sets language and character set respectively.
1691 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1692 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1694 Attributes from multiple CCL fields may be OR'ed rather than merged
1695 using directive "@field or". Fields are still merged by default -
1696 equivalent to "@field merge".
1698 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1701 Fixed bug in zget for parameter ExtendedServicesResponse.
1705 --- 1.8.6 2002/03/25
1707 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1709 Client displays USR.1:SearchResult-1 (hits per term).
1711 Additional Search Info for search in Generic Frontend Server.
1713 Fixed CCL parsing of "field=s".
1715 WIN32 installer - using the excellent NSIS software from nullsoft.
1717 Fixed CCL parsing of "field = - <number>".
1719 Added function yaz_marc_decode that decodes MARC for line mode
1720 display or XML (similar to that used by JZKit).
1722 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1723 Z39.50. But ISO/ILL was, however.
1725 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1726 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1728 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1729 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1731 --- 1.8.5 2002/02/03
1733 New YAZ client features: Command completion and new commands:
1734 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1735 Code provided by Jacob Poulsen.
1737 New call oid_trav, that visits all registered OIDs via callback.
1739 Function ZOOM_record_get now returns const char pointer rather than
1740 void pointer. It saves a lot of type casts.
1742 For YAZ client, command "auth" now allows you to set authentication
1743 in IdPass style. It is enabled when three tokens are given - order
1744 is user, group and password.
1746 Fix memory leaks in MARC record handling for ZOOM.
1748 New option for YAZ client, -k <kilobytes> that sets
1749 maximum record size. Similar to -k option for generic frontend
1750 server and yaz-ztest.
1752 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1754 Prefix query parser reports "fail" when bad attribute set is given.
1756 Fix in MARC decoder. Proximity logging. Fix for attribute set
1757 in scan handler for server. Patches by Shigeru Ishida.
1759 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1762 Configure option --with-openssl=<dir> now works when a directory is
1763 specified. Patch provided by Morten Bogeskov.
1765 New option for YAZ client, -u <auth>, that sets authentication.
1767 ZOOM fix: error information was sometimes "missing", since error
1768 was cleared/reset too when it shouldn't.
1770 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1772 --- 1.8.4 2002/01/04
1774 Scan for ZOOM API. New object ZOOM_scanset. New functions
1775 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1776 ZOOM_scanset_destroy.
1778 New ZOOM function, ZOOM_connection_last_event, that returns type
1779 of last event (such as "receive data", "send data", "apdu received",
1782 New ZOOM option, schema, that specifies schema for retrieval.
1784 New CCL feature. Qualifiers can be aliases for one or more
1785 other qualifiers (if more than one is given, OR is used).
1787 ZOOM uses named result sets if target supports it.
1789 Two new YAZ client commands: . (dot, which sources a script of YAZ
1790 client commands), and ! (to execute shell command.). Implemented
1793 Working on Debian packages.
1795 --- 1.8.3 2001/11/19
1797 YAZ client enables named result sets only if target supports it.
1799 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1801 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1802 with key="host" to get same result.
1804 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1805 Function Z3950_resultset_record(s) returns references to records
1806 "owned" by resultset. To become owner use Z3950_record_clone.
1808 Function z_ext_record handles Extended Services. Thanks to
1811 --- 1.8.2 2001/11/12
1813 CCL Parser fix: ignore token comma when dealing with and-lists.
1815 Documentation updates for COMSTACK.
1817 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1818 Changed prototype Z3950_records. For some functions, int parameters
1819 were changed to size_t.
1821 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1824 New MARC decode/display function, marc_display_exl, which properly rejects
1825 non-ISO2709 records. YAZ client uses it.
1827 --- 1.8.1 2001/10/29
1829 Fix bug: local attribute set wasn't set correctly in PQF strings.
1833 * Old Z39.50 codecs no longer supported.
1835 Added ZOOM C binding. See http://zoom.z3950.org/
1837 Renamed states for COMSTACKs to avoid confusion with events.
1839 Implemented cs_look and proper cs_rcvconnect.
1841 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1843 Configure detects POSIX threads on OpenBSD.
1845 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1846 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1848 When error is returned from present handler, non-surrogate diagnostic
1849 is returned in present response (and fetch handler is no longer called).
1851 * Minor adjustments to pquery parser (PQF). Token characters may be
1852 escaped by using backslash (C-style).
1854 PQF parser allows string attribute values to be specified. For @attr,
1855 non-numeric characters after the equal-sign are treated as strings
1856 (e.g. @attr 9=title).
1858 CCL trunction character may be defined (@truncation in file)
1860 * function zget_ExtendedServicesRequest sets waitAction to
1861 waitIfPossible (was wait).
1863 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1866 CCL operator names may be set in field definition files (CCL_bibset).
1867 See ccl/bib1 for an example.
1869 Fixes in ASN.1 compiler for C++ compatibility.
1871 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1872 and "op_or" to avoid conflict with C++.
1874 Fixed problem with GNU readline detection on Redhat 7.0.
1876 Added step-size for Scan backend handler.
1878 Fixed bug that made the frontend server crash when no attribute
1879 set was specified for scan.
1881 Front-end server automatically switches to original working directory
1882 when installed as an NT service. Previously -w had to be specified to
1885 Added extended attributes for retrieval module (data1), so that data1
1886 records carry d1_readXML/SGML attributes. d1_read also supports
1887 null-data rules ( <tag/>)
1889 On UNIX when POSIX threads are available, a separate library libyazthread
1890 is created. Programmers should link with that library and the yaz library
1891 when using threads. The reason for the split was that some applications
1892 on Linux, such as Apache, doesn't work well when using shared objects that
1895 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1896 (or any frontend server) in SSL mode by specifying ssl: followed by
1897 address. Only tested on UNIX.
1899 Added feature for CCL module. Virtual structure s=al or s=ol generates
1900 and-list and or-list respectively instead of phrase search.
1904 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1905 log_mask_str. This was done to avoid name conflicts with other libraries
1906 (such as other PHP extensions).
1908 Added raw OID member for preferred record syntax (request_format_raw)
1909 and returned record syntax (output_format_raw) for backend fetch method.
1911 Config file yaz-config now accepts options so that it returns specific
1912 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1914 Shared library support for UNIX using GNU libtool.
1916 * Modified backend interface. Request/Response struct's replaced by
1917 one read/write C struct. For example bend_fetchrequest and
1918 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1919 Every handler - even search has to be registered in bend_init
1920 handler. This means that the YAZ library no longer refers to
1921 external functions and it makes it possible to make the whole
1922 thing a single DLL/SO.
1924 Added Segment handler for backend server.
1926 Added Zmbol/Zebra administrative functions to YAZ client.
1928 Threaded frontend server on UNIX (when POSIX Threads are available).
1929 Starting the server with option -T enables multi-threading.
1933 Added configure option --enable-comp/disable-comp to control use
1934 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1935 located in sub directory asn.
1937 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1938 in ${exec_prefix}/bin along with the other programs yaz-client and
1941 GNU automake used to maintain makefiles.
1943 Added several OID's.
1945 Changed retrieval module so that we can load records with no abstract
1946 syntax defined. Tagpaths in these records are fully composed of string
1949 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1953 On UNIX, the generated makefile now supports a proper 'make install'.
1954 The prefix can be set via GNU configure to set the install location
1955 (default is /usr/local).
1957 * YAZ programs client and ztest were renamed to yaz-client and
1958 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1959 locations, such as /usr/bin,/usr/local/bin,etc.
1961 * YAZ Header files were moved from include to include/yaz. YAZ Header
1962 files are referred to as include <yaz/log.h> rather than <log.h>.
1963 The YAZ include path (-I ..) is therefore the same as before. Programmers
1964 should update their #include statements or use -Ipath/include/yaz
1965 instead. The main motivation for doing this change is that YAZ header files
1966 can be installed in "standard" locations /usr/include,/usr/local/include
1967 without introducing conflicts, since ALL YAZ header files are stored
1968 in subdirectory yaz (under /usr/include for example).
1970 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1971 rather than project/workspace files. We switched because project files
1972 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1975 Changed name of logging function, logf, to yaz_log, to prevent name
1976 clash with some math-log functions. The YAZ header log.h defines logf
1977 to yaz_log (#define) so there should be no incompatibilities by this
1980 Added bend_start/bend_stop handlers for server. These handler are
1981 called on start/stop of server. For windows they are called whenever
1982 a service is started/stopped.
1984 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1985 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1986 in util/yc.tcl. The auto-generated C code structures are, in a few
1987 cases, incompatible with the old decoders. There are differences in the
1988 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1989 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1990 The preprocessor variable ASN_COMPILED is defined when the compiled
1991 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1992 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1993 wish to use the old encoders/decoders you can specify --disable-yc
1996 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1997 version so that it supports both new - and old version of DB Update
1999 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2000 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2001 change. The name parameter can be set to 0 in which no name is specified
2002 for the construction. The macros odr_implicit and odr_explicit sets name
2003 parameter to zero for the construction involved. New macros
2004 odr_implicit_tag and odr_explicit_tag are similar to the others,
2005 except that a name parameter is added. For programmers' that don't use
2006 ODR they probably only need to change the call to z_APDU and z_External.
2008 Added access control facility by interfacing the TCP wrapper library.
2009 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2010 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2011 name of the daemon and enables the access control as specified in
2012 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2014 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2015 den Dool <H.M.vdnDool@kub.nl>.
2017 Added reference ID parameter to most functions in server API - refer
2018 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2020 Changed name of ccl library to libccl.a (was ccl.a).
2022 Fixed bug in decoder for Explain (Category TargetInfo).
2024 Added support for GNU readline in client. Thanks to Jacob Poulsen
2025 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2027 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2028 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2029 IMPLEMENTATION! This change was made to the development version before
2030 the ZIG decided to retract the amendment. If any users MUST be
2031 compatible with the original Update definition, PLEASE CONTACT US, and
2032 we will include a separate definition corresponding to the old Update
2033 ES. Note that because of the change to the ASN.1 of the
2034 TaskPackageRecordStructure we cannot define a single structure that
2035 will support both versions.
2037 * Added const modifier to buffer parameter for some ODR/BER encoding
2038 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2039 completeWAIS, odr_dumpBER.
2041 Fixed bug in client.c which caused a crash when a scanResponse didn't
2042 contain positionOfTerm.
2044 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2045 * will cause an error in a client if a non-YAZ target sends both a
2046 * list of Scan entries and non-surrogate diagnostics.
2048 Retrieval module enhancements. Tag sets may be typed in the reference
2049 to it. From the .abs-file the "tagset" directive takes a third optional
2050 integer type for the tag set referenced. From a .tag-file the "include"
2051 directive takes a third optional type as well. The old "type" directive
2052 in the tag set itself is still recognized but acts as the default type
2055 Backend interface change. Individual Scan terms returned from bend_scan
2056 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2057 in include/backend.h.
2059 Retrieval module enhancements. Multiple tag sets and attribute sets may
2060 be specified in abstract syntax specs. Revised the error/warning for
2061 logging messages reported by the retrieval module when reading the
2064 Object Identifier system (oid_..) changed. The API is backwards
2065 compatible but the oid-routines now allocates new OID's when needed.
2066 Raw OID's may be specified in oid_getvalbyname.
2068 YAZ now uses GNU configure to generate Makefile(s).
2070 * Minor changes in some of the member names of DeleteResultSetRequest and
2071 DeleteResultSetResponse. See include/proto.h.
2073 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2074 and added member 'languages' in TargetInfo (which was missing).
2076 Changed the way attribute sets are handled in the retrieval
2077 module. These are now cached, just like the abstract syntaxes
2080 Changed YAZ so that it links with compiled ASN.1.
2082 Added Explain-schema definitions and mapping routines. The following
2083 Explain categories have been implemented: AttributeDetails,
2084 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2086 Fixed minor bug in Windows version of Server Library.
2088 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2090 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2092 Added EXTERNAL: UNIverse Resource Report (non-standard).
2094 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2095 ENUMERATED and SET OF.
2097 * Added 'const' to some of the char pointer arguments for the
2098 functions, data1_read_node, data1_getelementbytagname,
2099 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2102 Fixed bug in data1_insert_taggeddata - the last_child member of
2103 parent wasn't initialised.
2105 * Changed data1_read_record and data1_read_node so that the supplied
2106 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2107 doesn't refer to any parts of the "SGML"-buffer.
2109 Fixed bug in server library (Windows version of statserv_remove).
2111 * Changed code so that it compiles as C++. The type definition
2112 of Odr_fun which is a member of Odr_arm was changed. The result is,
2113 that an explicit typecast is needed for the fun pointer when
2114 using Odr_arm - as in:
2115 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2117 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2119 Implemented the new structured date and time definition as approved
2120 by the ZIG. Added schemaId element to the specificTag in Espec-1
2121 (also approved at the last ZIG). Thanks to RVDM.
2123 Added some Object identifiers (RVDM).
2125 Changed the Update Extended Service (RVDM).
2127 Added command "refid" to client which specifies referenceId for
2128 the following requests.
2130 Implemented extended service handling for server. See ztest.c
2131 for an example as well as backend.h. New handlers are registerd
2132 in the Init handler.
2134 * Changed interface for sort in server.
2136 Added new members to statserv_options_block. It allows a server
2137 to read options from another source than just the command line. Thanks
2138 to Charles Woodfield.
2140 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2141 renamed to zboolean. Some C++ compilers complained about the name.
2143 Minor changes to gils.abs. Added index 's' (sort) on title
2144 and date/time-last-modified.
2146 --- 1.4pl2 1998/1/30
2148 Fixed bug in server library regarding inetd mode (-i). This bug
2149 was introduced by release 1.4.
2151 --- 1.4pl1 1998/1/29
2153 Added sort facility in client and backend server interface.
2155 Fixed problem with dependencies in Makefile(s).
2157 Fixed bugs for encoders/decoders of extended services and
2160 Implemented sub-tree feature for schemas. Sub-trees are
2161 referenced in *.abs-files. See explain.abs for an example
2162 of the use of this feature.
2164 Modified bib1.att; local attributes for ANY didn't include
2165 ANY itself (only affects use of the retrieval module).
2167 Fixed bug in plain SGML reader in function data1_read_node:
2168 tags with prefix "var" was incorrectly interpreted as variants.
2170 Added feature "sub-schemas" to enable references to - and definitions
2171 of - group of elements.
2173 * Removed member parent from type data1_element (in data1.h).
2175 Implemented function odr_nullval() that returns the value of
2178 * Removed member num_children from data1_node (in data1.h).
2180 Made NT service interface part of the server library. The
2181 function statserv_main uses the NT service when required and
2182 calls the statserv_start / statserv_close routines.
2184 Routine zget_SearchRequest and zget_PresentRequest fills
2185 resultSetName/Id member with "default" instead of "Default".
2187 Fixed memory leak in server. Request queue member wasn't freed.
2189 Fixed nmem_exit so that memory is freed.
2193 Revised the CCL parser utility to be thread safe.
2195 Added function, oid_ent_to_oid, to replace the function
2196 oid_getoidbyent, which is not thread safe.
2198 * Added nmem_init and nmem_exit to initialize and release
2199 NMEM resources. Function nmem_init should be called once in the
2200 initial thread before NMEM/ODR is used. statserv.c and client.c
2201 have been changed accordingly. The change was necessary to make
2202 NMEM thread safe. The NMEM memory pool is shared amongst threads
2203 in a process. Unix-based applications will still work fine without
2206 Added NT Services interface for the the Z39.50 (statserv) Server.
2207 Refer to the ztest.c source on the usage.
2209 Windows 95/NT port using MSVC5.0. Project files are included in the
2212 * Defined new 'global' handle for the retrieval (data1) system. The
2213 new handled, data1_handle, describes the state of the data1 system.
2214 This handle is passed as first argument to virtually all
2215 data1 related routines. The functions data1_create and data1_destroy
2216 creates and destroys a data1 handle respectively.
2218 Added ODR encode stream member to all backend request structures
2219 init, search, scan etc. This stream should be used to allocate all
2220 memory used for the response when thread safe operation is needed.
2222 Changed the comstack utility, cs_addstr, to be thread safe. The
2223 returned hostname string returned by the function is now part the
2226 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2227 function. The cs_straddr takes a COMSTACK handle as argument, so this
2228 function must be used after cs_create and before bind/connect.
2229 This function is thread safe.
2231 Moved test server to 'ztest' directory - generic server code still
2232 in 'server' directory.
2234 Made prefix query (pquery.c) utility thread safe.
2236 Added new function modifier YAZ_EXPORT to 'export' public DLL
2237 functions when using windows (see include/yconfig.h).
2239 Added definitions to the OID database (util/oid.c) (RVDM).
2241 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2243 Added call to ccl_rpn_delete in client program.
2245 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2246 release of RPN structure.
2248 Added support for C++, headers uses extern "C" for public definitions.
2249 With input from RVDM.
2251 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2252 Thanks to Ronald van der Meer (RVDM).
2254 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2256 Added support for private extensions to the OID database
2257 (oid_setprivateoids()). Thanks to RVDM.
2259 Added optional, physical ANY (key replication)
2261 Fixed null-reference problem in GRS-1 output filter.
2263 Proximity operator added to Prefix Query Format (PQF).
2265 In test client command "base" accepts multiple databases.
2267 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2271 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2273 Smallish bug-fixes in the new encoders/decoders (explain).
2275 Bug fixed in DeleteRequest.
2277 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2279 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2281 Added SOIF syntax (using private OID for now) to retrieval module and client.
2283 Added Update extended service.
2285 Added SearchResult-1 additional info structure.
2287 Added optional CCL (ISO8777) interpreter as separate module. Available
2290 --- 1.2 1996/6/10 (1st anniversary release)
2292 Added Summary record syntax. Lightly tested.
2294 Added OPAC record syntax. Untested.
2296 Added ResourceReport service encoders/decoders. Untested.
2298 Fixed bug in z_Unit - wrong tagging on unitSystem.
2300 Fixed bug in the DiagRecs decoder.
2302 Added options for max PDU size and session timeout to frontend-server.
2304 Added documentation of query-language parsers and other supporting utilities.
2306 [frontend-server] Added Attribute set to the bend_scanrequest API.
2308 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2309 surrogate diagnostics were generated.
2311 [retrieval] Allow multiple local values for attribute.
2313 [retrieval] Allow multiple attributes per element in .abs files. index type.
2315 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2317 --- 1.1pl2 1996/4/10
2319 Minor changes, mostly specific to Zebra's requirements (retrieval)
2323 Repaired bug in frontend server when running multiple listening
2324 endpoints in dynamic mode.
2326 z_External() now won't break if a known, ASN.1 value comes encapsulated
2327 in an octet-string. The value will pass through unmodified in an Odr_oct.
2329 Added a bit of code to the demo client to decode & display
2330 ASN.1-structured records represented in the octet-aligned branch of
2331 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2333 Added z_ext_getentbyref() to the ASN module. Doc updated.
2335 * Completed the SCAN definition in the ASN module. This may break SCAN
2336 code based on older YAZ-versions at compile-time. The fix is easy -
2339 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2340 under the SCAN definition. Remember to initialize this, server-people.
2342 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2343 that this does not extend to ODR and ASN.
2345 Comstack allows insertion of established socket (primarily for
2346 inetd-operation of servers). Doc updated.
2348 Front-end server can now start from the inetd in TCP mode. Doc
2351 --- 1.0pl4 1996/1/24
2355 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2356 the rank and record number.
2358 Adjustments to the frontend server.
2360 Fixed diagnostic BER dumper. It ignored the file argument.
2364 Various changes to retrieval module.
2366 Changed the union discriminators of the protocol files from enums to
2367 ints paired with #defines.
2369 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2372 *Changed operator in the RPN structure to 'roperator', again to avoid a
2375 Fixed problems in Explain decoders/encoders.
2377 --- 1.0pl2 1995/12/6
2379 Memory bug in log module fixed.
2381 --- 1.0pl1 1995/12/5
2383 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2385 Bug in Explain DatabaseInfo module fixed.
2387 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2391 The shift to v1.0 signals that we now consider the *core* functionality
2392 of YAZ reasonably stable (the core being more or less equivalent to
2393 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2394 tested (Explain not at all - though that will happen soonish).
2396 Minor changes to code to support Windows port.
2398 Various minor changes after we're getting to use GRS-1 & co. more.
2400 Added Espec-1 format.
2402 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2403 of the protocol and it cannot be selected when encoding (maps into 'string'
2404 when decoding). Needed to talk to some servers.
2406 Demo client can request simple element set names.
2408 Added Diagnostic Format encoders/decoders.
2410 Added simple Close handling to frontend server (no hooks for resource
2411 reporting yet), and demonstration client.
2413 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2415 --- 1.0b3 1995/08/24
2417 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2418 handled incorrectly when records were requested in the searchResponse. This
2419 will only affect you if you use the frontend-server.
2421 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2422 Test-client will ask for and print GRS1. Ztest will return dummy records
2425 Added Explain encoders/decoders to the service-level API. Untested.
2427 Added Extended Services: Item Order encoders and decoders to the Service-
2428 level API. Untested. We could use a recent copy of the pertinent bits
2429 of the ILL protocol to add those bits.
2431 Added diagnostic format 1 encoders/decoders to the service-level API.
2434 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2435 odr_cons.c, which causes a more correct output.
2437 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2438 was always set to 0 when no records were requested in the searchRequest.
2440 * Added better external-handling. This shouldn't harm old code that
2441 *encodes* externals. It can break code that looks for a
2442 'single-ASN1-type' representation, since those types that are known
2443 are now decoded immediately. Look at the SUTRS sample code in
2444 seshigh.c and client.c. Documentation updated.
2446 Handling of structured records in bend_fetchresponse. Length -1 marks
2447 structured record, type is deduced from format field.
2449 --- 1.0b2 1995/06/27
2450 Fairly quick maintenance release to add SUTRS support.
2452 Fixed handling of SUTRS records in the demonstration client.
2454 * Added format field to the bend_fetchrequest and bend_fetchresponce
2455 structures of the backend API (frontend server). When the record is
2456 returned, the value of the format field is mapped to an OID. The
2457 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2458 of the record. The special value VAL_NONE in the bend_request means
2459 that no specific format was requested by the client. Documentation
2460 updated accordingly. Test server (ztest) will return a fixed dummy
2461 SUTRS record if your client requests SUTRS.
2463 Documentation updated accordingly.
2465 You can now set external libraries and RANLIB support in the top-level
2469 First public release.
