1 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
4 Deprecated functions for yaz_marc-removed.
6 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
9 Branch split: YAZ_2_1_55_branch
13 Fix to ZOOM-C so that transparent reconnection is properly handled on
14 connections that are in asynchronous mode.
16 Fixed compilation on OpenBSD 4.0.
18 Large strings in GRS-1 records are now properly displayed in yaz-client.
20 Added character conversion support for "advancegreek"; based on patch from
23 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
24 sequence is met. Before the error was not set so it would be unknown.
26 Adjust yaz-marcdump MARC reader so that it skips until record separator
31 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
32 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
33 fd_set structure used as a bitmask for the FDs to be selected on.
35 Using ACX_PTHREAD macro to check for POSIX threads.
37 Fixed have-vsnprintf check.
41 Fixes for configure on BSD. Bug #900.
43 Added snprintf/vsnprintf wrappers for systems that don't have
44 limits (heavens forbid).
46 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
47 created before all previous tasks were completed and removed from the
48 task queue, the new task could be removed by a mistake.
50 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
52 Implemented pass-through CQL-to-PQF conversions. Bug #861.
54 Fixed bug #832: Problem with MARC/charset in yaz-client.
56 Fixed bug #668: save command line history for yaz-client.
58 Fixed bug #830: pkg-config support.
62 Extended ZOOM result set options with two options that may be read by
63 a client: resultSetStatus and presentStatus with values as specified for
65 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
67 Fixed bug #827: Using SSL fails on Debian etch.
69 Fixed bug #826: Weird looking chars for set of MARC records.
71 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
72 that is treated as an ItemOrder with itemRequest being an XML document
73 external. The value of "doc" is the content.
75 Extended the GFS search facility. New member of bend_search_rr
76 'estimated_hit_count' signals that hits is known to be an estmate
77 (higher or lower than real hit count). New member 'partial_resultset'
78 signals that the search was partial (hit count is lower or equal than
79 real hit count). For Z39.50, the information is stored in resultSetStatus
80 member of SearchResponse APDU. For SRU, the information is signalled
81 via SRU diagnostic 59: "Result set created with valid partial results
84 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
88 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
90 Added ZOOM_connection_peek_event.
92 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
93 the following new functions:
94 ZOOM_event_nonblock, ZOOM_connection_process,
95 ZOOM_connection_get_{socket,mask,timeout},
96 ZOOM_connection_fire_event_{timeout,socket}.
97 The existing blocking event handler, ZOOM_event, is a wrapper for the
98 + blocking ZOOM_event_sys_{poll,select}.
100 Implemented function ccl_xml_config which parses XML version of CCL
101 configuration (bug #798).
103 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
105 Added timings utility (yaz/timing.h)
107 --- 2.1.44 2007/01/03
109 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
112 Fixed bug #779: Rotation of apdu.log fails.
114 Fixed for character set conversions:
115 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
116 Honor G1 set in MARC-8 decoding.
118 --- 2.1.42 2006/12/17
120 Fixed bug #775: char conversion does not handle Alternative UTF-8
123 Implemented function yaz_marc_read_line which parses MARC line format
124 records. There is a wealth of formats out there. So far, this function
125 reads line records produced by yaz_marc_write_line.
127 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
128 more generic and easier to remember(!) options: -i format and -o format
129 which specifies input format and output format respectively - where
130 format is one of "marc", "marcxml", "line", "marcxchange".
132 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
133 does not print anything except warnings for records.
135 For yaz-marcdump, added support for MARC split into files (-s) with a given
138 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
139 spec, at http://www.loc.gov/standards/sru/record-update/
140 This has changed the binary layout of the following structs:
141 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
142 bend_update_rr . Patch by Ko van der Sloot.
144 Added GFS utility function bend_assoc_is_alive which returns 1 if
145 association is still alive (client is connected); 0 otherwise (client
146 closed connection). This allows busy servers to stop working for
149 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
150 been a separate piece of software. This version of ziffy has been modified
151 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
153 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
155 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
156 Client code may now interrogate options such as "init_opt_sort" to
157 find out whether the server claims to support various options.
159 --- 2.1.40 2006/11/27
161 Added utilities yaz_{set,get}_esn to set/get element set name from
164 Removed the build of libyazthread.la. The libyaz.so is the threaded version
165 of YAZ and has been so since YAZ 2.1.10.
167 Implemented ZOOM_record_error which returns error information for
168 record (surrogate diagnostic).
170 --- 2.1.38 2006/10/31
172 Updates for SRU Update by Ko van der Sloot:
173 1. Changed name from "operation" to "action"
174 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
175 versions in the code, marked as 'backward compatible'.
176 3. Added diagnostics for SRU Update.
178 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
180 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
182 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
184 For GFS, fixed problem with SRU diagnostic 'First record position out of
185 range' being issued for 0 hits.
187 zoomtst10 part of Windows Build.
189 --- 2.1.36 2006/10/13
191 Implemented yaz_filepath_comp which splits a path into file path
192 components (required by Zebra 2.0.3+).
194 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
195 BSD inspired license until now so this should not have any real impact on
196 anybody. See http://www.opensource.org/licenses/bsd-license.php
198 Fixed bug #687: Missing log lines.
200 Fixed bug #678: CQL to PQF translation does not preserve double-quote
203 Fixed bug #689: SRU diagnostics to be added.
205 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
206 whether a connection is idle (no more work do do).
208 --- 2.1.34 2006/10/04
210 Change type of optval from long to int for invocation of setsockopt with
211 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
213 Added support for specifying the max log file size for the Generic
214 Frontend Server. The size is given with option -r.
216 --- 2.1.32 2006/09/21
218 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
220 --- 2.1.30 2006/09/17
222 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
225 Fixed bug in Generic Frontend Server that could cause a server to stop
226 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
228 For the generic frontend server, the maximum record size is used as maximum
229 size of incoming packages (SRU + Z39.50). The value until was previously
230 only used in Z39.50 Init negotiation and, later, in a session controlled
231 sizes of records returned. This is controlled using -k option. It can be
232 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
234 --- 2.1.28 2006/09/04
236 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
239 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
241 New option for yaz-marcdump -lpos=value which allows setting a portion
242 of MARC header to a certain value.
244 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
246 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
247 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
249 --- 2.1.26 2006/08/15
251 Fixed problem with SRU mode type (soap, get, post) for yaz-client
254 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
256 --- 2.1.24 2006/08/08
258 Fixed MARC ISO2709 encoding routines to deal with character set
261 Minor changes to GFS logging. Database included in search request log
264 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
265 cached/multiple records.
267 Shared libraries are built by default on Unix+configure.
269 Changed cql2pqf transformation to use a different evaluation order. The
270 new order is: always, relation, structure, position, truncation, index
271 and relationModifier. Old order was: always, relation, relationModifier,
272 structure, index, position, truncation. Note that the the latter ones
273 override former ones for identical attributes.. The new scheme means that
274 it is possible to override any existing attribute with a relationModifier.
275 And also that it is possible to override everything for the index rule
276 (except the ones listed in relationModifier). No order is perfect but this
277 one, we believe, covers more real cases.. The "always" should have been
278 called "default", since the attributes there can be overridden with all
281 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
282 compilation phase, but also for yaz-config --cflags output. This allows
283 us to have public headers with Libxml2 stuff in them . It should also,
284 eventually, make Libxml2 checks redundant in packages using YAZ, such
287 --- 2.1.22 2006/06/15
289 Changed SRU update structure bend_update_rr so that SRU diagnostics are
290 stored in uri, message and details.. Previously diagnostics were stored
291 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
292 compatibility.. but he's probably the only one affected, so.
294 Added support for CCL, compiled on the client side, in ZOOM-C. This
295 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
296 input; the resulting query objects can be used for for searching with
297 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
299 YAZ' configure searches for OpenSSL by default.
301 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
302 SL_CTX_use_certificate_file. See
303 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
304 for more info. Thanks to Ko van der Sloot.
306 --- 2.1.20 2006/06/02
308 Bug #600: SRU GET, POST support for yaz-client. Introduced
309 command 'sru' which selects method SOAP/GET/POST.
311 Allow missingValueAction to be specified for the sortspec string -
312 function yaz_sort_spec. By default, the missing value action is null.
313 Use ! to specify "abort". Use = followed by stringvalue to specify default
316 Ensured that Present-handler (if defined) is called in GFS before any call to
317 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
318 searchRetrieve requests.
320 Documentation for YAZ is now based on the Docbook XML/XSLT using
321 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
322 is no longer depending on jade/openjade or docbook-to-man scripts.
323 PDF is no longer part of the distribution - but can optionally be
324 made using DSSSL/jadetex or FOP.
326 Added retrieval handling support in Generic Frontend Server to support
327 conversion between MARC/XML as well as XSLTtransforms. See
328 etc/yazgfs.xml for an example.
330 Added Authentication support to Generic Frontend Server in SRU
331 mode. Authentication using HTTP Basic is supported, as is the use
332 of 'x-username' and 'x-password' parameters in the request itself.
334 Added support for a new character set MARC8s identical to MARC8 except
335 that it converts combined characters to single Unicode characters in the
336 Latin-1 range (when possible).
338 --- 2.1.18 2006/04/24
340 ASN.1 compiler 0.4: generates brief Doxygen file header for
341 generated .h/.c files.
343 Utility yaz_iconv now supports conversion to MARC-8.
345 New facilities for the MARC module. The reading - and writing of
346 content are separate methods for the yaz_marc_t handle. The following
347 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
348 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
349 format). Write functions have prefix yaz_marc_write_.. The existing
350 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
351 available. Removed support for OAI-MARC and simplexml (not the
352 simplexml from PHP5).
354 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
355 to be returned for this connection.
357 --- 2.1.16 2006/03/31
359 Allow multiple languages and charsets to be specified with
360 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
361 negcharset iso-8859-1,utf-8
363 Translation of proximity nodes from CQL into PQF now works.
365 Moved to automake 1.8, 1.9.
367 Added function yaz_log_set_handler which allows a log handler to be
368 installed. This handler will be called for all log messages. Output
369 to file is also produced; but that can be disabled by passing NULL
370 fname to yaz_log_init_file.
372 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
374 For SRW (including GFS), accept application/soap+xml as content-type
377 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
378 produces NO stylesheet reference even if a default stylesheet is specified
381 --- 2.1.14 2006/03/14
383 Updated Windows package to include yazd.dll + yazd.lib for the
384 Development component.
386 If the environment variable YAZ_LOG is set, then it is used as a
387 string indicating the default level of logging to use if not
388 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
389 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
390 used as before. So, for example, to omit warnings from YAZ logging,
393 cql_transform() now map structure and other attributes before indexes,
394 so that index-specific structures and other attributes can override
395 defaults. So now a combination of mapping specifications such as:
397 index.dc.date = 1=date-modified 4=5
398 does the right thing.
400 cql_transform() now also respects the "always" mapping specification,
401 which establishes an initial set of attributes to be used for all
402 terms except where overridden by more specific attributes associated
403 with the index, relation or modifier.
405 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
406 which mode to use; one of "post", "get" or "soap" (SRW, default).
408 Fixes for yaz_iconv routines: changed trie-based character set conversions
409 to use only non-negative values for bit fields due to Sun's C compiler not
410 supporting negative values.
412 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
413 sequences where not read correctly. Fix by Rustam Usmanov.
415 Updated win/makefile to use options, settings which makes things
416 compile with VS C 2005.
418 --- 2.1.12 2006/02/01
420 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
422 In ZOOM socket code, use select instead of poll on MacOSX.
424 ZOOM-C now support client-side compilation of CQL into RPN that is
425 sent to the server, enabling CQL to be used against all Z39.50
426 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
427 ZOOM_query object, and submit it using ZOOM_connection_search().
428 The CQL-to-RPN translation uses a configuration file, the name of
429 which must be specified in the Connection's "cqlfile" option.
431 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
432 function, which takes as its start-term parameter a ZOOM_query object
433 (which may have had either CQL or RPN set into it).
436 --- 2.1.10 2005/11/29
438 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
439 GFS to support this as well. Backend handler, bend_srw_update, does the
440 update work. Code contributed by Ko van der Sloot.
442 Allow retrieval of Search Result-1 information in ZOOM by the use of
443 options that are attached to a result set. ZOOM documentation updated
446 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
447 UTF-8 conversion. Patch by Raj Patel.
449 Added option -m to GFS to control formatting of timestamps in log file.
451 Added 'exit' as synonym for 'quit' in yaz-client
453 Added support for specifying SRW resultSetId + resultSetIdleTime in a
454 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
455 for the new members. Patch by Ko van der Sloot.
457 Added support for SRU POST. It is supported for content-type
458 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
460 Do not build the separate Multi-threaded (MT) library libyazthread.la.
461 Instead make the library libyaz.la multi-threaded. Threading as a whole
462 can still be disabled by configure option --disable-threads. Previosly,
463 with older GLIBCs there were problems with MT libs under Apache. This
464 has now been fixed a long time ago.
466 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
469 CQL module modified to be case insensitive for relations/indexes/operations.
471 Fixed bug in CQL transform code: incorrect value relationModifieder
474 Added 'show all' command for yaz-client which retrieves all results
477 Added new yaz-client, xmles, which takes a (private) OID and
478 a document to be sent as an extended service request.
480 Describe new yaz-client commands wait_response and set_auto_wait.
482 Increase TCP/IP listener backlog from 3 (which I am guessing was
483 copied from the SunOS manual entry way back when) so SOMAXCONN, so
484 that the socket will queue as many incoming connections as it's able
485 to handle ongoing connections. In other words, it will never now
486 refuse a connection that it would be able to handle merely because
487 it's not got around to accepting() enough of the pending connections
488 yet. This is the behaviour anyway under Linux, where the listen()
489 argument is ignored; but not under BSD and on systems such as
490 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
491 YAZ-based servers should now be uniform across operating systems in
494 yaz-marcdump uses 64-bit file access on some systems. This is enabled
495 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
496 This allows yaz-marcdump to read large MARC batches (>2 GB).
498 Modified all YAZ source files - except the source which is auto-generated
499 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
502 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
503 corresponding to the existing *_setl() function. These allow option
504 values containing arbitrary valuues.
506 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
507 ZOOM_resultset_sort() in new applications. Its behaviour is identical
508 except that it returns an indicator of whether or not the sort
509 criterion was accepted (0 for OK, -1 for invalid).
513 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
514 MARC output rather than returning "new" buffer.
516 yaz-client warns about unknown init options.
518 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
522 Added support for SRW sort in Generic Frontend Server. Patch
523 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
524 sortKeys - or NULL if none is provided.
526 Fixed bug #307: It was impossible to specify indefinite/no timeout
527 for ZOOM_event. Special timeout value -1 now means indefinite timeout
530 Added support for multiple languages and charsets to be specified in
531 ZOOM. Each charset/language is separated by a blank. If negotiation is
532 in effect in init-response, Option
533 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
534 Code based on patch by Vasiliy Osadchuk.
536 Fixed bug #306: infinite recursion that occurred when calling
537 yaz_log_level_init as the first call (before other log level or
540 Fixed bug in scan handling in front end server: if preferred-Position-In-
541 Response was non-present, a NULL pointer referece was performed.
545 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
546 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
547 now defined for all those error codes. So instead of putting 109 in
548 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
549 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
551 Modified the yaz-marcdump utility to skip garbage bytes between MARC
554 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
556 Program yaz-client now exits and produces an error message if multiple
557 Z39.50 servers are specified on the command line (none or one allowed
560 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
565 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
567 Fixed bug #272: Preserve spacing for CCL terms.
571 Added support for virtual hosts and multiple backend servers for
572 the YAZ frontend server. The configution is XML based and
573 support specificition of CQL to RPN mappings and explain information.
574 See section "Virtual Hosts" in the YAZ manual.
576 Extended OPAC display utility. OPAC display utility renders
577 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
578 to supplement yaz_marc_decode_wrbuf.
580 Fixed a bug in MARC decoder that could caused it to crash for some
581 invalid MARC records. More diagnostics and warnings where added in
582 XML output (warnings, etc are stored in comments).
584 --- 2.0.34 2005/02/08
586 Fixes for UNIX domain sockets. Bug #261.
588 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
590 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
591 Added yaz_marc_subfield_str which defines subfield lead string which is
592 used in YAZ_MARC_LINE format. Default string is blank+$. Added
593 yaz_marc_endline_str which defines end of fields string used in
594 YAZ_MARC_LINE format. Default string is newline.
596 Experimental support for MarcXChange. This format can be produced
597 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
598 http://www.bs.dk/standards/MarcXchange.xsd
600 Added yaz-client commands scansize that sets maximum number of
601 entries to be returned by scan.
603 --- 2.0.32 2005/01/11
605 Added support for SRW scan in yaz-client and Generic Frontend Server.
607 * Added whereInList member to SRW Scan Term.
609 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
611 Fixed NMEM system to return aligned blocks on the smallest boundaries
612 that are suitably aligned for all possible types on the particular
613 architecture YAZ is being built for.
615 --- 2.0.30 2005/01/04
617 Fixed numerious warnings that was issued with newer versions of GCC.
619 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
620 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
623 Make YAZ Generic Frontend Server slightly faster.
625 Enhance (and reduce) logging for Generic Frontend Server.
627 Revert YAZ log system so that it flushes every write operation
628 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
630 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
631 instead of LOG_, due to name clash with syslog(3). LOG_ are still
632 present. New applications should define YAZ_USE_NEW_LOG=1 - this
633 will effectively disable old definitions.
635 --- 2.0.28 2004/11/09
637 Added yaz_log_time_format which specifies log format using
640 Added yaz_log_module_level which returns mask for a module. Value
641 is non-zero mask a if module is enabled; zero if disabled.
643 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
644 in include/yaz/cql.h.
646 Fixed bug #176: Dont throw diagnostics on empty SRU args.
648 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
650 Fixed bug #172: RPM builds does not enable SSL.
652 Doxyfile.in part of dist. Doxyfile generated by configure.
654 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
655 are given and the corresponding component does not exist.
657 Extend CCL documentation in YAZ reference. Describe r=r.
659 --- 2.0.26 2004/10/01
661 Fixed MARC->MARCXML conversion to properly deal with
662 fields, subfields, indicators having non-ASCII characters.
664 Fixed MARC->MARCXML conversion so that ASCII control characters
665 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
668 Added YAZ GFS support for conversion from Z39.50 surrogate
669 diagnostics to SRW surrogate diagnostics.
671 Bug fix: YAZ GFS did not return schema in explainResponse.
673 --- 2.0.25 2004/09/30
675 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
676 now converts recordSchema to elementSetName as well as schema URI.
678 Fixed bug in COMSTACK that prevented HTTP request packages from being
681 --- 2.0.24 2004/09/29
683 Added CCL facility r=r "range" which is similar to r=o "ordered" but
684 does not require white-space before and after the dash in a range, e.g.
685 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
688 Fixed a few AC_TRY_LINK configure tests that did not operate properly
689 due to new GCC removing "redundant" code.
691 Added yaz-client commands scanpos and scanstep that sets preferred
692 position and step-size for scan.
694 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
696 Added CCL utility ccl_qual_buf which parses one or more CCL
697 spec lines in a buffer.
699 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
700 of name and value - ignoring empty lines and comments.
702 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
704 Added odr_get_element_path which returns current element path for an
705 ODR handle. This utility is useful in error handling or user-defined
708 Added ODR_PRINT utility odr_set_stream which is is a more generic
709 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
710 to a write function and pointer to close function. The close function - if
711 non-NULL - will be called during odr_destroy.
713 Fixed bug in CCL parser where truncation char was not removed from
714 right side when truncation=both was in effect.
716 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
719 --- 2.0.23 2004/08/11
721 Fix buffer overrun in CQL parser when dealing with proximity (%).
723 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
724 to UTF-8/UCS conversion is now only based on codetables.xml.
726 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
728 --- 2.0.22 2004/08/06
730 Add support for more "commit changes" in ZOOM (uses Extended Services).
732 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
735 Yet another small fix for configure of SSL.
737 --- 2.0.21 2004/05/14
739 Fix SSL libs for configure when --with-openssl=DIR is given.
741 --- 2.0.20 2004/05/10
743 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
745 SSL comstack now uses yaz.pem certificate file on server side
746 by default. Certificate filename can be configured by calling
747 comstack function cs_set_ssl_certificate_file before cs_bind is used.
749 Fix bug regarding multiple calls to ZOOM_connection_connect.
751 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
753 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
754 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
756 ZOOM now allows inspection of X509 peer certificate for verification.
757 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
759 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
760 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
761 as "modular" but it simplifies things.
763 Added cs_get_peer_certificate to that returns peer X509 PEM.
765 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
766 NULL if SSL is unavailable.
768 Documentation about MARC decoding tools.
770 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
772 --- 2.0.19 2004/03/30
774 Rename CHANGELOG to NEWS to follow GNU style packing.
776 Fix bug with missing initialization of member in init_diagnostics.
777 This bug affects threaded version of GFS server.
779 --- 2.0.18 2004/03/20
781 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
784 Ensure zlib.dll is packed with Windows install.
786 --- 2.0.17 2004/03/17
788 Fix encoding of xsd:string to use text instead of CDATA.
790 Fix endless loop in CQL parser with unbalanced ".
792 Use a more compact way to store MARC-8 conversion tables.
794 --- 2.0.16 2004/03/16 Debian only
796 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
799 Update CQL parser to use new CQL 1.1 modifiers for booleans and
804 --- 2.0.15 2004/03/01
806 Another fix for decoding of XML packed records.
808 --- 2.0.14 2004/02/25
810 Fixes for Chunked encoding. White space not ignored after length spec.
812 Update NS and use default NS for SRW diagnostic elements.
814 --- 2.0.13 2004/02/23
816 Implement ZOOM_resultset_cache_reset which resets record cache.
818 Implement ZOOM_resultset_sort which sorts a result set.
820 Implement chunked HTTP transfer.
822 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
824 --- 2.0.12 2004/02/16
826 Added member 'schema' to bend_explain_rr structure so that backend
827 can specify explain record identifier. Defaults to Zeerex 2.0.
829 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
831 --- 2.0.11 2004/02/16
833 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
836 Added init command for yaz-client which sends "extra" init request.
838 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
839 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
841 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
843 Make ZOOM error code for "invalid query".
845 Fixed compilation for SSL which wasn't properly enabled for all platforms.
847 --- 2.0.10 2004/02/05
849 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
852 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
854 Added option -p <file> to make Generic Frontend Server to write PID file.
856 Added option -D to put Generic Frontend Server in background on its own.
858 Make ZOOM C recognize option "password". If unset, "pass" is used
859 (for backwards compatibility).
861 Fixed a bug in Generic Frontend Server that could make it crash if a
862 client sets characterSetNegotation bit, but didn't pass negotiation stuff
865 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
866 Must be issued before open, in order to be in effect.
868 --- 2.0.9-6 2004/01/12 Debian/Windows
870 Make the SRU server more picky WRT unknown params, etc.
872 Bug fix: ZOOM scan response didn't return displayTerm - when present.
874 New YAZ client command, options, that sets Z39.50 options.
876 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
877 options from a string of tokens (one token for each option bit).
879 Update SRW diagnostic code messages.
881 --- 2.0.9-5 2004/01/07 Debian/Windows
883 Handle user defined stylesheet for SRW/SRU.
885 --- 2.0.9-4 2004/01/06 Debian/Windows
887 Fix bug in decoding of Content-Length.
889 --- 2.0.9-3 2004/01/06 Debian/Windows
891 Fix a bug with decoding of XML packed records.
893 --- 2.0.9-2 2004/01/05 Debian only
895 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
897 Fix bug in SRW/SRU diagnostics decoding.
901 Fixed bug in Generic Frontend Server which could drop records exceeding
902 preferred message size. Reported and fixed by Irina Dijour.
904 Fixed calculation of package size for structured records in Generic
905 Frontend Server. Reported and fixed by Irina Dijour.
907 Fixed namespace for SRW/SRU diagnostics.
909 Fixed SEGV in yaz-client that occured for HTTP connection errors.
913 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
914 this version is incompatible with version 1.0 and older YAZ SRW/SRU
917 CQL changes to reflect recent changes to the specification:
918 * Documentation talks about context sets instead of index sets.
919 * Documentation talks about indexes instead of qualifiers.
920 * The CQL-to-PQF transformer's configuration file now uses
921 "index.set.name = <attributes>" instead of the old form
922 "qualifier.set.name = <attributes>". (Both forms are still
923 understood but the latter is deprecated.)
924 * CQL terms with no explicit index specified are now interpreted as
925 cql.serverChoice instead of srw.serverChoice (which of course
926 behaves exactly the same.)
930 MARC conversion can now generate ISO2709 output in another
931 character set. yaz-marcdump uses this facility if you invoke it
934 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
935 functions from there can be used from C++.
939 Frontend server now transfers memory from decoded packages to stream
942 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
943 references to show up.
945 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
946 the ZOOM Abstract API. The older names for the same options are still
947 also supported for the benefit of old applications.
949 ZOOM-C supports "implementationId" and "implementationVersion" options
950 to go along with "implementationName". These allow the user code to
951 specify identification strings to be sent to servers.
952 Add OID for the new ExtLite attribute set.
954 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
955 as requested/supplid by Ere Maijala <ere@atp.fi>
957 For generic frontend server, reverse the order of
958 "toolkit-supplied / application-supplied" strings sent as implementationId,
959 Name and Version. Also, remove the spaces around the slash. This brings
960 the GFS in line with the behaviour of ZOOM-C on the client side.
962 Add function ZOOM_scanset_display_term.
964 yaz-client shows scan displayTerm if present.
966 Utility yaz-iconv is now installed by default along with the man page
969 Extend configure check for OpenSSL to use pkg-config where available (such
972 Incorporate patch by Morten Bogeskov which allows a Unix file socket
973 server to specify uid/gid/mask for socket using the format
974 unix:[user=uid,][group=gid,][umask=mask,]file=path
975 If file= is omitted the existing format is assumed, e.g.
977 in which case the mask is 0666 (rw for everybody).
979 Major restructure of YAZ source. All source in libyaz is in src directory.
980 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
981 util (utility programs such as ASN.1 compiler, yaz-marcdump).
983 Added man page for utility yaz-marcdump (used to be called marcdump).
984 yaz-marcdump is installed by 'make install'.
986 Fixed a memory leak in Generic Frontend Server that occurred when decoding
987 of incoming package failed.
989 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
991 Change prototype of odr_perror: add const to message string.
993 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
995 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
996 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
997 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
998 DNS lookup. There should not be any compatibility problems with this
999 assuming that blocking=1 or 0 is used.
1001 Fix bad reference in UNIX comstack in function cs_addrstr.
1003 Fix for compilation on AIX.
1005 The generic front-end server (server/seshigh.c) now supports returning
1006 Init diagnostics to the client in User-information-field, in
1007 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1010 --- 2.0.4 2003/09/04
1012 Allow any CQL relation (not just all,any,exact,scr).
1014 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1015 that features the same UI.
1017 Implemented command update0 in YAZ client which is equivalent to
1018 update but uses old of Ext Update ASN.1.
1020 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1021 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1022 Previously no OID was used for this info.
1024 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1025 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1026 returns 'malformed search term' otherwise.
1028 SortResponse member resultCount now set to NULL in sort handler of
1031 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1034 Add three new utility functions for translating OIDs between various
1035 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1036 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1037 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1038 char *oid_to_dotstring(const int *oid, char *oidbuf);
1039 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1041 Reverted modifications for ES Update definition for z_IU0Update
1042 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1043 is back to YAZ 2.0.2.
1045 String value attributes for CCL parser.
1047 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1048 which their FirstSearch server returns in Init responses, sometimes
1049 carrying useful diagnostic information when Init fails. This has the
1050 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1051 "z39.50/oclcui.asn", where its definition is somewhat different from
1052 what OCLC document on their web-site, as required to interoperate with
1055 Support for anonymous authentication in yaz-client. Use the command
1058 * Fix the OID of the Index Data-local "admin" Extended Service from
1059 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1060 the 1000, which indicates a locally-defined OID, was a mistake.
1062 --- 2.0.3 2003/06/20
1064 Fix CCL directive @case handling so that it affects string match for
1065 both CCL keywords and qualifiers.
1067 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1068 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1069 Decoder has been updated with ASN.1 changes as listed in
1070 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1071 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1072 z_IUUpdate, remains unchanged.
1074 ZOOM_record_get may now return a record in a specific character set.
1075 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1076 "from" is the character set of record as returned by target. "to" is
1077 the character set to be returned. If omitted, "to" is UTF-8.
1079 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1081 New ODR utility, odr_getelement, which returns name of element for
1082 which encoding/decoding failed.
1084 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1085 in cases where a required element was omitted.
1087 Bug fix: some MARC8 sequences were not converted.
1089 New ZOOM option "step" which specifies number of records to be
1090 retrieved in one chunk. Used in conjunction with "start" and "count".
1092 SRW support for yaz-client. Use scheme http: to use it, e.g.
1095 yaz-client no longer does (un)intelligent character set conversions
1096 by default. Can be enabled with charset and marc_charset commands.
1098 xmalloc trace fix for 64-bit systems such as DEC alpha.
1100 Solaris 2.6 compile fix.
1102 New function, cql_strerror() translates SRW error codes, as returned
1103 by cql_transform_error(), into human-readable English strings. Used
1104 in yaz-client diagnostics when appropriate.
1106 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1107 converts it into a type-1 query which is sent to the server. This
1108 makes CQL available for use with all Z-servers, as opposed to the tiny
1109 minority that can handle CQL queries themselves.
1111 --- 2.0.2 2003/04/28
1113 New Debian package layout similar to the Redhat Package layout.
1115 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1116 and search result respectively.
1118 --- 2.0.1 2003/04/25
1120 Redhat package is now several packages: libyaz (runtime libraries),
1121 libyaz-devel (development and documentation, and yaz (utility programs).
1122 Package spec file by Morten Bøgeskov.
1124 New member 'schema' in struct bend_fetch_rr which the name of requested
1125 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1126 handler MAY set this to reflect the schema of the returned record.
1128 New member 'display_term' in struct scan_entry. GFS now sets member entries
1129 and allocates scan entries to be filled by user scan handler. In previous
1130 version, entries member was allocated by the scan handler. That still works,
1131 but the GFS will ignore member display_term - assuming it was NOT set by
1132 the handler. The fact that the GFS now allocates the entries both allows
1133 for new members and makes a scan handler easier to write.
1135 Fix CQL lex buffer overflow.
1137 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1138 SRU default recordPacking is string.
1140 SRU protocol support for frontend server.
1142 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1144 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1146 Added scan for the ZOOM shell (zoomsh).
1150 * String Identifers for Schemas (Amendment 5).
1151 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1152 Old definition for schema
1153 Odr_oid *schema; /* OPT */
1158 Z_InternationalString *uri;
1159 #define Z_Schema_oid 1
1160 #define Z_Schema_uri 2
1163 * resultCount parameter to Sort Response (Amendment 1).
1164 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1166 Support for SRW 1.0 over HTTP. This is an optional feature and
1167 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1170 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1171 on the same port. SRW SearchRetrieveRequests are mapped
1172 to bend_init,bend_search,bend_fetch,bend_close.
1174 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1176 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1177 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1179 ZOOM connections are SRW based if schem http is used for hostname
1180 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1181 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1183 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1184 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1185 distance=n, order=true/false, relation=le, prox unit=word. If
1186 n is omitted, distance 1 is used.
1188 Fixed problem with C compiler include path in wrong order.
1190 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1191 on Solaris. Patch from Ko van der Sloot.
1193 New MARC decode API. All new functions operate on a yaz_marc_t
1194 handle. The most important new functions are: yaz_marc_create,
1195 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1196 decode and destroy respectively. Decoder can produce formats
1197 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1198 include/yaz/marcdisp.h.
1200 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1201 to UTF-8, UCS-32, wchar_t or Latin-1.
1203 * Prototypes for yaz_iconv_-functions moved to separate header
1204 include/yaz/yaz-iconv.h.
1206 Make a few private functions 'static' in unix.c. This prevents
1207 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1209 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1210 are set when Init Response is received.
1212 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1213 but returns diagnostic set as well.
1215 New function yaz_strerror which is a portable wrapper for
1216 strerror/strerror_r/GetLastMessage.
1218 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1219 is returned for MARC. If type is "oai", then OAI MARC is returned.
1221 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1224 --- 1.9.2 2002/11/26
1226 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1228 Fix bad race conditions on SIGTERM and terminate gracefully in
1231 Move retrieval (data1) module to Zebra since nobody seems to be
1234 Add GRS-1 render for ZOOM using same format as yaz-client.
1236 --- 1.9.1 2002/10/05
1238 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1240 Fix broken ESpec handling in data1 module.
1242 SGML reader parses comments and makes them part of the data1 tree.
1244 Added several type casts so that YAZ compiles as C++ code.
1246 ZOOM didn't handle PDU encoding failures properly.
1248 Added more Bib-1 diagnostics (approved extensions).
1250 GNU configure: better check for iconv.
1252 More portable use of accept, getpeername. Check for socklen_t. Use
1253 int/size_t if socklen_t is not defined.
1257 PQF parser rejects bad queries - including those with extra
1258 characters in them. PQF parser used to silently ignore that.
1259 Cleaner API for PQF added, which allows you to get detailed
1260 error information for bad queries (see yaz/pquery.h).
1262 Fixed bug in ZOOM_record_get for type "database".
1264 Implemented mini iconv library supporting conversions between
1265 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1267 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1269 --- 1.8.9 2002/08/20
1271 Fixed ZOOM C record cache so that preferredRecordSyntax and
1272 elementSetName is used to check for already fetched records.
1274 --- 1.8.8 2002/08/02
1276 Added three members in bend_initrequest structure to facilitate
1277 character set negotiation.
1279 Fixed a bug in frontend server that could cause indefinite
1280 loops under rare conditions.
1282 Revised character set utilities (charneg.h) so that encoding
1283 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1285 For PQF, directive @term <type> sets term type for Scan/Search.
1286 Here <type> is general, string, numeric, null. The term type
1287 is inherited - just like @attr.
1289 New call odr_set_charset that sets character set conversion for
1290 international-strings on a ODR stream. Prototype is:
1291 int odr_set_charset(ODR o, const char *to, const char *from);
1292 The InternationalString is still represented as C string in YAZ
1293 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1294 won't). On the protocol level, you can use any encoding.
1296 Support for UNIX sockets in ZOOM.
1298 Solaris recv sometimes returns errno == ENOENT. It is treated as
1299 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1301 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1302 both client and server. Code by Morten Bøgeskov.
1304 --- 1.8.7 2002/05/22
1306 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1307 that they can be used directly from Visual Basic. You must recompile
1308 your windows APP if you're using ZOOM.
1310 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1311 Commands "lang" and "charset" sets language and character set respectively.
1312 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1313 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1315 Attributes from multiple CCL fields may be OR'ed rather than merged
1316 using directive "@field or". Fields are still merged by default -
1317 equivalent to "@field merge".
1319 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1322 Fixed bug in zget for parameter ExtendedServicesResponse.
1326 --- 1.8.6 2002/03/25
1328 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1330 Client displays USR.1:SearchResult-1 (hits per term).
1332 Additional Search Info for search in Generic Frontend Server.
1334 Fixed CCL parsing of "field=s".
1336 WIN32 installer - using the excellent NSIS software from nullsoft.
1338 Fixed CCL parsing of "field = - <number>".
1340 Added function yaz_marc_decode that decodes MARC for line mode
1341 display or XML (similar to that used by JZKit).
1343 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1344 Z39.50. But ISO/ILL was, however.
1346 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1347 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1350 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1352 --- 1.8.5 2002/02/03
1354 New YAZ client features: Command completion and new commands:
1355 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1356 Code provided by Jacob Poulsen.
1358 New call oid_trav, that visits all registered OIDs via callback.
1360 Function ZOOM_record_get now returns const char pointer rather than
1361 void pointer. It saves a lot of type casts.
1363 For YAZ client, command "auth" now allows you to set authentication
1364 in IdPass style. It is enabled when three tokens are given - order
1365 is user, group and password.
1367 Fix memory leaks in MARC record handling for ZOOM.
1369 New option for YAZ client, -k <kilobytes> that sets
1370 maximum record size. Similar to -k option for generic frontend
1371 server and yaz-ztest.
1373 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1375 Prefix query parser reports "fail" when bad attribute set is given.
1377 Fix in MARC decoder. Proximity logging. Fix for attribute set
1378 in scan handler for server. Patches by Shigeru Ishida.
1380 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1383 Configure option --with-openssl=<dir> now works when a directory is
1384 specified. Patch provided by Morten Bøgeskov.
1386 New option for YAZ client, -u <auth>, that sets authentication.
1388 ZOOM fix: error information was sometimes "missing", since error
1389 was cleared/reset too when it shouldn't.
1391 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1393 --- 1.8.4 2002/01/04
1395 Scan for ZOOM API. New object ZOOM_scanset. New functions
1396 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1397 ZOOM_scanset_destroy.
1399 New ZOOM function, ZOOM_connection_last_event, that returns type
1400 of last event (such as "receive data", "send data", "apdu received",
1403 New ZOOM option, schema, that specifies schema for retrieval.
1405 New CCL feature. Qualifiers can be aliases for one or more
1406 other qualifiers (if more than one is given, OR is used).
1408 ZOOM uses named result sets if target supports it.
1410 Two new YAZ client commands: . (dot, which sources a script of YAZ
1411 client commands), and ! (to execute shell command.). Implemented
1414 Working on Debian packages.
1416 --- 1.8.3 2001/11/19
1418 YAZ client enables named result sets only if target supports it.
1420 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1422 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1423 with key="host" to get same result.
1425 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1426 Function Z3950_resultset_record(s) returns references to records
1427 "owned" by resultset. To become owner use Z3950_record_clone.
1429 Function z_ext_record handles Extended Services. Thanks to
1432 --- 1.8.2 2001/11/12
1434 CCL Parser fix: ignore token comma when dealing with and-lists.
1436 Documentation updates for COMSTACK.
1438 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1439 Changed prototype Z3950_records. For some functions, int parameters
1440 were changed to size_t.
1442 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1445 New MARC decode/display function, marc_display_exl, which properly rejects
1446 non-ISO2709 records. YAZ client uses it.
1448 --- 1.8.1 2001/10/29
1450 Fix bug: local attribute set wasn't set correctly in PQF strings.
1454 * Old Z39.50 codecs no longer supported.
1456 Added ZOOM C binding. See http://zoom.z3950.org/
1458 Renamed states for COMSTACKs to avoid confusion with events.
1460 Implemented cs_look and proper cs_rcvconnect.
1462 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1464 Configure detects POSIX threads on OpenBSD.
1466 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1467 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1469 When error is returned from present handler, non-surrogate diagnostic
1470 is returned in present response (and fetch handler is no longer called).
1472 * Minor adjustments to pquery parser (PQF). Token characters may be
1473 escaped by using backslash (C-style).
1475 PQF parser allows string attribute values to be specified. For @attr,
1476 non-numeric characters after the equal-sign are treated as strings
1477 (e.g. @attr 9=title).
1479 CCL trunction character may be defined (@truncation in file)
1481 * function zget_ExtendedServicesRequest sets waitAction to
1482 waitIfPossible (was wait).
1484 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1487 CCL operator names may be set in field definition files (CCL_bibset).
1488 See ccl/bib1 for an example.
1490 Fixes in ASN.1 compiler for C++ compatibility.
1492 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1493 and "op_or" to avoid conflict with C++.
1495 Fixed problem with GNU readline detection on Redhat 7.0.
1497 Added step-size for Scan backend handler.
1499 Fixed bug that made the frontend server crash when no attribute
1500 set was specified for scan.
1502 Front-end server automatically switches to original working directory
1503 when installed as an NT service. Previously -w had to be specified to
1506 Added extended attributes for retrieval module (data1), so that data1
1507 records carry d1_readXML/SGML attributes. d1_read also supports
1508 null-data rules ( <tag/>)
1510 On UNIX when POSIX threads are available, a separate library libyazthread
1511 is created. Programmers should link with that library and the yaz library
1512 when using threads. The reason for the split was that some applications
1513 on Linux, such as Apache, doesn't work well when using shared objects that
1516 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1517 (or any frontend server) in SSL mode by specifying ssl: followed by
1518 address. Only tested on UNIX.
1520 Added feature for CCL module. Virtual structure s=al or s=ol generates
1521 and-list and or-list respectively instead of phrase search.
1525 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1526 log_mask_str. This was done to avoid name conflicts with other libraries
1527 (such as other PHP extensions).
1529 Added raw OID member for preferred record syntax (request_format_raw)
1530 and returned record syntax (output_format_raw) for backend fetch method.
1532 Config file yaz-config now accepts options so that it returns specific
1533 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1535 Shared library support for UNIX using GNU libtool.
1537 * Modified backend interface. Request/Response struct's replaced by
1538 one read/write C struct. For example bend_fetchrequest and
1539 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1540 Every handler - even search has to be registered in bend_init
1541 handler. This means that the YAZ library no longer refers to
1542 external functions and it makes it possible to make the whole
1543 thing a single DLL/SO.
1545 Added Segment handler for backend server.
1547 Added Zmbol/Zebra administrative functions to YAZ client.
1549 Threaded frontend server on UNIX (when POSIX Threads are available).
1550 Starting the server with option -T enables multi-threading.
1554 Added configure option --enable-comp/disable-comp to control use
1555 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1556 located in sub directory asn.
1558 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1559 in ${exec_prefix}/bin along with the other programs yaz-client and
1562 GNU automake used to maintain makefiles.
1564 Added several OID's.
1566 Changed retrieval module so that we can load records with no abstract
1567 syntax defined. Tagpaths in these records are fully composed of string
1570 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1574 On UNIX, the generated makefile now supports a proper 'make install'.
1575 The prefix can be set via GNU configure to set the install location
1576 (default is /usr/local).
1578 * YAZ programs client and ztest were renamed to yaz-client and
1579 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1580 locations, such as /usr/bin,/usr/local/bin,etc.
1582 * YAZ Header files were moved from include to include/yaz. YAZ Header
1583 files are referred to as include <yaz/log.h> rather than <log.h>.
1584 The YAZ include path (-I ..) is therefore the same as before. Programmers
1585 should update their #include statements or use -Ipath/include/yaz
1586 instead. The main motivation for doing this change is that YAZ header files
1587 can be installed in "standard" locations /usr/include,/usr/local/include
1588 without introducing conflicts, since ALL YAZ header files are stored
1589 in subdirectory yaz (under /usr/include for example).
1591 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1592 rather than project/workspace files. We switched because project files
1593 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1596 Changed name of logging function, logf, to yaz_log, to prevent name
1597 clash with some math-log functions. The YAZ header log.h defines logf
1598 to yaz_log (#define) so there should be no incompatibilities by this
1601 Added bend_start/bend_stop handlers for server. These handler are
1602 called on start/stop of server. For windows they are called whenever
1603 a service is started/stopped.
1605 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1606 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1607 in util/yc.tcl. The auto-generated C code structures are, in a few
1608 cases, incompatible with the old decoders. There are differences in the
1609 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1610 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1611 The preprocessor variable ASN_COMPILED is defined when the compiled
1612 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1613 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1614 wish to use the old encoders/decoders you can specify --disable-yc
1617 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1618 version so that it supports both new - and old version of DB Update
1620 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1621 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1622 change. The name parameter can be set to 0 in which no name is specified
1623 for the construction. The macros odr_implicit and odr_explicit sets name
1624 parameter to zero for the construction involved. New macros
1625 odr_implicit_tag and odr_explicit_tag are similar to the others,
1626 except that a name parameter is added. For programmers' that don't use
1627 ODR they probably only need to change the call to z_APDU and z_External.
1629 Added access control facility by interfacing the TCP wrapper library.
1630 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1631 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1632 name of the daemon and enables the access control as specified in
1633 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1635 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1636 den Dool <H.M.vdnDool@kub.nl>.
1638 Added reference ID parameter to most functions in server API - refer
1639 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1641 Changed name of ccl library to libccl.a (was ccl.a).
1643 Fixed bug in decoder for Explain (Category TargetInfo).
1645 Added support for GNU readline in client. Thanks to Jacob Poulsen
1646 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1648 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1649 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1650 IMPLEMENTATION! This change was made to the development version before
1651 the ZIG decided to retract the amendment. If any users MUST be
1652 compatible with the original Update definition, PLEASE CONTACT US, and
1653 we will include a separate definition corresponding to the old Update
1654 ES. Note that because of the change to the ASN.1 of the
1655 TaskPackageRecordStructure we cannot define a single structure that
1656 will support both versions.
1658 * Added const modifier to buffer parameter for some ODR/BER encoding
1659 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1660 completeWAIS, odr_dumpBER.
1662 Fixed bug in client.c which caused a crash when a scanResponse didn't
1663 contain positionOfTerm.
1665 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1666 * will cause an error in a client if a non-YAZ target sends both a
1667 * list of Scan entries and non-surrogate diagnostics.
1669 Retrieval module enhancements. Tag sets may be typed in the reference
1670 to it. From the .abs-file the "tagset" directive takes a third optional
1671 integer type for the tag set referenced. From a .tag-file the "include"
1672 directive takes a third optional type as well. The old "type" directive
1673 in the tag set itself is still recognized but acts as the default type
1676 Backend interface change. Individual Scan terms returned from bend_scan
1677 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1678 in include/backend.h.
1680 Retrieval module enhancements. Multiple tag sets and attribute sets may
1681 be specified in abstract syntax specs. Revised the error/warning for
1682 logging messages reported by the retrieval module when reading the
1685 Object Identifier system (oid_..) changed. The API is backwards
1686 compatible but the oid-routines now allocates new OID's when needed.
1687 Raw OID's may be specified in oid_getvalbyname.
1689 YAZ now uses GNU configure to generate Makefile(s).
1691 * Minor changes in some of the member names of DeleteResultSetRequest and
1692 DeleteResultSetResponse. See include/proto.h.
1694 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1695 and added member 'languages' in TargetInfo (which was missing).
1697 Changed the way attribute sets are handled in the retrieval
1698 module. These are now cached, just like the abstract syntaxes
1701 Changed YAZ so that it links with compiled ASN.1.
1703 Added Explain-schema definitions and mapping routines. The following
1704 Explain categories have been implemented: AttributeDetails,
1705 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1707 Fixed minor bug in Windows version of Server Library.
1709 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1711 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1713 Added EXTERNAL: UNIverse Resource Report (non-standard).
1715 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1716 ENUMERATED and SET OF.
1718 * Added 'const' to some of the char pointer arguments for the
1719 functions, data1_read_node, data1_getelementbytagname,
1720 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1723 Fixed bug in data1_insert_taggeddata - the last_child member of
1724 parent wasn't initialised.
1726 * Changed data1_read_record and data1_read_node so that the supplied
1727 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1728 doesn't refer to any parts of the "SGML"-buffer.
1730 Fixed bug in server library (Windows version of statserv_remove).
1732 * Changed code so that it compiles as C++. The type definition
1733 of Odr_fun which is a member of Odr_arm was changed. The result is,
1734 that an explicit typecast is needed for the fun pointer when
1735 using Odr_arm - as in:
1736 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1738 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1740 Implemented the new structured date and time definition as approved
1741 by the ZIG. Added schemaId element to the specificTag in Espec-1
1742 (also approved at the last ZIG). Thanks to RVDM.
1744 Added some Object identifiers (RVDM).
1746 Changed the Update Extended Service (RVDM).
1748 Added command "refid" to client which specifies referenceId for
1749 the following requests.
1751 Implemented extended service handling for server. See ztest.c
1752 for an example as well as backend.h. New handlers are registerd
1753 in the Init handler.
1755 * Changed interface for sort in server.
1757 Added new members to statserv_options_block. It allows a server
1758 to read options from another source than just the command line. Thanks
1759 to Charles Woodfield.
1761 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1762 renamed to zboolean. Some C++ compilers complained about the name.
1764 Minor changes to gils.abs. Added index 's' (sort) on title
1765 and date/time-last-modified.
1767 --- 1.4pl2 1998/1/30
1769 Fixed bug in server library regarding inetd mode (-i). This bug
1770 was introduced by release 1.4.
1772 --- 1.4pl1 1998/1/29
1774 Added sort facility in client and backend server interface.
1776 Fixed problem with dependencies in Makefile(s).
1778 Fixed bugs for encoders/decoders of extended services and
1781 Implemented sub-tree feature for schemas. Sub-trees are
1782 referenced in *.abs-files. See explain.abs for an example
1783 of the use of this feature.
1785 Modified bib1.att; local attributes for ANY didn't include
1786 ANY itself (only affects use of the retrieval module).
1788 Fixed bug in plain SGML reader in function data1_read_node:
1789 tags with prefix "var" was incorrectly interpreted as variants.
1791 Added feature "sub-schemas" to enable references to - and definitions
1792 of - group of elements.
1794 * Removed member parent from type data1_element (in data1.h).
1796 Implemented function odr_nullval() that returns the value of
1799 * Removed member num_children from data1_node (in data1.h).
1801 Made NT service interface part of the server library. The
1802 function statserv_main uses the NT service when required and
1803 calls the statserv_start / statserv_close routines.
1805 Routine zget_SearchRequest and zget_PresentRequest fills
1806 resultSetName/Id member with "default" instead of "Default".
1808 Fixed memory leak in server. Request queue member wasn't freed.
1810 Fixed nmem_exit so that memory is freed.
1814 Revised the CCL parser utility to be thread safe.
1816 Added function, oid_ent_to_oid, to replace the function
1817 oid_getoidbyent, which is not thread safe.
1819 * Added nmem_init and nmem_exit to initialize and release
1820 NMEM resources. Function nmem_init should be called once in the
1821 initial thread before NMEM/ODR is used. statserv.c and client.c
1822 have been changed accordingly. The change was necessary to make
1823 NMEM thread safe. The NMEM memory pool is shared amongst threads
1824 in a process. Unix-based applications will still work fine without
1827 Added NT Services interface for the the Z39.50 (statserv) Server.
1828 Refer to the ztest.c source on the usage.
1830 Windows 95/NT port using MSVC5.0. Project files are included in the
1833 * Defined new 'global' handle for the retrieval (data1) system. The
1834 new handled, data1_handle, describes the state of the data1 system.
1835 This handle is passed as first argument to virtually all
1836 data1 related routines. The functions data1_create and data1_destroy
1837 creates and destroys a data1 handle respectively.
1839 Added ODR encode stream member to all backend request structures
1840 init, search, scan etc. This stream should be used to allocate all
1841 memory used for the response when thread safe operation is needed.
1843 Changed the comstack utility, cs_addstr, to be thread safe. The
1844 returned hostname string returned by the function is now part the
1847 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1848 function. The cs_straddr takes a COMSTACK handle as argument, so this
1849 function must be used after cs_create and before bind/connect.
1850 This function is thread safe.
1852 Moved test server to 'ztest' directory - generic server code still
1853 in 'server' directory.
1855 Made prefix query (pquery.c) utility thread safe.
1857 Added new function modifier YAZ_EXPORT to 'export' public DLL
1858 functions when using windows (see include/yconfig.h).
1860 Added definitions to the OID database (util/oid.c) (RVDM).
1862 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1864 Added call to ccl_rpn_delete in client program.
1866 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1867 release of RPN structure.
1869 Added support for C++, headers uses extern "C" for public definitions.
1870 With input from RVDM.
1872 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1873 Thanks to Ronald van der Meer (RVDM).
1875 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.

1878 (oid_setprivateoids()). Thanks to RVDM.
1880 Added optional, physical ANY (key replication)
1882 Fixed null-reference problem in GRS-1 output filter.
1884 Proximity operator added to Prefix Query Format (PQF).
1886 In test client command "base" accepts multiple databases.
1888 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1892 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1894 Smallish bug-fixes in the new encoders/decoders (explain).
1896 Bug fixed in DeleteRequest.
1898 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1900 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1902 Added SOIF syntax (using private OID for now) to retrieval module and client.
1904 Added Update extended service.
1906 Added SearchResult-1 additional info structure.
1908 Added optional CCL (ISO8777) interpreter as separate module. Available
1911 --- 1.2 1996/6/10 (1st anniversary release)
1913 Added Summary record syntax. Lightly tested.
1915 Added OPAC record syntax. Untested.
1917 Added ResourceReport service encoders/decoders. Untested.
1919 Fixed bug in z_Unit - wrong tagging on unitSystem.

1929 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1930 surrogate diagnostics were generated.
1932 [retrieval] Allow multiple local values for attribute.
1934 [retrieval] Allow multiple attributes per element in .abs files. index type.
1936 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1938 --- 1.1pl2 1996/4/10
1940 Minor changes, mostly specific to Zebra's requirements (retrieval)
1944 Repaired bug in frontend server when running multiple listening
1945 endpoints in dynamic mode.
1947 z_External() now won't break if a known, ASN.1 value comes encapsulated
1948 in an octet-string. The value will pass through unmodified in an Odr_oct.
1950 Added a bit of code to the demo client to decode & display
1951 ASN.1-structured records represented in the octet-aligned branch of
1952 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1954 Added z_ext_getentbyref() to the ASN module. Doc updated.
1956 * Completed the SCAN definition in the ASN module. This may break SCAN
1957 code based on older YAZ-versions at compile-time. The fix is easy -
1960 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1961 under the SCAN definition. Remember to initialize this, server-people.
1963 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1964 that this does not extend to ODR and ASN.
1966 Comstack allows insertion of established socket (primarily for
1967 inetd-operation of servers). Doc updated.
1969 Front-end server can now start from the inetd in TCP mode. Doc
1972 --- 1.0pl4 1996/1/24
1976 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1977 the rank and record number.
1979 Adjustments to the frontend server.
1981 Fixed diagnostic BER dumper. It ignored the file argument.
1985 Various changes to retrieval module.
1987 Changed the union discriminators of the protocol files from enums to
1988 ints paired with #defines.
1990 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1993 *Changed operator in the RPN structure to 'roperator', again to avoid a
1996 Fixed problems in Explain decoders/encoders.
1998 --- 1.0pl2 1995/12/6
2000 Memory bug in log module fixed.
2002 --- 1.0pl1 1995/12/5
2004 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2006 Bug in Explain DatabaseInfo module fixed.
2008 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2012 The shift to v1.0 signals that we now consider the *core* functionality
2013 of YAZ reasonably stable (the core being more or less equivalent to
2014 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2015 tested (Explain not at all - though that will happen soonish).
2017 Minor changes to code to support Windows port.
2019 Various minor changes after we're getting to use GRS-1 & co. more.
2021 Added Espec-1 format.
2023 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2024 of the protocol and it cannot be selected when encoding (maps into 'string'
2025 when decoding). Needed to talk to some servers.
2027 Demo client can request simple element set names.
2029 Added Diagnostic Format encoders/decoders.
2031 Added simple Close handling to frontend server (no hooks for resource
2032 reporting yet), and demonstration client.
2034 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2036 --- 1.0b3 1995/08/24
2038 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2039 handled incorrectly when records were requested in the searchResponse. This
2040 will only affect you if you use the frontend-server.
2042 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2043 Test-client will ask for and print GRS1. Ztest will return dummy records
2046 Added Explain encoders/decoders to the service-level API. Untested.
2048 Added Extended Services: Item Order encoders and decoders to the Service-
2049 level API. Untested. We could use a recent copy of the pertinent bits
2050 of the ILL protocol to add those bits.
2052 Added diagnostic format 1 encoders/decoders to the service-level API.
2055 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2056 odr_cons.c, which causes a more correct output.
2058 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2059 was always set to 0 when no records were requested in the searchRequest.
2061 * Added better external-handling. This shouldn't harm old code that
2062 *encodes* externals. It can break code that looks for a
2063 'single-ASN1-type' representation, since those types that are known
2064 are now decoded immediately. Look at the SUTRS sample code in
2065 seshigh.c and client.c. Documentation updated.
2067 Handling of structured records in bend_fetchresponse. Length -1 marks
2068 structured record, type is deduced from format field.
2070 --- 1.0b2 1995/06/27
2071 Fairly quick maintenance release to add SUTRS support.
2073 Fixed handling of SUTRS records in the demonstration client.
2075 * Added format field to the bend_fetchrequest and bend_fetchresponce
2076 structures of the backend API (frontend server). When the record is
2077 returned, the value of the format field is mapped to an OID. The
2078 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2079 of the record. The special value VAL_NONE in the bend_request means
2080 that no specific format was requested by the client. Documentation
2081 updated accordingly. Test server (ztest) will return a fixed dummy
2082 SUTRS record if your client requests SUTRS.
2084 Documentation updated accordingly.
2086 You can now set external libraries and RANLIB support in the top-level
2090 First public release.
