1 Branch split: YAZ_2_1_55_branch
5 Fix to ZOOM-C so that transparent reconnection is properly handled on
6 connections that are in asynchronous mode.
8 Fixed compilation on OpenBSD 4.0.
10 Large strings in GRS-1 records are now properly displayed in yaz-client.
12 Added character conversion support for "advancegreek"; based on patch from
15 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
16 sequence is met. Before the error was not set so it would be unknown.
18 Adjust yaz-marcdump MARC reader so that it skips until record separator
23 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
24 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
25 fd_set structure used as a bitmask for the FDs to be selected on.
27 Using ACX_PTHREAD macro to check for POSIX threads.
29 Fixed have-vsnprintf check.
33 Fixes for configure on BSD. Bug #900.
35 Added snprintf/vsnprintf wrappers for systems that don't have
36 limits (heavens forbid).
38 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
39 created before all previous tasks were completed and removed from the
40 task queue, the new task could be removed by a mistake.
42 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
44 Implemented pass-through CQL-to-PQF conversions. Bug #861.
46 Fixed bug #832: Problem with MARC/charset in yaz-client.
48 Fixed bug #668: save command line history for yaz-client.
50 Fixed bug #830: pkg-config support.
54 Extended ZOOM result set options with two options that may be read by
55 a client: resultSetStatus and presentStatus with values as specified for
57 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
59 Fixed bug #827: Using SSL fails on Debian etch.
61 Fixed bug #826: Weird looking chars for set of MARC records.
63 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
64 that is treated as an ItemOrder with itemRequest being an XML document
65 external. The value of "doc" is the content.
67 Extended the GFS search facility. New member of bend_search_rr
68 'estimated_hit_count' signals that hits is known to be an estmate
69 (higher or lower than real hit count). New member 'partial_resultset'
70 signals that the search was partial (hit count is lower or equal than
71 real hit count). For Z39.50, the information is stored in resultSetStatus
72 member of SearchResponse APDU. For SRU, the information is signalled
73 via SRU diagnostic 59: "Result set created with valid partial results
76 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
80 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
82 Added ZOOM_connection_peek_event.
84 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
85 the following new functions:
86 ZOOM_event_nonblock, ZOOM_connection_process,
87 ZOOM_connection_get_{socket,mask,timeout},
88 ZOOM_connection_fire_event_{timeout,socket}.
89 The existing blocking event handler, ZOOM_event, is a wrapper for the
90 + blocking ZOOM_event_sys_{poll,select}.
92 Implemented function ccl_xml_config which parses XML version of CCL
93 configuration (bug #798).
95 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
97 Added timings utility (yaz/timing.h)
101 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
104 Fixed bug #779: Rotation of apdu.log fails.
106 Fixed for character set conversions:
107 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
108 Honor G1 set in MARC-8 decoding.
110 --- 2.1.42 2006/12/17
112 Fixed bug #775: char conversion does not handle Alternative UTF-8
115 Implemented function yaz_marc_read_line which parses MARC line format
116 records. There is a wealth of formats out there. So far, this function
117 reads line records produced by yaz_marc_write_line.
119 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
120 more generic and easier to remember(!) options: -i format and -o format
121 which specifies input format and output format respectively - where
122 format is one of "marc", "marcxml", "line", "marcxchange".
124 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
125 does not print anything except warnings for records.
127 For yaz-marcdump, added support for MARC split into files (-s) with a given
130 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
131 spec, at http://www.loc.gov/standards/sru/record-update/
132 This has changed the binary layout of the following structs:
133 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
134 bend_update_rr . Patch by Ko van der Sloot.
136 Added GFS utility function bend_assoc_is_alive which returns 1 if
137 association is still alive (client is connected); 0 otherwise (client
138 closed connection). This allows busy servers to stop working for
141 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
142 been a separate piece of software. This version of ziffy has been modified
143 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
145 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
147 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
148 Client code may now interrogate options such as "init_opt_sort" to
149 find out whether the server claims to support various options.
151 --- 2.1.40 2006/11/27
153 Added utilities yaz_{set,get}_esn to set/get element set name from
156 Removed the build of libyazthread.la. The libyaz.so is the threaded version
157 of YAZ and has been so since YAZ 2.1.10.
159 Implemented ZOOM_record_error which returns error information for
160 record (surrogate diagnostic).
162 --- 2.1.38 2006/10/31
164 Updates for SRU Update by Ko van der Sloot:
165 1. Changed name from "operation" to "action"
166 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
167 versions in the code, marked as 'backward compatible'.
168 3. Added diagnostics for SRU Update.
170 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
172 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
174 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
176 For GFS, fixed problem with SRU diagnostic 'First record position out of
177 range' being issued for 0 hits.
179 zoomtst10 part of Windows Build.
181 --- 2.1.36 2006/10/13
183 Implemented yaz_filepath_comp which splits a path into file path
184 components (required by Zebra 2.0.3+).
186 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
187 BSD inspired license until now so this should not have any real impact on
188 anybody. See http://www.opensource.org/licenses/bsd-license.php
190 Fixed bug #687: Missing log lines.
192 Fixed bug #678: CQL to PQF translation does not preserve double-quote
195 Fixed bug #689: SRU diagnostics to be added.
197 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
198 whether a connection is idle (no more work do do).
200 --- 2.1.34 2006/10/04
202 Change type of optval from long to int for invocation of setsockopt with
203 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
205 Added support for specifying the max log file size for the Generic
206 Frontend Server. The size is given with option -r.
208 --- 2.1.32 2006/09/21
210 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
212 --- 2.1.30 2006/09/17
214 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
217 Fixed bug in Generic Frontend Server that could cause a server to stop
218 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
220 For the generic frontend server, the maximum record size is used as maximum
221 size of incoming packages (SRU + Z39.50). The value until was previously
222 only used in Z39.50 Init negotiation and, later, in a session controlled
223 sizes of records returned. This is controlled using -k option. It can be
224 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
226 --- 2.1.28 2006/09/04
228 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
231 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
233 New option for yaz-marcdump -lpos=value which allows setting a portion
234 of MARC header to a certain value.
236 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
238 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
239 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
241 --- 2.1.26 2006/08/15
243 Fixed problem with SRU mode type (soap, get, post) for yaz-client
246 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
248 --- 2.1.24 2006/08/08
250 Fixed MARC ISO2709 encoding routines to deal with character set
253 Minor changes to GFS logging. Database included in search request log
256 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
257 cached/multiple records.
259 Shared libraries are built by default on Unix+configure.
261 Changed cql2pqf transformation to use a different evaluation order. The
262 new order is: always, relation, structure, position, truncation, index
263 and relationModifier. Old order was: always, relation, relationModifier,
264 structure, index, position, truncation. Note that the the latter ones
265 override former ones for identical attributes.. The new scheme means that
266 it is possible to override any existing attribute with a relationModifier.
267 And also that it is possible to override everything for the index rule
268 (except the ones listed in relationModifier). No order is perfect but this
269 one, we believe, covers more real cases.. The "always" should have been
270 called "default", since the attributes there can be overridden with all
273 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
274 compilation phase, but also for yaz-config --cflags output. This allows
275 us to have public headers with Libxml2 stuff in them . It should also,
276 eventually, make Libxml2 checks redundant in packages using YAZ, such
279 --- 2.1.22 2006/06/15
281 Changed SRU update structure bend_update_rr so that SRU diagnostics are
282 stored in uri, message and details.. Previously diagnostics were stored
283 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
284 compatibility.. but he's probably the only one affected, so.
286 Added support for CCL, compiled on the client side, in ZOOM-C. This
287 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
288 input; the resulting query objects can be used for for searching with
289 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
291 YAZ' configure searches for OpenSSL by default.
293 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
294 SL_CTX_use_certificate_file. See
295 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
296 for more info. Thanks to Ko van der Sloot.
298 --- 2.1.20 2006/06/02
300 Bug #600: SRU GET, POST support for yaz-client. Introduced
301 command 'sru' which selects method SOAP/GET/POST.
303 Allow missingValueAction to be specified for the sortspec string -
304 function yaz_sort_spec. By default, the missing value action is null.
305 Use ! to specify "abort". Use = followed by stringvalue to specify default
308 Ensured that Present-handler (if defined) is called in GFS before any call to
309 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
310 searchRetrieve requests.
312 Documentation for YAZ is now based on the Docbook XML/XSLT using
313 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
314 is no longer depending on jade/openjade or docbook-to-man scripts.
315 PDF is no longer part of the distribution - but can optionally be
316 made using DSSSL/jadetex or FOP.
318 Added retrieval handling support in Generic Frontend Server to support
319 conversion between MARC/XML as well as XSLTtransforms. See
320 etc/yazgfs.xml for an example.
322 Added Authentication support to Generic Frontend Server in SRU
323 mode. Authentication using HTTP Basic is supported, as is the use
324 of 'x-username' and 'x-password' parameters in the request itself.
326 Added support for a new character set MARC8s identical to MARC8 except
327 that it converts combined characters to single Unicode characters in the
328 Latin-1 range (when possible).
330 --- 2.1.18 2006/04/24
332 ASN.1 compiler 0.4: generates brief Doxygen file header for
333 generated .h/.c files.
335 Utility yaz_iconv now supports conversion to MARC-8.
337 New facilities for the MARC module. The reading - and writing of
338 content are separate methods for the yaz_marc_t handle. The following
339 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
340 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
341 format). Write functions have prefix yaz_marc_write_.. The existing
342 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
343 available. Removed support for OAI-MARC and simplexml (not the
344 simplexml from PHP5).
346 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
347 to be returned for this connection.
349 --- 2.1.16 2006/03/31
351 Allow multiple languages and charsets to be specified with
352 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
353 negcharset iso-8859-1,utf-8
355 Translation of proximity nodes from CQL into PQF now works.
357 Moved to automake 1.8, 1.9.
359 Added function yaz_log_set_handler which allows a log handler to be
360 installed. This handler will be called for all log messages. Output
361 to file is also produced; but that can be disabled by passing NULL
362 fname to yaz_log_init_file.
364 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
366 For SRW (including GFS), accept application/soap+xml as content-type
369 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
370 produces NO stylesheet reference even if a default stylesheet is specified
373 --- 2.1.14 2006/03/14
375 Updated Windows package to include yazd.dll + yazd.lib for the
376 Development component.
378 If the environment variable YAZ_LOG is set, then it is used as a
379 string indicating the default level of logging to use if not
380 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
381 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
382 used as before. So, for example, to omit warnings from YAZ logging,
385 cql_transform() now map structure and other attributes before indexes,
386 so that index-specific structures and other attributes can override
387 defaults. So now a combination of mapping specifications such as:
389 index.dc.date = 1=date-modified 4=5
390 does the right thing.
392 cql_transform() now also respects the "always" mapping specification,
393 which establishes an initial set of attributes to be used for all
394 terms except where overridden by more specific attributes associated
395 with the index, relation or modifier.
397 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
398 which mode to use; one of "post", "get" or "soap" (SRW, default).
400 Fixes for yaz_iconv routines: changed trie-based character set conversions
401 to use only non-negative values for bit fields due to Sun's C compiler not
402 supporting negative values.
404 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
405 sequences where not read correctly. Fix by Rustam Usmanov.
407 Updated win/makefile to use options, settings which makes things
408 compile with VS C 2005.
410 --- 2.1.12 2006/02/01
412 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
414 In ZOOM socket code, use select instead of poll on MacOSX.
416 ZOOM-C now support client-side compilation of CQL into RPN that is
417 sent to the server, enabling CQL to be used against all Z39.50
418 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
419 ZOOM_query object, and submit it using ZOOM_connection_search().
420 The CQL-to-RPN translation uses a configuration file, the name of
421 which must be specified in the Connection's "cqlfile" option.
423 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
424 function, which takes as its start-term parameter a ZOOM_query object
425 (which may have had either CQL or RPN set into it).
428 --- 2.1.10 2005/11/29
430 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
431 GFS to support this as well. Backend handler, bend_srw_update, does the
432 update work. Code contributed by Ko van der Sloot.
434 Allow retrieval of Search Result-1 information in ZOOM by the use of
435 options that are attached to a result set. ZOOM documentation updated
438 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
439 UTF-8 conversion. Patch by Raj Patel.
441 Added option -m to GFS to control formatting of timestamps in log file.
443 Added 'exit' as synonym for 'quit' in yaz-client
445 Added support for specifying SRW resultSetId + resultSetIdleTime in a
446 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
447 for the new members. Patch by Ko van der Sloot.
449 Added support for SRU POST. It is supported for content-type
450 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
452 Do not build the separate Multi-threaded (MT) library libyazthread.la.
453 Instead make the library libyaz.la multi-threaded. Threading as a whole
454 can still be disabled by configure option --disable-threads. Previosly,
455 with older GLIBCs there were problems with MT libs under Apache. This
456 has now been fixed a long time ago.
458 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
461 CQL module modified to be case insensitive for relations/indexes/operations.
463 Fixed bug in CQL transform code: incorrect value relationModifieder
466 Added 'show all' command for yaz-client which retrieves all results
469 Added new yaz-client, xmles, which takes a (private) OID and
470 a document to be sent as an extended service request.
472 Describe new yaz-client commands wait_response and set_auto_wait.
474 Increase TCP/IP listener backlog from 3 (which I am guessing was
475 copied from the SunOS manual entry way back when) so SOMAXCONN, so
476 that the socket will queue as many incoming connections as it's able
477 to handle ongoing connections. In other words, it will never now
478 refuse a connection that it would be able to handle merely because
479 it's not got around to accepting() enough of the pending connections
480 yet. This is the behaviour anyway under Linux, where the listen()
481 argument is ignored; but not under BSD and on systems such as
482 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
483 YAZ-based servers should now be uniform across operating systems in
486 yaz-marcdump uses 64-bit file access on some systems. This is enabled
487 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
488 This allows yaz-marcdump to read large MARC batches (>2 GB).
490 Modified all YAZ source files - except the source which is auto-generated
491 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
494 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
495 corresponding to the existing *_setl() function. These allow option
496 values containing arbitrary valuues.
498 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
499 ZOOM_resultset_sort() in new applications. Its behaviour is identical
500 except that it returns an indicator of whether or not the sort
501 criterion was accepted (0 for OK, -1 for invalid).
505 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
506 MARC output rather than returning "new" buffer.
508 yaz-client warns about unknown init options.
510 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
514 Added support for SRW sort in Generic Frontend Server. Patch
515 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
516 sortKeys - or NULL if none is provided.
518 Fixed bug #307: It was impossible to specify indefinite/no timeout
519 for ZOOM_event. Special timeout value -1 now means indefinite timeout
522 Added support for multiple languages and charsets to be specified in
523 ZOOM. Each charset/language is separated by a blank. If negotiation is
524 in effect in init-response, Option
525 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
526 Code based on patch by Vasiliy Osadchuk.
528 Fixed bug #306: infinite recursion that occurred when calling
529 yaz_log_level_init as the first call (before other log level or
532 Fixed bug in scan handling in front end server: if preferred-Position-In-
533 Response was non-present, a NULL pointer referece was performed.
537 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
538 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
539 now defined for all those error codes. So instead of putting 109 in
540 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
541 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
543 Modified the yaz-marcdump utility to skip garbage bytes between MARC
546 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
548 Program yaz-client now exits and produces an error message if multiple
549 Z39.50 servers are specified on the command line (none or one allowed
552 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
557 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
559 Fixed bug #272: Preserve spacing for CCL terms.
563 Added support for virtual hosts and multiple backend servers for
564 the YAZ frontend server. The configution is XML based and
565 support specificition of CQL to RPN mappings and explain information.
566 See section "Virtual Hosts" in the YAZ manual.
568 Extended OPAC display utility. OPAC display utility renders
569 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
570 to supplement yaz_marc_decode_wrbuf.
572 Fixed a bug in MARC decoder that could caused it to crash for some
573 invalid MARC records. More diagnostics and warnings where added in
574 XML output (warnings, etc are stored in comments).
576 --- 2.0.34 2005/02/08
578 Fixes for UNIX domain sockets. Bug #261.
580 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
582 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
583 Added yaz_marc_subfield_str which defines subfield lead string which is
584 used in YAZ_MARC_LINE format. Default string is blank+$. Added
585 yaz_marc_endline_str which defines end of fields string used in
586 YAZ_MARC_LINE format. Default string is newline.
588 Experimental support for MarcXChange. This format can be produced
589 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
590 http://www.bs.dk/standards/MarcXchange.xsd
592 Added yaz-client commands scansize that sets maximum number of
593 entries to be returned by scan.
595 --- 2.0.32 2005/01/11
597 Added support for SRW scan in yaz-client and Generic Frontend Server.
599 * Added whereInList member to SRW Scan Term.
601 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
603 Fixed NMEM system to return aligned blocks on the smallest boundaries
604 that are suitably aligned for all possible types on the particular
605 architecture YAZ is being built for.
607 --- 2.0.30 2005/01/04
609 Fixed numerious warnings that was issued with newer versions of GCC.
611 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
612 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
615 Make YAZ Generic Frontend Server slightly faster.
617 Enhance (and reduce) logging for Generic Frontend Server.
619 Revert YAZ log system so that it flushes every write operation
620 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
622 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
623 instead of LOG_, due to name clash with syslog(3). LOG_ are still
624 present. New applications should define YAZ_USE_NEW_LOG=1 - this
625 will effectively disable old definitions.
627 --- 2.0.28 2004/11/09
629 Added yaz_log_time_format which specifies log format using
632 Added yaz_log_module_level which returns mask for a module. Value
633 is non-zero mask a if module is enabled; zero if disabled.
635 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
636 in include/yaz/cql.h.
638 Fixed bug #176: Dont throw diagnostics on empty SRU args.
640 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
642 Fixed bug #172: RPM builds does not enable SSL.
644 Doxyfile.in part of dist. Doxyfile generated by configure.
646 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
647 are given and the corresponding component does not exist.
649 Extend CCL documentation in YAZ reference. Describe r=r.
651 --- 2.0.26 2004/10/01
653 Fixed MARC->MARCXML conversion to properly deal with
654 fields, subfields, indicators having non-ASCII characters.
656 Fixed MARC->MARCXML conversion so that ASCII control characters
657 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
660 Added YAZ GFS support for conversion from Z39.50 surrogate
661 diagnostics to SRW surrogate diagnostics.
663 Bug fix: YAZ GFS did not return schema in explainResponse.
665 --- 2.0.25 2004/09/30
667 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
668 now converts recordSchema to elementSetName as well as schema URI.
670 Fixed bug in COMSTACK that prevented HTTP request packages from being
673 --- 2.0.24 2004/09/29
675 Added CCL facility r=r "range" which is similar to r=o "ordered" but
676 does not require white-space before and after the dash in a range, e.g.
677 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
680 Fixed a few AC_TRY_LINK configure tests that did not operate properly
681 due to new GCC removing "redundant" code.
683 Added yaz-client commands scanpos and scanstep that sets preferred
684 position and step-size for scan.
686 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
688 Added CCL utility ccl_qual_buf which parses one or more CCL
689 spec lines in a buffer.
691 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
692 of name and value - ignoring empty lines and comments.
694 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
696 Added odr_get_element_path which returns current element path for an
697 ODR handle. This utility is useful in error handling or user-defined
700 Added ODR_PRINT utility odr_set_stream which is is a more generic
701 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
702 to a write function and pointer to close function. The close function - if
703 non-NULL - will be called during odr_destroy.
705 Fixed bug in CCL parser where truncation char was not removed from
706 right side when truncation=both was in effect.
708 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
711 --- 2.0.23 2004/08/11
713 Fix buffer overrun in CQL parser when dealing with proximity (%).
715 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
716 to UTF-8/UCS conversion is now only based on codetables.xml.
718 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
720 --- 2.0.22 2004/08/06
722 Add support for more "commit changes" in ZOOM (uses Extended Services).
724 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
727 Yet another small fix for configure of SSL.
729 --- 2.0.21 2004/05/14
731 Fix SSL libs for configure when --with-openssl=DIR is given.
733 --- 2.0.20 2004/05/10
735 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
737 SSL comstack now uses yaz.pem certificate file on server side
738 by default. Certificate filename can be configured by calling
739 comstack function cs_set_ssl_certificate_file before cs_bind is used.
741 Fix bug regarding multiple calls to ZOOM_connection_connect.
743 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
745 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
746 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
748 ZOOM now allows inspection of X509 peer certificate for verification.
749 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
751 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
752 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
753 as "modular" but it simplifies things.
755 Added cs_get_peer_certificate to that returns peer X509 PEM.
757 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
758 NULL if SSL is unavailable.
760 Documentation about MARC decoding tools.
762 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
764 --- 2.0.19 2004/03/30
766 Rename CHANGELOG to NEWS to follow GNU style packing.
768 Fix bug with missing initialization of member in init_diagnostics.
769 This bug affects threaded version of GFS server.
771 --- 2.0.18 2004/03/20
773 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
776 Ensure zlib.dll is packed with Windows install.
778 --- 2.0.17 2004/03/17
780 Fix encoding of xsd:string to use text instead of CDATA.
782 Fix endless loop in CQL parser with unbalanced ".
784 Use a more compact way to store MARC-8 conversion tables.
786 --- 2.0.16 2004/03/16 Debian only
788 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
791 Update CQL parser to use new CQL 1.1 modifiers for booleans and
796 --- 2.0.15 2004/03/01
798 Another fix for decoding of XML packed records.
800 --- 2.0.14 2004/02/25
802 Fixes for Chunked encoding. White space not ignored after length spec.
804 Update NS and use default NS for SRW diagnostic elements.
806 --- 2.0.13 2004/02/23
808 Implement ZOOM_resultset_cache_reset which resets record cache.
810 Implement ZOOM_resultset_sort which sorts a result set.
812 Implement chunked HTTP transfer.
814 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
816 --- 2.0.12 2004/02/16
818 Added member 'schema' to bend_explain_rr structure so that backend
819 can specify explain record identifier. Defaults to Zeerex 2.0.
821 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
823 --- 2.0.11 2004/02/16
825 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
828 Added init command for yaz-client which sends "extra" init request.
830 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
831 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
833 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
835 Make ZOOM error code for "invalid query".
837 Fixed compilation for SSL which wasn't properly enabled for all platforms.
839 --- 2.0.10 2004/02/05
841 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
844 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
846 Added option -p <file> to make Generic Frontend Server to write PID file.
848 Added option -D to put Generic Frontend Server in background on its own.
850 Make ZOOM C recognize option "password". If unset, "pass" is used
851 (for backwards compatibility).
853 Fixed a bug in Generic Frontend Server that could make it crash if a
854 client sets characterSetNegotation bit, but didn't pass negotiation stuff
857 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
858 Must be issued before open, in order to be in effect.
860 --- 2.0.9-6 2004/01/12 Debian/Windows
862 Make the SRU server more picky WRT unknown params, etc.
864 Bug fix: ZOOM scan response didn't return displayTerm - when present.
866 New YAZ client command, options, that sets Z39.50 options.
868 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
869 options from a string of tokens (one token for each option bit).
871 Update SRW diagnostic code messages.
873 --- 2.0.9-5 2004/01/07 Debian/Windows
875 Handle user defined stylesheet for SRW/SRU.
877 --- 2.0.9-4 2004/01/06 Debian/Windows
879 Fix bug in decoding of Content-Length.
881 --- 2.0.9-3 2004/01/06 Debian/Windows
883 Fix a bug with decoding of XML packed records.
885 --- 2.0.9-2 2004/01/05 Debian only
887 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
889 Fix bug in SRW/SRU diagnostics decoding.
893 Fixed bug in Generic Frontend Server which could drop records exceeding
894 preferred message size. Reported and fixed by Irina Dijour.
896 Fixed calculation of package size for structured records in Generic
897 Frontend Server. Reported and fixed by Irina Dijour.
899 Fixed namespace for SRW/SRU diagnostics.
901 Fixed SEGV in yaz-client that occured for HTTP connection errors.
905 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
906 this version is incompatible with version 1.0 and older YAZ SRW/SRU
909 CQL changes to reflect recent changes to the specification:
910 * Documentation talks about context sets instead of index sets.
911 * Documentation talks about indexes instead of qualifiers.
912 * The CQL-to-PQF transformer's configuration file now uses
913 "index.set.name = <attributes>" instead of the old form
914 "qualifier.set.name = <attributes>". (Both forms are still
915 understood but the latter is deprecated.)
916 * CQL terms with no explicit index specified are now interpreted as
917 cql.serverChoice instead of srw.serverChoice (which of course
918 behaves exactly the same.)
922 MARC conversion can now generate ISO2709 output in another
923 character set. yaz-marcdump uses this facility if you invoke it
926 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
927 functions from there can be used from C++.
931 Frontend server now transfers memory from decoded packages to stream
934 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
935 references to show up.
937 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
938 the ZOOM Abstract API. The older names for the same options are still
939 also supported for the benefit of old applications.
941 ZOOM-C supports "implementationId" and "implementationVersion" options
942 to go along with "implementationName". These allow the user code to
943 specify identification strings to be sent to servers.
944 Add OID for the new ExtLite attribute set.
946 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
947 as requested/supplid by Ere Maijala <ere@atp.fi>
949 For generic frontend server, reverse the order of
950 "toolkit-supplied / application-supplied" strings sent as implementationId,
951 Name and Version. Also, remove the spaces around the slash. This brings
952 the GFS in line with the behaviour of ZOOM-C on the client side.
954 Add function ZOOM_scanset_display_term.
956 yaz-client shows scan displayTerm if present.
958 Utility yaz-iconv is now installed by default along with the man page
961 Extend configure check for OpenSSL to use pkg-config where available (such
964 Incorporate patch by Morten Bogeskov which allows a Unix file socket
965 server to specify uid/gid/mask for socket using the format
966 unix:[user=uid,][group=gid,][umask=mask,]file=path
967 If file= is omitted the existing format is assumed, e.g.
969 in which case the mask is 0666 (rw for everybody).
971 Major restructure of YAZ source. All source in libyaz is in src directory.
972 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
973 util (utility programs such as ASN.1 compiler, yaz-marcdump).
975 Added man page for utility yaz-marcdump (used to be called marcdump).
976 yaz-marcdump is installed by 'make install'.
978 Fixed a memory leak in Generic Frontend Server that occurred when decoding
979 of incoming package failed.
981 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
983 Change prototype of odr_perror: add const to message string.
985 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
987 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
988 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
989 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
990 DNS lookup. There should not be any compatibility problems with this
991 assuming that blocking=1 or 0 is used.
993 Fix bad reference in UNIX comstack in function cs_addrstr.
995 Fix for compilation on AIX.
997 The generic front-end server (server/seshigh.c) now supports returning
998 Init diagnostics to the client in User-information-field, in
999 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1002 --- 2.0.4 2003/09/04
1004 Allow any CQL relation (not just all,any,exact,scr).
1006 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1007 that features the same UI.
1009 Implemented command update0 in YAZ client which is equivalent to
1010 update but uses old of Ext Update ASN.1.
1012 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1013 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1014 Previously no OID was used for this info.
1016 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1017 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1018 returns 'malformed search term' otherwise.
1020 SortResponse member resultCount now set to NULL in sort handler of
1023 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1026 Add three new utility functions for translating OIDs between various
1027 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1028 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1029 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1030 char *oid_to_dotstring(const int *oid, char *oidbuf);
1031 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1033 Reverted modifications for ES Update definition for z_IU0Update
1034 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1035 is back to YAZ 2.0.2.
1037 String value attributes for CCL parser.
1039 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1040 which their FirstSearch server returns in Init responses, sometimes
1041 carrying useful diagnostic information when Init fails. This has the
1042 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1043 "z39.50/oclcui.asn", where its definition is somewhat different from
1044 what OCLC document on their web-site, as required to interoperate with
1047 Support for anonymous authentication in yaz-client. Use the command
1050 * Fix the OID of the Index Data-local "admin" Extended Service from
1051 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1052 the 1000, which indicates a locally-defined OID, was a mistake.
1054 --- 2.0.3 2003/06/20
1056 Fix CCL directive @case handling so that it affects string match for
1057 both CCL keywords and qualifiers.
1059 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1060 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1061 Decoder has been updated with ASN.1 changes as listed in
1062 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1063 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1064 z_IUUpdate, remains unchanged.
1066 ZOOM_record_get may now return a record in a specific character set.
1067 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1068 "from" is the character set of record as returned by target. "to" is
1069 the character set to be returned. If omitted, "to" is UTF-8.
1071 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1073 New ODR utility, odr_getelement, which returns name of element for
1074 which encoding/decoding failed.
1076 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1077 in cases where a required element was omitted.
1079 Bug fix: some MARC8 sequences were not converted.
1081 New ZOOM option "step" which specifies number of records to be
1082 retrieved in one chunk. Used in conjunction with "start" and "count".
1084 SRW support for yaz-client. Use scheme http: to use it, e.g.
1087 yaz-client no longer does (un)intelligent character set conversions
1088 by default. Can be enabled with charset and marc_charset commands.
1090 xmalloc trace fix for 64-bit systems such as DEC alpha.
1092 Solaris 2.6 compile fix.
1094 New function, cql_strerror() translates SRW error codes, as returned
1095 by cql_transform_error(), into human-readable English strings. Used
1096 in yaz-client diagnostics when appropriate.
1098 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1099 converts it into a type-1 query which is sent to the server. This
1100 makes CQL available for use with all Z-servers, as opposed to the tiny
1101 minority that can handle CQL queries themselves.
1103 --- 2.0.2 2003/04/28
1105 New Debian package layout similar to the Redhat Package layout.
1107 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1108 and search result respectively.
1110 --- 2.0.1 2003/04/25
1112 Redhat package is now several packages: libyaz (runtime libraries),
1113 libyaz-devel (development and documentation, and yaz (utility programs).
1114 Package spec file by Morten Bøgeskov.
1116 New member 'schema' in struct bend_fetch_rr which the name of requested
1117 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1118 handler MAY set this to reflect the schema of the returned record.
1120 New member 'display_term' in struct scan_entry. GFS now sets member entries
1121 and allocates scan entries to be filled by user scan handler. In previous
1122 version, entries member was allocated by the scan handler. That still works,
1123 but the GFS will ignore member display_term - assuming it was NOT set by
1124 the handler. The fact that the GFS now allocates the entries both allows
1125 for new members and makes a scan handler easier to write.
1127 Fix CQL lex buffer overflow.
1129 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1130 SRU default recordPacking is string.
1132 SRU protocol support for frontend server.
1134 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1136 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1138 Added scan for the ZOOM shell (zoomsh).
1142 * String Identifers for Schemas (Amendment 5).
1143 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1144 Old definition for schema
1145 Odr_oid *schema; /* OPT */
1150 Z_InternationalString *uri;
1151 #define Z_Schema_oid 1
1152 #define Z_Schema_uri 2
1155 * resultCount parameter to Sort Response (Amendment 1).
1156 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1158 Support for SRW 1.0 over HTTP. This is an optional feature and
1159 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1162 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1163 on the same port. SRW SearchRetrieveRequests are mapped
1164 to bend_init,bend_search,bend_fetch,bend_close.
1166 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1168 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1169 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1171 ZOOM connections are SRW based if schem http is used for hostname
1172 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1173 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1175 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1176 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1177 distance=n, order=true/false, relation=le, prox unit=word. If
1178 n is omitted, distance 1 is used.
1180 Fixed problem with C compiler include path in wrong order.
1182 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1183 on Solaris. Patch from Ko van der Sloot.
1185 New MARC decode API. All new functions operate on a yaz_marc_t
1186 handle. The most important new functions are: yaz_marc_create,
1187 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1188 decode and destroy respectively. Decoder can produce formats
1189 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1190 include/yaz/marcdisp.h.
1192 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1193 to UTF-8, UCS-32, wchar_t or Latin-1.
1195 * Prototypes for yaz_iconv_-functions moved to separate header
1196 include/yaz/yaz-iconv.h.
1198 Make a few private functions 'static' in unix.c. This prevents
1199 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1201 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1202 are set when Init Response is received.
1204 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1205 but returns diagnostic set as well.
1207 New function yaz_strerror which is a portable wrapper for
1208 strerror/strerror_r/GetLastMessage.
1210 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1211 is returned for MARC. If type is "oai", then OAI MARC is returned.
1213 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1216 --- 1.9.2 2002/11/26
1218 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1220 Fix bad race conditions on SIGTERM and terminate gracefully in
1223 Move retrieval (data1) module to Zebra since nobody seems to be
1226 Add GRS-1 render for ZOOM using same format as yaz-client.
1228 --- 1.9.1 2002/10/05
1230 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1232 Fix broken ESpec handling in data1 module.
1234 SGML reader parses comments and makes them part of the data1 tree.
1236 Added several type casts so that YAZ compiles as C++ code.
1238 ZOOM didn't handle PDU encoding failures properly.
1240 Added more Bib-1 diagnostics (approved extensions).
1242 GNU configure: better check for iconv.
1244 More portable use of accept, getpeername. Check for socklen_t. Use
1245 int/size_t if socklen_t is not defined.
1249 PQF parser rejects bad queries - including those with extra
1250 characters in them. PQF parser used to silently ignore that.
1251 Cleaner API for PQF added, which allows you to get detailed
1252 error information for bad queries (see yaz/pquery.h).
1254 Fixed bug in ZOOM_record_get for type "database".
1256 Implemented mini iconv library supporting conversions between
1257 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1259 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1261 --- 1.8.9 2002/08/20
1263 Fixed ZOOM C record cache so that preferredRecordSyntax and
1264 elementSetName is used to check for already fetched records.
1266 --- 1.8.8 2002/08/02
1268 Added three members in bend_initrequest structure to facilitate
1269 character set negotiation.
1271 Fixed a bug in frontend server that could cause indefinite
1272 loops under rare conditions.
1274 Revised character set utilities (charneg.h) so that encoding
1275 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1277 For PQF, directive @term <type> sets term type for Scan/Search.
1278 Here <type> is general, string, numeric, null. The term type
1279 is inherited - just like @attr.
1281 New call odr_set_charset that sets character set conversion for
1282 international-strings on a ODR stream. Prototype is:
1283 int odr_set_charset(ODR o, const char *to, const char *from);
1284 The InternationalString is still represented as C string in YAZ
1285 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1286 won't). On the protocol level, you can use any encoding.
1288 Support for UNIX sockets in ZOOM.
1290 Solaris recv sometimes returns errno == ENOENT. It is treated as
1291 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1293 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1294 both client and server. Code by Morten Bøgeskov.
1296 --- 1.8.7 2002/05/22
1298 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1299 that they can be used directly from Visual Basic. You must recompile
1300 your windows APP if you're using ZOOM.
1302 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1303 Commands "lang" and "charset" sets language and character set respectively.
1304 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1305 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1307 Attributes from multiple CCL fields may be OR'ed rather than merged
1308 using directive "@field or". Fields are still merged by default -
1309 equivalent to "@field merge".
1311 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1314 Fixed bug in zget for parameter ExtendedServicesResponse.
1318 --- 1.8.6 2002/03/25
1320 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1322 Client displays USR.1:SearchResult-1 (hits per term).
1324 Additional Search Info for search in Generic Frontend Server.
1326 Fixed CCL parsing of "field=s".
1328 WIN32 installer - using the excellent NSIS software from nullsoft.
1330 Fixed CCL parsing of "field = - <number>".
1332 Added function yaz_marc_decode that decodes MARC for line mode
1333 display or XML (similar to that used by JZKit).
1335 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1336 Z39.50. But ISO/ILL was, however.
1338 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1339 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1341 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1342 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1344 --- 1.8.5 2002/02/03
1346 New YAZ client features: Command completion and new commands:
1347 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1348 Code provided by Jacob Poulsen.
1350 New call oid_trav, that visits all registered OIDs via callback.
1352 Function ZOOM_record_get now returns const char pointer rather than
1353 void pointer. It saves a lot of type casts.
1355 For YAZ client, command "auth" now allows you to set authentication
1356 in IdPass style. It is enabled when three tokens are given - order
1357 is user, group and password.
1359 Fix memory leaks in MARC record handling for ZOOM.
1361 New option for YAZ client, -k <kilobytes> that sets
1362 maximum record size. Similar to -k option for generic frontend
1363 server and yaz-ztest.
1365 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1367 Prefix query parser reports "fail" when bad attribute set is given.
1369 Fix in MARC decoder. Proximity logging. Fix for attribute set
1370 in scan handler for server. Patches by Shigeru Ishida.
1372 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1375 Configure option --with-openssl=<dir> now works when a directory is
1376 specified. Patch provided by Morten Bøgeskov.
1378 New option for YAZ client, -u <auth>, that sets authentication.
1380 ZOOM fix: error information was sometimes "missing", since error
1381 was cleared/reset too when it shouldn't.
1383 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1385 --- 1.8.4 2002/01/04
1387 Scan for ZOOM API. New object ZOOM_scanset. New functions
1388 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1389 ZOOM_scanset_destroy.
1391 New ZOOM function, ZOOM_connection_last_event, that returns type
1392 of last event (such as "receive data", "send data", "apdu received",
1395 New ZOOM option, schema, that specifies schema for retrieval.
1397 New CCL feature. Qualifiers can be aliases for one or more
1398 other qualifiers (if more than one is given, OR is used).
1400 ZOOM uses named result sets if target supports it.
1402 Two new YAZ client commands: . (dot, which sources a script of YAZ
1403 client commands), and ! (to execute shell command.). Implemented
1406 Working on Debian packages.
1408 --- 1.8.3 2001/11/19
1410 YAZ client enables named result sets only if target supports it.
1412 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1414 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1415 with key="host" to get same result.
1417 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1418 Function Z3950_resultset_record(s) returns references to records
1419 "owned" by resultset. To become owner use Z3950_record_clone.
1421 Function z_ext_record handles Extended Services. Thanks to
1424 --- 1.8.2 2001/11/12
1426 CCL Parser fix: ignore token comma when dealing with and-lists.
1428 Documentation updates for COMSTACK.
1430 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1431 Changed prototype Z3950_records. For some functions, int parameters
1432 were changed to size_t.
1434 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1437 New MARC decode/display function, marc_display_exl, which properly rejects
1438 non-ISO2709 records. YAZ client uses it.
1440 --- 1.8.1 2001/10/29
1442 Fix bug: local attribute set wasn't set correctly in PQF strings.
1446 * Old Z39.50 codecs no longer supported.
1448 Added ZOOM C binding. See http://zoom.z3950.org/
1450 Renamed states for COMSTACKs to avoid confusion with events.
1452 Implemented cs_look and proper cs_rcvconnect.
1454 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1456 Configure detects POSIX threads on OpenBSD.
1458 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1459 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1461 When error is returned from present handler, non-surrogate diagnostic
1462 is returned in present response (and fetch handler is no longer called).
1464 * Minor adjustments to pquery parser (PQF). Token characters may be
1465 escaped by using backslash (C-style).
1467 PQF parser allows string attribute values to be specified. For @attr,
1468 non-numeric characters after the equal-sign are treated as strings
1469 (e.g. @attr 9=title).
1471 CCL trunction character may be defined (@truncation in file)
1473 * function zget_ExtendedServicesRequest sets waitAction to
1474 waitIfPossible (was wait).
1476 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1479 CCL operator names may be set in field definition files (CCL_bibset).
1480 See ccl/bib1 for an example.
1482 Fixes in ASN.1 compiler for C++ compatibility.
1484 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1485 and "op_or" to avoid conflict with C++.
1487 Fixed problem with GNU readline detection on Redhat 7.0.
1489 Added step-size for Scan backend handler.
1491 Fixed bug that made the frontend server crash when no attribute
1492 set was specified for scan.
1494 Front-end server automatically switches to original working directory
1495 when installed as an NT service. Previously -w had to be specified to
1498 Added extended attributes for retrieval module (data1), so that data1
1499 records carry d1_readXML/SGML attributes. d1_read also supports
1500 null-data rules ( <tag/>)
1502 On UNIX when POSIX threads are available, a separate library libyazthread
1503 is created. Programmers should link with that library and the yaz library
1504 when using threads. The reason for the split was that some applications
1505 on Linux, such as Apache, doesn't work well when using shared objects that
1508 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1509 (or any frontend server) in SSL mode by specifying ssl: followed by
1510 address. Only tested on UNIX.
1512 Added feature for CCL module. Virtual structure s=al or s=ol generates
1513 and-list and or-list respectively instead of phrase search.
1517 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1518 log_mask_str. This was done to avoid name conflicts with other libraries
1519 (such as other PHP extensions).
1521 Added raw OID member for preferred record syntax (request_format_raw)
1522 and returned record syntax (output_format_raw) for backend fetch method.
1524 Config file yaz-config now accepts options so that it returns specific
1525 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1527 Shared library support for UNIX using GNU libtool.
1529 * Modified backend interface. Request/Response struct's replaced by
1530 one read/write C struct. For example bend_fetchrequest and
1531 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1532 Every handler - even search has to be registered in bend_init
1533 handler. This means that the YAZ library no longer refers to
1534 external functions and it makes it possible to make the whole
1535 thing a single DLL/SO.
1537 Added Segment handler for backend server.
1539 Added Zmbol/Zebra administrative functions to YAZ client.
1541 Threaded frontend server on UNIX (when POSIX Threads are available).
1542 Starting the server with option -T enables multi-threading.
1546 Added configure option --enable-comp/disable-comp to control use
1547 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1548 located in sub directory asn.
1550 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1551 in ${exec_prefix}/bin along with the other programs yaz-client and
1554 GNU automake used to maintain makefiles.
1556 Added several OID's.
1558 Changed retrieval module so that we can load records with no abstract
1559 syntax defined. Tagpaths in these records are fully composed of string
1562 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1566 On UNIX, the generated makefile now supports a proper 'make install'.
1567 The prefix can be set via GNU configure to set the install location
1568 (default is /usr/local).
1570 * YAZ programs client and ztest were renamed to yaz-client and
1571 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1572 locations, such as /usr/bin,/usr/local/bin,etc.
1574 * YAZ Header files were moved from include to include/yaz. YAZ Header
1575 files are referred to as include <yaz/log.h> rather than <log.h>.
1576 The YAZ include path (-I ..) is therefore the same as before. Programmers
1577 should update their #include statements or use -Ipath/include/yaz
1578 instead. The main motivation for doing this change is that YAZ header files
1579 can be installed in "standard" locations /usr/include,/usr/local/include
1580 without introducing conflicts, since ALL YAZ header files are stored
1581 in subdirectory yaz (under /usr/include for example).
1583 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1584 rather than project/workspace files. We switched because project files
1585 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1588 Changed name of logging function, logf, to yaz_log, to prevent name
1589 clash with some math-log functions. The YAZ header log.h defines logf
1590 to yaz_log (#define) so there should be no incompatibilities by this
1593 Added bend_start/bend_stop handlers for server. These handler are
1594 called on start/stop of server. For windows they are called whenever
1595 a service is started/stopped.
1597 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1598 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1599 in util/yc.tcl. The auto-generated C code structures are, in a few
1600 cases, incompatible with the old decoders. There are differences in the
1601 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1602 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1603 The preprocessor variable ASN_COMPILED is defined when the compiled
1604 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1605 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1606 wish to use the old encoders/decoders you can specify --disable-yc
1609 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1610 version so that it supports both new - and old version of DB Update
1612 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1613 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1614 change. The name parameter can be set to 0 in which no name is specified
1615 for the construction. The macros odr_implicit and odr_explicit sets name
1616 parameter to zero for the construction involved. New macros
1617 odr_implicit_tag and odr_explicit_tag are similar to the others,
1618 except that a name parameter is added. For programmers' that don't use
1619 ODR they probably only need to change the call to z_APDU and z_External.
1621 Added access control facility by interfacing the TCP wrapper library.
1622 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1623 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1624 name of the daemon and enables the access control as specified in
1625 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1627 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1628 den Dool <H.M.vdnDool@kub.nl>.
1630 Added reference ID parameter to most functions in server API - refer
1631 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1633 Changed name of ccl library to libccl.a (was ccl.a).
1635 Fixed bug in decoder for Explain (Category TargetInfo).
1637 Added support for GNU readline in client. Thanks to Jacob Poulsen
1638 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1640 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1641 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1642 IMPLEMENTATION! This change was made to the development version before
1643 the ZIG decided to retract the amendment. If any users MUST be
1644 compatible with the original Update definition, PLEASE CONTACT US, and
1645 we will include a separate definition corresponding to the old Update
1646 ES. Note that because of the change to the ASN.1 of the
1647 TaskPackageRecordStructure we cannot define a single structure that
1648 will support both versions.
1650 * Added const modifier to buffer parameter for some ODR/BER encoding
1651 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1652 completeWAIS, odr_dumpBER.
1654 Fixed bug in client.c which caused a crash when a scanResponse didn't
1655 contain positionOfTerm.
1657 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1658 * will cause an error in a client if a non-YAZ target sends both a
1659 * list of Scan entries and non-surrogate diagnostics.
1661 Retrieval module enhancements. Tag sets may be typed in the reference
1662 to it. From the .abs-file the "tagset" directive takes a third optional
1663 integer type for the tag set referenced. From a .tag-file the "include"
1664 directive takes a third optional type as well. The old "type" directive
1665 in the tag set itself is still recognized but acts as the default type
1668 Backend interface change. Individual Scan terms returned from bend_scan
1669 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1670 in include/backend.h.
1672 Retrieval module enhancements. Multiple tag sets and attribute sets may
1673 be specified in abstract syntax specs. Revised the error/warning for
1674 logging messages reported by the retrieval module when reading the
1677 Object Identifier system (oid_..) changed. The API is backwards
1678 compatible but the oid-routines now allocates new OID's when needed.
1679 Raw OID's may be specified in oid_getvalbyname.
1681 YAZ now uses GNU configure to generate Makefile(s).
1683 * Minor changes in some of the member names of DeleteResultSetRequest and
1684 DeleteResultSetResponse. See include/proto.h.
1686 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1687 and added member 'languages' in TargetInfo (which was missing).
1689 Changed the way attribute sets are handled in the retrieval
1690 module. These are now cached, just like the abstract syntaxes
1693 Changed YAZ so that it links with compiled ASN.1.
1695 Added Explain-schema definitions and mapping routines. The following
1696 Explain categories have been implemented: AttributeDetails,
1697 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1699 Fixed minor bug in Windows version of Server Library.
1701 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1703 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1705 Added EXTERNAL: UNIverse Resource Report (non-standard).
1707 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1708 ENUMERATED and SET OF.
1710 * Added 'const' to some of the char pointer arguments for the
1711 functions, data1_read_node, data1_getelementbytagname,
1712 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1715 Fixed bug in data1_insert_taggeddata - the last_child member of
1716 parent wasn't initialised.
1718 * Changed data1_read_record and data1_read_node so that the supplied
1719 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1720 doesn't refer to any parts of the "SGML"-buffer.
1722 Fixed bug in server library (Windows version of statserv_remove).
1724 * Changed code so that it compiles as C++. The type definition
1725 of Odr_fun which is a member of Odr_arm was changed. The result is,
1726 that an explicit typecast is needed for the fun pointer when
1727 using Odr_arm - as in:
1728 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1730 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1732 Implemented the new structured date and time definition as approved
1733 by the ZIG. Added schemaId element to the specificTag in Espec-1
1734 (also approved at the last ZIG). Thanks to RVDM.
1736 Added some Object identifiers (RVDM).
1738 Changed the Update Extended Service (RVDM).
1740 Added command "refid" to client which specifies referenceId for
1741 the following requests.
1743 Implemented extended service handling for server. See ztest.c
1744 for an example as well as backend.h. New handlers are registerd
1745 in the Init handler.
1747 * Changed interface for sort in server.
1749 Added new members to statserv_options_block. It allows a server
1750 to read options from another source than just the command line. Thanks
1751 to Charles Woodfield.
1753 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1754 renamed to zboolean. Some C++ compilers complained about the name.
1756 Minor changes to gils.abs. Added index 's' (sort) on title
1757 and date/time-last-modified.
1759 --- 1.4pl2 1998/1/30
1761 Fixed bug in server library regarding inetd mode (-i). This bug
1762 was introduced by release 1.4.
1764 --- 1.4pl1 1998/1/29
1766 Added sort facility in client and backend server interface.
1768 Fixed problem with dependencies in Makefile(s).
1770 Fixed bugs for encoders/decoders of extended services and
1773 Implemented sub-tree feature for schemas. Sub-trees are
1774 referenced in *.abs-files. See explain.abs for an example
1775 of the use of this feature.
1777 Modified bib1.att; local attributes for ANY didn't include
1778 ANY itself (only affects use of the retrieval module).
1780 Fixed bug in plain SGML reader in function data1_read_node:
1781 tags with prefix "var" was incorrectly interpreted as variants.
1783 Added feature "sub-schemas" to enable references to - and definitions
1784 of - group of elements.
1786 * Removed member parent from type data1_element (in data1.h).
1788 Implemented function odr_nullval() that returns the value of
1791 * Removed member num_children from data1_node (in data1.h).
1793 Made NT service interface part of the server library. The
1794 function statserv_main uses the NT service when required and
1795 calls the statserv_start / statserv_close routines.
1797 Routine zget_SearchRequest and zget_PresentRequest fills
1798 resultSetName/Id member with "default" instead of "Default".
1800 Fixed memory leak in server. Request queue member wasn't freed.
1802 Fixed nmem_exit so that memory is freed.
1806 Revised the CCL parser utility to be thread safe.
1808 Added function, oid_ent_to_oid, to replace the function
1809 oid_getoidbyent, which is not thread safe.
1811 * Added nmem_init and nmem_exit to initialize and release
1812 NMEM resources. Function nmem_init should be called once in the
1813 initial thread before NMEM/ODR is used. statserv.c and client.c
1814 have been changed accordingly. The change was necessary to make
1815 NMEM thread safe. The NMEM memory pool is shared amongst threads
1816 in a process. Unix-based applications will still work fine without
1819 Added NT Services interface for the the Z39.50 (statserv) Server.
1820 Refer to the ztest.c source on the usage.
1822 Windows 95/NT port using MSVC5.0. Project files are included in the
1825 * Defined new 'global' handle for the retrieval (data1) system. The
1826 new handled, data1_handle, describes the state of the data1 system.
1827 This handle is passed as first argument to virtually all
1828 data1 related routines. The functions data1_create and data1_destroy
1829 creates and destroys a data1 handle respectively.
1831 Added ODR encode stream member to all backend request structures
1832 init, search, scan etc. This stream should be used to allocate all
1833 memory used for the response when thread safe operation is needed.
1835 Changed the comstack utility, cs_addstr, to be thread safe. The
1836 returned hostname string returned by the function is now part the
1839 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1840 function. The cs_straddr takes a COMSTACK handle as argument, so this
1841 function must be used after cs_create and before bind/connect.
1842 This function is thread safe.
1844 Moved test server to 'ztest' directory - generic server code still
1845 in 'server' directory.
1847 Made prefix query (pquery.c) utility thread safe.
1849 Added new function modifier YAZ_EXPORT to 'export' public DLL
1850 functions when using windows (see include/yconfig.h).
1852 Added definitions to the OID database (util/oid.c) (RVDM).
1854 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1856 Added call to ccl_rpn_delete in client program.
1858 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1859 release of RPN structure.
1861 Added support for C++, headers uses extern "C" for public definitions.
1862 With input from RVDM.
1864 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1865 Thanks to Ronald van der Meer (RVDM).
1867 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1869 Added support for private extensions to the OID database
1870 (oid_setprivateoids()). Thanks to RVDM.
1872 Added optional, physical ANY (key replication)
1874 Fixed null-reference problem in GRS-1 output filter.
1876 Proximity operator added to Prefix Query Format (PQF).
1878 In test client command "base" accepts multiple databases.
1880 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1884 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1886 Smallish bug-fixes in the new encoders/decoders (explain).
1888 Bug fixed in DeleteRequest.
1890 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1892 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1894 Added SOIF syntax (using private OID for now) to retrieval module and client.
1896 Added Update extended service.
1898 Added SearchResult-1 additional info structure.
1900 Added optional CCL (ISO8777) interpreter as separate module. Available
1903 --- 1.2 1996/6/10 (1st anniversary release)
1905 Added Summary record syntax. Lightly tested.
1907 Added OPAC record syntax. Untested.
1909 Added ResourceReport service encoders/decoders. Untested.
1911 Fixed bug in z_Unit - wrong tagging on unitSystem.
1913 Fixed bug in the DiagRecs decoder.
1915 Added options for max PDU size and session timeout to frontend-server.
1917 Added documentation of query-language parsers and other supporting utilities.
1919 [frontend-server] Added Attribute set to the bend_scanrequest API.
1921 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1922 surrogate diagnostics were generated.
1924 [retrieval] Allow multiple local values for attribute.
1926 [retrieval] Allow multiple attributes per element in .abs files. index type.
1928 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1930 --- 1.1pl2 1996/4/10
1932 Minor changes, mostly specific to Zebra's requirements (retrieval)
1936 Repaired bug in frontend server when running multiple listening
1937 endpoints in dynamic mode.
1939 z_External() now won't break if a known, ASN.1 value comes encapsulated
1940 in an octet-string. The value will pass through unmodified in an Odr_oct.
1942 Added a bit of code to the demo client to decode & display
1943 ASN.1-structured records represented in the octet-aligned branch of
1944 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1946 Added z_ext_getentbyref() to the ASN module. Doc updated.
1948 * Completed the SCAN definition in the ASN module. This may break SCAN
1949 code based on older YAZ-versions at compile-time. The fix is easy -
1952 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1953 under the SCAN definition. Remember to initialize this, server-people.
1955 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1956 that this does not extend to ODR and ASN.
1958 Comstack allows insertion of established socket (primarily for
1959 inetd-operation of servers). Doc updated.
1961 Front-end server can now start from the inetd in TCP mode. Doc
1964 --- 1.0pl4 1996/1/24
1968 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1969 the rank and record number.
1971 Adjustments to the frontend server.
1973 Fixed diagnostic BER dumper. It ignored the file argument.
1977 Various changes to retrieval module.
1979 Changed the union discriminators of the protocol files from enums to
1980 ints paired with #defines.
1982 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1985 *Changed operator in the RPN structure to 'roperator', again to avoid a
1988 Fixed problems in Explain decoders/encoders.
1990 --- 1.0pl2 1995/12/6
1992 Memory bug in log module fixed.
1994 --- 1.0pl1 1995/12/5
1996 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1998 Bug in Explain DatabaseInfo module fixed.
2000 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2004 The shift to v1.0 signals that we now consider the *core* functionality
2005 of YAZ reasonably stable (the core being more or less equivalent to
2006 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2007 tested (Explain not at all - though that will happen soonish).
2009 Minor changes to code to support Windows port.
2011 Various minor changes after we're getting to use GRS-1 & co. more.
2013 Added Espec-1 format.
2015 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2016 of the protocol and it cannot be selected when encoding (maps into 'string'
2017 when decoding). Needed to talk to some servers.
2019 Demo client can request simple element set names.
2021 Added Diagnostic Format encoders/decoders.
2023 Added simple Close handling to frontend server (no hooks for resource
2024 reporting yet), and demonstration client.
2026 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2028 --- 1.0b3 1995/08/24
2030 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2031 handled incorrectly when records were requested in the searchResponse. This
2032 will only affect you if you use the frontend-server.
2034 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2035 Test-client will ask for and print GRS1. Ztest will return dummy records
2038 Added Explain encoders/decoders to the service-level API. Untested.
2040 Added Extended Services: Item Order encoders and decoders to the Service-
2041 level API. Untested. We could use a recent copy of the pertinent bits
2042 of the ILL protocol to add those bits.
2044 Added diagnostic format 1 encoders/decoders to the service-level API.
2047 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2048 odr_cons.c, which causes a more correct output.
2050 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2051 was always set to 0 when no records were requested in the searchRequest.
2053 * Added better external-handling. This shouldn't harm old code that
2054 *encodes* externals. It can break code that looks for a
2055 'single-ASN1-type' representation, since those types that are known
2056 are now decoded immediately. Look at the SUTRS sample code in
2057 seshigh.c and client.c. Documentation updated.
2059 Handling of structured records in bend_fetchresponse. Length -1 marks
2060 structured record, type is deduced from format field.
2062 --- 1.0b2 1995/06/27
2063 Fairly quick maintenance release to add SUTRS support.
2065 Fixed handling of SUTRS records in the demonstration client.
2067 * Added format field to the bend_fetchrequest and bend_fetchresponce
2068 structures of the backend API (frontend server). When the record is
2069 returned, the value of the format field is mapped to an OID. The
2070 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2071 of the record. The special value VAL_NONE in the bend_request means
2072 that no specific format was requested by the client. Documentation
2073 updated accordingly. Test server (ztest) will return a fixed dummy
2074 SUTRS record if your client requests SUTRS.
2076 Documentation updated accordingly.
2078 You can now set external libraries and RANLIB support in the top-level
2082 First public release.
