1 API changes to ZOOM. Functions for setting options returns int, rather
2 than void, so we have a way to flag unknown options. ZOOM_resultset_sort1
3 has become "the" ZOOM_resultset_sort. (and old ZOOM_resultset_sort is removed).
4 ZOOM_connection_scan1 removed. The generic scan is ZOOM_connection_scan
5 and the ZOOM_connection_scan_pqf is a handy short-hand taking a PQF string
8 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
9 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
11 Deprecated functions for yaz_marc-removed.
13 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
16 Branch split: YAZ_2_1_55_branch
20 Fix to ZOOM-C so that transparent reconnection is properly handled on
21 connections that are in asynchronous mode.
23 Fixed compilation on OpenBSD 4.0.
25 Large strings in GRS-1 records are now properly displayed in yaz-client.
27 Added character conversion support for "advancegreek"; based on patch from
30 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
31 sequence is met. Before the error was not set so it would be unknown.
33 Adjust yaz-marcdump MARC reader so that it skips until record separator
38 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
39 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
40 fd_set structure used as a bitmask for the FDs to be selected on.
42 Using ACX_PTHREAD macro to check for POSIX threads.
44 Fixed have-vsnprintf check.
48 Fixes for configure on BSD. Bug #900.
50 Added snprintf/vsnprintf wrappers for systems that don't have
51 limits (heavens forbid).
53 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
54 created before all previous tasks were completed and removed from the
55 task queue, the new task could be removed by a mistake.
57 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
59 Implemented pass-through CQL-to-PQF conversions. Bug #861.
61 Fixed bug #832: Problem with MARC/charset in yaz-client.
63 Fixed bug #668: save command line history for yaz-client.
65 Fixed bug #830: pkg-config support.
69 Extended ZOOM result set options with two options that may be read by
70 a client: resultSetStatus and presentStatus with values as specified for
72 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
74 Fixed bug #827: Using SSL fails on Debian etch.
76 Fixed bug #826: Weird looking chars for set of MARC records.
78 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
79 that is treated as an ItemOrder with itemRequest being an XML document
80 external. The value of "doc" is the content.
82 Extended the GFS search facility. New member of bend_search_rr
83 'estimated_hit_count' signals that hits is known to be an estmate
84 (higher or lower than real hit count). New member 'partial_resultset'
85 signals that the search was partial (hit count is lower or equal than
86 real hit count). For Z39.50, the information is stored in resultSetStatus
87 member of SearchResponse APDU. For SRU, the information is signalled
88 via SRU diagnostic 59: "Result set created with valid partial results
91 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
95 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
97 Added ZOOM_connection_peek_event.
99 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
100 the following new functions:
101 ZOOM_event_nonblock, ZOOM_connection_process,
102 ZOOM_connection_get_{socket,mask,timeout},
103 ZOOM_connection_fire_event_{timeout,socket}.
104 The existing blocking event handler, ZOOM_event, is a wrapper for the
105 + blocking ZOOM_event_sys_{poll,select}.
107 Implemented function ccl_xml_config which parses XML version of CCL
108 configuration (bug #798).
110 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
112 Added timings utility (yaz/timing.h)
114 --- 2.1.44 2007/01/03
116 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
119 Fixed bug #779: Rotation of apdu.log fails.
121 Fixed for character set conversions:
122 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
123 Honor G1 set in MARC-8 decoding.
125 --- 2.1.42 2006/12/17
127 Fixed bug #775: char conversion does not handle Alternative UTF-8
130 Implemented function yaz_marc_read_line which parses MARC line format
131 records. There is a wealth of formats out there. So far, this function
132 reads line records produced by yaz_marc_write_line.
134 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
135 more generic and easier to remember(!) options: -i format and -o format
136 which specifies input format and output format respectively - where
137 format is one of "marc", "marcxml", "line", "marcxchange".
139 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
140 does not print anything except warnings for records.
142 For yaz-marcdump, added support for MARC split into files (-s) with a given
145 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
146 spec, at http://www.loc.gov/standards/sru/record-update/
147 This has changed the binary layout of the following structs:
148 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
149 bend_update_rr . Patch by Ko van der Sloot.
151 Added GFS utility function bend_assoc_is_alive which returns 1 if
152 association is still alive (client is connected); 0 otherwise (client
153 closed connection). This allows busy servers to stop working for
156 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
157 been a separate piece of software. This version of ziffy has been modified
158 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
160 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
162 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
163 Client code may now interrogate options such as "init_opt_sort" to
164 find out whether the server claims to support various options.
166 --- 2.1.40 2006/11/27
168 Added utilities yaz_{set,get}_esn to set/get element set name from
171 Removed the build of libyazthread.la. The libyaz.so is the threaded version
172 of YAZ and has been so since YAZ 2.1.10.
174 Implemented ZOOM_record_error which returns error information for
175 record (surrogate diagnostic).
177 --- 2.1.38 2006/10/31
179 Updates for SRU Update by Ko van der Sloot:
180 1. Changed name from "operation" to "action"
181 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
182 versions in the code, marked as 'backward compatible'.
183 3. Added diagnostics for SRU Update.
185 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
187 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
189 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
191 For GFS, fixed problem with SRU diagnostic 'First record position out of
192 range' being issued for 0 hits.
194 zoomtst10 part of Windows Build.
196 --- 2.1.36 2006/10/13
198 Implemented yaz_filepath_comp which splits a path into file path
199 components (required by Zebra 2.0.3+).
201 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
202 BSD inspired license until now so this should not have any real impact on
203 anybody. See http://www.opensource.org/licenses/bsd-license.php
205 Fixed bug #687: Missing log lines.
207 Fixed bug #678: CQL to PQF translation does not preserve double-quote
210 Fixed bug #689: SRU diagnostics to be added.
212 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
213 whether a connection is idle (no more work do do).
215 --- 2.1.34 2006/10/04
217 Change type of optval from long to int for invocation of setsockopt with
218 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
220 Added support for specifying the max log file size for the Generic
221 Frontend Server. The size is given with option -r.
223 --- 2.1.32 2006/09/21
225 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
227 --- 2.1.30 2006/09/17
229 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
232 Fixed bug in Generic Frontend Server that could cause a server to stop
233 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
235 For the generic frontend server, the maximum record size is used as maximum
236 size of incoming packages (SRU + Z39.50). The value until was previously
237 only used in Z39.50 Init negotiation and, later, in a session controlled
238 sizes of records returned. This is controlled using -k option. It can be
239 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
241 --- 2.1.28 2006/09/04
243 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
246 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
248 New option for yaz-marcdump -lpos=value which allows setting a portion
249 of MARC header to a certain value.
251 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
253 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
254 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
256 --- 2.1.26 2006/08/15
258 Fixed problem with SRU mode type (soap, get, post) for yaz-client
261 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
263 --- 2.1.24 2006/08/08
265 Fixed MARC ISO2709 encoding routines to deal with character set
268 Minor changes to GFS logging. Database included in search request log
271 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
272 cached/multiple records.
274 Shared libraries are built by default on Unix+configure.
276 Changed cql2pqf transformation to use a different evaluation order. The
277 new order is: always, relation, structure, position, truncation, index
278 and relationModifier. Old order was: always, relation, relationModifier,
279 structure, index, position, truncation. Note that the the latter ones
280 override former ones for identical attributes.. The new scheme means that
281 it is possible to override any existing attribute with a relationModifier.
282 And also that it is possible to override everything for the index rule
283 (except the ones listed in relationModifier). No order is perfect but this
284 one, we believe, covers more real cases.. The "always" should have been
285 called "default", since the attributes there can be overridden with all
288 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
289 compilation phase, but also for yaz-config --cflags output. This allows
290 us to have public headers with Libxml2 stuff in them . It should also,
291 eventually, make Libxml2 checks redundant in packages using YAZ, such
294 --- 2.1.22 2006/06/15
296 Changed SRU update structure bend_update_rr so that SRU diagnostics are
297 stored in uri, message and details.. Previously diagnostics were stored
298 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
299 compatibility.. but he's probably the only one affected, so.
301 Added support for CCL, compiled on the client side, in ZOOM-C. This
302 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
303 input; the resulting query objects can be used for for searching with
304 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
306 YAZ' configure searches for OpenSSL by default.
308 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
309 SL_CTX_use_certificate_file. See
310 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
311 for more info. Thanks to Ko van der Sloot.
313 --- 2.1.20 2006/06/02
315 Bug #600: SRU GET, POST support for yaz-client. Introduced
316 command 'sru' which selects method SOAP/GET/POST.
318 Allow missingValueAction to be specified for the sortspec string -
319 function yaz_sort_spec. By default, the missing value action is null.
320 Use ! to specify "abort". Use = followed by stringvalue to specify default
323 Ensured that Present-handler (if defined) is called in GFS before any call to
324 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
325 searchRetrieve requests.
327 Documentation for YAZ is now based on the Docbook XML/XSLT using
328 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
329 is no longer depending on jade/openjade or docbook-to-man scripts.
330 PDF is no longer part of the distribution - but can optionally be
331 made using DSSSL/jadetex or FOP.
333 Added retrieval handling support in Generic Frontend Server to support
334 conversion between MARC/XML as well as XSLTtransforms. See
335 etc/yazgfs.xml for an example.
337 Added Authentication support to Generic Frontend Server in SRU
338 mode. Authentication using HTTP Basic is supported, as is the use
339 of 'x-username' and 'x-password' parameters in the request itself.
341 Added support for a new character set MARC8s identical to MARC8 except
342 that it converts combined characters to single Unicode characters in the
343 Latin-1 range (when possible).
345 --- 2.1.18 2006/04/24
347 ASN.1 compiler 0.4: generates brief Doxygen file header for
348 generated .h/.c files.
350 Utility yaz_iconv now supports conversion to MARC-8.
352 New facilities for the MARC module. The reading - and writing of
353 content are separate methods for the yaz_marc_t handle. The following
354 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
355 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
356 format). Write functions have prefix yaz_marc_write_.. The existing
357 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
358 available. Removed support for OAI-MARC and simplexml (not the
359 simplexml from PHP5).
361 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
362 to be returned for this connection.
364 --- 2.1.16 2006/03/31
366 Allow multiple languages and charsets to be specified with
367 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
368 negcharset iso-8859-1,utf-8
370 Translation of proximity nodes from CQL into PQF now works.
372 Moved to automake 1.8, 1.9.
374 Added function yaz_log_set_handler which allows a log handler to be
375 installed. This handler will be called for all log messages. Output
376 to file is also produced; but that can be disabled by passing NULL
377 fname to yaz_log_init_file.
379 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
381 For SRW (including GFS), accept application/soap+xml as content-type
384 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
385 produces NO stylesheet reference even if a default stylesheet is specified
388 --- 2.1.14 2006/03/14
390 Updated Windows package to include yazd.dll + yazd.lib for the
391 Development component.
393 If the environment variable YAZ_LOG is set, then it is used as a
394 string indicating the default level of logging to use if not
395 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
396 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
397 used as before. So, for example, to omit warnings from YAZ logging,
400 cql_transform() now map structure and other attributes before indexes,
401 so that index-specific structures and other attributes can override
402 defaults. So now a combination of mapping specifications such as:
404 index.dc.date = 1=date-modified 4=5
405 does the right thing.
407 cql_transform() now also respects the "always" mapping specification,
408 which establishes an initial set of attributes to be used for all
409 terms except where overridden by more specific attributes associated
410 with the index, relation or modifier.
412 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
413 which mode to use; one of "post", "get" or "soap" (SRW, default).
415 Fixes for yaz_iconv routines: changed trie-based character set conversions
416 to use only non-negative values for bit fields due to Sun's C compiler not
417 supporting negative values.
419 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
420 sequences where not read correctly. Fix by Rustam Usmanov.
422 Updated win/makefile to use options, settings which makes things
423 compile with VS C 2005.
425 --- 2.1.12 2006/02/01
427 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
429 In ZOOM socket code, use select instead of poll on MacOSX.
431 ZOOM-C now support client-side compilation of CQL into RPN that is
432 sent to the server, enabling CQL to be used against all Z39.50
433 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
434 ZOOM_query object, and submit it using ZOOM_connection_search().
435 The CQL-to-RPN translation uses a configuration file, the name of
436 which must be specified in the Connection's "cqlfile" option.
438 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
439 function, which takes as its start-term parameter a ZOOM_query object
440 (which may have had either CQL or RPN set into it).
443 --- 2.1.10 2005/11/29
445 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
446 GFS to support this as well. Backend handler, bend_srw_update, does the
447 update work. Code contributed by Ko van der Sloot.
449 Allow retrieval of Search Result-1 information in ZOOM by the use of
450 options that are attached to a result set. ZOOM documentation updated
453 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
454 UTF-8 conversion. Patch by Raj Patel.
456 Added option -m to GFS to control formatting of timestamps in log file.
458 Added 'exit' as synonym for 'quit' in yaz-client
460 Added support for specifying SRW resultSetId + resultSetIdleTime in a
461 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
462 for the new members. Patch by Ko van der Sloot.
464 Added support for SRU POST. It is supported for content-type
465 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
467 Do not build the separate Multi-threaded (MT) library libyazthread.la.
468 Instead make the library libyaz.la multi-threaded. Threading as a whole
469 can still be disabled by configure option --disable-threads. Previosly,
470 with older GLIBCs there were problems with MT libs under Apache. This
471 has now been fixed a long time ago.
473 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
476 CQL module modified to be case insensitive for relations/indexes/operations.
478 Fixed bug in CQL transform code: incorrect value relationModifieder
481 Added 'show all' command for yaz-client which retrieves all results
484 Added new yaz-client, xmles, which takes a (private) OID and
485 a document to be sent as an extended service request.
487 Describe new yaz-client commands wait_response and set_auto_wait.
489 Increase TCP/IP listener backlog from 3 (which I am guessing was
490 copied from the SunOS manual entry way back when) so SOMAXCONN, so
491 that the socket will queue as many incoming connections as it's able
492 to handle ongoing connections. In other words, it will never now
493 refuse a connection that it would be able to handle merely because
494 it's not got around to accepting() enough of the pending connections
495 yet. This is the behaviour anyway under Linux, where the listen()
496 argument is ignored; but not under BSD and on systems such as
497 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
498 YAZ-based servers should now be uniform across operating systems in
501 yaz-marcdump uses 64-bit file access on some systems. This is enabled
502 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
503 This allows yaz-marcdump to read large MARC batches (>2 GB).
505 Modified all YAZ source files - except the source which is auto-generated
506 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
509 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
510 corresponding to the existing *_setl() function. These allow option
511 values containing arbitrary valuues.
513 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
514 ZOOM_resultset_sort() in new applications. Its behaviour is identical
515 except that it returns an indicator of whether or not the sort
516 criterion was accepted (0 for OK, -1 for invalid).
520 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
521 MARC output rather than returning "new" buffer.
523 yaz-client warns about unknown init options.
525 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
529 Added support for SRW sort in Generic Frontend Server. Patch
530 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
531 sortKeys - or NULL if none is provided.
533 Fixed bug #307: It was impossible to specify indefinite/no timeout
534 for ZOOM_event. Special timeout value -1 now means indefinite timeout
537 Added support for multiple languages and charsets to be specified in
538 ZOOM. Each charset/language is separated by a blank. If negotiation is
539 in effect in init-response, Option
540 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
541 Code based on patch by Vasiliy Osadchuk.
543 Fixed bug #306: infinite recursion that occurred when calling
544 yaz_log_level_init as the first call (before other log level or
547 Fixed bug in scan handling in front end server: if preferred-Position-In-
548 Response was non-present, a NULL pointer referece was performed.
552 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
553 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
554 now defined for all those error codes. So instead of putting 109 in
555 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
556 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
558 Modified the yaz-marcdump utility to skip garbage bytes between MARC
561 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
563 Program yaz-client now exits and produces an error message if multiple
564 Z39.50 servers are specified on the command line (none or one allowed
567 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
572 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
574 Fixed bug #272: Preserve spacing for CCL terms.
578 Added support for virtual hosts and multiple backend servers for
579 the YAZ frontend server. The configution is XML based and
580 support specificition of CQL to RPN mappings and explain information.
581 See section "Virtual Hosts" in the YAZ manual.
583 Extended OPAC display utility. OPAC display utility renders
584 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
585 to supplement yaz_marc_decode_wrbuf.
587 Fixed a bug in MARC decoder that could caused it to crash for some
588 invalid MARC records. More diagnostics and warnings where added in
589 XML output (warnings, etc are stored in comments).
591 --- 2.0.34 2005/02/08
593 Fixes for UNIX domain sockets. Bug #261.
595 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
597 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
598 Added yaz_marc_subfield_str which defines subfield lead string which is
599 used in YAZ_MARC_LINE format. Default string is blank+$. Added
600 yaz_marc_endline_str which defines end of fields string used in
601 YAZ_MARC_LINE format. Default string is newline.
603 Experimental support for MarcXChange. This format can be produced
604 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
605 http://www.bs.dk/standards/MarcXchange.xsd
607 Added yaz-client commands scansize that sets maximum number of
608 entries to be returned by scan.
610 --- 2.0.32 2005/01/11
612 Added support for SRW scan in yaz-client and Generic Frontend Server.
614 * Added whereInList member to SRW Scan Term.
616 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
618 Fixed NMEM system to return aligned blocks on the smallest boundaries
619 that are suitably aligned for all possible types on the particular
620 architecture YAZ is being built for.
622 --- 2.0.30 2005/01/04
624 Fixed numerious warnings that was issued with newer versions of GCC.
626 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
627 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
630 Make YAZ Generic Frontend Server slightly faster.
632 Enhance (and reduce) logging for Generic Frontend Server.
634 Revert YAZ log system so that it flushes every write operation
635 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
637 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
638 instead of LOG_, due to name clash with syslog(3). LOG_ are still
639 present. New applications should define YAZ_USE_NEW_LOG=1 - this
640 will effectively disable old definitions.
642 --- 2.0.28 2004/11/09
644 Added yaz_log_time_format which specifies log format using
647 Added yaz_log_module_level which returns mask for a module. Value
648 is non-zero mask a if module is enabled; zero if disabled.
650 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
651 in include/yaz/cql.h.
653 Fixed bug #176: Dont throw diagnostics on empty SRU args.
655 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
657 Fixed bug #172: RPM builds does not enable SSL.
659 Doxyfile.in part of dist. Doxyfile generated by configure.
661 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
662 are given and the corresponding component does not exist.
664 Extend CCL documentation in YAZ reference. Describe r=r.
666 --- 2.0.26 2004/10/01
668 Fixed MARC->MARCXML conversion to properly deal with
669 fields, subfields, indicators having non-ASCII characters.
671 Fixed MARC->MARCXML conversion so that ASCII control characters
672 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
675 Added YAZ GFS support for conversion from Z39.50 surrogate
676 diagnostics to SRW surrogate diagnostics.
678 Bug fix: YAZ GFS did not return schema in explainResponse.
680 --- 2.0.25 2004/09/30
682 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
683 now converts recordSchema to elementSetName as well as schema URI.
685 Fixed bug in COMSTACK that prevented HTTP request packages from being
688 --- 2.0.24 2004/09/29
690 Added CCL facility r=r "range" which is similar to r=o "ordered" but
691 does not require white-space before and after the dash in a range, e.g.
692 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
695 Fixed a few AC_TRY_LINK configure tests that did not operate properly
696 due to new GCC removing "redundant" code.
698 Added yaz-client commands scanpos and scanstep that sets preferred
699 position and step-size for scan.
701 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
703 Added CCL utility ccl_qual_buf which parses one or more CCL
704 spec lines in a buffer.
706 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
707 of name and value - ignoring empty lines and comments.
709 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
711 Added odr_get_element_path which returns current element path for an
712 ODR handle. This utility is useful in error handling or user-defined
715 Added ODR_PRINT utility odr_set_stream which is is a more generic
716 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
717 to a write function and pointer to close function. The close function - if
718 non-NULL - will be called during odr_destroy.
720 Fixed bug in CCL parser where truncation char was not removed from
721 right side when truncation=both was in effect.
723 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
726 --- 2.0.23 2004/08/11
728 Fix buffer overrun in CQL parser when dealing with proximity (%).
730 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
731 to UTF-8/UCS conversion is now only based on codetables.xml.
733 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
735 --- 2.0.22 2004/08/06
737 Add support for more "commit changes" in ZOOM (uses Extended Services).
739 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
742 Yet another small fix for configure of SSL.
744 --- 2.0.21 2004/05/14
746 Fix SSL libs for configure when --with-openssl=DIR is given.
748 --- 2.0.20 2004/05/10
750 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
752 SSL comstack now uses yaz.pem certificate file on server side
753 by default. Certificate filename can be configured by calling
754 comstack function cs_set_ssl_certificate_file before cs_bind is used.
756 Fix bug regarding multiple calls to ZOOM_connection_connect.
758 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
760 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
761 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
763 ZOOM now allows inspection of X509 peer certificate for verification.
764 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
766 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
767 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
768 as "modular" but it simplifies things.
770 Added cs_get_peer_certificate to that returns peer X509 PEM.
772 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
773 NULL if SSL is unavailable.
775 Documentation about MARC decoding tools.
777 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
779 --- 2.0.19 2004/03/30
781 Rename CHANGELOG to NEWS to follow GNU style packing.
783 Fix bug with missing initialization of member in init_diagnostics.
784 This bug affects threaded version of GFS server.
786 --- 2.0.18 2004/03/20
788 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
791 Ensure zlib.dll is packed with Windows install.
793 --- 2.0.17 2004/03/17
795 Fix encoding of xsd:string to use text instead of CDATA.
797 Fix endless loop in CQL parser with unbalanced ".
799 Use a more compact way to store MARC-8 conversion tables.
801 --- 2.0.16 2004/03/16 Debian only
803 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
806 Update CQL parser to use new CQL 1.1 modifiers for booleans and
811 --- 2.0.15 2004/03/01
813 Another fix for decoding of XML packed records.
815 --- 2.0.14 2004/02/25
817 Fixes for Chunked encoding. White space not ignored after length spec.
819 Update NS and use default NS for SRW diagnostic elements.
821 --- 2.0.13 2004/02/23
823 Implement ZOOM_resultset_cache_reset which resets record cache.
825 Implement ZOOM_resultset_sort which sorts a result set.
827 Implement chunked HTTP transfer.
829 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
831 --- 2.0.12 2004/02/16
833 Added member 'schema' to bend_explain_rr structure so that backend
834 can specify explain record identifier. Defaults to Zeerex 2.0.
836 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
838 --- 2.0.11 2004/02/16
840 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
843 Added init command for yaz-client which sends "extra" init request.
845 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
846 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
848 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
850 Make ZOOM error code for "invalid query".
852 Fixed compilation for SSL which wasn't properly enabled for all platforms.
854 --- 2.0.10 2004/02/05
856 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
859 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
861 Added option -p <file> to make Generic Frontend Server to write PID file.
863 Added option -D to put Generic Frontend Server in background on its own.
865 Make ZOOM C recognize option "password". If unset, "pass" is used
866 (for backwards compatibility).
868 Fixed a bug in Generic Frontend Server that could make it crash if a
869 client sets characterSetNegotation bit, but didn't pass negotiation stuff
872 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
873 Must be issued before open, in order to be in effect.
875 --- 2.0.9-6 2004/01/12 Debian/Windows
877 Make the SRU server more picky WRT unknown params, etc.
879 Bug fix: ZOOM scan response didn't return displayTerm - when present.
881 New YAZ client command, options, that sets Z39.50 options.
883 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
884 options from a string of tokens (one token for each option bit).
886 Update SRW diagnostic code messages.
888 --- 2.0.9-5 2004/01/07 Debian/Windows
890 Handle user defined stylesheet for SRW/SRU.
892 --- 2.0.9-4 2004/01/06 Debian/Windows
894 Fix bug in decoding of Content-Length.
896 --- 2.0.9-3 2004/01/06 Debian/Windows
898 Fix a bug with decoding of XML packed records.
900 --- 2.0.9-2 2004/01/05 Debian only
902 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
904 Fix bug in SRW/SRU diagnostics decoding.
908 Fixed bug in Generic Frontend Server which could drop records exceeding
909 preferred message size. Reported and fixed by Irina Dijour.
911 Fixed calculation of package size for structured records in Generic
912 Frontend Server. Reported and fixed by Irina Dijour.
914 Fixed namespace for SRW/SRU diagnostics.
916 Fixed SEGV in yaz-client that occured for HTTP connection errors.
920 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
921 this version is incompatible with version 1.0 and older YAZ SRW/SRU
924 CQL changes to reflect recent changes to the specification:
925 * Documentation talks about context sets instead of index sets.
926 * Documentation talks about indexes instead of qualifiers.
927 * The CQL-to-PQF transformer's configuration file now uses
928 "index.set.name = <attributes>" instead of the old form
929 "qualifier.set.name = <attributes>". (Both forms are still
930 understood but the latter is deprecated.)
931 * CQL terms with no explicit index specified are now interpreted as
932 cql.serverChoice instead of srw.serverChoice (which of course
933 behaves exactly the same.)
937 MARC conversion can now generate ISO2709 output in another
938 character set. yaz-marcdump uses this facility if you invoke it
941 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
942 functions from there can be used from C++.
946 Frontend server now transfers memory from decoded packages to stream
949 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
950 references to show up.
952 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
953 the ZOOM Abstract API. The older names for the same options are still
954 also supported for the benefit of old applications.
956 ZOOM-C supports "implementationId" and "implementationVersion" options
957 to go along with "implementationName". These allow the user code to
958 specify identification strings to be sent to servers.
959 Add OID for the new ExtLite attribute set.
961 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
962 as requested/supplid by Ere Maijala <ere@atp.fi>
964 For generic frontend server, reverse the order of
965 "toolkit-supplied / application-supplied" strings sent as implementationId,
966 Name and Version. Also, remove the spaces around the slash. This brings
967 the GFS in line with the behaviour of ZOOM-C on the client side.
969 Add function ZOOM_scanset_display_term.
971 yaz-client shows scan displayTerm if present.
973 Utility yaz-iconv is now installed by default along with the man page
976 Extend configure check for OpenSSL to use pkg-config where available (such
979 Incorporate patch by Morten Bogeskov which allows a Unix file socket
980 server to specify uid/gid/mask for socket using the format
981 unix:[user=uid,][group=gid,][umask=mask,]file=path
982 If file= is omitted the existing format is assumed, e.g.
984 in which case the mask is 0666 (rw for everybody).
986 Major restructure of YAZ source. All source in libyaz is in src directory.
987 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
988 util (utility programs such as ASN.1 compiler, yaz-marcdump).
990 Added man page for utility yaz-marcdump (used to be called marcdump).
991 yaz-marcdump is installed by 'make install'.
993 Fixed a memory leak in Generic Frontend Server that occurred when decoding
994 of incoming package failed.
996 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
998 Change prototype of odr_perror: add const to message string.
1000 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1002 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1003 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1004 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1005 DNS lookup. There should not be any compatibility problems with this
1006 assuming that blocking=1 or 0 is used.
1008 Fix bad reference in UNIX comstack in function cs_addrstr.
1010 Fix for compilation on AIX.
1012 The generic front-end server (server/seshigh.c) now supports returning
1013 Init diagnostics to the client in User-information-field, in
1014 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1017 --- 2.0.4 2003/09/04
1019 Allow any CQL relation (not just all,any,exact,scr).
1021 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1022 that features the same UI.
1024 Implemented command update0 in YAZ client which is equivalent to
1025 update but uses old of Ext Update ASN.1.
1027 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1028 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1029 Previously no OID was used for this info.
1031 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1032 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1033 returns 'malformed search term' otherwise.
1035 SortResponse member resultCount now set to NULL in sort handler of
1038 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1041 Add three new utility functions for translating OIDs between various
1042 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1043 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1044 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1045 char *oid_to_dotstring(const int *oid, char *oidbuf);
1046 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1048 Reverted modifications for ES Update definition for z_IU0Update
1049 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1050 is back to YAZ 2.0.2.
1052 String value attributes for CCL parser.
1054 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1055 which their FirstSearch server returns in Init responses, sometimes
1056 carrying useful diagnostic information when Init fails. This has the
1057 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1058 "z39.50/oclcui.asn", where its definition is somewhat different from
1059 what OCLC document on their web-site, as required to interoperate with
1062 Support for anonymous authentication in yaz-client. Use the command
1065 * Fix the OID of the Index Data-local "admin" Extended Service from
1066 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1067 the 1000, which indicates a locally-defined OID, was a mistake.
1069 --- 2.0.3 2003/06/20
1071 Fix CCL directive @case handling so that it affects string match for
1072 both CCL keywords and qualifiers.
1074 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1075 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1076 Decoder has been updated with ASN.1 changes as listed in
1077 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1078 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1079 z_IUUpdate, remains unchanged.
1081 ZOOM_record_get may now return a record in a specific character set.
1082 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1083 "from" is the character set of record as returned by target. "to" is
1084 the character set to be returned. If omitted, "to" is UTF-8.
1086 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1088 New ODR utility, odr_getelement, which returns name of element for
1089 which encoding/decoding failed.
1091 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1092 in cases where a required element was omitted.
1094 Bug fix: some MARC8 sequences were not converted.
1096 New ZOOM option "step" which specifies number of records to be
1097 retrieved in one chunk. Used in conjunction with "start" and "count".
1099 SRW support for yaz-client. Use scheme http: to use it, e.g.
1102 yaz-client no longer does (un)intelligent character set conversions
1103 by default. Can be enabled with charset and marc_charset commands.
1105 xmalloc trace fix for 64-bit systems such as DEC alpha.
1107 Solaris 2.6 compile fix.
1109 New function, cql_strerror() translates SRW error codes, as returned
1110 by cql_transform_error(), into human-readable English strings. Used
1111 in yaz-client diagnostics when appropriate.
1113 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1114 converts it into a type-1 query which is sent to the server. This
1115 makes CQL available for use with all Z-servers, as opposed to the tiny
1116 minority that can handle CQL queries themselves.
1118 --- 2.0.2 2003/04/28
1120 New Debian package layout similar to the Redhat Package layout.
1122 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1123 and search result respectively.
1125 --- 2.0.1 2003/04/25
1127 Redhat package is now several packages: libyaz (runtime libraries),
1128 libyaz-devel (development and documentation, and yaz (utility programs).
1129 Package spec file by Morten Bøgeskov.
1131 New member 'schema' in struct bend_fetch_rr which the name of requested
1132 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1133 handler MAY set this to reflect the schema of the returned record.
1135 New member 'display_term' in struct scan_entry. GFS now sets member entries
1136 and allocates scan entries to be filled by user scan handler. In previous
1137 version, entries member was allocated by the scan handler. That still works,
1138 but the GFS will ignore member display_term - assuming it was NOT set by
1139 the handler. The fact that the GFS now allocates the entries both allows
1140 for new members and makes a scan handler easier to write.
1142 Fix CQL lex buffer overflow.
1144 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1145 SRU default recordPacking is string.
1147 SRU protocol support for frontend server.
1149 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1151 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1153 Added scan for the ZOOM shell (zoomsh).
1157 * String Identifers for Schemas (Amendment 5).
1158 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1159 Old definition for schema
1160 Odr_oid *schema; /* OPT */
1165 Z_InternationalString *uri;
1166 #define Z_Schema_oid 1
1167 #define Z_Schema_uri 2
1170 * resultCount parameter to Sort Response (Amendment 1).
1171 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1173 Support for SRW 1.0 over HTTP. This is an optional feature and
1174 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1177 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1178 on the same port. SRW SearchRetrieveRequests are mapped
1179 to bend_init,bend_search,bend_fetch,bend_close.
1181 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1183 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1184 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1186 ZOOM connections are SRW based if schem http is used for hostname
1187 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1188 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1190 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1191 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1192 distance=n, order=true/false, relation=le, prox unit=word. If
1193 n is omitted, distance 1 is used.
1195 Fixed problem with C compiler include path in wrong order.
1197 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1198 on Solaris. Patch from Ko van der Sloot.
1200 New MARC decode API. All new functions operate on a yaz_marc_t
1201 handle. The most important new functions are: yaz_marc_create,
1202 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1203 decode and destroy respectively. Decoder can produce formats
1204 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1205 include/yaz/marcdisp.h.
1207 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1208 to UTF-8, UCS-32, wchar_t or Latin-1.
1210 * Prototypes for yaz_iconv_-functions moved to separate header
1211 include/yaz/yaz-iconv.h.
1213 Make a few private functions 'static' in unix.c. This prevents
1214 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1216 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1217 are set when Init Response is received.
1219 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1220 but returns diagnostic set as well.
1222 New function yaz_strerror which is a portable wrapper for
1223 strerror/strerror_r/GetLastMessage.
1225 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1226 is returned for MARC. If type is "oai", then OAI MARC is returned.
1228 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1231 --- 1.9.2 2002/11/26
1233 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1235 Fix bad race conditions on SIGTERM and terminate gracefully in
1238 Move retrieval (data1) module to Zebra since nobody seems to be
1241 Add GRS-1 render for ZOOM using same format as yaz-client.
1243 --- 1.9.1 2002/10/05
1245 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1247 Fix broken ESpec handling in data1 module.
1249 SGML reader parses comments and makes them part of the data1 tree.
1251 Added several type casts so that YAZ compiles as C++ code.
1253 ZOOM didn't handle PDU encoding failures properly.
1255 Added more Bib-1 diagnostics (approved extensions).
1257 GNU configure: better check for iconv.
1259 More portable use of accept, getpeername. Check for socklen_t. Use
1260 int/size_t if socklen_t is not defined.
1264 PQF parser rejects bad queries - including those with extra
1265 characters in them. PQF parser used to silently ignore that.
1266 Cleaner API for PQF added, which allows you to get detailed
1267 error information for bad queries (see yaz/pquery.h).
1269 Fixed bug in ZOOM_record_get for type "database".
1271 Implemented mini iconv library supporting conversions between
1272 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1274 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1276 --- 1.8.9 2002/08/20
1278 Fixed ZOOM C record cache so that preferredRecordSyntax and
1279 elementSetName is used to check for already fetched records.
1281 --- 1.8.8 2002/08/02
1283 Added three members in bend_initrequest structure to facilitate
1284 character set negotiation.
1286 Fixed a bug in frontend server that could cause indefinite
1287 loops under rare conditions.
1289 Revised character set utilities (charneg.h) so that encoding
1290 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1292 For PQF, directive @term <type> sets term type for Scan/Search.
1293 Here <type> is general, string, numeric, null. The term type
1294 is inherited - just like @attr.
1296 New call odr_set_charset that sets character set conversion for
1297 international-strings on a ODR stream. Prototype is:
1298 int odr_set_charset(ODR o, const char *to, const char *from);
1299 The InternationalString is still represented as C string in YAZ
1300 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1301 won't). On the protocol level, you can use any encoding.
1303 Support for UNIX sockets in ZOOM.
1305 Solaris recv sometimes returns errno == ENOENT. It is treated as
1306 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1308 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1309 both client and server. Code by Morten Bøgeskov.
1311 --- 1.8.7 2002/05/22
1313 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1314 that they can be used directly from Visual Basic. You must recompile
1315 your windows APP if you're using ZOOM.
1317 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1318 Commands "lang" and "charset" sets language and character set respectively.
1319 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1320 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1322 Attributes from multiple CCL fields may be OR'ed rather than merged
1323 using directive "@field or". Fields are still merged by default -
1324 equivalent to "@field merge".
1326 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1329 Fixed bug in zget for parameter ExtendedServicesResponse.
1333 --- 1.8.6 2002/03/25
1335 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1337 Client displays USR.1:SearchResult-1 (hits per term).
1339 Additional Search Info for search in Generic Frontend Server.
1341 Fixed CCL parsing of "field=s".
1343 WIN32 installer - using the excellent NSIS software from nullsoft.
1345 Fixed CCL parsing of "field = - <number>".
1347 Added function yaz_marc_decode that decodes MARC for line mode
1348 display or XML (similar to that used by JZKit).
1350 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1351 Z39.50. But ISO/ILL was, however.
1353 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1354 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1357 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1359 --- 1.8.5 2002/02/03
1361 New YAZ client features: Command completion and new commands:
1362 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1363 Code provided by Jacob Poulsen.
1365 New call oid_trav, that visits all registered OIDs via callback.
1367 Function ZOOM_record_get now returns const char pointer rather than
1368 void pointer. It saves a lot of type casts.
1370 For YAZ client, command "auth" now allows you to set authentication
1371 in IdPass style. It is enabled when three tokens are given - order
1372 is user, group and password.
1374 Fix memory leaks in MARC record handling for ZOOM.
1376 New option for YAZ client, -k <kilobytes> that sets
1377 maximum record size. Similar to -k option for generic frontend
1378 server and yaz-ztest.
1380 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1382 Prefix query parser reports "fail" when bad attribute set is given.
1384 Fix in MARC decoder. Proximity logging. Fix for attribute set
1385 in scan handler for server. Patches by Shigeru Ishida.
1387 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1390 Configure option --with-openssl=<dir> now works when a directory is
1391 specified. Patch provided by Morten Bøgeskov.
1393 New option for YAZ client, -u <auth>, that sets authentication.
1395 ZOOM fix: error information was sometimes "missing", since error
1396 was cleared/reset too when it shouldn't.
1398 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1400 --- 1.8.4 2002/01/04
1402 Scan for ZOOM API. New object ZOOM_scanset. New functions
1403 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1404 ZOOM_scanset_destroy.
1406 New ZOOM function, ZOOM_connection_last_event, that returns type
1407 of last event (such as "receive data", "send data", "apdu received",
1410 New ZOOM option, schema, that specifies schema for retrieval.
1412 New CCL feature. Qualifiers can be aliases for one or more
1413 other qualifiers (if more than one is given, OR is used).
1415 ZOOM uses named result sets if target supports it.
1417 Two new YAZ client commands: . (dot, which sources a script of YAZ
1418 client commands), and ! (to execute shell command.). Implemented
1421 Working on Debian packages.
1423 --- 1.8.3 2001/11/19
1425 YAZ client enables named result sets only if target supports it.
1427 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1429 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1430 with key="host" to get same result.
1432 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1433 Function Z3950_resultset_record(s) returns references to records
1434 "owned" by resultset. To become owner use Z3950_record_clone.
1436 Function z_ext_record handles Extended Services. Thanks to
1439 --- 1.8.2 2001/11/12
1441 CCL Parser fix: ignore token comma when dealing with and-lists.
1443 Documentation updates for COMSTACK.
1445 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1446 Changed prototype Z3950_records. For some functions, int parameters
1447 were changed to size_t.
1449 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1452 New MARC decode/display function, marc_display_exl, which properly rejects
1453 non-ISO2709 records. YAZ client uses it.
1455 --- 1.8.1 2001/10/29
1457 Fix bug: local attribute set wasn't set correctly in PQF strings.
1461 * Old Z39.50 codecs no longer supported.
1463 Added ZOOM C binding. See http://zoom.z3950.org/
1465 Renamed states for COMSTACKs to avoid confusion with events.
1467 Implemented cs_look and proper cs_rcvconnect.
1469 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1471 Configure detects POSIX threads on OpenBSD.
1473 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1474 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1476 When error is returned from present handler, non-surrogate diagnostic
1477 is returned in present response (and fetch handler is no longer called).
1479 * Minor adjustments to pquery parser (PQF). Token characters may be
1480 escaped by using backslash (C-style).
1482 PQF parser allows string attribute values to be specified. For @attr,
1483 non-numeric characters after the equal-sign are treated as strings
1484 (e.g. @attr 9=title).
1486 CCL trunction character may be defined (@truncation in file)
1488 * function zget_ExtendedServicesRequest sets waitAction to
1489 waitIfPossible (was wait).
1491 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1494 CCL operator names may be set in field definition files (CCL_bibset).
1495 See ccl/bib1 for an example.
1497 Fixes in ASN.1 compiler for C++ compatibility.
1499 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1500 and "op_or" to avoid conflict with C++.
1502 Fixed problem with GNU readline detection on Redhat 7.0.
1504 Added step-size for Scan backend handler.
1506 Fixed bug that made the frontend server crash when no attribute
1507 set was specified for scan.
1509 Front-end server automatically switches to original working directory
1510 when installed as an NT service. Previously -w had to be specified to
1513 Added extended attributes for retrieval module (data1), so that data1
1514 records carry d1_readXML/SGML attributes. d1_read also supports
1515 null-data rules ( <tag/>)
1517 On UNIX when POSIX threads are available, a separate library libyazthread
1518 is created. Programmers should link with that library and the yaz library
1519 when using threads. The reason for the split was that some applications
1520 on Linux, such as Apache, doesn't work well when using shared objects that
1523 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1524 (or any frontend server) in SSL mode by specifying ssl: followed by
1525 address. Only tested on UNIX.
1527 Added feature for CCL module. Virtual structure s=al or s=ol generates
1528 and-list and or-list respectively instead of phrase search.
1532 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1533 log_mask_str. This was done to avoid name conflicts with other libraries
1534 (such as other PHP extensions).
1536 Added raw OID member for preferred record syntax (request_format_raw)
1537 and returned record syntax (output_format_raw) for backend fetch method.
1539 Config file yaz-config now accepts options so that it returns specific
1540 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1542 Shared library support for UNIX using GNU libtool.
1544 * Modified backend interface. Request/Response struct's replaced by
1545 one read/write C struct. For example bend_fetchrequest and
1546 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1547 Every handler - even search has to be registered in bend_init
1548 handler. This means that the YAZ library no longer refers to
1549 external functions and it makes it possible to make the whole
1550 thing a single DLL/SO.
1552 Added Segment handler for backend server.
1554 Added Zmbol/Zebra administrative functions to YAZ client.
1556 Threaded frontend server on UNIX (when POSIX Threads are available).
1557 Starting the server with option -T enables multi-threading.
1561 Added configure option --enable-comp/disable-comp to control use
1562 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1563 located in sub directory asn.
1565 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1566 in ${exec_prefix}/bin along with the other programs yaz-client and
1569 GNU automake used to maintain makefiles.
1571 Added several OID's.
1573 Changed retrieval module so that we can load records with no abstract
1574 syntax defined. Tagpaths in these records are fully composed of string
1577 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1581 On UNIX, the generated makefile now supports a proper 'make install'.
1582 The prefix can be set via GNU configure to set the install location
1583 (default is /usr/local).
1585 * YAZ programs client and ztest were renamed to yaz-client and
1586 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1587 locations, such as /usr/bin,/usr/local/bin,etc.
1589 * YAZ Header files were moved from include to include/yaz. YAZ Header
1590 files are referred to as include <yaz/log.h> rather than <log.h>.
1591 The YAZ include path (-I ..) is therefore the same as before. Programmers
1592 should update their #include statements or use -Ipath/include/yaz
1593 instead. The main motivation for doing this change is that YAZ header files
1594 can be installed in "standard" locations /usr/include,/usr/local/include
1595 without introducing conflicts, since ALL YAZ header files are stored
1596 in subdirectory yaz (under /usr/include for example).
1598 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1599 rather than project/workspace files. We switched because project files
1600 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1603 Changed name of logging function, logf, to yaz_log, to prevent name
1604 clash with some math-log functions. The YAZ header log.h defines logf
1605 to yaz_log (#define) so there should be no incompatibilities by this
1608 Added bend_start/bend_stop handlers for server. These handler are
1609 called on start/stop of server. For windows they are called whenever
1610 a service is started/stopped.
1612 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1613 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1614 in util/yc.tcl. The auto-generated C code structures are, in a few
1615 cases, incompatible with the old decoders. There are differences in the
1616 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1617 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1618 The preprocessor variable ASN_COMPILED is defined when the compiled
1619 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1620 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1621 wish to use the old encoders/decoders you can specify --disable-yc
1624 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1625 version so that it supports both new - and old version of DB Update
1627 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1628 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1629 change. The name parameter can be set to 0 in which no name is specified
1630 for the construction. The macros odr_implicit and odr_explicit sets name
1631 parameter to zero for the construction involved. New macros
1632 odr_implicit_tag and odr_explicit_tag are similar to the others,
1633 except that a name parameter is added. For programmers' that don't use
1634 ODR they probably only need to change the call to z_APDU and z_External.
1636 Added access control facility by interfacing the TCP wrapper library.
1637 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1638 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1639 name of the daemon and enables the access control as specified in
1640 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1642 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1643 den Dool <H.M.vdnDool@kub.nl>.
1645 Added reference ID parameter to most functions in server API - refer
1646 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1648 Changed name of ccl library to libccl.a (was ccl.a).
1650 Fixed bug in decoder for Explain (Category TargetInfo).
1652 Added support for GNU readline in client. Thanks to Jacob Poulsen
1653 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1655 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1656 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1657 IMPLEMENTATION! This change was made to the development version before
1658 the ZIG decided to retract the amendment. If any users MUST be
1659 compatible with the original Update definition, PLEASE CONTACT US, and
1660 we will include a separate definition corresponding to the old Update
1661 ES. Note that because of the change to the ASN.1 of the
1662 TaskPackageRecordStructure we cannot define a single structure that
1663 will support both versions.
1665 * Added const modifier to buffer parameter for some ODR/BER encoding
1666 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1667 completeWAIS, odr_dumpBER.
1669 Fixed bug in client.c which caused a crash when a scanResponse didn't
1670 contain positionOfTerm.
1672 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1673 * will cause an error in a client if a non-YAZ target sends both a
1674 * list of Scan entries and non-surrogate diagnostics.
1676 Retrieval module enhancements. Tag sets may be typed in the reference
1677 to it. From the .abs-file the "tagset" directive takes a third optional
1678 integer type for the tag set referenced. From a .tag-file the "include"
1679 directive takes a third optional type as well. The old "type" directive
1680 in the tag set itself is still recognized but acts as the default type
1683 Backend interface change. Individual Scan terms returned from bend_scan
1684 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1685 in include/backend.h.
1687 Retrieval module enhancements. Multiple tag sets and attribute sets may
1688 be specified in abstract syntax specs. Revised the error/warning for
1689 logging messages reported by the retrieval module when reading the
1692 Object Identifier system (oid_..) changed. The API is backwards
1693 compatible but the oid-routines now allocates new OID's when needed.
1694 Raw OID's may be specified in oid_getvalbyname.
1696 YAZ now uses GNU configure to generate Makefile(s).
1698 * Minor changes in some of the member names of DeleteResultSetRequest and
1699 DeleteResultSetResponse. See include/proto.h.
1701 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1702 and added member 'languages' in TargetInfo (which was missing).
1704 Changed the way attribute sets are handled in the retrieval
1705 module. These are now cached, just like the abstract syntaxes
1708 Changed YAZ so that it links with compiled ASN.1.
1710 Added Explain-schema definitions and mapping routines. The following
1711 Explain categories have been implemented: AttributeDetails,
1712 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1714 Fixed minor bug in Windows version of Server Library.
1716 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1718 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1720 Added EXTERNAL: UNIverse Resource Report (non-standard).
1722 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1723 ENUMERATED and SET OF.
1725 * Added 'const' to some of the char pointer arguments for the
1726 functions, data1_read_node, data1_getelementbytagname,
1727 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1730 Fixed bug in data1_insert_taggeddata - the last_child member of
1731 parent wasn't initialised.
1733 * Changed data1_read_record and data1_read_node so that the supplied
1734 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1735 doesn't refer to any parts of the "SGML"-buffer.
1737 Fixed bug in server library (Windows version of statserv_remove).
1739 * Changed code so that it compiles as C++. The type definition
1740 of Odr_fun which is a member of Odr_arm was changed. The result is,
1741 that an explicit typecast is needed for the fun pointer when
1742 using Odr_arm - as in:
1743 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1745 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1747 Implemented the new structured date and time definition as approved
1748 by the ZIG. Added schemaId element to the specificTag in Espec-1
1749 (also approved at the last ZIG). Thanks to RVDM.
1751 Added some Object identifiers (RVDM).
1753 Changed the Update Extended Service (RVDM).
1755 Added command "refid" to client which specifies referenceId for
1756 the following requests.
1758 Implemented extended service handling for server. See ztest.c
1759 for an example as well as backend.h. New handlers are registerd
1760 in the Init handler.
1762 * Changed interface for sort in server.
1764 Added new members to statserv_options_block. It allows a server
1765 to read options from another source than just the command line. Thanks
1766 to Charles Woodfield.
1768 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1769 renamed to zboolean. Some C++ compilers complained about the name.
1771 Minor changes to gils.abs. Added index 's' (sort) on title
1772 and date/time-last-modified.
1774 --- 1.4pl2 1998/1/30
1776 Fixed bug in server library regarding inetd mode (-i). This bug
1777 was introduced by release 1.4.
1779 --- 1.4pl1 1998/1/29
1781 Added sort facility in client and backend server interface.
1783 Fixed problem with dependencies in Makefile(s).
1785 Fixed bugs for encoders/decoders of extended services and
1788 Implemented sub-tree feature for schemas. Sub-trees are
1789 referenced in *.abs-files. See explain.abs for an example
1790 of the use of this feature.
1792 Modified bib1.att; local attributes for ANY didn't include
1793 ANY itself (only affects use of the retrieval module).
1795 Fixed bug in plain SGML reader in function data1_read_node:
1796 tags with prefix "var" was incorrectly interpreted as variants.
1798 Added feature "sub-schemas" to enable references to - and definitions
1799 of - group of elements.
1801 * Removed member parent from type data1_element (in data1.h).
1803 Implemented function odr_nullval() that returns the value of
1806 * Removed member num_children from data1_node (in data1.h).
1808 Made NT service interface part of the server library. The
1809 function statserv_main uses the NT service when required and
1810 calls the statserv_start / statserv_close routines.
1812 Routine zget_SearchRequest and zget_PresentRequest fills
1813 resultSetName/Id member with "default" instead of "Default".
1815 Fixed memory leak in server. Request queue member wasn't freed.
1817 Fixed nmem_exit so that memory is freed.
1821 Revised the CCL parser utility to be thread safe.
1823 Added function, oid_ent_to_oid, to replace the function
1824 oid_getoidbyent, which is not thread safe.
1826 * Added nmem_init and nmem_exit to initialize and release
1827 NMEM resources. Function nmem_init should be called once in the
1828 initial thread before NMEM/ODR is used. statserv.c and client.c
1829 have been changed accordingly. The change was necessary to make
1830 NMEM thread safe. The NMEM memory pool is shared amongst threads
1831 in a process. Unix-based applications will still work fine without
1834 Added NT Services interface for the the Z39.50 (statserv) Server.
1835 Refer to the ztest.c source on the usage.
1837 Windows 95/NT port using MSVC5.0. Project files are included in the
1840 * Defined new 'global' handle for the retrieval (data1) system. The
1841 new handled, data1_handle, describes the state of the data1 system.
1842 This handle is passed as first argument to virtually all
1843 data1 related routines. The functions data1_create and data1_destroy
1844 creates and destroys a data1 handle respectively.
1846 Added ODR encode stream member to all backend request structures
1847 init, search, scan etc. This stream should be used to allocate all
1848 memory used for the response when thread safe operation is needed.
1850 Changed the comstack utility, cs_addstr, to be thread safe. The
1851 returned hostname string returned by the function is now part the
1854 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1855 function. The cs_straddr takes a COMSTACK handle as argument, so this
1856 function must be used after cs_create and before bind/connect.
1857 This function is thread safe.
1859 Moved test server to 'ztest' directory - generic server code still
1860 in 'server' directory.
1862 Made prefix query (pquery.c) utility thread safe.
1864 Added new function modifier YAZ_EXPORT to 'export' public DLL
1865 functions when using windows (see include/yconfig.h).
1867 Added definitions to the OID database (util/oid.c) (RVDM).
1869 Added new BIB-1 diagnostic messages to the handler diagbib1_str.

1877 With input from RVDM.
1879 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1880 Thanks to Ronald van der Meer (RVDM).
1882 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.

1887 Added optional, physical ANY (key replication)
1889 Fixed null-reference problem in GRS-1 output filter.
1891 Proximity operator added to Prefix Query Format (PQF).
1893 In test client command "base" accepts multiple databases.
1895 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1899 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1901 Smallish bug-fixes in the new encoders/decoders (explain).

1918 --- 1.2 1996/6/10 (1st anniversary release)
1920 Added Summary record syntax. Lightly tested.
1922 Added OPAC record syntax. Untested.
1924 Added ResourceReport service encoders/decoders. Untested.
1926 Fixed bug in z_Unit - wrong tagging on unitSystem.

1937 surrogate diagnostics were generated.
1939 [retrieval] Allow multiple local values for attribute.
1941 [retrieval] Allow multiple attributes per element in .abs files. index type.

1945 --- 1.1pl2 1996/4/10
1947 Minor changes, mostly specific to Zebra's requirements (retrieval)
1951 Repaired bug in frontend server when running multiple listening
1952 endpoints in dynamic mode.
1954 z_External() now won't break if a known, ASN.1 value comes encapsulated
1955 in an octet-string. The value will pass through unmodified in an Odr_oct.
1957 Added a bit of code to the demo client to decode & display
1958 ASN.1-structured records represented in the octet-aligned branch of
1959 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1961 Added z_ext_getentbyref() to the ASN module. Doc updated.
1963 * Completed the SCAN definition in the ASN module. This may break SCAN
1964 code based on older YAZ-versions at compile-time. The fix is easy -
1967 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1968 under the SCAN definition. Remember to initialize this, server-people.
1970 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1971 that this does not extend to ODR and ASN.
1973 Comstack allows insertion of established socket (primarily for
1974 inetd-operation of servers). Doc updated.
1976 Front-end server can now start from the inetd in TCP mode. Doc
1979 --- 1.0pl4 1996/1/24
1983 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1984 the rank and record number.
1986 Adjustments to the frontend server.
1988 Fixed diagnostic BER dumper. It ignored the file argument.
1992 Various changes to retrieval module.
1994 Changed the union discriminators of the protocol files from enums to
1995 ints paired with #defines.
1997 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2000 *Changed operator in the RPN structure to 'roperator', again to avoid a
2003 Fixed problems in Explain decoders/encoders.
2005 --- 1.0pl2 1995/12/6
2007 Memory bug in log module fixed.
2009 --- 1.0pl1 1995/12/5
2011 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2013 Bug in Explain DatabaseInfo module fixed.
2015 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2019 The shift to v1.0 signals that we now consider the *core* functionality
2020 of YAZ reasonably stable (the core being more or less equivalent to
2021 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2022 tested (Explain not at all - though that will happen soonish).
2024 Minor changes to code to support Windows port.
2026 Various minor changes after we're getting to use GRS-1 & co. more.
2028 Added Espec-1 format.
2030 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2031 of the protocol and it cannot be selected when encoding (maps into 'string'
2032 when decoding). Needed to talk to some servers.
2034 Demo client can request simple element set names.
2036 Added Diagnostic Format encoders/decoders.
2038 Added simple Close handling to frontend server (no hooks for resource
2039 reporting yet), and demonstration client.
2041 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2043 --- 1.0b3 1995/08/24
2045 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2046 handled incorrectly when records were requested in the searchResponse. This
2047 will only affect you if you use the frontend-server.
2049 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2050 Test-client will ask for and print GRS1. Ztest will return dummy records
2053 Added Explain encoders/decoders to the service-level API. Untested.
2055 Added Extended Services: Item Order encoders and decoders to the Service-
2056 level API. Untested. We could use a recent copy of the pertinent bits
2057 of the ILL protocol to add those bits.
2059 Added diagnostic format 1 encoders/decoders to the service-level API.
2062 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2063 odr_cons.c, which causes a more correct output.
2065 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2066 was always set to 0 when no records were requested in the searchRequest.
2068 * Added better external-handling. This shouldn't harm old code that
2069 *encodes* externals. It can break code that looks for a
2070 'single-ASN1-type' representation, since those types that are known
2071 are now decoded immediately. Look at the SUTRS sample code in
2072 seshigh.c and client.c. Documentation updated.
2074 Handling of structured records in bend_fetchresponse. Length -1 marks
2075 structured record, type is deduced from format field.
2077 --- 1.0b2 1995/06/27
2078 Fairly quick maintenance release to add SUTRS support.
2080 Fixed handling of SUTRS records in the demonstration client.
2082 * Added format field to the bend_fetchrequest and bend_fetchresponce
2083 structures of the backend API (frontend server). When the record is
2084 returned, the value of the format field is mapped to an OID. The
2085 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2086 of the record. The special value VAL_NONE in the bend_request means
2087 that no specific format was requested by the client. Documentation
2088 updated accordingly. Test server (ztest) will return a fixed dummy
2089 SUTRS record if your client requests SUTRS.
2091 Documentation updated accordingly.
2093 You can now set external libraries and RANLIB support in the top-level
2097 First public release.
