1 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
4 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
5 character set for bibliographic information interchange". By Giannis Kosmas.
7 Added documentation on new OID API.
11 Changes to generic frontend server interface: added new member
12 'query_charset' for bend_initrequest structure. A backend init handler
13 should set this member to its native character set for query terms.
14 When defined, the frontend server logic will announce this character set
15 to a client if the negotiationModel bit is set by the client. All server
16 implementors are encouraged to specify this. If a backend server does not
17 specify this a warning is issued using yaz_log(YLOG_WARN,..).
19 Added CCL utility to remove terms (stop words) from resulting RPN
20 tree. This is handled by functions with prefix ccl_stop_words_ .
22 New ZOOM C option, "rpnCharset", which allows client-side conversion of
25 Clean-up the CCL API. Moved some internal structures from ccl.h to
26 private header cclp.h. Changed ccl_parser_create so that a Bibset must
27 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
28 This is replaced by ccl_parser_find_str which takes a string instead.
30 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
31 libyaz.la is the core of YAZ except the generic frontend server and
32 does not depend on POSIX threads anymore. libyaz_server.la is the
33 generic frontend server facilities and uses POSIX thread functionality
34 if available. The libyaz.la no longer depends on POSIX threads because
35 the number of global structures is limited. NMEM no longer re-uses blocks
36 between threads ; it simply free's memory immediately but allocates in
37 "large" chunks as usual. We don't expect any performance penalties
38 because of this. The yaz_log system is still using a global log_level so
39 caution must be taken when modifying it with yaz_log_init_.. +
40 yaz_log_mask_str. This, however, should not cause any trouble because
41 these functions are called during initialization of application code
42 anyway. `yaz-config --libs server` returns libs for server applications;
43 `yaz-config --libs` returns libs for non-server applications.
45 New OID database - with public definitions in oid_db.h. Removed old OID
46 database including the head oid.h and definitions such as enum oid_value
47 and struct oident. The new OID database uses the same string names as
48 before but the 'protocol' is gone. There are now only two representations
49 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
50 converts from string to OID; functions with prefix yaz_oid_to_string
51 converts the other way.
53 Change to emit_term() in CQL-to-PQF query translation: when a term has
54 the /regexp relation modifier, do not process it for leading and
55 trailing "^" and "*", which have quite different meanings in regular
58 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
59 write handlers no longer carries a 'last' parameter. This will make
60 yaz_iconv flush "less" characters. A flush is performed by call to
61 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
63 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
64 removed, because function yaz_query_to_wrbuf does the same.
66 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
67 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
69 Deprecated MARC utility functions removed.
71 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
74 Branch split: YAZ_2_1_55_branch
78 Fix to ZOOM-C so that transparent reconnection is properly handled on
79 connections that are in asynchronous mode.
81 Fixed compilation on OpenBSD 4.0.
83 Large strings in GRS-1 records are now properly displayed in yaz-client.
85 Added character conversion support for "advancegreek"; based on patch from
88 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
89 sequence is met. Before the error was not set so it would be unknown.
91 Adjust yaz-marcdump MARC reader so that it skips until record separator
96 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
97 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
98 fd_set structure used as a bitmask for the FDs to be selected on.
100 Using ACX_PTHREAD macro to check for POSIX threads.
102 Fixed have-vsnprintf check.
104 --- 2.1.50 2007/02/23
106 Fixes for configure on BSD. Bug #900.
108 Added snprintf/vsnprintf wrappers for systems that don't have
109 limits (heavens forbid).
111 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
112 created before all previous tasks were completed and removed from the
113 task queue, the new task could be removed by a mistake.
115 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
117 Implemented pass-through CQL-to-PQF conversions. Bug #861.
119 Fixed bug #832: Problem with MARC/charset in yaz-client.
121 Fixed bug #668: save command line history for yaz-client.
123 Fixed bug #830: pkg-config support.
125 --- 2.1.48 2007/01/23
127 Extended ZOOM result set options with two options that may be read by
128 a client: resultSetStatus and presentStatus with values as specified for
130 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
132 Fixed bug #827: Using SSL fails on Debian etch.
134 Fixed bug #826: Weird looking chars for set of MARC records.
136 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
137 that is treated as an ItemOrder with itemRequest being an XML document
138 external. The value of "doc" is the content.
140 Extended the GFS search facility. New member of bend_search_rr
141 'estimated_hit_count' signals that hits is known to be an estmate
142 (higher or lower than real hit count). New member 'partial_resultset'
143 signals that the search was partial (hit count is lower or equal than
144 real hit count). For Z39.50, the information is stored in resultSetStatus
145 member of SearchResponse APDU. For SRU, the information is signalled
146 via SRU diagnostic 59: "Result set created with valid partial results
149 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
151 --- 2.1.46 2007/01/13
153 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
155 Added ZOOM_connection_peek_event.
157 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
158 the following new functions:
159 ZOOM_event_nonblock, ZOOM_connection_process,
160 ZOOM_connection_get_{socket,mask,timeout},
161 ZOOM_connection_fire_event_{timeout,socket}.
162 The existing blocking event handler, ZOOM_event, is a wrapper for the
163 + blocking ZOOM_event_sys_{poll,select}.
165 Implemented function ccl_xml_config which parses XML version of CCL
166 configuration (bug #798).
168 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
170 Added timings utility (yaz/timing.h)
172 --- 2.1.44 2007/01/03
174 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
177 Fixed bug #779: Rotation of apdu.log fails.
179 Fixed for character set conversions:
180 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
181 Honor G1 set in MARC-8 decoding.
183 --- 2.1.42 2006/12/17
185 Fixed bug #775: char conversion does not handle Alternative UTF-8
188 Implemented function yaz_marc_read_line which parses MARC line format
189 records. There is a wealth of formats out there. So far, this function
190 reads line records produced by yaz_marc_write_line.
192 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
193 more generic and easier to remember(!) options: -i format and -o format
194 which specifies input format and output format respectively - where
195 format is one of "marc", "marcxml", "line", "marcxchange".
197 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
198 does not print anything except warnings for records.
200 For yaz-marcdump, added support for MARC split into files (-s) with a given
203 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
204 spec, at http://www.loc.gov/standards/sru/record-update/
205 This has changed the binary layout of the following structs:
206 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
207 bend_update_rr . Patch by Ko van der Sloot.
209 Added GFS utility function bend_assoc_is_alive which returns 1 if
210 association is still alive (client is connected); 0 otherwise (client
211 closed connection). This allows busy servers to stop working for
214 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
215 been a separate piece of software. This version of ziffy has been modified
216 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
218 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
220 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
221 Client code may now interrogate options such as "init_opt_sort" to
222 find out whether the server claims to support various options.
224 --- 2.1.40 2006/11/27
226 Added utilities yaz_{set,get}_esn to set/get element set name from
229 Removed the build of libyazthread.la. The libyaz.so is the threaded version
230 of YAZ and has been so since YAZ 2.1.10.
232 Implemented ZOOM_record_error which returns error information for
233 record (surrogate diagnostic).
235 --- 2.1.38 2006/10/31
237 Updates for SRU Update by Ko van der Sloot:
238 1. Changed name from "operation" to "action"
239 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
240 versions in the code, marked as 'backward compatible'.
241 3. Added diagnostics for SRU Update.
243 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
245 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
247 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
249 For GFS, fixed problem with SRU diagnostic 'First record position out of
250 range' being issued for 0 hits.
252 zoomtst10 part of Windows Build.
254 --- 2.1.36 2006/10/13
256 Implemented yaz_filepath_comp which splits a path into file path
257 components (required by Zebra 2.0.3+).
259 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
260 BSD inspired license until now so this should not have any real impact on
261 anybody. See http://www.opensource.org/licenses/bsd-license.php
263 Fixed bug #687: Missing log lines.
265 Fixed bug #678: CQL to PQF translation does not preserve double-quote
268 Fixed bug #689: SRU diagnostics to be added.
270 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
271 whether a connection is idle (no more work do do).
273 --- 2.1.34 2006/10/04
275 Change type of optval from long to int for invocation of setsockopt with
276 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
278 Added support for specifying the max log file size for the Generic
279 Frontend Server. The size is given with option -r.
281 --- 2.1.32 2006/09/21
283 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
285 --- 2.1.30 2006/09/17
287 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
290 Fixed bug in Generic Frontend Server that could cause a server to stop
291 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
293 For the generic frontend server, the maximum record size is used as maximum
294 size of incoming packages (SRU + Z39.50). The value until was previously
295 only used in Z39.50 Init negotiation and, later, in a session controlled
296 sizes of records returned. This is controlled using -k option. It can be
297 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
299 --- 2.1.28 2006/09/04
301 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
304 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
306 New option for yaz-marcdump -lpos=value which allows setting a portion
307 of MARC header to a certain value.
309 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
311 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
312 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
314 --- 2.1.26 2006/08/15
316 Fixed problem with SRU mode type (soap, get, post) for yaz-client
319 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
321 --- 2.1.24 2006/08/08
323 Fixed MARC ISO2709 encoding routines to deal with character set
326 Minor changes to GFS logging. Database included in search request log
329 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
330 cached/multiple records.
332 Shared libraries are built by default on Unix+configure.
334 Changed cql2pqf transformation to use a different evaluation order. The
335 new order is: always, relation, structure, position, truncation, index
336 and relationModifier. Old order was: always, relation, relationModifier,
337 structure, index, position, truncation. Note that the the latter ones
338 override former ones for identical attributes.. The new scheme means that
339 it is possible to override any existing attribute with a relationModifier.
340 And also that it is possible to override everything for the index rule
341 (except the ones listed in relationModifier). No order is perfect but this
342 one, we believe, covers more real cases.. The "always" should have been
343 called "default", since the attributes there can be overridden with all
346 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
347 compilation phase, but also for yaz-config --cflags output. This allows
348 us to have public headers with Libxml2 stuff in them . It should also,
349 eventually, make Libxml2 checks redundant in packages using YAZ, such
352 --- 2.1.22 2006/06/15
354 Changed SRU update structure bend_update_rr so that SRU diagnostics are
355 stored in uri, message and details.. Previously diagnostics were stored
356 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
357 compatibility.. but he's probably the only one affected, so.
359 Added support for CCL, compiled on the client side, in ZOOM-C. This
360 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
361 input; the resulting query objects can be used for for searching with
362 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
364 YAZ' configure searches for OpenSSL by default.
366 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
367 SL_CTX_use_certificate_file. See
368 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
369 for more info. Thanks to Ko van der Sloot.
371 --- 2.1.20 2006/06/02
373 Bug #600: SRU GET, POST support for yaz-client. Introduced
374 command 'sru' which selects method SOAP/GET/POST.
376 Allow missingValueAction to be specified for the sortspec string -
377 function yaz_sort_spec. By default, the missing value action is null.
378 Use ! to specify "abort". Use = followed by stringvalue to specify default
381 Ensured that Present-handler (if defined) is called in GFS before any call to
382 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
383 searchRetrieve requests.
385 Documentation for YAZ is now based on the Docbook XML/XSLT using
386 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
387 is no longer depending on jade/openjade or docbook-to-man scripts.
388 PDF is no longer part of the distribution - but can optionally be
389 made using DSSSL/jadetex or FOP.
391 Added retrieval handling support in Generic Frontend Server to support
392 conversion between MARC/XML as well as XSLTtransforms. See
393 etc/yazgfs.xml for an example.
395 Added Authentication support to Generic Frontend Server in SRU
396 mode. Authentication using HTTP Basic is supported, as is the use
397 of 'x-username' and 'x-password' parameters in the request itself.
399 Added support for a new character set MARC8s identical to MARC8 except
400 that it converts combined characters to single Unicode characters in the
401 Latin-1 range (when possible).
403 --- 2.1.18 2006/04/24
405 ASN.1 compiler 0.4: generates brief Doxygen file header for
406 generated .h/.c files.
408 Utility yaz_iconv now supports conversion to MARC-8.
410 New facilities for the MARC module. The reading - and writing of
411 content are separate methods for the yaz_marc_t handle. The following
412 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
413 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
414 format). Write functions have prefix yaz_marc_write_.. The existing
415 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
416 available. Removed support for OAI-MARC and simplexml (not the
417 simplexml from PHP5).
419 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
420 to be returned for this connection.
422 --- 2.1.16 2006/03/31
424 Allow multiple languages and charsets to be specified with
425 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
426 negcharset iso-8859-1,utf-8
428 Translation of proximity nodes from CQL into PQF now works.
430 Moved to automake 1.8, 1.9.
432 Added function yaz_log_set_handler which allows a log handler to be
433 installed. This handler will be called for all log messages. Output
434 to file is also produced; but that can be disabled by passing NULL
435 fname to yaz_log_init_file.
437 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
439 For SRW (including GFS), accept application/soap+xml as content-type
442 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
443 produces NO stylesheet reference even if a default stylesheet is specified
446 --- 2.1.14 2006/03/14
448 Updated Windows package to include yazd.dll + yazd.lib for the
449 Development component.
451 If the environment variable YAZ_LOG is set, then it is used as a
452 string indicating the default level of logging to use if not
453 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
454 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
455 used as before. So, for example, to omit warnings from YAZ logging,
458 cql_transform() now map structure and other attributes before indexes,
459 so that index-specific structures and other attributes can override
460 defaults. So now a combination of mapping specifications such as:
462 index.dc.date = 1=date-modified 4=5
463 does the right thing.
465 cql_transform() now also respects the "always" mapping specification,
466 which establishes an initial set of attributes to be used for all
467 terms except where overridden by more specific attributes associated
468 with the index, relation or modifier.
470 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
471 which mode to use; one of "post", "get" or "soap" (SRW, default).
473 Fixes for yaz_iconv routines: changed trie-based character set conversions
474 to use only non-negative values for bit fields due to Sun's C compiler not
475 supporting negative values.
477 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
478 sequences where not read correctly. Fix by Rustam Usmanov.
480 Updated win/makefile to use options, settings which makes things
481 compile with VS C 2005.
483 --- 2.1.12 2006/02/01
485 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
487 In ZOOM socket code, use select instead of poll on MacOSX.
489 ZOOM-C now support client-side compilation of CQL into RPN that is
490 sent to the server, enabling CQL to be used against all Z39.50
491 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
492 ZOOM_query object, and submit it using ZOOM_connection_search().
493 The CQL-to-RPN translation uses a configuration file, the name of
494 which must be specified in the Connection's "cqlfile" option.
496 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
497 function, which takes as its start-term parameter a ZOOM_query object
498 (which may have had either CQL or RPN set into it).
501 --- 2.1.10 2005/11/29
503 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
504 GFS to support this as well. Backend handler, bend_srw_update, does the
505 update work. Code contributed by Ko van der Sloot.
507 Allow retrieval of Search Result-1 information in ZOOM by the use of
508 options that are attached to a result set. ZOOM documentation updated
511 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
512 UTF-8 conversion. Patch by Raj Patel.
514 Added option -m to GFS to control formatting of timestamps in log file.
516 Added 'exit' as synonym for 'quit' in yaz-client
518 Added support for specifying SRW resultSetId + resultSetIdleTime in a
519 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
520 for the new members. Patch by Ko van der Sloot.
522 Added support for SRU POST. It is supported for content-type
523 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
525 Do not build the separate Multi-threaded (MT) library libyazthread.la.
526 Instead make the library libyaz.la multi-threaded. Threading as a whole
527 can still be disabled by configure option --disable-threads. Previosly,
528 with older GLIBCs there were problems with MT libs under Apache. This
529 has now been fixed a long time ago.
531 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
534 CQL module modified to be case insensitive for relations/indexes/operations.
536 Fixed bug in CQL transform code: incorrect value relationModifieder
539 Added 'show all' command for yaz-client which retrieves all results
542 Added new yaz-client, xmles, which takes a (private) OID and
543 a document to be sent as an extended service request.
545 Describe new yaz-client commands wait_response and set_auto_wait.
547 Increase TCP/IP listener backlog from 3 (which I am guessing was
548 copied from the SunOS manual entry way back when) so SOMAXCONN, so
549 that the socket will queue as many incoming connections as it's able
550 to handle ongoing connections. In other words, it will never now
551 refuse a connection that it would be able to handle merely because
552 it's not got around to accepting() enough of the pending connections
553 yet. This is the behaviour anyway under Linux, where the listen()
554 argument is ignored; but not under BSD and on systems such as
555 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
556 YAZ-based servers should now be uniform across operating systems in
559 yaz-marcdump uses 64-bit file access on some systems. This is enabled
560 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
561 This allows yaz-marcdump to read large MARC batches (>2 GB).
563 Modified all YAZ source files - except the source which is auto-generated
564 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
567 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
568 corresponding to the existing *_setl() function. These allow option
569 values containing arbitrary valuues.
571 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
572 ZOOM_resultset_sort() in new applications. Its behaviour is identical
573 except that it returns an indicator of whether or not the sort
574 criterion was accepted (0 for OK, -1 for invalid).
578 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
579 MARC output rather than returning "new" buffer.
581 yaz-client warns about unknown init options.
583 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
587 Added support for SRW sort in Generic Frontend Server. Patch
588 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
589 sortKeys - or NULL if none is provided.
591 Fixed bug #307: It was impossible to specify indefinite/no timeout
592 for ZOOM_event. Special timeout value -1 now means indefinite timeout
595 Added support for multiple languages and charsets to be specified in
596 ZOOM. Each charset/language is separated by a blank. If negotiation is
597 in effect in init-response, Option
598 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
599 Code based on patch by Vasiliy Osadchuk.
601 Fixed bug #306: infinite recursion that occurred when calling
602 yaz_log_level_init as the first call (before other log level or
605 Fixed bug in scan handling in front end server: if preferred-Position-In-
606 Response was non-present, a NULL pointer referece was performed.
610 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
611 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
612 now defined for all those error codes. So instead of putting 109 in
613 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
614 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
616 Modified the yaz-marcdump utility to skip garbage bytes between MARC
619 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
621 Program yaz-client now exits and produces an error message if multiple
622 Z39.50 servers are specified on the command line (none or one allowed
625 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
630 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
632 Fixed bug #272: Preserve spacing for CCL terms.
636 Added support for virtual hosts and multiple backend servers for
637 the YAZ frontend server. The configution is XML based and
638 support specificition of CQL to RPN mappings and explain information.
639 See section "Virtual Hosts" in the YAZ manual.
641 Extended OPAC display utility. OPAC display utility renders
642 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
643 to supplement yaz_marc_decode_wrbuf.
645 Fixed a bug in MARC decoder that could caused it to crash for some
646 invalid MARC records. More diagnostics and warnings where added in
647 XML output (warnings, etc are stored in comments).
649 --- 2.0.34 2005/02/08
651 Fixes for UNIX domain sockets. Bug #261.
653 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
655 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
656 Added yaz_marc_subfield_str which defines subfield lead string which is
657 used in YAZ_MARC_LINE format. Default string is blank+$. Added
658 yaz_marc_endline_str which defines end of fields string used in
659 YAZ_MARC_LINE format. Default string is newline.
661 Experimental support for MarcXChange. This format can be produced
662 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
663 http://www.bs.dk/standards/MarcXchange.xsd
665 Added yaz-client commands scansize that sets maximum number of
666 entries to be returned by scan.
668 --- 2.0.32 2005/01/11
670 Added support for SRW scan in yaz-client and Generic Frontend Server.
672 * Added whereInList member to SRW Scan Term.
674 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
676 Fixed NMEM system to return aligned blocks on the smallest boundaries
677 that are suitably aligned for all possible types on the particular
678 architecture YAZ is being built for.
680 --- 2.0.30 2005/01/04
682 Fixed numerious warnings that was issued with newer versions of GCC.
684 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
685 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
688 Make YAZ Generic Frontend Server slightly faster.
690 Enhance (and reduce) logging for Generic Frontend Server.
692 Revert YAZ log system so that it flushes every write operation
693 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
695 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
696 instead of LOG_, due to name clash with syslog(3). LOG_ are still
697 present. New applications should define YAZ_USE_NEW_LOG=1 - this
698 will effectively disable old definitions.
700 --- 2.0.28 2004/11/09
702 Added yaz_log_time_format which specifies log format using
705 Added yaz_log_module_level which returns mask for a module. Value
706 is non-zero mask a if module is enabled; zero if disabled.
708 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
709 in include/yaz/cql.h.
711 Fixed bug #176: Dont throw diagnostics on empty SRU args.
713 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
715 Fixed bug #172: RPM builds does not enable SSL.
717 Doxyfile.in part of dist. Doxyfile generated by configure.
719 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
720 are given and the corresponding component does not exist.
722 Extend CCL documentation in YAZ reference. Describe r=r.
724 --- 2.0.26 2004/10/01
726 Fixed MARC->MARCXML conversion to properly deal with
727 fields, subfields, indicators having non-ASCII characters.
729 Fixed MARC->MARCXML conversion so that ASCII control characters
730 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
733 Added YAZ GFS support for conversion from Z39.50 surrogate
734 diagnostics to SRW surrogate diagnostics.
736 Bug fix: YAZ GFS did not return schema in explainResponse.
738 --- 2.0.25 2004/09/30
740 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
741 now converts recordSchema to elementSetName as well as schema URI.
743 Fixed bug in COMSTACK that prevented HTTP request packages from being
746 --- 2.0.24 2004/09/29
748 Added CCL facility r=r "range" which is similar to r=o "ordered" but
749 does not require white-space before and after the dash in a range, e.g.
750 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
753 Fixed a few AC_TRY_LINK configure tests that did not operate properly
754 due to new GCC removing "redundant" code.
756 Added yaz-client commands scanpos and scanstep that sets preferred
757 position and step-size for scan.
759 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
761 Added CCL utility ccl_qual_buf which parses one or more CCL
762 spec lines in a buffer.
764 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
765 of name and value - ignoring empty lines and comments.
767 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
769 Added odr_get_element_path which returns current element path for an
770 ODR handle. This utility is useful in error handling or user-defined
773 Added ODR_PRINT utility odr_set_stream which is is a more generic
774 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
775 to a write function and pointer to close function. The close function - if
776 non-NULL - will be called during odr_destroy.
778 Fixed bug in CCL parser where truncation char was not removed from
779 right side when truncation=both was in effect.
781 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
784 --- 2.0.23 2004/08/11
786 Fix buffer overrun in CQL parser when dealing with proximity (%).
788 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
789 to UTF-8/UCS conversion is now only based on codetables.xml.
791 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
793 --- 2.0.22 2004/08/06
795 Add support for more "commit changes" in ZOOM (uses Extended Services).
797 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
800 Yet another small fix for configure of SSL.
802 --- 2.0.21 2004/05/14
804 Fix SSL libs for configure when --with-openssl=DIR is given.
806 --- 2.0.20 2004/05/10
808 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
810 SSL comstack now uses yaz.pem certificate file on server side
811 by default. Certificate filename can be configured by calling
812 comstack function cs_set_ssl_certificate_file before cs_bind is used.
814 Fix bug regarding multiple calls to ZOOM_connection_connect.
816 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
818 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
819 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
821 ZOOM now allows inspection of X509 peer certificate for verification.
822 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
824 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
825 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
826 as "modular" but it simplifies things.
828 Added cs_get_peer_certificate to that returns peer X509 PEM.
830 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
831 NULL if SSL is unavailable.
833 Documentation about MARC decoding tools.
835 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
837 --- 2.0.19 2004/03/30
839 Rename CHANGELOG to NEWS to follow GNU style packing.
841 Fix bug with missing initialization of member in init_diagnostics.
842 This bug affects threaded version of GFS server.
844 --- 2.0.18 2004/03/20
846 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
849 Ensure zlib.dll is packed with Windows install.
851 --- 2.0.17 2004/03/17
853 Fix encoding of xsd:string to use text instead of CDATA.
855 Fix endless loop in CQL parser with unbalanced ".
857 Use a more compact way to store MARC-8 conversion tables.
859 --- 2.0.16 2004/03/16 Debian only
861 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
864 Update CQL parser to use new CQL 1.1 modifiers for booleans and
869 --- 2.0.15 2004/03/01
871 Another fix for decoding of XML packed records.
873 --- 2.0.14 2004/02/25
875 Fixes for Chunked encoding. White space not ignored after length spec.
877 Update NS and use default NS for SRW diagnostic elements.
879 --- 2.0.13 2004/02/23
881 Implement ZOOM_resultset_cache_reset which resets record cache.
883 Implement ZOOM_resultset_sort which sorts a result set.
885 Implement chunked HTTP transfer.
887 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
889 --- 2.0.12 2004/02/16
891 Added member 'schema' to bend_explain_rr structure so that backend
892 can specify explain record identifier. Defaults to Zeerex 2.0.
894 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
896 --- 2.0.11 2004/02/16
898 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
901 Added init command for yaz-client which sends "extra" init request.
903 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
904 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
906 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
908 Make ZOOM error code for "invalid query".
910 Fixed compilation for SSL which wasn't properly enabled for all platforms.
912 --- 2.0.10 2004/02/05
914 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
917 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
919 Added option -p <file> to make Generic Frontend Server to write PID file.
921 Added option -D to put Generic Frontend Server in background on its own.
923 Make ZOOM C recognize option "password". If unset, "pass" is used
924 (for backwards compatibility).
926 Fixed a bug in Generic Frontend Server that could make it crash if a
927 client sets characterSetNegotation bit, but didn't pass negotiation stuff
930 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
931 Must be issued before open, in order to be in effect.
933 --- 2.0.9-6 2004/01/12 Debian/Windows
935 Make the SRU server more picky WRT unknown params, etc.
937 Bug fix: ZOOM scan response didn't return displayTerm - when present.
939 New YAZ client command, options, that sets Z39.50 options.
941 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
942 options from a string of tokens (one token for each option bit).
944 Update SRW diagnostic code messages.
946 --- 2.0.9-5 2004/01/07 Debian/Windows
948 Handle user defined stylesheet for SRW/SRU.
950 --- 2.0.9-4 2004/01/06 Debian/Windows
952 Fix bug in decoding of Content-Length.
954 --- 2.0.9-3 2004/01/06 Debian/Windows
956 Fix a bug with decoding of XML packed records.
958 --- 2.0.9-2 2004/01/05 Debian only
960 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
962 Fix bug in SRW/SRU diagnostics decoding.
966 Fixed bug in Generic Frontend Server which could drop records exceeding
967 preferred message size. Reported and fixed by Irina Dijour.
969 Fixed calculation of package size for structured records in Generic
970 Frontend Server. Reported and fixed by Irina Dijour.
972 Fixed namespace for SRW/SRU diagnostics.
974 Fixed SEGV in yaz-client that occured for HTTP connection errors.
978 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
979 this version is incompatible with version 1.0 and older YAZ SRW/SRU
982 CQL changes to reflect recent changes to the specification:
983 * Documentation talks about context sets instead of index sets.
984 * Documentation talks about indexes instead of qualifiers.
985 * The CQL-to-PQF transformer's configuration file now uses
986 "index.set.name = <attributes>" instead of the old form
987 "qualifier.set.name = <attributes>". (Both forms are still
988 understood but the latter is deprecated.)
989 * CQL terms with no explicit index specified are now interpreted as
990 cql.serverChoice instead of srw.serverChoice (which of course
991 behaves exactly the same.)
995 MARC conversion can now generate ISO2709 output in another
996 character set. yaz-marcdump uses this facility if you invoke it
999 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1000 functions from there can be used from C++.
1002 --- 2.0.6 2003/12/04
1004 Frontend server now transfers memory from decoded packages to stream
1007 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1008 references to show up.
1010 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1011 the ZOOM Abstract API. The older names for the same options are still
1012 also supported for the benefit of old applications.
1014 ZOOM-C supports "implementationId" and "implementationVersion" options
1015 to go along with "implementationName". These allow the user code to
1016 specify identification strings to be sent to servers.
1017 Add OID for the new ExtLite attribute set.
1019 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1020 as requested/supplid by Ere Maijala <ere@atp.fi>
1022 For generic frontend server, reverse the order of
1023 "toolkit-supplied / application-supplied" strings sent as implementationId,
1024 Name and Version. Also, remove the spaces around the slash. This brings
1025 the GFS in line with the behaviour of ZOOM-C on the client side.
1027 Add function ZOOM_scanset_display_term.
1029 yaz-client shows scan displayTerm if present.
1031 Utility yaz-iconv is now installed by default along with the man page
1034 Extend configure check for OpenSSL to use pkg-config where available (such
1037 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1038 server to specify uid/gid/mask for socket using the format
1039 unix:[user=uid,][group=gid,][umask=mask,]file=path
1040 If file= is omitted the existing format is assumed, e.g.
1042 in which case the mask is 0666 (rw for everybody).
1044 Major restructure of YAZ source. All source in libyaz is in src directory.
1045 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1046 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1048 Added man page for utility yaz-marcdump (used to be called marcdump).
1049 yaz-marcdump is installed by 'make install'.
1051 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1052 of incoming package failed.
1054 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1056 Change prototype of odr_perror: add const to message string.
1058 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1060 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1061 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1062 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1063 DNS lookup. There should not be any compatibility problems with this
1064 assuming that blocking=1 or 0 is used.
1066 Fix bad reference in UNIX comstack in function cs_addrstr.
1068 Fix for compilation on AIX.
1070 The generic front-end server (server/seshigh.c) now supports returning
1071 Init diagnostics to the client in User-information-field, in
1072 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1075 --- 2.0.4 2003/09/04
1077 Allow any CQL relation (not just all,any,exact,scr).
1079 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1080 that features the same UI.
1082 Implemented command update0 in YAZ client which is equivalent to
1083 update but uses old of Ext Update ASN.1.
1085 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1086 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1087 Previously no OID was used for this info.
1089 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1090 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1091 returns 'malformed search term' otherwise.
1093 SortResponse member resultCount now set to NULL in sort handler of
1096 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1099 Add three new utility functions for translating OIDs between various
1100 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1101 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1102 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1103 char *oid_to_dotstring(const int *oid, char *oidbuf);
1104 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1106 Reverted modifications for ES Update definition for z_IU0Update
1107 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1108 is back to YAZ 2.0.2.
1110 String value attributes for CCL parser.
1112 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1113 which their FirstSearch server returns in Init responses, sometimes
1114 carrying useful diagnostic information when Init fails. This has the
1115 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1116 "z39.50/oclcui.asn", where its definition is somewhat different from
1117 what OCLC document on their web-site, as required to interoperate with
1120 Support for anonymous authentication in yaz-client. Use the command
1123 * Fix the OID of the Index Data-local "admin" Extended Service from
1124 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1125 the 1000, which indicates a locally-defined OID, was a mistake.
1127 --- 2.0.3 2003/06/20
1129 Fix CCL directive @case handling so that it affects string match for
1130 both CCL keywords and qualifiers.
1132 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1133 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1134 Decoder has been updated with ASN.1 changes as listed in
1135 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1136 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1137 z_IUUpdate, remains unchanged.
1139 ZOOM_record_get may now return a record in a specific character set.
1140 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1141 "from" is the character set of record as returned by target. "to" is
1142 the character set to be returned. If omitted, "to" is UTF-8.
1144 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1146 New ODR utility, odr_getelement, which returns name of element for
1147 which encoding/decoding failed.
1149 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1150 in cases where a required element was omitted.
1152 Bug fix: some MARC8 sequences were not converted.
1154 New ZOOM option "step" which specifies number of records to be
1155 retrieved in one chunk. Used in conjunction with "start" and "count".
1157 SRW support for yaz-client. Use scheme http: to use it, e.g.
1160 yaz-client no longer does (un)intelligent character set conversions
1161 by default. Can be enabled with charset and marc_charset commands.
1163 xmalloc trace fix for 64-bit systems such as DEC alpha.
1165 Solaris 2.6 compile fix.
1167 New function, cql_strerror() translates SRW error codes, as returned
1168 by cql_transform_error(), into human-readable English strings. Used
1169 in yaz-client diagnostics when appropriate.
1171 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1172 converts it into a type-1 query which is sent to the server. This
1173 makes CQL available for use with all Z-servers, as opposed to the tiny
1174 minority that can handle CQL queries themselves.
1176 --- 2.0.2 2003/04/28
1178 New Debian package layout similar to the Redhat Package layout.
1180 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1181 and search result respectively.
1183 --- 2.0.1 2003/04/25
1185 Redhat package is now several packages: libyaz (runtime libraries),
1186 libyaz-devel (development and documentation, and yaz (utility programs).
1187 Package spec file by Morten Bøgeskov.
1189 New member 'schema' in struct bend_fetch_rr which the name of requested
1190 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1191 handler MAY set this to reflect the schema of the returned record.
1193 New member 'display_term' in struct scan_entry. GFS now sets member entries
1194 and allocates scan entries to be filled by user scan handler. In previous
1195 version, entries member was allocated by the scan handler. That still works,
1196 but the GFS will ignore member display_term - assuming it was NOT set by
1197 the handler. The fact that the GFS now allocates the entries both allows
1198 for new members and makes a scan handler easier to write.
1200 Fix CQL lex buffer overflow.
1202 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1203 SRU default recordPacking is string.
1205 SRU protocol support for frontend server.
1207 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1209 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1211 Added scan for the ZOOM shell (zoomsh).
1215 * String Identifers for Schemas (Amendment 5).
1216 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1217 Old definition for schema
1218 Odr_oid *schema; /* OPT */
1223 Z_InternationalString *uri;
1224 #define Z_Schema_oid 1
1225 #define Z_Schema_uri 2
1228 * resultCount parameter to Sort Response (Amendment 1).
1229 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1231 Support for SRW 1.0 over HTTP. This is an optional feature and
1232 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1235 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1236 on the same port. SRW SearchRetrieveRequests are mapped
1237 to bend_init,bend_search,bend_fetch,bend_close.
1239 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1241 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1242 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1244 ZOOM connections are SRW based if schem http is used for hostname
1245 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1246 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1248 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1249 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1250 distance=n, order=true/false, relation=le, prox unit=word. If
1251 n is omitted, distance 1 is used.
1253 Fixed problem with C compiler include path in wrong order.
1255 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1256 on Solaris. Patch from Ko van der Sloot.
1258 New MARC decode API. All new functions operate on a yaz_marc_t
1259 handle. The most important new functions are: yaz_marc_create,
1260 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1261 decode and destroy respectively. Decoder can produce formats
1262 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1263 include/yaz/marcdisp.h.
1265 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1266 to UTF-8, UCS-32, wchar_t or Latin-1.
1268 * Prototypes for yaz_iconv_-functions moved to separate header
1269 include/yaz/yaz-iconv.h.
1271 Make a few private functions 'static' in unix.c. This prevents
1272 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1274 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1275 are set when Init Response is received.
1277 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1278 but returns diagnostic set as well.
1280 New function yaz_strerror which is a portable wrapper for
1281 strerror/strerror_r/GetLastMessage.
1283 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1284 is returned for MARC. If type is "oai", then OAI MARC is returned.
1286 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1289 --- 1.9.2 2002/11/26
1291 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1293 Fix bad race conditions on SIGTERM and terminate gracefully in
1296 Move retrieval (data1) module to Zebra since nobody seems to be
1299 Add GRS-1 render for ZOOM using same format as yaz-client.
1301 --- 1.9.1 2002/10/05
1303 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1305 Fix broken ESpec handling in data1 module.
1307 SGML reader parses comments and makes them part of the data1 tree.
1309 Added several type casts so that YAZ compiles as C++ code.
1311 ZOOM didn't handle PDU encoding failures properly.
1313 Added more Bib-1 diagnostics (approved extensions).
1315 GNU configure: better check for iconv.
1317 More portable use of accept, getpeername. Check for socklen_t. Use
1318 int/size_t if socklen_t is not defined.
1322 PQF parser rejects bad queries - including those with extra
1323 characters in them. PQF parser used to silently ignore that.
1324 Cleaner API for PQF added, which allows you to get detailed
1325 error information for bad queries (see yaz/pquery.h).
1327 Fixed bug in ZOOM_record_get for type "database".
1329 Implemented mini iconv library supporting conversions between
1330 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1332 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1334 --- 1.8.9 2002/08/20
1336 Fixed ZOOM C record cache so that preferredRecordSyntax and
1337 elementSetName is used to check for already fetched records.
1339 --- 1.8.8 2002/08/02
1341 Added three members in bend_initrequest structure to facilitate
1342 character set negotiation.
1344 Fixed a bug in frontend server that could cause indefinite
1345 loops under rare conditions.
1347 Revised character set utilities (charneg.h) so that encoding
1348 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1350 For PQF, directive @term <type> sets term type for Scan/Search.
1351 Here <type> is general, string, numeric, null. The term type
1352 is inherited - just like @attr.
1354 New call odr_set_charset that sets character set conversion for
1355 international-strings on a ODR stream. Prototype is:
1356 int odr_set_charset(ODR o, const char *to, const char *from);
1357 The InternationalString is still represented as C string in YAZ
1358 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1359 won't). On the protocol level, you can use any encoding.
1361 Support for UNIX sockets in ZOOM.
1363 Solaris recv sometimes returns errno == ENOENT. It is treated as
1364 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1366 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1367 both client and server. Code by Morten Bøgeskov.
1369 --- 1.8.7 2002/05/22
1371 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1372 that they can be used directly from Visual Basic. You must recompile
1373 your windows APP if you're using ZOOM.
1375 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1376 Commands "lang" and "charset" sets language and character set respectively.
1377 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1378 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1380 Attributes from multiple CCL fields may be OR'ed rather than merged
1381 using directive "@field or". Fields are still merged by default -
1382 equivalent to "@field merge".
1384 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1387 Fixed bug in zget for parameter ExtendedServicesResponse.
1391 --- 1.8.6 2002/03/25
1393 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1395 Client displays USR.1:SearchResult-1 (hits per term).
1397 Additional Search Info for search in Generic Frontend Server.
1399 Fixed CCL parsing of "field=s".
1401 WIN32 installer - using the excellent NSIS software from nullsoft.
1403 Fixed CCL parsing of "field = - <number>".
1405 Added function yaz_marc_decode that decodes MARC for line mode
1406 display or XML (similar to that used by JZKit).
1408 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1409 Z39.50. But ISO/ILL was, however.
1411 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1412 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1414 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1415 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1417 --- 1.8.5 2002/02/03
1419 New YAZ client features: Command completion and new commands:
1420 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1421 Code provided by Jacob Poulsen.
1423 New call oid_trav, that visits all registered OIDs via callback.
1425 Function ZOOM_record_get now returns const char pointer rather than
1426 void pointer. It saves a lot of type casts.
1428 For YAZ client, command "auth" now allows you to set authentication
1429 in IdPass style. It is enabled when three tokens are given - order
1430 is user, group and password.
1432 Fix memory leaks in MARC record handling for ZOOM.
1434 New option for YAZ client, -k <kilobytes> that sets
1435 maximum record size. Similar to -k option for generic frontend
1436 server and yaz-ztest.
1438 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1440 Prefix query parser reports "fail" when bad attribute set is given.
1442 Fix in MARC decoder. Proximity logging. Fix for attribute set
1443 in scan handler for server. Patches by Shigeru Ishida.
1445 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1448 Configure option --with-openssl=<dir> now works when a directory is
1449 specified. Patch provided by Morten Bøgeskov.
1451 New option for YAZ client, -u <auth>, that sets authentication.
1453 ZOOM fix: error information was sometimes "missing", since error
1454 was cleared/reset too when it shouldn't.
1456 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1458 --- 1.8.4 2002/01/04
1460 Scan for ZOOM API. New object ZOOM_scanset. New functions
1461 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1462 ZOOM_scanset_destroy.
1464 New ZOOM function, ZOOM_connection_last_event, that returns type
1465 of last event (such as "receive data", "send data", "apdu received",
1468 New ZOOM option, schema, that specifies schema for retrieval.
1470 New CCL feature. Qualifiers can be aliases for one or more
1471 other qualifiers (if more than one is given, OR is used).
1473 ZOOM uses named result sets if target supports it.
1475 Two new YAZ client commands: . (dot, which sources a script of YAZ
1476 client commands), and ! (to execute shell command.). Implemented
1479 Working on Debian packages.
1481 --- 1.8.3 2001/11/19
1483 YAZ client enables named result sets only if target supports it.
1485 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1487 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1488 with key="host" to get same result.
1490 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1491 Function Z3950_resultset_record(s) returns references to records
1492 "owned" by resultset. To become owner use Z3950_record_clone.
1494 Function z_ext_record handles Extended Services. Thanks to
1497 --- 1.8.2 2001/11/12
1499 CCL Parser fix: ignore token comma when dealing with and-lists.
1501 Documentation updates for COMSTACK.
1503 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1504 Changed prototype Z3950_records. For some functions, int parameters
1505 were changed to size_t.
1507 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1510 New MARC decode/display function, marc_display_exl, which properly rejects
1511 non-ISO2709 records. YAZ client uses it.
1513 --- 1.8.1 2001/10/29
1515 Fix bug: local attribute set wasn't set correctly in PQF strings.
1519 * Old Z39.50 codecs no longer supported.
1521 Added ZOOM C binding. See http://zoom.z3950.org/
1523 Renamed states for COMSTACKs to avoid confusion with events.
1525 Implemented cs_look and proper cs_rcvconnect.
1527 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1529 Configure detects POSIX threads on OpenBSD.
1531 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1532 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1534 When error is returned from present handler, non-surrogate diagnostic
1535 is returned in present response (and fetch handler is no longer called).
1537 * Minor adjustments to pquery parser (PQF). Token characters may be
1538 escaped by using backslash (C-style).
1540 PQF parser allows string attribute values to be specified. For @attr,
1541 non-numeric characters after the equal-sign are treated as strings
1542 (e.g. @attr 9=title).
1544 CCL trunction character may be defined (@truncation in file)
1546 * function zget_ExtendedServicesRequest sets waitAction to
1547 waitIfPossible (was wait).
1549 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1552 CCL operator names may be set in field definition files (CCL_bibset).
1553 See ccl/bib1 for an example.
1555 Fixes in ASN.1 compiler for C++ compatibility.
1557 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1558 and "op_or" to avoid conflict with C++.
1560 Fixed problem with GNU readline detection on Redhat 7.0.
1562 Added step-size for Scan backend handler.
1564 Fixed bug that made the frontend server crash when no attribute
1565 set was specified for scan.
1567 Front-end server automatically switches to original working directory
1568 when installed as an NT service. Previously -w had to be specified to
1571 Added extended attributes for retrieval module (data1), so that data1
1572 records carry d1_readXML/SGML attributes. d1_read also supports
1573 null-data rules ( <tag/>)
1575 On UNIX when POSIX threads are available, a separate library libyazthread
1576 is created. Programmers should link with that library and the yaz library
1577 when using threads. The reason for the split was that some applications
1578 on Linux, such as Apache, doesn't work well when using shared objects that
1581 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1582 (or any frontend server) in SSL mode by specifying ssl: followed by
1583 address. Only tested on UNIX.
1585 Added feature for CCL module. Virtual structure s=al or s=ol generates
1586 and-list and or-list respectively instead of phrase search.
1590 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1591 log_mask_str. This was done to avoid name conflicts with other libraries
1592 (such as other PHP extensions).
1594 Added raw OID member for preferred record syntax (request_format_raw)
1595 and returned record syntax (output_format_raw) for backend fetch method.
1597 Config file yaz-config now accepts options so that it returns specific
1598 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1600 Shared library support for UNIX using GNU libtool.
1602 * Modified backend interface. Request/Response struct's replaced by
1603 one read/write C struct. For example bend_fetchrequest and
1604 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1605 Every handler - even search has to be registered in bend_init
1606 handler. This means that the YAZ library no longer refers to
1607 external functions and it makes it possible to make the whole
1608 thing a single DLL/SO.
1610 Added Segment handler for backend server.
1612 Added Zmbol/Zebra administrative functions to YAZ client.
1614 Threaded frontend server on UNIX (when POSIX Threads are available).
1615 Starting the server with option -T enables multi-threading.
1619 Added configure option --enable-comp/disable-comp to control use
1620 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1621 located in sub directory asn.
1623 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1624 in ${exec_prefix}/bin along with the other programs yaz-client and
1627 GNU automake used to maintain makefiles.
1629 Added several OID's.
1631 Changed retrieval module so that we can load records with no abstract
1632 syntax defined. Tagpaths in these records are fully composed of string
1635 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1639 On UNIX, the generated makefile now supports a proper 'make install'.
1640 The prefix can be set via GNU configure to set the install location
1641 (default is /usr/local).
1643 * YAZ programs client and ztest were renamed to yaz-client and
1644 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1645 locations, such as /usr/bin,/usr/local/bin,etc.
1647 * YAZ Header files were moved from include to include/yaz. YAZ Header
1648 files are referred to as include <yaz/log.h> rather than <log.h>.
1649 The YAZ include path (-I ..) is therefore the same as before. Programmers
1650 should update their #include statements or use -Ipath/include/yaz
1651 instead. The main motivation for doing this change is that YAZ header files
1652 can be installed in "standard" locations /usr/include,/usr/local/include
1653 without introducing conflicts, since ALL YAZ header files are stored
1654 in subdirectory yaz (under /usr/include for example).
1656 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1657 rather than project/workspace files. We switched because project files
1658 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1661 Changed name of logging function, logf, to yaz_log, to prevent name
1662 clash with some math-log functions. The YAZ header log.h defines logf
1663 to yaz_log (#define) so there should be no incompatibilities by this
1666 Added bend_start/bend_stop handlers for server. These handler are
1667 called on start/stop of server. For windows they are called whenever
1668 a service is started/stopped.
1670 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1671 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1672 in util/yc.tcl. The auto-generated C code structures are, in a few
1673 cases, incompatible with the old decoders. There are differences in the
1674 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1675 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1676 The preprocessor variable ASN_COMPILED is defined when the compiled
1677 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1678 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1679 wish to use the old encoders/decoders you can specify --disable-yc
1682 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1683 version so that it supports both new - and old version of DB Update
1685 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1686 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1687 change. The name parameter can be set to 0 in which no name is specified
1688 for the construction. The macros odr_implicit and odr_explicit sets name
1689 parameter to zero for the construction involved. New macros
1690 odr_implicit_tag and odr_explicit_tag are similar to the others,
1691 except that a name parameter is added. For programmers' that don't use
1692 ODR they probably only need to change the call to z_APDU and z_External.
1694 Added access control facility by interfacing the TCP wrapper library.
1695 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1696 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1697 name of the daemon and enables the access control as specified in
1698 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1700 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1701 den Dool <H.M.vdnDool@kub.nl>.
1703 Added reference ID parameter to most functions in server API - refer
1704 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1706 Changed name of ccl library to libccl.a (was ccl.a).
1708 Fixed bug in decoder for Explain (Category TargetInfo).
1710 Added support for GNU readline in client. Thanks to Jacob Poulsen
1711 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1713 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1714 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1715 IMPLEMENTATION! This change was made to the development version before
1716 the ZIG decided to retract the amendment. If any users MUST be
1717 compatible with the original Update definition, PLEASE CONTACT US, and
1718 we will include a separate definition corresponding to the old Update
1719 ES. Note that because of the change to the ASN.1 of the
1720 TaskPackageRecordStructure we cannot define a single structure that
1721 will support both versions.
1723 * Added const modifier to buffer parameter for some ODR/BER encoding
1724 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1725 completeWAIS, odr_dumpBER.
1727 Fixed bug in client.c which caused a crash when a scanResponse didn't
1728 contain positionOfTerm.
1730 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1731 * will cause an error in a client if a non-YAZ target sends both a
1732 * list of Scan entries and non-surrogate diagnostics.
1734 Retrieval module enhancements. Tag sets may be typed in the reference
1735 to it. From the .abs-file the "tagset" directive takes a third optional
1736 integer type for the tag set referenced. From a .tag-file the "include"
1737 directive takes a third optional type as well. The old "type" directive
1738 in the tag set itself is still recognized but acts as the default type
1741 Backend interface change. Individual Scan terms returned from bend_scan
1742 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1743 in include/backend.h.
1745 Retrieval module enhancements. Multiple tag sets and attribute sets may
1746 be specified in abstract syntax specs. Revised the error/warning for
1747 logging messages reported by the retrieval module when reading the
1750 Object Identifier system (oid_..) changed. The API is backwards
1751 compatible but the oid-routines now allocates new OID's when needed.
1752 Raw OID's may be specified in oid_getvalbyname.
1754 YAZ now uses GNU configure to generate Makefile(s).
1756 * Minor changes in some of the member names of DeleteResultSetRequest and
1757 DeleteResultSetResponse. See include/proto.h.
1759 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1760 and added member 'languages' in TargetInfo (which was missing).
1762 Changed the way attribute sets are handled in the retrieval
1763 module. These are now cached, just like the abstract syntaxes
1766 Changed YAZ so that it links with compiled ASN.1.
1768 Added Explain-schema definitions and mapping routines. The following
1769 Explain categories have been implemented: AttributeDetails,
1770 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1772 Fixed minor bug in Windows version of Server Library.
1774 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1776 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1778 Added EXTERNAL: UNIverse Resource Report (non-standard).
1780 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1781 ENUMERATED and SET OF.
1783 * Added 'const' to some of the char pointer arguments for the
1784 functions, data1_read_node, data1_getelementbytagname,
1785 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1788 Fixed bug in data1_insert_taggeddata - the last_child member of
1789 parent wasn't initialised.
1791 * Changed data1_read_record and data1_read_node so that the supplied
1792 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1793 doesn't refer to any parts of the "SGML"-buffer.
1795 Fixed bug in server library (Windows version of statserv_remove).
1797 * Changed code so that it compiles as C++. The type definition
1798 of Odr_fun which is a member of Odr_arm was changed. The result is,
1799 that an explicit typecast is needed for the fun pointer when
1800 using Odr_arm - as in:
1801 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1803 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1805 Implemented the new structured date and time definition as approved
1806 by the ZIG. Added schemaId element to the specificTag in Espec-1
1807 (also approved at the last ZIG). Thanks to RVDM.
1809 Added some Object identifiers (RVDM).
1811 Changed the Update Extended Service (RVDM).
1813 Added command "refid" to client which specifies referenceId for
1814 the following requests.
1816 Implemented extended service handling for server. See ztest.c
1817 for an example as well as backend.h. New handlers are registerd
1818 in the Init handler.
1820 * Changed interface for sort in server.
1822 Added new members to statserv_options_block. It allows a server
1823 to read options from another source than just the command line. Thanks
1824 to Charles Woodfield.
1826 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1827 renamed to zboolean. Some C++ compilers complained about the name.
1829 Minor changes to gils.abs. Added index 's' (sort) on title
1830 and date/time-last-modified.
1832 --- 1.4pl2 1998/1/30
1834 Fixed bug in server library regarding inetd mode (-i). This bug
1835 was introduced by release 1.4.
1837 --- 1.4pl1 1998/1/29
1839 Added sort facility in client and backend server interface.
1841 Fixed problem with dependencies in Makefile(s).
1843 Fixed bugs for encoders/decoders of extended services and
1846 Implemented sub-tree feature for schemas. Sub-trees are
1847 referenced in *.abs-files. See explain.abs for an example
1848 of the use of this feature.
1850 Modified bib1.att; local attributes for ANY didn't include
1851 ANY itself (only affects use of the retrieval module).
1853 Fixed bug in plain SGML reader in function data1_read_node:
1854 tags with prefix "var" was incorrectly interpreted as variants.
1856 Added feature "sub-schemas" to enable references to - and definitions
1857 of - group of elements.
1859 * Removed member parent from type data1_element (in data1.h).
1861 Implemented function odr_nullval() that returns the value of
1864 * Removed member num_children from data1_node (in data1.h).
1866 Made NT service interface part of the server library. The
1867 function statserv_main uses the NT service when required and
1868 calls the statserv_start / statserv_close routines.
1870 Routine zget_SearchRequest and zget_PresentRequest fills
1871 resultSetName/Id member with "default" instead of "Default".
1873 Fixed memory leak in server. Request queue member wasn't freed.
1875 Fixed nmem_exit so that memory is freed.
1879 Revised the CCL parser utility to be thread safe.
1881 Added function, oid_ent_to_oid, to replace the function
1882 oid_getoidbyent, which is not thread safe.
1884 * Added nmem_init and nmem_exit to initialize and release
1885 NMEM resources. Function nmem_init should be called once in the
1886 initial thread before NMEM/ODR is used. statserv.c and client.c
1887 have been changed accordingly. The change was necessary to make
1888 NMEM thread safe. The NMEM memory pool is shared amongst threads
1889 in a process. Unix-based applications will still work fine without
1892 Added NT Services interface for the the Z39.50 (statserv) Server.
1893 Refer to the ztest.c source on the usage.
1895 Windows 95/NT port using MSVC5.0. Project files are included in the
1898 * Defined new 'global' handle for the retrieval (data1) system. The
1899 new handled, data1_handle, describes the state of the data1 system.
1900 This handle is passed as first argument to virtually all
1901 data1 related routines. The functions data1_create and data1_destroy
1902 creates and destroys a data1 handle respectively.
1904 Added ODR encode stream member to all backend request structures
1905 init, search, scan etc. This stream should be used to allocate all
1906 memory used for the response when thread safe operation is needed.
1908 Changed the comstack utility, cs_addstr, to be thread safe. The
1909 returned hostname string returned by the function is now part the
1912 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1913 function. The cs_straddr takes a COMSTACK handle as argument, so this
1914 function must be used after cs_create and before bind/connect.
1915 This function is thread safe.
1917 Moved test server to 'ztest' directory - generic server code still
1918 in 'server' directory.
1920 Made prefix query (pquery.c) utility thread safe.
1922 Added new function modifier YAZ_EXPORT to 'export' public DLL
1923 functions when using windows (see include/yconfig.h).
1925 Added definitions to the OID database (util/oid.c) (RVDM).
1927 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1929 Added call to ccl_rpn_delete in client program.
1931 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1932 release of RPN structure.
1934 Added support for C++, headers uses extern "C" for public definitions.
1935 With input from RVDM.
1937 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1938 Thanks to Ronald van der Meer (RVDM).
1940 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1942 Added support for private extensions to the OID database
1943 (oid_setprivateoids()). Thanks to RVDM.
1945 Added optional, physical ANY (key replication)
1947 Fixed null-reference problem in GRS-1 output filter.
1949 Proximity operator added to Prefix Query Format (PQF).
1951 In test client command "base" accepts multiple databases.
1953 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1957 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1959 Smallish bug-fixes in the new encoders/decoders (explain).
1961 Bug fixed in DeleteRequest.
1963 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1965 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1967 Added SOIF syntax (using private OID for now) to retrieval module and client.
1969 Added Update extended service.
1971 Added SearchResult-1 additional info structure.
1973 Added optional CCL (ISO8777) interpreter as separate module. Available
1976 --- 1.2 1996/6/10 (1st anniversary release)
1978 Added Summary record syntax. Lightly tested.
1980 Added OPAC record syntax. Untested.
1982 Added ResourceReport service encoders/decoders. Untested.
1984 Fixed bug in z_Unit - wrong tagging on unitSystem.
1986 Fixed bug in the DiagRecs decoder.
1988 Added options for max PDU size and session timeout to frontend-server.
1990 Added documentation of query-language parsers and other supporting utilities.
1992 [frontend-server] Added Attribute set to the bend_scanrequest API.
1994 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1995 surrogate diagnostics were generated.
1997 [retrieval] Allow multiple local values for attribute.
1999 [retrieval] Allow multiple attributes per element in .abs files. index type.
2001 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2003 --- 1.1pl2 1996/4/10
2005 Minor changes, mostly specific to Zebra's requirements (retrieval)
2009 Repaired bug in frontend server when running multiple listening
2010 endpoints in dynamic mode.
2012 z_External() now won't break if a known, ASN.1 value comes encapsulated
2013 in an octet-string. The value will pass through unmodified in an Odr_oct.
2015 Added a bit of code to the demo client to decode & display
2016 ASN.1-structured records represented in the octet-aligned branch of
2017 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2019 Added z_ext_getentbyref() to the ASN module. Doc updated.
2021 * Completed the SCAN definition in the ASN module. This may break SCAN
2022 code based on older YAZ-versions at compile-time. The fix is easy -
2025 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2026 under the SCAN definition. Remember to initialize this, server-people.
2028 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2029 that this does not extend to ODR and ASN.
2031 Comstack allows insertion of established socket (primarily for
2032 inetd-operation of servers). Doc updated.
2034 Front-end server can now start from the inetd in TCP mode. Doc
2037 --- 1.0pl4 1996/1/24
2041 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2042 the rank and record number.
2044 Adjustments to the frontend server.
2046 Fixed diagnostic BER dumper. It ignored the file argument.
2050 Various changes to retrieval module.
2052 Changed the union discriminators of the protocol files from enums to
2053 ints paired with #defines.
2055 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2058 *Changed operator in the RPN structure to 'roperator', again to avoid a
2061 Fixed problems in Explain decoders/encoders.
2063 --- 1.0pl2 1995/12/6
2065 Memory bug in log module fixed.
2067 --- 1.0pl1 1995/12/5
2069 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2071 Bug in Explain DatabaseInfo module fixed.
2073 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2077 The shift to v1.0 signals that we now consider the *core* functionality
2078 of YAZ reasonably stable (the core being more or less equivalent to
2079 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2080 tested (Explain not at all - though that will happen soonish).
2082 Minor changes to code to support Windows port.
2084 Various minor changes after we're getting to use GRS-1 & co. more.
2086 Added Espec-1 format.
2088 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2089 of the protocol and it cannot be selected when encoding (maps into 'string'
2090 when decoding). Needed to talk to some servers.
2092 Demo client can request simple element set names.
2094 Added Diagnostic Format encoders/decoders.
2096 Added simple Close handling to frontend server (no hooks for resource
2097 reporting yet), and demonstration client.
2099 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2101 --- 1.0b3 1995/08/24
2103 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2104 handled incorrectly when records were requested in the searchResponse. This
2105 will only affect you if you use the frontend-server.
2107 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2108 Test-client will ask for and print GRS1. Ztest will return dummy records
2111 Added Explain encoders/decoders to the service-level API. Untested.
2113 Added Extended Services: Item Order encoders and decoders to the Service-
2114 level API. Untested. We could use a recent copy of the pertinent bits
2115 of the ILL protocol to add those bits.
2117 Added diagnostic format 1 encoders/decoders to the service-level API.
2120 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2121 odr_cons.c, which causes a more correct output.
2123 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2124 was always set to 0 when no records were requested in the searchRequest.
2126 * Added better external-handling. This shouldn't harm old code that
2127 *encodes* externals. It can break code that looks for a
2128 'single-ASN1-type' representation, since those types that are known
2129 are now decoded immediately. Look at the SUTRS sample code in
2130 seshigh.c and client.c. Documentation updated.
2132 Handling of structured records in bend_fetchresponse. Length -1 marks
2133 structured record, type is deduced from format field.
2135 --- 1.0b2 1995/06/27
2136 Fairly quick maintenance release to add SUTRS support.
2138 Fixed handling of SUTRS records in the demonstration client.
2140 * Added format field to the bend_fetchrequest and bend_fetchresponce
2141 structures of the backend API (frontend server). When the record is
2142 returned, the value of the format field is mapped to an OID. The
2143 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2144 of the record. The special value VAL_NONE in the bend_request means
2145 that no specific format was requested by the client. Documentation
2146 updated accordingly. Test server (ztest) will return a fixed dummy
2147 SUTRS record if your client requests SUTRS.
2149 Documentation updated accordingly.
2151 You can now set external libraries and RANLIB support in the top-level
2155 First public release.
