3 Changes to generic frontend server interface: added new member
4 'query_charset' for bend_initrequest structure. A backend init handler
5 should set this member to its native character set for query terms.
6 When defined, the frontend server logic will announce this character set
7 to a client if the negotiationModel bit is set by the client. All server
8 implementors are encouraged to specify this. If a backend server does not
9 specify this a warning is issued using yaz_log(YLOG_WARN,..).
11 Added CCL utility to remove terms (stop words) from resulting RPN
12 tree. This is handled by functions with prefix ccl_stop_words_ .
14 New ZOOM C option, "rpnCharset", which allows client-side conversion of
17 Clean-up the CCL API. Moved some internal structures from ccl.h to
18 private header cclp.h. Changed ccl_parser_create so that a Bibset must
19 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
20 This is replaced by ccl_parser_find_str which takes a string instead.
22 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
23 libyaz.la is the core of YAZ except the generic frontend server and
24 does not depend on POSIX threads anymore. libyaz_server.la is the
25 generic frontend server facilities and uses POSIX thread functionality
26 if available. The libyaz.la no longer depends on POSIX threads because
27 the number of global structures is limited. NMEM no longer re-uses blocks
28 between threads ; it simply free's memory immediately but allocates in
29 "large" chunks as usual. We don't expect any performance penalties
30 because of this. The yaz_log system is still using a global log_level so
31 caution must be taken when modifying it with yaz_log_init_.. +
32 yaz_log_mask_str. This, however, should not cause any trouble because
33 these functions are called during initialization of application code
34 anyway. `yaz-config --libs server` returns libs for server applications;
35 `yaz-config --libs` returns libs for non-server applications.
37 New OID database - with public definitions in oid_db.h. Removed old OID
38 database including the head oid.h and definitions such as enum oid_value
39 and struct oident. The new OID database uses the same string names as
40 before but the 'protocol' is gone. There are now only two representations
41 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
42 converts from string to OID; functions with prefix yaz_oid_to_string
43 converts the other way.
45 Change to emit_term() in CQL-to-PQF query translation: when a term has
46 the /regexp relation modifier, do not process it for leading and
47 trailing "^" and "*", which have quite different meanings in regular
50 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
51 write handlers no longer carries a 'last' parameter. This will make
52 yaz_iconv flush "less" characters. A flush is performed by call to
53 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
55 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
56 removed, because function yaz_query_to_wrbuf does the same.
58 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
59 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
61 Deprecated MARC utility functions removed.
63 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
66 Branch split: YAZ_2_1_55_branch
70 Fix to ZOOM-C so that transparent reconnection is properly handled on
71 connections that are in asynchronous mode.
73 Fixed compilation on OpenBSD 4.0.
75 Large strings in GRS-1 records are now properly displayed in yaz-client.
77 Added character conversion support for "advancegreek"; based on patch from
80 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
81 sequence is met. Before the error was not set so it would be unknown.
83 Adjust yaz-marcdump MARC reader so that it skips until record separator
88 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
89 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
90 fd_set structure used as a bitmask for the FDs to be selected on.
92 Using ACX_PTHREAD macro to check for POSIX threads.
94 Fixed have-vsnprintf check.
98 Fixes for configure on BSD. Bug #900.
100 Added snprintf/vsnprintf wrappers for systems that don't have
101 limits (heavens forbid).
103 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
104 created before all previous tasks were completed and removed from the
105 task queue, the new task could be removed by a mistake.
107 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
109 Implemented pass-through CQL-to-PQF conversions. Bug #861.
111 Fixed bug #832: Problem with MARC/charset in yaz-client.
113 Fixed bug #668: save command line history for yaz-client.
115 Fixed bug #830: pkg-config support.
117 --- 2.1.48 2007/01/23
119 Extended ZOOM result set options with two options that may be read by
120 a client: resultSetStatus and presentStatus with values as specified for
122 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
124 Fixed bug #827: Using SSL fails on Debian etch.
126 Fixed bug #826: Weird looking chars for set of MARC records.
128 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
129 that is treated as an ItemOrder with itemRequest being an XML document
130 external. The value of "doc" is the content.
132 Extended the GFS search facility. New member of bend_search_rr
133 'estimated_hit_count' signals that hits is known to be an estmate
134 (higher or lower than real hit count). New member 'partial_resultset'
135 signals that the search was partial (hit count is lower or equal than
136 real hit count). For Z39.50, the information is stored in resultSetStatus
137 member of SearchResponse APDU. For SRU, the information is signalled
138 via SRU diagnostic 59: "Result set created with valid partial results
141 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
143 --- 2.1.46 2007/01/13
145 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
147 Added ZOOM_connection_peek_event.
149 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
150 the following new functions:
151 ZOOM_event_nonblock, ZOOM_connection_process,
152 ZOOM_connection_get_{socket,mask,timeout},
153 ZOOM_connection_fire_event_{timeout,socket}.
154 The existing blocking event handler, ZOOM_event, is a wrapper for the
155 + blocking ZOOM_event_sys_{poll,select}.
157 Implemented function ccl_xml_config which parses XML version of CCL
158 configuration (bug #798).
160 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
162 Added timings utility (yaz/timing.h)
164 --- 2.1.44 2007/01/03
166 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
169 Fixed bug #779: Rotation of apdu.log fails.
171 Fixed for character set conversions:
172 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
173 Honor G1 set in MARC-8 decoding.
175 --- 2.1.42 2006/12/17
177 Fixed bug #775: char conversion does not handle Alternative UTF-8
180 Implemented function yaz_marc_read_line which parses MARC line format
181 records. There is a wealth of formats out there. So far, this function
182 reads line records produced by yaz_marc_write_line.
184 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
185 more generic and easier to remember(!) options: -i format and -o format
186 which specifies input format and output format respectively - where
187 format is one of "marc", "marcxml", "line", "marcxchange".
189 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
190 does not print anything except warnings for records.
192 For yaz-marcdump, added support for MARC split into files (-s) with a given
195 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
196 spec, at http://www.loc.gov/standards/sru/record-update/
197 This has changed the binary layout of the following structs:
198 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
199 bend_update_rr . Patch by Ko van der Sloot.
201 Added GFS utility function bend_assoc_is_alive which returns 1 if
202 association is still alive (client is connected); 0 otherwise (client
203 closed connection). This allows busy servers to stop working for
206 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
207 been a separate piece of software. This version of ziffy has been modified
208 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
210 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
212 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
213 Client code may now interrogate options such as "init_opt_sort" to
214 find out whether the server claims to support various options.
216 --- 2.1.40 2006/11/27
218 Added utilities yaz_{set,get}_esn to set/get element set name from
221 Removed the build of libyazthread.la. The libyaz.so is the threaded version
222 of YAZ and has been so since YAZ 2.1.10.
224 Implemented ZOOM_record_error which returns error information for
225 record (surrogate diagnostic).
227 --- 2.1.38 2006/10/31
229 Updates for SRU Update by Ko van der Sloot:
230 1. Changed name from "operation" to "action"
231 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
232 versions in the code, marked as 'backward compatible'.
233 3. Added diagnostics for SRU Update.
235 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
237 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
239 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
241 For GFS, fixed problem with SRU diagnostic 'First record position out of
242 range' being issued for 0 hits.
244 zoomtst10 part of Windows Build.
246 --- 2.1.36 2006/10/13
248 Implemented yaz_filepath_comp which splits a path into file path
249 components (required by Zebra 2.0.3+).
251 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
252 BSD inspired license until now so this should not have any real impact on
253 anybody. See http://www.opensource.org/licenses/bsd-license.php
255 Fixed bug #687: Missing log lines.
257 Fixed bug #678: CQL to PQF translation does not preserve double-quote
260 Fixed bug #689: SRU diagnostics to be added.
262 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
263 whether a connection is idle (no more work do do).
265 --- 2.1.34 2006/10/04
267 Change type of optval from long to int for invocation of setsockopt with
268 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
270 Added support for specifying the max log file size for the Generic
271 Frontend Server. The size is given with option -r.
273 --- 2.1.32 2006/09/21
275 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
277 --- 2.1.30 2006/09/17
279 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
282 Fixed bug in Generic Frontend Server that could cause a server to stop
283 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
285 For the generic frontend server, the maximum record size is used as maximum
286 size of incoming packages (SRU + Z39.50). The value until was previously
287 only used in Z39.50 Init negotiation and, later, in a session controlled
288 sizes of records returned. This is controlled using -k option. It can be
289 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
291 --- 2.1.28 2006/09/04
293 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
296 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
298 New option for yaz-marcdump -lpos=value which allows setting a portion
299 of MARC header to a certain value.
301 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
303 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
304 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
306 --- 2.1.26 2006/08/15
308 Fixed problem with SRU mode type (soap, get, post) for yaz-client
311 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
313 --- 2.1.24 2006/08/08
315 Fixed MARC ISO2709 encoding routines to deal with character set
318 Minor changes to GFS logging. Database included in search request log
321 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
322 cached/multiple records.
324 Shared libraries are built by default on Unix+configure.
326 Changed cql2pqf transformation to use a different evaluation order. The
327 new order is: always, relation, structure, position, truncation, index
328 and relationModifier. Old order was: always, relation, relationModifier,
329 structure, index, position, truncation. Note that the the latter ones
330 override former ones for identical attributes.. The new scheme means that
331 it is possible to override any existing attribute with a relationModifier.
332 And also that it is possible to override everything for the index rule
333 (except the ones listed in relationModifier). No order is perfect but this
334 one, we believe, covers more real cases.. The "always" should have been
335 called "default", since the attributes there can be overridden with all
338 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
339 compilation phase, but also for yaz-config --cflags output. This allows
340 us to have public headers with Libxml2 stuff in them . It should also,
341 eventually, make Libxml2 checks redundant in packages using YAZ, such
344 --- 2.1.22 2006/06/15
346 Changed SRU update structure bend_update_rr so that SRU diagnostics are
347 stored in uri, message and details.. Previously diagnostics were stored
348 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
349 compatibility.. but he's probably the only one affected, so.
351 Added support for CCL, compiled on the client side, in ZOOM-C. This
352 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
353 input; the resulting query objects can be used for for searching with
354 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
356 YAZ' configure searches for OpenSSL by default.
358 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
359 SL_CTX_use_certificate_file. See
360 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
361 for more info. Thanks to Ko van der Sloot.
363 --- 2.1.20 2006/06/02
365 Bug #600: SRU GET, POST support for yaz-client. Introduced
366 command 'sru' which selects method SOAP/GET/POST.
368 Allow missingValueAction to be specified for the sortspec string -
369 function yaz_sort_spec. By default, the missing value action is null.
370 Use ! to specify "abort". Use = followed by stringvalue to specify default
373 Ensured that Present-handler (if defined) is called in GFS before any call to
374 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
375 searchRetrieve requests.
377 Documentation for YAZ is now based on the Docbook XML/XSLT using
378 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
379 is no longer depending on jade/openjade or docbook-to-man scripts.
380 PDF is no longer part of the distribution - but can optionally be
381 made using DSSSL/jadetex or FOP.
383 Added retrieval handling support in Generic Frontend Server to support
384 conversion between MARC/XML as well as XSLTtransforms. See
385 etc/yazgfs.xml for an example.
387 Added Authentication support to Generic Frontend Server in SRU
388 mode. Authentication using HTTP Basic is supported, as is the use
389 of 'x-username' and 'x-password' parameters in the request itself.
391 Added support for a new character set MARC8s identical to MARC8 except
392 that it converts combined characters to single Unicode characters in the
393 Latin-1 range (when possible).
395 --- 2.1.18 2006/04/24
397 ASN.1 compiler 0.4: generates brief Doxygen file header for
398 generated .h/.c files.
400 Utility yaz_iconv now supports conversion to MARC-8.
402 New facilities for the MARC module. The reading - and writing of
403 content are separate methods for the yaz_marc_t handle. The following
404 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
405 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
406 format). Write functions have prefix yaz_marc_write_.. The existing
407 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
408 available. Removed support for OAI-MARC and simplexml (not the
409 simplexml from PHP5).
411 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
412 to be returned for this connection.
414 --- 2.1.16 2006/03/31
416 Allow multiple languages and charsets to be specified with
417 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
418 negcharset iso-8859-1,utf-8
420 Translation of proximity nodes from CQL into PQF now works.
422 Moved to automake 1.8, 1.9.
424 Added function yaz_log_set_handler which allows a log handler to be
425 installed. This handler will be called for all log messages. Output
426 to file is also produced; but that can be disabled by passing NULL
427 fname to yaz_log_init_file.
429 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
431 For SRW (including GFS), accept application/soap+xml as content-type
434 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
435 produces NO stylesheet reference even if a default stylesheet is specified
438 --- 2.1.14 2006/03/14
440 Updated Windows package to include yazd.dll + yazd.lib for the
441 Development component.
443 If the environment variable YAZ_LOG is set, then it is used as a
444 string indicating the default level of logging to use if not
445 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
446 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
447 used as before. So, for example, to omit warnings from YAZ logging,
450 cql_transform() now map structure and other attributes before indexes,
451 so that index-specific structures and other attributes can override
452 defaults. So now a combination of mapping specifications such as:
454 index.dc.date = 1=date-modified 4=5
455 does the right thing.
457 cql_transform() now also respects the "always" mapping specification,
458 which establishes an initial set of attributes to be used for all
459 terms except where overridden by more specific attributes associated
460 with the index, relation or modifier.
462 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
463 which mode to use; one of "post", "get" or "soap" (SRW, default).
465 Fixes for yaz_iconv routines: changed trie-based character set conversions
466 to use only non-negative values for bit fields due to Sun's C compiler not
467 supporting negative values.
469 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
470 sequences where not read correctly. Fix by Rustam Usmanov.
472 Updated win/makefile to use options, settings which makes things
473 compile with VS C 2005.
475 --- 2.1.12 2006/02/01
477 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
479 In ZOOM socket code, use select instead of poll on MacOSX.
481 ZOOM-C now support client-side compilation of CQL into RPN that is
482 sent to the server, enabling CQL to be used against all Z39.50
483 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
484 ZOOM_query object, and submit it using ZOOM_connection_search().
485 The CQL-to-RPN translation uses a configuration file, the name of
486 which must be specified in the Connection's "cqlfile" option.
488 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
489 function, which takes as its start-term parameter a ZOOM_query object
490 (which may have had either CQL or RPN set into it).
493 --- 2.1.10 2005/11/29
495 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
496 GFS to support this as well. Backend handler, bend_srw_update, does the
497 update work. Code contributed by Ko van der Sloot.
499 Allow retrieval of Search Result-1 information in ZOOM by the use of
500 options that are attached to a result set. ZOOM documentation updated
503 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
504 UTF-8 conversion. Patch by Raj Patel.
506 Added option -m to GFS to control formatting of timestamps in log file.
508 Added 'exit' as synonym for 'quit' in yaz-client
510 Added support for specifying SRW resultSetId + resultSetIdleTime in a
511 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
512 for the new members. Patch by Ko van der Sloot.
514 Added support for SRU POST. It is supported for content-type
515 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
517 Do not build the separate Multi-threaded (MT) library libyazthread.la.
518 Instead make the library libyaz.la multi-threaded. Threading as a whole
519 can still be disabled by configure option --disable-threads. Previosly,
520 with older GLIBCs there were problems with MT libs under Apache. This
521 has now been fixed a long time ago.
523 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
526 CQL module modified to be case insensitive for relations/indexes/operations.
528 Fixed bug in CQL transform code: incorrect value relationModifieder
531 Added 'show all' command for yaz-client which retrieves all results
534 Added new yaz-client, xmles, which takes a (private) OID and
535 a document to be sent as an extended service request.
537 Describe new yaz-client commands wait_response and set_auto_wait.
539 Increase TCP/IP listener backlog from 3 (which I am guessing was
540 copied from the SunOS manual entry way back when) so SOMAXCONN, so
541 that the socket will queue as many incoming connections as it's able
542 to handle ongoing connections. In other words, it will never now
543 refuse a connection that it would be able to handle merely because
544 it's not got around to accepting() enough of the pending connections
545 yet. This is the behaviour anyway under Linux, where the listen()
546 argument is ignored; but not under BSD and on systems such as
547 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
548 YAZ-based servers should now be uniform across operating systems in
551 yaz-marcdump uses 64-bit file access on some systems. This is enabled
552 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
553 This allows yaz-marcdump to read large MARC batches (>2 GB).
555 Modified all YAZ source files - except the source which is auto-generated
556 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
559 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
560 corresponding to the existing *_setl() function. These allow option
561 values containing arbitrary valuues.
563 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
564 ZOOM_resultset_sort() in new applications. Its behaviour is identical
565 except that it returns an indicator of whether or not the sort
566 criterion was accepted (0 for OK, -1 for invalid).
570 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
571 MARC output rather than returning "new" buffer.
573 yaz-client warns about unknown init options.
575 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
579 Added support for SRW sort in Generic Frontend Server. Patch
580 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
581 sortKeys - or NULL if none is provided.
583 Fixed bug #307: It was impossible to specify indefinite/no timeout
584 for ZOOM_event. Special timeout value -1 now means indefinite timeout
587 Added support for multiple languages and charsets to be specified in
588 ZOOM. Each charset/language is separated by a blank. If negotiation is
589 in effect in init-response, Option
590 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
591 Code based on patch by Vasiliy Osadchuk.
593 Fixed bug #306: infinite recursion that occurred when calling
594 yaz_log_level_init as the first call (before other log level or
597 Fixed bug in scan handling in front end server: if preferred-Position-In-
598 Response was non-present, a NULL pointer referece was performed.
602 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
603 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
604 now defined for all those error codes. So instead of putting 109 in
605 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
606 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
608 Modified the yaz-marcdump utility to skip garbage bytes between MARC
611 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
613 Program yaz-client now exits and produces an error message if multiple
614 Z39.50 servers are specified on the command line (none or one allowed
617 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
622 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
624 Fixed bug #272: Preserve spacing for CCL terms.
628 Added support for virtual hosts and multiple backend servers for
629 the YAZ frontend server. The configution is XML based and
630 support specificition of CQL to RPN mappings and explain information.
631 See section "Virtual Hosts" in the YAZ manual.
633 Extended OPAC display utility. OPAC display utility renders
634 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
635 to supplement yaz_marc_decode_wrbuf.
637 Fixed a bug in MARC decoder that could caused it to crash for some
638 invalid MARC records. More diagnostics and warnings where added in
639 XML output (warnings, etc are stored in comments).
641 --- 2.0.34 2005/02/08
643 Fixes for UNIX domain sockets. Bug #261.
645 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
647 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
648 Added yaz_marc_subfield_str which defines subfield lead string which is
649 used in YAZ_MARC_LINE format. Default string is blank+$. Added
650 yaz_marc_endline_str which defines end of fields string used in
651 YAZ_MARC_LINE format. Default string is newline.
653 Experimental support for MarcXChange. This format can be produced
654 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
655 http://www.bs.dk/standards/MarcXchange.xsd
657 Added yaz-client commands scansize that sets maximum number of
658 entries to be returned by scan.
660 --- 2.0.32 2005/01/11
662 Added support for SRW scan in yaz-client and Generic Frontend Server.
664 * Added whereInList member to SRW Scan Term.
666 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
668 Fixed NMEM system to return aligned blocks on the smallest boundaries
669 that are suitably aligned for all possible types on the particular
670 architecture YAZ is being built for.
672 --- 2.0.30 2005/01/04
674 Fixed numerious warnings that was issued with newer versions of GCC.
676 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
677 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
680 Make YAZ Generic Frontend Server slightly faster.
682 Enhance (and reduce) logging for Generic Frontend Server.
684 Revert YAZ log system so that it flushes every write operation
685 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
687 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
688 instead of LOG_, due to name clash with syslog(3). LOG_ are still
689 present. New applications should define YAZ_USE_NEW_LOG=1 - this
690 will effectively disable old definitions.
692 --- 2.0.28 2004/11/09
694 Added yaz_log_time_format which specifies log format using
697 Added yaz_log_module_level which returns mask for a module. Value
698 is non-zero mask a if module is enabled; zero if disabled.
700 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
701 in include/yaz/cql.h.
703 Fixed bug #176: Dont throw diagnostics on empty SRU args.
705 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
707 Fixed bug #172: RPM builds does not enable SSL.
709 Doxyfile.in part of dist. Doxyfile generated by configure.
711 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
712 are given and the corresponding component does not exist.
714 Extend CCL documentation in YAZ reference. Describe r=r.
716 --- 2.0.26 2004/10/01
718 Fixed MARC->MARCXML conversion to properly deal with
719 fields, subfields, indicators having non-ASCII characters.
721 Fixed MARC->MARCXML conversion so that ASCII control characters
722 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
725 Added YAZ GFS support for conversion from Z39.50 surrogate
726 diagnostics to SRW surrogate diagnostics.
728 Bug fix: YAZ GFS did not return schema in explainResponse.
730 --- 2.0.25 2004/09/30
732 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
733 now converts recordSchema to elementSetName as well as schema URI.
735 Fixed bug in COMSTACK that prevented HTTP request packages from being
738 --- 2.0.24 2004/09/29
740 Added CCL facility r=r "range" which is similar to r=o "ordered" but
741 does not require white-space before and after the dash in a range, e.g.
742 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
745 Fixed a few AC_TRY_LINK configure tests that did not operate properly
746 due to new GCC removing "redundant" code.
748 Added yaz-client commands scanpos and scanstep that sets preferred
749 position and step-size for scan.
751 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
753 Added CCL utility ccl_qual_buf which parses one or more CCL
754 spec lines in a buffer.
756 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
757 of name and value - ignoring empty lines and comments.
759 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
761 Added odr_get_element_path which returns current element path for an
762 ODR handle. This utility is useful in error handling or user-defined
765 Added ODR_PRINT utility odr_set_stream which is is a more generic
766 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
767 to a write function and pointer to close function. The close function - if
768 non-NULL - will be called during odr_destroy.
770 Fixed bug in CCL parser where truncation char was not removed from
771 right side when truncation=both was in effect.
773 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
776 --- 2.0.23 2004/08/11
778 Fix buffer overrun in CQL parser when dealing with proximity (%).
780 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
781 to UTF-8/UCS conversion is now only based on codetables.xml.
783 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
785 --- 2.0.22 2004/08/06
787 Add support for more "commit changes" in ZOOM (uses Extended Services).
789 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
792 Yet another small fix for configure of SSL.
794 --- 2.0.21 2004/05/14
796 Fix SSL libs for configure when --with-openssl=DIR is given.
798 --- 2.0.20 2004/05/10
800 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
802 SSL comstack now uses yaz.pem certificate file on server side
803 by default. Certificate filename can be configured by calling
804 comstack function cs_set_ssl_certificate_file before cs_bind is used.
806 Fix bug regarding multiple calls to ZOOM_connection_connect.
808 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
810 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
811 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
813 ZOOM now allows inspection of X509 peer certificate for verification.
814 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
816 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
817 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
818 as "modular" but it simplifies things.
820 Added cs_get_peer_certificate to that returns peer X509 PEM.
822 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
823 NULL if SSL is unavailable.
825 Documentation about MARC decoding tools.
827 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
829 --- 2.0.19 2004/03/30
831 Rename CHANGELOG to NEWS to follow GNU style packing.
833 Fix bug with missing initialization of member in init_diagnostics.
834 This bug affects threaded version of GFS server.
836 --- 2.0.18 2004/03/20
838 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
841 Ensure zlib.dll is packed with Windows install.
843 --- 2.0.17 2004/03/17
845 Fix encoding of xsd:string to use text instead of CDATA.
847 Fix endless loop in CQL parser with unbalanced ".
849 Use a more compact way to store MARC-8 conversion tables.
851 --- 2.0.16 2004/03/16 Debian only
853 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
856 Update CQL parser to use new CQL 1.1 modifiers for booleans and
861 --- 2.0.15 2004/03/01
863 Another fix for decoding of XML packed records.
865 --- 2.0.14 2004/02/25
867 Fixes for Chunked encoding. White space not ignored after length spec.
869 Update NS and use default NS for SRW diagnostic elements.
871 --- 2.0.13 2004/02/23
873 Implement ZOOM_resultset_cache_reset which resets record cache.
875 Implement ZOOM_resultset_sort which sorts a result set.
877 Implement chunked HTTP transfer.
879 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
881 --- 2.0.12 2004/02/16
883 Added member 'schema' to bend_explain_rr structure so that backend
884 can specify explain record identifier. Defaults to Zeerex 2.0.
886 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
888 --- 2.0.11 2004/02/16
890 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
893 Added init command for yaz-client which sends "extra" init request.
895 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
896 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
898 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
900 Make ZOOM error code for "invalid query".
902 Fixed compilation for SSL which wasn't properly enabled for all platforms.
904 --- 2.0.10 2004/02/05
906 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
909 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
911 Added option -p <file> to make Generic Frontend Server to write PID file.
913 Added option -D to put Generic Frontend Server in background on its own.
915 Make ZOOM C recognize option "password". If unset, "pass" is used
916 (for backwards compatibility).
918 Fixed a bug in Generic Frontend Server that could make it crash if a
919 client sets characterSetNegotation bit, but didn't pass negotiation stuff
922 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
923 Must be issued before open, in order to be in effect.
925 --- 2.0.9-6 2004/01/12 Debian/Windows
927 Make the SRU server more picky WRT unknown params, etc.
929 Bug fix: ZOOM scan response didn't return displayTerm - when present.
931 New YAZ client command, options, that sets Z39.50 options.
933 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
934 options from a string of tokens (one token for each option bit).
936 Update SRW diagnostic code messages.
938 --- 2.0.9-5 2004/01/07 Debian/Windows
940 Handle user defined stylesheet for SRW/SRU.
942 --- 2.0.9-4 2004/01/06 Debian/Windows
944 Fix bug in decoding of Content-Length.
946 --- 2.0.9-3 2004/01/06 Debian/Windows
948 Fix a bug with decoding of XML packed records.
950 --- 2.0.9-2 2004/01/05 Debian only
952 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
954 Fix bug in SRW/SRU diagnostics decoding.
958 Fixed bug in Generic Frontend Server which could drop records exceeding
959 preferred message size. Reported and fixed by Irina Dijour.
961 Fixed calculation of package size for structured records in Generic
962 Frontend Server. Reported and fixed by Irina Dijour.
964 Fixed namespace for SRW/SRU diagnostics.
966 Fixed SEGV in yaz-client that occured for HTTP connection errors.
970 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
971 this version is incompatible with version 1.0 and older YAZ SRW/SRU
974 CQL changes to reflect recent changes to the specification:
975 * Documentation talks about context sets instead of index sets.
976 * Documentation talks about indexes instead of qualifiers.
977 * The CQL-to-PQF transformer's configuration file now uses
978 "index.set.name = <attributes>" instead of the old form
979 "qualifier.set.name = <attributes>". (Both forms are still
980 understood but the latter is deprecated.)
981 * CQL terms with no explicit index specified are now interpreted as
982 cql.serverChoice instead of srw.serverChoice (which of course
983 behaves exactly the same.)
987 MARC conversion can now generate ISO2709 output in another
988 character set. yaz-marcdump uses this facility if you invoke it
991 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
992 functions from there can be used from C++.
996 Frontend server now transfers memory from decoded packages to stream
999 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1000 references to show up.
1002 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1003 the ZOOM Abstract API. The older names for the same options are still
1004 also supported for the benefit of old applications.
1006 ZOOM-C supports "implementationId" and "implementationVersion" options
1007 to go along with "implementationName". These allow the user code to
1008 specify identification strings to be sent to servers.
1009 Add OID for the new ExtLite attribute set.
1011 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1012 as requested/supplid by Ere Maijala <ere@atp.fi>
1014 For generic frontend server, reverse the order of
1015 "toolkit-supplied / application-supplied" strings sent as implementationId,
1016 Name and Version. Also, remove the spaces around the slash. This brings
1017 the GFS in line with the behaviour of ZOOM-C on the client side.
1019 Add function ZOOM_scanset_display_term.
1021 yaz-client shows scan displayTerm if present.
1023 Utility yaz-iconv is now installed by default along with the man page
1026 Extend configure check for OpenSSL to use pkg-config where available (such
1029 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1030 server to specify uid/gid/mask for socket using the format
1031 unix:[user=uid,][group=gid,][umask=mask,]file=path
1032 If file= is omitted the existing format is assumed, e.g.
1034 in which case the mask is 0666 (rw for everybody).
1036 Major restructure of YAZ source. All source in libyaz is in src directory.
1037 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1038 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1040 Added man page for utility yaz-marcdump (used to be called marcdump).
1041 yaz-marcdump is installed by 'make install'.
1043 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1044 of incoming package failed.
1046 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1048 Change prototype of odr_perror: add const to message string.
1050 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1052 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1053 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1054 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1055 DNS lookup. There should not be any compatibility problems with this
1056 assuming that blocking=1 or 0 is used.
1058 Fix bad reference in UNIX comstack in function cs_addrstr.
1060 Fix for compilation on AIX.
1062 The generic front-end server (server/seshigh.c) now supports returning
1063 Init diagnostics to the client in User-information-field, in
1064 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1067 --- 2.0.4 2003/09/04
1069 Allow any CQL relation (not just all,any,exact,scr).
1071 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1072 that features the same UI.
1074 Implemented command update0 in YAZ client which is equivalent to
1075 update but uses old of Ext Update ASN.1.
1077 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1078 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1079 Previously no OID was used for this info.
1081 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1082 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1083 returns 'malformed search term' otherwise.
1085 SortResponse member resultCount now set to NULL in sort handler of
1088 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1091 Add three new utility functions for translating OIDs between various
1092 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1093 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1094 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1095 char *oid_to_dotstring(const int *oid, char *oidbuf);
1096 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1098 Reverted modifications for ES Update definition for z_IU0Update
1099 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1100 is back to YAZ 2.0.2.
1102 String value attributes for CCL parser.
1104 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1105 which their FirstSearch server returns in Init responses, sometimes
1106 carrying useful diagnostic information when Init fails. This has the
1107 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1108 "z39.50/oclcui.asn", where its definition is somewhat different from
1109 what OCLC document on their web-site, as required to interoperate with
1112 Support for anonymous authentication in yaz-client. Use the command
1115 * Fix the OID of the Index Data-local "admin" Extended Service from
1116 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1117 the 1000, which indicates a locally-defined OID, was a mistake.
1119 --- 2.0.3 2003/06/20
1121 Fix CCL directive @case handling so that it affects string match for
1122 both CCL keywords and qualifiers.
1124 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1125 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1126 Decoder has been updated with ASN.1 changes as listed in
1127 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1128 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1129 z_IUUpdate, remains unchanged.
1131 ZOOM_record_get may now return a record in a specific character set.
1132 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1133 "from" is the character set of record as returned by target. "to" is
1134 the character set to be returned. If omitted, "to" is UTF-8.
1136 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1138 New ODR utility, odr_getelement, which returns name of element for
1139 which encoding/decoding failed.
1141 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1142 in cases where a required element was omitted.
1144 Bug fix: some MARC8 sequences were not converted.
1146 New ZOOM option "step" which specifies number of records to be
1147 retrieved in one chunk. Used in conjunction with "start" and "count".
1149 SRW support for yaz-client. Use scheme http: to use it, e.g.
1152 yaz-client no longer does (un)intelligent character set conversions
1153 by default. Can be enabled with charset and marc_charset commands.
1155 xmalloc trace fix for 64-bit systems such as DEC alpha.
1157 Solaris 2.6 compile fix.
1159 New function, cql_strerror() translates SRW error codes, as returned
1160 by cql_transform_error(), into human-readable English strings. Used
1161 in yaz-client diagnostics when appropriate.
1163 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1164 converts it into a type-1 query which is sent to the server. This
1165 makes CQL available for use with all Z-servers, as opposed to the tiny
1166 minority that can handle CQL queries themselves.
1168 --- 2.0.2 2003/04/28
1170 New Debian package layout similar to the Redhat Package layout.
1172 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1173 and search result respectively.
1175 --- 2.0.1 2003/04/25
1177 Redhat package is now several packages: libyaz (runtime libraries),
1178 libyaz-devel (development and documentation, and yaz (utility programs).
1179 Package spec file by Morten Bøgeskov.
1181 New member 'schema' in struct bend_fetch_rr which the name of requested
1182 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1183 handler MAY set this to reflect the schema of the returned record.
1185 New member 'display_term' in struct scan_entry. GFS now sets member entries
1186 and allocates scan entries to be filled by user scan handler. In previous
1187 version, entries member was allocated by the scan handler. That still works,
1188 but the GFS will ignore member display_term - assuming it was NOT set by
1189 the handler. The fact that the GFS now allocates the entries both allows
1190 for new members and makes a scan handler easier to write.
1192 Fix CQL lex buffer overflow.
1194 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1195 SRU default recordPacking is string.
1197 SRU protocol support for frontend server.
1199 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1201 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1203 Added scan for the ZOOM shell (zoomsh).
1207 * String Identifers for Schemas (Amendment 5).
1208 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1209 Old definition for schema
1210 Odr_oid *schema; /* OPT */
1215 Z_InternationalString *uri;
1216 #define Z_Schema_oid 1
1217 #define Z_Schema_uri 2
1220 * resultCount parameter to Sort Response (Amendment 1).
1221 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1223 Support for SRW 1.0 over HTTP. This is an optional feature and
1224 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1227 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1228 on the same port. SRW SearchRetrieveRequests are mapped
1229 to bend_init,bend_search,bend_fetch,bend_close.
1231 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1233 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1234 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1236 ZOOM connections are SRW based if schem http is used for hostname
1237 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1238 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1240 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1241 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1242 distance=n, order=true/false, relation=le, prox unit=word. If
1243 n is omitted, distance 1 is used.
1245 Fixed problem with C compiler include path in wrong order.
1247 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1248 on Solaris. Patch from Ko van der Sloot.
1250 New MARC decode API. All new functions operate on a yaz_marc_t
1251 handle. The most important new functions are: yaz_marc_create,
1252 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1253 decode and destroy respectively. Decoder can produce formats
1254 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1255 include/yaz/marcdisp.h.
1257 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1258 to UTF-8, UCS-32, wchar_t or Latin-1.
1260 * Prototypes for yaz_iconv_-functions moved to separate header
1261 include/yaz/yaz-iconv.h.
1263 Make a few private functions 'static' in unix.c. This prevents
1264 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1266 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1267 are set when Init Response is received.
1269 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1270 but returns diagnostic set as well.
1272 New function yaz_strerror which is a portable wrapper for
1273 strerror/strerror_r/GetLastMessage.
1275 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1276 is returned for MARC. If type is "oai", then OAI MARC is returned.
1278 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1281 --- 1.9.2 2002/11/26
1283 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1285 Fix bad race conditions on SIGTERM and terminate gracefully in
1288 Move retrieval (data1) module to Zebra since nobody seems to be
1291 Add GRS-1 render for ZOOM using same format as yaz-client.
1293 --- 1.9.1 2002/10/05
1295 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1297 Fix broken ESpec handling in data1 module.
1299 SGML reader parses comments and makes them part of the data1 tree.
1301 Added several type casts so that YAZ compiles as C++ code.
1303 ZOOM didn't handle PDU encoding failures properly.
1305 Added more Bib-1 diagnostics (approved extensions).
1307 GNU configure: better check for iconv.
1309 More portable use of accept, getpeername. Check for socklen_t. Use
1310 int/size_t if socklen_t is not defined.
1314 PQF parser rejects bad queries - including those with extra
1315 characters in them. PQF parser used to silently ignore that.
1316 Cleaner API for PQF added, which allows you to get detailed
1317 error information for bad queries (see yaz/pquery.h).
1319 Fixed bug in ZOOM_record_get for type "database".
1321 Implemented mini iconv library supporting conversions between
1322 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1324 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1326 --- 1.8.9 2002/08/20
1328 Fixed ZOOM C record cache so that preferredRecordSyntax and
1329 elementSetName is used to check for already fetched records.
1331 --- 1.8.8 2002/08/02
1333 Added three members in bend_initrequest structure to facilitate
1334 character set negotiation.
1336 Fixed a bug in frontend server that could cause indefinite
1337 loops under rare conditions.
1339 Revised character set utilities (charneg.h) so that encoding
1340 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1342 For PQF, directive @term <type> sets term type for Scan/Search.
1343 Here <type> is general, string, numeric, null. The term type
1344 is inherited - just like @attr.
1346 New call odr_set_charset that sets character set conversion for
1347 international-strings on a ODR stream. Prototype is:
1348 int odr_set_charset(ODR o, const char *to, const char *from);
1349 The InternationalString is still represented as C string in YAZ
1350 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1351 won't). On the protocol level, you can use any encoding.
1353 Support for UNIX sockets in ZOOM.
1355 Solaris recv sometimes returns errno == ENOENT. It is treated as
1356 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1358 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1359 both client and server. Code by Morten Bøgeskov.
1361 --- 1.8.7 2002/05/22
1363 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1364 that they can be used directly from Visual Basic. You must recompile
1365 your windows APP if you're using ZOOM.
1367 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1368 Commands "lang" and "charset" sets language and character set respectively.
1369 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1370 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1372 Attributes from multiple CCL fields may be OR'ed rather than merged
1373 using directive "@field or". Fields are still merged by default -
1374 equivalent to "@field merge".
1376 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1379 Fixed bug in zget for parameter ExtendedServicesResponse.
1383 --- 1.8.6 2002/03/25
1385 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1387 Client displays USR.1:SearchResult-1 (hits per term).
1389 Additional Search Info for search in Generic Frontend Server.
1391 Fixed CCL parsing of "field=s".
1393 WIN32 installer - using the excellent NSIS software from nullsoft.
1395 Fixed CCL parsing of "field = - <number>".
1397 Added function yaz_marc_decode that decodes MARC for line mode
1398 display or XML (similar to that used by JZKit).
1400 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1401 Z39.50. But ISO/ILL was, however.
1403 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1404 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1407 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1409 --- 1.8.5 2002/02/03
1411 New YAZ client features: Command completion and new commands:
1412 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1413 Code provided by Jacob Poulsen.
1415 New call oid_trav, that visits all registered OIDs via callback.
1417 Function ZOOM_record_get now returns const char pointer rather than
1418 void pointer. It saves a lot of type casts.
1420 For YAZ client, command "auth" now allows you to set authentication
1421 in IdPass style. It is enabled when three tokens are given - order
1422 is user, group and password.
1424 Fix memory leaks in MARC record handling for ZOOM.
1426 New option for YAZ client, -k <kilobytes> that sets
1427 maximum record size. Similar to -k option for generic frontend
1428 server and yaz-ztest.
1430 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1432 Prefix query parser reports "fail" when bad attribute set is given.
1434 Fix in MARC decoder. Proximity logging. Fix for attribute set
1435 in scan handler for server. Patches by Shigeru Ishida.
1437 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1440 Configure option --with-openssl=<dir> now works when a directory is
1441 specified. Patch provided by Morten Bøgeskov.
1443 New option for YAZ client, -u <auth>, that sets authentication.
1445 ZOOM fix: error information was sometimes "missing", since error
1446 was cleared/reset too when it shouldn't.
1448 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1450 --- 1.8.4 2002/01/04
1452 Scan for ZOOM API. New object ZOOM_scanset. New functions
1453 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1454 ZOOM_scanset_destroy.
1456 New ZOOM function, ZOOM_connection_last_event, that returns type
1457 of last event (such as "receive data", "send data", "apdu received",
1460 New ZOOM option, schema, that specifies schema for retrieval.
1462 New CCL feature. Qualifiers can be aliases for one or more
1463 other qualifiers (if more than one is given, OR is used).
1465 ZOOM uses named result sets if target supports it.
1467 Two new YAZ client commands: . (dot, which sources a script of YAZ
1468 client commands), and ! (to execute shell command.). Implemented
1471 Working on Debian packages.
1473 --- 1.8.3 2001/11/19
1475 YAZ client enables named result sets only if target supports it.
1477 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1479 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1480 with key="host" to get same result.
1482 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1483 Function Z3950_resultset_record(s) returns references to records
1484 "owned" by resultset. To become owner use Z3950_record_clone.
1486 Function z_ext_record handles Extended Services. Thanks to
1489 --- 1.8.2 2001/11/12
1491 CCL Parser fix: ignore token comma when dealing with and-lists.
1493 Documentation updates for COMSTACK.
1495 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1496 Changed prototype Z3950_records. For some functions, int parameters
1497 were changed to size_t.
1499 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1502 New MARC decode/display function, marc_display_exl, which properly rejects
1503 non-ISO2709 records. YAZ client uses it.
1505 --- 1.8.1 2001/10/29
1507 Fix bug: local attribute set wasn't set correctly in PQF strings.
1511 * Old Z39.50 codecs no longer supported.
1513 Added ZOOM C binding. See http://zoom.z3950.org/
1515 Renamed states for COMSTACKs to avoid confusion with events.
1517 Implemented cs_look and proper cs_rcvconnect.
1519 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1521 Configure detects POSIX threads on OpenBSD.
1523 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1524 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1526 When error is returned from present handler, non-surrogate diagnostic
1527 is returned in present response (and fetch handler is no longer called).
1529 * Minor adjustments to pquery parser (PQF). Token characters may be
1530 escaped by using backslash (C-style).
1532 PQF parser allows string attribute values to be specified. For @attr,
1533 non-numeric characters after the equal-sign are treated as strings
1534 (e.g. @attr 9=title).
1536 CCL trunction character may be defined (@truncation in file)
1538 * function zget_ExtendedServicesRequest sets waitAction to
1539 waitIfPossible (was wait).
1541 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1544 CCL operator names may be set in field definition files (CCL_bibset).
1545 See ccl/bib1 for an example.
1547 Fixes in ASN.1 compiler for C++ compatibility.
1549 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1550 and "op_or" to avoid conflict with C++.
1552 Fixed problem with GNU readline detection on Redhat 7.0.
1554 Added step-size for Scan backend handler.
1556 Fixed bug that made the frontend server crash when no attribute
1557 set was specified for scan.
1559 Front-end server automatically switches to original working directory
1560 when installed as an NT service. Previously -w had to be specified to
1563 Added extended attributes for retrieval module (data1), so that data1
1564 records carry d1_readXML/SGML attributes. d1_read also supports
1565 null-data rules ( <tag/>)
1567 On UNIX when POSIX threads are available, a separate library libyazthread
1568 is created. Programmers should link with that library and the yaz library
1569 when using threads. The reason for the split was that some applications
1570 on Linux, such as Apache, doesn't work well when using shared objects that
1573 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1574 (or any frontend server) in SSL mode by specifying ssl: followed by
1575 address. Only tested on UNIX.
1577 Added feature for CCL module. Virtual structure s=al or s=ol generates
1578 and-list and or-list respectively instead of phrase search.
1582 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1583 log_mask_str. This was done to avoid name conflicts with other libraries
1584 (such as other PHP extensions).
1586 Added raw OID member for preferred record syntax (request_format_raw)
1587 and returned record syntax (output_format_raw) for backend fetch method.
1589 Config file yaz-config now accepts options so that it returns specific
1590 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1592 Shared library support for UNIX using GNU libtool.
1594 * Modified backend interface. Request/Response struct's replaced by
1595 one read/write C struct. For example bend_fetchrequest and
1596 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1597 Every handler - even search has to be registered in bend_init
1598 handler. This means that the YAZ library no longer refers to
1599 external functions and it makes it possible to make the whole
1600 thing a single DLL/SO.
1602 Added Segment handler for backend server.
1604 Added Zmbol/Zebra administrative functions to YAZ client.
1606 Threaded frontend server on UNIX (when POSIX Threads are available).
1607 Starting the server with option -T enables multi-threading.
1611 Added configure option --enable-comp/disable-comp to control use
1612 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1613 located in sub directory asn.
1615 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1616 in ${exec_prefix}/bin along with the other programs yaz-client and
1619 GNU automake used to maintain makefiles.
1621 Added several OID's.
1623 Changed retrieval module so that we can load records with no abstract
1624 syntax defined. Tagpaths in these records are fully composed of string
1627 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1631 On UNIX, the generated makefile now supports a proper 'make install'.
1632 The prefix can be set via GNU configure to set the install location
1633 (default is /usr/local).
1635 * YAZ programs client and ztest were renamed to yaz-client and
1636 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1637 locations, such as /usr/bin,/usr/local/bin,etc.
1639 * YAZ Header files were moved from include to include/yaz. YAZ Header
1640 files are referred to as include <yaz/log.h> rather than <log.h>.
1641 The YAZ include path (-I ..) is therefore the same as before. Programmers
1642 should update their #include statements or use -Ipath/include/yaz
1643 instead. The main motivation for doing this change is that YAZ header files
1644 can be installed in "standard" locations /usr/include,/usr/local/include
1645 without introducing conflicts, since ALL YAZ header files are stored
1646 in subdirectory yaz (under /usr/include for example).
1648 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1649 rather than project/workspace files. We switched because project files
1650 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1653 Changed name of logging function, logf, to yaz_log, to prevent name
1654 clash with some math-log functions. The YAZ header log.h defines logf
1655 to yaz_log (#define) so there should be no incompatibilities by this
1658 Added bend_start/bend_stop handlers for server. These handler are
1659 called on start/stop of server. For windows they are called whenever
1660 a service is started/stopped.
1662 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1663 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1664 in util/yc.tcl. The auto-generated C code structures are, in a few
1665 cases, incompatible with the old decoders. There are differences in the
1666 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1667 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1668 The preprocessor variable ASN_COMPILED is defined when the compiled
1669 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1670 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1671 wish to use the old encoders/decoders you can specify --disable-yc
1674 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1675 version so that it supports both new - and old version of DB Update
1677 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1678 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1679 change. The name parameter can be set to 0 in which no name is specified
1680 for the construction. The macros odr_implicit and odr_explicit sets name
1681 parameter to zero for the construction involved. New macros
1682 odr_implicit_tag and odr_explicit_tag are similar to the others,
1683 except that a name parameter is added. For programmers' that don't use
1684 ODR they probably only need to change the call to z_APDU and z_External.
1686 Added access control facility by interfacing the TCP wrapper library.
1687 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1688 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1689 name of the daemon and enables the access control as specified in
1690 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1692 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1693 den Dool <H.M.vdnDool@kub.nl>.
1695 Added reference ID parameter to most functions in server API - refer
1696 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1698 Changed name of ccl library to libccl.a (was ccl.a).
1700 Fixed bug in decoder for Explain (Category TargetInfo).
1702 Added support for GNU readline in client. Thanks to Jacob Poulsen
1703 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1705 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1706 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1707 IMPLEMENTATION! This change was made to the development version before
1708 the ZIG decided to retract the amendment. If any users MUST be
1709 compatible with the original Update definition, PLEASE CONTACT US, and
1710 we will include a separate definition corresponding to the old Update
1711 ES. Note that because of the change to the ASN.1 of the
1712 TaskPackageRecordStructure we cannot define a single structure that
1713 will support both versions.
1715 * Added const modifier to buffer parameter for some ODR/BER encoding
1716 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1717 completeWAIS, odr_dumpBER.
1719 Fixed bug in client.c which caused a crash when a scanResponse didn't
1720 contain positionOfTerm.
1722 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1723 * will cause an error in a client if a non-YAZ target sends both a
1724 * list of Scan entries and non-surrogate diagnostics.
1726 Retrieval module enhancements. Tag sets may be typed in the reference
1727 to it. From the .abs-file the "tagset" directive takes a third optional
1728 integer type for the tag set referenced. From a .tag-file the "include"
1729 directive takes a third optional type as well. The old "type" directive
1730 in the tag set itself is still recognized but acts as the default type
1733 Backend interface change. Individual Scan terms returned from bend_scan
1734 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1735 in include/backend.h.
1737 Retrieval module enhancements. Multiple tag sets and attribute sets may
1738 be specified in abstract syntax specs. Revised the error/warning for
1739 logging messages reported by the retrieval module when reading the
1742 Object Identifier system (oid_..) changed. The API is backwards
1743 compatible but the oid-routines now allocates new OID's when needed.
1744 Raw OID's may be specified in oid_getvalbyname.
1746 YAZ now uses GNU configure to generate Makefile(s).
1748 * Minor changes in some of the member names of DeleteResultSetRequest and
1749 DeleteResultSetResponse. See include/proto.h.
1751 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1752 and added member 'languages' in TargetInfo (which was missing).
1754 Changed the way attribute sets are handled in the retrieval
1755 module. These are now cached, just like the abstract syntaxes
1758 Changed YAZ so that it links with compiled ASN.1.
1760 Added Explain-schema definitions and mapping routines. The following
1761 Explain categories have been implemented: AttributeDetails,
1762 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1764 Fixed minor bug in Windows version of Server Library.
1766 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1768 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1770 Added EXTERNAL: UNIverse Resource Report (non-standard).
1772 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1773 ENUMERATED and SET OF.
1775 * Added 'const' to some of the char pointer arguments for the
1776 functions, data1_read_node, data1_getelementbytagname,
1777 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1780 Fixed bug in data1_insert_taggeddata - the last_child member of
1781 parent wasn't initialised.
1783 * Changed data1_read_record and data1_read_node so that the supplied
1784 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1785 doesn't refer to any parts of the "SGML"-buffer.
1787 Fixed bug in server library (Windows version of statserv_remove).
1789 * Changed code so that it compiles as C++. The type definition
1790 of Odr_fun which is a member of Odr_arm was changed. The result is,
1791 that an explicit typecast is needed for the fun pointer when
1792 using Odr_arm - as in:
1793 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1795 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1797 Implemented the new structured date and time definition as approved
1798 by the ZIG. Added schemaId element to the specificTag in Espec-1
1799 (also approved at the last ZIG). Thanks to RVDM.
1801 Added some Object identifiers (RVDM).
1803 Changed the Update Extended Service (RVDM).
1805 Added command "refid" to client which specifies referenceId for
1806 the following requests.
1808 Implemented extended service handling for server. See ztest.c
1809 for an example as well as backend.h. New handlers are registerd
1810 in the Init handler.
1812 * Changed interface for sort in server.
1814 Added new members to statserv_options_block. It allows a server
1815 to read options from another source than just the command line. Thanks
1816 to Charles Woodfield.
1818 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1819 renamed to zboolean. Some C++ compilers complained about the name.
1821 Minor changes to gils.abs. Added index 's' (sort) on title
1822 and date/time-last-modified.
1824 --- 1.4pl2 1998/1/30
1826 Fixed bug in server library regarding inetd mode (-i). This bug
1827 was introduced by release 1.4.
1829 --- 1.4pl1 1998/1/29
1831 Added sort facility in client and backend server interface.
1833 Fixed problem with dependencies in Makefile(s).
1835 Fixed bugs for encoders/decoders of extended services and
1838 Implemented sub-tree feature for schemas. Sub-trees are
1839 referenced in *.abs-files. See explain.abs for an example
1840 of the use of this feature.
1842 Modified bib1.att; local attributes for ANY didn't include
1843 ANY itself (only affects use of the retrieval module).
1845 Fixed bug in plain SGML reader in function data1_read_node:
1846 tags with prefix "var" was incorrectly interpreted as variants.
1848 Added feature "sub-schemas" to enable references to - and definitions
1849 of - group of elements.
1851 * Removed member parent from type data1_element (in data1.h).
1853 Implemented function odr_nullval() that returns the value of
1856 * Removed member num_children from data1_node (in data1.h).
1858 Made NT service interface part of the server library. The
1859 function statserv_main uses the NT service when required and
1860 calls the statserv_start / statserv_close routines.
1862 Routine zget_SearchRequest and zget_PresentRequest fills
1863 resultSetName/Id member with "default" instead of "Default".
1865 Fixed memory leak in server. Request queue member wasn't freed.
1867 Fixed nmem_exit so that memory is freed.
1871 Revised the CCL parser utility to be thread safe.
1873 Added function, oid_ent_to_oid, to replace the function
1874 oid_getoidbyent, which is not thread safe.
1876 * Added nmem_init and nmem_exit to initialize and release
1877 NMEM resources. Function nmem_init should be called once in the
1878 initial thread before NMEM/ODR is used. statserv.c and client.c
1879 have been changed accordingly. The change was necessary to make
1880 NMEM thread safe. The NMEM memory pool is shared amongst threads
1881 in a process. Unix-based applications will still work fine without
1884 Added NT Services interface for the the Z39.50 (statserv) Server.
1885 Refer to the ztest.c source on the usage.
1887 Windows 95/NT port using MSVC5.0. Project files are included in the
1890 * Defined new 'global' handle for the retrieval (data1) system. The
1891 new handled, data1_handle, describes the state of the data1 system.
1892 This handle is passed as first argument to virtually all
1893 data1 related routines. The functions data1_create and data1_destroy
1894 creates and destroys a data1 handle respectively.
1896 Added ODR encode stream member to all backend request structures
1897 init, search, scan etc. This stream should be used to allocate all
1898 memory used for the response when thread safe operation is needed.
1900 Changed the comstack utility, cs_addstr, to be thread safe. The
1901 returned hostname string returned by the function is now part the
1904 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1905 function. The cs_straddr takes a COMSTACK handle as argument, so this
1906 function must be used after cs_create and before bind/connect.
1907 This function is thread safe.
1909 Moved test server to 'ztest' directory - generic server code still
1910 in 'server' directory.
1912 Made prefix query (pquery.c) utility thread safe.
1914 Added new function modifier YAZ_EXPORT to 'export' public DLL
1915 functions when using windows (see include/yconfig.h).
1917 Added definitions to the OID database (util/oid.c) (RVDM).
1919 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1921 Added call to ccl_rpn_delete in client program.
1923 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1924 release of RPN structure.
1926 Added support for C++, headers uses extern "C" for public definitions.
1927 With input from RVDM.
1929 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1930 Thanks to Ronald van der Meer (RVDM).
1932 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1934 Added support for private extensions to the OID database
1935 (oid_setprivateoids()). Thanks to RVDM.
1937 Added optional, physical ANY (key replication)
1939 Fixed null-reference problem in GRS-1 output filter.
1941 Proximity operator added to Prefix Query Format (PQF).
1943 In test client command "base" accepts multiple databases.
1945 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1949 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1951 Smallish bug-fixes in the new encoders/decoders (explain).
1953 Bug fixed in DeleteRequest.
1955 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1957 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1959 Added SOIF syntax (using private OID for now) to retrieval module and client.
1961 Added Update extended service.
1963 Added SearchResult-1 additional info structure.
1965 Added optional CCL (ISO8777) interpreter as separate module. Available
1968 --- 1.2 1996/6/10 (1st anniversary release)
1970 Added Summary record syntax. Lightly tested.
1972 Added OPAC record syntax. Untested.
1974 Added ResourceReport service encoders/decoders. Untested.
1976 Fixed bug in z_Unit - wrong tagging on unitSystem.
1978 Fixed bug in the DiagRecs decoder.
1980 Added options for max PDU size and session timeout to frontend-server.
1982 Added documentation of query-language parsers and other supporting utilities.
1984 [frontend-server] Added Attribute set to the bend_scanrequest API.
1986 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1987 surrogate diagnostics were generated.
1989 [retrieval] Allow multiple local values for attribute.
1991 [retrieval] Allow multiple attributes per element in .abs files. index type.
1993 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1995 --- 1.1pl2 1996/4/10
1997 Minor changes, mostly specific to Zebra's requirements (retrieval)
2001 Repaired bug in frontend server when running multiple listening
2002 endpoints in dynamic mode.
2004 z_External() now won't break if a known, ASN.1 value comes encapsulated
2005 in an octet-string. The value will pass through unmodified in an Odr_oct.
2007 Added a bit of code to the demo client to decode & display
2008 ASN.1-structured records represented in the octet-aligned branch of
2009 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2011 Added z_ext_getentbyref() to the ASN module. Doc updated.
2013 * Completed the SCAN definition in the ASN module. This may break SCAN
2014 code based on older YAZ-versions at compile-time. The fix is easy -
2017 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2018 under the SCAN definition. Remember to initialize this, server-people.
2020 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2021 that this does not extend to ODR and ASN.
2023 Comstack allows insertion of established socket (primarily for
2024 inetd-operation of servers). Doc updated.
2026 Front-end server can now start from the inetd in TCP mode. Doc
2029 --- 1.0pl4 1996/1/24
2033 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2034 the rank and record number.
2036 Adjustments to the frontend server.
2038 Fixed diagnostic BER dumper. It ignored the file argument.
2042 Various changes to retrieval module.
2044 Changed the union discriminators of the protocol files from enums to
2045 ints paired with #defines.
2047 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2050 *Changed operator in the RPN structure to 'roperator', again to avoid a
2053 Fixed problems in Explain decoders/encoders.
2055 --- 1.0pl2 1995/12/6
2057 Memory bug in log module fixed.
2059 --- 1.0pl1 1995/12/5
2061 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2063 Bug in Explain DatabaseInfo module fixed.
2065 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2069 The shift to v1.0 signals that we now consider the *core* functionality
2070 of YAZ reasonably stable (the core being more or less equivalent to
2071 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2072 tested (Explain not at all - though that will happen soonish).
2074 Minor changes to code to support Windows port.
2076 Various minor changes after we're getting to use GRS-1 & co. more.
2078 Added Espec-1 format.
2080 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2081 of the protocol and it cannot be selected when encoding (maps into 'string'
2082 when decoding). Needed to talk to some servers.
2084 Demo client can request simple element set names.
2086 Added Diagnostic Format encoders/decoders.
2088 Added simple Close handling to frontend server (no hooks for resource
2089 reporting yet), and demonstration client.
2091 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2093 --- 1.0b3 1995/08/24
2095 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2096 handled incorrectly when records were requested in the searchResponse. This
2097 will only affect you if you use the frontend-server.
2099 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2100 Test-client will ask for and print GRS1. Ztest will return dummy records
2103 Added Explain encoders/decoders to the service-level API. Untested.
2105 Added Extended Services: Item Order encoders and decoders to the Service-
2106 level API. Untested. We could use a recent copy of the pertinent bits
2107 of the ILL protocol to add those bits.
2109 Added diagnostic format 1 encoders/decoders to the service-level API.
2112 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2113 odr_cons.c, which causes a more correct output.
2115 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2116 was always set to 0 when no records were requested in the searchRequest.
2118 * Added better external-handling. This shouldn't harm old code that
2119 *encodes* externals. It can break code that looks for a
2120 'single-ASN1-type' representation, since those types that are known
2121 are now decoded immediately. Look at the SUTRS sample code in
2122 seshigh.c and client.c. Documentation updated.
2124 Handling of structured records in bend_fetchresponse. Length -1 marks
2125 structured record, type is deduced from format field.
2127 --- 1.0b2 1995/06/27
2128 Fairly quick maintenance release to add SUTRS support.
2130 Fixed handling of SUTRS records in the demonstration client.
2132 * Added format field to the bend_fetchrequest and bend_fetchresponce
2133 structures of the backend API (frontend server). When the record is
2134 returned, the value of the format field is mapped to an OID. The
2135 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2136 of the record. The special value VAL_NONE in the bend_request means
2137 that no specific format was requested by the client. Documentation
2138 updated accordingly. Test server (ztest) will return a fixed dummy
2139 SUTRS record if your client requests SUTRS.
2141 Documentation updated accordingly.
2143 You can now set external libraries and RANLIB support in the top-level
2147 First public release.
