1 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2 write handlers no longer carries a 'last' parameter. This will make
3 yaz_iconv flush "less" characters. A flush is performed by call to
4 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
6 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
7 removed, because function yaz_query_to_wrbuf does the same.
9 API changes to ZOOM. Functions for setting options returns int, rather
10 than void, so we have a way to flag unknown options. ZOOM_resultset_sort1
11 has become "the" ZOOM_resultset_sort. (and old ZOOM_resultset_sort is removed).
12 ZOOM_connection_scan1 removed. The generic scan is ZOOM_connection_scan
13 and the ZOOM_connection_scan_pqf is a handy short-hand taking a PQF string
16 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
17 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
19 Deprecated functions for yaz_marc-removed.
21 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
24 Branch split: YAZ_2_1_55_branch
28 Fix to ZOOM-C so that transparent reconnection is properly handled on
29 connections that are in asynchronous mode.
31 Fixed compilation on OpenBSD 4.0.
33 Large strings in GRS-1 records are now properly displayed in yaz-client.
35 Added character conversion support for "advancegreek"; based on patch from
38 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
39 sequence is met. Before the error was not set so it would be unknown.
41 Adjust yaz-marcdump MARC reader so that it skips until record separator
46 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
47 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
48 fd_set structure used as a bitmask for the FDs to be selected on.
50 Using ACX_PTHREAD macro to check for POSIX threads.
52 Fixed have-vsnprintf check.
56 Fixes for configure on BSD. Bug #900.
58 Added snprintf/vsnprintf wrappers for systems that don't have
59 limits (heavens forbid).
61 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
62 created before all previous tasks were completed and removed from the
63 task queue, the new task could be removed by a mistake.
65 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
67 Implemented pass-through CQL-to-PQF conversions. Bug #861.
69 Fixed bug #832: Problem with MARC/charset in yaz-client.
71 Fixed bug #668: save command line history for yaz-client.
73 Fixed bug #830: pkg-config support.
77 Extended ZOOM result set options with two options that may be read by
78 a client: resultSetStatus and presentStatus with values as specified for
80 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
82 Fixed bug #827: Using SSL fails on Debian etch.
84 Fixed bug #826: Weird looking chars for set of MARC records.
86 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
87 that is treated as an ItemOrder with itemRequest being an XML document
88 external. The value of "doc" is the content.
90 Extended the GFS search facility. New member of bend_search_rr
91 'estimated_hit_count' signals that hits is known to be an estmate
92 (higher or lower than real hit count). New member 'partial_resultset'
93 signals that the search was partial (hit count is lower or equal than
94 real hit count). For Z39.50, the information is stored in resultSetStatus
95 member of SearchResponse APDU. For SRU, the information is signalled
96 via SRU diagnostic 59: "Result set created with valid partial results
99 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
101 --- 2.1.46 2007/01/13
103 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
105 Added ZOOM_connection_peek_event.
107 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
108 the following new functions:
109 ZOOM_event_nonblock, ZOOM_connection_process,
110 ZOOM_connection_get_{socket,mask,timeout},
111 ZOOM_connection_fire_event_{timeout,socket}.
112 The existing blocking event handler, ZOOM_event, is a wrapper for the
113 + blocking ZOOM_event_sys_{poll,select}.
115 Implemented function ccl_xml_config which parses XML version of CCL
116 configuration (bug #798).
118 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
120 Added timings utility (yaz/timing.h)
122 --- 2.1.44 2007/01/03
124 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
127 Fixed bug #779: Rotation of apdu.log fails.
129 Fixed for character set conversions:
130 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
131 Honor G1 set in MARC-8 decoding.
133 --- 2.1.42 2006/12/17
135 Fixed bug #775: char conversion does not handle Alternative UTF-8
138 Implemented function yaz_marc_read_line which parses MARC line format
139 records. There is a wealth of formats out there. So far, this function
140 reads line records produced by yaz_marc_write_line.
142 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
143 more generic and easier to remember(!) options: -i format and -o format
144 which specifies input format and output format respectively - where
145 format is one of "marc", "marcxml", "line", "marcxchange".
147 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
148 does not print anything except warnings for records.
150 For yaz-marcdump, added support for MARC split into files (-s) with a given
153 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
154 spec, at http://www.loc.gov/standards/sru/record-update/
155 This has changed the binary layout of the following structs:
156 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
157 bend_update_rr . Patch by Ko van der Sloot.
159 Added GFS utility function bend_assoc_is_alive which returns 1 if
160 association is still alive (client is connected); 0 otherwise (client
161 closed connection). This allows busy servers to stop working for
164 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
165 been a separate piece of software. This version of ziffy has been modified
166 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
168 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
170 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
171 Client code may now interrogate options such as "init_opt_sort" to
172 find out whether the server claims to support various options.
174 --- 2.1.40 2006/11/27
176 Added utilities yaz_{set,get}_esn to set/get element set name from
179 Removed the build of libyazthread.la. The libyaz.so is the threaded version
180 of YAZ and has been so since YAZ 2.1.10.
182 Implemented ZOOM_record_error which returns error information for
183 record (surrogate diagnostic).
185 --- 2.1.38 2006/10/31
187 Updates for SRU Update by Ko van der Sloot:
188 1. Changed name from "operation" to "action"
189 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
190 versions in the code, marked as 'backward compatible'.
191 3. Added diagnostics for SRU Update.
193 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
195 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
197 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
199 For GFS, fixed problem with SRU diagnostic 'First record position out of
200 range' being issued for 0 hits.
202 zoomtst10 part of Windows Build.
204 --- 2.1.36 2006/10/13
206 Implemented yaz_filepath_comp which splits a path into file path
207 components (required by Zebra 2.0.3+).
209 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
210 BSD inspired license until now so this should not have any real impact on
211 anybody. See http://www.opensource.org/licenses/bsd-license.php
213 Fixed bug #687: Missing log lines.
215 Fixed bug #678: CQL to PQF translation does not preserve double-quote
218 Fixed bug #689: SRU diagnostics to be added.
220 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
221 whether a connection is idle (no more work do do).
223 --- 2.1.34 2006/10/04
225 Change type of optval from long to int for invocation of setsockopt with
226 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
228 Added support for specifying the max log file size for the Generic
229 Frontend Server. The size is given with option -r.
231 --- 2.1.32 2006/09/21
233 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
235 --- 2.1.30 2006/09/17
237 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
240 Fixed bug in Generic Frontend Server that could cause a server to stop
241 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
243 For the generic frontend server, the maximum record size is used as maximum
244 size of incoming packages (SRU + Z39.50). The value until was previously
245 only used in Z39.50 Init negotiation and, later, in a session controlled
246 sizes of records returned. This is controlled using -k option. It can be
247 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
249 --- 2.1.28 2006/09/04
251 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
254 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
256 New option for yaz-marcdump -lpos=value which allows setting a portion
257 of MARC header to a certain value.
259 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
261 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
262 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
264 --- 2.1.26 2006/08/15
266 Fixed problem with SRU mode type (soap, get, post) for yaz-client
269 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
271 --- 2.1.24 2006/08/08
273 Fixed MARC ISO2709 encoding routines to deal with character set
276 Minor changes to GFS logging. Database included in search request log
279 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
280 cached/multiple records.
282 Shared libraries are built by default on Unix+configure.
284 Changed cql2pqf transformation to use a different evaluation order. The
285 new order is: always, relation, structure, position, truncation, index
286 and relationModifier. Old order was: always, relation, relationModifier,
287 structure, index, position, truncation. Note that the the latter ones
288 override former ones for identical attributes.. The new scheme means that
289 it is possible to override any existing attribute with a relationModifier.
290 And also that it is possible to override everything for the index rule
291 (except the ones listed in relationModifier). No order is perfect but this
292 one, we believe, covers more real cases.. The "always" should have been
293 called "default", since the attributes there can be overridden with all
296 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
297 compilation phase, but also for yaz-config --cflags output. This allows
298 us to have public headers with Libxml2 stuff in them . It should also,
299 eventually, make Libxml2 checks redundant in packages using YAZ, such
302 --- 2.1.22 2006/06/15
304 Changed SRU update structure bend_update_rr so that SRU diagnostics are
305 stored in uri, message and details.. Previously diagnostics were stored
306 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
307 compatibility.. but he's probably the only one affected, so.
309 Added support for CCL, compiled on the client side, in ZOOM-C. This
310 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
311 input; the resulting query objects can be used for for searching with
312 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
314 YAZ' configure searches for OpenSSL by default.
316 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
317 SL_CTX_use_certificate_file. See
318 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
319 for more info. Thanks to Ko van der Sloot.
321 --- 2.1.20 2006/06/02
323 Bug #600: SRU GET, POST support for yaz-client. Introduced
324 command 'sru' which selects method SOAP/GET/POST.
326 Allow missingValueAction to be specified for the sortspec string -
327 function yaz_sort_spec. By default, the missing value action is null.
328 Use ! to specify "abort". Use = followed by stringvalue to specify default
331 Ensured that Present-handler (if defined) is called in GFS before any call to
332 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
333 searchRetrieve requests.
335 Documentation for YAZ is now based on the Docbook XML/XSLT using
336 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
337 is no longer depending on jade/openjade or docbook-to-man scripts.
338 PDF is no longer part of the distribution - but can optionally be
339 made using DSSSL/jadetex or FOP.
341 Added retrieval handling support in Generic Frontend Server to support
342 conversion between MARC/XML as well as XSLTtransforms. See
343 etc/yazgfs.xml for an example.
345 Added Authentication support to Generic Frontend Server in SRU
346 mode. Authentication using HTTP Basic is supported, as is the use
347 of 'x-username' and 'x-password' parameters in the request itself.
349 Added support for a new character set MARC8s identical to MARC8 except
350 that it converts combined characters to single Unicode characters in the
351 Latin-1 range (when possible).
353 --- 2.1.18 2006/04/24
355 ASN.1 compiler 0.4: generates brief Doxygen file header for
356 generated .h/.c files.
358 Utility yaz_iconv now supports conversion to MARC-8.
360 New facilities for the MARC module. The reading - and writing of
361 content are separate methods for the yaz_marc_t handle. The following
362 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
363 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
364 format). Write functions have prefix yaz_marc_write_.. The existing
365 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
366 available. Removed support for OAI-MARC and simplexml (not the
367 simplexml from PHP5).
369 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
370 to be returned for this connection.
372 --- 2.1.16 2006/03/31
374 Allow multiple languages and charsets to be specified with
375 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
376 negcharset iso-8859-1,utf-8
378 Translation of proximity nodes from CQL into PQF now works.
380 Moved to automake 1.8, 1.9.
382 Added function yaz_log_set_handler which allows a log handler to be
383 installed. This handler will be called for all log messages. Output
384 to file is also produced; but that can be disabled by passing NULL
385 fname to yaz_log_init_file.
387 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
389 For SRW (including GFS), accept application/soap+xml as content-type
392 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
393 produces NO stylesheet reference even if a default stylesheet is specified
396 --- 2.1.14 2006/03/14
398 Updated Windows package to include yazd.dll + yazd.lib for the
399 Development component.
401 If the environment variable YAZ_LOG is set, then it is used as a
402 string indicating the default level of logging to use if not
403 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
404 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
405 used as before. So, for example, to omit warnings from YAZ logging,
408 cql_transform() now map structure and other attributes before indexes,
409 so that index-specific structures and other attributes can override
410 defaults. So now a combination of mapping specifications such as:
412 index.dc.date = 1=date-modified 4=5
413 does the right thing.
415 cql_transform() now also respects the "always" mapping specification,
416 which establishes an initial set of attributes to be used for all
417 terms except where overridden by more specific attributes associated
418 with the index, relation or modifier.
420 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
421 which mode to use; one of "post", "get" or "soap" (SRW, default).
423 Fixes for yaz_iconv routines: changed trie-based character set conversions
424 to use only non-negative values for bit fields due to Sun's C compiler not
425 supporting negative values.
427 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
428 sequences where not read correctly. Fix by Rustam Usmanov.
430 Updated win/makefile to use options, settings which makes things
431 compile with VS C 2005.
433 --- 2.1.12 2006/02/01
435 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
437 In ZOOM socket code, use select instead of poll on MacOSX.
439 ZOOM-C now support client-side compilation of CQL into RPN that is
440 sent to the server, enabling CQL to be used against all Z39.50
441 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
442 ZOOM_query object, and submit it using ZOOM_connection_search().
443 The CQL-to-RPN translation uses a configuration file, the name of
444 which must be specified in the Connection's "cqlfile" option.
446 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
447 function, which takes as its start-term parameter a ZOOM_query object
448 (which may have had either CQL or RPN set into it).
451 --- 2.1.10 2005/11/29
453 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
454 GFS to support this as well. Backend handler, bend_srw_update, does the
455 update work. Code contributed by Ko van der Sloot.
457 Allow retrieval of Search Result-1 information in ZOOM by the use of
458 options that are attached to a result set. ZOOM documentation updated
461 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
462 UTF-8 conversion. Patch by Raj Patel.
464 Added option -m to GFS to control formatting of timestamps in log file.
466 Added 'exit' as synonym for 'quit' in yaz-client
468 Added support for specifying SRW resultSetId + resultSetIdleTime in a
469 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
470 for the new members. Patch by Ko van der Sloot.
472 Added support for SRU POST. It is supported for content-type
473 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
475 Do not build the separate Multi-threaded (MT) library libyazthread.la.
476 Instead make the library libyaz.la multi-threaded. Threading as a whole
477 can still be disabled by configure option --disable-threads. Previosly,
478 with older GLIBCs there were problems with MT libs under Apache. This
479 has now been fixed a long time ago.
481 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
484 CQL module modified to be case insensitive for relations/indexes/operations.
486 Fixed bug in CQL transform code: incorrect value relationModifieder
489 Added 'show all' command for yaz-client which retrieves all results
492 Added new yaz-client, xmles, which takes a (private) OID and
493 a document to be sent as an extended service request.
495 Describe new yaz-client commands wait_response and set_auto_wait.
497 Increase TCP/IP listener backlog from 3 (which I am guessing was
498 copied from the SunOS manual entry way back when) so SOMAXCONN, so
499 that the socket will queue as many incoming connections as it's able
500 to handle ongoing connections. In other words, it will never now
501 refuse a connection that it would be able to handle merely because
502 it's not got around to accepting() enough of the pending connections
503 yet. This is the behaviour anyway under Linux, where the listen()
504 argument is ignored; but not under BSD and on systems such as
505 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
506 YAZ-based servers should now be uniform across operating systems in
509 yaz-marcdump uses 64-bit file access on some systems. This is enabled
510 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
511 This allows yaz-marcdump to read large MARC batches (>2 GB).
513 Modified all YAZ source files - except the source which is auto-generated
514 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
517 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
518 corresponding to the existing *_setl() function. These allow option
519 values containing arbitrary valuues.
521 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
522 ZOOM_resultset_sort() in new applications. Its behaviour is identical
523 except that it returns an indicator of whether or not the sort
524 criterion was accepted (0 for OK, -1 for invalid).
528 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
529 MARC output rather than returning "new" buffer.
531 yaz-client warns about unknown init options.
533 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
537 Added support for SRW sort in Generic Frontend Server. Patch
538 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
539 sortKeys - or NULL if none is provided.
541 Fixed bug #307: It was impossible to specify indefinite/no timeout
542 for ZOOM_event. Special timeout value -1 now means indefinite timeout
545 Added support for multiple languages and charsets to be specified in
546 ZOOM. Each charset/language is separated by a blank. If negotiation is
547 in effect in init-response, Option
548 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
549 Code based on patch by Vasiliy Osadchuk.
551 Fixed bug #306: infinite recursion that occurred when calling
552 yaz_log_level_init as the first call (before other log level or
555 Fixed bug in scan handling in front end server: if preferred-Position-In-
556 Response was non-present, a NULL pointer referece was performed.
560 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
561 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
562 now defined for all those error codes. So instead of putting 109 in
563 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
564 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
566 Modified the yaz-marcdump utility to skip garbage bytes between MARC
569 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
571 Program yaz-client now exits and produces an error message if multiple
572 Z39.50 servers are specified on the command line (none or one allowed
575 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
580 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
582 Fixed bug #272: Preserve spacing for CCL terms.
586 Added support for virtual hosts and multiple backend servers for
587 the YAZ frontend server. The configution is XML based and
588 support specificition of CQL to RPN mappings and explain information.
589 See section "Virtual Hosts" in the YAZ manual.
591 Extended OPAC display utility. OPAC display utility renders
592 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
593 to supplement yaz_marc_decode_wrbuf.
595 Fixed a bug in MARC decoder that could caused it to crash for some
596 invalid MARC records. More diagnostics and warnings where added in
597 XML output (warnings, etc are stored in comments).
599 --- 2.0.34 2005/02/08
601 Fixes for UNIX domain sockets. Bug #261.
603 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
605 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
606 Added yaz_marc_subfield_str which defines subfield lead string which is
607 used in YAZ_MARC_LINE format. Default string is blank+$. Added
608 yaz_marc_endline_str which defines end of fields string used in
609 YAZ_MARC_LINE format. Default string is newline.
611 Experimental support for MarcXChange. This format can be produced
612 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
613 http://www.bs.dk/standards/MarcXchange.xsd
615 Added yaz-client commands scansize that sets maximum number of
616 entries to be returned by scan.
618 --- 2.0.32 2005/01/11
620 Added support for SRW scan in yaz-client and Generic Frontend Server.
622 * Added whereInList member to SRW Scan Term.
624 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
626 Fixed NMEM system to return aligned blocks on the smallest boundaries
627 that are suitably aligned for all possible types on the particular
628 architecture YAZ is being built for.
630 --- 2.0.30 2005/01/04
632 Fixed numerious warnings that was issued with newer versions of GCC.
634 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
635 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
638 Make YAZ Generic Frontend Server slightly faster.
640 Enhance (and reduce) logging for Generic Frontend Server.
642 Revert YAZ log system so that it flushes every write operation
643 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
645 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
646 instead of LOG_, due to name clash with syslog(3). LOG_ are still
647 present. New applications should define YAZ_USE_NEW_LOG=1 - this
648 will effectively disable old definitions.
650 --- 2.0.28 2004/11/09
652 Added yaz_log_time_format which specifies log format using
655 Added yaz_log_module_level which returns mask for a module. Value
656 is non-zero mask a if module is enabled; zero if disabled.
658 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
659 in include/yaz/cql.h.
661 Fixed bug #176: Dont throw diagnostics on empty SRU args.
663 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
665 Fixed bug #172: RPM builds does not enable SSL.
667 Doxyfile.in part of dist. Doxyfile generated by configure.
669 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
670 are given and the corresponding component does not exist.
672 Extend CCL documentation in YAZ reference. Describe r=r.
674 --- 2.0.26 2004/10/01
676 Fixed MARC->MARCXML conversion to properly deal with
677 fields, subfields, indicators having non-ASCII characters.
679 Fixed MARC->MARCXML conversion so that ASCII control characters
680 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
683 Added YAZ GFS support for conversion from Z39.50 surrogate
684 diagnostics to SRW surrogate diagnostics.
686 Bug fix: YAZ GFS did not return schema in explainResponse.
688 --- 2.0.25 2004/09/30
690 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
691 now converts recordSchema to elementSetName as well as schema URI.
693 Fixed bug in COMSTACK that prevented HTTP request packages from being
696 --- 2.0.24 2004/09/29
698 Added CCL facility r=r "range" which is similar to r=o "ordered" but
699 does not require white-space before and after the dash in a range, e.g.
700 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
703 Fixed a few AC_TRY_LINK configure tests that did not operate properly
704 due to new GCC removing "redundant" code.
706 Added yaz-client commands scanpos and scanstep that sets preferred
707 position and step-size for scan.
709 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
711 Added CCL utility ccl_qual_buf which parses one or more CCL
712 spec lines in a buffer.
714 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
715 of name and value - ignoring empty lines and comments.
717 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
719 Added odr_get_element_path which returns current element path for an
720 ODR handle. This utility is useful in error handling or user-defined
723 Added ODR_PRINT utility odr_set_stream which is is a more generic
724 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
725 to a write function and pointer to close function. The close function - if
726 non-NULL - will be called during odr_destroy.
728 Fixed bug in CCL parser where truncation char was not removed from
729 right side when truncation=both was in effect.
731 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
734 --- 2.0.23 2004/08/11
736 Fix buffer overrun in CQL parser when dealing with proximity (%).
738 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
739 to UTF-8/UCS conversion is now only based on codetables.xml.
741 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
743 --- 2.0.22 2004/08/06
745 Add support for more "commit changes" in ZOOM (uses Extended Services).
747 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
750 Yet another small fix for configure of SSL.
752 --- 2.0.21 2004/05/14
754 Fix SSL libs for configure when --with-openssl=DIR is given.
756 --- 2.0.20 2004/05/10
758 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
760 SSL comstack now uses yaz.pem certificate file on server side
761 by default. Certificate filename can be configured by calling
762 comstack function cs_set_ssl_certificate_file before cs_bind is used.
764 Fix bug regarding multiple calls to ZOOM_connection_connect.
766 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
768 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
769 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
771 ZOOM now allows inspection of X509 peer certificate for verification.
772 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
774 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
775 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
776 as "modular" but it simplifies things.
778 Added cs_get_peer_certificate to that returns peer X509 PEM.
780 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
781 NULL if SSL is unavailable.
783 Documentation about MARC decoding tools.
785 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
787 --- 2.0.19 2004/03/30
789 Rename CHANGELOG to NEWS to follow GNU style packing.
791 Fix bug with missing initialization of member in init_diagnostics.
792 This bug affects threaded version of GFS server.
794 --- 2.0.18 2004/03/20
796 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
799 Ensure zlib.dll is packed with Windows install.
801 --- 2.0.17 2004/03/17
803 Fix encoding of xsd:string to use text instead of CDATA.
805 Fix endless loop in CQL parser with unbalanced ".
807 Use a more compact way to store MARC-8 conversion tables.
809 --- 2.0.16 2004/03/16 Debian only
811 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
814 Update CQL parser to use new CQL 1.1 modifiers for booleans and
819 --- 2.0.15 2004/03/01
821 Another fix for decoding of XML packed records.
823 --- 2.0.14 2004/02/25
825 Fixes for Chunked encoding. White space not ignored after length spec.
827 Update NS and use default NS for SRW diagnostic elements.
829 --- 2.0.13 2004/02/23
831 Implement ZOOM_resultset_cache_reset which resets record cache.
833 Implement ZOOM_resultset_sort which sorts a result set.
835 Implement chunked HTTP transfer.
837 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
839 --- 2.0.12 2004/02/16
841 Added member 'schema' to bend_explain_rr structure so that backend
842 can specify explain record identifier. Defaults to Zeerex 2.0.
844 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
846 --- 2.0.11 2004/02/16
848 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
851 Added init command for yaz-client which sends "extra" init request.
853 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
854 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
856 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
858 Make ZOOM error code for "invalid query".
860 Fixed compilation for SSL which wasn't properly enabled for all platforms.
862 --- 2.0.10 2004/02/05
864 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
867 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
869 Added option -p <file> to make Generic Frontend Server to write PID file.
871 Added option -D to put Generic Frontend Server in background on its own.
873 Make ZOOM C recognize option "password". If unset, "pass" is used
874 (for backwards compatibility).
876 Fixed a bug in Generic Frontend Server that could make it crash if a
877 client sets characterSetNegotation bit, but didn't pass negotiation stuff
880 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
881 Must be issued before open, in order to be in effect.
883 --- 2.0.9-6 2004/01/12 Debian/Windows
885 Make the SRU server more picky WRT unknown params, etc.
887 Bug fix: ZOOM scan response didn't return displayTerm - when present.
889 New YAZ client command, options, that sets Z39.50 options.
891 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
892 options from a string of tokens (one token for each option bit).
894 Update SRW diagnostic code messages.
896 --- 2.0.9-5 2004/01/07 Debian/Windows
898 Handle user defined stylesheet for SRW/SRU.
900 --- 2.0.9-4 2004/01/06 Debian/Windows
902 Fix bug in decoding of Content-Length.
904 --- 2.0.9-3 2004/01/06 Debian/Windows
906 Fix a bug with decoding of XML packed records.
908 --- 2.0.9-2 2004/01/05 Debian only
910 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
912 Fix bug in SRW/SRU diagnostics decoding.
916 Fixed bug in Generic Frontend Server which could drop records exceeding
917 preferred message size. Reported and fixed by Irina Dijour.
919 Fixed calculation of package size for structured records in Generic
920 Frontend Server. Reported and fixed by Irina Dijour.
922 Fixed namespace for SRW/SRU diagnostics.
924 Fixed SEGV in yaz-client that occured for HTTP connection errors.
928 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
929 this version is incompatible with version 1.0 and older YAZ SRW/SRU
932 CQL changes to reflect recent changes to the specification:
933 * Documentation talks about context sets instead of index sets.
934 * Documentation talks about indexes instead of qualifiers.
935 * The CQL-to-PQF transformer's configuration file now uses
936 "index.set.name = <attributes>" instead of the old form
937 "qualifier.set.name = <attributes>". (Both forms are still
938 understood but the latter is deprecated.)
939 * CQL terms with no explicit index specified are now interpreted as
940 cql.serverChoice instead of srw.serverChoice (which of course
941 behaves exactly the same.)
945 MARC conversion can now generate ISO2709 output in another
946 character set. yaz-marcdump uses this facility if you invoke it
949 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
950 functions from there can be used from C++.
954 Frontend server now transfers memory from decoded packages to stream
957 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
958 references to show up.
960 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
961 the ZOOM Abstract API. The older names for the same options are still
962 also supported for the benefit of old applications.
964 ZOOM-C supports "implementationId" and "implementationVersion" options
965 to go along with "implementationName". These allow the user code to
966 specify identification strings to be sent to servers.
967 Add OID for the new ExtLite attribute set.
969 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
970 as requested/supplid by Ere Maijala <ere@atp.fi>
972 For generic frontend server, reverse the order of
973 "toolkit-supplied / application-supplied" strings sent as implementationId,
974 Name and Version. Also, remove the spaces around the slash. This brings
975 the GFS in line with the behaviour of ZOOM-C on the client side.
977 Add function ZOOM_scanset_display_term.
979 yaz-client shows scan displayTerm if present.
981 Utility yaz-iconv is now installed by default along with the man page
984 Extend configure check for OpenSSL to use pkg-config where available (such
987 Incorporate patch by Morten Bogeskov which allows a Unix file socket
988 server to specify uid/gid/mask for socket using the format
989 unix:[user=uid,][group=gid,][umask=mask,]file=path
990 If file= is omitted the existing format is assumed, e.g.
992 in which case the mask is 0666 (rw for everybody).
994 Major restructure of YAZ source. All source in libyaz is in src directory.
995 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
996 util (utility programs such as ASN.1 compiler, yaz-marcdump).
998 Added man page for utility yaz-marcdump (used to be called marcdump).
999 yaz-marcdump is installed by 'make install'.
1001 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1002 of incoming package failed.
1004 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1006 Change prototype of odr_perror: add const to message string.
1008 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1010 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1011 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1012 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1013 DNS lookup. There should not be any compatibility problems with this
1014 assuming that blocking=1 or 0 is used.
1016 Fix bad reference in UNIX comstack in function cs_addrstr.
1018 Fix for compilation on AIX.
1020 The generic front-end server (server/seshigh.c) now supports returning
1021 Init diagnostics to the client in User-information-field, in
1022 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1025 --- 2.0.4 2003/09/04
1027 Allow any CQL relation (not just all,any,exact,scr).
1029 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1030 that features the same UI.
1032 Implemented command update0 in YAZ client which is equivalent to
1033 update but uses old of Ext Update ASN.1.
1035 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1036 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1037 Previously no OID was used for this info.
1039 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1040 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1041 returns 'malformed search term' otherwise.
1043 SortResponse member resultCount now set to NULL in sort handler of
1046 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1049 Add three new utility functions for translating OIDs between various
1050 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1051 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1052 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1053 char *oid_to_dotstring(const int *oid, char *oidbuf);
1054 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1056 Reverted modifications for ES Update definition for z_IU0Update
1057 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1058 is back to YAZ 2.0.2.
1060 String value attributes for CCL parser.
1062 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1063 which their FirstSearch server returns in Init responses, sometimes
1064 carrying useful diagnostic information when Init fails. This has the
1065 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1066 "z39.50/oclcui.asn", where its definition is somewhat different from
1067 what OCLC document on their web-site, as required to interoperate with
1070 Support for anonymous authentication in yaz-client. Use the command
1073 * Fix the OID of the Index Data-local "admin" Extended Service from
1074 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1075 the 1000, which indicates a locally-defined OID, was a mistake.
1077 --- 2.0.3 2003/06/20
1079 Fix CCL directive @case handling so that it affects string match for
1080 both CCL keywords and qualifiers.
1082 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1083 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1084 Decoder has been updated with ASN.1 changes as listed in
1085 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1086 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1087 z_IUUpdate, remains unchanged.
1089 ZOOM_record_get may now return a record in a specific character set.
1090 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1091 "from" is the character set of record as returned by target. "to" is
1092 the character set to be returned. If omitted, "to" is UTF-8.
1094 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1096 New ODR utility, odr_getelement, which returns name of element for
1097 which encoding/decoding failed.
1099 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1100 in cases where a required element was omitted.
1102 Bug fix: some MARC8 sequences were not converted.
1104 New ZOOM option "step" which specifies number of records to be
1105 retrieved in one chunk. Used in conjunction with "start" and "count".
1107 SRW support for yaz-client. Use scheme http: to use it, e.g.
1110 yaz-client no longer does (un)intelligent character set conversions
1111 by default. Can be enabled with charset and marc_charset commands.
1113 xmalloc trace fix for 64-bit systems such as DEC alpha.
1115 Solaris 2.6 compile fix.
1117 New function, cql_strerror() translates SRW error codes, as returned
1118 by cql_transform_error(), into human-readable English strings. Used
1119 in yaz-client diagnostics when appropriate.
1121 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1122 converts it into a type-1 query which is sent to the server. This
1123 makes CQL available for use with all Z-servers, as opposed to the tiny
1124 minority that can handle CQL queries themselves.
1126 --- 2.0.2 2003/04/28
1128 New Debian package layout similar to the Redhat Package layout.
1130 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1131 and search result respectively.
1133 --- 2.0.1 2003/04/25
1135 Redhat package is now several packages: libyaz (runtime libraries),
1136 libyaz-devel (development and documentation, and yaz (utility programs).
1137 Package spec file by Morten Bøgeskov.
1139 New member 'schema' in struct bend_fetch_rr which the name of requested
1140 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1141 handler MAY set this to reflect the schema of the returned record.
1143 New member 'display_term' in struct scan_entry. GFS now sets member entries
1144 and allocates scan entries to be filled by user scan handler. In previous
1145 version, entries member was allocated by the scan handler. That still works,
1146 but the GFS will ignore member display_term - assuming it was NOT set by
1147 the handler. The fact that the GFS now allocates the entries both allows
1148 for new members and makes a scan handler easier to write.
1150 Fix CQL lex buffer overflow.
1152 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1153 SRU default recordPacking is string.
1155 SRU protocol support for frontend server.
1157 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1159 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1161 Added scan for the ZOOM shell (zoomsh).
1165 * String Identifers for Schemas (Amendment 5).
1166 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1167 Old definition for schema
1168 Odr_oid *schema; /* OPT */
1173 Z_InternationalString *uri;
1174 #define Z_Schema_oid 1
1175 #define Z_Schema_uri 2
1178 * resultCount parameter to Sort Response (Amendment 1).
1179 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1181 Support for SRW 1.0 over HTTP. This is an optional feature and
1182 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1185 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1186 on the same port. SRW SearchRetrieveRequests are mapped
1187 to bend_init,bend_search,bend_fetch,bend_close.
1189 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1191 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1192 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1194 ZOOM connections are SRW based if schem http is used for hostname
1195 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1196 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1198 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1199 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1200 distance=n, order=true/false, relation=le, prox unit=word. If
1201 n is omitted, distance 1 is used.
1203 Fixed problem with C compiler include path in wrong order.
1205 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1206 on Solaris. Patch from Ko van der Sloot.
1208 New MARC decode API. All new functions operate on a yaz_marc_t
1209 handle. The most important new functions are: yaz_marc_create,
1210 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1211 decode and destroy respectively. Decoder can produce formats
1212 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1213 include/yaz/marcdisp.h.
1215 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1216 to UTF-8, UCS-32, wchar_t or Latin-1.
1218 * Prototypes for yaz_iconv_-functions moved to separate header
1219 include/yaz/yaz-iconv.h.
1221 Make a few private functions 'static' in unix.c. This prevents
1222 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1224 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1225 are set when Init Response is received.
1227 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1228 but returns diagnostic set as well.
1230 New function yaz_strerror which is a portable wrapper for
1231 strerror/strerror_r/GetLastMessage.
1233 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1234 is returned for MARC. If type is "oai", then OAI MARC is returned.
1236 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1239 --- 1.9.2 2002/11/26
1241 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1243 Fix bad race conditions on SIGTERM and terminate gracefully in
1246 Move retrieval (data1) module to Zebra since nobody seems to be
1249 Add GRS-1 render for ZOOM using same format as yaz-client.
1251 --- 1.9.1 2002/10/05
1253 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1255 Fix broken ESpec handling in data1 module.
1257 SGML reader parses comments and makes them part of the data1 tree.
1259 Added several type casts so that YAZ compiles as C++ code.
1261 ZOOM didn't handle PDU encoding failures properly.
1263 Added more Bib-1 diagnostics (approved extensions).
1265 GNU configure: better check for iconv.
1267 More portable use of accept, getpeername. Check for socklen_t. Use
1268 int/size_t if socklen_t is not defined.
1272 PQF parser rejects bad queries - including those with extra
1273 characters in them. PQF parser used to silently ignore that.
1274 Cleaner API for PQF added, which allows you to get detailed
1275 error information for bad queries (see yaz/pquery.h).
1277 Fixed bug in ZOOM_record_get for type "database".
1279 Implemented mini iconv library supporting conversions between
1280 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1282 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1284 --- 1.8.9 2002/08/20
1286 Fixed ZOOM C record cache so that preferredRecordSyntax and
1287 elementSetName is used to check for already fetched records.
1289 --- 1.8.8 2002/08/02
1291 Added three members in bend_initrequest structure to facilitate
1292 character set negotiation.
1294 Fixed a bug in frontend server that could cause indefinite
1295 loops under rare conditions.
1297 Revised character set utilities (charneg.h) so that encoding
1298 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1300 For PQF, directive @term <type> sets term type for Scan/Search.
1301 Here <type> is general, string, numeric, null. The term type
1302 is inherited - just like @attr.
1304 New call odr_set_charset that sets character set conversion for
1305 international-strings on a ODR stream. Prototype is:
1306 int odr_set_charset(ODR o, const char *to, const char *from);
1307 The InternationalString is still represented as C string in YAZ
1308 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1309 won't). On the protocol level, you can use any encoding.
1311 Support for UNIX sockets in ZOOM.
1313 Solaris recv sometimes returns errno == ENOENT. It is treated as
1314 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1316 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1317 both client and server. Code by Morten Bøgeskov.
1319 --- 1.8.7 2002/05/22
1321 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1322 that they can be used directly from Visual Basic. You must recompile
1323 your windows APP if you're using ZOOM.
1325 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1326 Commands "lang" and "charset" sets language and character set respectively.
1327 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1328 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1330 Attributes from multiple CCL fields may be OR'ed rather than merged
1331 using directive "@field or". Fields are still merged by default -
1332 equivalent to "@field merge".
1334 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1337 Fixed bug in zget for parameter ExtendedServicesResponse.
1341 --- 1.8.6 2002/03/25
1343 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1345 Client displays USR.1:SearchResult-1 (hits per term).
1347 Additional Search Info for search in Generic Frontend Server.
1349 Fixed CCL parsing of "field=s".
1351 WIN32 installer - using the excellent NSIS software from nullsoft.
1353 Fixed CCL parsing of "field = - <number>".
1355 Added function yaz_marc_decode that decodes MARC for line mode
1356 display or XML (similar to that used by JZKit).
1358 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1359 Z39.50. But ISO/ILL was, however.
1361 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1362 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1365 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1367 --- 1.8.5 2002/02/03
1369 New YAZ client features: Command completion and new commands:
1370 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1371 Code provided by Jacob Poulsen.
1373 New call oid_trav, that visits all registered OIDs via callback.
1375 Function ZOOM_record_get now returns const char pointer rather than
1376 void pointer. It saves a lot of type casts.
1378 For YAZ client, command "auth" now allows you to set authentication
1379 in IdPass style. It is enabled when three tokens are given - order
1380 is user, group and password.
1382 Fix memory leaks in MARC record handling for ZOOM.
1384 New option for YAZ client, -k <kilobytes> that sets
1385 maximum record size. Similar to -k option for generic frontend
1386 server and yaz-ztest.
1388 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1390 Prefix query parser reports "fail" when bad attribute set is given.
1392 Fix in MARC decoder. Proximity logging. Fix for attribute set
1393 in scan handler for server. Patches by Shigeru Ishida.
1395 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1398 Configure option --with-openssl=<dir> now works when a directory is
1399 specified. Patch provided by Morten Bøgeskov.
1401 New option for YAZ client, -u <auth>, that sets authentication.
1403 ZOOM fix: error information was sometimes "missing", since error
1404 was cleared/reset too when it shouldn't.
1406 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1408 --- 1.8.4 2002/01/04
1410 Scan for ZOOM API. New object ZOOM_scanset. New functions
1411 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1412 ZOOM_scanset_destroy.
1414 New ZOOM function, ZOOM_connection_last_event, that returns type
1415 of last event (such as "receive data", "send data", "apdu received",
1418 New ZOOM option, schema, that specifies schema for retrieval.
1420 New CCL feature. Qualifiers can be aliases for one or more
1421 other qualifiers (if more than one is given, OR is used).
1423 ZOOM uses named result sets if target supports it.
1425 Two new YAZ client commands: . (dot, which sources a script of YAZ
1426 client commands), and ! (to execute shell command.). Implemented
1429 Working on Debian packages.
1431 --- 1.8.3 2001/11/19
1433 YAZ client enables named result sets only if target supports it.
1435 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1437 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1438 with key="host" to get same result.
1440 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1441 Function Z3950_resultset_record(s) returns references to records
1442 "owned" by resultset. To become owner use Z3950_record_clone.
1444 Function z_ext_record handles Extended Services. Thanks to
1447 --- 1.8.2 2001/11/12
1449 CCL Parser fix: ignore token comma when dealing with and-lists.
1451 Documentation updates for COMSTACK.
1453 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1454 Changed prototype Z3950_records. For some functions, int parameters
1455 were changed to size_t.
1457 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1460 New MARC decode/display function, marc_display_exl, which properly rejects
1461 non-ISO2709 records. YAZ client uses it.
1463 --- 1.8.1 2001/10/29
1465 Fix bug: local attribute set wasn't set correctly in PQF strings.
1469 * Old Z39.50 codecs no longer supported.
1471 Added ZOOM C binding. See http://zoom.z3950.org/
1473 Renamed states for COMSTACKs to avoid confusion with events.
1475 Implemented cs_look and proper cs_rcvconnect.
1477 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1479 Configure detects POSIX threads on OpenBSD.
1481 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1482 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1484 When error is returned from present handler, non-surrogate diagnostic
1485 is returned in present response (and fetch handler is no longer called).
1487 * Minor adjustments to pquery parser (PQF). Token characters may be
1488 escaped by using backslash (C-style).
1490 PQF parser allows string attribute values to be specified. For @attr,
1491 non-numeric characters after the equal-sign are treated as strings
1492 (e.g. @attr 9=title).
1494 CCL trunction character may be defined (@truncation in file)
1496 * function zget_ExtendedServicesRequest sets waitAction to
1497 waitIfPossible (was wait).
1499 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1502 CCL operator names may be set in field definition files (CCL_bibset).
1503 See ccl/bib1 for an example.
1505 Fixes in ASN.1 compiler for C++ compatibility.
1507 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1508 and "op_or" to avoid conflict with C++.
1510 Fixed problem with GNU readline detection on Redhat 7.0.
1512 Added step-size for Scan backend handler.
1514 Fixed bug that made the frontend server crash when no attribute
1515 set was specified for scan.
1517 Front-end server automatically switches to original working directory
1518 when installed as an NT service. Previously -w had to be specified to
1521 Added extended attributes for retrieval module (data1), so that data1
1522 records carry d1_readXML/SGML attributes. d1_read also supports
1523 null-data rules ( <tag/>)
1525 On UNIX when POSIX threads are available, a separate library libyazthread
1526 is created. Programmers should link with that library and the yaz library
1527 when using threads. The reason for the split was that some applications
1528 on Linux, such as Apache, doesn't work well when using shared objects that
1531 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1532 (or any frontend server) in SSL mode by specifying ssl: followed by
1533 address. Only tested on UNIX.
1535 Added feature for CCL module. Virtual structure s=al or s=ol generates
1536 and-list and or-list respectively instead of phrase search.
1540 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1541 log_mask_str. This was done to avoid name conflicts with other libraries
1542 (such as other PHP extensions).
1544 Added raw OID member for preferred record syntax (request_format_raw)
1545 and returned record syntax (output_format_raw) for backend fetch method.
1547 Config file yaz-config now accepts options so that it returns specific
1548 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1550 Shared library support for UNIX using GNU libtool.
1552 * Modified backend interface. Request/Response struct's replaced by
1553 one read/write C struct. For example bend_fetchrequest and
1554 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1555 Every handler - even search has to be registered in bend_init
1556 handler. This means that the YAZ library no longer refers to
1557 external functions and it makes it possible to make the whole
1558 thing a single DLL/SO.
1560 Added Segment handler for backend server.
1562 Added Zmbol/Zebra administrative functions to YAZ client.
1564 Threaded frontend server on UNIX (when POSIX Threads are available).
1565 Starting the server with option -T enables multi-threading.
1569 Added configure option --enable-comp/disable-comp to control use
1570 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1571 located in sub directory asn.
1573 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1574 in ${exec_prefix}/bin along with the other programs yaz-client and
1577 GNU automake used to maintain makefiles.
1579 Added several OID's.
1581 Changed retrieval module so that we can load records with no abstract
1582 syntax defined. Tagpaths in these records are fully composed of string
1585 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1589 On UNIX, the generated makefile now supports a proper 'make install'.
1590 The prefix can be set via GNU configure to set the install location
1591 (default is /usr/local).
1593 * YAZ programs client and ztest were renamed to yaz-client and
1594 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1595 locations, such as /usr/bin,/usr/local/bin,etc.
1597 * YAZ Header files were moved from include to include/yaz. YAZ Header
1598 files are referred to as include <yaz/log.h> rather than <log.h>.
1599 The YAZ include path (-I ..) is therefore the same as before. Programmers
1600 should update their #include statements or use -Ipath/include/yaz
1601 instead. The main motivation for doing this change is that YAZ header files
1602 can be installed in "standard" locations /usr/include,/usr/local/include
1603 without introducing conflicts, since ALL YAZ header files are stored
1604 in subdirectory yaz (under /usr/include for example).
1606 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1607 rather than project/workspace files. We switched because project files
1608 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1611 Changed name of logging function, logf, to yaz_log, to prevent name
1612 clash with some math-log functions. The YAZ header log.h defines logf
1613 to yaz_log (#define) so there should be no incompatibilities by this
1616 Added bend_start/bend_stop handlers for server. These handler are
1617 called on start/stop of server. For windows they are called whenever
1618 a service is started/stopped.
1620 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1621 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1622 in util/yc.tcl. The auto-generated C code structures are, in a few
1623 cases, incompatible with the old decoders. There are differences in the
1624 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1625 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1626 The preprocessor variable ASN_COMPILED is defined when the compiled
1627 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1628 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1629 wish to use the old encoders/decoders you can specify --disable-yc
1632 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1633 version so that it supports both new - and old version of DB Update
1635 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1636 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1637 change. The name parameter can be set to 0 in which no name is specified
1638 for the construction. The macros odr_implicit and odr_explicit sets name
1639 parameter to zero for the construction involved. New macros
1640 odr_implicit_tag and odr_explicit_tag are similar to the others,
1641 except that a name parameter is added. For programmers' that don't use
1642 ODR they probably only need to change the call to z_APDU and z_External.
1644 Added access control facility by interfacing the TCP wrapper library.
1645 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1646 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1647 name of the daemon and enables the access control as specified in
1648 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1650 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1651 den Dool <H.M.vdnDool@kub.nl>.
1653 Added reference ID parameter to most functions in server API - refer
1654 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1656 Changed name of ccl library to libccl.a (was ccl.a).
1658 Fixed bug in decoder for Explain (Category TargetInfo).
1660 Added support for GNU readline in client. Thanks to Jacob Poulsen
1661 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1663 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1664 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1665 IMPLEMENTATION! This change was made to the development version before
1666 the ZIG decided to retract the amendment. If any users MUST be
1667 compatible with the original Update definition, PLEASE CONTACT US, and
1668 we will include a separate definition corresponding to the old Update
1669 ES. Note that because of the change to the ASN.1 of the
1670 TaskPackageRecordStructure we cannot define a single structure that
1671 will support both versions.
1673 * Added const modifier to buffer parameter for some ODR/BER encoding
1674 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1675 completeWAIS, odr_dumpBER.
1677 Fixed bug in client.c which caused a crash when a scanResponse didn't
1678 contain positionOfTerm.
1680 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1681 * will cause an error in a client if a non-YAZ target sends both a
1682 * list of Scan entries and non-surrogate diagnostics.
1684 Retrieval module enhancements. Tag sets may be typed in the reference
1685 to it. From the .abs-file the "tagset" directive takes a third optional
1686 integer type for the tag set referenced. From a .tag-file the "include"
1687 directive takes a third optional type as well. The old "type" directive
1688 in the tag set itself is still recognized but acts as the default type
1691 Backend interface change. Individual Scan terms returned from bend_scan
1692 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1693 in include/backend.h.
1695 Retrieval module enhancements. Multiple tag sets and attribute sets may
1696 be specified in abstract syntax specs. Revised the error/warning for
1697 logging messages reported by the retrieval module when reading the
1700 Object Identifier system (oid_..) changed. The API is backwards
1701 compatible but the oid-routines now allocates new OID's when needed.
1702 Raw OID's may be specified in oid_getvalbyname.
1704 YAZ now uses GNU configure to generate Makefile(s).
1706 * Minor changes in some of the member names of DeleteResultSetRequest and
1707 DeleteResultSetResponse. See include/proto.h.
1709 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1710 and added member 'languages' in TargetInfo (which was missing).
1712 Changed the way attribute sets are handled in the retrieval
1713 module. These are now cached, just like the abstract syntaxes
1716 Changed YAZ so that it links with compiled ASN.1.
1718 Added Explain-schema definitions and mapping routines. The following
1719 Explain categories have been implemented: AttributeDetails,
1720 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1722 Fixed minor bug in Windows version of Server Library.
1724 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1726 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1728 Added EXTERNAL: UNIverse Resource Report (non-standard).
1730 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1731 ENUMERATED and SET OF.
1733 * Added 'const' to some of the char pointer arguments for the
1734 functions, data1_read_node, data1_getelementbytagname,
1735 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1738 Fixed bug in data1_insert_taggeddata - the last_child member of
1739 parent wasn't initialised.
1741 * Changed data1_read_record and data1_read_node so that the supplied
1742 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1743 doesn't refer to any parts of the "SGML"-buffer.
1745 Fixed bug in server library (Windows version of statserv_remove).
1747 * Changed code so that it compiles as C++. The type definition
1748 of Odr_fun which is a member of Odr_arm was changed. The result is,
1749 that an explicit typecast is needed for the fun pointer when
1750 using Odr_arm - as in:
1751 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1753 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1755 Implemented the new structured date and time definition as approved
1756 by the ZIG. Added schemaId element to the specificTag in Espec-1
1757 (also approved at the last ZIG). Thanks to RVDM.
1759 Added some Object identifiers (RVDM).
1761 Changed the Update Extended Service (RVDM).
1763 Added command "refid" to client which specifies referenceId for
1764 the following requests.
1766 Implemented extended service handling for server. See ztest.c
1767 for an example as well as backend.h. New handlers are registerd
1768 in the Init handler.
1770 * Changed interface for sort in server.
1772 Added new members to statserv_options_block. It allows a server
1773 to read options from another source than just the command line. Thanks
1774 to Charles Woodfield.
1776 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1777 renamed to zboolean. Some C++ compilers complained about the name.
1779 Minor changes to gils.abs. Added index 's' (sort) on title
1780 and date/time-last-modified.
1782 --- 1.4pl2 1998/1/30
1784 Fixed bug in server library regarding inetd mode (-i). This bug
1785 was introduced by release 1.4.
1787 --- 1.4pl1 1998/1/29
1789 Added sort facility in client and backend server interface.
1791 Fixed problem with dependencies in Makefile(s).
1793 Fixed bugs for encoders/decoders of extended services and
1796 Implemented sub-tree feature for schemas. Sub-trees are
1797 referenced in *.abs-files. See explain.abs for an example
1798 of the use of this feature.
1800 Modified bib1.att; local attributes for ANY didn't include
1801 ANY itself (only affects use of the retrieval module).
1803 Fixed bug in plain SGML reader in function data1_read_node:
1804 tags with prefix "var" was incorrectly interpreted as variants.
1806 Added feature "sub-schemas" to enable references to - and definitions
1807 of - group of elements.
1809 * Removed member parent from type data1_element (in data1.h).
1811 Implemented function odr_nullval() that returns the value of
1814 * Removed member num_children from data1_node (in data1.h).
1816 Made NT service interface part of the server library. The
1817 function statserv_main uses the NT service when required and
1818 calls the statserv_start / statserv_close routines.
1820 Routine zget_SearchRequest and zget_PresentRequest fills
1821 resultSetName/Id member with "default" instead of "Default".
1823 Fixed memory leak in server. Request queue member wasn't freed.
1825 Fixed nmem_exit so that memory is freed.
1829 Revised the CCL parser utility to be thread safe.
1831 Added function, oid_ent_to_oid, to replace the function
1832 oid_getoidbyent, which is not thread safe.
1834 * Added nmem_init and nmem_exit to initialize and release
1835 NMEM resources. Function nmem_init should be called once in the
1836 initial thread before NMEM/ODR is used. statserv.c and client.c
1837 have been changed accordingly. The change was necessary to make
1838 NMEM thread safe. The NMEM memory pool is shared amongst threads
1839 in a process. Unix-based applications will still work fine without
1842 Added NT Services interface for the the Z39.50 (statserv) Server.
1843 Refer to the ztest.c source on the usage.
1845 Windows 95/NT port using MSVC5.0. Project files are included in the
1848 * Defined new 'global' handle for the retrieval (data1) system. The
1849 new handled, data1_handle, describes the state of the data1 system.
1850 This handle is passed as first argument to virtually all
1851 data1 related routines. The functions data1_create and data1_destroy
1852 creates and destroys a data1 handle respectively.
1854 Added ODR encode stream member to all backend request structures
1855 init, search, scan etc. This stream should be used to allocate all
1856 memory used for the response when thread safe operation is needed.
1858 Changed the comstack utility, cs_addstr, to be thread safe. The
1859 returned hostname string returned by the function is now part the
1862 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1863 function. The cs_straddr takes a COMSTACK handle as argument, so this
1864 function must be used after cs_create and before bind/connect.
1865 This function is thread safe.
1867 Moved test server to 'ztest' directory - generic server code still
1868 in 'server' directory.
1870 Made prefix query (pquery.c) utility thread safe.
1872 Added new function modifier YAZ_EXPORT to 'export' public DLL
1873 functions when using windows (see include/yconfig.h).
1875 Added definitions to the OID database (util/oid.c) (RVDM).
1877 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1879 Added call to ccl_rpn_delete in client program.
1881 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1882 release of RPN structure.
1884 Added support for C++, headers uses extern "C" for public definitions.
1885 With input from RVDM.
1887 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1888 Thanks to Ronald van der Meer (RVDM).
1890 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1892 Added support for private extensions to the OID database
1893 (oid_setprivateoids()). Thanks to RVDM.
1895 Added optional, physical ANY (key replication)
1897 Fixed null-reference problem in GRS-1 output filter.
1899 Proximity operator added to Prefix Query Format (PQF).
1901 In test client command "base" accepts multiple databases.
1903 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1907 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1909 Smallish bug-fixes in the new encoders/decoders (explain).
1911 Bug fixed in DeleteRequest.
1913 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1915 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1917 Added SOIF syntax (using private OID for now) to retrieval module and client.
1919 Added Update extended service.
1921 Added SearchResult-1 additional info structure.
1923 Added optional CCL (ISO8777) interpreter as separate module. Available
1926 --- 1.2 1996/6/10 (1st anniversary release)
1928 Added Summary record syntax. Lightly tested.
1930 Added OPAC record syntax. Untested.
1932 Added ResourceReport service encoders/decoders. Untested.
1934 Fixed bug in z_Unit - wrong tagging on unitSystem.
1936 Fixed bug in the DiagRecs decoder.
1938 Added options for max PDU size and session timeout to frontend-server.
1940 Added documentation of query-language parsers and other supporting utilities.
1942 [frontend-server] Added Attribute set to the bend_scanrequest API.
1944 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1945 surrogate diagnostics were generated.
1947 [retrieval] Allow multiple local values for attribute.
1949 [retrieval] Allow multiple attributes per element in .abs files. index type.
1951 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1953 --- 1.1pl2 1996/4/10
1955 Minor changes, mostly specific to Zebra's requirements (retrieval)
1959 Repaired bug in frontend server when running multiple listening
1960 endpoints in dynamic mode.
1962 z_External() now won't break if a known, ASN.1 value comes encapsulated
1963 in an octet-string. The value will pass through unmodified in an Odr_oct.
1965 Added a bit of code to the demo client to decode & display
1966 ASN.1-structured records represented in the octet-aligned branch of
1967 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1969 Added z_ext_getentbyref() to the ASN module. Doc updated.
1971 * Completed the SCAN definition in the ASN module. This may break SCAN
1972 code based on older YAZ-versions at compile-time. The fix is easy -
1975 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1976 under the SCAN definition. Remember to initialize this, server-people.
1978 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1979 that this does not extend to ODR and ASN.
1981 Comstack allows insertion of established socket (primarily for
1982 inetd-operation of servers). Doc updated.
1984 Front-end server can now start from the inetd in TCP mode. Doc
1987 --- 1.0pl4 1996/1/24
1991 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1992 the rank and record number.
1994 Adjustments to the frontend server.
1996 Fixed diagnostic BER dumper. It ignored the file argument.
2000 Various changes to retrieval module.
2002 Changed the union discriminators of the protocol files from enums to
2003 ints paired with #defines.
2005 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2008 *Changed operator in the RPN structure to 'roperator', again to avoid a
2011 Fixed problems in Explain decoders/encoders.
2013 --- 1.0pl2 1995/12/6
2015 Memory bug in log module fixed.
2017 --- 1.0pl1 1995/12/5
2019 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2021 Bug in Explain DatabaseInfo module fixed.
2023 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2027 The shift to v1.0 signals that we now consider the *core* functionality
2028 of YAZ reasonably stable (the core being more or less equivalent to
2029 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2030 tested (Explain not at all - though that will happen soonish).
2032 Minor changes to code to support Windows port.
2034 Various minor changes after we're getting to use GRS-1 & co. more.
2036 Added Espec-1 format.
2038 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2039 of the protocol and it cannot be selected when encoding (maps into 'string'
2040 when decoding). Needed to talk to some servers.
2042 Demo client can request simple element set names.
2044 Added Diagnostic Format encoders/decoders.
2046 Added simple Close handling to frontend server (no hooks for resource
2047 reporting yet), and demonstration client.
2049 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2051 --- 1.0b3 1995/08/24
2053 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2054 handled incorrectly when records were requested in the searchResponse. This
2055 will only affect you if you use the frontend-server.
2057 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2058 Test-client will ask for and print GRS1. Ztest will return dummy records
2061 Added Explain encoders/decoders to the service-level API. Untested.
2063 Added Extended Services: Item Order encoders and decoders to the Service-
2064 level API. Untested. We could use a recent copy of the pertinent bits
2065 of the ILL protocol to add those bits.
2067 Added diagnostic format 1 encoders/decoders to the service-level API.
2070 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2071 odr_cons.c, which causes a more correct output.
2073 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2074 was always set to 0 when no records were requested in the searchRequest.
2076 * Added better external-handling. This shouldn't harm old code that
2077 *encodes* externals. It can break code that looks for a
2078 'single-ASN1-type' representation, since those types that are known
2079 are now decoded immediately. Look at the SUTRS sample code in
2080 seshigh.c and client.c. Documentation updated.
2082 Handling of structured records in bend_fetchresponse. Length -1 marks
2083 structured record, type is deduced from format field.
2085 --- 1.0b2 1995/06/27
2086 Fairly quick maintenance release to add SUTRS support.
2088 Fixed handling of SUTRS records in the demonstration client.
2090 * Added format field to the bend_fetchrequest and bend_fetchresponce
2091 structures of the backend API (frontend server). When the record is
2092 returned, the value of the format field is mapped to an OID. The
2093 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2094 of the record. The special value VAL_NONE in the bend_request means
2095 that no specific format was requested by the client. Documentation
2096 updated accordingly. Test server (ztest) will return a fixed dummy
2097 SUTRS record if your client requests SUTRS.
2099 Documentation updated accordingly.
2101 You can now set external libraries and RANLIB support in the top-level
2105 First public release.
