1 Change to emit_term() in CQL-to-PQF query translation: when a term has
2 the /regexp relation modifier, do not process it for leading and
3 trailing "^" and "*", which have quite different meanings in regular
6 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
7 write handlers no longer carries a 'last' parameter. This will make
8 yaz_iconv flush "less" characters. A flush is performed by call to
9 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
11 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
12 removed, because function yaz_query_to_wrbuf does the same.
14 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
15 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
17 Deprecated MARC utility functions removed.
19 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
22 Branch split: YAZ_2_1_55_branch
26 Fix to ZOOM-C so that transparent reconnection is properly handled on
27 connections that are in asynchronous mode.
29 Fixed compilation on OpenBSD 4.0.
31 Large strings in GRS-1 records are now properly displayed in yaz-client.
33 Added character conversion support for "advancegreek"; based on patch from
36 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
37 sequence is met. Before the error was not set so it would be unknown.
39 Adjust yaz-marcdump MARC reader so that it skips until record separator
44 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
45 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
46 fd_set structure used as a bitmask for the FDs to be selected on.
48 Using ACX_PTHREAD macro to check for POSIX threads.
50 Fixed have-vsnprintf check.
54 Fixes for configure on BSD. Bug #900.
56 Added snprintf/vsnprintf wrappers for systems that don't have
57 limits (heavens forbid).
59 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
60 created before all previous tasks were completed and removed from the
61 task queue, the new task could be removed by a mistake.
63 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
65 Implemented pass-through CQL-to-PQF conversions. Bug #861.
67 Fixed bug #832: Problem with MARC/charset in yaz-client.
69 Fixed bug #668: save command line history for yaz-client.
71 Fixed bug #830: pkg-config support.
75 Extended ZOOM result set options with two options that may be read by
76 a client: resultSetStatus and presentStatus with values as specified for
78 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
80 Fixed bug #827: Using SSL fails on Debian etch.
82 Fixed bug #826: Weird looking chars for set of MARC records.
84 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
85 that is treated as an ItemOrder with itemRequest being an XML document
86 external. The value of "doc" is the content.
88 Extended the GFS search facility. New member of bend_search_rr
89 'estimated_hit_count' signals that hits is known to be an estmate
90 (higher or lower than real hit count). New member 'partial_resultset'
91 signals that the search was partial (hit count is lower or equal than
92 real hit count). For Z39.50, the information is stored in resultSetStatus
93 member of SearchResponse APDU. For SRU, the information is signalled
94 via SRU diagnostic 59: "Result set created with valid partial results
97 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
101 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
103 Added ZOOM_connection_peek_event.
105 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
106 the following new functions:
107 ZOOM_event_nonblock, ZOOM_connection_process,
108 ZOOM_connection_get_{socket,mask,timeout},
109 ZOOM_connection_fire_event_{timeout,socket}.
110 The existing blocking event handler, ZOOM_event, is a wrapper for the
111 + blocking ZOOM_event_sys_{poll,select}.
113 Implemented function ccl_xml_config which parses XML version of CCL
114 configuration (bug #798).
116 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
118 Added timings utility (yaz/timing.h)
120 --- 2.1.44 2007/01/03
122 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
125 Fixed bug #779: Rotation of apdu.log fails.
127 Fixed for character set conversions:
128 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
129 Honor G1 set in MARC-8 decoding.
131 --- 2.1.42 2006/12/17
133 Fixed bug #775: char conversion does not handle Alternative UTF-8
136 Implemented function yaz_marc_read_line which parses MARC line format
137 records. There is a wealth of formats out there. So far, this function
138 reads line records produced by yaz_marc_write_line.
140 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
141 more generic and easier to remember(!) options: -i format and -o format
142 which specifies input format and output format respectively - where
143 format is one of "marc", "marcxml", "line", "marcxchange".
145 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
146 does not print anything except warnings for records.
148 For yaz-marcdump, added support for MARC split into files (-s) with a given
151 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
152 spec, at http://www.loc.gov/standards/sru/record-update/
153 This has changed the binary layout of the following structs:
154 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
155 bend_update_rr . Patch by Ko van der Sloot.
157 Added GFS utility function bend_assoc_is_alive which returns 1 if
158 association is still alive (client is connected); 0 otherwise (client
159 closed connection). This allows busy servers to stop working for
162 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
163 been a separate piece of software. This version of ziffy has been modified
164 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
166 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
168 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
169 Client code may now interrogate options such as "init_opt_sort" to
170 find out whether the server claims to support various options.
172 --- 2.1.40 2006/11/27
174 Added utilities yaz_{set,get}_esn to set/get element set name from
177 Removed the build of libyazthread.la. The libyaz.so is the threaded version
178 of YAZ and has been so since YAZ 2.1.10.
180 Implemented ZOOM_record_error which returns error information for
181 record (surrogate diagnostic).
183 --- 2.1.38 2006/10/31
185 Updates for SRU Update by Ko van der Sloot:
186 1. Changed name from "operation" to "action"
187 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
188 versions in the code, marked as 'backward compatible'.
189 3. Added diagnostics for SRU Update.
191 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
193 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
195 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
197 For GFS, fixed problem with SRU diagnostic 'First record position out of
198 range' being issued for 0 hits.
200 zoomtst10 part of Windows Build.
202 --- 2.1.36 2006/10/13
204 Implemented yaz_filepath_comp which splits a path into file path
205 components (required by Zebra 2.0.3+).
207 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
208 BSD inspired license until now so this should not have any real impact on
209 anybody. See http://www.opensource.org/licenses/bsd-license.php
211 Fixed bug #687: Missing log lines.
213 Fixed bug #678: CQL to PQF translation does not preserve double-quote
216 Fixed bug #689: SRU diagnostics to be added.
218 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
219 whether a connection is idle (no more work do do).
221 --- 2.1.34 2006/10/04
223 Change type of optval from long to int for invocation of setsockopt with
224 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
226 Added support for specifying the max log file size for the Generic
227 Frontend Server. The size is given with option -r.
229 --- 2.1.32 2006/09/21
231 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
233 --- 2.1.30 2006/09/17
235 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
238 Fixed bug in Generic Frontend Server that could cause a server to stop
239 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
241 For the generic frontend server, the maximum record size is used as maximum
242 size of incoming packages (SRU + Z39.50). The value until was previously
243 only used in Z39.50 Init negotiation and, later, in a session controlled
244 sizes of records returned. This is controlled using -k option. It can be
245 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
247 --- 2.1.28 2006/09/04
249 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
252 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
254 New option for yaz-marcdump -lpos=value which allows setting a portion
255 of MARC header to a certain value.
257 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
259 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
260 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
262 --- 2.1.26 2006/08/15
264 Fixed problem with SRU mode type (soap, get, post) for yaz-client
267 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
269 --- 2.1.24 2006/08/08
271 Fixed MARC ISO2709 encoding routines to deal with character set
274 Minor changes to GFS logging. Database included in search request log
277 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
278 cached/multiple records.
280 Shared libraries are built by default on Unix+configure.
282 Changed cql2pqf transformation to use a different evaluation order. The
283 new order is: always, relation, structure, position, truncation, index
284 and relationModifier. Old order was: always, relation, relationModifier,
285 structure, index, position, truncation. Note that the the latter ones
286 override former ones for identical attributes.. The new scheme means that
287 it is possible to override any existing attribute with a relationModifier.
288 And also that it is possible to override everything for the index rule
289 (except the ones listed in relationModifier). No order is perfect but this
290 one, we believe, covers more real cases.. The "always" should have been
291 called "default", since the attributes there can be overridden with all
294 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
295 compilation phase, but also for yaz-config --cflags output. This allows
296 us to have public headers with Libxml2 stuff in them . It should also,
297 eventually, make Libxml2 checks redundant in packages using YAZ, such
300 --- 2.1.22 2006/06/15
302 Changed SRU update structure bend_update_rr so that SRU diagnostics are
303 stored in uri, message and details.. Previously diagnostics were stored
304 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
305 compatibility.. but he's probably the only one affected, so.
307 Added support for CCL, compiled on the client side, in ZOOM-C. This
308 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
309 input; the resulting query objects can be used for for searching with
310 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
312 YAZ' configure searches for OpenSSL by default.
314 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
315 SL_CTX_use_certificate_file. See
316 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
317 for more info. Thanks to Ko van der Sloot.
319 --- 2.1.20 2006/06/02
321 Bug #600: SRU GET, POST support for yaz-client. Introduced
322 command 'sru' which selects method SOAP/GET/POST.
324 Allow missingValueAction to be specified for the sortspec string -
325 function yaz_sort_spec. By default, the missing value action is null.
326 Use ! to specify "abort". Use = followed by stringvalue to specify default
329 Ensured that Present-handler (if defined) is called in GFS before any call to
330 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
331 searchRetrieve requests.
333 Documentation for YAZ is now based on the Docbook XML/XSLT using
334 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
335 is no longer depending on jade/openjade or docbook-to-man scripts.
336 PDF is no longer part of the distribution - but can optionally be
337 made using DSSSL/jadetex or FOP.
339 Added retrieval handling support in Generic Frontend Server to support
340 conversion between MARC/XML as well as XSLTtransforms. See
341 etc/yazgfs.xml for an example.
343 Added Authentication support to Generic Frontend Server in SRU
344 mode. Authentication using HTTP Basic is supported, as is the use
345 of 'x-username' and 'x-password' parameters in the request itself.
347 Added support for a new character set MARC8s identical to MARC8 except
348 that it converts combined characters to single Unicode characters in the
349 Latin-1 range (when possible).
351 --- 2.1.18 2006/04/24
353 ASN.1 compiler 0.4: generates brief Doxygen file header for
354 generated .h/.c files.
356 Utility yaz_iconv now supports conversion to MARC-8.
358 New facilities for the MARC module. The reading - and writing of
359 content are separate methods for the yaz_marc_t handle. The following
360 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
361 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
362 format). Write functions have prefix yaz_marc_write_.. The existing
363 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
364 available. Removed support for OAI-MARC and simplexml (not the
365 simplexml from PHP5).
367 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
368 to be returned for this connection.
370 --- 2.1.16 2006/03/31
372 Allow multiple languages and charsets to be specified with
373 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
374 negcharset iso-8859-1,utf-8
376 Translation of proximity nodes from CQL into PQF now works.
378 Moved to automake 1.8, 1.9.
380 Added function yaz_log_set_handler which allows a log handler to be
381 installed. This handler will be called for all log messages. Output
382 to file is also produced; but that can be disabled by passing NULL
383 fname to yaz_log_init_file.
385 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
387 For SRW (including GFS), accept application/soap+xml as content-type
390 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
391 produces NO stylesheet reference even if a default stylesheet is specified
394 --- 2.1.14 2006/03/14
396 Updated Windows package to include yazd.dll + yazd.lib for the
397 Development component.
399 If the environment variable YAZ_LOG is set, then it is used as a
400 string indicating the default level of logging to use if not
401 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
402 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
403 used as before. So, for example, to omit warnings from YAZ logging,
406 cql_transform() now map structure and other attributes before indexes,
407 so that index-specific structures and other attributes can override
408 defaults. So now a combination of mapping specifications such as:
410 index.dc.date = 1=date-modified 4=5
411 does the right thing.
413 cql_transform() now also respects the "always" mapping specification,
414 which establishes an initial set of attributes to be used for all
415 terms except where overridden by more specific attributes associated
416 with the index, relation or modifier.
418 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
419 which mode to use; one of "post", "get" or "soap" (SRW, default).
421 Fixes for yaz_iconv routines: changed trie-based character set conversions
422 to use only non-negative values for bit fields due to Sun's C compiler not
423 supporting negative values.
425 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
426 sequences where not read correctly. Fix by Rustam Usmanov.
428 Updated win/makefile to use options, settings which makes things
429 compile with VS C 2005.
431 --- 2.1.12 2006/02/01
433 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
435 In ZOOM socket code, use select instead of poll on MacOSX.
437 ZOOM-C now support client-side compilation of CQL into RPN that is
438 sent to the server, enabling CQL to be used against all Z39.50
439 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
440 ZOOM_query object, and submit it using ZOOM_connection_search().
441 The CQL-to-RPN translation uses a configuration file, the name of
442 which must be specified in the Connection's "cqlfile" option.
444 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
445 function, which takes as its start-term parameter a ZOOM_query object
446 (which may have had either CQL or RPN set into it).
449 --- 2.1.10 2005/11/29
451 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
452 GFS to support this as well. Backend handler, bend_srw_update, does the
453 update work. Code contributed by Ko van der Sloot.
455 Allow retrieval of Search Result-1 information in ZOOM by the use of
456 options that are attached to a result set. ZOOM documentation updated
459 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
460 UTF-8 conversion. Patch by Raj Patel.
462 Added option -m to GFS to control formatting of timestamps in log file.
464 Added 'exit' as synonym for 'quit' in yaz-client
466 Added support for specifying SRW resultSetId + resultSetIdleTime in a
467 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
468 for the new members. Patch by Ko van der Sloot.
470 Added support for SRU POST. It is supported for content-type
471 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
473 Do not build the separate Multi-threaded (MT) library libyazthread.la.
474 Instead make the library libyaz.la multi-threaded. Threading as a whole
475 can still be disabled by configure option --disable-threads. Previosly,
476 with older GLIBCs there were problems with MT libs under Apache. This
477 has now been fixed a long time ago.
479 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
482 CQL module modified to be case insensitive for relations/indexes/operations.
484 Fixed bug in CQL transform code: incorrect value relationModifieder
487 Added 'show all' command for yaz-client which retrieves all results
490 Added new yaz-client, xmles, which takes a (private) OID and
491 a document to be sent as an extended service request.
493 Describe new yaz-client commands wait_response and set_auto_wait.
495 Increase TCP/IP listener backlog from 3 (which I am guessing was
496 copied from the SunOS manual entry way back when) so SOMAXCONN, so
497 that the socket will queue as many incoming connections as it's able
498 to handle ongoing connections. In other words, it will never now
499 refuse a connection that it would be able to handle merely because
500 it's not got around to accepting() enough of the pending connections
501 yet. This is the behaviour anyway under Linux, where the listen()
502 argument is ignored; but not under BSD and on systems such as
503 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
504 YAZ-based servers should now be uniform across operating systems in
507 yaz-marcdump uses 64-bit file access on some systems. This is enabled
508 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
509 This allows yaz-marcdump to read large MARC batches (>2 GB).
511 Modified all YAZ source files - except the source which is auto-generated
512 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
515 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
516 corresponding to the existing *_setl() function. These allow option
517 values containing arbitrary valuues.
519 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
520 ZOOM_resultset_sort() in new applications. Its behaviour is identical
521 except that it returns an indicator of whether or not the sort
522 criterion was accepted (0 for OK, -1 for invalid).
526 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
527 MARC output rather than returning "new" buffer.
529 yaz-client warns about unknown init options.
531 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
535 Added support for SRW sort in Generic Frontend Server. Patch
536 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
537 sortKeys - or NULL if none is provided.
539 Fixed bug #307: It was impossible to specify indefinite/no timeout
540 for ZOOM_event. Special timeout value -1 now means indefinite timeout
543 Added support for multiple languages and charsets to be specified in
544 ZOOM. Each charset/language is separated by a blank. If negotiation is
545 in effect in init-response, Option
546 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
547 Code based on patch by Vasiliy Osadchuk.
549 Fixed bug #306: infinite recursion that occurred when calling
550 yaz_log_level_init as the first call (before other log level or
553 Fixed bug in scan handling in front end server: if preferred-Position-In-
554 Response was non-present, a NULL pointer referece was performed.
558 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
559 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
560 now defined for all those error codes. So instead of putting 109 in
561 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
562 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
564 Modified the yaz-marcdump utility to skip garbage bytes between MARC
567 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
569 Program yaz-client now exits and produces an error message if multiple
570 Z39.50 servers are specified on the command line (none or one allowed
573 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
578 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
580 Fixed bug #272: Preserve spacing for CCL terms.
584 Added support for virtual hosts and multiple backend servers for
585 the YAZ frontend server. The configution is XML based and
586 support specificition of CQL to RPN mappings and explain information.
587 See section "Virtual Hosts" in the YAZ manual.
589 Extended OPAC display utility. OPAC display utility renders
590 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
591 to supplement yaz_marc_decode_wrbuf.
593 Fixed a bug in MARC decoder that could caused it to crash for some
594 invalid MARC records. More diagnostics and warnings where added in
595 XML output (warnings, etc are stored in comments).
597 --- 2.0.34 2005/02/08
599 Fixes for UNIX domain sockets. Bug #261.
601 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
603 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
604 Added yaz_marc_subfield_str which defines subfield lead string which is
605 used in YAZ_MARC_LINE format. Default string is blank+$. Added
606 yaz_marc_endline_str which defines end of fields string used in
607 YAZ_MARC_LINE format. Default string is newline.
609 Experimental support for MarcXChange. This format can be produced
610 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
611 http://www.bs.dk/standards/MarcXchange.xsd
613 Added yaz-client commands scansize that sets maximum number of
614 entries to be returned by scan.
616 --- 2.0.32 2005/01/11
618 Added support for SRW scan in yaz-client and Generic Frontend Server.
620 * Added whereInList member to SRW Scan Term.
622 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
624 Fixed NMEM system to return aligned blocks on the smallest boundaries
625 that are suitably aligned for all possible types on the particular
626 architecture YAZ is being built for.
628 --- 2.0.30 2005/01/04
630 Fixed numerious warnings that was issued with newer versions of GCC.
632 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
633 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
636 Make YAZ Generic Frontend Server slightly faster.
638 Enhance (and reduce) logging for Generic Frontend Server.
640 Revert YAZ log system so that it flushes every write operation
641 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
643 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
644 instead of LOG_, due to name clash with syslog(3). LOG_ are still
645 present. New applications should define YAZ_USE_NEW_LOG=1 - this
646 will effectively disable old definitions.
648 --- 2.0.28 2004/11/09
650 Added yaz_log_time_format which specifies log format using
653 Added yaz_log_module_level which returns mask for a module. Value
654 is non-zero mask a if module is enabled; zero if disabled.
656 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
657 in include/yaz/cql.h.
659 Fixed bug #176: Dont throw diagnostics on empty SRU args.
661 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
663 Fixed bug #172: RPM builds does not enable SSL.
665 Doxyfile.in part of dist. Doxyfile generated by configure.
667 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
668 are given and the corresponding component does not exist.
670 Extend CCL documentation in YAZ reference. Describe r=r.
672 --- 2.0.26 2004/10/01
674 Fixed MARC->MARCXML conversion to properly deal with
675 fields, subfields, indicators having non-ASCII characters.
677 Fixed MARC->MARCXML conversion so that ASCII control characters
678 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
681 Added YAZ GFS support for conversion from Z39.50 surrogate
682 diagnostics to SRW surrogate diagnostics.
684 Bug fix: YAZ GFS did not return schema in explainResponse.
686 --- 2.0.25 2004/09/30
688 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
689 now converts recordSchema to elementSetName as well as schema URI.
691 Fixed bug in COMSTACK that prevented HTTP request packages from being
694 --- 2.0.24 2004/09/29
696 Added CCL facility r=r "range" which is similar to r=o "ordered" but
697 does not require white-space before and after the dash in a range, e.g.
698 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
701 Fixed a few AC_TRY_LINK configure tests that did not operate properly
702 due to new GCC removing "redundant" code.
704 Added yaz-client commands scanpos and scanstep that sets preferred
705 position and step-size for scan.
707 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
709 Added CCL utility ccl_qual_buf which parses one or more CCL
710 spec lines in a buffer.
712 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
713 of name and value - ignoring empty lines and comments.
715 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
717 Added odr_get_element_path which returns current element path for an
718 ODR handle. This utility is useful in error handling or user-defined
721 Added ODR_PRINT utility odr_set_stream which is is a more generic
722 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
723 to a write function and pointer to close function. The close function - if
724 non-NULL - will be called during odr_destroy.
726 Fixed bug in CCL parser where truncation char was not removed from
727 right side when truncation=both was in effect.
729 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
732 --- 2.0.23 2004/08/11
734 Fix buffer overrun in CQL parser when dealing with proximity (%).
736 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
737 to UTF-8/UCS conversion is now only based on codetables.xml.
739 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
741 --- 2.0.22 2004/08/06
743 Add support for more "commit changes" in ZOOM (uses Extended Services).
745 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
748 Yet another small fix for configure of SSL.
750 --- 2.0.21 2004/05/14
752 Fix SSL libs for configure when --with-openssl=DIR is given.
754 --- 2.0.20 2004/05/10
756 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
758 SSL comstack now uses yaz.pem certificate file on server side
759 by default. Certificate filename can be configured by calling
760 comstack function cs_set_ssl_certificate_file before cs_bind is used.
762 Fix bug regarding multiple calls to ZOOM_connection_connect.
764 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
766 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
767 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
769 ZOOM now allows inspection of X509 peer certificate for verification.
770 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
772 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
773 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
774 as "modular" but it simplifies things.
776 Added cs_get_peer_certificate to that returns peer X509 PEM.
778 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
779 NULL if SSL is unavailable.
781 Documentation about MARC decoding tools.
783 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
785 --- 2.0.19 2004/03/30
787 Rename CHANGELOG to NEWS to follow GNU style packing.
789 Fix bug with missing initialization of member in init_diagnostics.
790 This bug affects threaded version of GFS server.
792 --- 2.0.18 2004/03/20
794 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
797 Ensure zlib.dll is packed with Windows install.
799 --- 2.0.17 2004/03/17
801 Fix encoding of xsd:string to use text instead of CDATA.
803 Fix endless loop in CQL parser with unbalanced ".
805 Use a more compact way to store MARC-8 conversion tables.
807 --- 2.0.16 2004/03/16 Debian only
809 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
812 Update CQL parser to use new CQL 1.1 modifiers for booleans and
817 --- 2.0.15 2004/03/01
819 Another fix for decoding of XML packed records.
821 --- 2.0.14 2004/02/25
823 Fixes for Chunked encoding. White space not ignored after length spec.
825 Update NS and use default NS for SRW diagnostic elements.
827 --- 2.0.13 2004/02/23
829 Implement ZOOM_resultset_cache_reset which resets record cache.
831 Implement ZOOM_resultset_sort which sorts a result set.
833 Implement chunked HTTP transfer.
835 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
837 --- 2.0.12 2004/02/16
839 Added member 'schema' to bend_explain_rr structure so that backend
840 can specify explain record identifier. Defaults to Zeerex 2.0.
842 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
844 --- 2.0.11 2004/02/16
846 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
849 Added init command for yaz-client which sends "extra" init request.
851 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
852 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
854 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
856 Make ZOOM error code for "invalid query".
858 Fixed compilation for SSL which wasn't properly enabled for all platforms.
860 --- 2.0.10 2004/02/05
862 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
865 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
867 Added option -p <file> to make Generic Frontend Server to write PID file.
869 Added option -D to put Generic Frontend Server in background on its own.
871 Make ZOOM C recognize option "password". If unset, "pass" is used
872 (for backwards compatibility).
874 Fixed a bug in Generic Frontend Server that could make it crash if a
875 client sets characterSetNegotation bit, but didn't pass negotiation stuff
878 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
879 Must be issued before open, in order to be in effect.
881 --- 2.0.9-6 2004/01/12 Debian/Windows
883 Make the SRU server more picky WRT unknown params, etc.
885 Bug fix: ZOOM scan response didn't return displayTerm - when present.
887 New YAZ client command, options, that sets Z39.50 options.
889 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
890 options from a string of tokens (one token for each option bit).
892 Update SRW diagnostic code messages.
894 --- 2.0.9-5 2004/01/07 Debian/Windows
896 Handle user defined stylesheet for SRW/SRU.
898 --- 2.0.9-4 2004/01/06 Debian/Windows
900 Fix bug in decoding of Content-Length.
902 --- 2.0.9-3 2004/01/06 Debian/Windows
904 Fix a bug with decoding of XML packed records.
906 --- 2.0.9-2 2004/01/05 Debian only
908 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
910 Fix bug in SRW/SRU diagnostics decoding.
914 Fixed bug in Generic Frontend Server which could drop records exceeding
915 preferred message size. Reported and fixed by Irina Dijour.
917 Fixed calculation of package size for structured records in Generic
918 Frontend Server. Reported and fixed by Irina Dijour.
920 Fixed namespace for SRW/SRU diagnostics.
922 Fixed SEGV in yaz-client that occured for HTTP connection errors.
926 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
927 this version is incompatible with version 1.0 and older YAZ SRW/SRU
930 CQL changes to reflect recent changes to the specification:
931 * Documentation talks about context sets instead of index sets.
932 * Documentation talks about indexes instead of qualifiers.
933 * The CQL-to-PQF transformer's configuration file now uses
934 "index.set.name = <attributes>" instead of the old form
935 "qualifier.set.name = <attributes>". (Both forms are still
936 understood but the latter is deprecated.)
937 * CQL terms with no explicit index specified are now interpreted as
938 cql.serverChoice instead of srw.serverChoice (which of course
939 behaves exactly the same.)
943 MARC conversion can now generate ISO2709 output in another
944 character set. yaz-marcdump uses this facility if you invoke it
947 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
948 functions from there can be used from C++.
952 Frontend server now transfers memory from decoded packages to stream
955 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
956 references to show up.
958 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
959 the ZOOM Abstract API. The older names for the same options are still
960 also supported for the benefit of old applications.
962 ZOOM-C supports "implementationId" and "implementationVersion" options
963 to go along with "implementationName". These allow the user code to
964 specify identification strings to be sent to servers.
965 Add OID for the new ExtLite attribute set.
967 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
968 as requested/supplid by Ere Maijala <ere@atp.fi>
970 For generic frontend server, reverse the order of
971 "toolkit-supplied / application-supplied" strings sent as implementationId,
972 Name and Version. Also, remove the spaces around the slash. This brings
973 the GFS in line with the behaviour of ZOOM-C on the client side.
975 Add function ZOOM_scanset_display_term.
977 yaz-client shows scan displayTerm if present.
979 Utility yaz-iconv is now installed by default along with the man page
982 Extend configure check for OpenSSL to use pkg-config where available (such
985 Incorporate patch by Morten Bogeskov which allows a Unix file socket
986 server to specify uid/gid/mask for socket using the format
987 unix:[user=uid,][group=gid,][umask=mask,]file=path
988 If file= is omitted the existing format is assumed, e.g.
990 in which case the mask is 0666 (rw for everybody).
992 Major restructure of YAZ source. All source in libyaz is in src directory.
993 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
994 util (utility programs such as ASN.1 compiler, yaz-marcdump).
996 Added man page for utility yaz-marcdump (used to be called marcdump).
997 yaz-marcdump is installed by 'make install'.
999 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1000 of incoming package failed.
1002 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1004 Change prototype of odr_perror: add const to message string.
1006 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1008 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1009 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1010 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1011 DNS lookup. There should not be any compatibility problems with this
1012 assuming that blocking=1 or 0 is used.
1014 Fix bad reference in UNIX comstack in function cs_addrstr.
1016 Fix for compilation on AIX.
1018 The generic front-end server (server/seshigh.c) now supports returning
1019 Init diagnostics to the client in User-information-field, in
1020 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1023 --- 2.0.4 2003/09/04
1025 Allow any CQL relation (not just all,any,exact,scr).
1027 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1028 that features the same UI.
1030 Implemented command update0 in YAZ client which is equivalent to
1031 update but uses old of Ext Update ASN.1.
1033 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1034 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1035 Previously no OID was used for this info.
1037 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1038 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1039 returns 'malformed search term' otherwise.
1041 SortResponse member resultCount now set to NULL in sort handler of
1044 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1047 Add three new utility functions for translating OIDs between various
1048 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1049 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1050 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1051 char *oid_to_dotstring(const int *oid, char *oidbuf);
1052 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1054 Reverted modifications for ES Update definition for z_IU0Update
1055 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1056 is back to YAZ 2.0.2.
1058 String value attributes for CCL parser.
1060 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1061 which their FirstSearch server returns in Init responses, sometimes
1062 carrying useful diagnostic information when Init fails. This has the
1063 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1064 "z39.50/oclcui.asn", where its definition is somewhat different from
1065 what OCLC document on their web-site, as required to interoperate with
1068 Support for anonymous authentication in yaz-client. Use the command
1071 * Fix the OID of the Index Data-local "admin" Extended Service from
1072 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1073 the 1000, which indicates a locally-defined OID, was a mistake.
1075 --- 2.0.3 2003/06/20
1077 Fix CCL directive @case handling so that it affects string match for
1078 both CCL keywords and qualifiers.
1080 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1081 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1082 Decoder has been updated with ASN.1 changes as listed in
1083 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1084 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1085 z_IUUpdate, remains unchanged.
1087 ZOOM_record_get may now return a record in a specific character set.
1088 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1089 "from" is the character set of record as returned by target. "to" is
1090 the character set to be returned. If omitted, "to" is UTF-8.
1092 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1094 New ODR utility, odr_getelement, which returns name of element for
1095 which encoding/decoding failed.
1097 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1098 in cases where a required element was omitted.
1100 Bug fix: some MARC8 sequences were not converted.
1102 New ZOOM option "step" which specifies number of records to be
1103 retrieved in one chunk. Used in conjunction with "start" and "count".
1105 SRW support for yaz-client. Use scheme http: to use it, e.g.
1108 yaz-client no longer does (un)intelligent character set conversions
1109 by default. Can be enabled with charset and marc_charset commands.
1111 xmalloc trace fix for 64-bit systems such as DEC alpha.
1113 Solaris 2.6 compile fix.
1115 New function, cql_strerror() translates SRW error codes, as returned
1116 by cql_transform_error(), into human-readable English strings. Used
1117 in yaz-client diagnostics when appropriate.
1119 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1120 converts it into a type-1 query which is sent to the server. This
1121 makes CQL available for use with all Z-servers, as opposed to the tiny
1122 minority that can handle CQL queries themselves.
1124 --- 2.0.2 2003/04/28
1126 New Debian package layout similar to the Redhat Package layout.
1128 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1129 and search result respectively.
1131 --- 2.0.1 2003/04/25
1133 Redhat package is now several packages: libyaz (runtime libraries),
1134 libyaz-devel (development and documentation, and yaz (utility programs).
1135 Package spec file by Morten Bøgeskov.
1137 New member 'schema' in struct bend_fetch_rr which the name of requested
1138 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1139 handler MAY set this to reflect the schema of the returned record.
1141 New member 'display_term' in struct scan_entry. GFS now sets member entries
1142 and allocates scan entries to be filled by user scan handler. In previous
1143 version, entries member was allocated by the scan handler. That still works,
1144 but the GFS will ignore member display_term - assuming it was NOT set by
1145 the handler. The fact that the GFS now allocates the entries both allows
1146 for new members and makes a scan handler easier to write.
1148 Fix CQL lex buffer overflow.
1150 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1151 SRU default recordPacking is string.
1153 SRU protocol support for frontend server.
1155 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1157 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1159 Added scan for the ZOOM shell (zoomsh).
1163 * String Identifers for Schemas (Amendment 5).
1164 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1165 Old definition for schema
1166 Odr_oid *schema; /* OPT */
1171 Z_InternationalString *uri;
1172 #define Z_Schema_oid 1
1173 #define Z_Schema_uri 2
1176 * resultCount parameter to Sort Response (Amendment 1).
1177 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1179 Support for SRW 1.0 over HTTP. This is an optional feature and
1180 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1183 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1184 on the same port. SRW SearchRetrieveRequests are mapped
1185 to bend_init,bend_search,bend_fetch,bend_close.
1187 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1189 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1190 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1192 ZOOM connections are SRW based if schem http is used for hostname
1193 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1194 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1196 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1197 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1198 distance=n, order=true/false, relation=le, prox unit=word. If
1199 n is omitted, distance 1 is used.
1201 Fixed problem with C compiler include path in wrong order.
1203 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1204 on Solaris. Patch from Ko van der Sloot.
1206 New MARC decode API. All new functions operate on a yaz_marc_t
1207 handle. The most important new functions are: yaz_marc_create,
1208 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1209 decode and destroy respectively. Decoder can produce formats
1210 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1211 include/yaz/marcdisp.h.
1213 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1214 to UTF-8, UCS-32, wchar_t or Latin-1.
1216 * Prototypes for yaz_iconv_-functions moved to separate header
1217 include/yaz/yaz-iconv.h.
1219 Make a few private functions 'static' in unix.c. This prevents
1220 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1222 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1223 are set when Init Response is received.
1225 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1226 but returns diagnostic set as well.
1228 New function yaz_strerror which is a portable wrapper for
1229 strerror/strerror_r/GetLastMessage.
1231 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1232 is returned for MARC. If type is "oai", then OAI MARC is returned.
1234 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1237 --- 1.9.2 2002/11/26
1239 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1241 Fix bad race conditions on SIGTERM and terminate gracefully in
1244 Move retrieval (data1) module to Zebra since nobody seems to be
1247 Add GRS-1 render for ZOOM using same format as yaz-client.
1249 --- 1.9.1 2002/10/05
1251 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1253 Fix broken ESpec handling in data1 module.
1255 SGML reader parses comments and makes them part of the data1 tree.
1257 Added several type casts so that YAZ compiles as C++ code.
1259 ZOOM didn't handle PDU encoding failures properly.
1261 Added more Bib-1 diagnostics (approved extensions).
1263 GNU configure: better check for iconv.
1265 More portable use of accept, getpeername. Check for socklen_t. Use
1266 int/size_t if socklen_t is not defined.
1270 PQF parser rejects bad queries - including those with extra
1271 characters in them. PQF parser used to silently ignore that.
1272 Cleaner API for PQF added, which allows you to get detailed
1273 error information for bad queries (see yaz/pquery.h).
1275 Fixed bug in ZOOM_record_get for type "database".
1277 Implemented mini iconv library supporting conversions between
1278 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1280 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1282 --- 1.8.9 2002/08/20
1284 Fixed ZOOM C record cache so that preferredRecordSyntax and
1285 elementSetName is used to check for already fetched records.
1287 --- 1.8.8 2002/08/02
1289 Added three members in bend_initrequest structure to facilitate
1290 character set negotiation.
1292 Fixed a bug in frontend server that could cause indefinite
1293 loops under rare conditions.
1295 Revised character set utilities (charneg.h) so that encoding
1296 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1298 For PQF, directive @term <type> sets term type for Scan/Search.
1299 Here <type> is general, string, numeric, null. The term type
1300 is inherited - just like @attr.
1302 New call odr_set_charset that sets character set conversion for
1303 international-strings on a ODR stream. Prototype is:
1304 int odr_set_charset(ODR o, const char *to, const char *from);
1305 The InternationalString is still represented as C string in YAZ
1306 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1307 won't). On the protocol level, you can use any encoding.
1309 Support for UNIX sockets in ZOOM.
1311 Solaris recv sometimes returns errno == ENOENT. It is treated as
1312 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1314 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1315 both client and server. Code by Morten Bøgeskov.
1317 --- 1.8.7 2002/05/22
1319 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1320 that they can be used directly from Visual Basic. You must recompile
1321 your windows APP if you're using ZOOM.
1323 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1324 Commands "lang" and "charset" sets language and character set respectively.
1325 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1326 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1328 Attributes from multiple CCL fields may be OR'ed rather than merged
1329 using directive "@field or". Fields are still merged by default -
1330 equivalent to "@field merge".
1332 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1335 Fixed bug in zget for parameter ExtendedServicesResponse.
1339 --- 1.8.6 2002/03/25
1341 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1343 Client displays USR.1:SearchResult-1 (hits per term).
1345 Additional Search Info for search in Generic Frontend Server.
1347 Fixed CCL parsing of "field=s".
1349 WIN32 installer - using the excellent NSIS software from nullsoft.
1351 Fixed CCL parsing of "field = - <number>".
1353 Added function yaz_marc_decode that decodes MARC for line mode
1354 display or XML (similar to that used by JZKit).
1356 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1357 Z39.50. But ISO/ILL was, however.
1359 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1360 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1362 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1363 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1365 --- 1.8.5 2002/02/03
1367 New YAZ client features: Command completion and new commands:
1368 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1369 Code provided by Jacob Poulsen.
1371 New call oid_trav, that visits all registered OIDs via callback.
1373 Function ZOOM_record_get now returns const char pointer rather than
1374 void pointer. It saves a lot of type casts.
1376 For YAZ client, command "auth" now allows you to set authentication
1377 in IdPass style. It is enabled when three tokens are given - order
1378 is user, group and password.
1380 Fix memory leaks in MARC record handling for ZOOM.
1382 New option for YAZ client, -k <kilobytes> that sets
1383 maximum record size. Similar to -k option for generic frontend
1384 server and yaz-ztest.
1386 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1388 Prefix query parser reports "fail" when bad attribute set is given.
1390 Fix in MARC decoder. Proximity logging. Fix for attribute set
1391 in scan handler for server. Patches by Shigeru Ishida.
1393 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1396 Configure option --with-openssl=<dir> now works when a directory is
1397 specified. Patch provided by Morten Bøgeskov.
1399 New option for YAZ client, -u <auth>, that sets authentication.
1401 ZOOM fix: error information was sometimes "missing", since error
1402 was cleared/reset too when it shouldn't.
1404 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1406 --- 1.8.4 2002/01/04
1408 Scan for ZOOM API. New object ZOOM_scanset. New functions
1409 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1410 ZOOM_scanset_destroy.
1412 New ZOOM function, ZOOM_connection_last_event, that returns type
1413 of last event (such as "receive data", "send data", "apdu received",
1416 New ZOOM option, schema, that specifies schema for retrieval.
1418 New CCL feature. Qualifiers can be aliases for one or more
1419 other qualifiers (if more than one is given, OR is used).
1421 ZOOM uses named result sets if target supports it.
1423 Two new YAZ client commands: . (dot, which sources a script of YAZ
1424 client commands), and ! (to execute shell command.). Implemented
1427 Working on Debian packages.
1429 --- 1.8.3 2001/11/19
1431 YAZ client enables named result sets only if target supports it.
1433 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1435 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1436 with key="host" to get same result.
1438 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1439 Function Z3950_resultset_record(s) returns references to records
1440 "owned" by resultset. To become owner use Z3950_record_clone.
1442 Function z_ext_record handles Extended Services. Thanks to
1445 --- 1.8.2 2001/11/12
1447 CCL Parser fix: ignore token comma when dealing with and-lists.
1449 Documentation updates for COMSTACK.
1451 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1452 Changed prototype Z3950_records. For some functions, int parameters
1453 were changed to size_t.
1455 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1458 New MARC decode/display function, marc_display_exl, which properly rejects
1459 non-ISO2709 records. YAZ client uses it.
1461 --- 1.8.1 2001/10/29
1463 Fix bug: local attribute set wasn't set correctly in PQF strings.
1467 * Old Z39.50 codecs no longer supported.
1469 Added ZOOM C binding. See http://zoom.z3950.org/
1471 Renamed states for COMSTACKs to avoid confusion with events.
1473 Implemented cs_look and proper cs_rcvconnect.
1475 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1477 Configure detects POSIX threads on OpenBSD.
1479 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1480 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1482 When error is returned from present handler, non-surrogate diagnostic
1483 is returned in present response (and fetch handler is no longer called).
1485 * Minor adjustments to pquery parser (PQF). Token characters may be
1486 escaped by using backslash (C-style).
1488 PQF parser allows string attribute values to be specified. For @attr,
1489 non-numeric characters after the equal-sign are treated as strings
1490 (e.g. @attr 9=title).
1492 CCL trunction character may be defined (@truncation in file)
1494 * function zget_ExtendedServicesRequest sets waitAction to
1495 waitIfPossible (was wait).
1497 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1500 CCL operator names may be set in field definition files (CCL_bibset).
1501 See ccl/bib1 for an example.
1503 Fixes in ASN.1 compiler for C++ compatibility.
1505 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1506 and "op_or" to avoid conflict with C++.
1508 Fixed problem with GNU readline detection on Redhat 7.0.
1510 Added step-size for Scan backend handler.
1512 Fixed bug that made the frontend server crash when no attribute
1513 set was specified for scan.
1515 Front-end server automatically switches to original working directory
1516 when installed as an NT service. Previously -w had to be specified to
1519 Added extended attributes for retrieval module (data1), so that data1
1520 records carry d1_readXML/SGML attributes. d1_read also supports
1521 null-data rules ( <tag/>)
1523 On UNIX when POSIX threads are available, a separate library libyazthread
1524 is created. Programmers should link with that library and the yaz library
1525 when using threads. The reason for the split was that some applications
1526 on Linux, such as Apache, doesn't work well when using shared objects that
1529 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1530 (or any frontend server) in SSL mode by specifying ssl: followed by
1531 address. Only tested on UNIX.
1533 Added feature for CCL module. Virtual structure s=al or s=ol generates
1534 and-list and or-list respectively instead of phrase search.
1538 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1539 log_mask_str. This was done to avoid name conflicts with other libraries
1540 (such as other PHP extensions).
1542 Added raw OID member for preferred record syntax (request_format_raw)
1543 and returned record syntax (output_format_raw) for backend fetch method.
1545 Config file yaz-config now accepts options so that it returns specific
1546 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1548 Shared library support for UNIX using GNU libtool.
1550 * Modified backend interface. Request/Response struct's replaced by
1551 one read/write C struct. For example bend_fetchrequest and
1552 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1553 Every handler - even search has to be registered in bend_init
1554 handler. This means that the YAZ library no longer refers to
1555 external functions and it makes it possible to make the whole
1556 thing a single DLL/SO.
1558 Added Segment handler for backend server.
1560 Added Zmbol/Zebra administrative functions to YAZ client.
1562 Threaded frontend server on UNIX (when POSIX Threads are available).
1563 Starting the server with option -T enables multi-threading.
1567 Added configure option --enable-comp/disable-comp to control use
1568 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1569 located in sub directory asn.
1571 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1572 in ${exec_prefix}/bin along with the other programs yaz-client and
1575 GNU automake used to maintain makefiles.
1577 Added several OID's.
1579 Changed retrieval module so that we can load records with no abstract
1580 syntax defined. Tagpaths in these records are fully composed of string
1583 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1587 On UNIX, the generated makefile now supports a proper 'make install'.
1588 The prefix can be set via GNU configure to set the install location
1589 (default is /usr/local).
1591 * YAZ programs client and ztest were renamed to yaz-client and
1592 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1593 locations, such as /usr/bin,/usr/local/bin,etc.
1595 * YAZ Header files were moved from include to include/yaz. YAZ Header
1596 files are referred to as include <yaz/log.h> rather than <log.h>.
1597 The YAZ include path (-I ..) is therefore the same as before. Programmers
1598 should update their #include statements or use -Ipath/include/yaz
1599 instead. The main motivation for doing this change is that YAZ header files
1600 can be installed in "standard" locations /usr/include,/usr/local/include
1601 without introducing conflicts, since ALL YAZ header files are stored
1602 in subdirectory yaz (under /usr/include for example).
1604 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1605 rather than project/workspace files. We switched because project files
1606 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1609 Changed name of logging function, logf, to yaz_log, to prevent name
1610 clash with some math-log functions. The YAZ header log.h defines logf
1611 to yaz_log (#define) so there should be no incompatibilities by this
1614 Added bend_start/bend_stop handlers for server. These handler are
1615 called on start/stop of server. For windows they are called whenever
1616 a service is started/stopped.
1618 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1619 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1620 in util/yc.tcl. The auto-generated C code structures are, in a few
1621 cases, incompatible with the old decoders. There are differences in the
1622 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1623 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1624 The preprocessor variable ASN_COMPILED is defined when the compiled
1625 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1626 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1627 wish to use the old encoders/decoders you can specify --disable-yc
1630 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1631 version so that it supports both new - and old version of DB Update
1633 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1634 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1635 change. The name parameter can be set to 0 in which no name is specified
1636 for the construction. The macros odr_implicit and odr_explicit sets name
1637 parameter to zero for the construction involved. New macros
1638 odr_implicit_tag and odr_explicit_tag are similar to the others,
1639 except that a name parameter is added. For programmers' that don't use
1640 ODR they probably only need to change the call to z_APDU and z_External.
1642 Added access control facility by interfacing the TCP wrapper library.
1643 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1644 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1645 name of the daemon and enables the access control as specified in
1646 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1648 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1649 den Dool <H.M.vdnDool@kub.nl>.
1651 Added reference ID parameter to most functions in server API - refer
1652 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1654 Changed name of ccl library to libccl.a (was ccl.a).
1656 Fixed bug in decoder for Explain (Category TargetInfo).
1658 Added support for GNU readline in client. Thanks to Jacob Poulsen
1659 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1661 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1662 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1663 IMPLEMENTATION! This change was made to the development version before
1664 the ZIG decided to retract the amendment. If any users MUST be
1665 compatible with the original Update definition, PLEASE CONTACT US, and
1666 we will include a separate definition corresponding to the old Update
1667 ES. Note that because of the change to the ASN.1 of the
1668 TaskPackageRecordStructure we cannot define a single structure that
1669 will support both versions.
1671 * Added const modifier to buffer parameter for some ODR/BER encoding
1672 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1673 completeWAIS, odr_dumpBER.
1675 Fixed bug in client.c which caused a crash when a scanResponse didn't
1676 contain positionOfTerm.
1678 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1679 * will cause an error in a client if a non-YAZ target sends both a
1680 * list of Scan entries and non-surrogate diagnostics.
1682 Retrieval module enhancements. Tag sets may be typed in the reference
1683 to it. From the .abs-file the "tagset" directive takes a third optional
1684 integer type for the tag set referenced. From a .tag-file the "include"
1685 directive takes a third optional type as well. The old "type" directive
1686 in the tag set itself is still recognized but acts as the default type
1689 Backend interface change. Individual Scan terms returned from bend_scan
1690 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1691 in include/backend.h.
1693 Retrieval module enhancements. Multiple tag sets and attribute sets may
1694 be specified in abstract syntax specs. Revised the error/warning for
1695 logging messages reported by the retrieval module when reading the
1698 Object Identifier system (oid_..) changed. The API is backwards
1699 compatible but the oid-routines now allocates new OID's when needed.
1700 Raw OID's may be specified in oid_getvalbyname.
1702 YAZ now uses GNU configure to generate Makefile(s).
1704 * Minor changes in some of the member names of DeleteResultSetRequest and
1705 DeleteResultSetResponse. See include/proto.h.
1707 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1708 and added member 'languages' in TargetInfo (which was missing).
1710 Changed the way attribute sets are handled in the retrieval
1711 module. These are now cached, just like the abstract syntaxes
1714 Changed YAZ so that it links with compiled ASN.1.
1716 Added Explain-schema definitions and mapping routines. The following
1717 Explain categories have been implemented: AttributeDetails,
1718 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1720 Fixed minor bug in Windows version of Server Library.
1722 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1724 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1726 Added EXTERNAL: UNIverse Resource Report (non-standard).
1728 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1729 ENUMERATED and SET OF.
1731 * Added 'const' to some of the char pointer arguments for the
1732 functions, data1_read_node, data1_getelementbytagname,
1733 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1736 Fixed bug in data1_insert_taggeddata - the last_child member of
1737 parent wasn't initialised.
1739 * Changed data1_read_record and data1_read_node so that the supplied
1740 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1741 doesn't refer to any parts of the "SGML"-buffer.
1743 Fixed bug in server library (Windows version of statserv_remove).
1745 * Changed code so that it compiles as C++. The type definition
1746 of Odr_fun which is a member of Odr_arm was changed. The result is,
1747 that an explicit typecast is needed for the fun pointer when
1748 using Odr_arm - as in:
1749 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1751 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1753 Implemented the new structured date and time definition as approved
1754 by the ZIG. Added schemaId element to the specificTag in Espec-1
1755 (also approved at the last ZIG). Thanks to RVDM.
1757 Added some Object identifiers (RVDM).
1759 Changed the Update Extended Service (RVDM).
1761 Added command "refid" to client which specifies referenceId for
1762 the following requests.
1764 Implemented extended service handling for server. See ztest.c
1765 for an example as well as backend.h. New handlers are registerd
1766 in the Init handler.
1768 * Changed interface for sort in server.
1770 Added new members to statserv_options_block. It allows a server
1771 to read options from another source than just the command line. Thanks
1772 to Charles Woodfield.
1774 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1775 renamed to zboolean. Some C++ compilers complained about the name.
1777 Minor changes to gils.abs. Added index 's' (sort) on title
1778 and date/time-last-modified.
1780 --- 1.4pl2 1998/1/30
1782 Fixed bug in server library regarding inetd mode (-i). This bug
1783 was introduced by release 1.4.
1785 --- 1.4pl1 1998/1/29
1787 Added sort facility in client and backend server interface.
1789 Fixed problem with dependencies in Makefile(s).
1791 Fixed bugs for encoders/decoders of extended services and
1794 Implemented sub-tree feature for schemas. Sub-trees are
1795 referenced in *.abs-files. See explain.abs for an example
1796 of the use of this feature.
1798 Modified bib1.att; local attributes for ANY didn't include
1799 ANY itself (only affects use of the retrieval module).
1801 Fixed bug in plain SGML reader in function data1_read_node:
1802 tags with prefix "var" was incorrectly interpreted as variants.
1804 Added feature "sub-schemas" to enable references to - and definitions
1805 of - group of elements.
1807 * Removed member parent from type data1_element (in data1.h).
1809 Implemented function odr_nullval() that returns the value of
1812 * Removed member num_children from data1_node (in data1.h).
1814 Made NT service interface part of the server library. The
1815 function statserv_main uses the NT service when required and
1816 calls the statserv_start / statserv_close routines.
1818 Routine zget_SearchRequest and zget_PresentRequest fills
1819 resultSetName/Id member with "default" instead of "Default".
1821 Fixed memory leak in server. Request queue member wasn't freed.
1823 Fixed nmem_exit so that memory is freed.
1827 Revised the CCL parser utility to be thread safe.
1829 Added function, oid_ent_to_oid, to replace the function
1830 oid_getoidbyent, which is not thread safe.
1832 * Added nmem_init and nmem_exit to initialize and release
1833 NMEM resources. Function nmem_init should be called once in the
1834 initial thread before NMEM/ODR is used. statserv.c and client.c
1835 have been changed accordingly. The change was necessary to make
1836 NMEM thread safe. The NMEM memory pool is shared amongst threads
1837 in a process. Unix-based applications will still work fine without
1840 Added NT Services interface for the the Z39.50 (statserv) Server.
1841 Refer to the ztest.c source on the usage.
1843 Windows 95/NT port using MSVC5.0. Project files are included in the
1846 * Defined new 'global' handle for the retrieval (data1) system. The
1847 new handled, data1_handle, describes the state of the data1 system.
1848 This handle is passed as first argument to virtually all
1849 data1 related routines. The functions data1_create and data1_destroy
1850 creates and destroys a data1 handle respectively.
1852 Added ODR encode stream member to all backend request structures
1853 init, search, scan etc. This stream should be used to allocate all
1854 memory used for the response when thread safe operation is needed.
1856 Changed the comstack utility, cs_addstr, to be thread safe. The
1857 returned hostname string returned by the function is now part the
1860 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1861 function. The cs_straddr takes a COMSTACK handle as argument, so this
1862 function must be used after cs_create and before bind/connect.
1863 This function is thread safe.
1865 Moved test server to 'ztest' directory - generic server code still
1866 in 'server' directory.
1868 Made prefix query (pquery.c) utility thread safe.
1870 Added new function modifier YAZ_EXPORT to 'export' public DLL
1871 functions when using windows (see include/yconfig.h).
1873 Added definitions to the OID database (util/oid.c) (RVDM).
1875 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1877 Added call to ccl_rpn_delete in client program.
1879 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1880 release of RPN structure.
1882 Added support for C++, headers uses extern "C" for public definitions.
1883 With input from RVDM.
1885 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1886 Thanks to Ronald van der Meer (RVDM).
1888 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1890 Added support for private extensions to the OID database
1891 (oid_setprivateoids()). Thanks to RVDM.
1893 Added optional, physical ANY (key replication)
1895 Fixed null-reference problem in GRS-1 output filter.
1897 Proximity operator added to Prefix Query Format (PQF).
1899 In test client command "base" accepts multiple databases.
1901 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1905 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1907 Smallish bug-fixes in the new encoders/decoders (explain).
1909 Bug fixed in DeleteRequest.
1911 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1913 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1915 Added SOIF syntax (using private OID for now) to retrieval module and client.
1917 Added Update extended service.
1919 Added SearchResult-1 additional info structure.
1921 Added optional CCL (ISO8777) interpreter as separate module. Available
1924 --- 1.2 1996/6/10 (1st anniversary release)
1926 Added Summary record syntax. Lightly tested.
1928 Added OPAC record syntax. Untested.
1930 Added ResourceReport service encoders/decoders. Untested.
1932 Fixed bug in z_Unit - wrong tagging on unitSystem.
1934 Fixed bug in the DiagRecs decoder.
1936 Added options for max PDU size and session timeout to frontend-server.
1938 Added documentation of query-language parsers and other supporting utilities.
1940 [frontend-server] Added Attribute set to the bend_scanrequest API.
1942 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1943 surrogate diagnostics were generated.
1945 [retrieval] Allow multiple local values for attribute.
1947 [retrieval] Allow multiple attributes per element in .abs files. index type.
1949 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1951 --- 1.1pl2 1996/4/10
1953 Minor changes, mostly specific to Zebra's requirements (retrieval)
1957 Repaired bug in frontend server when running multiple listening
1958 endpoints in dynamic mode.
1960 z_External() now won't break if a known, ASN.1 value comes encapsulated
1961 in an octet-string. The value will pass through unmodified in an Odr_oct.
1963 Added a bit of code to the demo client to decode & display
1964 ASN.1-structured records represented in the octet-aligned branch of
1965 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1967 Added z_ext_getentbyref() to the ASN module. Doc updated.
1969 * Completed the SCAN definition in the ASN module. This may break SCAN
1970 code based on older YAZ-versions at compile-time. The fix is easy -
1973 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1974 under the SCAN definition. Remember to initialize this, server-people.
1976 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1977 that this does not extend to ODR and ASN.
1979 Comstack allows insertion of established socket (primarily for
1980 inetd-operation of servers). Doc updated.
1982 Front-end server can now start from the inetd in TCP mode. Doc
1985 --- 1.0pl4 1996/1/24
1989 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1990 the rank and record number.
1992 Adjustments to the frontend server.
1994 Fixed diagnostic BER dumper. It ignored the file argument.
1998 Various changes to retrieval module.
2000 Changed the union discriminators of the protocol files from enums to
2001 ints paired with #defines.
2003 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2006 *Changed operator in the RPN structure to 'roperator', again to avoid a
2009 Fixed problems in Explain decoders/encoders.
2011 --- 1.0pl2 1995/12/6
2013 Memory bug in log module fixed.
2015 --- 1.0pl1 1995/12/5
2017 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2019 Bug in Explain DatabaseInfo module fixed.
2021 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2025 The shift to v1.0 signals that we now consider the *core* functionality
2026 of YAZ reasonably stable (the core being more or less equivalent to
2027 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2028 tested (Explain not at all - though that will happen soonish).
2030 Minor changes to code to support Windows port.
2032 Various minor changes after we're getting to use GRS-1 & co. more.
2034 Added Espec-1 format.
2036 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2037 of the protocol and it cannot be selected when encoding (maps into 'string'
2038 when decoding). Needed to talk to some servers.
2040 Demo client can request simple element set names.
2042 Added Diagnostic Format encoders/decoders.
2044 Added simple Close handling to frontend server (no hooks for resource
2045 reporting yet), and demonstration client.
2047 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2049 --- 1.0b3 1995/08/24
2051 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2052 handled incorrectly when records were requested in the searchResponse. This
2053 will only affect you if you use the frontend-server.
2055 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2056 Test-client will ask for and print GRS1. Ztest will return dummy records
2059 Added Explain encoders/decoders to the service-level API. Untested.
2061 Added Extended Services: Item Order encoders and decoders to the Service-
2062 level API. Untested. We could use a recent copy of the pertinent bits
2063 of the ILL protocol to add those bits.
2065 Added diagnostic format 1 encoders/decoders to the service-level API.
2068 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2069 odr_cons.c, which causes a more correct output.
2071 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2072 was always set to 0 when no records were requested in the searchRequest.
2074 * Added better external-handling. This shouldn't harm old code that
2075 *encodes* externals. It can break code that looks for a
2076 'single-ASN1-type' representation, since those types that are known
2077 are now decoded immediately. Look at the SUTRS sample code in
2078 seshigh.c and client.c. Documentation updated.
2080 Handling of structured records in bend_fetchresponse. Length -1 marks
2081 structured record, type is deduced from format field.
2083 --- 1.0b2 1995/06/27
2084 Fairly quick maintenance release to add SUTRS support.
2086 Fixed handling of SUTRS records in the demonstration client.
2088 * Added format field to the bend_fetchrequest and bend_fetchresponce
2089 structures of the backend API (frontend server). When the record is
2090 returned, the value of the format field is mapped to an OID. The
2091 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2092 of the record. The special value VAL_NONE in the bend_request means
2093 that no specific format was requested by the client. Documentation
2094 updated accordingly. Test server (ztest) will return a fixed dummy
2095 SUTRS record if your client requests SUTRS.
2097 Documentation updated accordingly.
2099 You can now set external libraries and RANLIB support in the top-level
2103 First public release.
