1 Implemented pass-through CQL-to-PQF conversions. Bug #861.
3 Fixed bug #832: Problem with MARC/charset in yaz-client.
5 Fixed bug #668: save command line history for yaz-client.
7 Fixed bug #830: pkg-config support.
11 Extended ZOOM result set options with two options that may be read by
12 a client: resultSetStatus and presentStatus with values as specified for
14 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
16 Fixed bug #827: Using SSL fails on Debian etch.
18 Fixed bug #826: Weird looking chars for set of MARC records.
20 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
21 that is treated as an ItemOrder with itemRequest being an XML document
22 external. The value of "doc" is the content.
24 Extended the GFS search facility. New member of bend_search_rr
25 'estimated_hit_count' signals that hits is known to be an estmate
26 (higher or lower than real hit count). New member 'partial_resultset'
27 signals that the search was partial (hit count is lower or equal than
28 real hit count). For Z39.50, the information is stored in resultSetStatus
29 member of SearchResponse APDU. For SRU, the information is signalled
30 via SRU diagnostic 59: "Result set created with valid partial results
33 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
37 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
39 Added ZOOM_connection_peek_event.
41 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
42 the following new functions:
43 ZOOM_event_nonblock, ZOOM_connection_process,
44 ZOOM_connection_get_{socket,mask,timeout},
45 ZOOM_connection_fire_event_{timeout,socket}.
46 The existing blocking event handler, ZOOM_event, is a wrapper for the
47 + blocking ZOOM_event_sys_{poll,select}.
49 Implemented function ccl_xml_config which parses XML version of CCL
50 configuration (bug #798).
52 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
54 Added timings utility (yaz/timing.h)
58 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
61 Fixed bug #779: Rotation of apdu.log fails.
63 Fixed for character set conversions:
64 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
65 Honor G1 set in MARC-8 decoding.
69 Fixed bug #775: char conversion does not handle Alternative UTF-8
72 Implemented function yaz_marc_read_line which parses MARC line format
73 records. There is a wealth of formats out there. So far, this function
74 reads line records produced by yaz_marc_write_line.
76 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
77 more generic and easier to remember(!) options: -i format and -o format
78 which specifies input format and output format respectively - where
79 format is one of "marc", "marcxml", "line", "marcxchange".
81 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
82 does not print anything except warnings for records.
84 For yaz-marcdump, added support for MARC split into files (-s) with a given
87 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
88 spec, at http://www.loc.gov/standards/sru/record-update/
89 This has changed the binary layout of the following structs:
90 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
91 bend_update_rr . Patch by Ko van der Sloot.
93 Added GFS utility function bend_assoc_is_alive which returns 1 if
94 association is still alive (client is connected); 0 otherwise (client
95 closed connection). This allows busy servers to stop working for
98 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
99 been a separate piece of software. This version of ziffy has been modified
100 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
102 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
104 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
105 Client code may now interrogate options such as "init_opt_sort" to
106 find out whether the server claims to support various options.
108 --- 2.1.40 2006/11/27
110 Added utilities yaz_{set,get}_esn to set/get element set name from
113 Removed the build of libyazthread.la. The libyaz.so is the threaded version
114 of YAZ and has been so since YAZ 2.1.10.
116 Implemented ZOOM_record_error which returns error information for
117 record (surrogate diagnostic).
119 --- 2.1.38 2006/10/31
121 Updates for SRU Update by Ko van der Sloot:
122 1. Changed name from "operation" to "action"
123 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
124 versions in the code, marked as 'backward compatible'.
125 3. Added diagnostics for SRU Update.
127 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
129 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
131 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
133 For GFS, fixed problem with SRU diagnostic 'First record position out of
134 range' being issued for 0 hits.
136 zoomtst10 part of Windows Build.
138 --- 2.1.36 2006/10/13
140 Implemented yaz_filepath_comp which splits a path into file path
141 components (required by Zebra 2.0.3+).
143 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
144 BSD inspired license until now so this should not have any real impact on
145 anybody. See http://www.opensource.org/licenses/bsd-license.php
147 Fixed bug #687: Missing log lines.
149 Fixed bug #678: CQL to PQF translation does not preserve double-quote
152 Fixed bug #689: SRU diagnostics to be added.
154 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
155 whether a connection is idle (no more work do do).
157 --- 2.1.34 2006/10/04
159 Change type of optval from long to int for invocation of setsockopt with
160 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
162 Added support for specifying the max log file size for the Generic
163 Frontend Server. The size is given with option -r.
165 --- 2.1.32 2006/09/21
167 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
169 --- 2.1.30 2006/09/17
171 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
174 Fixed bug in Generic Frontend Server that could cause a server to stop
175 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
177 For the generic frontend server, the maximum record size is used as maximum
178 size of incoming packages (SRU + Z39.50). The value until was previously
179 only used in Z39.50 Init negotiation and, later, in a session controlled
180 sizes of records returned. This is controlled using -k option. It can be
181 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
183 --- 2.1.28 2006/09/04
185 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
188 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
190 New option for yaz-marcdump -lpos=value which allows setting a portion
191 of MARC header to a certain value.
193 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
195 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
196 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
198 --- 2.1.26 2006/08/15
200 Fixed problem with SRU mode type (soap, get, post) for yaz-client
203 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
205 --- 2.1.24 2006/08/08
207 Fixed MARC ISO2709 encoding routines to deal with character set
210 Minor changes to GFS logging. Database included in search request log
213 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
214 cached/multiple records.
216 Shared libraries are built by default on Unix+configure.
218 Changed cql2pqf transformation to use a different evaluation order. The
219 new order is: always, relation, structure, position, truncation, index
220 and relationModifier. Old order was: always, relation, relationModifier,
221 structure, index, position, truncation. Note that the the latter ones
222 override former ones for identical attributes.. The new scheme means that
223 it is possible to override any existing attribute with a relationModifier.
224 And also that it is possible to override everything for the index rule
225 (except the ones listed in relationModifier). No order is perfect but this
226 one, we believe, covers more real cases.. The "always" should have been
227 called "default", since the attributes there can be overridden with all
230 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
231 compilation phase, but also for yaz-config --cflags output. This allows
232 us to have public headers with Libxml2 stuff in them . It should also,
233 eventually, make Libxml2 checks redundant in packages using YAZ, such
236 --- 2.1.22 2006/06/15
238 Changed SRU update structure bend_update_rr so that SRU diagnostics are
239 stored in uri, message and details.. Previously diagnostics were stored
240 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
241 compatibility.. but he's probably the only one affected, so.
243 Added support for CCL, compiled on the client side, in ZOOM-C. This
244 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
245 input; the resulting query objects can be used for for searching with
246 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
248 YAZ' configure searches for OpenSSL by default.
250 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
251 SL_CTX_use_certificate_file. See
252 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
253 for more info. Thanks to Ko van der Sloot.
255 --- 2.1.20 2006/06/02
257 Bug #600: SRU GET, POST support for yaz-client. Introduced
258 command 'sru' which selects method SOAP/GET/POST.
260 Allow missingValueAction to be specified for the sortspec string -
261 function yaz_sort_spec. By default, the missing value action is null.
262 Use ! to specify "abort". Use = followed by stringvalue to specify default
265 Ensured that Present-handler (if defined) is called in GFS before any call to
266 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
267 searchRetrieve requests.
269 Documentation for YAZ is now based on the Docbook XML/XSLT using
270 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
271 is no longer depending on jade/openjade or docbook-to-man scripts.
272 PDF is no longer part of the distribution - but can optionally be
273 made using DSSSL/jadetex or FOP.
275 Added retrieval handling support in Generic Frontend Server to support
276 conversion between MARC/XML as well as XSLTtransforms. See
277 etc/yazgfs.xml for an example.
279 Added Authentication support to Generic Frontend Server in SRU
280 mode. Authentication using HTTP Basic is supported, as is the use
281 of 'x-username' and 'x-password' parameters in the request itself.
283 Added support for a new character set MARC8s identical to MARC8 except
284 that it converts combined characters to single Unicode characters in the
285 Latin-1 range (when possible).
287 --- 2.1.18 2006/04/24
289 ASN.1 compiler 0.4: generates brief Doxygen file header for
290 generated .h/.c files.
292 Utility yaz_iconv now supports conversion to MARC-8.
294 New facilities for the MARC module. The reading - and writing of
295 content are separate methods for the yaz_marc_t handle. The following
296 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
297 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
298 format). Write functions have prefix yaz_marc_write_.. The existing
299 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
300 available. Removed support for OAI-MARC and simplexml (not the
301 simplexml from PHP5).
303 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
304 to be returned for this connection.
306 --- 2.1.16 2006/03/31
308 Allow multiple languages and charsets to be specified with
309 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
310 negcharset iso-8859-1,utf-8
312 Translation of proximity nodes from CQL into PQF now works.
314 Moved to automake 1.8, 1.9.
316 Added function yaz_log_set_handler which allows a log handler to be
317 installed. This handler will be called for all log messages. Output
318 to file is also produced; but that can be disabled by passing NULL
319 fname to yaz_log_init_file.
321 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
323 For SRW (including GFS), accept application/soap+xml as content-type
326 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
327 produces NO stylesheet reference even if a default stylesheet is specified
330 --- 2.1.14 2006/03/14
332 Updated Windows package to include yazd.dll + yazd.lib for the
333 Development component.
335 If the environment variable YAZ_LOG is set, then it is used as a
336 string indicating the default level of logging to use if not
337 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
338 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
339 used as before. So, for example, to omit warnings from YAZ logging,
342 cql_transform() now map structure and other attributes before indexes,
343 so that index-specific structures and other attributes can override
344 defaults. So now a combination of mapping specifications such as:
346 index.dc.date = 1=date-modified 4=5
347 does the right thing.
349 cql_transform() now also respects the "always" mapping specification,
350 which establishes an initial set of attributes to be used for all
351 terms except where overridden by more specific attributes associated
352 with the index, relation or modifier.
354 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
355 which mode to use; one of "post", "get" or "soap" (SRW, default).
357 Fixes for yaz_iconv routines: changed trie-based character set conversions
358 to use only non-negative values for bit fields due to Sun's C compiler not
359 supporting negative values.
361 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
362 sequences where not read correctly. Fix by Rustam Usmanov.
364 Updated win/makefile to use options, settings which makes things
365 compile with VS C 2005.
367 --- 2.1.12 2006/02/01
369 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
371 In ZOOM socket code, use select instead of poll on MacOSX.
373 ZOOM-C now support client-side compilation of CQL into RPN that is
374 sent to the server, enabling CQL to be used against all Z39.50
375 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
376 ZOOM_query object, and submit it using ZOOM_connection_search().
377 The CQL-to-RPN translation uses a configuration file, the name of
378 which must be specified in the Connection's "cqlfile" option.
380 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
381 function, which takes as its start-term parameter a ZOOM_query object
382 (which may have had either CQL or RPN set into it).
385 --- 2.1.10 2005/11/29
387 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
388 GFS to support this as well. Backend handler, bend_srw_update, does the
389 update work. Code contributed by Ko van der Sloot.
391 Allow retrieval of Search Result-1 information in ZOOM by the use of
392 options that are attached to a result set. ZOOM documentation updated
395 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
396 UTF-8 conversion. Patch by Raj Patel.
398 Added option -m to GFS to control formatting of timestamps in log file.
400 Added 'exit' as synonym for 'quit' in yaz-client
402 Added support for specifying SRW resultSetId + resultSetIdleTime in a
403 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
404 for the new members. Patch by Ko van der Sloot.
406 Added support for SRU POST. It is supported for content-type
407 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
409 Do not build the separate Multi-threaded (MT) library libyazthread.la.
410 Instead make the library libyaz.la multi-threaded. Threading as a whole
411 can still be disabled by configure option --disable-threads. Previosly,
412 with older GLIBCs there were problems with MT libs under Apache. This
413 has now been fixed a long time ago.
415 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
418 CQL module modified to be case insensitive for relations/indexes/operations.
420 Fixed bug in CQL transform code: incorrect value relationModifieder
423 Added 'show all' command for yaz-client which retrieves all results
426 Added new yaz-client, xmles, which takes a (private) OID and
427 a document to be sent as an extended service request.
429 Describe new yaz-client commands wait_response and set_auto_wait.
431 Increase TCP/IP listener backlog from 3 (which I am guessing was
432 copied from the SunOS manual entry way back when) so SOMAXCONN, so
433 that the socket will queue as many incoming connections as it's able
434 to handle ongoing connections. In other words, it will never now
435 refuse a connection that it would be able to handle merely because
436 it's not got around to accepting() enough of the pending connections
437 yet. This is the behaviour anyway under Linux, where the listen()
438 argument is ignored; but not under BSD and on systems such as
439 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
440 YAZ-based servers should now be uniform across operating systems in
443 yaz-marcdump uses 64-bit file access on some systems. This is enabled
444 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
445 This allows yaz-marcdump to read large MARC batches (>2 GB).
447 Modified all YAZ source files - except the source which is auto-generated
448 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
451 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
452 corresponding to the existing *_setl() function. These allow option
453 values containing arbitrary valuues.
455 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
456 ZOOM_resultset_sort() in new applications. Its behaviour is identical
457 except that it returns an indicator of whether or not the sort
458 criterion was accepted (0 for OK, -1 for invalid).
462 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
463 MARC output rather than returning "new" buffer.
465 yaz-client warns about unknown init options.
467 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
471 Added support for SRW sort in Generic Frontend Server. Patch
472 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
473 sortKeys - or NULL if none is provided.
475 Fixed bug #307: It was impossible to specify indefinite/no timeout
476 for ZOOM_event. Special timeout value -1 now means indefinite timeout
479 Added support for multiple languages and charsets to be specified in
480 ZOOM. Each charset/language is separated by a blank. If negotiation is
481 in effect in init-response, Option
482 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
483 Code based on patch by Vasiliy Osadchuk.
485 Fixed bug #306: infinite recursion that occurred when calling
486 yaz_log_level_init as the first call (before other log level or
489 Fixed bug in scan handling in front end server: if preferred-Position-In-
490 Response was non-present, a NULL pointer referece was performed.
494 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
495 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
496 now defined for all those error codes. So instead of putting 109 in
497 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
498 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
500 Modified the yaz-marcdump utility to skip garbage bytes between MARC
503 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
505 Program yaz-client now exits and produces an error message if multiple
506 Z39.50 servers are specified on the command line (none or one allowed
509 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
514 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
516 Fixed bug #272: Preserve spacing for CCL terms.
520 Added support for virtual hosts and multiple backend servers for
521 the YAZ frontend server. The configution is XML based and
522 support specificition of CQL to RPN mappings and explain information.
523 See section "Virtual Hosts" in the YAZ manual.
525 Extended OPAC display utility. OPAC display utility renders
526 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
527 to supplement yaz_marc_decode_wrbuf.
529 Fixed a bug in MARC decoder that could caused it to crash for some
530 invalid MARC records. More diagnostics and warnings where added in
531 XML output (warnings, etc are stored in comments).
533 --- 2.0.34 2005/02/08
535 Fixes for UNIX domain sockets. Bug #261.
537 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
539 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
540 Added yaz_marc_subfield_str which defines subfield lead string which is
541 used in YAZ_MARC_LINE format. Default string is blank+$. Added
542 yaz_marc_endline_str which defines end of fields string used in
543 YAZ_MARC_LINE format. Default string is newline.
545 Experimental support for MarcXChange. This format can be produced
546 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
547 http://www.bs.dk/standards/MarcXchange.xsd
549 Added yaz-client commands scansize that sets maximum number of
550 entries to be returned by scan.
552 --- 2.0.32 2005/01/11
554 Added support for SRW scan in yaz-client and Generic Frontend Server.
556 * Added whereInList member to SRW Scan Term.
558 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
560 Fixed NMEM system to return aligned blocks on the smallest boundaries
561 that are suitably aligned for all possible types on the particular
562 architecture YAZ is being built for.
564 --- 2.0.30 2005/01/04
566 Fixed numerious warnings that was issued with newer versions of GCC.
568 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
569 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
572 Make YAZ Generic Frontend Server slightly faster.
574 Enhance (and reduce) logging for Generic Frontend Server.
576 Revert YAZ log system so that it flushes every write operation
577 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
579 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
580 instead of LOG_, due to name clash with syslog(3). LOG_ are still
581 present. New applications should define YAZ_USE_NEW_LOG=1 - this
582 will effectively disable old definitions.
584 --- 2.0.28 2004/11/09
586 Added yaz_log_time_format which specifies log format using
589 Added yaz_log_module_level which returns mask for a module. Value
590 is non-zero mask a if module is enabled; zero if disabled.
592 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
593 in include/yaz/cql.h.
595 Fixed bug #176: Dont throw diagnostics on empty SRU args.
597 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
599 Fixed bug #172: RPM builds does not enable SSL.
601 Doxyfile.in part of dist. Doxyfile generated by configure.
603 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
604 are given and the corresponding component does not exist.
606 Extend CCL documentation in YAZ reference. Describe r=r.
608 --- 2.0.26 2004/10/01
610 Fixed MARC->MARCXML conversion to properly deal with
611 fields, subfields, indicators having non-ASCII characters.
613 Fixed MARC->MARCXML conversion so that ASCII control characters
614 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
617 Added YAZ GFS support for conversion from Z39.50 surrogate
618 diagnostics to SRW surrogate diagnostics.
620 Bug fix: YAZ GFS did not return schema in explainResponse.
622 --- 2.0.25 2004/09/30
624 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
625 now converts recordSchema to elementSetName as well as schema URI.
627 Fixed bug in COMSTACK that prevented HTTP request packages from being
630 --- 2.0.24 2004/09/29
632 Added CCL facility r=r "range" which is similar to r=o "ordered" but
633 does not require white-space before and after the dash in a range, e.g.
634 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
637 Fixed a few AC_TRY_LINK configure tests that did not operate properly
638 due to new GCC removing "redundant" code.
640 Added yaz-client commands scanpos and scanstep that sets preferred
641 position and step-size for scan.
643 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
645 Added CCL utility ccl_qual_buf which parses one or more CCL
646 spec lines in a buffer.
648 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
649 of name and value - ignoring empty lines and comments.
651 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
653 Added odr_get_element_path which returns current element path for an
654 ODR handle. This utility is useful in error handling or user-defined
657 Added ODR_PRINT utility odr_set_stream which is is a more generic
658 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
659 to a write function and pointer to close function. The close function - if
660 non-NULL - will be called during odr_destroy.
662 Fixed bug in CCL parser where truncation char was not removed from
663 right side when truncation=both was in effect.
665 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
668 --- 2.0.23 2004/08/11
670 Fix buffer overrun in CQL parser when dealing with proximity (%).
672 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
673 to UTF-8/UCS conversion is now only based on codetables.xml.
675 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
677 --- 2.0.22 2004/08/06
679 Add support for more "commit changes" in ZOOM (uses Extended Services).
681 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
684 Yet another small fix for configure of SSL.
686 --- 2.0.21 2004/05/14
688 Fix SSL libs for configure when --with-openssl=DIR is given.
690 --- 2.0.20 2004/05/10
692 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
694 SSL comstack now uses yaz.pem certificate file on server side
695 by default. Certificate filename can be configured by calling
696 comstack function cs_set_ssl_certificate_file before cs_bind is used.
698 Fix bug regarding multiple calls to ZOOM_connection_connect.
700 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
702 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
703 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
705 ZOOM now allows inspection of X509 peer certificate for verification.
706 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
708 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
709 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
710 as "modular" but it simplifies things.
712 Added cs_get_peer_certificate to that returns peer X509 PEM.
714 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
715 NULL if SSL is unavailable.
717 Documentation about MARC decoding tools.
719 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
721 --- 2.0.19 2004/03/30
723 Rename CHANGELOG to NEWS to follow GNU style packing.
725 Fix bug with missing initialization of member in init_diagnostics.
726 This bug affects threaded version of GFS server.
728 --- 2.0.18 2004/03/20
730 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
733 Ensure zlib.dll is packed with Windows install.
735 --- 2.0.17 2004/03/17
737 Fix encoding of xsd:string to use text instead of CDATA.
739 Fix endless loop in CQL parser with unbalanced ".
741 Use a more compact way to store MARC-8 conversion tables.
743 --- 2.0.16 2004/03/16 Debian only
745 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
748 Update CQL parser to use new CQL 1.1 modifiers for booleans and
753 --- 2.0.15 2004/03/01
755 Another fix for decoding of XML packed records.
757 --- 2.0.14 2004/02/25
759 Fixes for Chunked encoding. White space not ignored after length spec.
761 Update NS and use default NS for SRW diagnostic elements.
763 --- 2.0.13 2004/02/23
765 Implement ZOOM_resultset_cache_reset which resets record cache.
767 Implement ZOOM_resultset_sort which sorts a result set.
769 Implement chunked HTTP transfer.
771 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
773 --- 2.0.12 2004/02/16
775 Added member 'schema' to bend_explain_rr structure so that backend
776 can specify explain record identifier. Defaults to Zeerex 2.0.
778 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
780 --- 2.0.11 2004/02/16
782 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
785 Added init command for yaz-client which sends "extra" init request.
787 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
788 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
790 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
792 Make ZOOM error code for "invalid query".
794 Fixed compilation for SSL which wasn't properly enabled for all platforms.
796 --- 2.0.10 2004/02/05
798 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
801 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
803 Added option -p <file> to make Generic Frontend Server to write PID file.
805 Added option -D to put Generic Frontend Server in background on its own.
807 Make ZOOM C recognize option "password". If unset, "pass" is used
808 (for backwards compatibility).
810 Fixed a bug in Generic Frontend Server that could make it crash if a
811 client sets characterSetNegotation bit, but didn't pass negotiation stuff
814 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
815 Must be issued before open, in order to be in effect.
817 --- 2.0.9-6 2004/01/12 Debian/Windows
819 Make the SRU server more picky WRT unknown params, etc.
821 Bug fix: ZOOM scan response didn't return displayTerm - when present.
823 New YAZ client command, options, that sets Z39.50 options.
825 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
826 options from a string of tokens (one token for each option bit).
828 Update SRW diagnostic code messages.
830 --- 2.0.9-5 2004/01/07 Debian/Windows
832 Handle user defined stylesheet for SRW/SRU.
834 --- 2.0.9-4 2004/01/06 Debian/Windows
836 Fix bug in decoding of Content-Length.
838 --- 2.0.9-3 2004/01/06 Debian/Windows
840 Fix a bug with decoding of XML packed records.
842 --- 2.0.9-2 2004/01/05 Debian only
844 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
846 Fix bug in SRW/SRU diagnostics decoding.
850 Fixed bug in Generic Frontend Server which could drop records exceeding
851 preferred message size. Reported and fixed by Irina Dijour.
853 Fixed calculation of package size for structured records in Generic
854 Frontend Server. Reported and fixed by Irina Dijour.
856 Fixed namespace for SRW/SRU diagnostics.
858 Fixed SEGV in yaz-client that occured for HTTP connection errors.
862 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
863 this version is incompatible with version 1.0 and older YAZ SRW/SRU
866 CQL changes to reflect recent changes to the specification:
867 * Documentation talks about context sets instead of index sets.
868 * Documentation talks about indexes instead of qualifiers.
869 * The CQL-to-PQF transformer's configuration file now uses
870 "index.set.name = <attributes>" instead of the old form
871 "qualifier.set.name = <attributes>". (Both forms are still
872 understood but the latter is deprecated.)
873 * CQL terms with no explicit index specified are now interpreted as
874 cql.serverChoice instead of srw.serverChoice (which of course
875 behaves exactly the same.)
879 MARC conversion can now generate ISO2709 output in another
880 character set. yaz-marcdump uses this facility if you invoke it
883 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
884 functions from there can be used from C++.
888 Frontend server now transfers memory from decoded packages to stream
891 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
892 references to show up.
894 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
895 the ZOOM Abstract API. The older names for the same options are still
896 also supported for the benefit of old applications.
898 ZOOM-C supports "implementationId" and "implementationVersion" options
899 to go along with "implementationName". These allow the user code to
900 specify identification strings to be sent to servers.
901 Add OID for the new ExtLite attribute set.
903 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
904 as requested/supplid by Ere Maijala <ere@atp.fi>
906 For generic frontend server, reverse the order of
907 "toolkit-supplied / application-supplied" strings sent as implementationId,
908 Name and Version. Also, remove the spaces around the slash. This brings
909 the GFS in line with the behaviour of ZOOM-C on the client side.
911 Add function ZOOM_scanset_display_term.
913 yaz-client shows scan displayTerm if present.
915 Utility yaz-iconv is now installed by default along with the man page
918 Extend configure check for OpenSSL to use pkg-config where available (such
921 Incorporate patch by Morten Bogeskov which allows a Unix file socket
922 server to specify uid/gid/mask for socket using the format
923 unix:[user=uid,][group=gid,][umask=mask,]file=path
924 If file= is omitted the existing format is assumed, e.g.
926 in which case the mask is 0666 (rw for everybody).
928 Major restructure of YAZ source. All source in libyaz is in src directory.
929 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
930 util (utility programs such as ASN.1 compiler, yaz-marcdump).
932 Added man page for utility yaz-marcdump (used to be called marcdump).
933 yaz-marcdump is installed by 'make install'.
935 Fixed a memory leak in Generic Frontend Server that occurred when decoding
936 of incoming package failed.
938 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
940 Change prototype of odr_perror: add const to message string.
942 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
944 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
945 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
946 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
947 DNS lookup. There should not be any compatibility problems with this
948 assuming that blocking=1 or 0 is used.
950 Fix bad reference in UNIX comstack in function cs_addrstr.
952 Fix for compilation on AIX.
954 The generic front-end server (server/seshigh.c) now supports returning
955 Init diagnostics to the client in User-information-field, in
956 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
961 Allow any CQL relation (not just all,any,exact,scr).
963 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
964 that features the same UI.
966 Implemented command update0 in YAZ client which is equivalent to
967 update but uses old of Ext Update ASN.1.
969 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
970 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
971 Previously no OID was used for this info.
973 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
974 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
975 returns 'malformed search term' otherwise.
977 SortResponse member resultCount now set to NULL in sort handler of
980 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
983 Add three new utility functions for translating OIDs between various
984 formats -- symbolic name such as "Usmarc", minus-1-terminated int
985 arrays and dotted strings such as "1.2.840.10003.9.5.1":
986 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
987 char *oid_to_dotstring(const int *oid, char *oidbuf);
988 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
990 Reverted modifications for ES Update definition for z_IU0Update
991 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
992 is back to YAZ 2.0.2.
994 String value attributes for CCL parser.
996 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
997 which their FirstSearch server returns in Init responses, sometimes
998 carrying useful diagnostic information when Init fails. This has the
999 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1000 "z39.50/oclcui.asn", where its definition is somewhat different from
1001 what OCLC document on their web-site, as required to interoperate with
1004 Support for anonymous authentication in yaz-client. Use the command
1007 * Fix the OID of the Index Data-local "admin" Extended Service from
1008 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1009 the 1000, which indicates a locally-defined OID, was a mistake.
1011 --- 2.0.3 2003/06/20
1013 Fix CCL directive @case handling so that it affects string match for
1014 both CCL keywords and qualifiers.
1016 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1017 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1018 Decoder has been updated with ASN.1 changes as listed in
1019 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1020 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1021 z_IUUpdate, remains unchanged.
1023 ZOOM_record_get may now return a record in a specific character set.
1024 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1025 "from" is the character set of record as returned by target. "to" is
1026 the character set to be returned. If omitted, "to" is UTF-8.
1028 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1030 New ODR utility, odr_getelement, which returns name of element for
1031 which encoding/decoding failed.
1033 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1034 in cases where a required element was omitted.
1036 Bug fix: some MARC8 sequences were not converted.
1038 New ZOOM option "step" which specifies number of records to be
1039 retrieved in one chunk. Used in conjunction with "start" and "count".
1041 SRW support for yaz-client. Use scheme http: to use it, e.g.
1044 yaz-client no longer does (un)intelligent character set conversions
1045 by default. Can be enabled with charset and marc_charset commands.
1047 xmalloc trace fix for 64-bit systems such as DEC alpha.
1049 Solaris 2.6 compile fix.
1051 New function, cql_strerror() translates SRW error codes, as returned
1052 by cql_transform_error(), into human-readable English strings. Used
1053 in yaz-client diagnostics when appropriate.
1055 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1056 converts it into a type-1 query which is sent to the server. This
1057 makes CQL available for use with all Z-servers, as opposed to the tiny
1058 minority that can handle CQL queries themselves.
1060 --- 2.0.2 2003/04/28
1062 New Debian package layout similar to the Redhat Package layout.
1064 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1065 and search result respectively.
1067 --- 2.0.1 2003/04/25
1069 Redhat package is now several packages: libyaz (runtime libraries),
1070 libyaz-devel (development and documentation, and yaz (utility programs).
1071 Package spec file by Morten Bøgeskov.
1073 New member 'schema' in struct bend_fetch_rr which the name of requested
1074 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1075 handler MAY set this to reflect the schema of the returned record.
1077 New member 'display_term' in struct scan_entry. GFS now sets member entries
1078 and allocates scan entries to be filled by user scan handler. In previous
1079 version, entries member was allocated by the scan handler. That still works,
1080 but the GFS will ignore member display_term - assuming it was NOT set by
1081 the handler. The fact that the GFS now allocates the entries both allows
1082 for new members and makes a scan handler easier to write.
1084 Fix CQL lex buffer overflow.
1086 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1087 SRU default recordPacking is string.
1089 SRU protocol support for frontend server.
1091 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1093 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1095 Added scan for the ZOOM shell (zoomsh).
1099 * String Identifers for Schemas (Amendment 5).
1100 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1101 Old definition for schema
1102 Odr_oid *schema; /* OPT */
1107 Z_InternationalString *uri;
1108 #define Z_Schema_oid 1
1109 #define Z_Schema_uri 2
1112 * resultCount parameter to Sort Response (Amendment 1).
1113 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1115 Support for SRW 1.0 over HTTP. This is an optional feature and
1116 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1119 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1120 on the same port. SRW SearchRetrieveRequests are mapped
1121 to bend_init,bend_search,bend_fetch,bend_close.
1123 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1125 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1126 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1128 ZOOM connections are SRW based if schem http is used for hostname
1129 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1130 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1132 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1133 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1134 distance=n, order=true/false, relation=le, prox unit=word. If
1135 n is omitted, distance 1 is used.
1137 Fixed problem with C compiler include path in wrong order.
1139 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1140 on Solaris. Patch from Ko van der Sloot.
1142 New MARC decode API. All new functions operate on a yaz_marc_t
1143 handle. The most important new functions are: yaz_marc_create,
1144 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1145 decode and destroy respectively. Decoder can produce formats
1146 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1147 include/yaz/marcdisp.h.
1149 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1150 to UTF-8, UCS-32, wchar_t or Latin-1.
1152 * Prototypes for yaz_iconv_-functions moved to separate header
1153 include/yaz/yaz-iconv.h.
1155 Make a few private functions 'static' in unix.c. This prevents
1156 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1158 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1159 are set when Init Response is received.
1161 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1162 but returns diagnostic set as well.
1164 New function yaz_strerror which is a portable wrapper for
1165 strerror/strerror_r/GetLastMessage.
1167 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1168 is returned for MARC. If type is "oai", then OAI MARC is returned.
1170 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1173 --- 1.9.2 2002/11/26
1175 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1177 Fix bad race conditions on SIGTERM and terminate gracefully in
1180 Move retrieval (data1) module to Zebra since nobody seems to be
1183 Add GRS-1 render for ZOOM using same format as yaz-client.
1185 --- 1.9.1 2002/10/05
1187 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1189 Fix broken ESpec handling in data1 module.
1191 SGML reader parses comments and makes them part of the data1 tree.
1193 Added several type casts so that YAZ compiles as C++ code.
1195 ZOOM didn't handle PDU encoding failures properly.
1197 Added more Bib-1 diagnostics (approved extensions).
1199 GNU configure: better check for iconv.
1201 More portable use of accept, getpeername. Check for socklen_t. Use
1202 int/size_t if socklen_t is not defined.
1206 PQF parser rejects bad queries - including those with extra
1207 characters in them. PQF parser used to silently ignore that.
1208 Cleaner API for PQF added, which allows you to get detailed
1209 error information for bad queries (see yaz/pquery.h).
1211 Fixed bug in ZOOM_record_get for type "database".
1213 Implemented mini iconv library supporting conversions between
1214 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1216 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1218 --- 1.8.9 2002/08/20
1220 Fixed ZOOM C record cache so that preferredRecordSyntax and
1221 elementSetName is used to check for already fetched records.
1223 --- 1.8.8 2002/08/02
1225 Added three members in bend_initrequest structure to facilitate
1226 character set negotiation.
1228 Fixed a bug in frontend server that could cause indefinite
1229 loops under rare conditions.
1231 Revised character set utilities (charneg.h) so that encoding
1232 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1234 For PQF, directive @term <type> sets term type for Scan/Search.
1235 Here <type> is general, string, numeric, null. The term type
1236 is inherited - just like @attr.
1238 New call odr_set_charset that sets character set conversion for
1239 international-strings on a ODR stream. Prototype is:
1240 int odr_set_charset(ODR o, const char *to, const char *from);
1241 The InternationalString is still represented as C string in YAZ
1242 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1243 won't). On the protocol level, you can use any encoding.
1245 Support for UNIX sockets in ZOOM.
1247 Solaris recv sometimes returns errno == ENOENT. It is treated as
1248 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1250 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1251 both client and server. Code by Morten Bøgeskov.
1253 --- 1.8.7 2002/05/22
1255 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1256 that they can be used directly from Visual Basic. You must recompile
1257 your windows APP if you're using ZOOM.
1259 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1260 Commands "lang" and "charset" sets language and character set respectively.
1261 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1262 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1264 Attributes from multiple CCL fields may be OR'ed rather than merged
1265 using directive "@field or". Fields are still merged by default -
1266 equivalent to "@field merge".
1268 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1271 Fixed bug in zget for parameter ExtendedServicesResponse.
1275 --- 1.8.6 2002/03/25
1277 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1279 Client displays USR.1:SearchResult-1 (hits per term).
1281 Additional Search Info for search in Generic Frontend Server.
1283 Fixed CCL parsing of "field=s".
1285 WIN32 installer - using the excellent NSIS software from nullsoft.
1287 Fixed CCL parsing of "field = - <number>".
1289 Added function yaz_marc_decode that decodes MARC for line mode
1290 display or XML (similar to that used by JZKit).
1292 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1293 Z39.50. But ISO/ILL was, however.
1295 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1296 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1301 --- 1.8.5 2002/02/03
1303 New YAZ client features: Command completion and new commands:
1304 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1305 Code provided by Jacob Poulsen.
1307 New call oid_trav, that visits all registered OIDs via callback.
1309 Function ZOOM_record_get now returns const char pointer rather than
1310 void pointer. It saves a lot of type casts.
1312 For YAZ client, command "auth" now allows you to set authentication
1313 in IdPass style. It is enabled when three tokens are given - order
1314 is user, group and password.
1316 Fix memory leaks in MARC record handling for ZOOM.
1318 New option for YAZ client, -k <kilobytes> that sets
1319 maximum record size. Similar to -k option for generic frontend
1320 server and yaz-ztest.
1322 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1324 Prefix query parser reports "fail" when bad attribute set is given.
1326 Fix in MARC decoder. Proximity logging. Fix for attribute set
1327 in scan handler for server. Patches by Shigeru Ishida.
1329 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1332 Configure option --with-openssl=<dir> now works when a directory is
1333 specified. Patch provided by Morten Bøgeskov.
1335 New option for YAZ client, -u <auth>, that sets authentication.
1337 ZOOM fix: error information was sometimes "missing", since error
1338 was cleared/reset too when it shouldn't.
1340 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1342 --- 1.8.4 2002/01/04
1344 Scan for ZOOM API. New object ZOOM_scanset. New functions
1345 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1346 ZOOM_scanset_destroy.
1348 New ZOOM function, ZOOM_connection_last_event, that returns type
1349 of last event (such as "receive data", "send data", "apdu received",
1352 New ZOOM option, schema, that specifies schema for retrieval.
1354 New CCL feature. Qualifiers can be aliases for one or more
1355 other qualifiers (if more than one is given, OR is used).
1357 ZOOM uses named result sets if target supports it.
1359 Two new YAZ client commands: . (dot, which sources a script of YAZ
1360 client commands), and ! (to execute shell command.). Implemented
1363 Working on Debian packages.
1365 --- 1.8.3 2001/11/19
1367 YAZ client enables named result sets only if target supports it.
1369 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1371 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1372 with key="host" to get same result.
1374 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1375 Function Z3950_resultset_record(s) returns references to records
1376 "owned" by resultset. To become owner use Z3950_record_clone.
1378 Function z_ext_record handles Extended Services. Thanks to
1381 --- 1.8.2 2001/11/12
1383 CCL Parser fix: ignore token comma when dealing with and-lists.
1385 Documentation updates for COMSTACK.
1387 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1388 Changed prototype Z3950_records. For some functions, int parameters
1389 were changed to size_t.
1391 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1394 New MARC decode/display function, marc_display_exl, which properly rejects
1395 non-ISO2709 records. YAZ client uses it.
1397 --- 1.8.1 2001/10/29
1399 Fix bug: local attribute set wasn't set correctly in PQF strings.
1403 * Old Z39.50 codecs no longer supported.
1405 Added ZOOM C binding. See http://zoom.z3950.org/
1407 Renamed states for COMSTACKs to avoid confusion with events.
1409 Implemented cs_look and proper cs_rcvconnect.
1411 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1413 Configure detects POSIX threads on OpenBSD.
1415 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1416 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1418 When error is returned from present handler, non-surrogate diagnostic
1419 is returned in present response (and fetch handler is no longer called).
1421 * Minor adjustments to pquery parser (PQF). Token characters may be
1422 escaped by using backslash (C-style).
1424 PQF parser allows string attribute values to be specified. For @attr,
1425 non-numeric characters after the equal-sign are treated as strings
1426 (e.g. @attr 9=title).
1428 CCL trunction character may be defined (@truncation in file)
1430 * function zget_ExtendedServicesRequest sets waitAction to
1431 waitIfPossible (was wait).
1433 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1436 CCL operator names may be set in field definition files (CCL_bibset).
1437 See ccl/bib1 for an example.
1439 Fixes in ASN.1 compiler for C++ compatibility.
1441 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1442 and "op_or" to avoid conflict with C++.
1444 Fixed problem with GNU readline detection on Redhat 7.0.
1446 Added step-size for Scan backend handler.
1448 Fixed bug that made the frontend server crash when no attribute
1449 set was specified for scan.
1451 Front-end server automatically switches to original working directory
1452 when installed as an NT service. Previously -w had to be specified to
1455 Added extended attributes for retrieval module (data1), so that data1
1456 records carry d1_readXML/SGML attributes. d1_read also supports
1457 null-data rules ( <tag/>)
1459 On UNIX when POSIX threads are available, a separate library libyazthread
1460 is created. Programmers should link with that library and the yaz library
1461 when using threads. The reason for the split was that some applications
1462 on Linux, such as Apache, doesn't work well when using shared objects that
1465 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1466 (or any frontend server) in SSL mode by specifying ssl: followed by
1467 address. Only tested on UNIX.
1469 Added feature for CCL module. Virtual structure s=al or s=ol generates
1470 and-list and or-list respectively instead of phrase search.
1474 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1475 log_mask_str. This was done to avoid name conflicts with other libraries
1476 (such as other PHP extensions).
1478 Added raw OID member for preferred record syntax (request_format_raw)
1479 and returned record syntax (output_format_raw) for backend fetch method.
1481 Config file yaz-config now accepts options so that it returns specific
1482 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1484 Shared library support for UNIX using GNU libtool.
1486 * Modified backend interface. Request/Response struct's replaced by
1487 one read/write C struct. For example bend_fetchrequest and
1488 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1489 Every handler - even search has to be registered in bend_init
1490 handler. This means that the YAZ library no longer refers to
1491 external functions and it makes it possible to make the whole
1492 thing a single DLL/SO.
1494 Added Segment handler for backend server.
1496 Added Zmbol/Zebra administrative functions to YAZ client.
1498 Threaded frontend server on UNIX (when POSIX Threads are available).
1499 Starting the server with option -T enables multi-threading.
1503 Added configure option --enable-comp/disable-comp to control use
1504 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1505 located in sub directory asn.
1507 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1508 in ${exec_prefix}/bin along with the other programs yaz-client and
1511 GNU automake used to maintain makefiles.
1513 Added several OID's.
1515 Changed retrieval module so that we can load records with no abstract
1516 syntax defined. Tagpaths in these records are fully composed of string
1519 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1523 On UNIX, the generated makefile now supports a proper 'make install'.
1524 The prefix can be set via GNU configure to set the install location
1525 (default is /usr/local).
1527 * YAZ programs client and ztest were renamed to yaz-client and
1528 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1529 locations, such as /usr/bin,/usr/local/bin,etc.
1531 * YAZ Header files were moved from include to include/yaz. YAZ Header
1532 files are referred to as include <yaz/log.h> rather than <log.h>.
1533 The YAZ include path (-I ..) is therefore the same as before. Programmers
1534 should update their #include statements or use -Ipath/include/yaz
1535 instead. The main motivation for doing this change is that YAZ header files
1536 can be installed in "standard" locations /usr/include,/usr/local/include
1537 without introducing conflicts, since ALL YAZ header files are stored
1538 in subdirectory yaz (under /usr/include for example).
1540 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1541 rather than project/workspace files. We switched because project files
1542 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1545 Changed name of logging function, logf, to yaz_log, to prevent name
1546 clash with some math-log functions. The YAZ header log.h defines logf
1547 to yaz_log (#define) so there should be no incompatibilities by this
1550 Added bend_start/bend_stop handlers for server. These handler are
1551 called on start/stop of server. For windows they are called whenever
1552 a service is started/stopped.
1554 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1555 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1556 in util/yc.tcl. The auto-generated C code structures are, in a few
1557 cases, incompatible with the old decoders. There are differences in the
1558 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1559 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1560 The preprocessor variable ASN_COMPILED is defined when the compiled
1561 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1562 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1563 wish to use the old encoders/decoders you can specify --disable-yc
1566 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1567 version so that it supports both new - and old version of DB Update
1569 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1570 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1571 change. The name parameter can be set to 0 in which no name is specified
1572 for the construction. The macros odr_implicit and odr_explicit sets name
1573 parameter to zero for the construction involved. New macros
1574 odr_implicit_tag and odr_explicit_tag are similar to the others,
1575 except that a name parameter is added. For programmers' that don't use
1576 ODR they probably only need to change the call to z_APDU and z_External.
1578 Added access control facility by interfacing the TCP wrapper library.
1579 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1580 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1581 name of the daemon and enables the access control as specified in
1582 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1584 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1585 den Dool <H.M.vdnDool@kub.nl>.
1587 Added reference ID parameter to most functions in server API - refer
1588 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1590 Changed name of ccl library to libccl.a (was ccl.a).
1592 Fixed bug in decoder for Explain (Category TargetInfo).
1594 Added support for GNU readline in client. Thanks to Jacob Poulsen
1595 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1597 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1598 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1599 IMPLEMENTATION! This change was made to the development version before
1600 the ZIG decided to retract the amendment. If any users MUST be
1601 compatible with the original Update definition, PLEASE CONTACT US, and
1602 we will include a separate definition corresponding to the old Update
1603 ES. Note that because of the change to the ASN.1 of the
1604 TaskPackageRecordStructure we cannot define a single structure that
1605 will support both versions.
1607 * Added const modifier to buffer parameter for some ODR/BER encoding
1608 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1609 completeWAIS, odr_dumpBER.
1611 Fixed bug in client.c which caused a crash when a scanResponse didn't
1612 contain positionOfTerm.
1614 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1615 * will cause an error in a client if a non-YAZ target sends both a
1616 * list of Scan entries and non-surrogate diagnostics.
1618 Retrieval module enhancements. Tag sets may be typed in the reference
1619 to it. From the .abs-file the "tagset" directive takes a third optional
1620 integer type for the tag set referenced. From a .tag-file the "include"
1621 directive takes a third optional type as well. The old "type" directive
1622 in the tag set itself is still recognized but acts as the default type
1625 Backend interface change. Individual Scan terms returned from bend_scan
1626 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1627 in include/backend.h.
1629 Retrieval module enhancements. Multiple tag sets and attribute sets may
1630 be specified in abstract syntax specs. Revised the error/warning for
1631 logging messages reported by the retrieval module when reading the
1634 Object Identifier system (oid_..) changed. The API is backwards
1635 compatible but the oid-routines now allocates new OID's when needed.
1636 Raw OID's may be specified in oid_getvalbyname.
1638 YAZ now uses GNU configure to generate Makefile(s).
1640 * Minor changes in some of the member names of DeleteResultSetRequest and
1641 DeleteResultSetResponse. See include/proto.h.
1643 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1644 and added member 'languages' in TargetInfo (which was missing).
1646 Changed the way attribute sets are handled in the retrieval
1647 module. These are now cached, just like the abstract syntaxes
1650 Changed YAZ so that it links with compiled ASN.1.
1652 Added Explain-schema definitions and mapping routines. The following
1653 Explain categories have been implemented: AttributeDetails,
1654 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1656 Fixed minor bug in Windows version of Server Library.
1658 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1660 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1662 Added EXTERNAL: UNIverse Resource Report (non-standard).
1664 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1665 ENUMERATED and SET OF.
1667 * Added 'const' to some of the char pointer arguments for the
1668 functions, data1_read_node, data1_getelementbytagname,
1669 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1672 Fixed bug in data1_insert_taggeddata - the last_child member of
1673 parent wasn't initialised.
1675 * Changed data1_read_record and data1_read_node so that the supplied
1676 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1677 doesn't refer to any parts of the "SGML"-buffer.
1679 Fixed bug in server library (Windows version of statserv_remove).
1681 * Changed code so that it compiles as C++. The type definition
1682 of Odr_fun which is a member of Odr_arm was changed. The result is,
1683 that an explicit typecast is needed for the fun pointer when
1684 using Odr_arm - as in:
1685 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1687 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1689 Implemented the new structured date and time definition as approved
1690 by the ZIG. Added schemaId element to the specificTag in Espec-1
1691 (also approved at the last ZIG). Thanks to RVDM.
1693 Added some Object identifiers (RVDM).
1695 Changed the Update Extended Service (RVDM).
1697 Added command "refid" to client which specifies referenceId for
1698 the following requests.
1700 Implemented extended service handling for server. See ztest.c
1701 for an example as well as backend.h. New handlers are registerd
1702 in the Init handler.
1704 * Changed interface for sort in server.
1706 Added new members to statserv_options_block. It allows a server
1707 to read options from another source than just the command line. Thanks
1708 to Charles Woodfield.
1710 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1711 renamed to zboolean. Some C++ compilers complained about the name.
1713 Minor changes to gils.abs. Added index 's' (sort) on title
1714 and date/time-last-modified.
1716 --- 1.4pl2 1998/1/30
1718 Fixed bug in server library regarding inetd mode (-i). This bug
1719 was introduced by release 1.4.
1721 --- 1.4pl1 1998/1/29
1723 Added sort facility in client and backend server interface.
1725 Fixed problem with dependencies in Makefile(s).
1727 Fixed bugs for encoders/decoders of extended services and
1730 Implemented sub-tree feature for schemas. Sub-trees are
1731 referenced in *.abs-files. See explain.abs for an example
1732 of the use of this feature.
1734 Modified bib1.att; local attributes for ANY didn't include
1735 ANY itself (only affects use of the retrieval module).
1737 Fixed bug in plain SGML reader in function data1_read_node:
1738 tags with prefix "var" was incorrectly interpreted as variants.
1740 Added feature "sub-schemas" to enable references to - and definitions
1741 of - group of elements.
1743 * Removed member parent from type data1_element (in data1.h).
1745 Implemented function odr_nullval() that returns the value of
1748 * Removed member num_children from data1_node (in data1.h).
1750 Made NT service interface part of the server library. The
1751 function statserv_main uses the NT service when required and
1752 calls the statserv_start / statserv_close routines.
1754 Routine zget_SearchRequest and zget_PresentRequest fills
1755 resultSetName/Id member with "default" instead of "Default".
1757 Fixed memory leak in server. Request queue member wasn't freed.
1759 Fixed nmem_exit so that memory is freed.
1763 Revised the CCL parser utility to be thread safe.
1765 Added function, oid_ent_to_oid, to replace the function
1766 oid_getoidbyent, which is not thread safe.
1768 * Added nmem_init and nmem_exit to initialize and release
1769 NMEM resources. Function nmem_init should be called once in the
1770 initial thread before NMEM/ODR is used. statserv.c and client.c
1771 have been changed accordingly. The change was necessary to make
1772 NMEM thread safe. The NMEM memory pool is shared amongst threads
1773 in a process. Unix-based applications will still work fine without
1776 Added NT Services interface for the the Z39.50 (statserv) Server.
1777 Refer to the ztest.c source on the usage.
1779 Windows 95/NT port using MSVC5.0. Project files are included in the
1782 * Defined new 'global' handle for the retrieval (data1) system. The
1783 new handled, data1_handle, describes the state of the data1 system.
1784 This handle is passed as first argument to virtually all
1785 data1 related routines. The functions data1_create and data1_destroy
1786 creates and destroys a data1 handle respectively.
1788 Added ODR encode stream member to all backend request structures
1789 init, search, scan etc. This stream should be used to allocate all
1790 memory used for the response when thread safe operation is needed.
1792 Changed the comstack utility, cs_addstr, to be thread safe. The
1793 returned hostname string returned by the function is now part the
1796 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1797 function. The cs_straddr takes a COMSTACK handle as argument, so this
1798 function must be used after cs_create and before bind/connect.
1799 This function is thread safe.
1801 Moved test server to 'ztest' directory - generic server code still
1802 in 'server' directory.
1804 Made prefix query (pquery.c) utility thread safe.
1806 Added new function modifier YAZ_EXPORT to 'export' public DLL
1807 functions when using windows (see include/yconfig.h).
1809 Added definitions to the OID database (util/oid.c) (RVDM).
1811 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1813 Added call to ccl_rpn_delete in client program.
1815 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1816 release of RPN structure.
1818 Added support for C++, headers uses extern "C" for public definitions.
1819 With input from RVDM.
1821 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1822 Thanks to Ronald van der Meer (RVDM).
1824 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1826 Added support for private extensions to the OID database
1827 (oid_setprivateoids()). Thanks to RVDM.
1829 Added optional, physical ANY (key replication)
1831 Fixed null-reference problem in GRS-1 output filter.
1833 Proximity operator added to Prefix Query Format (PQF).
1835 In test client command "base" accepts multiple databases.
1837 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1841 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1843 Smallish bug-fixes in the new encoders/decoders (explain).
1845 Bug fixed in DeleteRequest.
1847 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1849 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1851 Added SOIF syntax (using private OID for now) to retrieval module and client.
1853 Added Update extended service.
1855 Added SearchResult-1 additional info structure.
1857 Added optional CCL (ISO8777) interpreter as separate module. Available
1860 --- 1.2 1996/6/10 (1st anniversary release)
1862 Added Summary record syntax. Lightly tested.
1864 Added OPAC record syntax. Untested.
1866 Added ResourceReport service encoders/decoders. Untested.
1868 Fixed bug in z_Unit - wrong tagging on unitSystem.
1870 Fixed bug in the DiagRecs decoder.
1872 Added options for max PDU size and session timeout to frontend-server.
1874 Added documentation of query-language parsers and other supporting utilities.
1876 [frontend-server] Added Attribute set to the bend_scanrequest API.
1878 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1879 surrogate diagnostics were generated.
1881 [retrieval] Allow multiple local values for attribute.
1883 [retrieval] Allow multiple attributes per element in .abs files. index type.
1885 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1887 --- 1.1pl2 1996/4/10
1889 Minor changes, mostly specific to Zebra's requirements (retrieval)
1893 Repaired bug in frontend server when running multiple listening
1894 endpoints in dynamic mode.
1896 z_External() now won't break if a known, ASN.1 value comes encapsulated
1897 in an octet-string. The value will pass through unmodified in an Odr_oct.
1899 Added a bit of code to the demo client to decode & display
1900 ASN.1-structured records represented in the octet-aligned branch of
1901 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1903 Added z_ext_getentbyref() to the ASN module. Doc updated.
1905 * Completed the SCAN definition in the ASN module. This may break SCAN
1906 code based on older YAZ-versions at compile-time. The fix is easy -
1909 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1910 under the SCAN definition. Remember to initialize this, server-people.
1912 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1913 that this does not extend to ODR and ASN.
1915 Comstack allows insertion of established socket (primarily for
1916 inetd-operation of servers). Doc updated.
1918 Front-end server can now start from the inetd in TCP mode. Doc
1921 --- 1.0pl4 1996/1/24
1925 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1926 the rank and record number.
1928 Adjustments to the frontend server.
1930 Fixed diagnostic BER dumper. It ignored the file argument.
1934 Various changes to retrieval module.
1936 Changed the union discriminators of the protocol files from enums to
1937 ints paired with #defines.
1939 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1942 *Changed operator in the RPN structure to 'roperator', again to avoid a
1945 Fixed problems in Explain decoders/encoders.
1947 --- 1.0pl2 1995/12/6
1949 Memory bug in log module fixed.
1951 --- 1.0pl1 1995/12/5
1953 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1955 Bug in Explain DatabaseInfo module fixed.
1957 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1961 The shift to v1.0 signals that we now consider the *core* functionality
1962 of YAZ reasonably stable (the core being more or less equivalent to
1963 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1964 tested (Explain not at all - though that will happen soonish).
1966 Minor changes to code to support Windows port.
1968 Various minor changes after we're getting to use GRS-1 & co. more.
1970 Added Espec-1 format.
1972 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1973 of the protocol and it cannot be selected when encoding (maps into 'string'
1974 when decoding). Needed to talk to some servers.
1976 Demo client can request simple element set names.
1978 Added Diagnostic Format encoders/decoders.
1980 Added simple Close handling to frontend server (no hooks for resource
1981 reporting yet), and demonstration client.
1983 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1985 --- 1.0b3 1995/08/24
1987 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1988 handled incorrectly when records were requested in the searchResponse. This
1989 will only affect you if you use the frontend-server.
1991 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1992 Test-client will ask for and print GRS1. Ztest will return dummy records
1995 Added Explain encoders/decoders to the service-level API. Untested.
1997 Added Extended Services: Item Order encoders and decoders to the Service-
1998 level API. Untested. We could use a recent copy of the pertinent bits
1999 of the ILL protocol to add those bits.
2001 Added diagnostic format 1 encoders/decoders to the service-level API.
2004 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2005 odr_cons.c, which causes a more correct output.
2007 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2008 was always set to 0 when no records were requested in the searchRequest.
2010 * Added better external-handling. This shouldn't harm old code that
2011 *encodes* externals. It can break code that looks for a
2012 'single-ASN1-type' representation, since those types that are known
2013 are now decoded immediately. Look at the SUTRS sample code in
2014 seshigh.c and client.c. Documentation updated.
2016 Handling of structured records in bend_fetchresponse. Length -1 marks
2017 structured record, type is deduced from format field.
2019 --- 1.0b2 1995/06/27
2020 Fairly quick maintenance release to add SUTRS support.
2022 Fixed handling of SUTRS records in the demonstration client.
2024 * Added format field to the bend_fetchrequest and bend_fetchresponce
2025 structures of the backend API (frontend server). When the record is
2026 returned, the value of the format field is mapped to an OID. The
2027 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2028 of the record. The special value VAL_NONE in the bend_request means
2029 that no specific format was requested by the client. Documentation
2030 updated accordingly. Test server (ztest) will return a fixed dummy
2031 SUTRS record if your client requests SUTRS.
2033 Documentation updated accordingly.
2035 You can now set external libraries and RANLIB support in the top-level
2039 First public release.
