1 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
3 Implemented pass-through CQL-to-PQF conversions. Bug #861.
5 Fixed bug #832: Problem with MARC/charset in yaz-client.
7 Fixed bug #668: save command line history for yaz-client.
9 Fixed bug #830: pkg-config support.
13 Extended ZOOM result set options with two options that may be read by
14 a client: resultSetStatus and presentStatus with values as specified for
16 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
18 Fixed bug #827: Using SSL fails on Debian etch.
20 Fixed bug #826: Weird looking chars for set of MARC records.
22 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
23 that is treated as an ItemOrder with itemRequest being an XML document
24 external. The value of "doc" is the content.
26 Extended the GFS search facility. New member of bend_search_rr
27 'estimated_hit_count' signals that hits is known to be an estmate
28 (higher or lower than real hit count). New member 'partial_resultset'
29 signals that the search was partial (hit count is lower or equal than
30 real hit count). For Z39.50, the information is stored in resultSetStatus
31 member of SearchResponse APDU. For SRU, the information is signalled
32 via SRU diagnostic 59: "Result set created with valid partial results
35 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
39 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
41 Added ZOOM_connection_peek_event.
43 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
44 the following new functions:
45 ZOOM_event_nonblock, ZOOM_connection_process,
46 ZOOM_connection_get_{socket,mask,timeout},
47 ZOOM_connection_fire_event_{timeout,socket}.
48 The existing blocking event handler, ZOOM_event, is a wrapper for the
49 + blocking ZOOM_event_sys_{poll,select}.
51 Implemented function ccl_xml_config which parses XML version of CCL
52 configuration (bug #798).
54 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
56 Added timings utility (yaz/timing.h)
60 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
63 Fixed bug #779: Rotation of apdu.log fails.
65 Fixed for character set conversions:
66 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
67 Honor G1 set in MARC-8 decoding.
71 Fixed bug #775: char conversion does not handle Alternative UTF-8
74 Implemented function yaz_marc_read_line which parses MARC line format
75 records. There is a wealth of formats out there. So far, this function
76 reads line records produced by yaz_marc_write_line.
78 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
79 more generic and easier to remember(!) options: -i format and -o format
80 which specifies input format and output format respectively - where
81 format is one of "marc", "marcxml", "line", "marcxchange".
83 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
84 does not print anything except warnings for records.
86 For yaz-marcdump, added support for MARC split into files (-s) with a given
89 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
90 spec, at http://www.loc.gov/standards/sru/record-update/
91 This has changed the binary layout of the following structs:
92 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
93 bend_update_rr . Patch by Ko van der Sloot.
95 Added GFS utility function bend_assoc_is_alive which returns 1 if
96 association is still alive (client is connected); 0 otherwise (client
97 closed connection). This allows busy servers to stop working for
100 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
101 been a separate piece of software. This version of ziffy has been modified
102 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
104 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
106 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
107 Client code may now interrogate options such as "init_opt_sort" to
108 find out whether the server claims to support various options.
110 --- 2.1.40 2006/11/27
112 Added utilities yaz_{set,get}_esn to set/get element set name from
115 Removed the build of libyazthread.la. The libyaz.so is the threaded version
116 of YAZ and has been so since YAZ 2.1.10.
118 Implemented ZOOM_record_error which returns error information for
119 record (surrogate diagnostic).
121 --- 2.1.38 2006/10/31
123 Updates for SRU Update by Ko van der Sloot:
124 1. Changed name from "operation" to "action"
125 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
126 versions in the code, marked as 'backward compatible'.
127 3. Added diagnostics for SRU Update.
129 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
131 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
133 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
135 For GFS, fixed problem with SRU diagnostic 'First record position out of
136 range' being issued for 0 hits.
138 zoomtst10 part of Windows Build.
140 --- 2.1.36 2006/10/13
142 Implemented yaz_filepath_comp which splits a path into file path
143 components (required by Zebra 2.0.3+).
145 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
146 BSD inspired license until now so this should not have any real impact on
147 anybody. See http://www.opensource.org/licenses/bsd-license.php
149 Fixed bug #687: Missing log lines.
151 Fixed bug #678: CQL to PQF translation does not preserve double-quote
154 Fixed bug #689: SRU diagnostics to be added.
156 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
157 whether a connection is idle (no more work do do).
159 --- 2.1.34 2006/10/04
161 Change type of optval from long to int for invocation of setsockopt with
162 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
164 Added support for specifying the max log file size for the Generic
165 Frontend Server. The size is given with option -r.
167 --- 2.1.32 2006/09/21
169 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
171 --- 2.1.30 2006/09/17
173 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
176 Fixed bug in Generic Frontend Server that could cause a server to stop
177 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
179 For the generic frontend server, the maximum record size is used as maximum
180 size of incoming packages (SRU + Z39.50). The value until was previously
181 only used in Z39.50 Init negotiation and, later, in a session controlled
182 sizes of records returned. This is controlled using -k option. It can be
183 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
185 --- 2.1.28 2006/09/04
187 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
190 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
192 New option for yaz-marcdump -lpos=value which allows setting a portion
193 of MARC header to a certain value.
195 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
197 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
198 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
200 --- 2.1.26 2006/08/15
202 Fixed problem with SRU mode type (soap, get, post) for yaz-client
205 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
207 --- 2.1.24 2006/08/08
209 Fixed MARC ISO2709 encoding routines to deal with character set
212 Minor changes to GFS logging. Database included in search request log
215 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
216 cached/multiple records.
218 Shared libraries are built by default on Unix+configure.
220 Changed cql2pqf transformation to use a different evaluation order. The
221 new order is: always, relation, structure, position, truncation, index
222 and relationModifier. Old order was: always, relation, relationModifier,
223 structure, index, position, truncation. Note that the the latter ones
224 override former ones for identical attributes.. The new scheme means that
225 it is possible to override any existing attribute with a relationModifier.
226 And also that it is possible to override everything for the index rule
227 (except the ones listed in relationModifier). No order is perfect but this
228 one, we believe, covers more real cases.. The "always" should have been
229 called "default", since the attributes there can be overridden with all
232 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
233 compilation phase, but also for yaz-config --cflags output. This allows
234 us to have public headers with Libxml2 stuff in them . It should also,
235 eventually, make Libxml2 checks redundant in packages using YAZ, such
238 --- 2.1.22 2006/06/15
240 Changed SRU update structure bend_update_rr so that SRU diagnostics are
241 stored in uri, message and details.. Previously diagnostics were stored
242 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
243 compatibility.. but he's probably the only one affected, so.
245 Added support for CCL, compiled on the client side, in ZOOM-C. This
246 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
247 input; the resulting query objects can be used for for searching with
248 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
250 YAZ' configure searches for OpenSSL by default.
252 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
253 SL_CTX_use_certificate_file. See
254 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
255 for more info. Thanks to Ko van der Sloot.
257 --- 2.1.20 2006/06/02
259 Bug #600: SRU GET, POST support for yaz-client. Introduced
260 command 'sru' which selects method SOAP/GET/POST.
262 Allow missingValueAction to be specified for the sortspec string -
263 function yaz_sort_spec. By default, the missing value action is null.
264 Use ! to specify "abort". Use = followed by stringvalue to specify default
267 Ensured that Present-handler (if defined) is called in GFS before any call to
268 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
269 searchRetrieve requests.
271 Documentation for YAZ is now based on the Docbook XML/XSLT using
272 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
273 is no longer depending on jade/openjade or docbook-to-man scripts.
274 PDF is no longer part of the distribution - but can optionally be
275 made using DSSSL/jadetex or FOP.
277 Added retrieval handling support in Generic Frontend Server to support
278 conversion between MARC/XML as well as XSLTtransforms. See
279 etc/yazgfs.xml for an example.
281 Added Authentication support to Generic Frontend Server in SRU
282 mode. Authentication using HTTP Basic is supported, as is the use
283 of 'x-username' and 'x-password' parameters in the request itself.
285 Added support for a new character set MARC8s identical to MARC8 except
286 that it converts combined characters to single Unicode characters in the
287 Latin-1 range (when possible).
289 --- 2.1.18 2006/04/24
291 ASN.1 compiler 0.4: generates brief Doxygen file header for
292 generated .h/.c files.
294 Utility yaz_iconv now supports conversion to MARC-8.
296 New facilities for the MARC module. The reading - and writing of
297 content are separate methods for the yaz_marc_t handle. The following
298 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
299 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
300 format). Write functions have prefix yaz_marc_write_.. The existing
301 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
302 available. Removed support for OAI-MARC and simplexml (not the
303 simplexml from PHP5).
305 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
306 to be returned for this connection.
308 --- 2.1.16 2006/03/31
310 Allow multiple languages and charsets to be specified with
311 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
312 negcharset iso-8859-1,utf-8
314 Translation of proximity nodes from CQL into PQF now works.
316 Moved to automake 1.8, 1.9.
318 Added function yaz_log_set_handler which allows a log handler to be
319 installed. This handler will be called for all log messages. Output
320 to file is also produced; but that can be disabled by passing NULL
321 fname to yaz_log_init_file.
323 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
325 For SRW (including GFS), accept application/soap+xml as content-type
328 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
329 produces NO stylesheet reference even if a default stylesheet is specified
332 --- 2.1.14 2006/03/14
334 Updated Windows package to include yazd.dll + yazd.lib for the
335 Development component.
337 If the environment variable YAZ_LOG is set, then it is used as a
338 string indicating the default level of logging to use if not
339 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
340 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
341 used as before. So, for example, to omit warnings from YAZ logging,
344 cql_transform() now map structure and other attributes before indexes,
345 so that index-specific structures and other attributes can override
346 defaults. So now a combination of mapping specifications such as:
348 index.dc.date = 1=date-modified 4=5
349 does the right thing.
351 cql_transform() now also respects the "always" mapping specification,
352 which establishes an initial set of attributes to be used for all
353 terms except where overridden by more specific attributes associated
354 with the index, relation or modifier.
356 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
357 which mode to use; one of "post", "get" or "soap" (SRW, default).
359 Fixes for yaz_iconv routines: changed trie-based character set conversions
360 to use only non-negative values for bit fields due to Sun's C compiler not
361 supporting negative values.
363 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
364 sequences where not read correctly. Fix by Rustam Usmanov.
366 Updated win/makefile to use options, settings which makes things
367 compile with VS C 2005.
369 --- 2.1.12 2006/02/01
371 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
373 In ZOOM socket code, use select instead of poll on MacOSX.
375 ZOOM-C now support client-side compilation of CQL into RPN that is
376 sent to the server, enabling CQL to be used against all Z39.50
377 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
378 ZOOM_query object, and submit it using ZOOM_connection_search().
379 The CQL-to-RPN translation uses a configuration file, the name of
380 which must be specified in the Connection's "cqlfile" option.
382 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
383 function, which takes as its start-term parameter a ZOOM_query object
384 (which may have had either CQL or RPN set into it).
387 --- 2.1.10 2005/11/29
389 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
390 GFS to support this as well. Backend handler, bend_srw_update, does the
391 update work. Code contributed by Ko van der Sloot.
393 Allow retrieval of Search Result-1 information in ZOOM by the use of
394 options that are attached to a result set. ZOOM documentation updated
397 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
398 UTF-8 conversion. Patch by Raj Patel.
400 Added option -m to GFS to control formatting of timestamps in log file.
402 Added 'exit' as synonym for 'quit' in yaz-client
404 Added support for specifying SRW resultSetId + resultSetIdleTime in a
405 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
406 for the new members. Patch by Ko van der Sloot.
408 Added support for SRU POST. It is supported for content-type
409 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
411 Do not build the separate Multi-threaded (MT) library libyazthread.la.
412 Instead make the library libyaz.la multi-threaded. Threading as a whole
413 can still be disabled by configure option --disable-threads. Previosly,
414 with older GLIBCs there were problems with MT libs under Apache. This
415 has now been fixed a long time ago.
417 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
420 CQL module modified to be case insensitive for relations/indexes/operations.
422 Fixed bug in CQL transform code: incorrect value relationModifieder
425 Added 'show all' command for yaz-client which retrieves all results
428 Added new yaz-client, xmles, which takes a (private) OID and
429 a document to be sent as an extended service request.
431 Describe new yaz-client commands wait_response and set_auto_wait.
433 Increase TCP/IP listener backlog from 3 (which I am guessing was
434 copied from the SunOS manual entry way back when) so SOMAXCONN, so
435 that the socket will queue as many incoming connections as it's able
436 to handle ongoing connections. In other words, it will never now
437 refuse a connection that it would be able to handle merely because
438 it's not got around to accepting() enough of the pending connections
439 yet. This is the behaviour anyway under Linux, where the listen()
440 argument is ignored; but not under BSD and on systems such as
441 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
442 YAZ-based servers should now be uniform across operating systems in
445 yaz-marcdump uses 64-bit file access on some systems. This is enabled
446 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
447 This allows yaz-marcdump to read large MARC batches (>2 GB).
449 Modified all YAZ source files - except the source which is auto-generated
450 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
453 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
454 corresponding to the existing *_setl() function. These allow option
455 values containing arbitrary valuues.
457 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
458 ZOOM_resultset_sort() in new applications. Its behaviour is identical
459 except that it returns an indicator of whether or not the sort
460 criterion was accepted (0 for OK, -1 for invalid).
464 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
465 MARC output rather than returning "new" buffer.
467 yaz-client warns about unknown init options.
469 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
473 Added support for SRW sort in Generic Frontend Server. Patch
474 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
475 sortKeys - or NULL if none is provided.
477 Fixed bug #307: It was impossible to specify indefinite/no timeout
478 for ZOOM_event. Special timeout value -1 now means indefinite timeout
481 Added support for multiple languages and charsets to be specified in
482 ZOOM. Each charset/language is separated by a blank. If negotiation is
483 in effect in init-response, Option
484 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
485 Code based on patch by Vasiliy Osadchuk.
487 Fixed bug #306: infinite recursion that occurred when calling
488 yaz_log_level_init as the first call (before other log level or
491 Fixed bug in scan handling in front end server: if preferred-Position-In-
492 Response was non-present, a NULL pointer referece was performed.
496 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
497 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
498 now defined for all those error codes. So instead of putting 109 in
499 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
500 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
502 Modified the yaz-marcdump utility to skip garbage bytes between MARC
505 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
507 Program yaz-client now exits and produces an error message if multiple
508 Z39.50 servers are specified on the command line (none or one allowed
511 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
516 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
518 Fixed bug #272: Preserve spacing for CCL terms.
522 Added support for virtual hosts and multiple backend servers for
523 the YAZ frontend server. The configution is XML based and
524 support specificition of CQL to RPN mappings and explain information.
525 See section "Virtual Hosts" in the YAZ manual.
527 Extended OPAC display utility. OPAC display utility renders
528 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
529 to supplement yaz_marc_decode_wrbuf.
531 Fixed a bug in MARC decoder that could caused it to crash for some
532 invalid MARC records. More diagnostics and warnings where added in
533 XML output (warnings, etc are stored in comments).
535 --- 2.0.34 2005/02/08
537 Fixes for UNIX domain sockets. Bug #261.
539 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
541 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
542 Added yaz_marc_subfield_str which defines subfield lead string which is
543 used in YAZ_MARC_LINE format. Default string is blank+$. Added
544 yaz_marc_endline_str which defines end of fields string used in
545 YAZ_MARC_LINE format. Default string is newline.
547 Experimental support for MarcXChange. This format can be produced
548 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
549 http://www.bs.dk/standards/MarcXchange.xsd
551 Added yaz-client commands scansize that sets maximum number of
552 entries to be returned by scan.
554 --- 2.0.32 2005/01/11
556 Added support for SRW scan in yaz-client and Generic Frontend Server.
558 * Added whereInList member to SRW Scan Term.
560 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
562 Fixed NMEM system to return aligned blocks on the smallest boundaries
563 that are suitably aligned for all possible types on the particular
564 architecture YAZ is being built for.
566 --- 2.0.30 2005/01/04
568 Fixed numerious warnings that was issued with newer versions of GCC.
570 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
571 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
574 Make YAZ Generic Frontend Server slightly faster.
576 Enhance (and reduce) logging for Generic Frontend Server.
578 Revert YAZ log system so that it flushes every write operation
579 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
581 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
582 instead of LOG_, due to name clash with syslog(3). LOG_ are still
583 present. New applications should define YAZ_USE_NEW_LOG=1 - this
584 will effectively disable old definitions.
586 --- 2.0.28 2004/11/09
588 Added yaz_log_time_format which specifies log format using
591 Added yaz_log_module_level which returns mask for a module. Value
592 is non-zero mask a if module is enabled; zero if disabled.
594 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
595 in include/yaz/cql.h.
597 Fixed bug #176: Dont throw diagnostics on empty SRU args.
599 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
601 Fixed bug #172: RPM builds does not enable SSL.
603 Doxyfile.in part of dist. Doxyfile generated by configure.
605 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
606 are given and the corresponding component does not exist.
608 Extend CCL documentation in YAZ reference. Describe r=r.
610 --- 2.0.26 2004/10/01
612 Fixed MARC->MARCXML conversion to properly deal with
613 fields, subfields, indicators having non-ASCII characters.
615 Fixed MARC->MARCXML conversion so that ASCII control characters
616 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
619 Added YAZ GFS support for conversion from Z39.50 surrogate
620 diagnostics to SRW surrogate diagnostics.
622 Bug fix: YAZ GFS did not return schema in explainResponse.
624 --- 2.0.25 2004/09/30
626 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
627 now converts recordSchema to elementSetName as well as schema URI.
629 Fixed bug in COMSTACK that prevented HTTP request packages from being
632 --- 2.0.24 2004/09/29
634 Added CCL facility r=r "range" which is similar to r=o "ordered" but
635 does not require white-space before and after the dash in a range, e.g.
636 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
639 Fixed a few AC_TRY_LINK configure tests that did not operate properly
640 due to new GCC removing "redundant" code.
642 Added yaz-client commands scanpos and scanstep that sets preferred
643 position and step-size for scan.
645 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
647 Added CCL utility ccl_qual_buf which parses one or more CCL
648 spec lines in a buffer.
650 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
651 of name and value - ignoring empty lines and comments.
653 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
655 Added odr_get_element_path which returns current element path for an
656 ODR handle. This utility is useful in error handling or user-defined
659 Added ODR_PRINT utility odr_set_stream which is is a more generic
660 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
661 to a write function and pointer to close function. The close function - if
662 non-NULL - will be called during odr_destroy.
664 Fixed bug in CCL parser where truncation char was not removed from
665 right side when truncation=both was in effect.
667 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
670 --- 2.0.23 2004/08/11
672 Fix buffer overrun in CQL parser when dealing with proximity (%).
674 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
675 to UTF-8/UCS conversion is now only based on codetables.xml.
677 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
679 --- 2.0.22 2004/08/06
681 Add support for more "commit changes" in ZOOM (uses Extended Services).
683 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
686 Yet another small fix for configure of SSL.
688 --- 2.0.21 2004/05/14
690 Fix SSL libs for configure when --with-openssl=DIR is given.
692 --- 2.0.20 2004/05/10
694 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
696 SSL comstack now uses yaz.pem certificate file on server side
697 by default. Certificate filename can be configured by calling
698 comstack function cs_set_ssl_certificate_file before cs_bind is used.
700 Fix bug regarding multiple calls to ZOOM_connection_connect.
702 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
704 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
705 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
707 ZOOM now allows inspection of X509 peer certificate for verification.
708 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
710 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
711 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
712 as "modular" but it simplifies things.
714 Added cs_get_peer_certificate to that returns peer X509 PEM.
716 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
717 NULL if SSL is unavailable.
719 Documentation about MARC decoding tools.
721 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
723 --- 2.0.19 2004/03/30
725 Rename CHANGELOG to NEWS to follow GNU style packing.
727 Fix bug with missing initialization of member in init_diagnostics.
728 This bug affects threaded version of GFS server.
730 --- 2.0.18 2004/03/20
732 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
735 Ensure zlib.dll is packed with Windows install.
737 --- 2.0.17 2004/03/17
739 Fix encoding of xsd:string to use text instead of CDATA.
741 Fix endless loop in CQL parser with unbalanced ".
743 Use a more compact way to store MARC-8 conversion tables.
745 --- 2.0.16 2004/03/16 Debian only
747 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
750 Update CQL parser to use new CQL 1.1 modifiers for booleans and
755 --- 2.0.15 2004/03/01
757 Another fix for decoding of XML packed records.
759 --- 2.0.14 2004/02/25
761 Fixes for Chunked encoding. White space not ignored after length spec.
763 Update NS and use default NS for SRW diagnostic elements.
765 --- 2.0.13 2004/02/23
767 Implement ZOOM_resultset_cache_reset which resets record cache.
769 Implement ZOOM_resultset_sort which sorts a result set.
771 Implement chunked HTTP transfer.
773 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
775 --- 2.0.12 2004/02/16
777 Added member 'schema' to bend_explain_rr structure so that backend
778 can specify explain record identifier. Defaults to Zeerex 2.0.
780 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
782 --- 2.0.11 2004/02/16
784 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
787 Added init command for yaz-client which sends "extra" init request.
789 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
790 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
792 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
794 Make ZOOM error code for "invalid query".
796 Fixed compilation for SSL which wasn't properly enabled for all platforms.
798 --- 2.0.10 2004/02/05
800 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
803 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
805 Added option -p <file> to make Generic Frontend Server to write PID file.
807 Added option -D to put Generic Frontend Server in background on its own.
809 Make ZOOM C recognize option "password". If unset, "pass" is used
810 (for backwards compatibility).
812 Fixed a bug in Generic Frontend Server that could make it crash if a
813 client sets characterSetNegotation bit, but didn't pass negotiation stuff
816 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
817 Must be issued before open, in order to be in effect.
819 --- 2.0.9-6 2004/01/12 Debian/Windows
821 Make the SRU server more picky WRT unknown params, etc.
823 Bug fix: ZOOM scan response didn't return displayTerm - when present.
825 New YAZ client command, options, that sets Z39.50 options.
827 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
828 options from a string of tokens (one token for each option bit).
830 Update SRW diagnostic code messages.
832 --- 2.0.9-5 2004/01/07 Debian/Windows
834 Handle user defined stylesheet for SRW/SRU.
836 --- 2.0.9-4 2004/01/06 Debian/Windows
838 Fix bug in decoding of Content-Length.
840 --- 2.0.9-3 2004/01/06 Debian/Windows
842 Fix a bug with decoding of XML packed records.
844 --- 2.0.9-2 2004/01/05 Debian only
846 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
848 Fix bug in SRW/SRU diagnostics decoding.
852 Fixed bug in Generic Frontend Server which could drop records exceeding
853 preferred message size. Reported and fixed by Irina Dijour.
855 Fixed calculation of package size for structured records in Generic
856 Frontend Server. Reported and fixed by Irina Dijour.
858 Fixed namespace for SRW/SRU diagnostics.
860 Fixed SEGV in yaz-client that occured for HTTP connection errors.
864 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
865 this version is incompatible with version 1.0 and older YAZ SRW/SRU
868 CQL changes to reflect recent changes to the specification:
869 * Documentation talks about context sets instead of index sets.
870 * Documentation talks about indexes instead of qualifiers.
871 * The CQL-to-PQF transformer's configuration file now uses
872 "index.set.name = <attributes>" instead of the old form
873 "qualifier.set.name = <attributes>". (Both forms are still
874 understood but the latter is deprecated.)
875 * CQL terms with no explicit index specified are now interpreted as
876 cql.serverChoice instead of srw.serverChoice (which of course
877 behaves exactly the same.)
881 MARC conversion can now generate ISO2709 output in another
882 character set. yaz-marcdump uses this facility if you invoke it
885 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
886 functions from there can be used from C++.
890 Frontend server now transfers memory from decoded packages to stream
893 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
894 references to show up.
896 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
897 the ZOOM Abstract API. The older names for the same options are still
898 also supported for the benefit of old applications.
900 ZOOM-C supports "implementationId" and "implementationVersion" options
901 to go along with "implementationName". These allow the user code to
902 specify identification strings to be sent to servers.
903 Add OID for the new ExtLite attribute set.
905 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
906 as requested/supplid by Ere Maijala <ere@atp.fi>
908 For generic frontend server, reverse the order of
909 "toolkit-supplied / application-supplied" strings sent as implementationId,
910 Name and Version. Also, remove the spaces around the slash. This brings
911 the GFS in line with the behaviour of ZOOM-C on the client side.
913 Add function ZOOM_scanset_display_term.
915 yaz-client shows scan displayTerm if present.
917 Utility yaz-iconv is now installed by default along with the man page
920 Extend configure check for OpenSSL to use pkg-config where available (such
923 Incorporate patch by Morten Bogeskov which allows a Unix file socket
924 server to specify uid/gid/mask for socket using the format
925 unix:[user=uid,][group=gid,][umask=mask,]file=path
926 If file= is omitted the existing format is assumed, e.g.
928 in which case the mask is 0666 (rw for everybody).
930 Major restructure of YAZ source. All source in libyaz is in src directory.
931 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
932 util (utility programs such as ASN.1 compiler, yaz-marcdump).
934 Added man page for utility yaz-marcdump (used to be called marcdump).
935 yaz-marcdump is installed by 'make install'.
937 Fixed a memory leak in Generic Frontend Server that occurred when decoding
938 of incoming package failed.
940 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
942 Change prototype of odr_perror: add const to message string.
944 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
946 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
947 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
948 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
949 DNS lookup. There should not be any compatibility problems with this
950 assuming that blocking=1 or 0 is used.
952 Fix bad reference in UNIX comstack in function cs_addrstr.
954 Fix for compilation on AIX.
956 The generic front-end server (server/seshigh.c) now supports returning
957 Init diagnostics to the client in User-information-field, in
958 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
963 Allow any CQL relation (not just all,any,exact,scr).
965 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
966 that features the same UI.
968 Implemented command update0 in YAZ client which is equivalent to
969 update but uses old of Ext Update ASN.1.
971 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
972 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
973 Previously no OID was used for this info.
975 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
976 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
977 returns 'malformed search term' otherwise.
979 SortResponse member resultCount now set to NULL in sort handler of
982 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
985 Add three new utility functions for translating OIDs between various
986 formats -- symbolic name such as "Usmarc", minus-1-terminated int
987 arrays and dotted strings such as "1.2.840.10003.9.5.1":
988 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
989 char *oid_to_dotstring(const int *oid, char *oidbuf);
990 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
992 Reverted modifications for ES Update definition for z_IU0Update
993 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
994 is back to YAZ 2.0.2.
996 String value attributes for CCL parser.
998 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
999 which their FirstSearch server returns in Init responses, sometimes
1000 carrying useful diagnostic information when Init fails. This has the
1001 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1002 "z39.50/oclcui.asn", where its definition is somewhat different from
1003 what OCLC document on their web-site, as required to interoperate with
1006 Support for anonymous authentication in yaz-client. Use the command
1009 * Fix the OID of the Index Data-local "admin" Extended Service from
1010 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1011 the 1000, which indicates a locally-defined OID, was a mistake.
1013 --- 2.0.3 2003/06/20
1015 Fix CCL directive @case handling so that it affects string match for
1016 both CCL keywords and qualifiers.
1018 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1019 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1020 Decoder has been updated with ASN.1 changes as listed in
1021 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1022 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1023 z_IUUpdate, remains unchanged.
1025 ZOOM_record_get may now return a record in a specific character set.
1026 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1027 "from" is the character set of record as returned by target. "to" is
1028 the character set to be returned. If omitted, "to" is UTF-8.
1030 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1032 New ODR utility, odr_getelement, which returns name of element for
1033 which encoding/decoding failed.
1035 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1036 in cases where a required element was omitted.
1038 Bug fix: some MARC8 sequences were not converted.
1040 New ZOOM option "step" which specifies number of records to be
1041 retrieved in one chunk. Used in conjunction with "start" and "count".
1043 SRW support for yaz-client. Use scheme http: to use it, e.g.
1046 yaz-client no longer does (un)intelligent character set conversions
1047 by default. Can be enabled with charset and marc_charset commands.
1049 xmalloc trace fix for 64-bit systems such as DEC alpha.
1051 Solaris 2.6 compile fix.
1053 New function, cql_strerror() translates SRW error codes, as returned
1054 by cql_transform_error(), into human-readable English strings. Used
1055 in yaz-client diagnostics when appropriate.
1057 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1058 converts it into a type-1 query which is sent to the server. This
1059 makes CQL available for use with all Z-servers, as opposed to the tiny
1060 minority that can handle CQL queries themselves.
1062 --- 2.0.2 2003/04/28
1064 New Debian package layout similar to the Redhat Package layout.
1066 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1067 and search result respectively.
1069 --- 2.0.1 2003/04/25
1071 Redhat package is now several packages: libyaz (runtime libraries),
1072 libyaz-devel (development and documentation, and yaz (utility programs).
1073 Package spec file by Morten Bøgeskov.
1075 New member 'schema' in struct bend_fetch_rr which the name of requested
1076 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1077 handler MAY set this to reflect the schema of the returned record.
1079 New member 'display_term' in struct scan_entry. GFS now sets member entries
1080 and allocates scan entries to be filled by user scan handler. In previous
1081 version, entries member was allocated by the scan handler. That still works,
1082 but the GFS will ignore member display_term - assuming it was NOT set by
1083 the handler. The fact that the GFS now allocates the entries both allows
1084 for new members and makes a scan handler easier to write.
1086 Fix CQL lex buffer overflow.
1088 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1089 SRU default recordPacking is string.
1091 SRU protocol support for frontend server.
1093 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1095 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1097 Added scan for the ZOOM shell (zoomsh).
1101 * String Identifers for Schemas (Amendment 5).
1102 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1103 Old definition for schema
1104 Odr_oid *schema; /* OPT */
1109 Z_InternationalString *uri;
1110 #define Z_Schema_oid 1
1111 #define Z_Schema_uri 2
1114 * resultCount parameter to Sort Response (Amendment 1).
1115 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1117 Support for SRW 1.0 over HTTP. This is an optional feature and
1118 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1121 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1122 on the same port. SRW SearchRetrieveRequests are mapped
1123 to bend_init,bend_search,bend_fetch,bend_close.
1125 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1127 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1128 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1130 ZOOM connections are SRW based if schem http is used for hostname
1131 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1132 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1134 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1135 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1136 distance=n, order=true/false, relation=le, prox unit=word. If
1137 n is omitted, distance 1 is used.
1139 Fixed problem with C compiler include path in wrong order.
1141 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1142 on Solaris. Patch from Ko van der Sloot.
1144 New MARC decode API. All new functions operate on a yaz_marc_t
1145 handle. The most important new functions are: yaz_marc_create,
1146 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1147 decode and destroy respectively. Decoder can produce formats
1148 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1149 include/yaz/marcdisp.h.
1151 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1152 to UTF-8, UCS-32, wchar_t or Latin-1.
1154 * Prototypes for yaz_iconv_-functions moved to separate header
1155 include/yaz/yaz-iconv.h.
1157 Make a few private functions 'static' in unix.c. This prevents
1158 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1160 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1161 are set when Init Response is received.
1163 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1164 but returns diagnostic set as well.
1166 New function yaz_strerror which is a portable wrapper for
1167 strerror/strerror_r/GetLastMessage.
1169 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1170 is returned for MARC. If type is "oai", then OAI MARC is returned.
1172 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1175 --- 1.9.2 2002/11/26
1177 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1179 Fix bad race conditions on SIGTERM and terminate gracefully in
1182 Move retrieval (data1) module to Zebra since nobody seems to be
1185 Add GRS-1 render for ZOOM using same format as yaz-client.
1187 --- 1.9.1 2002/10/05
1189 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1191 Fix broken ESpec handling in data1 module.
1193 SGML reader parses comments and makes them part of the data1 tree.
1195 Added several type casts so that YAZ compiles as C++ code.
1197 ZOOM didn't handle PDU encoding failures properly.
1199 Added more Bib-1 diagnostics (approved extensions).
1201 GNU configure: better check for iconv.
1203 More portable use of accept, getpeername. Check for socklen_t. Use
1204 int/size_t if socklen_t is not defined.
1208 PQF parser rejects bad queries - including those with extra
1209 characters in them. PQF parser used to silently ignore that.
1210 Cleaner API for PQF added, which allows you to get detailed
1211 error information for bad queries (see yaz/pquery.h).
1213 Fixed bug in ZOOM_record_get for type "database".
1215 Implemented mini iconv library supporting conversions between
1216 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1218 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1220 --- 1.8.9 2002/08/20
1222 Fixed ZOOM C record cache so that preferredRecordSyntax and
1223 elementSetName is used to check for already fetched records.
1225 --- 1.8.8 2002/08/02
1227 Added three members in bend_initrequest structure to facilitate
1228 character set negotiation.
1230 Fixed a bug in frontend server that could cause indefinite
1231 loops under rare conditions.
1233 Revised character set utilities (charneg.h) so that encoding
1234 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1236 For PQF, directive @term <type> sets term type for Scan/Search.
1237 Here <type> is general, string, numeric, null. The term type
1238 is inherited - just like @attr.
1240 New call odr_set_charset that sets character set conversion for
1241 international-strings on a ODR stream. Prototype is:
1242 int odr_set_charset(ODR o, const char *to, const char *from);
1243 The InternationalString is still represented as C string in YAZ
1244 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1245 won't). On the protocol level, you can use any encoding.
1247 Support for UNIX sockets in ZOOM.
1249 Solaris recv sometimes returns errno == ENOENT. It is treated as
1250 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1252 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1253 both client and server. Code by Morten Bøgeskov.
1255 --- 1.8.7 2002/05/22
1257 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1258 that they can be used directly from Visual Basic. You must recompile
1259 your windows APP if you're using ZOOM.
1261 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1262 Commands "lang" and "charset" sets language and character set respectively.
1263 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1264 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1266 Attributes from multiple CCL fields may be OR'ed rather than merged
1267 using directive "@field or". Fields are still merged by default -
1268 equivalent to "@field merge".
1270 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1273 Fixed bug in zget for parameter ExtendedServicesResponse.
1277 --- 1.8.6 2002/03/25
1279 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1281 Client displays USR.1:SearchResult-1 (hits per term).
1283 Additional Search Info for search in Generic Frontend Server.
1285 Fixed CCL parsing of "field=s".
1287 WIN32 installer - using the excellent NSIS software from nullsoft.
1289 Fixed CCL parsing of "field = - <number>".
1291 Added function yaz_marc_decode that decodes MARC for line mode
1292 display or XML (similar to that used by JZKit).
1294 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1295 Z39.50. But ISO/ILL was, however.
1297 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1298 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1301 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1303 --- 1.8.5 2002/02/03
1305 New YAZ client features: Command completion and new commands:
1306 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1307 Code provided by Jacob Poulsen.
1309 New call oid_trav, that visits all registered OIDs via callback.
1311 Function ZOOM_record_get now returns const char pointer rather than
1312 void pointer. It saves a lot of type casts.
1314 For YAZ client, command "auth" now allows you to set authentication
1315 in IdPass style. It is enabled when three tokens are given - order
1316 is user, group and password.
1318 Fix memory leaks in MARC record handling for ZOOM.
1320 New option for YAZ client, -k <kilobytes> that sets
1321 maximum record size. Similar to -k option for generic frontend
1322 server and yaz-ztest.
1324 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1326 Prefix query parser reports "fail" when bad attribute set is given.
1328 Fix in MARC decoder. Proximity logging. Fix for attribute set
1329 in scan handler for server. Patches by Shigeru Ishida.
1331 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1334 Configure option --with-openssl=<dir> now works when a directory is
1335 specified. Patch provided by Morten Bøgeskov.
1337 New option for YAZ client, -u <auth>, that sets authentication.
1339 ZOOM fix: error information was sometimes "missing", since error
1340 was cleared/reset too when it shouldn't.
1342 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1344 --- 1.8.4 2002/01/04
1346 Scan for ZOOM API. New object ZOOM_scanset. New functions
1347 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1348 ZOOM_scanset_destroy.
1350 New ZOOM function, ZOOM_connection_last_event, that returns type
1351 of last event (such as "receive data", "send data", "apdu received",
1354 New ZOOM option, schema, that specifies schema for retrieval.
1356 New CCL feature. Qualifiers can be aliases for one or more
1357 other qualifiers (if more than one is given, OR is used).
1359 ZOOM uses named result sets if target supports it.
1361 Two new YAZ client commands: . (dot, which sources a script of YAZ
1362 client commands), and ! (to execute shell command.). Implemented
1365 Working on Debian packages.
1367 --- 1.8.3 2001/11/19
1369 YAZ client enables named result sets only if target supports it.
1371 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1373 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1374 with key="host" to get same result.
1376 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1377 Function Z3950_resultset_record(s) returns references to records
1378 "owned" by resultset. To become owner use Z3950_record_clone.
1380 Function z_ext_record handles Extended Services. Thanks to
1383 --- 1.8.2 2001/11/12
1385 CCL Parser fix: ignore token comma when dealing with and-lists.
1387 Documentation updates for COMSTACK.
1389 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1390 Changed prototype Z3950_records. For some functions, int parameters
1391 were changed to size_t.
1393 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1396 New MARC decode/display function, marc_display_exl, which properly rejects
1397 non-ISO2709 records. YAZ client uses it.
1399 --- 1.8.1 2001/10/29
1401 Fix bug: local attribute set wasn't set correctly in PQF strings.
1405 * Old Z39.50 codecs no longer supported.
1407 Added ZOOM C binding. See http://zoom.z3950.org/
1409 Renamed states for COMSTACKs to avoid confusion with events.
1411 Implemented cs_look and proper cs_rcvconnect.
1413 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1415 Configure detects POSIX threads on OpenBSD.
1417 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1418 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1420 When error is returned from present handler, non-surrogate diagnostic
1421 is returned in present response (and fetch handler is no longer called).
1423 * Minor adjustments to pquery parser (PQF). Token characters may be
1424 escaped by using backslash (C-style).
1426 PQF parser allows string attribute values to be specified. For @attr,
1427 non-numeric characters after the equal-sign are treated as strings
1428 (e.g. @attr 9=title).
1430 CCL trunction character may be defined (@truncation in file)
1432 * function zget_ExtendedServicesRequest sets waitAction to
1433 waitIfPossible (was wait).
1435 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1438 CCL operator names may be set in field definition files (CCL_bibset).
1439 See ccl/bib1 for an example.
1441 Fixes in ASN.1 compiler for C++ compatibility.
1443 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1444 and "op_or" to avoid conflict with C++.
1446 Fixed problem with GNU readline detection on Redhat 7.0.
1448 Added step-size for Scan backend handler.
1450 Fixed bug that made the frontend server crash when no attribute
1451 set was specified for scan.
1453 Front-end server automatically switches to original working directory
1454 when installed as an NT service. Previously -w had to be specified to
1457 Added extended attributes for retrieval module (data1), so that data1
1458 records carry d1_readXML/SGML attributes. d1_read also supports
1459 null-data rules ( <tag/>)
1461 On UNIX when POSIX threads are available, a separate library libyazthread
1462 is created. Programmers should link with that library and the yaz library
1463 when using threads. The reason for the split was that some applications
1464 on Linux, such as Apache, doesn't work well when using shared objects that
1467 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1468 (or any frontend server) in SSL mode by specifying ssl: followed by
1469 address. Only tested on UNIX.
1471 Added feature for CCL module. Virtual structure s=al or s=ol generates
1472 and-list and or-list respectively instead of phrase search.
1476 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1477 log_mask_str. This was done to avoid name conflicts with other libraries
1478 (such as other PHP extensions).
1480 Added raw OID member for preferred record syntax (request_format_raw)
1481 and returned record syntax (output_format_raw) for backend fetch method.
1483 Config file yaz-config now accepts options so that it returns specific
1484 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1486 Shared library support for UNIX using GNU libtool.
1488 * Modified backend interface. Request/Response struct's replaced by
1489 one read/write C struct. For example bend_fetchrequest and
1490 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1491 Every handler - even search has to be registered in bend_init
1492 handler. This means that the YAZ library no longer refers to
1493 external functions and it makes it possible to make the whole
1494 thing a single DLL/SO.
1496 Added Segment handler for backend server.
1498 Added Zmbol/Zebra administrative functions to YAZ client.
1500 Threaded frontend server on UNIX (when POSIX Threads are available).
1501 Starting the server with option -T enables multi-threading.
1505 Added configure option --enable-comp/disable-comp to control use
1506 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1507 located in sub directory asn.
1509 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1510 in ${exec_prefix}/bin along with the other programs yaz-client and
1513 GNU automake used to maintain makefiles.
1515 Added several OID's.
1517 Changed retrieval module so that we can load records with no abstract
1518 syntax defined. Tagpaths in these records are fully composed of string
1521 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1525 On UNIX, the generated makefile now supports a proper 'make install'.
1526 The prefix can be set via GNU configure to set the install location
1527 (default is /usr/local).
1529 * YAZ programs client and ztest were renamed to yaz-client and
1530 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1531 locations, such as /usr/bin,/usr/local/bin,etc.
1533 * YAZ Header files were moved from include to include/yaz. YAZ Header
1534 files are referred to as include <yaz/log.h> rather than <log.h>.
1535 The YAZ include path (-I ..) is therefore the same as before. Programmers
1536 should update their #include statements or use -Ipath/include/yaz
1537 instead. The main motivation for doing this change is that YAZ header files
1538 can be installed in "standard" locations /usr/include,/usr/local/include
1539 without introducing conflicts, since ALL YAZ header files are stored
1540 in subdirectory yaz (under /usr/include for example).
1542 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1543 rather than project/workspace files. We switched because project files
1544 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1547 Changed name of logging function, logf, to yaz_log, to prevent name
1548 clash with some math-log functions. The YAZ header log.h defines logf
1549 to yaz_log (#define) so there should be no incompatibilities by this
1552 Added bend_start/bend_stop handlers for server. These handler are
1553 called on start/stop of server. For windows they are called whenever
1554 a service is started/stopped.
1556 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1557 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1558 in util/yc.tcl. The auto-generated C code structures are, in a few
1559 cases, incompatible with the old decoders. There are differences in the
1560 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1561 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1562 The preprocessor variable ASN_COMPILED is defined when the compiled
1563 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1564 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1565 wish to use the old encoders/decoders you can specify --disable-yc
1568 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1569 version so that it supports both new - and old version of DB Update
1571 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1572 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1573 change. The name parameter can be set to 0 in which no name is specified
1574 for the construction. The macros odr_implicit and odr_explicit sets name
1575 parameter to zero for the construction involved. New macros
1576 odr_implicit_tag and odr_explicit_tag are similar to the others,
1577 except that a name parameter is added. For programmers' that don't use
1578 ODR they probably only need to change the call to z_APDU and z_External.
1580 Added access control facility by interfacing the TCP wrapper library.
1581 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1582 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1583 name of the daemon and enables the access control as specified in
1584 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1586 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1587 den Dool <H.M.vdnDool@kub.nl>.
1589 Added reference ID parameter to most functions in server API - refer
1590 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1592 Changed name of ccl library to libccl.a (was ccl.a).
1594 Fixed bug in decoder for Explain (Category TargetInfo).
1596 Added support for GNU readline in client. Thanks to Jacob Poulsen
1597 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1599 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1600 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1601 IMPLEMENTATION! This change was made to the development version before
1602 the ZIG decided to retract the amendment. If any users MUST be
1603 compatible with the original Update definition, PLEASE CONTACT US, and
1604 we will include a separate definition corresponding to the old Update
1605 ES. Note that because of the change to the ASN.1 of the
1606 TaskPackageRecordStructure we cannot define a single structure that
1607 will support both versions.
1609 * Added const modifier to buffer parameter for some ODR/BER encoding
1610 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1611 completeWAIS, odr_dumpBER.
1613 Fixed bug in client.c which caused a crash when a scanResponse didn't
1614 contain positionOfTerm.
1616 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1617 * will cause an error in a client if a non-YAZ target sends both a
1618 * list of Scan entries and non-surrogate diagnostics.
1620 Retrieval module enhancements. Tag sets may be typed in the reference
1621 to it. From the .abs-file the "tagset" directive takes a third optional
1622 integer type for the tag set referenced. From a .tag-file the "include"
1623 directive takes a third optional type as well. The old "type" directive
1624 in the tag set itself is still recognized but acts as the default type
1627 Backend interface change. Individual Scan terms returned from bend_scan
1628 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1629 in include/backend.h.
1631 Retrieval module enhancements. Multiple tag sets and attribute sets may
1632 be specified in abstract syntax specs. Revised the error/warning for
1633 logging messages reported by the retrieval module when reading the
1636 Object Identifier system (oid_..) changed. The API is backwards
1637 compatible but the oid-routines now allocates new OID's when needed.
1638 Raw OID's may be specified in oid_getvalbyname.
1640 YAZ now uses GNU configure to generate Makefile(s).
1642 * Minor changes in some of the member names of DeleteResultSetRequest and
1643 DeleteResultSetResponse. See include/proto.h.
1645 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1646 and added member 'languages' in TargetInfo (which was missing).
1648 Changed the way attribute sets are handled in the retrieval
1649 module. These are now cached, just like the abstract syntaxes
1652 Changed YAZ so that it links with compiled ASN.1.
1654 Added Explain-schema definitions and mapping routines. The following
1655 Explain categories have been implemented: AttributeDetails,
1656 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1658 Fixed minor bug in Windows version of Server Library.
1660 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1662 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1664 Added EXTERNAL: UNIverse Resource Report (non-standard).
1666 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1667 ENUMERATED and SET OF.
1669 * Added 'const' to some of the char pointer arguments for the
1670 functions, data1_read_node, data1_getelementbytagname,
1671 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1674 Fixed bug in data1_insert_taggeddata - the last_child member of
1675 parent wasn't initialised.
1677 * Changed data1_read_record and data1_read_node so that the supplied
1678 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1679 doesn't refer to any parts of the "SGML"-buffer.
1681 Fixed bug in server library (Windows version of statserv_remove).
1683 * Changed code so that it compiles as C++. The type definition
1684 of Odr_fun which is a member of Odr_arm was changed. The result is,
1685 that an explicit typecast is needed for the fun pointer when
1686 using Odr_arm - as in:
1687 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1689 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1691 Implemented the new structured date and time definition as approved
1692 by the ZIG. Added schemaId element to the specificTag in Espec-1
1693 (also approved at the last ZIG). Thanks to RVDM.
1695 Added some Object identifiers (RVDM).
1697 Changed the Update Extended Service (RVDM).
1699 Added command "refid" to client which specifies referenceId for
1700 the following requests.
1702 Implemented extended service handling for server. See ztest.c
1703 for an example as well as backend.h. New handlers are registerd
1704 in the Init handler.
1706 * Changed interface for sort in server.
1708 Added new members to statserv_options_block. It allows a server
1709 to read options from another source than just the command line. Thanks
1710 to Charles Woodfield.
1712 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1713 renamed to zboolean. Some C++ compilers complained about the name.
1715 Minor changes to gils.abs. Added index 's' (sort) on title
1716 and date/time-last-modified.
1718 --- 1.4pl2 1998/1/30
1720 Fixed bug in server library regarding inetd mode (-i). This bug
1721 was introduced by release 1.4.
1723 --- 1.4pl1 1998/1/29
1725 Added sort facility in client and backend server interface.
1727 Fixed problem with dependencies in Makefile(s).
1729 Fixed bugs for encoders/decoders of extended services and
1732 Implemented sub-tree feature for schemas. Sub-trees are
1733 referenced in *.abs-files. See explain.abs for an example
1734 of the use of this feature.
1736 Modified bib1.att; local attributes for ANY didn't include
1737 ANY itself (only affects use of the retrieval module).
1739 Fixed bug in plain SGML reader in function data1_read_node:
1740 tags with prefix "var" was incorrectly interpreted as variants.
1742 Added feature "sub-schemas" to enable references to - and definitions
1743 of - group of elements.
1745 * Removed member parent from type data1_element (in data1.h).
1747 Implemented function odr_nullval() that returns the value of
1750 * Removed member num_children from data1_node (in data1.h).
1752 Made NT service interface part of the server library. The
1753 function statserv_main uses the NT service when required and
1754 calls the statserv_start / statserv_close routines.
1756 Routine zget_SearchRequest and zget_PresentRequest fills
1757 resultSetName/Id member with "default" instead of "Default".
1759 Fixed memory leak in server. Request queue member wasn't freed.
1761 Fixed nmem_exit so that memory is freed.
1765 Revised the CCL parser utility to be thread safe.
1767 Added function, oid_ent_to_oid, to replace the function
1768 oid_getoidbyent, which is not thread safe.
1770 * Added nmem_init and nmem_exit to initialize and release
1771 NMEM resources. Function nmem_init should be called once in the
1772 initial thread before NMEM/ODR is used. statserv.c and client.c
1773 have been changed accordingly. The change was necessary to make
1774 NMEM thread safe. The NMEM memory pool is shared amongst threads
1775 in a process. Unix-based applications will still work fine without
1778 Added NT Services interface for the the Z39.50 (statserv) Server.
1779 Refer to the ztest.c source on the usage.
1781 Windows 95/NT port using MSVC5.0. Project files are included in the
1784 * Defined new 'global' handle for the retrieval (data1) system. The
1785 new handled, data1_handle, describes the state of the data1 system.
1786 This handle is passed as first argument to virtually all
1787 data1 related routines. The functions data1_create and data1_destroy
1788 creates and destroys a data1 handle respectively.
1790 Added ODR encode stream member to all backend request structures
1791 init, search, scan etc. This stream should be used to allocate all
1792 memory used for the response when thread safe operation is needed.
1794 Changed the comstack utility, cs_addstr, to be thread safe. The
1795 returned hostname string returned by the function is now part the
1798 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1799 function. The cs_straddr takes a COMSTACK handle as argument, so this
1800 function must be used after cs_create and before bind/connect.
1801 This function is thread safe.
1803 Moved test server to 'ztest' directory - generic server code still
1804 in 'server' directory.
1806 Made prefix query (pquery.c) utility thread safe.
1808 Added new function modifier YAZ_EXPORT to 'export' public DLL
1809 functions when using windows (see include/yconfig.h).
1811 Added definitions to the OID database (util/oid.c) (RVDM).
1813 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1815 Added call to ccl_rpn_delete in client program.
1817 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1818 release of RPN structure.
1820 Added support for C++, headers uses extern "C" for public definitions.
1821 With input from RVDM.
1823 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1824 Thanks to Ronald van der Meer (RVDM).
1826 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1828 Added support for private extensions to the OID database
1829 (oid_setprivateoids()). Thanks to RVDM.
1831 Added optional, physical ANY (key replication)
1833 Fixed null-reference problem in GRS-1 output filter.
1835 Proximity operator added to Prefix Query Format (PQF).
1837 In test client command "base" accepts multiple databases.
1839 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1843 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1845 Smallish bug-fixes in the new encoders/decoders (explain).
1847 Bug fixed in DeleteRequest.
1849 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1851 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1853 Added SOIF syntax (using private OID for now) to retrieval module and client.
1855 Added Update extended service.
1857 Added SearchResult-1 additional info structure.
1859 Added optional CCL (ISO8777) interpreter as separate module. Available
1862 --- 1.2 1996/6/10 (1st anniversary release)
1864 Added Summary record syntax. Lightly tested.
1866 Added OPAC record syntax. Untested.
1868 Added ResourceReport service encoders/decoders. Untested.
1870 Fixed bug in z_Unit - wrong tagging on unitSystem.
1872 Fixed bug in the DiagRecs decoder.
1874 Added options for max PDU size and session timeout to frontend-server.
1876 Added documentation of query-language parsers and other supporting utilities.
1878 [frontend-server] Added Attribute set to the bend_scanrequest API.
1880 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1881 surrogate diagnostics were generated.
1883 [retrieval] Allow multiple local values for attribute.
1885 [retrieval] Allow multiple attributes per element in .abs files. index type.
1887 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1889 --- 1.1pl2 1996/4/10
1891 Minor changes, mostly specific to Zebra's requirements (retrieval)
1895 Repaired bug in frontend server when running multiple listening
1896 endpoints in dynamic mode.
1898 z_External() now won't break if a known, ASN.1 value comes encapsulated
1899 in an octet-string. The value will pass through unmodified in an Odr_oct.
1901 Added a bit of code to the demo client to decode & display
1902 ASN.1-structured records represented in the octet-aligned branch of
1903 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1905 Added z_ext_getentbyref() to the ASN module. Doc updated.
1907 * Completed the SCAN definition in the ASN module. This may break SCAN
1908 code based on older YAZ-versions at compile-time. The fix is easy -
1911 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1912 under the SCAN definition. Remember to initialize this, server-people.
1914 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1915 that this does not extend to ODR and ASN.
1917 Comstack allows insertion of established socket (primarily for
1918 inetd-operation of servers). Doc updated.
1920 Front-end server can now start from the inetd in TCP mode. Doc
1923 --- 1.0pl4 1996/1/24
1927 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1928 the rank and record number.
1930 Adjustments to the frontend server.
1932 Fixed diagnostic BER dumper. It ignored the file argument.
1936 Various changes to retrieval module.
1938 Changed the union discriminators of the protocol files from enums to
1939 ints paired with #defines.
1941 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1944 *Changed operator in the RPN structure to 'roperator', again to avoid a
1947 Fixed problems in Explain decoders/encoders.
1949 --- 1.0pl2 1995/12/6
1951 Memory bug in log module fixed.
1953 --- 1.0pl1 1995/12/5
1955 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1957 Bug in Explain DatabaseInfo module fixed.
1959 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1963 The shift to v1.0 signals that we now consider the *core* functionality
1964 of YAZ reasonably stable (the core being more or less equivalent to
1965 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1966 tested (Explain not at all - though that will happen soonish).
1968 Minor changes to code to support Windows port.
1970 Various minor changes after we're getting to use GRS-1 & co. more.
1972 Added Espec-1 format.
1974 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1975 of the protocol and it cannot be selected when encoding (maps into 'string'
1976 when decoding). Needed to talk to some servers.
1978 Demo client can request simple element set names.
1980 Added Diagnostic Format encoders/decoders.
1982 Added simple Close handling to frontend server (no hooks for resource
1983 reporting yet), and demonstration client.
1985 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1987 --- 1.0b3 1995/08/24
1989 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1990 handled incorrectly when records were requested in the searchResponse. This
1991 will only affect you if you use the frontend-server.
1993 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1994 Test-client will ask for and print GRS1. Ztest will return dummy records
1997 Added Explain encoders/decoders to the service-level API. Untested.
1999 Added Extended Services: Item Order encoders and decoders to the Service-
2000 level API. Untested. We could use a recent copy of the pertinent bits
2001 of the ILL protocol to add those bits.
2003 Added diagnostic format 1 encoders/decoders to the service-level API.
2006 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2007 odr_cons.c, which causes a more correct output.
2009 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2010 was always set to 0 when no records were requested in the searchRequest.
2012 * Added better external-handling. This shouldn't harm old code that
2013 *encodes* externals. It can break code that looks for a
2014 'single-ASN1-type' representation, since those types that are known
2015 are now decoded immediately. Look at the SUTRS sample code in
2016 seshigh.c and client.c. Documentation updated.
2018 Handling of structured records in bend_fetchresponse. Length -1 marks
2019 structured record, type is deduced from format field.
2021 --- 1.0b2 1995/06/27
2022 Fairly quick maintenance release to add SUTRS support.
2024 Fixed handling of SUTRS records in the demonstration client.
2026 * Added format field to the bend_fetchrequest and bend_fetchresponce
2027 structures of the backend API (frontend server). When the record is
2028 returned, the value of the format field is mapped to an OID. The
2029 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2030 of the record. The special value VAL_NONE in the bend_request means
2031 that no specific format was requested by the client. Documentation
2032 updated accordingly. Test server (ztest) will return a fixed dummy
2033 SUTRS record if your client requests SUTRS.
2035 Documentation updated accordingly.
2037 You can now set external libraries and RANLIB support in the top-level
2041 First public release.
