1 Fixed bug #830: pkg-config support.
5 Extended ZOOM result set options with two options that may be read by
6 a client: resultSetStatus and presentStatus with values as specified for
8 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
10 Fixed bug #827: Using SSL fails on Debian etch.
12 Fixed bug #826: Weird looking chars for set of MARC records.
14 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
15 that is treated as an ItemOrder with itemRequest being an XML document
16 external. The value of "doc" is the content.
18 Extended the GFS search facility. New member of bend_search_rr
19 'estimated_hit_count' signals that hits is known to be an estmate
20 (higher or lower than real hit count). New member 'partial_resultset'
21 signals that the search was partial (hit count is lower or equal than
22 real hit count). For Z39.50, the information is stored in resultSetStatus
23 member of SearchResponse APDU. For SRU, the information is signalled
24 via SRU diagnostic 59: "Result set created with valid partial results
27 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
31 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
33 Added ZOOM_connection_peek_event.
35 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
36 the following new functions:
37 ZOOM_event_nonblock, ZOOM_connection_process,
38 ZOOM_connection_get_{socket,mask,timeout},
39 ZOOM_connection_fire_event_{timeout,socket}.
40 The existing blocking event handler, ZOOM_event, is a wrapper for the
41 + blocking ZOOM_event_sys_{poll,select}.
43 Implemented function ccl_xml_config which parses XML version of CCL
44 configuration (bug #798).
46 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
48 Added timings utility (yaz/timing.h)
52 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
55 Fixed bug #779: Rotation of apdu.log fails.
57 Fixed for character set conversions:
58 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
59 Honor G1 set in MARC-8 decoding.
63 Fixed bug #775: char conversion does not handle Alternative UTF-8
66 Implemented function yaz_marc_read_line which parses MARC line format
67 records. There is a wealth of formats out there. So far, this function
68 reads line records produced by yaz_marc_write_line.
70 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
71 more generic and easier to remember(!) options: -i format and -o format
72 which specifies input format and output format respectively - where
73 format is one of "marc", "marcxml", "line", "marcxchange".
75 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
76 does not print anything except warnings for records.
78 For yaz-marcdump, added support for MARC split into files (-s) with a given
81 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
82 spec, at http://www.loc.gov/standards/sru/record-update/
83 This has changed the binary layout of the following structs:
84 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
85 bend_update_rr . Patch by Ko van der Sloot.
87 Added GFS utility function bend_assoc_is_alive which returns 1 if
88 association is still alive (client is connected); 0 otherwise (client
89 closed connection). This allows busy servers to stop working for
92 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
93 been a separate piece of software. This version of ziffy has been modified
94 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
96 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
98 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
99 Client code may now interrogate options such as "init_opt_sort" to
100 find out whether the server claims to support various options.
102 --- 2.1.40 2006/11/27
104 Added utilities yaz_{set,get}_esn to set/get element set name from
107 Removed the build of libyazthread.la. The libyaz.so is the threaded version
108 of YAZ and has been so since YAZ 2.1.10.
110 Implemented ZOOM_record_error which returns error information for
111 record (surrogate diagnostic).
113 --- 2.1.38 2006/10/31
115 Updates for SRU Update by Ko van der Sloot:
116 1. Changed name from "operation" to "action"
117 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
118 versions in the code, marked as 'backward compatible'.
119 3. Added diagnostics for SRU Update.
121 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
123 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
125 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
127 For GFS, fixed problem with SRU diagnostic 'First record position out of
128 range' being issued for 0 hits.
130 zoomtst10 part of Windows Build.
132 --- 2.1.36 2006/10/13
134 Implemented yaz_filepath_comp which splits a path into file path
135 components (required by Zebra 2.0.3+).
137 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
138 BSD inspired license until now so this should not have any real impact on
139 anybody. See http://www.opensource.org/licenses/bsd-license.php
141 Fixed bug #687: Missing log lines.
143 Fixed bug #678: CQL to PQF translation does not preserve double-quote
146 Fixed bug #689: SRU diagnostics to be added.
148 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
149 whether a connection is idle (no more work do do).
151 --- 2.1.34 2006/10/04
153 Change type of optval from long to int for invocation of setsockopt with
154 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
156 Added support for specifying the max log file size for the Generic
157 Frontend Server. The size is given with option -r.
159 --- 2.1.32 2006/09/21
161 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
163 --- 2.1.30 2006/09/17
165 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
168 Fixed bug in Generic Frontend Server that could cause a server to stop
169 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
171 For the generic frontend server, the maximum record size is used as maximum
172 size of incoming packages (SRU + Z39.50). The value until was previously
173 only used in Z39.50 Init negotiation and, later, in a session controlled
174 sizes of records returned. This is controlled using -k option. It can be
175 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
177 --- 2.1.28 2006/09/04
179 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
182 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
184 New option for yaz-marcdump -lpos=value which allows setting a portion
185 of MARC header to a certain value.
187 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
189 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
190 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
192 --- 2.1.26 2006/08/15
194 Fixed problem with SRU mode type (soap, get, post) for yaz-client
197 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
199 --- 2.1.24 2006/08/08
201 Fixed MARC ISO2709 encoding routines to deal with character set
204 Minor changes to GFS logging. Database included in search request log
207 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
208 cached/multiple records.
210 Shared libraries are built by default on Unix+configure.
212 Changed cql2pqf transformation to use a different evaluation order. The
213 new order is: always, relation, structure, position, truncation, index
214 and relationModifier. Old order was: always, relation, relationModifier,
215 structure, index, position, truncation. Note that the the latter ones
216 override former ones for identical attributes.. The new scheme means that
217 it is possible to override any existing attribute with a relationModifier.
218 And also that it is possible to override everything for the index rule
219 (except the ones listed in relationModifier). No order is perfect but this
220 one, we believe, covers more real cases.. The "always" should have been
221 called "default", since the attributes there can be overridden with all
224 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
225 compilation phase, but also for yaz-config --cflags output. This allows
226 us to have public headers with Libxml2 stuff in them . It should also,
227 eventually, make Libxml2 checks redundant in packages using YAZ, such
230 --- 2.1.22 2006/06/15
232 Changed SRU update structure bend_update_rr so that SRU diagnostics are
233 stored in uri, message and details.. Previously diagnostics were stored
234 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
235 compatibility.. but he's probably the only one affected, so.
237 Added support for CCL, compiled on the client side, in ZOOM-C. This
238 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
239 input; the resulting query objects can be used for for searching with
240 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
242 YAZ' configure searches for OpenSSL by default.
244 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
245 SL_CTX_use_certificate_file. See
246 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
247 for more info. Thanks to Ko van der Sloot.
249 --- 2.1.20 2006/06/02
251 Bug #600: SRU GET, POST support for yaz-client. Introduced
252 command 'sru' which selects method SOAP/GET/POST.
254 Allow missingValueAction to be specified for the sortspec string -
255 function yaz_sort_spec. By default, the missing value action is null.
256 Use ! to specify "abort". Use = followed by stringvalue to specify default
259 Ensured that Present-handler (if defined) is called in GFS before any call to
260 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
261 searchRetrieve requests.
263 Documentation for YAZ is now based on the Docbook XML/XSLT using
264 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
265 is no longer depending on jade/openjade or docbook-to-man scripts.
266 PDF is no longer part of the distribution - but can optionally be
267 made using DSSSL/jadetex or FOP.
269 Added retrieval handling support in Generic Frontend Server to support
270 conversion between MARC/XML as well as XSLTtransforms. See
271 etc/yazgfs.xml for an example.
273 Added Authentication support to Generic Frontend Server in SRU
274 mode. Authentication using HTTP Basic is supported, as is the use
275 of 'x-username' and 'x-password' parameters in the request itself.
277 Added support for a new character set MARC8s identical to MARC8 except
278 that it converts combined characters to single Unicode characters in the
279 Latin-1 range (when possible).
281 --- 2.1.18 2006/04/24
283 ASN.1 compiler 0.4: generates brief Doxygen file header for
284 generated .h/.c files.
286 Utility yaz_iconv now supports conversion to MARC-8.
288 New facilities for the MARC module. The reading - and writing of
289 content are separate methods for the yaz_marc_t handle. The following
290 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
291 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
292 format). Write functions have prefix yaz_marc_write_.. The existing
293 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
294 available. Removed support for OAI-MARC and simplexml (not the
295 simplexml from PHP5).
297 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
298 to be returned for this connection.
300 --- 2.1.16 2006/03/31
302 Allow multiple languages and charsets to be specified with
303 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
304 negcharset iso-8859-1,utf-8
306 Translation of proximity nodes from CQL into PQF now works.
308 Moved to automake 1.8, 1.9.
310 Added function yaz_log_set_handler which allows a log handler to be
311 installed. This handler will be called for all log messages. Output
312 to file is also produced; but that can be disabled by passing NULL
313 fname to yaz_log_init_file.
315 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
317 For SRW (including GFS), accept application/soap+xml as content-type
320 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
321 produces NO stylesheet reference even if a default stylesheet is specified
324 --- 2.1.14 2006/03/14
326 Updated Windows package to include yazd.dll + yazd.lib for the
327 Development component.
329 If the environment variable YAZ_LOG is set, then it is used as a
330 string indicating the default level of logging to use if not
331 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
332 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
333 used as before. So, for example, to omit warnings from YAZ logging,
336 cql_transform() now map structure and other attributes before indexes,
337 so that index-specific structures and other attributes can override
338 defaults. So now a combination of mapping specifications such as:
340 index.dc.date = 1=date-modified 4=5
341 does the right thing.
343 cql_transform() now also respects the "always" mapping specification,
344 which establishes an initial set of attributes to be used for all
345 terms except where overridden by more specific attributes associated
346 with the index, relation or modifier.
348 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
349 which mode to use; one of "post", "get" or "soap" (SRW, default).
351 Fixes for yaz_iconv routines: changed trie-based character set conversions
352 to use only non-negative values for bit fields due to Sun's C compiler not
353 supporting negative values.
355 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
356 sequences where not read correctly. Fix by Rustam Usmanov.
358 Updated win/makefile to use options, settings which makes things
359 compile with VS C 2005.
361 --- 2.1.12 2006/02/01
363 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
365 In ZOOM socket code, use select instead of poll on MacOSX.
367 ZOOM-C now support client-side compilation of CQL into RPN that is
368 sent to the server, enabling CQL to be used against all Z39.50
369 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
370 ZOOM_query object, and submit it using ZOOM_connection_search().
371 The CQL-to-RPN translation uses a configuration file, the name of
372 which must be specified in the Connection's "cqlfile" option.
374 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
375 function, which takes as its start-term parameter a ZOOM_query object
376 (which may have had either CQL or RPN set into it).
379 --- 2.1.10 2005/11/29
381 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
382 GFS to support this as well. Backend handler, bend_srw_update, does the
383 update work. Code contributed by Ko van der Sloot.
385 Allow retrieval of Search Result-1 information in ZOOM by the use of
386 options that are attached to a result set. ZOOM documentation updated
389 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
390 UTF-8 conversion. Patch by Raj Patel.
392 Added option -m to GFS to control formatting of timestamps in log file.
394 Added 'exit' as synonym for 'quit' in yaz-client
396 Added support for specifying SRW resultSetId + resultSetIdleTime in a
397 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
398 for the new members. Patch by Ko van der Sloot.
400 Added support for SRU POST. It is supported for content-type
401 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
403 Do not build the separate Multi-threaded (MT) library libyazthread.la.
404 Instead make the library libyaz.la multi-threaded. Threading as a whole
405 can still be disabled by configure option --disable-threads. Previosly,
406 with older GLIBCs there were problems with MT libs under Apache. This
407 has now been fixed a long time ago.
409 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
412 CQL module modified to be case insensitive for relations/indexes/operations.
414 Fixed bug in CQL transform code: incorrect value relationModifieder
417 Added 'show all' command for yaz-client which retrieves all results
420 Added new yaz-client, xmles, which takes a (private) OID and
421 a document to be sent as an extended service request.
423 Describe new yaz-client commands wait_response and set_auto_wait.
425 Increase TCP/IP listener backlog from 3 (which I am guessing was
426 copied from the SunOS manual entry way back when) so SOMAXCONN, so
427 that the socket will queue as many incoming connections as it's able
428 to handle ongoing connections. In other words, it will never now
429 refuse a connection that it would be able to handle merely because
430 it's not got around to accepting() enough of the pending connections
431 yet. This is the behaviour anyway under Linux, where the listen()
432 argument is ignored; but not under BSD and on systems such as
433 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
434 YAZ-based servers should now be uniform across operating systems in
437 yaz-marcdump uses 64-bit file access on some systems. This is enabled
438 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
439 This allows yaz-marcdump to read large MARC batches (>2 GB).
441 Modified all YAZ source files - except the source which is auto-generated
442 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
445 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
446 corresponding to the existing *_setl() function. These allow option
447 values containing arbitrary valuues.
449 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
450 ZOOM_resultset_sort() in new applications. Its behaviour is identical
451 except that it returns an indicator of whether or not the sort
452 criterion was accepted (0 for OK, -1 for invalid).
456 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
457 MARC output rather than returning "new" buffer.
459 yaz-client warns about unknown init options.
461 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
465 Added support for SRW sort in Generic Frontend Server. Patch
466 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
467 sortKeys - or NULL if none is provided.
469 Fixed bug #307: It was impossible to specify indefinite/no timeout
470 for ZOOM_event. Special timeout value -1 now means indefinite timeout
473 Added support for multiple languages and charsets to be specified in
474 ZOOM. Each charset/language is separated by a blank. If negotiation is
475 in effect in init-response, Option
476 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
477 Code based on patch by Vasiliy Osadchuk.
479 Fixed bug #306: infinite recursion that occurred when calling
480 yaz_log_level_init as the first call (before other log level or
483 Fixed bug in scan handling in front end server: if preferred-Position-In-
484 Response was non-present, a NULL pointer referece was performed.
488 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
489 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
490 now defined for all those error codes. So instead of putting 109 in
491 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
492 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
494 Modified the yaz-marcdump utility to skip garbage bytes between MARC
497 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
499 Program yaz-client now exits and produces an error message if multiple
500 Z39.50 servers are specified on the command line (none or one allowed
503 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
508 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
510 Fixed bug #272: Preserve spacing for CCL terms.
514 Added support for virtual hosts and multiple backend servers for
515 the YAZ frontend server. The configution is XML based and
516 support specificition of CQL to RPN mappings and explain information.
517 See section "Virtual Hosts" in the YAZ manual.
519 Extended OPAC display utility. OPAC display utility renders
520 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
521 to supplement yaz_marc_decode_wrbuf.
523 Fixed a bug in MARC decoder that could caused it to crash for some
524 invalid MARC records. More diagnostics and warnings where added in
525 XML output (warnings, etc are stored in comments).
527 --- 2.0.34 2005/02/08
529 Fixes for UNIX domain sockets. Bug #261.
531 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
533 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
534 Added yaz_marc_subfield_str which defines subfield lead string which is
535 used in YAZ_MARC_LINE format. Default string is blank+$. Added
536 yaz_marc_endline_str which defines end of fields string used in
537 YAZ_MARC_LINE format. Default string is newline.
539 Experimental support for MarcXChange. This format can be produced
540 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
541 http://www.bs.dk/standards/MarcXchange.xsd
543 Added yaz-client commands scansize that sets maximum number of
544 entries to be returned by scan.
546 --- 2.0.32 2005/01/11
548 Added support for SRW scan in yaz-client and Generic Frontend Server.
550 * Added whereInList member to SRW Scan Term.
552 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
554 Fixed NMEM system to return aligned blocks on the smallest boundaries
555 that are suitably aligned for all possible types on the particular
556 architecture YAZ is being built for.
558 --- 2.0.30 2005/01/04
560 Fixed numerious warnings that was issued with newer versions of GCC.
562 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
563 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
566 Make YAZ Generic Frontend Server slightly faster.
568 Enhance (and reduce) logging for Generic Frontend Server.
570 Revert YAZ log system so that it flushes every write operation
571 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
573 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
574 instead of LOG_, due to name clash with syslog(3). LOG_ are still
575 present. New applications should define YAZ_USE_NEW_LOG=1 - this
576 will effectively disable old definitions.
578 --- 2.0.28 2004/11/09
580 Added yaz_log_time_format which specifies log format using
583 Added yaz_log_module_level which returns mask for a module. Value
584 is non-zero mask a if module is enabled; zero if disabled.
586 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
587 in include/yaz/cql.h.
589 Fixed bug #176: Dont throw diagnostics on empty SRU args.
591 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
593 Fixed bug #172: RPM builds does not enable SSL.
595 Doxyfile.in part of dist. Doxyfile generated by configure.
597 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
598 are given and the corresponding component does not exist.
600 Extend CCL documentation in YAZ reference. Describe r=r.
602 --- 2.0.26 2004/10/01
604 Fixed MARC->MARCXML conversion to properly deal with
605 fields, subfields, indicators having non-ASCII characters.
607 Fixed MARC->MARCXML conversion so that ASCII control characters
608 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
611 Added YAZ GFS support for conversion from Z39.50 surrogate
612 diagnostics to SRW surrogate diagnostics.
614 Bug fix: YAZ GFS did not return schema in explainResponse.
616 --- 2.0.25 2004/09/30
618 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
619 now converts recordSchema to elementSetName as well as schema URI.
621 Fixed bug in COMSTACK that prevented HTTP request packages from being
624 --- 2.0.24 2004/09/29
626 Added CCL facility r=r "range" which is similar to r=o "ordered" but
627 does not require white-space before and after the dash in a range, e.g.
628 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
631 Fixed a few AC_TRY_LINK configure tests that did not operate properly
632 due to new GCC removing "redundant" code.
634 Added yaz-client commands scanpos and scanstep that sets preferred
635 position and step-size for scan.
637 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
639 Added CCL utility ccl_qual_buf which parses one or more CCL
640 spec lines in a buffer.
642 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
643 of name and value - ignoring empty lines and comments.
645 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
647 Added odr_get_element_path which returns current element path for an
648 ODR handle. This utility is useful in error handling or user-defined
651 Added ODR_PRINT utility odr_set_stream which is is a more generic
652 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
653 to a write function and pointer to close function. The close function - if
654 non-NULL - will be called during odr_destroy.
656 Fixed bug in CCL parser where truncation char was not removed from
657 right side when truncation=both was in effect.
659 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
662 --- 2.0.23 2004/08/11
664 Fix buffer overrun in CQL parser when dealing with proximity (%).
666 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
667 to UTF-8/UCS conversion is now only based on codetables.xml.
669 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
671 --- 2.0.22 2004/08/06
673 Add support for more "commit changes" in ZOOM (uses Extended Services).
675 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
678 Yet another small fix for configure of SSL.
680 --- 2.0.21 2004/05/14
682 Fix SSL libs for configure when --with-openssl=DIR is given.
684 --- 2.0.20 2004/05/10
686 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
688 SSL comstack now uses yaz.pem certificate file on server side
689 by default. Certificate filename can be configured by calling
690 comstack function cs_set_ssl_certificate_file before cs_bind is used.
692 Fix bug regarding multiple calls to ZOOM_connection_connect.
694 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
696 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
697 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
699 ZOOM now allows inspection of X509 peer certificate for verification.
700 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
702 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
703 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
704 as "modular" but it simplifies things.
706 Added cs_get_peer_certificate to that returns peer X509 PEM.
708 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
709 NULL if SSL is unavailable.
711 Documentation about MARC decoding tools.
713 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
715 --- 2.0.19 2004/03/30
717 Rename CHANGELOG to NEWS to follow GNU style packing.
719 Fix bug with missing initialization of member in init_diagnostics.
720 This bug affects threaded version of GFS server.
722 --- 2.0.18 2004/03/20
724 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
727 Ensure zlib.dll is packed with Windows install.
729 --- 2.0.17 2004/03/17
731 Fix encoding of xsd:string to use text instead of CDATA.
733 Fix endless loop in CQL parser with unbalanced ".
735 Use a more compact way to store MARC-8 conversion tables.
737 --- 2.0.16 2004/03/16 Debian only
739 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
742 Update CQL parser to use new CQL 1.1 modifiers for booleans and
747 --- 2.0.15 2004/03/01
749 Another fix for decoding of XML packed records.
751 --- 2.0.14 2004/02/25
753 Fixes for Chunked encoding. White space not ignored after length spec.
755 Update NS and use default NS for SRW diagnostic elements.
757 --- 2.0.13 2004/02/23
759 Implement ZOOM_resultset_cache_reset which resets record cache.
761 Implement ZOOM_resultset_sort which sorts a result set.
763 Implement chunked HTTP transfer.
765 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
767 --- 2.0.12 2004/02/16
769 Added member 'schema' to bend_explain_rr structure so that backend
770 can specify explain record identifier. Defaults to Zeerex 2.0.
772 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
774 --- 2.0.11 2004/02/16
776 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
779 Added init command for yaz-client which sends "extra" init request.
781 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
782 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
784 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
786 Make ZOOM error code for "invalid query".
788 Fixed compilation for SSL which wasn't properly enabled for all platforms.
790 --- 2.0.10 2004/02/05
792 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
795 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
797 Added option -p <file> to make Generic Frontend Server to write PID file.
799 Added option -D to put Generic Frontend Server in background on its own.
801 Make ZOOM C recognize option "password". If unset, "pass" is used
802 (for backwards compatibility).
804 Fixed a bug in Generic Frontend Server that could make it crash if a
805 client sets characterSetNegotation bit, but didn't pass negotiation stuff
808 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
809 Must be issued before open, in order to be in effect.
811 --- 2.0.9-6 2004/01/12 Debian/Windows
813 Make the SRU server more picky WRT unknown params, etc.
815 Bug fix: ZOOM scan response didn't return displayTerm - when present.
817 New YAZ client command, options, that sets Z39.50 options.
819 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
820 options from a string of tokens (one token for each option bit).
822 Update SRW diagnostic code messages.
824 --- 2.0.9-5 2004/01/07 Debian/Windows
826 Handle user defined stylesheet for SRW/SRU.
828 --- 2.0.9-4 2004/01/06 Debian/Windows
830 Fix bug in decoding of Content-Length.
832 --- 2.0.9-3 2004/01/06 Debian/Windows
834 Fix a bug with decoding of XML packed records.
836 --- 2.0.9-2 2004/01/05 Debian only
838 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
840 Fix bug in SRW/SRU diagnostics decoding.
844 Fixed bug in Generic Frontend Server which could drop records exceeding
845 preferred message size. Reported and fixed by Irina Dijour.
847 Fixed calculation of package size for structured records in Generic
848 Frontend Server. Reported and fixed by Irina Dijour.
850 Fixed namespace for SRW/SRU diagnostics.
852 Fixed SEGV in yaz-client that occured for HTTP connection errors.
856 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
857 this version is incompatible with version 1.0 and older YAZ SRW/SRU
860 CQL changes to reflect recent changes to the specification:
861 * Documentation talks about context sets instead of index sets.
862 * Documentation talks about indexes instead of qualifiers.
863 * The CQL-to-PQF transformer's configuration file now uses
864 "index.set.name = <attributes>" instead of the old form
865 "qualifier.set.name = <attributes>". (Both forms are still
866 understood but the latter is deprecated.)
867 * CQL terms with no explicit index specified are now interpreted as
868 cql.serverChoice instead of srw.serverChoice (which of course
869 behaves exactly the same.)
873 MARC conversion can now generate ISO2709 output in another
874 character set. yaz-marcdump uses this facility if you invoke it
877 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
878 functions from there can be used from C++.
882 Frontend server now transfers memory from decoded packages to stream
885 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
886 references to show up.
888 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
889 the ZOOM Abstract API. The older names for the same options are still
890 also supported for the benefit of old applications.
892 ZOOM-C supports "implementationId" and "implementationVersion" options
893 to go along with "implementationName". These allow the user code to
894 specify identification strings to be sent to servers.
895 Add OID for the new ExtLite attribute set.
897 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
898 as requested/supplid by Ere Maijala <ere@atp.fi>
900 For generic frontend server, reverse the order of
901 "toolkit-supplied / application-supplied" strings sent as implementationId,
902 Name and Version. Also, remove the spaces around the slash. This brings
903 the GFS in line with the behaviour of ZOOM-C on the client side.
905 Add function ZOOM_scanset_display_term.
907 yaz-client shows scan displayTerm if present.
909 Utility yaz-iconv is now installed by default along with the man page
912 Extend configure check for OpenSSL to use pkg-config where available (such
915 Incorporate patch by Morten Bogeskov which allows a Unix file socket
916 server to specify uid/gid/mask for socket using the format
917 unix:[user=uid,][group=gid,][umask=mask,]file=path
918 If file= is omitted the existing format is assumed, e.g.
920 in which case the mask is 0666 (rw for everybody).
922 Major restructure of YAZ source. All source in libyaz is in src directory.
923 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
924 util (utility programs such as ASN.1 compiler, yaz-marcdump).
926 Added man page for utility yaz-marcdump (used to be called marcdump).
927 yaz-marcdump is installed by 'make install'.
929 Fixed a memory leak in Generic Frontend Server that occurred when decoding
930 of incoming package failed.
932 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
934 Change prototype of odr_perror: add const to message string.
936 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
938 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
939 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
940 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
941 DNS lookup. There should not be any compatibility problems with this
942 assuming that blocking=1 or 0 is used.
944 Fix bad reference in UNIX comstack in function cs_addrstr.
946 Fix for compilation on AIX.
948 The generic front-end server (server/seshigh.c) now supports returning
949 Init diagnostics to the client in User-information-field, in
950 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
955 Allow any CQL relation (not just all,any,exact,scr).
957 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
958 that features the same UI.
960 Implemented command update0 in YAZ client which is equivalent to
961 update but uses old of Ext Update ASN.1.
963 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
964 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
965 Previously no OID was used for this info.
967 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
968 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
969 returns 'malformed search term' otherwise.
971 SortResponse member resultCount now set to NULL in sort handler of
974 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
977 Add three new utility functions for translating OIDs between various
978 formats -- symbolic name such as "Usmarc", minus-1-terminated int
979 arrays and dotted strings such as "1.2.840.10003.9.5.1":
980 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
981 char *oid_to_dotstring(const int *oid, char *oidbuf);
982 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
984 Reverted modifications for ES Update definition for z_IU0Update
985 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
986 is back to YAZ 2.0.2.
988 String value attributes for CCL parser.
990 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
991 which their FirstSearch server returns in Init responses, sometimes
992 carrying useful diagnostic information when Init fails. This has the
993 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
994 "z39.50/oclcui.asn", where its definition is somewhat different from
995 what OCLC document on their web-site, as required to interoperate with
998 Support for anonymous authentication in yaz-client. Use the command
1001 * Fix the OID of the Index Data-local "admin" Extended Service from
1002 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1003 the 1000, which indicates a locally-defined OID, was a mistake.
1005 --- 2.0.3 2003/06/20
1007 Fix CCL directive @case handling so that it affects string match for
1008 both CCL keywords and qualifiers.
1010 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1011 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1012 Decoder has been updated with ASN.1 changes as listed in
1013 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1014 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1015 z_IUUpdate, remains unchanged.
1017 ZOOM_record_get may now return a record in a specific character set.
1018 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1019 "from" is the character set of record as returned by target. "to" is
1020 the character set to be returned. If omitted, "to" is UTF-8.
1022 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1024 New ODR utility, odr_getelement, which returns name of element for
1025 which encoding/decoding failed.
1027 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1028 in cases where a required element was omitted.
1030 Bug fix: some MARC8 sequences were not converted.
1032 New ZOOM option "step" which specifies number of records to be
1033 retrieved in one chunk. Used in conjunction with "start" and "count".
1035 SRW support for yaz-client. Use scheme http: to use it, e.g.
1038 yaz-client no longer does (un)intelligent character set conversions
1039 by default. Can be enabled with charset and marc_charset commands.
1041 xmalloc trace fix for 64-bit systems such as DEC alpha.
1043 Solaris 2.6 compile fix.
1045 New function, cql_strerror() translates SRW error codes, as returned
1046 by cql_transform_error(), into human-readable English strings. Used
1047 in yaz-client diagnostics when appropriate.
1049 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1050 converts it into a type-1 query which is sent to the server. This
1051 makes CQL available for use with all Z-servers, as opposed to the tiny
1052 minority that can handle CQL queries themselves.
1054 --- 2.0.2 2003/04/28
1056 New Debian package layout similar to the Redhat Package layout.
1058 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1059 and search result respectively.
1061 --- 2.0.1 2003/04/25
1063 Redhat package is now several packages: libyaz (runtime libraries),
1064 libyaz-devel (development and documentation, and yaz (utility programs).
1065 Package spec file by Morten Bøgeskov.
1067 New member 'schema' in struct bend_fetch_rr which the name of requested
1068 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1069 handler MAY set this to reflect the schema of the returned record.
1071 New member 'display_term' in struct scan_entry. GFS now sets member entries
1072 and allocates scan entries to be filled by user scan handler. In previous
1073 version, entries member was allocated by the scan handler. That still works,
1074 but the GFS will ignore member display_term - assuming it was NOT set by
1075 the handler. The fact that the GFS now allocates the entries both allows
1076 for new members and makes a scan handler easier to write.
1078 Fix CQL lex buffer overflow.
1080 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1081 SRU default recordPacking is string.
1083 SRU protocol support for frontend server.
1085 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1087 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1089 Added scan for the ZOOM shell (zoomsh).
1093 * String Identifers for Schemas (Amendment 5).
1094 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1095 Old definition for schema
1096 Odr_oid *schema; /* OPT */
1101 Z_InternationalString *uri;
1102 #define Z_Schema_oid 1
1103 #define Z_Schema_uri 2
1106 * resultCount parameter to Sort Response (Amendment 1).
1107 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1109 Support for SRW 1.0 over HTTP. This is an optional feature and
1110 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1113 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1114 on the same port. SRW SearchRetrieveRequests are mapped
1115 to bend_init,bend_search,bend_fetch,bend_close.
1117 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1119 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1120 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1122 ZOOM connections are SRW based if schem http is used for hostname
1123 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1124 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1126 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1127 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1128 distance=n, order=true/false, relation=le, prox unit=word. If
1129 n is omitted, distance 1 is used.
1131 Fixed problem with C compiler include path in wrong order.
1133 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1134 on Solaris. Patch from Ko van der Sloot.
1136 New MARC decode API. All new functions operate on a yaz_marc_t
1137 handle. The most important new functions are: yaz_marc_create,
1138 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1139 decode and destroy respectively. Decoder can produce formats
1140 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1141 include/yaz/marcdisp.h.
1143 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1144 to UTF-8, UCS-32, wchar_t or Latin-1.
1146 * Prototypes for yaz_iconv_-functions moved to separate header
1147 include/yaz/yaz-iconv.h.
1149 Make a few private functions 'static' in unix.c. This prevents
1150 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1152 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1153 are set when Init Response is received.
1155 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1156 but returns diagnostic set as well.
1158 New function yaz_strerror which is a portable wrapper for
1159 strerror/strerror_r/GetLastMessage.
1161 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1162 is returned for MARC. If type is "oai", then OAI MARC is returned.
1164 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1167 --- 1.9.2 2002/11/26
1169 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1171 Fix bad race conditions on SIGTERM and terminate gracefully in
1174 Move retrieval (data1) module to Zebra since nobody seems to be
1177 Add GRS-1 render for ZOOM using same format as yaz-client.
1179 --- 1.9.1 2002/10/05
1181 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1183 Fix broken ESpec handling in data1 module.
1185 SGML reader parses comments and makes them part of the data1 tree.
1187 Added several type casts so that YAZ compiles as C++ code.
1189 ZOOM didn't handle PDU encoding failures properly.
1191 Added more Bib-1 diagnostics (approved extensions).
1193 GNU configure: better check for iconv.
1195 More portable use of accept, getpeername. Check for socklen_t. Use
1196 int/size_t if socklen_t is not defined.
1200 PQF parser rejects bad queries - including those with extra
1201 characters in them. PQF parser used to silently ignore that.
1202 Cleaner API for PQF added, which allows you to get detailed
1203 error information for bad queries (see yaz/pquery.h).
1205 Fixed bug in ZOOM_record_get for type "database".
1207 Implemented mini iconv library supporting conversions between
1208 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1210 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1212 --- 1.8.9 2002/08/20
1214 Fixed ZOOM C record cache so that preferredRecordSyntax and
1215 elementSetName is used to check for already fetched records.
1217 --- 1.8.8 2002/08/02
1219 Added three members in bend_initrequest structure to facilitate
1220 character set negotiation.
1222 Fixed a bug in frontend server that could cause indefinite
1223 loops under rare conditions.
1225 Revised character set utilities (charneg.h) so that encoding
1226 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1228 For PQF, directive @term <type> sets term type for Scan/Search.
1229 Here <type> is general, string, numeric, null. The term type
1230 is inherited - just like @attr.
1232 New call odr_set_charset that sets character set conversion for
1233 international-strings on a ODR stream. Prototype is:
1234 int odr_set_charset(ODR o, const char *to, const char *from);
1235 The InternationalString is still represented as C string in YAZ
1236 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1237 won't). On the protocol level, you can use any encoding.
1239 Support for UNIX sockets in ZOOM.
1241 Solaris recv sometimes returns errno == ENOENT. It is treated as
1242 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1244 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1245 both client and server. Code by Morten Bøgeskov.
1247 --- 1.8.7 2002/05/22
1249 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1250 that they can be used directly from Visual Basic. You must recompile
1251 your windows APP if you're using ZOOM.
1253 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1254 Commands "lang" and "charset" sets language and character set respectively.
1255 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1256 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1258 Attributes from multiple CCL fields may be OR'ed rather than merged
1259 using directive "@field or". Fields are still merged by default -
1260 equivalent to "@field merge".
1262 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1265 Fixed bug in zget for parameter ExtendedServicesResponse.
1269 --- 1.8.6 2002/03/25
1271 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1273 Client displays USR.1:SearchResult-1 (hits per term).
1275 Additional Search Info for search in Generic Frontend Server.
1277 Fixed CCL parsing of "field=s".
1279 WIN32 installer - using the excellent NSIS software from nullsoft.
1281 Fixed CCL parsing of "field = - <number>".
1283 Added function yaz_marc_decode that decodes MARC for line mode
1284 display or XML (similar to that used by JZKit).
1286 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1287 Z39.50. But ISO/ILL was, however.
1289 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1290 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1295 --- 1.8.5 2002/02/03
1297 New YAZ client features: Command completion and new commands:
1298 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1299 Code provided by Jacob Poulsen.
1301 New call oid_trav, that visits all registered OIDs via callback.
1303 Function ZOOM_record_get now returns const char pointer rather than
1304 void pointer. It saves a lot of type casts.
1306 For YAZ client, command "auth" now allows you to set authentication
1307 in IdPass style. It is enabled when three tokens are given - order
1308 is user, group and password.
1310 Fix memory leaks in MARC record handling for ZOOM.
1312 New option for YAZ client, -k <kilobytes> that sets
1313 maximum record size. Similar to -k option for generic frontend
1314 server and yaz-ztest.
1316 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1318 Prefix query parser reports "fail" when bad attribute set is given.
1320 Fix in MARC decoder. Proximity logging. Fix for attribute set
1321 in scan handler for server. Patches by Shigeru Ishida.
1323 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1326 Configure option --with-openssl=<dir> now works when a directory is
1327 specified. Patch provided by Morten Bøgeskov.
1329 New option for YAZ client, -u <auth>, that sets authentication.
1331 ZOOM fix: error information was sometimes "missing", since error
1332 was cleared/reset too when it shouldn't.
1334 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1336 --- 1.8.4 2002/01/04
1338 Scan for ZOOM API. New object ZOOM_scanset. New functions
1339 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1340 ZOOM_scanset_destroy.
1342 New ZOOM function, ZOOM_connection_last_event, that returns type
1343 of last event (such as "receive data", "send data", "apdu received",
1346 New ZOOM option, schema, that specifies schema for retrieval.
1348 New CCL feature. Qualifiers can be aliases for one or more
1349 other qualifiers (if more than one is given, OR is used).
1351 ZOOM uses named result sets if target supports it.
1353 Two new YAZ client commands: . (dot, which sources a script of YAZ
1354 client commands), and ! (to execute shell command.). Implemented
1357 Working on Debian packages.
1359 --- 1.8.3 2001/11/19
1361 YAZ client enables named result sets only if target supports it.
1363 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1365 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1366 with key="host" to get same result.
1368 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1369 Function Z3950_resultset_record(s) returns references to records
1370 "owned" by resultset. To become owner use Z3950_record_clone.
1372 Function z_ext_record handles Extended Services. Thanks to
1375 --- 1.8.2 2001/11/12
1377 CCL Parser fix: ignore token comma when dealing with and-lists.
1379 Documentation updates for COMSTACK.
1381 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1382 Changed prototype Z3950_records. For some functions, int parameters
1383 were changed to size_t.
1385 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1388 New MARC decode/display function, marc_display_exl, which properly rejects
1389 non-ISO2709 records. YAZ client uses it.
1391 --- 1.8.1 2001/10/29
1393 Fix bug: local attribute set wasn't set correctly in PQF strings.
1397 * Old Z39.50 codecs no longer supported.
1399 Added ZOOM C binding. See http://zoom.z3950.org/
1401 Renamed states for COMSTACKs to avoid confusion with events.
1403 Implemented cs_look and proper cs_rcvconnect.
1405 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1407 Configure detects POSIX threads on OpenBSD.
1409 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1410 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1412 When error is returned from present handler, non-surrogate diagnostic
1413 is returned in present response (and fetch handler is no longer called).
1415 * Minor adjustments to pquery parser (PQF). Token characters may be
1416 escaped by using backslash (C-style).
1418 PQF parser allows string attribute values to be specified. For @attr,
1419 non-numeric characters after the equal-sign are treated as strings
1420 (e.g. @attr 9=title).
1422 CCL trunction character may be defined (@truncation in file)
1424 * function zget_ExtendedServicesRequest sets waitAction to
1425 waitIfPossible (was wait).
1427 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1430 CCL operator names may be set in field definition files (CCL_bibset).
1431 See ccl/bib1 for an example.
1433 Fixes in ASN.1 compiler for C++ compatibility.
1435 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1436 and "op_or" to avoid conflict with C++.
1438 Fixed problem with GNU readline detection on Redhat 7.0.
1440 Added step-size for Scan backend handler.
1442 Fixed bug that made the frontend server crash when no attribute
1443 set was specified for scan.
1445 Front-end server automatically switches to original working directory
1446 when installed as an NT service. Previously -w had to be specified to
1449 Added extended attributes for retrieval module (data1), so that data1
1450 records carry d1_readXML/SGML attributes. d1_read also supports
1451 null-data rules ( <tag/>)
1453 On UNIX when POSIX threads are available, a separate library libyazthread
1454 is created. Programmers should link with that library and the yaz library
1455 when using threads. The reason for the split was that some applications
1456 on Linux, such as Apache, doesn't work well when using shared objects that
1459 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1460 (or any frontend server) in SSL mode by specifying ssl: followed by
1461 address. Only tested on UNIX.
1463 Added feature for CCL module. Virtual structure s=al or s=ol generates
1464 and-list and or-list respectively instead of phrase search.
1468 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1469 log_mask_str. This was done to avoid name conflicts with other libraries
1470 (such as other PHP extensions).
1472 Added raw OID member for preferred record syntax (request_format_raw)
1473 and returned record syntax (output_format_raw) for backend fetch method.
1475 Config file yaz-config now accepts options so that it returns specific
1476 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1478 Shared library support for UNIX using GNU libtool.
1480 * Modified backend interface. Request/Response struct's replaced by
1481 one read/write C struct. For example bend_fetchrequest and
1482 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1483 Every handler - even search has to be registered in bend_init
1484 handler. This means that the YAZ library no longer refers to
1485 external functions and it makes it possible to make the whole
1486 thing a single DLL/SO.
1488 Added Segment handler for backend server.
1490 Added Zmbol/Zebra administrative functions to YAZ client.
1492 Threaded frontend server on UNIX (when POSIX Threads are available).
1493 Starting the server with option -T enables multi-threading.
1497 Added configure option --enable-comp/disable-comp to control use
1498 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1499 located in sub directory asn.
1501 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1502 in ${exec_prefix}/bin along with the other programs yaz-client and
1505 GNU automake used to maintain makefiles.
1507 Added several OID's.
1509 Changed retrieval module so that we can load records with no abstract
1510 syntax defined. Tagpaths in these records are fully composed of string
1513 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1517 On UNIX, the generated makefile now supports a proper 'make install'.
1518 The prefix can be set via GNU configure to set the install location
1519 (default is /usr/local).
1521 * YAZ programs client and ztest were renamed to yaz-client and
1522 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1523 locations, such as /usr/bin,/usr/local/bin,etc.
1525 * YAZ Header files were moved from include to include/yaz. YAZ Header
1526 files are referred to as include <yaz/log.h> rather than <log.h>.
1527 The YAZ include path (-I ..) is therefore the same as before. Programmers
1528 should update their #include statements or use -Ipath/include/yaz
1529 instead. The main motivation for doing this change is that YAZ header files
1530 can be installed in "standard" locations /usr/include,/usr/local/include
1531 without introducing conflicts, since ALL YAZ header files are stored
1532 in subdirectory yaz (under /usr/include for example).
1534 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1535 rather than project/workspace files. We switched because project files
1536 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1539 Changed name of logging function, logf, to yaz_log, to prevent name
1540 clash with some math-log functions. The YAZ header log.h defines logf
1541 to yaz_log (#define) so there should be no incompatibilities by this
1544 Added bend_start/bend_stop handlers for server. These handler are
1545 called on start/stop of server. For windows they are called whenever
1546 a service is started/stopped.
1548 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1549 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1550 in util/yc.tcl. The auto-generated C code structures are, in a few
1551 cases, incompatible with the old decoders. There are differences in the
1552 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1553 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1554 The preprocessor variable ASN_COMPILED is defined when the compiled
1555 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1556 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1557 wish to use the old encoders/decoders you can specify --disable-yc
1560 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1561 version so that it supports both new - and old version of DB Update
1563 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1564 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1565 change. The name parameter can be set to 0 in which no name is specified
1566 for the construction. The macros odr_implicit and odr_explicit sets name
1567 parameter to zero for the construction involved. New macros
1568 odr_implicit_tag and odr_explicit_tag are similar to the others,
1569 except that a name parameter is added. For programmers' that don't use
1570 ODR they probably only need to change the call to z_APDU and z_External.
1572 Added access control facility by interfacing the TCP wrapper library.
1573 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1574 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1575 name of the daemon and enables the access control as specified in
1576 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1578 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1579 den Dool <H.M.vdnDool@kub.nl>.
1581 Added reference ID parameter to most functions in server API - refer
1582 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1584 Changed name of ccl library to libccl.a (was ccl.a).
1586 Fixed bug in decoder for Explain (Category TargetInfo).
1588 Added support for GNU readline in client. Thanks to Jacob Poulsen
1589 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1591 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1592 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1593 IMPLEMENTATION! This change was made to the development version before
1594 the ZIG decided to retract the amendment. If any users MUST be
1595 compatible with the original Update definition, PLEASE CONTACT US, and
1596 we will include a separate definition corresponding to the old Update
1597 ES. Note that because of the change to the ASN.1 of the
1598 TaskPackageRecordStructure we cannot define a single structure that
1599 will support both versions.
1601 * Added const modifier to buffer parameter for some ODR/BER encoding
1602 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1603 completeWAIS, odr_dumpBER.
1605 Fixed bug in client.c which caused a crash when a scanResponse didn't
1606 contain positionOfTerm.
1608 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1609 * will cause an error in a client if a non-YAZ target sends both a
1610 * list of Scan entries and non-surrogate diagnostics.
1612 Retrieval module enhancements. Tag sets may be typed in the reference
1613 to it. From the .abs-file the "tagset" directive takes a third optional
1614 integer type for the tag set referenced. From a .tag-file the "include"
1615 directive takes a third optional type as well. The old "type" directive
1616 in the tag set itself is still recognized but acts as the default type
1619 Backend interface change. Individual Scan terms returned from bend_scan
1620 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1621 in include/backend.h.
1623 Retrieval module enhancements. Multiple tag sets and attribute sets may
1624 be specified in abstract syntax specs. Revised the error/warning for
1625 logging messages reported by the retrieval module when reading the
1628 Object Identifier system (oid_..) changed. The API is backwards
1629 compatible but the oid-routines now allocates new OID's when needed.
1630 Raw OID's may be specified in oid_getvalbyname.
1632 YAZ now uses GNU configure to generate Makefile(s).
1634 * Minor changes in some of the member names of DeleteResultSetRequest and
1635 DeleteResultSetResponse. See include/proto.h.
1637 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1638 and added member 'languages' in TargetInfo (which was missing).
1640 Changed the way attribute sets are handled in the retrieval
1641 module. These are now cached, just like the abstract syntaxes
1644 Changed YAZ so that it links with compiled ASN.1.
1646 Added Explain-schema definitions and mapping routines. The following
1647 Explain categories have been implemented: AttributeDetails,
1648 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1650 Fixed minor bug in Windows version of Server Library.
1652 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1654 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1656 Added EXTERNAL: UNIverse Resource Report (non-standard).
1658 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1659 ENUMERATED and SET OF.
1661 * Added 'const' to some of the char pointer arguments for the
1662 functions, data1_read_node, data1_getelementbytagname,
1663 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1666 Fixed bug in data1_insert_taggeddata - the last_child member of
1667 parent wasn't initialised.
1669 * Changed data1_read_record and data1_read_node so that the supplied
1670 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1671 doesn't refer to any parts of the "SGML"-buffer.
1673 Fixed bug in server library (Windows version of statserv_remove).
1675 * Changed code so that it compiles as C++. The type definition
1676 of Odr_fun which is a member of Odr_arm was changed. The result is,
1677 that an explicit typecast is needed for the fun pointer when
1678 using Odr_arm - as in:
1679 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1681 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1683 Implemented the new structured date and time definition as approved
1684 by the ZIG. Added schemaId element to the specificTag in Espec-1
1685 (also approved at the last ZIG). Thanks to RVDM.
1687 Added some Object identifiers (RVDM).
1689 Changed the Update Extended Service (RVDM).
1691 Added command "refid" to client which specifies referenceId for
1692 the following requests.
1694 Implemented extended service handling for server. See ztest.c
1695 for an example as well as backend.h. New handlers are registerd
1696 in the Init handler.
1698 * Changed interface for sort in server.
1700 Added new members to statserv_options_block. It allows a server
1701 to read options from another source than just the command line. Thanks
1702 to Charles Woodfield.
1704 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1705 renamed to zboolean. Some C++ compilers complained about the name.
1707 Minor changes to gils.abs. Added index 's' (sort) on title
1708 and date/time-last-modified.
1710 --- 1.4pl2 1998/1/30
1712 Fixed bug in server library regarding inetd mode (-i). This bug
1713 was introduced by release 1.4.
1715 --- 1.4pl1 1998/1/29
1717 Added sort facility in client and backend server interface.
1719 Fixed problem with dependencies in Makefile(s).
1721 Fixed bugs for encoders/decoders of extended services and
1724 Implemented sub-tree feature for schemas. Sub-trees are
1725 referenced in *.abs-files. See explain.abs for an example
1726 of the use of this feature.
1728 Modified bib1.att; local attributes for ANY didn't include
1729 ANY itself (only affects use of the retrieval module).
1731 Fixed bug in plain SGML reader in function data1_read_node:
1732 tags with prefix "var" was incorrectly interpreted as variants.
1734 Added feature "sub-schemas" to enable references to - and definitions
1735 of - group of elements.
1737 * Removed member parent from type data1_element (in data1.h).
1739 Implemented function odr_nullval() that returns the value of
1742 * Removed member num_children from data1_node (in data1.h).
1744 Made NT service interface part of the server library. The
1745 function statserv_main uses the NT service when required and
1746 calls the statserv_start / statserv_close routines.
1748 Routine zget_SearchRequest and zget_PresentRequest fills
1749 resultSetName/Id member with "default" instead of "Default".
1751 Fixed memory leak in server. Request queue member wasn't freed.
1753 Fixed nmem_exit so that memory is freed.
1757 Revised the CCL parser utility to be thread safe.
1759 Added function, oid_ent_to_oid, to replace the function
1760 oid_getoidbyent, which is not thread safe.
1762 * Added nmem_init and nmem_exit to initialize and release
1763 NMEM resources. Function nmem_init should be called once in the
1764 initial thread before NMEM/ODR is used. statserv.c and client.c
1765 have been changed accordingly. The change was necessary to make
1766 NMEM thread safe. The NMEM memory pool is shared amongst threads
1767 in a process. Unix-based applications will still work fine without
1770 Added NT Services interface for the the Z39.50 (statserv) Server.
1771 Refer to the ztest.c source on the usage.
1773 Windows 95/NT port using MSVC5.0. Project files are included in the
1776 * Defined new 'global' handle for the retrieval (data1) system. The
1777 new handled, data1_handle, describes the state of the data1 system.
1778 This handle is passed as first argument to virtually all
1779 data1 related routines. The functions data1_create and data1_destroy
1780 creates and destroys a data1 handle respectively.
1782 Added ODR encode stream member to all backend request structures
1783 init, search, scan etc. This stream should be used to allocate all
1784 memory used for the response when thread safe operation is needed.
1786 Changed the comstack utility, cs_addstr, to be thread safe. The
1787 returned hostname string returned by the function is now part the
1790 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1791 function. The cs_straddr takes a COMSTACK handle as argument, so this
1792 function must be used after cs_create and before bind/connect.
1793 This function is thread safe.
1795 Moved test server to 'ztest' directory - generic server code still
1796 in 'server' directory.
1798 Made prefix query (pquery.c) utility thread safe.
1800 Added new function modifier YAZ_EXPORT to 'export' public DLL
1801 functions when using windows (see include/yconfig.h).
1803 Added definitions to the OID database (util/oid.c) (RVDM).
1805 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1807 Added call to ccl_rpn_delete in client program.
1809 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1810 release of RPN structure.
1812 Added support for C++, headers uses extern "C" for public definitions.
1813 With input from RVDM.
1815 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1816 Thanks to Ronald van der Meer (RVDM).
1818 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1820 Added support for private extensions to the OID database
1821 (oid_setprivateoids()). Thanks to RVDM.
1823 Added optional, physical ANY (key replication)
1825 Fixed null-reference problem in GRS-1 output filter.
1827 Proximity operator added to Prefix Query Format (PQF).
1829 In test client command "base" accepts multiple databases.
1831 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1835 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1837 Smallish bug-fixes in the new encoders/decoders (explain).
1839 Bug fixed in DeleteRequest.
1841 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1843 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1845 Added SOIF syntax (using private OID for now) to retrieval module and client.
1847 Added Update extended service.
1849 Added SearchResult-1 additional info structure.
1851 Added optional CCL (ISO8777) interpreter as separate module. Available
1854 --- 1.2 1996/6/10 (1st anniversary release)
1856 Added Summary record syntax. Lightly tested.
1858 Added OPAC record syntax. Untested.
1860 Added ResourceReport service encoders/decoders. Untested.
1862 Fixed bug in z_Unit - wrong tagging on unitSystem.
1864 Fixed bug in the DiagRecs decoder.
1866 Added options for max PDU size and session timeout to frontend-server.
1868 Added documentation of query-language parsers and other supporting utilities.
1870 [frontend-server] Added Attribute set to the bend_scanrequest API.
1872 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1873 surrogate diagnostics were generated.
1875 [retrieval] Allow multiple local values for attribute.
1877 [retrieval] Allow multiple attributes per element in .abs files. index type.
1879 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1881 --- 1.1pl2 1996/4/10
1883 Minor changes, mostly specific to Zebra's requirements (retrieval)
1887 Repaired bug in frontend server when running multiple listening
1888 endpoints in dynamic mode.
1890 z_External() now won't break if a known, ASN.1 value comes encapsulated
1891 in an octet-string. The value will pass through unmodified in an Odr_oct.
1893 Added a bit of code to the demo client to decode & display
1894 ASN.1-structured records represented in the octet-aligned branch of
1895 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1897 Added z_ext_getentbyref() to the ASN module. Doc updated.
1899 * Completed the SCAN definition in the ASN module. This may break SCAN
1900 code based on older YAZ-versions at compile-time. The fix is easy -
1903 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1904 under the SCAN definition. Remember to initialize this, server-people.
1906 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1907 that this does not extend to ODR and ASN.
1909 Comstack allows insertion of established socket (primarily for
1910 inetd-operation of servers). Doc updated.
1912 Front-end server can now start from the inetd in TCP mode. Doc
1915 --- 1.0pl4 1996/1/24
1919 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1920 the rank and record number.
1922 Adjustments to the frontend server.
1924 Fixed diagnostic BER dumper. It ignored the file argument.
1928 Various changes to retrieval module.
1930 Changed the union discriminators of the protocol files from enums to
1931 ints paired with #defines.
1933 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1936 *Changed operator in the RPN structure to 'roperator', again to avoid a
1939 Fixed problems in Explain decoders/encoders.
1941 --- 1.0pl2 1995/12/6
1943 Memory bug in log module fixed.
1945 --- 1.0pl1 1995/12/5
1947 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1949 Bug in Explain DatabaseInfo module fixed.
1951 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1955 The shift to v1.0 signals that we now consider the *core* functionality
1956 of YAZ reasonably stable (the core being more or less equivalent to
1957 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1958 tested (Explain not at all - though that will happen soonish).
1960 Minor changes to code to support Windows port.
1962 Various minor changes after we're getting to use GRS-1 & co. more.
1964 Added Espec-1 format.
1966 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1967 of the protocol and it cannot be selected when encoding (maps into 'string'
1968 when decoding). Needed to talk to some servers.
1970 Demo client can request simple element set names.
1972 Added Diagnostic Format encoders/decoders.
1974 Added simple Close handling to frontend server (no hooks for resource
1975 reporting yet), and demonstration client.
1977 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1979 --- 1.0b3 1995/08/24
1981 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1982 handled incorrectly when records were requested in the searchResponse. This
1983 will only affect you if you use the frontend-server.
1985 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1986 Test-client will ask for and print GRS1. Ztest will return dummy records
1989 Added Explain encoders/decoders to the service-level API. Untested.
1991 Added Extended Services: Item Order encoders and decoders to the Service-
1992 level API. Untested. We could use a recent copy of the pertinent bits
1993 of the ILL protocol to add those bits.
1995 Added diagnostic format 1 encoders/decoders to the service-level API.
1998 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1999 odr_cons.c, which causes a more correct output.
2001 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2002 was always set to 0 when no records were requested in the searchRequest.
2004 * Added better external-handling. This shouldn't harm old code that
2005 *encodes* externals. It can break code that looks for a
2006 'single-ASN1-type' representation, since those types that are known
2007 are now decoded immediately. Look at the SUTRS sample code in
2008 seshigh.c and client.c. Documentation updated.
2010 Handling of structured records in bend_fetchresponse. Length -1 marks
2011 structured record, type is deduced from format field.
2013 --- 1.0b2 1995/06/27
2014 Fairly quick maintenance release to add SUTRS support.
2016 Fixed handling of SUTRS records in the demonstration client.
2018 * Added format field to the bend_fetchrequest and bend_fetchresponce
2019 structures of the backend API (frontend server). When the record is
2020 returned, the value of the format field is mapped to an OID. The
2021 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2022 of the record. The special value VAL_NONE in the bend_request means
2023 that no specific format was requested by the client. Documentation
2024 updated accordingly. Test server (ztest) will return a fixed dummy
2025 SUTRS record if your client requests SUTRS.
2027 Documentation updated accordingly.
2029 You can now set external libraries and RANLIB support in the top-level
2033 First public release.
