3 Fixes for configure on BSD. Bug #900.
5 Added snprintf/vsnprintf wrappers for systems that don't have
6 limits (heavens forbid).
8 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
9 created before all previous tasks were completed and removed from the
10 task queue, the new task could be removed by a mistake.
12 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
14 Implemented pass-through CQL-to-PQF conversions. Bug #861.
16 Fixed bug #832: Problem with MARC/charset in yaz-client.
18 Fixed bug #668: save command line history for yaz-client.
20 Fixed bug #830: pkg-config support.
24 Extended ZOOM result set options with two options that may be read by
25 a client: resultSetStatus and presentStatus with values as specified for
27 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
29 Fixed bug #827: Using SSL fails on Debian etch.
31 Fixed bug #826: Weird looking chars for set of MARC records.
33 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
34 that is treated as an ItemOrder with itemRequest being an XML document
35 external. The value of "doc" is the content.
37 Extended the GFS search facility. New member of bend_search_rr
38 'estimated_hit_count' signals that hits is known to be an estmate
39 (higher or lower than real hit count). New member 'partial_resultset'
40 signals that the search was partial (hit count is lower or equal than
41 real hit count). For Z39.50, the information is stored in resultSetStatus
42 member of SearchResponse APDU. For SRU, the information is signalled
43 via SRU diagnostic 59: "Result set created with valid partial results
46 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
50 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
52 Added ZOOM_connection_peek_event.
54 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
55 the following new functions:
56 ZOOM_event_nonblock, ZOOM_connection_process,
57 ZOOM_connection_get_{socket,mask,timeout},
58 ZOOM_connection_fire_event_{timeout,socket}.
59 The existing blocking event handler, ZOOM_event, is a wrapper for the
60 + blocking ZOOM_event_sys_{poll,select}.
62 Implemented function ccl_xml_config which parses XML version of CCL
63 configuration (bug #798).
65 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
67 Added timings utility (yaz/timing.h)
71 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
74 Fixed bug #779: Rotation of apdu.log fails.
76 Fixed for character set conversions:
77 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
78 Honor G1 set in MARC-8 decoding.
82 Fixed bug #775: char conversion does not handle Alternative UTF-8
85 Implemented function yaz_marc_read_line which parses MARC line format
86 records. There is a wealth of formats out there. So far, this function
87 reads line records produced by yaz_marc_write_line.
89 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
90 more generic and easier to remember(!) options: -i format and -o format
91 which specifies input format and output format respectively - where
92 format is one of "marc", "marcxml", "line", "marcxchange".
94 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
95 does not print anything except warnings for records.
97 For yaz-marcdump, added support for MARC split into files (-s) with a given
100 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
101 spec, at http://www.loc.gov/standards/sru/record-update/
102 This has changed the binary layout of the following structs:
103 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
104 bend_update_rr . Patch by Ko van der Sloot.
106 Added GFS utility function bend_assoc_is_alive which returns 1 if
107 association is still alive (client is connected); 0 otherwise (client
108 closed connection). This allows busy servers to stop working for
111 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
112 been a separate piece of software. This version of ziffy has been modified
113 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
115 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
117 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
118 Client code may now interrogate options such as "init_opt_sort" to
119 find out whether the server claims to support various options.
121 --- 2.1.40 2006/11/27
123 Added utilities yaz_{set,get}_esn to set/get element set name from
126 Removed the build of libyazthread.la. The libyaz.so is the threaded version
127 of YAZ and has been so since YAZ 2.1.10.
129 Implemented ZOOM_record_error which returns error information for
130 record (surrogate diagnostic).
132 --- 2.1.38 2006/10/31
134 Updates for SRU Update by Ko van der Sloot:
135 1. Changed name from "operation" to "action"
136 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
137 versions in the code, marked as 'backward compatible'.
138 3. Added diagnostics for SRU Update.
140 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
142 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
144 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
146 For GFS, fixed problem with SRU diagnostic 'First record position out of
147 range' being issued for 0 hits.
149 zoomtst10 part of Windows Build.
151 --- 2.1.36 2006/10/13
153 Implemented yaz_filepath_comp which splits a path into file path
154 components (required by Zebra 2.0.3+).
156 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
157 BSD inspired license until now so this should not have any real impact on
158 anybody. See http://www.opensource.org/licenses/bsd-license.php
160 Fixed bug #687: Missing log lines.
162 Fixed bug #678: CQL to PQF translation does not preserve double-quote
165 Fixed bug #689: SRU diagnostics to be added.
167 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
168 whether a connection is idle (no more work do do).
170 --- 2.1.34 2006/10/04
172 Change type of optval from long to int for invocation of setsockopt with
173 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
175 Added support for specifying the max log file size for the Generic
176 Frontend Server. The size is given with option -r.
178 --- 2.1.32 2006/09/21
180 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
182 --- 2.1.30 2006/09/17
184 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
187 Fixed bug in Generic Frontend Server that could cause a server to stop
188 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
190 For the generic frontend server, the maximum record size is used as maximum
191 size of incoming packages (SRU + Z39.50). The value until was previously
192 only used in Z39.50 Init negotiation and, later, in a session controlled
193 sizes of records returned. This is controlled using -k option. It can be
194 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
196 --- 2.1.28 2006/09/04
198 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
201 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
203 New option for yaz-marcdump -lpos=value which allows setting a portion
204 of MARC header to a certain value.
206 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
208 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
209 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
211 --- 2.1.26 2006/08/15
213 Fixed problem with SRU mode type (soap, get, post) for yaz-client
216 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
218 --- 2.1.24 2006/08/08
220 Fixed MARC ISO2709 encoding routines to deal with character set
223 Minor changes to GFS logging. Database included in search request log
226 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
227 cached/multiple records.
229 Shared libraries are built by default on Unix+configure.
231 Changed cql2pqf transformation to use a different evaluation order. The
232 new order is: always, relation, structure, position, truncation, index
233 and relationModifier. Old order was: always, relation, relationModifier,
234 structure, index, position, truncation. Note that the the latter ones
235 override former ones for identical attributes.. The new scheme means that
236 it is possible to override any existing attribute with a relationModifier.
237 And also that it is possible to override everything for the index rule
238 (except the ones listed in relationModifier). No order is perfect but this
239 one, we believe, covers more real cases.. The "always" should have been
240 called "default", since the attributes there can be overridden with all
243 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
244 compilation phase, but also for yaz-config --cflags output. This allows
245 us to have public headers with Libxml2 stuff in them . It should also,
246 eventually, make Libxml2 checks redundant in packages using YAZ, such
249 --- 2.1.22 2006/06/15
251 Changed SRU update structure bend_update_rr so that SRU diagnostics are
252 stored in uri, message and details.. Previously diagnostics were stored
253 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
254 compatibility.. but he's probably the only one affected, so.
256 Added support for CCL, compiled on the client side, in ZOOM-C. This
257 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
258 input; the resulting query objects can be used for for searching with
259 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
261 YAZ' configure searches for OpenSSL by default.
263 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
264 SL_CTX_use_certificate_file. See
265 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
266 for more info. Thanks to Ko van der Sloot.
268 --- 2.1.20 2006/06/02
270 Bug #600: SRU GET, POST support for yaz-client. Introduced
271 command 'sru' which selects method SOAP/GET/POST.
273 Allow missingValueAction to be specified for the sortspec string -
274 function yaz_sort_spec. By default, the missing value action is null.
275 Use ! to specify "abort". Use = followed by stringvalue to specify default
278 Ensured that Present-handler (if defined) is called in GFS before any call to
279 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
280 searchRetrieve requests.
282 Documentation for YAZ is now based on the Docbook XML/XSLT using
283 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
284 is no longer depending on jade/openjade or docbook-to-man scripts.
285 PDF is no longer part of the distribution - but can optionally be
286 made using DSSSL/jadetex or FOP.
288 Added retrieval handling support in Generic Frontend Server to support
289 conversion between MARC/XML as well as XSLTtransforms. See
290 etc/yazgfs.xml for an example.
292 Added Authentication support to Generic Frontend Server in SRU
293 mode. Authentication using HTTP Basic is supported, as is the use
294 of 'x-username' and 'x-password' parameters in the request itself.
296 Added support for a new character set MARC8s identical to MARC8 except
297 that it converts combined characters to single Unicode characters in the
298 Latin-1 range (when possible).
300 --- 2.1.18 2006/04/24
302 ASN.1 compiler 0.4: generates brief Doxygen file header for
303 generated .h/.c files.
305 Utility yaz_iconv now supports conversion to MARC-8.
307 New facilities for the MARC module. The reading - and writing of
308 content are separate methods for the yaz_marc_t handle. The following
309 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
310 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
311 format). Write functions have prefix yaz_marc_write_.. The existing
312 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
313 available. Removed support for OAI-MARC and simplexml (not the
314 simplexml from PHP5).
316 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
317 to be returned for this connection.
319 --- 2.1.16 2006/03/31
321 Allow multiple languages and charsets to be specified with
322 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
323 negcharset iso-8859-1,utf-8
325 Translation of proximity nodes from CQL into PQF now works.
327 Moved to automake 1.8, 1.9.
329 Added function yaz_log_set_handler which allows a log handler to be
330 installed. This handler will be called for all log messages. Output
331 to file is also produced; but that can be disabled by passing NULL
332 fname to yaz_log_init_file.
334 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
336 For SRW (including GFS), accept application/soap+xml as content-type
339 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
340 produces NO stylesheet reference even if a default stylesheet is specified
343 --- 2.1.14 2006/03/14
345 Updated Windows package to include yazd.dll + yazd.lib for the
346 Development component.
348 If the environment variable YAZ_LOG is set, then it is used as a
349 string indicating the default level of logging to use if not
350 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
351 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
352 used as before. So, for example, to omit warnings from YAZ logging,
355 cql_transform() now map structure and other attributes before indexes,
356 so that index-specific structures and other attributes can override
357 defaults. So now a combination of mapping specifications such as:
359 index.dc.date = 1=date-modified 4=5
360 does the right thing.
362 cql_transform() now also respects the "always" mapping specification,
363 which establishes an initial set of attributes to be used for all
364 terms except where overridden by more specific attributes associated
365 with the index, relation or modifier.
367 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
368 which mode to use; one of "post", "get" or "soap" (SRW, default).
370 Fixes for yaz_iconv routines: changed trie-based character set conversions
371 to use only non-negative values for bit fields due to Sun's C compiler not
372 supporting negative values.
374 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
375 sequences where not read correctly. Fix by Rustam Usmanov.
377 Updated win/makefile to use options, settings which makes things
378 compile with VS C 2005.
380 --- 2.1.12 2006/02/01
382 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
384 In ZOOM socket code, use select instead of poll on MacOSX.
386 ZOOM-C now support client-side compilation of CQL into RPN that is
387 sent to the server, enabling CQL to be used against all Z39.50
388 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
389 ZOOM_query object, and submit it using ZOOM_connection_search().
390 The CQL-to-RPN translation uses a configuration file, the name of
391 which must be specified in the Connection's "cqlfile" option.
393 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
394 function, which takes as its start-term parameter a ZOOM_query object
395 (which may have had either CQL or RPN set into it).
398 --- 2.1.10 2005/11/29
400 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
401 GFS to support this as well. Backend handler, bend_srw_update, does the
402 update work. Code contributed by Ko van der Sloot.
404 Allow retrieval of Search Result-1 information in ZOOM by the use of
405 options that are attached to a result set. ZOOM documentation updated
408 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
409 UTF-8 conversion. Patch by Raj Patel.
411 Added option -m to GFS to control formatting of timestamps in log file.
413 Added 'exit' as synonym for 'quit' in yaz-client
415 Added support for specifying SRW resultSetId + resultSetIdleTime in a
416 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
417 for the new members. Patch by Ko van der Sloot.
419 Added support for SRU POST. It is supported for content-type
420 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
422 Do not build the separate Multi-threaded (MT) library libyazthread.la.
423 Instead make the library libyaz.la multi-threaded. Threading as a whole
424 can still be disabled by configure option --disable-threads. Previosly,
425 with older GLIBCs there were problems with MT libs under Apache. This
426 has now been fixed a long time ago.
428 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
431 CQL module modified to be case insensitive for relations/indexes/operations.
433 Fixed bug in CQL transform code: incorrect value relationModifieder
436 Added 'show all' command for yaz-client which retrieves all results
439 Added new yaz-client, xmles, which takes a (private) OID and
440 a document to be sent as an extended service request.
442 Describe new yaz-client commands wait_response and set_auto_wait.
444 Increase TCP/IP listener backlog from 3 (which I am guessing was
445 copied from the SunOS manual entry way back when) so SOMAXCONN, so
446 that the socket will queue as many incoming connections as it's able
447 to handle ongoing connections. In other words, it will never now
448 refuse a connection that it would be able to handle merely because
449 it's not got around to accepting() enough of the pending connections
450 yet. This is the behaviour anyway under Linux, where the listen()
451 argument is ignored; but not under BSD and on systems such as
452 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
453 YAZ-based servers should now be uniform across operating systems in
456 yaz-marcdump uses 64-bit file access on some systems. This is enabled
457 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
458 This allows yaz-marcdump to read large MARC batches (>2 GB).
460 Modified all YAZ source files - except the source which is auto-generated
461 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
464 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
465 corresponding to the existing *_setl() function. These allow option
466 values containing arbitrary valuues.
468 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
469 ZOOM_resultset_sort() in new applications. Its behaviour is identical
470 except that it returns an indicator of whether or not the sort
471 criterion was accepted (0 for OK, -1 for invalid).
475 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
476 MARC output rather than returning "new" buffer.
478 yaz-client warns about unknown init options.
480 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
484 Added support for SRW sort in Generic Frontend Server. Patch
485 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
486 sortKeys - or NULL if none is provided.
488 Fixed bug #307: It was impossible to specify indefinite/no timeout
489 for ZOOM_event. Special timeout value -1 now means indefinite timeout
492 Added support for multiple languages and charsets to be specified in
493 ZOOM. Each charset/language is separated by a blank. If negotiation is
494 in effect in init-response, Option
495 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
496 Code based on patch by Vasiliy Osadchuk.
498 Fixed bug #306: infinite recursion that occurred when calling
499 yaz_log_level_init as the first call (before other log level or
502 Fixed bug in scan handling in front end server: if preferred-Position-In-
503 Response was non-present, a NULL pointer referece was performed.
507 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
508 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
509 now defined for all those error codes. So instead of putting 109 in
510 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
511 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
513 Modified the yaz-marcdump utility to skip garbage bytes between MARC
516 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
518 Program yaz-client now exits and produces an error message if multiple
519 Z39.50 servers are specified on the command line (none or one allowed
522 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
527 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
529 Fixed bug #272: Preserve spacing for CCL terms.
533 Added support for virtual hosts and multiple backend servers for
534 the YAZ frontend server. The configution is XML based and
535 support specificition of CQL to RPN mappings and explain information.
536 See section "Virtual Hosts" in the YAZ manual.
538 Extended OPAC display utility. OPAC display utility renders
539 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
540 to supplement yaz_marc_decode_wrbuf.
542 Fixed a bug in MARC decoder that could caused it to crash for some
543 invalid MARC records. More diagnostics and warnings where added in
544 XML output (warnings, etc are stored in comments).
546 --- 2.0.34 2005/02/08
548 Fixes for UNIX domain sockets. Bug #261.
550 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
552 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
553 Added yaz_marc_subfield_str which defines subfield lead string which is
554 used in YAZ_MARC_LINE format. Default string is blank+$. Added
555 yaz_marc_endline_str which defines end of fields string used in
556 YAZ_MARC_LINE format. Default string is newline.
558 Experimental support for MarcXChange. This format can be produced
559 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
560 http://www.bs.dk/standards/MarcXchange.xsd
562 Added yaz-client commands scansize that sets maximum number of
563 entries to be returned by scan.
565 --- 2.0.32 2005/01/11
567 Added support for SRW scan in yaz-client and Generic Frontend Server.
569 * Added whereInList member to SRW Scan Term.
571 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
573 Fixed NMEM system to return aligned blocks on the smallest boundaries
574 that are suitably aligned for all possible types on the particular
575 architecture YAZ is being built for.
577 --- 2.0.30 2005/01/04
579 Fixed numerious warnings that was issued with newer versions of GCC.
581 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
582 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
585 Make YAZ Generic Frontend Server slightly faster.
587 Enhance (and reduce) logging for Generic Frontend Server.
589 Revert YAZ log system so that it flushes every write operation
590 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
592 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
593 instead of LOG_, due to name clash with syslog(3). LOG_ are still
594 present. New applications should define YAZ_USE_NEW_LOG=1 - this
595 will effectively disable old definitions.
597 --- 2.0.28 2004/11/09
599 Added yaz_log_time_format which specifies log format using
602 Added yaz_log_module_level which returns mask for a module. Value
603 is non-zero mask a if module is enabled; zero if disabled.
605 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
606 in include/yaz/cql.h.
608 Fixed bug #176: Dont throw diagnostics on empty SRU args.
610 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
612 Fixed bug #172: RPM builds does not enable SSL.
614 Doxyfile.in part of dist. Doxyfile generated by configure.
616 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
617 are given and the corresponding component does not exist.
619 Extend CCL documentation in YAZ reference. Describe r=r.
621 --- 2.0.26 2004/10/01
623 Fixed MARC->MARCXML conversion to properly deal with
624 fields, subfields, indicators having non-ASCII characters.
626 Fixed MARC->MARCXML conversion so that ASCII control characters
627 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
630 Added YAZ GFS support for conversion from Z39.50 surrogate
631 diagnostics to SRW surrogate diagnostics.
633 Bug fix: YAZ GFS did not return schema in explainResponse.
635 --- 2.0.25 2004/09/30
637 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
638 now converts recordSchema to elementSetName as well as schema URI.
640 Fixed bug in COMSTACK that prevented HTTP request packages from being
643 --- 2.0.24 2004/09/29
645 Added CCL facility r=r "range" which is similar to r=o "ordered" but
646 does not require white-space before and after the dash in a range, e.g.
647 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
650 Fixed a few AC_TRY_LINK configure tests that did not operate properly
651 due to new GCC removing "redundant" code.
653 Added yaz-client commands scanpos and scanstep that sets preferred
654 position and step-size for scan.
656 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
658 Added CCL utility ccl_qual_buf which parses one or more CCL
659 spec lines in a buffer.
661 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
662 of name and value - ignoring empty lines and comments.
664 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
666 Added odr_get_element_path which returns current element path for an
667 ODR handle. This utility is useful in error handling or user-defined
670 Added ODR_PRINT utility odr_set_stream which is is a more generic
671 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
672 to a write function and pointer to close function. The close function - if
673 non-NULL - will be called during odr_destroy.
675 Fixed bug in CCL parser where truncation char was not removed from
676 right side when truncation=both was in effect.
678 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
681 --- 2.0.23 2004/08/11
683 Fix buffer overrun in CQL parser when dealing with proximity (%).
685 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
686 to UTF-8/UCS conversion is now only based on codetables.xml.
688 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
690 --- 2.0.22 2004/08/06
692 Add support for more "commit changes" in ZOOM (uses Extended Services).
694 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
697 Yet another small fix for configure of SSL.
699 --- 2.0.21 2004/05/14
701 Fix SSL libs for configure when --with-openssl=DIR is given.
703 --- 2.0.20 2004/05/10
705 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
707 SSL comstack now uses yaz.pem certificate file on server side
708 by default. Certificate filename can be configured by calling
709 comstack function cs_set_ssl_certificate_file before cs_bind is used.
711 Fix bug regarding multiple calls to ZOOM_connection_connect.
713 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
715 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
716 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
718 ZOOM now allows inspection of X509 peer certificate for verification.
719 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
721 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
722 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
723 as "modular" but it simplifies things.
725 Added cs_get_peer_certificate to that returns peer X509 PEM.
727 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
728 NULL if SSL is unavailable.
730 Documentation about MARC decoding tools.
732 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
734 --- 2.0.19 2004/03/30
736 Rename CHANGELOG to NEWS to follow GNU style packing.
738 Fix bug with missing initialization of member in init_diagnostics.
739 This bug affects threaded version of GFS server.
741 --- 2.0.18 2004/03/20
743 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
746 Ensure zlib.dll is packed with Windows install.
748 --- 2.0.17 2004/03/17
750 Fix encoding of xsd:string to use text instead of CDATA.
752 Fix endless loop in CQL parser with unbalanced ".
754 Use a more compact way to store MARC-8 conversion tables.
756 --- 2.0.16 2004/03/16 Debian only
758 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
761 Update CQL parser to use new CQL 1.1 modifiers for booleans and
766 --- 2.0.15 2004/03/01
768 Another fix for decoding of XML packed records.
770 --- 2.0.14 2004/02/25
772 Fixes for Chunked encoding. White space not ignored after length spec.
774 Update NS and use default NS for SRW diagnostic elements.
776 --- 2.0.13 2004/02/23
778 Implement ZOOM_resultset_cache_reset which resets record cache.
780 Implement ZOOM_resultset_sort which sorts a result set.
782 Implement chunked HTTP transfer.
784 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
786 --- 2.0.12 2004/02/16
788 Added member 'schema' to bend_explain_rr structure so that backend
789 can specify explain record identifier. Defaults to Zeerex 2.0.
791 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
793 --- 2.0.11 2004/02/16
795 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
798 Added init command for yaz-client which sends "extra" init request.
800 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
801 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
803 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
805 Make ZOOM error code for "invalid query".
807 Fixed compilation for SSL which wasn't properly enabled for all platforms.
809 --- 2.0.10 2004/02/05
811 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
814 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
816 Added option -p <file> to make Generic Frontend Server to write PID file.
818 Added option -D to put Generic Frontend Server in background on its own.
820 Make ZOOM C recognize option "password". If unset, "pass" is used
821 (for backwards compatibility).
823 Fixed a bug in Generic Frontend Server that could make it crash if a
824 client sets characterSetNegotation bit, but didn't pass negotiation stuff
827 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
828 Must be issued before open, in order to be in effect.
830 --- 2.0.9-6 2004/01/12 Debian/Windows
832 Make the SRU server more picky WRT unknown params, etc.
834 Bug fix: ZOOM scan response didn't return displayTerm - when present.
836 New YAZ client command, options, that sets Z39.50 options.
838 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
839 options from a string of tokens (one token for each option bit).
841 Update SRW diagnostic code messages.
843 --- 2.0.9-5 2004/01/07 Debian/Windows
845 Handle user defined stylesheet for SRW/SRU.
847 --- 2.0.9-4 2004/01/06 Debian/Windows
849 Fix bug in decoding of Content-Length.
851 --- 2.0.9-3 2004/01/06 Debian/Windows
853 Fix a bug with decoding of XML packed records.
855 --- 2.0.9-2 2004/01/05 Debian only
857 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
859 Fix bug in SRW/SRU diagnostics decoding.
863 Fixed bug in Generic Frontend Server which could drop records exceeding
864 preferred message size. Reported and fixed by Irina Dijour.
866 Fixed calculation of package size for structured records in Generic
867 Frontend Server. Reported and fixed by Irina Dijour.
869 Fixed namespace for SRW/SRU diagnostics.
871 Fixed SEGV in yaz-client that occured for HTTP connection errors.
875 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
876 this version is incompatible with version 1.0 and older YAZ SRW/SRU
879 CQL changes to reflect recent changes to the specification:
880 * Documentation talks about context sets instead of index sets.
881 * Documentation talks about indexes instead of qualifiers.
882 * The CQL-to-PQF transformer's configuration file now uses
883 "index.set.name = <attributes>" instead of the old form
884 "qualifier.set.name = <attributes>". (Both forms are still
885 understood but the latter is deprecated.)
886 * CQL terms with no explicit index specified are now interpreted as
887 cql.serverChoice instead of srw.serverChoice (which of course
888 behaves exactly the same.)
892 MARC conversion can now generate ISO2709 output in another
893 character set. yaz-marcdump uses this facility if you invoke it
896 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
897 functions from there can be used from C++.
901 Frontend server now transfers memory from decoded packages to stream
904 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
905 references to show up.
907 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
908 the ZOOM Abstract API. The older names for the same options are still
909 also supported for the benefit of old applications.
911 ZOOM-C supports "implementationId" and "implementationVersion" options
912 to go along with "implementationName". These allow the user code to
913 specify identification strings to be sent to servers.
914 Add OID for the new ExtLite attribute set.
916 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
917 as requested/supplid by Ere Maijala <ere@atp.fi>
919 For generic frontend server, reverse the order of
920 "toolkit-supplied / application-supplied" strings sent as implementationId,
921 Name and Version. Also, remove the spaces around the slash. This brings
922 the GFS in line with the behaviour of ZOOM-C on the client side.
924 Add function ZOOM_scanset_display_term.
926 yaz-client shows scan displayTerm if present.
928 Utility yaz-iconv is now installed by default along with the man page
931 Extend configure check for OpenSSL to use pkg-config where available (such
934 Incorporate patch by Morten Bogeskov which allows a Unix file socket
935 server to specify uid/gid/mask for socket using the format
936 unix:[user=uid,][group=gid,][umask=mask,]file=path
937 If file= is omitted the existing format is assumed, e.g.
939 in which case the mask is 0666 (rw for everybody).
941 Major restructure of YAZ source. All source in libyaz is in src directory.
942 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
943 util (utility programs such as ASN.1 compiler, yaz-marcdump).
945 Added man page for utility yaz-marcdump (used to be called marcdump).
946 yaz-marcdump is installed by 'make install'.
948 Fixed a memory leak in Generic Frontend Server that occurred when decoding
949 of incoming package failed.
951 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
953 Change prototype of odr_perror: add const to message string.
955 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
957 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
958 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
959 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
960 DNS lookup. There should not be any compatibility problems with this
961 assuming that blocking=1 or 0 is used.
963 Fix bad reference in UNIX comstack in function cs_addrstr.
965 Fix for compilation on AIX.
967 The generic front-end server (server/seshigh.c) now supports returning
968 Init diagnostics to the client in User-information-field, in
969 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
974 Allow any CQL relation (not just all,any,exact,scr).
976 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
977 that features the same UI.
979 Implemented command update0 in YAZ client which is equivalent to
980 update but uses old of Ext Update ASN.1.
982 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
983 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
984 Previously no OID was used for this info.
986 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
987 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
988 returns 'malformed search term' otherwise.
990 SortResponse member resultCount now set to NULL in sort handler of
993 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
996 Add three new utility functions for translating OIDs between various
997 formats -- symbolic name such as "Usmarc", minus-1-terminated int
998 arrays and dotted strings such as "1.2.840.10003.9.5.1":
999 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1000 char *oid_to_dotstring(const int *oid, char *oidbuf);
1001 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1003 Reverted modifications for ES Update definition for z_IU0Update
1004 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1005 is back to YAZ 2.0.2.
1007 String value attributes for CCL parser.
1009 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1010 which their FirstSearch server returns in Init responses, sometimes
1011 carrying useful diagnostic information when Init fails. This has the
1012 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1013 "z39.50/oclcui.asn", where its definition is somewhat different from
1014 what OCLC document on their web-site, as required to interoperate with
1017 Support for anonymous authentication in yaz-client. Use the command
1020 * Fix the OID of the Index Data-local "admin" Extended Service from
1021 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1022 the 1000, which indicates a locally-defined OID, was a mistake.
1024 --- 2.0.3 2003/06/20
1026 Fix CCL directive @case handling so that it affects string match for
1027 both CCL keywords and qualifiers.
1029 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1030 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1031 Decoder has been updated with ASN.1 changes as listed in
1032 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1033 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1034 z_IUUpdate, remains unchanged.
1036 ZOOM_record_get may now return a record in a specific character set.
1037 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1038 "from" is the character set of record as returned by target. "to" is
1039 the character set to be returned. If omitted, "to" is UTF-8.
1041 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1043 New ODR utility, odr_getelement, which returns name of element for
1044 which encoding/decoding failed.
1046 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1047 in cases where a required element was omitted.
1049 Bug fix: some MARC8 sequences were not converted.
1051 New ZOOM option "step" which specifies number of records to be
1052 retrieved in one chunk. Used in conjunction with "start" and "count".
1054 SRW support for yaz-client. Use scheme http: to use it, e.g.
1057 yaz-client no longer does (un)intelligent character set conversions
1058 by default. Can be enabled with charset and marc_charset commands.
1060 xmalloc trace fix for 64-bit systems such as DEC alpha.
1062 Solaris 2.6 compile fix.
1064 New function, cql_strerror() translates SRW error codes, as returned
1065 by cql_transform_error(), into human-readable English strings. Used
1066 in yaz-client diagnostics when appropriate.
1068 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1069 converts it into a type-1 query which is sent to the server. This
1070 makes CQL available for use with all Z-servers, as opposed to the tiny
1071 minority that can handle CQL queries themselves.
1073 --- 2.0.2 2003/04/28
1075 New Debian package layout similar to the Redhat Package layout.
1077 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1078 and search result respectively.
1080 --- 2.0.1 2003/04/25
1082 Redhat package is now several packages: libyaz (runtime libraries),
1083 libyaz-devel (development and documentation, and yaz (utility programs).
1084 Package spec file by Morten Bøgeskov.
1086 New member 'schema' in struct bend_fetch_rr which the name of requested
1087 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1088 handler MAY set this to reflect the schema of the returned record.
1090 New member 'display_term' in struct scan_entry. GFS now sets member entries
1091 and allocates scan entries to be filled by user scan handler. In previous
1092 version, entries member was allocated by the scan handler. That still works,
1093 but the GFS will ignore member display_term - assuming it was NOT set by
1094 the handler. The fact that the GFS now allocates the entries both allows
1095 for new members and makes a scan handler easier to write.
1097 Fix CQL lex buffer overflow.
1099 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1100 SRU default recordPacking is string.
1102 SRU protocol support for frontend server.
1104 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1106 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1108 Added scan for the ZOOM shell (zoomsh).
1112 * String Identifers for Schemas (Amendment 5).
1113 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1114 Old definition for schema
1115 Odr_oid *schema; /* OPT */
1120 Z_InternationalString *uri;
1121 #define Z_Schema_oid 1
1122 #define Z_Schema_uri 2
1125 * resultCount parameter to Sort Response (Amendment 1).
1126 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1128 Support for SRW 1.0 over HTTP. This is an optional feature and
1129 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1132 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1133 on the same port. SRW SearchRetrieveRequests are mapped
1134 to bend_init,bend_search,bend_fetch,bend_close.
1136 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1138 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1139 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1141 ZOOM connections are SRW based if schem http is used for hostname
1142 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1143 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1145 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1146 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1147 distance=n, order=true/false, relation=le, prox unit=word. If
1148 n is omitted, distance 1 is used.
1150 Fixed problem with C compiler include path in wrong order.
1152 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1153 on Solaris. Patch from Ko van der Sloot.
1155 New MARC decode API. All new functions operate on a yaz_marc_t
1156 handle. The most important new functions are: yaz_marc_create,
1157 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1158 decode and destroy respectively. Decoder can produce formats
1159 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1160 include/yaz/marcdisp.h.
1162 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1163 to UTF-8, UCS-32, wchar_t or Latin-1.
1165 * Prototypes for yaz_iconv_-functions moved to separate header
1166 include/yaz/yaz-iconv.h.
1168 Make a few private functions 'static' in unix.c. This prevents
1169 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1171 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1172 are set when Init Response is received.
1174 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1175 but returns diagnostic set as well.
1177 New function yaz_strerror which is a portable wrapper for
1178 strerror/strerror_r/GetLastMessage.
1180 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1181 is returned for MARC. If type is "oai", then OAI MARC is returned.
1183 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1186 --- 1.9.2 2002/11/26
1188 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1190 Fix bad race conditions on SIGTERM and terminate gracefully in
1193 Move retrieval (data1) module to Zebra since nobody seems to be
1196 Add GRS-1 render for ZOOM using same format as yaz-client.
1198 --- 1.9.1 2002/10/05
1200 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1202 Fix broken ESpec handling in data1 module.
1204 SGML reader parses comments and makes them part of the data1 tree.
1206 Added several type casts so that YAZ compiles as C++ code.
1208 ZOOM didn't handle PDU encoding failures properly.
1210 Added more Bib-1 diagnostics (approved extensions).
1212 GNU configure: better check for iconv.
1214 More portable use of accept, getpeername. Check for socklen_t. Use
1215 int/size_t if socklen_t is not defined.
1219 PQF parser rejects bad queries - including those with extra
1220 characters in them. PQF parser used to silently ignore that.
1221 Cleaner API for PQF added, which allows you to get detailed
1222 error information for bad queries (see yaz/pquery.h).
1224 Fixed bug in ZOOM_record_get for type "database".
1226 Implemented mini iconv library supporting conversions between
1227 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1229 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1231 --- 1.8.9 2002/08/20
1233 Fixed ZOOM C record cache so that preferredRecordSyntax and
1234 elementSetName is used to check for already fetched records.
1236 --- 1.8.8 2002/08/02
1238 Added three members in bend_initrequest structure to facilitate
1239 character set negotiation.
1241 Fixed a bug in frontend server that could cause indefinite
1242 loops under rare conditions.
1244 Revised character set utilities (charneg.h) so that encoding
1245 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1247 For PQF, directive @term <type> sets term type for Scan/Search.
1248 Here <type> is general, string, numeric, null. The term type
1249 is inherited - just like @attr.
1251 New call odr_set_charset that sets character set conversion for
1252 international-strings on a ODR stream. Prototype is:
1253 int odr_set_charset(ODR o, const char *to, const char *from);
1254 The InternationalString is still represented as C string in YAZ
1255 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1256 won't). On the protocol level, you can use any encoding.
1258 Support for UNIX sockets in ZOOM.
1260 Solaris recv sometimes returns errno == ENOENT. It is treated as
1261 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1263 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1264 both client and server. Code by Morten Bøgeskov.
1266 --- 1.8.7 2002/05/22
1268 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1269 that they can be used directly from Visual Basic. You must recompile
1270 your windows APP if you're using ZOOM.
1272 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1273 Commands "lang" and "charset" sets language and character set respectively.
1274 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1275 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1277 Attributes from multiple CCL fields may be OR'ed rather than merged
1278 using directive "@field or". Fields are still merged by default -
1279 equivalent to "@field merge".
1281 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1284 Fixed bug in zget for parameter ExtendedServicesResponse.
1288 --- 1.8.6 2002/03/25
1290 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1292 Client displays USR.1:SearchResult-1 (hits per term).
1294 Additional Search Info for search in Generic Frontend Server.
1296 Fixed CCL parsing of "field=s".
1298 WIN32 installer - using the excellent NSIS software from nullsoft.
1300 Fixed CCL parsing of "field = - <number>".
1302 Added function yaz_marc_decode that decodes MARC for line mode
1303 display or XML (similar to that used by JZKit).
1305 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1306 Z39.50. But ISO/ILL was, however.
1308 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1309 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1314 --- 1.8.5 2002/02/03
1316 New YAZ client features: Command completion and new commands:
1317 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1318 Code provided by Jacob Poulsen.
1320 New call oid_trav, that visits all registered OIDs via callback.
1322 Function ZOOM_record_get now returns const char pointer rather than
1323 void pointer. It saves a lot of type casts.
1325 For YAZ client, command "auth" now allows you to set authentication
1326 in IdPass style. It is enabled when three tokens are given - order
1327 is user, group and password.
1329 Fix memory leaks in MARC record handling for ZOOM.
1331 New option for YAZ client, -k <kilobytes> that sets
1332 maximum record size. Similar to -k option for generic frontend
1333 server and yaz-ztest.
1335 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1337 Prefix query parser reports "fail" when bad attribute set is given.
1339 Fix in MARC decoder. Proximity logging. Fix for attribute set
1340 in scan handler for server. Patches by Shigeru Ishida.
1342 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1345 Configure option --with-openssl=<dir> now works when a directory is
1346 specified. Patch provided by Morten Bøgeskov.
1348 New option for YAZ client, -u <auth>, that sets authentication.
1350 ZOOM fix: error information was sometimes "missing", since error
1351 was cleared/reset too when it shouldn't.
1353 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1355 --- 1.8.4 2002/01/04
1357 Scan for ZOOM API. New object ZOOM_scanset. New functions
1358 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1359 ZOOM_scanset_destroy.
1361 New ZOOM function, ZOOM_connection_last_event, that returns type
1362 of last event (such as "receive data", "send data", "apdu received",
1365 New ZOOM option, schema, that specifies schema for retrieval.
1367 New CCL feature. Qualifiers can be aliases for one or more
1368 other qualifiers (if more than one is given, OR is used).
1370 ZOOM uses named result sets if target supports it.
1372 Two new YAZ client commands: . (dot, which sources a script of YAZ
1373 client commands), and ! (to execute shell command.). Implemented
1376 Working on Debian packages.
1378 --- 1.8.3 2001/11/19
1380 YAZ client enables named result sets only if target supports it.
1382 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1384 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1385 with key="host" to get same result.
1387 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1388 Function Z3950_resultset_record(s) returns references to records
1389 "owned" by resultset. To become owner use Z3950_record_clone.
1391 Function z_ext_record handles Extended Services. Thanks to
1394 --- 1.8.2 2001/11/12
1396 CCL Parser fix: ignore token comma when dealing with and-lists.
1398 Documentation updates for COMSTACK.
1400 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1401 Changed prototype Z3950_records. For some functions, int parameters
1402 were changed to size_t.
1404 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1407 New MARC decode/display function, marc_display_exl, which properly rejects
1408 non-ISO2709 records. YAZ client uses it.
1410 --- 1.8.1 2001/10/29
1412 Fix bug: local attribute set wasn't set correctly in PQF strings.
1416 * Old Z39.50 codecs no longer supported.
1418 Added ZOOM C binding. See http://zoom.z3950.org/
1420 Renamed states for COMSTACKs to avoid confusion with events.
1422 Implemented cs_look and proper cs_rcvconnect.
1424 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1426 Configure detects POSIX threads on OpenBSD.
1428 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1429 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1431 When error is returned from present handler, non-surrogate diagnostic
1432 is returned in present response (and fetch handler is no longer called).
1434 * Minor adjustments to pquery parser (PQF). Token characters may be
1435 escaped by using backslash (C-style).
1437 PQF parser allows string attribute values to be specified. For @attr,
1438 non-numeric characters after the equal-sign are treated as strings
1439 (e.g. @attr 9=title).
1441 CCL trunction character may be defined (@truncation in file)
1443 * function zget_ExtendedServicesRequest sets waitAction to
1444 waitIfPossible (was wait).
1446 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1449 CCL operator names may be set in field definition files (CCL_bibset).
1450 See ccl/bib1 for an example.
1452 Fixes in ASN.1 compiler for C++ compatibility.
1454 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1455 and "op_or" to avoid conflict with C++.
1457 Fixed problem with GNU readline detection on Redhat 7.0.
1459 Added step-size for Scan backend handler.
1461 Fixed bug that made the frontend server crash when no attribute
1462 set was specified for scan.
1464 Front-end server automatically switches to original working directory
1465 when installed as an NT service. Previously -w had to be specified to
1468 Added extended attributes for retrieval module (data1), so that data1
1469 records carry d1_readXML/SGML attributes. d1_read also supports
1470 null-data rules ( <tag/>)
1472 On UNIX when POSIX threads are available, a separate library libyazthread
1473 is created. Programmers should link with that library and the yaz library
1474 when using threads. The reason for the split was that some applications
1475 on Linux, such as Apache, doesn't work well when using shared objects that
1478 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1479 (or any frontend server) in SSL mode by specifying ssl: followed by
1480 address. Only tested on UNIX.
1482 Added feature for CCL module. Virtual structure s=al or s=ol generates
1483 and-list and or-list respectively instead of phrase search.
1487 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1488 log_mask_str. This was done to avoid name conflicts with other libraries
1489 (such as other PHP extensions).
1491 Added raw OID member for preferred record syntax (request_format_raw)
1492 and returned record syntax (output_format_raw) for backend fetch method.
1494 Config file yaz-config now accepts options so that it returns specific
1495 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1497 Shared library support for UNIX using GNU libtool.
1499 * Modified backend interface. Request/Response struct's replaced by
1500 one read/write C struct. For example bend_fetchrequest and
1501 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1502 Every handler - even search has to be registered in bend_init
1503 handler. This means that the YAZ library no longer refers to
1504 external functions and it makes it possible to make the whole
1505 thing a single DLL/SO.
1507 Added Segment handler for backend server.
1509 Added Zmbol/Zebra administrative functions to YAZ client.
1511 Threaded frontend server on UNIX (when POSIX Threads are available).
1512 Starting the server with option -T enables multi-threading.
1516 Added configure option --enable-comp/disable-comp to control use
1517 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1518 located in sub directory asn.
1520 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1521 in ${exec_prefix}/bin along with the other programs yaz-client and
1524 GNU automake used to maintain makefiles.
1526 Added several OID's.
1528 Changed retrieval module so that we can load records with no abstract
1529 syntax defined. Tagpaths in these records are fully composed of string
1532 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1536 On UNIX, the generated makefile now supports a proper 'make install'.
1537 The prefix can be set via GNU configure to set the install location
1538 (default is /usr/local).
1540 * YAZ programs client and ztest were renamed to yaz-client and
1541 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1542 locations, such as /usr/bin,/usr/local/bin,etc.
1544 * YAZ Header files were moved from include to include/yaz. YAZ Header
1545 files are referred to as include <yaz/log.h> rather than <log.h>.
1546 The YAZ include path (-I ..) is therefore the same as before. Programmers
1547 should update their #include statements or use -Ipath/include/yaz
1548 instead. The main motivation for doing this change is that YAZ header files
1549 can be installed in "standard" locations /usr/include,/usr/local/include
1550 without introducing conflicts, since ALL YAZ header files are stored
1551 in subdirectory yaz (under /usr/include for example).
1553 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1554 rather than project/workspace files. We switched because project files
1555 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1558 Changed name of logging function, logf, to yaz_log, to prevent name
1559 clash with some math-log functions. The YAZ header log.h defines logf
1560 to yaz_log (#define) so there should be no incompatibilities by this
1563 Added bend_start/bend_stop handlers for server. These handler are
1564 called on start/stop of server. For windows they are called whenever
1565 a service is started/stopped.
1567 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1568 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1569 in util/yc.tcl. The auto-generated C code structures are, in a few
1570 cases, incompatible with the old decoders. There are differences in the
1571 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1572 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1573 The preprocessor variable ASN_COMPILED is defined when the compiled
1574 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1575 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1576 wish to use the old encoders/decoders you can specify --disable-yc
1579 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1580 version so that it supports both new - and old version of DB Update
1582 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1583 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1584 change. The name parameter can be set to 0 in which no name is specified
1585 for the construction. The macros odr_implicit and odr_explicit sets name
1586 parameter to zero for the construction involved. New macros
1587 odr_implicit_tag and odr_explicit_tag are similar to the others,
1588 except that a name parameter is added. For programmers' that don't use
1589 ODR they probably only need to change the call to z_APDU and z_External.
1591 Added access control facility by interfacing the TCP wrapper library.
1592 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1593 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1594 name of the daemon and enables the access control as specified in
1595 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1597 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1598 den Dool <H.M.vdnDool@kub.nl>.
1600 Added reference ID parameter to most functions in server API - refer
1601 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1603 Changed name of ccl library to libccl.a (was ccl.a).
1605 Fixed bug in decoder for Explain (Category TargetInfo).
1607 Added support for GNU readline in client. Thanks to Jacob Poulsen
1608 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1610 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1611 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1612 IMPLEMENTATION! This change was made to the development version before
1613 the ZIG decided to retract the amendment. If any users MUST be
1614 compatible with the original Update definition, PLEASE CONTACT US, and
1615 we will include a separate definition corresponding to the old Update
1616 ES. Note that because of the change to the ASN.1 of the
1617 TaskPackageRecordStructure we cannot define a single structure that
1618 will support both versions.
1620 * Added const modifier to buffer parameter for some ODR/BER encoding
1621 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1622 completeWAIS, odr_dumpBER.
1624 Fixed bug in client.c which caused a crash when a scanResponse didn't
1625 contain positionOfTerm.
1627 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1628 * will cause an error in a client if a non-YAZ target sends both a
1629 * list of Scan entries and non-surrogate diagnostics.
1631 Retrieval module enhancements. Tag sets may be typed in the reference
1632 to it. From the .abs-file the "tagset" directive takes a third optional
1633 integer type for the tag set referenced. From a .tag-file the "include"
1634 directive takes a third optional type as well. The old "type" directive
1635 in the tag set itself is still recognized but acts as the default type
1638 Backend interface change. Individual Scan terms returned from bend_scan
1639 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1640 in include/backend.h.
1642 Retrieval module enhancements. Multiple tag sets and attribute sets may
1643 be specified in abstract syntax specs. Revised the error/warning for
1644 logging messages reported by the retrieval module when reading the
1647 Object Identifier system (oid_..) changed. The API is backwards
1648 compatible but the oid-routines now allocates new OID's when needed.
1649 Raw OID's may be specified in oid_getvalbyname.
1651 YAZ now uses GNU configure to generate Makefile(s).
1653 * Minor changes in some of the member names of DeleteResultSetRequest and
1654 DeleteResultSetResponse. See include/proto.h.
1656 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1657 and added member 'languages' in TargetInfo (which was missing).
1659 Changed the way attribute sets are handled in the retrieval
1660 module. These are now cached, just like the abstract syntaxes
1663 Changed YAZ so that it links with compiled ASN.1.
1665 Added Explain-schema definitions and mapping routines. The following
1666 Explain categories have been implemented: AttributeDetails,
1667 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1669 Fixed minor bug in Windows version of Server Library.
1671 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1673 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1675 Added EXTERNAL: UNIverse Resource Report (non-standard).
1677 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1678 ENUMERATED and SET OF.
1680 * Added 'const' to some of the char pointer arguments for the
1681 functions, data1_read_node, data1_getelementbytagname,
1682 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1685 Fixed bug in data1_insert_taggeddata - the last_child member of
1686 parent wasn't initialised.
1688 * Changed data1_read_record and data1_read_node so that the supplied
1689 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1690 doesn't refer to any parts of the "SGML"-buffer.
1692 Fixed bug in server library (Windows version of statserv_remove).
1694 * Changed code so that it compiles as C++. The type definition
1695 of Odr_fun which is a member of Odr_arm was changed. The result is,
1696 that an explicit typecast is needed for the fun pointer when
1697 using Odr_arm - as in:
1698 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1700 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1702 Implemented the new structured date and time definition as approved
1703 by the ZIG. Added schemaId element to the specificTag in Espec-1
1704 (also approved at the last ZIG). Thanks to RVDM.
1706 Added some Object identifiers (RVDM).
1708 Changed the Update Extended Service (RVDM).
1710 Added command "refid" to client which specifies referenceId for
1711 the following requests.
1713 Implemented extended service handling for server. See ztest.c
1714 for an example as well as backend.h. New handlers are registerd
1715 in the Init handler.
1717 * Changed interface for sort in server.
1719 Added new members to statserv_options_block. It allows a server
1720 to read options from another source than just the command line. Thanks
1721 to Charles Woodfield.
1723 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1724 renamed to zboolean. Some C++ compilers complained about the name.
1726 Minor changes to gils.abs. Added index 's' (sort) on title
1727 and date/time-last-modified.
1729 --- 1.4pl2 1998/1/30
1731 Fixed bug in server library regarding inetd mode (-i). This bug
1732 was introduced by release 1.4.
1734 --- 1.4pl1 1998/1/29
1736 Added sort facility in client and backend server interface.
1738 Fixed problem with dependencies in Makefile(s).
1740 Fixed bugs for encoders/decoders of extended services and
1743 Implemented sub-tree feature for schemas. Sub-trees are
1744 referenced in *.abs-files. See explain.abs for an example
1745 of the use of this feature.
1747 Modified bib1.att; local attributes for ANY didn't include
1748 ANY itself (only affects use of the retrieval module).
1750 Fixed bug in plain SGML reader in function data1_read_node:
1751 tags with prefix "var" was incorrectly interpreted as variants.
1753 Added feature "sub-schemas" to enable references to - and definitions
1754 of - group of elements.
1756 * Removed member parent from type data1_element (in data1.h).
1758 Implemented function odr_nullval() that returns the value of
1761 * Removed member num_children from data1_node (in data1.h).
1763 Made NT service interface part of the server library. The
1764 function statserv_main uses the NT service when required and
1765 calls the statserv_start / statserv_close routines.
1767 Routine zget_SearchRequest and zget_PresentRequest fills
1768 resultSetName/Id member with "default" instead of "Default".
1770 Fixed memory leak in server. Request queue member wasn't freed.
1772 Fixed nmem_exit so that memory is freed.
1776 Revised the CCL parser utility to be thread safe.
1778 Added function, oid_ent_to_oid, to replace the function
1779 oid_getoidbyent, which is not thread safe.
1781 * Added nmem_init and nmem_exit to initialize and release
1782 NMEM resources. Function nmem_init should be called once in the
1783 initial thread before NMEM/ODR is used. statserv.c and client.c
1784 have been changed accordingly. The change was necessary to make
1785 NMEM thread safe. The NMEM memory pool is shared amongst threads
1786 in a process. Unix-based applications will still work fine without
1789 Added NT Services interface for the the Z39.50 (statserv) Server.
1790 Refer to the ztest.c source on the usage.
1792 Windows 95/NT port using MSVC5.0. Project files are included in the
1795 * Defined new 'global' handle for the retrieval (data1) system. The
1796 new handled, data1_handle, describes the state of the data1 system.
1797 This handle is passed as first argument to virtually all
1798 data1 related routines. The functions data1_create and data1_destroy
1799 creates and destroys a data1 handle respectively.
1801 Added ODR encode stream member to all backend request structures
1802 init, search, scan etc. This stream should be used to allocate all
1803 memory used for the response when thread safe operation is needed.
1805 Changed the comstack utility, cs_addstr, to be thread safe. The
1806 returned hostname string returned by the function is now part the
1809 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1810 function. The cs_straddr takes a COMSTACK handle as argument, so this
1811 function must be used after cs_create and before bind/connect.
1812 This function is thread safe.
1814 Moved test server to 'ztest' directory - generic server code still
1815 in 'server' directory.
1817 Made prefix query (pquery.c) utility thread safe.
1819 Added new function modifier YAZ_EXPORT to 'export' public DLL
1820 functions when using windows (see include/yconfig.h).
1822 Added definitions to the OID database (util/oid.c) (RVDM).
1824 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1826 Added call to ccl_rpn_delete in client program.
1828 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1829 release of RPN structure.
1831 Added support for C++, headers uses extern "C" for public definitions.
1832 With input from RVDM.
1834 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1835 Thanks to Ronald van der Meer (RVDM).
1837 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1839 Added support for private extensions to the OID database
1840 (oid_setprivateoids()). Thanks to RVDM.
1842 Added optional, physical ANY (key replication)
1844 Fixed null-reference problem in GRS-1 output filter.
1846 Proximity operator added to Prefix Query Format (PQF).
1848 In test client command "base" accepts multiple databases.
1850 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1854 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1856 Smallish bug-fixes in the new encoders/decoders (explain).
1858 Bug fixed in DeleteRequest.
1860 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1862 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1864 Added SOIF syntax (using private OID for now) to retrieval module and client.
1866 Added Update extended service.
1868 Added SearchResult-1 additional info structure.
1870 Added optional CCL (ISO8777) interpreter as separate module. Available
1873 --- 1.2 1996/6/10 (1st anniversary release)
1875 Added Summary record syntax. Lightly tested.
1877 Added OPAC record syntax. Untested.
1879 Added ResourceReport service encoders/decoders. Untested.
1881 Fixed bug in z_Unit - wrong tagging on unitSystem.
1883 Fixed bug in the DiagRecs decoder.
1885 Added options for max PDU size and session timeout to frontend-server.
1887 Added documentation of query-language parsers and other supporting utilities.
1889 [frontend-server] Added Attribute set to the bend_scanrequest API.
1891 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1892 surrogate diagnostics were generated.
1894 [retrieval] Allow multiple local values for attribute.
1896 [retrieval] Allow multiple attributes per element in .abs files. index type.
1898 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1900 --- 1.1pl2 1996/4/10
1902 Minor changes, mostly specific to Zebra's requirements (retrieval)
1906 Repaired bug in frontend server when running multiple listening
1907 endpoints in dynamic mode.
1909 z_External() now won't break if a known, ASN.1 value comes encapsulated
1910 in an octet-string. The value will pass through unmodified in an Odr_oct.
1912 Added a bit of code to the demo client to decode & display
1913 ASN.1-structured records represented in the octet-aligned branch of
1914 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1916 Added z_ext_getentbyref() to the ASN module. Doc updated.
1918 * Completed the SCAN definition in the ASN module. This may break SCAN
1919 code based on older YAZ-versions at compile-time. The fix is easy -
1922 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1923 under the SCAN definition. Remember to initialize this, server-people.
1925 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1926 that this does not extend to ODR and ASN.
1928 Comstack allows insertion of established socket (primarily for
1929 inetd-operation of servers). Doc updated.
1931 Front-end server can now start from the inetd in TCP mode. Doc
1934 --- 1.0pl4 1996/1/24
1938 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1939 the rank and record number.
1941 Adjustments to the frontend server.
1943 Fixed diagnostic BER dumper. It ignored the file argument.
1947 Various changes to retrieval module.
1949 Changed the union discriminators of the protocol files from enums to
1950 ints paired with #defines.
1952 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1955 *Changed operator in the RPN structure to 'roperator', again to avoid a
1958 Fixed problems in Explain decoders/encoders.
1960 --- 1.0pl2 1995/12/6
1962 Memory bug in log module fixed.
1964 --- 1.0pl1 1995/12/5
1966 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1968 Bug in Explain DatabaseInfo module fixed.
1970 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1974 The shift to v1.0 signals that we now consider the *core* functionality
1975 of YAZ reasonably stable (the core being more or less equivalent to
1976 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1977 tested (Explain not at all - though that will happen soonish).
1979 Minor changes to code to support Windows port.
1981 Various minor changes after we're getting to use GRS-1 & co. more.
1983 Added Espec-1 format.
1985 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1986 of the protocol and it cannot be selected when encoding (maps into 'string'
1987 when decoding). Needed to talk to some servers.
1989 Demo client can request simple element set names.
1991 Added Diagnostic Format encoders/decoders.
1993 Added simple Close handling to frontend server (no hooks for resource
1994 reporting yet), and demonstration client.
1996 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1998 --- 1.0b3 1995/08/24
2000 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2001 handled incorrectly when records were requested in the searchResponse. This
2002 will only affect you if you use the frontend-server.
2004 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2005 Test-client will ask for and print GRS1. Ztest will return dummy records
2008 Added Explain encoders/decoders to the service-level API. Untested.
2010 Added Extended Services: Item Order encoders and decoders to the Service-
2011 level API. Untested. We could use a recent copy of the pertinent bits
2012 of the ILL protocol to add those bits.
2014 Added diagnostic format 1 encoders/decoders to the service-level API.
2017 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2018 odr_cons.c, which causes a more correct output.
2020 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2021 was always set to 0 when no records were requested in the searchRequest.
2023 * Added better external-handling. This shouldn't harm old code that
2024 *encodes* externals. It can break code that looks for a
2025 'single-ASN1-type' representation, since those types that are known
2026 are now decoded immediately. Look at the SUTRS sample code in
2027 seshigh.c and client.c. Documentation updated.
2029 Handling of structured records in bend_fetchresponse. Length -1 marks
2030 structured record, type is deduced from format field.
2032 --- 1.0b2 1995/06/27
2033 Fairly quick maintenance release to add SUTRS support.
2035 Fixed handling of SUTRS records in the demonstration client.
2037 * Added format field to the bend_fetchrequest and bend_fetchresponce
2038 structures of the backend API (frontend server). When the record is
2039 returned, the value of the format field is mapped to an OID. The
2040 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2041 of the record. The special value VAL_NONE in the bend_request means
2042 that no specific format was requested by the client. Documentation
2043 updated accordingly. Test server (ztest) will return a fixed dummy
2044 SUTRS record if your client requests SUTRS.
2046 Documentation updated accordingly.
2048 You can now set external libraries and RANLIB support in the top-level
2052 First public release.
