3 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
4 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
5 fd_set structure used as a bitmask for the FDs to be selected on.
7 Using ACX_PTHREAD macro to check for POSIX threads.
9 Fixed have-vsnprintf check.
13 Fixes for configure on BSD. Bug #900.
15 Added snprintf/vsnprintf wrappers for systems that don't have
16 limits (heavens forbid).
18 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
19 created before all previous tasks were completed and removed from the
20 task queue, the new task could be removed by a mistake.
22 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
24 Implemented pass-through CQL-to-PQF conversions. Bug #861.
26 Fixed bug #832: Problem with MARC/charset in yaz-client.
28 Fixed bug #668: save command line history for yaz-client.
30 Fixed bug #830: pkg-config support.
34 Extended ZOOM result set options with two options that may be read by
35 a client: resultSetStatus and presentStatus with values as specified for
37 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
39 Fixed bug #827: Using SSL fails on Debian etch.
41 Fixed bug #826: Weird looking chars for set of MARC records.
43 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
44 that is treated as an ItemOrder with itemRequest being an XML document
45 external. The value of "doc" is the content.
47 Extended the GFS search facility. New member of bend_search_rr
48 'estimated_hit_count' signals that hits is known to be an estmate
49 (higher or lower than real hit count). New member 'partial_resultset'
50 signals that the search was partial (hit count is lower or equal than
51 real hit count). For Z39.50, the information is stored in resultSetStatus
52 member of SearchResponse APDU. For SRU, the information is signalled
53 via SRU diagnostic 59: "Result set created with valid partial results
56 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
60 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
62 Added ZOOM_connection_peek_event.
64 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
65 the following new functions:
66 ZOOM_event_nonblock, ZOOM_connection_process,
67 ZOOM_connection_get_{socket,mask,timeout},
68 ZOOM_connection_fire_event_{timeout,socket}.
69 The existing blocking event handler, ZOOM_event, is a wrapper for the
70 + blocking ZOOM_event_sys_{poll,select}.
72 Implemented function ccl_xml_config which parses XML version of CCL
73 configuration (bug #798).
75 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
77 Added timings utility (yaz/timing.h)
81 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
84 Fixed bug #779: Rotation of apdu.log fails.
86 Fixed for character set conversions:
87 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
88 Honor G1 set in MARC-8 decoding.
92 Fixed bug #775: char conversion does not handle Alternative UTF-8
95 Implemented function yaz_marc_read_line which parses MARC line format
96 records. There is a wealth of formats out there. So far, this function
97 reads line records produced by yaz_marc_write_line.
99 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
100 more generic and easier to remember(!) options: -i format and -o format
101 which specifies input format and output format respectively - where
102 format is one of "marc", "marcxml", "line", "marcxchange".
104 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
105 does not print anything except warnings for records.
107 For yaz-marcdump, added support for MARC split into files (-s) with a given
110 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
111 spec, at http://www.loc.gov/standards/sru/record-update/
112 This has changed the binary layout of the following structs:
113 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
114 bend_update_rr . Patch by Ko van der Sloot.
116 Added GFS utility function bend_assoc_is_alive which returns 1 if
117 association is still alive (client is connected); 0 otherwise (client
118 closed connection). This allows busy servers to stop working for
121 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
122 been a separate piece of software. This version of ziffy has been modified
123 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
125 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
127 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
128 Client code may now interrogate options such as "init_opt_sort" to
129 find out whether the server claims to support various options.
131 --- 2.1.40 2006/11/27
133 Added utilities yaz_{set,get}_esn to set/get element set name from
136 Removed the build of libyazthread.la. The libyaz.so is the threaded version
137 of YAZ and has been so since YAZ 2.1.10.
139 Implemented ZOOM_record_error which returns error information for
140 record (surrogate diagnostic).
142 --- 2.1.38 2006/10/31
144 Updates for SRU Update by Ko van der Sloot:
145 1. Changed name from "operation" to "action"
146 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
147 versions in the code, marked as 'backward compatible'.
148 3. Added diagnostics for SRU Update.
150 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
152 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
154 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
156 For GFS, fixed problem with SRU diagnostic 'First record position out of
157 range' being issued for 0 hits.
159 zoomtst10 part of Windows Build.
161 --- 2.1.36 2006/10/13
163 Implemented yaz_filepath_comp which splits a path into file path
164 components (required by Zebra 2.0.3+).
166 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
167 BSD inspired license until now so this should not have any real impact on
168 anybody. See http://www.opensource.org/licenses/bsd-license.php
170 Fixed bug #687: Missing log lines.
172 Fixed bug #678: CQL to PQF translation does not preserve double-quote
175 Fixed bug #689: SRU diagnostics to be added.
177 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
178 whether a connection is idle (no more work do do).
180 --- 2.1.34 2006/10/04
182 Change type of optval from long to int for invocation of setsockopt with
183 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
185 Added support for specifying the max log file size for the Generic
186 Frontend Server. The size is given with option -r.
188 --- 2.1.32 2006/09/21
190 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
192 --- 2.1.30 2006/09/17
194 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
197 Fixed bug in Generic Frontend Server that could cause a server to stop
198 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
200 For the generic frontend server, the maximum record size is used as maximum
201 size of incoming packages (SRU + Z39.50). The value until was previously
202 only used in Z39.50 Init negotiation and, later, in a session controlled
203 sizes of records returned. This is controlled using -k option. It can be
204 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
206 --- 2.1.28 2006/09/04
208 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
211 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
213 New option for yaz-marcdump -lpos=value which allows setting a portion
214 of MARC header to a certain value.
216 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
218 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
219 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
221 --- 2.1.26 2006/08/15
223 Fixed problem with SRU mode type (soap, get, post) for yaz-client
226 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
228 --- 2.1.24 2006/08/08
230 Fixed MARC ISO2709 encoding routines to deal with character set
233 Minor changes to GFS logging. Database included in search request log
236 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
237 cached/multiple records.
239 Shared libraries are built by default on Unix+configure.
241 Changed cql2pqf transformation to use a different evaluation order. The
242 new order is: always, relation, structure, position, truncation, index
243 and relationModifier. Old order was: always, relation, relationModifier,
244 structure, index, position, truncation. Note that the the latter ones
245 override former ones for identical attributes.. The new scheme means that
246 it is possible to override any existing attribute with a relationModifier.
247 And also that it is possible to override everything for the index rule
248 (except the ones listed in relationModifier). No order is perfect but this
249 one, we believe, covers more real cases.. The "always" should have been
250 called "default", since the attributes there can be overridden with all
253 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
254 compilation phase, but also for yaz-config --cflags output. This allows
255 us to have public headers with Libxml2 stuff in them . It should also,
256 eventually, make Libxml2 checks redundant in packages using YAZ, such
259 --- 2.1.22 2006/06/15
261 Changed SRU update structure bend_update_rr so that SRU diagnostics are
262 stored in uri, message and details.. Previously diagnostics were stored
263 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
264 compatibility.. but he's probably the only one affected, so.
266 Added support for CCL, compiled on the client side, in ZOOM-C. This
267 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
268 input; the resulting query objects can be used for for searching with
269 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
271 YAZ' configure searches for OpenSSL by default.
273 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
274 SL_CTX_use_certificate_file. See
275 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
276 for more info. Thanks to Ko van der Sloot.
278 --- 2.1.20 2006/06/02
280 Bug #600: SRU GET, POST support for yaz-client. Introduced
281 command 'sru' which selects method SOAP/GET/POST.
283 Allow missingValueAction to be specified for the sortspec string -
284 function yaz_sort_spec. By default, the missing value action is null.
285 Use ! to specify "abort". Use = followed by stringvalue to specify default
288 Ensured that Present-handler (if defined) is called in GFS before any call to
289 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
290 searchRetrieve requests.
292 Documentation for YAZ is now based on the Docbook XML/XSLT using
293 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
294 is no longer depending on jade/openjade or docbook-to-man scripts.
295 PDF is no longer part of the distribution - but can optionally be
296 made using DSSSL/jadetex or FOP.
298 Added retrieval handling support in Generic Frontend Server to support
299 conversion between MARC/XML as well as XSLTtransforms. See
300 etc/yazgfs.xml for an example.
302 Added Authentication support to Generic Frontend Server in SRU
303 mode. Authentication using HTTP Basic is supported, as is the use
304 of 'x-username' and 'x-password' parameters in the request itself.
306 Added support for a new character set MARC8s identical to MARC8 except
307 that it converts combined characters to single Unicode characters in the
308 Latin-1 range (when possible).
310 --- 2.1.18 2006/04/24
312 ASN.1 compiler 0.4: generates brief Doxygen file header for
313 generated .h/.c files.
315 Utility yaz_iconv now supports conversion to MARC-8.
317 New facilities for the MARC module. The reading - and writing of
318 content are separate methods for the yaz_marc_t handle. The following
319 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
320 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
321 format). Write functions have prefix yaz_marc_write_.. The existing
322 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
323 available. Removed support for OAI-MARC and simplexml (not the
324 simplexml from PHP5).
326 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
327 to be returned for this connection.
329 --- 2.1.16 2006/03/31
331 Allow multiple languages and charsets to be specified with
332 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
333 negcharset iso-8859-1,utf-8
335 Translation of proximity nodes from CQL into PQF now works.
337 Moved to automake 1.8, 1.9.
339 Added function yaz_log_set_handler which allows a log handler to be
340 installed. This handler will be called for all log messages. Output
341 to file is also produced; but that can be disabled by passing NULL
342 fname to yaz_log_init_file.
344 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
346 For SRW (including GFS), accept application/soap+xml as content-type
349 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
350 produces NO stylesheet reference even if a default stylesheet is specified
353 --- 2.1.14 2006/03/14
355 Updated Windows package to include yazd.dll + yazd.lib for the
356 Development component.
358 If the environment variable YAZ_LOG is set, then it is used as a
359 string indicating the default level of logging to use if not
360 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
361 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
362 used as before. So, for example, to omit warnings from YAZ logging,
365 cql_transform() now map structure and other attributes before indexes,
366 so that index-specific structures and other attributes can override
367 defaults. So now a combination of mapping specifications such as:
369 index.dc.date = 1=date-modified 4=5
370 does the right thing.
372 cql_transform() now also respects the "always" mapping specification,
373 which establishes an initial set of attributes to be used for all
374 terms except where overridden by more specific attributes associated
375 with the index, relation or modifier.
377 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
378 which mode to use; one of "post", "get" or "soap" (SRW, default).
380 Fixes for yaz_iconv routines: changed trie-based character set conversions
381 to use only non-negative values for bit fields due to Sun's C compiler not
382 supporting negative values.
384 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
385 sequences where not read correctly. Fix by Rustam Usmanov.
387 Updated win/makefile to use options, settings which makes things
388 compile with VS C 2005.
390 --- 2.1.12 2006/02/01
392 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
394 In ZOOM socket code, use select instead of poll on MacOSX.
396 ZOOM-C now support client-side compilation of CQL into RPN that is
397 sent to the server, enabling CQL to be used against all Z39.50
398 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
399 ZOOM_query object, and submit it using ZOOM_connection_search().
400 The CQL-to-RPN translation uses a configuration file, the name of
401 which must be specified in the Connection's "cqlfile" option.
403 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
404 function, which takes as its start-term parameter a ZOOM_query object
405 (which may have had either CQL or RPN set into it).
408 --- 2.1.10 2005/11/29
410 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
411 GFS to support this as well. Backend handler, bend_srw_update, does the
412 update work. Code contributed by Ko van der Sloot.
414 Allow retrieval of Search Result-1 information in ZOOM by the use of
415 options that are attached to a result set. ZOOM documentation updated
418 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
419 UTF-8 conversion. Patch by Raj Patel.
421 Added option -m to GFS to control formatting of timestamps in log file.
423 Added 'exit' as synonym for 'quit' in yaz-client
425 Added support for specifying SRW resultSetId + resultSetIdleTime in a
426 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
427 for the new members. Patch by Ko van der Sloot.
429 Added support for SRU POST. It is supported for content-type
430 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
432 Do not build the separate Multi-threaded (MT) library libyazthread.la.
433 Instead make the library libyaz.la multi-threaded. Threading as a whole
434 can still be disabled by configure option --disable-threads. Previosly,
435 with older GLIBCs there were problems with MT libs under Apache. This
436 has now been fixed a long time ago.
438 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
441 CQL module modified to be case insensitive for relations/indexes/operations.
443 Fixed bug in CQL transform code: incorrect value relationModifieder
446 Added 'show all' command for yaz-client which retrieves all results
449 Added new yaz-client, xmles, which takes a (private) OID and
450 a document to be sent as an extended service request.
452 Describe new yaz-client commands wait_response and set_auto_wait.
454 Increase TCP/IP listener backlog from 3 (which I am guessing was
455 copied from the SunOS manual entry way back when) so SOMAXCONN, so
456 that the socket will queue as many incoming connections as it's able
457 to handle ongoing connections. In other words, it will never now
458 refuse a connection that it would be able to handle merely because
459 it's not got around to accepting() enough of the pending connections
460 yet. This is the behaviour anyway under Linux, where the listen()
461 argument is ignored; but not under BSD and on systems such as
462 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
463 YAZ-based servers should now be uniform across operating systems in
466 yaz-marcdump uses 64-bit file access on some systems. This is enabled
467 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
468 This allows yaz-marcdump to read large MARC batches (>2 GB).
470 Modified all YAZ source files - except the source which is auto-generated
471 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
474 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
475 corresponding to the existing *_setl() function. These allow option
476 values containing arbitrary valuues.
478 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
479 ZOOM_resultset_sort() in new applications. Its behaviour is identical
480 except that it returns an indicator of whether or not the sort
481 criterion was accepted (0 for OK, -1 for invalid).
485 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
486 MARC output rather than returning "new" buffer.
488 yaz-client warns about unknown init options.
490 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
494 Added support for SRW sort in Generic Frontend Server. Patch
495 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
496 sortKeys - or NULL if none is provided.
498 Fixed bug #307: It was impossible to specify indefinite/no timeout
499 for ZOOM_event. Special timeout value -1 now means indefinite timeout
502 Added support for multiple languages and charsets to be specified in
503 ZOOM. Each charset/language is separated by a blank. If negotiation is
504 in effect in init-response, Option
505 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
506 Code based on patch by Vasiliy Osadchuk.
508 Fixed bug #306: infinite recursion that occurred when calling
509 yaz_log_level_init as the first call (before other log level or
512 Fixed bug in scan handling in front end server: if preferred-Position-In-
513 Response was non-present, a NULL pointer referece was performed.
517 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
518 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
519 now defined for all those error codes. So instead of putting 109 in
520 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
521 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
523 Modified the yaz-marcdump utility to skip garbage bytes between MARC
526 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
528 Program yaz-client now exits and produces an error message if multiple
529 Z39.50 servers are specified on the command line (none or one allowed
532 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
537 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
539 Fixed bug #272: Preserve spacing for CCL terms.
543 Added support for virtual hosts and multiple backend servers for
544 the YAZ frontend server. The configution is XML based and
545 support specificition of CQL to RPN mappings and explain information.
546 See section "Virtual Hosts" in the YAZ manual.
548 Extended OPAC display utility. OPAC display utility renders
549 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
550 to supplement yaz_marc_decode_wrbuf.
552 Fixed a bug in MARC decoder that could caused it to crash for some
553 invalid MARC records. More diagnostics and warnings where added in
554 XML output (warnings, etc are stored in comments).
556 --- 2.0.34 2005/02/08
558 Fixes for UNIX domain sockets. Bug #261.
560 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
562 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
563 Added yaz_marc_subfield_str which defines subfield lead string which is
564 used in YAZ_MARC_LINE format. Default string is blank+$. Added
565 yaz_marc_endline_str which defines end of fields string used in
566 YAZ_MARC_LINE format. Default string is newline.
568 Experimental support for MarcXChange. This format can be produced
569 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
570 http://www.bs.dk/standards/MarcXchange.xsd
572 Added yaz-client commands scansize that sets maximum number of
573 entries to be returned by scan.
575 --- 2.0.32 2005/01/11
577 Added support for SRW scan in yaz-client and Generic Frontend Server.
579 * Added whereInList member to SRW Scan Term.
581 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
583 Fixed NMEM system to return aligned blocks on the smallest boundaries
584 that are suitably aligned for all possible types on the particular
585 architecture YAZ is being built for.
587 --- 2.0.30 2005/01/04
589 Fixed numerious warnings that was issued with newer versions of GCC.
591 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
592 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
595 Make YAZ Generic Frontend Server slightly faster.
597 Enhance (and reduce) logging for Generic Frontend Server.
599 Revert YAZ log system so that it flushes every write operation
600 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
602 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
603 instead of LOG_, due to name clash with syslog(3). LOG_ are still
604 present. New applications should define YAZ_USE_NEW_LOG=1 - this
605 will effectively disable old definitions.
607 --- 2.0.28 2004/11/09
609 Added yaz_log_time_format which specifies log format using
612 Added yaz_log_module_level which returns mask for a module. Value
613 is non-zero mask a if module is enabled; zero if disabled.
615 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
616 in include/yaz/cql.h.
618 Fixed bug #176: Dont throw diagnostics on empty SRU args.
620 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
622 Fixed bug #172: RPM builds does not enable SSL.
624 Doxyfile.in part of dist. Doxyfile generated by configure.
626 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
627 are given and the corresponding component does not exist.
629 Extend CCL documentation in YAZ reference. Describe r=r.
631 --- 2.0.26 2004/10/01
633 Fixed MARC->MARCXML conversion to properly deal with
634 fields, subfields, indicators having non-ASCII characters.
636 Fixed MARC->MARCXML conversion so that ASCII control characters
637 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
640 Added YAZ GFS support for conversion from Z39.50 surrogate
641 diagnostics to SRW surrogate diagnostics.
643 Bug fix: YAZ GFS did not return schema in explainResponse.
645 --- 2.0.25 2004/09/30
647 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
648 now converts recordSchema to elementSetName as well as schema URI.
650 Fixed bug in COMSTACK that prevented HTTP request packages from being
653 --- 2.0.24 2004/09/29
655 Added CCL facility r=r "range" which is similar to r=o "ordered" but
656 does not require white-space before and after the dash in a range, e.g.
657 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
660 Fixed a few AC_TRY_LINK configure tests that did not operate properly
661 due to new GCC removing "redundant" code.
663 Added yaz-client commands scanpos and scanstep that sets preferred
664 position and step-size for scan.
666 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
668 Added CCL utility ccl_qual_buf which parses one or more CCL
669 spec lines in a buffer.
671 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
672 of name and value - ignoring empty lines and comments.
674 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
676 Added odr_get_element_path which returns current element path for an
677 ODR handle. This utility is useful in error handling or user-defined
680 Added ODR_PRINT utility odr_set_stream which is is a more generic
681 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
682 to a write function and pointer to close function. The close function - if
683 non-NULL - will be called during odr_destroy.
685 Fixed bug in CCL parser where truncation char was not removed from
686 right side when truncation=both was in effect.
688 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
691 --- 2.0.23 2004/08/11
693 Fix buffer overrun in CQL parser when dealing with proximity (%).
695 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
696 to UTF-8/UCS conversion is now only based on codetables.xml.
698 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
700 --- 2.0.22 2004/08/06
702 Add support for more "commit changes" in ZOOM (uses Extended Services).
704 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
707 Yet another small fix for configure of SSL.
709 --- 2.0.21 2004/05/14
711 Fix SSL libs for configure when --with-openssl=DIR is given.
713 --- 2.0.20 2004/05/10
715 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
717 SSL comstack now uses yaz.pem certificate file on server side
718 by default. Certificate filename can be configured by calling
719 comstack function cs_set_ssl_certificate_file before cs_bind is used.
721 Fix bug regarding multiple calls to ZOOM_connection_connect.
723 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
725 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
726 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
728 ZOOM now allows inspection of X509 peer certificate for verification.
729 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
731 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
732 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
733 as "modular" but it simplifies things.
735 Added cs_get_peer_certificate to that returns peer X509 PEM.
737 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
738 NULL if SSL is unavailable.
740 Documentation about MARC decoding tools.
742 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
744 --- 2.0.19 2004/03/30
746 Rename CHANGELOG to NEWS to follow GNU style packing.
748 Fix bug with missing initialization of member in init_diagnostics.
749 This bug affects threaded version of GFS server.
751 --- 2.0.18 2004/03/20
753 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
756 Ensure zlib.dll is packed with Windows install.
758 --- 2.0.17 2004/03/17
760 Fix encoding of xsd:string to use text instead of CDATA.
762 Fix endless loop in CQL parser with unbalanced ".
764 Use a more compact way to store MARC-8 conversion tables.
766 --- 2.0.16 2004/03/16 Debian only
768 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
771 Update CQL parser to use new CQL 1.1 modifiers for booleans and
776 --- 2.0.15 2004/03/01
778 Another fix for decoding of XML packed records.
780 --- 2.0.14 2004/02/25
782 Fixes for Chunked encoding. White space not ignored after length spec.
784 Update NS and use default NS for SRW diagnostic elements.
786 --- 2.0.13 2004/02/23
788 Implement ZOOM_resultset_cache_reset which resets record cache.
790 Implement ZOOM_resultset_sort which sorts a result set.
792 Implement chunked HTTP transfer.
794 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
796 --- 2.0.12 2004/02/16
798 Added member 'schema' to bend_explain_rr structure so that backend
799 can specify explain record identifier. Defaults to Zeerex 2.0.
801 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
803 --- 2.0.11 2004/02/16
805 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
808 Added init command for yaz-client which sends "extra" init request.
810 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
811 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
813 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
815 Make ZOOM error code for "invalid query".
817 Fixed compilation for SSL which wasn't properly enabled for all platforms.
819 --- 2.0.10 2004/02/05
821 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
824 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
826 Added option -p <file> to make Generic Frontend Server to write PID file.
828 Added option -D to put Generic Frontend Server in background on its own.
830 Make ZOOM C recognize option "password". If unset, "pass" is used
831 (for backwards compatibility).
833 Fixed a bug in Generic Frontend Server that could make it crash if a
834 client sets characterSetNegotation bit, but didn't pass negotiation stuff
837 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
838 Must be issued before open, in order to be in effect.
840 --- 2.0.9-6 2004/01/12 Debian/Windows
842 Make the SRU server more picky WRT unknown params, etc.
844 Bug fix: ZOOM scan response didn't return displayTerm - when present.
846 New YAZ client command, options, that sets Z39.50 options.
848 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
849 options from a string of tokens (one token for each option bit).
851 Update SRW diagnostic code messages.
853 --- 2.0.9-5 2004/01/07 Debian/Windows
855 Handle user defined stylesheet for SRW/SRU.
857 --- 2.0.9-4 2004/01/06 Debian/Windows
859 Fix bug in decoding of Content-Length.
861 --- 2.0.9-3 2004/01/06 Debian/Windows
863 Fix a bug with decoding of XML packed records.
865 --- 2.0.9-2 2004/01/05 Debian only
867 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
869 Fix bug in SRW/SRU diagnostics decoding.
873 Fixed bug in Generic Frontend Server which could drop records exceeding
874 preferred message size. Reported and fixed by Irina Dijour.
876 Fixed calculation of package size for structured records in Generic
877 Frontend Server. Reported and fixed by Irina Dijour.
879 Fixed namespace for SRW/SRU diagnostics.
881 Fixed SEGV in yaz-client that occured for HTTP connection errors.
885 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
886 this version is incompatible with version 1.0 and older YAZ SRW/SRU
889 CQL changes to reflect recent changes to the specification:
890 * Documentation talks about context sets instead of index sets.
891 * Documentation talks about indexes instead of qualifiers.
892 * The CQL-to-PQF transformer's configuration file now uses
893 "index.set.name = <attributes>" instead of the old form
894 "qualifier.set.name = <attributes>". (Both forms are still
895 understood but the latter is deprecated.)
896 * CQL terms with no explicit index specified are now interpreted as
897 cql.serverChoice instead of srw.serverChoice (which of course
898 behaves exactly the same.)
902 MARC conversion can now generate ISO2709 output in another
903 character set. yaz-marcdump uses this facility if you invoke it
906 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
907 functions from there can be used from C++.
911 Frontend server now transfers memory from decoded packages to stream
914 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
915 references to show up.
917 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
918 the ZOOM Abstract API. The older names for the same options are still
919 also supported for the benefit of old applications.
921 ZOOM-C supports "implementationId" and "implementationVersion" options
922 to go along with "implementationName". These allow the user code to
923 specify identification strings to be sent to servers.
924 Add OID for the new ExtLite attribute set.
926 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
927 as requested/supplid by Ere Maijala <ere@atp.fi>
929 For generic frontend server, reverse the order of
930 "toolkit-supplied / application-supplied" strings sent as implementationId,
931 Name and Version. Also, remove the spaces around the slash. This brings
932 the GFS in line with the behaviour of ZOOM-C on the client side.
934 Add function ZOOM_scanset_display_term.
936 yaz-client shows scan displayTerm if present.
938 Utility yaz-iconv is now installed by default along with the man page
941 Extend configure check for OpenSSL to use pkg-config where available (such
944 Incorporate patch by Morten Bogeskov which allows a Unix file socket
945 server to specify uid/gid/mask for socket using the format
946 unix:[user=uid,][group=gid,][umask=mask,]file=path
947 If file= is omitted the existing format is assumed, e.g.
949 in which case the mask is 0666 (rw for everybody).
951 Major restructure of YAZ source. All source in libyaz is in src directory.
952 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
953 util (utility programs such as ASN.1 compiler, yaz-marcdump).
955 Added man page for utility yaz-marcdump (used to be called marcdump).
956 yaz-marcdump is installed by 'make install'.
958 Fixed a memory leak in Generic Frontend Server that occurred when decoding
959 of incoming package failed.
961 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
963 Change prototype of odr_perror: add const to message string.
965 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
967 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
968 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
969 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
970 DNS lookup. There should not be any compatibility problems with this
971 assuming that blocking=1 or 0 is used.
973 Fix bad reference in UNIX comstack in function cs_addrstr.
975 Fix for compilation on AIX.
977 The generic front-end server (server/seshigh.c) now supports returning
978 Init diagnostics to the client in User-information-field, in
979 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
984 Allow any CQL relation (not just all,any,exact,scr).
986 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
987 that features the same UI.
989 Implemented command update0 in YAZ client which is equivalent to
990 update but uses old of Ext Update ASN.1.
992 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
993 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
994 Previously no OID was used for this info.
996 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
997 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
998 returns 'malformed search term' otherwise.
1000 SortResponse member resultCount now set to NULL in sort handler of
1003 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1006 Add three new utility functions for translating OIDs between various
1007 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1008 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1009 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1010 char *oid_to_dotstring(const int *oid, char *oidbuf);
1011 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1013 Reverted modifications for ES Update definition for z_IU0Update
1014 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1015 is back to YAZ 2.0.2.
1017 String value attributes for CCL parser.
1019 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1020 which their FirstSearch server returns in Init responses, sometimes
1021 carrying useful diagnostic information when Init fails. This has the
1022 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1023 "z39.50/oclcui.asn", where its definition is somewhat different from
1024 what OCLC document on their web-site, as required to interoperate with
1027 Support for anonymous authentication in yaz-client. Use the command
1030 * Fix the OID of the Index Data-local "admin" Extended Service from
1031 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1032 the 1000, which indicates a locally-defined OID, was a mistake.
1034 --- 2.0.3 2003/06/20
1036 Fix CCL directive @case handling so that it affects string match for
1037 both CCL keywords and qualifiers.
1039 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1040 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1041 Decoder has been updated with ASN.1 changes as listed in
1042 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1043 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1044 z_IUUpdate, remains unchanged.
1046 ZOOM_record_get may now return a record in a specific character set.
1047 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1048 "from" is the character set of record as returned by target. "to" is
1049 the character set to be returned. If omitted, "to" is UTF-8.
1051 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1053 New ODR utility, odr_getelement, which returns name of element for
1054 which encoding/decoding failed.
1056 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1057 in cases where a required element was omitted.
1059 Bug fix: some MARC8 sequences were not converted.
1061 New ZOOM option "step" which specifies number of records to be
1062 retrieved in one chunk. Used in conjunction with "start" and "count".
1064 SRW support for yaz-client. Use scheme http: to use it, e.g.
1067 yaz-client no longer does (un)intelligent character set conversions
1068 by default. Can be enabled with charset and marc_charset commands.
1070 xmalloc trace fix for 64-bit systems such as DEC alpha.
1072 Solaris 2.6 compile fix.
1074 New function, cql_strerror() translates SRW error codes, as returned
1075 by cql_transform_error(), into human-readable English strings. Used
1076 in yaz-client diagnostics when appropriate.
1078 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1079 converts it into a type-1 query which is sent to the server. This
1080 makes CQL available for use with all Z-servers, as opposed to the tiny
1081 minority that can handle CQL queries themselves.
1083 --- 2.0.2 2003/04/28
1085 New Debian package layout similar to the Redhat Package layout.
1087 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1088 and search result respectively.
1090 --- 2.0.1 2003/04/25
1092 Redhat package is now several packages: libyaz (runtime libraries),
1093 libyaz-devel (development and documentation, and yaz (utility programs).
1094 Package spec file by Morten Bøgeskov.
1096 New member 'schema' in struct bend_fetch_rr which the name of requested
1097 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1098 handler MAY set this to reflect the schema of the returned record.
1100 New member 'display_term' in struct scan_entry. GFS now sets member entries
1101 and allocates scan entries to be filled by user scan handler. In previous
1102 version, entries member was allocated by the scan handler. That still works,
1103 but the GFS will ignore member display_term - assuming it was NOT set by
1104 the handler. The fact that the GFS now allocates the entries both allows
1105 for new members and makes a scan handler easier to write.
1107 Fix CQL lex buffer overflow.
1109 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1110 SRU default recordPacking is string.
1112 SRU protocol support for frontend server.
1114 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1116 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1118 Added scan for the ZOOM shell (zoomsh).
1122 * String Identifers for Schemas (Amendment 5).
1123 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1124 Old definition for schema
1125 Odr_oid *schema; /* OPT */
1130 Z_InternationalString *uri;
1131 #define Z_Schema_oid 1
1132 #define Z_Schema_uri 2
1135 * resultCount parameter to Sort Response (Amendment 1).
1136 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1138 Support for SRW 1.0 over HTTP. This is an optional feature and
1139 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1142 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1143 on the same port. SRW SearchRetrieveRequests are mapped
1144 to bend_init,bend_search,bend_fetch,bend_close.
1146 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1148 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1149 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1151 ZOOM connections are SRW based if schem http is used for hostname
1152 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1153 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1155 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1156 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1157 distance=n, order=true/false, relation=le, prox unit=word. If
1158 n is omitted, distance 1 is used.
1160 Fixed problem with C compiler include path in wrong order.
1162 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1163 on Solaris. Patch from Ko van der Sloot.
1165 New MARC decode API. All new functions operate on a yaz_marc_t
1166 handle. The most important new functions are: yaz_marc_create,
1167 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1168 decode and destroy respectively. Decoder can produce formats
1169 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1170 include/yaz/marcdisp.h.
1172 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1173 to UTF-8, UCS-32, wchar_t or Latin-1.
1175 * Prototypes for yaz_iconv_-functions moved to separate header
1176 include/yaz/yaz-iconv.h.
1178 Make a few private functions 'static' in unix.c. This prevents
1179 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1181 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1182 are set when Init Response is received.
1184 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1185 but returns diagnostic set as well.
1187 New function yaz_strerror which is a portable wrapper for
1188 strerror/strerror_r/GetLastMessage.
1190 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1191 is returned for MARC. If type is "oai", then OAI MARC is returned.
1193 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1196 --- 1.9.2 2002/11/26
1198 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1200 Fix bad race conditions on SIGTERM and terminate gracefully in
1203 Move retrieval (data1) module to Zebra since nobody seems to be
1206 Add GRS-1 render for ZOOM using same format as yaz-client.
1208 --- 1.9.1 2002/10/05
1210 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1212 Fix broken ESpec handling in data1 module.
1214 SGML reader parses comments and makes them part of the data1 tree.
1216 Added several type casts so that YAZ compiles as C++ code.
1218 ZOOM didn't handle PDU encoding failures properly.
1220 Added more Bib-1 diagnostics (approved extensions).
1222 GNU configure: better check for iconv.
1224 More portable use of accept, getpeername. Check for socklen_t. Use
1225 int/size_t if socklen_t is not defined.
1229 PQF parser rejects bad queries - including those with extra
1230 characters in them. PQF parser used to silently ignore that.
1231 Cleaner API for PQF added, which allows you to get detailed
1232 error information for bad queries (see yaz/pquery.h).
1234 Fixed bug in ZOOM_record_get for type "database".
1236 Implemented mini iconv library supporting conversions between
1237 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1239 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1241 --- 1.8.9 2002/08/20
1243 Fixed ZOOM C record cache so that preferredRecordSyntax and
1244 elementSetName is used to check for already fetched records.
1246 --- 1.8.8 2002/08/02
1248 Added three members in bend_initrequest structure to facilitate
1249 character set negotiation.
1251 Fixed a bug in frontend server that could cause indefinite
1252 loops under rare conditions.
1254 Revised character set utilities (charneg.h) so that encoding
1255 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1257 For PQF, directive @term <type> sets term type for Scan/Search.
1258 Here <type> is general, string, numeric, null. The term type
1259 is inherited - just like @attr.
1261 New call odr_set_charset that sets character set conversion for
1262 international-strings on a ODR stream. Prototype is:
1263 int odr_set_charset(ODR o, const char *to, const char *from);
1264 The InternationalString is still represented as C string in YAZ
1265 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1266 won't). On the protocol level, you can use any encoding.
1268 Support for UNIX sockets in ZOOM.
1270 Solaris recv sometimes returns errno == ENOENT. It is treated as
1271 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1273 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1274 both client and server. Code by Morten Bøgeskov.
1276 --- 1.8.7 2002/05/22
1278 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1279 that they can be used directly from Visual Basic. You must recompile
1280 your windows APP if you're using ZOOM.
1282 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1283 Commands "lang" and "charset" sets language and character set respectively.
1284 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1285 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1287 Attributes from multiple CCL fields may be OR'ed rather than merged
1288 using directive "@field or". Fields are still merged by default -
1289 equivalent to "@field merge".
1291 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1294 Fixed bug in zget for parameter ExtendedServicesResponse.
1298 --- 1.8.6 2002/03/25
1300 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1302 Client displays USR.1:SearchResult-1 (hits per term).
1304 Additional Search Info for search in Generic Frontend Server.
1306 Fixed CCL parsing of "field=s".
1308 WIN32 installer - using the excellent NSIS software from nullsoft.
1310 Fixed CCL parsing of "field = - <number>".
1312 Added function yaz_marc_decode that decodes MARC for line mode
1313 display or XML (similar to that used by JZKit).
1315 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1316 Z39.50. But ISO/ILL was, however.
1318 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1319 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1322 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1324 --- 1.8.5 2002/02/03
1326 New YAZ client features: Command completion and new commands:
1327 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1328 Code provided by Jacob Poulsen.
1330 New call oid_trav, that visits all registered OIDs via callback.
1332 Function ZOOM_record_get now returns const char pointer rather than
1333 void pointer. It saves a lot of type casts.
1335 For YAZ client, command "auth" now allows you to set authentication
1336 in IdPass style. It is enabled when three tokens are given - order
1337 is user, group and password.
1339 Fix memory leaks in MARC record handling for ZOOM.
1341 New option for YAZ client, -k <kilobytes> that sets
1342 maximum record size. Similar to -k option for generic frontend
1343 server and yaz-ztest.
1345 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1347 Prefix query parser reports "fail" when bad attribute set is given.
1349 Fix in MARC decoder. Proximity logging. Fix for attribute set
1350 in scan handler for server. Patches by Shigeru Ishida.
1352 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1355 Configure option --with-openssl=<dir> now works when a directory is
1356 specified. Patch provided by Morten Bøgeskov.
1358 New option for YAZ client, -u <auth>, that sets authentication.
1360 ZOOM fix: error information was sometimes "missing", since error
1361 was cleared/reset too when it shouldn't.
1363 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1365 --- 1.8.4 2002/01/04
1367 Scan for ZOOM API. New object ZOOM_scanset. New functions
1368 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1369 ZOOM_scanset_destroy.
1371 New ZOOM function, ZOOM_connection_last_event, that returns type
1372 of last event (such as "receive data", "send data", "apdu received",
1375 New ZOOM option, schema, that specifies schema for retrieval.
1377 New CCL feature. Qualifiers can be aliases for one or more
1378 other qualifiers (if more than one is given, OR is used).
1380 ZOOM uses named result sets if target supports it.
1382 Two new YAZ client commands: . (dot, which sources a script of YAZ
1383 client commands), and ! (to execute shell command.). Implemented
1386 Working on Debian packages.
1388 --- 1.8.3 2001/11/19
1390 YAZ client enables named result sets only if target supports it.
1392 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1394 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1395 with key="host" to get same result.
1397 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1398 Function Z3950_resultset_record(s) returns references to records
1399 "owned" by resultset. To become owner use Z3950_record_clone.
1401 Function z_ext_record handles Extended Services. Thanks to
1404 --- 1.8.2 2001/11/12
1406 CCL Parser fix: ignore token comma when dealing with and-lists.
1408 Documentation updates for COMSTACK.
1410 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1411 Changed prototype Z3950_records. For some functions, int parameters
1412 were changed to size_t.
1414 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1417 New MARC decode/display function, marc_display_exl, which properly rejects
1418 non-ISO2709 records. YAZ client uses it.
1420 --- 1.8.1 2001/10/29
1422 Fix bug: local attribute set wasn't set correctly in PQF strings.
1426 * Old Z39.50 codecs no longer supported.
1428 Added ZOOM C binding. See http://zoom.z3950.org/
1430 Renamed states for COMSTACKs to avoid confusion with events.
1432 Implemented cs_look and proper cs_rcvconnect.
1434 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1436 Configure detects POSIX threads on OpenBSD.
1438 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1439 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1441 When error is returned from present handler, non-surrogate diagnostic
1442 is returned in present response (and fetch handler is no longer called).
1444 * Minor adjustments to pquery parser (PQF). Token characters may be
1445 escaped by using backslash (C-style).
1447 PQF parser allows string attribute values to be specified. For @attr,
1448 non-numeric characters after the equal-sign are treated as strings
1449 (e.g. @attr 9=title).
1451 CCL trunction character may be defined (@truncation in file)
1453 * function zget_ExtendedServicesRequest sets waitAction to
1454 waitIfPossible (was wait).
1456 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1459 CCL operator names may be set in field definition files (CCL_bibset).
1460 See ccl/bib1 for an example.
1462 Fixes in ASN.1 compiler for C++ compatibility.
1464 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1465 and "op_or" to avoid conflict with C++.
1467 Fixed problem with GNU readline detection on Redhat 7.0.
1469 Added step-size for Scan backend handler.
1471 Fixed bug that made the frontend server crash when no attribute
1472 set was specified for scan.
1474 Front-end server automatically switches to original working directory
1475 when installed as an NT service. Previously -w had to be specified to
1478 Added extended attributes for retrieval module (data1), so that data1
1479 records carry d1_readXML/SGML attributes. d1_read also supports
1480 null-data rules ( <tag/>)
1482 On UNIX when POSIX threads are available, a separate library libyazthread
1483 is created. Programmers should link with that library and the yaz library
1484 when using threads. The reason for the split was that some applications
1485 on Linux, such as Apache, doesn't work well when using shared objects that
1488 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1489 (or any frontend server) in SSL mode by specifying ssl: followed by
1490 address. Only tested on UNIX.
1492 Added feature for CCL module. Virtual structure s=al or s=ol generates
1493 and-list and or-list respectively instead of phrase search.
1497 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1498 log_mask_str. This was done to avoid name conflicts with other libraries
1499 (such as other PHP extensions).
1501 Added raw OID member for preferred record syntax (request_format_raw)
1502 and returned record syntax (output_format_raw) for backend fetch method.
1504 Config file yaz-config now accepts options so that it returns specific
1505 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1507 Shared library support for UNIX using GNU libtool.
1509 * Modified backend interface. Request/Response struct's replaced by
1510 one read/write C struct. For example bend_fetchrequest and
1511 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1512 Every handler - even search has to be registered in bend_init
1513 handler. This means that the YAZ library no longer refers to
1514 external functions and it makes it possible to make the whole
1515 thing a single DLL/SO.
1517 Added Segment handler for backend server.
1519 Added Zmbol/Zebra administrative functions to YAZ client.
1521 Threaded frontend server on UNIX (when POSIX Threads are available).
1522 Starting the server with option -T enables multi-threading.
1526 Added configure option --enable-comp/disable-comp to control use
1527 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1528 located in sub directory asn.
1530 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1531 in ${exec_prefix}/bin along with the other programs yaz-client and
1534 GNU automake used to maintain makefiles.
1536 Added several OID's.
1538 Changed retrieval module so that we can load records with no abstract
1539 syntax defined. Tagpaths in these records are fully composed of string
1542 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1546 On UNIX, the generated makefile now supports a proper 'make install'.
1547 The prefix can be set via GNU configure to set the install location
1548 (default is /usr/local).
1550 * YAZ programs client and ztest were renamed to yaz-client and
1551 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1552 locations, such as /usr/bin,/usr/local/bin,etc.
1554 * YAZ Header files were moved from include to include/yaz. YAZ Header
1555 files are referred to as include <yaz/log.h> rather than <log.h>.
1556 The YAZ include path (-I ..) is therefore the same as before. Programmers
1557 should update their #include statements or use -Ipath/include/yaz
1558 instead. The main motivation for doing this change is that YAZ header files
1559 can be installed in "standard" locations /usr/include,/usr/local/include
1560 without introducing conflicts, since ALL YAZ header files are stored
1561 in subdirectory yaz (under /usr/include for example).
1563 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1564 rather than project/workspace files. We switched because project files
1565 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1568 Changed name of logging function, logf, to yaz_log, to prevent name
1569 clash with some math-log functions. The YAZ header log.h defines logf
1570 to yaz_log (#define) so there should be no incompatibilities by this
1573 Added bend_start/bend_stop handlers for server. These handler are
1574 called on start/stop of server. For windows they are called whenever
1575 a service is started/stopped.
1577 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1578 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1579 in util/yc.tcl. The auto-generated C code structures are, in a few
1580 cases, incompatible with the old decoders. There are differences in the
1581 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1582 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1583 The preprocessor variable ASN_COMPILED is defined when the compiled
1584 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1585 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1586 wish to use the old encoders/decoders you can specify --disable-yc
1589 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1590 version so that it supports both new - and old version of DB Update
1592 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1593 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1594 change. The name parameter can be set to 0 in which no name is specified
1595 for the construction. The macros odr_implicit and odr_explicit sets name
1596 parameter to zero for the construction involved. New macros
1597 odr_implicit_tag and odr_explicit_tag are similar to the others,
1598 except that a name parameter is added. For programmers' that don't use
1599 ODR they probably only need to change the call to z_APDU and z_External.
1601 Added access control facility by interfacing the TCP wrapper library.
1602 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1603 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1604 name of the daemon and enables the access control as specified in
1605 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1607 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1608 den Dool <H.M.vdnDool@kub.nl>.
1610 Added reference ID parameter to most functions in server API - refer
1611 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1613 Changed name of ccl library to libccl.a (was ccl.a).
1615 Fixed bug in decoder for Explain (Category TargetInfo).
1617 Added support for GNU readline in client. Thanks to Jacob Poulsen
1618 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1620 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1621 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1622 IMPLEMENTATION! This change was made to the development version before
1623 the ZIG decided to retract the amendment. If any users MUST be
1624 compatible with the original Update definition, PLEASE CONTACT US, and
1625 we will include a separate definition corresponding to the old Update
1626 ES. Note that because of the change to the ASN.1 of the
1627 TaskPackageRecordStructure we cannot define a single structure that
1628 will support both versions.
1630 * Added const modifier to buffer parameter for some ODR/BER encoding
1631 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1632 completeWAIS, odr_dumpBER.
1634 Fixed bug in client.c which caused a crash when a scanResponse didn't
1635 contain positionOfTerm.
1637 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1638 * will cause an error in a client if a non-YAZ target sends both a
1639 * list of Scan entries and non-surrogate diagnostics.
1641 Retrieval module enhancements. Tag sets may be typed in the reference
1642 to it. From the .abs-file the "tagset" directive takes a third optional
1643 integer type for the tag set referenced. From a .tag-file the "include"
1644 directive takes a third optional type as well. The old "type" directive
1645 in the tag set itself is still recognized but acts as the default type
1648 Backend interface change. Individual Scan terms returned from bend_scan
1649 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1650 in include/backend.h.
1652 Retrieval module enhancements. Multiple tag sets and attribute sets may
1653 be specified in abstract syntax specs. Revised the error/warning for
1654 logging messages reported by the retrieval module when reading the
1657 Object Identifier system (oid_..) changed. The API is backwards
1658 compatible but the oid-routines now allocates new OID's when needed.
1659 Raw OID's may be specified in oid_getvalbyname.
1661 YAZ now uses GNU configure to generate Makefile(s).
1663 * Minor changes in some of the member names of DeleteResultSetRequest and
1664 DeleteResultSetResponse. See include/proto.h.
1666 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1667 and added member 'languages' in TargetInfo (which was missing).
1669 Changed the way attribute sets are handled in the retrieval
1670 module. These are now cached, just like the abstract syntaxes
1673 Changed YAZ so that it links with compiled ASN.1.
1675 Added Explain-schema definitions and mapping routines. The following
1676 Explain categories have been implemented: AttributeDetails,
1677 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1679 Fixed minor bug in Windows version of Server Library.
1681 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1683 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1685 Added EXTERNAL: UNIverse Resource Report (non-standard).
1687 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1688 ENUMERATED and SET OF.
1690 * Added 'const' to some of the char pointer arguments for the
1691 functions, data1_read_node, data1_getelementbytagname,
1692 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1695 Fixed bug in data1_insert_taggeddata - the last_child member of
1696 parent wasn't initialised.
1698 * Changed data1_read_record and data1_read_node so that the supplied
1699 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1700 doesn't refer to any parts of the "SGML"-buffer.
1702 Fixed bug in server library (Windows version of statserv_remove).
1704 * Changed code so that it compiles as C++. The type definition
1705 of Odr_fun which is a member of Odr_arm was changed. The result is,
1706 that an explicit typecast is needed for the fun pointer when
1707 using Odr_arm - as in:
1708 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1710 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1712 Implemented the new structured date and time definition as approved
1713 by the ZIG. Added schemaId element to the specificTag in Espec-1
1714 (also approved at the last ZIG). Thanks to RVDM.
1716 Added some Object identifiers (RVDM).
1718 Changed the Update Extended Service (RVDM).
1720 Added command "refid" to client which specifies referenceId for
1721 the following requests.
1723 Implemented extended service handling for server. See ztest.c
1724 for an example as well as backend.h. New handlers are registerd
1725 in the Init handler.
1727 * Changed interface for sort in server.
1729 Added new members to statserv_options_block. It allows a server
1730 to read options from another source than just the command line. Thanks
1731 to Charles Woodfield.
1733 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1734 renamed to zboolean. Some C++ compilers complained about the name.
1736 Minor changes to gils.abs. Added index 's' (sort) on title
1737 and date/time-last-modified.
1739 --- 1.4pl2 1998/1/30
1741 Fixed bug in server library regarding inetd mode (-i). This bug
1742 was introduced by release 1.4.
1744 --- 1.4pl1 1998/1/29
1746 Added sort facility in client and backend server interface.
1748 Fixed problem with dependencies in Makefile(s).
1750 Fixed bugs for encoders/decoders of extended services and
1753 Implemented sub-tree feature for schemas. Sub-trees are
1754 referenced in *.abs-files. See explain.abs for an example
1755 of the use of this feature.
1757 Modified bib1.att; local attributes for ANY didn't include
1758 ANY itself (only affects use of the retrieval module).
1760 Fixed bug in plain SGML reader in function data1_read_node:
1761 tags with prefix "var" was incorrectly interpreted as variants.
1763 Added feature "sub-schemas" to enable references to - and definitions
1764 of - group of elements.
1766 * Removed member parent from type data1_element (in data1.h).
1768 Implemented function odr_nullval() that returns the value of
1771 * Removed member num_children from data1_node (in data1.h).
1773 Made NT service interface part of the server library. The
1774 function statserv_main uses the NT service when required and
1775 calls the statserv_start / statserv_close routines.
1777 Routine zget_SearchRequest and zget_PresentRequest fills
1778 resultSetName/Id member with "default" instead of "Default".
1780 Fixed memory leak in server. Request queue member wasn't freed.
1782 Fixed nmem_exit so that memory is freed.
1786 Revised the CCL parser utility to be thread safe.
1788 Added function, oid_ent_to_oid, to replace the function
1789 oid_getoidbyent, which is not thread safe.
1791 * Added nmem_init and nmem_exit to initialize and release
1792 NMEM resources. Function nmem_init should be called once in the
1793 initial thread before NMEM/ODR is used. statserv.c and client.c
1794 have been changed accordingly. The change was necessary to make
1795 NMEM thread safe. The NMEM memory pool is shared amongst threads
1796 in a process. Unix-based applications will still work fine without
1799 Added NT Services interface for the the Z39.50 (statserv) Server.
1800 Refer to the ztest.c source on the usage.
1802 Windows 95/NT port using MSVC5.0. Project files are included in the
1805 * Defined new 'global' handle for the retrieval (data1) system. The
1806 new handled, data1_handle, describes the state of the data1 system.
1807 This handle is passed as first argument to virtually all
1808 data1 related routines. The functions data1_create and data1_destroy
1809 creates and destroys a data1 handle respectively.
1811 Added ODR encode stream member to all backend request structures
1812 init, search, scan etc. This stream should be used to allocate all
1813 memory used for the response when thread safe operation is needed.
1815 Changed the comstack utility, cs_addstr, to be thread safe. The
1816 returned hostname string returned by the function is now part the
1819 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1820 function. The cs_straddr takes a COMSTACK handle as argument, so this
1821 function must be used after cs_create and before bind/connect.
1822 This function is thread safe.
1824 Moved test server to 'ztest' directory - generic server code still
1825 in 'server' directory.
1827 Made prefix query (pquery.c) utility thread safe.
1829 Added new function modifier YAZ_EXPORT to 'export' public DLL
1830 functions when using windows (see include/yconfig.h).
1832 Added definitions to the OID database (util/oid.c) (RVDM).
1834 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1836 Added call to ccl_rpn_delete in client program.
1838 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1839 release of RPN structure.
1841 Added support for C++, headers uses extern "C" for public definitions.
1842 With input from RVDM.
1844 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1845 Thanks to Ronald van der Meer (RVDM).
1847 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1849 Added support for private extensions to the OID database
1850 (oid_setprivateoids()). Thanks to RVDM.
1852 Added optional, physical ANY (key replication)
1854 Fixed null-reference problem in GRS-1 output filter.
1856 Proximity operator added to Prefix Query Format (PQF).
1858 In test client command "base" accepts multiple databases.
1860 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1864 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1866 Smallish bug-fixes in the new encoders/decoders (explain).
1868 Bug fixed in DeleteRequest.
1870 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1872 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1874 Added SOIF syntax (using private OID for now) to retrieval module and client.
1876 Added Update extended service.
1878 Added SearchResult-1 additional info structure.
1880 Added optional CCL (ISO8777) interpreter as separate module. Available
1883 --- 1.2 1996/6/10 (1st anniversary release)
1885 Added Summary record syntax. Lightly tested.
1887 Added OPAC record syntax. Untested.
1889 Added ResourceReport service encoders/decoders. Untested.
1891 Fixed bug in z_Unit - wrong tagging on unitSystem.
1893 Fixed bug in the DiagRecs decoder.
1895 Added options for max PDU size and session timeout to frontend-server.
1897 Added documentation of query-language parsers and other supporting utilities.
1899 [frontend-server] Added Attribute set to the bend_scanrequest API.
1901 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1902 surrogate diagnostics were generated.
1904 [retrieval] Allow multiple local values for attribute.
1906 [retrieval] Allow multiple attributes per element in .abs files. index type.
1908 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1910 --- 1.1pl2 1996/4/10
1912 Minor changes, mostly specific to Zebra's requirements (retrieval)
1916 Repaired bug in frontend server when running multiple listening
1917 endpoints in dynamic mode.
1919 z_External() now won't break if a known, ASN.1 value comes encapsulated
1920 in an octet-string. The value will pass through unmodified in an Odr_oct.
1922 Added a bit of code to the demo client to decode & display
1923 ASN.1-structured records represented in the octet-aligned branch of
1924 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1926 Added z_ext_getentbyref() to the ASN module. Doc updated.
1928 * Completed the SCAN definition in the ASN module. This may break SCAN
1929 code based on older YAZ-versions at compile-time. The fix is easy -
1932 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1933 under the SCAN definition. Remember to initialize this, server-people.
1935 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1936 that this does not extend to ODR and ASN.
1938 Comstack allows insertion of established socket (primarily for
1939 inetd-operation of servers). Doc updated.
1941 Front-end server can now start from the inetd in TCP mode. Doc
1944 --- 1.0pl4 1996/1/24
1948 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1949 the rank and record number.
1951 Adjustments to the frontend server.
1953 Fixed diagnostic BER dumper. It ignored the file argument.
1957 Various changes to retrieval module.
1959 Changed the union discriminators of the protocol files from enums to
1960 ints paired with #defines.
1962 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1965 *Changed operator in the RPN structure to 'roperator', again to avoid a
1968 Fixed problems in Explain decoders/encoders.
1970 --- 1.0pl2 1995/12/6
1972 Memory bug in log module fixed.
1974 --- 1.0pl1 1995/12/5
1976 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1978 Bug in Explain DatabaseInfo module fixed.
1980 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1984 The shift to v1.0 signals that we now consider the *core* functionality
1985 of YAZ reasonably stable (the core being more or less equivalent to
1986 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1987 tested (Explain not at all - though that will happen soonish).
1989 Minor changes to code to support Windows port.
1991 Various minor changes after we're getting to use GRS-1 & co. more.
1993 Added Espec-1 format.
1995 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1996 of the protocol and it cannot be selected when encoding (maps into 'string'
1997 when decoding). Needed to talk to some servers.
1999 Demo client can request simple element set names.
2001 Added Diagnostic Format encoders/decoders.
2003 Added simple Close handling to frontend server (no hooks for resource
2004 reporting yet), and demonstration client.
2006 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2008 --- 1.0b3 1995/08/24
2010 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2011 handled incorrectly when records were requested in the searchResponse. This
2012 will only affect you if you use the frontend-server.
2014 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2015 Test-client will ask for and print GRS1. Ztest will return dummy records
2018 Added Explain encoders/decoders to the service-level API. Untested.
2020 Added Extended Services: Item Order encoders and decoders to the Service-
2021 level API. Untested. We could use a recent copy of the pertinent bits
2022 of the ILL protocol to add those bits.
2024 Added diagnostic format 1 encoders/decoders to the service-level API.
2027 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2028 odr_cons.c, which causes a more correct output.
2030 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2031 was always set to 0 when no records were requested in the searchRequest.
2033 * Added better external-handling. This shouldn't harm old code that
2034 *encodes* externals. It can break code that looks for a
2035 'single-ASN1-type' representation, since those types that are known
2036 are now decoded immediately. Look at the SUTRS sample code in
2037 seshigh.c and client.c. Documentation updated.
2039 Handling of structured records in bend_fetchresponse. Length -1 marks
2040 structured record, type is deduced from format field.
2042 --- 1.0b2 1995/06/27
2043 Fairly quick maintenance release to add SUTRS support.
2045 Fixed handling of SUTRS records in the demonstration client.
2047 * Added format field to the bend_fetchrequest and bend_fetchresponce
2048 structures of the backend API (frontend server). When the record is
2049 returned, the value of the format field is mapped to an OID. The
2050 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2051 of the record. The special value VAL_NONE in the bend_request means
2052 that no specific format was requested by the client. Documentation
2053 updated accordingly. Test server (ztest) will return a fixed dummy
2054 SUTRS record if your client requests SUTRS.
2056 Documentation updated accordingly.
2058 You can now set external libraries and RANLIB support in the top-level
2062 First public release.
