3 Fix to ZOOM-C so that transparent reconnection is properly handled on
4 connections that are in asynchronous mode.
6 Fixed compilation on OpenBSD 4.0.
8 Large strings in GRS-1 records are now properly displayed in yaz-client.
10 Added character conversion support for "advancegreek"; based on patch from
13 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
14 sequence is met. Before the error was not set so it would be unknown.
16 Adjust yaz-marcdump MARC reader so that it skips until record separator
21 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
22 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
23 fd_set structure used as a bitmask for the FDs to be selected on.
25 Using ACX_PTHREAD macro to check for POSIX threads.
27 Fixed have-vsnprintf check.
31 Fixes for configure on BSD. Bug #900.
33 Added snprintf/vsnprintf wrappers for systems that don't have
34 limits (heavens forbid).
36 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
37 created before all previous tasks were completed and removed from the
38 task queue, the new task could be removed by a mistake.
40 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
42 Implemented pass-through CQL-to-PQF conversions. Bug #861.
44 Fixed bug #832: Problem with MARC/charset in yaz-client.
46 Fixed bug #668: save command line history for yaz-client.
48 Fixed bug #830: pkg-config support.
52 Extended ZOOM result set options with two options that may be read by
53 a client: resultSetStatus and presentStatus with values as specified for
55 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
57 Fixed bug #827: Using SSL fails on Debian etch.
59 Fixed bug #826: Weird looking chars for set of MARC records.
61 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
62 that is treated as an ItemOrder with itemRequest being an XML document
63 external. The value of "doc" is the content.
65 Extended the GFS search facility. New member of bend_search_rr
66 'estimated_hit_count' signals that hits is known to be an estmate
67 (higher or lower than real hit count). New member 'partial_resultset'
68 signals that the search was partial (hit count is lower or equal than
69 real hit count). For Z39.50, the information is stored in resultSetStatus
70 member of SearchResponse APDU. For SRU, the information is signalled
71 via SRU diagnostic 59: "Result set created with valid partial results
74 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
78 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
80 Added ZOOM_connection_peek_event.
82 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
83 the following new functions:
84 ZOOM_event_nonblock, ZOOM_connection_process,
85 ZOOM_connection_get_{socket,mask,timeout},
86 ZOOM_connection_fire_event_{timeout,socket}.
87 The existing blocking event handler, ZOOM_event, is a wrapper for the
88 + blocking ZOOM_event_sys_{poll,select}.
90 Implemented function ccl_xml_config which parses XML version of CCL
91 configuration (bug #798).
93 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
95 Added timings utility (yaz/timing.h)
99 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
102 Fixed bug #779: Rotation of apdu.log fails.
104 Fixed for character set conversions:
105 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
106 Honor G1 set in MARC-8 decoding.
108 --- 2.1.42 2006/12/17
110 Fixed bug #775: char conversion does not handle Alternative UTF-8
113 Implemented function yaz_marc_read_line which parses MARC line format
114 records. There is a wealth of formats out there. So far, this function
115 reads line records produced by yaz_marc_write_line.
117 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
118 more generic and easier to remember(!) options: -i format and -o format
119 which specifies input format and output format respectively - where
120 format is one of "marc", "marcxml", "line", "marcxchange".
122 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
123 does not print anything except warnings for records.
125 For yaz-marcdump, added support for MARC split into files (-s) with a given
128 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
129 spec, at http://www.loc.gov/standards/sru/record-update/
130 This has changed the binary layout of the following structs:
131 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
132 bend_update_rr . Patch by Ko van der Sloot.
134 Added GFS utility function bend_assoc_is_alive which returns 1 if
135 association is still alive (client is connected); 0 otherwise (client
136 closed connection). This allows busy servers to stop working for
139 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
140 been a separate piece of software. This version of ziffy has been modified
141 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
143 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
145 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
146 Client code may now interrogate options such as "init_opt_sort" to
147 find out whether the server claims to support various options.
149 --- 2.1.40 2006/11/27
151 Added utilities yaz_{set,get}_esn to set/get element set name from
154 Removed the build of libyazthread.la. The libyaz.so is the threaded version
155 of YAZ and has been so since YAZ 2.1.10.
157 Implemented ZOOM_record_error which returns error information for
158 record (surrogate diagnostic).
160 --- 2.1.38 2006/10/31
162 Updates for SRU Update by Ko van der Sloot:
163 1. Changed name from "operation" to "action"
164 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
165 versions in the code, marked as 'backward compatible'.
166 3. Added diagnostics for SRU Update.
168 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
170 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
172 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
174 For GFS, fixed problem with SRU diagnostic 'First record position out of
175 range' being issued for 0 hits.
177 zoomtst10 part of Windows Build.
179 --- 2.1.36 2006/10/13
181 Implemented yaz_filepath_comp which splits a path into file path
182 components (required by Zebra 2.0.3+).
184 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
185 BSD inspired license until now so this should not have any real impact on
186 anybody. See http://www.opensource.org/licenses/bsd-license.php
188 Fixed bug #687: Missing log lines.
190 Fixed bug #678: CQL to PQF translation does not preserve double-quote
193 Fixed bug #689: SRU diagnostics to be added.
195 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
196 whether a connection is idle (no more work do do).
198 --- 2.1.34 2006/10/04
200 Change type of optval from long to int for invocation of setsockopt with
201 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
203 Added support for specifying the max log file size for the Generic
204 Frontend Server. The size is given with option -r.
206 --- 2.1.32 2006/09/21
208 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
210 --- 2.1.30 2006/09/17
212 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
215 Fixed bug in Generic Frontend Server that could cause a server to stop
216 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
218 For the generic frontend server, the maximum record size is used as maximum
219 size of incoming packages (SRU + Z39.50). The value until was previously
220 only used in Z39.50 Init negotiation and, later, in a session controlled
221 sizes of records returned. This is controlled using -k option. It can be
222 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
224 --- 2.1.28 2006/09/04
226 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
229 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
231 New option for yaz-marcdump -lpos=value which allows setting a portion
232 of MARC header to a certain value.
234 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
236 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
237 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
239 --- 2.1.26 2006/08/15
241 Fixed problem with SRU mode type (soap, get, post) for yaz-client
244 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
246 --- 2.1.24 2006/08/08
248 Fixed MARC ISO2709 encoding routines to deal with character set
251 Minor changes to GFS logging. Database included in search request log
254 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
255 cached/multiple records.
257 Shared libraries are built by default on Unix+configure.
259 Changed cql2pqf transformation to use a different evaluation order. The
260 new order is: always, relation, structure, position, truncation, index
261 and relationModifier. Old order was: always, relation, relationModifier,
262 structure, index, position, truncation. Note that the the latter ones
263 override former ones for identical attributes.. The new scheme means that
264 it is possible to override any existing attribute with a relationModifier.
265 And also that it is possible to override everything for the index rule
266 (except the ones listed in relationModifier). No order is perfect but this
267 one, we believe, covers more real cases.. The "always" should have been
268 called "default", since the attributes there can be overridden with all
271 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
272 compilation phase, but also for yaz-config --cflags output. This allows
273 us to have public headers with Libxml2 stuff in them . It should also,
274 eventually, make Libxml2 checks redundant in packages using YAZ, such
277 --- 2.1.22 2006/06/15
279 Changed SRU update structure bend_update_rr so that SRU diagnostics are
280 stored in uri, message and details.. Previously diagnostics were stored
281 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
282 compatibility.. but he's probably the only one affected, so.
284 Added support for CCL, compiled on the client side, in ZOOM-C. This
285 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
286 input; the resulting query objects can be used for for searching with
287 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
289 YAZ' configure searches for OpenSSL by default.
291 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
292 SL_CTX_use_certificate_file. See
293 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
294 for more info. Thanks to Ko van der Sloot.
296 --- 2.1.20 2006/06/02
298 Bug #600: SRU GET, POST support for yaz-client. Introduced
299 command 'sru' which selects method SOAP/GET/POST.
301 Allow missingValueAction to be specified for the sortspec string -
302 function yaz_sort_spec. By default, the missing value action is null.
303 Use ! to specify "abort". Use = followed by stringvalue to specify default
306 Ensured that Present-handler (if defined) is called in GFS before any call to
307 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
308 searchRetrieve requests.
310 Documentation for YAZ is now based on the Docbook XML/XSLT using
311 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
312 is no longer depending on jade/openjade or docbook-to-man scripts.
313 PDF is no longer part of the distribution - but can optionally be
314 made using DSSSL/jadetex or FOP.
316 Added retrieval handling support in Generic Frontend Server to support
317 conversion between MARC/XML as well as XSLTtransforms. See
318 etc/yazgfs.xml for an example.
320 Added Authentication support to Generic Frontend Server in SRU
321 mode. Authentication using HTTP Basic is supported, as is the use
322 of 'x-username' and 'x-password' parameters in the request itself.
324 Added support for a new character set MARC8s identical to MARC8 except
325 that it converts combined characters to single Unicode characters in the
326 Latin-1 range (when possible).
328 --- 2.1.18 2006/04/24
330 ASN.1 compiler 0.4: generates brief Doxygen file header for
331 generated .h/.c files.
333 Utility yaz_iconv now supports conversion to MARC-8.
335 New facilities for the MARC module. The reading - and writing of
336 content are separate methods for the yaz_marc_t handle. The following
337 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
338 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
339 format). Write functions have prefix yaz_marc_write_.. The existing
340 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
341 available. Removed support for OAI-MARC and simplexml (not the
342 simplexml from PHP5).
344 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
345 to be returned for this connection.
347 --- 2.1.16 2006/03/31
349 Allow multiple languages and charsets to be specified with
350 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
351 negcharset iso-8859-1,utf-8
353 Translation of proximity nodes from CQL into PQF now works.
355 Moved to automake 1.8, 1.9.
357 Added function yaz_log_set_handler which allows a log handler to be
358 installed. This handler will be called for all log messages. Output
359 to file is also produced; but that can be disabled by passing NULL
360 fname to yaz_log_init_file.
362 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
364 For SRW (including GFS), accept application/soap+xml as content-type
367 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
368 produces NO stylesheet reference even if a default stylesheet is specified
371 --- 2.1.14 2006/03/14
373 Updated Windows package to include yazd.dll + yazd.lib for the
374 Development component.
376 If the environment variable YAZ_LOG is set, then it is used as a
377 string indicating the default level of logging to use if not
378 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
379 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
380 used as before. So, for example, to omit warnings from YAZ logging,
383 cql_transform() now map structure and other attributes before indexes,
384 so that index-specific structures and other attributes can override
385 defaults. So now a combination of mapping specifications such as:
387 index.dc.date = 1=date-modified 4=5
388 does the right thing.
390 cql_transform() now also respects the "always" mapping specification,
391 which establishes an initial set of attributes to be used for all
392 terms except where overridden by more specific attributes associated
393 with the index, relation or modifier.
395 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
396 which mode to use; one of "post", "get" or "soap" (SRW, default).
398 Fixes for yaz_iconv routines: changed trie-based character set conversions
399 to use only non-negative values for bit fields due to Sun's C compiler not
400 supporting negative values.
402 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
403 sequences where not read correctly. Fix by Rustam Usmanov.
405 Updated win/makefile to use options, settings which makes things
406 compile with VS C 2005.
408 --- 2.1.12 2006/02/01
410 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
412 In ZOOM socket code, use select instead of poll on MacOSX.
414 ZOOM-C now support client-side compilation of CQL into RPN that is
415 sent to the server, enabling CQL to be used against all Z39.50
416 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
417 ZOOM_query object, and submit it using ZOOM_connection_search().
418 The CQL-to-RPN translation uses a configuration file, the name of
419 which must be specified in the Connection's "cqlfile" option.
421 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
422 function, which takes as its start-term parameter a ZOOM_query object
423 (which may have had either CQL or RPN set into it).
426 --- 2.1.10 2005/11/29
428 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
429 GFS to support this as well. Backend handler, bend_srw_update, does the
430 update work. Code contributed by Ko van der Sloot.
432 Allow retrieval of Search Result-1 information in ZOOM by the use of
433 options that are attached to a result set. ZOOM documentation updated
436 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
437 UTF-8 conversion. Patch by Raj Patel.
439 Added option -m to GFS to control formatting of timestamps in log file.
441 Added 'exit' as synonym for 'quit' in yaz-client
443 Added support for specifying SRW resultSetId + resultSetIdleTime in a
444 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
445 for the new members. Patch by Ko van der Sloot.
447 Added support for SRU POST. It is supported for content-type
448 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
450 Do not build the separate Multi-threaded (MT) library libyazthread.la.
451 Instead make the library libyaz.la multi-threaded. Threading as a whole
452 can still be disabled by configure option --disable-threads. Previosly,
453 with older GLIBCs there were problems with MT libs under Apache. This
454 has now been fixed a long time ago.
456 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
459 CQL module modified to be case insensitive for relations/indexes/operations.
461 Fixed bug in CQL transform code: incorrect value relationModifieder
464 Added 'show all' command for yaz-client which retrieves all results
467 Added new yaz-client, xmles, which takes a (private) OID and
468 a document to be sent as an extended service request.
470 Describe new yaz-client commands wait_response and set_auto_wait.
472 Increase TCP/IP listener backlog from 3 (which I am guessing was
473 copied from the SunOS manual entry way back when) so SOMAXCONN, so
474 that the socket will queue as many incoming connections as it's able
475 to handle ongoing connections. In other words, it will never now
476 refuse a connection that it would be able to handle merely because
477 it's not got around to accepting() enough of the pending connections
478 yet. This is the behaviour anyway under Linux, where the listen()
479 argument is ignored; but not under BSD and on systems such as
480 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
481 YAZ-based servers should now be uniform across operating systems in
484 yaz-marcdump uses 64-bit file access on some systems. This is enabled
485 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
486 This allows yaz-marcdump to read large MARC batches (>2 GB).
488 Modified all YAZ source files - except the source which is auto-generated
489 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
492 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
493 corresponding to the existing *_setl() function. These allow option
494 values containing arbitrary valuues.
496 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
497 ZOOM_resultset_sort() in new applications. Its behaviour is identical
498 except that it returns an indicator of whether or not the sort
499 criterion was accepted (0 for OK, -1 for invalid).
503 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
504 MARC output rather than returning "new" buffer.
506 yaz-client warns about unknown init options.
508 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
512 Added support for SRW sort in Generic Frontend Server. Patch
513 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
514 sortKeys - or NULL if none is provided.
516 Fixed bug #307: It was impossible to specify indefinite/no timeout
517 for ZOOM_event. Special timeout value -1 now means indefinite timeout
520 Added support for multiple languages and charsets to be specified in
521 ZOOM. Each charset/language is separated by a blank. If negotiation is
522 in effect in init-response, Option
523 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
524 Code based on patch by Vasiliy Osadchuk.
526 Fixed bug #306: infinite recursion that occurred when calling
527 yaz_log_level_init as the first call (before other log level or
530 Fixed bug in scan handling in front end server: if preferred-Position-In-
531 Response was non-present, a NULL pointer referece was performed.
535 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
536 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
537 now defined for all those error codes. So instead of putting 109 in
538 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
539 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
541 Modified the yaz-marcdump utility to skip garbage bytes between MARC
544 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
546 Program yaz-client now exits and produces an error message if multiple
547 Z39.50 servers are specified on the command line (none or one allowed
550 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
555 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
557 Fixed bug #272: Preserve spacing for CCL terms.
561 Added support for virtual hosts and multiple backend servers for
562 the YAZ frontend server. The configution is XML based and
563 support specificition of CQL to RPN mappings and explain information.
564 See section "Virtual Hosts" in the YAZ manual.
566 Extended OPAC display utility. OPAC display utility renders
567 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
568 to supplement yaz_marc_decode_wrbuf.
570 Fixed a bug in MARC decoder that could caused it to crash for some
571 invalid MARC records. More diagnostics and warnings where added in
572 XML output (warnings, etc are stored in comments).
574 --- 2.0.34 2005/02/08
576 Fixes for UNIX domain sockets. Bug #261.
578 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
580 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
581 Added yaz_marc_subfield_str which defines subfield lead string which is
582 used in YAZ_MARC_LINE format. Default string is blank+$. Added
583 yaz_marc_endline_str which defines end of fields string used in
584 YAZ_MARC_LINE format. Default string is newline.
586 Experimental support for MarcXChange. This format can be produced
587 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
588 http://www.bs.dk/standards/MarcXchange.xsd
590 Added yaz-client commands scansize that sets maximum number of
591 entries to be returned by scan.
593 --- 2.0.32 2005/01/11
595 Added support for SRW scan in yaz-client and Generic Frontend Server.
597 * Added whereInList member to SRW Scan Term.
599 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
601 Fixed NMEM system to return aligned blocks on the smallest boundaries
602 that are suitably aligned for all possible types on the particular
603 architecture YAZ is being built for.
605 --- 2.0.30 2005/01/04
607 Fixed numerious warnings that was issued with newer versions of GCC.
609 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
610 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
613 Make YAZ Generic Frontend Server slightly faster.
615 Enhance (and reduce) logging for Generic Frontend Server.
617 Revert YAZ log system so that it flushes every write operation
618 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
620 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
621 instead of LOG_, due to name clash with syslog(3). LOG_ are still
622 present. New applications should define YAZ_USE_NEW_LOG=1 - this
623 will effectively disable old definitions.
625 --- 2.0.28 2004/11/09
627 Added yaz_log_time_format which specifies log format using
630 Added yaz_log_module_level which returns mask for a module. Value
631 is non-zero mask a if module is enabled; zero if disabled.
633 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
634 in include/yaz/cql.h.
636 Fixed bug #176: Dont throw diagnostics on empty SRU args.
638 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
640 Fixed bug #172: RPM builds does not enable SSL.
642 Doxyfile.in part of dist. Doxyfile generated by configure.
644 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
645 are given and the corresponding component does not exist.
647 Extend CCL documentation in YAZ reference. Describe r=r.
649 --- 2.0.26 2004/10/01
651 Fixed MARC->MARCXML conversion to properly deal with
652 fields, subfields, indicators having non-ASCII characters.
654 Fixed MARC->MARCXML conversion so that ASCII control characters
655 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
658 Added YAZ GFS support for conversion from Z39.50 surrogate
659 diagnostics to SRW surrogate diagnostics.
661 Bug fix: YAZ GFS did not return schema in explainResponse.
663 --- 2.0.25 2004/09/30
665 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
666 now converts recordSchema to elementSetName as well as schema URI.
668 Fixed bug in COMSTACK that prevented HTTP request packages from being
671 --- 2.0.24 2004/09/29
673 Added CCL facility r=r "range" which is similar to r=o "ordered" but
674 does not require white-space before and after the dash in a range, e.g.
675 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
678 Fixed a few AC_TRY_LINK configure tests that did not operate properly
679 due to new GCC removing "redundant" code.
681 Added yaz-client commands scanpos and scanstep that sets preferred
682 position and step-size for scan.
684 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
686 Added CCL utility ccl_qual_buf which parses one or more CCL
687 spec lines in a buffer.
689 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
690 of name and value - ignoring empty lines and comments.
692 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
694 Added odr_get_element_path which returns current element path for an
695 ODR handle. This utility is useful in error handling or user-defined
698 Added ODR_PRINT utility odr_set_stream which is is a more generic
699 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
700 to a write function and pointer to close function. The close function - if
701 non-NULL - will be called during odr_destroy.
703 Fixed bug in CCL parser where truncation char was not removed from
704 right side when truncation=both was in effect.
706 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
709 --- 2.0.23 2004/08/11
711 Fix buffer overrun in CQL parser when dealing with proximity (%).
713 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
714 to UTF-8/UCS conversion is now only based on codetables.xml.
716 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
718 --- 2.0.22 2004/08/06
720 Add support for more "commit changes" in ZOOM (uses Extended Services).
722 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
725 Yet another small fix for configure of SSL.
727 --- 2.0.21 2004/05/14
729 Fix SSL libs for configure when --with-openssl=DIR is given.
731 --- 2.0.20 2004/05/10
733 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
735 SSL comstack now uses yaz.pem certificate file on server side
736 by default. Certificate filename can be configured by calling
737 comstack function cs_set_ssl_certificate_file before cs_bind is used.
739 Fix bug regarding multiple calls to ZOOM_connection_connect.
741 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
743 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
744 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
746 ZOOM now allows inspection of X509 peer certificate for verification.
747 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
749 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
750 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
751 as "modular" but it simplifies things.
753 Added cs_get_peer_certificate to that returns peer X509 PEM.
755 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
756 NULL if SSL is unavailable.
758 Documentation about MARC decoding tools.
760 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
762 --- 2.0.19 2004/03/30
764 Rename CHANGELOG to NEWS to follow GNU style packing.
766 Fix bug with missing initialization of member in init_diagnostics.
767 This bug affects threaded version of GFS server.
769 --- 2.0.18 2004/03/20
771 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
774 Ensure zlib.dll is packed with Windows install.
776 --- 2.0.17 2004/03/17
778 Fix encoding of xsd:string to use text instead of CDATA.
780 Fix endless loop in CQL parser with unbalanced ".
782 Use a more compact way to store MARC-8 conversion tables.
784 --- 2.0.16 2004/03/16 Debian only
786 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
789 Update CQL parser to use new CQL 1.1 modifiers for booleans and
794 --- 2.0.15 2004/03/01
796 Another fix for decoding of XML packed records.
798 --- 2.0.14 2004/02/25
800 Fixes for Chunked encoding. White space not ignored after length spec.
802 Update NS and use default NS for SRW diagnostic elements.
804 --- 2.0.13 2004/02/23
806 Implement ZOOM_resultset_cache_reset which resets record cache.
808 Implement ZOOM_resultset_sort which sorts a result set.
810 Implement chunked HTTP transfer.
812 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
814 --- 2.0.12 2004/02/16
816 Added member 'schema' to bend_explain_rr structure so that backend
817 can specify explain record identifier. Defaults to Zeerex 2.0.
819 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
821 --- 2.0.11 2004/02/16
823 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
826 Added init command for yaz-client which sends "extra" init request.
828 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
829 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
831 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
833 Make ZOOM error code for "invalid query".
835 Fixed compilation for SSL which wasn't properly enabled for all platforms.
837 --- 2.0.10 2004/02/05
839 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
842 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
844 Added option -p <file> to make Generic Frontend Server to write PID file.
846 Added option -D to put Generic Frontend Server in background on its own.
848 Make ZOOM C recognize option "password". If unset, "pass" is used
849 (for backwards compatibility).
851 Fixed a bug in Generic Frontend Server that could make it crash if a
852 client sets characterSetNegotation bit, but didn't pass negotiation stuff
855 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
856 Must be issued before open, in order to be in effect.
858 --- 2.0.9-6 2004/01/12 Debian/Windows
860 Make the SRU server more picky WRT unknown params, etc.
862 Bug fix: ZOOM scan response didn't return displayTerm - when present.
864 New YAZ client command, options, that sets Z39.50 options.
866 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
867 options from a string of tokens (one token for each option bit).
869 Update SRW diagnostic code messages.
871 --- 2.0.9-5 2004/01/07 Debian/Windows
873 Handle user defined stylesheet for SRW/SRU.
875 --- 2.0.9-4 2004/01/06 Debian/Windows
877 Fix bug in decoding of Content-Length.
879 --- 2.0.9-3 2004/01/06 Debian/Windows
881 Fix a bug with decoding of XML packed records.
883 --- 2.0.9-2 2004/01/05 Debian only
885 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
887 Fix bug in SRW/SRU diagnostics decoding.
891 Fixed bug in Generic Frontend Server which could drop records exceeding
892 preferred message size. Reported and fixed by Irina Dijour.
894 Fixed calculation of package size for structured records in Generic
895 Frontend Server. Reported and fixed by Irina Dijour.
897 Fixed namespace for SRW/SRU diagnostics.
899 Fixed SEGV in yaz-client that occured for HTTP connection errors.
903 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
904 this version is incompatible with version 1.0 and older YAZ SRW/SRU
907 CQL changes to reflect recent changes to the specification:
908 * Documentation talks about context sets instead of index sets.
909 * Documentation talks about indexes instead of qualifiers.
910 * The CQL-to-PQF transformer's configuration file now uses
911 "index.set.name = <attributes>" instead of the old form
912 "qualifier.set.name = <attributes>". (Both forms are still
913 understood but the latter is deprecated.)
914 * CQL terms with no explicit index specified are now interpreted as
915 cql.serverChoice instead of srw.serverChoice (which of course
916 behaves exactly the same.)
920 MARC conversion can now generate ISO2709 output in another
921 character set. yaz-marcdump uses this facility if you invoke it
924 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
925 functions from there can be used from C++.
929 Frontend server now transfers memory from decoded packages to stream
932 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
933 references to show up.
935 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
936 the ZOOM Abstract API. The older names for the same options are still
937 also supported for the benefit of old applications.
939 ZOOM-C supports "implementationId" and "implementationVersion" options
940 to go along with "implementationName". These allow the user code to
941 specify identification strings to be sent to servers.
942 Add OID for the new ExtLite attribute set.
944 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
945 as requested/supplid by Ere Maijala <ere@atp.fi>
947 For generic frontend server, reverse the order of
948 "toolkit-supplied / application-supplied" strings sent as implementationId,
949 Name and Version. Also, remove the spaces around the slash. This brings
950 the GFS in line with the behaviour of ZOOM-C on the client side.
952 Add function ZOOM_scanset_display_term.
954 yaz-client shows scan displayTerm if present.
956 Utility yaz-iconv is now installed by default along with the man page
959 Extend configure check for OpenSSL to use pkg-config where available (such
962 Incorporate patch by Morten Bogeskov which allows a Unix file socket
963 server to specify uid/gid/mask for socket using the format
964 unix:[user=uid,][group=gid,][umask=mask,]file=path
965 If file= is omitted the existing format is assumed, e.g.
967 in which case the mask is 0666 (rw for everybody).
969 Major restructure of YAZ source. All source in libyaz is in src directory.
970 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
971 util (utility programs such as ASN.1 compiler, yaz-marcdump).
973 Added man page for utility yaz-marcdump (used to be called marcdump).
974 yaz-marcdump is installed by 'make install'.
976 Fixed a memory leak in Generic Frontend Server that occurred when decoding
977 of incoming package failed.
979 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
981 Change prototype of odr_perror: add const to message string.
983 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
985 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
986 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
987 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
988 DNS lookup. There should not be any compatibility problems with this
989 assuming that blocking=1 or 0 is used.
991 Fix bad reference in UNIX comstack in function cs_addrstr.
993 Fix for compilation on AIX.
995 The generic front-end server (server/seshigh.c) now supports returning
996 Init diagnostics to the client in User-information-field, in
997 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1000 --- 2.0.4 2003/09/04
1002 Allow any CQL relation (not just all,any,exact,scr).
1004 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1005 that features the same UI.
1007 Implemented command update0 in YAZ client which is equivalent to
1008 update but uses old of Ext Update ASN.1.
1010 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1011 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1012 Previously no OID was used for this info.
1014 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1015 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1016 returns 'malformed search term' otherwise.
1018 SortResponse member resultCount now set to NULL in sort handler of
1021 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1024 Add three new utility functions for translating OIDs between various
1025 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1026 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1027 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1028 char *oid_to_dotstring(const int *oid, char *oidbuf);
1029 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1031 Reverted modifications for ES Update definition for z_IU0Update
1032 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1033 is back to YAZ 2.0.2.
1035 String value attributes for CCL parser.
1037 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1038 which their FirstSearch server returns in Init responses, sometimes
1039 carrying useful diagnostic information when Init fails. This has the
1040 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1041 "z39.50/oclcui.asn", where its definition is somewhat different from
1042 what OCLC document on their web-site, as required to interoperate with
1045 Support for anonymous authentication in yaz-client. Use the command
1048 * Fix the OID of the Index Data-local "admin" Extended Service from
1049 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1050 the 1000, which indicates a locally-defined OID, was a mistake.
1052 --- 2.0.3 2003/06/20
1054 Fix CCL directive @case handling so that it affects string match for
1055 both CCL keywords and qualifiers.
1057 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1058 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1059 Decoder has been updated with ASN.1 changes as listed in
1060 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1061 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1062 z_IUUpdate, remains unchanged.
1064 ZOOM_record_get may now return a record in a specific character set.
1065 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1066 "from" is the character set of record as returned by target. "to" is
1067 the character set to be returned. If omitted, "to" is UTF-8.
1069 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1071 New ODR utility, odr_getelement, which returns name of element for
1072 which encoding/decoding failed.
1074 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1075 in cases where a required element was omitted.
1077 Bug fix: some MARC8 sequences were not converted.
1079 New ZOOM option "step" which specifies number of records to be
1080 retrieved in one chunk. Used in conjunction with "start" and "count".
1082 SRW support for yaz-client. Use scheme http: to use it, e.g.
1085 yaz-client no longer does (un)intelligent character set conversions
1086 by default. Can be enabled with charset and marc_charset commands.
1088 xmalloc trace fix for 64-bit systems such as DEC alpha.
1090 Solaris 2.6 compile fix.
1092 New function, cql_strerror() translates SRW error codes, as returned
1093 by cql_transform_error(), into human-readable English strings. Used
1094 in yaz-client diagnostics when appropriate.
1096 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1097 converts it into a type-1 query which is sent to the server. This
1098 makes CQL available for use with all Z-servers, as opposed to the tiny
1099 minority that can handle CQL queries themselves.
1101 --- 2.0.2 2003/04/28
1103 New Debian package layout similar to the Redhat Package layout.
1105 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1106 and search result respectively.
1108 --- 2.0.1 2003/04/25
1110 Redhat package is now several packages: libyaz (runtime libraries),
1111 libyaz-devel (development and documentation, and yaz (utility programs).
1112 Package spec file by Morten Bøgeskov.
1114 New member 'schema' in struct bend_fetch_rr which the name of requested
1115 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1116 handler MAY set this to reflect the schema of the returned record.
1118 New member 'display_term' in struct scan_entry. GFS now sets member entries
1119 and allocates scan entries to be filled by user scan handler. In previous
1120 version, entries member was allocated by the scan handler. That still works,
1121 but the GFS will ignore member display_term - assuming it was NOT set by
1122 the handler. The fact that the GFS now allocates the entries both allows
1123 for new members and makes a scan handler easier to write.
1125 Fix CQL lex buffer overflow.
1127 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1128 SRU default recordPacking is string.
1130 SRU protocol support for frontend server.
1132 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1134 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1136 Added scan for the ZOOM shell (zoomsh).
1140 * String Identifers for Schemas (Amendment 5).
1141 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1142 Old definition for schema
1143 Odr_oid *schema; /* OPT */
1148 Z_InternationalString *uri;
1149 #define Z_Schema_oid 1
1150 #define Z_Schema_uri 2
1153 * resultCount parameter to Sort Response (Amendment 1).
1154 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1156 Support for SRW 1.0 over HTTP. This is an optional feature and
1157 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1160 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1161 on the same port. SRW SearchRetrieveRequests are mapped
1162 to bend_init,bend_search,bend_fetch,bend_close.
1164 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1166 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1167 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1169 ZOOM connections are SRW based if schem http is used for hostname
1170 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1171 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1173 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1174 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1175 distance=n, order=true/false, relation=le, prox unit=word. If
1176 n is omitted, distance 1 is used.
1178 Fixed problem with C compiler include path in wrong order.
1180 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1181 on Solaris. Patch from Ko van der Sloot.
1183 New MARC decode API. All new functions operate on a yaz_marc_t
1184 handle. The most important new functions are: yaz_marc_create,
1185 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1186 decode and destroy respectively. Decoder can produce formats
1187 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1188 include/yaz/marcdisp.h.
1190 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1191 to UTF-8, UCS-32, wchar_t or Latin-1.
1193 * Prototypes for yaz_iconv_-functions moved to separate header
1194 include/yaz/yaz-iconv.h.
1196 Make a few private functions 'static' in unix.c. This prevents
1197 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1199 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1200 are set when Init Response is received.
1202 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1203 but returns diagnostic set as well.
1205 New function yaz_strerror which is a portable wrapper for
1206 strerror/strerror_r/GetLastMessage.
1208 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1209 is returned for MARC. If type is "oai", then OAI MARC is returned.
1211 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1214 --- 1.9.2 2002/11/26
1216 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1218 Fix bad race conditions on SIGTERM and terminate gracefully in
1221 Move retrieval (data1) module to Zebra since nobody seems to be
1224 Add GRS-1 render for ZOOM using same format as yaz-client.
1226 --- 1.9.1 2002/10/05
1228 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1230 Fix broken ESpec handling in data1 module.
1232 SGML reader parses comments and makes them part of the data1 tree.
1234 Added several type casts so that YAZ compiles as C++ code.
1236 ZOOM didn't handle PDU encoding failures properly.
1238 Added more Bib-1 diagnostics (approved extensions).
1240 GNU configure: better check for iconv.
1242 More portable use of accept, getpeername. Check for socklen_t. Use
1243 int/size_t if socklen_t is not defined.
1247 PQF parser rejects bad queries - including those with extra
1248 characters in them. PQF parser used to silently ignore that.
1249 Cleaner API for PQF added, which allows you to get detailed
1250 error information for bad queries (see yaz/pquery.h).
1252 Fixed bug in ZOOM_record_get for type "database".
1254 Implemented mini iconv library supporting conversions between
1255 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1257 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1259 --- 1.8.9 2002/08/20
1261 Fixed ZOOM C record cache so that preferredRecordSyntax and
1262 elementSetName is used to check for already fetched records.
1264 --- 1.8.8 2002/08/02
1266 Added three members in bend_initrequest structure to facilitate
1267 character set negotiation.
1269 Fixed a bug in frontend server that could cause indefinite
1270 loops under rare conditions.
1272 Revised character set utilities (charneg.h) so that encoding
1273 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1275 For PQF, directive @term <type> sets term type for Scan/Search.
1276 Here <type> is general, string, numeric, null. The term type
1277 is inherited - just like @attr.
1279 New call odr_set_charset that sets character set conversion for
1280 international-strings on a ODR stream. Prototype is:
1281 int odr_set_charset(ODR o, const char *to, const char *from);
1282 The InternationalString is still represented as C string in YAZ
1283 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1284 won't). On the protocol level, you can use any encoding.
1286 Support for UNIX sockets in ZOOM.
1288 Solaris recv sometimes returns errno == ENOENT. It is treated as
1289 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1291 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1292 both client and server. Code by Morten Bøgeskov.
1294 --- 1.8.7 2002/05/22
1296 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1297 that they can be used directly from Visual Basic. You must recompile
1298 your windows APP if you're using ZOOM.
1300 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1301 Commands "lang" and "charset" sets language and character set respectively.
1302 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1303 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1305 Attributes from multiple CCL fields may be OR'ed rather than merged
1306 using directive "@field or". Fields are still merged by default -
1307 equivalent to "@field merge".
1309 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1312 Fixed bug in zget for parameter ExtendedServicesResponse.
1316 --- 1.8.6 2002/03/25
1318 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1320 Client displays USR.1:SearchResult-1 (hits per term).
1322 Additional Search Info for search in Generic Frontend Server.
1324 Fixed CCL parsing of "field=s".
1326 WIN32 installer - using the excellent NSIS software from nullsoft.
1328 Fixed CCL parsing of "field = - <number>".
1330 Added function yaz_marc_decode that decodes MARC for line mode
1331 display or XML (similar to that used by JZKit).
1333 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1334 Z39.50. But ISO/ILL was, however.
1336 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1337 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1339 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1340 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1342 --- 1.8.5 2002/02/03
1344 New YAZ client features: Command completion and new commands:
1345 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1346 Code provided by Jacob Poulsen.
1348 New call oid_trav, that visits all registered OIDs via callback.
1350 Function ZOOM_record_get now returns const char pointer rather than
1351 void pointer. It saves a lot of type casts.
1353 For YAZ client, command "auth" now allows you to set authentication
1354 in IdPass style. It is enabled when three tokens are given - order
1355 is user, group and password.
1357 Fix memory leaks in MARC record handling for ZOOM.
1359 New option for YAZ client, -k <kilobytes> that sets
1360 maximum record size. Similar to -k option for generic frontend
1361 server and yaz-ztest.
1363 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1365 Prefix query parser reports "fail" when bad attribute set is given.
1367 Fix in MARC decoder. Proximity logging. Fix for attribute set
1368 in scan handler for server. Patches by Shigeru Ishida.
1370 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1373 Configure option --with-openssl=<dir> now works when a directory is
1374 specified. Patch provided by Morten Bøgeskov.
1376 New option for YAZ client, -u <auth>, that sets authentication.
1378 ZOOM fix: error information was sometimes "missing", since error
1379 was cleared/reset too when it shouldn't.
1381 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1383 --- 1.8.4 2002/01/04
1385 Scan for ZOOM API. New object ZOOM_scanset. New functions
1386 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1387 ZOOM_scanset_destroy.
1389 New ZOOM function, ZOOM_connection_last_event, that returns type
1390 of last event (such as "receive data", "send data", "apdu received",
1393 New ZOOM option, schema, that specifies schema for retrieval.
1395 New CCL feature. Qualifiers can be aliases for one or more
1396 other qualifiers (if more than one is given, OR is used).
1398 ZOOM uses named result sets if target supports it.
1400 Two new YAZ client commands: . (dot, which sources a script of YAZ
1401 client commands), and ! (to execute shell command.). Implemented
1404 Working on Debian packages.
1406 --- 1.8.3 2001/11/19
1408 YAZ client enables named result sets only if target supports it.
1410 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1412 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1413 with key="host" to get same result.
1415 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1416 Function Z3950_resultset_record(s) returns references to records
1417 "owned" by resultset. To become owner use Z3950_record_clone.
1419 Function z_ext_record handles Extended Services. Thanks to
1422 --- 1.8.2 2001/11/12
1424 CCL Parser fix: ignore token comma when dealing with and-lists.
1426 Documentation updates for COMSTACK.
1428 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1429 Changed prototype Z3950_records. For some functions, int parameters
1430 were changed to size_t.
1432 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1435 New MARC decode/display function, marc_display_exl, which properly rejects
1436 non-ISO2709 records. YAZ client uses it.
1438 --- 1.8.1 2001/10/29
1440 Fix bug: local attribute set wasn't set correctly in PQF strings.
1444 * Old Z39.50 codecs no longer supported.
1446 Added ZOOM C binding. See http://zoom.z3950.org/
1448 Renamed states for COMSTACKs to avoid confusion with events.
1450 Implemented cs_look and proper cs_rcvconnect.
1452 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1454 Configure detects POSIX threads on OpenBSD.
1456 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1457 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1459 When error is returned from present handler, non-surrogate diagnostic
1460 is returned in present response (and fetch handler is no longer called).
1462 * Minor adjustments to pquery parser (PQF). Token characters may be
1463 escaped by using backslash (C-style).
1465 PQF parser allows string attribute values to be specified. For @attr,
1466 non-numeric characters after the equal-sign are treated as strings
1467 (e.g. @attr 9=title).
1469 CCL trunction character may be defined (@truncation in file)
1471 * function zget_ExtendedServicesRequest sets waitAction to
1472 waitIfPossible (was wait).
1474 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1477 CCL operator names may be set in field definition files (CCL_bibset).
1478 See ccl/bib1 for an example.
1480 Fixes in ASN.1 compiler for C++ compatibility.
1482 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1483 and "op_or" to avoid conflict with C++.
1485 Fixed problem with GNU readline detection on Redhat 7.0.
1487 Added step-size for Scan backend handler.
1489 Fixed bug that made the frontend server crash when no attribute
1490 set was specified for scan.
1492 Front-end server automatically switches to original working directory
1493 when installed as an NT service. Previously -w had to be specified to
1496 Added extended attributes for retrieval module (data1), so that data1
1497 records carry d1_readXML/SGML attributes. d1_read also supports
1498 null-data rules ( <tag/>)
1500 On UNIX when POSIX threads are available, a separate library libyazthread
1501 is created. Programmers should link with that library and the yaz library
1502 when using threads. The reason for the split was that some applications
1503 on Linux, such as Apache, doesn't work well when using shared objects that
1506 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1507 (or any frontend server) in SSL mode by specifying ssl: followed by
1508 address. Only tested on UNIX.
1510 Added feature for CCL module. Virtual structure s=al or s=ol generates
1511 and-list and or-list respectively instead of phrase search.
1515 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1516 log_mask_str. This was done to avoid name conflicts with other libraries
1517 (such as other PHP extensions).
1519 Added raw OID member for preferred record syntax (request_format_raw)
1520 and returned record syntax (output_format_raw) for backend fetch method.
1522 Config file yaz-config now accepts options so that it returns specific
1523 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1525 Shared library support for UNIX using GNU libtool.
1527 * Modified backend interface. Request/Response struct's replaced by
1528 one read/write C struct. For example bend_fetchrequest and
1529 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1530 Every handler - even search has to be registered in bend_init
1531 handler. This means that the YAZ library no longer refers to
1532 external functions and it makes it possible to make the whole
1533 thing a single DLL/SO.
1535 Added Segment handler for backend server.
1537 Added Zmbol/Zebra administrative functions to YAZ client.
1539 Threaded frontend server on UNIX (when POSIX Threads are available).
1540 Starting the server with option -T enables multi-threading.
1544 Added configure option --enable-comp/disable-comp to control use
1545 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1546 located in sub directory asn.
1548 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1549 in ${exec_prefix}/bin along with the other programs yaz-client and
1552 GNU automake used to maintain makefiles.
1554 Added several OID's.
1556 Changed retrieval module so that we can load records with no abstract
1557 syntax defined. Tagpaths in these records are fully composed of string
1560 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1564 On UNIX, the generated makefile now supports a proper 'make install'.
1565 The prefix can be set via GNU configure to set the install location
1566 (default is /usr/local).
1568 * YAZ programs client and ztest were renamed to yaz-client and
1569 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1570 locations, such as /usr/bin,/usr/local/bin,etc.
1572 * YAZ Header files were moved from include to include/yaz. YAZ Header
1573 files are referred to as include <yaz/log.h> rather than <log.h>.
1574 The YAZ include path (-I ..) is therefore the same as before. Programmers
1575 should update their #include statements or use -Ipath/include/yaz
1576 instead. The main motivation for doing this change is that YAZ header files
1577 can be installed in "standard" locations /usr/include,/usr/local/include
1578 without introducing conflicts, since ALL YAZ header files are stored
1579 in subdirectory yaz (under /usr/include for example).
1581 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1582 rather than project/workspace files. We switched because project files
1583 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1586 Changed name of logging function, logf, to yaz_log, to prevent name
1587 clash with some math-log functions. The YAZ header log.h defines logf
1588 to yaz_log (#define) so there should be no incompatibilities by this
1591 Added bend_start/bend_stop handlers for server. These handler are
1592 called on start/stop of server. For windows they are called whenever
1593 a service is started/stopped.
1595 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1596 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1597 in util/yc.tcl. The auto-generated C code structures are, in a few
1598 cases, incompatible with the old decoders. There are differences in the
1599 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1600 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1601 The preprocessor variable ASN_COMPILED is defined when the compiled
1602 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1603 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1604 wish to use the old encoders/decoders you can specify --disable-yc
1607 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1608 version so that it supports both new - and old version of DB Update
1610 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1611 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1612 change. The name parameter can be set to 0 in which no name is specified
1613 for the construction. The macros odr_implicit and odr_explicit sets name
1614 parameter to zero for the construction involved. New macros
1615 odr_implicit_tag and odr_explicit_tag are similar to the others,
1616 except that a name parameter is added. For programmers' that don't use
1617 ODR they probably only need to change the call to z_APDU and z_External.
1619 Added access control facility by interfacing the TCP wrapper library.
1620 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1621 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1622 name of the daemon and enables the access control as specified in
1623 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1625 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1626 den Dool <H.M.vdnDool@kub.nl>.
1628 Added reference ID parameter to most functions in server API - refer
1629 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1631 Changed name of ccl library to libccl.a (was ccl.a).
1633 Fixed bug in decoder for Explain (Category TargetInfo).
1635 Added support for GNU readline in client. Thanks to Jacob Poulsen
1636 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1638 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1639 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1640 IMPLEMENTATION! This change was made to the development version before
1641 the ZIG decided to retract the amendment. If any users MUST be
1642 compatible with the original Update definition, PLEASE CONTACT US, and
1643 we will include a separate definition corresponding to the old Update
1644 ES. Note that because of the change to the ASN.1 of the
1645 TaskPackageRecordStructure we cannot define a single structure that
1646 will support both versions.
1648 * Added const modifier to buffer parameter for some ODR/BER encoding
1649 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1650 completeWAIS, odr_dumpBER.
1652 Fixed bug in client.c which caused a crash when a scanResponse didn't
1653 contain positionOfTerm.
1655 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1656 * will cause an error in a client if a non-YAZ target sends both a
1657 * list of Scan entries and non-surrogate diagnostics.
1659 Retrieval module enhancements. Tag sets may be typed in the reference
1660 to it. From the .abs-file the "tagset" directive takes a third optional
1661 integer type for the tag set referenced. From a .tag-file the "include"
1662 directive takes a third optional type as well. The old "type" directive
1663 in the tag set itself is still recognized but acts as the default type
1666 Backend interface change. Individual Scan terms returned from bend_scan
1667 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1668 in include/backend.h.
1670 Retrieval module enhancements. Multiple tag sets and attribute sets may
1671 be specified in abstract syntax specs. Revised the error/warning for
1672 logging messages reported by the retrieval module when reading the
1675 Object Identifier system (oid_..) changed. The API is backwards
1676 compatible but the oid-routines now allocates new OID's when needed.
1677 Raw OID's may be specified in oid_getvalbyname.
1679 YAZ now uses GNU configure to generate Makefile(s).
1681 * Minor changes in some of the member names of DeleteResultSetRequest and
1682 DeleteResultSetResponse. See include/proto.h.
1684 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1685 and added member 'languages' in TargetInfo (which was missing).
1687 Changed the way attribute sets are handled in the retrieval
1688 module. These are now cached, just like the abstract syntaxes
1691 Changed YAZ so that it links with compiled ASN.1.
1693 Added Explain-schema definitions and mapping routines. The following
1694 Explain categories have been implemented: AttributeDetails,
1695 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1697 Fixed minor bug in Windows version of Server Library.
1699 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1701 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1703 Added EXTERNAL: UNIverse Resource Report (non-standard).
1705 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1706 ENUMERATED and SET OF.
1708 * Added 'const' to some of the char pointer arguments for the
1709 functions, data1_read_node, data1_getelementbytagname,
1710 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1713 Fixed bug in data1_insert_taggeddata - the last_child member of
1714 parent wasn't initialised.
1716 * Changed data1_read_record and data1_read_node so that the supplied
1717 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1718 doesn't refer to any parts of the "SGML"-buffer.
1720 Fixed bug in server library (Windows version of statserv_remove).
1722 * Changed code so that it compiles as C++. The type definition
1723 of Odr_fun which is a member of Odr_arm was changed. The result is,
1724 that an explicit typecast is needed for the fun pointer when
1725 using Odr_arm - as in:
1726 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1728 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1730 Implemented the new structured date and time definition as approved
1731 by the ZIG. Added schemaId element to the specificTag in Espec-1
1732 (also approved at the last ZIG). Thanks to RVDM.
1734 Added some Object identifiers (RVDM).
1736 Changed the Update Extended Service (RVDM).
1738 Added command "refid" to client which specifies referenceId for
1739 the following requests.
1741 Implemented extended service handling for server. See ztest.c
1742 for an example as well as backend.h. New handlers are registerd
1743 in the Init handler.
1745 * Changed interface for sort in server.
1747 Added new members to statserv_options_block. It allows a server
1748 to read options from another source than just the command line. Thanks
1749 to Charles Woodfield.
1751 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1752 renamed to zboolean. Some C++ compilers complained about the name.
1754 Minor changes to gils.abs. Added index 's' (sort) on title
1755 and date/time-last-modified.
1757 --- 1.4pl2 1998/1/30
1759 Fixed bug in server library regarding inetd mode (-i). This bug
1760 was introduced by release 1.4.
1762 --- 1.4pl1 1998/1/29
1764 Added sort facility in client and backend server interface.
1766 Fixed problem with dependencies in Makefile(s).
1768 Fixed bugs for encoders/decoders of extended services and
1771 Implemented sub-tree feature for schemas. Sub-trees are
1772 referenced in *.abs-files. See explain.abs for an example
1773 of the use of this feature.
1775 Modified bib1.att; local attributes for ANY didn't include
1776 ANY itself (only affects use of the retrieval module).
1778 Fixed bug in plain SGML reader in function data1_read_node:
1779 tags with prefix "var" was incorrectly interpreted as variants.
1781 Added feature "sub-schemas" to enable references to - and definitions
1782 of - group of elements.
1784 * Removed member parent from type data1_element (in data1.h).
1786 Implemented function odr_nullval() that returns the value of
1789 * Removed member num_children from data1_node (in data1.h).
1791 Made NT service interface part of the server library. The
1792 function statserv_main uses the NT service when required and
1793 calls the statserv_start / statserv_close routines.
1795 Routine zget_SearchRequest and zget_PresentRequest fills
1796 resultSetName/Id member with "default" instead of "Default".
1798 Fixed memory leak in server. Request queue member wasn't freed.
1800 Fixed nmem_exit so that memory is freed.
1804 Revised the CCL parser utility to be thread safe.
1806 Added function, oid_ent_to_oid, to replace the function
1807 oid_getoidbyent, which is not thread safe.
1809 * Added nmem_init and nmem_exit to initialize and release
1810 NMEM resources. Function nmem_init should be called once in the
1811 initial thread before NMEM/ODR is used. statserv.c and client.c
1812 have been changed accordingly. The change was necessary to make
1813 NMEM thread safe. The NMEM memory pool is shared amongst threads
1814 in a process. Unix-based applications will still work fine without
1817 Added NT Services interface for the the Z39.50 (statserv) Server.
1818 Refer to the ztest.c source on the usage.
1820 Windows 95/NT port using MSVC5.0. Project files are included in the
1823 * Defined new 'global' handle for the retrieval (data1) system. The
1824 new handled, data1_handle, describes the state of the data1 system.
1825 This handle is passed as first argument to virtually all
1826 data1 related routines. The functions data1_create and data1_destroy
1827 creates and destroys a data1 handle respectively.
1829 Added ODR encode stream member to all backend request structures
1830 init, search, scan etc. This stream should be used to allocate all
1831 memory used for the response when thread safe operation is needed.
1833 Changed the comstack utility, cs_addstr, to be thread safe. The
1834 returned hostname string returned by the function is now part the
1837 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1838 function. The cs_straddr takes a COMSTACK handle as argument, so this
1839 function must be used after cs_create and before bind/connect.
1840 This function is thread safe.
1842 Moved test server to 'ztest' directory - generic server code still
1843 in 'server' directory.
1845 Made prefix query (pquery.c) utility thread safe.
1847 Added new function modifier YAZ_EXPORT to 'export' public DLL
1848 functions when using windows (see include/yconfig.h).
1850 Added definitions to the OID database (util/oid.c) (RVDM).
1852 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1854 Added call to ccl_rpn_delete in client program.
1856 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1857 release of RPN structure.
1859 Added support for C++, headers uses extern "C" for public definitions.
1860 With input from RVDM.
1862 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1863 Thanks to Ronald van der Meer (RVDM).
1865 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.

1872 Fixed null-reference problem in GRS-1 output filter.
1874 Proximity operator added to Prefix Query Format (PQF).
1876 In test client command "base" accepts multiple databases.
1878 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1882 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1884 Smallish bug-fixes in the new encoders/decoders (explain).

1901 --- 1.2 1996/6/10 (1st anniversary release)
1903 Added Summary record syntax. Lightly tested.
1905 Added OPAC record syntax. Untested.
1907 Added ResourceReport service encoders/decoders. Untested.
1909 Fixed bug in z_Unit - wrong tagging on unitSystem.
1911 Fixed bug in the DiagRecs decoder.
1913 Added options for max PDU size and session timeout to frontend-server.
1915 Added documentation of query-language parsers and other supporting utilities.
1917 [frontend-server] Added Attribute set to the bend_scanrequest API.
1919 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1920 surrogate diagnostics were generated.
1922 [retrieval] Allow multiple local values for attribute.
1924 [retrieval] Allow multiple attributes per element in .abs files. index type.
1926 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1928 --- 1.1pl2 1996/4/10
1930 Minor changes, mostly specific to Zebra's requirements (retrieval)
1934 Repaired bug in frontend server when running multiple listening
1935 endpoints in dynamic mode.
1937 z_External() now won't break if a known, ASN.1 value comes encapsulated
1938 in an octet-string. The value will pass through unmodified in an Odr_oct.
1940 Added a bit of code to the demo client to decode & display
1941 ASN.1-structured records represented in the octet-aligned branch of
1942 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1944 Added z_ext_getentbyref() to the ASN module. Doc updated.
1946 * Completed the SCAN definition in the ASN module. This may break SCAN
1947 code based on older YAZ-versions at compile-time. The fix is easy -
1950 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1951 under the SCAN definition. Remember to initialize this, server-people.
1953 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1954 that this does not extend to ODR and ASN.
1956 Comstack allows insertion of established socket (primarily for
1957 inetd-operation of servers). Doc updated.
1959 Front-end server can now start from the inetd in TCP mode. Doc
1962 --- 1.0pl4 1996/1/24
1966 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1967 the rank and record number.
1969 Adjustments to the frontend server.
1971 Fixed diagnostic BER dumper. It ignored the file argument.
1975 Various changes to retrieval module.
1977 Changed the union discriminators of the protocol files from enums to
1978 ints paired with #defines.
1980 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1983 *Changed operator in the RPN structure to 'roperator', again to avoid a
1986 Fixed problems in Explain decoders/encoders.
1988 --- 1.0pl2 1995/12/6
1990 Memory bug in log module fixed.
1992 --- 1.0pl1 1995/12/5
1994 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1996 Bug in Explain DatabaseInfo module fixed.
1998 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2002 The shift to v1.0 signals that we now consider the *core* functionality
2003 of YAZ reasonably stable (the core being more or less equivalent to
2004 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2005 tested (Explain not at all - though that will happen soonish).
2007 Minor changes to code to support Windows port.
2009 Various minor changes after we're getting to use GRS-1 & co. more.
2011 Added Espec-1 format.
2013 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2014 of the protocol and it cannot be selected when encoding (maps into 'string'
2015 when decoding). Needed to talk to some servers.
2017 Demo client can request simple element set names.
2019 Added Diagnostic Format encoders/decoders.
2021 Added simple Close handling to frontend server (no hooks for resource
2022 reporting yet), and demonstration client.
2024 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2026 --- 1.0b3 1995/08/24
2028 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2029 handled incorrectly when records were requested in the searchResponse. This
2030 will only affect you if you use the frontend-server.
2032 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2033 Test-client will ask for and print GRS1. Ztest will return dummy records
2036 Added Explain encoders/decoders to the service-level API. Untested.
2038 Added Extended Services: Item Order encoders and decoders to the Service-
2039 level API. Untested. We could use a recent copy of the pertinent bits
2040 of the ILL protocol to add those bits.
2042 Added diagnostic format 1 encoders/decoders to the service-level API.
2045 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2046 odr_cons.c, which causes a more correct output.
2048 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2049 was always set to 0 when no records were requested in the searchRequest.
2051 * Added better external-handling. This shouldn't harm old code that
2052 *encodes* externals. It can break code that looks for a
2053 'single-ASN1-type' representation, since those types that are known
2054 are now decoded immediately. Look at the SUTRS sample code in
2055 seshigh.c and client.c. Documentation updated.
2057 Handling of structured records in bend_fetchresponse. Length -1 marks
2058 structured record, type is deduced from format field.
2060 --- 1.0b2 1995/06/27
2061 Fairly quick maintenance release to add SUTRS support.
2063 Fixed handling of SUTRS records in the demonstration client.
2065 * Added format field to the bend_fetchrequest and bend_fetchresponce
2066 structures of the backend API (frontend server). When the record is
2067 returned, the value of the format field is mapped to an OID. The
2068 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2069 of the record. The special value VAL_NONE in the bend_request means
2070 that no specific format was requested by the client. Documentation
2071 updated accordingly. Test server (ztest) will return a fixed dummy
2072 SUTRS record if your client requests SUTRS.
2074 Documentation updated accordingly.
2076 You can now set external libraries and RANLIB support in the top-level
2080 First public release.
