1 Fix to ZOOM-C so that transparent reconnection is properly handled on
2 connections that are in asynchronous mode.
4 Fixed compilation on OpenBSD 4.0.
6 Large strings in GRS-1 records are now properly displayed in yaz-client.
8 Added character conversion support for "advancegreek"; based on patch from
11 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
12 sequence is met. Before the error was not set so it would be unknown.
14 Adjust yaz-marcdump MARC reader so that it skips until record separator
19 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
20 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
21 fd_set structure used as a bitmask for the FDs to be selected on.
23 Using ACX_PTHREAD macro to check for POSIX threads.
25 Fixed have-vsnprintf check.
29 Fixes for configure on BSD. Bug #900.
31 Added snprintf/vsnprintf wrappers for systems that don't have
32 limits (heavens forbid).
34 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
35 created before all previous tasks were completed and removed from the
36 task queue, the new task could be removed by a mistake.
38 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
40 Implemented pass-through CQL-to-PQF conversions. Bug #861.
42 Fixed bug #832: Problem with MARC/charset in yaz-client.
44 Fixed bug #668: save command line history for yaz-client.
46 Fixed bug #830: pkg-config support.
50 Extended ZOOM result set options with two options that may be read by
51 a client: resultSetStatus and presentStatus with values as specified for
53 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
55 Fixed bug #827: Using SSL fails on Debian etch.
57 Fixed bug #826: Weird looking chars for set of MARC records.
59 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
60 that is treated as an ItemOrder with itemRequest being an XML document
61 external. The value of "doc" is the content.
63 Extended the GFS search facility. New member of bend_search_rr
64 'estimated_hit_count' signals that hits is known to be an estmate
65 (higher or lower than real hit count). New member 'partial_resultset'
66 signals that the search was partial (hit count is lower or equal than
67 real hit count). For Z39.50, the information is stored in resultSetStatus
68 member of SearchResponse APDU. For SRU, the information is signalled
69 via SRU diagnostic 59: "Result set created with valid partial results
72 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
76 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
78 Added ZOOM_connection_peek_event.
80 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
81 the following new functions:
82 ZOOM_event_nonblock, ZOOM_connection_process,
83 ZOOM_connection_get_{socket,mask,timeout},
84 ZOOM_connection_fire_event_{timeout,socket}.
85 The existing blocking event handler, ZOOM_event, is a wrapper for the
86 + blocking ZOOM_event_sys_{poll,select}.
88 Implemented function ccl_xml_config which parses XML version of CCL
89 configuration (bug #798).
91 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
93 Added timings utility (yaz/timing.h)
97 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
100 Fixed bug #779: Rotation of apdu.log fails.
102 Fixed for character set conversions:
103 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
104 Honor G1 set in MARC-8 decoding.
106 --- 2.1.42 2006/12/17
108 Fixed bug #775: char conversion does not handle Alternative UTF-8
111 Implemented function yaz_marc_read_line which parses MARC line format
112 records. There is a wealth of formats out there. So far, this function
113 reads line records produced by yaz_marc_write_line.
115 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
116 more generic and easier to remember(!) options: -i format and -o format
117 which specifies input format and output format respectively - where
118 format is one of "marc", "marcxml", "line", "marcxchange".
120 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
121 does not print anything except warnings for records.
123 For yaz-marcdump, added support for MARC split into files (-s) with a given
126 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
127 spec, at http://www.loc.gov/standards/sru/record-update/
128 This has changed the binary layout of the following structs:
129 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
130 bend_update_rr . Patch by Ko van der Sloot.
132 Added GFS utility function bend_assoc_is_alive which returns 1 if
133 association is still alive (client is connected); 0 otherwise (client
134 closed connection). This allows busy servers to stop working for
137 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
138 been a separate piece of software. This version of ziffy has been modified
139 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
141 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
143 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
144 Client code may now interrogate options such as "init_opt_sort" to
145 find out whether the server claims to support various options.
147 --- 2.1.40 2006/11/27
149 Added utilities yaz_{set,get}_esn to set/get element set name from
152 Removed the build of libyazthread.la. The libyaz.so is the threaded version
153 of YAZ and has been so since YAZ 2.1.10.
155 Implemented ZOOM_record_error which returns error information for
156 record (surrogate diagnostic).
158 --- 2.1.38 2006/10/31
160 Updates for SRU Update by Ko van der Sloot:
161 1. Changed name from "operation" to "action"
162 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
163 versions in the code, marked as 'backward compatible'.
164 3. Added diagnostics for SRU Update.
166 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
168 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
170 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
172 For GFS, fixed problem with SRU diagnostic 'First record position out of
173 range' being issued for 0 hits.
175 zoomtst10 part of Windows Build.
177 --- 2.1.36 2006/10/13
179 Implemented yaz_filepath_comp which splits a path into file path
180 components (required by Zebra 2.0.3+).
182 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
183 BSD inspired license until now so this should not have any real impact on
184 anybody. See http://www.opensource.org/licenses/bsd-license.php
186 Fixed bug #687: Missing log lines.
188 Fixed bug #678: CQL to PQF translation does not preserve double-quote
191 Fixed bug #689: SRU diagnostics to be added.
193 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
194 whether a connection is idle (no more work do do).
196 --- 2.1.34 2006/10/04
198 Change type of optval from long to int for invocation of setsockopt with
199 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
201 Added support for specifying the max log file size for the Generic
202 Frontend Server. The size is given with option -r.
204 --- 2.1.32 2006/09/21
206 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
208 --- 2.1.30 2006/09/17
210 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
213 Fixed bug in Generic Frontend Server that could cause a server to stop
214 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
216 For the generic frontend server, the maximum record size is used as maximum
217 size of incoming packages (SRU + Z39.50). The value until was previously
218 only used in Z39.50 Init negotiation and, later, in a session controlled
219 sizes of records returned. This is controlled using -k option. It can be
220 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
222 --- 2.1.28 2006/09/04
224 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
227 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
229 New option for yaz-marcdump -lpos=value which allows setting a portion
230 of MARC header to a certain value.
232 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
234 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
235 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
237 --- 2.1.26 2006/08/15
239 Fixed problem with SRU mode type (soap, get, post) for yaz-client
242 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
244 --- 2.1.24 2006/08/08
246 Fixed MARC ISO2709 encoding routines to deal with character set
249 Minor changes to GFS logging. Database included in search request log
252 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
253 cached/multiple records.
255 Shared libraries are built by default on Unix+configure.
257 Changed cql2pqf transformation to use a different evaluation order. The
258 new order is: always, relation, structure, position, truncation, index
259 and relationModifier. Old order was: always, relation, relationModifier,
260 structure, index, position, truncation. Note that the the latter ones
261 override former ones for identical attributes.. The new scheme means that
262 it is possible to override any existing attribute with a relationModifier.
263 And also that it is possible to override everything for the index rule
264 (except the ones listed in relationModifier). No order is perfect but this
265 one, we believe, covers more real cases.. The "always" should have been
266 called "default", since the attributes there can be overridden with all
269 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
270 compilation phase, but also for yaz-config --cflags output. This allows
271 us to have public headers with Libxml2 stuff in them . It should also,
272 eventually, make Libxml2 checks redundant in packages using YAZ, such
275 --- 2.1.22 2006/06/15
277 Changed SRU update structure bend_update_rr so that SRU diagnostics are
278 stored in uri, message and details.. Previously diagnostics were stored
279 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
280 compatibility.. but he's probably the only one affected, so.
282 Added support for CCL, compiled on the client side, in ZOOM-C. This
283 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
284 input; the resulting query objects can be used for for searching with
285 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
287 YAZ' configure searches for OpenSSL by default.
289 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
290 SL_CTX_use_certificate_file. See
291 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
292 for more info. Thanks to Ko van der Sloot.
294 --- 2.1.20 2006/06/02
296 Bug #600: SRU GET, POST support for yaz-client. Introduced
297 command 'sru' which selects method SOAP/GET/POST.
299 Allow missingValueAction to be specified for the sortspec string -
300 function yaz_sort_spec. By default, the missing value action is null.
301 Use ! to specify "abort". Use = followed by stringvalue to specify default
304 Ensured that Present-handler (if defined) is called in GFS before any call to
305 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
306 searchRetrieve requests.
308 Documentation for YAZ is now based on the Docbook XML/XSLT using
309 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
310 is no longer depending on jade/openjade or docbook-to-man scripts.
311 PDF is no longer part of the distribution - but can optionally be
312 made using DSSSL/jadetex or FOP.
314 Added retrieval handling support in Generic Frontend Server to support
315 conversion between MARC/XML as well as XSLTtransforms. See
316 etc/yazgfs.xml for an example.
318 Added Authentication support to Generic Frontend Server in SRU
319 mode. Authentication using HTTP Basic is supported, as is the use
320 of 'x-username' and 'x-password' parameters in the request itself.
322 Added support for a new character set MARC8s identical to MARC8 except
323 that it converts combined characters to single Unicode characters in the
324 Latin-1 range (when possible).
326 --- 2.1.18 2006/04/24
328 ASN.1 compiler 0.4: generates brief Doxygen file header for
329 generated .h/.c files.
331 Utility yaz_iconv now supports conversion to MARC-8.
333 New facilities for the MARC module. The reading - and writing of
334 content are separate methods for the yaz_marc_t handle. The following
335 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
336 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
337 format). Write functions have prefix yaz_marc_write_.. The existing
338 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
339 available. Removed support for OAI-MARC and simplexml (not the
340 simplexml from PHP5).
342 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
343 to be returned for this connection.
345 --- 2.1.16 2006/03/31
347 Allow multiple languages and charsets to be specified with
348 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
349 negcharset iso-8859-1,utf-8
351 Translation of proximity nodes from CQL into PQF now works.
353 Moved to automake 1.8, 1.9.
355 Added function yaz_log_set_handler which allows a log handler to be
356 installed. This handler will be called for all log messages. Output
357 to file is also produced; but that can be disabled by passing NULL
358 fname to yaz_log_init_file.
360 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
362 For SRW (including GFS), accept application/soap+xml as content-type
365 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
366 produces NO stylesheet reference even if a default stylesheet is specified
369 --- 2.1.14 2006/03/14
371 Updated Windows package to include yazd.dll + yazd.lib for the
372 Development component.
374 If the environment variable YAZ_LOG is set, then it is used as a
375 string indicating the default level of logging to use if not
376 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
377 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
378 used as before. So, for example, to omit warnings from YAZ logging,
381 cql_transform() now map structure and other attributes before indexes,
382 so that index-specific structures and other attributes can override
383 defaults. So now a combination of mapping specifications such as:
385 index.dc.date = 1=date-modified 4=5
386 does the right thing.
388 cql_transform() now also respects the "always" mapping specification,
389 which establishes an initial set of attributes to be used for all
390 terms except where overridden by more specific attributes associated
391 with the index, relation or modifier.
393 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
394 which mode to use; one of "post", "get" or "soap" (SRW, default).
396 Fixes for yaz_iconv routines: changed trie-based character set conversions
397 to use only non-negative values for bit fields due to Sun's C compiler not
398 supporting negative values.
400 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
401 sequences where not read correctly. Fix by Rustam Usmanov.
403 Updated win/makefile to use options, settings which makes things
404 compile with VS C 2005.
406 --- 2.1.12 2006/02/01
408 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
410 In ZOOM socket code, use select instead of poll on MacOSX.
412 ZOOM-C now support client-side compilation of CQL into RPN that is
413 sent to the server, enabling CQL to be used against all Z39.50
414 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
415 ZOOM_query object, and submit it using ZOOM_connection_search().
416 The CQL-to-RPN translation uses a configuration file, the name of
417 which must be specified in the Connection's "cqlfile" option.
419 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
420 function, which takes as its start-term parameter a ZOOM_query object
421 (which may have had either CQL or RPN set into it).
424 --- 2.1.10 2005/11/29
426 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
427 GFS to support this as well. Backend handler, bend_srw_update, does the
428 update work. Code contributed by Ko van der Sloot.
430 Allow retrieval of Search Result-1 information in ZOOM by the use of
431 options that are attached to a result set. ZOOM documentation updated
434 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
435 UTF-8 conversion. Patch by Raj Patel.
437 Added option -m to GFS to control formatting of timestamps in log file.
439 Added 'exit' as synonym for 'quit' in yaz-client
441 Added support for specifying SRW resultSetId + resultSetIdleTime in a
442 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
443 for the new members. Patch by Ko van der Sloot.
445 Added support for SRU POST. It is supported for content-type
446 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
448 Do not build the separate Multi-threaded (MT) library libyazthread.la.
449 Instead make the library libyaz.la multi-threaded. Threading as a whole
450 can still be disabled by configure option --disable-threads. Previosly,
451 with older GLIBCs there were problems with MT libs under Apache. This
452 has now been fixed a long time ago.
454 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
457 CQL module modified to be case insensitive for relations/indexes/operations.
459 Fixed bug in CQL transform code: incorrect value relationModifieder
462 Added 'show all' command for yaz-client which retrieves all results
465 Added new yaz-client, xmles, which takes a (private) OID and
466 a document to be sent as an extended service request.
468 Describe new yaz-client commands wait_response and set_auto_wait.
470 Increase TCP/IP listener backlog from 3 (which I am guessing was
471 copied from the SunOS manual entry way back when) so SOMAXCONN, so
472 that the socket will queue as many incoming connections as it's able
473 to handle ongoing connections. In other words, it will never now
474 refuse a connection that it would be able to handle merely because
475 it's not got around to accepting() enough of the pending connections
476 yet. This is the behaviour anyway under Linux, where the listen()
477 argument is ignored; but not under BSD and on systems such as
478 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
479 YAZ-based servers should now be uniform across operating systems in
482 yaz-marcdump uses 64-bit file access on some systems. This is enabled
483 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
484 This allows yaz-marcdump to read large MARC batches (>2 GB).
486 Modified all YAZ source files - except the source which is auto-generated
487 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
490 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
491 corresponding to the existing *_setl() function. These allow option
492 values containing arbitrary valuues.
494 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
495 ZOOM_resultset_sort() in new applications. Its behaviour is identical
496 except that it returns an indicator of whether or not the sort
497 criterion was accepted (0 for OK, -1 for invalid).
501 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
502 MARC output rather than returning "new" buffer.
504 yaz-client warns about unknown init options.
506 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
510 Added support for SRW sort in Generic Frontend Server. Patch
511 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
512 sortKeys - or NULL if none is provided.
514 Fixed bug #307: It was impossible to specify indefinite/no timeout
515 for ZOOM_event. Special timeout value -1 now means indefinite timeout
518 Added support for multiple languages and charsets to be specified in
519 ZOOM. Each charset/language is separated by a blank. If negotiation is
520 in effect in init-response, Option
521 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
522 Code based on patch by Vasiliy Osadchuk.
524 Fixed bug #306: infinite recursion that occurred when calling
525 yaz_log_level_init as the first call (before other log level or
528 Fixed bug in scan handling in front end server: if preferred-Position-In-
529 Response was non-present, a NULL pointer referece was performed.
533 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
534 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
535 now defined for all those error codes. So instead of putting 109 in
536 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
537 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
539 Modified the yaz-marcdump utility to skip garbage bytes between MARC
542 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
544 Program yaz-client now exits and produces an error message if multiple
545 Z39.50 servers are specified on the command line (none or one allowed
548 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
553 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
555 Fixed bug #272: Preserve spacing for CCL terms.
559 Added support for virtual hosts and multiple backend servers for
560 the YAZ frontend server. The configution is XML based and
561 support specificition of CQL to RPN mappings and explain information.
562 See section "Virtual Hosts" in the YAZ manual.
564 Extended OPAC display utility. OPAC display utility renders
565 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
566 to supplement yaz_marc_decode_wrbuf.
568 Fixed a bug in MARC decoder that could caused it to crash for some
569 invalid MARC records. More diagnostics and warnings where added in
570 XML output (warnings, etc are stored in comments).
572 --- 2.0.34 2005/02/08
574 Fixes for UNIX domain sockets. Bug #261.
576 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
578 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
579 Added yaz_marc_subfield_str which defines subfield lead string which is
580 used in YAZ_MARC_LINE format. Default string is blank+$. Added
581 yaz_marc_endline_str which defines end of fields string used in
582 YAZ_MARC_LINE format. Default string is newline.
584 Experimental support for MarcXChange. This format can be produced
585 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
586 http://www.bs.dk/standards/MarcXchange.xsd
588 Added yaz-client commands scansize that sets maximum number of
589 entries to be returned by scan.
591 --- 2.0.32 2005/01/11
593 Added support for SRW scan in yaz-client and Generic Frontend Server.
595 * Added whereInList member to SRW Scan Term.
597 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
599 Fixed NMEM system to return aligned blocks on the smallest boundaries
600 that are suitably aligned for all possible types on the particular
601 architecture YAZ is being built for.
603 --- 2.0.30 2005/01/04
605 Fixed numerious warnings that was issued with newer versions of GCC.
607 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
608 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
611 Make YAZ Generic Frontend Server slightly faster.
613 Enhance (and reduce) logging for Generic Frontend Server.
615 Revert YAZ log system so that it flushes every write operation
616 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
618 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
619 instead of LOG_, due to name clash with syslog(3). LOG_ are still
620 present. New applications should define YAZ_USE_NEW_LOG=1 - this
621 will effectively disable old definitions.
623 --- 2.0.28 2004/11/09
625 Added yaz_log_time_format which specifies log format using
628 Added yaz_log_module_level which returns mask for a module. Value
629 is non-zero mask a if module is enabled; zero if disabled.
631 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
632 in include/yaz/cql.h.
634 Fixed bug #176: Dont throw diagnostics on empty SRU args.
636 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
638 Fixed bug #172: RPM builds does not enable SSL.
640 Doxyfile.in part of dist. Doxyfile generated by configure.
642 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
643 are given and the corresponding component does not exist.
645 Extend CCL documentation in YAZ reference. Describe r=r.
647 --- 2.0.26 2004/10/01
649 Fixed MARC->MARCXML conversion to properly deal with
650 fields, subfields, indicators having non-ASCII characters.
652 Fixed MARC->MARCXML conversion so that ASCII control characters
653 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
656 Added YAZ GFS support for conversion from Z39.50 surrogate
657 diagnostics to SRW surrogate diagnostics.
659 Bug fix: YAZ GFS did not return schema in explainResponse.
661 --- 2.0.25 2004/09/30
663 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
664 now converts recordSchema to elementSetName as well as schema URI.
666 Fixed bug in COMSTACK that prevented HTTP request packages from being
669 --- 2.0.24 2004/09/29
671 Added CCL facility r=r "range" which is similar to r=o "ordered" but
672 does not require white-space before and after the dash in a range, e.g.
673 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
676 Fixed a few AC_TRY_LINK configure tests that did not operate properly
677 due to new GCC removing "redundant" code.
679 Added yaz-client commands scanpos and scanstep that sets preferred
680 position and step-size for scan.
682 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
684 Added CCL utility ccl_qual_buf which parses one or more CCL
685 spec lines in a buffer.
687 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
688 of name and value - ignoring empty lines and comments.
690 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
692 Added odr_get_element_path which returns current element path for an
693 ODR handle. This utility is useful in error handling or user-defined
696 Added ODR_PRINT utility odr_set_stream which is is a more generic
697 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
698 to a write function and pointer to close function. The close function - if
699 non-NULL - will be called during odr_destroy.
701 Fixed bug in CCL parser where truncation char was not removed from
702 right side when truncation=both was in effect.
704 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
707 --- 2.0.23 2004/08/11
709 Fix buffer overrun in CQL parser when dealing with proximity (%).
711 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
712 to UTF-8/UCS conversion is now only based on codetables.xml.
714 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
716 --- 2.0.22 2004/08/06
718 Add support for more "commit changes" in ZOOM (uses Extended Services).
720 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
723 Yet another small fix for configure of SSL.
725 --- 2.0.21 2004/05/14
727 Fix SSL libs for configure when --with-openssl=DIR is given.
729 --- 2.0.20 2004/05/10
731 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
733 SSL comstack now uses yaz.pem certificate file on server side
734 by default. Certificate filename can be configured by calling
735 comstack function cs_set_ssl_certificate_file before cs_bind is used.
737 Fix bug regarding multiple calls to ZOOM_connection_connect.
739 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
741 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
742 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
744 ZOOM now allows inspection of X509 peer certificate for verification.
745 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
747 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
748 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
749 as "modular" but it simplifies things.
751 Added cs_get_peer_certificate to that returns peer X509 PEM.
753 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
754 NULL if SSL is unavailable.
756 Documentation about MARC decoding tools.
758 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
760 --- 2.0.19 2004/03/30
762 Rename CHANGELOG to NEWS to follow GNU style packing.
764 Fix bug with missing initialization of member in init_diagnostics.
765 This bug affects threaded version of GFS server.
767 --- 2.0.18 2004/03/20
769 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
772 Ensure zlib.dll is packed with Windows install.
774 --- 2.0.17 2004/03/17
776 Fix encoding of xsd:string to use text instead of CDATA.
778 Fix endless loop in CQL parser with unbalanced ".
780 Use a more compact way to store MARC-8 conversion tables.
782 --- 2.0.16 2004/03/16 Debian only
784 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
787 Update CQL parser to use new CQL 1.1 modifiers for booleans and
792 --- 2.0.15 2004/03/01
794 Another fix for decoding of XML packed records.
796 --- 2.0.14 2004/02/25
798 Fixes for Chunked encoding. White space not ignored after length spec.
800 Update NS and use default NS for SRW diagnostic elements.
802 --- 2.0.13 2004/02/23
804 Implement ZOOM_resultset_cache_reset which resets record cache.
806 Implement ZOOM_resultset_sort which sorts a result set.
808 Implement chunked HTTP transfer.
810 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
812 --- 2.0.12 2004/02/16
814 Added member 'schema' to bend_explain_rr structure so that backend
815 can specify explain record identifier. Defaults to Zeerex 2.0.
817 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
819 --- 2.0.11 2004/02/16
821 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
824 Added init command for yaz-client which sends "extra" init request.
826 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
827 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
829 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
831 Make ZOOM error code for "invalid query".
833 Fixed compilation for SSL which wasn't properly enabled for all platforms.
835 --- 2.0.10 2004/02/05
837 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
840 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
842 Added option -p <file> to make Generic Frontend Server to write PID file.
844 Added option -D to put Generic Frontend Server in background on its own.
846 Make ZOOM C recognize option "password". If unset, "pass" is used
847 (for backwards compatibility).
849 Fixed a bug in Generic Frontend Server that could make it crash if a
850 client sets characterSetNegotation bit, but didn't pass negotiation stuff
853 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
854 Must be issued before open, in order to be in effect.
856 --- 2.0.9-6 2004/01/12 Debian/Windows
858 Make the SRU server more picky WRT unknown params, etc.
860 Bug fix: ZOOM scan response didn't return displayTerm - when present.
862 New YAZ client command, options, that sets Z39.50 options.
864 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
865 options from a string of tokens (one token for each option bit).
867 Update SRW diagnostic code messages.
869 --- 2.0.9-5 2004/01/07 Debian/Windows
871 Handle user defined stylesheet for SRW/SRU.
873 --- 2.0.9-4 2004/01/06 Debian/Windows
875 Fix bug in decoding of Content-Length.
877 --- 2.0.9-3 2004/01/06 Debian/Windows
879 Fix a bug with decoding of XML packed records.
881 --- 2.0.9-2 2004/01/05 Debian only
883 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
885 Fix bug in SRW/SRU diagnostics decoding.
889 Fixed bug in Generic Frontend Server which could drop records exceeding
890 preferred message size. Reported and fixed by Irina Dijour.
892 Fixed calculation of package size for structured records in Generic
893 Frontend Server. Reported and fixed by Irina Dijour.
895 Fixed namespace for SRW/SRU diagnostics.
897 Fixed SEGV in yaz-client that occured for HTTP connection errors.
901 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
902 this version is incompatible with version 1.0 and older YAZ SRW/SRU
905 CQL changes to reflect recent changes to the specification:
906 * Documentation talks about context sets instead of index sets.
907 * Documentation talks about indexes instead of qualifiers.
908 * The CQL-to-PQF transformer's configuration file now uses
909 "index.set.name = <attributes>" instead of the old form
910 "qualifier.set.name = <attributes>". (Both forms are still
911 understood but the latter is deprecated.)
912 * CQL terms with no explicit index specified are now interpreted as
913 cql.serverChoice instead of srw.serverChoice (which of course
914 behaves exactly the same.)
918 MARC conversion can now generate ISO2709 output in another
919 character set. yaz-marcdump uses this facility if you invoke it
922 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
923 functions from there can be used from C++.
927 Frontend server now transfers memory from decoded packages to stream
930 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
931 references to show up.
933 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
934 the ZOOM Abstract API. The older names for the same options are still
935 also supported for the benefit of old applications.
937 ZOOM-C supports "implementationId" and "implementationVersion" options
938 to go along with "implementationName". These allow the user code to
939 specify identification strings to be sent to servers.
940 Add OID for the new ExtLite attribute set.
942 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
943 as requested/supplid by Ere Maijala <ere@atp.fi>
945 For generic frontend server, reverse the order of
946 "toolkit-supplied / application-supplied" strings sent as implementationId,
947 Name and Version. Also, remove the spaces around the slash. This brings
948 the GFS in line with the behaviour of ZOOM-C on the client side.
950 Add function ZOOM_scanset_display_term.
952 yaz-client shows scan displayTerm if present.
954 Utility yaz-iconv is now installed by default along with the man page
957 Extend configure check for OpenSSL to use pkg-config where available (such
960 Incorporate patch by Morten Bogeskov which allows a Unix file socket
961 server to specify uid/gid/mask for socket using the format
962 unix:[user=uid,][group=gid,][umask=mask,]file=path
963 If file= is omitted the existing format is assumed, e.g.
965 in which case the mask is 0666 (rw for everybody).
967 Major restructure of YAZ source. All source in libyaz is in src directory.
968 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
969 util (utility programs such as ASN.1 compiler, yaz-marcdump).
971 Added man page for utility yaz-marcdump (used to be called marcdump).
972 yaz-marcdump is installed by 'make install'.
974 Fixed a memory leak in Generic Frontend Server that occurred when decoding
975 of incoming package failed.
977 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
979 Change prototype of odr_perror: add const to message string.
981 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
983 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
984 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
985 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
986 DNS lookup. There should not be any compatibility problems with this
987 assuming that blocking=1 or 0 is used.
989 Fix bad reference in UNIX comstack in function cs_addrstr.
991 Fix for compilation on AIX.
993 The generic front-end server (server/seshigh.c) now supports returning
994 Init diagnostics to the client in User-information-field, in
995 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1000 Allow any CQL relation (not just all,any,exact,scr).
1002 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1003 that features the same UI.
1005 Implemented command update0 in YAZ client which is equivalent to
1006 update but uses old of Ext Update ASN.1.
1008 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1009 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1010 Previously no OID was used for this info.
1012 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1013 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1014 returns 'malformed search term' otherwise.
1016 SortResponse member resultCount now set to NULL in sort handler of
1019 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1022 Add three new utility functions for translating OIDs between various
1023 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1024 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1025 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1026 char *oid_to_dotstring(const int *oid, char *oidbuf);
1027 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1029 Reverted modifications for ES Update definition for z_IU0Update
1030 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1031 is back to YAZ 2.0.2.
1033 String value attributes for CCL parser.
1035 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1036 which their FirstSearch server returns in Init responses, sometimes
1037 carrying useful diagnostic information when Init fails. This has the
1038 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1039 "z39.50/oclcui.asn", where its definition is somewhat different from
1040 what OCLC document on their web-site, as required to interoperate with
1043 Support for anonymous authentication in yaz-client. Use the command
1046 * Fix the OID of the Index Data-local "admin" Extended Service from
1047 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1048 the 1000, which indicates a locally-defined OID, was a mistake.
1050 --- 2.0.3 2003/06/20
1052 Fix CCL directive @case handling so that it affects string match for
1053 both CCL keywords and qualifiers.
1055 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1056 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1057 Decoder has been updated with ASN.1 changes as listed in
1058 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1059 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1060 z_IUUpdate, remains unchanged.
1062 ZOOM_record_get may now return a record in a specific character set.
1063 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1064 "from" is the character set of record as returned by target. "to" is
1065 the character set to be returned. If omitted, "to" is UTF-8.
1067 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1069 New ODR utility, odr_getelement, which returns name of element for
1070 which encoding/decoding failed.
1072 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1073 in cases where a required element was omitted.
1075 Bug fix: some MARC8 sequences were not converted.
1077 New ZOOM option "step" which specifies number of records to be
1078 retrieved in one chunk. Used in conjunction with "start" and "count".
1080 SRW support for yaz-client. Use scheme http: to use it, e.g.
1083 yaz-client no longer does (un)intelligent character set conversions
1084 by default. Can be enabled with charset and marc_charset commands.
1086 xmalloc trace fix for 64-bit systems such as DEC alpha.
1088 Solaris 2.6 compile fix.
1090 New function, cql_strerror() translates SRW error codes, as returned
1091 by cql_transform_error(), into human-readable English strings. Used
1092 in yaz-client diagnostics when appropriate.
1094 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1095 converts it into a type-1 query which is sent to the server. This
1096 makes CQL available for use with all Z-servers, as opposed to the tiny
1097 minority that can handle CQL queries themselves.
1099 --- 2.0.2 2003/04/28
1101 New Debian package layout similar to the Redhat Package layout.
1103 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1104 and search result respectively.
1106 --- 2.0.1 2003/04/25
1108 Redhat package is now several packages: libyaz (runtime libraries),
1109 libyaz-devel (development and documentation, and yaz (utility programs).
1110 Package spec file by Morten Bøgeskov.
1112 New member 'schema' in struct bend_fetch_rr which the name of requested
1113 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1114 handler MAY set this to reflect the schema of the returned record.
1116 New member 'display_term' in struct scan_entry. GFS now sets member entries
1117 and allocates scan entries to be filled by user scan handler. In previous
1118 version, entries member was allocated by the scan handler. That still works,
1119 but the GFS will ignore member display_term - assuming it was NOT set by
1120 the handler. The fact that the GFS now allocates the entries both allows
1121 for new members and makes a scan handler easier to write.
1123 Fix CQL lex buffer overflow.
1125 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1126 SRU default recordPacking is string.
1128 SRU protocol support for frontend server.
1130 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1132 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1134 Added scan for the ZOOM shell (zoomsh).
1138 * String Identifers for Schemas (Amendment 5).
1139 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1140 Old definition for schema
1141 Odr_oid *schema; /* OPT */
1146 Z_InternationalString *uri;
1147 #define Z_Schema_oid 1
1148 #define Z_Schema_uri 2
1151 * resultCount parameter to Sort Response (Amendment 1).
1152 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1154 Support for SRW 1.0 over HTTP. This is an optional feature and
1155 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1158 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1159 on the same port. SRW SearchRetrieveRequests are mapped
1160 to bend_init,bend_search,bend_fetch,bend_close.
1162 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1164 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1165 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1167 ZOOM connections are SRW based if schem http is used for hostname
1168 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1169 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1171 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1172 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1173 distance=n, order=true/false, relation=le, prox unit=word. If
1174 n is omitted, distance 1 is used.
1176 Fixed problem with C compiler include path in wrong order.
1178 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1179 on Solaris. Patch from Ko van der Sloot.
1181 New MARC decode API. All new functions operate on a yaz_marc_t
1182 handle. The most important new functions are: yaz_marc_create,
1183 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1184 decode and destroy respectively. Decoder can produce formats
1185 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1186 include/yaz/marcdisp.h.
1188 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1189 to UTF-8, UCS-32, wchar_t or Latin-1.
1191 * Prototypes for yaz_iconv_-functions moved to separate header
1192 include/yaz/yaz-iconv.h.
1194 Make a few private functions 'static' in unix.c. This prevents
1195 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1197 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1198 are set when Init Response is received.
1200 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1201 but returns diagnostic set as well.
1203 New function yaz_strerror which is a portable wrapper for
1204 strerror/strerror_r/GetLastMessage.
1206 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1207 is returned for MARC. If type is "oai", then OAI MARC is returned.
1209 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1212 --- 1.9.2 2002/11/26
1214 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1216 Fix bad race conditions on SIGTERM and terminate gracefully in
1219 Move retrieval (data1) module to Zebra since nobody seems to be
1222 Add GRS-1 render for ZOOM using same format as yaz-client.
1224 --- 1.9.1 2002/10/05
1226 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1228 Fix broken ESpec handling in data1 module.
1230 SGML reader parses comments and makes them part of the data1 tree.
1232 Added several type casts so that YAZ compiles as C++ code.
1234 ZOOM didn't handle PDU encoding failures properly.
1236 Added more Bib-1 diagnostics (approved extensions).
1238 GNU configure: better check for iconv.
1240 More portable use of accept, getpeername. Check for socklen_t. Use
1241 int/size_t if socklen_t is not defined.
1245 PQF parser rejects bad queries - including those with extra
1246 characters in them. PQF parser used to silently ignore that.
1247 Cleaner API for PQF added, which allows you to get detailed
1248 error information for bad queries (see yaz/pquery.h).
1250 Fixed bug in ZOOM_record_get for type "database".
1252 Implemented mini iconv library supporting conversions between
1253 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1255 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1257 --- 1.8.9 2002/08/20
1259 Fixed ZOOM C record cache so that preferredRecordSyntax and
1260 elementSetName is used to check for already fetched records.
1262 --- 1.8.8 2002/08/02
1264 Added three members in bend_initrequest structure to facilitate
1265 character set negotiation.
1267 Fixed a bug in frontend server that could cause indefinite
1268 loops under rare conditions.
1270 Revised character set utilities (charneg.h) so that encoding
1271 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1273 For PQF, directive @term <type> sets term type for Scan/Search.
1274 Here <type> is general, string, numeric, null. The term type
1275 is inherited - just like @attr.
1277 New call odr_set_charset that sets character set conversion for
1278 international-strings on a ODR stream. Prototype is:
1279 int odr_set_charset(ODR o, const char *to, const char *from);
1280 The InternationalString is still represented as C string in YAZ
1281 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1282 won't). On the protocol level, you can use any encoding.
1284 Support for UNIX sockets in ZOOM.
1286 Solaris recv sometimes returns errno == ENOENT. It is treated as
1287 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1289 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1290 both client and server. Code by Morten Bøgeskov.
1292 --- 1.8.7 2002/05/22
1294 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1295 that they can be used directly from Visual Basic. You must recompile
1296 your windows APP if you're using ZOOM.
1298 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1299 Commands "lang" and "charset" sets language and character set respectively.
1300 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1301 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1303 Attributes from multiple CCL fields may be OR'ed rather than merged
1304 using directive "@field or". Fields are still merged by default -
1305 equivalent to "@field merge".
1307 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1310 Fixed bug in zget for parameter ExtendedServicesResponse.
1314 --- 1.8.6 2002/03/25
1316 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1318 Client displays USR.1:SearchResult-1 (hits per term).
1320 Additional Search Info for search in Generic Frontend Server.
1322 Fixed CCL parsing of "field=s".
1324 WIN32 installer - using the excellent NSIS software from nullsoft.
1326 Fixed CCL parsing of "field = - <number>".
1328 Added function yaz_marc_decode that decodes MARC for line mode
1329 display or XML (similar to that used by JZKit).
1331 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1332 Z39.50. But ISO/ILL was, however.
1334 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1335 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1338 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1340 --- 1.8.5 2002/02/03
1342 New YAZ client features: Command completion and new commands:
1343 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1344 Code provided by Jacob Poulsen.
1346 New call oid_trav, that visits all registered OIDs via callback.
1348 Function ZOOM_record_get now returns const char pointer rather than
1349 void pointer. It saves a lot of type casts.
1351 For YAZ client, command "auth" now allows you to set authentication
1352 in IdPass style. It is enabled when three tokens are given - order
1353 is user, group and password.
1355 Fix memory leaks in MARC record handling for ZOOM.
1357 New option for YAZ client, -k <kilobytes> that sets
1358 maximum record size. Similar to -k option for generic frontend
1359 server and yaz-ztest.
1361 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1363 Prefix query parser reports "fail" when bad attribute set is given.
1365 Fix in MARC decoder. Proximity logging. Fix for attribute set
1366 in scan handler for server. Patches by Shigeru Ishida.
1368 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1371 Configure option --with-openssl=<dir> now works when a directory is
1372 specified. Patch provided by Morten Bøgeskov.
1374 New option for YAZ client, -u <auth>, that sets authentication.
1376 ZOOM fix: error information was sometimes "missing", since error
1377 was cleared/reset too when it shouldn't.
1379 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1381 --- 1.8.4 2002/01/04
1383 Scan for ZOOM API. New object ZOOM_scanset. New functions
1384 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1385 ZOOM_scanset_destroy.
1387 New ZOOM function, ZOOM_connection_last_event, that returns type
1388 of last event (such as "receive data", "send data", "apdu received",
1391 New ZOOM option, schema, that specifies schema for retrieval.
1393 New CCL feature. Qualifiers can be aliases for one or more
1394 other qualifiers (if more than one is given, OR is used).
1396 ZOOM uses named result sets if target supports it.
1398 Two new YAZ client commands: . (dot, which sources a script of YAZ
1399 client commands), and ! (to execute shell command.). Implemented
1402 Working on Debian packages.
1404 --- 1.8.3 2001/11/19
1406 YAZ client enables named result sets only if target supports it.
1408 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1410 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1411 with key="host" to get same result.
1413 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1414 Function Z3950_resultset_record(s) returns references to records
1415 "owned" by resultset. To become owner use Z3950_record_clone.
1417 Function z_ext_record handles Extended Services. Thanks to
1420 --- 1.8.2 2001/11/12
1422 CCL Parser fix: ignore token comma when dealing with and-lists.
1424 Documentation updates for COMSTACK.
1426 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1427 Changed prototype Z3950_records. For some functions, int parameters
1428 were changed to size_t.
1430 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1433 New MARC decode/display function, marc_display_exl, which properly rejects
1434 non-ISO2709 records. YAZ client uses it.
1436 --- 1.8.1 2001/10/29
1438 Fix bug: local attribute set wasn't set correctly in PQF strings.
1442 * Old Z39.50 codecs no longer supported.
1444 Added ZOOM C binding. See http://zoom.z3950.org/
1446 Renamed states for COMSTACKs to avoid confusion with events.
1448 Implemented cs_look and proper cs_rcvconnect.
1450 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1452 Configure detects POSIX threads on OpenBSD.
1454 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1455 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1457 When error is returned from present handler, non-surrogate diagnostic
1458 is returned in present response (and fetch handler is no longer called).
1460 * Minor adjustments to pquery parser (PQF). Token characters may be
1461 escaped by using backslash (C-style).
1463 PQF parser allows string attribute values to be specified. For @attr,
1464 non-numeric characters after the equal-sign are treated as strings
1465 (e.g. @attr 9=title).
1467 CCL trunction character may be defined (@truncation in file)
1469 * function zget_ExtendedServicesRequest sets waitAction to
1470 waitIfPossible (was wait).
1472 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1475 CCL operator names may be set in field definition files (CCL_bibset).
1476 See ccl/bib1 for an example.
1478 Fixes in ASN.1 compiler for C++ compatibility.
1480 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1481 and "op_or" to avoid conflict with C++.
1483 Fixed problem with GNU readline detection on Redhat 7.0.
1485 Added step-size for Scan backend handler.
1487 Fixed bug that made the frontend server crash when no attribute
1488 set was specified for scan.
1490 Front-end server automatically switches to original working directory
1491 when installed as an NT service. Previously -w had to be specified to
1494 Added extended attributes for retrieval module (data1), so that data1
1495 records carry d1_readXML/SGML attributes. d1_read also supports
1496 null-data rules ( <tag/>)
1498 On UNIX when POSIX threads are available, a separate library libyazthread
1499 is created. Programmers should link with that library and the yaz library
1500 when using threads. The reason for the split was that some applications
1501 on Linux, such as Apache, doesn't work well when using shared objects that
1504 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1505 (or any frontend server) in SSL mode by specifying ssl: followed by
1506 address. Only tested on UNIX.
1508 Added feature for CCL module. Virtual structure s=al or s=ol generates
1509 and-list and or-list respectively instead of phrase search.
1513 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1514 log_mask_str. This was done to avoid name conflicts with other libraries
1515 (such as other PHP extensions).
1517 Added raw OID member for preferred record syntax (request_format_raw)
1518 and returned record syntax (output_format_raw) for backend fetch method.
1520 Config file yaz-config now accepts options so that it returns specific
1521 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1523 Shared library support for UNIX using GNU libtool.
1525 * Modified backend interface. Request/Response struct's replaced by
1526 one read/write C struct. For example bend_fetchrequest and
1527 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1528 Every handler - even search has to be registered in bend_init
1529 handler. This means that the YAZ library no longer refers to
1530 external functions and it makes it possible to make the whole
1531 thing a single DLL/SO.
1533 Added Segment handler for backend server.
1535 Added Zmbol/Zebra administrative functions to YAZ client.
1537 Threaded frontend server on UNIX (when POSIX Threads are available).
1538 Starting the server with option -T enables multi-threading.
1542 Added configure option --enable-comp/disable-comp to control use
1543 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1544 located in sub directory asn.
1546 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1547 in ${exec_prefix}/bin along with the other programs yaz-client and
1550 GNU automake used to maintain makefiles.
1552 Added several OID's.
1554 Changed retrieval module so that we can load records with no abstract
1555 syntax defined. Tagpaths in these records are fully composed of string
1558 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1562 On UNIX, the generated makefile now supports a proper 'make install'.
1563 The prefix can be set via GNU configure to set the install location
1564 (default is /usr/local).
1566 * YAZ programs client and ztest were renamed to yaz-client and
1567 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1568 locations, such as /usr/bin,/usr/local/bin,etc.
1570 * YAZ Header files were moved from include to include/yaz. YAZ Header
1571 files are referred to as include <yaz/log.h> rather than <log.h>.
1572 The YAZ include path (-I ..) is therefore the same as before. Programmers
1573 should update their #include statements or use -Ipath/include/yaz
1574 instead. The main motivation for doing this change is that YAZ header files
1575 can be installed in "standard" locations /usr/include,/usr/local/include
1576 without introducing conflicts, since ALL YAZ header files are stored
1577 in subdirectory yaz (under /usr/include for example).
1579 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1580 rather than project/workspace files. We switched because project files
1581 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1584 Changed name of logging function, logf, to yaz_log, to prevent name
1585 clash with some math-log functions. The YAZ header log.h defines logf
1586 to yaz_log (#define) so there should be no incompatibilities by this
1589 Added bend_start/bend_stop handlers for server. These handler are
1590 called on start/stop of server. For windows they are called whenever
1591 a service is started/stopped.
1593 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1594 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1595 in util/yc.tcl. The auto-generated C code structures are, in a few
1596 cases, incompatible with the old decoders. There are differences in the
1597 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1598 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1599 The preprocessor variable ASN_COMPILED is defined when the compiled
1600 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1601 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1602 wish to use the old encoders/decoders you can specify --disable-yc
1605 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1606 version so that it supports both new - and old version of DB Update
1608 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1609 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1610 change. The name parameter can be set to 0 in which no name is specified
1611 for the construction. The macros odr_implicit and odr_explicit sets name
1612 parameter to zero for the construction involved. New macros
1613 odr_implicit_tag and odr_explicit_tag are similar to the others,
1614 except that a name parameter is added. For programmers' that don't use
1615 ODR they probably only need to change the call to z_APDU and z_External.
1617 Added access control facility by interfacing the TCP wrapper library.
1618 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1619 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1620 name of the daemon and enables the access control as specified in
1621 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1623 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1624 den Dool <H.M.vdnDool@kub.nl>.
1626 Added reference ID parameter to most functions in server API - refer
1627 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1629 Changed name of ccl library to libccl.a (was ccl.a).
1631 Fixed bug in decoder for Explain (Category TargetInfo).
1633 Added support for GNU readline in client. Thanks to Jacob Poulsen
1634 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1636 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1637 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1638 IMPLEMENTATION! This change was made to the development version before
1639 the ZIG decided to retract the amendment. If any users MUST be
1640 compatible with the original Update definition, PLEASE CONTACT US, and
1641 we will include a separate definition corresponding to the old Update
1642 ES. Note that because of the change to the ASN.1 of the
1643 TaskPackageRecordStructure we cannot define a single structure that
1644 will support both versions.
1646 * Added const modifier to buffer parameter for some ODR/BER encoding
1647 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1648 completeWAIS, odr_dumpBER.
1650 Fixed bug in client.c which caused a crash when a scanResponse didn't
1651 contain positionOfTerm.
1653 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1654 * will cause an error in a client if a non-YAZ target sends both a
1655 * list of Scan entries and non-surrogate diagnostics.
1657 Retrieval module enhancements. Tag sets may be typed in the reference
1658 to it. From the .abs-file the "tagset" directive takes a third optional
1659 integer type for the tag set referenced. From a .tag-file the "include"
1660 directive takes a third optional type as well. The old "type" directive
1661 in the tag set itself is still recognized but acts as the default type
1664 Backend interface change. Individual Scan terms returned from bend_scan
1665 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1666 in include/backend.h.
1668 Retrieval module enhancements. Multiple tag sets and attribute sets may
1669 be specified in abstract syntax specs. Revised the error/warning for
1670 logging messages reported by the retrieval module when reading the
1673 Object Identifier system (oid_..) changed. The API is backwards
1674 compatible but the oid-routines now allocates new OID's when needed.
1675 Raw OID's may be specified in oid_getvalbyname.
1677 YAZ now uses GNU configure to generate Makefile(s).
1679 * Minor changes in some of the member names of DeleteResultSetRequest and
1680 DeleteResultSetResponse. See include/proto.h.
1682 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1683 and added member 'languages' in TargetInfo (which was missing).
1685 Changed the way attribute sets are handled in the retrieval
1686 module. These are now cached, just like the abstract syntaxes
1689 Changed YAZ so that it links with compiled ASN.1.
1691 Added Explain-schema definitions and mapping routines. The following
1692 Explain categories have been implemented: AttributeDetails,
1693 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1695 Fixed minor bug in Windows version of Server Library.
1697 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1699 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1701 Added EXTERNAL: UNIverse Resource Report (non-standard).
1703 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1704 ENUMERATED and SET OF.
1706 * Added 'const' to some of the char pointer arguments for the
1707 functions, data1_read_node, data1_getelementbytagname,
1708 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1711 Fixed bug in data1_insert_taggeddata - the last_child member of
1712 parent wasn't initialised.
1714 * Changed data1_read_record and data1_read_node so that the supplied
1715 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1716 doesn't refer to any parts of the "SGML"-buffer.
1718 Fixed bug in server library (Windows version of statserv_remove).
1720 * Changed code so that it compiles as C++. The type definition
1721 of Odr_fun which is a member of Odr_arm was changed. The result is,
1722 that an explicit typecast is needed for the fun pointer when
1723 using Odr_arm - as in:
1724 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1726 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1728 Implemented the new structured date and time definition as approved
1729 by the ZIG. Added schemaId element to the specificTag in Espec-1
1730 (also approved at the last ZIG). Thanks to RVDM.
1732 Added some Object identifiers (RVDM).
1734 Changed the Update Extended Service (RVDM).
1736 Added command "refid" to client which specifies referenceId for
1737 the following requests.
1739 Implemented extended service handling for server. See ztest.c
1740 for an example as well as backend.h. New handlers are registerd
1741 in the Init handler.
1743 * Changed interface for sort in server.
1745 Added new members to statserv_options_block. It allows a server
1746 to read options from another source than just the command line. Thanks
1747 to Charles Woodfield.
1749 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1750 renamed to zboolean. Some C++ compilers complained about the name.
1752 Minor changes to gils.abs. Added index 's' (sort) on title
1753 and date/time-last-modified.
1755 --- 1.4pl2 1998/1/30
1757 Fixed bug in server library regarding inetd mode (-i). This bug
1758 was introduced by release 1.4.
1760 --- 1.4pl1 1998/1/29
1762 Added sort facility in client and backend server interface.
1764 Fixed problem with dependencies in Makefile(s).
1766 Fixed bugs for encoders/decoders of extended services and
1769 Implemented sub-tree feature for schemas. Sub-trees are
1770 referenced in *.abs-files. See explain.abs for an example
1771 of the use of this feature.
1773 Modified bib1.att; local attributes for ANY didn't include
1774 ANY itself (only affects use of the retrieval module).
1776 Fixed bug in plain SGML reader in function data1_read_node:
1777 tags with prefix "var" was incorrectly interpreted as variants.
1779 Added feature "sub-schemas" to enable references to - and definitions
1780 of - group of elements.
1782 * Removed member parent from type data1_element (in data1.h).
1784 Implemented function odr_nullval() that returns the value of
1787 * Removed member num_children from data1_node (in data1.h).
1789 Made NT service interface part of the server library. The
1790 function statserv_main uses the NT service when required and
1791 calls the statserv_start / statserv_close routines.
1793 Routine zget_SearchRequest and zget_PresentRequest fills
1794 resultSetName/Id member with "default" instead of "Default".
1796 Fixed memory leak in server. Request queue member wasn't freed.
1798 Fixed nmem_exit so that memory is freed.
1802 Revised the CCL parser utility to be thread safe.
1804 Added function, oid_ent_to_oid, to replace the function
1805 oid_getoidbyent, which is not thread safe.
1807 * Added nmem_init and nmem_exit to initialize and release
1808 NMEM resources. Function nmem_init should be called once in the
1809 initial thread before NMEM/ODR is used. statserv.c and client.c
1810 have been changed accordingly. The change was necessary to make
1811 NMEM thread safe. The NMEM memory pool is shared amongst threads
1812 in a process. Unix-based applications will still work fine without
1815 Added NT Services interface for the the Z39.50 (statserv) Server.
1816 Refer to the ztest.c source on the usage.
1818 Windows 95/NT port using MSVC5.0. Project files are included in the
1821 * Defined new 'global' handle for the retrieval (data1) system. The
1822 new handled, data1_handle, describes the state of the data1 system.
1823 This handle is passed as first argument to virtually all
1824 data1 related routines. The functions data1_create and data1_destroy
1825 creates and destroys a data1 handle respectively.
1827 Added ODR encode stream member to all backend request structures
1828 init, search, scan etc. This stream should be used to allocate all
1829 memory used for the response when thread safe operation is needed.
1831 Changed the comstack utility, cs_addstr, to be thread safe. The
1832 returned hostname string returned by the function is now part the
1835 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1836 function. The cs_straddr takes a COMSTACK handle as argument, so this
1837 function must be used after cs_create and before bind/connect.
1838 This function is thread safe.
1840 Moved test server to 'ztest' directory - generic server code still
1841 in 'server' directory.
1843 Made prefix query (pquery.c) utility thread safe.
1845 Added new function modifier YAZ_EXPORT to 'export' public DLL
1846 functions when using windows (see include/yconfig.h).
1848 Added definitions to the OID database (util/oid.c) (RVDM).
1850 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1852 Added call to ccl_rpn_delete in client program.
1854 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1855 release of RPN structure.
1857 Added support for C++, headers uses extern "C" for public definitions.
1858 With input from RVDM.
1860 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1861 Thanks to Ronald van der Meer (RVDM).
1863 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1865 Added support for private extensions to the OID database
1866 (oid_setprivateoids()). Thanks to RVDM.
1868 Added optional, physical ANY (key replication)
1870 Fixed null-reference problem in GRS-1 output filter.
1872 Proximity operator added to Prefix Query Format (PQF).
1874 In test client command "base" accepts multiple databases.
1876 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1880 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1882 Smallish bug-fixes in the new encoders/decoders (explain).
1884 Bug fixed in DeleteRequest.
1886 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1888 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1890 Added SOIF syntax (using private OID for now) to retrieval module and client.
1892 Added Update extended service.
1894 Added SearchResult-1 additional info structure.
1896 Added optional CCL (ISO8777) interpreter as separate module. Available
1899 --- 1.2 1996/6/10 (1st anniversary release)
1901 Added Summary record syntax. Lightly tested.
1903 Added OPAC record syntax. Untested.
1905 Added ResourceReport service encoders/decoders. Untested.
1907 Fixed bug in z_Unit - wrong tagging on unitSystem.
1909 Fixed bug in the DiagRecs decoder.
1911 Added options for max PDU size and session timeout to frontend-server.
1913 Added documentation of query-language parsers and other supporting utilities.
1915 [frontend-server] Added Attribute set to the bend_scanrequest API.
1917 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1918 surrogate diagnostics were generated.
1920 [retrieval] Allow multiple local values for attribute.
1922 [retrieval] Allow multiple attributes per element in .abs files. index type.
1924 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1926 --- 1.1pl2 1996/4/10
1928 Minor changes, mostly specific to Zebra's requirements (retrieval)
1932 Repaired bug in frontend server when running multiple listening
1933 endpoints in dynamic mode.
1935 z_External() now won't break if a known, ASN.1 value comes encapsulated
1936 in an octet-string. The value will pass through unmodified in an Odr_oct.
1938 Added a bit of code to the demo client to decode & display
1939 ASN.1-structured records represented in the octet-aligned branch of
1940 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1942 Added z_ext_getentbyref() to the ASN module. Doc updated.
1944 * Completed the SCAN definition in the ASN module. This may break SCAN
1945 code based on older YAZ-versions at compile-time. The fix is easy -
1948 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1949 under the SCAN definition. Remember to initialize this, server-people.
1951 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1952 that this does not extend to ODR and ASN.
1954 Comstack allows insertion of established socket (primarily for
1955 inetd-operation of servers). Doc updated.
1957 Front-end server can now start from the inetd in TCP mode. Doc
1960 --- 1.0pl4 1996/1/24
1964 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1965 the rank and record number.
1967 Adjustments to the frontend server.
1969 Fixed diagnostic BER dumper. It ignored the file argument.
1973 Various changes to retrieval module.
1975 Changed the union discriminators of the protocol files from enums to
1976 ints paired with #defines.
1978 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1981 *Changed operator in the RPN structure to 'roperator', again to avoid a
1984 Fixed problems in Explain decoders/encoders.
1986 --- 1.0pl2 1995/12/6
1988 Memory bug in log module fixed.
1990 --- 1.0pl1 1995/12/5
1992 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1994 Bug in Explain DatabaseInfo module fixed.
1996 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2000 The shift to v1.0 signals that we now consider the *core* functionality
2001 of YAZ reasonably stable (the core being more or less equivalent to
2002 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2003 tested (Explain not at all - though that will happen soonish).
2005 Minor changes to code to support Windows port.
2007 Various minor changes after we're getting to use GRS-1 & co. more.
2009 Added Espec-1 format.
2011 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2012 of the protocol and it cannot be selected when encoding (maps into 'string'
2013 when decoding). Needed to talk to some servers.
2015 Demo client can request simple element set names.
2017 Added Diagnostic Format encoders/decoders.
2019 Added simple Close handling to frontend server (no hooks for resource
2020 reporting yet), and demonstration client.
2022 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2024 --- 1.0b3 1995/08/24
2026 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2027 handled incorrectly when records were requested in the searchResponse. This
2028 will only affect you if you use the frontend-server.
2030 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2031 Test-client will ask for and print GRS1. Ztest will return dummy records
2034 Added Explain encoders/decoders to the service-level API. Untested.
2036 Added Extended Services: Item Order encoders and decoders to the Service-
2037 level API. Untested. We could use a recent copy of the pertinent bits
2038 of the ILL protocol to add those bits.
2040 Added diagnostic format 1 encoders/decoders to the service-level API.
2043 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2044 odr_cons.c, which causes a more correct output.
2046 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2047 was always set to 0 when no records were requested in the searchRequest.
2049 * Added better external-handling. This shouldn't harm old code that
2050 *encodes* externals. It can break code that looks for a
2051 'single-ASN1-type' representation, since those types that are known
2052 are now decoded immediately. Look at the SUTRS sample code in
2053 seshigh.c and client.c. Documentation updated.
2055 Handling of structured records in bend_fetchresponse. Length -1 marks
2056 structured record, type is deduced from format field.
2058 --- 1.0b2 1995/06/27
2059 Fairly quick maintenance release to add SUTRS support.
2061 Fixed handling of SUTRS records in the demonstration client.
2063 * Added format field to the bend_fetchrequest and bend_fetchresponce
2064 structures of the backend API (frontend server). When the record is
2065 returned, the value of the format field is mapped to an OID. The
2066 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2067 of the record. The special value VAL_NONE in the bend_request means
2068 that no specific format was requested by the client. Documentation
2069 updated accordingly. Test server (ztest) will return a fixed dummy
2070 SUTRS record if your client requests SUTRS.
2072 Documentation updated accordingly.
2074 You can now set external libraries and RANLIB support in the top-level
2078 First public release.
