1 Fix to ZOOM-C so that transparent reconnection is properly handled on
2 connections that are in asynchronous mode.
4 Added character conversion support for "advancegreek"; based on patch from
9 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
10 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
11 fd_set structure used as a bitmask for the FDs to be selected on.
13 Using ACX_PTHREAD macro to check for POSIX threads.
15 Fixed have-vsnprintf check.
19 Fixes for configure on BSD. Bug #900.
21 Added snprintf/vsnprintf wrappers for systems that don't have
22 limits (heavens forbid).
24 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
25 created before all previous tasks were completed and removed from the
26 task queue, the new task could be removed by a mistake.
28 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
30 Implemented pass-through CQL-to-PQF conversions. Bug #861.
32 Fixed bug #832: Problem with MARC/charset in yaz-client.
34 Fixed bug #668: save command line history for yaz-client.
36 Fixed bug #830: pkg-config support.
40 Extended ZOOM result set options with two options that may be read by
41 a client: resultSetStatus and presentStatus with values as specified for
43 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
45 Fixed bug #827: Using SSL fails on Debian etch.
47 Fixed bug #826: Weird looking chars for set of MARC records.
49 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
50 that is treated as an ItemOrder with itemRequest being an XML document
51 external. The value of "doc" is the content.
53 Extended the GFS search facility. New member of bend_search_rr
54 'estimated_hit_count' signals that hits is known to be an estmate
55 (higher or lower than real hit count). New member 'partial_resultset'
56 signals that the search was partial (hit count is lower or equal than
57 real hit count). For Z39.50, the information is stored in resultSetStatus
58 member of SearchResponse APDU. For SRU, the information is signalled
59 via SRU diagnostic 59: "Result set created with valid partial results
62 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
66 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
68 Added ZOOM_connection_peek_event.
70 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
71 the following new functions:
72 ZOOM_event_nonblock, ZOOM_connection_process,
73 ZOOM_connection_get_{socket,mask,timeout},
74 ZOOM_connection_fire_event_{timeout,socket}.
75 The existing blocking event handler, ZOOM_event, is a wrapper for the
76 + blocking ZOOM_event_sys_{poll,select}.
78 Implemented function ccl_xml_config which parses XML version of CCL
79 configuration (bug #798).
81 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
83 Added timings utility (yaz/timing.h)
87 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
90 Fixed bug #779: Rotation of apdu.log fails.
92 Fixed for character set conversions:
93 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
94 Honor G1 set in MARC-8 decoding.
98 Fixed bug #775: char conversion does not handle Alternative UTF-8
101 Implemented function yaz_marc_read_line which parses MARC line format
102 records. There is a wealth of formats out there. So far, this function
103 reads line records produced by yaz_marc_write_line.
105 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
106 more generic and easier to remember(!) options: -i format and -o format
107 which specifies input format and output format respectively - where
108 format is one of "marc", "marcxml", "line", "marcxchange".
110 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
111 does not print anything except warnings for records.
113 For yaz-marcdump, added support for MARC split into files (-s) with a given
116 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
117 spec, at http://www.loc.gov/standards/sru/record-update/
118 This has changed the binary layout of the following structs:
119 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
120 bend_update_rr . Patch by Ko van der Sloot.
122 Added GFS utility function bend_assoc_is_alive which returns 1 if
123 association is still alive (client is connected); 0 otherwise (client
124 closed connection). This allows busy servers to stop working for
127 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
128 been a separate piece of software. This version of ziffy has been modified
129 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
131 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
133 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
134 Client code may now interrogate options such as "init_opt_sort" to
135 find out whether the server claims to support various options.
137 --- 2.1.40 2006/11/27
139 Added utilities yaz_{set,get}_esn to set/get element set name from
142 Removed the build of libyazthread.la. The libyaz.so is the threaded version
143 of YAZ and has been so since YAZ 2.1.10.
145 Implemented ZOOM_record_error which returns error information for
146 record (surrogate diagnostic).
148 --- 2.1.38 2006/10/31
150 Updates for SRU Update by Ko van der Sloot:
151 1. Changed name from "operation" to "action"
152 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
153 versions in the code, marked as 'backward compatible'.
154 3. Added diagnostics for SRU Update.
156 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
158 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
160 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
162 For GFS, fixed problem with SRU diagnostic 'First record position out of
163 range' being issued for 0 hits.
165 zoomtst10 part of Windows Build.
167 --- 2.1.36 2006/10/13
169 Implemented yaz_filepath_comp which splits a path into file path
170 components (required by Zebra 2.0.3+).
172 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
173 BSD inspired license until now so this should not have any real impact on
174 anybody. See http://www.opensource.org/licenses/bsd-license.php
176 Fixed bug #687: Missing log lines.
178 Fixed bug #678: CQL to PQF translation does not preserve double-quote
181 Fixed bug #689: SRU diagnostics to be added.
183 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
184 whether a connection is idle (no more work do do).
186 --- 2.1.34 2006/10/04
188 Change type of optval from long to int for invocation of setsockopt with
189 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
191 Added support for specifying the max log file size for the Generic
192 Frontend Server. The size is given with option -r.
194 --- 2.1.32 2006/09/21
196 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
198 --- 2.1.30 2006/09/17
200 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
203 Fixed bug in Generic Frontend Server that could cause a server to stop
204 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
206 For the generic frontend server, the maximum record size is used as maximum
207 size of incoming packages (SRU + Z39.50). The value until was previously
208 only used in Z39.50 Init negotiation and, later, in a session controlled
209 sizes of records returned. This is controlled using -k option. It can be
210 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
212 --- 2.1.28 2006/09/04
214 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
217 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
219 New option for yaz-marcdump -lpos=value which allows setting a portion
220 of MARC header to a certain value.
222 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
224 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
225 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
227 --- 2.1.26 2006/08/15
229 Fixed problem with SRU mode type (soap, get, post) for yaz-client
232 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
234 --- 2.1.24 2006/08/08
236 Fixed MARC ISO2709 encoding routines to deal with character set
239 Minor changes to GFS logging. Database included in search request log
242 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
243 cached/multiple records.
245 Shared libraries are built by default on Unix+configure.
247 Changed cql2pqf transformation to use a different evaluation order. The
248 new order is: always, relation, structure, position, truncation, index
249 and relationModifier. Old order was: always, relation, relationModifier,
250 structure, index, position, truncation. Note that the the latter ones
251 override former ones for identical attributes.. The new scheme means that
252 it is possible to override any existing attribute with a relationModifier.
253 And also that it is possible to override everything for the index rule
254 (except the ones listed in relationModifier). No order is perfect but this
255 one, we believe, covers more real cases.. The "always" should have been
256 called "default", since the attributes there can be overridden with all
259 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
260 compilation phase, but also for yaz-config --cflags output. This allows
261 us to have public headers with Libxml2 stuff in them . It should also,
262 eventually, make Libxml2 checks redundant in packages using YAZ, such
265 --- 2.1.22 2006/06/15
267 Changed SRU update structure bend_update_rr so that SRU diagnostics are
268 stored in uri, message and details.. Previously diagnostics were stored
269 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
270 compatibility.. but he's probably the only one affected, so.
272 Added support for CCL, compiled on the client side, in ZOOM-C. This
273 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
274 input; the resulting query objects can be used for for searching with
275 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
277 YAZ' configure searches for OpenSSL by default.
279 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
280 SL_CTX_use_certificate_file. See
281 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
282 for more info. Thanks to Ko van der Sloot.
284 --- 2.1.20 2006/06/02
286 Bug #600: SRU GET, POST support for yaz-client. Introduced
287 command 'sru' which selects method SOAP/GET/POST.
289 Allow missingValueAction to be specified for the sortspec string -
290 function yaz_sort_spec. By default, the missing value action is null.
291 Use ! to specify "abort". Use = followed by stringvalue to specify default
294 Ensured that Present-handler (if defined) is called in GFS before any call to
295 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
296 searchRetrieve requests.
298 Documentation for YAZ is now based on the Docbook XML/XSLT using
299 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
300 is no longer depending on jade/openjade or docbook-to-man scripts.
301 PDF is no longer part of the distribution - but can optionally be
302 made using DSSSL/jadetex or FOP.
304 Added retrieval handling support in Generic Frontend Server to support
305 conversion between MARC/XML as well as XSLTtransforms. See
306 etc/yazgfs.xml for an example.
308 Added Authentication support to Generic Frontend Server in SRU
309 mode. Authentication using HTTP Basic is supported, as is the use
310 of 'x-username' and 'x-password' parameters in the request itself.
312 Added support for a new character set MARC8s identical to MARC8 except
313 that it converts combined characters to single Unicode characters in the
314 Latin-1 range (when possible).
316 --- 2.1.18 2006/04/24
318 ASN.1 compiler 0.4: generates brief Doxygen file header for
319 generated .h/.c files.
321 Utility yaz_iconv now supports conversion to MARC-8.
323 New facilities for the MARC module. The reading - and writing of
324 content are separate methods for the yaz_marc_t handle. The following
325 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
326 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
327 format). Write functions have prefix yaz_marc_write_.. The existing
328 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
329 available. Removed support for OAI-MARC and simplexml (not the
330 simplexml from PHP5).
332 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
333 to be returned for this connection.
335 --- 2.1.16 2006/03/31
337 Allow multiple languages and charsets to be specified with
338 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
339 negcharset iso-8859-1,utf-8
341 Translation of proximity nodes from CQL into PQF now works.
343 Moved to automake 1.8, 1.9.
345 Added function yaz_log_set_handler which allows a log handler to be
346 installed. This handler will be called for all log messages. Output
347 to file is also produced; but that can be disabled by passing NULL
348 fname to yaz_log_init_file.
350 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
352 For SRW (including GFS), accept application/soap+xml as content-type
355 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
356 produces NO stylesheet reference even if a default stylesheet is specified
359 --- 2.1.14 2006/03/14
361 Updated Windows package to include yazd.dll + yazd.lib for the
362 Development component.
364 If the environment variable YAZ_LOG is set, then it is used as a
365 string indicating the default level of logging to use if not
366 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
367 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
368 used as before. So, for example, to omit warnings from YAZ logging,
371 cql_transform() now map structure and other attributes before indexes,
372 so that index-specific structures and other attributes can override
373 defaults. So now a combination of mapping specifications such as:
375 index.dc.date = 1=date-modified 4=5
376 does the right thing.
378 cql_transform() now also respects the "always" mapping specification,
379 which establishes an initial set of attributes to be used for all
380 terms except where overridden by more specific attributes associated
381 with the index, relation or modifier.
383 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
384 which mode to use; one of "post", "get" or "soap" (SRW, default).
386 Fixes for yaz_iconv routines: changed trie-based character set conversions
387 to use only non-negative values for bit fields due to Sun's C compiler not
388 supporting negative values.
390 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
391 sequences where not read correctly. Fix by Rustam Usmanov.
393 Updated win/makefile to use options, settings which makes things
394 compile with VS C 2005.
396 --- 2.1.12 2006/02/01
398 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
400 In ZOOM socket code, use select instead of poll on MacOSX.
402 ZOOM-C now support client-side compilation of CQL into RPN that is
403 sent to the server, enabling CQL to be used against all Z39.50
404 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
405 ZOOM_query object, and submit it using ZOOM_connection_search().
406 The CQL-to-RPN translation uses a configuration file, the name of
407 which must be specified in the Connection's "cqlfile" option.
409 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
410 function, which takes as its start-term parameter a ZOOM_query object
411 (which may have had either CQL or RPN set into it).
414 --- 2.1.10 2005/11/29
416 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
417 GFS to support this as well. Backend handler, bend_srw_update, does the
418 update work. Code contributed by Ko van der Sloot.
420 Allow retrieval of Search Result-1 information in ZOOM by the use of
421 options that are attached to a result set. ZOOM documentation updated
424 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
425 UTF-8 conversion. Patch by Raj Patel.
427 Added option -m to GFS to control formatting of timestamps in log file.
429 Added 'exit' as synonym for 'quit' in yaz-client
431 Added support for specifying SRW resultSetId + resultSetIdleTime in a
432 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
433 for the new members. Patch by Ko van der Sloot.
435 Added support for SRU POST. It is supported for content-type
436 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
438 Do not build the separate Multi-threaded (MT) library libyazthread.la.
439 Instead make the library libyaz.la multi-threaded. Threading as a whole
440 can still be disabled by configure option --disable-threads. Previosly,
441 with older GLIBCs there were problems with MT libs under Apache. This
442 has now been fixed a long time ago.
444 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
447 CQL module modified to be case insensitive for relations/indexes/operations.
449 Fixed bug in CQL transform code: incorrect value relationModifieder
452 Added 'show all' command for yaz-client which retrieves all results
455 Added new yaz-client, xmles, which takes a (private) OID and
456 a document to be sent as an extended service request.
458 Describe new yaz-client commands wait_response and set_auto_wait.
460 Increase TCP/IP listener backlog from 3 (which I am guessing was
461 copied from the SunOS manual entry way back when) so SOMAXCONN, so
462 that the socket will queue as many incoming connections as it's able
463 to handle ongoing connections. In other words, it will never now
464 refuse a connection that it would be able to handle merely because
465 it's not got around to accepting() enough of the pending connections
466 yet. This is the behaviour anyway under Linux, where the listen()
467 argument is ignored; but not under BSD and on systems such as
468 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
469 YAZ-based servers should now be uniform across operating systems in
472 yaz-marcdump uses 64-bit file access on some systems. This is enabled
473 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
474 This allows yaz-marcdump to read large MARC batches (>2 GB).
476 Modified all YAZ source files - except the source which is auto-generated
477 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
480 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
481 corresponding to the existing *_setl() function. These allow option
482 values containing arbitrary valuues.
484 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
485 ZOOM_resultset_sort() in new applications. Its behaviour is identical
486 except that it returns an indicator of whether or not the sort
487 criterion was accepted (0 for OK, -1 for invalid).
491 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
492 MARC output rather than returning "new" buffer.
494 yaz-client warns about unknown init options.
496 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
500 Added support for SRW sort in Generic Frontend Server. Patch
501 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
502 sortKeys - or NULL if none is provided.
504 Fixed bug #307: It was impossible to specify indefinite/no timeout
505 for ZOOM_event. Special timeout value -1 now means indefinite timeout
508 Added support for multiple languages and charsets to be specified in
509 ZOOM. Each charset/language is separated by a blank. If negotiation is
510 in effect in init-response, Option
511 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
512 Code based on patch by Vasiliy Osadchuk.
514 Fixed bug #306: infinite recursion that occurred when calling
515 yaz_log_level_init as the first call (before other log level or
518 Fixed bug in scan handling in front end server: if preferred-Position-In-
519 Response was non-present, a NULL pointer referece was performed.
523 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
524 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
525 now defined for all those error codes. So instead of putting 109 in
526 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
527 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
529 Modified the yaz-marcdump utility to skip garbage bytes between MARC
532 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
534 Program yaz-client now exits and produces an error message if multiple
535 Z39.50 servers are specified on the command line (none or one allowed
538 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
543 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
545 Fixed bug #272: Preserve spacing for CCL terms.
549 Added support for virtual hosts and multiple backend servers for
550 the YAZ frontend server. The configution is XML based and
551 support specificition of CQL to RPN mappings and explain information.
552 See section "Virtual Hosts" in the YAZ manual.
554 Extended OPAC display utility. OPAC display utility renders
555 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
556 to supplement yaz_marc_decode_wrbuf.
558 Fixed a bug in MARC decoder that could caused it to crash for some
559 invalid MARC records. More diagnostics and warnings where added in
560 XML output (warnings, etc are stored in comments).
562 --- 2.0.34 2005/02/08
564 Fixes for UNIX domain sockets. Bug #261.
566 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
568 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
569 Added yaz_marc_subfield_str which defines subfield lead string which is
570 used in YAZ_MARC_LINE format. Default string is blank+$. Added
571 yaz_marc_endline_str which defines end of fields string used in
572 YAZ_MARC_LINE format. Default string is newline.
574 Experimental support for MarcXChange. This format can be produced
575 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
576 http://www.bs.dk/standards/MarcXchange.xsd
578 Added yaz-client commands scansize that sets maximum number of
579 entries to be returned by scan.
581 --- 2.0.32 2005/01/11
583 Added support for SRW scan in yaz-client and Generic Frontend Server.
585 * Added whereInList member to SRW Scan Term.
587 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
589 Fixed NMEM system to return aligned blocks on the smallest boundaries
590 that are suitably aligned for all possible types on the particular
591 architecture YAZ is being built for.
593 --- 2.0.30 2005/01/04
595 Fixed numerious warnings that was issued with newer versions of GCC.
597 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
598 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
601 Make YAZ Generic Frontend Server slightly faster.
603 Enhance (and reduce) logging for Generic Frontend Server.
605 Revert YAZ log system so that it flushes every write operation
606 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
608 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
609 instead of LOG_, due to name clash with syslog(3). LOG_ are still
610 present. New applications should define YAZ_USE_NEW_LOG=1 - this
611 will effectively disable old definitions.
613 --- 2.0.28 2004/11/09
615 Added yaz_log_time_format which specifies log format using
618 Added yaz_log_module_level which returns mask for a module. Value
619 is non-zero mask a if module is enabled; zero if disabled.
621 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
622 in include/yaz/cql.h.
624 Fixed bug #176: Dont throw diagnostics on empty SRU args.
626 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
628 Fixed bug #172: RPM builds does not enable SSL.
630 Doxyfile.in part of dist. Doxyfile generated by configure.
632 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
633 are given and the corresponding component does not exist.
635 Extend CCL documentation in YAZ reference. Describe r=r.
637 --- 2.0.26 2004/10/01
639 Fixed MARC->MARCXML conversion to properly deal with
640 fields, subfields, indicators having non-ASCII characters.
642 Fixed MARC->MARCXML conversion so that ASCII control characters
643 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
646 Added YAZ GFS support for conversion from Z39.50 surrogate
647 diagnostics to SRW surrogate diagnostics.
649 Bug fix: YAZ GFS did not return schema in explainResponse.
651 --- 2.0.25 2004/09/30
653 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
654 now converts recordSchema to elementSetName as well as schema URI.
656 Fixed bug in COMSTACK that prevented HTTP request packages from being
659 --- 2.0.24 2004/09/29
661 Added CCL facility r=r "range" which is similar to r=o "ordered" but
662 does not require white-space before and after the dash in a range, e.g.
663 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
666 Fixed a few AC_TRY_LINK configure tests that did not operate properly
667 due to new GCC removing "redundant" code.
669 Added yaz-client commands scanpos and scanstep that sets preferred
670 position and step-size for scan.
672 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
674 Added CCL utility ccl_qual_buf which parses one or more CCL
675 spec lines in a buffer.
677 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
678 of name and value - ignoring empty lines and comments.
680 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
682 Added odr_get_element_path which returns current element path for an
683 ODR handle. This utility is useful in error handling or user-defined
686 Added ODR_PRINT utility odr_set_stream which is is a more generic
687 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
688 to a write function and pointer to close function. The close function - if
689 non-NULL - will be called during odr_destroy.
691 Fixed bug in CCL parser where truncation char was not removed from
692 right side when truncation=both was in effect.
694 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
697 --- 2.0.23 2004/08/11
699 Fix buffer overrun in CQL parser when dealing with proximity (%).
701 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
702 to UTF-8/UCS conversion is now only based on codetables.xml.
704 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
706 --- 2.0.22 2004/08/06
708 Add support for more "commit changes" in ZOOM (uses Extended Services).
710 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
713 Yet another small fix for configure of SSL.
715 --- 2.0.21 2004/05/14
717 Fix SSL libs for configure when --with-openssl=DIR is given.
719 --- 2.0.20 2004/05/10
721 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
723 SSL comstack now uses yaz.pem certificate file on server side
724 by default. Certificate filename can be configured by calling
725 comstack function cs_set_ssl_certificate_file before cs_bind is used.
727 Fix bug regarding multiple calls to ZOOM_connection_connect.
729 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
731 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
732 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
734 ZOOM now allows inspection of X509 peer certificate for verification.
735 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
737 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
738 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
739 as "modular" but it simplifies things.
741 Added cs_get_peer_certificate to that returns peer X509 PEM.
743 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
744 NULL if SSL is unavailable.
746 Documentation about MARC decoding tools.
748 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
750 --- 2.0.19 2004/03/30
752 Rename CHANGELOG to NEWS to follow GNU style packing.
754 Fix bug with missing initialization of member in init_diagnostics.
755 This bug affects threaded version of GFS server.
757 --- 2.0.18 2004/03/20
759 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
762 Ensure zlib.dll is packed with Windows install.
764 --- 2.0.17 2004/03/17
766 Fix encoding of xsd:string to use text instead of CDATA.
768 Fix endless loop in CQL parser with unbalanced ".
770 Use a more compact way to store MARC-8 conversion tables.
772 --- 2.0.16 2004/03/16 Debian only
774 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
777 Update CQL parser to use new CQL 1.1 modifiers for booleans and
782 --- 2.0.15 2004/03/01
784 Another fix for decoding of XML packed records.
786 --- 2.0.14 2004/02/25
788 Fixes for Chunked encoding. White space not ignored after length spec.
790 Update NS and use default NS for SRW diagnostic elements.
792 --- 2.0.13 2004/02/23
794 Implement ZOOM_resultset_cache_reset which resets record cache.
796 Implement ZOOM_resultset_sort which sorts a result set.
798 Implement chunked HTTP transfer.
800 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
802 --- 2.0.12 2004/02/16
804 Added member 'schema' to bend_explain_rr structure so that backend
805 can specify explain record identifier. Defaults to Zeerex 2.0.
807 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
809 --- 2.0.11 2004/02/16
811 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
814 Added init command for yaz-client which sends "extra" init request.
816 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
817 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
819 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
821 Make ZOOM error code for "invalid query".
823 Fixed compilation for SSL which wasn't properly enabled for all platforms.
825 --- 2.0.10 2004/02/05
827 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
830 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
832 Added option -p <file> to make Generic Frontend Server to write PID file.
834 Added option -D to put Generic Frontend Server in background on its own.
836 Make ZOOM C recognize option "password". If unset, "pass" is used
837 (for backwards compatibility).
839 Fixed a bug in Generic Frontend Server that could make it crash if a
840 client sets characterSetNegotation bit, but didn't pass negotiation stuff
843 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
844 Must be issued before open, in order to be in effect.
846 --- 2.0.9-6 2004/01/12 Debian/Windows
848 Make the SRU server more picky WRT unknown params, etc.
850 Bug fix: ZOOM scan response didn't return displayTerm - when present.
852 New YAZ client command, options, that sets Z39.50 options.
854 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
855 options from a string of tokens (one token for each option bit).
857 Update SRW diagnostic code messages.
859 --- 2.0.9-5 2004/01/07 Debian/Windows
861 Handle user defined stylesheet for SRW/SRU.
863 --- 2.0.9-4 2004/01/06 Debian/Windows
865 Fix bug in decoding of Content-Length.
867 --- 2.0.9-3 2004/01/06 Debian/Windows
869 Fix a bug with decoding of XML packed records.
871 --- 2.0.9-2 2004/01/05 Debian only
873 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
875 Fix bug in SRW/SRU diagnostics decoding.
879 Fixed bug in Generic Frontend Server which could drop records exceeding
880 preferred message size. Reported and fixed by Irina Dijour.
882 Fixed calculation of package size for structured records in Generic
883 Frontend Server. Reported and fixed by Irina Dijour.
885 Fixed namespace for SRW/SRU diagnostics.
887 Fixed SEGV in yaz-client that occured for HTTP connection errors.
891 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
892 this version is incompatible with version 1.0 and older YAZ SRW/SRU
895 CQL changes to reflect recent changes to the specification:
896 * Documentation talks about context sets instead of index sets.
897 * Documentation talks about indexes instead of qualifiers.
898 * The CQL-to-PQF transformer's configuration file now uses
899 "index.set.name = <attributes>" instead of the old form
900 "qualifier.set.name = <attributes>". (Both forms are still
901 understood but the latter is deprecated.)
902 * CQL terms with no explicit index specified are now interpreted as
903 cql.serverChoice instead of srw.serverChoice (which of course
904 behaves exactly the same.)
908 MARC conversion can now generate ISO2709 output in another
909 character set. yaz-marcdump uses this facility if you invoke it
912 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
913 functions from there can be used from C++.
917 Frontend server now transfers memory from decoded packages to stream
920 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
921 references to show up.
923 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
924 the ZOOM Abstract API. The older names for the same options are still
925 also supported for the benefit of old applications.
927 ZOOM-C supports "implementationId" and "implementationVersion" options
928 to go along with "implementationName". These allow the user code to
929 specify identification strings to be sent to servers.
930 Add OID for the new ExtLite attribute set.
932 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
933 as requested/supplid by Ere Maijala <ere@atp.fi>
935 For generic frontend server, reverse the order of
936 "toolkit-supplied / application-supplied" strings sent as implementationId,
937 Name and Version. Also, remove the spaces around the slash. This brings
938 the GFS in line with the behaviour of ZOOM-C on the client side.
940 Add function ZOOM_scanset_display_term.
942 yaz-client shows scan displayTerm if present.
944 Utility yaz-iconv is now installed by default along with the man page
947 Extend configure check for OpenSSL to use pkg-config where available (such
950 Incorporate patch by Morten Bogeskov which allows a Unix file socket
951 server to specify uid/gid/mask for socket using the format
952 unix:[user=uid,][group=gid,][umask=mask,]file=path
953 If file= is omitted the existing format is assumed, e.g.
955 in which case the mask is 0666 (rw for everybody).
957 Major restructure of YAZ source. All source in libyaz is in src directory.
958 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
959 util (utility programs such as ASN.1 compiler, yaz-marcdump).
961 Added man page for utility yaz-marcdump (used to be called marcdump).
962 yaz-marcdump is installed by 'make install'.
964 Fixed a memory leak in Generic Frontend Server that occurred when decoding
965 of incoming package failed.
967 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
969 Change prototype of odr_perror: add const to message string.
971 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
973 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
974 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
975 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
976 DNS lookup. There should not be any compatibility problems with this
977 assuming that blocking=1 or 0 is used.
979 Fix bad reference in UNIX comstack in function cs_addrstr.
981 Fix for compilation on AIX.
983 The generic front-end server (server/seshigh.c) now supports returning
984 Init diagnostics to the client in User-information-field, in
985 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
990 Allow any CQL relation (not just all,any,exact,scr).
992 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
993 that features the same UI.
995 Implemented command update0 in YAZ client which is equivalent to
996 update but uses old of Ext Update ASN.1.
998 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
999 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1000 Previously no OID was used for this info.
1002 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1003 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1004 returns 'malformed search term' otherwise.
1006 SortResponse member resultCount now set to NULL in sort handler of
1009 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1012 Add three new utility functions for translating OIDs between various
1013 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1014 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1015 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1016 char *oid_to_dotstring(const int *oid, char *oidbuf);
1017 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1019 Reverted modifications for ES Update definition for z_IU0Update
1020 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1021 is back to YAZ 2.0.2.
1023 String value attributes for CCL parser.
1025 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1026 which their FirstSearch server returns in Init responses, sometimes
1027 carrying useful diagnostic information when Init fails. This has the
1028 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1029 "z39.50/oclcui.asn", where its definition is somewhat different from
1030 what OCLC document on their web-site, as required to interoperate with
1033 Support for anonymous authentication in yaz-client. Use the command
1036 * Fix the OID of the Index Data-local "admin" Extended Service from
1037 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1038 the 1000, which indicates a locally-defined OID, was a mistake.
1040 --- 2.0.3 2003/06/20
1042 Fix CCL directive @case handling so that it affects string match for
1043 both CCL keywords and qualifiers.
1045 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1046 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1047 Decoder has been updated with ASN.1 changes as listed in
1048 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1049 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1050 z_IUUpdate, remains unchanged.
1052 ZOOM_record_get may now return a record in a specific character set.
1053 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1054 "from" is the character set of record as returned by target. "to" is
1055 the character set to be returned. If omitted, "to" is UTF-8.
1057 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1059 New ODR utility, odr_getelement, which returns name of element for
1060 which encoding/decoding failed.
1062 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1063 in cases where a required element was omitted.
1065 Bug fix: some MARC8 sequences were not converted.
1067 New ZOOM option "step" which specifies number of records to be
1068 retrieved in one chunk. Used in conjunction with "start" and "count".
1070 SRW support for yaz-client. Use scheme http: to use it, e.g.
1073 yaz-client no longer does (un)intelligent character set conversions
1074 by default. Can be enabled with charset and marc_charset commands.
1076 xmalloc trace fix for 64-bit systems such as DEC alpha.
1078 Solaris 2.6 compile fix.
1080 New function, cql_strerror() translates SRW error codes, as returned
1081 by cql_transform_error(), into human-readable English strings. Used
1082 in yaz-client diagnostics when appropriate.
1084 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1085 converts it into a type-1 query which is sent to the server. This
1086 makes CQL available for use with all Z-servers, as opposed to the tiny
1087 minority that can handle CQL queries themselves.
1089 --- 2.0.2 2003/04/28
1091 New Debian package layout similar to the Redhat Package layout.
1093 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1094 and search result respectively.
1096 --- 2.0.1 2003/04/25
1098 Redhat package is now several packages: libyaz (runtime libraries),
1099 libyaz-devel (development and documentation, and yaz (utility programs).
1100 Package spec file by Morten Bøgeskov.
1102 New member 'schema' in struct bend_fetch_rr which the name of requested
1103 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1104 handler MAY set this to reflect the schema of the returned record.
1106 New member 'display_term' in struct scan_entry. GFS now sets member entries
1107 and allocates scan entries to be filled by user scan handler. In previous
1108 version, entries member was allocated by the scan handler. That still works,
1109 but the GFS will ignore member display_term - assuming it was NOT set by
1110 the handler. The fact that the GFS now allocates the entries both allows
1111 for new members and makes a scan handler easier to write.
1113 Fix CQL lex buffer overflow.
1115 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1116 SRU default recordPacking is string.
1118 SRU protocol support for frontend server.
1120 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1122 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1124 Added scan for the ZOOM shell (zoomsh).
1128 * String Identifers for Schemas (Amendment 5).
1129 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1130 Old definition for schema
1131 Odr_oid *schema; /* OPT */
1136 Z_InternationalString *uri;
1137 #define Z_Schema_oid 1
1138 #define Z_Schema_uri 2
1141 * resultCount parameter to Sort Response (Amendment 1).
1142 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1144 Support for SRW 1.0 over HTTP. This is an optional feature and
1145 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1148 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1149 on the same port. SRW SearchRetrieveRequests are mapped
1150 to bend_init,bend_search,bend_fetch,bend_close.
1152 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1154 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1155 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1157 ZOOM connections are SRW based if schem http is used for hostname
1158 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1159 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1161 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1162 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1163 distance=n, order=true/false, relation=le, prox unit=word. If
1164 n is omitted, distance 1 is used.
1166 Fixed problem with C compiler include path in wrong order.
1168 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1169 on Solaris. Patch from Ko van der Sloot.
1171 New MARC decode API. All new functions operate on a yaz_marc_t
1172 handle. The most important new functions are: yaz_marc_create,
1173 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1174 decode and destroy respectively. Decoder can produce formats
1175 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1176 include/yaz/marcdisp.h.
1178 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1179 to UTF-8, UCS-32, wchar_t or Latin-1.
1181 * Prototypes for yaz_iconv_-functions moved to separate header
1182 include/yaz/yaz-iconv.h.
1184 Make a few private functions 'static' in unix.c. This prevents
1185 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1187 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1188 are set when Init Response is received.
1190 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1191 but returns diagnostic set as well.
1193 New function yaz_strerror which is a portable wrapper for
1194 strerror/strerror_r/GetLastMessage.
1196 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1197 is returned for MARC. If type is "oai", then OAI MARC is returned.
1199 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1202 --- 1.9.2 2002/11/26
1204 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1206 Fix bad race conditions on SIGTERM and terminate gracefully in
1209 Move retrieval (data1) module to Zebra since nobody seems to be
1212 Add GRS-1 render for ZOOM using same format as yaz-client.
1214 --- 1.9.1 2002/10/05
1216 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1218 Fix broken ESpec handling in data1 module.
1220 SGML reader parses comments and makes them part of the data1 tree.
1222 Added several type casts so that YAZ compiles as C++ code.
1224 ZOOM didn't handle PDU encoding failures properly.
1226 Added more Bib-1 diagnostics (approved extensions).
1228 GNU configure: better check for iconv.
1230 More portable use of accept, getpeername. Check for socklen_t. Use
1231 int/size_t if socklen_t is not defined.
1235 PQF parser rejects bad queries - including those with extra
1236 characters in them. PQF parser used to silently ignore that.
1237 Cleaner API for PQF added, which allows you to get detailed
1238 error information for bad queries (see yaz/pquery.h).
1240 Fixed bug in ZOOM_record_get for type "database".
1242 Implemented mini iconv library supporting conversions between
1243 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1245 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1247 --- 1.8.9 2002/08/20
1249 Fixed ZOOM C record cache so that preferredRecordSyntax and
1250 elementSetName is used to check for already fetched records.
1252 --- 1.8.8 2002/08/02
1254 Added three members in bend_initrequest structure to facilitate
1255 character set negotiation.
1257 Fixed a bug in frontend server that could cause indefinite
1258 loops under rare conditions.
1260 Revised character set utilities (charneg.h) so that encoding
1261 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1263 For PQF, directive @term <type> sets term type for Scan/Search.
1264 Here <type> is general, string, numeric, null. The term type
1265 is inherited - just like @attr.
1267 New call odr_set_charset that sets character set conversion for
1268 international-strings on a ODR stream. Prototype is:
1269 int odr_set_charset(ODR o, const char *to, const char *from);
1270 The InternationalString is still represented as C string in YAZ
1271 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1272 won't). On the protocol level, you can use any encoding.
1274 Support for UNIX sockets in ZOOM.
1276 Solaris recv sometimes returns errno == ENOENT. It is treated as
1277 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1279 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1280 both client and server. Code by Morten Bøgeskov.
1282 --- 1.8.7 2002/05/22
1284 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1285 that they can be used directly from Visual Basic. You must recompile
1286 your windows APP if you're using ZOOM.
1288 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1289 Commands "lang" and "charset" sets language and character set respectively.
1290 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1291 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1293 Attributes from multiple CCL fields may be OR'ed rather than merged
1294 using directive "@field or". Fields are still merged by default -
1295 equivalent to "@field merge".
1297 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1300 Fixed bug in zget for parameter ExtendedServicesResponse.
1304 --- 1.8.6 2002/03/25
1306 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1308 Client displays USR.1:SearchResult-1 (hits per term).
1310 Additional Search Info for search in Generic Frontend Server.
1312 Fixed CCL parsing of "field=s".
1314 WIN32 installer - using the excellent NSIS software from nullsoft.
1316 Fixed CCL parsing of "field = - <number>".
1318 Added function yaz_marc_decode that decodes MARC for line mode
1319 display or XML (similar to that used by JZKit).
1321 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1322 Z39.50. But ISO/ILL was, however.
1324 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1325 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1328 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1330 --- 1.8.5 2002/02/03
1332 New YAZ client features: Command completion and new commands:
1333 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1334 Code provided by Jacob Poulsen.
1336 New call oid_trav, that visits all registered OIDs via callback.
1338 Function ZOOM_record_get now returns const char pointer rather than
1339 void pointer. It saves a lot of type casts.
1341 For YAZ client, command "auth" now allows you to set authentication
1342 in IdPass style. It is enabled when three tokens are given - order
1343 is user, group and password.
1345 Fix memory leaks in MARC record handling for ZOOM.
1347 New option for YAZ client, -k <kilobytes> that sets
1348 maximum record size. Similar to -k option for generic frontend
1349 server and yaz-ztest.
1351 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1353 Prefix query parser reports "fail" when bad attribute set is given.
1355 Fix in MARC decoder. Proximity logging. Fix for attribute set
1356 in scan handler for server. Patches by Shigeru Ishida.
1358 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1361 Configure option --with-openssl=<dir> now works when a directory is
1362 specified. Patch provided by Morten Bøgeskov.
1364 New option for YAZ client, -u <auth>, that sets authentication.
1366 ZOOM fix: error information was sometimes "missing", since error
1367 was cleared/reset too when it shouldn't.
1369 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1371 --- 1.8.4 2002/01/04
1373 Scan for ZOOM API. New object ZOOM_scanset. New functions
1374 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1375 ZOOM_scanset_destroy.
1377 New ZOOM function, ZOOM_connection_last_event, that returns type
1378 of last event (such as "receive data", "send data", "apdu received",
1381 New ZOOM option, schema, that specifies schema for retrieval.
1383 New CCL feature. Qualifiers can be aliases for one or more
1384 other qualifiers (if more than one is given, OR is used).
1386 ZOOM uses named result sets if target supports it.
1388 Two new YAZ client commands: . (dot, which sources a script of YAZ
1389 client commands), and ! (to execute shell command.). Implemented
1392 Working on Debian packages.
1394 --- 1.8.3 2001/11/19
1396 YAZ client enables named result sets only if target supports it.
1398 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1400 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1401 with key="host" to get same result.
1403 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1404 Function Z3950_resultset_record(s) returns references to records
1405 "owned" by resultset. To become owner use Z3950_record_clone.
1407 Function z_ext_record handles Extended Services. Thanks to
1410 --- 1.8.2 2001/11/12
1412 CCL Parser fix: ignore token comma when dealing with and-lists.
1414 Documentation updates for COMSTACK.
1416 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1417 Changed prototype Z3950_records. For some functions, int parameters
1418 were changed to size_t.
1420 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1423 New MARC decode/display function, marc_display_exl, which properly rejects
1424 non-ISO2709 records. YAZ client uses it.
1426 --- 1.8.1 2001/10/29
1428 Fix bug: local attribute set wasn't set correctly in PQF strings.
1432 * Old Z39.50 codecs no longer supported.
1434 Added ZOOM C binding. See http://zoom.z3950.org/
1436 Renamed states for COMSTACKs to avoid confusion with events.
1438 Implemented cs_look and proper cs_rcvconnect.
1440 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1442 Configure detects POSIX threads on OpenBSD.
1444 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1445 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1447 When error is returned from present handler, non-surrogate diagnostic
1448 is returned in present response (and fetch handler is no longer called).
1450 * Minor adjustments to pquery parser (PQF). Token characters may be
1451 escaped by using backslash (C-style).
1453 PQF parser allows string attribute values to be specified. For @attr,
1454 non-numeric characters after the equal-sign are treated as strings
1455 (e.g. @attr 9=title).
1457 CCL trunction character may be defined (@truncation in file)
1459 * function zget_ExtendedServicesRequest sets waitAction to
1460 waitIfPossible (was wait).
1462 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1465 CCL operator names may be set in field definition files (CCL_bibset).
1466 See ccl/bib1 for an example.
1468 Fixes in ASN.1 compiler for C++ compatibility.
1470 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1471 and "op_or" to avoid conflict with C++.
1473 Fixed problem with GNU readline detection on Redhat 7.0.
1475 Added step-size for Scan backend handler.
1477 Fixed bug that made the frontend server crash when no attribute
1478 set was specified for scan.
1480 Front-end server automatically switches to original working directory
1481 when installed as an NT service. Previously -w had to be specified to
1484 Added extended attributes for retrieval module (data1), so that data1
1485 records carry d1_readXML/SGML attributes. d1_read also supports
1486 null-data rules ( <tag/>)
1488 On UNIX when POSIX threads are available, a separate library libyazthread
1489 is created. Programmers should link with that library and the yaz library
1490 when using threads. The reason for the split was that some applications
1491 on Linux, such as Apache, doesn't work well when using shared objects that
1494 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1495 (or any frontend server) in SSL mode by specifying ssl: followed by
1496 address. Only tested on UNIX.
1498 Added feature for CCL module. Virtual structure s=al or s=ol generates
1499 and-list and or-list respectively instead of phrase search.
1503 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1504 log_mask_str. This was done to avoid name conflicts with other libraries
1505 (such as other PHP extensions).
1507 Added raw OID member for preferred record syntax (request_format_raw)
1508 and returned record syntax (output_format_raw) for backend fetch method.
1510 Config file yaz-config now accepts options so that it returns specific
1511 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1513 Shared library support for UNIX using GNU libtool.
1515 * Modified backend interface. Request/Response struct's replaced by
1516 one read/write C struct. For example bend_fetchrequest and
1517 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1518 Every handler - even search has to be registered in bend_init
1519 handler. This means that the YAZ library no longer refers to
1520 external functions and it makes it possible to make the whole
1521 thing a single DLL/SO.
1523 Added Segment handler for backend server.
1525 Added Zmbol/Zebra administrative functions to YAZ client.
1527 Threaded frontend server on UNIX (when POSIX Threads are available).
1528 Starting the server with option -T enables multi-threading.
1532 Added configure option --enable-comp/disable-comp to control use
1533 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1534 located in sub directory asn.
1536 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1537 in ${exec_prefix}/bin along with the other programs yaz-client and
1540 GNU automake used to maintain makefiles.
1542 Added several OID's.
1544 Changed retrieval module so that we can load records with no abstract
1545 syntax defined. Tagpaths in these records are fully composed of string
1548 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1552 On UNIX, the generated makefile now supports a proper 'make install'.
1553 The prefix can be set via GNU configure to set the install location
1554 (default is /usr/local).
1556 * YAZ programs client and ztest were renamed to yaz-client and
1557 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1558 locations, such as /usr/bin,/usr/local/bin,etc.
1560 * YAZ Header files were moved from include to include/yaz. YAZ Header
1561 files are referred to as include <yaz/log.h> rather than <log.h>.
1562 The YAZ include path (-I ..) is therefore the same as before. Programmers
1563 should update their #include statements or use -Ipath/include/yaz
1564 instead. The main motivation for doing this change is that YAZ header files
1565 can be installed in "standard" locations /usr/include,/usr/local/include
1566 without introducing conflicts, since ALL YAZ header files are stored
1567 in subdirectory yaz (under /usr/include for example).
1569 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1570 rather than project/workspace files. We switched because project files
1571 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1574 Changed name of logging function, logf, to yaz_log, to prevent name
1575 clash with some math-log functions. The YAZ header log.h defines logf
1576 to yaz_log (#define) so there should be no incompatibilities by this
1579 Added bend_start/bend_stop handlers for server. These handler are
1580 called on start/stop of server. For windows they are called whenever
1581 a service is started/stopped.
1583 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1584 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1585 in util/yc.tcl. The auto-generated C code structures are, in a few
1586 cases, incompatible with the old decoders. There are differences in the
1587 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1588 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1589 The preprocessor variable ASN_COMPILED is defined when the compiled
1590 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1591 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1592 wish to use the old encoders/decoders you can specify --disable-yc
1595 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1596 version so that it supports both new - and old version of DB Update
1598 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1599 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1600 change. The name parameter can be set to 0 in which no name is specified
1601 for the construction. The macros odr_implicit and odr_explicit sets name
1602 parameter to zero for the construction involved. New macros
1603 odr_implicit_tag and odr_explicit_tag are similar to the others,
1604 except that a name parameter is added. For programmers' that don't use
1605 ODR they probably only need to change the call to z_APDU and z_External.
1607 Added access control facility by interfacing the TCP wrapper library.
1608 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1609 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1610 name of the daemon and enables the access control as specified in
1611 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1613 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1614 den Dool <H.M.vdnDool@kub.nl>.
1616 Added reference ID parameter to most functions in server API - refer
1617 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1619 Changed name of ccl library to libccl.a (was ccl.a).
1621 Fixed bug in decoder for Explain (Category TargetInfo).
1623 Added support for GNU readline in client. Thanks to Jacob Poulsen
1624 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1626 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1627 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1628 IMPLEMENTATION! This change was made to the development version before
1629 the ZIG decided to retract the amendment. If any users MUST be
1630 compatible with the original Update definition, PLEASE CONTACT US, and
1631 we will include a separate definition corresponding to the old Update
1632 ES. Note that because of the change to the ASN.1 of the
1633 TaskPackageRecordStructure we cannot define a single structure that
1634 will support both versions.
1636 * Added const modifier to buffer parameter for some ODR/BER encoding
1637 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1638 completeWAIS, odr_dumpBER.
1640 Fixed bug in client.c which caused a crash when a scanResponse didn't
1641 contain positionOfTerm.
1643 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1644 * will cause an error in a client if a non-YAZ target sends both a
1645 * list of Scan entries and non-surrogate diagnostics.
1647 Retrieval module enhancements. Tag sets may be typed in the reference
1648 to it. From the .abs-file the "tagset" directive takes a third optional
1649 integer type for the tag set referenced. From a .tag-file the "include"
1650 directive takes a third optional type as well. The old "type" directive
1651 in the tag set itself is still recognized but acts as the default type
1654 Backend interface change. Individual Scan terms returned from bend_scan
1655 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1656 in include/backend.h.
1658 Retrieval module enhancements. Multiple tag sets and attribute sets may
1659 be specified in abstract syntax specs. Revised the error/warning for
1660 logging messages reported by the retrieval module when reading the
1663 Object Identifier system (oid_..) changed. The API is backwards
1664 compatible but the oid-routines now allocates new OID's when needed.
1665 Raw OID's may be specified in oid_getvalbyname.
1667 YAZ now uses GNU configure to generate Makefile(s).
1669 * Minor changes in some of the member names of DeleteResultSetRequest and
1670 DeleteResultSetResponse. See include/proto.h.
1672 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1673 and added member 'languages' in TargetInfo (which was missing).
1675 Changed the way attribute sets are handled in the retrieval
1676 module. These are now cached, just like the abstract syntaxes
1679 Changed YAZ so that it links with compiled ASN.1.
1681 Added Explain-schema definitions and mapping routines. The following
1682 Explain categories have been implemented: AttributeDetails,
1683 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1685 Fixed minor bug in Windows version of Server Library.
1687 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1689 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1691 Added EXTERNAL: UNIverse Resource Report (non-standard).
1693 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1694 ENUMERATED and SET OF.
1696 * Added 'const' to some of the char pointer arguments for the
1697 functions, data1_read_node, data1_getelementbytagname,
1698 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1701 Fixed bug in data1_insert_taggeddata - the last_child member of
1702 parent wasn't initialised.
1704 * Changed data1_read_record and data1_read_node so that the supplied
1705 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1706 doesn't refer to any parts of the "SGML"-buffer.
1708 Fixed bug in server library (Windows version of statserv_remove).
1710 * Changed code so that it compiles as C++. The type definition
1711 of Odr_fun which is a member of Odr_arm was changed. The result is,
1712 that an explicit typecast is needed for the fun pointer when
1713 using Odr_arm - as in:
1714 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1716 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1718 Implemented the new structured date and time definition as approved
1719 by the ZIG. Added schemaId element to the specificTag in Espec-1
1720 (also approved at the last ZIG). Thanks to RVDM.
1722 Added some Object identifiers (RVDM).
1724 Changed the Update Extended Service (RVDM).
1726 Added command "refid" to client which specifies referenceId for
1727 the following requests.
1729 Implemented extended service handling for server. See ztest.c
1730 for an example as well as backend.h. New handlers are registerd
1731 in the Init handler.
1733 * Changed interface for sort in server.
1735 Added new members to statserv_options_block. It allows a server
1736 to read options from another source than just the command line. Thanks
1737 to Charles Woodfield.
1739 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1740 renamed to zboolean. Some C++ compilers complained about the name.
1742 Minor changes to gils.abs. Added index 's' (sort) on title
1743 and date/time-last-modified.
1745 --- 1.4pl2 1998/1/30
1747 Fixed bug in server library regarding inetd mode (-i). This bug
1748 was introduced by release 1.4.
1750 --- 1.4pl1 1998/1/29
1752 Added sort facility in client and backend server interface.
1754 Fixed problem with dependencies in Makefile(s).
1756 Fixed bugs for encoders/decoders of extended services and
1759 Implemented sub-tree feature for schemas. Sub-trees are
1760 referenced in *.abs-files. See explain.abs for an example
1761 of the use of this feature.
1763 Modified bib1.att; local attributes for ANY didn't include
1764 ANY itself (only affects use of the retrieval module).
1766 Fixed bug in plain SGML reader in function data1_read_node:
1767 tags with prefix "var" was incorrectly interpreted as variants.
1769 Added feature "sub-schemas" to enable references to - and definitions
1770 of - group of elements.
1772 * Removed member parent from type data1_element (in data1.h).
1774 Implemented function odr_nullval() that returns the value of
1777 * Removed member num_children from data1_node (in data1.h).
1779 Made NT service interface part of the server library. The
1780 function statserv_main uses the NT service when required and
1781 calls the statserv_start / statserv_close routines.
1783 Routine zget_SearchRequest and zget_PresentRequest fills
1784 resultSetName/Id member with "default" instead of "Default".
1786 Fixed memory leak in server. Request queue member wasn't freed.
1788 Fixed nmem_exit so that memory is freed.
1792 Revised the CCL parser utility to be thread safe.
1794 Added function, oid_ent_to_oid, to replace the function
1795 oid_getoidbyent, which is not thread safe.
1797 * Added nmem_init and nmem_exit to initialize and release
1798 NMEM resources. Function nmem_init should be called once in the
1799 initial thread before NMEM/ODR is used. statserv.c and client.c
1800 have been changed accordingly. The change was necessary to make
1801 NMEM thread safe. The NMEM memory pool is shared amongst threads
1802 in a process. Unix-based applications will still work fine without
1805 Added NT Services interface for the the Z39.50 (statserv) Server.
1806 Refer to the ztest.c source on the usage.
1808 Windows 95/NT port using MSVC5.0. Project files are included in the
1811 * Defined new 'global' handle for the retrieval (data1) system. The
1812 new handled, data1_handle, describes the state of the data1 system.
1813 This handle is passed as first argument to virtually all
1814 data1 related routines. The functions data1_create and data1_destroy
1815 creates and destroys a data1 handle respectively.
1817 Added ODR encode stream member to all backend request structures
1818 init, search, scan etc. This stream should be used to allocate all
1819 memory used for the response when thread safe operation is needed.
1821 Changed the comstack utility, cs_addstr, to be thread safe. The
1822 returned hostname string returned by the function is now part the
1825 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1826 function. The cs_straddr takes a COMSTACK handle as argument, so this
1827 function must be used after cs_create and before bind/connect.
1828 This function is thread safe.
1830 Moved test server to 'ztest' directory - generic server code still
1831 in 'server' directory.
1833 Made prefix query (pquery.c) utility thread safe.
1835 Added new function modifier YAZ_EXPORT to 'export' public DLL
1836 functions when using windows (see include/yconfig.h).
1838 Added definitions to the OID database (util/oid.c) (RVDM).
1840 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1842 Added call to ccl_rpn_delete in client program.
1844 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1845 release of RPN structure.
1847 Added support for C++, headers uses extern "C" for public definitions.
1848 With input from RVDM.
1850 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1851 Thanks to Ronald van der Meer (RVDM).
1853 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1855 Added support for private extensions to the OID database
1856 (oid_setprivateoids()). Thanks to RVDM.
1858 Added optional, physical ANY (key replication)
1860 Fixed null-reference problem in GRS-1 output filter.
1862 Proximity operator added to Prefix Query Format (PQF).
1864 In test client command "base" accepts multiple databases.
1866 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1870 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.

1882 Added Update extended service.
1884 Added SearchResult-1 additional info structure.

1889 --- 1.2 1996/6/10 (1st anniversary release)
1891 Added Summary record syntax. Lightly tested.
1893 Added OPAC record syntax. Untested.
1895 Added ResourceReport service encoders/decoders. Untested.

1903 Added documentation of query-language parsers and other supporting utilities.
1905 [frontend-server] Added Attribute set to the bend_scanrequest API.
1907 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1908 surrogate diagnostics were generated.
1910 [retrieval] Allow multiple local values for attribute.
1912 [retrieval] Allow multiple attributes per element in .abs files. index type.
1914 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1916 --- 1.1pl2 1996/4/10
1918 Minor changes, mostly specific to Zebra's requirements (retrieval)
1922 Repaired bug in frontend server when running multiple listening
1923 endpoints in dynamic mode.
1925 z_External() now won't break if a known, ASN.1 value comes encapsulated
1926 in an octet-string. The value will pass through unmodified in an Odr_oct.
1928 Added a bit of code to the demo client to decode & display
1929 ASN.1-structured records represented in the octet-aligned branch of
1930 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1932 Added z_ext_getentbyref() to the ASN module. Doc updated.
1934 * Completed the SCAN definition in the ASN module. This may break SCAN
1935 code based on older YAZ-versions at compile-time. The fix is easy -
1938 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1939 under the SCAN definition. Remember to initialize this, server-people.
1941 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1942 that this does not extend to ODR and ASN.
1944 Comstack allows insertion of established socket (primarily for
1945 inetd-operation of servers). Doc updated.
1947 Front-end server can now start from the inetd in TCP mode. Doc
1950 --- 1.0pl4 1996/1/24
1954 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1955 the rank and record number.
1957 Adjustments to the frontend server.
1959 Fixed diagnostic BER dumper. It ignored the file argument.
1963 Various changes to retrieval module.
1965 Changed the union discriminators of the protocol files from enums to
1966 ints paired with #defines.
1968 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1971 *Changed operator in the RPN structure to 'roperator', again to avoid a
1974 Fixed problems in Explain decoders/encoders.
1976 --- 1.0pl2 1995/12/6
1978 Memory bug in log module fixed.
1980 --- 1.0pl1 1995/12/5
1982 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1984 Bug in Explain DatabaseInfo module fixed.
1986 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1990 The shift to v1.0 signals that we now consider the *core* functionality
1991 of YAZ reasonably stable (the core being more or less equivalent to
1992 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1993 tested (Explain not at all - though that will happen soonish).
1995 Minor changes to code to support Windows port.
1997 Various minor changes after we're getting to use GRS-1 & co. more.
1999 Added Espec-1 format.
2001 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2002 of the protocol and it cannot be selected when encoding (maps into 'string'
2003 when decoding). Needed to talk to some servers.
2005 Demo client can request simple element set names.
2007 Added Diagnostic Format encoders/decoders.
2009 Added simple Close handling to frontend server (no hooks for resource
2010 reporting yet), and demonstration client.
2012 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2014 --- 1.0b3 1995/08/24
2016 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2017 handled incorrectly when records were requested in the searchResponse. This
2018 will only affect you if you use the frontend-server.
2020 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2021 Test-client will ask for and print GRS1. Ztest will return dummy records
2024 Added Explain encoders/decoders to the service-level API. Untested.
2026 Added Extended Services: Item Order encoders and decoders to the Service-
2027 level API. Untested. We could use a recent copy of the pertinent bits
2028 of the ILL protocol to add those bits.
2030 Added diagnostic format 1 encoders/decoders to the service-level API.
2033 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2034 odr_cons.c, which causes a more correct output.
2036 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2037 was always set to 0 when no records were requested in the searchRequest.
2039 * Added better external-handling. This shouldn't harm old code that
2040 *encodes* externals. It can break code that looks for a
2041 'single-ASN1-type' representation, since those types that are known
2042 are now decoded immediately. Look at the SUTRS sample code in
2043 seshigh.c and client.c. Documentation updated.
2045 Handling of structured records in bend_fetchresponse. Length -1 marks
2046 structured record, type is deduced from format field.
2048 --- 1.0b2 1995/06/27
2049 Fairly quick maintenance release to add SUTRS support.
2051 Fixed handling of SUTRS records in the demonstration client.
2053 * Added format field to the bend_fetchrequest and bend_fetchresponce
2054 structures of the backend API (frontend server). When the record is
2055 returned, the value of the format field is mapped to an OID. The
2056 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2057 of the record. The special value VAL_NONE in the bend_request means
2058 that no specific format was requested by the client. Documentation
2059 updated accordingly. Test server (ztest) will return a fixed dummy
2060 SUTRS record if your client requests SUTRS.
2062 Documentation updated accordingly.
2064 You can now set external libraries and RANLIB support in the top-level
2068 First public release.
