3 Extended ZOOM result set options with two options that may be read by
4 a client: resultSetStatus and presentStatus with values as specified for
6 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
8 Fixed bug #827: Using SSL fails on Debian etch.
10 Fixed bug #826: Weird looking chars for set of MARC records.
12 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
13 that is treated as an ItemOrder with itemRequest being an XML document
14 external. The value of "doc" is the content.
16 Extended the GFS search facility. New member of bend_search_rr
17 'estimated_hit_count' signals that hits is known to be an estmate
18 (higher or lower than real hit count). New member 'partial_resultset'
19 signals that the search was partial (hit count is lower or equal than
20 real hit count). For Z39.50, the information is stored in resultSetStatus
21 member of SearchResponse APDU. For SRU, the information is signalled
22 via SRU diagnostic 59: "Result set created with valid partial results
25 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
29 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
31 Added ZOOM_connection_peek_event.
33 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
34 the following new functions:
35 ZOOM_event_nonblock, ZOOM_connection_process,
36 ZOOM_connection_get_{socket,mask,timeout},
37 ZOOM_connection_fire_event_{timeout,socket}.
38 The existing blocking event handler, ZOOM_event, is a wrapper for the
39 + blocking ZOOM_event_sys_{poll,select}.
41 Implemented function ccl_xml_config which parses XML version of CCL
42 configuration (bug #798).
44 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
46 Added timings utility (yaz/timing.h)
50 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
53 Fixed bug #779: Rotation of apdu.log fails.
55 Fixed for character set conversions:
56 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
57 Honor G1 set in MARC-8 decoding.
61 Fixed bug #775: char conversion does not handle Alternative UTF-8
64 Implemented function yaz_marc_read_line which parses MARC line format
65 records. There is a wealth of formats out there. So far, this function
66 reads line records produced by yaz_marc_write_line.
68 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
69 more generic and easier to remember(!) options: -i format and -o format
70 which specifies input format and output format respectively - where
71 format is one of "marc", "marcxml", "line", "marcxchange".
73 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
74 does not print anything except warnings for records.
76 For yaz-marcdump, added support for MARC split into files (-s) with a given
79 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
80 spec, at http://www.loc.gov/standards/sru/record-update/
81 This has changed the binary layout of the following structs:
82 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
83 bend_update_rr . Patch by Ko van der Sloot.
85 Added GFS utility function bend_assoc_is_alive which returns 1 if
86 association is still alive (client is connected); 0 otherwise (client
87 closed connection). This allows busy servers to stop working for
90 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
91 been a separate piece of software. This version of ziffy has been modified
92 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
94 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
96 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
97 Client code may now interrogate options such as "init_opt_sort" to
98 find out whether the server claims to support various options.
100 --- 2.1.40 2006/11/27
102 Added utilities yaz_{set,get}_esn to set/get element set name from
105 Removed the build of libyazthread.la. The libyaz.so is the threaded version
106 of YAZ and has been so since YAZ 2.1.10.
108 Implemented ZOOM_record_error which returns error information for
109 record (surrogate diagnostic).
111 --- 2.1.38 2006/10/31
113 Updates for SRU Update by Ko van der Sloot:
114 1. Changed name from "operation" to "action"
115 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
116 versions in the code, marked as 'backward compatible'.
117 3. Added diagnostics for SRU Update.
119 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
121 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
123 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
125 For GFS, fixed problem with SRU diagnostic 'First record position out of
126 range' being issued for 0 hits.
128 zoomtst10 part of Windows Build.
130 --- 2.1.36 2006/10/13
132 Implemented yaz_filepath_comp which splits a path into file path
133 components (required by Zebra 2.0.3+).
135 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
136 BSD inspired license until now so this should not have any real impact on
137 anybody. See http://www.opensource.org/licenses/bsd-license.php
139 Fixed bug #687: Missing log lines.
141 Fixed bug #678: CQL to PQF translation does not preserve double-quote
144 Fixed bug #689: SRU diagnostics to be added.
146 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
147 whether a connection is idle (no more work do do).
149 --- 2.1.34 2006/10/04
151 Change type of optval from long to int for invocation of setsockopt with
152 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
154 Added support for specifying the max log file size for the Generic
155 Frontend Server. The size is given with option -r.
157 --- 2.1.32 2006/09/21
159 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
161 --- 2.1.30 2006/09/17
163 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
166 Fixed bug in Generic Frontend Server that could cause a server to stop
167 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
169 For the generic frontend server, the maximum record size is used as maximum
170 size of incoming packages (SRU + Z39.50). The value until was previously
171 only used in Z39.50 Init negotiation and, later, in a session controlled
172 sizes of records returned. This is controlled using -k option. It can be
173 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
175 --- 2.1.28 2006/09/04
177 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
180 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
182 New option for yaz-marcdump -lpos=value which allows setting a portion
183 of MARC header to a certain value.
185 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
187 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
188 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
190 --- 2.1.26 2006/08/15
192 Fixed problem with SRU mode type (soap, get, post) for yaz-client
195 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
197 --- 2.1.24 2006/08/08
199 Fixed MARC ISO2709 encoding routines to deal with character set
202 Minor changes to GFS logging. Database included in search request log
205 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
206 cached/multiple records.
208 Shared libraries are built by default on Unix+configure.
210 Changed cql2pqf transformation to use a different evaluation order. The
211 new order is: always, relation, structure, position, truncation, index
212 and relationModifier. Old order was: always, relation, relationModifier,
213 structure, index, position, truncation. Note that the the latter ones
214 override former ones for identical attributes.. The new scheme means that
215 it is possible to override any existing attribute with a relationModifier.
216 And also that it is possible to override everything for the index rule
217 (except the ones listed in relationModifier). No order is perfect but this
218 one, we believe, covers more real cases.. The "always" should have been
219 called "default", since the attributes there can be overridden with all
222 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
223 compilation phase, but also for yaz-config --cflags output. This allows
224 us to have public headers with Libxml2 stuff in them . It should also,
225 eventually, make Libxml2 checks redundant in packages using YAZ, such
228 --- 2.1.22 2006/06/15
230 Changed SRU update structure bend_update_rr so that SRU diagnostics are
231 stored in uri, message and details.. Previously diagnostics were stored
232 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
233 compatibility.. but he's probably the only one affected, so.
235 Added support for CCL, compiled on the client side, in ZOOM-C. This
236 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
237 input; the resulting query objects can be used for for searching with
238 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
240 YAZ' configure searches for OpenSSL by default.
242 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
243 SL_CTX_use_certificate_file. See
244 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
245 for more info. Thanks to Ko van der Sloot.
247 --- 2.1.20 2006/06/02
249 Bug #600: SRU GET, POST support for yaz-client. Introduced
250 command 'sru' which selects method SOAP/GET/POST.
252 Allow missingValueAction to be specified for the sortspec string -
253 function yaz_sort_spec. By default, the missing value action is null.
254 Use ! to specify "abort". Use = followed by stringvalue to specify default
257 Ensured that Present-handler (if defined) is called in GFS before any call to
258 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
259 searchRetrieve requests.
261 Documentation for YAZ is now based on the Docbook XML/XSLT using
262 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
263 is no longer depending on jade/openjade or docbook-to-man scripts.
264 PDF is no longer part of the distribution - but can optionally be
265 made using DSSSL/jadetex or FOP.
267 Added retrieval handling support in Generic Frontend Server to support
268 conversion between MARC/XML as well as XSLTtransforms. See
269 etc/yazgfs.xml for an example.
271 Added Authentication support to Generic Frontend Server in SRU
272 mode. Authentication using HTTP Basic is supported, as is the use
273 of 'x-username' and 'x-password' parameters in the request itself.
275 Added support for a new character set MARC8s identical to MARC8 except
276 that it converts combined characters to single Unicode characters in the
277 Latin-1 range (when possible).
279 --- 2.1.18 2006/04/24
281 ASN.1 compiler 0.4: generates brief Doxygen file header for
282 generated .h/.c files.
284 Utility yaz_iconv now supports conversion to MARC-8.
286 New facilities for the MARC module. The reading - and writing of
287 content are separate methods for the yaz_marc_t handle. The following
288 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
289 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
290 format). Write functions have prefix yaz_marc_write_.. The existing
291 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
292 available. Removed support for OAI-MARC and simplexml (not the
293 simplexml from PHP5).
295 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
296 to be returned for this connection.
298 --- 2.1.16 2006/03/31
300 Allow multiple languages and charsets to be specified with
301 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
302 negcharset iso-8859-1,utf-8
304 Translation of proximity nodes from CQL into PQF now works.
306 Moved to automake 1.8, 1.9.
308 Added function yaz_log_set_handler which allows a log handler to be
309 installed. This handler will be called for all log messages. Output
310 to file is also produced; but that can be disabled by passing NULL
311 fname to yaz_log_init_file.
313 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
315 For SRW (including GFS), accept application/soap+xml as content-type
318 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
319 produces NO stylesheet reference even if a default stylesheet is specified
322 --- 2.1.14 2006/03/14
324 Updated Windows package to include yazd.dll + yazd.lib for the
325 Development component.
327 If the environment variable YAZ_LOG is set, then it is used as a
328 string indicating the default level of logging to use if not
329 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
330 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
331 used as before. So, for example, to omit warnings from YAZ logging,
334 cql_transform() now map structure and other attributes before indexes,
335 so that index-specific structures and other attributes can override
336 defaults. So now a combination of mapping specifications such as:
338 index.dc.date = 1=date-modified 4=5
339 does the right thing.
341 cql_transform() now also respects the "always" mapping specification,
342 which establishes an initial set of attributes to be used for all
343 terms except where overridden by more specific attributes associated
344 with the index, relation or modifier.
346 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
347 which mode to use; one of "post", "get" or "soap" (SRW, default).
349 Fixes for yaz_iconv routines: changed trie-based character set conversions
350 to use only non-negative values for bit fields due to Sun's C compiler not
351 supporting negative values.
353 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
354 sequences where not read correctly. Fix by Rustam Usmanov.
356 Updated win/makefile to use options, settings which makes things
357 compile with VS C 2005.
359 --- 2.1.12 2006/02/01
361 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
363 In ZOOM socket code, use select instead of poll on MacOSX.
365 ZOOM-C now support client-side compilation of CQL into RPN that is
366 sent to the server, enabling CQL to be used against all Z39.50
367 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
368 ZOOM_query object, and submit it using ZOOM_connection_search().
369 The CQL-to-RPN translation uses a configuration file, the name of
370 which must be specified in the Connection's "cqlfile" option.
372 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
373 function, which takes as its start-term parameter a ZOOM_query object
374 (which may have had either CQL or RPN set into it).
377 --- 2.1.10 2005/11/29
379 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
380 GFS to support this as well. Backend handler, bend_srw_update, does the
381 update work. Code contributed by Ko van der Sloot.
383 Allow retrieval of Search Result-1 information in ZOOM by the use of
384 options that are attached to a result set. ZOOM documentation updated
387 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
388 UTF-8 conversion. Patch by Raj Patel.
390 Added option -m to GFS to control formatting of timestamps in log file.
392 Added 'exit' as synonym for 'quit' in yaz-client
394 Added support for specifying SRW resultSetId + resultSetIdleTime in a
395 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
396 for the new members. Patch by Ko van der Sloot.
398 Added support for SRU POST. It is supported for content-type
399 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
401 Do not build the separate Multi-threaded (MT) library libyazthread.la.
402 Instead make the library libyaz.la multi-threaded. Threading as a whole
403 can still be disabled by configure option --disable-threads. Previosly,
404 with older GLIBCs there were problems with MT libs under Apache. This
405 has now been fixed a long time ago.
407 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
410 CQL module modified to be case insensitive for relations/indexes/operations.
412 Fixed bug in CQL transform code: incorrect value relationModifieder
415 Added 'show all' command for yaz-client which retrieves all results
418 Added new yaz-client, xmles, which takes a (private) OID and
419 a document to be sent as an extended service request.
421 Describe new yaz-client commands wait_response and set_auto_wait.
423 Increase TCP/IP listener backlog from 3 (which I am guessing was
424 copied from the SunOS manual entry way back when) so SOMAXCONN, so
425 that the socket will queue as many incoming connections as it's able
426 to handle ongoing connections. In other words, it will never now
427 refuse a connection that it would be able to handle merely because
428 it's not got around to accepting() enough of the pending connections
429 yet. This is the behaviour anyway under Linux, where the listen()
430 argument is ignored; but not under BSD and on systems such as
431 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
432 YAZ-based servers should now be uniform across operating systems in
435 yaz-marcdump uses 64-bit file access on some systems. This is enabled
436 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
437 This allows yaz-marcdump to read large MARC batches (>2 GB).
439 Modified all YAZ source files - except the source which is auto-generated
440 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
443 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
444 corresponding to the existing *_setl() function. These allow option
445 values containing arbitrary valuues.
447 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
448 ZOOM_resultset_sort() in new applications. Its behaviour is identical
449 except that it returns an indicator of whether or not the sort
450 criterion was accepted (0 for OK, -1 for invalid).
454 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
455 MARC output rather than returning "new" buffer.
457 yaz-client warns about unknown init options.
459 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
463 Added support for SRW sort in Generic Frontend Server. Patch
464 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
465 sortKeys - or NULL if none is provided.
467 Fixed bug #307: It was impossible to specify indefinite/no timeout
468 for ZOOM_event. Special timeout value -1 now means indefinite timeout
471 Added support for multiple languages and charsets to be specified in
472 ZOOM. Each charset/language is separated by a blank. If negotiation is
473 in effect in init-response, Option
474 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
475 Code based on patch by Vasiliy Osadchuk.
477 Fixed bug #306: infinite recursion that occurred when calling
478 yaz_log_level_init as the first call (before other log level or
481 Fixed bug in scan handling in front end server: if preferred-Position-In-
482 Response was non-present, a NULL pointer referece was performed.
486 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
487 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
488 now defined for all those error codes. So instead of putting 109 in
489 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
490 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
492 Modified the yaz-marcdump utility to skip garbage bytes between MARC
495 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
497 Program yaz-client now exits and produces an error message if multiple
498 Z39.50 servers are specified on the command line (none or one allowed
501 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
506 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
508 Fixed bug #272: Preserve spacing for CCL terms.
512 Added support for virtual hosts and multiple backend servers for
513 the YAZ frontend server. The configution is XML based and
514 support specificition of CQL to RPN mappings and explain information.
515 See section "Virtual Hosts" in the YAZ manual.
517 Extended OPAC display utility. OPAC display utility renders
518 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
519 to supplement yaz_marc_decode_wrbuf.
521 Fixed a bug in MARC decoder that could caused it to crash for some
522 invalid MARC records. More diagnostics and warnings where added in
523 XML output (warnings, etc are stored in comments).
525 --- 2.0.34 2005/02/08
527 Fixes for UNIX domain sockets. Bug #261.
529 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
531 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
532 Added yaz_marc_subfield_str which defines subfield lead string which is
533 used in YAZ_MARC_LINE format. Default string is blank+$. Added
534 yaz_marc_endline_str which defines end of fields string used in
535 YAZ_MARC_LINE format. Default string is newline.
537 Experimental support for MarcXChange. This format can be produced
538 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
539 http://www.bs.dk/standards/MarcXchange.xsd
541 Added yaz-client commands scansize that sets maximum number of
542 entries to be returned by scan.
544 --- 2.0.32 2005/01/11
546 Added support for SRW scan in yaz-client and Generic Frontend Server.
548 * Added whereInList member to SRW Scan Term.
550 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
552 Fixed NMEM system to return aligned blocks on the smallest boundaries
553 that are suitably aligned for all possible types on the particular
554 architecture YAZ is being built for.
556 --- 2.0.30 2005/01/04
558 Fixed numerious warnings that was issued with newer versions of GCC.
560 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
561 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
564 Make YAZ Generic Frontend Server slightly faster.
566 Enhance (and reduce) logging for Generic Frontend Server.
568 Revert YAZ log system so that it flushes every write operation
569 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
571 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
572 instead of LOG_, due to name clash with syslog(3). LOG_ are still
573 present. New applications should define YAZ_USE_NEW_LOG=1 - this
574 will effectively disable old definitions.
576 --- 2.0.28 2004/11/09
578 Added yaz_log_time_format which specifies log format using
581 Added yaz_log_module_level which returns mask for a module. Value
582 is non-zero mask a if module is enabled; zero if disabled.
584 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
585 in include/yaz/cql.h.
587 Fixed bug #176: Dont throw diagnostics on empty SRU args.
589 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
591 Fixed bug #172: RPM builds does not enable SSL.
593 Doxyfile.in part of dist. Doxyfile generated by configure.
595 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
596 are given and the corresponding component does not exist.
598 Extend CCL documentation in YAZ reference. Describe r=r.
600 --- 2.0.26 2004/10/01
602 Fixed MARC->MARCXML conversion to properly deal with
603 fields, subfields, indicators having non-ASCII characters.
605 Fixed MARC->MARCXML conversion so that ASCII control characters
606 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
609 Added YAZ GFS support for conversion from Z39.50 surrogate
610 diagnostics to SRW surrogate diagnostics.
612 Bug fix: YAZ GFS did not return schema in explainResponse.
614 --- 2.0.25 2004/09/30
616 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
617 now converts recordSchema to elementSetName as well as schema URI.
619 Fixed bug in COMSTACK that prevented HTTP request packages from being
622 --- 2.0.24 2004/09/29
624 Added CCL facility r=r "range" which is similar to r=o "ordered" but
625 does not require white-space before and after the dash in a range, e.g.
626 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
629 Fixed a few AC_TRY_LINK configure tests that did not operate properly
630 due to new GCC removing "redundant" code.
632 Added yaz-client commands scanpos and scanstep that sets preferred
633 position and step-size for scan.
635 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
637 Added CCL utility ccl_qual_buf which parses one or more CCL
638 spec lines in a buffer.
640 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
641 of name and value - ignoring empty lines and comments.
643 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
645 Added odr_get_element_path which returns current element path for an
646 ODR handle. This utility is useful in error handling or user-defined
649 Added ODR_PRINT utility odr_set_stream which is is a more generic
650 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
651 to a write function and pointer to close function. The close function - if
652 non-NULL - will be called during odr_destroy.
654 Fixed bug in CCL parser where truncation char was not removed from
655 right side when truncation=both was in effect.
657 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
660 --- 2.0.23 2004/08/11
662 Fix buffer overrun in CQL parser when dealing with proximity (%).
664 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
665 to UTF-8/UCS conversion is now only based on codetables.xml.
667 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
669 --- 2.0.22 2004/08/06
671 Add support for more "commit changes" in ZOOM (uses Extended Services).
673 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
676 Yet another small fix for configure of SSL.
678 --- 2.0.21 2004/05/14
680 Fix SSL libs for configure when --with-openssl=DIR is given.
682 --- 2.0.20 2004/05/10
684 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
686 SSL comstack now uses yaz.pem certificate file on server side
687 by default. Certificate filename can be configured by calling
688 comstack function cs_set_ssl_certificate_file before cs_bind is used.
690 Fix bug regarding multiple calls to ZOOM_connection_connect.
692 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
694 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
695 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
697 ZOOM now allows inspection of X509 peer certificate for verification.
698 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
700 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
701 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
702 as "modular" but it simplifies things.
704 Added cs_get_peer_certificate to that returns peer X509 PEM.
706 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
707 NULL if SSL is unavailable.
709 Documentation about MARC decoding tools.
711 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
713 --- 2.0.19 2004/03/30
715 Rename CHANGELOG to NEWS to follow GNU style packing.
717 Fix bug with missing initialization of member in init_diagnostics.
718 This bug affects threaded version of GFS server.
720 --- 2.0.18 2004/03/20
722 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
725 Ensure zlib.dll is packed with Windows install.
727 --- 2.0.17 2004/03/17
729 Fix encoding of xsd:string to use text instead of CDATA.
731 Fix endless loop in CQL parser with unbalanced ".
733 Use a more compact way to store MARC-8 conversion tables.
735 --- 2.0.16 2004/03/16 Debian only
737 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
740 Update CQL parser to use new CQL 1.1 modifiers for booleans and
745 --- 2.0.15 2004/03/01
747 Another fix for decoding of XML packed records.
749 --- 2.0.14 2004/02/25
751 Fixes for Chunked encoding. White space not ignored after length spec.
753 Update NS and use default NS for SRW diagnostic elements.
755 --- 2.0.13 2004/02/23
757 Implement ZOOM_resultset_cache_reset which resets record cache.
759 Implement ZOOM_resultset_sort which sorts a result set.
761 Implement chunked HTTP transfer.
763 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
765 --- 2.0.12 2004/02/16
767 Added member 'schema' to bend_explain_rr structure so that backend
768 can specify explain record identifier. Defaults to Zeerex 2.0.
770 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
772 --- 2.0.11 2004/02/16
774 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
777 Added init command for yaz-client which sends "extra" init request.
779 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
780 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
782 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
784 Make ZOOM error code for "invalid query".
786 Fixed compilation for SSL which wasn't properly enabled for all platforms.
788 --- 2.0.10 2004/02/05
790 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
793 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
795 Added option -p <file> to make Generic Frontend Server to write PID file.
797 Added option -D to put Generic Frontend Server in background on its own.
799 Make ZOOM C recognize option "password". If unset, "pass" is used
800 (for backwards compatibility).
802 Fixed a bug in Generic Frontend Server that could make it crash if a
803 client sets characterSetNegotation bit, but didn't pass negotiation stuff
806 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
807 Must be issued before open, in order to be in effect.
809 --- 2.0.9-6 2004/01/12 Debian/Windows
811 Make the SRU server more picky WRT unknown params, etc.
813 Bug fix: ZOOM scan response didn't return displayTerm - when present.
815 New YAZ client command, options, that sets Z39.50 options.
817 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
818 options from a string of tokens (one token for each option bit).
820 Update SRW diagnostic code messages.
822 --- 2.0.9-5 2004/01/07 Debian/Windows
824 Handle user defined stylesheet for SRW/SRU.
826 --- 2.0.9-4 2004/01/06 Debian/Windows
828 Fix bug in decoding of Content-Length.
830 --- 2.0.9-3 2004/01/06 Debian/Windows
832 Fix a bug with decoding of XML packed records.
834 --- 2.0.9-2 2004/01/05 Debian only
836 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
838 Fix bug in SRW/SRU diagnostics decoding.
842 Fixed bug in Generic Frontend Server which could drop records exceeding
843 preferred message size. Reported and fixed by Irina Dijour.
845 Fixed calculation of package size for structured records in Generic
846 Frontend Server. Reported and fixed by Irina Dijour.
848 Fixed namespace for SRW/SRU diagnostics.
850 Fixed SEGV in yaz-client that occured for HTTP connection errors.
854 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
855 this version is incompatible with version 1.0 and older YAZ SRW/SRU
858 CQL changes to reflect recent changes to the specification:
859 * Documentation talks about context sets instead of index sets.
860 * Documentation talks about indexes instead of qualifiers.
861 * The CQL-to-PQF transformer's configuration file now uses
862 "index.set.name = <attributes>" instead of the old form
863 "qualifier.set.name = <attributes>". (Both forms are still
864 understood but the latter is deprecated.)
865 * CQL terms with no explicit index specified are now interpreted as
866 cql.serverChoice instead of srw.serverChoice (which of course
867 behaves exactly the same.)
871 MARC conversion can now generate ISO2709 output in another
872 character set. yaz-marcdump uses this facility if you invoke it
875 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
876 functions from there can be used from C++.
880 Frontend server now transfers memory from decoded packages to stream
883 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
884 references to show up.
886 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
887 the ZOOM Abstract API. The older names for the same options are still
888 also supported for the benefit of old applications.
890 ZOOM-C supports "implementationId" and "implementationVersion" options
891 to go along with "implementationName". These allow the user code to
892 specify identification strings to be sent to servers.
893 Add OID for the new ExtLite attribute set.
895 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
896 as requested/supplid by Ere Maijala <ere@atp.fi>
898 For generic frontend server, reverse the order of
899 "toolkit-supplied / application-supplied" strings sent as implementationId,
900 Name and Version. Also, remove the spaces around the slash. This brings
901 the GFS in line with the behaviour of ZOOM-C on the client side.
903 Add function ZOOM_scanset_display_term.
905 yaz-client shows scan displayTerm if present.
907 Utility yaz-iconv is now installed by default along with the man page
910 Extend configure check for OpenSSL to use pkg-config where available (such
913 Incorporate patch by Morten Bogeskov which allows a Unix file socket
914 server to specify uid/gid/mask for socket using the format
915 unix:[user=uid,][group=gid,][umask=mask,]file=path
916 If file= is omitted the existing format is assumed, e.g.
918 in which case the mask is 0666 (rw for everybody).
920 Major restructure of YAZ source. All source in libyaz is in src directory.
921 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
922 util (utility programs such as ASN.1 compiler, yaz-marcdump).
924 Added man page for utility yaz-marcdump (used to be called marcdump).
925 yaz-marcdump is installed by 'make install'.
927 Fixed a memory leak in Generic Frontend Server that occurred when decoding
928 of incoming package failed.
930 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
932 Change prototype of odr_perror: add const to message string.
934 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
936 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
937 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
938 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
939 DNS lookup. There should not be any compatibility problems with this
940 assuming that blocking=1 or 0 is used.
942 Fix bad reference in UNIX comstack in function cs_addrstr.
944 Fix for compilation on AIX.
946 The generic front-end server (server/seshigh.c) now supports returning
947 Init diagnostics to the client in User-information-field, in
948 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
953 Allow any CQL relation (not just all,any,exact,scr).
955 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
956 that features the same UI.
958 Implemented command update0 in YAZ client which is equivalent to
959 update but uses old of Ext Update ASN.1.
961 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
962 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
963 Previously no OID was used for this info.
965 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
966 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
967 returns 'malformed search term' otherwise.
969 SortResponse member resultCount now set to NULL in sort handler of
972 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
975 Add three new utility functions for translating OIDs between various
976 formats -- symbolic name such as "Usmarc", minus-1-terminated int
977 arrays and dotted strings such as "1.2.840.10003.9.5.1":
978 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
979 char *oid_to_dotstring(const int *oid, char *oidbuf);
980 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
982 Reverted modifications for ES Update definition for z_IU0Update
983 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
984 is back to YAZ 2.0.2.
986 String value attributes for CCL parser.
988 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
989 which their FirstSearch server returns in Init responses, sometimes
990 carrying useful diagnostic information when Init fails. This has the
991 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
992 "z39.50/oclcui.asn", where its definition is somewhat different from
993 what OCLC document on their web-site, as required to interoperate with
996 Support for anonymous authentication in yaz-client. Use the command
999 * Fix the OID of the Index Data-local "admin" Extended Service from
1000 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1001 the 1000, which indicates a locally-defined OID, was a mistake.
1003 --- 2.0.3 2003/06/20
1005 Fix CCL directive @case handling so that it affects string match for
1006 both CCL keywords and qualifiers.
1008 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1009 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1010 Decoder has been updated with ASN.1 changes as listed in
1011 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1012 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1013 z_IUUpdate, remains unchanged.
1015 ZOOM_record_get may now return a record in a specific character set.
1016 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1017 "from" is the character set of record as returned by target. "to" is
1018 the character set to be returned. If omitted, "to" is UTF-8.
1020 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1022 New ODR utility, odr_getelement, which returns name of element for
1023 which encoding/decoding failed.
1025 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1026 in cases where a required element was omitted.
1028 Bug fix: some MARC8 sequences were not converted.
1030 New ZOOM option "step" which specifies number of records to be
1031 retrieved in one chunk. Used in conjunction with "start" and "count".
1033 SRW support for yaz-client. Use scheme http: to use it, e.g.
1036 yaz-client no longer does (un)intelligent character set conversions
1037 by default. Can be enabled with charset and marc_charset commands.
1039 xmalloc trace fix for 64-bit systems such as DEC alpha.
1041 Solaris 2.6 compile fix.
1043 New function, cql_strerror() translates SRW error codes, as returned
1044 by cql_transform_error(), into human-readable English strings. Used
1045 in yaz-client diagnostics when appropriate.
1047 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1048 converts it into a type-1 query which is sent to the server. This
1049 makes CQL available for use with all Z-servers, as opposed to the tiny
1050 minority that can handle CQL queries themselves.
1052 --- 2.0.2 2003/04/28
1054 New Debian package layout similar to the Redhat Package layout.
1056 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1057 and search result respectively.
1059 --- 2.0.1 2003/04/25
1061 Redhat package is now several packages: libyaz (runtime libraries),
1062 libyaz-devel (development and documentation, and yaz (utility programs).
1063 Package spec file by Morten Bøgeskov.
1065 New member 'schema' in struct bend_fetch_rr which the name of requested
1066 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1067 handler MAY set this to reflect the schema of the returned record.
1069 New member 'display_term' in struct scan_entry. GFS now sets member entries
1070 and allocates scan entries to be filled by user scan handler. In previous
1071 version, entries member was allocated by the scan handler. That still works,
1072 but the GFS will ignore member display_term - assuming it was NOT set by
1073 the handler. The fact that the GFS now allocates the entries both allows
1074 for new members and makes a scan handler easier to write.
1076 Fix CQL lex buffer overflow.
1078 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1079 SRU default recordPacking is string.
1081 SRU protocol support for frontend server.
1083 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1085 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1087 Added scan for the ZOOM shell (zoomsh).
1091 * String Identifers for Schemas (Amendment 5).
1092 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1093 Old definition for schema
1094 Odr_oid *schema; /* OPT */
1099 Z_InternationalString *uri;
1100 #define Z_Schema_oid 1
1101 #define Z_Schema_uri 2
1104 * resultCount parameter to Sort Response (Amendment 1).
1105 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1107 Support for SRW 1.0 over HTTP. This is an optional feature and
1108 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1111 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1112 on the same port. SRW SearchRetrieveRequests are mapped
1113 to bend_init,bend_search,bend_fetch,bend_close.
1115 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1117 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1118 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1120 ZOOM connections are SRW based if schem http is used for hostname
1121 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1122 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1124 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1125 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1126 distance=n, order=true/false, relation=le, prox unit=word. If
1127 n is omitted, distance 1 is used.
1129 Fixed problem with C compiler include path in wrong order.
1131 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1132 on Solaris. Patch from Ko van der Sloot.
1134 New MARC decode API. All new functions operate on a yaz_marc_t
1135 handle. The most important new functions are: yaz_marc_create,
1136 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1137 decode and destroy respectively. Decoder can produce formats
1138 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1139 include/yaz/marcdisp.h.
1141 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1142 to UTF-8, UCS-32, wchar_t or Latin-1.
1144 * Prototypes for yaz_iconv_-functions moved to separate header
1145 include/yaz/yaz-iconv.h.
1147 Make a few private functions 'static' in unix.c. This prevents
1148 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1150 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1151 are set when Init Response is received.
1153 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1154 but returns diagnostic set as well.
1156 New function yaz_strerror which is a portable wrapper for
1157 strerror/strerror_r/GetLastMessage.
1159 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1160 is returned for MARC. If type is "oai", then OAI MARC is returned.
1162 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1165 --- 1.9.2 2002/11/26
1167 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1169 Fix bad race conditions on SIGTERM and terminate gracefully in
1172 Move retrieval (data1) module to Zebra since nobody seems to be
1175 Add GRS-1 render for ZOOM using same format as yaz-client.
1177 --- 1.9.1 2002/10/05
1179 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1181 Fix broken ESpec handling in data1 module.
1183 SGML reader parses comments and makes them part of the data1 tree.
1185 Added several type casts so that YAZ compiles as C++ code.
1187 ZOOM didn't handle PDU encoding failures properly.
1189 Added more Bib-1 diagnostics (approved extensions).
1191 GNU configure: better check for iconv.
1193 More portable use of accept, getpeername. Check for socklen_t. Use
1194 int/size_t if socklen_t is not defined.
1198 PQF parser rejects bad queries - including those with extra
1199 characters in them. PQF parser used to silently ignore that.
1200 Cleaner API for PQF added, which allows you to get detailed
1201 error information for bad queries (see yaz/pquery.h).
1203 Fixed bug in ZOOM_record_get for type "database".
1205 Implemented mini iconv library supporting conversions between
1206 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1208 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1210 --- 1.8.9 2002/08/20
1212 Fixed ZOOM C record cache so that preferredRecordSyntax and
1213 elementSetName is used to check for already fetched records.
1215 --- 1.8.8 2002/08/02
1217 Added three members in bend_initrequest structure to facilitate
1218 character set negotiation.
1220 Fixed a bug in frontend server that could cause indefinite
1221 loops under rare conditions.
1223 Revised character set utilities (charneg.h) so that encoding
1224 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1226 For PQF, directive @term <type> sets term type for Scan/Search.
1227 Here <type> is general, string, numeric, null. The term type
1228 is inherited - just like @attr.
1230 New call odr_set_charset that sets character set conversion for
1231 international-strings on a ODR stream. Prototype is:
1232 int odr_set_charset(ODR o, const char *to, const char *from);
1233 The InternationalString is still represented as C string in YAZ
1234 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1235 won't). On the protocol level, you can use any encoding.
1237 Support for UNIX sockets in ZOOM.
1239 Solaris recv sometimes returns errno == ENOENT. It is treated as
1240 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1242 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1243 both client and server. Code by Morten Bøgeskov.
1245 --- 1.8.7 2002/05/22
1247 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1248 that they can be used directly from Visual Basic. You must recompile
1249 your windows APP if you're using ZOOM.
1251 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1252 Commands "lang" and "charset" sets language and character set respectively.
1253 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1254 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1256 Attributes from multiple CCL fields may be OR'ed rather than merged
1257 using directive "@field or". Fields are still merged by default -
1258 equivalent to "@field merge".
1260 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1263 Fixed bug in zget for parameter ExtendedServicesResponse.
1267 --- 1.8.6 2002/03/25
1269 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1271 Client displays USR.1:SearchResult-1 (hits per term).
1273 Additional Search Info for search in Generic Frontend Server.
1275 Fixed CCL parsing of "field=s".
1277 WIN32 installer - using the excellent NSIS software from nullsoft.
1279 Fixed CCL parsing of "field = - <number>".
1281 Added function yaz_marc_decode that decodes MARC for line mode
1282 display or XML (similar to that used by JZKit).
1284 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1285 Z39.50. But ISO/ILL was, however.
1287 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1288 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1293 --- 1.8.5 2002/02/03
1295 New YAZ client features: Command completion and new commands:
1296 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1297 Code provided by Jacob Poulsen.
1299 New call oid_trav, that visits all registered OIDs via callback.
1301 Function ZOOM_record_get now returns const char pointer rather than
1302 void pointer. It saves a lot of type casts.
1304 For YAZ client, command "auth" now allows you to set authentication
1305 in IdPass style. It is enabled when three tokens are given - order
1306 is user, group and password.
1308 Fix memory leaks in MARC record handling for ZOOM.
1310 New option for YAZ client, -k <kilobytes> that sets
1311 maximum record size. Similar to -k option for generic frontend
1312 server and yaz-ztest.
1314 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1316 Prefix query parser reports "fail" when bad attribute set is given.
1318 Fix in MARC decoder. Proximity logging. Fix for attribute set
1319 in scan handler for server. Patches by Shigeru Ishida.
1321 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1324 Configure option --with-openssl=<dir> now works when a directory is
1325 specified. Patch provided by Morten Bøgeskov.
1327 New option for YAZ client, -u <auth>, that sets authentication.
1329 ZOOM fix: error information was sometimes "missing", since error
1330 was cleared/reset too when it shouldn't.
1332 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1334 --- 1.8.4 2002/01/04
1336 Scan for ZOOM API. New object ZOOM_scanset. New functions
1337 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1338 ZOOM_scanset_destroy.
1340 New ZOOM function, ZOOM_connection_last_event, that returns type
1341 of last event (such as "receive data", "send data", "apdu received",
1344 New ZOOM option, schema, that specifies schema for retrieval.
1346 New CCL feature. Qualifiers can be aliases for one or more
1347 other qualifiers (if more than one is given, OR is used).
1349 ZOOM uses named result sets if target supports it.
1351 Two new YAZ client commands: . (dot, which sources a script of YAZ
1352 client commands), and ! (to execute shell command.). Implemented
1355 Working on Debian packages.
1357 --- 1.8.3 2001/11/19
1359 YAZ client enables named result sets only if target supports it.
1361 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1363 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1364 with key="host" to get same result.
1366 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1367 Function Z3950_resultset_record(s) returns references to records
1368 "owned" by resultset. To become owner use Z3950_record_clone.
1370 Function z_ext_record handles Extended Services. Thanks to
1373 --- 1.8.2 2001/11/12
1375 CCL Parser fix: ignore token comma when dealing with and-lists.
1377 Documentation updates for COMSTACK.
1379 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1380 Changed prototype Z3950_records. For some functions, int parameters
1381 were changed to size_t.
1383 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1386 New MARC decode/display function, marc_display_exl, which properly rejects
1387 non-ISO2709 records. YAZ client uses it.
1389 --- 1.8.1 2001/10/29
1391 Fix bug: local attribute set wasn't set correctly in PQF strings.
1395 * Old Z39.50 codecs no longer supported.
1397 Added ZOOM C binding. See http://zoom.z3950.org/
1399 Renamed states for COMSTACKs to avoid confusion with events.
1401 Implemented cs_look and proper cs_rcvconnect.
1403 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1405 Configure detects POSIX threads on OpenBSD.
1407 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1408 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1410 When error is returned from present handler, non-surrogate diagnostic
1411 is returned in present response (and fetch handler is no longer called).
1413 * Minor adjustments to pquery parser (PQF). Token characters may be
1414 escaped by using backslash (C-style).
1416 PQF parser allows string attribute values to be specified. For @attr,
1417 non-numeric characters after the equal-sign are treated as strings
1418 (e.g. @attr 9=title).
1420 CCL trunction character may be defined (@truncation in file)
1422 * function zget_ExtendedServicesRequest sets waitAction to
1423 waitIfPossible (was wait).
1425 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1428 CCL operator names may be set in field definition files (CCL_bibset).
1429 See ccl/bib1 for an example.
1431 Fixes in ASN.1 compiler for C++ compatibility.
1433 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1434 and "op_or" to avoid conflict with C++.
1436 Fixed problem with GNU readline detection on Redhat 7.0.
1438 Added step-size for Scan backend handler.
1440 Fixed bug that made the frontend server crash when no attribute
1441 set was specified for scan.
1443 Front-end server automatically switches to original working directory
1444 when installed as an NT service. Previously -w had to be specified to
1447 Added extended attributes for retrieval module (data1), so that data1
1448 records carry d1_readXML/SGML attributes. d1_read also supports
1449 null-data rules ( <tag/>)
1451 On UNIX when POSIX threads are available, a separate library libyazthread
1452 is created. Programmers should link with that library and the yaz library
1453 when using threads. The reason for the split was that some applications
1454 on Linux, such as Apache, doesn't work well when using shared objects that
1457 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1458 (or any frontend server) in SSL mode by specifying ssl: followed by
1459 address. Only tested on UNIX.
1461 Added feature for CCL module. Virtual structure s=al or s=ol generates
1462 and-list and or-list respectively instead of phrase search.
1466 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1467 log_mask_str. This was done to avoid name conflicts with other libraries
1468 (such as other PHP extensions).
1470 Added raw OID member for preferred record syntax (request_format_raw)
1471 and returned record syntax (output_format_raw) for backend fetch method.
1473 Config file yaz-config now accepts options so that it returns specific
1474 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1476 Shared library support for UNIX using GNU libtool.
1478 * Modified backend interface. Request/Response struct's replaced by
1479 one read/write C struct. For example bend_fetchrequest and
1480 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1481 Every handler - even search has to be registered in bend_init
1482 handler. This means that the YAZ library no longer refers to
1483 external functions and it makes it possible to make the whole
1484 thing a single DLL/SO.
1486 Added Segment handler for backend server.
1488 Added Zmbol/Zebra administrative functions to YAZ client.
1490 Threaded frontend server on UNIX (when POSIX Threads are available).
1491 Starting the server with option -T enables multi-threading.
1495 Added configure option --enable-comp/disable-comp to control use
1496 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1497 located in sub directory asn.
1499 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1500 in ${exec_prefix}/bin along with the other programs yaz-client and
1503 GNU automake used to maintain makefiles.
1505 Added several OID's.
1507 Changed retrieval module so that we can load records with no abstract
1508 syntax defined. Tagpaths in these records are fully composed of string
1511 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1515 On UNIX, the generated makefile now supports a proper 'make install'.
1516 The prefix can be set via GNU configure to set the install location
1517 (default is /usr/local).
1519 * YAZ programs client and ztest were renamed to yaz-client and
1520 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1521 locations, such as /usr/bin,/usr/local/bin,etc.
1523 * YAZ Header files were moved from include to include/yaz. YAZ Header
1524 files are referred to as include <yaz/log.h> rather than <log.h>.
1525 The YAZ include path (-I ..) is therefore the same as before. Programmers
1526 should update their #include statements or use -Ipath/include/yaz
1527 instead. The main motivation for doing this change is that YAZ header files
1528 can be installed in "standard" locations /usr/include,/usr/local/include
1529 without introducing conflicts, since ALL YAZ header files are stored
1530 in subdirectory yaz (under /usr/include for example).
1532 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1533 rather than project/workspace files. We switched because project files
1534 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1537 Changed name of logging function, logf, to yaz_log, to prevent name
1538 clash with some math-log functions. The YAZ header log.h defines logf
1539 to yaz_log (#define) so there should be no incompatibilities by this
1542 Added bend_start/bend_stop handlers for server. These handler are
1543 called on start/stop of server. For windows they are called whenever
1544 a service is started/stopped.
1546 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1547 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1548 in util/yc.tcl. The auto-generated C code structures are, in a few
1549 cases, incompatible with the old decoders. There are differences in the
1550 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1551 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1552 The preprocessor variable ASN_COMPILED is defined when the compiled
1553 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1554 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1555 wish to use the old encoders/decoders you can specify --disable-yc
1558 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1559 version so that it supports both new - and old version of DB Update
1561 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1562 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1563 change. The name parameter can be set to 0 in which no name is specified
1564 for the construction. The macros odr_implicit and odr_explicit sets name
1565 parameter to zero for the construction involved. New macros
1566 odr_implicit_tag and odr_explicit_tag are similar to the others,
1567 except that a name parameter is added. For programmers' that don't use
1568 ODR they probably only need to change the call to z_APDU and z_External.
1570 Added access control facility by interfacing the TCP wrapper library.
1571 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1572 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1573 name of the daemon and enables the access control as specified in
1574 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1576 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1577 den Dool <H.M.vdnDool@kub.nl>.
1579 Added reference ID parameter to most functions in server API - refer
1580 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1582 Changed name of ccl library to libccl.a (was ccl.a).
1584 Fixed bug in decoder for Explain (Category TargetInfo).
1586 Added support for GNU readline in client. Thanks to Jacob Poulsen
1587 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1589 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1590 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1591 IMPLEMENTATION! This change was made to the development version before
1592 the ZIG decided to retract the amendment. If any users MUST be
1593 compatible with the original Update definition, PLEASE CONTACT US, and
1594 we will include a separate definition corresponding to the old Update
1595 ES. Note that because of the change to the ASN.1 of the
1596 TaskPackageRecordStructure we cannot define a single structure that
1597 will support both versions.
1599 * Added const modifier to buffer parameter for some ODR/BER encoding
1600 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1601 completeWAIS, odr_dumpBER.
1603 Fixed bug in client.c which caused a crash when a scanResponse didn't
1604 contain positionOfTerm.
1606 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1607 * will cause an error in a client if a non-YAZ target sends both a
1608 * list of Scan entries and non-surrogate diagnostics.
1610 Retrieval module enhancements. Tag sets may be typed in the reference
1611 to it. From the .abs-file the "tagset" directive takes a third optional
1612 integer type for the tag set referenced. From a .tag-file the "include"
1613 directive takes a third optional type as well. The old "type" directive
1614 in the tag set itself is still recognized but acts as the default type
1617 Backend interface change. Individual Scan terms returned from bend_scan
1618 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1619 in include/backend.h.
1621 Retrieval module enhancements. Multiple tag sets and attribute sets may
1622 be specified in abstract syntax specs. Revised the error/warning for
1623 logging messages reported by the retrieval module when reading the
1626 Object Identifier system (oid_..) changed. The API is backwards
1627 compatible but the oid-routines now allocates new OID's when needed.
1628 Raw OID's may be specified in oid_getvalbyname.
1630 YAZ now uses GNU configure to generate Makefile(s).
1632 * Minor changes in some of the member names of DeleteResultSetRequest and
1633 DeleteResultSetResponse. See include/proto.h.
1635 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1636 and added member 'languages' in TargetInfo (which was missing).
1638 Changed the way attribute sets are handled in the retrieval
1639 module. These are now cached, just like the abstract syntaxes
1642 Changed YAZ so that it links with compiled ASN.1.
1644 Added Explain-schema definitions and mapping routines. The following
1645 Explain categories have been implemented: AttributeDetails,
1646 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1648 Fixed minor bug in Windows version of Server Library.
1650 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1652 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1654 Added EXTERNAL: UNIverse Resource Report (non-standard).
1656 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1657 ENUMERATED and SET OF.
1659 * Added 'const' to some of the char pointer arguments for the
1660 functions, data1_read_node, data1_getelementbytagname,
1661 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1664 Fixed bug in data1_insert_taggeddata - the last_child member of
1665 parent wasn't initialised.
1667 * Changed data1_read_record and data1_read_node so that the supplied
1668 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1669 doesn't refer to any parts of the "SGML"-buffer.
1671 Fixed bug in server library (Windows version of statserv_remove).
1673 * Changed code so that it compiles as C++. The type definition
1674 of Odr_fun which is a member of Odr_arm was changed. The result is,
1675 that an explicit typecast is needed for the fun pointer when
1676 using Odr_arm - as in:
1677 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1679 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1681 Implemented the new structured date and time definition as approved
1682 by the ZIG. Added schemaId element to the specificTag in Espec-1
1683 (also approved at the last ZIG). Thanks to RVDM.
1685 Added some Object identifiers (RVDM).
1687 Changed the Update Extended Service (RVDM).
1689 Added command "refid" to client which specifies referenceId for
1690 the following requests.
1692 Implemented extended service handling for server. See ztest.c
1693 for an example as well as backend.h. New handlers are registerd
1694 in the Init handler.
1696 * Changed interface for sort in server.
1698 Added new members to statserv_options_block. It allows a server
1699 to read options from another source than just the command line. Thanks
1700 to Charles Woodfield.
1702 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1703 renamed to zboolean. Some C++ compilers complained about the name.
1705 Minor changes to gils.abs. Added index 's' (sort) on title
1706 and date/time-last-modified.
1708 --- 1.4pl2 1998/1/30
1710 Fixed bug in server library regarding inetd mode (-i). This bug
1711 was introduced by release 1.4.
1713 --- 1.4pl1 1998/1/29
1715 Added sort facility in client and backend server interface.
1717 Fixed problem with dependencies in Makefile(s).
1719 Fixed bugs for encoders/decoders of extended services and
1722 Implemented sub-tree feature for schemas. Sub-trees are
1723 referenced in *.abs-files. See explain.abs for an example
1724 of the use of this feature.
1726 Modified bib1.att; local attributes for ANY didn't include
1727 ANY itself (only affects use of the retrieval module).
1729 Fixed bug in plain SGML reader in function data1_read_node:
1730 tags with prefix "var" was incorrectly interpreted as variants.
1732 Added feature "sub-schemas" to enable references to - and definitions
1733 of - group of elements.
1735 * Removed member parent from type data1_element (in data1.h).
1737 Implemented function odr_nullval() that returns the value of
1740 * Removed member num_children from data1_node (in data1.h).
1742 Made NT service interface part of the server library. The
1743 function statserv_main uses the NT service when required and
1744 calls the statserv_start / statserv_close routines.
1746 Routine zget_SearchRequest and zget_PresentRequest fills
1747 resultSetName/Id member with "default" instead of "Default".
1749 Fixed memory leak in server. Request queue member wasn't freed.
1751 Fixed nmem_exit so that memory is freed.
1755 Revised the CCL parser utility to be thread safe.
1757 Added function, oid_ent_to_oid, to replace the function
1758 oid_getoidbyent, which is not thread safe.
1760 * Added nmem_init and nmem_exit to initialize and release
1761 NMEM resources. Function nmem_init should be called once in the
1762 initial thread before NMEM/ODR is used. statserv.c and client.c
1763 have been changed accordingly. The change was necessary to make
1764 NMEM thread safe. The NMEM memory pool is shared amongst threads
1765 in a process. Unix-based applications will still work fine without
1768 Added NT Services interface for the the Z39.50 (statserv) Server.
1769 Refer to the ztest.c source on the usage.
1771 Windows 95/NT port using MSVC5.0. Project files are included in the
1774 * Defined new 'global' handle for the retrieval (data1) system. The
1775 new handled, data1_handle, describes the state of the data1 system.
1776 This handle is passed as first argument to virtually all
1777 data1 related routines. The functions data1_create and data1_destroy
1778 creates and destroys a data1 handle respectively.
1780 Added ODR encode stream member to all backend request structures
1781 init, search, scan etc. This stream should be used to allocate all
1782 memory used for the response when thread safe operation is needed.
1784 Changed the comstack utility, cs_addstr, to be thread safe. The
1785 returned hostname string returned by the function is now part the
1788 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1789 function. The cs_straddr takes a COMSTACK handle as argument, so this
1790 function must be used after cs_create and before bind/connect.
1791 This function is thread safe.
1793 Moved test server to 'ztest' directory - generic server code still
1794 in 'server' directory.
1796 Made prefix query (pquery.c) utility thread safe.
1798 Added new function modifier YAZ_EXPORT to 'export' public DLL
1799 functions when using windows (see include/yconfig.h).
1801 Added definitions to the OID database (util/oid.c) (RVDM).
1803 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1805 Added call to ccl_rpn_delete in client program.
1807 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1808 release of RPN structure.
1810 Added support for C++, headers uses extern "C" for public definitions.
1811 With input from RVDM.
1813 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1814 Thanks to Ronald van der Meer (RVDM).
1816 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1818 Added support for private extensions to the OID database
1819 (oid_setprivateoids()). Thanks to RVDM.
1821 Added optional, physical ANY (key replication)
1823 Fixed null-reference problem in GRS-1 output filter.
1825 Proximity operator added to Prefix Query Format (PQF).
1827 In test client command "base" accepts multiple databases.
1829 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1833 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1835 Smallish bug-fixes in the new encoders/decoders (explain).
1837 Bug fixed in DeleteRequest.
1839 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1841 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1843 Added SOIF syntax (using private OID for now) to retrieval module and client.
1845 Added Update extended service.
1847 Added SearchResult-1 additional info structure.
1849 Added optional CCL (ISO8777) interpreter as separate module. Available
1852 --- 1.2 1996/6/10 (1st anniversary release)
1854 Added Summary record syntax. Lightly tested.
1856 Added OPAC record syntax. Untested.
1858 Added ResourceReport service encoders/decoders. Untested.
1860 Fixed bug in z_Unit - wrong tagging on unitSystem.
1862 Fixed bug in the DiagRecs decoder.
1864 Added options for max PDU size and session timeout to frontend-server.
1866 Added documentation of query-language parsers and other supporting utilities.
1868 [frontend-server] Added Attribute set to the bend_scanrequest API.
1870 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1871 surrogate diagnostics were generated.
1873 [retrieval] Allow multiple local values for attribute.
1875 [retrieval] Allow multiple attributes per element in .abs files. index type.
1877 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1879 --- 1.1pl2 1996/4/10
1881 Minor changes, mostly specific to Zebra's requirements (retrieval)
1885 Repaired bug in frontend server when running multiple listening
1886 endpoints in dynamic mode.
1888 z_External() now won't break if a known, ASN.1 value comes encapsulated
1889 in an octet-string. The value will pass through unmodified in an Odr_oct.
1891 Added a bit of code to the demo client to decode & display
1892 ASN.1-structured records represented in the octet-aligned branch of
1893 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1895 Added z_ext_getentbyref() to the ASN module. Doc updated.
1897 * Completed the SCAN definition in the ASN module. This may break SCAN
1898 code based on older YAZ-versions at compile-time. The fix is easy -
1901 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1902 under the SCAN definition. Remember to initialize this, server-people.
1904 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1905 that this does not extend to ODR and ASN.
1907 Comstack allows insertion of established socket (primarily for
1908 inetd-operation of servers). Doc updated.
1910 Front-end server can now start from the inetd in TCP mode. Doc
1913 --- 1.0pl4 1996/1/24
1917 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1918 the rank and record number.
1920 Adjustments to the frontend server.
1922 Fixed diagnostic BER dumper. It ignored the file argument.
1926 Various changes to retrieval module.
1928 Changed the union discriminators of the protocol files from enums to
1929 ints paired with #defines.
1931 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1934 *Changed operator in the RPN structure to 'roperator', again to avoid a
1937 Fixed problems in Explain decoders/encoders.
1939 --- 1.0pl2 1995/12/6
1941 Memory bug in log module fixed.
1943 --- 1.0pl1 1995/12/5
1945 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1947 Bug in Explain DatabaseInfo module fixed.
1949 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1953 The shift to v1.0 signals that we now consider the *core* functionality
1954 of YAZ reasonably stable (the core being more or less equivalent to
1955 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1956 tested (Explain not at all - though that will happen soonish).
1958 Minor changes to code to support Windows port.
1960 Various minor changes after we're getting to use GRS-1 & co. more.
1962 Added Espec-1 format.
1964 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1965 of the protocol and it cannot be selected when encoding (maps into 'string'
1966 when decoding). Needed to talk to some servers.
1968 Demo client can request simple element set names.
1970 Added Diagnostic Format encoders/decoders.
1972 Added simple Close handling to frontend server (no hooks for resource
1973 reporting yet), and demonstration client.
1975 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1977 --- 1.0b3 1995/08/24
1979 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1980 handled incorrectly when records were requested in the searchResponse. This
1981 will only affect you if you use the frontend-server.
1983 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1984 Test-client will ask for and print GRS1. Ztest will return dummy records
1987 Added Explain encoders/decoders to the service-level API. Untested.
1989 Added Extended Services: Item Order encoders and decoders to the Service-
1990 level API. Untested. We could use a recent copy of the pertinent bits
1991 of the ILL protocol to add those bits.
1993 Added diagnostic format 1 encoders/decoders to the service-level API.
1996 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1997 odr_cons.c, which causes a more correct output.
1999 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2000 was always set to 0 when no records were requested in the searchRequest.
2002 * Added better external-handling. This shouldn't harm old code that
2003 *encodes* externals. It can break code that looks for a
2004 'single-ASN1-type' representation, since those types that are known
2005 are now decoded immediately. Look at the SUTRS sample code in
2006 seshigh.c and client.c. Documentation updated.
2008 Handling of structured records in bend_fetchresponse. Length -1 marks
2009 structured record, type is deduced from format field.
2011 --- 1.0b2 1995/06/27
2012 Fairly quick maintenance release to add SUTRS support.
2014 Fixed handling of SUTRS records in the demonstration client.
2016 * Added format field to the bend_fetchrequest and bend_fetchresponce
2017 structures of the backend API (frontend server). When the record is
2018 returned, the value of the format field is mapped to an OID. The
2019 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2020 of the record. The special value VAL_NONE in the bend_request means
2021 that no specific format was requested by the client. Documentation
2022 updated accordingly. Test server (ztest) will return a fixed dummy
2023 SUTRS record if your client requests SUTRS.
2025 Documentation updated accordingly.
2027 You can now set external libraries and RANLIB support in the top-level
2031 First public release.
