2 Extended ZOOM result set options with two options that may be read by
3 a client: resultSetStatus and presentStatus with values as specified for
5 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
7 Fixed bug #827: Using SSL fails on Debian etch.
9 Fixed bug #826: Weird looking chars for set of MARC records.
11 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
12 that is treated as an ItemOrder with itemRequest being an XML document
13 external. The value of "doc" is the content.
15 Extended the GFS search facility. New member of bend_search_rr
16 'estimated_hit_count' signals that hits is known to be an estmate
17 (higher or lower than real hit count). New member 'partial_resultset'
18 signals that the search was partial (hit count is lower or equal than
19 real hit count). For Z39.50, the information is stored in resultSetStatus
20 member of SearchResponse APDU. For SRU, the information is signalled
21 via SRU diagnostic 59: "Result set created with valid partial results
24 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
28 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
30 Added ZOOM_connection_peek_event.
32 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
33 the following new functions:
34 ZOOM_event_nonblock, ZOOM_connection_process,
35 ZOOM_connection_get_{socket,mask,timeout},
36 ZOOM_connection_fire_event_{timeout,socket}.
37 The existing blocking event handler, ZOOM_event, is a wrapper for the
38 + blocking ZOOM_event_sys_{poll,select}.
40 Implemented function ccl_xml_config which parses XML version of CCL
41 configuration (bug #798).
43 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
45 Added timings utility (yaz/timing.h)
49 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
52 Fixed bug #779: Rotation of apdu.log fails.
54 Fixed for character set conversions:
55 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
56 Honor G1 set in MARC-8 decoding.
60 Fixed bug #775: char conversion does not handle Alternative UTF-8
63 Implemented function yaz_marc_read_line which parses MARC line format
64 records. There is a wealth of formats out there. So far, this function
65 reads line records produced by yaz_marc_write_line.
67 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
68 more generic and easier to remember(!) options: -i format and -o format
69 which specifies input format and output format respectively - where
70 format is one of "marc", "marcxml", "line", "marcxchange".
72 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
73 does not print anything except warnings for records.
75 For yaz-marcdump, added support for MARC split into files (-s) with a given
78 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
79 spec, at http://www.loc.gov/standards/sru/record-update/
80 This has changed the binary layout of the following structs:
81 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
82 bend_update_rr . Patch by Ko van der Sloot.
84 Added GFS utility function bend_assoc_is_alive which returns 1 if
85 association is still alive (client is connected); 0 otherwise (client
86 closed connection). This allows busy servers to stop working for
89 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
90 been a separate piece of software. This version of ziffy has been modified
91 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
93 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
95 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
96 Client code may now interrogate options such as "init_opt_sort" to
97 find out whether the server claims to support various options.
101 Added utilities yaz_{set,get}_esn to set/get element set name from
104 Removed the build of libyazthread.la. The libyaz.so is the threaded version
105 of YAZ and has been so since YAZ 2.1.10.
107 Implemented ZOOM_record_error which returns error information for
108 record (surrogate diagnostic).
110 --- 2.1.38 2006/10/31
112 Updates for SRU Update by Ko van der Sloot:
113 1. Changed name from "operation" to "action"
114 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
115 versions in the code, marked as 'backward compatible'.
116 3. Added diagnostics for SRU Update.
118 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
120 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
122 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
124 For GFS, fixed problem with SRU diagnostic 'First record position out of
125 range' being issued for 0 hits.
127 zoomtst10 part of Windows Build.
129 --- 2.1.36 2006/10/13
131 Implemented yaz_filepath_comp which splits a path into file path
132 components (required by Zebra 2.0.3+).
134 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
135 BSD inspired license until now so this should not have any real impact on
136 anybody. See http://www.opensource.org/licenses/bsd-license.php
138 Fixed bug #687: Missing log lines.
140 Fixed bug #678: CQL to PQF translation does not preserve double-quote
143 Fixed bug #689: SRU diagnostics to be added.
145 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
146 whether a connection is idle (no more work do do).
148 --- 2.1.34 2006/10/04
150 Change type of optval from long to int for invocation of setsockopt with
151 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
153 Added support for specifying the max log file size for the Generic
154 Frontend Server. The size is given with option -r.
156 --- 2.1.32 2006/09/21
158 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
160 --- 2.1.30 2006/09/17
162 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
165 Fixed bug in Generic Frontend Server that could cause a server to stop
166 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
168 For the generic frontend server, the maximum record size is used as maximum
169 size of incoming packages (SRU + Z39.50). The value until was previously
170 only used in Z39.50 Init negotiation and, later, in a session controlled
171 sizes of records returned. This is controlled using -k option. It can be
172 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
174 --- 2.1.28 2006/09/04
176 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
179 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
181 New option for yaz-marcdump -lpos=value which allows setting a portion
182 of MARC header to a certain value.
184 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
186 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
187 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
189 --- 2.1.26 2006/08/15
191 Fixed problem with SRU mode type (soap, get, post) for yaz-client
194 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
196 --- 2.1.24 2006/08/08
198 Fixed MARC ISO2709 encoding routines to deal with character set
201 Minor changes to GFS logging. Database included in search request log
204 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
205 cached/multiple records.
207 Shared libraries are built by default on Unix+configure.
209 Changed cql2pqf transformation to use a different evaluation order. The
210 new order is: always, relation, structure, position, truncation, index
211 and relationModifier. Old order was: always, relation, relationModifier,
212 structure, index, position, truncation. Note that the the latter ones
213 override former ones for identical attributes.. The new scheme means that
214 it is possible to override any existing attribute with a relationModifier.
215 And also that it is possible to override everything for the index rule
216 (except the ones listed in relationModifier). No order is perfect but this
217 one, we believe, covers more real cases.. The "always" should have been
218 called "default", since the attributes there can be overridden with all
221 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
222 compilation phase, but also for yaz-config --cflags output. This allows
223 us to have public headers with Libxml2 stuff in them . It should also,
224 eventually, make Libxml2 checks redundant in packages using YAZ, such
227 --- 2.1.22 2006/06/15
229 Changed SRU update structure bend_update_rr so that SRU diagnostics are
230 stored in uri, message and details.. Previously diagnostics were stored
231 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
232 compatibility.. but he's probably the only one affected, so.
234 Added support for CCL, compiled on the client side, in ZOOM-C. This
235 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
236 input; the resulting query objects can be used for for searching with
237 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
239 YAZ' configure searches for OpenSSL by default.
241 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
242 SL_CTX_use_certificate_file. See
243 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
244 for more info. Thanks to Ko van der Sloot.
246 --- 2.1.20 2006/06/02
248 Bug #600: SRU GET, POST support for yaz-client. Introduced
249 command 'sru' which selects method SOAP/GET/POST.
251 Allow missingValueAction to be specified for the sortspec string -
252 function yaz_sort_spec. By default, the missing value action is null.
253 Use ! to specify "abort". Use = followed by stringvalue to specify default
256 Ensured that Present-handler (if defined) is called in GFS before any call to
257 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
258 searchRetrieve requests.
260 Documentation for YAZ is now based on the Docbook XML/XSLT using
261 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
262 is no longer depending on jade/openjade or docbook-to-man scripts.
263 PDF is no longer part of the distribution - but can optionally be
264 made using DSSSL/jadetex or FOP.
266 Added retrieval handling support in Generic Frontend Server to support
267 conversion between MARC/XML as well as XSLTtransforms. See
268 etc/yazgfs.xml for an example.
270 Added Authentication support to Generic Frontend Server in SRU
271 mode. Authentication using HTTP Basic is supported, as is the use
272 of 'x-username' and 'x-password' parameters in the request itself.
274 Added support for a new character set MARC8s identical to MARC8 except
275 that it converts combined characters to single Unicode characters in the
276 Latin-1 range (when possible).
278 --- 2.1.18 2006/04/24
280 ASN.1 compiler 0.4: generates brief Doxygen file header for
281 generated .h/.c files.
283 Utility yaz_iconv now supports conversion to MARC-8.
285 New facilities for the MARC module. The reading - and writing of
286 content are separate methods for the yaz_marc_t handle. The following
287 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
288 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
289 format). Write functions have prefix yaz_marc_write_.. The existing
290 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
291 available. Removed support for OAI-MARC and simplexml (not the
292 simplexml from PHP5).
294 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
295 to be returned for this connection.
297 --- 2.1.16 2006/03/31
299 Allow multiple languages and charsets to be specified with
300 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
301 negcharset iso-8859-1,utf-8
303 Translation of proximity nodes from CQL into PQF now works.
305 Moved to automake 1.8, 1.9.
307 Added function yaz_log_set_handler which allows a log handler to be
308 installed. This handler will be called for all log messages. Output
309 to file is also produced; but that can be disabled by passing NULL
310 fname to yaz_log_init_file.
312 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
314 For SRW (including GFS), accept application/soap+xml as content-type
317 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
318 produces NO stylesheet reference even if a default stylesheet is specified
321 --- 2.1.14 2006/03/14
323 Updated Windows package to include yazd.dll + yazd.lib for the
324 Development component.
326 If the environment variable YAZ_LOG is set, then it is used as a
327 string indicating the default level of logging to use if not
328 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
329 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
330 used as before. So, for example, to omit warnings from YAZ logging,
333 cql_transform() now map structure and other attributes before indexes,
334 so that index-specific structures and other attributes can override
335 defaults. So now a combination of mapping specifications such as:
337 index.dc.date = 1=date-modified 4=5
338 does the right thing.
340 cql_transform() now also respects the "always" mapping specification,
341 which establishes an initial set of attributes to be used for all
342 terms except where overridden by more specific attributes associated
343 with the index, relation or modifier.
345 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
346 which mode to use; one of "post", "get" or "soap" (SRW, default).
348 Fixes for yaz_iconv routines: changed trie-based character set conversions
349 to use only non-negative values for bit fields due to Sun's C compiler not
350 supporting negative values.
352 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
353 sequences where not read correctly. Fix by Rustam Usmanov.
355 Updated win/makefile to use options, settings which makes things
356 compile with VS C 2005.
358 --- 2.1.12 2006/02/01
360 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
362 In ZOOM socket code, use select instead of poll on MacOSX.
364 ZOOM-C now support client-side compilation of CQL into RPN that is
365 sent to the server, enabling CQL to be used against all Z39.50
366 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
367 ZOOM_query object, and submit it using ZOOM_connection_search().
368 The CQL-to-RPN translation uses a configuration file, the name of
369 which must be specified in the Connection's "cqlfile" option.
371 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
372 function, which takes as its start-term parameter a ZOOM_query object
373 (which may have had either CQL or RPN set into it).
376 --- 2.1.10 2005/11/29
378 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
379 GFS to support this as well. Backend handler, bend_srw_update, does the
380 update work. Code contributed by Ko van der Sloot.
382 Allow retrieval of Search Result-1 information in ZOOM by the use of
383 options that are attached to a result set. ZOOM documentation updated
386 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
387 UTF-8 conversion. Patch by Raj Patel.
389 Added option -m to GFS to control formatting of timestamps in log file.
391 Added 'exit' as synonym for 'quit' in yaz-client
393 Added support for specifying SRW resultSetId + resultSetIdleTime in a
394 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
395 for the new members. Patch by Ko van der Sloot.
397 Added support for SRU POST. It is supported for content-type
398 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
400 Do not build the separate Multi-threaded (MT) library libyazthread.la.
401 Instead make the library libyaz.la multi-threaded. Threading as a whole
402 can still be disabled by configure option --disable-threads. Previosly,
403 with older GLIBCs there were problems with MT libs under Apache. This
404 has now been fixed a long time ago.
406 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
409 CQL module modified to be case insensitive for relations/indexes/operations.
411 Fixed bug in CQL transform code: incorrect value relationModifieder
414 Added 'show all' command for yaz-client which retrieves all results
417 Added new yaz-client, xmles, which takes a (private) OID and
418 a document to be sent as an extended service request.
420 Describe new yaz-client commands wait_response and set_auto_wait.
422 Increase TCP/IP listener backlog from 3 (which I am guessing was
423 copied from the SunOS manual entry way back when) so SOMAXCONN, so
424 that the socket will queue as many incoming connections as it's able
425 to handle ongoing connections. In other words, it will never now
426 refuse a connection that it would be able to handle merely because
427 it's not got around to accepting() enough of the pending connections
428 yet. This is the behaviour anyway under Linux, where the listen()
429 argument is ignored; but not under BSD and on systems such as
430 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
431 YAZ-based servers should now be uniform across operating systems in
434 yaz-marcdump uses 64-bit file access on some systems. This is enabled
435 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
436 This allows yaz-marcdump to read large MARC batches (>2 GB).
438 Modified all YAZ source files - except the source which is auto-generated
439 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
442 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
443 corresponding to the existing *_setl() function. These allow option
444 values containing arbitrary valuues.
446 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
447 ZOOM_resultset_sort() in new applications. Its behaviour is identical
448 except that it returns an indicator of whether or not the sort
449 criterion was accepted (0 for OK, -1 for invalid).
453 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
454 MARC output rather than returning "new" buffer.
456 yaz-client warns about unknown init options.
458 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
462 Added support for SRW sort in Generic Frontend Server. Patch
463 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
464 sortKeys - or NULL if none is provided.
466 Fixed bug #307: It was impossible to specify indefinite/no timeout
467 for ZOOM_event. Special timeout value -1 now means indefinite timeout
470 Added support for multiple languages and charsets to be specified in
471 ZOOM. Each charset/language is separated by a blank. If negotiation is
472 in effect in init-response, Option
473 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
474 Code based on patch by Vasiliy Osadchuk.
476 Fixed bug #306: infinite recursion that occurred when calling
477 yaz_log_level_init as the first call (before other log level or
480 Fixed bug in scan handling in front end server: if preferred-Position-In-
481 Response was non-present, a NULL pointer referece was performed.
485 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
486 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
487 now defined for all those error codes. So instead of putting 109 in
488 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
489 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
491 Modified the yaz-marcdump utility to skip garbage bytes between MARC
494 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
496 Program yaz-client now exits and produces an error message if multiple
497 Z39.50 servers are specified on the command line (none or one allowed
500 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
505 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
507 Fixed bug #272: Preserve spacing for CCL terms.
511 Added support for virtual hosts and multiple backend servers for
512 the YAZ frontend server. The configution is XML based and
513 support specificition of CQL to RPN mappings and explain information.
514 See section "Virtual Hosts" in the YAZ manual.
516 Extended OPAC display utility. OPAC display utility renders
517 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
518 to supplement yaz_marc_decode_wrbuf.
520 Fixed a bug in MARC decoder that could caused it to crash for some
521 invalid MARC records. More diagnostics and warnings where added in
522 XML output (warnings, etc are stored in comments).
524 --- 2.0.34 2005/02/08
526 Fixes for UNIX domain sockets. Bug #261.
528 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
530 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
531 Added yaz_marc_subfield_str which defines subfield lead string which is
532 used in YAZ_MARC_LINE format. Default string is blank+$. Added
533 yaz_marc_endline_str which defines end of fields string used in
534 YAZ_MARC_LINE format. Default string is newline.
536 Experimental support for MarcXChange. This format can be produced
537 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
538 http://www.bs.dk/standards/MarcXchange.xsd
540 Added yaz-client commands scansize that sets maximum number of
541 entries to be returned by scan.
543 --- 2.0.32 2005/01/11
545 Added support for SRW scan in yaz-client and Generic Frontend Server.
547 * Added whereInList member to SRW Scan Term.
549 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
551 Fixed NMEM system to return aligned blocks on the smallest boundaries
552 that are suitably aligned for all possible types on the particular
553 architecture YAZ is being built for.
555 --- 2.0.30 2005/01/04
557 Fixed numerious warnings that was issued with newer versions of GCC.
559 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
560 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
563 Make YAZ Generic Frontend Server slightly faster.
565 Enhance (and reduce) logging for Generic Frontend Server.
567 Revert YAZ log system so that it flushes every write operation
568 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
570 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
571 instead of LOG_, due to name clash with syslog(3). LOG_ are still
572 present. New applications should define YAZ_USE_NEW_LOG=1 - this
573 will effectively disable old definitions.
575 --- 2.0.28 2004/11/09
577 Added yaz_log_time_format which specifies log format using
580 Added yaz_log_module_level which returns mask for a module. Value
581 is non-zero mask a if module is enabled; zero if disabled.
583 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
584 in include/yaz/cql.h.
586 Fixed bug #176: Dont throw diagnostics on empty SRU args.
588 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
590 Fixed bug #172: RPM builds does not enable SSL.
592 Doxyfile.in part of dist. Doxyfile generated by configure.
594 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
595 are given and the corresponding component does not exist.
597 Extend CCL documentation in YAZ reference. Describe r=r.
599 --- 2.0.26 2004/10/01
601 Fixed MARC->MARCXML conversion to properly deal with
602 fields, subfields, indicators having non-ASCII characters.
604 Fixed MARC->MARCXML conversion so that ASCII control characters
605 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
608 Added YAZ GFS support for conversion from Z39.50 surrogate
609 diagnostics to SRW surrogate diagnostics.
611 Bug fix: YAZ GFS did not return schema in explainResponse.
613 --- 2.0.25 2004/09/30
615 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
616 now converts recordSchema to elementSetName as well as schema URI.
618 Fixed bug in COMSTACK that prevented HTTP request packages from being
621 --- 2.0.24 2004/09/29
623 Added CCL facility r=r "range" which is similar to r=o "ordered" but
624 does not require white-space before and after the dash in a range, e.g.
625 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
628 Fixed a few AC_TRY_LINK configure tests that did not operate properly
629 due to new GCC removing "redundant" code.
631 Added yaz-client commands scanpos and scanstep that sets preferred
632 position and step-size for scan.
634 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
636 Added CCL utility ccl_qual_buf which parses one or more CCL
637 spec lines in a buffer.
639 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
640 of name and value - ignoring empty lines and comments.
642 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
644 Added odr_get_element_path which returns current element path for an
645 ODR handle. This utility is useful in error handling or user-defined
648 Added ODR_PRINT utility odr_set_stream which is is a more generic
649 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
650 to a write function and pointer to close function. The close function - if
651 non-NULL - will be called during odr_destroy.
653 Fixed bug in CCL parser where truncation char was not removed from
654 right side when truncation=both was in effect.
656 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
659 --- 2.0.23 2004/08/11
661 Fix buffer overrun in CQL parser when dealing with proximity (%).
663 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
664 to UTF-8/UCS conversion is now only based on codetables.xml.
666 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
668 --- 2.0.22 2004/08/06
670 Add support for more "commit changes" in ZOOM (uses Extended Services).
672 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
675 Yet another small fix for configure of SSL.
677 --- 2.0.21 2004/05/14
679 Fix SSL libs for configure when --with-openssl=DIR is given.
681 --- 2.0.20 2004/05/10
683 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
685 SSL comstack now uses yaz.pem certificate file on server side
686 by default. Certificate filename can be configured by calling
687 comstack function cs_set_ssl_certificate_file before cs_bind is used.
689 Fix bug regarding multiple calls to ZOOM_connection_connect.
691 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
693 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
694 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
696 ZOOM now allows inspection of X509 peer certificate for verification.
697 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
699 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
700 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
701 as "modular" but it simplifies things.
703 Added cs_get_peer_certificate to that returns peer X509 PEM.
705 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
706 NULL if SSL is unavailable.
708 Documentation about MARC decoding tools.
710 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
712 --- 2.0.19 2004/03/30
714 Rename CHANGELOG to NEWS to follow GNU style packing.
716 Fix bug with missing initialization of member in init_diagnostics.
717 This bug affects threaded version of GFS server.
719 --- 2.0.18 2004/03/20
721 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
724 Ensure zlib.dll is packed with Windows install.
726 --- 2.0.17 2004/03/17
728 Fix encoding of xsd:string to use text instead of CDATA.
730 Fix endless loop in CQL parser with unbalanced ".
732 Use a more compact way to store MARC-8 conversion tables.
734 --- 2.0.16 2004/03/16 Debian only
736 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
739 Update CQL parser to use new CQL 1.1 modifiers for booleans and
744 --- 2.0.15 2004/03/01
746 Another fix for decoding of XML packed records.
748 --- 2.0.14 2004/02/25
750 Fixes for Chunked encoding. White space not ignored after length spec.
752 Update NS and use default NS for SRW diagnostic elements.
754 --- 2.0.13 2004/02/23
756 Implement ZOOM_resultset_cache_reset which resets record cache.
758 Implement ZOOM_resultset_sort which sorts a result set.
760 Implement chunked HTTP transfer.
762 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
764 --- 2.0.12 2004/02/16
766 Added member 'schema' to bend_explain_rr structure so that backend
767 can specify explain record identifier. Defaults to Zeerex 2.0.
769 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
771 --- 2.0.11 2004/02/16
773 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
776 Added init command for yaz-client which sends "extra" init request.
778 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
779 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
781 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
783 Make ZOOM error code for "invalid query".
785 Fixed compilation for SSL which wasn't properly enabled for all platforms.
787 --- 2.0.10 2004/02/05
789 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
792 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
794 Added option -p <file> to make Generic Frontend Server to write PID file.
796 Added option -D to put Generic Frontend Server in background on its own.
798 Make ZOOM C recognize option "password". If unset, "pass" is used
799 (for backwards compatibility).
801 Fixed a bug in Generic Frontend Server that could make it crash if a
802 client sets characterSetNegotation bit, but didn't pass negotiation stuff
805 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
806 Must be issued before open, in order to be in effect.
808 --- 2.0.9-6 2004/01/12 Debian/Windows
810 Make the SRU server more picky WRT unknown params, etc.
812 Bug fix: ZOOM scan response didn't return displayTerm - when present.
814 New YAZ client command, options, that sets Z39.50 options.
816 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
817 options from a string of tokens (one token for each option bit).
819 Update SRW diagnostic code messages.
821 --- 2.0.9-5 2004/01/07 Debian/Windows
823 Handle user defined stylesheet for SRW/SRU.
825 --- 2.0.9-4 2004/01/06 Debian/Windows
827 Fix bug in decoding of Content-Length.
829 --- 2.0.9-3 2004/01/06 Debian/Windows
831 Fix a bug with decoding of XML packed records.
833 --- 2.0.9-2 2004/01/05 Debian only
835 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
837 Fix bug in SRW/SRU diagnostics decoding.
841 Fixed bug in Generic Frontend Server which could drop records exceeding
842 preferred message size. Reported and fixed by Irina Dijour.
844 Fixed calculation of package size for structured records in Generic
845 Frontend Server. Reported and fixed by Irina Dijour.
847 Fixed namespace for SRW/SRU diagnostics.
849 Fixed SEGV in yaz-client that occured for HTTP connection errors.
853 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
854 this version is incompatible with version 1.0 and older YAZ SRW/SRU
857 CQL changes to reflect recent changes to the specification:
858 * Documentation talks about context sets instead of index sets.
859 * Documentation talks about indexes instead of qualifiers.
860 * The CQL-to-PQF transformer's configuration file now uses
861 "index.set.name = <attributes>" instead of the old form
862 "qualifier.set.name = <attributes>". (Both forms are still
863 understood but the latter is deprecated.)
864 * CQL terms with no explicit index specified are now interpreted as
865 cql.serverChoice instead of srw.serverChoice (which of course
866 behaves exactly the same.)
870 MARC conversion can now generate ISO2709 output in another
871 character set. yaz-marcdump uses this facility if you invoke it
874 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
875 functions from there can be used from C++.
879 Frontend server now transfers memory from decoded packages to stream
882 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
883 references to show up.
885 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
886 the ZOOM Abstract API. The older names for the same options are still
887 also supported for the benefit of old applications.
889 ZOOM-C supports "implementationId" and "implementationVersion" options
890 to go along with "implementationName". These allow the user code to
891 specify identification strings to be sent to servers.
892 Add OID for the new ExtLite attribute set.
894 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
895 as requested/supplid by Ere Maijala <ere@atp.fi>
897 For generic frontend server, reverse the order of
898 "toolkit-supplied / application-supplied" strings sent as implementationId,
899 Name and Version. Also, remove the spaces around the slash. This brings
900 the GFS in line with the behaviour of ZOOM-C on the client side.
902 Add function ZOOM_scanset_display_term.
904 yaz-client shows scan displayTerm if present.
906 Utility yaz-iconv is now installed by default along with the man page
909 Extend configure check for OpenSSL to use pkg-config where available (such
912 Incorporate patch by Morten Bogeskov which allows a Unix file socket
913 server to specify uid/gid/mask for socket using the format
914 unix:[user=uid,][group=gid,][umask=mask,]file=path
915 If file= is omitted the existing format is assumed, e.g.
917 in which case the mask is 0666 (rw for everybody).
919 Major restructure of YAZ source. All source in libyaz is in src directory.
920 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
921 util (utility programs such as ASN.1 compiler, yaz-marcdump).
923 Added man page for utility yaz-marcdump (used to be called marcdump).
924 yaz-marcdump is installed by 'make install'.
926 Fixed a memory leak in Generic Frontend Server that occurred when decoding
927 of incoming package failed.
929 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
931 Change prototype of odr_perror: add const to message string.
933 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
935 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
936 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
937 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
938 DNS lookup. There should not be any compatibility problems with this
939 assuming that blocking=1 or 0 is used.
941 Fix bad reference in UNIX comstack in function cs_addrstr.
943 Fix for compilation on AIX.
945 The generic front-end server (server/seshigh.c) now supports returning
946 Init diagnostics to the client in User-information-field, in
947 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
952 Allow any CQL relation (not just all,any,exact,scr).
954 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
955 that features the same UI.
957 Implemented command update0 in YAZ client which is equivalent to
958 update but uses old of Ext Update ASN.1.
960 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
961 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
962 Previously no OID was used for this info.
964 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
965 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
966 returns 'malformed search term' otherwise.
968 SortResponse member resultCount now set to NULL in sort handler of
971 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
974 Add three new utility functions for translating OIDs between various
975 formats -- symbolic name such as "Usmarc", minus-1-terminated int
976 arrays and dotted strings such as "1.2.840.10003.9.5.1":
977 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
978 char *oid_to_dotstring(const int *oid, char *oidbuf);
979 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
981 Reverted modifications for ES Update definition for z_IU0Update
982 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
983 is back to YAZ 2.0.2.
985 String value attributes for CCL parser.
987 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
988 which their FirstSearch server returns in Init responses, sometimes
989 carrying useful diagnostic information when Init fails. This has the
990 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
991 "z39.50/oclcui.asn", where its definition is somewhat different from
992 what OCLC document on their web-site, as required to interoperate with
995 Support for anonymous authentication in yaz-client. Use the command
998 * Fix the OID of the Index Data-local "admin" Extended Service from
999 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1000 the 1000, which indicates a locally-defined OID, was a mistake.
1002 --- 2.0.3 2003/06/20
1004 Fix CCL directive @case handling so that it affects string match for
1005 both CCL keywords and qualifiers.
1007 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1008 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1009 Decoder has been updated with ASN.1 changes as listed in
1010 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1011 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1012 z_IUUpdate, remains unchanged.
1014 ZOOM_record_get may now return a record in a specific character set.
1015 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1016 "from" is the character set of record as returned by target. "to" is
1017 the character set to be returned. If omitted, "to" is UTF-8.
1019 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1021 New ODR utility, odr_getelement, which returns name of element for
1022 which encoding/decoding failed.
1024 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1025 in cases where a required element was omitted.
1027 Bug fix: some MARC8 sequences were not converted.
1029 New ZOOM option "step" which specifies number of records to be
1030 retrieved in one chunk. Used in conjunction with "start" and "count".
1032 SRW support for yaz-client. Use scheme http: to use it, e.g.
1035 yaz-client no longer does (un)intelligent character set conversions
1036 by default. Can be enabled with charset and marc_charset commands.
1038 xmalloc trace fix for 64-bit systems such as DEC alpha.
1040 Solaris 2.6 compile fix.
1042 New function, cql_strerror() translates SRW error codes, as returned
1043 by cql_transform_error(), into human-readable English strings. Used
1044 in yaz-client diagnostics when appropriate.
1046 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1047 converts it into a type-1 query which is sent to the server. This
1048 makes CQL available for use with all Z-servers, as opposed to the tiny
1049 minority that can handle CQL queries themselves.
1051 --- 2.0.2 2003/04/28
1053 New Debian package layout similar to the Redhat Package layout.
1055 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1056 and search result respectively.
1058 --- 2.0.1 2003/04/25
1060 Redhat package is now several packages: libyaz (runtime libraries),
1061 libyaz-devel (development and documentation, and yaz (utility programs).
1062 Package spec file by Morten Bøgeskov.
1064 New member 'schema' in struct bend_fetch_rr which the name of requested
1065 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1066 handler MAY set this to reflect the schema of the returned record.
1068 New member 'display_term' in struct scan_entry. GFS now sets member entries
1069 and allocates scan entries to be filled by user scan handler. In previous
1070 version, entries member was allocated by the scan handler. That still works,
1071 but the GFS will ignore member display_term - assuming it was NOT set by
1072 the handler. The fact that the GFS now allocates the entries both allows
1073 for new members and makes a scan handler easier to write.
1075 Fix CQL lex buffer overflow.
1077 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1078 SRU default recordPacking is string.
1080 SRU protocol support for frontend server.
1082 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1084 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1086 Added scan for the ZOOM shell (zoomsh).
1090 * String Identifers for Schemas (Amendment 5).
1091 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1092 Old definition for schema
1093 Odr_oid *schema; /* OPT */
1098 Z_InternationalString *uri;
1099 #define Z_Schema_oid 1
1100 #define Z_Schema_uri 2
1103 * resultCount parameter to Sort Response (Amendment 1).
1104 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1106 Support for SRW 1.0 over HTTP. This is an optional feature and
1107 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1110 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1111 on the same port. SRW SearchRetrieveRequests are mapped
1112 to bend_init,bend_search,bend_fetch,bend_close.
1114 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1116 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1117 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1119 ZOOM connections are SRW based if schem http is used for hostname
1120 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1121 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1123 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1124 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1125 distance=n, order=true/false, relation=le, prox unit=word. If
1126 n is omitted, distance 1 is used.
1128 Fixed problem with C compiler include path in wrong order.
1130 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1131 on Solaris. Patch from Ko van der Sloot.
1133 New MARC decode API. All new functions operate on a yaz_marc_t
1134 handle. The most important new functions are: yaz_marc_create,
1135 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1136 decode and destroy respectively. Decoder can produce formats
1137 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1138 include/yaz/marcdisp.h.
1140 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1141 to UTF-8, UCS-32, wchar_t or Latin-1.
1143 * Prototypes for yaz_iconv_-functions moved to separate header
1144 include/yaz/yaz-iconv.h.
1146 Make a few private functions 'static' in unix.c. This prevents
1147 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1149 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1150 are set when Init Response is received.
1152 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1153 but returns diagnostic set as well.
1155 New function yaz_strerror which is a portable wrapper for
1156 strerror/strerror_r/GetLastMessage.
1158 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1159 is returned for MARC. If type is "oai", then OAI MARC is returned.
1161 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1164 --- 1.9.2 2002/11/26
1166 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1168 Fix bad race conditions on SIGTERM and terminate gracefully in
1171 Move retrieval (data1) module to Zebra since nobody seems to be
1174 Add GRS-1 render for ZOOM using same format as yaz-client.
1176 --- 1.9.1 2002/10/05
1178 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1180 Fix broken ESpec handling in data1 module.
1182 SGML reader parses comments and makes them part of the data1 tree.
1184 Added several type casts so that YAZ compiles as C++ code.
1186 ZOOM didn't handle PDU encoding failures properly.
1188 Added more Bib-1 diagnostics (approved extensions).
1190 GNU configure: better check for iconv.
1192 More portable use of accept, getpeername. Check for socklen_t. Use
1193 int/size_t if socklen_t is not defined.
1197 PQF parser rejects bad queries - including those with extra
1198 characters in them. PQF parser used to silently ignore that.
1199 Cleaner API for PQF added, which allows you to get detailed
1200 error information for bad queries (see yaz/pquery.h).
1202 Fixed bug in ZOOM_record_get for type "database".
1204 Implemented mini iconv library supporting conversions between
1205 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1207 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1209 --- 1.8.9 2002/08/20
1211 Fixed ZOOM C record cache so that preferredRecordSyntax and
1212 elementSetName is used to check for already fetched records.
1214 --- 1.8.8 2002/08/02
1216 Added three members in bend_initrequest structure to facilitate
1217 character set negotiation.
1219 Fixed a bug in frontend server that could cause indefinite
1220 loops under rare conditions.
1222 Revised character set utilities (charneg.h) so that encoding
1223 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1225 For PQF, directive @term <type> sets term type for Scan/Search.
1226 Here <type> is general, string, numeric, null. The term type
1227 is inherited - just like @attr.
1229 New call odr_set_charset that sets character set conversion for
1230 international-strings on a ODR stream. Prototype is:
1231 int odr_set_charset(ODR o, const char *to, const char *from);
1232 The InternationalString is still represented as C string in YAZ
1233 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1234 won't). On the protocol level, you can use any encoding.
1236 Support for UNIX sockets in ZOOM.
1238 Solaris recv sometimes returns errno == ENOENT. It is treated as
1239 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1241 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1242 both client and server. Code by Morten Bøgeskov.
1244 --- 1.8.7 2002/05/22
1246 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1247 that they can be used directly from Visual Basic. You must recompile
1248 your windows APP if you're using ZOOM.
1250 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1251 Commands "lang" and "charset" sets language and character set respectively.
1252 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1253 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1255 Attributes from multiple CCL fields may be OR'ed rather than merged
1256 using directive "@field or". Fields are still merged by default -
1257 equivalent to "@field merge".
1259 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1262 Fixed bug in zget for parameter ExtendedServicesResponse.
1266 --- 1.8.6 2002/03/25
1268 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1270 Client displays USR.1:SearchResult-1 (hits per term).
1272 Additional Search Info for search in Generic Frontend Server.
1274 Fixed CCL parsing of "field=s".
1276 WIN32 installer - using the excellent NSIS software from nullsoft.
1278 Fixed CCL parsing of "field = - <number>".
1280 Added function yaz_marc_decode that decodes MARC for line mode
1281 display or XML (similar to that used by JZKit).
1283 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1284 Z39.50. But ISO/ILL was, however.
1286 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1287 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1292 --- 1.8.5 2002/02/03
1294 New YAZ client features: Command completion and new commands:
1295 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1296 Code provided by Jacob Poulsen.
1298 New call oid_trav, that visits all registered OIDs via callback.
1300 Function ZOOM_record_get now returns const char pointer rather than
1301 void pointer. It saves a lot of type casts.
1303 For YAZ client, command "auth" now allows you to set authentication
1304 in IdPass style. It is enabled when three tokens are given - order
1305 is user, group and password.
1307 Fix memory leaks in MARC record handling for ZOOM.
1309 New option for YAZ client, -k <kilobytes> that sets
1310 maximum record size. Similar to -k option for generic frontend
1311 server and yaz-ztest.
1313 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1315 Prefix query parser reports "fail" when bad attribute set is given.
1317 Fix in MARC decoder. Proximity logging. Fix for attribute set
1318 in scan handler for server. Patches by Shigeru Ishida.
1320 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1323 Configure option --with-openssl=<dir> now works when a directory is
1324 specified. Patch provided by Morten Bøgeskov.
1326 New option for YAZ client, -u <auth>, that sets authentication.
1328 ZOOM fix: error information was sometimes "missing", since error
1329 was cleared/reset too when it shouldn't.
1331 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1333 --- 1.8.4 2002/01/04
1335 Scan for ZOOM API. New object ZOOM_scanset. New functions
1336 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1337 ZOOM_scanset_destroy.
1339 New ZOOM function, ZOOM_connection_last_event, that returns type
1340 of last event (such as "receive data", "send data", "apdu received",
1343 New ZOOM option, schema, that specifies schema for retrieval.
1345 New CCL feature. Qualifiers can be aliases for one or more
1346 other qualifiers (if more than one is given, OR is used).
1348 ZOOM uses named result sets if target supports it.
1350 Two new YAZ client commands: . (dot, which sources a script of YAZ
1351 client commands), and ! (to execute shell command.). Implemented
1354 Working on Debian packages.
1356 --- 1.8.3 2001/11/19
1358 YAZ client enables named result sets only if target supports it.
1360 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1362 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1363 with key="host" to get same result.
1365 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1366 Function Z3950_resultset_record(s) returns references to records
1367 "owned" by resultset. To become owner use Z3950_record_clone.
1369 Function z_ext_record handles Extended Services. Thanks to
1372 --- 1.8.2 2001/11/12
1374 CCL Parser fix: ignore token comma when dealing with and-lists.
1376 Documentation updates for COMSTACK.
1378 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1379 Changed prototype Z3950_records. For some functions, int parameters
1380 were changed to size_t.
1382 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1385 New MARC decode/display function, marc_display_exl, which properly rejects
1386 non-ISO2709 records. YAZ client uses it.
1388 --- 1.8.1 2001/10/29
1390 Fix bug: local attribute set wasn't set correctly in PQF strings.
1394 * Old Z39.50 codecs no longer supported.
1396 Added ZOOM C binding. See http://zoom.z3950.org/
1398 Renamed states for COMSTACKs to avoid confusion with events.
1400 Implemented cs_look and proper cs_rcvconnect.
1402 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1404 Configure detects POSIX threads on OpenBSD.
1406 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1407 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1409 When error is returned from present handler, non-surrogate diagnostic
1410 is returned in present response (and fetch handler is no longer called).
1412 * Minor adjustments to pquery parser (PQF). Token characters may be
1413 escaped by using backslash (C-style).
1415 PQF parser allows string attribute values to be specified. For @attr,
1416 non-numeric characters after the equal-sign are treated as strings
1417 (e.g. @attr 9=title).
1419 CCL trunction character may be defined (@truncation in file)
1421 * function zget_ExtendedServicesRequest sets waitAction to
1422 waitIfPossible (was wait).
1424 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1427 CCL operator names may be set in field definition files (CCL_bibset).
1428 See ccl/bib1 for an example.
1430 Fixes in ASN.1 compiler for C++ compatibility.
1432 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1433 and "op_or" to avoid conflict with C++.
1435 Fixed problem with GNU readline detection on Redhat 7.0.
1437 Added step-size for Scan backend handler.
1439 Fixed bug that made the frontend server crash when no attribute
1440 set was specified for scan.
1442 Front-end server automatically switches to original working directory
1443 when installed as an NT service. Previously -w had to be specified to
1446 Added extended attributes for retrieval module (data1), so that data1
1447 records carry d1_readXML/SGML attributes. d1_read also supports
1448 null-data rules ( <tag/>)
1450 On UNIX when POSIX threads are available, a separate library libyazthread
1451 is created. Programmers should link with that library and the yaz library
1452 when using threads. The reason for the split was that some applications
1453 on Linux, such as Apache, doesn't work well when using shared objects that
1456 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1457 (or any frontend server) in SSL mode by specifying ssl: followed by
1458 address. Only tested on UNIX.
1460 Added feature for CCL module. Virtual structure s=al or s=ol generates
1461 and-list and or-list respectively instead of phrase search.
1465 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1466 log_mask_str. This was done to avoid name conflicts with other libraries
1467 (such as other PHP extensions).
1469 Added raw OID member for preferred record syntax (request_format_raw)
1470 and returned record syntax (output_format_raw) for backend fetch method.
1472 Config file yaz-config now accepts options so that it returns specific
1473 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1475 Shared library support for UNIX using GNU libtool.
1477 * Modified backend interface. Request/Response struct's replaced by
1478 one read/write C struct. For example bend_fetchrequest and
1479 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1480 Every handler - even search has to be registered in bend_init
1481 handler. This means that the YAZ library no longer refers to
1482 external functions and it makes it possible to make the whole
1483 thing a single DLL/SO.
1485 Added Segment handler for backend server.
1487 Added Zmbol/Zebra administrative functions to YAZ client.
1489 Threaded frontend server on UNIX (when POSIX Threads are available).
1490 Starting the server with option -T enables multi-threading.
1494 Added configure option --enable-comp/disable-comp to control use
1495 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1496 located in sub directory asn.
1498 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1499 in ${exec_prefix}/bin along with the other programs yaz-client and
1502 GNU automake used to maintain makefiles.
1504 Added several OID's.
1506 Changed retrieval module so that we can load records with no abstract
1507 syntax defined. Tagpaths in these records are fully composed of string
1510 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1514 On UNIX, the generated makefile now supports a proper 'make install'.
1515 The prefix can be set via GNU configure to set the install location
1516 (default is /usr/local).
1518 * YAZ programs client and ztest were renamed to yaz-client and
1519 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1520 locations, such as /usr/bin,/usr/local/bin,etc.
1522 * YAZ Header files were moved from include to include/yaz. YAZ Header
1523 files are referred to as include <yaz/log.h> rather than <log.h>.
1524 The YAZ include path (-I ..) is therefore the same as before. Programmers
1525 should update their #include statements or use -Ipath/include/yaz
1526 instead. The main motivation for doing this change is that YAZ header files
1527 can be installed in "standard" locations /usr/include,/usr/local/include
1528 without introducing conflicts, since ALL YAZ header files are stored
1529 in subdirectory yaz (under /usr/include for example).
1531 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1532 rather than project/workspace files. We switched because project files
1533 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1536 Changed name of logging function, logf, to yaz_log, to prevent name
1537 clash with some math-log functions. The YAZ header log.h defines logf
1538 to yaz_log (#define) so there should be no incompatibilities by this
1541 Added bend_start/bend_stop handlers for server. These handler are
1542 called on start/stop of server. For windows they are called whenever
1543 a service is started/stopped.
1545 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1546 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1547 in util/yc.tcl. The auto-generated C code structures are, in a few
1548 cases, incompatible with the old decoders. There are differences in the
1549 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1550 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1551 The preprocessor variable ASN_COMPILED is defined when the compiled
1552 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1553 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1554 wish to use the old encoders/decoders you can specify --disable-yc
1557 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1558 version so that it supports both new - and old version of DB Update
1560 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1561 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1562 change. The name parameter can be set to 0 in which no name is specified
1563 for the construction. The macros odr_implicit and odr_explicit sets name
1564 parameter to zero for the construction involved. New macros
1565 odr_implicit_tag and odr_explicit_tag are similar to the others,
1566 except that a name parameter is added. For programmers' that don't use
1567 ODR they probably only need to change the call to z_APDU and z_External.
1569 Added access control facility by interfacing the TCP wrapper library.
1570 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1571 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1572 name of the daemon and enables the access control as specified in
1573 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1575 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1576 den Dool <H.M.vdnDool@kub.nl>.
1578 Added reference ID parameter to most functions in server API - refer
1579 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1581 Changed name of ccl library to libccl.a (was ccl.a).
1583 Fixed bug in decoder for Explain (Category TargetInfo).
1585 Added support for GNU readline in client. Thanks to Jacob Poulsen
1586 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1588 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1589 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1590 IMPLEMENTATION! This change was made to the development version before
1591 the ZIG decided to retract the amendment. If any users MUST be
1592 compatible with the original Update definition, PLEASE CONTACT US, and
1593 we will include a separate definition corresponding to the old Update
1594 ES. Note that because of the change to the ASN.1 of the
1595 TaskPackageRecordStructure we cannot define a single structure that
1596 will support both versions.
1598 * Added const modifier to buffer parameter for some ODR/BER encoding
1599 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1600 completeWAIS, odr_dumpBER.
1602 Fixed bug in client.c which caused a crash when a scanResponse didn't
1603 contain positionOfTerm.
1605 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1606 * will cause an error in a client if a non-YAZ target sends both a
1607 * list of Scan entries and non-surrogate diagnostics.
1609 Retrieval module enhancements. Tag sets may be typed in the reference
1610 to it. From the .abs-file the "tagset" directive takes a third optional
1611 integer type for the tag set referenced. From a .tag-file the "include"
1612 directive takes a third optional type as well. The old "type" directive
1613 in the tag set itself is still recognized but acts as the default type
1616 Backend interface change. Individual Scan terms returned from bend_scan
1617 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1618 in include/backend.h.
1620 Retrieval module enhancements. Multiple tag sets and attribute sets may
1621 be specified in abstract syntax specs. Revised the error/warning for
1622 logging messages reported by the retrieval module when reading the
1625 Object Identifier system (oid_..) changed. The API is backwards
1626 compatible but the oid-routines now allocates new OID's when needed.
1627 Raw OID's may be specified in oid_getvalbyname.
1629 YAZ now uses GNU configure to generate Makefile(s).
1631 * Minor changes in some of the member names of DeleteResultSetRequest and
1632 DeleteResultSetResponse. See include/proto.h.
1634 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1635 and added member 'languages' in TargetInfo (which was missing).
1637 Changed the way attribute sets are handled in the retrieval
1638 module. These are now cached, just like the abstract syntaxes
1641 Changed YAZ so that it links with compiled ASN.1.
1643 Added Explain-schema definitions and mapping routines. The following
1644 Explain categories have been implemented: AttributeDetails,
1645 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1647 Fixed minor bug in Windows version of Server Library.
1649 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1651 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1653 Added EXTERNAL: UNIverse Resource Report (non-standard).
1655 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1656 ENUMERATED and SET OF.
1658 * Added 'const' to some of the char pointer arguments for the
1659 functions, data1_read_node, data1_getelementbytagname,
1660 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1663 Fixed bug in data1_insert_taggeddata - the last_child member of
1664 parent wasn't initialised.
1666 * Changed data1_read_record and data1_read_node so that the supplied
1667 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1668 doesn't refer to any parts of the "SGML"-buffer.
1670 Fixed bug in server library (Windows version of statserv_remove).
1672 * Changed code so that it compiles as C++. The type definition
1673 of Odr_fun which is a member of Odr_arm was changed. The result is,
1674 that an explicit typecast is needed for the fun pointer when
1675 using Odr_arm - as in:
1676 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1678 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1680 Implemented the new structured date and time definition as approved
1681 by the ZIG. Added schemaId element to the specificTag in Espec-1
1682 (also approved at the last ZIG). Thanks to RVDM.
1684 Added some Object identifiers (RVDM).
1686 Changed the Update Extended Service (RVDM).
1688 Added command "refid" to client which specifies referenceId for
1689 the following requests.
1691 Implemented extended service handling for server. See ztest.c
1692 for an example as well as backend.h. New handlers are registerd
1693 in the Init handler.
1695 * Changed interface for sort in server.
1697 Added new members to statserv_options_block. It allows a server
1698 to read options from another source than just the command line. Thanks
1699 to Charles Woodfield.
1701 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1702 renamed to zboolean. Some C++ compilers complained about the name.
1704 Minor changes to gils.abs. Added index 's' (sort) on title
1705 and date/time-last-modified.
1707 --- 1.4pl2 1998/1/30
1709 Fixed bug in server library regarding inetd mode (-i). This bug
1710 was introduced by release 1.4.
1712 --- 1.4pl1 1998/1/29
1714 Added sort facility in client and backend server interface.
1716 Fixed problem with dependencies in Makefile(s).
1718 Fixed bugs for encoders/decoders of extended services and
1721 Implemented sub-tree feature for schemas. Sub-trees are
1722 referenced in *.abs-files. See explain.abs for an example
1723 of the use of this feature.
1725 Modified bib1.att; local attributes for ANY didn't include
1726 ANY itself (only affects use of the retrieval module).
1728 Fixed bug in plain SGML reader in function data1_read_node:
1729 tags with prefix "var" was incorrectly interpreted as variants.
1731 Added feature "sub-schemas" to enable references to - and definitions
1732 of - group of elements.
1734 * Removed member parent from type data1_element (in data1.h).
1736 Implemented function odr_nullval() that returns the value of
1739 * Removed member num_children from data1_node (in data1.h).
1741 Made NT service interface part of the server library. The
1742 function statserv_main uses the NT service when required and
1743 calls the statserv_start / statserv_close routines.
1745 Routine zget_SearchRequest and zget_PresentRequest fills
1746 resultSetName/Id member with "default" instead of "Default".
1748 Fixed memory leak in server. Request queue member wasn't freed.
1750 Fixed nmem_exit so that memory is freed.
1754 Revised the CCL parser utility to be thread safe.
1756 Added function, oid_ent_to_oid, to replace the function
1757 oid_getoidbyent, which is not thread safe.
1759 * Added nmem_init and nmem_exit to initialize and release
1760 NMEM resources. Function nmem_init should be called once in the
1761 initial thread before NMEM/ODR is used. statserv.c and client.c
1762 have been changed accordingly. The change was necessary to make
1763 NMEM thread safe. The NMEM memory pool is shared amongst threads
1764 in a process. Unix-based applications will still work fine without
1767 Added NT Services interface for the the Z39.50 (statserv) Server.
1768 Refer to the ztest.c source on the usage.
1770 Windows 95/NT port using MSVC5.0. Project files are included in the
1773 * Defined new 'global' handle for the retrieval (data1) system. The
1774 new handled, data1_handle, describes the state of the data1 system.
1775 This handle is passed as first argument to virtually all
1776 data1 related routines. The functions data1_create and data1_destroy
1777 creates and destroys a data1 handle respectively.
1779 Added ODR encode stream member to all backend request structures
1780 init, search, scan etc. This stream should be used to allocate all
1781 memory used for the response when thread safe operation is needed.
1783 Changed the comstack utility, cs_addstr, to be thread safe. The
1784 returned hostname string returned by the function is now part the
1787 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1788 function. The cs_straddr takes a COMSTACK handle as argument, so this
1789 function must be used after cs_create and before bind/connect.
1790 This function is thread safe.
1792 Moved test server to 'ztest' directory - generic server code still
1793 in 'server' directory.
1795 Made prefix query (pquery.c) utility thread safe.
1797 Added new function modifier YAZ_EXPORT to 'export' public DLL
1798 functions when using windows (see include/yconfig.h).
1800 Added definitions to the OID database (util/oid.c) (RVDM).
1802 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1804 Added call to ccl_rpn_delete in client program.
1806 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1807 release of RPN structure.
1809 Added support for C++, headers uses extern "C" for public definitions.
1810 With input from RVDM.
1812 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1813 Thanks to Ronald van der Meer (RVDM).
1815 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1817 Added support for private extensions to the OID database
1818 (oid_setprivateoids()). Thanks to RVDM.
1820 Added optional, physical ANY (key replication)
1822 Fixed null-reference problem in GRS-1 output filter.
1824 Proximity operator added to Prefix Query Format (PQF).
1826 In test client command "base" accepts multiple databases.
1828 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1832 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1834 Smallish bug-fixes in the new encoders/decoders (explain).
1836 Bug fixed in DeleteRequest.
1838 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1840 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1842 Added SOIF syntax (using private OID for now) to retrieval module and client.
1844 Added Update extended service.
1846 Added SearchResult-1 additional info structure.
1848 Added optional CCL (ISO8777) interpreter as separate module. Available
1851 --- 1.2 1996/6/10 (1st anniversary release)
1853 Added Summary record syntax. Lightly tested.
1855 Added OPAC record syntax. Untested.
1857 Added ResourceReport service encoders/decoders. Untested.
1859 Fixed bug in z_Unit - wrong tagging on unitSystem.
1861 Fixed bug in the DiagRecs decoder.
1863 Added options for max PDU size and session timeout to frontend-server.
1865 Added documentation of query-language parsers and other supporting utilities.
1867 [frontend-server] Added Attribute set to the bend_scanrequest API.
1869 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1870 surrogate diagnostics were generated.
1872 [retrieval] Allow multiple local values for attribute.
1874 [retrieval] Allow multiple attributes per element in .abs files. index type.
1876 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1878 --- 1.1pl2 1996/4/10
1880 Minor changes, mostly specific to Zebra's requirements (retrieval)
1884 Repaired bug in frontend server when running multiple listening
1885 endpoints in dynamic mode.
1887 z_External() now won't break if a known, ASN.1 value comes encapsulated
1888 in an octet-string. The value will pass through unmodified in an Odr_oct.
1890 Added a bit of code to the demo client to decode & display
1891 ASN.1-structured records represented in the octet-aligned branch of
1892 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1894 Added z_ext_getentbyref() to the ASN module. Doc updated.
1896 * Completed the SCAN definition in the ASN module. This may break SCAN
1897 code based on older YAZ-versions at compile-time. The fix is easy -
1900 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1901 under the SCAN definition. Remember to initialize this, server-people.
1903 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1904 that this does not extend to ODR and ASN.
1906 Comstack allows insertion of established socket (primarily for
1907 inetd-operation of servers). Doc updated.
1909 Front-end server can now start from the inetd in TCP mode. Doc
1912 --- 1.0pl4 1996/1/24
1916 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1917 the rank and record number.
1919 Adjustments to the frontend server.
1921 Fixed diagnostic BER dumper. It ignored the file argument.
1925 Various changes to retrieval module.
1927 Changed the union discriminators of the protocol files from enums to
1928 ints paired with #defines.
1930 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1933 *Changed operator in the RPN structure to 'roperator', again to avoid a
1936 Fixed problems in Explain decoders/encoders.
1938 --- 1.0pl2 1995/12/6
1940 Memory bug in log module fixed.
1942 --- 1.0pl1 1995/12/5
1944 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1946 Bug in Explain DatabaseInfo module fixed.
1948 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1952 The shift to v1.0 signals that we now consider the *core* functionality
1953 of YAZ reasonably stable (the core being more or less equivalent to
1954 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1955 tested (Explain not at all - though that will happen soonish).
1957 Minor changes to code to support Windows port.
1959 Various minor changes after we're getting to use GRS-1 & co. more.
1961 Added Espec-1 format.
1963 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1964 of the protocol and it cannot be selected when encoding (maps into 'string'
1965 when decoding). Needed to talk to some servers.
1967 Demo client can request simple element set names.
1969 Added Diagnostic Format encoders/decoders.
1971 Added simple Close handling to frontend server (no hooks for resource
1972 reporting yet), and demonstration client.
1974 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1976 --- 1.0b3 1995/08/24
1978 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1979 handled incorrectly when records were requested in the searchResponse. This
1980 will only affect you if you use the frontend-server.
1982 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1983 Test-client will ask for and print GRS1. Ztest will return dummy records
1986 Added Explain encoders/decoders to the service-level API. Untested.
1988 Added Extended Services: Item Order encoders and decoders to the Service-
1989 level API. Untested. We could use a recent copy of the pertinent bits
1990 of the ILL protocol to add those bits.
1992 Added diagnostic format 1 encoders/decoders to the service-level API.
1995 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1996 odr_cons.c, which causes a more correct output.
1998 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1999 was always set to 0 when no records were requested in the searchRequest.
2001 * Added better external-handling. This shouldn't harm old code that
2002 *encodes* externals. It can break code that looks for a
2003 'single-ASN1-type' representation, since those types that are known
2004 are now decoded immediately. Look at the SUTRS sample code in
2005 seshigh.c and client.c. Documentation updated.
2007 Handling of structured records in bend_fetchresponse. Length -1 marks
2008 structured record, type is deduced from format field.
2010 --- 1.0b2 1995/06/27
2011 Fairly quick maintenance release to add SUTRS support.
2013 Fixed handling of SUTRS records in the demonstration client.
2015 * Added format field to the bend_fetchrequest and bend_fetchresponce
2016 structures of the backend API (frontend server). When the record is
2017 returned, the value of the format field is mapped to an OID. The
2018 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2019 of the record. The special value VAL_NONE in the bend_request means
2020 that no specific format was requested by the client. Documentation
2021 updated accordingly. Test server (ztest) will return a fixed dummy
2022 SUTRS record if your client requests SUTRS.
2024 Documentation updated accordingly.
2026 You can now set external libraries and RANLIB support in the top-level
2030 First public release.
