1 Extended ZOOM result set options with two options that may be read by
2 a client: resultSetStatus and presentStatus with values as specified for
4 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
6 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
7 that is treated as an ItemOrder with itemRequest being an XML document
8 external. The value of "doc" is the content.
10 Extended the GFS search facility. New member of bend_search_rr
11 'estimated_hit_count' signals that hits is known to be an estmate
12 (higher or lower than real hit count). New member 'partial_resultset'
13 signals that the search was partial (hit count is lower or equal than
14 real hit count). For Z39.50, the information is stored in resultSetStatus
15 member of SearchResponse APDU. For SRU, the information is signalled
16 via SRU diagnostic 59: "Result set created with valid partial results
21 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
23 Added ZOOM_connection_peek_event.
25 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
26 the following new functions:
27 ZOOM_event_nonblock, ZOOM_connection_process,
28 ZOOM_connection_get_{socket,mask,timeout},
29 ZOOM_connection_fire_event_{timeout,socket}.
30 The existing blocking event handler, ZOOM_event, is a wrapper for the
31 + blocking ZOOM_event_sys_{poll,select}.
33 Implemented function ccl_xml_config which parses XML version of CCL
34 configuration (bug #798).
36 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
38 Added timings utility (yaz/timing.h)
42 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
45 Fixed bug #779: Rotation of apdu.log fails.
47 Fixed for character set conversions:
48 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
49 Honor G1 set in MARC-8 decoding.
53 Fixed bug #775: char conversion does not handle Alternative UTF-8
56 Implemented function yaz_marc_read_line which parses MARC line format
57 records. There is a wealth of formats out there. So far, this function
58 reads line records produced by yaz_marc_write_line.
60 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
61 more generic and easier to remember(!) options: -i format and -o format
62 which specifies input format and output format respectively - where
63 format is one of "marc", "marcxml", "line", "marcxchange".
65 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
66 does not print anything except warnings for records.
68 For yaz-marcdump, added support for MARC split into files (-s) with a given
71 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
72 spec, at http://www.loc.gov/standards/sru/record-update/
73 This has changed the binary layout of the following structs:
74 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
75 bend_update_rr . Patch by Ko van der Sloot.
77 Added GFS utility function bend_assoc_is_alive which returns 1 if
78 association is still alive (client is connected); 0 otherwise (client
79 closed connection). This allows busy servers to stop working for
82 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
83 been a separate piece of software. This version of ziffy has been modified
84 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
86 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
88 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
89 Client code may now interrogate options such as "init_opt_sort" to
90 find out whether the server claims to support various options.
94 Added utilities yaz_{set,get}_esn to set/get element set name from
97 Removed the build of libyazthread.la. The libyaz.so is the threaded version
98 of YAZ and has been so since YAZ 2.1.10.
100 Implemented ZOOM_record_error which returns error information for
101 record (surrogate diagnostic).
103 --- 2.1.38 2006/10/31
105 Updates for SRU Update by Ko van der Sloot:
106 1. Changed name from "operation" to "action"
107 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
108 versions in the code, marked as 'backward compatible'.
109 3. Added diagnostics for SRU Update.
111 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
113 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
115 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
117 For GFS, fixed problem with SRU diagnostic 'First record position out of
118 range' being issued for 0 hits.
120 zoomtst10 part of Windows Build.
122 --- 2.1.36 2006/10/13
124 Implemented yaz_filepath_comp which splits a path into file path
125 components (required by Zebra 2.0.3+).
127 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
128 BSD inspired license until now so this should not have any real impact on
129 anybody. See http://www.opensource.org/licenses/bsd-license.php
131 Fixed bug #687: Missing log lines.
133 Fixed bug #678: CQL to PQF translation does not preserve double-quote
136 Fixed bug #689: SRU diagnostics to be added.
138 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
139 whether a connection is idle (no more work do do).
141 --- 2.1.34 2006/10/04
143 Change type of optval from long to int for invocation of setsockopt with
144 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
146 Added support for specifying the max log file size for the Generic
147 Frontend Server. The size is given with option -r.
149 --- 2.1.32 2006/09/21
151 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
153 --- 2.1.30 2006/09/17
155 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
158 Fixed bug in Generic Frontend Server that could cause a server to stop
159 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
161 For the generic frontend server, the maximum record size is used as maximum
162 size of incoming packages (SRU + Z39.50). The value until was previously
163 only used in Z39.50 Init negotiation and, later, in a session controlled
164 sizes of records returned. This is controlled using -k option. It can be
165 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
167 --- 2.1.28 2006/09/04
169 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
172 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
174 New option for yaz-marcdump -lpos=value which allows setting a portion
175 of MARC header to a certain value.
177 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
179 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
180 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
182 --- 2.1.26 2006/08/15
184 Fixed problem with SRU mode type (soap, get, post) for yaz-client
187 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
189 --- 2.1.24 2006/08/08
191 Fixed MARC ISO2709 encoding routines to deal with character set
194 Minor changes to GFS logging. Database included in search request log
197 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
198 cached/multiple records.
200 Shared libraries are built by default on Unix+configure.
202 Changed cql2pqf transformation to use a different evaluation order. The
203 new order is: always, relation, structure, position, truncation, index
204 and relationModifier. Old order was: always, relation, relationModifier,
205 structure, index, position, truncation. Note that the the latter ones
206 override former ones for identical attributes.. The new scheme means that
207 it is possible to override any existing attribute with a relationModifier.
208 And also that it is possible to override everything for the index rule
209 (except the ones listed in relationModifier). No order is perfect but this
210 one, we believe, covers more real cases.. The "always" should have been
211 called "default", since the attributes there can be overridden with all
214 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
215 compilation phase, but also for yaz-config --cflags output. This allows
216 us to have public headers with Libxml2 stuff in them . It should also,
217 eventually, make Libxml2 checks redundant in packages using YAZ, such
220 --- 2.1.22 2006/06/15
222 Changed SRU update structure bend_update_rr so that SRU diagnostics are
223 stored in uri, message and details.. Previously diagnostics were stored
224 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
225 compatibility.. but he's probably the only one affected, so.
227 Added support for CCL, compiled on the client side, in ZOOM-C. This
228 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
229 input; the resulting query objects can be used for for searching with
230 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
232 YAZ' configure searches for OpenSSL by default.
234 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
235 SL_CTX_use_certificate_file. See
236 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
237 for more info. Thanks to Ko van der Sloot.
239 --- 2.1.20 2006/06/02
241 Bug #600: SRU GET, POST support for yaz-client. Introduced
242 command 'sru' which selects method SOAP/GET/POST.
244 Allow missingValueAction to be specified for the sortspec string -
245 function yaz_sort_spec. By default, the missing value action is null.
246 Use ! to specify "abort". Use = followed by stringvalue to specify default
249 Ensured that Present-handler (if defined) is called in GFS before any call to
250 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
251 searchRetrieve requests.
253 Documentation for YAZ is now based on the Docbook XML/XSLT using
254 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
255 is no longer depending on jade/openjade or docbook-to-man scripts.
256 PDF is no longer part of the distribution - but can optionally be
257 made using DSSSL/jadetex or FOP.
259 Added retrieval handling support in Generic Frontend Server to support
260 conversion between MARC/XML as well as XSLTtransforms. See
261 etc/yazgfs.xml for an example.
263 Added Authentication support to Generic Frontend Server in SRU
264 mode. Authentication using HTTP Basic is supported, as is the use
265 of 'x-username' and 'x-password' parameters in the request itself.
267 Added support for a new character set MARC8s identical to MARC8 except
268 that it converts combined characters to single Unicode characters in the
269 Latin-1 range (when possible).
271 --- 2.1.18 2006/04/24
273 ASN.1 compiler 0.4: generates brief Doxygen file header for
274 generated .h/.c files.
276 Utility yaz_iconv now supports conversion to MARC-8.
278 New facilities for the MARC module. The reading - and writing of
279 content are separate methods for the yaz_marc_t handle. The following
280 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
281 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
282 format). Write functions have prefix yaz_marc_write_.. The existing
283 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
284 available. Removed support for OAI-MARC and simplexml (not the
285 simplexml from PHP5).
287 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
288 to be returned for this connection.
290 --- 2.1.16 2006/03/31
292 Allow multiple languages and charsets to be specified with
293 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
294 negcharset iso-8859-1,utf-8
296 Translation of proximity nodes from CQL into PQF now works.
298 Moved to automake 1.8, 1.9.
300 Added function yaz_log_set_handler which allows a log handler to be
301 installed. This handler will be called for all log messages. Output
302 to file is also produced; but that can be disabled by passing NULL
303 fname to yaz_log_init_file.
305 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
307 For SRW (including GFS), accept application/soap+xml as content-type
310 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
311 produces NO stylesheet reference even if a default stylesheet is specified
314 --- 2.1.14 2006/03/14
316 Updated Windows package to include yazd.dll + yazd.lib for the
317 Development component.
319 If the environment variable YAZ_LOG is set, then it is used as a
320 string indicating the default level of logging to use if not
321 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
322 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
323 used as before. So, for example, to omit warnings from YAZ logging,
326 cql_transform() now map structure and other attributes before indexes,
327 so that index-specific structures and other attributes can override
328 defaults. So now a combination of mapping specifications such as:
330 index.dc.date = 1=date-modified 4=5
331 does the right thing.
333 cql_transform() now also respects the "always" mapping specification,
334 which establishes an initial set of attributes to be used for all
335 terms except where overridden by more specific attributes associated
336 with the index, relation or modifier.
338 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
339 which mode to use; one of "post", "get" or "soap" (SRW, default).
341 Fixes for yaz_iconv routines: changed trie-based character set conversions
342 to use only non-negative values for bit fields due to Sun's C compiler not
343 supporting negative values.
345 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
346 sequences where not read correctly. Fix by Rustam Usmanov.
348 Updated win/makefile to use options, settings which makes things
349 compile with VS C 2005.
351 --- 2.1.12 2006/02/01
353 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
355 In ZOOM socket code, use select instead of poll on MacOSX.
357 ZOOM-C now support client-side compilation of CQL into RPN that is
358 sent to the server, enabling CQL to be used against all Z39.50
359 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
360 ZOOM_query object, and submit it using ZOOM_connection_search().
361 The CQL-to-RPN translation uses a configuration file, the name of
362 which must be specified in the Connection's "cqlfile" option.
364 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
365 function, which takes as its start-term parameter a ZOOM_query object
366 (which may have had either CQL or RPN set into it).
369 --- 2.1.10 2005/11/29
371 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
372 GFS to support this as well. Backend handler, bend_srw_update, does the
373 update work. Code contributed by Ko van der Sloot.
375 Allow retrieval of Search Result-1 information in ZOOM by the use of
376 options that are attached to a result set. ZOOM documentation updated
379 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
380 UTF-8 conversion. Patch by Raj Patel.
382 Added option -m to GFS to control formatting of timestamps in log file.
384 Added 'exit' as synonym for 'quit' in yaz-client
386 Added support for specifying SRW resultSetId + resultSetIdleTime in a
387 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
388 for the new members. Patch by Ko van der Sloot.
390 Added support for SRU POST. It is supported for content-type
391 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
393 Do not build the separate Multi-threaded (MT) library libyazthread.la.
394 Instead make the library libyaz.la multi-threaded. Threading as a whole
395 can still be disabled by configure option --disable-threads. Previosly,
396 with older GLIBCs there were problems with MT libs under Apache. This
397 has now been fixed a long time ago.
399 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
402 CQL module modified to be case insensitive for relations/indexes/operations.
404 Fixed bug in CQL transform code: incorrect value relationModifieder
407 Added 'show all' command for yaz-client which retrieves all results
410 Added new yaz-client, xmles, which takes a (private) OID and
411 a document to be sent as an extended service request.
413 Describe new yaz-client commands wait_response and set_auto_wait.
415 Increase TCP/IP listener backlog from 3 (which I am guessing was
416 copied from the SunOS manual entry way back when) so SOMAXCONN, so
417 that the socket will queue as many incoming connections as it's able
418 to handle ongoing connections. In other words, it will never now
419 refuse a connection that it would be able to handle merely because
420 it's not got around to accepting() enough of the pending connections
421 yet. This is the behaviour anyway under Linux, where the listen()
422 argument is ignored; but not under BSD and on systems such as
423 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
424 YAZ-based servers should now be uniform across operating systems in
427 yaz-marcdump uses 64-bit file access on some systems. This is enabled
428 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
429 This allows yaz-marcdump to read large MARC batches (>2 GB).
431 Modified all YAZ source files - except the source which is auto-generated
432 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
435 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
436 corresponding to the existing *_setl() function. These allow option
437 values containing arbitrary valuues.
439 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
440 ZOOM_resultset_sort() in new applications. Its behaviour is identical
441 except that it returns an indicator of whether or not the sort
442 criterion was accepted (0 for OK, -1 for invalid).
446 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
447 MARC output rather than returning "new" buffer.
449 yaz-client warns about unknown init options.
451 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
455 Added support for SRW sort in Generic Frontend Server. Patch
456 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
457 sortKeys - or NULL if none is provided.
459 Fixed bug #307: It was impossible to specify indefinite/no timeout
460 for ZOOM_event. Special timeout value -1 now means indefinite timeout
463 Added support for multiple languages and charsets to be specified in
464 ZOOM. Each charset/language is separated by a blank. If negotiation is
465 in effect in init-response, Option
466 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
467 Code based on patch by Vasiliy Osadchuk.
469 Fixed bug #306: infinite recursion that occurred when calling
470 yaz_log_level_init as the first call (before other log level or
473 Fixed bug in scan handling in front end server: if preferred-Position-In-
474 Response was non-present, a NULL pointer referece was performed.
478 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
479 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
480 now defined for all those error codes. So instead of putting 109 in
481 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
482 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
484 Modified the yaz-marcdump utility to skip garbage bytes between MARC
487 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
489 Program yaz-client now exits and produces an error message if multiple
490 Z39.50 servers are specified on the command line (none or one allowed
493 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
498 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
500 Fixed bug #272: Preserve spacing for CCL terms.
504 Added support for virtual hosts and multiple backend servers for
505 the YAZ frontend server. The configution is XML based and
506 support specificition of CQL to RPN mappings and explain information.
507 See section "Virtual Hosts" in the YAZ manual.
509 Extended OPAC display utility. OPAC display utility renders
510 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
511 to supplement yaz_marc_decode_wrbuf.
513 Fixed a bug in MARC decoder that could caused it to crash for some
514 invalid MARC records. More diagnostics and warnings where added in
515 XML output (warnings, etc are stored in comments).
517 --- 2.0.34 2005/02/08
519 Fixes for UNIX domain sockets. Bug #261.
521 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
523 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
524 Added yaz_marc_subfield_str which defines subfield lead string which is
525 used in YAZ_MARC_LINE format. Default string is blank+$. Added
526 yaz_marc_endline_str which defines end of fields string used in
527 YAZ_MARC_LINE format. Default string is newline.
529 Experimental support for MarcXChange. This format can be produced
530 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
531 http://www.bs.dk/standards/MarcXchange.xsd
533 Added yaz-client commands scansize that sets maximum number of
534 entries to be returned by scan.
536 --- 2.0.32 2005/01/11
538 Added support for SRW scan in yaz-client and Generic Frontend Server.
540 * Added whereInList member to SRW Scan Term.
542 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
544 Fixed NMEM system to return aligned blocks on the smallest boundaries
545 that are suitably aligned for all possible types on the particular
546 architecture YAZ is being built for.
548 --- 2.0.30 2005/01/04
550 Fixed numerious warnings that was issued with newer versions of GCC.
552 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
553 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
556 Make YAZ Generic Frontend Server slightly faster.
558 Enhance (and reduce) logging for Generic Frontend Server.
560 Revert YAZ log system so that it flushes every write operation
561 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
563 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
564 instead of LOG_, due to name clash with syslog(3). LOG_ are still
565 present. New applications should define YAZ_USE_NEW_LOG=1 - this
566 will effectively disable old definitions.
568 --- 2.0.28 2004/11/09
570 Added yaz_log_time_format which specifies log format using
573 Added yaz_log_module_level which returns mask for a module. Value
574 is non-zero mask a if module is enabled; zero if disabled.
576 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
577 in include/yaz/cql.h.
579 Fixed bug #176: Dont throw diagnostics on empty SRU args.
581 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
583 Fixed bug #172: RPM builds does not enable SSL.
585 Doxyfile.in part of dist. Doxyfile generated by configure.
587 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
588 are given and the corresponding component does not exist.
590 Extend CCL documentation in YAZ reference. Describe r=r.
592 --- 2.0.26 2004/10/01
594 Fixed MARC->MARCXML conversion to properly deal with
595 fields, subfields, indicators having non-ASCII characters.
597 Fixed MARC->MARCXML conversion so that ASCII control characters
598 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
601 Added YAZ GFS support for conversion from Z39.50 surrogate
602 diagnostics to SRW surrogate diagnostics.
604 Bug fix: YAZ GFS did not return schema in explainResponse.
606 --- 2.0.25 2004/09/30
608 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
609 now converts recordSchema to elementSetName as well as schema URI.
611 Fixed bug in COMSTACK that prevented HTTP request packages from being
614 --- 2.0.24 2004/09/29
616 Added CCL facility r=r "range" which is similar to r=o "ordered" but
617 does not require white-space before and after the dash in a range, e.g.
618 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
621 Fixed a few AC_TRY_LINK configure tests that did not operate properly
622 due to new GCC removing "redundant" code.
624 Added yaz-client commands scanpos and scanstep that sets preferred
625 position and step-size for scan.
627 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
629 Added CCL utility ccl_qual_buf which parses one or more CCL
630 spec lines in a buffer.
632 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
633 of name and value - ignoring empty lines and comments.
635 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
637 Added odr_get_element_path which returns current element path for an
638 ODR handle. This utility is useful in error handling or user-defined
641 Added ODR_PRINT utility odr_set_stream which is is a more generic
642 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
643 to a write function and pointer to close function. The close function - if
644 non-NULL - will be called during odr_destroy.
646 Fixed bug in CCL parser where truncation char was not removed from
647 right side when truncation=both was in effect.
649 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
652 --- 2.0.23 2004/08/11
654 Fix buffer overrun in CQL parser when dealing with proximity (%).
656 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
657 to UTF-8/UCS conversion is now only based on codetables.xml.
659 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
661 --- 2.0.22 2004/08/06
663 Add support for more "commit changes" in ZOOM (uses Extended Services).
665 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
668 Yet another small fix for configure of SSL.
670 --- 2.0.21 2004/05/14
672 Fix SSL libs for configure when --with-openssl=DIR is given.
674 --- 2.0.20 2004/05/10
676 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
678 SSL comstack now uses yaz.pem certificate file on server side
679 by default. Certificate filename can be configured by calling
680 comstack function cs_set_ssl_certificate_file before cs_bind is used.
682 Fix bug regarding multiple calls to ZOOM_connection_connect.
684 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
686 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
687 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
689 ZOOM now allows inspection of X509 peer certificate for verification.
690 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
692 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
693 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
694 as "modular" but it simplifies things.
696 Added cs_get_peer_certificate to that returns peer X509 PEM.
698 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
699 NULL if SSL is unavailable.
701 Documentation about MARC decoding tools.
703 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
705 --- 2.0.19 2004/03/30
707 Rename CHANGELOG to NEWS to follow GNU style packing.
709 Fix bug with missing initialization of member in init_diagnostics.
710 This bug affects threaded version of GFS server.
712 --- 2.0.18 2004/03/20
714 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
717 Ensure zlib.dll is packed with Windows install.
719 --- 2.0.17 2004/03/17
721 Fix encoding of xsd:string to use text instead of CDATA.
723 Fix endless loop in CQL parser with unbalanced ".
725 Use a more compact way to store MARC-8 conversion tables.
727 --- 2.0.16 2004/03/16 Debian only
729 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
732 Update CQL parser to use new CQL 1.1 modifiers for booleans and
737 --- 2.0.15 2004/03/01
739 Another fix for decoding of XML packed records.
741 --- 2.0.14 2004/02/25
743 Fixes for Chunked encoding. White space not ignored after length spec.
745 Update NS and use default NS for SRW diagnostic elements.
747 --- 2.0.13 2004/02/23
749 Implement ZOOM_resultset_cache_reset which resets record cache.
751 Implement ZOOM_resultset_sort which sorts a result set.
753 Implement chunked HTTP transfer.
755 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
757 --- 2.0.12 2004/02/16
759 Added member 'schema' to bend_explain_rr structure so that backend
760 can specify explain record identifier. Defaults to Zeerex 2.0.
762 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
764 --- 2.0.11 2004/02/16
766 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
769 Added init command for yaz-client which sends "extra" init request.
771 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
772 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
774 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
776 Make ZOOM error code for "invalid query".
778 Fixed compilation for SSL which wasn't properly enabled for all platforms.
780 --- 2.0.10 2004/02/05
782 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
785 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
787 Added option -p <file> to make Generic Frontend Server to write PID file.
789 Added option -D to put Generic Frontend Server in background on its own.
791 Make ZOOM C recognize option "password". If unset, "pass" is used
792 (for backwards compatibility).
794 Fixed a bug in Generic Frontend Server that could make it crash if a
795 client sets characterSetNegotation bit, but didn't pass negotiation stuff
798 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
799 Must be issued before open, in order to be in effect.
801 --- 2.0.9-6 2004/01/12 Debian/Windows
803 Make the SRU server more picky WRT unknown params, etc.
805 Bug fix: ZOOM scan response didn't return displayTerm - when present.
807 New YAZ client command, options, that sets Z39.50 options.
809 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
810 options from a string of tokens (one token for each option bit).
812 Update SRW diagnostic code messages.
814 --- 2.0.9-5 2004/01/07 Debian/Windows
816 Handle user defined stylesheet for SRW/SRU.
818 --- 2.0.9-4 2004/01/06 Debian/Windows
820 Fix bug in decoding of Content-Length.
822 --- 2.0.9-3 2004/01/06 Debian/Windows
824 Fix a bug with decoding of XML packed records.
826 --- 2.0.9-2 2004/01/05 Debian only
828 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
830 Fix bug in SRW/SRU diagnostics decoding.
834 Fixed bug in Generic Frontend Server which could drop records exceeding
835 preferred message size. Reported and fixed by Irina Dijour.
837 Fixed calculation of package size for structured records in Generic
838 Frontend Server. Reported and fixed by Irina Dijour.
840 Fixed namespace for SRW/SRU diagnostics.
842 Fixed SEGV in yaz-client that occured for HTTP connection errors.
846 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
847 this version is incompatible with version 1.0 and older YAZ SRW/SRU
850 CQL changes to reflect recent changes to the specification:
851 * Documentation talks about context sets instead of index sets.
852 * Documentation talks about indexes instead of qualifiers.
853 * The CQL-to-PQF transformer's configuration file now uses
854 "index.set.name = <attributes>" instead of the old form
855 "qualifier.set.name = <attributes>". (Both forms are still
856 understood but the latter is deprecated.)
857 * CQL terms with no explicit index specified are now interpreted as
858 cql.serverChoice instead of srw.serverChoice (which of course
859 behaves exactly the same.)
863 MARC conversion can now generate ISO2709 output in another
864 character set. yaz-marcdump uses this facility if you invoke it
867 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
868 functions from there can be used from C++.
872 Frontend server now transfers memory from decoded packages to stream
875 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
876 references to show up.
878 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
879 the ZOOM Abstract API. The older names for the same options are still
880 also supported for the benefit of old applications.
882 ZOOM-C supports "implementationId" and "implementationVersion" options
883 to go along with "implementationName". These allow the user code to
884 specify identification strings to be sent to servers.
885 Add OID for the new ExtLite attribute set.
887 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
888 as requested/supplid by Ere Maijala <ere@atp.fi>
890 For generic frontend server, reverse the order of
891 "toolkit-supplied / application-supplied" strings sent as implementationId,
892 Name and Version. Also, remove the spaces around the slash. This brings
893 the GFS in line with the behaviour of ZOOM-C on the client side.
895 Add function ZOOM_scanset_display_term.
897 yaz-client shows scan displayTerm if present.
899 Utility yaz-iconv is now installed by default along with the man page
902 Extend configure check for OpenSSL to use pkg-config where available (such
905 Incorporate patch by Morten Bogeskov which allows a Unix file socket
906 server to specify uid/gid/mask for socket using the format
907 unix:[user=uid,][group=gid,][umask=mask,]file=path
908 If file= is omitted the existing format is assumed, e.g.
910 in which case the mask is 0666 (rw for everybody).
912 Major restructure of YAZ source. All source in libyaz is in src directory.
913 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
914 util (utility programs such as ASN.1 compiler, yaz-marcdump).
916 Added man page for utility yaz-marcdump (used to be called marcdump).
917 yaz-marcdump is installed by 'make install'.
919 Fixed a memory leak in Generic Frontend Server that occurred when decoding
920 of incoming package failed.
922 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
924 Change prototype of odr_perror: add const to message string.
926 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
928 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
929 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
930 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
931 DNS lookup. There should not be any compatibility problems with this
932 assuming that blocking=1 or 0 is used.
934 Fix bad reference in UNIX comstack in function cs_addrstr.
936 Fix for compilation on AIX.
938 The generic front-end server (server/seshigh.c) now supports returning
939 Init diagnostics to the client in User-information-field, in
940 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
945 Allow any CQL relation (not just all,any,exact,scr).
947 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
948 that features the same UI.
950 Implemented command update0 in YAZ client which is equivalent to
951 update but uses old of Ext Update ASN.1.
953 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
954 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
955 Previously no OID was used for this info.
957 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
958 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
959 returns 'malformed search term' otherwise.
961 SortResponse member resultCount now set to NULL in sort handler of
964 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
967 Add three new utility functions for translating OIDs between various
968 formats -- symbolic name such as "Usmarc", minus-1-terminated int
969 arrays and dotted strings such as "1.2.840.10003.9.5.1":
970 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
971 char *oid_to_dotstring(const int *oid, char *oidbuf);
972 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
974 Reverted modifications for ES Update definition for z_IU0Update
975 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
976 is back to YAZ 2.0.2.
978 String value attributes for CCL parser.
980 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
981 which their FirstSearch server returns in Init responses, sometimes
982 carrying useful diagnostic information when Init fails. This has the
983 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
984 "z39.50/oclcui.asn", where its definition is somewhat different from
985 what OCLC document on their web-site, as required to interoperate with
988 Support for anonymous authentication in yaz-client. Use the command
991 * Fix the OID of the Index Data-local "admin" Extended Service from
992 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
993 the 1000, which indicates a locally-defined OID, was a mistake.
997 Fix CCL directive @case handling so that it affects string match for
998 both CCL keywords and qualifiers.
1000 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1001 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1002 Decoder has been updated with ASN.1 changes as listed in
1003 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1004 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1005 z_IUUpdate, remains unchanged.
1007 ZOOM_record_get may now return a record in a specific character set.
1008 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1009 "from" is the character set of record as returned by target. "to" is
1010 the character set to be returned. If omitted, "to" is UTF-8.
1012 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1014 New ODR utility, odr_getelement, which returns name of element for
1015 which encoding/decoding failed.
1017 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1018 in cases where a required element was omitted.
1020 Bug fix: some MARC8 sequences were not converted.
1022 New ZOOM option "step" which specifies number of records to be
1023 retrieved in one chunk. Used in conjunction with "start" and "count".
1025 SRW support for yaz-client. Use scheme http: to use it, e.g.
1028 yaz-client no longer does (un)intelligent character set conversions
1029 by default. Can be enabled with charset and marc_charset commands.
1031 xmalloc trace fix for 64-bit systems such as DEC alpha.
1033 Solaris 2.6 compile fix.
1035 New function, cql_strerror() translates SRW error codes, as returned
1036 by cql_transform_error(), into human-readable English strings. Used
1037 in yaz-client diagnostics when appropriate.
1039 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1040 converts it into a type-1 query which is sent to the server. This
1041 makes CQL available for use with all Z-servers, as opposed to the tiny
1042 minority that can handle CQL queries themselves.
1044 --- 2.0.2 2003/04/28
1046 New Debian package layout similar to the Redhat Package layout.
1048 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1049 and search result respectively.
1051 --- 2.0.1 2003/04/25
1053 Redhat package is now several packages: libyaz (runtime libraries),
1054 libyaz-devel (development and documentation, and yaz (utility programs).
1055 Package spec file by Morten Bøgeskov.
1057 New member 'schema' in struct bend_fetch_rr which the name of requested
1058 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1059 handler MAY set this to reflect the schema of the returned record.
1061 New member 'display_term' in struct scan_entry. GFS now sets member entries
1062 and allocates scan entries to be filled by user scan handler. In previous
1063 version, entries member was allocated by the scan handler. That still works,
1064 but the GFS will ignore member display_term - assuming it was NOT set by
1065 the handler. The fact that the GFS now allocates the entries both allows
1066 for new members and makes a scan handler easier to write.
1068 Fix CQL lex buffer overflow.
1070 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1071 SRU default recordPacking is string.
1073 SRU protocol support for frontend server.
1075 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1077 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1079 Added scan for the ZOOM shell (zoomsh).
1083 * String Identifers for Schemas (Amendment 5).
1084 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1085 Old definition for schema
1086 Odr_oid *schema; /* OPT */
1091 Z_InternationalString *uri;
1092 #define Z_Schema_oid 1
1093 #define Z_Schema_uri 2
1096 * resultCount parameter to Sort Response (Amendment 1).
1097 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1099 Support for SRW 1.0 over HTTP. This is an optional feature and
1100 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1103 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1104 on the same port. SRW SearchRetrieveRequests are mapped
1105 to bend_init,bend_search,bend_fetch,bend_close.
1107 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1109 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1110 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1112 ZOOM connections are SRW based if schem http is used for hostname
1113 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1114 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1116 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1117 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1118 distance=n, order=true/false, relation=le, prox unit=word. If
1119 n is omitted, distance 1 is used.
1121 Fixed problem with C compiler include path in wrong order.
1123 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1124 on Solaris. Patch from Ko van der Sloot.
1126 New MARC decode API. All new functions operate on a yaz_marc_t
1127 handle. The most important new functions are: yaz_marc_create,
1128 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1129 decode and destroy respectively. Decoder can produce formats
1130 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1131 include/yaz/marcdisp.h.
1133 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1134 to UTF-8, UCS-32, wchar_t or Latin-1.
1136 * Prototypes for yaz_iconv_-functions moved to separate header
1137 include/yaz/yaz-iconv.h.
1139 Make a few private functions 'static' in unix.c. This prevents
1140 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1142 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1143 are set when Init Response is received.
1145 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1146 but returns diagnostic set as well.
1148 New function yaz_strerror which is a portable wrapper for
1149 strerror/strerror_r/GetLastMessage.
1151 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1152 is returned for MARC. If type is "oai", then OAI MARC is returned.
1154 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1157 --- 1.9.2 2002/11/26
1159 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1161 Fix bad race conditions on SIGTERM and terminate gracefully in
1164 Move retrieval (data1) module to Zebra since nobody seems to be
1167 Add GRS-1 render for ZOOM using same format as yaz-client.
1169 --- 1.9.1 2002/10/05
1171 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1173 Fix broken ESpec handling in data1 module.
1175 SGML reader parses comments and makes them part of the data1 tree.
1177 Added several type casts so that YAZ compiles as C++ code.
1179 ZOOM didn't handle PDU encoding failures properly.
1181 Added more Bib-1 diagnostics (approved extensions).
1183 GNU configure: better check for iconv.
1185 More portable use of accept, getpeername. Check for socklen_t. Use
1186 int/size_t if socklen_t is not defined.
1190 PQF parser rejects bad queries - including those with extra
1191 characters in them. PQF parser used to silently ignore that.
1192 Cleaner API for PQF added, which allows you to get detailed
1193 error information for bad queries (see yaz/pquery.h).
1195 Fixed bug in ZOOM_record_get for type "database".
1197 Implemented mini iconv library supporting conversions between
1198 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1200 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1202 --- 1.8.9 2002/08/20
1204 Fixed ZOOM C record cache so that preferredRecordSyntax and
1205 elementSetName is used to check for already fetched records.
1207 --- 1.8.8 2002/08/02
1209 Added three members in bend_initrequest structure to facilitate
1210 character set negotiation.
1212 Fixed a bug in frontend server that could cause indefinite
1213 loops under rare conditions.
1215 Revised character set utilities (charneg.h) so that encoding
1216 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1218 For PQF, directive @term <type> sets term type for Scan/Search.
1219 Here <type> is general, string, numeric, null. The term type
1220 is inherited - just like @attr.
1222 New call odr_set_charset that sets character set conversion for
1223 international-strings on a ODR stream. Prototype is:
1224 int odr_set_charset(ODR o, const char *to, const char *from);
1225 The InternationalString is still represented as C string in YAZ
1226 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1227 won't). On the protocol level, you can use any encoding.
1229 Support for UNIX sockets in ZOOM.
1231 Solaris recv sometimes returns errno == ENOENT. It is treated as
1232 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1234 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1235 both client and server. Code by Morten Bøgeskov.
1237 --- 1.8.7 2002/05/22
1239 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1240 that they can be used directly from Visual Basic. You must recompile
1241 your windows APP if you're using ZOOM.
1243 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1244 Commands "lang" and "charset" sets language and character set respectively.
1245 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1246 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1248 Attributes from multiple CCL fields may be OR'ed rather than merged
1249 using directive "@field or". Fields are still merged by default -
1250 equivalent to "@field merge".
1252 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1255 Fixed bug in zget for parameter ExtendedServicesResponse.
1259 --- 1.8.6 2002/03/25
1261 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1263 Client displays USR.1:SearchResult-1 (hits per term).
1265 Additional Search Info for search in Generic Frontend Server.
1267 Fixed CCL parsing of "field=s".
1269 WIN32 installer - using the excellent NSIS software from nullsoft.
1271 Fixed CCL parsing of "field = - <number>".
1273 Added function yaz_marc_decode that decodes MARC for line mode
1274 display or XML (similar to that used by JZKit).
1276 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1277 Z39.50. But ISO/ILL was, however.
1279 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1280 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1285 --- 1.8.5 2002/02/03
1287 New YAZ client features: Command completion and new commands:
1288 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1289 Code provided by Jacob Poulsen.
1291 New call oid_trav, that visits all registered OIDs via callback.
1293 Function ZOOM_record_get now returns const char pointer rather than
1294 void pointer. It saves a lot of type casts.
1296 For YAZ client, command "auth" now allows you to set authentication
1297 in IdPass style. It is enabled when three tokens are given - order
1298 is user, group and password.
1300 Fix memory leaks in MARC record handling for ZOOM.
1302 New option for YAZ client, -k <kilobytes> that sets
1303 maximum record size. Similar to -k option for generic frontend
1304 server and yaz-ztest.
1306 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1308 Prefix query parser reports "fail" when bad attribute set is given.
1310 Fix in MARC decoder. Proximity logging. Fix for attribute set
1311 in scan handler for server. Patches by Shigeru Ishida.
1313 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1316 Configure option --with-openssl=<dir> now works when a directory is
1317 specified. Patch provided by Morten Bøgeskov.
1319 New option for YAZ client, -u <auth>, that sets authentication.
1321 ZOOM fix: error information was sometimes "missing", since error
1322 was cleared/reset too when it shouldn't.
1324 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1326 --- 1.8.4 2002/01/04
1328 Scan for ZOOM API. New object ZOOM_scanset. New functions
1329 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1330 ZOOM_scanset_destroy.
1332 New ZOOM function, ZOOM_connection_last_event, that returns type
1333 of last event (such as "receive data", "send data", "apdu received",
1336 New ZOOM option, schema, that specifies schema for retrieval.
1338 New CCL feature. Qualifiers can be aliases for one or more
1339 other qualifiers (if more than one is given, OR is used).
1341 ZOOM uses named result sets if target supports it.
1343 Two new YAZ client commands: . (dot, which sources a script of YAZ
1344 client commands), and ! (to execute shell command.). Implemented
1347 Working on Debian packages.
1349 --- 1.8.3 2001/11/19
1351 YAZ client enables named result sets only if target supports it.
1353 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1355 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1356 with key="host" to get same result.
1358 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1359 Function Z3950_resultset_record(s) returns references to records
1360 "owned" by resultset. To become owner use Z3950_record_clone.
1362 Function z_ext_record handles Extended Services. Thanks to
1365 --- 1.8.2 2001/11/12
1367 CCL Parser fix: ignore token comma when dealing with and-lists.
1369 Documentation updates for COMSTACK.
1371 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1372 Changed prototype Z3950_records. For some functions, int parameters
1373 were changed to size_t.
1375 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1378 New MARC decode/display function, marc_display_exl, which properly rejects
1379 non-ISO2709 records. YAZ client uses it.
1381 --- 1.8.1 2001/10/29
1383 Fix bug: local attribute set wasn't set correctly in PQF strings.
1387 * Old Z39.50 codecs no longer supported.
1389 Added ZOOM C binding. See http://zoom.z3950.org/
1391 Renamed states for COMSTACKs to avoid confusion with events.
1393 Implemented cs_look and proper cs_rcvconnect.
1395 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1397 Configure detects POSIX threads on OpenBSD.
1399 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1400 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1402 When error is returned from present handler, non-surrogate diagnostic
1403 is returned in present response (and fetch handler is no longer called).
1405 * Minor adjustments to pquery parser (PQF). Token characters may be
1406 escaped by using backslash (C-style).
1408 PQF parser allows string attribute values to be specified. For @attr,
1409 non-numeric characters after the equal-sign are treated as strings
1410 (e.g. @attr 9=title).
1412 CCL trunction character may be defined (@truncation in file)
1414 * function zget_ExtendedServicesRequest sets waitAction to
1415 waitIfPossible (was wait).
1417 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1420 CCL operator names may be set in field definition files (CCL_bibset).
1421 See ccl/bib1 for an example.
1423 Fixes in ASN.1 compiler for C++ compatibility.
1425 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1426 and "op_or" to avoid conflict with C++.
1428 Fixed problem with GNU readline detection on Redhat 7.0.
1430 Added step-size for Scan backend handler.
1432 Fixed bug that made the frontend server crash when no attribute
1433 set was specified for scan.
1435 Front-end server automatically switches to original working directory
1436 when installed as an NT service. Previously -w had to be specified to
1439 Added extended attributes for retrieval module (data1), so that data1
1440 records carry d1_readXML/SGML attributes. d1_read also supports
1441 null-data rules ( <tag/>)
1443 On UNIX when POSIX threads are available, a separate library libyazthread
1444 is created. Programmers should link with that library and the yaz library
1445 when using threads. The reason for the split was that some applications
1446 on Linux, such as Apache, doesn't work well when using shared objects that
1449 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1450 (or any frontend server) in SSL mode by specifying ssl: followed by
1451 address. Only tested on UNIX.
1453 Added feature for CCL module. Virtual structure s=al or s=ol generates
1454 and-list and or-list respectively instead of phrase search.
1458 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1459 log_mask_str. This was done to avoid name conflicts with other libraries
1460 (such as other PHP extensions).
1462 Added raw OID member for preferred record syntax (request_format_raw)
1463 and returned record syntax (output_format_raw) for backend fetch method.
1465 Config file yaz-config now accepts options so that it returns specific
1466 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1468 Shared library support for UNIX using GNU libtool.
1470 * Modified backend interface. Request/Response struct's replaced by
1471 one read/write C struct. For example bend_fetchrequest and
1472 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1473 Every handler - even search has to be registered in bend_init
1474 handler. This means that the YAZ library no longer refers to
1475 external functions and it makes it possible to make the whole
1476 thing a single DLL/SO.
1478 Added Segment handler for backend server.
1480 Added Zmbol/Zebra administrative functions to YAZ client.
1482 Threaded frontend server on UNIX (when POSIX Threads are available).
1483 Starting the server with option -T enables multi-threading.
1487 Added configure option --enable-comp/disable-comp to control use
1488 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1489 located in sub directory asn.
1491 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1492 in ${exec_prefix}/bin along with the other programs yaz-client and
1495 GNU automake used to maintain makefiles.
1497 Added several OID's.
1499 Changed retrieval module so that we can load records with no abstract
1500 syntax defined. Tagpaths in these records are fully composed of string
1503 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1507 On UNIX, the generated makefile now supports a proper 'make install'.
1508 The prefix can be set via GNU configure to set the install location
1509 (default is /usr/local).
1511 * YAZ programs client and ztest were renamed to yaz-client and
1512 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1513 locations, such as /usr/bin,/usr/local/bin,etc.
1515 * YAZ Header files were moved from include to include/yaz. YAZ Header
1516 files are referred to as include <yaz/log.h> rather than <log.h>.
1517 The YAZ include path (-I ..) is therefore the same as before. Programmers
1518 should update their #include statements or use -Ipath/include/yaz
1519 instead. The main motivation for doing this change is that YAZ header files
1520 can be installed in "standard" locations /usr/include,/usr/local/include
1521 without introducing conflicts, since ALL YAZ header files are stored
1522 in subdirectory yaz (under /usr/include for example).
1524 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1525 rather than project/workspace files. We switched because project files
1526 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1529 Changed name of logging function, logf, to yaz_log, to prevent name
1530 clash with some math-log functions. The YAZ header log.h defines logf
1531 to yaz_log (#define) so there should be no incompatibilities by this
1534 Added bend_start/bend_stop handlers for server. These handler are
1535 called on start/stop of server. For windows they are called whenever
1536 a service is started/stopped.
1538 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1539 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1540 in util/yc.tcl. The auto-generated C code structures are, in a few
1541 cases, incompatible with the old decoders. There are differences in the
1542 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1543 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1544 The preprocessor variable ASN_COMPILED is defined when the compiled
1545 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1546 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1547 wish to use the old encoders/decoders you can specify --disable-yc
1550 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1551 version so that it supports both new - and old version of DB Update
1553 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1554 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1555 change. The name parameter can be set to 0 in which no name is specified
1556 for the construction. The macros odr_implicit and odr_explicit sets name
1557 parameter to zero for the construction involved. New macros
1558 odr_implicit_tag and odr_explicit_tag are similar to the others,
1559 except that a name parameter is added. For programmers' that don't use
1560 ODR they probably only need to change the call to z_APDU and z_External.
1562 Added access control facility by interfacing the TCP wrapper library.
1563 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1564 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1565 name of the daemon and enables the access control as specified in
1566 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1568 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1569 den Dool <H.M.vdnDool@kub.nl>.
1571 Added reference ID parameter to most functions in server API - refer
1572 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1574 Changed name of ccl library to libccl.a (was ccl.a).
1576 Fixed bug in decoder for Explain (Category TargetInfo).
1578 Added support for GNU readline in client. Thanks to Jacob Poulsen
1579 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1581 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1582 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1583 IMPLEMENTATION! This change was made to the development version before
1584 the ZIG decided to retract the amendment. If any users MUST be
1585 compatible with the original Update definition, PLEASE CONTACT US, and
1586 we will include a separate definition corresponding to the old Update
1587 ES. Note that because of the change to the ASN.1 of the
1588 TaskPackageRecordStructure we cannot define a single structure that
1589 will support both versions.
1591 * Added const modifier to buffer parameter for some ODR/BER encoding
1592 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1593 completeWAIS, odr_dumpBER.
1595 Fixed bug in client.c which caused a crash when a scanResponse didn't
1596 contain positionOfTerm.
1598 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1599 * will cause an error in a client if a non-YAZ target sends both a
1600 * list of Scan entries and non-surrogate diagnostics.
1602 Retrieval module enhancements. Tag sets may be typed in the reference
1603 to it. From the .abs-file the "tagset" directive takes a third optional
1604 integer type for the tag set referenced. From a .tag-file the "include"
1605 directive takes a third optional type as well. The old "type" directive
1606 in the tag set itself is still recognized but acts as the default type
1609 Backend interface change. Individual Scan terms returned from bend_scan
1610 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1611 in include/backend.h.
1613 Retrieval module enhancements. Multiple tag sets and attribute sets may
1614 be specified in abstract syntax specs. Revised the error/warning for
1615 logging messages reported by the retrieval module when reading the
1618 Object Identifier system (oid_..) changed. The API is backwards
1619 compatible but the oid-routines now allocates new OID's when needed.
1620 Raw OID's may be specified in oid_getvalbyname.
1622 YAZ now uses GNU configure to generate Makefile(s).
1624 * Minor changes in some of the member names of DeleteResultSetRequest and
1625 DeleteResultSetResponse. See include/proto.h.
1627 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1628 and added member 'languages' in TargetInfo (which was missing).
1630 Changed the way attribute sets are handled in the retrieval
1631 module. These are now cached, just like the abstract syntaxes
1634 Changed YAZ so that it links with compiled ASN.1.
1636 Added Explain-schema definitions and mapping routines. The following
1637 Explain categories have been implemented: AttributeDetails,
1638 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1640 Fixed minor bug in Windows version of Server Library.
1642 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1644 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1646 Added EXTERNAL: UNIverse Resource Report (non-standard).
1648 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1649 ENUMERATED and SET OF.
1651 * Added 'const' to some of the char pointer arguments for the
1652 functions, data1_read_node, data1_getelementbytagname,
1653 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1656 Fixed bug in data1_insert_taggeddata - the last_child member of
1657 parent wasn't initialised.
1659 * Changed data1_read_record and data1_read_node so that the supplied
1660 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1661 doesn't refer to any parts of the "SGML"-buffer.
1663 Fixed bug in server library (Windows version of statserv_remove).
1665 * Changed code so that it compiles as C++. The type definition
1666 of Odr_fun which is a member of Odr_arm was changed. The result is,
1667 that an explicit typecast is needed for the fun pointer when
1668 using Odr_arm - as in:
1669 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1671 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1673 Implemented the new structured date and time definition as approved
1674 by the ZIG. Added schemaId element to the specificTag in Espec-1
1675 (also approved at the last ZIG). Thanks to RVDM.
1677 Added some Object identifiers (RVDM).
1679 Changed the Update Extended Service (RVDM).
1681 Added command "refid" to client which specifies referenceId for
1682 the following requests.
1684 Implemented extended service handling for server. See ztest.c
1685 for an example as well as backend.h. New handlers are registerd
1686 in the Init handler.
1688 * Changed interface for sort in server.
1690 Added new members to statserv_options_block. It allows a server
1691 to read options from another source than just the command line. Thanks
1692 to Charles Woodfield.
1694 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1695 renamed to zboolean. Some C++ compilers complained about the name.
1697 Minor changes to gils.abs. Added index 's' (sort) on title
1698 and date/time-last-modified.
1700 --- 1.4pl2 1998/1/30
1702 Fixed bug in server library regarding inetd mode (-i). This bug
1703 was introduced by release 1.4.
1705 --- 1.4pl1 1998/1/29
1707 Added sort facility in client and backend server interface.
1709 Fixed problem with dependencies in Makefile(s).
1711 Fixed bugs for encoders/decoders of extended services and
1714 Implemented sub-tree feature for schemas. Sub-trees are
1715 referenced in *.abs-files. See explain.abs for an example
1716 of the use of this feature.
1718 Modified bib1.att; local attributes for ANY didn't include
1719 ANY itself (only affects use of the retrieval module).
1721 Fixed bug in plain SGML reader in function data1_read_node:
1722 tags with prefix "var" was incorrectly interpreted as variants.
1724 Added feature "sub-schemas" to enable references to - and definitions
1725 of - group of elements.
1727 * Removed member parent from type data1_element (in data1.h).
1729 Implemented function odr_nullval() that returns the value of
1732 * Removed member num_children from data1_node (in data1.h).
1734 Made NT service interface part of the server library. The
1735 function statserv_main uses the NT service when required and
1736 calls the statserv_start / statserv_close routines.
1738 Routine zget_SearchRequest and zget_PresentRequest fills
1739 resultSetName/Id member with "default" instead of "Default".
1741 Fixed memory leak in server. Request queue member wasn't freed.
1743 Fixed nmem_exit so that memory is freed.
1747 Revised the CCL parser utility to be thread safe.
1749 Added function, oid_ent_to_oid, to replace the function
1750 oid_getoidbyent, which is not thread safe.
1752 * Added nmem_init and nmem_exit to initialize and release
1753 NMEM resources. Function nmem_init should be called once in the
1754 initial thread before NMEM/ODR is used. statserv.c and client.c
1755 have been changed accordingly. The change was necessary to make
1756 NMEM thread safe. The NMEM memory pool is shared amongst threads
1757 in a process. Unix-based applications will still work fine without
1760 Added NT Services interface for the the Z39.50 (statserv) Server.
1761 Refer to the ztest.c source on the usage.
1763 Windows 95/NT port using MSVC5.0. Project files are included in the
1766 * Defined new 'global' handle for the retrieval (data1) system. The
1767 new handled, data1_handle, describes the state of the data1 system.
1768 This handle is passed as first argument to virtually all
1769 data1 related routines. The functions data1_create and data1_destroy
1770 creates and destroys a data1 handle respectively.
1772 Added ODR encode stream member to all backend request structures
1773 init, search, scan etc. This stream should be used to allocate all
1774 memory used for the response when thread safe operation is needed.
1776 Changed the comstack utility, cs_addstr, to be thread safe. The
1777 returned hostname string returned by the function is now part the
1780 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1781 function. The cs_straddr takes a COMSTACK handle as argument, so this
1782 function must be used after cs_create and before bind/connect.
1783 This function is thread safe.
1785 Moved test server to 'ztest' directory - generic server code still
1786 in 'server' directory.
1788 Made prefix query (pquery.c) utility thread safe.
1790 Added new function modifier YAZ_EXPORT to 'export' public DLL
1791 functions when using windows (see include/yconfig.h).
1793 Added definitions to the OID database (util/oid.c) (RVDM).
1795 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1797 Added call to ccl_rpn_delete in client program.
1799 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1800 release of RPN structure.
1802 Added support for C++, headers uses extern "C" for public definitions.
1803 With input from RVDM.
1805 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1806 Thanks to Ronald van der Meer (RVDM).
1808 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1810 Added support for private extensions to the OID database
1811 (oid_setprivateoids()). Thanks to RVDM.
1813 Added optional, physical ANY (key replication)
1815 Fixed null-reference problem in GRS-1 output filter.
1817 Proximity operator added to Prefix Query Format (PQF).
1819 In test client command "base" accepts multiple databases.
1821 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1825 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1827 Smallish bug-fixes in the new encoders/decoders (explain).
1829 Bug fixed in DeleteRequest.
1831 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1833 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1835 Added SOIF syntax (using private OID for now) to retrieval module and client.
1837 Added Update extended service.
1839 Added SearchResult-1 additional info structure.
1841 Added optional CCL (ISO8777) interpreter as separate module. Available
1844 --- 1.2 1996/6/10 (1st anniversary release)
1846 Added Summary record syntax. Lightly tested.
1848 Added OPAC record syntax. Untested.
1850 Added ResourceReport service encoders/decoders. Untested.
1852 Fixed bug in z_Unit - wrong tagging on unitSystem.
1854 Fixed bug in the DiagRecs decoder.
1856 Added options for max PDU size and session timeout to frontend-server.
1858 Added documentation of query-language parsers and other supporting utilities.
1860 [frontend-server] Added Attribute set to the bend_scanrequest API.
1862 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1863 surrogate diagnostics were generated.
1865 [retrieval] Allow multiple local values for attribute.
1867 [retrieval] Allow multiple attributes per element in .abs files. index type.
1869 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1871 --- 1.1pl2 1996/4/10
1873 Minor changes, mostly specific to Zebra's requirements (retrieval)
1877 Repaired bug in frontend server when running multiple listening
1878 endpoints in dynamic mode.
1880 z_External() now won't break if a known, ASN.1 value comes encapsulated
1881 in an octet-string. The value will pass through unmodified in an Odr_oct.
1883 Added a bit of code to the demo client to decode & display
1884 ASN.1-structured records represented in the octet-aligned branch of
1885 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1887 Added z_ext_getentbyref() to the ASN module. Doc updated.
1889 * Completed the SCAN definition in the ASN module. This may break SCAN
1890 code based on older YAZ-versions at compile-time. The fix is easy -
1893 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1894 under the SCAN definition. Remember to initialize this, server-people.
1896 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1897 that this does not extend to ODR and ASN.
1899 Comstack allows insertion of established socket (primarily for
1900 inetd-operation of servers). Doc updated.
1902 Front-end server can now start from the inetd in TCP mode. Doc
1905 --- 1.0pl4 1996/1/24
1909 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1910 the rank and record number.
1912 Adjustments to the frontend server.
1914 Fixed diagnostic BER dumper. It ignored the file argument.
1918 Various changes to retrieval module.
1920 Changed the union discriminators of the protocol files from enums to
1921 ints paired with #defines.
1923 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1926 *Changed operator in the RPN structure to 'roperator', again to avoid a
1929 Fixed problems in Explain decoders/encoders.
1931 --- 1.0pl2 1995/12/6
1933 Memory bug in log module fixed.
1935 --- 1.0pl1 1995/12/5
1937 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1939 Bug in Explain DatabaseInfo module fixed.
1941 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1945 The shift to v1.0 signals that we now consider the *core* functionality
1946 of YAZ reasonably stable (the core being more or less equivalent to
1947 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1948 tested (Explain not at all - though that will happen soonish).
1950 Minor changes to code to support Windows port.
1952 Various minor changes after we're getting to use GRS-1 & co. more.
1954 Added Espec-1 format.
1956 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1957 of the protocol and it cannot be selected when encoding (maps into 'string'
1958 when decoding). Needed to talk to some servers.
1960 Demo client can request simple element set names.
1962 Added Diagnostic Format encoders/decoders.
1964 Added simple Close handling to frontend server (no hooks for resource
1965 reporting yet), and demonstration client.
1967 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1969 --- 1.0b3 1995/08/24
1971 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1972 handled incorrectly when records were requested in the searchResponse. This
1973 will only affect you if you use the frontend-server.
1975 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1976 Test-client will ask for and print GRS1. Ztest will return dummy records
1979 Added Explain encoders/decoders to the service-level API. Untested.
1981 Added Extended Services: Item Order encoders and decoders to the Service-
1982 level API. Untested. We could use a recent copy of the pertinent bits
1983 of the ILL protocol to add those bits.
1985 Added diagnostic format 1 encoders/decoders to the service-level API.
1988 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1989 odr_cons.c, which causes a more correct output.
1991 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1992 was always set to 0 when no records were requested in the searchRequest.
1994 * Added better external-handling. This shouldn't harm old code that
1995 *encodes* externals. It can break code that looks for a
1996 'single-ASN1-type' representation, since those types that are known
1997 are now decoded immediately. Look at the SUTRS sample code in
1998 seshigh.c and client.c. Documentation updated.
2000 Handling of structured records in bend_fetchresponse. Length -1 marks
2001 structured record, type is deduced from format field.
2003 --- 1.0b2 1995/06/27
2004 Fairly quick maintenance release to add SUTRS support.
2006 Fixed handling of SUTRS records in the demonstration client.
2008 * Added format field to the bend_fetchrequest and bend_fetchresponce
2009 structures of the backend API (frontend server). When the record is
2010 returned, the value of the format field is mapped to an OID. The
2011 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2012 of the record. The special value VAL_NONE in the bend_request means
2013 that no specific format was requested by the client. Documentation
2014 updated accordingly. Test server (ztest) will return a fixed dummy
2015 SUTRS record if your client requests SUTRS.
2017 Documentation updated accordingly.
2019 You can now set external libraries and RANLIB support in the top-level
2023 First public release.
