1 Extended the GFS search facility. New member of bend_search_rr
2 'estimated_hit_count' signals that hits is known to be an estmate
3 (higher or lower than real hit count). New member 'partial_resultset'
4 signals that the search was partial (hit count is lower or equal than
5 real hit count). For Z39.50, the information is stored in resultSetStatus
6 member of SearchResponse APDU. For SRU, the information is signalled
7 via SRU diagnostic 59: "Result set created with valid partial results
12 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
14 Added ZOOM_connection_peek_event.
16 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
17 the following new functions:
18 ZOOM_event_nonblock, ZOOM_connection_process,
19 ZOOM_connection_get_{socket,mask,timeout},
20 ZOOM_connection_fire_event_{timeout,socket}.
21 The existing blocking event handler, ZOOM_event, is a wrapper for the
22 + blocking ZOOM_event_sys_{poll,select}.
24 Implemented function ccl_xml_config which parses XML version of CCL
25 configuration (bug #798).
27 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
29 Added timings utility (yaz/timing.h)
33 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
36 Fixed bug #779: Rotation of apdu.log fails.
38 Fixed for character set conversions:
39 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
40 Honor G1 set in MARC-8 decoding.
44 Fixed bug #775: char conversion does not handle Alternative UTF-8
47 Implemented function yaz_marc_read_line which parses MARC line format
48 records. There is a wealth of formats out there. So far, this function
49 reads line records produced by yaz_marc_write_line.
51 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
52 more generic and easier to remember(!) options: -i format and -o format
53 which specifies input format and output format respectively - where
54 format is one of "marc", "marcxml", "line", "marcxchange".
56 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
57 does not print anything except warnings for records.
59 For yaz-marcdump, added support for MARC split into files (-s) with a given
62 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
63 spec, at http://www.loc.gov/standards/sru/record-update/
64 This has changed the binary layout of the following structs:
65 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
66 bend_update_rr . Patch by Ko van der Sloot.
68 Added GFS utility function bend_assoc_is_alive which returns 1 if
69 association is still alive (client is connected); 0 otherwise (client
70 closed connection). This allows busy servers to stop working for
73 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
74 been a separate piece of software. This version of ziffy has been modified
75 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
77 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
79 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
80 Client code may now interrogate options such as "init_opt_sort" to
81 find out whether the server claims to support various options.
85 Added utilities yaz_{set,get}_esn to set/get element set name from
88 Removed the build of libyazthread.la. The libyaz.so is the threaded version
89 of YAZ and has been so since YAZ 2.1.10.
91 Implemented ZOOM_record_error which returns error information for
92 record (surrogate diagnostic).
96 Updates for SRU Update by Ko van der Sloot:
97 1. Changed name from "operation" to "action"
98 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
99 versions in the code, marked as 'backward compatible'.
100 3. Added diagnostics for SRU Update.
102 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
104 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
106 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
108 For GFS, fixed problem with SRU diagnostic 'First record position out of
109 range' being issued for 0 hits.
111 zoomtst10 part of Windows Build.
113 --- 2.1.36 2006/10/13
115 Implemented yaz_filepath_comp which splits a path into file path
116 components (required by Zebra 2.0.3+).
118 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
119 BSD inspired license until now so this should not have any real impact on
120 anybody. See http://www.opensource.org/licenses/bsd-license.php
122 Fixed bug #687: Missing log lines.
124 Fixed bug #678: CQL to PQF translation does not preserve double-quote
127 Fixed bug #689: SRU diagnostics to be added.
129 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
130 whether a connection is idle (no more work do do).
132 --- 2.1.34 2006/10/04
134 Change type of optval from long to int for invocation of setsockopt with
135 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
137 Added support for specifying the max log file size for the Generic
138 Frontend Server. The size is given with option -r.
140 --- 2.1.32 2006/09/21
142 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
144 --- 2.1.30 2006/09/17
146 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
149 Fixed bug in Generic Frontend Server that could cause a server to stop
150 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
152 For the generic frontend server, the maximum record size is used as maximum
153 size of incoming packages (SRU + Z39.50). The value until was previously
154 only used in Z39.50 Init negotiation and, later, in a session controlled
155 sizes of records returned. This is controlled using -k option. It can be
156 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
158 --- 2.1.28 2006/09/04
160 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
163 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
165 New option for yaz-marcdump -lpos=value which allows setting a portion
166 of MARC header to a certain value.
168 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
170 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
171 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
173 --- 2.1.26 2006/08/15
175 Fixed problem with SRU mode type (soap, get, post) for yaz-client
178 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
180 --- 2.1.24 2006/08/08
182 Fixed MARC ISO2709 encoding routines to deal with character set
185 Minor changes to GFS logging. Database included in search request log
188 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
189 cached/multiple records.
191 Shared libraries are built by default on Unix+configure.
193 Changed cql2pqf transformation to use a different evaluation order. The
194 new order is: always, relation, structure, position, truncation, index
195 and relationModifier. Old order was: always, relation, relationModifier,
196 structure, index, position, truncation. Note that the the latter ones
197 override former ones for identical attributes.. The new scheme means that
198 it is possible to override any existing attribute with a relationModifier.
199 And also that it is possible to override everything for the index rule
200 (except the ones listed in relationModifier). No order is perfect but this
201 one, we believe, covers more real cases.. The "always" should have been
202 called "default", since the attributes there can be overridden with all
205 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
206 compilation phase, but also for yaz-config --cflags output. This allows
207 us to have public headers with Libxml2 stuff in them . It should also,
208 eventually, make Libxml2 checks redundant in packages using YAZ, such
211 --- 2.1.22 2006/06/15
213 Changed SRU update structure bend_update_rr so that SRU diagnostics are
214 stored in uri, message and details.. Previously diagnostics were stored
215 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
216 compatibility.. but he's probably the only one affected, so.
218 Added support for CCL, compiled on the client side, in ZOOM-C. This
219 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
220 input; the resulting query objects can be used for for searching with
221 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
223 YAZ' configure searches for OpenSSL by default.
225 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
226 SL_CTX_use_certificate_file. See
227 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
228 for more info. Thanks to Ko van der Sloot.
230 --- 2.1.20 2006/06/02
232 Bug #600: SRU GET, POST support for yaz-client. Introduced
233 command 'sru' which selects method SOAP/GET/POST.
235 Allow missingValueAction to be specified for the sortspec string -
236 function yaz_sort_spec. By default, the missing value action is null.
237 Use ! to specify "abort". Use = followed by stringvalue to specify default
240 Ensured that Present-handler (if defined) is called in GFS before any call to
241 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
242 searchRetrieve requests.
244 Documentation for YAZ is now based on the Docbook XML/XSLT using
245 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
246 is no longer depending on jade/openjade or docbook-to-man scripts.
247 PDF is no longer part of the distribution - but can optionally be
248 made using DSSSL/jadetex or FOP.
250 Added retrieval handling support in Generic Frontend Server to support
251 conversion between MARC/XML as well as XSLTtransforms. See
252 etc/yazgfs.xml for an example.
254 Added Authentication support to Generic Frontend Server in SRU
255 mode. Authentication using HTTP Basic is supported, as is the use
256 of 'x-username' and 'x-password' parameters in the request itself.
258 Added support for a new character set MARC8s identical to MARC8 except
259 that it converts combined characters to single Unicode characters in the
260 Latin-1 range (when possible).
262 --- 2.1.18 2006/04/24
264 ASN.1 compiler 0.4: generates brief Doxygen file header for
265 generated .h/.c files.
267 Utility yaz_iconv now supports conversion to MARC-8.
269 New facilities for the MARC module. The reading - and writing of
270 content are separate methods for the yaz_marc_t handle. The following
271 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
272 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
273 format). Write functions have prefix yaz_marc_write_.. The existing
274 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
275 available. Removed support for OAI-MARC and simplexml (not the
276 simplexml from PHP5).
278 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
279 to be returned for this connection.
281 --- 2.1.16 2006/03/31
283 Allow multiple languages and charsets to be specified with
284 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
285 negcharset iso-8859-1,utf-8
287 Translation of proximity nodes from CQL into PQF now works.
289 Moved to automake 1.8, 1.9.
291 Added function yaz_log_set_handler which allows a log handler to be
292 installed. This handler will be called for all log messages. Output
293 to file is also produced; but that can be disabled by passing NULL
294 fname to yaz_log_init_file.
296 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
298 For SRW (including GFS), accept application/soap+xml as content-type
301 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
302 produces NO stylesheet reference even if a default stylesheet is specified
305 --- 2.1.14 2006/03/14
307 Updated Windows package to include yazd.dll + yazd.lib for the
308 Development component.
310 If the environment variable YAZ_LOG is set, then it is used as a
311 string indicating the default level of logging to use if not
312 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
313 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
314 used as before. So, for example, to omit warnings from YAZ logging,
317 cql_transform() now map structure and other attributes before indexes,
318 so that index-specific structures and other attributes can override
319 defaults. So now a combination of mapping specifications such as:
321 index.dc.date = 1=date-modified 4=5
322 does the right thing.
324 cql_transform() now also respects the "always" mapping specification,
325 which establishes an initial set of attributes to be used for all
326 terms except where overridden by more specific attributes associated
327 with the index, relation or modifier.
329 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
330 which mode to use; one of "post", "get" or "soap" (SRW, default).
332 Fixes for yaz_iconv routines: changed trie-based character set conversions
333 to use only non-negative values for bit fields due to Sun's C compiler not
334 supporting negative values.
336 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
337 sequences where not read correctly. Fix by Rustam Usmanov.
339 Updated win/makefile to use options, settings which makes things
340 compile with VS C 2005.
342 --- 2.1.12 2006/02/01
344 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
346 In ZOOM socket code, use select instead of poll on MacOSX.
348 ZOOM-C now support client-side compilation of CQL into RPN that is
349 sent to the server, enabling CQL to be used against all Z39.50
350 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
351 ZOOM_query object, and submit it using ZOOM_connection_search().
352 The CQL-to-RPN translation uses a configuration file, the name of
353 which must be specified in the Connection's "cqlfile" option.
355 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
356 function, which takes as its start-term parameter a ZOOM_query object
357 (which may have had either CQL or RPN set into it).
360 --- 2.1.10 2005/11/29
362 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
363 GFS to support this as well. Backend handler, bend_srw_update, does the
364 update work. Code contributed by Ko van der Sloot.
366 Allow retrieval of Search Result-1 information in ZOOM by the use of
367 options that are attached to a result set. ZOOM documentation updated
370 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
371 UTF-8 conversion. Patch by Raj Patel.
373 Added option -m to GFS to control formatting of timestamps in log file.
375 Added 'exit' as synonym for 'quit' in yaz-client
377 Added support for specifying SRW resultSetId + resultSetIdleTime in a
378 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
379 for the new members. Patch by Ko van der Sloot.
381 Added support for SRU POST. It is supported for content-type
382 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
384 Do not build the separate Multi-threaded (MT) library libyazthread.la.
385 Instead make the library libyaz.la multi-threaded. Threading as a whole
386 can still be disabled by configure option --disable-threads. Previosly,
387 with older GLIBCs there were problems with MT libs under Apache. This
388 has now been fixed a long time ago.
390 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
393 CQL module modified to be case insensitive for relations/indexes/operations.
395 Fixed bug in CQL transform code: incorrect value relationModifieder
398 Added 'show all' command for yaz-client which retrieves all results
401 Added new yaz-client, xmles, which takes a (private) OID and
402 a document to be sent as an extended service request.
404 Describe new yaz-client commands wait_response and set_auto_wait.
406 Increase TCP/IP listener backlog from 3 (which I am guessing was
407 copied from the SunOS manual entry way back when) so SOMAXCONN, so
408 that the socket will queue as many incoming connections as it's able
409 to handle ongoing connections. In other words, it will never now
410 refuse a connection that it would be able to handle merely because
411 it's not got around to accepting() enough of the pending connections
412 yet. This is the behaviour anyway under Linux, where the listen()
413 argument is ignored; but not under BSD and on systems such as
414 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
415 YAZ-based servers should now be uniform across operating systems in
418 yaz-marcdump uses 64-bit file access on some systems. This is enabled
419 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
420 This allows yaz-marcdump to read large MARC batches (>2 GB).
422 Modified all YAZ source files - except the source which is auto-generated
423 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
426 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
427 corresponding to the existing *_setl() function. These allow option
428 values containing arbitrary valuues.
430 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
431 ZOOM_resultset_sort() in new applications. Its behaviour is identical
432 except that it returns an indicator of whether or not the sort
433 criterion was accepted (0 for OK, -1 for invalid).
437 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
438 MARC output rather than returning "new" buffer.
440 yaz-client warns about unknown init options.
442 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
446 Added support for SRW sort in Generic Frontend Server. Patch
447 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
448 sortKeys - or NULL if none is provided.
450 Fixed bug #307: It was impossible to specify indefinite/no timeout
451 for ZOOM_event. Special timeout value -1 now means indefinite timeout
454 Added support for multiple languages and charsets to be specified in
455 ZOOM. Each charset/language is separated by a blank. If negotiation is
456 in effect in init-response, Option
457 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
458 Code based on patch by Vasiliy Osadchuk.
460 Fixed bug #306: infinite recursion that occurred when calling
461 yaz_log_level_init as the first call (before other log level or
464 Fixed bug in scan handling in front end server: if preferred-Position-In-
465 Response was non-present, a NULL pointer referece was performed.
469 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
470 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
471 now defined for all those error codes. So instead of putting 109 in
472 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
473 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
475 Modified the yaz-marcdump utility to skip garbage bytes between MARC
478 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
480 Program yaz-client now exits and produces an error message if multiple
481 Z39.50 servers are specified on the command line (none or one allowed
484 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
489 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
491 Fixed bug #272: Preserve spacing for CCL terms.
495 Added support for virtual hosts and multiple backend servers for
496 the YAZ frontend server. The configution is XML based and
497 support specificition of CQL to RPN mappings and explain information.
498 See section "Virtual Hosts" in the YAZ manual.
500 Extended OPAC display utility. OPAC display utility renders
501 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
502 to supplement yaz_marc_decode_wrbuf.
504 Fixed a bug in MARC decoder that could caused it to crash for some
505 invalid MARC records. More diagnostics and warnings where added in
506 XML output (warnings, etc are stored in comments).
508 --- 2.0.34 2005/02/08
510 Fixes for UNIX domain sockets. Bug #261.
512 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
514 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
515 Added yaz_marc_subfield_str which defines subfield lead string which is
516 used in YAZ_MARC_LINE format. Default string is blank+$. Added
517 yaz_marc_endline_str which defines end of fields string used in
518 YAZ_MARC_LINE format. Default string is newline.
520 Experimental support for MarcXChange. This format can be produced
521 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
522 http://www.bs.dk/standards/MarcXchange.xsd
524 Added yaz-client commands scansize that sets maximum number of
525 entries to be returned by scan.
527 --- 2.0.32 2005/01/11
529 Added support for SRW scan in yaz-client and Generic Frontend Server.
531 * Added whereInList member to SRW Scan Term.
533 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
535 Fixed NMEM system to return aligned blocks on the smallest boundaries
536 that are suitably aligned for all possible types on the particular
537 architecture YAZ is being built for.
539 --- 2.0.30 2005/01/04
541 Fixed numerious warnings that was issued with newer versions of GCC.
543 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
544 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
547 Make YAZ Generic Frontend Server slightly faster.
549 Enhance (and reduce) logging for Generic Frontend Server.
551 Revert YAZ log system so that it flushes every write operation
552 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
554 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
555 instead of LOG_, due to name clash with syslog(3). LOG_ are still
556 present. New applications should define YAZ_USE_NEW_LOG=1 - this
557 will effectively disable old definitions.
559 --- 2.0.28 2004/11/09
561 Added yaz_log_time_format which specifies log format using
564 Added yaz_log_module_level which returns mask for a module. Value
565 is non-zero mask a if module is enabled; zero if disabled.
567 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
568 in include/yaz/cql.h.
570 Fixed bug #176: Dont throw diagnostics on empty SRU args.
572 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
574 Fixed bug #172: RPM builds does not enable SSL.
576 Doxyfile.in part of dist. Doxyfile generated by configure.
578 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
579 are given and the corresponding component does not exist.
581 Extend CCL documentation in YAZ reference. Describe r=r.
583 --- 2.0.26 2004/10/01
585 Fixed MARC->MARCXML conversion to properly deal with
586 fields, subfields, indicators having non-ASCII characters.
588 Fixed MARC->MARCXML conversion so that ASCII control characters
589 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
592 Added YAZ GFS support for conversion from Z39.50 surrogate
593 diagnostics to SRW surrogate diagnostics.
595 Bug fix: YAZ GFS did not return schema in explainResponse.
597 --- 2.0.25 2004/09/30
599 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
600 now converts recordSchema to elementSetName as well as schema URI.
602 Fixed bug in COMSTACK that prevented HTTP request packages from being
605 --- 2.0.24 2004/09/29
607 Added CCL facility r=r "range" which is similar to r=o "ordered" but
608 does not require white-space before and after the dash in a range, e.g.
609 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
612 Fixed a few AC_TRY_LINK configure tests that did not operate properly
613 due to new GCC removing "redundant" code.
615 Added yaz-client commands scanpos and scanstep that sets preferred
616 position and step-size for scan.
618 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
620 Added CCL utility ccl_qual_buf which parses one or more CCL
621 spec lines in a buffer.
623 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
624 of name and value - ignoring empty lines and comments.
626 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
628 Added odr_get_element_path which returns current element path for an
629 ODR handle. This utility is useful in error handling or user-defined
632 Added ODR_PRINT utility odr_set_stream which is is a more generic
633 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
634 to a write function and pointer to close function. The close function - if
635 non-NULL - will be called during odr_destroy.
637 Fixed bug in CCL parser where truncation char was not removed from
638 right side when truncation=both was in effect.
640 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
643 --- 2.0.23 2004/08/11
645 Fix buffer overrun in CQL parser when dealing with proximity (%).
647 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
648 to UTF-8/UCS conversion is now only based on codetables.xml.
650 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
652 --- 2.0.22 2004/08/06
654 Add support for more "commit changes" in ZOOM (uses Extended Services).
656 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
659 Yet another small fix for configure of SSL.
661 --- 2.0.21 2004/05/14
663 Fix SSL libs for configure when --with-openssl=DIR is given.
665 --- 2.0.20 2004/05/10
667 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
669 SSL comstack now uses yaz.pem certificate file on server side
670 by default. Certificate filename can be configured by calling
671 comstack function cs_set_ssl_certificate_file before cs_bind is used.
673 Fix bug regarding multiple calls to ZOOM_connection_connect.
675 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
677 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
678 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
680 ZOOM now allows inspection of X509 peer certificate for verification.
681 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
683 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
684 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
685 as "modular" but it simplifies things.
687 Added cs_get_peer_certificate to that returns peer X509 PEM.
689 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
690 NULL if SSL is unavailable.
692 Documentation about MARC decoding tools.
694 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
696 --- 2.0.19 2004/03/30
698 Rename CHANGELOG to NEWS to follow GNU style packing.
700 Fix bug with missing initialization of member in init_diagnostics.
701 This bug affects threaded version of GFS server.
703 --- 2.0.18 2004/03/20
705 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
708 Ensure zlib.dll is packed with Windows install.
710 --- 2.0.17 2004/03/17
712 Fix encoding of xsd:string to use text instead of CDATA.
714 Fix endless loop in CQL parser with unbalanced ".
716 Use a more compact way to store MARC-8 conversion tables.
718 --- 2.0.16 2004/03/16 Debian only
720 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
723 Update CQL parser to use new CQL 1.1 modifiers for booleans and
728 --- 2.0.15 2004/03/01
730 Another fix for decoding of XML packed records.
732 --- 2.0.14 2004/02/25
734 Fixes for Chunked encoding. White space not ignored after length spec.
736 Update NS and use default NS for SRW diagnostic elements.
738 --- 2.0.13 2004/02/23
740 Implement ZOOM_resultset_cache_reset which resets record cache.
742 Implement ZOOM_resultset_sort which sorts a result set.
744 Implement chunked HTTP transfer.
746 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
748 --- 2.0.12 2004/02/16
750 Added member 'schema' to bend_explain_rr structure so that backend
751 can specify explain record identifier. Defaults to Zeerex 2.0.
753 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
755 --- 2.0.11 2004/02/16
757 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
760 Added init command for yaz-client which sends "extra" init request.
762 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
763 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
765 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
767 Make ZOOM error code for "invalid query".
769 Fixed compilation for SSL which wasn't properly enabled for all platforms.
771 --- 2.0.10 2004/02/05
773 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
776 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
778 Added option -p <file> to make Generic Frontend Server to write PID file.
780 Added option -D to put Generic Frontend Server in background on its own.
782 Make ZOOM C recognize option "password". If unset, "pass" is used
783 (for backwards compatibility).
785 Fixed a bug in Generic Frontend Server that could make it crash if a
786 client sets characterSetNegotation bit, but didn't pass negotiation stuff
789 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
790 Must be issued before open, in order to be in effect.
792 --- 2.0.9-6 2004/01/12 Debian/Windows
794 Make the SRU server more picky WRT unknown params, etc.
796 Bug fix: ZOOM scan response didn't return displayTerm - when present.
798 New YAZ client command, options, that sets Z39.50 options.
800 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
801 options from a string of tokens (one token for each option bit).
803 Update SRW diagnostic code messages.
805 --- 2.0.9-5 2004/01/07 Debian/Windows
807 Handle user defined stylesheet for SRW/SRU.
809 --- 2.0.9-4 2004/01/06 Debian/Windows
811 Fix bug in decoding of Content-Length.
813 --- 2.0.9-3 2004/01/06 Debian/Windows
815 Fix a bug with decoding of XML packed records.
817 --- 2.0.9-2 2004/01/05 Debian only
819 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
821 Fix bug in SRW/SRU diagnostics decoding.
825 Fixed bug in Generic Frontend Server which could drop records exceeding
826 preferred message size. Reported and fixed by Irina Dijour.
828 Fixed calculation of package size for structured records in Generic
829 Frontend Server. Reported and fixed by Irina Dijour.
831 Fixed namespace for SRW/SRU diagnostics.
833 Fixed SEGV in yaz-client that occured for HTTP connection errors.
837 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
838 this version is incompatible with version 1.0 and older YAZ SRW/SRU
841 CQL changes to reflect recent changes to the specification:
842 * Documentation talks about context sets instead of index sets.
843 * Documentation talks about indexes instead of qualifiers.
844 * The CQL-to-PQF transformer's configuration file now uses
845 "index.set.name = <attributes>" instead of the old form
846 "qualifier.set.name = <attributes>". (Both forms are still
847 understood but the latter is deprecated.)
848 * CQL terms with no explicit index specified are now interpreted as
849 cql.serverChoice instead of srw.serverChoice (which of course
850 behaves exactly the same.)
854 MARC conversion can now generate ISO2709 output in another
855 character set. yaz-marcdump uses this facility if you invoke it
858 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
859 functions from there can be used from C++.
863 Frontend server now transfers memory from decoded packages to stream
866 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
867 references to show up.
869 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
870 the ZOOM Abstract API. The older names for the same options are still
871 also supported for the benefit of old applications.
873 ZOOM-C supports "implementationId" and "implementationVersion" options
874 to go along with "implementationName". These allow the user code to
875 specify identification strings to be sent to servers.
876 Add OID for the new ExtLite attribute set.
878 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
879 as requested/supplid by Ere Maijala <ere@atp.fi>
881 For generic frontend server, reverse the order of
882 "toolkit-supplied / application-supplied" strings sent as implementationId,
883 Name and Version. Also, remove the spaces around the slash. This brings
884 the GFS in line with the behaviour of ZOOM-C on the client side.
886 Add function ZOOM_scanset_display_term.
888 yaz-client shows scan displayTerm if present.
890 Utility yaz-iconv is now installed by default along with the man page
893 Extend configure check for OpenSSL to use pkg-config where available (such
896 Incorporate patch by Morten Bogeskov which allows a Unix file socket
897 server to specify uid/gid/mask for socket using the format
898 unix:[user=uid,][group=gid,][umask=mask,]file=path
899 If file= is omitted the existing format is assumed, e.g.
901 in which case the mask is 0666 (rw for everybody).
903 Major restructure of YAZ source. All source in libyaz is in src directory.
904 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
905 util (utility programs such as ASN.1 compiler, yaz-marcdump).
907 Added man page for utility yaz-marcdump (used to be called marcdump).
908 yaz-marcdump is installed by 'make install'.
910 Fixed a memory leak in Generic Frontend Server that occurred when decoding
911 of incoming package failed.
913 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
915 Change prototype of odr_perror: add const to message string.
917 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
919 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
920 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
921 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
922 DNS lookup. There should not be any compatibility problems with this
923 assuming that blocking=1 or 0 is used.
925 Fix bad reference in UNIX comstack in function cs_addrstr.
927 Fix for compilation on AIX.
929 The generic front-end server (server/seshigh.c) now supports returning
930 Init diagnostics to the client in User-information-field, in
931 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
936 Allow any CQL relation (not just all,any,exact,scr).
938 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
939 that features the same UI.
941 Implemented command update0 in YAZ client which is equivalent to
942 update but uses old of Ext Update ASN.1.
944 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
945 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
946 Previously no OID was used for this info.
948 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
949 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
950 returns 'malformed search term' otherwise.
952 SortResponse member resultCount now set to NULL in sort handler of
955 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
958 Add three new utility functions for translating OIDs between various
959 formats -- symbolic name such as "Usmarc", minus-1-terminated int
960 arrays and dotted strings such as "1.2.840.10003.9.5.1":
961 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
962 char *oid_to_dotstring(const int *oid, char *oidbuf);
963 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
965 Reverted modifications for ES Update definition for z_IU0Update
966 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
967 is back to YAZ 2.0.2.
969 String value attributes for CCL parser.
971 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
972 which their FirstSearch server returns in Init responses, sometimes
973 carrying useful diagnostic information when Init fails. This has the
974 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
975 "z39.50/oclcui.asn", where its definition is somewhat different from
976 what OCLC document on their web-site, as required to interoperate with
979 Support for anonymous authentication in yaz-client. Use the command
982 * Fix the OID of the Index Data-local "admin" Extended Service from
983 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
984 the 1000, which indicates a locally-defined OID, was a mistake.
988 Fix CCL directive @case handling so that it affects string match for
989 both CCL keywords and qualifiers.
991 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
992 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
993 Decoder has been updated with ASN.1 changes as listed in
994 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
995 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
996 z_IUUpdate, remains unchanged.
998 ZOOM_record_get may now return a record in a specific character set.
999 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1000 "from" is the character set of record as returned by target. "to" is
1001 the character set to be returned. If omitted, "to" is UTF-8.
1003 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1005 New ODR utility, odr_getelement, which returns name of element for
1006 which encoding/decoding failed.
1008 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1009 in cases where a required element was omitted.
1011 Bug fix: some MARC8 sequences were not converted.
1013 New ZOOM option "step" which specifies number of records to be
1014 retrieved in one chunk. Used in conjunction with "start" and "count".
1016 SRW support for yaz-client. Use scheme http: to use it, e.g.
1019 yaz-client no longer does (un)intelligent character set conversions
1020 by default. Can be enabled with charset and marc_charset commands.
1022 xmalloc trace fix for 64-bit systems such as DEC alpha.
1024 Solaris 2.6 compile fix.
1026 New function, cql_strerror() translates SRW error codes, as returned
1027 by cql_transform_error(), into human-readable English strings. Used
1028 in yaz-client diagnostics when appropriate.
1030 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1031 converts it into a type-1 query which is sent to the server. This
1032 makes CQL available for use with all Z-servers, as opposed to the tiny
1033 minority that can handle CQL queries themselves.
1035 --- 2.0.2 2003/04/28
1037 New Debian package layout similar to the Redhat Package layout.
1039 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1040 and search result respectively.
1042 --- 2.0.1 2003/04/25
1044 Redhat package is now several packages: libyaz (runtime libraries),
1045 libyaz-devel (development and documentation, and yaz (utility programs).
1046 Package spec file by Morten Bøgeskov.
1048 New member 'schema' in struct bend_fetch_rr which the name of requested
1049 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1050 handler MAY set this to reflect the schema of the returned record.
1052 New member 'display_term' in struct scan_entry. GFS now sets member entries
1053 and allocates scan entries to be filled by user scan handler. In previous
1054 version, entries member was allocated by the scan handler. That still works,
1055 but the GFS will ignore member display_term - assuming it was NOT set by
1056 the handler. The fact that the GFS now allocates the entries both allows
1057 for new members and makes a scan handler easier to write.
1059 Fix CQL lex buffer overflow.
1061 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1062 SRU default recordPacking is string.
1064 SRU protocol support for frontend server.
1066 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1068 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1070 Added scan for the ZOOM shell (zoomsh).
1074 * String Identifers for Schemas (Amendment 5).
1075 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1076 Old definition for schema
1077 Odr_oid *schema; /* OPT */
1082 Z_InternationalString *uri;
1083 #define Z_Schema_oid 1
1084 #define Z_Schema_uri 2
1087 * resultCount parameter to Sort Response (Amendment 1).
1088 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1090 Support for SRW 1.0 over HTTP. This is an optional feature and
1091 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1094 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1095 on the same port. SRW SearchRetrieveRequests are mapped
1096 to bend_init,bend_search,bend_fetch,bend_close.
1098 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1100 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1101 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1103 ZOOM connections are SRW based if schem http is used for hostname
1104 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1105 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1107 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1108 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1109 distance=n, order=true/false, relation=le, prox unit=word. If
1110 n is omitted, distance 1 is used.
1112 Fixed problem with C compiler include path in wrong order.
1114 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1115 on Solaris. Patch from Ko van der Sloot.
1117 New MARC decode API. All new functions operate on a yaz_marc_t
1118 handle. The most important new functions are: yaz_marc_create,
1119 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1120 decode and destroy respectively. Decoder can produce formats
1121 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1122 include/yaz/marcdisp.h.
1124 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1125 to UTF-8, UCS-32, wchar_t or Latin-1.
1127 * Prototypes for yaz_iconv_-functions moved to separate header
1128 include/yaz/yaz-iconv.h.
1130 Make a few private functions 'static' in unix.c. This prevents
1131 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1133 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1134 are set when Init Response is received.
1136 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1137 but returns diagnostic set as well.
1139 New function yaz_strerror which is a portable wrapper for
1140 strerror/strerror_r/GetLastMessage.
1142 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1143 is returned for MARC. If type is "oai", then OAI MARC is returned.
1145 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1148 --- 1.9.2 2002/11/26
1150 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1152 Fix bad race conditions on SIGTERM and terminate gracefully in
1155 Move retrieval (data1) module to Zebra since nobody seems to be
1158 Add GRS-1 render for ZOOM using same format as yaz-client.
1160 --- 1.9.1 2002/10/05
1162 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1164 Fix broken ESpec handling in data1 module.
1166 SGML reader parses comments and makes them part of the data1 tree.
1168 Added several type casts so that YAZ compiles as C++ code.
1170 ZOOM didn't handle PDU encoding failures properly.
1172 Added more Bib-1 diagnostics (approved extensions).
1174 GNU configure: better check for iconv.
1176 More portable use of accept, getpeername. Check for socklen_t. Use
1177 int/size_t if socklen_t is not defined.
1181 PQF parser rejects bad queries - including those with extra
1182 characters in them. PQF parser used to silently ignore that.
1183 Cleaner API for PQF added, which allows you to get detailed
1184 error information for bad queries (see yaz/pquery.h).
1186 Fixed bug in ZOOM_record_get for type "database".
1188 Implemented mini iconv library supporting conversions between
1189 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1191 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1193 --- 1.8.9 2002/08/20
1195 Fixed ZOOM C record cache so that preferredRecordSyntax and
1196 elementSetName is used to check for already fetched records.
1198 --- 1.8.8 2002/08/02
1200 Added three members in bend_initrequest structure to facilitate
1201 character set negotiation.
1203 Fixed a bug in frontend server that could cause indefinite
1204 loops under rare conditions.
1206 Revised character set utilities (charneg.h) so that encoding
1207 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1209 For PQF, directive @term <type> sets term type for Scan/Search.
1210 Here <type> is general, string, numeric, null. The term type
1211 is inherited - just like @attr.
1213 New call odr_set_charset that sets character set conversion for
1214 international-strings on a ODR stream. Prototype is:
1215 int odr_set_charset(ODR o, const char *to, const char *from);
1216 The InternationalString is still represented as C string in YAZ
1217 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1218 won't). On the protocol level, you can use any encoding.
1220 Support for UNIX sockets in ZOOM.
1222 Solaris recv sometimes returns errno == ENOENT. It is treated as
1223 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1225 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1226 both client and server. Code by Morten Bøgeskov.
1228 --- 1.8.7 2002/05/22
1230 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1231 that they can be used directly from Visual Basic. You must recompile
1232 your windows APP if you're using ZOOM.
1234 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1235 Commands "lang" and "charset" sets language and character set respectively.
1236 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1237 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1239 Attributes from multiple CCL fields may be OR'ed rather than merged
1240 using directive "@field or". Fields are still merged by default -
1241 equivalent to "@field merge".
1243 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1246 Fixed bug in zget for parameter ExtendedServicesResponse.
1250 --- 1.8.6 2002/03/25
1252 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1254 Client displays USR.1:SearchResult-1 (hits per term).
1256 Additional Search Info for search in Generic Frontend Server.
1258 Fixed CCL parsing of "field=s".
1260 WIN32 installer - using the excellent NSIS software from nullsoft.
1262 Fixed CCL parsing of "field = - <number>".
1264 Added function yaz_marc_decode that decodes MARC for line mode
1265 display or XML (similar to that used by JZKit).
1267 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1268 Z39.50. But ISO/ILL was, however.
1270 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1271 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1276 --- 1.8.5 2002/02/03
1278 New YAZ client features: Command completion and new commands:
1279 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1280 Code provided by Jacob Poulsen.
1282 New call oid_trav, that visits all registered OIDs via callback.
1284 Function ZOOM_record_get now returns const char pointer rather than
1285 void pointer. It saves a lot of type casts.
1287 For YAZ client, command "auth" now allows you to set authentication
1288 in IdPass style. It is enabled when three tokens are given - order
1289 is user, group and password.
1291 Fix memory leaks in MARC record handling for ZOOM.
1293 New option for YAZ client, -k <kilobytes> that sets
1294 maximum record size. Similar to -k option for generic frontend
1295 server and yaz-ztest.
1297 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1299 Prefix query parser reports "fail" when bad attribute set is given.
1301 Fix in MARC decoder. Proximity logging. Fix for attribute set
1302 in scan handler for server. Patches by Shigeru Ishida.
1304 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1307 Configure option --with-openssl=<dir> now works when a directory is
1308 specified. Patch provided by Morten Bøgeskov.
1310 New option for YAZ client, -u <auth>, that sets authentication.
1312 ZOOM fix: error information was sometimes "missing", since error
1313 was cleared/reset too when it shouldn't.
1315 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1317 --- 1.8.4 2002/01/04
1319 Scan for ZOOM API. New object ZOOM_scanset. New functions
1320 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1321 ZOOM_scanset_destroy.
1323 New ZOOM function, ZOOM_connection_last_event, that returns type
1324 of last event (such as "receive data", "send data", "apdu received",
1327 New ZOOM option, schema, that specifies schema for retrieval.
1329 New CCL feature. Qualifiers can be aliases for one or more
1330 other qualifiers (if more than one is given, OR is used).
1332 ZOOM uses named result sets if target supports it.
1334 Two new YAZ client commands: . (dot, which sources a script of YAZ
1335 client commands), and ! (to execute shell command.). Implemented
1338 Working on Debian packages.
1340 --- 1.8.3 2001/11/19
1342 YAZ client enables named result sets only if target supports it.
1344 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1346 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1347 with key="host" to get same result.
1349 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1350 Function Z3950_resultset_record(s) returns references to records
1351 "owned" by resultset. To become owner use Z3950_record_clone.
1353 Function z_ext_record handles Extended Services. Thanks to
1356 --- 1.8.2 2001/11/12
1358 CCL Parser fix: ignore token comma when dealing with and-lists.
1360 Documentation updates for COMSTACK.
1362 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1363 Changed prototype Z3950_records. For some functions, int parameters
1364 were changed to size_t.
1366 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1369 New MARC decode/display function, marc_display_exl, which properly rejects
1370 non-ISO2709 records. YAZ client uses it.
1372 --- 1.8.1 2001/10/29
1374 Fix bug: local attribute set wasn't set correctly in PQF strings.
1378 * Old Z39.50 codecs no longer supported.
1380 Added ZOOM C binding. See http://zoom.z3950.org/
1382 Renamed states for COMSTACKs to avoid confusion with events.
1384 Implemented cs_look and proper cs_rcvconnect.
1386 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1388 Configure detects POSIX threads on OpenBSD.
1390 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1391 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1393 When error is returned from present handler, non-surrogate diagnostic
1394 is returned in present response (and fetch handler is no longer called).
1396 * Minor adjustments to pquery parser (PQF). Token characters may be
1397 escaped by using backslash (C-style).
1399 PQF parser allows string attribute values to be specified. For @attr,
1400 non-numeric characters after the equal-sign are treated as strings
1401 (e.g. @attr 9=title).
1403 CCL trunction character may be defined (@truncation in file)
1405 * function zget_ExtendedServicesRequest sets waitAction to
1406 waitIfPossible (was wait).
1408 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1411 CCL operator names may be set in field definition files (CCL_bibset).
1412 See ccl/bib1 for an example.
1414 Fixes in ASN.1 compiler for C++ compatibility.
1416 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1417 and "op_or" to avoid conflict with C++.
1419 Fixed problem with GNU readline detection on Redhat 7.0.
1421 Added step-size for Scan backend handler.
1423 Fixed bug that made the frontend server crash when no attribute
1424 set was specified for scan.
1426 Front-end server automatically switches to original working directory
1427 when installed as an NT service. Previously -w had to be specified to
1430 Added extended attributes for retrieval module (data1), so that data1
1431 records carry d1_readXML/SGML attributes. d1_read also supports
1432 null-data rules ( <tag/>)
1434 On UNIX when POSIX threads are available, a separate library libyazthread
1435 is created. Programmers should link with that library and the yaz library
1436 when using threads. The reason for the split was that some applications
1437 on Linux, such as Apache, doesn't work well when using shared objects that
1440 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1441 (or any frontend server) in SSL mode by specifying ssl: followed by
1442 address. Only tested on UNIX.
1444 Added feature for CCL module. Virtual structure s=al or s=ol generates
1445 and-list and or-list respectively instead of phrase search.
1449 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1450 log_mask_str. This was done to avoid name conflicts with other libraries
1451 (such as other PHP extensions).
1453 Added raw OID member for preferred record syntax (request_format_raw)
1454 and returned record syntax (output_format_raw) for backend fetch method.
1456 Config file yaz-config now accepts options so that it returns specific
1457 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1459 Shared library support for UNIX using GNU libtool.
1461 * Modified backend interface. Request/Response struct's replaced by
1462 one read/write C struct. For example bend_fetchrequest and
1463 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1464 Every handler - even search has to be registered in bend_init
1465 handler. This means that the YAZ library no longer refers to
1466 external functions and it makes it possible to make the whole
1467 thing a single DLL/SO.
1469 Added Segment handler for backend server.
1471 Added Zmbol/Zebra administrative functions to YAZ client.
1473 Threaded frontend server on UNIX (when POSIX Threads are available).
1474 Starting the server with option -T enables multi-threading.
1478 Added configure option --enable-comp/disable-comp to control use
1479 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1480 located in sub directory asn.
1482 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1483 in ${exec_prefix}/bin along with the other programs yaz-client and
1486 GNU automake used to maintain makefiles.
1488 Added several OID's.
1490 Changed retrieval module so that we can load records with no abstract
1491 syntax defined. Tagpaths in these records are fully composed of string
1494 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1498 On UNIX, the generated makefile now supports a proper 'make install'.
1499 The prefix can be set via GNU configure to set the install location
1500 (default is /usr/local).
1502 * YAZ programs client and ztest were renamed to yaz-client and
1503 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1504 locations, such as /usr/bin,/usr/local/bin,etc.
1506 * YAZ Header files were moved from include to include/yaz. YAZ Header
1507 files are referred to as include <yaz/log.h> rather than <log.h>.
1508 The YAZ include path (-I ..) is therefore the same as before. Programmers
1509 should update their #include statements or use -Ipath/include/yaz
1510 instead. The main motivation for doing this change is that YAZ header files
1511 can be installed in "standard" locations /usr/include,/usr/local/include
1512 without introducing conflicts, since ALL YAZ header files are stored
1513 in subdirectory yaz (under /usr/include for example).
1515 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1516 rather than project/workspace files. We switched because project files
1517 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1520 Changed name of logging function, logf, to yaz_log, to prevent name
1521 clash with some math-log functions. The YAZ header log.h defines logf
1522 to yaz_log (#define) so there should be no incompatibilities by this
1525 Added bend_start/bend_stop handlers for server. These handler are
1526 called on start/stop of server. For windows they are called whenever
1527 a service is started/stopped.
1529 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1530 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1531 in util/yc.tcl. The auto-generated C code structures are, in a few
1532 cases, incompatible with the old decoders. There are differences in the
1533 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1534 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1535 The preprocessor variable ASN_COMPILED is defined when the compiled
1536 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1537 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1538 wish to use the old encoders/decoders you can specify --disable-yc
1541 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1542 version so that it supports both new - and old version of DB Update
1544 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1545 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1546 change. The name parameter can be set to 0 in which no name is specified
1547 for the construction. The macros odr_implicit and odr_explicit sets name
1548 parameter to zero for the construction involved. New macros
1549 odr_implicit_tag and odr_explicit_tag are similar to the others,
1550 except that a name parameter is added. For programmers' that don't use
1551 ODR they probably only need to change the call to z_APDU and z_External.
1553 Added access control facility by interfacing the TCP wrapper library.
1554 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1555 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1556 name of the daemon and enables the access control as specified in
1557 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1559 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1560 den Dool <H.M.vdnDool@kub.nl>.
1562 Added reference ID parameter to most functions in server API - refer
1563 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1565 Changed name of ccl library to libccl.a (was ccl.a).
1567 Fixed bug in decoder for Explain (Category TargetInfo).
1569 Added support for GNU readline in client. Thanks to Jacob Poulsen
1570 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1572 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1573 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1574 IMPLEMENTATION! This change was made to the development version before
1575 the ZIG decided to retract the amendment. If any users MUST be
1576 compatible with the original Update definition, PLEASE CONTACT US, and
1577 we will include a separate definition corresponding to the old Update
1578 ES. Note that because of the change to the ASN.1 of the
1579 TaskPackageRecordStructure we cannot define a single structure that
1580 will support both versions.
1582 * Added const modifier to buffer parameter for some ODR/BER encoding
1583 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1584 completeWAIS, odr_dumpBER.
1586 Fixed bug in client.c which caused a crash when a scanResponse didn't
1587 contain positionOfTerm.
1589 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1590 * will cause an error in a client if a non-YAZ target sends both a
1591 * list of Scan entries and non-surrogate diagnostics.
1593 Retrieval module enhancements. Tag sets may be typed in the reference
1594 to it. From the .abs-file the "tagset" directive takes a third optional
1595 integer type for the tag set referenced. From a .tag-file the "include"
1596 directive takes a third optional type as well. The old "type" directive
1597 in the tag set itself is still recognized but acts as the default type
1600 Backend interface change. Individual Scan terms returned from bend_scan
1601 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1602 in include/backend.h.
1604 Retrieval module enhancements. Multiple tag sets and attribute sets may
1605 be specified in abstract syntax specs. Revised the error/warning for
1606 logging messages reported by the retrieval module when reading the
1609 Object Identifier system (oid_..) changed. The API is backwards
1610 compatible but the oid-routines now allocates new OID's when needed.
1611 Raw OID's may be specified in oid_getvalbyname.
1613 YAZ now uses GNU configure to generate Makefile(s).
1615 * Minor changes in some of the member names of DeleteResultSetRequest and
1616 DeleteResultSetResponse. See include/proto.h.
1618 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1619 and added member 'languages' in TargetInfo (which was missing).
1621 Changed the way attribute sets are handled in the retrieval
1622 module. These are now cached, just like the abstract syntaxes
1625 Changed YAZ so that it links with compiled ASN.1.
1627 Added Explain-schema definitions and mapping routines. The following
1628 Explain categories have been implemented: AttributeDetails,
1629 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1631 Fixed minor bug in Windows version of Server Library.
1633 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1635 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1637 Added EXTERNAL: UNIverse Resource Report (non-standard).
1639 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1640 ENUMERATED and SET OF.
1642 * Added 'const' to some of the char pointer arguments for the
1643 functions, data1_read_node, data1_getelementbytagname,
1644 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1647 Fixed bug in data1_insert_taggeddata - the last_child member of
1648 parent wasn't initialised.
1650 * Changed data1_read_record and data1_read_node so that the supplied
1651 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1652 doesn't refer to any parts of the "SGML"-buffer.
1654 Fixed bug in server library (Windows version of statserv_remove).
1656 * Changed code so that it compiles as C++. The type definition
1657 of Odr_fun which is a member of Odr_arm was changed. The result is,
1658 that an explicit typecast is needed for the fun pointer when
1659 using Odr_arm - as in:
1660 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1662 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1664 Implemented the new structured date and time definition as approved
1665 by the ZIG. Added schemaId element to the specificTag in Espec-1
1666 (also approved at the last ZIG). Thanks to RVDM.
1668 Added some Object identifiers (RVDM).
1670 Changed the Update Extended Service (RVDM).
1672 Added command "refid" to client which specifies referenceId for
1673 the following requests.
1675 Implemented extended service handling for server. See ztest.c
1676 for an example as well as backend.h. New handlers are registerd
1677 in the Init handler.
1679 * Changed interface for sort in server.
1681 Added new members to statserv_options_block. It allows a server
1682 to read options from another source than just the command line. Thanks
1683 to Charles Woodfield.
1685 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1686 renamed to zboolean. Some C++ compilers complained about the name.
1688 Minor changes to gils.abs. Added index 's' (sort) on title
1689 and date/time-last-modified.
1691 --- 1.4pl2 1998/1/30
1693 Fixed bug in server library regarding inetd mode (-i). This bug
1694 was introduced by release 1.4.
1696 --- 1.4pl1 1998/1/29
1698 Added sort facility in client and backend server interface.
1700 Fixed problem with dependencies in Makefile(s).
1702 Fixed bugs for encoders/decoders of extended services and
1705 Implemented sub-tree feature for schemas. Sub-trees are
1706 referenced in *.abs-files. See explain.abs for an example
1707 of the use of this feature.
1709 Modified bib1.att; local attributes for ANY didn't include
1710 ANY itself (only affects use of the retrieval module).
1712 Fixed bug in plain SGML reader in function data1_read_node:
1713 tags with prefix "var" was incorrectly interpreted as variants.
1715 Added feature "sub-schemas" to enable references to - and definitions
1716 of - group of elements.
1718 * Removed member parent from type data1_element (in data1.h).
1720 Implemented function odr_nullval() that returns the value of
1723 * Removed member num_children from data1_node (in data1.h).
1725 Made NT service interface part of the server library. The
1726 function statserv_main uses the NT service when required and
1727 calls the statserv_start / statserv_close routines.
1729 Routine zget_SearchRequest and zget_PresentRequest fills
1730 resultSetName/Id member with "default" instead of "Default".
1732 Fixed memory leak in server. Request queue member wasn't freed.
1734 Fixed nmem_exit so that memory is freed.
1738 Revised the CCL parser utility to be thread safe.
1740 Added function, oid_ent_to_oid, to replace the function
1741 oid_getoidbyent, which is not thread safe.
1743 * Added nmem_init and nmem_exit to initialize and release
1744 NMEM resources. Function nmem_init should be called once in the
1745 initial thread before NMEM/ODR is used. statserv.c and client.c
1746 have been changed accordingly. The change was necessary to make
1747 NMEM thread safe. The NMEM memory pool is shared amongst threads
1748 in a process. Unix-based applications will still work fine without
1751 Added NT Services interface for the the Z39.50 (statserv) Server.
1752 Refer to the ztest.c source on the usage.
1754 Windows 95/NT port using MSVC5.0. Project files are included in the
1757 * Defined new 'global' handle for the retrieval (data1) system. The
1758 new handled, data1_handle, describes the state of the data1 system.
1759 This handle is passed as first argument to virtually all
1760 data1 related routines. The functions data1_create and data1_destroy
1761 creates and destroys a data1 handle respectively.
1763 Added ODR encode stream member to all backend request structures
1764 init, search, scan etc. This stream should be used to allocate all
1765 memory used for the response when thread safe operation is needed.
1767 Changed the comstack utility, cs_addstr, to be thread safe. The
1768 returned hostname string returned by the function is now part the
1771 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1772 function. The cs_straddr takes a COMSTACK handle as argument, so this
1773 function must be used after cs_create and before bind/connect.
1774 This function is thread safe.
1776 Moved test server to 'ztest' directory - generic server code still
1777 in 'server' directory.
1779 Made prefix query (pquery.c) utility thread safe.
1781 Added new function modifier YAZ_EXPORT to 'export' public DLL
1782 functions when using windows (see include/yconfig.h).
1784 Added definitions to the OID database (util/oid.c) (RVDM).
1786 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1788 Added call to ccl_rpn_delete in client program.
1790 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1791 release of RPN structure.
1793 Added support for C++, headers uses extern "C" for public definitions.
1794 With input from RVDM.
1796 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1797 Thanks to Ronald van der Meer (RVDM).
1799 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1801 Added support for private extensions to the OID database
1802 (oid_setprivateoids()). Thanks to RVDM.
1804 Added optional, physical ANY (key replication)
1806 Fixed null-reference problem in GRS-1 output filter.
1808 Proximity operator added to Prefix Query Format (PQF).
1810 In test client command "base" accepts multiple databases.
1812 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1816 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1818 Smallish bug-fixes in the new encoders/decoders (explain).
1820 Bug fixed in DeleteRequest.
1822 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1824 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1826 Added SOIF syntax (using private OID for now) to retrieval module and client.
1828 Added Update extended service.
1830 Added SearchResult-1 additional info structure.
1832 Added optional CCL (ISO8777) interpreter as separate module. Available
1835 --- 1.2 1996/6/10 (1st anniversary release)
1837 Added Summary record syntax. Lightly tested.
1839 Added OPAC record syntax. Untested.
1841 Added ResourceReport service encoders/decoders. Untested.
1843 Fixed bug in z_Unit - wrong tagging on unitSystem.
1845 Fixed bug in the DiagRecs decoder.
1847 Added options for max PDU size and session timeout to frontend-server.
1849 Added documentation of query-language parsers and other supporting utilities.
1851 [frontend-server] Added Attribute set to the bend_scanrequest API.
1853 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1854 surrogate diagnostics were generated.
1856 [retrieval] Allow multiple local values for attribute.
1858 [retrieval] Allow multiple attributes per element in .abs files. index type.
1860 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1862 --- 1.1pl2 1996/4/10
1864 Minor changes, mostly specific to Zebra's requirements (retrieval)
1868 Repaired bug in frontend server when running multiple listening
1869 endpoints in dynamic mode.
1871 z_External() now won't break if a known, ASN.1 value comes encapsulated
1872 in an octet-string. The value will pass through unmodified in an Odr_oct.
1874 Added a bit of code to the demo client to decode & display
1875 ASN.1-structured records represented in the octet-aligned branch of
1876 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1878 Added z_ext_getentbyref() to the ASN module. Doc updated.
1880 * Completed the SCAN definition in the ASN module. This may break SCAN
1881 code based on older YAZ-versions at compile-time. The fix is easy -
1884 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1885 under the SCAN definition. Remember to initialize this, server-people.
1887 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1888 that this does not extend to ODR and ASN.
1890 Comstack allows insertion of established socket (primarily for
1891 inetd-operation of servers). Doc updated.
1893 Front-end server can now start from the inetd in TCP mode. Doc
1896 --- 1.0pl4 1996/1/24
1900 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1901 the rank and record number.
1903 Adjustments to the frontend server.
1905 Fixed diagnostic BER dumper. It ignored the file argument.
1909 Various changes to retrieval module.
1911 Changed the union discriminators of the protocol files from enums to
1912 ints paired with #defines.
1914 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1917 *Changed operator in the RPN structure to 'roperator', again to avoid a
1920 Fixed problems in Explain decoders/encoders.
1922 --- 1.0pl2 1995/12/6
1924 Memory bug in log module fixed.
1926 --- 1.0pl1 1995/12/5
1928 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1930 Bug in Explain DatabaseInfo module fixed.
1932 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1936 The shift to v1.0 signals that we now consider the *core* functionality
1937 of YAZ reasonably stable (the core being more or less equivalent to
1938 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1939 tested (Explain not at all - though that will happen soonish).
1941 Minor changes to code to support Windows port.
1943 Various minor changes after we're getting to use GRS-1 & co. more.
1945 Added Espec-1 format.
1947 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1948 of the protocol and it cannot be selected when encoding (maps into 'string'
1949 when decoding). Needed to talk to some servers.
1951 Demo client can request simple element set names.
1953 Added Diagnostic Format encoders/decoders.
1955 Added simple Close handling to frontend server (no hooks for resource
1956 reporting yet), and demonstration client.
1958 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1960 --- 1.0b3 1995/08/24
1962 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1963 handled incorrectly when records were requested in the searchResponse. This
1964 will only affect you if you use the frontend-server.
1966 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1967 Test-client will ask for and print GRS1. Ztest will return dummy records
1970 Added Explain encoders/decoders to the service-level API. Untested.
1972 Added Extended Services: Item Order encoders and decoders to the Service-
1973 level API. Untested. We could use a recent copy of the pertinent bits
1974 of the ILL protocol to add those bits.
1976 Added diagnostic format 1 encoders/decoders to the service-level API.
1979 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1980 odr_cons.c, which causes a more correct output.
1982 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1983 was always set to 0 when no records were requested in the searchRequest.
1985 * Added better external-handling. This shouldn't harm old code that
1986 *encodes* externals. It can break code that looks for a
1987 'single-ASN1-type' representation, since those types that are known
1988 are now decoded immediately. Look at the SUTRS sample code in
1989 seshigh.c and client.c. Documentation updated.
1991 Handling of structured records in bend_fetchresponse. Length -1 marks
1992 structured record, type is deduced from format field.
1994 --- 1.0b2 1995/06/27
1995 Fairly quick maintenance release to add SUTRS support.
1997 Fixed handling of SUTRS records in the demonstration client.
1999 * Added format field to the bend_fetchrequest and bend_fetchresponce
2000 structures of the backend API (frontend server). When the record is
2001 returned, the value of the format field is mapped to an OID. The
2002 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2003 of the record. The special value VAL_NONE in the bend_request means
2004 that no specific format was requested by the client. Documentation
2005 updated accordingly. Test server (ztest) will return a fixed dummy
2006 SUTRS record if your client requests SUTRS.
2008 Documentation updated accordingly.
2010 You can now set external libraries and RANLIB support in the top-level
2014 First public release.
