1 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2 that is treated as an ItemOrder with itemRequest being an XML document
3 external. The value of "doc" is the content.
5 Extended the GFS search facility. New member of bend_search_rr
6 'estimated_hit_count' signals that hits is known to be an estmate
7 (higher or lower than real hit count). New member 'partial_resultset'
8 signals that the search was partial (hit count is lower or equal than
9 real hit count). For Z39.50, the information is stored in resultSetStatus
10 member of SearchResponse APDU. For SRU, the information is signalled
11 via SRU diagnostic 59: "Result set created with valid partial results
16 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
18 Added ZOOM_connection_peek_event.
20 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
21 the following new functions:
22 ZOOM_event_nonblock, ZOOM_connection_process,
23 ZOOM_connection_get_{socket,mask,timeout},
24 ZOOM_connection_fire_event_{timeout,socket}.
25 The existing blocking event handler, ZOOM_event, is a wrapper for the
26 + blocking ZOOM_event_sys_{poll,select}.
28 Implemented function ccl_xml_config which parses XML version of CCL
29 configuration (bug #798).
31 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
33 Added timings utility (yaz/timing.h)
37 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
40 Fixed bug #779: Rotation of apdu.log fails.
42 Fixed for character set conversions:
43 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
44 Honor G1 set in MARC-8 decoding.
48 Fixed bug #775: char conversion does not handle Alternative UTF-8
51 Implemented function yaz_marc_read_line which parses MARC line format
52 records. There is a wealth of formats out there. So far, this function
53 reads line records produced by yaz_marc_write_line.
55 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
56 more generic and easier to remember(!) options: -i format and -o format
57 which specifies input format and output format respectively - where
58 format is one of "marc", "marcxml", "line", "marcxchange".
60 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
61 does not print anything except warnings for records.
63 For yaz-marcdump, added support for MARC split into files (-s) with a given
66 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
67 spec, at http://www.loc.gov/standards/sru/record-update/
68 This has changed the binary layout of the following structs:
69 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
70 bend_update_rr . Patch by Ko van der Sloot.
72 Added GFS utility function bend_assoc_is_alive which returns 1 if
73 association is still alive (client is connected); 0 otherwise (client
74 closed connection). This allows busy servers to stop working for
77 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
78 been a separate piece of software. This version of ziffy has been modified
79 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
81 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
83 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
84 Client code may now interrogate options such as "init_opt_sort" to
85 find out whether the server claims to support various options.
89 Added utilities yaz_{set,get}_esn to set/get element set name from
92 Removed the build of libyazthread.la. The libyaz.so is the threaded version
93 of YAZ and has been so since YAZ 2.1.10.
95 Implemented ZOOM_record_error which returns error information for
96 record (surrogate diagnostic).
100 Updates for SRU Update by Ko van der Sloot:
101 1. Changed name from "operation" to "action"
102 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
103 versions in the code, marked as 'backward compatible'.
104 3. Added diagnostics for SRU Update.
106 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
108 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
110 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
112 For GFS, fixed problem with SRU diagnostic 'First record position out of
113 range' being issued for 0 hits.
115 zoomtst10 part of Windows Build.
117 --- 2.1.36 2006/10/13
119 Implemented yaz_filepath_comp which splits a path into file path
120 components (required by Zebra 2.0.3+).
122 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
123 BSD inspired license until now so this should not have any real impact on
124 anybody. See http://www.opensource.org/licenses/bsd-license.php
126 Fixed bug #687: Missing log lines.
128 Fixed bug #678: CQL to PQF translation does not preserve double-quote
131 Fixed bug #689: SRU diagnostics to be added.
133 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
134 whether a connection is idle (no more work do do).
136 --- 2.1.34 2006/10/04
138 Change type of optval from long to int for invocation of setsockopt with
139 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
141 Added support for specifying the max log file size for the Generic
142 Frontend Server. The size is given with option -r.
144 --- 2.1.32 2006/09/21
146 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
148 --- 2.1.30 2006/09/17
150 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
153 Fixed bug in Generic Frontend Server that could cause a server to stop
154 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
156 For the generic frontend server, the maximum record size is used as maximum
157 size of incoming packages (SRU + Z39.50). The value until was previously
158 only used in Z39.50 Init negotiation and, later, in a session controlled
159 sizes of records returned. This is controlled using -k option. It can be
160 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
162 --- 2.1.28 2006/09/04
164 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
167 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
169 New option for yaz-marcdump -lpos=value which allows setting a portion
170 of MARC header to a certain value.
172 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
174 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
175 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
177 --- 2.1.26 2006/08/15
179 Fixed problem with SRU mode type (soap, get, post) for yaz-client
182 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
184 --- 2.1.24 2006/08/08
186 Fixed MARC ISO2709 encoding routines to deal with character set
189 Minor changes to GFS logging. Database included in search request log
192 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
193 cached/multiple records.
195 Shared libraries are built by default on Unix+configure.
197 Changed cql2pqf transformation to use a different evaluation order. The
198 new order is: always, relation, structure, position, truncation, index
199 and relationModifier. Old order was: always, relation, relationModifier,
200 structure, index, position, truncation. Note that the the latter ones
201 override former ones for identical attributes.. The new scheme means that
202 it is possible to override any existing attribute with a relationModifier.
203 And also that it is possible to override everything for the index rule
204 (except the ones listed in relationModifier). No order is perfect but this
205 one, we believe, covers more real cases.. The "always" should have been
206 called "default", since the attributes there can be overridden with all
209 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
210 compilation phase, but also for yaz-config --cflags output. This allows
211 us to have public headers with Libxml2 stuff in them . It should also,
212 eventually, make Libxml2 checks redundant in packages using YAZ, such
215 --- 2.1.22 2006/06/15
217 Changed SRU update structure bend_update_rr so that SRU diagnostics are
218 stored in uri, message and details.. Previously diagnostics were stored
219 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
220 compatibility.. but he's probably the only one affected, so.
222 Added support for CCL, compiled on the client side, in ZOOM-C. This
223 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
224 input; the resulting query objects can be used for for searching with
225 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
227 YAZ' configure searches for OpenSSL by default.
229 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
230 SL_CTX_use_certificate_file. See
231 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
232 for more info. Thanks to Ko van der Sloot.
234 --- 2.1.20 2006/06/02
236 Bug #600: SRU GET, POST support for yaz-client. Introduced
237 command 'sru' which selects method SOAP/GET/POST.
239 Allow missingValueAction to be specified for the sortspec string -
240 function yaz_sort_spec. By default, the missing value action is null.
241 Use ! to specify "abort". Use = followed by stringvalue to specify default
244 Ensured that Present-handler (if defined) is called in GFS before any call to
245 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
246 searchRetrieve requests.
248 Documentation for YAZ is now based on the Docbook XML/XSLT using
249 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
250 is no longer depending on jade/openjade or docbook-to-man scripts.
251 PDF is no longer part of the distribution - but can optionally be
252 made using DSSSL/jadetex or FOP.
254 Added retrieval handling support in Generic Frontend Server to support
255 conversion between MARC/XML as well as XSLTtransforms. See
256 etc/yazgfs.xml for an example.
258 Added Authentication support to Generic Frontend Server in SRU
259 mode. Authentication using HTTP Basic is supported, as is the use
260 of 'x-username' and 'x-password' parameters in the request itself.
262 Added support for a new character set MARC8s identical to MARC8 except
263 that it converts combined characters to single Unicode characters in the
264 Latin-1 range (when possible).
266 --- 2.1.18 2006/04/24
268 ASN.1 compiler 0.4: generates brief Doxygen file header for
269 generated .h/.c files.
271 Utility yaz_iconv now supports conversion to MARC-8.
273 New facilities for the MARC module. The reading - and writing of
274 content are separate methods for the yaz_marc_t handle. The following
275 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
276 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
277 format). Write functions have prefix yaz_marc_write_.. The existing
278 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
279 available. Removed support for OAI-MARC and simplexml (not the
280 simplexml from PHP5).
282 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
283 to be returned for this connection.
285 --- 2.1.16 2006/03/31
287 Allow multiple languages and charsets to be specified with
288 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
289 negcharset iso-8859-1,utf-8
291 Translation of proximity nodes from CQL into PQF now works.
293 Moved to automake 1.8, 1.9.
295 Added function yaz_log_set_handler which allows a log handler to be
296 installed. This handler will be called for all log messages. Output
297 to file is also produced; but that can be disabled by passing NULL
298 fname to yaz_log_init_file.
300 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
302 For SRW (including GFS), accept application/soap+xml as content-type
305 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
306 produces NO stylesheet reference even if a default stylesheet is specified
309 --- 2.1.14 2006/03/14
311 Updated Windows package to include yazd.dll + yazd.lib for the
312 Development component.
314 If the environment variable YAZ_LOG is set, then it is used as a
315 string indicating the default level of logging to use if not
316 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
317 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
318 used as before. So, for example, to omit warnings from YAZ logging,
321 cql_transform() now map structure and other attributes before indexes,
322 so that index-specific structures and other attributes can override
323 defaults. So now a combination of mapping specifications such as:
325 index.dc.date = 1=date-modified 4=5
326 does the right thing.
328 cql_transform() now also respects the "always" mapping specification,
329 which establishes an initial set of attributes to be used for all
330 terms except where overridden by more specific attributes associated
331 with the index, relation or modifier.
333 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
334 which mode to use; one of "post", "get" or "soap" (SRW, default).
336 Fixes for yaz_iconv routines: changed trie-based character set conversions
337 to use only non-negative values for bit fields due to Sun's C compiler not
338 supporting negative values.
340 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
341 sequences where not read correctly. Fix by Rustam Usmanov.
343 Updated win/makefile to use options, settings which makes things
344 compile with VS C 2005.
346 --- 2.1.12 2006/02/01
348 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
350 In ZOOM socket code, use select instead of poll on MacOSX.
352 ZOOM-C now support client-side compilation of CQL into RPN that is
353 sent to the server, enabling CQL to be used against all Z39.50
354 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
355 ZOOM_query object, and submit it using ZOOM_connection_search().
356 The CQL-to-RPN translation uses a configuration file, the name of
357 which must be specified in the Connection's "cqlfile" option.
359 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
360 function, which takes as its start-term parameter a ZOOM_query object
361 (which may have had either CQL or RPN set into it).
364 --- 2.1.10 2005/11/29
366 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
367 GFS to support this as well. Backend handler, bend_srw_update, does the
368 update work. Code contributed by Ko van der Sloot.
370 Allow retrieval of Search Result-1 information in ZOOM by the use of
371 options that are attached to a result set. ZOOM documentation updated
374 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
375 UTF-8 conversion. Patch by Raj Patel.
377 Added option -m to GFS to control formatting of timestamps in log file.
379 Added 'exit' as synonym for 'quit' in yaz-client
381 Added support for specifying SRW resultSetId + resultSetIdleTime in a
382 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
383 for the new members. Patch by Ko van der Sloot.
385 Added support for SRU POST. It is supported for content-type
386 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
388 Do not build the separate Multi-threaded (MT) library libyazthread.la.
389 Instead make the library libyaz.la multi-threaded. Threading as a whole
390 can still be disabled by configure option --disable-threads. Previosly,
391 with older GLIBCs there were problems with MT libs under Apache. This
392 has now been fixed a long time ago.
394 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
397 CQL module modified to be case insensitive for relations/indexes/operations.
399 Fixed bug in CQL transform code: incorrect value relationModifieder
402 Added 'show all' command for yaz-client which retrieves all results
405 Added new yaz-client, xmles, which takes a (private) OID and
406 a document to be sent as an extended service request.
408 Describe new yaz-client commands wait_response and set_auto_wait.
410 Increase TCP/IP listener backlog from 3 (which I am guessing was
411 copied from the SunOS manual entry way back when) so SOMAXCONN, so
412 that the socket will queue as many incoming connections as it's able
413 to handle ongoing connections. In other words, it will never now
414 refuse a connection that it would be able to handle merely because
415 it's not got around to accepting() enough of the pending connections
416 yet. This is the behaviour anyway under Linux, where the listen()
417 argument is ignored; but not under BSD and on systems such as
418 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
419 YAZ-based servers should now be uniform across operating systems in
422 yaz-marcdump uses 64-bit file access on some systems. This is enabled
423 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
424 This allows yaz-marcdump to read large MARC batches (>2 GB).
426 Modified all YAZ source files - except the source which is auto-generated
427 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
430 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
431 corresponding to the existing *_setl() function. These allow option
432 values containing arbitrary valuues.
434 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
435 ZOOM_resultset_sort() in new applications. Its behaviour is identical
436 except that it returns an indicator of whether or not the sort
437 criterion was accepted (0 for OK, -1 for invalid).
441 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
442 MARC output rather than returning "new" buffer.
444 yaz-client warns about unknown init options.
446 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
450 Added support for SRW sort in Generic Frontend Server. Patch
451 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
452 sortKeys - or NULL if none is provided.
454 Fixed bug #307: It was impossible to specify indefinite/no timeout
455 for ZOOM_event. Special timeout value -1 now means indefinite timeout
458 Added support for multiple languages and charsets to be specified in
459 ZOOM. Each charset/language is separated by a blank. If negotiation is
460 in effect in init-response, Option
461 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
462 Code based on patch by Vasiliy Osadchuk.
464 Fixed bug #306: infinite recursion that occurred when calling
465 yaz_log_level_init as the first call (before other log level or
468 Fixed bug in scan handling in front end server: if preferred-Position-In-
469 Response was non-present, a NULL pointer referece was performed.
473 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
474 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
475 now defined for all those error codes. So instead of putting 109 in
476 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
477 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
479 Modified the yaz-marcdump utility to skip garbage bytes between MARC
482 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
484 Program yaz-client now exits and produces an error message if multiple
485 Z39.50 servers are specified on the command line (none or one allowed
488 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
493 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
495 Fixed bug #272: Preserve spacing for CCL terms.
499 Added support for virtual hosts and multiple backend servers for
500 the YAZ frontend server. The configution is XML based and
501 support specificition of CQL to RPN mappings and explain information.
502 See section "Virtual Hosts" in the YAZ manual.
504 Extended OPAC display utility. OPAC display utility renders
505 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
506 to supplement yaz_marc_decode_wrbuf.
508 Fixed a bug in MARC decoder that could caused it to crash for some
509 invalid MARC records. More diagnostics and warnings where added in
510 XML output (warnings, etc are stored in comments).
512 --- 2.0.34 2005/02/08
514 Fixes for UNIX domain sockets. Bug #261.
516 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
518 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
519 Added yaz_marc_subfield_str which defines subfield lead string which is
520 used in YAZ_MARC_LINE format. Default string is blank+$. Added
521 yaz_marc_endline_str which defines end of fields string used in
522 YAZ_MARC_LINE format. Default string is newline.
524 Experimental support for MarcXChange. This format can be produced
525 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
526 http://www.bs.dk/standards/MarcXchange.xsd
528 Added yaz-client commands scansize that sets maximum number of
529 entries to be returned by scan.
531 --- 2.0.32 2005/01/11
533 Added support for SRW scan in yaz-client and Generic Frontend Server.
535 * Added whereInList member to SRW Scan Term.
537 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
539 Fixed NMEM system to return aligned blocks on the smallest boundaries
540 that are suitably aligned for all possible types on the particular
541 architecture YAZ is being built for.
543 --- 2.0.30 2005/01/04
545 Fixed numerious warnings that was issued with newer versions of GCC.
547 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
548 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
551 Make YAZ Generic Frontend Server slightly faster.
553 Enhance (and reduce) logging for Generic Frontend Server.
555 Revert YAZ log system so that it flushes every write operation
556 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
558 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
559 instead of LOG_, due to name clash with syslog(3). LOG_ are still
560 present. New applications should define YAZ_USE_NEW_LOG=1 - this
561 will effectively disable old definitions.
563 --- 2.0.28 2004/11/09
565 Added yaz_log_time_format which specifies log format using
568 Added yaz_log_module_level which returns mask for a module. Value
569 is non-zero mask a if module is enabled; zero if disabled.
571 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
572 in include/yaz/cql.h.
574 Fixed bug #176: Dont throw diagnostics on empty SRU args.
576 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
578 Fixed bug #172: RPM builds does not enable SSL.
580 Doxyfile.in part of dist. Doxyfile generated by configure.
582 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
583 are given and the corresponding component does not exist.
585 Extend CCL documentation in YAZ reference. Describe r=r.
587 --- 2.0.26 2004/10/01
589 Fixed MARC->MARCXML conversion to properly deal with
590 fields, subfields, indicators having non-ASCII characters.
592 Fixed MARC->MARCXML conversion so that ASCII control characters
593 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
596 Added YAZ GFS support for conversion from Z39.50 surrogate
597 diagnostics to SRW surrogate diagnostics.
599 Bug fix: YAZ GFS did not return schema in explainResponse.
601 --- 2.0.25 2004/09/30
603 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
604 now converts recordSchema to elementSetName as well as schema URI.
606 Fixed bug in COMSTACK that prevented HTTP request packages from being
609 --- 2.0.24 2004/09/29
611 Added CCL facility r=r "range" which is similar to r=o "ordered" but
612 does not require white-space before and after the dash in a range, e.g.
613 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
616 Fixed a few AC_TRY_LINK configure tests that did not operate properly
617 due to new GCC removing "redundant" code.
619 Added yaz-client commands scanpos and scanstep that sets preferred
620 position and step-size for scan.
622 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
624 Added CCL utility ccl_qual_buf which parses one or more CCL
625 spec lines in a buffer.
627 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
628 of name and value - ignoring empty lines and comments.
630 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
632 Added odr_get_element_path which returns current element path for an
633 ODR handle. This utility is useful in error handling or user-defined
636 Added ODR_PRINT utility odr_set_stream which is is a more generic
637 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
638 to a write function and pointer to close function. The close function - if
639 non-NULL - will be called during odr_destroy.
641 Fixed bug in CCL parser where truncation char was not removed from
642 right side when truncation=both was in effect.
644 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
647 --- 2.0.23 2004/08/11
649 Fix buffer overrun in CQL parser when dealing with proximity (%).
651 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
652 to UTF-8/UCS conversion is now only based on codetables.xml.
654 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
656 --- 2.0.22 2004/08/06
658 Add support for more "commit changes" in ZOOM (uses Extended Services).
660 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
663 Yet another small fix for configure of SSL.
665 --- 2.0.21 2004/05/14
667 Fix SSL libs for configure when --with-openssl=DIR is given.
669 --- 2.0.20 2004/05/10
671 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
673 SSL comstack now uses yaz.pem certificate file on server side
674 by default. Certificate filename can be configured by calling
675 comstack function cs_set_ssl_certificate_file before cs_bind is used.
677 Fix bug regarding multiple calls to ZOOM_connection_connect.
679 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
681 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
682 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
684 ZOOM now allows inspection of X509 peer certificate for verification.
685 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
687 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
688 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
689 as "modular" but it simplifies things.
691 Added cs_get_peer_certificate to that returns peer X509 PEM.
693 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
694 NULL if SSL is unavailable.
696 Documentation about MARC decoding tools.
698 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
700 --- 2.0.19 2004/03/30
702 Rename CHANGELOG to NEWS to follow GNU style packing.
704 Fix bug with missing initialization of member in init_diagnostics.
705 This bug affects threaded version of GFS server.
707 --- 2.0.18 2004/03/20
709 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
712 Ensure zlib.dll is packed with Windows install.
714 --- 2.0.17 2004/03/17
716 Fix encoding of xsd:string to use text instead of CDATA.
718 Fix endless loop in CQL parser with unbalanced ".
720 Use a more compact way to store MARC-8 conversion tables.
722 --- 2.0.16 2004/03/16 Debian only
724 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
727 Update CQL parser to use new CQL 1.1 modifiers for booleans and
732 --- 2.0.15 2004/03/01
734 Another fix for decoding of XML packed records.
736 --- 2.0.14 2004/02/25
738 Fixes for Chunked encoding. White space not ignored after length spec.
740 Update NS and use default NS for SRW diagnostic elements.
742 --- 2.0.13 2004/02/23
744 Implement ZOOM_resultset_cache_reset which resets record cache.
746 Implement ZOOM_resultset_sort which sorts a result set.
748 Implement chunked HTTP transfer.
750 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
752 --- 2.0.12 2004/02/16
754 Added member 'schema' to bend_explain_rr structure so that backend
755 can specify explain record identifier. Defaults to Zeerex 2.0.
757 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
759 --- 2.0.11 2004/02/16
761 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
764 Added init command for yaz-client which sends "extra" init request.
766 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
767 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
769 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
771 Make ZOOM error code for "invalid query".
773 Fixed compilation for SSL which wasn't properly enabled for all platforms.
775 --- 2.0.10 2004/02/05
777 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
780 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
782 Added option -p <file> to make Generic Frontend Server to write PID file.
784 Added option -D to put Generic Frontend Server in background on its own.
786 Make ZOOM C recognize option "password". If unset, "pass" is used
787 (for backwards compatibility).
789 Fixed a bug in Generic Frontend Server that could make it crash if a
790 client sets characterSetNegotation bit, but didn't pass negotiation stuff
793 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
794 Must be issued before open, in order to be in effect.
796 --- 2.0.9-6 2004/01/12 Debian/Windows
798 Make the SRU server more picky WRT unknown params, etc.
800 Bug fix: ZOOM scan response didn't return displayTerm - when present.
802 New YAZ client command, options, that sets Z39.50 options.
804 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
805 options from a string of tokens (one token for each option bit).
807 Update SRW diagnostic code messages.
809 --- 2.0.9-5 2004/01/07 Debian/Windows
811 Handle user defined stylesheet for SRW/SRU.
813 --- 2.0.9-4 2004/01/06 Debian/Windows
815 Fix bug in decoding of Content-Length.
817 --- 2.0.9-3 2004/01/06 Debian/Windows
819 Fix a bug with decoding of XML packed records.
821 --- 2.0.9-2 2004/01/05 Debian only
823 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
825 Fix bug in SRW/SRU diagnostics decoding.
829 Fixed bug in Generic Frontend Server which could drop records exceeding
830 preferred message size. Reported and fixed by Irina Dijour.
832 Fixed calculation of package size for structured records in Generic
833 Frontend Server. Reported and fixed by Irina Dijour.
835 Fixed namespace for SRW/SRU diagnostics.
837 Fixed SEGV in yaz-client that occured for HTTP connection errors.
841 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
842 this version is incompatible with version 1.0 and older YAZ SRW/SRU
845 CQL changes to reflect recent changes to the specification:
846 * Documentation talks about context sets instead of index sets.
847 * Documentation talks about indexes instead of qualifiers.
848 * The CQL-to-PQF transformer's configuration file now uses
849 "index.set.name = <attributes>" instead of the old form
850 "qualifier.set.name = <attributes>". (Both forms are still
851 understood but the latter is deprecated.)
852 * CQL terms with no explicit index specified are now interpreted as
853 cql.serverChoice instead of srw.serverChoice (which of course
854 behaves exactly the same.)
858 MARC conversion can now generate ISO2709 output in another
859 character set. yaz-marcdump uses this facility if you invoke it
862 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
863 functions from there can be used from C++.
867 Frontend server now transfers memory from decoded packages to stream
870 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
871 references to show up.
873 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
874 the ZOOM Abstract API. The older names for the same options are still
875 also supported for the benefit of old applications.
877 ZOOM-C supports "implementationId" and "implementationVersion" options
878 to go along with "implementationName". These allow the user code to
879 specify identification strings to be sent to servers.
880 Add OID for the new ExtLite attribute set.
882 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
883 as requested/supplid by Ere Maijala <ere@atp.fi>
885 For generic frontend server, reverse the order of
886 "toolkit-supplied / application-supplied" strings sent as implementationId,
887 Name and Version. Also, remove the spaces around the slash. This brings
888 the GFS in line with the behaviour of ZOOM-C on the client side.
890 Add function ZOOM_scanset_display_term.
892 yaz-client shows scan displayTerm if present.
894 Utility yaz-iconv is now installed by default along with the man page
897 Extend configure check for OpenSSL to use pkg-config where available (such
900 Incorporate patch by Morten Bogeskov which allows a Unix file socket
901 server to specify uid/gid/mask for socket using the format
902 unix:[user=uid,][group=gid,][umask=mask,]file=path
903 If file= is omitted the existing format is assumed, e.g.
905 in which case the mask is 0666 (rw for everybody).
907 Major restructure of YAZ source. All source in libyaz is in src directory.
908 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
909 util (utility programs such as ASN.1 compiler, yaz-marcdump).
911 Added man page for utility yaz-marcdump (used to be called marcdump).
912 yaz-marcdump is installed by 'make install'.
914 Fixed a memory leak in Generic Frontend Server that occurred when decoding
915 of incoming package failed.
917 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
919 Change prototype of odr_perror: add const to message string.
921 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
923 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
924 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
925 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
926 DNS lookup. There should not be any compatibility problems with this
927 assuming that blocking=1 or 0 is used.
929 Fix bad reference in UNIX comstack in function cs_addrstr.
931 Fix for compilation on AIX.
933 The generic front-end server (server/seshigh.c) now supports returning
934 Init diagnostics to the client in User-information-field, in
935 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
940 Allow any CQL relation (not just all,any,exact,scr).
942 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
943 that features the same UI.
945 Implemented command update0 in YAZ client which is equivalent to
946 update but uses old of Ext Update ASN.1.
948 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
949 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
950 Previously no OID was used for this info.
952 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
953 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
954 returns 'malformed search term' otherwise.
956 SortResponse member resultCount now set to NULL in sort handler of
959 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
962 Add three new utility functions for translating OIDs between various
963 formats -- symbolic name such as "Usmarc", minus-1-terminated int
964 arrays and dotted strings such as "1.2.840.10003.9.5.1":
965 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
966 char *oid_to_dotstring(const int *oid, char *oidbuf);
967 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
969 Reverted modifications for ES Update definition for z_IU0Update
970 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
971 is back to YAZ 2.0.2.
973 String value attributes for CCL parser.
975 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
976 which their FirstSearch server returns in Init responses, sometimes
977 carrying useful diagnostic information when Init fails. This has the
978 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
979 "z39.50/oclcui.asn", where its definition is somewhat different from
980 what OCLC document on their web-site, as required to interoperate with
983 Support for anonymous authentication in yaz-client. Use the command
986 * Fix the OID of the Index Data-local "admin" Extended Service from
987 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
988 the 1000, which indicates a locally-defined OID, was a mistake.
992 Fix CCL directive @case handling so that it affects string match for
993 both CCL keywords and qualifiers.
995 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
996 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
997 Decoder has been updated with ASN.1 changes as listed in
998 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
999 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1000 z_IUUpdate, remains unchanged.
1002 ZOOM_record_get may now return a record in a specific character set.
1003 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1004 "from" is the character set of record as returned by target. "to" is
1005 the character set to be returned. If omitted, "to" is UTF-8.
1007 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1009 New ODR utility, odr_getelement, which returns name of element for
1010 which encoding/decoding failed.
1012 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1013 in cases where a required element was omitted.
1015 Bug fix: some MARC8 sequences were not converted.
1017 New ZOOM option "step" which specifies number of records to be
1018 retrieved in one chunk. Used in conjunction with "start" and "count".
1020 SRW support for yaz-client. Use scheme http: to use it, e.g.
1023 yaz-client no longer does (un)intelligent character set conversions
1024 by default. Can be enabled with charset and marc_charset commands.
1026 xmalloc trace fix for 64-bit systems such as DEC alpha.
1028 Solaris 2.6 compile fix.
1030 New function, cql_strerror() translates SRW error codes, as returned
1031 by cql_transform_error(), into human-readable English strings. Used
1032 in yaz-client diagnostics when appropriate.
1034 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1035 converts it into a type-1 query which is sent to the server. This
1036 makes CQL available for use with all Z-servers, as opposed to the tiny
1037 minority that can handle CQL queries themselves.
1039 --- 2.0.2 2003/04/28
1041 New Debian package layout similar to the Redhat Package layout.
1043 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1044 and search result respectively.
1046 --- 2.0.1 2003/04/25
1048 Redhat package is now several packages: libyaz (runtime libraries),
1049 libyaz-devel (development and documentation, and yaz (utility programs).
1050 Package spec file by Morten Bøgeskov.
1052 New member 'schema' in struct bend_fetch_rr which the name of requested
1053 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1054 handler MAY set this to reflect the schema of the returned record.
1056 New member 'display_term' in struct scan_entry. GFS now sets member entries
1057 and allocates scan entries to be filled by user scan handler. In previous
1058 version, entries member was allocated by the scan handler. That still works,
1059 but the GFS will ignore member display_term - assuming it was NOT set by
1060 the handler. The fact that the GFS now allocates the entries both allows
1061 for new members and makes a scan handler easier to write.
1063 Fix CQL lex buffer overflow.
1065 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1066 SRU default recordPacking is string.
1068 SRU protocol support for frontend server.
1070 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1072 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1074 Added scan for the ZOOM shell (zoomsh).
1078 * String Identifers for Schemas (Amendment 5).
1079 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1080 Old definition for schema
1081 Odr_oid *schema; /* OPT */
1086 Z_InternationalString *uri;
1087 #define Z_Schema_oid 1
1088 #define Z_Schema_uri 2
1091 * resultCount parameter to Sort Response (Amendment 1).
1092 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1094 Support for SRW 1.0 over HTTP. This is an optional feature and
1095 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1098 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1099 on the same port. SRW SearchRetrieveRequests are mapped
1100 to bend_init,bend_search,bend_fetch,bend_close.
1102 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1104 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1105 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1107 ZOOM connections are SRW based if schem http is used for hostname
1108 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1109 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1111 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1112 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1113 distance=n, order=true/false, relation=le, prox unit=word. If
1114 n is omitted, distance 1 is used.
1116 Fixed problem with C compiler include path in wrong order.
1118 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1119 on Solaris. Patch from Ko van der Sloot.
1121 New MARC decode API. All new functions operate on a yaz_marc_t
1122 handle. The most important new functions are: yaz_marc_create,
1123 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1124 decode and destroy respectively. Decoder can produce formats
1125 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1126 include/yaz/marcdisp.h.
1128 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1129 to UTF-8, UCS-32, wchar_t or Latin-1.
1131 * Prototypes for yaz_iconv_-functions moved to separate header
1132 include/yaz/yaz-iconv.h.
1134 Make a few private functions 'static' in unix.c. This prevents
1135 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1137 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1138 are set when Init Response is received.
1140 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1141 but returns diagnostic set as well.
1143 New function yaz_strerror which is a portable wrapper for
1144 strerror/strerror_r/GetLastMessage.
1146 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1147 is returned for MARC. If type is "oai", then OAI MARC is returned.
1149 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1152 --- 1.9.2 2002/11/26
1154 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1156 Fix bad race conditions on SIGTERM and terminate gracefully in
1159 Move retrieval (data1) module to Zebra since nobody seems to be
1162 Add GRS-1 render for ZOOM using same format as yaz-client.
1164 --- 1.9.1 2002/10/05
1166 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1168 Fix broken ESpec handling in data1 module.
1170 SGML reader parses comments and makes them part of the data1 tree.
1172 Added several type casts so that YAZ compiles as C++ code.
1174 ZOOM didn't handle PDU encoding failures properly.
1176 Added more Bib-1 diagnostics (approved extensions).
1178 GNU configure: better check for iconv.
1180 More portable use of accept, getpeername. Check for socklen_t. Use
1181 int/size_t if socklen_t is not defined.
1185 PQF parser rejects bad queries - including those with extra
1186 characters in them. PQF parser used to silently ignore that.
1187 Cleaner API for PQF added, which allows you to get detailed
1188 error information for bad queries (see yaz/pquery.h).
1190 Fixed bug in ZOOM_record_get for type "database".
1192 Implemented mini iconv library supporting conversions between
1193 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1195 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1197 --- 1.8.9 2002/08/20
1199 Fixed ZOOM C record cache so that preferredRecordSyntax and
1200 elementSetName is used to check for already fetched records.
1202 --- 1.8.8 2002/08/02
1204 Added three members in bend_initrequest structure to facilitate
1205 character set negotiation.
1207 Fixed a bug in frontend server that could cause indefinite
1208 loops under rare conditions.
1210 Revised character set utilities (charneg.h) so that encoding
1211 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1213 For PQF, directive @term <type> sets term type for Scan/Search.
1214 Here <type> is general, string, numeric, null. The term type
1215 is inherited - just like @attr.
1217 New call odr_set_charset that sets character set conversion for
1218 international-strings on a ODR stream. Prototype is:
1219 int odr_set_charset(ODR o, const char *to, const char *from);
1220 The InternationalString is still represented as C string in YAZ
1221 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1222 won't). On the protocol level, you can use any encoding.
1224 Support for UNIX sockets in ZOOM.
1226 Solaris recv sometimes returns errno == ENOENT. It is treated as
1227 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1229 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1230 both client and server. Code by Morten Bøgeskov.
1232 --- 1.8.7 2002/05/22
1234 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1235 that they can be used directly from Visual Basic. You must recompile
1236 your windows APP if you're using ZOOM.
1238 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1239 Commands "lang" and "charset" sets language and character set respectively.
1240 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1241 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1243 Attributes from multiple CCL fields may be OR'ed rather than merged
1244 using directive "@field or". Fields are still merged by default -
1245 equivalent to "@field merge".
1247 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1250 Fixed bug in zget for parameter ExtendedServicesResponse.
1254 --- 1.8.6 2002/03/25
1256 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1258 Client displays USR.1:SearchResult-1 (hits per term).
1260 Additional Search Info for search in Generic Frontend Server.
1262 Fixed CCL parsing of "field=s".
1264 WIN32 installer - using the excellent NSIS software from nullsoft.
1266 Fixed CCL parsing of "field = - <number>".
1268 Added function yaz_marc_decode that decodes MARC for line mode
1269 display or XML (similar to that used by JZKit).
1271 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1272 Z39.50. But ISO/ILL was, however.
1274 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1275 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1280 --- 1.8.5 2002/02/03
1282 New YAZ client features: Command completion and new commands:
1283 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1284 Code provided by Jacob Poulsen.
1286 New call oid_trav, that visits all registered OIDs via callback.
1288 Function ZOOM_record_get now returns const char pointer rather than
1289 void pointer. It saves a lot of type casts.
1291 For YAZ client, command "auth" now allows you to set authentication
1292 in IdPass style. It is enabled when three tokens are given - order
1293 is user, group and password.
1295 Fix memory leaks in MARC record handling for ZOOM.
1297 New option for YAZ client, -k <kilobytes> that sets
1298 maximum record size. Similar to -k option for generic frontend
1299 server and yaz-ztest.
1301 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1303 Prefix query parser reports "fail" when bad attribute set is given.
1305 Fix in MARC decoder. Proximity logging. Fix for attribute set
1306 in scan handler for server. Patches by Shigeru Ishida.
1308 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1311 Configure option --with-openssl=<dir> now works when a directory is
1312 specified. Patch provided by Morten Bøgeskov.
1314 New option for YAZ client, -u <auth>, that sets authentication.
1316 ZOOM fix: error information was sometimes "missing", since error
1317 was cleared/reset too when it shouldn't.
1319 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1321 --- 1.8.4 2002/01/04
1323 Scan for ZOOM API. New object ZOOM_scanset. New functions
1324 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1325 ZOOM_scanset_destroy.
1327 New ZOOM function, ZOOM_connection_last_event, that returns type
1328 of last event (such as "receive data", "send data", "apdu received",
1331 New ZOOM option, schema, that specifies schema for retrieval.
1333 New CCL feature. Qualifiers can be aliases for one or more
1334 other qualifiers (if more than one is given, OR is used).
1336 ZOOM uses named result sets if target supports it.
1338 Two new YAZ client commands: . (dot, which sources a script of YAZ
1339 client commands), and ! (to execute shell command.). Implemented
1342 Working on Debian packages.
1344 --- 1.8.3 2001/11/19
1346 YAZ client enables named result sets only if target supports it.
1348 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1350 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1351 with key="host" to get same result.
1353 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1354 Function Z3950_resultset_record(s) returns references to records
1355 "owned" by resultset. To become owner use Z3950_record_clone.
1357 Function z_ext_record handles Extended Services. Thanks to
1360 --- 1.8.2 2001/11/12
1362 CCL Parser fix: ignore token comma when dealing with and-lists.
1364 Documentation updates for COMSTACK.
1366 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1367 Changed prototype Z3950_records. For some functions, int parameters
1368 were changed to size_t.
1370 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1373 New MARC decode/display function, marc_display_exl, which properly rejects
1374 non-ISO2709 records. YAZ client uses it.
1376 --- 1.8.1 2001/10/29
1378 Fix bug: local attribute set wasn't set correctly in PQF strings.
1382 * Old Z39.50 codecs no longer supported.
1384 Added ZOOM C binding. See http://zoom.z3950.org/
1386 Renamed states for COMSTACKs to avoid confusion with events.
1388 Implemented cs_look and proper cs_rcvconnect.
1390 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1392 Configure detects POSIX threads on OpenBSD.
1394 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1395 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1397 When error is returned from present handler, non-surrogate diagnostic
1398 is returned in present response (and fetch handler is no longer called).
1400 * Minor adjustments to pquery parser (PQF). Token characters may be
1401 escaped by using backslash (C-style).
1403 PQF parser allows string attribute values to be specified. For @attr,
1404 non-numeric characters after the equal-sign are treated as strings
1405 (e.g. @attr 9=title).
1407 CCL trunction character may be defined (@truncation in file)
1409 * function zget_ExtendedServicesRequest sets waitAction to
1410 waitIfPossible (was wait).
1412 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1415 CCL operator names may be set in field definition files (CCL_bibset).
1416 See ccl/bib1 for an example.
1418 Fixes in ASN.1 compiler for C++ compatibility.
1420 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1421 and "op_or" to avoid conflict with C++.
1423 Fixed problem with GNU readline detection on Redhat 7.0.
1425 Added step-size for Scan backend handler.
1427 Fixed bug that made the frontend server crash when no attribute
1428 set was specified for scan.
1430 Front-end server automatically switches to original working directory
1431 when installed as an NT service. Previously -w had to be specified to
1434 Added extended attributes for retrieval module (data1), so that data1
1435 records carry d1_readXML/SGML attributes. d1_read also supports
1436 null-data rules ( <tag/>)
1438 On UNIX when POSIX threads are available, a separate library libyazthread
1439 is created. Programmers should link with that library and the yaz library
1440 when using threads. The reason for the split was that some applications
1441 on Linux, such as Apache, doesn't work well when using shared objects that
1444 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1445 (or any frontend server) in SSL mode by specifying ssl: followed by
1446 address. Only tested on UNIX.
1448 Added feature for CCL module. Virtual structure s=al or s=ol generates
1449 and-list and or-list respectively instead of phrase search.
1453 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1454 log_mask_str. This was done to avoid name conflicts with other libraries
1455 (such as other PHP extensions).
1457 Added raw OID member for preferred record syntax (request_format_raw)
1458 and returned record syntax (output_format_raw) for backend fetch method.
1460 Config file yaz-config now accepts options so that it returns specific
1461 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1463 Shared library support for UNIX using GNU libtool.
1465 * Modified backend interface. Request/Response struct's replaced by
1466 one read/write C struct. For example bend_fetchrequest and
1467 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1468 Every handler - even search has to be registered in bend_init
1469 handler. This means that the YAZ library no longer refers to
1470 external functions and it makes it possible to make the whole
1471 thing a single DLL/SO.
1473 Added Segment handler for backend server.
1475 Added Zmbol/Zebra administrative functions to YAZ client.
1477 Threaded frontend server on UNIX (when POSIX Threads are available).
1478 Starting the server with option -T enables multi-threading.
1482 Added configure option --enable-comp/disable-comp to control use
1483 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1484 located in sub directory asn.
1486 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1487 in ${exec_prefix}/bin along with the other programs yaz-client and
1490 GNU automake used to maintain makefiles.
1492 Added several OID's.
1494 Changed retrieval module so that we can load records with no abstract
1495 syntax defined. Tagpaths in these records are fully composed of string
1498 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1502 On UNIX, the generated makefile now supports a proper 'make install'.
1503 The prefix can be set via GNU configure to set the install location
1504 (default is /usr/local).
1506 * YAZ programs client and ztest were renamed to yaz-client and
1507 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1508 locations, such as /usr/bin,/usr/local/bin,etc.
1510 * YAZ Header files were moved from include to include/yaz. YAZ Header
1511 files are referred to as include <yaz/log.h> rather than <log.h>.
1512 The YAZ include path (-I ..) is therefore the same as before. Programmers
1513 should update their #include statements or use -Ipath/include/yaz
1514 instead. The main motivation for doing this change is that YAZ header files
1515 can be installed in "standard" locations /usr/include,/usr/local/include
1516 without introducing conflicts, since ALL YAZ header files are stored
1517 in subdirectory yaz (under /usr/include for example).
1519 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1520 rather than project/workspace files. We switched because project files
1521 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1524 Changed name of logging function, logf, to yaz_log, to prevent name
1525 clash with some math-log functions. The YAZ header log.h defines logf
1526 to yaz_log (#define) so there should be no incompatibilities by this
1529 Added bend_start/bend_stop handlers for server. These handler are
1530 called on start/stop of server. For windows they are called whenever
1531 a service is started/stopped.
1533 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1534 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1535 in util/yc.tcl. The auto-generated C code structures are, in a few
1536 cases, incompatible with the old decoders. There are differences in the
1537 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1538 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1539 The preprocessor variable ASN_COMPILED is defined when the compiled
1540 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1541 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1542 wish to use the old encoders/decoders you can specify --disable-yc
1545 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1546 version so that it supports both new - and old version of DB Update
1548 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1549 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1550 change. The name parameter can be set to 0 in which no name is specified
1551 for the construction. The macros odr_implicit and odr_explicit sets name
1552 parameter to zero for the construction involved. New macros
1553 odr_implicit_tag and odr_explicit_tag are similar to the others,
1554 except that a name parameter is added. For programmers' that don't use
1555 ODR they probably only need to change the call to z_APDU and z_External.
1557 Added access control facility by interfacing the TCP wrapper library.
1558 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1559 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1560 name of the daemon and enables the access control as specified in
1561 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1563 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1564 den Dool <H.M.vdnDool@kub.nl>.
1566 Added reference ID parameter to most functions in server API - refer
1567 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1569 Changed name of ccl library to libccl.a (was ccl.a).
1571 Fixed bug in decoder for Explain (Category TargetInfo).
1573 Added support for GNU readline in client. Thanks to Jacob Poulsen
1574 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1576 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1577 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1578 IMPLEMENTATION! This change was made to the development version before
1579 the ZIG decided to retract the amendment. If any users MUST be
1580 compatible with the original Update definition, PLEASE CONTACT US, and
1581 we will include a separate definition corresponding to the old Update
1582 ES. Note that because of the change to the ASN.1 of the
1583 TaskPackageRecordStructure we cannot define a single structure that
1584 will support both versions.
1586 * Added const modifier to buffer parameter for some ODR/BER encoding
1587 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1588 completeWAIS, odr_dumpBER.
1590 Fixed bug in client.c which caused a crash when a scanResponse didn't
1591 contain positionOfTerm.
1593 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1594 * will cause an error in a client if a non-YAZ target sends both a
1595 * list of Scan entries and non-surrogate diagnostics.
1597 Retrieval module enhancements. Tag sets may be typed in the reference
1598 to it. From the .abs-file the "tagset" directive takes a third optional
1599 integer type for the tag set referenced. From a .tag-file the "include"
1600 directive takes a third optional type as well. The old "type" directive
1601 in the tag set itself is still recognized but acts as the default type
1604 Backend interface change. Individual Scan terms returned from bend_scan
1605 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1606 in include/backend.h.
1608 Retrieval module enhancements. Multiple tag sets and attribute sets may
1609 be specified in abstract syntax specs. Revised the error/warning for
1610 logging messages reported by the retrieval module when reading the
1613 Object Identifier system (oid_..) changed. The API is backwards
1614 compatible but the oid-routines now allocates new OID's when needed.
1615 Raw OID's may be specified in oid_getvalbyname.
1617 YAZ now uses GNU configure to generate Makefile(s).
1619 * Minor changes in some of the member names of DeleteResultSetRequest and
1620 DeleteResultSetResponse. See include/proto.h.
1622 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1623 and added member 'languages' in TargetInfo (which was missing).
1625 Changed the way attribute sets are handled in the retrieval
1626 module. These are now cached, just like the abstract syntaxes
1629 Changed YAZ so that it links with compiled ASN.1.
1631 Added Explain-schema definitions and mapping routines. The following
1632 Explain categories have been implemented: AttributeDetails,
1633 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1635 Fixed minor bug in Windows version of Server Library.
1637 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1639 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1641 Added EXTERNAL: UNIverse Resource Report (non-standard).
1643 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1644 ENUMERATED and SET OF.
1646 * Added 'const' to some of the char pointer arguments for the
1647 functions, data1_read_node, data1_getelementbytagname,
1648 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1651 Fixed bug in data1_insert_taggeddata - the last_child member of
1652 parent wasn't initialised.
1654 * Changed data1_read_record and data1_read_node so that the supplied
1655 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1656 doesn't refer to any parts of the "SGML"-buffer.
1658 Fixed bug in server library (Windows version of statserv_remove).
1660 * Changed code so that it compiles as C++. The type definition
1661 of Odr_fun which is a member of Odr_arm was changed. The result is,
1662 that an explicit typecast is needed for the fun pointer when
1663 using Odr_arm - as in:
1664 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1666 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1668 Implemented the new structured date and time definition as approved
1669 by the ZIG. Added schemaId element to the specificTag in Espec-1
1670 (also approved at the last ZIG). Thanks to RVDM.
1672 Added some Object identifiers (RVDM).
1674 Changed the Update Extended Service (RVDM).
1676 Added command "refid" to client which specifies referenceId for
1677 the following requests.
1679 Implemented extended service handling for server. See ztest.c
1680 for an example as well as backend.h. New handlers are registerd
1681 in the Init handler.
1683 * Changed interface for sort in server.
1685 Added new members to statserv_options_block. It allows a server
1686 to read options from another source than just the command line. Thanks
1687 to Charles Woodfield.
1689 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1690 renamed to zboolean. Some C++ compilers complained about the name.
1692 Minor changes to gils.abs. Added index 's' (sort) on title
1693 and date/time-last-modified.
1695 --- 1.4pl2 1998/1/30
1697 Fixed bug in server library regarding inetd mode (-i). This bug
1698 was introduced by release 1.4.
1700 --- 1.4pl1 1998/1/29
1702 Added sort facility in client and backend server interface.
1704 Fixed problem with dependencies in Makefile(s).
1706 Fixed bugs for encoders/decoders of extended services and
1709 Implemented sub-tree feature for schemas. Sub-trees are
1710 referenced in *.abs-files. See explain.abs for an example
1711 of the use of this feature.
1713 Modified bib1.att; local attributes for ANY didn't include
1714 ANY itself (only affects use of the retrieval module).
1716 Fixed bug in plain SGML reader in function data1_read_node:
1717 tags with prefix "var" was incorrectly interpreted as variants.
1719 Added feature "sub-schemas" to enable references to - and definitions
1720 of - group of elements.
1722 * Removed member parent from type data1_element (in data1.h).
1724 Implemented function odr_nullval() that returns the value of
1727 * Removed member num_children from data1_node (in data1.h).
1729 Made NT service interface part of the server library. The
1730 function statserv_main uses the NT service when required and
1731 calls the statserv_start / statserv_close routines.
1733 Routine zget_SearchRequest and zget_PresentRequest fills
1734 resultSetName/Id member with "default" instead of "Default".
1736 Fixed memory leak in server. Request queue member wasn't freed.
1738 Fixed nmem_exit so that memory is freed.
1742 Revised the CCL parser utility to be thread safe.
1744 Added function, oid_ent_to_oid, to replace the function
1745 oid_getoidbyent, which is not thread safe.
1747 * Added nmem_init and nmem_exit to initialize and release
1748 NMEM resources. Function nmem_init should be called once in the
1749 initial thread before NMEM/ODR is used. statserv.c and client.c
1750 have been changed accordingly. The change was necessary to make
1751 NMEM thread safe. The NMEM memory pool is shared amongst threads
1752 in a process. Unix-based applications will still work fine without
1755 Added NT Services interface for the the Z39.50 (statserv) Server.
1756 Refer to the ztest.c source on the usage.
1758 Windows 95/NT port using MSVC5.0. Project files are included in the
1761 * Defined new 'global' handle for the retrieval (data1) system. The
1762 new handled, data1_handle, describes the state of the data1 system.
1763 This handle is passed as first argument to virtually all
1764 data1 related routines. The functions data1_create and data1_destroy
1765 creates and destroys a data1 handle respectively.
1767 Added ODR encode stream member to all backend request structures
1768 init, search, scan etc. This stream should be used to allocate all
1769 memory used for the response when thread safe operation is needed.
1771 Changed the comstack utility, cs_addstr, to be thread safe. The
1772 returned hostname string returned by the function is now part the
1775 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1776 function. The cs_straddr takes a COMSTACK handle as argument, so this
1777 function must be used after cs_create and before bind/connect.
1778 This function is thread safe.
1780 Moved test server to 'ztest' directory - generic server code still
1781 in 'server' directory.
1783 Made prefix query (pquery.c) utility thread safe.
1785 Added new function modifier YAZ_EXPORT to 'export' public DLL
1786 functions when using windows (see include/yconfig.h).
1788 Added definitions to the OID database (util/oid.c) (RVDM).
1790 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1792 Added call to ccl_rpn_delete in client program.
1794 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1795 release of RPN structure.
1797 Added support for C++, headers uses extern "C" for public definitions.
1798 With input from RVDM.
1800 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1801 Thanks to Ronald van der Meer (RVDM).
1803 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1805 Added support for private extensions to the OID database
1806 (oid_setprivateoids()). Thanks to RVDM.
1808 Added optional, physical ANY (key replication)
1810 Fixed null-reference problem in GRS-1 output filter.
1812 Proximity operator added to Prefix Query Format (PQF).
1814 In test client command "base" accepts multiple databases.
1816 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1820 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1822 Smallish bug-fixes in the new encoders/decoders (explain).
1824 Bug fixed in DeleteRequest.
1826 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1828 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1830 Added SOIF syntax (using private OID for now) to retrieval module and client.
1832 Added Update extended service.
1834 Added SearchResult-1 additional info structure.
1836 Added optional CCL (ISO8777) interpreter as separate module. Available
1839 --- 1.2 1996/6/10 (1st anniversary release)
1841 Added Summary record syntax. Lightly tested.
1843 Added OPAC record syntax. Untested.
1845 Added ResourceReport service encoders/decoders. Untested.
1847 Fixed bug in z_Unit - wrong tagging on unitSystem.
1849 Fixed bug in the DiagRecs decoder.
1851 Added options for max PDU size and session timeout to frontend-server.
1853 Added documentation of query-language parsers and other supporting utilities.
1855 [frontend-server] Added Attribute set to the bend_scanrequest API.
1857 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1858 surrogate diagnostics were generated.
1860 [retrieval] Allow multiple local values for attribute.
1862 [retrieval] Allow multiple attributes per element in .abs files. index type.
1864 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1866 --- 1.1pl2 1996/4/10
1868 Minor changes, mostly specific to Zebra's requirements (retrieval)
1872 Repaired bug in frontend server when running multiple listening
1873 endpoints in dynamic mode.
1875 z_External() now won't break if a known, ASN.1 value comes encapsulated
1876 in an octet-string. The value will pass through unmodified in an Odr_oct.
1878 Added a bit of code to the demo client to decode & display
1879 ASN.1-structured records represented in the octet-aligned branch of
1880 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1882 Added z_ext_getentbyref() to the ASN module. Doc updated.
1884 * Completed the SCAN definition in the ASN module. This may break SCAN
1885 code based on older YAZ-versions at compile-time. The fix is easy -
1888 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1889 under the SCAN definition. Remember to initialize this, server-people.
1891 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1892 that this does not extend to ODR and ASN.
1894 Comstack allows insertion of established socket (primarily for
1895 inetd-operation of servers). Doc updated.
1897 Front-end server can now start from the inetd in TCP mode. Doc
1900 --- 1.0pl4 1996/1/24
1904 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1905 the rank and record number.
1907 Adjustments to the frontend server.
1909 Fixed diagnostic BER dumper. It ignored the file argument.
1913 Various changes to retrieval module.
1915 Changed the union discriminators of the protocol files from enums to
1916 ints paired with #defines.
1918 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1921 *Changed operator in the RPN structure to 'roperator', again to avoid a
1924 Fixed problems in Explain decoders/encoders.
1926 --- 1.0pl2 1995/12/6
1928 Memory bug in log module fixed.
1930 --- 1.0pl1 1995/12/5
1932 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1934 Bug in Explain DatabaseInfo module fixed.
1936 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1940 The shift to v1.0 signals that we now consider the *core* functionality
1941 of YAZ reasonably stable (the core being more or less equivalent to
1942 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1943 tested (Explain not at all - though that will happen soonish).
1945 Minor changes to code to support Windows port.
1947 Various minor changes after we're getting to use GRS-1 & co. more.
1949 Added Espec-1 format.
1951 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1952 of the protocol and it cannot be selected when encoding (maps into 'string'
1953 when decoding). Needed to talk to some servers.
1955 Demo client can request simple element set names.
1957 Added Diagnostic Format encoders/decoders.
1959 Added simple Close handling to frontend server (no hooks for resource
1960 reporting yet), and demonstration client.
1962 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1964 --- 1.0b3 1995/08/24
1966 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1967 handled incorrectly when records were requested in the searchResponse. This
1968 will only affect you if you use the frontend-server.
1970 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1971 Test-client will ask for and print GRS1. Ztest will return dummy records
1974 Added Explain encoders/decoders to the service-level API. Untested.
1976 Added Extended Services: Item Order encoders and decoders to the Service-
1977 level API. Untested. We could use a recent copy of the pertinent bits
1978 of the ILL protocol to add those bits.
1980 Added diagnostic format 1 encoders/decoders to the service-level API.
1983 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1984 odr_cons.c, which causes a more correct output.
1986 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1987 was always set to 0 when no records were requested in the searchRequest.
1989 * Added better external-handling. This shouldn't harm old code that
1990 *encodes* externals. It can break code that looks for a
1991 'single-ASN1-type' representation, since those types that are known
1992 are now decoded immediately. Look at the SUTRS sample code in
1993 seshigh.c and client.c. Documentation updated.
1995 Handling of structured records in bend_fetchresponse. Length -1 marks
1996 structured record, type is deduced from format field.
1998 --- 1.0b2 1995/06/27
1999 Fairly quick maintenance release to add SUTRS support.
2001 Fixed handling of SUTRS records in the demonstration client.
2003 * Added format field to the bend_fetchrequest and bend_fetchresponce
2004 structures of the backend API (frontend server). When the record is
2005 returned, the value of the format field is mapped to an OID. The
2006 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2007 of the record. The special value VAL_NONE in the bend_request means
2008 that no specific format was requested by the client. Documentation
2009 updated accordingly. Test server (ztest) will return a fixed dummy
2010 SUTRS record if your client requests SUTRS.
2012 Documentation updated accordingly.
2014 You can now set external libraries and RANLIB support in the top-level
2018 First public release.
