1 Bug #600: SRU GET, POST support for yaz-client. Introduced
2 command 'sru' which selects method SOAP/GET/POST.
4 Allow missingValueAction to be specified for the sortspec string -
5 function yaz_sort_spec. By default, the missing value action is null.
6 Use ! to specify "abort". Use = followed by stringvalue to specify default
9 Ensured that Present-handler (if defined) is called in GFS before any call to
10 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
11 searchRetrieve requests.
13 Documentation for YAZ is now based on the Docbook XML/XSLT using
14 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
15 is no longer depending on jade/openjade or docbook-to-man scripts.
16 PDF is no longer part of the distribution - but can optionally be
17 made using DSSSL/jadetex or FOP.
19 Added retrieval handling support in Generic Frontend Server to support
20 conversion between MARC/XML as well as XSLTtransforms. See
21 etc/yazgfs.xml for an example.
23 Added Authentication support to Generic Frontend Server in SRU
24 mode. Authentication using HTTP Basic is supported, as is the use
25 of 'x-username' and 'x-password' parameters in the request itself.
27 Added support for a new character set MARC8s identical to MARC8 except
28 that it converts combined characters to single Unicode characters in the
29 Latin-1 range (when possible).
33 ASN.1 compiler 0.4: generates brief Doxygen file header for
34 generated .h/.c files.
36 Utility yaz_iconv now supports conversion to MARC-8.
38 New facilities for the MARC module. The reading - and writing of
39 content are separate methods for the yaz_marc_t handle. The following
40 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
41 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
42 format). Write functions have prefix yaz_marc_write_.. The existing
43 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
44 available. Removed support for OAI-MARC and simplexml (not the
47 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
48 to be returned for this connection.
52 Allow multiple languages and charsets to be specified with
53 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
54 negcharset iso-8859-1,utf-8
56 Translation of proximity nodes from CQL into PQF now works.
58 Moved to automake 1.8, 1.9.
60 Added function yaz_log_set_handler which allows a log handler to be
61 installed. This handler will be called for all log messages. Output
62 to file is also produced; but that can be disabled by passing NULL
63 fname to yaz_log_init_file.
65 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
67 For SRW (including GFS), accept application/soap+xml as content-type
70 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
71 produces NO stylesheet reference even if a default stylesheet is specified
76 Updated Windows package to include yazd.dll + yazd.lib for the
77 Development component.
79 If the environment variable YAZ_LOG is set, then it is used as a
80 string indicating the default level of logging to use if not
81 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
82 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
83 used as before. So, for example, to omit warnings from YAZ logging,
86 cql_transform() now map structure and other attributes before indexes,
87 so that index-specific structures and other attributes can override
88 defaults. So now a combination of mapping specifications such as:
90 index.dc.date = 1=date-modified 4=5
93 cql_transform() now also respects the "always" mapping specification,
94 which establishes an initial set of attributes to be used for all
95 terms except where overridden by more specific attributes associated
96 with the index, relation or modifier.
98 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
99 which mode to use; one of "post", "get" or "soap" (SRW, default).
101 Fixes for yaz_iconv routines: changed trie-based character set conversions
102 to use only non-negative values for bit fields due to Sun's C compiler not
103 supporting negative values.
105 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
106 sequences where not read correctly. Fix by Rustam Usmanov.
108 Updated win/makefile to use options, settings which makes things
109 compile with VS C 2005.
111 --- 2.1.12 2006/02/01
113 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
115 In ZOOM socket code, use select instead of poll on MacOSX.
117 ZOOM-C now support client-side compilation of CQL into RPN that is
118 sent to the server, enabling CQL to be used against all Z39.50
119 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
120 ZOOM_query object, and submit it using ZOOM_connection_search().
121 The CQL-to-RPN translation uses a configuration file, the name of
122 which must be specified in the Connection's "cqlfile" option.
124 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
125 function, which takes as its start-term parameter a ZOOM_query object
126 (which may have had either CQL or RPN set into it).
129 --- 2.1.10 2005/11/29
131 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
132 GFS to support this as well. Backend handler, bend_srw_update, does the
133 update work. Code contributed by Ko van der Sloot.
135 Allow retrieval of Search Result-1 information in ZOOM by the use of
136 options that are attached to a result set. ZOOM documentation updated
139 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
140 UTF-8 conversion. Patch by Raj Patel.
142 Added option -m to GFS to control formatting of timestamps in log file.
144 Added 'exit' as synonym for 'quit' in yaz-client
146 Added support for specifying SRW resultSetId + resultSetIdleTime in a
147 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
148 for the new members. Patch by Ko van der Sloot.
150 Added support for SRU POST. It is supported for content-type
151 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
153 Do not build the separate Multi-threaded (MT) library libyazthread.la.
154 Instead make the library libyaz.la multi-threaded. Threading as a whole
155 can still be disabled by configure option --disable-threads. Previosly,
156 with older GLIBCs there were problems with MT libs under Apache. This
157 has now been fixed a long time ago.
159 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
162 CQL module modified to be case insensitive for relations/indexes/operations.
164 Fixed bug in CQL transform code: incorrect value relationModifieder
167 Added 'show all' command for yaz-client which retrieves all results
170 Added new yaz-client, xmles, which takes a (private) OID and
171 a document to be sent as an extended service request.
173 Describe new yaz-client commands wait_response and set_auto_wait.
175 Increase TCP/IP listener backlog from 3 (which I am guessing was
176 copied from the SunOS manual entry way back when) so SOMAXCONN, so
177 that the socket will queue as many incoming connections as it's able
178 to handle ongoing connections. In other words, it will never now
179 refuse a connection that it would be able to handle merely because
180 it's not got around to accepting() enough of the pending connections
181 yet. This is the behaviour anyway under Linux, where the listen()
182 argument is ignored; but not under BSD and on systems such as
183 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
184 YAZ-based servers should now be uniform across operating systems in
187 yaz-marcdump uses 64-bit file access on some systems. This is enabled
188 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
189 This allows yaz-marcdump to read large MARC batches (>2 GB).
191 Modified all YAZ source files - except the source which is auto-generated
192 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
195 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
196 corresponding to the existing *_setl() function. These allow option
197 values containing arbitrary valuues.
199 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
200 ZOOM_resultset_sort() in new applications. Its behaviour is identical
201 except that it returns an indicator of whether or not the sort
202 criterion was accepted (0 for OK, -1 for invalid).
206 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
207 MARC output rather than returning "new" buffer.
209 yaz-client warns about unknown init options.
211 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
215 Added support for SRW sort in Generic Frontend Server. Patch
216 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
217 sortKeys - or NULL if none is provided.
219 Fixed bug #307: It was impossible to specify indefinite/no timeout
220 for ZOOM_event. Special timeout value -1 now means indefinite timeout
223 Added support for multiple languages and charsets to be specified in
224 ZOOM. Each charset/language is separated by a blank. If negotiation is
225 in effect in init-response, Option
226 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
227 Code based on patch by Vasiliy Osadchuk.
229 Fixed bug #306: infinite recursion that occurred when calling
230 yaz_log_level_init as the first call (before other log level or
233 Fixed bug in scan handling in front end server: if preferred-Position-In-
234 Response was non-present, a NULL pointer referece was performed.
238 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
239 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
240 now defined for all those error codes. So instead of putting 109 in
241 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
242 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
244 Modified the yaz-marcdump utility to skip garbage bytes between MARC
247 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
249 Program yaz-client now exits and produces an error message if multiple
250 Z39.50 servers are specified on the command line (none or one allowed
253 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
258 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
260 Fixed bug #272: Preserve spacing for CCL terms.
264 Added support for virtual hosts and multiple backend servers for
265 the YAZ frontend server. The configution is XML based and
266 support specificition of CQL to RPN mappings and explain information.
267 See section "Virtual Hosts" in the YAZ manual.
269 Extended OPAC display utility. OPAC display utility renders
270 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
271 to supplement yaz_marc_decode_wrbuf.
273 Fixed a bug in MARC decoder that could caused it to crash for some
274 invalid MARC records. More diagnostics and warnings where added in
275 XML output (warnings, etc are stored in comments).
277 --- 2.0.34 2005/02/08
279 Fixes for UNIX domain sockets. Bug #261.
281 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
283 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
284 Added yaz_marc_subfield_str which defines subfield lead string which is
285 used in YAZ_MARC_LINE format. Default string is blank+$. Added
286 yaz_marc_endline_str which defines end of fields string used in
287 YAZ_MARC_LINE format. Default string is newline.
289 Experimental support for MarcXChange. This format can be produced
290 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
291 http://www.bs.dk/standards/MarcXchange.xsd
293 Added yaz-client commands scansize that sets maximum number of
294 entries to be returned by scan.
296 --- 2.0.32 2005/01/11
298 Added support for SRW scan in yaz-client and Generic Frontend Server.
300 * Added whereInList member to SRW Scan Term.
302 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
304 Fixed NMEM system to return aligned blocks on the smallest boundaries
305 that are suitably aligned for all possible types on the particular
306 architecture YAZ is being built for.
308 --- 2.0.30 2005/01/04
310 Fixed numerious warnings that was issued with newer versions of GCC.
312 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
313 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
316 Make YAZ Generic Frontend Server slightly faster.
318 Enhance (and reduce) logging for Generic Frontend Server.
320 Revert YAZ log system so that it flushes every write operation
321 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
323 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
324 instead of LOG_, due to name clash with syslog(3). LOG_ are still
325 present. New applications should define YAZ_USE_NEW_LOG=1 - this
326 will effectively disable old definitions.
328 --- 2.0.28 2004/11/09
330 Added yaz_log_time_format which specifies log format using
333 Added yaz_log_module_level which returns mask for a module. Value
334 is non-zero mask a if module is enabled; zero if disabled.
336 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
337 in include/yaz/cql.h.
339 Fixed bug #176: Dont throw diagnostics on empty SRU args.
341 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
343 Fixed bug #172: RPM builds does not enable SSL.
345 Doxyfile.in part of dist. Doxyfile generated by configure.
347 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
348 are given and the corresponding component does not exist.
350 Extend CCL documentation in YAZ reference. Describe r=r.
352 --- 2.0.26 2004/10/01
354 Fixed MARC->MARCXML conversion to properly deal with
355 fields, subfields, indicators having non-ASCII characters.
357 Fixed MARC->MARCXML conversion so that ASCII control characters
358 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
361 Added YAZ GFS support for conversion from Z39.50 surrogate
362 diagnostics to SRW surrogate diagnostics.
364 Bug fix: YAZ GFS did not return schema in explainResponse.
366 --- 2.0.25 2004/09/30
368 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
369 now converts recordSchema to elementSetName as well as schema URI.
371 Fixed bug in COMSTACK that prevented HTTP request packages from being
374 --- 2.0.24 2004/09/29
376 Added CCL facility r=r "range" which is similar to r=o "ordered" but
377 does not require white-space before and after the dash in a range, e.g.
378 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
381 Fixed a few AC_TRY_LINK configure tests that did not operate properly
382 due to new GCC removing "redundant" code.
384 Added yaz-client commands scanpos and scanstep that sets preferred
385 position and step-size for scan.
387 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
389 Added CCL utility ccl_qual_buf which parses one or more CCL
390 spec lines in a buffer.
392 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
393 of name and value - ignoring empty lines and comments.
395 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
397 Added odr_get_element_path which returns current element path for an
398 ODR handle. This utility is useful in error handling or user-defined
401 Added ODR_PRINT utility odr_set_stream which is is a more generic
402 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
403 to a write function and pointer to close function. The close function - if
404 non-NULL - will be called during odr_destroy.
406 Fixed bug in CCL parser where truncation char was not removed from
407 right side when truncation=both was in effect.
409 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
412 --- 2.0.23 2004/08/11
414 Fix buffer overrun in CQL parser when dealing with proximity (%).
416 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
417 to UTF-8/UCS conversion is now only based on codetables.xml.
419 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
421 --- 2.0.22 2004/08/06
423 Add support for more "commit changes" in ZOOM (uses Extended Services).
425 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
428 Yet another small fix for configure of SSL.
430 --- 2.0.21 2004/05/14
432 Fix SSL libs for configure when --with-openssl=DIR is given.
434 --- 2.0.20 2004/05/10
436 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
438 SSL comstack now uses yaz.pem certificate file on server side
439 by default. Certificate filename can be configured by calling
440 comstack function cs_set_ssl_certificate_file before cs_bind is used.
442 Fix bug regarding multiple calls to ZOOM_connection_connect.
444 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
446 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
447 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
449 ZOOM now allows inspection of X509 peer certificate for verification.
450 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
452 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
453 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
454 as "modular" but it simplifies things.
456 Added cs_get_peer_certificate to that returns peer X509 PEM.
458 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
459 NULL if SSL is unavailable.
461 Documentation about MARC decoding tools.
463 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
465 --- 2.0.19 2004/03/30
467 Rename CHANGELOG to NEWS to follow GNU style packing.
469 Fix bug with missing initialization of member in init_diagnostics.
470 This bug affects threaded version of GFS server.
472 --- 2.0.18 2004/03/20
474 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
477 Ensure zlib.dll is packed with Windows install.
479 --- 2.0.17 2004/03/17
481 Fix encoding of xsd:string to use text instead of CDATA.
483 Fix endless loop in CQL parser with unbalanced ".
485 Use a more compact way to store MARC-8 conversion tables.
487 --- 2.0.16 2004/03/16 Debian only
489 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
492 Update CQL parser to use new CQL 1.1 modifiers for booleans and
497 --- 2.0.15 2004/03/01
499 Another fix for decoding of XML packed records.
501 --- 2.0.14 2004/02/25
503 Fixes for Chunked encoding. White space not ignored after length spec.
505 Update NS and use default NS for SRW diagnostic elements.
507 --- 2.0.13 2004/02/23
509 Implement ZOOM_resultset_cache_reset which resets record cache.
511 Implement ZOOM_resultset_sort which sorts a result set.
513 Implement chunked HTTP transfer.
515 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
517 --- 2.0.12 2004/02/16
519 Added member 'schema' to bend_explain_rr structure so that backend
520 can specify explain record identifier. Defaults to Zeerex 2.0.
522 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
524 --- 2.0.11 2004/02/16
526 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
529 Added init command for yaz-client which sends "extra" init request.
531 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
532 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
534 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
536 Make ZOOM error code for "invalid query".
538 Fixed compilation for SSL which wasn't properly enabled for all platforms.
540 --- 2.0.10 2004/02/05
542 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
545 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
547 Added option -p <file> to make Generic Frontend Server to write PID file.
549 Added option -D to put Generic Frontend Server in background on its own.
551 Make ZOOM C recognize option "password". If unset, "pass" is used
552 (for backwards compatibility).
554 Fixed a bug in Generic Frontend Server that could make it crash if a
555 client sets characterSetNegotation bit, but didn't pass negotiation stuff
558 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
559 Must be issued before open, in order to be in effect.
561 --- 2.0.9-6 2004/01/12 Debian/Windows
563 Make the SRU server more picky WRT unknown params, etc.
565 Bug fix: ZOOM scan response didn't return displayTerm - when present.
567 New YAZ client command, options, that sets Z39.50 options.
569 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
570 options from a string of tokens (one token for each option bit).
572 Update SRW diagnostic code messages.
574 --- 2.0.9-5 2004/01/07 Debian/Windows
576 Handle user defined stylesheet for SRW/SRU.
578 --- 2.0.9-4 2004/01/06 Debian/Windows
580 Fix bug in decoding of Content-Length.
582 --- 2.0.9-3 2004/01/06 Debian/Windows
584 Fix a bug with decoding of XML packed records.
586 --- 2.0.9-2 2004/01/05 Debian only
588 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
590 Fix bug in SRW/SRU diagnostics decoding.
594 Fixed bug in Generic Frontend Server which could drop records exceeding
595 preferred message size. Reported and fixed by Irina Dijour.
597 Fixed calculation of package size for structured records in Generic
598 Frontend Server. Reported and fixed by Irina Dijour.
600 Fixed namespace for SRW/SRU diagnostics.
602 Fixed SEGV in yaz-client that occured for HTTP connection errors.
606 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
607 this version is incompatible with version 1.0 and older YAZ SRW/SRU
610 CQL changes to reflect recent changes to the specification:
611 * Documentation talks about context sets instead of index sets.
612 * Documentation talks about indexes instead of qualifiers.
613 * The CQL-to-PQF transformer's configuration file now uses
614 "index.set.name = <attributes>" instead of the old form
615 "qualifier.set.name = <attributes>". (Both forms are still
616 understood but the latter is deprecated.)
617 * CQL terms with no explicit index specified are now interpreted as
618 cql.serverChoice instead of srw.serverChoice (which of course
619 behaves exactly the same.)
623 MARC conversion can now generate ISO2709 output in another
624 character set. yaz-marcdump uses this facility if you invoke it
627 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
628 functions from there can be used from C++.
632 Frontend server now transfers memory from decoded packages to stream
635 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
636 references to show up.
638 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
639 the ZOOM Abstract API. The older names for the same options are still
640 also supported for the benefit of old applications.
642 ZOOM-C supports "implementationId" and "implementationVersion" options
643 to go along with "implementationName". These allow the user code to
644 specify identification strings to be sent to servers.
645 Add OID for the new ExtLite attribute set.
647 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
648 as requested/supplid by Ere Maijala <ere@atp.fi>
650 For generic frontend server, reverse the order of
651 "toolkit-supplied / application-supplied" strings sent as implementationId,
652 Name and Version. Also, remove the spaces around the slash. This brings
653 the GFS in line with the behaviour of ZOOM-C on the client side.
655 Add function ZOOM_scanset_display_term.
657 yaz-client shows scan displayTerm if present.
659 Utility yaz-iconv is now installed by default along with the man page
662 Extend configure check for OpenSSL to use pkg-config where available (such
665 Incorporate patch by Morten Bogeskov which allows a Unix file socket
666 server to specify uid/gid/mask for socket using the format
667 unix:[user=uid,][group=gid,][umask=mask,]file=path
668 If file= is omitted the existing format is assumed, e.g.
670 in which case the mask is 0666 (rw for everybody).
672 Major restructure of YAZ source. All source in libyaz is in src directory.
673 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
674 util (utility programs such as ASN.1 compiler, yaz-marcdump).
676 Added man page for utility yaz-marcdump (used to be called marcdump).
677 yaz-marcdump is installed by 'make install'.
679 Fixed a memory leak in Generic Frontend Server that occurred when decoding
680 of incoming package failed.
682 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
684 Change prototype of odr_perror: add const to message string.
686 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
688 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
689 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
690 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
691 DNS lookup. There should not be any compatibility problems with this
692 assuming that blocking=1 or 0 is used.
694 Fix bad reference in UNIX comstack in function cs_addrstr.
696 Fix for compilation on AIX.
698 The generic front-end server (server/seshigh.c) now supports returning
699 Init diagnostics to the client in User-information-field, in
700 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
705 Allow any CQL relation (not just all,any,exact,scr).
707 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
708 that features the same UI.
710 Implemented command update0 in YAZ client which is equivalent to
711 update but uses old of Ext Update ASN.1.
713 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
714 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
715 Previously no OID was used for this info.
717 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
718 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
719 returns 'malformed search term' otherwise.
721 SortResponse member resultCount now set to NULL in sort handler of
724 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
727 Add three new utility functions for translating OIDs between various
728 formats -- symbolic name such as "Usmarc", minus-1-terminated int
729 arrays and dotted strings such as "1.2.840.10003.9.5.1":
730 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
731 char *oid_to_dotstring(const int *oid, char *oidbuf);
732 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
734 Reverted modifications for ES Update definition for z_IU0Update
735 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
736 is back to YAZ 2.0.2.
738 String value attributes for CCL parser.
740 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
741 which their FirstSearch server returns in Init responses, sometimes
742 carrying useful diagnostic information when Init fails. This has the
743 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
744 "z39.50/oclcui.asn", where its definition is somewhat different from
745 what OCLC document on their web-site, as required to interoperate with
748 Support for anonymous authentication in yaz-client. Use the command
751 * Fix the OID of the Index Data-local "admin" Extended Service from
752 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
753 the 1000, which indicates a locally-defined OID, was a mistake.
757 Fix CCL directive @case handling so that it affects string match for
758 both CCL keywords and qualifiers.
760 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
761 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
762 Decoder has been updated with ASN.1 changes as listed in
763 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
764 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
765 z_IUUpdate, remains unchanged.
767 ZOOM_record_get may now return a record in a specific character set.
768 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
769 "from" is the character set of record as returned by target. "to" is
770 the character set to be returned. If omitted, "to" is UTF-8.
772 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
774 New ODR utility, odr_getelement, which returns name of element for
775 which encoding/decoding failed.
777 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
778 in cases where a required element was omitted.
780 Bug fix: some MARC8 sequences were not converted.
782 New ZOOM option "step" which specifies number of records to be
783 retrieved in one chunk. Used in conjunction with "start" and "count".
785 SRW support for yaz-client. Use scheme http: to use it, e.g.
788 yaz-client no longer does (un)intelligent character set conversions
789 by default. Can be enabled with charset and marc_charset commands.
791 xmalloc trace fix for 64-bit systems such as DEC alpha.
793 Solaris 2.6 compile fix.
795 New function, cql_strerror() translates SRW error codes, as returned
796 by cql_transform_error(), into human-readable English strings. Used
797 in yaz-client diagnostics when appropriate.
799 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
800 converts it into a type-1 query which is sent to the server. This
801 makes CQL available for use with all Z-servers, as opposed to the tiny
802 minority that can handle CQL queries themselves.
806 New Debian package layout similar to the Redhat Package layout.
808 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
809 and search result respectively.
813 Redhat package is now several packages: libyaz (runtime libraries),
814 libyaz-devel (development and documentation, and yaz (utility programs).
815 Package spec file by Morten Bøgeskov.
817 New member 'schema' in struct bend_fetch_rr which the name of requested
818 schema (SRW/SRU) for record (or NULL if none was given). The fetch
819 handler MAY set this to reflect the schema of the returned record.
821 New member 'display_term' in struct scan_entry. GFS now sets member entries
822 and allocates scan entries to be filled by user scan handler. In previous
823 version, entries member was allocated by the scan handler. That still works,
824 but the GFS will ignore member display_term - assuming it was NOT set by
825 the handler. The fact that the GFS now allocates the entries both allows
826 for new members and makes a scan handler easier to write.
828 Fix CQL lex buffer overflow.
830 SRW/SRU recordPacking. For SRW default recordPacking is string. For
831 SRU default recordPacking is string.
833 SRU protocol support for frontend server.
835 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
837 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
839 Added scan for the ZOOM shell (zoomsh).
843 * String Identifers for Schemas (Amendment 5).
844 http://lcweb.loc.gov/z3950/agency/amend/am5.html
845 Old definition for schema
846 Odr_oid *schema; /* OPT */
851 Z_InternationalString *uri;
852 #define Z_Schema_oid 1
853 #define Z_Schema_uri 2
856 * resultCount parameter to Sort Response (Amendment 1).
857 http://lcweb.loc.gov/z3950/agency/amend/am1.html
859 Support for SRW 1.0 over HTTP. This is an optional feature and
860 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
863 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
864 on the same port. SRW SearchRetrieveRequests are mapped
865 to bend_init,bend_search,bend_fetch,bend_close.
867 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
869 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
870 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
872 ZOOM connections are SRW based if schem http is used for hostname
873 in connect, e.g. z = ZOOM_connection_new("http://myserver");
874 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
876 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
877 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
878 distance=n, order=true/false, relation=le, prox unit=word. If
879 n is omitted, distance 1 is used.
881 Fixed problem with C compiler include path in wrong order.
883 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
884 on Solaris. Patch from Ko van der Sloot.
886 New MARC decode API. All new functions operate on a yaz_marc_t
887 handle. The most important new functions are: yaz_marc_create,
888 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
889 decode and destroy respectively. Decoder can produce formats
890 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
891 include/yaz/marcdisp.h.
893 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
894 to UTF-8, UCS-32, wchar_t or Latin-1.
896 * Prototypes for yaz_iconv_-functions moved to separate header
897 include/yaz/yaz-iconv.h.
899 Make a few private functions 'static' in unix.c. This prevents
900 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
902 For ZOOM connection, the options targetImplementation{Id,Name,Version}
903 are set when Init Response is received.
905 New function ZOOM_connection_error_x similar to ZOOM_connection_error
906 but returns diagnostic set as well.
908 New function yaz_strerror which is a portable wrapper for
909 strerror/strerror_r/GetLastMessage.
911 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
912 is returned for MARC. If type is "oai", then OAI MARC is returned.
914 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
919 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
921 Fix bad race conditions on SIGTERM and terminate gracefully in
924 Move retrieval (data1) module to Zebra since nobody seems to be
927 Add GRS-1 render for ZOOM using same format as yaz-client.
931 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
933 Fix broken ESpec handling in data1 module.
935 SGML reader parses comments and makes them part of the data1 tree.
937 Added several type casts so that YAZ compiles as C++ code.
939 ZOOM didn't handle PDU encoding failures properly.
941 Added more Bib-1 diagnostics (approved extensions).
943 GNU configure: better check for iconv.
945 More portable use of accept, getpeername. Check for socklen_t. Use
946 int/size_t if socklen_t is not defined.
950 PQF parser rejects bad queries - including those with extra
951 characters in them. PQF parser used to silently ignore that.
952 Cleaner API for PQF added, which allows you to get detailed
953 error information for bad queries (see yaz/pquery.h).
955 Fixed bug in ZOOM_record_get for type "database".
957 Implemented mini iconv library supporting conversions between
958 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
960 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
964 Fixed ZOOM C record cache so that preferredRecordSyntax and
965 elementSetName is used to check for already fetched records.
969 Added three members in bend_initrequest structure to facilitate
970 character set negotiation.
972 Fixed a bug in frontend server that could cause indefinite
973 loops under rare conditions.
975 Revised character set utilities (charneg.h) so that encoding
976 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
978 For PQF, directive @term <type> sets term type for Scan/Search.
979 Here <type> is general, string, numeric, null. The term type
980 is inherited - just like @attr.
982 New call odr_set_charset that sets character set conversion for
983 international-strings on a ODR stream. Prototype is:
984 int odr_set_charset(ODR o, const char *to, const char *from);
985 The InternationalString is still represented as C string in YAZ
986 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
987 won't). On the protocol level, you can use any encoding.
989 Support for UNIX sockets in ZOOM.
991 Solaris recv sometimes returns errno == ENOENT. It is treated as
992 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
994 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
995 both client and server. Code by Morten Bøgeskov.
999 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1000 that they can be used directly from Visual Basic. You must recompile
1001 your windows APP if you're using ZOOM.
1003 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1004 Commands "lang" and "charset" sets language and character set respectively.
1005 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1006 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1008 Attributes from multiple CCL fields may be OR'ed rather than merged
1009 using directive "@field or". Fields are still merged by default -
1010 equivalent to "@field merge".
1012 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1015 Fixed bug in zget for parameter ExtendedServicesResponse.
1019 --- 1.8.6 2002/03/25
1021 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1023 Client displays USR.1:SearchResult-1 (hits per term).
1025 Additional Search Info for search in Generic Frontend Server.
1027 Fixed CCL parsing of "field=s".
1029 WIN32 installer - using the excellent NSIS software from nullsoft.
1031 Fixed CCL parsing of "field = - <number>".
1033 Added function yaz_marc_decode that decodes MARC for line mode
1034 display or XML (similar to that used by JZKit).
1036 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1037 Z39.50. But ISO/ILL was, however.
1039 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1040 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1042 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1043 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1045 --- 1.8.5 2002/02/03
1047 New YAZ client features: Command completion and new commands:
1048 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1049 Code provided by Jacob Poulsen.
1051 New call oid_trav, that visits all registered OIDs via callback.
1053 Function ZOOM_record_get now returns const char pointer rather than
1054 void pointer. It saves a lot of type casts.
1056 For YAZ client, command "auth" now allows you to set authentication
1057 in IdPass style. It is enabled when three tokens are given - order
1058 is user, group and password.
1060 Fix memory leaks in MARC record handling for ZOOM.
1062 New option for YAZ client, -k <kilobytes> that sets
1063 maximum record size. Similar to -k option for generic frontend
1064 server and yaz-ztest.
1066 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1068 Prefix query parser reports "fail" when bad attribute set is given.
1070 Fix in MARC decoder. Proximity logging. Fix for attribute set
1071 in scan handler for server. Patches by Shigeru Ishida.
1073 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1076 Configure option --with-openssl=<dir> now works when a directory is
1077 specified. Patch provided by Morten Bøgeskov.
1079 New option for YAZ client, -u <auth>, that sets authentication.
1081 ZOOM fix: error information was sometimes "missing", since error
1082 was cleared/reset too when it shouldn't.
1084 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1086 --- 1.8.4 2002/01/04
1088 Scan for ZOOM API. New object ZOOM_scanset. New functions
1089 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1090 ZOOM_scanset_destroy.
1092 New ZOOM function, ZOOM_connection_last_event, that returns type
1093 of last event (such as "receive data", "send data", "apdu received",
1096 New ZOOM option, schema, that specifies schema for retrieval.
1098 New CCL feature. Qualifiers can be aliases for one or more
1099 other qualifiers (if more than one is given, OR is used).
1101 ZOOM uses named result sets if target supports it.
1103 Two new YAZ client commands: . (dot, which sources a script of YAZ
1104 client commands), and ! (to execute shell command.). Implemented
1107 Working on Debian packages.
1109 --- 1.8.3 2001/11/19
1111 YAZ client enables named result sets only if target supports it.
1113 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1115 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1116 with key="host" to get same result.
1118 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1119 Function Z3950_resultset_record(s) returns references to records
1120 "owned" by resultset. To become owner use Z3950_record_clone.
1122 Function z_ext_record handles Extended Services. Thanks to
1125 --- 1.8.2 2001/11/12
1127 CCL Parser fix: ignore token comma when dealing with and-lists.
1129 Documentation updates for COMSTACK.
1131 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1132 Changed prototype Z3950_records. For some functions, int parameters
1133 were changed to size_t.
1135 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1138 New MARC decode/display function, marc_display_exl, which properly rejects
1139 non-ISO2709 records. YAZ client uses it.
1141 --- 1.8.1 2001/10/29
1143 Fix bug: local attribute set wasn't set correctly in PQF strings.
1147 * Old Z39.50 codecs no longer supported.
1149 Added ZOOM C binding. See http://zoom.z3950.org/
1151 Renamed states for COMSTACKs to avoid confusion with events.
1153 Implemented cs_look and proper cs_rcvconnect.
1155 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1157 Configure detects POSIX threads on OpenBSD.
1159 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1160 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1162 When error is returned from present handler, non-surrogate diagnostic
1163 is returned in present response (and fetch handler is no longer called).
1165 * Minor adjustments to pquery parser (PQF). Token characters may be
1166 escaped by using backslash (C-style).
1168 PQF parser allows string attribute values to be specified. For @attr,
1169 non-numeric characters after the equal-sign are treated as strings
1170 (e.g. @attr 9=title).
1172 CCL trunction character may be defined (@truncation in file)
1174 * function zget_ExtendedServicesRequest sets waitAction to
1175 waitIfPossible (was wait).
1177 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1180 CCL operator names may be set in field definition files (CCL_bibset).
1181 See ccl/bib1 for an example.
1183 Fixes in ASN.1 compiler for C++ compatibility.
1185 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1186 and "op_or" to avoid conflict with C++.
1188 Fixed problem with GNU readline detection on Redhat 7.0.
1190 Added step-size for Scan backend handler.
1192 Fixed bug that made the frontend server crash when no attribute
1193 set was specified for scan.
1195 Front-end server automatically switches to original working directory
1196 when installed as an NT service. Previously -w had to be specified to
1199 Added extended attributes for retrieval module (data1), so that data1
1200 records carry d1_readXML/SGML attributes. d1_read also supports
1201 null-data rules ( <tag/>)
1203 On UNIX when POSIX threads are available, a separate library libyazthread
1204 is created. Programmers should link with that library and the yaz library
1205 when using threads. The reason for the split was that some applications
1206 on Linux, such as Apache, doesn't work well when using shared objects that
1209 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1210 (or any frontend server) in SSL mode by specifying ssl: followed by
1211 address. Only tested on UNIX.
1213 Added feature for CCL module. Virtual structure s=al or s=ol generates
1214 and-list and or-list respectively instead of phrase search.
1218 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1219 log_mask_str. This was done to avoid name conflicts with other libraries
1220 (such as other PHP extensions).
1222 Added raw OID member for preferred record syntax (request_format_raw)
1223 and returned record syntax (output_format_raw) for backend fetch method.
1225 Config file yaz-config now accepts options so that it returns specific
1226 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1228 Shared library support for UNIX using GNU libtool.
1230 * Modified backend interface. Request/Response struct's replaced by
1231 one read/write C struct. For example bend_fetchrequest and
1232 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1233 Every handler - even search has to be registered in bend_init
1234 handler. This means that the YAZ library no longer refers to
1235 external functions and it makes it possible to make the whole
1236 thing a single DLL/SO.
1238 Added Segment handler for backend server.
1240 Added Zmbol/Zebra administrative functions to YAZ client.
1242 Threaded frontend server on UNIX (when POSIX Threads are available).
1243 Starting the server with option -T enables multi-threading.
1247 Added configure option --enable-comp/disable-comp to control use
1248 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1249 located in sub directory asn.
1251 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1252 in ${exec_prefix}/bin along with the other programs yaz-client and
1255 GNU automake used to maintain makefiles.
1257 Added several OID's.
1259 Changed retrieval module so that we can load records with no abstract
1260 syntax defined. Tagpaths in these records are fully composed of string
1263 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1267 On UNIX, the generated makefile now supports a proper 'make install'.
1268 The prefix can be set via GNU configure to set the install location
1269 (default is /usr/local).
1271 * YAZ programs client and ztest were renamed to yaz-client and
1272 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1273 locations, such as /usr/bin,/usr/local/bin,etc.
1275 * YAZ Header files were moved from include to include/yaz. YAZ Header
1276 files are referred to as include <yaz/log.h> rather than <log.h>.
1277 The YAZ include path (-I ..) is therefore the same as before. Programmers
1278 should update their #include statements or use -Ipath/include/yaz
1279 instead. The main motivation for doing this change is that YAZ header files
1280 can be installed in "standard" locations /usr/include,/usr/local/include
1281 without introducing conflicts, since ALL YAZ header files are stored
1282 in subdirectory yaz (under /usr/include for example).
1284 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1285 rather than project/workspace files. We switched because project files
1286 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1289 Changed name of logging function, logf, to yaz_log, to prevent name
1290 clash with some math-log functions. The YAZ header log.h defines logf
1291 to yaz_log (#define) so there should be no incompatibilities by this
1294 Added bend_start/bend_stop handlers for server. These handler are
1295 called on start/stop of server. For windows they are called whenever
1296 a service is started/stopped.
1298 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1299 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1300 in util/yc.tcl. The auto-generated C code structures are, in a few
1301 cases, incompatible with the old decoders. There are differences in the
1302 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1303 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1304 The preprocessor variable ASN_COMPILED is defined when the compiled
1305 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1306 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1307 wish to use the old encoders/decoders you can specify --disable-yc
1310 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1311 version so that it supports both new - and old version of DB Update
1313 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1314 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1315 change. The name parameter can be set to 0 in which no name is specified
1316 for the construction. The macros odr_implicit and odr_explicit sets name
1317 parameter to zero for the construction involved. New macros
1318 odr_implicit_tag and odr_explicit_tag are similar to the others,
1319 except that a name parameter is added. For programmers' that don't use
1320 ODR they probably only need to change the call to z_APDU and z_External.
1322 Added access control facility by interfacing the TCP wrapper library.
1323 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1324 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1325 name of the daemon and enables the access control as specified in
1326 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1328 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1329 den Dool <H.M.vdnDool@kub.nl>.
1331 Added reference ID parameter to most functions in server API - refer
1332 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1334 Changed name of ccl library to libccl.a (was ccl.a).
1336 Fixed bug in decoder for Explain (Category TargetInfo).
1338 Added support for GNU readline in client. Thanks to Jacob Poulsen
1339 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1341 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1342 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1343 IMPLEMENTATION! This change was made to the development version before
1344 the ZIG decided to retract the amendment. If any users MUST be
1345 compatible with the original Update definition, PLEASE CONTACT US, and
1346 we will include a separate definition corresponding to the old Update
1347 ES. Note that because of the change to the ASN.1 of the
1348 TaskPackageRecordStructure we cannot define a single structure that
1349 will support both versions.
1351 * Added const modifier to buffer parameter for some ODR/BER encoding
1352 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1353 completeWAIS, odr_dumpBER.
1355 Fixed bug in client.c which caused a crash when a scanResponse didn't
1356 contain positionOfTerm.
1358 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1359 * will cause an error in a client if a non-YAZ target sends both a
1360 * list of Scan entries and non-surrogate diagnostics.
1362 Retrieval module enhancements. Tag sets may be typed in the reference
1363 to it. From the .abs-file the "tagset" directive takes a third optional
1364 integer type for the tag set referenced. From a .tag-file the "include"
1365 directive takes a third optional type as well. The old "type" directive
1366 in the tag set itself is still recognized but acts as the default type
1369 Backend interface change. Individual Scan terms returned from bend_scan
1370 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1371 in include/backend.h.
1373 Retrieval module enhancements. Multiple tag sets and attribute sets may
1374 be specified in abstract syntax specs. Revised the error/warning for
1375 logging messages reported by the retrieval module when reading the
1378 Object Identifier system (oid_..) changed. The API is backwards
1379 compatible but the oid-routines now allocates new OID's when needed.
1380 Raw OID's may be specified in oid_getvalbyname.
1382 YAZ now uses GNU configure to generate Makefile(s).
1384 * Minor changes in some of the member names of DeleteResultSetRequest and
1385 DeleteResultSetResponse. See include/proto.h.
1387 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1388 and added member 'languages' in TargetInfo (which was missing).
1390 Changed the way attribute sets are handled in the retrieval
1391 module. These are now cached, just like the abstract syntaxes
1394 Changed YAZ so that it links with compiled ASN.1.
1396 Added Explain-schema definitions and mapping routines. The following
1397 Explain categories have been implemented: AttributeDetails,
1398 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1400 Fixed minor bug in Windows version of Server Library.
1402 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1404 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1406 Added EXTERNAL: UNIverse Resource Report (non-standard).
1408 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1409 ENUMERATED and SET OF.
1411 * Added 'const' to some of the char pointer arguments for the
1412 functions, data1_read_node, data1_getelementbytagname,
1413 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1416 Fixed bug in data1_insert_taggeddata - the last_child member of
1417 parent wasn't initialised.
1419 * Changed data1_read_record and data1_read_node so that the supplied
1420 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1421 doesn't refer to any parts of the "SGML"-buffer.
1423 Fixed bug in server library (Windows version of statserv_remove).
1425 * Changed code so that it compiles as C++. The type definition
1426 of Odr_fun which is a member of Odr_arm was changed. The result is,
1427 that an explicit typecast is needed for the fun pointer when
1428 using Odr_arm - as in:
1429 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1431 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1433 Implemented the new structured date and time definition as approved
1434 by the ZIG. Added schemaId element to the specificTag in Espec-1
1435 (also approved at the last ZIG). Thanks to RVDM.
1437 Added some Object identifiers (RVDM).
1439 Changed the Update Extended Service (RVDM).
1441 Added command "refid" to client which specifies referenceId for
1442 the following requests.
1444 Implemented extended service handling for server. See ztest.c
1445 for an example as well as backend.h. New handlers are registerd
1446 in the Init handler.
1448 * Changed interface for sort in server.
1450 Added new members to statserv_options_block. It allows a server
1451 to read options from another source than just the command line. Thanks
1452 to Charles Woodfield.
1454 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1455 renamed to zboolean. Some C++ compilers complained about the name.
1457 Minor changes to gils.abs. Added index 's' (sort) on title
1458 and date/time-last-modified.
1460 --- 1.4pl2 1998/1/30
1462 Fixed bug in server library regarding inetd mode (-i). This bug
1463 was introduced by release 1.4.
1465 --- 1.4pl1 1998/1/29
1467 Added sort facility in client and backend server interface.
1469 Fixed problem with dependencies in Makefile(s).
1471 Fixed bugs for encoders/decoders of extended services and
1474 Implemented sub-tree feature for schemas. Sub-trees are
1475 referenced in *.abs-files. See explain.abs for an example
1476 of the use of this feature.
1478 Modified bib1.att; local attributes for ANY didn't include
1479 ANY itself (only affects use of the retrieval module).
1481 Fixed bug in plain SGML reader in function data1_read_node:
1482 tags with prefix "var" was incorrectly interpreted as variants.
1484 Added feature "sub-schemas" to enable references to - and definitions
1485 of - group of elements.
1487 * Removed member parent from type data1_element (in data1.h).
1489 Implemented function odr_nullval() that returns the value of
1492 * Removed member num_children from data1_node (in data1.h).
1494 Made NT service interface part of the server library. The
1495 function statserv_main uses the NT service when required and
1496 calls the statserv_start / statserv_close routines.
1498 Routine zget_SearchRequest and zget_PresentRequest fills
1499 resultSetName/Id member with "default" instead of "Default".
1501 Fixed memory leak in server. Request queue member wasn't freed.
1503 Fixed nmem_exit so that memory is freed.
1507 Revised the CCL parser utility to be thread safe.
1509 Added function, oid_ent_to_oid, to replace the function
1510 oid_getoidbyent, which is not thread safe.
1512 * Added nmem_init and nmem_exit to initialize and release
1513 NMEM resources. Function nmem_init should be called once in the
1514 initial thread before NMEM/ODR is used. statserv.c and client.c
1515 have been changed accordingly. The change was necessary to make
1516 NMEM thread safe. The NMEM memory pool is shared amongst threads
1517 in a process. Unix-based applications will still work fine without
1520 Added NT Services interface for the the Z39.50 (statserv) Server.
1521 Refer to the ztest.c source on the usage.
1523 Windows 95/NT port using MSVC5.0. Project files are included in the
1526 * Defined new 'global' handle for the retrieval (data1) system. The
1527 new handled, data1_handle, describes the state of the data1 system.
1528 This handle is passed as first argument to virtually all
1529 data1 related routines. The functions data1_create and data1_destroy
1530 creates and destroys a data1 handle respectively.
1532 Added ODR encode stream member to all backend request structures
1533 init, search, scan etc. This stream should be used to allocate all
1534 memory used for the response when thread safe operation is needed.
1536 Changed the comstack utility, cs_addstr, to be thread safe. The
1537 returned hostname string returned by the function is now part the
1540 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1541 function. The cs_straddr takes a COMSTACK handle as argument, so this
1542 function must be used after cs_create and before bind/connect.
1543 This function is thread safe.
1545 Moved test server to 'ztest' directory - generic server code still
1546 in 'server' directory.
1548 Made prefix query (pquery.c) utility thread safe.
1550 Added new function modifier YAZ_EXPORT to 'export' public DLL
1551 functions when using windows (see include/yconfig.h).
1553 Added definitions to the OID database (util/oid.c) (RVDM).
1555 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1557 Added call to ccl_rpn_delete in client program.
1559 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1560 release of RPN structure.
1562 Added support for C++, headers uses extern "C" for public definitions.
1563 With input from RVDM.
1565 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1566 Thanks to Ronald van der Meer (RVDM).
1568 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1570 Added support for private extensions to the OID database
1571 (oid_setprivateoids()). Thanks to RVDM.
1573 Added optional, physical ANY (key replication)
1575 Fixed null-reference problem in GRS-1 output filter.
1577 Proximity operator added to Prefix Query Format (PQF).
1579 In test client command "base" accepts multiple databases.
1581 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1585 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1587 Smallish bug-fixes in the new encoders/decoders (explain).
1589 Bug fixed in DeleteRequest.
1591 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1593 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1595 Added SOIF syntax (using private OID for now) to retrieval module and client.
1597 Added Update extended service.
1599 Added SearchResult-1 additional info structure.
1601 Added optional CCL (ISO8777) interpreter as separate module. Available
1604 --- 1.2 1996/6/10 (1st anniversary release)
1606 Added Summary record syntax. Lightly tested.
1608 Added OPAC record syntax. Untested.
1610 Added ResourceReport service encoders/decoders. Untested.
1612 Fixed bug in z_Unit - wrong tagging on unitSystem.
1614 Fixed bug in the DiagRecs decoder.
1616 Added options for max PDU size and session timeout to frontend-server.
1618 Added documentation of query-language parsers and other supporting utilities.
1620 [frontend-server] Added Attribute set to the bend_scanrequest API.
1622 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1623 surrogate diagnostics were generated.
1625 [retrieval] Allow multiple local values for attribute.
1627 [retrieval] Allow multiple attributes per element in .abs files. index type.
1629 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1631 --- 1.1pl2 1996/4/10
1633 Minor changes, mostly specific to Zebra's requirements (retrieval)
1637 Repaired bug in frontend server when running multiple listening
1638 endpoints in dynamic mode.
1640 z_External() now won't break if a known, ASN.1 value comes encapsulated
1641 in an octet-string. The value will pass through unmodified in an Odr_oct.
1643 Added a bit of code to the demo client to decode & display
1644 ASN.1-structured records represented in the octet-aligned branch of
1645 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1647 Added z_ext_getentbyref() to the ASN module. Doc updated.
1649 * Completed the SCAN definition in the ASN module. This may break SCAN
1650 code based on older YAZ-versions at compile-time. The fix is easy -
1653 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1654 under the SCAN definition. Remember to initialize this, server-people.
1656 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1657 that this does not extend to ODR and ASN.
1659 Comstack allows insertion of established socket (primarily for
1660 inetd-operation of servers). Doc updated.
1662 Front-end server can now start from the inetd in TCP mode. Doc
1665 --- 1.0pl4 1996/1/24
1669 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1670 the rank and record number.
1672 Adjustments to the frontend server.
1674 Fixed diagnostic BER dumper. It ignored the file argument.
1678 Various changes to retrieval module.
1680 Changed the union discriminators of the protocol files from enums to
1681 ints paired with #defines.
1683 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1686 *Changed operator in the RPN structure to 'roperator', again to avoid a
1689 Fixed problems in Explain decoders/encoders.
1691 --- 1.0pl2 1995/12/6
1693 Memory bug in log module fixed.
1695 --- 1.0pl1 1995/12/5
1697 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1699 Bug in Explain DatabaseInfo module fixed.
1701 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1705 The shift to v1.0 signals that we now consider the *core* functionality
1706 of YAZ reasonably stable (the core being more or less equivalent to
1707 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1708 tested (Explain not at all - though that will happen soonish).
1710 Minor changes to code to support Windows port.
1712 Various minor changes after we're getting to use GRS-1 & co. more.
1714 Added Espec-1 format.
1716 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1717 of the protocol and it cannot be selected when encoding (maps into 'string'
1718 when decoding). Needed to talk to some servers.
1720 Demo client can request simple element set names.
1722 Added Diagnostic Format encoders/decoders.
1724 Added simple Close handling to frontend server (no hooks for resource
1725 reporting yet), and demonstration client.
1727 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1729 --- 1.0b3 1995/08/24
1731 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1732 handled incorrectly when records were requested in the searchResponse. This
1733 will only affect you if you use the frontend-server.
1735 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1736 Test-client will ask for and print GRS1. Ztest will return dummy records
1739 Added Explain encoders/decoders to the service-level API. Untested.
1741 Added Extended Services: Item Order encoders and decoders to the Service-
1742 level API. Untested. We could use a recent copy of the pertinent bits
1743 of the ILL protocol to add those bits.
1745 Added diagnostic format 1 encoders/decoders to the service-level API.
1748 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1749 odr_cons.c, which causes a more correct output.
1751 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1752 was always set to 0 when no records were requested in the searchRequest.
1754 * Added better external-handling. This shouldn't harm old code that
1755 *encodes* externals. It can break code that looks for a
1756 'single-ASN1-type' representation, since those types that are known
1757 are now decoded immediately. Look at the SUTRS sample code in
1758 seshigh.c and client.c. Documentation updated.
1760 Handling of structured records in bend_fetchresponse. Length -1 marks
1761 structured record, type is deduced from format field.
1763 --- 1.0b2 1995/06/27
1764 Fairly quick maintenance release to add SUTRS support.
1766 Fixed handling of SUTRS records in the demonstration client.
1768 * Added format field to the bend_fetchrequest and bend_fetchresponce
1769 structures of the backend API (frontend server). When the record is
1770 returned, the value of the format field is mapped to an OID. The
1771 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1772 of the record. The special value VAL_NONE in the bend_request means
1773 that no specific format was requested by the client. Documentation
1774 updated accordingly. Test server (ztest) will return a fixed dummy
1775 SUTRS record if your client requests SUTRS.
1777 Documentation updated accordingly.
1779 You can now set external libraries and RANLIB support in the top-level
1783 First public release.
