1 Allow missingValueAction to be specified for the sortspec string -
2 function yaz_sort_spec. By default, the missing value action is null.
3 Use ! to specify "abort". Use = followed by stringvalue to specify default
6 Ensured that Present-handler (if defined) is called in GFS before any call to
7 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
8 searchRetrieve requests.
10 Documentation for YAZ is now based on the Docbook XML/XSLT using
11 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
12 is no longer depending on jade/openjade or docbook-to-man scripts.
13 PDF is no longer part of the distribution - but can optionally be
14 made using DSSSL/jadetex or FOP.
16 Added retrieval handling support in Generic Frontend Server to support
17 conversion between MARC/XML as well as XSLTtransforms. See
18 etc/yazgfs.xml for an example.
20 Added Authentication support to Generic Frontend Server in SRU
21 mode. Authentication using HTTP Basic is supported, as is the use
22 of 'x-username' and 'x-password' parameters in the request itself.
24 Added support for a new character set MARC8s identical to MARC8 except
25 that it converts combined characters to single Unicode characters in the
26 Latin-1 range (when possible).
30 ASN.1 compiler 0.4: generates brief Doxygen file header for
31 generated .h/.c files.
33 Utility yaz_iconv now supports conversion to MARC-8.
35 New facilities for the MARC module. The reading - and writing of
36 content are separate methods for the yaz_marc_t handle. The following
37 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
38 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
39 format). Write functions have prefix yaz_marc_write_.. The existing
40 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
41 available. Removed support for OAI-MARC and simplexml (not the
44 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
45 to be returned for this connection.
49 Allow multiple languages and charsets to be specified with
50 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
51 negcharset iso-8859-1,utf-8
53 Translation of proximity nodes from CQL into PQF now works.
55 Moved to automake 1.8, 1.9.
57 Added function yaz_log_set_handler which allows a log handler to be
58 installed. This handler will be called for all log messages. Output
59 to file is also produced; but that can be disabled by passing NULL
60 fname to yaz_log_init_file.
62 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
64 For SRW (including GFS), accept application/soap+xml as content-type
67 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
68 produces NO stylesheet reference even if a default stylesheet is specified
73 Updated Windows package to include yazd.dll + yazd.lib for the
74 Development component.
76 If the environment variable YAZ_LOG is set, then it is used as a
77 string indicating the default level of logging to use if not
78 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
79 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
80 used as before. So, for example, to omit warnings from YAZ logging,
83 cql_transform() now map structure and other attributes before indexes,
84 so that index-specific structures and other attributes can override
85 defaults. So now a combination of mapping specifications such as:
87 index.dc.date = 1=date-modified 4=5
90 cql_transform() now also respects the "always" mapping specification,
91 which establishes an initial set of attributes to be used for all
92 terms except where overridden by more specific attributes associated
93 with the index, relation or modifier.
95 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
96 which mode to use; one of "post", "get" or "soap" (SRW, default).
98 Fixes for yaz_iconv routines: changed trie-based character set conversions
99 to use only non-negative values for bit fields due to Sun's C compiler not
100 supporting negative values.
102 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
103 sequences where not read correctly. Fix by Rustam Usmanov.
105 Updated win/makefile to use options, settings which makes things
106 compile with VS C 2005.
108 --- 2.1.12 2006/02/01
110 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
112 In ZOOM socket code, use select instead of poll on MacOSX.
114 ZOOM-C now support client-side compilation of CQL into RPN that is
115 sent to the server, enabling CQL to be used against all Z39.50
116 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
117 ZOOM_query object, and submit it using ZOOM_connection_search().
118 The CQL-to-RPN translation uses a configuration file, the name of
119 which must be specified in the Connection's "cqlfile" option.
121 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
122 function, which takes as its start-term parameter a ZOOM_query object
123 (which may have had either CQL or RPN set into it).
126 --- 2.1.10 2005/11/29
128 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
129 GFS to support this as well. Backend handler, bend_srw_update, does the
130 update work. Code contributed by Ko van der Sloot.
132 Allow retrieval of Search Result-1 information in ZOOM by the use of
133 options that are attached to a result set. ZOOM documentation updated
136 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
137 UTF-8 conversion. Patch by Raj Patel.
139 Added option -m to GFS to control formatting of timestamps in log file.
141 Added 'exit' as synonym for 'quit' in yaz-client
143 Added support for specifying SRW resultSetId + resultSetIdleTime in a
144 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
145 for the new members. Patch by Ko van der Sloot.
147 Added support for SRU POST. It is supported for content-type
148 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
150 Do not build the separate Multi-threaded (MT) library libyazthread.la.
151 Instead make the library libyaz.la multi-threaded. Threading as a whole
152 can still be disabled by configure option --disable-threads. Previosly,
153 with older GLIBCs there were problems with MT libs under Apache. This
154 has now been fixed a long time ago.
156 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
159 CQL module modified to be case insensitive for relations/indexes/operations.
161 Fixed bug in CQL transform code: incorrect value relationModifieder
164 Added 'show all' command for yaz-client which retrieves all results
167 Added new yaz-client, xmles, which takes a (private) OID and
168 a document to be sent as an extended service request.
170 Describe new yaz-client commands wait_response and set_auto_wait.
172 Increase TCP/IP listener backlog from 3 (which I am guessing was
173 copied from the SunOS manual entry way back when) so SOMAXCONN, so
174 that the socket will queue as many incoming connections as it's able
175 to handle ongoing connections. In other words, it will never now
176 refuse a connection that it would be able to handle merely because
177 it's not got around to accepting() enough of the pending connections
178 yet. This is the behaviour anyway under Linux, where the listen()
179 argument is ignored; but not under BSD and on systems such as
180 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
181 YAZ-based servers should now be uniform across operating systems in
184 yaz-marcdump uses 64-bit file access on some systems. This is enabled
185 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
186 This allows yaz-marcdump to read large MARC batches (>2 GB).
188 Modified all YAZ source files - except the source which is auto-generated
189 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
192 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
193 corresponding to the existing *_setl() function. These allow option
194 values containing arbitrary valuues.
196 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
197 ZOOM_resultset_sort() in new applications. Its behaviour is identical
198 except that it returns an indicator of whether or not the sort
199 criterion was accepted (0 for OK, -1 for invalid).
203 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
204 MARC output rather than returning "new" buffer.
206 yaz-client warns about unknown init options.
208 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
212 Added support for SRW sort in Generic Frontend Server. Patch
213 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
214 sortKeys - or NULL if none is provided.
216 Fixed bug #307: It was impossible to specify indefinite/no timeout
217 for ZOOM_event. Special timeout value -1 now means indefinite timeout
220 Added support for multiple languages and charsets to be specified in
221 ZOOM. Each charset/language is separated by a blank. If negotiation is
222 in effect in init-response, Option
223 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
224 Code based on patch by Vasiliy Osadchuk.
226 Fixed bug #306: infinite recursion that occurred when calling
227 yaz_log_level_init as the first call (before other log level or
230 Fixed bug in scan handling in front end server: if preferred-Position-In-
231 Response was non-present, a NULL pointer referece was performed.
235 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
236 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
237 now defined for all those error codes. So instead of putting 109 in
238 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
239 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
241 Modified the yaz-marcdump utility to skip garbage bytes between MARC
244 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
246 Program yaz-client now exits and produces an error message if multiple
247 Z39.50 servers are specified on the command line (none or one allowed
250 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
255 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
257 Fixed bug #272: Preserve spacing for CCL terms.
261 Added support for virtual hosts and multiple backend servers for
262 the YAZ frontend server. The configution is XML based and
263 support specificition of CQL to RPN mappings and explain information.
264 See section "Virtual Hosts" in the YAZ manual.
266 Extended OPAC display utility. OPAC display utility renders
267 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
268 to supplement yaz_marc_decode_wrbuf.
270 Fixed a bug in MARC decoder that could caused it to crash for some
271 invalid MARC records. More diagnostics and warnings where added in
272 XML output (warnings, etc are stored in comments).
274 --- 2.0.34 2005/02/08
276 Fixes for UNIX domain sockets. Bug #261.
278 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
280 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
281 Added yaz_marc_subfield_str which defines subfield lead string which is
282 used in YAZ_MARC_LINE format. Default string is blank+$. Added
283 yaz_marc_endline_str which defines end of fields string used in
284 YAZ_MARC_LINE format. Default string is newline.
286 Experimental support for MarcXChange. This format can be produced
287 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
288 http://www.bs.dk/standards/MarcXchange.xsd
290 Added yaz-client commands scansize that sets maximum number of
291 entries to be returned by scan.
293 --- 2.0.32 2005/01/11
295 Added support for SRW scan in yaz-client and Generic Frontend Server.
297 * Added whereInList member to SRW Scan Term.
299 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
301 Fixed NMEM system to return aligned blocks on the smallest boundaries
302 that are suitably aligned for all possible types on the particular
303 architecture YAZ is being built for.
305 --- 2.0.30 2005/01/04
307 Fixed numerious warnings that was issued with newer versions of GCC.
309 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
310 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
313 Make YAZ Generic Frontend Server slightly faster.
315 Enhance (and reduce) logging for Generic Frontend Server.
317 Revert YAZ log system so that it flushes every write operation
318 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
320 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
321 instead of LOG_, due to name clash with syslog(3). LOG_ are still
322 present. New applications should define YAZ_USE_NEW_LOG=1 - this
323 will effectively disable old definitions.
325 --- 2.0.28 2004/11/09
327 Added yaz_log_time_format which specifies log format using
330 Added yaz_log_module_level which returns mask for a module. Value
331 is non-zero mask a if module is enabled; zero if disabled.
333 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
334 in include/yaz/cql.h.
336 Fixed bug #176: Dont throw diagnostics on empty SRU args.
338 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
340 Fixed bug #172: RPM builds does not enable SSL.
342 Doxyfile.in part of dist. Doxyfile generated by configure.
344 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
345 are given and the corresponding component does not exist.
347 Extend CCL documentation in YAZ reference. Describe r=r.
349 --- 2.0.26 2004/10/01
351 Fixed MARC->MARCXML conversion to properly deal with
352 fields, subfields, indicators having non-ASCII characters.
354 Fixed MARC->MARCXML conversion so that ASCII control characters
355 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
358 Added YAZ GFS support for conversion from Z39.50 surrogate
359 diagnostics to SRW surrogate diagnostics.
361 Bug fix: YAZ GFS did not return schema in explainResponse.
363 --- 2.0.25 2004/09/30
365 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
366 now converts recordSchema to elementSetName as well as schema URI.
368 Fixed bug in COMSTACK that prevented HTTP request packages from being
371 --- 2.0.24 2004/09/29
373 Added CCL facility r=r "range" which is similar to r=o "ordered" but
374 does not require white-space before and after the dash in a range, e.g.
375 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
378 Fixed a few AC_TRY_LINK configure tests that did not operate properly
379 due to new GCC removing "redundant" code.
381 Added yaz-client commands scanpos and scanstep that sets preferred
382 position and step-size for scan.
384 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
386 Added CCL utility ccl_qual_buf which parses one or more CCL
387 spec lines in a buffer.
389 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
390 of name and value - ignoring empty lines and comments.
392 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
394 Added odr_get_element_path which returns current element path for an
395 ODR handle. This utility is useful in error handling or user-defined
398 Added ODR_PRINT utility odr_set_stream which is is a more generic
399 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
400 to a write function and pointer to close function. The close function - if
401 non-NULL - will be called during odr_destroy.
403 Fixed bug in CCL parser where truncation char was not removed from
404 right side when truncation=both was in effect.
406 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
409 --- 2.0.23 2004/08/11
411 Fix buffer overrun in CQL parser when dealing with proximity (%).
413 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
414 to UTF-8/UCS conversion is now only based on codetables.xml.
416 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
418 --- 2.0.22 2004/08/06
420 Add support for more "commit changes" in ZOOM (uses Extended Services).
422 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
425 Yet another small fix for configure of SSL.
427 --- 2.0.21 2004/05/14
429 Fix SSL libs for configure when --with-openssl=DIR is given.
431 --- 2.0.20 2004/05/10
433 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
435 SSL comstack now uses yaz.pem certificate file on server side
436 by default. Certificate filename can be configured by calling
437 comstack function cs_set_ssl_certificate_file before cs_bind is used.
439 Fix bug regarding multiple calls to ZOOM_connection_connect.
441 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
443 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
444 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
446 ZOOM now allows inspection of X509 peer certificate for verification.
447 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
449 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
450 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
451 as "modular" but it simplifies things.
453 Added cs_get_peer_certificate to that returns peer X509 PEM.
455 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
456 NULL if SSL is unavailable.
458 Documentation about MARC decoding tools.
460 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
462 --- 2.0.19 2004/03/30
464 Rename CHANGELOG to NEWS to follow GNU style packing.
466 Fix bug with missing initialization of member in init_diagnostics.
467 This bug affects threaded version of GFS server.
469 --- 2.0.18 2004/03/20
471 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
474 Ensure zlib.dll is packed with Windows install.
476 --- 2.0.17 2004/03/17
478 Fix encoding of xsd:string to use text instead of CDATA.
480 Fix endless loop in CQL parser with unbalanced ".
482 Use a more compact way to store MARC-8 conversion tables.
484 --- 2.0.16 2004/03/16 Debian only
486 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
489 Update CQL parser to use new CQL 1.1 modifiers for booleans and
494 --- 2.0.15 2004/03/01
496 Another fix for decoding of XML packed records.
498 --- 2.0.14 2004/02/25
500 Fixes for Chunked encoding. White space not ignored after length spec.
502 Update NS and use default NS for SRW diagnostic elements.
504 --- 2.0.13 2004/02/23
506 Implement ZOOM_resultset_cache_reset which resets record cache.
508 Implement ZOOM_resultset_sort which sorts a result set.
510 Implement chunked HTTP transfer.
512 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
514 --- 2.0.12 2004/02/16
516 Added member 'schema' to bend_explain_rr structure so that backend
517 can specify explain record identifier. Defaults to Zeerex 2.0.
519 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
521 --- 2.0.11 2004/02/16
523 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
526 Added init command for yaz-client which sends "extra" init request.
528 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
529 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
531 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
533 Make ZOOM error code for "invalid query".
535 Fixed compilation for SSL which wasn't properly enabled for all platforms.
537 --- 2.0.10 2004/02/05
539 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
542 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
544 Added option -p <file> to make Generic Frontend Server to write PID file.
546 Added option -D to put Generic Frontend Server in background on its own.
548 Make ZOOM C recognize option "password". If unset, "pass" is used
549 (for backwards compatibility).
551 Fixed a bug in Generic Frontend Server that could make it crash if a
552 client sets characterSetNegotation bit, but didn't pass negotiation stuff
555 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
556 Must be issued before open, in order to be in effect.
558 --- 2.0.9-6 2004/01/12 Debian/Windows
560 Make the SRU server more picky WRT unknown params, etc.
562 Bug fix: ZOOM scan response didn't return displayTerm - when present.
564 New YAZ client command, options, that sets Z39.50 options.
566 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
567 options from a string of tokens (one token for each option bit).
569 Update SRW diagnostic code messages.
571 --- 2.0.9-5 2004/01/07 Debian/Windows
573 Handle user defined stylesheet for SRW/SRU.
575 --- 2.0.9-4 2004/01/06 Debian/Windows
577 Fix bug in decoding of Content-Length.
579 --- 2.0.9-3 2004/01/06 Debian/Windows
581 Fix a bug with decoding of XML packed records.
583 --- 2.0.9-2 2004/01/05 Debian only
585 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
587 Fix bug in SRW/SRU diagnostics decoding.
591 Fixed bug in Generic Frontend Server which could drop records exceeding
592 preferred message size. Reported and fixed by Irina Dijour.
594 Fixed calculation of package size for structured records in Generic
595 Frontend Server. Reported and fixed by Irina Dijour.
597 Fixed namespace for SRW/SRU diagnostics.
599 Fixed SEGV in yaz-client that occured for HTTP connection errors.
603 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
604 this version is incompatible with version 1.0 and older YAZ SRW/SRU
607 CQL changes to reflect recent changes to the specification:
608 * Documentation talks about context sets instead of index sets.
609 * Documentation talks about indexes instead of qualifiers.
610 * The CQL-to-PQF transformer's configuration file now uses
611 "index.set.name = <attributes>" instead of the old form
612 "qualifier.set.name = <attributes>". (Both forms are still
613 understood but the latter is deprecated.)
614 * CQL terms with no explicit index specified are now interpreted as
615 cql.serverChoice instead of srw.serverChoice (which of course
616 behaves exactly the same.)
620 MARC conversion can now generate ISO2709 output in another
621 character set. yaz-marcdump uses this facility if you invoke it
624 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
625 functions from there can be used from C++.
629 Frontend server now transfers memory from decoded packages to stream
632 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
633 references to show up.
635 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
636 the ZOOM Abstract API. The older names for the same options are still
637 also supported for the benefit of old applications.
639 ZOOM-C supports "implementationId" and "implementationVersion" options
640 to go along with "implementationName". These allow the user code to
641 specify identification strings to be sent to servers.
642 Add OID for the new ExtLite attribute set.
644 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
645 as requested/supplid by Ere Maijala <ere@atp.fi>
647 For generic frontend server, reverse the order of
648 "toolkit-supplied / application-supplied" strings sent as implementationId,
649 Name and Version. Also, remove the spaces around the slash. This brings
650 the GFS in line with the behaviour of ZOOM-C on the client side.
652 Add function ZOOM_scanset_display_term.
654 yaz-client shows scan displayTerm if present.
656 Utility yaz-iconv is now installed by default along with the man page
659 Extend configure check for OpenSSL to use pkg-config where available (such
662 Incorporate patch by Morten Bogeskov which allows a Unix file socket
663 server to specify uid/gid/mask for socket using the format
664 unix:[user=uid,][group=gid,][umask=mask,]file=path
665 If file= is omitted the existing format is assumed, e.g.
667 in which case the mask is 0666 (rw for everybody).
669 Major restructure of YAZ source. All source in libyaz is in src directory.
670 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
671 util (utility programs such as ASN.1 compiler, yaz-marcdump).
673 Added man page for utility yaz-marcdump (used to be called marcdump).
674 yaz-marcdump is installed by 'make install'.
676 Fixed a memory leak in Generic Frontend Server that occurred when decoding
677 of incoming package failed.
679 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
681 Change prototype of odr_perror: add const to message string.
683 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
685 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
686 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
687 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
688 DNS lookup. There should not be any compatibility problems with this
689 assuming that blocking=1 or 0 is used.
691 Fix bad reference in UNIX comstack in function cs_addrstr.
693 Fix for compilation on AIX.
695 The generic front-end server (server/seshigh.c) now supports returning
696 Init diagnostics to the client in User-information-field, in
697 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
702 Allow any CQL relation (not just all,any,exact,scr).
704 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
705 that features the same UI.
707 Implemented command update0 in YAZ client which is equivalent to
708 update but uses old of Ext Update ASN.1.
710 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
711 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
712 Previously no OID was used for this info.
714 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
715 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
716 returns 'malformed search term' otherwise.
718 SortResponse member resultCount now set to NULL in sort handler of
721 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
724 Add three new utility functions for translating OIDs between various
725 formats -- symbolic name such as "Usmarc", minus-1-terminated int
726 arrays and dotted strings such as "1.2.840.10003.9.5.1":
727 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
728 char *oid_to_dotstring(const int *oid, char *oidbuf);
729 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
731 Reverted modifications for ES Update definition for z_IU0Update
732 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
733 is back to YAZ 2.0.2.
735 String value attributes for CCL parser.
737 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
738 which their FirstSearch server returns in Init responses, sometimes
739 carrying useful diagnostic information when Init fails. This has the
740 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
741 "z39.50/oclcui.asn", where its definition is somewhat different from
742 what OCLC document on their web-site, as required to interoperate with
745 Support for anonymous authentication in yaz-client. Use the command
748 * Fix the OID of the Index Data-local "admin" Extended Service from
749 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
750 the 1000, which indicates a locally-defined OID, was a mistake.
754 Fix CCL directive @case handling so that it affects string match for
755 both CCL keywords and qualifiers.
757 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
758 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
759 Decoder has been updated with ASN.1 changes as listed in
760 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
761 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
762 z_IUUpdate, remains unchanged.
764 ZOOM_record_get may now return a record in a specific character set.
765 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
766 "from" is the character set of record as returned by target. "to" is
767 the character set to be returned. If omitted, "to" is UTF-8.
769 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
771 New ODR utility, odr_getelement, which returns name of element for
772 which encoding/decoding failed.
774 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
775 in cases where a required element was omitted.
777 Bug fix: some MARC8 sequences were not converted.
779 New ZOOM option "step" which specifies number of records to be
780 retrieved in one chunk. Used in conjunction with "start" and "count".
782 SRW support for yaz-client. Use scheme http: to use it, e.g.
785 yaz-client no longer does (un)intelligent character set conversions
786 by default. Can be enabled with charset and marc_charset commands.
788 xmalloc trace fix for 64-bit systems such as DEC alpha.
790 Solaris 2.6 compile fix.
792 New function, cql_strerror() translates SRW error codes, as returned
793 by cql_transform_error(), into human-readable English strings. Used
794 in yaz-client diagnostics when appropriate.
796 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
797 converts it into a type-1 query which is sent to the server. This
798 makes CQL available for use with all Z-servers, as opposed to the tiny
799 minority that can handle CQL queries themselves.
803 New Debian package layout similar to the Redhat Package layout.
805 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
806 and search result respectively.
810 Redhat package is now several packages: libyaz (runtime libraries),
811 libyaz-devel (development and documentation, and yaz (utility programs).
812 Package spec file by Morten Bøgeskov.
814 New member 'schema' in struct bend_fetch_rr which the name of requested
815 schema (SRW/SRU) for record (or NULL if none was given). The fetch
816 handler MAY set this to reflect the schema of the returned record.
818 New member 'display_term' in struct scan_entry. GFS now sets member entries
819 and allocates scan entries to be filled by user scan handler. In previous
820 version, entries member was allocated by the scan handler. That still works,
821 but the GFS will ignore member display_term - assuming it was NOT set by
822 the handler. The fact that the GFS now allocates the entries both allows
823 for new members and makes a scan handler easier to write.
825 Fix CQL lex buffer overflow.
827 SRW/SRU recordPacking. For SRW default recordPacking is string. For
828 SRU default recordPacking is string.
830 SRU protocol support for frontend server.
832 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
834 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
836 Added scan for the ZOOM shell (zoomsh).
840 * String Identifers for Schemas (Amendment 5).
841 http://lcweb.loc.gov/z3950/agency/amend/am5.html
842 Old definition for schema
843 Odr_oid *schema; /* OPT */
848 Z_InternationalString *uri;
849 #define Z_Schema_oid 1
850 #define Z_Schema_uri 2
853 * resultCount parameter to Sort Response (Amendment 1).
854 http://lcweb.loc.gov/z3950/agency/amend/am1.html
856 Support for SRW 1.0 over HTTP. This is an optional feature and
857 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
860 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
861 on the same port. SRW SearchRetrieveRequests are mapped
862 to bend_init,bend_search,bend_fetch,bend_close.
864 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
866 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
867 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
869 ZOOM connections are SRW based if schem http is used for hostname
870 in connect, e.g. z = ZOOM_connection_new("http://myserver");
871 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
873 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
874 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
875 distance=n, order=true/false, relation=le, prox unit=word. If
876 n is omitted, distance 1 is used.
878 Fixed problem with C compiler include path in wrong order.
880 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
881 on Solaris. Patch from Ko van der Sloot.
883 New MARC decode API. All new functions operate on a yaz_marc_t
884 handle. The most important new functions are: yaz_marc_create,
885 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
886 decode and destroy respectively. Decoder can produce formats
887 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
888 include/yaz/marcdisp.h.
890 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
891 to UTF-8, UCS-32, wchar_t or Latin-1.
893 * Prototypes for yaz_iconv_-functions moved to separate header
894 include/yaz/yaz-iconv.h.
896 Make a few private functions 'static' in unix.c. This prevents
897 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
899 For ZOOM connection, the options targetImplementation{Id,Name,Version}
900 are set when Init Response is received.
902 New function ZOOM_connection_error_x similar to ZOOM_connection_error
903 but returns diagnostic set as well.
905 New function yaz_strerror which is a portable wrapper for
906 strerror/strerror_r/GetLastMessage.
908 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
909 is returned for MARC. If type is "oai", then OAI MARC is returned.
911 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
916 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
918 Fix bad race conditions on SIGTERM and terminate gracefully in
921 Move retrieval (data1) module to Zebra since nobody seems to be
924 Add GRS-1 render for ZOOM using same format as yaz-client.
928 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
930 Fix broken ESpec handling in data1 module.
932 SGML reader parses comments and makes them part of the data1 tree.
934 Added several type casts so that YAZ compiles as C++ code.
936 ZOOM didn't handle PDU encoding failures properly.
938 Added more Bib-1 diagnostics (approved extensions).
940 GNU configure: better check for iconv.
942 More portable use of accept, getpeername. Check for socklen_t. Use
943 int/size_t if socklen_t is not defined.
947 PQF parser rejects bad queries - including those with extra
948 characters in them. PQF parser used to silently ignore that.
949 Cleaner API for PQF added, which allows you to get detailed
950 error information for bad queries (see yaz/pquery.h).
952 Fixed bug in ZOOM_record_get for type "database".
954 Implemented mini iconv library supporting conversions between
955 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
957 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
961 Fixed ZOOM C record cache so that preferredRecordSyntax and
962 elementSetName is used to check for already fetched records.
966 Added three members in bend_initrequest structure to facilitate
967 character set negotiation.
969 Fixed a bug in frontend server that could cause indefinite
970 loops under rare conditions.
972 Revised character set utilities (charneg.h) so that encoding
973 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
975 For PQF, directive @term <type> sets term type for Scan/Search.
976 Here <type> is general, string, numeric, null. The term type
977 is inherited - just like @attr.
979 New call odr_set_charset that sets character set conversion for
980 international-strings on a ODR stream. Prototype is:
981 int odr_set_charset(ODR o, const char *to, const char *from);
982 The InternationalString is still represented as C string in YAZ
983 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
984 won't). On the protocol level, you can use any encoding.
986 Support for UNIX sockets in ZOOM.
988 Solaris recv sometimes returns errno == ENOENT. It is treated as
989 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
991 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
992 both client and server. Code by Morten Bøgeskov.
996 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
997 that they can be used directly from Visual Basic. You must recompile
998 your windows APP if you're using ZOOM.
1000 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1001 Commands "lang" and "charset" sets language and character set respectively.
1002 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1003 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1005 Attributes from multiple CCL fields may be OR'ed rather than merged
1006 using directive "@field or". Fields are still merged by default -
1007 equivalent to "@field merge".
1009 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1012 Fixed bug in zget for parameter ExtendedServicesResponse.
1016 --- 1.8.6 2002/03/25
1018 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1020 Client displays USR.1:SearchResult-1 (hits per term).
1022 Additional Search Info for search in Generic Frontend Server.
1024 Fixed CCL parsing of "field=s".
1026 WIN32 installer - using the excellent NSIS software from nullsoft.
1028 Fixed CCL parsing of "field = - <number>".
1030 Added function yaz_marc_decode that decodes MARC for line mode
1031 display or XML (similar to that used by JZKit).
1033 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1034 Z39.50. But ISO/ILL was, however.
1036 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1037 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1039 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1040 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1042 --- 1.8.5 2002/02/03
1044 New YAZ client features: Command completion and new commands:
1045 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1046 Code provided by Jacob Poulsen.
1048 New call oid_trav, that visits all registered OIDs via callback.
1050 Function ZOOM_record_get now returns const char pointer rather than
1051 void pointer. It saves a lot of type casts.
1053 For YAZ client, command "auth" now allows you to set authentication
1054 in IdPass style. It is enabled when three tokens are given - order
1055 is user, group and password.
1057 Fix memory leaks in MARC record handling for ZOOM.
1059 New option for YAZ client, -k <kilobytes> that sets
1060 maximum record size. Similar to -k option for generic frontend
1061 server and yaz-ztest.
1063 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1065 Prefix query parser reports "fail" when bad attribute set is given.
1067 Fix in MARC decoder. Proximity logging. Fix for attribute set
1068 in scan handler for server. Patches by Shigeru Ishida.
1070 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1073 Configure option --with-openssl=<dir> now works when a directory is
1074 specified. Patch provided by Morten Bøgeskov.
1076 New option for YAZ client, -u <auth>, that sets authentication.
1078 ZOOM fix: error information was sometimes "missing", since error
1079 was cleared/reset too when it shouldn't.
1081 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1083 --- 1.8.4 2002/01/04
1085 Scan for ZOOM API. New object ZOOM_scanset. New functions
1086 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1087 ZOOM_scanset_destroy.
1089 New ZOOM function, ZOOM_connection_last_event, that returns type
1090 of last event (such as "receive data", "send data", "apdu received",
1093 New ZOOM option, schema, that specifies schema for retrieval.
1095 New CCL feature. Qualifiers can be aliases for one or more
1096 other qualifiers (if more than one is given, OR is used).
1098 ZOOM uses named result sets if target supports it.
1100 Two new YAZ client commands: . (dot, which sources a script of YAZ
1101 client commands), and ! (to execute shell command.). Implemented
1104 Working on Debian packages.
1106 --- 1.8.3 2001/11/19
1108 YAZ client enables named result sets only if target supports it.
1110 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1112 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1113 with key="host" to get same result.
1115 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1116 Function Z3950_resultset_record(s) returns references to records
1117 "owned" by resultset. To become owner use Z3950_record_clone.
1119 Function z_ext_record handles Extended Services. Thanks to
1122 --- 1.8.2 2001/11/12
1124 CCL Parser fix: ignore token comma when dealing with and-lists.
1126 Documentation updates for COMSTACK.
1128 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1129 Changed prototype Z3950_records. For some functions, int parameters
1130 were changed to size_t.
1132 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1135 New MARC decode/display function, marc_display_exl, which properly rejects
1136 non-ISO2709 records. YAZ client uses it.
1138 --- 1.8.1 2001/10/29
1140 Fix bug: local attribute set wasn't set correctly in PQF strings.
1144 * Old Z39.50 codecs no longer supported.
1146 Added ZOOM C binding. See http://zoom.z3950.org/
1148 Renamed states for COMSTACKs to avoid confusion with events.
1150 Implemented cs_look and proper cs_rcvconnect.
1152 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1154 Configure detects POSIX threads on OpenBSD.
1156 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1157 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1159 When error is returned from present handler, non-surrogate diagnostic
1160 is returned in present response (and fetch handler is no longer called).
1162 * Minor adjustments to pquery parser (PQF). Token characters may be
1163 escaped by using backslash (C-style).
1165 PQF parser allows string attribute values to be specified. For @attr,
1166 non-numeric characters after the equal-sign are treated as strings
1167 (e.g. @attr 9=title).
1169 CCL trunction character may be defined (@truncation in file)
1171 * function zget_ExtendedServicesRequest sets waitAction to
1172 waitIfPossible (was wait).
1174 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1177 CCL operator names may be set in field definition files (CCL_bibset).
1178 See ccl/bib1 for an example.
1180 Fixes in ASN.1 compiler for C++ compatibility.
1182 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1183 and "op_or" to avoid conflict with C++.
1185 Fixed problem with GNU readline detection on Redhat 7.0.
1187 Added step-size for Scan backend handler.
1189 Fixed bug that made the frontend server crash when no attribute
1190 set was specified for scan.
1192 Front-end server automatically switches to original working directory
1193 when installed as an NT service. Previously -w had to be specified to
1196 Added extended attributes for retrieval module (data1), so that data1
1197 records carry d1_readXML/SGML attributes. d1_read also supports
1198 null-data rules ( <tag/>)
1200 On UNIX when POSIX threads are available, a separate library libyazthread
1201 is created. Programmers should link with that library and the yaz library
1202 when using threads. The reason for the split was that some applications
1203 on Linux, such as Apache, doesn't work well when using shared objects that
1206 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1207 (or any frontend server) in SSL mode by specifying ssl: followed by
1208 address. Only tested on UNIX.
1210 Added feature for CCL module. Virtual structure s=al or s=ol generates
1211 and-list and or-list respectively instead of phrase search.
1215 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1216 log_mask_str. This was done to avoid name conflicts with other libraries
1217 (such as other PHP extensions).
1219 Added raw OID member for preferred record syntax (request_format_raw)
1220 and returned record syntax (output_format_raw) for backend fetch method.
1222 Config file yaz-config now accepts options so that it returns specific
1223 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1225 Shared library support for UNIX using GNU libtool.
1227 * Modified backend interface. Request/Response struct's replaced by
1228 one read/write C struct. For example bend_fetchrequest and
1229 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1230 Every handler - even search has to be registered in bend_init
1231 handler. This means that the YAZ library no longer refers to
1232 external functions and it makes it possible to make the whole
1233 thing a single DLL/SO.
1235 Added Segment handler for backend server.
1237 Added Zmbol/Zebra administrative functions to YAZ client.
1239 Threaded frontend server on UNIX (when POSIX Threads are available).
1240 Starting the server with option -T enables multi-threading.
1244 Added configure option --enable-comp/disable-comp to control use
1245 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1246 located in sub directory asn.
1248 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1249 in ${exec_prefix}/bin along with the other programs yaz-client and
1252 GNU automake used to maintain makefiles.
1254 Added several OID's.
1256 Changed retrieval module so that we can load records with no abstract
1257 syntax defined. Tagpaths in these records are fully composed of string
1260 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1264 On UNIX, the generated makefile now supports a proper 'make install'.
1265 The prefix can be set via GNU configure to set the install location
1266 (default is /usr/local).
1268 * YAZ programs client and ztest were renamed to yaz-client and
1269 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1270 locations, such as /usr/bin,/usr/local/bin,etc.
1272 * YAZ Header files were moved from include to include/yaz. YAZ Header
1273 files are referred to as include <yaz/log.h> rather than <log.h>.
1274 The YAZ include path (-I ..) is therefore the same as before. Programmers
1275 should update their #include statements or use -Ipath/include/yaz
1276 instead. The main motivation for doing this change is that YAZ header files
1277 can be installed in "standard" locations /usr/include,/usr/local/include
1278 without introducing conflicts, since ALL YAZ header files are stored
1279 in subdirectory yaz (under /usr/include for example).
1281 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1282 rather than project/workspace files. We switched because project files
1283 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1286 Changed name of logging function, logf, to yaz_log, to prevent name
1287 clash with some math-log functions. The YAZ header log.h defines logf
1288 to yaz_log (#define) so there should be no incompatibilities by this
1291 Added bend_start/bend_stop handlers for server. These handler are
1292 called on start/stop of server. For windows they are called whenever
1293 a service is started/stopped.
1295 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1296 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1297 in util/yc.tcl. The auto-generated C code structures are, in a few
1298 cases, incompatible with the old decoders. There are differences in the
1299 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1300 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1301 The preprocessor variable ASN_COMPILED is defined when the compiled
1302 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1303 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1304 wish to use the old encoders/decoders you can specify --disable-yc
1307 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1308 version so that it supports both new - and old version of DB Update
1310 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1311 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1312 change. The name parameter can be set to 0 in which no name is specified
1313 for the construction. The macros odr_implicit and odr_explicit sets name
1314 parameter to zero for the construction involved. New macros
1315 odr_implicit_tag and odr_explicit_tag are similar to the others,
1316 except that a name parameter is added. For programmers' that don't use
1317 ODR they probably only need to change the call to z_APDU and z_External.
1319 Added access control facility by interfacing the TCP wrapper library.
1320 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1321 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1322 name of the daemon and enables the access control as specified in
1323 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1325 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1326 den Dool <H.M.vdnDool@kub.nl>.
1328 Added reference ID parameter to most functions in server API - refer
1329 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1331 Changed name of ccl library to libccl.a (was ccl.a).
1333 Fixed bug in decoder for Explain (Category TargetInfo).
1335 Added support for GNU readline in client. Thanks to Jacob Poulsen
1336 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1338 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1339 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1340 IMPLEMENTATION! This change was made to the development version before
1341 the ZIG decided to retract the amendment. If any users MUST be
1342 compatible with the original Update definition, PLEASE CONTACT US, and
1343 we will include a separate definition corresponding to the old Update
1344 ES. Note that because of the change to the ASN.1 of the
1345 TaskPackageRecordStructure we cannot define a single structure that
1346 will support both versions.
1348 * Added const modifier to buffer parameter for some ODR/BER encoding
1349 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1350 completeWAIS, odr_dumpBER.
1352 Fixed bug in client.c which caused a crash when a scanResponse didn't
1353 contain positionOfTerm.
1355 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1356 * will cause an error in a client if a non-YAZ target sends both a
1357 * list of Scan entries and non-surrogate diagnostics.
1359 Retrieval module enhancements. Tag sets may be typed in the reference
1360 to it. From the .abs-file the "tagset" directive takes a third optional
1361 integer type for the tag set referenced. From a .tag-file the "include"
1362 directive takes a third optional type as well. The old "type" directive
1363 in the tag set itself is still recognized but acts as the default type
1366 Backend interface change. Individual Scan terms returned from bend_scan
1367 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1368 in include/backend.h.
1370 Retrieval module enhancements. Multiple tag sets and attribute sets may
1371 be specified in abstract syntax specs. Revised the error/warning for
1372 logging messages reported by the retrieval module when reading the
1375 Object Identifier system (oid_..) changed. The API is backwards
1376 compatible but the oid-routines now allocates new OID's when needed.
1377 Raw OID's may be specified in oid_getvalbyname.
1379 YAZ now uses GNU configure to generate Makefile(s).
1381 * Minor changes in some of the member names of DeleteResultSetRequest and
1382 DeleteResultSetResponse. See include/proto.h.
1384 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1385 and added member 'languages' in TargetInfo (which was missing).
1387 Changed the way attribute sets are handled in the retrieval
1388 module. These are now cached, just like the abstract syntaxes
1391 Changed YAZ so that it links with compiled ASN.1.
1393 Added Explain-schema definitions and mapping routines. The following
1394 Explain categories have been implemented: AttributeDetails,
1395 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1397 Fixed minor bug in Windows version of Server Library.
1399 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1401 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1403 Added EXTERNAL: UNIverse Resource Report (non-standard).
1405 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1406 ENUMERATED and SET OF.
1408 * Added 'const' to some of the char pointer arguments for the
1409 functions, data1_read_node, data1_getelementbytagname,
1410 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1413 Fixed bug in data1_insert_taggeddata - the last_child member of
1414 parent wasn't initialised.
1416 * Changed data1_read_record and data1_read_node so that the supplied
1417 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1418 doesn't refer to any parts of the "SGML"-buffer.
1420 Fixed bug in server library (Windows version of statserv_remove).
1422 * Changed code so that it compiles as C++. The type definition
1423 of Odr_fun which is a member of Odr_arm was changed. The result is,
1424 that an explicit typecast is needed for the fun pointer when
1425 using Odr_arm - as in:
1426 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1428 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1430 Implemented the new structured date and time definition as approved
1431 by the ZIG. Added schemaId element to the specificTag in Espec-1
1432 (also approved at the last ZIG). Thanks to RVDM.
1434 Added some Object identifiers (RVDM).
1436 Changed the Update Extended Service (RVDM).
1438 Added command "refid" to client which specifies referenceId for
1439 the following requests.
1441 Implemented extended service handling for server. See ztest.c
1442 for an example as well as backend.h. New handlers are registerd
1443 in the Init handler.
1445 * Changed interface for sort in server.
1447 Added new members to statserv_options_block. It allows a server
1448 to read options from another source than just the command line. Thanks
1449 to Charles Woodfield.
1451 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1452 renamed to zboolean. Some C++ compilers complained about the name.
1454 Minor changes to gils.abs. Added index 's' (sort) on title
1455 and date/time-last-modified.
1457 --- 1.4pl2 1998/1/30
1459 Fixed bug in server library regarding inetd mode (-i). This bug
1460 was introduced by release 1.4.
1462 --- 1.4pl1 1998/1/29
1464 Added sort facility in client and backend server interface.
1466 Fixed problem with dependencies in Makefile(s).
1468 Fixed bugs for encoders/decoders of extended services and
1471 Implemented sub-tree feature for schemas. Sub-trees are
1472 referenced in *.abs-files. See explain.abs for an example
1473 of the use of this feature.
1475 Modified bib1.att; local attributes for ANY didn't include
1476 ANY itself (only affects use of the retrieval module).
1478 Fixed bug in plain SGML reader in function data1_read_node:
1479 tags with prefix "var" was incorrectly interpreted as variants.
1481 Added feature "sub-schemas" to enable references to - and definitions
1482 of - group of elements.
1484 * Removed member parent from type data1_element (in data1.h).
1486 Implemented function odr_nullval() that returns the value of
1489 * Removed member num_children from data1_node (in data1.h).
1491 Made NT service interface part of the server library. The
1492 function statserv_main uses the NT service when required and
1493 calls the statserv_start / statserv_close routines.
1495 Routine zget_SearchRequest and zget_PresentRequest fills
1496 resultSetName/Id member with "default" instead of "Default".
1498 Fixed memory leak in server. Request queue member wasn't freed.
1500 Fixed nmem_exit so that memory is freed.
1504 Revised the CCL parser utility to be thread safe.
1506 Added function, oid_ent_to_oid, to replace the function
1507 oid_getoidbyent, which is not thread safe.
1509 * Added nmem_init and nmem_exit to initialize and release
1510 NMEM resources. Function nmem_init should be called once in the
1511 initial thread before NMEM/ODR is used. statserv.c and client.c
1512 have been changed accordingly. The change was necessary to make
1513 NMEM thread safe. The NMEM memory pool is shared amongst threads
1514 in a process. Unix-based applications will still work fine without
1517 Added NT Services interface for the the Z39.50 (statserv) Server.
1518 Refer to the ztest.c source on the usage.
1520 Windows 95/NT port using MSVC5.0. Project files are included in the
1523 * Defined new 'global' handle for the retrieval (data1) system. The
1524 new handled, data1_handle, describes the state of the data1 system.
1525 This handle is passed as first argument to virtually all
1526 data1 related routines. The functions data1_create and data1_destroy
1527 creates and destroys a data1 handle respectively.
1529 Added ODR encode stream member to all backend request structures
1530 init, search, scan etc. This stream should be used to allocate all
1531 memory used for the response when thread safe operation is needed.
1533 Changed the comstack utility, cs_addstr, to be thread safe. The
1534 returned hostname string returned by the function is now part the
1537 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1538 function. The cs_straddr takes a COMSTACK handle as argument, so this
1539 function must be used after cs_create and before bind/connect.
1540 This function is thread safe.
1542 Moved test server to 'ztest' directory - generic server code still
1543 in 'server' directory.
1545 Made prefix query (pquery.c) utility thread safe.
1547 Added new function modifier YAZ_EXPORT to 'export' public DLL
1548 functions when using windows (see include/yconfig.h).
1550 Added definitions to the OID database (util/oid.c) (RVDM).
1552 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1554 Added call to ccl_rpn_delete in client program.
1556 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1557 release of RPN structure.
1559 Added support for C++, headers uses extern "C" for public definitions.
1560 With input from RVDM.
1562 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1563 Thanks to Ronald van der Meer (RVDM).
1565 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1567 Added support for private extensions to the OID database
1568 (oid_setprivateoids()). Thanks to RVDM.
1570 Added optional, physical ANY (key replication)
1572 Fixed null-reference problem in GRS-1 output filter.
1574 Proximity operator added to Prefix Query Format (PQF).
1576 In test client command "base" accepts multiple databases.
1578 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1582 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1584 Smallish bug-fixes in the new encoders/decoders (explain).
1586 Bug fixed in DeleteRequest.
1588 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1590 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1592 Added SOIF syntax (using private OID for now) to retrieval module and client.
1594 Added Update extended service.
1596 Added SearchResult-1 additional info structure.
1598 Added optional CCL (ISO8777) interpreter as separate module. Available
1601 --- 1.2 1996/6/10 (1st anniversary release)
1603 Added Summary record syntax. Lightly tested.
1605 Added OPAC record syntax. Untested.
1607 Added ResourceReport service encoders/decoders. Untested.
1609 Fixed bug in z_Unit - wrong tagging on unitSystem.
1611 Fixed bug in the DiagRecs decoder.
1613 Added options for max PDU size and session timeout to frontend-server.
1615 Added documentation of query-language parsers and other supporting utilities.
1617 [frontend-server] Added Attribute set to the bend_scanrequest API.
1619 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1620 surrogate diagnostics were generated.
1622 [retrieval] Allow multiple local values for attribute.
1624 [retrieval] Allow multiple attributes per element in .abs files. index type.
1626 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1628 --- 1.1pl2 1996/4/10
1630 Minor changes, mostly specific to Zebra's requirements (retrieval)
1634 Repaired bug in frontend server when running multiple listening
1635 endpoints in dynamic mode.
1637 z_External() now won't break if a known, ASN.1 value comes encapsulated
1638 in an octet-string. The value will pass through unmodified in an Odr_oct.
1640 Added a bit of code to the demo client to decode & display
1641 ASN.1-structured records represented in the octet-aligned branch of
1642 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1644 Added z_ext_getentbyref() to the ASN module. Doc updated.
1646 * Completed the SCAN definition in the ASN module. This may break SCAN
1647 code based on older YAZ-versions at compile-time. The fix is easy -
1650 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1651 under the SCAN definition. Remember to initialize this, server-people.
1653 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1654 that this does not extend to ODR and ASN.
1656 Comstack allows insertion of established socket (primarily for
1657 inetd-operation of servers). Doc updated.
1659 Front-end server can now start from the inetd in TCP mode. Doc
1662 --- 1.0pl4 1996/1/24
1666 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1667 the rank and record number.
1669 Adjustments to the frontend server.
1671 Fixed diagnostic BER dumper. It ignored the file argument.
1675 Various changes to retrieval module.
1677 Changed the union discriminators of the protocol files from enums to
1678 ints paired with #defines.
1680 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1683 *Changed operator in the RPN structure to 'roperator', again to avoid a
1686 Fixed problems in Explain decoders/encoders.
1688 --- 1.0pl2 1995/12/6
1690 Memory bug in log module fixed.
1692 --- 1.0pl1 1995/12/5
1694 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1696 Bug in Explain DatabaseInfo module fixed.
1698 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1702 The shift to v1.0 signals that we now consider the *core* functionality
1703 of YAZ reasonably stable (the core being more or less equivalent to
1704 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1705 tested (Explain not at all - though that will happen soonish).
1707 Minor changes to code to support Windows port.
1709 Various minor changes after we're getting to use GRS-1 & co. more.
1711 Added Espec-1 format.
1713 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1714 of the protocol and it cannot be selected when encoding (maps into 'string'
1715 when decoding). Needed to talk to some servers.
1717 Demo client can request simple element set names.
1719 Added Diagnostic Format encoders/decoders.
1721 Added simple Close handling to frontend server (no hooks for resource
1722 reporting yet), and demonstration client.
1724 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1726 --- 1.0b3 1995/08/24
1728 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1729 handled incorrectly when records were requested in the searchResponse. This
1730 will only affect you if you use the frontend-server.
1732 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1733 Test-client will ask for and print GRS1. Ztest will return dummy records
1736 Added Explain encoders/decoders to the service-level API. Untested.
1738 Added Extended Services: Item Order encoders and decoders to the Service-
1739 level API. Untested. We could use a recent copy of the pertinent bits
1740 of the ILL protocol to add those bits.
1742 Added diagnostic format 1 encoders/decoders to the service-level API.
1745 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1746 odr_cons.c, which causes a more correct output.
1748 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1749 was always set to 0 when no records were requested in the searchRequest.
1751 * Added better external-handling. This shouldn't harm old code that
1752 *encodes* externals. It can break code that looks for a
1753 'single-ASN1-type' representation, since those types that are known
1754 are now decoded immediately. Look at the SUTRS sample code in
1755 seshigh.c and client.c. Documentation updated.
1757 Handling of structured records in bend_fetchresponse. Length -1 marks
1758 structured record, type is deduced from format field.
1760 --- 1.0b2 1995/06/27
1761 Fairly quick maintenance release to add SUTRS support.
1763 Fixed handling of SUTRS records in the demonstration client.
1765 * Added format field to the bend_fetchrequest and bend_fetchresponce
1766 structures of the backend API (frontend server). When the record is
1767 returned, the value of the format field is mapped to an OID. The
1768 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1769 of the record. The special value VAL_NONE in the bend_request means
1770 that no specific format was requested by the client. Documentation
1771 updated accordingly. Test server (ztest) will return a fixed dummy
1772 SUTRS record if your client requests SUTRS.
1774 Documentation updated accordingly.
1776 You can now set external libraries and RANLIB support in the top-level
1780 First public release.
