3 ASN.1 compiler 0.4: generates brief Doxygen file header for
6 Utility yaz_iconv now supports conversion to MARC-8.
8 New facilities for the MARC module. The reading - and writing of
9 content are separate methods for the yaz_marc_t handle. The following
10 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
11 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
12 format). Write functions have prefix yaz_marc_write_.. The existing
13 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
14 available. Removed support for OAI-MARC and simplexml (not the
17 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
18 to be returned for this connection.
22 Allow multiple languages and charsets to be specified with
23 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
24 negcharset iso-8859-1,utf-8
26 Translation of proximity nodes from CQL into PQF now works.
28 Moved to automake 1.8, 1.9.
30 Added function yaz_log_set_handler which allows a log handler to be
31 installed. This handler will be called for all log messages. Output
32 to file is also produced; but that can be disabled by passing NULL
33 fname to yaz_log_init_file.
35 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
37 For SRW (including GFS), accept application/soap+xml as content-type
40 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
41 produces NO stylesheet reference even if a default stylesheet is specified
46 Updated Windows package to include yazd.dll + yazd.lib for the
47 Development component.
49 If the environment variable YAZ_LOG is set, then it is used as a
50 string indicating the default level of logging to use if not
51 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
52 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
53 used as before. So, for example, to omit warnings from YAZ logging,
56 cql_transform() now map structure and other attributes before indexes,
57 so that index-specific structures and other attributes can override
58 defaults. So now a combination of mapping specifications such as:
60 index.dc.date = 1=date-modified 4=5
63 cql_transform() now also respects the "always" mapping specification,
64 which establishes an initial set of attributes to be used for all
65 terms except where overridden by more specific attributes associated
66 with the index, relation or modifier.
68 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
69 which mode to use; one of "post", "get" or "soap" (SRW, default).
71 Fixes for yaz_iconv routines: changed trie-based character set conversions
72 to use only non-negative values for bit fields due to Sun's C compiler not
73 supporting negative values.
75 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
76 sequences where not read correctly. Fix by Rustam Usmanov.
78 Updated win/makefile to use options, settings which makes things
79 compile with VS C 2005.
83 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
85 In ZOOM socket code, use select instead of poll on MacOSX.
87 ZOOM-C now support client-side compilation of CQL into RPN that is
88 sent to the server, enabling CQL to be used against all Z39.50
89 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
90 ZOOM_query object, and submit it using ZOOM_connection_search().
91 The CQL-to-RPN translation uses a configuration file, the name of
92 which must be specified in the Connection's "cqlfile" option.
94 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
95 function, which takes as its start-term parameter a ZOOM_query object
96 (which may have had either CQL or RPN set into it).
101 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
102 GFS to support this as well. Backend handler, bend_srw_update, does the
103 update work. Code contributed by Ko van der Sloot.
105 Allow retrieval of Search Result-1 information in ZOOM by the use of
106 options that are attached to a result set. ZOOM documentation updated
109 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
110 UTF-8 conversion. Patch by Raj Patel.
112 Added option -m to GFS to control formatting of timestamps in log file.
114 Added 'exit' as synonym for 'quit' in yaz-client
116 Added support for specifying SRW resultSetId + resultSetIdleTime in a
117 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
118 for the new members. Patch by Ko van der Sloot.
120 Added support for SRU POST. It is supported for content-type
121 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
123 Do not build the separate Multi-threaded (MT) library libyazthread.la.
124 Instead make the library libyaz.la multi-threaded. Threading as a whole
125 can still be disabled by configure option --disable-threads. Previosly,
126 with older GLIBCs there were problems with MT libs under Apache. This
127 has now been fixed a long time ago.
129 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
132 CQL module modified to be case insensitive for relations/indexes/operations.
134 Fixed bug in CQL transform code: incorrect value relationModifieder
137 Added 'show all' command for yaz-client which retrieves all results
140 Added new yaz-client, xmles, which takes a (private) OID and
141 a document to be sent as an extended service request.
143 Describe new yaz-client commands wait_response and set_auto_wait.
145 Increase TCP/IP listener backlog from 3 (which I am guessing was
146 copied from the SunOS manual entry way back when) so SOMAXCONN, so
147 that the socket will queue as many incoming connections as it's able
148 to handle ongoing connections. In other words, it will never now
149 refuse a connection that it would be able to handle merely because
150 it's not got around to accepting() enough of the pending connections
151 yet. This is the behaviour anyway under Linux, where the listen()
152 argument is ignored; but not under BSD and on systems such as
153 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
154 YAZ-based servers should now be uniform across operating systems in
157 yaz-marcdump uses 64-bit file access on some systems. This is enabled
158 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
159 This allows yaz-marcdump to read large MARC batches (>2 GB).
161 Modified all YAZ source files - except the source which is auto-generated
162 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
165 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
166 corresponding to the existing *_setl() function. These allow option
167 values containing arbitrary valuues.
169 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
170 ZOOM_resultset_sort() in new applications. Its behaviour is identical
171 except that it returns an indicator of whether or not the sort
172 criterion was accepted (0 for OK, -1 for invalid).
176 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
177 MARC output rather than returning "new" buffer.
179 yaz-client warns about unknown init options.
181 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
185 Added support for SRW sort in Generic Frontend Server. Patch
186 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
187 sortKeys - or NULL if none is provided.
189 Fixed bug #307: It was impossible to specify indefinite/no timeout
190 for ZOOM_event. Special timeout value -1 now means indefinite timeout
193 Added support for multiple languages and charsets to be specified in
194 ZOOM. Each charset/language is separated by a blank. If negotiation is
195 in effect in init-response, Option
196 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
197 Code based on patch by Vasiliy Osadchuk.
199 Fixed bug #306: infinite recursion that occurred when calling
200 yaz_log_level_init as the first call (before other log level or
203 Fixed bug in scan handling in front end server: if preferred-Position-In-
204 Response was non-present, a NULL pointer referece was performed.
208 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
209 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
210 now defined for all those error codes. So instead of putting 109 in
211 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
212 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
214 Modified the yaz-marcdump utility to skip garbage bytes between MARC
217 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
219 Program yaz-client now exits and produces an error message if multiple
220 Z39.50 servers are specified on the command line (none or one allowed
223 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
228 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
230 Fixed bug #272: Preserve spacing for CCL terms.
234 Added support for virtual hosts and multiple backend servers for
235 the YAZ frontend server. The configution is XML based and
236 support specificition of CQL to RPN mappings and explain information.
237 See section "Virtual Hosts" in the YAZ manual.
239 Extended OPAC display utility. OPAC display utility renders
240 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
241 to supplement yaz_marc_decode_wrbuf.
243 Fixed a bug in MARC decoder that could caused it to crash for some
244 invalid MARC records. More diagnostics and warnings where added in
245 XML output (warnings, etc are stored in comments).
247 --- 2.0.34 2005/02/08
249 Fixes for UNIX domain sockets. Bug #261.
251 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
253 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
254 Added yaz_marc_subfield_str which defines subfield lead string which is
255 used in YAZ_MARC_LINE format. Default string is blank+$. Added
256 yaz_marc_endline_str which defines end of fields string used in
257 YAZ_MARC_LINE format. Default string is newline.
259 Experimental support for MarcXChange. This format can be produced
260 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
261 http://www.bs.dk/standards/MarcXchange.xsd
263 Added yaz-client commands scansize that sets maximum number of
264 entries to be returned by scan.
266 --- 2.0.32 2005/01/11
268 Added support for SRW scan in yaz-client and Generic Frontend Server.
270 * Added whereInList member to SRW Scan Term.
272 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
274 Fixed NMEM system to return aligned blocks on the smallest boundaries
275 that are suitably aligned for all possible types on the particular
276 architecture YAZ is being built for.
278 --- 2.0.30 2005/01/04
280 Fixed numerious warnings that was issued with newer versions of GCC.
282 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
283 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
286 Make YAZ Generic Frontend Server slightly faster.
288 Enhance (and reduce) logging for Generic Frontend Server.
290 Revert YAZ log system so that it flushes every write operation
291 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
293 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
294 instead of LOG_, due to name clash with syslog(3). LOG_ are still
295 present. New applications should define YAZ_USE_NEW_LOG=1 - this
296 will effectively disable old definitions.
298 --- 2.0.28 2004/11/09
300 Added yaz_log_time_format which specifies log format using
303 Added yaz_log_module_level which returns mask for a module. Value
304 is non-zero mask a if module is enabled; zero if disabled.
306 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
307 in include/yaz/cql.h.
309 Fixed bug #176: Dont throw diagnostics on empty SRU args.
311 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
313 Fixed bug #172: RPM builds does not enable SSL.
315 Doxyfile.in part of dist. Doxyfile generated by configure.
317 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
318 are given and the corresponding component does not exist.
320 Extend CCL documentation in YAZ reference. Describe r=r.
322 --- 2.0.26 2004/10/01
324 Fixed MARC->MARCXML conversion to properly deal with
325 fields, subfields, indicators having non-ASCII characters.
327 Fixed MARC->MARCXML conversion so that ASCII control characters
328 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
331 Added YAZ GFS support for conversion from Z39.50 surrogate
332 diagnostics to SRW surrogate diagnostics.
334 Bug fix: YAZ GFS did not return schema in explainResponse.
336 --- 2.0.25 2004/09/30
338 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
339 now converts recordSchema to elementSetName as well as schema URI.
341 Fixed bug in COMSTACK that prevented HTTP request packages from being
344 --- 2.0.24 2004/09/29
346 Added CCL facility r=r "range" which is similar to r=o "ordered" but
347 does not require white-space before and after the dash in a range, e.g.
348 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
351 Fixed a few AC_TRY_LINK configure tests that did not operate properly
352 due to new GCC removing "redundant" code.
354 Added yaz-client commands scanpos and scanstep that sets preferred
355 position and step-size for scan.
357 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
359 Added CCL utility ccl_qual_buf which parses one or more CCL
360 spec lines in a buffer.
362 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
363 of name and value - ignoring empty lines and comments.
365 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
367 Added odr_get_element_path which returns current element path for an
368 ODR handle. This utility is useful in error handling or user-defined
371 Added ODR_PRINT utility odr_set_stream which is is a more generic
372 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
373 to a write function and pointer to close function. The close function - if
374 non-NULL - will be called during odr_destroy.
376 Fixed bug in CCL parser where truncation char was not removed from
377 right side when truncation=both was in effect.
379 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
382 --- 2.0.23 2004/08/11
384 Fix buffer overrun in CQL parser when dealing with proximity (%).
386 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
387 to UTF-8/UCS conversion is now only based on codetables.xml.
389 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
391 --- 2.0.22 2004/08/06
393 Add support for more "commit changes" in ZOOM (uses Extended Services).
395 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
398 Yet another small fix for configure of SSL.
400 --- 2.0.21 2004/05/14
402 Fix SSL libs for configure when --with-openssl=DIR is given.
404 --- 2.0.20 2004/05/10
406 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
408 SSL comstack now uses yaz.pem certificate file on server side
409 by default. Certificate filename can be configured by calling
410 comstack function cs_set_ssl_certificate_file before cs_bind is used.
412 Fix bug regarding multiple calls to ZOOM_connection_connect.
414 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
416 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
417 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
419 ZOOM now allows inspection of X509 peer certificate for verification.
420 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
422 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
423 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
424 as "modular" but it simplifies things.
426 Added cs_get_peer_certificate to that returns peer X509 PEM.
428 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
429 NULL if SSL is unavailable.
431 Documentation about MARC decoding tools.
433 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
435 --- 2.0.19 2004/03/30
437 Rename CHANGELOG to NEWS to follow GNU style packing.
439 Fix bug with missing initialization of member in init_diagnostics.
440 This bug affects threaded version of GFS server.
442 --- 2.0.18 2004/03/20
444 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
447 Ensure zlib.dll is packed with Windows install.
449 --- 2.0.17 2004/03/17
451 Fix encoding of xsd:string to use text instead of CDATA.
453 Fix endless loop in CQL parser with unbalanced ".
455 Use a more compact way to store MARC-8 conversion tables.
457 --- 2.0.16 2004/03/16 Debian only
459 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
462 Update CQL parser to use new CQL 1.1 modifiers for booleans and
467 --- 2.0.15 2004/03/01
469 Another fix for decoding of XML packed records.
471 --- 2.0.14 2004/02/25
473 Fixes for Chunked encoding. White space not ignored after length spec.
475 Update NS and use default NS for SRW diagnostic elements.
477 --- 2.0.13 2004/02/23
479 Implement ZOOM_resultset_cache_reset which resets record cache.
481 Implement ZOOM_resultset_sort which sorts a result set.
483 Implement chunked HTTP transfer.
485 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
487 --- 2.0.12 2004/02/16
489 Added member 'schema' to bend_explain_rr structure so that backend
490 can specify explain record identifier. Defaults to Zeerex 2.0.
492 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
494 --- 2.0.11 2004/02/16
496 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
499 Added init command for yaz-client which sends "extra" init request.
501 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
502 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
504 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
506 Make ZOOM error code for "invalid query".
508 Fixed compilation for SSL which wasn't properly enabled for all platforms.
510 --- 2.0.10 2004/02/05
512 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
515 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
517 Added option -p <file> to make Generic Frontend Server to write PID file.
519 Added option -D to put Generic Frontend Server in background on its own.
521 Make ZOOM C recognize option "password". If unset, "pass" is used
522 (for backwards compatibility).
524 Fixed a bug in Generic Frontend Server that could make it crash if a
525 client sets characterSetNegotation bit, but didn't pass negotiation stuff
528 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
529 Must be issued before open, in order to be in effect.
531 --- 2.0.9-6 2004/01/12 Debian/Windows
533 Make the SRU server more picky WRT unknown params, etc.
535 Bug fix: ZOOM scan response didn't return displayTerm - when present.
537 New YAZ client command, options, that sets Z39.50 options.
539 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
540 options from a string of tokens (one token for each option bit).
542 Update SRW diagnostic code messages.
544 --- 2.0.9-5 2004/01/07 Debian/Windows
546 Handle user defined stylesheet for SRW/SRU.
548 --- 2.0.9-4 2004/01/06 Debian/Windows
550 Fix bug in decoding of Content-Length.
552 --- 2.0.9-3 2004/01/06 Debian/Windows
554 Fix a bug with decoding of XML packed records.
556 --- 2.0.9-2 2004/01/05 Debian only
558 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
560 Fix bug in SRW/SRU diagnostics decoding.
564 Fixed bug in Generic Frontend Server which could drop records exceeding
565 preferred message size. Reported and fixed by Irina Dijour.
567 Fixed calculation of package size for structured records in Generic
568 Frontend Server. Reported and fixed by Irina Dijour.
570 Fixed namespace for SRW/SRU diagnostics.
572 Fixed SEGV in yaz-client that occured for HTTP connection errors.
576 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
577 this version is incompatible with version 1.0 and older YAZ SRW/SRU
580 CQL changes to reflect recent changes to the specification:
581 * Documentation talks about context sets instead of index sets.
582 * Documentation talks about indexes instead of qualifiers.
583 * The CQL-to-PQF transformer's configuration file now uses
584 "index.set.name = <attributes>" instead of the old form
585 "qualifier.set.name = <attributes>". (Both forms are still
586 understood but the latter is deprecated.)
587 * CQL terms with no explicit index specified are now interpreted as
588 cql.serverChoice instead of srw.serverChoice (which of course
589 behaves exactly the same.)
593 MARC conversion can now generate ISO2709 output in another
594 character set. yaz-marcdump uses this facility if you invoke it
597 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
598 functions from there can be used from C++.
602 Frontend server now transfers memory from decoded packages to stream
605 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
606 references to show up.
608 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
609 the ZOOM Abstract API. The older names for the same options are still
610 also supported for the benefit of old applications.
612 ZOOM-C supports "implementationId" and "implementationVersion" options
613 to go along with "implementationName". These allow the user code to
614 specify identification strings to be sent to servers.
615 Add OID for the new ExtLite attribute set.
617 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
618 as requested/supplid by Ere Maijala <ere@atp.fi>
620 For generic frontend server, reverse the order of
621 "toolkit-supplied / application-supplied" strings sent as implementationId,
622 Name and Version. Also, remove the spaces around the slash. This brings
623 the GFS in line with the behaviour of ZOOM-C on the client side.
625 Add function ZOOM_scanset_display_term.
627 yaz-client shows scan displayTerm if present.
629 Utility yaz-iconv is now installed by default along with the man page
632 Extend configure check for OpenSSL to use pkg-config where available (such
635 Incorporate patch by Morten Bogeskov which allows a Unix file socket
636 server to specify uid/gid/mask for socket using the format
637 unix:[user=uid,][group=gid,][umask=mask,]file=path
638 If file= is omitted the existing format is assumed, e.g.
640 in which case the mask is 0666 (rw for everybody).
642 Major restructure of YAZ source. All source in libyaz is in src directory.
643 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
644 util (utility programs such as ASN.1 compiler, yaz-marcdump).
646 Added man page for utility yaz-marcdump (used to be called marcdump).
647 yaz-marcdump is installed by 'make install'.
649 Fixed a memory leak in Generic Frontend Server that occurred when decoding
650 of incoming package failed.
652 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
654 Change prototype of odr_perror: add const to message string.
656 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
658 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
659 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
660 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
661 DNS lookup. There should not be any compatibility problems with this
662 assuming that blocking=1 or 0 is used.
664 Fix bad reference in UNIX comstack in function cs_addrstr.
666 Fix for compilation on AIX.
668 The generic front-end server (server/seshigh.c) now supports returning
669 Init diagnostics to the client in User-information-field, in
670 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
675 Allow any CQL relation (not just all,any,exact,scr).
677 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
678 that features the same UI.
680 Implemented command update0 in YAZ client which is equivalent to
681 update but uses old of Ext Update ASN.1.
683 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
684 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
685 Previously no OID was used for this info.
687 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
688 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
689 returns 'malformed search term' otherwise.
691 SortResponse member resultCount now set to NULL in sort handler of
694 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
697 Add three new utility functions for translating OIDs between various
698 formats -- symbolic name such as "Usmarc", minus-1-terminated int
699 arrays and dotted strings such as "1.2.840.10003.9.5.1":
700 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
701 char *oid_to_dotstring(const int *oid, char *oidbuf);
702 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
704 Reverted modifications for ES Update definition for z_IU0Update
705 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
706 is back to YAZ 2.0.2.
708 String value attributes for CCL parser.
710 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
711 which their FirstSearch server returns in Init responses, sometimes
712 carrying useful diagnostic information when Init fails. This has the
713 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
714 "z39.50/oclcui.asn", where its definition is somewhat different from
715 what OCLC document on their web-site, as required to interoperate with
718 Support for anonymous authentication in yaz-client. Use the command
721 * Fix the OID of the Index Data-local "admin" Extended Service from
722 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
723 the 1000, which indicates a locally-defined OID, was a mistake.
727 Fix CCL directive @case handling so that it affects string match for
728 both CCL keywords and qualifiers.
730 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
731 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
732 Decoder has been updated with ASN.1 changes as listed in
733 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
734 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
735 z_IUUpdate, remains unchanged.
737 ZOOM_record_get may now return a record in a specific character set.
738 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
739 "from" is the character set of record as returned by target. "to" is
740 the character set to be returned. If omitted, "to" is UTF-8.
742 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
744 New ODR utility, odr_getelement, which returns name of element for
745 which encoding/decoding failed.
747 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
748 in cases where a required element was omitted.
750 Bug fix: some MARC8 sequences were not converted.
752 New ZOOM option "step" which specifies number of records to be
753 retrieved in one chunk. Used in conjunction with "start" and "count".
755 SRW support for yaz-client. Use scheme http: to use it, e.g.
758 yaz-client no longer does (un)intelligent character set conversions
759 by default. Can be enabled with charset and marc_charset commands.
761 xmalloc trace fix for 64-bit systems such as DEC alpha.
763 Solaris 2.6 compile fix.
765 New function, cql_strerror() translates SRW error codes, as returned
766 by cql_transform_error(), into human-readable English strings. Used
767 in yaz-client diagnostics when appropriate.
769 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
770 converts it into a type-1 query which is sent to the server. This
771 makes CQL available for use with all Z-servers, as opposed to the tiny
772 minority that can handle CQL queries themselves.
776 New Debian package layout similar to the Redhat Package layout.
778 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
779 and search result respectively.
783 Redhat package is now several packages: libyaz (runtime libraries),
784 libyaz-devel (development and documentation, and yaz (utility programs).
785 Package spec file by Morten Bøgeskov.
787 New member 'schema' in struct bend_fetch_rr which the name of requested
788 schema (SRW/SRU) for record (or NULL if none was given). The fetch
789 handler MAY set this to reflect the schema of the returned record.
791 New member 'display_term' in struct scan_entry. GFS now sets member entries
792 and allocates scan entries to be filled by user scan handler. In previous
793 version, entries member was allocated by the scan handler. That still works,
794 but the GFS will ignore member display_term - assuming it was NOT set by
795 the handler. The fact that the GFS now allocates the entries both allows
796 for new members and makes a scan handler easier to write.
798 Fix CQL lex buffer overflow.
800 SRW/SRU recordPacking. For SRW default recordPacking is string. For
801 SRU default recordPacking is string.
803 SRU protocol support for frontend server.
805 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
807 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
809 Added scan for the ZOOM shell (zoomsh).
813 * String Identifers for Schemas (Amendment 5).
814 http://lcweb.loc.gov/z3950/agency/amend/am5.html
815 Old definition for schema
816 Odr_oid *schema; /* OPT */
821 Z_InternationalString *uri;
822 #define Z_Schema_oid 1
823 #define Z_Schema_uri 2
826 * resultCount parameter to Sort Response (Amendment 1).
827 http://lcweb.loc.gov/z3950/agency/amend/am1.html
829 Support for SRW 1.0 over HTTP. This is an optional feature and
830 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
833 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
834 on the same port. SRW SearchRetrieveRequests are mapped
835 to bend_init,bend_search,bend_fetch,bend_close.
837 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
839 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
840 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
842 ZOOM connections are SRW based if schem http is used for hostname
843 in connect, e.g. z = ZOOM_connection_new("http://myserver");
844 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
846 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
847 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
848 distance=n, order=true/false, relation=le, prox unit=word. If
849 n is omitted, distance 1 is used.
851 Fixed problem with C compiler include path in wrong order.
853 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
854 on Solaris. Patch from Ko van der Sloot.
856 New MARC decode API. All new functions operate on a yaz_marc_t
857 handle. The most important new functions are: yaz_marc_create,
858 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
859 decode and destroy respectively. Decoder can produce formats
860 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
861 include/yaz/marcdisp.h.
863 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
864 to UTF-8, UCS-32, wchar_t or Latin-1.
866 * Prototypes for yaz_iconv_-functions moved to separate header
867 include/yaz/yaz-iconv.h.
869 Make a few private functions 'static' in unix.c. This prevents
870 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
872 For ZOOM connection, the options targetImplementation{Id,Name,Version}
873 are set when Init Response is received.
875 New function ZOOM_connection_error_x similar to ZOOM_connection_error
876 but returns diagnostic set as well.
878 New function yaz_strerror which is a portable wrapper for
879 strerror/strerror_r/GetLastMessage.
881 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
882 is returned for MARC. If type is "oai", then OAI MARC is returned.
884 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
889 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
891 Fix bad race conditions on SIGTERM and terminate gracefully in
894 Move retrieval (data1) module to Zebra since nobody seems to be
897 Add GRS-1 render for ZOOM using same format as yaz-client.
901 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
903 Fix broken ESpec handling in data1 module.
905 SGML reader parses comments and makes them part of the data1 tree.
907 Added several type casts so that YAZ compiles as C++ code.
909 ZOOM didn't handle PDU encoding failures properly.
911 Added more Bib-1 diagnostics (approved extensions).
913 GNU configure: better check for iconv.
915 More portable use of accept, getpeername. Check for socklen_t. Use
916 int/size_t if socklen_t is not defined.
920 PQF parser rejects bad queries - including those with extra
921 characters in them. PQF parser used to silently ignore that.
922 Cleaner API for PQF added, which allows you to get detailed
923 error information for bad queries (see yaz/pquery.h).
925 Fixed bug in ZOOM_record_get for type "database".
927 Implemented mini iconv library supporting conversions between
928 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
930 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
934 Fixed ZOOM C record cache so that preferredRecordSyntax and
935 elementSetName is used to check for already fetched records.
939 Added three members in bend_initrequest structure to facilitate
940 character set negotiation.
942 Fixed a bug in frontend server that could cause indefinite
943 loops under rare conditions.
945 Revised character set utilities (charneg.h) so that encoding
946 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
948 For PQF, directive @term <type> sets term type for Scan/Search.
949 Here <type> is general, string, numeric, null. The term type
950 is inherited - just like @attr.
952 New call odr_set_charset that sets character set conversion for
953 international-strings on a ODR stream. Prototype is:
954 int odr_set_charset(ODR o, const char *to, const char *from);
955 The InternationalString is still represented as C string in YAZ
956 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
957 won't). On the protocol level, you can use any encoding.
959 Support for UNIX sockets in ZOOM.
961 Solaris recv sometimes returns errno == ENOENT. It is treated as
962 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
964 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
965 both client and server. Code by Morten Bøgeskov.
969 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
970 that they can be used directly from Visual Basic. You must recompile
971 your windows APP if you're using ZOOM.
973 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
974 Commands "lang" and "charset" sets language and character set respectively.
975 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
976 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
978 Attributes from multiple CCL fields may be OR'ed rather than merged
979 using directive "@field or". Fields are still merged by default -
980 equivalent to "@field merge".
982 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
985 Fixed bug in zget for parameter ExtendedServicesResponse.
991 Added PQF feature: '@attr type=value' may be written as '@type=value'.
993 Client displays USR.1:SearchResult-1 (hits per term).
995 Additional Search Info for search in Generic Frontend Server.
997 Fixed CCL parsing of "field=s".
999 WIN32 installer - using the excellent NSIS software from nullsoft.
1001 Fixed CCL parsing of "field = - <number>".
1003 Added function yaz_marc_decode that decodes MARC for line mode
1004 display or XML (similar to that used by JZKit).
1006 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1007 Z39.50. But ISO/ILL was, however.
1009 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1010 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1012 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1013 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1015 --- 1.8.5 2002/02/03
1017 New YAZ client features: Command completion and new commands:
1018 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1019 Code provided by Jacob Poulsen.
1021 New call oid_trav, that visits all registered OIDs via callback.
1023 Function ZOOM_record_get now returns const char pointer rather than
1024 void pointer. It saves a lot of type casts.
1026 For YAZ client, command "auth" now allows you to set authentication
1027 in IdPass style. It is enabled when three tokens are given - order
1028 is user, group and password.
1030 Fix memory leaks in MARC record handling for ZOOM.
1032 New option for YAZ client, -k <kilobytes> that sets
1033 maximum record size. Similar to -k option for generic frontend
1034 server and yaz-ztest.
1036 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1038 Prefix query parser reports "fail" when bad attribute set is given.
1040 Fix in MARC decoder. Proximity logging. Fix for attribute set
1041 in scan handler for server. Patches by Shigeru Ishida.
1043 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1046 Configure option --with-openssl=<dir> now works when a directory is
1047 specified. Patch provided by Morten Bøgeskov.
1049 New option for YAZ client, -u <auth>, that sets authentication.
1051 ZOOM fix: error information was sometimes "missing", since error
1052 was cleared/reset too when it shouldn't.
1054 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1056 --- 1.8.4 2002/01/04
1058 Scan for ZOOM API. New object ZOOM_scanset. New functions
1059 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1060 ZOOM_scanset_destroy.
1062 New ZOOM function, ZOOM_connection_last_event, that returns type
1063 of last event (such as "receive data", "send data", "apdu received",
1066 New ZOOM option, schema, that specifies schema for retrieval.
1068 New CCL feature. Qualifiers can be aliases for one or more
1069 other qualifiers (if more than one is given, OR is used).
1071 ZOOM uses named result sets if target supports it.
1073 Two new YAZ client commands: . (dot, which sources a script of YAZ
1074 client commands), and ! (to execute shell command.). Implemented
1077 Working on Debian packages.
1079 --- 1.8.3 2001/11/19
1081 YAZ client enables named result sets only if target supports it.
1083 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1085 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1086 with key="host" to get same result.
1088 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1089 Function Z3950_resultset_record(s) returns references to records
1090 "owned" by resultset. To become owner use Z3950_record_clone.
1092 Function z_ext_record handles Extended Services. Thanks to
1095 --- 1.8.2 2001/11/12
1097 CCL Parser fix: ignore token comma when dealing with and-lists.
1099 Documentation updates for COMSTACK.
1101 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1102 Changed prototype Z3950_records. For some functions, int parameters
1103 were changed to size_t.
1105 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1108 New MARC decode/display function, marc_display_exl, which properly rejects
1109 non-ISO2709 records. YAZ client uses it.
1111 --- 1.8.1 2001/10/29
1113 Fix bug: local attribute set wasn't set correctly in PQF strings.
1117 * Old Z39.50 codecs no longer supported.
1119 Added ZOOM C binding. See http://zoom.z3950.org/
1121 Renamed states for COMSTACKs to avoid confusion with events.
1123 Implemented cs_look and proper cs_rcvconnect.
1125 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1127 Configure detects POSIX threads on OpenBSD.
1129 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1130 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1132 When error is returned from present handler, non-surrogate diagnostic
1133 is returned in present response (and fetch handler is no longer called).
1135 * Minor adjustments to pquery parser (PQF). Token characters may be
1136 escaped by using backslash (C-style).
1138 PQF parser allows string attribute values to be specified. For @attr,
1139 non-numeric characters after the equal-sign are treated as strings
1140 (e.g. @attr 9=title).
1142 CCL trunction character may be defined (@truncation in file)
1144 * function zget_ExtendedServicesRequest sets waitAction to
1145 waitIfPossible (was wait).
1147 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1150 CCL operator names may be set in field definition files (CCL_bibset).
1151 See ccl/bib1 for an example.
1153 Fixes in ASN.1 compiler for C++ compatibility.
1155 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1156 and "op_or" to avoid conflict with C++.
1158 Fixed problem with GNU readline detection on Redhat 7.0.
1160 Added step-size for Scan backend handler.
1162 Fixed bug that made the frontend server crash when no attribute
1163 set was specified for scan.
1165 Front-end server automatically switches to original working directory
1166 when installed as an NT service. Previously -w had to be specified to
1169 Added extended attributes for retrieval module (data1), so that data1
1170 records carry d1_readXML/SGML attributes. d1_read also supports
1171 null-data rules ( <tag/>)
1173 On UNIX when POSIX threads are available, a separate library libyazthread
1174 is created. Programmers should link with that library and the yaz library
1175 when using threads. The reason for the split was that some applications
1176 on Linux, such as Apache, doesn't work well when using shared objects that
1179 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1180 (or any frontend server) in SSL mode by specifying ssl: followed by
1181 address. Only tested on UNIX.
1183 Added feature for CCL module. Virtual structure s=al or s=ol generates
1184 and-list and or-list respectively instead of phrase search.
1188 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1189 log_mask_str. This was done to avoid name conflicts with other libraries
1190 (such as other PHP extensions).
1192 Added raw OID member for preferred record syntax (request_format_raw)
1193 and returned record syntax (output_format_raw) for backend fetch method.
1195 Config file yaz-config now accepts options so that it returns specific
1196 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1198 Shared library support for UNIX using GNU libtool.
1200 * Modified backend interface. Request/Response struct's replaced by
1201 one read/write C struct. For example bend_fetchrequest and
1202 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1203 Every handler - even search has to be registered in bend_init
1204 handler. This means that the YAZ library no longer refers to
1205 external functions and it makes it possible to make the whole
1206 thing a single DLL/SO.
1208 Added Segment handler for backend server.
1210 Added Zmbol/Zebra administrative functions to YAZ client.
1212 Threaded frontend server on UNIX (when POSIX Threads are available).
1213 Starting the server with option -T enables multi-threading.
1217 Added configure option --enable-comp/disable-comp to control use
1218 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1219 located in sub directory asn.
1221 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1222 in ${exec_prefix}/bin along with the other programs yaz-client and
1225 GNU automake used to maintain makefiles.
1227 Added several OID's.
1229 Changed retrieval module so that we can load records with no abstract
1230 syntax defined. Tagpaths in these records are fully composed of string
1233 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1237 On UNIX, the generated makefile now supports a proper 'make install'.
1238 The prefix can be set via GNU configure to set the install location
1239 (default is /usr/local).
1241 * YAZ programs client and ztest were renamed to yaz-client and
1242 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1243 locations, such as /usr/bin,/usr/local/bin,etc.
1245 * YAZ Header files were moved from include to include/yaz. YAZ Header
1246 files are referred to as include <yaz/log.h> rather than <log.h>.
1247 The YAZ include path (-I ..) is therefore the same as before. Programmers
1248 should update their #include statements or use -Ipath/include/yaz
1249 instead. The main motivation for doing this change is that YAZ header files
1250 can be installed in "standard" locations /usr/include,/usr/local/include
1251 without introducing conflicts, since ALL YAZ header files are stored
1252 in subdirectory yaz (under /usr/include for example).
1254 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1255 rather than project/workspace files. We switched because project files
1256 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1259 Changed name of logging function, logf, to yaz_log, to prevent name
1260 clash with some math-log functions. The YAZ header log.h defines logf
1261 to yaz_log (#define) so there should be no incompatibilities by this
1264 Added bend_start/bend_stop handlers for server. These handler are
1265 called on start/stop of server. For windows they are called whenever
1266 a service is started/stopped.
1268 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1269 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1270 in util/yc.tcl. The auto-generated C code structures are, in a few
1271 cases, incompatible with the old decoders. There are differences in the
1272 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1273 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1274 The preprocessor variable ASN_COMPILED is defined when the compiled
1275 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1276 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1277 wish to use the old encoders/decoders you can specify --disable-yc
1280 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1281 version so that it supports both new - and old version of DB Update
1283 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1284 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1285 change. The name parameter can be set to 0 in which no name is specified
1286 for the construction. The macros odr_implicit and odr_explicit sets name
1287 parameter to zero for the construction involved. New macros
1288 odr_implicit_tag and odr_explicit_tag are similar to the others,
1289 except that a name parameter is added. For programmers' that don't use
1290 ODR they probably only need to change the call to z_APDU and z_External.
1292 Added access control facility by interfacing the TCP wrapper library.
1293 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1294 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1295 name of the daemon and enables the access control as specified in
1296 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1298 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1299 den Dool <H.M.vdnDool@kub.nl>.
1301 Added reference ID parameter to most functions in server API - refer
1302 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1304 Changed name of ccl library to libccl.a (was ccl.a).
1306 Fixed bug in decoder for Explain (Category TargetInfo).
1308 Added support for GNU readline in client. Thanks to Jacob Poulsen
1309 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1311 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1312 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1313 IMPLEMENTATION! This change was made to the development version before
1314 the ZIG decided to retract the amendment. If any users MUST be
1315 compatible with the original Update definition, PLEASE CONTACT US, and
1316 we will include a separate definition corresponding to the old Update
1317 ES. Note that because of the change to the ASN.1 of the
1318 TaskPackageRecordStructure we cannot define a single structure that
1319 will support both versions.
1321 * Added const modifier to buffer parameter for some ODR/BER encoding
1322 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1323 completeWAIS, odr_dumpBER.
1325 Fixed bug in client.c which caused a crash when a scanResponse didn't
1326 contain positionOfTerm.
1328 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1329 * will cause an error in a client if a non-YAZ target sends both a
1330 * list of Scan entries and non-surrogate diagnostics.
1332 Retrieval module enhancements. Tag sets may be typed in the reference
1333 to it. From the .abs-file the "tagset" directive takes a third optional
1334 integer type for the tag set referenced. From a .tag-file the "include"
1335 directive takes a third optional type as well. The old "type" directive
1336 in the tag set itself is still recognized but acts as the default type
1339 Backend interface change. Individual Scan terms returned from bend_scan
1340 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1341 in include/backend.h.
1343 Retrieval module enhancements. Multiple tag sets and attribute sets may
1344 be specified in abstract syntax specs. Revised the error/warning for
1345 logging messages reported by the retrieval module when reading the
1348 Object Identifier system (oid_..) changed. The API is backwards
1349 compatible but the oid-routines now allocates new OID's when needed.
1350 Raw OID's may be specified in oid_getvalbyname.
1352 YAZ now uses GNU configure to generate Makefile(s).
1354 * Minor changes in some of the member names of DeleteResultSetRequest and
1355 DeleteResultSetResponse. See include/proto.h.
1357 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1358 and added member 'languages' in TargetInfo (which was missing).
1360 Changed the way attribute sets are handled in the retrieval
1361 module. These are now cached, just like the abstract syntaxes
1364 Changed YAZ so that it links with compiled ASN.1.
1366 Added Explain-schema definitions and mapping routines. The following
1367 Explain categories have been implemented: AttributeDetails,
1368 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1370 Fixed minor bug in Windows version of Server Library.
1372 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1374 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1376 Added EXTERNAL: UNIverse Resource Report (non-standard).
1378 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1379 ENUMERATED and SET OF.
1381 * Added 'const' to some of the char pointer arguments for the
1382 functions, data1_read_node, data1_getelementbytagname,
1383 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1386 Fixed bug in data1_insert_taggeddata - the last_child member of
1387 parent wasn't initialised.
1389 * Changed data1_read_record and data1_read_node so that the supplied
1390 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1391 doesn't refer to any parts of the "SGML"-buffer.
1393 Fixed bug in server library (Windows version of statserv_remove).
1395 * Changed code so that it compiles as C++. The type definition
1396 of Odr_fun which is a member of Odr_arm was changed. The result is,
1397 that an explicit typecast is needed for the fun pointer when
1398 using Odr_arm - as in:
1399 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1401 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1403 Implemented the new structured date and time definition as approved
1404 by the ZIG. Added schemaId element to the specificTag in Espec-1
1405 (also approved at the last ZIG). Thanks to RVDM.
1407 Added some Object identifiers (RVDM).
1409 Changed the Update Extended Service (RVDM).
1411 Added command "refid" to client which specifies referenceId for
1412 the following requests.
1414 Implemented extended service handling for server. See ztest.c
1415 for an example as well as backend.h. New handlers are registerd
1416 in the Init handler.
1418 * Changed interface for sort in server.
1420 Added new members to statserv_options_block. It allows a server
1421 to read options from another source than just the command line. Thanks
1422 to Charles Woodfield.
1424 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1425 renamed to zboolean. Some C++ compilers complained about the name.
1427 Minor changes to gils.abs. Added index 's' (sort) on title
1428 and date/time-last-modified.
1430 --- 1.4pl2 1998/1/30
1432 Fixed bug in server library regarding inetd mode (-i). This bug
1433 was introduced by release 1.4.
1435 --- 1.4pl1 1998/1/29
1437 Added sort facility in client and backend server interface.
1439 Fixed problem with dependencies in Makefile(s).
1441 Fixed bugs for encoders/decoders of extended services and
1444 Implemented sub-tree feature for schemas. Sub-trees are
1445 referenced in *.abs-files. See explain.abs for an example
1446 of the use of this feature.
1448 Modified bib1.att; local attributes for ANY didn't include
1449 ANY itself (only affects use of the retrieval module).
1451 Fixed bug in plain SGML reader in function data1_read_node:
1452 tags with prefix "var" was incorrectly interpreted as variants.
1454 Added feature "sub-schemas" to enable references to - and definitions
1455 of - group of elements.
1457 * Removed member parent from type data1_element (in data1.h).
1459 Implemented function odr_nullval() that returns the value of
1462 * Removed member num_children from data1_node (in data1.h).
1464 Made NT service interface part of the server library. The
1465 function statserv_main uses the NT service when required and
1466 calls the statserv_start / statserv_close routines.
1468 Routine zget_SearchRequest and zget_PresentRequest fills
1469 resultSetName/Id member with "default" instead of "Default".
1471 Fixed memory leak in server. Request queue member wasn't freed.
1473 Fixed nmem_exit so that memory is freed.
1477 Revised the CCL parser utility to be thread safe.
1479 Added function, oid_ent_to_oid, to replace the function
1480 oid_getoidbyent, which is not thread safe.
1482 * Added nmem_init and nmem_exit to initialize and release
1483 NMEM resources. Function nmem_init should be called once in the
1484 initial thread before NMEM/ODR is used. statserv.c and client.c
1485 have been changed accordingly. The change was necessary to make
1486 NMEM thread safe. The NMEM memory pool is shared amongst threads
1487 in a process. Unix-based applications will still work fine without
1490 Added NT Services interface for the the Z39.50 (statserv) Server.
1491 Refer to the ztest.c source on the usage.
1493 Windows 95/NT port using MSVC5.0. Project files are included in the
1496 * Defined new 'global' handle for the retrieval (data1) system. The
1497 new handled, data1_handle, describes the state of the data1 system.
1498 This handle is passed as first argument to virtually all
1499 data1 related routines. The functions data1_create and data1_destroy
1500 creates and destroys a data1 handle respectively.
1502 Added ODR encode stream member to all backend request structures
1503 init, search, scan etc. This stream should be used to allocate all
1504 memory used for the response when thread safe operation is needed.
1506 Changed the comstack utility, cs_addstr, to be thread safe. The
1507 returned hostname string returned by the function is now part the
1510 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1511 function. The cs_straddr takes a COMSTACK handle as argument, so this
1512 function must be used after cs_create and before bind/connect.
1513 This function is thread safe.
1515 Moved test server to 'ztest' directory - generic server code still
1516 in 'server' directory.
1518 Made prefix query (pquery.c) utility thread safe.
1520 Added new function modifier YAZ_EXPORT to 'export' public DLL
1521 functions when using windows (see include/yconfig.h).
1523 Added definitions to the OID database (util/oid.c) (RVDM).
1525 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1527 Added call to ccl_rpn_delete in client program.
1529 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1530 release of RPN structure.
1532 Added support for C++, headers uses extern "C" for public definitions.
1533 With input from RVDM.
1535 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1536 Thanks to Ronald van der Meer (RVDM).
1538 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1540 Added support for private extensions to the OID database
1541 (oid_setprivateoids()). Thanks to RVDM.
1543 Added optional, physical ANY (key replication)
1545 Fixed null-reference problem in GRS-1 output filter.
1547 Proximity operator added to Prefix Query Format (PQF).
1549 In test client command "base" accepts multiple databases.
1551 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1555 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1557 Smallish bug-fixes in the new encoders/decoders (explain).
1559 Bug fixed in DeleteRequest.
1561 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1563 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1565 Added SOIF syntax (using private OID for now) to retrieval module and client.
1567 Added Update extended service.
1569 Added SearchResult-1 additional info structure.
1571 Added optional CCL (ISO8777) interpreter as separate module. Available
1574 --- 1.2 1996/6/10 (1st anniversary release)
1576 Added Summary record syntax. Lightly tested.
1578 Added OPAC record syntax. Untested.
1580 Added ResourceReport service encoders/decoders. Untested.
1582 Fixed bug in z_Unit - wrong tagging on unitSystem.
1584 Fixed bug in the DiagRecs decoder.
1586 Added options for max PDU size and session timeout to frontend-server.
1588 Added documentation of query-language parsers and other supporting utilities.
1590 [frontend-server] Added Attribute set to the bend_scanrequest API.
1592 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1593 surrogate diagnostics were generated.
1595 [retrieval] Allow multiple local values for attribute.
1597 [retrieval] Allow multiple attributes per element in .abs files. index type.
1599 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1601 --- 1.1pl2 1996/4/10
1603 Minor changes, mostly specific to Zebra's requirements (retrieval)
1607 Repaired bug in frontend server when running multiple listening
1608 endpoints in dynamic mode.
1610 z_External() now won't break if a known, ASN.1 value comes encapsulated
1611 in an octet-string. The value will pass through unmodified in an Odr_oct.
1613 Added a bit of code to the demo client to decode & display
1614 ASN.1-structured records represented in the octet-aligned branch of
1615 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1617 Added z_ext_getentbyref() to the ASN module. Doc updated.
1619 * Completed the SCAN definition in the ASN module. This may break SCAN
1620 code based on older YAZ-versions at compile-time. The fix is easy -
1623 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1624 under the SCAN definition. Remember to initialize this, server-people.
1626 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1627 that this does not extend to ODR and ASN.
1629 Comstack allows insertion of established socket (primarily for
1630 inetd-operation of servers). Doc updated.
1632 Front-end server can now start from the inetd in TCP mode. Doc
1635 --- 1.0pl4 1996/1/24
1639 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1640 the rank and record number.
1642 Adjustments to the frontend server.
1644 Fixed diagnostic BER dumper. It ignored the file argument.
1648 Various changes to retrieval module.
1650 Changed the union discriminators of the protocol files from enums to
1651 ints paired with #defines.
1653 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1656 *Changed operator in the RPN structure to 'roperator', again to avoid a
1659 Fixed problems in Explain decoders/encoders.
1661 --- 1.0pl2 1995/12/6
1663 Memory bug in log module fixed.
1665 --- 1.0pl1 1995/12/5
1667 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1669 Bug in Explain DatabaseInfo module fixed.
1671 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1675 The shift to v1.0 signals that we now consider the *core* functionality
1676 of YAZ reasonably stable (the core being more or less equivalent to
1677 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1678 tested (Explain not at all - though that will happen soonish).
1680 Minor changes to code to support Windows port.
1682 Various minor changes after we're getting to use GRS-1 & co. more.
1684 Added Espec-1 format.
1686 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1687 of the protocol and it cannot be selected when encoding (maps into 'string'
1688 when decoding). Needed to talk to some servers.
1690 Demo client can request simple element set names.
1692 Added Diagnostic Format encoders/decoders.
1694 Added simple Close handling to frontend server (no hooks for resource
1695 reporting yet), and demonstration client.
1697 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1699 --- 1.0b3 1995/08/24
1701 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1702 handled incorrectly when records were requested in the searchResponse. This
1703 will only affect you if you use the frontend-server.
1705 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1706 Test-client will ask for and print GRS1. Ztest will return dummy records
1709 Added Explain encoders/decoders to the service-level API. Untested.
1711 Added Extended Services: Item Order encoders and decoders to the Service-
1712 level API. Untested. We could use a recent copy of the pertinent bits
1713 of the ILL protocol to add those bits.
1715 Added diagnostic format 1 encoders/decoders to the service-level API.
1718 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1719 odr_cons.c, which causes a more correct output.
1721 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1722 was always set to 0 when no records were requested in the searchRequest.
1724 * Added better external-handling. This shouldn't harm old code that
1725 *encodes* externals. It can break code that looks for a
1726 'single-ASN1-type' representation, since those types that are known
1727 are now decoded immediately. Look at the SUTRS sample code in
1728 seshigh.c and client.c. Documentation updated.
1730 Handling of structured records in bend_fetchresponse. Length -1 marks
1731 structured record, type is deduced from format field.
1733 --- 1.0b2 1995/06/27
1734 Fairly quick maintenance release to add SUTRS support.
1736 Fixed handling of SUTRS records in the demonstration client.
1738 * Added format field to the bend_fetchrequest and bend_fetchresponce
1739 structures of the backend API (frontend server). When the record is
1740 returned, the value of the format field is mapped to an OID. The
1741 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1742 of the record. The special value VAL_NONE in the bend_request means
1743 that no specific format was requested by the client. Documentation
1744 updated accordingly. Test server (ztest) will return a fixed dummy
1745 SUTRS record if your client requests SUTRS.
1747 Documentation updated accordingly.
1749 You can now set external libraries and RANLIB support in the top-level
1753 First public release.
