1 Documentation for YAZ is now based on the Docbook XML/XSLT using
2 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
3 is no longer depending on jade/openjade or docbook-to-man scripts.
4 PDF is no longer part of the distribution - but can optionally be
5 made using DSSSL/jadetex or FOP.
7 Added retrieval handling support in Generic Frontend Server to support
8 conversion between MARC/XML as well as XSLTtransforms. See
9 etc/yazgfs.xml for an example.
11 Added Authentication support to Generic Frontend Server in SRU
12 mode. Authentication using HTTP Basic is supported, as is the use
13 of 'x-username' and 'x-password' parameters in the request itself.
15 Added support for a new character set MARC8s identical to MARC8 except
16 that it converts combined characters to single Unicode characters in the
17 Latin-1 range (when possible).
21 ASN.1 compiler 0.4: generates brief Doxygen file header for
22 generated .h/.c files.
24 Utility yaz_iconv now supports conversion to MARC-8.
26 New facilities for the MARC module. The reading - and writing of
27 content are separate methods for the yaz_marc_t handle. The following
28 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
29 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
30 format). Write functions have prefix yaz_marc_write_.. The existing
31 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
32 available. Removed support for OAI-MARC and simplexml (not the
35 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
36 to be returned for this connection.
40 Allow multiple languages and charsets to be specified with
41 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
42 negcharset iso-8859-1,utf-8
44 Translation of proximity nodes from CQL into PQF now works.
46 Moved to automake 1.8, 1.9.
48 Added function yaz_log_set_handler which allows a log handler to be
49 installed. This handler will be called for all log messages. Output
50 to file is also produced; but that can be disabled by passing NULL
51 fname to yaz_log_init_file.
53 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
55 For SRW (including GFS), accept application/soap+xml as content-type
58 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
59 produces NO stylesheet reference even if a default stylesheet is specified
64 Updated Windows package to include yazd.dll + yazd.lib for the
65 Development component.
67 If the environment variable YAZ_LOG is set, then it is used as a
68 string indicating the default level of logging to use if not
69 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
70 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
71 used as before. So, for example, to omit warnings from YAZ logging,
74 cql_transform() now map structure and other attributes before indexes,
75 so that index-specific structures and other attributes can override
76 defaults. So now a combination of mapping specifications such as:
78 index.dc.date = 1=date-modified 4=5
81 cql_transform() now also respects the "always" mapping specification,
82 which establishes an initial set of attributes to be used for all
83 terms except where overridden by more specific attributes associated
84 with the index, relation or modifier.
86 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
87 which mode to use; one of "post", "get" or "soap" (SRW, default).
89 Fixes for yaz_iconv routines: changed trie-based character set conversions
90 to use only non-negative values for bit fields due to Sun's C compiler not
91 supporting negative values.
93 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
94 sequences where not read correctly. Fix by Rustam Usmanov.
96 Updated win/makefile to use options, settings which makes things
97 compile with VS C 2005.
101 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
103 In ZOOM socket code, use select instead of poll on MacOSX.
105 ZOOM-C now support client-side compilation of CQL into RPN that is
106 sent to the server, enabling CQL to be used against all Z39.50
107 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
108 ZOOM_query object, and submit it using ZOOM_connection_search().
109 The CQL-to-RPN translation uses a configuration file, the name of
110 which must be specified in the Connection's "cqlfile" option.
112 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
113 function, which takes as its start-term parameter a ZOOM_query object
114 (which may have had either CQL or RPN set into it).
117 --- 2.1.10 2005/11/29
119 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
120 GFS to support this as well. Backend handler, bend_srw_update, does the
121 update work. Code contributed by Ko van der Sloot.
123 Allow retrieval of Search Result-1 information in ZOOM by the use of
124 options that are attached to a result set. ZOOM documentation updated
127 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
128 UTF-8 conversion. Patch by Raj Patel.
130 Added option -m to GFS to control formatting of timestamps in log file.
132 Added 'exit' as synonym for 'quit' in yaz-client
134 Added support for specifying SRW resultSetId + resultSetIdleTime in a
135 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
136 for the new members. Patch by Ko van der Sloot.
138 Added support for SRU POST. It is supported for content-type
139 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
141 Do not build the separate Multi-threaded (MT) library libyazthread.la.
142 Instead make the library libyaz.la multi-threaded. Threading as a whole
143 can still be disabled by configure option --disable-threads. Previosly,
144 with older GLIBCs there were problems with MT libs under Apache. This
145 has now been fixed a long time ago.
147 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
150 CQL module modified to be case insensitive for relations/indexes/operations.
152 Fixed bug in CQL transform code: incorrect value relationModifieder
155 Added 'show all' command for yaz-client which retrieves all results
158 Added new yaz-client, xmles, which takes a (private) OID and
159 a document to be sent as an extended service request.
161 Describe new yaz-client commands wait_response and set_auto_wait.
163 Increase TCP/IP listener backlog from 3 (which I am guessing was
164 copied from the SunOS manual entry way back when) so SOMAXCONN, so
165 that the socket will queue as many incoming connections as it's able
166 to handle ongoing connections. In other words, it will never now
167 refuse a connection that it would be able to handle merely because
168 it's not got around to accepting() enough of the pending connections
169 yet. This is the behaviour anyway under Linux, where the listen()
170 argument is ignored; but not under BSD and on systems such as
171 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
172 YAZ-based servers should now be uniform across operating systems in
175 yaz-marcdump uses 64-bit file access on some systems. This is enabled
176 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
177 This allows yaz-marcdump to read large MARC batches (>2 GB).
179 Modified all YAZ source files - except the source which is auto-generated
180 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
183 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
184 corresponding to the existing *_setl() function. These allow option
185 values containing arbitrary valuues.
187 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
188 ZOOM_resultset_sort() in new applications. Its behaviour is identical
189 except that it returns an indicator of whether or not the sort
190 criterion was accepted (0 for OK, -1 for invalid).
194 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
195 MARC output rather than returning "new" buffer.
197 yaz-client warns about unknown init options.
199 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
203 Added support for SRW sort in Generic Frontend Server. Patch
204 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
205 sortKeys - or NULL if none is provided.
207 Fixed bug #307: It was impossible to specify indefinite/no timeout
208 for ZOOM_event. Special timeout value -1 now means indefinite timeout
211 Added support for multiple languages and charsets to be specified in
212 ZOOM. Each charset/language is separated by a blank. If negotiation is
213 in effect in init-response, Option
214 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
215 Code based on patch by Vasiliy Osadchuk.
217 Fixed bug #306: infinite recursion that occurred when calling
218 yaz_log_level_init as the first call (before other log level or
221 Fixed bug in scan handling in front end server: if preferred-Position-In-
222 Response was non-present, a NULL pointer referece was performed.
226 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
227 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
228 now defined for all those error codes. So instead of putting 109 in
229 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
230 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
232 Modified the yaz-marcdump utility to skip garbage bytes between MARC
235 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
237 Program yaz-client now exits and produces an error message if multiple
238 Z39.50 servers are specified on the command line (none or one allowed
241 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
246 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
248 Fixed bug #272: Preserve spacing for CCL terms.
252 Added support for virtual hosts and multiple backend servers for
253 the YAZ frontend server. The configution is XML based and
254 support specificition of CQL to RPN mappings and explain information.
255 See section "Virtual Hosts" in the YAZ manual.
257 Extended OPAC display utility. OPAC display utility renders
258 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
259 to supplement yaz_marc_decode_wrbuf.
261 Fixed a bug in MARC decoder that could caused it to crash for some
262 invalid MARC records. More diagnostics and warnings where added in
263 XML output (warnings, etc are stored in comments).
265 --- 2.0.34 2005/02/08
267 Fixes for UNIX domain sockets. Bug #261.
269 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
271 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
272 Added yaz_marc_subfield_str which defines subfield lead string which is
273 used in YAZ_MARC_LINE format. Default string is blank+$. Added
274 yaz_marc_endline_str which defines end of fields string used in
275 YAZ_MARC_LINE format. Default string is newline.
277 Experimental support for MarcXChange. This format can be produced
278 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
279 http://www.bs.dk/standards/MarcXchange.xsd
281 Added yaz-client commands scansize that sets maximum number of
282 entries to be returned by scan.
284 --- 2.0.32 2005/01/11
286 Added support for SRW scan in yaz-client and Generic Frontend Server.
288 * Added whereInList member to SRW Scan Term.
290 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
292 Fixed NMEM system to return aligned blocks on the smallest boundaries
293 that are suitably aligned for all possible types on the particular
294 architecture YAZ is being built for.
296 --- 2.0.30 2005/01/04
298 Fixed numerious warnings that was issued with newer versions of GCC.
300 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
301 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
304 Make YAZ Generic Frontend Server slightly faster.
306 Enhance (and reduce) logging for Generic Frontend Server.
308 Revert YAZ log system so that it flushes every write operation
309 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
311 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
312 instead of LOG_, due to name clash with syslog(3). LOG_ are still
313 present. New applications should define YAZ_USE_NEW_LOG=1 - this
314 will effectively disable old definitions.
316 --- 2.0.28 2004/11/09
318 Added yaz_log_time_format which specifies log format using
321 Added yaz_log_module_level which returns mask for a module. Value
322 is non-zero mask a if module is enabled; zero if disabled.
324 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
325 in include/yaz/cql.h.
327 Fixed bug #176: Dont throw diagnostics on empty SRU args.
329 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
331 Fixed bug #172: RPM builds does not enable SSL.
333 Doxyfile.in part of dist. Doxyfile generated by configure.
335 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
336 are given and the corresponding component does not exist.
338 Extend CCL documentation in YAZ reference. Describe r=r.
340 --- 2.0.26 2004/10/01
342 Fixed MARC->MARCXML conversion to properly deal with
343 fields, subfields, indicators having non-ASCII characters.
345 Fixed MARC->MARCXML conversion so that ASCII control characters
346 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
349 Added YAZ GFS support for conversion from Z39.50 surrogate
350 diagnostics to SRW surrogate diagnostics.
352 Bug fix: YAZ GFS did not return schema in explainResponse.
354 --- 2.0.25 2004/09/30
356 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
357 now converts recordSchema to elementSetName as well as schema URI.
359 Fixed bug in COMSTACK that prevented HTTP request packages from being
362 --- 2.0.24 2004/09/29
364 Added CCL facility r=r "range" which is similar to r=o "ordered" but
365 does not require white-space before and after the dash in a range, e.g.
366 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
369 Fixed a few AC_TRY_LINK configure tests that did not operate properly
370 due to new GCC removing "redundant" code.
372 Added yaz-client commands scanpos and scanstep that sets preferred
373 position and step-size for scan.
375 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
377 Added CCL utility ccl_qual_buf which parses one or more CCL
378 spec lines in a buffer.
380 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
381 of name and value - ignoring empty lines and comments.
383 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
385 Added odr_get_element_path which returns current element path for an
386 ODR handle. This utility is useful in error handling or user-defined
389 Added ODR_PRINT utility odr_set_stream which is is a more generic
390 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
391 to a write function and pointer to close function. The close function - if
392 non-NULL - will be called during odr_destroy.
394 Fixed bug in CCL parser where truncation char was not removed from
395 right side when truncation=both was in effect.
397 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
400 --- 2.0.23 2004/08/11
402 Fix buffer overrun in CQL parser when dealing with proximity (%).
404 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
405 to UTF-8/UCS conversion is now only based on codetables.xml.
407 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
409 --- 2.0.22 2004/08/06
411 Add support for more "commit changes" in ZOOM (uses Extended Services).
413 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
416 Yet another small fix for configure of SSL.
418 --- 2.0.21 2004/05/14
420 Fix SSL libs for configure when --with-openssl=DIR is given.
422 --- 2.0.20 2004/05/10
424 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
426 SSL comstack now uses yaz.pem certificate file on server side
427 by default. Certificate filename can be configured by calling
428 comstack function cs_set_ssl_certificate_file before cs_bind is used.
430 Fix bug regarding multiple calls to ZOOM_connection_connect.
432 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
434 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
435 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
437 ZOOM now allows inspection of X509 peer certificate for verification.
438 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
440 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
441 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
442 as "modular" but it simplifies things.
444 Added cs_get_peer_certificate to that returns peer X509 PEM.
446 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
447 NULL if SSL is unavailable.
449 Documentation about MARC decoding tools.
451 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
453 --- 2.0.19 2004/03/30
455 Rename CHANGELOG to NEWS to follow GNU style packing.
457 Fix bug with missing initialization of member in init_diagnostics.
458 This bug affects threaded version of GFS server.
460 --- 2.0.18 2004/03/20
462 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
465 Ensure zlib.dll is packed with Windows install.
467 --- 2.0.17 2004/03/17
469 Fix encoding of xsd:string to use text instead of CDATA.
471 Fix endless loop in CQL parser with unbalanced ".
473 Use a more compact way to store MARC-8 conversion tables.
475 --- 2.0.16 2004/03/16 Debian only
477 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
480 Update CQL parser to use new CQL 1.1 modifiers for booleans and
485 --- 2.0.15 2004/03/01
487 Another fix for decoding of XML packed records.
489 --- 2.0.14 2004/02/25
491 Fixes for Chunked encoding. White space not ignored after length spec.
493 Update NS and use default NS for SRW diagnostic elements.
495 --- 2.0.13 2004/02/23
497 Implement ZOOM_resultset_cache_reset which resets record cache.
499 Implement ZOOM_resultset_sort which sorts a result set.
501 Implement chunked HTTP transfer.
503 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
505 --- 2.0.12 2004/02/16
507 Added member 'schema' to bend_explain_rr structure so that backend
508 can specify explain record identifier. Defaults to Zeerex 2.0.
510 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
512 --- 2.0.11 2004/02/16
514 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
517 Added init command for yaz-client which sends "extra" init request.
519 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
520 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
522 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
524 Make ZOOM error code for "invalid query".
526 Fixed compilation for SSL which wasn't properly enabled for all platforms.
528 --- 2.0.10 2004/02/05
530 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
533 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
535 Added option -p <file> to make Generic Frontend Server to write PID file.
537 Added option -D to put Generic Frontend Server in background on its own.
539 Make ZOOM C recognize option "password". If unset, "pass" is used
540 (for backwards compatibility).
542 Fixed a bug in Generic Frontend Server that could make it crash if a
543 client sets characterSetNegotation bit, but didn't pass negotiation stuff
546 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
547 Must be issued before open, in order to be in effect.
549 --- 2.0.9-6 2004/01/12 Debian/Windows
551 Make the SRU server more picky WRT unknown params, etc.
553 Bug fix: ZOOM scan response didn't return displayTerm - when present.
555 New YAZ client command, options, that sets Z39.50 options.
557 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
558 options from a string of tokens (one token for each option bit).
560 Update SRW diagnostic code messages.
562 --- 2.0.9-5 2004/01/07 Debian/Windows
564 Handle user defined stylesheet for SRW/SRU.
566 --- 2.0.9-4 2004/01/06 Debian/Windows
568 Fix bug in decoding of Content-Length.
570 --- 2.0.9-3 2004/01/06 Debian/Windows
572 Fix a bug with decoding of XML packed records.
574 --- 2.0.9-2 2004/01/05 Debian only
576 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
578 Fix bug in SRW/SRU diagnostics decoding.
582 Fixed bug in Generic Frontend Server which could drop records exceeding
583 preferred message size. Reported and fixed by Irina Dijour.
585 Fixed calculation of package size for structured records in Generic
586 Frontend Server. Reported and fixed by Irina Dijour.
588 Fixed namespace for SRW/SRU diagnostics.
590 Fixed SEGV in yaz-client that occured for HTTP connection errors.
594 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
595 this version is incompatible with version 1.0 and older YAZ SRW/SRU
598 CQL changes to reflect recent changes to the specification:
599 * Documentation talks about context sets instead of index sets.
600 * Documentation talks about indexes instead of qualifiers.
601 * The CQL-to-PQF transformer's configuration file now uses
602 "index.set.name = <attributes>" instead of the old form
603 "qualifier.set.name = <attributes>". (Both forms are still
604 understood but the latter is deprecated.)
605 * CQL terms with no explicit index specified are now interpreted as
606 cql.serverChoice instead of srw.serverChoice (which of course
607 behaves exactly the same.)
611 MARC conversion can now generate ISO2709 output in another
612 character set. yaz-marcdump uses this facility if you invoke it
615 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
616 functions from there can be used from C++.
620 Frontend server now transfers memory from decoded packages to stream
623 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
624 references to show up.
626 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
627 the ZOOM Abstract API. The older names for the same options are still
628 also supported for the benefit of old applications.
630 ZOOM-C supports "implementationId" and "implementationVersion" options
631 to go along with "implementationName". These allow the user code to
632 specify identification strings to be sent to servers.
633 Add OID for the new ExtLite attribute set.
635 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
636 as requested/supplid by Ere Maijala <ere@atp.fi>
638 For generic frontend server, reverse the order of
639 "toolkit-supplied / application-supplied" strings sent as implementationId,
640 Name and Version. Also, remove the spaces around the slash. This brings
641 the GFS in line with the behaviour of ZOOM-C on the client side.
643 Add function ZOOM_scanset_display_term.
645 yaz-client shows scan displayTerm if present.
647 Utility yaz-iconv is now installed by default along with the man page
650 Extend configure check for OpenSSL to use pkg-config where available (such
653 Incorporate patch by Morten Bogeskov which allows a Unix file socket
654 server to specify uid/gid/mask for socket using the format
655 unix:[user=uid,][group=gid,][umask=mask,]file=path
656 If file= is omitted the existing format is assumed, e.g.
658 in which case the mask is 0666 (rw for everybody).
660 Major restructure of YAZ source. All source in libyaz is in src directory.
661 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
662 util (utility programs such as ASN.1 compiler, yaz-marcdump).
664 Added man page for utility yaz-marcdump (used to be called marcdump).
665 yaz-marcdump is installed by 'make install'.
667 Fixed a memory leak in Generic Frontend Server that occurred when decoding
668 of incoming package failed.
670 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
672 Change prototype of odr_perror: add const to message string.
674 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
676 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
677 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
678 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
679 DNS lookup. There should not be any compatibility problems with this
680 assuming that blocking=1 or 0 is used.
682 Fix bad reference in UNIX comstack in function cs_addrstr.
684 Fix for compilation on AIX.
686 The generic front-end server (server/seshigh.c) now supports returning
687 Init diagnostics to the client in User-information-field, in
688 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
693 Allow any CQL relation (not just all,any,exact,scr).
695 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
696 that features the same UI.
698 Implemented command update0 in YAZ client which is equivalent to
699 update but uses old of Ext Update ASN.1.
701 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
702 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
703 Previously no OID was used for this info.
705 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
706 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
707 returns 'malformed search term' otherwise.
709 SortResponse member resultCount now set to NULL in sort handler of
712 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
715 Add three new utility functions for translating OIDs between various
716 formats -- symbolic name such as "Usmarc", minus-1-terminated int
717 arrays and dotted strings such as "1.2.840.10003.9.5.1":
718 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
719 char *oid_to_dotstring(const int *oid, char *oidbuf);
720 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
722 Reverted modifications for ES Update definition for z_IU0Update
723 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
724 is back to YAZ 2.0.2.
726 String value attributes for CCL parser.
728 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
729 which their FirstSearch server returns in Init responses, sometimes
730 carrying useful diagnostic information when Init fails. This has the
731 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
732 "z39.50/oclcui.asn", where its definition is somewhat different from
733 what OCLC document on their web-site, as required to interoperate with
736 Support for anonymous authentication in yaz-client. Use the command
739 * Fix the OID of the Index Data-local "admin" Extended Service from
740 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
741 the 1000, which indicates a locally-defined OID, was a mistake.
745 Fix CCL directive @case handling so that it affects string match for
746 both CCL keywords and qualifiers.
748 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
749 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
750 Decoder has been updated with ASN.1 changes as listed in
751 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
752 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
753 z_IUUpdate, remains unchanged.
755 ZOOM_record_get may now return a record in a specific character set.
756 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
757 "from" is the character set of record as returned by target. "to" is
758 the character set to be returned. If omitted, "to" is UTF-8.
760 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
762 New ODR utility, odr_getelement, which returns name of element for
763 which encoding/decoding failed.
765 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
766 in cases where a required element was omitted.
768 Bug fix: some MARC8 sequences were not converted.
770 New ZOOM option "step" which specifies number of records to be
771 retrieved in one chunk. Used in conjunction with "start" and "count".
773 SRW support for yaz-client. Use scheme http: to use it, e.g.
776 yaz-client no longer does (un)intelligent character set conversions
777 by default. Can be enabled with charset and marc_charset commands.
779 xmalloc trace fix for 64-bit systems such as DEC alpha.
781 Solaris 2.6 compile fix.
783 New function, cql_strerror() translates SRW error codes, as returned
784 by cql_transform_error(), into human-readable English strings. Used
785 in yaz-client diagnostics when appropriate.
787 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
788 converts it into a type-1 query which is sent to the server. This
789 makes CQL available for use with all Z-servers, as opposed to the tiny
790 minority that can handle CQL queries themselves.
794 New Debian package layout similar to the Redhat Package layout.
796 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
797 and search result respectively.
801 Redhat package is now several packages: libyaz (runtime libraries),
802 libyaz-devel (development and documentation, and yaz (utility programs).
803 Package spec file by Morten Bøgeskov.
805 New member 'schema' in struct bend_fetch_rr which the name of requested
806 schema (SRW/SRU) for record (or NULL if none was given). The fetch
807 handler MAY set this to reflect the schema of the returned record.
809 New member 'display_term' in struct scan_entry. GFS now sets member entries
810 and allocates scan entries to be filled by user scan handler. In previous
811 version, entries member was allocated by the scan handler. That still works,
812 but the GFS will ignore member display_term - assuming it was NOT set by
813 the handler. The fact that the GFS now allocates the entries both allows
814 for new members and makes a scan handler easier to write.
816 Fix CQL lex buffer overflow.
818 SRW/SRU recordPacking. For SRW default recordPacking is string. For
819 SRU default recordPacking is string.
821 SRU protocol support for frontend server.
823 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
825 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
827 Added scan for the ZOOM shell (zoomsh).
831 * String Identifers for Schemas (Amendment 5).
832 http://lcweb.loc.gov/z3950/agency/amend/am5.html
833 Old definition for schema
834 Odr_oid *schema; /* OPT */
839 Z_InternationalString *uri;
840 #define Z_Schema_oid 1
841 #define Z_Schema_uri 2
844 * resultCount parameter to Sort Response (Amendment 1).
845 http://lcweb.loc.gov/z3950/agency/amend/am1.html
847 Support for SRW 1.0 over HTTP. This is an optional feature and
848 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
851 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
852 on the same port. SRW SearchRetrieveRequests are mapped
853 to bend_init,bend_search,bend_fetch,bend_close.
855 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
857 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
858 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
860 ZOOM connections are SRW based if schem http is used for hostname
861 in connect, e.g. z = ZOOM_connection_new("http://myserver");
862 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
864 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
865 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
866 distance=n, order=true/false, relation=le, prox unit=word. If
867 n is omitted, distance 1 is used.
869 Fixed problem with C compiler include path in wrong order.
871 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
872 on Solaris. Patch from Ko van der Sloot.
874 New MARC decode API. All new functions operate on a yaz_marc_t
875 handle. The most important new functions are: yaz_marc_create,
876 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
877 decode and destroy respectively. Decoder can produce formats
878 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
879 include/yaz/marcdisp.h.
881 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
882 to UTF-8, UCS-32, wchar_t or Latin-1.
884 * Prototypes for yaz_iconv_-functions moved to separate header
885 include/yaz/yaz-iconv.h.
887 Make a few private functions 'static' in unix.c. This prevents
888 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
890 For ZOOM connection, the options targetImplementation{Id,Name,Version}
891 are set when Init Response is received.
893 New function ZOOM_connection_error_x similar to ZOOM_connection_error
894 but returns diagnostic set as well.
896 New function yaz_strerror which is a portable wrapper for
897 strerror/strerror_r/GetLastMessage.
899 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
900 is returned for MARC. If type is "oai", then OAI MARC is returned.
902 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
907 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
909 Fix bad race conditions on SIGTERM and terminate gracefully in
912 Move retrieval (data1) module to Zebra since nobody seems to be
915 Add GRS-1 render for ZOOM using same format as yaz-client.
919 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
921 Fix broken ESpec handling in data1 module.
923 SGML reader parses comments and makes them part of the data1 tree.
925 Added several type casts so that YAZ compiles as C++ code.
927 ZOOM didn't handle PDU encoding failures properly.
929 Added more Bib-1 diagnostics (approved extensions).
931 GNU configure: better check for iconv.
933 More portable use of accept, getpeername. Check for socklen_t. Use
934 int/size_t if socklen_t is not defined.
938 PQF parser rejects bad queries - including those with extra
939 characters in them. PQF parser used to silently ignore that.
940 Cleaner API for PQF added, which allows you to get detailed
941 error information for bad queries (see yaz/pquery.h).
943 Fixed bug in ZOOM_record_get for type "database".
945 Implemented mini iconv library supporting conversions between
946 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
948 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
952 Fixed ZOOM C record cache so that preferredRecordSyntax and
953 elementSetName is used to check for already fetched records.
957 Added three members in bend_initrequest structure to facilitate
958 character set negotiation.
960 Fixed a bug in frontend server that could cause indefinite
961 loops under rare conditions.
963 Revised character set utilities (charneg.h) so that encoding
964 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
966 For PQF, directive @term <type> sets term type for Scan/Search.
967 Here <type> is general, string, numeric, null. The term type
968 is inherited - just like @attr.
970 New call odr_set_charset that sets character set conversion for
971 international-strings on a ODR stream. Prototype is:
972 int odr_set_charset(ODR o, const char *to, const char *from);
973 The InternationalString is still represented as C string in YAZ
974 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
975 won't). On the protocol level, you can use any encoding.
977 Support for UNIX sockets in ZOOM.
979 Solaris recv sometimes returns errno == ENOENT. It is treated as
980 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
982 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
983 both client and server. Code by Morten Bøgeskov.
987 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
988 that they can be used directly from Visual Basic. You must recompile
989 your windows APP if you're using ZOOM.
991 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
992 Commands "lang" and "charset" sets language and character set respectively.
993 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
994 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
996 Attributes from multiple CCL fields may be OR'ed rather than merged
997 using directive "@field or". Fields are still merged by default -
998 equivalent to "@field merge".
1000 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1003 Fixed bug in zget for parameter ExtendedServicesResponse.
1007 --- 1.8.6 2002/03/25
1009 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1011 Client displays USR.1:SearchResult-1 (hits per term).
1013 Additional Search Info for search in Generic Frontend Server.
1015 Fixed CCL parsing of "field=s".
1017 WIN32 installer - using the excellent NSIS software from nullsoft.
1019 Fixed CCL parsing of "field = - <number>".
1021 Added function yaz_marc_decode that decodes MARC for line mode
1022 display or XML (similar to that used by JZKit).
1024 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1025 Z39.50. But ISO/ILL was, however.
1027 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1028 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1030 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1031 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1033 --- 1.8.5 2002/02/03
1035 New YAZ client features: Command completion and new commands:
1036 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1037 Code provided by Jacob Poulsen.
1039 New call oid_trav, that visits all registered OIDs via callback.
1041 Function ZOOM_record_get now returns const char pointer rather than
1042 void pointer. It saves a lot of type casts.
1044 For YAZ client, command "auth" now allows you to set authentication
1045 in IdPass style. It is enabled when three tokens are given - order
1046 is user, group and password.
1048 Fix memory leaks in MARC record handling for ZOOM.
1050 New option for YAZ client, -k <kilobytes> that sets
1051 maximum record size. Similar to -k option for generic frontend
1052 server and yaz-ztest.
1054 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1056 Prefix query parser reports "fail" when bad attribute set is given.
1058 Fix in MARC decoder. Proximity logging. Fix for attribute set
1059 in scan handler for server. Patches by Shigeru Ishida.
1061 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1064 Configure option --with-openssl=<dir> now works when a directory is
1065 specified. Patch provided by Morten Bøgeskov.
1067 New option for YAZ client, -u <auth>, that sets authentication.
1069 ZOOM fix: error information was sometimes "missing", since error
1070 was cleared/reset too when it shouldn't.
1072 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1074 --- 1.8.4 2002/01/04
1076 Scan for ZOOM API. New object ZOOM_scanset. New functions
1077 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1078 ZOOM_scanset_destroy.
1080 New ZOOM function, ZOOM_connection_last_event, that returns type
1081 of last event (such as "receive data", "send data", "apdu received",
1084 New ZOOM option, schema, that specifies schema for retrieval.
1086 New CCL feature. Qualifiers can be aliases for one or more
1087 other qualifiers (if more than one is given, OR is used).
1089 ZOOM uses named result sets if target supports it.
1091 Two new YAZ client commands: . (dot, which sources a script of YAZ
1092 client commands), and ! (to execute shell command.). Implemented
1095 Working on Debian packages.
1097 --- 1.8.3 2001/11/19
1099 YAZ client enables named result sets only if target supports it.
1101 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1103 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1104 with key="host" to get same result.
1106 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1107 Function Z3950_resultset_record(s) returns references to records
1108 "owned" by resultset. To become owner use Z3950_record_clone.
1110 Function z_ext_record handles Extended Services. Thanks to
1113 --- 1.8.2 2001/11/12
1115 CCL Parser fix: ignore token comma when dealing with and-lists.
1117 Documentation updates for COMSTACK.
1119 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1120 Changed prototype Z3950_records. For some functions, int parameters
1121 were changed to size_t.
1123 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1126 New MARC decode/display function, marc_display_exl, which properly rejects
1127 non-ISO2709 records. YAZ client uses it.
1129 --- 1.8.1 2001/10/29
1131 Fix bug: local attribute set wasn't set correctly in PQF strings.
1135 * Old Z39.50 codecs no longer supported.
1137 Added ZOOM C binding. See http://zoom.z3950.org/
1139 Renamed states for COMSTACKs to avoid confusion with events.
1141 Implemented cs_look and proper cs_rcvconnect.
1143 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1145 Configure detects POSIX threads on OpenBSD.
1147 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1148 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1150 When error is returned from present handler, non-surrogate diagnostic
1151 is returned in present response (and fetch handler is no longer called).
1153 * Minor adjustments to pquery parser (PQF). Token characters may be
1154 escaped by using backslash (C-style).
1156 PQF parser allows string attribute values to be specified. For @attr,
1157 non-numeric characters after the equal-sign are treated as strings
1158 (e.g. @attr 9=title).
1160 CCL trunction character may be defined (@truncation in file)
1162 * function zget_ExtendedServicesRequest sets waitAction to
1163 waitIfPossible (was wait).
1165 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1168 CCL operator names may be set in field definition files (CCL_bibset).
1169 See ccl/bib1 for an example.
1171 Fixes in ASN.1 compiler for C++ compatibility.
1173 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1174 and "op_or" to avoid conflict with C++.
1176 Fixed problem with GNU readline detection on Redhat 7.0.
1178 Added step-size for Scan backend handler.
1180 Fixed bug that made the frontend server crash when no attribute
1181 set was specified for scan.
1183 Front-end server automatically switches to original working directory
1184 when installed as an NT service. Previously -w had to be specified to
1187 Added extended attributes for retrieval module (data1), so that data1
1188 records carry d1_readXML/SGML attributes. d1_read also supports
1189 null-data rules ( <tag/>)
1191 On UNIX when POSIX threads are available, a separate library libyazthread
1192 is created. Programmers should link with that library and the yaz library
1193 when using threads. The reason for the split was that some applications
1194 on Linux, such as Apache, doesn't work well when using shared objects that
1197 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1198 (or any frontend server) in SSL mode by specifying ssl: followed by
1199 address. Only tested on UNIX.
1201 Added feature for CCL module. Virtual structure s=al or s=ol generates
1202 and-list and or-list respectively instead of phrase search.
1206 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1207 log_mask_str. This was done to avoid name conflicts with other libraries
1208 (such as other PHP extensions).
1210 Added raw OID member for preferred record syntax (request_format_raw)
1211 and returned record syntax (output_format_raw) for backend fetch method.
1213 Config file yaz-config now accepts options so that it returns specific
1214 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1216 Shared library support for UNIX using GNU libtool.
1218 * Modified backend interface. Request/Response struct's replaced by
1219 one read/write C struct. For example bend_fetchrequest and
1220 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1221 Every handler - even search has to be registered in bend_init
1222 handler. This means that the YAZ library no longer refers to
1223 external functions and it makes it possible to make the whole
1224 thing a single DLL/SO.
1226 Added Segment handler for backend server.
1228 Added Zmbol/Zebra administrative functions to YAZ client.
1230 Threaded frontend server on UNIX (when POSIX Threads are available).
1231 Starting the server with option -T enables multi-threading.
1235 Added configure option --enable-comp/disable-comp to control use
1236 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1237 located in sub directory asn.
1239 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1240 in ${exec_prefix}/bin along with the other programs yaz-client and
1243 GNU automake used to maintain makefiles.
1245 Added several OID's.
1247 Changed retrieval module so that we can load records with no abstract
1248 syntax defined. Tagpaths in these records are fully composed of string
1251 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1255 On UNIX, the generated makefile now supports a proper 'make install'.
1256 The prefix can be set via GNU configure to set the install location
1257 (default is /usr/local).
1259 * YAZ programs client and ztest were renamed to yaz-client and
1260 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1261 locations, such as /usr/bin,/usr/local/bin,etc.
1263 * YAZ Header files were moved from include to include/yaz. YAZ Header
1264 files are referred to as include <yaz/log.h> rather than <log.h>.
1265 The YAZ include path (-I ..) is therefore the same as before. Programmers
1266 should update their #include statements or use -Ipath/include/yaz
1267 instead. The main motivation for doing this change is that YAZ header files
1268 can be installed in "standard" locations /usr/include,/usr/local/include
1269 without introducing conflicts, since ALL YAZ header files are stored
1270 in subdirectory yaz (under /usr/include for example).
1272 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1273 rather than project/workspace files. We switched because project files
1274 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1277 Changed name of logging function, logf, to yaz_log, to prevent name
1278 clash with some math-log functions. The YAZ header log.h defines logf
1279 to yaz_log (#define) so there should be no incompatibilities by this
1282 Added bend_start/bend_stop handlers for server. These handler are
1283 called on start/stop of server. For windows they are called whenever
1284 a service is started/stopped.
1286 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1287 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1288 in util/yc.tcl. The auto-generated C code structures are, in a few
1289 cases, incompatible with the old decoders. There are differences in the
1290 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1291 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1292 The preprocessor variable ASN_COMPILED is defined when the compiled
1293 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1294 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1295 wish to use the old encoders/decoders you can specify --disable-yc
1298 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1299 version so that it supports both new - and old version of DB Update
1301 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1302 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1303 change. The name parameter can be set to 0 in which no name is specified
1304 for the construction. The macros odr_implicit and odr_explicit sets name
1305 parameter to zero for the construction involved. New macros
1306 odr_implicit_tag and odr_explicit_tag are similar to the others,
1307 except that a name parameter is added. For programmers' that don't use
1308 ODR they probably only need to change the call to z_APDU and z_External.
1310 Added access control facility by interfacing the TCP wrapper library.
1311 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1312 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1313 name of the daemon and enables the access control as specified in
1314 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1316 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1317 den Dool <H.M.vdnDool@kub.nl>.
1319 Added reference ID parameter to most functions in server API - refer
1320 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1322 Changed name of ccl library to libccl.a (was ccl.a).
1324 Fixed bug in decoder for Explain (Category TargetInfo).
1326 Added support for GNU readline in client. Thanks to Jacob Poulsen
1327 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1329 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1330 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1331 IMPLEMENTATION! This change was made to the development version before
1332 the ZIG decided to retract the amendment. If any users MUST be
1333 compatible with the original Update definition, PLEASE CONTACT US, and
1334 we will include a separate definition corresponding to the old Update
1335 ES. Note that because of the change to the ASN.1 of the
1336 TaskPackageRecordStructure we cannot define a single structure that
1337 will support both versions.
1339 * Added const modifier to buffer parameter for some ODR/BER encoding
1340 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1341 completeWAIS, odr_dumpBER.
1343 Fixed bug in client.c which caused a crash when a scanResponse didn't
1344 contain positionOfTerm.
1346 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1347 * will cause an error in a client if a non-YAZ target sends both a
1348 * list of Scan entries and non-surrogate diagnostics.
1350 Retrieval module enhancements. Tag sets may be typed in the reference
1351 to it. From the .abs-file the "tagset" directive takes a third optional
1352 integer type for the tag set referenced. From a .tag-file the "include"
1353 directive takes a third optional type as well. The old "type" directive
1354 in the tag set itself is still recognized but acts as the default type
1357 Backend interface change. Individual Scan terms returned from bend_scan
1358 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1359 in include/backend.h.
1361 Retrieval module enhancements. Multiple tag sets and attribute sets may
1362 be specified in abstract syntax specs. Revised the error/warning for
1363 logging messages reported by the retrieval module when reading the
1366 Object Identifier system (oid_..) changed. The API is backwards
1367 compatible but the oid-routines now allocates new OID's when needed.
1368 Raw OID's may be specified in oid_getvalbyname.
1370 YAZ now uses GNU configure to generate Makefile(s).
1372 * Minor changes in some of the member names of DeleteResultSetRequest and
1373 DeleteResultSetResponse. See include/proto.h.
1375 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1376 and added member 'languages' in TargetInfo (which was missing).
1378 Changed the way attribute sets are handled in the retrieval
1379 module. These are now cached, just like the abstract syntaxes
1382 Changed YAZ so that it links with compiled ASN.1.
1384 Added Explain-schema definitions and mapping routines. The following
1385 Explain categories have been implemented: AttributeDetails,
1386 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1388 Fixed minor bug in Windows version of Server Library.
1390 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1392 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1394 Added EXTERNAL: UNIverse Resource Report (non-standard).
1396 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1397 ENUMERATED and SET OF.
1399 * Added 'const' to some of the char pointer arguments for the
1400 functions, data1_read_node, data1_getelementbytagname,
1401 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1404 Fixed bug in data1_insert_taggeddata - the last_child member of
1405 parent wasn't initialised.
1407 * Changed data1_read_record and data1_read_node so that the supplied
1408 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1409 doesn't refer to any parts of the "SGML"-buffer.
1411 Fixed bug in server library (Windows version of statserv_remove).
1413 * Changed code so that it compiles as C++. The type definition
1414 of Odr_fun which is a member of Odr_arm was changed. The result is,
1415 that an explicit typecast is needed for the fun pointer when
1416 using Odr_arm - as in:
1417 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1419 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1421 Implemented the new structured date and time definition as approved
1422 by the ZIG. Added schemaId element to the specificTag in Espec-1
1423 (also approved at the last ZIG). Thanks to RVDM.
1425 Added some Object identifiers (RVDM).
1427 Changed the Update Extended Service (RVDM).
1429 Added command "refid" to client which specifies referenceId for
1430 the following requests.
1432 Implemented extended service handling for server. See ztest.c
1433 for an example as well as backend.h. New handlers are registerd
1434 in the Init handler.
1436 * Changed interface for sort in server.
1438 Added new members to statserv_options_block. It allows a server
1439 to read options from another source than just the command line. Thanks
1440 to Charles Woodfield.
1442 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1443 renamed to zboolean. Some C++ compilers complained about the name.
1445 Minor changes to gils.abs. Added index 's' (sort) on title
1446 and date/time-last-modified.
1448 --- 1.4pl2 1998/1/30
1450 Fixed bug in server library regarding inetd mode (-i). This bug
1451 was introduced by release 1.4.
1453 --- 1.4pl1 1998/1/29
1455 Added sort facility in client and backend server interface.
1457 Fixed problem with dependencies in Makefile(s).
1459 Fixed bugs for encoders/decoders of extended services and
1462 Implemented sub-tree feature for schemas. Sub-trees are
1463 referenced in *.abs-files. See explain.abs for an example
1464 of the use of this feature.
1466 Modified bib1.att; local attributes for ANY didn't include
1467 ANY itself (only affects use of the retrieval module).
1469 Fixed bug in plain SGML reader in function data1_read_node:
1470 tags with prefix "var" was incorrectly interpreted as variants.
1472 Added feature "sub-schemas" to enable references to - and definitions
1473 of - group of elements.
1475 * Removed member parent from type data1_element (in data1.h).
1477 Implemented function odr_nullval() that returns the value of
1480 * Removed member num_children from data1_node (in data1.h).
1482 Made NT service interface part of the server library. The
1483 function statserv_main uses the NT service when required and
1484 calls the statserv_start / statserv_close routines.
1486 Routine zget_SearchRequest and zget_PresentRequest fills
1487 resultSetName/Id member with "default" instead of "Default".
1489 Fixed memory leak in server. Request queue member wasn't freed.
1491 Fixed nmem_exit so that memory is freed.
1495 Revised the CCL parser utility to be thread safe.
1497 Added function, oid_ent_to_oid, to replace the function
1498 oid_getoidbyent, which is not thread safe.
1500 * Added nmem_init and nmem_exit to initialize and release
1501 NMEM resources. Function nmem_init should be called once in the
1502 initial thread before NMEM/ODR is used. statserv.c and client.c
1503 have been changed accordingly. The change was necessary to make
1504 NMEM thread safe. The NMEM memory pool is shared amongst threads
1505 in a process. Unix-based applications will still work fine without
1508 Added NT Services interface for the the Z39.50 (statserv) Server.
1509 Refer to the ztest.c source on the usage.
1511 Windows 95/NT port using MSVC5.0. Project files are included in the
1514 * Defined new 'global' handle for the retrieval (data1) system. The
1515 new handled, data1_handle, describes the state of the data1 system.
1516 This handle is passed as first argument to virtually all
1517 data1 related routines. The functions data1_create and data1_destroy
1518 creates and destroys a data1 handle respectively.
1520 Added ODR encode stream member to all backend request structures
1521 init, search, scan etc. This stream should be used to allocate all
1522 memory used for the response when thread safe operation is needed.
1524 Changed the comstack utility, cs_addstr, to be thread safe. The
1525 returned hostname string returned by the function is now part the
1528 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1529 function. The cs_straddr takes a COMSTACK handle as argument, so this
1530 function must be used after cs_create and before bind/connect.
1531 This function is thread safe.
1533 Moved test server to 'ztest' directory - generic server code still
1534 in 'server' directory.
1536 Made prefix query (pquery.c) utility thread safe.
1538 Added new function modifier YAZ_EXPORT to 'export' public DLL
1539 functions when using windows (see include/yconfig.h).
1541 Added definitions to the OID database (util/oid.c) (RVDM).
1543 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1545 Added call to ccl_rpn_delete in client program.
1547 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1548 release of RPN structure.
1550 Added support for C++, headers uses extern "C" for public definitions.
1551 With input from RVDM.
1553 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1554 Thanks to Ronald van der Meer (RVDM).
1556 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1558 Added support for private extensions to the OID database
1559 (oid_setprivateoids()). Thanks to RVDM.
1561 Added optional, physical ANY (key replication)
1563 Fixed null-reference problem in GRS-1 output filter.
1565 Proximity operator added to Prefix Query Format (PQF).
1567 In test client command "base" accepts multiple databases.
1569 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1573 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1575 Smallish bug-fixes in the new encoders/decoders (explain).
1577 Bug fixed in DeleteRequest.
1579 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1581 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1583 Added SOIF syntax (using private OID for now) to retrieval module and client.
1585 Added Update extended service.
1587 Added SearchResult-1 additional info structure.
1589 Added optional CCL (ISO8777) interpreter as separate module. Available
1592 --- 1.2 1996/6/10 (1st anniversary release)
1594 Added Summary record syntax. Lightly tested.
1596 Added OPAC record syntax. Untested.
1598 Added ResourceReport service encoders/decoders. Untested.
1600 Fixed bug in z_Unit - wrong tagging on unitSystem.
1602 Fixed bug in the DiagRecs decoder.
1604 Added options for max PDU size and session timeout to frontend-server.
1606 Added documentation of query-language parsers and other supporting utilities.
1608 [frontend-server] Added Attribute set to the bend_scanrequest API.
1610 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1611 surrogate diagnostics were generated.
1613 [retrieval] Allow multiple local values for attribute.
1615 [retrieval] Allow multiple attributes per element in .abs files. index type.
1617 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1619 --- 1.1pl2 1996/4/10
1621 Minor changes, mostly specific to Zebra's requirements (retrieval)
1625 Repaired bug in frontend server when running multiple listening
1626 endpoints in dynamic mode.
1628 z_External() now won't break if a known, ASN.1 value comes encapsulated
1629 in an octet-string. The value will pass through unmodified in an Odr_oct.
1631 Added a bit of code to the demo client to decode & display
1632 ASN.1-structured records represented in the octet-aligned branch of
1633 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1635 Added z_ext_getentbyref() to the ASN module. Doc updated.
1637 * Completed the SCAN definition in the ASN module. This may break SCAN
1638 code based on older YAZ-versions at compile-time. The fix is easy -
1641 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1642 under the SCAN definition. Remember to initialize this, server-people.
1644 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1645 that this does not extend to ODR and ASN.
1647 Comstack allows insertion of established socket (primarily for
1648 inetd-operation of servers). Doc updated.
1650 Front-end server can now start from the inetd in TCP mode. Doc
1653 --- 1.0pl4 1996/1/24
1657 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1658 the rank and record number.
1660 Adjustments to the frontend server.
1662 Fixed diagnostic BER dumper. It ignored the file argument.
1666 Various changes to retrieval module.
1668 Changed the union discriminators of the protocol files from enums to
1669 ints paired with #defines.
1671 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1674 *Changed operator in the RPN structure to 'roperator', again to avoid a
1677 Fixed problems in Explain decoders/encoders.
1679 --- 1.0pl2 1995/12/6
1681 Memory bug in log module fixed.
1683 --- 1.0pl1 1995/12/5
1685 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1687 Bug in Explain DatabaseInfo module fixed.
1689 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1693 The shift to v1.0 signals that we now consider the *core* functionality
1694 of YAZ reasonably stable (the core being more or less equivalent to
1695 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1696 tested (Explain not at all - though that will happen soonish).
1698 Minor changes to code to support Windows port.
1700 Various minor changes after we're getting to use GRS-1 & co. more.
1702 Added Espec-1 format.
1704 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1705 of the protocol and it cannot be selected when encoding (maps into 'string'
1706 when decoding). Needed to talk to some servers.
1708 Demo client can request simple element set names.
1710 Added Diagnostic Format encoders/decoders.
1712 Added simple Close handling to frontend server (no hooks for resource
1713 reporting yet), and demonstration client.
1715 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1717 --- 1.0b3 1995/08/24
1719 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1720 handled incorrectly when records were requested in the searchResponse. This
1721 will only affect you if you use the frontend-server.
1723 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1724 Test-client will ask for and print GRS1. Ztest will return dummy records
1727 Added Explain encoders/decoders to the service-level API. Untested.
1729 Added Extended Services: Item Order encoders and decoders to the Service-
1730 level API. Untested. We could use a recent copy of the pertinent bits
1731 of the ILL protocol to add those bits.
1733 Added diagnostic format 1 encoders/decoders to the service-level API.
1736 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1737 odr_cons.c, which causes a more correct output.
1739 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1740 was always set to 0 when no records were requested in the searchRequest.
1742 * Added better external-handling. This shouldn't harm old code that
1743 *encodes* externals. It can break code that looks for a
1744 'single-ASN1-type' representation, since those types that are known
1745 are now decoded immediately. Look at the SUTRS sample code in
1746 seshigh.c and client.c. Documentation updated.
1748 Handling of structured records in bend_fetchresponse. Length -1 marks
1749 structured record, type is deduced from format field.
1751 --- 1.0b2 1995/06/27
1752 Fairly quick maintenance release to add SUTRS support.
1754 Fixed handling of SUTRS records in the demonstration client.
1756 * Added format field to the bend_fetchrequest and bend_fetchresponce
1757 structures of the backend API (frontend server). When the record is
1758 returned, the value of the format field is mapped to an OID. The
1759 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1760 of the record. The special value VAL_NONE in the bend_request means
1761 that no specific format was requested by the client. Documentation
1762 updated accordingly. Test server (ztest) will return a fixed dummy
1763 SUTRS record if your client requests SUTRS.
1765 Documentation updated accordingly.
1767 You can now set external libraries and RANLIB support in the top-level
1771 First public release.
