1 Ensured that Present-handler (if defined) is called in GFS before any call to
2 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
3 searchRetrieve requests.
5 Documentation for YAZ is now based on the Docbook XML/XSLT using
6 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
7 is no longer depending on jade/openjade or docbook-to-man scripts.
8 PDF is no longer part of the distribution - but can optionally be
9 made using DSSSL/jadetex or FOP.
11 Added retrieval handling support in Generic Frontend Server to support
12 conversion between MARC/XML as well as XSLTtransforms. See
13 etc/yazgfs.xml for an example.
15 Added Authentication support to Generic Frontend Server in SRU
16 mode. Authentication using HTTP Basic is supported, as is the use
17 of 'x-username' and 'x-password' parameters in the request itself.
19 Added support for a new character set MARC8s identical to MARC8 except
20 that it converts combined characters to single Unicode characters in the
21 Latin-1 range (when possible).
25 ASN.1 compiler 0.4: generates brief Doxygen file header for
26 generated .h/.c files.
28 Utility yaz_iconv now supports conversion to MARC-8.
30 New facilities for the MARC module. The reading - and writing of
31 content are separate methods for the yaz_marc_t handle. The following
32 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
33 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
34 format). Write functions have prefix yaz_marc_write_.. The existing
35 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
36 available. Removed support for OAI-MARC and simplexml (not the
39 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
40 to be returned for this connection.
44 Allow multiple languages and charsets to be specified with
45 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
46 negcharset iso-8859-1,utf-8
48 Translation of proximity nodes from CQL into PQF now works.
50 Moved to automake 1.8, 1.9.
52 Added function yaz_log_set_handler which allows a log handler to be
53 installed. This handler will be called for all log messages. Output
54 to file is also produced; but that can be disabled by passing NULL
55 fname to yaz_log_init_file.
57 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
59 For SRW (including GFS), accept application/soap+xml as content-type
62 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
63 produces NO stylesheet reference even if a default stylesheet is specified
68 Updated Windows package to include yazd.dll + yazd.lib for the
69 Development component.
71 If the environment variable YAZ_LOG is set, then it is used as a
72 string indicating the default level of logging to use if not
73 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
74 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
75 used as before. So, for example, to omit warnings from YAZ logging,
78 cql_transform() now map structure and other attributes before indexes,
79 so that index-specific structures and other attributes can override
80 defaults. So now a combination of mapping specifications such as:
82 index.dc.date = 1=date-modified 4=5
85 cql_transform() now also respects the "always" mapping specification,
86 which establishes an initial set of attributes to be used for all
87 terms except where overridden by more specific attributes associated
88 with the index, relation or modifier.
90 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
91 which mode to use; one of "post", "get" or "soap" (SRW, default).
93 Fixes for yaz_iconv routines: changed trie-based character set conversions
94 to use only non-negative values for bit fields due to Sun's C compiler not
95 supporting negative values.
97 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
98 sequences where not read correctly. Fix by Rustam Usmanov.
100 Updated win/makefile to use options, settings which makes things
101 compile with VS C 2005.
103 --- 2.1.12 2006/02/01
105 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
107 In ZOOM socket code, use select instead of poll on MacOSX.
109 ZOOM-C now support client-side compilation of CQL into RPN that is
110 sent to the server, enabling CQL to be used against all Z39.50
111 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
112 ZOOM_query object, and submit it using ZOOM_connection_search().
113 The CQL-to-RPN translation uses a configuration file, the name of
114 which must be specified in the Connection's "cqlfile" option.
116 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
117 function, which takes as its start-term parameter a ZOOM_query object
118 (which may have had either CQL or RPN set into it).
121 --- 2.1.10 2005/11/29
123 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
124 GFS to support this as well. Backend handler, bend_srw_update, does the
125 update work. Code contributed by Ko van der Sloot.
127 Allow retrieval of Search Result-1 information in ZOOM by the use of
128 options that are attached to a result set. ZOOM documentation updated
131 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
132 UTF-8 conversion. Patch by Raj Patel.
134 Added option -m to GFS to control formatting of timestamps in log file.
136 Added 'exit' as synonym for 'quit' in yaz-client
138 Added support for specifying SRW resultSetId + resultSetIdleTime in a
139 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
140 for the new members. Patch by Ko van der Sloot.
142 Added support for SRU POST. It is supported for content-type
143 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
145 Do not build the separate Multi-threaded (MT) library libyazthread.la.
146 Instead make the library libyaz.la multi-threaded. Threading as a whole
147 can still be disabled by configure option --disable-threads. Previosly,
148 with older GLIBCs there were problems with MT libs under Apache. This
149 has now been fixed a long time ago.
151 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
154 CQL module modified to be case insensitive for relations/indexes/operations.
156 Fixed bug in CQL transform code: incorrect value relationModifieder
159 Added 'show all' command for yaz-client which retrieves all results
162 Added new yaz-client, xmles, which takes a (private) OID and
163 a document to be sent as an extended service request.
165 Describe new yaz-client commands wait_response and set_auto_wait.
167 Increase TCP/IP listener backlog from 3 (which I am guessing was
168 copied from the SunOS manual entry way back when) so SOMAXCONN, so
169 that the socket will queue as many incoming connections as it's able
170 to handle ongoing connections. In other words, it will never now
171 refuse a connection that it would be able to handle merely because
172 it's not got around to accepting() enough of the pending connections
173 yet. This is the behaviour anyway under Linux, where the listen()
174 argument is ignored; but not under BSD and on systems such as
175 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
176 YAZ-based servers should now be uniform across operating systems in
179 yaz-marcdump uses 64-bit file access on some systems. This is enabled
180 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
181 This allows yaz-marcdump to read large MARC batches (>2 GB).
183 Modified all YAZ source files - except the source which is auto-generated
184 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
187 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
188 corresponding to the existing *_setl() function. These allow option
189 values containing arbitrary valuues.
191 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
192 ZOOM_resultset_sort() in new applications. Its behaviour is identical
193 except that it returns an indicator of whether or not the sort
194 criterion was accepted (0 for OK, -1 for invalid).
198 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
199 MARC output rather than returning "new" buffer.
201 yaz-client warns about unknown init options.
203 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
207 Added support for SRW sort in Generic Frontend Server. Patch
208 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
209 sortKeys - or NULL if none is provided.
211 Fixed bug #307: It was impossible to specify indefinite/no timeout
212 for ZOOM_event. Special timeout value -1 now means indefinite timeout
215 Added support for multiple languages and charsets to be specified in
216 ZOOM. Each charset/language is separated by a blank. If negotiation is
217 in effect in init-response, Option
218 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
219 Code based on patch by Vasiliy Osadchuk.
221 Fixed bug #306: infinite recursion that occurred when calling
222 yaz_log_level_init as the first call (before other log level or
225 Fixed bug in scan handling in front end server: if preferred-Position-In-
226 Response was non-present, a NULL pointer referece was performed.
230 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
231 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
232 now defined for all those error codes. So instead of putting 109 in
233 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
234 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
236 Modified the yaz-marcdump utility to skip garbage bytes between MARC
239 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
241 Program yaz-client now exits and produces an error message if multiple
242 Z39.50 servers are specified on the command line (none or one allowed
245 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
250 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
252 Fixed bug #272: Preserve spacing for CCL terms.
256 Added support for virtual hosts and multiple backend servers for
257 the YAZ frontend server. The configution is XML based and
258 support specificition of CQL to RPN mappings and explain information.
259 See section "Virtual Hosts" in the YAZ manual.
261 Extended OPAC display utility. OPAC display utility renders
262 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
263 to supplement yaz_marc_decode_wrbuf.
265 Fixed a bug in MARC decoder that could caused it to crash for some
266 invalid MARC records. More diagnostics and warnings where added in
267 XML output (warnings, etc are stored in comments).
269 --- 2.0.34 2005/02/08
271 Fixes for UNIX domain sockets. Bug #261.
273 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
275 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
276 Added yaz_marc_subfield_str which defines subfield lead string which is
277 used in YAZ_MARC_LINE format. Default string is blank+$. Added
278 yaz_marc_endline_str which defines end of fields string used in
279 YAZ_MARC_LINE format. Default string is newline.
281 Experimental support for MarcXChange. This format can be produced
282 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
283 http://www.bs.dk/standards/MarcXchange.xsd
285 Added yaz-client commands scansize that sets maximum number of
286 entries to be returned by scan.
288 --- 2.0.32 2005/01/11
290 Added support for SRW scan in yaz-client and Generic Frontend Server.
292 * Added whereInList member to SRW Scan Term.
294 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
296 Fixed NMEM system to return aligned blocks on the smallest boundaries
297 that are suitably aligned for all possible types on the particular
298 architecture YAZ is being built for.
300 --- 2.0.30 2005/01/04
302 Fixed numerious warnings that was issued with newer versions of GCC.
304 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
305 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
308 Make YAZ Generic Frontend Server slightly faster.
310 Enhance (and reduce) logging for Generic Frontend Server.
312 Revert YAZ log system so that it flushes every write operation
313 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
315 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
316 instead of LOG_, due to name clash with syslog(3). LOG_ are still
317 present. New applications should define YAZ_USE_NEW_LOG=1 - this
318 will effectively disable old definitions.
320 --- 2.0.28 2004/11/09
322 Added yaz_log_time_format which specifies log format using
325 Added yaz_log_module_level which returns mask for a module. Value
326 is non-zero mask a if module is enabled; zero if disabled.
328 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
329 in include/yaz/cql.h.
331 Fixed bug #176: Dont throw diagnostics on empty SRU args.
333 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
335 Fixed bug #172: RPM builds does not enable SSL.
337 Doxyfile.in part of dist. Doxyfile generated by configure.
339 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
340 are given and the corresponding component does not exist.
342 Extend CCL documentation in YAZ reference. Describe r=r.
344 --- 2.0.26 2004/10/01
346 Fixed MARC->MARCXML conversion to properly deal with
347 fields, subfields, indicators having non-ASCII characters.
349 Fixed MARC->MARCXML conversion so that ASCII control characters
350 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
353 Added YAZ GFS support for conversion from Z39.50 surrogate
354 diagnostics to SRW surrogate diagnostics.
356 Bug fix: YAZ GFS did not return schema in explainResponse.
358 --- 2.0.25 2004/09/30
360 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
361 now converts recordSchema to elementSetName as well as schema URI.
363 Fixed bug in COMSTACK that prevented HTTP request packages from being
366 --- 2.0.24 2004/09/29
368 Added CCL facility r=r "range" which is similar to r=o "ordered" but
369 does not require white-space before and after the dash in a range, e.g.
370 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
373 Fixed a few AC_TRY_LINK configure tests that did not operate properly
374 due to new GCC removing "redundant" code.
376 Added yaz-client commands scanpos and scanstep that sets preferred
377 position and step-size for scan.
379 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
381 Added CCL utility ccl_qual_buf which parses one or more CCL
382 spec lines in a buffer.
384 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
385 of name and value - ignoring empty lines and comments.
387 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
389 Added odr_get_element_path which returns current element path for an
390 ODR handle. This utility is useful in error handling or user-defined
393 Added ODR_PRINT utility odr_set_stream which is is a more generic
394 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
395 to a write function and pointer to close function. The close function - if
396 non-NULL - will be called during odr_destroy.
398 Fixed bug in CCL parser where truncation char was not removed from
399 right side when truncation=both was in effect.
401 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
404 --- 2.0.23 2004/08/11
406 Fix buffer overrun in CQL parser when dealing with proximity (%).
408 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
409 to UTF-8/UCS conversion is now only based on codetables.xml.
411 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
413 --- 2.0.22 2004/08/06
415 Add support for more "commit changes" in ZOOM (uses Extended Services).
417 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
420 Yet another small fix for configure of SSL.
422 --- 2.0.21 2004/05/14
424 Fix SSL libs for configure when --with-openssl=DIR is given.
426 --- 2.0.20 2004/05/10
428 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
430 SSL comstack now uses yaz.pem certificate file on server side
431 by default. Certificate filename can be configured by calling
432 comstack function cs_set_ssl_certificate_file before cs_bind is used.
434 Fix bug regarding multiple calls to ZOOM_connection_connect.
436 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
438 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
439 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
441 ZOOM now allows inspection of X509 peer certificate for verification.
442 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
444 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
445 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
446 as "modular" but it simplifies things.
448 Added cs_get_peer_certificate to that returns peer X509 PEM.
450 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
451 NULL if SSL is unavailable.
453 Documentation about MARC decoding tools.
455 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
457 --- 2.0.19 2004/03/30
459 Rename CHANGELOG to NEWS to follow GNU style packing.
461 Fix bug with missing initialization of member in init_diagnostics.
462 This bug affects threaded version of GFS server.
464 --- 2.0.18 2004/03/20
466 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
469 Ensure zlib.dll is packed with Windows install.
471 --- 2.0.17 2004/03/17
473 Fix encoding of xsd:string to use text instead of CDATA.
475 Fix endless loop in CQL parser with unbalanced ".
477 Use a more compact way to store MARC-8 conversion tables.
479 --- 2.0.16 2004/03/16 Debian only
481 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
484 Update CQL parser to use new CQL 1.1 modifiers for booleans and
489 --- 2.0.15 2004/03/01
491 Another fix for decoding of XML packed records.
493 --- 2.0.14 2004/02/25
495 Fixes for Chunked encoding. White space not ignored after length spec.
497 Update NS and use default NS for SRW diagnostic elements.
499 --- 2.0.13 2004/02/23
501 Implement ZOOM_resultset_cache_reset which resets record cache.
503 Implement ZOOM_resultset_sort which sorts a result set.
505 Implement chunked HTTP transfer.
507 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
509 --- 2.0.12 2004/02/16
511 Added member 'schema' to bend_explain_rr structure so that backend
512 can specify explain record identifier. Defaults to Zeerex 2.0.
514 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
516 --- 2.0.11 2004/02/16
518 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
521 Added init command for yaz-client which sends "extra" init request.
523 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
524 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
526 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
528 Make ZOOM error code for "invalid query".
530 Fixed compilation for SSL which wasn't properly enabled for all platforms.
532 --- 2.0.10 2004/02/05
534 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
537 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
539 Added option -p <file> to make Generic Frontend Server to write PID file.
541 Added option -D to put Generic Frontend Server in background on its own.
543 Make ZOOM C recognize option "password". If unset, "pass" is used
544 (for backwards compatibility).
546 Fixed a bug in Generic Frontend Server that could make it crash if a
547 client sets characterSetNegotation bit, but didn't pass negotiation stuff
550 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
551 Must be issued before open, in order to be in effect.
553 --- 2.0.9-6 2004/01/12 Debian/Windows
555 Make the SRU server more picky WRT unknown params, etc.
557 Bug fix: ZOOM scan response didn't return displayTerm - when present.
559 New YAZ client command, options, that sets Z39.50 options.
561 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
562 options from a string of tokens (one token for each option bit).
564 Update SRW diagnostic code messages.
566 --- 2.0.9-5 2004/01/07 Debian/Windows
568 Handle user defined stylesheet for SRW/SRU.
570 --- 2.0.9-4 2004/01/06 Debian/Windows
572 Fix bug in decoding of Content-Length.
574 --- 2.0.9-3 2004/01/06 Debian/Windows
576 Fix a bug with decoding of XML packed records.
578 --- 2.0.9-2 2004/01/05 Debian only
580 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
582 Fix bug in SRW/SRU diagnostics decoding.
586 Fixed bug in Generic Frontend Server which could drop records exceeding
587 preferred message size. Reported and fixed by Irina Dijour.
589 Fixed calculation of package size for structured records in Generic
590 Frontend Server. Reported and fixed by Irina Dijour.
592 Fixed namespace for SRW/SRU diagnostics.
594 Fixed SEGV in yaz-client that occured for HTTP connection errors.
598 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
599 this version is incompatible with version 1.0 and older YAZ SRW/SRU
602 CQL changes to reflect recent changes to the specification:
603 * Documentation talks about context sets instead of index sets.
604 * Documentation talks about indexes instead of qualifiers.
605 * The CQL-to-PQF transformer's configuration file now uses
606 "index.set.name = <attributes>" instead of the old form
607 "qualifier.set.name = <attributes>". (Both forms are still
608 understood but the latter is deprecated.)
609 * CQL terms with no explicit index specified are now interpreted as
610 cql.serverChoice instead of srw.serverChoice (which of course
611 behaves exactly the same.)
615 MARC conversion can now generate ISO2709 output in another
616 character set. yaz-marcdump uses this facility if you invoke it
619 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
620 functions from there can be used from C++.
624 Frontend server now transfers memory from decoded packages to stream
627 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
628 references to show up.
630 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
631 the ZOOM Abstract API. The older names for the same options are still
632 also supported for the benefit of old applications.
634 ZOOM-C supports "implementationId" and "implementationVersion" options
635 to go along with "implementationName". These allow the user code to
636 specify identification strings to be sent to servers.
637 Add OID for the new ExtLite attribute set.
639 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
640 as requested/supplid by Ere Maijala <ere@atp.fi>
642 For generic frontend server, reverse the order of
643 "toolkit-supplied / application-supplied" strings sent as implementationId,
644 Name and Version. Also, remove the spaces around the slash. This brings
645 the GFS in line with the behaviour of ZOOM-C on the client side.
647 Add function ZOOM_scanset_display_term.
649 yaz-client shows scan displayTerm if present.
651 Utility yaz-iconv is now installed by default along with the man page
654 Extend configure check for OpenSSL to use pkg-config where available (such
657 Incorporate patch by Morten Bogeskov which allows a Unix file socket
658 server to specify uid/gid/mask for socket using the format
659 unix:[user=uid,][group=gid,][umask=mask,]file=path
660 If file= is omitted the existing format is assumed, e.g.
662 in which case the mask is 0666 (rw for everybody).
664 Major restructure of YAZ source. All source in libyaz is in src directory.
665 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
666 util (utility programs such as ASN.1 compiler, yaz-marcdump).
668 Added man page for utility yaz-marcdump (used to be called marcdump).
669 yaz-marcdump is installed by 'make install'.
671 Fixed a memory leak in Generic Frontend Server that occurred when decoding
672 of incoming package failed.
674 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
676 Change prototype of odr_perror: add const to message string.
678 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
680 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
681 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
682 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
683 DNS lookup. There should not be any compatibility problems with this
684 assuming that blocking=1 or 0 is used.
686 Fix bad reference in UNIX comstack in function cs_addrstr.
688 Fix for compilation on AIX.
690 The generic front-end server (server/seshigh.c) now supports returning
691 Init diagnostics to the client in User-information-field, in
692 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
697 Allow any CQL relation (not just all,any,exact,scr).
699 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
700 that features the same UI.
702 Implemented command update0 in YAZ client which is equivalent to
703 update but uses old of Ext Update ASN.1.
705 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
706 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
707 Previously no OID was used for this info.
709 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
710 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
711 returns 'malformed search term' otherwise.
713 SortResponse member resultCount now set to NULL in sort handler of
716 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
719 Add three new utility functions for translating OIDs between various
720 formats -- symbolic name such as "Usmarc", minus-1-terminated int
721 arrays and dotted strings such as "1.2.840.10003.9.5.1":
722 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
723 char *oid_to_dotstring(const int *oid, char *oidbuf);
724 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
726 Reverted modifications for ES Update definition for z_IU0Update
727 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
728 is back to YAZ 2.0.2.
730 String value attributes for CCL parser.
732 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
733 which their FirstSearch server returns in Init responses, sometimes
734 carrying useful diagnostic information when Init fails. This has the
735 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
736 "z39.50/oclcui.asn", where its definition is somewhat different from
737 what OCLC document on their web-site, as required to interoperate with
740 Support for anonymous authentication in yaz-client. Use the command
743 * Fix the OID of the Index Data-local "admin" Extended Service from
744 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
745 the 1000, which indicates a locally-defined OID, was a mistake.
749 Fix CCL directive @case handling so that it affects string match for
750 both CCL keywords and qualifiers.
752 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
753 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
754 Decoder has been updated with ASN.1 changes as listed in
755 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
756 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
757 z_IUUpdate, remains unchanged.
759 ZOOM_record_get may now return a record in a specific character set.
760 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
761 "from" is the character set of record as returned by target. "to" is
762 the character set to be returned. If omitted, "to" is UTF-8.
764 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
766 New ODR utility, odr_getelement, which returns name of element for
767 which encoding/decoding failed.
769 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
770 in cases where a required element was omitted.
772 Bug fix: some MARC8 sequences were not converted.
774 New ZOOM option "step" which specifies number of records to be
775 retrieved in one chunk. Used in conjunction with "start" and "count".
777 SRW support for yaz-client. Use scheme http: to use it, e.g.
780 yaz-client no longer does (un)intelligent character set conversions
781 by default. Can be enabled with charset and marc_charset commands.
783 xmalloc trace fix for 64-bit systems such as DEC alpha.
785 Solaris 2.6 compile fix.
787 New function, cql_strerror() translates SRW error codes, as returned
788 by cql_transform_error(), into human-readable English strings. Used
789 in yaz-client diagnostics when appropriate.
791 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
792 converts it into a type-1 query which is sent to the server. This
793 makes CQL available for use with all Z-servers, as opposed to the tiny
794 minority that can handle CQL queries themselves.
798 New Debian package layout similar to the Redhat Package layout.
800 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
801 and search result respectively.
805 Redhat package is now several packages: libyaz (runtime libraries),
806 libyaz-devel (development and documentation, and yaz (utility programs).
807 Package spec file by Morten Bøgeskov.
809 New member 'schema' in struct bend_fetch_rr which the name of requested
810 schema (SRW/SRU) for record (or NULL if none was given). The fetch
811 handler MAY set this to reflect the schema of the returned record.
813 New member 'display_term' in struct scan_entry. GFS now sets member entries
814 and allocates scan entries to be filled by user scan handler. In previous
815 version, entries member was allocated by the scan handler. That still works,
816 but the GFS will ignore member display_term - assuming it was NOT set by
817 the handler. The fact that the GFS now allocates the entries both allows
818 for new members and makes a scan handler easier to write.
820 Fix CQL lex buffer overflow.
822 SRW/SRU recordPacking. For SRW default recordPacking is string. For
823 SRU default recordPacking is string.
825 SRU protocol support for frontend server.
827 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
829 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
831 Added scan for the ZOOM shell (zoomsh).
835 * String Identifers for Schemas (Amendment 5).
836 http://lcweb.loc.gov/z3950/agency/amend/am5.html
837 Old definition for schema
838 Odr_oid *schema; /* OPT */
843 Z_InternationalString *uri;
844 #define Z_Schema_oid 1
845 #define Z_Schema_uri 2
848 * resultCount parameter to Sort Response (Amendment 1).
849 http://lcweb.loc.gov/z3950/agency/amend/am1.html
851 Support for SRW 1.0 over HTTP. This is an optional feature and
852 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
855 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
856 on the same port. SRW SearchRetrieveRequests are mapped
857 to bend_init,bend_search,bend_fetch,bend_close.
859 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
861 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
862 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
864 ZOOM connections are SRW based if schem http is used for hostname
865 in connect, e.g. z = ZOOM_connection_new("http://myserver");
866 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
868 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
869 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
870 distance=n, order=true/false, relation=le, prox unit=word. If
871 n is omitted, distance 1 is used.
873 Fixed problem with C compiler include path in wrong order.
875 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
876 on Solaris. Patch from Ko van der Sloot.
878 New MARC decode API. All new functions operate on a yaz_marc_t
879 handle. The most important new functions are: yaz_marc_create,
880 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
881 decode and destroy respectively. Decoder can produce formats
882 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
883 include/yaz/marcdisp.h.
885 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
886 to UTF-8, UCS-32, wchar_t or Latin-1.
888 * Prototypes for yaz_iconv_-functions moved to separate header
889 include/yaz/yaz-iconv.h.
891 Make a few private functions 'static' in unix.c. This prevents
892 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
894 For ZOOM connection, the options targetImplementation{Id,Name,Version}
895 are set when Init Response is received.
897 New function ZOOM_connection_error_x similar to ZOOM_connection_error
898 but returns diagnostic set as well.
900 New function yaz_strerror which is a portable wrapper for
901 strerror/strerror_r/GetLastMessage.
903 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
904 is returned for MARC. If type is "oai", then OAI MARC is returned.
906 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
911 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
913 Fix bad race conditions on SIGTERM and terminate gracefully in
916 Move retrieval (data1) module to Zebra since nobody seems to be
919 Add GRS-1 render for ZOOM using same format as yaz-client.
923 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
925 Fix broken ESpec handling in data1 module.
927 SGML reader parses comments and makes them part of the data1 tree.
929 Added several type casts so that YAZ compiles as C++ code.
931 ZOOM didn't handle PDU encoding failures properly.
933 Added more Bib-1 diagnostics (approved extensions).
935 GNU configure: better check for iconv.
937 More portable use of accept, getpeername. Check for socklen_t. Use
938 int/size_t if socklen_t is not defined.
942 PQF parser rejects bad queries - including those with extra
943 characters in them. PQF parser used to silently ignore that.
944 Cleaner API for PQF added, which allows you to get detailed
945 error information for bad queries (see yaz/pquery.h).
947 Fixed bug in ZOOM_record_get for type "database".
949 Implemented mini iconv library supporting conversions between
950 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
952 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
956 Fixed ZOOM C record cache so that preferredRecordSyntax and
957 elementSetName is used to check for already fetched records.
961 Added three members in bend_initrequest structure to facilitate
962 character set negotiation.
964 Fixed a bug in frontend server that could cause indefinite
965 loops under rare conditions.
967 Revised character set utilities (charneg.h) so that encoding
968 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
970 For PQF, directive @term <type> sets term type for Scan/Search.
971 Here <type> is general, string, numeric, null. The term type
972 is inherited - just like @attr.
974 New call odr_set_charset that sets character set conversion for
975 international-strings on a ODR stream. Prototype is:
976 int odr_set_charset(ODR o, const char *to, const char *from);
977 The InternationalString is still represented as C string in YAZ
978 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
979 won't). On the protocol level, you can use any encoding.
981 Support for UNIX sockets in ZOOM.
983 Solaris recv sometimes returns errno == ENOENT. It is treated as
984 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
986 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
987 both client and server. Code by Morten Bøgeskov.
991 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
992 that they can be used directly from Visual Basic. You must recompile
993 your windows APP if you're using ZOOM.
995 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
996 Commands "lang" and "charset" sets language and character set respectively.
997 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
998 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1000 Attributes from multiple CCL fields may be OR'ed rather than merged
1001 using directive "@field or". Fields are still merged by default -
1002 equivalent to "@field merge".
1004 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1007 Fixed bug in zget for parameter ExtendedServicesResponse.
1011 --- 1.8.6 2002/03/25
1013 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1015 Client displays USR.1:SearchResult-1 (hits per term).
1017 Additional Search Info for search in Generic Frontend Server.
1019 Fixed CCL parsing of "field=s".
1021 WIN32 installer - using the excellent NSIS software from nullsoft.
1023 Fixed CCL parsing of "field = - <number>".
1025 Added function yaz_marc_decode that decodes MARC for line mode
1026 display or XML (similar to that used by JZKit).
1028 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1029 Z39.50. But ISO/ILL was, however.
1031 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1032 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1034 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1035 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1037 --- 1.8.5 2002/02/03
1039 New YAZ client features: Command completion and new commands:
1040 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1041 Code provided by Jacob Poulsen.
1043 New call oid_trav, that visits all registered OIDs via callback.
1045 Function ZOOM_record_get now returns const char pointer rather than
1046 void pointer. It saves a lot of type casts.
1048 For YAZ client, command "auth" now allows you to set authentication
1049 in IdPass style. It is enabled when three tokens are given - order
1050 is user, group and password.
1052 Fix memory leaks in MARC record handling for ZOOM.
1054 New option for YAZ client, -k <kilobytes> that sets
1055 maximum record size. Similar to -k option for generic frontend
1056 server and yaz-ztest.
1058 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1060 Prefix query parser reports "fail" when bad attribute set is given.
1062 Fix in MARC decoder. Proximity logging. Fix for attribute set
1063 in scan handler for server. Patches by Shigeru Ishida.
1065 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1068 Configure option --with-openssl=<dir> now works when a directory is
1069 specified. Patch provided by Morten Bøgeskov.
1071 New option for YAZ client, -u <auth>, that sets authentication.
1073 ZOOM fix: error information was sometimes "missing", since error
1074 was cleared/reset too when it shouldn't.
1076 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1078 --- 1.8.4 2002/01/04
1080 Scan for ZOOM API. New object ZOOM_scanset. New functions
1081 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1082 ZOOM_scanset_destroy.
1084 New ZOOM function, ZOOM_connection_last_event, that returns type
1085 of last event (such as "receive data", "send data", "apdu received",
1088 New ZOOM option, schema, that specifies schema for retrieval.
1090 New CCL feature. Qualifiers can be aliases for one or more
1091 other qualifiers (if more than one is given, OR is used).
1093 ZOOM uses named result sets if target supports it.
1095 Two new YAZ client commands: . (dot, which sources a script of YAZ
1096 client commands), and ! (to execute shell command.). Implemented
1099 Working on Debian packages.
1101 --- 1.8.3 2001/11/19
1103 YAZ client enables named result sets only if target supports it.
1105 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1107 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1108 with key="host" to get same result.
1110 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1111 Function Z3950_resultset_record(s) returns references to records
1112 "owned" by resultset. To become owner use Z3950_record_clone.
1114 Function z_ext_record handles Extended Services. Thanks to
1117 --- 1.8.2 2001/11/12
1119 CCL Parser fix: ignore token comma when dealing with and-lists.
1121 Documentation updates for COMSTACK.
1123 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1124 Changed prototype Z3950_records. For some functions, int parameters
1125 were changed to size_t.
1127 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1130 New MARC decode/display function, marc_display_exl, which properly rejects
1131 non-ISO2709 records. YAZ client uses it.
1133 --- 1.8.1 2001/10/29
1135 Fix bug: local attribute set wasn't set correctly in PQF strings.
1139 * Old Z39.50 codecs no longer supported.
1141 Added ZOOM C binding. See http://zoom.z3950.org/
1143 Renamed states for COMSTACKs to avoid confusion with events.
1145 Implemented cs_look and proper cs_rcvconnect.
1147 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1149 Configure detects POSIX threads on OpenBSD.
1151 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1152 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1154 When error is returned from present handler, non-surrogate diagnostic
1155 is returned in present response (and fetch handler is no longer called).
1157 * Minor adjustments to pquery parser (PQF). Token characters may be
1158 escaped by using backslash (C-style).
1160 PQF parser allows string attribute values to be specified. For @attr,
1161 non-numeric characters after the equal-sign are treated as strings
1162 (e.g. @attr 9=title).
1164 CCL trunction character may be defined (@truncation in file)
1166 * function zget_ExtendedServicesRequest sets waitAction to
1167 waitIfPossible (was wait).
1169 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1172 CCL operator names may be set in field definition files (CCL_bibset).
1173 See ccl/bib1 for an example.
1175 Fixes in ASN.1 compiler for C++ compatibility.
1177 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1178 and "op_or" to avoid conflict with C++.
1180 Fixed problem with GNU readline detection on Redhat 7.0.
1182 Added step-size for Scan backend handler.
1184 Fixed bug that made the frontend server crash when no attribute
1185 set was specified for scan.
1187 Front-end server automatically switches to original working directory
1188 when installed as an NT service. Previously -w had to be specified to
1191 Added extended attributes for retrieval module (data1), so that data1
1192 records carry d1_readXML/SGML attributes. d1_read also supports
1193 null-data rules ( <tag/>)
1195 On UNIX when POSIX threads are available, a separate library libyazthread
1196 is created. Programmers should link with that library and the yaz library
1197 when using threads. The reason for the split was that some applications
1198 on Linux, such as Apache, doesn't work well when using shared objects that
1201 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1202 (or any frontend server) in SSL mode by specifying ssl: followed by
1203 address. Only tested on UNIX.
1205 Added feature for CCL module. Virtual structure s=al or s=ol generates
1206 and-list and or-list respectively instead of phrase search.
1210 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1211 log_mask_str. This was done to avoid name conflicts with other libraries
1212 (such as other PHP extensions).
1214 Added raw OID member for preferred record syntax (request_format_raw)
1215 and returned record syntax (output_format_raw) for backend fetch method.
1217 Config file yaz-config now accepts options so that it returns specific
1218 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1220 Shared library support for UNIX using GNU libtool.
1222 * Modified backend interface. Request/Response struct's replaced by
1223 one read/write C struct. For example bend_fetchrequest and
1224 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1225 Every handler - even search has to be registered in bend_init
1226 handler. This means that the YAZ library no longer refers to
1227 external functions and it makes it possible to make the whole
1228 thing a single DLL/SO.
1230 Added Segment handler for backend server.
1232 Added Zmbol/Zebra administrative functions to YAZ client.
1234 Threaded frontend server on UNIX (when POSIX Threads are available).
1235 Starting the server with option -T enables multi-threading.
1239 Added configure option --enable-comp/disable-comp to control use
1240 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1241 located in sub directory asn.
1243 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1244 in ${exec_prefix}/bin along with the other programs yaz-client and
1247 GNU automake used to maintain makefiles.
1249 Added several OID's.
1251 Changed retrieval module so that we can load records with no abstract
1252 syntax defined. Tagpaths in these records are fully composed of string
1255 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1259 On UNIX, the generated makefile now supports a proper 'make install'.
1260 The prefix can be set via GNU configure to set the install location
1261 (default is /usr/local).
1263 * YAZ programs client and ztest were renamed to yaz-client and
1264 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1265 locations, such as /usr/bin,/usr/local/bin,etc.
1267 * YAZ Header files were moved from include to include/yaz. YAZ Header
1268 files are referred to as include <yaz/log.h> rather than <log.h>.
1269 The YAZ include path (-I ..) is therefore the same as before. Programmers
1270 should update their #include statements or use -Ipath/include/yaz
1271 instead. The main motivation for doing this change is that YAZ header files
1272 can be installed in "standard" locations /usr/include,/usr/local/include
1273 without introducing conflicts, since ALL YAZ header files are stored
1274 in subdirectory yaz (under /usr/include for example).
1276 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1277 rather than project/workspace files. We switched because project files
1278 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1281 Changed name of logging function, logf, to yaz_log, to prevent name
1282 clash with some math-log functions. The YAZ header log.h defines logf
1283 to yaz_log (#define) so there should be no incompatibilities by this
1286 Added bend_start/bend_stop handlers for server. These handler are
1287 called on start/stop of server. For windows they are called whenever
1288 a service is started/stopped.
1290 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1291 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1292 in util/yc.tcl. The auto-generated C code structures are, in a few
1293 cases, incompatible with the old decoders. There are differences in the
1294 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1295 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1296 The preprocessor variable ASN_COMPILED is defined when the compiled
1297 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1298 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1299 wish to use the old encoders/decoders you can specify --disable-yc
1302 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1303 version so that it supports both new - and old version of DB Update
1305 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1306 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1307 change. The name parameter can be set to 0 in which no name is specified
1308 for the construction. The macros odr_implicit and odr_explicit sets name
1309 parameter to zero for the construction involved. New macros
1310 odr_implicit_tag and odr_explicit_tag are similar to the others,
1311 except that a name parameter is added. For programmers' that don't use
1312 ODR they probably only need to change the call to z_APDU and z_External.
1314 Added access control facility by interfacing the TCP wrapper library.
1315 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1316 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1317 name of the daemon and enables the access control as specified in
1318 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1320 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1321 den Dool <H.M.vdnDool@kub.nl>.
1323 Added reference ID parameter to most functions in server API - refer
1324 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1326 Changed name of ccl library to libccl.a (was ccl.a).
1328 Fixed bug in decoder for Explain (Category TargetInfo).
1330 Added support for GNU readline in client. Thanks to Jacob Poulsen
1331 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1333 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1334 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1335 IMPLEMENTATION! This change was made to the development version before
1336 the ZIG decided to retract the amendment. If any users MUST be
1337 compatible with the original Update definition, PLEASE CONTACT US, and
1338 we will include a separate definition corresponding to the old Update
1339 ES. Note that because of the change to the ASN.1 of the
1340 TaskPackageRecordStructure we cannot define a single structure that
1341 will support both versions.
1343 * Added const modifier to buffer parameter for some ODR/BER encoding
1344 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1345 completeWAIS, odr_dumpBER.
1347 Fixed bug in client.c which caused a crash when a scanResponse didn't
1348 contain positionOfTerm.
1350 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1351 * will cause an error in a client if a non-YAZ target sends both a
1352 * list of Scan entries and non-surrogate diagnostics.
1354 Retrieval module enhancements. Tag sets may be typed in the reference
1355 to it. From the .abs-file the "tagset" directive takes a third optional
1356 integer type for the tag set referenced. From a .tag-file the "include"
1357 directive takes a third optional type as well. The old "type" directive
1358 in the tag set itself is still recognized but acts as the default type
1361 Backend interface change. Individual Scan terms returned from bend_scan
1362 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1363 in include/backend.h.
1365 Retrieval module enhancements. Multiple tag sets and attribute sets may
1366 be specified in abstract syntax specs. Revised the error/warning for
1367 logging messages reported by the retrieval module when reading the
1370 Object Identifier system (oid_..) changed. The API is backwards
1371 compatible but the oid-routines now allocates new OID's when needed.
1372 Raw OID's may be specified in oid_getvalbyname.
1374 YAZ now uses GNU configure to generate Makefile(s).
1376 * Minor changes in some of the member names of DeleteResultSetRequest and
1377 DeleteResultSetResponse. See include/proto.h.
1379 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1380 and added member 'languages' in TargetInfo (which was missing).
1382 Changed the way attribute sets are handled in the retrieval
1383 module. These are now cached, just like the abstract syntaxes
1386 Changed YAZ so that it links with compiled ASN.1.
1388 Added Explain-schema definitions and mapping routines. The following
1389 Explain categories have been implemented: AttributeDetails,
1390 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1392 Fixed minor bug in Windows version of Server Library.
1394 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1396 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1398 Added EXTERNAL: UNIverse Resource Report (non-standard).
1400 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1401 ENUMERATED and SET OF.
1403 * Added 'const' to some of the char pointer arguments for the
1404 functions, data1_read_node, data1_getelementbytagname,
1405 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1408 Fixed bug in data1_insert_taggeddata - the last_child member of
1409 parent wasn't initialised.
1411 * Changed data1_read_record and data1_read_node so that the supplied
1412 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1413 doesn't refer to any parts of the "SGML"-buffer.
1415 Fixed bug in server library (Windows version of statserv_remove).
1417 * Changed code so that it compiles as C++. The type definition
1418 of Odr_fun which is a member of Odr_arm was changed. The result is,
1419 that an explicit typecast is needed for the fun pointer when
1420 using Odr_arm - as in:
1421 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1423 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1425 Implemented the new structured date and time definition as approved
1426 by the ZIG. Added schemaId element to the specificTag in Espec-1
1427 (also approved at the last ZIG). Thanks to RVDM.
1429 Added some Object identifiers (RVDM).
1431 Changed the Update Extended Service (RVDM).
1433 Added command "refid" to client which specifies referenceId for
1434 the following requests.
1436 Implemented extended service handling for server. See ztest.c
1437 for an example as well as backend.h. New handlers are registerd
1438 in the Init handler.
1440 * Changed interface for sort in server.
1442 Added new members to statserv_options_block. It allows a server
1443 to read options from another source than just the command line. Thanks
1444 to Charles Woodfield.
1446 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1447 renamed to zboolean. Some C++ compilers complained about the name.
1449 Minor changes to gils.abs. Added index 's' (sort) on title
1450 and date/time-last-modified.
1452 --- 1.4pl2 1998/1/30
1454 Fixed bug in server library regarding inetd mode (-i). This bug
1455 was introduced by release 1.4.
1457 --- 1.4pl1 1998/1/29
1459 Added sort facility in client and backend server interface.
1461 Fixed problem with dependencies in Makefile(s).
1463 Fixed bugs for encoders/decoders of extended services and
1466 Implemented sub-tree feature for schemas. Sub-trees are
1467 referenced in *.abs-files. See explain.abs for an example
1468 of the use of this feature.
1470 Modified bib1.att; local attributes for ANY didn't include
1471 ANY itself (only affects use of the retrieval module).
1473 Fixed bug in plain SGML reader in function data1_read_node:
1474 tags with prefix "var" was incorrectly interpreted as variants.
1476 Added feature "sub-schemas" to enable references to - and definitions
1477 of - group of elements.
1479 * Removed member parent from type data1_element (in data1.h).
1481 Implemented function odr_nullval() that returns the value of
1484 * Removed member num_children from data1_node (in data1.h).
1486 Made NT service interface part of the server library. The
1487 function statserv_main uses the NT service when required and
1488 calls the statserv_start / statserv_close routines.
1490 Routine zget_SearchRequest and zget_PresentRequest fills
1491 resultSetName/Id member with "default" instead of "Default".
1493 Fixed memory leak in server. Request queue member wasn't freed.
1495 Fixed nmem_exit so that memory is freed.
1499 Revised the CCL parser utility to be thread safe.
1501 Added function, oid_ent_to_oid, to replace the function
1502 oid_getoidbyent, which is not thread safe.
1504 * Added nmem_init and nmem_exit to initialize and release
1505 NMEM resources. Function nmem_init should be called once in the
1506 initial thread before NMEM/ODR is used. statserv.c and client.c
1507 have been changed accordingly. The change was necessary to make
1508 NMEM thread safe. The NMEM memory pool is shared amongst threads
1509 in a process. Unix-based applications will still work fine without
1512 Added NT Services interface for the the Z39.50 (statserv) Server.
1513 Refer to the ztest.c source on the usage.
1515 Windows 95/NT port using MSVC5.0. Project files are included in the
1518 * Defined new 'global' handle for the retrieval (data1) system. The
1519 new handled, data1_handle, describes the state of the data1 system.
1520 This handle is passed as first argument to virtually all
1521 data1 related routines. The functions data1_create and data1_destroy
1522 creates and destroys a data1 handle respectively.
1524 Added ODR encode stream member to all backend request structures
1525 init, search, scan etc. This stream should be used to allocate all
1526 memory used for the response when thread safe operation is needed.
1528 Changed the comstack utility, cs_addstr, to be thread safe. The
1529 returned hostname string returned by the function is now part the
1532 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1533 function. The cs_straddr takes a COMSTACK handle as argument, so this
1534 function must be used after cs_create and before bind/connect.
1535 This function is thread safe.
1537 Moved test server to 'ztest' directory - generic server code still
1538 in 'server' directory.
1540 Made prefix query (pquery.c) utility thread safe.
1542 Added new function modifier YAZ_EXPORT to 'export' public DLL
1543 functions when using windows (see include/yconfig.h).
1545 Added definitions to the OID database (util/oid.c) (RVDM).
1547 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1549 Added call to ccl_rpn_delete in client program.
1551 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1552 release of RPN structure.
1554 Added support for C++, headers uses extern "C" for public definitions.
1555 With input from RVDM.
1557 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1558 Thanks to Ronald van der Meer (RVDM).
1560 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1562 Added support for private extensions to the OID database
1563 (oid_setprivateoids()). Thanks to RVDM.
1565 Added optional, physical ANY (key replication)
1567 Fixed null-reference problem in GRS-1 output filter.
1569 Proximity operator added to Prefix Query Format (PQF).
1571 In test client command "base" accepts multiple databases.
1573 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1577 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1579 Smallish bug-fixes in the new encoders/decoders (explain).
1581 Bug fixed in DeleteRequest.
1583 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1585 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1587 Added SOIF syntax (using private OID for now) to retrieval module and client.
1589 Added Update extended service.
1591 Added SearchResult-1 additional info structure.
1593 Added optional CCL (ISO8777) interpreter as separate module. Available
1596 --- 1.2 1996/6/10 (1st anniversary release)
1598 Added Summary record syntax. Lightly tested.
1600 Added OPAC record syntax. Untested.
1602 Added ResourceReport service encoders/decoders. Untested.
1604 Fixed bug in z_Unit - wrong tagging on unitSystem.
1606 Fixed bug in the DiagRecs decoder.
1608 Added options for max PDU size and session timeout to frontend-server.
1610 Added documentation of query-language parsers and other supporting utilities.
1612 [frontend-server] Added Attribute set to the bend_scanrequest API.
1614 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1615 surrogate diagnostics were generated.
1617 [retrieval] Allow multiple local values for attribute.
1619 [retrieval] Allow multiple attributes per element in .abs files. index type.
1621 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1623 --- 1.1pl2 1996/4/10
1625 Minor changes, mostly specific to Zebra's requirements (retrieval)
1629 Repaired bug in frontend server when running multiple listening
1630 endpoints in dynamic mode.
1632 z_External() now won't break if a known, ASN.1 value comes encapsulated
1633 in an octet-string. The value will pass through unmodified in an Odr_oct.
1635 Added a bit of code to the demo client to decode & display
1636 ASN.1-structured records represented in the octet-aligned branch of
1637 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1639 Added z_ext_getentbyref() to the ASN module. Doc updated.
1641 * Completed the SCAN definition in the ASN module. This may break SCAN
1642 code based on older YAZ-versions at compile-time. The fix is easy -
1645 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1646 under the SCAN definition. Remember to initialize this, server-people.
1648 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1649 that this does not extend to ODR and ASN.
1651 Comstack allows insertion of established socket (primarily for
1652 inetd-operation of servers). Doc updated.
1654 Front-end server can now start from the inetd in TCP mode. Doc
1657 --- 1.0pl4 1996/1/24
1661 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1662 the rank and record number.
1664 Adjustments to the frontend server.
1666 Fixed diagnostic BER dumper. It ignored the file argument.
1670 Various changes to retrieval module.
1672 Changed the union discriminators of the protocol files from enums to
1673 ints paired with #defines.
1675 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1678 *Changed operator in the RPN structure to 'roperator', again to avoid a
1681 Fixed problems in Explain decoders/encoders.
1683 --- 1.0pl2 1995/12/6
1685 Memory bug in log module fixed.
1687 --- 1.0pl1 1995/12/5
1689 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1691 Bug in Explain DatabaseInfo module fixed.
1693 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1697 The shift to v1.0 signals that we now consider the *core* functionality
1698 of YAZ reasonably stable (the core being more or less equivalent to
1699 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1700 tested (Explain not at all - though that will happen soonish).
1702 Minor changes to code to support Windows port.
1704 Various minor changes after we're getting to use GRS-1 & co. more.
1706 Added Espec-1 format.
1708 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1709 of the protocol and it cannot be selected when encoding (maps into 'string'
1710 when decoding). Needed to talk to some servers.
1712 Demo client can request simple element set names.
1714 Added Diagnostic Format encoders/decoders.
1716 Added simple Close handling to frontend server (no hooks for resource
1717 reporting yet), and demonstration client.
1719 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1721 --- 1.0b3 1995/08/24
1723 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1724 handled incorrectly when records were requested in the searchResponse. This
1725 will only affect you if you use the frontend-server.
1727 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1728 Test-client will ask for and print GRS1. Ztest will return dummy records
1731 Added Explain encoders/decoders to the service-level API. Untested.
1733 Added Extended Services: Item Order encoders and decoders to the Service-
1734 level API. Untested. We could use a recent copy of the pertinent bits
1735 of the ILL protocol to add those bits.
1737 Added diagnostic format 1 encoders/decoders to the service-level API.
1740 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1741 odr_cons.c, which causes a more correct output.
1743 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1744 was always set to 0 when no records were requested in the searchRequest.
1746 * Added better external-handling. This shouldn't harm old code that
1747 *encodes* externals. It can break code that looks for a
1748 'single-ASN1-type' representation, since those types that are known
1749 are now decoded immediately. Look at the SUTRS sample code in
1750 seshigh.c and client.c. Documentation updated.
1752 Handling of structured records in bend_fetchresponse. Length -1 marks
1753 structured record, type is deduced from format field.
1755 --- 1.0b2 1995/06/27
1756 Fairly quick maintenance release to add SUTRS support.
1758 Fixed handling of SUTRS records in the demonstration client.
1760 * Added format field to the bend_fetchrequest and bend_fetchresponce
1761 structures of the backend API (frontend server). When the record is
1762 returned, the value of the format field is mapped to an OID. The
1763 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1764 of the record. The special value VAL_NONE in the bend_request means
1765 that no specific format was requested by the client. Documentation
1766 updated accordingly. Test server (ztest) will return a fixed dummy
1767 SUTRS record if your client requests SUTRS.
1769 Documentation updated accordingly.
1771 You can now set external libraries and RANLIB support in the top-level
1775 First public release.
