1 New facilities for the MARC module. The reading - and writing of
2 content are separate methods for the yaz_marc_t handle. The following
3 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
4 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
5 format). Write functions have prefix yaz_marc_write_.. The existing
6 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
7 available. Removed support for OAI-MARC and simplexml (not the
10 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
11 to be returned for this connection.
15 Allow multiple languages and charsets to be specified with
16 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
17 negcharset iso-8859-1,utf-8
19 Translation of proximity nodes from CQL into PQF now works.
21 Moved to automake 1.8, 1.9.
23 Added function yaz_log_set_handler which allows a log handler to be
24 installed. This handler will be called for all log messages. Output
25 to file is also produced; but that can be disabled by passing NULL
26 fname to yaz_log_init_file.
28 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
30 For SRW (including GFS), accept application/soap+xml as content-type
33 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
34 produces NO stylesheet reference even if a default stylesheet is specified
39 Updated Windows package to include yazd.dll + yazd.lib for the
40 Development component.
42 If the environment variable YAZ_LOG is set, then it is used as a
43 string indicating the default level of logging to use if not
44 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
45 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
46 used as before. So, for example, to omit warnings from YAZ logging,
49 cql_transform() now map structure and other attributes before indexes,
50 so that index-specific structures and other attributes can override
51 defaults. So now a combination of mapping specifications such as:
53 index.dc.date = 1=date-modified 4=5
56 cql_transform() now also respects the "always" mapping specification,
57 which establishes an initial set of attributes to be used for all
58 terms except where overridden by more specific attributes associated
59 with the index, relation or modifier.
61 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
62 which mode to use; one of "post", "get" or "soap" (SRW, default).
64 Fixes for yaz_iconv routines: changed trie-based character set conversions
65 to use only non-negative values for bit fields due to Sun's C compiler not
66 supporting negative values.
68 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
69 sequences where not read correctly. Fix by Rustam Usmanov.
71 Updated win/makefile to use options, settings which makes things
72 compile with VS C 2005.
76 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
78 In ZOOM socket code, use select instead of poll on MacOSX.
80 ZOOM-C now support client-side compilation of CQL into RPN that is
81 sent to the server, enabling CQL to be used against all Z39.50
82 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
83 ZOOM_query object, and submit it using ZOOM_connection_search().
84 The CQL-to-RPN translation uses a configuration file, the name of
85 which must be specified in the Connection's "cqlfile" option.
87 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
88 function, which takes as its start-term parameter a ZOOM_query object
89 (which may have had either CQL or RPN set into it).
94 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
95 GFS to support this as well. Backend handler, bend_srw_update, does the
96 update work. Code contributed by Ko van der Sloot.
98 Allow retrieval of Search Result-1 information in ZOOM by the use of
99 options that are attached to a result set. ZOOM documentation updated
102 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
103 UTF-8 conversion. Patch by Raj Patel.
105 Added option -m to GFS to control formatting of timestamps in log file.
107 Added 'exit' as synonym for 'quit' in yaz-client
109 Added support for specifying SRW resultSetId + resultSetIdleTime in a
110 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
111 for the new members. Patch by Ko van der Sloot.
113 Added support for SRU POST. It is supported for content-type
114 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
116 Do not build the separate Multi-threaded (MT) library libyazthread.la.
117 Instead make the library libyaz.la multi-threaded. Threading as a whole
118 can still be disabled by configure option --disable-threads. Previosly,
119 with older GLIBCs there were problems with MT libs under Apache. This
120 has now been fixed a long time ago.
122 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
125 CQL module modified to be case insensitive for relations/indexes/operations.
127 Fixed bug in CQL transform code: incorrect value relationModifieder
130 Added 'show all' command for yaz-client which retrieves all results
133 Added new yaz-client, xmles, which takes a (private) OID and
134 a document to be sent as an extended service request.
136 Describe new yaz-client commands wait_response and set_auto_wait.
138 Increase TCP/IP listener backlog from 3 (which I am guessing was
139 copied from the SunOS manual entry way back when) so SOMAXCONN, so
140 that the socket will queue as many incoming connections as it's able
141 to handle ongoing connections. In other words, it will never now
142 refuse a connection that it would be able to handle merely because
143 it's not got around to accepting() enough of the pending connections
144 yet. This is the behaviour anyway under Linux, where the listen()
145 argument is ignored; but not under BSD and on systems such as
146 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
147 YAZ-based servers should now be uniform across operating systems in
150 yaz-marcdump uses 64-bit file access on some systems. This is enabled
151 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
152 This allows yaz-marcdump to read large MARC batches (>2 GB).
154 Modified all YAZ source files - except the source which is auto-generated
155 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
158 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
159 corresponding to the existing *_setl() function. These allow option
160 values containing arbitrary valuues.
162 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
163 ZOOM_resultset_sort() in new applications. Its behaviour is identical
164 except that it returns an indicator of whether or not the sort
165 criterion was accepted (0 for OK, -1 for invalid).
169 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
170 MARC output rather than returning "new" buffer.
172 yaz-client warns about unknown init options.
174 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
178 Added support for SRW sort in Generic Frontend Server. Patch
179 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
180 sortKeys - or NULL if none is provided.
182 Fixed bug #307: It was impossible to specify indefinite/no timeout
183 for ZOOM_event. Special timeout value -1 now means indefinite timeout
186 Added support for multiple languages and charsets to be specified in
187 ZOOM. Each charset/language is separated by a blank. If negotiation is
188 in effect in init-response, Option
189 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
190 Code based on patch by Vasiliy Osadchuk.
192 Fixed bug #306: infinite recursion that occurred when calling
193 yaz_log_level_init as the first call (before other log level or
196 Fixed bug in scan handling in front end server: if preferred-Position-In-
197 Response was non-present, a NULL pointer referece was performed.
201 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
202 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
203 now defined for all those error codes. So instead of putting 109 in
204 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
205 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
207 Modified the yaz-marcdump utility to skip garbage bytes between MARC
210 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
212 Program yaz-client now exits and produces an error message if multiple
213 Z39.50 servers are specified on the command line (none or one allowed
216 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
221 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
223 Fixed bug #272: Preserve spacing for CCL terms.
227 Added support for virtual hosts and multiple backend servers for
228 the YAZ frontend server. The configution is XML based and
229 support specificition of CQL to RPN mappings and explain information.
230 See section "Virtual Hosts" in the YAZ manual.
232 Extended OPAC display utility. OPAC display utility renders
233 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
234 to supplement yaz_marc_decode_wrbuf.
236 Fixed a bug in MARC decoder that could caused it to crash for some
237 invalid MARC records. More diagnostics and warnings where added in
238 XML output (warnings, etc are stored in comments).
240 --- 2.0.34 2005/02/08
242 Fixes for UNIX domain sockets. Bug #261.
244 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
246 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
247 Added yaz_marc_subfield_str which defines subfield lead string which is
248 used in YAZ_MARC_LINE format. Default string is blank+$. Added
249 yaz_marc_endline_str which defines end of fields string used in
250 YAZ_MARC_LINE format. Default string is newline.
252 Experimental support for MarcXChange. This format can be produced
253 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
254 http://www.bs.dk/standards/MarcXchange.xsd
256 Added yaz-client commands scansize that sets maximum number of
257 entries to be returned by scan.
259 --- 2.0.32 2005/01/11
261 Added support for SRW scan in yaz-client and Generic Frontend Server.
263 * Added whereInList member to SRW Scan Term.
265 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
267 Fixed NMEM system to return aligned blocks on the smallest boundaries
268 that are suitably aligned for all possible types on the particular
269 architecture YAZ is being built for.
271 --- 2.0.30 2005/01/04
273 Fixed numerious warnings that was issued with newer versions of GCC.
275 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
276 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
279 Make YAZ Generic Frontend Server slightly faster.
281 Enhance (and reduce) logging for Generic Frontend Server.
283 Revert YAZ log system so that it flushes every write operation
284 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
286 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
287 instead of LOG_, due to name clash with syslog(3). LOG_ are still
288 present. New applications should define YAZ_USE_NEW_LOG=1 - this
289 will effectively disable old definitions.
291 --- 2.0.28 2004/11/09
293 Added yaz_log_time_format which specifies log format using
296 Added yaz_log_module_level which returns mask for a module. Value
297 is non-zero mask a if module is enabled; zero if disabled.
299 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
300 in include/yaz/cql.h.
302 Fixed bug #176: Dont throw diagnostics on empty SRU args.
304 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
306 Fixed bug #172: RPM builds does not enable SSL.
308 Doxyfile.in part of dist. Doxyfile generated by configure.
310 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
311 are given and the corresponding component does not exist.
313 Extend CCL documentation in YAZ reference. Describe r=r.
315 --- 2.0.26 2004/10/01
317 Fixed MARC->MARCXML conversion to properly deal with
318 fields, subfields, indicators having non-ASCII characters.
320 Fixed MARC->MARCXML conversion so that ASCII control characters
321 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
324 Added YAZ GFS support for conversion from Z39.50 surrogate
325 diagnostics to SRW surrogate diagnostics.
327 Bug fix: YAZ GFS did not return schema in explainResponse.
329 --- 2.0.25 2004/09/30
331 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
332 now converts recordSchema to elementSetName as well as schema URI.
334 Fixed bug in COMSTACK that prevented HTTP request packages from being
337 --- 2.0.24 2004/09/29
339 Added CCL facility r=r "range" which is similar to r=o "ordered" but
340 does not require white-space before and after the dash in a range, e.g.
341 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
344 Fixed a few AC_TRY_LINK configure tests that did not operate properly
345 due to new GCC removing "redundant" code.
347 Added yaz-client commands scanpos and scanstep that sets preferred
348 position and step-size for scan.
350 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
352 Added CCL utility ccl_qual_buf which parses one or more CCL
353 spec lines in a buffer.
355 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
356 of name and value - ignoring empty lines and comments.
358 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
360 Added odr_get_element_path which returns current element path for an
361 ODR handle. This utility is useful in error handling or user-defined
364 Added ODR_PRINT utility odr_set_stream which is is a more generic
365 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
366 to a write function and pointer to close function. The close function - if
367 non-NULL - will be called during odr_destroy.
369 Fixed bug in CCL parser where truncation char was not removed from
370 right side when truncation=both was in effect.
372 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
375 --- 2.0.23 2004/08/11
377 Fix buffer overrun in CQL parser when dealing with proximity (%).
379 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
380 to UTF-8/UCS conversion is now only based on codetables.xml.
382 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
384 --- 2.0.22 2004/08/06
386 Add support for more "commit changes" in ZOOM (uses Extended Services).
388 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
391 Yet another small fix for configure of SSL.
393 --- 2.0.21 2004/05/14
395 Fix SSL libs for configure when --with-openssl=DIR is given.
397 --- 2.0.20 2004/05/10
399 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
401 SSL comstack now uses yaz.pem certificate file on server side
402 by default. Certificate filename can be configured by calling
403 comstack function cs_set_ssl_certificate_file before cs_bind is used.
405 Fix bug regarding multiple calls to ZOOM_connection_connect.
407 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
409 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
410 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
412 ZOOM now allows inspection of X509 peer certificate for verification.
413 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
415 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
416 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
417 as "modular" but it simplifies things.
419 Added cs_get_peer_certificate to that returns peer X509 PEM.
421 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
422 NULL if SSL is unavailable.
424 Documentation about MARC decoding tools.
426 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
428 --- 2.0.19 2004/03/30
430 Rename CHANGELOG to NEWS to follow GNU style packing.
432 Fix bug with missing initialization of member in init_diagnostics.
433 This bug affects threaded version of GFS server.
435 --- 2.0.18 2004/03/20
437 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
440 Ensure zlib.dll is packed with Windows install.
442 --- 2.0.17 2004/03/17
444 Fix encoding of xsd:string to use text instead of CDATA.
446 Fix endless loop in CQL parser with unbalanced ".
448 Use a more compact way to store MARC-8 conversion tables.
450 --- 2.0.16 2004/03/16 Debian only
452 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
455 Update CQL parser to use new CQL 1.1 modifiers for booleans and
460 --- 2.0.15 2004/03/01
462 Another fix for decoding of XML packed records.
464 --- 2.0.14 2004/02/25
466 Fixes for Chunked encoding. White space not ignored after length spec.
468 Update NS and use default NS for SRW diagnostic elements.
470 --- 2.0.13 2004/02/23
472 Implement ZOOM_resultset_cache_reset which resets record cache.
474 Implement ZOOM_resultset_sort which sorts a result set.
476 Implement chunked HTTP transfer.
478 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
480 --- 2.0.12 2004/02/16
482 Added member 'schema' to bend_explain_rr structure so that backend
483 can specify explain record identifier. Defaults to Zeerex 2.0.
485 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
487 --- 2.0.11 2004/02/16
489 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
492 Added init command for yaz-client which sends "extra" init request.
494 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
495 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
497 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
499 Make ZOOM error code for "invalid query".
501 Fixed compilation for SSL which wasn't properly enabled for all platforms.
503 --- 2.0.10 2004/02/05
505 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
508 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
510 Added option -p <file> to make Generic Frontend Server to write PID file.
512 Added option -D to put Generic Frontend Server in background on its own.
514 Make ZOOM C recognize option "password". If unset, "pass" is used
515 (for backwards compatibility).
517 Fixed a bug in Generic Frontend Server that could make it crash if a
518 client sets characterSetNegotation bit, but didn't pass negotiation stuff
521 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
522 Must be issued before open, in order to be in effect.
524 --- 2.0.9-6 2004/01/12 Debian/Windows
526 Make the SRU server more picky WRT unknown params, etc.
528 Bug fix: ZOOM scan response didn't return displayTerm - when present.
530 New YAZ client command, options, that sets Z39.50 options.
532 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
533 options from a string of tokens (one token for each option bit).
535 Update SRW diagnostic code messages.
537 --- 2.0.9-5 2004/01/07 Debian/Windows
539 Handle user defined stylesheet for SRW/SRU.
541 --- 2.0.9-4 2004/01/06 Debian/Windows
543 Fix bug in decoding of Content-Length.
545 --- 2.0.9-3 2004/01/06 Debian/Windows
547 Fix a bug with decoding of XML packed records.
549 --- 2.0.9-2 2004/01/05 Debian only
551 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
553 Fix bug in SRW/SRU diagnostics decoding.
557 Fixed bug in Generic Frontend Server which could drop records exceeding
558 preferred message size. Reported and fixed by Irina Dijour.
560 Fixed calculation of package size for structured records in Generic
561 Frontend Server. Reported and fixed by Irina Dijour.
563 Fixed namespace for SRW/SRU diagnostics.
565 Fixed SEGV in yaz-client that occured for HTTP connection errors.
569 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
570 this version is incompatible with version 1.0 and older YAZ SRW/SRU
573 CQL changes to reflect recent changes to the specification:
574 * Documentation talks about context sets instead of index sets.
575 * Documentation talks about indexes instead of qualifiers.
576 * The CQL-to-PQF transformer's configuration file now uses
577 "index.set.name = <attributes>" instead of the old form
578 "qualifier.set.name = <attributes>". (Both forms are still
579 understood but the latter is deprecated.)
580 * CQL terms with no explicit index specified are now interpreted as
581 cql.serverChoice instead of srw.serverChoice (which of course
582 behaves exactly the same.)
586 MARC conversion can now generate ISO2709 output in another
587 character set. yaz-marcdump uses this facility if you invoke it
590 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
591 functions from there can be used from C++.
595 Frontend server now transfers memory from decoded packages to stream
598 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
599 references to show up.
601 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
602 the ZOOM Abstract API. The older names for the same options are still
603 also supported for the benefit of old applications.
605 ZOOM-C supports "implementationId" and "implementationVersion" options
606 to go along with "implementationName". These allow the user code to
607 specify identification strings to be sent to servers.
608 Add OID for the new ExtLite attribute set.
610 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
611 as requested/supplid by Ere Maijala <ere@atp.fi>
613 For generic frontend server, reverse the order of
614 "toolkit-supplied / application-supplied" strings sent as implementationId,
615 Name and Version. Also, remove the spaces around the slash. This brings
616 the GFS in line with the behaviour of ZOOM-C on the client side.
618 Add function ZOOM_scanset_display_term.
620 yaz-client shows scan displayTerm if present.
622 Utility yaz-iconv is now installed by default along with the man page
625 Extend configure check for OpenSSL to use pkg-config where available (such
628 Incorporate patch by Morten Bogeskov which allows a Unix file socket
629 server to specify uid/gid/mask for socket using the format
630 unix:[user=uid,][group=gid,][umask=mask,]file=path
631 If file= is omitted the existing format is assumed, e.g.
633 in which case the mask is 0666 (rw for everybody).
635 Major restructure of YAZ source. All source in libyaz is in src directory.
636 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
637 util (utility programs such as ASN.1 compiler, yaz-marcdump).
639 Added man page for utility yaz-marcdump (used to be called marcdump).
640 yaz-marcdump is installed by 'make install'.
642 Fixed a memory leak in Generic Frontend Server that occurred when decoding
643 of incoming package failed.
645 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
647 Change prototype of odr_perror: add const to message string.
649 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
651 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
652 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
653 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
654 DNS lookup. There should not be any compatibility problems with this
655 assuming that blocking=1 or 0 is used.
657 Fix bad reference in UNIX comstack in function cs_addrstr.
659 Fix for compilation on AIX.
661 The generic front-end server (server/seshigh.c) now supports returning
662 Init diagnostics to the client in User-information-field, in
663 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
668 Allow any CQL relation (not just all,any,exact,scr).
670 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
671 that features the same UI.
673 Implemented command update0 in YAZ client which is equivalent to
674 update but uses old of Ext Update ASN.1.
676 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
677 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
678 Previously no OID was used for this info.
680 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
681 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
682 returns 'malformed search term' otherwise.
684 SortResponse member resultCount now set to NULL in sort handler of
687 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
690 Add three new utility functions for translating OIDs between various
691 formats -- symbolic name such as "Usmarc", minus-1-terminated int
692 arrays and dotted strings such as "1.2.840.10003.9.5.1":
693 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
694 char *oid_to_dotstring(const int *oid, char *oidbuf);
695 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
697 Reverted modifications for ES Update definition for z_IU0Update
698 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
699 is back to YAZ 2.0.2.
701 String value attributes for CCL parser.
703 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
704 which their FirstSearch server returns in Init responses, sometimes
705 carrying useful diagnostic information when Init fails. This has the
706 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
707 "z39.50/oclcui.asn", where its definition is somewhat different from
708 what OCLC document on their web-site, as required to interoperate with
711 Support for anonymous authentication in yaz-client. Use the command
714 * Fix the OID of the Index Data-local "admin" Extended Service from
715 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
716 the 1000, which indicates a locally-defined OID, was a mistake.
720 Fix CCL directive @case handling so that it affects string match for
721 both CCL keywords and qualifiers.
723 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
724 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
725 Decoder has been updated with ASN.1 changes as listed in
726 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
727 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
728 z_IUUpdate, remains unchanged.
730 ZOOM_record_get may now return a record in a specific character set.
731 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
732 "from" is the character set of record as returned by target. "to" is
733 the character set to be returned. If omitted, "to" is UTF-8.
735 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
737 New ODR utility, odr_getelement, which returns name of element for
738 which encoding/decoding failed.
740 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
741 in cases where a required element was omitted.
743 Bug fix: some MARC8 sequences were not converted.
745 New ZOOM option "step" which specifies number of records to be
746 retrieved in one chunk. Used in conjunction with "start" and "count".
748 SRW support for yaz-client. Use scheme http: to use it, e.g.
751 yaz-client no longer does (un)intelligent character set conversions
752 by default. Can be enabled with charset and marc_charset commands.
754 xmalloc trace fix for 64-bit systems such as DEC alpha.
756 Solaris 2.6 compile fix.
758 New function, cql_strerror() translates SRW error codes, as returned
759 by cql_transform_error(), into human-readable English strings. Used
760 in yaz-client diagnostics when appropriate.
762 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
763 converts it into a type-1 query which is sent to the server. This
764 makes CQL available for use with all Z-servers, as opposed to the tiny
765 minority that can handle CQL queries themselves.
769 New Debian package layout similar to the Redhat Package layout.
771 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
772 and search result respectively.
776 Redhat package is now several packages: libyaz (runtime libraries),
777 libyaz-devel (development and documentation, and yaz (utility programs).
778 Package spec file by Morten Bøgeskov.
780 New member 'schema' in struct bend_fetch_rr which the name of requested
781 schema (SRW/SRU) for record (or NULL if none was given). The fetch
782 handler MAY set this to reflect the schema of the returned record.
784 New member 'display_term' in struct scan_entry. GFS now sets member entries
785 and allocates scan entries to be filled by user scan handler. In previous
786 version, entries member was allocated by the scan handler. That still works,
787 but the GFS will ignore member display_term - assuming it was NOT set by
788 the handler. The fact that the GFS now allocates the entries both allows
789 for new members and makes a scan handler easier to write.
791 Fix CQL lex buffer overflow.
793 SRW/SRU recordPacking. For SRW default recordPacking is string. For
794 SRU default recordPacking is string.
796 SRU protocol support for frontend server.
798 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
800 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
802 Added scan for the ZOOM shell (zoomsh).
806 * String Identifers for Schemas (Amendment 5).
807 http://lcweb.loc.gov/z3950/agency/amend/am5.html
808 Old definition for schema
809 Odr_oid *schema; /* OPT */
814 Z_InternationalString *uri;
815 #define Z_Schema_oid 1
816 #define Z_Schema_uri 2
819 * resultCount parameter to Sort Response (Amendment 1).
820 http://lcweb.loc.gov/z3950/agency/amend/am1.html
822 Support for SRW 1.0 over HTTP. This is an optional feature and
823 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
826 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
827 on the same port. SRW SearchRetrieveRequests are mapped
828 to bend_init,bend_search,bend_fetch,bend_close.
830 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
832 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
833 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
835 ZOOM connections are SRW based if schem http is used for hostname
836 in connect, e.g. z = ZOOM_connection_new("http://myserver");
837 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
839 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
840 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
841 distance=n, order=true/false, relation=le, prox unit=word. If
842 n is omitted, distance 1 is used.
844 Fixed problem with C compiler include path in wrong order.
846 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
847 on Solaris. Patch from Ko van der Sloot.
849 New MARC decode API. All new functions operate on a yaz_marc_t
850 handle. The most important new functions are: yaz_marc_create,
851 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
852 decode and destroy respectively. Decoder can produce formats
853 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
854 include/yaz/marcdisp.h.
856 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
857 to UTF-8, UCS-32, wchar_t or Latin-1.
859 * Prototypes for yaz_iconv_-functions moved to separate header
860 include/yaz/yaz-iconv.h.
862 Make a few private functions 'static' in unix.c. This prevents
863 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
865 For ZOOM connection, the options targetImplementation{Id,Name,Version}
866 are set when Init Response is received.
868 New function ZOOM_connection_error_x similar to ZOOM_connection_error
869 but returns diagnostic set as well.
871 New function yaz_strerror which is a portable wrapper for
872 strerror/strerror_r/GetLastMessage.
874 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
875 is returned for MARC. If type is "oai", then OAI MARC is returned.
877 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
882 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
884 Fix bad race conditions on SIGTERM and terminate gracefully in
887 Move retrieval (data1) module to Zebra since nobody seems to be
890 Add GRS-1 render for ZOOM using same format as yaz-client.
894 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
896 Fix broken ESpec handling in data1 module.
898 SGML reader parses comments and makes them part of the data1 tree.
900 Added several type casts so that YAZ compiles as C++ code.
902 ZOOM didn't handle PDU encoding failures properly.
904 Added more Bib-1 diagnostics (approved extensions).
906 GNU configure: better check for iconv.
908 More portable use of accept, getpeername. Check for socklen_t. Use
909 int/size_t if socklen_t is not defined.
913 PQF parser rejects bad queries - including those with extra
914 characters in them. PQF parser used to silently ignore that.
915 Cleaner API for PQF added, which allows you to get detailed
916 error information for bad queries (see yaz/pquery.h).
918 Fixed bug in ZOOM_record_get for type "database".
920 Implemented mini iconv library supporting conversions between
921 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
923 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
927 Fixed ZOOM C record cache so that preferredRecordSyntax and
928 elementSetName is used to check for already fetched records.
932 Added three members in bend_initrequest structure to facilitate
933 character set negotiation.
935 Fixed a bug in frontend server that could cause indefinite
936 loops under rare conditions.
938 Revised character set utilities (charneg.h) so that encoding
939 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
941 For PQF, directive @term <type> sets term type for Scan/Search.
942 Here <type> is general, string, numeric, null. The term type
943 is inherited - just like @attr.
945 New call odr_set_charset that sets character set conversion for
946 international-strings on a ODR stream. Prototype is:
947 int odr_set_charset(ODR o, const char *to, const char *from);
948 The InternationalString is still represented as C string in YAZ
949 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
950 won't). On the protocol level, you can use any encoding.
952 Support for UNIX sockets in ZOOM.
954 Solaris recv sometimes returns errno == ENOENT. It is treated as
955 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
957 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
958 both client and server. Code by Morten Bøgeskov.
962 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
963 that they can be used directly from Visual Basic. You must recompile
964 your windows APP if you're using ZOOM.
966 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
967 Commands "lang" and "charset" sets language and character set respectively.
968 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
969 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
971 Attributes from multiple CCL fields may be OR'ed rather than merged
972 using directive "@field or". Fields are still merged by default -
973 equivalent to "@field merge".
975 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
978 Fixed bug in zget for parameter ExtendedServicesResponse.
984 Added PQF feature: '@attr type=value' may be written as '@type=value'.
986 Client displays USR.1:SearchResult-1 (hits per term).
988 Additional Search Info for search in Generic Frontend Server.
990 Fixed CCL parsing of "field=s".
992 WIN32 installer - using the excellent NSIS software from nullsoft.
994 Fixed CCL parsing of "field = - <number>".
996 Added function yaz_marc_decode that decodes MARC for line mode
997 display or XML (similar to that used by JZKit).
999 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1000 Z39.50. But ISO/ILL was, however.
1002 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1003 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1005 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1006 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1008 --- 1.8.5 2002/02/03
1010 New YAZ client features: Command completion and new commands:
1011 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1012 Code provided by Jacob Poulsen.
1014 New call oid_trav, that visits all registered OIDs via callback.
1016 Function ZOOM_record_get now returns const char pointer rather than
1017 void pointer. It saves a lot of type casts.
1019 For YAZ client, command "auth" now allows you to set authentication
1020 in IdPass style. It is enabled when three tokens are given - order
1021 is user, group and password.
1023 Fix memory leaks in MARC record handling for ZOOM.
1025 New option for YAZ client, -k <kilobytes> that sets
1026 maximum record size. Similar to -k option for generic frontend
1027 server and yaz-ztest.
1029 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1031 Prefix query parser reports "fail" when bad attribute set is given.
1033 Fix in MARC decoder. Proximity logging. Fix for attribute set
1034 in scan handler for server. Patches by Shigeru Ishida.
1036 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1039 Configure option --with-openssl=<dir> now works when a directory is
1040 specified. Patch provided by Morten Bøgeskov.
1042 New option for YAZ client, -u <auth>, that sets authentication.
1044 ZOOM fix: error information was sometimes "missing", since error
1045 was cleared/reset too when it shouldn't.
1047 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1049 --- 1.8.4 2002/01/04
1051 Scan for ZOOM API. New object ZOOM_scanset. New functions
1052 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1053 ZOOM_scanset_destroy.
1055 New ZOOM function, ZOOM_connection_last_event, that returns type
1056 of last event (such as "receive data", "send data", "apdu received",
1059 New ZOOM option, schema, that specifies schema for retrieval.
1061 New CCL feature. Qualifiers can be aliases for one or more
1062 other qualifiers (if more than one is given, OR is used).
1064 ZOOM uses named result sets if target supports it.
1066 Two new YAZ client commands: . (dot, which sources a script of YAZ
1067 client commands), and ! (to execute shell command.). Implemented
1070 Working on Debian packages.
1072 --- 1.8.3 2001/11/19
1074 YAZ client enables named result sets only if target supports it.
1076 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1078 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1079 with key="host" to get same result.
1081 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1082 Function Z3950_resultset_record(s) returns references to records
1083 "owned" by resultset. To become owner use Z3950_record_clone.
1085 Function z_ext_record handles Extended Services. Thanks to
1088 --- 1.8.2 2001/11/12
1090 CCL Parser fix: ignore token comma when dealing with and-lists.
1092 Documentation updates for COMSTACK.
1094 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1095 Changed prototype Z3950_records. For some functions, int parameters
1096 were changed to size_t.
1098 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1101 New MARC decode/display function, marc_display_exl, which properly rejects
1102 non-ISO2709 records. YAZ client uses it.
1104 --- 1.8.1 2001/10/29
1106 Fix bug: local attribute set wasn't set correctly in PQF strings.
1110 * Old Z39.50 codecs no longer supported.
1112 Added ZOOM C binding. See http://zoom.z3950.org/
1114 Renamed states for COMSTACKs to avoid confusion with events.
1116 Implemented cs_look and proper cs_rcvconnect.
1118 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1120 Configure detects POSIX threads on OpenBSD.
1122 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1123 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1125 When error is returned from present handler, non-surrogate diagnostic
1126 is returned in present response (and fetch handler is no longer called).
1128 * Minor adjustments to pquery parser (PQF). Token characters may be
1129 escaped by using backslash (C-style).
1131 PQF parser allows string attribute values to be specified. For @attr,
1132 non-numeric characters after the equal-sign are treated as strings
1133 (e.g. @attr 9=title).
1135 CCL trunction character may be defined (@truncation in file)
1137 * function zget_ExtendedServicesRequest sets waitAction to
1138 waitIfPossible (was wait).
1140 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1143 CCL operator names may be set in field definition files (CCL_bibset).
1144 See ccl/bib1 for an example.
1146 Fixes in ASN.1 compiler for C++ compatibility.
1148 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1149 and "op_or" to avoid conflict with C++.
1151 Fixed problem with GNU readline detection on Redhat 7.0.
1153 Added step-size for Scan backend handler.
1155 Fixed bug that made the frontend server crash when no attribute
1156 set was specified for scan.
1158 Front-end server automatically switches to original working directory
1159 when installed as an NT service. Previously -w had to be specified to
1162 Added extended attributes for retrieval module (data1), so that data1
1163 records carry d1_readXML/SGML attributes. d1_read also supports
1164 null-data rules ( <tag/>)
1166 On UNIX when POSIX threads are available, a separate library libyazthread
1167 is created. Programmers should link with that library and the yaz library
1168 when using threads. The reason for the split was that some applications
1169 on Linux, such as Apache, doesn't work well when using shared objects that
1172 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1173 (or any frontend server) in SSL mode by specifying ssl: followed by
1174 address. Only tested on UNIX.
1176 Added feature for CCL module. Virtual structure s=al or s=ol generates
1177 and-list and or-list respectively instead of phrase search.
1181 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1182 log_mask_str. This was done to avoid name conflicts with other libraries
1183 (such as other PHP extensions).
1185 Added raw OID member for preferred record syntax (request_format_raw)
1186 and returned record syntax (output_format_raw) for backend fetch method.
1188 Config file yaz-config now accepts options so that it returns specific
1189 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1191 Shared library support for UNIX using GNU libtool.
1193 * Modified backend interface. Request/Response struct's replaced by
1194 one read/write C struct. For example bend_fetchrequest and
1195 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1196 Every handler - even search has to be registered in bend_init
1197 handler. This means that the YAZ library no longer refers to
1198 external functions and it makes it possible to make the whole
1199 thing a single DLL/SO.
1201 Added Segment handler for backend server.
1203 Added Zmbol/Zebra administrative functions to YAZ client.
1205 Threaded frontend server on UNIX (when POSIX Threads are available).
1206 Starting the server with option -T enables multi-threading.
1210 Added configure option --enable-comp/disable-comp to control use
1211 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1212 located in sub directory asn.
1214 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1215 in ${exec_prefix}/bin along with the other programs yaz-client and
1218 GNU automake used to maintain makefiles.
1220 Added several OID's.
1222 Changed retrieval module so that we can load records with no abstract
1223 syntax defined. Tagpaths in these records are fully composed of string
1226 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1230 On UNIX, the generated makefile now supports a proper 'make install'.
1231 The prefix can be set via GNU configure to set the install location
1232 (default is /usr/local).
1234 * YAZ programs client and ztest were renamed to yaz-client and
1235 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1236 locations, such as /usr/bin,/usr/local/bin,etc.
1238 * YAZ Header files were moved from include to include/yaz. YAZ Header
1239 files are referred to as include <yaz/log.h> rather than <log.h>.
1240 The YAZ include path (-I ..) is therefore the same as before. Programmers
1241 should update their #include statements or use -Ipath/include/yaz
1242 instead. The main motivation for doing this change is that YAZ header files
1243 can be installed in "standard" locations /usr/include,/usr/local/include
1244 without introducing conflicts, since ALL YAZ header files are stored
1245 in subdirectory yaz (under /usr/include for example).
1247 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1248 rather than project/workspace files. We switched because project files
1249 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1252 Changed name of logging function, logf, to yaz_log, to prevent name
1253 clash with some math-log functions. The YAZ header log.h defines logf
1254 to yaz_log (#define) so there should be no incompatibilities by this
1257 Added bend_start/bend_stop handlers for server. These handler are
1258 called on start/stop of server. For windows they are called whenever
1259 a service is started/stopped.
1261 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1262 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1263 in util/yc.tcl. The auto-generated C code structures are, in a few
1264 cases, incompatible with the old decoders. There are differences in the
1265 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1266 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1267 The preprocessor variable ASN_COMPILED is defined when the compiled
1268 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1269 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1270 wish to use the old encoders/decoders you can specify --disable-yc
1273 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1274 version so that it supports both new - and old version of DB Update
1276 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1277 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1278 change. The name parameter can be set to 0 in which no name is specified
1279 for the construction. The macros odr_implicit and odr_explicit sets name
1280 parameter to zero for the construction involved. New macros
1281 odr_implicit_tag and odr_explicit_tag are similar to the others,
1282 except that a name parameter is added. For programmers' that don't use
1283 ODR they probably only need to change the call to z_APDU and z_External.
1285 Added access control facility by interfacing the TCP wrapper library.
1286 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1287 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1288 name of the daemon and enables the access control as specified in
1289 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1291 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1292 den Dool <H.M.vdnDool@kub.nl>.
1294 Added reference ID parameter to most functions in server API - refer
1295 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1297 Changed name of ccl library to libccl.a (was ccl.a).
1299 Fixed bug in decoder for Explain (Category TargetInfo).
1301 Added support for GNU readline in client. Thanks to Jacob Poulsen
1302 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1304 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1305 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1306 IMPLEMENTATION! This change was made to the development version before
1307 the ZIG decided to retract the amendment. If any users MUST be
1308 compatible with the original Update definition, PLEASE CONTACT US, and
1309 we will include a separate definition corresponding to the old Update
1310 ES. Note that because of the change to the ASN.1 of the
1311 TaskPackageRecordStructure we cannot define a single structure that
1312 will support both versions.
1314 * Added const modifier to buffer parameter for some ODR/BER encoding
1315 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1316 completeWAIS, odr_dumpBER.
1318 Fixed bug in client.c which caused a crash when a scanResponse didn't
1319 contain positionOfTerm.
1321 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1322 * will cause an error in a client if a non-YAZ target sends both a
1323 * list of Scan entries and non-surrogate diagnostics.
1325 Retrieval module enhancements. Tag sets may be typed in the reference
1326 to it. From the .abs-file the "tagset" directive takes a third optional
1327 integer type for the tag set referenced. From a .tag-file the "include"
1328 directive takes a third optional type as well. The old "type" directive
1329 in the tag set itself is still recognized but acts as the default type
1332 Backend interface change. Individual Scan terms returned from bend_scan
1333 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1334 in include/backend.h.
1336 Retrieval module enhancements. Multiple tag sets and attribute sets may
1337 be specified in abstract syntax specs. Revised the error/warning for
1338 logging messages reported by the retrieval module when reading the
1341 Object Identifier system (oid_..) changed. The API is backwards
1342 compatible but the oid-routines now allocates new OID's when needed.
1343 Raw OID's may be specified in oid_getvalbyname.
1345 YAZ now uses GNU configure to generate Makefile(s).
1347 * Minor changes in some of the member names of DeleteResultSetRequest and
1348 DeleteResultSetResponse. See include/proto.h.
1350 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1351 and added member 'languages' in TargetInfo (which was missing).
1353 Changed the way attribute sets are handled in the retrieval
1354 module. These are now cached, just like the abstract syntaxes
1357 Changed YAZ so that it links with compiled ASN.1.
1359 Added Explain-schema definitions and mapping routines. The following
1360 Explain categories have been implemented: AttributeDetails,
1361 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1363 Fixed minor bug in Windows version of Server Library.
1365 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1367 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1369 Added EXTERNAL: UNIverse Resource Report (non-standard).
1371 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1372 ENUMERATED and SET OF.
1374 * Added 'const' to some of the char pointer arguments for the
1375 functions, data1_read_node, data1_getelementbytagname,
1376 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1379 Fixed bug in data1_insert_taggeddata - the last_child member of
1380 parent wasn't initialised.
1382 * Changed data1_read_record and data1_read_node so that the supplied
1383 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1384 doesn't refer to any parts of the "SGML"-buffer.
1386 Fixed bug in server library (Windows version of statserv_remove).
1388 * Changed code so that it compiles as C++. The type definition
1389 of Odr_fun which is a member of Odr_arm was changed. The result is,
1390 that an explicit typecast is needed for the fun pointer when
1391 using Odr_arm - as in:
1392 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1394 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1396 Implemented the new structured date and time definition as approved
1397 by the ZIG. Added schemaId element to the specificTag in Espec-1
1398 (also approved at the last ZIG). Thanks to RVDM.
1400 Added some Object identifiers (RVDM).
1402 Changed the Update Extended Service (RVDM).
1404 Added command "refid" to client which specifies referenceId for
1405 the following requests.
1407 Implemented extended service handling for server. See ztest.c
1408 for an example as well as backend.h. New handlers are registerd
1409 in the Init handler.
1411 * Changed interface for sort in server.
1413 Added new members to statserv_options_block. It allows a server
1414 to read options from another source than just the command line. Thanks
1415 to Charles Woodfield.
1417 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1418 renamed to zboolean. Some C++ compilers complained about the name.
1420 Minor changes to gils.abs. Added index 's' (sort) on title
1421 and date/time-last-modified.
1423 --- 1.4pl2 1998/1/30
1425 Fixed bug in server library regarding inetd mode (-i). This bug
1426 was introduced by release 1.4.
1428 --- 1.4pl1 1998/1/29
1430 Added sort facility in client and backend server interface.
1432 Fixed problem with dependencies in Makefile(s).
1434 Fixed bugs for encoders/decoders of extended services and
1437 Implemented sub-tree feature for schemas. Sub-trees are
1438 referenced in *.abs-files. See explain.abs for an example
1439 of the use of this feature.
1441 Modified bib1.att; local attributes for ANY didn't include
1442 ANY itself (only affects use of the retrieval module).
1444 Fixed bug in plain SGML reader in function data1_read_node:
1445 tags with prefix "var" was incorrectly interpreted as variants.
1447 Added feature "sub-schemas" to enable references to - and definitions
1448 of - group of elements.
1450 * Removed member parent from type data1_element (in data1.h).
1452 Implemented function odr_nullval() that returns the value of
1455 * Removed member num_children from data1_node (in data1.h).
1457 Made NT service interface part of the server library. The
1458 function statserv_main uses the NT service when required and
1459 calls the statserv_start / statserv_close routines.
1461 Routine zget_SearchRequest and zget_PresentRequest fills
1462 resultSetName/Id member with "default" instead of "Default".
1464 Fixed memory leak in server. Request queue member wasn't freed.
1466 Fixed nmem_exit so that memory is freed.
1470 Revised the CCL parser utility to be thread safe.
1472 Added function, oid_ent_to_oid, to replace the function
1473 oid_getoidbyent, which is not thread safe.
1475 * Added nmem_init and nmem_exit to initialize and release
1476 NMEM resources. Function nmem_init should be called once in the
1477 initial thread before NMEM/ODR is used. statserv.c and client.c
1478 have been changed accordingly. The change was necessary to make
1479 NMEM thread safe. The NMEM memory pool is shared amongst threads
1480 in a process. Unix-based applications will still work fine without
1483 Added NT Services interface for the the Z39.50 (statserv) Server.
1484 Refer to the ztest.c source on the usage.
1486 Windows 95/NT port using MSVC5.0. Project files are included in the
1489 * Defined new 'global' handle for the retrieval (data1) system. The
1490 new handled, data1_handle, describes the state of the data1 system.
1491 This handle is passed as first argument to virtually all
1492 data1 related routines. The functions data1_create and data1_destroy
1493 creates and destroys a data1 handle respectively.
1495 Added ODR encode stream member to all backend request structures
1496 init, search, scan etc. This stream should be used to allocate all
1497 memory used for the response when thread safe operation is needed.
1499 Changed the comstack utility, cs_addstr, to be thread safe. The
1500 returned hostname string returned by the function is now part the
1503 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1504 function. The cs_straddr takes a COMSTACK handle as argument, so this
1505 function must be used after cs_create and before bind/connect.
1506 This function is thread safe.
1508 Moved test server to 'ztest' directory - generic server code still
1509 in 'server' directory.
1511 Made prefix query (pquery.c) utility thread safe.
1513 Added new function modifier YAZ_EXPORT to 'export' public DLL
1514 functions when using windows (see include/yconfig.h).
1516 Added definitions to the OID database (util/oid.c) (RVDM).
1518 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1520 Added call to ccl_rpn_delete in client program.
1522 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1523 release of RPN structure.
1525 Added support for C++, headers uses extern "C" for public definitions.
1526 With input from RVDM.
1528 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1529 Thanks to Ronald van der Meer (RVDM).
1531 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1533 Added support for private extensions to the OID database
1534 (oid_setprivateoids()). Thanks to RVDM.
1536 Added optional, physical ANY (key replication)
1538 Fixed null-reference problem in GRS-1 output filter.
1540 Proximity operator added to Prefix Query Format (PQF).
1542 In test client command "base" accepts multiple databases.
1544 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1548 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1550 Smallish bug-fixes in the new encoders/decoders (explain).
1552 Bug fixed in DeleteRequest.
1554 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1556 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1558 Added SOIF syntax (using private OID for now) to retrieval module and client.
1560 Added Update extended service.
1562 Added SearchResult-1 additional info structure.
1564 Added optional CCL (ISO8777) interpreter as separate module. Available
1567 --- 1.2 1996/6/10 (1st anniversary release)
1569 Added Summary record syntax. Lightly tested.
1571 Added OPAC record syntax. Untested.
1573 Added ResourceReport service encoders/decoders. Untested.
1575 Fixed bug in z_Unit - wrong tagging on unitSystem.
1577 Fixed bug in the DiagRecs decoder.
1579 Added options for max PDU size and session timeout to frontend-server.
1581 Added documentation of query-language parsers and other supporting utilities.
1583 [frontend-server] Added Attribute set to the bend_scanrequest API.
1585 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1586 surrogate diagnostics were generated.
1588 [retrieval] Allow multiple local values for attribute.
1590 [retrieval] Allow multiple attributes per element in .abs files. index type.
1592 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1594 --- 1.1pl2 1996/4/10
1596 Minor changes, mostly specific to Zebra's requirements (retrieval)
1600 Repaired bug in frontend server when running multiple listening
1601 endpoints in dynamic mode.
1603 z_External() now won't break if a known, ASN.1 value comes encapsulated
1604 in an octet-string. The value will pass through unmodified in an Odr_oct.
1606 Added a bit of code to the demo client to decode & display
1607 ASN.1-structured records represented in the octet-aligned branch of
1608 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1610 Added z_ext_getentbyref() to the ASN module. Doc updated.
1612 * Completed the SCAN definition in the ASN module. This may break SCAN
1613 code based on older YAZ-versions at compile-time. The fix is easy -
1616 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1617 under the SCAN definition. Remember to initialize this, server-people.
1619 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1620 that this does not extend to ODR and ASN.
1622 Comstack allows insertion of established socket (primarily for
1623 inetd-operation of servers). Doc updated.
1625 Front-end server can now start from the inetd in TCP mode. Doc
1628 --- 1.0pl4 1996/1/24
1632 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1633 the rank and record number.
1635 Adjustments to the frontend server.
1637 Fixed diagnostic BER dumper. It ignored the file argument.
1641 Various changes to retrieval module.
1643 Changed the union discriminators of the protocol files from enums to
1644 ints paired with #defines.
1646 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1649 *Changed operator in the RPN structure to 'roperator', again to avoid a
1652 Fixed problems in Explain decoders/encoders.
1654 --- 1.0pl2 1995/12/6
1656 Memory bug in log module fixed.
1658 --- 1.0pl1 1995/12/5
1660 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1662 Bug in Explain DatabaseInfo module fixed.
1664 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1668 The shift to v1.0 signals that we now consider the *core* functionality
1669 of YAZ reasonably stable (the core being more or less equivalent to
1670 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1671 tested (Explain not at all - though that will happen soonish).
1673 Minor changes to code to support Windows port.
1675 Various minor changes after we're getting to use GRS-1 & co. more.
1677 Added Espec-1 format.
1679 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1680 of the protocol and it cannot be selected when encoding (maps into 'string'
1681 when decoding). Needed to talk to some servers.
1683 Demo client can request simple element set names.
1685 Added Diagnostic Format encoders/decoders.
1687 Added simple Close handling to frontend server (no hooks for resource
1688 reporting yet), and demonstration client.
1690 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1692 --- 1.0b3 1995/08/24
1694 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1695 handled incorrectly when records were requested in the searchResponse. This
1696 will only affect you if you use the frontend-server.
1698 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1699 Test-client will ask for and print GRS1. Ztest will return dummy records
1702 Added Explain encoders/decoders to the service-level API. Untested.
1704 Added Extended Services: Item Order encoders and decoders to the Service-
1705 level API. Untested. We could use a recent copy of the pertinent bits
1706 of the ILL protocol to add those bits.
1708 Added diagnostic format 1 encoders/decoders to the service-level API.
1711 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1712 odr_cons.c, which causes a more correct output.
1714 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1715 was always set to 0 when no records were requested in the searchRequest.
1717 * Added better external-handling. This shouldn't harm old code that
1718 *encodes* externals. It can break code that looks for a
1719 'single-ASN1-type' representation, since those types that are known
1720 are now decoded immediately. Look at the SUTRS sample code in
1721 seshigh.c and client.c. Documentation updated.
1723 Handling of structured records in bend_fetchresponse. Length -1 marks
1724 structured record, type is deduced from format field.
1726 --- 1.0b2 1995/06/27
1727 Fairly quick maintenance release to add SUTRS support.
1729 Fixed handling of SUTRS records in the demonstration client.
1731 * Added format field to the bend_fetchrequest and bend_fetchresponce
1732 structures of the backend API (frontend server). When the record is
1733 returned, the value of the format field is mapped to an OID. The
1734 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1735 of the record. The special value VAL_NONE in the bend_request means
1736 that no specific format was requested by the client. Documentation
1737 updated accordingly. Test server (ztest) will return a fixed dummy
1738 SUTRS record if your client requests SUTRS.
1740 Documentation updated accordingly.
1742 You can now set external libraries and RANLIB support in the top-level
1746 First public release.
