3 Utility yaz_iconv now supports conversion to MARC-8.
5 New facilities for the MARC module. The reading - and writing of
6 content are separate methods for the yaz_marc_t handle. The following
7 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
8 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
9 format). Write functions have prefix yaz_marc_write_.. The existing
10 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
11 available. Removed support for OAI-MARC and simplexml (not the
14 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
15 to be returned for this connection.
19 Allow multiple languages and charsets to be specified with
20 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
21 negcharset iso-8859-1,utf-8
23 Translation of proximity nodes from CQL into PQF now works.
25 Moved to automake 1.8, 1.9.
27 Added function yaz_log_set_handler which allows a log handler to be
28 installed. This handler will be called for all log messages. Output
29 to file is also produced; but that can be disabled by passing NULL
30 fname to yaz_log_init_file.
32 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
34 For SRW (including GFS), accept application/soap+xml as content-type
37 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
38 produces NO stylesheet reference even if a default stylesheet is specified
43 Updated Windows package to include yazd.dll + yazd.lib for the
44 Development component.
46 If the environment variable YAZ_LOG is set, then it is used as a
47 string indicating the default level of logging to use if not
48 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
49 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
50 used as before. So, for example, to omit warnings from YAZ logging,
53 cql_transform() now map structure and other attributes before indexes,
54 so that index-specific structures and other attributes can override
55 defaults. So now a combination of mapping specifications such as:
57 index.dc.date = 1=date-modified 4=5
60 cql_transform() now also respects the "always" mapping specification,
61 which establishes an initial set of attributes to be used for all
62 terms except where overridden by more specific attributes associated
63 with the index, relation or modifier.
65 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
66 which mode to use; one of "post", "get" or "soap" (SRW, default).
68 Fixes for yaz_iconv routines: changed trie-based character set conversions
69 to use only non-negative values for bit fields due to Sun's C compiler not
70 supporting negative values.
72 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
73 sequences where not read correctly. Fix by Rustam Usmanov.
75 Updated win/makefile to use options, settings which makes things
76 compile with VS C 2005.
80 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
82 In ZOOM socket code, use select instead of poll on MacOSX.
84 ZOOM-C now support client-side compilation of CQL into RPN that is
85 sent to the server, enabling CQL to be used against all Z39.50
86 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
87 ZOOM_query object, and submit it using ZOOM_connection_search().
88 The CQL-to-RPN translation uses a configuration file, the name of
89 which must be specified in the Connection's "cqlfile" option.
91 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
92 function, which takes as its start-term parameter a ZOOM_query object
93 (which may have had either CQL or RPN set into it).
98 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
99 GFS to support this as well. Backend handler, bend_srw_update, does the
100 update work. Code contributed by Ko van der Sloot.
102 Allow retrieval of Search Result-1 information in ZOOM by the use of
103 options that are attached to a result set. ZOOM documentation updated
106 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
107 UTF-8 conversion. Patch by Raj Patel.
109 Added option -m to GFS to control formatting of timestamps in log file.
111 Added 'exit' as synonym for 'quit' in yaz-client
113 Added support for specifying SRW resultSetId + resultSetIdleTime in a
114 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
115 for the new members. Patch by Ko van der Sloot.
117 Added support for SRU POST. It is supported for content-type
118 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
120 Do not build the separate Multi-threaded (MT) library libyazthread.la.
121 Instead make the library libyaz.la multi-threaded. Threading as a whole
122 can still be disabled by configure option --disable-threads. Previosly,
123 with older GLIBCs there were problems with MT libs under Apache. This
124 has now been fixed a long time ago.
126 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
129 CQL module modified to be case insensitive for relations/indexes/operations.
131 Fixed bug in CQL transform code: incorrect value relationModifieder
134 Added 'show all' command for yaz-client which retrieves all results
137 Added new yaz-client, xmles, which takes a (private) OID and
138 a document to be sent as an extended service request.
140 Describe new yaz-client commands wait_response and set_auto_wait.
142 Increase TCP/IP listener backlog from 3 (which I am guessing was
143 copied from the SunOS manual entry way back when) so SOMAXCONN, so
144 that the socket will queue as many incoming connections as it's able
145 to handle ongoing connections. In other words, it will never now
146 refuse a connection that it would be able to handle merely because
147 it's not got around to accepting() enough of the pending connections
148 yet. This is the behaviour anyway under Linux, where the listen()
149 argument is ignored; but not under BSD and on systems such as
150 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
151 YAZ-based servers should now be uniform across operating systems in
154 yaz-marcdump uses 64-bit file access on some systems. This is enabled
155 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
156 This allows yaz-marcdump to read large MARC batches (>2 GB).
158 Modified all YAZ source files - except the source which is auto-generated
159 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
162 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
163 corresponding to the existing *_setl() function. These allow option
164 values containing arbitrary valuues.
166 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
167 ZOOM_resultset_sort() in new applications. Its behaviour is identical
168 except that it returns an indicator of whether or not the sort
169 criterion was accepted (0 for OK, -1 for invalid).
173 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
174 MARC output rather than returning "new" buffer.
176 yaz-client warns about unknown init options.
178 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
182 Added support for SRW sort in Generic Frontend Server. Patch
183 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
184 sortKeys - or NULL if none is provided.
186 Fixed bug #307: It was impossible to specify indefinite/no timeout
187 for ZOOM_event. Special timeout value -1 now means indefinite timeout
190 Added support for multiple languages and charsets to be specified in
191 ZOOM. Each charset/language is separated by a blank. If negotiation is
192 in effect in init-response, Option
193 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
194 Code based on patch by Vasiliy Osadchuk.
196 Fixed bug #306: infinite recursion that occurred when calling
197 yaz_log_level_init as the first call (before other log level or
200 Fixed bug in scan handling in front end server: if preferred-Position-In-
201 Response was non-present, a NULL pointer referece was performed.
205 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
206 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
207 now defined for all those error codes. So instead of putting 109 in
208 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
209 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
211 Modified the yaz-marcdump utility to skip garbage bytes between MARC
214 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
216 Program yaz-client now exits and produces an error message if multiple
217 Z39.50 servers are specified on the command line (none or one allowed
220 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
225 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
227 Fixed bug #272: Preserve spacing for CCL terms.
231 Added support for virtual hosts and multiple backend servers for
232 the YAZ frontend server. The configution is XML based and
233 support specificition of CQL to RPN mappings and explain information.
234 See section "Virtual Hosts" in the YAZ manual.
236 Extended OPAC display utility. OPAC display utility renders
237 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
238 to supplement yaz_marc_decode_wrbuf.
240 Fixed a bug in MARC decoder that could caused it to crash for some
241 invalid MARC records. More diagnostics and warnings where added in
242 XML output (warnings, etc are stored in comments).
244 --- 2.0.34 2005/02/08
246 Fixes for UNIX domain sockets. Bug #261.
248 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
250 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
251 Added yaz_marc_subfield_str which defines subfield lead string which is
252 used in YAZ_MARC_LINE format. Default string is blank+$. Added
253 yaz_marc_endline_str which defines end of fields string used in
254 YAZ_MARC_LINE format. Default string is newline.
256 Experimental support for MarcXChange. This format can be produced
257 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
258 http://www.bs.dk/standards/MarcXchange.xsd
260 Added yaz-client commands scansize that sets maximum number of
261 entries to be returned by scan.
263 --- 2.0.32 2005/01/11
265 Added support for SRW scan in yaz-client and Generic Frontend Server.
267 * Added whereInList member to SRW Scan Term.
269 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
271 Fixed NMEM system to return aligned blocks on the smallest boundaries
272 that are suitably aligned for all possible types on the particular
273 architecture YAZ is being built for.
275 --- 2.0.30 2005/01/04
277 Fixed numerious warnings that was issued with newer versions of GCC.
279 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
280 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
283 Make YAZ Generic Frontend Server slightly faster.
285 Enhance (and reduce) logging for Generic Frontend Server.
287 Revert YAZ log system so that it flushes every write operation
288 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
290 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
291 instead of LOG_, due to name clash with syslog(3). LOG_ are still
292 present. New applications should define YAZ_USE_NEW_LOG=1 - this
293 will effectively disable old definitions.
295 --- 2.0.28 2004/11/09
297 Added yaz_log_time_format which specifies log format using
300 Added yaz_log_module_level which returns mask for a module. Value
301 is non-zero mask a if module is enabled; zero if disabled.
303 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
304 in include/yaz/cql.h.
306 Fixed bug #176: Dont throw diagnostics on empty SRU args.
308 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
310 Fixed bug #172: RPM builds does not enable SSL.
312 Doxyfile.in part of dist. Doxyfile generated by configure.
314 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
315 are given and the corresponding component does not exist.
317 Extend CCL documentation in YAZ reference. Describe r=r.
319 --- 2.0.26 2004/10/01
321 Fixed MARC->MARCXML conversion to properly deal with
322 fields, subfields, indicators having non-ASCII characters.
324 Fixed MARC->MARCXML conversion so that ASCII control characters
325 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
328 Added YAZ GFS support for conversion from Z39.50 surrogate
329 diagnostics to SRW surrogate diagnostics.
331 Bug fix: YAZ GFS did not return schema in explainResponse.
333 --- 2.0.25 2004/09/30
335 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
336 now converts recordSchema to elementSetName as well as schema URI.
338 Fixed bug in COMSTACK that prevented HTTP request packages from being
341 --- 2.0.24 2004/09/29
343 Added CCL facility r=r "range" which is similar to r=o "ordered" but
344 does not require white-space before and after the dash in a range, e.g.
345 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
348 Fixed a few AC_TRY_LINK configure tests that did not operate properly
349 due to new GCC removing "redundant" code.
351 Added yaz-client commands scanpos and scanstep that sets preferred
352 position and step-size for scan.
354 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
356 Added CCL utility ccl_qual_buf which parses one or more CCL
357 spec lines in a buffer.
359 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
360 of name and value - ignoring empty lines and comments.
362 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
364 Added odr_get_element_path which returns current element path for an
365 ODR handle. This utility is useful in error handling or user-defined
368 Added ODR_PRINT utility odr_set_stream which is is a more generic
369 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
370 to a write function and pointer to close function. The close function - if
371 non-NULL - will be called during odr_destroy.
373 Fixed bug in CCL parser where truncation char was not removed from
374 right side when truncation=both was in effect.
376 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
379 --- 2.0.23 2004/08/11
381 Fix buffer overrun in CQL parser when dealing with proximity (%).
383 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
384 to UTF-8/UCS conversion is now only based on codetables.xml.
386 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
388 --- 2.0.22 2004/08/06
390 Add support for more "commit changes" in ZOOM (uses Extended Services).
392 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
395 Yet another small fix for configure of SSL.
397 --- 2.0.21 2004/05/14
399 Fix SSL libs for configure when --with-openssl=DIR is given.
401 --- 2.0.20 2004/05/10
403 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
405 SSL comstack now uses yaz.pem certificate file on server side
406 by default. Certificate filename can be configured by calling
407 comstack function cs_set_ssl_certificate_file before cs_bind is used.
409 Fix bug regarding multiple calls to ZOOM_connection_connect.
411 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
413 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
414 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
416 ZOOM now allows inspection of X509 peer certificate for verification.
417 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
419 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
420 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
421 as "modular" but it simplifies things.
423 Added cs_get_peer_certificate to that returns peer X509 PEM.
425 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
426 NULL if SSL is unavailable.
428 Documentation about MARC decoding tools.
430 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
432 --- 2.0.19 2004/03/30
434 Rename CHANGELOG to NEWS to follow GNU style packing.
436 Fix bug with missing initialization of member in init_diagnostics.
437 This bug affects threaded version of GFS server.
439 --- 2.0.18 2004/03/20
441 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
444 Ensure zlib.dll is packed with Windows install.
446 --- 2.0.17 2004/03/17
448 Fix encoding of xsd:string to use text instead of CDATA.
450 Fix endless loop in CQL parser with unbalanced ".
452 Use a more compact way to store MARC-8 conversion tables.
454 --- 2.0.16 2004/03/16 Debian only
456 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
459 Update CQL parser to use new CQL 1.1 modifiers for booleans and
464 --- 2.0.15 2004/03/01
466 Another fix for decoding of XML packed records.
468 --- 2.0.14 2004/02/25
470 Fixes for Chunked encoding. White space not ignored after length spec.
472 Update NS and use default NS for SRW diagnostic elements.
474 --- 2.0.13 2004/02/23
476 Implement ZOOM_resultset_cache_reset which resets record cache.
478 Implement ZOOM_resultset_sort which sorts a result set.
480 Implement chunked HTTP transfer.
482 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
484 --- 2.0.12 2004/02/16
486 Added member 'schema' to bend_explain_rr structure so that backend
487 can specify explain record identifier. Defaults to Zeerex 2.0.
489 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
491 --- 2.0.11 2004/02/16
493 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
496 Added init command for yaz-client which sends "extra" init request.
498 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
499 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
501 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
503 Make ZOOM error code for "invalid query".
505 Fixed compilation for SSL which wasn't properly enabled for all platforms.
507 --- 2.0.10 2004/02/05
509 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
512 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
514 Added option -p <file> to make Generic Frontend Server to write PID file.
516 Added option -D to put Generic Frontend Server in background on its own.
518 Make ZOOM C recognize option "password". If unset, "pass" is used
519 (for backwards compatibility).
521 Fixed a bug in Generic Frontend Server that could make it crash if a
522 client sets characterSetNegotation bit, but didn't pass negotiation stuff
525 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
526 Must be issued before open, in order to be in effect.
528 --- 2.0.9-6 2004/01/12 Debian/Windows
530 Make the SRU server more picky WRT unknown params, etc.
532 Bug fix: ZOOM scan response didn't return displayTerm - when present.
534 New YAZ client command, options, that sets Z39.50 options.
536 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
537 options from a string of tokens (one token for each option bit).
539 Update SRW diagnostic code messages.
541 --- 2.0.9-5 2004/01/07 Debian/Windows
543 Handle user defined stylesheet for SRW/SRU.
545 --- 2.0.9-4 2004/01/06 Debian/Windows
547 Fix bug in decoding of Content-Length.
549 --- 2.0.9-3 2004/01/06 Debian/Windows
551 Fix a bug with decoding of XML packed records.
553 --- 2.0.9-2 2004/01/05 Debian only
555 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
557 Fix bug in SRW/SRU diagnostics decoding.
561 Fixed bug in Generic Frontend Server which could drop records exceeding
562 preferred message size. Reported and fixed by Irina Dijour.
564 Fixed calculation of package size for structured records in Generic
565 Frontend Server. Reported and fixed by Irina Dijour.
567 Fixed namespace for SRW/SRU diagnostics.
569 Fixed SEGV in yaz-client that occured for HTTP connection errors.
573 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
574 this version is incompatible with version 1.0 and older YAZ SRW/SRU
577 CQL changes to reflect recent changes to the specification:
578 * Documentation talks about context sets instead of index sets.
579 * Documentation talks about indexes instead of qualifiers.
580 * The CQL-to-PQF transformer's configuration file now uses
581 "index.set.name = <attributes>" instead of the old form
582 "qualifier.set.name = <attributes>". (Both forms are still
583 understood but the latter is deprecated.)
584 * CQL terms with no explicit index specified are now interpreted as
585 cql.serverChoice instead of srw.serverChoice (which of course
586 behaves exactly the same.)
590 MARC conversion can now generate ISO2709 output in another
591 character set. yaz-marcdump uses this facility if you invoke it
594 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
595 functions from there can be used from C++.
599 Frontend server now transfers memory from decoded packages to stream
602 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
603 references to show up.
605 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
606 the ZOOM Abstract API. The older names for the same options are still
607 also supported for the benefit of old applications.
609 ZOOM-C supports "implementationId" and "implementationVersion" options
610 to go along with "implementationName". These allow the user code to
611 specify identification strings to be sent to servers.
612 Add OID for the new ExtLite attribute set.
614 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
615 as requested/supplid by Ere Maijala <ere@atp.fi>
617 For generic frontend server, reverse the order of
618 "toolkit-supplied / application-supplied" strings sent as implementationId,
619 Name and Version. Also, remove the spaces around the slash. This brings
620 the GFS in line with the behaviour of ZOOM-C on the client side.
622 Add function ZOOM_scanset_display_term.
624 yaz-client shows scan displayTerm if present.
626 Utility yaz-iconv is now installed by default along with the man page
629 Extend configure check for OpenSSL to use pkg-config where available (such
632 Incorporate patch by Morten Bogeskov which allows a Unix file socket
633 server to specify uid/gid/mask for socket using the format
634 unix:[user=uid,][group=gid,][umask=mask,]file=path
635 If file= is omitted the existing format is assumed, e.g.
637 in which case the mask is 0666 (rw for everybody).
639 Major restructure of YAZ source. All source in libyaz is in src directory.
640 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
641 util (utility programs such as ASN.1 compiler, yaz-marcdump).
643 Added man page for utility yaz-marcdump (used to be called marcdump).
644 yaz-marcdump is installed by 'make install'.
646 Fixed a memory leak in Generic Frontend Server that occurred when decoding
647 of incoming package failed.
649 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
651 Change prototype of odr_perror: add const to message string.
653 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
655 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
656 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
657 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
658 DNS lookup. There should not be any compatibility problems with this
659 assuming that blocking=1 or 0 is used.
661 Fix bad reference in UNIX comstack in function cs_addrstr.
663 Fix for compilation on AIX.
665 The generic front-end server (server/seshigh.c) now supports returning
666 Init diagnostics to the client in User-information-field, in
667 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
672 Allow any CQL relation (not just all,any,exact,scr).
674 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
675 that features the same UI.
677 Implemented command update0 in YAZ client which is equivalent to
678 update but uses old of Ext Update ASN.1.
680 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
681 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
682 Previously no OID was used for this info.
684 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
685 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
686 returns 'malformed search term' otherwise.
688 SortResponse member resultCount now set to NULL in sort handler of
691 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
694 Add three new utility functions for translating OIDs between various
695 formats -- symbolic name such as "Usmarc", minus-1-terminated int
696 arrays and dotted strings such as "1.2.840.10003.9.5.1":
697 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
698 char *oid_to_dotstring(const int *oid, char *oidbuf);
699 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
701 Reverted modifications for ES Update definition for z_IU0Update
702 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
703 is back to YAZ 2.0.2.
705 String value attributes for CCL parser.
707 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
708 which their FirstSearch server returns in Init responses, sometimes
709 carrying useful diagnostic information when Init fails. This has the
710 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
711 "z39.50/oclcui.asn", where its definition is somewhat different from
712 what OCLC document on their web-site, as required to interoperate with
715 Support for anonymous authentication in yaz-client. Use the command
718 * Fix the OID of the Index Data-local "admin" Extended Service from
719 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
720 the 1000, which indicates a locally-defined OID, was a mistake.
724 Fix CCL directive @case handling so that it affects string match for
725 both CCL keywords and qualifiers.
727 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
728 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
729 Decoder has been updated with ASN.1 changes as listed in
730 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
731 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
732 z_IUUpdate, remains unchanged.
734 ZOOM_record_get may now return a record in a specific character set.
735 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
736 "from" is the character set of record as returned by target. "to" is
737 the character set to be returned. If omitted, "to" is UTF-8.
739 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
741 New ODR utility, odr_getelement, which returns name of element for
742 which encoding/decoding failed.
744 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
745 in cases where a required element was omitted.
747 Bug fix: some MARC8 sequences were not converted.
749 New ZOOM option "step" which specifies number of records to be
750 retrieved in one chunk. Used in conjunction with "start" and "count".
752 SRW support for yaz-client. Use scheme http: to use it, e.g.
755 yaz-client no longer does (un)intelligent character set conversions
756 by default. Can be enabled with charset and marc_charset commands.
758 xmalloc trace fix for 64-bit systems such as DEC alpha.
760 Solaris 2.6 compile fix.
762 New function, cql_strerror() translates SRW error codes, as returned
763 by cql_transform_error(), into human-readable English strings. Used
764 in yaz-client diagnostics when appropriate.
766 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
767 converts it into a type-1 query which is sent to the server. This
768 makes CQL available for use with all Z-servers, as opposed to the tiny
769 minority that can handle CQL queries themselves.
773 New Debian package layout similar to the Redhat Package layout.
775 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
776 and search result respectively.
780 Redhat package is now several packages: libyaz (runtime libraries),
781 libyaz-devel (development and documentation, and yaz (utility programs).
782 Package spec file by Morten Bøgeskov.
784 New member 'schema' in struct bend_fetch_rr which the name of requested
785 schema (SRW/SRU) for record (or NULL if none was given). The fetch
786 handler MAY set this to reflect the schema of the returned record.
788 New member 'display_term' in struct scan_entry. GFS now sets member entries
789 and allocates scan entries to be filled by user scan handler. In previous
790 version, entries member was allocated by the scan handler. That still works,
791 but the GFS will ignore member display_term - assuming it was NOT set by
792 the handler. The fact that the GFS now allocates the entries both allows
793 for new members and makes a scan handler easier to write.
795 Fix CQL lex buffer overflow.
797 SRW/SRU recordPacking. For SRW default recordPacking is string. For
798 SRU default recordPacking is string.
800 SRU protocol support for frontend server.
802 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
804 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
806 Added scan for the ZOOM shell (zoomsh).
810 * String Identifers for Schemas (Amendment 5).
811 http://lcweb.loc.gov/z3950/agency/amend/am5.html
812 Old definition for schema
813 Odr_oid *schema; /* OPT */
818 Z_InternationalString *uri;
819 #define Z_Schema_oid 1
820 #define Z_Schema_uri 2
823 * resultCount parameter to Sort Response (Amendment 1).
824 http://lcweb.loc.gov/z3950/agency/amend/am1.html
826 Support for SRW 1.0 over HTTP. This is an optional feature and
827 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
830 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
831 on the same port. SRW SearchRetrieveRequests are mapped
832 to bend_init,bend_search,bend_fetch,bend_close.
834 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
836 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
837 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
839 ZOOM connections are SRW based if schem http is used for hostname
840 in connect, e.g. z = ZOOM_connection_new("http://myserver");
841 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
843 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
844 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
845 distance=n, order=true/false, relation=le, prox unit=word. If
846 n is omitted, distance 1 is used.
848 Fixed problem with C compiler include path in wrong order.
850 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
851 on Solaris. Patch from Ko van der Sloot.
853 New MARC decode API. All new functions operate on a yaz_marc_t
854 handle. The most important new functions are: yaz_marc_create,
855 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
856 decode and destroy respectively. Decoder can produce formats
857 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
858 include/yaz/marcdisp.h.
860 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
861 to UTF-8, UCS-32, wchar_t or Latin-1.
863 * Prototypes for yaz_iconv_-functions moved to separate header
864 include/yaz/yaz-iconv.h.
866 Make a few private functions 'static' in unix.c. This prevents
867 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
869 For ZOOM connection, the options targetImplementation{Id,Name,Version}
870 are set when Init Response is received.
872 New function ZOOM_connection_error_x similar to ZOOM_connection_error
873 but returns diagnostic set as well.
875 New function yaz_strerror which is a portable wrapper for
876 strerror/strerror_r/GetLastMessage.
878 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
879 is returned for MARC. If type is "oai", then OAI MARC is returned.
881 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
886 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
888 Fix bad race conditions on SIGTERM and terminate gracefully in
891 Move retrieval (data1) module to Zebra since nobody seems to be
894 Add GRS-1 render for ZOOM using same format as yaz-client.
898 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
900 Fix broken ESpec handling in data1 module.
902 SGML reader parses comments and makes them part of the data1 tree.
904 Added several type casts so that YAZ compiles as C++ code.
906 ZOOM didn't handle PDU encoding failures properly.
908 Added more Bib-1 diagnostics (approved extensions).
910 GNU configure: better check for iconv.
912 More portable use of accept, getpeername. Check for socklen_t. Use
913 int/size_t if socklen_t is not defined.
917 PQF parser rejects bad queries - including those with extra
918 characters in them. PQF parser used to silently ignore that.
919 Cleaner API for PQF added, which allows you to get detailed
920 error information for bad queries (see yaz/pquery.h).
922 Fixed bug in ZOOM_record_get for type "database".
924 Implemented mini iconv library supporting conversions between
925 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
927 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
931 Fixed ZOOM C record cache so that preferredRecordSyntax and
932 elementSetName is used to check for already fetched records.
936 Added three members in bend_initrequest structure to facilitate
937 character set negotiation.
939 Fixed a bug in frontend server that could cause indefinite
940 loops under rare conditions.
942 Revised character set utilities (charneg.h) so that encoding
943 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
945 For PQF, directive @term <type> sets term type for Scan/Search.
946 Here <type> is general, string, numeric, null. The term type
947 is inherited - just like @attr.
949 New call odr_set_charset that sets character set conversion for
950 international-strings on a ODR stream. Prototype is:
951 int odr_set_charset(ODR o, const char *to, const char *from);
952 The InternationalString is still represented as C string in YAZ
953 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
954 won't). On the protocol level, you can use any encoding.
956 Support for UNIX sockets in ZOOM.
958 Solaris recv sometimes returns errno == ENOENT. It is treated as
959 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
961 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
962 both client and server. Code by Morten Bøgeskov.
966 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
967 that they can be used directly from Visual Basic. You must recompile
968 your windows APP if you're using ZOOM.
970 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
971 Commands "lang" and "charset" sets language and character set respectively.
972 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
973 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
975 Attributes from multiple CCL fields may be OR'ed rather than merged
976 using directive "@field or". Fields are still merged by default -
977 equivalent to "@field merge".
979 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
982 Fixed bug in zget for parameter ExtendedServicesResponse.
988 Added PQF feature: '@attr type=value' may be written as '@type=value'.
990 Client displays USR.1:SearchResult-1 (hits per term).
992 Additional Search Info for search in Generic Frontend Server.
994 Fixed CCL parsing of "field=s".
996 WIN32 installer - using the excellent NSIS software from nullsoft.
998 Fixed CCL parsing of "field = - <number>".
1000 Added function yaz_marc_decode that decodes MARC for line mode
1001 display or XML (similar to that used by JZKit).
1003 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1004 Z39.50. But ISO/ILL was, however.
1006 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1007 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1009 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1010 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1012 --- 1.8.5 2002/02/03
1014 New YAZ client features: Command completion and new commands:
1015 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1016 Code provided by Jacob Poulsen.
1018 New call oid_trav, that visits all registered OIDs via callback.
1020 Function ZOOM_record_get now returns const char pointer rather than
1021 void pointer. It saves a lot of type casts.
1023 For YAZ client, command "auth" now allows you to set authentication
1024 in IdPass style. It is enabled when three tokens are given - order
1025 is user, group and password.
1027 Fix memory leaks in MARC record handling for ZOOM.
1029 New option for YAZ client, -k <kilobytes> that sets
1030 maximum record size. Similar to -k option for generic frontend
1031 server and yaz-ztest.
1033 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1035 Prefix query parser reports "fail" when bad attribute set is given.
1037 Fix in MARC decoder. Proximity logging. Fix for attribute set
1038 in scan handler for server. Patches by Shigeru Ishida.
1040 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1043 Configure option --with-openssl=<dir> now works when a directory is
1044 specified. Patch provided by Morten Bøgeskov.
1046 New option for YAZ client, -u <auth>, that sets authentication.
1048 ZOOM fix: error information was sometimes "missing", since error
1049 was cleared/reset too when it shouldn't.
1051 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1053 --- 1.8.4 2002/01/04
1055 Scan for ZOOM API. New object ZOOM_scanset. New functions
1056 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1057 ZOOM_scanset_destroy.
1059 New ZOOM function, ZOOM_connection_last_event, that returns type
1060 of last event (such as "receive data", "send data", "apdu received",
1063 New ZOOM option, schema, that specifies schema for retrieval.
1065 New CCL feature. Qualifiers can be aliases for one or more
1066 other qualifiers (if more than one is given, OR is used).
1068 ZOOM uses named result sets if target supports it.
1070 Two new YAZ client commands: . (dot, which sources a script of YAZ
1071 client commands), and ! (to execute shell command.). Implemented
1074 Working on Debian packages.
1076 --- 1.8.3 2001/11/19
1078 YAZ client enables named result sets only if target supports it.
1080 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1082 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1083 with key="host" to get same result.
1085 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1086 Function Z3950_resultset_record(s) returns references to records
1087 "owned" by resultset. To become owner use Z3950_record_clone.
1089 Function z_ext_record handles Extended Services. Thanks to
1092 --- 1.8.2 2001/11/12
1094 CCL Parser fix: ignore token comma when dealing with and-lists.
1096 Documentation updates for COMSTACK.
1098 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1099 Changed prototype Z3950_records. For some functions, int parameters
1100 were changed to size_t.
1102 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1105 New MARC decode/display function, marc_display_exl, which properly rejects
1106 non-ISO2709 records. YAZ client uses it.
1108 --- 1.8.1 2001/10/29
1110 Fix bug: local attribute set wasn't set correctly in PQF strings.
1114 * Old Z39.50 codecs no longer supported.
1116 Added ZOOM C binding. See http://zoom.z3950.org/
1118 Renamed states for COMSTACKs to avoid confusion with events.
1120 Implemented cs_look and proper cs_rcvconnect.
1122 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1124 Configure detects POSIX threads on OpenBSD.
1126 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1127 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1129 When error is returned from present handler, non-surrogate diagnostic
1130 is returned in present response (and fetch handler is no longer called).
1132 * Minor adjustments to pquery parser (PQF). Token characters may be
1133 escaped by using backslash (C-style).
1135 PQF parser allows string attribute values to be specified. For @attr,
1136 non-numeric characters after the equal-sign are treated as strings
1137 (e.g. @attr 9=title).
1139 CCL trunction character may be defined (@truncation in file)
1141 * function zget_ExtendedServicesRequest sets waitAction to
1142 waitIfPossible (was wait).
1144 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1147 CCL operator names may be set in field definition files (CCL_bibset).
1148 See ccl/bib1 for an example.
1150 Fixes in ASN.1 compiler for C++ compatibility.
1152 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1153 and "op_or" to avoid conflict with C++.
1155 Fixed problem with GNU readline detection on Redhat 7.0.
1157 Added step-size for Scan backend handler.
1159 Fixed bug that made the frontend server crash when no attribute
1160 set was specified for scan.
1162 Front-end server automatically switches to original working directory
1163 when installed as an NT service. Previously -w had to be specified to
1166 Added extended attributes for retrieval module (data1), so that data1
1167 records carry d1_readXML/SGML attributes. d1_read also supports
1168 null-data rules ( <tag/>)
1170 On UNIX when POSIX threads are available, a separate library libyazthread
1171 is created. Programmers should link with that library and the yaz library
1172 when using threads. The reason for the split was that some applications
1173 on Linux, such as Apache, doesn't work well when using shared objects that
1176 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1177 (or any frontend server) in SSL mode by specifying ssl: followed by
1178 address. Only tested on UNIX.
1180 Added feature for CCL module. Virtual structure s=al or s=ol generates
1181 and-list and or-list respectively instead of phrase search.
1185 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1186 log_mask_str. This was done to avoid name conflicts with other libraries
1187 (such as other PHP extensions).
1189 Added raw OID member for preferred record syntax (request_format_raw)
1190 and returned record syntax (output_format_raw) for backend fetch method.
1192 Config file yaz-config now accepts options so that it returns specific
1193 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1195 Shared library support for UNIX using GNU libtool.
1197 * Modified backend interface. Request/Response struct's replaced by
1198 one read/write C struct. For example bend_fetchrequest and
1199 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1200 Every handler - even search has to be registered in bend_init
1201 handler. This means that the YAZ library no longer refers to
1202 external functions and it makes it possible to make the whole
1203 thing a single DLL/SO.
1205 Added Segment handler for backend server.
1207 Added Zmbol/Zebra administrative functions to YAZ client.
1209 Threaded frontend server on UNIX (when POSIX Threads are available).
1210 Starting the server with option -T enables multi-threading.
1214 Added configure option --enable-comp/disable-comp to control use
1215 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1216 located in sub directory asn.
1218 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1219 in ${exec_prefix}/bin along with the other programs yaz-client and
1222 GNU automake used to maintain makefiles.
1224 Added several OID's.
1226 Changed retrieval module so that we can load records with no abstract
1227 syntax defined. Tagpaths in these records are fully composed of string
1230 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1234 On UNIX, the generated makefile now supports a proper 'make install'.
1235 The prefix can be set via GNU configure to set the install location
1236 (default is /usr/local).
1238 * YAZ programs client and ztest were renamed to yaz-client and
1239 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1240 locations, such as /usr/bin,/usr/local/bin,etc.
1242 * YAZ Header files were moved from include to include/yaz. YAZ Header
1243 files are referred to as include <yaz/log.h> rather than <log.h>.
1244 The YAZ include path (-I ..) is therefore the same as before. Programmers
1245 should update their #include statements or use -Ipath/include/yaz
1246 instead. The main motivation for doing this change is that YAZ header files
1247 can be installed in "standard" locations /usr/include,/usr/local/include
1248 without introducing conflicts, since ALL YAZ header files are stored
1249 in subdirectory yaz (under /usr/include for example).
1251 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1252 rather than project/workspace files. We switched because project files
1253 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1256 Changed name of logging function, logf, to yaz_log, to prevent name
1257 clash with some math-log functions. The YAZ header log.h defines logf
1258 to yaz_log (#define) so there should be no incompatibilities by this
1261 Added bend_start/bend_stop handlers for server. These handler are
1262 called on start/stop of server. For windows they are called whenever
1263 a service is started/stopped.
1265 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1266 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1267 in util/yc.tcl. The auto-generated C code structures are, in a few
1268 cases, incompatible with the old decoders. There are differences in the
1269 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1270 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1271 The preprocessor variable ASN_COMPILED is defined when the compiled
1272 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1273 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1274 wish to use the old encoders/decoders you can specify --disable-yc
1277 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1278 version so that it supports both new - and old version of DB Update
1280 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1281 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1282 change. The name parameter can be set to 0 in which no name is specified
1283 for the construction. The macros odr_implicit and odr_explicit sets name
1284 parameter to zero for the construction involved. New macros
1285 odr_implicit_tag and odr_explicit_tag are similar to the others,
1286 except that a name parameter is added. For programmers' that don't use
1287 ODR they probably only need to change the call to z_APDU and z_External.
1289 Added access control facility by interfacing the TCP wrapper library.
1290 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1291 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1292 name of the daemon and enables the access control as specified in
1293 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1295 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1296 den Dool <H.M.vdnDool@kub.nl>.
1298 Added reference ID parameter to most functions in server API - refer
1299 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1301 Changed name of ccl library to libccl.a (was ccl.a).
1303 Fixed bug in decoder for Explain (Category TargetInfo).
1305 Added support for GNU readline in client. Thanks to Jacob Poulsen
1306 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1308 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1309 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1310 IMPLEMENTATION! This change was made to the development version before
1311 the ZIG decided to retract the amendment. If any users MUST be
1312 compatible with the original Update definition, PLEASE CONTACT US, and
1313 we will include a separate definition corresponding to the old Update
1314 ES. Note that because of the change to the ASN.1 of the
1315 TaskPackageRecordStructure we cannot define a single structure that
1316 will support both versions.
1318 * Added const modifier to buffer parameter for some ODR/BER encoding
1319 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1320 completeWAIS, odr_dumpBER.
1322 Fixed bug in client.c which caused a crash when a scanResponse didn't
1323 contain positionOfTerm.
1325 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1326 * will cause an error in a client if a non-YAZ target sends both a
1327 * list of Scan entries and non-surrogate diagnostics.
1329 Retrieval module enhancements. Tag sets may be typed in the reference
1330 to it. From the .abs-file the "tagset" directive takes a third optional
1331 integer type for the tag set referenced. From a .tag-file the "include"
1332 directive takes a third optional type as well. The old "type" directive
1333 in the tag set itself is still recognized but acts as the default type
1336 Backend interface change. Individual Scan terms returned from bend_scan
1337 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1338 in include/backend.h.
1340 Retrieval module enhancements. Multiple tag sets and attribute sets may
1341 be specified in abstract syntax specs. Revised the error/warning for
1342 logging messages reported by the retrieval module when reading the
1345 Object Identifier system (oid_..) changed. The API is backwards
1346 compatible but the oid-routines now allocates new OID's when needed.
1347 Raw OID's may be specified in oid_getvalbyname.
1349 YAZ now uses GNU configure to generate Makefile(s).
1351 * Minor changes in some of the member names of DeleteResultSetRequest and
1352 DeleteResultSetResponse. See include/proto.h.
1354 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1355 and added member 'languages' in TargetInfo (which was missing).
1357 Changed the way attribute sets are handled in the retrieval
1358 module. These are now cached, just like the abstract syntaxes
1361 Changed YAZ so that it links with compiled ASN.1.
1363 Added Explain-schema definitions and mapping routines. The following
1364 Explain categories have been implemented: AttributeDetails,
1365 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1367 Fixed minor bug in Windows version of Server Library.
1369 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1371 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1373 Added EXTERNAL: UNIverse Resource Report (non-standard).
1375 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1376 ENUMERATED and SET OF.
1378 * Added 'const' to some of the char pointer arguments for the
1379 functions, data1_read_node, data1_getelementbytagname,
1380 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1383 Fixed bug in data1_insert_taggeddata - the last_child member of
1384 parent wasn't initialised.
1386 * Changed data1_read_record and data1_read_node so that the supplied
1387 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1388 doesn't refer to any parts of the "SGML"-buffer.
1390 Fixed bug in server library (Windows version of statserv_remove).
1392 * Changed code so that it compiles as C++. The type definition
1393 of Odr_fun which is a member of Odr_arm was changed. The result is,
1394 that an explicit typecast is needed for the fun pointer when
1395 using Odr_arm - as in:
1396 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1398 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1400 Implemented the new structured date and time definition as approved
1401 by the ZIG. Added schemaId element to the specificTag in Espec-1
1402 (also approved at the last ZIG). Thanks to RVDM.
1404 Added some Object identifiers (RVDM).
1406 Changed the Update Extended Service (RVDM).
1408 Added command "refid" to client which specifies referenceId for
1409 the following requests.
1411 Implemented extended service handling for server. See ztest.c
1412 for an example as well as backend.h. New handlers are registerd
1413 in the Init handler.
1415 * Changed interface for sort in server.
1417 Added new members to statserv_options_block. It allows a server
1418 to read options from another source than just the command line. Thanks
1419 to Charles Woodfield.
1421 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1422 renamed to zboolean. Some C++ compilers complained about the name.
1424 Minor changes to gils.abs. Added index 's' (sort) on title
1425 and date/time-last-modified.
1427 --- 1.4pl2 1998/1/30
1429 Fixed bug in server library regarding inetd mode (-i). This bug
1430 was introduced by release 1.4.
1432 --- 1.4pl1 1998/1/29
1434 Added sort facility in client and backend server interface.
1436 Fixed problem with dependencies in Makefile(s).
1438 Fixed bugs for encoders/decoders of extended services and
1441 Implemented sub-tree feature for schemas. Sub-trees are
1442 referenced in *.abs-files. See explain.abs for an example
1443 of the use of this feature.
1445 Modified bib1.att; local attributes for ANY didn't include
1446 ANY itself (only affects use of the retrieval module).
1448 Fixed bug in plain SGML reader in function data1_read_node:
1449 tags with prefix "var" was incorrectly interpreted as variants.
1451 Added feature "sub-schemas" to enable references to - and definitions
1452 of - group of elements.
1454 * Removed member parent from type data1_element (in data1.h).
1456 Implemented function odr_nullval() that returns the value of
1459 * Removed member num_children from data1_node (in data1.h).
1461 Made NT service interface part of the server library. The
1462 function statserv_main uses the NT service when required and
1463 calls the statserv_start / statserv_close routines.
1465 Routine zget_SearchRequest and zget_PresentRequest fills
1466 resultSetName/Id member with "default" instead of "Default".
1468 Fixed memory leak in server. Request queue member wasn't freed.
1470 Fixed nmem_exit so that memory is freed.
1474 Revised the CCL parser utility to be thread safe.
1476 Added function, oid_ent_to_oid, to replace the function
1477 oid_getoidbyent, which is not thread safe.
1479 * Added nmem_init and nmem_exit to initialize and release
1480 NMEM resources. Function nmem_init should be called once in the
1481 initial thread before NMEM/ODR is used. statserv.c and client.c
1482 have been changed accordingly. The change was necessary to make
1483 NMEM thread safe. The NMEM memory pool is shared amongst threads
1484 in a process. Unix-based applications will still work fine without
1487 Added NT Services interface for the the Z39.50 (statserv) Server.
1488 Refer to the ztest.c source on the usage.
1490 Windows 95/NT port using MSVC5.0. Project files are included in the
1493 * Defined new 'global' handle for the retrieval (data1) system. The
1494 new handled, data1_handle, describes the state of the data1 system.
1495 This handle is passed as first argument to virtually all
1496 data1 related routines. The functions data1_create and data1_destroy
1497 creates and destroys a data1 handle respectively.
1499 Added ODR encode stream member to all backend request structures
1500 init, search, scan etc. This stream should be used to allocate all
1501 memory used for the response when thread safe operation is needed.
1503 Changed the comstack utility, cs_addstr, to be thread safe. The
1504 returned hostname string returned by the function is now part the
1507 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1508 function. The cs_straddr takes a COMSTACK handle as argument, so this
1509 function must be used after cs_create and before bind/connect.
1510 This function is thread safe.
1512 Moved test server to 'ztest' directory - generic server code still
1513 in 'server' directory.
1515 Made prefix query (pquery.c) utility thread safe.
1517 Added new function modifier YAZ_EXPORT to 'export' public DLL
1518 functions when using windows (see include/yconfig.h).
1520 Added definitions to the OID database (util/oid.c) (RVDM).
1522 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1524 Added call to ccl_rpn_delete in client program.
1526 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1527 release of RPN structure.
1529 Added support for C++, headers uses extern "C" for public definitions.
1530 With input from RVDM.
1532 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1533 Thanks to Ronald van der Meer (RVDM).
1535 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1537 Added support for private extensions to the OID database
1538 (oid_setprivateoids()). Thanks to RVDM.
1540 Added optional, physical ANY (key replication)
1542 Fixed null-reference problem in GRS-1 output filter.
1544 Proximity operator added to Prefix Query Format (PQF).
1546 In test client command "base" accepts multiple databases.
1548 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1552 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1554 Smallish bug-fixes in the new encoders/decoders (explain).
1556 Bug fixed in DeleteRequest.
1558 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1560 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1562 Added SOIF syntax (using private OID for now) to retrieval module and client.
1564 Added Update extended service.
1566 Added SearchResult-1 additional info structure.
1568 Added optional CCL (ISO8777) interpreter as separate module. Available
1571 --- 1.2 1996/6/10 (1st anniversary release)
1573 Added Summary record syntax. Lightly tested.
1575 Added OPAC record syntax. Untested.
1577 Added ResourceReport service encoders/decoders. Untested.
1579 Fixed bug in z_Unit - wrong tagging on unitSystem.
1581 Fixed bug in the DiagRecs decoder.
1583 Added options for max PDU size and session timeout to frontend-server.
1585 Added documentation of query-language parsers and other supporting utilities.
1587 [frontend-server] Added Attribute set to the bend_scanrequest API.
1589 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1590 surrogate diagnostics were generated.
1592 [retrieval] Allow multiple local values for attribute.
1594 [retrieval] Allow multiple attributes per element in .abs files. index type.
1596 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1598 --- 1.1pl2 1996/4/10
1600 Minor changes, mostly specific to Zebra's requirements (retrieval)
1604 Repaired bug in frontend server when running multiple listening
1605 endpoints in dynamic mode.
1607 z_External() now won't break if a known, ASN.1 value comes encapsulated
1608 in an octet-string. The value will pass through unmodified in an Odr_oct.
1610 Added a bit of code to the demo client to decode & display
1611 ASN.1-structured records represented in the octet-aligned branch of
1612 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1614 Added z_ext_getentbyref() to the ASN module. Doc updated.
1616 * Completed the SCAN definition in the ASN module. This may break SCAN
1617 code based on older YAZ-versions at compile-time. The fix is easy -
1620 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1621 under the SCAN definition. Remember to initialize this, server-people.
1623 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1624 that this does not extend to ODR and ASN.
1626 Comstack allows insertion of established socket (primarily for
1627 inetd-operation of servers). Doc updated.
1629 Front-end server can now start from the inetd in TCP mode. Doc
1632 --- 1.0pl4 1996/1/24
1636 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1637 the rank and record number.
1639 Adjustments to the frontend server.
1641 Fixed diagnostic BER dumper. It ignored the file argument.
1645 Various changes to retrieval module.
1647 Changed the union discriminators of the protocol files from enums to
1648 ints paired with #defines.
1650 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1653 *Changed operator in the RPN structure to 'roperator', again to avoid a
1656 Fixed problems in Explain decoders/encoders.
1658 --- 1.0pl2 1995/12/6
1660 Memory bug in log module fixed.
1662 --- 1.0pl1 1995/12/5
1664 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1666 Bug in Explain DatabaseInfo module fixed.
1668 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1672 The shift to v1.0 signals that we now consider the *core* functionality
1673 of YAZ reasonably stable (the core being more or less equivalent to
1674 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1675 tested (Explain not at all - though that will happen soonish).
1677 Minor changes to code to support Windows port.
1679 Various minor changes after we're getting to use GRS-1 & co. more.
1681 Added Espec-1 format.
1683 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1684 of the protocol and it cannot be selected when encoding (maps into 'string'
1685 when decoding). Needed to talk to some servers.
1687 Demo client can request simple element set names.
1689 Added Diagnostic Format encoders/decoders.
1691 Added simple Close handling to frontend server (no hooks for resource
1692 reporting yet), and demonstration client.
1694 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1696 --- 1.0b3 1995/08/24
1698 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1699 handled incorrectly when records were requested in the searchResponse. This
1700 will only affect you if you use the frontend-server.
1702 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1703 Test-client will ask for and print GRS1. Ztest will return dummy records
1706 Added Explain encoders/decoders to the service-level API. Untested.
1708 Added Extended Services: Item Order encoders and decoders to the Service-
1709 level API. Untested. We could use a recent copy of the pertinent bits
1710 of the ILL protocol to add those bits.
1712 Added diagnostic format 1 encoders/decoders to the service-level API.
1715 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1716 odr_cons.c, which causes a more correct output.
1718 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1719 was always set to 0 when no records were requested in the searchRequest.
1721 * Added better external-handling. This shouldn't harm old code that
1722 *encodes* externals. It can break code that looks for a
1723 'single-ASN1-type' representation, since those types that are known
1724 are now decoded immediately. Look at the SUTRS sample code in
1725 seshigh.c and client.c. Documentation updated.
1727 Handling of structured records in bend_fetchresponse. Length -1 marks
1728 structured record, type is deduced from format field.
1730 --- 1.0b2 1995/06/27
1731 Fairly quick maintenance release to add SUTRS support.
1733 Fixed handling of SUTRS records in the demonstration client.
1735 * Added format field to the bend_fetchrequest and bend_fetchresponce
1736 structures of the backend API (frontend server). When the record is
1737 returned, the value of the format field is mapped to an OID. The
1738 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1739 of the record. The special value VAL_NONE in the bend_request means
1740 that no specific format was requested by the client. Documentation
1741 updated accordingly. Test server (ztest) will return a fixed dummy
1742 SUTRS record if your client requests SUTRS.
1744 Documentation updated accordingly.
1746 You can now set external libraries and RANLIB support in the top-level
1750 First public release.
