1 Allow retrieval of Search Result-1 information in ZOOM by the
2 use of options that are attached to a result set. ZOOM documentation
5 Fixed bug #416: First/second comb characters not handled in the
6 MARC-8 to UTF-8 conversion. Patch by Raj Patel.
8 Added option -m to GFS to control formatting of timestamps in log file.
10 Added 'exit' as synonym for 'quit' in yaz-client
12 Added support for specifying SRW resultSetId + resultSetIdleTime in a
13 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
14 for the new members. Patch by Ko van der Sloot.
16 Added support for SRU POST. It is supported for content-type
17 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
19 Do not build the separate Multi-threaded (MT) library libyazthread.la.
20 Instead make the library libyaz.la multi-threaded. Threading as a whole
21 can still be disabled by configure option --disable-threads. Previosly,
22 with older GLIBCs there were problems with MT libs under Apache. This
23 has now been fixed a long time ago.
25 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
28 CQL module modified to be case insensitive for relations/indexes/operations.
30 Fixed bug in CQL transform code: incorrect value relationModifieder
33 Added 'show all' command for yaz-client which retrieves all results
36 Added new yaz-client, xmles, which takes a (private) OID and
37 a document to be sent as an extended service request.
39 Describe new yaz-client commands wait_response and set_auto_wait.
41 Increase TCP/IP listener backlog from 3 (which I am guessing was
42 copied from the SunOS manual entry way back when) so SOMAXCONN, so
43 that the socket will queue as many incoming connections as it's able
44 to handle ongoing connections. In other words, it will never now
45 refuse a connection that it would be able to handle merely because
46 it's not got around to accepting() enough of the pending connections
47 yet. This is the behaviour anyway under Linux, where the listen()
48 argument is ignored; but not under BSD and on systems such as
49 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
50 YAZ-based servers should now be uniform across operating systems in
53 yaz-marcdump uses 64-bit file access on some systems. This is enabled
54 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
55 This allows yaz-marcdump to read large MARC batches (>2 GB).
57 Modified all YAZ source files - except the source which is auto-generated
58 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
63 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
64 MARC output rather than returning "new" buffer.
66 yaz-client warns about unknown init options.
68 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
72 Added support for SRW sort in Generic Frontend Server. Patch
73 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
74 sortKeys - or NULL if none is provided.
76 Fixed bug #307: It was impossible to specify indefinite/no timeout
77 for ZOOM_event. Special timeout value -1 now means indefinite timeout
80 Added support for multiple languages and charsets to be specified in
81 ZOOM. Each charset/language is separated by a blank. If negotiation is
82 in effect in init-response, Option
83 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
84 Code based on patch by Vasiliy Osadchuk.
86 Fixed bug #306: infinite recursion that occurred when calling
87 yaz_log_level_init as the first call (before other log level or
90 Fixed bug in scan handling in front end server: if preferred-Position-In-
91 Response was non-present, a NULL pointer referece was performed.
95 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
96 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
97 now defined for all those error codes. So instead of putting 109 in
98 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
99 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
101 Modified the yaz-marcdump utility to skip garbage bytes between MARC
104 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
106 Program yaz-client now exits and produces an error message if multiple
107 Z39.50 servers are specified on the command line (none or one allowed
110 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
115 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
117 Fixed bug #272: Preserve spacing for CCL terms.
121 Added support for virtual hosts and multiple backend servers for
122 the YAZ frontend server. The configution is XML based and
123 support specificition of CQL to RPN mappings and explain information.
124 See section "Virtual Hosts" in the YAZ manual.
126 Extended OPAC display utility. OPAC display utility renders
127 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
128 to supplement yaz_marc_decode_wrbuf.
130 Fixed a bug in MARC decoder that could caused it to crash for some
131 invalid MARC records. More diagnostics and warnings where added in
132 XML output (warnings, etc are stored in comments).
134 --- 2.0.34 2005/02/08
136 Fixes for UNIX domain sockets. Bug #261.
138 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
140 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
141 Added yaz_marc_subfield_str which defines subfield lead string which is
142 used in YAZ_MARC_LINE format. Default string is blank+$. Added
143 yaz_marc_endline_str which defines end of fields string used in
144 YAZ_MARC_LINE format. Default string is newline.
146 Experimental support for MarcXChange. This format can be produced
147 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
148 http://www.bs.dk/standards/MarcXchange.xsd
150 Added yaz-client commands scansize that sets maximum number of
151 entries to be returned by scan.
153 --- 2.0.32 2005/01/11
155 Added support for SRW scan in yaz-client and Generic Frontend Server.
157 * Added whereInList member to SRW Scan Term.
159 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
161 Fixed NMEM system to return aligned blocks on the smallest boundaries
162 that are suitably aligned for all possible types on the particular
163 architecture YAZ is being built for.
165 --- 2.0.30 2005/01/04
167 Fixed numerious warnings that was issued with newer versions of GCC.
169 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
170 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
173 Make YAZ Generic Frontend Server slightly faster.
175 Enhance (and reduce) logging for Generic Frontend Server.
177 Revert YAZ log system so that it flushes every write operation
178 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
180 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
181 instead of LOG_, due to name clash with syslog(3). LOG_ are still
182 present. New applications should define YAZ_USE_NEW_LOG=1 - this
183 will effectively disable old definitions.
185 --- 2.0.28 2004/11/09
187 Added yaz_log_time_format which specifies log format using
190 Added yaz_log_module_level which returns mask for a module. Value
191 is non-zero mask a if module is enabled; zero if disabled.
193 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
194 in include/yaz/cql.h.
196 Fixed bug #176: Dont throw diagnostics on empty SRU args.
198 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
200 Fixed bug #172: RPM builds does not enable SSL.
202 Doxyfile.in part of dist. Doxyfile generated by configure.
204 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
205 are given and the corresponding component does not exist.
207 Extend CCL documentation in YAZ reference. Describe r=r.
209 --- 2.0.26 2004/10/01
211 Fixed MARC->MARCXML conversion to properly deal with
212 fields, subfields, indicators having non-ASCII characters.
214 Fixed MARC->MARCXML conversion so that ASCII control characters
215 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
218 Added YAZ GFS support for conversion from Z39.50 surrogate
219 diagnostics to SRW surrogate diagnostics.
221 Bug fix: YAZ GFS did not return schema in explainResponse.
223 --- 2.0.25 2004/09/30
225 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
226 now converts recordSchema to elementSetName as well as schema URI.
228 Fixed bug in COMSTACK that prevented HTTP request packages from being
231 --- 2.0.24 2004/09/29
233 Added CCL facility r=r "range" which is similar to r=o "ordered" but
234 does not require white-space before and after the dash in a range, e.g.
235 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
238 Fixed a few AC_TRY_LINK configure tests that did not operate properly
239 due to new GCC removing "redundant" code.
241 Added yaz-client commands scanpos and scanstep that sets preferred
242 position and step-size for scan.
244 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
246 Added CCL utility ccl_qual_buf which parses one or more CCL
247 spec lines in a buffer.
249 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
250 of name and value - ignoring empty lines and comments.
252 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
254 Added odr_get_element_path which returns current element path for an
255 ODR handle. This utility is useful in error handling or user-defined
258 Added ODR_PRINT utility odr_set_stream which is is a more generic
259 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
260 to a write function and pointer to close function. The close function - if
261 non-NULL - will be called during odr_destroy.
263 Fixed bug in CCL parser where truncation char was not removed from
264 right side when truncation=both was in effect.
266 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
269 --- 2.0.23 2004/08/11
271 Fix buffer overrun in CQL parser when dealing with proximity (%).
273 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
274 to UTF-8/UCS conversion is now only based on codetables.xml.
276 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
278 --- 2.0.22 2004/08/06
280 Add support for more "commit changes" in ZOOM (uses Extended Services).
282 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
285 Yet another small fix for configure of SSL.
287 --- 2.0.21 2004/05/14
289 Fix SSL libs for configure when --with-openssl=DIR is given.
291 --- 2.0.20 2004/05/10
293 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
295 SSL comstack now uses yaz.pem certificate file on server side
296 by default. Certificate filename can be configured by calling
297 comstack function cs_set_ssl_certificate_file before cs_bind is used.
299 Fix bug regarding multiple calls to ZOOM_connection_connect.
301 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
303 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
304 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
306 ZOOM now allows inspection of X509 peer certificate for verification.
307 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
309 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
310 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
311 as "modular" but it simplifies things.
313 Added cs_get_peer_certificate to that returns peer X509 PEM.
315 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
316 NULL if SSL is unavailable.
318 Documentation about MARC decoding tools.
320 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
322 --- 2.0.19 2004/03/30
324 Rename CHANGELOG to NEWS to follow GNU style packing.
326 Fix bug with missing initialization of member in init_diagnostics.
327 This bug affects threaded version of GFS server.
329 --- 2.0.18 2004/03/20
331 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
334 Ensure zlib.dll is packed with Windows install.
336 --- 2.0.17 2004/03/17
338 Fix encoding of xsd:string to use text instead of CDATA.
340 Fix endless loop in CQL parser with unbalanced ".
342 Use a more compact way to store MARC-8 conversion tables.
344 --- 2.0.16 2004/03/16 Debian only
346 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
349 Update CQL parser to use new CQL 1.1 modifiers for booleans and
354 --- 2.0.15 2004/03/01
356 Another fix for decoding of XML packed records.
358 --- 2.0.14 2004/02/25
360 Fixes for Chunked encoding. White space not ignored after length spec.
362 Update NS and use default NS for SRW diagnostic elements.
364 --- 2.0.13 2004/02/23
366 Implement ZOOM_resultset_cache_reset which resets record cache.
368 Implement ZOOM_resultset_sort which sorts a result set.
370 Implement chunked HTTP transfer.
372 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
374 --- 2.0.12 2004/02/16
376 Added member 'schema' to bend_explain_rr structure so that backend
377 can specify explain record identifier. Defaults to Zeerex 2.0.
379 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
381 --- 2.0.11 2004/02/16
383 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
386 Added init command for yaz-client which sends "extra" init request.
388 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
389 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
391 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
393 Make ZOOM error code for "invalid query".
395 Fixed compilation for SSL which wasn't properly enabled for all platforms.
397 --- 2.0.10 2004/02/05
399 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
402 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
404 Added option -p <file> to make Generic Frontend Server to write PID file.
406 Added option -D to put Generic Frontend Server in background on its own.
408 Make ZOOM C recognize option "password". If unset, "pass" is used
409 (for backwards compatibility).
411 Fixed a bug in Generic Frontend Server that could make it crash if a
412 client sets characterSetNegotation bit, but didn't pass negotiation stuff
415 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
416 Must be issued before open, in order to be in effect.
418 --- 2.0.9-6 2004/01/12 Debian/Windows
420 Make the SRU server more picky WRT unknown params, etc.
422 Bug fix: ZOOM scan response didn't return displayTerm - when present.
424 New YAZ client command, options, that sets Z39.50 options.
426 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
427 options from a string of tokens (one token for each option bit).
429 Update SRW diagnostic code messages.
431 --- 2.0.9-5 2004/01/07 Debian/Windows
433 Handle user defined stylesheet for SRW/SRU.
435 --- 2.0.9-4 2004/01/06 Debian/Windows
437 Fix bug in decoding of Content-Length.
439 --- 2.0.9-3 2004/01/06 Debian/Windows
441 Fix a bug with decoding of XML packed records.
443 --- 2.0.9-2 2004/01/05 Debian only
445 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
447 Fix bug in SRW/SRU diagnostics decoding.
451 Fixed bug in Generic Frontend Server which could drop records exceeding
452 preferred message size. Reported and fixed by Irina Dijour.
454 Fixed calculation of package size for structured records in Generic
455 Frontend Server. Reported and fixed by Irina Dijour.
457 Fixed namespace for SRW/SRU diagnostics.
459 Fixed SEGV in yaz-client that occured for HTTP connection errors.
463 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
464 this version is incompatible with version 1.0 and older YAZ SRW/SRU
467 CQL changes to reflect recent changes to the specification:
468 * Documentation talks about context sets instead of index sets.
469 * Documentation talks about indexes instead of qualifiers.
470 * The CQL-to-PQF transformer's configuration file now uses
471 "index.set.name = <attributes>" instead of the old form
472 "qualifier.set.name = <attributes>". (Both forms are still
473 understood but the latter is deprecated.)
474 * CQL terms with no explicit index specified are now interpreted as
475 cql.serverChoice instead of srw.serverChoice (which of course
476 behaves exactly the same.)
480 MARC conversion can now generate ISO2709 output in another
481 character set. yaz-marcdump uses this facility if you invoke it
484 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
485 functions from there can be used from C++.
489 Frontend server now transfers memory from decoded packages to stream
492 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
493 references to show up.
495 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
496 the ZOOM Abstract API. The older names for the same options are still
497 also supported for the benefit of old applications.
499 ZOOM-C supports "implementationId" and "implementationVersion" options
500 to go along with "implementationName". These allow the user code to
501 specify identification strings to be sent to servers.
502 Add OID for the new ExtLite attribute set.
504 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
505 as requested/supplid by Ere Maijala <ere@atp.fi>
507 For generic frontend server, reverse the order of
508 "toolkit-supplied / application-supplied" strings sent as implementationId,
509 Name and Version. Also, remove the spaces around the slash. This brings
510 the GFS in line with the behaviour of ZOOM-C on the client side.
512 Add function ZOOM_scanset_display_term.
514 yaz-client shows scan displayTerm if present.
516 Utility yaz-iconv is now installed by default along with the man page
519 Extend configure check for OpenSSL to use pkg-config where available (such
522 Incorporate patch by Morten Bogeskov which allows a Unix file socket
523 server to specify uid/gid/mask for socket using the format
524 unix:[user=uid,][group=gid,][umask=mask,]file=path
525 If file= is omitted the existing format is assumed, e.g.
527 in which case the mask is 0666 (rw for everybody).
529 Major restructure of YAZ source. All source in libyaz is in src directory.
530 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
531 util (utility programs such as ASN.1 compiler, yaz-marcdump).
533 Added man page for utility yaz-marcdump (used to be called marcdump).
534 yaz-marcdump is installed by 'make install'.
536 Fixed a memory leak in Generic Frontend Server that occurred when decoding
537 of incoming package failed.
539 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
541 Change prototype of odr_perror: add const to message string.
543 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
545 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
546 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
547 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
548 DNS lookup. There should not be any compatibility problems with this
549 assuming that blocking=1 or 0 is used.
551 Fix bad reference in UNIX comstack in function cs_addrstr.
553 Fix for compilation on AIX.
555 The generic front-end server (server/seshigh.c) now supports returning
556 Init diagnostics to the client in User-information-field, in
557 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
562 Allow any CQL relation (not just all,any,exact,scr).
564 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
565 that features the same UI.
567 Implemented command update0 in YAZ client which is equivalent to
568 update but uses old of Ext Update ASN.1.
570 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
571 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
572 Previously no OID was used for this info.
574 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
575 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
576 returns 'malformed search term' otherwise.
578 SortResponse member resultCount now set to NULL in sort handler of
581 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
584 Add three new utility functions for translating OIDs between various
585 formats -- symbolic name such as "Usmarc", minus-1-terminated int
586 arrays and dotted strings such as "1.2.840.10003.9.5.1":
587 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
588 char *oid_to_dotstring(const int *oid, char *oidbuf);
589 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
591 Reverted modifications for ES Update definition for z_IU0Update
592 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
593 is back to YAZ 2.0.2.
595 String value attributes for CCL parser.
597 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
598 which their FirstSearch server returns in Init responses, sometimes
599 carrying useful diagnostic information when Init fails. This has the
600 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
601 "z39.50/oclcui.asn", where its definition is somewhat different from
602 what OCLC document on their web-site, as required to interoperate with
605 Support for anonymous authentication in yaz-client. Use the command
608 * Fix the OID of the Index Data-local "admin" Extended Service from
609 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
610 the 1000, which indicates a locally-defined OID, was a mistake.
614 Fix CCL directive @case handling so that it affects string match for
615 both CCL keywords and qualifiers.
617 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
618 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
619 Decoder has been updated with ASN.1 changes as listed in
620 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
621 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
622 z_IUUpdate, remains unchanged.
624 ZOOM_record_get may now return a record in a specific character set.
625 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
626 "from" is the character set of record as returned by target. "to" is
627 the character set to be returned. If omitted, "to" is UTF-8.
629 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
631 New ODR utility, odr_getelement, which returns name of element for
632 which encoding/decoding failed.
634 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
635 in cases where a required element was omitted.
637 Bug fix: some MARC8 sequences were not converted.
639 New ZOOM option "step" which specifies number of records to be
640 retrieved in one chunk. Used in conjunction with "start" and "count".
642 SRW support for yaz-client. Use scheme http: to use it, e.g.
645 yaz-client no longer does (un)intelligent character set conversions
646 by default. Can be enabled with charset and marc_charset commands.
648 xmalloc trace fix for 64-bit systems such as DEC alpha.
650 Solaris 2.6 compile fix.
652 New function, cql_strerror() translates SRW error codes, as returned
653 by cql_transform_error(), into human-readable English strings. Used
654 in yaz-client diagnostics when appropriate.
656 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
657 converts it into a type-1 query which is sent to the server. This
658 makes CQL available for use with all Z-servers, as opposed to the tiny
659 minority that can handle CQL queries themselves.
663 New Debian package layout similar to the Redhat Package layout.
665 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
666 and search result respectively.
670 Redhat package is now several packages: libyaz (runtime libraries),
671 libyaz-devel (development and documentation, and yaz (utility programs).
672 Package spec file by Morten Bøgeskov.
674 New member 'schema' in struct bend_fetch_rr which the name of requested
675 schema (SRW/SRU) for record (or NULL if none was given). The fetch
676 handler MAY set this to reflect the schema of the returned record.
678 New member 'display_term' in struct scan_entry. GFS now sets member entries
679 and allocates scan entries to be filled by user scan handler. In previous
680 version, entries member was allocated by the scan handler. That still works,
681 but the GFS will ignore member display_term - assuming it was NOT set by
682 the handler. The fact that the GFS now allocates the entries both allows
683 for new members and makes a scan handler easier to write.
685 Fix CQL lex buffer overflow.
687 SRW/SRU recordPacking. For SRW default recordPacking is string. For
688 SRU default recordPacking is string.
690 SRU protocol support for frontend server.
692 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
694 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
696 Added scan for the ZOOM shell (zoomsh).
700 * String Identifers for Schemas (Amendment 5).
701 http://lcweb.loc.gov/z3950/agency/amend/am5.html
702 Old definition for schema
703 Odr_oid *schema; /* OPT */
708 Z_InternationalString *uri;
709 #define Z_Schema_oid 1
710 #define Z_Schema_uri 2
713 * resultCount parameter to Sort Response (Amendment 1).
714 http://lcweb.loc.gov/z3950/agency/amend/am1.html
716 Support for SRW 1.0 over HTTP. This is an optional feature and
717 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
720 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
721 on the same port. SRW SearchRetrieveRequests are mapped
722 to bend_init,bend_search,bend_fetch,bend_close.
724 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
726 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
727 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
729 ZOOM connections are SRW based if schem http is used for hostname
730 in connect, e.g. z = ZOOM_connection_new("http://myserver");
731 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
733 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
734 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
735 distance=n, order=true/false, relation=le, prox unit=word. If
736 n is omitted, distance 1 is used.
738 Fixed problem with C compiler include path in wrong order.
740 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
741 on Solaris. Patch from Ko van der Sloot.
743 New MARC decode API. All new functions operate on a yaz_marc_t
744 handle. The most important new functions are: yaz_marc_create,
745 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
746 decode and destroy respectively. Decoder can produce formats
747 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
748 include/yaz/marcdisp.h.
750 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
751 to UTF-8, UCS-32, wchar_t or Latin-1.
753 * Prototypes for yaz_iconv_-functions moved to separate header
754 include/yaz/yaz-iconv.h.
756 Make a few private functions 'static' in unix.c. This prevents
757 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
759 For ZOOM connection, the options targetImplementation{Id,Name,Version}
760 are set when Init Response is received.
762 New function ZOOM_connection_error_x similar to ZOOM_connection_error
763 but returns diagnostic set as well.
765 New function yaz_strerror which is a portable wrapper for
766 strerror/strerror_r/GetLastMessage.
768 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
769 is returned for MARC. If type is "oai", then OAI MARC is returned.
771 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
776 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
778 Fix bad race conditions on SIGTERM and terminate gracefully in
781 Move retrieval (data1) module to Zebra since nobody seems to be
784 Add GRS-1 render for ZOOM using same format as yaz-client.
788 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
790 Fix broken ESpec handling in data1 module.
792 SGML reader parses comments and makes them part of the data1 tree.
794 Added several type casts so that YAZ compiles as C++ code.
796 ZOOM didn't handle PDU encoding failures properly.
798 Added more Bib-1 diagnostics (approved extensions).
800 GNU configure: better check for iconv.
802 More portable use of accept, getpeername. Check for socklen_t. Use
803 int/size_t if socklen_t is not defined.
807 PQF parser rejects bad queries - including those with extra
808 characters in them. PQF parser used to silently ignore that.
809 Cleaner API for PQF added, which allows you to get detailed
810 error information for bad queries (see yaz/pquery.h).
812 Fixed bug in ZOOM_record_get for type "database".
814 Implemented mini iconv library supporting conversions between
815 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
817 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
821 Fixed ZOOM C record cache so that preferredRecordSyntax and
822 elementSetName is used to check for already fetched records.
826 Added three members in bend_initrequest structure to facilitate
827 character set negotiation.
829 Fixed a bug in frontend server that could cause indefinite
830 loops under rare conditions.
832 Revised character set utilities (charneg.h) so that encoding
833 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
835 For PQF, directive @term <type> sets term type for Scan/Search.
836 Here <type> is general, string, numeric, null. The term type
837 is inherited - just like @attr.
839 New call odr_set_charset that sets character set conversion for
840 international-strings on a ODR stream. Prototype is:
841 int odr_set_charset(ODR o, const char *to, const char *from);
842 The InternationalString is still represented as C string in YAZ
843 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
844 won't). On the protocol level, you can use any encoding.
846 Support for UNIX sockets in ZOOM.
848 Solaris recv sometimes returns errno == ENOENT. It is treated as
849 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
851 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
852 both client and server. Code by Morten Bøgeskov.
856 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
857 that they can be used directly from Visual Basic. You must recompile
858 your windows APP if you're using ZOOM.
860 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
861 Commands "lang" and "charset" sets language and character set respectively.
862 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
863 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
865 Attributes from multiple CCL fields may be OR'ed rather than merged
866 using directive "@field or". Fields are still merged by default -
867 equivalent to "@field merge".
869 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
872 Fixed bug in zget for parameter ExtendedServicesResponse.
878 Added PQF feature: '@attr type=value' may be written as '@type=value'.
880 Client displays USR.1:SearchResult-1 (hits per term).
882 Additional Search Info for search in Generic Frontend Server.
884 Fixed CCL parsing of "field=s".
886 WIN32 installer - using the excellent NSIS software from nullsoft.
888 Fixed CCL parsing of "field = - <number>".
890 Added function yaz_marc_decode that decodes MARC for line mode
891 display or XML (similar to that used by JZKit).
893 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
894 Z39.50. But ISO/ILL was, however.
896 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
897 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
899 http://lcweb.loc.gov/z3950/agency/amend/am2.html
900 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
904 New YAZ client features: Command completion and new commands:
905 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
906 Code provided by Jacob Poulsen.
908 New call oid_trav, that visits all registered OIDs via callback.
910 Function ZOOM_record_get now returns const char pointer rather than
911 void pointer. It saves a lot of type casts.
913 For YAZ client, command "auth" now allows you to set authentication
914 in IdPass style. It is enabled when three tokens are given - order
915 is user, group and password.
917 Fix memory leaks in MARC record handling for ZOOM.
919 New option for YAZ client, -k <kilobytes> that sets
920 maximum record size. Similar to -k option for generic frontend
921 server and yaz-ztest.
923 More fixes for scan. Non-zero stepSize handled. OID's fixes.
925 Prefix query parser reports "fail" when bad attribute set is given.
927 Fix in MARC decoder. Proximity logging. Fix for attribute set
928 in scan handler for server. Patches by Shigeru Ishida.
930 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
933 Configure option --with-openssl=<dir> now works when a directory is
934 specified. Patch provided by Morten Bøgeskov.
936 New option for YAZ client, -u <auth>, that sets authentication.
938 ZOOM fix: error information was sometimes "missing", since error
939 was cleared/reset too when it shouldn't.
941 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
945 Scan for ZOOM API. New object ZOOM_scanset. New functions
946 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
947 ZOOM_scanset_destroy.
949 New ZOOM function, ZOOM_connection_last_event, that returns type
950 of last event (such as "receive data", "send data", "apdu received",
953 New ZOOM option, schema, that specifies schema for retrieval.
955 New CCL feature. Qualifiers can be aliases for one or more
956 other qualifiers (if more than one is given, OR is used).
958 ZOOM uses named result sets if target supports it.
960 Two new YAZ client commands: . (dot, which sources a script of YAZ
961 client commands), and ! (to execute shell command.). Implemented
964 Working on Debian packages.
968 YAZ client enables named result sets only if target supports it.
970 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
972 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
973 with key="host" to get same result.
975 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
976 Function Z3950_resultset_record(s) returns references to records
977 "owned" by resultset. To become owner use Z3950_record_clone.
979 Function z_ext_record handles Extended Services. Thanks to
984 CCL Parser fix: ignore token comma when dealing with and-lists.
986 Documentation updates for COMSTACK.
988 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
989 Changed prototype Z3950_records. For some functions, int parameters
990 were changed to size_t.
992 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
995 New MARC decode/display function, marc_display_exl, which properly rejects
996 non-ISO2709 records. YAZ client uses it.
1000 Fix bug: local attribute set wasn't set correctly in PQF strings.
1004 * Old Z39.50 codecs no longer supported.
1006 Added ZOOM C binding. See http://zoom.z3950.org/
1008 Renamed states for COMSTACKs to avoid confusion with events.
1010 Implemented cs_look and proper cs_rcvconnect.
1012 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1014 Configure detects POSIX threads on OpenBSD.
1016 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1017 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1019 When error is returned from present handler, non-surrogate diagnostic
1020 is returned in present response (and fetch handler is no longer called).
1022 * Minor adjustments to pquery parser (PQF). Token characters may be
1023 escaped by using backslash (C-style).
1025 PQF parser allows string attribute values to be specified. For @attr,
1026 non-numeric characters after the equal-sign are treated as strings
1027 (e.g. @attr 9=title).
1029 CCL trunction character may be defined (@truncation in file)
1031 * function zget_ExtendedServicesRequest sets waitAction to
1032 waitIfPossible (was wait).
1034 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1037 CCL operator names may be set in field definition files (CCL_bibset).
1038 See ccl/bib1 for an example.
1040 Fixes in ASN.1 compiler for C++ compatibility.
1042 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1043 and "op_or" to avoid conflict with C++.
1045 Fixed problem with GNU readline detection on Redhat 7.0.
1047 Added step-size for Scan backend handler.
1049 Fixed bug that made the frontend server crash when no attribute
1050 set was specified for scan.
1052 Front-end server automatically switches to original working directory
1053 when installed as an NT service. Previously -w had to be specified to
1056 Added extended attributes for retrieval module (data1), so that data1
1057 records carry d1_readXML/SGML attributes. d1_read also supports
1058 null-data rules ( <tag/>)
1060 On UNIX when POSIX threads are available, a separate library libyazthread
1061 is created. Programmers should link with that library and the yaz library
1062 when using threads. The reason for the split was that some applications
1063 on Linux, such as Apache, doesn't work well when using shared objects that
1066 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1067 (or any frontend server) in SSL mode by specifying ssl: followed by
1068 address. Only tested on UNIX.
1070 Added feature for CCL module. Virtual structure s=al or s=ol generates
1071 and-list and or-list respectively instead of phrase search.
1075 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1076 log_mask_str. This was done to avoid name conflicts with other libraries
1077 (such as other PHP extensions).
1079 Added raw OID member for preferred record syntax (request_format_raw)
1080 and returned record syntax (output_format_raw) for backend fetch method.
1082 Config file yaz-config now accepts options so that it returns specific
1083 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1085 Shared library support for UNIX using GNU libtool.
1087 * Modified backend interface. Request/Response struct's replaced by
1088 one read/write C struct. For example bend_fetchrequest and
1089 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1090 Every handler - even search has to be registered in bend_init
1091 handler. This means that the YAZ library no longer refers to
1092 external functions and it makes it possible to make the whole
1093 thing a single DLL/SO.
1095 Added Segment handler for backend server.
1097 Added Zmbol/Zebra administrative functions to YAZ client.
1099 Threaded frontend server on UNIX (when POSIX Threads are available).
1100 Starting the server with option -T enables multi-threading.
1104 Added configure option --enable-comp/disable-comp to control use
1105 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1106 located in sub directory asn.
1108 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1109 in ${exec_prefix}/bin along with the other programs yaz-client and
1112 GNU automake used to maintain makefiles.
1114 Added several OID's.
1116 Changed retrieval module so that we can load records with no abstract
1117 syntax defined. Tagpaths in these records are fully composed of string
1120 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1124 On UNIX, the generated makefile now supports a proper 'make install'.
1125 The prefix can be set via GNU configure to set the install location
1126 (default is /usr/local).
1128 * YAZ programs client and ztest were renamed to yaz-client and
1129 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1130 locations, such as /usr/bin,/usr/local/bin,etc.
1132 * YAZ Header files were moved from include to include/yaz. YAZ Header
1133 files are referred to as include <yaz/log.h> rather than <log.h>.
1134 The YAZ include path (-I ..) is therefore the same as before. Programmers
1135 should update their #include statements or use -Ipath/include/yaz
1136 instead. The main motivation for doing this change is that YAZ header files
1137 can be installed in "standard" locations /usr/include,/usr/local/include
1138 without introducing conflicts, since ALL YAZ header files are stored
1139 in subdirectory yaz (under /usr/include for example).
1141 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1142 rather than project/workspace files. We switched because project files
1143 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1146 Changed name of logging function, logf, to yaz_log, to prevent name
1147 clash with some math-log functions. The YAZ header log.h defines logf
1148 to yaz_log (#define) so there should be no incompatibilities by this
1151 Added bend_start/bend_stop handlers for server. These handler are
1152 called on start/stop of server. For windows they are called whenever
1153 a service is started/stopped.
1155 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1156 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1157 in util/yc.tcl. The auto-generated C code structures are, in a few
1158 cases, incompatible with the old decoders. There are differences in the
1159 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1160 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1161 The preprocessor variable ASN_COMPILED is defined when the compiled
1162 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1163 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1164 wish to use the old encoders/decoders you can specify --disable-yc
1167 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1168 version so that it supports both new - and old version of DB Update
1170 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1171 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1172 change. The name parameter can be set to 0 in which no name is specified
1173 for the construction. The macros odr_implicit and odr_explicit sets name
1174 parameter to zero for the construction involved. New macros
1175 odr_implicit_tag and odr_explicit_tag are similar to the others,
1176 except that a name parameter is added. For programmers' that don't use
1177 ODR they probably only need to change the call to z_APDU and z_External.
1179 Added access control facility by interfacing the TCP wrapper library.
1180 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1181 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1182 name of the daemon and enables the access control as specified in
1183 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1185 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1186 den Dool <H.M.vdnDool@kub.nl>.
1188 Added reference ID parameter to most functions in server API - refer
1189 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1191 Changed name of ccl library to libccl.a (was ccl.a).
1193 Fixed bug in decoder for Explain (Category TargetInfo).
1195 Added support for GNU readline in client. Thanks to Jacob Poulsen
1196 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1198 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1199 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1200 IMPLEMENTATION! This change was made to the development version before
1201 the ZIG decided to retract the amendment. If any users MUST be
1202 compatible with the original Update definition, PLEASE CONTACT US, and
1203 we will include a separate definition corresponding to the old Update
1204 ES. Note that because of the change to the ASN.1 of the
1205 TaskPackageRecordStructure we cannot define a single structure that
1206 will support both versions.
1208 * Added const modifier to buffer parameter for some ODR/BER encoding
1209 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1210 completeWAIS, odr_dumpBER.
1212 Fixed bug in client.c which caused a crash when a scanResponse didn't
1213 contain positionOfTerm.
1215 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1216 * will cause an error in a client if a non-YAZ target sends both a
1217 * list of Scan entries and non-surrogate diagnostics.
1219 Retrieval module enhancements. Tag sets may be typed in the reference
1220 to it. From the .abs-file the "tagset" directive takes a third optional
1221 integer type for the tag set referenced. From a .tag-file the "include"
1222 directive takes a third optional type as well. The old "type" directive
1223 in the tag set itself is still recognized but acts as the default type
1226 Backend interface change. Individual Scan terms returned from bend_scan
1227 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1228 in include/backend.h.
1230 Retrieval module enhancements. Multiple tag sets and attribute sets may
1231 be specified in abstract syntax specs. Revised the error/warning for
1232 logging messages reported by the retrieval module when reading the
1235 Object Identifier system (oid_..) changed. The API is backwards
1236 compatible but the oid-routines now allocates new OID's when needed.
1237 Raw OID's may be specified in oid_getvalbyname.
1239 YAZ now uses GNU configure to generate Makefile(s).
1241 * Minor changes in some of the member names of DeleteResultSetRequest and
1242 DeleteResultSetResponse. See include/proto.h.
1244 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1245 and added member 'languages' in TargetInfo (which was missing).
1247 Changed the way attribute sets are handled in the retrieval
1248 module. These are now cached, just like the abstract syntaxes
1251 Changed YAZ so that it links with compiled ASN.1.
1253 Added Explain-schema definitions and mapping routines. The following
1254 Explain categories have been implemented: AttributeDetails,
1255 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1257 Fixed minor bug in Windows version of Server Library.
1259 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1261 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1263 Added EXTERNAL: UNIverse Resource Report (non-standard).
1265 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1266 ENUMERATED and SET OF.
1268 * Added 'const' to some of the char pointer arguments for the
1269 functions, data1_read_node, data1_getelementbytagname,
1270 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1273 Fixed bug in data1_insert_taggeddata - the last_child member of
1274 parent wasn't initialised.
1276 * Changed data1_read_record and data1_read_node so that the supplied
1277 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1278 doesn't refer to any parts of the "SGML"-buffer.
1280 Fixed bug in server library (Windows version of statserv_remove).
1282 * Changed code so that it compiles as C++. The type definition
1283 of Odr_fun which is a member of Odr_arm was changed. The result is,
1284 that an explicit typecast is needed for the fun pointer when
1285 using Odr_arm - as in:
1286 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1288 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1290 Implemented the new structured date and time definition as approved
1291 by the ZIG. Added schemaId element to the specificTag in Espec-1
1292 (also approved at the last ZIG). Thanks to RVDM.
1294 Added some Object identifiers (RVDM).
1296 Changed the Update Extended Service (RVDM).
1298 Added command "refid" to client which specifies referenceId for
1299 the following requests.
1301 Implemented extended service handling for server. See ztest.c
1302 for an example as well as backend.h. New handlers are registerd
1303 in the Init handler.
1305 * Changed interface for sort in server.
1307 Added new members to statserv_options_block. It allows a server
1308 to read options from another source than just the command line. Thanks
1309 to Charles Woodfield.
1311 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1312 renamed to zboolean. Some C++ compilers complained about the name.
1314 Minor changes to gils.abs. Added index 's' (sort) on title
1315 and date/time-last-modified.
1317 --- 1.4pl2 1998/1/30
1319 Fixed bug in server library regarding inetd mode (-i). This bug
1320 was introduced by release 1.4.
1322 --- 1.4pl1 1998/1/29
1324 Added sort facility in client and backend server interface.
1326 Fixed problem with dependencies in Makefile(s).
1328 Fixed bugs for encoders/decoders of extended services and
1331 Implemented sub-tree feature for schemas. Sub-trees are
1332 referenced in *.abs-files. See explain.abs for an example
1333 of the use of this feature.
1335 Modified bib1.att; local attributes for ANY didn't include
1336 ANY itself (only affects use of the retrieval module).
1338 Fixed bug in plain SGML reader in function data1_read_node:
1339 tags with prefix "var" was incorrectly interpreted as variants.
1341 Added feature "sub-schemas" to enable references to - and definitions
1342 of - group of elements.
1344 * Removed member parent from type data1_element (in data1.h).
1346 Implemented function odr_nullval() that returns the value of
1349 * Removed member num_children from data1_node (in data1.h).
1351 Made NT service interface part of the server library. The
1352 function statserv_main uses the NT service when required and
1353 calls the statserv_start / statserv_close routines.
1355 Routine zget_SearchRequest and zget_PresentRequest fills
1356 resultSetName/Id member with "default" instead of "Default".
1358 Fixed memory leak in server. Request queue member wasn't freed.
1360 Fixed nmem_exit so that memory is freed.
1364 Revised the CCL parser utility to be thread safe.
1366 Added function, oid_ent_to_oid, to replace the function
1367 oid_getoidbyent, which is not thread safe.
1369 * Added nmem_init and nmem_exit to initialize and release
1370 NMEM resources. Function nmem_init should be called once in the
1371 initial thread before NMEM/ODR is used. statserv.c and client.c
1372 have been changed accordingly. The change was necessary to make
1373 NMEM thread safe. The NMEM memory pool is shared amongst threads
1374 in a process. Unix-based applications will still work fine without
1377 Added NT Services interface for the the Z39.50 (statserv) Server.
1378 Refer to the ztest.c source on the usage.
1380 Windows 95/NT port using MSVC5.0. Project files are included in the
1383 * Defined new 'global' handle for the retrieval (data1) system. The
1384 new handled, data1_handle, describes the state of the data1 system.
1385 This handle is passed as first argument to virtually all
1386 data1 related routines. The functions data1_create and data1_destroy
1387 creates and destroys a data1 handle respectively.
1389 Added ODR encode stream member to all backend request structures
1390 init, search, scan etc. This stream should be used to allocate all
1391 memory used for the response when thread safe operation is needed.
1393 Changed the comstack utility, cs_addstr, to be thread safe. The
1394 returned hostname string returned by the function is now part the
1397 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1398 function. The cs_straddr takes a COMSTACK handle as argument, so this
1399 function must be used after cs_create and before bind/connect.
1400 This function is thread safe.
1402 Moved test server to 'ztest' directory - generic server code still
1403 in 'server' directory.
1405 Made prefix query (pquery.c) utility thread safe.
1407 Added new function modifier YAZ_EXPORT to 'export' public DLL
1408 functions when using windows (see include/yconfig.h).
1410 Added definitions to the OID database (util/oid.c) (RVDM).
1412 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1414 Added call to ccl_rpn_delete in client program.
1416 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1417 release of RPN structure.
1419 Added support for C++, headers uses extern "C" for public definitions.
1420 With input from RVDM.
1422 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1423 Thanks to Ronald van der Meer (RVDM).
1425 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1427 Added support for private extensions to the OID database
1428 (oid_setprivateoids()). Thanks to RVDM.
1430 Added optional, physical ANY (key replication)
1432 Fixed null-reference problem in GRS-1 output filter.
1434 Proximity operator added to Prefix Query Format (PQF).
1436 In test client command "base" accepts multiple databases.
1438 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1442 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1444 Smallish bug-fixes in the new encoders/decoders (explain).
1446 Bug fixed in DeleteRequest.
1448 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1450 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1452 Added SOIF syntax (using private OID for now) to retrieval module and client.
1454 Added Update extended service.
1456 Added SearchResult-1 additional info structure.
1458 Added optional CCL (ISO8777) interpreter as separate module. Available
1461 --- 1.2 1996/6/10 (1st anniversary release)
1463 Added Summary record syntax. Lightly tested.
1465 Added OPAC record syntax. Untested.
1467 Added ResourceReport service encoders/decoders. Untested.
1469 Fixed bug in z_Unit - wrong tagging on unitSystem.
1471 Fixed bug in the DiagRecs decoder.
1473 Added options for max PDU size and session timeout to frontend-server.
1475 Added documentation of query-language parsers and other supporting utilities.
1477 [frontend-server] Added Attribute set to the bend_scanrequest API.
1479 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1480 surrogate diagnostics were generated.
1482 [retrieval] Allow multiple local values for attribute.
1484 [retrieval] Allow multiple attributes per element in .abs files. index type.
1486 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1488 --- 1.1pl2 1996/4/10
1490 Minor changes, mostly specific to Zebra's requirements (retrieval)
1494 Repaired bug in frontend server when running multiple listening
1495 endpoints in dynamic mode.
1497 z_External() now won't break if a known, ASN.1 value comes encapsulated
1498 in an octet-string. The value will pass through unmodified in an Odr_oct.
1500 Added a bit of code to the demo client to decode & display
1501 ASN.1-structured records represented in the octet-aligned branch of
1502 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1504 Added z_ext_getentbyref() to the ASN module. Doc updated.
1506 * Completed the SCAN definition in the ASN module. This may break SCAN
1507 code based on older YAZ-versions at compile-time. The fix is easy -
1510 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1511 under the SCAN definition. Remember to initialize this, server-people.
1513 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1514 that this does not extend to ODR and ASN.
1516 Comstack allows insertion of established socket (primarily for
1517 inetd-operation of servers). Doc updated.
1519 Front-end server can now start from the inetd in TCP mode. Doc
1522 --- 1.0pl4 1996/1/24
1526 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1527 the rank and record number.
1529 Adjustments to the frontend server.
1531 Fixed diagnostic BER dumper. It ignored the file argument.
1535 Various changes to retrieval module.
1537 Changed the union discriminators of the protocol files from enums to
1538 ints paired with #defines.
1540 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1543 *Changed operator in the RPN structure to 'roperator', again to avoid a
1546 Fixed problems in Explain decoders/encoders.
1548 --- 1.0pl2 1995/12/6
1550 Memory bug in log module fixed.
1552 --- 1.0pl1 1995/12/5
1554 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1556 Bug in Explain DatabaseInfo module fixed.
1558 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1562 The shift to v1.0 signals that we now consider the *core* functionality
1563 of YAZ reasonably stable (the core being more or less equivalent to
1564 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1565 tested (Explain not at all - though that will happen soonish).
1567 Minor changes to code to support Windows port.
1569 Various minor changes after we're getting to use GRS-1 & co. more.
1571 Added Espec-1 format.
1573 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1574 of the protocol and it cannot be selected when encoding (maps into 'string'
1575 when decoding). Needed to talk to some servers.
1577 Demo client can request simple element set names.
1579 Added Diagnostic Format encoders/decoders.
1581 Added simple Close handling to frontend server (no hooks for resource
1582 reporting yet), and demonstration client.
1584 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1586 --- 1.0b3 1995/08/24
1588 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1589 handled incorrectly when records were requested in the searchResponse. This
1590 will only affect you if you use the frontend-server.
1592 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1593 Test-client will ask for and print GRS1. Ztest will return dummy records
1596 Added Explain encoders/decoders to the service-level API. Untested.
1598 Added Extended Services: Item Order encoders and decoders to the Service-
1599 level API. Untested. We could use a recent copy of the pertinent bits
1600 of the ILL protocol to add those bits.
1602 Added diagnostic format 1 encoders/decoders to the service-level API.
1605 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1606 odr_cons.c, which causes a more correct output.
1608 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1609 was always set to 0 when no records were requested in the searchRequest.
1611 * Added better external-handling. This shouldn't harm old code that
1612 *encodes* externals. It can break code that looks for a
1613 'single-ASN1-type' representation, since those types that are known
1614 are now decoded immediately. Look at the SUTRS sample code in
1615 seshigh.c and client.c. Documentation updated.
1617 Handling of structured records in bend_fetchresponse. Length -1 marks
1618 structured record, type is deduced from format field.
1620 --- 1.0b2 1995/06/27
1621 Fairly quick maintenance release to add SUTRS support.
1623 Fixed handling of SUTRS records in the demonstration client.
1625 * Added format field to the bend_fetchrequest and bend_fetchresponce
1626 structures of the backend API (frontend server). When the record is
1627 returned, the value of the format field is mapped to an OID. The
1628 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1629 of the record. The special value VAL_NONE in the bend_request means
1630 that no specific format was requested by the client. Documentation
1631 updated accordingly. Test server (ztest) will return a fixed dummy
1632 SUTRS record if your client requests SUTRS.
1634 Documentation updated accordingly.
1636 You can now set external libraries and RANLIB support in the top-level
1640 First public release.
