1 Added 'exit' as synonym for 'quit' in yaz-client
3 Possible compatibility problems with earlier versions marked with '*'.
6 Added support for specifying srw resultset id + resultset TTL in a
7 Generic Frontend Server's search handler. Patch by Ko van der Sloot.
9 Added support for SRU POST. Patch by Ko van der Sloot.
11 Do not build the separate Multi-threaded (MT) library libyazthread.la.
12 Instead make the library libyaz.la multi-threaded. Threading as a whole
13 can still be disabled by configure option --disable-threads. Previosly,
14 with older GLIBCs there were problems with MT libs under Apache. This
15 has now been fixed a long time ago.
17 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
20 CQL module modified to be case insensitive for relations/indexes/operations.
22 Fixed bug in CQL transform code: incorrect value relationModifieder
25 Added 'show all' command for yaz-client which retrieves all results
28 Added new yaz-client, xmles, which takes a (private) OID and
29 a document to be sent as an extended service request.
31 Describe new yaz-client commands wait_response and set_auto_wait.
33 Increase TCP/IP listener backlog from 3 (which I am guessing was
34 copied from the SunOS manual entry way back when) so SOMAXCONN, so
35 that the socket will queue as many incoming connections as it's able
36 to handle ongoing connections. In other words, it will never now
37 refuse a connection that it would be able to handle merely because
38 it's not got around to accepting() enough of the pending connections
39 yet. This is the behaviour anyway under Linux, where the listen()
40 argument is ignored; but not under BSD and on systems such as
41 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
42 YAZ-based servers should now be uniform across operating systems in
45 yaz-marcdump uses 64-bit file access on some systems. This is enabled
46 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
47 This allows yaz-marcdump to read large MARC batches (>2 GB).
49 Modified all YAZ source files - except the source which is auto-generated
50 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
55 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
56 MARC output rather than returning "new" buffer.
58 yaz-client warns about unknown init options.
60 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
64 Added support for SRW sort in Generic Frontend Server. Patch
65 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
66 sortKeys - or NULL if none is provided.
68 Fixed bug #307: It was impossible to specify indefinite/no timeout
69 for ZOOM_event. Special timeout value -1 now means indefinite timeout
72 Added support for multiple languages and charsets to be specified in
73 ZOOM. Each charset/language is separated by a blank. If negotiation is
74 in effect in init-response, Option
75 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
76 Code based on patch by Vasiliy Osadchuk.
78 Fixed bug #306: infinite recursion that occurred when calling
79 yaz_log_level_init as the first call (before other log level or
82 Fixed bug in scan handling in front end server: if preferred-Position-In-
83 Response was non-present, a NULL pointer referece was performed.
87 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
88 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
89 now defined for all those error codes. So instead of putting 109 in
90 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
91 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
93 Modified the yaz-marcdump utility to skip garbage bytes between MARC
96 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
98 Program yaz-client now exits and produces an error message if multiple
99 Z39.50 servers are specified on the command line (none or one allowed
102 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
107 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
109 Fixed bug #272: Preserve spacing for CCL terms.
113 Added support for virtual hosts and multiple backend servers for
114 the YAZ frontend server. The configution is XML based and
115 support specificition of CQL to RPN mappings and explain information.
116 See section "Virtual Hosts" in the YAZ manual.
118 Extended OPAC display utility. OPAC display utility renders
119 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
120 to supplement yaz_marc_decode_wrbuf.
122 Fixed a bug in MARC decoder that could caused it to crash for some
123 invalid MARC records. More diagnostics and warnings where added in
124 XML output (warnings, etc are stored in comments).
126 --- 2.0.34 2005/02/08
128 Fixes for UNIX domain sockets. Bug #261.
130 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
132 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
133 Added yaz_marc_subfield_str which defines subfield lead string which is
134 used in YAZ_MARC_LINE format. Default string is blank+$. Added
135 yaz_marc_endline_str which defines end of fields string used in
136 YAZ_MARC_LINE format. Default string is newline.
138 Experimental support for MarcXChange. This format can be produced
139 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
140 http://www.bs.dk/standards/MarcXchange.xsd
142 Added yaz-client commands scansize that sets maximum number of
143 entries to be returned by scan.
145 --- 2.0.32 2005/01/11
147 Added support for SRW scan in yaz-client and Generic Frontend Server.
149 * Added whereInList member to SRW Scan Term.
151 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
153 Fixed NMEM system to return aligned blocks on the smallest boundaries
154 that are suitably aligned for all possible types on the particular
155 architecture YAZ is being built for.
157 --- 2.0.30 2005/01/04
159 Fixed numerious warnings that was issued with newer versions of GCC.
161 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
162 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
165 Make YAZ Generic Frontend Server slightly faster.
167 Enhance (and reduce) logging for Generic Frontend Server.
169 Revert YAZ log system so that it flushes every write operation
170 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
172 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
173 instead of LOG_, due to name clash with syslog(3). LOG_ are still
174 present. New applications should define YAZ_USE_NEW_LOG=1 - this
175 will effectively disable old definitions.
177 --- 2.0.28 2004/11/09
179 Added yaz_log_time_format which specifies log format using
182 Added yaz_log_module_level which returns mask for a module. Value
183 is non-zero mask a if module is enabled; zero if disabled.
185 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
186 in include/yaz/cql.h.
188 Fixed bug #176: Dont throw diagnostics on empty SRU args.
190 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
192 Fixed bug #172: RPM builds does not enable SSL.
194 Doxyfile.in part of dist. Doxyfile generated by configure.
196 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
197 are given and the corresponding component does not exist.
199 Extend CCL documentation in YAZ reference. Describe r=r.
201 --- 2.0.26 2004/10/01
203 Fixed MARC->MARCXML conversion to properly deal with
204 fields, subfields, indicators having non-ASCII characters.
206 Fixed MARC->MARCXML conversion so that ASCII control characters
207 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
210 Added YAZ GFS support for conversion from Z39.50 surrogate
211 diagnostics to SRW surrogate diagnostics.
213 Bug fix: YAZ GFS did not return schema in explainResponse.
215 --- 2.0.25 2004/09/30
217 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
218 now converts recordSchema to elementSetName as well as schema URI.
220 Fixed bug in COMSTACK that prevented HTTP request packages from being
223 --- 2.0.24 2004/09/29
225 Added CCL facility r=r "range" which is similar to r=o "ordered" but
226 does not require white-space before and after the dash in a range, e.g.
227 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
230 Fixed a few AC_TRY_LINK configure tests that did not operate properly
231 due to new GCC removing "redundant" code.
233 Added yaz-client commands scanpos and scanstep that sets preferred
234 position and step-size for scan.
236 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
238 Added CCL utility ccl_qual_buf which parses one or more CCL
239 spec lines in a buffer.
241 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
242 of name and value - ignoring empty lines and comments.
244 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
246 Added odr_get_element_path which returns current element path for an
247 ODR handle. This utility is useful in error handling or user-defined
250 Added ODR_PRINT utility odr_set_stream which is is a more generic
251 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
252 to a write function and pointer to close function. The close function - if
253 non-NULL - will be called during odr_destroy.
255 Fixed bug in CCL parser where truncation char was not removed from
256 right side when truncation=both was in effect.
258 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
261 --- 2.0.23 2004/08/11
263 Fix buffer overrun in CQL parser when dealing with proximity (%).
265 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
266 to UTF-8/UCS conversion is now only based on codetables.xml.
268 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
270 --- 2.0.22 2004/08/06
272 Add support for more "commit changes" in ZOOM (uses Extended Services).
274 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
277 Yet another small fix for configure of SSL.
279 --- 2.0.21 2004/05/14
281 Fix SSL libs for configure when --with-openssl=DIR is given.
283 --- 2.0.20 2004/05/10
285 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
287 SSL comstack now uses yaz.pem certificate file on server side
288 by default. Certificate filename can be configured by calling
289 comstack function cs_set_ssl_certificate_file before cs_bind is used.
291 Fix bug regarding multiple calls to ZOOM_connection_connect.
293 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
295 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
296 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
298 ZOOM now allows inspection of X509 peer certificate for verification.
299 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
301 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
302 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
303 as "modular" but it simplifies things.
305 Added cs_get_peer_certificate to that returns peer X509 PEM.
307 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
308 NULL if SSL is unavailable.
310 Documentation about MARC decoding tools.
312 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
314 --- 2.0.19 2004/03/30
316 Rename CHANGELOG to NEWS to follow GNU style packing.
318 Fix bug with missing initialization of member in init_diagnostics.
319 This bug affects threaded version of GFS server.
321 --- 2.0.18 2004/03/20
323 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
326 Ensure zlib.dll is packed with Windows install.
328 --- 2.0.17 2004/03/17
330 Fix encoding of xsd:string to use text instead of CDATA.
332 Fix endless loop in CQL parser with unbalanced ".
334 Use a more compact way to store MARC-8 conversion tables.
336 --- 2.0.16 2004/03/16 Debian only
338 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
341 Update CQL parser to use new CQL 1.1 modifiers for booleans and
346 --- 2.0.15 2004/03/01
348 Another fix for decoding of XML packed records.
350 --- 2.0.14 2004/02/25
352 Fixes for Chunked encoding. White space not ignored after length spec.
354 Update NS and use default NS for SRW diagnostic elements.
356 --- 2.0.13 2004/02/23
358 Implement ZOOM_resultset_cache_reset which resets record cache.
360 Implement ZOOM_resultset_sort which sorts a result set.
362 Implement chunked HTTP transfer.
364 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
366 --- 2.0.12 2004/02/16
368 Added member 'schema' to bend_explain_rr structure so that backend
369 can specify explain record identifier. Defaults to Zeerex 2.0.
371 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
373 --- 2.0.11 2004/02/16
375 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
378 Added init command for yaz-client which sends "extra" init request.
380 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
381 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
383 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
385 Make ZOOM error code for "invalid query".
387 Fixed compilation for SSL which wasn't properly enabled for all platforms.
389 --- 2.0.10 2004/02/05
391 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
394 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
396 Added option -p <file> to make Generic Frontend Server to write PID file.
398 Added option -D to put Generic Frontend Server in background on its own.
400 Make ZOOM C recognize option "password". If unset, "pass" is used
401 (for backwards compatibility).
403 Fixed a bug in Generic Frontend Server that could make it crash if a
404 client sets characterSetNegotation bit, but didn't pass negotiation stuff
407 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
408 Must be issued before open, in order to be in effect.
410 --- 2.0.9-6 2004/01/12 Debian/Windows
412 Make the SRU server more picky WRT unknown params, etc.
414 Bug fix: ZOOM scan response didn't return displayTerm - when present.
416 New YAZ client command, options, that sets Z39.50 options.
418 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
419 options from a string of tokens (one token for each option bit).
421 Update SRW diagnostic code messages.
423 --- 2.0.9-5 2004/01/07 Debian/Windows
425 Handle user defined stylesheet for SRW/SRU.
427 --- 2.0.9-4 2004/01/06 Debian/Windows
429 Fix bug in decoding of Content-Length.
431 --- 2.0.9-3 2004/01/06 Debian/Windows
433 Fix a bug with decoding of XML packed records.
435 --- 2.0.9-2 2004/01/05 Debian only
437 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
439 Fix bug in SRW/SRU diagnostics decoding.
443 Fixed bug in Generic Frontend Server which could drop records exceeding
444 preferred message size. Reported and fixed by Irina Dijour.
446 Fixed calculation of package size for structured records in Generic
447 Frontend Server. Reported and fixed by Irina Dijour.
449 Fixed namespace for SRW/SRU diagnostics.
451 Fixed SEGV in yaz-client that occured for HTTP connection errors.
455 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
456 this version is incompatible with version 1.0 and older YAZ SRW/SRU
459 CQL changes to reflect recent changes to the specification:
460 * Documentation talks about context sets instead of index sets.
461 * Documentation talks about indexes instead of qualifiers.
462 * The CQL-to-PQF transformer's configuration file now uses
463 "index.set.name = <attributes>" instead of the old form
464 "qualifier.set.name = <attributes>". (Both forms are still
465 understood but the latter is deprecated.)
466 * CQL terms with no explicit index specified are now interpreted as
467 cql.serverChoice instead of srw.serverChoice (which of course
468 behaves exactly the same.)
472 MARC conversion can now generate ISO2709 output in another
473 character set. yaz-marcdump uses this facility if you invoke it
476 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
477 functions from there can be used from C++.
481 Frontend server now transfers memory from decoded packages to stream
484 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
485 references to show up.
487 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
488 the ZOOM Abstract API. The older names for the same options are still
489 also supported for the benefit of old applications.
491 ZOOM-C supports "implementationId" and "implementationVersion" options
492 to go along with "implementationName". These allow the user code to
493 specify identification strings to be sent to servers.
494 Add OID for the new ExtLite attribute set.
496 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
497 as requested/supplid by Ere Maijala <ere@atp.fi>
499 For generic frontend server, reverse the order of
500 "toolkit-supplied / application-supplied" strings sent as implementationId,
501 Name and Version. Also, remove the spaces around the slash. This brings
502 the GFS in line with the behaviour of ZOOM-C on the client side.
504 Add function ZOOM_scanset_display_term.
506 yaz-client shows scan displayTerm if present.
508 Utility yaz-iconv is now installed by default along with the man page
511 Extend configure check for OpenSSL to use pkg-config where available (such
514 Incorporate patch by Morten Bogeskov which allows a Unix file socket
515 server to specify uid/gid/mask for socket using the format
516 unix:[user=uid,][group=gid,][umask=mask,]file=path
517 If file= is omitted the existing format is assumed, e.g.
519 in which case the mask is 0666 (rw for everybody).
521 Major restructure of YAZ source. All source in libyaz is in src directory.
522 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
523 util (utility programs such as ASN.1 compiler, yaz-marcdump).
525 Added man page for utility yaz-marcdump (used to be called marcdump).
526 yaz-marcdump is installed by 'make install'.
528 Fixed a memory leak in Generic Frontend Server that occurred when decoding
529 of incoming package failed.
531 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
533 Change prototype of odr_perror: add const to message string.
535 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
537 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
538 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
539 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
540 DNS lookup. There should not be any compatibility problems with this
541 assuming that blocking=1 or 0 is used.
543 Fix bad reference in UNIX comstack in function cs_addrstr.
545 Fix for compilation on AIX.
547 The generic front-end server (server/seshigh.c) now supports returning
548 Init diagnostics to the client in User-information-field, in
549 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
554 Allow any CQL relation (not just all,any,exact,scr).
556 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
557 that features the same UI.
559 Implemented command update0 in YAZ client which is equivalent to
560 update but uses old of Ext Update ASN.1.
562 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
563 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
564 Previously no OID was used for this info.
566 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
567 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
568 returns 'malformed search term' otherwise.
570 SortResponse member resultCount now set to NULL in sort handler of
573 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
576 Add three new utility functions for translating OIDs between various
577 formats -- symbolic name such as "Usmarc", minus-1-terminated int
578 arrays and dotted strings such as "1.2.840.10003.9.5.1":
579 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
580 char *oid_to_dotstring(const int *oid, char *oidbuf);
581 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
583 Reverted modifications for ES Update definition for z_IU0Update
584 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
585 is back to YAZ 2.0.2.
587 String value attributes for CCL parser.
589 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
590 which their FirstSearch server returns in Init responses, sometimes
591 carrying useful diagnostic information when Init fails. This has the
592 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
593 "z39.50/oclcui.asn", where its definition is somewhat different from
594 what OCLC document on their web-site, as required to interoperate with
597 Support for anonymous authentication in yaz-client. Use the command
600 * Fix the OID of the Index Data-local "admin" Extended Service from
601 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
602 the 1000, which indicates a locally-defined OID, was a mistake.
606 Fix CCL directive @case handling so that it affects string match for
607 both CCL keywords and qualifiers.
609 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
610 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
611 Decoder has been updated with ASN.1 changes as listed in
612 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
613 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
614 z_IUUpdate, remains unchanged.
616 ZOOM_record_get may now return a record in a specific character set.
617 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
618 "from" is the character set of record as returned by target. "to" is
619 the character set to be returned. If omitted, "to" is UTF-8.
621 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
623 New ODR utility, odr_getelement, which returns name of element for
624 which encoding/decoding failed.
626 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
627 in cases where a required element was omitted.
629 Bug fix: some MARC8 sequences were not converted.
631 New ZOOM option "step" which specifies number of records to be
632 retrieved in one chunk. Used in conjunction with "start" and "count".
634 SRW support for yaz-client. Use scheme http: to use it, e.g.
637 yaz-client no longer does (un)intelligent character set conversions
638 by default. Can be enabled with charset and marc_charset commands.
640 xmalloc trace fix for 64-bit systems such as DEC alpha.
642 Solaris 2.6 compile fix.
644 New function, cql_strerror() translates SRW error codes, as returned
645 by cql_transform_error(), into human-readable English strings. Used
646 in yaz-client diagnostics when appropriate.
648 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
649 converts it into a type-1 query which is sent to the server. This
650 makes CQL available for use with all Z-servers, as opposed to the tiny
651 minority that can handle CQL queries themselves.
655 New Debian package layout similar to the Redhat Package layout.
657 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
658 and search result respectively.
662 Redhat package is now several packages: libyaz (runtime libraries),
663 libyaz-devel (development and documentation, and yaz (utility programs).
664 Package spec file by Morten Bøgeskov.
666 New member 'schema' in struct bend_fetch_rr which the name of requested
667 schema (SRW/SRU) for record (or NULL if none was given). The fetch
668 handler MAY set this to reflect the schema of the returned record.
670 New member 'display_term' in struct scan_entry. GFS now sets member entries
671 and allocates scan entries to be filled by user scan handler. In previous
672 version, entries member was allocated by the scan handler. That still works,
673 but the GFS will ignore member display_term - assuming it was NOT set by
674 the handler. The fact that the GFS now allocates the entries both allows
675 for new members and makes a scan handler easier to write.
677 Fix CQL lex buffer overflow.
679 SRW/SRU recordPacking. For SRW default recordPacking is string. For
680 SRU default recordPacking is string.
682 SRU protocol support for frontend server.
684 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
686 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
688 Added scan for the ZOOM shell (zoomsh).
692 * String Identifers for Schemas (Amendment 5).
693 http://lcweb.loc.gov/z3950/agency/amend/am5.html
694 Old definition for schema
695 Odr_oid *schema; /* OPT */
700 Z_InternationalString *uri;
701 #define Z_Schema_oid 1
702 #define Z_Schema_uri 2
705 * resultCount parameter to Sort Response (Amendment 1).
706 http://lcweb.loc.gov/z3950/agency/amend/am1.html
708 Support for SRW 1.0 over HTTP. This is an optional feature and
709 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
712 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
713 on the same port. SRW SearchRetrieveRequests are mapped
714 to bend_init,bend_search,bend_fetch,bend_close.
716 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
718 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
719 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
721 ZOOM connections are SRW based if schem http is used for hostname
722 in connect, e.g. z = ZOOM_connection_new("http://myserver");
723 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
725 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
726 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
727 distance=n, order=true/false, relation=le, prox unit=word. If
728 n is omitted, distance 1 is used.
730 Fixed problem with C compiler include path in wrong order.
732 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
733 on Solaris. Patch from Ko van der Sloot.
735 New MARC decode API. All new functions operate on a yaz_marc_t
736 handle. The most important new functions are: yaz_marc_create,
737 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
738 decode and destroy respectively. Decoder can produce formats
739 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
740 include/yaz/marcdisp.h.
742 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
743 to UTF-8, UCS-32, wchar_t or Latin-1.
745 * Prototypes for yaz_iconv_-functions moved to separate header
746 include/yaz/yaz-iconv.h.
748 Make a few private functions 'static' in unix.c. This prevents
749 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
751 For ZOOM connection, the options targetImplementation{Id,Name,Version}
752 are set when Init Response is received.
754 New function ZOOM_connection_error_x similar to ZOOM_connection_error
755 but returns diagnostic set as well.
757 New function yaz_strerror which is a portable wrapper for
758 strerror/strerror_r/GetLastMessage.
760 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
761 is returned for MARC. If type is "oai", then OAI MARC is returned.
763 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
768 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
770 Fix bad race conditions on SIGTERM and terminate gracefully in
773 Move retrieval (data1) module to Zebra since nobody seems to be
776 Add GRS-1 render for ZOOM using same format as yaz-client.
780 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
782 Fix broken ESpec handling in data1 module.
784 SGML reader parses comments and makes them part of the data1 tree.
786 Added several type casts so that YAZ compiles as C++ code.
788 ZOOM didn't handle PDU encoding failures properly.
790 Added more Bib-1 diagnostics (approved extensions).
792 GNU configure: better check for iconv.
794 More portable use of accept, getpeername. Check for socklen_t. Use
795 int/size_t if socklen_t is not defined.
799 PQF parser rejects bad queries - including those with extra
800 characters in them. PQF parser used to silently ignore that.
801 Cleaner API for PQF added, which allows you to get detailed
802 error information for bad queries (see yaz/pquery.h).
804 Fixed bug in ZOOM_record_get for type "database".
806 Implemented mini iconv library supporting conversions between
807 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
809 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
813 Fixed ZOOM C record cache so that preferredRecordSyntax and
814 elementSetName is used to check for already fetched records.
818 Added three members in bend_initrequest structure to facilitate
819 character set negotiation.
821 Fixed a bug in frontend server that could cause indefinite
822 loops under rare conditions.
824 Revised character set utilities (charneg.h) so that encoding
825 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
827 For PQF, directive @term <type> sets term type for Scan/Search.
828 Here <type> is general, string, numeric, null. The term type
829 is inherited - just like @attr.
831 New call odr_set_charset that sets character set conversion for
832 international-strings on a ODR stream. Prototype is:
833 int odr_set_charset(ODR o, const char *to, const char *from);
834 The InternationalString is still represented as C string in YAZ
835 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
836 won't). On the protocol level, you can use any encoding.
838 Support for UNIX sockets in ZOOM.
840 Solaris recv sometimes returns errno == ENOENT. It is treated as
841 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
843 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
844 both client and server. Code by Morten Bøgeskov.
848 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
849 that they can be used directly from Visual Basic. You must recompile
850 your windows APP if you're using ZOOM.
852 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
853 Commands "lang" and "charset" sets language and character set respectively.
854 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
855 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
857 Attributes from multiple CCL fields may be OR'ed rather than merged
858 using directive "@field or". Fields are still merged by default -
859 equivalent to "@field merge".
861 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
864 Fixed bug in zget for parameter ExtendedServicesResponse.
870 Added PQF feature: '@attr type=value' may be written as '@type=value'.
872 Client displays USR.1:SearchResult-1 (hits per term).
874 Additional Search Info for search in Generic Frontend Server.
876 Fixed CCL parsing of "field=s".
878 WIN32 installer - using the excellent NSIS software from nullsoft.
880 Fixed CCL parsing of "field = - <number>".
882 Added function yaz_marc_decode that decodes MARC for line mode
883 display or XML (similar to that used by JZKit).
885 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
886 Z39.50. But ISO/ILL was, however.
888 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
889 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
891 http://lcweb.loc.gov/z3950/agency/amend/am2.html
892 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
896 New YAZ client features: Command completion and new commands:
897 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
898 Code provided by Jacob Poulsen.
900 New call oid_trav, that visits all registered OIDs via callback.
902 Function ZOOM_record_get now returns const char pointer rather than
903 void pointer. It saves a lot of type casts.
905 For YAZ client, command "auth" now allows you to set authentication
906 in IdPass style. It is enabled when three tokens are given - order
907 is user, group and password.
909 Fix memory leaks in MARC record handling for ZOOM.
911 New option for YAZ client, -k <kilobytes> that sets
912 maximum record size. Similar to -k option for generic frontend
913 server and yaz-ztest.
915 More fixes for scan. Non-zero stepSize handled. OID's fixes.
917 Prefix query parser reports "fail" when bad attribute set is given.
919 Fix in MARC decoder. Proximity logging. Fix for attribute set
920 in scan handler for server. Patches by Shigeru Ishida.
922 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
925 Configure option --with-openssl=<dir> now works when a directory is
926 specified. Patch provided by Morten Bøgeskov.
928 New option for YAZ client, -u <auth>, that sets authentication.
930 ZOOM fix: error information was sometimes "missing", since error
931 was cleared/reset too when it shouldn't.
933 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
937 Scan for ZOOM API. New object ZOOM_scanset. New functions
938 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
939 ZOOM_scanset_destroy.
941 New ZOOM function, ZOOM_connection_last_event, that returns type
942 of last event (such as "receive data", "send data", "apdu received",
945 New ZOOM option, schema, that specifies schema for retrieval.
947 New CCL feature. Qualifiers can be aliases for one or more
948 other qualifiers (if more than one is given, OR is used).
950 ZOOM uses named result sets if target supports it.
952 Two new YAZ client commands: . (dot, which sources a script of YAZ
953 client commands), and ! (to execute shell command.). Implemented
956 Working on Debian packages.
960 YAZ client enables named result sets only if target supports it.
962 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
964 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
965 with key="host" to get same result.
967 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
968 Function Z3950_resultset_record(s) returns references to records
969 "owned" by resultset. To become owner use Z3950_record_clone.
971 Function z_ext_record handles Extended Services. Thanks to
976 CCL Parser fix: ignore token comma when dealing with and-lists.
978 Documentation updates for COMSTACK.
980 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
981 Changed prototype Z3950_records. For some functions, int parameters
982 were changed to size_t.
984 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
987 New MARC decode/display function, marc_display_exl, which properly rejects
988 non-ISO2709 records. YAZ client uses it.
992 Fix bug: local attribute set wasn't set correctly in PQF strings.
996 * Old Z39.50 codecs no longer supported.
998 Added ZOOM C binding. See http://zoom.z3950.org/
1000 Renamed states for COMSTACKs to avoid confusion with events.
1002 Implemented cs_look and proper cs_rcvconnect.
1004 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1006 Configure detects POSIX threads on OpenBSD.
1008 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1009 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1011 When error is returned from present handler, non-surrogate diagnostic
1012 is returned in present response (and fetch handler is no longer called).
1014 * Minor adjustments to pquery parser (PQF). Token characters may be
1015 escaped by using backslash (C-style).
1017 PQF parser allows string attribute values to be specified. For @attr,
1018 non-numeric characters after the equal-sign are treated as strings
1019 (e.g. @attr 9=title).
1021 CCL trunction character may be defined (@truncation in file)
1023 * function zget_ExtendedServicesRequest sets waitAction to
1024 waitIfPossible (was wait).
1026 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1029 CCL operator names may be set in field definition files (CCL_bibset).
1030 See ccl/bib1 for an example.
1032 Fixes in ASN.1 compiler for C++ compatibility.
1034 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1035 and "op_or" to avoid conflict with C++.
1037 Fixed problem with GNU readline detection on Redhat 7.0.
1039 Added step-size for Scan backend handler.
1041 Fixed bug that made the frontend server crash when no attribute
1042 set was specified for scan.
1044 Front-end server automatically switches to original working directory
1045 when installed as an NT service. Previously -w had to be specified to
1048 Added extended attributes for retrieval module (data1), so that data1
1049 records carry d1_readXML/SGML attributes. d1_read also supports
1050 null-data rules ( <tag/>)
1052 On UNIX when POSIX threads are available, a separate library libyazthread
1053 is created. Programmers should link with that library and the yaz library
1054 when using threads. The reason for the split was that some applications
1055 on Linux, such as Apache, doesn't work well when using shared objects that
1058 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1059 (or any frontend server) in SSL mode by specifying ssl: followed by
1060 address. Only tested on UNIX.
1062 Added feature for CCL module. Virtual structure s=al or s=ol generates
1063 and-list and or-list respectively instead of phrase search.
1067 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1068 log_mask_str. This was done to avoid name conflicts with other libraries
1069 (such as other PHP extensions).
1071 Added raw OID member for preferred record syntax (request_format_raw)
1072 and returned record syntax (output_format_raw) for backend fetch method.
1074 Config file yaz-config now accepts options so that it returns specific
1075 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1077 Shared library support for UNIX using GNU libtool.
1079 * Modified backend interface. Request/Response struct's replaced by
1080 one read/write C struct. For example bend_fetchrequest and
1081 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1082 Every handler - even search has to be registered in bend_init
1083 handler. This means that the YAZ library no longer refers to
1084 external functions and it makes it possible to make the whole
1085 thing a single DLL/SO.
1087 Added Segment handler for backend server.
1089 Added Zmbol/Zebra administrative functions to YAZ client.
1091 Threaded frontend server on UNIX (when POSIX Threads are available).
1092 Starting the server with option -T enables multi-threading.
1096 Added configure option --enable-comp/disable-comp to control use
1097 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1098 located in sub directory asn.
1100 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1101 in ${exec_prefix}/bin along with the other programs yaz-client and
1104 GNU automake used to maintain makefiles.
1106 Added several OID's.
1108 Changed retrieval module so that we can load records with no abstract
1109 syntax defined. Tagpaths in these records are fully composed of string
1112 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1116 On UNIX, the generated makefile now supports a proper 'make install'.
1117 The prefix can be set via GNU configure to set the install location
1118 (default is /usr/local).
1120 * YAZ programs client and ztest were renamed to yaz-client and
1121 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1122 locations, such as /usr/bin,/usr/local/bin,etc.
1124 * YAZ Header files were moved from include to include/yaz. YAZ Header
1125 files are referred to as include <yaz/log.h> rather than <log.h>.
1126 The YAZ include path (-I ..) is therefore the same as before. Programmers
1127 should update their #include statements or use -Ipath/include/yaz
1128 instead. The main motivation for doing this change is that YAZ header files
1129 can be installed in "standard" locations /usr/include,/usr/local/include
1130 without introducing conflicts, since ALL YAZ header files are stored
1131 in subdirectory yaz (under /usr/include for example).
1133 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1134 rather than project/workspace files. We switched because project files
1135 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1138 Changed name of logging function, logf, to yaz_log, to prevent name
1139 clash with some math-log functions. The YAZ header log.h defines logf
1140 to yaz_log (#define) so there should be no incompatibilities by this
1143 Added bend_start/bend_stop handlers for server. These handler are
1144 called on start/stop of server. For windows they are called whenever
1145 a service is started/stopped.
1147 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1148 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1149 in util/yc.tcl. The auto-generated C code structures are, in a few
1150 cases, incompatible with the old decoders. There are differences in the
1151 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1152 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1153 The preprocessor variable ASN_COMPILED is defined when the compiled
1154 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1155 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1156 wish to use the old encoders/decoders you can specify --disable-yc
1159 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1160 version so that it supports both new - and old version of DB Update
1162 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1163 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1164 change. The name parameter can be set to 0 in which no name is specified
1165 for the construction. The macros odr_implicit and odr_explicit sets name
1166 parameter to zero for the construction involved. New macros
1167 odr_implicit_tag and odr_explicit_tag are similar to the others,
1168 except that a name parameter is added. For programmers' that don't use
1169 ODR they probably only need to change the call to z_APDU and z_External.
1171 Added access control facility by interfacing the TCP wrapper library.
1172 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1173 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1174 name of the daemon and enables the access control as specified in
1175 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1177 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1178 den Dool <H.M.vdnDool@kub.nl>.
1180 Added reference ID parameter to most functions in server API - refer
1181 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1183 Changed name of ccl library to libccl.a (was ccl.a).
1185 Fixed bug in decoder for Explain (Category TargetInfo).
1187 Added support for GNU readline in client. Thanks to Jacob Poulsen
1188 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1190 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1191 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1192 IMPLEMENTATION! This change was made to the development version before
1193 the ZIG decided to retract the amendment. If any users MUST be
1194 compatible with the original Update definition, PLEASE CONTACT US, and
1195 we will include a separate definition corresponding to the old Update
1196 ES. Note that because of the change to the ASN.1 of the
1197 TaskPackageRecordStructure we cannot define a single structure that
1198 will support both versions.
1200 * Added const modifier to buffer parameter for some ODR/BER encoding
1201 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1202 completeWAIS, odr_dumpBER.
1204 Fixed bug in client.c which caused a crash when a scanResponse didn't
1205 contain positionOfTerm.
1207 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1208 * will cause an error in a client if a non-YAZ target sends both a
1209 * list of Scan entries and non-surrogate diagnostics.
1211 Retrieval module enhancements. Tag sets may be typed in the reference
1212 to it. From the .abs-file the "tagset" directive takes a third optional
1213 integer type for the tag set referenced. From a .tag-file the "include"
1214 directive takes a third optional type as well. The old "type" directive
1215 in the tag set itself is still recognized but acts as the default type
1218 Backend interface change. Individual Scan terms returned from bend_scan
1219 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1220 in include/backend.h.
1222 Retrieval module enhancements. Multiple tag sets and attribute sets may
1223 be specified in abstract syntax specs. Revised the error/warning for
1224 logging messages reported by the retrieval module when reading the
1227 Object Identifier system (oid_..) changed. The API is backwards
1228 compatible but the oid-routines now allocates new OID's when needed.
1229 Raw OID's may be specified in oid_getvalbyname.
1231 YAZ now uses GNU configure to generate Makefile(s).
1233 * Minor changes in some of the member names of DeleteResultSetRequest and
1234 DeleteResultSetResponse. See include/proto.h.
1236 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1237 and added member 'languages' in TargetInfo (which was missing).
1239 Changed the way attribute sets are handled in the retrieval
1240 module. These are now cached, just like the abstract syntaxes
1243 Changed YAZ so that it links with compiled ASN.1.
1245 Added Explain-schema definitions and mapping routines. The following
1246 Explain categories have been implemented: AttributeDetails,
1247 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1249 Fixed minor bug in Windows version of Server Library.
1251 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1253 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1255 Added EXTERNAL: UNIverse Resource Report (non-standard).
1257 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1258 ENUMERATED and SET OF.
1260 * Added 'const' to some of the char pointer arguments for the
1261 functions, data1_read_node, data1_getelementbytagname,
1262 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1265 Fixed bug in data1_insert_taggeddata - the last_child member of
1266 parent wasn't initialised.
1268 * Changed data1_read_record and data1_read_node so that the supplied
1269 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1270 doesn't refer to any parts of the "SGML"-buffer.
1272 Fixed bug in server library (Windows version of statserv_remove).
1274 * Changed code so that it compiles as C++. The type definition
1275 of Odr_fun which is a member of Odr_arm was changed. The result is,
1276 that an explicit typecast is needed for the fun pointer when
1277 using Odr_arm - as in:
1278 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1280 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1282 Implemented the new structured date and time definition as approved
1283 by the ZIG. Added schemaId element to the specificTag in Espec-1
1284 (also approved at the last ZIG). Thanks to RVDM.
1286 Added some Object identifiers (RVDM).
1288 Changed the Update Extended Service (RVDM).
1290 Added command "refid" to client which specifies referenceId for
1291 the following requests.
1293 Implemented extended service handling for server. See ztest.c
1294 for an example as well as backend.h. New handlers are registerd
1295 in the Init handler.
1297 * Changed interface for sort in server.
1299 Added new members to statserv_options_block. It allows a server
1300 to read options from another source than just the command line. Thanks
1301 to Charles Woodfield.
1303 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1304 renamed to zboolean. Some C++ compilers complained about the name.
1306 Minor changes to gils.abs. Added index 's' (sort) on title
1307 and date/time-last-modified.
1309 --- 1.4pl2 1998/1/30
1311 Fixed bug in server library regarding inetd mode (-i). This bug
1312 was introduced by release 1.4.
1314 --- 1.4pl1 1998/1/29
1316 Added sort facility in client and backend server interface.
1318 Fixed problem with dependencies in Makefile(s).
1320 Fixed bugs for encoders/decoders of extended services and
1323 Implemented sub-tree feature for schemas. Sub-trees are
1324 referenced in *.abs-files. See explain.abs for an example
1325 of the use of this feature.
1327 Modified bib1.att; local attributes for ANY didn't include
1328 ANY itself (only affects use of the retrieval module).
1330 Fixed bug in plain SGML reader in function data1_read_node:
1331 tags with prefix "var" was incorrectly interpreted as variants.
1333 Added feature "sub-schemas" to enable references to - and definitions
1334 of - group of elements.
1336 * Removed member parent from type data1_element (in data1.h).
1338 Implemented function odr_nullval() that returns the value of
1341 * Removed member num_children from data1_node (in data1.h).
1343 Made NT service interface part of the server library. The
1344 function statserv_main uses the NT service when required and
1345 calls the statserv_start / statserv_close routines.
1347 Routine zget_SearchRequest and zget_PresentRequest fills
1348 resultSetName/Id member with "default" instead of "Default".
1350 Fixed memory leak in server. Request queue member wasn't freed.
1352 Fixed nmem_exit so that memory is freed.
1356 Revised the CCL parser utility to be thread safe.
1358 Added function, oid_ent_to_oid, to replace the function
1359 oid_getoidbyent, which is not thread safe.
1361 * Added nmem_init and nmem_exit to initialize and release
1362 NMEM resources. Function nmem_init should be called once in the
1363 initial thread before NMEM/ODR is used. statserv.c and client.c
1364 have been changed accordingly. The change was necessary to make
1365 NMEM thread safe. The NMEM memory pool is shared amongst threads
1366 in a process. Unix-based applications will still work fine without
1369 Added NT Services interface for the the Z39.50 (statserv) Server.
1370 Refer to the ztest.c source on the usage.
1372 Windows 95/NT port using MSVC5.0. Project files are included in the
1375 * Defined new 'global' handle for the retrieval (data1) system. The
1376 new handled, data1_handle, describes the state of the data1 system.
1377 This handle is passed as first argument to virtually all
1378 data1 related routines. The functions data1_create and data1_destroy
1379 creates and destroys a data1 handle respectively.
1381 Added ODR encode stream member to all backend request structures
1382 init, search, scan etc. This stream should be used to allocate all
1383 memory used for the response when thread safe operation is needed.
1385 Changed the comstack utility, cs_addstr, to be thread safe. The
1386 returned hostname string returned by the function is now part the
1389 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1390 function. The cs_straddr takes a COMSTACK handle as argument, so this
1391 function must be used after cs_create and before bind/connect.
1392 This function is thread safe.
1394 Moved test server to 'ztest' directory - generic server code still
1395 in 'server' directory.
1397 Made prefix query (pquery.c) utility thread safe.
1399 Added new function modifier YAZ_EXPORT to 'export' public DLL
1400 functions when using windows (see include/yconfig.h).
1402 Added definitions to the OID database (util/oid.c) (RVDM).
1404 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1406 Added call to ccl_rpn_delete in client program.
1408 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1409 release of RPN structure.
1411 Added support for C++, headers uses extern "C" for public definitions.
1412 With input from RVDM.
1414 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1415 Thanks to Ronald van der Meer (RVDM).
1417 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1419 Added support for private extensions to the OID database
1420 (oid_setprivateoids()). Thanks to RVDM.
1422 Added optional, physical ANY (key replication)
1424 Fixed null-reference problem in GRS-1 output filter.
1426 Proximity operator added to Prefix Query Format (PQF).
1428 In test client command "base" accepts multiple databases.
1430 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1434 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1436 Smallish bug-fixes in the new encoders/decoders (explain).
1438 Bug fixed in DeleteRequest.
1440 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1442 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1444 Added SOIF syntax (using private OID for now) to retrieval module and client.
1446 Added Update extended service.
1448 Added SearchResult-1 additional info structure.
1450 Added optional CCL (ISO8777) interpreter as separate module. Available
1453 --- 1.2 1996/6/10 (1st anniversary release)
1455 Added Summary record syntax. Lightly tested.
1457 Added OPAC record syntax. Untested.
1459 Added ResourceReport service encoders/decoders. Untested.
1461 Fixed bug in z_Unit - wrong tagging on unitSystem.
1463 Fixed bug in the DiagRecs decoder.
1465 Added options for max PDU size and session timeout to frontend-server.
1467 Added documentation of query-language parsers and other supporting utilities.
1469 [frontend-server] Added Attribute set to the bend_scanrequest API.
1471 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1472 surrogate diagnostics were generated.
1474 [retrieval] Allow multiple local values for attribute.
1476 [retrieval] Allow multiple attributes per element in .abs files. index type.
1478 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1480 --- 1.1pl2 1996/4/10
1482 Minor changes, mostly specific to Zebra's requirements (retrieval)
1486 Repaired bug in frontend server when running multiple listening
1487 endpoints in dynamic mode.
1489 z_External() now won't break if a known, ASN.1 value comes encapsulated
1490 in an octet-string. The value will pass through unmodified in an Odr_oct.
1492 Added a bit of code to the demo client to decode & display
1493 ASN.1-structured records represented in the octet-aligned branch of
1494 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1496 Added z_ext_getentbyref() to the ASN module. Doc updated.
1498 * Completed the SCAN definition in the ASN module. This may break SCAN
1499 code based on older YAZ-versions at compile-time. The fix is easy -
1502 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1503 under the SCAN definition. Remember to initialize this, server-people.
1505 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1506 that this does not extend to ODR and ASN.
1508 Comstack allows insertion of established socket (primarily for
1509 inetd-operation of servers). Doc updated.
1511 Front-end server can now start from the inetd in TCP mode. Doc
1514 --- 1.0pl4 1996/1/24
1518 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1519 the rank and record number.
1521 Adjustments to the frontend server.
1523 Fixed diagnostic BER dumper. It ignored the file argument.
1527 Various changes to retrieval module.
1529 Changed the union discriminators of the protocol files from enums to
1530 ints paired with #defines.
1532 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1535 *Changed operator in the RPN structure to 'roperator', again to avoid a
1538 Fixed problems in Explain decoders/encoders.
1540 --- 1.0pl2 1995/12/6
1542 Memory bug in log module fixed.
1544 --- 1.0pl1 1995/12/5
1546 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1548 Bug in Explain DatabaseInfo module fixed.
1550 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1554 The shift to v1.0 signals that we now consider the *core* functionality
1555 of YAZ reasonably stable (the core being more or less equivalent to
1556 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1557 tested (Explain not at all - though that will happen soonish).
1559 Minor changes to code to support Windows port.
1561 Various minor changes after we're getting to use GRS-1 & co. more.
1563 Added Espec-1 format.
1565 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1566 of the protocol and it cannot be selected when encoding (maps into 'string'
1567 when decoding). Needed to talk to some servers.
1569 Demo client can request simple element set names.
1571 Added Diagnostic Format encoders/decoders.
1573 Added simple Close handling to frontend server (no hooks for resource
1574 reporting yet), and demonstration client.
1576 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1578 --- 1.0b3 1995/08/24
1580 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1581 handled incorrectly when records were requested in the searchResponse. This
1582 will only affect you if you use the frontend-server.
1584 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1585 Test-client will ask for and print GRS1. Ztest will return dummy records
1588 Added Explain encoders/decoders to the service-level API. Untested.
1590 Added Extended Services: Item Order encoders and decoders to the Service-
1591 level API. Untested. We could use a recent copy of the pertinent bits
1592 of the ILL protocol to add those bits.
1594 Added diagnostic format 1 encoders/decoders to the service-level API.
1597 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1598 odr_cons.c, which causes a more correct output.
1600 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1601 was always set to 0 when no records were requested in the searchRequest.
1603 * Added better external-handling. This shouldn't harm old code that
1604 *encodes* externals. It can break code that looks for a
1605 'single-ASN1-type' representation, since those types that are known
1606 are now decoded immediately. Look at the SUTRS sample code in
1607 seshigh.c and client.c. Documentation updated.
1609 Handling of structured records in bend_fetchresponse. Length -1 marks
1610 structured record, type is deduced from format field.
1612 --- 1.0b2 1995/06/27
1613 Fairly quick maintenance release to add SUTRS support.
1615 Fixed handling of SUTRS records in the demonstration client.
1617 * Added format field to the bend_fetchrequest and bend_fetchresponce
1618 structures of the backend API (frontend server). When the record is
1619 returned, the value of the format field is mapped to an OID. The
1620 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1621 of the record. The special value VAL_NONE in the bend_request means
1622 that no specific format was requested by the client. Documentation
1623 updated accordingly. Test server (ztest) will return a fixed dummy
1624 SUTRS record if your client requests SUTRS.
1626 Documentation updated accordingly.
1628 You can now set external libraries and RANLIB support in the top-level
1632 First public release.
