1 Possible compatibility problems with earlier versions marked with '*'.
3 Fixed bug in CCL parser where truncation char was not removed when
4 truncation=both was in effect.
6 Added odr_set_stream which is is a more generic to odr_setprint.
7 odr_set_stream takes a stream handle, pointer to puts function and
8 pointer to close function. The close function - if non-NULL - will be
9 called during odr_destroy.
11 Fixed CQL parser to use unsigned chars (occurred on MS .NET).
15 Fix buffer overrun in CQL parser when dealing with proximity (%).
17 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
18 to UTF-8/UCS conversion is now only based on codetables.xml.
20 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
24 Add support for more "commit changes" in ZOOM (uses Extended Services).
26 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
29 Yet another small fix for configure of SSL.
33 Fix SSL libs for configure when --with-openssl=DIR is given.
37 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
39 SSL comstack now uses yaz.pem certificate file on server side
40 by default. Certificate filename can be configured by calling
41 comstack function cs_set_ssl_certificate_file before cs_bind is used.
43 Fix bug regarding multiple calls to ZOOM_connection_connect.
45 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
47 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
48 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
50 ZOOM now allows inspection of X509 peer certificate for verification.
51 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
53 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
54 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
55 as "modular" but it simplifies things.
57 Added cs_get_peer_certificate to that returns peer X509 PEM.
59 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
60 NULL if SSL is unavailable.
62 Documentation about MARC decoding tools.
64 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
68 Rename CHANGELOG to NEWS to follow GNU style packing.
70 Fix bug with missing initialization of member in init_diagnostics.
71 This bug affects threaded version of GFS server.
75 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
78 Ensure zlib.dll is packed with Windows install.
82 Fix encoding of xsd:string to use text instead of CDATA.
84 Fix endless loop in CQL parser with unbalanced ".
86 Use a more compact way to store MARC-8 conversion tables.
88 --- 2.0.16 2004/03/16 Debian only
90 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
93 Update CQL parser to use new CQL 1.1 modifiers for booleans and
100 Another fix for decoding of XML packed records.
102 --- 2.0.14 2004/02/25
104 Fixes for Chunked encoding. White space not ignored after length spec.
106 Update NS and use default NS for SRW diagnostic elements.
108 --- 2.0.13 2004/02/23
110 Implement ZOOM_resultset_cache_reset which resets record cache.
112 Implement ZOOM_resultset_sort which sorts a result set.
114 Implement chunked HTTP transfer.
116 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
118 --- 2.0.12 2004/02/16
120 Added member 'schema' to bend_explain_rr structure so that backend
121 can specify explain record identifier. Defaults to Zeerex 2.0.
123 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
125 --- 2.0.11 2004/02/16
127 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
130 Added init command for yaz-client which sends "extra" init request.
132 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
133 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
135 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
137 Make ZOOM error code for "invalid query".
139 Fixed compilation for SSL which wasn't properly enabled for all platforms.
141 --- 2.0.10 2004/02/05
143 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
146 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
148 Added option -p <file> to make Generic Frontend Server to write PID file.
150 Added option -D to put Generic Frontend Server in background on its own.
152 Make ZOOM C recognize option "password". If unset, "pass" is used
153 (for backwards compatibility).
155 Fixed a bug in Generic Frontend Server that could make it crash if a
156 client sets characterSetNegotation bit, but didn't pass negotiation stuff
159 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
160 Must be issued before open, in order to be in effect.
162 --- 2.0.9-6 2004/01/12 Debian/Windows
164 Make the SRU server more picky WRT unknown params, etc.
166 Bug fix: ZOOM scan response didn't return displayTerm - when present.
168 New YAZ client command, options, that sets Z39.50 options.
170 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
171 options from a string of tokens (one token for each option bit).
173 Update SRW diagnostic code messages.
175 --- 2.0.9-5 2004/01/07 Debian/Windows
177 Handle user defined stylesheet for SRW/SRU.
179 --- 2.0.9-4 2004/01/06 Debian/Windows
181 Fix bug in decoding of Content-Length.
183 --- 2.0.9-3 2004/01/06 Debian/Windows
185 Fix a bug with decoding of XML packed records.
187 --- 2.0.9-2 2004/01/05 Debian only
189 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
191 Fix bug in SRW/SRU diagnostics decoding.
195 Fixed bug in Generic Frontend Server which could drop records exceeding
196 preferred message size. Reported and fixed by Irina Dijour.
198 Fixed calculation of package size for structured records in Generic
199 Frontend Server. Reported and fixed by Irina Dijour.
201 Fixed namespace for SRW/SRU diagnostics.
203 Fixed SEGV in yaz-client that occured for HTTP connection errors.
207 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
208 this version is incompatible with version 1.0 and older YAZ SRW/SRU
211 CQL changes to reflect recent changes to the specification:
212 * Documentation talks about context sets instead of index sets.
213 * Documentation talks about indexes instead of qualifiers.
214 * The CQL-to-PQF transformer's configuration file now uses
215 "index.set.name = <attributes>" instead of the old form
216 "qualifier.set.name = <attributes>". (Both forms are still
217 understood but the latter is deprecated.)
218 * CQL terms with no explicit index specified are now interpreted as
219 cql.serverChoice instead of srw.serverChoice (which of course
220 behaves exactly the same.)
224 MARC conversion can now generate ISO2709 output in another
225 character set. yaz-marcdump uses this facility if you invoke it
228 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
229 functions from there can be used from C++.
233 Frontend server now transfers memory from decoded packages to stream
236 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
237 references to show up.
239 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
240 the ZOOM Abstract API. The older names for the same options are still
241 also supported for the benefit of old applications.
243 ZOOM-C supports "implementationId" and "implementationVersion" options
244 to go along with "implementationName". These allow the user code to
245 specify identification strings to be sent to servers.
246 Add OID for the new ExtLite attribute set.
248 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
249 as requested/supplid by Ere Maijala <ere@atp.fi>
251 For generic frontend server, reverse the order of
252 "toolkit-supplied / application-supplied" strings sent as implementationId,
253 Name and Version. Also, remove the spaces around the slash. This brings
254 the GFS in line with the behaviour of ZOOM-C on the client side.
256 Add function ZOOM_scanset_display_term.
258 yaz-client shows scan displayTerm if present.
260 Utility yaz-iconv is now installed by default along with the man page
263 Extend configure check for OpenSSL to use pkg-config where available (such
266 Incorporate patch by Morten Bogeskov which allows a Unix file socket
267 server to specify uid/gid/mask for socket using the format
268 unix:[user=uid,][group=gid,][umask=mask,]file=path
269 If file= is omitted the existing format is assumed, e.g.
271 in which case the mask is 0666 (rw for everybody).
273 Major restructure of YAZ source. All source in libyaz is in src directory.
274 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
275 util (utility programs such as ASN.1 compiler, yaz-marcdump).
277 Added man page for utility yaz-marcdump (used to be called marcdump).
278 yaz-marcdump is installed by 'make install'.
280 Fixed a memory leak in Generic Frontend Server that occurred when decoding
281 of incoming package failed.
283 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
285 Change prototype of odr_perror: add const to message string.
287 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
289 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
290 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
291 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
292 DNS lookup. There should not be any compatibility problems with this
293 assuming that blocking=1 or 0 is used.
295 Fix bad reference in UNIX comstack in function cs_addrstr.
297 Fix for compilation on AIX.
299 The generic front-end server (server/seshigh.c) now supports returning
300 Init diagnostics to the client in User-information-field, in
301 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
306 Allow any CQL relation (not just all,any,exact,scr).
308 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
309 that features the same UI.
311 Implemented command update0 in YAZ client which is equivalent to
312 update but uses old of Ext Update ASN.1.
314 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
315 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
316 Previously no OID was used for this info.
318 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
319 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
320 returns 'malformed search term' otherwise.
322 SortResponse member resultCount now set to NULL in sort handler of
325 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
328 Add three new utility functions for translating OIDs between various
329 formats -- symbolic name such as "Usmarc", minus-1-terminated int
330 arrays and dotted strings such as "1.2.840.10003.9.5.1":
331 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
332 char *oid_to_dotstring(const int *oid, char *oidbuf);
333 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
335 Reverted modifications for ES Update definition for z_IU0Update
336 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
337 is back to YAZ 2.0.2.
339 String value attributes for CCL parser.
341 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
342 which their FirstSearch server returns in Init responses, sometimes
343 carrying useful diagnostic information when Init fails. This has the
344 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
345 "z39.50/oclcui.asn", where its definition is somewhat different from
346 what OCLC document on their web-site, as required to interoperate with
349 Support for anonymous authentication in yaz-client. Use the command
352 * Fix the OID of the Index Data-local "admin" Extended Service from
353 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
354 the 1000, which indicates a locally-defined OID, was a mistake.
358 Fix CCL directive @case handling so that it affects string match for
359 both CCL keywords and qualifiers.
361 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
362 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
363 Decoder has been updated with ASN.1 changes as listed in
364 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
365 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
366 z_IUUpdate, remains unchanged.
368 ZOOM_record_get may now return a record in a specific character set.
369 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
370 "from" is the character set of record as returned by target. "to" is
371 the character set to be returned. If omitted, "to" is UTF-8.
373 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
375 New ODR utility, odr_getelement, which returns name of element for
376 which encoding/decoding failed.
378 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
379 in cases where a required element was omitted.
381 Bug fix: some MARC8 sequences were not converted.
383 New ZOOM option "step" which specifies number of records to be
384 retrieved in one chunk. Used in conjunction with "start" and "count".
386 SRW support for yaz-client. Use scheme http: to use it, e.g.
389 yaz-client no longer does (un)intelligent character set conversions
390 by default. Can be enabled with charset and marc_charset commands.
392 xmalloc trace fix for 64-bit systems such as DEC alpha.
394 Solaris 2.6 compile fix.
396 New function, cql_strerror() translates SRW error codes, as returned
397 by cql_transform_error(), into human-readable English strings. Used
398 in yaz-client diagnostics when appropriate.
400 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
401 converts it into a type-1 query which is sent to the server. This
402 makes CQL available for use with all Z-servers, as opposed to the tiny
403 minority that can handle CQL queries themselves.
407 New Debian package layout similar to the Redhat Package layout.
409 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
410 and search result respectively.
414 Redhat package is now several packages: libyaz (runtime libraries),
415 libyaz-devel (development and documentation, and yaz (utility programs).
416 Package spec file by Morten Bøgeskov.
418 New member 'schema' in struct bend_fetch_rr which the name of requested
419 schema (SRW/SRU) for record (or NULL if none was given). The fetch
420 handler MAY set this to reflect the schema of the returned record.
422 New member 'display_term' in struct scan_entry. GFS now sets member entries
423 and allocates scan entries to be filled by user scan handler. In previous
424 version, entries member was allocated by the scan handler. That still works,
425 but the GFS will ignore member display_term - assuming it was NOT set by
426 the handler. The fact that the GFS now allocates the entries both allows
427 for new members and makes a scan handler easier to write.
429 Fix CQL lex buffer overflow.
431 SRW/SRU recordPacking. For SRW default recordPacking is string. For
432 SRU default recordPacking is string.
434 SRU protocol support for frontend server.
436 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
438 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
440 Added scan for the ZOOM shell (zoomsh).
444 * String Identifers for Schemas (Amendment 5).
445 http://lcweb.loc.gov/z3950/agency/amend/am5.html
446 Old definition for schema
447 Odr_oid *schema; /* OPT */
452 Z_InternationalString *uri;
453 #define Z_Schema_oid 1
454 #define Z_Schema_uri 2
457 * resultCount parameter to Sort Response (Amendment 1).
458 http://lcweb.loc.gov/z3950/agency/amend/am1.html
460 Support for SRW 1.0 over HTTP. This is an optional feature and
461 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
464 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
465 on the same port. SRW SearchRetrieveRequests are mapped
466 to bend_init,bend_search,bend_fetch,bend_close.
468 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
470 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
471 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
473 ZOOM connections are SRW based if schem http is used for hostname
474 in connect, e.g. z = ZOOM_connection_new("http://myserver");
475 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
477 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
478 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
479 distance=n, order=true/false, relation=le, prox unit=word. If
480 n is omitted, distance 1 is used.
482 Fixed problem with C compiler include path in wrong order.
484 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
485 on Solaris. Patch from Ko van der Sloot.
487 New MARC decode API. All new functions operate on a yaz_marc_t
488 handle. The most important new functions are: yaz_marc_create,
489 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
490 decode and destroy respectively. Decoder can produce formats
491 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
492 include/yaz/marcdisp.h.
494 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
495 to UTF-8, UCS-32, wchar_t or Latin-1.
497 * Prototypes for yaz_iconv_-functions moved to separate header
498 include/yaz/yaz-iconv.h.
500 Make a few private functions 'static' in unix.c. This prevents
501 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
503 For ZOOM connection, the options targetImplementation{Id,Name,Version}
504 are set when Init Response is received.
506 New function ZOOM_connection_error_x similar to ZOOM_connection_error
507 but returns diagnostic set as well.
509 New function yaz_strerror which is a portable wrapper for
510 strerror/strerror_r/GetLastMessage.
512 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
513 is returned for MARC. If type is "oai", then OAI MARC is returned.
515 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
520 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
522 Fix bad race conditions on SIGTERM and terminate gracefully in
525 Move retrieval (data1) module to Zebra since nobody seems to be
528 Add GRS-1 render for ZOOM using same format as yaz-client.
532 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
534 Fix broken ESpec handling in data1 module.
536 SGML reader parses comments and makes them part of the data1 tree.
538 Added several type casts so that YAZ compiles as C++ code.
540 ZOOM didn't handle PDU encoding failures properly.
542 Added more Bib-1 diagnostics (approved extensions).
544 GNU configure: better check for iconv.
546 More portable use of accept, getpeername. Check for socklen_t. Use
547 int/size_t if socklen_t is not defined.
551 PQF parser rejects bad queries - including those with extra
552 characters in them. PQF parser used to silently ignore that.
553 Cleaner API for PQF added, which allows you to get detailed
554 error information for bad queries (see yaz/pquery.h).
556 Fixed bug in ZOOM_record_get for type "database".
558 Implemented mini iconv library supporting conversions between
559 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
561 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
565 Fixed ZOOM C record cache so that preferredRecordSyntax and
566 elementSetName is used to check for already fetched records.
570 Added three members in bend_initrequest structure to facilitate
571 character set negotiation.
573 Fixed a bug in frontend server that could cause indefinite
574 loops under rare conditions.
576 Revised character set utilities (charneg.h) so that encoding
577 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
579 For PQF, directive @term <type> sets term type for Scan/Search.
580 Here <type> is general, string, numeric, null. The term type
581 is inherited - just like @attr.
583 New call odr_set_charset that sets character set conversion for
584 international-strings on a ODR stream. Prototype is:
585 int odr_set_charset(ODR o, const char *to, const char *from);
586 The InternationalString is still represented as C string in YAZ
587 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
588 won't). On the protocol level, you can use any encoding.
590 Support for UNIX sockets in ZOOM.
592 Solaris recv sometimes returns errno == ENOENT. It is treated as
593 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
595 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
596 both client and server. Code by Morten Bøgeskov.
600 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
601 that they can be used directly from Visual Basic. You must recompile
602 your windows APP if you're using ZOOM.
604 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
605 Commands "lang" and "charset" sets language and character set respectively.
606 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
607 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
609 Attributes from multiple CCL fields may be OR'ed rather than merged
610 using directive "@field or". Fields are still merged by default -
611 equivalent to "@field merge".
613 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
616 Fixed bug in zget for parameter ExtendedServicesResponse.
622 Added PQF feature: '@attr type=value' may be written as '@type=value'.
624 Client displays USR.1:SearchResult-1 (hits per term).
626 Additional Search Info for search in Generic Frontend Server.
628 Fixed CCL parsing of "field=s".
630 WIN32 installer - using the excellent NSIS software from nullsoft.
632 Fixed CCL parsing of "field = - <number>".
634 Added function yaz_marc_decode that decodes MARC for line mode
635 display or XML (similar to that used by JZKit).
637 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
638 Z39.50. But ISO/ILL was, however.
640 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
641 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
643 http://lcweb.loc.gov/z3950/agency/amend/am2.html
644 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
648 New YAZ client features: Command completion and new commands:
649 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
650 Code provided by Jacob Poulsen.
652 New call oid_trav, that visits all registered OIDs via callback.
654 Function ZOOM_record_get now returns const char pointer rather than
655 void pointer. It saves a lot of type casts.
657 For YAZ client, command "auth" now allows you to set authentication
658 in IdPass style. It is enabled when three tokens are given - order
659 is user, group and password.
661 Fix memory leaks in MARC record handling for ZOOM.
663 New option for YAZ client, -k <kilobytes> that sets
664 maximum record size. Similar to -k option for generic frontend
665 server and yaz-ztest.
667 More fixes for scan. Non-zero stepSize handled. OID's fixes.
669 Prefix query parser reports "fail" when bad attribute set is given.
671 Fix in MARC decoder. Proximity logging. Fix for attribute set
672 in scan handler for server. Patches by Shigeru Ishida.
674 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
677 Configure option --with-openssl=<dir> now works when a directory is
678 specified. Patch provided by Morten Bøgeskov.
680 New option for YAZ client, -u <auth>, that sets authentication.
682 ZOOM fix: error information was sometimes "missing", since error
683 was cleared/reset too when it shouldn't.
685 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
689 Scan for ZOOM API. New object ZOOM_scanset. New functions
690 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
691 ZOOM_scanset_destroy.
693 New ZOOM function, ZOOM_connection_last_event, that returns type
694 of last event (such as "receive data", "send data", "apdu received",
697 New ZOOM option, schema, that specifies schema for retrieval.
699 New CCL feature. Qualifiers can be aliases for one or more
700 other qualifiers (if more than one is given, OR is used).
702 ZOOM uses named result sets if target supports it.
704 Two new YAZ client commands: . (dot, which sources a script of YAZ
705 client commands), and ! (to execute shell command.). Implemented
708 Working on Debian packages.
712 YAZ client enables named result sets only if target supports it.
714 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
716 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
717 with key="host" to get same result.
719 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
720 Function Z3950_resultset_record(s) returns references to records
721 "owned" by resultset. To become owner use Z3950_record_clone.
723 Function z_ext_record handles Extended Services. Thanks to
728 CCL Parser fix: ignore token comma when dealing with and-lists.
730 Documentation updates for COMSTACK.
732 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
733 Changed prototype Z3950_records. For some functions, int parameters
734 were changed to size_t.
736 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
739 New MARC decode/display function, marc_display_exl, which properly rejects
740 non-ISO2709 records. YAZ client uses it.
744 Fix bug: local attribute set wasn't set correctly in PQF strings.
748 * Old Z39.50 codecs no longer supported.
750 Added ZOOM C binding. See http://zoom.z3950.org/
752 Renamed states for COMSTACKs to avoid confusion with events.
754 Implemented cs_look and proper cs_rcvconnect.
756 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
758 Configure detects POSIX threads on OpenBSD.
760 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
761 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
763 When error is returned from present handler, non-surrogate diagnostic
764 is returned in present response (and fetch handler is no longer called).
766 * Minor adjustments to pquery parser (PQF). Token characters may be
767 escaped by using backslash (C-style).
769 PQF parser allows string attribute values to be specified. For @attr,
770 non-numeric characters after the equal-sign are treated as strings
771 (e.g. @attr 9=title).
773 CCL trunction character may be defined (@truncation in file)
775 * function zget_ExtendedServicesRequest sets waitAction to
776 waitIfPossible (was wait).
778 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
781 CCL operator names may be set in field definition files (CCL_bibset).
782 See ccl/bib1 for an example.
784 Fixes in ASN.1 compiler for C++ compatibility.
786 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
787 and "op_or" to avoid conflict with C++.
789 Fixed problem with GNU readline detection on Redhat 7.0.
791 Added step-size for Scan backend handler.
793 Fixed bug that made the frontend server crash when no attribute
794 set was specified for scan.
796 Front-end server automatically switches to original working directory
797 when installed as an NT service. Previously -w had to be specified to
800 Added extended attributes for retrieval module (data1), so that data1
801 records carry d1_readXML/SGML attributes. d1_read also supports
802 null-data rules ( <tag/>)
804 On UNIX when POSIX threads are available, a separate library libyazthread
805 is created. Programmers should link with that library and the yaz library
806 when using threads. The reason for the split was that some applications
807 on Linux, such as Apache, doesn't work well when using shared objects that
810 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
811 (or any frontend server) in SSL mode by specifying ssl: followed by
812 address. Only tested on UNIX.
814 Added feature for CCL module. Virtual structure s=al or s=ol generates
815 and-list and or-list respectively instead of phrase search.
819 * Added prefix "yaz_" for the functions log_init.., log_file.. and
820 log_mask_str. This was done to avoid name conflicts with other libraries
821 (such as other PHP extensions).
823 Added raw OID member for preferred record syntax (request_format_raw)
824 and returned record syntax (output_format_raw) for backend fetch method.
826 Config file yaz-config now accepts options so that it returns specific
827 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
829 Shared library support for UNIX using GNU libtool.
831 * Modified backend interface. Request/Response struct's replaced by
832 one read/write C struct. For example bend_fetchrequest and
833 bend_fetchresult have been replaced by single bend_fetch_rr struct.
834 Every handler - even search has to be registered in bend_init
835 handler. This means that the YAZ library no longer refers to
836 external functions and it makes it possible to make the whole
837 thing a single DLL/SO.
839 Added Segment handler for backend server.
841 Added Zmbol/Zebra administrative functions to YAZ client.
843 Threaded frontend server on UNIX (when POSIX Threads are available).
844 Starting the server with option -T enables multi-threading.
848 Added configure option --enable-comp/disable-comp to control use
849 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
850 located in sub directory asn.
852 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
853 in ${exec_prefix}/bin along with the other programs yaz-client and
856 GNU automake used to maintain makefiles.
860 Changed retrieval module so that we can load records with no abstract
861 syntax defined. Tagpaths in these records are fully composed of string
864 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
868 On UNIX, the generated makefile now supports a proper 'make install'.
869 The prefix can be set via GNU configure to set the install location
870 (default is /usr/local).
872 * YAZ programs client and ztest were renamed to yaz-client and
873 yaz-ztest to avoid conflicts when users install YAZ in "standard"
874 locations, such as /usr/bin,/usr/local/bin,etc.
876 * YAZ Header files were moved from include to include/yaz. YAZ Header
877 files are referred to as include <yaz/log.h> rather than <log.h>.
878 The YAZ include path (-I ..) is therefore the same as before. Programmers
879 should update their #include statements or use -Ipath/include/yaz
880 instead. The main motivation for doing this change is that YAZ header files
881 can be installed in "standard" locations /usr/include,/usr/local/include
882 without introducing conflicts, since ALL YAZ header files are stored
883 in subdirectory yaz (under /usr/include for example).
885 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
886 rather than project/workspace files. We switched because project files
887 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
890 Changed name of logging function, logf, to yaz_log, to prevent name
891 clash with some math-log functions. The YAZ header log.h defines logf
892 to yaz_log (#define) so there should be no incompatibilities by this
895 Added bend_start/bend_stop handlers for server. These handler are
896 called on start/stop of server. For windows they are called whenever
897 a service is started/stopped.
899 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
900 a fairly small ASN.1 compiler written in Tcl. The compiler is located
901 in util/yc.tcl. The auto-generated C code structures are, in a few
902 cases, incompatible with the old decoders. There are differences in the
903 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
904 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
905 The preprocessor variable ASN_COMPILED is defined when the compiled
906 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
907 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
908 wish to use the old encoders/decoders you can specify --disable-yc
911 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
912 version so that it supports both new - and old version of DB Update
914 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
915 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
916 change. The name parameter can be set to 0 in which no name is specified
917 for the construction. The macros odr_implicit and odr_explicit sets name
918 parameter to zero for the construction involved. New macros
919 odr_implicit_tag and odr_explicit_tag are similar to the others,
920 except that a name parameter is added. For programmers' that don't use
921 ODR they probably only need to change the call to z_APDU and z_External.
923 Added access control facility by interfacing the TCP wrapper library.
924 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
925 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
926 name of the daemon and enables the access control as specified in
927 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
929 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
930 den Dool <H.M.vdnDool@kub.nl>.
932 Added reference ID parameter to most functions in server API - refer
933 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
935 Changed name of ccl library to libccl.a (was ccl.a).
937 Fixed bug in decoder for Explain (Category TargetInfo).
939 Added support for GNU readline in client. Thanks to Jacob Poulsen
940 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
942 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
943 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
944 IMPLEMENTATION! This change was made to the development version before
945 the ZIG decided to retract the amendment. If any users MUST be
946 compatible with the original Update definition, PLEASE CONTACT US, and
947 we will include a separate definition corresponding to the old Update
948 ES. Note that because of the change to the ASN.1 of the
949 TaskPackageRecordStructure we cannot define a single structure that
950 will support both versions.
952 * Added const modifier to buffer parameter for some ODR/BER encoding
953 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
954 completeWAIS, odr_dumpBER.
956 Fixed bug in client.c which caused a crash when a scanResponse didn't
957 contain positionOfTerm.
959 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
960 * will cause an error in a client if a non-YAZ target sends both a
961 * list of Scan entries and non-surrogate diagnostics.
963 Retrieval module enhancements. Tag sets may be typed in the reference
964 to it. From the .abs-file the "tagset" directive takes a third optional
965 integer type for the tag set referenced. From a .tag-file the "include"
966 directive takes a third optional type as well. The old "type" directive
967 in the tag set itself is still recognized but acts as the default type
970 Backend interface change. Individual Scan terms returned from bend_scan
971 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
972 in include/backend.h.
974 Retrieval module enhancements. Multiple tag sets and attribute sets may
975 be specified in abstract syntax specs. Revised the error/warning for
976 logging messages reported by the retrieval module when reading the
979 Object Identifier system (oid_..) changed. The API is backwards
980 compatible but the oid-routines now allocates new OID's when needed.
981 Raw OID's may be specified in oid_getvalbyname.
983 YAZ now uses GNU configure to generate Makefile(s).
985 * Minor changes in some of the member names of DeleteResultSetRequest and
986 DeleteResultSetResponse. See include/proto.h.
988 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
989 and added member 'languages' in TargetInfo (which was missing).
991 Changed the way attribute sets are handled in the retrieval
992 module. These are now cached, just like the abstract syntaxes
995 Changed YAZ so that it links with compiled ASN.1.
997 Added Explain-schema definitions and mapping routines. The following
998 Explain categories have been implemented: AttributeDetails,
999 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1001 Fixed minor bug in Windows version of Server Library.
1003 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1005 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1007 Added EXTERNAL: UNIverse Resource Report (non-standard).
1009 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1010 ENUMERATED and SET OF.
1012 * Added 'const' to some of the char pointer arguments for the
1013 functions, data1_read_node, data1_getelementbytagname,
1014 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1017 Fixed bug in data1_insert_taggeddata - the last_child member of
1018 parent wasn't initialised.
1020 * Changed data1_read_record and data1_read_node so that the supplied
1021 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1022 doesn't refer to any parts of the "SGML"-buffer.
1024 Fixed bug in server library (Windows version of statserv_remove).
1026 * Changed code so that it compiles as C++. The type definition
1027 of Odr_fun which is a member of Odr_arm was changed. The result is,
1028 that an explicit typecast is needed for the fun pointer when
1029 using Odr_arm - as in:
1030 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1032 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1034 Implemented the new structured date and time definition as approved
1035 by the ZIG. Added schemaId element to the specificTag in Espec-1
1036 (also approved at the last ZIG). Thanks to RVDM.
1038 Added some Object identifiers (RVDM).
1040 Changed the Update Extended Service (RVDM).
1042 Added command "refid" to client which specifies referenceId for
1043 the following requests.
1045 Implemented extended service handling for server. See ztest.c
1046 for an example as well as backend.h. New handlers are registerd
1047 in the Init handler.
1049 * Changed interface for sort in server.
1051 Added new members to statserv_options_block. It allows a server
1052 to read options from another source than just the command line. Thanks
1053 to Charles Woodfield.
1055 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1056 renamed to zboolean. Some C++ compilers complained about the name.
1058 Minor changes to gils.abs. Added index 's' (sort) on title
1059 and date/time-last-modified.
1061 --- 1.4pl2 1998/1/30
1063 Fixed bug in server library regarding inetd mode (-i). This bug
1064 was introduced by release 1.4.
1066 --- 1.4pl1 1998/1/29
1068 Added sort facility in client and backend server interface.
1070 Fixed problem with dependencies in Makefile(s).
1072 Fixed bugs for encoders/decoders of extended services and
1075 Implemented sub-tree feature for schemas. Sub-trees are
1076 referenced in *.abs-files. See explain.abs for an example
1077 of the use of this feature.
1079 Modified bib1.att; local attributes for ANY didn't include
1080 ANY itself (only affects use of the retrieval module).
1082 Fixed bug in plain SGML reader in function data1_read_node:
1083 tags with prefix "var" was incorrectly interpreted as variants.
1085 Added feature "sub-schemas" to enable references to - and definitions
1086 of - group of elements.
1088 * Removed member parent from type data1_element (in data1.h).
1090 Implemented function odr_nullval() that returns the value of
1093 * Removed member num_children from data1_node (in data1.h).
1095 Made NT service interface part of the server library. The
1096 function statserv_main uses the NT service when required and
1097 calls the statserv_start / statserv_close routines.
1099 Routine zget_SearchRequest and zget_PresentRequest fills
1100 resultSetName/Id member with "default" instead of "Default".
1102 Fixed memory leak in server. Request queue member wasn't freed.
1104 Fixed nmem_exit so that memory is freed.
1108 Revised the CCL parser utility to be thread safe.
1110 Added function, oid_ent_to_oid, to replace the function
1111 oid_getoidbyent, which is not thread safe.
1113 * Added nmem_init and nmem_exit to initialize and release
1114 NMEM resources. Function nmem_init should be called once in the
1115 initial thread before NMEM/ODR is used. statserv.c and client.c
1116 have been changed accordingly. The change was necessary to make
1117 NMEM thread safe. The NMEM memory pool is shared amongst threads
1118 in a process. Unix-based applications will still work fine without
1121 Added NT Services interface for the the Z39.50 (statserv) Server.
1122 Refer to the ztest.c source on the usage.
1124 Windows 95/NT port using MSVC5.0. Project files are included in the
1127 * Defined new 'global' handle for the retrieval (data1) system. The
1128 new handled, data1_handle, describes the state of the data1 system.
1129 This handle is passed as first argument to virtually all
1130 data1 related routines. The functions data1_create and data1_destroy
1131 creates and destroys a data1 handle respectively.
1133 Added ODR encode stream member to all backend request structures
1134 init, search, scan etc. This stream should be used to allocate all
1135 memory used for the response when thread safe operation is needed.
1137 Changed the comstack utility, cs_addstr, to be thread safe. The
1138 returned hostname string returned by the function is now part the
1141 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1142 function. The cs_straddr takes a COMSTACK handle as argument, so this
1143 function must be used after cs_create and before bind/connect.
1144 This function is thread safe.
1146 Moved test server to 'ztest' directory - generic server code still
1147 in 'server' directory.
1149 Made prefix query (pquery.c) utility thread safe.
1151 Added new function modifier YAZ_EXPORT to 'export' public DLL
1152 functions when using windows (see include/yconfig.h).
1154 Added definitions to the OID database (util/oid.c) (RVDM).
1156 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1158 Added call to ccl_rpn_delete in client program.
1160 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1161 release of RPN structure.
1163 Added support for C++, headers uses extern "C" for public definitions.
1164 With input from RVDM.
1166 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1167 Thanks to Ronald van der Meer (RVDM).
1169 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1171 Added support for private extensions to the OID database
1172 (oid_setprivateoids()). Thanks to RVDM.
1174 Added optional, physical ANY (key replication)
1176 Fixed null-reference problem in GRS-1 output filter.
1178 Proximity operator added to Prefix Query Format (PQF).
1180 In test client command "base" accepts multiple databases.
1182 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1186 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1188 Smallish bug-fixes in the new encoders/decoders (explain).
1190 Bug fixed in DeleteRequest.
1192 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1194 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1196 Added SOIF syntax (using private OID for now) to retrieval module and client.
1198 Added Update extended service.
1200 Added SearchResult-1 additional info structure.
1202 Added optional CCL (ISO8777) interpreter as separate module. Available
1205 --- 1.2 1996/6/10 (1st anniversary release)
1207 Added Summary record syntax. Lightly tested.
1209 Added OPAC record syntax. Untested.
1211 Added ResourceReport service encoders/decoders. Untested.
1213 Fixed bug in z_Unit - wrong tagging on unitSystem.
1215 Fixed bug in the DiagRecs decoder.
1217 Added options for max PDU size and session timeout to frontend-server.
1219 Added documentation of query-language parsers and other supporting utilities.
1221 [frontend-server] Added Attribute set to the bend_scanrequest API.
1223 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1224 surrogate diagnostics were generated.
1226 [retrieval] Allow multiple local values for attribute.
1228 [retrieval] Allow multiple attributes per element in .abs files. index type.
1230 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1232 --- 1.1pl2 1996/4/10
1234 Minor changes, mostly specific to Zebra's requirements (retrieval)
1238 Repaired bug in frontend server when running multiple listening
1239 endpoints in dynamic mode.
1241 z_External() now won't break if a known, ASN.1 value comes encapsulated
1242 in an octet-string. The value will pass through unmodified in an Odr_oct.
1244 Added a bit of code to the demo client to decode & display
1245 ASN.1-structured records represented in the octet-aligned branch of
1246 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1248 Added z_ext_getentbyref() to the ASN module. Doc updated.
1250 * Completed the SCAN definition in the ASN module. This may break SCAN
1251 code based on older YAZ-versions at compile-time. The fix is easy -
1254 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1255 under the SCAN definition. Remember to initialize this, server-people.
1257 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1258 that this does not extend to ODR and ASN.
1260 Comstack allows insertion of established socket (primarily for
1261 inetd-operation of servers). Doc updated.
1263 Front-end server can now start from the inetd in TCP mode. Doc
1266 --- 1.0pl4 1996/1/24
1270 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1271 the rank and record number.
1273 Adjustments to the frontend server.
1275 Fixed diagnostic BER dumper. It ignored the file argument.
1279 Various changes to retrieval module.
1281 Changed the union discriminators of the protocol files from enums to
1282 ints paired with #defines.
1284 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1287 *Changed operator in the RPN structure to 'roperator', again to avoid a
1290 Fixed problems in Explain decoders/encoders.
1292 --- 1.0pl2 1995/12/6
1294 Memory bug in log module fixed.
1296 --- 1.0pl1 1995/12/5
1298 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1300 Bug in Explain DatabaseInfo module fixed.
1302 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1306 The shift to v1.0 signals that we now consider the *core* functionality
1307 of YAZ reasonably stable (the core being more or less equivalent to
1308 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1309 tested (Explain not at all - though that will happen soonish).
1311 Minor changes to code to support Windows port.
1313 Various minor changes after we're getting to use GRS-1 & co. more.
1315 Added Espec-1 format.
1317 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1318 of the protocol and it cannot be selected when encoding (maps into 'string'
1319 when decoding). Needed to talk to some servers.
1321 Demo client can request simple element set names.
1323 Added Diagnostic Format encoders/decoders.
1325 Added simple Close handling to frontend server (no hooks for resource
1326 reporting yet), and demonstration client.
1328 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1330 --- 1.0b3 1995/08/24
1332 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1333 handled incorrectly when records were requested in the searchResponse. This
1334 will only affect you if you use the frontend-server.
1336 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1337 Test-client will ask for and print GRS1. Ztest will return dummy records
1340 Added Explain encoders/decoders to the service-level API. Untested.
1342 Added Extended Services: Item Order encoders and decoders to the Service-
1343 level API. Untested. We could use a recent copy of the pertinent bits
1344 of the ILL protocol to add those bits.
1346 Added diagnostic format 1 encoders/decoders to the service-level API.
1349 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1350 odr_cons.c, which causes a more correct output.
1352 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1353 was always set to 0 when no records were requested in the searchRequest.
1355 * Added better external-handling. This shouldn't harm old code that
1356 *encodes* externals. It can break code that looks for a
1357 'single-ASN1-type' representation, since those types that are known
1358 are now decoded immediately. Look at the SUTRS sample code in
1359 seshigh.c and client.c. Documentation updated.
1361 Handling of structured records in bend_fetchresponse. Length -1 marks
1362 structured record, type is deduced from format field.
1364 --- 1.0b2 1995/06/27
1365 Fairly quick maintenance release to add SUTRS support.
1367 Fixed handling of SUTRS records in the demonstration client.
1369 * Added format field to the bend_fetchrequest and bend_fetchresponce
1370 structures of the backend API (frontend server). When the record is
1371 returned, the value of the format field is mapped to an OID. The
1372 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1373 of the record. The special value VAL_NONE in the bend_request means
1374 that no specific format was requested by the client. Documentation
1375 updated accordingly. Test server (ztest) will return a fixed dummy
1376 SUTRS record if your client requests SUTRS.
1378 Documentation updated accordingly.
1380 You can now set external libraries and RANLIB support in the top-level
1384 First public release.
