1 Possible compatibility problems with earlier versions marked with '*'.
3 --- 2.0.9-5 2004/01/07 Debian/Windows
5 Handle user defined stylesheet for SRW/SRU.
7 --- 2.0.9-4 2004/01/06 Debian/Windows
9 Fix bug in decoding of Content-Length.
11 --- 2.0.9-3 2004/01/06 Debian/Windows
13 Fix a bug with decoding of XML packed records.
15 --- 2.0.9-2 2004/01/05 Debian only
17 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
19 Fix bug in SRW/SRU diagnostics decoding.
23 Fixed bug in Generic Frontend Server which could drop records exceeding
24 preferred message size. Reported and fixed by Irina Dijour.
26 Fixed calculation of package size for structured records in Generic
27 Frontend Server. Reported and fixed by Irina Dijour.
29 Fixed namespace for SRW/SRU diagnostics.
31 Fixed SEGV in yaz-client that occured for HTTP connection errors.
35 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
36 this version is incompatible with version 1.0 and older YAZ SRW/SRU
39 CQL changes to reflect recent changes to the specification:
40 * Documentation talks about context sets instead of index sets.
41 * Documentation talks about indexes instead of qualifiers.
42 * The CQL-to-PQF transformer's configuration file now uses
43 "index.set.name = <attributes>" instead of the old form
44 "qualifier.set.name = <attributes>". (Both forms are still
45 understood but the latter is deprecated.)
46 * CQL terms with no explicit index specified are now interpreted as
47 cql.serverChoice instead of srw.serverChoice (which of course
48 behaves exactly the same.)
52 MARC conversion can now generate ISO2709 output in another
53 character set. yaz-marcdump uses this facility if you invoke it
56 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
57 functions from there can be used from C++.
61 Frontend server now transfers memory from decoded packages to stream
64 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
65 references to show up.
67 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
68 the ZOOM Abstract API. The older names for the same options are still
69 also supported for the benefit of old applications.
71 ZOOM-C supports "implementationId" and "implementationVersion" options
72 to go along with "implementationName". These allow the user code to
73 specify identification strings to be sent to servers.
74 Add OID for the new ExtLite attribute set.
76 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
77 as requested/supplid by Ere Maijala <ere@atp.fi>
79 For generic frontend server, reverse the order of
80 "toolkit-supplied / application-supplied" strings sent as implementationId,
81 Name and Version. Also, remove the spaces around the slash. This brings
82 the GFS in line with the behaviour of ZOOM-C on the client side.
84 Add function ZOOM_scanset_display_term.
86 yaz-client shows scan displayTerm if present.
88 Utility yaz-iconv is now installed by default along with the man page
91 Extend configure check for OpenSSL to use pkg-config where available (such
94 Incorporate patch by Morten Bogeskov which allows a Unix file socket
95 server to specify uid/gid/mask for socket using the format
96 unix:[user=uid,][group=gid,][umask=mask,]file=path
97 If file= is omitted the existing format is assumed, e.g.
99 in which case the mask is 0666 (rw for everybody).
101 Major restructure of YAZ source. All source in libyaz is in src directory.
102 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
103 util (utility programs such as ASN.1 compiler, yaz-marcdump).
105 Added man page for utility yaz-marcdump (used to be called marcdump).
106 yaz-marcdump is installed by 'make install'.
108 Fixed a memory leak in Generic Frontend Server that occurred when decoding
109 of incoming package failed.
111 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
113 Change prototype of odr_perror: add const to message string.
115 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
117 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
118 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
119 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
120 DNS lookup. There should not be any compatibility problems with this
121 assuming that blocking=1 or 0 is used.
123 Fix bad reference in UNIX comstack in function cs_addrstr.
125 Fix for compilation on AIX.
127 The generic front-end server (server/seshigh.c) now supports returning
128 Init diagnostics to the client in User-information-field, in
129 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
134 Allow any CQL relation (not just all,any,exact,scr).
136 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
137 that features the same UI.
139 Implemented command update0 in YAZ client which is equivalent to
140 update but uses old of Ext Update ASN.1.
142 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
143 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
144 Previously no OID was used for this info.
146 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
147 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
148 returns 'malformed search term' otherwise.
150 SortResponse member resultCount now set to NULL in sort handler of
153 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
156 Add three new utility functions for translating OIDs between various
157 formats -- symbolic name such as "Usmarc", minus-1-terminated int
158 arrays and dotted strings such as "1.2.840.10003.9.5.1":
159 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
160 char *oid_to_dotstring(const int *oid, char *oidbuf);
161 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
163 Reverted modifications for ES Update definition for z_IU0Update
164 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
165 is back to YAZ 2.0.2.
167 String value attributes for CCL parser.
169 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
170 which their FirstSearch server returns in Init responses, sometimes
171 carrying useful diagnostic information when Init fails. This has the
172 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
173 "z39.50/oclcui.asn", where its definition is somewhat different from
174 what OCLC document on their web-site, as required to interoperate with
177 Support for anonymous authentication in yaz-client. Use the command
180 * Fix the OID of the Index Data-local "admin" Extended Service from
181 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
182 the 1000, which indicates a locally-defined OID, was a mistake.
186 Fix CCL directive @case handling so that it affects string match for
187 both CCL keywords and qualifiers.
189 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
190 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
191 Decoder has been updated with ASN.1 changes as listed in
192 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
193 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
194 z_IUUpdate, remains unchanged.
196 ZOOM_record_get may now return a record in a specific character set.
197 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
198 "from" is the character set of record as returned by target. "to" is
199 the character set to be returned. If omitted, "to" is UTF-8.
201 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
203 New ODR utility, odr_getelement, which returns name of element for
204 which encoding/decoding failed.
206 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
207 in cases where a required element was omitted.
209 Bug fix: some MARC8 sequences were not converted.
211 New ZOOM option "step" which specifies number of records to be
212 retrieved in one chunk. Used in conjunction with "start" and "count".
214 SRW support for yaz-client. Use scheme http: to use it, e.g.
217 yaz-client no longer does (un)intelligent character set conversions
218 by default. Can be enabled with charset and marc_charset commands.
220 xmalloc trace fix for 64-bit systems such as DEC alpha.
222 Solaris 2.6 compile fix.
224 New function, cql_strerror() translates SRW error codes, as returned
225 by cql_transform_error(), into human-readable English strings. Used
226 in yaz-client diagnostics when appropriate.
228 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
229 converts it into a type-1 query which is sent to the server. This
230 makes CQL available for use with all Z-servers, as opposed to the tiny
231 minority that can handle CQL queries themselves.
235 New Debian package layout similar to the Redhat Package layout.
237 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
238 and search result respectively.
242 Redhat package is now several packages: libyaz (runtime libraries),
243 libyaz-devel (development and documentation, and yaz (utility programs).
244 Package spec file by Morten Bøgeskov.
246 New member 'schema' in struct bend_fetch_rr which the name of requested
247 schema (SRW/SRU) for record (or NULL if none was given). The fetch
248 handler MAY set this to reflect the schema of the returned record.
250 New member 'display_term' in struct scan_entry. GFS now sets member entries
251 and allocates scan entries to be filled by user scan handler. In previous
252 version, entries member was allocated by the scan handler. That still works,
253 but the GFS will ignore member display_term - assuming it was NOT set by
254 the handler. The fact that the GFS now allocates the entries both allows
255 for new members and makes a scan handler easier to write.
257 Fix CQL lex buffer overflow.
259 SRW/SRU recordPacking. For SRW default recordPacking is string. For
260 SRU default recordPacking is string.
262 SRU protocol support for frontend server.
264 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
266 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
268 Added scan for the ZOOM shell (zoomsh).
272 * String Identifers for Schemas (Amendment 5).
273 http://lcweb.loc.gov/z3950/agency/amend/am5.html
274 Old definition for schema
275 Odr_oid *schema; /* OPT */
280 Z_InternationalString *uri;
281 #define Z_Schema_oid 1
282 #define Z_Schema_uri 2
285 * resultCount parameter to Sort Response (Amendment 1).
286 http://lcweb.loc.gov/z3950/agency/amend/am1.html
288 Support for SRW 1.0 over HTTP. This is an optional feature and
289 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
292 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
293 on the same port. SRW SearchRetrieveRequests are mapped
294 to bend_init,bend_search,bend_fetch,bend_close.
296 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
298 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
299 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
301 ZOOM connections are SRW based if schem http is used for hostname
302 in connect, e.g. z = ZOOM_connection_new("http://myserver");
303 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
305 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
306 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
307 distance=n, order=true/false, relation=le, prox unit=word. If
308 n is omitted, distance 1 is used.
310 Fixed problem with C compiler include path in wrong order.
312 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
313 on Solaris. Patch from Ko van der Sloot.
315 New MARC decode API. All new functions operate on a yaz_marc_t
316 handle. The most important new functions are: yaz_marc_create,
317 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
318 decode and destroy respectively. Decoder can produce formats
319 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
320 include/yaz/marcdisp.h.
322 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
323 to UTF-8, UCS-32, wchar_t or Latin-1.
325 * Prototypes for yaz_iconv_-functions moved to separate header
326 include/yaz/yaz-iconv.h.
328 Make a few private functions 'static' in unix.c. This prevents
329 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
331 For ZOOM connection, the options targetImplementation{Id,Name,Version}
332 are set when Init Response is received.
334 New function ZOOM_connection_error_x similar to ZOOM_connection_error
335 but returns diagnostic set as well.
337 New function yaz_strerror which is a portable wrapper for
338 strerror/strerror_r/GetLastMessage.
340 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
341 is returned for MARC. If type is "oai", then OAI MARC is returned.
343 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
348 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
350 Fix bad race conditions on SIGTERM and terminate gracefully in
353 Move retrieval (data1) module to Zebra since nobody seems to be
356 Add GRS-1 render for ZOOM using same format as yaz-client.
360 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
362 Fix broken ESpec handling in data1 module.
364 SGML reader parses comments and makes them part of the data1 tree.
366 Added several type casts so that YAZ compiles as C++ code.
368 ZOOM didn't handle PDU encoding failures properly.
370 Added more Bib-1 diagnostics (approved extensions).
372 GNU configure: better check for iconv.
374 More portable use of accept, getpeername. Check for socklen_t. Use
375 int/size_t if socklen_t is not defined.
379 PQF parser rejects bad queries - including those with extra
380 characters in them. PQF parser used to silently ignore that.
381 Cleaner API for PQF added, which allows you to get detailed
382 error information for bad queries (see yaz/pquery.h).
384 Fixed bug in ZOOM_record_get for type "database".
386 Implemented mini iconv library supporting conversions between
387 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
389 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
393 Fixed ZOOM C record cache so that preferredRecordSyntax and
394 elementSetName is used to check for already fetched records.
398 Added three members in bend_initrequest structure to facilitate
399 character set negotiation.
401 Fixed a bug in frontend server that could cause indefinite
402 loops under rare conditions.
404 Revised character set utilities (charneg.h) so that encoding
405 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
407 For PQF, directive @term <type> sets term type for Scan/Search.
408 Here <type> is general, string, numeric, null. The term type
409 is inherited - just like @attr.
411 New call odr_set_charset that sets character set conversion for
412 international-strings on a ODR stream. Prototype is:
413 int odr_set_charset(ODR o, const char *to, const char *from);
414 The InternationalString is still represented as C string in YAZ
415 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
416 won't). On the protocol level, you can use any encoding.
418 Support for UNIX sockets in ZOOM.
420 Solaris recv sometimes returns errno == ENOENT. It is treated as
421 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
423 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
424 both client and server. Code by Morten Bøgeskov.
428 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
429 that they can be used directly from Visual Basic. You must recompile
430 your windows APP if you're using ZOOM.
432 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
433 Commands "lang" and "charset" sets language and character set respectively.
434 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
435 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
437 Attributes from multiple CCL fields may be OR'ed rather than merged
438 using directive "@field or". Fields are still merged by default -
439 equivalent to "@field merge".
441 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
444 Fixed bug in zget for parameter ExtendedServicesResponse.
450 Added PQF feature: '@attr type=value' may be written as '@type=value'.
452 Client displays USR.1:SearchResult-1 (hits per term).
454 Additional Search Info for search in Generic Frontend Server.
456 Fixed CCL parsing of "field=s".
458 WIN32 installer - using the excellent NSIS software from nullsoft.
460 Fixed CCL parsing of "field = - <number>".
462 Added function yaz_marc_decode that decodes MARC for line mode
463 display or XML (similar to that used by JZKit).
465 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
466 Z39.50. But ISO/ILL was, however.
468 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
469 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
471 http://lcweb.loc.gov/z3950/agency/amend/am2.html
472 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
476 New YAZ client features: Command completion and new commands:
477 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
478 Code provided by Jacob Poulsen.
480 New call oid_trav, that visits all registered OIDs via callback.
482 Function ZOOM_record_get now returns const char pointer rather than
483 void pointer. It saves a lot of type casts.
485 For YAZ client, command "auth" now allows you to set authentication
486 in IdPass style. It is enabled when three tokens are given - order
487 is user, group and password.
489 Fix memory leaks in MARC record handling for ZOOM.
491 New option for YAZ client, -k <kilobytes> that sets
492 maximum record size. Similar to -k option for generic frontend
493 server and yaz-ztest.
495 More fixes for scan. Non-zero stepSize handled. OID's fixes.
497 Prefix query parser reports "fail" when bad attribute set is given.
499 Fix in MARC decoder. Proximity logging. Fix for attribute set
500 in scan handler for server. Patches by Shigeru Ishida.
502 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
505 Configure option --with-openssl=<dir> now works when a directory is
506 specified. Patch provided by Morten Bøgeskov.
508 New option for YAZ client, -u <auth>, that sets authentication.
510 ZOOM fix: error information was sometimes "missing", since error
511 was cleared/reset too when it shouldn't.
513 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
517 Scan for ZOOM API. New object ZOOM_scanset. New functions
518 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
519 ZOOM_scanset_destroy.
521 New ZOOM function, ZOOM_connection_last_event, that returns type
522 of last event (such as "receive data", "send data", "apdu received",
525 New ZOOM option, schema, that specifies schema for retrieval.
527 New CCL feature. Qualifiers can be aliases for one or more
528 other qualifiers (if more than one is given, OR is used).
530 ZOOM uses named result sets if target supports it.
532 Two new YAZ client commands: . (dot, which sources a script of YAZ
533 client commands), and ! (to execute shell command.). Implemented
536 Working on Debian packages.
540 YAZ client enables named result sets only if target supports it.
542 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
544 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
545 with key="host" to get same result.
547 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
548 Function Z3950_resultset_record(s) returns references to records
549 "owned" by resultset. To become owner use Z3950_record_clone.
551 Function z_ext_record handles Extended Services. Thanks to
556 CCL Parser fix: ignore token comma when dealing with and-lists.
558 Documentation updates for COMSTACK.
560 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
561 Changed prototype Z3950_records. For some functions, int parameters
562 were changed to size_t.
564 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
567 New MARC decode/display function, marc_display_exl, which properly rejects
568 non-ISO2709 records. YAZ client uses it.
572 Fix bug: local attribute set wasn't set correctly in PQF strings.
576 * Old Z39.50 codecs no longer supported.
578 Added ZOOM C binding. See http://zoom.z3950.org/
580 Renamed states for COMSTACKs to avoid confusion with events.
582 Implemented cs_look and proper cs_rcvconnect.
584 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
586 Configure detects POSIX threads on OpenBSD.
588 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
589 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
591 When error is returned from present handler, non-surrogate diagnostic
592 is returned in present response (and fetch handler is no longer called).
594 * Minor adjustments to pquery parser (PQF). Token characters may be
595 escaped by using backslash (C-style).
597 PQF parser allows string attribute values to be specified. For @attr,
598 non-numeric characters after the equal-sign are treated as strings
599 (e.g. @attr 9=title).
601 CCL trunction character may be defined (@truncation in file)
603 * function zget_ExtendedServicesRequest sets waitAction to
604 waitIfPossible (was wait).
606 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
609 CCL operator names may be set in field definition files (CCL_bibset).
610 See ccl/bib1 for an example.
612 Fixes in ASN.1 compiler for C++ compatibility.
614 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
615 and "op_or" to avoid conflict with C++.
617 Fixed problem with GNU readline detection on Redhat 7.0.
619 Added step-size for Scan backend handler.
621 Fixed bug that made the frontend server crash when no attribute
622 set was specified for scan.
624 Front-end server automatically switches to original working directory
625 when installed as an NT service. Previously -w had to be specified to
628 Added extended attributes for retrieval module (data1), so that data1
629 records carry d1_readXML/SGML attributes. d1_read also supports
630 null-data rules ( <tag/>)
632 On UNIX when POSIX threads are available, a separate library libyazthread
633 is created. Programmers should link with that library and the yaz library
634 when using threads. The reason for the split was that some applications
635 on Linux, such as Apache, doesn't work well when using shared objects that
638 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
639 (or any frontend server) in SSL mode by specifying ssl: followed by
640 address. Only tested on UNIX.
642 Added feature for CCL module. Virtual structure s=al or s=ol generates
643 and-list and or-list respectively instead of phrase search.
647 * Added prefix "yaz_" for the functions log_init.., log_file.. and
648 log_mask_str. This was done to avoid name conflicts with other libraries
649 (such as other PHP extensions).
651 Added raw OID member for preferred record syntax (request_format_raw)
652 and returned record syntax (output_format_raw) for backend fetch method.
654 Config file yaz-config now accepts options so that it returns specific
655 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
657 Shared library support for UNIX using GNU libtool.
659 * Modified backend interface. Request/Response struct's replaced by
660 one read/write C struct. For example bend_fetchrequest and
661 bend_fetchresult have been replaced by single bend_fetch_rr struct.
662 Every handler - even search has to be registered in bend_init
663 handler. This means that the YAZ library no longer refers to
664 external functions and it makes it possible to make the whole
665 thing a single DLL/SO.
667 Added Segment handler for backend server.
669 Added Zmbol/Zebra administrative functions to YAZ client.
671 Threaded frontend server on UNIX (when POSIX Threads are available).
672 Starting the server with option -T enables multi-threading.
676 Added configure option --enable-comp/disable-comp to control use
677 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
678 located in sub directory asn.
680 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
681 in ${exec_prefix}/bin along with the other programs yaz-client and
684 GNU automake used to maintain makefiles.
688 Changed retrieval module so that we can load records with no abstract
689 syntax defined. Tagpaths in these records are fully composed of string
692 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
696 On UNIX, the generated makefile now supports a proper 'make install'.
697 The prefix can be set via GNU configure to set the install location
698 (default is /usr/local).
700 * YAZ programs client and ztest were renamed to yaz-client and
701 yaz-ztest to avoid conflicts when users install YAZ in "standard"
702 locations, such as /usr/bin,/usr/local/bin,etc.
704 * YAZ Header files were moved from include to include/yaz. YAZ Header
705 files are referred to as include <yaz/log.h> rather than <log.h>.
706 The YAZ include path (-I ..) is therefore the same as before. Programmers
707 should update their #include statements or use -Ipath/include/yaz
708 instead. The main motivation for doing this change is that YAZ header files
709 can be installed in "standard" locations /usr/include,/usr/local/include
710 without introducing conflicts, since ALL YAZ header files are stored
711 in subdirectory yaz (under /usr/include for example).
713 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
714 rather than project/workspace files. We switched because project files
715 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
718 Changed name of logging function, logf, to yaz_log, to prevent name
719 clash with some math-log functions. The YAZ header log.h defines logf
720 to yaz_log (#define) so there should be no incompatibilities by this
723 Added bend_start/bend_stop handlers for server. These handler are
724 called on start/stop of server. For windows they are called whenever
725 a service is started/stopped.
727 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
728 a fairly small ASN.1 compiler written in Tcl. The compiler is located
729 in util/yc.tcl. The auto-generated C code structures are, in a few
730 cases, incompatible with the old decoders. There are differences in the
731 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
732 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
733 The preprocessor variable ASN_COMPILED is defined when the compiled
734 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
735 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
736 wish to use the old encoders/decoders you can specify --disable-yc
739 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
740 version so that it supports both new - and old version of DB Update
742 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
743 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
744 change. The name parameter can be set to 0 in which no name is specified
745 for the construction. The macros odr_implicit and odr_explicit sets name
746 parameter to zero for the construction involved. New macros
747 odr_implicit_tag and odr_explicit_tag are similar to the others,
748 except that a name parameter is added. For programmers' that don't use
749 ODR they probably only need to change the call to z_APDU and z_External.
751 Added access control facility by interfacing the TCP wrapper library.
752 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
753 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
754 name of the daemon and enables the access control as specified in
755 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
757 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
758 den Dool <H.M.vdnDool@kub.nl>.
760 Added reference ID parameter to most functions in server API - refer
761 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
763 Changed name of ccl library to libccl.a (was ccl.a).
765 Fixed bug in decoder for Explain (Category TargetInfo).
767 Added support for GNU readline in client. Thanks to Jacob Poulsen
768 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
770 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
771 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
772 IMPLEMENTATION! This change was made to the development version before
773 the ZIG decided to retract the amendment. If any users MUST be
774 compatible with the original Update definition, PLEASE CONTACT US, and
775 we will include a separate definition corresponding to the old Update
776 ES. Note that because of the change to the ASN.1 of the
777 TaskPackageRecordStructure we cannot define a single structure that
778 will support both versions.
780 * Added const modifier to buffer parameter for some ODR/BER encoding
781 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
782 completeWAIS, odr_dumpBER.
784 Fixed bug in client.c which caused a crash when a scanResponse didn't
785 contain positionOfTerm.
787 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
788 * will cause an error in a client if a non-YAZ target sends both a
789 * list of Scan entries and non-surrogate diagnostics.
791 Retrieval module enhancements. Tag sets may be typed in the reference
792 to it. From the .abs-file the "tagset" directive takes a third optional
793 integer type for the tag set referenced. From a .tag-file the "include"
794 directive takes a third optional type as well. The old "type" directive
795 in the tag set itself is still recognized but acts as the default type
798 Backend interface change. Individual Scan terms returned from bend_scan
799 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
800 in include/backend.h.
802 Retrieval module enhancements. Multiple tag sets and attribute sets may
803 be specified in abstract syntax specs. Revised the error/warning for
804 logging messages reported by the retrieval module when reading the
807 Object Identifier system (oid_..) changed. The API is backwards
808 compatible but the oid-routines now allocates new OID's when needed.
809 Raw OID's may be specified in oid_getvalbyname.
811 YAZ now uses GNU configure to generate Makefile(s).
813 * Minor changes in some of the member names of DeleteResultSetRequest and
814 DeleteResultSetResponse. See include/proto.h.
816 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
817 and added member 'languages' in TargetInfo (which was missing).
819 Changed the way attribute sets are handled in the retrieval
820 module. These are now cached, just like the abstract syntaxes
823 Changed YAZ so that it links with compiled ASN.1.
825 Added Explain-schema definitions and mapping routines. The following
826 Explain categories have been implemented: AttributeDetails,
827 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
829 Fixed minor bug in Windows version of Server Library.
831 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
833 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
835 Added EXTERNAL: UNIverse Resource Report (non-standard).
837 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
838 ENUMERATED and SET OF.
840 * Added 'const' to some of the char pointer arguments for the
841 functions, data1_read_node, data1_getelementbytagname,
842 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
845 Fixed bug in data1_insert_taggeddata - the last_child member of
846 parent wasn't initialised.
848 * Changed data1_read_record and data1_read_node so that the supplied
849 "SGML"-buffer is read-only. In particular the resulting data1 - tree
850 doesn't refer to any parts of the "SGML"-buffer.
852 Fixed bug in server library (Windows version of statserv_remove).
854 * Changed code so that it compiles as C++. The type definition
855 of Odr_fun which is a member of Odr_arm was changed. The result is,
856 that an explicit typecast is needed for the fun pointer when
857 using Odr_arm - as in:
858 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
860 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
862 Implemented the new structured date and time definition as approved
863 by the ZIG. Added schemaId element to the specificTag in Espec-1
864 (also approved at the last ZIG). Thanks to RVDM.
866 Added some Object identifiers (RVDM).
868 Changed the Update Extended Service (RVDM).
870 Added command "refid" to client which specifies referenceId for
871 the following requests.
873 Implemented extended service handling for server. See ztest.c
874 for an example as well as backend.h. New handlers are registerd
877 * Changed interface for sort in server.
879 Added new members to statserv_options_block. It allows a server
880 to read options from another source than just the command line. Thanks
881 to Charles Woodfield.
883 * Changed definition of Z_Triple in file prt-grs.h - member boolean
884 renamed to zboolean. Some C++ compilers complained about the name.
886 Minor changes to gils.abs. Added index 's' (sort) on title
887 and date/time-last-modified.
891 Fixed bug in server library regarding inetd mode (-i). This bug
892 was introduced by release 1.4.
896 Added sort facility in client and backend server interface.
898 Fixed problem with dependencies in Makefile(s).
900 Fixed bugs for encoders/decoders of extended services and
903 Implemented sub-tree feature for schemas. Sub-trees are
904 referenced in *.abs-files. See explain.abs for an example
905 of the use of this feature.
907 Modified bib1.att; local attributes for ANY didn't include
908 ANY itself (only affects use of the retrieval module).
910 Fixed bug in plain SGML reader in function data1_read_node:
911 tags with prefix "var" was incorrectly interpreted as variants.
913 Added feature "sub-schemas" to enable references to - and definitions
914 of - group of elements.
916 * Removed member parent from type data1_element (in data1.h).
918 Implemented function odr_nullval() that returns the value of
921 * Removed member num_children from data1_node (in data1.h).
923 Made NT service interface part of the server library. The
924 function statserv_main uses the NT service when required and
925 calls the statserv_start / statserv_close routines.
927 Routine zget_SearchRequest and zget_PresentRequest fills
928 resultSetName/Id member with "default" instead of "Default".
930 Fixed memory leak in server. Request queue member wasn't freed.
932 Fixed nmem_exit so that memory is freed.
936 Revised the CCL parser utility to be thread safe.
938 Added function, oid_ent_to_oid, to replace the function
939 oid_getoidbyent, which is not thread safe.
941 * Added nmem_init and nmem_exit to initialize and release
942 NMEM resources. Function nmem_init should be called once in the
943 initial thread before NMEM/ODR is used. statserv.c and client.c
944 have been changed accordingly. The change was necessary to make
945 NMEM thread safe. The NMEM memory pool is shared amongst threads
946 in a process. Unix-based applications will still work fine without
949 Added NT Services interface for the the Z39.50 (statserv) Server.
950 Refer to the ztest.c source on the usage.
952 Windows 95/NT port using MSVC5.0. Project files are included in the
955 * Defined new 'global' handle for the retrieval (data1) system. The
956 new handled, data1_handle, describes the state of the data1 system.
957 This handle is passed as first argument to virtually all
958 data1 related routines. The functions data1_create and data1_destroy
959 creates and destroys a data1 handle respectively.
961 Added ODR encode stream member to all backend request structures
962 init, search, scan etc. This stream should be used to allocate all
963 memory used for the response when thread safe operation is needed.
965 Changed the comstack utility, cs_addstr, to be thread safe. The
966 returned hostname string returned by the function is now part the
969 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
970 function. The cs_straddr takes a COMSTACK handle as argument, so this
971 function must be used after cs_create and before bind/connect.
972 This function is thread safe.
974 Moved test server to 'ztest' directory - generic server code still
975 in 'server' directory.
977 Made prefix query (pquery.c) utility thread safe.
979 Added new function modifier YAZ_EXPORT to 'export' public DLL
980 functions when using windows (see include/yconfig.h).
982 Added definitions to the OID database (util/oid.c) (RVDM).
984 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
986 Added call to ccl_rpn_delete in client program.
988 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
989 release of RPN structure.
991 Added support for C++, headers uses extern "C" for public definitions.
992 With input from RVDM.
994 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
995 Thanks to Ronald van der Meer (RVDM).
997 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
999 Added support for private extensions to the OID database
1000 (oid_setprivateoids()). Thanks to RVDM.
1002 Added optional, physical ANY (key replication)
1004 Fixed null-reference problem in GRS-1 output filter.
1006 Proximity operator added to Prefix Query Format (PQF).
1008 In test client command "base" accepts multiple databases.
1010 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1014 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1016 Smallish bug-fixes in the new encoders/decoders (explain).
1018 Bug fixed in DeleteRequest.
1020 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1022 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1024 Added SOIF syntax (using private OID for now) to retrieval module and client.
1026 Added Update extended service.
1028 Added SearchResult-1 additional info structure.
1030 Added optional CCL (ISO8777) interpreter as separate module. Available
1033 --- 1.2 1996/6/10 (1st anniversary release)
1035 Added Summary record syntax. Lightly tested.
1037 Added OPAC record syntax. Untested.
1039 Added ResourceReport service encoders/decoders. Untested.
1041 Fixed bug in z_Unit - wrong tagging on unitSystem.
1043 Fixed bug in the DiagRecs decoder.
1045 Added options for max PDU size and session timeout to frontend-server.
1047 Added documentation of query-language parsers and other supporting utilities.
1049 [frontend-server] Added Attribute set to the bend_scanrequest API.
1051 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1052 surrogate diagnostics were generated.
1054 [retrieval] Allow multiple local values for attribute.
1056 [retrieval] Allow multiple attributes per element in .abs files. index type.
1058 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1060 --- 1.1pl2 1996/4/10
1062 Minor changes, mostly specific to Zebra's requirements (retrieval)
1066 Repaired bug in frontend server when running multiple listening
1067 endpoints in dynamic mode.
1069 z_External() now won't break if a known, ASN.1 value comes encapsulated
1070 in an octet-string. The value will pass through unmodified in an Odr_oct.
1072 Added a bit of code to the demo client to decode & display
1073 ASN.1-structured records represented in the octet-aligned branch of
1074 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1076 Added z_ext_getentbyref() to the ASN module. Doc updated.
1078 * Completed the SCAN definition in the ASN module. This may break SCAN
1079 code based on older YAZ-versions at compile-time. The fix is easy -
1082 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1083 under the SCAN definition. Remember to initialize this, server-people.
1085 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1086 that this does not extend to ODR and ASN.
1088 Comstack allows insertion of established socket (primarily for
1089 inetd-operation of servers). Doc updated.
1091 Front-end server can now start from the inetd in TCP mode. Doc
1094 --- 1.0pl4 1996/1/24
1098 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1099 the rank and record number.
1101 Adjustments to the frontend server.
1103 Fixed diagnostic BER dumper. It ignored the file argument.
1107 Various changes to retrieval module.
1109 Changed the union discriminators of the protocol files from enums to
1110 ints paired with #defines.
1112 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1115 *Changed operator in the RPN structure to 'roperator', again to avoid a
1118 Fixed problems in Explain decoders/encoders.
1120 --- 1.0pl2 1995/12/6
1122 Memory bug in log module fixed.
1124 --- 1.0pl1 1995/12/5
1126 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1128 Bug in Explain DatabaseInfo module fixed.
1130 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1134 The shift to v1.0 signals that we now consider the *core* functionality
1135 of YAZ reasonably stable (the core being more or less equivalent to
1136 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1137 tested (Explain not at all - though that will happen soonish).
1139 Minor changes to code to support Windows port.
1141 Various minor changes after we're getting to use GRS-1 & co. more.
1143 Added Espec-1 format.
1145 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1146 of the protocol and it cannot be selected when encoding (maps into 'string'
1147 when decoding). Needed to talk to some servers.
1149 Demo client can request simple element set names.
1151 Added Diagnostic Format encoders/decoders.
1153 Added simple Close handling to frontend server (no hooks for resource
1154 reporting yet), and demonstration client.
1156 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1158 --- 1.0b3 1995/08/24
1160 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1161 handled incorrectly when records were requested in the searchResponse. This
1162 will only affect you if you use the frontend-server.
1164 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1165 Test-client will ask for and print GRS1. Ztest will return dummy records
1168 Added Explain encoders/decoders to the service-level API. Untested.
1170 Added Extended Services: Item Order encoders and decoders to the Service-
1171 level API. Untested. We could use a recent copy of the pertinent bits
1172 of the ILL protocol to add those bits.
1174 Added diagnostic format 1 encoders/decoders to the service-level API.
1177 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1178 odr_cons.c, which causes a more correct output.
1180 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1181 was always set to 0 when no records were requested in the searchRequest.
1183 * Added better external-handling. This shouldn't harm old code that
1184 *encodes* externals. It can break code that looks for a
1185 'single-ASN1-type' representation, since those types that are known
1186 are now decoded immediately. Look at the SUTRS sample code in
1187 seshigh.c and client.c. Documentation updated.
1189 Handling of structured records in bend_fetchresponse. Length -1 marks
1190 structured record, type is deduced from format field.
1192 --- 1.0b2 1995/06/27
1193 Fairly quick maintenance release to add SUTRS support.
1195 Fixed handling of SUTRS records in the demonstration client.
1197 * Added format field to the bend_fetchrequest and bend_fetchresponce
1198 structures of the backend API (frontend server). When the record is
1199 returned, the value of the format field is mapped to an OID. The
1200 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1201 of the record. The special value VAL_NONE in the bend_request means
1202 that no specific format was requested by the client. Documentation
1203 updated accordingly. Test server (ztest) will return a fixed dummy
1204 SUTRS record if your client requests SUTRS.
1206 Documentation updated accordingly.
1208 You can now set external libraries and RANLIB support in the top-level
1212 First public release.
