1 Possible compatibility problems with earlier versions marked with '*'.
5 Added member 'schema' to bend_explain_rr structure so that backend
6 can specify explain record identifier. Defaults to Zeerex 2.0.
8 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
12 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
15 Added init command for yaz-client which sends "extra" init request.
17 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
18 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
20 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
22 Make ZOOM error code for "invalid query".
24 Fixed compilation for SSL which wasn't properly enabled for all platforms.
28 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
31 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
33 Added option -p <file> to make Generic Frontend Server to write PID file.
35 Added option -D to put Generic Frontend Server in background on its own.
37 Make ZOOM C recognize option "password". If unset, "pass" is used
38 (for backwards compatibility).
40 Fixed a bug in Generic Frontend Server that could make it crash if a
41 client sets characterSetNegotation bit, but didn't pass negotiation stuff
44 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
45 Must be issued before open, in order to be in effect.
47 --- 2.0.9-6 2004/01/12 Debian/Windows
49 Make the SRU server more picky WRT unknown params, etc.
51 Bug fix: ZOOM scan response didn't return displayTerm - when present.
53 New YAZ client command, options, that sets Z39.50 options.
55 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
56 options from a string of tokens (one token for each option bit).
58 Update SRW diagnostic code messages.
60 --- 2.0.9-5 2004/01/07 Debian/Windows
62 Handle user defined stylesheet for SRW/SRU.
64 --- 2.0.9-4 2004/01/06 Debian/Windows
66 Fix bug in decoding of Content-Length.
68 --- 2.0.9-3 2004/01/06 Debian/Windows
70 Fix a bug with decoding of XML packed records.
72 --- 2.0.9-2 2004/01/05 Debian only
74 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
76 Fix bug in SRW/SRU diagnostics decoding.
80 Fixed bug in Generic Frontend Server which could drop records exceeding
81 preferred message size. Reported and fixed by Irina Dijour.
83 Fixed calculation of package size for structured records in Generic
84 Frontend Server. Reported and fixed by Irina Dijour.
86 Fixed namespace for SRW/SRU diagnostics.
88 Fixed SEGV in yaz-client that occured for HTTP connection errors.
92 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
93 this version is incompatible with version 1.0 and older YAZ SRW/SRU
96 CQL changes to reflect recent changes to the specification:
97 * Documentation talks about context sets instead of index sets.
98 * Documentation talks about indexes instead of qualifiers.
99 * The CQL-to-PQF transformer's configuration file now uses
100 "index.set.name = <attributes>" instead of the old form
101 "qualifier.set.name = <attributes>". (Both forms are still
102 understood but the latter is deprecated.)
103 * CQL terms with no explicit index specified are now interpreted as
104 cql.serverChoice instead of srw.serverChoice (which of course
105 behaves exactly the same.)
109 MARC conversion can now generate ISO2709 output in another
110 character set. yaz-marcdump uses this facility if you invoke it
113 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
114 functions from there can be used from C++.
118 Frontend server now transfers memory from decoded packages to stream
121 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
122 references to show up.
124 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
125 the ZOOM Abstract API. The older names for the same options are still
126 also supported for the benefit of old applications.
128 ZOOM-C supports "implementationId" and "implementationVersion" options
129 to go along with "implementationName". These allow the user code to
130 specify identification strings to be sent to servers.
131 Add OID for the new ExtLite attribute set.
133 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
134 as requested/supplid by Ere Maijala <ere@atp.fi>
136 For generic frontend server, reverse the order of
137 "toolkit-supplied / application-supplied" strings sent as implementationId,
138 Name and Version. Also, remove the spaces around the slash. This brings
139 the GFS in line with the behaviour of ZOOM-C on the client side.
141 Add function ZOOM_scanset_display_term.
143 yaz-client shows scan displayTerm if present.
145 Utility yaz-iconv is now installed by default along with the man page
148 Extend configure check for OpenSSL to use pkg-config where available (such
151 Incorporate patch by Morten Bogeskov which allows a Unix file socket
152 server to specify uid/gid/mask for socket using the format
153 unix:[user=uid,][group=gid,][umask=mask,]file=path
154 If file= is omitted the existing format is assumed, e.g.
156 in which case the mask is 0666 (rw for everybody).
158 Major restructure of YAZ source. All source in libyaz is in src directory.
159 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
160 util (utility programs such as ASN.1 compiler, yaz-marcdump).
162 Added man page for utility yaz-marcdump (used to be called marcdump).
163 yaz-marcdump is installed by 'make install'.
165 Fixed a memory leak in Generic Frontend Server that occurred when decoding
166 of incoming package failed.
168 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
170 Change prototype of odr_perror: add const to message string.
172 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
174 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
175 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
176 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
177 DNS lookup. There should not be any compatibility problems with this
178 assuming that blocking=1 or 0 is used.
180 Fix bad reference in UNIX comstack in function cs_addrstr.
182 Fix for compilation on AIX.
184 The generic front-end server (server/seshigh.c) now supports returning
185 Init diagnostics to the client in User-information-field, in
186 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
191 Allow any CQL relation (not just all,any,exact,scr).
193 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
194 that features the same UI.
196 Implemented command update0 in YAZ client which is equivalent to
197 update but uses old of Ext Update ASN.1.
199 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
200 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
201 Previously no OID was used for this info.
203 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
204 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
205 returns 'malformed search term' otherwise.
207 SortResponse member resultCount now set to NULL in sort handler of
210 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
213 Add three new utility functions for translating OIDs between various
214 formats -- symbolic name such as "Usmarc", minus-1-terminated int
215 arrays and dotted strings such as "1.2.840.10003.9.5.1":
216 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
217 char *oid_to_dotstring(const int *oid, char *oidbuf);
218 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
220 Reverted modifications for ES Update definition for z_IU0Update
221 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
222 is back to YAZ 2.0.2.
224 String value attributes for CCL parser.
226 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
227 which their FirstSearch server returns in Init responses, sometimes
228 carrying useful diagnostic information when Init fails. This has the
229 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
230 "z39.50/oclcui.asn", where its definition is somewhat different from
231 what OCLC document on their web-site, as required to interoperate with
234 Support for anonymous authentication in yaz-client. Use the command
237 * Fix the OID of the Index Data-local "admin" Extended Service from
238 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
239 the 1000, which indicates a locally-defined OID, was a mistake.
243 Fix CCL directive @case handling so that it affects string match for
244 both CCL keywords and qualifiers.
246 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
247 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
248 Decoder has been updated with ASN.1 changes as listed in
249 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
250 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
251 z_IUUpdate, remains unchanged.
253 ZOOM_record_get may now return a record in a specific character set.
254 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
255 "from" is the character set of record as returned by target. "to" is
256 the character set to be returned. If omitted, "to" is UTF-8.
258 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
260 New ODR utility, odr_getelement, which returns name of element for
261 which encoding/decoding failed.
263 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
264 in cases where a required element was omitted.
266 Bug fix: some MARC8 sequences were not converted.
268 New ZOOM option "step" which specifies number of records to be
269 retrieved in one chunk. Used in conjunction with "start" and "count".
271 SRW support for yaz-client. Use scheme http: to use it, e.g.
274 yaz-client no longer does (un)intelligent character set conversions
275 by default. Can be enabled with charset and marc_charset commands.
277 xmalloc trace fix for 64-bit systems such as DEC alpha.
279 Solaris 2.6 compile fix.
281 New function, cql_strerror() translates SRW error codes, as returned
282 by cql_transform_error(), into human-readable English strings. Used
283 in yaz-client diagnostics when appropriate.
285 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
286 converts it into a type-1 query which is sent to the server. This
287 makes CQL available for use with all Z-servers, as opposed to the tiny
288 minority that can handle CQL queries themselves.
292 New Debian package layout similar to the Redhat Package layout.
294 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
295 and search result respectively.
299 Redhat package is now several packages: libyaz (runtime libraries),
300 libyaz-devel (development and documentation, and yaz (utility programs).
301 Package spec file by Morten Bøgeskov.
303 New member 'schema' in struct bend_fetch_rr which the name of requested
304 schema (SRW/SRU) for record (or NULL if none was given). The fetch
305 handler MAY set this to reflect the schema of the returned record.
307 New member 'display_term' in struct scan_entry. GFS now sets member entries
308 and allocates scan entries to be filled by user scan handler. In previous
309 version, entries member was allocated by the scan handler. That still works,
310 but the GFS will ignore member display_term - assuming it was NOT set by
311 the handler. The fact that the GFS now allocates the entries both allows
312 for new members and makes a scan handler easier to write.
314 Fix CQL lex buffer overflow.
316 SRW/SRU recordPacking. For SRW default recordPacking is string. For
317 SRU default recordPacking is string.
319 SRU protocol support for frontend server.
321 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
323 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
325 Added scan for the ZOOM shell (zoomsh).
329 * String Identifers for Schemas (Amendment 5).
330 http://lcweb.loc.gov/z3950/agency/amend/am5.html
331 Old definition for schema
332 Odr_oid *schema; /* OPT */
337 Z_InternationalString *uri;
338 #define Z_Schema_oid 1
339 #define Z_Schema_uri 2
342 * resultCount parameter to Sort Response (Amendment 1).
343 http://lcweb.loc.gov/z3950/agency/amend/am1.html
345 Support for SRW 1.0 over HTTP. This is an optional feature and
346 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
349 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
350 on the same port. SRW SearchRetrieveRequests are mapped
351 to bend_init,bend_search,bend_fetch,bend_close.
353 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
355 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
356 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
358 ZOOM connections are SRW based if schem http is used for hostname
359 in connect, e.g. z = ZOOM_connection_new("http://myserver");
360 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
362 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
363 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
364 distance=n, order=true/false, relation=le, prox unit=word. If
365 n is omitted, distance 1 is used.
367 Fixed problem with C compiler include path in wrong order.
369 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
370 on Solaris. Patch from Ko van der Sloot.
372 New MARC decode API. All new functions operate on a yaz_marc_t
373 handle. The most important new functions are: yaz_marc_create,
374 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
375 decode and destroy respectively. Decoder can produce formats
376 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
377 include/yaz/marcdisp.h.
379 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
380 to UTF-8, UCS-32, wchar_t or Latin-1.
382 * Prototypes for yaz_iconv_-functions moved to separate header
383 include/yaz/yaz-iconv.h.
385 Make a few private functions 'static' in unix.c. This prevents
386 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
388 For ZOOM connection, the options targetImplementation{Id,Name,Version}
389 are set when Init Response is received.
391 New function ZOOM_connection_error_x similar to ZOOM_connection_error
392 but returns diagnostic set as well.
394 New function yaz_strerror which is a portable wrapper for
395 strerror/strerror_r/GetLastMessage.
397 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
398 is returned for MARC. If type is "oai", then OAI MARC is returned.
400 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
405 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
407 Fix bad race conditions on SIGTERM and terminate gracefully in
410 Move retrieval (data1) module to Zebra since nobody seems to be
413 Add GRS-1 render for ZOOM using same format as yaz-client.
417 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
419 Fix broken ESpec handling in data1 module.
421 SGML reader parses comments and makes them part of the data1 tree.
423 Added several type casts so that YAZ compiles as C++ code.
425 ZOOM didn't handle PDU encoding failures properly.
427 Added more Bib-1 diagnostics (approved extensions).
429 GNU configure: better check for iconv.
431 More portable use of accept, getpeername. Check for socklen_t. Use
432 int/size_t if socklen_t is not defined.
436 PQF parser rejects bad queries - including those with extra
437 characters in them. PQF parser used to silently ignore that.
438 Cleaner API for PQF added, which allows you to get detailed
439 error information for bad queries (see yaz/pquery.h).
441 Fixed bug in ZOOM_record_get for type "database".
443 Implemented mini iconv library supporting conversions between
444 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
446 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
450 Fixed ZOOM C record cache so that preferredRecordSyntax and
451 elementSetName is used to check for already fetched records.
455 Added three members in bend_initrequest structure to facilitate
456 character set negotiation.
458 Fixed a bug in frontend server that could cause indefinite
459 loops under rare conditions.
461 Revised character set utilities (charneg.h) so that encoding
462 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
464 For PQF, directive @term <type> sets term type for Scan/Search.
465 Here <type> is general, string, numeric, null. The term type
466 is inherited - just like @attr.
468 New call odr_set_charset that sets character set conversion for
469 international-strings on a ODR stream. Prototype is:
470 int odr_set_charset(ODR o, const char *to, const char *from);
471 The InternationalString is still represented as C string in YAZ
472 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
473 won't). On the protocol level, you can use any encoding.
475 Support for UNIX sockets in ZOOM.
477 Solaris recv sometimes returns errno == ENOENT. It is treated as
478 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
480 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
481 both client and server. Code by Morten Bøgeskov.
485 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
486 that they can be used directly from Visual Basic. You must recompile
487 your windows APP if you're using ZOOM.
489 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
490 Commands "lang" and "charset" sets language and character set respectively.
491 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
492 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
494 Attributes from multiple CCL fields may be OR'ed rather than merged
495 using directive "@field or". Fields are still merged by default -
496 equivalent to "@field merge".
498 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
501 Fixed bug in zget for parameter ExtendedServicesResponse.
507 Added PQF feature: '@attr type=value' may be written as '@type=value'.
509 Client displays USR.1:SearchResult-1 (hits per term).
511 Additional Search Info for search in Generic Frontend Server.
513 Fixed CCL parsing of "field=s".
515 WIN32 installer - using the excellent NSIS software from nullsoft.
517 Fixed CCL parsing of "field = - <number>".
519 Added function yaz_marc_decode that decodes MARC for line mode
520 display or XML (similar to that used by JZKit).
522 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
523 Z39.50. But ISO/ILL was, however.
525 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
526 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
528 http://lcweb.loc.gov/z3950/agency/amend/am2.html
529 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
533 New YAZ client features: Command completion and new commands:
534 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
535 Code provided by Jacob Poulsen.
537 New call oid_trav, that visits all registered OIDs via callback.
539 Function ZOOM_record_get now returns const char pointer rather than
540 void pointer. It saves a lot of type casts.
542 For YAZ client, command "auth" now allows you to set authentication
543 in IdPass style. It is enabled when three tokens are given - order
544 is user, group and password.
546 Fix memory leaks in MARC record handling for ZOOM.
548 New option for YAZ client, -k <kilobytes> that sets
549 maximum record size. Similar to -k option for generic frontend
550 server and yaz-ztest.
552 More fixes for scan. Non-zero stepSize handled. OID's fixes.
554 Prefix query parser reports "fail" when bad attribute set is given.
556 Fix in MARC decoder. Proximity logging. Fix for attribute set
557 in scan handler for server. Patches by Shigeru Ishida.
559 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
562 Configure option --with-openssl=<dir> now works when a directory is
563 specified. Patch provided by Morten Bøgeskov.
565 New option for YAZ client, -u <auth>, that sets authentication.
567 ZOOM fix: error information was sometimes "missing", since error
568 was cleared/reset too when it shouldn't.
570 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
574 Scan for ZOOM API. New object ZOOM_scanset. New functions
575 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
576 ZOOM_scanset_destroy.
578 New ZOOM function, ZOOM_connection_last_event, that returns type
579 of last event (such as "receive data", "send data", "apdu received",
582 New ZOOM option, schema, that specifies schema for retrieval.
584 New CCL feature. Qualifiers can be aliases for one or more
585 other qualifiers (if more than one is given, OR is used).
587 ZOOM uses named result sets if target supports it.
589 Two new YAZ client commands: . (dot, which sources a script of YAZ
590 client commands), and ! (to execute shell command.). Implemented
593 Working on Debian packages.
597 YAZ client enables named result sets only if target supports it.
599 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
601 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
602 with key="host" to get same result.
604 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
605 Function Z3950_resultset_record(s) returns references to records
606 "owned" by resultset. To become owner use Z3950_record_clone.
608 Function z_ext_record handles Extended Services. Thanks to
613 CCL Parser fix: ignore token comma when dealing with and-lists.
615 Documentation updates for COMSTACK.
617 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
618 Changed prototype Z3950_records. For some functions, int parameters
619 were changed to size_t.
621 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
624 New MARC decode/display function, marc_display_exl, which properly rejects
625 non-ISO2709 records. YAZ client uses it.
629 Fix bug: local attribute set wasn't set correctly in PQF strings.
633 * Old Z39.50 codecs no longer supported.
635 Added ZOOM C binding. See http://zoom.z3950.org/
637 Renamed states for COMSTACKs to avoid confusion with events.
639 Implemented cs_look and proper cs_rcvconnect.
641 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
643 Configure detects POSIX threads on OpenBSD.
645 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
646 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
648 When error is returned from present handler, non-surrogate diagnostic
649 is returned in present response (and fetch handler is no longer called).
651 * Minor adjustments to pquery parser (PQF). Token characters may be
652 escaped by using backslash (C-style).
654 PQF parser allows string attribute values to be specified. For @attr,
655 non-numeric characters after the equal-sign are treated as strings
656 (e.g. @attr 9=title).
658 CCL trunction character may be defined (@truncation in file)
660 * function zget_ExtendedServicesRequest sets waitAction to
661 waitIfPossible (was wait).
663 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
666 CCL operator names may be set in field definition files (CCL_bibset).
667 See ccl/bib1 for an example.
669 Fixes in ASN.1 compiler for C++ compatibility.
671 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
672 and "op_or" to avoid conflict with C++.
674 Fixed problem with GNU readline detection on Redhat 7.0.
676 Added step-size for Scan backend handler.
678 Fixed bug that made the frontend server crash when no attribute
679 set was specified for scan.
681 Front-end server automatically switches to original working directory
682 when installed as an NT service. Previously -w had to be specified to
685 Added extended attributes for retrieval module (data1), so that data1
686 records carry d1_readXML/SGML attributes. d1_read also supports
687 null-data rules ( <tag/>)
689 On UNIX when POSIX threads are available, a separate library libyazthread
690 is created. Programmers should link with that library and the yaz library
691 when using threads. The reason for the split was that some applications
692 on Linux, such as Apache, doesn't work well when using shared objects that
695 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
696 (or any frontend server) in SSL mode by specifying ssl: followed by
697 address. Only tested on UNIX.
699 Added feature for CCL module. Virtual structure s=al or s=ol generates
700 and-list and or-list respectively instead of phrase search.
704 * Added prefix "yaz_" for the functions log_init.., log_file.. and
705 log_mask_str. This was done to avoid name conflicts with other libraries
706 (such as other PHP extensions).
708 Added raw OID member for preferred record syntax (request_format_raw)
709 and returned record syntax (output_format_raw) for backend fetch method.
711 Config file yaz-config now accepts options so that it returns specific
712 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
714 Shared library support for UNIX using GNU libtool.
716 * Modified backend interface. Request/Response struct's replaced by
717 one read/write C struct. For example bend_fetchrequest and
718 bend_fetchresult have been replaced by single bend_fetch_rr struct.
719 Every handler - even search has to be registered in bend_init
720 handler. This means that the YAZ library no longer refers to
721 external functions and it makes it possible to make the whole
722 thing a single DLL/SO.
724 Added Segment handler for backend server.
726 Added Zmbol/Zebra administrative functions to YAZ client.
728 Threaded frontend server on UNIX (when POSIX Threads are available).
729 Starting the server with option -T enables multi-threading.
733 Added configure option --enable-comp/disable-comp to control use
734 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
735 located in sub directory asn.
737 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
738 in ${exec_prefix}/bin along with the other programs yaz-client and
741 GNU automake used to maintain makefiles.
745 Changed retrieval module so that we can load records with no abstract
746 syntax defined. Tagpaths in these records are fully composed of string
749 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
753 On UNIX, the generated makefile now supports a proper 'make install'.
754 The prefix can be set via GNU configure to set the install location
755 (default is /usr/local).
757 * YAZ programs client and ztest were renamed to yaz-client and
758 yaz-ztest to avoid conflicts when users install YAZ in "standard"
759 locations, such as /usr/bin,/usr/local/bin,etc.
761 * YAZ Header files were moved from include to include/yaz. YAZ Header
762 files are referred to as include <yaz/log.h> rather than <log.h>.
763 The YAZ include path (-I ..) is therefore the same as before. Programmers
764 should update their #include statements or use -Ipath/include/yaz
765 instead. The main motivation for doing this change is that YAZ header files
766 can be installed in "standard" locations /usr/include,/usr/local/include
767 without introducing conflicts, since ALL YAZ header files are stored
768 in subdirectory yaz (under /usr/include for example).
770 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
771 rather than project/workspace files. We switched because project files
772 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
775 Changed name of logging function, logf, to yaz_log, to prevent name
776 clash with some math-log functions. The YAZ header log.h defines logf
777 to yaz_log (#define) so there should be no incompatibilities by this
780 Added bend_start/bend_stop handlers for server. These handler are
781 called on start/stop of server. For windows they are called whenever
782 a service is started/stopped.
784 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
785 a fairly small ASN.1 compiler written in Tcl. The compiler is located
786 in util/yc.tcl. The auto-generated C code structures are, in a few
787 cases, incompatible with the old decoders. There are differences in the
788 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
789 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
790 The preprocessor variable ASN_COMPILED is defined when the compiled
791 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
792 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
793 wish to use the old encoders/decoders you can specify --disable-yc
796 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
797 version so that it supports both new - and old version of DB Update
799 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
800 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
801 change. The name parameter can be set to 0 in which no name is specified
802 for the construction. The macros odr_implicit and odr_explicit sets name
803 parameter to zero for the construction involved. New macros
804 odr_implicit_tag and odr_explicit_tag are similar to the others,
805 except that a name parameter is added. For programmers' that don't use
806 ODR they probably only need to change the call to z_APDU and z_External.
808 Added access control facility by interfacing the TCP wrapper library.
809 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
810 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
811 name of the daemon and enables the access control as specified in
812 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
814 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
815 den Dool <H.M.vdnDool@kub.nl>.
817 Added reference ID parameter to most functions in server API - refer
818 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
820 Changed name of ccl library to libccl.a (was ccl.a).
822 Fixed bug in decoder for Explain (Category TargetInfo).
824 Added support for GNU readline in client. Thanks to Jacob Poulsen
825 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
827 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
828 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
829 IMPLEMENTATION! This change was made to the development version before
830 the ZIG decided to retract the amendment. If any users MUST be
831 compatible with the original Update definition, PLEASE CONTACT US, and
832 we will include a separate definition corresponding to the old Update
833 ES. Note that because of the change to the ASN.1 of the
834 TaskPackageRecordStructure we cannot define a single structure that
835 will support both versions.
837 * Added const modifier to buffer parameter for some ODR/BER encoding
838 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
839 completeWAIS, odr_dumpBER.
841 Fixed bug in client.c which caused a crash when a scanResponse didn't
842 contain positionOfTerm.
844 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
845 * will cause an error in a client if a non-YAZ target sends both a
846 * list of Scan entries and non-surrogate diagnostics.
848 Retrieval module enhancements. Tag sets may be typed in the reference
849 to it. From the .abs-file the "tagset" directive takes a third optional
850 integer type for the tag set referenced. From a .tag-file the "include"
851 directive takes a third optional type as well. The old "type" directive
852 in the tag set itself is still recognized but acts as the default type
855 Backend interface change. Individual Scan terms returned from bend_scan
856 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
857 in include/backend.h.
859 Retrieval module enhancements. Multiple tag sets and attribute sets may
860 be specified in abstract syntax specs. Revised the error/warning for
861 logging messages reported by the retrieval module when reading the
864 Object Identifier system (oid_..) changed. The API is backwards
865 compatible but the oid-routines now allocates new OID's when needed.
866 Raw OID's may be specified in oid_getvalbyname.
868 YAZ now uses GNU configure to generate Makefile(s).
870 * Minor changes in some of the member names of DeleteResultSetRequest and
871 DeleteResultSetResponse. See include/proto.h.
873 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
874 and added member 'languages' in TargetInfo (which was missing).
876 Changed the way attribute sets are handled in the retrieval
877 module. These are now cached, just like the abstract syntaxes
880 Changed YAZ so that it links with compiled ASN.1.
882 Added Explain-schema definitions and mapping routines. The following
883 Explain categories have been implemented: AttributeDetails,
884 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
886 Fixed minor bug in Windows version of Server Library.
888 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
890 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
892 Added EXTERNAL: UNIverse Resource Report (non-standard).
894 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
895 ENUMERATED and SET OF.
897 * Added 'const' to some of the char pointer arguments for the
898 functions, data1_read_node, data1_getelementbytagname,
899 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
902 Fixed bug in data1_insert_taggeddata - the last_child member of
903 parent wasn't initialised.
905 * Changed data1_read_record and data1_read_node so that the supplied
906 "SGML"-buffer is read-only. In particular the resulting data1 - tree
907 doesn't refer to any parts of the "SGML"-buffer.
909 Fixed bug in server library (Windows version of statserv_remove).
911 * Changed code so that it compiles as C++. The type definition
912 of Odr_fun which is a member of Odr_arm was changed. The result is,
913 that an explicit typecast is needed for the fun pointer when
914 using Odr_arm - as in:
915 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
917 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
919 Implemented the new structured date and time definition as approved
920 by the ZIG. Added schemaId element to the specificTag in Espec-1
921 (also approved at the last ZIG). Thanks to RVDM.
923 Added some Object identifiers (RVDM).
925 Changed the Update Extended Service (RVDM).
927 Added command "refid" to client which specifies referenceId for
928 the following requests.
930 Implemented extended service handling for server. See ztest.c
931 for an example as well as backend.h. New handlers are registerd
934 * Changed interface for sort in server.
936 Added new members to statserv_options_block. It allows a server
937 to read options from another source than just the command line. Thanks
938 to Charles Woodfield.
940 * Changed definition of Z_Triple in file prt-grs.h - member boolean
941 renamed to zboolean. Some C++ compilers complained about the name.
943 Minor changes to gils.abs. Added index 's' (sort) on title
944 and date/time-last-modified.
948 Fixed bug in server library regarding inetd mode (-i). This bug
949 was introduced by release 1.4.
953 Added sort facility in client and backend server interface.
955 Fixed problem with dependencies in Makefile(s).
957 Fixed bugs for encoders/decoders of extended services and
960 Implemented sub-tree feature for schemas. Sub-trees are
961 referenced in *.abs-files. See explain.abs for an example
962 of the use of this feature.
964 Modified bib1.att; local attributes for ANY didn't include
965 ANY itself (only affects use of the retrieval module).
967 Fixed bug in plain SGML reader in function data1_read_node:
968 tags with prefix "var" was incorrectly interpreted as variants.
970 Added feature "sub-schemas" to enable references to - and definitions
971 of - group of elements.
973 * Removed member parent from type data1_element (in data1.h).
975 Implemented function odr_nullval() that returns the value of
978 * Removed member num_children from data1_node (in data1.h).
980 Made NT service interface part of the server library. The
981 function statserv_main uses the NT service when required and
982 calls the statserv_start / statserv_close routines.
984 Routine zget_SearchRequest and zget_PresentRequest fills
985 resultSetName/Id member with "default" instead of "Default".
987 Fixed memory leak in server. Request queue member wasn't freed.
989 Fixed nmem_exit so that memory is freed.
993 Revised the CCL parser utility to be thread safe.
995 Added function, oid_ent_to_oid, to replace the function
996 oid_getoidbyent, which is not thread safe.
998 * Added nmem_init and nmem_exit to initialize and release
999 NMEM resources. Function nmem_init should be called once in the
1000 initial thread before NMEM/ODR is used. statserv.c and client.c
1001 have been changed accordingly. The change was necessary to make
1002 NMEM thread safe. The NMEM memory pool is shared amongst threads
1003 in a process. Unix-based applications will still work fine without
1006 Added NT Services interface for the the Z39.50 (statserv) Server.
1007 Refer to the ztest.c source on the usage.
1009 Windows 95/NT port using MSVC5.0. Project files are included in the
1012 * Defined new 'global' handle for the retrieval (data1) system. The
1013 new handled, data1_handle, describes the state of the data1 system.
1014 This handle is passed as first argument to virtually all
1015 data1 related routines. The functions data1_create and data1_destroy
1016 creates and destroys a data1 handle respectively.
1018 Added ODR encode stream member to all backend request structures
1019 init, search, scan etc. This stream should be used to allocate all
1020 memory used for the response when thread safe operation is needed.
1022 Changed the comstack utility, cs_addstr, to be thread safe. The
1023 returned hostname string returned by the function is now part the
1026 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1027 function. The cs_straddr takes a COMSTACK handle as argument, so this
1028 function must be used after cs_create and before bind/connect.
1029 This function is thread safe.
1031 Moved test server to 'ztest' directory - generic server code still
1032 in 'server' directory.
1034 Made prefix query (pquery.c) utility thread safe.
1036 Added new function modifier YAZ_EXPORT to 'export' public DLL
1037 functions when using windows (see include/yconfig.h).
1039 Added definitions to the OID database (util/oid.c) (RVDM).
1041 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1043 Added call to ccl_rpn_delete in client program.
1045 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1046 release of RPN structure.
1048 Added support for C++, headers uses extern "C" for public definitions.
1049 With input from RVDM.
1051 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1052 Thanks to Ronald van der Meer (RVDM).
1054 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1056 Added support for private extensions to the OID database
1057 (oid_setprivateoids()). Thanks to RVDM.
1059 Added optional, physical ANY (key replication)
1061 Fixed null-reference problem in GRS-1 output filter.
1063 Proximity operator added to Prefix Query Format (PQF).
1065 In test client command "base" accepts multiple databases.
1067 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1071 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1073 Smallish bug-fixes in the new encoders/decoders (explain).
1075 Bug fixed in DeleteRequest.
1077 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1079 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1081 Added SOIF syntax (using private OID for now) to retrieval module and client.
1083 Added Update extended service.
1085 Added SearchResult-1 additional info structure.
1087 Added optional CCL (ISO8777) interpreter as separate module. Available
1090 --- 1.2 1996/6/10 (1st anniversary release)
1092 Added Summary record syntax. Lightly tested.
1094 Added OPAC record syntax. Untested.
1096 Added ResourceReport service encoders/decoders. Untested.
1098 Fixed bug in z_Unit - wrong tagging on unitSystem.
1100 Fixed bug in the DiagRecs decoder.
1102 Added options for max PDU size and session timeout to frontend-server.
1104 Added documentation of query-language parsers and other supporting utilities.
1106 [frontend-server] Added Attribute set to the bend_scanrequest API.
1108 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1109 surrogate diagnostics were generated.
1111 [retrieval] Allow multiple local values for attribute.
1113 [retrieval] Allow multiple attributes per element in .abs files. index type.
1115 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1117 --- 1.1pl2 1996/4/10
1119 Minor changes, mostly specific to Zebra's requirements (retrieval)
1123 Repaired bug in frontend server when running multiple listening
1124 endpoints in dynamic mode.
1126 z_External() now won't break if a known, ASN.1 value comes encapsulated
1127 in an octet-string. The value will pass through unmodified in an Odr_oct.
1129 Added a bit of code to the demo client to decode & display
1130 ASN.1-structured records represented in the octet-aligned branch of
1131 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1133 Added z_ext_getentbyref() to the ASN module. Doc updated.
1135 * Completed the SCAN definition in the ASN module. This may break SCAN
1136 code based on older YAZ-versions at compile-time. The fix is easy -
1139 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1140 under the SCAN definition. Remember to initialize this, server-people.
1142 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1143 that this does not extend to ODR and ASN.
1145 Comstack allows insertion of established socket (primarily for
1146 inetd-operation of servers). Doc updated.
1148 Front-end server can now start from the inetd in TCP mode. Doc
1151 --- 1.0pl4 1996/1/24
1155 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1156 the rank and record number.
1158 Adjustments to the frontend server.
1160 Fixed diagnostic BER dumper. It ignored the file argument.
1164 Various changes to retrieval module.
1166 Changed the union discriminators of the protocol files from enums to
1167 ints paired with #defines.
1169 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1172 *Changed operator in the RPN structure to 'roperator', again to avoid a
1175 Fixed problems in Explain decoders/encoders.
1177 --- 1.0pl2 1995/12/6
1179 Memory bug in log module fixed.
1181 --- 1.0pl1 1995/12/5
1183 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1185 Bug in Explain DatabaseInfo module fixed.
1187 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1191 The shift to v1.0 signals that we now consider the *core* functionality
1192 of YAZ reasonably stable (the core being more or less equivalent to
1193 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1194 tested (Explain not at all - though that will happen soonish).
1196 Minor changes to code to support Windows port.
1198 Various minor changes after we're getting to use GRS-1 & co. more.
1200 Added Espec-1 format.
1202 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1203 of the protocol and it cannot be selected when encoding (maps into 'string'
1204 when decoding). Needed to talk to some servers.
1206 Demo client can request simple element set names.
1208 Added Diagnostic Format encoders/decoders.
1210 Added simple Close handling to frontend server (no hooks for resource
1211 reporting yet), and demonstration client.
1213 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1215 --- 1.0b3 1995/08/24
1217 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1218 handled incorrectly when records were requested in the searchResponse. This
1219 will only affect you if you use the frontend-server.
1221 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1222 Test-client will ask for and print GRS1. Ztest will return dummy records
1225 Added Explain encoders/decoders to the service-level API. Untested.
1227 Added Extended Services: Item Order encoders and decoders to the Service-
1228 level API. Untested. We could use a recent copy of the pertinent bits
1229 of the ILL protocol to add those bits.
1231 Added diagnostic format 1 encoders/decoders to the service-level API.
1234 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1235 odr_cons.c, which causes a more correct output.
1237 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1238 was always set to 0 when no records were requested in the searchRequest.
1240 * Added better external-handling. This shouldn't harm old code that
1241 *encodes* externals. It can break code that looks for a
1242 'single-ASN1-type' representation, since those types that are known
1243 are now decoded immediately. Look at the SUTRS sample code in
1244 seshigh.c and client.c. Documentation updated.
1246 Handling of structured records in bend_fetchresponse. Length -1 marks
1247 structured record, type is deduced from format field.
1249 --- 1.0b2 1995/06/27
1250 Fairly quick maintenance release to add SUTRS support.
1252 Fixed handling of SUTRS records in the demonstration client.
1254 * Added format field to the bend_fetchrequest and bend_fetchresponce
1255 structures of the backend API (frontend server). When the record is
1256 returned, the value of the format field is mapped to an OID. The
1257 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1258 of the record. The special value VAL_NONE in the bend_request means
1259 that no specific format was requested by the client. Documentation
1260 updated accordingly. Test server (ztest) will return a fixed dummy
1261 SUTRS record if your client requests SUTRS.
1263 Documentation updated accordingly.
1265 You can now set external libraries and RANLIB support in the top-level
1269 First public release.
