1 Possible compatibility problems with earlier versions marked with '*'.
3 --- 2.0.9-2 2004/01/05 Debian only
5 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
7 Fix bug in SRW/SRU diagnostics decoding.
11 Fixed bug in Generic Frontend Server which could drop records exceeding
12 preferred message size. Reported and fixed by Irina Dijour.
14 Fixed calculation of package size for structured records in Generic
15 Frontend Server. Reported and fixed by Irina Dijour.
17 Fixed namespace for SRW/SRU diagnostics.
19 Fixed SEGV in yaz-client that occured for HTTP connection errors.
23 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
24 this version is incompatible with version 1.0 and older YAZ SRW/SRU
27 CQL changes to reflect recent changes to the specification:
28 * Documentation talks about context sets instead of index sets.
29 * Documentation talks about indexes instead of qualifiers.
30 * The CQL-to-PQF transformer's configuration file now uses
31 "index.set.name = <attributes>" instead of the old form
32 "qualifier.set.name = <attributes>". (Both forms are still
33 understood but the latter is deprecated.)
34 * CQL terms with no explicit index specified are now interpreted as
35 cql.serverChoice instead of srw.serverChoice (which of course
36 behaves exactly the same.)
40 MARC conversion can now generate ISO2709 output in another
41 character set. yaz-marcdump uses this facility if you invoke it
44 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
45 functions from there can be used from C++.
49 Frontend server now transfers memory from decoded packages to stream
52 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
53 references to show up.
55 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
56 the ZOOM Abstract API. The older names for the same options are still
57 also supported for the benefit of old applications.
59 ZOOM-C supports "implementationId" and "implementationVersion" options
60 to go along with "implementationName". These allow the user code to
61 specify identification strings to be sent to servers.
62 Add OID for the new ExtLite attribute set.
64 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
65 as requested/supplid by Ere Maijala <ere@atp.fi>
67 For generic frontend server, reverse the order of
68 "toolkit-supplied / application-supplied" strings sent as implementationId,
69 Name and Version. Also, remove the spaces around the slash. This brings
70 the GFS in line with the behaviour of ZOOM-C on the client side.
72 Add function ZOOM_scanset_display_term.
74 yaz-client shows scan displayTerm if present.
76 Utility yaz-iconv is now installed by default along with the man page
79 Extend configure check for OpenSSL to use pkg-config where available (such
82 Incorporate patch by Morten Bogeskov which allows a Unix file socket
83 server to specify uid/gid/mask for socket using the format
84 unix:[user=uid,][group=gid,][umask=mask,]file=path
85 If file= is omitted the existing format is assumed, e.g.
87 in which case the mask is 0666 (rw for everybody).
89 Major restructure of YAZ source. All source in libyaz is in src directory.
90 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
91 util (utility programs such as ASN.1 compiler, yaz-marcdump).
93 Added man page for utility yaz-marcdump (used to be called marcdump).
94 yaz-marcdump is installed by 'make install'.
96 Fixed a memory leak in Generic Frontend Server that occurred when decoding
97 of incoming package failed.
99 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
101 Change prototype of odr_perror: add const to message string.
103 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
105 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
106 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
107 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
108 DNS lookup. There should not be any compatibility problems with this
109 assuming that blocking=1 or 0 is used.
111 Fix bad reference in UNIX comstack in function cs_addrstr.
113 Fix for compilation on AIX.
115 The generic front-end server (server/seshigh.c) now supports returning
116 Init diagnostics to the client in User-information-field, in
117 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
122 Allow any CQL relation (not just all,any,exact,scr).
124 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
125 that features the same UI.
127 Implemented command update0 in YAZ client which is equivalent to
128 update but uses old of Ext Update ASN.1.
130 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
131 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
132 Previously no OID was used for this info.
134 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
135 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
136 returns 'malformed search term' otherwise.
138 SortResponse member resultCount now set to NULL in sort handler of
141 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
144 Add three new utility functions for translating OIDs between various
145 formats -- symbolic name such as "Usmarc", minus-1-terminated int
146 arrays and dotted strings such as "1.2.840.10003.9.5.1":
147 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
148 char *oid_to_dotstring(const int *oid, char *oidbuf);
149 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
151 Reverted modifications for ES Update definition for z_IU0Update
152 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
153 is back to YAZ 2.0.2.
155 String value attributes for CCL parser.
157 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
158 which their FirstSearch server returns in Init responses, sometimes
159 carrying useful diagnostic information when Init fails. This has the
160 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
161 "z39.50/oclcui.asn", where its definition is somewhat different from
162 what OCLC document on their web-site, as required to interoperate with
165 Support for anonymous authentication in yaz-client. Use the command
168 * Fix the OID of the Index Data-local "admin" Extended Service from
169 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
170 the 1000, which indicates a locally-defined OID, was a mistake.
174 Fix CCL directive @case handling so that it affects string match for
175 both CCL keywords and qualifiers.
177 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
178 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
179 Decoder has been updated with ASN.1 changes as listed in
180 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
181 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
182 z_IUUpdate, remains unchanged.
184 ZOOM_record_get may now return a record in a specific character set.
185 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
186 "from" is the character set of record as returned by target. "to" is
187 the character set to be returned. If omitted, "to" is UTF-8.
189 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
191 New ODR utility, odr_getelement, which returns name of element for
192 which encoding/decoding failed.
194 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
195 in cases where a required element was omitted.
197 Bug fix: some MARC8 sequences were not converted.
199 New ZOOM option "step" which specifies number of records to be
200 retrieved in one chunk. Used in conjunction with "start" and "count".
202 SRW support for yaz-client. Use scheme http: to use it, e.g.
205 yaz-client no longer does (un)intelligent character set conversions
206 by default. Can be enabled with charset and marc_charset commands.
208 xmalloc trace fix for 64-bit systems such as DEC alpha.
210 Solaris 2.6 compile fix.
212 New function, cql_strerror() translates SRW error codes, as returned
213 by cql_transform_error(), into human-readable English strings. Used
214 in yaz-client diagnostics when appropriate.
216 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
217 converts it into a type-1 query which is sent to the server. This
218 makes CQL available for use with all Z-servers, as opposed to the tiny
219 minority that can handle CQL queries themselves.
223 New Debian package layout similar to the Redhat Package layout.
225 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
226 and search result respectively.
230 Redhat package is now several packages: libyaz (runtime libraries),
231 libyaz-devel (development and documentation, and yaz (utility programs).
232 Package spec file by Morten Bøgeskov.
234 New member 'schema' in struct bend_fetch_rr which the name of requested
235 schema (SRW/SRU) for record (or NULL if none was given). The fetch
236 handler MAY set this to reflect the schema of the returned record.
238 New member 'display_term' in struct scan_entry. GFS now sets member entries
239 and allocates scan entries to be filled by user scan handler. In previous
240 version, entries member was allocated by the scan handler. That still works,
241 but the GFS will ignore member display_term - assuming it was NOT set by
242 the handler. The fact that the GFS now allocates the entries both allows
243 for new members and makes a scan handler easier to write.
245 Fix CQL lex buffer overflow.
247 SRW/SRU recordPacking. For SRW default recordPacking is string. For
248 SRU default recordPacking is string.
250 SRU protocol support for frontend server.
252 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
254 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
256 Added scan for the ZOOM shell (zoomsh).
260 * String Identifers for Schemas (Amendment 5).
261 http://lcweb.loc.gov/z3950/agency/amend/am5.html
262 Old definition for schema
263 Odr_oid *schema; /* OPT */
268 Z_InternationalString *uri;
269 #define Z_Schema_oid 1
270 #define Z_Schema_uri 2
273 * resultCount parameter to Sort Response (Amendment 1).
274 http://lcweb.loc.gov/z3950/agency/amend/am1.html
276 Support for SRW 1.0 over HTTP. This is an optional feature and
277 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
280 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
281 on the same port. SRW SearchRetrieveRequests are mapped
282 to bend_init,bend_search,bend_fetch,bend_close.
284 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
286 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
287 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
289 ZOOM connections are SRW based if schem http is used for hostname
290 in connect, e.g. z = ZOOM_connection_new("http://myserver");
291 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
293 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
294 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
295 distance=n, order=true/false, relation=le, prox unit=word. If
296 n is omitted, distance 1 is used.
298 Fixed problem with C compiler include path in wrong order.
300 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
301 on Solaris. Patch from Ko van der Sloot.
303 New MARC decode API. All new functions operate on a yaz_marc_t
304 handle. The most important new functions are: yaz_marc_create,
305 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
306 decode and destroy respectively. Decoder can produce formats
307 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
308 include/yaz/marcdisp.h.
310 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
311 to UTF-8, UCS-32, wchar_t or Latin-1.
313 * Prototypes for yaz_iconv_-functions moved to separate header
314 include/yaz/yaz-iconv.h.
316 Make a few private functions 'static' in unix.c. This prevents
317 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
319 For ZOOM connection, the options targetImplementation{Id,Name,Version}
320 are set when Init Response is received.
322 New function ZOOM_connection_error_x similar to ZOOM_connection_error
323 but returns diagnostic set as well.
325 New function yaz_strerror which is a portable wrapper for
326 strerror/strerror_r/GetLastMessage.
328 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
329 is returned for MARC. If type is "oai", then OAI MARC is returned.
331 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
336 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
338 Fix bad race conditions on SIGTERM and terminate gracefully in
341 Move retrieval (data1) module to Zebra since nobody seems to be
344 Add GRS-1 render for ZOOM using same format as yaz-client.
348 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
350 Fix broken ESpec handling in data1 module.
352 SGML reader parses comments and makes them part of the data1 tree.
354 Added several type casts so that YAZ compiles as C++ code.
356 ZOOM didn't handle PDU encoding failures properly.
358 Added more Bib-1 diagnostics (approved extensions).
360 GNU configure: better check for iconv.
362 More portable use of accept, getpeername. Check for socklen_t. Use
363 int/size_t if socklen_t is not defined.
367 PQF parser rejects bad queries - including those with extra
368 characters in them. PQF parser used to silently ignore that.
369 Cleaner API for PQF added, which allows you to get detailed
370 error information for bad queries (see yaz/pquery.h).
372 Fixed bug in ZOOM_record_get for type "database".
374 Implemented mini iconv library supporting conversions between
375 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
377 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
381 Fixed ZOOM C record cache so that preferredRecordSyntax and
382 elementSetName is used to check for already fetched records.
386 Added three members in bend_initrequest structure to facilitate
387 character set negotiation.
389 Fixed a bug in frontend server that could cause indefinite
390 loops under rare conditions.
392 Revised character set utilities (charneg.h) so that encoding
393 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
395 For PQF, directive @term <type> sets term type for Scan/Search.
396 Here <type> is general, string, numeric, null. The term type
397 is inherited - just like @attr.
399 New call odr_set_charset that sets character set conversion for
400 international-strings on a ODR stream. Prototype is:
401 int odr_set_charset(ODR o, const char *to, const char *from);
402 The InternationalString is still represented as C string in YAZ
403 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
404 won't). On the protocol level, you can use any encoding.
406 Support for UNIX sockets in ZOOM.
408 Solaris recv sometimes returns errno == ENOENT. It is treated as
409 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
411 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
412 both client and server. Code by Morten Bøgeskov.
416 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
417 that they can be used directly from Visual Basic. You must recompile
418 your windows APP if you're using ZOOM.
420 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
421 Commands "lang" and "charset" sets language and character set respectively.
422 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
423 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
425 Attributes from multiple CCL fields may be OR'ed rather than merged
426 using directive "@field or". Fields are still merged by default -
427 equivalent to "@field merge".
429 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
432 Fixed bug in zget for parameter ExtendedServicesResponse.
438 Added PQF feature: '@attr type=value' may be written as '@type=value'.
440 Client displays USR.1:SearchResult-1 (hits per term).
442 Additional Search Info for search in Generic Frontend Server.
444 Fixed CCL parsing of "field=s".
446 WIN32 installer - using the excellent NSIS software from nullsoft.
448 Fixed CCL parsing of "field = - <number>".
450 Added function yaz_marc_decode that decodes MARC for line mode
451 display or XML (similar to that used by JZKit).
453 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
454 Z39.50. But ISO/ILL was, however.
456 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
457 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
459 http://lcweb.loc.gov/z3950/agency/amend/am2.html
460 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
464 New YAZ client features: Command completion and new commands:
465 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
466 Code provided by Jacob Poulsen.
468 New call oid_trav, that visits all registered OIDs via callback.
470 Function ZOOM_record_get now returns const char pointer rather than
471 void pointer. It saves a lot of type casts.
473 For YAZ client, command "auth" now allows you to set authentication
474 in IdPass style. It is enabled when three tokens are given - order
475 is user, group and password.
477 Fix memory leaks in MARC record handling for ZOOM.
479 New option for YAZ client, -k <kilobytes> that sets
480 maximum record size. Similar to -k option for generic frontend
481 server and yaz-ztest.
483 More fixes for scan. Non-zero stepSize handled. OID's fixes.
485 Prefix query parser reports "fail" when bad attribute set is given.
487 Fix in MARC decoder. Proximity logging. Fix for attribute set
488 in scan handler for server. Patches by Shigeru Ishida.
490 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
493 Configure option --with-openssl=<dir> now works when a directory is
494 specified. Patch provided by Morten Bøgeskov.
496 New option for YAZ client, -u <auth>, that sets authentication.
498 ZOOM fix: error information was sometimes "missing", since error
499 was cleared/reset too when it shouldn't.
501 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
505 Scan for ZOOM API. New object ZOOM_scanset. New functions
506 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
507 ZOOM_scanset_destroy.
509 New ZOOM function, ZOOM_connection_last_event, that returns type
510 of last event (such as "receive data", "send data", "apdu received",
513 New ZOOM option, schema, that specifies schema for retrieval.
515 New CCL feature. Qualifiers can be aliases for one or more
516 other qualifiers (if more than one is given, OR is used).
518 ZOOM uses named result sets if target supports it.
520 Two new YAZ client commands: . (dot, which sources a script of YAZ
521 client commands), and ! (to execute shell command.). Implemented
524 Working on Debian packages.
528 YAZ client enables named result sets only if target supports it.
530 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
532 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
533 with key="host" to get same result.
535 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
536 Function Z3950_resultset_record(s) returns references to records
537 "owned" by resultset. To become owner use Z3950_record_clone.
539 Function z_ext_record handles Extended Services. Thanks to
544 CCL Parser fix: ignore token comma when dealing with and-lists.
546 Documentation updates for COMSTACK.
548 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
549 Changed prototype Z3950_records. For some functions, int parameters
550 were changed to size_t.
552 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
555 New MARC decode/display function, marc_display_exl, which properly rejects
556 non-ISO2709 records. YAZ client uses it.
560 Fix bug: local attribute set wasn't set correctly in PQF strings.
564 * Old Z39.50 codecs no longer supported.
566 Added ZOOM C binding. See http://zoom.z3950.org/
568 Renamed states for COMSTACKs to avoid confusion with events.
570 Implemented cs_look and proper cs_rcvconnect.
572 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
574 Configure detects POSIX threads on OpenBSD.
576 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
577 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
579 When error is returned from present handler, non-surrogate diagnostic
580 is returned in present response (and fetch handler is no longer called).
582 * Minor adjustments to pquery parser (PQF). Token characters may be
583 escaped by using backslash (C-style).
585 PQF parser allows string attribute values to be specified. For @attr,
586 non-numeric characters after the equal-sign are treated as strings
587 (e.g. @attr 9=title).
589 CCL trunction character may be defined (@truncation in file)
591 * function zget_ExtendedServicesRequest sets waitAction to
592 waitIfPossible (was wait).
594 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
597 CCL operator names may be set in field definition files (CCL_bibset).
598 See ccl/bib1 for an example.
600 Fixes in ASN.1 compiler for C++ compatibility.
602 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
603 and "op_or" to avoid conflict with C++.
605 Fixed problem with GNU readline detection on Redhat 7.0.
607 Added step-size for Scan backend handler.
609 Fixed bug that made the frontend server crash when no attribute
610 set was specified for scan.
612 Front-end server automatically switches to original working directory
613 when installed as an NT service. Previously -w had to be specified to
616 Added extended attributes for retrieval module (data1), so that data1
617 records carry d1_readXML/SGML attributes. d1_read also supports
618 null-data rules ( <tag/>)
620 On UNIX when POSIX threads are available, a separate library libyazthread
621 is created. Programmers should link with that library and the yaz library
622 when using threads. The reason for the split was that some applications
623 on Linux, such as Apache, doesn't work well when using shared objects that
626 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
627 (or any frontend server) in SSL mode by specifying ssl: followed by
628 address. Only tested on UNIX.
630 Added feature for CCL module. Virtual structure s=al or s=ol generates
631 and-list and or-list respectively instead of phrase search.
635 * Added prefix "yaz_" for the functions log_init.., log_file.. and
636 log_mask_str. This was done to avoid name conflicts with other libraries
637 (such as other PHP extensions).
639 Added raw OID member for preferred record syntax (request_format_raw)
640 and returned record syntax (output_format_raw) for backend fetch method.
642 Config file yaz-config now accepts options so that it returns specific
643 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
645 Shared library support for UNIX using GNU libtool.
647 * Modified backend interface. Request/Response struct's replaced by
648 one read/write C struct. For example bend_fetchrequest and
649 bend_fetchresult have been replaced by single bend_fetch_rr struct.
650 Every handler - even search has to be registered in bend_init
651 handler. This means that the YAZ library no longer refers to
652 external functions and it makes it possible to make the whole
653 thing a single DLL/SO.
655 Added Segment handler for backend server.
657 Added Zmbol/Zebra administrative functions to YAZ client.
659 Threaded frontend server on UNIX (when POSIX Threads are available).
660 Starting the server with option -T enables multi-threading.
664 Added configure option --enable-comp/disable-comp to control use
665 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
666 located in sub directory asn.
668 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
669 in ${exec_prefix}/bin along with the other programs yaz-client and
672 GNU automake used to maintain makefiles.
676 Changed retrieval module so that we can load records with no abstract
677 syntax defined. Tagpaths in these records are fully composed of string
680 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
684 On UNIX, the generated makefile now supports a proper 'make install'.
685 The prefix can be set via GNU configure to set the install location
686 (default is /usr/local).
688 * YAZ programs client and ztest were renamed to yaz-client and
689 yaz-ztest to avoid conflicts when users install YAZ in "standard"
690 locations, such as /usr/bin,/usr/local/bin,etc.
692 * YAZ Header files were moved from include to include/yaz. YAZ Header
693 files are referred to as include <yaz/log.h> rather than <log.h>.
694 The YAZ include path (-I ..) is therefore the same as before. Programmers
695 should update their #include statements or use -Ipath/include/yaz
696 instead. The main motivation for doing this change is that YAZ header files
697 can be installed in "standard" locations /usr/include,/usr/local/include
698 without introducing conflicts, since ALL YAZ header files are stored
699 in subdirectory yaz (under /usr/include for example).
701 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
702 rather than project/workspace files. We switched because project files
703 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
706 Changed name of logging function, logf, to yaz_log, to prevent name
707 clash with some math-log functions. The YAZ header log.h defines logf
708 to yaz_log (#define) so there should be no incompatibilities by this
711 Added bend_start/bend_stop handlers for server. These handler are
712 called on start/stop of server. For windows they are called whenever
713 a service is started/stopped.
715 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
716 a fairly small ASN.1 compiler written in Tcl. The compiler is located
717 in util/yc.tcl. The auto-generated C code structures are, in a few
718 cases, incompatible with the old decoders. There are differences in the
719 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
720 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
721 The preprocessor variable ASN_COMPILED is defined when the compiled
722 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
723 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
724 wish to use the old encoders/decoders you can specify --disable-yc
727 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
728 version so that it supports both new - and old version of DB Update
730 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
731 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
732 change. The name parameter can be set to 0 in which no name is specified
733 for the construction. The macros odr_implicit and odr_explicit sets name
734 parameter to zero for the construction involved. New macros
735 odr_implicit_tag and odr_explicit_tag are similar to the others,
736 except that a name parameter is added. For programmers' that don't use
737 ODR they probably only need to change the call to z_APDU and z_External.
739 Added access control facility by interfacing the TCP wrapper library.
740 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
741 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
742 name of the daemon and enables the access control as specified in
743 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
745 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
746 den Dool <H.M.vdnDool@kub.nl>.
748 Added reference ID parameter to most functions in server API - refer
749 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
751 Changed name of ccl library to libccl.a (was ccl.a).
753 Fixed bug in decoder for Explain (Category TargetInfo).
755 Added support for GNU readline in client. Thanks to Jacob Poulsen
756 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
758 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
759 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
760 IMPLEMENTATION! This change was made to the development version before
761 the ZIG decided to retract the amendment. If any users MUST be
762 compatible with the original Update definition, PLEASE CONTACT US, and
763 we will include a separate definition corresponding to the old Update
764 ES. Note that because of the change to the ASN.1 of the
765 TaskPackageRecordStructure we cannot define a single structure that
766 will support both versions.
768 * Added const modifier to buffer parameter for some ODR/BER encoding
769 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
770 completeWAIS, odr_dumpBER.
772 Fixed bug in client.c which caused a crash when a scanResponse didn't
773 contain positionOfTerm.
775 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
776 * will cause an error in a client if a non-YAZ target sends both a
777 * list of Scan entries and non-surrogate diagnostics.
779 Retrieval module enhancements. Tag sets may be typed in the reference
780 to it. From the .abs-file the "tagset" directive takes a third optional
781 integer type for the tag set referenced. From a .tag-file the "include"
782 directive takes a third optional type as well. The old "type" directive
783 in the tag set itself is still recognized but acts as the default type
786 Backend interface change. Individual Scan terms returned from bend_scan
787 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
788 in include/backend.h.
790 Retrieval module enhancements. Multiple tag sets and attribute sets may
791 be specified in abstract syntax specs. Revised the error/warning for
792 logging messages reported by the retrieval module when reading the
795 Object Identifier system (oid_..) changed. The API is backwards
796 compatible but the oid-routines now allocates new OID's when needed.
797 Raw OID's may be specified in oid_getvalbyname.
799 YAZ now uses GNU configure to generate Makefile(s).
801 * Minor changes in some of the member names of DeleteResultSetRequest and
802 DeleteResultSetResponse. See include/proto.h.
804 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
805 and added member 'languages' in TargetInfo (which was missing).
807 Changed the way attribute sets are handled in the retrieval
808 module. These are now cached, just like the abstract syntaxes
811 Changed YAZ so that it links with compiled ASN.1.
813 Added Explain-schema definitions and mapping routines. The following
814 Explain categories have been implemented: AttributeDetails,
815 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
817 Fixed minor bug in Windows version of Server Library.
819 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
821 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
823 Added EXTERNAL: UNIverse Resource Report (non-standard).
825 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
826 ENUMERATED and SET OF.
828 * Added 'const' to some of the char pointer arguments for the
829 functions, data1_read_node, data1_getelementbytagname,
830 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
833 Fixed bug in data1_insert_taggeddata - the last_child member of
834 parent wasn't initialised.
836 * Changed data1_read_record and data1_read_node so that the supplied
837 "SGML"-buffer is read-only. In particular the resulting data1 - tree
838 doesn't refer to any parts of the "SGML"-buffer.
840 Fixed bug in server library (Windows version of statserv_remove).
842 * Changed code so that it compiles as C++. The type definition
843 of Odr_fun which is a member of Odr_arm was changed. The result is,
844 that an explicit typecast is needed for the fun pointer when
845 using Odr_arm - as in:
846 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
848 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
850 Implemented the new structured date and time definition as approved
851 by the ZIG. Added schemaId element to the specificTag in Espec-1
852 (also approved at the last ZIG). Thanks to RVDM.
854 Added some Object identifiers (RVDM).
856 Changed the Update Extended Service (RVDM).
858 Added command "refid" to client which specifies referenceId for
859 the following requests.
861 Implemented extended service handling for server. See ztest.c
862 for an example as well as backend.h. New handlers are registerd
865 * Changed interface for sort in server.
867 Added new members to statserv_options_block. It allows a server
868 to read options from another source than just the command line. Thanks
869 to Charles Woodfield.
871 * Changed definition of Z_Triple in file prt-grs.h - member boolean
872 renamed to zboolean. Some C++ compilers complained about the name.
874 Minor changes to gils.abs. Added index 's' (sort) on title
875 and date/time-last-modified.
879 Fixed bug in server library regarding inetd mode (-i). This bug
880 was introduced by release 1.4.
884 Added sort facility in client and backend server interface.
886 Fixed problem with dependencies in Makefile(s).
888 Fixed bugs for encoders/decoders of extended services and
891 Implemented sub-tree feature for schemas. Sub-trees are
892 referenced in *.abs-files. See explain.abs for an example
893 of the use of this feature.
895 Modified bib1.att; local attributes for ANY didn't include
896 ANY itself (only affects use of the retrieval module).
898 Fixed bug in plain SGML reader in function data1_read_node:
899 tags with prefix "var" was incorrectly interpreted as variants.
901 Added feature "sub-schemas" to enable references to - and definitions
902 of - group of elements.
904 * Removed member parent from type data1_element (in data1.h).
906 Implemented function odr_nullval() that returns the value of
909 * Removed member num_children from data1_node (in data1.h).
911 Made NT service interface part of the server library. The
912 function statserv_main uses the NT service when required and
913 calls the statserv_start / statserv_close routines.
915 Routine zget_SearchRequest and zget_PresentRequest fills
916 resultSetName/Id member with "default" instead of "Default".
918 Fixed memory leak in server. Request queue member wasn't freed.
920 Fixed nmem_exit so that memory is freed.
924 Revised the CCL parser utility to be thread safe.
926 Added function, oid_ent_to_oid, to replace the function
927 oid_getoidbyent, which is not thread safe.
929 * Added nmem_init and nmem_exit to initialize and release
930 NMEM resources. Function nmem_init should be called once in the
931 initial thread before NMEM/ODR is used. statserv.c and client.c
932 have been changed accordingly. The change was necessary to make
933 NMEM thread safe. The NMEM memory pool is shared amongst threads
934 in a process. Unix-based applications will still work fine without
937 Added NT Services interface for the the Z39.50 (statserv) Server.
938 Refer to the ztest.c source on the usage.
940 Windows 95/NT port using MSVC5.0. Project files are included in the
943 * Defined new 'global' handle for the retrieval (data1) system. The
944 new handled, data1_handle, describes the state of the data1 system.
945 This handle is passed as first argument to virtually all
946 data1 related routines. The functions data1_create and data1_destroy
947 creates and destroys a data1 handle respectively.
949 Added ODR encode stream member to all backend request structures
950 init, search, scan etc. This stream should be used to allocate all
951 memory used for the response when thread safe operation is needed.
953 Changed the comstack utility, cs_addstr, to be thread safe. The
954 returned hostname string returned by the function is now part the
957 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
958 function. The cs_straddr takes a COMSTACK handle as argument, so this
959 function must be used after cs_create and before bind/connect.
960 This function is thread safe.
962 Moved test server to 'ztest' directory - generic server code still
963 in 'server' directory.
965 Made prefix query (pquery.c) utility thread safe.
967 Added new function modifier YAZ_EXPORT to 'export' public DLL
968 functions when using windows (see include/yconfig.h).
970 Added definitions to the OID database (util/oid.c) (RVDM).
972 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
974 Added call to ccl_rpn_delete in client program.
976 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
977 release of RPN structure.
979 Added support for C++, headers uses extern "C" for public definitions.
980 With input from RVDM.
982 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
983 Thanks to Ronald van der Meer (RVDM).
985 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
987 Added support for private extensions to the OID database
988 (oid_setprivateoids()). Thanks to RVDM.
990 Added optional, physical ANY (key replication)
992 Fixed null-reference problem in GRS-1 output filter.
994 Proximity operator added to Prefix Query Format (PQF).
996 In test client command "base" accepts multiple databases.
998 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1002 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1004 Smallish bug-fixes in the new encoders/decoders (explain).
1006 Bug fixed in DeleteRequest.
1008 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1010 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1012 Added SOIF syntax (using private OID for now) to retrieval module and client.
1014 Added Update extended service.
1016 Added SearchResult-1 additional info structure.
1018 Added optional CCL (ISO8777) interpreter as separate module. Available
1021 --- 1.2 1996/6/10 (1st anniversary release)
1023 Added Summary record syntax. Lightly tested.
1025 Added OPAC record syntax. Untested.
1027 Added ResourceReport service encoders/decoders. Untested.
1029 Fixed bug in z_Unit - wrong tagging on unitSystem.
1031 Fixed bug in the DiagRecs decoder.
1033 Added options for max PDU size and session timeout to frontend-server.
1035 Added documentation of query-language parsers and other supporting utilities.
1037 [frontend-server] Added Attribute set to the bend_scanrequest API.
1039 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1040 surrogate diagnostics were generated.
1042 [retrieval] Allow multiple local values for attribute.
1044 [retrieval] Allow multiple attributes per element in .abs files. index type.
1046 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1048 --- 1.1pl2 1996/4/10
1050 Minor changes, mostly specific to Zebra's requirements (retrieval)
1054 Repaired bug in frontend server when running multiple listening
1055 endpoints in dynamic mode.
1057 z_External() now won't break if a known, ASN.1 value comes encapsulated
1058 in an octet-string. The value will pass through unmodified in an Odr_oct.
1060 Added a bit of code to the demo client to decode & display
1061 ASN.1-structured records represented in the octet-aligned branch of
1062 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1064 Added z_ext_getentbyref() to the ASN module. Doc updated.
1066 * Completed the SCAN definition in the ASN module. This may break SCAN
1067 code based on older YAZ-versions at compile-time. The fix is easy -
1070 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1071 under the SCAN definition. Remember to initialize this, server-people.
1073 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1074 that this does not extend to ODR and ASN.
1076 Comstack allows insertion of established socket (primarily for
1077 inetd-operation of servers). Doc updated.
1079 Front-end server can now start from the inetd in TCP mode. Doc
1082 --- 1.0pl4 1996/1/24
1086 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1087 the rank and record number.
1089 Adjustments to the frontend server.
1091 Fixed diagnostic BER dumper. It ignored the file argument.
1095 Various changes to retrieval module.
1097 Changed the union discriminators of the protocol files from enums to
1098 ints paired with #defines.
1100 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1103 *Changed operator in the RPN structure to 'roperator', again to avoid a
1106 Fixed problems in Explain decoders/encoders.
1108 --- 1.0pl2 1995/12/6
1110 Memory bug in log module fixed.
1112 --- 1.0pl1 1995/12/5
1114 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1116 Bug in Explain DatabaseInfo module fixed.
1118 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1122 The shift to v1.0 signals that we now consider the *core* functionality
1123 of YAZ reasonably stable (the core being more or less equivalent to
1124 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1125 tested (Explain not at all - though that will happen soonish).
1127 Minor changes to code to support Windows port.
1129 Various minor changes after we're getting to use GRS-1 & co. more.
1131 Added Espec-1 format.
1133 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1134 of the protocol and it cannot be selected when encoding (maps into 'string'
1135 when decoding). Needed to talk to some servers.
1137 Demo client can request simple element set names.
1139 Added Diagnostic Format encoders/decoders.
1141 Added simple Close handling to frontend server (no hooks for resource
1142 reporting yet), and demonstration client.
1144 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1146 --- 1.0b3 1995/08/24
1148 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1149 handled incorrectly when records were requested in the searchResponse. This
1150 will only affect you if you use the frontend-server.
1152 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1153 Test-client will ask for and print GRS1. Ztest will return dummy records
1156 Added Explain encoders/decoders to the service-level API. Untested.
1158 Added Extended Services: Item Order encoders and decoders to the Service-
1159 level API. Untested. We could use a recent copy of the pertinent bits
1160 of the ILL protocol to add those bits.
1162 Added diagnostic format 1 encoders/decoders to the service-level API.
1165 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1166 odr_cons.c, which causes a more correct output.
1168 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1169 was always set to 0 when no records were requested in the searchRequest.
1171 * Added better external-handling. This shouldn't harm old code that
1172 *encodes* externals. It can break code that looks for a
1173 'single-ASN1-type' representation, since those types that are known
1174 are now decoded immediately. Look at the SUTRS sample code in
1175 seshigh.c and client.c. Documentation updated.
1177 Handling of structured records in bend_fetchresponse. Length -1 marks
1178 structured record, type is deduced from format field.
1180 --- 1.0b2 1995/06/27
1181 Fairly quick maintenance release to add SUTRS support.
1183 Fixed handling of SUTRS records in the demonstration client.
1185 * Added format field to the bend_fetchrequest and bend_fetchresponce
1186 structures of the backend API (frontend server). When the record is
1187 returned, the value of the format field is mapped to an OID. The
1188 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1189 of the record. The special value VAL_NONE in the bend_request means
1190 that no specific format was requested by the client. Documentation
1191 updated accordingly. Test server (ztest) will return a fixed dummy
1192 SUTRS record if your client requests SUTRS.
1194 Documentation updated accordingly.
1196 You can now set external libraries and RANLIB support in the top-level
1200 First public release.
