1 Possible compatibility problems with earlier versions marked with '*'.
3 Add three new utility functions for translating OIDs between various
4 formats -- symbolic name such as "Usmarc", minus-1-terminated int
5 arrays and dotted strings such as "1.2.840.10003.9.5.1":
6 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
7 char *oid_to_dotstring(const int *oid, char *oidbuf);
8 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
10 Reverted modifications for ES Update definition for z_IU0Update
11 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
14 String value attributes for CCL parser.
18 Fix CCL directive @case handling so that it affects string match for
19 both CCL keywords and qualifiers.
21 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
22 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
23 Decoder has been updated with ASN.1 changes as listed in
24 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
25 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
26 z_IUUpdate, remains unchanged.
28 ZOOM_record_get may now return a record in a specific character set.
29 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
30 "from" is the character set of record as returned by target. "to" is
31 the character set to be returned. If omitted, "to" is UTF-8.
33 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
35 New ODR utility, odr_getelement, which returns name of element for
36 which encoding/decoding failed.
38 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
39 in cases where a required element was omitted.
41 Bug fix: some MARC8 sequences were not converted.
43 New ZOOM option "step" which specifies number of records to be
44 retrieved in one chunk. Used in conjunction with "start" and "count".
46 SRW support for yaz-client. Use scheme http: to use it, e.g.
49 yaz-client no longer does (un)intelligent character set conversions
50 by default. Can be enabled with charset and marc_charset commands.
52 xmalloc trace fix for 64-bit systems such as DEC alpha.
54 Solaris 2.6 compile fix.
56 New function, cql_strerror() translates SRW error codes, as returned
57 by cql_transform_error(), into human-readable English strings. Used
58 in yaz-client diagnostics when appropriate.
60 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
61 converts it into a type-1 query which is sent to the server. This
62 makes CQL available for use with all Z-servers, as opposed to the tiny
63 minority that can handle CQL queries themselves.
67 New Debian package layout similar to the Redhat Package layout.
69 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
70 and search result respectively.
74 Redhat package is now several packages: libyaz (runtime libraries),
75 libyaz-devel (development and documentation, and yaz (utility programs).
76 Package spec file by Morten Bøgeskov.
78 New member 'schema' in struct bend_fetch_rr which the name of requested
79 schema (SRW/SRU) for record (or NULL if none was given). The fetch
80 handler MAY set this to reflect the schema of the returned record.
82 New member 'display_term' in struct scan_entry. GFS now sets member entries
83 and allocates scan entries to be filled by user scan handler. In previous
84 version, entries member was allocated by the scan handler. That still works,
85 but the GFS will ignore member display_term - assuming it was NOT set by
86 the handler. The fact that the GFS now allocates the entries both allows
87 for new members and makes a scan handler easier to write.
89 Fix CQL lex buffer overflow.
91 SRW/SRU recordPacking. For SRW default recordPacking is string. For
92 SRU default recordPacking is string.
94 SRU protocol support for frontend server.
96 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
98 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
100 Added scan for the ZOOM shell (zoomsh).
104 * String Identifers for Schemas (Amendment 5).
105 http://lcweb.loc.gov/z3950/agency/amend/am5.html
106 Old definition for schema
107 Odr_oid *schema; /* OPT */
112 Z_InternationalString *uri;
113 #define Z_Schema_oid 1
114 #define Z_Schema_uri 2
117 * resultCount parameter to Sort Response (Amendment 1).
118 http://lcweb.loc.gov/z3950/agency/amend/am1.html
120 Support for SRW 1.0 over HTTP. This is an optional feature and
121 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
124 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
125 on the same port. SRW SearchRetrieveRequests are mapped
126 to bend_init,bend_search,bend_fetch,bend_close.
128 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
130 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
131 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
133 ZOOM connections are SRW based if schem http is used for hostname
134 in connect, e.g. z = ZOOM_connection_new("http://myserver");
135 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
137 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
138 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
139 distance=n, order=true/false, relation=le, prox unit=word. If
140 n is omitted, distance 1 is used.
142 Fixed problem with C compiler include path in wrong order.
144 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
145 on Solaris. Patch from Ko van der Sloot.
147 New MARC decode API. All new functions operate on a yaz_marc_t
148 handle. The most important new functions are: yaz_marc_create,
149 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
150 decode and destroy respectively. Decoder can produce formats
151 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
152 include/yaz/marcdisp.h.
154 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
155 to UTF-8, UCS-32, wchar_t or Latin-1.
157 * Prototypes for yaz_iconv_-functions moved to separate header
158 include/yaz/yaz-iconv.h.
160 Make a few private functions 'static' in unix.c. This prevents
161 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
163 For ZOOM connection, the options targetImplementation{Id,Name,Version}
164 are set when Init Response is received.
166 New function ZOOM_connection_error_x similar to ZOOM_connection_error
167 but returns diagnostic set as well.
169 New function yaz_strerror which is a portable wrapper for
170 strerror/strerror_r/GetLastMessage.
172 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
173 is returned for MARC. If type is "oai", then OAI MARC is returned.
175 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
180 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
182 Fix bad race conditions on SIGTERM and terminate gracefully in
185 Move retrieval (data1) module to Zebra since nobody seems to be
188 Add GRS-1 render for ZOOM using same format as yaz-client.
192 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
194 Fix broken ESpec handling in data1 module.
196 SGML reader parses comments and makes them part of the data1 tree.
198 Added several type casts so that YAZ compiles as C++ code.
200 ZOOM didn't handle PDU encoding failures properly.
202 Added more Bib-1 diagnostics (approved extensions).
204 GNU configure: better check for iconv.
206 More portable use of accept, getpeername. Check for socklen_t. Use
207 int/size_t if socklen_t is not defined.
211 PQF parser rejects bad queries - including those with extra
212 characters in them. PQF parser used to silently ignore that.
213 Cleaner API for PQF added, which allows you to get detailed
214 error information for bad queries (see yaz/pquery.h).
216 Fixed bug in ZOOM_record_get for type "database".
218 Implemented mini iconv library supporting conversions between
219 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
221 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
225 Fixed ZOOM C record cache so that preferredRecordSyntax and
226 elementSetName is used to check for already fetched records.
230 Added three members in bend_initrequest structure to facilitate
231 character set negotiation.
233 Fixed a bug in frontend server that could cause indefinite
234 loops under rare conditions.
236 Revised character set utilities (charneg.h) so that encoding
237 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
239 For PQF, directive @term <type> sets term type for Scan/Search.
240 Here <type> is general, string, numeric, null. The term type
241 is inherited - just like @attr.
243 New call odr_set_charset that sets character set conversion for
244 international-strings on a ODR stream. Prototype is:
245 int odr_set_charset(ODR o, const char *to, const char *from);
246 The InternationalString is still represented as C string in YAZ
247 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
248 won't). On the protocol level, you can use any encoding.
250 Support for UNIX sockets in ZOOM.
252 Solaris recv sometimes returns errno == ENOENT. It is treated as
253 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
255 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
256 both client and server. Code by Morten Bøgeskov.
260 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
261 that they can be used directly from Visual Basic. You must recompile
262 your windows APP if you're using ZOOM.
264 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
265 Commands "lang" and "charset" sets language and character set respectively.
266 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
267 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
269 Attributes from multiple CCL fields may be OR'ed rather than merged
270 using directive "@field or". Fields are still merged by default -
271 equivalent to "@field merge".
273 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
276 Fixed bug in zget for parameter ExtendedServicesResponse.
282 Added PQF feature: '@attr type=value' may be written as '@type=value'.
284 Client displays USR.1:SearchResult-1 (hits per term).
286 Additional Search Info for search in Generic Frontend Server.
288 Fixed CCL parsing of "field=s".
290 WIN32 installer - using the excellent NSIS software from nullsoft.
292 Fixed CCL parsing of "field = - <number>".
294 Added function yaz_marc_decode that decodes MARC for line mode
295 display or XML (similar to that used by JZKit).
297 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
298 Z39.50. But ISO/ILL was, however.
300 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
301 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
303 http://lcweb.loc.gov/z3950/agency/amend/am2.html
304 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
308 New YAZ client features: Command completion and new commands:
309 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
310 Code provided by Jacob Poulsen.
312 New call oid_trav, that visits all registered OIDs via callback.
314 Function ZOOM_record_get now returns const char pointer rather than
315 void pointer. It saves a lot of type casts.
317 For YAZ client, command "auth" now allows you to set authentication
318 in IdPass style. It is enabled when three tokens are given - order
319 is user, group and password.
321 Fix memory leaks in MARC record handling for ZOOM.
323 New option for YAZ client, -k <kilobytes> that sets
324 maximum record size. Similar to -k option for generic frontend
325 server and yaz-ztest.
327 More fixes for scan. Non-zero stepSize handled. OID's fixes.
329 Prefix query parser reports "fail" when bad attribute set is given.
331 Fix in MARC decoder. Proximity logging. Fix for attribute set
332 in scan handler for server. Patches by Shigeru Ishida.
334 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
337 Configure option --with-openssl=<dir> now works when a directory is
338 specified. Patch provided by Morten Bøgeskov.
340 New option for YAZ client, -u <auth>, that sets authentication.
342 ZOOM fix: error information was sometimes "missing", since error
343 was cleared/reset too when it shouldn't.
345 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
349 Scan for ZOOM API. New object ZOOM_scanset. New functions
350 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
351 ZOOM_scanset_destroy.
353 New ZOOM function, ZOOM_connection_last_event, that returns type
354 of last event (such as "receive data", "send data", "apdu received",
357 New ZOOM option, schema, that specifies schema for retrieval.
359 New CCL feature. Qualifiers can be aliases for one or more
360 other qualifiers (if more than one is given, OR is used).
362 ZOOM uses named result sets if target supports it.
364 Two new YAZ client commands: . (dot, which sources a script of YAZ
365 client commands), and ! (to execute shell command.). Implemented
368 Working on Debian packages.
372 YAZ client enables named result sets only if target supports it.
374 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
376 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
377 with key="host" to get same result.
379 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
380 Function Z3950_resultset_record(s) returns references to records
381 "owned" by resultset. To become owner use Z3950_record_clone.
383 Function z_ext_record handles Extended Services. Thanks to
388 CCL Parser fix: ignore token comma when dealing with and-lists.
390 Documentation updates for COMSTACK.
392 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
393 Changed prototype Z3950_records. For some functions, int parameters
394 were changed to size_t.
396 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
399 New MARC decode/display function, marc_display_exl, which properly rejects
400 non-ISO2709 records. YAZ client uses it.
404 Fix bug: local attribute set wasn't set correctly in PQF strings.
408 * Old Z39.50 codecs no longer supported.
410 Added ZOOM C binding. See http://zoom.z3950.org/
412 Renamed states for COMSTACKs to avoid confusion with events.
414 Implemented cs_look and proper cs_rcvconnect.
416 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
418 Configure detects POSIX threads on OpenBSD.
420 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
421 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
423 When error is returned from present handler, non-surrogate diagnostic
424 is returned in present response (and fetch handler is no longer called).
426 * Minor adjustments to pquery parser (PQF). Token characters may be
427 escaped by using backslash (C-style).
429 PQF parser allows string attribute values to be specified. For @attr,
430 non-numeric characters after the equal-sign are treated as strings
431 (e.g. @attr 9=title).
433 CCL trunction character may be defined (@truncation in file)
435 * function zget_ExtendedServicesRequest sets waitAction to
436 waitIfPossible (was wait).
438 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
441 CCL operator names may be set in field definition files (CCL_bibset).
442 See ccl/bib1 for an example.
444 Fixes in ASN.1 compiler for C++ compatibility.
446 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
447 and "op_or" to avoid conflict with C++.
449 Fixed problem with GNU readline detection on Redhat 7.0.
451 Added step-size for Scan backend handler.
453 Fixed bug that made the frontend server crash when no attribute
454 set was specified for scan.
456 Front-end server automatically switches to original working directory
457 when installed as an NT service. Previously -w had to be specified to
460 Added extended attributes for retrieval module (data1), so that data1
461 records carry d1_readXML/SGML attributes. d1_read also supports
462 null-data rules ( <tag/>)
464 On UNIX when POSIX threads are available, a separate library libyazthread
465 is created. Programmers should link with that library and the yaz library
466 when using threads. The reason for the split was that some applications
467 on Linux, such as Apache, doesn't work well when using shared objects that
470 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
471 (or any frontend server) in SSL mode by specifying ssl: followed by
472 address. Only tested on UNIX.
474 Added feature for CCL module. Virtual structure s=al or s=ol generates
475 and-list and or-list respectively instead of phrase search.
479 * Added prefix "yaz_" for the functions log_init.., log_file.. and
480 log_mask_str. This was done to avoid name conflicts with other libraries
481 (such as other PHP extensions).
483 Added raw OID member for preferred record syntax (request_format_raw)
484 and returned record syntax (output_format_raw) for backend fetch method.
486 Config file yaz-config now accepts options so that it returns specific
487 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
489 Shared library support for UNIX using GNU libtool.
491 * Modified backend interface. Request/Response struct's replaced by
492 one read/write C struct. For example bend_fetchrequest and
493 bend_fetchresult have been replaced by single bend_fetch_rr struct.
494 Every handler - even search has to be registered in bend_init
495 handler. This means that the YAZ library no longer refers to
496 external functions and it makes it possible to make the whole
497 thing a single DLL/SO.
499 Added Segment handler for backend server.
501 Added Zmbol/Zebra administrative functions to YAZ client.
503 Threaded frontend server on UNIX (when POSIX Threads are available).
504 Starting the server with option -T enables multi-threading.
508 Added configure option --enable-comp/disable-comp to control use
509 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
510 located in sub directory asn.
512 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
513 in ${exec_prefix}/bin along with the other programs yaz-client and
516 GNU automake used to maintain makefiles.
520 Changed retrieval module so that we can load records with no abstract
521 syntax defined. Tagpaths in these records are fully composed of string
524 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
528 On UNIX, the generated makefile now supports a proper 'make install'.
529 The prefix can be set via GNU configure to set the install location
530 (default is /usr/local).
532 * YAZ programs client and ztest were renamed to yaz-client and
533 yaz-ztest to avoid conflicts when users install YAZ in "standard"
534 locations, such as /usr/bin,/usr/local/bin,etc.
536 * YAZ Header files were moved from include to include/yaz. YAZ Header
537 files are referred to as include <yaz/log.h> rather than <log.h>.
538 The YAZ include path (-I ..) is therefore the same as before. Programmers
539 should update their #include statements or use -Ipath/include/yaz
540 instead. The main motivation for doing this change is that YAZ header files
541 can be installed in "standard" locations /usr/include,/usr/local/include
542 without introducing conflicts, since ALL YAZ header files are stored
543 in subdirectory yaz (under /usr/include for example).
545 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
546 rather than project/workspace files. We switched because project files
547 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
550 Changed name of logging function, logf, to yaz_log, to prevent name
551 clash with some math-log functions. The YAZ header log.h defines logf
552 to yaz_log (#define) so there should be no incompatibilities by this
555 Added bend_start/bend_stop handlers for server. These handler are
556 called on start/stop of server. For windows they are called whenever
557 a service is started/stopped.
559 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
560 a fairly small ASN.1 compiler written in Tcl. The compiler is located
561 in util/yc.tcl. The auto-generated C code structures are, in a few
562 cases, incompatible with the old decoders. There are differences in the
563 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
564 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
565 The preprocessor variable ASN_COMPILED is defined when the compiled
566 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
567 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
568 wish to use the old encoders/decoders you can specify --disable-yc
571 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
572 version so that it supports both new - and old version of DB Update
574 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
575 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
576 change. The name parameter can be set to 0 in which no name is specified
577 for the construction. The macros odr_implicit and odr_explicit sets name
578 parameter to zero for the construction involved. New macros
579 odr_implicit_tag and odr_explicit_tag are similar to the others,
580 except that a name parameter is added. For programmers' that don't use
581 ODR they probably only need to change the call to z_APDU and z_External.
583 Added access control facility by interfacing the TCP wrapper library.
584 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
585 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
586 name of the daemon and enables the access control as specified in
587 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
589 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
590 den Dool <H.M.vdnDool@kub.nl>.
592 Added reference ID parameter to most functions in server API - refer
593 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
595 Changed name of ccl library to libccl.a (was ccl.a).
597 Fixed bug in decoder for Explain (Category TargetInfo).
599 Added support for GNU readline in client. Thanks to Jacob Poulsen
600 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
602 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
603 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
604 IMPLEMENTATION! This change was made to the development version before
605 the ZIG decided to retract the amendment. If any users MUST be
606 compatible with the original Update definition, PLEASE CONTACT US, and
607 we will include a separate definition corresponding to the old Update
608 ES. Note that because of the change to the ASN.1 of the
609 TaskPackageRecordStructure we cannot define a single structure that
610 will support both versions.
612 * Added const modifier to buffer parameter for some ODR/BER encoding
613 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
614 completeWAIS, odr_dumpBER.
616 Fixed bug in client.c which caused a crash when a scanResponse didn't
617 contain positionOfTerm.
619 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
620 * will cause an error in a client if a non-YAZ target sends both a
621 * list of Scan entries and non-surrogate diagnostics.
623 Retrieval module enhancements. Tag sets may be typed in the reference
624 to it. From the .abs-file the "tagset" directive takes a third optional
625 integer type for the tag set referenced. From a .tag-file the "include"
626 directive takes a third optional type as well. The old "type" directive
627 in the tag set itself is still recognized but acts as the default type
630 Backend interface change. Individual Scan terms returned from bend_scan
631 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
632 in include/backend.h.
634 Retrieval module enhancements. Multiple tag sets and attribute sets may
635 be specified in abstract syntax specs. Revised the error/warning for
636 logging messages reported by the retrieval module when reading the
639 Object Identifier system (oid_..) changed. The API is backwards
640 compatible but the oid-routines now allocates new OID's when needed.
641 Raw OID's may be specified in oid_getvalbyname.
643 YAZ now uses GNU configure to generate Makefile(s).
645 * Minor changes in some of the member names of DeleteResultSetRequest and
646 DeleteResultSetResponse. See include/proto.h.
648 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
649 and added member 'languages' in TargetInfo (which was missing).
651 Changed the way attribute sets are handled in the retrieval
652 module. These are now cached, just like the abstract syntaxes
655 Changed YAZ so that it links with compiled ASN.1.
657 Added Explain-schema definitions and mapping routines. The following
658 Explain categories have been implemented: AttributeDetails,
659 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
661 Fixed minor bug in Windows version of Server Library.
663 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
665 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
667 Added EXTERNAL: UNIverse Resource Report (non-standard).
669 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
670 ENUMERATED and SET OF.
672 * Added 'const' to some of the char pointer arguments for the
673 functions, data1_read_node, data1_getelementbytagname,
674 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
677 Fixed bug in data1_insert_taggeddata - the last_child member of
678 parent wasn't initialised.
680 * Changed data1_read_record and data1_read_node so that the supplied
681 "SGML"-buffer is read-only. In particular the resulting data1 - tree
682 doesn't refer to any parts of the "SGML"-buffer.
684 Fixed bug in server library (Windows version of statserv_remove).
686 * Changed code so that it compiles as C++. The type definition
687 of Odr_fun which is a member of Odr_arm was changed. The result is,
688 that an explicit typecast is needed for the fun pointer when
689 using Odr_arm - as in:
690 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
692 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
694 Implemented the new structured date and time definition as approved
695 by the ZIG. Added schemaId element to the specificTag in Espec-1
696 (also approved at the last ZIG). Thanks to RVDM.
698 Added some Object identifiers (RVDM).
700 Changed the Update Extended Service (RVDM).
702 Added command "refid" to client which specifies referenceId for
703 the following requests.
705 Implemented extended service handling for server. See ztest.c
706 for an example as well as backend.h. New handlers are registerd
709 * Changed interface for sort in server.
711 Added new members to statserv_options_block. It allows a server
712 to read options from another source than just the command line. Thanks
713 to Charles Woodfield.
715 * Changed definition of Z_Triple in file prt-grs.h - member boolean
716 renamed to zboolean. Some C++ compilers complained about the name.
718 Minor changes to gils.abs. Added index 's' (sort) on title
719 and date/time-last-modified.
723 Fixed bug in server library regarding inetd mode (-i). This bug
724 was introduced by release 1.4.
728 Added sort facility in client and backend server interface.
730 Fixed problem with dependencies in Makefile(s).
732 Fixed bugs for encoders/decoders of extended services and
735 Implemented sub-tree feature for schemas. Sub-trees are
736 referenced in *.abs-files. See explain.abs for an example
737 of the use of this feature.
739 Modified bib1.att; local attributes for ANY didn't include
740 ANY itself (only affects use of the retrieval module).
742 Fixed bug in plain SGML reader in function data1_read_node:
743 tags with prefix "var" was incorrectly interpreted as variants.
745 Added feature "sub-schemas" to enable references to - and definitions
746 of - group of elements.
748 * Removed member parent from type data1_element (in data1.h).
750 Implemented function odr_nullval() that returns the value of
753 * Removed member num_children from data1_node (in data1.h).
755 Made NT service interface part of the server library. The
756 function statserv_main uses the NT service when required and
757 calls the statserv_start / statserv_close routines.
759 Routine zget_SearchRequest and zget_PresentRequest fills
760 resultSetName/Id member with "default" instead of "Default".
762 Fixed memory leak in server. Request queue member wasn't freed.
764 Fixed nmem_exit so that memory is freed.
768 Revised the CCL parser utility to be thread safe.
770 Added function, oid_ent_to_oid, to replace the function
771 oid_getoidbyent, which is not thread safe.
773 * Added nmem_init and nmem_exit to initialize and release
774 NMEM resources. Function nmem_init should be called once in the
775 initial thread before NMEM/ODR is used. statserv.c and client.c
776 have been changed accordingly. The change was necessary to make
777 NMEM thread safe. The NMEM memory pool is shared amongst threads
778 in a process. Unix-based applications will still work fine without
781 Added NT Services interface for the the Z39.50 (statserv) Server.
782 Refer to the ztest.c source on the usage.
784 Windows 95/NT port using MSVC5.0. Project files are included in the
787 * Defined new 'global' handle for the retrieval (data1) system. The
788 new handled, data1_handle, describes the state of the data1 system.
789 This handle is passed as first argument to virtually all
790 data1 related routines. The functions data1_create and data1_destroy
791 creates and destroys a data1 handle respectively.
793 Added ODR encode stream member to all backend request structures
794 init, search, scan etc. This stream should be used to allocate all
795 memory used for the response when thread safe operation is needed.
797 Changed the comstack utility, cs_addstr, to be thread safe. The
798 returned hostname string returned by the function is now part the
801 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
802 function. The cs_straddr takes a COMSTACK handle as argument, so this
803 function must be used after cs_create and before bind/connect.
804 This function is thread safe.
806 Moved test server to 'ztest' directory - generic server code still
807 in 'server' directory.
809 Made prefix query (pquery.c) utility thread safe.
811 Added new function modifier YAZ_EXPORT to 'export' public DLL
812 functions when using windows (see include/yconfig.h).
814 Added definitions to the OID database (util/oid.c) (RVDM).
816 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
818 Added call to ccl_rpn_delete in client program.
820 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
821 release of RPN structure.
823 Added support for C++, headers uses extern "C" for public definitions.
824 With input from RVDM.
826 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
827 Thanks to Ronald van der Meer (RVDM).
829 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
831 Added support for private extensions to the OID database
832 (oid_setprivateoids()). Thanks to RVDM.
834 Added optional, physical ANY (key replication)
836 Fixed null-reference problem in GRS-1 output filter.
838 Proximity operator added to Prefix Query Format (PQF).
840 In test client command "base" accepts multiple databases.
842 Fixed bug in cs_close stack that caused trouble with WINSOCK.
846 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
848 Smallish bug-fixes in the new encoders/decoders (explain).
850 Bug fixed in DeleteRequest.
852 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
854 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
856 Added SOIF syntax (using private OID for now) to retrieval module and client.
858 Added Update extended service.
860 Added SearchResult-1 additional info structure.
862 Added optional CCL (ISO8777) interpreter as separate module. Available
865 --- 1.2 1996/6/10 (1st anniversary release)
867 Added Summary record syntax. Lightly tested.
869 Added OPAC record syntax. Untested.
871 Added ResourceReport service encoders/decoders. Untested.
873 Fixed bug in z_Unit - wrong tagging on unitSystem.
875 Fixed bug in the DiagRecs decoder.
877 Added options for max PDU size and session timeout to frontend-server.
879 Added documentation of query-language parsers and other supporting utilities.
881 [frontend-server] Added Attribute set to the bend_scanrequest API.
883 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
884 surrogate diagnostics were generated.
886 [retrieval] Allow multiple local values for attribute.
888 [retrieval] Allow multiple attributes per element in .abs files. index type.
890 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
894 Minor changes, mostly specific to Zebra's requirements (retrieval)
898 Repaired bug in frontend server when running multiple listening
899 endpoints in dynamic mode.
901 z_External() now won't break if a known, ASN.1 value comes encapsulated
902 in an octet-string. The value will pass through unmodified in an Odr_oct.
904 Added a bit of code to the demo client to decode & display
905 ASN.1-structured records represented in the octet-aligned branch of
906 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
908 Added z_ext_getentbyref() to the ASN module. Doc updated.
910 * Completed the SCAN definition in the ASN module. This may break SCAN
911 code based on older YAZ-versions at compile-time. The fix is easy -
914 * Added 'displayTerm' and OtherInformation to the TermInfo structure
915 under the SCAN definition. Remember to initialize this, server-people.
917 Comstack should now support the WAIS protocol in TCP/IP mode. Note
918 that this does not extend to ODR and ASN.
920 Comstack allows insertion of established socket (primarily for
921 inetd-operation of servers). Doc updated.
923 Front-end server can now start from the inetd in TCP mode. Doc
930 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
931 the rank and record number.
933 Adjustments to the frontend server.
935 Fixed diagnostic BER dumper. It ignored the file argument.
939 Various changes to retrieval module.
941 Changed the union discriminators of the protocol files from enums to
942 ints paired with #defines.
944 *Changed oident.class to oident.oclass to avoid a reserved word in C++
947 *Changed operator in the RPN structure to 'roperator', again to avoid a
950 Fixed problems in Explain decoders/encoders.
954 Memory bug in log module fixed.
958 Occasional malloc() of 0 bytes fixed in d1_espec.c.
960 Bug in Explain DatabaseInfo module fixed.
962 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
966 The shift to v1.0 signals that we now consider the *core* functionality
967 of YAZ reasonably stable (the core being more or less equivalent to
968 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
969 tested (Explain not at all - though that will happen soonish).
971 Minor changes to code to support Windows port.
973 Various minor changes after we're getting to use GRS-1 & co. more.
975 Added Espec-1 format.
977 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
978 of the protocol and it cannot be selected when encoding (maps into 'string'
979 when decoding). Needed to talk to some servers.
981 Demo client can request simple element set names.
983 Added Diagnostic Format encoders/decoders.
985 Added simple Close handling to frontend server (no hooks for resource
986 reporting yet), and demonstration client.
988 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
992 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
993 handled incorrectly when records were requested in the searchResponse. This
994 will only affect you if you use the frontend-server.
996 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
997 Test-client will ask for and print GRS1. Ztest will return dummy records
1000 Added Explain encoders/decoders to the service-level API. Untested.
1002 Added Extended Services: Item Order encoders and decoders to the Service-
1003 level API. Untested. We could use a recent copy of the pertinent bits
1004 of the ILL protocol to add those bits.
1006 Added diagnostic format 1 encoders/decoders to the service-level API.
1009 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1010 odr_cons.c, which causes a more correct output.
1012 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1013 was always set to 0 when no records were requested in the searchRequest.
1015 * Added better external-handling. This shouldn't harm old code that
1016 *encodes* externals. It can break code that looks for a
1017 'single-ASN1-type' representation, since those types that are known
1018 are now decoded immediately. Look at the SUTRS sample code in
1019 seshigh.c and client.c. Documentation updated.
1021 Handling of structured records in bend_fetchresponse. Length -1 marks
1022 structured record, type is deduced from format field.
1024 --- 1.0b2 1995/06/27
1025 Fairly quick maintenance release to add SUTRS support.
1027 Fixed handling of SUTRS records in the demonstration client.
1029 * Added format field to the bend_fetchrequest and bend_fetchresponce
1030 structures of the backend API (frontend server). When the record is
1031 returned, the value of the format field is mapped to an OID. The
1032 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1033 of the record. The special value VAL_NONE in the bend_request means
1034 that no specific format was requested by the client. Documentation
1035 updated accordingly. Test server (ztest) will return a fixed dummy
1036 SUTRS record if your client requests SUTRS.
1038 Documentation updated accordingly.
1040 You can now set external libraries and RANLIB support in the top-level
1044 First public release.
