1 Possible compatibility problems with earlier versions marked with '*'.
3 New ZOOM setting, recordCharset, with value "from[,to]"
4 where from is the character set of a record as received
5 by the target. The character set "to" is desired charset
6 of output record as returned by ZOOM_record_get. If
7 "to" is omitted, UTF-8 is assumed.
9 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
11 New ODR utility, odr_getelement, which returns name of element for
12 which encoding/decoding failed.
14 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
15 in cases where a required element was omitted.
17 Bug fix: some MARC8 sequences were not converted.
19 New ZOOM option "step" which specifies number of records to be
20 retrieved in one chunk. Used in conjunction with "start" and "count".
22 SRW support for yaz-client. Use scheme http: to use it, e.g.
25 yaz-client no longer does (un)intelligent character set conversions
26 by default. Can be enabled with charset and marc_charset commands.
28 xmalloc trace fix for 64-bit systems such as DEC alpha.
30 Solaris 2.6 compile fix.
32 New function, cql_strerror() translates SRW error codes, as returned
33 by cql_transform_error(), into human-readable English strings. Used
34 in yaz-client diagnostics when appropriate.
36 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
37 converts it into a type-1 query which is sent to the server. This
38 makes CQL available for use with all Z-servers, as opposed to the tiny
39 minority that can handle CQL queries themselves.
43 New Debian package layout similar to the Redhat Package layout.
45 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
46 and search result respectively.
50 Redhat package is now several packages: libyaz (runtime libraries),
51 libyaz-devel (development and documentation, and yaz (utility programs).
52 Package spec file by Morten Bøgeskov.
54 New member 'schema' in struct bend_fetch_rr which the name of requested
55 schema (SRW/SRU) for record (or NULL if none was given). The fetch
56 handler MAY set this to reflect the schema of the returned record.
58 New member 'display_term' in struct scan_entry. GFS now sets member entries
59 and allocates scan entries to be filled by user scan handler. In previous
60 version, entries member was allocated by the scan handler. That still works,
61 but the GFS will ignore member display_term - assuming it was NOT set by
62 the handler. The fact that the GFS now allocates the entries both allows
63 for new members and makes a scan handler easier to write.
65 Fix CQL lex buffer overflow.
67 SRW/SRU recordPacking. For SRW default recordPacking is string. For
68 SRU default recordPacking is string.
70 SRU protocol support for frontend server.
72 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
74 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
76 Added scan for the ZOOM shell (zoomsh).
80 * String Identifers for Schemas (Amendment 5).
81 http://lcweb.loc.gov/z3950/agency/amend/am5.html
82 Old definition for schema
83 Odr_oid *schema; /* OPT */
88 Z_InternationalString *uri;
89 #define Z_Schema_oid 1
90 #define Z_Schema_uri 2
93 * resultCount parameter to Sort Response (Amendment 1).
94 http://lcweb.loc.gov/z3950/agency/amend/am1.html
96 Support for SRW 1.0 over HTTP. This is an optional feature and
97 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
100 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
101 on the same port. SRW SearchRetrieveRequests are mapped
102 to bend_init,bend_search,bend_fetch,bend_close.
104 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
106 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
107 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
109 ZOOM connections are SRW based if schem http is used for hostname
110 in connect, e.g. z = ZOOM_connection_new("http://myserver");
111 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
113 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
114 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
115 distance=n, order=true/false, relation=le, prox unit=word. If
116 n is omitted, distance 1 is used.
118 Fixed problem with C compiler include path in wrong order.
120 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
121 on Solaris. Patch from Ko van der Sloot.
123 New MARC decode API. All new functions operate on a yaz_marc_t
124 handle. The most important new functions are: yaz_marc_create,
125 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
126 decode and destroy respectively. Decoder can produce formats
127 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
128 include/yaz/marcdisp.h.
130 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
131 to UTF-8, UCS-32, wchar_t or Latin-1.
133 * Prototypes for yaz_iconv_-functions moved to separate header
134 include/yaz/yaz-iconv.h.
136 Make a few private functions 'static' in unix.c. This prevents
137 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
139 For ZOOM connection, the options targetImplementation{Id,Name,Version}
140 are set when Init Response is received.
142 New function ZOOM_connection_error_x similar to ZOOM_connection_error
143 but returns diagnostic set as well.
145 New function yaz_strerror which is a portable wrapper for
146 strerror/strerror_r/GetLastMessage.
148 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
149 is returned for MARC. If type is "oai", then OAI MARC is returned.
151 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
156 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
158 Fix bad race conditions on SIGTERM and terminate gracefully in
161 Move retrieval (data1) module to Zebra since nobody seems to be
164 Add GRS-1 render for ZOOM using same format as yaz-client.
168 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
170 Fix broken ESpec handling in data1 module.
172 SGML reader parses comments and makes them part of the data1 tree.
174 Added several type casts so that YAZ compiles as C++ code.
176 ZOOM didn't handle PDU encoding failures properly.
178 Added more Bib-1 diagnostics (approved extensions).
180 GNU configure: better check for iconv.
182 More portable use of accept, getpeername. Check for socklen_t. Use
183 int/size_t if socklen_t is not defined.
187 PQF parser rejects bad queries - including those with extra
188 characters in them. PQF parser used to silently ignore that.
189 Cleaner API for PQF added, which allows you to get detailed
190 error information for bad queries (see yaz/pquery.h).
192 Fixed bug in ZOOM_record_get for type "database".
194 Implemented mini iconv library supporting conversions between
195 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
197 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
201 Fixed ZOOM C record cache so that preferredRecordSyntax and
202 elementSetName is used to check for already fetched records.
206 Added three members in bend_initrequest structure to facilitate
207 character set negotiation.
209 Fixed a bug in frontend server that could cause indefinite
210 loops under rare conditions.
212 Revised character set utilities (charneg.h) so that encoding
213 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
215 For PQF, directive @term <type> sets term type for Scan/Search.
216 Here <type> is general, string, numeric, null. The term type
217 is inherited - just like @attr.
219 New call odr_set_charset that sets character set conversion for
220 international-strings on a ODR stream. Prototype is:
221 int odr_set_charset(ODR o, const char *to, const char *from);
222 The InternationalString is still represented as C string in YAZ
223 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
224 won't). On the protocol level, you can use any encoding.
226 Support for UNIX sockets in ZOOM.
228 Solaris recv sometimes returns errno == ENOENT. It is treated as
229 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
231 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
232 both client and server. Code by Morten Bøgeskov.
236 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
237 that they can be used directly from Visual Basic. You must recompile
238 your windows APP if you're using ZOOM.
240 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
241 Commands "lang" and "charset" sets language and character set respectively.
242 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
243 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
245 Attributes from multiple CCL fields may be OR'ed rather than merged
246 using directive "@field or". Fields are still merged by default -
247 equivalent to "@field merge".
249 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
252 Fixed bug in zget for parameter ExtendedServicesResponse.
258 Added PQF feature: '@attr type=value' may be written as '@type=value'.
260 Client displays USR.1:SearchResult-1 (hits per term).
262 Additional Search Info for search in Generic Frontend Server.
264 Fixed CCL parsing of "field=s".
266 WIN32 installer - using the excellent NSIS software from nullsoft.
268 Fixed CCL parsing of "field = - <number>".
270 Added function yaz_marc_decode that decodes MARC for line mode
271 display or XML (similar to that used by JZKit).
273 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
274 Z39.50. But ISO/ILL was, however.
276 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
277 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
279 http://lcweb.loc.gov/z3950/agency/amend/am2.html
280 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
284 New YAZ client features: Command completion and new commands:
285 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
286 Code provided by Jacob Poulsen.
288 New call oid_trav, that visits all registered OIDs via callback.
290 Function ZOOM_record_get now returns const char pointer rather than
291 void pointer. It saves a lot of type casts.
293 For YAZ client, command "auth" now allows you to set authentication
294 in IdPass style. It is enabled when three tokens are given - order
295 is user, group and password.
297 Fix memory leaks in MARC record handling for ZOOM.
299 New option for YAZ client, -k <kilobytes> that sets
300 maximum record size. Similar to -k option for generic frontend
301 server and yaz-ztest.
303 More fixes for scan. Non-zero stepSize handled. OID's fixes.
305 Prefix query parser reports "fail" when bad attribute set is given.
307 Fix in MARC decoder. Proximity logging. Fix for attribute set
308 in scan handler for server. Patches by Shigeru Ishida.
310 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
313 Configure option --with-openssl=<dir> now works when a directory is
314 specified. Patch provided by Morten Bøgeskov.
316 New option for YAZ client, -u <auth>, that sets authentication.
318 ZOOM fix: error information was sometimes "missing", since error
319 was cleared/reset too when it shouldn't.
321 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
325 Scan for ZOOM API. New object ZOOM_scanset. New functions
326 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
327 ZOOM_scanset_destroy.
329 New ZOOM function, ZOOM_connection_last_event, that returns type
330 of last event (such as "receive data", "send data", "apdu received",
333 New ZOOM option, schema, that specifies schema for retrieval.
335 New CCL feature. Qualifiers can be aliases for one or more
336 other qualifiers (if more than one is given, OR is used).
338 ZOOM uses named result sets if target supports it.
340 Two new YAZ client commands: . (dot, which sources a script of YAZ
341 client commands), and ! (to execute shell command.). Implemented
344 Working on Debian packages.
348 YAZ client enables named result sets only if target supports it.
350 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
352 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
353 with key="host" to get same result.
355 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
356 Function Z3950_resultset_record(s) returns references to records
357 "owned" by resultset. To become owner use Z3950_record_clone.
359 Function z_ext_record handles Extended Services. Thanks to
364 CCL Parser fix: ignore token comma when dealing with and-lists.
366 Documentation updates for COMSTACK.
368 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
369 Changed prototype Z3950_records. For some functions, int parameters
370 were changed to size_t.
372 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
375 New MARC decode/display function, marc_display_exl, which properly rejects
376 non-ISO2709 records. YAZ client uses it.
380 Fix bug: local attribute set wasn't set correctly in PQF strings.
384 * Old Z39.50 codecs no longer supported.
386 Added ZOOM C binding. See http://zoom.z3950.org/
388 Renamed states for COMSTACKs to avoid confusion with events.
390 Implemented cs_look and proper cs_rcvconnect.
392 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
394 Configure detects POSIX threads on OpenBSD.
396 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
397 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
399 When error is returned from present handler, non-surrogate diagnostic
400 is returned in present response (and fetch handler is no longer called).
402 * Minor adjustments to pquery parser (PQF). Token characters may be
403 escaped by using backslash (C-style).
405 PQF parser allows string attribute values to be specified. For @attr,
406 non-numeric characters after the equal-sign are treated as strings
407 (e.g. @attr 9=title).
409 CCL trunction character may be defined (@truncation in file)
411 * function zget_ExtendedServicesRequest sets waitAction to
412 waitIfPossible (was wait).
414 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
417 CCL operator names may be set in field definition files (CCL_bibset).
418 See ccl/bib1 for an example.
420 Fixes in ASN.1 compiler for C++ compatibility.
422 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
423 and "op_or" to avoid conflict with C++.
425 Fixed problem with GNU readline detection on Redhat 7.0.
427 Added step-size for Scan backend handler.
429 Fixed bug that made the frontend server crash when no attribute
430 set was specified for scan.
432 Front-end server automatically switches to original working directory
433 when installed as an NT service. Previously -w had to be specified to
436 Added extended attributes for retrieval module (data1), so that data1
437 records carry d1_readXML/SGML attributes. d1_read also supports
438 null-data rules ( <tag/>)
440 On UNIX when POSIX threads are available, a separate library libyazthread
441 is created. Programmers should link with that library and the yaz library
442 when using threads. The reason for the split was that some applications
443 on Linux, such as Apache, doesn't work well when using shared objects that
446 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
447 (or any frontend server) in SSL mode by specifying ssl: followed by
448 address. Only tested on UNIX.
450 Added feature for CCL module. Virtual structure s=al or s=ol generates
451 and-list and or-list respectively instead of phrase search.
455 * Added prefix "yaz_" for the functions log_init.., log_file.. and
456 log_mask_str. This was done to avoid name conflicts with other libraries
457 (such as other PHP extensions).
459 Added raw OID member for preferred record syntax (request_format_raw)
460 and returned record syntax (output_format_raw) for backend fetch method.
462 Config file yaz-config now accepts options so that it returns specific
463 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
465 Shared library support for UNIX using GNU libtool.
467 * Modified backend interface. Request/Response struct's replaced by
468 one read/write C struct. For example bend_fetchrequest and
469 bend_fetchresult have been replaced by single bend_fetch_rr struct.
470 Every handler - even search has to be registered in bend_init
471 handler. This means that the YAZ library no longer refers to
472 external functions and it makes it possible to make the whole
473 thing a single DLL/SO.
475 Added Segment handler for backend server.
477 Added Zmbol/Zebra administrative functions to YAZ client.
479 Threaded frontend server on UNIX (when POSIX Threads are available).
480 Starting the server with option -T enables multi-threading.
484 Added configure option --enable-comp/disable-comp to control use
485 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
486 located in sub directory asn.
488 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
489 in ${exec_prefix}/bin along with the other programs yaz-client and
492 GNU automake used to maintain makefiles.
496 Changed retrieval module so that we can load records with no abstract
497 syntax defined. Tagpaths in these records are fully composed of string
500 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
504 On UNIX, the generated makefile now supports a proper 'make install'.
505 The prefix can be set via GNU configure to set the install location
506 (default is /usr/local).
508 * YAZ programs client and ztest were renamed to yaz-client and
509 yaz-ztest to avoid conflicts when users install YAZ in "standard"
510 locations, such as /usr/bin,/usr/local/bin,etc.
512 * YAZ Header files were moved from include to include/yaz. YAZ Header
513 files are referred to as include <yaz/log.h> rather than <log.h>.
514 The YAZ include path (-I ..) is therefore the same as before. Programmers
515 should update their #include statements or use -Ipath/include/yaz
516 instead. The main motivation for doing this change is that YAZ header files
517 can be installed in "standard" locations /usr/include,/usr/local/include
518 without introducing conflicts, since ALL YAZ header files are stored
519 in subdirectory yaz (under /usr/include for example).
521 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
522 rather than project/workspace files. We switched because project files
523 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
526 Changed name of logging function, logf, to yaz_log, to prevent name
527 clash with some math-log functions. The YAZ header log.h defines logf
528 to yaz_log (#define) so there should be no incompatibilities by this
531 Added bend_start/bend_stop handlers for server. These handler are
532 called on start/stop of server. For windows they are called whenever
533 a service is started/stopped.
535 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
536 a fairly small ASN.1 compiler written in Tcl. The compiler is located
537 in util/yc.tcl. The auto-generated C code structures are, in a few
538 cases, incompatible with the old decoders. There are differences in the
539 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
540 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
541 The preprocessor variable ASN_COMPILED is defined when the compiled
542 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
543 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
544 wish to use the old encoders/decoders you can specify --disable-yc
547 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
548 version so that it supports both new - and old version of DB Update
550 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
551 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
552 change. The name parameter can be set to 0 in which no name is specified
553 for the construction. The macros odr_implicit and odr_explicit sets name
554 parameter to zero for the construction involved. New macros
555 odr_implicit_tag and odr_explicit_tag are similar to the others,
556 except that a name parameter is added. For programmers' that don't use
557 ODR they probably only need to change the call to z_APDU and z_External.
559 Added access control facility by interfacing the TCP wrapper library.
560 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
561 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
562 name of the daemon and enables the access control as specified in
563 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
565 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
566 den Dool <H.M.vdnDool@kub.nl>.
568 Added reference ID parameter to most functions in server API - refer
569 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
571 Changed name of ccl library to libccl.a (was ccl.a).
573 Fixed bug in decoder for Explain (Category TargetInfo).
575 Added support for GNU readline in client. Thanks to Jacob Poulsen
576 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
578 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
579 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
580 IMPLEMENTATION! This change was made to the development version before
581 the ZIG decided to retract the amendment. If any users MUST be
582 compatible with the original Update definition, PLEASE CONTACT US, and
583 we will include a separate definition corresponding to the old Update
584 ES. Note that because of the change to the ASN.1 of the
585 TaskPackageRecordStructure we cannot define a single structure that
586 will support both versions.
588 * Added const modifier to buffer parameter for some ODR/BER encoding
589 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
590 completeWAIS, odr_dumpBER.
592 Fixed bug in client.c which caused a crash when a scanResponse didn't
593 contain positionOfTerm.
595 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
596 * will cause an error in a client if a non-YAZ target sends both a
597 * list of Scan entries and non-surrogate diagnostics.
599 Retrieval module enhancements. Tag sets may be typed in the reference
600 to it. From the .abs-file the "tagset" directive takes a third optional
601 integer type for the tag set referenced. From a .tag-file the "include"
602 directive takes a third optional type as well. The old "type" directive
603 in the tag set itself is still recognized but acts as the default type
606 Backend interface change. Individual Scan terms returned from bend_scan
607 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
608 in include/backend.h.
610 Retrieval module enhancements. Multiple tag sets and attribute sets may
611 be specified in abstract syntax specs. Revised the error/warning for
612 logging messages reported by the retrieval module when reading the
615 Object Identifier system (oid_..) changed. The API is backwards
616 compatible but the oid-routines now allocates new OID's when needed.
617 Raw OID's may be specified in oid_getvalbyname.
619 YAZ now uses GNU configure to generate Makefile(s).
621 * Minor changes in some of the member names of DeleteResultSetRequest and
622 DeleteResultSetResponse. See include/proto.h.
624 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
625 and added member 'languages' in TargetInfo (which was missing).
627 Changed the way attribute sets are handled in the retrieval
628 module. These are now cached, just like the abstract syntaxes
631 Changed YAZ so that it links with compiled ASN.1.
633 Added Explain-schema definitions and mapping routines. The following
634 Explain categories have been implemented: AttributeDetails,
635 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
637 Fixed minor bug in Windows version of Server Library.
639 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
641 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
643 Added EXTERNAL: UNIverse Resource Report (non-standard).
645 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
646 ENUMERATED and SET OF.
648 * Added 'const' to some of the char pointer arguments for the
649 functions, data1_read_node, data1_getelementbytagname,
650 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
653 Fixed bug in data1_insert_taggeddata - the last_child member of
654 parent wasn't initialised.
656 * Changed data1_read_record and data1_read_node so that the supplied
657 "SGML"-buffer is read-only. In particular the resulting data1 - tree
658 doesn't refer to any parts of the "SGML"-buffer.
660 Fixed bug in server library (Windows version of statserv_remove).
662 * Changed code so that it compiles as C++. The type definition
663 of Odr_fun which is a member of Odr_arm was changed. The result is,
664 that an explicit typecast is needed for the fun pointer when
665 using Odr_arm - as in:
666 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
668 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
670 Implemented the new structured date and time definition as approved
671 by the ZIG. Added schemaId element to the specificTag in Espec-1
672 (also approved at the last ZIG). Thanks to RVDM.
674 Added some Object identifiers (RVDM).
676 Changed the Update Extended Service (RVDM).
678 Added command "refid" to client which specifies referenceId for
679 the following requests.
681 Implemented extended service handling for server. See ztest.c
682 for an example as well as backend.h. New handlers are registerd
685 * Changed interface for sort in server.
687 Added new members to statserv_options_block. It allows a server
688 to read options from another source than just the command line. Thanks
689 to Charles Woodfield.
691 * Changed definition of Z_Triple in file prt-grs.h - member boolean
692 renamed to zboolean. Some C++ compilers complained about the name.
694 Minor changes to gils.abs. Added index 's' (sort) on title
695 and date/time-last-modified.
699 Fixed bug in server library regarding inetd mode (-i). This bug
700 was introduced by release 1.4.
704 Added sort facility in client and backend server interface.
706 Fixed problem with dependencies in Makefile(s).
708 Fixed bugs for encoders/decoders of extended services and
711 Implemented sub-tree feature for schemas. Sub-trees are
712 referenced in *.abs-files. See explain.abs for an example
713 of the use of this feature.
715 Modified bib1.att; local attributes for ANY didn't include
716 ANY itself (only affects use of the retrieval module).
718 Fixed bug in plain SGML reader in function data1_read_node:
719 tags with prefix "var" was incorrectly interpreted as variants.
721 Added feature "sub-schemas" to enable references to - and definitions
722 of - group of elements.
724 * Removed member parent from type data1_element (in data1.h).
726 Implemented function odr_nullval() that returns the value of
729 * Removed member num_children from data1_node (in data1.h).
731 Made NT service interface part of the server library. The
732 function statserv_main uses the NT service when required and
733 calls the statserv_start / statserv_close routines.
735 Routine zget_SearchRequest and zget_PresentRequest fills
736 resultSetName/Id member with "default" instead of "Default".
738 Fixed memory leak in server. Request queue member wasn't freed.
740 Fixed nmem_exit so that memory is freed.
744 Revised the CCL parser utility to be thread safe.
746 Added function, oid_ent_to_oid, to replace the function
747 oid_getoidbyent, which is not thread safe.
749 * Added nmem_init and nmem_exit to initialize and release
750 NMEM resources. Function nmem_init should be called once in the
751 initial thread before NMEM/ODR is used. statserv.c and client.c
752 have been changed accordingly. The change was necessary to make
753 NMEM thread safe. The NMEM memory pool is shared amongst threads
754 in a process. Unix-based applications will still work fine without
757 Added NT Services interface for the the Z39.50 (statserv) Server.
758 Refer to the ztest.c source on the usage.
760 Windows 95/NT port using MSVC5.0. Project files are included in the
763 * Defined new 'global' handle for the retrieval (data1) system. The
764 new handled, data1_handle, describes the state of the data1 system.
765 This handle is passed as first argument to virtually all
766 data1 related routines. The functions data1_create and data1_destroy
767 creates and destroys a data1 handle respectively.
769 Added ODR encode stream member to all backend request structures
770 init, search, scan etc. This stream should be used to allocate all
771 memory used for the response when thread safe operation is needed.
773 Changed the comstack utility, cs_addstr, to be thread safe. The
774 returned hostname string returned by the function is now part the
777 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
778 function. The cs_straddr takes a COMSTACK handle as argument, so this
779 function must be used after cs_create and before bind/connect.
780 This function is thread safe.
782 Moved test server to 'ztest' directory - generic server code still
783 in 'server' directory.
785 Made prefix query (pquery.c) utility thread safe.
787 Added new function modifier YAZ_EXPORT to 'export' public DLL
788 functions when using windows (see include/yconfig.h).
790 Added definitions to the OID database (util/oid.c) (RVDM).
792 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
794 Added call to ccl_rpn_delete in client program.
796 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
797 release of RPN structure.
799 Added support for C++, headers uses extern "C" for public definitions.
800 With input from RVDM.
802 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
803 Thanks to Ronald van der Meer (RVDM).
805 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
807 Added support for private extensions to the OID database
808 (oid_setprivateoids()). Thanks to RVDM.
810 Added optional, physical ANY (key replication)
812 Fixed null-reference problem in GRS-1 output filter.
814 Proximity operator added to Prefix Query Format (PQF).
816 In test client command "base" accepts multiple databases.
818 Fixed bug in cs_close stack that caused trouble with WINSOCK.
822 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
824 Smallish bug-fixes in the new encoders/decoders (explain).
826 Bug fixed in DeleteRequest.
828 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
830 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
832 Added SOIF syntax (using private OID for now) to retrieval module and client.
834 Added Update extended service.
836 Added SearchResult-1 additional info structure.
838 Added optional CCL (ISO8777) interpreter as separate module. Available
841 --- 1.2 1996/6/10 (1st anniversary release)
843 Added Summary record syntax. Lightly tested.
845 Added OPAC record syntax. Untested.
847 Added ResourceReport service encoders/decoders. Untested.
849 Fixed bug in z_Unit - wrong tagging on unitSystem.
851 Fixed bug in the DiagRecs decoder.
853 Added options for max PDU size and session timeout to frontend-server.
855 Added documentation of query-language parsers and other supporting utilities.
857 [frontend-server] Added Attribute set to the bend_scanrequest API.
859 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
860 surrogate diagnostics were generated.
862 [retrieval] Allow multiple local values for attribute.
864 [retrieval] Allow multiple attributes per element in .abs files. index type.
866 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
870 Minor changes, mostly specific to Zebra's requirements (retrieval)
874 Repaired bug in frontend server when running multiple listening
875 endpoints in dynamic mode.
877 z_External() now won't break if a known, ASN.1 value comes encapsulated
878 in an octet-string. The value will pass through unmodified in an Odr_oct.
880 Added a bit of code to the demo client to decode & display
881 ASN.1-structured records represented in the octet-aligned branch of
882 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
884 Added z_ext_getentbyref() to the ASN module. Doc updated.
886 * Completed the SCAN definition in the ASN module. This may break SCAN
887 code based on older YAZ-versions at compile-time. The fix is easy -
890 * Added 'displayTerm' and OtherInformation to the TermInfo structure
891 under the SCAN definition. Remember to initialize this, server-people.
893 Comstack should now support the WAIS protocol in TCP/IP mode. Note
894 that this does not extend to ODR and ASN.
896 Comstack allows insertion of established socket (primarily for
897 inetd-operation of servers). Doc updated.
899 Front-end server can now start from the inetd in TCP mode. Doc
906 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
907 the rank and record number.
909 Adjustments to the frontend server.
911 Fixed diagnostic BER dumper. It ignored the file argument.
915 Various changes to retrieval module.
917 Changed the union discriminators of the protocol files from enums to
918 ints paired with #defines.
920 *Changed oident.class to oident.oclass to avoid a reserved word in C++
923 *Changed operator in the RPN structure to 'roperator', again to avoid a
926 Fixed problems in Explain decoders/encoders.
930 Memory bug in log module fixed.
934 Occasional malloc() of 0 bytes fixed in d1_espec.c.
936 Bug in Explain DatabaseInfo module fixed.
938 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
942 The shift to v1.0 signals that we now consider the *core* functionality
943 of YAZ reasonably stable (the core being more or less equivalent to
944 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
945 tested (Explain not at all - though that will happen soonish).
947 Minor changes to code to support Windows port.
949 Various minor changes after we're getting to use GRS-1 & co. more.
951 Added Espec-1 format.
953 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
954 of the protocol and it cannot be selected when encoding (maps into 'string'
955 when decoding). Needed to talk to some servers.
957 Demo client can request simple element set names.
959 Added Diagnostic Format encoders/decoders.
961 Added simple Close handling to frontend server (no hooks for resource
962 reporting yet), and demonstration client.
964 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
968 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
969 handled incorrectly when records were requested in the searchResponse. This
970 will only affect you if you use the frontend-server.
972 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
973 Test-client will ask for and print GRS1. Ztest will return dummy records
976 Added Explain encoders/decoders to the service-level API. Untested.
978 Added Extended Services: Item Order encoders and decoders to the Service-
979 level API. Untested. We could use a recent copy of the pertinent bits
980 of the ILL protocol to add those bits.
982 Added diagnostic format 1 encoders/decoders to the service-level API.
985 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
986 odr_cons.c, which causes a more correct output.
988 Fixed handling of searchRequest in frontend server. NextResultSetPosition
989 was always set to 0 when no records were requested in the searchRequest.
991 * Added better external-handling. This shouldn't harm old code that
992 *encodes* externals. It can break code that looks for a
993 'single-ASN1-type' representation, since those types that are known
994 are now decoded immediately. Look at the SUTRS sample code in
995 seshigh.c and client.c. Documentation updated.
997 Handling of structured records in bend_fetchresponse. Length -1 marks
998 structured record, type is deduced from format field.
1000 --- 1.0b2 1995/06/27
1001 Fairly quick maintenance release to add SUTRS support.
1003 Fixed handling of SUTRS records in the demonstration client.
1005 * Added format field to the bend_fetchrequest and bend_fetchresponce
1006 structures of the backend API (frontend server). When the record is
1007 returned, the value of the format field is mapped to an OID. The
1008 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1009 of the record. The special value VAL_NONE in the bend_request means
1010 that no specific format was requested by the client. Documentation
1011 updated accordingly. Test server (ztest) will return a fixed dummy
1012 SUTRS record if your client requests SUTRS.
1014 Documentation updated accordingly.
1016 You can now set external libraries and RANLIB support in the top-level
1020 First public release.
