1 Possible compatibility problems with earlier versions marked with '*'.
3 Fix bad race conditions on SIGTERM and terminate gracefully in
6 Move retrieval (data1) module to Zebra since nobody seems to be
9 Add GRS-1 render for ZOOM using same format as yaz-client.
13 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
15 Fix broken ESpec handling in data1 module.
17 SGML reader parses comments and makes them part of the data1 tree.
19 Added several type casts so that YAZ compiles as C++ code.
21 ZOOM didn't handle PDU encoding failures properly.
23 Added more Bib-1 diagnostics (approved extensions).
25 GNU configure: better check for iconv.
27 More portable use of accept, getpeername. Check for socklen_t. Use
28 int/size_t if socklen_t is not defined.
32 PQF parser rejects bad queries - including those with extra
33 characters in them. PQF parser used to silently ignore that.
34 Cleaner API for PQF added, which allows you to get detailed
35 error information for bad queries (see yaz/pquery.h).
37 Fixed bug in ZOOM_record_get for type "database".
39 Implemented mini iconv library supporting conversions between
40 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
42 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
46 Fixed ZOOM C record cache so that preferredRecordSyntax and
47 elementSetName is used to check for already fetched records.
51 Added three members in bend_initrequest structure to facilitate
52 character set negotiation.
54 Fixed a bug in frontend server that could cause indefinite
55 loops under rare conditions.
57 Revised character set utilities (charneg.h) so that encoding
58 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
60 For PQF, directive @term <type> sets term type for Scan/Search.
61 Here <type> is general, string, numeric, null. The term type
62 is inherited - just like @attr.
64 New call odr_set_charset that sets character set conversion for
65 international-strings on a ODR stream. Prototype is:
66 int odr_set_charset(ODR o, const char *to, const char *from);
67 The InternationalString is still represented as C string in YAZ
68 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
69 won't). On the protocol level, you can use any encoding.
71 Support for UNIX sockets in ZOOM.
73 Solaris recv sometimes returns errno == ENOENT. It is treated as
74 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
76 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
77 both client and server. Code by Morten Bøgeskov.
81 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
82 that they can be used directly from Visual Basic. You must recompile
83 your windows APP if you're using ZOOM.
85 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
86 Commands "lang" and "charset" sets language and character set respectively.
87 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
88 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
90 Attributes from multiple CCL fields may be OR'ed rather than merged
91 using directive "@field or". Fields are still merged by default -
92 equivalent to "@field merge".
94 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
97 Fixed bug in zget for parameter ExtendedServicesResponse.
103 Added PQF feature: '@attr type=value' may be written as '@type=value'.
105 Client displays USR.1:SearchResult-1 (hits per term).
107 Additional Search Info for search in Generic Frontend Server.
109 Fixed CCL parsing of "field=s".
111 WIN32 installer - using the excellent NSIS software from nullsoft.
113 Fixed CCL parsing of "field = - <number>".
115 Added function yaz_marc_decode that decodes MARC for line mode
116 display or XML (similar to that used by JZKit).
118 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
119 Z39.50. But ISO/ILL was, however.
121 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
122 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

125 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
129 New YAZ client features: Command completion and new commands:
130 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
131 Code provided by Jacob Poulsen.
133 New call oid_trav, that visits all registered OIDs via callback.
135 Function ZOOM_record_get now returns const char pointer rather than
136 void pointer. It saves a lot of type casts.
138 For YAZ client, command "auth" now allows you to set authentication
139 in IdPass style. It is enabled when three tokens are given - order
140 is user, group and password.
142 Fix memory leaks in MARC record handling for ZOOM.
144 New option for YAZ client, -k <kilobytes> that sets
145 maximum record size. Similar to -k option for generic frontend
146 server and yaz-ztest.
148 More fixes for scan. Non-zero stepSize handled. OID's fixes.
150 Prefix query parser reports "fail" when bad attribute set is given.
152 Fix in MARC decoder. Proximity logging. Fix for attribute set
153 in scan handler for server. Patches by Shigeru Ishida.
155 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
158 Configure option --with-openssl=<dir> now works when a directory is
159 specified. Patch provided by Morten Bøgeskov.
161 New option for YAZ client, -u <auth>, that sets authentication.
163 ZOOM fix: error information was sometimes "missing", since error
164 was cleared/reset too when it shouldn't.
166 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
170 Scan for ZOOM API. New object ZOOM_scanset. New functions
171 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
172 ZOOM_scanset_destroy.
174 New ZOOM function, ZOOM_connection_last_event, that returns type
175 of last event (such as "receive data", "send data", "apdu received",
178 New ZOOM option, schema, that specifies shema OID for retrieval.
180 New CCL feature. Qualifiers can be aliases for one or more
181 other qualifiers (if more than one is given, OR is used).
183 ZOOM uses named result sets if target supports it.
185 Two new YAZ client commands: . (dot, which sources a script of YAZ
186 client commands), and ! (to execute shell command.). Implemented
189 Working on Debian packages.
193 YAZ client enables named result sets only if target supports it.
195 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
197 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
198 with key="host" to get same result.
200 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
201 Function Z3950_resultset_record(s) returns references to records
202 "owned" by resultset. To become owner use Z3950_record_clone.
204 Function z_ext_record handles Extended Services. Thanks to
209 CCL Parser fix: ignore token comma when dealing with and-lists.
211 Documentation updates for COMSTACK.
213 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
214 Changed prototype Z3950_records. For some functions, int parameters
215 were changed to size_t.
217 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
220 New MARC decode/display function, marc_display_exl, which properly rejects
221 non-ISO2709 records. YAZ client uses it.
225 Fix bug: local attribute set wasn't set correctly in PQF strings.
229 * Old Z39.50 codecs no longer supported.
231 Added ZOOM C binding. See http://zoom.z3950.org/
233 Renamed states for COMSTACKs to avoid confusion with events.
235 Implemented cs_look and proper cs_rcvconnect.
237 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
239 Configure detects POSIX threads on OpenBSD.
241 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
242 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
244 When error is returned from present handler, non-surrogate diagnostic
245 is returned in present response (and fetch handler is no longer called).
247 * Minor adjustments to pquery parser (PQF). Token characters may be
248 escaped by using backslash (C-style).
250 PQF parser allows string attribute values to be specified. For @attr,
251 non-numeric characters after the equal-sign are treated as strings
252 (e.g. @attr 9=title).
254 CCL trunction character may be defined (@truncation in file)
256 * function zget_ExtendedServicesRequest sets waitAction to
257 waitIfPossible (was wait).
259 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
262 CCL operator names may be set in field definition files (CCL_bibset).
263 See ccl/bib1 for an example.
265 Fixes in ASN.1 compiler for C++ compatibility.
267 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
268 and "op_or" to avoid conflict with C++.
270 Fixed problem with GNU readline detection on Redhat 7.0.
272 Added step-size for Scan backend handler.
274 Fixed bug that made the frontend server crash when no attribute
275 set was specified for scan.
277 Front-end server automatically switches to original working directory
278 when installed as an NT service. Previously -w had to be specified to
281 Added extended attributes for retrieval module (data1), so that data1
282 records carry d1_readXML/SGML attributes. d1_read also supports
283 null-data rules ( <tag/>)
285 On UNIX when POSIX threads are available, a separate library libyazthread
286 is created. Programmers should link with that library and the yaz library
287 when using threads. The reason for the split was that some applications
288 on Linux, such as Apache, doesn't work well when using shared objects that
291 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
292 (or any frontend server) in SSL mode by specifying ssl: followed by
293 address. Only tested on UNIX.
295 Added feature for CCL module. Virtual structure s=al or s=ol generates
296 and-list and or-list respectively instead of phrase search.
300 * Added prefix "yaz_" for the functions log_init.., log_file.. and
301 log_mask_str. This was done to avoid name conflicts with other libraries
302 (such as other PHP extensions).
304 Added raw OID member for preferred record syntax (request_format_raw)
305 and returned record syntax (output_format_raw) for backend fetch method.
307 Config file yaz-config now accepts options so that it returns specific
308 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
310 Shared library support for UNIX using GNU libtool.
312 * Modified backend interface. Request/Response struct's replaced by
313 one read/write C struct. For example bend_fetchrequest and
314 bend_fetchresult have been replaced by single bend_fetch_rr struct.
315 Every handler - even search has to be registered in bend_init
316 handler. This means that the YAZ library no longer refers to
317 external functions and it makes it possible to make the whole
318 thing a single DLL/SO.
320 Added Segment handler for backend server.
322 Added Zmbol/Zebra administrative functions to YAZ client.
324 Threaded frontend server on UNIX (when POSIX Threads are available).
325 Starting the server with option -T enables multi-threading.
329 Added configure option --enable-comp/disable-comp to control use
330 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
331 located in sub directory asn.
333 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
334 in ${exec_prefix}/bin along with the other programs yaz-client and
337 GNU automake used to maintain makefiles.
341 Changed retrieval module so that we can load records with no abstract
342 syntax defined. Tagpaths in these records are fully composed of string
345 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
349 On UNIX, the generated makefile now supports a proper 'make install'.
350 The prefix can be set via GNU configure to set the install location
351 (default is /usr/local).
353 * YAZ programs client and ztest were renamed to yaz-client and
354 yaz-ztest to avoid conflicts when users install YAZ in "standard"
355 locations, such as /usr/bin,/usr/local/bin,etc.
357 * YAZ Header files were moved from include to include/yaz. YAZ Header
358 files are referred to as include <yaz/log.h> rather than <log.h>.
359 The YAZ include path (-I ..) is therefore the same as before. Programmers
360 should update their #include statements or use -Ipath/include/yaz
361 instead. The main motivation for doing this change is that YAZ header files
362 can be installed in "standard" locations /usr/include,/usr/local/include
363 without introducing conflicts, since ALL YAZ header files are stored
364 in subdirectory yaz (under /usr/include for example).
366 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
367 rather than project/workspace files. We switched because project files
368 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
371 Changed name of logging function, logf, to yaz_log, to prevent name
372 clash with some math-log functions. The YAZ header log.h defines logf
373 to yaz_log (#define) so there should be no incompatibilities by this
376 Added bend_start/bend_stop handlers for server. These handler are
377 called on start/stop of server. For windows they are called whenever
378 a service is started/stopped.
380 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
381 a fairly small ASN.1 compiler written in Tcl. The compiler is located
382 in util/yc.tcl. The auto-generated C code structures are, in a few
383 cases, incompatible with the old decoders. There are differences in the
384 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
385 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
386 The preprocessor variable ASN_COMPILED is defined when the compiled
387 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
388 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
389 wish to use the old encoders/decoders you can specify --disable-yc
392 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
393 version so that it supports both new - and old version of DB Update
395 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
396 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
397 change. The name parameter can be set to 0 in which no name is specified
398 for the construction. The macros odr_implicit and odr_explicit sets name
399 parameter to zero for the construction involved. New macros
400 odr_implicit_tag and odr_explicit_tag are similar to the others,
401 except that a name parameter is added. For programmers' that don't use
402 ODR they probably only need to change the call to z_APDU and z_External.
404 Added access control facility by interfacing the TCP wrapper library.
405 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
406 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
407 name of the daemon and enables the access control as specified in
408 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
410 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
411 den Dool <H.M.vdnDool@kub.nl>.
413 Added reference ID parameter to most functions in server API - refer
414 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
416 Changed name of ccl library to libccl.a (was ccl.a).
418 Fixed bug in decoder for Explain (Category TargetInfo).
420 Added support for GNU readline in client. Thanks to Jacob Poulsen
421 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
423 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
424 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
425 IMPLEMENTATION! This change was made to the development version before
426 the ZIG decided to retract the amendment. If any users MUST be
427 compatible with the original Update definition, PLEASE CONTACT US, and
428 we will include a separate definition corresponding to the old Update
429 ES. Note that because of the change to the ASN.1 of the
430 TaskPackageRecordStructure we cannot define a single structure that
431 will support both versions.
433 * Added const modifier to buffer parameter for some ODR/BER encoding
434 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
435 completeWAIS, odr_dumpBER.
437 Fixed bug in client.c which caused a crash when a scanResponse didn't
438 contain positionOfTerm.
440 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
441 * will cause an error in a client if a non-YAZ target sends both a
442 * list of Scan entries and non-surrogate diagnostics.
444 Retrieval module enhancements. Tag sets may be typed in the reference
445 to it. From the .abs-file the "tagset" directive takes a third optional
446 integer type for the tag set referenced. From a .tag-file the "include"
447 directive takes a third optional type as well. The old "type" directive
448 in the tag set itself is still recognized but acts as the default type
451 Backend interface change. Individual Scan terms returned from bend_scan
452 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
453 in include/backend.h.
455 Retrieval module enhancements. Multiple tag sets and attribute sets may
456 be specified in abstract syntax specs. Revised the error/warning for
457 logging messages reported by the retrieval module when reading the
460 Object Identifier system (oid_..) changed. The API is backwards
461 compatible but the oid-routines now allocates new OID's when needed.
462 Raw OID's may be specified in oid_getvalbyname.
464 YAZ now uses GNU configure to generate Makefile(s).
466 * Minor changes in some of the member names of DeleteResultSetRequest and
467 DeleteResultSetResponse. See include/proto.h.
469 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
470 and added member 'languages' in TargetInfo (which was missing).
472 Changed the way attribute sets are handled in the retrieval
473 module. These are now cached, just like the abstract syntaxes
476 Changed YAZ so that it links with compiled ASN.1.
478 Added Explain-schema definitions and mapping routines. The following
479 Explain categories have been implemented: AttributeDetails,
480 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
482 Fixed minor bug in Windows version of Server Library.
484 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
486 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
488 Added EXTERNAL: UNIverse Resource Report (non-standard).
490 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
491 ENUMERATED and SET OF.
493 * Added 'const' to some of the char pointer arguments for the
494 functions, data1_read_node, data1_getelementbytagname,
495 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
498 Fixed bug in data1_insert_taggeddata - the last_child member of
499 parent wasn't initialised.
501 * Changed data1_read_record and data1_read_node so that the supplied
502 "SGML"-buffer is read-only. In particular the resulting data1 - tree
503 doesn't refer to any parts of the "SGML"-buffer.
505 Fixed bug in server library (Windows version of statserv_remove).
507 * Changed code so that it compiles as C++. The type definition
508 of Odr_fun which is a member of Odr_arm was changed. The result is,
509 that an explicit typecast is needed for the fun pointer when
510 using Odr_arm - as in:
511 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
513 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
515 Implemented the new structured date and time definition as approved
516 by the ZIG. Added schemaId element to the specificTag in Espec-1
517 (also approved at the last ZIG). Thanks to RVDM.
519 Added some Object identifiers (RVDM).
521 Changed the Update Extended Service (RVDM).
523 Added command "refid" to client which specifies referenceId for
524 the following requests.
526 Implemented extended service handling for server. See ztest.c
527 for an example as well as backend.h. New handlers are registerd
530 * Changed interface for sort in server.
532 Added new members to statserv_options_block. It allows a server
533 to read options from another source than just the command line. Thanks
534 to Charles Woodfield.
536 * Changed definition of Z_Triple in file prt-grs.h - member boolean
537 renamed to zboolean. Some C++ compilers complained about the name.
539 Minor changes to gils.abs. Added index 's' (sort) on title
540 and date/time-last-modified.
544 Fixed bug in server library regarding inetd mode (-i). This bug
545 was introduced by release 1.4.
549 Added sort facility in client and backend server interface.
551 Fixed problem with dependencies in Makefile(s).
553 Fixed bugs for encoders/decoders of extended services and
556 Implemented sub-tree feature for schemas. Sub-trees are
557 referenced in *.abs-files. See explain.abs for an example
558 of the use of this feature.
560 Modified bib1.att; local attributes for ANY didn't include
561 ANY itself (only affects use of the retrieval module).
563 Fixed bug in plain SGML reader in function data1_read_node:
564 tags with prefix "var" was incorrectly interpreted as variants.
566 Added feature "sub-schemas" to enable references to - and definitions
567 of - group of elements.
569 * Removed member parent from type data1_element (in data1.h).
571 Implemented function odr_nullval() that returns the value of
574 * Removed member num_children from data1_node (in data1.h).
576 Made NT service interface part of the server library. The
577 function statserv_main uses the NT service when required and
578 calls the statserv_start / statserv_close routines.
580 Routine zget_SearchRequest and zget_PresentRequest fills
581 resultSetName/Id member with "default" instead of "Default".
583 Fixed memory leak in server. Request queue member wasn't freed.
585 Fixed nmem_exit so that memory is freed.
589 Revised the CCL parser utility to be thread safe.
591 Added function, oid_ent_to_oid, to replace the function
592 oid_getoidbyent, which is not thread safe.
594 * Added nmem_init and nmem_exit to initialize and release
595 NMEM resources. Function nmem_init should be called once in the
596 initial thread before NMEM/ODR is used. statserv.c and client.c
597 have been changed accordingly. The change was necessary to make
598 NMEM thread safe. The NMEM memory pool is shared amongst threads
599 in a process. Unix-based applications will still work fine without
602 Added NT Services interface for the the Z39.50 (statserv) Server.
603 Refer to the ztest.c source on the usage.
605 Windows 95/NT port using MSVC5.0. Project files are included in the
608 * Defined new 'global' handle for the retrieval (data1) system. The
609 new handled, data1_handle, describes the state of the data1 system.
610 This handle is passed as first argument to virtually all
611 data1 related routines. The functions data1_create and data1_destroy
612 creates and destroys a data1 handle respectively.
614 Added ODR encode stream member to all backend request structures
615 init, search, scan etc. This stream should be used to allocate all
616 memory used for the response when thread safe operation is needed.
618 Changed the comstack utility, cs_addstr, to be thread safe. The
619 returned hostname string returned by the function is now part the
622 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
623 function. The cs_straddr takes a COMSTACK handle as argument, so this
624 function must be used after cs_create and before bind/connect.
625 This function is thread safe.
627 Moved test server to 'ztest' directory - generic server code still
628 in 'server' directory.
630 Made prefix query (pquery.c) utility thread safe.
632 Added new function modifier YAZ_EXPORT to 'export' public DLL
633 functions when using windows (see include/yconfig.h).
635 Added definitions to the OID database (util/oid.c) (RVDM).
637 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
639 Added call to ccl_rpn_delete in client program.
641 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
642 release of RPN structure.
644 Added support for C++, headers uses extern "C" for public definitions.
645 With input from RVDM.
647 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
648 Thanks to Ronald van der Meer (RVDM).
650 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
652 Added support for private extensions to the OID database
653 (oid_setprivateoids()). Thanks to RVDM.
655 Added optional, physical ANY (key replication)
657 Fixed null-reference problem in GRS-1 output filter.
659 Proximity operator added to Prefix Query Format (PQF).
661 In test client command "base" accepts multiple databases.
663 Fixed bug in cs_close stack that caused trouble with WINSOCK.
667 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
669 Smallish bug-fixes in the new encoders/decoders (explain).
671 Bug fixed in DeleteRequest.
673 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
675 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
677 Added SOIF syntax (using private OID for now) to retrieval module and client.
679 Added Update extended service.
681 Added SearchResult-1 additional info structure.
683 Added optional CCL (ISO8777) interpreter as separate module. Available
686 --- 1.2 1996/6/10 (1st anniversary release)
688 Added Summary record syntax. Lightly tested.
690 Added OPAC record syntax. Untested.
692 Added ResourceReport service encoders/decoders. Untested.
694 Fixed bug in z_Unit - wrong tagging on unitSystem.
696 Fixed bug in the DiagRecs decoder.
698 Added options for max PDU size and session timeout to frontend-server.
700 Added documentation of query-language parsers and other supporting utilities.
702 [frontend-server] Added Attribute set to the bend_scanrequest API.
704 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
705 surrogate diagnostics were generated.
707 [retrieval] Allow multiple local values for attribute.
709 [retrieval] Allow multiple attributes per element in .abs files. index type.
711 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
715 Minor changes, mostly specific to Zebra's requirements (retrieval)
719 Repaired bug in frontend server when running multiple listening
720 endpoints in dynamic mode.
722 z_External() now won't break if a known, ASN.1 value comes encapsulated
723 in an octet-string. The value will pass through unmodified in an Odr_oct.
725 Added a bit of code to the demo client to decode & display
726 ASN.1-structured records represented in the octet-aligned branch of
727 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
729 Added z_ext_getentbyref() to the ASN module. Doc updated.
731 * Completed the SCAN definition in the ASN module. This may break SCAN
732 code based on older YAZ-versions at compile-time. The fix is easy -
735 * Added 'displayTerm' and OtherInformation to the TermInfo structure
736 under the SCAN definition. Remember to initialize this, server-people.
738 Comstack should now support the WAIS protocol in TCP/IP mode. Note
739 that this does not extend to ODR and ASN.
741 Comstack allows insertion of established socket (primarily for
742 inetd-operation of servers). Doc updated.
744 Front-end server can now start from the inetd in TCP mode. Doc
751 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
752 the rank and record number.
754 Adjustments to the frontend server.
756 Fixed diagnostic BER dumper. It ignored the file argument.
760 Various changes to retrieval module.
762 Changed the union discriminators of the protocol files from enums to
763 ints paired with #defines.
765 *Changed oident.class to oident.oclass to avoid a reserved word in C++
768 *Changed operator in the RPN structure to 'roperator', again to avoid a
771 Fixed problems in Explain decoders/encoders.
775 Memory bug in log module fixed.
779 Occasional malloc() of 0 bytes fixed in d1_espec.c.
781 Bug in Explain DatabaseInfo module fixed.
783 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
787 The shift to v1.0 signals that we now consider the *core* functionality
788 of YAZ reasonably stable (the core being more or less equivalent to
789 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
790 tested (Explain not at all - though that will happen soonish).
792 Minor changes to code to support Windows port.
794 Various minor changes after we're getting to use GRS-1 & co. more.
796 Added Espec-1 format.
798 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
799 of the protocol and it cannot be selected when encoding (maps into 'string'
800 when decoding). Needed to talk to some servers.
802 Demo client can request simple element set names.
804 Added Diagnostic Format encoders/decoders.
806 Added simple Close handling to frontend server (no hooks for resource
807 reporting yet), and demonstration client.
809 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
813 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
814 handled incorrectly when records were requested in the searchResponse. This
815 will only affect you if you use the frontend-server.
817 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
818 Test-client will ask for and print GRS1. Ztest will return dummy records
821 Added Explain encoders/decoders to the service-level API. Untested.
823 Added Extended Services: Item Order encoders and decoders to the Service-
824 level API. Untested. We could use a recent copy of the pertinent bits
825 of the ILL protocol to add those bits.
827 Added diagnostic format 1 encoders/decoders to the service-level API.
830 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
831 odr_cons.c, which causes a more correct output.
833 Fixed handling of searchRequest in frontend server. NextResultSetPosition
834 was always set to 0 when no records were requested in the searchRequest.
836 * Added better external-handling. This shouldn't harm old code that
837 *encodes* externals. It can break code that looks for a
838 'single-ASN1-type' representation, since those types that are known
839 are now decoded immediately. Look at the SUTRS sample code in
840 seshigh.c and client.c. Documentation updated.
842 Handling of structured records in bend_fetchresponse. Length -1 marks
843 structured record, type is deduced from format field.
846 Fairly quick maintenance release to add SUTRS support.
848 Fixed handling of SUTRS records in the demonstration client.
850 * Added format field to the bend_fetchrequest and bend_fetchresponce
851 structures of the backend API (frontend server). When the record is
852 returned, the value of the format field is mapped to an OID. The
853 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
854 of the record. The special value VAL_NONE in the bend_request means
855 that no specific format was requested by the client. Documentation
856 updated accordingly. Test server (ztest) will return a fixed dummy
857 SUTRS record if your client requests SUTRS.
859 Documentation updated accordingly.
861 You can now set external libraries and RANLIB support in the top-level
865 First public release.
