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

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