1 Possible compatibility problems with earlier versions marked with '*'.
3 ZOOM_record_get supports type "xml" in which case OAI MARC is
4 returned for MARC. If type is "MarcXML" , MARC XML is returned.
6 yaz_marc_decode supports MARC XML as well. The xml parameter
7 specifies type. See include/marcdisp.h
9 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
14 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
16 Fix bad race conditions on SIGTERM and terminate gracefully in
19 Move retrieval (data1) module to Zebra since nobody seems to be
22 Add GRS-1 render for ZOOM using same format as yaz-client.
26 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
28 Fix broken ESpec handling in data1 module.
30 SGML reader parses comments and makes them part of the data1 tree.
32 Added several type casts so that YAZ compiles as C++ code.
34 ZOOM didn't handle PDU encoding failures properly.
36 Added more Bib-1 diagnostics (approved extensions).
38 GNU configure: better check for iconv.
40 More portable use of accept, getpeername. Check for socklen_t. Use
41 int/size_t if socklen_t is not defined.
45 PQF parser rejects bad queries - including those with extra
46 characters in them. PQF parser used to silently ignore that.
47 Cleaner API for PQF added, which allows you to get detailed
48 error information for bad queries (see yaz/pquery.h).
50 Fixed bug in ZOOM_record_get for type "database".
52 Implemented mini iconv library supporting conversions between
53 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
55 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
59 Fixed ZOOM C record cache so that preferredRecordSyntax and
60 elementSetName is used to check for already fetched records.
64 Added three members in bend_initrequest structure to facilitate
65 character set negotiation.
67 Fixed a bug in frontend server that could cause indefinite
68 loops under rare conditions.
70 Revised character set utilities (charneg.h) so that encoding
71 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
73 For PQF, directive @term <type> sets term type for Scan/Search.
74 Here <type> is general, string, numeric, null. The term type
75 is inherited - just like @attr.
77 New call odr_set_charset that sets character set conversion for
78 international-strings on a ODR stream. Prototype is:
79 int odr_set_charset(ODR o, const char *to, const char *from);
80 The InternationalString is still represented as C string in YAZ
81 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
82 won't). On the protocol level, you can use any encoding.
84 Support for UNIX sockets in ZOOM.
86 Solaris recv sometimes returns errno == ENOENT. It is treated as
87 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
89 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
90 both client and server. Code by Morten Bøgeskov.
94 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
95 that they can be used directly from Visual Basic. You must recompile
96 your windows APP if you're using ZOOM.
98 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
99 Commands "lang" and "charset" sets language and character set respectively.
100 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
101 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
103 Attributes from multiple CCL fields may be OR'ed rather than merged
104 using directive "@field or". Fields are still merged by default -
105 equivalent to "@field merge".
107 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
110 Fixed bug in zget for parameter ExtendedServicesResponse.
116 Added PQF feature: '@attr type=value' may be written as '@type=value'.
118 Client displays USR.1:SearchResult-1 (hits per term).
120 Additional Search Info for search in Generic Frontend Server.
122 Fixed CCL parsing of "field=s".
124 WIN32 installer - using the excellent NSIS software from nullsoft.
126 Fixed CCL parsing of "field = - <number>".
128 Added function yaz_marc_decode that decodes MARC for line mode
129 display or XML (similar to that used by JZKit).
131 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
132 Z39.50. But ISO/ILL was, however.
134 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
135 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

142 New YAZ client features: Command completion and new commands:
143 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
144 Code provided by Jacob Poulsen.
146 New call oid_trav, that visits all registered OIDs via callback.
148 Function ZOOM_record_get now returns const char pointer rather than
149 void pointer. It saves a lot of type casts.
151 For YAZ client, command "auth" now allows you to set authentication
152 in IdPass style. It is enabled when three tokens are given - order
153 is user, group and password.
155 Fix memory leaks in MARC record handling for ZOOM.
157 New option for YAZ client, -k <kilobytes> that sets
158 maximum record size. Similar to -k option for generic frontend
159 server and yaz-ztest.
161 More fixes for scan. Non-zero stepSize handled. OID's fixes.
163 Prefix query parser reports "fail" when bad attribute set is given.
165 Fix in MARC decoder. Proximity logging. Fix for attribute set
166 in scan handler for server. Patches by Shigeru Ishida.
168 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
171 Configure option --with-openssl=<dir> now works when a directory is
172 specified. Patch provided by Morten Bøgeskov.
174 New option for YAZ client, -u <auth>, that sets authentication.
176 ZOOM fix: error information was sometimes "missing", since error
177 was cleared/reset too when it shouldn't.
179 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
183 Scan for ZOOM API. New object ZOOM_scanset. New functions
184 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
185 ZOOM_scanset_destroy.
187 New ZOOM function, ZOOM_connection_last_event, that returns type
188 of last event (such as "receive data", "send data", "apdu received",
191 New ZOOM option, schema, that specifies shema OID for retrieval.
193 New CCL feature. Qualifiers can be aliases for one or more
194 other qualifiers (if more than one is given, OR is used).
196 ZOOM uses named result sets if target supports it.
198 Two new YAZ client commands: . (dot, which sources a script of YAZ
199 client commands), and ! (to execute shell command.). Implemented
202 Working on Debian packages.
206 YAZ client enables named result sets only if target supports it.
208 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
210 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
211 with key="host" to get same result.
213 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
214 Function Z3950_resultset_record(s) returns references to records
215 "owned" by resultset. To become owner use Z3950_record_clone.
217 Function z_ext_record handles Extended Services. Thanks to
222 CCL Parser fix: ignore token comma when dealing with and-lists.
224 Documentation updates for COMSTACK.
226 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
227 Changed prototype Z3950_records. For some functions, int parameters
228 were changed to size_t.
230 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
233 New MARC decode/display function, marc_display_exl, which properly rejects
234 non-ISO2709 records. YAZ client uses it.
238 Fix bug: local attribute set wasn't set correctly in PQF strings.
242 * Old Z39.50 codecs no longer supported.
244 Added ZOOM C binding. See http://zoom.z3950.org/
246 Renamed states for COMSTACKs to avoid confusion with events.
248 Implemented cs_look and proper cs_rcvconnect.
250 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
252 Configure detects POSIX threads on OpenBSD.
254 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
255 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
257 When error is returned from present handler, non-surrogate diagnostic
258 is returned in present response (and fetch handler is no longer called).
260 * Minor adjustments to pquery parser (PQF). Token characters may be
261 escaped by using backslash (C-style).
263 PQF parser allows string attribute values to be specified. For @attr,
264 non-numeric characters after the equal-sign are treated as strings
265 (e.g. @attr 9=title).
267 CCL trunction character may be defined (@truncation in file)
269 * function zget_ExtendedServicesRequest sets waitAction to
270 waitIfPossible (was wait).
272 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
275 CCL operator names may be set in field definition files (CCL_bibset).
276 See ccl/bib1 for an example.
278 Fixes in ASN.1 compiler for C++ compatibility.
280 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
281 and "op_or" to avoid conflict with C++.
283 Fixed problem with GNU readline detection on Redhat 7.0.
285 Added step-size for Scan backend handler.
287 Fixed bug that made the frontend server crash when no attribute
288 set was specified for scan.
290 Front-end server automatically switches to original working directory
291 when installed as an NT service. Previously -w had to be specified to
294 Added extended attributes for retrieval module (data1), so that data1
295 records carry d1_readXML/SGML attributes. d1_read also supports
296 null-data rules ( <tag/>)
298 On UNIX when POSIX threads are available, a separate library libyazthread
299 is created. Programmers should link with that library and the yaz library
300 when using threads. The reason for the split was that some applications
301 on Linux, such as Apache, doesn't work well when using shared objects that
304 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
305 (or any frontend server) in SSL mode by specifying ssl: followed by
306 address. Only tested on UNIX.
308 Added feature for CCL module. Virtual structure s=al or s=ol generates
309 and-list and or-list respectively instead of phrase search.
313 * Added prefix "yaz_" for the functions log_init.., log_file.. and
314 log_mask_str. This was done to avoid name conflicts with other libraries
315 (such as other PHP extensions).
317 Added raw OID member for preferred record syntax (request_format_raw)
318 and returned record syntax (output_format_raw) for backend fetch method.
320 Config file yaz-config now accepts options so that it returns specific
321 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
323 Shared library support for UNIX using GNU libtool.
325 * Modified backend interface. Request/Response struct's replaced by
326 one read/write C struct. For example bend_fetchrequest and
327 bend_fetchresult have been replaced by single bend_fetch_rr struct.
328 Every handler - even search has to be registered in bend_init
329 handler. This means that the YAZ library no longer refers to
330 external functions and it makes it possible to make the whole
331 thing a single DLL/SO.
333 Added Segment handler for backend server.
335 Added Zmbol/Zebra administrative functions to YAZ client.
337 Threaded frontend server on UNIX (when POSIX Threads are available).
338 Starting the server with option -T enables multi-threading.
342 Added configure option --enable-comp/disable-comp to control use
343 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
344 located in sub directory asn.
346 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
347 in ${exec_prefix}/bin along with the other programs yaz-client and
350 GNU automake used to maintain makefiles.
354 Changed retrieval module so that we can load records with no abstract
355 syntax defined. Tagpaths in these records are fully composed of string
358 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
362 On UNIX, the generated makefile now supports a proper 'make install'.
363 The prefix can be set via GNU configure to set the install location
364 (default is /usr/local).
366 * YAZ programs client and ztest were renamed to yaz-client and
367 yaz-ztest to avoid conflicts when users install YAZ in "standard"
368 locations, such as /usr/bin,/usr/local/bin,etc.
370 * YAZ Header files were moved from include to include/yaz. YAZ Header
371 files are referred to as include <yaz/log.h> rather than <log.h>.
372 The YAZ include path (-I ..) is therefore the same as before. Programmers
373 should update their #include statements or use -Ipath/include/yaz
374 instead. The main motivation for doing this change is that YAZ header files
375 can be installed in "standard" locations /usr/include,/usr/local/include
376 without introducing conflicts, since ALL YAZ header files are stored
377 in subdirectory yaz (under /usr/include for example).
379 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
380 rather than project/workspace files. We switched because project files
381 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
384 Changed name of logging function, logf, to yaz_log, to prevent name
385 clash with some math-log functions. The YAZ header log.h defines logf
386 to yaz_log (#define) so there should be no incompatibilities by this
389 Added bend_start/bend_stop handlers for server. These handler are
390 called on start/stop of server. For windows they are called whenever
391 a service is started/stopped.
393 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
394 a fairly small ASN.1 compiler written in Tcl. The compiler is located
395 in util/yc.tcl. The auto-generated C code structures are, in a few
396 cases, incompatible with the old decoders. There are differences in the
397 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
398 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
399 The preprocessor variable ASN_COMPILED is defined when the compiled
400 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
401 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
402 wish to use the old encoders/decoders you can specify --disable-yc
405 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
406 version so that it supports both new - and old version of DB Update
408 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
409 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
410 change. The name parameter can be set to 0 in which no name is specified
411 for the construction. The macros odr_implicit and odr_explicit sets name
412 parameter to zero for the construction involved. New macros
413 odr_implicit_tag and odr_explicit_tag are similar to the others,
414 except that a name parameter is added. For programmers' that don't use
415 ODR they probably only need to change the call to z_APDU and z_External.
417 Added access control facility by interfacing the TCP wrapper library.
418 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
419 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
420 name of the daemon and enables the access control as specified in
421 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
423 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
424 den Dool <H.M.vdnDool@kub.nl>.
426 Added reference ID parameter to most functions in server API - refer
427 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
429 Changed name of ccl library to libccl.a (was ccl.a).
431 Fixed bug in decoder for Explain (Category TargetInfo).
433 Added support for GNU readline in client. Thanks to Jacob Poulsen
434 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
436 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
437 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
438 IMPLEMENTATION! This change was made to the development version before
439 the ZIG decided to retract the amendment. If any users MUST be
440 compatible with the original Update definition, PLEASE CONTACT US, and
441 we will include a separate definition corresponding to the old Update
442 ES. Note that because of the change to the ASN.1 of the
443 TaskPackageRecordStructure we cannot define a single structure that
444 will support both versions.
446 * Added const modifier to buffer parameter for some ODR/BER encoding
447 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
448 completeWAIS, odr_dumpBER.
450 Fixed bug in client.c which caused a crash when a scanResponse didn't
451 contain positionOfTerm.
453 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
454 * will cause an error in a client if a non-YAZ target sends both a
455 * list of Scan entries and non-surrogate diagnostics.
457 Retrieval module enhancements. Tag sets may be typed in the reference
458 to it. From the .abs-file the "tagset" directive takes a third optional
459 integer type for the tag set referenced. From a .tag-file the "include"
460 directive takes a third optional type as well. The old "type" directive
461 in the tag set itself is still recognized but acts as the default type
464 Backend interface change. Individual Scan terms returned from bend_scan
465 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
466 in include/backend.h.
468 Retrieval module enhancements. Multiple tag sets and attribute sets may
469 be specified in abstract syntax specs. Revised the error/warning for
470 logging messages reported by the retrieval module when reading the
473 Object Identifier system (oid_..) changed. The API is backwards
474 compatible but the oid-routines now allocates new OID's when needed.
475 Raw OID's may be specified in oid_getvalbyname.
477 YAZ now uses GNU configure to generate Makefile(s).
479 * Minor changes in some of the member names of DeleteResultSetRequest and
480 DeleteResultSetResponse. See include/proto.h.
482 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
483 and added member 'languages' in TargetInfo (which was missing).
485 Changed the way attribute sets are handled in the retrieval
486 module. These are now cached, just like the abstract syntaxes
489 Changed YAZ so that it links with compiled ASN.1.
491 Added Explain-schema definitions and mapping routines. The following
492 Explain categories have been implemented: AttributeDetails,
493 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
495 Fixed minor bug in Windows version of Server Library.
497 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
499 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
501 Added EXTERNAL: UNIverse Resource Report (non-standard).
503 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
504 ENUMERATED and SET OF.
506 * Added 'const' to some of the char pointer arguments for the
507 functions, data1_read_node, data1_getelementbytagname,
508 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
511 Fixed bug in data1_insert_taggeddata - the last_child member of
512 parent wasn't initialised.
514 * Changed data1_read_record and data1_read_node so that the supplied
515 "SGML"-buffer is read-only. In particular the resulting data1 - tree
516 doesn't refer to any parts of the "SGML"-buffer.
518 Fixed bug in server library (Windows version of statserv_remove).
520 * Changed code so that it compiles as C++. The type definition
521 of Odr_fun which is a member of Odr_arm was changed. The result is,
522 that an explicit typecast is needed for the fun pointer when
523 using Odr_arm - as in:
524 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
526 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
528 Implemented the new structured date and time definition as approved
529 by the ZIG. Added schemaId element to the specificTag in Espec-1
530 (also approved at the last ZIG). Thanks to RVDM.
532 Added some Object identifiers (RVDM).
534 Changed the Update Extended Service (RVDM).
536 Added command "refid" to client which specifies referenceId for
537 the following requests.
539 Implemented extended service handling for server. See ztest.c
540 for an example as well as backend.h. New handlers are registerd
543 * Changed interface for sort in server.
545 Added new members to statserv_options_block. It allows a server
546 to read options from another source than just the command line. Thanks
547 to Charles Woodfield.
549 * Changed definition of Z_Triple in file prt-grs.h - member boolean
550 renamed to zboolean. Some C++ compilers complained about the name.
552 Minor changes to gils.abs. Added index 's' (sort) on title
553 and date/time-last-modified.
557 Fixed bug in server library regarding inetd mode (-i). This bug
558 was introduced by release 1.4.
562 Added sort facility in client and backend server interface.
564 Fixed problem with dependencies in Makefile(s).
566 Fixed bugs for encoders/decoders of extended services and
569 Implemented sub-tree feature for schemas. Sub-trees are
570 referenced in *.abs-files. See explain.abs for an example
571 of the use of this feature.
573 Modified bib1.att; local attributes for ANY didn't include
574 ANY itself (only affects use of the retrieval module).
576 Fixed bug in plain SGML reader in function data1_read_node:
577 tags with prefix "var" was incorrectly interpreted as variants.
579 Added feature "sub-schemas" to enable references to - and definitions
580 of - group of elements.
582 * Removed member parent from type data1_element (in data1.h).
584 Implemented function odr_nullval() that returns the value of
587 * Removed member num_children from data1_node (in data1.h).
589 Made NT service interface part of the server library. The
590 function statserv_main uses the NT service when required and
591 calls the statserv_start / statserv_close routines.
593 Routine zget_SearchRequest and zget_PresentRequest fills
594 resultSetName/Id member with "default" instead of "Default".
596 Fixed memory leak in server. Request queue member wasn't freed.
598 Fixed nmem_exit so that memory is freed.
602 Revised the CCL parser utility to be thread safe.
604 Added function, oid_ent_to_oid, to replace the function
605 oid_getoidbyent, which is not thread safe.
607 * Added nmem_init and nmem_exit to initialize and release
608 NMEM resources. Function nmem_init should be called once in the
609 initial thread before NMEM/ODR is used. statserv.c and client.c
610 have been changed accordingly. The change was necessary to make
611 NMEM thread safe. The NMEM memory pool is shared amongst threads
612 in a process. Unix-based applications will still work fine without
615 Added NT Services interface for the the Z39.50 (statserv) Server.
616 Refer to the ztest.c source on the usage.
618 Windows 95/NT port using MSVC5.0. Project files are included in the
621 * Defined new 'global' handle for the retrieval (data1) system. The
622 new handled, data1_handle, describes the state of the data1 system.
623 This handle is passed as first argument to virtually all
624 data1 related routines. The functions data1_create and data1_destroy
625 creates and destroys a data1 handle respectively.
627 Added ODR encode stream member to all backend request structures
628 init, search, scan etc. This stream should be used to allocate all
629 memory used for the response when thread safe operation is needed.
631 Changed the comstack utility, cs_addstr, to be thread safe. The
632 returned hostname string returned by the function is now part the
635 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
636 function. The cs_straddr takes a COMSTACK handle as argument, so this
637 function must be used after cs_create and before bind/connect.
638 This function is thread safe.
640 Moved test server to 'ztest' directory - generic server code still
641 in 'server' directory.
643 Made prefix query (pquery.c) utility thread safe.
645 Added new function modifier YAZ_EXPORT to 'export' public DLL
646 functions when using windows (see include/yconfig.h).
648 Added definitions to the OID database (util/oid.c) (RVDM).
650 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
652 Added call to ccl_rpn_delete in client program.
654 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
655 release of RPN structure.
657 Added support for C++, headers uses extern "C" for public definitions.
658 With input from RVDM.
660 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
661 Thanks to Ronald van der Meer (RVDM).
663 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
665 Added support for private extensions to the OID database
666 (oid_setprivateoids()). Thanks to RVDM.
668 Added optional, physical ANY (key replication)
670 Fixed null-reference problem in GRS-1 output filter.
672 Proximity operator added to Prefix Query Format (PQF).
674 In test client command "base" accepts multiple databases.
676 Fixed bug in cs_close stack that caused trouble with WINSOCK.
680 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
682 Smallish bug-fixes in the new encoders/decoders (explain).
684 Bug fixed in DeleteRequest.
686 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
688 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.

692 Added Update extended service.
694 Added SearchResult-1 additional info structure.
696 Added optional CCL (ISO8777) interpreter as separate module. Available
699 --- 1.2 1996/6/10 (1st anniversary release)
701 Added Summary record syntax. Lightly tested.
703 Added OPAC record syntax. Untested.
705 Added ResourceReport service encoders/decoders. Untested.
707 Fixed bug in z_Unit - wrong tagging on unitSystem.
709 Fixed bug in the DiagRecs decoder.
711 Added options for max PDU size and session timeout to frontend-server.
713 Added documentation of query-language parsers and other supporting utilities.
715 [frontend-server] Added Attribute set to the bend_scanrequest API.
717 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
718 surrogate diagnostics were generated.
720 [retrieval] Allow multiple local values for attribute.
722 [retrieval] Allow multiple attributes per element in .abs files. index type.
724 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
728 Minor changes, mostly specific to Zebra's requirements (retrieval)
732 Repaired bug in frontend server when running multiple listening
733 endpoints in dynamic mode.
735 z_External() now won't break if a known, ASN.1 value comes encapsulated
736 in an octet-string. The value will pass through unmodified in an Odr_oct.
738 Added a bit of code to the demo client to decode & display
739 ASN.1-structured records represented in the octet-aligned branch of
740 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
742 Added z_ext_getentbyref() to the ASN module. Doc updated.
744 * Completed the SCAN definition in the ASN module. This may break SCAN
745 code based on older YAZ-versions at compile-time. The fix is easy -
748 * Added 'displayTerm' and OtherInformation to the TermInfo structure
749 under the SCAN definition. Remember to initialize this, server-people.
751 Comstack should now support the WAIS protocol in TCP/IP mode. Note
752 that this does not extend to ODR and ASN.
754 Comstack allows insertion of established socket (primarily for
755 inetd-operation of servers). Doc updated.
757 Front-end server can now start from the inetd in TCP mode. Doc
764 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
765 the rank and record number.
767 Adjustments to the frontend server.
769 Fixed diagnostic BER dumper. It ignored the file argument.
773 Various changes to retrieval module.
775 Changed the union discriminators of the protocol files from enums to
776 ints paired with #defines.
778 *Changed oident.class to oident.oclass to avoid a reserved word in C++
781 *Changed operator in the RPN structure to 'roperator', again to avoid a
784 Fixed problems in Explain decoders/encoders.
788 Memory bug in log module fixed.
792 Occasional malloc() of 0 bytes fixed in d1_espec.c.
794 Bug in Explain DatabaseInfo module fixed.
796 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
800 The shift to v1.0 signals that we now consider the *core* functionality
801 of YAZ reasonably stable (the core being more or less equivalent to
802 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
803 tested (Explain not at all - though that will happen soonish).
805 Minor changes to code to support Windows port.
807 Various minor changes after we're getting to use GRS-1 & co. more.
809 Added Espec-1 format.
811 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
812 of the protocol and it cannot be selected when encoding (maps into 'string'
813 when decoding). Needed to talk to some servers.
815 Demo client can request simple element set names.
817 Added Diagnostic Format encoders/decoders.
819 Added simple Close handling to frontend server (no hooks for resource
820 reporting yet), and demonstration client.
822 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
826 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
827 handled incorrectly when records were requested in the searchResponse. This
828 will only affect you if you use the frontend-server.
830 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
831 Test-client will ask for and print GRS1. Ztest will return dummy records
834 Added Explain encoders/decoders to the service-level API. Untested.
836 Added Extended Services: Item Order encoders and decoders to the Service-
837 level API. Untested. We could use a recent copy of the pertinent bits
838 of the ILL protocol to add those bits.
840 Added diagnostic format 1 encoders/decoders to the service-level API.
843 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
844 odr_cons.c, which causes a more correct output.
846 Fixed handling of searchRequest in frontend server. NextResultSetPosition
847 was always set to 0 when no records were requested in the searchRequest.
849 * Added better external-handling. This shouldn't harm old code that
850 *encodes* externals. It can break code that looks for a
851 'single-ASN1-type' representation, since those types that are known
852 are now decoded immediately. Look at the SUTRS sample code in
853 seshigh.c and client.c. Documentation updated.
855 Handling of structured records in bend_fetchresponse. Length -1 marks
856 structured record, type is deduced from format field.
859 Fairly quick maintenance release to add SUTRS support.
861 Fixed handling of SUTRS records in the demonstration client.
863 * Added format field to the bend_fetchrequest and bend_fetchresponce
864 structures of the backend API (frontend server). When the record is
865 returned, the value of the format field is mapped to an OID. The
866 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
867 of the record. The special value VAL_NONE in the bend_request means
868 that no specific format was requested by the client. Documentation
869 updated accordingly. Test server (ztest) will return a fixed dummy
870 SUTRS record if your client requests SUTRS.
872 Documentation updated accordingly.
874 You can now set external libraries and RANLIB support in the top-level
878 First public release.
