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

132 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
136 New YAZ client features: Command completion and new commands:
137 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
138 Code provided by Jacob Poulsen.
140 New call oid_trav, that visits all registered OIDs via callback.
142 Function ZOOM_record_get now returns const char pointer rather than
143 void pointer. It saves a lot of type casts.
145 For YAZ client, command "auth" now allows you to set authentication
146 in IdPass style. It is enabled when three tokens are given - order
147 is user, group and password.
149 Fix memory leaks in MARC record handling for ZOOM.
151 New option for YAZ client, -k <kilobytes> that sets
152 maximum record size. Similar to -k option for generic frontend
153 server and yaz-ztest.
155 More fixes for scan. Non-zero stepSize handled. OID's fixes.
157 Prefix query parser reports "fail" when bad attribute set is given.
159 Fix in MARC decoder. Proximity logging. Fix for attribute set
160 in scan handler for server. Patches by Shigeru Ishida.
162 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
165 Configure option --with-openssl=<dir> now works when a directory is
166 specified. Patch provided by Morten Bøgeskov.
168 New option for YAZ client, -u <auth>, that sets authentication.
170 ZOOM fix: error information was sometimes "missing", since error
171 was cleared/reset too when it shouldn't.
173 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
177 Scan for ZOOM API. New object ZOOM_scanset. New functions
178 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
179 ZOOM_scanset_destroy.
181 New ZOOM function, ZOOM_connection_last_event, that returns type
182 of last event (such as "receive data", "send data", "apdu received",
185 New ZOOM option, schema, that specifies shema OID for retrieval.
187 New CCL feature. Qualifiers can be aliases for one or more
188 other qualifiers (if more than one is given, OR is used).
190 ZOOM uses named result sets if target supports it.
192 Two new YAZ client commands: . (dot, which sources a script of YAZ
193 client commands), and ! (to execute shell command.). Implemented
196 Working on Debian packages.
200 YAZ client enables named result sets only if target supports it.
202 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
204 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
205 with key="host" to get same result.
207 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
208 Function Z3950_resultset_record(s) returns references to records
209 "owned" by resultset. To become owner use Z3950_record_clone.
211 Function z_ext_record handles Extended Services. Thanks to
216 CCL Parser fix: ignore token comma when dealing with and-lists.
218 Documentation updates for COMSTACK.
220 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
221 Changed prototype Z3950_records. For some functions, int parameters
222 were changed to size_t.
224 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
227 New MARC decode/display function, marc_display_exl, which properly rejects
228 non-ISO2709 records. YAZ client uses it.
232 Fix bug: local attribute set wasn't set correctly in PQF strings.
236 * Old Z39.50 codecs no longer supported.
238 Added ZOOM C binding. See http://zoom.z3950.org/
240 Renamed states for COMSTACKs to avoid confusion with events.
242 Implemented cs_look and proper cs_rcvconnect.
244 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
246 Configure detects POSIX threads on OpenBSD.
248 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
249 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
251 When error is returned from present handler, non-surrogate diagnostic
252 is returned in present response (and fetch handler is no longer called).
254 * Minor adjustments to pquery parser (PQF). Token characters may be
255 escaped by using backslash (C-style).
257 PQF parser allows string attribute values to be specified. For @attr,
258 non-numeric characters after the equal-sign are treated as strings
259 (e.g. @attr 9=title).
261 CCL trunction character may be defined (@truncation in file)
263 * function zget_ExtendedServicesRequest sets waitAction to
264 waitIfPossible (was wait).
266 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
269 CCL operator names may be set in field definition files (CCL_bibset).
270 See ccl/bib1 for an example.
272 Fixes in ASN.1 compiler for C++ compatibility.
274 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
275 and "op_or" to avoid conflict with C++.
277 Fixed problem with GNU readline detection on Redhat 7.0.
279 Added step-size for Scan backend handler.
281 Fixed bug that made the frontend server crash when no attribute
282 set was specified for scan.
284 Front-end server automatically switches to original working directory
285 when installed as an NT service. Previously -w had to be specified to
288 Added extended attributes for retrieval module (data1), so that data1
289 records carry d1_readXML/SGML attributes. d1_read also supports
290 null-data rules ( <tag/>)
292 On UNIX when POSIX threads are available, a separate library libyazthread
293 is created. Programmers should link with that library and the yaz library
294 when using threads. The reason for the split was that some applications
295 on Linux, such as Apache, doesn't work well when using shared objects that
298 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
299 (or any frontend server) in SSL mode by specifying ssl: followed by
300 address. Only tested on UNIX.
302 Added feature for CCL module. Virtual structure s=al or s=ol generates
303 and-list and or-list respectively instead of phrase search.
307 * Added prefix "yaz_" for the functions log_init.., log_file.. and
308 log_mask_str. This was done to avoid name conflicts with other libraries
309 (such as other PHP extensions).
311 Added raw OID member for preferred record syntax (request_format_raw)
312 and returned record syntax (output_format_raw) for backend fetch method.
314 Config file yaz-config now accepts options so that it returns specific
315 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
317 Shared library support for UNIX using GNU libtool.
319 * Modified backend interface. Request/Response struct's replaced by
320 one read/write C struct. For example bend_fetchrequest and
321 bend_fetchresult have been replaced by single bend_fetch_rr struct.
322 Every handler - even search has to be registered in bend_init
323 handler. This means that the YAZ library no longer refers to
324 external functions and it makes it possible to make the whole
325 thing a single DLL/SO.
327 Added Segment handler for backend server.
329 Added Zmbol/Zebra administrative functions to YAZ client.
331 Threaded frontend server on UNIX (when POSIX Threads are available).
332 Starting the server with option -T enables multi-threading.
336 Added configure option --enable-comp/disable-comp to control use
337 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
338 located in sub directory asn.
340 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
341 in ${exec_prefix}/bin along with the other programs yaz-client and
344 GNU automake used to maintain makefiles.
348 Changed retrieval module so that we can load records with no abstract
349 syntax defined. Tagpaths in these records are fully composed of string
352 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
356 On UNIX, the generated makefile now supports a proper 'make install'.
357 The prefix can be set via GNU configure to set the install location
358 (default is /usr/local).
360 * YAZ programs client and ztest were renamed to yaz-client and
361 yaz-ztest to avoid conflicts when users install YAZ in "standard"
362 locations, such as /usr/bin,/usr/local/bin,etc.
364 * YAZ Header files were moved from include to include/yaz. YAZ Header
365 files are referred to as include <yaz/log.h> rather than <log.h>.
366 The YAZ include path (-I ..) is therefore the same as before. Programmers
367 should update their #include statements or use -Ipath/include/yaz
368 instead. The main motivation for doing this change is that YAZ header files
369 can be installed in "standard" locations /usr/include,/usr/local/include
370 without introducing conflicts, since ALL YAZ header files are stored
371 in subdirectory yaz (under /usr/include for example).
373 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
374 rather than project/workspace files. We switched because project files
375 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
378 Changed name of logging function, logf, to yaz_log, to prevent name
379 clash with some math-log functions. The YAZ header log.h defines logf
380 to yaz_log (#define) so there should be no incompatibilities by this
383 Added bend_start/bend_stop handlers for server. These handler are
384 called on start/stop of server. For windows they are called whenever
385 a service is started/stopped.
387 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
388 a fairly small ASN.1 compiler written in Tcl. The compiler is located
389 in util/yc.tcl. The auto-generated C code structures are, in a few
390 cases, incompatible with the old decoders. There are differences in the
391 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
392 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
393 The preprocessor variable ASN_COMPILED is defined when the compiled
394 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
395 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
396 wish to use the old encoders/decoders you can specify --disable-yc
399 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
400 version so that it supports both new - and old version of DB Update
402 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
403 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
404 change. The name parameter can be set to 0 in which no name is specified
405 for the construction. The macros odr_implicit and odr_explicit sets name
406 parameter to zero for the construction involved. New macros
407 odr_implicit_tag and odr_explicit_tag are similar to the others,
408 except that a name parameter is added. For programmers' that don't use
409 ODR they probably only need to change the call to z_APDU and z_External.
411 Added access control facility by interfacing the TCP wrapper library.
412 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
413 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
414 name of the daemon and enables the access control as specified in
415 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
417 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
418 den Dool <H.M.vdnDool@kub.nl>.
420 Added reference ID parameter to most functions in server API - refer
421 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
423 Changed name of ccl library to libccl.a (was ccl.a).
425 Fixed bug in decoder for Explain (Category TargetInfo).
427 Added support for GNU readline in client. Thanks to Jacob Poulsen
428 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
430 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
431 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
432 IMPLEMENTATION! This change was made to the development version before
433 the ZIG decided to retract the amendment. If any users MUST be
434 compatible with the original Update definition, PLEASE CONTACT US, and
435 we will include a separate definition corresponding to the old Update
436 ES. Note that because of the change to the ASN.1 of the
437 TaskPackageRecordStructure we cannot define a single structure that
438 will support both versions.
440 * Added const modifier to buffer parameter for some ODR/BER encoding
441 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
442 completeWAIS, odr_dumpBER.
444 Fixed bug in client.c which caused a crash when a scanResponse didn't
445 contain positionOfTerm.
447 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
448 * will cause an error in a client if a non-YAZ target sends both a
449 * list of Scan entries and non-surrogate diagnostics.
451 Retrieval module enhancements. Tag sets may be typed in the reference
452 to it. From the .abs-file the "tagset" directive takes a third optional
453 integer type for the tag set referenced. From a .tag-file the "include"
454 directive takes a third optional type as well. The old "type" directive
455 in the tag set itself is still recognized but acts as the default type
458 Backend interface change. Individual Scan terms returned from bend_scan
459 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
460 in include/backend.h.
462 Retrieval module enhancements. Multiple tag sets and attribute sets may
463 be specified in abstract syntax specs. Revised the error/warning for
464 logging messages reported by the retrieval module when reading the
467 Object Identifier system (oid_..) changed. The API is backwards
468 compatible but the oid-routines now allocates new OID's when needed.
469 Raw OID's may be specified in oid_getvalbyname.
471 YAZ now uses GNU configure to generate Makefile(s).
473 * Minor changes in some of the member names of DeleteResultSetRequest and
474 DeleteResultSetResponse. See include/proto.h.
476 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
477 and added member 'languages' in TargetInfo (which was missing).
479 Changed the way attribute sets are handled in the retrieval
480 module. These are now cached, just like the abstract syntaxes
483 Changed YAZ so that it links with compiled ASN.1.
485 Added Explain-schema definitions and mapping routines. The following
486 Explain categories have been implemented: AttributeDetails,
487 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
489 Fixed minor bug in Windows version of Server Library.
491 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
493 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
495 Added EXTERNAL: UNIverse Resource Report (non-standard).
497 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
498 ENUMERATED and SET OF.
500 * Added 'const' to some of the char pointer arguments for the
501 functions, data1_read_node, data1_getelementbytagname,
502 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
505 Fixed bug in data1_insert_taggeddata - the last_child member of
506 parent wasn't initialised.
508 * Changed data1_read_record and data1_read_node so that the supplied
509 "SGML"-buffer is read-only. In particular the resulting data1 - tree
510 doesn't refer to any parts of the "SGML"-buffer.
512 Fixed bug in server library (Windows version of statserv_remove).
514 * Changed code so that it compiles as C++. The type definition
515 of Odr_fun which is a member of Odr_arm was changed. The result is,
516 that an explicit typecast is needed for the fun pointer when
517 using Odr_arm - as in:
518 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
520 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
522 Implemented the new structured date and time definition as approved
523 by the ZIG. Added schemaId element to the specificTag in Espec-1
524 (also approved at the last ZIG). Thanks to RVDM.
526 Added some Object identifiers (RVDM).
528 Changed the Update Extended Service (RVDM).
530 Added command "refid" to client which specifies referenceId for
531 the following requests.
533 Implemented extended service handling for server. See ztest.c
534 for an example as well as backend.h. New handlers are registerd
537 * Changed interface for sort in server.
539 Added new members to statserv_options_block. It allows a server
540 to read options from another source than just the command line. Thanks
541 to Charles Woodfield.
543 * Changed definition of Z_Triple in file prt-grs.h - member boolean
544 renamed to zboolean. Some C++ compilers complained about the name.
546 Minor changes to gils.abs. Added index 's' (sort) on title
547 and date/time-last-modified.
551 Fixed bug in server library regarding inetd mode (-i). This bug
552 was introduced by release 1.4.
556 Added sort facility in client and backend server interface.
558 Fixed problem with dependencies in Makefile(s).
560 Fixed bugs for encoders/decoders of extended services and
563 Implemented sub-tree feature for schemas. Sub-trees are
564 referenced in *.abs-files. See explain.abs for an example
565 of the use of this feature.
567 Modified bib1.att; local attributes for ANY didn't include
568 ANY itself (only affects use of the retrieval module).
570 Fixed bug in plain SGML reader in function data1_read_node:
571 tags with prefix "var" was incorrectly interpreted as variants.
573 Added feature "sub-schemas" to enable references to - and definitions
574 of - group of elements.
576 * Removed member parent from type data1_element (in data1.h).
578 Implemented function odr_nullval() that returns the value of
581 * Removed member num_children from data1_node (in data1.h).
583 Made NT service interface part of the server library. The
584 function statserv_main uses the NT service when required and
585 calls the statserv_start / statserv_close routines.
587 Routine zget_SearchRequest and zget_PresentRequest fills
588 resultSetName/Id member with "default" instead of "Default".
590 Fixed memory leak in server. Request queue member wasn't freed.
592 Fixed nmem_exit so that memory is freed.
596 Revised the CCL parser utility to be thread safe.
598 Added function, oid_ent_to_oid, to replace the function
599 oid_getoidbyent, which is not thread safe.
601 * Added nmem_init and nmem_exit to initialize and release
602 NMEM resources. Function nmem_init should be called once in the
603 initial thread before NMEM/ODR is used. statserv.c and client.c
604 have been changed accordingly. The change was necessary to make
605 NMEM thread safe. The NMEM memory pool is shared amongst threads
606 in a process. Unix-based applications will still work fine without
609 Added NT Services interface for the the Z39.50 (statserv) Server.
610 Refer to the ztest.c source on the usage.
612 Windows 95/NT port using MSVC5.0. Project files are included in the
615 * Defined new 'global' handle for the retrieval (data1) system. The
616 new handled, data1_handle, describes the state of the data1 system.
617 This handle is passed as first argument to virtually all
618 data1 related routines. The functions data1_create and data1_destroy
619 creates and destroys a data1 handle respectively.
621 Added ODR encode stream member to all backend request structures
622 init, search, scan etc. This stream should be used to allocate all
623 memory used for the response when thread safe operation is needed.
625 Changed the comstack utility, cs_addstr, to be thread safe. The
626 returned hostname string returned by the function is now part the
629 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
630 function. The cs_straddr takes a COMSTACK handle as argument, so this
631 function must be used after cs_create and before bind/connect.
632 This function is thread safe.
634 Moved test server to 'ztest' directory - generic server code still
635 in 'server' directory.
637 Made prefix query (pquery.c) utility thread safe.
639 Added new function modifier YAZ_EXPORT to 'export' public DLL
640 functions when using windows (see include/yconfig.h).
642 Added definitions to the OID database (util/oid.c) (RVDM).
644 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
646 Added call to ccl_rpn_delete in client program.
648 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
649 release of RPN structure.
651 Added support for C++, headers uses extern "C" for public definitions.
652 With input from RVDM.
654 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
655 Thanks to Ronald van der Meer (RVDM).
657 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
659 Added support for private extensions to the OID database
660 (oid_setprivateoids()). Thanks to RVDM.
662 Added optional, physical ANY (key replication)
664 Fixed null-reference problem in GRS-1 output filter.
666 Proximity operator added to Prefix Query Format (PQF).
668 In test client command "base" accepts multiple databases.
670 Fixed bug in cs_close stack that caused trouble with WINSOCK.
674 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
676 Smallish bug-fixes in the new encoders/decoders (explain).
678 Bug fixed in DeleteRequest.
680 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
682 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
684 Added SOIF syntax (using private OID for now) to retrieval module and client.
686 Added Update extended service.
688 Added SearchResult-1 additional info structure.
690 Added optional CCL (ISO8777) interpreter as separate module. Available
693 --- 1.2 1996/6/10 (1st anniversary release)
695 Added Summary record syntax. Lightly tested.
697 Added OPAC record syntax. Untested.
699 Added ResourceReport service encoders/decoders. Untested.
701 Fixed bug in z_Unit - wrong tagging on unitSystem.
703 Fixed bug in the DiagRecs decoder.
705 Added options for max PDU size and session timeout to frontend-server.
707 Added documentation of query-language parsers and other supporting utilities.
709 [frontend-server] Added Attribute set to the bend_scanrequest API.
711 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
712 surrogate diagnostics were generated.
714 [retrieval] Allow multiple local values for attribute.
716 [retrieval] Allow multiple attributes per element in .abs files. index type.
718 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
722 Minor changes, mostly specific to Zebra's requirements (retrieval)
726 Repaired bug in frontend server when running multiple listening
727 endpoints in dynamic mode.
729 z_External() now won't break if a known, ASN.1 value comes encapsulated
730 in an octet-string. The value will pass through unmodified in an Odr_oct.
732 Added a bit of code to the demo client to decode & display
733 ASN.1-structured records represented in the octet-aligned branch of
734 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
736 Added z_ext_getentbyref() to the ASN module. Doc updated.
738 * Completed the SCAN definition in the ASN module. This may break SCAN
739 code based on older YAZ-versions at compile-time. The fix is easy -
742 * Added 'displayTerm' and OtherInformation to the TermInfo structure
743 under the SCAN definition. Remember to initialize this, server-people.
745 Comstack should now support the WAIS protocol in TCP/IP mode. Note
746 that this does not extend to ODR and ASN.
748 Comstack allows insertion of established socket (primarily for
749 inetd-operation of servers). Doc updated.
751 Front-end server can now start from the inetd in TCP mode. Doc
758 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
759 the rank and record number.
761 Adjustments to the frontend server.
763 Fixed diagnostic BER dumper. It ignored the file argument.
767 Various changes to retrieval module.
769 Changed the union discriminators of the protocol files from enums to
770 ints paired with #defines.
772 *Changed oident.class to oident.oclass to avoid a reserved word in C++
775 *Changed operator in the RPN structure to 'roperator', again to avoid a
778 Fixed problems in Explain decoders/encoders.
782 Memory bug in log module fixed.
786 Occasional malloc() of 0 bytes fixed in d1_espec.c.
788 Bug in Explain DatabaseInfo module fixed.
790 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
794 The shift to v1.0 signals that we now consider the *core* functionality
795 of YAZ reasonably stable (the core being more or less equivalent to
796 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
797 tested (Explain not at all - though that will happen soonish).
799 Minor changes to code to support Windows port.
801 Various minor changes after we're getting to use GRS-1 & co. more.
803 Added Espec-1 format.
805 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
806 of the protocol and it cannot be selected when encoding (maps into 'string'
807 when decoding). Needed to talk to some servers.
809 Demo client can request simple element set names.
811 Added Diagnostic Format encoders/decoders.
813 Added simple Close handling to frontend server (no hooks for resource
814 reporting yet), and demonstration client.
816 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
820 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
821 handled incorrectly when records were requested in the searchResponse. This
822 will only affect you if you use the frontend-server.
824 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
825 Test-client will ask for and print GRS1. Ztest will return dummy records
828 Added Explain encoders/decoders to the service-level API. Untested.
830 Added Extended Services: Item Order encoders and decoders to the Service-
831 level API. Untested. We could use a recent copy of the pertinent bits
832 of the ILL protocol to add those bits.
834 Added diagnostic format 1 encoders/decoders to the service-level API.
837 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
838 odr_cons.c, which causes a more correct output.
840 Fixed handling of searchRequest in frontend server. NextResultSetPosition
841 was always set to 0 when no records were requested in the searchRequest.
843 * Added better external-handling. This shouldn't harm old code that
844 *encodes* externals. It can break code that looks for a
845 'single-ASN1-type' representation, since those types that are known
846 are now decoded immediately. Look at the SUTRS sample code in
847 seshigh.c and client.c. Documentation updated.
849 Handling of structured records in bend_fetchresponse. Length -1 marks
850 structured record, type is deduced from format field.
853 Fairly quick maintenance release to add SUTRS support.
855 Fixed handling of SUTRS records in the demonstration client.
857 * Added format field to the bend_fetchrequest and bend_fetchresponce
858 structures of the backend API (frontend server). When the record is
859 returned, the value of the format field is mapped to an OID. The
860 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
861 of the record. The special value VAL_NONE in the bend_request means
862 that no specific format was requested by the client. Documentation
863 updated accordingly. Test server (ztest) will return a fixed dummy
864 SUTRS record if your client requests SUTRS.
866 Documentation updated accordingly.
868 You can now set external libraries and RANLIB support in the top-level
872 First public release.
