1 Possible compatibility problems with earlier versions marked with '*'.
5 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
7 Fix broken ESpec handling in data1 module.
9 SGML reader parses comments and makes them part of the data1 tree.
11 Added several type casts so that YAZ compiles as C++ code.
13 ZOOM didn't handle PDU encoding failures properly.
15 Added more Bib-1 diagnostics (approved extensions).
17 GNU configure: better check for iconv.
19 More portable use of accept, getpeername. Check for socklen_t. Use
20 int/size_t if socklen_t is not defined.
24 PQF parser rejects bad queries - including those with extra
25 characters in them. PQF parser used to silently ignore that.
26 Cleaner API for PQF added, which allows you to get detailed
27 error information for bad queries (see yaz/pquery.h).
29 Fixed bug in ZOOM_record_get for type "database".
31 Implemented mini iconv library supporting conversions between
32 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
34 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
38 Fixed ZOOM C record cache so that preferredRecordSyntax and
39 elementSetName is used to check for already fetched records.
43 Added three members in bend_initrequest structure to facilitate
44 character set negotiation.
46 Fixed a bug in frontend server that could cause indefinite
47 loops under rare conditions.
49 Revised character set utilities (charneg.h) so that encoding
50 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
52 For PQF, directive @term <type> sets term type for Scan/Search.
53 Here <type> is general, string, numeric, null. The term type
54 is inherited - just like @attr.
56 New call odr_set_charset that sets character set conversion for
57 international-strings on a ODR stream. Prototype is:
58 int odr_set_charset(ODR o, const char *to, const char *from);
59 The InternationalString is still represented as C string in YAZ
60 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
61 won't). On the protocol level, you can use any encoding.
63 Support for UNIX sockets in ZOOM.
65 Solaris recv sometimes returns errno == ENOENT. It is treated as
66 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
68 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
69 both client and server. Code by Morten Bøgeskov.
73 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
74 that they can be used directly from Visual Basic. You must recompile
75 your windows APP if you're using ZOOM.
77 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
78 Commands "lang" and "charset" sets language and character set respectively.
79 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
80 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
82 Attributes from multiple CCL fields may be OR'ed rather than merged
83 using directive "@field or". Fields are still merged by default -
84 equivalent to "@field merge".
86 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
89 Fixed bug in zget for parameter ExtendedServicesResponse.
95 Added PQF feature: '@attr type=value' may be written as '@type=value'.
97 Client displays USR.1:SearchResult-1 (hits per term).
99 Additional Search Info for search in Generic Frontend Server.
101 Fixed CCL parsing of "field=s".
103 WIN32 installer - using the excellent NSIS software from nullsoft.
105 Fixed CCL parsing of "field = - <number>".
107 Added function yaz_marc_decode that decodes MARC for line mode
108 display or XML (similar to that used by JZKit).
110 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
111 Z39.50. But ISO/ILL was, however.
113 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
114 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

117 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
121 New YAZ client features: Command completion and new commands:
122 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
123 Code provided by Jacob Poulsen.
125 New call oid_trav, that visits all registered OIDs via callback.
127 Function ZOOM_record_get now returns const char pointer rather than
128 void pointer. It saves a lot of type casts.
130 For YAZ client, command "auth" now allows you to set authentication
131 in IdPass style. It is enabled when three tokens are given - order
132 is user, group and password.
134 Fix memory leaks in MARC record handling for ZOOM.
136 New option for YAZ client, -k <kilobytes> that sets
137 maximum record size. Similar to -k option for generic frontend
138 server and yaz-ztest.
140 More fixes for scan. Non-zero stepSize handled. OID's fixes.
142 Prefix query parser reports "fail" when bad attribute set is given.
144 Fix in MARC decoder. Proximity logging. Fix for attribute set
145 in scan handler for server. Patches by Shigeru Ishida.
147 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
150 Configure option --with-openssl=<dir> now works when a directory is
151 specified. Patch provided by Morten Bøgeskov.
153 New option for YAZ client, -u <auth>, that sets authentication.
155 ZOOM fix: error information was sometimes "missing", since error
156 was cleared/reset too when it shouldn't.
158 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
162 Scan for ZOOM API. New object ZOOM_scanset. New functions
163 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
164 ZOOM_scanset_destroy.
166 New ZOOM function, ZOOM_connection_last_event, that returns type
167 of last event (such as "receive data", "send data", "apdu received",
170 New ZOOM option, schema, that specifies shema OID for retrieval.
172 New CCL feature. Qualifiers can be aliases for one or more
173 other qualifiers (if more than one is given, OR is used).
175 ZOOM uses named result sets if target supports it.
177 Two new YAZ client commands: . (dot, which sources a script of YAZ
178 client commands), and ! (to execute shell command.). Implemented
181 Working on Debian packages.
185 YAZ client enables named result sets only if target supports it.
187 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
189 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
190 with key="host" to get same result.
192 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
193 Function Z3950_resultset_record(s) returns references to records
194 "owned" by resultset. To become owner use Z3950_record_clone.
196 Function z_ext_record handles Extended Services. Thanks to
201 CCL Parser fix: ignore token comma when dealing with and-lists.
203 Documentation updates for COMSTACK.
205 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
206 Changed prototype Z3950_records. For some functions, int parameters
207 were changed to size_t.
209 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
212 New MARC decode/display function, marc_display_exl, which properly rejects
213 non-ISO2709 records. YAZ client uses it.
217 Fix bug: local attribute set wasn't set correctly in PQF strings.
221 * Old Z39.50 codecs no longer supported.
223 Added ZOOM C binding. See http://zoom.z3950.org/
225 Renamed states for COMSTACKs to avoid confusion with events.
227 Implemented cs_look and proper cs_rcvconnect.
229 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
231 Configure detects POSIX threads on OpenBSD.
233 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
234 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
236 When error is returned from present handler, non-surrogate diagnostic
237 is returned in present response (and fetch handler is no longer called).
239 * Minor adjustments to pquery parser (PQF). Token characters may be
240 escaped by using backslash (C-style).
242 PQF parser allows string attribute values to be specified. For @attr,
243 non-numeric characters after the equal-sign are treated as strings
244 (e.g. @attr 9=title).
246 CCL trunction character may be defined (@truncation in file)
248 * function zget_ExtendedServicesRequest sets waitAction to
249 waitIfPossible (was wait).
251 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
254 CCL operator names may be set in field definition files (CCL_bibset).
255 See ccl/bib1 for an example.
257 Fixes in ASN.1 compiler for C++ compatibility.
259 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
260 and "op_or" to avoid conflict with C++.
262 Fixed problem with GNU readline detection on Redhat 7.0.
264 Added step-size for Scan backend handler.
266 Fixed bug that made the frontend server crash when no attribute
267 set was specified for scan.
269 Front-end server automatically switches to original working directory
270 when installed as an NT service. Previously -w had to be specified to
273 Added extended attributes for retrieval module (data1), so that data1
274 records carry d1_readXML/SGML attributes. d1_read also supports
275 null-data rules ( <tag/>)
277 On UNIX when POSIX threads are available, a separate library libyazthread
278 is created. Programmers should link with that library and the yaz library
279 when using threads. The reason for the split was that some applications
280 on Linux, such as Apache, doesn't work well when using shared objects that
283 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
284 (or any frontend server) in SSL mode by specifying ssl: followed by
285 address. Only tested on UNIX.
287 Added feature for CCL module. Virtual structure s=al or s=ol generates
288 and-list and or-list respectively instead of phrase search.
292 * Added prefix "yaz_" for the functions log_init.., log_file.. and
293 log_mask_str. This was done to avoid name conflicts with other libraries
294 (such as other PHP extensions).
296 Added raw OID member for preferred record syntax (request_format_raw)
297 and returned record syntax (output_format_raw) for backend fetch method.
299 Config file yaz-config now accepts options so that it returns specific
300 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
302 Shared library support for UNIX using GNU libtool.
304 * Modified backend interface. Request/Response struct's replaced by
305 one read/write C struct. For example bend_fetchrequest and
306 bend_fetchresult have been replaced by single bend_fetch_rr struct.
307 Every handler - even search has to be registered in bend_init
308 handler. This means that the YAZ library no longer refers to
309 external functions and it makes it possible to make the whole
310 thing a single DLL/SO.
312 Added Segment handler for backend server.
314 Added Zmbol/Zebra administrative functions to YAZ client.
316 Threaded frontend server on UNIX (when POSIX Threads are available).
317 Starting the server with option -T enables multi-threading.
321 Added configure option --enable-comp/disable-comp to control use
322 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
323 located in sub directory asn.
325 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
326 in ${exec_prefix}/bin along with the other programs yaz-client and
329 GNU automake used to maintain makefiles.
333 Changed retrieval module so that we can load records with no abstract
334 syntax defined. Tagpaths in these records are fully composed of string
337 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
341 On UNIX, the generated makefile now supports a proper 'make install'.
342 The prefix can be set via GNU configure to set the install location
343 (default is /usr/local).
345 * YAZ programs client and ztest were renamed to yaz-client and
346 yaz-ztest to avoid conflicts when users install YAZ in "standard"
347 locations, such as /usr/bin,/usr/local/bin,etc.
349 * YAZ Header files were moved from include to include/yaz. YAZ Header
350 files are referred to as include <yaz/log.h> rather than <log.h>.
351 The YAZ include path (-I ..) is therefore the same as before. Programmers
352 should update their #include statements or use -Ipath/include/yaz
353 instead. The main motivation for doing this change is that YAZ header files
354 can be installed in "standard" locations /usr/include,/usr/local/include
355 without introducing conflicts, since ALL YAZ header files are stored
356 in subdirectory yaz (under /usr/include for example).
358 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
359 rather than project/workspace files. We switched because project files
360 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
363 Changed name of logging function, logf, to yaz_log, to prevent name
364 clash with some math-log functions. The YAZ header log.h defines logf
365 to yaz_log (#define) so there should be no incompatibilities by this
368 Added bend_start/bend_stop handlers for server. These handler are
369 called on start/stop of server. For windows they are called whenever
370 a service is started/stopped.
372 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
373 a fairly small ASN.1 compiler written in Tcl. The compiler is located
374 in util/yc.tcl. The auto-generated C code structures are, in a few
375 cases, incompatible with the old decoders. There are differences in the
376 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
377 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
378 The preprocessor variable ASN_COMPILED is defined when the compiled
379 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
380 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
381 wish to use the old encoders/decoders you can specify --disable-yc
384 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
385 version so that it supports both new - and old version of DB Update
387 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
388 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
389 change. The name parameter can be set to 0 in which no name is specified
390 for the construction. The macros odr_implicit and odr_explicit sets name
391 parameter to zero for the construction involved. New macros
392 odr_implicit_tag and odr_explicit_tag are similar to the others,
393 except that a name parameter is added. For programmers' that don't use
394 ODR they probably only need to change the call to z_APDU and z_External.
396 Added access control facility by interfacing the TCP wrapper library.
397 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
398 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
399 name of the daemon and enables the access control as specified in
400 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
402 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
403 den Dool <H.M.vdnDool@kub.nl>.
405 Added reference ID parameter to most functions in server API - refer
406 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
408 Changed name of ccl library to libccl.a (was ccl.a).
410 Fixed bug in decoder for Explain (Category TargetInfo).
412 Added support for GNU readline in client. Thanks to Jacob Poulsen
413 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
415 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
416 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
417 IMPLEMENTATION! This change was made to the development version before
418 the ZIG decided to retract the amendment. If any users MUST be
419 compatible with the original Update definition, PLEASE CONTACT US, and
420 we will include a separate definition corresponding to the old Update
421 ES. Note that because of the change to the ASN.1 of the
422 TaskPackageRecordStructure we cannot define a single structure that
423 will support both versions.
425 * Added const modifier to buffer parameter for some ODR/BER encoding
426 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
427 completeWAIS, odr_dumpBER.
429 Fixed bug in client.c which caused a crash when a scanResponse didn't
430 contain positionOfTerm.
432 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
433 * will cause an error in a client if a non-YAZ target sends both a
434 * list of Scan entries and non-surrogate diagnostics.
436 Retrieval module enhancements. Tag sets may be typed in the reference
437 to it. From the .abs-file the "tagset" directive takes a third optional
438 integer type for the tag set referenced. From a .tag-file the "include"
439 directive takes a third optional type as well. The old "type" directive
440 in the tag set itself is still recognized but acts as the default type
443 Backend interface change. Individual Scan terms returned from bend_scan
444 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
445 in include/backend.h.
447 Retrieval module enhancements. Multiple tag sets and attribute sets may
448 be specified in abstract syntax specs. Revised the error/warning for
449 logging messages reported by the retrieval module when reading the
452 Object Identifier system (oid_..) changed. The API is backwards
453 compatible but the oid-routines now allocates new OID's when needed.
454 Raw OID's may be specified in oid_getvalbyname.
456 YAZ now uses GNU configure to generate Makefile(s).
458 * Minor changes in some of the member names of DeleteResultSetRequest and
459 DeleteResultSetResponse. See include/proto.h.
461 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
462 and added member 'languages' in TargetInfo (which was missing).
464 Changed the way attribute sets are handled in the retrieval
465 module. These are now cached, just like the abstract syntaxes
468 Changed YAZ so that it links with compiled ASN.1.
470 Added Explain-schema definitions and mapping routines. The following
471 Explain categories have been implemented: AttributeDetails,
472 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
474 Fixed minor bug in Windows version of Server Library.
476 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
478 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
480 Added EXTERNAL: UNIverse Resource Report (non-standard).
482 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
483 ENUMERATED and SET OF.
485 * Added 'const' to some of the char pointer arguments for the
486 functions, data1_read_node, data1_getelementbytagname,
487 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
490 Fixed bug in data1_insert_taggeddata - the last_child member of
491 parent wasn't initialised.
493 * Changed data1_read_record and data1_read_node so that the supplied
494 "SGML"-buffer is read-only. In particular the resulting data1 - tree
495 doesn't refer to any parts of the "SGML"-buffer.
497 Fixed bug in server library (Windows version of statserv_remove).
499 * Changed code so that it compiles as C++. The type definition
500 of Odr_fun which is a member of Odr_arm was changed. The result is,
501 that an explicit typecast is needed for the fun pointer when
502 using Odr_arm - as in:
503 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
505 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
507 Implemented the new structured date and time definition as approved
508 by the ZIG. Added schemaId element to the specificTag in Espec-1
509 (also approved at the last ZIG). Thanks to RVDM.
511 Added some Object identifiers (RVDM).
513 Changed the Update Extended Service (RVDM).
515 Added command "refid" to client which specifies referenceId for
516 the following requests.
518 Implemented extended service handling for server. See ztest.c
519 for an example as well as backend.h. New handlers are registerd
522 * Changed interface for sort in server.
524 Added new members to statserv_options_block. It allows a server
525 to read options from another source than just the command line. Thanks
526 to Charles Woodfield.
528 * Changed definition of Z_Triple in file prt-grs.h - member boolean
529 renamed to zboolean. Some C++ compilers complained about the name.
531 Minor changes to gils.abs. Added index 's' (sort) on title
532 and date/time-last-modified.
536 Fixed bug in server library regarding inetd mode (-i). This bug
537 was introduced by release 1.4.
541 Added sort facility in client and backend server interface.
543 Fixed problem with dependencies in Makefile(s).
545 Fixed bugs for encoders/decoders of extended services and
548 Implemented sub-tree feature for schemas. Sub-trees are
549 referenced in *.abs-files. See explain.abs for an example
550 of the use of this feature.
552 Modified bib1.att; local attributes for ANY didn't include
553 ANY itself (only affects use of the retrieval module).
555 Fixed bug in plain SGML reader in function data1_read_node:
556 tags with prefix "var" was incorrectly interpreted as variants.
558 Added feature "sub-schemas" to enable references to - and definitions
559 of - group of elements.
561 * Removed member parent from type data1_element (in data1.h).
563 Implemented function odr_nullval() that returns the value of
566 * Removed member num_children from data1_node (in data1.h).
568 Made NT service interface part of the server library. The
569 function statserv_main uses the NT service when required and
570 calls the statserv_start / statserv_close routines.
572 Routine zget_SearchRequest and zget_PresentRequest fills
573 resultSetName/Id member with "default" instead of "Default".
575 Fixed memory leak in server. Request queue member wasn't freed.
577 Fixed nmem_exit so that memory is freed.
581 Revised the CCL parser utility to be thread safe.
583 Added function, oid_ent_to_oid, to replace the function
584 oid_getoidbyent, which is not thread safe.
586 * Added nmem_init and nmem_exit to initialize and release
587 NMEM resources. Function nmem_init should be called once in the
588 initial thread before NMEM/ODR is used. statserv.c and client.c
589 have been changed accordingly. The change was necessary to make
590 NMEM thread safe. The NMEM memory pool is shared amongst threads
591 in a process. Unix-based applications will still work fine without
594 Added NT Services interface for the the Z39.50 (statserv) Server.
595 Refer to the ztest.c source on the usage.
597 Windows 95/NT port using MSVC5.0. Project files are included in the
600 * Defined new 'global' handle for the retrieval (data1) system. The
601 new handled, data1_handle, describes the state of the data1 system.
602 This handle is passed as first argument to virtually all
603 data1 related routines. The functions data1_create and data1_destroy
604 creates and destroys a data1 handle respectively.
606 Added ODR encode stream member to all backend request structures
607 init, search, scan etc. This stream should be used to allocate all
608 memory used for the response when thread safe operation is needed.
610 Changed the comstack utility, cs_addstr, to be thread safe. The
611 returned hostname string returned by the function is now part the
614 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
615 function. The cs_straddr takes a COMSTACK handle as argument, so this
616 function must be used after cs_create and before bind/connect.
617 This function is thread safe.
619 Moved test server to 'ztest' directory - generic server code still
620 in 'server' directory.
622 Made prefix query (pquery.c) utility thread safe.
624 Added new function modifier YAZ_EXPORT to 'export' public DLL
625 functions when using windows (see include/yconfig.h).
627 Added definitions to the OID database (util/oid.c) (RVDM).
629 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
631 Added call to ccl_rpn_delete in client program.
633 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
634 release of RPN structure.
636 Added support for C++, headers uses extern "C" for public definitions.
637 With input from RVDM.
639 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
640 Thanks to Ronald van der Meer (RVDM).
642 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
644 Added support for private extensions to the OID database
645 (oid_setprivateoids()). Thanks to RVDM.
647 Added optional, physical ANY (key replication)
649 Fixed null-reference problem in GRS-1 output filter.
651 Proximity operator added to Prefix Query Format (PQF).
653 In test client command "base" accepts multiple databases.
655 Fixed bug in cs_close stack that caused trouble with WINSOCK.
659 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
661 Smallish bug-fixes in the new encoders/decoders (explain).
663 Bug fixed in DeleteRequest.
665 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
667 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
669 Added SOIF syntax (using private OID for now) to retrieval module and client.
671 Added Update extended service.
673 Added SearchResult-1 additional info structure.
675 Added optional CCL (ISO8777) interpreter as separate module. Available
678 --- 1.2 1996/6/10 (1st anniversary release)
680 Added Summary record syntax. Lightly tested.
682 Added OPAC record syntax. Untested.
684 Added ResourceReport service encoders/decoders. Untested.
686 Fixed bug in z_Unit - wrong tagging on unitSystem.
688 Fixed bug in the DiagRecs decoder.
690 Added options for max PDU size and session timeout to frontend-server.
692 Added documentation of query-language parsers and other supporting utilities.
694 [frontend-server] Added Attribute set to the bend_scanrequest API.
696 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
697 surrogate diagnostics were generated.
699 [retrieval] Allow multiple local values for attribute.
701 [retrieval] Allow multiple attributes per element in .abs files. index type.
703 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
707 Minor changes, mostly specific to Zebra's requirements (retrieval)
711 Repaired bug in frontend server when running multiple listening
712 endpoints in dynamic mode.
714 z_External() now won't break if a known, ASN.1 value comes encapsulated
715 in an octet-string. The value will pass through unmodified in an Odr_oct.
717 Added a bit of code to the demo client to decode & display
718 ASN.1-structured records represented in the octet-aligned branch of
719 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
721 Added z_ext_getentbyref() to the ASN module. Doc updated.
723 * Completed the SCAN definition in the ASN module. This may break SCAN
724 code based on older YAZ-versions at compile-time. The fix is easy -
727 * Added 'displayTerm' and OtherInformation to the TermInfo structure
728 under the SCAN definition. Remember to initialize this, server-people.
730 Comstack should now support the WAIS protocol in TCP/IP mode. Note
731 that this does not extend to ODR and ASN.
733 Comstack allows insertion of established socket (primarily for
734 inetd-operation of servers). Doc updated.
736 Front-end server can now start from the inetd in TCP mode. Doc
743 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
744 the rank and record number.
746 Adjustments to the frontend server.
748 Fixed diagnostic BER dumper. It ignored the file argument.
752 Various changes to retrieval module.
754 Changed the union discriminators of the protocol files from enums to
755 ints paired with #defines.
757 *Changed oident.class to oident.oclass to avoid a reserved word in C++
760 *Changed operator in the RPN structure to 'roperator', again to avoid a
763 Fixed problems in Explain decoders/encoders.
767 Memory bug in log module fixed.
771 Occasional malloc() of 0 bytes fixed in d1_espec.c.
773 Bug in Explain DatabaseInfo module fixed.
775 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
779 The shift to v1.0 signals that we now consider the *core* functionality
780 of YAZ reasonably stable (the core being more or less equivalent to
781 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
782 tested (Explain not at all - though that will happen soonish).
784 Minor changes to code to support Windows port.
786 Various minor changes after we're getting to use GRS-1 & co. more.
788 Added Espec-1 format.
790 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
791 of the protocol and it cannot be selected when encoding (maps into 'string'
792 when decoding). Needed to talk to some servers.
794 Demo client can request simple element set names.
796 Added Diagnostic Format encoders/decoders.
798 Added simple Close handling to frontend server (no hooks for resource
799 reporting yet), and demonstration client.
801 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
805 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
806 handled incorrectly when records were requested in the searchResponse. This
807 will only affect you if you use the frontend-server.
809 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
810 Test-client will ask for and print GRS1. Ztest will return dummy records
813 Added Explain encoders/decoders to the service-level API. Untested.
815 Added Extended Services: Item Order encoders and decoders to the Service-
816 level API. Untested. We could use a recent copy of the pertinent bits
817 of the ILL protocol to add those bits.
819 Added diagnostic format 1 encoders/decoders to the service-level API.
822 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
823 odr_cons.c, which causes a more correct output.
825 Fixed handling of searchRequest in frontend server. NextResultSetPosition
826 was always set to 0 when no records were requested in the searchRequest.
828 * Added better external-handling. This shouldn't harm old code that
829 *encodes* externals. It can break code that looks for a
830 'single-ASN1-type' representation, since those types that are known
831 are now decoded immediately. Look at the SUTRS sample code in
832 seshigh.c and client.c. Documentation updated.
834 Handling of structured records in bend_fetchresponse. Length -1 marks
835 structured record, type is deduced from format field.
838 Fairly quick maintenance release to add SUTRS support.
840 Fixed handling of SUTRS records in the demonstration client.
842 * Added format field to the bend_fetchrequest and bend_fetchresponce
843 structures of the backend API (frontend server). When the record is
844 returned, the value of the format field is mapped to an OID. The
845 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
846 of the record. The special value VAL_NONE in the bend_request means
847 that no specific format was requested by the client. Documentation
848 updated accordingly. Test server (ztest) will return a fixed dummy
849 SUTRS record if your client requests SUTRS.
851 Documentation updated accordingly.
853 You can now set external libraries and RANLIB support in the top-level
857 First public release.
