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

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