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

141 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
145 New YAZ client features: Command completion and new commands:
146 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
147 Code provided by Jacob Poulsen.
149 New call oid_trav, that visits all registered OIDs via callback.
151 Function ZOOM_record_get now returns const char pointer rather than
152 void pointer. It saves a lot of type casts.
154 For YAZ client, command "auth" now allows you to set authentication
155 in IdPass style. It is enabled when three tokens are given - order
156 is user, group and password.
158 Fix memory leaks in MARC record handling for ZOOM.
160 New option for YAZ client, -k <kilobytes> that sets
161 maximum record size. Similar to -k option for generic frontend
162 server and yaz-ztest.
164 More fixes for scan. Non-zero stepSize handled. OID's fixes.
166 Prefix query parser reports "fail" when bad attribute set is given.
168 Fix in MARC decoder. Proximity logging. Fix for attribute set
169 in scan handler for server. Patches by Shigeru Ishida.
171 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
174 Configure option --with-openssl=<dir> now works when a directory is
175 specified. Patch provided by Morten Bøgeskov.
177 New option for YAZ client, -u <auth>, that sets authentication.
179 ZOOM fix: error information was sometimes "missing", since error
180 was cleared/reset too when it shouldn't.
182 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
186 Scan for ZOOM API. New object ZOOM_scanset. New functions
187 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
188 ZOOM_scanset_destroy.
190 New ZOOM function, ZOOM_connection_last_event, that returns type
191 of last event (such as "receive data", "send data", "apdu received",
194 New ZOOM option, schema, that specifies shema OID for retrieval.
196 New CCL feature. Qualifiers can be aliases for one or more
197 other qualifiers (if more than one is given, OR is used).
199 ZOOM uses named result sets if target supports it.
201 Two new YAZ client commands: . (dot, which sources a script of YAZ
202 client commands), and ! (to execute shell command.). Implemented
205 Working on Debian packages.
209 YAZ client enables named result sets only if target supports it.
211 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
213 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
214 with key="host" to get same result.
216 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
217 Function Z3950_resultset_record(s) returns references to records
218 "owned" by resultset. To become owner use Z3950_record_clone.
220 Function z_ext_record handles Extended Services. Thanks to
225 CCL Parser fix: ignore token comma when dealing with and-lists.
227 Documentation updates for COMSTACK.
229 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
230 Changed prototype Z3950_records. For some functions, int parameters
231 were changed to size_t.
233 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
236 New MARC decode/display function, marc_display_exl, which properly rejects
237 non-ISO2709 records. YAZ client uses it.
241 Fix bug: local attribute set wasn't set correctly in PQF strings.
245 * Old Z39.50 codecs no longer supported.
247 Added ZOOM C binding. See http://zoom.z3950.org/
249 Renamed states for COMSTACKs to avoid confusion with events.
251 Implemented cs_look and proper cs_rcvconnect.
253 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
255 Configure detects POSIX threads on OpenBSD.
257 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
258 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
260 When error is returned from present handler, non-surrogate diagnostic
261 is returned in present response (and fetch handler is no longer called).
263 * Minor adjustments to pquery parser (PQF). Token characters may be
264 escaped by using backslash (C-style).
266 PQF parser allows string attribute values to be specified. For @attr,
267 non-numeric characters after the equal-sign are treated as strings
268 (e.g. @attr 9=title).
270 CCL trunction character may be defined (@truncation in file)
272 * function zget_ExtendedServicesRequest sets waitAction to
273 waitIfPossible (was wait).
275 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
278 CCL operator names may be set in field definition files (CCL_bibset).
279 See ccl/bib1 for an example.
281 Fixes in ASN.1 compiler for C++ compatibility.
283 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
284 and "op_or" to avoid conflict with C++.
286 Fixed problem with GNU readline detection on Redhat 7.0.
288 Added step-size for Scan backend handler.
290 Fixed bug that made the frontend server crash when no attribute
291 set was specified for scan.
293 Front-end server automatically switches to original working directory
294 when installed as an NT service. Previously -w had to be specified to
297 Added extended attributes for retrieval module (data1), so that data1
298 records carry d1_readXML/SGML attributes. d1_read also supports
299 null-data rules ( <tag/>)
301 On UNIX when POSIX threads are available, a separate library libyazthread
302 is created. Programmers should link with that library and the yaz library
303 when using threads. The reason for the split was that some applications
304 on Linux, such as Apache, doesn't work well when using shared objects that
307 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
308 (or any frontend server) in SSL mode by specifying ssl: followed by
309 address. Only tested on UNIX.
311 Added feature for CCL module. Virtual structure s=al or s=ol generates
312 and-list and or-list respectively instead of phrase search.
316 * Added prefix "yaz_" for the functions log_init.., log_file.. and
317 log_mask_str. This was done to avoid name conflicts with other libraries
318 (such as other PHP extensions).
320 Added raw OID member for preferred record syntax (request_format_raw)
321 and returned record syntax (output_format_raw) for backend fetch method.
323 Config file yaz-config now accepts options so that it returns specific
324 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
326 Shared library support for UNIX using GNU libtool.
328 * Modified backend interface. Request/Response struct's replaced by
329 one read/write C struct. For example bend_fetchrequest and
330 bend_fetchresult have been replaced by single bend_fetch_rr struct.
331 Every handler - even search has to be registered in bend_init
332 handler. This means that the YAZ library no longer refers to
333 external functions and it makes it possible to make the whole
334 thing a single DLL/SO.
336 Added Segment handler for backend server.
338 Added Zmbol/Zebra administrative functions to YAZ client.
340 Threaded frontend server on UNIX (when POSIX Threads are available).
341 Starting the server with option -T enables multi-threading.
345 Added configure option --enable-comp/disable-comp to control use
346 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
347 located in sub directory asn.
349 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
350 in ${exec_prefix}/bin along with the other programs yaz-client and
353 GNU automake used to maintain makefiles.
357 Changed retrieval module so that we can load records with no abstract
358 syntax defined. Tagpaths in these records are fully composed of string
361 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
365 On UNIX, the generated makefile now supports a proper 'make install'.
366 The prefix can be set via GNU configure to set the install location
367 (default is /usr/local).
369 * YAZ programs client and ztest were renamed to yaz-client and
370 yaz-ztest to avoid conflicts when users install YAZ in "standard"
371 locations, such as /usr/bin,/usr/local/bin,etc.
373 * YAZ Header files were moved from include to include/yaz. YAZ Header
374 files are referred to as include <yaz/log.h> rather than <log.h>.
375 The YAZ include path (-I ..) is therefore the same as before. Programmers
376 should update their #include statements or use -Ipath/include/yaz
377 instead. The main motivation for doing this change is that YAZ header files
378 can be installed in "standard" locations /usr/include,/usr/local/include
379 without introducing conflicts, since ALL YAZ header files are stored
380 in subdirectory yaz (under /usr/include for example).
382 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
383 rather than project/workspace files. We switched because project files
384 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
387 Changed name of logging function, logf, to yaz_log, to prevent name
388 clash with some math-log functions. The YAZ header log.h defines logf
389 to yaz_log (#define) so there should be no incompatibilities by this
392 Added bend_start/bend_stop handlers for server. These handler are
393 called on start/stop of server. For windows they are called whenever
394 a service is started/stopped.
396 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
397 a fairly small ASN.1 compiler written in Tcl. The compiler is located
398 in util/yc.tcl. The auto-generated C code structures are, in a few
399 cases, incompatible with the old decoders. There are differences in the
400 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
401 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
402 The preprocessor variable ASN_COMPILED is defined when the compiled
403 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
404 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
405 wish to use the old encoders/decoders you can specify --disable-yc
408 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
409 version so that it supports both new - and old version of DB Update
411 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
412 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
413 change. The name parameter can be set to 0 in which no name is specified
414 for the construction. The macros odr_implicit and odr_explicit sets name
415 parameter to zero for the construction involved. New macros
416 odr_implicit_tag and odr_explicit_tag are similar to the others,
417 except that a name parameter is added. For programmers' that don't use
418 ODR they probably only need to change the call to z_APDU and z_External.
420 Added access control facility by interfacing the TCP wrapper library.
421 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
422 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
423 name of the daemon and enables the access control as specified in
424 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
426 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
427 den Dool <H.M.vdnDool@kub.nl>.
429 Added reference ID parameter to most functions in server API - refer
430 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
432 Changed name of ccl library to libccl.a (was ccl.a).
434 Fixed bug in decoder for Explain (Category TargetInfo).
436 Added support for GNU readline in client. Thanks to Jacob Poulsen
437 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
439 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
440 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
441 IMPLEMENTATION! This change was made to the development version before
442 the ZIG decided to retract the amendment. If any users MUST be
443 compatible with the original Update definition, PLEASE CONTACT US, and
444 we will include a separate definition corresponding to the old Update
445 ES. Note that because of the change to the ASN.1 of the
446 TaskPackageRecordStructure we cannot define a single structure that
447 will support both versions.
449 * Added const modifier to buffer parameter for some ODR/BER encoding
450 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
451 completeWAIS, odr_dumpBER.
453 Fixed bug in client.c which caused a crash when a scanResponse didn't
454 contain positionOfTerm.
456 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
457 * will cause an error in a client if a non-YAZ target sends both a
458 * list of Scan entries and non-surrogate diagnostics.
460 Retrieval module enhancements. Tag sets may be typed in the reference
461 to it. From the .abs-file the "tagset" directive takes a third optional
462 integer type for the tag set referenced. From a .tag-file the "include"
463 directive takes a third optional type as well. The old "type" directive
464 in the tag set itself is still recognized but acts as the default type
467 Backend interface change. Individual Scan terms returned from bend_scan
468 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
469 in include/backend.h.
471 Retrieval module enhancements. Multiple tag sets and attribute sets may
472 be specified in abstract syntax specs. Revised the error/warning for
473 logging messages reported by the retrieval module when reading the
476 Object Identifier system (oid_..) changed. The API is backwards
477 compatible but the oid-routines now allocates new OID's when needed.
478 Raw OID's may be specified in oid_getvalbyname.
480 YAZ now uses GNU configure to generate Makefile(s).
482 * Minor changes in some of the member names of DeleteResultSetRequest and
483 DeleteResultSetResponse. See include/proto.h.
485 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
486 and added member 'languages' in TargetInfo (which was missing).
488 Changed the way attribute sets are handled in the retrieval
489 module. These are now cached, just like the abstract syntaxes
492 Changed YAZ so that it links with compiled ASN.1.
494 Added Explain-schema definitions and mapping routines. The following
495 Explain categories have been implemented: AttributeDetails,
496 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
498 Fixed minor bug in Windows version of Server Library.
500 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
502 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
504 Added EXTERNAL: UNIverse Resource Report (non-standard).
506 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
507 ENUMERATED and SET OF.
509 * Added 'const' to some of the char pointer arguments for the
510 functions, data1_read_node, data1_getelementbytagname,
511 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
514 Fixed bug in data1_insert_taggeddata - the last_child member of
515 parent wasn't initialised.
517 * Changed data1_read_record and data1_read_node so that the supplied
518 "SGML"-buffer is read-only. In particular the resulting data1 - tree
519 doesn't refer to any parts of the "SGML"-buffer.
521 Fixed bug in server library (Windows version of statserv_remove).
523 * Changed code so that it compiles as C++. The type definition
524 of Odr_fun which is a member of Odr_arm was changed. The result is,
525 that an explicit typecast is needed for the fun pointer when
526 using Odr_arm - as in:
527 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
529 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
531 Implemented the new structured date and time definition as approved
532 by the ZIG. Added schemaId element to the specificTag in Espec-1
533 (also approved at the last ZIG). Thanks to RVDM.
535 Added some Object identifiers (RVDM).
537 Changed the Update Extended Service (RVDM).
539 Added command "refid" to client which specifies referenceId for
540 the following requests.
542 Implemented extended service handling for server. See ztest.c
543 for an example as well as backend.h. New handlers are registerd
546 * Changed interface for sort in server.
548 Added new members to statserv_options_block. It allows a server
549 to read options from another source than just the command line. Thanks
550 to Charles Woodfield.
552 * Changed definition of Z_Triple in file prt-grs.h - member boolean
553 renamed to zboolean. Some C++ compilers complained about the name.
555 Minor changes to gils.abs. Added index 's' (sort) on title
556 and date/time-last-modified.
560 Fixed bug in server library regarding inetd mode (-i). This bug
561 was introduced by release 1.4.
565 Added sort facility in client and backend server interface.
567 Fixed problem with dependencies in Makefile(s).
569 Fixed bugs for encoders/decoders of extended services and
572 Implemented sub-tree feature for schemas. Sub-trees are
573 referenced in *.abs-files. See explain.abs for an example
574 of the use of this feature.
576 Modified bib1.att; local attributes for ANY didn't include
577 ANY itself (only affects use of the retrieval module).
579 Fixed bug in plain SGML reader in function data1_read_node:
580 tags with prefix "var" was incorrectly interpreted as variants.
582 Added feature "sub-schemas" to enable references to - and definitions
583 of - group of elements.
585 * Removed member parent from type data1_element (in data1.h).
587 Implemented function odr_nullval() that returns the value of
590 * Removed member num_children from data1_node (in data1.h).
592 Made NT service interface part of the server library. The
593 function statserv_main uses the NT service when required and
594 calls the statserv_start / statserv_close routines.
596 Routine zget_SearchRequest and zget_PresentRequest fills
597 resultSetName/Id member with "default" instead of "Default".
599 Fixed memory leak in server. Request queue member wasn't freed.
601 Fixed nmem_exit so that memory is freed.
605 Revised the CCL parser utility to be thread safe.
607 Added function, oid_ent_to_oid, to replace the function
608 oid_getoidbyent, which is not thread safe.
610 * Added nmem_init and nmem_exit to initialize and release
611 NMEM resources. Function nmem_init should be called once in the
612 initial thread before NMEM/ODR is used. statserv.c and client.c
613 have been changed accordingly. The change was necessary to make
614 NMEM thread safe. The NMEM memory pool is shared amongst threads
615 in a process. Unix-based applications will still work fine without
618 Added NT Services interface for the the Z39.50 (statserv) Server.
619 Refer to the ztest.c source on the usage.
621 Windows 95/NT port using MSVC5.0. Project files are included in the
624 * Defined new 'global' handle for the retrieval (data1) system. The
625 new handled, data1_handle, describes the state of the data1 system.
626 This handle is passed as first argument to virtually all
627 data1 related routines. The functions data1_create and data1_destroy
628 creates and destroys a data1 handle respectively.
630 Added ODR encode stream member to all backend request structures
631 init, search, scan etc. This stream should be used to allocate all
632 memory used for the response when thread safe operation is needed.
634 Changed the comstack utility, cs_addstr, to be thread safe. The
635 returned hostname string returned by the function is now part the
638 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
639 function. The cs_straddr takes a COMSTACK handle as argument, so this
640 function must be used after cs_create and before bind/connect.
641 This function is thread safe.
643 Moved test server to 'ztest' directory - generic server code still
644 in 'server' directory.
646 Made prefix query (pquery.c) utility thread safe.
648 Added new function modifier YAZ_EXPORT to 'export' public DLL
649 functions when using windows (see include/yconfig.h).
651 Added definitions to the OID database (util/oid.c) (RVDM).
653 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
655 Added call to ccl_rpn_delete in client program.
657 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
658 release of RPN structure.
660 Added support for C++, headers uses extern "C" for public definitions.
661 With input from RVDM.
663 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
664 Thanks to Ronald van der Meer (RVDM).
666 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
668 Added support for private extensions to the OID database
669 (oid_setprivateoids()). Thanks to RVDM.
671 Added optional, physical ANY (key replication)
673 Fixed null-reference problem in GRS-1 output filter.
675 Proximity operator added to Prefix Query Format (PQF).
677 In test client command "base" accepts multiple databases.
679 Fixed bug in cs_close stack that caused trouble with WINSOCK.

702 --- 1.2 1996/6/10 (1st anniversary release)
704 Added Summary record syntax. Lightly tested.
706 Added OPAC record syntax. Untested.
708 Added ResourceReport service encoders/decoders. Untested.
710 Fixed bug in z_Unit - wrong tagging on unitSystem.
712 Fixed bug in the DiagRecs decoder.
714 Added options for max PDU size and session timeout to frontend-server.
716 Added documentation of query-language parsers and other supporting utilities.
718 [frontend-server] Added Attribute set to the bend_scanrequest API.
720 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
721 surrogate diagnostics were generated.
723 [retrieval] Allow multiple local values for attribute.
725 [retrieval] Allow multiple attributes per element in .abs files. index type.
727 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
731 Minor changes, mostly specific to Zebra's requirements (retrieval)
735 Repaired bug in frontend server when running multiple listening
736 endpoints in dynamic mode.
738 z_External() now won't break if a known, ASN.1 value comes encapsulated
739 in an octet-string. The value will pass through unmodified in an Odr_oct.
741 Added a bit of code to the demo client to decode & display
742 ASN.1-structured records represented in the octet-aligned branch of
743 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
745 Added z_ext_getentbyref() to the ASN module. Doc updated.
747 * Completed the SCAN definition in the ASN module. This may break SCAN
748 code based on older YAZ-versions at compile-time. The fix is easy -
751 * Added 'displayTerm' and OtherInformation to the TermInfo structure
752 under the SCAN definition. Remember to initialize this, server-people.
754 Comstack should now support the WAIS protocol in TCP/IP mode. Note
755 that this does not extend to ODR and ASN.
757 Comstack allows insertion of established socket (primarily for
758 inetd-operation of servers). Doc updated.
760 Front-end server can now start from the inetd in TCP mode. Doc
767 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
768 the rank and record number.
770 Adjustments to the frontend server.
772 Fixed diagnostic BER dumper. It ignored the file argument.
776 Various changes to retrieval module.
778 Changed the union discriminators of the protocol files from enums to
779 ints paired with #defines.
781 *Changed oident.class to oident.oclass to avoid a reserved word in C++
784 *Changed operator in the RPN structure to 'roperator', again to avoid a
787 Fixed problems in Explain decoders/encoders.
791 Memory bug in log module fixed.
795 Occasional malloc() of 0 bytes fixed in d1_espec.c.
797 Bug in Explain DatabaseInfo module fixed.
799 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
803 The shift to v1.0 signals that we now consider the *core* functionality
804 of YAZ reasonably stable (the core being more or less equivalent to
805 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
806 tested (Explain not at all - though that will happen soonish).
808 Minor changes to code to support Windows port.
810 Various minor changes after we're getting to use GRS-1 & co. more.
812 Added Espec-1 format.
814 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
815 of the protocol and it cannot be selected when encoding (maps into 'string'
816 when decoding). Needed to talk to some servers.
818 Demo client can request simple element set names.
820 Added Diagnostic Format encoders/decoders.
822 Added simple Close handling to frontend server (no hooks for resource
823 reporting yet), and demonstration client.
825 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
829 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
830 handled incorrectly when records were requested in the searchResponse. This
831 will only affect you if you use the frontend-server.
833 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
834 Test-client will ask for and print GRS1. Ztest will return dummy records
837 Added Explain encoders/decoders to the service-level API. Untested.
839 Added Extended Services: Item Order encoders and decoders to the Service-
840 level API. Untested. We could use a recent copy of the pertinent bits
841 of the ILL protocol to add those bits.
843 Added diagnostic format 1 encoders/decoders to the service-level API.
846 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
847 odr_cons.c, which causes a more correct output.
849 Fixed handling of searchRequest in frontend server. NextResultSetPosition
850 was always set to 0 when no records were requested in the searchRequest.
852 * Added better external-handling. This shouldn't harm old code that
853 *encodes* externals. It can break code that looks for a
854 'single-ASN1-type' representation, since those types that are known
855 are now decoded immediately. Look at the SUTRS sample code in
856 seshigh.c and client.c. Documentation updated.
858 Handling of structured records in bend_fetchresponse. Length -1 marks
859 structured record, type is deduced from format field.
862 Fairly quick maintenance release to add SUTRS support.
864 Fixed handling of SUTRS records in the demonstration client.
866 * Added format field to the bend_fetchrequest and bend_fetchresponce
867 structures of the backend API (frontend server). When the record is
868 returned, the value of the format field is mapped to an OID. The
869 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
870 of the record. The special value VAL_NONE in the bend_request means
871 that no specific format was requested by the client. Documentation
872 updated accordingly. Test server (ztest) will return a fixed dummy
873 SUTRS record if your client requests SUTRS.
875 Documentation updated accordingly.
877 You can now set external libraries and RANLIB support in the top-level
881 First public release.
