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

122 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
126 New YAZ client features: Command completion and new commands:
127 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
128 Code provided by Jacob Poulsen.
130 New call oid_trav, that visits all registered OIDs via callback.
132 Function ZOOM_record_get now returns const char pointer rather than
133 void pointer. It saves a lot of type casts.
135 For YAZ client, command "auth" now allows you to set authentication
136 in IdPass style. It is enabled when three tokens are given - order
137 is user, group and password.
139 Fix memory leaks in MARC record handling for ZOOM.
141 New option for YAZ client, -k <kilobytes> that sets
142 maximum record size. Similar to -k option for generic frontend
143 server and yaz-ztest.
145 More fixes for scan. Non-zero stepSize handled. OID's fixes.
147 Prefix query parser reports "fail" when bad attribute set is given.
149 Fix in MARC decoder. Proximity logging. Fix for attribute set
150 in scan handler for server. Patches by Shigeru Ishida.
152 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
155 Configure option --with-openssl=<dir> now works when a directory is
156 specified. Patch provided by Morten Bøgeskov.
158 New option for YAZ client, -u <auth>, that sets authentication.
160 ZOOM fix: error information was sometimes "missing", since error
161 was cleared/reset too when it shouldn't.
163 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
167 Scan for ZOOM API. New object ZOOM_scanset. New functions
168 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
169 ZOOM_scanset_destroy.
171 New ZOOM function, ZOOM_connection_last_event, that returns type
172 of last event (such as "receive data", "send data", "apdu received",
175 New ZOOM option, schema, that specifies shema OID for retrieval.
177 New CCL feature. Qualifiers can be aliases for one or more
178 other qualifiers (if more than one is given, OR is used).
180 ZOOM uses named result sets if target supports it.
182 Two new YAZ client commands: . (dot, which sources a script of YAZ
183 client commands), and ! (to execute shell command.). Implemented
186 Working on Debian packages.
190 YAZ client enables named result sets only if target supports it.
192 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
194 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
195 with key="host" to get same result.
197 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
198 Function Z3950_resultset_record(s) returns references to records
199 "owned" by resultset. To become owner use Z3950_record_clone.
201 Function z_ext_record handles Extended Services. Thanks to
206 CCL Parser fix: ignore token comma when dealing with and-lists.
208 Documentation updates for COMSTACK.
210 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
211 Changed prototype Z3950_records. For some functions, int parameters
212 were changed to size_t.
214 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
217 New MARC decode/display function, marc_display_exl, which properly rejects
218 non-ISO2709 records. YAZ client uses it.
222 Fix bug: local attribute set wasn't set correctly in PQF strings.
226 * Old Z39.50 codecs no longer supported.
228 Added ZOOM C binding. See http://zoom.z3950.org/
230 Renamed states for COMSTACKs to avoid confusion with events.
232 Implemented cs_look and proper cs_rcvconnect.
234 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
236 Configure detects POSIX threads on OpenBSD.
238 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
239 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
241 When error is returned from present handler, non-surrogate diagnostic
242 is returned in present response (and fetch handler is no longer called).
244 * Minor adjustments to pquery parser (PQF). Token characters may be
245 escaped by using backslash (C-style).
247 PQF parser allows string attribute values to be specified. For @attr,
248 non-numeric characters after the equal-sign are treated as strings
249 (e.g. @attr 9=title).
251 CCL trunction character may be defined (@truncation in file)
253 * function zget_ExtendedServicesRequest sets waitAction to
254 waitIfPossible (was wait).
256 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
259 CCL operator names may be set in field definition files (CCL_bibset).
260 See ccl/bib1 for an example.
262 Fixes in ASN.1 compiler for C++ compatibility.
264 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
265 and "op_or" to avoid conflict with C++.
267 Fixed problem with GNU readline detection on Redhat 7.0.
269 Added step-size for Scan backend handler.
271 Fixed bug that made the frontend server crash when no attribute
272 set was specified for scan.
274 Front-end server automatically switches to original working directory
275 when installed as an NT service. Previously -w had to be specified to
278 Added extended attributes for retrieval module (data1), so that data1
279 records carry d1_readXML/SGML attributes. d1_read also supports
280 null-data rules ( <tag/>)
282 On UNIX when POSIX threads are available, a separate library libyazthread
283 is created. Programmers should link with that library and the yaz library
284 when using threads. The reason for the split was that some applications
285 on Linux, such as Apache, doesn't work well when using shared objects that
288 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
289 (or any frontend server) in SSL mode by specifying ssl: followed by
290 address. Only tested on UNIX.
292 Added feature for CCL module. Virtual structure s=al or s=ol generates
293 and-list and or-list respectively instead of phrase search.
297 * Added prefix "yaz_" for the functions log_init.., log_file.. and
298 log_mask_str. This was done to avoid name conflicts with other libraries
299 (such as other PHP extensions).
301 Added raw OID member for preferred record syntax (request_format_raw)
302 and returned record syntax (output_format_raw) for backend fetch method.
304 Config file yaz-config now accepts options so that it returns specific
305 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
307 Shared library support for UNIX using GNU libtool.
309 * Modified backend interface. Request/Response struct's replaced by
310 one read/write C struct. For example bend_fetchrequest and
311 bend_fetchresult have been replaced by single bend_fetch_rr struct.
312 Every handler - even search has to be registered in bend_init
313 handler. This means that the YAZ library no longer refers to
314 external functions and it makes it possible to make the whole
315 thing a single DLL/SO.
317 Added Segment handler for backend server.
319 Added Zmbol/Zebra administrative functions to YAZ client.
321 Threaded frontend server on UNIX (when POSIX Threads are available).
322 Starting the server with option -T enables multi-threading.
326 Added configure option --enable-comp/disable-comp to control use
327 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
328 located in sub directory asn.
330 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
331 in ${exec_prefix}/bin along with the other programs yaz-client and
334 GNU automake used to maintain makefiles.
338 Changed retrieval module so that we can load records with no abstract
339 syntax defined. Tagpaths in these records are fully composed of string
342 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
346 On UNIX, the generated makefile now supports a proper 'make install'.
347 The prefix can be set via GNU configure to set the install location
348 (default is /usr/local).
350 * YAZ programs client and ztest were renamed to yaz-client and
351 yaz-ztest to avoid conflicts when users install YAZ in "standard"
352 locations, such as /usr/bin,/usr/local/bin,etc.
354 * YAZ Header files were moved from include to include/yaz. YAZ Header
355 files are referred to as include <yaz/log.h> rather than <log.h>.
356 The YAZ include path (-I ..) is therefore the same as before. Programmers
357 should update their #include statements or use -Ipath/include/yaz
358 instead. The main motivation for doing this change is that YAZ header files
359 can be installed in "standard" locations /usr/include,/usr/local/include
360 without introducing conflicts, since ALL YAZ header files are stored
361 in subdirectory yaz (under /usr/include for example).
363 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
364 rather than project/workspace files. We switched because project files
365 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
368 Changed name of logging function, logf, to yaz_log, to prevent name
369 clash with some math-log functions. The YAZ header log.h defines logf
370 to yaz_log (#define) so there should be no incompatibilities by this
373 Added bend_start/bend_stop handlers for server. These handler are
374 called on start/stop of server. For windows they are called whenever
375 a service is started/stopped.
377 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
378 a fairly small ASN.1 compiler written in Tcl. The compiler is located
379 in util/yc.tcl. The auto-generated C code structures are, in a few
380 cases, incompatible with the old decoders. There are differences in the
381 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
382 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
383 The preprocessor variable ASN_COMPILED is defined when the compiled
384 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
385 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
386 wish to use the old encoders/decoders you can specify --disable-yc
389 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
390 version so that it supports both new - and old version of DB Update
392 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
393 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
394 change. The name parameter can be set to 0 in which no name is specified
395 for the construction. The macros odr_implicit and odr_explicit sets name
396 parameter to zero for the construction involved. New macros
397 odr_implicit_tag and odr_explicit_tag are similar to the others,
398 except that a name parameter is added. For programmers' that don't use
399 ODR they probably only need to change the call to z_APDU and z_External.
401 Added access control facility by interfacing the TCP wrapper library.
402 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
403 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
404 name of the daemon and enables the access control as specified in
405 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
407 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
408 den Dool <H.M.vdnDool@kub.nl>.
410 Added reference ID parameter to most functions in server API - refer
411 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
413 Changed name of ccl library to libccl.a (was ccl.a).
415 Fixed bug in decoder for Explain (Category TargetInfo).
417 Added support for GNU readline in client. Thanks to Jacob Poulsen
418 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
420 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
421 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
422 IMPLEMENTATION! This change was made to the development version before
423 the ZIG decided to retract the amendment. If any users MUST be
424 compatible with the original Update definition, PLEASE CONTACT US, and
425 we will include a separate definition corresponding to the old Update
426 ES. Note that because of the change to the ASN.1 of the
427 TaskPackageRecordStructure we cannot define a single structure that
428 will support both versions.
430 * Added const modifier to buffer parameter for some ODR/BER encoding
431 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
432 completeWAIS, odr_dumpBER.
434 Fixed bug in client.c which caused a crash when a scanResponse didn't
435 contain positionOfTerm.
437 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
438 * will cause an error in a client if a non-YAZ target sends both a
439 * list of Scan entries and non-surrogate diagnostics.
441 Retrieval module enhancements. Tag sets may be typed in the reference
442 to it. From the .abs-file the "tagset" directive takes a third optional
443 integer type for the tag set referenced. From a .tag-file the "include"
444 directive takes a third optional type as well. The old "type" directive
445 in the tag set itself is still recognized but acts as the default type
448 Backend interface change. Individual Scan terms returned from bend_scan
449 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
450 in include/backend.h.
452 Retrieval module enhancements. Multiple tag sets and attribute sets may
453 be specified in abstract syntax specs. Revised the error/warning for
454 logging messages reported by the retrieval module when reading the
457 Object Identifier system (oid_..) changed. The API is backwards
458 compatible but the oid-routines now allocates new OID's when needed.
459 Raw OID's may be specified in oid_getvalbyname.
461 YAZ now uses GNU configure to generate Makefile(s).
463 * Minor changes in some of the member names of DeleteResultSetRequest and
464 DeleteResultSetResponse. See include/proto.h.
466 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
467 and added member 'languages' in TargetInfo (which was missing).
469 Changed the way attribute sets are handled in the retrieval
470 module. These are now cached, just like the abstract syntaxes
473 Changed YAZ so that it links with compiled ASN.1.
475 Added Explain-schema definitions and mapping routines. The following
476 Explain categories have been implemented: AttributeDetails,
477 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
479 Fixed minor bug in Windows version of Server Library.
481 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
483 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
485 Added EXTERNAL: UNIverse Resource Report (non-standard).
487 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
488 ENUMERATED and SET OF.
490 * Added 'const' to some of the char pointer arguments for the
491 functions, data1_read_node, data1_getelementbytagname,
492 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
495 Fixed bug in data1_insert_taggeddata - the last_child member of
496 parent wasn't initialised.
498 * Changed data1_read_record and data1_read_node so that the supplied
499 "SGML"-buffer is read-only. In particular the resulting data1 - tree
500 doesn't refer to any parts of the "SGML"-buffer.
502 Fixed bug in server library (Windows version of statserv_remove).
504 * Changed code so that it compiles as C++. The type definition
505 of Odr_fun which is a member of Odr_arm was changed. The result is,
506 that an explicit typecast is needed for the fun pointer when
507 using Odr_arm - as in:
508 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
510 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
512 Implemented the new structured date and time definition as approved
513 by the ZIG. Added schemaId element to the specificTag in Espec-1
514 (also approved at the last ZIG). Thanks to RVDM.
516 Added some Object identifiers (RVDM).
518 Changed the Update Extended Service (RVDM).
520 Added command "refid" to client which specifies referenceId for
521 the following requests.
523 Implemented extended service handling for server. See ztest.c
524 for an example as well as backend.h. New handlers are registerd
527 * Changed interface for sort in server.
529 Added new members to statserv_options_block. It allows a server
530 to read options from another source than just the command line. Thanks
531 to Charles Woodfield.
533 * Changed definition of Z_Triple in file prt-grs.h - member boolean
534 renamed to zboolean. Some C++ compilers complained about the name.
536 Minor changes to gils.abs. Added index 's' (sort) on title
537 and date/time-last-modified.
541 Fixed bug in server library regarding inetd mode (-i). This bug
542 was introduced by release 1.4.
546 Added sort facility in client and backend server interface.
548 Fixed problem with dependencies in Makefile(s).
550 Fixed bugs for encoders/decoders of extended services and
553 Implemented sub-tree feature for schemas. Sub-trees are
554 referenced in *.abs-files. See explain.abs for an example
555 of the use of this feature.
557 Modified bib1.att; local attributes for ANY didn't include
558 ANY itself (only affects use of the retrieval module).
560 Fixed bug in plain SGML reader in function data1_read_node:
561 tags with prefix "var" was incorrectly interpreted as variants.
563 Added feature "sub-schemas" to enable references to - and definitions
564 of - group of elements.
566 * Removed member parent from type data1_element (in data1.h).
568 Implemented function odr_nullval() that returns the value of
571 * Removed member num_children from data1_node (in data1.h).
573 Made NT service interface part of the server library. The
574 function statserv_main uses the NT service when required and
575 calls the statserv_start / statserv_close routines.
577 Routine zget_SearchRequest and zget_PresentRequest fills
578 resultSetName/Id member with "default" instead of "Default".
580 Fixed memory leak in server. Request queue member wasn't freed.
582 Fixed nmem_exit so that memory is freed.
586 Revised the CCL parser utility to be thread safe.
588 Added function, oid_ent_to_oid, to replace the function
589 oid_getoidbyent, which is not thread safe.
591 * Added nmem_init and nmem_exit to initialize and release
592 NMEM resources. Function nmem_init should be called once in the
593 initial thread before NMEM/ODR is used. statserv.c and client.c
594 have been changed accordingly. The change was necessary to make
595 NMEM thread safe. The NMEM memory pool is shared amongst threads
596 in a process. Unix-based applications will still work fine without
599 Added NT Services interface for the the Z39.50 (statserv) Server.
600 Refer to the ztest.c source on the usage.
602 Windows 95/NT port using MSVC5.0. Project files are included in the
605 * Defined new 'global' handle for the retrieval (data1) system. The
606 new handled, data1_handle, describes the state of the data1 system.
607 This handle is passed as first argument to virtually all
608 data1 related routines. The functions data1_create and data1_destroy
609 creates and destroys a data1 handle respectively.
611 Added ODR encode stream member to all backend request structures
612 init, search, scan etc. This stream should be used to allocate all
613 memory used for the response when thread safe operation is needed.
615 Changed the comstack utility, cs_addstr, to be thread safe. The
616 returned hostname string returned by the function is now part the
619 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
620 function. The cs_straddr takes a COMSTACK handle as argument, so this
621 function must be used after cs_create and before bind/connect.
622 This function is thread safe.
624 Moved test server to 'ztest' directory - generic server code still
625 in 'server' directory.
627 Made prefix query (pquery.c) utility thread safe.
629 Added new function modifier YAZ_EXPORT to 'export' public DLL
630 functions when using windows (see include/yconfig.h).
632 Added definitions to the OID database (util/oid.c) (RVDM).
634 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
636 Added call to ccl_rpn_delete in client program.
638 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
639 release of RPN structure.
641 Added support for C++, headers uses extern "C" for public definitions.
642 With input from RVDM.
644 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
645 Thanks to Ronald van der Meer (RVDM).
647 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
649 Added support for private extensions to the OID database
650 (oid_setprivateoids()). Thanks to RVDM.
652 Added optional, physical ANY (key replication)
654 Fixed null-reference problem in GRS-1 output filter.
656 Proximity operator added to Prefix Query Format (PQF).
658 In test client command "base" accepts multiple databases.
660 Fixed bug in cs_close stack that caused trouble with WINSOCK.
664 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
666 Smallish bug-fixes in the new encoders/decoders (explain).
668 Bug fixed in DeleteRequest.
670 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
672 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
674 Added SOIF syntax (using private OID for now) to retrieval module and client.
676 Added Update extended service.
678 Added SearchResult-1 additional info structure.
680 Added optional CCL (ISO8777) interpreter as separate module. Available
683 --- 1.2 1996/6/10 (1st anniversary release)
685 Added Summary record syntax. Lightly tested.
687 Added OPAC record syntax. Untested.
689 Added ResourceReport service encoders/decoders. Untested.
691 Fixed bug in z_Unit - wrong tagging on unitSystem.
693 Fixed bug in the DiagRecs decoder.
695 Added options for max PDU size and session timeout to frontend-server.
697 Added documentation of query-language parsers and other supporting utilities.
699 [frontend-server] Added Attribute set to the bend_scanrequest API.
701 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
702 surrogate diagnostics were generated.
704 [retrieval] Allow multiple local values for attribute.
706 [retrieval] Allow multiple attributes per element in .abs files. index type.
708 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
712 Minor changes, mostly specific to Zebra's requirements (retrieval)
716 Repaired bug in frontend server when running multiple listening
717 endpoints in dynamic mode.
719 z_External() now won't break if a known, ASN.1 value comes encapsulated
720 in an octet-string. The value will pass through unmodified in an Odr_oct.
722 Added a bit of code to the demo client to decode & display
723 ASN.1-structured records represented in the octet-aligned branch of
724 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
726 Added z_ext_getentbyref() to the ASN module. Doc updated.
728 * Completed the SCAN definition in the ASN module. This may break SCAN
729 code based on older YAZ-versions at compile-time. The fix is easy -
732 * Added 'displayTerm' and OtherInformation to the TermInfo structure
733 under the SCAN definition. Remember to initialize this, server-people.
735 Comstack should now support the WAIS protocol in TCP/IP mode. Note
736 that this does not extend to ODR and ASN.
738 Comstack allows insertion of established socket (primarily for
739 inetd-operation of servers). Doc updated.
741 Front-end server can now start from the inetd in TCP mode. Doc
748 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
749 the rank and record number.
751 Adjustments to the frontend server.
753 Fixed diagnostic BER dumper. It ignored the file argument.
757 Various changes to retrieval module.
759 Changed the union discriminators of the protocol files from enums to
760 ints paired with #defines.
762 *Changed oident.class to oident.oclass to avoid a reserved word in C++
765 *Changed operator in the RPN structure to 'roperator', again to avoid a
768 Fixed problems in Explain decoders/encoders.
772 Memory bug in log module fixed.
776 Occasional malloc() of 0 bytes fixed in d1_espec.c.
778 Bug in Explain DatabaseInfo module fixed.
780 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
784 The shift to v1.0 signals that we now consider the *core* functionality
785 of YAZ reasonably stable (the core being more or less equivalent to
786 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
787 tested (Explain not at all - though that will happen soonish).
789 Minor changes to code to support Windows port.
791 Various minor changes after we're getting to use GRS-1 & co. more.
793 Added Espec-1 format.
795 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
796 of the protocol and it cannot be selected when encoding (maps into 'string'
797 when decoding). Needed to talk to some servers.
799 Demo client can request simple element set names.
801 Added Diagnostic Format encoders/decoders.
803 Added simple Close handling to frontend server (no hooks for resource
804 reporting yet), and demonstration client.
806 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
810 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
811 handled incorrectly when records were requested in the searchResponse. This
812 will only affect you if you use the frontend-server.
814 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
815 Test-client will ask for and print GRS1. Ztest will return dummy records
818 Added Explain encoders/decoders to the service-level API. Untested.
820 Added Extended Services: Item Order encoders and decoders to the Service-
821 level API. Untested. We could use a recent copy of the pertinent bits
822 of the ILL protocol to add those bits.
824 Added diagnostic format 1 encoders/decoders to the service-level API.
827 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
828 odr_cons.c, which causes a more correct output.
830 Fixed handling of searchRequest in frontend server. NextResultSetPosition
831 was always set to 0 when no records were requested in the searchRequest.
833 * Added better external-handling. This shouldn't harm old code that
834 *encodes* externals. It can break code that looks for a
835 'single-ASN1-type' representation, since those types that are known
836 are now decoded immediately. Look at the SUTRS sample code in
837 seshigh.c and client.c. Documentation updated.
839 Handling of structured records in bend_fetchresponse. Length -1 marks
840 structured record, type is deduced from format field.
843 Fairly quick maintenance release to add SUTRS support.
845 Fixed handling of SUTRS records in the demonstration client.
847 * Added format field to the bend_fetchrequest and bend_fetchresponce
848 structures of the backend API (frontend server). When the record is
849 returned, the value of the format field is mapped to an OID. The
850 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
851 of the record. The special value VAL_NONE in the bend_request means
852 that no specific format was requested by the client. Documentation
853 updated accordingly. Test server (ztest) will return a fixed dummy
854 SUTRS record if your client requests SUTRS.
856 Documentation updated accordingly.
858 You can now set external libraries and RANLIB support in the top-level
862 First public release.
