1 Possible compatibility problems with earlier versions marked with '*'.
5 PQF parser rejects bad queries - including those with extra
6 characters in them. PQF parser used to silently ignore that.
7 Cleaner API for PQF added, which allows you to get detailed
8 error information for bad queries (see yaz/pquery.h).
10 Implemented mini iconv library supporting conversions between
11 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
13 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
17 Fixed ZOOM C record cache so that preferredRecordSyntax and
18 elementSetName is used to check for already fetched records.
22 Added three members in bend_initrequest structure to facilitate
23 character set negotiation.
25 Fixed a bug in frontend server that could cause indefinite
26 loops under rare conditions.
28 Revised character set utilities (charneg.h) so that encoding
29 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
31 For PQF, directive @term <type> sets term type for Scan/Search.
32 Here <type> is general, string, numeric, null. The term type
33 is inherited - just like @attr.
35 New call odr_set_charset that sets character set conversion for
36 international-strings on a ODR stream. Prototype is:
37 int odr_set_charset(ODR o, const char *to, const char *from);
38 The InternationalString is still represented as C string in YAZ
39 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
40 won't). On the protocol level, you can use any encoding.
42 Support for UNIX sockets in ZOOM.
44 Solaris recv sometimes returns errno == ENOENT. It is treated as
45 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
47 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
48 both client and server. Code by Morten Bøgeskov.
52 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
53 that they can be used directly from Visual Basic. You must recompile
54 your windows APP if you're using ZOOM.
56 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
57 Commands "lang" and "charset" sets language and character set respectively.
58 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
59 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
61 Attributes from multiple CCL fields may be OR'ed rather than merged
62 using directive "@field or". Fields are still merged by default -
63 equivalent to "@field merge".
65 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
68 Fixed bug in zget for parameter ExtendedServicesResponse.
74 Added PQF feature: '@attr type=value' may be written as '@type=value'.
76 Client displays USR.1:SearchResult-1 (hits per term).
78 Additional Search Info for search in Generic Frontend Server.
80 Fixed CCL parsing of "field=s".
82 WIN32 installer - using the excellent NSIS software from nullsoft.
84 Fixed CCL parsing of "field = - <number>".
86 Added function yaz_marc_decode that decodes MARC for line mode
87 display or XML (similar to that used by JZKit).
89 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
90 Z39.50. But ISO/ILL was, however.
92 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
93 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

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