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

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