1 Possible compatibility problems with earlier versions marked with '*'.
5 Added three members in bend_initrequest structure to facilitate
6 character set negotiation.
8 Fixed a bug in frontend server that could cause indefinite
9 loops under rare conditions.
11 Revised character set utilities (charneg.h) so that encoding
12 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
14 For PQF, directive @term <type> sets term type for Scan/Search.
15 Here <type> is general, string, numeric, null. The term type
16 is inherited - just like @attr.
18 New call odr_set_charset that sets character set conversion for
19 international-strings on a ODR stream. Prototype is:
20 int odr_set_charset(ODR o, const char *to, const char *from);
21 The InternationalString is still represented as C string in YAZ
22 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
23 won't). On the protocol level, you can use any encoding.
25 Support for UNIX sockets in ZOOM.
27 Solaris recv sometimes returns errno == ENOENT. It is treated as
28 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
30 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
31 both client and server. Code by Morten Bøgeskov.
35 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
36 that they can be used directly from Visual Basic. You must recompile
37 your windows APP if you're using ZOOM.
39 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
40 Commands "lang" and "charset" sets language and character set respectively.
41 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
42 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
44 Attributes from multiple CCL fields may be OR'ed rather than merged
45 using directive "@field or". Fields are still merged by default -
46 equivalent to "@field merge".
48 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
51 Fixed bug in zget for parameter ExtendedServicesResponse.
57 Added PQF feature: '@attr type=value' may be written as '@type=value'.
59 Client displays USR.1:SearchResult-1 (hits per term).
61 Additional Search Info for search in Generic Frontend Server.
63 Fixed CCL parsing of "field=s".
65 WIN32 installer - using the excellent NSIS software from nullsoft.
67 Fixed CCL parsing of "field = - <number>".
69 Added function yaz_marc_decode that decodes MARC for line mode
70 display or XML (similar to that used by JZKit).
72 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
73 Z39.50. But ISO/ILL was, however.
75 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
76 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
78 http://lcweb.loc.gov/z3950/agency/amend/am2.html
79 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
83 New YAZ client features: Command completion and new commands:
84 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
85 Code provided by Jacob Poulsen.
87 New call oid_trav, that visits all registered OIDs via callback.
89 Function ZOOM_record_get now returns const char pointer rather than
90 void pointer. It saves a lot of type casts.
92 For YAZ client, command "auth" now allows you to set authentication
93 in IdPass style. It is enabled when three tokens are given - order
94 is user, group and password.
96 Fix memory leaks in MARC record handling for ZOOM.
98 New option for YAZ client, -k <kilobytes> that sets
99 maximum record size. Similar to -k option for generic frontend
100 server and yaz-ztest.
102 More fixes for scan. Non-zero stepSize handled. OID's fixes.
104 Prefix query parser reports "fail" when bad attribute set is given.
106 Fix in MARC decoder. Proximity logging. Fix for attribute set
107 in scan handler for server. Patches by Shigeru Ishida.
109 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
112 Configure option --with-openssl=<dir> now works when a directory is
113 specified. Patch provided by Morten Bøgeskov.
115 New option for YAZ client, -u <auth>, that sets authentication.
117 ZOOM fix: error information was sometimes "missing", since error
118 was cleared/reset too when it shouldn't.
120 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
124 Scan for ZOOM API. New object ZOOM_scanset. New functions
125 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
126 ZOOM_scanset_destroy.
128 New ZOOM function, ZOOM_connection_last_event, that returns type
129 of last event (such as "receive data", "send data", "apdu received",
132 New ZOOM option, schema, that specifies shema OID for retrieval.
134 New CCL feature. Qualifiers can be aliases for one or more
135 other qualifiers (if more than one is given, OR is used).
137 ZOOM uses named result sets if target supports it.
139 Two new YAZ client commands: . (dot, which sources a script of YAZ
140 client commands), and ! (to execute shell command.). Implemented
143 Working on Debian packages.
147 YAZ client enables named result sets only if target supports it.
149 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
151 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
152 with key="host" to get same result.
154 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
155 Function Z3950_resultset_record(s) returns references to records
156 "owned" by resultset. To become owner use Z3950_record_clone.
158 Function z_ext_record handles Extended Services. Thanks to
163 CCL Parser fix: ignore token comma when dealing with and-lists.
165 Documentation updates for COMSTACK.
167 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
168 Changed prototype Z3950_records. For some functions, int parameters
169 were changed to size_t.
171 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
174 New MARC decode/display function, marc_display_exl, which properly rejects
175 non-ISO2709 records. YAZ client uses it.
179 Fix bug: local attribute set wasn't set correctly in PQF strings.
183 * Old Z39.50 codecs no longer supported.
185 Added ZOOM C binding. See http://zoom.z3950.org/
187 Renamed states for COMSTACKs to avoid confusion with events.
189 Implemented cs_look and proper cs_rcvconnect.
191 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
193 Configure detects POSIX threads on OpenBSD.
195 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
196 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
198 When error is returned from present handler, non-surrogate diagnostic
199 is returned in present response (and fetch handler is no longer called).
201 * Minor adjustments to pquery parser (PQF). Token characters may be
202 escaped by using backslash (C-style).
204 PQF parser allows string attribute values to be specified. For @attr,
205 non-numeric characters after the equal-sign are treated as strings
206 (e.g. @attr 9=title).
208 CCL trunction character may be defined (@truncation in file)
210 * function zget_ExtendedServicesRequest sets waitAction to
211 waitIfPossible (was wait).
213 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
216 CCL operator names may be set in field definition files (CCL_bibset).
217 See ccl/bib1 for an example.
219 Fixes in ASN.1 compiler for C++ compatibility.
221 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
222 and "op_or" to avoid conflict with C++.
224 Fixed problem with GNU readline detection on Redhat 7.0.
226 Added step-size for Scan backend handler.
228 Fixed bug that made the frontend server crash when no attribute
229 set was specified for scan.
231 Front-end server automatically switches to original working directory
232 when installed as an NT service. Previously -w had to be specified to
235 Added extended attributes for retrieval module (data1), so that data1
236 records carry d1_readXML/SGML attributes. d1_read also supports
237 null-data rules ( <tag/>)
239 On UNIX when POSIX threads are available, a separate library libyazthread
240 is created. Programmers should link with that library and the yaz library
241 when using threads. The reason for the split was that some applications
242 on Linux, such as Apache, doesn't work well when using shared objects that
245 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
246 (or any frontend server) in SSL mode by specifying ssl: followed by
247 address. Only tested on UNIX.
249 Added feature for CCL module. Virtual structure s=al or s=ol generates
250 and-list and or-list respectively instead of phrase search.
254 * Added prefix "yaz_" for the functions log_init.., log_file.. and
255 log_mask_str. This was done to avoid name conflicts with other libraries
256 (such as other PHP extensions).
258 Added raw OID member for preferred record syntax (request_format_raw)
259 and returned record syntax (output_format_raw) for backend fetch method.
261 Config file yaz-config now accepts options so that it returns specific
262 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
264 Shared library support for UNIX using GNU libtool.
266 * Modified backend interface. Request/Response struct's replaced by
267 one read/write C struct. For example bend_fetchrequest and
268 bend_fetchresult have been replaced by single bend_fetch_rr struct.
269 Every handler - even search has to be registered in bend_init
270 handler. This means that the YAZ library no longer refers to
271 external functions and it makes it possible to make the whole
272 thing a single DLL/SO.
274 Added Segment handler for backend server.
276 Added Zmbol/Zebra administrative functions to YAZ client.
278 Threaded frontend server on UNIX (when POSIX Threads are available).
279 Starting the server with option -T enables multi-threading.
283 Added configure option --enable-comp/disable-comp to control use
284 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
285 located in sub directory asn.
287 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
288 in ${exec_prefix}/bin along with the other programs yaz-client and
291 GNU automake used to maintain makefiles.
295 Changed retrieval module so that we can load records with no abstract
296 syntax defined. Tagpaths in these records are fully composed of string
299 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
303 On UNIX, the generated makefile now supports a proper 'make install'.
304 The prefix can be set via GNU configure to set the install location
305 (default is /usr/local).
307 * YAZ programs client and ztest were renamed to yaz-client and
308 yaz-ztest to avoid conflicts when users install YAZ in "standard"
309 locations, such as /usr/bin,/usr/local/bin,etc.
311 * YAZ Header files were moved from include to include/yaz. YAZ Header
312 files are referred to as include <yaz/log.h> rather than <log.h>.
313 The YAZ include path (-I ..) is therefore the same as before. Programmers
314 should update their #include statements or use -Ipath/include/yaz
315 instead. The main motivation for doing this change is that YAZ header files
316 can be installed in "standard" locations /usr/include,/usr/local/include
317 without introducing conflicts, since ALL YAZ header files are stored
318 in subdirectory yaz (under /usr/include for example).
320 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
321 rather than project/workspace files. We switched because project files
322 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
325 Changed name of logging function, logf, to yaz_log, to prevent name
326 clash with some math-log functions. The YAZ header log.h defines logf
327 to yaz_log (#define) so there should be no incompatibilities by this
330 Added bend_start/bend_stop handlers for server. These handler are
331 called on start/stop of server. For windows they are called whenever
332 a service is started/stopped.
334 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
335 a fairly small ASN.1 compiler written in Tcl. The compiler is located
336 in util/yc.tcl. The auto-generated C code structures are, in a few
337 cases, incompatible with the old decoders. There are differences in the
338 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
339 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
340 The preprocessor variable ASN_COMPILED is defined when the compiled
341 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
342 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
343 wish to use the old encoders/decoders you can specify --disable-yc
346 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
347 version so that it supports both new - and old version of DB Update
349 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
350 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
351 change. The name parameter can be set to 0 in which no name is specified
352 for the construction. The macros odr_implicit and odr_explicit sets name
353 parameter to zero for the construction involved. New macros
354 odr_implicit_tag and odr_explicit_tag are similar to the others,
355 except that a name parameter is added. For programmers' that don't use
356 ODR they probably only need to change the call to z_APDU and z_External.
358 Added access control facility by interfacing the TCP wrapper library.
359 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
360 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
361 name of the daemon and enables the access control as specified in
362 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
364 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
365 den Dool <H.M.vdnDool@kub.nl>.
367 Added reference ID parameter to most functions in server API - refer
368 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
370 Changed name of ccl library to libccl.a (was ccl.a).
372 Fixed bug in decoder for Explain (Category TargetInfo).
374 Added support for GNU readline in client. Thanks to Jacob Poulsen
375 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
377 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
378 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
379 IMPLEMENTATION! This change was made to the development version before
380 the ZIG decided to retract the amendment. If any users MUST be
381 compatible with the original Update definition, PLEASE CONTACT US, and
382 we will include a separate definition corresponding to the old Update
383 ES. Note that because of the change to the ASN.1 of the
384 TaskPackageRecordStructure we cannot define a single structure that
385 will support both versions.
387 * Added const modifier to buffer parameter for some ODR/BER encoding
388 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
389 completeWAIS, odr_dumpBER.
391 Fixed bug in client.c which caused a crash when a scanResponse didn't
392 contain positionOfTerm.
394 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
395 * will cause an error in a client if a non-YAZ target sends both a
396 * list of Scan entries and non-surrogate diagnostics.
398 Retrieval module enhancements. Tag sets may be typed in the reference
399 to it. From the .abs-file the "tagset" directive takes a third optional
400 integer type for the tag set referenced. From a .tag-file the "include"
401 directive takes a third optional type as well. The old "type" directive
402 in the tag set itself is still recognized but acts as the default type
405 Backend interface change. Individual Scan terms returned from bend_scan
406 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
407 in include/backend.h.
409 Retrieval module enhancements. Multiple tag sets and attribute sets may
410 be specified in abstract syntax specs. Revised the error/warning for
411 logging messages reported by the retrieval module when reading the
414 Object Identifier system (oid_..) changed. The API is backwards
415 compatible but the oid-routines now allocates new OID's when needed.
416 Raw OID's may be specified in oid_getvalbyname.
418 YAZ now uses GNU configure to generate Makefile(s).
420 * Minor changes in some of the member names of DeleteResultSetRequest and
421 DeleteResultSetResponse. See include/proto.h.
423 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
424 and added member 'languages' in TargetInfo (which was missing).
426 Changed the way attribute sets are handled in the retrieval
427 module. These are now cached, just like the abstract syntaxes
430 Changed YAZ so that it links with compiled ASN.1.
432 Added Explain-schema definitions and mapping routines. The following
433 Explain categories have been implemented: AttributeDetails,
434 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
436 Fixed minor bug in Windows version of Server Library.
438 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
440 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
442 Added EXTERNAL: UNIverse Resource Report (non-standard).
444 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
445 ENUMERATED and SET OF.
447 * Added 'const' to some of the char pointer arguments for the
448 functions, data1_read_node, data1_getelementbytagname,
449 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
452 Fixed bug in data1_insert_taggeddata - the last_child member of
453 parent wasn't initialised.
455 * Changed data1_read_record and data1_read_node so that the supplied
456 "SGML"-buffer is read-only. In particular the resulting data1 - tree
457 doesn't refer to any parts of the "SGML"-buffer.
459 Fixed bug in server library (Windows version of statserv_remove).
461 * Changed code so that it compiles as C++. The type definition
462 of Odr_fun which is a member of Odr_arm was changed. The result is,
463 that an explicit typecast is needed for the fun pointer when
464 using Odr_arm - as in:
465 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
467 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
469 Implemented the new structured date and time definition as approved
470 by the ZIG. Added schemaId element to the specificTag in Espec-1
471 (also approved at the last ZIG). Thanks to RVDM.
473 Added some Object identifiers (RVDM).
475 Changed the Update Extended Service (RVDM).
477 Added command "refid" to client which specifies referenceId for
478 the following requests.
480 Implemented extended service handling for server. See ztest.c
481 for an example as well as backend.h. New handlers are registerd
484 * Changed interface for sort in server.
486 Added new members to statserv_options_block. It allows a server
487 to read options from another source than just the command line. Thanks
488 to Charles Woodfield.
490 * Changed definition of Z_Triple in file prt-grs.h - member boolean
491 renamed to zboolean. Some C++ compilers complained about the name.
493 Minor changes to gils.abs. Added index 's' (sort) on title
494 and date/time-last-modified.
498 Fixed bug in server library regarding inetd mode (-i). This bug
499 was introduced by release 1.4.
503 Added sort facility in client and backend server interface.
505 Fixed problem with dependencies in Makefile(s).
507 Fixed bugs for encoders/decoders of extended services and
510 Implemented sub-tree feature for schemas. Sub-trees are
511 referenced in *.abs-files. See explain.abs for an example
512 of the use of this feature.
514 Modified bib1.att; local attributes for ANY didn't include
515 ANY itself (only affects use of the retrieval module).
517 Fixed bug in plain SGML reader in function data1_read_node:
518 tags with prefix "var" was incorrectly interpreted as variants.
520 Added feature "sub-schemas" to enable references to - and definitions
521 of - group of elements.
523 * Removed member parent from type data1_element (in data1.h).
525 Implemented function odr_nullval() that returns the value of
528 * Removed member num_children from data1_node (in data1.h).
530 Made NT service interface part of the server library. The
531 function statserv_main uses the NT service when required and
532 calls the statserv_start / statserv_close routines.
534 Routine zget_SearchRequest and zget_PresentRequest fills
535 resultSetName/Id member with "default" instead of "Default".
537 Fixed memory leak in server. Request queue member wasn't freed.
539 Fixed nmem_exit so that memory is freed.
543 Revised the CCL parser utility to be thread safe.
545 Added function, oid_ent_to_oid, to replace the function
546 oid_getoidbyent, which is not thread safe.
548 * Added nmem_init and nmem_exit to initialize and release
549 NMEM resources. Function nmem_init should be called once in the
550 initial thread before NMEM/ODR is used. statserv.c and client.c
551 have been changed accordingly. The change was necessary to make
552 NMEM thread safe. The NMEM memory pool is shared amongst threads
553 in a process. Unix-based applications will still work fine without
556 Added NT Services interface for the the Z39.50 (statserv) Server.
557 Refer to the ztest.c source on the usage.
559 Windows 95/NT port using MSVC5.0. Project files are included in the
562 * Defined new 'global' handle for the retrieval (data1) system. The
563 new handled, data1_handle, describes the state of the data1 system.
564 This handle is passed as first argument to virtually all
565 data1 related routines. The functions data1_create and data1_destroy
566 creates and destroys a data1 handle respectively.
568 Added ODR encode stream member to all backend request structures
569 init, search, scan etc. This stream should be used to allocate all
570 memory used for the response when thread safe operation is needed.
572 Changed the comstack utility, cs_addstr, to be thread safe. The
573 returned hostname string returned by the function is now part the
576 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
577 function. The cs_straddr takes a COMSTACK handle as argument, so this
578 function must be used after cs_create and before bind/connect.
579 This function is thread safe.
581 Moved test server to 'ztest' directory - generic server code still
582 in 'server' directory.
584 Made prefix query (pquery.c) utility thread safe.
586 Added new function modifier YAZ_EXPORT to 'export' public DLL
587 functions when using windows (see include/yconfig.h).
589 Added definitions to the OID database (util/oid.c) (RVDM).
591 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
593 Added call to ccl_rpn_delete in client program.
595 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
596 release of RPN structure.
598 Added support for C++, headers uses extern "C" for public definitions.
599 With input from RVDM.
601 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
602 Thanks to Ronald van der Meer (RVDM).
604 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
606 Added support for private extensions to the OID database
607 (oid_setprivateoids()). Thanks to RVDM.
609 Added optional, physical ANY (key replication)
611 Fixed null-reference problem in GRS-1 output filter.
613 Proximity operator added to Prefix Query Format (PQF).
615 In test client command "base" accepts multiple databases.
617 Fixed bug in cs_close stack that caused trouble with WINSOCK.
621 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
623 Smallish bug-fixes in the new encoders/decoders (explain).
625 Bug fixed in DeleteRequest.
627 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
629 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
631 Added SOIF syntax (using private OID for now) to retrieval module and client.
633 Added Update extended service.
635 Added SearchResult-1 additional info structure.
637 Added optional CCL (ISO8777) interpreter as separate module. Available
640 --- 1.2 1996/6/10 (1st anniversary release)
642 Added Summary record syntax. Lightly tested.
644 Added OPAC record syntax. Untested.
646 Added ResourceReport service encoders/decoders. Untested.
648 Fixed bug in z_Unit - wrong tagging on unitSystem.
650 Fixed bug in the DiagRecs decoder.
652 Added options for max PDU size and session timeout to frontend-server.
654 Added documentation of query-language parsers and other supporting utilities.
656 [frontend-server] Added Attribute set to the bend_scanrequest API.
658 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
659 surrogate diagnostics were generated.
661 [retrieval] Allow multiple local values for attribute.
663 [retrieval] Allow multiple attributes per element in .abs files. index type.
665 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
669 Minor changes, mostly specific to Zebra's requirements (retrieval)
673 Repaired bug in frontend server when running multiple listening
674 endpoints in dynamic mode.
676 z_External() now won't break if a known, ASN.1 value comes encapsulated
677 in an octet-string. The value will pass through unmodified in an Odr_oct.
679 Added a bit of code to the demo client to decode & display
680 ASN.1-structured records represented in the octet-aligned branch of
681 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
683 Added z_ext_getentbyref() to the ASN module. Doc updated.
685 * Completed the SCAN definition in the ASN module. This may break SCAN
686 code based on older YAZ-versions at compile-time. The fix is easy -
689 * Added 'displayTerm' and OtherInformation to the TermInfo structure
690 under the SCAN definition. Remember to initialize this, server-people.
692 Comstack should now support the WAIS protocol in TCP/IP mode. Note
693 that this does not extend to ODR and ASN.
695 Comstack allows insertion of established socket (primarily for
696 inetd-operation of servers). Doc updated.
698 Front-end server can now start from the inetd in TCP mode. Doc
705 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
706 the rank and record number.
708 Adjustments to the frontend server.
710 Fixed diagnostic BER dumper. It ignored the file argument.
714 Various changes to retrieval module.
716 Changed the union discriminators of the protocol files from enums to
717 ints paired with #defines.
719 *Changed oident.class to oident.oclass to avoid a reserved word in C++
722 *Changed operator in the RPN structure to 'roperator', again to avoid a
725 Fixed problems in Explain decoders/encoders.
729 Memory bug in log module fixed.
733 Occasional malloc() of 0 bytes fixed in d1_espec.c.
735 Bug in Explain DatabaseInfo module fixed.
737 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
741 The shift to v1.0 signals that we now consider the *core* functionality
742 of YAZ reasonably stable (the core being more or less equivalent to
743 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
744 tested (Explain not at all - though that will happen soonish).
746 Minor changes to code to support Windows port.
748 Various minor changes after we're getting to use GRS-1 & co. more.
750 Added Espec-1 format.
752 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
753 of the protocol and it cannot be selected when encoding (maps into 'string'
754 when decoding). Needed to talk to some servers.
756 Demo client can request simple element set names.
758 Added Diagnostic Format encoders/decoders.
760 Added simple Close handling to frontend server (no hooks for resource
761 reporting yet), and demonstration client.
763 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
767 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
768 handled incorrectly when records were requested in the searchResponse. This
769 will only affect you if you use the frontend-server.
771 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
772 Test-client will ask for and print GRS1. Ztest will return dummy records
775 Added Explain encoders/decoders to the service-level API. Untested.
777 Added Extended Services: Item Order encoders and decoders to the Service-
778 level API. Untested. We could use a recent copy of the pertinent bits
779 of the ILL protocol to add those bits.
781 Added diagnostic format 1 encoders/decoders to the service-level API.
784 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
785 odr_cons.c, which causes a more correct output.
787 Fixed handling of searchRequest in frontend server. NextResultSetPosition
788 was always set to 0 when no records were requested in the searchRequest.
790 * Added better external-handling. This shouldn't harm old code that
791 *encodes* externals. It can break code that looks for a
792 'single-ASN1-type' representation, since those types that are known
793 are now decoded immediately. Look at the SUTRS sample code in
794 seshigh.c and client.c. Documentation updated.
796 Handling of structured records in bend_fetchresponse. Length -1 marks
797 structured record, type is deduced from format field.
800 Fairly quick maintenance release to add SUTRS support.
802 Fixed handling of SUTRS records in the demonstration client.
804 * Added format field to the bend_fetchrequest and bend_fetchresponce
805 structures of the backend API (frontend server). When the record is
806 returned, the value of the format field is mapped to an OID. The
807 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
808 of the record. The special value VAL_NONE in the bend_request means
809 that no specific format was requested by the client. Documentation
810 updated accordingly. Test server (ztest) will return a fixed dummy
811 SUTRS record if your client requests SUTRS.
813 Documentation updated accordingly.
815 You can now set external libraries and RANLIB support in the top-level
819 First public release.
