1 Possible compatibility problems with earlier versions marked with '*'.
5 SGML reader parses comments and makes them part of the data1 tree.
7 Added several type casts so that YAZ compiles as C++ code.
9 ZOOM didn't handle PDU encoding failures properly.
11 Added more Bib-1 diagnostics (approved extensions).
13 Better check for iconv.
15 More portable use of accept, getpeername. Check for socklen_t. Use
16 int/size_t if socklen_t is not defined.
20 PQF parser rejects bad queries - including those with extra
21 characters in them. PQF parser used to silently ignore that.
22 Cleaner API for PQF added, which allows you to get detailed
23 error information for bad queries (see yaz/pquery.h).
25 Fixed bug in ZOOM_record_get for type "database".
27 Implemented mini iconv library supporting conversions between
28 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
30 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
34 Fixed ZOOM C record cache so that preferredRecordSyntax and
35 elementSetName is used to check for already fetched records.
39 Added three members in bend_initrequest structure to facilitate
40 character set negotiation.
42 Fixed a bug in frontend server that could cause indefinite
43 loops under rare conditions.
45 Revised character set utilities (charneg.h) so that encoding
46 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
48 For PQF, directive @term <type> sets term type for Scan/Search.
49 Here <type> is general, string, numeric, null. The term type
50 is inherited - just like @attr.
52 New call odr_set_charset that sets character set conversion for
53 international-strings on a ODR stream. Prototype is:
54 int odr_set_charset(ODR o, const char *to, const char *from);
55 The InternationalString is still represented as C string in YAZ
56 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
57 won't). On the protocol level, you can use any encoding.
59 Support for UNIX sockets in ZOOM.
61 Solaris recv sometimes returns errno == ENOENT. It is treated as
62 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
64 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
65 both client and server. Code by Morten Bøgeskov.
69 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
70 that they can be used directly from Visual Basic. You must recompile
71 your windows APP if you're using ZOOM.
73 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
74 Commands "lang" and "charset" sets language and character set respectively.
75 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
76 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
78 Attributes from multiple CCL fields may be OR'ed rather than merged
79 using directive "@field or". Fields are still merged by default -
80 equivalent to "@field merge".
82 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
85 Fixed bug in zget for parameter ExtendedServicesResponse.
91 Added PQF feature: '@attr type=value' may be written as '@type=value'.
93 Client displays USR.1:SearchResult-1 (hits per term).
95 Additional Search Info for search in Generic Frontend Server.
97 Fixed CCL parsing of "field=s".
99 WIN32 installer - using the excellent NSIS software from nullsoft.
101 Fixed CCL parsing of "field = - <number>".
103 Added function yaz_marc_decode that decodes MARC for line mode
104 display or XML (similar to that used by JZKit).
106 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
107 Z39.50. But ISO/ILL was, however.
109 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
110 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

113 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
117 New YAZ client features: Command completion and new commands:
118 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
119 Code provided by Jacob Poulsen.
121 New call oid_trav, that visits all registered OIDs via callback.
123 Function ZOOM_record_get now returns const char pointer rather than
124 void pointer. It saves a lot of type casts.
126 For YAZ client, command "auth" now allows you to set authentication
127 in IdPass style. It is enabled when three tokens are given - order
128 is user, group and password.
130 Fix memory leaks in MARC record handling for ZOOM.
132 New option for YAZ client, -k <kilobytes> that sets
133 maximum record size. Similar to -k option for generic frontend
134 server and yaz-ztest.
136 More fixes for scan. Non-zero stepSize handled. OID's fixes.
138 Prefix query parser reports "fail" when bad attribute set is given.
140 Fix in MARC decoder. Proximity logging. Fix for attribute set
141 in scan handler for server. Patches by Shigeru Ishida.
143 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
146 Configure option --with-openssl=<dir> now works when a directory is
147 specified. Patch provided by Morten Bøgeskov.
149 New option for YAZ client, -u <auth>, that sets authentication.
151 ZOOM fix: error information was sometimes "missing", since error
152 was cleared/reset too when it shouldn't.
154 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
158 Scan for ZOOM API. New object ZOOM_scanset. New functions
159 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
160 ZOOM_scanset_destroy.
162 New ZOOM function, ZOOM_connection_last_event, that returns type
163 of last event (such as "receive data", "send data", "apdu received",
166 New ZOOM option, schema, that specifies shema OID for retrieval.
168 New CCL feature. Qualifiers can be aliases for one or more
169 other qualifiers (if more than one is given, OR is used).
171 ZOOM uses named result sets if target supports it.
173 Two new YAZ client commands: . (dot, which sources a script of YAZ
174 client commands), and ! (to execute shell command.). Implemented
177 Working on Debian packages.
181 YAZ client enables named result sets only if target supports it.
183 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
185 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
186 with key="host" to get same result.
188 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
189 Function Z3950_resultset_record(s) returns references to records
190 "owned" by resultset. To become owner use Z3950_record_clone.
192 Function z_ext_record handles Extended Services. Thanks to
197 CCL Parser fix: ignore token comma when dealing with and-lists.
199 Documentation updates for COMSTACK.
201 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
202 Changed prototype Z3950_records. For some functions, int parameters
203 were changed to size_t.
205 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
208 New MARC decode/display function, marc_display_exl, which properly rejects
209 non-ISO2709 records. YAZ client uses it.
213 Fix bug: local attribute set wasn't set correctly in PQF strings.
217 * Old Z39.50 codecs no longer supported.
219 Added ZOOM C binding. See http://zoom.z3950.org/
221 Renamed states for COMSTACKs to avoid confusion with events.
223 Implemented cs_look and proper cs_rcvconnect.
225 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
227 Configure detects POSIX threads on OpenBSD.
229 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
230 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
232 When error is returned from present handler, non-surrogate diagnostic
233 is returned in present response (and fetch handler is no longer called).
235 * Minor adjustments to pquery parser (PQF). Token characters may be
236 escaped by using backslash (C-style).
238 PQF parser allows string attribute values to be specified. For @attr,
239 non-numeric characters after the equal-sign are treated as strings
240 (e.g. @attr 9=title).
242 CCL trunction character may be defined (@truncation in file)
244 * function zget_ExtendedServicesRequest sets waitAction to
245 waitIfPossible (was wait).
247 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
250 CCL operator names may be set in field definition files (CCL_bibset).
251 See ccl/bib1 for an example.
253 Fixes in ASN.1 compiler for C++ compatibility.
255 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
256 and "op_or" to avoid conflict with C++.
258 Fixed problem with GNU readline detection on Redhat 7.0.
260 Added step-size for Scan backend handler.
262 Fixed bug that made the frontend server crash when no attribute
263 set was specified for scan.
265 Front-end server automatically switches to original working directory
266 when installed as an NT service. Previously -w had to be specified to
269 Added extended attributes for retrieval module (data1), so that data1
270 records carry d1_readXML/SGML attributes. d1_read also supports
271 null-data rules ( <tag/>)
273 On UNIX when POSIX threads are available, a separate library libyazthread
274 is created. Programmers should link with that library and the yaz library
275 when using threads. The reason for the split was that some applications
276 on Linux, such as Apache, doesn't work well when using shared objects that
279 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
280 (or any frontend server) in SSL mode by specifying ssl: followed by
281 address. Only tested on UNIX.
283 Added feature for CCL module. Virtual structure s=al or s=ol generates
284 and-list and or-list respectively instead of phrase search.
288 * Added prefix "yaz_" for the functions log_init.., log_file.. and
289 log_mask_str. This was done to avoid name conflicts with other libraries
290 (such as other PHP extensions).
292 Added raw OID member for preferred record syntax (request_format_raw)
293 and returned record syntax (output_format_raw) for backend fetch method.
295 Config file yaz-config now accepts options so that it returns specific
296 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
298 Shared library support for UNIX using GNU libtool.
300 * Modified backend interface. Request/Response struct's replaced by
301 one read/write C struct. For example bend_fetchrequest and
302 bend_fetchresult have been replaced by single bend_fetch_rr struct.
303 Every handler - even search has to be registered in bend_init
304 handler. This means that the YAZ library no longer refers to
305 external functions and it makes it possible to make the whole
306 thing a single DLL/SO.
308 Added Segment handler for backend server.
310 Added Zmbol/Zebra administrative functions to YAZ client.
312 Threaded frontend server on UNIX (when POSIX Threads are available).
313 Starting the server with option -T enables multi-threading.
317 Added configure option --enable-comp/disable-comp to control use
318 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
319 located in sub directory asn.
321 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
322 in ${exec_prefix}/bin along with the other programs yaz-client and
325 GNU automake used to maintain makefiles.
329 Changed retrieval module so that we can load records with no abstract
330 syntax defined. Tagpaths in these records are fully composed of string
333 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
337 On UNIX, the generated makefile now supports a proper 'make install'.
338 The prefix can be set via GNU configure to set the install location
339 (default is /usr/local).
341 * YAZ programs client and ztest were renamed to yaz-client and
342 yaz-ztest to avoid conflicts when users install YAZ in "standard"
343 locations, such as /usr/bin,/usr/local/bin,etc.
345 * YAZ Header files were moved from include to include/yaz. YAZ Header
346 files are referred to as include <yaz/log.h> rather than <log.h>.
347 The YAZ include path (-I ..) is therefore the same as before. Programmers
348 should update their #include statements or use -Ipath/include/yaz
349 instead. The main motivation for doing this change is that YAZ header files
350 can be installed in "standard" locations /usr/include,/usr/local/include
351 without introducing conflicts, since ALL YAZ header files are stored
352 in subdirectory yaz (under /usr/include for example).
354 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
355 rather than project/workspace files. We switched because project files
356 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
359 Changed name of logging function, logf, to yaz_log, to prevent name
360 clash with some math-log functions. The YAZ header log.h defines logf
361 to yaz_log (#define) so there should be no incompatibilities by this
364 Added bend_start/bend_stop handlers for server. These handler are
365 called on start/stop of server. For windows they are called whenever
366 a service is started/stopped.
368 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
369 a fairly small ASN.1 compiler written in Tcl. The compiler is located
370 in util/yc.tcl. The auto-generated C code structures are, in a few
371 cases, incompatible with the old decoders. There are differences in the
372 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
373 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
374 The preprocessor variable ASN_COMPILED is defined when the compiled
375 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
376 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
377 wish to use the old encoders/decoders you can specify --disable-yc
380 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
381 version so that it supports both new - and old version of DB Update
383 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
384 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
385 change. The name parameter can be set to 0 in which no name is specified
386 for the construction. The macros odr_implicit and odr_explicit sets name
387 parameter to zero for the construction involved. New macros
388 odr_implicit_tag and odr_explicit_tag are similar to the others,
389 except that a name parameter is added. For programmers' that don't use
390 ODR they probably only need to change the call to z_APDU and z_External.
392 Added access control facility by interfacing the TCP wrapper library.
393 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
394 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
395 name of the daemon and enables the access control as specified in
396 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
398 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
399 den Dool <H.M.vdnDool@kub.nl>.
401 Added reference ID parameter to most functions in server API - refer
402 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
404 Changed name of ccl library to libccl.a (was ccl.a).
406 Fixed bug in decoder for Explain (Category TargetInfo).
408 Added support for GNU readline in client. Thanks to Jacob Poulsen
409 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
411 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
412 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
413 IMPLEMENTATION! This change was made to the development version before
414 the ZIG decided to retract the amendment. If any users MUST be
415 compatible with the original Update definition, PLEASE CONTACT US, and
416 we will include a separate definition corresponding to the old Update
417 ES. Note that because of the change to the ASN.1 of the
418 TaskPackageRecordStructure we cannot define a single structure that
419 will support both versions.
421 * Added const modifier to buffer parameter for some ODR/BER encoding
422 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
423 completeWAIS, odr_dumpBER.
425 Fixed bug in client.c which caused a crash when a scanResponse didn't
426 contain positionOfTerm.
428 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
429 * will cause an error in a client if a non-YAZ target sends both a
430 * list of Scan entries and non-surrogate diagnostics.
432 Retrieval module enhancements. Tag sets may be typed in the reference
433 to it. From the .abs-file the "tagset" directive takes a third optional
434 integer type for the tag set referenced. From a .tag-file the "include"
435 directive takes a third optional type as well. The old "type" directive
436 in the tag set itself is still recognized but acts as the default type
439 Backend interface change. Individual Scan terms returned from bend_scan
440 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
441 in include/backend.h.
443 Retrieval module enhancements. Multiple tag sets and attribute sets may
444 be specified in abstract syntax specs. Revised the error/warning for
445 logging messages reported by the retrieval module when reading the
448 Object Identifier system (oid_..) changed. The API is backwards
449 compatible but the oid-routines now allocates new OID's when needed.
450 Raw OID's may be specified in oid_getvalbyname.
452 YAZ now uses GNU configure to generate Makefile(s).
454 * Minor changes in some of the member names of DeleteResultSetRequest and
455 DeleteResultSetResponse. See include/proto.h.
457 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
458 and added member 'languages' in TargetInfo (which was missing).
460 Changed the way attribute sets are handled in the retrieval
461 module. These are now cached, just like the abstract syntaxes
464 Changed YAZ so that it links with compiled ASN.1.
466 Added Explain-schema definitions and mapping routines. The following
467 Explain categories have been implemented: AttributeDetails,
468 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
470 Fixed minor bug in Windows version of Server Library.
472 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
474 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
476 Added EXTERNAL: UNIverse Resource Report (non-standard).
478 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
479 ENUMERATED and SET OF.
481 * Added 'const' to some of the char pointer arguments for the
482 functions, data1_read_node, data1_getelementbytagname,
483 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
486 Fixed bug in data1_insert_taggeddata - the last_child member of
487 parent wasn't initialised.
489 * Changed data1_read_record and data1_read_node so that the supplied
490 "SGML"-buffer is read-only. In particular the resulting data1 - tree
491 doesn't refer to any parts of the "SGML"-buffer.
493 Fixed bug in server library (Windows version of statserv_remove).
495 * Changed code so that it compiles as C++. The type definition
496 of Odr_fun which is a member of Odr_arm was changed. The result is,
497 that an explicit typecast is needed for the fun pointer when
498 using Odr_arm - as in:
499 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
501 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
503 Implemented the new structured date and time definition as approved
504 by the ZIG. Added schemaId element to the specificTag in Espec-1
505 (also approved at the last ZIG). Thanks to RVDM.
507 Added some Object identifiers (RVDM).
509 Changed the Update Extended Service (RVDM).
511 Added command "refid" to client which specifies referenceId for
512 the following requests.
514 Implemented extended service handling for server. See ztest.c
515 for an example as well as backend.h. New handlers are registerd
518 * Changed interface for sort in server.
520 Added new members to statserv_options_block. It allows a server
521 to read options from another source than just the command line. Thanks
522 to Charles Woodfield.
524 * Changed definition of Z_Triple in file prt-grs.h - member boolean
525 renamed to zboolean. Some C++ compilers complained about the name.
527 Minor changes to gils.abs. Added index 's' (sort) on title
528 and date/time-last-modified.
532 Fixed bug in server library regarding inetd mode (-i). This bug
533 was introduced by release 1.4.
537 Added sort facility in client and backend server interface.
539 Fixed problem with dependencies in Makefile(s).
541 Fixed bugs for encoders/decoders of extended services and
544 Implemented sub-tree feature for schemas. Sub-trees are
545 referenced in *.abs-files. See explain.abs for an example
546 of the use of this feature.
548 Modified bib1.att; local attributes for ANY didn't include
549 ANY itself (only affects use of the retrieval module).
551 Fixed bug in plain SGML reader in function data1_read_node:
552 tags with prefix "var" was incorrectly interpreted as variants.
554 Added feature "sub-schemas" to enable references to - and definitions
555 of - group of elements.
557 * Removed member parent from type data1_element (in data1.h).
559 Implemented function odr_nullval() that returns the value of
562 * Removed member num_children from data1_node (in data1.h).
564 Made NT service interface part of the server library. The
565 function statserv_main uses the NT service when required and
566 calls the statserv_start / statserv_close routines.
568 Routine zget_SearchRequest and zget_PresentRequest fills
569 resultSetName/Id member with "default" instead of "Default".
571 Fixed memory leak in server. Request queue member wasn't freed.
573 Fixed nmem_exit so that memory is freed.
577 Revised the CCL parser utility to be thread safe.
579 Added function, oid_ent_to_oid, to replace the function
580 oid_getoidbyent, which is not thread safe.
582 * Added nmem_init and nmem_exit to initialize and release
583 NMEM resources. Function nmem_init should be called once in the
584 initial thread before NMEM/ODR is used. statserv.c and client.c
585 have been changed accordingly. The change was necessary to make
586 NMEM thread safe. The NMEM memory pool is shared amongst threads
587 in a process. Unix-based applications will still work fine without
590 Added NT Services interface for the the Z39.50 (statserv) Server.
591 Refer to the ztest.c source on the usage.
593 Windows 95/NT port using MSVC5.0. Project files are included in the
596 * Defined new 'global' handle for the retrieval (data1) system. The
597 new handled, data1_handle, describes the state of the data1 system.
598 This handle is passed as first argument to virtually all
599 data1 related routines. The functions data1_create and data1_destroy
600 creates and destroys a data1 handle respectively.
602 Added ODR encode stream member to all backend request structures
603 init, search, scan etc. This stream should be used to allocate all
604 memory used for the response when thread safe operation is needed.
606 Changed the comstack utility, cs_addstr, to be thread safe. The
607 returned hostname string returned by the function is now part the
610 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
611 function. The cs_straddr takes a COMSTACK handle as argument, so this
612 function must be used after cs_create and before bind/connect.
613 This function is thread safe.
615 Moved test server to 'ztest' directory - generic server code still
616 in 'server' directory.
618 Made prefix query (pquery.c) utility thread safe.
620 Added new function modifier YAZ_EXPORT to 'export' public DLL
621 functions when using windows (see include/yconfig.h).
623 Added definitions to the OID database (util/oid.c) (RVDM).
625 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
627 Added call to ccl_rpn_delete in client program.
629 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
630 release of RPN structure.
632 Added support for C++, headers uses extern "C" for public definitions.
633 With input from RVDM.
635 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
636 Thanks to Ronald van der Meer (RVDM).
638 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
640 Added support for private extensions to the OID database
641 (oid_setprivateoids()). Thanks to RVDM.
643 Added optional, physical ANY (key replication)
645 Fixed null-reference problem in GRS-1 output filter.
647 Proximity operator added to Prefix Query Format (PQF).
649 In test client command "base" accepts multiple databases.
651 Fixed bug in cs_close stack that caused trouble with WINSOCK.
655 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
657 Smallish bug-fixes in the new encoders/decoders (explain).
659 Bug fixed in DeleteRequest.
661 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
663 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
665 Added SOIF syntax (using private OID for now) to retrieval module and client.
667 Added Update extended service.
669 Added SearchResult-1 additional info structure.
671 Added optional CCL (ISO8777) interpreter as separate module. Available
674 --- 1.2 1996/6/10 (1st anniversary release)
676 Added Summary record syntax. Lightly tested.
678 Added OPAC record syntax. Untested.
680 Added ResourceReport service encoders/decoders. Untested.
682 Fixed bug in z_Unit - wrong tagging on unitSystem.
684 Fixed bug in the DiagRecs decoder.
686 Added options for max PDU size and session timeout to frontend-server.
688 Added documentation of query-language parsers and other supporting utilities.
690 [frontend-server] Added Attribute set to the bend_scanrequest API.
692 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
693 surrogate diagnostics were generated.
695 [retrieval] Allow multiple local values for attribute.
697 [retrieval] Allow multiple attributes per element in .abs files. index type.
699 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
703 Minor changes, mostly specific to Zebra's requirements (retrieval)
707 Repaired bug in frontend server when running multiple listening
708 endpoints in dynamic mode.
710 z_External() now won't break if a known, ASN.1 value comes encapsulated
711 in an octet-string. The value will pass through unmodified in an Odr_oct.
713 Added a bit of code to the demo client to decode & display
714 ASN.1-structured records represented in the octet-aligned branch of
715 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
717 Added z_ext_getentbyref() to the ASN module. Doc updated.
719 * Completed the SCAN definition in the ASN module. This may break SCAN
720 code based on older YAZ-versions at compile-time. The fix is easy -
723 * Added 'displayTerm' and OtherInformation to the TermInfo structure
724 under the SCAN definition. Remember to initialize this, server-people.
726 Comstack should now support the WAIS protocol in TCP/IP mode. Note
727 that this does not extend to ODR and ASN.
729 Comstack allows insertion of established socket (primarily for
730 inetd-operation of servers). Doc updated.
732 Front-end server can now start from the inetd in TCP mode. Doc
739 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
740 the rank and record number.
742 Adjustments to the frontend server.
744 Fixed diagnostic BER dumper. It ignored the file argument.
748 Various changes to retrieval module.
750 Changed the union discriminators of the protocol files from enums to
751 ints paired with #defines.
753 *Changed oident.class to oident.oclass to avoid a reserved word in C++
756 *Changed operator in the RPN structure to 'roperator', again to avoid a
759 Fixed problems in Explain decoders/encoders.
763 Memory bug in log module fixed.
767 Occasional malloc() of 0 bytes fixed in d1_espec.c.
769 Bug in Explain DatabaseInfo module fixed.
771 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
775 The shift to v1.0 signals that we now consider the *core* functionality
776 of YAZ reasonably stable (the core being more or less equivalent to
777 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
778 tested (Explain not at all - though that will happen soonish).
780 Minor changes to code to support Windows port.
782 Various minor changes after we're getting to use GRS-1 & co. more.
784 Added Espec-1 format.
786 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
787 of the protocol and it cannot be selected when encoding (maps into 'string'
788 when decoding). Needed to talk to some servers.
790 Demo client can request simple element set names.
792 Added Diagnostic Format encoders/decoders.
794 Added simple Close handling to frontend server (no hooks for resource
795 reporting yet), and demonstration client.
797 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
801 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
802 handled incorrectly when records were requested in the searchResponse. This
803 will only affect you if you use the frontend-server.
805 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
806 Test-client will ask for and print GRS1. Ztest will return dummy records
809 Added Explain encoders/decoders to the service-level API. Untested.
811 Added Extended Services: Item Order encoders and decoders to the Service-
812 level API. Untested. We could use a recent copy of the pertinent bits
813 of the ILL protocol to add those bits.
815 Added diagnostic format 1 encoders/decoders to the service-level API.
818 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
819 odr_cons.c, which causes a more correct output.
821 Fixed handling of searchRequest in frontend server. NextResultSetPosition
822 was always set to 0 when no records were requested in the searchRequest.
824 * Added better external-handling. This shouldn't harm old code that
825 *encodes* externals. It can break code that looks for a
826 'single-ASN1-type' representation, since those types that are known
827 are now decoded immediately. Look at the SUTRS sample code in
828 seshigh.c and client.c. Documentation updated.
830 Handling of structured records in bend_fetchresponse. Length -1 marks
831 structured record, type is deduced from format field.
834 Fairly quick maintenance release to add SUTRS support.
836 Fixed handling of SUTRS records in the demonstration client.
838 * Added format field to the bend_fetchrequest and bend_fetchresponce
839 structures of the backend API (frontend server). When the record is
840 returned, the value of the format field is mapped to an OID. The
841 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
842 of the record. The special value VAL_NONE in the bend_request means
843 that no specific format was requested by the client. Documentation
844 updated accordingly. Test server (ztest) will return a fixed dummy
845 SUTRS record if your client requests SUTRS.
847 Documentation updated accordingly.
849 You can now set external libraries and RANLIB support in the top-level
853 First public release.
