1 Possible compatibility problems with earlier versions marked with '*'.
5 New MARC decode API. All new functions operate on a yaz_marc_t
6 handle. The most important new functions are: yaz_marc_create,
7 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
8 decode and destroy respectively. Decoder can produce formats
9 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
10 include/yaz/marcdisp.h.
12 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
13 to UTF-8, UCS-32, wchar_t or Latin-1.
15 * Prototypes for yaz_iconv_-functions moved to separate header
16 include/yaz/yaz-iconv.h.
18 Make a few private functions 'static' in unix.c. This prevents
19 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
21 For ZOOM connection, the options targetImplementation{Id,Name,Version}
22 are set when Init Response is received.
24 New function ZOOM_connection_error_x similar to ZOOM_connection_error
25 but returns diagnostic set as well.
27 New function yaz_strerror which is a portable wrapper for
28 strerror/strerror_r/GetLastMessage.
30 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
31 is returned for MARC. If type is "oai", then OAI MARC is returned.
33 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
38 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
40 Fix bad race conditions on SIGTERM and terminate gracefully in
43 Move retrieval (data1) module to Zebra since nobody seems to be
46 Add GRS-1 render for ZOOM using same format as yaz-client.
50 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
52 Fix broken ESpec handling in data1 module.
54 SGML reader parses comments and makes them part of the data1 tree.
56 Added several type casts so that YAZ compiles as C++ code.
58 ZOOM didn't handle PDU encoding failures properly.
60 Added more Bib-1 diagnostics (approved extensions).
62 GNU configure: better check for iconv.
64 More portable use of accept, getpeername. Check for socklen_t. Use
65 int/size_t if socklen_t is not defined.
69 PQF parser rejects bad queries - including those with extra
70 characters in them. PQF parser used to silently ignore that.
71 Cleaner API for PQF added, which allows you to get detailed
72 error information for bad queries (see yaz/pquery.h).
74 Fixed bug in ZOOM_record_get for type "database".
76 Implemented mini iconv library supporting conversions between
77 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
79 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
83 Fixed ZOOM C record cache so that preferredRecordSyntax and
84 elementSetName is used to check for already fetched records.
88 Added three members in bend_initrequest structure to facilitate
89 character set negotiation.
91 Fixed a bug in frontend server that could cause indefinite
92 loops under rare conditions.
94 Revised character set utilities (charneg.h) so that encoding
95 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
97 For PQF, directive @term <type> sets term type for Scan/Search.
98 Here <type> is general, string, numeric, null. The term type
99 is inherited - just like @attr.
101 New call odr_set_charset that sets character set conversion for
102 international-strings on a ODR stream. Prototype is:
103 int odr_set_charset(ODR o, const char *to, const char *from);
104 The InternationalString is still represented as C string in YAZ
105 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
106 won't). On the protocol level, you can use any encoding.
108 Support for UNIX sockets in ZOOM.
110 Solaris recv sometimes returns errno == ENOENT. It is treated as
111 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
113 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
114 both client and server. Code by Morten Bøgeskov.
118 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
119 that they can be used directly from Visual Basic. You must recompile
120 your windows APP if you're using ZOOM.
122 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
123 Commands "lang" and "charset" sets language and character set respectively.
124 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
125 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
127 Attributes from multiple CCL fields may be OR'ed rather than merged
128 using directive "@field or". Fields are still merged by default -
129 equivalent to "@field merge".
131 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
134 Fixed bug in zget for parameter ExtendedServicesResponse.
140 Added PQF feature: '@attr type=value' may be written as '@type=value'.
142 Client displays USR.1:SearchResult-1 (hits per term).
144 Additional Search Info for search in Generic Frontend Server.
146 Fixed CCL parsing of "field=s".
148 WIN32 installer - using the excellent NSIS software from nullsoft.
150 Fixed CCL parsing of "field = - <number>".
152 Added function yaz_marc_decode that decodes MARC for line mode
153 display or XML (similar to that used by JZKit).
155 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
156 Z39.50. But ISO/ILL was, however.
158 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
159 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

162 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
166 New YAZ client features: Command completion and new commands:
167 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
168 Code provided by Jacob Poulsen.
170 New call oid_trav, that visits all registered OIDs via callback.
172 Function ZOOM_record_get now returns const char pointer rather than
173 void pointer. It saves a lot of type casts.
175 For YAZ client, command "auth" now allows you to set authentication
176 in IdPass style. It is enabled when three tokens are given - order
177 is user, group and password.
179 Fix memory leaks in MARC record handling for ZOOM.
181 New option for YAZ client, -k <kilobytes> that sets
182 maximum record size. Similar to -k option for generic frontend
183 server and yaz-ztest.
185 More fixes for scan. Non-zero stepSize handled. OID's fixes.
187 Prefix query parser reports "fail" when bad attribute set is given.
189 Fix in MARC decoder. Proximity logging. Fix for attribute set
190 in scan handler for server. Patches by Shigeru Ishida.
192 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
195 Configure option --with-openssl=<dir> now works when a directory is
196 specified. Patch provided by Morten Bøgeskov.
198 New option for YAZ client, -u <auth>, that sets authentication.
200 ZOOM fix: error information was sometimes "missing", since error
201 was cleared/reset too when it shouldn't.
203 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
207 Scan for ZOOM API. New object ZOOM_scanset. New functions
208 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
209 ZOOM_scanset_destroy.
211 New ZOOM function, ZOOM_connection_last_event, that returns type
212 of last event (such as "receive data", "send data", "apdu received",
215 New ZOOM option, schema, that specifies shema OID for retrieval.
217 New CCL feature. Qualifiers can be aliases for one or more
218 other qualifiers (if more than one is given, OR is used).
220 ZOOM uses named result sets if target supports it.
222 Two new YAZ client commands: . (dot, which sources a script of YAZ
223 client commands), and ! (to execute shell command.). Implemented
226 Working on Debian packages.
230 YAZ client enables named result sets only if target supports it.
232 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
234 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
235 with key="host" to get same result.
237 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
238 Function Z3950_resultset_record(s) returns references to records
239 "owned" by resultset. To become owner use Z3950_record_clone.
241 Function z_ext_record handles Extended Services. Thanks to
246 CCL Parser fix: ignore token comma when dealing with and-lists.
248 Documentation updates for COMSTACK.
250 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
251 Changed prototype Z3950_records. For some functions, int parameters
252 were changed to size_t.
254 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
257 New MARC decode/display function, marc_display_exl, which properly rejects
258 non-ISO2709 records. YAZ client uses it.
262 Fix bug: local attribute set wasn't set correctly in PQF strings.
266 * Old Z39.50 codecs no longer supported.
268 Added ZOOM C binding. See http://zoom.z3950.org/
270 Renamed states for COMSTACKs to avoid confusion with events.
272 Implemented cs_look and proper cs_rcvconnect.
274 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
276 Configure detects POSIX threads on OpenBSD.
278 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
279 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
281 When error is returned from present handler, non-surrogate diagnostic
282 is returned in present response (and fetch handler is no longer called).
284 * Minor adjustments to pquery parser (PQF). Token characters may be
285 escaped by using backslash (C-style).
287 PQF parser allows string attribute values to be specified. For @attr,
288 non-numeric characters after the equal-sign are treated as strings
289 (e.g. @attr 9=title).
291 CCL trunction character may be defined (@truncation in file)
293 * function zget_ExtendedServicesRequest sets waitAction to
294 waitIfPossible (was wait).
296 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
299 CCL operator names may be set in field definition files (CCL_bibset).
300 See ccl/bib1 for an example.
302 Fixes in ASN.1 compiler for C++ compatibility.
304 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
305 and "op_or" to avoid conflict with C++.
307 Fixed problem with GNU readline detection on Redhat 7.0.
309 Added step-size for Scan backend handler.
311 Fixed bug that made the frontend server crash when no attribute
312 set was specified for scan.
314 Front-end server automatically switches to original working directory
315 when installed as an NT service. Previously -w had to be specified to
318 Added extended attributes for retrieval module (data1), so that data1
319 records carry d1_readXML/SGML attributes. d1_read also supports
320 null-data rules ( <tag/>)
322 On UNIX when POSIX threads are available, a separate library libyazthread
323 is created. Programmers should link with that library and the yaz library
324 when using threads. The reason for the split was that some applications
325 on Linux, such as Apache, doesn't work well when using shared objects that
328 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
329 (or any frontend server) in SSL mode by specifying ssl: followed by
330 address. Only tested on UNIX.
332 Added feature for CCL module. Virtual structure s=al or s=ol generates
333 and-list and or-list respectively instead of phrase search.
337 * Added prefix "yaz_" for the functions log_init.., log_file.. and
338 log_mask_str. This was done to avoid name conflicts with other libraries
339 (such as other PHP extensions).
341 Added raw OID member for preferred record syntax (request_format_raw)
342 and returned record syntax (output_format_raw) for backend fetch method.
344 Config file yaz-config now accepts options so that it returns specific
345 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
347 Shared library support for UNIX using GNU libtool.
349 * Modified backend interface. Request/Response struct's replaced by
350 one read/write C struct. For example bend_fetchrequest and
351 bend_fetchresult have been replaced by single bend_fetch_rr struct.
352 Every handler - even search has to be registered in bend_init
353 handler. This means that the YAZ library no longer refers to
354 external functions and it makes it possible to make the whole
355 thing a single DLL/SO.
357 Added Segment handler for backend server.
359 Added Zmbol/Zebra administrative functions to YAZ client.
361 Threaded frontend server on UNIX (when POSIX Threads are available).
362 Starting the server with option -T enables multi-threading.
366 Added configure option --enable-comp/disable-comp to control use
367 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
368 located in sub directory asn.
370 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
371 in ${exec_prefix}/bin along with the other programs yaz-client and
374 GNU automake used to maintain makefiles.
378 Changed retrieval module so that we can load records with no abstract
379 syntax defined. Tagpaths in these records are fully composed of string
382 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
386 On UNIX, the generated makefile now supports a proper 'make install'.
387 The prefix can be set via GNU configure to set the install location
388 (default is /usr/local).
390 * YAZ programs client and ztest were renamed to yaz-client and
391 yaz-ztest to avoid conflicts when users install YAZ in "standard"
392 locations, such as /usr/bin,/usr/local/bin,etc.
394 * YAZ Header files were moved from include to include/yaz. YAZ Header
395 files are referred to as include <yaz/log.h> rather than <log.h>.
396 The YAZ include path (-I ..) is therefore the same as before. Programmers
397 should update their #include statements or use -Ipath/include/yaz
398 instead. The main motivation for doing this change is that YAZ header files
399 can be installed in "standard" locations /usr/include,/usr/local/include
400 without introducing conflicts, since ALL YAZ header files are stored
401 in subdirectory yaz (under /usr/include for example).
403 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
404 rather than project/workspace files. We switched because project files
405 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
408 Changed name of logging function, logf, to yaz_log, to prevent name
409 clash with some math-log functions. The YAZ header log.h defines logf
410 to yaz_log (#define) so there should be no incompatibilities by this
413 Added bend_start/bend_stop handlers for server. These handler are
414 called on start/stop of server. For windows they are called whenever
415 a service is started/stopped.
417 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
418 a fairly small ASN.1 compiler written in Tcl. The compiler is located
419 in util/yc.tcl. The auto-generated C code structures are, in a few
420 cases, incompatible with the old decoders. There are differences in the
421 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
422 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
423 The preprocessor variable ASN_COMPILED is defined when the compiled
424 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
425 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
426 wish to use the old encoders/decoders you can specify --disable-yc
429 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
430 version so that it supports both new - and old version of DB Update
432 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
433 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
434 change. The name parameter can be set to 0 in which no name is specified
435 for the construction. The macros odr_implicit and odr_explicit sets name
436 parameter to zero for the construction involved. New macros
437 odr_implicit_tag and odr_explicit_tag are similar to the others,
438 except that a name parameter is added. For programmers' that don't use
439 ODR they probably only need to change the call to z_APDU and z_External.
441 Added access control facility by interfacing the TCP wrapper library.
442 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
443 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
444 name of the daemon and enables the access control as specified in
445 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
447 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
448 den Dool <H.M.vdnDool@kub.nl>.
450 Added reference ID parameter to most functions in server API - refer
451 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
453 Changed name of ccl library to libccl.a (was ccl.a).
455 Fixed bug in decoder for Explain (Category TargetInfo).
457 Added support for GNU readline in client. Thanks to Jacob Poulsen
458 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
460 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
461 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
462 IMPLEMENTATION! This change was made to the development version before
463 the ZIG decided to retract the amendment. If any users MUST be
464 compatible with the original Update definition, PLEASE CONTACT US, and
465 we will include a separate definition corresponding to the old Update
466 ES. Note that because of the change to the ASN.1 of the
467 TaskPackageRecordStructure we cannot define a single structure that
468 will support both versions.
470 * Added const modifier to buffer parameter for some ODR/BER encoding
471 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
472 completeWAIS, odr_dumpBER.
474 Fixed bug in client.c which caused a crash when a scanResponse didn't
475 contain positionOfTerm.
477 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
478 * will cause an error in a client if a non-YAZ target sends both a
479 * list of Scan entries and non-surrogate diagnostics.
481 Retrieval module enhancements. Tag sets may be typed in the reference
482 to it. From the .abs-file the "tagset" directive takes a third optional
483 integer type for the tag set referenced. From a .tag-file the "include"
484 directive takes a third optional type as well. The old "type" directive
485 in the tag set itself is still recognized but acts as the default type
488 Backend interface change. Individual Scan terms returned from bend_scan
489 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
490 in include/backend.h.
492 Retrieval module enhancements. Multiple tag sets and attribute sets may
493 be specified in abstract syntax specs. Revised the error/warning for
494 logging messages reported by the retrieval module when reading the
497 Object Identifier system (oid_..) changed. The API is backwards
498 compatible but the oid-routines now allocates new OID's when needed.
499 Raw OID's may be specified in oid_getvalbyname.
501 YAZ now uses GNU configure to generate Makefile(s).
503 * Minor changes in some of the member names of DeleteResultSetRequest and
504 DeleteResultSetResponse. See include/proto.h.
506 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
507 and added member 'languages' in TargetInfo (which was missing).
509 Changed the way attribute sets are handled in the retrieval
510 module. These are now cached, just like the abstract syntaxes
513 Changed YAZ so that it links with compiled ASN.1.
515 Added Explain-schema definitions and mapping routines. The following
516 Explain categories have been implemented: AttributeDetails,
517 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
519 Fixed minor bug in Windows version of Server Library.
521 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
523 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
525 Added EXTERNAL: UNIverse Resource Report (non-standard).
527 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
528 ENUMERATED and SET OF.
530 * Added 'const' to some of the char pointer arguments for the
531 functions, data1_read_node, data1_getelementbytagname,
532 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
535 Fixed bug in data1_insert_taggeddata - the last_child member of
536 parent wasn't initialised.
538 * Changed data1_read_record and data1_read_node so that the supplied
539 "SGML"-buffer is read-only. In particular the resulting data1 - tree
540 doesn't refer to any parts of the "SGML"-buffer.
542 Fixed bug in server library (Windows version of statserv_remove).
544 * Changed code so that it compiles as C++. The type definition
545 of Odr_fun which is a member of Odr_arm was changed. The result is,
546 that an explicit typecast is needed for the fun pointer when
547 using Odr_arm - as in:
548 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
550 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
552 Implemented the new structured date and time definition as approved
553 by the ZIG. Added schemaId element to the specificTag in Espec-1
554 (also approved at the last ZIG). Thanks to RVDM.
556 Added some Object identifiers (RVDM).
558 Changed the Update Extended Service (RVDM).
560 Added command "refid" to client which specifies referenceId for
561 the following requests.
563 Implemented extended service handling for server. See ztest.c
564 for an example as well as backend.h. New handlers are registerd
567 * Changed interface for sort in server.
569 Added new members to statserv_options_block. It allows a server
570 to read options from another source than just the command line. Thanks
571 to Charles Woodfield.
573 * Changed definition of Z_Triple in file prt-grs.h - member boolean
574 renamed to zboolean. Some C++ compilers complained about the name.
576 Minor changes to gils.abs. Added index 's' (sort) on title
577 and date/time-last-modified.
581 Fixed bug in server library regarding inetd mode (-i). This bug
582 was introduced by release 1.4.
586 Added sort facility in client and backend server interface.
588 Fixed problem with dependencies in Makefile(s).
590 Fixed bugs for encoders/decoders of extended services and
593 Implemented sub-tree feature for schemas. Sub-trees are
594 referenced in *.abs-files. See explain.abs for an example
595 of the use of this feature.
597 Modified bib1.att; local attributes for ANY didn't include
598 ANY itself (only affects use of the retrieval module).
600 Fixed bug in plain SGML reader in function data1_read_node:
601 tags with prefix "var" was incorrectly interpreted as variants.
603 Added feature "sub-schemas" to enable references to - and definitions
604 of - group of elements.
606 * Removed member parent from type data1_element (in data1.h).
608 Implemented function odr_nullval() that returns the value of
611 * Removed member num_children from data1_node (in data1.h).
613 Made NT service interface part of the server library. The
614 function statserv_main uses the NT service when required and
615 calls the statserv_start / statserv_close routines.
617 Routine zget_SearchRequest and zget_PresentRequest fills
618 resultSetName/Id member with "default" instead of "Default".
620 Fixed memory leak in server. Request queue member wasn't freed.
622 Fixed nmem_exit so that memory is freed.
626 Revised the CCL parser utility to be thread safe.
628 Added function, oid_ent_to_oid, to replace the function
629 oid_getoidbyent, which is not thread safe.
631 * Added nmem_init and nmem_exit to initialize and release
632 NMEM resources. Function nmem_init should be called once in the
633 initial thread before NMEM/ODR is used. statserv.c and client.c
634 have been changed accordingly. The change was necessary to make
635 NMEM thread safe. The NMEM memory pool is shared amongst threads
636 in a process. Unix-based applications will still work fine without
639 Added NT Services interface for the the Z39.50 (statserv) Server.
640 Refer to the ztest.c source on the usage.
642 Windows 95/NT port using MSVC5.0. Project files are included in the
645 * Defined new 'global' handle for the retrieval (data1) system. The
646 new handled, data1_handle, describes the state of the data1 system.
647 This handle is passed as first argument to virtually all
648 data1 related routines. The functions data1_create and data1_destroy
649 creates and destroys a data1 handle respectively.
651 Added ODR encode stream member to all backend request structures
652 init, search, scan etc. This stream should be used to allocate all
653 memory used for the response when thread safe operation is needed.
655 Changed the comstack utility, cs_addstr, to be thread safe. The
656 returned hostname string returned by the function is now part the
659 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
660 function. The cs_straddr takes a COMSTACK handle as argument, so this
661 function must be used after cs_create and before bind/connect.
662 This function is thread safe.
664 Moved test server to 'ztest' directory - generic server code still
665 in 'server' directory.
667 Made prefix query (pquery.c) utility thread safe.
669 Added new function modifier YAZ_EXPORT to 'export' public DLL
670 functions when using windows (see include/yconfig.h).
672 Added definitions to the OID database (util/oid.c) (RVDM).
674 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
676 Added call to ccl_rpn_delete in client program.
678 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
679 release of RPN structure.
681 Added support for C++, headers uses extern "C" for public definitions.
682 With input from RVDM.
684 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
685 Thanks to Ronald van der Meer (RVDM).
687 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
689 Added support for private extensions to the OID database
690 (oid_setprivateoids()). Thanks to RVDM.
692 Added optional, physical ANY (key replication)
694 Fixed null-reference problem in GRS-1 output filter.
696 Proximity operator added to Prefix Query Format (PQF).
698 In test client command "base" accepts multiple databases.
700 Fixed bug in cs_close stack that caused trouble with WINSOCK.
704 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
706 Smallish bug-fixes in the new encoders/decoders (explain).

716 Added Update extended service.
718 Added SearchResult-1 additional info structure.
720 Added optional CCL (ISO8777) interpreter as separate module. Available
723 --- 1.2 1996/6/10 (1st anniversary release)
725 Added Summary record syntax. Lightly tested.
727 Added OPAC record syntax. Untested.
729 Added ResourceReport service encoders/decoders. Untested.
731 Fixed bug in z_Unit - wrong tagging on unitSystem.
733 Fixed bug in the DiagRecs decoder.
735 Added options for max PDU size and session timeout to frontend-server.
737 Added documentation of query-language parsers and other supporting utilities.
739 [frontend-server] Added Attribute set to the bend_scanrequest API.
741 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
742 surrogate diagnostics were generated.
744 [retrieval] Allow multiple local values for attribute.
746 [retrieval] Allow multiple attributes per element in .abs files. index type.
748 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
752 Minor changes, mostly specific to Zebra's requirements (retrieval)
756 Repaired bug in frontend server when running multiple listening
757 endpoints in dynamic mode.
759 z_External() now won't break if a known, ASN.1 value comes encapsulated
760 in an octet-string. The value will pass through unmodified in an Odr_oct.
762 Added a bit of code to the demo client to decode & display
763 ASN.1-structured records represented in the octet-aligned branch of
764 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
766 Added z_ext_getentbyref() to the ASN module. Doc updated.
768 * Completed the SCAN definition in the ASN module. This may break SCAN
769 code based on older YAZ-versions at compile-time. The fix is easy -
772 * Added 'displayTerm' and OtherInformation to the TermInfo structure
773 under the SCAN definition. Remember to initialize this, server-people.
775 Comstack should now support the WAIS protocol in TCP/IP mode. Note
776 that this does not extend to ODR and ASN.
778 Comstack allows insertion of established socket (primarily for
779 inetd-operation of servers). Doc updated.
781 Front-end server can now start from the inetd in TCP mode. Doc
788 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
789 the rank and record number.
791 Adjustments to the frontend server.
793 Fixed diagnostic BER dumper. It ignored the file argument.
797 Various changes to retrieval module.
799 Changed the union discriminators of the protocol files from enums to
800 ints paired with #defines.
802 *Changed oident.class to oident.oclass to avoid a reserved word in C++
805 *Changed operator in the RPN structure to 'roperator', again to avoid a
808 Fixed problems in Explain decoders/encoders.
812 Memory bug in log module fixed.
816 Occasional malloc() of 0 bytes fixed in d1_espec.c.
818 Bug in Explain DatabaseInfo module fixed.
820 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
824 The shift to v1.0 signals that we now consider the *core* functionality
825 of YAZ reasonably stable (the core being more or less equivalent to
826 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
827 tested (Explain not at all - though that will happen soonish).
829 Minor changes to code to support Windows port.
831 Various minor changes after we're getting to use GRS-1 & co. more.
833 Added Espec-1 format.
835 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
836 of the protocol and it cannot be selected when encoding (maps into 'string'
837 when decoding). Needed to talk to some servers.
839 Demo client can request simple element set names.
841 Added Diagnostic Format encoders/decoders.
843 Added simple Close handling to frontend server (no hooks for resource
844 reporting yet), and demonstration client.
846 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
850 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
851 handled incorrectly when records were requested in the searchResponse. This
852 will only affect you if you use the frontend-server.
854 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
855 Test-client will ask for and print GRS1. Ztest will return dummy records
858 Added Explain encoders/decoders to the service-level API. Untested.
860 Added Extended Services: Item Order encoders and decoders to the Service-
861 level API. Untested. We could use a recent copy of the pertinent bits
862 of the ILL protocol to add those bits.
864 Added diagnostic format 1 encoders/decoders to the service-level API.
867 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
868 odr_cons.c, which causes a more correct output.
870 Fixed handling of searchRequest in frontend server. NextResultSetPosition
871 was always set to 0 when no records were requested in the searchRequest.
873 * Added better external-handling. This shouldn't harm old code that
874 *encodes* externals. It can break code that looks for a
875 'single-ASN1-type' representation, since those types that are known
876 are now decoded immediately. Look at the SUTRS sample code in
877 seshigh.c and client.c. Documentation updated.
879 Handling of structured records in bend_fetchresponse. Length -1 marks
880 structured record, type is deduced from format field.
883 Fairly quick maintenance release to add SUTRS support.
885 Fixed handling of SUTRS records in the demonstration client.
887 * Added format field to the bend_fetchrequest and bend_fetchresponce
888 structures of the backend API (frontend server). When the record is
889 returned, the value of the format field is mapped to an OID. The
890 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
891 of the record. The special value VAL_NONE in the bend_request means
892 that no specific format was requested by the client. Documentation
893 updated accordingly. Test server (ztest) will return a fixed dummy
894 SUTRS record if your client requests SUTRS.
896 Documentation updated accordingly.
898 You can now set external libraries and RANLIB support in the top-level
902 First public release.
