1 Possible compatibility problems with earlier versions marked with '*'.
5 Support for SRW 1.0. This is an optional feature and requires
6 gSOAP to operate. Enable it by specifying --with-gsoap for
7 configure. SRW stuff is located in sub directory srw.
8 Example applications are located in srwapps.
10 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
12 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
13 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
15 ZOOM connections are SRW based if host/port is specified
16 as http. e.g. z = ZOOM_connection_new("http://myserver");
17 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
19 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
20 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
21 distance=n, order=true/false, relation=le, prox unit=word. If
22 n is omitted, distance 1 is used.
24 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
25 on Solaris. Patch from Ko van der Sloot.
27 New MARC decode API. All new functions operate on a yaz_marc_t
28 handle. The most important new functions are: yaz_marc_create,
29 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
30 decode and destroy respectively. Decoder can produce formats
31 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
32 include/yaz/marcdisp.h.
34 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
35 to UTF-8, UCS-32, wchar_t or Latin-1.
37 * Prototypes for yaz_iconv_-functions moved to separate header
38 include/yaz/yaz-iconv.h.
40 Make a few private functions 'static' in unix.c. This prevents
41 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
43 For ZOOM connection, the options targetImplementation{Id,Name,Version}
44 are set when Init Response is received.
46 New function ZOOM_connection_error_x similar to ZOOM_connection_error
47 but returns diagnostic set as well.
49 New function yaz_strerror which is a portable wrapper for
50 strerror/strerror_r/GetLastMessage.
52 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
53 is returned for MARC. If type is "oai", then OAI MARC is returned.
55 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
60 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
62 Fix bad race conditions on SIGTERM and terminate gracefully in
65 Move retrieval (data1) module to Zebra since nobody seems to be
68 Add GRS-1 render for ZOOM using same format as yaz-client.
72 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
74 Fix broken ESpec handling in data1 module.
76 SGML reader parses comments and makes them part of the data1 tree.
78 Added several type casts so that YAZ compiles as C++ code.
80 ZOOM didn't handle PDU encoding failures properly.
82 Added more Bib-1 diagnostics (approved extensions).
84 GNU configure: better check for iconv.
86 More portable use of accept, getpeername. Check for socklen_t. Use
87 int/size_t if socklen_t is not defined.
91 PQF parser rejects bad queries - including those with extra
92 characters in them. PQF parser used to silently ignore that.
93 Cleaner API for PQF added, which allows you to get detailed
94 error information for bad queries (see yaz/pquery.h).
96 Fixed bug in ZOOM_record_get for type "database".
98 Implemented mini iconv library supporting conversions between
99 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
101 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
105 Fixed ZOOM C record cache so that preferredRecordSyntax and
106 elementSetName is used to check for already fetched records.
110 Added three members in bend_initrequest structure to facilitate
111 character set negotiation.
113 Fixed a bug in frontend server that could cause indefinite
114 loops under rare conditions.
116 Revised character set utilities (charneg.h) so that encoding
117 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
119 For PQF, directive @term <type> sets term type for Scan/Search.
120 Here <type> is general, string, numeric, null. The term type
121 is inherited - just like @attr.
123 New call odr_set_charset that sets character set conversion for
124 international-strings on a ODR stream. Prototype is:
125 int odr_set_charset(ODR o, const char *to, const char *from);
126 The InternationalString is still represented as C string in YAZ
127 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
128 won't). On the protocol level, you can use any encoding.
130 Support for UNIX sockets in ZOOM.
132 Solaris recv sometimes returns errno == ENOENT. It is treated as
133 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
135 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
136 both client and server. Code by Morten Bøgeskov.
140 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
141 that they can be used directly from Visual Basic. You must recompile
142 your windows APP if you're using ZOOM.
144 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
145 Commands "lang" and "charset" sets language and character set respectively.
146 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
147 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
149 Attributes from multiple CCL fields may be OR'ed rather than merged
150 using directive "@field or". Fields are still merged by default -
151 equivalent to "@field merge".
153 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
156 Fixed bug in zget for parameter ExtendedServicesResponse.
162 Added PQF feature: '@attr type=value' may be written as '@type=value'.
164 Client displays USR.1:SearchResult-1 (hits per term).
166 Additional Search Info for search in Generic Frontend Server.
168 Fixed CCL parsing of "field=s".
170 WIN32 installer - using the excellent NSIS software from nullsoft.
172 Fixed CCL parsing of "field = - <number>".
174 Added function yaz_marc_decode that decodes MARC for line mode
175 display or XML (similar to that used by JZKit).
177 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
178 Z39.50. But ISO/ILL was, however.
180 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
181 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
183 http://lcweb.loc.gov/z3950/agency/amend/am2.html
184 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
188 New YAZ client features: Command completion and new commands:
189 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
190 Code provided by Jacob Poulsen.
192 New call oid_trav, that visits all registered OIDs via callback.
194 Function ZOOM_record_get now returns const char pointer rather than
195 void pointer. It saves a lot of type casts.
197 For YAZ client, command "auth" now allows you to set authentication
198 in IdPass style. It is enabled when three tokens are given - order
199 is user, group and password.
201 Fix memory leaks in MARC record handling for ZOOM.
203 New option for YAZ client, -k <kilobytes> that sets
204 maximum record size. Similar to -k option for generic frontend
205 server and yaz-ztest.
207 More fixes for scan. Non-zero stepSize handled. OID's fixes.
209 Prefix query parser reports "fail" when bad attribute set is given.
211 Fix in MARC decoder. Proximity logging. Fix for attribute set
212 in scan handler for server. Patches by Shigeru Ishida.
214 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
217 Configure option --with-openssl=<dir> now works when a directory is
218 specified. Patch provided by Morten Bøgeskov.
220 New option for YAZ client, -u <auth>, that sets authentication.
222 ZOOM fix: error information was sometimes "missing", since error
223 was cleared/reset too when it shouldn't.
225 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
229 Scan for ZOOM API. New object ZOOM_scanset. New functions
230 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
231 ZOOM_scanset_destroy.
233 New ZOOM function, ZOOM_connection_last_event, that returns type
234 of last event (such as "receive data", "send data", "apdu received",
237 New ZOOM option, schema, that specifies shema OID for retrieval.
239 New CCL feature. Qualifiers can be aliases for one or more
240 other qualifiers (if more than one is given, OR is used).
242 ZOOM uses named result sets if target supports it.
244 Two new YAZ client commands: . (dot, which sources a script of YAZ
245 client commands), and ! (to execute shell command.). Implemented
248 Working on Debian packages.
252 YAZ client enables named result sets only if target supports it.
254 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
256 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
257 with key="host" to get same result.
259 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
260 Function Z3950_resultset_record(s) returns references to records
261 "owned" by resultset. To become owner use Z3950_record_clone.
263 Function z_ext_record handles Extended Services. Thanks to
268 CCL Parser fix: ignore token comma when dealing with and-lists.
270 Documentation updates for COMSTACK.
272 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
273 Changed prototype Z3950_records. For some functions, int parameters
274 were changed to size_t.
276 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
279 New MARC decode/display function, marc_display_exl, which properly rejects
280 non-ISO2709 records. YAZ client uses it.
284 Fix bug: local attribute set wasn't set correctly in PQF strings.
288 * Old Z39.50 codecs no longer supported.
290 Added ZOOM C binding. See http://zoom.z3950.org/
292 Renamed states for COMSTACKs to avoid confusion with events.
294 Implemented cs_look and proper cs_rcvconnect.
296 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
298 Configure detects POSIX threads on OpenBSD.
300 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
301 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
303 When error is returned from present handler, non-surrogate diagnostic
304 is returned in present response (and fetch handler is no longer called).
306 * Minor adjustments to pquery parser (PQF). Token characters may be
307 escaped by using backslash (C-style).
309 PQF parser allows string attribute values to be specified. For @attr,
310 non-numeric characters after the equal-sign are treated as strings
311 (e.g. @attr 9=title).
313 CCL trunction character may be defined (@truncation in file)
315 * function zget_ExtendedServicesRequest sets waitAction to
316 waitIfPossible (was wait).
318 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
321 CCL operator names may be set in field definition files (CCL_bibset).
322 See ccl/bib1 for an example.
324 Fixes in ASN.1 compiler for C++ compatibility.
326 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
327 and "op_or" to avoid conflict with C++.
329 Fixed problem with GNU readline detection on Redhat 7.0.
331 Added step-size for Scan backend handler.
333 Fixed bug that made the frontend server crash when no attribute
334 set was specified for scan.
336 Front-end server automatically switches to original working directory
337 when installed as an NT service. Previously -w had to be specified to
340 Added extended attributes for retrieval module (data1), so that data1
341 records carry d1_readXML/SGML attributes. d1_read also supports
342 null-data rules ( <tag/>)
344 On UNIX when POSIX threads are available, a separate library libyazthread
345 is created. Programmers should link with that library and the yaz library
346 when using threads. The reason for the split was that some applications
347 on Linux, such as Apache, doesn't work well when using shared objects that
350 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
351 (or any frontend server) in SSL mode by specifying ssl: followed by
352 address. Only tested on UNIX.
354 Added feature for CCL module. Virtual structure s=al or s=ol generates
355 and-list and or-list respectively instead of phrase search.
359 * Added prefix "yaz_" for the functions log_init.., log_file.. and
360 log_mask_str. This was done to avoid name conflicts with other libraries
361 (such as other PHP extensions).
363 Added raw OID member for preferred record syntax (request_format_raw)
364 and returned record syntax (output_format_raw) for backend fetch method.
366 Config file yaz-config now accepts options so that it returns specific
367 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
369 Shared library support for UNIX using GNU libtool.
371 * Modified backend interface. Request/Response struct's replaced by
372 one read/write C struct. For example bend_fetchrequest and
373 bend_fetchresult have been replaced by single bend_fetch_rr struct.
374 Every handler - even search has to be registered in bend_init
375 handler. This means that the YAZ library no longer refers to
376 external functions and it makes it possible to make the whole
377 thing a single DLL/SO.
379 Added Segment handler for backend server.
381 Added Zmbol/Zebra administrative functions to YAZ client.
383 Threaded frontend server on UNIX (when POSIX Threads are available).
384 Starting the server with option -T enables multi-threading.
388 Added configure option --enable-comp/disable-comp to control use
389 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
390 located in sub directory asn.
392 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
393 in ${exec_prefix}/bin along with the other programs yaz-client and
396 GNU automake used to maintain makefiles.
400 Changed retrieval module so that we can load records with no abstract
401 syntax defined. Tagpaths in these records are fully composed of string
404 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
408 On UNIX, the generated makefile now supports a proper 'make install'.
409 The prefix can be set via GNU configure to set the install location
410 (default is /usr/local).
412 * YAZ programs client and ztest were renamed to yaz-client and
413 yaz-ztest to avoid conflicts when users install YAZ in "standard"
414 locations, such as /usr/bin,/usr/local/bin,etc.
416 * YAZ Header files were moved from include to include/yaz. YAZ Header
417 files are referred to as include <yaz/log.h> rather than <log.h>.
418 The YAZ include path (-I ..) is therefore the same as before. Programmers
419 should update their #include statements or use -Ipath/include/yaz
420 instead. The main motivation for doing this change is that YAZ header files
421 can be installed in "standard" locations /usr/include,/usr/local/include
422 without introducing conflicts, since ALL YAZ header files are stored
423 in subdirectory yaz (under /usr/include for example).
425 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
426 rather than project/workspace files. We switched because project files
427 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
430 Changed name of logging function, logf, to yaz_log, to prevent name
431 clash with some math-log functions. The YAZ header log.h defines logf
432 to yaz_log (#define) so there should be no incompatibilities by this
435 Added bend_start/bend_stop handlers for server. These handler are
436 called on start/stop of server. For windows they are called whenever
437 a service is started/stopped.
439 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
440 a fairly small ASN.1 compiler written in Tcl. The compiler is located
441 in util/yc.tcl. The auto-generated C code structures are, in a few
442 cases, incompatible with the old decoders. There are differences in the
443 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
444 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
445 The preprocessor variable ASN_COMPILED is defined when the compiled
446 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
447 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
448 wish to use the old encoders/decoders you can specify --disable-yc
451 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
452 version so that it supports both new - and old version of DB Update
454 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
455 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
456 change. The name parameter can be set to 0 in which no name is specified
457 for the construction. The macros odr_implicit and odr_explicit sets name
458 parameter to zero for the construction involved. New macros
459 odr_implicit_tag and odr_explicit_tag are similar to the others,
460 except that a name parameter is added. For programmers' that don't use
461 ODR they probably only need to change the call to z_APDU and z_External.
463 Added access control facility by interfacing the TCP wrapper library.
464 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
465 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
466 name of the daemon and enables the access control as specified in
467 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
469 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
470 den Dool <H.M.vdnDool@kub.nl>.
472 Added reference ID parameter to most functions in server API - refer
473 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
475 Changed name of ccl library to libccl.a (was ccl.a).
477 Fixed bug in decoder for Explain (Category TargetInfo).
479 Added support for GNU readline in client. Thanks to Jacob Poulsen
480 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
482 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
483 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
484 IMPLEMENTATION! This change was made to the development version before
485 the ZIG decided to retract the amendment. If any users MUST be
486 compatible with the original Update definition, PLEASE CONTACT US, and
487 we will include a separate definition corresponding to the old Update
488 ES. Note that because of the change to the ASN.1 of the
489 TaskPackageRecordStructure we cannot define a single structure that
490 will support both versions.
492 * Added const modifier to buffer parameter for some ODR/BER encoding
493 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
494 completeWAIS, odr_dumpBER.
496 Fixed bug in client.c which caused a crash when a scanResponse didn't
497 contain positionOfTerm.
499 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
500 * will cause an error in a client if a non-YAZ target sends both a
501 * list of Scan entries and non-surrogate diagnostics.
503 Retrieval module enhancements. Tag sets may be typed in the reference
504 to it. From the .abs-file the "tagset" directive takes a third optional
505 integer type for the tag set referenced. From a .tag-file the "include"
506 directive takes a third optional type as well. The old "type" directive
507 in the tag set itself is still recognized but acts as the default type
510 Backend interface change. Individual Scan terms returned from bend_scan
511 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
512 in include/backend.h.
514 Retrieval module enhancements. Multiple tag sets and attribute sets may
515 be specified in abstract syntax specs. Revised the error/warning for
516 logging messages reported by the retrieval module when reading the
519 Object Identifier system (oid_..) changed. The API is backwards
520 compatible but the oid-routines now allocates new OID's when needed.
521 Raw OID's may be specified in oid_getvalbyname.
523 YAZ now uses GNU configure to generate Makefile(s).
525 * Minor changes in some of the member names of DeleteResultSetRequest and
526 DeleteResultSetResponse. See include/proto.h.
528 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
529 and added member 'languages' in TargetInfo (which was missing).
531 Changed the way attribute sets are handled in the retrieval
532 module. These are now cached, just like the abstract syntaxes
535 Changed YAZ so that it links with compiled ASN.1.
537 Added Explain-schema definitions and mapping routines. The following
538 Explain categories have been implemented: AttributeDetails,
539 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
541 Fixed minor bug in Windows version of Server Library.
543 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
545 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
547 Added EXTERNAL: UNIverse Resource Report (non-standard).
549 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
550 ENUMERATED and SET OF.
552 * Added 'const' to some of the char pointer arguments for the
553 functions, data1_read_node, data1_getelementbytagname,
554 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
557 Fixed bug in data1_insert_taggeddata - the last_child member of
558 parent wasn't initialised.
560 * Changed data1_read_record and data1_read_node so that the supplied
561 "SGML"-buffer is read-only. In particular the resulting data1 - tree
562 doesn't refer to any parts of the "SGML"-buffer.
564 Fixed bug in server library (Windows version of statserv_remove).
566 * Changed code so that it compiles as C++. The type definition
567 of Odr_fun which is a member of Odr_arm was changed. The result is,
568 that an explicit typecast is needed for the fun pointer when
569 using Odr_arm - as in:
570 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
572 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
574 Implemented the new structured date and time definition as approved
575 by the ZIG. Added schemaId element to the specificTag in Espec-1
576 (also approved at the last ZIG). Thanks to RVDM.
578 Added some Object identifiers (RVDM).
580 Changed the Update Extended Service (RVDM).
582 Added command "refid" to client which specifies referenceId for
583 the following requests.
585 Implemented extended service handling for server. See ztest.c
586 for an example as well as backend.h. New handlers are registerd
589 * Changed interface for sort in server.
591 Added new members to statserv_options_block. It allows a server
592 to read options from another source than just the command line. Thanks
593 to Charles Woodfield.
595 * Changed definition of Z_Triple in file prt-grs.h - member boolean
596 renamed to zboolean. Some C++ compilers complained about the name.
598 Minor changes to gils.abs. Added index 's' (sort) on title
599 and date/time-last-modified.
603 Fixed bug in server library regarding inetd mode (-i). This bug
604 was introduced by release 1.4.
608 Added sort facility in client and backend server interface.
610 Fixed problem with dependencies in Makefile(s).
612 Fixed bugs for encoders/decoders of extended services and
615 Implemented sub-tree feature for schemas. Sub-trees are
616 referenced in *.abs-files. See explain.abs for an example
617 of the use of this feature.
619 Modified bib1.att; local attributes for ANY didn't include
620 ANY itself (only affects use of the retrieval module).
622 Fixed bug in plain SGML reader in function data1_read_node:
623 tags with prefix "var" was incorrectly interpreted as variants.
625 Added feature "sub-schemas" to enable references to - and definitions
626 of - group of elements.
628 * Removed member parent from type data1_element (in data1.h).
630 Implemented function odr_nullval() that returns the value of
633 * Removed member num_children from data1_node (in data1.h).
635 Made NT service interface part of the server library. The
636 function statserv_main uses the NT service when required and
637 calls the statserv_start / statserv_close routines.
639 Routine zget_SearchRequest and zget_PresentRequest fills
640 resultSetName/Id member with "default" instead of "Default".
642 Fixed memory leak in server. Request queue member wasn't freed.
644 Fixed nmem_exit so that memory is freed.
648 Revised the CCL parser utility to be thread safe.
650 Added function, oid_ent_to_oid, to replace the function
651 oid_getoidbyent, which is not thread safe.
653 * Added nmem_init and nmem_exit to initialize and release
654 NMEM resources. Function nmem_init should be called once in the
655 initial thread before NMEM/ODR is used. statserv.c and client.c
656 have been changed accordingly. The change was necessary to make
657 NMEM thread safe. The NMEM memory pool is shared amongst threads
658 in a process. Unix-based applications will still work fine without
661 Added NT Services interface for the the Z39.50 (statserv) Server.
662 Refer to the ztest.c source on the usage.
664 Windows 95/NT port using MSVC5.0. Project files are included in the
667 * Defined new 'global' handle for the retrieval (data1) system. The
668 new handled, data1_handle, describes the state of the data1 system.
669 This handle is passed as first argument to virtually all
670 data1 related routines. The functions data1_create and data1_destroy
671 creates and destroys a data1 handle respectively.
673 Added ODR encode stream member to all backend request structures
674 init, search, scan etc. This stream should be used to allocate all
675 memory used for the response when thread safe operation is needed.
677 Changed the comstack utility, cs_addstr, to be thread safe. The
678 returned hostname string returned by the function is now part the
681 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
682 function. The cs_straddr takes a COMSTACK handle as argument, so this
683 function must be used after cs_create and before bind/connect.
684 This function is thread safe.
686 Moved test server to 'ztest' directory - generic server code still
687 in 'server' directory.
689 Made prefix query (pquery.c) utility thread safe.
691 Added new function modifier YAZ_EXPORT to 'export' public DLL
692 functions when using windows (see include/yconfig.h).
694 Added definitions to the OID database (util/oid.c) (RVDM).
696 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
698 Added call to ccl_rpn_delete in client program.
700 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
701 release of RPN structure.
703 Added support for C++, headers uses extern "C" for public definitions.
704 With input from RVDM.
706 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
707 Thanks to Ronald van der Meer (RVDM).
709 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
711 Added support for private extensions to the OID database
712 (oid_setprivateoids()). Thanks to RVDM.
714 Added optional, physical ANY (key replication)
716 Fixed null-reference problem in GRS-1 output filter.
718 Proximity operator added to Prefix Query Format (PQF).
720 In test client command "base" accepts multiple databases.
722 Fixed bug in cs_close stack that caused trouble with WINSOCK.
726 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
728 Smallish bug-fixes in the new encoders/decoders (explain).
730 Bug fixed in DeleteRequest.
732 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
734 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
736 Added SOIF syntax (using private OID for now) to retrieval module and client.
738 Added Update extended service.
740 Added SearchResult-1 additional info structure.
742 Added optional CCL (ISO8777) interpreter as separate module. Available
745 --- 1.2 1996/6/10 (1st anniversary release)
747 Added Summary record syntax. Lightly tested.
749 Added OPAC record syntax. Untested.
751 Added ResourceReport service encoders/decoders. Untested.
753 Fixed bug in z_Unit - wrong tagging on unitSystem.
755 Fixed bug in the DiagRecs decoder.
757 Added options for max PDU size and session timeout to frontend-server.
759 Added documentation of query-language parsers and other supporting utilities.
761 [frontend-server] Added Attribute set to the bend_scanrequest API.
763 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
764 surrogate diagnostics were generated.
766 [retrieval] Allow multiple local values for attribute.
768 [retrieval] Allow multiple attributes per element in .abs files. index type.
770 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
774 Minor changes, mostly specific to Zebra's requirements (retrieval)
778 Repaired bug in frontend server when running multiple listening
779 endpoints in dynamic mode.
781 z_External() now won't break if a known, ASN.1 value comes encapsulated
782 in an octet-string. The value will pass through unmodified in an Odr_oct.
784 Added a bit of code to the demo client to decode & display
785 ASN.1-structured records represented in the octet-aligned branch of
786 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
788 Added z_ext_getentbyref() to the ASN module. Doc updated.
790 * Completed the SCAN definition in the ASN module. This may break SCAN
791 code based on older YAZ-versions at compile-time. The fix is easy -
794 * Added 'displayTerm' and OtherInformation to the TermInfo structure
795 under the SCAN definition. Remember to initialize this, server-people.
797 Comstack should now support the WAIS protocol in TCP/IP mode. Note
798 that this does not extend to ODR and ASN.
800 Comstack allows insertion of established socket (primarily for
801 inetd-operation of servers). Doc updated.
803 Front-end server can now start from the inetd in TCP mode. Doc
810 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
811 the rank and record number.
813 Adjustments to the frontend server.
815 Fixed diagnostic BER dumper. It ignored the file argument.
819 Various changes to retrieval module.
821 Changed the union discriminators of the protocol files from enums to
822 ints paired with #defines.
824 *Changed oident.class to oident.oclass to avoid a reserved word in C++
827 *Changed operator in the RPN structure to 'roperator', again to avoid a
830 Fixed problems in Explain decoders/encoders.
834 Memory bug in log module fixed.
838 Occasional malloc() of 0 bytes fixed in d1_espec.c.
840 Bug in Explain DatabaseInfo module fixed.
842 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
846 The shift to v1.0 signals that we now consider the *core* functionality
847 of YAZ reasonably stable (the core being more or less equivalent to
848 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
849 tested (Explain not at all - though that will happen soonish).
851 Minor changes to code to support Windows port.
853 Various minor changes after we're getting to use GRS-1 & co. more.
855 Added Espec-1 format.
857 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
858 of the protocol and it cannot be selected when encoding (maps into 'string'
859 when decoding). Needed to talk to some servers.
861 Demo client can request simple element set names.
863 Added Diagnostic Format encoders/decoders.
865 Added simple Close handling to frontend server (no hooks for resource
866 reporting yet), and demonstration client.
868 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
872 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
873 handled incorrectly when records were requested in the searchResponse. This
874 will only affect you if you use the frontend-server.
876 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
877 Test-client will ask for and print GRS1. Ztest will return dummy records
880 Added Explain encoders/decoders to the service-level API. Untested.
882 Added Extended Services: Item Order encoders and decoders to the Service-
883 level API. Untested. We could use a recent copy of the pertinent bits
884 of the ILL protocol to add those bits.
886 Added diagnostic format 1 encoders/decoders to the service-level API.
889 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
890 odr_cons.c, which causes a more correct output.
892 Fixed handling of searchRequest in frontend server. NextResultSetPosition
893 was always set to 0 when no records were requested in the searchRequest.
895 * Added better external-handling. This shouldn't harm old code that
896 *encodes* externals. It can break code that looks for a
897 'single-ASN1-type' representation, since those types that are known
898 are now decoded immediately. Look at the SUTRS sample code in
899 seshigh.c and client.c. Documentation updated.
901 Handling of structured records in bend_fetchresponse. Length -1 marks
902 structured record, type is deduced from format field.
905 Fairly quick maintenance release to add SUTRS support.
907 Fixed handling of SUTRS records in the demonstration client.
909 * Added format field to the bend_fetchrequest and bend_fetchresponce
910 structures of the backend API (frontend server). When the record is
911 returned, the value of the format field is mapped to an OID. The
912 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
913 of the record. The special value VAL_NONE in the bend_request means
914 that no specific format was requested by the client. Documentation
915 updated accordingly. Test server (ztest) will return a fixed dummy
916 SUTRS record if your client requests SUTRS.
918 Documentation updated accordingly.
920 You can now set external libraries and RANLIB support in the top-level
924 First public release.
