1 Possible compatibility problems with earlier versions marked with '*'.
5 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
6 on Solaris. Patch from Ko van der Sloot.
8 New MARC decode API. All new functions operate on a yaz_marc_t
9 handle. The most important new functions are: yaz_marc_create,
10 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
11 decode and destroy respectively. Decoder can produce formats
12 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
13 include/yaz/marcdisp.h.
15 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
16 to UTF-8, UCS-32, wchar_t or Latin-1.
18 * Prototypes for yaz_iconv_-functions moved to separate header
19 include/yaz/yaz-iconv.h.
21 Make a few private functions 'static' in unix.c. This prevents
22 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
24 For ZOOM connection, the options targetImplementation{Id,Name,Version}
25 are set when Init Response is received.
27 New function ZOOM_connection_error_x similar to ZOOM_connection_error
28 but returns diagnostic set as well.
30 New function yaz_strerror which is a portable wrapper for
31 strerror/strerror_r/GetLastMessage.
33 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
34 is returned for MARC. If type is "oai", then OAI MARC is returned.
36 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
41 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
43 Fix bad race conditions on SIGTERM and terminate gracefully in
46 Move retrieval (data1) module to Zebra since nobody seems to be
49 Add GRS-1 render for ZOOM using same format as yaz-client.
53 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
55 Fix broken ESpec handling in data1 module.
57 SGML reader parses comments and makes them part of the data1 tree.
59 Added several type casts so that YAZ compiles as C++ code.
61 ZOOM didn't handle PDU encoding failures properly.
63 Added more Bib-1 diagnostics (approved extensions).
65 GNU configure: better check for iconv.
67 More portable use of accept, getpeername. Check for socklen_t. Use
68 int/size_t if socklen_t is not defined.
72 PQF parser rejects bad queries - including those with extra
73 characters in them. PQF parser used to silently ignore that.
74 Cleaner API for PQF added, which allows you to get detailed
75 error information for bad queries (see yaz/pquery.h).
77 Fixed bug in ZOOM_record_get for type "database".
79 Implemented mini iconv library supporting conversions between
80 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
82 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
86 Fixed ZOOM C record cache so that preferredRecordSyntax and
87 elementSetName is used to check for already fetched records.
91 Added three members in bend_initrequest structure to facilitate
92 character set negotiation.
94 Fixed a bug in frontend server that could cause indefinite
95 loops under rare conditions.
97 Revised character set utilities (charneg.h) so that encoding
98 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
100 For PQF, directive @term <type> sets term type for Scan/Search.
101 Here <type> is general, string, numeric, null. The term type
102 is inherited - just like @attr.
104 New call odr_set_charset that sets character set conversion for
105 international-strings on a ODR stream. Prototype is:
106 int odr_set_charset(ODR o, const char *to, const char *from);
107 The InternationalString is still represented as C string in YAZ
108 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
109 won't). On the protocol level, you can use any encoding.
111 Support for UNIX sockets in ZOOM.
113 Solaris recv sometimes returns errno == ENOENT. It is treated as
114 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
116 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
117 both client and server. Code by Morten Bøgeskov.
121 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
122 that they can be used directly from Visual Basic. You must recompile
123 your windows APP if you're using ZOOM.
125 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
126 Commands "lang" and "charset" sets language and character set respectively.
127 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
128 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
130 Attributes from multiple CCL fields may be OR'ed rather than merged
131 using directive "@field or". Fields are still merged by default -
132 equivalent to "@field merge".
134 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
137 Fixed bug in zget for parameter ExtendedServicesResponse.
143 Added PQF feature: '@attr type=value' may be written as '@type=value'.
145 Client displays USR.1:SearchResult-1 (hits per term).
147 Additional Search Info for search in Generic Frontend Server.
149 Fixed CCL parsing of "field=s".
151 WIN32 installer - using the excellent NSIS software from nullsoft.
153 Fixed CCL parsing of "field = - <number>".
155 Added function yaz_marc_decode that decodes MARC for line mode
156 display or XML (similar to that used by JZKit).
158 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
159 Z39.50. But ISO/ILL was, however.
161 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
162 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
164 http://lcweb.loc.gov/z3950/agency/amend/am2.html
165 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
169 New YAZ client features: Command completion and new commands:
170 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
171 Code provided by Jacob Poulsen.
173 New call oid_trav, that visits all registered OIDs via callback.
175 Function ZOOM_record_get now returns const char pointer rather than
176 void pointer. It saves a lot of type casts.
178 For YAZ client, command "auth" now allows you to set authentication
179 in IdPass style. It is enabled when three tokens are given - order
180 is user, group and password.
182 Fix memory leaks in MARC record handling for ZOOM.
184 New option for YAZ client, -k <kilobytes> that sets
185 maximum record size. Similar to -k option for generic frontend
186 server and yaz-ztest.
188 More fixes for scan. Non-zero stepSize handled. OID's fixes.
190 Prefix query parser reports "fail" when bad attribute set is given.
192 Fix in MARC decoder. Proximity logging. Fix for attribute set
193 in scan handler for server. Patches by Shigeru Ishida.
195 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
198 Configure option --with-openssl=<dir> now works when a directory is
199 specified. Patch provided by Morten Bøgeskov.
201 New option for YAZ client, -u <auth>, that sets authentication.
203 ZOOM fix: error information was sometimes "missing", since error
204 was cleared/reset too when it shouldn't.
206 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
210 Scan for ZOOM API. New object ZOOM_scanset. New functions
211 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
212 ZOOM_scanset_destroy.
214 New ZOOM function, ZOOM_connection_last_event, that returns type
215 of last event (such as "receive data", "send data", "apdu received",
218 New ZOOM option, schema, that specifies shema OID for retrieval.
220 New CCL feature. Qualifiers can be aliases for one or more
221 other qualifiers (if more than one is given, OR is used).
223 ZOOM uses named result sets if target supports it.
225 Two new YAZ client commands: . (dot, which sources a script of YAZ
226 client commands), and ! (to execute shell command.). Implemented
229 Working on Debian packages.
233 YAZ client enables named result sets only if target supports it.
235 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
237 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
238 with key="host" to get same result.
240 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
241 Function Z3950_resultset_record(s) returns references to records
242 "owned" by resultset. To become owner use Z3950_record_clone.
244 Function z_ext_record handles Extended Services. Thanks to
249 CCL Parser fix: ignore token comma when dealing with and-lists.
251 Documentation updates for COMSTACK.
253 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
254 Changed prototype Z3950_records. For some functions, int parameters
255 were changed to size_t.
257 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
260 New MARC decode/display function, marc_display_exl, which properly rejects
261 non-ISO2709 records. YAZ client uses it.
265 Fix bug: local attribute set wasn't set correctly in PQF strings.
269 * Old Z39.50 codecs no longer supported.
271 Added ZOOM C binding. See http://zoom.z3950.org/
273 Renamed states for COMSTACKs to avoid confusion with events.
275 Implemented cs_look and proper cs_rcvconnect.
277 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
279 Configure detects POSIX threads on OpenBSD.
281 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
282 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
284 When error is returned from present handler, non-surrogate diagnostic
285 is returned in present response (and fetch handler is no longer called).
287 * Minor adjustments to pquery parser (PQF). Token characters may be
288 escaped by using backslash (C-style).
290 PQF parser allows string attribute values to be specified. For @attr,
291 non-numeric characters after the equal-sign are treated as strings
292 (e.g. @attr 9=title).
294 CCL trunction character may be defined (@truncation in file)
296 * function zget_ExtendedServicesRequest sets waitAction to
297 waitIfPossible (was wait).
299 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
302 CCL operator names may be set in field definition files (CCL_bibset).
303 See ccl/bib1 for an example.
305 Fixes in ASN.1 compiler for C++ compatibility.
307 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
308 and "op_or" to avoid conflict with C++.
310 Fixed problem with GNU readline detection on Redhat 7.0.
312 Added step-size for Scan backend handler.
314 Fixed bug that made the frontend server crash when no attribute
315 set was specified for scan.
317 Front-end server automatically switches to original working directory
318 when installed as an NT service. Previously -w had to be specified to
321 Added extended attributes for retrieval module (data1), so that data1
322 records carry d1_readXML/SGML attributes. d1_read also supports
323 null-data rules ( <tag/>)
325 On UNIX when POSIX threads are available, a separate library libyazthread
326 is created. Programmers should link with that library and the yaz library
327 when using threads. The reason for the split was that some applications
328 on Linux, such as Apache, doesn't work well when using shared objects that
331 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
332 (or any frontend server) in SSL mode by specifying ssl: followed by
333 address. Only tested on UNIX.
335 Added feature for CCL module. Virtual structure s=al or s=ol generates
336 and-list and or-list respectively instead of phrase search.
340 * Added prefix "yaz_" for the functions log_init.., log_file.. and
341 log_mask_str. This was done to avoid name conflicts with other libraries
342 (such as other PHP extensions).
344 Added raw OID member for preferred record syntax (request_format_raw)
345 and returned record syntax (output_format_raw) for backend fetch method.
347 Config file yaz-config now accepts options so that it returns specific
348 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
350 Shared library support for UNIX using GNU libtool.
352 * Modified backend interface. Request/Response struct's replaced by
353 one read/write C struct. For example bend_fetchrequest and
354 bend_fetchresult have been replaced by single bend_fetch_rr struct.
355 Every handler - even search has to be registered in bend_init
356 handler. This means that the YAZ library no longer refers to
357 external functions and it makes it possible to make the whole
358 thing a single DLL/SO.
360 Added Segment handler for backend server.
362 Added Zmbol/Zebra administrative functions to YAZ client.
364 Threaded frontend server on UNIX (when POSIX Threads are available).
365 Starting the server with option -T enables multi-threading.
369 Added configure option --enable-comp/disable-comp to control use
370 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
371 located in sub directory asn.
373 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
374 in ${exec_prefix}/bin along with the other programs yaz-client and
377 GNU automake used to maintain makefiles.
381 Changed retrieval module so that we can load records with no abstract
382 syntax defined. Tagpaths in these records are fully composed of string
385 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
389 On UNIX, the generated makefile now supports a proper 'make install'.
390 The prefix can be set via GNU configure to set the install location
391 (default is /usr/local).
393 * YAZ programs client and ztest were renamed to yaz-client and
394 yaz-ztest to avoid conflicts when users install YAZ in "standard"
395 locations, such as /usr/bin,/usr/local/bin,etc.
397 * YAZ Header files were moved from include to include/yaz. YAZ Header
398 files are referred to as include <yaz/log.h> rather than <log.h>.
399 The YAZ include path (-I ..) is therefore the same as before. Programmers
400 should update their #include statements or use -Ipath/include/yaz
401 instead. The main motivation for doing this change is that YAZ header files
402 can be installed in "standard" locations /usr/include,/usr/local/include
403 without introducing conflicts, since ALL YAZ header files are stored
404 in subdirectory yaz (under /usr/include for example).
406 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
407 rather than project/workspace files. We switched because project files
408 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
411 Changed name of logging function, logf, to yaz_log, to prevent name
412 clash with some math-log functions. The YAZ header log.h defines logf
413 to yaz_log (#define) so there should be no incompatibilities by this
416 Added bend_start/bend_stop handlers for server. These handler are
417 called on start/stop of server. For windows they are called whenever
418 a service is started/stopped.
420 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
421 a fairly small ASN.1 compiler written in Tcl. The compiler is located
422 in util/yc.tcl. The auto-generated C code structures are, in a few
423 cases, incompatible with the old decoders. There are differences in the
424 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
425 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
426 The preprocessor variable ASN_COMPILED is defined when the compiled
427 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
428 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
429 wish to use the old encoders/decoders you can specify --disable-yc
432 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
433 version so that it supports both new - and old version of DB Update
435 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
436 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
437 change. The name parameter can be set to 0 in which no name is specified
438 for the construction. The macros odr_implicit and odr_explicit sets name
439 parameter to zero for the construction involved. New macros
440 odr_implicit_tag and odr_explicit_tag are similar to the others,
441 except that a name parameter is added. For programmers' that don't use
442 ODR they probably only need to change the call to z_APDU and z_External.
444 Added access control facility by interfacing the TCP wrapper library.
445 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
446 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
447 name of the daemon and enables the access control as specified in
448 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
450 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
451 den Dool <H.M.vdnDool@kub.nl>.
453 Added reference ID parameter to most functions in server API - refer
454 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
456 Changed name of ccl library to libccl.a (was ccl.a).
458 Fixed bug in decoder for Explain (Category TargetInfo).
460 Added support for GNU readline in client. Thanks to Jacob Poulsen
461 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
463 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
464 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
465 IMPLEMENTATION! This change was made to the development version before
466 the ZIG decided to retract the amendment. If any users MUST be
467 compatible with the original Update definition, PLEASE CONTACT US, and
468 we will include a separate definition corresponding to the old Update
469 ES. Note that because of the change to the ASN.1 of the
470 TaskPackageRecordStructure we cannot define a single structure that
471 will support both versions.
473 * Added const modifier to buffer parameter for some ODR/BER encoding
474 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
475 completeWAIS, odr_dumpBER.
477 Fixed bug in client.c which caused a crash when a scanResponse didn't
478 contain positionOfTerm.
480 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
481 * will cause an error in a client if a non-YAZ target sends both a
482 * list of Scan entries and non-surrogate diagnostics.
484 Retrieval module enhancements. Tag sets may be typed in the reference
485 to it. From the .abs-file the "tagset" directive takes a third optional
486 integer type for the tag set referenced. From a .tag-file the "include"
487 directive takes a third optional type as well. The old "type" directive
488 in the tag set itself is still recognized but acts as the default type
491 Backend interface change. Individual Scan terms returned from bend_scan
492 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
493 in include/backend.h.
495 Retrieval module enhancements. Multiple tag sets and attribute sets may
496 be specified in abstract syntax specs. Revised the error/warning for
497 logging messages reported by the retrieval module when reading the
500 Object Identifier system (oid_..) changed. The API is backwards
501 compatible but the oid-routines now allocates new OID's when needed.
502 Raw OID's may be specified in oid_getvalbyname.
504 YAZ now uses GNU configure to generate Makefile(s).
506 * Minor changes in some of the member names of DeleteResultSetRequest and
507 DeleteResultSetResponse. See include/proto.h.
509 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
510 and added member 'languages' in TargetInfo (which was missing).
512 Changed the way attribute sets are handled in the retrieval
513 module. These are now cached, just like the abstract syntaxes
516 Changed YAZ so that it links with compiled ASN.1.
518 Added Explain-schema definitions and mapping routines. The following
519 Explain categories have been implemented: AttributeDetails,
520 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
522 Fixed minor bug in Windows version of Server Library.
524 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
526 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
528 Added EXTERNAL: UNIverse Resource Report (non-standard).
530 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
531 ENUMERATED and SET OF.
533 * Added 'const' to some of the char pointer arguments for the
534 functions, data1_read_node, data1_getelementbytagname,
535 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
538 Fixed bug in data1_insert_taggeddata - the last_child member of
539 parent wasn't initialised.
541 * Changed data1_read_record and data1_read_node so that the supplied
542 "SGML"-buffer is read-only. In particular the resulting data1 - tree
543 doesn't refer to any parts of the "SGML"-buffer.
545 Fixed bug in server library (Windows version of statserv_remove).
547 * Changed code so that it compiles as C++. The type definition
548 of Odr_fun which is a member of Odr_arm was changed. The result is,
549 that an explicit typecast is needed for the fun pointer when
550 using Odr_arm - as in:
551 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
553 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
555 Implemented the new structured date and time definition as approved
556 by the ZIG. Added schemaId element to the specificTag in Espec-1
557 (also approved at the last ZIG). Thanks to RVDM.
559 Added some Object identifiers (RVDM).
561 Changed the Update Extended Service (RVDM).
563 Added command "refid" to client which specifies referenceId for
564 the following requests.
566 Implemented extended service handling for server. See ztest.c
567 for an example as well as backend.h. New handlers are registerd
570 * Changed interface for sort in server.
572 Added new members to statserv_options_block. It allows a server
573 to read options from another source than just the command line. Thanks
574 to Charles Woodfield.
576 * Changed definition of Z_Triple in file prt-grs.h - member boolean
577 renamed to zboolean. Some C++ compilers complained about the name.
579 Minor changes to gils.abs. Added index 's' (sort) on title
580 and date/time-last-modified.
584 Fixed bug in server library regarding inetd mode (-i). This bug
585 was introduced by release 1.4.
589 Added sort facility in client and backend server interface.
591 Fixed problem with dependencies in Makefile(s).
593 Fixed bugs for encoders/decoders of extended services and
596 Implemented sub-tree feature for schemas. Sub-trees are
597 referenced in *.abs-files. See explain.abs for an example
598 of the use of this feature.
600 Modified bib1.att; local attributes for ANY didn't include
601 ANY itself (only affects use of the retrieval module).
603 Fixed bug in plain SGML reader in function data1_read_node:
604 tags with prefix "var" was incorrectly interpreted as variants.
606 Added feature "sub-schemas" to enable references to - and definitions
607 of - group of elements.
609 * Removed member parent from type data1_element (in data1.h).
611 Implemented function odr_nullval() that returns the value of
614 * Removed member num_children from data1_node (in data1.h).
616 Made NT service interface part of the server library. The
617 function statserv_main uses the NT service when required and
618 calls the statserv_start / statserv_close routines.
620 Routine zget_SearchRequest and zget_PresentRequest fills
621 resultSetName/Id member with "default" instead of "Default".
623 Fixed memory leak in server. Request queue member wasn't freed.
625 Fixed nmem_exit so that memory is freed.
629 Revised the CCL parser utility to be thread safe.
631 Added function, oid_ent_to_oid, to replace the function
632 oid_getoidbyent, which is not thread safe.
634 * Added nmem_init and nmem_exit to initialize and release
635 NMEM resources. Function nmem_init should be called once in the
636 initial thread before NMEM/ODR is used. statserv.c and client.c
637 have been changed accordingly. The change was necessary to make
638 NMEM thread safe. The NMEM memory pool is shared amongst threads
639 in a process. Unix-based applications will still work fine without
642 Added NT Services interface for the the Z39.50 (statserv) Server.
643 Refer to the ztest.c source on the usage.
645 Windows 95/NT port using MSVC5.0. Project files are included in the
648 * Defined new 'global' handle for the retrieval (data1) system. The
649 new handled, data1_handle, describes the state of the data1 system.
650 This handle is passed as first argument to virtually all
651 data1 related routines. The functions data1_create and data1_destroy
652 creates and destroys a data1 handle respectively.
654 Added ODR encode stream member to all backend request structures
655 init, search, scan etc. This stream should be used to allocate all
656 memory used for the response when thread safe operation is needed.
658 Changed the comstack utility, cs_addstr, to be thread safe. The
659 returned hostname string returned by the function is now part the
662 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
663 function. The cs_straddr takes a COMSTACK handle as argument, so this
664 function must be used after cs_create and before bind/connect.
665 This function is thread safe.
667 Moved test server to 'ztest' directory - generic server code still
668 in 'server' directory.
670 Made prefix query (pquery.c) utility thread safe.
672 Added new function modifier YAZ_EXPORT to 'export' public DLL
673 functions when using windows (see include/yconfig.h).
675 Added definitions to the OID database (util/oid.c) (RVDM).
677 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
679 Added call to ccl_rpn_delete in client program.
681 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
682 release of RPN structure.
684 Added support for C++, headers uses extern "C" for public definitions.
685 With input from RVDM.
687 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
688 Thanks to Ronald van der Meer (RVDM).
690 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.

693 (oid_setprivateoids()). Thanks to RVDM.
695 Added optional, physical ANY (key replication)
697 Fixed null-reference problem in GRS-1 output filter.
699 Proximity operator added to Prefix Query Format (PQF).

726 --- 1.2 1996/6/10 (1st anniversary release)
728 Added Summary record syntax. Lightly tested.
730 Added OPAC record syntax. Untested.
732 Added ResourceReport service encoders/decoders. Untested.
734 Fixed bug in z_Unit - wrong tagging on unitSystem.
736 Fixed bug in the DiagRecs decoder.
738 Added options for max PDU size and session timeout to frontend-server.
740 Added documentation of query-language parsers and other supporting utilities.
742 [frontend-server] Added Attribute set to the bend_scanrequest API.
744 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
745 surrogate diagnostics were generated.
747 [retrieval] Allow multiple local values for attribute.
749 [retrieval] Allow multiple attributes per element in .abs files. index type.
751 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
755 Minor changes, mostly specific to Zebra's requirements (retrieval)
759 Repaired bug in frontend server when running multiple listening
760 endpoints in dynamic mode.
762 z_External() now won't break if a known, ASN.1 value comes encapsulated
763 in an octet-string. The value will pass through unmodified in an Odr_oct.
765 Added a bit of code to the demo client to decode & display
766 ASN.1-structured records represented in the octet-aligned branch of
767 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
769 Added z_ext_getentbyref() to the ASN module. Doc updated.
771 * Completed the SCAN definition in the ASN module. This may break SCAN
772 code based on older YAZ-versions at compile-time. The fix is easy -
775 * Added 'displayTerm' and OtherInformation to the TermInfo structure
776 under the SCAN definition. Remember to initialize this, server-people.
778 Comstack should now support the WAIS protocol in TCP/IP mode. Note
779 that this does not extend to ODR and ASN.
781 Comstack allows insertion of established socket (primarily for
782 inetd-operation of servers). Doc updated.
784 Front-end server can now start from the inetd in TCP mode. Doc
791 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
792 the rank and record number.
794 Adjustments to the frontend server.
796 Fixed diagnostic BER dumper. It ignored the file argument.
800 Various changes to retrieval module.
802 Changed the union discriminators of the protocol files from enums to
803 ints paired with #defines.
805 *Changed oident.class to oident.oclass to avoid a reserved word in C++
808 *Changed operator in the RPN structure to 'roperator', again to avoid a
811 Fixed problems in Explain decoders/encoders.
815 Memory bug in log module fixed.
819 Occasional malloc() of 0 bytes fixed in d1_espec.c.
821 Bug in Explain DatabaseInfo module fixed.
823 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
827 The shift to v1.0 signals that we now consider the *core* functionality
828 of YAZ reasonably stable (the core being more or less equivalent to
829 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
830 tested (Explain not at all - though that will happen soonish).
832 Minor changes to code to support Windows port.
834 Various minor changes after we're getting to use GRS-1 & co. more.
836 Added Espec-1 format.
838 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
839 of the protocol and it cannot be selected when encoding (maps into 'string'
840 when decoding). Needed to talk to some servers.
842 Demo client can request simple element set names.
844 Added Diagnostic Format encoders/decoders.
846 Added simple Close handling to frontend server (no hooks for resource
847 reporting yet), and demonstration client.
849 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
853 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
854 handled incorrectly when records were requested in the searchResponse. This
855 will only affect you if you use the frontend-server.
857 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
858 Test-client will ask for and print GRS1. Ztest will return dummy records
861 Added Explain encoders/decoders to the service-level API. Untested.
863 Added Extended Services: Item Order encoders and decoders to the Service-
864 level API. Untested. We could use a recent copy of the pertinent bits
865 of the ILL protocol to add those bits.
867 Added diagnostic format 1 encoders/decoders to the service-level API.
870 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
871 odr_cons.c, which causes a more correct output.
873 Fixed handling of searchRequest in frontend server. NextResultSetPosition
874 was always set to 0 when no records were requested in the searchRequest.
876 * Added better external-handling. This shouldn't harm old code that
877 *encodes* externals. It can break code that looks for a
878 'single-ASN1-type' representation, since those types that are known
879 are now decoded immediately. Look at the SUTRS sample code in
880 seshigh.c and client.c. Documentation updated.
882 Handling of structured records in bend_fetchresponse. Length -1 marks
883 structured record, type is deduced from format field.
886 Fairly quick maintenance release to add SUTRS support.
888 Fixed handling of SUTRS records in the demonstration client.
890 * Added format field to the bend_fetchrequest and bend_fetchresponce
891 structures of the backend API (frontend server). When the record is
892 returned, the value of the format field is mapped to an OID. The
893 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
894 of the record. The special value VAL_NONE in the bend_request means
895 that no specific format was requested by the client. Documentation
896 updated accordingly. Test server (ztest) will return a fixed dummy
897 SUTRS record if your client requests SUTRS.
899 Documentation updated accordingly.
901 You can now set external libraries and RANLIB support in the top-level
905 First public release.
