1 Added support for CCL, compiled on the client side, in ZOOM-C. This
2 is invoked using ZOOM_query_ccl2rpn(); the resulting query objects can
3 be used for for searching with ZOOM_connection_search() and scanning
4 with ZOOM_connection_scan1(). Before it can be used for CCL
5 searching and scanning, the connection object must be configured by
6 setting the "cclfile" option to the name of a CCL qualifier file such
7 as the one in "client/default.bib".
9 YAZ' configure searches for OpenSSL by default.
11 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
12 SL_CTX_use_certificate_file. See
13 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
14 for more info. Thanks to Ko van der Sloot.
18 Bug #600: SRU GET, POST support for yaz-client. Introduced
19 command 'sru' which selects method SOAP/GET/POST.
21 Allow missingValueAction to be specified for the sortspec string -
22 function yaz_sort_spec. By default, the missing value action is null.
23 Use ! to specify "abort". Use = followed by stringvalue to specify default
26 Ensured that Present-handler (if defined) is called in GFS before any call to
27 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
28 searchRetrieve requests.
30 Documentation for YAZ is now based on the Docbook XML/XSLT using
31 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
32 is no longer depending on jade/openjade or docbook-to-man scripts.
33 PDF is no longer part of the distribution - but can optionally be
34 made using DSSSL/jadetex or FOP.
36 Added retrieval handling support in Generic Frontend Server to support
37 conversion between MARC/XML as well as XSLTtransforms. See
38 etc/yazgfs.xml for an example.
40 Added Authentication support to Generic Frontend Server in SRU
41 mode. Authentication using HTTP Basic is supported, as is the use
42 of 'x-username' and 'x-password' parameters in the request itself.
44 Added support for a new character set MARC8s identical to MARC8 except
45 that it converts combined characters to single Unicode characters in the
46 Latin-1 range (when possible).
50 ASN.1 compiler 0.4: generates brief Doxygen file header for
51 generated .h/.c files.
53 Utility yaz_iconv now supports conversion to MARC-8.
55 New facilities for the MARC module. The reading - and writing of
56 content are separate methods for the yaz_marc_t handle. The following
57 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
58 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
59 format). Write functions have prefix yaz_marc_write_.. The existing
60 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
61 available. Removed support for OAI-MARC and simplexml (not the
64 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
65 to be returned for this connection.
69 Allow multiple languages and charsets to be specified with
70 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
71 negcharset iso-8859-1,utf-8
73 Translation of proximity nodes from CQL into PQF now works.
75 Moved to automake 1.8, 1.9.
77 Added function yaz_log_set_handler which allows a log handler to be
78 installed. This handler will be called for all log messages. Output
79 to file is also produced; but that can be disabled by passing NULL
80 fname to yaz_log_init_file.
82 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
84 For SRW (including GFS), accept application/soap+xml as content-type
87 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
88 produces NO stylesheet reference even if a default stylesheet is specified
93 Updated Windows package to include yazd.dll + yazd.lib for the
94 Development component.
96 If the environment variable YAZ_LOG is set, then it is used as a
97 string indicating the default level of logging to use if not
98 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
99 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
100 used as before. So, for example, to omit warnings from YAZ logging,
103 cql_transform() now map structure and other attributes before indexes,
104 so that index-specific structures and other attributes can override
105 defaults. So now a combination of mapping specifications such as:
107 index.dc.date = 1=date-modified 4=5
108 does the right thing.
110 cql_transform() now also respects the "always" mapping specification,
111 which establishes an initial set of attributes to be used for all
112 terms except where overridden by more specific attributes associated
113 with the index, relation or modifier.
115 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
116 which mode to use; one of "post", "get" or "soap" (SRW, default).
118 Fixes for yaz_iconv routines: changed trie-based character set conversions
119 to use only non-negative values for bit fields due to Sun's C compiler not
120 supporting negative values.
122 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
123 sequences where not read correctly. Fix by Rustam Usmanov.
125 Updated win/makefile to use options, settings which makes things
126 compile with VS C 2005.
128 --- 2.1.12 2006/02/01
130 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
132 In ZOOM socket code, use select instead of poll on MacOSX.
134 ZOOM-C now support client-side compilation of CQL into RPN that is
135 sent to the server, enabling CQL to be used against all Z39.50
136 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
137 ZOOM_query object, and submit it using ZOOM_connection_search().
138 The CQL-to-RPN translation uses a configuration file, the name of
139 which must be specified in the Connection's "cqlfile" option.
141 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
142 function, which takes as its start-term parameter a ZOOM_query object
143 (which may have had either CQL or RPN set into it).
146 --- 2.1.10 2005/11/29
148 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
149 GFS to support this as well. Backend handler, bend_srw_update, does the
150 update work. Code contributed by Ko van der Sloot.
152 Allow retrieval of Search Result-1 information in ZOOM by the use of
153 options that are attached to a result set. ZOOM documentation updated
156 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
157 UTF-8 conversion. Patch by Raj Patel.
159 Added option -m to GFS to control formatting of timestamps in log file.
161 Added 'exit' as synonym for 'quit' in yaz-client
163 Added support for specifying SRW resultSetId + resultSetIdleTime in a
164 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
165 for the new members. Patch by Ko van der Sloot.
167 Added support for SRU POST. It is supported for content-type
168 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
170 Do not build the separate Multi-threaded (MT) library libyazthread.la.
171 Instead make the library libyaz.la multi-threaded. Threading as a whole
172 can still be disabled by configure option --disable-threads. Previosly,
173 with older GLIBCs there were problems with MT libs under Apache. This
174 has now been fixed a long time ago.
176 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
179 CQL module modified to be case insensitive for relations/indexes/operations.
181 Fixed bug in CQL transform code: incorrect value relationModifieder
184 Added 'show all' command for yaz-client which retrieves all results
187 Added new yaz-client, xmles, which takes a (private) OID and
188 a document to be sent as an extended service request.
190 Describe new yaz-client commands wait_response and set_auto_wait.
192 Increase TCP/IP listener backlog from 3 (which I am guessing was
193 copied from the SunOS manual entry way back when) so SOMAXCONN, so
194 that the socket will queue as many incoming connections as it's able
195 to handle ongoing connections. In other words, it will never now
196 refuse a connection that it would be able to handle merely because
197 it's not got around to accepting() enough of the pending connections
198 yet. This is the behaviour anyway under Linux, where the listen()
199 argument is ignored; but not under BSD and on systems such as
200 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
201 YAZ-based servers should now be uniform across operating systems in
204 yaz-marcdump uses 64-bit file access on some systems. This is enabled
205 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
206 This allows yaz-marcdump to read large MARC batches (>2 GB).
208 Modified all YAZ source files - except the source which is auto-generated
209 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
212 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
213 corresponding to the existing *_setl() function. These allow option
214 values containing arbitrary valuues.
216 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
217 ZOOM_resultset_sort() in new applications. Its behaviour is identical
218 except that it returns an indicator of whether or not the sort
219 criterion was accepted (0 for OK, -1 for invalid).
223 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
224 MARC output rather than returning "new" buffer.
226 yaz-client warns about unknown init options.
228 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
232 Added support for SRW sort in Generic Frontend Server. Patch
233 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
234 sortKeys - or NULL if none is provided.
236 Fixed bug #307: It was impossible to specify indefinite/no timeout
237 for ZOOM_event. Special timeout value -1 now means indefinite timeout
240 Added support for multiple languages and charsets to be specified in
241 ZOOM. Each charset/language is separated by a blank. If negotiation is
242 in effect in init-response, Option
243 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
244 Code based on patch by Vasiliy Osadchuk.
246 Fixed bug #306: infinite recursion that occurred when calling
247 yaz_log_level_init as the first call (before other log level or
250 Fixed bug in scan handling in front end server: if preferred-Position-In-
251 Response was non-present, a NULL pointer referece was performed.
255 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
256 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
257 now defined for all those error codes. So instead of putting 109 in
258 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
259 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
261 Modified the yaz-marcdump utility to skip garbage bytes between MARC
264 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
266 Program yaz-client now exits and produces an error message if multiple
267 Z39.50 servers are specified on the command line (none or one allowed
270 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
275 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
277 Fixed bug #272: Preserve spacing for CCL terms.
281 Added support for virtual hosts and multiple backend servers for
282 the YAZ frontend server. The configution is XML based and
283 support specificition of CQL to RPN mappings and explain information.
284 See section "Virtual Hosts" in the YAZ manual.
286 Extended OPAC display utility. OPAC display utility renders
287 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
288 to supplement yaz_marc_decode_wrbuf.
290 Fixed a bug in MARC decoder that could caused it to crash for some
291 invalid MARC records. More diagnostics and warnings where added in
292 XML output (warnings, etc are stored in comments).
294 --- 2.0.34 2005/02/08
296 Fixes for UNIX domain sockets. Bug #261.
298 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
300 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
301 Added yaz_marc_subfield_str which defines subfield lead string which is
302 used in YAZ_MARC_LINE format. Default string is blank+$. Added
303 yaz_marc_endline_str which defines end of fields string used in
304 YAZ_MARC_LINE format. Default string is newline.
306 Experimental support for MarcXChange. This format can be produced
307 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
308 http://www.bs.dk/standards/MarcXchange.xsd
310 Added yaz-client commands scansize that sets maximum number of
311 entries to be returned by scan.
313 --- 2.0.32 2005/01/11
315 Added support for SRW scan in yaz-client and Generic Frontend Server.
317 * Added whereInList member to SRW Scan Term.
319 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
321 Fixed NMEM system to return aligned blocks on the smallest boundaries
322 that are suitably aligned for all possible types on the particular
323 architecture YAZ is being built for.
325 --- 2.0.30 2005/01/04
327 Fixed numerious warnings that was issued with newer versions of GCC.
329 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
330 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
333 Make YAZ Generic Frontend Server slightly faster.
335 Enhance (and reduce) logging for Generic Frontend Server.
337 Revert YAZ log system so that it flushes every write operation
338 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
340 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
341 instead of LOG_, due to name clash with syslog(3). LOG_ are still
342 present. New applications should define YAZ_USE_NEW_LOG=1 - this
343 will effectively disable old definitions.
345 --- 2.0.28 2004/11/09
347 Added yaz_log_time_format which specifies log format using
350 Added yaz_log_module_level which returns mask for a module. Value
351 is non-zero mask a if module is enabled; zero if disabled.
353 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
354 in include/yaz/cql.h.
356 Fixed bug #176: Dont throw diagnostics on empty SRU args.
358 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
360 Fixed bug #172: RPM builds does not enable SSL.
362 Doxyfile.in part of dist. Doxyfile generated by configure.
364 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
365 are given and the corresponding component does not exist.
367 Extend CCL documentation in YAZ reference. Describe r=r.
369 --- 2.0.26 2004/10/01
371 Fixed MARC->MARCXML conversion to properly deal with
372 fields, subfields, indicators having non-ASCII characters.
374 Fixed MARC->MARCXML conversion so that ASCII control characters
375 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
378 Added YAZ GFS support for conversion from Z39.50 surrogate
379 diagnostics to SRW surrogate diagnostics.
381 Bug fix: YAZ GFS did not return schema in explainResponse.
383 --- 2.0.25 2004/09/30
385 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
386 now converts recordSchema to elementSetName as well as schema URI.
388 Fixed bug in COMSTACK that prevented HTTP request packages from being
391 --- 2.0.24 2004/09/29
393 Added CCL facility r=r "range" which is similar to r=o "ordered" but
394 does not require white-space before and after the dash in a range, e.g.
395 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
398 Fixed a few AC_TRY_LINK configure tests that did not operate properly
399 due to new GCC removing "redundant" code.
401 Added yaz-client commands scanpos and scanstep that sets preferred
402 position and step-size for scan.
404 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
406 Added CCL utility ccl_qual_buf which parses one or more CCL
407 spec lines in a buffer.
409 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
410 of name and value - ignoring empty lines and comments.
412 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
414 Added odr_get_element_path which returns current element path for an
415 ODR handle. This utility is useful in error handling or user-defined
418 Added ODR_PRINT utility odr_set_stream which is is a more generic
419 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
420 to a write function and pointer to close function. The close function - if
421 non-NULL - will be called during odr_destroy.
423 Fixed bug in CCL parser where truncation char was not removed from
424 right side when truncation=both was in effect.
426 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
429 --- 2.0.23 2004/08/11
431 Fix buffer overrun in CQL parser when dealing with proximity (%).
433 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
434 to UTF-8/UCS conversion is now only based on codetables.xml.
436 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
438 --- 2.0.22 2004/08/06
440 Add support for more "commit changes" in ZOOM (uses Extended Services).
442 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
445 Yet another small fix for configure of SSL.
447 --- 2.0.21 2004/05/14
449 Fix SSL libs for configure when --with-openssl=DIR is given.
451 --- 2.0.20 2004/05/10
453 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
455 SSL comstack now uses yaz.pem certificate file on server side
456 by default. Certificate filename can be configured by calling
457 comstack function cs_set_ssl_certificate_file before cs_bind is used.
459 Fix bug regarding multiple calls to ZOOM_connection_connect.
461 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
463 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
464 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
466 ZOOM now allows inspection of X509 peer certificate for verification.
467 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
469 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
470 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
471 as "modular" but it simplifies things.
473 Added cs_get_peer_certificate to that returns peer X509 PEM.
475 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
476 NULL if SSL is unavailable.
478 Documentation about MARC decoding tools.
480 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
482 --- 2.0.19 2004/03/30
484 Rename CHANGELOG to NEWS to follow GNU style packing.
486 Fix bug with missing initialization of member in init_diagnostics.
487 This bug affects threaded version of GFS server.
489 --- 2.0.18 2004/03/20
491 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
494 Ensure zlib.dll is packed with Windows install.
496 --- 2.0.17 2004/03/17
498 Fix encoding of xsd:string to use text instead of CDATA.
500 Fix endless loop in CQL parser with unbalanced ".
502 Use a more compact way to store MARC-8 conversion tables.
504 --- 2.0.16 2004/03/16 Debian only
506 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
509 Update CQL parser to use new CQL 1.1 modifiers for booleans and
514 --- 2.0.15 2004/03/01
516 Another fix for decoding of XML packed records.
518 --- 2.0.14 2004/02/25
520 Fixes for Chunked encoding. White space not ignored after length spec.
522 Update NS and use default NS for SRW diagnostic elements.
524 --- 2.0.13 2004/02/23
526 Implement ZOOM_resultset_cache_reset which resets record cache.
528 Implement ZOOM_resultset_sort which sorts a result set.
530 Implement chunked HTTP transfer.
532 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
534 --- 2.0.12 2004/02/16
536 Added member 'schema' to bend_explain_rr structure so that backend
537 can specify explain record identifier. Defaults to Zeerex 2.0.
539 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
541 --- 2.0.11 2004/02/16
543 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
546 Added init command for yaz-client which sends "extra" init request.
548 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
549 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
551 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
553 Make ZOOM error code for "invalid query".
555 Fixed compilation for SSL which wasn't properly enabled for all platforms.
557 --- 2.0.10 2004/02/05
559 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
562 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
564 Added option -p <file> to make Generic Frontend Server to write PID file.
566 Added option -D to put Generic Frontend Server in background on its own.
568 Make ZOOM C recognize option "password". If unset, "pass" is used
569 (for backwards compatibility).
571 Fixed a bug in Generic Frontend Server that could make it crash if a
572 client sets characterSetNegotation bit, but didn't pass negotiation stuff
575 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
576 Must be issued before open, in order to be in effect.
578 --- 2.0.9-6 2004/01/12 Debian/Windows
580 Make the SRU server more picky WRT unknown params, etc.
582 Bug fix: ZOOM scan response didn't return displayTerm - when present.
584 New YAZ client command, options, that sets Z39.50 options.
586 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
587 options from a string of tokens (one token for each option bit).
589 Update SRW diagnostic code messages.
591 --- 2.0.9-5 2004/01/07 Debian/Windows
593 Handle user defined stylesheet for SRW/SRU.
595 --- 2.0.9-4 2004/01/06 Debian/Windows
597 Fix bug in decoding of Content-Length.
599 --- 2.0.9-3 2004/01/06 Debian/Windows
601 Fix a bug with decoding of XML packed records.
603 --- 2.0.9-2 2004/01/05 Debian only
605 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
607 Fix bug in SRW/SRU diagnostics decoding.
611 Fixed bug in Generic Frontend Server which could drop records exceeding
612 preferred message size. Reported and fixed by Irina Dijour.
614 Fixed calculation of package size for structured records in Generic
615 Frontend Server. Reported and fixed by Irina Dijour.
617 Fixed namespace for SRW/SRU diagnostics.
619 Fixed SEGV in yaz-client that occured for HTTP connection errors.
623 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
624 this version is incompatible with version 1.0 and older YAZ SRW/SRU
627 CQL changes to reflect recent changes to the specification:
628 * Documentation talks about context sets instead of index sets.
629 * Documentation talks about indexes instead of qualifiers.
630 * The CQL-to-PQF transformer's configuration file now uses
631 "index.set.name = <attributes>" instead of the old form
632 "qualifier.set.name = <attributes>". (Both forms are still
633 understood but the latter is deprecated.)
634 * CQL terms with no explicit index specified are now interpreted as
635 cql.serverChoice instead of srw.serverChoice (which of course
636 behaves exactly the same.)
640 MARC conversion can now generate ISO2709 output in another
641 character set. yaz-marcdump uses this facility if you invoke it
644 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
645 functions from there can be used from C++.
649 Frontend server now transfers memory from decoded packages to stream
652 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
653 references to show up.
655 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
656 the ZOOM Abstract API. The older names for the same options are still
657 also supported for the benefit of old applications.
659 ZOOM-C supports "implementationId" and "implementationVersion" options
660 to go along with "implementationName". These allow the user code to
661 specify identification strings to be sent to servers.
662 Add OID for the new ExtLite attribute set.
664 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
665 as requested/supplid by Ere Maijala <ere@atp.fi>
667 For generic frontend server, reverse the order of
668 "toolkit-supplied / application-supplied" strings sent as implementationId,
669 Name and Version. Also, remove the spaces around the slash. This brings
670 the GFS in line with the behaviour of ZOOM-C on the client side.
672 Add function ZOOM_scanset_display_term.
674 yaz-client shows scan displayTerm if present.
676 Utility yaz-iconv is now installed by default along with the man page
679 Extend configure check for OpenSSL to use pkg-config where available (such
682 Incorporate patch by Morten Bogeskov which allows a Unix file socket
683 server to specify uid/gid/mask for socket using the format
684 unix:[user=uid,][group=gid,][umask=mask,]file=path
685 If file= is omitted the existing format is assumed, e.g.
687 in which case the mask is 0666 (rw for everybody).
689 Major restructure of YAZ source. All source in libyaz is in src directory.
690 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
691 util (utility programs such as ASN.1 compiler, yaz-marcdump).
693 Added man page for utility yaz-marcdump (used to be called marcdump).
694 yaz-marcdump is installed by 'make install'.
696 Fixed a memory leak in Generic Frontend Server that occurred when decoding
697 of incoming package failed.
699 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
701 Change prototype of odr_perror: add const to message string.
703 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
705 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
706 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
707 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
708 DNS lookup. There should not be any compatibility problems with this
709 assuming that blocking=1 or 0 is used.
711 Fix bad reference in UNIX comstack in function cs_addrstr.
713 Fix for compilation on AIX.
715 The generic front-end server (server/seshigh.c) now supports returning
716 Init diagnostics to the client in User-information-field, in
717 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
722 Allow any CQL relation (not just all,any,exact,scr).
724 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
725 that features the same UI.
727 Implemented command update0 in YAZ client which is equivalent to
728 update but uses old of Ext Update ASN.1.
730 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
731 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
732 Previously no OID was used for this info.
734 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
735 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
736 returns 'malformed search term' otherwise.
738 SortResponse member resultCount now set to NULL in sort handler of
741 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
744 Add three new utility functions for translating OIDs between various
745 formats -- symbolic name such as "Usmarc", minus-1-terminated int
746 arrays and dotted strings such as "1.2.840.10003.9.5.1":
747 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
748 char *oid_to_dotstring(const int *oid, char *oidbuf);
749 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
751 Reverted modifications for ES Update definition for z_IU0Update
752 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
753 is back to YAZ 2.0.2.
755 String value attributes for CCL parser.
757 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
758 which their FirstSearch server returns in Init responses, sometimes
759 carrying useful diagnostic information when Init fails. This has the
760 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
761 "z39.50/oclcui.asn", where its definition is somewhat different from
762 what OCLC document on their web-site, as required to interoperate with
765 Support for anonymous authentication in yaz-client. Use the command
768 * Fix the OID of the Index Data-local "admin" Extended Service from
769 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
770 the 1000, which indicates a locally-defined OID, was a mistake.
774 Fix CCL directive @case handling so that it affects string match for
775 both CCL keywords and qualifiers.
777 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
778 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
779 Decoder has been updated with ASN.1 changes as listed in
780 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
781 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
782 z_IUUpdate, remains unchanged.
784 ZOOM_record_get may now return a record in a specific character set.
785 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
786 "from" is the character set of record as returned by target. "to" is
787 the character set to be returned. If omitted, "to" is UTF-8.
789 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
791 New ODR utility, odr_getelement, which returns name of element for
792 which encoding/decoding failed.
794 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
795 in cases where a required element was omitted.
797 Bug fix: some MARC8 sequences were not converted.
799 New ZOOM option "step" which specifies number of records to be
800 retrieved in one chunk. Used in conjunction with "start" and "count".
802 SRW support for yaz-client. Use scheme http: to use it, e.g.
805 yaz-client no longer does (un)intelligent character set conversions
806 by default. Can be enabled with charset and marc_charset commands.
808 xmalloc trace fix for 64-bit systems such as DEC alpha.
810 Solaris 2.6 compile fix.
812 New function, cql_strerror() translates SRW error codes, as returned
813 by cql_transform_error(), into human-readable English strings. Used
814 in yaz-client diagnostics when appropriate.
816 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
817 converts it into a type-1 query which is sent to the server. This
818 makes CQL available for use with all Z-servers, as opposed to the tiny
819 minority that can handle CQL queries themselves.
823 New Debian package layout similar to the Redhat Package layout.
825 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
826 and search result respectively.
830 Redhat package is now several packages: libyaz (runtime libraries),
831 libyaz-devel (development and documentation, and yaz (utility programs).
832 Package spec file by Morten Bøgeskov.
834 New member 'schema' in struct bend_fetch_rr which the name of requested
835 schema (SRW/SRU) for record (or NULL if none was given). The fetch
836 handler MAY set this to reflect the schema of the returned record.
838 New member 'display_term' in struct scan_entry. GFS now sets member entries
839 and allocates scan entries to be filled by user scan handler. In previous
840 version, entries member was allocated by the scan handler. That still works,
841 but the GFS will ignore member display_term - assuming it was NOT set by
842 the handler. The fact that the GFS now allocates the entries both allows
843 for new members and makes a scan handler easier to write.
845 Fix CQL lex buffer overflow.
847 SRW/SRU recordPacking. For SRW default recordPacking is string. For
848 SRU default recordPacking is string.
850 SRU protocol support for frontend server.
852 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
854 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
856 Added scan for the ZOOM shell (zoomsh).
860 * String Identifers for Schemas (Amendment 5).
861 http://lcweb.loc.gov/z3950/agency/amend/am5.html
862 Old definition for schema
863 Odr_oid *schema; /* OPT */
868 Z_InternationalString *uri;
869 #define Z_Schema_oid 1
870 #define Z_Schema_uri 2
873 * resultCount parameter to Sort Response (Amendment 1).
874 http://lcweb.loc.gov/z3950/agency/amend/am1.html
876 Support for SRW 1.0 over HTTP. This is an optional feature and
877 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
880 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
881 on the same port. SRW SearchRetrieveRequests are mapped
882 to bend_init,bend_search,bend_fetch,bend_close.
884 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
886 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
887 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
889 ZOOM connections are SRW based if schem http is used for hostname
890 in connect, e.g. z = ZOOM_connection_new("http://myserver");
891 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
893 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
894 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
895 distance=n, order=true/false, relation=le, prox unit=word. If
896 n is omitted, distance 1 is used.
898 Fixed problem with C compiler include path in wrong order.
900 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
901 on Solaris. Patch from Ko van der Sloot.
903 New MARC decode API. All new functions operate on a yaz_marc_t
904 handle. The most important new functions are: yaz_marc_create,
905 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
906 decode and destroy respectively. Decoder can produce formats
907 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
908 include/yaz/marcdisp.h.
910 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
911 to UTF-8, UCS-32, wchar_t or Latin-1.
913 * Prototypes for yaz_iconv_-functions moved to separate header
914 include/yaz/yaz-iconv.h.
916 Make a few private functions 'static' in unix.c. This prevents
917 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
919 For ZOOM connection, the options targetImplementation{Id,Name,Version}
920 are set when Init Response is received.
922 New function ZOOM_connection_error_x similar to ZOOM_connection_error
923 but returns diagnostic set as well.
925 New function yaz_strerror which is a portable wrapper for
926 strerror/strerror_r/GetLastMessage.
928 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
929 is returned for MARC. If type is "oai", then OAI MARC is returned.
931 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
936 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
938 Fix bad race conditions on SIGTERM and terminate gracefully in
941 Move retrieval (data1) module to Zebra since nobody seems to be
944 Add GRS-1 render for ZOOM using same format as yaz-client.
948 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
950 Fix broken ESpec handling in data1 module.
952 SGML reader parses comments and makes them part of the data1 tree.
954 Added several type casts so that YAZ compiles as C++ code.
956 ZOOM didn't handle PDU encoding failures properly.
958 Added more Bib-1 diagnostics (approved extensions).
960 GNU configure: better check for iconv.
962 More portable use of accept, getpeername. Check for socklen_t. Use
963 int/size_t if socklen_t is not defined.
967 PQF parser rejects bad queries - including those with extra
968 characters in them. PQF parser used to silently ignore that.
969 Cleaner API for PQF added, which allows you to get detailed
970 error information for bad queries (see yaz/pquery.h).
972 Fixed bug in ZOOM_record_get for type "database".
974 Implemented mini iconv library supporting conversions between
975 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
977 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
981 Fixed ZOOM C record cache so that preferredRecordSyntax and
982 elementSetName is used to check for already fetched records.
986 Added three members in bend_initrequest structure to facilitate
987 character set negotiation.
989 Fixed a bug in frontend server that could cause indefinite
990 loops under rare conditions.
992 Revised character set utilities (charneg.h) so that encoding
993 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
995 For PQF, directive @term <type> sets term type for Scan/Search.
996 Here <type> is general, string, numeric, null. The term type
997 is inherited - just like @attr.
999 New call odr_set_charset that sets character set conversion for
1000 international-strings on a ODR stream. Prototype is:
1001 int odr_set_charset(ODR o, const char *to, const char *from);
1002 The InternationalString is still represented as C string in YAZ
1003 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1004 won't). On the protocol level, you can use any encoding.
1006 Support for UNIX sockets in ZOOM.
1008 Solaris recv sometimes returns errno == ENOENT. It is treated as
1009 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1011 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1012 both client and server. Code by Morten Bøgeskov.
1014 --- 1.8.7 2002/05/22
1016 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1017 that they can be used directly from Visual Basic. You must recompile
1018 your windows APP if you're using ZOOM.
1020 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1021 Commands "lang" and "charset" sets language and character set respectively.
1022 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1023 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1025 Attributes from multiple CCL fields may be OR'ed rather than merged
1026 using directive "@field or". Fields are still merged by default -
1027 equivalent to "@field merge".
1029 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1032 Fixed bug in zget for parameter ExtendedServicesResponse.
1036 --- 1.8.6 2002/03/25
1038 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1040 Client displays USR.1:SearchResult-1 (hits per term).
1042 Additional Search Info for search in Generic Frontend Server.
1044 Fixed CCL parsing of "field=s".
1046 WIN32 installer - using the excellent NSIS software from nullsoft.
1048 Fixed CCL parsing of "field = - <number>".
1050 Added function yaz_marc_decode that decodes MARC for line mode
1051 display or XML (similar to that used by JZKit).
1053 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1054 Z39.50. But ISO/ILL was, however.
1056 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1057 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1059 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1060 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1062 --- 1.8.5 2002/02/03
1064 New YAZ client features: Command completion and new commands:
1065 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1066 Code provided by Jacob Poulsen.
1068 New call oid_trav, that visits all registered OIDs via callback.
1070 Function ZOOM_record_get now returns const char pointer rather than
1071 void pointer. It saves a lot of type casts.
1073 For YAZ client, command "auth" now allows you to set authentication
1074 in IdPass style. It is enabled when three tokens are given - order
1075 is user, group and password.
1077 Fix memory leaks in MARC record handling for ZOOM.
1079 New option for YAZ client, -k <kilobytes> that sets
1080 maximum record size. Similar to -k option for generic frontend
1081 server and yaz-ztest.
1083 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1085 Prefix query parser reports "fail" when bad attribute set is given.
1087 Fix in MARC decoder. Proximity logging. Fix for attribute set
1088 in scan handler for server. Patches by Shigeru Ishida.
1090 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1093 Configure option --with-openssl=<dir> now works when a directory is
1094 specified. Patch provided by Morten Bøgeskov.
1096 New option for YAZ client, -u <auth>, that sets authentication.
1098 ZOOM fix: error information was sometimes "missing", since error
1099 was cleared/reset too when it shouldn't.
1101 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1103 --- 1.8.4 2002/01/04
1105 Scan for ZOOM API. New object ZOOM_scanset. New functions
1106 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1107 ZOOM_scanset_destroy.
1109 New ZOOM function, ZOOM_connection_last_event, that returns type
1110 of last event (such as "receive data", "send data", "apdu received",
1113 New ZOOM option, schema, that specifies schema for retrieval.
1115 New CCL feature. Qualifiers can be aliases for one or more
1116 other qualifiers (if more than one is given, OR is used).
1118 ZOOM uses named result sets if target supports it.
1120 Two new YAZ client commands: . (dot, which sources a script of YAZ
1121 client commands), and ! (to execute shell command.). Implemented
1124 Working on Debian packages.
1126 --- 1.8.3 2001/11/19
1128 YAZ client enables named result sets only if target supports it.
1130 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1132 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1133 with key="host" to get same result.
1135 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1136 Function Z3950_resultset_record(s) returns references to records
1137 "owned" by resultset. To become owner use Z3950_record_clone.
1139 Function z_ext_record handles Extended Services. Thanks to
1142 --- 1.8.2 2001/11/12
1144 CCL Parser fix: ignore token comma when dealing with and-lists.
1146 Documentation updates for COMSTACK.
1148 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1149 Changed prototype Z3950_records. For some functions, int parameters
1150 were changed to size_t.
1152 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1155 New MARC decode/display function, marc_display_exl, which properly rejects
1156 non-ISO2709 records. YAZ client uses it.
1158 --- 1.8.1 2001/10/29
1160 Fix bug: local attribute set wasn't set correctly in PQF strings.
1164 * Old Z39.50 codecs no longer supported.
1166 Added ZOOM C binding. See http://zoom.z3950.org/
1168 Renamed states for COMSTACKs to avoid confusion with events.
1170 Implemented cs_look and proper cs_rcvconnect.
1172 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1174 Configure detects POSIX threads on OpenBSD.
1176 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1177 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1179 When error is returned from present handler, non-surrogate diagnostic
1180 is returned in present response (and fetch handler is no longer called).
1182 * Minor adjustments to pquery parser (PQF). Token characters may be
1183 escaped by using backslash (C-style).
1185 PQF parser allows string attribute values to be specified. For @attr,
1186 non-numeric characters after the equal-sign are treated as strings
1187 (e.g. @attr 9=title).
1189 CCL trunction character may be defined (@truncation in file)
1191 * function zget_ExtendedServicesRequest sets waitAction to
1192 waitIfPossible (was wait).
1194 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1197 CCL operator names may be set in field definition files (CCL_bibset).
1198 See ccl/bib1 for an example.
1200 Fixes in ASN.1 compiler for C++ compatibility.
1202 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1203 and "op_or" to avoid conflict with C++.
1205 Fixed problem with GNU readline detection on Redhat 7.0.
1207 Added step-size for Scan backend handler.
1209 Fixed bug that made the frontend server crash when no attribute
1210 set was specified for scan.
1212 Front-end server automatically switches to original working directory
1213 when installed as an NT service. Previously -w had to be specified to
1216 Added extended attributes for retrieval module (data1), so that data1
1217 records carry d1_readXML/SGML attributes. d1_read also supports
1218 null-data rules ( <tag/>)
1220 On UNIX when POSIX threads are available, a separate library libyazthread
1221 is created. Programmers should link with that library and the yaz library
1222 when using threads. The reason for the split was that some applications
1223 on Linux, such as Apache, doesn't work well when using shared objects that
1226 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1227 (or any frontend server) in SSL mode by specifying ssl: followed by
1228 address. Only tested on UNIX.
1230 Added feature for CCL module. Virtual structure s=al or s=ol generates
1231 and-list and or-list respectively instead of phrase search.
1235 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1236 log_mask_str. This was done to avoid name conflicts with other libraries
1237 (such as other PHP extensions).
1239 Added raw OID member for preferred record syntax (request_format_raw)
1240 and returned record syntax (output_format_raw) for backend fetch method.
1242 Config file yaz-config now accepts options so that it returns specific
1243 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1245 Shared library support for UNIX using GNU libtool.
1247 * Modified backend interface. Request/Response struct's replaced by
1248 one read/write C struct. For example bend_fetchrequest and
1249 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1250 Every handler - even search has to be registered in bend_init
1251 handler. This means that the YAZ library no longer refers to
1252 external functions and it makes it possible to make the whole
1253 thing a single DLL/SO.
1255 Added Segment handler for backend server.
1257 Added Zmbol/Zebra administrative functions to YAZ client.
1259 Threaded frontend server on UNIX (when POSIX Threads are available).
1260 Starting the server with option -T enables multi-threading.
1264 Added configure option --enable-comp/disable-comp to control use
1265 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1266 located in sub directory asn.
1268 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1269 in ${exec_prefix}/bin along with the other programs yaz-client and
1272 GNU automake used to maintain makefiles.
1274 Added several OID's.
1276 Changed retrieval module so that we can load records with no abstract
1277 syntax defined. Tagpaths in these records are fully composed of string
1280 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1284 On UNIX, the generated makefile now supports a proper 'make install'.
1285 The prefix can be set via GNU configure to set the install location
1286 (default is /usr/local).
1288 * YAZ programs client and ztest were renamed to yaz-client and
1289 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1290 locations, such as /usr/bin,/usr/local/bin,etc.
1292 * YAZ Header files were moved from include to include/yaz. YAZ Header
1293 files are referred to as include <yaz/log.h> rather than <log.h>.
1294 The YAZ include path (-I ..) is therefore the same as before. Programmers
1295 should update their #include statements or use -Ipath/include/yaz
1296 instead. The main motivation for doing this change is that YAZ header files
1297 can be installed in "standard" locations /usr/include,/usr/local/include
1298 without introducing conflicts, since ALL YAZ header files are stored
1299 in subdirectory yaz (under /usr/include for example).
1301 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1302 rather than project/workspace files. We switched because project files
1303 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1306 Changed name of logging function, logf, to yaz_log, to prevent name
1307 clash with some math-log functions. The YAZ header log.h defines logf
1308 to yaz_log (#define) so there should be no incompatibilities by this
1311 Added bend_start/bend_stop handlers for server. These handler are
1312 called on start/stop of server. For windows they are called whenever
1313 a service is started/stopped.
1315 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1316 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1317 in util/yc.tcl. The auto-generated C code structures are, in a few
1318 cases, incompatible with the old decoders. There are differences in the
1319 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1320 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1321 The preprocessor variable ASN_COMPILED is defined when the compiled
1322 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1323 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1324 wish to use the old encoders/decoders you can specify --disable-yc
1327 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1328 version so that it supports both new - and old version of DB Update
1330 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1331 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1332 change. The name parameter can be set to 0 in which no name is specified
1333 for the construction. The macros odr_implicit and odr_explicit sets name
1334 parameter to zero for the construction involved. New macros
1335 odr_implicit_tag and odr_explicit_tag are similar to the others,
1336 except that a name parameter is added. For programmers' that don't use
1337 ODR they probably only need to change the call to z_APDU and z_External.
1339 Added access control facility by interfacing the TCP wrapper library.
1340 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1341 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1342 name of the daemon and enables the access control as specified in
1343 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1345 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1346 den Dool <H.M.vdnDool@kub.nl>.
1348 Added reference ID parameter to most functions in server API - refer
1349 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1351 Changed name of ccl library to libccl.a (was ccl.a).
1353 Fixed bug in decoder for Explain (Category TargetInfo).
1355 Added support for GNU readline in client. Thanks to Jacob Poulsen
1356 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1358 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1359 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1360 IMPLEMENTATION! This change was made to the development version before
1361 the ZIG decided to retract the amendment. If any users MUST be
1362 compatible with the original Update definition, PLEASE CONTACT US, and
1363 we will include a separate definition corresponding to the old Update
1364 ES. Note that because of the change to the ASN.1 of the
1365 TaskPackageRecordStructure we cannot define a single structure that
1366 will support both versions.
1368 * Added const modifier to buffer parameter for some ODR/BER encoding
1369 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1370 completeWAIS, odr_dumpBER.
1372 Fixed bug in client.c which caused a crash when a scanResponse didn't
1373 contain positionOfTerm.
1375 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1376 * will cause an error in a client if a non-YAZ target sends both a
1377 * list of Scan entries and non-surrogate diagnostics.
1379 Retrieval module enhancements. Tag sets may be typed in the reference
1380 to it. From the .abs-file the "tagset" directive takes a third optional
1381 integer type for the tag set referenced. From a .tag-file the "include"
1382 directive takes a third optional type as well. The old "type" directive
1383 in the tag set itself is still recognized but acts as the default type
1386 Backend interface change. Individual Scan terms returned from bend_scan
1387 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1388 in include/backend.h.
1390 Retrieval module enhancements. Multiple tag sets and attribute sets may
1391 be specified in abstract syntax specs. Revised the error/warning for
1392 logging messages reported by the retrieval module when reading the
1395 Object Identifier system (oid_..) changed. The API is backwards
1396 compatible but the oid-routines now allocates new OID's when needed.
1397 Raw OID's may be specified in oid_getvalbyname.
1399 YAZ now uses GNU configure to generate Makefile(s).
1401 * Minor changes in some of the member names of DeleteResultSetRequest and
1402 DeleteResultSetResponse. See include/proto.h.
1404 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1405 and added member 'languages' in TargetInfo (which was missing).
1407 Changed the way attribute sets are handled in the retrieval
1408 module. These are now cached, just like the abstract syntaxes
1411 Changed YAZ so that it links with compiled ASN.1.
1413 Added Explain-schema definitions and mapping routines. The following
1414 Explain categories have been implemented: AttributeDetails,
1415 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1417 Fixed minor bug in Windows version of Server Library.
1419 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1421 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1423 Added EXTERNAL: UNIverse Resource Report (non-standard).
1425 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1426 ENUMERATED and SET OF.
1428 * Added 'const' to some of the char pointer arguments for the
1429 functions, data1_read_node, data1_getelementbytagname,
1430 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1433 Fixed bug in data1_insert_taggeddata - the last_child member of
1434 parent wasn't initialised.
1436 * Changed data1_read_record and data1_read_node so that the supplied
1437 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1438 doesn't refer to any parts of the "SGML"-buffer.
1440 Fixed bug in server library (Windows version of statserv_remove).
1442 * Changed code so that it compiles as C++. The type definition
1443 of Odr_fun which is a member of Odr_arm was changed. The result is,
1444 that an explicit typecast is needed for the fun pointer when
1445 using Odr_arm - as in:
1446 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1448 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1450 Implemented the new structured date and time definition as approved
1451 by the ZIG. Added schemaId element to the specificTag in Espec-1
1452 (also approved at the last ZIG). Thanks to RVDM.
1454 Added some Object identifiers (RVDM).
1456 Changed the Update Extended Service (RVDM).
1458 Added command "refid" to client which specifies referenceId for
1459 the following requests.
1461 Implemented extended service handling for server. See ztest.c
1462 for an example as well as backend.h. New handlers are registerd
1463 in the Init handler.
1465 * Changed interface for sort in server.
1467 Added new members to statserv_options_block. It allows a server
1468 to read options from another source than just the command line. Thanks
1469 to Charles Woodfield.
1471 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1472 renamed to zboolean. Some C++ compilers complained about the name.
1474 Minor changes to gils.abs. Added index 's' (sort) on title
1475 and date/time-last-modified.
1477 --- 1.4pl2 1998/1/30
1479 Fixed bug in server library regarding inetd mode (-i). This bug
1480 was introduced by release 1.4.
1482 --- 1.4pl1 1998/1/29
1484 Added sort facility in client and backend server interface.
1486 Fixed problem with dependencies in Makefile(s).
1488 Fixed bugs for encoders/decoders of extended services and
1491 Implemented sub-tree feature for schemas. Sub-trees are
1492 referenced in *.abs-files. See explain.abs for an example
1493 of the use of this feature.
1495 Modified bib1.att; local attributes for ANY didn't include
1496 ANY itself (only affects use of the retrieval module).
1498 Fixed bug in plain SGML reader in function data1_read_node:
1499 tags with prefix "var" was incorrectly interpreted as variants.
1501 Added feature "sub-schemas" to enable references to - and definitions
1502 of - group of elements.
1504 * Removed member parent from type data1_element (in data1.h).
1506 Implemented function odr_nullval() that returns the value of
1509 * Removed member num_children from data1_node (in data1.h).
1511 Made NT service interface part of the server library. The
1512 function statserv_main uses the NT service when required and
1513 calls the statserv_start / statserv_close routines.
1515 Routine zget_SearchRequest and zget_PresentRequest fills
1516 resultSetName/Id member with "default" instead of "Default".
1518 Fixed memory leak in server. Request queue member wasn't freed.
1520 Fixed nmem_exit so that memory is freed.
1524 Revised the CCL parser utility to be thread safe.
1526 Added function, oid_ent_to_oid, to replace the function
1527 oid_getoidbyent, which is not thread safe.
1529 * Added nmem_init and nmem_exit to initialize and release
1530 NMEM resources. Function nmem_init should be called once in the
1531 initial thread before NMEM/ODR is used. statserv.c and client.c
1532 have been changed accordingly. The change was necessary to make
1533 NMEM thread safe. The NMEM memory pool is shared amongst threads
1534 in a process. Unix-based applications will still work fine without
1537 Added NT Services interface for the the Z39.50 (statserv) Server.
1538 Refer to the ztest.c source on the usage.
1540 Windows 95/NT port using MSVC5.0. Project files are included in the
1543 * Defined new 'global' handle for the retrieval (data1) system. The
1544 new handled, data1_handle, describes the state of the data1 system.
1545 This handle is passed as first argument to virtually all
1546 data1 related routines. The functions data1_create and data1_destroy
1547 creates and destroys a data1 handle respectively.
1549 Added ODR encode stream member to all backend request structures
1550 init, search, scan etc. This stream should be used to allocate all
1551 memory used for the response when thread safe operation is needed.
1553 Changed the comstack utility, cs_addstr, to be thread safe. The
1554 returned hostname string returned by the function is now part the
1557 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1558 function. The cs_straddr takes a COMSTACK handle as argument, so this
1559 function must be used after cs_create and before bind/connect.
1560 This function is thread safe.
1562 Moved test server to 'ztest' directory - generic server code still
1563 in 'server' directory.
1565 Made prefix query (pquery.c) utility thread safe.
1567 Added new function modifier YAZ_EXPORT to 'export' public DLL
1568 functions when using windows (see include/yconfig.h).
1570 Added definitions to the OID database (util/oid.c) (RVDM).
1572 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1574 Added call to ccl_rpn_delete in client program.
1576 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1577 release of RPN structure.
1579 Added support for C++, headers uses extern "C" for public definitions.
1580 With input from RVDM.
1582 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1583 Thanks to Ronald van der Meer (RVDM).
1585 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1587 Added support for private extensions to the OID database
1588 (oid_setprivateoids()). Thanks to RVDM.
1590 Added optional, physical ANY (key replication)
1592 Fixed null-reference problem in GRS-1 output filter.
1594 Proximity operator added to Prefix Query Format (PQF).
1596 In test client command "base" accepts multiple databases.
1598 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1602 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1604 Smallish bug-fixes in the new encoders/decoders (explain).
1606 Bug fixed in DeleteRequest.
1608 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1610 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1612 Added SOIF syntax (using private OID for now) to retrieval module and client.
1614 Added Update extended service.
1616 Added SearchResult-1 additional info structure.
1618 Added optional CCL (ISO8777) interpreter as separate module. Available
1621 --- 1.2 1996/6/10 (1st anniversary release)
1623 Added Summary record syntax. Lightly tested.
1625 Added OPAC record syntax. Untested.
1627 Added ResourceReport service encoders/decoders. Untested.
1629 Fixed bug in z_Unit - wrong tagging on unitSystem.
1631 Fixed bug in the DiagRecs decoder.
1633 Added options for max PDU size and session timeout to frontend-server.
1635 Added documentation of query-language parsers and other supporting utilities.
1637 [frontend-server] Added Attribute set to the bend_scanrequest API.
1639 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1640 surrogate diagnostics were generated.
1642 [retrieval] Allow multiple local values for attribute.
1644 [retrieval] Allow multiple attributes per element in .abs files. index type.
1646 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1648 --- 1.1pl2 1996/4/10
1650 Minor changes, mostly specific to Zebra's requirements (retrieval)
1654 Repaired bug in frontend server when running multiple listening
1655 endpoints in dynamic mode.
1657 z_External() now won't break if a known, ASN.1 value comes encapsulated
1658 in an octet-string. The value will pass through unmodified in an Odr_oct.
1660 Added a bit of code to the demo client to decode & display
1661 ASN.1-structured records represented in the octet-aligned branch of
1662 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1664 Added z_ext_getentbyref() to the ASN module. Doc updated.
1666 * Completed the SCAN definition in the ASN module. This may break SCAN
1667 code based on older YAZ-versions at compile-time. The fix is easy -
1670 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1671 under the SCAN definition. Remember to initialize this, server-people.
1673 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1674 that this does not extend to ODR and ASN.
1676 Comstack allows insertion of established socket (primarily for
1677 inetd-operation of servers). Doc updated.
1679 Front-end server can now start from the inetd in TCP mode. Doc
1682 --- 1.0pl4 1996/1/24
1686 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1687 the rank and record number.
1689 Adjustments to the frontend server.
1691 Fixed diagnostic BER dumper. It ignored the file argument.
1695 Various changes to retrieval module.
1697 Changed the union discriminators of the protocol files from enums to
1698 ints paired with #defines.
1700 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1703 *Changed operator in the RPN structure to 'roperator', again to avoid a
1706 Fixed problems in Explain decoders/encoders.
1708 --- 1.0pl2 1995/12/6
1710 Memory bug in log module fixed.
1712 --- 1.0pl1 1995/12/5
1714 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1716 Bug in Explain DatabaseInfo module fixed.
1718 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1722 The shift to v1.0 signals that we now consider the *core* functionality
1723 of YAZ reasonably stable (the core being more or less equivalent to
1724 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1725 tested (Explain not at all - though that will happen soonish).
1727 Minor changes to code to support Windows port.
1729 Various minor changes after we're getting to use GRS-1 & co. more.
1731 Added Espec-1 format.
1733 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1734 of the protocol and it cannot be selected when encoding (maps into 'string'
1735 when decoding). Needed to talk to some servers.
1737 Demo client can request simple element set names.
1739 Added Diagnostic Format encoders/decoders.
1741 Added simple Close handling to frontend server (no hooks for resource
1742 reporting yet), and demonstration client.
1744 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1746 --- 1.0b3 1995/08/24
1748 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1749 handled incorrectly when records were requested in the searchResponse. This
1750 will only affect you if you use the frontend-server.
1752 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1753 Test-client will ask for and print GRS1. Ztest will return dummy records
1756 Added Explain encoders/decoders to the service-level API. Untested.
1758 Added Extended Services: Item Order encoders and decoders to the Service-
1759 level API. Untested. We could use a recent copy of the pertinent bits
1760 of the ILL protocol to add those bits.
1762 Added diagnostic format 1 encoders/decoders to the service-level API.
1765 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1766 odr_cons.c, which causes a more correct output.
1768 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1769 was always set to 0 when no records were requested in the searchRequest.
1771 * Added better external-handling. This shouldn't harm old code that
1772 *encodes* externals. It can break code that looks for a
1773 'single-ASN1-type' representation, since those types that are known
1774 are now decoded immediately. Look at the SUTRS sample code in
1775 seshigh.c and client.c. Documentation updated.
1777 Handling of structured records in bend_fetchresponse. Length -1 marks
1778 structured record, type is deduced from format field.
1780 --- 1.0b2 1995/06/27
1781 Fairly quick maintenance release to add SUTRS support.
1783 Fixed handling of SUTRS records in the demonstration client.
1785 * Added format field to the bend_fetchrequest and bend_fetchresponce
1786 structures of the backend API (frontend server). When the record is
1787 returned, the value of the format field is mapped to an OID. The
1788 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1789 of the record. The special value VAL_NONE in the bend_request means
1790 that no specific format was requested by the client. Documentation
1791 updated accordingly. Test server (ztest) will return a fixed dummy
1792 SUTRS record if your client requests SUTRS.
1794 Documentation updated accordingly.
1796 You can now set external libraries and RANLIB support in the top-level
1800 First public release.
