1 Added support for CCL, compiled on the client side, in ZOOM-C. This
2 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
3 input; the resulting query objects can be used for for searching with
4 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
6 YAZ' configure searches for OpenSSL by default.
8 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
9 SL_CTX_use_certificate_file. See
10 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
11 for more info. Thanks to Ko van der Sloot.
15 Bug #600: SRU GET, POST support for yaz-client. Introduced
16 command 'sru' which selects method SOAP/GET/POST.
18 Allow missingValueAction to be specified for the sortspec string -
19 function yaz_sort_spec. By default, the missing value action is null.
20 Use ! to specify "abort". Use = followed by stringvalue to specify default
23 Ensured that Present-handler (if defined) is called in GFS before any call to
24 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
25 searchRetrieve requests.
27 Documentation for YAZ is now based on the Docbook XML/XSLT using
28 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
29 is no longer depending on jade/openjade or docbook-to-man scripts.
30 PDF is no longer part of the distribution - but can optionally be
31 made using DSSSL/jadetex or FOP.
33 Added retrieval handling support in Generic Frontend Server to support
34 conversion between MARC/XML as well as XSLTtransforms. See
35 etc/yazgfs.xml for an example.
37 Added Authentication support to Generic Frontend Server in SRU
38 mode. Authentication using HTTP Basic is supported, as is the use
39 of 'x-username' and 'x-password' parameters in the request itself.
41 Added support for a new character set MARC8s identical to MARC8 except
42 that it converts combined characters to single Unicode characters in the
43 Latin-1 range (when possible).
47 ASN.1 compiler 0.4: generates brief Doxygen file header for
48 generated .h/.c files.
50 Utility yaz_iconv now supports conversion to MARC-8.
52 New facilities for the MARC module. The reading - and writing of
53 content are separate methods for the yaz_marc_t handle. The following
54 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
55 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
56 format). Write functions have prefix yaz_marc_write_.. The existing
57 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
58 available. Removed support for OAI-MARC and simplexml (not the
61 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
62 to be returned for this connection.
66 Allow multiple languages and charsets to be specified with
67 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
68 negcharset iso-8859-1,utf-8
70 Translation of proximity nodes from CQL into PQF now works.
72 Moved to automake 1.8, 1.9.
74 Added function yaz_log_set_handler which allows a log handler to be
75 installed. This handler will be called for all log messages. Output
76 to file is also produced; but that can be disabled by passing NULL
77 fname to yaz_log_init_file.
79 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
81 For SRW (including GFS), accept application/soap+xml as content-type
84 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
85 produces NO stylesheet reference even if a default stylesheet is specified
90 Updated Windows package to include yazd.dll + yazd.lib for the
91 Development component.
93 If the environment variable YAZ_LOG is set, then it is used as a
94 string indicating the default level of logging to use if not
95 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
96 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
97 used as before. So, for example, to omit warnings from YAZ logging,
100 cql_transform() now map structure and other attributes before indexes,
101 so that index-specific structures and other attributes can override
102 defaults. So now a combination of mapping specifications such as:
104 index.dc.date = 1=date-modified 4=5
105 does the right thing.
107 cql_transform() now also respects the "always" mapping specification,
108 which establishes an initial set of attributes to be used for all
109 terms except where overridden by more specific attributes associated
110 with the index, relation or modifier.
112 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
113 which mode to use; one of "post", "get" or "soap" (SRW, default).
115 Fixes for yaz_iconv routines: changed trie-based character set conversions
116 to use only non-negative values for bit fields due to Sun's C compiler not
117 supporting negative values.
119 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
120 sequences where not read correctly. Fix by Rustam Usmanov.
122 Updated win/makefile to use options, settings which makes things
123 compile with VS C 2005.
125 --- 2.1.12 2006/02/01
127 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
129 In ZOOM socket code, use select instead of poll on MacOSX.
131 ZOOM-C now support client-side compilation of CQL into RPN that is
132 sent to the server, enabling CQL to be used against all Z39.50
133 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
134 ZOOM_query object, and submit it using ZOOM_connection_search().
135 The CQL-to-RPN translation uses a configuration file, the name of
136 which must be specified in the Connection's "cqlfile" option.
138 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
139 function, which takes as its start-term parameter a ZOOM_query object
140 (which may have had either CQL or RPN set into it).
143 --- 2.1.10 2005/11/29
145 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
146 GFS to support this as well. Backend handler, bend_srw_update, does the
147 update work. Code contributed by Ko van der Sloot.
149 Allow retrieval of Search Result-1 information in ZOOM by the use of
150 options that are attached to a result set. ZOOM documentation updated
153 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
154 UTF-8 conversion. Patch by Raj Patel.
156 Added option -m to GFS to control formatting of timestamps in log file.
158 Added 'exit' as synonym for 'quit' in yaz-client
160 Added support for specifying SRW resultSetId + resultSetIdleTime in a
161 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
162 for the new members. Patch by Ko van der Sloot.
164 Added support for SRU POST. It is supported for content-type
165 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
167 Do not build the separate Multi-threaded (MT) library libyazthread.la.
168 Instead make the library libyaz.la multi-threaded. Threading as a whole
169 can still be disabled by configure option --disable-threads. Previosly,
170 with older GLIBCs there were problems with MT libs under Apache. This
171 has now been fixed a long time ago.
173 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
176 CQL module modified to be case insensitive for relations/indexes/operations.
178 Fixed bug in CQL transform code: incorrect value relationModifieder
181 Added 'show all' command for yaz-client which retrieves all results
184 Added new yaz-client, xmles, which takes a (private) OID and
185 a document to be sent as an extended service request.
187 Describe new yaz-client commands wait_response and set_auto_wait.
189 Increase TCP/IP listener backlog from 3 (which I am guessing was
190 copied from the SunOS manual entry way back when) so SOMAXCONN, so
191 that the socket will queue as many incoming connections as it's able
192 to handle ongoing connections. In other words, it will never now
193 refuse a connection that it would be able to handle merely because
194 it's not got around to accepting() enough of the pending connections
195 yet. This is the behaviour anyway under Linux, where the listen()
196 argument is ignored; but not under BSD and on systems such as
197 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
198 YAZ-based servers should now be uniform across operating systems in
201 yaz-marcdump uses 64-bit file access on some systems. This is enabled
202 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
203 This allows yaz-marcdump to read large MARC batches (>2 GB).
205 Modified all YAZ source files - except the source which is auto-generated
206 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
209 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
210 corresponding to the existing *_setl() function. These allow option
211 values containing arbitrary valuues.
213 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
214 ZOOM_resultset_sort() in new applications. Its behaviour is identical
215 except that it returns an indicator of whether or not the sort
216 criterion was accepted (0 for OK, -1 for invalid).
220 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
221 MARC output rather than returning "new" buffer.
223 yaz-client warns about unknown init options.
225 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
229 Added support for SRW sort in Generic Frontend Server. Patch
230 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
231 sortKeys - or NULL if none is provided.
233 Fixed bug #307: It was impossible to specify indefinite/no timeout
234 for ZOOM_event. Special timeout value -1 now means indefinite timeout
237 Added support for multiple languages and charsets to be specified in
238 ZOOM. Each charset/language is separated by a blank. If negotiation is
239 in effect in init-response, Option
240 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
241 Code based on patch by Vasiliy Osadchuk.
243 Fixed bug #306: infinite recursion that occurred when calling
244 yaz_log_level_init as the first call (before other log level or
247 Fixed bug in scan handling in front end server: if preferred-Position-In-
248 Response was non-present, a NULL pointer referece was performed.
252 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
253 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
254 now defined for all those error codes. So instead of putting 109 in
255 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
256 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
258 Modified the yaz-marcdump utility to skip garbage bytes between MARC
261 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
263 Program yaz-client now exits and produces an error message if multiple
264 Z39.50 servers are specified on the command line (none or one allowed
267 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
272 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
274 Fixed bug #272: Preserve spacing for CCL terms.
278 Added support for virtual hosts and multiple backend servers for
279 the YAZ frontend server. The configution is XML based and
280 support specificition of CQL to RPN mappings and explain information.
281 See section "Virtual Hosts" in the YAZ manual.
283 Extended OPAC display utility. OPAC display utility renders
284 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
285 to supplement yaz_marc_decode_wrbuf.
287 Fixed a bug in MARC decoder that could caused it to crash for some
288 invalid MARC records. More diagnostics and warnings where added in
289 XML output (warnings, etc are stored in comments).
291 --- 2.0.34 2005/02/08
293 Fixes for UNIX domain sockets. Bug #261.
295 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
297 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
298 Added yaz_marc_subfield_str which defines subfield lead string which is
299 used in YAZ_MARC_LINE format. Default string is blank+$. Added
300 yaz_marc_endline_str which defines end of fields string used in
301 YAZ_MARC_LINE format. Default string is newline.
303 Experimental support for MarcXChange. This format can be produced
304 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
305 http://www.bs.dk/standards/MarcXchange.xsd
307 Added yaz-client commands scansize that sets maximum number of
308 entries to be returned by scan.
310 --- 2.0.32 2005/01/11
312 Added support for SRW scan in yaz-client and Generic Frontend Server.
314 * Added whereInList member to SRW Scan Term.
316 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
318 Fixed NMEM system to return aligned blocks on the smallest boundaries
319 that are suitably aligned for all possible types on the particular
320 architecture YAZ is being built for.
322 --- 2.0.30 2005/01/04
324 Fixed numerious warnings that was issued with newer versions of GCC.
326 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
327 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
330 Make YAZ Generic Frontend Server slightly faster.
332 Enhance (and reduce) logging for Generic Frontend Server.
334 Revert YAZ log system so that it flushes every write operation
335 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
337 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
338 instead of LOG_, due to name clash with syslog(3). LOG_ are still
339 present. New applications should define YAZ_USE_NEW_LOG=1 - this
340 will effectively disable old definitions.
342 --- 2.0.28 2004/11/09
344 Added yaz_log_time_format which specifies log format using
347 Added yaz_log_module_level which returns mask for a module. Value
348 is non-zero mask a if module is enabled; zero if disabled.
350 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
351 in include/yaz/cql.h.
353 Fixed bug #176: Dont throw diagnostics on empty SRU args.
355 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
357 Fixed bug #172: RPM builds does not enable SSL.
359 Doxyfile.in part of dist. Doxyfile generated by configure.
361 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
362 are given and the corresponding component does not exist.
364 Extend CCL documentation in YAZ reference. Describe r=r.
366 --- 2.0.26 2004/10/01
368 Fixed MARC->MARCXML conversion to properly deal with
369 fields, subfields, indicators having non-ASCII characters.
371 Fixed MARC->MARCXML conversion so that ASCII control characters
372 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
375 Added YAZ GFS support for conversion from Z39.50 surrogate
376 diagnostics to SRW surrogate diagnostics.
378 Bug fix: YAZ GFS did not return schema in explainResponse.
380 --- 2.0.25 2004/09/30
382 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
383 now converts recordSchema to elementSetName as well as schema URI.
385 Fixed bug in COMSTACK that prevented HTTP request packages from being
388 --- 2.0.24 2004/09/29
390 Added CCL facility r=r "range" which is similar to r=o "ordered" but
391 does not require white-space before and after the dash in a range, e.g.
392 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
395 Fixed a few AC_TRY_LINK configure tests that did not operate properly
396 due to new GCC removing "redundant" code.
398 Added yaz-client commands scanpos and scanstep that sets preferred
399 position and step-size for scan.
401 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
403 Added CCL utility ccl_qual_buf which parses one or more CCL
404 spec lines in a buffer.
406 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
407 of name and value - ignoring empty lines and comments.
409 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
411 Added odr_get_element_path which returns current element path for an
412 ODR handle. This utility is useful in error handling or user-defined
415 Added ODR_PRINT utility odr_set_stream which is is a more generic
416 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
417 to a write function and pointer to close function. The close function - if
418 non-NULL - will be called during odr_destroy.
420 Fixed bug in CCL parser where truncation char was not removed from
421 right side when truncation=both was in effect.
423 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
426 --- 2.0.23 2004/08/11
428 Fix buffer overrun in CQL parser when dealing with proximity (%).
430 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
431 to UTF-8/UCS conversion is now only based on codetables.xml.
433 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
435 --- 2.0.22 2004/08/06
437 Add support for more "commit changes" in ZOOM (uses Extended Services).
439 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
442 Yet another small fix for configure of SSL.
444 --- 2.0.21 2004/05/14
446 Fix SSL libs for configure when --with-openssl=DIR is given.
448 --- 2.0.20 2004/05/10
450 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
452 SSL comstack now uses yaz.pem certificate file on server side
453 by default. Certificate filename can be configured by calling
454 comstack function cs_set_ssl_certificate_file before cs_bind is used.
456 Fix bug regarding multiple calls to ZOOM_connection_connect.
458 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
460 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
461 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
463 ZOOM now allows inspection of X509 peer certificate for verification.
464 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
466 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
467 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
468 as "modular" but it simplifies things.
470 Added cs_get_peer_certificate to that returns peer X509 PEM.
472 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
473 NULL if SSL is unavailable.
475 Documentation about MARC decoding tools.
477 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
479 --- 2.0.19 2004/03/30
481 Rename CHANGELOG to NEWS to follow GNU style packing.
483 Fix bug with missing initialization of member in init_diagnostics.
484 This bug affects threaded version of GFS server.
486 --- 2.0.18 2004/03/20
488 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
491 Ensure zlib.dll is packed with Windows install.
493 --- 2.0.17 2004/03/17
495 Fix encoding of xsd:string to use text instead of CDATA.
497 Fix endless loop in CQL parser with unbalanced ".
499 Use a more compact way to store MARC-8 conversion tables.
501 --- 2.0.16 2004/03/16 Debian only
503 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
506 Update CQL parser to use new CQL 1.1 modifiers for booleans and
511 --- 2.0.15 2004/03/01
513 Another fix for decoding of XML packed records.
515 --- 2.0.14 2004/02/25
517 Fixes for Chunked encoding. White space not ignored after length spec.
519 Update NS and use default NS for SRW diagnostic elements.
521 --- 2.0.13 2004/02/23
523 Implement ZOOM_resultset_cache_reset which resets record cache.
525 Implement ZOOM_resultset_sort which sorts a result set.
527 Implement chunked HTTP transfer.
529 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
531 --- 2.0.12 2004/02/16
533 Added member 'schema' to bend_explain_rr structure so that backend
534 can specify explain record identifier. Defaults to Zeerex 2.0.
536 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
538 --- 2.0.11 2004/02/16
540 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
543 Added init command for yaz-client which sends "extra" init request.
545 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
546 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
548 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
550 Make ZOOM error code for "invalid query".
552 Fixed compilation for SSL which wasn't properly enabled for all platforms.
554 --- 2.0.10 2004/02/05
556 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
559 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
561 Added option -p <file> to make Generic Frontend Server to write PID file.
563 Added option -D to put Generic Frontend Server in background on its own.
565 Make ZOOM C recognize option "password". If unset, "pass" is used
566 (for backwards compatibility).
568 Fixed a bug in Generic Frontend Server that could make it crash if a
569 client sets characterSetNegotation bit, but didn't pass negotiation stuff
572 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
573 Must be issued before open, in order to be in effect.
575 --- 2.0.9-6 2004/01/12 Debian/Windows
577 Make the SRU server more picky WRT unknown params, etc.
579 Bug fix: ZOOM scan response didn't return displayTerm - when present.
581 New YAZ client command, options, that sets Z39.50 options.
583 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
584 options from a string of tokens (one token for each option bit).
586 Update SRW diagnostic code messages.
588 --- 2.0.9-5 2004/01/07 Debian/Windows
590 Handle user defined stylesheet for SRW/SRU.
592 --- 2.0.9-4 2004/01/06 Debian/Windows
594 Fix bug in decoding of Content-Length.
596 --- 2.0.9-3 2004/01/06 Debian/Windows
598 Fix a bug with decoding of XML packed records.
600 --- 2.0.9-2 2004/01/05 Debian only
602 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
604 Fix bug in SRW/SRU diagnostics decoding.
608 Fixed bug in Generic Frontend Server which could drop records exceeding
609 preferred message size. Reported and fixed by Irina Dijour.
611 Fixed calculation of package size for structured records in Generic
612 Frontend Server. Reported and fixed by Irina Dijour.
614 Fixed namespace for SRW/SRU diagnostics.
616 Fixed SEGV in yaz-client that occured for HTTP connection errors.
620 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
621 this version is incompatible with version 1.0 and older YAZ SRW/SRU
624 CQL changes to reflect recent changes to the specification:
625 * Documentation talks about context sets instead of index sets.
626 * Documentation talks about indexes instead of qualifiers.
627 * The CQL-to-PQF transformer's configuration file now uses
628 "index.set.name = <attributes>" instead of the old form
629 "qualifier.set.name = <attributes>". (Both forms are still
630 understood but the latter is deprecated.)
631 * CQL terms with no explicit index specified are now interpreted as
632 cql.serverChoice instead of srw.serverChoice (which of course
633 behaves exactly the same.)
637 MARC conversion can now generate ISO2709 output in another
638 character set. yaz-marcdump uses this facility if you invoke it
641 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
642 functions from there can be used from C++.
646 Frontend server now transfers memory from decoded packages to stream
649 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
650 references to show up.
652 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
653 the ZOOM Abstract API. The older names for the same options are still
654 also supported for the benefit of old applications.
656 ZOOM-C supports "implementationId" and "implementationVersion" options
657 to go along with "implementationName". These allow the user code to
658 specify identification strings to be sent to servers.
659 Add OID for the new ExtLite attribute set.
661 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
662 as requested/supplid by Ere Maijala <ere@atp.fi>
664 For generic frontend server, reverse the order of
665 "toolkit-supplied / application-supplied" strings sent as implementationId,
666 Name and Version. Also, remove the spaces around the slash. This brings
667 the GFS in line with the behaviour of ZOOM-C on the client side.
669 Add function ZOOM_scanset_display_term.
671 yaz-client shows scan displayTerm if present.
673 Utility yaz-iconv is now installed by default along with the man page
676 Extend configure check for OpenSSL to use pkg-config where available (such
679 Incorporate patch by Morten Bogeskov which allows a Unix file socket
680 server to specify uid/gid/mask for socket using the format
681 unix:[user=uid,][group=gid,][umask=mask,]file=path
682 If file= is omitted the existing format is assumed, e.g.
684 in which case the mask is 0666 (rw for everybody).
686 Major restructure of YAZ source. All source in libyaz is in src directory.
687 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
688 util (utility programs such as ASN.1 compiler, yaz-marcdump).
690 Added man page for utility yaz-marcdump (used to be called marcdump).
691 yaz-marcdump is installed by 'make install'.
693 Fixed a memory leak in Generic Frontend Server that occurred when decoding
694 of incoming package failed.
696 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
698 Change prototype of odr_perror: add const to message string.
700 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
702 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
703 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
704 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
705 DNS lookup. There should not be any compatibility problems with this
706 assuming that blocking=1 or 0 is used.
708 Fix bad reference in UNIX comstack in function cs_addrstr.
710 Fix for compilation on AIX.
712 The generic front-end server (server/seshigh.c) now supports returning
713 Init diagnostics to the client in User-information-field, in
714 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
719 Allow any CQL relation (not just all,any,exact,scr).
721 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
722 that features the same UI.
724 Implemented command update0 in YAZ client which is equivalent to
725 update but uses old of Ext Update ASN.1.
727 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
728 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
729 Previously no OID was used for this info.
731 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
732 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
733 returns 'malformed search term' otherwise.
735 SortResponse member resultCount now set to NULL in sort handler of
738 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
741 Add three new utility functions for translating OIDs between various
742 formats -- symbolic name such as "Usmarc", minus-1-terminated int
743 arrays and dotted strings such as "1.2.840.10003.9.5.1":
744 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
745 char *oid_to_dotstring(const int *oid, char *oidbuf);
746 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
748 Reverted modifications for ES Update definition for z_IU0Update
749 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
750 is back to YAZ 2.0.2.
752 String value attributes for CCL parser.
754 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
755 which their FirstSearch server returns in Init responses, sometimes
756 carrying useful diagnostic information when Init fails. This has the
757 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
758 "z39.50/oclcui.asn", where its definition is somewhat different from
759 what OCLC document on their web-site, as required to interoperate with
762 Support for anonymous authentication in yaz-client. Use the command
765 * Fix the OID of the Index Data-local "admin" Extended Service from
766 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
767 the 1000, which indicates a locally-defined OID, was a mistake.
771 Fix CCL directive @case handling so that it affects string match for
772 both CCL keywords and qualifiers.
774 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
775 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
776 Decoder has been updated with ASN.1 changes as listed in
777 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
778 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
779 z_IUUpdate, remains unchanged.
781 ZOOM_record_get may now return a record in a specific character set.
782 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
783 "from" is the character set of record as returned by target. "to" is
784 the character set to be returned. If omitted, "to" is UTF-8.
786 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
788 New ODR utility, odr_getelement, which returns name of element for
789 which encoding/decoding failed.
791 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
792 in cases where a required element was omitted.
794 Bug fix: some MARC8 sequences were not converted.
796 New ZOOM option "step" which specifies number of records to be
797 retrieved in one chunk. Used in conjunction with "start" and "count".
799 SRW support for yaz-client. Use scheme http: to use it, e.g.
802 yaz-client no longer does (un)intelligent character set conversions
803 by default. Can be enabled with charset and marc_charset commands.
805 xmalloc trace fix for 64-bit systems such as DEC alpha.
807 Solaris 2.6 compile fix.
809 New function, cql_strerror() translates SRW error codes, as returned
810 by cql_transform_error(), into human-readable English strings. Used
811 in yaz-client diagnostics when appropriate.
813 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
814 converts it into a type-1 query which is sent to the server. This
815 makes CQL available for use with all Z-servers, as opposed to the tiny
816 minority that can handle CQL queries themselves.
820 New Debian package layout similar to the Redhat Package layout.
822 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
823 and search result respectively.
827 Redhat package is now several packages: libyaz (runtime libraries),
828 libyaz-devel (development and documentation, and yaz (utility programs).
829 Package spec file by Morten Bøgeskov.
831 New member 'schema' in struct bend_fetch_rr which the name of requested
832 schema (SRW/SRU) for record (or NULL if none was given). The fetch
833 handler MAY set this to reflect the schema of the returned record.
835 New member 'display_term' in struct scan_entry. GFS now sets member entries
836 and allocates scan entries to be filled by user scan handler. In previous
837 version, entries member was allocated by the scan handler. That still works,
838 but the GFS will ignore member display_term - assuming it was NOT set by
839 the handler. The fact that the GFS now allocates the entries both allows
840 for new members and makes a scan handler easier to write.
842 Fix CQL lex buffer overflow.
844 SRW/SRU recordPacking. For SRW default recordPacking is string. For
845 SRU default recordPacking is string.
847 SRU protocol support for frontend server.
849 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
851 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
853 Added scan for the ZOOM shell (zoomsh).
857 * String Identifers for Schemas (Amendment 5).
858 http://lcweb.loc.gov/z3950/agency/amend/am5.html
859 Old definition for schema
860 Odr_oid *schema; /* OPT */
865 Z_InternationalString *uri;
866 #define Z_Schema_oid 1
867 #define Z_Schema_uri 2
870 * resultCount parameter to Sort Response (Amendment 1).
871 http://lcweb.loc.gov/z3950/agency/amend/am1.html
873 Support for SRW 1.0 over HTTP. This is an optional feature and
874 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
877 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
878 on the same port. SRW SearchRetrieveRequests are mapped
879 to bend_init,bend_search,bend_fetch,bend_close.
881 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
883 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
884 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
886 ZOOM connections are SRW based if schem http is used for hostname
887 in connect, e.g. z = ZOOM_connection_new("http://myserver");
888 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
890 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
891 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
892 distance=n, order=true/false, relation=le, prox unit=word. If
893 n is omitted, distance 1 is used.
895 Fixed problem with C compiler include path in wrong order.
897 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
898 on Solaris. Patch from Ko van der Sloot.
900 New MARC decode API. All new functions operate on a yaz_marc_t
901 handle. The most important new functions are: yaz_marc_create,
902 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
903 decode and destroy respectively. Decoder can produce formats
904 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
905 include/yaz/marcdisp.h.
907 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
908 to UTF-8, UCS-32, wchar_t or Latin-1.
910 * Prototypes for yaz_iconv_-functions moved to separate header
911 include/yaz/yaz-iconv.h.
913 Make a few private functions 'static' in unix.c. This prevents
914 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
916 For ZOOM connection, the options targetImplementation{Id,Name,Version}
917 are set when Init Response is received.
919 New function ZOOM_connection_error_x similar to ZOOM_connection_error
920 but returns diagnostic set as well.
922 New function yaz_strerror which is a portable wrapper for
923 strerror/strerror_r/GetLastMessage.
925 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
926 is returned for MARC. If type is "oai", then OAI MARC is returned.
928 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
933 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
935 Fix bad race conditions on SIGTERM and terminate gracefully in
938 Move retrieval (data1) module to Zebra since nobody seems to be
941 Add GRS-1 render for ZOOM using same format as yaz-client.
945 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
947 Fix broken ESpec handling in data1 module.
949 SGML reader parses comments and makes them part of the data1 tree.
951 Added several type casts so that YAZ compiles as C++ code.
953 ZOOM didn't handle PDU encoding failures properly.
955 Added more Bib-1 diagnostics (approved extensions).
957 GNU configure: better check for iconv.
959 More portable use of accept, getpeername. Check for socklen_t. Use
960 int/size_t if socklen_t is not defined.
964 PQF parser rejects bad queries - including those with extra
965 characters in them. PQF parser used to silently ignore that.
966 Cleaner API for PQF added, which allows you to get detailed
967 error information for bad queries (see yaz/pquery.h).
969 Fixed bug in ZOOM_record_get for type "database".
971 Implemented mini iconv library supporting conversions between
972 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
974 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
978 Fixed ZOOM C record cache so that preferredRecordSyntax and
979 elementSetName is used to check for already fetched records.
983 Added three members in bend_initrequest structure to facilitate
984 character set negotiation.
986 Fixed a bug in frontend server that could cause indefinite
987 loops under rare conditions.
989 Revised character set utilities (charneg.h) so that encoding
990 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
992 For PQF, directive @term <type> sets term type for Scan/Search.
993 Here <type> is general, string, numeric, null. The term type
994 is inherited - just like @attr.
996 New call odr_set_charset that sets character set conversion for
997 international-strings on a ODR stream. Prototype is:
998 int odr_set_charset(ODR o, const char *to, const char *from);
999 The InternationalString is still represented as C string in YAZ
1000 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1001 won't). On the protocol level, you can use any encoding.
1003 Support for UNIX sockets in ZOOM.
1005 Solaris recv sometimes returns errno == ENOENT. It is treated as
1006 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1008 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1009 both client and server. Code by Morten Bøgeskov.
1011 --- 1.8.7 2002/05/22
1013 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1014 that they can be used directly from Visual Basic. You must recompile
1015 your windows APP if you're using ZOOM.
1017 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1018 Commands "lang" and "charset" sets language and character set respectively.
1019 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1020 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1022 Attributes from multiple CCL fields may be OR'ed rather than merged
1023 using directive "@field or". Fields are still merged by default -
1024 equivalent to "@field merge".
1026 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1029 Fixed bug in zget for parameter ExtendedServicesResponse.
1033 --- 1.8.6 2002/03/25
1035 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1037 Client displays USR.1:SearchResult-1 (hits per term).
1039 Additional Search Info for search in Generic Frontend Server.
1041 Fixed CCL parsing of "field=s".
1043 WIN32 installer - using the excellent NSIS software from nullsoft.
1045 Fixed CCL parsing of "field = - <number>".
1047 Added function yaz_marc_decode that decodes MARC for line mode
1048 display or XML (similar to that used by JZKit).
1050 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1051 Z39.50. But ISO/ILL was, however.
1053 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1054 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1056 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1057 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1059 --- 1.8.5 2002/02/03
1061 New YAZ client features: Command completion and new commands:
1062 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1063 Code provided by Jacob Poulsen.
1065 New call oid_trav, that visits all registered OIDs via callback.
1067 Function ZOOM_record_get now returns const char pointer rather than
1068 void pointer. It saves a lot of type casts.
1070 For YAZ client, command "auth" now allows you to set authentication
1071 in IdPass style. It is enabled when three tokens are given - order
1072 is user, group and password.
1074 Fix memory leaks in MARC record handling for ZOOM.
1076 New option for YAZ client, -k <kilobytes> that sets
1077 maximum record size. Similar to -k option for generic frontend
1078 server and yaz-ztest.
1080 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1082 Prefix query parser reports "fail" when bad attribute set is given.
1084 Fix in MARC decoder. Proximity logging. Fix for attribute set
1085 in scan handler for server. Patches by Shigeru Ishida.
1087 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1090 Configure option --with-openssl=<dir> now works when a directory is
1091 specified. Patch provided by Morten Bøgeskov.
1093 New option for YAZ client, -u <auth>, that sets authentication.
1095 ZOOM fix: error information was sometimes "missing", since error
1096 was cleared/reset too when it shouldn't.
1098 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1100 --- 1.8.4 2002/01/04
1102 Scan for ZOOM API. New object ZOOM_scanset. New functions
1103 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1104 ZOOM_scanset_destroy.
1106 New ZOOM function, ZOOM_connection_last_event, that returns type
1107 of last event (such as "receive data", "send data", "apdu received",
1110 New ZOOM option, schema, that specifies schema for retrieval.
1112 New CCL feature. Qualifiers can be aliases for one or more
1113 other qualifiers (if more than one is given, OR is used).
1115 ZOOM uses named result sets if target supports it.
1117 Two new YAZ client commands: . (dot, which sources a script of YAZ
1118 client commands), and ! (to execute shell command.). Implemented
1121 Working on Debian packages.
1123 --- 1.8.3 2001/11/19
1125 YAZ client enables named result sets only if target supports it.
1127 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1129 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1130 with key="host" to get same result.
1132 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1133 Function Z3950_resultset_record(s) returns references to records
1134 "owned" by resultset. To become owner use Z3950_record_clone.
1136 Function z_ext_record handles Extended Services. Thanks to
1139 --- 1.8.2 2001/11/12
1141 CCL Parser fix: ignore token comma when dealing with and-lists.
1143 Documentation updates for COMSTACK.
1145 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1146 Changed prototype Z3950_records. For some functions, int parameters
1147 were changed to size_t.
1149 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1152 New MARC decode/display function, marc_display_exl, which properly rejects
1153 non-ISO2709 records. YAZ client uses it.
1155 --- 1.8.1 2001/10/29
1157 Fix bug: local attribute set wasn't set correctly in PQF strings.
1161 * Old Z39.50 codecs no longer supported.
1163 Added ZOOM C binding. See http://zoom.z3950.org/
1165 Renamed states for COMSTACKs to avoid confusion with events.
1167 Implemented cs_look and proper cs_rcvconnect.
1169 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1171 Configure detects POSIX threads on OpenBSD.
1173 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1174 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1176 When error is returned from present handler, non-surrogate diagnostic
1177 is returned in present response (and fetch handler is no longer called).
1179 * Minor adjustments to pquery parser (PQF). Token characters may be
1180 escaped by using backslash (C-style).
1182 PQF parser allows string attribute values to be specified. For @attr,
1183 non-numeric characters after the equal-sign are treated as strings
1184 (e.g. @attr 9=title).
1186 CCL trunction character may be defined (@truncation in file)
1188 * function zget_ExtendedServicesRequest sets waitAction to
1189 waitIfPossible (was wait).
1191 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1194 CCL operator names may be set in field definition files (CCL_bibset).
1195 See ccl/bib1 for an example.
1197 Fixes in ASN.1 compiler for C++ compatibility.
1199 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1200 and "op_or" to avoid conflict with C++.
1202 Fixed problem with GNU readline detection on Redhat 7.0.
1204 Added step-size for Scan backend handler.
1206 Fixed bug that made the frontend server crash when no attribute
1207 set was specified for scan.
1209 Front-end server automatically switches to original working directory
1210 when installed as an NT service. Previously -w had to be specified to
1213 Added extended attributes for retrieval module (data1), so that data1
1214 records carry d1_readXML/SGML attributes. d1_read also supports
1215 null-data rules ( <tag/>)
1217 On UNIX when POSIX threads are available, a separate library libyazthread
1218 is created. Programmers should link with that library and the yaz library
1219 when using threads. The reason for the split was that some applications
1220 on Linux, such as Apache, doesn't work well when using shared objects that
1223 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1224 (or any frontend server) in SSL mode by specifying ssl: followed by
1225 address. Only tested on UNIX.
1227 Added feature for CCL module. Virtual structure s=al or s=ol generates
1228 and-list and or-list respectively instead of phrase search.
1232 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1233 log_mask_str. This was done to avoid name conflicts with other libraries
1234 (such as other PHP extensions).
1236 Added raw OID member for preferred record syntax (request_format_raw)
1237 and returned record syntax (output_format_raw) for backend fetch method.
1239 Config file yaz-config now accepts options so that it returns specific
1240 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1242 Shared library support for UNIX using GNU libtool.
1244 * Modified backend interface. Request/Response struct's replaced by
1245 one read/write C struct. For example bend_fetchrequest and
1246 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1247 Every handler - even search has to be registered in bend_init
1248 handler. This means that the YAZ library no longer refers to
1249 external functions and it makes it possible to make the whole
1250 thing a single DLL/SO.
1252 Added Segment handler for backend server.
1254 Added Zmbol/Zebra administrative functions to YAZ client.
1256 Threaded frontend server on UNIX (when POSIX Threads are available).
1257 Starting the server with option -T enables multi-threading.
1261 Added configure option --enable-comp/disable-comp to control use
1262 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1263 located in sub directory asn.
1265 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1266 in ${exec_prefix}/bin along with the other programs yaz-client and
1269 GNU automake used to maintain makefiles.
1271 Added several OID's.
1273 Changed retrieval module so that we can load records with no abstract
1274 syntax defined. Tagpaths in these records are fully composed of string
1277 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1281 On UNIX, the generated makefile now supports a proper 'make install'.
1282 The prefix can be set via GNU configure to set the install location
1283 (default is /usr/local).
1285 * YAZ programs client and ztest were renamed to yaz-client and
1286 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1287 locations, such as /usr/bin,/usr/local/bin,etc.
1289 * YAZ Header files were moved from include to include/yaz. YAZ Header
1290 files are referred to as include <yaz/log.h> rather than <log.h>.
1291 The YAZ include path (-I ..) is therefore the same as before. Programmers
1292 should update their #include statements or use -Ipath/include/yaz
1293 instead. The main motivation for doing this change is that YAZ header files
1294 can be installed in "standard" locations /usr/include,/usr/local/include
1295 without introducing conflicts, since ALL YAZ header files are stored
1296 in subdirectory yaz (under /usr/include for example).
1298 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1299 rather than project/workspace files. We switched because project files
1300 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1303 Changed name of logging function, logf, to yaz_log, to prevent name
1304 clash with some math-log functions. The YAZ header log.h defines logf
1305 to yaz_log (#define) so there should be no incompatibilities by this
1308 Added bend_start/bend_stop handlers for server. These handler are
1309 called on start/stop of server. For windows they are called whenever
1310 a service is started/stopped.
1312 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1313 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1314 in util/yc.tcl. The auto-generated C code structures are, in a few
1315 cases, incompatible with the old decoders. There are differences in the
1316 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1317 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1318 The preprocessor variable ASN_COMPILED is defined when the compiled
1319 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1320 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1321 wish to use the old encoders/decoders you can specify --disable-yc
1324 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1325 version so that it supports both new - and old version of DB Update
1327 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1328 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1329 change. The name parameter can be set to 0 in which no name is specified
1330 for the construction. The macros odr_implicit and odr_explicit sets name
1331 parameter to zero for the construction involved. New macros
1332 odr_implicit_tag and odr_explicit_tag are similar to the others,
1333 except that a name parameter is added. For programmers' that don't use
1334 ODR they probably only need to change the call to z_APDU and z_External.
1336 Added access control facility by interfacing the TCP wrapper library.
1337 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1338 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1339 name of the daemon and enables the access control as specified in
1340 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1342 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1343 den Dool <H.M.vdnDool@kub.nl>.
1345 Added reference ID parameter to most functions in server API - refer
1346 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1348 Changed name of ccl library to libccl.a (was ccl.a).
1350 Fixed bug in decoder for Explain (Category TargetInfo).
1352 Added support for GNU readline in client. Thanks to Jacob Poulsen
1353 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1355 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1356 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1357 IMPLEMENTATION! This change was made to the development version before
1358 the ZIG decided to retract the amendment. If any users MUST be
1359 compatible with the original Update definition, PLEASE CONTACT US, and
1360 we will include a separate definition corresponding to the old Update
1361 ES. Note that because of the change to the ASN.1 of the
1362 TaskPackageRecordStructure we cannot define a single structure that
1363 will support both versions.
1365 * Added const modifier to buffer parameter for some ODR/BER encoding
1366 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1367 completeWAIS, odr_dumpBER.
1369 Fixed bug in client.c which caused a crash when a scanResponse didn't
1370 contain positionOfTerm.
1372 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1373 * will cause an error in a client if a non-YAZ target sends both a
1374 * list of Scan entries and non-surrogate diagnostics.
1376 Retrieval module enhancements. Tag sets may be typed in the reference
1377 to it. From the .abs-file the "tagset" directive takes a third optional
1378 integer type for the tag set referenced. From a .tag-file the "include"
1379 directive takes a third optional type as well. The old "type" directive
1380 in the tag set itself is still recognized but acts as the default type
1383 Backend interface change. Individual Scan terms returned from bend_scan
1384 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1385 in include/backend.h.
1387 Retrieval module enhancements. Multiple tag sets and attribute sets may
1388 be specified in abstract syntax specs. Revised the error/warning for
1389 logging messages reported by the retrieval module when reading the
1392 Object Identifier system (oid_..) changed. The API is backwards
1393 compatible but the oid-routines now allocates new OID's when needed.
1394 Raw OID's may be specified in oid_getvalbyname.
1396 YAZ now uses GNU configure to generate Makefile(s).
1398 * Minor changes in some of the member names of DeleteResultSetRequest and
1399 DeleteResultSetResponse. See include/proto.h.
1401 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1402 and added member 'languages' in TargetInfo (which was missing).
1404 Changed the way attribute sets are handled in the retrieval
1405 module. These are now cached, just like the abstract syntaxes
1408 Changed YAZ so that it links with compiled ASN.1.
1410 Added Explain-schema definitions and mapping routines. The following
1411 Explain categories have been implemented: AttributeDetails,
1412 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1414 Fixed minor bug in Windows version of Server Library.
1416 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1418 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1420 Added EXTERNAL: UNIverse Resource Report (non-standard).
1422 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1423 ENUMERATED and SET OF.
1425 * Added 'const' to some of the char pointer arguments for the
1426 functions, data1_read_node, data1_getelementbytagname,
1427 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1430 Fixed bug in data1_insert_taggeddata - the last_child member of
1431 parent wasn't initialised.
1433 * Changed data1_read_record and data1_read_node so that the supplied
1434 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1435 doesn't refer to any parts of the "SGML"-buffer.
1437 Fixed bug in server library (Windows version of statserv_remove).
1439 * Changed code so that it compiles as C++. The type definition
1440 of Odr_fun which is a member of Odr_arm was changed. The result is,
1441 that an explicit typecast is needed for the fun pointer when
1442 using Odr_arm - as in:
1443 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1445 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1447 Implemented the new structured date and time definition as approved
1448 by the ZIG. Added schemaId element to the specificTag in Espec-1
1449 (also approved at the last ZIG). Thanks to RVDM.
1451 Added some Object identifiers (RVDM).
1453 Changed the Update Extended Service (RVDM).
1455 Added command "refid" to client which specifies referenceId for
1456 the following requests.
1458 Implemented extended service handling for server. See ztest.c
1459 for an example as well as backend.h. New handlers are registerd
1460 in the Init handler.
1462 * Changed interface for sort in server.
1464 Added new members to statserv_options_block. It allows a server
1465 to read options from another source than just the command line. Thanks
1466 to Charles Woodfield.
1468 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1469 renamed to zboolean. Some C++ compilers complained about the name.
1471 Minor changes to gils.abs. Added index 's' (sort) on title
1472 and date/time-last-modified.
1474 --- 1.4pl2 1998/1/30
1476 Fixed bug in server library regarding inetd mode (-i). This bug
1477 was introduced by release 1.4.
1479 --- 1.4pl1 1998/1/29
1481 Added sort facility in client and backend server interface.
1483 Fixed problem with dependencies in Makefile(s).
1485 Fixed bugs for encoders/decoders of extended services and
1488 Implemented sub-tree feature for schemas. Sub-trees are
1489 referenced in *.abs-files. See explain.abs for an example
1490 of the use of this feature.
1492 Modified bib1.att; local attributes for ANY didn't include
1493 ANY itself (only affects use of the retrieval module).
1495 Fixed bug in plain SGML reader in function data1_read_node:
1496 tags with prefix "var" was incorrectly interpreted as variants.
1498 Added feature "sub-schemas" to enable references to - and definitions
1499 of - group of elements.
1501 * Removed member parent from type data1_element (in data1.h).
1503 Implemented function odr_nullval() that returns the value of
1506 * Removed member num_children from data1_node (in data1.h).
1508 Made NT service interface part of the server library. The
1509 function statserv_main uses the NT service when required and
1510 calls the statserv_start / statserv_close routines.
1512 Routine zget_SearchRequest and zget_PresentRequest fills
1513 resultSetName/Id member with "default" instead of "Default".
1515 Fixed memory leak in server. Request queue member wasn't freed.
1517 Fixed nmem_exit so that memory is freed.
1521 Revised the CCL parser utility to be thread safe.
1523 Added function, oid_ent_to_oid, to replace the function
1524 oid_getoidbyent, which is not thread safe.
1526 * Added nmem_init and nmem_exit to initialize and release
1527 NMEM resources. Function nmem_init should be called once in the
1528 initial thread before NMEM/ODR is used. statserv.c and client.c
1529 have been changed accordingly. The change was necessary to make
1530 NMEM thread safe. The NMEM memory pool is shared amongst threads
1531 in a process. Unix-based applications will still work fine without
1534 Added NT Services interface for the the Z39.50 (statserv) Server.
1535 Refer to the ztest.c source on the usage.
1537 Windows 95/NT port using MSVC5.0. Project files are included in the
1540 * Defined new 'global' handle for the retrieval (data1) system. The
1541 new handled, data1_handle, describes the state of the data1 system.
1542 This handle is passed as first argument to virtually all
1543 data1 related routines. The functions data1_create and data1_destroy
1544 creates and destroys a data1 handle respectively.
1546 Added ODR encode stream member to all backend request structures
1547 init, search, scan etc. This stream should be used to allocate all
1548 memory used for the response when thread safe operation is needed.
1550 Changed the comstack utility, cs_addstr, to be thread safe. The
1551 returned hostname string returned by the function is now part the
1554 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1555 function. The cs_straddr takes a COMSTACK handle as argument, so this
1556 function must be used after cs_create and before bind/connect.
1557 This function is thread safe.
1559 Moved test server to 'ztest' directory - generic server code still
1560 in 'server' directory.
1562 Made prefix query (pquery.c) utility thread safe.
1564 Added new function modifier YAZ_EXPORT to 'export' public DLL
1565 functions when using windows (see include/yconfig.h).
1567 Added definitions to the OID database (util/oid.c) (RVDM).
1569 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1571 Added call to ccl_rpn_delete in client program.
1573 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1574 release of RPN structure.
1576 Added support for C++, headers uses extern "C" for public definitions.
1577 With input from RVDM.
1579 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1580 Thanks to Ronald van der Meer (RVDM).
1582 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1584 Added support for private extensions to the OID database
1585 (oid_setprivateoids()). Thanks to RVDM.
1587 Added optional, physical ANY (key replication)
1589 Fixed null-reference problem in GRS-1 output filter.
1591 Proximity operator added to Prefix Query Format (PQF).
1593 In test client command "base" accepts multiple databases.
1595 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1599 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1601 Smallish bug-fixes in the new encoders/decoders (explain).
1603 Bug fixed in DeleteRequest.
1605 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1607 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1609 Added SOIF syntax (using private OID for now) to retrieval module and client.
1611 Added Update extended service.
1613 Added SearchResult-1 additional info structure.
1615 Added optional CCL (ISO8777) interpreter as separate module. Available
1618 --- 1.2 1996/6/10 (1st anniversary release)
1620 Added Summary record syntax. Lightly tested.
1622 Added OPAC record syntax. Untested.
1624 Added ResourceReport service encoders/decoders. Untested.
1626 Fixed bug in z_Unit - wrong tagging on unitSystem.
1628 Fixed bug in the DiagRecs decoder.
1630 Added options for max PDU size and session timeout to frontend-server.
1632 Added documentation of query-language parsers and other supporting utilities.
1634 [frontend-server] Added Attribute set to the bend_scanrequest API.
1636 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1637 surrogate diagnostics were generated.
1639 [retrieval] Allow multiple local values for attribute.
1641 [retrieval] Allow multiple attributes per element in .abs files. index type.
1643 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1645 --- 1.1pl2 1996/4/10
1647 Minor changes, mostly specific to Zebra's requirements (retrieval)
1651 Repaired bug in frontend server when running multiple listening
1652 endpoints in dynamic mode.
1654 z_External() now won't break if a known, ASN.1 value comes encapsulated
1655 in an octet-string. The value will pass through unmodified in an Odr_oct.
1657 Added a bit of code to the demo client to decode & display
1658 ASN.1-structured records represented in the octet-aligned branch of
1659 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1661 Added z_ext_getentbyref() to the ASN module. Doc updated.
1663 * Completed the SCAN definition in the ASN module. This may break SCAN
1664 code based on older YAZ-versions at compile-time. The fix is easy -
1667 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1668 under the SCAN definition. Remember to initialize this, server-people.
1670 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1671 that this does not extend to ODR and ASN.
1673 Comstack allows insertion of established socket (primarily for
1674 inetd-operation of servers). Doc updated.
1676 Front-end server can now start from the inetd in TCP mode. Doc
1679 --- 1.0pl4 1996/1/24
1683 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1684 the rank and record number.
1686 Adjustments to the frontend server.
1688 Fixed diagnostic BER dumper. It ignored the file argument.
1692 Various changes to retrieval module.
1694 Changed the union discriminators of the protocol files from enums to
1695 ints paired with #defines.
1697 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1700 *Changed operator in the RPN structure to 'roperator', again to avoid a
1703 Fixed problems in Explain decoders/encoders.
1705 --- 1.0pl2 1995/12/6
1707 Memory bug in log module fixed.
1709 --- 1.0pl1 1995/12/5
1711 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1713 Bug in Explain DatabaseInfo module fixed.
1715 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1719 The shift to v1.0 signals that we now consider the *core* functionality
1720 of YAZ reasonably stable (the core being more or less equivalent to
1721 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1722 tested (Explain not at all - though that will happen soonish).
1724 Minor changes to code to support Windows port.
1726 Various minor changes after we're getting to use GRS-1 & co. more.
1728 Added Espec-1 format.
1730 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1731 of the protocol and it cannot be selected when encoding (maps into 'string'
1732 when decoding). Needed to talk to some servers.
1734 Demo client can request simple element set names.
1736 Added Diagnostic Format encoders/decoders.
1738 Added simple Close handling to frontend server (no hooks for resource
1739 reporting yet), and demonstration client.
1741 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1743 --- 1.0b3 1995/08/24
1745 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1746 handled incorrectly when records were requested in the searchResponse. This
1747 will only affect you if you use the frontend-server.
1749 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1750 Test-client will ask for and print GRS1. Ztest will return dummy records
1753 Added Explain encoders/decoders to the service-level API. Untested.
1755 Added Extended Services: Item Order encoders and decoders to the Service-
1756 level API. Untested. We could use a recent copy of the pertinent bits
1757 of the ILL protocol to add those bits.
1759 Added diagnostic format 1 encoders/decoders to the service-level API.
1762 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1763 odr_cons.c, which causes a more correct output.
1765 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1766 was always set to 0 when no records were requested in the searchRequest.
1768 * Added better external-handling. This shouldn't harm old code that
1769 *encodes* externals. It can break code that looks for a
1770 'single-ASN1-type' representation, since those types that are known
1771 are now decoded immediately. Look at the SUTRS sample code in
1772 seshigh.c and client.c. Documentation updated.
1774 Handling of structured records in bend_fetchresponse. Length -1 marks
1775 structured record, type is deduced from format field.
1777 --- 1.0b2 1995/06/27
1778 Fairly quick maintenance release to add SUTRS support.
1780 Fixed handling of SUTRS records in the demonstration client.
1782 * Added format field to the bend_fetchrequest and bend_fetchresponce
1783 structures of the backend API (frontend server). When the record is
1784 returned, the value of the format field is mapped to an OID. The
1785 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1786 of the record. The special value VAL_NONE in the bend_request means
1787 that no specific format was requested by the client. Documentation
1788 updated accordingly. Test server (ztest) will return a fixed dummy
1789 SUTRS record if your client requests SUTRS.
1791 Documentation updated accordingly.
1793 You can now set external libraries and RANLIB support in the top-level
1797 First public release.
