1 --- 2.1.24 [in progress]
3 Fixed MARC ISO2709 encoding routines to deal with character set
6 Minor changes to GFS logging. Database included in search request log
9 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
10 cached/multiple records.
12 Shared libraries are built by default on Unix+configure.
14 Changed cql2pqf transformation to use a different evaluation order. The
15 new order is: always, relation, structure, position, truncation, index
16 and relationModifier. Old order was: always, relation, relationModifier,
17 structure, index, position, truncation. Note that the the latter ones
18 override former ones for identical attributes.. The new scheme means that
19 it is possible to override any existing attribute with a relationModifier.
20 And also that it is possible to override everything for the index rule
21 (except the ones listed in relationModifier). No order is perfect but this
22 one, we believe, covers more real cases.. The "always" should have been
23 called "default", since the attributes there can be overridden with all
26 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
27 compilation phase, but also for yaz-config --cflags output. This allows
28 us to have public headers with Libxml2 stuff in them . It should also,
29 eventually, make Libxml2 checks redundant in packages using YAZ, such
34 Changed SRU update structure bend_update_rr so that SRU diagnostics are
35 stored in uri, message and details.. Previously diagnostics were stored
36 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
37 compatibility.. but he's probably the only one affected, so.
39 Added support for CCL, compiled on the client side, in ZOOM-C. This
40 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
41 input; the resulting query objects can be used for for searching with
42 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
44 YAZ' configure searches for OpenSSL by default.
46 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
47 SL_CTX_use_certificate_file. See
48 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
49 for more info. Thanks to Ko van der Sloot.
53 Bug #600: SRU GET, POST support for yaz-client. Introduced
54 command 'sru' which selects method SOAP/GET/POST.
56 Allow missingValueAction to be specified for the sortspec string -
57 function yaz_sort_spec. By default, the missing value action is null.
58 Use ! to specify "abort". Use = followed by stringvalue to specify default
61 Ensured that Present-handler (if defined) is called in GFS before any call to
62 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
63 searchRetrieve requests.
65 Documentation for YAZ is now based on the Docbook XML/XSLT using
66 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
67 is no longer depending on jade/openjade or docbook-to-man scripts.
68 PDF is no longer part of the distribution - but can optionally be
69 made using DSSSL/jadetex or FOP.
71 Added retrieval handling support in Generic Frontend Server to support
72 conversion between MARC/XML as well as XSLTtransforms. See
73 etc/yazgfs.xml for an example.
75 Added Authentication support to Generic Frontend Server in SRU
76 mode. Authentication using HTTP Basic is supported, as is the use
77 of 'x-username' and 'x-password' parameters in the request itself.
79 Added support for a new character set MARC8s identical to MARC8 except
80 that it converts combined characters to single Unicode characters in the
81 Latin-1 range (when possible).
85 ASN.1 compiler 0.4: generates brief Doxygen file header for
86 generated .h/.c files.
88 Utility yaz_iconv now supports conversion to MARC-8.
90 New facilities for the MARC module. The reading - and writing of
91 content are separate methods for the yaz_marc_t handle. The following
92 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
93 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
94 format). Write functions have prefix yaz_marc_write_.. The existing
95 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
96 available. Removed support for OAI-MARC and simplexml (not the
99 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
100 to be returned for this connection.
102 --- 2.1.16 2006/03/31
104 Allow multiple languages and charsets to be specified with
105 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
106 negcharset iso-8859-1,utf-8
108 Translation of proximity nodes from CQL into PQF now works.
110 Moved to automake 1.8, 1.9.
112 Added function yaz_log_set_handler which allows a log handler to be
113 installed. This handler will be called for all log messages. Output
114 to file is also produced; but that can be disabled by passing NULL
115 fname to yaz_log_init_file.
117 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
119 For SRW (including GFS), accept application/soap+xml as content-type
122 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
123 produces NO stylesheet reference even if a default stylesheet is specified
126 --- 2.1.14 2006/03/14
128 Updated Windows package to include yazd.dll + yazd.lib for the
129 Development component.
131 If the environment variable YAZ_LOG is set, then it is used as a
132 string indicating the default level of logging to use if not
133 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
134 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
135 used as before. So, for example, to omit warnings from YAZ logging,
138 cql_transform() now map structure and other attributes before indexes,
139 so that index-specific structures and other attributes can override
140 defaults. So now a combination of mapping specifications such as:
142 index.dc.date = 1=date-modified 4=5
143 does the right thing.
145 cql_transform() now also respects the "always" mapping specification,
146 which establishes an initial set of attributes to be used for all
147 terms except where overridden by more specific attributes associated
148 with the index, relation or modifier.
150 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
151 which mode to use; one of "post", "get" or "soap" (SRW, default).
153 Fixes for yaz_iconv routines: changed trie-based character set conversions
154 to use only non-negative values for bit fields due to Sun's C compiler not
155 supporting negative values.
157 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
158 sequences where not read correctly. Fix by Rustam Usmanov.
160 Updated win/makefile to use options, settings which makes things
161 compile with VS C 2005.
163 --- 2.1.12 2006/02/01
165 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
167 In ZOOM socket code, use select instead of poll on MacOSX.
169 ZOOM-C now support client-side compilation of CQL into RPN that is
170 sent to the server, enabling CQL to be used against all Z39.50
171 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
172 ZOOM_query object, and submit it using ZOOM_connection_search().
173 The CQL-to-RPN translation uses a configuration file, the name of
174 which must be specified in the Connection's "cqlfile" option.
176 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
177 function, which takes as its start-term parameter a ZOOM_query object
178 (which may have had either CQL or RPN set into it).
181 --- 2.1.10 2005/11/29
183 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
184 GFS to support this as well. Backend handler, bend_srw_update, does the
185 update work. Code contributed by Ko van der Sloot.
187 Allow retrieval of Search Result-1 information in ZOOM by the use of
188 options that are attached to a result set. ZOOM documentation updated
191 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
192 UTF-8 conversion. Patch by Raj Patel.
194 Added option -m to GFS to control formatting of timestamps in log file.
196 Added 'exit' as synonym for 'quit' in yaz-client
198 Added support for specifying SRW resultSetId + resultSetIdleTime in a
199 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
200 for the new members. Patch by Ko van der Sloot.
202 Added support for SRU POST. It is supported for content-type
203 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
205 Do not build the separate Multi-threaded (MT) library libyazthread.la.
206 Instead make the library libyaz.la multi-threaded. Threading as a whole
207 can still be disabled by configure option --disable-threads. Previosly,
208 with older GLIBCs there were problems with MT libs under Apache. This
209 has now been fixed a long time ago.
211 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
214 CQL module modified to be case insensitive for relations/indexes/operations.
216 Fixed bug in CQL transform code: incorrect value relationModifieder
219 Added 'show all' command for yaz-client which retrieves all results
222 Added new yaz-client, xmles, which takes a (private) OID and
223 a document to be sent as an extended service request.
225 Describe new yaz-client commands wait_response and set_auto_wait.
227 Increase TCP/IP listener backlog from 3 (which I am guessing was
228 copied from the SunOS manual entry way back when) so SOMAXCONN, so
229 that the socket will queue as many incoming connections as it's able
230 to handle ongoing connections. In other words, it will never now
231 refuse a connection that it would be able to handle merely because
232 it's not got around to accepting() enough of the pending connections
233 yet. This is the behaviour anyway under Linux, where the listen()
234 argument is ignored; but not under BSD and on systems such as
235 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
236 YAZ-based servers should now be uniform across operating systems in
239 yaz-marcdump uses 64-bit file access on some systems. This is enabled
240 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
241 This allows yaz-marcdump to read large MARC batches (>2 GB).
243 Modified all YAZ source files - except the source which is auto-generated
244 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
247 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
248 corresponding to the existing *_setl() function. These allow option
249 values containing arbitrary valuues.
251 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
252 ZOOM_resultset_sort() in new applications. Its behaviour is identical
253 except that it returns an indicator of whether or not the sort
254 criterion was accepted (0 for OK, -1 for invalid).
258 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
259 MARC output rather than returning "new" buffer.
261 yaz-client warns about unknown init options.
263 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
267 Added support for SRW sort in Generic Frontend Server. Patch
268 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
269 sortKeys - or NULL if none is provided.
271 Fixed bug #307: It was impossible to specify indefinite/no timeout
272 for ZOOM_event. Special timeout value -1 now means indefinite timeout
275 Added support for multiple languages and charsets to be specified in
276 ZOOM. Each charset/language is separated by a blank. If negotiation is
277 in effect in init-response, Option
278 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
279 Code based on patch by Vasiliy Osadchuk.
281 Fixed bug #306: infinite recursion that occurred when calling
282 yaz_log_level_init as the first call (before other log level or
285 Fixed bug in scan handling in front end server: if preferred-Position-In-
286 Response was non-present, a NULL pointer referece was performed.
290 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
291 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
292 now defined for all those error codes. So instead of putting 109 in
293 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
294 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
296 Modified the yaz-marcdump utility to skip garbage bytes between MARC
299 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
301 Program yaz-client now exits and produces an error message if multiple
302 Z39.50 servers are specified on the command line (none or one allowed
305 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
310 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
312 Fixed bug #272: Preserve spacing for CCL terms.
316 Added support for virtual hosts and multiple backend servers for
317 the YAZ frontend server. The configution is XML based and
318 support specificition of CQL to RPN mappings and explain information.
319 See section "Virtual Hosts" in the YAZ manual.
321 Extended OPAC display utility. OPAC display utility renders
322 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
323 to supplement yaz_marc_decode_wrbuf.
325 Fixed a bug in MARC decoder that could caused it to crash for some
326 invalid MARC records. More diagnostics and warnings where added in
327 XML output (warnings, etc are stored in comments).
329 --- 2.0.34 2005/02/08
331 Fixes for UNIX domain sockets. Bug #261.
333 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
335 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
336 Added yaz_marc_subfield_str which defines subfield lead string which is
337 used in YAZ_MARC_LINE format. Default string is blank+$. Added
338 yaz_marc_endline_str which defines end of fields string used in
339 YAZ_MARC_LINE format. Default string is newline.
341 Experimental support for MarcXChange. This format can be produced
342 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
343 http://www.bs.dk/standards/MarcXchange.xsd
345 Added yaz-client commands scansize that sets maximum number of
346 entries to be returned by scan.
348 --- 2.0.32 2005/01/11
350 Added support for SRW scan in yaz-client and Generic Frontend Server.
352 * Added whereInList member to SRW Scan Term.
354 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
356 Fixed NMEM system to return aligned blocks on the smallest boundaries
357 that are suitably aligned for all possible types on the particular
358 architecture YAZ is being built for.
360 --- 2.0.30 2005/01/04
362 Fixed numerious warnings that was issued with newer versions of GCC.
364 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
365 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
368 Make YAZ Generic Frontend Server slightly faster.
370 Enhance (and reduce) logging for Generic Frontend Server.
372 Revert YAZ log system so that it flushes every write operation
373 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
375 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
376 instead of LOG_, due to name clash with syslog(3). LOG_ are still
377 present. New applications should define YAZ_USE_NEW_LOG=1 - this
378 will effectively disable old definitions.
380 --- 2.0.28 2004/11/09
382 Added yaz_log_time_format which specifies log format using
385 Added yaz_log_module_level which returns mask for a module. Value
386 is non-zero mask a if module is enabled; zero if disabled.
388 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
389 in include/yaz/cql.h.
391 Fixed bug #176: Dont throw diagnostics on empty SRU args.
393 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
395 Fixed bug #172: RPM builds does not enable SSL.
397 Doxyfile.in part of dist. Doxyfile generated by configure.
399 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
400 are given and the corresponding component does not exist.
402 Extend CCL documentation in YAZ reference. Describe r=r.
404 --- 2.0.26 2004/10/01
406 Fixed MARC->MARCXML conversion to properly deal with
407 fields, subfields, indicators having non-ASCII characters.
409 Fixed MARC->MARCXML conversion so that ASCII control characters
410 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
413 Added YAZ GFS support for conversion from Z39.50 surrogate
414 diagnostics to SRW surrogate diagnostics.
416 Bug fix: YAZ GFS did not return schema in explainResponse.
418 --- 2.0.25 2004/09/30
420 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
421 now converts recordSchema to elementSetName as well as schema URI.
423 Fixed bug in COMSTACK that prevented HTTP request packages from being
426 --- 2.0.24 2004/09/29
428 Added CCL facility r=r "range" which is similar to r=o "ordered" but
429 does not require white-space before and after the dash in a range, e.g.
430 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
433 Fixed a few AC_TRY_LINK configure tests that did not operate properly
434 due to new GCC removing "redundant" code.
436 Added yaz-client commands scanpos and scanstep that sets preferred
437 position and step-size for scan.
439 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
441 Added CCL utility ccl_qual_buf which parses one or more CCL
442 spec lines in a buffer.
444 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
445 of name and value - ignoring empty lines and comments.
447 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
449 Added odr_get_element_path which returns current element path for an
450 ODR handle. This utility is useful in error handling or user-defined
453 Added ODR_PRINT utility odr_set_stream which is is a more generic
454 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
455 to a write function and pointer to close function. The close function - if
456 non-NULL - will be called during odr_destroy.
458 Fixed bug in CCL parser where truncation char was not removed from
459 right side when truncation=both was in effect.
461 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
464 --- 2.0.23 2004/08/11
466 Fix buffer overrun in CQL parser when dealing with proximity (%).
468 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
469 to UTF-8/UCS conversion is now only based on codetables.xml.
471 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
473 --- 2.0.22 2004/08/06
475 Add support for more "commit changes" in ZOOM (uses Extended Services).
477 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
480 Yet another small fix for configure of SSL.
482 --- 2.0.21 2004/05/14
484 Fix SSL libs for configure when --with-openssl=DIR is given.
486 --- 2.0.20 2004/05/10
488 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
490 SSL comstack now uses yaz.pem certificate file on server side
491 by default. Certificate filename can be configured by calling
492 comstack function cs_set_ssl_certificate_file before cs_bind is used.
494 Fix bug regarding multiple calls to ZOOM_connection_connect.
496 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
498 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
499 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
501 ZOOM now allows inspection of X509 peer certificate for verification.
502 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
504 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
505 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
506 as "modular" but it simplifies things.
508 Added cs_get_peer_certificate to that returns peer X509 PEM.
510 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
511 NULL if SSL is unavailable.
513 Documentation about MARC decoding tools.
515 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
517 --- 2.0.19 2004/03/30
519 Rename CHANGELOG to NEWS to follow GNU style packing.
521 Fix bug with missing initialization of member in init_diagnostics.
522 This bug affects threaded version of GFS server.
524 --- 2.0.18 2004/03/20
526 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
529 Ensure zlib.dll is packed with Windows install.
531 --- 2.0.17 2004/03/17
533 Fix encoding of xsd:string to use text instead of CDATA.
535 Fix endless loop in CQL parser with unbalanced ".
537 Use a more compact way to store MARC-8 conversion tables.
539 --- 2.0.16 2004/03/16 Debian only
541 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
544 Update CQL parser to use new CQL 1.1 modifiers for booleans and
549 --- 2.0.15 2004/03/01
551 Another fix for decoding of XML packed records.
553 --- 2.0.14 2004/02/25
555 Fixes for Chunked encoding. White space not ignored after length spec.
557 Update NS and use default NS for SRW diagnostic elements.
559 --- 2.0.13 2004/02/23
561 Implement ZOOM_resultset_cache_reset which resets record cache.
563 Implement ZOOM_resultset_sort which sorts a result set.
565 Implement chunked HTTP transfer.
567 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
569 --- 2.0.12 2004/02/16
571 Added member 'schema' to bend_explain_rr structure so that backend
572 can specify explain record identifier. Defaults to Zeerex 2.0.
574 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
576 --- 2.0.11 2004/02/16
578 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
581 Added init command for yaz-client which sends "extra" init request.
583 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
584 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
586 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
588 Make ZOOM error code for "invalid query".
590 Fixed compilation for SSL which wasn't properly enabled for all platforms.
592 --- 2.0.10 2004/02/05
594 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
597 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
599 Added option -p <file> to make Generic Frontend Server to write PID file.
601 Added option -D to put Generic Frontend Server in background on its own.
603 Make ZOOM C recognize option "password". If unset, "pass" is used
604 (for backwards compatibility).
606 Fixed a bug in Generic Frontend Server that could make it crash if a
607 client sets characterSetNegotation bit, but didn't pass negotiation stuff
610 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
611 Must be issued before open, in order to be in effect.
613 --- 2.0.9-6 2004/01/12 Debian/Windows
615 Make the SRU server more picky WRT unknown params, etc.
617 Bug fix: ZOOM scan response didn't return displayTerm - when present.
619 New YAZ client command, options, that sets Z39.50 options.
621 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
622 options from a string of tokens (one token for each option bit).
624 Update SRW diagnostic code messages.
626 --- 2.0.9-5 2004/01/07 Debian/Windows
628 Handle user defined stylesheet for SRW/SRU.
630 --- 2.0.9-4 2004/01/06 Debian/Windows
632 Fix bug in decoding of Content-Length.
634 --- 2.0.9-3 2004/01/06 Debian/Windows
636 Fix a bug with decoding of XML packed records.
638 --- 2.0.9-2 2004/01/05 Debian only
640 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
642 Fix bug in SRW/SRU diagnostics decoding.
646 Fixed bug in Generic Frontend Server which could drop records exceeding
647 preferred message size. Reported and fixed by Irina Dijour.
649 Fixed calculation of package size for structured records in Generic
650 Frontend Server. Reported and fixed by Irina Dijour.
652 Fixed namespace for SRW/SRU diagnostics.
654 Fixed SEGV in yaz-client that occured for HTTP connection errors.
658 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
659 this version is incompatible with version 1.0 and older YAZ SRW/SRU
662 CQL changes to reflect recent changes to the specification:
663 * Documentation talks about context sets instead of index sets.
664 * Documentation talks about indexes instead of qualifiers.
665 * The CQL-to-PQF transformer's configuration file now uses
666 "index.set.name = <attributes>" instead of the old form
667 "qualifier.set.name = <attributes>". (Both forms are still
668 understood but the latter is deprecated.)
669 * CQL terms with no explicit index specified are now interpreted as
670 cql.serverChoice instead of srw.serverChoice (which of course
671 behaves exactly the same.)
675 MARC conversion can now generate ISO2709 output in another
676 character set. yaz-marcdump uses this facility if you invoke it
679 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
680 functions from there can be used from C++.
684 Frontend server now transfers memory from decoded packages to stream
687 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
688 references to show up.
690 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
691 the ZOOM Abstract API. The older names for the same options are still
692 also supported for the benefit of old applications.
694 ZOOM-C supports "implementationId" and "implementationVersion" options
695 to go along with "implementationName". These allow the user code to
696 specify identification strings to be sent to servers.
697 Add OID for the new ExtLite attribute set.
699 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
700 as requested/supplid by Ere Maijala <ere@atp.fi>
702 For generic frontend server, reverse the order of
703 "toolkit-supplied / application-supplied" strings sent as implementationId,
704 Name and Version. Also, remove the spaces around the slash. This brings
705 the GFS in line with the behaviour of ZOOM-C on the client side.
707 Add function ZOOM_scanset_display_term.
709 yaz-client shows scan displayTerm if present.
711 Utility yaz-iconv is now installed by default along with the man page
714 Extend configure check for OpenSSL to use pkg-config where available (such
717 Incorporate patch by Morten Bogeskov which allows a Unix file socket
718 server to specify uid/gid/mask for socket using the format
719 unix:[user=uid,][group=gid,][umask=mask,]file=path
720 If file= is omitted the existing format is assumed, e.g.
722 in which case the mask is 0666 (rw for everybody).
724 Major restructure of YAZ source. All source in libyaz is in src directory.
725 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
726 util (utility programs such as ASN.1 compiler, yaz-marcdump).
728 Added man page for utility yaz-marcdump (used to be called marcdump).
729 yaz-marcdump is installed by 'make install'.
731 Fixed a memory leak in Generic Frontend Server that occurred when decoding
732 of incoming package failed.
734 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
736 Change prototype of odr_perror: add const to message string.
738 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
740 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
741 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
742 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
743 DNS lookup. There should not be any compatibility problems with this
744 assuming that blocking=1 or 0 is used.
746 Fix bad reference in UNIX comstack in function cs_addrstr.
748 Fix for compilation on AIX.
750 The generic front-end server (server/seshigh.c) now supports returning
751 Init diagnostics to the client in User-information-field, in
752 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
757 Allow any CQL relation (not just all,any,exact,scr).
759 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
760 that features the same UI.
762 Implemented command update0 in YAZ client which is equivalent to
763 update but uses old of Ext Update ASN.1.
765 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
766 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
767 Previously no OID was used for this info.
769 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
770 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
771 returns 'malformed search term' otherwise.
773 SortResponse member resultCount now set to NULL in sort handler of
776 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
779 Add three new utility functions for translating OIDs between various
780 formats -- symbolic name such as "Usmarc", minus-1-terminated int
781 arrays and dotted strings such as "1.2.840.10003.9.5.1":
782 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
783 char *oid_to_dotstring(const int *oid, char *oidbuf);
784 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
786 Reverted modifications for ES Update definition for z_IU0Update
787 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
788 is back to YAZ 2.0.2.
790 String value attributes for CCL parser.
792 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
793 which their FirstSearch server returns in Init responses, sometimes
794 carrying useful diagnostic information when Init fails. This has the
795 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
796 "z39.50/oclcui.asn", where its definition is somewhat different from
797 what OCLC document on their web-site, as required to interoperate with
800 Support for anonymous authentication in yaz-client. Use the command
803 * Fix the OID of the Index Data-local "admin" Extended Service from
804 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
805 the 1000, which indicates a locally-defined OID, was a mistake.
809 Fix CCL directive @case handling so that it affects string match for
810 both CCL keywords and qualifiers.
812 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
813 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
814 Decoder has been updated with ASN.1 changes as listed in
815 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
816 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
817 z_IUUpdate, remains unchanged.
819 ZOOM_record_get may now return a record in a specific character set.
820 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
821 "from" is the character set of record as returned by target. "to" is
822 the character set to be returned. If omitted, "to" is UTF-8.
824 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
826 New ODR utility, odr_getelement, which returns name of element for
827 which encoding/decoding failed.
829 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
830 in cases where a required element was omitted.
832 Bug fix: some MARC8 sequences were not converted.
834 New ZOOM option "step" which specifies number of records to be
835 retrieved in one chunk. Used in conjunction with "start" and "count".
837 SRW support for yaz-client. Use scheme http: to use it, e.g.
840 yaz-client no longer does (un)intelligent character set conversions
841 by default. Can be enabled with charset and marc_charset commands.
843 xmalloc trace fix for 64-bit systems such as DEC alpha.
845 Solaris 2.6 compile fix.
847 New function, cql_strerror() translates SRW error codes, as returned
848 by cql_transform_error(), into human-readable English strings. Used
849 in yaz-client diagnostics when appropriate.
851 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
852 converts it into a type-1 query which is sent to the server. This
853 makes CQL available for use with all Z-servers, as opposed to the tiny
854 minority that can handle CQL queries themselves.
858 New Debian package layout similar to the Redhat Package layout.
860 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
861 and search result respectively.
865 Redhat package is now several packages: libyaz (runtime libraries),
866 libyaz-devel (development and documentation, and yaz (utility programs).
867 Package spec file by Morten Bøgeskov.
869 New member 'schema' in struct bend_fetch_rr which the name of requested
870 schema (SRW/SRU) for record (or NULL if none was given). The fetch
871 handler MAY set this to reflect the schema of the returned record.
873 New member 'display_term' in struct scan_entry. GFS now sets member entries
874 and allocates scan entries to be filled by user scan handler. In previous
875 version, entries member was allocated by the scan handler. That still works,
876 but the GFS will ignore member display_term - assuming it was NOT set by
877 the handler. The fact that the GFS now allocates the entries both allows
878 for new members and makes a scan handler easier to write.
880 Fix CQL lex buffer overflow.
882 SRW/SRU recordPacking. For SRW default recordPacking is string. For
883 SRU default recordPacking is string.
885 SRU protocol support for frontend server.
887 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
889 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
891 Added scan for the ZOOM shell (zoomsh).
895 * String Identifers for Schemas (Amendment 5).
896 http://lcweb.loc.gov/z3950/agency/amend/am5.html
897 Old definition for schema
898 Odr_oid *schema; /* OPT */
903 Z_InternationalString *uri;
904 #define Z_Schema_oid 1
905 #define Z_Schema_uri 2
908 * resultCount parameter to Sort Response (Amendment 1).
909 http://lcweb.loc.gov/z3950/agency/amend/am1.html
911 Support for SRW 1.0 over HTTP. This is an optional feature and
912 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
915 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
916 on the same port. SRW SearchRetrieveRequests are mapped
917 to bend_init,bend_search,bend_fetch,bend_close.
919 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
921 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
922 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
924 ZOOM connections are SRW based if schem http is used for hostname
925 in connect, e.g. z = ZOOM_connection_new("http://myserver");
926 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
928 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
929 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
930 distance=n, order=true/false, relation=le, prox unit=word. If
931 n is omitted, distance 1 is used.
933 Fixed problem with C compiler include path in wrong order.
935 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
936 on Solaris. Patch from Ko van der Sloot.
938 New MARC decode API. All new functions operate on a yaz_marc_t
939 handle. The most important new functions are: yaz_marc_create,
940 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
941 decode and destroy respectively. Decoder can produce formats
942 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
943 include/yaz/marcdisp.h.
945 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
946 to UTF-8, UCS-32, wchar_t or Latin-1.
948 * Prototypes for yaz_iconv_-functions moved to separate header
949 include/yaz/yaz-iconv.h.
951 Make a few private functions 'static' in unix.c. This prevents
952 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
954 For ZOOM connection, the options targetImplementation{Id,Name,Version}
955 are set when Init Response is received.
957 New function ZOOM_connection_error_x similar to ZOOM_connection_error
958 but returns diagnostic set as well.
960 New function yaz_strerror which is a portable wrapper for
961 strerror/strerror_r/GetLastMessage.
963 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
964 is returned for MARC. If type is "oai", then OAI MARC is returned.
966 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
971 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
973 Fix bad race conditions on SIGTERM and terminate gracefully in
976 Move retrieval (data1) module to Zebra since nobody seems to be
979 Add GRS-1 render for ZOOM using same format as yaz-client.
983 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
985 Fix broken ESpec handling in data1 module.
987 SGML reader parses comments and makes them part of the data1 tree.
989 Added several type casts so that YAZ compiles as C++ code.
991 ZOOM didn't handle PDU encoding failures properly.
993 Added more Bib-1 diagnostics (approved extensions).
995 GNU configure: better check for iconv.
997 More portable use of accept, getpeername. Check for socklen_t. Use
998 int/size_t if socklen_t is not defined.
1002 PQF parser rejects bad queries - including those with extra
1003 characters in them. PQF parser used to silently ignore that.
1004 Cleaner API for PQF added, which allows you to get detailed
1005 error information for bad queries (see yaz/pquery.h).
1007 Fixed bug in ZOOM_record_get for type "database".
1009 Implemented mini iconv library supporting conversions between
1010 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1012 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1014 --- 1.8.9 2002/08/20
1016 Fixed ZOOM C record cache so that preferredRecordSyntax and
1017 elementSetName is used to check for already fetched records.
1019 --- 1.8.8 2002/08/02
1021 Added three members in bend_initrequest structure to facilitate
1022 character set negotiation.
1024 Fixed a bug in frontend server that could cause indefinite
1025 loops under rare conditions.
1027 Revised character set utilities (charneg.h) so that encoding
1028 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1030 For PQF, directive @term <type> sets term type for Scan/Search.
1031 Here <type> is general, string, numeric, null. The term type
1032 is inherited - just like @attr.
1034 New call odr_set_charset that sets character set conversion for
1035 international-strings on a ODR stream. Prototype is:
1036 int odr_set_charset(ODR o, const char *to, const char *from);
1037 The InternationalString is still represented as C string in YAZ
1038 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1039 won't). On the protocol level, you can use any encoding.
1041 Support for UNIX sockets in ZOOM.
1043 Solaris recv sometimes returns errno == ENOENT. It is treated as
1044 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1046 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1047 both client and server. Code by Morten Bøgeskov.
1049 --- 1.8.7 2002/05/22
1051 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1052 that they can be used directly from Visual Basic. You must recompile
1053 your windows APP if you're using ZOOM.
1055 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1056 Commands "lang" and "charset" sets language and character set respectively.
1057 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1058 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1060 Attributes from multiple CCL fields may be OR'ed rather than merged
1061 using directive "@field or". Fields are still merged by default -
1062 equivalent to "@field merge".
1064 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1067 Fixed bug in zget for parameter ExtendedServicesResponse.
1071 --- 1.8.6 2002/03/25
1073 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1075 Client displays USR.1:SearchResult-1 (hits per term).
1077 Additional Search Info for search in Generic Frontend Server.
1079 Fixed CCL parsing of "field=s".
1081 WIN32 installer - using the excellent NSIS software from nullsoft.
1083 Fixed CCL parsing of "field = - <number>".
1085 Added function yaz_marc_decode that decodes MARC for line mode
1086 display or XML (similar to that used by JZKit).
1088 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1089 Z39.50. But ISO/ILL was, however.
1091 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1092 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1094 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1095 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1097 --- 1.8.5 2002/02/03
1099 New YAZ client features: Command completion and new commands:
1100 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1101 Code provided by Jacob Poulsen.
1103 New call oid_trav, that visits all registered OIDs via callback.
1105 Function ZOOM_record_get now returns const char pointer rather than
1106 void pointer. It saves a lot of type casts.
1108 For YAZ client, command "auth" now allows you to set authentication
1109 in IdPass style. It is enabled when three tokens are given - order
1110 is user, group and password.
1112 Fix memory leaks in MARC record handling for ZOOM.
1114 New option for YAZ client, -k <kilobytes> that sets
1115 maximum record size. Similar to -k option for generic frontend
1116 server and yaz-ztest.
1118 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1120 Prefix query parser reports "fail" when bad attribute set is given.
1122 Fix in MARC decoder. Proximity logging. Fix for attribute set
1123 in scan handler for server. Patches by Shigeru Ishida.
1125 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1128 Configure option --with-openssl=<dir> now works when a directory is
1129 specified. Patch provided by Morten Bøgeskov.
1131 New option for YAZ client, -u <auth>, that sets authentication.
1133 ZOOM fix: error information was sometimes "missing", since error
1134 was cleared/reset too when it shouldn't.
1136 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1138 --- 1.8.4 2002/01/04
1140 Scan for ZOOM API. New object ZOOM_scanset. New functions
1141 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1142 ZOOM_scanset_destroy.
1144 New ZOOM function, ZOOM_connection_last_event, that returns type
1145 of last event (such as "receive data", "send data", "apdu received",
1148 New ZOOM option, schema, that specifies schema for retrieval.
1150 New CCL feature. Qualifiers can be aliases for one or more
1151 other qualifiers (if more than one is given, OR is used).
1153 ZOOM uses named result sets if target supports it.
1155 Two new YAZ client commands: . (dot, which sources a script of YAZ
1156 client commands), and ! (to execute shell command.). Implemented
1159 Working on Debian packages.
1161 --- 1.8.3 2001/11/19
1163 YAZ client enables named result sets only if target supports it.
1165 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1167 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1168 with key="host" to get same result.
1170 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1171 Function Z3950_resultset_record(s) returns references to records
1172 "owned" by resultset. To become owner use Z3950_record_clone.
1174 Function z_ext_record handles Extended Services. Thanks to
1177 --- 1.8.2 2001/11/12
1179 CCL Parser fix: ignore token comma when dealing with and-lists.
1181 Documentation updates for COMSTACK.
1183 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1184 Changed prototype Z3950_records. For some functions, int parameters
1185 were changed to size_t.
1187 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1190 New MARC decode/display function, marc_display_exl, which properly rejects
1191 non-ISO2709 records. YAZ client uses it.
1193 --- 1.8.1 2001/10/29
1195 Fix bug: local attribute set wasn't set correctly in PQF strings.
1199 * Old Z39.50 codecs no longer supported.
1201 Added ZOOM C binding. See http://zoom.z3950.org/
1203 Renamed states for COMSTACKs to avoid confusion with events.
1205 Implemented cs_look and proper cs_rcvconnect.
1207 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1209 Configure detects POSIX threads on OpenBSD.
1211 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1212 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1214 When error is returned from present handler, non-surrogate diagnostic
1215 is returned in present response (and fetch handler is no longer called).
1217 * Minor adjustments to pquery parser (PQF). Token characters may be
1218 escaped by using backslash (C-style).
1220 PQF parser allows string attribute values to be specified. For @attr,
1221 non-numeric characters after the equal-sign are treated as strings
1222 (e.g. @attr 9=title).
1224 CCL trunction character may be defined (@truncation in file)
1226 * function zget_ExtendedServicesRequest sets waitAction to
1227 waitIfPossible (was wait).
1229 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1232 CCL operator names may be set in field definition files (CCL_bibset).
1233 See ccl/bib1 for an example.
1235 Fixes in ASN.1 compiler for C++ compatibility.
1237 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1238 and "op_or" to avoid conflict with C++.
1240 Fixed problem with GNU readline detection on Redhat 7.0.
1242 Added step-size for Scan backend handler.
1244 Fixed bug that made the frontend server crash when no attribute
1245 set was specified for scan.
1247 Front-end server automatically switches to original working directory
1248 when installed as an NT service. Previously -w had to be specified to
1251 Added extended attributes for retrieval module (data1), so that data1
1252 records carry d1_readXML/SGML attributes. d1_read also supports
1253 null-data rules ( <tag/>)
1255 On UNIX when POSIX threads are available, a separate library libyazthread
1256 is created. Programmers should link with that library and the yaz library
1257 when using threads. The reason for the split was that some applications
1258 on Linux, such as Apache, doesn't work well when using shared objects that
1261 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1262 (or any frontend server) in SSL mode by specifying ssl: followed by
1263 address. Only tested on UNIX.
1265 Added feature for CCL module. Virtual structure s=al or s=ol generates
1266 and-list and or-list respectively instead of phrase search.
1270 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1271 log_mask_str. This was done to avoid name conflicts with other libraries
1272 (such as other PHP extensions).
1274 Added raw OID member for preferred record syntax (request_format_raw)
1275 and returned record syntax (output_format_raw) for backend fetch method.
1277 Config file yaz-config now accepts options so that it returns specific
1278 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1280 Shared library support for UNIX using GNU libtool.
1282 * Modified backend interface. Request/Response struct's replaced by
1283 one read/write C struct. For example bend_fetchrequest and
1284 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1285 Every handler - even search has to be registered in bend_init
1286 handler. This means that the YAZ library no longer refers to
1287 external functions and it makes it possible to make the whole
1288 thing a single DLL/SO.
1290 Added Segment handler for backend server.
1292 Added Zmbol/Zebra administrative functions to YAZ client.
1294 Threaded frontend server on UNIX (when POSIX Threads are available).
1295 Starting the server with option -T enables multi-threading.
1299 Added configure option --enable-comp/disable-comp to control use
1300 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1301 located in sub directory asn.
1303 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1304 in ${exec_prefix}/bin along with the other programs yaz-client and
1307 GNU automake used to maintain makefiles.
1309 Added several OID's.
1311 Changed retrieval module so that we can load records with no abstract
1312 syntax defined. Tagpaths in these records are fully composed of string
1315 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1319 On UNIX, the generated makefile now supports a proper 'make install'.
1320 The prefix can be set via GNU configure to set the install location
1321 (default is /usr/local).
1323 * YAZ programs client and ztest were renamed to yaz-client and
1324 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1325 locations, such as /usr/bin,/usr/local/bin,etc.
1327 * YAZ Header files were moved from include to include/yaz. YAZ Header
1328 files are referred to as include <yaz/log.h> rather than <log.h>.
1329 The YAZ include path (-I ..) is therefore the same as before. Programmers
1330 should update their #include statements or use -Ipath/include/yaz
1331 instead. The main motivation for doing this change is that YAZ header files
1332 can be installed in "standard" locations /usr/include,/usr/local/include
1333 without introducing conflicts, since ALL YAZ header files are stored
1334 in subdirectory yaz (under /usr/include for example).
1336 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1337 rather than project/workspace files. We switched because project files
1338 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1341 Changed name of logging function, logf, to yaz_log, to prevent name
1342 clash with some math-log functions. The YAZ header log.h defines logf
1343 to yaz_log (#define) so there should be no incompatibilities by this
1346 Added bend_start/bend_stop handlers for server. These handler are
1347 called on start/stop of server. For windows they are called whenever
1348 a service is started/stopped.
1350 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1351 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1352 in util/yc.tcl. The auto-generated C code structures are, in a few
1353 cases, incompatible with the old decoders. There are differences in the
1354 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1355 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1356 The preprocessor variable ASN_COMPILED is defined when the compiled
1357 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1358 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1359 wish to use the old encoders/decoders you can specify --disable-yc
1362 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1363 version so that it supports both new - and old version of DB Update
1365 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1366 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1367 change. The name parameter can be set to 0 in which no name is specified
1368 for the construction. The macros odr_implicit and odr_explicit sets name
1369 parameter to zero for the construction involved. New macros
1370 odr_implicit_tag and odr_explicit_tag are similar to the others,
1371 except that a name parameter is added. For programmers' that don't use
1372 ODR they probably only need to change the call to z_APDU and z_External.
1374 Added access control facility by interfacing the TCP wrapper library.
1375 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1376 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1377 name of the daemon and enables the access control as specified in
1378 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1380 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1381 den Dool <H.M.vdnDool@kub.nl>.
1383 Added reference ID parameter to most functions in server API - refer
1384 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1386 Changed name of ccl library to libccl.a (was ccl.a).
1388 Fixed bug in decoder for Explain (Category TargetInfo).
1390 Added support for GNU readline in client. Thanks to Jacob Poulsen
1391 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1393 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1394 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1395 IMPLEMENTATION! This change was made to the development version before
1396 the ZIG decided to retract the amendment. If any users MUST be
1397 compatible with the original Update definition, PLEASE CONTACT US, and
1398 we will include a separate definition corresponding to the old Update
1399 ES. Note that because of the change to the ASN.1 of the
1400 TaskPackageRecordStructure we cannot define a single structure that
1401 will support both versions.
1403 * Added const modifier to buffer parameter for some ODR/BER encoding
1404 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1405 completeWAIS, odr_dumpBER.
1407 Fixed bug in client.c which caused a crash when a scanResponse didn't
1408 contain positionOfTerm.
1410 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1411 * will cause an error in a client if a non-YAZ target sends both a
1412 * list of Scan entries and non-surrogate diagnostics.
1414 Retrieval module enhancements. Tag sets may be typed in the reference
1415 to it. From the .abs-file the "tagset" directive takes a third optional
1416 integer type for the tag set referenced. From a .tag-file the "include"
1417 directive takes a third optional type as well. The old "type" directive
1418 in the tag set itself is still recognized but acts as the default type
1421 Backend interface change. Individual Scan terms returned from bend_scan
1422 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1423 in include/backend.h.
1425 Retrieval module enhancements. Multiple tag sets and attribute sets may
1426 be specified in abstract syntax specs. Revised the error/warning for
1427 logging messages reported by the retrieval module when reading the
1430 Object Identifier system (oid_..) changed. The API is backwards
1431 compatible but the oid-routines now allocates new OID's when needed.
1432 Raw OID's may be specified in oid_getvalbyname.
1434 YAZ now uses GNU configure to generate Makefile(s).
1436 * Minor changes in some of the member names of DeleteResultSetRequest and
1437 DeleteResultSetResponse. See include/proto.h.
1439 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1440 and added member 'languages' in TargetInfo (which was missing).
1442 Changed the way attribute sets are handled in the retrieval
1443 module. These are now cached, just like the abstract syntaxes
1446 Changed YAZ so that it links with compiled ASN.1.
1448 Added Explain-schema definitions and mapping routines. The following
1449 Explain categories have been implemented: AttributeDetails,
1450 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1452 Fixed minor bug in Windows version of Server Library.
1454 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1456 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1458 Added EXTERNAL: UNIverse Resource Report (non-standard).
1460 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1461 ENUMERATED and SET OF.
1463 * Added 'const' to some of the char pointer arguments for the
1464 functions, data1_read_node, data1_getelementbytagname,
1465 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1468 Fixed bug in data1_insert_taggeddata - the last_child member of
1469 parent wasn't initialised.
1471 * Changed data1_read_record and data1_read_node so that the supplied
1472 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1473 doesn't refer to any parts of the "SGML"-buffer.
1475 Fixed bug in server library (Windows version of statserv_remove).
1477 * Changed code so that it compiles as C++. The type definition
1478 of Odr_fun which is a member of Odr_arm was changed. The result is,
1479 that an explicit typecast is needed for the fun pointer when
1480 using Odr_arm - as in:
1481 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1483 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1485 Implemented the new structured date and time definition as approved
1486 by the ZIG. Added schemaId element to the specificTag in Espec-1
1487 (also approved at the last ZIG). Thanks to RVDM.
1489 Added some Object identifiers (RVDM).
1491 Changed the Update Extended Service (RVDM).
1493 Added command "refid" to client which specifies referenceId for
1494 the following requests.
1496 Implemented extended service handling for server. See ztest.c
1497 for an example as well as backend.h. New handlers are registerd
1498 in the Init handler.
1500 * Changed interface for sort in server.
1502 Added new members to statserv_options_block. It allows a server
1503 to read options from another source than just the command line. Thanks
1504 to Charles Woodfield.
1506 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1507 renamed to zboolean. Some C++ compilers complained about the name.
1509 Minor changes to gils.abs. Added index 's' (sort) on title
1510 and date/time-last-modified.
1512 --- 1.4pl2 1998/1/30
1514 Fixed bug in server library regarding inetd mode (-i). This bug
1515 was introduced by release 1.4.
1517 --- 1.4pl1 1998/1/29
1519 Added sort facility in client and backend server interface.
1521 Fixed problem with dependencies in Makefile(s).
1523 Fixed bugs for encoders/decoders of extended services and
1526 Implemented sub-tree feature for schemas. Sub-trees are
1527 referenced in *.abs-files. See explain.abs for an example
1528 of the use of this feature.
1530 Modified bib1.att; local attributes for ANY didn't include
1531 ANY itself (only affects use of the retrieval module).
1533 Fixed bug in plain SGML reader in function data1_read_node:
1534 tags with prefix "var" was incorrectly interpreted as variants.
1536 Added feature "sub-schemas" to enable references to - and definitions
1537 of - group of elements.
1539 * Removed member parent from type data1_element (in data1.h).
1541 Implemented function odr_nullval() that returns the value of
1544 * Removed member num_children from data1_node (in data1.h).
1546 Made NT service interface part of the server library. The
1547 function statserv_main uses the NT service when required and
1548 calls the statserv_start / statserv_close routines.
1550 Routine zget_SearchRequest and zget_PresentRequest fills
1551 resultSetName/Id member with "default" instead of "Default".
1553 Fixed memory leak in server. Request queue member wasn't freed.
1555 Fixed nmem_exit so that memory is freed.
1559 Revised the CCL parser utility to be thread safe.
1561 Added function, oid_ent_to_oid, to replace the function
1562 oid_getoidbyent, which is not thread safe.
1564 * Added nmem_init and nmem_exit to initialize and release
1565 NMEM resources. Function nmem_init should be called once in the
1566 initial thread before NMEM/ODR is used. statserv.c and client.c
1567 have been changed accordingly. The change was necessary to make
1568 NMEM thread safe. The NMEM memory pool is shared amongst threads
1569 in a process. Unix-based applications will still work fine without
1572 Added NT Services interface for the the Z39.50 (statserv) Server.
1573 Refer to the ztest.c source on the usage.
1575 Windows 95/NT port using MSVC5.0. Project files are included in the
1578 * Defined new 'global' handle for the retrieval (data1) system. The
1579 new handled, data1_handle, describes the state of the data1 system.
1580 This handle is passed as first argument to virtually all
1581 data1 related routines. The functions data1_create and data1_destroy
1582 creates and destroys a data1 handle respectively.
1584 Added ODR encode stream member to all backend request structures
1585 init, search, scan etc. This stream should be used to allocate all
1586 memory used for the response when thread safe operation is needed.
1588 Changed the comstack utility, cs_addstr, to be thread safe. The
1589 returned hostname string returned by the function is now part the
1592 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1593 function. The cs_straddr takes a COMSTACK handle as argument, so this
1594 function must be used after cs_create and before bind/connect.
1595 This function is thread safe.
1597 Moved test server to 'ztest' directory - generic server code still
1598 in 'server' directory.
1600 Made prefix query (pquery.c) utility thread safe.
1602 Added new function modifier YAZ_EXPORT to 'export' public DLL
1603 functions when using windows (see include/yconfig.h).
1605 Added definitions to the OID database (util/oid.c) (RVDM).
1607 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1609 Added call to ccl_rpn_delete in client program.
1611 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1612 release of RPN structure.
1614 Added support for C++, headers uses extern "C" for public definitions.
1615 With input from RVDM.
1617 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1618 Thanks to Ronald van der Meer (RVDM).
1620 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1622 Added support for private extensions to the OID database
1623 (oid_setprivateoids()). Thanks to RVDM.
1625 Added optional, physical ANY (key replication)
1627 Fixed null-reference problem in GRS-1 output filter.
1629 Proximity operator added to Prefix Query Format (PQF).
1631 In test client command "base" accepts multiple databases.
1633 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1637 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1639 Smallish bug-fixes in the new encoders/decoders (explain).
1641 Bug fixed in DeleteRequest.
1643 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1645 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1647 Added SOIF syntax (using private OID for now) to retrieval module and client.
1649 Added Update extended service.
1651 Added SearchResult-1 additional info structure.
1653 Added optional CCL (ISO8777) interpreter as separate module. Available
1656 --- 1.2 1996/6/10 (1st anniversary release)
1658 Added Summary record syntax. Lightly tested.
1660 Added OPAC record syntax. Untested.
1662 Added ResourceReport service encoders/decoders. Untested.
1664 Fixed bug in z_Unit - wrong tagging on unitSystem.
1666 Fixed bug in the DiagRecs decoder.
1668 Added options for max PDU size and session timeout to frontend-server.
1670 Added documentation of query-language parsers and other supporting utilities.
1672 [frontend-server] Added Attribute set to the bend_scanrequest API.
1674 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1675 surrogate diagnostics were generated.
1677 [retrieval] Allow multiple local values for attribute.
1679 [retrieval] Allow multiple attributes per element in .abs files. index type.
1681 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1683 --- 1.1pl2 1996/4/10
1685 Minor changes, mostly specific to Zebra's requirements (retrieval)
1689 Repaired bug in frontend server when running multiple listening
1690 endpoints in dynamic mode.
1692 z_External() now won't break if a known, ASN.1 value comes encapsulated
1693 in an octet-string. The value will pass through unmodified in an Odr_oct.
1695 Added a bit of code to the demo client to decode & display
1696 ASN.1-structured records represented in the octet-aligned branch of
1697 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1699 Added z_ext_getentbyref() to the ASN module. Doc updated.
1701 * Completed the SCAN definition in the ASN module. This may break SCAN
1702 code based on older YAZ-versions at compile-time. The fix is easy -
1705 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1706 under the SCAN definition. Remember to initialize this, server-people.
1708 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1709 that this does not extend to ODR and ASN.
1711 Comstack allows insertion of established socket (primarily for
1712 inetd-operation of servers). Doc updated.
1714 Front-end server can now start from the inetd in TCP mode. Doc
1717 --- 1.0pl4 1996/1/24
1721 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1722 the rank and record number.
1724 Adjustments to the frontend server.
1726 Fixed diagnostic BER dumper. It ignored the file argument.
1730 Various changes to retrieval module.
1732 Changed the union discriminators of the protocol files from enums to
1733 ints paired with #defines.
1735 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1738 *Changed operator in the RPN structure to 'roperator', again to avoid a
1741 Fixed problems in Explain decoders/encoders.
1743 --- 1.0pl2 1995/12/6
1745 Memory bug in log module fixed.
1747 --- 1.0pl1 1995/12/5
1749 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1751 Bug in Explain DatabaseInfo module fixed.
1753 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1757 The shift to v1.0 signals that we now consider the *core* functionality
1758 of YAZ reasonably stable (the core being more or less equivalent to
1759 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1760 tested (Explain not at all - though that will happen soonish).
1762 Minor changes to code to support Windows port.
1764 Various minor changes after we're getting to use GRS-1 & co. more.
1766 Added Espec-1 format.
1768 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1769 of the protocol and it cannot be selected when encoding (maps into 'string'
1770 when decoding). Needed to talk to some servers.
1772 Demo client can request simple element set names.
1774 Added Diagnostic Format encoders/decoders.
1776 Added simple Close handling to frontend server (no hooks for resource
1777 reporting yet), and demonstration client.
1779 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1781 --- 1.0b3 1995/08/24
1783 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1784 handled incorrectly when records were requested in the searchResponse. This
1785 will only affect you if you use the frontend-server.
1787 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1788 Test-client will ask for and print GRS1. Ztest will return dummy records
1791 Added Explain encoders/decoders to the service-level API. Untested.
1793 Added Extended Services: Item Order encoders and decoders to the Service-
1794 level API. Untested. We could use a recent copy of the pertinent bits
1795 of the ILL protocol to add those bits.
1797 Added diagnostic format 1 encoders/decoders to the service-level API.
1800 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1801 odr_cons.c, which causes a more correct output.
1803 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1804 was always set to 0 when no records were requested in the searchRequest.
1806 * Added better external-handling. This shouldn't harm old code that
1807 *encodes* externals. It can break code that looks for a
1808 'single-ASN1-type' representation, since those types that are known
1809 are now decoded immediately. Look at the SUTRS sample code in
1810 seshigh.c and client.c. Documentation updated.
1812 Handling of structured records in bend_fetchresponse. Length -1 marks
1813 structured record, type is deduced from format field.
1815 --- 1.0b2 1995/06/27
1816 Fairly quick maintenance release to add SUTRS support.
1818 Fixed handling of SUTRS records in the demonstration client.
1820 * Added format field to the bend_fetchrequest and bend_fetchresponce
1821 structures of the backend API (frontend server). When the record is
1822 returned, the value of the format field is mapped to an OID. The
1823 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1824 of the record. The special value VAL_NONE in the bend_request means
1825 that no specific format was requested by the client. Documentation
1826 updated accordingly. Test server (ztest) will return a fixed dummy
1827 SUTRS record if your client requests SUTRS.
1829 Documentation updated accordingly.
1831 You can now set external libraries and RANLIB support in the top-level
1835 First public release.
