1 Implemented yaz_filepath_comp which splits a path into file path
2 components (required by Zebra 2.0.3+).
4 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
5 BSD inspired license until now so this should not have any real impact on
6 anybody. See http://www.opensource.org/licenses/bsd-license.php
8 Fixed bug #687: Missing log lines.
10 Fixed bug #678: CQL to PQF translation does not preserve double-quote
13 Fixed bug #689: SRU diagnostics to be added.
15 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
16 whether a connection is idle (no more work do do).
20 Change type of optval from long to int for invocation of setsockopt with
21 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
23 Added support for specifying the max log file size for the Generic
24 Frontend Server. The size is given with option -r.
28 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
32 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
35 Fixed bug in Generic Frontend Server that could cause a server to stop
36 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
38 For the generic frontend server, the maximum record size is used as maximum
39 size of incoming packages (SRU + Z39.50). The value until was previously
40 only used in Z39.50 Init negotiation and, later, in a session controlled
41 sizes of records returned. This is controlled using -k option. It can be
42 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
46 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
49 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
51 New option for yaz-marcdump -lpos=value which allows setting a portion
52 of MARC header to a certain value.
54 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
56 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
57 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
61 Fixed problem with SRU mode type (soap, get, post) for yaz-client
64 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
68 Fixed MARC ISO2709 encoding routines to deal with character set
71 Minor changes to GFS logging. Database included in search request log
74 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
75 cached/multiple records.
77 Shared libraries are built by default on Unix+configure.
79 Changed cql2pqf transformation to use a different evaluation order. The
80 new order is: always, relation, structure, position, truncation, index
81 and relationModifier. Old order was: always, relation, relationModifier,
82 structure, index, position, truncation. Note that the the latter ones
83 override former ones for identical attributes.. The new scheme means that
84 it is possible to override any existing attribute with a relationModifier.
85 And also that it is possible to override everything for the index rule
86 (except the ones listed in relationModifier). No order is perfect but this
87 one, we believe, covers more real cases.. The "always" should have been
88 called "default", since the attributes there can be overridden with all
91 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
92 compilation phase, but also for yaz-config --cflags output. This allows
93 us to have public headers with Libxml2 stuff in them . It should also,
94 eventually, make Libxml2 checks redundant in packages using YAZ, such
99 Changed SRU update structure bend_update_rr so that SRU diagnostics are
100 stored in uri, message and details.. Previously diagnostics were stored
101 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
102 compatibility.. but he's probably the only one affected, so.
104 Added support for CCL, compiled on the client side, in ZOOM-C. This
105 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
106 input; the resulting query objects can be used for for searching with
107 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
109 YAZ' configure searches for OpenSSL by default.
111 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
112 SL_CTX_use_certificate_file. See
113 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
114 for more info. Thanks to Ko van der Sloot.
116 --- 2.1.20 2006/06/02
118 Bug #600: SRU GET, POST support for yaz-client. Introduced
119 command 'sru' which selects method SOAP/GET/POST.
121 Allow missingValueAction to be specified for the sortspec string -
122 function yaz_sort_spec. By default, the missing value action is null.
123 Use ! to specify "abort". Use = followed by stringvalue to specify default
126 Ensured that Present-handler (if defined) is called in GFS before any call to
127 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
128 searchRetrieve requests.
130 Documentation for YAZ is now based on the Docbook XML/XSLT using
131 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
132 is no longer depending on jade/openjade or docbook-to-man scripts.
133 PDF is no longer part of the distribution - but can optionally be
134 made using DSSSL/jadetex or FOP.
136 Added retrieval handling support in Generic Frontend Server to support
137 conversion between MARC/XML as well as XSLTtransforms. See
138 etc/yazgfs.xml for an example.
140 Added Authentication support to Generic Frontend Server in SRU
141 mode. Authentication using HTTP Basic is supported, as is the use
142 of 'x-username' and 'x-password' parameters in the request itself.
144 Added support for a new character set MARC8s identical to MARC8 except
145 that it converts combined characters to single Unicode characters in the
146 Latin-1 range (when possible).
148 --- 2.1.18 2006/04/24
150 ASN.1 compiler 0.4: generates brief Doxygen file header for
151 generated .h/.c files.
153 Utility yaz_iconv now supports conversion to MARC-8.
155 New facilities for the MARC module. The reading - and writing of
156 content are separate methods for the yaz_marc_t handle. The following
157 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
158 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
159 format). Write functions have prefix yaz_marc_write_.. The existing
160 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
161 available. Removed support for OAI-MARC and simplexml (not the
162 simplexml from PHP5).
164 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
165 to be returned for this connection.
167 --- 2.1.16 2006/03/31
169 Allow multiple languages and charsets to be specified with
170 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
171 negcharset iso-8859-1,utf-8
173 Translation of proximity nodes from CQL into PQF now works.
175 Moved to automake 1.8, 1.9.
177 Added function yaz_log_set_handler which allows a log handler to be
178 installed. This handler will be called for all log messages. Output
179 to file is also produced; but that can be disabled by passing NULL
180 fname to yaz_log_init_file.
182 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
184 For SRW (including GFS), accept application/soap+xml as content-type
187 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
188 produces NO stylesheet reference even if a default stylesheet is specified
191 --- 2.1.14 2006/03/14
193 Updated Windows package to include yazd.dll + yazd.lib for the
194 Development component.
196 If the environment variable YAZ_LOG is set, then it is used as a
197 string indicating the default level of logging to use if not
198 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
199 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
200 used as before. So, for example, to omit warnings from YAZ logging,
203 cql_transform() now map structure and other attributes before indexes,
204 so that index-specific structures and other attributes can override
205 defaults. So now a combination of mapping specifications such as:
207 index.dc.date = 1=date-modified 4=5
208 does the right thing.
210 cql_transform() now also respects the "always" mapping specification,
211 which establishes an initial set of attributes to be used for all
212 terms except where overridden by more specific attributes associated
213 with the index, relation or modifier.
215 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
216 which mode to use; one of "post", "get" or "soap" (SRW, default).
218 Fixes for yaz_iconv routines: changed trie-based character set conversions
219 to use only non-negative values for bit fields due to Sun's C compiler not
220 supporting negative values.
222 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
223 sequences where not read correctly. Fix by Rustam Usmanov.
225 Updated win/makefile to use options, settings which makes things
226 compile with VS C 2005.
228 --- 2.1.12 2006/02/01
230 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
232 In ZOOM socket code, use select instead of poll on MacOSX.
234 ZOOM-C now support client-side compilation of CQL into RPN that is
235 sent to the server, enabling CQL to be used against all Z39.50
236 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
237 ZOOM_query object, and submit it using ZOOM_connection_search().
238 The CQL-to-RPN translation uses a configuration file, the name of
239 which must be specified in the Connection's "cqlfile" option.
241 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
242 function, which takes as its start-term parameter a ZOOM_query object
243 (which may have had either CQL or RPN set into it).
246 --- 2.1.10 2005/11/29
248 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
249 GFS to support this as well. Backend handler, bend_srw_update, does the
250 update work. Code contributed by Ko van der Sloot.
252 Allow retrieval of Search Result-1 information in ZOOM by the use of
253 options that are attached to a result set. ZOOM documentation updated
256 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
257 UTF-8 conversion. Patch by Raj Patel.
259 Added option -m to GFS to control formatting of timestamps in log file.
261 Added 'exit' as synonym for 'quit' in yaz-client
263 Added support for specifying SRW resultSetId + resultSetIdleTime in a
264 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
265 for the new members. Patch by Ko van der Sloot.
267 Added support for SRU POST. It is supported for content-type
268 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
270 Do not build the separate Multi-threaded (MT) library libyazthread.la.
271 Instead make the library libyaz.la multi-threaded. Threading as a whole
272 can still be disabled by configure option --disable-threads. Previosly,
273 with older GLIBCs there were problems with MT libs under Apache. This
274 has now been fixed a long time ago.
276 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
279 CQL module modified to be case insensitive for relations/indexes/operations.
281 Fixed bug in CQL transform code: incorrect value relationModifieder
284 Added 'show all' command for yaz-client which retrieves all results
287 Added new yaz-client, xmles, which takes a (private) OID and
288 a document to be sent as an extended service request.
290 Describe new yaz-client commands wait_response and set_auto_wait.
292 Increase TCP/IP listener backlog from 3 (which I am guessing was
293 copied from the SunOS manual entry way back when) so SOMAXCONN, so
294 that the socket will queue as many incoming connections as it's able
295 to handle ongoing connections. In other words, it will never now
296 refuse a connection that it would be able to handle merely because
297 it's not got around to accepting() enough of the pending connections
298 yet. This is the behaviour anyway under Linux, where the listen()
299 argument is ignored; but not under BSD and on systems such as
300 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
301 YAZ-based servers should now be uniform across operating systems in
304 yaz-marcdump uses 64-bit file access on some systems. This is enabled
305 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
306 This allows yaz-marcdump to read large MARC batches (>2 GB).
308 Modified all YAZ source files - except the source which is auto-generated
309 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
312 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
313 corresponding to the existing *_setl() function. These allow option
314 values containing arbitrary valuues.
316 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
317 ZOOM_resultset_sort() in new applications. Its behaviour is identical
318 except that it returns an indicator of whether or not the sort
319 criterion was accepted (0 for OK, -1 for invalid).
323 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
324 MARC output rather than returning "new" buffer.
326 yaz-client warns about unknown init options.
328 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
332 Added support for SRW sort in Generic Frontend Server. Patch
333 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
334 sortKeys - or NULL if none is provided.
336 Fixed bug #307: It was impossible to specify indefinite/no timeout
337 for ZOOM_event. Special timeout value -1 now means indefinite timeout
340 Added support for multiple languages and charsets to be specified in
341 ZOOM. Each charset/language is separated by a blank. If negotiation is
342 in effect in init-response, Option
343 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
344 Code based on patch by Vasiliy Osadchuk.
346 Fixed bug #306: infinite recursion that occurred when calling
347 yaz_log_level_init as the first call (before other log level or
350 Fixed bug in scan handling in front end server: if preferred-Position-In-
351 Response was non-present, a NULL pointer referece was performed.
355 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
356 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
357 now defined for all those error codes. So instead of putting 109 in
358 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
359 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
361 Modified the yaz-marcdump utility to skip garbage bytes between MARC
364 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
366 Program yaz-client now exits and produces an error message if multiple
367 Z39.50 servers are specified on the command line (none or one allowed
370 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
375 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
377 Fixed bug #272: Preserve spacing for CCL terms.
381 Added support for virtual hosts and multiple backend servers for
382 the YAZ frontend server. The configution is XML based and
383 support specificition of CQL to RPN mappings and explain information.
384 See section "Virtual Hosts" in the YAZ manual.
386 Extended OPAC display utility. OPAC display utility renders
387 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
388 to supplement yaz_marc_decode_wrbuf.
390 Fixed a bug in MARC decoder that could caused it to crash for some
391 invalid MARC records. More diagnostics and warnings where added in
392 XML output (warnings, etc are stored in comments).
394 --- 2.0.34 2005/02/08
396 Fixes for UNIX domain sockets. Bug #261.
398 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
400 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
401 Added yaz_marc_subfield_str which defines subfield lead string which is
402 used in YAZ_MARC_LINE format. Default string is blank+$. Added
403 yaz_marc_endline_str which defines end of fields string used in
404 YAZ_MARC_LINE format. Default string is newline.
406 Experimental support for MarcXChange. This format can be produced
407 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
408 http://www.bs.dk/standards/MarcXchange.xsd
410 Added yaz-client commands scansize that sets maximum number of
411 entries to be returned by scan.
413 --- 2.0.32 2005/01/11
415 Added support for SRW scan in yaz-client and Generic Frontend Server.
417 * Added whereInList member to SRW Scan Term.
419 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
421 Fixed NMEM system to return aligned blocks on the smallest boundaries
422 that are suitably aligned for all possible types on the particular
423 architecture YAZ is being built for.
425 --- 2.0.30 2005/01/04
427 Fixed numerious warnings that was issued with newer versions of GCC.
429 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
430 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
433 Make YAZ Generic Frontend Server slightly faster.
435 Enhance (and reduce) logging for Generic Frontend Server.
437 Revert YAZ log system so that it flushes every write operation
438 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
440 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
441 instead of LOG_, due to name clash with syslog(3). LOG_ are still
442 present. New applications should define YAZ_USE_NEW_LOG=1 - this
443 will effectively disable old definitions.
445 --- 2.0.28 2004/11/09
447 Added yaz_log_time_format which specifies log format using
450 Added yaz_log_module_level which returns mask for a module. Value
451 is non-zero mask a if module is enabled; zero if disabled.
453 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
454 in include/yaz/cql.h.
456 Fixed bug #176: Dont throw diagnostics on empty SRU args.
458 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
460 Fixed bug #172: RPM builds does not enable SSL.
462 Doxyfile.in part of dist. Doxyfile generated by configure.
464 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
465 are given and the corresponding component does not exist.
467 Extend CCL documentation in YAZ reference. Describe r=r.
469 --- 2.0.26 2004/10/01
471 Fixed MARC->MARCXML conversion to properly deal with
472 fields, subfields, indicators having non-ASCII characters.
474 Fixed MARC->MARCXML conversion so that ASCII control characters
475 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
478 Added YAZ GFS support for conversion from Z39.50 surrogate
479 diagnostics to SRW surrogate diagnostics.
481 Bug fix: YAZ GFS did not return schema in explainResponse.
483 --- 2.0.25 2004/09/30
485 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
486 now converts recordSchema to elementSetName as well as schema URI.
488 Fixed bug in COMSTACK that prevented HTTP request packages from being
491 --- 2.0.24 2004/09/29
493 Added CCL facility r=r "range" which is similar to r=o "ordered" but
494 does not require white-space before and after the dash in a range, e.g.
495 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
498 Fixed a few AC_TRY_LINK configure tests that did not operate properly
499 due to new GCC removing "redundant" code.
501 Added yaz-client commands scanpos and scanstep that sets preferred
502 position and step-size for scan.
504 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
506 Added CCL utility ccl_qual_buf which parses one or more CCL
507 spec lines in a buffer.
509 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
510 of name and value - ignoring empty lines and comments.
512 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
514 Added odr_get_element_path which returns current element path for an
515 ODR handle. This utility is useful in error handling or user-defined
518 Added ODR_PRINT utility odr_set_stream which is is a more generic
519 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
520 to a write function and pointer to close function. The close function - if
521 non-NULL - will be called during odr_destroy.
523 Fixed bug in CCL parser where truncation char was not removed from
524 right side when truncation=both was in effect.
526 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
529 --- 2.0.23 2004/08/11
531 Fix buffer overrun in CQL parser when dealing with proximity (%).
533 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
534 to UTF-8/UCS conversion is now only based on codetables.xml.
536 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
538 --- 2.0.22 2004/08/06
540 Add support for more "commit changes" in ZOOM (uses Extended Services).
542 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
545 Yet another small fix for configure of SSL.
547 --- 2.0.21 2004/05/14
549 Fix SSL libs for configure when --with-openssl=DIR is given.
551 --- 2.0.20 2004/05/10
553 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
555 SSL comstack now uses yaz.pem certificate file on server side
556 by default. Certificate filename can be configured by calling
557 comstack function cs_set_ssl_certificate_file before cs_bind is used.
559 Fix bug regarding multiple calls to ZOOM_connection_connect.
561 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
563 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
564 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
566 ZOOM now allows inspection of X509 peer certificate for verification.
567 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
569 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
570 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
571 as "modular" but it simplifies things.
573 Added cs_get_peer_certificate to that returns peer X509 PEM.
575 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
576 NULL if SSL is unavailable.
578 Documentation about MARC decoding tools.
580 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
582 --- 2.0.19 2004/03/30
584 Rename CHANGELOG to NEWS to follow GNU style packing.
586 Fix bug with missing initialization of member in init_diagnostics.
587 This bug affects threaded version of GFS server.
589 --- 2.0.18 2004/03/20
591 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
594 Ensure zlib.dll is packed with Windows install.
596 --- 2.0.17 2004/03/17
598 Fix encoding of xsd:string to use text instead of CDATA.
600 Fix endless loop in CQL parser with unbalanced ".
602 Use a more compact way to store MARC-8 conversion tables.
604 --- 2.0.16 2004/03/16 Debian only
606 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
609 Update CQL parser to use new CQL 1.1 modifiers for booleans and
614 --- 2.0.15 2004/03/01
616 Another fix for decoding of XML packed records.
618 --- 2.0.14 2004/02/25
620 Fixes for Chunked encoding. White space not ignored after length spec.
622 Update NS and use default NS for SRW diagnostic elements.
624 --- 2.0.13 2004/02/23
626 Implement ZOOM_resultset_cache_reset which resets record cache.
628 Implement ZOOM_resultset_sort which sorts a result set.
630 Implement chunked HTTP transfer.
632 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
634 --- 2.0.12 2004/02/16
636 Added member 'schema' to bend_explain_rr structure so that backend
637 can specify explain record identifier. Defaults to Zeerex 2.0.
639 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
641 --- 2.0.11 2004/02/16
643 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
646 Added init command for yaz-client which sends "extra" init request.
648 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
649 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
651 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
653 Make ZOOM error code for "invalid query".
655 Fixed compilation for SSL which wasn't properly enabled for all platforms.
657 --- 2.0.10 2004/02/05
659 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
662 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
664 Added option -p <file> to make Generic Frontend Server to write PID file.
666 Added option -D to put Generic Frontend Server in background on its own.
668 Make ZOOM C recognize option "password". If unset, "pass" is used
669 (for backwards compatibility).
671 Fixed a bug in Generic Frontend Server that could make it crash if a
672 client sets characterSetNegotation bit, but didn't pass negotiation stuff
675 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
676 Must be issued before open, in order to be in effect.
678 --- 2.0.9-6 2004/01/12 Debian/Windows
680 Make the SRU server more picky WRT unknown params, etc.
682 Bug fix: ZOOM scan response didn't return displayTerm - when present.
684 New YAZ client command, options, that sets Z39.50 options.
686 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
687 options from a string of tokens (one token for each option bit).
689 Update SRW diagnostic code messages.
691 --- 2.0.9-5 2004/01/07 Debian/Windows
693 Handle user defined stylesheet for SRW/SRU.
695 --- 2.0.9-4 2004/01/06 Debian/Windows
697 Fix bug in decoding of Content-Length.
699 --- 2.0.9-3 2004/01/06 Debian/Windows
701 Fix a bug with decoding of XML packed records.
703 --- 2.0.9-2 2004/01/05 Debian only
705 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
707 Fix bug in SRW/SRU diagnostics decoding.
711 Fixed bug in Generic Frontend Server which could drop records exceeding
712 preferred message size. Reported and fixed by Irina Dijour.
714 Fixed calculation of package size for structured records in Generic
715 Frontend Server. Reported and fixed by Irina Dijour.
717 Fixed namespace for SRW/SRU diagnostics.
719 Fixed SEGV in yaz-client that occured for HTTP connection errors.
723 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
724 this version is incompatible with version 1.0 and older YAZ SRW/SRU
727 CQL changes to reflect recent changes to the specification:
728 * Documentation talks about context sets instead of index sets.
729 * Documentation talks about indexes instead of qualifiers.
730 * The CQL-to-PQF transformer's configuration file now uses
731 "index.set.name = <attributes>" instead of the old form
732 "qualifier.set.name = <attributes>". (Both forms are still
733 understood but the latter is deprecated.)
734 * CQL terms with no explicit index specified are now interpreted as
735 cql.serverChoice instead of srw.serverChoice (which of course
736 behaves exactly the same.)
740 MARC conversion can now generate ISO2709 output in another
741 character set. yaz-marcdump uses this facility if you invoke it
744 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
745 functions from there can be used from C++.
749 Frontend server now transfers memory from decoded packages to stream
752 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
753 references to show up.
755 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
756 the ZOOM Abstract API. The older names for the same options are still
757 also supported for the benefit of old applications.
759 ZOOM-C supports "implementationId" and "implementationVersion" options
760 to go along with "implementationName". These allow the user code to
761 specify identification strings to be sent to servers.
762 Add OID for the new ExtLite attribute set.
764 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
765 as requested/supplid by Ere Maijala <ere@atp.fi>
767 For generic frontend server, reverse the order of
768 "toolkit-supplied / application-supplied" strings sent as implementationId,
769 Name and Version. Also, remove the spaces around the slash. This brings
770 the GFS in line with the behaviour of ZOOM-C on the client side.
772 Add function ZOOM_scanset_display_term.
774 yaz-client shows scan displayTerm if present.
776 Utility yaz-iconv is now installed by default along with the man page
779 Extend configure check for OpenSSL to use pkg-config where available (such
782 Incorporate patch by Morten Bogeskov which allows a Unix file socket
783 server to specify uid/gid/mask for socket using the format
784 unix:[user=uid,][group=gid,][umask=mask,]file=path
785 If file= is omitted the existing format is assumed, e.g.
787 in which case the mask is 0666 (rw for everybody).
789 Major restructure of YAZ source. All source in libyaz is in src directory.
790 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
791 util (utility programs such as ASN.1 compiler, yaz-marcdump).
793 Added man page for utility yaz-marcdump (used to be called marcdump).
794 yaz-marcdump is installed by 'make install'.
796 Fixed a memory leak in Generic Frontend Server that occurred when decoding
797 of incoming package failed.
799 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
801 Change prototype of odr_perror: add const to message string.
803 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
805 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
806 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
807 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
808 DNS lookup. There should not be any compatibility problems with this
809 assuming that blocking=1 or 0 is used.
811 Fix bad reference in UNIX comstack in function cs_addrstr.
813 Fix for compilation on AIX.
815 The generic front-end server (server/seshigh.c) now supports returning
816 Init diagnostics to the client in User-information-field, in
817 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
822 Allow any CQL relation (not just all,any,exact,scr).
824 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
825 that features the same UI.
827 Implemented command update0 in YAZ client which is equivalent to
828 update but uses old of Ext Update ASN.1.
830 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
831 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
832 Previously no OID was used for this info.
834 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
835 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
836 returns 'malformed search term' otherwise.
838 SortResponse member resultCount now set to NULL in sort handler of
841 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
844 Add three new utility functions for translating OIDs between various
845 formats -- symbolic name such as "Usmarc", minus-1-terminated int
846 arrays and dotted strings such as "1.2.840.10003.9.5.1":
847 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
848 char *oid_to_dotstring(const int *oid, char *oidbuf);
849 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
851 Reverted modifications for ES Update definition for z_IU0Update
852 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
853 is back to YAZ 2.0.2.
855 String value attributes for CCL parser.
857 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
858 which their FirstSearch server returns in Init responses, sometimes
859 carrying useful diagnostic information when Init fails. This has the
860 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
861 "z39.50/oclcui.asn", where its definition is somewhat different from
862 what OCLC document on their web-site, as required to interoperate with
865 Support for anonymous authentication in yaz-client. Use the command
868 * Fix the OID of the Index Data-local "admin" Extended Service from
869 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
870 the 1000, which indicates a locally-defined OID, was a mistake.
874 Fix CCL directive @case handling so that it affects string match for
875 both CCL keywords and qualifiers.
877 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
878 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
879 Decoder has been updated with ASN.1 changes as listed in
880 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
881 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
882 z_IUUpdate, remains unchanged.
884 ZOOM_record_get may now return a record in a specific character set.
885 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
886 "from" is the character set of record as returned by target. "to" is
887 the character set to be returned. If omitted, "to" is UTF-8.
889 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
891 New ODR utility, odr_getelement, which returns name of element for
892 which encoding/decoding failed.
894 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
895 in cases where a required element was omitted.
897 Bug fix: some MARC8 sequences were not converted.
899 New ZOOM option "step" which specifies number of records to be
900 retrieved in one chunk. Used in conjunction with "start" and "count".
902 SRW support for yaz-client. Use scheme http: to use it, e.g.
905 yaz-client no longer does (un)intelligent character set conversions
906 by default. Can be enabled with charset and marc_charset commands.
908 xmalloc trace fix for 64-bit systems such as DEC alpha.
910 Solaris 2.6 compile fix.
912 New function, cql_strerror() translates SRW error codes, as returned
913 by cql_transform_error(), into human-readable English strings. Used
914 in yaz-client diagnostics when appropriate.
916 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
917 converts it into a type-1 query which is sent to the server. This
918 makes CQL available for use with all Z-servers, as opposed to the tiny
919 minority that can handle CQL queries themselves.
923 New Debian package layout similar to the Redhat Package layout.
925 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
926 and search result respectively.
930 Redhat package is now several packages: libyaz (runtime libraries),
931 libyaz-devel (development and documentation, and yaz (utility programs).
932 Package spec file by Morten Bøgeskov.
934 New member 'schema' in struct bend_fetch_rr which the name of requested
935 schema (SRW/SRU) for record (or NULL if none was given). The fetch
936 handler MAY set this to reflect the schema of the returned record.
938 New member 'display_term' in struct scan_entry. GFS now sets member entries
939 and allocates scan entries to be filled by user scan handler. In previous
940 version, entries member was allocated by the scan handler. That still works,
941 but the GFS will ignore member display_term - assuming it was NOT set by
942 the handler. The fact that the GFS now allocates the entries both allows
943 for new members and makes a scan handler easier to write.
945 Fix CQL lex buffer overflow.
947 SRW/SRU recordPacking. For SRW default recordPacking is string. For
948 SRU default recordPacking is string.
950 SRU protocol support for frontend server.
952 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
954 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
956 Added scan for the ZOOM shell (zoomsh).
960 * String Identifers for Schemas (Amendment 5).
961 http://lcweb.loc.gov/z3950/agency/amend/am5.html
962 Old definition for schema
963 Odr_oid *schema; /* OPT */
968 Z_InternationalString *uri;
969 #define Z_Schema_oid 1
970 #define Z_Schema_uri 2
973 * resultCount parameter to Sort Response (Amendment 1).
974 http://lcweb.loc.gov/z3950/agency/amend/am1.html
976 Support for SRW 1.0 over HTTP. This is an optional feature and
977 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
980 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
981 on the same port. SRW SearchRetrieveRequests are mapped
982 to bend_init,bend_search,bend_fetch,bend_close.
984 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
986 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
987 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
989 ZOOM connections are SRW based if schem http is used for hostname
990 in connect, e.g. z = ZOOM_connection_new("http://myserver");
991 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
993 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
994 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
995 distance=n, order=true/false, relation=le, prox unit=word. If
996 n is omitted, distance 1 is used.
998 Fixed problem with C compiler include path in wrong order.
1000 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1001 on Solaris. Patch from Ko van der Sloot.
1003 New MARC decode API. All new functions operate on a yaz_marc_t
1004 handle. The most important new functions are: yaz_marc_create,
1005 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1006 decode and destroy respectively. Decoder can produce formats
1007 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1008 include/yaz/marcdisp.h.
1010 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1011 to UTF-8, UCS-32, wchar_t or Latin-1.
1013 * Prototypes for yaz_iconv_-functions moved to separate header
1014 include/yaz/yaz-iconv.h.
1016 Make a few private functions 'static' in unix.c. This prevents
1017 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1019 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1020 are set when Init Response is received.
1022 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1023 but returns diagnostic set as well.
1025 New function yaz_strerror which is a portable wrapper for
1026 strerror/strerror_r/GetLastMessage.
1028 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1029 is returned for MARC. If type is "oai", then OAI MARC is returned.
1031 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1034 --- 1.9.2 2002/11/26
1036 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1038 Fix bad race conditions on SIGTERM and terminate gracefully in
1041 Move retrieval (data1) module to Zebra since nobody seems to be
1044 Add GRS-1 render for ZOOM using same format as yaz-client.
1046 --- 1.9.1 2002/10/05
1048 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1050 Fix broken ESpec handling in data1 module.
1052 SGML reader parses comments and makes them part of the data1 tree.
1054 Added several type casts so that YAZ compiles as C++ code.
1056 ZOOM didn't handle PDU encoding failures properly.
1058 Added more Bib-1 diagnostics (approved extensions).
1060 GNU configure: better check for iconv.
1062 More portable use of accept, getpeername. Check for socklen_t. Use
1063 int/size_t if socklen_t is not defined.
1067 PQF parser rejects bad queries - including those with extra
1068 characters in them. PQF parser used to silently ignore that.
1069 Cleaner API for PQF added, which allows you to get detailed
1070 error information for bad queries (see yaz/pquery.h).
1072 Fixed bug in ZOOM_record_get for type "database".
1074 Implemented mini iconv library supporting conversions between
1075 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1077 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1079 --- 1.8.9 2002/08/20
1081 Fixed ZOOM C record cache so that preferredRecordSyntax and
1082 elementSetName is used to check for already fetched records.
1084 --- 1.8.8 2002/08/02
1086 Added three members in bend_initrequest structure to facilitate
1087 character set negotiation.
1089 Fixed a bug in frontend server that could cause indefinite
1090 loops under rare conditions.
1092 Revised character set utilities (charneg.h) so that encoding
1093 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1095 For PQF, directive @term <type> sets term type for Scan/Search.
1096 Here <type> is general, string, numeric, null. The term type
1097 is inherited - just like @attr.
1099 New call odr_set_charset that sets character set conversion for
1100 international-strings on a ODR stream. Prototype is:
1101 int odr_set_charset(ODR o, const char *to, const char *from);
1102 The InternationalString is still represented as C string in YAZ
1103 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1104 won't). On the protocol level, you can use any encoding.
1106 Support for UNIX sockets in ZOOM.
1108 Solaris recv sometimes returns errno == ENOENT. It is treated as
1109 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1111 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1112 both client and server. Code by Morten Bøgeskov.
1114 --- 1.8.7 2002/05/22
1116 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1117 that they can be used directly from Visual Basic. You must recompile
1118 your windows APP if you're using ZOOM.
1120 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1121 Commands "lang" and "charset" sets language and character set respectively.
1122 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1123 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1125 Attributes from multiple CCL fields may be OR'ed rather than merged
1126 using directive "@field or". Fields are still merged by default -
1127 equivalent to "@field merge".
1129 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1132 Fixed bug in zget for parameter ExtendedServicesResponse.
1136 --- 1.8.6 2002/03/25
1138 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1140 Client displays USR.1:SearchResult-1 (hits per term).
1142 Additional Search Info for search in Generic Frontend Server.
1144 Fixed CCL parsing of "field=s".
1146 WIN32 installer - using the excellent NSIS software from nullsoft.
1148 Fixed CCL parsing of "field = - <number>".
1150 Added function yaz_marc_decode that decodes MARC for line mode
1151 display or XML (similar to that used by JZKit).
1153 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1154 Z39.50. But ISO/ILL was, however.
1156 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1157 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1159 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1160 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1162 --- 1.8.5 2002/02/03
1164 New YAZ client features: Command completion and new commands:
1165 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1166 Code provided by Jacob Poulsen.
1168 New call oid_trav, that visits all registered OIDs via callback.
1170 Function ZOOM_record_get now returns const char pointer rather than
1171 void pointer. It saves a lot of type casts.
1173 For YAZ client, command "auth" now allows you to set authentication
1174 in IdPass style. It is enabled when three tokens are given - order
1175 is user, group and password.
1177 Fix memory leaks in MARC record handling for ZOOM.
1179 New option for YAZ client, -k <kilobytes> that sets
1180 maximum record size. Similar to -k option for generic frontend
1181 server and yaz-ztest.
1183 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1185 Prefix query parser reports "fail" when bad attribute set is given.
1187 Fix in MARC decoder. Proximity logging. Fix for attribute set
1188 in scan handler for server. Patches by Shigeru Ishida.
1190 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1193 Configure option --with-openssl=<dir> now works when a directory is
1194 specified. Patch provided by Morten Bøgeskov.
1196 New option for YAZ client, -u <auth>, that sets authentication.
1198 ZOOM fix: error information was sometimes "missing", since error
1199 was cleared/reset too when it shouldn't.
1201 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1203 --- 1.8.4 2002/01/04
1205 Scan for ZOOM API. New object ZOOM_scanset. New functions
1206 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1207 ZOOM_scanset_destroy.
1209 New ZOOM function, ZOOM_connection_last_event, that returns type
1210 of last event (such as "receive data", "send data", "apdu received",
1213 New ZOOM option, schema, that specifies schema for retrieval.
1215 New CCL feature. Qualifiers can be aliases for one or more
1216 other qualifiers (if more than one is given, OR is used).
1218 ZOOM uses named result sets if target supports it.
1220 Two new YAZ client commands: . (dot, which sources a script of YAZ
1221 client commands), and ! (to execute shell command.). Implemented
1224 Working on Debian packages.
1226 --- 1.8.3 2001/11/19
1228 YAZ client enables named result sets only if target supports it.
1230 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1232 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1233 with key="host" to get same result.
1235 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1236 Function Z3950_resultset_record(s) returns references to records
1237 "owned" by resultset. To become owner use Z3950_record_clone.
1239 Function z_ext_record handles Extended Services. Thanks to
1242 --- 1.8.2 2001/11/12
1244 CCL Parser fix: ignore token comma when dealing with and-lists.
1246 Documentation updates for COMSTACK.
1248 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1249 Changed prototype Z3950_records. For some functions, int parameters
1250 were changed to size_t.
1252 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1255 New MARC decode/display function, marc_display_exl, which properly rejects
1256 non-ISO2709 records. YAZ client uses it.
1258 --- 1.8.1 2001/10/29
1260 Fix bug: local attribute set wasn't set correctly in PQF strings.
1264 * Old Z39.50 codecs no longer supported.
1266 Added ZOOM C binding. See http://zoom.z3950.org/
1268 Renamed states for COMSTACKs to avoid confusion with events.
1270 Implemented cs_look and proper cs_rcvconnect.
1272 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1274 Configure detects POSIX threads on OpenBSD.
1276 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1277 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1279 When error is returned from present handler, non-surrogate diagnostic
1280 is returned in present response (and fetch handler is no longer called).
1282 * Minor adjustments to pquery parser (PQF). Token characters may be
1283 escaped by using backslash (C-style).
1285 PQF parser allows string attribute values to be specified. For @attr,
1286 non-numeric characters after the equal-sign are treated as strings
1287 (e.g. @attr 9=title).
1289 CCL trunction character may be defined (@truncation in file)
1291 * function zget_ExtendedServicesRequest sets waitAction to
1292 waitIfPossible (was wait).
1294 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1297 CCL operator names may be set in field definition files (CCL_bibset).
1298 See ccl/bib1 for an example.
1300 Fixes in ASN.1 compiler for C++ compatibility.
1302 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1303 and "op_or" to avoid conflict with C++.
1305 Fixed problem with GNU readline detection on Redhat 7.0.
1307 Added step-size for Scan backend handler.
1309 Fixed bug that made the frontend server crash when no attribute
1310 set was specified for scan.
1312 Front-end server automatically switches to original working directory
1313 when installed as an NT service. Previously -w had to be specified to
1316 Added extended attributes for retrieval module (data1), so that data1
1317 records carry d1_readXML/SGML attributes. d1_read also supports
1318 null-data rules ( <tag/>)
1320 On UNIX when POSIX threads are available, a separate library libyazthread
1321 is created. Programmers should link with that library and the yaz library
1322 when using threads. The reason for the split was that some applications
1323 on Linux, such as Apache, doesn't work well when using shared objects that
1326 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1327 (or any frontend server) in SSL mode by specifying ssl: followed by
1328 address. Only tested on UNIX.
1330 Added feature for CCL module. Virtual structure s=al or s=ol generates
1331 and-list and or-list respectively instead of phrase search.
1335 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1336 log_mask_str. This was done to avoid name conflicts with other libraries
1337 (such as other PHP extensions).
1339 Added raw OID member for preferred record syntax (request_format_raw)
1340 and returned record syntax (output_format_raw) for backend fetch method.
1342 Config file yaz-config now accepts options so that it returns specific
1343 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1345 Shared library support for UNIX using GNU libtool.
1347 * Modified backend interface. Request/Response struct's replaced by
1348 one read/write C struct. For example bend_fetchrequest and
1349 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1350 Every handler - even search has to be registered in bend_init
1351 handler. This means that the YAZ library no longer refers to
1352 external functions and it makes it possible to make the whole
1353 thing a single DLL/SO.
1355 Added Segment handler for backend server.
1357 Added Zmbol/Zebra administrative functions to YAZ client.
1359 Threaded frontend server on UNIX (when POSIX Threads are available).
1360 Starting the server with option -T enables multi-threading.
1364 Added configure option --enable-comp/disable-comp to control use
1365 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1366 located in sub directory asn.
1368 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1369 in ${exec_prefix}/bin along with the other programs yaz-client and
1372 GNU automake used to maintain makefiles.
1374 Added several OID's.
1376 Changed retrieval module so that we can load records with no abstract
1377 syntax defined. Tagpaths in these records are fully composed of string
1380 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1384 On UNIX, the generated makefile now supports a proper 'make install'.
1385 The prefix can be set via GNU configure to set the install location
1386 (default is /usr/local).
1388 * YAZ programs client and ztest were renamed to yaz-client and
1389 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1390 locations, such as /usr/bin,/usr/local/bin,etc.
1392 * YAZ Header files were moved from include to include/yaz. YAZ Header
1393 files are referred to as include <yaz/log.h> rather than <log.h>.
1394 The YAZ include path (-I ..) is therefore the same as before. Programmers
1395 should update their #include statements or use -Ipath/include/yaz
1396 instead. The main motivation for doing this change is that YAZ header files
1397 can be installed in "standard" locations /usr/include,/usr/local/include
1398 without introducing conflicts, since ALL YAZ header files are stored
1399 in subdirectory yaz (under /usr/include for example).
1401 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1402 rather than project/workspace files. We switched because project files
1403 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1406 Changed name of logging function, logf, to yaz_log, to prevent name
1407 clash with some math-log functions. The YAZ header log.h defines logf
1408 to yaz_log (#define) so there should be no incompatibilities by this
1411 Added bend_start/bend_stop handlers for server. These handler are
1412 called on start/stop of server. For windows they are called whenever
1413 a service is started/stopped.
1415 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1416 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1417 in util/yc.tcl. The auto-generated C code structures are, in a few
1418 cases, incompatible with the old decoders. There are differences in the
1419 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1420 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1421 The preprocessor variable ASN_COMPILED is defined when the compiled
1422 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1423 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1424 wish to use the old encoders/decoders you can specify --disable-yc
1427 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1428 version so that it supports both new - and old version of DB Update
1430 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1431 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1432 change. The name parameter can be set to 0 in which no name is specified
1433 for the construction. The macros odr_implicit and odr_explicit sets name
1434 parameter to zero for the construction involved. New macros
1435 odr_implicit_tag and odr_explicit_tag are similar to the others,
1436 except that a name parameter is added. For programmers' that don't use
1437 ODR they probably only need to change the call to z_APDU and z_External.
1439 Added access control facility by interfacing the TCP wrapper library.
1440 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1441 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1442 name of the daemon and enables the access control as specified in
1443 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1445 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1446 den Dool <H.M.vdnDool@kub.nl>.
1448 Added reference ID parameter to most functions in server API - refer
1449 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1451 Changed name of ccl library to libccl.a (was ccl.a).
1453 Fixed bug in decoder for Explain (Category TargetInfo).
1455 Added support for GNU readline in client. Thanks to Jacob Poulsen
1456 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1458 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1459 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1460 IMPLEMENTATION! This change was made to the development version before
1461 the ZIG decided to retract the amendment. If any users MUST be
1462 compatible with the original Update definition, PLEASE CONTACT US, and
1463 we will include a separate definition corresponding to the old Update
1464 ES. Note that because of the change to the ASN.1 of the
1465 TaskPackageRecordStructure we cannot define a single structure that
1466 will support both versions.
1468 * Added const modifier to buffer parameter for some ODR/BER encoding
1469 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1470 completeWAIS, odr_dumpBER.
1472 Fixed bug in client.c which caused a crash when a scanResponse didn't
1473 contain positionOfTerm.
1475 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1476 * will cause an error in a client if a non-YAZ target sends both a
1477 * list of Scan entries and non-surrogate diagnostics.
1479 Retrieval module enhancements. Tag sets may be typed in the reference
1480 to it. From the .abs-file the "tagset" directive takes a third optional
1481 integer type for the tag set referenced. From a .tag-file the "include"
1482 directive takes a third optional type as well. The old "type" directive
1483 in the tag set itself is still recognized but acts as the default type
1486 Backend interface change. Individual Scan terms returned from bend_scan
1487 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1488 in include/backend.h.
1490 Retrieval module enhancements. Multiple tag sets and attribute sets may
1491 be specified in abstract syntax specs. Revised the error/warning for
1492 logging messages reported by the retrieval module when reading the
1495 Object Identifier system (oid_..) changed. The API is backwards
1496 compatible but the oid-routines now allocates new OID's when needed.
1497 Raw OID's may be specified in oid_getvalbyname.
1499 YAZ now uses GNU configure to generate Makefile(s).
1501 * Minor changes in some of the member names of DeleteResultSetRequest and
1502 DeleteResultSetResponse. See include/proto.h.
1504 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1505 and added member 'languages' in TargetInfo (which was missing).
1507 Changed the way attribute sets are handled in the retrieval
1508 module. These are now cached, just like the abstract syntaxes
1511 Changed YAZ so that it links with compiled ASN.1.
1513 Added Explain-schema definitions and mapping routines. The following
1514 Explain categories have been implemented: AttributeDetails,
1515 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1517 Fixed minor bug in Windows version of Server Library.
1519 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1521 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1523 Added EXTERNAL: UNIverse Resource Report (non-standard).
1525 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1526 ENUMERATED and SET OF.
1528 * Added 'const' to some of the char pointer arguments for the
1529 functions, data1_read_node, data1_getelementbytagname,
1530 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1533 Fixed bug in data1_insert_taggeddata - the last_child member of
1534 parent wasn't initialised.
1536 * Changed data1_read_record and data1_read_node so that the supplied
1537 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1538 doesn't refer to any parts of the "SGML"-buffer.
1540 Fixed bug in server library (Windows version of statserv_remove).
1542 * Changed code so that it compiles as C++. The type definition
1543 of Odr_fun which is a member of Odr_arm was changed. The result is,
1544 that an explicit typecast is needed for the fun pointer when
1545 using Odr_arm - as in:
1546 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1548 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1550 Implemented the new structured date and time definition as approved
1551 by the ZIG. Added schemaId element to the specificTag in Espec-1
1552 (also approved at the last ZIG). Thanks to RVDM.
1554 Added some Object identifiers (RVDM).
1556 Changed the Update Extended Service (RVDM).
1558 Added command "refid" to client which specifies referenceId for
1559 the following requests.
1561 Implemented extended service handling for server. See ztest.c
1562 for an example as well as backend.h. New handlers are registerd
1563 in the Init handler.
1565 * Changed interface for sort in server.
1567 Added new members to statserv_options_block. It allows a server
1568 to read options from another source than just the command line. Thanks
1569 to Charles Woodfield.
1571 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1572 renamed to zboolean. Some C++ compilers complained about the name.
1574 Minor changes to gils.abs. Added index 's' (sort) on title
1575 and date/time-last-modified.
1577 --- 1.4pl2 1998/1/30
1579 Fixed bug in server library regarding inetd mode (-i). This bug
1580 was introduced by release 1.4.
1582 --- 1.4pl1 1998/1/29
1584 Added sort facility in client and backend server interface.
1586 Fixed problem with dependencies in Makefile(s).
1588 Fixed bugs for encoders/decoders of extended services and
1591 Implemented sub-tree feature for schemas. Sub-trees are
1592 referenced in *.abs-files. See explain.abs for an example
1593 of the use of this feature.
1595 Modified bib1.att; local attributes for ANY didn't include
1596 ANY itself (only affects use of the retrieval module).
1598 Fixed bug in plain SGML reader in function data1_read_node:
1599 tags with prefix "var" was incorrectly interpreted as variants.
1601 Added feature "sub-schemas" to enable references to - and definitions
1602 of - group of elements.
1604 * Removed member parent from type data1_element (in data1.h).
1606 Implemented function odr_nullval() that returns the value of
1609 * Removed member num_children from data1_node (in data1.h).
1611 Made NT service interface part of the server library. The
1612 function statserv_main uses the NT service when required and
1613 calls the statserv_start / statserv_close routines.
1615 Routine zget_SearchRequest and zget_PresentRequest fills
1616 resultSetName/Id member with "default" instead of "Default".
1618 Fixed memory leak in server. Request queue member wasn't freed.
1620 Fixed nmem_exit so that memory is freed.
1624 Revised the CCL parser utility to be thread safe.
1626 Added function, oid_ent_to_oid, to replace the function
1627 oid_getoidbyent, which is not thread safe.
1629 * Added nmem_init and nmem_exit to initialize and release
1630 NMEM resources. Function nmem_init should be called once in the
1631 initial thread before NMEM/ODR is used. statserv.c and client.c
1632 have been changed accordingly. The change was necessary to make
1633 NMEM thread safe. The NMEM memory pool is shared amongst threads
1634 in a process. Unix-based applications will still work fine without
1637 Added NT Services interface for the the Z39.50 (statserv) Server.
1638 Refer to the ztest.c source on the usage.
1640 Windows 95/NT port using MSVC5.0. Project files are included in the
1643 * Defined new 'global' handle for the retrieval (data1) system. The
1644 new handled, data1_handle, describes the state of the data1 system.
1645 This handle is passed as first argument to virtually all
1646 data1 related routines. The functions data1_create and data1_destroy
1647 creates and destroys a data1 handle respectively.
1649 Added ODR encode stream member to all backend request structures
1650 init, search, scan etc. This stream should be used to allocate all
1651 memory used for the response when thread safe operation is needed.
1653 Changed the comstack utility, cs_addstr, to be thread safe. The
1654 returned hostname string returned by the function is now part the
1657 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1658 function. The cs_straddr takes a COMSTACK handle as argument, so this
1659 function must be used after cs_create and before bind/connect.
1660 This function is thread safe.
1662 Moved test server to 'ztest' directory - generic server code still
1663 in 'server' directory.
1665 Made prefix query (pquery.c) utility thread safe.
1667 Added new function modifier YAZ_EXPORT to 'export' public DLL
1668 functions when using windows (see include/yconfig.h).
1670 Added definitions to the OID database (util/oid.c) (RVDM).
1672 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1674 Added call to ccl_rpn_delete in client program.
1676 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1677 release of RPN structure.
1679 Added support for C++, headers uses extern "C" for public definitions.
1680 With input from RVDM.
1682 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1683 Thanks to Ronald van der Meer (RVDM).
1685 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1687 Added support for private extensions to the OID database
1688 (oid_setprivateoids()). Thanks to RVDM.
1690 Added optional, physical ANY (key replication)
1692 Fixed null-reference problem in GRS-1 output filter.
1694 Proximity operator added to Prefix Query Format (PQF).
1696 In test client command "base" accepts multiple databases.
1698 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1702 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1704 Smallish bug-fixes in the new encoders/decoders (explain).
1706 Bug fixed in DeleteRequest.
1708 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1710 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1712 Added SOIF syntax (using private OID for now) to retrieval module and client.
1714 Added Update extended service.
1716 Added SearchResult-1 additional info structure.
1718 Added optional CCL (ISO8777) interpreter as separate module. Available
1721 --- 1.2 1996/6/10 (1st anniversary release)
1723 Added Summary record syntax. Lightly tested.
1725 Added OPAC record syntax. Untested.
1727 Added ResourceReport service encoders/decoders. Untested.
1729 Fixed bug in z_Unit - wrong tagging on unitSystem.
1731 Fixed bug in the DiagRecs decoder.
1733 Added options for max PDU size and session timeout to frontend-server.
1735 Added documentation of query-language parsers and other supporting utilities.
1737 [frontend-server] Added Attribute set to the bend_scanrequest API.
1739 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1740 surrogate diagnostics were generated.
1742 [retrieval] Allow multiple local values for attribute.
1744 [retrieval] Allow multiple attributes per element in .abs files. index type.
1746 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1748 --- 1.1pl2 1996/4/10
1750 Minor changes, mostly specific to Zebra's requirements (retrieval)
1754 Repaired bug in frontend server when running multiple listening
1755 endpoints in dynamic mode.
1757 z_External() now won't break if a known, ASN.1 value comes encapsulated
1758 in an octet-string. The value will pass through unmodified in an Odr_oct.
1760 Added a bit of code to the demo client to decode & display
1761 ASN.1-structured records represented in the octet-aligned branch of
1762 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1764 Added z_ext_getentbyref() to the ASN module. Doc updated.
1766 * Completed the SCAN definition in the ASN module. This may break SCAN
1767 code based on older YAZ-versions at compile-time. The fix is easy -
1770 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1771 under the SCAN definition. Remember to initialize this, server-people.
1773 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1774 that this does not extend to ODR and ASN.
1776 Comstack allows insertion of established socket (primarily for
1777 inetd-operation of servers). Doc updated.
1779 Front-end server can now start from the inetd in TCP mode. Doc
1782 --- 1.0pl4 1996/1/24
1786 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1787 the rank and record number.
1789 Adjustments to the frontend server.
1791 Fixed diagnostic BER dumper. It ignored the file argument.
1795 Various changes to retrieval module.
1797 Changed the union discriminators of the protocol files from enums to
1798 ints paired with #defines.
1800 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1803 *Changed operator in the RPN structure to 'roperator', again to avoid a
1806 Fixed problems in Explain decoders/encoders.
1808 --- 1.0pl2 1995/12/6
1810 Memory bug in log module fixed.
1812 --- 1.0pl1 1995/12/5
1814 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1816 Bug in Explain DatabaseInfo module fixed.
1818 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1822 The shift to v1.0 signals that we now consider the *core* functionality
1823 of YAZ reasonably stable (the core being more or less equivalent to
1824 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1825 tested (Explain not at all - though that will happen soonish).
1827 Minor changes to code to support Windows port.
1829 Various minor changes after we're getting to use GRS-1 & co. more.
1831 Added Espec-1 format.
1833 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1834 of the protocol and it cannot be selected when encoding (maps into 'string'
1835 when decoding). Needed to talk to some servers.
1837 Demo client can request simple element set names.
1839 Added Diagnostic Format encoders/decoders.
1841 Added simple Close handling to frontend server (no hooks for resource
1842 reporting yet), and demonstration client.
1844 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1846 --- 1.0b3 1995/08/24
1848 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1849 handled incorrectly when records were requested in the searchResponse. This
1850 will only affect you if you use the frontend-server.
1852 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1853 Test-client will ask for and print GRS1. Ztest will return dummy records
1856 Added Explain encoders/decoders to the service-level API. Untested.
1858 Added Extended Services: Item Order encoders and decoders to the Service-
1859 level API. Untested. We could use a recent copy of the pertinent bits
1860 of the ILL protocol to add those bits.
1862 Added diagnostic format 1 encoders/decoders to the service-level API.
1865 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1866 odr_cons.c, which causes a more correct output.
1868 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1869 was always set to 0 when no records were requested in the searchRequest.
1871 * Added better external-handling. This shouldn't harm old code that
1872 *encodes* externals. It can break code that looks for a
1873 'single-ASN1-type' representation, since those types that are known
1874 are now decoded immediately. Look at the SUTRS sample code in
1875 seshigh.c and client.c. Documentation updated.
1877 Handling of structured records in bend_fetchresponse. Length -1 marks
1878 structured record, type is deduced from format field.
1880 --- 1.0b2 1995/06/27
1881 Fairly quick maintenance release to add SUTRS support.
1883 Fixed handling of SUTRS records in the demonstration client.
1885 * Added format field to the bend_fetchrequest and bend_fetchresponce
1886 structures of the backend API (frontend server). When the record is
1887 returned, the value of the format field is mapped to an OID. The
1888 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1889 of the record. The special value VAL_NONE in the bend_request means
1890 that no specific format was requested by the client. Documentation
1891 updated accordingly. Test server (ztest) will return a fixed dummy
1892 SUTRS record if your client requests SUTRS.
1894 Documentation updated accordingly.
1896 You can now set external libraries and RANLIB support in the top-level
1900 First public release.
