2 Updates for SRU Update by Ko van der Sloot:
3 1. Changed name from "operation" to "action"
4 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
5 versions in the code, marked as 'backward compatible'.
6 3. Added diagnostics for SRU Update.
8 Fixd bug #709: Records are fetched in wrong format when tasks are queued.
12 Implemented yaz_filepath_comp which splits a path into file path
13 components (required by Zebra 2.0.3+).
15 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
16 BSD inspired license until now so this should not have any real impact on
17 anybody. See http://www.opensource.org/licenses/bsd-license.php
19 Fixed bug #687: Missing log lines.
21 Fixed bug #678: CQL to PQF translation does not preserve double-quote
24 Fixed bug #689: SRU diagnostics to be added.
26 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
27 whether a connection is idle (no more work do do).
31 Change type of optval from long to int for invocation of setsockopt with
32 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
34 Added support for specifying the max log file size for the Generic
35 Frontend Server. The size is given with option -r.
39 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
43 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
46 Fixed bug in Generic Frontend Server that could cause a server to stop
47 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
49 For the generic frontend server, the maximum record size is used as maximum
50 size of incoming packages (SRU + Z39.50). The value until was previously
51 only used in Z39.50 Init negotiation and, later, in a session controlled
52 sizes of records returned. This is controlled using -k option. It can be
53 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
57 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
60 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
62 New option for yaz-marcdump -lpos=value which allows setting a portion
63 of MARC header to a certain value.
65 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
67 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
68 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
72 Fixed problem with SRU mode type (soap, get, post) for yaz-client
75 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
79 Fixed MARC ISO2709 encoding routines to deal with character set
82 Minor changes to GFS logging. Database included in search request log
85 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
86 cached/multiple records.
88 Shared libraries are built by default on Unix+configure.
90 Changed cql2pqf transformation to use a different evaluation order. The
91 new order is: always, relation, structure, position, truncation, index
92 and relationModifier. Old order was: always, relation, relationModifier,
93 structure, index, position, truncation. Note that the the latter ones
94 override former ones for identical attributes.. The new scheme means that
95 it is possible to override any existing attribute with a relationModifier.
96 And also that it is possible to override everything for the index rule
97 (except the ones listed in relationModifier). No order is perfect but this
98 one, we believe, covers more real cases.. The "always" should have been
99 called "default", since the attributes there can be overridden with all
102 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
103 compilation phase, but also for yaz-config --cflags output. This allows
104 us to have public headers with Libxml2 stuff in them . It should also,
105 eventually, make Libxml2 checks redundant in packages using YAZ, such
108 --- 2.1.22 2006/06/15
110 Changed SRU update structure bend_update_rr so that SRU diagnostics are
111 stored in uri, message and details.. Previously diagnostics were stored
112 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
113 compatibility.. but he's probably the only one affected, so.
115 Added support for CCL, compiled on the client side, in ZOOM-C. This
116 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
117 input; the resulting query objects can be used for for searching with
118 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
120 YAZ' configure searches for OpenSSL by default.
122 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
123 SL_CTX_use_certificate_file. See
124 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
125 for more info. Thanks to Ko van der Sloot.
127 --- 2.1.20 2006/06/02
129 Bug #600: SRU GET, POST support for yaz-client. Introduced
130 command 'sru' which selects method SOAP/GET/POST.
132 Allow missingValueAction to be specified for the sortspec string -
133 function yaz_sort_spec. By default, the missing value action is null.
134 Use ! to specify "abort". Use = followed by stringvalue to specify default
137 Ensured that Present-handler (if defined) is called in GFS before any call to
138 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
139 searchRetrieve requests.
141 Documentation for YAZ is now based on the Docbook XML/XSLT using
142 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
143 is no longer depending on jade/openjade or docbook-to-man scripts.
144 PDF is no longer part of the distribution - but can optionally be
145 made using DSSSL/jadetex or FOP.
147 Added retrieval handling support in Generic Frontend Server to support
148 conversion between MARC/XML as well as XSLTtransforms. See
149 etc/yazgfs.xml for an example.
151 Added Authentication support to Generic Frontend Server in SRU
152 mode. Authentication using HTTP Basic is supported, as is the use
153 of 'x-username' and 'x-password' parameters in the request itself.
155 Added support for a new character set MARC8s identical to MARC8 except
156 that it converts combined characters to single Unicode characters in the
157 Latin-1 range (when possible).
159 --- 2.1.18 2006/04/24
161 ASN.1 compiler 0.4: generates brief Doxygen file header for
162 generated .h/.c files.
164 Utility yaz_iconv now supports conversion to MARC-8.
166 New facilities for the MARC module. The reading - and writing of
167 content are separate methods for the yaz_marc_t handle. The following
168 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
169 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
170 format). Write functions have prefix yaz_marc_write_.. The existing
171 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
172 available. Removed support for OAI-MARC and simplexml (not the
173 simplexml from PHP5).
175 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
176 to be returned for this connection.
178 --- 2.1.16 2006/03/31
180 Allow multiple languages and charsets to be specified with
181 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
182 negcharset iso-8859-1,utf-8
184 Translation of proximity nodes from CQL into PQF now works.
186 Moved to automake 1.8, 1.9.
188 Added function yaz_log_set_handler which allows a log handler to be
189 installed. This handler will be called for all log messages. Output
190 to file is also produced; but that can be disabled by passing NULL
191 fname to yaz_log_init_file.
193 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
195 For SRW (including GFS), accept application/soap+xml as content-type
198 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
199 produces NO stylesheet reference even if a default stylesheet is specified
202 --- 2.1.14 2006/03/14
204 Updated Windows package to include yazd.dll + yazd.lib for the
205 Development component.
207 If the environment variable YAZ_LOG is set, then it is used as a
208 string indicating the default level of logging to use if not
209 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
210 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
211 used as before. So, for example, to omit warnings from YAZ logging,
214 cql_transform() now map structure and other attributes before indexes,
215 so that index-specific structures and other attributes can override
216 defaults. So now a combination of mapping specifications such as:
218 index.dc.date = 1=date-modified 4=5
219 does the right thing.
221 cql_transform() now also respects the "always" mapping specification,
222 which establishes an initial set of attributes to be used for all
223 terms except where overridden by more specific attributes associated
224 with the index, relation or modifier.
226 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
227 which mode to use; one of "post", "get" or "soap" (SRW, default).
229 Fixes for yaz_iconv routines: changed trie-based character set conversions
230 to use only non-negative values for bit fields due to Sun's C compiler not
231 supporting negative values.
233 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
234 sequences where not read correctly. Fix by Rustam Usmanov.
236 Updated win/makefile to use options, settings which makes things
237 compile with VS C 2005.
239 --- 2.1.12 2006/02/01
241 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
243 In ZOOM socket code, use select instead of poll on MacOSX.
245 ZOOM-C now support client-side compilation of CQL into RPN that is
246 sent to the server, enabling CQL to be used against all Z39.50
247 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
248 ZOOM_query object, and submit it using ZOOM_connection_search().
249 The CQL-to-RPN translation uses a configuration file, the name of
250 which must be specified in the Connection's "cqlfile" option.
252 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
253 function, which takes as its start-term parameter a ZOOM_query object
254 (which may have had either CQL or RPN set into it).
257 --- 2.1.10 2005/11/29
259 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
260 GFS to support this as well. Backend handler, bend_srw_update, does the
261 update work. Code contributed by Ko van der Sloot.
263 Allow retrieval of Search Result-1 information in ZOOM by the use of
264 options that are attached to a result set. ZOOM documentation updated
267 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
268 UTF-8 conversion. Patch by Raj Patel.
270 Added option -m to GFS to control formatting of timestamps in log file.
272 Added 'exit' as synonym for 'quit' in yaz-client
274 Added support for specifying SRW resultSetId + resultSetIdleTime in a
275 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
276 for the new members. Patch by Ko van der Sloot.
278 Added support for SRU POST. It is supported for content-type
279 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
281 Do not build the separate Multi-threaded (MT) library libyazthread.la.
282 Instead make the library libyaz.la multi-threaded. Threading as a whole
283 can still be disabled by configure option --disable-threads. Previosly,
284 with older GLIBCs there were problems with MT libs under Apache. This
285 has now been fixed a long time ago.
287 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
290 CQL module modified to be case insensitive for relations/indexes/operations.
292 Fixed bug in CQL transform code: incorrect value relationModifieder
295 Added 'show all' command for yaz-client which retrieves all results
298 Added new yaz-client, xmles, which takes a (private) OID and
299 a document to be sent as an extended service request.
301 Describe new yaz-client commands wait_response and set_auto_wait.
303 Increase TCP/IP listener backlog from 3 (which I am guessing was
304 copied from the SunOS manual entry way back when) so SOMAXCONN, so
305 that the socket will queue as many incoming connections as it's able
306 to handle ongoing connections. In other words, it will never now
307 refuse a connection that it would be able to handle merely because
308 it's not got around to accepting() enough of the pending connections
309 yet. This is the behaviour anyway under Linux, where the listen()
310 argument is ignored; but not under BSD and on systems such as
311 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
312 YAZ-based servers should now be uniform across operating systems in
315 yaz-marcdump uses 64-bit file access on some systems. This is enabled
316 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
317 This allows yaz-marcdump to read large MARC batches (>2 GB).
319 Modified all YAZ source files - except the source which is auto-generated
320 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
323 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
324 corresponding to the existing *_setl() function. These allow option
325 values containing arbitrary valuues.
327 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
328 ZOOM_resultset_sort() in new applications. Its behaviour is identical
329 except that it returns an indicator of whether or not the sort
330 criterion was accepted (0 for OK, -1 for invalid).
334 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
335 MARC output rather than returning "new" buffer.
337 yaz-client warns about unknown init options.
339 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
343 Added support for SRW sort in Generic Frontend Server. Patch
344 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
345 sortKeys - or NULL if none is provided.
347 Fixed bug #307: It was impossible to specify indefinite/no timeout
348 for ZOOM_event. Special timeout value -1 now means indefinite timeout
351 Added support for multiple languages and charsets to be specified in
352 ZOOM. Each charset/language is separated by a blank. If negotiation is
353 in effect in init-response, Option
354 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
355 Code based on patch by Vasiliy Osadchuk.
357 Fixed bug #306: infinite recursion that occurred when calling
358 yaz_log_level_init as the first call (before other log level or
361 Fixed bug in scan handling in front end server: if preferred-Position-In-
362 Response was non-present, a NULL pointer referece was performed.
366 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
367 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
368 now defined for all those error codes. So instead of putting 109 in
369 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
370 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
372 Modified the yaz-marcdump utility to skip garbage bytes between MARC
375 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
377 Program yaz-client now exits and produces an error message if multiple
378 Z39.50 servers are specified on the command line (none or one allowed
381 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
386 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
388 Fixed bug #272: Preserve spacing for CCL terms.
392 Added support for virtual hosts and multiple backend servers for
393 the YAZ frontend server. The configution is XML based and
394 support specificition of CQL to RPN mappings and explain information.
395 See section "Virtual Hosts" in the YAZ manual.
397 Extended OPAC display utility. OPAC display utility renders
398 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
399 to supplement yaz_marc_decode_wrbuf.
401 Fixed a bug in MARC decoder that could caused it to crash for some
402 invalid MARC records. More diagnostics and warnings where added in
403 XML output (warnings, etc are stored in comments).
405 --- 2.0.34 2005/02/08
407 Fixes for UNIX domain sockets. Bug #261.
409 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
411 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
412 Added yaz_marc_subfield_str which defines subfield lead string which is
413 used in YAZ_MARC_LINE format. Default string is blank+$. Added
414 yaz_marc_endline_str which defines end of fields string used in
415 YAZ_MARC_LINE format. Default string is newline.
417 Experimental support for MarcXChange. This format can be produced
418 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
419 http://www.bs.dk/standards/MarcXchange.xsd
421 Added yaz-client commands scansize that sets maximum number of
422 entries to be returned by scan.
424 --- 2.0.32 2005/01/11
426 Added support for SRW scan in yaz-client and Generic Frontend Server.
428 * Added whereInList member to SRW Scan Term.
430 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
432 Fixed NMEM system to return aligned blocks on the smallest boundaries
433 that are suitably aligned for all possible types on the particular
434 architecture YAZ is being built for.
436 --- 2.0.30 2005/01/04
438 Fixed numerious warnings that was issued with newer versions of GCC.
440 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
441 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
444 Make YAZ Generic Frontend Server slightly faster.
446 Enhance (and reduce) logging for Generic Frontend Server.
448 Revert YAZ log system so that it flushes every write operation
449 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
451 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
452 instead of LOG_, due to name clash with syslog(3). LOG_ are still
453 present. New applications should define YAZ_USE_NEW_LOG=1 - this
454 will effectively disable old definitions.
456 --- 2.0.28 2004/11/09
458 Added yaz_log_time_format which specifies log format using
461 Added yaz_log_module_level which returns mask for a module. Value
462 is non-zero mask a if module is enabled; zero if disabled.
464 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
465 in include/yaz/cql.h.
467 Fixed bug #176: Dont throw diagnostics on empty SRU args.
469 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
471 Fixed bug #172: RPM builds does not enable SSL.
473 Doxyfile.in part of dist. Doxyfile generated by configure.
475 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
476 are given and the corresponding component does not exist.
478 Extend CCL documentation in YAZ reference. Describe r=r.
480 --- 2.0.26 2004/10/01
482 Fixed MARC->MARCXML conversion to properly deal with
483 fields, subfields, indicators having non-ASCII characters.
485 Fixed MARC->MARCXML conversion so that ASCII control characters
486 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
489 Added YAZ GFS support for conversion from Z39.50 surrogate
490 diagnostics to SRW surrogate diagnostics.
492 Bug fix: YAZ GFS did not return schema in explainResponse.
494 --- 2.0.25 2004/09/30
496 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
497 now converts recordSchema to elementSetName as well as schema URI.
499 Fixed bug in COMSTACK that prevented HTTP request packages from being
502 --- 2.0.24 2004/09/29
504 Added CCL facility r=r "range" which is similar to r=o "ordered" but
505 does not require white-space before and after the dash in a range, e.g.
506 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
509 Fixed a few AC_TRY_LINK configure tests that did not operate properly
510 due to new GCC removing "redundant" code.
512 Added yaz-client commands scanpos and scanstep that sets preferred
513 position and step-size for scan.
515 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
517 Added CCL utility ccl_qual_buf which parses one or more CCL
518 spec lines in a buffer.
520 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
521 of name and value - ignoring empty lines and comments.
523 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
525 Added odr_get_element_path which returns current element path for an
526 ODR handle. This utility is useful in error handling or user-defined
529 Added ODR_PRINT utility odr_set_stream which is is a more generic
530 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
531 to a write function and pointer to close function. The close function - if
532 non-NULL - will be called during odr_destroy.
534 Fixed bug in CCL parser where truncation char was not removed from
535 right side when truncation=both was in effect.
537 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
540 --- 2.0.23 2004/08/11
542 Fix buffer overrun in CQL parser when dealing with proximity (%).
544 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
545 to UTF-8/UCS conversion is now only based on codetables.xml.
547 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
549 --- 2.0.22 2004/08/06
551 Add support for more "commit changes" in ZOOM (uses Extended Services).
553 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
556 Yet another small fix for configure of SSL.
558 --- 2.0.21 2004/05/14
560 Fix SSL libs for configure when --with-openssl=DIR is given.
562 --- 2.0.20 2004/05/10
564 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
566 SSL comstack now uses yaz.pem certificate file on server side
567 by default. Certificate filename can be configured by calling
568 comstack function cs_set_ssl_certificate_file before cs_bind is used.
570 Fix bug regarding multiple calls to ZOOM_connection_connect.
572 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
574 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
575 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
577 ZOOM now allows inspection of X509 peer certificate for verification.
578 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
580 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
581 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
582 as "modular" but it simplifies things.
584 Added cs_get_peer_certificate to that returns peer X509 PEM.
586 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
587 NULL if SSL is unavailable.
589 Documentation about MARC decoding tools.
591 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
593 --- 2.0.19 2004/03/30
595 Rename CHANGELOG to NEWS to follow GNU style packing.
597 Fix bug with missing initialization of member in init_diagnostics.
598 This bug affects threaded version of GFS server.
600 --- 2.0.18 2004/03/20
602 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
605 Ensure zlib.dll is packed with Windows install.
607 --- 2.0.17 2004/03/17
609 Fix encoding of xsd:string to use text instead of CDATA.
611 Fix endless loop in CQL parser with unbalanced ".
613 Use a more compact way to store MARC-8 conversion tables.
615 --- 2.0.16 2004/03/16 Debian only
617 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
620 Update CQL parser to use new CQL 1.1 modifiers for booleans and
625 --- 2.0.15 2004/03/01
627 Another fix for decoding of XML packed records.
629 --- 2.0.14 2004/02/25
631 Fixes for Chunked encoding. White space not ignored after length spec.
633 Update NS and use default NS for SRW diagnostic elements.
635 --- 2.0.13 2004/02/23
637 Implement ZOOM_resultset_cache_reset which resets record cache.
639 Implement ZOOM_resultset_sort which sorts a result set.
641 Implement chunked HTTP transfer.
643 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
645 --- 2.0.12 2004/02/16
647 Added member 'schema' to bend_explain_rr structure so that backend
648 can specify explain record identifier. Defaults to Zeerex 2.0.
650 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
652 --- 2.0.11 2004/02/16
654 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
657 Added init command for yaz-client which sends "extra" init request.
659 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
660 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
662 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
664 Make ZOOM error code for "invalid query".
666 Fixed compilation for SSL which wasn't properly enabled for all platforms.
668 --- 2.0.10 2004/02/05
670 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
673 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
675 Added option -p <file> to make Generic Frontend Server to write PID file.
677 Added option -D to put Generic Frontend Server in background on its own.
679 Make ZOOM C recognize option "password". If unset, "pass" is used
680 (for backwards compatibility).
682 Fixed a bug in Generic Frontend Server that could make it crash if a
683 client sets characterSetNegotation bit, but didn't pass negotiation stuff
686 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
687 Must be issued before open, in order to be in effect.
689 --- 2.0.9-6 2004/01/12 Debian/Windows
691 Make the SRU server more picky WRT unknown params, etc.
693 Bug fix: ZOOM scan response didn't return displayTerm - when present.
695 New YAZ client command, options, that sets Z39.50 options.
697 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
698 options from a string of tokens (one token for each option bit).
700 Update SRW diagnostic code messages.
702 --- 2.0.9-5 2004/01/07 Debian/Windows
704 Handle user defined stylesheet for SRW/SRU.
706 --- 2.0.9-4 2004/01/06 Debian/Windows
708 Fix bug in decoding of Content-Length.
710 --- 2.0.9-3 2004/01/06 Debian/Windows
712 Fix a bug with decoding of XML packed records.
714 --- 2.0.9-2 2004/01/05 Debian only
716 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
718 Fix bug in SRW/SRU diagnostics decoding.
722 Fixed bug in Generic Frontend Server which could drop records exceeding
723 preferred message size. Reported and fixed by Irina Dijour.
725 Fixed calculation of package size for structured records in Generic
726 Frontend Server. Reported and fixed by Irina Dijour.
728 Fixed namespace for SRW/SRU diagnostics.
730 Fixed SEGV in yaz-client that occured for HTTP connection errors.
734 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
735 this version is incompatible with version 1.0 and older YAZ SRW/SRU
738 CQL changes to reflect recent changes to the specification:
739 * Documentation talks about context sets instead of index sets.
740 * Documentation talks about indexes instead of qualifiers.
741 * The CQL-to-PQF transformer's configuration file now uses
742 "index.set.name = <attributes>" instead of the old form
743 "qualifier.set.name = <attributes>". (Both forms are still
744 understood but the latter is deprecated.)
745 * CQL terms with no explicit index specified are now interpreted as
746 cql.serverChoice instead of srw.serverChoice (which of course
747 behaves exactly the same.)
751 MARC conversion can now generate ISO2709 output in another
752 character set. yaz-marcdump uses this facility if you invoke it
755 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
756 functions from there can be used from C++.
760 Frontend server now transfers memory from decoded packages to stream
763 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
764 references to show up.
766 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
767 the ZOOM Abstract API. The older names for the same options are still
768 also supported for the benefit of old applications.
770 ZOOM-C supports "implementationId" and "implementationVersion" options
771 to go along with "implementationName". These allow the user code to
772 specify identification strings to be sent to servers.
773 Add OID for the new ExtLite attribute set.
775 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
776 as requested/supplid by Ere Maijala <ere@atp.fi>
778 For generic frontend server, reverse the order of
779 "toolkit-supplied / application-supplied" strings sent as implementationId,
780 Name and Version. Also, remove the spaces around the slash. This brings
781 the GFS in line with the behaviour of ZOOM-C on the client side.
783 Add function ZOOM_scanset_display_term.
785 yaz-client shows scan displayTerm if present.
787 Utility yaz-iconv is now installed by default along with the man page
790 Extend configure check for OpenSSL to use pkg-config where available (such
793 Incorporate patch by Morten Bogeskov which allows a Unix file socket
794 server to specify uid/gid/mask for socket using the format
795 unix:[user=uid,][group=gid,][umask=mask,]file=path
796 If file= is omitted the existing format is assumed, e.g.
798 in which case the mask is 0666 (rw for everybody).
800 Major restructure of YAZ source. All source in libyaz is in src directory.
801 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
802 util (utility programs such as ASN.1 compiler, yaz-marcdump).
804 Added man page for utility yaz-marcdump (used to be called marcdump).
805 yaz-marcdump is installed by 'make install'.
807 Fixed a memory leak in Generic Frontend Server that occurred when decoding
808 of incoming package failed.
810 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
812 Change prototype of odr_perror: add const to message string.
814 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
816 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
817 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
818 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
819 DNS lookup. There should not be any compatibility problems with this
820 assuming that blocking=1 or 0 is used.
822 Fix bad reference in UNIX comstack in function cs_addrstr.
824 Fix for compilation on AIX.
826 The generic front-end server (server/seshigh.c) now supports returning
827 Init diagnostics to the client in User-information-field, in
828 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
833 Allow any CQL relation (not just all,any,exact,scr).
835 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
836 that features the same UI.
838 Implemented command update0 in YAZ client which is equivalent to
839 update but uses old of Ext Update ASN.1.
841 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
842 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
843 Previously no OID was used for this info.
845 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
846 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
847 returns 'malformed search term' otherwise.
849 SortResponse member resultCount now set to NULL in sort handler of
852 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
855 Add three new utility functions for translating OIDs between various
856 formats -- symbolic name such as "Usmarc", minus-1-terminated int
857 arrays and dotted strings such as "1.2.840.10003.9.5.1":
858 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
859 char *oid_to_dotstring(const int *oid, char *oidbuf);
860 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
862 Reverted modifications for ES Update definition for z_IU0Update
863 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
864 is back to YAZ 2.0.2.
866 String value attributes for CCL parser.
868 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
869 which their FirstSearch server returns in Init responses, sometimes
870 carrying useful diagnostic information when Init fails. This has the
871 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
872 "z39.50/oclcui.asn", where its definition is somewhat different from
873 what OCLC document on their web-site, as required to interoperate with
876 Support for anonymous authentication in yaz-client. Use the command
879 * Fix the OID of the Index Data-local "admin" Extended Service from
880 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
881 the 1000, which indicates a locally-defined OID, was a mistake.
885 Fix CCL directive @case handling so that it affects string match for
886 both CCL keywords and qualifiers.
888 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
889 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
890 Decoder has been updated with ASN.1 changes as listed in
891 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
892 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
893 z_IUUpdate, remains unchanged.
895 ZOOM_record_get may now return a record in a specific character set.
896 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
897 "from" is the character set of record as returned by target. "to" is
898 the character set to be returned. If omitted, "to" is UTF-8.
900 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
902 New ODR utility, odr_getelement, which returns name of element for
903 which encoding/decoding failed.
905 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
906 in cases where a required element was omitted.
908 Bug fix: some MARC8 sequences were not converted.
910 New ZOOM option "step" which specifies number of records to be
911 retrieved in one chunk. Used in conjunction with "start" and "count".
913 SRW support for yaz-client. Use scheme http: to use it, e.g.
916 yaz-client no longer does (un)intelligent character set conversions
917 by default. Can be enabled with charset and marc_charset commands.
919 xmalloc trace fix for 64-bit systems such as DEC alpha.
921 Solaris 2.6 compile fix.
923 New function, cql_strerror() translates SRW error codes, as returned
924 by cql_transform_error(), into human-readable English strings. Used
925 in yaz-client diagnostics when appropriate.
927 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
928 converts it into a type-1 query which is sent to the server. This
929 makes CQL available for use with all Z-servers, as opposed to the tiny
930 minority that can handle CQL queries themselves.
934 New Debian package layout similar to the Redhat Package layout.
936 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
937 and search result respectively.
941 Redhat package is now several packages: libyaz (runtime libraries),
942 libyaz-devel (development and documentation, and yaz (utility programs).
943 Package spec file by Morten Bøgeskov.
945 New member 'schema' in struct bend_fetch_rr which the name of requested
946 schema (SRW/SRU) for record (or NULL if none was given). The fetch
947 handler MAY set this to reflect the schema of the returned record.
949 New member 'display_term' in struct scan_entry. GFS now sets member entries
950 and allocates scan entries to be filled by user scan handler. In previous
951 version, entries member was allocated by the scan handler. That still works,
952 but the GFS will ignore member display_term - assuming it was NOT set by
953 the handler. The fact that the GFS now allocates the entries both allows
954 for new members and makes a scan handler easier to write.
956 Fix CQL lex buffer overflow.
958 SRW/SRU recordPacking. For SRW default recordPacking is string. For
959 SRU default recordPacking is string.
961 SRU protocol support for frontend server.
963 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
965 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
967 Added scan for the ZOOM shell (zoomsh).
971 * String Identifers for Schemas (Amendment 5).
972 http://lcweb.loc.gov/z3950/agency/amend/am5.html
973 Old definition for schema
974 Odr_oid *schema; /* OPT */
979 Z_InternationalString *uri;
980 #define Z_Schema_oid 1
981 #define Z_Schema_uri 2
984 * resultCount parameter to Sort Response (Amendment 1).
985 http://lcweb.loc.gov/z3950/agency/amend/am1.html
987 Support for SRW 1.0 over HTTP. This is an optional feature and
988 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
991 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
992 on the same port. SRW SearchRetrieveRequests are mapped
993 to bend_init,bend_search,bend_fetch,bend_close.
995 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
997 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
998 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1000 ZOOM connections are SRW based if schem http is used for hostname
1001 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1002 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1004 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1005 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1006 distance=n, order=true/false, relation=le, prox unit=word. If
1007 n is omitted, distance 1 is used.
1009 Fixed problem with C compiler include path in wrong order.
1011 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1012 on Solaris. Patch from Ko van der Sloot.
1014 New MARC decode API. All new functions operate on a yaz_marc_t
1015 handle. The most important new functions are: yaz_marc_create,
1016 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1017 decode and destroy respectively. Decoder can produce formats
1018 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1019 include/yaz/marcdisp.h.
1021 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1022 to UTF-8, UCS-32, wchar_t or Latin-1.
1024 * Prototypes for yaz_iconv_-functions moved to separate header
1025 include/yaz/yaz-iconv.h.
1027 Make a few private functions 'static' in unix.c. This prevents
1028 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1030 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1031 are set when Init Response is received.
1033 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1034 but returns diagnostic set as well.
1036 New function yaz_strerror which is a portable wrapper for
1037 strerror/strerror_r/GetLastMessage.
1039 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1040 is returned for MARC. If type is "oai", then OAI MARC is returned.
1042 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1045 --- 1.9.2 2002/11/26
1047 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1049 Fix bad race conditions on SIGTERM and terminate gracefully in
1052 Move retrieval (data1) module to Zebra since nobody seems to be
1055 Add GRS-1 render for ZOOM using same format as yaz-client.
1057 --- 1.9.1 2002/10/05
1059 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1061 Fix broken ESpec handling in data1 module.
1063 SGML reader parses comments and makes them part of the data1 tree.
1065 Added several type casts so that YAZ compiles as C++ code.
1067 ZOOM didn't handle PDU encoding failures properly.
1069 Added more Bib-1 diagnostics (approved extensions).
1071 GNU configure: better check for iconv.
1073 More portable use of accept, getpeername. Check for socklen_t. Use
1074 int/size_t if socklen_t is not defined.
1078 PQF parser rejects bad queries - including those with extra
1079 characters in them. PQF parser used to silently ignore that.
1080 Cleaner API for PQF added, which allows you to get detailed
1081 error information for bad queries (see yaz/pquery.h).
1083 Fixed bug in ZOOM_record_get for type "database".
1085 Implemented mini iconv library supporting conversions between
1086 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1088 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1090 --- 1.8.9 2002/08/20
1092 Fixed ZOOM C record cache so that preferredRecordSyntax and
1093 elementSetName is used to check for already fetched records.
1095 --- 1.8.8 2002/08/02
1097 Added three members in bend_initrequest structure to facilitate
1098 character set negotiation.
1100 Fixed a bug in frontend server that could cause indefinite
1101 loops under rare conditions.
1103 Revised character set utilities (charneg.h) so that encoding
1104 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1106 For PQF, directive @term <type> sets term type for Scan/Search.
1107 Here <type> is general, string, numeric, null. The term type
1108 is inherited - just like @attr.
1110 New call odr_set_charset that sets character set conversion for
1111 international-strings on a ODR stream. Prototype is:
1112 int odr_set_charset(ODR o, const char *to, const char *from);
1113 The InternationalString is still represented as C string in YAZ
1114 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1115 won't). On the protocol level, you can use any encoding.
1117 Support for UNIX sockets in ZOOM.
1119 Solaris recv sometimes returns errno == ENOENT. It is treated as
1120 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1122 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1123 both client and server. Code by Morten Bøgeskov.
1125 --- 1.8.7 2002/05/22
1127 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1128 that they can be used directly from Visual Basic. You must recompile
1129 your windows APP if you're using ZOOM.
1131 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1132 Commands "lang" and "charset" sets language and character set respectively.
1133 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1134 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1136 Attributes from multiple CCL fields may be OR'ed rather than merged
1137 using directive "@field or". Fields are still merged by default -
1138 equivalent to "@field merge".
1140 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1143 Fixed bug in zget for parameter ExtendedServicesResponse.
1147 --- 1.8.6 2002/03/25
1149 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1151 Client displays USR.1:SearchResult-1 (hits per term).
1153 Additional Search Info for search in Generic Frontend Server.
1155 Fixed CCL parsing of "field=s".
1157 WIN32 installer - using the excellent NSIS software from nullsoft.
1159 Fixed CCL parsing of "field = - <number>".
1161 Added function yaz_marc_decode that decodes MARC for line mode
1162 display or XML (similar to that used by JZKit).
1164 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1165 Z39.50. But ISO/ILL was, however.
1167 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1168 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1170 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1171 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1173 --- 1.8.5 2002/02/03
1175 New YAZ client features: Command completion and new commands:
1176 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1177 Code provided by Jacob Poulsen.
1179 New call oid_trav, that visits all registered OIDs via callback.
1181 Function ZOOM_record_get now returns const char pointer rather than
1182 void pointer. It saves a lot of type casts.
1184 For YAZ client, command "auth" now allows you to set authentication
1185 in IdPass style. It is enabled when three tokens are given - order
1186 is user, group and password.
1188 Fix memory leaks in MARC record handling for ZOOM.
1190 New option for YAZ client, -k <kilobytes> that sets
1191 maximum record size. Similar to -k option for generic frontend
1192 server and yaz-ztest.
1194 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1196 Prefix query parser reports "fail" when bad attribute set is given.
1198 Fix in MARC decoder. Proximity logging. Fix for attribute set
1199 in scan handler for server. Patches by Shigeru Ishida.
1201 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1204 Configure option --with-openssl=<dir> now works when a directory is
1205 specified. Patch provided by Morten Bøgeskov.
1207 New option for YAZ client, -u <auth>, that sets authentication.
1209 ZOOM fix: error information was sometimes "missing", since error
1210 was cleared/reset too when it shouldn't.
1212 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1214 --- 1.8.4 2002/01/04
1216 Scan for ZOOM API. New object ZOOM_scanset. New functions
1217 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1218 ZOOM_scanset_destroy.
1220 New ZOOM function, ZOOM_connection_last_event, that returns type
1221 of last event (such as "receive data", "send data", "apdu received",
1224 New ZOOM option, schema, that specifies schema for retrieval.
1226 New CCL feature. Qualifiers can be aliases for one or more
1227 other qualifiers (if more than one is given, OR is used).
1229 ZOOM uses named result sets if target supports it.
1231 Two new YAZ client commands: . (dot, which sources a script of YAZ
1232 client commands), and ! (to execute shell command.). Implemented
1235 Working on Debian packages.
1237 --- 1.8.3 2001/11/19
1239 YAZ client enables named result sets only if target supports it.
1241 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1243 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1244 with key="host" to get same result.
1246 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1247 Function Z3950_resultset_record(s) returns references to records
1248 "owned" by resultset. To become owner use Z3950_record_clone.
1250 Function z_ext_record handles Extended Services. Thanks to
1253 --- 1.8.2 2001/11/12
1255 CCL Parser fix: ignore token comma when dealing with and-lists.
1257 Documentation updates for COMSTACK.
1259 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1260 Changed prototype Z3950_records. For some functions, int parameters
1261 were changed to size_t.
1263 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1266 New MARC decode/display function, marc_display_exl, which properly rejects
1267 non-ISO2709 records. YAZ client uses it.
1269 --- 1.8.1 2001/10/29
1271 Fix bug: local attribute set wasn't set correctly in PQF strings.
1275 * Old Z39.50 codecs no longer supported.
1277 Added ZOOM C binding. See http://zoom.z3950.org/
1279 Renamed states for COMSTACKs to avoid confusion with events.
1281 Implemented cs_look and proper cs_rcvconnect.
1283 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1285 Configure detects POSIX threads on OpenBSD.
1287 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1288 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1290 When error is returned from present handler, non-surrogate diagnostic
1291 is returned in present response (and fetch handler is no longer called).
1293 * Minor adjustments to pquery parser (PQF). Token characters may be
1294 escaped by using backslash (C-style).
1296 PQF parser allows string attribute values to be specified. For @attr,
1297 non-numeric characters after the equal-sign are treated as strings
1298 (e.g. @attr 9=title).
1300 CCL trunction character may be defined (@truncation in file)
1302 * function zget_ExtendedServicesRequest sets waitAction to
1303 waitIfPossible (was wait).
1305 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1308 CCL operator names may be set in field definition files (CCL_bibset).
1309 See ccl/bib1 for an example.
1311 Fixes in ASN.1 compiler for C++ compatibility.
1313 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1314 and "op_or" to avoid conflict with C++.
1316 Fixed problem with GNU readline detection on Redhat 7.0.
1318 Added step-size for Scan backend handler.
1320 Fixed bug that made the frontend server crash when no attribute
1321 set was specified for scan.
1323 Front-end server automatically switches to original working directory
1324 when installed as an NT service. Previously -w had to be specified to
1327 Added extended attributes for retrieval module (data1), so that data1
1328 records carry d1_readXML/SGML attributes. d1_read also supports
1329 null-data rules ( <tag/>)
1331 On UNIX when POSIX threads are available, a separate library libyazthread
1332 is created. Programmers should link with that library and the yaz library
1333 when using threads. The reason for the split was that some applications
1334 on Linux, such as Apache, doesn't work well when using shared objects that
1337 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1338 (or any frontend server) in SSL mode by specifying ssl: followed by
1339 address. Only tested on UNIX.
1341 Added feature for CCL module. Virtual structure s=al or s=ol generates
1342 and-list and or-list respectively instead of phrase search.
1346 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1347 log_mask_str. This was done to avoid name conflicts with other libraries
1348 (such as other PHP extensions).
1350 Added raw OID member for preferred record syntax (request_format_raw)
1351 and returned record syntax (output_format_raw) for backend fetch method.
1353 Config file yaz-config now accepts options so that it returns specific
1354 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1356 Shared library support for UNIX using GNU libtool.
1358 * Modified backend interface. Request/Response struct's replaced by
1359 one read/write C struct. For example bend_fetchrequest and
1360 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1361 Every handler - even search has to be registered in bend_init
1362 handler. This means that the YAZ library no longer refers to
1363 external functions and it makes it possible to make the whole
1364 thing a single DLL/SO.
1366 Added Segment handler for backend server.
1368 Added Zmbol/Zebra administrative functions to YAZ client.
1370 Threaded frontend server on UNIX (when POSIX Threads are available).
1371 Starting the server with option -T enables multi-threading.
1375 Added configure option --enable-comp/disable-comp to control use
1376 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1377 located in sub directory asn.
1379 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1380 in ${exec_prefix}/bin along with the other programs yaz-client and
1383 GNU automake used to maintain makefiles.
1385 Added several OID's.
1387 Changed retrieval module so that we can load records with no abstract
1388 syntax defined. Tagpaths in these records are fully composed of string
1391 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1395 On UNIX, the generated makefile now supports a proper 'make install'.
1396 The prefix can be set via GNU configure to set the install location
1397 (default is /usr/local).
1399 * YAZ programs client and ztest were renamed to yaz-client and
1400 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1401 locations, such as /usr/bin,/usr/local/bin,etc.
1403 * YAZ Header files were moved from include to include/yaz. YAZ Header
1404 files are referred to as include <yaz/log.h> rather than <log.h>.
1405 The YAZ include path (-I ..) is therefore the same as before. Programmers
1406 should update their #include statements or use -Ipath/include/yaz
1407 instead. The main motivation for doing this change is that YAZ header files
1408 can be installed in "standard" locations /usr/include,/usr/local/include
1409 without introducing conflicts, since ALL YAZ header files are stored
1410 in subdirectory yaz (under /usr/include for example).
1412 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1413 rather than project/workspace files. We switched because project files
1414 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1417 Changed name of logging function, logf, to yaz_log, to prevent name
1418 clash with some math-log functions. The YAZ header log.h defines logf
1419 to yaz_log (#define) so there should be no incompatibilities by this
1422 Added bend_start/bend_stop handlers for server. These handler are
1423 called on start/stop of server. For windows they are called whenever
1424 a service is started/stopped.
1426 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1427 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1428 in util/yc.tcl. The auto-generated C code structures are, in a few
1429 cases, incompatible with the old decoders. There are differences in the
1430 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1431 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1432 The preprocessor variable ASN_COMPILED is defined when the compiled
1433 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1434 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1435 wish to use the old encoders/decoders you can specify --disable-yc
1438 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1439 version so that it supports both new - and old version of DB Update
1441 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1442 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1443 change. The name parameter can be set to 0 in which no name is specified
1444 for the construction. The macros odr_implicit and odr_explicit sets name
1445 parameter to zero for the construction involved. New macros
1446 odr_implicit_tag and odr_explicit_tag are similar to the others,
1447 except that a name parameter is added. For programmers' that don't use
1448 ODR they probably only need to change the call to z_APDU and z_External.
1450 Added access control facility by interfacing the TCP wrapper library.
1451 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1452 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1453 name of the daemon and enables the access control as specified in
1454 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1456 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1457 den Dool <H.M.vdnDool@kub.nl>.
1459 Added reference ID parameter to most functions in server API - refer
1460 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1462 Changed name of ccl library to libccl.a (was ccl.a).
1464 Fixed bug in decoder for Explain (Category TargetInfo).
1466 Added support for GNU readline in client. Thanks to Jacob Poulsen
1467 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1469 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1470 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1471 IMPLEMENTATION! This change was made to the development version before
1472 the ZIG decided to retract the amendment. If any users MUST be
1473 compatible with the original Update definition, PLEASE CONTACT US, and
1474 we will include a separate definition corresponding to the old Update
1475 ES. Note that because of the change to the ASN.1 of the
1476 TaskPackageRecordStructure we cannot define a single structure that
1477 will support both versions.
1479 * Added const modifier to buffer parameter for some ODR/BER encoding
1480 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1481 completeWAIS, odr_dumpBER.
1483 Fixed bug in client.c which caused a crash when a scanResponse didn't
1484 contain positionOfTerm.
1486 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1487 * will cause an error in a client if a non-YAZ target sends both a
1488 * list of Scan entries and non-surrogate diagnostics.
1490 Retrieval module enhancements. Tag sets may be typed in the reference
1491 to it. From the .abs-file the "tagset" directive takes a third optional
1492 integer type for the tag set referenced. From a .tag-file the "include"
1493 directive takes a third optional type as well. The old "type" directive
1494 in the tag set itself is still recognized but acts as the default type
1497 Backend interface change. Individual Scan terms returned from bend_scan
1498 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1499 in include/backend.h.
1501 Retrieval module enhancements. Multiple tag sets and attribute sets may
1502 be specified in abstract syntax specs. Revised the error/warning for
1503 logging messages reported by the retrieval module when reading the
1506 Object Identifier system (oid_..) changed. The API is backwards
1507 compatible but the oid-routines now allocates new OID's when needed.
1508 Raw OID's may be specified in oid_getvalbyname.
1510 YAZ now uses GNU configure to generate Makefile(s).
1512 * Minor changes in some of the member names of DeleteResultSetRequest and
1513 DeleteResultSetResponse. See include/proto.h.
1515 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1516 and added member 'languages' in TargetInfo (which was missing).
1518 Changed the way attribute sets are handled in the retrieval
1519 module. These are now cached, just like the abstract syntaxes
1522 Changed YAZ so that it links with compiled ASN.1.
1524 Added Explain-schema definitions and mapping routines. The following
1525 Explain categories have been implemented: AttributeDetails,
1526 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1528 Fixed minor bug in Windows version of Server Library.
1530 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1532 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1534 Added EXTERNAL: UNIverse Resource Report (non-standard).
1536 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1537 ENUMERATED and SET OF.
1539 * Added 'const' to some of the char pointer arguments for the
1540 functions, data1_read_node, data1_getelementbytagname,
1541 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1544 Fixed bug in data1_insert_taggeddata - the last_child member of
1545 parent wasn't initialised.
1547 * Changed data1_read_record and data1_read_node so that the supplied
1548 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1549 doesn't refer to any parts of the "SGML"-buffer.
1551 Fixed bug in server library (Windows version of statserv_remove).
1553 * Changed code so that it compiles as C++. The type definition
1554 of Odr_fun which is a member of Odr_arm was changed. The result is,
1555 that an explicit typecast is needed for the fun pointer when
1556 using Odr_arm - as in:
1557 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1559 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1561 Implemented the new structured date and time definition as approved
1562 by the ZIG. Added schemaId element to the specificTag in Espec-1
1563 (also approved at the last ZIG). Thanks to RVDM.
1565 Added some Object identifiers (RVDM).
1567 Changed the Update Extended Service (RVDM).
1569 Added command "refid" to client which specifies referenceId for
1570 the following requests.
1572 Implemented extended service handling for server. See ztest.c
1573 for an example as well as backend.h. New handlers are registerd
1574 in the Init handler.
1576 * Changed interface for sort in server.
1578 Added new members to statserv_options_block. It allows a server
1579 to read options from another source than just the command line. Thanks
1580 to Charles Woodfield.
1582 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1583 renamed to zboolean. Some C++ compilers complained about the name.
1585 Minor changes to gils.abs. Added index 's' (sort) on title
1586 and date/time-last-modified.
1588 --- 1.4pl2 1998/1/30
1590 Fixed bug in server library regarding inetd mode (-i). This bug
1591 was introduced by release 1.4.
1593 --- 1.4pl1 1998/1/29
1595 Added sort facility in client and backend server interface.
1597 Fixed problem with dependencies in Makefile(s).
1599 Fixed bugs for encoders/decoders of extended services and
1602 Implemented sub-tree feature for schemas. Sub-trees are
1603 referenced in *.abs-files. See explain.abs for an example
1604 of the use of this feature.
1606 Modified bib1.att; local attributes for ANY didn't include
1607 ANY itself (only affects use of the retrieval module).
1609 Fixed bug in plain SGML reader in function data1_read_node:
1610 tags with prefix "var" was incorrectly interpreted as variants.
1612 Added feature "sub-schemas" to enable references to - and definitions
1613 of - group of elements.
1615 * Removed member parent from type data1_element (in data1.h).
1617 Implemented function odr_nullval() that returns the value of
1620 * Removed member num_children from data1_node (in data1.h).
1622 Made NT service interface part of the server library. The
1623 function statserv_main uses the NT service when required and
1624 calls the statserv_start / statserv_close routines.
1626 Routine zget_SearchRequest and zget_PresentRequest fills
1627 resultSetName/Id member with "default" instead of "Default".
1629 Fixed memory leak in server. Request queue member wasn't freed.
1631 Fixed nmem_exit so that memory is freed.
1635 Revised the CCL parser utility to be thread safe.
1637 Added function, oid_ent_to_oid, to replace the function
1638 oid_getoidbyent, which is not thread safe.
1640 * Added nmem_init and nmem_exit to initialize and release
1641 NMEM resources. Function nmem_init should be called once in the
1642 initial thread before NMEM/ODR is used. statserv.c and client.c
1643 have been changed accordingly. The change was necessary to make
1644 NMEM thread safe. The NMEM memory pool is shared amongst threads
1645 in a process. Unix-based applications will still work fine without
1648 Added NT Services interface for the the Z39.50 (statserv) Server.
1649 Refer to the ztest.c source on the usage.
1651 Windows 95/NT port using MSVC5.0. Project files are included in the
1654 * Defined new 'global' handle for the retrieval (data1) system. The
1655 new handled, data1_handle, describes the state of the data1 system.
1656 This handle is passed as first argument to virtually all
1657 data1 related routines. The functions data1_create and data1_destroy
1658 creates and destroys a data1 handle respectively.
1660 Added ODR encode stream member to all backend request structures
1661 init, search, scan etc. This stream should be used to allocate all
1662 memory used for the response when thread safe operation is needed.
1664 Changed the comstack utility, cs_addstr, to be thread safe. The
1665 returned hostname string returned by the function is now part the
1668 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1669 function. The cs_straddr takes a COMSTACK handle as argument, so this
1670 function must be used after cs_create and before bind/connect.
1671 This function is thread safe.
1673 Moved test server to 'ztest' directory - generic server code still
1674 in 'server' directory.
1676 Made prefix query (pquery.c) utility thread safe.
1678 Added new function modifier YAZ_EXPORT to 'export' public DLL
1679 functions when using windows (see include/yconfig.h).
1681 Added definitions to the OID database (util/oid.c) (RVDM).
1683 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1685 Added call to ccl_rpn_delete in client program.
1687 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1688 release of RPN structure.
1690 Added support for C++, headers uses extern "C" for public definitions.
1691 With input from RVDM.
1693 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1694 Thanks to Ronald van der Meer (RVDM).
1696 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1698 Added support for private extensions to the OID database
1699 (oid_setprivateoids()). Thanks to RVDM.
1701 Added optional, physical ANY (key replication)
1703 Fixed null-reference problem in GRS-1 output filter.
1705 Proximity operator added to Prefix Query Format (PQF).
1707 In test client command "base" accepts multiple databases.
1709 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1713 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1715 Smallish bug-fixes in the new encoders/decoders (explain).
1717 Bug fixed in DeleteRequest.
1719 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1721 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1723 Added SOIF syntax (using private OID for now) to retrieval module and client.
1725 Added Update extended service.
1727 Added SearchResult-1 additional info structure.
1729 Added optional CCL (ISO8777) interpreter as separate module. Available
1732 --- 1.2 1996/6/10 (1st anniversary release)
1734 Added Summary record syntax. Lightly tested.
1736 Added OPAC record syntax. Untested.
1738 Added ResourceReport service encoders/decoders. Untested.
1740 Fixed bug in z_Unit - wrong tagging on unitSystem.
1742 Fixed bug in the DiagRecs decoder.
1744 Added options for max PDU size and session timeout to frontend-server.
1746 Added documentation of query-language parsers and other supporting utilities.
1748 [frontend-server] Added Attribute set to the bend_scanrequest API.
1750 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1751 surrogate diagnostics were generated.
1753 [retrieval] Allow multiple local values for attribute.
1755 [retrieval] Allow multiple attributes per element in .abs files. index type.
1757 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1759 --- 1.1pl2 1996/4/10
1761 Minor changes, mostly specific to Zebra's requirements (retrieval)
1765 Repaired bug in frontend server when running multiple listening
1766 endpoints in dynamic mode.
1768 z_External() now won't break if a known, ASN.1 value comes encapsulated
1769 in an octet-string. The value will pass through unmodified in an Odr_oct.
1771 Added a bit of code to the demo client to decode & display
1772 ASN.1-structured records represented in the octet-aligned branch of
1773 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1775 Added z_ext_getentbyref() to the ASN module. Doc updated.
1777 * Completed the SCAN definition in the ASN module. This may break SCAN
1778 code based on older YAZ-versions at compile-time. The fix is easy -
1781 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1782 under the SCAN definition. Remember to initialize this, server-people.
1784 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1785 that this does not extend to ODR and ASN.
1787 Comstack allows insertion of established socket (primarily for
1788 inetd-operation of servers). Doc updated.
1790 Front-end server can now start from the inetd in TCP mode. Doc
1793 --- 1.0pl4 1996/1/24
1797 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1798 the rank and record number.
1800 Adjustments to the frontend server.
1802 Fixed diagnostic BER dumper. It ignored the file argument.
1806 Various changes to retrieval module.
1808 Changed the union discriminators of the protocol files from enums to
1809 ints paired with #defines.
1811 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1814 *Changed operator in the RPN structure to 'roperator', again to avoid a
1817 Fixed problems in Explain decoders/encoders.
1819 --- 1.0pl2 1995/12/6
1821 Memory bug in log module fixed.
1823 --- 1.0pl1 1995/12/5
1825 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1827 Bug in Explain DatabaseInfo module fixed.
1829 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1833 The shift to v1.0 signals that we now consider the *core* functionality
1834 of YAZ reasonably stable (the core being more or less equivalent to
1835 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1836 tested (Explain not at all - though that will happen soonish).
1838 Minor changes to code to support Windows port.
1840 Various minor changes after we're getting to use GRS-1 & co. more.
1842 Added Espec-1 format.
1844 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1845 of the protocol and it cannot be selected when encoding (maps into 'string'
1846 when decoding). Needed to talk to some servers.
1848 Demo client can request simple element set names.
1850 Added Diagnostic Format encoders/decoders.
1852 Added simple Close handling to frontend server (no hooks for resource
1853 reporting yet), and demonstration client.
1855 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1857 --- 1.0b3 1995/08/24
1859 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1860 handled incorrectly when records were requested in the searchResponse. This
1861 will only affect you if you use the frontend-server.
1863 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1864 Test-client will ask for and print GRS1. Ztest will return dummy records
1867 Added Explain encoders/decoders to the service-level API. Untested.
1869 Added Extended Services: Item Order encoders and decoders to the Service-
1870 level API. Untested. We could use a recent copy of the pertinent bits
1871 of the ILL protocol to add those bits.
1873 Added diagnostic format 1 encoders/decoders to the service-level API.
1876 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1877 odr_cons.c, which causes a more correct output.
1879 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1880 was always set to 0 when no records were requested in the searchRequest.
1882 * Added better external-handling. This shouldn't harm old code that
1883 *encodes* externals. It can break code that looks for a
1884 'single-ASN1-type' representation, since those types that are known
1885 are now decoded immediately. Look at the SUTRS sample code in
1886 seshigh.c and client.c. Documentation updated.
1888 Handling of structured records in bend_fetchresponse. Length -1 marks
1889 structured record, type is deduced from format field.
1891 --- 1.0b2 1995/06/27
1892 Fairly quick maintenance release to add SUTRS support.
1894 Fixed handling of SUTRS records in the demonstration client.
1896 * Added format field to the bend_fetchrequest and bend_fetchresponce
1897 structures of the backend API (frontend server). When the record is
1898 returned, the value of the format field is mapped to an OID. The
1899 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1900 of the record. The special value VAL_NONE in the bend_request means
1901 that no specific format was requested by the client. Documentation
1902 updated accordingly. Test server (ztest) will return a fixed dummy
1903 SUTRS record if your client requests SUTRS.
1905 Documentation updated accordingly.
1907 You can now set external libraries and RANLIB support in the top-level
1911 First public release.
