1 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2 of YAZ and has been so since YAZ 2.1.10.
4 Implemented ZOOM_record_error which returns error information for
5 record (surrogate diagnostic).
9 Updates for SRU Update by Ko van der Sloot:
10 1. Changed name from "operation" to "action"
11 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
12 versions in the code, marked as 'backward compatible'.
13 3. Added diagnostics for SRU Update.
15 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
17 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
19 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
21 For GFS, fixed problem with SRU diagnostic 'First record position out of
22 range' being issued for 0 hits.
24 zoomtst10 part of Windows Build.
28 Implemented yaz_filepath_comp which splits a path into file path
29 components (required by Zebra 2.0.3+).
31 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
32 BSD inspired license until now so this should not have any real impact on
33 anybody. See http://www.opensource.org/licenses/bsd-license.php
35 Fixed bug #687: Missing log lines.
37 Fixed bug #678: CQL to PQF translation does not preserve double-quote
40 Fixed bug #689: SRU diagnostics to be added.
42 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
43 whether a connection is idle (no more work do do).
47 Change type of optval from long to int for invocation of setsockopt with
48 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
50 Added support for specifying the max log file size for the Generic
51 Frontend Server. The size is given with option -r.
55 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
59 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
62 Fixed bug in Generic Frontend Server that could cause a server to stop
63 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
65 For the generic frontend server, the maximum record size is used as maximum
66 size of incoming packages (SRU + Z39.50). The value until was previously
67 only used in Z39.50 Init negotiation and, later, in a session controlled
68 sizes of records returned. This is controlled using -k option. It can be
69 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
73 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
76 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
78 New option for yaz-marcdump -lpos=value which allows setting a portion
79 of MARC header to a certain value.
81 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
83 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
84 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
88 Fixed problem with SRU mode type (soap, get, post) for yaz-client
91 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
95 Fixed MARC ISO2709 encoding routines to deal with character set
98 Minor changes to GFS logging. Database included in search request log
101 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
102 cached/multiple records.
104 Shared libraries are built by default on Unix+configure.
106 Changed cql2pqf transformation to use a different evaluation order. The
107 new order is: always, relation, structure, position, truncation, index
108 and relationModifier. Old order was: always, relation, relationModifier,
109 structure, index, position, truncation. Note that the the latter ones
110 override former ones for identical attributes.. The new scheme means that
111 it is possible to override any existing attribute with a relationModifier.
112 And also that it is possible to override everything for the index rule
113 (except the ones listed in relationModifier). No order is perfect but this
114 one, we believe, covers more real cases.. The "always" should have been
115 called "default", since the attributes there can be overridden with all
118 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
119 compilation phase, but also for yaz-config --cflags output. This allows
120 us to have public headers with Libxml2 stuff in them . It should also,
121 eventually, make Libxml2 checks redundant in packages using YAZ, such
124 --- 2.1.22 2006/06/15
126 Changed SRU update structure bend_update_rr so that SRU diagnostics are
127 stored in uri, message and details.. Previously diagnostics were stored
128 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
129 compatibility.. but he's probably the only one affected, so.
131 Added support for CCL, compiled on the client side, in ZOOM-C. This
132 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
133 input; the resulting query objects can be used for for searching with
134 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
136 YAZ' configure searches for OpenSSL by default.
138 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
139 SL_CTX_use_certificate_file. See
140 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
141 for more info. Thanks to Ko van der Sloot.
143 --- 2.1.20 2006/06/02
145 Bug #600: SRU GET, POST support for yaz-client. Introduced
146 command 'sru' which selects method SOAP/GET/POST.
148 Allow missingValueAction to be specified for the sortspec string -
149 function yaz_sort_spec. By default, the missing value action is null.
150 Use ! to specify "abort". Use = followed by stringvalue to specify default
153 Ensured that Present-handler (if defined) is called in GFS before any call to
154 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
155 searchRetrieve requests.
157 Documentation for YAZ is now based on the Docbook XML/XSLT using
158 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
159 is no longer depending on jade/openjade or docbook-to-man scripts.
160 PDF is no longer part of the distribution - but can optionally be
161 made using DSSSL/jadetex or FOP.
163 Added retrieval handling support in Generic Frontend Server to support
164 conversion between MARC/XML as well as XSLTtransforms. See
165 etc/yazgfs.xml for an example.
167 Added Authentication support to Generic Frontend Server in SRU
168 mode. Authentication using HTTP Basic is supported, as is the use
169 of 'x-username' and 'x-password' parameters in the request itself.
171 Added support for a new character set MARC8s identical to MARC8 except
172 that it converts combined characters to single Unicode characters in the
173 Latin-1 range (when possible).
175 --- 2.1.18 2006/04/24
177 ASN.1 compiler 0.4: generates brief Doxygen file header for
178 generated .h/.c files.
180 Utility yaz_iconv now supports conversion to MARC-8.
182 New facilities for the MARC module. The reading - and writing of
183 content are separate methods for the yaz_marc_t handle. The following
184 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
185 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
186 format). Write functions have prefix yaz_marc_write_.. The existing
187 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
188 available. Removed support for OAI-MARC and simplexml (not the
189 simplexml from PHP5).
191 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
192 to be returned for this connection.
194 --- 2.1.16 2006/03/31
196 Allow multiple languages and charsets to be specified with
197 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
198 negcharset iso-8859-1,utf-8
200 Translation of proximity nodes from CQL into PQF now works.
202 Moved to automake 1.8, 1.9.
204 Added function yaz_log_set_handler which allows a log handler to be
205 installed. This handler will be called for all log messages. Output
206 to file is also produced; but that can be disabled by passing NULL
207 fname to yaz_log_init_file.
209 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
211 For SRW (including GFS), accept application/soap+xml as content-type
214 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
215 produces NO stylesheet reference even if a default stylesheet is specified
218 --- 2.1.14 2006/03/14
220 Updated Windows package to include yazd.dll + yazd.lib for the
221 Development component.
223 If the environment variable YAZ_LOG is set, then it is used as a
224 string indicating the default level of logging to use if not
225 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
226 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
227 used as before. So, for example, to omit warnings from YAZ logging,
230 cql_transform() now map structure and other attributes before indexes,
231 so that index-specific structures and other attributes can override
232 defaults. So now a combination of mapping specifications such as:
234 index.dc.date = 1=date-modified 4=5
235 does the right thing.
237 cql_transform() now also respects the "always" mapping specification,
238 which establishes an initial set of attributes to be used for all
239 terms except where overridden by more specific attributes associated
240 with the index, relation or modifier.
242 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
243 which mode to use; one of "post", "get" or "soap" (SRW, default).
245 Fixes for yaz_iconv routines: changed trie-based character set conversions
246 to use only non-negative values for bit fields due to Sun's C compiler not
247 supporting negative values.
249 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
250 sequences where not read correctly. Fix by Rustam Usmanov.
252 Updated win/makefile to use options, settings which makes things
253 compile with VS C 2005.
255 --- 2.1.12 2006/02/01
257 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
259 In ZOOM socket code, use select instead of poll on MacOSX.
261 ZOOM-C now support client-side compilation of CQL into RPN that is
262 sent to the server, enabling CQL to be used against all Z39.50
263 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
264 ZOOM_query object, and submit it using ZOOM_connection_search().
265 The CQL-to-RPN translation uses a configuration file, the name of
266 which must be specified in the Connection's "cqlfile" option.
268 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
269 function, which takes as its start-term parameter a ZOOM_query object
270 (which may have had either CQL or RPN set into it).
273 --- 2.1.10 2005/11/29
275 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
276 GFS to support this as well. Backend handler, bend_srw_update, does the
277 update work. Code contributed by Ko van der Sloot.
279 Allow retrieval of Search Result-1 information in ZOOM by the use of
280 options that are attached to a result set. ZOOM documentation updated
283 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
284 UTF-8 conversion. Patch by Raj Patel.
286 Added option -m to GFS to control formatting of timestamps in log file.
288 Added 'exit' as synonym for 'quit' in yaz-client
290 Added support for specifying SRW resultSetId + resultSetIdleTime in a
291 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
292 for the new members. Patch by Ko van der Sloot.
294 Added support for SRU POST. It is supported for content-type
295 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
297 Do not build the separate Multi-threaded (MT) library libyazthread.la.
298 Instead make the library libyaz.la multi-threaded. Threading as a whole
299 can still be disabled by configure option --disable-threads. Previosly,
300 with older GLIBCs there were problems with MT libs under Apache. This
301 has now been fixed a long time ago.
303 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
306 CQL module modified to be case insensitive for relations/indexes/operations.
308 Fixed bug in CQL transform code: incorrect value relationModifieder
311 Added 'show all' command for yaz-client which retrieves all results
314 Added new yaz-client, xmles, which takes a (private) OID and
315 a document to be sent as an extended service request.
317 Describe new yaz-client commands wait_response and set_auto_wait.
319 Increase TCP/IP listener backlog from 3 (which I am guessing was
320 copied from the SunOS manual entry way back when) so SOMAXCONN, so
321 that the socket will queue as many incoming connections as it's able
322 to handle ongoing connections. In other words, it will never now
323 refuse a connection that it would be able to handle merely because
324 it's not got around to accepting() enough of the pending connections
325 yet. This is the behaviour anyway under Linux, where the listen()
326 argument is ignored; but not under BSD and on systems such as
327 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
328 YAZ-based servers should now be uniform across operating systems in
331 yaz-marcdump uses 64-bit file access on some systems. This is enabled
332 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
333 This allows yaz-marcdump to read large MARC batches (>2 GB).
335 Modified all YAZ source files - except the source which is auto-generated
336 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
339 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
340 corresponding to the existing *_setl() function. These allow option
341 values containing arbitrary valuues.
343 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
344 ZOOM_resultset_sort() in new applications. Its behaviour is identical
345 except that it returns an indicator of whether or not the sort
346 criterion was accepted (0 for OK, -1 for invalid).
350 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
351 MARC output rather than returning "new" buffer.
353 yaz-client warns about unknown init options.
355 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
359 Added support for SRW sort in Generic Frontend Server. Patch
360 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
361 sortKeys - or NULL if none is provided.
363 Fixed bug #307: It was impossible to specify indefinite/no timeout
364 for ZOOM_event. Special timeout value -1 now means indefinite timeout
367 Added support for multiple languages and charsets to be specified in
368 ZOOM. Each charset/language is separated by a blank. If negotiation is
369 in effect in init-response, Option
370 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
371 Code based on patch by Vasiliy Osadchuk.
373 Fixed bug #306: infinite recursion that occurred when calling
374 yaz_log_level_init as the first call (before other log level or
377 Fixed bug in scan handling in front end server: if preferred-Position-In-
378 Response was non-present, a NULL pointer referece was performed.
382 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
383 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
384 now defined for all those error codes. So instead of putting 109 in
385 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
386 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
388 Modified the yaz-marcdump utility to skip garbage bytes between MARC
391 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
393 Program yaz-client now exits and produces an error message if multiple
394 Z39.50 servers are specified on the command line (none or one allowed
397 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
402 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
404 Fixed bug #272: Preserve spacing for CCL terms.
408 Added support for virtual hosts and multiple backend servers for
409 the YAZ frontend server. The configution is XML based and
410 support specificition of CQL to RPN mappings and explain information.
411 See section "Virtual Hosts" in the YAZ manual.
413 Extended OPAC display utility. OPAC display utility renders
414 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
415 to supplement yaz_marc_decode_wrbuf.
417 Fixed a bug in MARC decoder that could caused it to crash for some
418 invalid MARC records. More diagnostics and warnings where added in
419 XML output (warnings, etc are stored in comments).
421 --- 2.0.34 2005/02/08
423 Fixes for UNIX domain sockets. Bug #261.
425 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
427 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
428 Added yaz_marc_subfield_str which defines subfield lead string which is
429 used in YAZ_MARC_LINE format. Default string is blank+$. Added
430 yaz_marc_endline_str which defines end of fields string used in
431 YAZ_MARC_LINE format. Default string is newline.
433 Experimental support for MarcXChange. This format can be produced
434 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
435 http://www.bs.dk/standards/MarcXchange.xsd
437 Added yaz-client commands scansize that sets maximum number of
438 entries to be returned by scan.
440 --- 2.0.32 2005/01/11
442 Added support for SRW scan in yaz-client and Generic Frontend Server.
444 * Added whereInList member to SRW Scan Term.
446 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
448 Fixed NMEM system to return aligned blocks on the smallest boundaries
449 that are suitably aligned for all possible types on the particular
450 architecture YAZ is being built for.
452 --- 2.0.30 2005/01/04
454 Fixed numerious warnings that was issued with newer versions of GCC.
456 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
457 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
460 Make YAZ Generic Frontend Server slightly faster.
462 Enhance (and reduce) logging for Generic Frontend Server.
464 Revert YAZ log system so that it flushes every write operation
465 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
467 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
468 instead of LOG_, due to name clash with syslog(3). LOG_ are still
469 present. New applications should define YAZ_USE_NEW_LOG=1 - this
470 will effectively disable old definitions.
472 --- 2.0.28 2004/11/09
474 Added yaz_log_time_format which specifies log format using
477 Added yaz_log_module_level which returns mask for a module. Value
478 is non-zero mask a if module is enabled; zero if disabled.
480 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
481 in include/yaz/cql.h.
483 Fixed bug #176: Dont throw diagnostics on empty SRU args.
485 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
487 Fixed bug #172: RPM builds does not enable SSL.
489 Doxyfile.in part of dist. Doxyfile generated by configure.
491 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
492 are given and the corresponding component does not exist.
494 Extend CCL documentation in YAZ reference. Describe r=r.
496 --- 2.0.26 2004/10/01
498 Fixed MARC->MARCXML conversion to properly deal with
499 fields, subfields, indicators having non-ASCII characters.
501 Fixed MARC->MARCXML conversion so that ASCII control characters
502 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
505 Added YAZ GFS support for conversion from Z39.50 surrogate
506 diagnostics to SRW surrogate diagnostics.
508 Bug fix: YAZ GFS did not return schema in explainResponse.
510 --- 2.0.25 2004/09/30
512 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
513 now converts recordSchema to elementSetName as well as schema URI.
515 Fixed bug in COMSTACK that prevented HTTP request packages from being
518 --- 2.0.24 2004/09/29
520 Added CCL facility r=r "range" which is similar to r=o "ordered" but
521 does not require white-space before and after the dash in a range, e.g.
522 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
525 Fixed a few AC_TRY_LINK configure tests that did not operate properly
526 due to new GCC removing "redundant" code.
528 Added yaz-client commands scanpos and scanstep that sets preferred
529 position and step-size for scan.
531 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
533 Added CCL utility ccl_qual_buf which parses one or more CCL
534 spec lines in a buffer.
536 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
537 of name and value - ignoring empty lines and comments.
539 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
541 Added odr_get_element_path which returns current element path for an
542 ODR handle. This utility is useful in error handling or user-defined
545 Added ODR_PRINT utility odr_set_stream which is is a more generic
546 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
547 to a write function and pointer to close function. The close function - if
548 non-NULL - will be called during odr_destroy.
550 Fixed bug in CCL parser where truncation char was not removed from
551 right side when truncation=both was in effect.
553 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
556 --- 2.0.23 2004/08/11
558 Fix buffer overrun in CQL parser when dealing with proximity (%).
560 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
561 to UTF-8/UCS conversion is now only based on codetables.xml.
563 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
565 --- 2.0.22 2004/08/06
567 Add support for more "commit changes" in ZOOM (uses Extended Services).
569 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
572 Yet another small fix for configure of SSL.
574 --- 2.0.21 2004/05/14
576 Fix SSL libs for configure when --with-openssl=DIR is given.
578 --- 2.0.20 2004/05/10
580 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
582 SSL comstack now uses yaz.pem certificate file on server side
583 by default. Certificate filename can be configured by calling
584 comstack function cs_set_ssl_certificate_file before cs_bind is used.
586 Fix bug regarding multiple calls to ZOOM_connection_connect.
588 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
590 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
591 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
593 ZOOM now allows inspection of X509 peer certificate for verification.
594 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
596 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
597 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
598 as "modular" but it simplifies things.
600 Added cs_get_peer_certificate to that returns peer X509 PEM.
602 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
603 NULL if SSL is unavailable.
605 Documentation about MARC decoding tools.
607 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
609 --- 2.0.19 2004/03/30
611 Rename CHANGELOG to NEWS to follow GNU style packing.
613 Fix bug with missing initialization of member in init_diagnostics.
614 This bug affects threaded version of GFS server.
616 --- 2.0.18 2004/03/20
618 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
621 Ensure zlib.dll is packed with Windows install.
623 --- 2.0.17 2004/03/17
625 Fix encoding of xsd:string to use text instead of CDATA.
627 Fix endless loop in CQL parser with unbalanced ".
629 Use a more compact way to store MARC-8 conversion tables.
631 --- 2.0.16 2004/03/16 Debian only
633 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
636 Update CQL parser to use new CQL 1.1 modifiers for booleans and
641 --- 2.0.15 2004/03/01
643 Another fix for decoding of XML packed records.
645 --- 2.0.14 2004/02/25
647 Fixes for Chunked encoding. White space not ignored after length spec.
649 Update NS and use default NS for SRW diagnostic elements.
651 --- 2.0.13 2004/02/23
653 Implement ZOOM_resultset_cache_reset which resets record cache.
655 Implement ZOOM_resultset_sort which sorts a result set.
657 Implement chunked HTTP transfer.
659 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
661 --- 2.0.12 2004/02/16
663 Added member 'schema' to bend_explain_rr structure so that backend
664 can specify explain record identifier. Defaults to Zeerex 2.0.
666 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
668 --- 2.0.11 2004/02/16
670 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
673 Added init command for yaz-client which sends "extra" init request.
675 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
676 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
678 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
680 Make ZOOM error code for "invalid query".
682 Fixed compilation for SSL which wasn't properly enabled for all platforms.
684 --- 2.0.10 2004/02/05
686 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
689 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
691 Added option -p <file> to make Generic Frontend Server to write PID file.
693 Added option -D to put Generic Frontend Server in background on its own.
695 Make ZOOM C recognize option "password". If unset, "pass" is used
696 (for backwards compatibility).
698 Fixed a bug in Generic Frontend Server that could make it crash if a
699 client sets characterSetNegotation bit, but didn't pass negotiation stuff
702 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
703 Must be issued before open, in order to be in effect.
705 --- 2.0.9-6 2004/01/12 Debian/Windows
707 Make the SRU server more picky WRT unknown params, etc.
709 Bug fix: ZOOM scan response didn't return displayTerm - when present.
711 New YAZ client command, options, that sets Z39.50 options.
713 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
714 options from a string of tokens (one token for each option bit).
716 Update SRW diagnostic code messages.
718 --- 2.0.9-5 2004/01/07 Debian/Windows
720 Handle user defined stylesheet for SRW/SRU.
722 --- 2.0.9-4 2004/01/06 Debian/Windows
724 Fix bug in decoding of Content-Length.
726 --- 2.0.9-3 2004/01/06 Debian/Windows
728 Fix a bug with decoding of XML packed records.
730 --- 2.0.9-2 2004/01/05 Debian only
732 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
734 Fix bug in SRW/SRU diagnostics decoding.
738 Fixed bug in Generic Frontend Server which could drop records exceeding
739 preferred message size. Reported and fixed by Irina Dijour.
741 Fixed calculation of package size for structured records in Generic
742 Frontend Server. Reported and fixed by Irina Dijour.
744 Fixed namespace for SRW/SRU diagnostics.
746 Fixed SEGV in yaz-client that occured for HTTP connection errors.
750 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
751 this version is incompatible with version 1.0 and older YAZ SRW/SRU
754 CQL changes to reflect recent changes to the specification:
755 * Documentation talks about context sets instead of index sets.
756 * Documentation talks about indexes instead of qualifiers.
757 * The CQL-to-PQF transformer's configuration file now uses
758 "index.set.name = <attributes>" instead of the old form
759 "qualifier.set.name = <attributes>". (Both forms are still
760 understood but the latter is deprecated.)
761 * CQL terms with no explicit index specified are now interpreted as
762 cql.serverChoice instead of srw.serverChoice (which of course
763 behaves exactly the same.)
767 MARC conversion can now generate ISO2709 output in another
768 character set. yaz-marcdump uses this facility if you invoke it
771 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
772 functions from there can be used from C++.
776 Frontend server now transfers memory from decoded packages to stream
779 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
780 references to show up.
782 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
783 the ZOOM Abstract API. The older names for the same options are still
784 also supported for the benefit of old applications.
786 ZOOM-C supports "implementationId" and "implementationVersion" options
787 to go along with "implementationName". These allow the user code to
788 specify identification strings to be sent to servers.
789 Add OID for the new ExtLite attribute set.
791 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
792 as requested/supplid by Ere Maijala <ere@atp.fi>
794 For generic frontend server, reverse the order of
795 "toolkit-supplied / application-supplied" strings sent as implementationId,
796 Name and Version. Also, remove the spaces around the slash. This brings
797 the GFS in line with the behaviour of ZOOM-C on the client side.
799 Add function ZOOM_scanset_display_term.
801 yaz-client shows scan displayTerm if present.
803 Utility yaz-iconv is now installed by default along with the man page
806 Extend configure check for OpenSSL to use pkg-config where available (such
809 Incorporate patch by Morten Bogeskov which allows a Unix file socket
810 server to specify uid/gid/mask for socket using the format
811 unix:[user=uid,][group=gid,][umask=mask,]file=path
812 If file= is omitted the existing format is assumed, e.g.
814 in which case the mask is 0666 (rw for everybody).
816 Major restructure of YAZ source. All source in libyaz is in src directory.
817 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
818 util (utility programs such as ASN.1 compiler, yaz-marcdump).
820 Added man page for utility yaz-marcdump (used to be called marcdump).
821 yaz-marcdump is installed by 'make install'.
823 Fixed a memory leak in Generic Frontend Server that occurred when decoding
824 of incoming package failed.
826 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
828 Change prototype of odr_perror: add const to message string.
830 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
832 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
833 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
834 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
835 DNS lookup. There should not be any compatibility problems with this
836 assuming that blocking=1 or 0 is used.
838 Fix bad reference in UNIX comstack in function cs_addrstr.
840 Fix for compilation on AIX.
842 The generic front-end server (server/seshigh.c) now supports returning
843 Init diagnostics to the client in User-information-field, in
844 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
849 Allow any CQL relation (not just all,any,exact,scr).
851 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
852 that features the same UI.
854 Implemented command update0 in YAZ client which is equivalent to
855 update but uses old of Ext Update ASN.1.
857 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
858 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
859 Previously no OID was used for this info.
861 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
862 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
863 returns 'malformed search term' otherwise.
865 SortResponse member resultCount now set to NULL in sort handler of
868 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
871 Add three new utility functions for translating OIDs between various
872 formats -- symbolic name such as "Usmarc", minus-1-terminated int
873 arrays and dotted strings such as "1.2.840.10003.9.5.1":
874 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
875 char *oid_to_dotstring(const int *oid, char *oidbuf);
876 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
878 Reverted modifications for ES Update definition for z_IU0Update
879 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
880 is back to YAZ 2.0.2.
882 String value attributes for CCL parser.
884 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
885 which their FirstSearch server returns in Init responses, sometimes
886 carrying useful diagnostic information when Init fails. This has the
887 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
888 "z39.50/oclcui.asn", where its definition is somewhat different from
889 what OCLC document on their web-site, as required to interoperate with
892 Support for anonymous authentication in yaz-client. Use the command
895 * Fix the OID of the Index Data-local "admin" Extended Service from
896 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
897 the 1000, which indicates a locally-defined OID, was a mistake.
901 Fix CCL directive @case handling so that it affects string match for
902 both CCL keywords and qualifiers.
904 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
905 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
906 Decoder has been updated with ASN.1 changes as listed in
907 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
908 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
909 z_IUUpdate, remains unchanged.
911 ZOOM_record_get may now return a record in a specific character set.
912 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
913 "from" is the character set of record as returned by target. "to" is
914 the character set to be returned. If omitted, "to" is UTF-8.
916 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
918 New ODR utility, odr_getelement, which returns name of element for
919 which encoding/decoding failed.
921 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
922 in cases where a required element was omitted.
924 Bug fix: some MARC8 sequences were not converted.
926 New ZOOM option "step" which specifies number of records to be
927 retrieved in one chunk. Used in conjunction with "start" and "count".
929 SRW support for yaz-client. Use scheme http: to use it, e.g.
932 yaz-client no longer does (un)intelligent character set conversions
933 by default. Can be enabled with charset and marc_charset commands.
935 xmalloc trace fix for 64-bit systems such as DEC alpha.
937 Solaris 2.6 compile fix.
939 New function, cql_strerror() translates SRW error codes, as returned
940 by cql_transform_error(), into human-readable English strings. Used
941 in yaz-client diagnostics when appropriate.
943 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
944 converts it into a type-1 query which is sent to the server. This
945 makes CQL available for use with all Z-servers, as opposed to the tiny
946 minority that can handle CQL queries themselves.
950 New Debian package layout similar to the Redhat Package layout.
952 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
953 and search result respectively.
957 Redhat package is now several packages: libyaz (runtime libraries),
958 libyaz-devel (development and documentation, and yaz (utility programs).
959 Package spec file by Morten Bøgeskov.
961 New member 'schema' in struct bend_fetch_rr which the name of requested
962 schema (SRW/SRU) for record (or NULL if none was given). The fetch
963 handler MAY set this to reflect the schema of the returned record.
965 New member 'display_term' in struct scan_entry. GFS now sets member entries
966 and allocates scan entries to be filled by user scan handler. In previous
967 version, entries member was allocated by the scan handler. That still works,
968 but the GFS will ignore member display_term - assuming it was NOT set by
969 the handler. The fact that the GFS now allocates the entries both allows
970 for new members and makes a scan handler easier to write.
972 Fix CQL lex buffer overflow.
974 SRW/SRU recordPacking. For SRW default recordPacking is string. For
975 SRU default recordPacking is string.
977 SRU protocol support for frontend server.
979 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
981 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
983 Added scan for the ZOOM shell (zoomsh).
987 * String Identifers for Schemas (Amendment 5).
988 http://lcweb.loc.gov/z3950/agency/amend/am5.html
989 Old definition for schema
990 Odr_oid *schema; /* OPT */
995 Z_InternationalString *uri;
996 #define Z_Schema_oid 1
997 #define Z_Schema_uri 2
1000 * resultCount parameter to Sort Response (Amendment 1).
1001 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1003 Support for SRW 1.0 over HTTP. This is an optional feature and
1004 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1007 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1008 on the same port. SRW SearchRetrieveRequests are mapped
1009 to bend_init,bend_search,bend_fetch,bend_close.
1011 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1013 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1014 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1016 ZOOM connections are SRW based if schem http is used for hostname
1017 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1018 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1020 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1021 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1022 distance=n, order=true/false, relation=le, prox unit=word. If
1023 n is omitted, distance 1 is used.
1025 Fixed problem with C compiler include path in wrong order.
1027 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1028 on Solaris. Patch from Ko van der Sloot.
1030 New MARC decode API. All new functions operate on a yaz_marc_t
1031 handle. The most important new functions are: yaz_marc_create,
1032 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1033 decode and destroy respectively. Decoder can produce formats
1034 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1035 include/yaz/marcdisp.h.
1037 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1038 to UTF-8, UCS-32, wchar_t or Latin-1.
1040 * Prototypes for yaz_iconv_-functions moved to separate header
1041 include/yaz/yaz-iconv.h.
1043 Make a few private functions 'static' in unix.c. This prevents
1044 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1046 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1047 are set when Init Response is received.
1049 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1050 but returns diagnostic set as well.
1052 New function yaz_strerror which is a portable wrapper for
1053 strerror/strerror_r/GetLastMessage.
1055 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1056 is returned for MARC. If type is "oai", then OAI MARC is returned.
1058 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1061 --- 1.9.2 2002/11/26
1063 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1065 Fix bad race conditions on SIGTERM and terminate gracefully in
1068 Move retrieval (data1) module to Zebra since nobody seems to be
1071 Add GRS-1 render for ZOOM using same format as yaz-client.
1073 --- 1.9.1 2002/10/05
1075 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1077 Fix broken ESpec handling in data1 module.
1079 SGML reader parses comments and makes them part of the data1 tree.
1081 Added several type casts so that YAZ compiles as C++ code.
1083 ZOOM didn't handle PDU encoding failures properly.
1085 Added more Bib-1 diagnostics (approved extensions).
1087 GNU configure: better check for iconv.
1089 More portable use of accept, getpeername. Check for socklen_t. Use
1090 int/size_t if socklen_t is not defined.
1094 PQF parser rejects bad queries - including those with extra
1095 characters in them. PQF parser used to silently ignore that.
1096 Cleaner API for PQF added, which allows you to get detailed
1097 error information for bad queries (see yaz/pquery.h).
1099 Fixed bug in ZOOM_record_get for type "database".
1101 Implemented mini iconv library supporting conversions between
1102 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1104 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1106 --- 1.8.9 2002/08/20
1108 Fixed ZOOM C record cache so that preferredRecordSyntax and
1109 elementSetName is used to check for already fetched records.
1111 --- 1.8.8 2002/08/02
1113 Added three members in bend_initrequest structure to facilitate
1114 character set negotiation.
1116 Fixed a bug in frontend server that could cause indefinite
1117 loops under rare conditions.
1119 Revised character set utilities (charneg.h) so that encoding
1120 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1122 For PQF, directive @term <type> sets term type for Scan/Search.
1123 Here <type> is general, string, numeric, null. The term type
1124 is inherited - just like @attr.
1126 New call odr_set_charset that sets character set conversion for
1127 international-strings on a ODR stream. Prototype is:
1128 int odr_set_charset(ODR o, const char *to, const char *from);
1129 The InternationalString is still represented as C string in YAZ
1130 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1131 won't). On the protocol level, you can use any encoding.
1133 Support for UNIX sockets in ZOOM.
1135 Solaris recv sometimes returns errno == ENOENT. It is treated as
1136 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1138 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1139 both client and server. Code by Morten Bøgeskov.
1141 --- 1.8.7 2002/05/22
1143 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1144 that they can be used directly from Visual Basic. You must recompile
1145 your windows APP if you're using ZOOM.
1147 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1148 Commands "lang" and "charset" sets language and character set respectively.
1149 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1150 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1152 Attributes from multiple CCL fields may be OR'ed rather than merged
1153 using directive "@field or". Fields are still merged by default -
1154 equivalent to "@field merge".
1156 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1159 Fixed bug in zget for parameter ExtendedServicesResponse.
1163 --- 1.8.6 2002/03/25
1165 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1167 Client displays USR.1:SearchResult-1 (hits per term).
1169 Additional Search Info for search in Generic Frontend Server.
1171 Fixed CCL parsing of "field=s".
1173 WIN32 installer - using the excellent NSIS software from nullsoft.
1175 Fixed CCL parsing of "field = - <number>".
1177 Added function yaz_marc_decode that decodes MARC for line mode
1178 display or XML (similar to that used by JZKit).
1180 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1181 Z39.50. But ISO/ILL was, however.
1183 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1184 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1186 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1187 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1189 --- 1.8.5 2002/02/03
1191 New YAZ client features: Command completion and new commands:
1192 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1193 Code provided by Jacob Poulsen.
1195 New call oid_trav, that visits all registered OIDs via callback.
1197 Function ZOOM_record_get now returns const char pointer rather than
1198 void pointer. It saves a lot of type casts.
1200 For YAZ client, command "auth" now allows you to set authentication
1201 in IdPass style. It is enabled when three tokens are given - order
1202 is user, group and password.
1204 Fix memory leaks in MARC record handling for ZOOM.
1206 New option for YAZ client, -k <kilobytes> that sets
1207 maximum record size. Similar to -k option for generic frontend
1208 server and yaz-ztest.
1210 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1212 Prefix query parser reports "fail" when bad attribute set is given.
1214 Fix in MARC decoder. Proximity logging. Fix for attribute set
1215 in scan handler for server. Patches by Shigeru Ishida.
1217 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1220 Configure option --with-openssl=<dir> now works when a directory is
1221 specified. Patch provided by Morten Bøgeskov.
1223 New option for YAZ client, -u <auth>, that sets authentication.
1225 ZOOM fix: error information was sometimes "missing", since error
1226 was cleared/reset too when it shouldn't.
1228 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1230 --- 1.8.4 2002/01/04
1232 Scan for ZOOM API. New object ZOOM_scanset. New functions
1233 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1234 ZOOM_scanset_destroy.
1236 New ZOOM function, ZOOM_connection_last_event, that returns type
1237 of last event (such as "receive data", "send data", "apdu received",
1240 New ZOOM option, schema, that specifies schema for retrieval.
1242 New CCL feature. Qualifiers can be aliases for one or more
1243 other qualifiers (if more than one is given, OR is used).
1245 ZOOM uses named result sets if target supports it.
1247 Two new YAZ client commands: . (dot, which sources a script of YAZ
1248 client commands), and ! (to execute shell command.). Implemented
1251 Working on Debian packages.
1253 --- 1.8.3 2001/11/19
1255 YAZ client enables named result sets only if target supports it.
1257 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1259 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1260 with key="host" to get same result.
1262 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1263 Function Z3950_resultset_record(s) returns references to records
1264 "owned" by resultset. To become owner use Z3950_record_clone.
1266 Function z_ext_record handles Extended Services. Thanks to
1269 --- 1.8.2 2001/11/12
1271 CCL Parser fix: ignore token comma when dealing with and-lists.
1273 Documentation updates for COMSTACK.
1275 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1276 Changed prototype Z3950_records. For some functions, int parameters
1277 were changed to size_t.
1279 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1282 New MARC decode/display function, marc_display_exl, which properly rejects
1283 non-ISO2709 records. YAZ client uses it.
1285 --- 1.8.1 2001/10/29
1287 Fix bug: local attribute set wasn't set correctly in PQF strings.
1291 * Old Z39.50 codecs no longer supported.
1293 Added ZOOM C binding. See http://zoom.z3950.org/
1295 Renamed states for COMSTACKs to avoid confusion with events.
1297 Implemented cs_look and proper cs_rcvconnect.
1299 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1301 Configure detects POSIX threads on OpenBSD.
1303 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1304 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1306 When error is returned from present handler, non-surrogate diagnostic
1307 is returned in present response (and fetch handler is no longer called).
1309 * Minor adjustments to pquery parser (PQF). Token characters may be
1310 escaped by using backslash (C-style).
1312 PQF parser allows string attribute values to be specified. For @attr,
1313 non-numeric characters after the equal-sign are treated as strings
1314 (e.g. @attr 9=title).
1316 CCL trunction character may be defined (@truncation in file)
1318 * function zget_ExtendedServicesRequest sets waitAction to
1319 waitIfPossible (was wait).
1321 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1324 CCL operator names may be set in field definition files (CCL_bibset).
1325 See ccl/bib1 for an example.
1327 Fixes in ASN.1 compiler for C++ compatibility.
1329 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1330 and "op_or" to avoid conflict with C++.
1332 Fixed problem with GNU readline detection on Redhat 7.0.
1334 Added step-size for Scan backend handler.
1336 Fixed bug that made the frontend server crash when no attribute
1337 set was specified for scan.
1339 Front-end server automatically switches to original working directory
1340 when installed as an NT service. Previously -w had to be specified to
1343 Added extended attributes for retrieval module (data1), so that data1
1344 records carry d1_readXML/SGML attributes. d1_read also supports
1345 null-data rules ( <tag/>)
1347 On UNIX when POSIX threads are available, a separate library libyazthread
1348 is created. Programmers should link with that library and the yaz library
1349 when using threads. The reason for the split was that some applications
1350 on Linux, such as Apache, doesn't work well when using shared objects that
1353 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1354 (or any frontend server) in SSL mode by specifying ssl: followed by
1355 address. Only tested on UNIX.
1357 Added feature for CCL module. Virtual structure s=al or s=ol generates
1358 and-list and or-list respectively instead of phrase search.
1362 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1363 log_mask_str. This was done to avoid name conflicts with other libraries
1364 (such as other PHP extensions).
1366 Added raw OID member for preferred record syntax (request_format_raw)
1367 and returned record syntax (output_format_raw) for backend fetch method.
1369 Config file yaz-config now accepts options so that it returns specific
1370 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1372 Shared library support for UNIX using GNU libtool.
1374 * Modified backend interface. Request/Response struct's replaced by
1375 one read/write C struct. For example bend_fetchrequest and
1376 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1377 Every handler - even search has to be registered in bend_init
1378 handler. This means that the YAZ library no longer refers to
1379 external functions and it makes it possible to make the whole
1380 thing a single DLL/SO.
1382 Added Segment handler for backend server.
1384 Added Zmbol/Zebra administrative functions to YAZ client.
1386 Threaded frontend server on UNIX (when POSIX Threads are available).
1387 Starting the server with option -T enables multi-threading.
1391 Added configure option --enable-comp/disable-comp to control use
1392 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1393 located in sub directory asn.
1395 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1396 in ${exec_prefix}/bin along with the other programs yaz-client and
1399 GNU automake used to maintain makefiles.
1401 Added several OID's.
1403 Changed retrieval module so that we can load records with no abstract
1404 syntax defined. Tagpaths in these records are fully composed of string
1407 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1411 On UNIX, the generated makefile now supports a proper 'make install'.
1412 The prefix can be set via GNU configure to set the install location
1413 (default is /usr/local).
1415 * YAZ programs client and ztest were renamed to yaz-client and
1416 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1417 locations, such as /usr/bin,/usr/local/bin,etc.
1419 * YAZ Header files were moved from include to include/yaz. YAZ Header
1420 files are referred to as include <yaz/log.h> rather than <log.h>.
1421 The YAZ include path (-I ..) is therefore the same as before. Programmers
1422 should update their #include statements or use -Ipath/include/yaz
1423 instead. The main motivation for doing this change is that YAZ header files
1424 can be installed in "standard" locations /usr/include,/usr/local/include
1425 without introducing conflicts, since ALL YAZ header files are stored
1426 in subdirectory yaz (under /usr/include for example).
1428 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1429 rather than project/workspace files. We switched because project files
1430 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1433 Changed name of logging function, logf, to yaz_log, to prevent name
1434 clash with some math-log functions. The YAZ header log.h defines logf
1435 to yaz_log (#define) so there should be no incompatibilities by this
1438 Added bend_start/bend_stop handlers for server. These handler are
1439 called on start/stop of server. For windows they are called whenever
1440 a service is started/stopped.
1442 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1443 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1444 in util/yc.tcl. The auto-generated C code structures are, in a few
1445 cases, incompatible with the old decoders. There are differences in the
1446 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1447 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1448 The preprocessor variable ASN_COMPILED is defined when the compiled
1449 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1450 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1451 wish to use the old encoders/decoders you can specify --disable-yc
1454 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1455 version so that it supports both new - and old version of DB Update
1457 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1458 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1459 change. The name parameter can be set to 0 in which no name is specified
1460 for the construction. The macros odr_implicit and odr_explicit sets name
1461 parameter to zero for the construction involved. New macros
1462 odr_implicit_tag and odr_explicit_tag are similar to the others,
1463 except that a name parameter is added. For programmers' that don't use
1464 ODR they probably only need to change the call to z_APDU and z_External.
1466 Added access control facility by interfacing the TCP wrapper library.
1467 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1468 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1469 name of the daemon and enables the access control as specified in
1470 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1472 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1473 den Dool <H.M.vdnDool@kub.nl>.
1475 Added reference ID parameter to most functions in server API - refer
1476 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1478 Changed name of ccl library to libccl.a (was ccl.a).
1480 Fixed bug in decoder for Explain (Category TargetInfo).
1482 Added support for GNU readline in client. Thanks to Jacob Poulsen
1483 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1485 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1486 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1487 IMPLEMENTATION! This change was made to the development version before
1488 the ZIG decided to retract the amendment. If any users MUST be
1489 compatible with the original Update definition, PLEASE CONTACT US, and
1490 we will include a separate definition corresponding to the old Update
1491 ES. Note that because of the change to the ASN.1 of the
1492 TaskPackageRecordStructure we cannot define a single structure that
1493 will support both versions.
1495 * Added const modifier to buffer parameter for some ODR/BER encoding
1496 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1497 completeWAIS, odr_dumpBER.
1499 Fixed bug in client.c which caused a crash when a scanResponse didn't
1500 contain positionOfTerm.
1502 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1503 * will cause an error in a client if a non-YAZ target sends both a
1504 * list of Scan entries and non-surrogate diagnostics.
1506 Retrieval module enhancements. Tag sets may be typed in the reference
1507 to it. From the .abs-file the "tagset" directive takes a third optional
1508 integer type for the tag set referenced. From a .tag-file the "include"
1509 directive takes a third optional type as well. The old "type" directive
1510 in the tag set itself is still recognized but acts as the default type
1513 Backend interface change. Individual Scan terms returned from bend_scan
1514 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1515 in include/backend.h.
1517 Retrieval module enhancements. Multiple tag sets and attribute sets may
1518 be specified in abstract syntax specs. Revised the error/warning for
1519 logging messages reported by the retrieval module when reading the
1522 Object Identifier system (oid_..) changed. The API is backwards
1523 compatible but the oid-routines now allocates new OID's when needed.
1524 Raw OID's may be specified in oid_getvalbyname.
1526 YAZ now uses GNU configure to generate Makefile(s).
1528 * Minor changes in some of the member names of DeleteResultSetRequest and
1529 DeleteResultSetResponse. See include/proto.h.
1531 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1532 and added member 'languages' in TargetInfo (which was missing).
1534 Changed the way attribute sets are handled in the retrieval
1535 module. These are now cached, just like the abstract syntaxes
1538 Changed YAZ so that it links with compiled ASN.1.
1540 Added Explain-schema definitions and mapping routines. The following
1541 Explain categories have been implemented: AttributeDetails,
1542 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1544 Fixed minor bug in Windows version of Server Library.
1546 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1548 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1550 Added EXTERNAL: UNIverse Resource Report (non-standard).
1552 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1553 ENUMERATED and SET OF.
1555 * Added 'const' to some of the char pointer arguments for the
1556 functions, data1_read_node, data1_getelementbytagname,
1557 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1560 Fixed bug in data1_insert_taggeddata - the last_child member of
1561 parent wasn't initialised.
1563 * Changed data1_read_record and data1_read_node so that the supplied
1564 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1565 doesn't refer to any parts of the "SGML"-buffer.
1567 Fixed bug in server library (Windows version of statserv_remove).
1569 * Changed code so that it compiles as C++. The type definition
1570 of Odr_fun which is a member of Odr_arm was changed. The result is,
1571 that an explicit typecast is needed for the fun pointer when
1572 using Odr_arm - as in:
1573 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1575 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1577 Implemented the new structured date and time definition as approved
1578 by the ZIG. Added schemaId element to the specificTag in Espec-1
1579 (also approved at the last ZIG). Thanks to RVDM.
1581 Added some Object identifiers (RVDM).
1583 Changed the Update Extended Service (RVDM).
1585 Added command "refid" to client which specifies referenceId for
1586 the following requests.
1588 Implemented extended service handling for server. See ztest.c
1589 for an example as well as backend.h. New handlers are registerd
1590 in the Init handler.
1592 * Changed interface for sort in server.
1594 Added new members to statserv_options_block. It allows a server
1595 to read options from another source than just the command line. Thanks
1596 to Charles Woodfield.
1598 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1599 renamed to zboolean. Some C++ compilers complained about the name.
1601 Minor changes to gils.abs. Added index 's' (sort) on title
1602 and date/time-last-modified.
1604 --- 1.4pl2 1998/1/30
1606 Fixed bug in server library regarding inetd mode (-i). This bug
1607 was introduced by release 1.4.
1609 --- 1.4pl1 1998/1/29
1611 Added sort facility in client and backend server interface.
1613 Fixed problem with dependencies in Makefile(s).
1615 Fixed bugs for encoders/decoders of extended services and
1618 Implemented sub-tree feature for schemas. Sub-trees are
1619 referenced in *.abs-files. See explain.abs for an example
1620 of the use of this feature.
1622 Modified bib1.att; local attributes for ANY didn't include
1623 ANY itself (only affects use of the retrieval module).
1625 Fixed bug in plain SGML reader in function data1_read_node:
1626 tags with prefix "var" was incorrectly interpreted as variants.
1628 Added feature "sub-schemas" to enable references to - and definitions
1629 of - group of elements.
1631 * Removed member parent from type data1_element (in data1.h).
1633 Implemented function odr_nullval() that returns the value of
1636 * Removed member num_children from data1_node (in data1.h).
1638 Made NT service interface part of the server library. The
1639 function statserv_main uses the NT service when required and
1640 calls the statserv_start / statserv_close routines.
1642 Routine zget_SearchRequest and zget_PresentRequest fills
1643 resultSetName/Id member with "default" instead of "Default".
1645 Fixed memory leak in server. Request queue member wasn't freed.
1647 Fixed nmem_exit so that memory is freed.
1651 Revised the CCL parser utility to be thread safe.
1653 Added function, oid_ent_to_oid, to replace the function
1654 oid_getoidbyent, which is not thread safe.
1656 * Added nmem_init and nmem_exit to initialize and release
1657 NMEM resources. Function nmem_init should be called once in the
1658 initial thread before NMEM/ODR is used. statserv.c and client.c
1659 have been changed accordingly. The change was necessary to make
1660 NMEM thread safe. The NMEM memory pool is shared amongst threads
1661 in a process. Unix-based applications will still work fine without
1664 Added NT Services interface for the the Z39.50 (statserv) Server.
1665 Refer to the ztest.c source on the usage.
1667 Windows 95/NT port using MSVC5.0. Project files are included in the
1670 * Defined new 'global' handle for the retrieval (data1) system. The
1671 new handled, data1_handle, describes the state of the data1 system.
1672 This handle is passed as first argument to virtually all
1673 data1 related routines. The functions data1_create and data1_destroy
1674 creates and destroys a data1 handle respectively.
1676 Added ODR encode stream member to all backend request structures
1677 init, search, scan etc. This stream should be used to allocate all
1678 memory used for the response when thread safe operation is needed.
1680 Changed the comstack utility, cs_addstr, to be thread safe. The
1681 returned hostname string returned by the function is now part the
1684 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1685 function. The cs_straddr takes a COMSTACK handle as argument, so this
1686 function must be used after cs_create and before bind/connect.
1687 This function is thread safe.
1689 Moved test server to 'ztest' directory - generic server code still
1690 in 'server' directory.
1692 Made prefix query (pquery.c) utility thread safe.
1694 Added new function modifier YAZ_EXPORT to 'export' public DLL
1695 functions when using windows (see include/yconfig.h).
1697 Added definitions to the OID database (util/oid.c) (RVDM).
1699 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1701 Added call to ccl_rpn_delete in client program.
1703 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1704 release of RPN structure.
1706 Added support for C++, headers uses extern "C" for public definitions.
1707 With input from RVDM.
1709 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1710 Thanks to Ronald van der Meer (RVDM).
1712 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1714 Added support for private extensions to the OID database
1715 (oid_setprivateoids()). Thanks to RVDM.
1717 Added optional, physical ANY (key replication)
1719 Fixed null-reference problem in GRS-1 output filter.
1721 Proximity operator added to Prefix Query Format (PQF).
1723 In test client command "base" accepts multiple databases.
1725 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1729 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1731 Smallish bug-fixes in the new encoders/decoders (explain).
1733 Bug fixed in DeleteRequest.
1735 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1737 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1739 Added SOIF syntax (using private OID for now) to retrieval module and client.
1741 Added Update extended service.
1743 Added SearchResult-1 additional info structure.
1745 Added optional CCL (ISO8777) interpreter as separate module. Available
1748 --- 1.2 1996/6/10 (1st anniversary release)
1750 Added Summary record syntax. Lightly tested.
1752 Added OPAC record syntax. Untested.
1754 Added ResourceReport service encoders/decoders. Untested.
1756 Fixed bug in z_Unit - wrong tagging on unitSystem.
1758 Fixed bug in the DiagRecs decoder.
1760 Added options for max PDU size and session timeout to frontend-server.
1762 Added documentation of query-language parsers and other supporting utilities.
1764 [frontend-server] Added Attribute set to the bend_scanrequest API.
1766 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1767 surrogate diagnostics were generated.
1769 [retrieval] Allow multiple local values for attribute.
1771 [retrieval] Allow multiple attributes per element in .abs files. index type.
1773 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1775 --- 1.1pl2 1996/4/10
1777 Minor changes, mostly specific to Zebra's requirements (retrieval)
1781 Repaired bug in frontend server when running multiple listening
1782 endpoints in dynamic mode.
1784 z_External() now won't break if a known, ASN.1 value comes encapsulated
1785 in an octet-string. The value will pass through unmodified in an Odr_oct.
1787 Added a bit of code to the demo client to decode & display
1788 ASN.1-structured records represented in the octet-aligned branch of
1789 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1791 Added z_ext_getentbyref() to the ASN module. Doc updated.
1793 * Completed the SCAN definition in the ASN module. This may break SCAN
1794 code based on older YAZ-versions at compile-time. The fix is easy -
1797 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1798 under the SCAN definition. Remember to initialize this, server-people.
1800 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1801 that this does not extend to ODR and ASN.
1803 Comstack allows insertion of established socket (primarily for
1804 inetd-operation of servers). Doc updated.
1806 Front-end server can now start from the inetd in TCP mode. Doc
1809 --- 1.0pl4 1996/1/24
1813 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1814 the rank and record number.
1816 Adjustments to the frontend server.
1818 Fixed diagnostic BER dumper. It ignored the file argument.
1822 Various changes to retrieval module.
1824 Changed the union discriminators of the protocol files from enums to
1825 ints paired with #defines.
1827 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1830 *Changed operator in the RPN structure to 'roperator', again to avoid a
1833 Fixed problems in Explain decoders/encoders.
1835 --- 1.0pl2 1995/12/6
1837 Memory bug in log module fixed.
1839 --- 1.0pl1 1995/12/5
1841 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1843 Bug in Explain DatabaseInfo module fixed.
1845 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1849 The shift to v1.0 signals that we now consider the *core* functionality
1850 of YAZ reasonably stable (the core being more or less equivalent to
1851 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1852 tested (Explain not at all - though that will happen soonish).
1854 Minor changes to code to support Windows port.
1856 Various minor changes after we're getting to use GRS-1 & co. more.
1858 Added Espec-1 format.
1860 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1861 of the protocol and it cannot be selected when encoding (maps into 'string'
1862 when decoding). Needed to talk to some servers.
1864 Demo client can request simple element set names.
1866 Added Diagnostic Format encoders/decoders.
1868 Added simple Close handling to frontend server (no hooks for resource
1869 reporting yet), and demonstration client.
1871 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1873 --- 1.0b3 1995/08/24
1875 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1876 handled incorrectly when records were requested in the searchResponse. This
1877 will only affect you if you use the frontend-server.
1879 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1880 Test-client will ask for and print GRS1. Ztest will return dummy records
1883 Added Explain encoders/decoders to the service-level API. Untested.
1885 Added Extended Services: Item Order encoders and decoders to the Service-
1886 level API. Untested. We could use a recent copy of the pertinent bits
1887 of the ILL protocol to add those bits.
1889 Added diagnostic format 1 encoders/decoders to the service-level API.
1892 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1893 odr_cons.c, which causes a more correct output.
1895 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1896 was always set to 0 when no records were requested in the searchRequest.
1898 * Added better external-handling. This shouldn't harm old code that
1899 *encodes* externals. It can break code that looks for a
1900 'single-ASN1-type' representation, since those types that are known
1901 are now decoded immediately. Look at the SUTRS sample code in
1902 seshigh.c and client.c. Documentation updated.
1904 Handling of structured records in bend_fetchresponse. Length -1 marks
1905 structured record, type is deduced from format field.
1907 --- 1.0b2 1995/06/27
1908 Fairly quick maintenance release to add SUTRS support.
1910 Fixed handling of SUTRS records in the demonstration client.
1912 * Added format field to the bend_fetchrequest and bend_fetchresponce
