3 Fixed bug #775: char conversion does not handle Alternative UTF-8
6 Implemented function yaz_marc_read_line which parses MARC line format
7 records. There is a wealth of formats out there. So far, this function
8 reads line records produced by yaz_marc_write_line.
10 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
11 more generic and easier to remember(!) options: -i format and -o format
12 which specifies input format and output format respectively - where
13 format is one of "marc", "marcxml", "line", "marcxchange".
15 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
16 does not print anything except warnings for records.
18 For yaz-marcdump, added support for MARC split into files (-s) with a given
21 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
22 spec, at http://www.loc.gov/standards/sru/record-update/
23 This has changed the binary layout of the following structs:
24 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
25 bend_update_rr . Patch by Ko van der Sloot.
27 Added GFS utility function bend_assoc_is_alive which returns 1 if
28 association is still alive (client is connected); 0 otherwise (client
29 closed connection). This allows busy servers to stop working for
32 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
33 been a separate piece of software. This version of ziffy has been modified
34 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
36 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
38 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
39 Client code may now interrogate options such as "init_opt_sort" to
40 find out whether the server claims to support various options.
44 Added utilities yaz_{set,get}_esn to set/get element set name from
47 Removed the build of libyazthread.la. The libyaz.so is the threaded version
48 of YAZ and has been so since YAZ 2.1.10.
50 Implemented ZOOM_record_error which returns error information for
51 record (surrogate diagnostic).
55 Updates for SRU Update by Ko van der Sloot:
56 1. Changed name from "operation" to "action"
57 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
58 versions in the code, marked as 'backward compatible'.
59 3. Added diagnostics for SRU Update.
61 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
63 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
65 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
67 For GFS, fixed problem with SRU diagnostic 'First record position out of
68 range' being issued for 0 hits.
70 zoomtst10 part of Windows Build.
74 Implemented yaz_filepath_comp which splits a path into file path
75 components (required by Zebra 2.0.3+).
77 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
78 BSD inspired license until now so this should not have any real impact on
79 anybody. See http://www.opensource.org/licenses/bsd-license.php
81 Fixed bug #687: Missing log lines.
83 Fixed bug #678: CQL to PQF translation does not preserve double-quote
86 Fixed bug #689: SRU diagnostics to be added.
88 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
89 whether a connection is idle (no more work do do).
93 Change type of optval from long to int for invocation of setsockopt with
94 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
96 Added support for specifying the max log file size for the Generic
97 Frontend Server. The size is given with option -r.
101 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
103 --- 2.1.30 2006/09/17
105 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
108 Fixed bug in Generic Frontend Server that could cause a server to stop
109 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
111 For the generic frontend server, the maximum record size is used as maximum
112 size of incoming packages (SRU + Z39.50). The value until was previously
113 only used in Z39.50 Init negotiation and, later, in a session controlled
114 sizes of records returned. This is controlled using -k option. It can be
115 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
117 --- 2.1.28 2006/09/04
119 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
122 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
124 New option for yaz-marcdump -lpos=value which allows setting a portion
125 of MARC header to a certain value.
127 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
129 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
130 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
132 --- 2.1.26 2006/08/15
134 Fixed problem with SRU mode type (soap, get, post) for yaz-client
137 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
139 --- 2.1.24 2006/08/08
141 Fixed MARC ISO2709 encoding routines to deal with character set
144 Minor changes to GFS logging. Database included in search request log
147 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
148 cached/multiple records.
150 Shared libraries are built by default on Unix+configure.
152 Changed cql2pqf transformation to use a different evaluation order. The
153 new order is: always, relation, structure, position, truncation, index
154 and relationModifier. Old order was: always, relation, relationModifier,
155 structure, index, position, truncation. Note that the the latter ones
156 override former ones for identical attributes.. The new scheme means that
157 it is possible to override any existing attribute with a relationModifier.
158 And also that it is possible to override everything for the index rule
159 (except the ones listed in relationModifier). No order is perfect but this
160 one, we believe, covers more real cases.. The "always" should have been
161 called "default", since the attributes there can be overridden with all
164 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
165 compilation phase, but also for yaz-config --cflags output. This allows
166 us to have public headers with Libxml2 stuff in them . It should also,
167 eventually, make Libxml2 checks redundant in packages using YAZ, such
170 --- 2.1.22 2006/06/15
172 Changed SRU update structure bend_update_rr so that SRU diagnostics are
173 stored in uri, message and details.. Previously diagnostics were stored
174 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
175 compatibility.. but he's probably the only one affected, so.
177 Added support for CCL, compiled on the client side, in ZOOM-C. This
178 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
179 input; the resulting query objects can be used for for searching with
180 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
182 YAZ' configure searches for OpenSSL by default.
184 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
185 SL_CTX_use_certificate_file. See
186 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
187 for more info. Thanks to Ko van der Sloot.
189 --- 2.1.20 2006/06/02
191 Bug #600: SRU GET, POST support for yaz-client. Introduced
192 command 'sru' which selects method SOAP/GET/POST.
194 Allow missingValueAction to be specified for the sortspec string -
195 function yaz_sort_spec. By default, the missing value action is null.
196 Use ! to specify "abort". Use = followed by stringvalue to specify default
199 Ensured that Present-handler (if defined) is called in GFS before any call to
200 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
201 searchRetrieve requests.
203 Documentation for YAZ is now based on the Docbook XML/XSLT using
204 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
205 is no longer depending on jade/openjade or docbook-to-man scripts.
206 PDF is no longer part of the distribution - but can optionally be
207 made using DSSSL/jadetex or FOP.
209 Added retrieval handling support in Generic Frontend Server to support
210 conversion between MARC/XML as well as XSLTtransforms. See
211 etc/yazgfs.xml for an example.
213 Added Authentication support to Generic Frontend Server in SRU
214 mode. Authentication using HTTP Basic is supported, as is the use
215 of 'x-username' and 'x-password' parameters in the request itself.
217 Added support for a new character set MARC8s identical to MARC8 except
218 that it converts combined characters to single Unicode characters in the
219 Latin-1 range (when possible).
221 --- 2.1.18 2006/04/24
223 ASN.1 compiler 0.4: generates brief Doxygen file header for
224 generated .h/.c files.
226 Utility yaz_iconv now supports conversion to MARC-8.
228 New facilities for the MARC module. The reading - and writing of
229 content are separate methods for the yaz_marc_t handle. The following
230 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
231 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
232 format). Write functions have prefix yaz_marc_write_.. The existing
233 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
234 available. Removed support for OAI-MARC and simplexml (not the
235 simplexml from PHP5).
237 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
238 to be returned for this connection.
240 --- 2.1.16 2006/03/31
242 Allow multiple languages and charsets to be specified with
243 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
244 negcharset iso-8859-1,utf-8
246 Translation of proximity nodes from CQL into PQF now works.
248 Moved to automake 1.8, 1.9.
250 Added function yaz_log_set_handler which allows a log handler to be
251 installed. This handler will be called for all log messages. Output
252 to file is also produced; but that can be disabled by passing NULL
253 fname to yaz_log_init_file.
255 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
257 For SRW (including GFS), accept application/soap+xml as content-type
260 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
261 produces NO stylesheet reference even if a default stylesheet is specified
264 --- 2.1.14 2006/03/14
266 Updated Windows package to include yazd.dll + yazd.lib for the
267 Development component.
269 If the environment variable YAZ_LOG is set, then it is used as a
270 string indicating the default level of logging to use if not
271 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
272 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
273 used as before. So, for example, to omit warnings from YAZ logging,
276 cql_transform() now map structure and other attributes before indexes,
277 so that index-specific structures and other attributes can override
278 defaults. So now a combination of mapping specifications such as:
280 index.dc.date = 1=date-modified 4=5
281 does the right thing.
283 cql_transform() now also respects the "always" mapping specification,
284 which establishes an initial set of attributes to be used for all
285 terms except where overridden by more specific attributes associated
286 with the index, relation or modifier.
288 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
289 which mode to use; one of "post", "get" or "soap" (SRW, default).
291 Fixes for yaz_iconv routines: changed trie-based character set conversions
292 to use only non-negative values for bit fields due to Sun's C compiler not
293 supporting negative values.
295 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
296 sequences where not read correctly. Fix by Rustam Usmanov.
298 Updated win/makefile to use options, settings which makes things
299 compile with VS C 2005.
301 --- 2.1.12 2006/02/01
303 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
305 In ZOOM socket code, use select instead of poll on MacOSX.
307 ZOOM-C now support client-side compilation of CQL into RPN that is
308 sent to the server, enabling CQL to be used against all Z39.50
309 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
310 ZOOM_query object, and submit it using ZOOM_connection_search().
311 The CQL-to-RPN translation uses a configuration file, the name of
312 which must be specified in the Connection's "cqlfile" option.
314 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
315 function, which takes as its start-term parameter a ZOOM_query object
316 (which may have had either CQL or RPN set into it).
319 --- 2.1.10 2005/11/29
321 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
322 GFS to support this as well. Backend handler, bend_srw_update, does the
323 update work. Code contributed by Ko van der Sloot.
325 Allow retrieval of Search Result-1 information in ZOOM by the use of
326 options that are attached to a result set. ZOOM documentation updated
329 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
330 UTF-8 conversion. Patch by Raj Patel.
332 Added option -m to GFS to control formatting of timestamps in log file.
334 Added 'exit' as synonym for 'quit' in yaz-client
336 Added support for specifying SRW resultSetId + resultSetIdleTime in a
337 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
338 for the new members. Patch by Ko van der Sloot.
340 Added support for SRU POST. It is supported for content-type
341 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
343 Do not build the separate Multi-threaded (MT) library libyazthread.la.
344 Instead make the library libyaz.la multi-threaded. Threading as a whole
345 can still be disabled by configure option --disable-threads. Previosly,
346 with older GLIBCs there were problems with MT libs under Apache. This
347 has now been fixed a long time ago.
349 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
352 CQL module modified to be case insensitive for relations/indexes/operations.
354 Fixed bug in CQL transform code: incorrect value relationModifieder
357 Added 'show all' command for yaz-client which retrieves all results
360 Added new yaz-client, xmles, which takes a (private) OID and
361 a document to be sent as an extended service request.
363 Describe new yaz-client commands wait_response and set_auto_wait.
365 Increase TCP/IP listener backlog from 3 (which I am guessing was
366 copied from the SunOS manual entry way back when) so SOMAXCONN, so
367 that the socket will queue as many incoming connections as it's able
368 to handle ongoing connections. In other words, it will never now
369 refuse a connection that it would be able to handle merely because
370 it's not got around to accepting() enough of the pending connections
371 yet. This is the behaviour anyway under Linux, where the listen()
372 argument is ignored; but not under BSD and on systems such as
373 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
374 YAZ-based servers should now be uniform across operating systems in
377 yaz-marcdump uses 64-bit file access on some systems. This is enabled
378 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
379 This allows yaz-marcdump to read large MARC batches (>2 GB).
381 Modified all YAZ source files - except the source which is auto-generated
382 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
385 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
386 corresponding to the existing *_setl() function. These allow option
387 values containing arbitrary valuues.
389 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
390 ZOOM_resultset_sort() in new applications. Its behaviour is identical
391 except that it returns an indicator of whether or not the sort
392 criterion was accepted (0 for OK, -1 for invalid).
396 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
397 MARC output rather than returning "new" buffer.
399 yaz-client warns about unknown init options.
401 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
405 Added support for SRW sort in Generic Frontend Server. Patch
406 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
407 sortKeys - or NULL if none is provided.
409 Fixed bug #307: It was impossible to specify indefinite/no timeout
410 for ZOOM_event. Special timeout value -1 now means indefinite timeout
413 Added support for multiple languages and charsets to be specified in
414 ZOOM. Each charset/language is separated by a blank. If negotiation is
415 in effect in init-response, Option
416 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
417 Code based on patch by Vasiliy Osadchuk.
419 Fixed bug #306: infinite recursion that occurred when calling
420 yaz_log_level_init as the first call (before other log level or
423 Fixed bug in scan handling in front end server: if preferred-Position-In-
424 Response was non-present, a NULL pointer referece was performed.
428 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
429 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
430 now defined for all those error codes. So instead of putting 109 in
431 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
432 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
434 Modified the yaz-marcdump utility to skip garbage bytes between MARC
437 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
439 Program yaz-client now exits and produces an error message if multiple
440 Z39.50 servers are specified on the command line (none or one allowed
443 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
448 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
450 Fixed bug #272: Preserve spacing for CCL terms.
454 Added support for virtual hosts and multiple backend servers for
455 the YAZ frontend server. The configution is XML based and
456 support specificition of CQL to RPN mappings and explain information.
457 See section "Virtual Hosts" in the YAZ manual.
459 Extended OPAC display utility. OPAC display utility renders
460 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
461 to supplement yaz_marc_decode_wrbuf.
463 Fixed a bug in MARC decoder that could caused it to crash for some
464 invalid MARC records. More diagnostics and warnings where added in
465 XML output (warnings, etc are stored in comments).
467 --- 2.0.34 2005/02/08
469 Fixes for UNIX domain sockets. Bug #261.
471 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
473 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
474 Added yaz_marc_subfield_str which defines subfield lead string which is
475 used in YAZ_MARC_LINE format. Default string is blank+$. Added
476 yaz_marc_endline_str which defines end of fields string used in
477 YAZ_MARC_LINE format. Default string is newline.
479 Experimental support for MarcXChange. This format can be produced
480 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
481 http://www.bs.dk/standards/MarcXchange.xsd
483 Added yaz-client commands scansize that sets maximum number of
484 entries to be returned by scan.
486 --- 2.0.32 2005/01/11
488 Added support for SRW scan in yaz-client and Generic Frontend Server.
490 * Added whereInList member to SRW Scan Term.
492 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
494 Fixed NMEM system to return aligned blocks on the smallest boundaries
495 that are suitably aligned for all possible types on the particular
496 architecture YAZ is being built for.
498 --- 2.0.30 2005/01/04
500 Fixed numerious warnings that was issued with newer versions of GCC.
502 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
503 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
506 Make YAZ Generic Frontend Server slightly faster.
508 Enhance (and reduce) logging for Generic Frontend Server.
510 Revert YAZ log system so that it flushes every write operation
511 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
513 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
514 instead of LOG_, due to name clash with syslog(3). LOG_ are still
515 present. New applications should define YAZ_USE_NEW_LOG=1 - this
516 will effectively disable old definitions.
518 --- 2.0.28 2004/11/09
520 Added yaz_log_time_format which specifies log format using
523 Added yaz_log_module_level which returns mask for a module. Value
524 is non-zero mask a if module is enabled; zero if disabled.
526 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
527 in include/yaz/cql.h.
529 Fixed bug #176: Dont throw diagnostics on empty SRU args.
531 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
533 Fixed bug #172: RPM builds does not enable SSL.
535 Doxyfile.in part of dist. Doxyfile generated by configure.
537 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
538 are given and the corresponding component does not exist.
540 Extend CCL documentation in YAZ reference. Describe r=r.
542 --- 2.0.26 2004/10/01
544 Fixed MARC->MARCXML conversion to properly deal with
545 fields, subfields, indicators having non-ASCII characters.
547 Fixed MARC->MARCXML conversion so that ASCII control characters
548 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
551 Added YAZ GFS support for conversion from Z39.50 surrogate
552 diagnostics to SRW surrogate diagnostics.
554 Bug fix: YAZ GFS did not return schema in explainResponse.
556 --- 2.0.25 2004/09/30
558 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
559 now converts recordSchema to elementSetName as well as schema URI.
561 Fixed bug in COMSTACK that prevented HTTP request packages from being
564 --- 2.0.24 2004/09/29
566 Added CCL facility r=r "range" which is similar to r=o "ordered" but
567 does not require white-space before and after the dash in a range, e.g.
568 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
571 Fixed a few AC_TRY_LINK configure tests that did not operate properly
572 due to new GCC removing "redundant" code.
574 Added yaz-client commands scanpos and scanstep that sets preferred
575 position and step-size for scan.
577 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
579 Added CCL utility ccl_qual_buf which parses one or more CCL
580 spec lines in a buffer.
582 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
583 of name and value - ignoring empty lines and comments.
585 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
587 Added odr_get_element_path which returns current element path for an
588 ODR handle. This utility is useful in error handling or user-defined
591 Added ODR_PRINT utility odr_set_stream which is is a more generic
592 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
593 to a write function and pointer to close function. The close function - if
594 non-NULL - will be called during odr_destroy.
596 Fixed bug in CCL parser where truncation char was not removed from
597 right side when truncation=both was in effect.
599 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
602 --- 2.0.23 2004/08/11
604 Fix buffer overrun in CQL parser when dealing with proximity (%).
606 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
607 to UTF-8/UCS conversion is now only based on codetables.xml.
609 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
611 --- 2.0.22 2004/08/06
613 Add support for more "commit changes" in ZOOM (uses Extended Services).
615 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
618 Yet another small fix for configure of SSL.
620 --- 2.0.21 2004/05/14
622 Fix SSL libs for configure when --with-openssl=DIR is given.
624 --- 2.0.20 2004/05/10
626 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
628 SSL comstack now uses yaz.pem certificate file on server side
629 by default. Certificate filename can be configured by calling
630 comstack function cs_set_ssl_certificate_file before cs_bind is used.
632 Fix bug regarding multiple calls to ZOOM_connection_connect.
634 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
636 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
637 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
639 ZOOM now allows inspection of X509 peer certificate for verification.
640 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
642 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
643 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
644 as "modular" but it simplifies things.
646 Added cs_get_peer_certificate to that returns peer X509 PEM.
648 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
649 NULL if SSL is unavailable.
651 Documentation about MARC decoding tools.
653 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
655 --- 2.0.19 2004/03/30
657 Rename CHANGELOG to NEWS to follow GNU style packing.
659 Fix bug with missing initialization of member in init_diagnostics.
660 This bug affects threaded version of GFS server.
662 --- 2.0.18 2004/03/20
664 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
667 Ensure zlib.dll is packed with Windows install.
669 --- 2.0.17 2004/03/17
671 Fix encoding of xsd:string to use text instead of CDATA.
673 Fix endless loop in CQL parser with unbalanced ".
675 Use a more compact way to store MARC-8 conversion tables.
677 --- 2.0.16 2004/03/16 Debian only
679 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
682 Update CQL parser to use new CQL 1.1 modifiers for booleans and
687 --- 2.0.15 2004/03/01
689 Another fix for decoding of XML packed records.
691 --- 2.0.14 2004/02/25
693 Fixes for Chunked encoding. White space not ignored after length spec.
695 Update NS and use default NS for SRW diagnostic elements.
697 --- 2.0.13 2004/02/23
699 Implement ZOOM_resultset_cache_reset which resets record cache.
701 Implement ZOOM_resultset_sort which sorts a result set.
703 Implement chunked HTTP transfer.
705 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
707 --- 2.0.12 2004/02/16
709 Added member 'schema' to bend_explain_rr structure so that backend
710 can specify explain record identifier. Defaults to Zeerex 2.0.
712 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
714 --- 2.0.11 2004/02/16
716 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
719 Added init command for yaz-client which sends "extra" init request.
721 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
722 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
724 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
726 Make ZOOM error code for "invalid query".
728 Fixed compilation for SSL which wasn't properly enabled for all platforms.
730 --- 2.0.10 2004/02/05
732 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
735 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
737 Added option -p <file> to make Generic Frontend Server to write PID file.
739 Added option -D to put Generic Frontend Server in background on its own.
741 Make ZOOM C recognize option "password". If unset, "pass" is used
742 (for backwards compatibility).
744 Fixed a bug in Generic Frontend Server that could make it crash if a
745 client sets characterSetNegotation bit, but didn't pass negotiation stuff
748 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
749 Must be issued before open, in order to be in effect.
751 --- 2.0.9-6 2004/01/12 Debian/Windows
753 Make the SRU server more picky WRT unknown params, etc.
755 Bug fix: ZOOM scan response didn't return displayTerm - when present.
757 New YAZ client command, options, that sets Z39.50 options.
759 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
760 options from a string of tokens (one token for each option bit).
762 Update SRW diagnostic code messages.
764 --- 2.0.9-5 2004/01/07 Debian/Windows
766 Handle user defined stylesheet for SRW/SRU.
768 --- 2.0.9-4 2004/01/06 Debian/Windows
770 Fix bug in decoding of Content-Length.
772 --- 2.0.9-3 2004/01/06 Debian/Windows
774 Fix a bug with decoding of XML packed records.
776 --- 2.0.9-2 2004/01/05 Debian only
778 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
780 Fix bug in SRW/SRU diagnostics decoding.
784 Fixed bug in Generic Frontend Server which could drop records exceeding
785 preferred message size. Reported and fixed by Irina Dijour.
787 Fixed calculation of package size for structured records in Generic
788 Frontend Server. Reported and fixed by Irina Dijour.
790 Fixed namespace for SRW/SRU diagnostics.
792 Fixed SEGV in yaz-client that occured for HTTP connection errors.
796 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
797 this version is incompatible with version 1.0 and older YAZ SRW/SRU
800 CQL changes to reflect recent changes to the specification:
801 * Documentation talks about context sets instead of index sets.
802 * Documentation talks about indexes instead of qualifiers.
803 * The CQL-to-PQF transformer's configuration file now uses
804 "index.set.name = <attributes>" instead of the old form
805 "qualifier.set.name = <attributes>". (Both forms are still
806 understood but the latter is deprecated.)
807 * CQL terms with no explicit index specified are now interpreted as
808 cql.serverChoice instead of srw.serverChoice (which of course
809 behaves exactly the same.)
813 MARC conversion can now generate ISO2709 output in another
814 character set. yaz-marcdump uses this facility if you invoke it
817 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
818 functions from there can be used from C++.
822 Frontend server now transfers memory from decoded packages to stream
825 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
826 references to show up.
828 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
829 the ZOOM Abstract API. The older names for the same options are still
830 also supported for the benefit of old applications.
832 ZOOM-C supports "implementationId" and "implementationVersion" options
833 to go along with "implementationName". These allow the user code to
834 specify identification strings to be sent to servers.
835 Add OID for the new ExtLite attribute set.
837 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
838 as requested/supplid by Ere Maijala <ere@atp.fi>
840 For generic frontend server, reverse the order of
841 "toolkit-supplied / application-supplied" strings sent as implementationId,
842 Name and Version. Also, remove the spaces around the slash. This brings
843 the GFS in line with the behaviour of ZOOM-C on the client side.
845 Add function ZOOM_scanset_display_term.
847 yaz-client shows scan displayTerm if present.
849 Utility yaz-iconv is now installed by default along with the man page
852 Extend configure check for OpenSSL to use pkg-config where available (such
855 Incorporate patch by Morten Bogeskov which allows a Unix file socket
856 server to specify uid/gid/mask for socket using the format
857 unix:[user=uid,][group=gid,][umask=mask,]file=path
858 If file= is omitted the existing format is assumed, e.g.
860 in which case the mask is 0666 (rw for everybody).
862 Major restructure of YAZ source. All source in libyaz is in src directory.
863 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
864 util (utility programs such as ASN.1 compiler, yaz-marcdump).
866 Added man page for utility yaz-marcdump (used to be called marcdump).
867 yaz-marcdump is installed by 'make install'.
869 Fixed a memory leak in Generic Frontend Server that occurred when decoding
870 of incoming package failed.
872 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
874 Change prototype of odr_perror: add const to message string.
876 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
878 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
879 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
880 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
881 DNS lookup. There should not be any compatibility problems with this
882 assuming that blocking=1 or 0 is used.
884 Fix bad reference in UNIX comstack in function cs_addrstr.
886 Fix for compilation on AIX.
888 The generic front-end server (server/seshigh.c) now supports returning
889 Init diagnostics to the client in User-information-field, in
890 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
895 Allow any CQL relation (not just all,any,exact,scr).
897 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
898 that features the same UI.
900 Implemented command update0 in YAZ client which is equivalent to
901 update but uses old of Ext Update ASN.1.
903 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
904 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
905 Previously no OID was used for this info.
907 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
908 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
909 returns 'malformed search term' otherwise.
911 SortResponse member resultCount now set to NULL in sort handler of
914 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
917 Add three new utility functions for translating OIDs between various
918 formats -- symbolic name such as "Usmarc", minus-1-terminated int
919 arrays and dotted strings such as "1.2.840.10003.9.5.1":
920 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
921 char *oid_to_dotstring(const int *oid, char *oidbuf);
922 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
924 Reverted modifications for ES Update definition for z_IU0Update
925 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
926 is back to YAZ 2.0.2.
928 String value attributes for CCL parser.
930 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
931 which their FirstSearch server returns in Init responses, sometimes
932 carrying useful diagnostic information when Init fails. This has the
933 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
934 "z39.50/oclcui.asn", where its definition is somewhat different from
935 what OCLC document on their web-site, as required to interoperate with
938 Support for anonymous authentication in yaz-client. Use the command
941 * Fix the OID of the Index Data-local "admin" Extended Service from
942 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
943 the 1000, which indicates a locally-defined OID, was a mistake.
947 Fix CCL directive @case handling so that it affects string match for
948 both CCL keywords and qualifiers.
950 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
951 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
952 Decoder has been updated with ASN.1 changes as listed in
953 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
954 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
955 z_IUUpdate, remains unchanged.
957 ZOOM_record_get may now return a record in a specific character set.
958 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
959 "from" is the character set of record as returned by target. "to" is
960 the character set to be returned. If omitted, "to" is UTF-8.
962 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
964 New ODR utility, odr_getelement, which returns name of element for
965 which encoding/decoding failed.
967 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
968 in cases where a required element was omitted.
970 Bug fix: some MARC8 sequences were not converted.
972 New ZOOM option "step" which specifies number of records to be
973 retrieved in one chunk. Used in conjunction with "start" and "count".
975 SRW support for yaz-client. Use scheme http: to use it, e.g.
978 yaz-client no longer does (un)intelligent character set conversions
979 by default. Can be enabled with charset and marc_charset commands.
981 xmalloc trace fix for 64-bit systems such as DEC alpha.
983 Solaris 2.6 compile fix.
985 New function, cql_strerror() translates SRW error codes, as returned
986 by cql_transform_error(), into human-readable English strings. Used
987 in yaz-client diagnostics when appropriate.
989 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
990 converts it into a type-1 query which is sent to the server. This
991 makes CQL available for use with all Z-servers, as opposed to the tiny
992 minority that can handle CQL queries themselves.
996 New Debian package layout similar to the Redhat Package layout.
998 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
999 and search result respectively.
1001 --- 2.0.1 2003/04/25
1003 Redhat package is now several packages: libyaz (runtime libraries),
1004 libyaz-devel (development and documentation, and yaz (utility programs).
1005 Package spec file by Morten Bøgeskov.
1007 New member 'schema' in struct bend_fetch_rr which the name of requested
1008 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1009 handler MAY set this to reflect the schema of the returned record.
1011 New member 'display_term' in struct scan_entry. GFS now sets member entries
1012 and allocates scan entries to be filled by user scan handler. In previous
1013 version, entries member was allocated by the scan handler. That still works,
1014 but the GFS will ignore member display_term - assuming it was NOT set by
1015 the handler. The fact that the GFS now allocates the entries both allows
1016 for new members and makes a scan handler easier to write.
1018 Fix CQL lex buffer overflow.
1020 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1021 SRU default recordPacking is string.
1023 SRU protocol support for frontend server.
1025 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1027 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1029 Added scan for the ZOOM shell (zoomsh).
1033 * String Identifers for Schemas (Amendment 5).
1034 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1035 Old definition for schema
1036 Odr_oid *schema; /* OPT */
1041 Z_InternationalString *uri;
1042 #define Z_Schema_oid 1
1043 #define Z_Schema_uri 2
1046 * resultCount parameter to Sort Response (Amendment 1).
1047 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1049 Support for SRW 1.0 over HTTP. This is an optional feature and
1050 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1053 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1054 on the same port. SRW SearchRetrieveRequests are mapped
1055 to bend_init,bend_search,bend_fetch,bend_close.
1057 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1059 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1060 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1062 ZOOM connections are SRW based if schem http is used for hostname
1063 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1064 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1066 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1067 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1068 distance=n, order=true/false, relation=le, prox unit=word. If
1069 n is omitted, distance 1 is used.
1071 Fixed problem with C compiler include path in wrong order.
1073 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1074 on Solaris. Patch from Ko van der Sloot.
1076 New MARC decode API. All new functions operate on a yaz_marc_t
1077 handle. The most important new functions are: yaz_marc_create,
1078 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1079 decode and destroy respectively. Decoder can produce formats
1080 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1081 include/yaz/marcdisp.h.
1083 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1084 to UTF-8, UCS-32, wchar_t or Latin-1.
1086 * Prototypes for yaz_iconv_-functions moved to separate header
1087 include/yaz/yaz-iconv.h.
1089 Make a few private functions 'static' in unix.c. This prevents
1090 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1092 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1093 are set when Init Response is received.
1095 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1096 but returns diagnostic set as well.
1098 New function yaz_strerror which is a portable wrapper for
1099 strerror/strerror_r/GetLastMessage.
1101 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1102 is returned for MARC. If type is "oai", then OAI MARC is returned.
1104 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1107 --- 1.9.2 2002/11/26
1109 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1111 Fix bad race conditions on SIGTERM and terminate gracefully in
1114 Move retrieval (data1) module to Zebra since nobody seems to be
1117 Add GRS-1 render for ZOOM using same format as yaz-client.
1119 --- 1.9.1 2002/10/05
1121 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1123 Fix broken ESpec handling in data1 module.
1125 SGML reader parses comments and makes them part of the data1 tree.
1127 Added several type casts so that YAZ compiles as C++ code.
1129 ZOOM didn't handle PDU encoding failures properly.
1131 Added more Bib-1 diagnostics (approved extensions).
1133 GNU configure: better check for iconv.
1135 More portable use of accept, getpeername. Check for socklen_t. Use
1136 int/size_t if socklen_t is not defined.
1140 PQF parser rejects bad queries - including those with extra
1141 characters in them. PQF parser used to silently ignore that.
1142 Cleaner API for PQF added, which allows you to get detailed
1143 error information for bad queries (see yaz/pquery.h).
1145 Fixed bug in ZOOM_record_get for type "database".
1147 Implemented mini iconv library supporting conversions between
1148 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1150 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1152 --- 1.8.9 2002/08/20
1154 Fixed ZOOM C record cache so that preferredRecordSyntax and
1155 elementSetName is used to check for already fetched records.
1157 --- 1.8.8 2002/08/02
1159 Added three members in bend_initrequest structure to facilitate
1160 character set negotiation.
1162 Fixed a bug in frontend server that could cause indefinite
1163 loops under rare conditions.
1165 Revised character set utilities (charneg.h) so that encoding
1166 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1168 For PQF, directive @term <type> sets term type for Scan/Search.
1169 Here <type> is general, string, numeric, null. The term type
1170 is inherited - just like @attr.
1172 New call odr_set_charset that sets character set conversion for
1173 international-strings on a ODR stream. Prototype is:
1174 int odr_set_charset(ODR o, const char *to, const char *from);
1175 The InternationalString is still represented as C string in YAZ
1176 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1177 won't). On the protocol level, you can use any encoding.
1179 Support for UNIX sockets in ZOOM.
1181 Solaris recv sometimes returns errno == ENOENT. It is treated as
1182 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1184 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1185 both client and server. Code by Morten Bøgeskov.
1187 --- 1.8.7 2002/05/22
1189 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1190 that they can be used directly from Visual Basic. You must recompile
1191 your windows APP if you're using ZOOM.
1193 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1194 Commands "lang" and "charset" sets language and character set respectively.
1195 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1196 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1198 Attributes from multiple CCL fields may be OR'ed rather than merged
1199 using directive "@field or". Fields are still merged by default -
1200 equivalent to "@field merge".
1202 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1205 Fixed bug in zget for parameter ExtendedServicesResponse.
1209 --- 1.8.6 2002/03/25
1211 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1213 Client displays USR.1:SearchResult-1 (hits per term).
1215 Additional Search Info for search in Generic Frontend Server.
1217 Fixed CCL parsing of "field=s".
1219 WIN32 installer - using the excellent NSIS software from nullsoft.
1221 Fixed CCL parsing of "field = - <number>".
1223 Added function yaz_marc_decode that decodes MARC for line mode
1224 display or XML (similar to that used by JZKit).
1226 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1227 Z39.50. But ISO/ILL was, however.
1229 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1230 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1232 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1233 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1235 --- 1.8.5 2002/02/03
1237 New YAZ client features: Command completion and new commands:
1238 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1239 Code provided by Jacob Poulsen.
1241 New call oid_trav, that visits all registered OIDs via callback.
1243 Function ZOOM_record_get now returns const char pointer rather than
1244 void pointer. It saves a lot of type casts.
1246 For YAZ client, command "auth" now allows you to set authentication
1247 in IdPass style. It is enabled when three tokens are given - order
1248 is user, group and password.
1250 Fix memory leaks in MARC record handling for ZOOM.
1252 New option for YAZ client, -k <kilobytes> that sets
1253 maximum record size. Similar to -k option for generic frontend
1254 server and yaz-ztest.
1256 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1258 Prefix query parser reports "fail" when bad attribute set is given.
1260 Fix in MARC decoder. Proximity logging. Fix for attribute set
1261 in scan handler for server. Patches by Shigeru Ishida.
1263 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1266 Configure option --with-openssl=<dir> now works when a directory is
1267 specified. Patch provided by Morten Bøgeskov.
1269 New option for YAZ client, -u <auth>, that sets authentication.
1271 ZOOM fix: error information was sometimes "missing", since error
1272 was cleared/reset too when it shouldn't.
1274 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1276 --- 1.8.4 2002/01/04
1278 Scan for ZOOM API. New object ZOOM_scanset. New functions
1279 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1280 ZOOM_scanset_destroy.
1282 New ZOOM function, ZOOM_connection_last_event, that returns type
1283 of last event (such as "receive data", "send data", "apdu received",
1286 New ZOOM option, schema, that specifies schema for retrieval.
1288 New CCL feature. Qualifiers can be aliases for one or more
1289 other qualifiers (if more than one is given, OR is used).
1291 ZOOM uses named result sets if target supports it.
1293 Two new YAZ client commands: . (dot, which sources a script of YAZ
1294 client commands), and ! (to execute shell command.). Implemented
1297 Working on Debian packages.
1299 --- 1.8.3 2001/11/19
1301 YAZ client enables named result sets only if target supports it.
1303 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1305 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1306 with key="host" to get same result.
1308 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1309 Function Z3950_resultset_record(s) returns references to records
1310 "owned" by resultset. To become owner use Z3950_record_clone.
1312 Function z_ext_record handles Extended Services. Thanks to
1315 --- 1.8.2 2001/11/12
1317 CCL Parser fix: ignore token comma when dealing with and-lists.
1319 Documentation updates for COMSTACK.
1321 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1322 Changed prototype Z3950_records. For some functions, int parameters
1323 were changed to size_t.
1325 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1328 New MARC decode/display function, marc_display_exl, which properly rejects
1329 non-ISO2709 records. YAZ client uses it.
1331 --- 1.8.1 2001/10/29
1333 Fix bug: local attribute set wasn't set correctly in PQF strings.
1337 * Old Z39.50 codecs no longer supported.
1339 Added ZOOM C binding. See http://zoom.z3950.org/
1341 Renamed states for COMSTACKs to avoid confusion with events.
1343 Implemented cs_look and proper cs_rcvconnect.
1345 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1347 Configure detects POSIX threads on OpenBSD.
1349 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1350 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1352 When error is returned from present handler, non-surrogate diagnostic
1353 is returned in present response (and fetch handler is no longer called).
1355 * Minor adjustments to pquery parser (PQF). Token characters may be
1356 escaped by using backslash (C-style).
1358 PQF parser allows string attribute values to be specified. For @attr,
1359 non-numeric characters after the equal-sign are treated as strings
1360 (e.g. @attr 9=title).
1362 CCL trunction character may be defined (@truncation in file)
1364 * function zget_ExtendedServicesRequest sets waitAction to
1365 waitIfPossible (was wait).
1367 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1370 CCL operator names may be set in field definition files (CCL_bibset).
1371 See ccl/bib1 for an example.
1373 Fixes in ASN.1 compiler for C++ compatibility.
1375 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1376 and "op_or" to avoid conflict with C++.
1378 Fixed problem with GNU readline detection on Redhat 7.0.
1380 Added step-size for Scan backend handler.
1382 Fixed bug that made the frontend server crash when no attribute
1383 set was specified for scan.
1385 Front-end server automatically switches to original working directory
1386 when installed as an NT service. Previously -w had to be specified to
1389 Added extended attributes for retrieval module (data1), so that data1
1390 records carry d1_readXML/SGML attributes. d1_read also supports
1391 null-data rules ( <tag/>)
1393 On UNIX when POSIX threads are available, a separate library libyazthread
1394 is created. Programmers should link with that library and the yaz library
1395 when using threads. The reason for the split was that some applications
1396 on Linux, such as Apache, doesn't work well when using shared objects that
1399 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1400 (or any frontend server) in SSL mode by specifying ssl: followed by
1401 address. Only tested on UNIX.
1403 Added feature for CCL module. Virtual structure s=al or s=ol generates
1404 and-list and or-list respectively instead of phrase search.
1408 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1409 log_mask_str. This was done to avoid name conflicts with other libraries
1410 (such as other PHP extensions).
1412 Added raw OID member for preferred record syntax (request_format_raw)
1413 and returned record syntax (output_format_raw) for backend fetch method.
1415 Config file yaz-config now accepts options so that it returns specific
1416 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1418 Shared library support for UNIX using GNU libtool.
1420 * Modified backend interface. Request/Response struct's replaced by
1421 one read/write C struct. For example bend_fetchrequest and
1422 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1423 Every handler - even search has to be registered in bend_init
1424 handler. This means that the YAZ library no longer refers to
1425 external functions and it makes it possible to make the whole
1426 thing a single DLL/SO.
1428 Added Segment handler for backend server.
1430 Added Zmbol/Zebra administrative functions to YAZ client.
1432 Threaded frontend server on UNIX (when POSIX Threads are available).
1433 Starting the server with option -T enables multi-threading.
1437 Added configure option --enable-comp/disable-comp to control use
1438 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1439 located in sub directory asn.
1441 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1442 in ${exec_prefix}/bin along with the other programs yaz-client and
1445 GNU automake used to maintain makefiles.
1447 Added several OID's.
1449 Changed retrieval module so that we can load records with no abstract
1450 syntax defined. Tagpaths in these records are fully composed of string
1453 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1457 On UNIX, the generated makefile now supports a proper 'make install'.
1458 The prefix can be set via GNU configure to set the install location
1459 (default is /usr/local).
1461 * YAZ programs client and ztest were renamed to yaz-client and
1462 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1463 locations, such as /usr/bin,/usr/local/bin,etc.
1465 * YAZ Header files were moved from include to include/yaz. YAZ Header
1466 files are referred to as include <yaz/log.h> rather than <log.h>.
1467 The YAZ include path (-I ..) is therefore the same as before. Programmers
1468 should update their #include statements or use -Ipath/include/yaz
1469 instead. The main motivation for doing this change is that YAZ header files
1470 can be installed in "standard" locations /usr/include,/usr/local/include
1471 without introducing conflicts, since ALL YAZ header files are stored
1472 in subdirectory yaz (under /usr/include for example).
1474 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1475 rather than project/workspace files. We switched because project files
1476 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1479 Changed name of logging function, logf, to yaz_log, to prevent name
1480 clash with some math-log functions. The YAZ header log.h defines logf
1481 to yaz_log (#define) so there should be no incompatibilities by this
1484 Added bend_start/bend_stop handlers for server. These handler are
1485 called on start/stop of server. For windows they are called whenever
1486 a service is started/stopped.
1488 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1489 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1490 in util/yc.tcl. The auto-generated C code structures are, in a few
1491 cases, incompatible with the old decoders. There are differences in the
1492 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1493 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1494 The preprocessor variable ASN_COMPILED is defined when the compiled
1495 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1496 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1497 wish to use the old encoders/decoders you can specify --disable-yc
1500 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1501 version so that it supports both new - and old version of DB Update
1503 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1504 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1505 change. The name parameter can be set to 0 in which no name is specified
1506 for the construction. The macros odr_implicit and odr_explicit sets name
1507 parameter to zero for the construction involved. New macros
1508 odr_implicit_tag and odr_explicit_tag are similar to the others,
1509 except that a name parameter is added. For programmers' that don't use
1510 ODR they probably only need to change the call to z_APDU and z_External.
1512 Added access control facility by interfacing the TCP wrapper library.
1513 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1514 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1515 name of the daemon and enables the access control as specified in
1516 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1518 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1519 den Dool <H.M.vdnDool@kub.nl>.
1521 Added reference ID parameter to most functions in server API - refer
1522 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1524 Changed name of ccl library to libccl.a (was ccl.a).
1526 Fixed bug in decoder for Explain (Category TargetInfo).
1528 Added support for GNU readline in client. Thanks to Jacob Poulsen
1529 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1531 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1532 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1533 IMPLEMENTATION! This change was made to the development version before
1534 the ZIG decided to retract the amendment. If any users MUST be
1535 compatible with the original Update definition, PLEASE CONTACT US, and
1536 we will include a separate definition corresponding to the old Update
1537 ES. Note that because of the change to the ASN.1 of the
1538 TaskPackageRecordStructure we cannot define a single structure that
1539 will support both versions.
1541 * Added const modifier to buffer parameter for some ODR/BER encoding
1542 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1543 completeWAIS, odr_dumpBER.
1545 Fixed bug in client.c which caused a crash when a scanResponse didn't
1546 contain positionOfTerm.
1548 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1549 * will cause an error in a client if a non-YAZ target sends both a
1550 * list of Scan entries and non-surrogate diagnostics.
1552 Retrieval module enhancements. Tag sets may be typed in the reference
1553 to it. From the .abs-file the "tagset" directive takes a third optional
1554 integer type for the tag set referenced. From a .tag-file the "include"
1555 directive takes a third optional type as well. The old "type" directive
1556 in the tag set itself is still recognized but acts as the default type
1559 Backend interface change. Individual Scan terms returned from bend_scan
1560 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1561 in include/backend.h.
1563 Retrieval module enhancements. Multiple tag sets and attribute sets may
1564 be specified in abstract syntax specs. Revised the error/warning for
1565 logging messages reported by the retrieval module when reading the
1568 Object Identifier system (oid_..) changed. The API is backwards
1569 compatible but the oid-routines now allocates new OID's when needed.
1570 Raw OID's may be specified in oid_getvalbyname.
1572 YAZ now uses GNU configure to generate Makefile(s).
1574 * Minor changes in some of the member names of DeleteResultSetRequest and
1575 DeleteResultSetResponse. See include/proto.h.
1577 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1578 and added member 'languages' in TargetInfo (which was missing).
1580 Changed the way attribute sets are handled in the retrieval
1581 module. These are now cached, just like the abstract syntaxes
1584 Changed YAZ so that it links with compiled ASN.1.
1586 Added Explain-schema definitions and mapping routines. The following
1587 Explain categories have been implemented: AttributeDetails,
1588 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1590 Fixed minor bug in Windows version of Server Library.
1592 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1594 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1596 Added EXTERNAL: UNIverse Resource Report (non-standard).
1598 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1599 ENUMERATED and SET OF.
1601 * Added 'const' to some of the char pointer arguments for the
1602 functions, data1_read_node, data1_getelementbytagname,
1603 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1606 Fixed bug in data1_insert_taggeddata - the last_child member of
1607 parent wasn't initialised.
1609 * Changed data1_read_record and data1_read_node so that the supplied
1610 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1611 doesn't refer to any parts of the "SGML"-buffer.
1613 Fixed bug in server library (Windows version of statserv_remove).
1615 * Changed code so that it compiles as C++. The type definition
1616 of Odr_fun which is a member of Odr_arm was changed. The result is,
1617 that an explicit typecast is needed for the fun pointer when
1618 using Odr_arm - as in:
1619 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1621 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1623 Implemented the new structured date and time definition as approved
1624 by the ZIG. Added schemaId element to the specificTag in Espec-1
1625 (also approved at the last ZIG). Thanks to RVDM.
1627 Added some Object identifiers (RVDM).
1629 Changed the Update Extended Service (RVDM).
1631 Added command "refid" to client which specifies referenceId for
1632 the following requests.
1634 Implemented extended service handling for server. See ztest.c
1635 for an example as well as backend.h. New handlers are registerd
1636 in the Init handler.
1638 * Changed interface for sort in server.
1640 Added new members to statserv_options_block. It allows a server
1641 to read options from another source than just the command line. Thanks
1642 to Charles Woodfield.
1644 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1645 renamed to zboolean. Some C++ compilers complained about the name.
1647 Minor changes to gils.abs. Added index 's' (sort) on title
1648 and date/time-last-modified.
1650 --- 1.4pl2 1998/1/30
1652 Fixed bug in server library regarding inetd mode (-i). This bug
1653 was introduced by release 1.4.
1655 --- 1.4pl1 1998/1/29
1657 Added sort facility in client and backend server interface.
1659 Fixed problem with dependencies in Makefile(s).
1661 Fixed bugs for encoders/decoders of extended services and
1664 Implemented sub-tree feature for schemas. Sub-trees are
1665 referenced in *.abs-files. See explain.abs for an example
1666 of the use of this feature.
1668 Modified bib1.att; local attributes for ANY didn't include
1669 ANY itself (only affects use of the retrieval module).
1671 Fixed bug in plain SGML reader in function data1_read_node:
1672 tags with prefix "var" was incorrectly interpreted as variants.
1674 Added feature "sub-schemas" to enable references to - and definitions
1675 of - group of elements.
1677 * Removed member parent from type data1_element (in data1.h).
1679 Implemented function odr_nullval() that returns the value of
1682 * Removed member num_children from data1_node (in data1.h).
1684 Made NT service interface part of the server library. The
1685 function statserv_main uses the NT service when required and
1686 calls the statserv_start / statserv_close routines.
1688 Routine zget_SearchRequest and zget_PresentRequest fills
1689 resultSetName/Id member with "default" instead of "Default".
1691 Fixed memory leak in server. Request queue member wasn't freed.
1693 Fixed nmem_exit so that memory is freed.
1697 Revised the CCL parser utility to be thread safe.
1699 Added function, oid_ent_to_oid, to replace the function
1700 oid_getoidbyent, which is not thread safe.
1702 * Added nmem_init and nmem_exit to initialize and release
1703 NMEM resources. Function nmem_init should be called once in the
1704 initial thread before NMEM/ODR is used. statserv.c and client.c
1705 have been changed accordingly. The change was necessary to make
1706 NMEM thread safe. The NMEM memory pool is shared amongst threads
1707 in a process. Unix-based applications will still work fine without
1710 Added NT Services interface for the the Z39.50 (statserv) Server.
1711 Refer to the ztest.c source on the usage.
1713 Windows 95/NT port using MSVC5.0. Project files are included in the
1716 * Defined new 'global' handle for the retrieval (data1) system. The
1717 new handled, data1_handle, describes the state of the data1 system.
1718 This handle is passed as first argument to virtually all
1719 data1 related routines. The functions data1_create and data1_destroy
1720 creates and destroys a data1 handle respectively.
1722 Added ODR encode stream member to all backend request structures
1723 init, search, scan etc. This stream should be used to allocate all
1724 memory used for the response when thread safe operation is needed.
1726 Changed the comstack utility, cs_addstr, to be thread safe. The
1727 returned hostname string returned by the function is now part the
1730 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1731 function. The cs_straddr takes a COMSTACK handle as argument, so this
1732 function must be used after cs_create and before bind/connect.
1733 This function is thread safe.
1735 Moved test server to 'ztest' directory - generic server code still
1736 in 'server' directory.
1738 Made prefix query (pquery.c) utility thread safe.
1740 Added new function modifier YAZ_EXPORT to 'export' public DLL
1741 functions when using windows (see include/yconfig.h).
1743 Added definitions to the OID database (util/oid.c) (RVDM).
1745 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1747 Added call to ccl_rpn_delete in client program.
1749 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1750 release of RPN structure.
1752 Added support for C++, headers uses extern "C" for public definitions.
1753 With input from RVDM.
1755 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1756 Thanks to Ronald van der Meer (RVDM).
1758 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1760 Added support for private extensions to the OID database
1761 (oid_setprivateoids()). Thanks to RVDM.
1763 Added optional, physical ANY (key replication)
1765 Fixed null-reference problem in GRS-1 output filter.
1767 Proximity operator added to Prefix Query Format (PQF).
1769 In test client command "base" accepts multiple databases.
1771 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1775 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1777 Smallish bug-fixes in the new encoders/decoders (explain).
1779 Bug fixed in DeleteRequest.
1781 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1783 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1785 Added SOIF syntax (using private OID for now) to retrieval module and client.
1787 Added Update extended service.
1789 Added SearchResult-1 additional info structure.
1791 Added optional CCL (ISO8777) interpreter as separate module. Available
1794 --- 1.2 1996/6/10 (1st anniversary release)
1796 Added Summary record syntax. Lightly tested.
1798 Added OPAC record syntax. Untested.
1800 Added ResourceReport service encoders/decoders. Untested.
1802 Fixed bug in z_Unit - wrong tagging on unitSystem.
1804 Fixed bug in the DiagRecs decoder.
1806 Added options for max PDU size and session timeout to frontend-server.
1808 Added documentation of query-language parsers and other supporting utilities.
1810 [frontend-server] Added Attribute set to the bend_scanrequest API.
1812 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1813 surrogate diagnostics were generated.
1815 [retrieval] Allow multiple local values for attribute.
1817 [retrieval] Allow multiple attributes per element in .abs files. index type.
1819 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1821 --- 1.1pl2 1996/4/10
1823 Minor changes, mostly specific to Zebra's requirements (retrieval)
1827 Repaired bug in frontend server when running multiple listening
1828 endpoints in dynamic mode.
1830 z_External() now won't break if a known, ASN.1 value comes encapsulated
1831 in an octet-string. The value will pass through unmodified in an Odr_oct.
1833 Added a bit of code to the demo client to decode & display
1834 ASN.1-structured records represented in the octet-aligned branch of
1835 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1837 Added z_ext_getentbyref() to the ASN module. Doc updated.
1839 * Completed the SCAN definition in the ASN module. This may break SCAN
1840 code based on older YAZ-versions at compile-time. The fix is easy -
1843 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1844 under the SCAN definition. Remember to initialize this, server-people.
1846 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1847 that this does not extend to ODR and ASN.
1849 Comstack allows insertion of established socket (primarily for
1850 inetd-operation of servers). Doc updated.
1852 Front-end server can now start from the inetd in TCP mode. Doc
1855 --- 1.0pl4 1996/1/24
1859 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1860 the rank and record number.
1862 Adjustments to the frontend server.
1864 Fixed diagnostic BER dumper. It ignored the file argument.
1868 Various changes to retrieval module.
1870 Changed the union discriminators of the protocol files from enums to
1871 ints paired with #defines.
1873 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1876 *Changed operator in the RPN structure to 'roperator', again to avoid a
1879 Fixed problems in Explain decoders/encoders.
1881 --- 1.0pl2 1995/12/6
1883 Memory bug in log module fixed.
1885 --- 1.0pl1 1995/12/5
1887 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1889 Bug in Explain DatabaseInfo module fixed.
1891 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1895 The shift to v1.0 signals that we now consider the *core* functionality
1896 of YAZ reasonably stable (the core being more or less equivalent to
1897 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1898 tested (Explain not at all - though that will happen soonish).
1900 Minor changes to code to support Windows port.
1902 Various minor changes after we're getting to use GRS-1 & co. more.
1904 Added Espec-1 format.
1906 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1907 of the protocol and it cannot be selected when encoding (maps into 'string'
1908 when decoding). Needed to talk to some servers.
1910 Demo client can request simple element set names.
1912 Added Diagnostic Format encoders/decoders.
1914 Added simple Close handling to frontend server (no hooks for resource
1915 reporting yet), and demonstration client.
1917 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1919 --- 1.0b3 1995/08/24
1921 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1922 handled incorrectly when records were requested in the searchResponse. This
1923 will only affect you if you use the frontend-server.
1925 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1926 Test-client will ask for and print GRS1. Ztest will return dummy records
1929 Added Explain encoders/decoders to the service-level API. Untested.
1931 Added Extended Services: Item Order encoders and decoders to the Service-
1932 level API. Untested. We could use a recent copy of the pertinent bits
1933 of the ILL protocol to add those bits.
1935 Added diagnostic format 1 encoders/decoders to the service-level API.
1938 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1939 odr_cons.c, which causes a more correct output.
1941 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1942 was always set to 0 when no records were requested in the searchRequest.
1944 * Added better external-handling. This shouldn't harm old code that
1945 *encodes* externals. It can break code that looks for a
1946 'single-ASN1-type' representation, since those types that are known
1947 are now decoded immediately. Look at the SUTRS sample code in
1948 seshigh.c and client.c. Documentation updated.
1950 Handling of structured records in bend_fetchresponse. Length -1 marks
1951 structured record, type is deduced from format field.
1953 --- 1.0b2 1995/06/27
1954 Fairly quick maintenance release to add SUTRS support.
1956 Fixed handling of SUTRS records in the demonstration client.
1958 * Added format field to the bend_fetchrequest and bend_fetchresponce
1959 structures of the backend API (frontend server). When the record is
1960 returned, the value of the format field is mapped to an OID. The
1961 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1962 of the record. The special value VAL_NONE in the bend_request means
1963 that no specific format was requested by the client. Documentation
1964 updated accordingly. Test server (ztest) will return a fixed dummy
1965 SUTRS record if your client requests SUTRS.
1967 Documentation updated accordingly.
1969 You can now set external libraries and RANLIB support in the top-level
1973 First public release.
