1 Fixed bug #775: char conversion does not handle Alternative UTF-8
4 Implemented function yaz_marc_read_line which parses MARC line format
5 records. There is a wealth of formats out there. So far, this function
6 reads line records produced by yaz_marc_write_line.
8 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
9 more generic and easier to remember(!) options: -i format and -o format
10 which specifies input format and output format respectively - where
11 format is one of "marc", "marcxml", "line", "marcxchange".
13 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
14 does not print anything except warnings for records.
16 For yaz-marcdump, added support for MARC split into files (-s) with a given
19 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
20 spec, at http://www.loc.gov/standards/sru/record-update/
21 This has changed the binary layout of the following structs:
22 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
23 bend_update_rr . Patch by Ko van der Sloot.
25 Added GFS utility function bend_assoc_is_alive which returns 1 if
26 association is still alive (client is connected); 0 otherwise (client
27 closed connection). This allows busy servers to stop working for
30 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
31 been a separate piece of software. This version of ziffy has been modified
32 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
34 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
36 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
37 Client code may now interrogate options such as "init_opt_sort" to
38 find out whether the server claims to support various options.
42 Added utilities yaz_{set,get}_esn to set/get element set name from
45 Removed the build of libyazthread.la. The libyaz.so is the threaded version
46 of YAZ and has been so since YAZ 2.1.10.
48 Implemented ZOOM_record_error which returns error information for
49 record (surrogate diagnostic).
53 Updates for SRU Update by Ko van der Sloot:
54 1. Changed name from "operation" to "action"
55 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
56 versions in the code, marked as 'backward compatible'.
57 3. Added diagnostics for SRU Update.
59 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
61 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
63 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
65 For GFS, fixed problem with SRU diagnostic 'First record position out of
66 range' being issued for 0 hits.
68 zoomtst10 part of Windows Build.
72 Implemented yaz_filepath_comp which splits a path into file path
73 components (required by Zebra 2.0.3+).
75 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
76 BSD inspired license until now so this should not have any real impact on
77 anybody. See http://www.opensource.org/licenses/bsd-license.php
79 Fixed bug #687: Missing log lines.
81 Fixed bug #678: CQL to PQF translation does not preserve double-quote
84 Fixed bug #689: SRU diagnostics to be added.
86 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
87 whether a connection is idle (no more work do do).
91 Change type of optval from long to int for invocation of setsockopt with
92 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
94 Added support for specifying the max log file size for the Generic
95 Frontend Server. The size is given with option -r.
99 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
101 --- 2.1.30 2006/09/17
103 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
106 Fixed bug in Generic Frontend Server that could cause a server to stop
107 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
109 For the generic frontend server, the maximum record size is used as maximum
110 size of incoming packages (SRU + Z39.50). The value until was previously
111 only used in Z39.50 Init negotiation and, later, in a session controlled
112 sizes of records returned. This is controlled using -k option. It can be
113 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
115 --- 2.1.28 2006/09/04
117 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
120 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
122 New option for yaz-marcdump -lpos=value which allows setting a portion
123 of MARC header to a certain value.
125 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
127 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
128 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
130 --- 2.1.26 2006/08/15
132 Fixed problem with SRU mode type (soap, get, post) for yaz-client
135 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
137 --- 2.1.24 2006/08/08
139 Fixed MARC ISO2709 encoding routines to deal with character set
142 Minor changes to GFS logging. Database included in search request log
145 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
146 cached/multiple records.
148 Shared libraries are built by default on Unix+configure.
150 Changed cql2pqf transformation to use a different evaluation order. The
151 new order is: always, relation, structure, position, truncation, index
152 and relationModifier. Old order was: always, relation, relationModifier,
153 structure, index, position, truncation. Note that the the latter ones
154 override former ones for identical attributes.. The new scheme means that
155 it is possible to override any existing attribute with a relationModifier.
156 And also that it is possible to override everything for the index rule
157 (except the ones listed in relationModifier). No order is perfect but this
158 one, we believe, covers more real cases.. The "always" should have been
159 called "default", since the attributes there can be overridden with all
162 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
163 compilation phase, but also for yaz-config --cflags output. This allows
164 us to have public headers with Libxml2 stuff in them . It should also,
165 eventually, make Libxml2 checks redundant in packages using YAZ, such
168 --- 2.1.22 2006/06/15
170 Changed SRU update structure bend_update_rr so that SRU diagnostics are
171 stored in uri, message and details.. Previously diagnostics were stored
172 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
173 compatibility.. but he's probably the only one affected, so.
175 Added support for CCL, compiled on the client side, in ZOOM-C. This
176 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
177 input; the resulting query objects can be used for for searching with
178 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
180 YAZ' configure searches for OpenSSL by default.
182 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
183 SL_CTX_use_certificate_file. See
184 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
185 for more info. Thanks to Ko van der Sloot.
187 --- 2.1.20 2006/06/02
189 Bug #600: SRU GET, POST support for yaz-client. Introduced
190 command 'sru' which selects method SOAP/GET/POST.
192 Allow missingValueAction to be specified for the sortspec string -
193 function yaz_sort_spec. By default, the missing value action is null.
194 Use ! to specify "abort". Use = followed by stringvalue to specify default
197 Ensured that Present-handler (if defined) is called in GFS before any call to
198 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
199 searchRetrieve requests.
201 Documentation for YAZ is now based on the Docbook XML/XSLT using
202 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
203 is no longer depending on jade/openjade or docbook-to-man scripts.
204 PDF is no longer part of the distribution - but can optionally be
205 made using DSSSL/jadetex or FOP.
207 Added retrieval handling support in Generic Frontend Server to support
208 conversion between MARC/XML as well as XSLTtransforms. See
209 etc/yazgfs.xml for an example.
211 Added Authentication support to Generic Frontend Server in SRU
212 mode. Authentication using HTTP Basic is supported, as is the use
213 of 'x-username' and 'x-password' parameters in the request itself.
215 Added support for a new character set MARC8s identical to MARC8 except
216 that it converts combined characters to single Unicode characters in the
217 Latin-1 range (when possible).
219 --- 2.1.18 2006/04/24
221 ASN.1 compiler 0.4: generates brief Doxygen file header for
222 generated .h/.c files.
224 Utility yaz_iconv now supports conversion to MARC-8.
226 New facilities for the MARC module. The reading - and writing of
227 content are separate methods for the yaz_marc_t handle. The following
228 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
229 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
230 format). Write functions have prefix yaz_marc_write_.. The existing
231 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
232 available. Removed support for OAI-MARC and simplexml (not the
233 simplexml from PHP5).
235 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
236 to be returned for this connection.
238 --- 2.1.16 2006/03/31
240 Allow multiple languages and charsets to be specified with
241 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
242 negcharset iso-8859-1,utf-8
244 Translation of proximity nodes from CQL into PQF now works.
246 Moved to automake 1.8, 1.9.
248 Added function yaz_log_set_handler which allows a log handler to be
249 installed. This handler will be called for all log messages. Output
250 to file is also produced; but that can be disabled by passing NULL
251 fname to yaz_log_init_file.
253 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
255 For SRW (including GFS), accept application/soap+xml as content-type
258 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
259 produces NO stylesheet reference even if a default stylesheet is specified
262 --- 2.1.14 2006/03/14
264 Updated Windows package to include yazd.dll + yazd.lib for the
265 Development component.
267 If the environment variable YAZ_LOG is set, then it is used as a
268 string indicating the default level of logging to use if not
269 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
270 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
271 used as before. So, for example, to omit warnings from YAZ logging,
274 cql_transform() now map structure and other attributes before indexes,
275 so that index-specific structures and other attributes can override
276 defaults. So now a combination of mapping specifications such as:
278 index.dc.date = 1=date-modified 4=5
279 does the right thing.
281 cql_transform() now also respects the "always" mapping specification,
282 which establishes an initial set of attributes to be used for all
283 terms except where overridden by more specific attributes associated
284 with the index, relation or modifier.
286 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
287 which mode to use; one of "post", "get" or "soap" (SRW, default).
289 Fixes for yaz_iconv routines: changed trie-based character set conversions
290 to use only non-negative values for bit fields due to Sun's C compiler not
291 supporting negative values.
293 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
294 sequences where not read correctly. Fix by Rustam Usmanov.
296 Updated win/makefile to use options, settings which makes things
297 compile with VS C 2005.
299 --- 2.1.12 2006/02/01
301 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
303 In ZOOM socket code, use select instead of poll on MacOSX.
305 ZOOM-C now support client-side compilation of CQL into RPN that is
306 sent to the server, enabling CQL to be used against all Z39.50
307 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
308 ZOOM_query object, and submit it using ZOOM_connection_search().
309 The CQL-to-RPN translation uses a configuration file, the name of
310 which must be specified in the Connection's "cqlfile" option.
312 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
313 function, which takes as its start-term parameter a ZOOM_query object
314 (which may have had either CQL or RPN set into it).
317 --- 2.1.10 2005/11/29
319 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
320 GFS to support this as well. Backend handler, bend_srw_update, does the
321 update work. Code contributed by Ko van der Sloot.
323 Allow retrieval of Search Result-1 information in ZOOM by the use of
324 options that are attached to a result set. ZOOM documentation updated
327 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
328 UTF-8 conversion. Patch by Raj Patel.
330 Added option -m to GFS to control formatting of timestamps in log file.
332 Added 'exit' as synonym for 'quit' in yaz-client
334 Added support for specifying SRW resultSetId + resultSetIdleTime in a
335 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
336 for the new members. Patch by Ko van der Sloot.
338 Added support for SRU POST. It is supported for content-type
339 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
341 Do not build the separate Multi-threaded (MT) library libyazthread.la.
342 Instead make the library libyaz.la multi-threaded. Threading as a whole
343 can still be disabled by configure option --disable-threads. Previosly,
344 with older GLIBCs there were problems with MT libs under Apache. This
345 has now been fixed a long time ago.
347 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
350 CQL module modified to be case insensitive for relations/indexes/operations.
352 Fixed bug in CQL transform code: incorrect value relationModifieder
355 Added 'show all' command for yaz-client which retrieves all results
358 Added new yaz-client, xmles, which takes a (private) OID and
359 a document to be sent as an extended service request.
361 Describe new yaz-client commands wait_response and set_auto_wait.
363 Increase TCP/IP listener backlog from 3 (which I am guessing was
364 copied from the SunOS manual entry way back when) so SOMAXCONN, so
365 that the socket will queue as many incoming connections as it's able
366 to handle ongoing connections. In other words, it will never now
367 refuse a connection that it would be able to handle merely because
368 it's not got around to accepting() enough of the pending connections
369 yet. This is the behaviour anyway under Linux, where the listen()
370 argument is ignored; but not under BSD and on systems such as
371 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
372 YAZ-based servers should now be uniform across operating systems in
375 yaz-marcdump uses 64-bit file access on some systems. This is enabled
376 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
377 This allows yaz-marcdump to read large MARC batches (>2 GB).
379 Modified all YAZ source files - except the source which is auto-generated
380 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
383 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
384 corresponding to the existing *_setl() function. These allow option
385 values containing arbitrary valuues.
387 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
388 ZOOM_resultset_sort() in new applications. Its behaviour is identical
389 except that it returns an indicator of whether or not the sort
390 criterion was accepted (0 for OK, -1 for invalid).
394 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
395 MARC output rather than returning "new" buffer.
397 yaz-client warns about unknown init options.
399 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
403 Added support for SRW sort in Generic Frontend Server. Patch
404 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
405 sortKeys - or NULL if none is provided.
407 Fixed bug #307: It was impossible to specify indefinite/no timeout
408 for ZOOM_event. Special timeout value -1 now means indefinite timeout
411 Added support for multiple languages and charsets to be specified in
412 ZOOM. Each charset/language is separated by a blank. If negotiation is
413 in effect in init-response, Option
414 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
415 Code based on patch by Vasiliy Osadchuk.
417 Fixed bug #306: infinite recursion that occurred when calling
418 yaz_log_level_init as the first call (before other log level or
421 Fixed bug in scan handling in front end server: if preferred-Position-In-
422 Response was non-present, a NULL pointer referece was performed.
426 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
427 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
428 now defined for all those error codes. So instead of putting 109 in
429 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
430 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
432 Modified the yaz-marcdump utility to skip garbage bytes between MARC
435 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
437 Program yaz-client now exits and produces an error message if multiple
438 Z39.50 servers are specified on the command line (none or one allowed
441 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
446 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
448 Fixed bug #272: Preserve spacing for CCL terms.
452 Added support for virtual hosts and multiple backend servers for
453 the YAZ frontend server. The configution is XML based and
454 support specificition of CQL to RPN mappings and explain information.
455 See section "Virtual Hosts" in the YAZ manual.
457 Extended OPAC display utility. OPAC display utility renders
458 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
459 to supplement yaz_marc_decode_wrbuf.
461 Fixed a bug in MARC decoder that could caused it to crash for some
462 invalid MARC records. More diagnostics and warnings where added in
463 XML output (warnings, etc are stored in comments).
465 --- 2.0.34 2005/02/08
467 Fixes for UNIX domain sockets. Bug #261.
469 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
471 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
472 Added yaz_marc_subfield_str which defines subfield lead string which is
473 used in YAZ_MARC_LINE format. Default string is blank+$. Added
474 yaz_marc_endline_str which defines end of fields string used in
475 YAZ_MARC_LINE format. Default string is newline.
477 Experimental support for MarcXChange. This format can be produced
478 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
479 http://www.bs.dk/standards/MarcXchange.xsd
481 Added yaz-client commands scansize that sets maximum number of
482 entries to be returned by scan.
484 --- 2.0.32 2005/01/11
486 Added support for SRW scan in yaz-client and Generic Frontend Server.
488 * Added whereInList member to SRW Scan Term.
490 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
492 Fixed NMEM system to return aligned blocks on the smallest boundaries
493 that are suitably aligned for all possible types on the particular
494 architecture YAZ is being built for.
496 --- 2.0.30 2005/01/04
498 Fixed numerious warnings that was issued with newer versions of GCC.
500 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
501 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
504 Make YAZ Generic Frontend Server slightly faster.
506 Enhance (and reduce) logging for Generic Frontend Server.
508 Revert YAZ log system so that it flushes every write operation
509 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
511 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
512 instead of LOG_, due to name clash with syslog(3). LOG_ are still
513 present. New applications should define YAZ_USE_NEW_LOG=1 - this
514 will effectively disable old definitions.
516 --- 2.0.28 2004/11/09
518 Added yaz_log_time_format which specifies log format using
521 Added yaz_log_module_level which returns mask for a module. Value
522 is non-zero mask a if module is enabled; zero if disabled.
524 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
525 in include/yaz/cql.h.
527 Fixed bug #176: Dont throw diagnostics on empty SRU args.
529 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
531 Fixed bug #172: RPM builds does not enable SSL.
533 Doxyfile.in part of dist. Doxyfile generated by configure.
535 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
536 are given and the corresponding component does not exist.
538 Extend CCL documentation in YAZ reference. Describe r=r.
540 --- 2.0.26 2004/10/01
542 Fixed MARC->MARCXML conversion to properly deal with
543 fields, subfields, indicators having non-ASCII characters.
545 Fixed MARC->MARCXML conversion so that ASCII control characters
546 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
549 Added YAZ GFS support for conversion from Z39.50 surrogate
550 diagnostics to SRW surrogate diagnostics.
552 Bug fix: YAZ GFS did not return schema in explainResponse.
554 --- 2.0.25 2004/09/30
556 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
557 now converts recordSchema to elementSetName as well as schema URI.
559 Fixed bug in COMSTACK that prevented HTTP request packages from being
562 --- 2.0.24 2004/09/29
564 Added CCL facility r=r "range" which is similar to r=o "ordered" but
565 does not require white-space before and after the dash in a range, e.g.
566 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
569 Fixed a few AC_TRY_LINK configure tests that did not operate properly
570 due to new GCC removing "redundant" code.
572 Added yaz-client commands scanpos and scanstep that sets preferred
573 position and step-size for scan.
575 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
577 Added CCL utility ccl_qual_buf which parses one or more CCL
578 spec lines in a buffer.
580 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
581 of name and value - ignoring empty lines and comments.
583 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
585 Added odr_get_element_path which returns current element path for an
586 ODR handle. This utility is useful in error handling or user-defined
589 Added ODR_PRINT utility odr_set_stream which is is a more generic
590 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
591 to a write function and pointer to close function. The close function - if
592 non-NULL - will be called during odr_destroy.
594 Fixed bug in CCL parser where truncation char was not removed from
595 right side when truncation=both was in effect.
597 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
600 --- 2.0.23 2004/08/11
602 Fix buffer overrun in CQL parser when dealing with proximity (%).
604 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
605 to UTF-8/UCS conversion is now only based on codetables.xml.
607 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
609 --- 2.0.22 2004/08/06
611 Add support for more "commit changes" in ZOOM (uses Extended Services).
613 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
616 Yet another small fix for configure of SSL.
618 --- 2.0.21 2004/05/14
620 Fix SSL libs for configure when --with-openssl=DIR is given.
622 --- 2.0.20 2004/05/10
624 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
626 SSL comstack now uses yaz.pem certificate file on server side
627 by default. Certificate filename can be configured by calling
628 comstack function cs_set_ssl_certificate_file before cs_bind is used.
630 Fix bug regarding multiple calls to ZOOM_connection_connect.
632 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
634 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
635 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
637 ZOOM now allows inspection of X509 peer certificate for verification.
638 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
640 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
641 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
642 as "modular" but it simplifies things.
644 Added cs_get_peer_certificate to that returns peer X509 PEM.
646 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
647 NULL if SSL is unavailable.
649 Documentation about MARC decoding tools.
651 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
653 --- 2.0.19 2004/03/30
655 Rename CHANGELOG to NEWS to follow GNU style packing.
657 Fix bug with missing initialization of member in init_diagnostics.
658 This bug affects threaded version of GFS server.
660 --- 2.0.18 2004/03/20
662 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
665 Ensure zlib.dll is packed with Windows install.
667 --- 2.0.17 2004/03/17
669 Fix encoding of xsd:string to use text instead of CDATA.
671 Fix endless loop in CQL parser with unbalanced ".
673 Use a more compact way to store MARC-8 conversion tables.
675 --- 2.0.16 2004/03/16 Debian only
677 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
680 Update CQL parser to use new CQL 1.1 modifiers for booleans and
685 --- 2.0.15 2004/03/01
687 Another fix for decoding of XML packed records.
689 --- 2.0.14 2004/02/25
691 Fixes for Chunked encoding. White space not ignored after length spec.
693 Update NS and use default NS for SRW diagnostic elements.
695 --- 2.0.13 2004/02/23
697 Implement ZOOM_resultset_cache_reset which resets record cache.
699 Implement ZOOM_resultset_sort which sorts a result set.
701 Implement chunked HTTP transfer.
703 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
705 --- 2.0.12 2004/02/16
707 Added member 'schema' to bend_explain_rr structure so that backend
708 can specify explain record identifier. Defaults to Zeerex 2.0.
710 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
712 --- 2.0.11 2004/02/16
714 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
717 Added init command for yaz-client which sends "extra" init request.
719 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
720 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
722 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
724 Make ZOOM error code for "invalid query".
726 Fixed compilation for SSL which wasn't properly enabled for all platforms.
728 --- 2.0.10 2004/02/05
730 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
733 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
735 Added option -p <file> to make Generic Frontend Server to write PID file.
737 Added option -D to put Generic Frontend Server in background on its own.
739 Make ZOOM C recognize option "password". If unset, "pass" is used
740 (for backwards compatibility).
742 Fixed a bug in Generic Frontend Server that could make it crash if a
743 client sets characterSetNegotation bit, but didn't pass negotiation stuff
746 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
747 Must be issued before open, in order to be in effect.
749 --- 2.0.9-6 2004/01/12 Debian/Windows
751 Make the SRU server more picky WRT unknown params, etc.
753 Bug fix: ZOOM scan response didn't return displayTerm - when present.
755 New YAZ client command, options, that sets Z39.50 options.
757 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
758 options from a string of tokens (one token for each option bit).
760 Update SRW diagnostic code messages.
762 --- 2.0.9-5 2004/01/07 Debian/Windows
764 Handle user defined stylesheet for SRW/SRU.
766 --- 2.0.9-4 2004/01/06 Debian/Windows
768 Fix bug in decoding of Content-Length.
770 --- 2.0.9-3 2004/01/06 Debian/Windows
772 Fix a bug with decoding of XML packed records.
774 --- 2.0.9-2 2004/01/05 Debian only
776 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
778 Fix bug in SRW/SRU diagnostics decoding.
782 Fixed bug in Generic Frontend Server which could drop records exceeding
783 preferred message size. Reported and fixed by Irina Dijour.
785 Fixed calculation of package size for structured records in Generic
786 Frontend Server. Reported and fixed by Irina Dijour.
788 Fixed namespace for SRW/SRU diagnostics.
790 Fixed SEGV in yaz-client that occured for HTTP connection errors.
794 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
795 this version is incompatible with version 1.0 and older YAZ SRW/SRU
798 CQL changes to reflect recent changes to the specification:
799 * Documentation talks about context sets instead of index sets.
800 * Documentation talks about indexes instead of qualifiers.
801 * The CQL-to-PQF transformer's configuration file now uses
802 "index.set.name = <attributes>" instead of the old form
803 "qualifier.set.name = <attributes>". (Both forms are still
804 understood but the latter is deprecated.)
805 * CQL terms with no explicit index specified are now interpreted as
806 cql.serverChoice instead of srw.serverChoice (which of course
807 behaves exactly the same.)
811 MARC conversion can now generate ISO2709 output in another
812 character set. yaz-marcdump uses this facility if you invoke it
815 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
816 functions from there can be used from C++.
820 Frontend server now transfers memory from decoded packages to stream
823 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
824 references to show up.
826 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
827 the ZOOM Abstract API. The older names for the same options are still
828 also supported for the benefit of old applications.
830 ZOOM-C supports "implementationId" and "implementationVersion" options
831 to go along with "implementationName". These allow the user code to
832 specify identification strings to be sent to servers.
833 Add OID for the new ExtLite attribute set.
835 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
836 as requested/supplid by Ere Maijala <ere@atp.fi>
838 For generic frontend server, reverse the order of
839 "toolkit-supplied / application-supplied" strings sent as implementationId,
840 Name and Version. Also, remove the spaces around the slash. This brings
841 the GFS in line with the behaviour of ZOOM-C on the client side.
843 Add function ZOOM_scanset_display_term.
845 yaz-client shows scan displayTerm if present.
847 Utility yaz-iconv is now installed by default along with the man page
850 Extend configure check for OpenSSL to use pkg-config where available (such
853 Incorporate patch by Morten Bogeskov which allows a Unix file socket
854 server to specify uid/gid/mask for socket using the format
855 unix:[user=uid,][group=gid,][umask=mask,]file=path
856 If file= is omitted the existing format is assumed, e.g.
858 in which case the mask is 0666 (rw for everybody).
860 Major restructure of YAZ source. All source in libyaz is in src directory.
861 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
862 util (utility programs such as ASN.1 compiler, yaz-marcdump).
864 Added man page for utility yaz-marcdump (used to be called marcdump).
865 yaz-marcdump is installed by 'make install'.
867 Fixed a memory leak in Generic Frontend Server that occurred when decoding
868 of incoming package failed.
870 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
872 Change prototype of odr_perror: add const to message string.
874 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
876 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
877 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
878 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
879 DNS lookup. There should not be any compatibility problems with this
880 assuming that blocking=1 or 0 is used.
882 Fix bad reference in UNIX comstack in function cs_addrstr.
884 Fix for compilation on AIX.
886 The generic front-end server (server/seshigh.c) now supports returning
887 Init diagnostics to the client in User-information-field, in
888 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
893 Allow any CQL relation (not just all,any,exact,scr).
895 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
896 that features the same UI.
898 Implemented command update0 in YAZ client which is equivalent to
899 update but uses old of Ext Update ASN.1.
901 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
902 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
903 Previously no OID was used for this info.
905 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
906 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
907 returns 'malformed search term' otherwise.
909 SortResponse member resultCount now set to NULL in sort handler of
912 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
915 Add three new utility functions for translating OIDs between various
916 formats -- symbolic name such as "Usmarc", minus-1-terminated int
917 arrays and dotted strings such as "1.2.840.10003.9.5.1":
918 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
919 char *oid_to_dotstring(const int *oid, char *oidbuf);
920 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
922 Reverted modifications for ES Update definition for z_IU0Update
923 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
924 is back to YAZ 2.0.2.
926 String value attributes for CCL parser.
928 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
929 which their FirstSearch server returns in Init responses, sometimes
930 carrying useful diagnostic information when Init fails. This has the
931 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
932 "z39.50/oclcui.asn", where its definition is somewhat different from
933 what OCLC document on their web-site, as required to interoperate with
936 Support for anonymous authentication in yaz-client. Use the command
939 * Fix the OID of the Index Data-local "admin" Extended Service from
940 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
941 the 1000, which indicates a locally-defined OID, was a mistake.
945 Fix CCL directive @case handling so that it affects string match for
946 both CCL keywords and qualifiers.
948 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
949 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
950 Decoder has been updated with ASN.1 changes as listed in
951 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
952 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
953 z_IUUpdate, remains unchanged.
955 ZOOM_record_get may now return a record in a specific character set.
956 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
957 "from" is the character set of record as returned by target. "to" is
958 the character set to be returned. If omitted, "to" is UTF-8.
960 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
962 New ODR utility, odr_getelement, which returns name of element for
963 which encoding/decoding failed.
965 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
966 in cases where a required element was omitted.
968 Bug fix: some MARC8 sequences were not converted.
970 New ZOOM option "step" which specifies number of records to be
971 retrieved in one chunk. Used in conjunction with "start" and "count".
973 SRW support for yaz-client. Use scheme http: to use it, e.g.
976 yaz-client no longer does (un)intelligent character set conversions
977 by default. Can be enabled with charset and marc_charset commands.
979 xmalloc trace fix for 64-bit systems such as DEC alpha.
981 Solaris 2.6 compile fix.
983 New function, cql_strerror() translates SRW error codes, as returned
984 by cql_transform_error(), into human-readable English strings. Used
985 in yaz-client diagnostics when appropriate.
987 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
988 converts it into a type-1 query which is sent to the server. This
989 makes CQL available for use with all Z-servers, as opposed to the tiny
990 minority that can handle CQL queries themselves.
994 New Debian package layout similar to the Redhat Package layout.
996 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
997 and search result respectively.
1001 Redhat package is now several packages: libyaz (runtime libraries),
1002 libyaz-devel (development and documentation, and yaz (utility programs).
1003 Package spec file by Morten Bøgeskov.
1005 New member 'schema' in struct bend_fetch_rr which the name of requested
1006 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1007 handler MAY set this to reflect the schema of the returned record.
1009 New member 'display_term' in struct scan_entry. GFS now sets member entries
1010 and allocates scan entries to be filled by user scan handler. In previous
1011 version, entries member was allocated by the scan handler. That still works,
1012 but the GFS will ignore member display_term - assuming it was NOT set by
1013 the handler. The fact that the GFS now allocates the entries both allows
1014 for new members and makes a scan handler easier to write.
1016 Fix CQL lex buffer overflow.
1018 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1019 SRU default recordPacking is string.
1021 SRU protocol support for frontend server.
1023 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1025 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1027 Added scan for the ZOOM shell (zoomsh).
1031 * String Identifers for Schemas (Amendment 5).
1032 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1033 Old definition for schema
1034 Odr_oid *schema; /* OPT */
1039 Z_InternationalString *uri;
1040 #define Z_Schema_oid 1
1041 #define Z_Schema_uri 2
1044 * resultCount parameter to Sort Response (Amendment 1).
1045 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1047 Support for SRW 1.0 over HTTP. This is an optional feature and
1048 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1051 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1052 on the same port. SRW SearchRetrieveRequests are mapped
1053 to bend_init,bend_search,bend_fetch,bend_close.
1055 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1057 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1058 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1060 ZOOM connections are SRW based if schem http is used for hostname
1061 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1062 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1064 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1065 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1066 distance=n, order=true/false, relation=le, prox unit=word. If
1067 n is omitted, distance 1 is used.
1069 Fixed problem with C compiler include path in wrong order.
1071 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1072 on Solaris. Patch from Ko van der Sloot.
1074 New MARC decode API. All new functions operate on a yaz_marc_t
1075 handle. The most important new functions are: yaz_marc_create,
1076 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1077 decode and destroy respectively. Decoder can produce formats
1078 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1079 include/yaz/marcdisp.h.
1081 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1082 to UTF-8, UCS-32, wchar_t or Latin-1.
1084 * Prototypes for yaz_iconv_-functions moved to separate header
1085 include/yaz/yaz-iconv.h.
1087 Make a few private functions 'static' in unix.c. This prevents
1088 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1090 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1091 are set when Init Response is received.
1093 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1094 but returns diagnostic set as well.
1096 New function yaz_strerror which is a portable wrapper for
1097 strerror/strerror_r/GetLastMessage.
1099 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1100 is returned for MARC. If type is "oai", then OAI MARC is returned.
1102 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1105 --- 1.9.2 2002/11/26
1107 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1109 Fix bad race conditions on SIGTERM and terminate gracefully in
1112 Move retrieval (data1) module to Zebra since nobody seems to be
1115 Add GRS-1 render for ZOOM using same format as yaz-client.
1117 --- 1.9.1 2002/10/05
1119 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1121 Fix broken ESpec handling in data1 module.
1123 SGML reader parses comments and makes them part of the data1 tree.
1125 Added several type casts so that YAZ compiles as C++ code.
1127 ZOOM didn't handle PDU encoding failures properly.
1129 Added more Bib-1 diagnostics (approved extensions).
1131 GNU configure: better check for iconv.
1133 More portable use of accept, getpeername. Check for socklen_t. Use
1134 int/size_t if socklen_t is not defined.
1138 PQF parser rejects bad queries - including those with extra
1139 characters in them. PQF parser used to silently ignore that.
1140 Cleaner API for PQF added, which allows you to get detailed
1141 error information for bad queries (see yaz/pquery.h).
1143 Fixed bug in ZOOM_record_get for type "database".
1145 Implemented mini iconv library supporting conversions between
1146 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1148 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1150 --- 1.8.9 2002/08/20
1152 Fixed ZOOM C record cache so that preferredRecordSyntax and
1153 elementSetName is used to check for already fetched records.
1155 --- 1.8.8 2002/08/02
1157 Added three members in bend_initrequest structure to facilitate
1158 character set negotiation.
1160 Fixed a bug in frontend server that could cause indefinite
1161 loops under rare conditions.
1163 Revised character set utilities (charneg.h) so that encoding
1164 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1166 For PQF, directive @term <type> sets term type for Scan/Search.
1167 Here <type> is general, string, numeric, null. The term type
1168 is inherited - just like @attr.
1170 New call odr_set_charset that sets character set conversion for
1171 international-strings on a ODR stream. Prototype is:
1172 int odr_set_charset(ODR o, const char *to, const char *from);
1173 The InternationalString is still represented as C string in YAZ
1174 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1175 won't). On the protocol level, you can use any encoding.
1177 Support for UNIX sockets in ZOOM.
1179 Solaris recv sometimes returns errno == ENOENT. It is treated as
1180 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1182 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1183 both client and server. Code by Morten Bøgeskov.
1185 --- 1.8.7 2002/05/22
1187 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1188 that they can be used directly from Visual Basic. You must recompile
1189 your windows APP if you're using ZOOM.
1191 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1192 Commands "lang" and "charset" sets language and character set respectively.
1193 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1194 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1196 Attributes from multiple CCL fields may be OR'ed rather than merged
1197 using directive "@field or". Fields are still merged by default -
1198 equivalent to "@field merge".
1200 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1203 Fixed bug in zget for parameter ExtendedServicesResponse.
1207 --- 1.8.6 2002/03/25
1209 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1211 Client displays USR.1:SearchResult-1 (hits per term).
1213 Additional Search Info for search in Generic Frontend Server.
1215 Fixed CCL parsing of "field=s".
1217 WIN32 installer - using the excellent NSIS software from nullsoft.
1219 Fixed CCL parsing of "field = - <number>".
1221 Added function yaz_marc_decode that decodes MARC for line mode
1222 display or XML (similar to that used by JZKit).
1224 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1225 Z39.50. But ISO/ILL was, however.
1227 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1228 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1230 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1231 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1233 --- 1.8.5 2002/02/03
1235 New YAZ client features: Command completion and new commands:
1236 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1237 Code provided by Jacob Poulsen.
1239 New call oid_trav, that visits all registered OIDs via callback.
1241 Function ZOOM_record_get now returns const char pointer rather than
1242 void pointer. It saves a lot of type casts.
1244 For YAZ client, command "auth" now allows you to set authentication
1245 in IdPass style. It is enabled when three tokens are given - order
1246 is user, group and password.
1248 Fix memory leaks in MARC record handling for ZOOM.
1250 New option for YAZ client, -k <kilobytes> that sets
1251 maximum record size. Similar to -k option for generic frontend
1252 server and yaz-ztest.
1254 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1256 Prefix query parser reports "fail" when bad attribute set is given.
1258 Fix in MARC decoder. Proximity logging. Fix for attribute set
1259 in scan handler for server. Patches by Shigeru Ishida.
1261 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1264 Configure option --with-openssl=<dir> now works when a directory is
1265 specified. Patch provided by Morten Bøgeskov.
1267 New option for YAZ client, -u <auth>, that sets authentication.
1269 ZOOM fix: error information was sometimes "missing", since error
1270 was cleared/reset too when it shouldn't.
1272 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1274 --- 1.8.4 2002/01/04
1276 Scan for ZOOM API. New object ZOOM_scanset. New functions
1277 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1278 ZOOM_scanset_destroy.
1280 New ZOOM function, ZOOM_connection_last_event, that returns type
1281 of last event (such as "receive data", "send data", "apdu received",
1284 New ZOOM option, schema, that specifies schema for retrieval.
1286 New CCL feature. Qualifiers can be aliases for one or more
1287 other qualifiers (if more than one is given, OR is used).
1289 ZOOM uses named result sets if target supports it.
1291 Two new YAZ client commands: . (dot, which sources a script of YAZ
1292 client commands), and ! (to execute shell command.). Implemented
1295 Working on Debian packages.
1297 --- 1.8.3 2001/11/19
1299 YAZ client enables named result sets only if target supports it.
1301 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1303 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1304 with key="host" to get same result.
1306 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1307 Function Z3950_resultset_record(s) returns references to records
1308 "owned" by resultset. To become owner use Z3950_record_clone.
1310 Function z_ext_record handles Extended Services. Thanks to
1313 --- 1.8.2 2001/11/12
1315 CCL Parser fix: ignore token comma when dealing with and-lists.
1317 Documentation updates for COMSTACK.
1319 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1320 Changed prototype Z3950_records. For some functions, int parameters
1321 were changed to size_t.
1323 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1326 New MARC decode/display function, marc_display_exl, which properly rejects
1327 non-ISO2709 records. YAZ client uses it.
1329 --- 1.8.1 2001/10/29
1331 Fix bug: local attribute set wasn't set correctly in PQF strings.
1335 * Old Z39.50 codecs no longer supported.
1337 Added ZOOM C binding. See http://zoom.z3950.org/
1339 Renamed states for COMSTACKs to avoid confusion with events.
1341 Implemented cs_look and proper cs_rcvconnect.
1343 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1345 Configure detects POSIX threads on OpenBSD.
1347 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1348 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1350 When error is returned from present handler, non-surrogate diagnostic
1351 is returned in present response (and fetch handler is no longer called).
1353 * Minor adjustments to pquery parser (PQF). Token characters may be
1354 escaped by using backslash (C-style).
1356 PQF parser allows string attribute values to be specified. For @attr,
1357 non-numeric characters after the equal-sign are treated as strings
1358 (e.g. @attr 9=title).
1360 CCL trunction character may be defined (@truncation in file)
1362 * function zget_ExtendedServicesRequest sets waitAction to
1363 waitIfPossible (was wait).
1365 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1368 CCL operator names may be set in field definition files (CCL_bibset).
1369 See ccl/bib1 for an example.
1371 Fixes in ASN.1 compiler for C++ compatibility.
1373 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1374 and "op_or" to avoid conflict with C++.
1376 Fixed problem with GNU readline detection on Redhat 7.0.
1378 Added step-size for Scan backend handler.
1380 Fixed bug that made the frontend server crash when no attribute
1381 set was specified for scan.
1383 Front-end server automatically switches to original working directory
1384 when installed as an NT service. Previously -w had to be specified to
1387 Added extended attributes for retrieval module (data1), so that data1
1388 records carry d1_readXML/SGML attributes. d1_read also supports
1389 null-data rules ( <tag/>)
1391 On UNIX when POSIX threads are available, a separate library libyazthread
1392 is created. Programmers should link with that library and the yaz library
1393 when using threads. The reason for the split was that some applications
1394 on Linux, such as Apache, doesn't work well when using shared objects that
1397 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1398 (or any frontend server) in SSL mode by specifying ssl: followed by
1399 address. Only tested on UNIX.
1401 Added feature for CCL module. Virtual structure s=al or s=ol generates
1402 and-list and or-list respectively instead of phrase search.
1406 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1407 log_mask_str. This was done to avoid name conflicts with other libraries
1408 (such as other PHP extensions).
1410 Added raw OID member for preferred record syntax (request_format_raw)
1411 and returned record syntax (output_format_raw) for backend fetch method.
1413 Config file yaz-config now accepts options so that it returns specific
1414 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1416 Shared library support for UNIX using GNU libtool.
1418 * Modified backend interface. Request/Response struct's replaced by
1419 one read/write C struct. For example bend_fetchrequest and
1420 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1421 Every handler - even search has to be registered in bend_init
1422 handler. This means that the YAZ library no longer refers to
1423 external functions and it makes it possible to make the whole
1424 thing a single DLL/SO.
1426 Added Segment handler for backend server.
1428 Added Zmbol/Zebra administrative functions to YAZ client.
1430 Threaded frontend server on UNIX (when POSIX Threads are available).
1431 Starting the server with option -T enables multi-threading.
1435 Added configure option --enable-comp/disable-comp to control use
1436 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1437 located in sub directory asn.
1439 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1440 in ${exec_prefix}/bin along with the other programs yaz-client and
1443 GNU automake used to maintain makefiles.
1445 Added several OID's.
1447 Changed retrieval module so that we can load records with no abstract
1448 syntax defined. Tagpaths in these records are fully composed of string
1451 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1455 On UNIX, the generated makefile now supports a proper 'make install'.
1456 The prefix can be set via GNU configure to set the install location
1457 (default is /usr/local).
1459 * YAZ programs client and ztest were renamed to yaz-client and
1460 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1461 locations, such as /usr/bin,/usr/local/bin,etc.
1463 * YAZ Header files were moved from include to include/yaz. YAZ Header
1464 files are referred to as include <yaz/log.h> rather than <log.h>.
1465 The YAZ include path (-I ..) is therefore the same as before. Programmers
1466 should update their #include statements or use -Ipath/include/yaz
1467 instead. The main motivation for doing this change is that YAZ header files
1468 can be installed in "standard" locations /usr/include,/usr/local/include
1469 without introducing conflicts, since ALL YAZ header files are stored
1470 in subdirectory yaz (under /usr/include for example).
1472 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1473 rather than project/workspace files. We switched because project files
1474 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1477 Changed name of logging function, logf, to yaz_log, to prevent name
1478 clash with some math-log functions. The YAZ header log.h defines logf
1479 to yaz_log (#define) so there should be no incompatibilities by this
1482 Added bend_start/bend_stop handlers for server. These handler are
1483 called on start/stop of server. For windows they are called whenever
1484 a service is started/stopped.
1486 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1487 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1488 in util/yc.tcl. The auto-generated C code structures are, in a few
1489 cases, incompatible with the old decoders. There are differences in the
1490 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1491 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1492 The preprocessor variable ASN_COMPILED is defined when the compiled
1493 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1494 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1495 wish to use the old encoders/decoders you can specify --disable-yc
1498 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1499 version so that it supports both new - and old version of DB Update
1501 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1502 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1503 change. The name parameter can be set to 0 in which no name is specified
1504 for the construction. The macros odr_implicit and odr_explicit sets name
1505 parameter to zero for the construction involved. New macros
1506 odr_implicit_tag and odr_explicit_tag are similar to the others,
1507 except that a name parameter is added. For programmers' that don't use
1508 ODR they probably only need to change the call to z_APDU and z_External.
1510 Added access control facility by interfacing the TCP wrapper library.
1511 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1512 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1513 name of the daemon and enables the access control as specified in
1514 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1516 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1517 den Dool <H.M.vdnDool@kub.nl>.
1519 Added reference ID parameter to most functions in server API - refer
1520 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1522 Changed name of ccl library to libccl.a (was ccl.a).
1524 Fixed bug in decoder for Explain (Category TargetInfo).
1526 Added support for GNU readline in client. Thanks to Jacob Poulsen
1527 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1529 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1530 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1531 IMPLEMENTATION! This change was made to the development version before
1532 the ZIG decided to retract the amendment. If any users MUST be
1533 compatible with the original Update definition, PLEASE CONTACT US, and
1534 we will include a separate definition corresponding to the old Update
1535 ES. Note that because of the change to the ASN.1 of the
1536 TaskPackageRecordStructure we cannot define a single structure that
1537 will support both versions.
1539 * Added const modifier to buffer parameter for some ODR/BER encoding
1540 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1541 completeWAIS, odr_dumpBER.
1543 Fixed bug in client.c which caused a crash when a scanResponse didn't
1544 contain positionOfTerm.
1546 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1547 * will cause an error in a client if a non-YAZ target sends both a
1548 * list of Scan entries and non-surrogate diagnostics.
1550 Retrieval module enhancements. Tag sets may be typed in the reference
1551 to it. From the .abs-file the "tagset" directive takes a third optional
1552 integer type for the tag set referenced. From a .tag-file the "include"
1553 directive takes a third optional type as well. The old "type" directive
1554 in the tag set itself is still recognized but acts as the default type
1557 Backend interface change. Individual Scan terms returned from bend_scan
1558 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1559 in include/backend.h.
1561 Retrieval module enhancements. Multiple tag sets and attribute sets may
1562 be specified in abstract syntax specs. Revised the error/warning for
1563 logging messages reported by the retrieval module when reading the
1566 Object Identifier system (oid_..) changed. The API is backwards
1567 compatible but the oid-routines now allocates new OID's when needed.
1568 Raw OID's may be specified in oid_getvalbyname.
1570 YAZ now uses GNU configure to generate Makefile(s).
1572 * Minor changes in some of the member names of DeleteResultSetRequest and
1573 DeleteResultSetResponse. See include/proto.h.
1575 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1576 and added member 'languages' in TargetInfo (which was missing).
1578 Changed the way attribute sets are handled in the retrieval
1579 module. These are now cached, just like the abstract syntaxes
1582 Changed YAZ so that it links with compiled ASN.1.
1584 Added Explain-schema definitions and mapping routines. The following
1585 Explain categories have been implemented: AttributeDetails,
1586 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1588 Fixed minor bug in Windows version of Server Library.
1590 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1592 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1594 Added EXTERNAL: UNIverse Resource Report (non-standard).
1596 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1597 ENUMERATED and SET OF.
1599 * Added 'const' to some of the char pointer arguments for the
1600 functions, data1_read_node, data1_getelementbytagname,
1601 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1604 Fixed bug in data1_insert_taggeddata - the last_child member of
1605 parent wasn't initialised.
1607 * Changed data1_read_record and data1_read_node so that the supplied
1608 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1609 doesn't refer to any parts of the "SGML"-buffer.
1611 Fixed bug in server library (Windows version of statserv_remove).
1613 * Changed code so that it compiles as C++. The type definition
1614 of Odr_fun which is a member of Odr_arm was changed. The result is,
1615 that an explicit typecast is needed for the fun pointer when
1616 using Odr_arm - as in:
1617 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1619 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1621 Implemented the new structured date and time definition as approved
1622 by the ZIG. Added schemaId element to the specificTag in Espec-1
1623 (also approved at the last ZIG). Thanks to RVDM.
1625 Added some Object identifiers (RVDM).
1627 Changed the Update Extended Service (RVDM).
1629 Added command "refid" to client which specifies referenceId for
1630 the following requests.
1632 Implemented extended service handling for server. See ztest.c
1633 for an example as well as backend.h. New handlers are registerd
1634 in the Init handler.
1636 * Changed interface for sort in server.
1638 Added new members to statserv_options_block. It allows a server
1639 to read options from another source than just the command line. Thanks
1640 to Charles Woodfield.
1642 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1643 renamed to zboolean. Some C++ compilers complained about the name.
1645 Minor changes to gils.abs. Added index 's' (sort) on title
1646 and date/time-last-modified.
1648 --- 1.4pl2 1998/1/30
1650 Fixed bug in server library regarding inetd mode (-i). This bug
1651 was introduced by release 1.4.
1653 --- 1.4pl1 1998/1/29
1655 Added sort facility in client and backend server interface.
1657 Fixed problem with dependencies in Makefile(s).
1659 Fixed bugs for encoders/decoders of extended services and
1662 Implemented sub-tree feature for schemas. Sub-trees are
1663 referenced in *.abs-files. See explain.abs for an example
1664 of the use of this feature.
1666 Modified bib1.att; local attributes for ANY didn't include
1667 ANY itself (only affects use of the retrieval module).
1669 Fixed bug in plain SGML reader in function data1_read_node:
1670 tags with prefix "var" was incorrectly interpreted as variants.
1672 Added feature "sub-schemas" to enable references to - and definitions
1673 of - group of elements.
1675 * Removed member parent from type data1_element (in data1.h).
1677 Implemented function odr_nullval() that returns the value of
1680 * Removed member num_children from data1_node (in data1.h).
1682 Made NT service interface part of the server library. The
1683 function statserv_main uses the NT service when required and
1684 calls the statserv_start / statserv_close routines.
1686 Routine zget_SearchRequest and zget_PresentRequest fills
1687 resultSetName/Id member with "default" instead of "Default".
1689 Fixed memory leak in server. Request queue member wasn't freed.
1691 Fixed nmem_exit so that memory is freed.
1695 Revised the CCL parser utility to be thread safe.
1697 Added function, oid_ent_to_oid, to replace the function
1698 oid_getoidbyent, which is not thread safe.
1700 * Added nmem_init and nmem_exit to initialize and release
1701 NMEM resources. Function nmem_init should be called once in the
1702 initial thread before NMEM/ODR is used. statserv.c and client.c
1703 have been changed accordingly. The change was necessary to make
1704 NMEM thread safe. The NMEM memory pool is shared amongst threads
1705 in a process. Unix-based applications will still work fine without
1708 Added NT Services interface for the the Z39.50 (statserv) Server.
1709 Refer to the ztest.c source on the usage.
1711 Windows 95/NT port using MSVC5.0. Project files are included in the
1714 * Defined new 'global' handle for the retrieval (data1) system. The
1715 new handled, data1_handle, describes the state of the data1 system.
1716 This handle is passed as first argument to virtually all
1717 data1 related routines. The functions data1_create and data1_destroy
1718 creates and destroys a data1 handle respectively.
1720 Added ODR encode stream member to all backend request structures
1721 init, search, scan etc. This stream should be used to allocate all
1722 memory used for the response when thread safe operation is needed.
1724 Changed the comstack utility, cs_addstr, to be thread safe. The
1725 returned hostname string returned by the function is now part the
1728 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1729 function. The cs_straddr takes a COMSTACK handle as argument, so this
1730 function must be used after cs_create and before bind/connect.
1731 This function is thread safe.
1733 Moved test server to 'ztest' directory - generic server code still
1734 in 'server' directory.
1736 Made prefix query (pquery.c) utility thread safe.
1738 Added new function modifier YAZ_EXPORT to 'export' public DLL
1739 functions when using windows (see include/yconfig.h).
1741 Added definitions to the OID database (util/oid.c) (RVDM).
1743 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1745 Added call to ccl_rpn_delete in client program.
1747 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1748 release of RPN structure.
1750 Added support for C++, headers uses extern "C" for public definitions.
1751 With input from RVDM.
1753 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1754 Thanks to Ronald van der Meer (RVDM).
1756 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1758 Added support for private extensions to the OID database
1759 (oid_setprivateoids()). Thanks to RVDM.
1761 Added optional, physical ANY (key replication)
1763 Fixed null-reference problem in GRS-1 output filter.
1765 Proximity operator added to Prefix Query Format (PQF).
1767 In test client command "base" accepts multiple databases.
1769 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1773 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1775 Smallish bug-fixes in the new encoders/decoders (explain).
1777 Bug fixed in DeleteRequest.
1779 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1781 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1783 Added SOIF syntax (using private OID for now) to retrieval module and client.
1785 Added Update extended service.
1787 Added SearchResult-1 additional info structure.
1789 Added optional CCL (ISO8777) interpreter as separate module. Available
1792 --- 1.2 1996/6/10 (1st anniversary release)
1794 Added Summary record syntax. Lightly tested.
1796 Added OPAC record syntax. Untested.
1798 Added ResourceReport service encoders/decoders. Untested.
1800 Fixed bug in z_Unit - wrong tagging on unitSystem.
1802 Fixed bug in the DiagRecs decoder.
1804 Added options for max PDU size and session timeout to frontend-server.
1806 Added documentation of query-language parsers and other supporting utilities.
1808 [frontend-server] Added Attribute set to the bend_scanrequest API.
1810 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1811 surrogate diagnostics were generated.
1813 [retrieval] Allow multiple local values for attribute.
1815 [retrieval] Allow multiple attributes per element in .abs files. index type.
1817 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1819 --- 1.1pl2 1996/4/10
1821 Minor changes, mostly specific to Zebra's requirements (retrieval)
1825 Repaired bug in frontend server when running multiple listening
1826 endpoints in dynamic mode.
1828 z_External() now won't break if a known, ASN.1 value comes encapsulated
1829 in an octet-string. The value will pass through unmodified in an Odr_oct.
1831 Added a bit of code to the demo client to decode & display
1832 ASN.1-structured records represented in the octet-aligned branch of
1833 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1835 Added z_ext_getentbyref() to the ASN module. Doc updated.
1837 * Completed the SCAN definition in the ASN module. This may break SCAN
1838 code based on older YAZ-versions at compile-time. The fix is easy -
1841 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1842 under the SCAN definition. Remember to initialize this, server-people.
1844 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1845 that this does not extend to ODR and ASN.
1847 Comstack allows insertion of established socket (primarily for
1848 inetd-operation of servers). Doc updated.
1850 Front-end server can now start from the inetd in TCP mode. Doc
1853 --- 1.0pl4 1996/1/24
1857 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1858 the rank and record number.
1860 Adjustments to the frontend server.
1862 Fixed diagnostic BER dumper. It ignored the file argument.
1866 Various changes to retrieval module.
1868 Changed the union discriminators of the protocol files from enums to
1869 ints paired with #defines.
1871 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1874 *Changed operator in the RPN structure to 'roperator', again to avoid a
1877 Fixed problems in Explain decoders/encoders.
1879 --- 1.0pl2 1995/12/6
1881 Memory bug in log module fixed.
1883 --- 1.0pl1 1995/12/5
1885 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1887 Bug in Explain DatabaseInfo module fixed.
1889 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1893 The shift to v1.0 signals that we now consider the *core* functionality
1894 of YAZ reasonably stable (the core being more or less equivalent to
1895 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1896 tested (Explain not at all - though that will happen soonish).
1898 Minor changes to code to support Windows port.
1900 Various minor changes after we're getting to use GRS-1 & co. more.
1902 Added Espec-1 format.
1904 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1905 of the protocol and it cannot be selected when encoding (maps into 'string'
1906 when decoding). Needed to talk to some servers.
1908 Demo client can request simple element set names.
1910 Added Diagnostic Format encoders/decoders.
1912 Added simple Close handling to frontend server (no hooks for resource
1913 reporting yet), and demonstration client.
1915 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1917 --- 1.0b3 1995/08/24
1919 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1920 handled incorrectly when records were requested in the searchResponse. This
1921 will only affect you if you use the frontend-server.
1923 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1924 Test-client will ask for and print GRS1. Ztest will return dummy records
1927 Added Explain encoders/decoders to the service-level API. Untested.
1929 Added Extended Services: Item Order encoders and decoders to the Service-
1930 level API. Untested. We could use a recent copy of the pertinent bits
1931 of the ILL protocol to add those bits.
1933 Added diagnostic format 1 encoders/decoders to the service-level API.
1936 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1937 odr_cons.c, which causes a more correct output.
1939 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1940 was always set to 0 when no records were requested in the searchRequest.
1942 * Added better external-handling. This shouldn't harm old code that
1943 *encodes* externals. It can break code that looks for a
1944 'single-ASN1-type' representation, since those types that are known
1945 are now decoded immediately. Look at the SUTRS sample code in
1946 seshigh.c and client.c. Documentation updated.
1948 Handling of structured records in bend_fetchresponse. Length -1 marks
1949 structured record, type is deduced from format field.
1951 --- 1.0b2 1995/06/27
1952 Fairly quick maintenance release to add SUTRS support.
1954 Fixed handling of SUTRS records in the demonstration client.
1956 * Added format field to the bend_fetchrequest and bend_fetchresponce
1957 structures of the backend API (frontend server). When the record is
1958 returned, the value of the format field is mapped to an OID. The
1959 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1960 of the record. The special value VAL_NONE in the bend_request means
1961 that no specific format was requested by the client. Documentation
1962 updated accordingly. Test server (ztest) will return a fixed dummy
1963 SUTRS record if your client requests SUTRS.
1965 Documentation updated accordingly.
1967 You can now set external libraries and RANLIB support in the top-level
1971 First public release.
