2 Updates for SRU Update by Ko van der Sloot:
3 1. Changed name from "operation" to "action"
4 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
5 versions in the code, marked as 'backward compatible'.
6 3. Added diagnostics for SRU Update.
10 Implemented yaz_filepath_comp which splits a path into file path
11 components (required by Zebra 2.0.3+).
13 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
14 BSD inspired license until now so this should not have any real impact on
15 anybody. See http://www.opensource.org/licenses/bsd-license.php
17 Fixed bug #687: Missing log lines.
19 Fixed bug #678: CQL to PQF translation does not preserve double-quote
22 Fixed bug #689: SRU diagnostics to be added.
24 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
25 whether a connection is idle (no more work do do).
29 Change type of optval from long to int for invocation of setsockopt with
30 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
32 Added support for specifying the max log file size for the Generic
33 Frontend Server. The size is given with option -r.
37 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
41 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
44 Fixed bug in Generic Frontend Server that could cause a server to stop
45 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
47 For the generic frontend server, the maximum record size is used as maximum
48 size of incoming packages (SRU + Z39.50). The value until was previously
49 only used in Z39.50 Init negotiation and, later, in a session controlled
50 sizes of records returned. This is controlled using -k option. It can be
51 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
55 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
58 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
60 New option for yaz-marcdump -lpos=value which allows setting a portion
61 of MARC header to a certain value.
63 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
65 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
66 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
70 Fixed problem with SRU mode type (soap, get, post) for yaz-client
73 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
77 Fixed MARC ISO2709 encoding routines to deal with character set
80 Minor changes to GFS logging. Database included in search request log
83 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
84 cached/multiple records.
86 Shared libraries are built by default on Unix+configure.
88 Changed cql2pqf transformation to use a different evaluation order. The
89 new order is: always, relation, structure, position, truncation, index
90 and relationModifier. Old order was: always, relation, relationModifier,
91 structure, index, position, truncation. Note that the the latter ones
92 override former ones for identical attributes.. The new scheme means that
93 it is possible to override any existing attribute with a relationModifier.
94 And also that it is possible to override everything for the index rule
95 (except the ones listed in relationModifier). No order is perfect but this
96 one, we believe, covers more real cases.. The "always" should have been
97 called "default", since the attributes there can be overridden with all
100 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
101 compilation phase, but also for yaz-config --cflags output. This allows
102 us to have public headers with Libxml2 stuff in them . It should also,
103 eventually, make Libxml2 checks redundant in packages using YAZ, such
106 --- 2.1.22 2006/06/15
108 Changed SRU update structure bend_update_rr so that SRU diagnostics are
109 stored in uri, message and details.. Previously diagnostics were stored
110 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
111 compatibility.. but he's probably the only one affected, so.
113 Added support for CCL, compiled on the client side, in ZOOM-C. This
114 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
115 input; the resulting query objects can be used for for searching with
116 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
118 YAZ' configure searches for OpenSSL by default.
120 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
121 SL_CTX_use_certificate_file. See
122 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
123 for more info. Thanks to Ko van der Sloot.
125 --- 2.1.20 2006/06/02
127 Bug #600: SRU GET, POST support for yaz-client. Introduced
128 command 'sru' which selects method SOAP/GET/POST.
130 Allow missingValueAction to be specified for the sortspec string -
131 function yaz_sort_spec. By default, the missing value action is null.
132 Use ! to specify "abort". Use = followed by stringvalue to specify default
135 Ensured that Present-handler (if defined) is called in GFS before any call to
136 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
137 searchRetrieve requests.
139 Documentation for YAZ is now based on the Docbook XML/XSLT using
140 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
141 is no longer depending on jade/openjade or docbook-to-man scripts.
142 PDF is no longer part of the distribution - but can optionally be
143 made using DSSSL/jadetex or FOP.
145 Added retrieval handling support in Generic Frontend Server to support
146 conversion between MARC/XML as well as XSLTtransforms. See
147 etc/yazgfs.xml for an example.
149 Added Authentication support to Generic Frontend Server in SRU
150 mode. Authentication using HTTP Basic is supported, as is the use
151 of 'x-username' and 'x-password' parameters in the request itself.
153 Added support for a new character set MARC8s identical to MARC8 except
154 that it converts combined characters to single Unicode characters in the
155 Latin-1 range (when possible).
157 --- 2.1.18 2006/04/24
159 ASN.1 compiler 0.4: generates brief Doxygen file header for
160 generated .h/.c files.
162 Utility yaz_iconv now supports conversion to MARC-8.
164 New facilities for the MARC module. The reading - and writing of
165 content are separate methods for the yaz_marc_t handle. The following
166 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
167 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
168 format). Write functions have prefix yaz_marc_write_.. The existing
169 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
170 available. Removed support for OAI-MARC and simplexml (not the
171 simplexml from PHP5).
173 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
174 to be returned for this connection.
176 --- 2.1.16 2006/03/31
178 Allow multiple languages and charsets to be specified with
179 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
180 negcharset iso-8859-1,utf-8
182 Translation of proximity nodes from CQL into PQF now works.
184 Moved to automake 1.8, 1.9.
186 Added function yaz_log_set_handler which allows a log handler to be
187 installed. This handler will be called for all log messages. Output
188 to file is also produced; but that can be disabled by passing NULL
189 fname to yaz_log_init_file.
191 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
193 For SRW (including GFS), accept application/soap+xml as content-type
196 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
197 produces NO stylesheet reference even if a default stylesheet is specified
200 --- 2.1.14 2006/03/14
202 Updated Windows package to include yazd.dll + yazd.lib for the
203 Development component.
205 If the environment variable YAZ_LOG is set, then it is used as a
206 string indicating the default level of logging to use if not
207 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
208 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
209 used as before. So, for example, to omit warnings from YAZ logging,
212 cql_transform() now map structure and other attributes before indexes,
213 so that index-specific structures and other attributes can override
214 defaults. So now a combination of mapping specifications such as:
216 index.dc.date = 1=date-modified 4=5
217 does the right thing.
219 cql_transform() now also respects the "always" mapping specification,
220 which establishes an initial set of attributes to be used for all
221 terms except where overridden by more specific attributes associated
222 with the index, relation or modifier.
224 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
225 which mode to use; one of "post", "get" or "soap" (SRW, default).
227 Fixes for yaz_iconv routines: changed trie-based character set conversions
228 to use only non-negative values for bit fields due to Sun's C compiler not
229 supporting negative values.
231 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
232 sequences where not read correctly. Fix by Rustam Usmanov.
234 Updated win/makefile to use options, settings which makes things
235 compile with VS C 2005.
237 --- 2.1.12 2006/02/01
239 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
241 In ZOOM socket code, use select instead of poll on MacOSX.
243 ZOOM-C now support client-side compilation of CQL into RPN that is
244 sent to the server, enabling CQL to be used against all Z39.50
245 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
246 ZOOM_query object, and submit it using ZOOM_connection_search().
247 The CQL-to-RPN translation uses a configuration file, the name of
248 which must be specified in the Connection's "cqlfile" option.
250 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
251 function, which takes as its start-term parameter a ZOOM_query object
252 (which may have had either CQL or RPN set into it).
255 --- 2.1.10 2005/11/29
257 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
258 GFS to support this as well. Backend handler, bend_srw_update, does the
259 update work. Code contributed by Ko van der Sloot.
261 Allow retrieval of Search Result-1 information in ZOOM by the use of
262 options that are attached to a result set. ZOOM documentation updated
265 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
266 UTF-8 conversion. Patch by Raj Patel.
268 Added option -m to GFS to control formatting of timestamps in log file.
270 Added 'exit' as synonym for 'quit' in yaz-client
272 Added support for specifying SRW resultSetId + resultSetIdleTime in a
273 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
274 for the new members. Patch by Ko van der Sloot.
276 Added support for SRU POST. It is supported for content-type
277 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
279 Do not build the separate Multi-threaded (MT) library libyazthread.la.
280 Instead make the library libyaz.la multi-threaded. Threading as a whole
281 can still be disabled by configure option --disable-threads. Previosly,
282 with older GLIBCs there were problems with MT libs under Apache. This
283 has now been fixed a long time ago.
285 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
288 CQL module modified to be case insensitive for relations/indexes/operations.
290 Fixed bug in CQL transform code: incorrect value relationModifieder
293 Added 'show all' command for yaz-client which retrieves all results
296 Added new yaz-client, xmles, which takes a (private) OID and
297 a document to be sent as an extended service request.
299 Describe new yaz-client commands wait_response and set_auto_wait.
301 Increase TCP/IP listener backlog from 3 (which I am guessing was
302 copied from the SunOS manual entry way back when) so SOMAXCONN, so
303 that the socket will queue as many incoming connections as it's able
304 to handle ongoing connections. In other words, it will never now
305 refuse a connection that it would be able to handle merely because
306 it's not got around to accepting() enough of the pending connections
307 yet. This is the behaviour anyway under Linux, where the listen()
308 argument is ignored; but not under BSD and on systems such as
309 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
310 YAZ-based servers should now be uniform across operating systems in
313 yaz-marcdump uses 64-bit file access on some systems. This is enabled
314 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
315 This allows yaz-marcdump to read large MARC batches (>2 GB).
317 Modified all YAZ source files - except the source which is auto-generated
318 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
321 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
322 corresponding to the existing *_setl() function. These allow option
323 values containing arbitrary valuues.
325 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
326 ZOOM_resultset_sort() in new applications. Its behaviour is identical
327 except that it returns an indicator of whether or not the sort
328 criterion was accepted (0 for OK, -1 for invalid).
332 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
333 MARC output rather than returning "new" buffer.
335 yaz-client warns about unknown init options.
337 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
341 Added support for SRW sort in Generic Frontend Server. Patch
342 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
343 sortKeys - or NULL if none is provided.
345 Fixed bug #307: It was impossible to specify indefinite/no timeout
346 for ZOOM_event. Special timeout value -1 now means indefinite timeout
349 Added support for multiple languages and charsets to be specified in
350 ZOOM. Each charset/language is separated by a blank. If negotiation is
351 in effect in init-response, Option
352 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
353 Code based on patch by Vasiliy Osadchuk.
355 Fixed bug #306: infinite recursion that occurred when calling
356 yaz_log_level_init as the first call (before other log level or
359 Fixed bug in scan handling in front end server: if preferred-Position-In-
360 Response was non-present, a NULL pointer referece was performed.
364 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
365 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
366 now defined for all those error codes. So instead of putting 109 in
367 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
368 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
370 Modified the yaz-marcdump utility to skip garbage bytes between MARC
373 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
375 Program yaz-client now exits and produces an error message if multiple
376 Z39.50 servers are specified on the command line (none or one allowed
379 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
384 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
386 Fixed bug #272: Preserve spacing for CCL terms.
390 Added support for virtual hosts and multiple backend servers for
391 the YAZ frontend server. The configution is XML based and
392 support specificition of CQL to RPN mappings and explain information.
393 See section "Virtual Hosts" in the YAZ manual.
395 Extended OPAC display utility. OPAC display utility renders
396 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
397 to supplement yaz_marc_decode_wrbuf.
399 Fixed a bug in MARC decoder that could caused it to crash for some
400 invalid MARC records. More diagnostics and warnings where added in
401 XML output (warnings, etc are stored in comments).
403 --- 2.0.34 2005/02/08
405 Fixes for UNIX domain sockets. Bug #261.
407 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
409 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
410 Added yaz_marc_subfield_str which defines subfield lead string which is
411 used in YAZ_MARC_LINE format. Default string is blank+$. Added
412 yaz_marc_endline_str which defines end of fields string used in
413 YAZ_MARC_LINE format. Default string is newline.
415 Experimental support for MarcXChange. This format can be produced
416 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
417 http://www.bs.dk/standards/MarcXchange.xsd
419 Added yaz-client commands scansize that sets maximum number of
420 entries to be returned by scan.
422 --- 2.0.32 2005/01/11
424 Added support for SRW scan in yaz-client and Generic Frontend Server.
426 * Added whereInList member to SRW Scan Term.
428 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
430 Fixed NMEM system to return aligned blocks on the smallest boundaries
431 that are suitably aligned for all possible types on the particular
432 architecture YAZ is being built for.
434 --- 2.0.30 2005/01/04
436 Fixed numerious warnings that was issued with newer versions of GCC.
438 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
439 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
442 Make YAZ Generic Frontend Server slightly faster.
444 Enhance (and reduce) logging for Generic Frontend Server.
446 Revert YAZ log system so that it flushes every write operation
447 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
449 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
450 instead of LOG_, due to name clash with syslog(3). LOG_ are still
451 present. New applications should define YAZ_USE_NEW_LOG=1 - this
452 will effectively disable old definitions.
454 --- 2.0.28 2004/11/09
456 Added yaz_log_time_format which specifies log format using
459 Added yaz_log_module_level which returns mask for a module. Value
460 is non-zero mask a if module is enabled; zero if disabled.
462 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
463 in include/yaz/cql.h.
465 Fixed bug #176: Dont throw diagnostics on empty SRU args.
467 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
469 Fixed bug #172: RPM builds does not enable SSL.
471 Doxyfile.in part of dist. Doxyfile generated by configure.
473 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
474 are given and the corresponding component does not exist.
476 Extend CCL documentation in YAZ reference. Describe r=r.
478 --- 2.0.26 2004/10/01
480 Fixed MARC->MARCXML conversion to properly deal with
481 fields, subfields, indicators having non-ASCII characters.
483 Fixed MARC->MARCXML conversion so that ASCII control characters
484 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
487 Added YAZ GFS support for conversion from Z39.50 surrogate
488 diagnostics to SRW surrogate diagnostics.
490 Bug fix: YAZ GFS did not return schema in explainResponse.
492 --- 2.0.25 2004/09/30
494 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
495 now converts recordSchema to elementSetName as well as schema URI.
497 Fixed bug in COMSTACK that prevented HTTP request packages from being
500 --- 2.0.24 2004/09/29
502 Added CCL facility r=r "range" which is similar to r=o "ordered" but
503 does not require white-space before and after the dash in a range, e.g.
504 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
507 Fixed a few AC_TRY_LINK configure tests that did not operate properly
508 due to new GCC removing "redundant" code.
510 Added yaz-client commands scanpos and scanstep that sets preferred
511 position and step-size for scan.
513 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
515 Added CCL utility ccl_qual_buf which parses one or more CCL
516 spec lines in a buffer.
518 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
519 of name and value - ignoring empty lines and comments.
521 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
523 Added odr_get_element_path which returns current element path for an
524 ODR handle. This utility is useful in error handling or user-defined
527 Added ODR_PRINT utility odr_set_stream which is is a more generic
528 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
529 to a write function and pointer to close function. The close function - if
530 non-NULL - will be called during odr_destroy.
532 Fixed bug in CCL parser where truncation char was not removed from
533 right side when truncation=both was in effect.
535 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
538 --- 2.0.23 2004/08/11
540 Fix buffer overrun in CQL parser when dealing with proximity (%).
542 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
543 to UTF-8/UCS conversion is now only based on codetables.xml.
545 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
547 --- 2.0.22 2004/08/06
549 Add support for more "commit changes" in ZOOM (uses Extended Services).
551 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
554 Yet another small fix for configure of SSL.
556 --- 2.0.21 2004/05/14
558 Fix SSL libs for configure when --with-openssl=DIR is given.
560 --- 2.0.20 2004/05/10
562 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
564 SSL comstack now uses yaz.pem certificate file on server side
565 by default. Certificate filename can be configured by calling
566 comstack function cs_set_ssl_certificate_file before cs_bind is used.
568 Fix bug regarding multiple calls to ZOOM_connection_connect.
570 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
572 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
573 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
575 ZOOM now allows inspection of X509 peer certificate for verification.
576 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
578 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
579 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
580 as "modular" but it simplifies things.
582 Added cs_get_peer_certificate to that returns peer X509 PEM.
584 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
585 NULL if SSL is unavailable.
587 Documentation about MARC decoding tools.
589 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
591 --- 2.0.19 2004/03/30
593 Rename CHANGELOG to NEWS to follow GNU style packing.
595 Fix bug with missing initialization of member in init_diagnostics.
596 This bug affects threaded version of GFS server.
598 --- 2.0.18 2004/03/20
600 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
603 Ensure zlib.dll is packed with Windows install.
605 --- 2.0.17 2004/03/17
607 Fix encoding of xsd:string to use text instead of CDATA.
609 Fix endless loop in CQL parser with unbalanced ".
611 Use a more compact way to store MARC-8 conversion tables.
613 --- 2.0.16 2004/03/16 Debian only
615 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
618 Update CQL parser to use new CQL 1.1 modifiers for booleans and
623 --- 2.0.15 2004/03/01
625 Another fix for decoding of XML packed records.
627 --- 2.0.14 2004/02/25
629 Fixes for Chunked encoding. White space not ignored after length spec.
631 Update NS and use default NS for SRW diagnostic elements.
633 --- 2.0.13 2004/02/23
635 Implement ZOOM_resultset_cache_reset which resets record cache.
637 Implement ZOOM_resultset_sort which sorts a result set.
639 Implement chunked HTTP transfer.
641 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
643 --- 2.0.12 2004/02/16
645 Added member 'schema' to bend_explain_rr structure so that backend
646 can specify explain record identifier. Defaults to Zeerex 2.0.
648 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
650 --- 2.0.11 2004/02/16
652 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
655 Added init command for yaz-client which sends "extra" init request.
657 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
658 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
660 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
662 Make ZOOM error code for "invalid query".
664 Fixed compilation for SSL which wasn't properly enabled for all platforms.
666 --- 2.0.10 2004/02/05
668 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
671 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
673 Added option -p <file> to make Generic Frontend Server to write PID file.
675 Added option -D to put Generic Frontend Server in background on its own.
677 Make ZOOM C recognize option "password". If unset, "pass" is used
678 (for backwards compatibility).
680 Fixed a bug in Generic Frontend Server that could make it crash if a
681 client sets characterSetNegotation bit, but didn't pass negotiation stuff
684 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
685 Must be issued before open, in order to be in effect.
687 --- 2.0.9-6 2004/01/12 Debian/Windows
689 Make the SRU server more picky WRT unknown params, etc.
691 Bug fix: ZOOM scan response didn't return displayTerm - when present.
693 New YAZ client command, options, that sets Z39.50 options.
695 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
696 options from a string of tokens (one token for each option bit).
698 Update SRW diagnostic code messages.
700 --- 2.0.9-5 2004/01/07 Debian/Windows
702 Handle user defined stylesheet for SRW/SRU.
704 --- 2.0.9-4 2004/01/06 Debian/Windows
706 Fix bug in decoding of Content-Length.
708 --- 2.0.9-3 2004/01/06 Debian/Windows
710 Fix a bug with decoding of XML packed records.
712 --- 2.0.9-2 2004/01/05 Debian only
714 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
716 Fix bug in SRW/SRU diagnostics decoding.
720 Fixed bug in Generic Frontend Server which could drop records exceeding
721 preferred message size. Reported and fixed by Irina Dijour.
723 Fixed calculation of package size for structured records in Generic
724 Frontend Server. Reported and fixed by Irina Dijour.
726 Fixed namespace for SRW/SRU diagnostics.
728 Fixed SEGV in yaz-client that occured for HTTP connection errors.
732 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
733 this version is incompatible with version 1.0 and older YAZ SRW/SRU
736 CQL changes to reflect recent changes to the specification:
737 * Documentation talks about context sets instead of index sets.
738 * Documentation talks about indexes instead of qualifiers.
739 * The CQL-to-PQF transformer's configuration file now uses
740 "index.set.name = <attributes>" instead of the old form
741 "qualifier.set.name = <attributes>". (Both forms are still
742 understood but the latter is deprecated.)
743 * CQL terms with no explicit index specified are now interpreted as
744 cql.serverChoice instead of srw.serverChoice (which of course
745 behaves exactly the same.)
749 MARC conversion can now generate ISO2709 output in another
750 character set. yaz-marcdump uses this facility if you invoke it
753 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
754 functions from there can be used from C++.
758 Frontend server now transfers memory from decoded packages to stream
761 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
762 references to show up.
764 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
765 the ZOOM Abstract API. The older names for the same options are still
766 also supported for the benefit of old applications.
768 ZOOM-C supports "implementationId" and "implementationVersion" options
769 to go along with "implementationName". These allow the user code to
770 specify identification strings to be sent to servers.
771 Add OID for the new ExtLite attribute set.
773 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
774 as requested/supplid by Ere Maijala <ere@atp.fi>
776 For generic frontend server, reverse the order of
777 "toolkit-supplied / application-supplied" strings sent as implementationId,
778 Name and Version. Also, remove the spaces around the slash. This brings
779 the GFS in line with the behaviour of ZOOM-C on the client side.
781 Add function ZOOM_scanset_display_term.
783 yaz-client shows scan displayTerm if present.
785 Utility yaz-iconv is now installed by default along with the man page
788 Extend configure check for OpenSSL to use pkg-config where available (such
791 Incorporate patch by Morten Bogeskov which allows a Unix file socket
792 server to specify uid/gid/mask for socket using the format
793 unix:[user=uid,][group=gid,][umask=mask,]file=path
794 If file= is omitted the existing format is assumed, e.g.
796 in which case the mask is 0666 (rw for everybody).
798 Major restructure of YAZ source. All source in libyaz is in src directory.
799 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
800 util (utility programs such as ASN.1 compiler, yaz-marcdump).
802 Added man page for utility yaz-marcdump (used to be called marcdump).
803 yaz-marcdump is installed by 'make install'.
805 Fixed a memory leak in Generic Frontend Server that occurred when decoding
806 of incoming package failed.
808 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
810 Change prototype of odr_perror: add const to message string.
812 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
814 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
815 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
816 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
817 DNS lookup. There should not be any compatibility problems with this
818 assuming that blocking=1 or 0 is used.
820 Fix bad reference in UNIX comstack in function cs_addrstr.
822 Fix for compilation on AIX.
824 The generic front-end server (server/seshigh.c) now supports returning
825 Init diagnostics to the client in User-information-field, in
826 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
831 Allow any CQL relation (not just all,any,exact,scr).
833 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
834 that features the same UI.
836 Implemented command update0 in YAZ client which is equivalent to
837 update but uses old of Ext Update ASN.1.
839 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
840 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
841 Previously no OID was used for this info.
843 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
844 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
845 returns 'malformed search term' otherwise.
847 SortResponse member resultCount now set to NULL in sort handler of
850 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
853 Add three new utility functions for translating OIDs between various
854 formats -- symbolic name such as "Usmarc", minus-1-terminated int
855 arrays and dotted strings such as "1.2.840.10003.9.5.1":
856 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
857 char *oid_to_dotstring(const int *oid, char *oidbuf);
858 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
860 Reverted modifications for ES Update definition for z_IU0Update
861 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
862 is back to YAZ 2.0.2.
864 String value attributes for CCL parser.
866 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
867 which their FirstSearch server returns in Init responses, sometimes
868 carrying useful diagnostic information when Init fails. This has the
869 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
870 "z39.50/oclcui.asn", where its definition is somewhat different from
871 what OCLC document on their web-site, as required to interoperate with
874 Support for anonymous authentication in yaz-client. Use the command
877 * Fix the OID of the Index Data-local "admin" Extended Service from
878 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
879 the 1000, which indicates a locally-defined OID, was a mistake.
883 Fix CCL directive @case handling so that it affects string match for
884 both CCL keywords and qualifiers.
886 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
887 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
888 Decoder has been updated with ASN.1 changes as listed in
889 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
890 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
891 z_IUUpdate, remains unchanged.
893 ZOOM_record_get may now return a record in a specific character set.
894 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
895 "from" is the character set of record as returned by target. "to" is
896 the character set to be returned. If omitted, "to" is UTF-8.
898 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
900 New ODR utility, odr_getelement, which returns name of element for
901 which encoding/decoding failed.
903 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
904 in cases where a required element was omitted.
906 Bug fix: some MARC8 sequences were not converted.
908 New ZOOM option "step" which specifies number of records to be
909 retrieved in one chunk. Used in conjunction with "start" and "count".
911 SRW support for yaz-client. Use scheme http: to use it, e.g.
914 yaz-client no longer does (un)intelligent character set conversions
915 by default. Can be enabled with charset and marc_charset commands.
917 xmalloc trace fix for 64-bit systems such as DEC alpha.
919 Solaris 2.6 compile fix.
921 New function, cql_strerror() translates SRW error codes, as returned
922 by cql_transform_error(), into human-readable English strings. Used
923 in yaz-client diagnostics when appropriate.
925 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
926 converts it into a type-1 query which is sent to the server. This
927 makes CQL available for use with all Z-servers, as opposed to the tiny
928 minority that can handle CQL queries themselves.
932 New Debian package layout similar to the Redhat Package layout.
934 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
935 and search result respectively.
939 Redhat package is now several packages: libyaz (runtime libraries),
940 libyaz-devel (development and documentation, and yaz (utility programs).
941 Package spec file by Morten Bøgeskov.
943 New member 'schema' in struct bend_fetch_rr which the name of requested
944 schema (SRW/SRU) for record (or NULL if none was given). The fetch
945 handler MAY set this to reflect the schema of the returned record.
947 New member 'display_term' in struct scan_entry. GFS now sets member entries
948 and allocates scan entries to be filled by user scan handler. In previous
949 version, entries member was allocated by the scan handler. That still works,
950 but the GFS will ignore member display_term - assuming it was NOT set by
951 the handler. The fact that the GFS now allocates the entries both allows
952 for new members and makes a scan handler easier to write.
954 Fix CQL lex buffer overflow.
956 SRW/SRU recordPacking. For SRW default recordPacking is string. For
957 SRU default recordPacking is string.
959 SRU protocol support for frontend server.
961 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
963 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
965 Added scan for the ZOOM shell (zoomsh).
969 * String Identifers for Schemas (Amendment 5).
970 http://lcweb.loc.gov/z3950/agency/amend/am5.html
971 Old definition for schema
972 Odr_oid *schema; /* OPT */
977 Z_InternationalString *uri;
978 #define Z_Schema_oid 1
979 #define Z_Schema_uri 2
982 * resultCount parameter to Sort Response (Amendment 1).
983 http://lcweb.loc.gov/z3950/agency/amend/am1.html
985 Support for SRW 1.0 over HTTP. This is an optional feature and
986 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
989 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
990 on the same port. SRW SearchRetrieveRequests are mapped
991 to bend_init,bend_search,bend_fetch,bend_close.
993 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
995 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
996 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
998 ZOOM connections are SRW based if schem http is used for hostname
999 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1000 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1002 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1003 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1004 distance=n, order=true/false, relation=le, prox unit=word. If
1005 n is omitted, distance 1 is used.
1007 Fixed problem with C compiler include path in wrong order.
1009 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1010 on Solaris. Patch from Ko van der Sloot.
1012 New MARC decode API. All new functions operate on a yaz_marc_t
1013 handle. The most important new functions are: yaz_marc_create,
1014 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1015 decode and destroy respectively. Decoder can produce formats
1016 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1017 include/yaz/marcdisp.h.
1019 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1020 to UTF-8, UCS-32, wchar_t or Latin-1.
1022 * Prototypes for yaz_iconv_-functions moved to separate header
1023 include/yaz/yaz-iconv.h.
1025 Make a few private functions 'static' in unix.c. This prevents
1026 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1028 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1029 are set when Init Response is received.
1031 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1032 but returns diagnostic set as well.
1034 New function yaz_strerror which is a portable wrapper for
1035 strerror/strerror_r/GetLastMessage.
1037 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1038 is returned for MARC. If type is "oai", then OAI MARC is returned.
1040 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1043 --- 1.9.2 2002/11/26
1045 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1047 Fix bad race conditions on SIGTERM and terminate gracefully in
1050 Move retrieval (data1) module to Zebra since nobody seems to be
1053 Add GRS-1 render for ZOOM using same format as yaz-client.
1055 --- 1.9.1 2002/10/05
1057 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1059 Fix broken ESpec handling in data1 module.
1061 SGML reader parses comments and makes them part of the data1 tree.
1063 Added several type casts so that YAZ compiles as C++ code.
1065 ZOOM didn't handle PDU encoding failures properly.
1067 Added more Bib-1 diagnostics (approved extensions).
1069 GNU configure: better check for iconv.
1071 More portable use of accept, getpeername. Check for socklen_t. Use
1072 int/size_t if socklen_t is not defined.
1076 PQF parser rejects bad queries - including those with extra
1077 characters in them. PQF parser used to silently ignore that.
1078 Cleaner API for PQF added, which allows you to get detailed
1079 error information for bad queries (see yaz/pquery.h).
1081 Fixed bug in ZOOM_record_get for type "database".
1083 Implemented mini iconv library supporting conversions between
1084 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1086 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1088 --- 1.8.9 2002/08/20
1090 Fixed ZOOM C record cache so that preferredRecordSyntax and
1091 elementSetName is used to check for already fetched records.
1093 --- 1.8.8 2002/08/02
1095 Added three members in bend_initrequest structure to facilitate
1096 character set negotiation.
1098 Fixed a bug in frontend server that could cause indefinite
1099 loops under rare conditions.
1101 Revised character set utilities (charneg.h) so that encoding
1102 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1104 For PQF, directive @term <type> sets term type for Scan/Search.
1105 Here <type> is general, string, numeric, null. The term type
1106 is inherited - just like @attr.
1108 New call odr_set_charset that sets character set conversion for
1109 international-strings on a ODR stream. Prototype is:
1110 int odr_set_charset(ODR o, const char *to, const char *from);
1111 The InternationalString is still represented as C string in YAZ
1112 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1113 won't). On the protocol level, you can use any encoding.
1115 Support for UNIX sockets in ZOOM.
1117 Solaris recv sometimes returns errno == ENOENT. It is treated as
1118 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1120 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1121 both client and server. Code by Morten Bøgeskov.
1123 --- 1.8.7 2002/05/22
1125 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1126 that they can be used directly from Visual Basic. You must recompile
1127 your windows APP if you're using ZOOM.
1129 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1130 Commands "lang" and "charset" sets language and character set respectively.
1131 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1132 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1134 Attributes from multiple CCL fields may be OR'ed rather than merged
1135 using directive "@field or". Fields are still merged by default -
1136 equivalent to "@field merge".
1138 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1141 Fixed bug in zget for parameter ExtendedServicesResponse.
1145 --- 1.8.6 2002/03/25
1147 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1149 Client displays USR.1:SearchResult-1 (hits per term).
1151 Additional Search Info for search in Generic Frontend Server.
1153 Fixed CCL parsing of "field=s".
1155 WIN32 installer - using the excellent NSIS software from nullsoft.
1157 Fixed CCL parsing of "field = - <number>".
1159 Added function yaz_marc_decode that decodes MARC for line mode
1160 display or XML (similar to that used by JZKit).
1162 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1163 Z39.50. But ISO/ILL was, however.
1165 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1166 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1168 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1169 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1171 --- 1.8.5 2002/02/03
1173 New YAZ client features: Command completion and new commands:
1174 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1175 Code provided by Jacob Poulsen.
1177 New call oid_trav, that visits all registered OIDs via callback.
1179 Function ZOOM_record_get now returns const char pointer rather than
1180 void pointer. It saves a lot of type casts.
1182 For YAZ client, command "auth" now allows you to set authentication
1183 in IdPass style. It is enabled when three tokens are given - order
1184 is user, group and password.
1186 Fix memory leaks in MARC record handling for ZOOM.
1188 New option for YAZ client, -k <kilobytes> that sets
1189 maximum record size. Similar to -k option for generic frontend
1190 server and yaz-ztest.
1192 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1194 Prefix query parser reports "fail" when bad attribute set is given.
1196 Fix in MARC decoder. Proximity logging. Fix for attribute set
1197 in scan handler for server. Patches by Shigeru Ishida.
1199 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1202 Configure option --with-openssl=<dir> now works when a directory is
1203 specified. Patch provided by Morten Bøgeskov.
1205 New option for YAZ client, -u <auth>, that sets authentication.
1207 ZOOM fix: error information was sometimes "missing", since error
1208 was cleared/reset too when it shouldn't.
1210 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1212 --- 1.8.4 2002/01/04
1214 Scan for ZOOM API. New object ZOOM_scanset. New functions
1215 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1216 ZOOM_scanset_destroy.
1218 New ZOOM function, ZOOM_connection_last_event, that returns type
1219 of last event (such as "receive data", "send data", "apdu received",
1222 New ZOOM option, schema, that specifies schema for retrieval.
1224 New CCL feature. Qualifiers can be aliases for one or more
1225 other qualifiers (if more than one is given, OR is used).
1227 ZOOM uses named result sets if target supports it.
1229 Two new YAZ client commands: . (dot, which sources a script of YAZ
1230 client commands), and ! (to execute shell command.). Implemented
1233 Working on Debian packages.
1235 --- 1.8.3 2001/11/19
1237 YAZ client enables named result sets only if target supports it.
1239 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1241 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1242 with key="host" to get same result.
1244 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1245 Function Z3950_resultset_record(s) returns references to records
1246 "owned" by resultset. To become owner use Z3950_record_clone.
1248 Function z_ext_record handles Extended Services. Thanks to
1251 --- 1.8.2 2001/11/12
1253 CCL Parser fix: ignore token comma when dealing with and-lists.
1255 Documentation updates for COMSTACK.
1257 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1258 Changed prototype Z3950_records. For some functions, int parameters
1259 were changed to size_t.
1261 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1264 New MARC decode/display function, marc_display_exl, which properly rejects
1265 non-ISO2709 records. YAZ client uses it.
1267 --- 1.8.1 2001/10/29
1269 Fix bug: local attribute set wasn't set correctly in PQF strings.
1273 * Old Z39.50 codecs no longer supported.
1275 Added ZOOM C binding. See http://zoom.z3950.org/
1277 Renamed states for COMSTACKs to avoid confusion with events.
1279 Implemented cs_look and proper cs_rcvconnect.
1281 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1283 Configure detects POSIX threads on OpenBSD.
1285 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1286 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1288 When error is returned from present handler, non-surrogate diagnostic
1289 is returned in present response (and fetch handler is no longer called).
1291 * Minor adjustments to pquery parser (PQF). Token characters may be
1292 escaped by using backslash (C-style).
1294 PQF parser allows string attribute values to be specified. For @attr,
1295 non-numeric characters after the equal-sign are treated as strings
1296 (e.g. @attr 9=title).
1298 CCL trunction character may be defined (@truncation in file)
1300 * function zget_ExtendedServicesRequest sets waitAction to
1301 waitIfPossible (was wait).
1303 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1306 CCL operator names may be set in field definition files (CCL_bibset).
1307 See ccl/bib1 for an example.
1309 Fixes in ASN.1 compiler for C++ compatibility.
1311 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1312 and "op_or" to avoid conflict with C++.
1314 Fixed problem with GNU readline detection on Redhat 7.0.
1316 Added step-size for Scan backend handler.
1318 Fixed bug that made the frontend server crash when no attribute
1319 set was specified for scan.
1321 Front-end server automatically switches to original working directory
1322 when installed as an NT service. Previously -w had to be specified to
1325 Added extended attributes for retrieval module (data1), so that data1
1326 records carry d1_readXML/SGML attributes. d1_read also supports
1327 null-data rules ( <tag/>)
1329 On UNIX when POSIX threads are available, a separate library libyazthread
1330 is created. Programmers should link with that library and the yaz library
1331 when using threads. The reason for the split was that some applications
1332 on Linux, such as Apache, doesn't work well when using shared objects that
1335 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1336 (or any frontend server) in SSL mode by specifying ssl: followed by
1337 address. Only tested on UNIX.
1339 Added feature for CCL module. Virtual structure s=al or s=ol generates
1340 and-list and or-list respectively instead of phrase search.
1344 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1345 log_mask_str. This was done to avoid name conflicts with other libraries
1346 (such as other PHP extensions).
1348 Added raw OID member for preferred record syntax (request_format_raw)
1349 and returned record syntax (output_format_raw) for backend fetch method.
1351 Config file yaz-config now accepts options so that it returns specific
1352 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1354 Shared library support for UNIX using GNU libtool.
1356 * Modified backend interface. Request/Response struct's replaced by
1357 one read/write C struct. For example bend_fetchrequest and
1358 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1359 Every handler - even search has to be registered in bend_init
1360 handler. This means that the YAZ library no longer refers to
1361 external functions and it makes it possible to make the whole
1362 thing a single DLL/SO.
1364 Added Segment handler for backend server.
1366 Added Zmbol/Zebra administrative functions to YAZ client.
1368 Threaded frontend server on UNIX (when POSIX Threads are available).
1369 Starting the server with option -T enables multi-threading.
1373 Added configure option --enable-comp/disable-comp to control use
1374 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1375 located in sub directory asn.
1377 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1378 in ${exec_prefix}/bin along with the other programs yaz-client and
1381 GNU automake used to maintain makefiles.
1383 Added several OID's.
1385 Changed retrieval module so that we can load records with no abstract
1386 syntax defined. Tagpaths in these records are fully composed of string
1389 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1393 On UNIX, the generated makefile now supports a proper 'make install'.
1394 The prefix can be set via GNU configure to set the install location
1395 (default is /usr/local).
1397 * YAZ programs client and ztest were renamed to yaz-client and
1398 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1399 locations, such as /usr/bin,/usr/local/bin,etc.
1401 * YAZ Header files were moved from include to include/yaz. YAZ Header
1402 files are referred to as include <yaz/log.h> rather than <log.h>.
1403 The YAZ include path (-I ..) is therefore the same as before. Programmers
1404 should update their #include statements or use -Ipath/include/yaz
1405 instead. The main motivation for doing this change is that YAZ header files
1406 can be installed in "standard" locations /usr/include,/usr/local/include
1407 without introducing conflicts, since ALL YAZ header files are stored
1408 in subdirectory yaz (under /usr/include for example).
1410 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1411 rather than project/workspace files. We switched because project files
1412 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1415 Changed name of logging function, logf, to yaz_log, to prevent name
1416 clash with some math-log functions. The YAZ header log.h defines logf
1417 to yaz_log (#define) so there should be no incompatibilities by this
1420 Added bend_start/bend_stop handlers for server. These handler are
1421 called on start/stop of server. For windows they are called whenever
1422 a service is started/stopped.
1424 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1425 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1426 in util/yc.tcl. The auto-generated C code structures are, in a few
1427 cases, incompatible with the old decoders. There are differences in the
1428 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1429 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1430 The preprocessor variable ASN_COMPILED is defined when the compiled
1431 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1432 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1433 wish to use the old encoders/decoders you can specify --disable-yc
1436 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1437 version so that it supports both new - and old version of DB Update
1439 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1440 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1441 change. The name parameter can be set to 0 in which no name is specified
1442 for the construction. The macros odr_implicit and odr_explicit sets name
1443 parameter to zero for the construction involved. New macros
1444 odr_implicit_tag and odr_explicit_tag are similar to the others,
1445 except that a name parameter is added. For programmers' that don't use
1446 ODR they probably only need to change the call to z_APDU and z_External.
1448 Added access control facility by interfacing the TCP wrapper library.
1449 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1450 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1451 name of the daemon and enables the access control as specified in
1452 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1454 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1455 den Dool <H.M.vdnDool@kub.nl>.
1457 Added reference ID parameter to most functions in server API - refer
1458 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1460 Changed name of ccl library to libccl.a (was ccl.a).
1462 Fixed bug in decoder for Explain (Category TargetInfo).
1464 Added support for GNU readline in client. Thanks to Jacob Poulsen
1465 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1467 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1468 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1469 IMPLEMENTATION! This change was made to the development version before
1470 the ZIG decided to retract the amendment. If any users MUST be
1471 compatible with the original Update definition, PLEASE CONTACT US, and
1472 we will include a separate definition corresponding to the old Update
1473 ES. Note that because of the change to the ASN.1 of the
1474 TaskPackageRecordStructure we cannot define a single structure that
1475 will support both versions.
1477 * Added const modifier to buffer parameter for some ODR/BER encoding
1478 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1479 completeWAIS, odr_dumpBER.
1481 Fixed bug in client.c which caused a crash when a scanResponse didn't
1482 contain positionOfTerm.
1484 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1485 * will cause an error in a client if a non-YAZ target sends both a
1486 * list of Scan entries and non-surrogate diagnostics.
1488 Retrieval module enhancements. Tag sets may be typed in the reference
1489 to it. From the .abs-file the "tagset" directive takes a third optional
1490 integer type for the tag set referenced. From a .tag-file the "include"
1491 directive takes a third optional type as well. The old "type" directive
1492 in the tag set itself is still recognized but acts as the default type
1495 Backend interface change. Individual Scan terms returned from bend_scan
1496 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1497 in include/backend.h.
1499 Retrieval module enhancements. Multiple tag sets and attribute sets may
1500 be specified in abstract syntax specs. Revised the error/warning for
1501 logging messages reported by the retrieval module when reading the
1504 Object Identifier system (oid_..) changed. The API is backwards
1505 compatible but the oid-routines now allocates new OID's when needed.
1506 Raw OID's may be specified in oid_getvalbyname.
1508 YAZ now uses GNU configure to generate Makefile(s).
1510 * Minor changes in some of the member names of DeleteResultSetRequest and
1511 DeleteResultSetResponse. See include/proto.h.
1513 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1514 and added member 'languages' in TargetInfo (which was missing).
1516 Changed the way attribute sets are handled in the retrieval
1517 module. These are now cached, just like the abstract syntaxes
1520 Changed YAZ so that it links with compiled ASN.1.
1522 Added Explain-schema definitions and mapping routines. The following
1523 Explain categories have been implemented: AttributeDetails,
1524 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1526 Fixed minor bug in Windows version of Server Library.
1528 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1530 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1532 Added EXTERNAL: UNIverse Resource Report (non-standard).
1534 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1535 ENUMERATED and SET OF.
1537 * Added 'const' to some of the char pointer arguments for the
1538 functions, data1_read_node, data1_getelementbytagname,
1539 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1542 Fixed bug in data1_insert_taggeddata - the last_child member of
1543 parent wasn't initialised.
1545 * Changed data1_read_record and data1_read_node so that the supplied
1546 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1547 doesn't refer to any parts of the "SGML"-buffer.
1549 Fixed bug in server library (Windows version of statserv_remove).
1551 * Changed code so that it compiles as C++. The type definition
1552 of Odr_fun which is a member of Odr_arm was changed. The result is,
1553 that an explicit typecast is needed for the fun pointer when
1554 using Odr_arm - as in:
1555 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1557 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1559 Implemented the new structured date and time definition as approved
1560 by the ZIG. Added schemaId element to the specificTag in Espec-1
1561 (also approved at the last ZIG). Thanks to RVDM.
1563 Added some Object identifiers (RVDM).
1565 Changed the Update Extended Service (RVDM).
1567 Added command "refid" to client which specifies referenceId for
1568 the following requests.
1570 Implemented extended service handling for server. See ztest.c
1571 for an example as well as backend.h. New handlers are registerd
1572 in the Init handler.
1574 * Changed interface for sort in server.
1576 Added new members to statserv_options_block. It allows a server
1577 to read options from another source than just the command line. Thanks
1578 to Charles Woodfield.
1580 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1581 renamed to zboolean. Some C++ compilers complained about the name.
1583 Minor changes to gils.abs. Added index 's' (sort) on title
1584 and date/time-last-modified.
1586 --- 1.4pl2 1998/1/30
1588 Fixed bug in server library regarding inetd mode (-i). This bug
1589 was introduced by release 1.4.
1591 --- 1.4pl1 1998/1/29
1593 Added sort facility in client and backend server interface.
1595 Fixed problem with dependencies in Makefile(s).
1597 Fixed bugs for encoders/decoders of extended services and
1600 Implemented sub-tree feature for schemas. Sub-trees are
1601 referenced in *.abs-files. See explain.abs for an example
1602 of the use of this feature.
1604 Modified bib1.att; local attributes for ANY didn't include
1605 ANY itself (only affects use of the retrieval module).
1607 Fixed bug in plain SGML reader in function data1_read_node:
1608 tags with prefix "var" was incorrectly interpreted as variants.
1610 Added feature "sub-schemas" to enable references to - and definitions
1611 of - group of elements.
1613 * Removed member parent from type data1_element (in data1.h).
1615 Implemented function odr_nullval() that returns the value of
1618 * Removed member num_children from data1_node (in data1.h).
1620 Made NT service interface part of the server library. The
1621 function statserv_main uses the NT service when required and
1622 calls the statserv_start / statserv_close routines.
1624 Routine zget_SearchRequest and zget_PresentRequest fills
1625 resultSetName/Id member with "default" instead of "Default".
1627 Fixed memory leak in server. Request queue member wasn't freed.
1629 Fixed nmem_exit so that memory is freed.
1633 Revised the CCL parser utility to be thread safe.
1635 Added function, oid_ent_to_oid, to replace the function
1636 oid_getoidbyent, which is not thread safe.
1638 * Added nmem_init and nmem_exit to initialize and release
1639 NMEM resources. Function nmem_init should be called once in the
1640 initial thread before NMEM/ODR is used. statserv.c and client.c
1641 have been changed accordingly. The change was necessary to make
1642 NMEM thread safe. The NMEM memory pool is shared amongst threads
1643 in a process. Unix-based applications will still work fine without
1646 Added NT Services interface for the the Z39.50 (statserv) Server.
1647 Refer to the ztest.c source on the usage.
1649 Windows 95/NT port using MSVC5.0. Project files are included in the
1652 * Defined new 'global' handle for the retrieval (data1) system. The
1653 new handled, data1_handle, describes the state of the data1 system.
1654 This handle is passed as first argument to virtually all
1655 data1 related routines. The functions data1_create and data1_destroy
1656 creates and destroys a data1 handle respectively.
1658 Added ODR encode stream member to all backend request structures
1659 init, search, scan etc. This stream should be used to allocate all
1660 memory used for the response when thread safe operation is needed.
1662 Changed the comstack utility, cs_addstr, to be thread safe. The
1663 returned hostname string returned by the function is now part the
1666 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1667 function. The cs_straddr takes a COMSTACK handle as argument, so this
1668 function must be used after cs_create and before bind/connect.
1669 This function is thread safe.
1671 Moved test server to 'ztest' directory - generic server code still
1672 in 'server' directory.
1674 Made prefix query (pquery.c) utility thread safe.
1676 Added new function modifier YAZ_EXPORT to 'export' public DLL
1677 functions when using windows (see include/yconfig.h).
1679 Added definitions to the OID database (util/oid.c) (RVDM).
1681 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1683 Added call to ccl_rpn_delete in client program.
1685 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1686 release of RPN structure.
1688 Added support for C++, headers uses extern "C" for public definitions.
1689 With input from RVDM.
1691 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1692 Thanks to Ronald van der Meer (RVDM).
1694 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1696 Added support for private extensions to the OID database
1697 (oid_setprivateoids()). Thanks to RVDM.
1699 Added optional, physical ANY (key replication)
1701 Fixed null-reference problem in GRS-1 output filter.
1703 Proximity operator added to Prefix Query Format (PQF).
1705 In test client command "base" accepts multiple databases.
1707 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1711 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1713 Smallish bug-fixes in the new encoders/decoders (explain).
1715 Bug fixed in DeleteRequest.
1717 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1719 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1721 Added SOIF syntax (using private OID for now) to retrieval module and client.
1723 Added Update extended service.
1725 Added SearchResult-1 additional info structure.
1727 Added optional CCL (ISO8777) interpreter as separate module. Available
1730 --- 1.2 1996/6/10 (1st anniversary release)
1732 Added Summary record syntax. Lightly tested.
1734 Added OPAC record syntax. Untested.
1736 Added ResourceReport service encoders/decoders. Untested.
1738 Fixed bug in z_Unit - wrong tagging on unitSystem.
1740 Fixed bug in the DiagRecs decoder.
1742 Added options for max PDU size and session timeout to frontend-server.
1744 Added documentation of query-language parsers and other supporting utilities.
1746 [frontend-server] Added Attribute set to the bend_scanrequest API.
1748 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1749 surrogate diagnostics were generated.
1751 [retrieval] Allow multiple local values for attribute.
1753 [retrieval] Allow multiple attributes per element in .abs files. index type.
1755 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1757 --- 1.1pl2 1996/4/10
1759 Minor changes, mostly specific to Zebra's requirements (retrieval)
1763 Repaired bug in frontend server when running multiple listening
1764 endpoints in dynamic mode.
1766 z_External() now won't break if a known, ASN.1 value comes encapsulated
1767 in an octet-string. The value will pass through unmodified in an Odr_oct.
1769 Added a bit of code to the demo client to decode & display
1770 ASN.1-structured records represented in the octet-aligned branch of
1771 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1773 Added z_ext_getentbyref() to the ASN module. Doc updated.
1775 * Completed the SCAN definition in the ASN module. This may break SCAN
1776 code based on older YAZ-versions at compile-time. The fix is easy -
1779 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1780 under the SCAN definition. Remember to initialize this, server-people.
1782 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1783 that this does not extend to ODR and ASN.
1785 Comstack allows insertion of established socket (primarily for
1786 inetd-operation of servers). Doc updated.
1788 Front-end server can now start from the inetd in TCP mode. Doc
1791 --- 1.0pl4 1996/1/24
1795 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1796 the rank and record number.
1798 Adjustments to the frontend server.
1800 Fixed diagnostic BER dumper. It ignored the file argument.
1804 Various changes to retrieval module.
1806 Changed the union discriminators of the protocol files from enums to
1807 ints paired with #defines.
1809 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1812 *Changed operator in the RPN structure to 'roperator', again to avoid a
1815 Fixed problems in Explain decoders/encoders.
1817 --- 1.0pl2 1995/12/6
1819 Memory bug in log module fixed.
1821 --- 1.0pl1 1995/12/5
1823 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1825 Bug in Explain DatabaseInfo module fixed.
1827 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1831 The shift to v1.0 signals that we now consider the *core* functionality
1832 of YAZ reasonably stable (the core being more or less equivalent to
1833 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1834 tested (Explain not at all - though that will happen soonish).
1836 Minor changes to code to support Windows port.
1838 Various minor changes after we're getting to use GRS-1 & co. more.
1840 Added Espec-1 format.
1842 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1843 of the protocol and it cannot be selected when encoding (maps into 'string'
1844 when decoding). Needed to talk to some servers.
1846 Demo client can request simple element set names.
1848 Added Diagnostic Format encoders/decoders.
1850 Added simple Close handling to frontend server (no hooks for resource
1851 reporting yet), and demonstration client.
1853 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1855 --- 1.0b3 1995/08/24
1857 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1858 handled incorrectly when records were requested in the searchResponse. This
1859 will only affect you if you use the frontend-server.
1861 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1862 Test-client will ask for and print GRS1. Ztest will return dummy records
1865 Added Explain encoders/decoders to the service-level API. Untested.
1867 Added Extended Services: Item Order encoders and decoders to the Service-
1868 level API. Untested. We could use a recent copy of the pertinent bits
1869 of the ILL protocol to add those bits.
1871 Added diagnostic format 1 encoders/decoders to the service-level API.
1874 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1875 odr_cons.c, which causes a more correct output.
1877 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1878 was always set to 0 when no records were requested in the searchRequest.
1880 * Added better external-handling. This shouldn't harm old code that
1881 *encodes* externals. It can break code that looks for a
1882 'single-ASN1-type' representation, since those types that are known
1883 are now decoded immediately. Look at the SUTRS sample code in
1884 seshigh.c and client.c. Documentation updated.
1886 Handling of structured records in bend_fetchresponse. Length -1 marks
1887 structured record, type is deduced from format field.
1889 --- 1.0b2 1995/06/27
1890 Fairly quick maintenance release to add SUTRS support.
1892 Fixed handling of SUTRS records in the demonstration client.
1894 * Added format field to the bend_fetchrequest and bend_fetchresponce
1895 structures of the backend API (frontend server). When the record is
1896 returned, the value of the format field is mapped to an OID. The
1897 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1898 of the record. The special value VAL_NONE in the bend_request means
1899 that no specific format was requested by the client. Documentation
1900 updated accordingly. Test server (ztest) will return a fixed dummy
1901 SUTRS record if your client requests SUTRS.
1903 Documentation updated accordingly.
1905 You can now set external libraries and RANLIB support in the top-level
1909 First public release.
