3 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
7 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
10 Fixed bug in Generic Frontend Server that could cause a server to stop
11 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
13 For the generic frontend server, the maximum record size is used as maximum
14 size of incoming packages (SRU + Z39.50). The value until was previously
15 only used in Z39.50 Init negotiation and, later, in a session controlled
16 sizes of records returned. This is controlled using -k option. It can be
17 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
21 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
24 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
26 New option for yaz-marcdump -lpos=value which allows setting a portion
27 of MARC header to a certain value.
29 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
31 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
32 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
36 Fixed problem with SRU mode type (soap, get, post) for yaz-client
39 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
43 Fixed MARC ISO2709 encoding routines to deal with character set
46 Minor changes to GFS logging. Database included in search request log
49 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
50 cached/multiple records.
52 Shared libraries are built by default on Unix+configure.
54 Changed cql2pqf transformation to use a different evaluation order. The
55 new order is: always, relation, structure, position, truncation, index
56 and relationModifier. Old order was: always, relation, relationModifier,
57 structure, index, position, truncation. Note that the the latter ones
58 override former ones for identical attributes.. The new scheme means that
59 it is possible to override any existing attribute with a relationModifier.
60 And also that it is possible to override everything for the index rule
61 (except the ones listed in relationModifier). No order is perfect but this
62 one, we believe, covers more real cases.. The "always" should have been
63 called "default", since the attributes there can be overridden with all
66 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
67 compilation phase, but also for yaz-config --cflags output. This allows
68 us to have public headers with Libxml2 stuff in them . It should also,
69 eventually, make Libxml2 checks redundant in packages using YAZ, such
74 Changed SRU update structure bend_update_rr so that SRU diagnostics are
75 stored in uri, message and details.. Previously diagnostics were stored
76 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
77 compatibility.. but he's probably the only one affected, so.
79 Added support for CCL, compiled on the client side, in ZOOM-C. This
80 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
81 input; the resulting query objects can be used for for searching with
82 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
84 YAZ' configure searches for OpenSSL by default.
86 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
87 SL_CTX_use_certificate_file. See
88 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
89 for more info. Thanks to Ko van der Sloot.
93 Bug #600: SRU GET, POST support for yaz-client. Introduced
94 command 'sru' which selects method SOAP/GET/POST.
96 Allow missingValueAction to be specified for the sortspec string -
97 function yaz_sort_spec. By default, the missing value action is null.
98 Use ! to specify "abort". Use = followed by stringvalue to specify default
101 Ensured that Present-handler (if defined) is called in GFS before any call to
102 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
103 searchRetrieve requests.
105 Documentation for YAZ is now based on the Docbook XML/XSLT using
106 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
107 is no longer depending on jade/openjade or docbook-to-man scripts.
108 PDF is no longer part of the distribution - but can optionally be
109 made using DSSSL/jadetex or FOP.
111 Added retrieval handling support in Generic Frontend Server to support
112 conversion between MARC/XML as well as XSLTtransforms. See
113 etc/yazgfs.xml for an example.
115 Added Authentication support to Generic Frontend Server in SRU
116 mode. Authentication using HTTP Basic is supported, as is the use
117 of 'x-username' and 'x-password' parameters in the request itself.
119 Added support for a new character set MARC8s identical to MARC8 except
120 that it converts combined characters to single Unicode characters in the
121 Latin-1 range (when possible).
123 --- 2.1.18 2006/04/24
125 ASN.1 compiler 0.4: generates brief Doxygen file header for
126 generated .h/.c files.
128 Utility yaz_iconv now supports conversion to MARC-8.
130 New facilities for the MARC module. The reading - and writing of
131 content are separate methods for the yaz_marc_t handle. The following
132 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
133 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
134 format). Write functions have prefix yaz_marc_write_.. The existing
135 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
136 available. Removed support for OAI-MARC and simplexml (not the
137 simplexml from PHP5).
139 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
140 to be returned for this connection.
142 --- 2.1.16 2006/03/31
144 Allow multiple languages and charsets to be specified with
145 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
146 negcharset iso-8859-1,utf-8
148 Translation of proximity nodes from CQL into PQF now works.
150 Moved to automake 1.8, 1.9.
152 Added function yaz_log_set_handler which allows a log handler to be
153 installed. This handler will be called for all log messages. Output
154 to file is also produced; but that can be disabled by passing NULL
155 fname to yaz_log_init_file.
157 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
159 For SRW (including GFS), accept application/soap+xml as content-type
162 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
163 produces NO stylesheet reference even if a default stylesheet is specified
166 --- 2.1.14 2006/03/14
168 Updated Windows package to include yazd.dll + yazd.lib for the
169 Development component.
171 If the environment variable YAZ_LOG is set, then it is used as a
172 string indicating the default level of logging to use if not
173 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
174 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
175 used as before. So, for example, to omit warnings from YAZ logging,
178 cql_transform() now map structure and other attributes before indexes,
179 so that index-specific structures and other attributes can override
180 defaults. So now a combination of mapping specifications such as:
182 index.dc.date = 1=date-modified 4=5
183 does the right thing.
185 cql_transform() now also respects the "always" mapping specification,
186 which establishes an initial set of attributes to be used for all
187 terms except where overridden by more specific attributes associated
188 with the index, relation or modifier.
190 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
191 which mode to use; one of "post", "get" or "soap" (SRW, default).
193 Fixes for yaz_iconv routines: changed trie-based character set conversions
194 to use only non-negative values for bit fields due to Sun's C compiler not
195 supporting negative values.
197 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
198 sequences where not read correctly. Fix by Rustam Usmanov.
200 Updated win/makefile to use options, settings which makes things
201 compile with VS C 2005.
203 --- 2.1.12 2006/02/01
205 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
207 In ZOOM socket code, use select instead of poll on MacOSX.
209 ZOOM-C now support client-side compilation of CQL into RPN that is
210 sent to the server, enabling CQL to be used against all Z39.50
211 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
212 ZOOM_query object, and submit it using ZOOM_connection_search().
213 The CQL-to-RPN translation uses a configuration file, the name of
214 which must be specified in the Connection's "cqlfile" option.
216 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
217 function, which takes as its start-term parameter a ZOOM_query object
218 (which may have had either CQL or RPN set into it).
221 --- 2.1.10 2005/11/29
223 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
224 GFS to support this as well. Backend handler, bend_srw_update, does the
225 update work. Code contributed by Ko van der Sloot.
227 Allow retrieval of Search Result-1 information in ZOOM by the use of
228 options that are attached to a result set. ZOOM documentation updated
231 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
232 UTF-8 conversion. Patch by Raj Patel.
234 Added option -m to GFS to control formatting of timestamps in log file.
236 Added 'exit' as synonym for 'quit' in yaz-client
238 Added support for specifying SRW resultSetId + resultSetIdleTime in a
239 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
240 for the new members. Patch by Ko van der Sloot.
242 Added support for SRU POST. It is supported for content-type
243 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
245 Do not build the separate Multi-threaded (MT) library libyazthread.la.
246 Instead make the library libyaz.la multi-threaded. Threading as a whole
247 can still be disabled by configure option --disable-threads. Previosly,
248 with older GLIBCs there were problems with MT libs under Apache. This
249 has now been fixed a long time ago.
251 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
254 CQL module modified to be case insensitive for relations/indexes/operations.
256 Fixed bug in CQL transform code: incorrect value relationModifieder
259 Added 'show all' command for yaz-client which retrieves all results
262 Added new yaz-client, xmles, which takes a (private) OID and
263 a document to be sent as an extended service request.
265 Describe new yaz-client commands wait_response and set_auto_wait.
267 Increase TCP/IP listener backlog from 3 (which I am guessing was
268 copied from the SunOS manual entry way back when) so SOMAXCONN, so
269 that the socket will queue as many incoming connections as it's able
270 to handle ongoing connections. In other words, it will never now
271 refuse a connection that it would be able to handle merely because
272 it's not got around to accepting() enough of the pending connections
273 yet. This is the behaviour anyway under Linux, where the listen()
274 argument is ignored; but not under BSD and on systems such as
275 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
276 YAZ-based servers should now be uniform across operating systems in
279 yaz-marcdump uses 64-bit file access on some systems. This is enabled
280 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
281 This allows yaz-marcdump to read large MARC batches (>2 GB).
283 Modified all YAZ source files - except the source which is auto-generated
284 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
287 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
288 corresponding to the existing *_setl() function. These allow option
289 values containing arbitrary valuues.
291 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
292 ZOOM_resultset_sort() in new applications. Its behaviour is identical
293 except that it returns an indicator of whether or not the sort
294 criterion was accepted (0 for OK, -1 for invalid).
298 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
299 MARC output rather than returning "new" buffer.
301 yaz-client warns about unknown init options.
303 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
307 Added support for SRW sort in Generic Frontend Server. Patch
308 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
309 sortKeys - or NULL if none is provided.
311 Fixed bug #307: It was impossible to specify indefinite/no timeout
312 for ZOOM_event. Special timeout value -1 now means indefinite timeout
315 Added support for multiple languages and charsets to be specified in
316 ZOOM. Each charset/language is separated by a blank. If negotiation is
317 in effect in init-response, Option
318 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
319 Code based on patch by Vasiliy Osadchuk.
321 Fixed bug #306: infinite recursion that occurred when calling
322 yaz_log_level_init as the first call (before other log level or
325 Fixed bug in scan handling in front end server: if preferred-Position-In-
326 Response was non-present, a NULL pointer referece was performed.
330 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
331 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
332 now defined for all those error codes. So instead of putting 109 in
333 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
334 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
336 Modified the yaz-marcdump utility to skip garbage bytes between MARC
339 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
341 Program yaz-client now exits and produces an error message if multiple
342 Z39.50 servers are specified on the command line (none or one allowed
345 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
350 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
352 Fixed bug #272: Preserve spacing for CCL terms.
356 Added support for virtual hosts and multiple backend servers for
357 the YAZ frontend server. The configution is XML based and
358 support specificition of CQL to RPN mappings and explain information.
359 See section "Virtual Hosts" in the YAZ manual.
361 Extended OPAC display utility. OPAC display utility renders
362 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
363 to supplement yaz_marc_decode_wrbuf.
365 Fixed a bug in MARC decoder that could caused it to crash for some
366 invalid MARC records. More diagnostics and warnings where added in
367 XML output (warnings, etc are stored in comments).
369 --- 2.0.34 2005/02/08
371 Fixes for UNIX domain sockets. Bug #261.
373 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
375 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
376 Added yaz_marc_subfield_str which defines subfield lead string which is
377 used in YAZ_MARC_LINE format. Default string is blank+$. Added
378 yaz_marc_endline_str which defines end of fields string used in
379 YAZ_MARC_LINE format. Default string is newline.
381 Experimental support for MarcXChange. This format can be produced
382 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
383 http://www.bs.dk/standards/MarcXchange.xsd
385 Added yaz-client commands scansize that sets maximum number of
386 entries to be returned by scan.
388 --- 2.0.32 2005/01/11
390 Added support for SRW scan in yaz-client and Generic Frontend Server.
392 * Added whereInList member to SRW Scan Term.
394 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
396 Fixed NMEM system to return aligned blocks on the smallest boundaries
397 that are suitably aligned for all possible types on the particular
398 architecture YAZ is being built for.
400 --- 2.0.30 2005/01/04
402 Fixed numerious warnings that was issued with newer versions of GCC.
404 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
405 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
408 Make YAZ Generic Frontend Server slightly faster.
410 Enhance (and reduce) logging for Generic Frontend Server.
412 Revert YAZ log system so that it flushes every write operation
413 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
415 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
416 instead of LOG_, due to name clash with syslog(3). LOG_ are still
417 present. New applications should define YAZ_USE_NEW_LOG=1 - this
418 will effectively disable old definitions.
420 --- 2.0.28 2004/11/09
422 Added yaz_log_time_format which specifies log format using
425 Added yaz_log_module_level which returns mask for a module. Value
426 is non-zero mask a if module is enabled; zero if disabled.
428 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
429 in include/yaz/cql.h.
431 Fixed bug #176: Dont throw diagnostics on empty SRU args.
433 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
435 Fixed bug #172: RPM builds does not enable SSL.
437 Doxyfile.in part of dist. Doxyfile generated by configure.
439 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
440 are given and the corresponding component does not exist.
442 Extend CCL documentation in YAZ reference. Describe r=r.
444 --- 2.0.26 2004/10/01
446 Fixed MARC->MARCXML conversion to properly deal with
447 fields, subfields, indicators having non-ASCII characters.
449 Fixed MARC->MARCXML conversion so that ASCII control characters
450 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
453 Added YAZ GFS support for conversion from Z39.50 surrogate
454 diagnostics to SRW surrogate diagnostics.
456 Bug fix: YAZ GFS did not return schema in explainResponse.
458 --- 2.0.25 2004/09/30
460 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
461 now converts recordSchema to elementSetName as well as schema URI.
463 Fixed bug in COMSTACK that prevented HTTP request packages from being
466 --- 2.0.24 2004/09/29
468 Added CCL facility r=r "range" which is similar to r=o "ordered" but
469 does not require white-space before and after the dash in a range, e.g.
470 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
473 Fixed a few AC_TRY_LINK configure tests that did not operate properly
474 due to new GCC removing "redundant" code.
476 Added yaz-client commands scanpos and scanstep that sets preferred
477 position and step-size for scan.
479 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
481 Added CCL utility ccl_qual_buf which parses one or more CCL
482 spec lines in a buffer.
484 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
485 of name and value - ignoring empty lines and comments.
487 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
489 Added odr_get_element_path which returns current element path for an
490 ODR handle. This utility is useful in error handling or user-defined
493 Added ODR_PRINT utility odr_set_stream which is is a more generic
494 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
495 to a write function and pointer to close function. The close function - if
496 non-NULL - will be called during odr_destroy.
498 Fixed bug in CCL parser where truncation char was not removed from
499 right side when truncation=both was in effect.
501 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
504 --- 2.0.23 2004/08/11
506 Fix buffer overrun in CQL parser when dealing with proximity (%).
508 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
509 to UTF-8/UCS conversion is now only based on codetables.xml.
511 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
513 --- 2.0.22 2004/08/06
515 Add support for more "commit changes" in ZOOM (uses Extended Services).
517 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
520 Yet another small fix for configure of SSL.
522 --- 2.0.21 2004/05/14
524 Fix SSL libs for configure when --with-openssl=DIR is given.
526 --- 2.0.20 2004/05/10
528 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
530 SSL comstack now uses yaz.pem certificate file on server side
531 by default. Certificate filename can be configured by calling
532 comstack function cs_set_ssl_certificate_file before cs_bind is used.
534 Fix bug regarding multiple calls to ZOOM_connection_connect.
536 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
538 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
539 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
541 ZOOM now allows inspection of X509 peer certificate for verification.
542 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
544 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
545 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
546 as "modular" but it simplifies things.
548 Added cs_get_peer_certificate to that returns peer X509 PEM.
550 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
551 NULL if SSL is unavailable.
553 Documentation about MARC decoding tools.
555 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
557 --- 2.0.19 2004/03/30
559 Rename CHANGELOG to NEWS to follow GNU style packing.
561 Fix bug with missing initialization of member in init_diagnostics.
562 This bug affects threaded version of GFS server.
564 --- 2.0.18 2004/03/20
566 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
569 Ensure zlib.dll is packed with Windows install.
571 --- 2.0.17 2004/03/17
573 Fix encoding of xsd:string to use text instead of CDATA.
575 Fix endless loop in CQL parser with unbalanced ".
577 Use a more compact way to store MARC-8 conversion tables.
579 --- 2.0.16 2004/03/16 Debian only
581 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
584 Update CQL parser to use new CQL 1.1 modifiers for booleans and
589 --- 2.0.15 2004/03/01
591 Another fix for decoding of XML packed records.
593 --- 2.0.14 2004/02/25
595 Fixes for Chunked encoding. White space not ignored after length spec.
597 Update NS and use default NS for SRW diagnostic elements.
599 --- 2.0.13 2004/02/23
601 Implement ZOOM_resultset_cache_reset which resets record cache.
603 Implement ZOOM_resultset_sort which sorts a result set.
605 Implement chunked HTTP transfer.
607 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
609 --- 2.0.12 2004/02/16
611 Added member 'schema' to bend_explain_rr structure so that backend
612 can specify explain record identifier. Defaults to Zeerex 2.0.
614 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
616 --- 2.0.11 2004/02/16
618 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
621 Added init command for yaz-client which sends "extra" init request.
623 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
624 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
626 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
628 Make ZOOM error code for "invalid query".
630 Fixed compilation for SSL which wasn't properly enabled for all platforms.
632 --- 2.0.10 2004/02/05
634 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
637 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
639 Added option -p <file> to make Generic Frontend Server to write PID file.
641 Added option -D to put Generic Frontend Server in background on its own.
643 Make ZOOM C recognize option "password". If unset, "pass" is used
644 (for backwards compatibility).
646 Fixed a bug in Generic Frontend Server that could make it crash if a
647 client sets characterSetNegotation bit, but didn't pass negotiation stuff
650 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
651 Must be issued before open, in order to be in effect.
653 --- 2.0.9-6 2004/01/12 Debian/Windows
655 Make the SRU server more picky WRT unknown params, etc.
657 Bug fix: ZOOM scan response didn't return displayTerm - when present.
659 New YAZ client command, options, that sets Z39.50 options.
661 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
662 options from a string of tokens (one token for each option bit).
664 Update SRW diagnostic code messages.
666 --- 2.0.9-5 2004/01/07 Debian/Windows
668 Handle user defined stylesheet for SRW/SRU.
670 --- 2.0.9-4 2004/01/06 Debian/Windows
672 Fix bug in decoding of Content-Length.
674 --- 2.0.9-3 2004/01/06 Debian/Windows
676 Fix a bug with decoding of XML packed records.
678 --- 2.0.9-2 2004/01/05 Debian only
680 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
682 Fix bug in SRW/SRU diagnostics decoding.
686 Fixed bug in Generic Frontend Server which could drop records exceeding
687 preferred message size. Reported and fixed by Irina Dijour.
689 Fixed calculation of package size for structured records in Generic
690 Frontend Server. Reported and fixed by Irina Dijour.
692 Fixed namespace for SRW/SRU diagnostics.
694 Fixed SEGV in yaz-client that occured for HTTP connection errors.
698 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
699 this version is incompatible with version 1.0 and older YAZ SRW/SRU
702 CQL changes to reflect recent changes to the specification:
703 * Documentation talks about context sets instead of index sets.
704 * Documentation talks about indexes instead of qualifiers.
705 * The CQL-to-PQF transformer's configuration file now uses
706 "index.set.name = <attributes>" instead of the old form
707 "qualifier.set.name = <attributes>". (Both forms are still
708 understood but the latter is deprecated.)
709 * CQL terms with no explicit index specified are now interpreted as
710 cql.serverChoice instead of srw.serverChoice (which of course
711 behaves exactly the same.)
715 MARC conversion can now generate ISO2709 output in another
716 character set. yaz-marcdump uses this facility if you invoke it
719 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
720 functions from there can be used from C++.
724 Frontend server now transfers memory from decoded packages to stream
727 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
728 references to show up.
730 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
731 the ZOOM Abstract API. The older names for the same options are still
732 also supported for the benefit of old applications.
734 ZOOM-C supports "implementationId" and "implementationVersion" options
735 to go along with "implementationName". These allow the user code to
736 specify identification strings to be sent to servers.
737 Add OID for the new ExtLite attribute set.
739 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
740 as requested/supplid by Ere Maijala <ere@atp.fi>
742 For generic frontend server, reverse the order of
743 "toolkit-supplied / application-supplied" strings sent as implementationId,
744 Name and Version. Also, remove the spaces around the slash. This brings
745 the GFS in line with the behaviour of ZOOM-C on the client side.
747 Add function ZOOM_scanset_display_term.
749 yaz-client shows scan displayTerm if present.
751 Utility yaz-iconv is now installed by default along with the man page
754 Extend configure check for OpenSSL to use pkg-config where available (such
757 Incorporate patch by Morten Bogeskov which allows a Unix file socket
758 server to specify uid/gid/mask for socket using the format
759 unix:[user=uid,][group=gid,][umask=mask,]file=path
760 If file= is omitted the existing format is assumed, e.g.
762 in which case the mask is 0666 (rw for everybody).
764 Major restructure of YAZ source. All source in libyaz is in src directory.
765 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
766 util (utility programs such as ASN.1 compiler, yaz-marcdump).
768 Added man page for utility yaz-marcdump (used to be called marcdump).
769 yaz-marcdump is installed by 'make install'.
771 Fixed a memory leak in Generic Frontend Server that occurred when decoding
772 of incoming package failed.
774 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
776 Change prototype of odr_perror: add const to message string.
778 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
780 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
781 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
782 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
783 DNS lookup. There should not be any compatibility problems with this
784 assuming that blocking=1 or 0 is used.
786 Fix bad reference in UNIX comstack in function cs_addrstr.
788 Fix for compilation on AIX.
790 The generic front-end server (server/seshigh.c) now supports returning
791 Init diagnostics to the client in User-information-field, in
792 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
797 Allow any CQL relation (not just all,any,exact,scr).
799 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
800 that features the same UI.
802 Implemented command update0 in YAZ client which is equivalent to
803 update but uses old of Ext Update ASN.1.
805 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
806 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
807 Previously no OID was used for this info.
809 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
810 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
811 returns 'malformed search term' otherwise.
813 SortResponse member resultCount now set to NULL in sort handler of
816 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
819 Add three new utility functions for translating OIDs between various
820 formats -- symbolic name such as "Usmarc", minus-1-terminated int
821 arrays and dotted strings such as "1.2.840.10003.9.5.1":
822 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
823 char *oid_to_dotstring(const int *oid, char *oidbuf);
824 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
826 Reverted modifications for ES Update definition for z_IU0Update
827 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
828 is back to YAZ 2.0.2.
830 String value attributes for CCL parser.
832 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
833 which their FirstSearch server returns in Init responses, sometimes
834 carrying useful diagnostic information when Init fails. This has the
835 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
836 "z39.50/oclcui.asn", where its definition is somewhat different from
837 what OCLC document on their web-site, as required to interoperate with
840 Support for anonymous authentication in yaz-client. Use the command
843 * Fix the OID of the Index Data-local "admin" Extended Service from
844 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
845 the 1000, which indicates a locally-defined OID, was a mistake.
849 Fix CCL directive @case handling so that it affects string match for
850 both CCL keywords and qualifiers.
852 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
853 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
854 Decoder has been updated with ASN.1 changes as listed in
855 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
856 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
857 z_IUUpdate, remains unchanged.
859 ZOOM_record_get may now return a record in a specific character set.
860 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
861 "from" is the character set of record as returned by target. "to" is
862 the character set to be returned. If omitted, "to" is UTF-8.
864 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
866 New ODR utility, odr_getelement, which returns name of element for
867 which encoding/decoding failed.
869 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
870 in cases where a required element was omitted.
872 Bug fix: some MARC8 sequences were not converted.
874 New ZOOM option "step" which specifies number of records to be
875 retrieved in one chunk. Used in conjunction with "start" and "count".
877 SRW support for yaz-client. Use scheme http: to use it, e.g.
880 yaz-client no longer does (un)intelligent character set conversions
881 by default. Can be enabled with charset and marc_charset commands.
883 xmalloc trace fix for 64-bit systems such as DEC alpha.
885 Solaris 2.6 compile fix.
887 New function, cql_strerror() translates SRW error codes, as returned
888 by cql_transform_error(), into human-readable English strings. Used
889 in yaz-client diagnostics when appropriate.
891 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
892 converts it into a type-1 query which is sent to the server. This
893 makes CQL available for use with all Z-servers, as opposed to the tiny
894 minority that can handle CQL queries themselves.
898 New Debian package layout similar to the Redhat Package layout.
900 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
901 and search result respectively.
905 Redhat package is now several packages: libyaz (runtime libraries),
906 libyaz-devel (development and documentation, and yaz (utility programs).
907 Package spec file by Morten Bøgeskov.
909 New member 'schema' in struct bend_fetch_rr which the name of requested
910 schema (SRW/SRU) for record (or NULL if none was given). The fetch
911 handler MAY set this to reflect the schema of the returned record.
913 New member 'display_term' in struct scan_entry. GFS now sets member entries
914 and allocates scan entries to be filled by user scan handler. In previous
915 version, entries member was allocated by the scan handler. That still works,
916 but the GFS will ignore member display_term - assuming it was NOT set by
917 the handler. The fact that the GFS now allocates the entries both allows
918 for new members and makes a scan handler easier to write.
920 Fix CQL lex buffer overflow.
922 SRW/SRU recordPacking. For SRW default recordPacking is string. For
923 SRU default recordPacking is string.
925 SRU protocol support for frontend server.
927 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
929 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
931 Added scan for the ZOOM shell (zoomsh).
935 * String Identifers for Schemas (Amendment 5).
936 http://lcweb.loc.gov/z3950/agency/amend/am5.html
937 Old definition for schema
938 Odr_oid *schema; /* OPT */
943 Z_InternationalString *uri;
944 #define Z_Schema_oid 1
945 #define Z_Schema_uri 2
948 * resultCount parameter to Sort Response (Amendment 1).
949 http://lcweb.loc.gov/z3950/agency/amend/am1.html
951 Support for SRW 1.0 over HTTP. This is an optional feature and
952 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
955 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
956 on the same port. SRW SearchRetrieveRequests are mapped
957 to bend_init,bend_search,bend_fetch,bend_close.
959 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
961 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
962 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
964 ZOOM connections are SRW based if schem http is used for hostname
965 in connect, e.g. z = ZOOM_connection_new("http://myserver");
966 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
968 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
969 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
970 distance=n, order=true/false, relation=le, prox unit=word. If
971 n is omitted, distance 1 is used.
973 Fixed problem with C compiler include path in wrong order.
975 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
976 on Solaris. Patch from Ko van der Sloot.
978 New MARC decode API. All new functions operate on a yaz_marc_t
979 handle. The most important new functions are: yaz_marc_create,
980 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
981 decode and destroy respectively. Decoder can produce formats
982 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
983 include/yaz/marcdisp.h.
985 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
986 to UTF-8, UCS-32, wchar_t or Latin-1.
988 * Prototypes for yaz_iconv_-functions moved to separate header
989 include/yaz/yaz-iconv.h.
991 Make a few private functions 'static' in unix.c. This prevents
992 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
994 For ZOOM connection, the options targetImplementation{Id,Name,Version}
995 are set when Init Response is received.
997 New function ZOOM_connection_error_x similar to ZOOM_connection_error
998 but returns diagnostic set as well.
1000 New function yaz_strerror which is a portable wrapper for
1001 strerror/strerror_r/GetLastMessage.
1003 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1004 is returned for MARC. If type is "oai", then OAI MARC is returned.
1006 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1009 --- 1.9.2 2002/11/26
1011 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1013 Fix bad race conditions on SIGTERM and terminate gracefully in
1016 Move retrieval (data1) module to Zebra since nobody seems to be
1019 Add GRS-1 render for ZOOM using same format as yaz-client.
1021 --- 1.9.1 2002/10/05
1023 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1025 Fix broken ESpec handling in data1 module.
1027 SGML reader parses comments and makes them part of the data1 tree.
1029 Added several type casts so that YAZ compiles as C++ code.
1031 ZOOM didn't handle PDU encoding failures properly.
1033 Added more Bib-1 diagnostics (approved extensions).
1035 GNU configure: better check for iconv.
1037 More portable use of accept, getpeername. Check for socklen_t. Use
1038 int/size_t if socklen_t is not defined.
1042 PQF parser rejects bad queries - including those with extra
1043 characters in them. PQF parser used to silently ignore that.
1044 Cleaner API for PQF added, which allows you to get detailed
1045 error information for bad queries (see yaz/pquery.h).
1047 Fixed bug in ZOOM_record_get for type "database".
1049 Implemented mini iconv library supporting conversions between
1050 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1052 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1054 --- 1.8.9 2002/08/20
1056 Fixed ZOOM C record cache so that preferredRecordSyntax and
1057 elementSetName is used to check for already fetched records.
1059 --- 1.8.8 2002/08/02
1061 Added three members in bend_initrequest structure to facilitate
1062 character set negotiation.
1064 Fixed a bug in frontend server that could cause indefinite
1065 loops under rare conditions.
1067 Revised character set utilities (charneg.h) so that encoding
1068 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1070 For PQF, directive @term <type> sets term type for Scan/Search.
1071 Here <type> is general, string, numeric, null. The term type
1072 is inherited - just like @attr.
1074 New call odr_set_charset that sets character set conversion for
1075 international-strings on a ODR stream. Prototype is:
1076 int odr_set_charset(ODR o, const char *to, const char *from);
1077 The InternationalString is still represented as C string in YAZ
1078 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1079 won't). On the protocol level, you can use any encoding.
1081 Support for UNIX sockets in ZOOM.
1083 Solaris recv sometimes returns errno == ENOENT. It is treated as
1084 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1086 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1087 both client and server. Code by Morten Bøgeskov.
1089 --- 1.8.7 2002/05/22
1091 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1092 that they can be used directly from Visual Basic. You must recompile
1093 your windows APP if you're using ZOOM.
1095 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1096 Commands "lang" and "charset" sets language and character set respectively.
1097 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1098 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1100 Attributes from multiple CCL fields may be OR'ed rather than merged
1101 using directive "@field or". Fields are still merged by default -
1102 equivalent to "@field merge".
1104 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1107 Fixed bug in zget for parameter ExtendedServicesResponse.
1111 --- 1.8.6 2002/03/25
1113 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1115 Client displays USR.1:SearchResult-1 (hits per term).
1117 Additional Search Info for search in Generic Frontend Server.
1119 Fixed CCL parsing of "field=s".
1121 WIN32 installer - using the excellent NSIS software from nullsoft.
1123 Fixed CCL parsing of "field = - <number>".
1125 Added function yaz_marc_decode that decodes MARC for line mode
1126 display or XML (similar to that used by JZKit).
1128 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1129 Z39.50. But ISO/ILL was, however.
1131 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1132 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1134 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1135 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1137 --- 1.8.5 2002/02/03
1139 New YAZ client features: Command completion and new commands:
1140 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1141 Code provided by Jacob Poulsen.
1143 New call oid_trav, that visits all registered OIDs via callback.
1145 Function ZOOM_record_get now returns const char pointer rather than
1146 void pointer. It saves a lot of type casts.
1148 For YAZ client, command "auth" now allows you to set authentication
1149 in IdPass style. It is enabled when three tokens are given - order
1150 is user, group and password.
1152 Fix memory leaks in MARC record handling for ZOOM.
1154 New option for YAZ client, -k <kilobytes> that sets
1155 maximum record size. Similar to -k option for generic frontend
1156 server and yaz-ztest.
1158 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1160 Prefix query parser reports "fail" when bad attribute set is given.
1162 Fix in MARC decoder. Proximity logging. Fix for attribute set
1163 in scan handler for server. Patches by Shigeru Ishida.
1165 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1168 Configure option --with-openssl=<dir> now works when a directory is
1169 specified. Patch provided by Morten Bøgeskov.
1171 New option for YAZ client, -u <auth>, that sets authentication.
1173 ZOOM fix: error information was sometimes "missing", since error
1174 was cleared/reset too when it shouldn't.
1176 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1178 --- 1.8.4 2002/01/04
1180 Scan for ZOOM API. New object ZOOM_scanset. New functions
1181 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1182 ZOOM_scanset_destroy.
1184 New ZOOM function, ZOOM_connection_last_event, that returns type
1185 of last event (such as "receive data", "send data", "apdu received",
1188 New ZOOM option, schema, that specifies schema for retrieval.
1190 New CCL feature. Qualifiers can be aliases for one or more
1191 other qualifiers (if more than one is given, OR is used).
1193 ZOOM uses named result sets if target supports it.
1195 Two new YAZ client commands: . (dot, which sources a script of YAZ
1196 client commands), and ! (to execute shell command.). Implemented
1199 Working on Debian packages.
1201 --- 1.8.3 2001/11/19
1203 YAZ client enables named result sets only if target supports it.
1205 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1207 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1208 with key="host" to get same result.
1210 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1211 Function Z3950_resultset_record(s) returns references to records
1212 "owned" by resultset. To become owner use Z3950_record_clone.
1214 Function z_ext_record handles Extended Services. Thanks to
1217 --- 1.8.2 2001/11/12
1219 CCL Parser fix: ignore token comma when dealing with and-lists.
1221 Documentation updates for COMSTACK.
1223 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1224 Changed prototype Z3950_records. For some functions, int parameters
1225 were changed to size_t.
1227 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1230 New MARC decode/display function, marc_display_exl, which properly rejects
1231 non-ISO2709 records. YAZ client uses it.
1233 --- 1.8.1 2001/10/29
1235 Fix bug: local attribute set wasn't set correctly in PQF strings.
1239 * Old Z39.50 codecs no longer supported.
1241 Added ZOOM C binding. See http://zoom.z3950.org/
1243 Renamed states for COMSTACKs to avoid confusion with events.
1245 Implemented cs_look and proper cs_rcvconnect.
1247 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1249 Configure detects POSIX threads on OpenBSD.
1251 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1252 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1254 When error is returned from present handler, non-surrogate diagnostic
1255 is returned in present response (and fetch handler is no longer called).
1257 * Minor adjustments to pquery parser (PQF). Token characters may be
1258 escaped by using backslash (C-style).
1260 PQF parser allows string attribute values to be specified. For @attr,
1261 non-numeric characters after the equal-sign are treated as strings
1262 (e.g. @attr 9=title).
1264 CCL trunction character may be defined (@truncation in file)
1266 * function zget_ExtendedServicesRequest sets waitAction to
1267 waitIfPossible (was wait).
1269 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1272 CCL operator names may be set in field definition files (CCL_bibset).
1273 See ccl/bib1 for an example.
1275 Fixes in ASN.1 compiler for C++ compatibility.
1277 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1278 and "op_or" to avoid conflict with C++.
1280 Fixed problem with GNU readline detection on Redhat 7.0.
1282 Added step-size for Scan backend handler.
1284 Fixed bug that made the frontend server crash when no attribute
1285 set was specified for scan.
1287 Front-end server automatically switches to original working directory
1288 when installed as an NT service. Previously -w had to be specified to
1291 Added extended attributes for retrieval module (data1), so that data1
1292 records carry d1_readXML/SGML attributes. d1_read also supports
1293 null-data rules ( <tag/>)
1295 On UNIX when POSIX threads are available, a separate library libyazthread
1296 is created. Programmers should link with that library and the yaz library
1297 when using threads. The reason for the split was that some applications
1298 on Linux, such as Apache, doesn't work well when using shared objects that
1301 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1302 (or any frontend server) in SSL mode by specifying ssl: followed by
1303 address. Only tested on UNIX.
1305 Added feature for CCL module. Virtual structure s=al or s=ol generates
1306 and-list and or-list respectively instead of phrase search.
1310 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1311 log_mask_str. This was done to avoid name conflicts with other libraries
1312 (such as other PHP extensions).
1314 Added raw OID member for preferred record syntax (request_format_raw)
1315 and returned record syntax (output_format_raw) for backend fetch method.
1317 Config file yaz-config now accepts options so that it returns specific
1318 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1320 Shared library support for UNIX using GNU libtool.
1322 * Modified backend interface. Request/Response struct's replaced by
1323 one read/write C struct. For example bend_fetchrequest and
1324 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1325 Every handler - even search has to be registered in bend_init
1326 handler. This means that the YAZ library no longer refers to
1327 external functions and it makes it possible to make the whole
1328 thing a single DLL/SO.
1330 Added Segment handler for backend server.
1332 Added Zmbol/Zebra administrative functions to YAZ client.
1334 Threaded frontend server on UNIX (when POSIX Threads are available).
1335 Starting the server with option -T enables multi-threading.
1339 Added configure option --enable-comp/disable-comp to control use
1340 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1341 located in sub directory asn.
1343 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1344 in ${exec_prefix}/bin along with the other programs yaz-client and
1347 GNU automake used to maintain makefiles.
1349 Added several OID's.
1351 Changed retrieval module so that we can load records with no abstract
1352 syntax defined. Tagpaths in these records are fully composed of string
1355 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1359 On UNIX, the generated makefile now supports a proper 'make install'.
1360 The prefix can be set via GNU configure to set the install location
1361 (default is /usr/local).
1363 * YAZ programs client and ztest were renamed to yaz-client and
1364 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1365 locations, such as /usr/bin,/usr/local/bin,etc.
1367 * YAZ Header files were moved from include to include/yaz. YAZ Header
1368 files are referred to as include <yaz/log.h> rather than <log.h>.
1369 The YAZ include path (-I ..) is therefore the same as before. Programmers
1370 should update their #include statements or use -Ipath/include/yaz
1371 instead. The main motivation for doing this change is that YAZ header files
1372 can be installed in "standard" locations /usr/include,/usr/local/include
1373 without introducing conflicts, since ALL YAZ header files are stored
1374 in subdirectory yaz (under /usr/include for example).
1376 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1377 rather than project/workspace files. We switched because project files
1378 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1381 Changed name of logging function, logf, to yaz_log, to prevent name
1382 clash with some math-log functions. The YAZ header log.h defines logf
1383 to yaz_log (#define) so there should be no incompatibilities by this
1386 Added bend_start/bend_stop handlers for server. These handler are
1387 called on start/stop of server. For windows they are called whenever
1388 a service is started/stopped.
1390 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1391 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1392 in util/yc.tcl. The auto-generated C code structures are, in a few
1393 cases, incompatible with the old decoders. There are differences in the
1394 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1395 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1396 The preprocessor variable ASN_COMPILED is defined when the compiled
1397 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1398 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1399 wish to use the old encoders/decoders you can specify --disable-yc
1402 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1403 version so that it supports both new - and old version of DB Update
1405 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1406 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1407 change. The name parameter can be set to 0 in which no name is specified
1408 for the construction. The macros odr_implicit and odr_explicit sets name
1409 parameter to zero for the construction involved. New macros
1410 odr_implicit_tag and odr_explicit_tag are similar to the others,
1411 except that a name parameter is added. For programmers' that don't use
1412 ODR they probably only need to change the call to z_APDU and z_External.
1414 Added access control facility by interfacing the TCP wrapper library.
1415 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1416 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1417 name of the daemon and enables the access control as specified in
1418 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1420 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1421 den Dool <H.M.vdnDool@kub.nl>.
1423 Added reference ID parameter to most functions in server API - refer
1424 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1426 Changed name of ccl library to libccl.a (was ccl.a).
1428 Fixed bug in decoder for Explain (Category TargetInfo).
1430 Added support for GNU readline in client. Thanks to Jacob Poulsen
1431 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1433 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1434 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1435 IMPLEMENTATION! This change was made to the development version before
1436 the ZIG decided to retract the amendment. If any users MUST be
1437 compatible with the original Update definition, PLEASE CONTACT US, and
1438 we will include a separate definition corresponding to the old Update
1439 ES. Note that because of the change to the ASN.1 of the
1440 TaskPackageRecordStructure we cannot define a single structure that
1441 will support both versions.
1443 * Added const modifier to buffer parameter for some ODR/BER encoding
1444 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1445 completeWAIS, odr_dumpBER.
1447 Fixed bug in client.c which caused a crash when a scanResponse didn't
1448 contain positionOfTerm.
1450 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1451 * will cause an error in a client if a non-YAZ target sends both a
1452 * list of Scan entries and non-surrogate diagnostics.
1454 Retrieval module enhancements. Tag sets may be typed in the reference
1455 to it. From the .abs-file the "tagset" directive takes a third optional
1456 integer type for the tag set referenced. From a .tag-file the "include"
1457 directive takes a third optional type as well. The old "type" directive
1458 in the tag set itself is still recognized but acts as the default type
1461 Backend interface change. Individual Scan terms returned from bend_scan
1462 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1463 in include/backend.h.
1465 Retrieval module enhancements. Multiple tag sets and attribute sets may
1466 be specified in abstract syntax specs. Revised the error/warning for
1467 logging messages reported by the retrieval module when reading the
1470 Object Identifier system (oid_..) changed. The API is backwards
1471 compatible but the oid-routines now allocates new OID's when needed.
1472 Raw OID's may be specified in oid_getvalbyname.
1474 YAZ now uses GNU configure to generate Makefile(s).
1476 * Minor changes in some of the member names of DeleteResultSetRequest and
1477 DeleteResultSetResponse. See include/proto.h.
1479 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1480 and added member 'languages' in TargetInfo (which was missing).
1482 Changed the way attribute sets are handled in the retrieval
1483 module. These are now cached, just like the abstract syntaxes
1486 Changed YAZ so that it links with compiled ASN.1.
1488 Added Explain-schema definitions and mapping routines. The following
1489 Explain categories have been implemented: AttributeDetails,
1490 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1492 Fixed minor bug in Windows version of Server Library.
1494 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1496 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1498 Added EXTERNAL: UNIverse Resource Report (non-standard).
1500 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1501 ENUMERATED and SET OF.
1503 * Added 'const' to some of the char pointer arguments for the
1504 functions, data1_read_node, data1_getelementbytagname,
1505 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1508 Fixed bug in data1_insert_taggeddata - the last_child member of
1509 parent wasn't initialised.
1511 * Changed data1_read_record and data1_read_node so that the supplied
1512 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1513 doesn't refer to any parts of the "SGML"-buffer.
1515 Fixed bug in server library (Windows version of statserv_remove).
1517 * Changed code so that it compiles as C++. The type definition
1518 of Odr_fun which is a member of Odr_arm was changed. The result is,
1519 that an explicit typecast is needed for the fun pointer when
1520 using Odr_arm - as in:
1521 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1523 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1525 Implemented the new structured date and time definition as approved
1526 by the ZIG. Added schemaId element to the specificTag in Espec-1
1527 (also approved at the last ZIG). Thanks to RVDM.
1529 Added some Object identifiers (RVDM).
1531 Changed the Update Extended Service (RVDM).
1533 Added command "refid" to client which specifies referenceId for
1534 the following requests.
1536 Implemented extended service handling for server. See ztest.c
1537 for an example as well as backend.h. New handlers are registerd
1538 in the Init handler.
1540 * Changed interface for sort in server.
1542 Added new members to statserv_options_block. It allows a server
1543 to read options from another source than just the command line. Thanks
1544 to Charles Woodfield.
1546 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1547 renamed to zboolean. Some C++ compilers complained about the name.
1549 Minor changes to gils.abs. Added index 's' (sort) on title
1550 and date/time-last-modified.
1552 --- 1.4pl2 1998/1/30
1554 Fixed bug in server library regarding inetd mode (-i). This bug
1555 was introduced by release 1.4.
1557 --- 1.4pl1 1998/1/29
1559 Added sort facility in client and backend server interface.
1561 Fixed problem with dependencies in Makefile(s).
1563 Fixed bugs for encoders/decoders of extended services and
1566 Implemented sub-tree feature for schemas. Sub-trees are
1567 referenced in *.abs-files. See explain.abs for an example
1568 of the use of this feature.
1570 Modified bib1.att; local attributes for ANY didn't include
1571 ANY itself (only affects use of the retrieval module).
1573 Fixed bug in plain SGML reader in function data1_read_node:
1574 tags with prefix "var" was incorrectly interpreted as variants.
1576 Added feature "sub-schemas" to enable references to - and definitions
1577 of - group of elements.
1579 * Removed member parent from type data1_element (in data1.h).
1581 Implemented function odr_nullval() that returns the value of
1584 * Removed member num_children from data1_node (in data1.h).
1586 Made NT service interface part of the server library. The
1587 function statserv_main uses the NT service when required and
1588 calls the statserv_start / statserv_close routines.
1590 Routine zget_SearchRequest and zget_PresentRequest fills
1591 resultSetName/Id member with "default" instead of "Default".
1593 Fixed memory leak in server. Request queue member wasn't freed.
1595 Fixed nmem_exit so that memory is freed.
1599 Revised the CCL parser utility to be thread safe.
1601 Added function, oid_ent_to_oid, to replace the function
1602 oid_getoidbyent, which is not thread safe.
1604 * Added nmem_init and nmem_exit to initialize and release
1605 NMEM resources. Function nmem_init should be called once in the
1606 initial thread before NMEM/ODR is used. statserv.c and client.c
1607 have been changed accordingly. The change was necessary to make
1608 NMEM thread safe. The NMEM memory pool is shared amongst threads
1609 in a process. Unix-based applications will still work fine without
1612 Added NT Services interface for the the Z39.50 (statserv) Server.
1613 Refer to the ztest.c source on the usage.
1615 Windows 95/NT port using MSVC5.0. Project files are included in the
1618 * Defined new 'global' handle for the retrieval (data1) system. The
1619 new handled, data1_handle, describes the state of the data1 system.
1620 This handle is passed as first argument to virtually all
1621 data1 related routines. The functions data1_create and data1_destroy
1622 creates and destroys a data1 handle respectively.
1624 Added ODR encode stream member to all backend request structures
1625 init, search, scan etc. This stream should be used to allocate all
1626 memory used for the response when thread safe operation is needed.
1628 Changed the comstack utility, cs_addstr, to be thread safe. The
1629 returned hostname string returned by the function is now part the
1632 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1633 function. The cs_straddr takes a COMSTACK handle as argument, so this
1634 function must be used after cs_create and before bind/connect.
1635 This function is thread safe.
1637 Moved test server to 'ztest' directory - generic server code still
1638 in 'server' directory.
1640 Made prefix query (pquery.c) utility thread safe.
1642 Added new function modifier YAZ_EXPORT to 'export' public DLL
1643 functions when using windows (see include/yconfig.h).
1645 Added definitions to the OID database (util/oid.c) (RVDM).
1647 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1649 Added call to ccl_rpn_delete in client program.
1651 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1652 release of RPN structure.
1654 Added support for C++, headers uses extern "C" for public definitions.
1655 With input from RVDM.
1657 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1658 Thanks to Ronald van der Meer (RVDM).
1660 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1662 Added support for private extensions to the OID database
1663 (oid_setprivateoids()). Thanks to RVDM.
1665 Added optional, physical ANY (key replication)
1667 Fixed null-reference problem in GRS-1 output filter.
1669 Proximity operator added to Prefix Query Format (PQF).
1671 In test client command "base" accepts multiple databases.
1673 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1677 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1679 Smallish bug-fixes in the new encoders/decoders (explain).
1681 Bug fixed in DeleteRequest.
1683 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1685 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1687 Added SOIF syntax (using private OID for now) to retrieval module and client.
1689 Added Update extended service.
1691 Added SearchResult-1 additional info structure.
1693 Added optional CCL (ISO8777) interpreter as separate module. Available
1696 --- 1.2 1996/6/10 (1st anniversary release)
1698 Added Summary record syntax. Lightly tested.
1700 Added OPAC record syntax. Untested.
1702 Added ResourceReport service encoders/decoders. Untested.
1704 Fixed bug in z_Unit - wrong tagging on unitSystem.
1706 Fixed bug in the DiagRecs decoder.
1708 Added options for max PDU size and session timeout to frontend-server.
1710 Added documentation of query-language parsers and other supporting utilities.
1712 [frontend-server] Added Attribute set to the bend_scanrequest API.
1714 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1715 surrogate diagnostics were generated.
1717 [retrieval] Allow multiple local values for attribute.
1719 [retrieval] Allow multiple attributes per element in .abs files. index type.
1721 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1723 --- 1.1pl2 1996/4/10
1725 Minor changes, mostly specific to Zebra's requirements (retrieval)
1729 Repaired bug in frontend server when running multiple listening
1730 endpoints in dynamic mode.
1732 z_External() now won't break if a known, ASN.1 value comes encapsulated
1733 in an octet-string. The value will pass through unmodified in an Odr_oct.
1735 Added a bit of code to the demo client to decode & display
1736 ASN.1-structured records represented in the octet-aligned branch of
1737 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1739 Added z_ext_getentbyref() to the ASN module. Doc updated.
1741 * Completed the SCAN definition in the ASN module. This may break SCAN
1742 code based on older YAZ-versions at compile-time. The fix is easy -
1745 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1746 under the SCAN definition. Remember to initialize this, server-people.
1748 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1749 that this does not extend to ODR and ASN.
1751 Comstack allows insertion of established socket (primarily for
1752 inetd-operation of servers). Doc updated.
1754 Front-end server can now start from the inetd in TCP mode. Doc
1757 --- 1.0pl4 1996/1/24
1761 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1762 the rank and record number.
1764 Adjustments to the frontend server.
1766 Fixed diagnostic BER dumper. It ignored the file argument.
1770 Various changes to retrieval module.
1772 Changed the union discriminators of the protocol files from enums to
1773 ints paired with #defines.
1775 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1778 *Changed operator in the RPN structure to 'roperator', again to avoid a
1781 Fixed problems in Explain decoders/encoders.
1783 --- 1.0pl2 1995/12/6
1785 Memory bug in log module fixed.
1787 --- 1.0pl1 1995/12/5
1789 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1791 Bug in Explain DatabaseInfo module fixed.
1793 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1797 The shift to v1.0 signals that we now consider the *core* functionality
1798 of YAZ reasonably stable (the core being more or less equivalent to
1799 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1800 tested (Explain not at all - though that will happen soonish).
1802 Minor changes to code to support Windows port.
1804 Various minor changes after we're getting to use GRS-1 & co. more.
1806 Added Espec-1 format.
1808 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1809 of the protocol and it cannot be selected when encoding (maps into 'string'
1810 when decoding). Needed to talk to some servers.
1812 Demo client can request simple element set names.
1814 Added Diagnostic Format encoders/decoders.
1816 Added simple Close handling to frontend server (no hooks for resource
1817 reporting yet), and demonstration client.
1819 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1821 --- 1.0b3 1995/08/24
1823 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1824 handled incorrectly when records were requested in the searchResponse. This
1825 will only affect you if you use the frontend-server.
1827 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1828 Test-client will ask for and print GRS1. Ztest will return dummy records
1831 Added Explain encoders/decoders to the service-level API. Untested.
1833 Added Extended Services: Item Order encoders and decoders to the Service-
1834 level API. Untested. We could use a recent copy of the pertinent bits
1835 of the ILL protocol to add those bits.
1837 Added diagnostic format 1 encoders/decoders to the service-level API.
1840 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1841 odr_cons.c, which causes a more correct output.
1843 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1844 was always set to 0 when no records were requested in the searchRequest.
1846 * Added better external-handling. This shouldn't harm old code that
1847 *encodes* externals. It can break code that looks for a
1848 'single-ASN1-type' representation, since those types that are known
1849 are now decoded immediately. Look at the SUTRS sample code in
1850 seshigh.c and client.c. Documentation updated.
1852 Handling of structured records in bend_fetchresponse. Length -1 marks
1853 structured record, type is deduced from format field.
1855 --- 1.0b2 1995/06/27
1856 Fairly quick maintenance release to add SUTRS support.
1858 Fixed handling of SUTRS records in the demonstration client.
1860 * Added format field to the bend_fetchrequest and bend_fetchresponce
1861 structures of the backend API (frontend server). When the record is
1862 returned, the value of the format field is mapped to an OID. The
1863 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1864 of the record. The special value VAL_NONE in the bend_request means
1865 that no specific format was requested by the client. Documentation
1866 updated accordingly. Test server (ztest) will return a fixed dummy
1867 SUTRS record if your client requests SUTRS.
1869 Documentation updated accordingly.
1871 You can now set external libraries and RANLIB support in the top-level
1875 First public release.
