3 Fixed problem with SRU mode type (soap, get, post) for yaz-client
6 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
10 Fixed MARC ISO2709 encoding routines to deal with character set
13 Minor changes to GFS logging. Database included in search request log
16 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
17 cached/multiple records.
19 Shared libraries are built by default on Unix+configure.
21 Changed cql2pqf transformation to use a different evaluation order. The
22 new order is: always, relation, structure, position, truncation, index
23 and relationModifier. Old order was: always, relation, relationModifier,
24 structure, index, position, truncation. Note that the the latter ones
25 override former ones for identical attributes.. The new scheme means that
26 it is possible to override any existing attribute with a relationModifier.
27 And also that it is possible to override everything for the index rule
28 (except the ones listed in relationModifier). No order is perfect but this
29 one, we believe, covers more real cases.. The "always" should have been
30 called "default", since the attributes there can be overridden with all
33 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
34 compilation phase, but also for yaz-config --cflags output. This allows
35 us to have public headers with Libxml2 stuff in them . It should also,
36 eventually, make Libxml2 checks redundant in packages using YAZ, such
41 Changed SRU update structure bend_update_rr so that SRU diagnostics are
42 stored in uri, message and details.. Previously diagnostics were stored
43 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
44 compatibility.. but he's probably the only one affected, so.
46 Added support for CCL, compiled on the client side, in ZOOM-C. This
47 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
48 input; the resulting query objects can be used for for searching with
49 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
51 YAZ' configure searches for OpenSSL by default.
53 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
54 SL_CTX_use_certificate_file. See
55 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
56 for more info. Thanks to Ko van der Sloot.
60 Bug #600: SRU GET, POST support for yaz-client. Introduced
61 command 'sru' which selects method SOAP/GET/POST.
63 Allow missingValueAction to be specified for the sortspec string -
64 function yaz_sort_spec. By default, the missing value action is null.
65 Use ! to specify "abort". Use = followed by stringvalue to specify default
68 Ensured that Present-handler (if defined) is called in GFS before any call to
69 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
70 searchRetrieve requests.
72 Documentation for YAZ is now based on the Docbook XML/XSLT using
73 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
74 is no longer depending on jade/openjade or docbook-to-man scripts.
75 PDF is no longer part of the distribution - but can optionally be
76 made using DSSSL/jadetex or FOP.
78 Added retrieval handling support in Generic Frontend Server to support
79 conversion between MARC/XML as well as XSLTtransforms. See
80 etc/yazgfs.xml for an example.
82 Added Authentication support to Generic Frontend Server in SRU
83 mode. Authentication using HTTP Basic is supported, as is the use
84 of 'x-username' and 'x-password' parameters in the request itself.
86 Added support for a new character set MARC8s identical to MARC8 except
87 that it converts combined characters to single Unicode characters in the
88 Latin-1 range (when possible).
92 ASN.1 compiler 0.4: generates brief Doxygen file header for
93 generated .h/.c files.
95 Utility yaz_iconv now supports conversion to MARC-8.
97 New facilities for the MARC module. The reading - and writing of
98 content are separate methods for the yaz_marc_t handle. The following
99 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
100 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
101 format). Write functions have prefix yaz_marc_write_.. The existing
102 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
103 available. Removed support for OAI-MARC and simplexml (not the
104 simplexml from PHP5).
106 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
107 to be returned for this connection.
109 --- 2.1.16 2006/03/31
111 Allow multiple languages and charsets to be specified with
112 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
113 negcharset iso-8859-1,utf-8
115 Translation of proximity nodes from CQL into PQF now works.
117 Moved to automake 1.8, 1.9.
119 Added function yaz_log_set_handler which allows a log handler to be
120 installed. This handler will be called for all log messages. Output
121 to file is also produced; but that can be disabled by passing NULL
122 fname to yaz_log_init_file.
124 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
126 For SRW (including GFS), accept application/soap+xml as content-type
129 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
130 produces NO stylesheet reference even if a default stylesheet is specified
133 --- 2.1.14 2006/03/14
135 Updated Windows package to include yazd.dll + yazd.lib for the
136 Development component.
138 If the environment variable YAZ_LOG is set, then it is used as a
139 string indicating the default level of logging to use if not
140 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
141 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
142 used as before. So, for example, to omit warnings from YAZ logging,
145 cql_transform() now map structure and other attributes before indexes,
146 so that index-specific structures and other attributes can override
147 defaults. So now a combination of mapping specifications such as:
149 index.dc.date = 1=date-modified 4=5
150 does the right thing.
152 cql_transform() now also respects the "always" mapping specification,
153 which establishes an initial set of attributes to be used for all
154 terms except where overridden by more specific attributes associated
155 with the index, relation or modifier.
157 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
158 which mode to use; one of "post", "get" or "soap" (SRW, default).
160 Fixes for yaz_iconv routines: changed trie-based character set conversions
161 to use only non-negative values for bit fields due to Sun's C compiler not
162 supporting negative values.
164 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
165 sequences where not read correctly. Fix by Rustam Usmanov.
167 Updated win/makefile to use options, settings which makes things
168 compile with VS C 2005.
170 --- 2.1.12 2006/02/01
172 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
174 In ZOOM socket code, use select instead of poll on MacOSX.
176 ZOOM-C now support client-side compilation of CQL into RPN that is
177 sent to the server, enabling CQL to be used against all Z39.50
178 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
179 ZOOM_query object, and submit it using ZOOM_connection_search().
180 The CQL-to-RPN translation uses a configuration file, the name of
181 which must be specified in the Connection's "cqlfile" option.
183 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
184 function, which takes as its start-term parameter a ZOOM_query object
185 (which may have had either CQL or RPN set into it).
188 --- 2.1.10 2005/11/29
190 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
191 GFS to support this as well. Backend handler, bend_srw_update, does the
192 update work. Code contributed by Ko van der Sloot.
194 Allow retrieval of Search Result-1 information in ZOOM by the use of
195 options that are attached to a result set. ZOOM documentation updated
198 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
199 UTF-8 conversion. Patch by Raj Patel.
201 Added option -m to GFS to control formatting of timestamps in log file.
203 Added 'exit' as synonym for 'quit' in yaz-client
205 Added support for specifying SRW resultSetId + resultSetIdleTime in a
206 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
207 for the new members. Patch by Ko van der Sloot.
209 Added support for SRU POST. It is supported for content-type
210 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
212 Do not build the separate Multi-threaded (MT) library libyazthread.la.
213 Instead make the library libyaz.la multi-threaded. Threading as a whole
214 can still be disabled by configure option --disable-threads. Previosly,
215 with older GLIBCs there were problems with MT libs under Apache. This
216 has now been fixed a long time ago.
218 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
221 CQL module modified to be case insensitive for relations/indexes/operations.
223 Fixed bug in CQL transform code: incorrect value relationModifieder
226 Added 'show all' command for yaz-client which retrieves all results
229 Added new yaz-client, xmles, which takes a (private) OID and
230 a document to be sent as an extended service request.
232 Describe new yaz-client commands wait_response and set_auto_wait.
234 Increase TCP/IP listener backlog from 3 (which I am guessing was
235 copied from the SunOS manual entry way back when) so SOMAXCONN, so
236 that the socket will queue as many incoming connections as it's able
237 to handle ongoing connections. In other words, it will never now
238 refuse a connection that it would be able to handle merely because
239 it's not got around to accepting() enough of the pending connections
240 yet. This is the behaviour anyway under Linux, where the listen()
241 argument is ignored; but not under BSD and on systems such as
242 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
243 YAZ-based servers should now be uniform across operating systems in
246 yaz-marcdump uses 64-bit file access on some systems. This is enabled
247 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
248 This allows yaz-marcdump to read large MARC batches (>2 GB).
250 Modified all YAZ source files - except the source which is auto-generated
251 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
254 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
255 corresponding to the existing *_setl() function. These allow option
256 values containing arbitrary valuues.
258 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
259 ZOOM_resultset_sort() in new applications. Its behaviour is identical
260 except that it returns an indicator of whether or not the sort
261 criterion was accepted (0 for OK, -1 for invalid).
265 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
266 MARC output rather than returning "new" buffer.
268 yaz-client warns about unknown init options.
270 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
274 Added support for SRW sort in Generic Frontend Server. Patch
275 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
276 sortKeys - or NULL if none is provided.
278 Fixed bug #307: It was impossible to specify indefinite/no timeout
279 for ZOOM_event. Special timeout value -1 now means indefinite timeout
282 Added support for multiple languages and charsets to be specified in
283 ZOOM. Each charset/language is separated by a blank. If negotiation is
284 in effect in init-response, Option
285 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
286 Code based on patch by Vasiliy Osadchuk.
288 Fixed bug #306: infinite recursion that occurred when calling
289 yaz_log_level_init as the first call (before other log level or
292 Fixed bug in scan handling in front end server: if preferred-Position-In-
293 Response was non-present, a NULL pointer referece was performed.
297 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
298 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
299 now defined for all those error codes. So instead of putting 109 in
300 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
301 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
303 Modified the yaz-marcdump utility to skip garbage bytes between MARC
306 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
308 Program yaz-client now exits and produces an error message if multiple
309 Z39.50 servers are specified on the command line (none or one allowed
312 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
317 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
319 Fixed bug #272: Preserve spacing for CCL terms.
323 Added support for virtual hosts and multiple backend servers for
324 the YAZ frontend server. The configution is XML based and
325 support specificition of CQL to RPN mappings and explain information.
326 See section "Virtual Hosts" in the YAZ manual.
328 Extended OPAC display utility. OPAC display utility renders
329 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
330 to supplement yaz_marc_decode_wrbuf.
332 Fixed a bug in MARC decoder that could caused it to crash for some
333 invalid MARC records. More diagnostics and warnings where added in
334 XML output (warnings, etc are stored in comments).
336 --- 2.0.34 2005/02/08
338 Fixes for UNIX domain sockets. Bug #261.
340 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
342 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
343 Added yaz_marc_subfield_str which defines subfield lead string which is
344 used in YAZ_MARC_LINE format. Default string is blank+$. Added
345 yaz_marc_endline_str which defines end of fields string used in
346 YAZ_MARC_LINE format. Default string is newline.
348 Experimental support for MarcXChange. This format can be produced
349 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
350 http://www.bs.dk/standards/MarcXchange.xsd
352 Added yaz-client commands scansize that sets maximum number of
353 entries to be returned by scan.
355 --- 2.0.32 2005/01/11
357 Added support for SRW scan in yaz-client and Generic Frontend Server.
359 * Added whereInList member to SRW Scan Term.
361 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
363 Fixed NMEM system to return aligned blocks on the smallest boundaries
364 that are suitably aligned for all possible types on the particular
365 architecture YAZ is being built for.
367 --- 2.0.30 2005/01/04
369 Fixed numerious warnings that was issued with newer versions of GCC.
371 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
372 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
375 Make YAZ Generic Frontend Server slightly faster.
377 Enhance (and reduce) logging for Generic Frontend Server.
379 Revert YAZ log system so that it flushes every write operation
380 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
382 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
383 instead of LOG_, due to name clash with syslog(3). LOG_ are still
384 present. New applications should define YAZ_USE_NEW_LOG=1 - this
385 will effectively disable old definitions.
387 --- 2.0.28 2004/11/09
389 Added yaz_log_time_format which specifies log format using
392 Added yaz_log_module_level which returns mask for a module. Value
393 is non-zero mask a if module is enabled; zero if disabled.
395 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
396 in include/yaz/cql.h.
398 Fixed bug #176: Dont throw diagnostics on empty SRU args.
400 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
402 Fixed bug #172: RPM builds does not enable SSL.
404 Doxyfile.in part of dist. Doxyfile generated by configure.
406 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
407 are given and the corresponding component does not exist.
409 Extend CCL documentation in YAZ reference. Describe r=r.
411 --- 2.0.26 2004/10/01
413 Fixed MARC->MARCXML conversion to properly deal with
414 fields, subfields, indicators having non-ASCII characters.
416 Fixed MARC->MARCXML conversion so that ASCII control characters
417 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
420 Added YAZ GFS support for conversion from Z39.50 surrogate
421 diagnostics to SRW surrogate diagnostics.
423 Bug fix: YAZ GFS did not return schema in explainResponse.
425 --- 2.0.25 2004/09/30
427 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
428 now converts recordSchema to elementSetName as well as schema URI.
430 Fixed bug in COMSTACK that prevented HTTP request packages from being
433 --- 2.0.24 2004/09/29
435 Added CCL facility r=r "range" which is similar to r=o "ordered" but
436 does not require white-space before and after the dash in a range, e.g.
437 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
440 Fixed a few AC_TRY_LINK configure tests that did not operate properly
441 due to new GCC removing "redundant" code.
443 Added yaz-client commands scanpos and scanstep that sets preferred
444 position and step-size for scan.
446 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
448 Added CCL utility ccl_qual_buf which parses one or more CCL
449 spec lines in a buffer.
451 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
452 of name and value - ignoring empty lines and comments.
454 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
456 Added odr_get_element_path which returns current element path for an
457 ODR handle. This utility is useful in error handling or user-defined
460 Added ODR_PRINT utility odr_set_stream which is is a more generic
461 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
462 to a write function and pointer to close function. The close function - if
463 non-NULL - will be called during odr_destroy.
465 Fixed bug in CCL parser where truncation char was not removed from
466 right side when truncation=both was in effect.
468 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
471 --- 2.0.23 2004/08/11
473 Fix buffer overrun in CQL parser when dealing with proximity (%).
475 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
476 to UTF-8/UCS conversion is now only based on codetables.xml.
478 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
480 --- 2.0.22 2004/08/06
482 Add support for more "commit changes" in ZOOM (uses Extended Services).
484 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
487 Yet another small fix for configure of SSL.
489 --- 2.0.21 2004/05/14
491 Fix SSL libs for configure when --with-openssl=DIR is given.
493 --- 2.0.20 2004/05/10
495 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
497 SSL comstack now uses yaz.pem certificate file on server side
498 by default. Certificate filename can be configured by calling
499 comstack function cs_set_ssl_certificate_file before cs_bind is used.
501 Fix bug regarding multiple calls to ZOOM_connection_connect.
503 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
505 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
506 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
508 ZOOM now allows inspection of X509 peer certificate for verification.
509 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
511 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
512 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
513 as "modular" but it simplifies things.
515 Added cs_get_peer_certificate to that returns peer X509 PEM.
517 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
518 NULL if SSL is unavailable.
520 Documentation about MARC decoding tools.
522 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
524 --- 2.0.19 2004/03/30
526 Rename CHANGELOG to NEWS to follow GNU style packing.
528 Fix bug with missing initialization of member in init_diagnostics.
529 This bug affects threaded version of GFS server.
531 --- 2.0.18 2004/03/20
533 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
536 Ensure zlib.dll is packed with Windows install.
538 --- 2.0.17 2004/03/17
540 Fix encoding of xsd:string to use text instead of CDATA.
542 Fix endless loop in CQL parser with unbalanced ".
544 Use a more compact way to store MARC-8 conversion tables.
546 --- 2.0.16 2004/03/16 Debian only
548 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
551 Update CQL parser to use new CQL 1.1 modifiers for booleans and
556 --- 2.0.15 2004/03/01
558 Another fix for decoding of XML packed records.
560 --- 2.0.14 2004/02/25
562 Fixes for Chunked encoding. White space not ignored after length spec.
564 Update NS and use default NS for SRW diagnostic elements.
566 --- 2.0.13 2004/02/23
568 Implement ZOOM_resultset_cache_reset which resets record cache.
570 Implement ZOOM_resultset_sort which sorts a result set.
572 Implement chunked HTTP transfer.
574 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
576 --- 2.0.12 2004/02/16
578 Added member 'schema' to bend_explain_rr structure so that backend
579 can specify explain record identifier. Defaults to Zeerex 2.0.
581 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
583 --- 2.0.11 2004/02/16
585 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
588 Added init command for yaz-client which sends "extra" init request.
590 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
591 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
593 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
595 Make ZOOM error code for "invalid query".
597 Fixed compilation for SSL which wasn't properly enabled for all platforms.
599 --- 2.0.10 2004/02/05
601 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
604 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
606 Added option -p <file> to make Generic Frontend Server to write PID file.
608 Added option -D to put Generic Frontend Server in background on its own.
610 Make ZOOM C recognize option "password". If unset, "pass" is used
611 (for backwards compatibility).
613 Fixed a bug in Generic Frontend Server that could make it crash if a
614 client sets characterSetNegotation bit, but didn't pass negotiation stuff
617 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
618 Must be issued before open, in order to be in effect.
620 --- 2.0.9-6 2004/01/12 Debian/Windows
622 Make the SRU server more picky WRT unknown params, etc.
624 Bug fix: ZOOM scan response didn't return displayTerm - when present.
626 New YAZ client command, options, that sets Z39.50 options.
628 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
629 options from a string of tokens (one token for each option bit).
631 Update SRW diagnostic code messages.
633 --- 2.0.9-5 2004/01/07 Debian/Windows
635 Handle user defined stylesheet for SRW/SRU.
637 --- 2.0.9-4 2004/01/06 Debian/Windows
639 Fix bug in decoding of Content-Length.
641 --- 2.0.9-3 2004/01/06 Debian/Windows
643 Fix a bug with decoding of XML packed records.
645 --- 2.0.9-2 2004/01/05 Debian only
647 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
649 Fix bug in SRW/SRU diagnostics decoding.
653 Fixed bug in Generic Frontend Server which could drop records exceeding
654 preferred message size. Reported and fixed by Irina Dijour.
656 Fixed calculation of package size for structured records in Generic
657 Frontend Server. Reported and fixed by Irina Dijour.
659 Fixed namespace for SRW/SRU diagnostics.
661 Fixed SEGV in yaz-client that occured for HTTP connection errors.
665 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
666 this version is incompatible with version 1.0 and older YAZ SRW/SRU
669 CQL changes to reflect recent changes to the specification:
670 * Documentation talks about context sets instead of index sets.
671 * Documentation talks about indexes instead of qualifiers.
672 * The CQL-to-PQF transformer's configuration file now uses
673 "index.set.name = <attributes>" instead of the old form
674 "qualifier.set.name = <attributes>". (Both forms are still
675 understood but the latter is deprecated.)
676 * CQL terms with no explicit index specified are now interpreted as
677 cql.serverChoice instead of srw.serverChoice (which of course
678 behaves exactly the same.)
682 MARC conversion can now generate ISO2709 output in another
683 character set. yaz-marcdump uses this facility if you invoke it
686 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
687 functions from there can be used from C++.
691 Frontend server now transfers memory from decoded packages to stream
694 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
695 references to show up.
697 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
698 the ZOOM Abstract API. The older names for the same options are still
699 also supported for the benefit of old applications.
701 ZOOM-C supports "implementationId" and "implementationVersion" options
702 to go along with "implementationName". These allow the user code to
703 specify identification strings to be sent to servers.
704 Add OID for the new ExtLite attribute set.
706 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
707 as requested/supplid by Ere Maijala <ere@atp.fi>
709 For generic frontend server, reverse the order of
710 "toolkit-supplied / application-supplied" strings sent as implementationId,
711 Name and Version. Also, remove the spaces around the slash. This brings
712 the GFS in line with the behaviour of ZOOM-C on the client side.
714 Add function ZOOM_scanset_display_term.
716 yaz-client shows scan displayTerm if present.
718 Utility yaz-iconv is now installed by default along with the man page
721 Extend configure check for OpenSSL to use pkg-config where available (such
724 Incorporate patch by Morten Bogeskov which allows a Unix file socket
725 server to specify uid/gid/mask for socket using the format
726 unix:[user=uid,][group=gid,][umask=mask,]file=path
727 If file= is omitted the existing format is assumed, e.g.
729 in which case the mask is 0666 (rw for everybody).
731 Major restructure of YAZ source. All source in libyaz is in src directory.
732 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
733 util (utility programs such as ASN.1 compiler, yaz-marcdump).
735 Added man page for utility yaz-marcdump (used to be called marcdump).
736 yaz-marcdump is installed by 'make install'.
738 Fixed a memory leak in Generic Frontend Server that occurred when decoding
739 of incoming package failed.
741 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
743 Change prototype of odr_perror: add const to message string.
745 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
747 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
748 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
749 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
750 DNS lookup. There should not be any compatibility problems with this
751 assuming that blocking=1 or 0 is used.
753 Fix bad reference in UNIX comstack in function cs_addrstr.
755 Fix for compilation on AIX.
757 The generic front-end server (server/seshigh.c) now supports returning
758 Init diagnostics to the client in User-information-field, in
759 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
764 Allow any CQL relation (not just all,any,exact,scr).
766 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
767 that features the same UI.
769 Implemented command update0 in YAZ client which is equivalent to
770 update but uses old of Ext Update ASN.1.
772 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
773 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
774 Previously no OID was used for this info.
776 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
777 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
778 returns 'malformed search term' otherwise.
780 SortResponse member resultCount now set to NULL in sort handler of
783 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
786 Add three new utility functions for translating OIDs between various
787 formats -- symbolic name such as "Usmarc", minus-1-terminated int
788 arrays and dotted strings such as "1.2.840.10003.9.5.1":
789 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
790 char *oid_to_dotstring(const int *oid, char *oidbuf);
791 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
793 Reverted modifications for ES Update definition for z_IU0Update
794 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
795 is back to YAZ 2.0.2.
797 String value attributes for CCL parser.
799 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
800 which their FirstSearch server returns in Init responses, sometimes
801 carrying useful diagnostic information when Init fails. This has the
802 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
803 "z39.50/oclcui.asn", where its definition is somewhat different from
804 what OCLC document on their web-site, as required to interoperate with
807 Support for anonymous authentication in yaz-client. Use the command
810 * Fix the OID of the Index Data-local "admin" Extended Service from
811 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
812 the 1000, which indicates a locally-defined OID, was a mistake.
816 Fix CCL directive @case handling so that it affects string match for
817 both CCL keywords and qualifiers.
819 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
820 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
821 Decoder has been updated with ASN.1 changes as listed in
822 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
823 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
824 z_IUUpdate, remains unchanged.
826 ZOOM_record_get may now return a record in a specific character set.
827 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
828 "from" is the character set of record as returned by target. "to" is
829 the character set to be returned. If omitted, "to" is UTF-8.
831 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
833 New ODR utility, odr_getelement, which returns name of element for
834 which encoding/decoding failed.
836 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
837 in cases where a required element was omitted.
839 Bug fix: some MARC8 sequences were not converted.
841 New ZOOM option "step" which specifies number of records to be
842 retrieved in one chunk. Used in conjunction with "start" and "count".
844 SRW support for yaz-client. Use scheme http: to use it, e.g.
847 yaz-client no longer does (un)intelligent character set conversions
848 by default. Can be enabled with charset and marc_charset commands.
850 xmalloc trace fix for 64-bit systems such as DEC alpha.
852 Solaris 2.6 compile fix.
854 New function, cql_strerror() translates SRW error codes, as returned
855 by cql_transform_error(), into human-readable English strings. Used
856 in yaz-client diagnostics when appropriate.
858 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
859 converts it into a type-1 query which is sent to the server. This
860 makes CQL available for use with all Z-servers, as opposed to the tiny
861 minority that can handle CQL queries themselves.
865 New Debian package layout similar to the Redhat Package layout.
867 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
868 and search result respectively.
872 Redhat package is now several packages: libyaz (runtime libraries),
873 libyaz-devel (development and documentation, and yaz (utility programs).
874 Package spec file by Morten Bøgeskov.
876 New member 'schema' in struct bend_fetch_rr which the name of requested
877 schema (SRW/SRU) for record (or NULL if none was given). The fetch
878 handler MAY set this to reflect the schema of the returned record.
880 New member 'display_term' in struct scan_entry. GFS now sets member entries
881 and allocates scan entries to be filled by user scan handler. In previous
882 version, entries member was allocated by the scan handler. That still works,
883 but the GFS will ignore member display_term - assuming it was NOT set by
884 the handler. The fact that the GFS now allocates the entries both allows
885 for new members and makes a scan handler easier to write.
887 Fix CQL lex buffer overflow.
889 SRW/SRU recordPacking. For SRW default recordPacking is string. For
890 SRU default recordPacking is string.
892 SRU protocol support for frontend server.
894 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
896 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
898 Added scan for the ZOOM shell (zoomsh).
902 * String Identifers for Schemas (Amendment 5).
903 http://lcweb.loc.gov/z3950/agency/amend/am5.html
904 Old definition for schema
905 Odr_oid *schema; /* OPT */
910 Z_InternationalString *uri;
911 #define Z_Schema_oid 1
912 #define Z_Schema_uri 2
915 * resultCount parameter to Sort Response (Amendment 1).
916 http://lcweb.loc.gov/z3950/agency/amend/am1.html
918 Support for SRW 1.0 over HTTP. This is an optional feature and
919 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
922 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
923 on the same port. SRW SearchRetrieveRequests are mapped
924 to bend_init,bend_search,bend_fetch,bend_close.
926 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
928 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
929 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
931 ZOOM connections are SRW based if schem http is used for hostname
932 in connect, e.g. z = ZOOM_connection_new("http://myserver");
933 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
935 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
936 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
937 distance=n, order=true/false, relation=le, prox unit=word. If
938 n is omitted, distance 1 is used.
940 Fixed problem with C compiler include path in wrong order.
942 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
943 on Solaris. Patch from Ko van der Sloot.
945 New MARC decode API. All new functions operate on a yaz_marc_t
946 handle. The most important new functions are: yaz_marc_create,
947 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
948 decode and destroy respectively. Decoder can produce formats
949 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
950 include/yaz/marcdisp.h.
952 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
953 to UTF-8, UCS-32, wchar_t or Latin-1.
955 * Prototypes for yaz_iconv_-functions moved to separate header
956 include/yaz/yaz-iconv.h.
958 Make a few private functions 'static' in unix.c. This prevents
959 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
961 For ZOOM connection, the options targetImplementation{Id,Name,Version}
962 are set when Init Response is received.
964 New function ZOOM_connection_error_x similar to ZOOM_connection_error
965 but returns diagnostic set as well.
967 New function yaz_strerror which is a portable wrapper for
968 strerror/strerror_r/GetLastMessage.
970 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
971 is returned for MARC. If type is "oai", then OAI MARC is returned.
973 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
978 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
980 Fix bad race conditions on SIGTERM and terminate gracefully in
983 Move retrieval (data1) module to Zebra since nobody seems to be
986 Add GRS-1 render for ZOOM using same format as yaz-client.
990 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
992 Fix broken ESpec handling in data1 module.
994 SGML reader parses comments and makes them part of the data1 tree.
996 Added several type casts so that YAZ compiles as C++ code.
998 ZOOM didn't handle PDU encoding failures properly.
1000 Added more Bib-1 diagnostics (approved extensions).
1002 GNU configure: better check for iconv.
1004 More portable use of accept, getpeername. Check for socklen_t. Use
1005 int/size_t if socklen_t is not defined.
1009 PQF parser rejects bad queries - including those with extra
1010 characters in them. PQF parser used to silently ignore that.
1011 Cleaner API for PQF added, which allows you to get detailed
1012 error information for bad queries (see yaz/pquery.h).
1014 Fixed bug in ZOOM_record_get for type "database".
1016 Implemented mini iconv library supporting conversions between
1017 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1019 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1021 --- 1.8.9 2002/08/20
1023 Fixed ZOOM C record cache so that preferredRecordSyntax and
1024 elementSetName is used to check for already fetched records.
1026 --- 1.8.8 2002/08/02
1028 Added three members in bend_initrequest structure to facilitate
1029 character set negotiation.
1031 Fixed a bug in frontend server that could cause indefinite
1032 loops under rare conditions.
1034 Revised character set utilities (charneg.h) so that encoding
1035 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1037 For PQF, directive @term <type> sets term type for Scan/Search.
1038 Here <type> is general, string, numeric, null. The term type
1039 is inherited - just like @attr.
1041 New call odr_set_charset that sets character set conversion for
1042 international-strings on a ODR stream. Prototype is:
1043 int odr_set_charset(ODR o, const char *to, const char *from);
1044 The InternationalString is still represented as C string in YAZ
1045 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1046 won't). On the protocol level, you can use any encoding.
1048 Support for UNIX sockets in ZOOM.
1050 Solaris recv sometimes returns errno == ENOENT. It is treated as
1051 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1053 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1054 both client and server. Code by Morten Bøgeskov.
1056 --- 1.8.7 2002/05/22
1058 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1059 that they can be used directly from Visual Basic. You must recompile
1060 your windows APP if you're using ZOOM.
1062 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1063 Commands "lang" and "charset" sets language and character set respectively.
1064 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1065 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1067 Attributes from multiple CCL fields may be OR'ed rather than merged
1068 using directive "@field or". Fields are still merged by default -
1069 equivalent to "@field merge".
1071 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1074 Fixed bug in zget for parameter ExtendedServicesResponse.
1078 --- 1.8.6 2002/03/25
1080 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1082 Client displays USR.1:SearchResult-1 (hits per term).
1084 Additional Search Info for search in Generic Frontend Server.
1086 Fixed CCL parsing of "field=s".
1088 WIN32 installer - using the excellent NSIS software from nullsoft.
1090 Fixed CCL parsing of "field = - <number>".
1092 Added function yaz_marc_decode that decodes MARC for line mode
1093 display or XML (similar to that used by JZKit).
1095 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1096 Z39.50. But ISO/ILL was, however.
1098 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1099 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1101 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1102 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1104 --- 1.8.5 2002/02/03
1106 New YAZ client features: Command completion and new commands:
1107 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1108 Code provided by Jacob Poulsen.
1110 New call oid_trav, that visits all registered OIDs via callback.
1112 Function ZOOM_record_get now returns const char pointer rather than
1113 void pointer. It saves a lot of type casts.
1115 For YAZ client, command "auth" now allows you to set authentication
1116 in IdPass style. It is enabled when three tokens are given - order
1117 is user, group and password.
1119 Fix memory leaks in MARC record handling for ZOOM.
1121 New option for YAZ client, -k <kilobytes> that sets
1122 maximum record size. Similar to -k option for generic frontend
1123 server and yaz-ztest.
1125 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1127 Prefix query parser reports "fail" when bad attribute set is given.
1129 Fix in MARC decoder. Proximity logging. Fix for attribute set
1130 in scan handler for server. Patches by Shigeru Ishida.
1132 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1135 Configure option --with-openssl=<dir> now works when a directory is
1136 specified. Patch provided by Morten Bøgeskov.
1138 New option for YAZ client, -u <auth>, that sets authentication.
1140 ZOOM fix: error information was sometimes "missing", since error
1141 was cleared/reset too when it shouldn't.
1143 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1145 --- 1.8.4 2002/01/04
1147 Scan for ZOOM API. New object ZOOM_scanset. New functions
1148 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1149 ZOOM_scanset_destroy.
1151 New ZOOM function, ZOOM_connection_last_event, that returns type
1152 of last event (such as "receive data", "send data", "apdu received",
1155 New ZOOM option, schema, that specifies schema for retrieval.
1157 New CCL feature. Qualifiers can be aliases for one or more
1158 other qualifiers (if more than one is given, OR is used).
1160 ZOOM uses named result sets if target supports it.
1162 Two new YAZ client commands: . (dot, which sources a script of YAZ
1163 client commands), and ! (to execute shell command.). Implemented
1166 Working on Debian packages.
1168 --- 1.8.3 2001/11/19
1170 YAZ client enables named result sets only if target supports it.
1172 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1174 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1175 with key="host" to get same result.
1177 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1178 Function Z3950_resultset_record(s) returns references to records
1179 "owned" by resultset. To become owner use Z3950_record_clone.
1181 Function z_ext_record handles Extended Services. Thanks to
1184 --- 1.8.2 2001/11/12
1186 CCL Parser fix: ignore token comma when dealing with and-lists.
1188 Documentation updates for COMSTACK.
1190 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1191 Changed prototype Z3950_records. For some functions, int parameters
1192 were changed to size_t.
1194 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1197 New MARC decode/display function, marc_display_exl, which properly rejects
1198 non-ISO2709 records. YAZ client uses it.
1200 --- 1.8.1 2001/10/29
1202 Fix bug: local attribute set wasn't set correctly in PQF strings.
1206 * Old Z39.50 codecs no longer supported.
1208 Added ZOOM C binding. See http://zoom.z3950.org/
1210 Renamed states for COMSTACKs to avoid confusion with events.
1212 Implemented cs_look and proper cs_rcvconnect.
1214 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1216 Configure detects POSIX threads on OpenBSD.
1218 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1219 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1221 When error is returned from present handler, non-surrogate diagnostic
1222 is returned in present response (and fetch handler is no longer called).
1224 * Minor adjustments to pquery parser (PQF). Token characters may be
1225 escaped by using backslash (C-style).
1227 PQF parser allows string attribute values to be specified. For @attr,
1228 non-numeric characters after the equal-sign are treated as strings
1229 (e.g. @attr 9=title).
1231 CCL trunction character may be defined (@truncation in file)
1233 * function zget_ExtendedServicesRequest sets waitAction to
1234 waitIfPossible (was wait).
1236 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1239 CCL operator names may be set in field definition files (CCL_bibset).
1240 See ccl/bib1 for an example.
1242 Fixes in ASN.1 compiler for C++ compatibility.
1244 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1245 and "op_or" to avoid conflict with C++.
1247 Fixed problem with GNU readline detection on Redhat 7.0.
1249 Added step-size for Scan backend handler.
1251 Fixed bug that made the frontend server crash when no attribute
1252 set was specified for scan.
1254 Front-end server automatically switches to original working directory
1255 when installed as an NT service. Previously -w had to be specified to
1258 Added extended attributes for retrieval module (data1), so that data1
1259 records carry d1_readXML/SGML attributes. d1_read also supports
1260 null-data rules ( <tag/>)
1262 On UNIX when POSIX threads are available, a separate library libyazthread
1263 is created. Programmers should link with that library and the yaz library
1264 when using threads. The reason for the split was that some applications
1265 on Linux, such as Apache, doesn't work well when using shared objects that
1268 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1269 (or any frontend server) in SSL mode by specifying ssl: followed by
1270 address. Only tested on UNIX.
1272 Added feature for CCL module. Virtual structure s=al or s=ol generates
1273 and-list and or-list respectively instead of phrase search.
1277 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1278 log_mask_str. This was done to avoid name conflicts with other libraries
1279 (such as other PHP extensions).
1281 Added raw OID member for preferred record syntax (request_format_raw)
1282 and returned record syntax (output_format_raw) for backend fetch method.
1284 Config file yaz-config now accepts options so that it returns specific
1285 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1287 Shared library support for UNIX using GNU libtool.
1289 * Modified backend interface. Request/Response struct's replaced by
1290 one read/write C struct. For example bend_fetchrequest and
1291 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1292 Every handler - even search has to be registered in bend_init
1293 handler. This means that the YAZ library no longer refers to
1294 external functions and it makes it possible to make the whole
1295 thing a single DLL/SO.
1297 Added Segment handler for backend server.
1299 Added Zmbol/Zebra administrative functions to YAZ client.
1301 Threaded frontend server on UNIX (when POSIX Threads are available).
1302 Starting the server with option -T enables multi-threading.
1306 Added configure option --enable-comp/disable-comp to control use
1307 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1308 located in sub directory asn.
1310 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1311 in ${exec_prefix}/bin along with the other programs yaz-client and
1314 GNU automake used to maintain makefiles.
1316 Added several OID's.
1318 Changed retrieval module so that we can load records with no abstract
1319 syntax defined. Tagpaths in these records are fully composed of string
1322 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1326 On UNIX, the generated makefile now supports a proper 'make install'.
1327 The prefix can be set via GNU configure to set the install location
1328 (default is /usr/local).
1330 * YAZ programs client and ztest were renamed to yaz-client and
1331 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1332 locations, such as /usr/bin,/usr/local/bin,etc.
1334 * YAZ Header files were moved from include to include/yaz. YAZ Header
1335 files are referred to as include <yaz/log.h> rather than <log.h>.
1336 The YAZ include path (-I ..) is therefore the same as before. Programmers
1337 should update their #include statements or use -Ipath/include/yaz
1338 instead. The main motivation for doing this change is that YAZ header files
1339 can be installed in "standard" locations /usr/include,/usr/local/include
1340 without introducing conflicts, since ALL YAZ header files are stored
1341 in subdirectory yaz (under /usr/include for example).
1343 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1344 rather than project/workspace files. We switched because project files
1345 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1348 Changed name of logging function, logf, to yaz_log, to prevent name
1349 clash with some math-log functions. The YAZ header log.h defines logf
1350 to yaz_log (#define) so there should be no incompatibilities by this
1353 Added bend_start/bend_stop handlers for server. These handler are
1354 called on start/stop of server. For windows they are called whenever
1355 a service is started/stopped.
1357 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1358 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1359 in util/yc.tcl. The auto-generated C code structures are, in a few
1360 cases, incompatible with the old decoders. There are differences in the
1361 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1362 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1363 The preprocessor variable ASN_COMPILED is defined when the compiled
1364 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1365 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1366 wish to use the old encoders/decoders you can specify --disable-yc
1369 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1370 version so that it supports both new - and old version of DB Update
1372 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1373 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1374 change. The name parameter can be set to 0 in which no name is specified
1375 for the construction. The macros odr_implicit and odr_explicit sets name
1376 parameter to zero for the construction involved. New macros
1377 odr_implicit_tag and odr_explicit_tag are similar to the others,
1378 except that a name parameter is added. For programmers' that don't use
1379 ODR they probably only need to change the call to z_APDU and z_External.
1381 Added access control facility by interfacing the TCP wrapper library.
1382 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1383 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1384 name of the daemon and enables the access control as specified in
1385 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1387 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1388 den Dool <H.M.vdnDool@kub.nl>.
1390 Added reference ID parameter to most functions in server API - refer
1391 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1393 Changed name of ccl library to libccl.a (was ccl.a).
1395 Fixed bug in decoder for Explain (Category TargetInfo).
1397 Added support for GNU readline in client. Thanks to Jacob Poulsen
1398 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1400 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1401 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1402 IMPLEMENTATION! This change was made to the development version before
1403 the ZIG decided to retract the amendment. If any users MUST be
1404 compatible with the original Update definition, PLEASE CONTACT US, and
1405 we will include a separate definition corresponding to the old Update
1406 ES. Note that because of the change to the ASN.1 of the
1407 TaskPackageRecordStructure we cannot define a single structure that
1408 will support both versions.
1410 * Added const modifier to buffer parameter for some ODR/BER encoding
1411 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1412 completeWAIS, odr_dumpBER.
1414 Fixed bug in client.c which caused a crash when a scanResponse didn't
1415 contain positionOfTerm.
1417 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1418 * will cause an error in a client if a non-YAZ target sends both a
1419 * list of Scan entries and non-surrogate diagnostics.
1421 Retrieval module enhancements. Tag sets may be typed in the reference
1422 to it. From the .abs-file the "tagset" directive takes a third optional
1423 integer type for the tag set referenced. From a .tag-file the "include"
1424 directive takes a third optional type as well. The old "type" directive
1425 in the tag set itself is still recognized but acts as the default type
1428 Backend interface change. Individual Scan terms returned from bend_scan
1429 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1430 in include/backend.h.
1432 Retrieval module enhancements. Multiple tag sets and attribute sets may
1433 be specified in abstract syntax specs. Revised the error/warning for
1434 logging messages reported by the retrieval module when reading the
1437 Object Identifier system (oid_..) changed. The API is backwards
1438 compatible but the oid-routines now allocates new OID's when needed.
1439 Raw OID's may be specified in oid_getvalbyname.
1441 YAZ now uses GNU configure to generate Makefile(s).
1443 * Minor changes in some of the member names of DeleteResultSetRequest and
1444 DeleteResultSetResponse. See include/proto.h.
1446 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1447 and added member 'languages' in TargetInfo (which was missing).
1449 Changed the way attribute sets are handled in the retrieval
1450 module. These are now cached, just like the abstract syntaxes
1453 Changed YAZ so that it links with compiled ASN.1.
1455 Added Explain-schema definitions and mapping routines. The following
1456 Explain categories have been implemented: AttributeDetails,
1457 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1459 Fixed minor bug in Windows version of Server Library.
1461 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1463 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1465 Added EXTERNAL: UNIverse Resource Report (non-standard).
1467 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1468 ENUMERATED and SET OF.
1470 * Added 'const' to some of the char pointer arguments for the
1471 functions, data1_read_node, data1_getelementbytagname,
1472 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1475 Fixed bug in data1_insert_taggeddata - the last_child member of
1476 parent wasn't initialised.
1478 * Changed data1_read_record and data1_read_node so that the supplied
1479 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1480 doesn't refer to any parts of the "SGML"-buffer.
1482 Fixed bug in server library (Windows version of statserv_remove).
1484 * Changed code so that it compiles as C++. The type definition
1485 of Odr_fun which is a member of Odr_arm was changed. The result is,
1486 that an explicit typecast is needed for the fun pointer when
1487 using Odr_arm - as in:
1488 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1490 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1492 Implemented the new structured date and time definition as approved
1493 by the ZIG. Added schemaId element to the specificTag in Espec-1
1494 (also approved at the last ZIG). Thanks to RVDM.
1496 Added some Object identifiers (RVDM).
1498 Changed the Update Extended Service (RVDM).
1500 Added command "refid" to client which specifies referenceId for
1501 the following requests.
1503 Implemented extended service handling for server. See ztest.c
1504 for an example as well as backend.h. New handlers are registerd
1505 in the Init handler.
1507 * Changed interface for sort in server.
1509 Added new members to statserv_options_block. It allows a server
1510 to read options from another source than just the command line. Thanks
1511 to Charles Woodfield.
1513 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1514 renamed to zboolean. Some C++ compilers complained about the name.
1516 Minor changes to gils.abs. Added index 's' (sort) on title
1517 and date/time-last-modified.
1519 --- 1.4pl2 1998/1/30
1521 Fixed bug in server library regarding inetd mode (-i). This bug
1522 was introduced by release 1.4.
1524 --- 1.4pl1 1998/1/29
1526 Added sort facility in client and backend server interface.
1528 Fixed problem with dependencies in Makefile(s).
1530 Fixed bugs for encoders/decoders of extended services and
1533 Implemented sub-tree feature for schemas. Sub-trees are
1534 referenced in *.abs-files. See explain.abs for an example
1535 of the use of this feature.
1537 Modified bib1.att; local attributes for ANY didn't include
1538 ANY itself (only affects use of the retrieval module).
1540 Fixed bug in plain SGML reader in function data1_read_node:
1541 tags with prefix "var" was incorrectly interpreted as variants.
1543 Added feature "sub-schemas" to enable references to - and definitions
1544 of - group of elements.
1546 * Removed member parent from type data1_element (in data1.h).
1548 Implemented function odr_nullval() that returns the value of
1551 * Removed member num_children from data1_node (in data1.h).
1553 Made NT service interface part of the server library. The
1554 function statserv_main uses the NT service when required and
1555 calls the statserv_start / statserv_close routines.
1557 Routine zget_SearchRequest and zget_PresentRequest fills
1558 resultSetName/Id member with "default" instead of "Default".
1560 Fixed memory leak in server. Request queue member wasn't freed.
1562 Fixed nmem_exit so that memory is freed.
1566 Revised the CCL parser utility to be thread safe.
1568 Added function, oid_ent_to_oid, to replace the function
1569 oid_getoidbyent, which is not thread safe.
1571 * Added nmem_init and nmem_exit to initialize and release
1572 NMEM resources. Function nmem_init should be called once in the
1573 initial thread before NMEM/ODR is used. statserv.c and client.c
1574 have been changed accordingly. The change was necessary to make
1575 NMEM thread safe. The NMEM memory pool is shared amongst threads
1576 in a process. Unix-based applications will still work fine without
1579 Added NT Services interface for the the Z39.50 (statserv) Server.
1580 Refer to the ztest.c source on the usage.
1582 Windows 95/NT port using MSVC5.0. Project files are included in the
1585 * Defined new 'global' handle for the retrieval (data1) system. The
1586 new handled, data1_handle, describes the state of the data1 system.
1587 This handle is passed as first argument to virtually all
1588 data1 related routines. The functions data1_create and data1_destroy
1589 creates and destroys a data1 handle respectively.
1591 Added ODR encode stream member to all backend request structures
1592 init, search, scan etc. This stream should be used to allocate all
1593 memory used for the response when thread safe operation is needed.
1595 Changed the comstack utility, cs_addstr, to be thread safe. The
1596 returned hostname string returned by the function is now part the
1599 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1600 function. The cs_straddr takes a COMSTACK handle as argument, so this
1601 function must be used after cs_create and before bind/connect.
1602 This function is thread safe.
1604 Moved test server to 'ztest' directory - generic server code still
1605 in 'server' directory.
1607 Made prefix query (pquery.c) utility thread safe.
1609 Added new function modifier YAZ_EXPORT to 'export' public DLL
1610 functions when using windows (see include/yconfig.h).
1612 Added definitions to the OID database (util/oid.c) (RVDM).
1614 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1616 Added call to ccl_rpn_delete in client program.
1618 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1619 release of RPN structure.
1621 Added support for C++, headers uses extern "C" for public definitions.
1622 With input from RVDM.
1624 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1625 Thanks to Ronald van der Meer (RVDM).
1627 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1629 Added support for private extensions to the OID database
1630 (oid_setprivateoids()). Thanks to RVDM.
1632 Added optional, physical ANY (key replication)
1634 Fixed null-reference problem in GRS-1 output filter.
1636 Proximity operator added to Prefix Query Format (PQF).
1638 In test client command "base" accepts multiple databases.
1640 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1644 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1646 Smallish bug-fixes in the new encoders/decoders (explain).
1648 Bug fixed in DeleteRequest.
1650 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1652 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1654 Added SOIF syntax (using private OID for now) to retrieval module and client.
1656 Added Update extended service.
1658 Added SearchResult-1 additional info structure.
1660 Added optional CCL (ISO8777) interpreter as separate module. Available
1663 --- 1.2 1996/6/10 (1st anniversary release)
1665 Added Summary record syntax. Lightly tested.
1667 Added OPAC record syntax. Untested.
1669 Added ResourceReport service encoders/decoders. Untested.
1671 Fixed bug in z_Unit - wrong tagging on unitSystem.
1673 Fixed bug in the DiagRecs decoder.
1675 Added options for max PDU size and session timeout to frontend-server.
1677 Added documentation of query-language parsers and other supporting utilities.
1679 [frontend-server] Added Attribute set to the bend_scanrequest API.
1681 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1682 surrogate diagnostics were generated.
1684 [retrieval] Allow multiple local values for attribute.
1686 [retrieval] Allow multiple attributes per element in .abs files. index type.
1688 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1690 --- 1.1pl2 1996/4/10
1692 Minor changes, mostly specific to Zebra's requirements (retrieval)
1696 Repaired bug in frontend server when running multiple listening
1697 endpoints in dynamic mode.
1699 z_External() now won't break if a known, ASN.1 value comes encapsulated
1700 in an octet-string. The value will pass through unmodified in an Odr_oct.
1702 Added a bit of code to the demo client to decode & display
1703 ASN.1-structured records represented in the octet-aligned branch of
1704 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1706 Added z_ext_getentbyref() to the ASN module. Doc updated.
1708 * Completed the SCAN definition in the ASN module. This may break SCAN
1709 code based on older YAZ-versions at compile-time. The fix is easy -
1712 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1713 under the SCAN definition. Remember to initialize this, server-people.
1715 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1716 that this does not extend to ODR and ASN.
1718 Comstack allows insertion of established socket (primarily for
1719 inetd-operation of servers). Doc updated.
1721 Front-end server can now start from the inetd in TCP mode. Doc
1724 --- 1.0pl4 1996/1/24
1728 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1729 the rank and record number.
1731 Adjustments to the frontend server.
1733 Fixed diagnostic BER dumper. It ignored the file argument.
1737 Various changes to retrieval module.
1739 Changed the union discriminators of the protocol files from enums to
1740 ints paired with #defines.
1742 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1745 *Changed operator in the RPN structure to 'roperator', again to avoid a
1748 Fixed problems in Explain decoders/encoders.
1750 --- 1.0pl2 1995/12/6
1752 Memory bug in log module fixed.
1754 --- 1.0pl1 1995/12/5
1756 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1758 Bug in Explain DatabaseInfo module fixed.
1760 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1764 The shift to v1.0 signals that we now consider the *core* functionality
1765 of YAZ reasonably stable (the core being more or less equivalent to
1766 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1767 tested (Explain not at all - though that will happen soonish).
1769 Minor changes to code to support Windows port.
1771 Various minor changes after we're getting to use GRS-1 & co. more.
1773 Added Espec-1 format.
1775 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1776 of the protocol and it cannot be selected when encoding (maps into 'string'
1777 when decoding). Needed to talk to some servers.
1779 Demo client can request simple element set names.
1781 Added Diagnostic Format encoders/decoders.
1783 Added simple Close handling to frontend server (no hooks for resource
1784 reporting yet), and demonstration client.
1786 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1788 --- 1.0b3 1995/08/24
1790 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1791 handled incorrectly when records were requested in the searchResponse. This
1792 will only affect you if you use the frontend-server.
1794 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1795 Test-client will ask for and print GRS1. Ztest will return dummy records
1798 Added Explain encoders/decoders to the service-level API. Untested.
1800 Added Extended Services: Item Order encoders and decoders to the Service-
1801 level API. Untested. We could use a recent copy of the pertinent bits
1802 of the ILL protocol to add those bits.
1804 Added diagnostic format 1 encoders/decoders to the service-level API.
1807 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1808 odr_cons.c, which causes a more correct output.
1810 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1811 was always set to 0 when no records were requested in the searchRequest.
1813 * Added better external-handling. This shouldn't harm old code that
1814 *encodes* externals. It can break code that looks for a
1815 'single-ASN1-type' representation, since those types that are known
1816 are now decoded immediately. Look at the SUTRS sample code in
1817 seshigh.c and client.c. Documentation updated.
1819 Handling of structured records in bend_fetchresponse. Length -1 marks
1820 structured record, type is deduced from format field.
1822 --- 1.0b2 1995/06/27
1823 Fairly quick maintenance release to add SUTRS support.
1825 Fixed handling of SUTRS records in the demonstration client.
1827 * Added format field to the bend_fetchrequest and bend_fetchresponce
1828 structures of the backend API (frontend server). When the record is
1829 returned, the value of the format field is mapped to an OID. The
1830 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1831 of the record. The special value VAL_NONE in the bend_request means
1832 that no specific format was requested by the client. Documentation
1833 updated accordingly. Test server (ztest) will return a fixed dummy
1834 SUTRS record if your client requests SUTRS.
1836 Documentation updated accordingly.
1838 You can now set external libraries and RANLIB support in the top-level
1842 First public release.
