1 Added HTTP tunnel facility for COMSTACK, bug #1752.
2 This is a facility that allows a Web proxy, such as squid, to tunnel
3 Z39.50 traffic. This facility is "transparent" to must applications
4 using YAZ. It's enabled by using pseudo transport connect: followed bý
5 the we proxy address, followed by command, then follwed by he regular
6 "virtual" addresss. For example,
7 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
11 Fixed bad memory reference in ZOOM_record - cuased by member not being
12 initialized. This was a problem only in YAZ 3.0.12.
14 Fixed bug in conversion from MARC to XML: Non-XML characters in control
15 fields were not removed.
17 Changed the way C code is generated from codetables.xml. Made a MARC-8
18 conversion trie for each characterSet section rather than codeTable.
19 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
20 of codetables.xml from Larry Dixson, LOC. Bug #1464.
24 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
25 from ZOOM_record_error).
27 ZOOM C function ZOOM_record_get returns record schema for type="schema".
29 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
31 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
33 Better SRW-to-Bib-1 diagnostic mapping.
35 ZOOM C and yaz-client announces SRU version 1.2 by default.
37 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
40 Fixed in yaz_sru_decode to allow other version than 1.1.
44 Added support for SRU scan for ZOOM.
46 Added support for the use of the older versions or Extended Service
47 Update in ZOOM. To faciliate this, an option "updateVersion" may be
48 set to the version , 1=first, 2=second, 3=third. The third version is
49 what ZOOM C has used so far. And that, obviously, is the default.
51 Added support for CCL queries in Z39.50 queries sent to the GFS (and
52 therefore in Zebra and in SimpleServer-based applications). The new
53 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
54 qualifier file used to transform incoming CCL queries into Type-1 RPN,
55 which is passed into the back-end search callback function.
57 Added support for HTTP Basic authentication in clients: the SRU/W
58 codec encodes the username/password elements of the PDU structure
59 appropriately, and these may be set using the "user" and "password"
60 options in ZOOM-C applications (the same options that are used for
61 Z39.50 authentication).
65 Fixed bug #1208: SSL appears to be broken in ZOOM.
67 Fixed bug #1206: Libxml2 include path weirdness.
69 Added oid_name_to_dotstring.
71 Allow elementSetName to be specified for ZOOM C record update.
73 Allow waitAction to be specified for ZOOM C based for Extended Services.
75 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
76 syntax OID. Bug introduced in YAZ 3 series.
78 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
82 Fixed bug #1157: yaz-client does not read .yazclientrc from current
83 directory. yaz-client now reads commands from file given by option -f
84 if specified; then tries to read .yazclientrc in current directory.
85 Failing that, it reads .yazclientrc from user's home directory.
87 Added support for correlationInfo Note and ID for Record Update via
90 Added yaz-client command querycharset which specifies character set for
91 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
92 (termListAndStartPoint).
94 Charset ISO5428:1984 is an alias for ISO5428-1984.
96 Implemented a way to perform scan in a result set using Z39.50. This
97 is achieved by attaching the result set name in the characterInfo
98 (type InternationalString) of OtherInformation in the Scan Request PDU.
99 The result set is identified in the otherinformation by the new OID:
100 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
101 This allows for scan in result set and faceted search . Zebra did some
102 of this in the APT term using attribute type 8 and value being result
103 set. Using the OtherInformation approach for this is cleaner and easier
104 to work with in proxies and the like. This facility can be used in
105 yaz-client using new command setscan which takes a result set as first
106 argument, start position (APT) as second.
108 Changed decoding of SRU XML packed records to deal with servers that
109 have recordData with XML data with multiple root nodes. Also make
110 comparison for recordPacking case insensitive. Again, one server
111 returns "XML" where others return "xml".
113 For SRU responses allow Content-Type application/xml as well as text/xml.
117 Fixed bug in character set conversion of BER strings. Bug introduced
122 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
124 For OID class, use oid_class consistently.
126 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
129 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
130 character set for bibliographic information interchange". By Giannis Kosmas.
132 Added documentation on new OID API.
136 Changes to generic frontend server interface: added new member
137 'query_charset' for bend_initrequest structure. A backend init handler
138 should set this member to its native character set for query terms.
139 When defined, the frontend server logic will announce this character set
140 to a client if the negotiationModel bit is set by the client. All server
141 implementors are encouraged to specify this. If a backend server does not
142 specify this a warning is issued using yaz_log(YLOG_WARN,..).
144 Added CCL utility to remove terms (stop words) from resulting RPN
145 tree. This is handled by functions with prefix ccl_stop_words_ .
147 New ZOOM C option, "rpnCharset", which allows client-side conversion of
148 terms in RPN queries.
150 Clean-up the CCL API. Moved some internal structures from ccl.h to
151 private header cclp.h. Changed ccl_parser_create so that a Bibset must
152 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
153 This is replaced by ccl_parser_find_str which takes a string instead.
155 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
156 libyaz.la is the core of YAZ except the generic frontend server and
157 does not depend on POSIX threads anymore. libyaz_server.la is the
158 generic frontend server facilities and uses POSIX thread functionality
159 if available. The libyaz.la no longer depends on POSIX threads because
160 the number of global structures is limited. NMEM no longer re-uses blocks
161 between threads ; it simply free's memory immediately but allocates in
162 "large" chunks as usual. We don't expect any performance penalties
163 because of this. The yaz_log system is still using a global log_level so
164 caution must be taken when modifying it with yaz_log_init_.. +
165 yaz_log_mask_str. This, however, should not cause any trouble because
166 these functions are called during initialization of application code
167 anyway. `yaz-config --libs server` returns libs for server applications;
168 `yaz-config --libs` returns libs for non-server applications.
170 New OID database - with public definitions in oid_db.h. Removed old OID
171 database including the head oid.h and definitions such as enum oid_value
172 and struct oident. The new OID database uses the same string names as
173 before but the 'protocol' is gone. There are now only two representations
174 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
175 converts from string to OID; functions with prefix yaz_oid_to_string
176 converts the other way.
178 Change to emit_term() in CQL-to-PQF query translation: when a term has
179 the /regexp relation modifier, do not process it for leading and
180 trailing "^" and "*", which have quite different meanings in regular
183 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
184 write handlers no longer carries a 'last' parameter. This will make
185 yaz_iconv flush "less" characters. A flush is performed by call to
186 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
188 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
189 removed, because function yaz_query_to_wrbuf does the same.
191 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
192 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
194 Deprecated MARC utility functions removed.
196 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
199 Branch split: YAZ_2_1_55_branch
201 --- 2.1.54 2007/03/16
203 Fix to ZOOM-C so that transparent reconnection is properly handled on
204 connections that are in asynchronous mode.
206 Fixed compilation on OpenBSD 4.0.
208 Large strings in GRS-1 records are now properly displayed in yaz-client.
210 Added character conversion support for "advancegreek"; based on patch from
213 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
214 sequence is met. Before the error was not set so it would be unknown.
216 Adjust yaz-marcdump MARC reader so that it skips until record separator
219 --- 2.1.52 2007/03/07
221 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
222 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
223 fd_set structure used as a bitmask for the FDs to be selected on.
225 Using ACX_PTHREAD macro to check for POSIX threads.
227 Fixed have-vsnprintf check.
229 --- 2.1.50 2007/02/23
231 Fixes for configure on BSD. Bug #900.
233 Added snprintf/vsnprintf wrappers for systems that don't have
234 limits (heavens forbid).
236 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
237 created before all previous tasks were completed and removed from the
238 task queue, the new task could be removed by a mistake.
240 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
242 Implemented pass-through CQL-to-PQF conversions. Bug #861.
244 Fixed bug #832: Problem with MARC/charset in yaz-client.
246 Fixed bug #668: save command line history for yaz-client.
248 Fixed bug #830: pkg-config support.
250 --- 2.1.48 2007/01/23
252 Extended ZOOM result set options with two options that may be read by
253 a client: resultSetStatus and presentStatus with values as specified for
255 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
257 Fixed bug #827: Using SSL fails on Debian etch.
259 Fixed bug #826: Weird looking chars for set of MARC records.
261 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
262 that is treated as an ItemOrder with itemRequest being an XML document
263 external. The value of "doc" is the content.
265 Extended the GFS search facility. New member of bend_search_rr
266 'estimated_hit_count' signals that hits is known to be an estmate
267 (higher or lower than real hit count). New member 'partial_resultset'
268 signals that the search was partial (hit count is lower or equal than
269 real hit count). For Z39.50, the information is stored in resultSetStatus
270 member of SearchResponse APDU. For SRU, the information is signalled
271 via SRU diagnostic 59: "Result set created with valid partial results
274 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
276 --- 2.1.46 2007/01/13
278 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
280 Added ZOOM_connection_peek_event.
282 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
283 the following new functions:
284 ZOOM_event_nonblock, ZOOM_connection_process,
285 ZOOM_connection_get_{socket,mask,timeout},
286 ZOOM_connection_fire_event_{timeout,socket}.
287 The existing blocking event handler, ZOOM_event, is a wrapper for the
288 + blocking ZOOM_event_sys_{poll,select}.
290 Implemented function ccl_xml_config which parses XML version of CCL
291 configuration (bug #798).
293 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
295 Added timings utility (yaz/timing.h)
297 --- 2.1.44 2007/01/03
299 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
302 Fixed bug #779: Rotation of apdu.log fails.
304 Fixed for character set conversions:
305 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
306 Honor G1 set in MARC-8 decoding.
308 --- 2.1.42 2006/12/17
310 Fixed bug #775: char conversion does not handle Alternative UTF-8
313 Implemented function yaz_marc_read_line which parses MARC line format
314 records. There is a wealth of formats out there. So far, this function
315 reads line records produced by yaz_marc_write_line.
317 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
318 more generic and easier to remember(!) options: -i format and -o format
319 which specifies input format and output format respectively - where
320 format is one of "marc", "marcxml", "line", "marcxchange".
322 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
323 does not print anything except warnings for records.
325 For yaz-marcdump, added support for MARC split into files (-s) with a given
328 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
329 spec, at http://www.loc.gov/standards/sru/record-update/
330 This has changed the binary layout of the following structs:
331 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
332 bend_update_rr . Patch by Ko van der Sloot.
334 Added GFS utility function bend_assoc_is_alive which returns 1 if
335 association is still alive (client is connected); 0 otherwise (client
336 closed connection). This allows busy servers to stop working for
339 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
340 been a separate piece of software. This version of ziffy has been modified
341 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
343 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
345 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
346 Client code may now interrogate options such as "init_opt_sort" to
347 find out whether the server claims to support various options.
349 --- 2.1.40 2006/11/27
351 Added utilities yaz_{set,get}_esn to set/get element set name from
354 Removed the build of libyazthread.la. The libyaz.so is the threaded version
355 of YAZ and has been so since YAZ 2.1.10.
357 Implemented ZOOM_record_error which returns error information for
358 record (surrogate diagnostic).
360 --- 2.1.38 2006/10/31
362 Updates for SRU Update by Ko van der Sloot:
363 1. Changed name from "operation" to "action"
364 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
365 versions in the code, marked as 'backward compatible'.
366 3. Added diagnostics for SRU Update.
368 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
370 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
372 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
374 For GFS, fixed problem with SRU diagnostic 'First record position out of
375 range' being issued for 0 hits.
377 zoomtst10 part of Windows Build.
379 --- 2.1.36 2006/10/13
381 Implemented yaz_filepath_comp which splits a path into file path
382 components (required by Zebra 2.0.3+).
384 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
385 BSD inspired license until now so this should not have any real impact on
386 anybody. See http://www.opensource.org/licenses/bsd-license.php
388 Fixed bug #687: Missing log lines.
390 Fixed bug #678: CQL to PQF translation does not preserve double-quote
393 Fixed bug #689: SRU diagnostics to be added.
395 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
396 whether a connection is idle (no more work do do).
398 --- 2.1.34 2006/10/04
400 Change type of optval from long to int for invocation of setsockopt with
401 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
403 Added support for specifying the max log file size for the Generic
404 Frontend Server. The size is given with option -r.
406 --- 2.1.32 2006/09/21
408 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
410 --- 2.1.30 2006/09/17
412 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
415 Fixed bug in Generic Frontend Server that could cause a server to stop
416 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
418 For the generic frontend server, the maximum record size is used as maximum
419 size of incoming packages (SRU + Z39.50). The value until was previously
420 only used in Z39.50 Init negotiation and, later, in a session controlled
421 sizes of records returned. This is controlled using -k option. It can be
422 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
424 --- 2.1.28 2006/09/04
426 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
429 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
431 New option for yaz-marcdump -lpos=value which allows setting a portion
432 of MARC header to a certain value.
434 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
436 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
437 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
439 --- 2.1.26 2006/08/15
441 Fixed problem with SRU mode type (soap, get, post) for yaz-client
444 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
446 --- 2.1.24 2006/08/08
448 Fixed MARC ISO2709 encoding routines to deal with character set
451 Minor changes to GFS logging. Database included in search request log
454 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
455 cached/multiple records.
457 Shared libraries are built by default on Unix+configure.
459 Changed cql2pqf transformation to use a different evaluation order. The
460 new order is: always, relation, structure, position, truncation, index
461 and relationModifier. Old order was: always, relation, relationModifier,
462 structure, index, position, truncation. Note that the the latter ones
463 override former ones for identical attributes.. The new scheme means that
464 it is possible to override any existing attribute with a relationModifier.
465 And also that it is possible to override everything for the index rule
466 (except the ones listed in relationModifier). No order is perfect but this
467 one, we believe, covers more real cases.. The "always" should have been
468 called "default", since the attributes there can be overridden with all
471 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
472 compilation phase, but also for yaz-config --cflags output. This allows
473 us to have public headers with Libxml2 stuff in them . It should also,
474 eventually, make Libxml2 checks redundant in packages using YAZ, such
477 --- 2.1.22 2006/06/15
479 Changed SRU update structure bend_update_rr so that SRU diagnostics are
480 stored in uri, message and details.. Previously diagnostics were stored
481 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
482 compatibility.. but he's probably the only one affected, so.
484 Added support for CCL, compiled on the client side, in ZOOM-C. This
485 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
486 input; the resulting query objects can be used for for searching with
487 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
489 YAZ' configure searches for OpenSSL by default.
491 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
492 SL_CTX_use_certificate_file. See
493 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
494 for more info. Thanks to Ko van der Sloot.
496 --- 2.1.20 2006/06/02
498 Bug #600: SRU GET, POST support for yaz-client. Introduced
499 command 'sru' which selects method SOAP/GET/POST.
501 Allow missingValueAction to be specified for the sortspec string -
502 function yaz_sort_spec. By default, the missing value action is null.
503 Use ! to specify "abort". Use = followed by stringvalue to specify default
506 Ensured that Present-handler (if defined) is called in GFS before any call to
507 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
508 searchRetrieve requests.
510 Documentation for YAZ is now based on the Docbook XML/XSLT using
511 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
512 is no longer depending on jade/openjade or docbook-to-man scripts.
513 PDF is no longer part of the distribution - but can optionally be
514 made using DSSSL/jadetex or FOP.
516 Added retrieval handling support in Generic Frontend Server to support
517 conversion between MARC/XML as well as XSLTtransforms. See
518 etc/yazgfs.xml for an example.
520 Added Authentication support to Generic Frontend Server in SRU
521 mode. Authentication using HTTP Basic is supported, as is the use
522 of 'x-username' and 'x-password' parameters in the request itself.
524 Added support for a new character set MARC8s identical to MARC8 except
525 that it converts combined characters to single Unicode characters in the
526 Latin-1 range (when possible).
528 --- 2.1.18 2006/04/24
530 ASN.1 compiler 0.4: generates brief Doxygen file header for
531 generated .h/.c files.
533 Utility yaz_iconv now supports conversion to MARC-8.
535 New facilities for the MARC module. The reading - and writing of
536 content are separate methods for the yaz_marc_t handle. The following
537 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
538 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
539 format). Write functions have prefix yaz_marc_write_.. The existing
540 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
541 available. Removed support for OAI-MARC and simplexml (not the
542 simplexml from PHP5).
544 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
545 to be returned for this connection.
547 --- 2.1.16 2006/03/31
549 Allow multiple languages and charsets to be specified with
550 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
551 negcharset iso-8859-1,utf-8
553 Translation of proximity nodes from CQL into PQF now works.
555 Moved to automake 1.8, 1.9.
557 Added function yaz_log_set_handler which allows a log handler to be
558 installed. This handler will be called for all log messages. Output
559 to file is also produced; but that can be disabled by passing NULL
560 fname to yaz_log_init_file.
562 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
564 For SRW (including GFS), accept application/soap+xml as content-type
567 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
568 produces NO stylesheet reference even if a default stylesheet is specified
571 --- 2.1.14 2006/03/14
573 Updated Windows package to include yazd.dll + yazd.lib for the
574 Development component.
576 If the environment variable YAZ_LOG is set, then it is used as a
577 string indicating the default level of logging to use if not
578 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
579 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
580 used as before. So, for example, to omit warnings from YAZ logging,
583 cql_transform() now map structure and other attributes before indexes,
584 so that index-specific structures and other attributes can override
585 defaults. So now a combination of mapping specifications such as:
587 index.dc.date = 1=date-modified 4=5
588 does the right thing.
590 cql_transform() now also respects the "always" mapping specification,
591 which establishes an initial set of attributes to be used for all
592 terms except where overridden by more specific attributes associated
593 with the index, relation or modifier.
595 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
596 which mode to use; one of "post", "get" or "soap" (SRW, default).
598 Fixes for yaz_iconv routines: changed trie-based character set conversions
599 to use only non-negative values for bit fields due to Sun's C compiler not
600 supporting negative values.
602 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
603 sequences where not read correctly. Fix by Rustam Usmanov.
605 Updated win/makefile to use options, settings which makes things
606 compile with VS C 2005.
608 --- 2.1.12 2006/02/01
610 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
612 In ZOOM socket code, use select instead of poll on MacOSX.
614 ZOOM-C now support client-side compilation of CQL into RPN that is
615 sent to the server, enabling CQL to be used against all Z39.50
616 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
617 ZOOM_query object, and submit it using ZOOM_connection_search().
618 The CQL-to-RPN translation uses a configuration file, the name of
619 which must be specified in the Connection's "cqlfile" option.
621 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
622 function, which takes as its start-term parameter a ZOOM_query object
623 (which may have had either CQL or RPN set into it).
626 --- 2.1.10 2005/11/29
628 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
629 GFS to support this as well. Backend handler, bend_srw_update, does the
630 update work. Code contributed by Ko van der Sloot.
632 Allow retrieval of Search Result-1 information in ZOOM by the use of
633 options that are attached to a result set. ZOOM documentation updated
636 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
637 UTF-8 conversion. Patch by Raj Patel.
639 Added option -m to GFS to control formatting of timestamps in log file.
641 Added 'exit' as synonym for 'quit' in yaz-client
643 Added support for specifying SRW resultSetId + resultSetIdleTime in a
644 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
645 for the new members. Patch by Ko van der Sloot.
647 Added support for SRU POST. It is supported for content-type
648 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
650 Do not build the separate Multi-threaded (MT) library libyazthread.la.
651 Instead make the library libyaz.la multi-threaded. Threading as a whole
652 can still be disabled by configure option --disable-threads. Previosly,
653 with older GLIBCs there were problems with MT libs under Apache. This
654 has now been fixed a long time ago.
656 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
659 CQL module modified to be case insensitive for relations/indexes/operations.
661 Fixed bug in CQL transform code: incorrect value relationModifieder
664 Added 'show all' command for yaz-client which retrieves all results
667 Added new yaz-client, xmles, which takes a (private) OID and
668 a document to be sent as an extended service request.
670 Describe new yaz-client commands wait_response and set_auto_wait.
672 Increase TCP/IP listener backlog from 3 (which I am guessing was
673 copied from the SunOS manual entry way back when) so SOMAXCONN, so
674 that the socket will queue as many incoming connections as it's able
675 to handle ongoing connections. In other words, it will never now
676 refuse a connection that it would be able to handle merely because
677 it's not got around to accepting() enough of the pending connections
678 yet. This is the behaviour anyway under Linux, where the listen()
679 argument is ignored; but not under BSD and on systems such as
680 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
681 YAZ-based servers should now be uniform across operating systems in
684 yaz-marcdump uses 64-bit file access on some systems. This is enabled
685 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
686 This allows yaz-marcdump to read large MARC batches (>2 GB).
688 Modified all YAZ source files - except the source which is auto-generated
689 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
692 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
693 corresponding to the existing *_setl() function. These allow option
694 values containing arbitrary valuues.
696 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
697 ZOOM_resultset_sort() in new applications. Its behaviour is identical
698 except that it returns an indicator of whether or not the sort
699 criterion was accepted (0 for OK, -1 for invalid).
703 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
704 MARC output rather than returning "new" buffer.
706 yaz-client warns about unknown init options.
708 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
712 Added support for SRW sort in Generic Frontend Server. Patch
713 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
714 sortKeys - or NULL if none is provided.
716 Fixed bug #307: It was impossible to specify indefinite/no timeout
717 for ZOOM_event. Special timeout value -1 now means indefinite timeout
720 Added support for multiple languages and charsets to be specified in
721 ZOOM. Each charset/language is separated by a blank. If negotiation is
722 in effect in init-response, Option
723 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
724 Code based on patch by Vasiliy Osadchuk.
726 Fixed bug #306: infinite recursion that occurred when calling
727 yaz_log_level_init as the first call (before other log level or
730 Fixed bug in scan handling in front end server: if preferred-Position-In-
731 Response was non-present, a NULL pointer referece was performed.
735 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
736 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
737 now defined for all those error codes. So instead of putting 109 in
738 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
739 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
741 Modified the yaz-marcdump utility to skip garbage bytes between MARC
744 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
746 Program yaz-client now exits and produces an error message if multiple
747 Z39.50 servers are specified on the command line (none or one allowed
750 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
755 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
757 Fixed bug #272: Preserve spacing for CCL terms.
761 Added support for virtual hosts and multiple backend servers for
762 the YAZ frontend server. The configution is XML based and
763 support specificition of CQL to RPN mappings and explain information.
764 See section "Virtual Hosts" in the YAZ manual.
766 Extended OPAC display utility. OPAC display utility renders
767 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
768 to supplement yaz_marc_decode_wrbuf.
770 Fixed a bug in MARC decoder that could caused it to crash for some
771 invalid MARC records. More diagnostics and warnings where added in
772 XML output (warnings, etc are stored in comments).
774 --- 2.0.34 2005/02/08
776 Fixes for UNIX domain sockets. Bug #261.
778 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
780 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
781 Added yaz_marc_subfield_str which defines subfield lead string which is
782 used in YAZ_MARC_LINE format. Default string is blank+$. Added
783 yaz_marc_endline_str which defines end of fields string used in
784 YAZ_MARC_LINE format. Default string is newline.
786 Experimental support for MarcXChange. This format can be produced
787 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
788 http://www.bs.dk/standards/MarcXchange.xsd
790 Added yaz-client commands scansize that sets maximum number of
791 entries to be returned by scan.
793 --- 2.0.32 2005/01/11
795 Added support for SRW scan in yaz-client and Generic Frontend Server.
797 * Added whereInList member to SRW Scan Term.
799 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
801 Fixed NMEM system to return aligned blocks on the smallest boundaries
802 that are suitably aligned for all possible types on the particular
803 architecture YAZ is being built for.
805 --- 2.0.30 2005/01/04
807 Fixed numerious warnings that was issued with newer versions of GCC.
809 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
810 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
813 Make YAZ Generic Frontend Server slightly faster.
815 Enhance (and reduce) logging for Generic Frontend Server.
817 Revert YAZ log system so that it flushes every write operation
818 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
820 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
821 instead of LOG_, due to name clash with syslog(3). LOG_ are still
822 present. New applications should define YAZ_USE_NEW_LOG=1 - this
823 will effectively disable old definitions.
825 --- 2.0.28 2004/11/09
827 Added yaz_log_time_format which specifies log format using
830 Added yaz_log_module_level which returns mask for a module. Value
831 is non-zero mask a if module is enabled; zero if disabled.
833 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
834 in include/yaz/cql.h.
836 Fixed bug #176: Dont throw diagnostics on empty SRU args.
838 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
840 Fixed bug #172: RPM builds does not enable SSL.
842 Doxyfile.in part of dist. Doxyfile generated by configure.
844 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
845 are given and the corresponding component does not exist.
847 Extend CCL documentation in YAZ reference. Describe r=r.
849 --- 2.0.26 2004/10/01
851 Fixed MARC->MARCXML conversion to properly deal with
852 fields, subfields, indicators having non-ASCII characters.
854 Fixed MARC->MARCXML conversion so that ASCII control characters
855 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
858 Added YAZ GFS support for conversion from Z39.50 surrogate
859 diagnostics to SRW surrogate diagnostics.
861 Bug fix: YAZ GFS did not return schema in explainResponse.
863 --- 2.0.25 2004/09/30
865 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
866 now converts recordSchema to elementSetName as well as schema URI.
868 Fixed bug in COMSTACK that prevented HTTP request packages from being
871 --- 2.0.24 2004/09/29
873 Added CCL facility r=r "range" which is similar to r=o "ordered" but
874 does not require white-space before and after the dash in a range, e.g.
875 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
878 Fixed a few AC_TRY_LINK configure tests that did not operate properly
879 due to new GCC removing "redundant" code.
881 Added yaz-client commands scanpos and scanstep that sets preferred
882 position and step-size for scan.
884 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
886 Added CCL utility ccl_qual_buf which parses one or more CCL
887 spec lines in a buffer.
889 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
890 of name and value - ignoring empty lines and comments.
892 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
894 Added odr_get_element_path which returns current element path for an
895 ODR handle. This utility is useful in error handling or user-defined
898 Added ODR_PRINT utility odr_set_stream which is is a more generic
899 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
900 to a write function and pointer to close function. The close function - if
901 non-NULL - will be called during odr_destroy.
903 Fixed bug in CCL parser where truncation char was not removed from
904 right side when truncation=both was in effect.
906 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
909 --- 2.0.23 2004/08/11
911 Fix buffer overrun in CQL parser when dealing with proximity (%).
913 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
914 to UTF-8/UCS conversion is now only based on codetables.xml.
916 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
918 --- 2.0.22 2004/08/06
920 Add support for more "commit changes" in ZOOM (uses Extended Services).
922 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
925 Yet another small fix for configure of SSL.
927 --- 2.0.21 2004/05/14
929 Fix SSL libs for configure when --with-openssl=DIR is given.
931 --- 2.0.20 2004/05/10
933 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
935 SSL comstack now uses yaz.pem certificate file on server side
936 by default. Certificate filename can be configured by calling
937 comstack function cs_set_ssl_certificate_file before cs_bind is used.
939 Fix bug regarding multiple calls to ZOOM_connection_connect.
941 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
943 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
944 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
946 ZOOM now allows inspection of X509 peer certificate for verification.
947 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
949 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
950 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
951 as "modular" but it simplifies things.
953 Added cs_get_peer_certificate to that returns peer X509 PEM.
955 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
956 NULL if SSL is unavailable.
958 Documentation about MARC decoding tools.
960 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
962 --- 2.0.19 2004/03/30
964 Rename CHANGELOG to NEWS to follow GNU style packing.
966 Fix bug with missing initialization of member in init_diagnostics.
967 This bug affects threaded version of GFS server.
969 --- 2.0.18 2004/03/20
971 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
974 Ensure zlib.dll is packed with Windows install.
976 --- 2.0.17 2004/03/17
978 Fix encoding of xsd:string to use text instead of CDATA.
980 Fix endless loop in CQL parser with unbalanced ".
982 Use a more compact way to store MARC-8 conversion tables.
984 --- 2.0.16 2004/03/16 Debian only
986 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
989 Update CQL parser to use new CQL 1.1 modifiers for booleans and
994 --- 2.0.15 2004/03/01
996 Another fix for decoding of XML packed records.
998 --- 2.0.14 2004/02/25
1000 Fixes for Chunked encoding. White space not ignored after length spec.
1002 Update NS and use default NS for SRW diagnostic elements.
1004 --- 2.0.13 2004/02/23
1006 Implement ZOOM_resultset_cache_reset which resets record cache.
1008 Implement ZOOM_resultset_sort which sorts a result set.
1010 Implement chunked HTTP transfer.
1012 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1014 --- 2.0.12 2004/02/16
1016 Added member 'schema' to bend_explain_rr structure so that backend
1017 can specify explain record identifier. Defaults to Zeerex 2.0.
1019 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1021 --- 2.0.11 2004/02/16
1023 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1026 Added init command for yaz-client which sends "extra" init request.
1028 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1029 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1031 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1033 Make ZOOM error code for "invalid query".
1035 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1037 --- 2.0.10 2004/02/05
1039 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1042 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1044 Added option -p <file> to make Generic Frontend Server to write PID file.
1046 Added option -D to put Generic Frontend Server in background on its own.
1048 Make ZOOM C recognize option "password". If unset, "pass" is used
1049 (for backwards compatibility).
1051 Fixed a bug in Generic Frontend Server that could make it crash if a
1052 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1055 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1056 Must be issued before open, in order to be in effect.
1058 --- 2.0.9-6 2004/01/12 Debian/Windows
1060 Make the SRU server more picky WRT unknown params, etc.
1062 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1064 New YAZ client command, options, that sets Z39.50 options.
1066 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1067 options from a string of tokens (one token for each option bit).
1069 Update SRW diagnostic code messages.
1071 --- 2.0.9-5 2004/01/07 Debian/Windows
1073 Handle user defined stylesheet for SRW/SRU.
1075 --- 2.0.9-4 2004/01/06 Debian/Windows
1077 Fix bug in decoding of Content-Length.
1079 --- 2.0.9-3 2004/01/06 Debian/Windows
1081 Fix a bug with decoding of XML packed records.
1083 --- 2.0.9-2 2004/01/05 Debian only
1085 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1087 Fix bug in SRW/SRU diagnostics decoding.
1089 --- 2.0.9 2004/01/05
1091 Fixed bug in Generic Frontend Server which could drop records exceeding
1092 preferred message size. Reported and fixed by Irina Dijour.
1094 Fixed calculation of package size for structured records in Generic
1095 Frontend Server. Reported and fixed by Irina Dijour.
1097 Fixed namespace for SRW/SRU diagnostics.
1099 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1101 --- 2.0.8 2003/12/22
1103 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1104 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1107 CQL changes to reflect recent changes to the specification:
1108 * Documentation talks about context sets instead of index sets.
1109 * Documentation talks about indexes instead of qualifiers.
1110 * The CQL-to-PQF transformer's configuration file now uses
1111 "index.set.name = <attributes>" instead of the old form
1112 "qualifier.set.name = <attributes>". (Both forms are still
1113 understood but the latter is deprecated.)
1114 * CQL terms with no explicit index specified are now interpreted as
1115 cql.serverChoice instead of srw.serverChoice (which of course
1116 behaves exactly the same.)
1118 --- 2.0.7 2003/12/16
1120 MARC conversion can now generate ISO2709 output in another
1121 character set. yaz-marcdump uses this facility if you invoke it
1124 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1125 functions from there can be used from C++.
1127 --- 2.0.6 2003/12/04
1129 Frontend server now transfers memory from decoded packages to stream
1132 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1133 references to show up.
1135 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1136 the ZOOM Abstract API. The older names for the same options are still
1137 also supported for the benefit of old applications.
1139 ZOOM-C supports "implementationId" and "implementationVersion" options
1140 to go along with "implementationName". These allow the user code to
1141 specify identification strings to be sent to servers.
1142 Add OID for the new ExtLite attribute set.
1144 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1145 as requested/supplid by Ere Maijala <ere@atp.fi>
1147 For generic frontend server, reverse the order of
1148 "toolkit-supplied / application-supplied" strings sent as implementationId,
1149 Name and Version. Also, remove the spaces around the slash. This brings
1150 the GFS in line with the behaviour of ZOOM-C on the client side.
1152 Add function ZOOM_scanset_display_term.
1154 yaz-client shows scan displayTerm if present.
1156 Utility yaz-iconv is now installed by default along with the man page
1159 Extend configure check for OpenSSL to use pkg-config where available (such
1162 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1163 server to specify uid/gid/mask for socket using the format
1164 unix:[user=uid,][group=gid,][umask=mask,]file=path
1165 If file= is omitted the existing format is assumed, e.g.
1167 in which case the mask is 0666 (rw for everybody).
1169 Major restructure of YAZ source. All source in libyaz is in src directory.
1170 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1171 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1173 Added man page for utility yaz-marcdump (used to be called marcdump).
1174 yaz-marcdump is installed by 'make install'.
1176 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1177 of incoming package failed.
1179 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1181 Change prototype of odr_perror: add const to message string.
1183 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1185 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1186 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1187 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1188 DNS lookup. There should not be any compatibility problems with this
1189 assuming that blocking=1 or 0 is used.
1191 Fix bad reference in UNIX comstack in function cs_addrstr.
1193 Fix for compilation on AIX.
1195 The generic front-end server (server/seshigh.c) now supports returning
1196 Init diagnostics to the client in User-information-field, in
1197 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1200 --- 2.0.4 2003/09/04
1202 Allow any CQL relation (not just all,any,exact,scr).
1204 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1205 that features the same UI.
1207 Implemented command update0 in YAZ client which is equivalent to
1208 update but uses old of Ext Update ASN.1.
1210 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1211 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1212 Previously no OID was used for this info.
1214 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1215 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1216 returns 'malformed search term' otherwise.
1218 SortResponse member resultCount now set to NULL in sort handler of
1221 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1224 Add three new utility functions for translating OIDs between various
1225 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1226 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1227 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1228 char *oid_to_dotstring(const int *oid, char *oidbuf);
1229 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1231 Reverted modifications for ES Update definition for z_IU0Update
1232 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1233 is back to YAZ 2.0.2.
1235 String value attributes for CCL parser.
1237 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1238 which their FirstSearch server returns in Init responses, sometimes
1239 carrying useful diagnostic information when Init fails. This has the
1240 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1241 "z39.50/oclcui.asn", where its definition is somewhat different from
1242 what OCLC document on their web-site, as required to interoperate with
1245 Support for anonymous authentication in yaz-client. Use the command
1248 * Fix the OID of the Index Data-local "admin" Extended Service from
1249 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1250 the 1000, which indicates a locally-defined OID, was a mistake.
1252 --- 2.0.3 2003/06/20
1254 Fix CCL directive @case handling so that it affects string match for
1255 both CCL keywords and qualifiers.
1257 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1258 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1259 Decoder has been updated with ASN.1 changes as listed in
1260 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1261 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1262 z_IUUpdate, remains unchanged.
1264 ZOOM_record_get may now return a record in a specific character set.
1265 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1266 "from" is the character set of record as returned by target. "to" is
1267 the character set to be returned. If omitted, "to" is UTF-8.
1269 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1271 New ODR utility, odr_getelement, which returns name of element for
1272 which encoding/decoding failed.
1274 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1275 in cases where a required element was omitted.
1277 Bug fix: some MARC8 sequences were not converted.
1279 New ZOOM option "step" which specifies number of records to be
1280 retrieved in one chunk. Used in conjunction with "start" and "count".
1282 SRW support for yaz-client. Use scheme http: to use it, e.g.
1285 yaz-client no longer does (un)intelligent character set conversions
1286 by default. Can be enabled with charset and marc_charset commands.
1288 xmalloc trace fix for 64-bit systems such as DEC alpha.
1290 Solaris 2.6 compile fix.
1292 New function, cql_strerror() translates SRW error codes, as returned
1293 by cql_transform_error(), into human-readable English strings. Used
1294 in yaz-client diagnostics when appropriate.
1296 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1297 converts it into a type-1 query which is sent to the server. This
1298 makes CQL available for use with all Z-servers, as opposed to the tiny
1299 minority that can handle CQL queries themselves.
1301 --- 2.0.2 2003/04/28
1303 New Debian package layout similar to the Redhat Package layout.
1305 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1306 and search result respectively.
1308 --- 2.0.1 2003/04/25
1310 Redhat package is now several packages: libyaz (runtime libraries),
1311 libyaz-devel (development and documentation, and yaz (utility programs).
1312 Package spec file by Morten Bøgeskov.
1314 New member 'schema' in struct bend_fetch_rr which the name of requested
1315 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1316 handler MAY set this to reflect the schema of the returned record.
1318 New member 'display_term' in struct scan_entry. GFS now sets member entries
1319 and allocates scan entries to be filled by user scan handler. In previous
1320 version, entries member was allocated by the scan handler. That still works,
1321 but the GFS will ignore member display_term - assuming it was NOT set by
1322 the handler. The fact that the GFS now allocates the entries both allows
1323 for new members and makes a scan handler easier to write.
1325 Fix CQL lex buffer overflow.
1327 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1328 SRU default recordPacking is string.
1330 SRU protocol support for frontend server.
1332 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1334 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1336 Added scan for the ZOOM shell (zoomsh).
1340 * String Identifers for Schemas (Amendment 5).
1341 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1342 Old definition for schema
1343 Odr_oid *schema; /* OPT */
1348 Z_InternationalString *uri;
1349 #define Z_Schema_oid 1
1350 #define Z_Schema_uri 2
1353 * resultCount parameter to Sort Response (Amendment 1).
1354 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1356 Support for SRW 1.0 over HTTP. This is an optional feature and
1357 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1360 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1361 on the same port. SRW SearchRetrieveRequests are mapped
1362 to bend_init,bend_search,bend_fetch,bend_close.
1364 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1366 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1367 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1369 ZOOM connections are SRW based if schem http is used for hostname
1370 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1371 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1373 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1374 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1375 distance=n, order=true/false, relation=le, prox unit=word. If
1376 n is omitted, distance 1 is used.
1378 Fixed problem with C compiler include path in wrong order.
1380 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1381 on Solaris. Patch from Ko van der Sloot.
1383 New MARC decode API. All new functions operate on a yaz_marc_t
1384 handle. The most important new functions are: yaz_marc_create,
1385 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1386 decode and destroy respectively. Decoder can produce formats
1387 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1388 include/yaz/marcdisp.h.
1390 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1391 to UTF-8, UCS-32, wchar_t or Latin-1.
1393 * Prototypes for yaz_iconv_-functions moved to separate header
1394 include/yaz/yaz-iconv.h.
1396 Make a few private functions 'static' in unix.c. This prevents
1397 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1399 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1400 are set when Init Response is received.
1402 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1403 but returns diagnostic set as well.
1405 New function yaz_strerror which is a portable wrapper for
1406 strerror/strerror_r/GetLastMessage.
1408 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1409 is returned for MARC. If type is "oai", then OAI MARC is returned.
1411 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1414 --- 1.9.2 2002/11/26
1416 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1418 Fix bad race conditions on SIGTERM and terminate gracefully in
1421 Move retrieval (data1) module to Zebra since nobody seems to be
1424 Add GRS-1 render for ZOOM using same format as yaz-client.
1426 --- 1.9.1 2002/10/05
1428 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1430 Fix broken ESpec handling in data1 module.
1432 SGML reader parses comments and makes them part of the data1 tree.
1434 Added several type casts so that YAZ compiles as C++ code.
1436 ZOOM didn't handle PDU encoding failures properly.
1438 Added more Bib-1 diagnostics (approved extensions).
1440 GNU configure: better check for iconv.
1442 More portable use of accept, getpeername. Check for socklen_t. Use
1443 int/size_t if socklen_t is not defined.
1447 PQF parser rejects bad queries - including those with extra
1448 characters in them. PQF parser used to silently ignore that.
1449 Cleaner API for PQF added, which allows you to get detailed
1450 error information for bad queries (see yaz/pquery.h).
1452 Fixed bug in ZOOM_record_get for type "database".
1454 Implemented mini iconv library supporting conversions between
1455 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1457 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1459 --- 1.8.9 2002/08/20
1461 Fixed ZOOM C record cache so that preferredRecordSyntax and
1462 elementSetName is used to check for already fetched records.
1464 --- 1.8.8 2002/08/02
1466 Added three members in bend_initrequest structure to facilitate
1467 character set negotiation.
1469 Fixed a bug in frontend server that could cause indefinite
1470 loops under rare conditions.
1472 Revised character set utilities (charneg.h) so that encoding
1473 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1475 For PQF, directive @term <type> sets term type for Scan/Search.
1476 Here <type> is general, string, numeric, null. The term type
1477 is inherited - just like @attr.
1479 New call odr_set_charset that sets character set conversion for
1480 international-strings on a ODR stream. Prototype is:
1481 int odr_set_charset(ODR o, const char *to, const char *from);
1482 The InternationalString is still represented as C string in YAZ
1483 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1484 won't). On the protocol level, you can use any encoding.
1486 Support for UNIX sockets in ZOOM.
1488 Solaris recv sometimes returns errno == ENOENT. It is treated as
1489 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1491 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1492 both client and server. Code by Morten Bøgeskov.
1494 --- 1.8.7 2002/05/22
1496 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1497 that they can be used directly from Visual Basic. You must recompile
1498 your windows APP if you're using ZOOM.
1500 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1501 Commands "lang" and "charset" sets language and character set respectively.
1502 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1503 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1505 Attributes from multiple CCL fields may be OR'ed rather than merged
1506 using directive "@field or". Fields are still merged by default -
1507 equivalent to "@field merge".
1509 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1512 Fixed bug in zget for parameter ExtendedServicesResponse.
1516 --- 1.8.6 2002/03/25
1518 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1520 Client displays USR.1:SearchResult-1 (hits per term).
1522 Additional Search Info for search in Generic Frontend Server.
1524 Fixed CCL parsing of "field=s".
1526 WIN32 installer - using the excellent NSIS software from nullsoft.
1528 Fixed CCL parsing of "field = - <number>".
1530 Added function yaz_marc_decode that decodes MARC for line mode
1531 display or XML (similar to that used by JZKit).
1533 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1534 Z39.50. But ISO/ILL was, however.
1536 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1537 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1539 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1540 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1542 --- 1.8.5 2002/02/03
1544 New YAZ client features: Command completion and new commands:
1545 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1546 Code provided by Jacob Poulsen.
1548 New call oid_trav, that visits all registered OIDs via callback.
1550 Function ZOOM_record_get now returns const char pointer rather than
1551 void pointer. It saves a lot of type casts.
1553 For YAZ client, command "auth" now allows you to set authentication
1554 in IdPass style. It is enabled when three tokens are given - order
1555 is user, group and password.
1557 Fix memory leaks in MARC record handling for ZOOM.
1559 New option for YAZ client, -k <kilobytes> that sets
1560 maximum record size. Similar to -k option for generic frontend
1561 server and yaz-ztest.
1563 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1565 Prefix query parser reports "fail" when bad attribute set is given.
1567 Fix in MARC decoder. Proximity logging. Fix for attribute set
1568 in scan handler for server. Patches by Shigeru Ishida.
1570 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1573 Configure option --with-openssl=<dir> now works when a directory is
1574 specified. Patch provided by Morten Bøgeskov.
1576 New option for YAZ client, -u <auth>, that sets authentication.
1578 ZOOM fix: error information was sometimes "missing", since error
1579 was cleared/reset too when it shouldn't.
1581 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1583 --- 1.8.4 2002/01/04
1585 Scan for ZOOM API. New object ZOOM_scanset. New functions
1586 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1587 ZOOM_scanset_destroy.
1589 New ZOOM function, ZOOM_connection_last_event, that returns type
1590 of last event (such as "receive data", "send data", "apdu received",
1593 New ZOOM option, schema, that specifies schema for retrieval.
1595 New CCL feature. Qualifiers can be aliases for one or more
1596 other qualifiers (if more than one is given, OR is used).
1598 ZOOM uses named result sets if target supports it.
1600 Two new YAZ client commands: . (dot, which sources a script of YAZ
1601 client commands), and ! (to execute shell command.). Implemented
1604 Working on Debian packages.
1606 --- 1.8.3 2001/11/19
1608 YAZ client enables named result sets only if target supports it.
1610 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1612 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1613 with key="host" to get same result.
1615 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1616 Function Z3950_resultset_record(s) returns references to records
1617 "owned" by resultset. To become owner use Z3950_record_clone.
1619 Function z_ext_record handles Extended Services. Thanks to
1622 --- 1.8.2 2001/11/12
1624 CCL Parser fix: ignore token comma when dealing with and-lists.
1626 Documentation updates for COMSTACK.
1628 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1629 Changed prototype Z3950_records. For some functions, int parameters
1630 were changed to size_t.
1632 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1635 New MARC decode/display function, marc_display_exl, which properly rejects
1636 non-ISO2709 records. YAZ client uses it.
1638 --- 1.8.1 2001/10/29
1640 Fix bug: local attribute set wasn't set correctly in PQF strings.
1644 * Old Z39.50 codecs no longer supported.
1646 Added ZOOM C binding. See http://zoom.z3950.org/
1648 Renamed states for COMSTACKs to avoid confusion with events.
1650 Implemented cs_look and proper cs_rcvconnect.
1652 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1654 Configure detects POSIX threads on OpenBSD.
1656 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1657 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1659 When error is returned from present handler, non-surrogate diagnostic
1660 is returned in present response (and fetch handler is no longer called).
1662 * Minor adjustments to pquery parser (PQF). Token characters may be
1663 escaped by using backslash (C-style).
1665 PQF parser allows string attribute values to be specified. For @attr,
1666 non-numeric characters after the equal-sign are treated as strings
1667 (e.g. @attr 9=title).
1669 CCL trunction character may be defined (@truncation in file)
1671 * function zget_ExtendedServicesRequest sets waitAction to
1672 waitIfPossible (was wait).
1674 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1677 CCL operator names may be set in field definition files (CCL_bibset).
1678 See ccl/bib1 for an example.
1680 Fixes in ASN.1 compiler for C++ compatibility.
1682 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1683 and "op_or" to avoid conflict with C++.
1685 Fixed problem with GNU readline detection on Redhat 7.0.
1687 Added step-size for Scan backend handler.
1689 Fixed bug that made the frontend server crash when no attribute
1690 set was specified for scan.
1692 Front-end server automatically switches to original working directory
1693 when installed as an NT service. Previously -w had to be specified to
1696 Added extended attributes for retrieval module (data1), so that data1
1697 records carry d1_readXML/SGML attributes. d1_read also supports
1698 null-data rules ( <tag/>)
1700 On UNIX when POSIX threads are available, a separate library libyazthread
1701 is created. Programmers should link with that library and the yaz library
1702 when using threads. The reason for the split was that some applications
1703 on Linux, such as Apache, doesn't work well when using shared objects that
1706 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1707 (or any frontend server) in SSL mode by specifying ssl: followed by
1708 address. Only tested on UNIX.
1710 Added feature for CCL module. Virtual structure s=al or s=ol generates
1711 and-list and or-list respectively instead of phrase search.
1715 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1716 log_mask_str. This was done to avoid name conflicts with other libraries
1717 (such as other PHP extensions).
1719 Added raw OID member for preferred record syntax (request_format_raw)
1720 and returned record syntax (output_format_raw) for backend fetch method.
1722 Config file yaz-config now accepts options so that it returns specific
1723 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1725 Shared library support for UNIX using GNU libtool.
1727 * Modified backend interface. Request/Response struct's replaced by
1728 one read/write C struct. For example bend_fetchrequest and
1729 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1730 Every handler - even search has to be registered in bend_init
1731 handler. This means that the YAZ library no longer refers to
1732 external functions and it makes it possible to make the whole
1733 thing a single DLL/SO.
1735 Added Segment handler for backend server.
1737 Added Zmbol/Zebra administrative functions to YAZ client.
1739 Threaded frontend server on UNIX (when POSIX Threads are available).
1740 Starting the server with option -T enables multi-threading.
1744 Added configure option --enable-comp/disable-comp to control use
1745 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1746 located in sub directory asn.
1748 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1749 in ${exec_prefix}/bin along with the other programs yaz-client and
1752 GNU automake used to maintain makefiles.
1754 Added several OID's.
1756 Changed retrieval module so that we can load records with no abstract
1757 syntax defined. Tagpaths in these records are fully composed of string
1760 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1764 On UNIX, the generated makefile now supports a proper 'make install'.
1765 The prefix can be set via GNU configure to set the install location
1766 (default is /usr/local).
1768 * YAZ programs client and ztest were renamed to yaz-client and
1769 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1770 locations, such as /usr/bin,/usr/local/bin,etc.
1772 * YAZ Header files were moved from include to include/yaz. YAZ Header
1773 files are referred to as include <yaz/log.h> rather than <log.h>.
1774 The YAZ include path (-I ..) is therefore the same as before. Programmers
1775 should update their #include statements or use -Ipath/include/yaz
1776 instead. The main motivation for doing this change is that YAZ header files
1777 can be installed in "standard" locations /usr/include,/usr/local/include
1778 without introducing conflicts, since ALL YAZ header files are stored
1779 in subdirectory yaz (under /usr/include for example).
1781 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1782 rather than project/workspace files. We switched because project files
1783 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1786 Changed name of logging function, logf, to yaz_log, to prevent name
1787 clash with some math-log functions. The YAZ header log.h defines logf
1788 to yaz_log (#define) so there should be no incompatibilities by this
1791 Added bend_start/bend_stop handlers for server. These handler are
1792 called on start/stop of server. For windows they are called whenever
1793 a service is started/stopped.
1795 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1796 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1797 in util/yc.tcl. The auto-generated C code structures are, in a few
1798 cases, incompatible with the old decoders. There are differences in the
1799 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1800 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1801 The preprocessor variable ASN_COMPILED is defined when the compiled
1802 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1803 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1804 wish to use the old encoders/decoders you can specify --disable-yc
1807 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1808 version so that it supports both new - and old version of DB Update
1810 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1811 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1812 change. The name parameter can be set to 0 in which no name is specified
1813 for the construction. The macros odr_implicit and odr_explicit sets name
1814 parameter to zero for the construction involved. New macros
1815 odr_implicit_tag and odr_explicit_tag are similar to the others,
1816 except that a name parameter is added. For programmers' that don't use
1817 ODR they probably only need to change the call to z_APDU and z_External.
1819 Added access control facility by interfacing the TCP wrapper library.
1820 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1821 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1822 name of the daemon and enables the access control as specified in
1823 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1825 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1826 den Dool <H.M.vdnDool@kub.nl>.
1828 Added reference ID parameter to most functions in server API - refer
1829 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1831 Changed name of ccl library to libccl.a (was ccl.a).
1833 Fixed bug in decoder for Explain (Category TargetInfo).
1835 Added support for GNU readline in client. Thanks to Jacob Poulsen
1836 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1838 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1839 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1840 IMPLEMENTATION! This change was made to the development version before
1841 the ZIG decided to retract the amendment. If any users MUST be
1842 compatible with the original Update definition, PLEASE CONTACT US, and
1843 we will include a separate definition corresponding to the old Update
1844 ES. Note that because of the change to the ASN.1 of the
1845 TaskPackageRecordStructure we cannot define a single structure that
1846 will support both versions.
1848 * Added const modifier to buffer parameter for some ODR/BER encoding
1849 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1850 completeWAIS, odr_dumpBER.
1852 Fixed bug in client.c which caused a crash when a scanResponse didn't
1853 contain positionOfTerm.
1855 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1856 * will cause an error in a client if a non-YAZ target sends both a
1857 * list of Scan entries and non-surrogate diagnostics.
1859 Retrieval module enhancements. Tag sets may be typed in the reference
1860 to it. From the .abs-file the "tagset" directive takes a third optional
1861 integer type for the tag set referenced. From a .tag-file the "include"
1862 directive takes a third optional type as well. The old "type" directive
1863 in the tag set itself is still recognized but acts as the default type
1866 Backend interface change. Individual Scan terms returned from bend_scan
1867 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1868 in include/backend.h.
1870 Retrieval module enhancements. Multiple tag sets and attribute sets may
1871 be specified in abstract syntax specs. Revised the error/warning for
1872 logging messages reported by the retrieval module when reading the
1875 Object Identifier system (oid_..) changed. The API is backwards
1876 compatible but the oid-routines now allocates new OID's when needed.
1877 Raw OID's may be specified in oid_getvalbyname.
1879 YAZ now uses GNU configure to generate Makefile(s).
1881 * Minor changes in some of the member names of DeleteResultSetRequest and
1882 DeleteResultSetResponse. See include/proto.h.
1884 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1885 and added member 'languages' in TargetInfo (which was missing).
1887 Changed the way attribute sets are handled in the retrieval
1888 module. These are now cached, just like the abstract syntaxes
1891 Changed YAZ so that it links with compiled ASN.1.
1893 Added Explain-schema definitions and mapping routines. The following
1894 Explain categories have been implemented: AttributeDetails,
1895 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1897 Fixed minor bug in Windows version of Server Library.
1899 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1901 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1903 Added EXTERNAL: UNIverse Resource Report (non-standard).
1905 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1906 ENUMERATED and SET OF.
1908 * Added 'const' to some of the char pointer arguments for the
1909 functions, data1_read_node, data1_getelementbytagname,
1910 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1913 Fixed bug in data1_insert_taggeddata - the last_child member of
1914 parent wasn't initialised.
1916 * Changed data1_read_record and data1_read_node so that the supplied
1917 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1918 doesn't refer to any parts of the "SGML"-buffer.
1920 Fixed bug in server library (Windows version of statserv_remove).
1922 * Changed code so that it compiles as C++. The type definition
1923 of Odr_fun which is a member of Odr_arm was changed. The result is,
1924 that an explicit typecast is needed for the fun pointer when
1925 using Odr_arm - as in:
1926 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1928 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1930 Implemented the new structured date and time definition as approved
1931 by the ZIG. Added schemaId element to the specificTag in Espec-1
1932 (also approved at the last ZIG). Thanks to RVDM.
1934 Added some Object identifiers (RVDM).
1936 Changed the Update Extended Service (RVDM).
1938 Added command "refid" to client which specifies referenceId for
1939 the following requests.
1941 Implemented extended service handling for server. See ztest.c
1942 for an example as well as backend.h. New handlers are registerd
1943 in the Init handler.
1945 * Changed interface for sort in server.
1947 Added new members to statserv_options_block. It allows a server
1948 to read options from another source than just the command line. Thanks
1949 to Charles Woodfield.
1951 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1952 renamed to zboolean. Some C++ compilers complained about the name.
1954 Minor changes to gils.abs. Added index 's' (sort) on title
1955 and date/time-last-modified.
1957 --- 1.4pl2 1998/1/30
1959 Fixed bug in server library regarding inetd mode (-i). This bug
1960 was introduced by release 1.4.
1962 --- 1.4pl1 1998/1/29
1964 Added sort facility in client and backend server interface.
1966 Fixed problem with dependencies in Makefile(s).
1968 Fixed bugs for encoders/decoders of extended services and
1971 Implemented sub-tree feature for schemas. Sub-trees are
1972 referenced in *.abs-files. See explain.abs for an example
1973 of the use of this feature.
1975 Modified bib1.att; local attributes for ANY didn't include
1976 ANY itself (only affects use of the retrieval module).
1978 Fixed bug in plain SGML reader in function data1_read_node:
1979 tags with prefix "var" was incorrectly interpreted as variants.
1981 Added feature "sub-schemas" to enable references to - and definitions
1982 of - group of elements.
1984 * Removed member parent from type data1_element (in data1.h).
1986 Implemented function odr_nullval() that returns the value of
1989 * Removed member num_children from data1_node (in data1.h).
1991 Made NT service interface part of the server library. The
1992 function statserv_main uses the NT service when required and
1993 calls the statserv_start / statserv_close routines.
1995 Routine zget_SearchRequest and zget_PresentRequest fills
1996 resultSetName/Id member with "default" instead of "Default".
1998 Fixed memory leak in server. Request queue member wasn't freed.
2000 Fixed nmem_exit so that memory is freed.
2004 Revised the CCL parser utility to be thread safe.
2006 Added function, oid_ent_to_oid, to replace the function
2007 oid_getoidbyent, which is not thread safe.
2009 * Added nmem_init and nmem_exit to initialize and release
2010 NMEM resources. Function nmem_init should be called once in the
2011 initial thread before NMEM/ODR is used. statserv.c and client.c
2012 have been changed accordingly. The change was necessary to make
2013 NMEM thread safe. The NMEM memory pool is shared amongst threads
2014 in a process. Unix-based applications will still work fine without
2017 Added NT Services interface for the the Z39.50 (statserv) Server.
2018 Refer to the ztest.c source on the usage.
2020 Windows 95/NT port using MSVC5.0. Project files are included in the
2023 * Defined new 'global' handle for the retrieval (data1) system. The
2024 new handled, data1_handle, describes the state of the data1 system.
2025 This handle is passed as first argument to virtually all
2026 data1 related routines. The functions data1_create and data1_destroy
2027 creates and destroys a data1 handle respectively.
2029 Added ODR encode stream member to all backend request structures
2030 init, search, scan etc. This stream should be used to allocate all
2031 memory used for the response when thread safe operation is needed.
2033 Changed the comstack utility, cs_addstr, to be thread safe. The
2034 returned hostname string returned by the function is now part the
2037 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2038 function. The cs_straddr takes a COMSTACK handle as argument, so this
2039 function must be used after cs_create and before bind/connect.
2040 This function is thread safe.
2042 Moved test server to 'ztest' directory - generic server code still
2043 in 'server' directory.
2045 Made prefix query (pquery.c) utility thread safe.
2047 Added new function modifier YAZ_EXPORT to 'export' public DLL
2048 functions when using windows (see include/yconfig.h).
2050 Added definitions to the OID database (util/oid.c) (RVDM).
2052 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2054 Added call to ccl_rpn_delete in client program.
2056 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2057 release of RPN structure.
2059 Added support for C++, headers uses extern "C" for public definitions.
2060 With input from RVDM.
2062 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2063 Thanks to Ronald van der Meer (RVDM).
2065 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2067 Added support for private extensions to the OID database
2068 (oid_setprivateoids()). Thanks to RVDM.
2070 Added optional, physical ANY (key replication)
2072 Fixed null-reference problem in GRS-1 output filter.
2074 Proximity operator added to Prefix Query Format (PQF).
2076 In test client command "base" accepts multiple databases.
2078 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2082 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2084 Smallish bug-fixes in the new encoders/decoders (explain).
2086 Bug fixed in DeleteRequest.
2088 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2090 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2092 Added SOIF syntax (using private OID for now) to retrieval module and client.
2094 Added Update extended service.
2096 Added SearchResult-1 additional info structure.
2098 Added optional CCL (ISO8777) interpreter as separate module. Available
2101 --- 1.2 1996/6/10 (1st anniversary release)
2103 Added Summary record syntax. Lightly tested.
2105 Added OPAC record syntax. Untested.
2107 Added ResourceReport service encoders/decoders. Untested.
2109 Fixed bug in z_Unit - wrong tagging on unitSystem.
2111 Fixed bug in the DiagRecs decoder.
2113 Added options for max PDU size and session timeout to frontend-server.
2115 Added documentation of query-language parsers and other supporting utilities.
2117 [frontend-server] Added Attribute set to the bend_scanrequest API.
2119 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2120 surrogate diagnostics were generated.
2122 [retrieval] Allow multiple local values for attribute.
2124 [retrieval] Allow multiple attributes per element in .abs files. index type.
2126 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2128 --- 1.1pl2 1996/4/10
2130 Minor changes, mostly specific to Zebra's requirements (retrieval)
2134 Repaired bug in frontend server when running multiple listening
2135 endpoints in dynamic mode.
2137 z_External() now won't break if a known, ASN.1 value comes encapsulated
2138 in an octet-string. The value will pass through unmodified in an Odr_oct.
2140 Added a bit of code to the demo client to decode & display
2141 ASN.1-structured records represented in the octet-aligned branch of
2142 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2144 Added z_ext_getentbyref() to the ASN module. Doc updated.
2146 * Completed the SCAN definition in the ASN module. This may break SCAN
2147 code based on older YAZ-versions at compile-time. The fix is easy -
2150 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2151 under the SCAN definition. Remember to initialize this, server-people.
2153 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2154 that this does not extend to ODR and ASN.
2156 Comstack allows insertion of established socket (primarily for
2157 inetd-operation of servers). Doc updated.
2159 Front-end server can now start from the inetd in TCP mode. Doc
2162 --- 1.0pl4 1996/1/24
2166 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2167 the rank and record number.
2169 Adjustments to the frontend server.
2171 Fixed diagnostic BER dumper. It ignored the file argument.
2175 Various changes to retrieval module.
2177 Changed the union discriminators of the protocol files from enums to
2178 ints paired with #defines.
2180 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2183 *Changed operator in the RPN structure to 'roperator', again to avoid a
2186 Fixed problems in Explain decoders/encoders.
2188 --- 1.0pl2 1995/12/6
2190 Memory bug in log module fixed.
2192 --- 1.0pl1 1995/12/5
2194 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2196 Bug in Explain DatabaseInfo module fixed.
2198 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2202 The shift to v1.0 signals that we now consider the *core* functionality
2203 of YAZ reasonably stable (the core being more or less equivalent to
2204 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2205 tested (Explain not at all - though that will happen soonish).
2207 Minor changes to code to support Windows port.
2209 Various minor changes after we're getting to use GRS-1 & co. more.
2211 Added Espec-1 format.
2213 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2214 of the protocol and it cannot be selected when encoding (maps into 'string'
2215 when decoding). Needed to talk to some servers.
2217 Demo client can request simple element set names.
2219 Added Diagnostic Format encoders/decoders.
2221 Added simple Close handling to frontend server (no hooks for resource
2222 reporting yet), and demonstration client.
2224 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2226 --- 1.0b3 1995/08/24
2228 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2229 handled incorrectly when records were requested in the searchResponse. This
2230 will only affect you if you use the frontend-server.
2232 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2233 Test-client will ask for and print GRS1. Ztest will return dummy records
2236 Added Explain encoders/decoders to the service-level API. Untested.
2238 Added Extended Services: Item Order encoders and decoders to the Service-
2239 level API. Untested. We could use a recent copy of the pertinent bits
2240 of the ILL protocol to add those bits.
2242 Added diagnostic format 1 encoders/decoders to the service-level API.
2245 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2246 odr_cons.c, which causes a more correct output.
2248 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2249 was always set to 0 when no records were requested in the searchRequest.
2251 * Added better external-handling. This shouldn't harm old code that
2252 *encodes* externals. It can break code that looks for a
2253 'single-ASN1-type' representation, since those types that are known
2254 are now decoded immediately. Look at the SUTRS sample code in
2255 seshigh.c and client.c. Documentation updated.
2257 Handling of structured records in bend_fetchresponse. Length -1 marks
2258 structured record, type is deduced from format field.
2260 --- 1.0b2 1995/06/27
2261 Fairly quick maintenance release to add SUTRS support.
2263 Fixed handling of SUTRS records in the demonstration client.
2265 * Added format field to the bend_fetchrequest and bend_fetchresponce
2266 structures of the backend API (frontend server). When the record is
2267 returned, the value of the format field is mapped to an OID. The
2268 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2269 of the record. The special value VAL_NONE in the bend_request means
2270 that no specific format was requested by the client. Documentation
2271 updated accordingly. Test server (ztest) will return a fixed dummy
2272 SUTRS record if your client requests SUTRS.
2274 Documentation updated accordingly.
2276 You can now set external libraries and RANLIB support in the top-level
2280 First public release.
