3 Fix description of CCL directive 'case'.
5 More tight checking of form arguments (yaz_uri_to_array). Makes
6 YAZ better at rejecting big and/or bad POSTs.
8 SRU decoding does not report more than up to 10 invalid arguments.
10 rpn2cql: less quotes in generated terms. Semantics unchanged, but
11 it's prettier this way.
15 New utility yaz_decode_init_diag. Defined in proto.h.
17 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
18 given for unix local socket.
19 The COMSTACK string for doing so is:
22 unix:/myfile:tcp:localhost:9999/mybase
23 unix:/myfile:localhost:9999/mybase
24 unix:/myfile:http://fakehost/mybase
26 debian: Use dpkg-buildflags in build process.
30 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
31 global's SRU service uses a recordPosition scheme starting from zero.
32 First record's position should be one
33 according to the standard.
37 Allow more namespaces for SRU. This is to allow, for example, an
38 incorrect namespace returned from server
39 http://services.igi-global.com/sru .
41 Minor fixes for compilation on Windows.
45 daemon: log total number of bad signals from child on stop so that it
46 is more easy to spot problems with child worker processes.
48 retrieval: empty backend name attribute omits element set
49 from being used in retrieval.
53 Implement Solr sort strategy "solr", similar to sru11 sorting.
54 This will implement the correct parameters on Solr requst to do
59 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
62 MARC: Extra/missing indicator handled for MARCXML.
63 The indicator length is given in header and is the same for the
64 whole record. If attributes ind1, ind2 are missing, then content
65 character defaults to blank. Extra indicator attributes (beyond)
66 indicator length are treated as an error.
68 Reformat: delete trailing whitespace
72 MARC: fix non-ASCII characters for leader. This is to ensure we can
73 generate XML in UTF-8.
75 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
76 in one node with structure word.
80 yaz-json-parse: JSON output may be pretty printed by using option
83 Increase default value of max message for Z39.50 Init for GFS, ZOOM
84 and yaz-client. Old value was 1 MB. New value is 64 MB.
88 yaz-client: don't display bogus records from SRU servers. Some SRU servers
89 return more records than given by *maximumRecords*. Skipping those in
92 record_render: simplify buffer return handling and fix at least one bad
93 memory reference, that broke the test_embed_record sometimes.
95 Allow http://user:pass@host notation for yaz_url_exec.
97 zoomsh: allow shell command to be executed. Via the system(3) call.
99 yaz_poll: Allow num_fds == 0
101 yaz-client: fix bad encoding of "itemorder item". The itemorder
102 item <no> - command forgot to use length of encoded Item Request
103 package. Error present since YAZ 3.
105 yaz-ztest: fix bad usage of session handle. Bug was introduced when
106 result sets were saved (271a9c83).
108 SRU recordPacking: guess record packing in response rather than looking
109 at the recordPacking element which, OF COURSE, changed semantics in SRU
112 Decode SRU 2.0 responses. The official namespace for responses, according
113 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
114 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
115 nature.com's server, however, usee namespace
116 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
117 we are now using a glob-expr to match up the namespace. ZOOM C and
118 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
119 I can not find a single real example showing the "real" namespace in
120 the documentation from OASIS. The namespace for requests is different
121 from responses, but this is not added to YAZ yet, when we don't encode
124 --- 4.2.35 2012/06/26
126 zoom/record_render: add support for Base64 decoding fo MARC records
127 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
128 which will decode base64 + ISO2709 marc-8 encoded material from text node
131 --- 4.2.34 2012/06/07
133 Add missing definitions ZOOM_resultset_get_facet_field_by_index
134 and ZOOM_resultset_facets_names.
136 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
139 Change APDU dump printing to avoid long leading blanks. For levels 16
140 or larger the level is shown and the indentation is truncated but
141 recursed with modula 8. This makes it still reasonable easy to read
142 - even for nested BER dumps.
144 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
145 return 0 (incomplete package) in case where the BER package was
146 considered too nested (return value of -2).
148 dumpber: lines of level 15 are not indented further. Two spaces per
149 indentation; indentation 15 or more is indented to a fixed indentation
150 and augmented with a level=<no> indication.
152 zoomsh: increase max size of command+args
154 GFS: No limit in RPN buf size in CQL to RPN conversion.
156 --- 4.2.33 2012/05/09
158 New function for daemon utility, yaz_daemon_stop .
160 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
162 --- 4.2.32 2012/04/25
164 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
165 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
167 --- 4.2.31 2012/04/23
169 YAZ daemon utility relays SIGUSR1 to child process.
171 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
172 would result in en empty database list - which in turn would result in
173 encoding failure for search.
175 Fix reading beyond string in yaz_sort_spec.
177 --- 4.2.30 2012/04/11
179 Add two new SRU diagnostics:
180 236: Access to specified database denied
181 1015: Init/AC: Maximum number of simultaneous sessions for Userid
183 Document the very useful ZOOM-C option "apdulog".
185 CQL to RPN: term may be passed through verbatim. This is enabled with
186 truncation.cql . The assumption being that the term is already CQL.
188 --- 4.2.29 2012/03/20
190 record_conv: leader spec may be given for marc element.
191 The leader spec is given as attribute leaderspec for element marc.
192 For example to convert a MARC21 record from MARC-8 to UTF-8:
193 <marc inputformat="marc" outputformat="marc"
194 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
196 record_conv: allow user-XSLT params. For example:
197 <xslt stylesheet="MARC21slim2DC.xsl">
198 <param name="myparameter" value="myvalue"/>
199 <param name="otherparameter" value="othervalue"/>
202 record_conv: fix error handling for missing marc charsets.
204 CQL: fix extra terms in wrong order.
206 --- 4.2.28 2012/03/06
208 record_conv: modify new API for conversion types. The conversion types
209 may be passed in new functions yaz_record_conv_configure_t and
210 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
212 Avoid mixed statement/variable declare; fixes compilation with Visual
215 --- 4.2.27 2012/02/28
217 Add non-standard SRU diagnostic: 235: "Database does not exist".
218 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
219 Update SRU to Bib-1 diagnostic maps accordingly.
221 CCL: add two new diagnostics for unsupported masking. The new
222 diagnostics are: "Embedded truncation not supported" and
223 "Single charcacter mask not supported".
225 --- 4.2.26 2012/02/23
227 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
229 --- 4.2.25 2012/01/11
231 Build YAZ for Ubuntu Oneiric.
233 CCL: allow parantheses for proximity operands. For example CCL query
234 (a) % (b) is now allowed.
236 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
237 marked dead, rather then being destroyed. If not, the session memory is
238 being free'd before the search/scan handler is finished. Also destroy
239 'request' memory in request_release rather than in various places,
240 which resulted in leaks from time to time.
242 --- 4.2.24 2011/12/21
244 cql_sortby_to_sortkeys: honor sort prefix.
246 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
247 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
248 The rpn2cql family of functions now always returns quoted CQL terms.
250 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
252 --- 4.2.23 2011/12/15
254 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
255 sequence is treated as one. For example, &&a=b&&&c& is identical to
258 --- 4.2.22 2011/12/05
260 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
261 APDUs for a connection to a WRBUF.
263 --- 4.2.21 2011/11/23
265 Fix cql_sortby_to_sortkeys. Completely broken before.
267 Make CCL's @truncation work again.
269 --- 4.2.20 2011/11/09
271 New ZOOM connection setting: tproxy. It's like proxy, but does not
272 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
273 to set resolved address + port for a connection outside ZOOM itself.
275 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
277 --- 4.2.19 2011/11/07
279 Fix uninitialized variable in Solr spell support (could cause SEGV
280 for SRU response decoding).
282 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
283 back-end's addinfo through into the ZOOM response addinfo.
285 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
286 they are separated by a colon and a space rather than simply
289 --- 4.2.18 2011/10/28
291 Add support for Solr spell-checking/suggestions through ZOOM.
292 If a Solr target has been configured correctly for spelling-checking
293 and suggestions, these will now be returned on the ResultSet option
294 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
296 --- 4.2.17 2011/09/28
298 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
299 with a flag whether to substitute escape sequences or not.
301 --- 4.2.16 2011/09/22
303 Fix nmem_strsplit_escape to substitute escape char properly.
305 New option for zoomsh -e , which makes it abort on first error and
306 return process exit code to indicate success/failure.
308 YAZ options utility supports special option -- which makes all it treat
309 all following arguments as non-options.
311 --- 4.2.15 2011/09/16
313 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
314 searched if absolute filename is given.
316 Fix conv_xslt() error-reporting when stylesheet is not found.
317 (The value of fullpath is meaningless in this situation.)
319 --- 4.2.14 2011/09/07
321 Fix problem in CQL sort node creation: un-initialized memory.
323 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
324 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
325 CQL sortby depending on whether Type-1 or CQL is actually sent to the
328 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
329 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
331 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
332 will make it possible to use both single-character mask (#) and wildcard (?)
333 in CCL . Throw diagnostic for left truncation because that is not supported
336 --- 4.2.13 2011/09/01
338 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
339 cases using escapes (\-sequences) and masking.
341 PQF parse fix: A trailing backslash followed by end-of-string (\0)
342 would result in a read one byte beyond string.
344 rpn2ccl may use Z39.50 masking for terms (t=z).
346 ICU check fix. Don't include library -lCrun on Solaris, unless present.
348 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
349 not --cppflags (which seeems like an error in icu-config).
351 --- 4.2.12 2011/08/27 RPM package only
353 cql2ccl: fix conversion of terms: operator characters were not
356 --- 4.2.11 2011/08/25 RPM package only
358 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
359 CCL parser will map both # and ? to their regular expression
360 quivalents (. and .*).
362 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
363 of reserved CQL characters.
365 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
366 is, so that they are passed through.
368 --- 4.2.10 2011/08/24
370 ZOOM SRU mode: more aggressive re-connect.
372 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
373 made available as a utility function, declared in <yaz/logrpn.h>
375 rpn2cql_structure() supports proximity nodes (except that the Type-1
376 proximity node's "exclusion" binary is ignored, as there is no way to
377 express that in CQL). Fixes bug #4564.
381 Fix SEGV that could occur if set command of zoomsh was given without
382 value (2nd argument).
384 Fix SEGV that could occur if unsupported transport was given for
385 COMSTACK - say https (when SSL was unavailable).
387 Build yaz-url on Windows too.
391 New utility to get web content. Header is url.h. A command line tool
392 yaz-url is part of the distribution and packages.
394 Fixes for SSL COMSTACK (when gnutls is in use).
396 New functions yaz_base64{encode,decode}. Header is base64.h.
400 ZOOM C includes HTTP response buffer as additional info if it fails
401 to decode the SRU response.
403 Make wrbuf_json_puts available.
407 zoom: throw diagnostic for invalid value for option "sru". Before a
408 bad SRU request was sent.
410 Adding new utility wrbuf_vp_puts.
412 Add cclxmlconfig.obj to win/makefile. It was missing completely.
416 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
417 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
418 redirect was used at the same time.
420 MARC line mode decoding: be less picky about length given - first
421 5 digits of header that is.
423 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
425 Changes to decoding of SRU records: a record with recordPacking=xml is
426 modified with a new root element <yaz_record> if the recordData contains
427 multiple children elements. This is to make the record XML parseable
430 RPN to SOLR conversion: encode special characters.
432 Generic Frontend Server: fix uinitialized member, stepSize.
436 Fix a bug in SRU decoding of records.. The database records stored
437 had un-initialized memory, but it would only be seen with yaz_record_render
438 and type_spec="ext" .
440 Fix a bug in ccl_qual_dup introduced in 4.2.3.
444 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
448 Add new utilities to convert from CQL to CCL . These utilities have
449 prefix cql_to_ccl defined in cql.h.
451 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
452 lead to memory heap corruptions when ICU utilities were in use.
456 Make compilation work without Libxml2.
458 yaz-client: remove redundant blanks in display of searchResult-1 term
463 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
464 resulting CQL node (tree) in a new node CQL_NODE_SORT.
466 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
467 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
468 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
469 Note that the CQL sortby spec is only converted when the GFS is already
470 converting from CQL to RPN (cql2rpn element).
472 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
473 specify whether to collapse delimitors or not. The existing nmem_strsplit
474 do collapse (collapse parameter = 1).
476 Windows installer: For NSIS, set InstallDir depending on x86/x64.
478 Rename internal func yaz_use_attribute_create. While non-static, this
479 function is not declared in a public header.
483 Add -lCrun when linking with ICU on Solaris.
485 More quicks character set conversions for OPAC records.
489 fix problem with record_render: records were converted (character set
490 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
494 SRU: add methods for handling DADS SRU-proxy facets.
496 Separate OPAC record character set for ZOOM_record. yaz_record_render
497 allows a character set given as charset=from/opacfrom,to where 'from' is
498 the character set of a bibliographic record, 'opacfrom' is character set
499 of OPAC record and 'to' is the target character set.
503 yaz-client: show may XML format records. Command show followed by 'format'
504 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
507 src/stemmer.c: Avoid using unnamed union. It is not supported by some
510 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
513 Update yaz.spec to operate on both SLES11 / Centos 5.5.
515 RPM: Release includes 'indexdata' name. Use indexdata in release name so
516 this package can be distinguished from other vendors.
518 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
519 as determined by configure
521 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
523 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
524 returns no error and no record, the present request is considered
525 partial (only a subset of the records could be returned by backend), and
526 so it is appropriate to set Present Status to partial-4.
530 Move yaz-config man pages to section 1.
532 More documentation about SOLR.
534 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
535 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
536 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
537 peers on some Linux systems. However, in general that does not work
538 so YAZ can not rely on that to work. Debian changed behavior in this
539 respect from Debian lenny to Debian squeeze (still testing as of Oct
541 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
543 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
547 Fix yaz-config output: echo_source not set correctly by configure.
551 SOLR WebService support for yaz-client and ZOOM.
553 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
555 --- 4.0.12 2010/08/17
557 Z39.50 facet support. Facet specifications are passed for search in
558 other-information with ASN.1 as defined in facet.asn and OID
559 .10.1000.81.5 . Facets are expressed as an Attribute list as known
560 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
561 3 is limit (number of entries to get in response). yaz-ztest returns
562 dummy facets if a client asks for them.
564 --- 4.0.11 2010/07/09
566 CCL fixes: bug 2895 and bug 3539.
568 GR1-display: add comma in display - was removed by mistake in
571 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
573 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
575 --- 4.0.10 2010/06/18
577 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
578 result set from a connection. The result set will be on its own
579 thereafter; no operations on it will perform retrievals from a target.
580 Only cached copies are returned.
582 ZOOM C:fix case for HTTP servers responding with Connection:close.
583 Ensure that if there is a current task it is resumed (like fetching
584 more records in a result set) . Bug #3484.
586 PQF parser: use odr_atoi for Odr_int (not atoi)
588 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
589 values that contain any non-digits are treated as string attributes
590 (previously decoding only checked for leading character ([0-9]). PQF
591 encoding: attribute string values are not surrounded by double-quotes.
595 New utility for managing threads - thread_create.h.
597 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
598 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
599 but YAZ' implementation do.
601 Fixes for yaz_cond-functions on Windows 7.
603 DLL export more symbols.
605 zoomsh: show record do NOT render opac.
607 Remove *.la files from Debian and RPM packages.
611 Debian package libyaz-dev depends on libgnutls-dev again (was
612 removed in YAZ 4.0.6, but due to Libtool it is still needed
613 even though yaz-config do not list libgnutls libs).
615 ZOOM: Use only one WRBUF for returning string results for
616 ZOOM_resultset. Reduces memory usage for ZOOM in general.
618 ZOOM: ZOOM_connection do not use a shared pointer to
619 ZOOM_resultset after ZOOM_resultset is destructed by
620 user. Reverts to YAZ 4.0.4 behavior.
624 record-conv: fix problem with at least one XSL conversion -
625 due to probably incorrect usage of XML XSL documents.
629 Fix yaz-config for static mode and the use of SSL (gnutls).
633 Forward decl timeval struct in mutex.h and gettimeofday.h.
635 yaz-config: fix 'static' mode linking.
639 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
640 are wrappers for pthreads or Windows. For Windows these are put in
641 a separate DLL: yaz_cond4.
643 libyaz.la (whole source) is compiled with thread. If thread support
644 is enabled enabled, all source of YAZ is compiled with treading support.
645 This allows core utilities such as yaz_log to use thread facilities.
646 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
647 thread utilities. This commit moves mutex utilities (mutex.c) from
648 libyaz_server.la to libyaz.la.
650 yaz-json-parse displays leading text until error.
654 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
655 patch from Giannis Kosmas.
657 SRU: no longer URL encode SRU database. The URL for an SRU server is
658 a URL and such is alreeady encoded - at least when given with leading
659 http:// or https://. This reverts behavior to YAZ 3.0.50.
661 Support for new MARC XML notation TurboMARC which like MARCXML is a
662 complete representation of MARC/ISO2709.. This one, however, is more
663 compact and allows for faster processing with XSLT. TurboMARC can be
664 used in the marcdisp.h API, from the yaz-marcdump utility and from
667 yaz-ztest can be configured - via the database - to perform certain
668 delays when it performs operations search, present and single record
669 fetch. This allows testers to make yaz-ztest act as a real or even slow
670 Z39.50 server. Refer to the yaz-ztest man pages for details.
674 wrbuf_destroy allows NULL WRBUF passed to it.
676 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
678 Add ZOOM_connection_close.
680 No fixed size buffers for ZOOM shell - bug #3257.
682 tstodr: make it work on s390 platform.
684 New icu iterator-functions. The new icu_iter-functions makes it possible
685 to use ICU chains from many threads.
687 yaz-client: better syntax check for show command.
691 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
694 New simple local-file XML include facility which allows file glob-patterns.
695 Refer to yaz/xml_include.h.
697 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
700 ZOOM_record_get supports new parameter "format" which makes it format XML
703 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
704 JSONText in ECMA-262) is JSONValue, not JSONObject.
708 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
709 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
711 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
712 POSIX/Unix builds .so with major version 4.
714 Remove old LOG_-defines from log.h. They have been obsolete and
715 undefined by default for the last 5 years.
717 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
719 GFS: Remove socket (int *fd) from search_rr handler. The socket
720 descriptor ptr is a facility that allowed a search handler to supply
721 a socket which would serve as a callback - when search was complete.
722 This facility has now been in use for years.
724 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
725 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
726 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
727 returns 'const char *' rather than 'char *. The returned string is
728 read-only and should not be modified by applications. COMSTACK cs_close is
729 now a void function - it no longer returns int. No applications check for
730 the value and the implementations has always returned 0.
732 ZOOM: use size_t for scan hit counts and str size. Functions
733 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
734 occ (hit count) and len (string length) are now of type size_t pointer
735 rather than int pointer. This is to be able to represent large hit counts
736 and to also just to use the proper type for string length (strlen result).
738 New JSON parser. Refer to include/yaz/json.h .
740 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
741 Used to be int in some cases. Many wrbuf_-functions used to return an int
742 indicating some length.. These return values were never used. And so they
745 ODR: odr_malloc, odr_total now takes size_t for size.
747 clone_z_type: fix leak; occurred for encoding failures.
749 --- 3.0.52 2009/12/03
751 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
752 bug was introduced in 3.0.51.
754 --- 3.0.51 2009/12/02
756 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
758 tcpip comstack: fix leak for getaddrinfo.
760 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
761 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
762 Decoding of SRU "path" database is performed by private function
763 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
764 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
766 yaz-client: honor base command for SRU. Change when database setting
767 is applied for SRU and ensure it is kept when a connection is reset.
768 Change also the way errors are displayed or SRU (decoding of packages).
770 --- 3.0.50 2009/11/02
772 Add support for extra request / response data for SRU codecs and GFS.
773 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
774 for extra data response buffer and length. For the GFS, both request
775 and response data (XML) is carried in extra_args and extra_response_data
776 for the search handler. Patch by Ko van der Sloot.
778 ZOOM: For queries that cannot be converted to the specified rpnCharset,
779 ZOOM now returns a diagnostic on the client-side ('invalid query' /
780 10010). This fixes bug #2113.
782 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
783 cmdfile included a 'quit' command that would result in a memory violation.
785 --- 3.0.49 2009/10/01
787 Make a number of functions defined in xmlquery.c static. These have
788 never been declared in a public header file (yaz/xmlquery.h) and was
789 made public by mistake.
791 Improve speed of character conversions (iconv utilities). This makes
792 conversions from MARC-8 faster.
794 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
795 unless type desired is "raw". This will prevent type "xml" from
796 returning ISO2709 .. Which obviously can not be XML parsed.
798 Fix memory leak in ZOOM that would occur if option apdulog was used
799 on a re-used connection.
801 Frontend server logs HTTP requests.
803 Frontend server now sends Z39.50 close when it times out (sesssion has
804 been idle for too long). Versions 2.0.30 and earlier also sent close.
805 But due to a mistake this was disabled in all versions after that, i.e.
806 the server would just close the socket immediately.
808 yaz-client emits a better message when receiving an unrecognised
809 userInformationField.
811 Skip zero-length subfields when decoding ISO2709. This rare case happens
812 if a record has two FS characters in a sequence. Without this patch
813 there would be a reference beyond char array in using_code_len fragments
816 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
818 --- 3.0.48 2009/08/28
820 The show command offered by the zoomsh command now takes a 3d optional
821 parameter type which is what is passed to ZOOM_record. If the type
822 argument is omitted, "render" is used.
824 RPN to CQL conv may use USE string attributes (bug #2978).
826 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
828 --- 3.0.47 2009/07/08
830 Function yaz_xml2query allows a diagnostic element in the PQF XML
831 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
832 code and additional info respectively.
834 The BER BOOLEAN is now the integral type Odr_bool which still happens
835 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
836 typedef'd to Odr_int. This is still an integral 'int', but it may be
837 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
838 ASN-1 compiler as well as programs has been updated to use the new types.
840 --- 3.0.46 2009/06/08
842 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
843 only the bibliographic record was rendered. For type=opac, an OPAC
844 record is only returned if it is present.
846 iconv: small fix for encoding of advancegreek.
848 yaz-client: avoid double display of SRU/SRW records (bug #2798).
850 yaz-client: option auto_reconnect=on really reconnects.
852 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
854 server: avoid null ptr ref for for yaz_poll errors.
856 build: fix RPM build for RHEL 5.3.
858 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
860 --- 3.0.45 2009/03/31
862 Fixed bug #2709: TCP connect returns Invalid argument.
864 Fixed compilation for mingw.
866 Honor charset for raw records (ZOOM_record_get).
868 Fixed use of errno for threaded mode that was seen on Solaris 10.
870 Fixed argument passing with blanks in value for Windows Service.
872 Disable YAZ' own log rotate by default (no 1 GB limit).
873 The variable l_max_size which specifies the log file limit is set to 0
874 (DISABLED): This is due to the fact that YAZ is most often deployed using
875 logrotate. Also YAZ can not perform log rotate because of unsufficient
876 permissions (setuid).
878 --- 3.0.44 2009/02/17
880 List supported encodings in man page for yaz-iconv.
882 Fixed missing SSL libs for --libs output
884 Re-established OID record syntax application-xml. Nobody should use it
885 but we don't want to change soname because of this symbol being absent.
887 --- 3.0.42 2009/02/02
889 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
891 Added member named_result_sets for init handler struct for the GFS. This
892 allows a server to disable named result sets.
894 Removed OID record syntax application-xml.
896 Added support for rule-based transliterator for ICU wrapper of YAZ.
898 Fixed bug #1902: yaz-icu XML output.
900 Make YAZ checks Emacs friendly.
902 BITSTRING value shows value. Bug #2346.
904 ISO2709 decoding: skip control characters from indicator data.
906 Omit sort key by default in yaz-icu's output.
908 Allow combined single char options (again) for YAZ' options function.
910 Utility yaz-marcdump got option to display YAZ version (-V).
912 Allow YAZ to use ICU 3.4.
914 Added new ICU test case which illustrates removal of diacritics.
916 --- 3.0.41 2008/12/29
918 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
920 --- 3.0.40 2008/12/29
922 For configure, using option --without-xml2 also disables Libxslt/Libexslt
925 Fixed bug #2352: yaz-marcdump crashes for certain record.
927 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
929 Added support for Danmarc2 to UTF-8 conversion.
931 Added support for ISO5426 to UTF-8 conversion.
933 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
934 implementation version.
936 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
938 --- 3.0.38 2008/11/10
940 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
941 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
943 ZOOM C now interprets databaseName option for ZOOM connection as path
946 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
948 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
950 Dummy Libxml2 types no longer defined in headers of YAZ'.
952 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
955 --- 3.0.36 2008/09/26
957 Various ODR chapter fixes.
959 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
961 Added missing source for Windows compilation, mutex.c.
963 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
965 For SRU connections in ZOOM all records up to "count" are now fetched.
967 Fixed crash in generic frontend server (and yaz-ztest) which occurred
968 in Windows due to bad error handling for Libxml2.
970 Added facility for sending arbitrary records (ASN.1 any) using
971 ZOOM C's Extended service update. Patch by Sam Reynolds.
973 New options for ZOOM C's connection, logapdu which makes ZOOM log
976 --- 3.0.34 2008/06/18
978 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
980 --- 3.0.32 2008/06/12
982 Fixed memory violation that could occur when decoding UTF-8. This bug
983 was only present in 3.0.30 of YAZ.
985 --- 3.0.30 2008/06/06
987 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
988 GNU TLS is used by default (if found).
990 yaz-ztest returns OPAC records if a client asks for OPAC.
992 Improved speed of MARC-8 encoding.
994 Added support for lossy and loss-less MARC-8 encoding.
996 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
998 Added new Windows Service wrapper (sc).
1000 yaz-client's itemorder command may now send a file.
1002 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1004 Added new function yaz_log_xml_errors.
1006 Allow (but warn) unknown XML attributes in MARCXML parsing.
1008 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1010 The UTF-8 to MARC-8 conversion now uses a different set of characters
1011 for Greek symbols. Bug #2120.
1013 --- 3.0.26 2008/02/21
1015 Added yaz_daemon (daemon.h).
1017 Fixed bug #2068: pkg-config trouble
1019 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1021 --- 3.0.24 2008/01/28
1023 Document --with-xml2 option.
1025 Added OPAC XML XSD (etc/opacxml.xsd).
1027 Allow glob mask for name attribute in retrieval element for the
1028 generic frontend server's retrieval facility.
1030 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1031 except POLLIN/POLLOUT.
1033 Fixed error handling in cs_listen. Bug #2037.
1035 --- 3.0.22 2008/01/20
1037 Fixed version in yaz/yaz-version.h.
1039 Fixed bug #2027: Crash when closing connection.
1041 Changed configure so that ICU support is only enabled if only ICU
1042 and Libxml2 is available (because the ICU chain is XML based).
1044 --- 3.0.20 2008/01/15
1046 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1047 is built. Only this DLL depends on the ICU runtime.
1049 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1050 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1052 Changed license of CCL module to 'Revised BSD'. After consultation with
1053 remaining members of the original EUROPAGATE consortium, we are re-issuing
1054 the CCL module without a separate license. The software was developed by
1055 Index Data as part of a research project. The special license was included
1056 to help feed usage information back to the project consortium to support
1057 project evaluation. At this time, the project consortium has long-since
1058 disbanded, and the majority of the original principals have retired. At the
1059 same time, we have significantly modified the software during the following
1060 years, to the point where very practically no original code remains. To
1061 simplify re-use of the software, we have contacted those members of the
1062 consortium who could be reached, and agreed to re-issue the module as a
1063 proper part of the YAZ package.
1065 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1067 CQL closer to being version 1.2 compliant. CQL also allows free-form
1068 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1071 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1072 bug could make Extended services handling crash in the ZOOM layer. This
1073 bug was only present in YAZ 3.0.18.
1075 --- 3.0.18 2007/12/19
1077 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1080 yaz-marcdump reads and writes collection wrapped records.
1082 Handle OPAC for record conversion module.
1084 Fixes for ICU wrapper.
1086 Allow ICU libs to be controlled with --with-icu .
1088 --- 3.0.16 2007/11/12
1090 Added yaz_poll which is a wrapper for select/poll. When poll is available
1091 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1092 sockets to be in use.
1094 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1095 functionality through an XML based configuration (ICU chain). This system
1096 is useful for search facilities such as Pazpar2 and Zebra that needs to
1097 perform tokenization of indexed material. The ICU code in a separate
1098 library libyaz3_icu.a.
1100 Added HTTP tunnel facility for COMSTACK, bug #1752.
1101 This is a facility that allows a Web proxy, such as squid, to tunnel
1102 Z39.50 traffic. This facility is "transparent" to must applications
1103 using YAZ. It's enabled by using pseudo transport connect: followed by
1104 the proxy address, followed by command, then follwed by he regular
1105 "virtual" addresss. For example,
1106 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1108 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1110 --- 3.0.14 2007/09/21
1112 Fixed bad memory reference in ZOOM_record - cuased by member not being
1113 initialized. This was a problem only in YAZ 3.0.12.
1115 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1116 fields were not removed.
1118 Changed the way C code is generated from codetables.xml. Made a MARC-8
1119 conversion trie for each characterSet section rather than codeTable.
1120 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1121 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1123 --- 3.0.12 2007/09/12
1125 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1126 from ZOOM_record_error).
1128 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1130 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1132 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1134 Better SRW-to-Bib-1 diagnostic mapping.
1136 ZOOM C and yaz-client announces SRU version 1.2 by default.
1138 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1141 Fixed in yaz_sru_decode to allow other version than 1.1.
1143 --- 3.0.10 2007/08/22
1145 Added support for SRU scan for ZOOM.
1147 Added support for the use of the older versions or Extended Service
1148 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1149 set to the version , 1=first, 2=second, 3=third. The third version is
1150 what ZOOM C has used so far. And that, obviously, is the default.
1152 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1153 therefore in Zebra and in SimpleServer-based applications). The new
1154 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1155 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1156 which is passed into the back-end search callback function.
1158 Added support for HTTP Basic authentication in clients: the SRU/W
1159 codec encodes the username/password elements of the PDU structure
1160 appropriately, and these may be set using the "user" and "password"
1161 options in ZOOM-C applications (the same options that are used for
1162 Z39.50 authentication).
1164 --- 3.0.8 2007/06/25
1166 Fixed bug #1208: SSL appears to be broken in ZOOM.
1168 Fixed bug #1206: Libxml2 include path weirdness.
1170 Added oid_name_to_dotstring.
1172 Allow elementSetName to be specified for ZOOM C record update.
1174 Allow waitAction to be specified for ZOOM C based for Extended Services.
1176 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1177 syntax OID. Bug introduced in YAZ 3 series.
1179 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1181 --- 3.0.6 2007/06/06
1183 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1184 directory. yaz-client now reads commands from file given by option -f
1185 if specified; then tries to read .yazclientrc in current directory.
1186 Failing that, it reads .yazclientrc from user's home directory.
1188 Added support for correlationInfo Note and ID for Record Update via
1191 Added yaz-client command querycharset which specifies character set for
1192 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1193 (termListAndStartPoint).
1195 Charset ISO5428:1984 is an alias for ISO5428-1984.
1197 Implemented a way to perform scan in a result set using Z39.50. This
1198 is achieved by attaching the result set name in the characterInfo
1199 (type InternationalString) of OtherInformation in the Scan Request PDU.
1200 The result set is identified in the otherinformation by the new OID:
1201 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1202 This allows for scan in result set and faceted search . Zebra did some
1203 of this in the APT term using attribute type 8 and value being result
1204 set. Using the OtherInformation approach for this is cleaner and easier
1205 to work with in proxies and the like. This facility can be used in
1206 yaz-client using new command setscan which takes a result set as first
1207 argument, start position (APT) as second.
1209 Changed decoding of SRU XML packed records to deal with servers that
1210 have recordData with XML data with multiple root nodes. Also make
1211 comparison for recordPacking case insensitive. Again, one server
1212 returns "XML" where others return "xml".
1214 For SRU responses allow Content-Type application/xml as well as text/xml.
1216 --- 3.0.4 2007/05/21
1218 Fixed bug in character set conversion of BER strings. Bug introduced
1221 --- 3.0.2 2007/05/08
1223 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1225 For OID class, use oid_class consistently.
1227 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1230 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1231 character set for bibliographic information interchange". By Giannis Kosmas.
1233 Added documentation on new OID API.
1235 --- 3.0.0 2007/05/02
1237 Changes to generic frontend server interface: added new member
1238 'query_charset' for bend_initrequest structure. A backend init handler
1239 should set this member to its native character set for query terms.
1240 When defined, the frontend server logic will announce this character set
1241 to a client if the negotiationModel bit is set by the client. All server
1242 implementors are encouraged to specify this. If a backend server does not
1243 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1245 Added CCL utility to remove terms (stop words) from resulting RPN
1246 tree. This is handled by functions with prefix ccl_stop_words_ .
1248 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1249 terms in RPN queries.
1251 Clean-up the CCL API. Moved some internal structures from ccl.h to
1252 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1253 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1254 This is replaced by ccl_parser_find_str which takes a string instead.
1256 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1257 libyaz.la is the core of YAZ except the generic frontend server and
1258 does not depend on POSIX threads anymore. libyaz_server.la is the
1259 generic frontend server facilities and uses POSIX thread functionality
1260 if available. The libyaz.la no longer depends on POSIX threads because
1261 the number of global structures is limited. NMEM no longer re-uses blocks
1262 between threads ; it simply free's memory immediately but allocates in
1263 "large" chunks as usual. We don't expect any performance penalties
1264 because of this. The yaz_log system is still using a global log_level so
1265 caution must be taken when modifying it with yaz_log_init_.. +
1266 yaz_log_mask_str. This, however, should not cause any trouble because
1267 these functions are called during initialization of application code
1268 anyway. `yaz-config --libs server` returns libs for server applications;
1269 `yaz-config --libs` returns libs for non-server applications.
1271 New OID database - with public definitions in oid_db.h. Removed old OID
1272 database including the head oid.h and definitions such as enum oid_value
1273 and struct oident. The new OID database uses the same string names as
1274 before but the 'protocol' is gone. There are now only two representations
1275 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1276 converts from string to OID; functions with prefix yaz_oid_to_string
1277 converts the other way.
1279 Change to emit_term() in CQL-to-PQF query translation: when a term has
1280 the /regexp relation modifier, do not process it for leading and
1281 trailing "^" and "*", which have quite different meanings in regular
1284 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1285 write handlers no longer carries a 'last' parameter. This will make
1286 yaz_iconv flush "less" characters. A flush is performed by call to
1287 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1289 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1290 removed, because function yaz_query_to_wrbuf does the same.
1292 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1293 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1295 Deprecated MARC utility functions removed.
1297 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1300 Branch split: YAZ_2_1_55_branch
1302 --- 2.1.54 2007/03/16
1304 Fix to ZOOM-C so that transparent reconnection is properly handled on
1305 connections that are in asynchronous mode.
1307 Fixed compilation on OpenBSD 4.0.
1309 Large strings in GRS-1 records are now properly displayed in yaz-client.
1311 Added character conversion support for "advancegreek"; based on patch from
1314 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1315 sequence is met. Before the error was not set so it would be unknown.
1317 Adjust yaz-marcdump MARC reader so that it skips until record separator
1320 --- 2.1.52 2007/03/07
1322 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1323 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1324 fd_set structure used as a bitmask for the FDs to be selected on.
1326 Using ACX_PTHREAD macro to check for POSIX threads.
1328 Fixed have-vsnprintf check.
1330 --- 2.1.50 2007/02/23
1332 Fixes for configure on BSD. Bug #900.
1334 Added snprintf/vsnprintf wrappers for systems that don't have
1335 limits (heavens forbid).
1337 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1338 created before all previous tasks were completed and removed from the
1339 task queue, the new task could be removed by a mistake.
1341 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1343 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1345 Fixed bug #832: Problem with MARC/charset in yaz-client.
1347 Fixed bug #668: save command line history for yaz-client.
1349 Fixed bug #830: pkg-config support.
1351 --- 2.1.48 2007/01/23
1353 Extended ZOOM result set options with two options that may be read by
1354 a client: resultSetStatus and presentStatus with values as specified for
1356 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1358 Fixed bug #827: Using SSL fails on Debian etch.
1360 Fixed bug #826: Weird looking chars for set of MARC records.
1362 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1363 that is treated as an ItemOrder with itemRequest being an XML document
1364 external. The value of "doc" is the content.
1366 Extended the GFS search facility. New member of bend_search_rr
1367 'estimated_hit_count' signals that hits is known to be an estmate
1368 (higher or lower than real hit count). New member 'partial_resultset'
1369 signals that the search was partial (hit count is lower or equal than
1370 real hit count). For Z39.50, the information is stored in resultSetStatus
1371 member of SearchResponse APDU. For SRU, the information is signalled
1372 via SRU diagnostic 59: "Result set created with valid partial results
1375 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1377 --- 2.1.46 2007/01/13
1379 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1381 Added ZOOM_connection_peek_event.
1383 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1384 the following new functions:
1385 ZOOM_event_nonblock, ZOOM_connection_process,
1386 ZOOM_connection_get_{socket,mask,timeout},
1387 ZOOM_connection_fire_event_{timeout,socket}.
1388 The existing blocking event handler, ZOOM_event, is a wrapper for the
1389 + blocking ZOOM_event_sys_{poll,select}.
1391 Implemented function ccl_xml_config which parses XML version of CCL
1392 configuration (bug #798).
1394 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1396 Added timings utility (yaz/timing.h)
1398 --- 2.1.44 2007/01/03
1400 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1403 Fixed bug #779: Rotation of apdu.log fails.
1405 Fixed for character set conversions:
1406 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1407 Honor G1 set in MARC-8 decoding.
1409 --- 2.1.42 2006/12/17
1411 Fixed bug #775: char conversion does not handle Alternative UTF-8
1414 Implemented function yaz_marc_read_line which parses MARC line format
1415 records. There is a wealth of formats out there. So far, this function
1416 reads line records produced by yaz_marc_write_line.
1418 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1419 more generic and easier to remember(!) options: -i format and -o format
1420 which specifies input format and output format respectively - where
1421 format is one of "marc", "marcxml", "line", "marcxchange".
1423 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1424 does not print anything except warnings for records.
1426 For yaz-marcdump, added support for MARC split into files (-s) with a given
1429 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1430 spec, at http://www.loc.gov/standards/sru/record-update/
1431 This has changed the binary layout of the following structs:
1432 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1433 bend_update_rr . Patch by Ko van der Sloot.
1435 Added GFS utility function bend_assoc_is_alive which returns 1 if
1436 association is still alive (client is connected); 0 otherwise (client
1437 closed connection). This allows busy servers to stop working for
1440 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1441 been a separate piece of software. This version of ziffy has been modified
1442 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1444 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1446 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1447 Client code may now interrogate options such as "init_opt_sort" to
1448 find out whether the server claims to support various options.
1450 --- 2.1.40 2006/11/27
1452 Added utilities yaz_{set,get}_esn to set/get element set name from
1455 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1456 of YAZ and has been so since YAZ 2.1.10.
1458 Implemented ZOOM_record_error which returns error information for
1459 record (surrogate diagnostic).
1461 --- 2.1.38 2006/10/31
1463 Updates for SRU Update by Ko van der Sloot:
1464 1. Changed name from "operation" to "action"
1465 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1466 versions in the code, marked as 'backward compatible'.
1467 3. Added diagnostics for SRU Update.
1469 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1471 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1473 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1475 For GFS, fixed problem with SRU diagnostic 'First record position out of
1476 range' being issued for 0 hits.
1478 zoomtst10 part of Windows Build.
1480 --- 2.1.36 2006/10/13
1482 Implemented yaz_filepath_comp which splits a path into file path
1483 components (required by Zebra 2.0.3+).
1485 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1486 BSD inspired license until now so this should not have any real impact on
1487 anybody. See http://www.opensource.org/licenses/bsd-license.php
1489 Fixed bug #687: Missing log lines.
1491 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1494 Fixed bug #689: SRU diagnostics to be added.
1496 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1497 whether a connection is idle (no more work do do).
1499 --- 2.1.34 2006/10/04
1501 Change type of optval from long to int for invocation of setsockopt with
1502 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1504 Added support for specifying the max log file size for the Generic
1505 Frontend Server. The size is given with option -r.
1507 --- 2.1.32 2006/09/21
1509 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1511 --- 2.1.30 2006/09/17
1513 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1516 Fixed bug in Generic Frontend Server that could cause a server to stop
1517 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1519 For the generic frontend server, the maximum record size is used as maximum
1520 size of incoming packages (SRU + Z39.50). The value until was previously
1521 only used in Z39.50 Init negotiation and, later, in a session controlled
1522 sizes of records returned. This is controlled using -k option. It can be
1523 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1525 --- 2.1.28 2006/09/04
1527 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1530 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1532 New option for yaz-marcdump -lpos=value which allows setting a portion
1533 of MARC header to a certain value.
1535 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1537 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1538 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1540 --- 2.1.26 2006/08/15
1542 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1545 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1547 --- 2.1.24 2006/08/08
1549 Fixed MARC ISO2709 encoding routines to deal with character set
1552 Minor changes to GFS logging. Database included in search request log
1555 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1556 cached/multiple records.
1558 Shared libraries are built by default on Unix+configure.
1560 Changed cql2pqf transformation to use a different evaluation order. The
1561 new order is: always, relation, structure, position, truncation, index
1562 and relationModifier. Old order was: always, relation, relationModifier,
1563 structure, index, position, truncation. Note that the the latter ones
1564 override former ones for identical attributes.. The new scheme means that
1565 it is possible to override any existing attribute with a relationModifier.
1566 And also that it is possible to override everything for the index rule
1567 (except the ones listed in relationModifier). No order is perfect but this
1568 one, we believe, covers more real cases.. The "always" should have been
1569 called "default", since the attributes there can be overridden with all
1572 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1573 compilation phase, but also for yaz-config --cflags output. This allows
1574 us to have public headers with Libxml2 stuff in them . It should also,
1575 eventually, make Libxml2 checks redundant in packages using YAZ, such
1578 --- 2.1.22 2006/06/15
1580 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1581 stored in uri, message and details.. Previously diagnostics were stored
1582 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1583 compatibility.. but he's probably the only one affected, so.
1585 Added support for CCL, compiled on the client side, in ZOOM-C. This
1586 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1587 input; the resulting query objects can be used for for searching with
1588 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1590 YAZ' configure searches for OpenSSL by default.
1592 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1593 SL_CTX_use_certificate_file. See
1594 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1595 for more info. Thanks to Ko van der Sloot.
1597 --- 2.1.20 2006/06/02
1599 Bug #600: SRU GET, POST support for yaz-client. Introduced
1600 command 'sru' which selects method SOAP/GET/POST.
1602 Allow missingValueAction to be specified for the sortspec string -
1603 function yaz_sort_spec. By default, the missing value action is null.
1604 Use ! to specify "abort". Use = followed by stringvalue to specify default
1607 Ensured that Present-handler (if defined) is called in GFS before any call to
1608 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1609 searchRetrieve requests.
1611 Documentation for YAZ is now based on the Docbook XML/XSLT using
1612 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1613 is no longer depending on jade/openjade or docbook-to-man scripts.
1614 PDF is no longer part of the distribution - but can optionally be
1615 made using DSSSL/jadetex or FOP.
1617 Added retrieval handling support in Generic Frontend Server to support
1618 conversion between MARC/XML as well as XSLTtransforms. See
1619 etc/yazgfs.xml for an example.
1621 Added Authentication support to Generic Frontend Server in SRU
1622 mode. Authentication using HTTP Basic is supported, as is the use
1623 of 'x-username' and 'x-password' parameters in the request itself.
1625 Added support for a new character set MARC8s identical to MARC8 except
1626 that it converts combined characters to single Unicode characters in the
1627 Latin-1 range (when possible).
1629 --- 2.1.18 2006/04/24
1631 ASN.1 compiler 0.4: generates brief Doxygen file header for
1632 generated .h/.c files.
1634 Utility yaz_iconv now supports conversion to MARC-8.
1636 New facilities for the MARC module. The reading - and writing of
1637 content are separate methods for the yaz_marc_t handle. The following
1638 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1639 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1640 format). Write functions have prefix yaz_marc_write_.. The existing
1641 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1642 available. Removed support for OAI-MARC and simplexml (not the
1643 simplexml from PHP5).
1645 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1646 to be returned for this connection.
1648 --- 2.1.16 2006/03/31
1650 Allow multiple languages and charsets to be specified with
1651 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1652 negcharset iso-8859-1,utf-8
1654 Translation of proximity nodes from CQL into PQF now works.
1656 Moved to automake 1.8, 1.9.
1658 Added function yaz_log_set_handler which allows a log handler to be
1659 installed. This handler will be called for all log messages. Output
1660 to file is also produced; but that can be disabled by passing NULL
1661 fname to yaz_log_init_file.
1663 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1665 For SRW (including GFS), accept application/soap+xml as content-type
1668 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1669 produces NO stylesheet reference even if a default stylesheet is specified
1672 --- 2.1.14 2006/03/14
1674 Updated Windows package to include yazd.dll + yazd.lib for the
1675 Development component.
1677 If the environment variable YAZ_LOG is set, then it is used as a
1678 string indicating the default level of logging to use if not
1679 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1680 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1681 used as before. So, for example, to omit warnings from YAZ logging,
1682 export YAZ_LOG=-warn
1684 cql_transform() now map structure and other attributes before indexes,
1685 so that index-specific structures and other attributes can override
1686 defaults. So now a combination of mapping specifications such as:
1688 index.dc.date = 1=date-modified 4=5
1689 does the right thing.
1691 cql_transform() now also respects the "always" mapping specification,
1692 which establishes an initial set of attributes to be used for all
1693 terms except where overridden by more specific attributes associated
1694 with the index, relation or modifier.
1696 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1697 which mode to use; one of "post", "get" or "soap" (SRW, default).
1699 Fixes for yaz_iconv routines: changed trie-based character set conversions
1700 to use only non-negative values for bit fields due to Sun's C compiler not
1701 supporting negative values.
1703 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1704 sequences where not read correctly. Fix by Rustam Usmanov.
1706 Updated win/makefile to use options, settings which makes things
1707 compile with VS C 2005.
1709 --- 2.1.12 2006/02/01
1711 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1713 In ZOOM socket code, use select instead of poll on MacOSX.
1715 ZOOM-C now support client-side compilation of CQL into RPN that is
1716 sent to the server, enabling CQL to be used against all Z39.50
1717 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1718 ZOOM_query object, and submit it using ZOOM_connection_search().
1719 The CQL-to-RPN translation uses a configuration file, the name of
1720 which must be specified in the Connection's "cqlfile" option.
1722 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1723 function, which takes as its start-term parameter a ZOOM_query object
1724 (which may have had either CQL or RPN set into it).
1727 --- 2.1.10 2005/11/29
1729 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1730 GFS to support this as well. Backend handler, bend_srw_update, does the
1731 update work. Code contributed by Ko van der Sloot.
1733 Allow retrieval of Search Result-1 information in ZOOM by the use of
1734 options that are attached to a result set. ZOOM documentation updated
1737 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1738 UTF-8 conversion. Patch by Raj Patel.
1740 Added option -m to GFS to control formatting of timestamps in log file.
1742 Added 'exit' as synonym for 'quit' in yaz-client
1744 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1745 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1746 for the new members. Patch by Ko van der Sloot.
1748 Added support for SRU POST. It is supported for content-type
1749 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1751 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1752 Instead make the library libyaz.la multi-threaded. Threading as a whole
1753 can still be disabled by configure option --disable-threads. Previosly,
1754 with older GLIBCs there were problems with MT libs under Apache. This
1755 has now been fixed a long time ago.
1757 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1760 CQL module modified to be case insensitive for relations/indexes/operations.
1762 Fixed bug in CQL transform code: incorrect value relationModifieder
1765 Added 'show all' command for yaz-client which retrieves all results
1768 Added new yaz-client, xmles, which takes a (private) OID and
1769 a document to be sent as an extended service request.
1771 Describe new yaz-client commands wait_response and set_auto_wait.
1773 Increase TCP/IP listener backlog from 3 (which I am guessing was
1774 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1775 that the socket will queue as many incoming connections as it's able
1776 to handle ongoing connections. In other words, it will never now
1777 refuse a connection that it would be able to handle merely because
1778 it's not got around to accepting() enough of the pending connections
1779 yet. This is the behaviour anyway under Linux, where the listen()
1780 argument is ignored; but not under BSD and on systems such as
1781 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1782 YAZ-based servers should now be uniform across operating systems in
1785 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1786 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1787 This allows yaz-marcdump to read large MARC batches (>2 GB).
1789 Modified all YAZ source files - except the source which is auto-generated
1790 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1793 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1794 corresponding to the existing *_setl() function. These allow option
1795 values containing arbitrary valuues.
1797 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1798 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1799 except that it returns an indicator of whether or not the sort
1800 criterion was accepted (0 for OK, -1 for invalid).
1802 --- 2.1.8 2005/06/07
1804 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1805 MARC output rather than returning "new" buffer.
1807 yaz-client warns about unknown init options.
1809 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1811 --- 2.1.6 2005/05/24
1813 Added support for SRW sort in Generic Frontend Server. Patch
1814 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1815 sortKeys - or NULL if none is provided.
1817 Fixed bug #307: It was impossible to specify indefinite/no timeout
1818 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1821 Added support for multiple languages and charsets to be specified in
1822 ZOOM. Each charset/language is separated by a blank. If negotiation is
1823 in effect in init-response, Option
1824 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1825 Code based on patch by Vasiliy Osadchuk.
1827 Fixed bug #306: infinite recursion that occurred when calling
1828 yaz_log_level_init as the first call (before other log level or
1831 Fixed bug in scan handling in front end server: if preferred-Position-In-
1832 Response was non-present, a NULL pointer referece was performed.
1834 --- 2.1.4 2005/04/26
1836 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1837 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1838 now defined for all those error codes. So instead of putting 109 in
1839 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1840 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1842 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1845 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1847 Program yaz-client now exits and produces an error message if multiple
1848 Z39.50 servers are specified on the command line (none or one allowed
1851 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1854 --- 2.1.2 2005/03/16
1856 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1858 Fixed bug #272: Preserve spacing for CCL terms.
1860 --- 2.1.0 2005/03/14
1862 Added support for virtual hosts and multiple backend servers for
1863 the YAZ frontend server. The configution is XML based and
1864 support specificition of CQL to RPN mappings and explain information.
1865 See section "Virtual Hosts" in the YAZ manual.
1867 Extended OPAC display utility. OPAC display utility renders
1868 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1869 to supplement yaz_marc_decode_wrbuf.
1871 Fixed a bug in MARC decoder that could caused it to crash for some
1872 invalid MARC records. More diagnostics and warnings where added in
1873 XML output (warnings, etc are stored in comments).
1875 --- 2.0.34 2005/02/08
1877 Fixes for UNIX domain sockets. Bug #261.
1879 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1881 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1882 Added yaz_marc_subfield_str which defines subfield lead string which is
1883 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1884 yaz_marc_endline_str which defines end of fields string used in
1885 YAZ_MARC_LINE format. Default string is newline.
1887 Experimental support for MarcXChange. This format can be produced
1888 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1889 http://www.bs.dk/standards/MarcXchange.xsd
1891 Added yaz-client commands scansize that sets maximum number of
1892 entries to be returned by scan.
1894 --- 2.0.32 2005/01/11
1896 Added support for SRW scan in yaz-client and Generic Frontend Server.
1898 * Added whereInList member to SRW Scan Term.
1900 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1902 Fixed NMEM system to return aligned blocks on the smallest boundaries
1903 that are suitably aligned for all possible types on the particular
1904 architecture YAZ is being built for.
1906 --- 2.0.30 2005/01/04
1908 Fixed numerious warnings that was issued with newer versions of GCC.
1910 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1911 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1914 Make YAZ Generic Frontend Server slightly faster.
1916 Enhance (and reduce) logging for Generic Frontend Server.
1918 Revert YAZ log system so that it flushes every write operation
1919 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1921 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1922 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1923 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1924 will effectively disable old definitions.
1926 --- 2.0.28 2004/11/09
1928 Added yaz_log_time_format which specifies log format using
1931 Added yaz_log_module_level which returns mask for a module. Value
1932 is non-zero mask a if module is enabled; zero if disabled.
1934 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1935 in include/yaz/cql.h.
1937 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1939 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1941 Fixed bug #172: RPM builds does not enable SSL.
1943 Doxyfile.in part of dist. Doxyfile generated by configure.
1945 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1946 are given and the corresponding component does not exist.
1948 Extend CCL documentation in YAZ reference. Describe r=r.
1950 --- 2.0.26 2004/10/01
1952 Fixed MARC->MARCXML conversion to properly deal with
1953 fields, subfields, indicators having non-ASCII characters.
1955 Fixed MARC->MARCXML conversion so that ASCII control characters
1956 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1959 Added YAZ GFS support for conversion from Z39.50 surrogate
1960 diagnostics to SRW surrogate diagnostics.
1962 Bug fix: YAZ GFS did not return schema in explainResponse.
1964 --- 2.0.25 2004/09/30
1966 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1967 now converts recordSchema to elementSetName as well as schema URI.
1969 Fixed bug in COMSTACK that prevented HTTP request packages from being
1972 --- 2.0.24 2004/09/29
1974 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1975 does not require white-space before and after the dash in a range, e.g.
1976 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1979 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1980 due to new GCC removing "redundant" code.
1982 Added yaz-client commands scanpos and scanstep that sets preferred
1983 position and step-size for scan.
1985 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1987 Added CCL utility ccl_qual_buf which parses one or more CCL
1988 spec lines in a buffer.
1990 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1991 of name and value - ignoring empty lines and comments.
1993 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1995 Added odr_get_element_path which returns current element path for an
1996 ODR handle. This utility is useful in error handling or user-defined
1999 Added ODR_PRINT utility odr_set_stream which is is a more generic
2000 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2001 to a write function and pointer to close function. The close function - if
2002 non-NULL - will be called during odr_destroy.
2004 Fixed bug in CCL parser where truncation char was not removed from
2005 right side when truncation=both was in effect.
2007 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2010 --- 2.0.23 2004/08/11
2012 Fix buffer overrun in CQL parser when dealing with proximity (%).
2014 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2015 to UTF-8/UCS conversion is now only based on codetables.xml.
2017 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2019 --- 2.0.22 2004/08/06
2021 Add support for more "commit changes" in ZOOM (uses Extended Services).
2023 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2026 Yet another small fix for configure of SSL.
2028 --- 2.0.21 2004/05/14
2030 Fix SSL libs for configure when --with-openssl=DIR is given.
2032 --- 2.0.20 2004/05/10
2034 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2036 SSL comstack now uses yaz.pem certificate file on server side
2037 by default. Certificate filename can be configured by calling
2038 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2040 Fix bug regarding multiple calls to ZOOM_connection_connect.
2042 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2044 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2045 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2047 ZOOM now allows inspection of X509 peer certificate for verification.
2048 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2050 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2051 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2052 as "modular" but it simplifies things.
2054 Added cs_get_peer_certificate to that returns peer X509 PEM.
2056 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2057 NULL if SSL is unavailable.
2059 Documentation about MARC decoding tools.
2061 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2063 --- 2.0.19 2004/03/30
2065 Rename CHANGELOG to NEWS to follow GNU style packing.
2067 Fix bug with missing initialization of member in init_diagnostics.
2068 This bug affects threaded version of GFS server.
2070 --- 2.0.18 2004/03/20
2072 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2075 Ensure zlib.dll is packed with Windows install.
2077 --- 2.0.17 2004/03/17
2079 Fix encoding of xsd:string to use text instead of CDATA.
2081 Fix endless loop in CQL parser with unbalanced ".
2083 Use a more compact way to store MARC-8 conversion tables.
2085 --- 2.0.16 2004/03/16 Debian only
2087 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2090 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2095 --- 2.0.15 2004/03/01
2097 Another fix for decoding of XML packed records.
2099 --- 2.0.14 2004/02/25
2101 Fixes for Chunked encoding. White space not ignored after length spec.
2103 Update NS and use default NS for SRW diagnostic elements.
2105 --- 2.0.13 2004/02/23
2107 Implement ZOOM_resultset_cache_reset which resets record cache.
2109 Implement ZOOM_resultset_sort which sorts a result set.
2111 Implement chunked HTTP transfer.
2113 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2115 --- 2.0.12 2004/02/16
2117 Added member 'schema' to bend_explain_rr structure so that backend
2118 can specify explain record identifier. Defaults to Zeerex 2.0.
2120 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2122 --- 2.0.11 2004/02/16
2124 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2127 Added init command for yaz-client which sends "extra" init request.
2129 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2130 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2132 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2134 Make ZOOM error code for "invalid query".
2136 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2138 --- 2.0.10 2004/02/05
2140 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2143 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2145 Added option -p <file> to make Generic Frontend Server to write PID file.
2147 Added option -D to put Generic Frontend Server in background on its own.
2149 Make ZOOM C recognize option "password". If unset, "pass" is used
2150 (for backwards compatibility).
2152 Fixed a bug in Generic Frontend Server that could make it crash if a
2153 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2156 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2157 Must be issued before open, in order to be in effect.
2159 --- 2.0.9-6 2004/01/12 Debian/Windows
2161 Make the SRU server more picky WRT unknown params, etc.
2163 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2165 New YAZ client command, options, that sets Z39.50 options.
2167 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2168 options from a string of tokens (one token for each option bit).
2170 Update SRW diagnostic code messages.
2172 --- 2.0.9-5 2004/01/07 Debian/Windows
2174 Handle user defined stylesheet for SRW/SRU.
2176 --- 2.0.9-4 2004/01/06 Debian/Windows
2178 Fix bug in decoding of Content-Length.
2180 --- 2.0.9-3 2004/01/06 Debian/Windows
2182 Fix a bug with decoding of XML packed records.
2184 --- 2.0.9-2 2004/01/05 Debian only
2186 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2188 Fix bug in SRW/SRU diagnostics decoding.
2190 --- 2.0.9 2004/01/05
2192 Fixed bug in Generic Frontend Server which could drop records exceeding
2193 preferred message size. Reported and fixed by Irina Dijour.
2195 Fixed calculation of package size for structured records in Generic
2196 Frontend Server. Reported and fixed by Irina Dijour.
2198 Fixed namespace for SRW/SRU diagnostics.
2200 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2202 --- 2.0.8 2003/12/22
2204 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2205 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2208 CQL changes to reflect recent changes to the specification:
2209 * Documentation talks about context sets instead of index sets.
2210 * Documentation talks about indexes instead of qualifiers.
2211 * The CQL-to-PQF transformer's configuration file now uses
2212 "index.set.name = <attributes>" instead of the old form
2213 "qualifier.set.name = <attributes>". (Both forms are still
2214 understood but the latter is deprecated.)
2215 * CQL terms with no explicit index specified are now interpreted as
2216 cql.serverChoice instead of srw.serverChoice (which of course
2217 behaves exactly the same.)
2219 --- 2.0.7 2003/12/16
2221 MARC conversion can now generate ISO2709 output in another
2222 character set. yaz-marcdump uses this facility if you invoke it
2225 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2226 functions from there can be used from C++.
2228 --- 2.0.6 2003/12/04
2230 Frontend server now transfers memory from decoded packages to stream
2233 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2234 references to show up.
2236 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2237 the ZOOM Abstract API. The older names for the same options are still
2238 also supported for the benefit of old applications.
2240 ZOOM-C supports "implementationId" and "implementationVersion" options
2241 to go along with "implementationName". These allow the user code to
2242 specify identification strings to be sent to servers.
2243 Add OID for the new ExtLite attribute set.
2245 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2246 as requested/supplid by Ere Maijala <ere@atp.fi>
2248 For generic frontend server, reverse the order of
2249 "toolkit-supplied / application-supplied" strings sent as implementationId,
2250 Name and Version. Also, remove the spaces around the slash. This brings
2251 the GFS in line with the behaviour of ZOOM-C on the client side.
2253 Add function ZOOM_scanset_display_term.
2255 yaz-client shows scan displayTerm if present.
2257 Utility yaz-iconv is now installed by default along with the man page
2260 Extend configure check for OpenSSL to use pkg-config where available (such
2263 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2264 server to specify uid/gid/mask for socket using the format
2265 unix:[user=uid,][group=gid,][umask=mask,]file=path
2266 If file= is omitted the existing format is assumed, e.g.
2268 in which case the mask is 0666 (rw for everybody).
2270 Major restructure of YAZ source. All source in libyaz is in src directory.
2271 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2272 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2274 Added man page for utility yaz-marcdump (used to be called marcdump).
2275 yaz-marcdump is installed by 'make install'.
2277 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2278 of incoming package failed.
2280 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2282 Change prototype of odr_perror: add const to message string.
2284 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2286 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2287 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2288 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2289 DNS lookup. There should not be any compatibility problems with this
2290 assuming that blocking=1 or 0 is used.
2292 Fix bad reference in UNIX comstack in function cs_addrstr.
2294 Fix for compilation on AIX.
2296 The generic front-end server (server/seshigh.c) now supports returning
2297 Init diagnostics to the client in User-information-field, in
2298 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2301 --- 2.0.4 2003/09/04
2303 Allow any CQL relation (not just all,any,exact,scr).
2305 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2306 that features the same UI.
2308 Implemented command update0 in YAZ client which is equivalent to
2309 update but uses old of Ext Update ASN.1.
2311 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2312 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2313 Previously no OID was used for this info.
2315 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2316 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2317 returns 'malformed search term' otherwise.
2319 SortResponse member resultCount now set to NULL in sort handler of
2322 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2325 Add three new utility functions for translating OIDs between various
2326 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2327 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2328 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2329 char *oid_to_dotstring(const int *oid, char *oidbuf);
2330 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2332 Reverted modifications for ES Update definition for z_IU0Update
2333 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2334 is back to YAZ 2.0.2.
2336 String value attributes for CCL parser.
2338 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2339 which their FirstSearch server returns in Init responses, sometimes
2340 carrying useful diagnostic information when Init fails. This has the
2341 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2342 "z39.50/oclcui.asn", where its definition is somewhat different from
2343 what OCLC document on their web-site, as required to interoperate with
2346 Support for anonymous authentication in yaz-client. Use the command
2349 * Fix the OID of the Index Data-local "admin" Extended Service from
2350 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2351 the 1000, which indicates a locally-defined OID, was a mistake.
2353 --- 2.0.3 2003/06/20
2355 Fix CCL directive @case handling so that it affects string match for
2356 both CCL keywords and qualifiers.
2358 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2359 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2360 Decoder has been updated with ASN.1 changes as listed in
2361 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2362 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2363 z_IUUpdate, remains unchanged.
2365 ZOOM_record_get may now return a record in a specific character set.
2366 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2367 "from" is the character set of record as returned by target. "to" is
2368 the character set to be returned. If omitted, "to" is UTF-8.
2370 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2372 New ODR utility, odr_getelement, which returns name of element for
2373 which encoding/decoding failed.
2375 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2376 in cases where a required element was omitted.
2378 Bug fix: some MARC8 sequences were not converted.
2380 New ZOOM option "step" which specifies number of records to be
2381 retrieved in one chunk. Used in conjunction with "start" and "count".
2383 SRW support for yaz-client. Use scheme http: to use it, e.g.
2386 yaz-client no longer does (un)intelligent character set conversions
2387 by default. Can be enabled with charset and marc_charset commands.
2389 xmalloc trace fix for 64-bit systems such as DEC alpha.
2391 Solaris 2.6 compile fix.
2393 New function, cql_strerror() translates SRW error codes, as returned
2394 by cql_transform_error(), into human-readable English strings. Used
2395 in yaz-client diagnostics when appropriate.
2397 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2398 converts it into a type-1 query which is sent to the server. This
2399 makes CQL available for use with all Z-servers, as opposed to the tiny
2400 minority that can handle CQL queries themselves.
2402 --- 2.0.2 2003/04/28
2404 New Debian package layout similar to the Redhat Package layout.
2406 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2407 and search result respectively.
2409 --- 2.0.1 2003/04/25
2411 Redhat package is now several packages: libyaz (runtime libraries),
2412 libyaz-devel (development and documentation, and yaz (utility programs).
2413 Package spec file by Morten Bogeskov.
2415 New member 'schema' in struct bend_fetch_rr which the name of requested
2416 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2417 handler MAY set this to reflect the schema of the returned record.
2419 New member 'display_term' in struct scan_entry. GFS now sets member entries
2420 and allocates scan entries to be filled by user scan handler. In previous
2421 version, entries member was allocated by the scan handler. That still works,
2422 but the GFS will ignore member display_term - assuming it was NOT set by
2423 the handler. The fact that the GFS now allocates the entries both allows
2424 for new members and makes a scan handler easier to write.
2426 Fix CQL lex buffer overflow.
2428 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2429 SRU default recordPacking is string.
2431 SRU protocol support for frontend server.
2433 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2435 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2437 Added scan for the ZOOM shell (zoomsh).
2441 * String Identifers for Schemas (Amendment 5).
2442 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2443 Old definition for schema
2444 Odr_oid *schema; /* OPT */
2449 Z_InternationalString *uri;
2450 #define Z_Schema_oid 1
2451 #define Z_Schema_uri 2
2454 * resultCount parameter to Sort Response (Amendment 1).
2455 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2457 Support for SRW 1.0 over HTTP. This is an optional feature and
2458 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2461 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2462 on the same port. SRW SearchRetrieveRequests are mapped
2463 to bend_init,bend_search,bend_fetch,bend_close.
2465 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2467 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2468 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2470 ZOOM connections are SRW based if schem http is used for hostname
2471 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2472 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2474 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2475 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2476 distance=n, order=true/false, relation=le, prox unit=word. If
2477 n is omitted, distance 1 is used.
2479 Fixed problem with C compiler include path in wrong order.
2481 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2482 on Solaris. Patch from Ko van der Sloot.
2484 New MARC decode API. All new functions operate on a yaz_marc_t
2485 handle. The most important new functions are: yaz_marc_create,
2486 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2487 decode and destroy respectively. Decoder can produce formats
2488 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2489 include/yaz/marcdisp.h.
2491 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2492 to UTF-8, UCS-32, wchar_t or Latin-1.
2494 * Prototypes for yaz_iconv_-functions moved to separate header
2495 include/yaz/yaz-iconv.h.
2497 Make a few private functions 'static' in unix.c. This prevents
2498 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2500 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2501 are set when Init Response is received.
2503 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2504 but returns diagnostic set as well.
2506 New function yaz_strerror which is a portable wrapper for
2507 strerror/strerror_r/GetLastMessage.
2509 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2510 is returned for MARC. If type is "oai", then OAI MARC is returned.
2512 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2515 --- 1.9.2 2002/11/26
2517 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2519 Fix bad race conditions on SIGTERM and terminate gracefully in
2522 Move retrieval (data1) module to Zebra since nobody seems to be
2525 Add GRS-1 render for ZOOM using same format as yaz-client.
2527 --- 1.9.1 2002/10/05
2529 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2531 Fix broken ESpec handling in data1 module.
2533 SGML reader parses comments and makes them part of the data1 tree.
2535 Added several type casts so that YAZ compiles as C++ code.
2537 ZOOM didn't handle PDU encoding failures properly.
2539 Added more Bib-1 diagnostics (approved extensions).
2541 GNU configure: better check for iconv.
2543 More portable use of accept, getpeername. Check for socklen_t. Use
2544 int/size_t if socklen_t is not defined.
2548 PQF parser rejects bad queries - including those with extra
2549 characters in them. PQF parser used to silently ignore that.
2550 Cleaner API for PQF added, which allows you to get detailed
2551 error information for bad queries (see yaz/pquery.h).
2553 Fixed bug in ZOOM_record_get for type "database".
2555 Implemented mini iconv library supporting conversions between
2556 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2558 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2560 --- 1.8.9 2002/08/20
2562 Fixed ZOOM C record cache so that preferredRecordSyntax and
2563 elementSetName is used to check for already fetched records.
2565 --- 1.8.8 2002/08/02
2567 Added three members in bend_initrequest structure to facilitate
2568 character set negotiation.
2570 Fixed a bug in frontend server that could cause indefinite
2571 loops under rare conditions.
2573 Revised character set utilities (charneg.h) so that encoding
2574 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2576 For PQF, directive @term <type> sets term type for Scan/Search.
2577 Here <type> is general, string, numeric, null. The term type
2578 is inherited - just like @attr.
2580 New call odr_set_charset that sets character set conversion for
2581 international-strings on a ODR stream. Prototype is:
2582 int odr_set_charset(ODR o, const char *to, const char *from);
2583 The InternationalString is still represented as C string in YAZ
2584 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2585 won't). On the protocol level, you can use any encoding.
2587 Support for UNIX sockets in ZOOM.
2589 Solaris recv sometimes returns errno == ENOENT. It is treated as
2590 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2592 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2593 both client and server. Code by Morten Bogeskov.
2595 --- 1.8.7 2002/05/22
2597 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2598 that they can be used directly from Visual Basic. You must recompile
2599 your windows APP if you're using ZOOM.
2601 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2602 Commands "lang" and "charset" sets language and character set respectively.
2603 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2604 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2606 Attributes from multiple CCL fields may be OR'ed rather than merged
2607 using directive "@field or". Fields are still merged by default -
2608 equivalent to "@field merge".
2610 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2613 Fixed bug in zget for parameter ExtendedServicesResponse.
2617 --- 1.8.6 2002/03/25
2619 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2621 Client displays USR.1:SearchResult-1 (hits per term).
2623 Additional Search Info for search in Generic Frontend Server.
2625 Fixed CCL parsing of "field=s".
2627 WIN32 installer - using the excellent NSIS software from nullsoft.
2629 Fixed CCL parsing of "field = - <number>".
2631 Added function yaz_marc_decode that decodes MARC for line mode
2632 display or XML (similar to that used by JZKit).
2634 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2635 Z39.50. But ISO/ILL was, however.
2637 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2638 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2641 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2643 --- 1.8.5 2002/02/03
2645 New YAZ client features: Command completion and new commands:
2646 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2647 Code provided by Jacob Poulsen.
2649 New call oid_trav, that visits all registered OIDs via callback.
2651 Function ZOOM_record_get now returns const char pointer rather than
2652 void pointer. It saves a lot of type casts.
2654 For YAZ client, command "auth" now allows you to set authentication
2655 in IdPass style. It is enabled when three tokens are given - order
2656 is user, group and password.
2658 Fix memory leaks in MARC record handling for ZOOM.
2660 New option for YAZ client, -k <kilobytes> that sets
2661 maximum record size. Similar to -k option for generic frontend
2662 server and yaz-ztest.
2664 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2666 Prefix query parser reports "fail" when bad attribute set is given.
2668 Fix in MARC decoder. Proximity logging. Fix for attribute set
2669 in scan handler for server. Patches by Shigeru Ishida.
2671 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2674 Configure option --with-openssl=<dir> now works when a directory is
2675 specified. Patch provided by Morten Bogeskov.
2677 New option for YAZ client, -u <auth>, that sets authentication.
2679 ZOOM fix: error information was sometimes "missing", since error
2680 was cleared/reset too when it shouldn't.
2682 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2684 --- 1.8.4 2002/01/04
2686 Scan for ZOOM API. New object ZOOM_scanset. New functions
2687 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2688 ZOOM_scanset_destroy.
2690 New ZOOM function, ZOOM_connection_last_event, that returns type
2691 of last event (such as "receive data", "send data", "apdu received",
2694 New ZOOM option, schema, that specifies schema for retrieval.
2696 New CCL feature. Qualifiers can be aliases for one or more
2697 other qualifiers (if more than one is given, OR is used).
2699 ZOOM uses named result sets if target supports it.
2701 Two new YAZ client commands: . (dot, which sources a script of YAZ
2702 client commands), and ! (to execute shell command.). Implemented
2705 Working on Debian packages.
2707 --- 1.8.3 2001/11/19
2709 YAZ client enables named result sets only if target supports it.
2711 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2713 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2714 with key="host" to get same result.
2716 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2717 Function Z3950_resultset_record(s) returns references to records
2718 "owned" by resultset. To become owner use Z3950_record_clone.
2720 Function z_ext_record handles Extended Services. Thanks to
2723 --- 1.8.2 2001/11/12
2725 CCL Parser fix: ignore token comma when dealing with and-lists.
2727 Documentation updates for COMSTACK.
2729 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2730 Changed prototype Z3950_records. For some functions, int parameters
2731 were changed to size_t.
2733 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2736 New MARC decode/display function, marc_display_exl, which properly rejects
2737 non-ISO2709 records. YAZ client uses it.
2739 --- 1.8.1 2001/10/29
2741 Fix bug: local attribute set wasn't set correctly in PQF strings.
2745 * Old Z39.50 codecs no longer supported.
2747 Added ZOOM C binding. See http://zoom.z3950.org/
2749 Renamed states for COMSTACKs to avoid confusion with events.
2751 Implemented cs_look and proper cs_rcvconnect.
2753 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2755 Configure detects POSIX threads on OpenBSD.
2757 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2758 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2760 When error is returned from present handler, non-surrogate diagnostic
2761 is returned in present response (and fetch handler is no longer called).
2763 * Minor adjustments to pquery parser (PQF). Token characters may be
2764 escaped by using backslash (C-style).
2766 PQF parser allows string attribute values to be specified. For @attr,
2767 non-numeric characters after the equal-sign are treated as strings
2768 (e.g. @attr 9=title).
2770 CCL trunction character may be defined (@truncation in file)
2772 * function zget_ExtendedServicesRequest sets waitAction to
2773 waitIfPossible (was wait).
2775 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2778 CCL operator names may be set in field definition files (CCL_bibset).
2779 See ccl/bib1 for an example.
2781 Fixes in ASN.1 compiler for C++ compatibility.
2783 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2784 and "op_or" to avoid conflict with C++.
2786 Fixed problem with GNU readline detection on Redhat 7.0.
2788 Added step-size for Scan backend handler.
2790 Fixed bug that made the frontend server crash when no attribute
2791 set was specified for scan.
2793 Front-end server automatically switches to original working directory
2794 when installed as an NT service. Previously -w had to be specified to
2797 Added extended attributes for retrieval module (data1), so that data1
2798 records carry d1_readXML/SGML attributes. d1_read also supports
2799 null-data rules ( <tag/>)
2801 On UNIX when POSIX threads are available, a separate library libyazthread
2802 is created. Programmers should link with that library and the yaz library
2803 when using threads. The reason for the split was that some applications
2804 on Linux, such as Apache, doesn't work well when using shared objects that
2807 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2808 (or any frontend server) in SSL mode by specifying ssl: followed by
2809 address. Only tested on UNIX.
2811 Added feature for CCL module. Virtual structure s=al or s=ol generates
2812 and-list and or-list respectively instead of phrase search.
2816 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2817 log_mask_str. This was done to avoid name conflicts with other libraries
2818 (such as other PHP extensions).
2820 Added raw OID member for preferred record syntax (request_format_raw)
2821 and returned record syntax (output_format_raw) for backend fetch method.
2823 Config file yaz-config now accepts options so that it returns specific
2824 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2826 Shared library support for UNIX using GNU libtool.
2828 * Modified backend interface. Request/Response struct's replaced by
2829 one read/write C struct. For example bend_fetchrequest and
2830 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2831 Every handler - even search has to be registered in bend_init
2832 handler. This means that the YAZ library no longer refers to
2833 external functions and it makes it possible to make the whole
2834 thing a single DLL/SO.
2836 Added Segment handler for backend server.
2838 Added Zmbol/Zebra administrative functions to YAZ client.
2840 Threaded frontend server on UNIX (when POSIX Threads are available).
2841 Starting the server with option -T enables multi-threading.
2845 Added configure option --enable-comp/disable-comp to control use
2846 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2847 located in sub directory asn.
2849 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2850 in ${exec_prefix}/bin along with the other programs yaz-client and
2853 GNU automake used to maintain makefiles.
2855 Added several OID's.
2857 Changed retrieval module so that we can load records with no abstract
2858 syntax defined. Tagpaths in these records are fully composed of string
2861 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2865 On UNIX, the generated makefile now supports a proper 'make install'.
2866 The prefix can be set via GNU configure to set the install location
2867 (default is /usr/local).
2869 * YAZ programs client and ztest were renamed to yaz-client and
2870 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2871 locations, such as /usr/bin,/usr/local/bin,etc.
2873 * YAZ Header files were moved from include to include/yaz. YAZ Header
2874 files are referred to as include <yaz/log.h> rather than <log.h>.
2875 The YAZ include path (-I ..) is therefore the same as before. Programmers
2876 should update their #include statements or use -Ipath/include/yaz
2877 instead. The main motivation for doing this change is that YAZ header files
2878 can be installed in "standard" locations /usr/include,/usr/local/include
2879 without introducing conflicts, since ALL YAZ header files are stored
2880 in subdirectory yaz (under /usr/include for example).
2882 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2883 rather than project/workspace files. We switched because project files
2884 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2887 Changed name of logging function, logf, to yaz_log, to prevent name
2888 clash with some math-log functions. The YAZ header log.h defines logf
2889 to yaz_log (#define) so there should be no incompatibilities by this
2892 Added bend_start/bend_stop handlers for server. These handler are
2893 called on start/stop of server. For windows they are called whenever
2894 a service is started/stopped.
2896 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2897 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2898 in util/yc.tcl. The auto-generated C code structures are, in a few
2899 cases, incompatible with the old decoders. There are differences in the
2900 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2901 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2902 The preprocessor variable ASN_COMPILED is defined when the compiled
2903 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2904 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2905 wish to use the old encoders/decoders you can specify --disable-yc
2908 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2909 version so that it supports both new - and old version of DB Update
2911 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2912 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2913 change. The name parameter can be set to 0 in which no name is specified
2914 for the construction. The macros odr_implicit and odr_explicit sets name
2915 parameter to zero for the construction involved. New macros
2916 odr_implicit_tag and odr_explicit_tag are similar to the others,
2917 except that a name parameter is added. For programmers' that don't use
2918 ODR they probably only need to change the call to z_APDU and z_External.
2920 Added access control facility by interfacing the TCP wrapper library.
2921 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2922 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2923 name of the daemon and enables the access control as specified in
2924 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2926 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2927 den Dool <H.M.vdnDool@kub.nl>.
2929 Added reference ID parameter to most functions in server API - refer
2930 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2932 Changed name of ccl library to libccl.a (was ccl.a).
2934 Fixed bug in decoder for Explain (Category TargetInfo).
2936 Added support for GNU readline in client. Thanks to Jacob Poulsen
2937 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2939 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2940 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2941 IMPLEMENTATION! This change was made to the development version before
2942 the ZIG decided to retract the amendment. If any users MUST be
2943 compatible with the original Update definition, PLEASE CONTACT US, and
2944 we will include a separate definition corresponding to the old Update
2945 ES. Note that because of the change to the ASN.1 of the
2946 TaskPackageRecordStructure we cannot define a single structure that
2947 will support both versions.
2949 * Added const modifier to buffer parameter for some ODR/BER encoding
2950 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2951 completeWAIS, odr_dumpBER.
2953 Fixed bug in client.c which caused a crash when a scanResponse didn't
2954 contain positionOfTerm.
2956 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2957 * will cause an error in a client if a non-YAZ target sends both a
2958 * list of Scan entries and non-surrogate diagnostics.
2960 Retrieval module enhancements. Tag sets may be typed in the reference
2961 to it. From the .abs-file the "tagset" directive takes a third optional
2962 integer type for the tag set referenced. From a .tag-file the "include"
2963 directive takes a third optional type as well. The old "type" directive
2964 in the tag set itself is still recognized but acts as the default type
2967 Backend interface change. Individual Scan terms returned from bend_scan
2968 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2969 in include/backend.h.
2971 Retrieval module enhancements. Multiple tag sets and attribute sets may
2972 be specified in abstract syntax specs. Revised the error/warning for
2973 logging messages reported by the retrieval module when reading the
2976 Object Identifier system (oid_..) changed. The API is backwards
2977 compatible but the oid-routines now allocates new OID's when needed.
2978 Raw OID's may be specified in oid_getvalbyname.
2980 YAZ now uses GNU configure to generate Makefile(s).
2982 * Minor changes in some of the member names of DeleteResultSetRequest and
2983 DeleteResultSetResponse. See include/proto.h.
2985 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2986 and added member 'languages' in TargetInfo (which was missing).
2988 Changed the way attribute sets are handled in the retrieval
2989 module. These are now cached, just like the abstract syntaxes
2992 Changed YAZ so that it links with compiled ASN.1.
2994 Added Explain-schema definitions and mapping routines. The following
2995 Explain categories have been implemented: AttributeDetails,
2996 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2998 Fixed minor bug in Windows version of Server Library.
3000 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3002 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3004 Added EXTERNAL: UNIverse Resource Report (non-standard).
3006 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3007 ENUMERATED and SET OF.
3009 * Added 'const' to some of the char pointer arguments for the
3010 functions, data1_read_node, data1_getelementbytagname,
3011 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3014 Fixed bug in data1_insert_taggeddata - the last_child member of
3015 parent wasn't initialised.
3017 * Changed data1_read_record and data1_read_node so that the supplied
3018 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3019 doesn't refer to any parts of the "SGML"-buffer.
3021 Fixed bug in server library (Windows version of statserv_remove).
3023 * Changed code so that it compiles as C++. The type definition
3024 of Odr_fun which is a member of Odr_arm was changed. The result is,
3025 that an explicit typecast is needed for the fun pointer when
3026 using Odr_arm - as in:
3027 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3029 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3031 Implemented the new structured date and time definition as approved
3032 by the ZIG. Added schemaId element to the specificTag in Espec-1
3033 (also approved at the last ZIG). Thanks to RVDM.
3035 Added some Object identifiers (RVDM).
3037 Changed the Update Extended Service (RVDM).
3039 Added command "refid" to client which specifies referenceId for
3040 the following requests.
3042 Implemented extended service handling for server. See ztest.c
3043 for an example as well as backend.h. New handlers are registerd
3044 in the Init handler.
3046 * Changed interface for sort in server.
3048 Added new members to statserv_options_block. It allows a server
3049 to read options from another source than just the command line. Thanks
3050 to Charles Woodfield.
3052 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3053 renamed to zboolean. Some C++ compilers complained about the name.
3055 Minor changes to gils.abs. Added index 's' (sort) on title
3056 and date/time-last-modified.
3058 --- 1.4pl2 1998/1/30
3060 Fixed bug in server library regarding inetd mode (-i). This bug
3061 was introduced by release 1.4.
3063 --- 1.4pl1 1998/1/29
3065 Added sort facility in client and backend server interface.
3067 Fixed problem with dependencies in Makefile(s).
3069 Fixed bugs for encoders/decoders of extended services and
3072 Implemented sub-tree feature for schemas. Sub-trees are
3073 referenced in *.abs-files. See explain.abs for an example
3074 of the use of this feature.
3076 Modified bib1.att; local attributes for ANY didn't include
3077 ANY itself (only affects use of the retrieval module).
3079 Fixed bug in plain SGML reader in function data1_read_node:
3080 tags with prefix "var" was incorrectly interpreted as variants.
3082 Added feature "sub-schemas" to enable references to - and definitions
3083 of - group of elements.
3085 * Removed member parent from type data1_element (in data1.h).
3087 Implemented function odr_nullval() that returns the value of
3090 * Removed member num_children from data1_node (in data1.h).
3092 Made NT service interface part of the server library. The
3093 function statserv_main uses the NT service when required and
3094 calls the statserv_start / statserv_close routines.
3096 Routine zget_SearchRequest and zget_PresentRequest fills
3097 resultSetName/Id member with "default" instead of "Default".
3099 Fixed memory leak in server. Request queue member wasn't freed.
3101 Fixed nmem_exit so that memory is freed.
3105 Revised the CCL parser utility to be thread safe.
3107 Added function, oid_ent_to_oid, to replace the function
3108 oid_getoidbyent, which is not thread safe.
3110 * Added nmem_init and nmem_exit to initialize and release
3111 NMEM resources. Function nmem_init should be called once in the
3112 initial thread before NMEM/ODR is used. statserv.c and client.c
3113 have been changed accordingly. The change was necessary to make
3114 NMEM thread safe. The NMEM memory pool is shared amongst threads
3115 in a process. Unix-based applications will still work fine without
3118 Added NT Services interface for the the Z39.50 (statserv) Server.
3119 Refer to the ztest.c source on the usage.
3121 Windows 95/NT port using MSVC5.0. Project files are included in the
3124 * Defined new 'global' handle for the retrieval (data1) system. The
3125 new handled, data1_handle, describes the state of the data1 system.
3126 This handle is passed as first argument to virtually all
3127 data1 related routines. The functions data1_create and data1_destroy
3128 creates and destroys a data1 handle respectively.
3130 Added ODR encode stream member to all backend request structures
3131 init, search, scan etc. This stream should be used to allocate all
3132 memory used for the response when thread safe operation is needed.
3134 Changed the comstack utility, cs_addstr, to be thread safe. The
3135 returned hostname string returned by the function is now part the
3138 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3139 function. The cs_straddr takes a COMSTACK handle as argument, so this
3140 function must be used after cs_create and before bind/connect.
3141 This function is thread safe.
3143 Moved test server to 'ztest' directory - generic server code still
3144 in 'server' directory.
3146 Made prefix query (pquery.c) utility thread safe.
3148 Added new function modifier YAZ_EXPORT to 'export' public DLL
3149 functions when using windows (see include/yconfig.h).
3151 Added definitions to the OID database (util/oid.c) (RVDM).
3153 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3155 Added call to ccl_rpn_delete in client program.
3157 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3158 release of RPN structure.
3160 Added support for C++, headers uses extern "C" for public definitions.
3161 With input from RVDM.
3163 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3164 Thanks to Ronald van der Meer (RVDM).
3166 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3168 Added support for private extensions to the OID database
3169 (oid_setprivateoids()). Thanks to RVDM.
3171 Added optional, physical ANY (key replication)
3173 Fixed null-reference problem in GRS-1 output filter.
3175 Proximity operator added to Prefix Query Format (PQF).
3177 In test client command "base" accepts multiple databases.
3179 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3183 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3185 Smallish bug-fixes in the new encoders/decoders (explain).
3187 Bug fixed in DeleteRequest.
3189 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3191 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3193 Added SOIF syntax (using private OID for now) to retrieval module and client.
3195 Added Update extended service.
3197 Added SearchResult-1 additional info structure.
3199 Added optional CCL (ISO8777) interpreter as separate module. Available
3202 --- 1.2 1996/6/10 (1st anniversary release)
3204 Added Summary record syntax. Lightly tested.
3206 Added OPAC record syntax. Untested.
3208 Added ResourceReport service encoders/decoders. Untested.
3210 Fixed bug in z_Unit - wrong tagging on unitSystem.
3212 Fixed bug in the DiagRecs decoder.
3214 Added options for max PDU size and session timeout to frontend-server.
3216 Added documentation of query-language parsers and other supporting utilities.
3218 [frontend-server] Added Attribute set to the bend_scanrequest API.
3220 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3221 surrogate diagnostics were generated.
3223 [retrieval] Allow multiple local values for attribute.
3225 [retrieval] Allow multiple attributes per element in .abs files. index type.
3227 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3229 --- 1.1pl2 1996/4/10
3231 Minor changes, mostly specific to Zebra's requirements (retrieval)
3235 Repaired bug in frontend server when running multiple listening
3236 endpoints in dynamic mode.
3238 z_External() now won't break if a known, ASN.1 value comes encapsulated
3239 in an octet-string. The value will pass through unmodified in an Odr_oct.
3241 Added a bit of code to the demo client to decode & display
3242 ASN.1-structured records represented in the octet-aligned branch of
3243 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3245 Added z_ext_getentbyref() to the ASN module. Doc updated.
3247 * Completed the SCAN definition in the ASN module. This may break SCAN
3248 code based on older YAZ-versions at compile-time. The fix is easy -
3251 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3252 under the SCAN definition. Remember to initialize this, server-people.
3254 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3255 that this does not extend to ODR and ASN.
3257 Comstack allows insertion of established socket (primarily for
3258 inetd-operation of servers). Doc updated.
3260 Front-end server can now start from the inetd in TCP mode. Doc
3263 --- 1.0pl4 1996/1/24
3267 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3268 the rank and record number.
3270 Adjustments to the frontend server.
3272 Fixed diagnostic BER dumper. It ignored the file argument.
3276 Various changes to retrieval module.
3278 Changed the union discriminators of the protocol files from enums to
3279 ints paired with #defines.
3281 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3284 *Changed operator in the RPN structure to 'roperator', again to avoid a
3287 Fixed problems in Explain decoders/encoders.
3289 --- 1.0pl2 1995/12/6
3291 Memory bug in log module fixed.
3293 --- 1.0pl1 1995/12/5
3295 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3297 Bug in Explain DatabaseInfo module fixed.
3299 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3303 The shift to v1.0 signals that we now consider the *core* functionality
3304 of YAZ reasonably stable (the core being more or less equivalent to
3305 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3306 tested (Explain not at all - though that will happen soonish).
3308 Minor changes to code to support Windows port.
3310 Various minor changes after we're getting to use GRS-1 & co. more.
3312 Added Espec-1 format.
3314 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3315 of the protocol and it cannot be selected when encoding (maps into 'string'
3316 when decoding). Needed to talk to some servers.
3318 Demo client can request simple element set names.
3320 Added Diagnostic Format encoders/decoders.
3322 Added simple Close handling to frontend server (no hooks for resource
3323 reporting yet), and demonstration client.
3325 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3327 --- 1.0b3 1995/08/24
3329 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3330 handled incorrectly when records were requested in the searchResponse. This
3331 will only affect you if you use the frontend-server.
3333 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3334 Test-client will ask for and print GRS1. Ztest will return dummy records
3337 Added Explain encoders/decoders to the service-level API. Untested.
3339 Added Extended Services: Item Order encoders and decoders to the Service-
3340 level API. Untested. We could use a recent copy of the pertinent bits
3341 of the ILL protocol to add those bits.
3343 Added diagnostic format 1 encoders/decoders to the service-level API.
3346 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3347 odr_cons.c, which causes a more correct output.
3349 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3350 was always set to 0 when no records were requested in the searchRequest.
3352 * Added better external-handling. This shouldn't harm old code that
3353 *encodes* externals. It can break code that looks for a
3354 'single-ASN1-type' representation, since those types that are known
3355 are now decoded immediately. Look at the SUTRS sample code in
3356 seshigh.c and client.c. Documentation updated.
3358 Handling of structured records in bend_fetchresponse. Length -1 marks
3359 structured record, type is deduced from format field.
3361 --- 1.0b2 1995/06/27
3362 Fairly quick maintenance release to add SUTRS support.
3364 Fixed handling of SUTRS records in the demonstration client.
3366 * Added format field to the bend_fetchrequest and bend_fetchresponce
3367 structures of the backend API (frontend server). When the record is
3368 returned, the value of the format field is mapped to an OID. The
3369 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3370 of the record. The special value VAL_NONE in the bend_request means
3371 that no specific format was requested by the client. Documentation
3372 updated accordingly. Test server (ztest) will return a fixed dummy
3373 SUTRS record if your client requests SUTRS.
3375 Documentation updated accordingly.
3377 You can now set external libraries and RANLIB support in the top-level
3381 First public release.
