3 New GFS search member: present_number. This is a hint to the
4 search handler how many records are going to be fetched immediately
5 following search. There's no guarantee that it's going to be the case,
6 since it depends on hit count (for Z39.50 piggyback) and whether errors
9 Make a few functions static (private). The functions getbyte_stream,
10 ungetbyte_stream and yaz_gets are now private. They were never declared
13 yaz-marcdump: exit(5) for serious decoding errors
15 ISO2709 decoding: be more picky WRT header
17 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
18 was only used as to indicate that next-result-set-position should be
20 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
21 Based on patch from Ashley Sanders.
23 Make some functions static/private in PQF parsing. Those functions were
24 never declared in a public header and so should not be in use by
25 applications based on YAZ.
29 ZOOM: special options to control APDU logging.
30 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
31 logging of APDUs until "saveAPDU" option is set again. If logging is
32 already enabled the effect is that current APDU buffer is cleared.
33 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
34 logging (default behavior on new connection).
35 The APDUs sent/received can be obtained by using
36 Using ZOOM_connection_option_get(c, "APDU") or
37 ZOOM_connection_option_getl(c, "APDU", &l).
39 GFS: relay implementation_version from backend
40 From 3.0.40 and later, implementation_version from backend was
41 not used in init response at all.
45 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
46 mode at all. Probably never did.
48 Make a new version of ztest.pem that, at least, is not expired.
52 Fix description of CCL directive 'case'.
54 More tight checking of form arguments (yaz_uri_to_array). Makes
55 YAZ better at rejecting big and/or bad POSTs.
57 SRU decoding does not report more than up to 10 invalid arguments.
59 rpn2cql: less quotes in generated terms. Semantics unchanged, but
60 it's prettier this way.
64 New utility yaz_decode_init_diag. Defined in proto.h.
66 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
67 given for unix local socket.
68 The COMSTACK string for doing so is:
71 unix:/myfile:tcp:localhost:9999/mybase
72 unix:/myfile:localhost:9999/mybase
73 unix:/myfile:http://fakehost/mybase
75 debian: Use dpkg-buildflags in build process.
79 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
80 global's SRU service uses a recordPosition scheme starting from zero.
81 First record's position should be one
82 according to the standard.
86 Allow more namespaces for SRU. This is to allow, for example, an
87 incorrect namespace returned from server
88 http://services.igi-global.com/sru .
90 Minor fixes for compilation on Windows.
94 daemon: log total number of bad signals from child on stop so that it
95 is more easy to spot problems with child worker processes.
97 retrieval: empty backend name attribute omits element set
98 from being used in retrieval.
100 --- 4.2.40 2012/10/04
102 Implement Solr sort strategy "solr", similar to sru11 sorting.
103 This will implement the correct parameters on Solr requst to do
106 --- 4.2.39 2012/09/28
108 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
111 MARC: Extra/missing indicator handled for MARCXML.
112 The indicator length is given in header and is the same for the
113 whole record. If attributes ind1, ind2 are missing, then content
114 character defaults to blank. Extra indicator attributes (beyond)
115 indicator length are treated as an error.
117 Reformat: delete trailing whitespace
119 --- 4.2.38 2012/09/17
121 MARC: fix non-ASCII characters for leader. This is to ensure we can
122 generate XML in UTF-8.
124 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
125 in one node with structure word.
127 --- 4.2.37 2012/09/04
129 yaz-json-parse: JSON output may be pretty printed by using option
132 Increase default value of max message for Z39.50 Init for GFS, ZOOM
133 and yaz-client. Old value was 1 MB. New value is 64 MB.
135 --- 4.2.36 2012/08/22
137 yaz-client: don't display bogus records from SRU servers. Some SRU servers
138 return more records than given by *maximumRecords*. Skipping those in
141 record_render: simplify buffer return handling and fix at least one bad
142 memory reference, that broke the test_embed_record sometimes.
144 Allow http://user:pass@host notation for yaz_url_exec.
146 zoomsh: allow shell command to be executed. Via the system(3) call.
148 yaz_poll: Allow num_fds == 0
150 yaz-client: fix bad encoding of "itemorder item". The itemorder
151 item <no> - command forgot to use length of encoded Item Request
152 package. Error present since YAZ 3.
154 yaz-ztest: fix bad usage of session handle. Bug was introduced when
155 result sets were saved (271a9c83).
157 SRU recordPacking: guess record packing in response rather than looking
158 at the recordPacking element which, OF COURSE, changed semantics in SRU
161 Decode SRU 2.0 responses. The official namespace for responses, according
162 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
163 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
164 nature.com's server, however, usee namespace
165 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
166 we are now using a glob-expr to match up the namespace. ZOOM C and
167 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
168 I can not find a single real example showing the "real" namespace in
169 the documentation from OASIS. The namespace for requests is different
170 from responses, but this is not added to YAZ yet, when we don't encode
173 --- 4.2.35 2012/06/26
175 zoom/record_render: add support for Base64 decoding fo MARC records
176 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
177 which will decode base64 + ISO2709 marc-8 encoded material from text node
180 --- 4.2.34 2012/06/07
182 Add missing definitions ZOOM_resultset_get_facet_field_by_index
183 and ZOOM_resultset_facets_names.
185 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
188 Change APDU dump printing to avoid long leading blanks. For levels 16
189 or larger the level is shown and the indentation is truncated but
190 recursed with modula 8. This makes it still reasonable easy to read
191 - even for nested BER dumps.
193 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
194 return 0 (incomplete package) in case where the BER package was
195 considered too nested (return value of -2).
197 dumpber: lines of level 15 are not indented further. Two spaces per
198 indentation; indentation 15 or more is indented to a fixed indentation
199 and augmented with a level=<no> indication.
201 zoomsh: increase max size of command+args
203 GFS: No limit in RPN buf size in CQL to RPN conversion.
205 --- 4.2.33 2012/05/09
207 New function for daemon utility, yaz_daemon_stop .
209 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
211 --- 4.2.32 2012/04/25
213 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
214 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
216 --- 4.2.31 2012/04/23
218 YAZ daemon utility relays SIGUSR1 to child process.
220 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
221 would result in en empty database list - which in turn would result in
222 encoding failure for search.
224 Fix reading beyond string in yaz_sort_spec.
226 --- 4.2.30 2012/04/11
228 Add two new SRU diagnostics:
229 236: Access to specified database denied
230 1015: Init/AC: Maximum number of simultaneous sessions for Userid
232 Document the very useful ZOOM-C option "apdulog".
234 CQL to RPN: term may be passed through verbatim. This is enabled with
235 truncation.cql . The assumption being that the term is already CQL.
237 --- 4.2.29 2012/03/20
239 record_conv: leader spec may be given for marc element.
240 The leader spec is given as attribute leaderspec for element marc.
241 For example to convert a MARC21 record from MARC-8 to UTF-8:
242 <marc inputformat="marc" outputformat="marc"
243 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
245 record_conv: allow user-XSLT params. For example:
246 <xslt stylesheet="MARC21slim2DC.xsl">
247 <param name="myparameter" value="myvalue"/>
248 <param name="otherparameter" value="othervalue"/>
251 record_conv: fix error handling for missing marc charsets.
253 CQL: fix extra terms in wrong order.
255 --- 4.2.28 2012/03/06
257 record_conv: modify new API for conversion types. The conversion types
258 may be passed in new functions yaz_record_conv_configure_t and
259 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
261 Avoid mixed statement/variable declare; fixes compilation with Visual
264 --- 4.2.27 2012/02/28
266 Add non-standard SRU diagnostic: 235: "Database does not exist".
267 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
268 Update SRU to Bib-1 diagnostic maps accordingly.
270 CCL: add two new diagnostics for unsupported masking. The new
271 diagnostics are: "Embedded truncation not supported" and
272 "Single charcacter mask not supported".
274 --- 4.2.26 2012/02/23
276 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
278 --- 4.2.25 2012/01/11
280 Build YAZ for Ubuntu Oneiric.
282 CCL: allow parantheses for proximity operands. For example CCL query
283 (a) % (b) is now allowed.
285 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
286 marked dead, rather then being destroyed. If not, the session memory is
287 being free'd before the search/scan handler is finished. Also destroy
288 'request' memory in request_release rather than in various places,
289 which resulted in leaks from time to time.
291 --- 4.2.24 2011/12/21
293 cql_sortby_to_sortkeys: honor sort prefix.
295 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
296 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
297 The rpn2cql family of functions now always returns quoted CQL terms.
299 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
301 --- 4.2.23 2011/12/15
303 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
304 sequence is treated as one. For example, &&a=b&&&c& is identical to
307 --- 4.2.22 2011/12/05
309 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
310 APDUs for a connection to a WRBUF.
312 --- 4.2.21 2011/11/23
314 Fix cql_sortby_to_sortkeys. Completely broken before.
316 Make CCL's @truncation work again.
318 --- 4.2.20 2011/11/09
320 New ZOOM connection setting: tproxy. It's like proxy, but does not
321 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
322 to set resolved address + port for a connection outside ZOOM itself.
324 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
326 --- 4.2.19 2011/11/07
328 Fix uninitialized variable in Solr spell support (could cause SEGV
329 for SRU response decoding).
331 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
332 back-end's addinfo through into the ZOOM response addinfo.
334 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
335 they are separated by a colon and a space rather than simply
338 --- 4.2.18 2011/10/28
340 Add support for Solr spell-checking/suggestions through ZOOM.
341 If a Solr target has been configured correctly for spelling-checking
342 and suggestions, these will now be returned on the ResultSet option
343 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
345 --- 4.2.17 2011/09/28
347 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
348 with a flag whether to substitute escape sequences or not.
350 --- 4.2.16 2011/09/22
352 Fix nmem_strsplit_escape to substitute escape char properly.
354 New option for zoomsh -e , which makes it abort on first error and
355 return process exit code to indicate success/failure.
357 YAZ options utility supports special option -- which makes all it treat
358 all following arguments as non-options.
360 --- 4.2.15 2011/09/16
362 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
363 searched if absolute filename is given.
365 Fix conv_xslt() error-reporting when stylesheet is not found.
366 (The value of fullpath is meaningless in this situation.)
368 --- 4.2.14 2011/09/07
370 Fix problem in CQL sort node creation: un-initialized memory.
372 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
373 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
374 CQL sortby depending on whether Type-1 or CQL is actually sent to the
377 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
378 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
380 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
381 will make it possible to use both single-character mask (#) and wildcard (?)
382 in CCL . Throw diagnostic for left truncation because that is not supported
385 --- 4.2.13 2011/09/01
387 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
388 cases using escapes (\-sequences) and masking.
390 PQF parse fix: A trailing backslash followed by end-of-string (\0)
391 would result in a read one byte beyond string.
393 rpn2ccl may use Z39.50 masking for terms (t=z).
395 ICU check fix. Don't include library -lCrun on Solaris, unless present.
397 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
398 not --cppflags (which seeems like an error in icu-config).
400 --- 4.2.12 2011/08/27 RPM package only
402 cql2ccl: fix conversion of terms: operator characters were not
405 --- 4.2.11 2011/08/25 RPM package only
407 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
408 CCL parser will map both # and ? to their regular expression
409 quivalents (. and .*).
411 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
412 of reserved CQL characters.
414 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
415 is, so that they are passed through.
417 --- 4.2.10 2011/08/24
419 ZOOM SRU mode: more aggressive re-connect.
421 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
422 made available as a utility function, declared in <yaz/logrpn.h>
424 rpn2cql_structure() supports proximity nodes (except that the Type-1
425 proximity node's "exclusion" binary is ignored, as there is no way to
426 express that in CQL). Fixes bug #4564.
430 Fix SEGV that could occur if set command of zoomsh was given without
431 value (2nd argument).
433 Fix SEGV that could occur if unsupported transport was given for
434 COMSTACK - say https (when SSL was unavailable).
436 Build yaz-url on Windows too.
440 New utility to get web content. Header is url.h. A command line tool
441 yaz-url is part of the distribution and packages.
443 Fixes for SSL COMSTACK (when gnutls is in use).
445 New functions yaz_base64{encode,decode}. Header is base64.h.
449 ZOOM C includes HTTP response buffer as additional info if it fails
450 to decode the SRU response.
452 Make wrbuf_json_puts available.
456 zoom: throw diagnostic for invalid value for option "sru". Before a
457 bad SRU request was sent.
459 Adding new utility wrbuf_vp_puts.
461 Add cclxmlconfig.obj to win/makefile. It was missing completely.
465 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
466 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
467 redirect was used at the same time.
469 MARC line mode decoding: be less picky about length given - first
470 5 digits of header that is.
472 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
474 Changes to decoding of SRU records: a record with recordPacking=xml is
475 modified with a new root element <yaz_record> if the recordData contains
476 multiple children elements. This is to make the record XML parseable
479 RPN to SOLR conversion: encode special characters.
481 Generic Frontend Server: fix uinitialized member, stepSize.
485 Fix a bug in SRU decoding of records.. The database records stored
486 had un-initialized memory, but it would only be seen with yaz_record_render
487 and type_spec="ext" .
489 Fix a bug in ccl_qual_dup introduced in 4.2.3.
493 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
497 Add new utilities to convert from CQL to CCL . These utilities have
498 prefix cql_to_ccl defined in cql.h.
500 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
501 lead to memory heap corruptions when ICU utilities were in use.
505 Make compilation work without Libxml2.
507 yaz-client: remove redundant blanks in display of searchResult-1 term
512 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
513 resulting CQL node (tree) in a new node CQL_NODE_SORT.
515 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
516 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
517 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
518 Note that the CQL sortby spec is only converted when the GFS is already
519 converting from CQL to RPN (cql2rpn element).
521 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
522 specify whether to collapse delimitors or not. The existing nmem_strsplit
523 do collapse (collapse parameter = 1).
525 Windows installer: For NSIS, set InstallDir depending on x86/x64.
527 Rename internal func yaz_use_attribute_create. While non-static, this
528 function is not declared in a public header.
532 Add -lCrun when linking with ICU on Solaris.
534 More quicks character set conversions for OPAC records.
538 fix problem with record_render: records were converted (character set
539 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
543 SRU: add methods for handling DADS SRU-proxy facets.
545 Separate OPAC record character set for ZOOM_record. yaz_record_render
546 allows a character set given as charset=from/opacfrom,to where 'from' is
547 the character set of a bibliographic record, 'opacfrom' is character set
548 of OPAC record and 'to' is the target character set.
552 yaz-client: show may XML format records. Command show followed by 'format'
553 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
556 src/stemmer.c: Avoid using unnamed union. It is not supported by some
559 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
562 Update yaz.spec to operate on both SLES11 / Centos 5.5.
564 RPM: Release includes 'indexdata' name. Use indexdata in release name so
565 this package can be distinguished from other vendors.
567 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
568 as determined by configure
570 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
572 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
573 returns no error and no record, the present request is considered
574 partial (only a subset of the records could be returned by backend), and
575 so it is appropriate to set Present Status to partial-4.
579 Move yaz-config man pages to section 1.
581 More documentation about SOLR.
583 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
584 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
585 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
586 peers on some Linux systems. However, in general that does not work
587 so YAZ can not rely on that to work. Debian changed behavior in this
588 respect from Debian lenny to Debian squeeze (still testing as of Oct
590 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
592 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
596 Fix yaz-config output: echo_source not set correctly by configure.
600 SOLR WebService support for yaz-client and ZOOM.
602 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
604 --- 4.0.12 2010/08/17
606 Z39.50 facet support. Facet specifications are passed for search in
607 other-information with ASN.1 as defined in facet.asn and OID
608 .10.1000.81.5 . Facets are expressed as an Attribute list as known
609 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
610 3 is limit (number of entries to get in response). yaz-ztest returns
611 dummy facets if a client asks for them.
613 --- 4.0.11 2010/07/09
615 CCL fixes: bug 2895 and bug 3539.
617 GR1-display: add comma in display - was removed by mistake in
620 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
622 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
624 --- 4.0.10 2010/06/18
626 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
627 result set from a connection. The result set will be on its own
628 thereafter; no operations on it will perform retrievals from a target.
629 Only cached copies are returned.
631 ZOOM C:fix case for HTTP servers responding with Connection:close.
632 Ensure that if there is a current task it is resumed (like fetching
633 more records in a result set) . Bug #3484.
635 PQF parser: use odr_atoi for Odr_int (not atoi)
637 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
638 values that contain any non-digits are treated as string attributes
639 (previously decoding only checked for leading character ([0-9]). PQF
640 encoding: attribute string values are not surrounded by double-quotes.
644 New utility for managing threads - thread_create.h.
646 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
647 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
648 but YAZ' implementation do.
650 Fixes for yaz_cond-functions on Windows 7.
652 DLL export more symbols.
654 zoomsh: show record do NOT render opac.
656 Remove *.la files from Debian and RPM packages.
660 Debian package libyaz-dev depends on libgnutls-dev again (was
661 removed in YAZ 4.0.6, but due to Libtool it is still needed
662 even though yaz-config do not list libgnutls libs).
664 ZOOM: Use only one WRBUF for returning string results for
665 ZOOM_resultset. Reduces memory usage for ZOOM in general.
667 ZOOM: ZOOM_connection do not use a shared pointer to
668 ZOOM_resultset after ZOOM_resultset is destructed by
669 user. Reverts to YAZ 4.0.4 behavior.
673 record-conv: fix problem with at least one XSL conversion -
674 due to probably incorrect usage of XML XSL documents.
678 Fix yaz-config for static mode and the use of SSL (gnutls).
682 Forward decl timeval struct in mutex.h and gettimeofday.h.
684 yaz-config: fix 'static' mode linking.
688 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
689 are wrappers for pthreads or Windows. For Windows these are put in
690 a separate DLL: yaz_cond4.
692 libyaz.la (whole source) is compiled with thread. If thread support
693 is enabled enabled, all source of YAZ is compiled with treading support.
694 This allows core utilities such as yaz_log to use thread facilities.
695 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
696 thread utilities. This commit moves mutex utilities (mutex.c) from
697 libyaz_server.la to libyaz.la.
699 yaz-json-parse displays leading text until error.
703 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
704 patch from Giannis Kosmas.
706 SRU: no longer URL encode SRU database. The URL for an SRU server is
707 a URL and such is alreeady encoded - at least when given with leading
708 http:// or https://. This reverts behavior to YAZ 3.0.50.
710 Support for new MARC XML notation TurboMARC which like MARCXML is a
711 complete representation of MARC/ISO2709.. This one, however, is more
712 compact and allows for faster processing with XSLT. TurboMARC can be
713 used in the marcdisp.h API, from the yaz-marcdump utility and from
716 yaz-ztest can be configured - via the database - to perform certain
717 delays when it performs operations search, present and single record
718 fetch. This allows testers to make yaz-ztest act as a real or even slow
719 Z39.50 server. Refer to the yaz-ztest man pages for details.
723 wrbuf_destroy allows NULL WRBUF passed to it.
725 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
727 Add ZOOM_connection_close.
729 No fixed size buffers for ZOOM shell - bug #3257.
731 tstodr: make it work on s390 platform.
733 New icu iterator-functions. The new icu_iter-functions makes it possible
734 to use ICU chains from many threads.
736 yaz-client: better syntax check for show command.
740 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
743 New simple local-file XML include facility which allows file glob-patterns.
744 Refer to yaz/xml_include.h.
746 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
749 ZOOM_record_get supports new parameter "format" which makes it format XML
752 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
753 JSONText in ECMA-262) is JSONValue, not JSONObject.
757 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
758 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
760 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
761 POSIX/Unix builds .so with major version 4.
763 Remove old LOG_-defines from log.h. They have been obsolete and
764 undefined by default for the last 5 years.
766 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
768 GFS: Remove socket (int *fd) from search_rr handler. The socket
769 descriptor ptr is a facility that allowed a search handler to supply
770 a socket which would serve as a callback - when search was complete.
771 This facility has now been in use for years.
773 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
774 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
775 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
776 returns 'const char *' rather than 'char *. The returned string is
777 read-only and should not be modified by applications. COMSTACK cs_close is
778 now a void function - it no longer returns int. No applications check for
779 the value and the implementations has always returned 0.
781 ZOOM: use size_t for scan hit counts and str size. Functions
782 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
783 occ (hit count) and len (string length) are now of type size_t pointer
784 rather than int pointer. This is to be able to represent large hit counts
785 and to also just to use the proper type for string length (strlen result).
787 New JSON parser. Refer to include/yaz/json.h .
789 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
790 Used to be int in some cases. Many wrbuf_-functions used to return an int
791 indicating some length.. These return values were never used. And so they
794 ODR: odr_malloc, odr_total now takes size_t for size.
796 clone_z_type: fix leak; occurred for encoding failures.
798 --- 3.0.52 2009/12/03
800 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
801 bug was introduced in 3.0.51.
803 --- 3.0.51 2009/12/02
805 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
807 tcpip comstack: fix leak for getaddrinfo.
809 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
810 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
811 Decoding of SRU "path" database is performed by private function
812 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
813 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
815 yaz-client: honor base command for SRU. Change when database setting
816 is applied for SRU and ensure it is kept when a connection is reset.
817 Change also the way errors are displayed or SRU (decoding of packages).
819 --- 3.0.50 2009/11/02
821 Add support for extra request / response data for SRU codecs and GFS.
822 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
823 for extra data response buffer and length. For the GFS, both request
824 and response data (XML) is carried in extra_args and extra_response_data
825 for the search handler. Patch by Ko van der Sloot.
827 ZOOM: For queries that cannot be converted to the specified rpnCharset,
828 ZOOM now returns a diagnostic on the client-side ('invalid query' /
829 10010). This fixes bug #2113.
831 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
832 cmdfile included a 'quit' command that would result in a memory violation.
834 --- 3.0.49 2009/10/01
836 Make a number of functions defined in xmlquery.c static. These have
837 never been declared in a public header file (yaz/xmlquery.h) and was
838 made public by mistake.
840 Improve speed of character conversions (iconv utilities). This makes
841 conversions from MARC-8 faster.
843 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
844 unless type desired is "raw". This will prevent type "xml" from
845 returning ISO2709 .. Which obviously can not be XML parsed.
847 Fix memory leak in ZOOM that would occur if option apdulog was used
848 on a re-used connection.
850 Frontend server logs HTTP requests.
852 Frontend server now sends Z39.50 close when it times out (sesssion has
853 been idle for too long). Versions 2.0.30 and earlier also sent close.
854 But due to a mistake this was disabled in all versions after that, i.e.
855 the server would just close the socket immediately.
857 yaz-client emits a better message when receiving an unrecognised
858 userInformationField.
860 Skip zero-length subfields when decoding ISO2709. This rare case happens
861 if a record has two FS characters in a sequence. Without this patch
862 there would be a reference beyond char array in using_code_len fragments
865 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
867 --- 3.0.48 2009/08/28
869 The show command offered by the zoomsh command now takes a 3d optional
870 parameter type which is what is passed to ZOOM_record. If the type
871 argument is omitted, "render" is used.
873 RPN to CQL conv may use USE string attributes (bug #2978).
875 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
877 --- 3.0.47 2009/07/08
879 Function yaz_xml2query allows a diagnostic element in the PQF XML
880 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
881 code and additional info respectively.
883 The BER BOOLEAN is now the integral type Odr_bool which still happens
884 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
885 typedef'd to Odr_int. This is still an integral 'int', but it may be
886 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
887 ASN-1 compiler as well as programs has been updated to use the new types.
889 --- 3.0.46 2009/06/08
891 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
892 only the bibliographic record was rendered. For type=opac, an OPAC
893 record is only returned if it is present.
895 iconv: small fix for encoding of advancegreek.
897 yaz-client: avoid double display of SRU/SRW records (bug #2798).
899 yaz-client: option auto_reconnect=on really reconnects.
901 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
903 server: avoid null ptr ref for for yaz_poll errors.
905 build: fix RPM build for RHEL 5.3.
907 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
909 --- 3.0.45 2009/03/31
911 Fixed bug #2709: TCP connect returns Invalid argument.
913 Fixed compilation for mingw.
915 Honor charset for raw records (ZOOM_record_get).
917 Fixed use of errno for threaded mode that was seen on Solaris 10.
919 Fixed argument passing with blanks in value for Windows Service.
921 Disable YAZ' own log rotate by default (no 1 GB limit).
922 The variable l_max_size which specifies the log file limit is set to 0
923 (DISABLED): This is due to the fact that YAZ is most often deployed using
924 logrotate. Also YAZ can not perform log rotate because of unsufficient
925 permissions (setuid).
927 --- 3.0.44 2009/02/17
929 List supported encodings in man page for yaz-iconv.
931 Fixed missing SSL libs for --libs output
933 Re-established OID record syntax application-xml. Nobody should use it
934 but we don't want to change soname because of this symbol being absent.
936 --- 3.0.42 2009/02/02
938 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
940 Added member named_result_sets for init handler struct for the GFS. This
941 allows a server to disable named result sets.
943 Removed OID record syntax application-xml.
945 Added support for rule-based transliterator for ICU wrapper of YAZ.
947 Fixed bug #1902: yaz-icu XML output.
949 Make YAZ checks Emacs friendly.
951 BITSTRING value shows value. Bug #2346.
953 ISO2709 decoding: skip control characters from indicator data.
955 Omit sort key by default in yaz-icu's output.
957 Allow combined single char options (again) for YAZ' options function.
959 Utility yaz-marcdump got option to display YAZ version (-V).
961 Allow YAZ to use ICU 3.4.
963 Added new ICU test case which illustrates removal of diacritics.
965 --- 3.0.41 2008/12/29
967 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
969 --- 3.0.40 2008/12/29
971 For configure, using option --without-xml2 also disables Libxslt/Libexslt
974 Fixed bug #2352: yaz-marcdump crashes for certain record.
976 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
978 Added support for Danmarc2 to UTF-8 conversion.
980 Added support for ISO5426 to UTF-8 conversion.
982 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
983 implementation version.
985 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
987 --- 3.0.38 2008/11/10
989 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
990 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
992 ZOOM C now interprets databaseName option for ZOOM connection as path
995 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
997 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
999 Dummy Libxml2 types no longer defined in headers of YAZ'.
1001 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1004 --- 3.0.36 2008/09/26
1006 Various ODR chapter fixes.
1008 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1010 Added missing source for Windows compilation, mutex.c.
1012 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1014 For SRU connections in ZOOM all records up to "count" are now fetched.
1016 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1017 in Windows due to bad error handling for Libxml2.
1019 Added facility for sending arbitrary records (ASN.1 any) using
1020 ZOOM C's Extended service update. Patch by Sam Reynolds.
1022 New options for ZOOM C's connection, logapdu which makes ZOOM log
1025 --- 3.0.34 2008/06/18
1027 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1029 --- 3.0.32 2008/06/12
1031 Fixed memory violation that could occur when decoding UTF-8. This bug
1032 was only present in 3.0.30 of YAZ.
1034 --- 3.0.30 2008/06/06
1036 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1037 GNU TLS is used by default (if found).
1039 yaz-ztest returns OPAC records if a client asks for OPAC.
1041 Improved speed of MARC-8 encoding.
1043 Added support for lossy and loss-less MARC-8 encoding.
1045 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1047 Added new Windows Service wrapper (sc).
1049 yaz-client's itemorder command may now send a file.
1051 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1053 Added new function yaz_log_xml_errors.
1055 Allow (but warn) unknown XML attributes in MARCXML parsing.
1057 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1059 The UTF-8 to MARC-8 conversion now uses a different set of characters
1060 for Greek symbols. Bug #2120.
1062 --- 3.0.26 2008/02/21
1064 Added yaz_daemon (daemon.h).
1066 Fixed bug #2068: pkg-config trouble
1068 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1070 --- 3.0.24 2008/01/28
1072 Document --with-xml2 option.
1074 Added OPAC XML XSD (etc/opacxml.xsd).
1076 Allow glob mask for name attribute in retrieval element for the
1077 generic frontend server's retrieval facility.
1079 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1080 except POLLIN/POLLOUT.
1082 Fixed error handling in cs_listen. Bug #2037.
1084 --- 3.0.22 2008/01/20
1086 Fixed version in yaz/yaz-version.h.
1088 Fixed bug #2027: Crash when closing connection.
1090 Changed configure so that ICU support is only enabled if only ICU
1091 and Libxml2 is available (because the ICU chain is XML based).
1093 --- 3.0.20 2008/01/15
1095 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1096 is built. Only this DLL depends on the ICU runtime.
1098 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1099 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1101 Changed license of CCL module to 'Revised BSD'. After consultation with
1102 remaining members of the original EUROPAGATE consortium, we are re-issuing
1103 the CCL module without a separate license. The software was developed by
1104 Index Data as part of a research project. The special license was included
1105 to help feed usage information back to the project consortium to support
1106 project evaluation. At this time, the project consortium has long-since
1107 disbanded, and the majority of the original principals have retired. At the
1108 same time, we have significantly modified the software during the following
1109 years, to the point where very practically no original code remains. To
1110 simplify re-use of the software, we have contacted those members of the
1111 consortium who could be reached, and agreed to re-issue the module as a
1112 proper part of the YAZ package.
1114 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1116 CQL closer to being version 1.2 compliant. CQL also allows free-form
1117 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1120 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1121 bug could make Extended services handling crash in the ZOOM layer. This
1122 bug was only present in YAZ 3.0.18.
1124 --- 3.0.18 2007/12/19
1126 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1129 yaz-marcdump reads and writes collection wrapped records.
1131 Handle OPAC for record conversion module.
1133 Fixes for ICU wrapper.
1135 Allow ICU libs to be controlled with --with-icu .
1137 --- 3.0.16 2007/11/12
1139 Added yaz_poll which is a wrapper for select/poll. When poll is available
1140 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1141 sockets to be in use.
1143 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1144 functionality through an XML based configuration (ICU chain). This system
1145 is useful for search facilities such as Pazpar2 and Zebra that needs to
1146 perform tokenization of indexed material. The ICU code in a separate
1147 library libyaz3_icu.a.
1149 Added HTTP tunnel facility for COMSTACK, bug #1752.
1150 This is a facility that allows a Web proxy, such as squid, to tunnel
1151 Z39.50 traffic. This facility is "transparent" to must applications
1152 using YAZ. It's enabled by using pseudo transport connect: followed by
1153 the proxy address, followed by command, then follwed by he regular
1154 "virtual" addresss. For example,
1155 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1157 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1159 --- 3.0.14 2007/09/21
1161 Fixed bad memory reference in ZOOM_record - cuased by member not being
1162 initialized. This was a problem only in YAZ 3.0.12.
1164 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1165 fields were not removed.
1167 Changed the way C code is generated from codetables.xml. Made a MARC-8
1168 conversion trie for each characterSet section rather than codeTable.
1169 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1170 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1172 --- 3.0.12 2007/09/12
1174 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1175 from ZOOM_record_error).
1177 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1179 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1181 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1183 Better SRW-to-Bib-1 diagnostic mapping.
1185 ZOOM C and yaz-client announces SRU version 1.2 by default.
1187 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1190 Fixed in yaz_sru_decode to allow other version than 1.1.
1192 --- 3.0.10 2007/08/22
1194 Added support for SRU scan for ZOOM.
1196 Added support for the use of the older versions or Extended Service
1197 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1198 set to the version , 1=first, 2=second, 3=third. The third version is
1199 what ZOOM C has used so far. And that, obviously, is the default.
1201 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1202 therefore in Zebra and in SimpleServer-based applications). The new
1203 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1204 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1205 which is passed into the back-end search callback function.
1207 Added support for HTTP Basic authentication in clients: the SRU/W
1208 codec encodes the username/password elements of the PDU structure
1209 appropriately, and these may be set using the "user" and "password"
1210 options in ZOOM-C applications (the same options that are used for
1211 Z39.50 authentication).
1213 --- 3.0.8 2007/06/25
1215 Fixed bug #1208: SSL appears to be broken in ZOOM.
1217 Fixed bug #1206: Libxml2 include path weirdness.
1219 Added oid_name_to_dotstring.
1221 Allow elementSetName to be specified for ZOOM C record update.
1223 Allow waitAction to be specified for ZOOM C based for Extended Services.
1225 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1226 syntax OID. Bug introduced in YAZ 3 series.
1228 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1230 --- 3.0.6 2007/06/06
1232 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1233 directory. yaz-client now reads commands from file given by option -f
1234 if specified; then tries to read .yazclientrc in current directory.
1235 Failing that, it reads .yazclientrc from user's home directory.
1237 Added support for correlationInfo Note and ID for Record Update via
1240 Added yaz-client command querycharset which specifies character set for
1241 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1242 (termListAndStartPoint).
1244 Charset ISO5428:1984 is an alias for ISO5428-1984.
1246 Implemented a way to perform scan in a result set using Z39.50. This
1247 is achieved by attaching the result set name in the characterInfo
1248 (type InternationalString) of OtherInformation in the Scan Request PDU.
1249 The result set is identified in the otherinformation by the new OID:
1250 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1251 This allows for scan in result set and faceted search . Zebra did some
1252 of this in the APT term using attribute type 8 and value being result
1253 set. Using the OtherInformation approach for this is cleaner and easier
1254 to work with in proxies and the like. This facility can be used in
1255 yaz-client using new command setscan which takes a result set as first
1256 argument, start position (APT) as second.
1258 Changed decoding of SRU XML packed records to deal with servers that
1259 have recordData with XML data with multiple root nodes. Also make
1260 comparison for recordPacking case insensitive. Again, one server
1261 returns "XML" where others return "xml".
1263 For SRU responses allow Content-Type application/xml as well as text/xml.
1265 --- 3.0.4 2007/05/21
1267 Fixed bug in character set conversion of BER strings. Bug introduced
1270 --- 3.0.2 2007/05/08
1272 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1274 For OID class, use oid_class consistently.
1276 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1279 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1280 character set for bibliographic information interchange". By Giannis Kosmas.
1282 Added documentation on new OID API.
1284 --- 3.0.0 2007/05/02
1286 Changes to generic frontend server interface: added new member
1287 'query_charset' for bend_initrequest structure. A backend init handler
1288 should set this member to its native character set for query terms.
1289 When defined, the frontend server logic will announce this character set
1290 to a client if the negotiationModel bit is set by the client. All server
1291 implementors are encouraged to specify this. If a backend server does not
1292 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1294 Added CCL utility to remove terms (stop words) from resulting RPN
1295 tree. This is handled by functions with prefix ccl_stop_words_ .
1297 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1298 terms in RPN queries.
1300 Clean-up the CCL API. Moved some internal structures from ccl.h to
1301 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1302 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1303 This is replaced by ccl_parser_find_str which takes a string instead.
1305 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1306 libyaz.la is the core of YAZ except the generic frontend server and
1307 does not depend on POSIX threads anymore. libyaz_server.la is the
1308 generic frontend server facilities and uses POSIX thread functionality
1309 if available. The libyaz.la no longer depends on POSIX threads because
1310 the number of global structures is limited. NMEM no longer re-uses blocks
1311 between threads ; it simply free's memory immediately but allocates in
1312 "large" chunks as usual. We don't expect any performance penalties
1313 because of this. The yaz_log system is still using a global log_level so
1314 caution must be taken when modifying it with yaz_log_init_.. +
1315 yaz_log_mask_str. This, however, should not cause any trouble because
1316 these functions are called during initialization of application code
1317 anyway. `yaz-config --libs server` returns libs for server applications;
1318 `yaz-config --libs` returns libs for non-server applications.
1320 New OID database - with public definitions in oid_db.h. Removed old OID
1321 database including the head oid.h and definitions such as enum oid_value
1322 and struct oident. The new OID database uses the same string names as
1323 before but the 'protocol' is gone. There are now only two representations
1324 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1325 converts from string to OID; functions with prefix yaz_oid_to_string
1326 converts the other way.
1328 Change to emit_term() in CQL-to-PQF query translation: when a term has
1329 the /regexp relation modifier, do not process it for leading and
1330 trailing "^" and "*", which have quite different meanings in regular
1333 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1334 write handlers no longer carries a 'last' parameter. This will make
1335 yaz_iconv flush "less" characters. A flush is performed by call to
1336 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1338 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1339 removed, because function yaz_query_to_wrbuf does the same.
1341 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1342 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1344 Deprecated MARC utility functions removed.
1346 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1349 Branch split: YAZ_2_1_55_branch
1351 --- 2.1.54 2007/03/16
1353 Fix to ZOOM-C so that transparent reconnection is properly handled on
1354 connections that are in asynchronous mode.
1356 Fixed compilation on OpenBSD 4.0.
1358 Large strings in GRS-1 records are now properly displayed in yaz-client.
1360 Added character conversion support for "advancegreek"; based on patch from
1363 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1364 sequence is met. Before the error was not set so it would be unknown.
1366 Adjust yaz-marcdump MARC reader so that it skips until record separator
1369 --- 2.1.52 2007/03/07
1371 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1372 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1373 fd_set structure used as a bitmask for the FDs to be selected on.
1375 Using ACX_PTHREAD macro to check for POSIX threads.
1377 Fixed have-vsnprintf check.
1379 --- 2.1.50 2007/02/23
1381 Fixes for configure on BSD. Bug #900.
1383 Added snprintf/vsnprintf wrappers for systems that don't have
1384 limits (heavens forbid).
1386 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1387 created before all previous tasks were completed and removed from the
1388 task queue, the new task could be removed by a mistake.
1390 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1392 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1394 Fixed bug #832: Problem with MARC/charset in yaz-client.
1396 Fixed bug #668: save command line history for yaz-client.
1398 Fixed bug #830: pkg-config support.
1400 --- 2.1.48 2007/01/23
1402 Extended ZOOM result set options with two options that may be read by
1403 a client: resultSetStatus and presentStatus with values as specified for
1405 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1407 Fixed bug #827: Using SSL fails on Debian etch.
1409 Fixed bug #826: Weird looking chars for set of MARC records.
1411 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1412 that is treated as an ItemOrder with itemRequest being an XML document
1413 external. The value of "doc" is the content.
1415 Extended the GFS search facility. New member of bend_search_rr
1416 'estimated_hit_count' signals that hits is known to be an estmate
1417 (higher or lower than real hit count). New member 'partial_resultset'
1418 signals that the search was partial (hit count is lower or equal than
1419 real hit count). For Z39.50, the information is stored in resultSetStatus
1420 member of SearchResponse APDU. For SRU, the information is signalled
1421 via SRU diagnostic 59: "Result set created with valid partial results
1424 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1426 --- 2.1.46 2007/01/13
1428 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1430 Added ZOOM_connection_peek_event.
1432 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1433 the following new functions:
1434 ZOOM_event_nonblock, ZOOM_connection_process,
1435 ZOOM_connection_get_{socket,mask,timeout},
1436 ZOOM_connection_fire_event_{timeout,socket}.
1437 The existing blocking event handler, ZOOM_event, is a wrapper for the
1438 + blocking ZOOM_event_sys_{poll,select}.
1440 Implemented function ccl_xml_config which parses XML version of CCL
1441 configuration (bug #798).
1443 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1445 Added timings utility (yaz/timing.h)
1447 --- 2.1.44 2007/01/03
1449 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1452 Fixed bug #779: Rotation of apdu.log fails.
1454 Fixed for character set conversions:
1455 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1456 Honor G1 set in MARC-8 decoding.
1458 --- 2.1.42 2006/12/17
1460 Fixed bug #775: char conversion does not handle Alternative UTF-8
1463 Implemented function yaz_marc_read_line which parses MARC line format
1464 records. There is a wealth of formats out there. So far, this function
1465 reads line records produced by yaz_marc_write_line.
1467 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1468 more generic and easier to remember(!) options: -i format and -o format
1469 which specifies input format and output format respectively - where
1470 format is one of "marc", "marcxml", "line", "marcxchange".
1472 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1473 does not print anything except warnings for records.
1475 For yaz-marcdump, added support for MARC split into files (-s) with a given
1478 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1479 spec, at http://www.loc.gov/standards/sru/record-update/
1480 This has changed the binary layout of the following structs:
1481 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1482 bend_update_rr . Patch by Ko van der Sloot.
1484 Added GFS utility function bend_assoc_is_alive which returns 1 if
1485 association is still alive (client is connected); 0 otherwise (client
1486 closed connection). This allows busy servers to stop working for
1489 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1490 been a separate piece of software. This version of ziffy has been modified
1491 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1493 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1495 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1496 Client code may now interrogate options such as "init_opt_sort" to
1497 find out whether the server claims to support various options.
1499 --- 2.1.40 2006/11/27
1501 Added utilities yaz_{set,get}_esn to set/get element set name from
1504 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1505 of YAZ and has been so since YAZ 2.1.10.
1507 Implemented ZOOM_record_error which returns error information for
1508 record (surrogate diagnostic).
1510 --- 2.1.38 2006/10/31
1512 Updates for SRU Update by Ko van der Sloot:
1513 1. Changed name from "operation" to "action"
1514 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1515 versions in the code, marked as 'backward compatible'.
1516 3. Added diagnostics for SRU Update.
1518 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1520 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1522 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1524 For GFS, fixed problem with SRU diagnostic 'First record position out of
1525 range' being issued for 0 hits.
1527 zoomtst10 part of Windows Build.
1529 --- 2.1.36 2006/10/13
1531 Implemented yaz_filepath_comp which splits a path into file path
1532 components (required by Zebra 2.0.3+).
1534 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1535 BSD inspired license until now so this should not have any real impact on
1536 anybody. See http://www.opensource.org/licenses/bsd-license.php
1538 Fixed bug #687: Missing log lines.
1540 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1543 Fixed bug #689: SRU diagnostics to be added.
1545 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1546 whether a connection is idle (no more work do do).
1548 --- 2.1.34 2006/10/04
1550 Change type of optval from long to int for invocation of setsockopt with
1551 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1553 Added support for specifying the max log file size for the Generic
1554 Frontend Server. The size is given with option -r.
1556 --- 2.1.32 2006/09/21
1558 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1560 --- 2.1.30 2006/09/17
1562 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1565 Fixed bug in Generic Frontend Server that could cause a server to stop
1566 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1568 For the generic frontend server, the maximum record size is used as maximum
1569 size of incoming packages (SRU + Z39.50). The value until was previously
1570 only used in Z39.50 Init negotiation and, later, in a session controlled
1571 sizes of records returned. This is controlled using -k option. It can be
1572 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1574 --- 2.1.28 2006/09/04
1576 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1579 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1581 New option for yaz-marcdump -lpos=value which allows setting a portion
1582 of MARC header to a certain value.
1584 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1586 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1587 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1589 --- 2.1.26 2006/08/15
1591 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1594 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1596 --- 2.1.24 2006/08/08
1598 Fixed MARC ISO2709 encoding routines to deal with character set
1601 Minor changes to GFS logging. Database included in search request log
1604 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1605 cached/multiple records.
1607 Shared libraries are built by default on Unix+configure.
1609 Changed cql2pqf transformation to use a different evaluation order. The
1610 new order is: always, relation, structure, position, truncation, index
1611 and relationModifier. Old order was: always, relation, relationModifier,
1612 structure, index, position, truncation. Note that the the latter ones
1613 override former ones for identical attributes.. The new scheme means that
1614 it is possible to override any existing attribute with a relationModifier.
1615 And also that it is possible to override everything for the index rule
1616 (except the ones listed in relationModifier). No order is perfect but this
1617 one, we believe, covers more real cases.. The "always" should have been
1618 called "default", since the attributes there can be overridden with all
1621 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1622 compilation phase, but also for yaz-config --cflags output. This allows
1623 us to have public headers with Libxml2 stuff in them . It should also,
1624 eventually, make Libxml2 checks redundant in packages using YAZ, such
1627 --- 2.1.22 2006/06/15
1629 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1630 stored in uri, message and details.. Previously diagnostics were stored
1631 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1632 compatibility.. but he's probably the only one affected, so.
1634 Added support for CCL, compiled on the client side, in ZOOM-C. This
1635 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1636 input; the resulting query objects can be used for for searching with
1637 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1639 YAZ' configure searches for OpenSSL by default.
1641 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1642 SL_CTX_use_certificate_file. See
1643 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1644 for more info. Thanks to Ko van der Sloot.
1646 --- 2.1.20 2006/06/02
1648 Bug #600: SRU GET, POST support for yaz-client. Introduced
1649 command 'sru' which selects method SOAP/GET/POST.
1651 Allow missingValueAction to be specified for the sortspec string -
1652 function yaz_sort_spec. By default, the missing value action is null.
1653 Use ! to specify "abort". Use = followed by stringvalue to specify default
1656 Ensured that Present-handler (if defined) is called in GFS before any call to
1657 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1658 searchRetrieve requests.
1660 Documentation for YAZ is now based on the Docbook XML/XSLT using
1661 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1662 is no longer depending on jade/openjade or docbook-to-man scripts.
1663 PDF is no longer part of the distribution - but can optionally be
1664 made using DSSSL/jadetex or FOP.
1666 Added retrieval handling support in Generic Frontend Server to support
1667 conversion between MARC/XML as well as XSLTtransforms. See
1668 etc/yazgfs.xml for an example.
1670 Added Authentication support to Generic Frontend Server in SRU
1671 mode. Authentication using HTTP Basic is supported, as is the use
1672 of 'x-username' and 'x-password' parameters in the request itself.
1674 Added support for a new character set MARC8s identical to MARC8 except
1675 that it converts combined characters to single Unicode characters in the
1676 Latin-1 range (when possible).
1678 --- 2.1.18 2006/04/24
1680 ASN.1 compiler 0.4: generates brief Doxygen file header for
1681 generated .h/.c files.
1683 Utility yaz_iconv now supports conversion to MARC-8.
1685 New facilities for the MARC module. The reading - and writing of
1686 content are separate methods for the yaz_marc_t handle. The following
1687 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1688 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1689 format). Write functions have prefix yaz_marc_write_.. The existing
1690 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1691 available. Removed support for OAI-MARC and simplexml (not the
1692 simplexml from PHP5).
1694 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1695 to be returned for this connection.
1697 --- 2.1.16 2006/03/31
1699 Allow multiple languages and charsets to be specified with
1700 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1701 negcharset iso-8859-1,utf-8
1703 Translation of proximity nodes from CQL into PQF now works.
1705 Moved to automake 1.8, 1.9.
1707 Added function yaz_log_set_handler which allows a log handler to be
1708 installed. This handler will be called for all log messages. Output
1709 to file is also produced; but that can be disabled by passing NULL
1710 fname to yaz_log_init_file.
1712 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1714 For SRW (including GFS), accept application/soap+xml as content-type
1717 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1718 produces NO stylesheet reference even if a default stylesheet is specified
1721 --- 2.1.14 2006/03/14
1723 Updated Windows package to include yazd.dll + yazd.lib for the
1724 Development component.
1726 If the environment variable YAZ_LOG is set, then it is used as a
1727 string indicating the default level of logging to use if not
1728 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1729 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1730 used as before. So, for example, to omit warnings from YAZ logging,
1731 export YAZ_LOG=-warn
1733 cql_transform() now map structure and other attributes before indexes,
1734 so that index-specific structures and other attributes can override
1735 defaults. So now a combination of mapping specifications such as:
1737 index.dc.date = 1=date-modified 4=5
1738 does the right thing.
1740 cql_transform() now also respects the "always" mapping specification,
1741 which establishes an initial set of attributes to be used for all
1742 terms except where overridden by more specific attributes associated
1743 with the index, relation or modifier.
1745 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1746 which mode to use; one of "post", "get" or "soap" (SRW, default).
1748 Fixes for yaz_iconv routines: changed trie-based character set conversions
1749 to use only non-negative values for bit fields due to Sun's C compiler not
1750 supporting negative values.
1752 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1753 sequences where not read correctly. Fix by Rustam Usmanov.
1755 Updated win/makefile to use options, settings which makes things
1756 compile with VS C 2005.
1758 --- 2.1.12 2006/02/01
1760 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1762 In ZOOM socket code, use select instead of poll on MacOSX.
1764 ZOOM-C now support client-side compilation of CQL into RPN that is
1765 sent to the server, enabling CQL to be used against all Z39.50
1766 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1767 ZOOM_query object, and submit it using ZOOM_connection_search().
1768 The CQL-to-RPN translation uses a configuration file, the name of
1769 which must be specified in the Connection's "cqlfile" option.
1771 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1772 function, which takes as its start-term parameter a ZOOM_query object
1773 (which may have had either CQL or RPN set into it).
1776 --- 2.1.10 2005/11/29
1778 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1779 GFS to support this as well. Backend handler, bend_srw_update, does the
1780 update work. Code contributed by Ko van der Sloot.
1782 Allow retrieval of Search Result-1 information in ZOOM by the use of
1783 options that are attached to a result set. ZOOM documentation updated
1786 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1787 UTF-8 conversion. Patch by Raj Patel.
1789 Added option -m to GFS to control formatting of timestamps in log file.
1791 Added 'exit' as synonym for 'quit' in yaz-client
1793 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1794 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1795 for the new members. Patch by Ko van der Sloot.
1797 Added support for SRU POST. It is supported for content-type
1798 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1800 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1801 Instead make the library libyaz.la multi-threaded. Threading as a whole
1802 can still be disabled by configure option --disable-threads. Previosly,
1803 with older GLIBCs there were problems with MT libs under Apache. This
1804 has now been fixed a long time ago.
1806 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1809 CQL module modified to be case insensitive for relations/indexes/operations.
1811 Fixed bug in CQL transform code: incorrect value relationModifieder
1814 Added 'show all' command for yaz-client which retrieves all results
1817 Added new yaz-client, xmles, which takes a (private) OID and
1818 a document to be sent as an extended service request.
1820 Describe new yaz-client commands wait_response and set_auto_wait.
1822 Increase TCP/IP listener backlog from 3 (which I am guessing was
1823 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1824 that the socket will queue as many incoming connections as it's able
1825 to handle ongoing connections. In other words, it will never now
1826 refuse a connection that it would be able to handle merely because
1827 it's not got around to accepting() enough of the pending connections
1828 yet. This is the behaviour anyway under Linux, where the listen()
1829 argument is ignored; but not under BSD and on systems such as
1830 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1831 YAZ-based servers should now be uniform across operating systems in
1834 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1835 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1836 This allows yaz-marcdump to read large MARC batches (>2 GB).
1838 Modified all YAZ source files - except the source which is auto-generated
1839 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1842 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1843 corresponding to the existing *_setl() function. These allow option
1844 values containing arbitrary valuues.
1846 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1847 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1848 except that it returns an indicator of whether or not the sort
1849 criterion was accepted (0 for OK, -1 for invalid).
1851 --- 2.1.8 2005/06/07
1853 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1854 MARC output rather than returning "new" buffer.
1856 yaz-client warns about unknown init options.
1858 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1860 --- 2.1.6 2005/05/24
1862 Added support for SRW sort in Generic Frontend Server. Patch
1863 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1864 sortKeys - or NULL if none is provided.
1866 Fixed bug #307: It was impossible to specify indefinite/no timeout
1867 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1870 Added support for multiple languages and charsets to be specified in
1871 ZOOM. Each charset/language is separated by a blank. If negotiation is
1872 in effect in init-response, Option
1873 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1874 Code based on patch by Vasiliy Osadchuk.
1876 Fixed bug #306: infinite recursion that occurred when calling
1877 yaz_log_level_init as the first call (before other log level or
1880 Fixed bug in scan handling in front end server: if preferred-Position-In-
1881 Response was non-present, a NULL pointer referece was performed.
1883 --- 2.1.4 2005/04/26
1885 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1886 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1887 now defined for all those error codes. So instead of putting 109 in
1888 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1889 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1891 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1894 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1896 Program yaz-client now exits and produces an error message if multiple
1897 Z39.50 servers are specified on the command line (none or one allowed
1900 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1903 --- 2.1.2 2005/03/16
1905 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1907 Fixed bug #272: Preserve spacing for CCL terms.
1909 --- 2.1.0 2005/03/14
1911 Added support for virtual hosts and multiple backend servers for
1912 the YAZ frontend server. The configution is XML based and
1913 support specificition of CQL to RPN mappings and explain information.
1914 See section "Virtual Hosts" in the YAZ manual.
1916 Extended OPAC display utility. OPAC display utility renders
1917 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1918 to supplement yaz_marc_decode_wrbuf.
1920 Fixed a bug in MARC decoder that could caused it to crash for some
1921 invalid MARC records. More diagnostics and warnings where added in
1922 XML output (warnings, etc are stored in comments).
1924 --- 2.0.34 2005/02/08
1926 Fixes for UNIX domain sockets. Bug #261.
1928 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1930 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1931 Added yaz_marc_subfield_str which defines subfield lead string which is
1932 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1933 yaz_marc_endline_str which defines end of fields string used in
1934 YAZ_MARC_LINE format. Default string is newline.
1936 Experimental support for MarcXChange. This format can be produced
1937 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1938 http://www.bs.dk/standards/MarcXchange.xsd
1940 Added yaz-client commands scansize that sets maximum number of
1941 entries to be returned by scan.
1943 --- 2.0.32 2005/01/11
1945 Added support for SRW scan in yaz-client and Generic Frontend Server.
1947 * Added whereInList member to SRW Scan Term.
1949 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1951 Fixed NMEM system to return aligned blocks on the smallest boundaries
1952 that are suitably aligned for all possible types on the particular
1953 architecture YAZ is being built for.
1955 --- 2.0.30 2005/01/04
1957 Fixed numerious warnings that was issued with newer versions of GCC.
1959 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1960 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1963 Make YAZ Generic Frontend Server slightly faster.
1965 Enhance (and reduce) logging for Generic Frontend Server.
1967 Revert YAZ log system so that it flushes every write operation
1968 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1970 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1971 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1972 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1973 will effectively disable old definitions.
1975 --- 2.0.28 2004/11/09
1977 Added yaz_log_time_format which specifies log format using
1980 Added yaz_log_module_level which returns mask for a module. Value
1981 is non-zero mask a if module is enabled; zero if disabled.
1983 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1984 in include/yaz/cql.h.
1986 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1988 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1990 Fixed bug #172: RPM builds does not enable SSL.
1992 Doxyfile.in part of dist. Doxyfile generated by configure.
1994 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1995 are given and the corresponding component does not exist.
1997 Extend CCL documentation in YAZ reference. Describe r=r.
1999 --- 2.0.26 2004/10/01
2001 Fixed MARC->MARCXML conversion to properly deal with
2002 fields, subfields, indicators having non-ASCII characters.
2004 Fixed MARC->MARCXML conversion so that ASCII control characters
2005 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2008 Added YAZ GFS support for conversion from Z39.50 surrogate
2009 diagnostics to SRW surrogate diagnostics.
2011 Bug fix: YAZ GFS did not return schema in explainResponse.
2013 --- 2.0.25 2004/09/30
2015 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2016 now converts recordSchema to elementSetName as well as schema URI.
2018 Fixed bug in COMSTACK that prevented HTTP request packages from being
2021 --- 2.0.24 2004/09/29
2023 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2024 does not require white-space before and after the dash in a range, e.g.
2025 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2028 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2029 due to new GCC removing "redundant" code.
2031 Added yaz-client commands scanpos and scanstep that sets preferred
2032 position and step-size for scan.
2034 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2036 Added CCL utility ccl_qual_buf which parses one or more CCL
2037 spec lines in a buffer.
2039 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2040 of name and value - ignoring empty lines and comments.
2042 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2044 Added odr_get_element_path which returns current element path for an
2045 ODR handle. This utility is useful in error handling or user-defined
2048 Added ODR_PRINT utility odr_set_stream which is is a more generic
2049 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2050 to a write function and pointer to close function. The close function - if
2051 non-NULL - will be called during odr_destroy.
2053 Fixed bug in CCL parser where truncation char was not removed from
2054 right side when truncation=both was in effect.
2056 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2059 --- 2.0.23 2004/08/11
2061 Fix buffer overrun in CQL parser when dealing with proximity (%).
2063 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2064 to UTF-8/UCS conversion is now only based on codetables.xml.
2066 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2068 --- 2.0.22 2004/08/06
2070 Add support for more "commit changes" in ZOOM (uses Extended Services).
2072 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2075 Yet another small fix for configure of SSL.
2077 --- 2.0.21 2004/05/14
2079 Fix SSL libs for configure when --with-openssl=DIR is given.
2081 --- 2.0.20 2004/05/10
2083 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2085 SSL comstack now uses yaz.pem certificate file on server side
2086 by default. Certificate filename can be configured by calling
2087 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2089 Fix bug regarding multiple calls to ZOOM_connection_connect.
2091 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2093 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2094 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2096 ZOOM now allows inspection of X509 peer certificate for verification.
2097 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2099 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2100 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2101 as "modular" but it simplifies things.
2103 Added cs_get_peer_certificate to that returns peer X509 PEM.
2105 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2106 NULL if SSL is unavailable.
2108 Documentation about MARC decoding tools.
2110 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2112 --- 2.0.19 2004/03/30
2114 Rename CHANGELOG to NEWS to follow GNU style packing.
2116 Fix bug with missing initialization of member in init_diagnostics.
2117 This bug affects threaded version of GFS server.
2119 --- 2.0.18 2004/03/20
2121 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2124 Ensure zlib.dll is packed with Windows install.
2126 --- 2.0.17 2004/03/17
2128 Fix encoding of xsd:string to use text instead of CDATA.
2130 Fix endless loop in CQL parser with unbalanced ".
2132 Use a more compact way to store MARC-8 conversion tables.
2134 --- 2.0.16 2004/03/16 Debian only
2136 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2139 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2144 --- 2.0.15 2004/03/01
2146 Another fix for decoding of XML packed records.
2148 --- 2.0.14 2004/02/25
2150 Fixes for Chunked encoding. White space not ignored after length spec.
2152 Update NS and use default NS for SRW diagnostic elements.
2154 --- 2.0.13 2004/02/23
2156 Implement ZOOM_resultset_cache_reset which resets record cache.
2158 Implement ZOOM_resultset_sort which sorts a result set.
2160 Implement chunked HTTP transfer.
2162 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2164 --- 2.0.12 2004/02/16
2166 Added member 'schema' to bend_explain_rr structure so that backend
2167 can specify explain record identifier. Defaults to Zeerex 2.0.
2169 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2171 --- 2.0.11 2004/02/16
2173 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2176 Added init command for yaz-client which sends "extra" init request.
2178 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2179 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2181 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2183 Make ZOOM error code for "invalid query".
2185 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2187 --- 2.0.10 2004/02/05
2189 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2192 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2194 Added option -p <file> to make Generic Frontend Server to write PID file.
2196 Added option -D to put Generic Frontend Server in background on its own.
2198 Make ZOOM C recognize option "password". If unset, "pass" is used
2199 (for backwards compatibility).
2201 Fixed a bug in Generic Frontend Server that could make it crash if a
2202 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2205 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2206 Must be issued before open, in order to be in effect.
2208 --- 2.0.9-6 2004/01/12 Debian/Windows
2210 Make the SRU server more picky WRT unknown params, etc.
2212 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2214 New YAZ client command, options, that sets Z39.50 options.
2216 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2217 options from a string of tokens (one token for each option bit).
2219 Update SRW diagnostic code messages.
2221 --- 2.0.9-5 2004/01/07 Debian/Windows
2223 Handle user defined stylesheet for SRW/SRU.
2225 --- 2.0.9-4 2004/01/06 Debian/Windows
2227 Fix bug in decoding of Content-Length.
2229 --- 2.0.9-3 2004/01/06 Debian/Windows
2231 Fix a bug with decoding of XML packed records.
2233 --- 2.0.9-2 2004/01/05 Debian only
2235 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2237 Fix bug in SRW/SRU diagnostics decoding.
2239 --- 2.0.9 2004/01/05
2241 Fixed bug in Generic Frontend Server which could drop records exceeding
2242 preferred message size. Reported and fixed by Irina Dijour.
2244 Fixed calculation of package size for structured records in Generic
2245 Frontend Server. Reported and fixed by Irina Dijour.
2247 Fixed namespace for SRW/SRU diagnostics.
2249 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2251 --- 2.0.8 2003/12/22
2253 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2254 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2257 CQL changes to reflect recent changes to the specification:
2258 * Documentation talks about context sets instead of index sets.
2259 * Documentation talks about indexes instead of qualifiers.
2260 * The CQL-to-PQF transformer's configuration file now uses
2261 "index.set.name = <attributes>" instead of the old form
2262 "qualifier.set.name = <attributes>". (Both forms are still
2263 understood but the latter is deprecated.)
2264 * CQL terms with no explicit index specified are now interpreted as
2265 cql.serverChoice instead of srw.serverChoice (which of course
2266 behaves exactly the same.)
2268 --- 2.0.7 2003/12/16
2270 MARC conversion can now generate ISO2709 output in another
2271 character set. yaz-marcdump uses this facility if you invoke it
2274 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2275 functions from there can be used from C++.
2277 --- 2.0.6 2003/12/04
2279 Frontend server now transfers memory from decoded packages to stream
2282 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2283 references to show up.
2285 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2286 the ZOOM Abstract API. The older names for the same options are still
2287 also supported for the benefit of old applications.
2289 ZOOM-C supports "implementationId" and "implementationVersion" options
2290 to go along with "implementationName". These allow the user code to
2291 specify identification strings to be sent to servers.
2292 Add OID for the new ExtLite attribute set.
2294 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2295 as requested/supplid by Ere Maijala <ere@atp.fi>
2297 For generic frontend server, reverse the order of
2298 "toolkit-supplied / application-supplied" strings sent as implementationId,
2299 Name and Version. Also, remove the spaces around the slash. This brings
2300 the GFS in line with the behaviour of ZOOM-C on the client side.
2302 Add function ZOOM_scanset_display_term.
2304 yaz-client shows scan displayTerm if present.
2306 Utility yaz-iconv is now installed by default along with the man page
2309 Extend configure check for OpenSSL to use pkg-config where available (such
2312 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2313 server to specify uid/gid/mask for socket using the format
2314 unix:[user=uid,][group=gid,][umask=mask,]file=path
2315 If file= is omitted the existing format is assumed, e.g.
2317 in which case the mask is 0666 (rw for everybody).
2319 Major restructure of YAZ source. All source in libyaz is in src directory.
2320 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2321 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2323 Added man page for utility yaz-marcdump (used to be called marcdump).
2324 yaz-marcdump is installed by 'make install'.
2326 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2327 of incoming package failed.
2329 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2331 Change prototype of odr_perror: add const to message string.
2333 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2335 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2336 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2337 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2338 DNS lookup. There should not be any compatibility problems with this
2339 assuming that blocking=1 or 0 is used.
2341 Fix bad reference in UNIX comstack in function cs_addrstr.
2343 Fix for compilation on AIX.
2345 The generic front-end server (server/seshigh.c) now supports returning
2346 Init diagnostics to the client in User-information-field, in
2347 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2350 --- 2.0.4 2003/09/04
2352 Allow any CQL relation (not just all,any,exact,scr).
2354 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2355 that features the same UI.
2357 Implemented command update0 in YAZ client which is equivalent to
2358 update but uses old of Ext Update ASN.1.
2360 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2361 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2362 Previously no OID was used for this info.
2364 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2365 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2366 returns 'malformed search term' otherwise.
2368 SortResponse member resultCount now set to NULL in sort handler of
2371 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2374 Add three new utility functions for translating OIDs between various
2375 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2376 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2377 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2378 char *oid_to_dotstring(const int *oid, char *oidbuf);
2379 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2381 Reverted modifications for ES Update definition for z_IU0Update
2382 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2383 is back to YAZ 2.0.2.
2385 String value attributes for CCL parser.
2387 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2388 which their FirstSearch server returns in Init responses, sometimes
2389 carrying useful diagnostic information when Init fails. This has the
2390 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2391 "z39.50/oclcui.asn", where its definition is somewhat different from
2392 what OCLC document on their web-site, as required to interoperate with
2395 Support for anonymous authentication in yaz-client. Use the command
2398 * Fix the OID of the Index Data-local "admin" Extended Service from
2399 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2400 the 1000, which indicates a locally-defined OID, was a mistake.
2402 --- 2.0.3 2003/06/20
2404 Fix CCL directive @case handling so that it affects string match for
2405 both CCL keywords and qualifiers.
2407 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2408 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2409 Decoder has been updated with ASN.1 changes as listed in
2410 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2411 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2412 z_IUUpdate, remains unchanged.
2414 ZOOM_record_get may now return a record in a specific character set.
2415 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2416 "from" is the character set of record as returned by target. "to" is
2417 the character set to be returned. If omitted, "to" is UTF-8.
2419 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2421 New ODR utility, odr_getelement, which returns name of element for
2422 which encoding/decoding failed.
2424 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2425 in cases where a required element was omitted.
2427 Bug fix: some MARC8 sequences were not converted.
2429 New ZOOM option "step" which specifies number of records to be
2430 retrieved in one chunk. Used in conjunction with "start" and "count".
2432 SRW support for yaz-client. Use scheme http: to use it, e.g.
2435 yaz-client no longer does (un)intelligent character set conversions
2436 by default. Can be enabled with charset and marc_charset commands.
2438 xmalloc trace fix for 64-bit systems such as DEC alpha.
2440 Solaris 2.6 compile fix.
2442 New function, cql_strerror() translates SRW error codes, as returned
2443 by cql_transform_error(), into human-readable English strings. Used
2444 in yaz-client diagnostics when appropriate.
2446 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2447 converts it into a type-1 query which is sent to the server. This
2448 makes CQL available for use with all Z-servers, as opposed to the tiny
2449 minority that can handle CQL queries themselves.
2451 --- 2.0.2 2003/04/28
2453 New Debian package layout similar to the Redhat Package layout.
2455 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2456 and search result respectively.
2458 --- 2.0.1 2003/04/25
2460 Redhat package is now several packages: libyaz (runtime libraries),
2461 libyaz-devel (development and documentation, and yaz (utility programs).
2462 Package spec file by Morten Bogeskov.
2464 New member 'schema' in struct bend_fetch_rr which the name of requested
2465 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2466 handler MAY set this to reflect the schema of the returned record.
2468 New member 'display_term' in struct scan_entry. GFS now sets member entries
2469 and allocates scan entries to be filled by user scan handler. In previous
2470 version, entries member was allocated by the scan handler. That still works,
2471 but the GFS will ignore member display_term - assuming it was NOT set by
2472 the handler. The fact that the GFS now allocates the entries both allows
2473 for new members and makes a scan handler easier to write.
2475 Fix CQL lex buffer overflow.
2477 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2478 SRU default recordPacking is string.
2480 SRU protocol support for frontend server.
2482 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2484 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2486 Added scan for the ZOOM shell (zoomsh).
2490 * String Identifers for Schemas (Amendment 5).
2491 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2492 Old definition for schema
2493 Odr_oid *schema; /* OPT */
2498 Z_InternationalString *uri;
2499 #define Z_Schema_oid 1
2500 #define Z_Schema_uri 2
2503 * resultCount parameter to Sort Response (Amendment 1).
2504 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2506 Support for SRW 1.0 over HTTP. This is an optional feature and
2507 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2510 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2511 on the same port. SRW SearchRetrieveRequests are mapped
2512 to bend_init,bend_search,bend_fetch,bend_close.
2514 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2516 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2517 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2519 ZOOM connections are SRW based if schem http is used for hostname
2520 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2521 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2523 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2524 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2525 distance=n, order=true/false, relation=le, prox unit=word. If
2526 n is omitted, distance 1 is used.
2528 Fixed problem with C compiler include path in wrong order.
2530 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2531 on Solaris. Patch from Ko van der Sloot.
2533 New MARC decode API. All new functions operate on a yaz_marc_t
2534 handle. The most important new functions are: yaz_marc_create,
2535 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2536 decode and destroy respectively. Decoder can produce formats
2537 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2538 include/yaz/marcdisp.h.
2540 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2541 to UTF-8, UCS-32, wchar_t or Latin-1.
2543 * Prototypes for yaz_iconv_-functions moved to separate header
2544 include/yaz/yaz-iconv.h.
2546 Make a few private functions 'static' in unix.c. This prevents
2547 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2549 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2550 are set when Init Response is received.
2552 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2553 but returns diagnostic set as well.
2555 New function yaz_strerror which is a portable wrapper for
2556 strerror/strerror_r/GetLastMessage.
2558 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2559 is returned for MARC. If type is "oai", then OAI MARC is returned.
2561 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2564 --- 1.9.2 2002/11/26
2566 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2568 Fix bad race conditions on SIGTERM and terminate gracefully in
2571 Move retrieval (data1) module to Zebra since nobody seems to be
2574 Add GRS-1 render for ZOOM using same format as yaz-client.
2576 --- 1.9.1 2002/10/05
2578 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2580 Fix broken ESpec handling in data1 module.
2582 SGML reader parses comments and makes them part of the data1 tree.
2584 Added several type casts so that YAZ compiles as C++ code.
2586 ZOOM didn't handle PDU encoding failures properly.
2588 Added more Bib-1 diagnostics (approved extensions).
2590 GNU configure: better check for iconv.
2592 More portable use of accept, getpeername. Check for socklen_t. Use
2593 int/size_t if socklen_t is not defined.
2597 PQF parser rejects bad queries - including those with extra
2598 characters in them. PQF parser used to silently ignore that.
2599 Cleaner API for PQF added, which allows you to get detailed
2600 error information for bad queries (see yaz/pquery.h).
2602 Fixed bug in ZOOM_record_get for type "database".
2604 Implemented mini iconv library supporting conversions between
2605 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2607 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2609 --- 1.8.9 2002/08/20
2611 Fixed ZOOM C record cache so that preferredRecordSyntax and
2612 elementSetName is used to check for already fetched records.
2614 --- 1.8.8 2002/08/02
2616 Added three members in bend_initrequest structure to facilitate
2617 character set negotiation.
2619 Fixed a bug in frontend server that could cause indefinite
2620 loops under rare conditions.
2622 Revised character set utilities (charneg.h) so that encoding
2623 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2625 For PQF, directive @term <type> sets term type for Scan/Search.
2626 Here <type> is general, string, numeric, null. The term type
2627 is inherited - just like @attr.
2629 New call odr_set_charset that sets character set conversion for
2630 international-strings on a ODR stream. Prototype is:
2631 int odr_set_charset(ODR o, const char *to, const char *from);
2632 The InternationalString is still represented as C string in YAZ
2633 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2634 won't). On the protocol level, you can use any encoding.
2636 Support for UNIX sockets in ZOOM.
2638 Solaris recv sometimes returns errno == ENOENT. It is treated as
2639 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2641 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2642 both client and server. Code by Morten Bogeskov.
2644 --- 1.8.7 2002/05/22
2646 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2647 that they can be used directly from Visual Basic. You must recompile
2648 your windows APP if you're using ZOOM.
2650 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2651 Commands "lang" and "charset" sets language and character set respectively.
2652 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2653 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2655 Attributes from multiple CCL fields may be OR'ed rather than merged
2656 using directive "@field or". Fields are still merged by default -
2657 equivalent to "@field merge".
2659 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2662 Fixed bug in zget for parameter ExtendedServicesResponse.
2666 --- 1.8.6 2002/03/25
2668 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2670 Client displays USR.1:SearchResult-1 (hits per term).
2672 Additional Search Info for search in Generic Frontend Server.
2674 Fixed CCL parsing of "field=s".
2676 WIN32 installer - using the excellent NSIS software from nullsoft.
2678 Fixed CCL parsing of "field = - <number>".
2680 Added function yaz_marc_decode that decodes MARC for line mode
2681 display or XML (similar to that used by JZKit).
2683 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2684 Z39.50. But ISO/ILL was, however.
2686 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2687 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2689 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2690 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2692 --- 1.8.5 2002/02/03
2694 New YAZ client features: Command completion and new commands:
2695 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2696 Code provided by Jacob Poulsen.
2698 New call oid_trav, that visits all registered OIDs via callback.
2700 Function ZOOM_record_get now returns const char pointer rather than
2701 void pointer. It saves a lot of type casts.
2703 For YAZ client, command "auth" now allows you to set authentication
2704 in IdPass style. It is enabled when three tokens are given - order
2705 is user, group and password.
2707 Fix memory leaks in MARC record handling for ZOOM.
2709 New option for YAZ client, -k <kilobytes> that sets
2710 maximum record size. Similar to -k option for generic frontend
2711 server and yaz-ztest.
2713 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2715 Prefix query parser reports "fail" when bad attribute set is given.
2717 Fix in MARC decoder. Proximity logging. Fix for attribute set
2718 in scan handler for server. Patches by Shigeru Ishida.
2720 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2723 Configure option --with-openssl=<dir> now works when a directory is
2724 specified. Patch provided by Morten Bogeskov.
2726 New option for YAZ client, -u <auth>, that sets authentication.
2728 ZOOM fix: error information was sometimes "missing", since error
2729 was cleared/reset too when it shouldn't.
2731 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2733 --- 1.8.4 2002/01/04
2735 Scan for ZOOM API. New object ZOOM_scanset. New functions
2736 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2737 ZOOM_scanset_destroy.
2739 New ZOOM function, ZOOM_connection_last_event, that returns type
2740 of last event (such as "receive data", "send data", "apdu received",
2743 New ZOOM option, schema, that specifies schema for retrieval.
2745 New CCL feature. Qualifiers can be aliases for one or more
2746 other qualifiers (if more than one is given, OR is used).
2748 ZOOM uses named result sets if target supports it.
2750 Two new YAZ client commands: . (dot, which sources a script of YAZ
2751 client commands), and ! (to execute shell command.). Implemented
2754 Working on Debian packages.
2756 --- 1.8.3 2001/11/19
2758 YAZ client enables named result sets only if target supports it.
2760 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2762 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2763 with key="host" to get same result.
2765 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2766 Function Z3950_resultset_record(s) returns references to records
2767 "owned" by resultset. To become owner use Z3950_record_clone.
2769 Function z_ext_record handles Extended Services. Thanks to
2772 --- 1.8.2 2001/11/12
2774 CCL Parser fix: ignore token comma when dealing with and-lists.
2776 Documentation updates for COMSTACK.
2778 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2779 Changed prototype Z3950_records. For some functions, int parameters
2780 were changed to size_t.
2782 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2785 New MARC decode/display function, marc_display_exl, which properly rejects
2786 non-ISO2709 records. YAZ client uses it.
2788 --- 1.8.1 2001/10/29
2790 Fix bug: local attribute set wasn't set correctly in PQF strings.
2794 * Old Z39.50 codecs no longer supported.
2796 Added ZOOM C binding. See http://zoom.z3950.org/
2798 Renamed states for COMSTACKs to avoid confusion with events.
2800 Implemented cs_look and proper cs_rcvconnect.
2802 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2804 Configure detects POSIX threads on OpenBSD.
2806 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2807 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2809 When error is returned from present handler, non-surrogate diagnostic
2810 is returned in present response (and fetch handler is no longer called).
2812 * Minor adjustments to pquery parser (PQF). Token characters may be
2813 escaped by using backslash (C-style).
2815 PQF parser allows string attribute values to be specified. For @attr,
2816 non-numeric characters after the equal-sign are treated as strings
2817 (e.g. @attr 9=title).
2819 CCL trunction character may be defined (@truncation in file)
2821 * function zget_ExtendedServicesRequest sets waitAction to
2822 waitIfPossible (was wait).
2824 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2827 CCL operator names may be set in field definition files (CCL_bibset).
2828 See ccl/bib1 for an example.
2830 Fixes in ASN.1 compiler for C++ compatibility.
2832 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2833 and "op_or" to avoid conflict with C++.
2835 Fixed problem with GNU readline detection on Redhat 7.0.
2837 Added step-size for Scan backend handler.
2839 Fixed bug that made the frontend server crash when no attribute
2840 set was specified for scan.
2842 Front-end server automatically switches to original working directory
2843 when installed as an NT service. Previously -w had to be specified to
2846 Added extended attributes for retrieval module (data1), so that data1
2847 records carry d1_readXML/SGML attributes. d1_read also supports
2848 null-data rules ( <tag/>)
2850 On UNIX when POSIX threads are available, a separate library libyazthread
2851 is created. Programmers should link with that library and the yaz library
2852 when using threads. The reason for the split was that some applications
2853 on Linux, such as Apache, doesn't work well when using shared objects that
2856 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2857 (or any frontend server) in SSL mode by specifying ssl: followed by
2858 address. Only tested on UNIX.
2860 Added feature for CCL module. Virtual structure s=al or s=ol generates
2861 and-list and or-list respectively instead of phrase search.
2865 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2866 log_mask_str. This was done to avoid name conflicts with other libraries
2867 (such as other PHP extensions).
2869 Added raw OID member for preferred record syntax (request_format_raw)
2870 and returned record syntax (output_format_raw) for backend fetch method.
2872 Config file yaz-config now accepts options so that it returns specific
2873 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2875 Shared library support for UNIX using GNU libtool.
2877 * Modified backend interface. Request/Response struct's replaced by
2878 one read/write C struct. For example bend_fetchrequest and
2879 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2880 Every handler - even search has to be registered in bend_init
2881 handler. This means that the YAZ library no longer refers to
2882 external functions and it makes it possible to make the whole
2883 thing a single DLL/SO.
2885 Added Segment handler for backend server.
2887 Added Zmbol/Zebra administrative functions to YAZ client.
2889 Threaded frontend server on UNIX (when POSIX Threads are available).
2890 Starting the server with option -T enables multi-threading.
2894 Added configure option --enable-comp/disable-comp to control use
2895 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2896 located in sub directory asn.
2898 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2899 in ${exec_prefix}/bin along with the other programs yaz-client and
2902 GNU automake used to maintain makefiles.
2904 Added several OID's.
2906 Changed retrieval module so that we can load records with no abstract
2907 syntax defined. Tagpaths in these records are fully composed of string
2910 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2914 On UNIX, the generated makefile now supports a proper 'make install'.
2915 The prefix can be set via GNU configure to set the install location
2916 (default is /usr/local).
2918 * YAZ programs client and ztest were renamed to yaz-client and
2919 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2920 locations, such as /usr/bin,/usr/local/bin,etc.
2922 * YAZ Header files were moved from include to include/yaz. YAZ Header
2923 files are referred to as include <yaz/log.h> rather than <log.h>.
2924 The YAZ include path (-I ..) is therefore the same as before. Programmers
2925 should update their #include statements or use -Ipath/include/yaz
2926 instead. The main motivation for doing this change is that YAZ header files
2927 can be installed in "standard" locations /usr/include,/usr/local/include
2928 without introducing conflicts, since ALL YAZ header files are stored
2929 in subdirectory yaz (under /usr/include for example).
2931 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2932 rather than project/workspace files. We switched because project files
2933 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2936 Changed name of logging function, logf, to yaz_log, to prevent name
2937 clash with some math-log functions. The YAZ header log.h defines logf
2938 to yaz_log (#define) so there should be no incompatibilities by this
2941 Added bend_start/bend_stop handlers for server. These handler are
2942 called on start/stop of server. For windows they are called whenever
2943 a service is started/stopped.
2945 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2946 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2947 in util/yc.tcl. The auto-generated C code structures are, in a few
2948 cases, incompatible with the old decoders. There are differences in the
2949 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2950 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2951 The preprocessor variable ASN_COMPILED is defined when the compiled
2952 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2953 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2954 wish to use the old encoders/decoders you can specify --disable-yc
2957 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2958 version so that it supports both new - and old version of DB Update
2960 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2961 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2962 change. The name parameter can be set to 0 in which no name is specified
2963 for the construction. The macros odr_implicit and odr_explicit sets name
2964 parameter to zero for the construction involved. New macros
2965 odr_implicit_tag and odr_explicit_tag are similar to the others,
2966 except that a name parameter is added. For programmers' that don't use
2967 ODR they probably only need to change the call to z_APDU and z_External.
2969 Added access control facility by interfacing the TCP wrapper library.
2970 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2971 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2972 name of the daemon and enables the access control as specified in
2973 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2975 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2976 den Dool <H.M.vdnDool@kub.nl>.
2978 Added reference ID parameter to most functions in server API - refer
2979 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2981 Changed name of ccl library to libccl.a (was ccl.a).
2983 Fixed bug in decoder for Explain (Category TargetInfo).
2985 Added support for GNU readline in client. Thanks to Jacob Poulsen
2986 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2988 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2989 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2990 IMPLEMENTATION! This change was made to the development version before
2991 the ZIG decided to retract the amendment. If any users MUST be
2992 compatible with the original Update definition, PLEASE CONTACT US, and
2993 we will include a separate definition corresponding to the old Update
2994 ES. Note that because of the change to the ASN.1 of the
2995 TaskPackageRecordStructure we cannot define a single structure that
2996 will support both versions.
2998 * Added const modifier to buffer parameter for some ODR/BER encoding
2999 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3000 completeWAIS, odr_dumpBER.
3002 Fixed bug in client.c which caused a crash when a scanResponse didn't
3003 contain positionOfTerm.
3005 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3006 * will cause an error in a client if a non-YAZ target sends both a
3007 * list of Scan entries and non-surrogate diagnostics.
3009 Retrieval module enhancements. Tag sets may be typed in the reference
3010 to it. From the .abs-file the "tagset" directive takes a third optional
3011 integer type for the tag set referenced. From a .tag-file the "include"
3012 directive takes a third optional type as well. The old "type" directive
3013 in the tag set itself is still recognized but acts as the default type
3016 Backend interface change. Individual Scan terms returned from bend_scan
3017 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3018 in include/backend.h.
3020 Retrieval module enhancements. Multiple tag sets and attribute sets may
3021 be specified in abstract syntax specs. Revised the error/warning for
3022 logging messages reported by the retrieval module when reading the
3025 Object Identifier system (oid_..) changed. The API is backwards
3026 compatible but the oid-routines now allocates new OID's when needed.
3027 Raw OID's may be specified in oid_getvalbyname.
3029 YAZ now uses GNU configure to generate Makefile(s).
3031 * Minor changes in some of the member names of DeleteResultSetRequest and
3032 DeleteResultSetResponse. See include/proto.h.
3034 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3035 and added member 'languages' in TargetInfo (which was missing).
3037 Changed the way attribute sets are handled in the retrieval
3038 module. These are now cached, just like the abstract syntaxes
3041 Changed YAZ so that it links with compiled ASN.1.
3043 Added Explain-schema definitions and mapping routines. The following
3044 Explain categories have been implemented: AttributeDetails,
3045 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3047 Fixed minor bug in Windows version of Server Library.
3049 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3051 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3053 Added EXTERNAL: UNIverse Resource Report (non-standard).
3055 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3056 ENUMERATED and SET OF.
3058 * Added 'const' to some of the char pointer arguments for the
3059 functions, data1_read_node, data1_getelementbytagname,
3060 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3063 Fixed bug in data1_insert_taggeddata - the last_child member of
3064 parent wasn't initialised.
3066 * Changed data1_read_record and data1_read_node so that the supplied
3067 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3068 doesn't refer to any parts of the "SGML"-buffer.
3070 Fixed bug in server library (Windows version of statserv_remove).
3072 * Changed code so that it compiles as C++. The type definition
3073 of Odr_fun which is a member of Odr_arm was changed. The result is,
3074 that an explicit typecast is needed for the fun pointer when
3075 using Odr_arm - as in:
3076 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3078 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3080 Implemented the new structured date and time definition as approved
3081 by the ZIG. Added schemaId element to the specificTag in Espec-1
3082 (also approved at the last ZIG). Thanks to RVDM.
3084 Added some Object identifiers (RVDM).
3086 Changed the Update Extended Service (RVDM).
3088 Added command "refid" to client which specifies referenceId for
3089 the following requests.
3091 Implemented extended service handling for server. See ztest.c
3092 for an example as well as backend.h. New handlers are registerd
3093 in the Init handler.
3095 * Changed interface for sort in server.
3097 Added new members to statserv_options_block. It allows a server
3098 to read options from another source than just the command line. Thanks
3099 to Charles Woodfield.
3101 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3102 renamed to zboolean. Some C++ compilers complained about the name.
3104 Minor changes to gils.abs. Added index 's' (sort) on title
3105 and date/time-last-modified.
3107 --- 1.4pl2 1998/1/30
3109 Fixed bug in server library regarding inetd mode (-i). This bug
3110 was introduced by release 1.4.
3112 --- 1.4pl1 1998/1/29
3114 Added sort facility in client and backend server interface.
3116 Fixed problem with dependencies in Makefile(s).
3118 Fixed bugs for encoders/decoders of extended services and
3121 Implemented sub-tree feature for schemas. Sub-trees are
3122 referenced in *.abs-files. See explain.abs for an example
3123 of the use of this feature.
3125 Modified bib1.att; local attributes for ANY didn't include
3126 ANY itself (only affects use of the retrieval module).
3128 Fixed bug in plain SGML reader in function data1_read_node:
3129 tags with prefix "var" was incorrectly interpreted as variants.
3131 Added feature "sub-schemas" to enable references to - and definitions
3132 of - group of elements.
3134 * Removed member parent from type data1_element (in data1.h).
3136 Implemented function odr_nullval() that returns the value of
3139 * Removed member num_children from data1_node (in data1.h).
3141 Made NT service interface part of the server library. The
3142 function statserv_main uses the NT service when required and
3143 calls the statserv_start / statserv_close routines.
3145 Routine zget_SearchRequest and zget_PresentRequest fills
3146 resultSetName/Id member with "default" instead of "Default".
3148 Fixed memory leak in server. Request queue member wasn't freed.
3150 Fixed nmem_exit so that memory is freed.
3154 Revised the CCL parser utility to be thread safe.
3156 Added function, oid_ent_to_oid, to replace the function
3157 oid_getoidbyent, which is not thread safe.
3159 * Added nmem_init and nmem_exit to initialize and release
3160 NMEM resources. Function nmem_init should be called once in the
3161 initial thread before NMEM/ODR is used. statserv.c and client.c
3162 have been changed accordingly. The change was necessary to make
3163 NMEM thread safe. The NMEM memory pool is shared amongst threads
3164 in a process. Unix-based applications will still work fine without
3167 Added NT Services interface for the the Z39.50 (statserv) Server.
3168 Refer to the ztest.c source on the usage.
3170 Windows 95/NT port using MSVC5.0. Project files are included in the
3173 * Defined new 'global' handle for the retrieval (data1) system. The
3174 new handled, data1_handle, describes the state of the data1 system.
3175 This handle is passed as first argument to virtually all
3176 data1 related routines. The functions data1_create and data1_destroy
3177 creates and destroys a data1 handle respectively.
3179 Added ODR encode stream member to all backend request structures
3180 init, search, scan etc. This stream should be used to allocate all
3181 memory used for the response when thread safe operation is needed.
3183 Changed the comstack utility, cs_addstr, to be thread safe. The
3184 returned hostname string returned by the function is now part the
3187 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3188 function. The cs_straddr takes a COMSTACK handle as argument, so this
3189 function must be used after cs_create and before bind/connect.
3190 This function is thread safe.
3192 Moved test server to 'ztest' directory - generic server code still
3193 in 'server' directory.
3195 Made prefix query (pquery.c) utility thread safe.
3197 Added new function modifier YAZ_EXPORT to 'export' public DLL
3198 functions when using windows (see include/yconfig.h).
3200 Added definitions to the OID database (util/oid.c) (RVDM).
3202 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3204 Added call to ccl_rpn_delete in client program.
3206 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3207 release of RPN structure.
3209 Added support for C++, headers uses extern "C" for public definitions.
3210 With input from RVDM.
3212 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3213 Thanks to Ronald van der Meer (RVDM).
3215 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3217 Added support for private extensions to the OID database
3218 (oid_setprivateoids()). Thanks to RVDM.
3220 Added optional, physical ANY (key replication)
3222 Fixed null-reference problem in GRS-1 output filter.
3224 Proximity operator added to Prefix Query Format (PQF).
3226 In test client command "base" accepts multiple databases.
3228 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3232 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3234 Smallish bug-fixes in the new encoders/decoders (explain).
3236 Bug fixed in DeleteRequest.
3238 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3240 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3242 Added SOIF syntax (using private OID for now) to retrieval module and client.
3244 Added Update extended service.
3246 Added SearchResult-1 additional info structure.
3248 Added optional CCL (ISO8777) interpreter as separate module. Available
3251 --- 1.2 1996/6/10 (1st anniversary release)
3253 Added Summary record syntax. Lightly tested.
3255 Added OPAC record syntax. Untested.
3257 Added ResourceReport service encoders/decoders. Untested.
3259 Fixed bug in z_Unit - wrong tagging on unitSystem.
3261 Fixed bug in the DiagRecs decoder.
3263 Added options for max PDU size and session timeout to frontend-server.
3265 Added documentation of query-language parsers and other supporting utilities.
3267 [frontend-server] Added Attribute set to the bend_scanrequest API.
3269 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3270 surrogate diagnostics were generated.
3272 [retrieval] Allow multiple local values for attribute.
3274 [retrieval] Allow multiple attributes per element in .abs files. index type.
3276 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3278 --- 1.1pl2 1996/4/10
3280 Minor changes, mostly specific to Zebra's requirements (retrieval)
3284 Repaired bug in frontend server when running multiple listening
3285 endpoints in dynamic mode.
3287 z_External() now won't break if a known, ASN.1 value comes encapsulated
3288 in an octet-string. The value will pass through unmodified in an Odr_oct.
3290 Added a bit of code to the demo client to decode & display
3291 ASN.1-structured records represented in the octet-aligned branch of
3292 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3294 Added z_ext_getentbyref() to the ASN module. Doc updated.
3296 * Completed the SCAN definition in the ASN module. This may break SCAN
3297 code based on older YAZ-versions at compile-time. The fix is easy -
3300 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3301 under the SCAN definition. Remember to initialize this, server-people.
3303 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3304 that this does not extend to ODR and ASN.
3306 Comstack allows insertion of established socket (primarily for
3307 inetd-operation of servers). Doc updated.
3309 Front-end server can now start from the inetd in TCP mode. Doc
3312 --- 1.0pl4 1996/1/24
3316 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3317 the rank and record number.
3319 Adjustments to the frontend server.
3321 Fixed diagnostic BER dumper. It ignored the file argument.
3325 Various changes to retrieval module.
3327 Changed the union discriminators of the protocol files from enums to
3328 ints paired with #defines.
3330 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3333 *Changed operator in the RPN structure to 'roperator', again to avoid a
3336 Fixed problems in Explain decoders/encoders.
3338 --- 1.0pl2 1995/12/6
3340 Memory bug in log module fixed.
3342 --- 1.0pl1 1995/12/5
3344 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3346 Bug in Explain DatabaseInfo module fixed.
3348 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3352 The shift to v1.0 signals that we now consider the *core* functionality
3353 of YAZ reasonably stable (the core being more or less equivalent to
3354 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3355 tested (Explain not at all - though that will happen soonish).
3357 Minor changes to code to support Windows port.
3359 Various minor changes after we're getting to use GRS-1 & co. more.
3361 Added Espec-1 format.
3363 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3364 of the protocol and it cannot be selected when encoding (maps into 'string'
3365 when decoding). Needed to talk to some servers.
3367 Demo client can request simple element set names.
3369 Added Diagnostic Format encoders/decoders.
3371 Added simple Close handling to frontend server (no hooks for resource
3372 reporting yet), and demonstration client.
3374 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3376 --- 1.0b3 1995/08/24
3378 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3379 handled incorrectly when records were requested in the searchResponse. This
3380 will only affect you if you use the frontend-server.
3382 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3383 Test-client will ask for and print GRS1. Ztest will return dummy records
3386 Added Explain encoders/decoders to the service-level API. Untested.
3388 Added Extended Services: Item Order encoders and decoders to the Service-
3389 level API. Untested. We could use a recent copy of the pertinent bits
3390 of the ILL protocol to add those bits.
3392 Added diagnostic format 1 encoders/decoders to the service-level API.
3395 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3396 odr_cons.c, which causes a more correct output.
3398 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3399 was always set to 0 when no records were requested in the searchRequest.
3401 * Added better external-handling. This shouldn't harm old code that
3402 *encodes* externals. It can break code that looks for a
3403 'single-ASN1-type' representation, since those types that are known
3404 are now decoded immediately. Look at the SUTRS sample code in
3405 seshigh.c and client.c. Documentation updated.
3407 Handling of structured records in bend_fetchresponse. Length -1 marks
3408 structured record, type is deduced from format field.
3410 --- 1.0b2 1995/06/27
3411 Fairly quick maintenance release to add SUTRS support.
3413 Fixed handling of SUTRS records in the demonstration client.
3415 * Added format field to the bend_fetchrequest and bend_fetchresponce
3416 structures of the backend API (frontend server). When the record is
3417 returned, the value of the format field is mapped to an OID. The
3418 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3419 of the record. The special value VAL_NONE in the bend_request means
3420 that no specific format was requested by the client. Documentation
3421 updated accordingly. Test server (ztest) will return a fixed dummy
3422 SUTRS record if your client requests SUTRS.
3424 Documentation updated accordingly.
3426 You can now set external libraries and RANLIB support in the top-level
3430 First public release.
