3 ICU: New conversion element 'join' which joins tokens into one
4 with a custom character given by rule attribute.
8 New GFS search member: present_number. This is a hint to the
9 search handler how many records are going to be fetched immediately
10 following search. There's no guarantee that it's going to be the case,
11 since it depends on hit count (for Z39.50 piggyback) and whether errors
14 Make a few functions static (private). The functions getbyte_stream,
15 ungetbyte_stream and yaz_gets are now private. They were never declared
18 yaz-marcdump: exit(5) for serious decoding errors
20 ISO2709 decoding: be more picky WRT header
22 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
23 was only used as to indicate that next-result-set-position should be
25 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
26 Based on patch from Ashley Sanders.
28 Make some functions static/private in PQF parsing. Those functions were
29 never declared in a public header and so should not be in use by
30 applications based on YAZ.
34 ZOOM: special options to control APDU logging.
35 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
36 logging of APDUs until "saveAPDU" option is set again. If logging is
37 already enabled the effect is that current APDU buffer is cleared.
38 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
39 logging (default behavior on new connection).
40 The APDUs sent/received can be obtained by using
41 Using ZOOM_connection_option_get(c, "APDU") or
42 ZOOM_connection_option_getl(c, "APDU", &l).
44 GFS: relay implementation_version from backend
45 From 3.0.40 and later, implementation_version from backend was
46 not used in init response at all.
50 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
51 mode at all. Probably never did.
53 Make a new version of ztest.pem that, at least, is not expired.
57 Fix description of CCL directive 'case'.
59 More tight checking of form arguments (yaz_uri_to_array). Makes
60 YAZ better at rejecting big and/or bad POSTs.
62 SRU decoding does not report more than up to 10 invalid arguments.
64 rpn2cql: less quotes in generated terms. Semantics unchanged, but
65 it's prettier this way.
69 New utility yaz_decode_init_diag. Defined in proto.h.
71 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
72 given for unix local socket.
73 The COMSTACK string for doing so is:
76 unix:/myfile:tcp:localhost:9999/mybase
77 unix:/myfile:localhost:9999/mybase
78 unix:/myfile:http://fakehost/mybase
80 debian: Use dpkg-buildflags in build process.
84 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
85 global's SRU service uses a recordPosition scheme starting from zero.
86 First record's position should be one
87 according to the standard.
91 Allow more namespaces for SRU. This is to allow, for example, an
92 incorrect namespace returned from server
93 http://services.igi-global.com/sru .
95 Minor fixes for compilation on Windows.
99 daemon: log total number of bad signals from child on stop so that it
100 is more easy to spot problems with child worker processes.
102 retrieval: empty backend name attribute omits element set
103 from being used in retrieval.
105 --- 4.2.40 2012/10/04
107 Implement Solr sort strategy "solr", similar to sru11 sorting.
108 This will implement the correct parameters on Solr requst to do
111 --- 4.2.39 2012/09/28
113 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
116 MARC: Extra/missing indicator handled for MARCXML.
117 The indicator length is given in header and is the same for the
118 whole record. If attributes ind1, ind2 are missing, then content
119 character defaults to blank. Extra indicator attributes (beyond)
120 indicator length are treated as an error.
122 Reformat: delete trailing whitespace
124 --- 4.2.38 2012/09/17
126 MARC: fix non-ASCII characters for leader. This is to ensure we can
127 generate XML in UTF-8.
129 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
130 in one node with structure word.
132 --- 4.2.37 2012/09/04
134 yaz-json-parse: JSON output may be pretty printed by using option
137 Increase default value of max message for Z39.50 Init for GFS, ZOOM
138 and yaz-client. Old value was 1 MB. New value is 64 MB.
140 --- 4.2.36 2012/08/22
142 yaz-client: don't display bogus records from SRU servers. Some SRU servers
143 return more records than given by *maximumRecords*. Skipping those in
146 record_render: simplify buffer return handling and fix at least one bad
147 memory reference, that broke the test_embed_record sometimes.
149 Allow http://user:pass@host notation for yaz_url_exec.
151 zoomsh: allow shell command to be executed. Via the system(3) call.
153 yaz_poll: Allow num_fds == 0
155 yaz-client: fix bad encoding of "itemorder item". The itemorder
156 item <no> - command forgot to use length of encoded Item Request
157 package. Error present since YAZ 3.
159 yaz-ztest: fix bad usage of session handle. Bug was introduced when
160 result sets were saved (271a9c83).
162 SRU recordPacking: guess record packing in response rather than looking
163 at the recordPacking element which, OF COURSE, changed semantics in SRU
166 Decode SRU 2.0 responses. The official namespace for responses, according
167 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
168 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
169 nature.com's server, however, usee namespace
170 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
171 we are now using a glob-expr to match up the namespace. ZOOM C and
172 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
173 I can not find a single real example showing the "real" namespace in
174 the documentation from OASIS. The namespace for requests is different
175 from responses, but this is not added to YAZ yet, when we don't encode
178 --- 4.2.35 2012/06/26
180 zoom/record_render: add support for Base64 decoding fo MARC records
181 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
182 which will decode base64 + ISO2709 marc-8 encoded material from text node
185 --- 4.2.34 2012/06/07
187 Add missing definitions ZOOM_resultset_get_facet_field_by_index
188 and ZOOM_resultset_facets_names.
190 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
193 Change APDU dump printing to avoid long leading blanks. For levels 16
194 or larger the level is shown and the indentation is truncated but
195 recursed with modula 8. This makes it still reasonable easy to read
196 - even for nested BER dumps.
198 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
199 return 0 (incomplete package) in case where the BER package was
200 considered too nested (return value of -2).
202 dumpber: lines of level 15 are not indented further. Two spaces per
203 indentation; indentation 15 or more is indented to a fixed indentation
204 and augmented with a level=<no> indication.
206 zoomsh: increase max size of command+args
208 GFS: No limit in RPN buf size in CQL to RPN conversion.
210 --- 4.2.33 2012/05/09
212 New function for daemon utility, yaz_daemon_stop .
214 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
216 --- 4.2.32 2012/04/25
218 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
219 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
221 --- 4.2.31 2012/04/23
223 YAZ daemon utility relays SIGUSR1 to child process.
225 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
226 would result in en empty database list - which in turn would result in
227 encoding failure for search.
229 Fix reading beyond string in yaz_sort_spec.
231 --- 4.2.30 2012/04/11
233 Add two new SRU diagnostics:
234 236: Access to specified database denied
235 1015: Init/AC: Maximum number of simultaneous sessions for Userid
237 Document the very useful ZOOM-C option "apdulog".
239 CQL to RPN: term may be passed through verbatim. This is enabled with
240 truncation.cql . The assumption being that the term is already CQL.
242 --- 4.2.29 2012/03/20
244 record_conv: leader spec may be given for marc element.
245 The leader spec is given as attribute leaderspec for element marc.
246 For example to convert a MARC21 record from MARC-8 to UTF-8:
247 <marc inputformat="marc" outputformat="marc"
248 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
250 record_conv: allow user-XSLT params. For example:
251 <xslt stylesheet="MARC21slim2DC.xsl">
252 <param name="myparameter" value="myvalue"/>
253 <param name="otherparameter" value="othervalue"/>
256 record_conv: fix error handling for missing marc charsets.
258 CQL: fix extra terms in wrong order.
260 --- 4.2.28 2012/03/06
262 record_conv: modify new API for conversion types. The conversion types
263 may be passed in new functions yaz_record_conv_configure_t and
264 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
266 Avoid mixed statement/variable declare; fixes compilation with Visual
269 --- 4.2.27 2012/02/28
271 Add non-standard SRU diagnostic: 235: "Database does not exist".
272 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
273 Update SRU to Bib-1 diagnostic maps accordingly.
275 CCL: add two new diagnostics for unsupported masking. The new
276 diagnostics are: "Embedded truncation not supported" and
277 "Single charcacter mask not supported".
279 --- 4.2.26 2012/02/23
281 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
283 --- 4.2.25 2012/01/11
285 Build YAZ for Ubuntu Oneiric.
287 CCL: allow parantheses for proximity operands. For example CCL query
288 (a) % (b) is now allowed.
290 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
291 marked dead, rather then being destroyed. If not, the session memory is
292 being free'd before the search/scan handler is finished. Also destroy
293 'request' memory in request_release rather than in various places,
294 which resulted in leaks from time to time.
296 --- 4.2.24 2011/12/21
298 cql_sortby_to_sortkeys: honor sort prefix.
300 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
301 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
302 The rpn2cql family of functions now always returns quoted CQL terms.
304 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
306 --- 4.2.23 2011/12/15
308 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
309 sequence is treated as one. For example, &&a=b&&&c& is identical to
312 --- 4.2.22 2011/12/05
314 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
315 APDUs for a connection to a WRBUF.
317 --- 4.2.21 2011/11/23
319 Fix cql_sortby_to_sortkeys. Completely broken before.
321 Make CCL's @truncation work again.
323 --- 4.2.20 2011/11/09
325 New ZOOM connection setting: tproxy. It's like proxy, but does not
326 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
327 to set resolved address + port for a connection outside ZOOM itself.
329 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
331 --- 4.2.19 2011/11/07
333 Fix uninitialized variable in Solr spell support (could cause SEGV
334 for SRU response decoding).
336 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
337 back-end's addinfo through into the ZOOM response addinfo.
339 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
340 they are separated by a colon and a space rather than simply
343 --- 4.2.18 2011/10/28
345 Add support for Solr spell-checking/suggestions through ZOOM.
346 If a Solr target has been configured correctly for spelling-checking
347 and suggestions, these will now be returned on the ResultSet option
348 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
350 --- 4.2.17 2011/09/28
352 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
353 with a flag whether to substitute escape sequences or not.
355 --- 4.2.16 2011/09/22
357 Fix nmem_strsplit_escape to substitute escape char properly.
359 New option for zoomsh -e , which makes it abort on first error and
360 return process exit code to indicate success/failure.
362 YAZ options utility supports special option -- which makes all it treat
363 all following arguments as non-options.
365 --- 4.2.15 2011/09/16
367 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
368 searched if absolute filename is given.
370 Fix conv_xslt() error-reporting when stylesheet is not found.
371 (The value of fullpath is meaningless in this situation.)
373 --- 4.2.14 2011/09/07
375 Fix problem in CQL sort node creation: un-initialized memory.
377 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
378 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
379 CQL sortby depending on whether Type-1 or CQL is actually sent to the
382 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
383 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
385 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
386 will make it possible to use both single-character mask (#) and wildcard (?)
387 in CCL . Throw diagnostic for left truncation because that is not supported
390 --- 4.2.13 2011/09/01
392 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
393 cases using escapes (\-sequences) and masking.
395 PQF parse fix: A trailing backslash followed by end-of-string (\0)
396 would result in a read one byte beyond string.
398 rpn2ccl may use Z39.50 masking for terms (t=z).
400 ICU check fix. Don't include library -lCrun on Solaris, unless present.
402 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
403 not --cppflags (which seeems like an error in icu-config).
405 --- 4.2.12 2011/08/27 RPM package only
407 cql2ccl: fix conversion of terms: operator characters were not
410 --- 4.2.11 2011/08/25 RPM package only
412 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
413 CCL parser will map both # and ? to their regular expression
414 quivalents (. and .*).
416 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
417 of reserved CQL characters.
419 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
420 is, so that they are passed through.
422 --- 4.2.10 2011/08/24
424 ZOOM SRU mode: more aggressive re-connect.
426 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
427 made available as a utility function, declared in <yaz/logrpn.h>
429 rpn2cql_structure() supports proximity nodes (except that the Type-1
430 proximity node's "exclusion" binary is ignored, as there is no way to
431 express that in CQL). Fixes bug #4564.
435 Fix SEGV that could occur if set command of zoomsh was given without
436 value (2nd argument).
438 Fix SEGV that could occur if unsupported transport was given for
439 COMSTACK - say https (when SSL was unavailable).
441 Build yaz-url on Windows too.
445 New utility to get web content. Header is url.h. A command line tool
446 yaz-url is part of the distribution and packages.
448 Fixes for SSL COMSTACK (when gnutls is in use).
450 New functions yaz_base64{encode,decode}. Header is base64.h.
454 ZOOM C includes HTTP response buffer as additional info if it fails
455 to decode the SRU response.
457 Make wrbuf_json_puts available.
461 zoom: throw diagnostic for invalid value for option "sru". Before a
462 bad SRU request was sent.
464 Adding new utility wrbuf_vp_puts.
466 Add cclxmlconfig.obj to win/makefile. It was missing completely.
470 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
471 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
472 redirect was used at the same time.
474 MARC line mode decoding: be less picky about length given - first
475 5 digits of header that is.
477 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
479 Changes to decoding of SRU records: a record with recordPacking=xml is
480 modified with a new root element <yaz_record> if the recordData contains
481 multiple children elements. This is to make the record XML parseable
484 RPN to SOLR conversion: encode special characters.
486 Generic Frontend Server: fix uinitialized member, stepSize.
490 Fix a bug in SRU decoding of records.. The database records stored
491 had un-initialized memory, but it would only be seen with yaz_record_render
492 and type_spec="ext" .
494 Fix a bug in ccl_qual_dup introduced in 4.2.3.
498 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
502 Add new utilities to convert from CQL to CCL . These utilities have
503 prefix cql_to_ccl defined in cql.h.
505 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
506 lead to memory heap corruptions when ICU utilities were in use.
510 Make compilation work without Libxml2.
512 yaz-client: remove redundant blanks in display of searchResult-1 term
517 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
518 resulting CQL node (tree) in a new node CQL_NODE_SORT.
520 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
521 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
522 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
523 Note that the CQL sortby spec is only converted when the GFS is already
524 converting from CQL to RPN (cql2rpn element).
526 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
527 specify whether to collapse delimitors or not. The existing nmem_strsplit
528 do collapse (collapse parameter = 1).
530 Windows installer: For NSIS, set InstallDir depending on x86/x64.
532 Rename internal func yaz_use_attribute_create. While non-static, this
533 function is not declared in a public header.
537 Add -lCrun when linking with ICU on Solaris.
539 More quicks character set conversions for OPAC records.
543 fix problem with record_render: records were converted (character set
544 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
548 SRU: add methods for handling DADS SRU-proxy facets.
550 Separate OPAC record character set for ZOOM_record. yaz_record_render
551 allows a character set given as charset=from/opacfrom,to where 'from' is
552 the character set of a bibliographic record, 'opacfrom' is character set
553 of OPAC record and 'to' is the target character set.
557 yaz-client: show may XML format records. Command show followed by 'format'
558 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
561 src/stemmer.c: Avoid using unnamed union. It is not supported by some
564 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
567 Update yaz.spec to operate on both SLES11 / Centos 5.5.
569 RPM: Release includes 'indexdata' name. Use indexdata in release name so
570 this package can be distinguished from other vendors.
572 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
573 as determined by configure
575 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
577 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
578 returns no error and no record, the present request is considered
579 partial (only a subset of the records could be returned by backend), and
580 so it is appropriate to set Present Status to partial-4.
584 Move yaz-config man pages to section 1.
586 More documentation about SOLR.
588 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
589 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
590 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
591 peers on some Linux systems. However, in general that does not work
592 so YAZ can not rely on that to work. Debian changed behavior in this
593 respect from Debian lenny to Debian squeeze (still testing as of Oct
595 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
597 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
601 Fix yaz-config output: echo_source not set correctly by configure.
605 SOLR WebService support for yaz-client and ZOOM.
607 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
609 --- 4.0.12 2010/08/17
611 Z39.50 facet support. Facet specifications are passed for search in
612 other-information with ASN.1 as defined in facet.asn and OID
613 .10.1000.81.5 . Facets are expressed as an Attribute list as known
614 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
615 3 is limit (number of entries to get in response). yaz-ztest returns
616 dummy facets if a client asks for them.
618 --- 4.0.11 2010/07/09
620 CCL fixes: bug 2895 and bug 3539.
622 GR1-display: add comma in display - was removed by mistake in
625 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
627 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
629 --- 4.0.10 2010/06/18
631 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
632 result set from a connection. The result set will be on its own
633 thereafter; no operations on it will perform retrievals from a target.
634 Only cached copies are returned.
636 ZOOM C:fix case for HTTP servers responding with Connection:close.
637 Ensure that if there is a current task it is resumed (like fetching
638 more records in a result set) . Bug #3484.
640 PQF parser: use odr_atoi for Odr_int (not atoi)
642 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
643 values that contain any non-digits are treated as string attributes
644 (previously decoding only checked for leading character ([0-9]). PQF
645 encoding: attribute string values are not surrounded by double-quotes.
649 New utility for managing threads - thread_create.h.
651 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
652 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
653 but YAZ' implementation do.
655 Fixes for yaz_cond-functions on Windows 7.
657 DLL export more symbols.
659 zoomsh: show record do NOT render opac.
661 Remove *.la files from Debian and RPM packages.
665 Debian package libyaz-dev depends on libgnutls-dev again (was
666 removed in YAZ 4.0.6, but due to Libtool it is still needed
667 even though yaz-config do not list libgnutls libs).
669 ZOOM: Use only one WRBUF for returning string results for
670 ZOOM_resultset. Reduces memory usage for ZOOM in general.
672 ZOOM: ZOOM_connection do not use a shared pointer to
673 ZOOM_resultset after ZOOM_resultset is destructed by
674 user. Reverts to YAZ 4.0.4 behavior.
678 record-conv: fix problem with at least one XSL conversion -
679 due to probably incorrect usage of XML XSL documents.
683 Fix yaz-config for static mode and the use of SSL (gnutls).
687 Forward decl timeval struct in mutex.h and gettimeofday.h.
689 yaz-config: fix 'static' mode linking.
693 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
694 are wrappers for pthreads or Windows. For Windows these are put in
695 a separate DLL: yaz_cond4.
697 libyaz.la (whole source) is compiled with thread. If thread support
698 is enabled enabled, all source of YAZ is compiled with treading support.
699 This allows core utilities such as yaz_log to use thread facilities.
700 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
701 thread utilities. This commit moves mutex utilities (mutex.c) from
702 libyaz_server.la to libyaz.la.
704 yaz-json-parse displays leading text until error.
708 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
709 patch from Giannis Kosmas.
711 SRU: no longer URL encode SRU database. The URL for an SRU server is
712 a URL and such is alreeady encoded - at least when given with leading
713 http:// or https://. This reverts behavior to YAZ 3.0.50.
715 Support for new MARC XML notation TurboMARC which like MARCXML is a
716 complete representation of MARC/ISO2709.. This one, however, is more
717 compact and allows for faster processing with XSLT. TurboMARC can be
718 used in the marcdisp.h API, from the yaz-marcdump utility and from
721 yaz-ztest can be configured - via the database - to perform certain
722 delays when it performs operations search, present and single record
723 fetch. This allows testers to make yaz-ztest act as a real or even slow
724 Z39.50 server. Refer to the yaz-ztest man pages for details.
728 wrbuf_destroy allows NULL WRBUF passed to it.
730 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
732 Add ZOOM_connection_close.
734 No fixed size buffers for ZOOM shell - bug #3257.
736 tstodr: make it work on s390 platform.
738 New icu iterator-functions. The new icu_iter-functions makes it possible
739 to use ICU chains from many threads.
741 yaz-client: better syntax check for show command.
745 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
748 New simple local-file XML include facility which allows file glob-patterns.
749 Refer to yaz/xml_include.h.
751 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
754 ZOOM_record_get supports new parameter "format" which makes it format XML
757 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
758 JSONText in ECMA-262) is JSONValue, not JSONObject.
762 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
763 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
765 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
766 POSIX/Unix builds .so with major version 4.
768 Remove old LOG_-defines from log.h. They have been obsolete and
769 undefined by default for the last 5 years.
771 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
773 GFS: Remove socket (int *fd) from search_rr handler. The socket
774 descriptor ptr is a facility that allowed a search handler to supply
775 a socket which would serve as a callback - when search was complete.
776 This facility has now been in use for years.
778 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
779 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
780 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
781 returns 'const char *' rather than 'char *. The returned string is
782 read-only and should not be modified by applications. COMSTACK cs_close is
783 now a void function - it no longer returns int. No applications check for
784 the value and the implementations has always returned 0.
786 ZOOM: use size_t for scan hit counts and str size. Functions
787 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
788 occ (hit count) and len (string length) are now of type size_t pointer
789 rather than int pointer. This is to be able to represent large hit counts
790 and to also just to use the proper type for string length (strlen result).
792 New JSON parser. Refer to include/yaz/json.h .
794 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
795 Used to be int in some cases. Many wrbuf_-functions used to return an int
796 indicating some length.. These return values were never used. And so they
799 ODR: odr_malloc, odr_total now takes size_t for size.
801 clone_z_type: fix leak; occurred for encoding failures.
803 --- 3.0.52 2009/12/03
805 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
806 bug was introduced in 3.0.51.
808 --- 3.0.51 2009/12/02
810 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
812 tcpip comstack: fix leak for getaddrinfo.
814 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
815 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
816 Decoding of SRU "path" database is performed by private function
817 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
818 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
820 yaz-client: honor base command for SRU. Change when database setting
821 is applied for SRU and ensure it is kept when a connection is reset.
822 Change also the way errors are displayed or SRU (decoding of packages).
824 --- 3.0.50 2009/11/02
826 Add support for extra request / response data for SRU codecs and GFS.
827 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
828 for extra data response buffer and length. For the GFS, both request
829 and response data (XML) is carried in extra_args and extra_response_data
830 for the search handler. Patch by Ko van der Sloot.
832 ZOOM: For queries that cannot be converted to the specified rpnCharset,
833 ZOOM now returns a diagnostic on the client-side ('invalid query' /
834 10010). This fixes bug #2113.
836 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
837 cmdfile included a 'quit' command that would result in a memory violation.
839 --- 3.0.49 2009/10/01
841 Make a number of functions defined in xmlquery.c static. These have
842 never been declared in a public header file (yaz/xmlquery.h) and was
843 made public by mistake.
845 Improve speed of character conversions (iconv utilities). This makes
846 conversions from MARC-8 faster.
848 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
849 unless type desired is "raw". This will prevent type "xml" from
850 returning ISO2709 .. Which obviously can not be XML parsed.
852 Fix memory leak in ZOOM that would occur if option apdulog was used
853 on a re-used connection.
855 Frontend server logs HTTP requests.
857 Frontend server now sends Z39.50 close when it times out (sesssion has
858 been idle for too long). Versions 2.0.30 and earlier also sent close.
859 But due to a mistake this was disabled in all versions after that, i.e.
860 the server would just close the socket immediately.
862 yaz-client emits a better message when receiving an unrecognised
863 userInformationField.
865 Skip zero-length subfields when decoding ISO2709. This rare case happens
866 if a record has two FS characters in a sequence. Without this patch
867 there would be a reference beyond char array in using_code_len fragments
870 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
872 --- 3.0.48 2009/08/28
874 The show command offered by the zoomsh command now takes a 3d optional
875 parameter type which is what is passed to ZOOM_record. If the type
876 argument is omitted, "render" is used.
878 RPN to CQL conv may use USE string attributes (bug #2978).
880 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
882 --- 3.0.47 2009/07/08
884 Function yaz_xml2query allows a diagnostic element in the PQF XML
885 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
886 code and additional info respectively.
888 The BER BOOLEAN is now the integral type Odr_bool which still happens
889 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
890 typedef'd to Odr_int. This is still an integral 'int', but it may be
891 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
892 ASN-1 compiler as well as programs has been updated to use the new types.
894 --- 3.0.46 2009/06/08
896 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
897 only the bibliographic record was rendered. For type=opac, an OPAC
898 record is only returned if it is present.
900 iconv: small fix for encoding of advancegreek.
902 yaz-client: avoid double display of SRU/SRW records (bug #2798).
904 yaz-client: option auto_reconnect=on really reconnects.
906 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
908 server: avoid null ptr ref for for yaz_poll errors.
910 build: fix RPM build for RHEL 5.3.
912 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
914 --- 3.0.45 2009/03/31
916 Fixed bug #2709: TCP connect returns Invalid argument.
918 Fixed compilation for mingw.
920 Honor charset for raw records (ZOOM_record_get).
922 Fixed use of errno for threaded mode that was seen on Solaris 10.
924 Fixed argument passing with blanks in value for Windows Service.
926 Disable YAZ' own log rotate by default (no 1 GB limit).
927 The variable l_max_size which specifies the log file limit is set to 0
928 (DISABLED): This is due to the fact that YAZ is most often deployed using
929 logrotate. Also YAZ can not perform log rotate because of unsufficient
930 permissions (setuid).
932 --- 3.0.44 2009/02/17
934 List supported encodings in man page for yaz-iconv.
936 Fixed missing SSL libs for --libs output
938 Re-established OID record syntax application-xml. Nobody should use it
939 but we don't want to change soname because of this symbol being absent.
941 --- 3.0.42 2009/02/02
943 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
945 Added member named_result_sets for init handler struct for the GFS. This
946 allows a server to disable named result sets.
948 Removed OID record syntax application-xml.
950 Added support for rule-based transliterator for ICU wrapper of YAZ.
952 Fixed bug #1902: yaz-icu XML output.
954 Make YAZ checks Emacs friendly.
956 BITSTRING value shows value. Bug #2346.
958 ISO2709 decoding: skip control characters from indicator data.
960 Omit sort key by default in yaz-icu's output.
962 Allow combined single char options (again) for YAZ' options function.
964 Utility yaz-marcdump got option to display YAZ version (-V).
966 Allow YAZ to use ICU 3.4.
968 Added new ICU test case which illustrates removal of diacritics.
970 --- 3.0.41 2008/12/29
972 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
974 --- 3.0.40 2008/12/29
976 For configure, using option --without-xml2 also disables Libxslt/Libexslt
979 Fixed bug #2352: yaz-marcdump crashes for certain record.
981 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
983 Added support for Danmarc2 to UTF-8 conversion.
985 Added support for ISO5426 to UTF-8 conversion.
987 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
988 implementation version.
990 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
992 --- 3.0.38 2008/11/10
994 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
995 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
997 ZOOM C now interprets databaseName option for ZOOM connection as path
1000 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1002 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1004 Dummy Libxml2 types no longer defined in headers of YAZ'.
1006 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1009 --- 3.0.36 2008/09/26
1011 Various ODR chapter fixes.
1013 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1015 Added missing source for Windows compilation, mutex.c.
1017 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1019 For SRU connections in ZOOM all records up to "count" are now fetched.
1021 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1022 in Windows due to bad error handling for Libxml2.
1024 Added facility for sending arbitrary records (ASN.1 any) using
1025 ZOOM C's Extended service update. Patch by Sam Reynolds.
1027 New options for ZOOM C's connection, logapdu which makes ZOOM log
1030 --- 3.0.34 2008/06/18
1032 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1034 --- 3.0.32 2008/06/12
1036 Fixed memory violation that could occur when decoding UTF-8. This bug
1037 was only present in 3.0.30 of YAZ.
1039 --- 3.0.30 2008/06/06
1041 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1042 GNU TLS is used by default (if found).
1044 yaz-ztest returns OPAC records if a client asks for OPAC.
1046 Improved speed of MARC-8 encoding.
1048 Added support for lossy and loss-less MARC-8 encoding.
1050 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1052 Added new Windows Service wrapper (sc).
1054 yaz-client's itemorder command may now send a file.
1056 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1058 Added new function yaz_log_xml_errors.
1060 Allow (but warn) unknown XML attributes in MARCXML parsing.
1062 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1064 The UTF-8 to MARC-8 conversion now uses a different set of characters
1065 for Greek symbols. Bug #2120.
1067 --- 3.0.26 2008/02/21
1069 Added yaz_daemon (daemon.h).
1071 Fixed bug #2068: pkg-config trouble
1073 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1075 --- 3.0.24 2008/01/28
1077 Document --with-xml2 option.
1079 Added OPAC XML XSD (etc/opacxml.xsd).
1081 Allow glob mask for name attribute in retrieval element for the
1082 generic frontend server's retrieval facility.
1084 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1085 except POLLIN/POLLOUT.
1087 Fixed error handling in cs_listen. Bug #2037.
1089 --- 3.0.22 2008/01/20
1091 Fixed version in yaz/yaz-version.h.
1093 Fixed bug #2027: Crash when closing connection.
1095 Changed configure so that ICU support is only enabled if only ICU
1096 and Libxml2 is available (because the ICU chain is XML based).
1098 --- 3.0.20 2008/01/15
1100 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1101 is built. Only this DLL depends on the ICU runtime.
1103 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1104 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1106 Changed license of CCL module to 'Revised BSD'. After consultation with
1107 remaining members of the original EUROPAGATE consortium, we are re-issuing
1108 the CCL module without a separate license. The software was developed by
1109 Index Data as part of a research project. The special license was included
1110 to help feed usage information back to the project consortium to support
1111 project evaluation. At this time, the project consortium has long-since
1112 disbanded, and the majority of the original principals have retired. At the
1113 same time, we have significantly modified the software during the following
1114 years, to the point where very practically no original code remains. To
1115 simplify re-use of the software, we have contacted those members of the
1116 consortium who could be reached, and agreed to re-issue the module as a
1117 proper part of the YAZ package.
1119 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1121 CQL closer to being version 1.2 compliant. CQL also allows free-form
1122 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1125 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1126 bug could make Extended services handling crash in the ZOOM layer. This
1127 bug was only present in YAZ 3.0.18.
1129 --- 3.0.18 2007/12/19
1131 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1134 yaz-marcdump reads and writes collection wrapped records.
1136 Handle OPAC for record conversion module.
1138 Fixes for ICU wrapper.
1140 Allow ICU libs to be controlled with --with-icu .
1142 --- 3.0.16 2007/11/12
1144 Added yaz_poll which is a wrapper for select/poll. When poll is available
1145 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1146 sockets to be in use.
1148 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1149 functionality through an XML based configuration (ICU chain). This system
1150 is useful for search facilities such as Pazpar2 and Zebra that needs to
1151 perform tokenization of indexed material. The ICU code in a separate
1152 library libyaz3_icu.a.
1154 Added HTTP tunnel facility for COMSTACK, bug #1752.
1155 This is a facility that allows a Web proxy, such as squid, to tunnel
1156 Z39.50 traffic. This facility is "transparent" to must applications
1157 using YAZ. It's enabled by using pseudo transport connect: followed by
1158 the proxy address, followed by command, then follwed by he regular
1159 "virtual" addresss. For example,
1160 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1162 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1164 --- 3.0.14 2007/09/21
1166 Fixed bad memory reference in ZOOM_record - cuased by member not being
1167 initialized. This was a problem only in YAZ 3.0.12.
1169 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1170 fields were not removed.
1172 Changed the way C code is generated from codetables.xml. Made a MARC-8
1173 conversion trie for each characterSet section rather than codeTable.
1174 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1175 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1177 --- 3.0.12 2007/09/12
1179 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1180 from ZOOM_record_error).
1182 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1184 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1186 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1188 Better SRW-to-Bib-1 diagnostic mapping.
1190 ZOOM C and yaz-client announces SRU version 1.2 by default.
1192 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1195 Fixed in yaz_sru_decode to allow other version than 1.1.
1197 --- 3.0.10 2007/08/22
1199 Added support for SRU scan for ZOOM.
1201 Added support for the use of the older versions or Extended Service
1202 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1203 set to the version , 1=first, 2=second, 3=third. The third version is
1204 what ZOOM C has used so far. And that, obviously, is the default.
1206 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1207 therefore in Zebra and in SimpleServer-based applications). The new
1208 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1209 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1210 which is passed into the back-end search callback function.
1212 Added support for HTTP Basic authentication in clients: the SRU/W
1213 codec encodes the username/password elements of the PDU structure
1214 appropriately, and these may be set using the "user" and "password"
1215 options in ZOOM-C applications (the same options that are used for
1216 Z39.50 authentication).
1218 --- 3.0.8 2007/06/25
1220 Fixed bug #1208: SSL appears to be broken in ZOOM.
1222 Fixed bug #1206: Libxml2 include path weirdness.
1224 Added oid_name_to_dotstring.
1226 Allow elementSetName to be specified for ZOOM C record update.
1228 Allow waitAction to be specified for ZOOM C based for Extended Services.
1230 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1231 syntax OID. Bug introduced in YAZ 3 series.
1233 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1235 --- 3.0.6 2007/06/06
1237 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1238 directory. yaz-client now reads commands from file given by option -f
1239 if specified; then tries to read .yazclientrc in current directory.
1240 Failing that, it reads .yazclientrc from user's home directory.
1242 Added support for correlationInfo Note and ID for Record Update via
1245 Added yaz-client command querycharset which specifies character set for
1246 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1247 (termListAndStartPoint).
1249 Charset ISO5428:1984 is an alias for ISO5428-1984.
1251 Implemented a way to perform scan in a result set using Z39.50. This
1252 is achieved by attaching the result set name in the characterInfo
1253 (type InternationalString) of OtherInformation in the Scan Request PDU.
1254 The result set is identified in the otherinformation by the new OID:
1255 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1256 This allows for scan in result set and faceted search . Zebra did some
1257 of this in the APT term using attribute type 8 and value being result
1258 set. Using the OtherInformation approach for this is cleaner and easier
1259 to work with in proxies and the like. This facility can be used in
1260 yaz-client using new command setscan which takes a result set as first
1261 argument, start position (APT) as second.
1263 Changed decoding of SRU XML packed records to deal with servers that
1264 have recordData with XML data with multiple root nodes. Also make
1265 comparison for recordPacking case insensitive. Again, one server
1266 returns "XML" where others return "xml".
1268 For SRU responses allow Content-Type application/xml as well as text/xml.
1270 --- 3.0.4 2007/05/21
1272 Fixed bug in character set conversion of BER strings. Bug introduced
1275 --- 3.0.2 2007/05/08
1277 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1279 For OID class, use oid_class consistently.
1281 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1284 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1285 character set for bibliographic information interchange". By Giannis Kosmas.
1287 Added documentation on new OID API.
1289 --- 3.0.0 2007/05/02
1291 Changes to generic frontend server interface: added new member
1292 'query_charset' for bend_initrequest structure. A backend init handler
1293 should set this member to its native character set for query terms.
1294 When defined, the frontend server logic will announce this character set
1295 to a client if the negotiationModel bit is set by the client. All server
1296 implementors are encouraged to specify this. If a backend server does not
1297 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1299 Added CCL utility to remove terms (stop words) from resulting RPN
1300 tree. This is handled by functions with prefix ccl_stop_words_ .
1302 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1303 terms in RPN queries.
1305 Clean-up the CCL API. Moved some internal structures from ccl.h to
1306 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1307 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1308 This is replaced by ccl_parser_find_str which takes a string instead.
1310 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1311 libyaz.la is the core of YAZ except the generic frontend server and
1312 does not depend on POSIX threads anymore. libyaz_server.la is the
1313 generic frontend server facilities and uses POSIX thread functionality
1314 if available. The libyaz.la no longer depends on POSIX threads because
1315 the number of global structures is limited. NMEM no longer re-uses blocks
1316 between threads ; it simply free's memory immediately but allocates in
1317 "large" chunks as usual. We don't expect any performance penalties
1318 because of this. The yaz_log system is still using a global log_level so
1319 caution must be taken when modifying it with yaz_log_init_.. +
1320 yaz_log_mask_str. This, however, should not cause any trouble because
1321 these functions are called during initialization of application code
1322 anyway. `yaz-config --libs server` returns libs for server applications;
1323 `yaz-config --libs` returns libs for non-server applications.
1325 New OID database - with public definitions in oid_db.h. Removed old OID
1326 database including the head oid.h and definitions such as enum oid_value
1327 and struct oident. The new OID database uses the same string names as
1328 before but the 'protocol' is gone. There are now only two representations
1329 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1330 converts from string to OID; functions with prefix yaz_oid_to_string
1331 converts the other way.
1333 Change to emit_term() in CQL-to-PQF query translation: when a term has
1334 the /regexp relation modifier, do not process it for leading and
1335 trailing "^" and "*", which have quite different meanings in regular
1338 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1339 write handlers no longer carries a 'last' parameter. This will make
1340 yaz_iconv flush "less" characters. A flush is performed by call to
1341 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1343 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1344 removed, because function yaz_query_to_wrbuf does the same.
1346 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1347 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1349 Deprecated MARC utility functions removed.
1351 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1354 Branch split: YAZ_2_1_55_branch
1356 --- 2.1.54 2007/03/16
1358 Fix to ZOOM-C so that transparent reconnection is properly handled on
1359 connections that are in asynchronous mode.
1361 Fixed compilation on OpenBSD 4.0.
1363 Large strings in GRS-1 records are now properly displayed in yaz-client.
1365 Added character conversion support for "advancegreek"; based on patch from
1368 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1369 sequence is met. Before the error was not set so it would be unknown.
1371 Adjust yaz-marcdump MARC reader so that it skips until record separator
1374 --- 2.1.52 2007/03/07
1376 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1377 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1378 fd_set structure used as a bitmask for the FDs to be selected on.
1380 Using ACX_PTHREAD macro to check for POSIX threads.
1382 Fixed have-vsnprintf check.
1384 --- 2.1.50 2007/02/23
1386 Fixes for configure on BSD. Bug #900.
1388 Added snprintf/vsnprintf wrappers for systems that don't have
1389 limits (heavens forbid).
1391 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1392 created before all previous tasks were completed and removed from the
1393 task queue, the new task could be removed by a mistake.
1395 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1397 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1399 Fixed bug #832: Problem with MARC/charset in yaz-client.
1401 Fixed bug #668: save command line history for yaz-client.
1403 Fixed bug #830: pkg-config support.
1405 --- 2.1.48 2007/01/23
1407 Extended ZOOM result set options with two options that may be read by
1408 a client: resultSetStatus and presentStatus with values as specified for
1410 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1412 Fixed bug #827: Using SSL fails on Debian etch.
1414 Fixed bug #826: Weird looking chars for set of MARC records.
1416 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1417 that is treated as an ItemOrder with itemRequest being an XML document
1418 external. The value of "doc" is the content.
1420 Extended the GFS search facility. New member of bend_search_rr
1421 'estimated_hit_count' signals that hits is known to be an estmate
1422 (higher or lower than real hit count). New member 'partial_resultset'
1423 signals that the search was partial (hit count is lower or equal than
1424 real hit count). For Z39.50, the information is stored in resultSetStatus
1425 member of SearchResponse APDU. For SRU, the information is signalled
1426 via SRU diagnostic 59: "Result set created with valid partial results
1429 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1431 --- 2.1.46 2007/01/13
1433 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1435 Added ZOOM_connection_peek_event.
1437 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1438 the following new functions:
1439 ZOOM_event_nonblock, ZOOM_connection_process,
1440 ZOOM_connection_get_{socket,mask,timeout},
1441 ZOOM_connection_fire_event_{timeout,socket}.
1442 The existing blocking event handler, ZOOM_event, is a wrapper for the
1443 + blocking ZOOM_event_sys_{poll,select}.
1445 Implemented function ccl_xml_config which parses XML version of CCL
1446 configuration (bug #798).
1448 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1450 Added timings utility (yaz/timing.h)
1452 --- 2.1.44 2007/01/03
1454 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1457 Fixed bug #779: Rotation of apdu.log fails.
1459 Fixed for character set conversions:
1460 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1461 Honor G1 set in MARC-8 decoding.
1463 --- 2.1.42 2006/12/17
1465 Fixed bug #775: char conversion does not handle Alternative UTF-8
1468 Implemented function yaz_marc_read_line which parses MARC line format
1469 records. There is a wealth of formats out there. So far, this function
1470 reads line records produced by yaz_marc_write_line.
1472 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1473 more generic and easier to remember(!) options: -i format and -o format
1474 which specifies input format and output format respectively - where
1475 format is one of "marc", "marcxml", "line", "marcxchange".
1477 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1478 does not print anything except warnings for records.
1480 For yaz-marcdump, added support for MARC split into files (-s) with a given
1483 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1484 spec, at http://www.loc.gov/standards/sru/record-update/
1485 This has changed the binary layout of the following structs:
1486 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1487 bend_update_rr . Patch by Ko van der Sloot.
1489 Added GFS utility function bend_assoc_is_alive which returns 1 if
1490 association is still alive (client is connected); 0 otherwise (client
1491 closed connection). This allows busy servers to stop working for
1494 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1495 been a separate piece of software. This version of ziffy has been modified
1496 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1498 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1500 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1501 Client code may now interrogate options such as "init_opt_sort" to
1502 find out whether the server claims to support various options.
1504 --- 2.1.40 2006/11/27
1506 Added utilities yaz_{set,get}_esn to set/get element set name from
1509 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1510 of YAZ and has been so since YAZ 2.1.10.
1512 Implemented ZOOM_record_error which returns error information for
1513 record (surrogate diagnostic).
1515 --- 2.1.38 2006/10/31
1517 Updates for SRU Update by Ko van der Sloot:
1518 1. Changed name from "operation" to "action"
1519 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1520 versions in the code, marked as 'backward compatible'.
1521 3. Added diagnostics for SRU Update.
1523 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1525 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1527 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1529 For GFS, fixed problem with SRU diagnostic 'First record position out of
1530 range' being issued for 0 hits.
1532 zoomtst10 part of Windows Build.
1534 --- 2.1.36 2006/10/13
1536 Implemented yaz_filepath_comp which splits a path into file path
1537 components (required by Zebra 2.0.3+).
1539 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1540 BSD inspired license until now so this should not have any real impact on
1541 anybody. See http://www.opensource.org/licenses/bsd-license.php
1543 Fixed bug #687: Missing log lines.
1545 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1548 Fixed bug #689: SRU diagnostics to be added.
1550 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1551 whether a connection is idle (no more work do do).
1553 --- 2.1.34 2006/10/04
1555 Change type of optval from long to int for invocation of setsockopt with
1556 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1558 Added support for specifying the max log file size for the Generic
1559 Frontend Server. The size is given with option -r.
1561 --- 2.1.32 2006/09/21
1563 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1565 --- 2.1.30 2006/09/17
1567 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1570 Fixed bug in Generic Frontend Server that could cause a server to stop
1571 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1573 For the generic frontend server, the maximum record size is used as maximum
1574 size of incoming packages (SRU + Z39.50). The value until was previously
1575 only used in Z39.50 Init negotiation and, later, in a session controlled
1576 sizes of records returned. This is controlled using -k option. It can be
1577 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1579 --- 2.1.28 2006/09/04
1581 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1584 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1586 New option for yaz-marcdump -lpos=value which allows setting a portion
1587 of MARC header to a certain value.
1589 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1591 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1592 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1594 --- 2.1.26 2006/08/15
1596 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1599 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1601 --- 2.1.24 2006/08/08
1603 Fixed MARC ISO2709 encoding routines to deal with character set
1606 Minor changes to GFS logging. Database included in search request log
1609 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1610 cached/multiple records.
1612 Shared libraries are built by default on Unix+configure.
1614 Changed cql2pqf transformation to use a different evaluation order. The
1615 new order is: always, relation, structure, position, truncation, index
1616 and relationModifier. Old order was: always, relation, relationModifier,
1617 structure, index, position, truncation. Note that the the latter ones
1618 override former ones for identical attributes.. The new scheme means that
1619 it is possible to override any existing attribute with a relationModifier.
1620 And also that it is possible to override everything for the index rule
1621 (except the ones listed in relationModifier). No order is perfect but this
1622 one, we believe, covers more real cases.. The "always" should have been
1623 called "default", since the attributes there can be overridden with all
1626 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1627 compilation phase, but also for yaz-config --cflags output. This allows
1628 us to have public headers with Libxml2 stuff in them . It should also,
1629 eventually, make Libxml2 checks redundant in packages using YAZ, such
1632 --- 2.1.22 2006/06/15
1634 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1635 stored in uri, message and details.. Previously diagnostics were stored
1636 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1637 compatibility.. but he's probably the only one affected, so.
1639 Added support for CCL, compiled on the client side, in ZOOM-C. This
1640 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1641 input; the resulting query objects can be used for for searching with
1642 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1644 YAZ' configure searches for OpenSSL by default.
1646 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1647 SL_CTX_use_certificate_file. See
1648 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1649 for more info. Thanks to Ko van der Sloot.
1651 --- 2.1.20 2006/06/02
1653 Bug #600: SRU GET, POST support for yaz-client. Introduced
1654 command 'sru' which selects method SOAP/GET/POST.
1656 Allow missingValueAction to be specified for the sortspec string -
1657 function yaz_sort_spec. By default, the missing value action is null.
1658 Use ! to specify "abort". Use = followed by stringvalue to specify default
1661 Ensured that Present-handler (if defined) is called in GFS before any call to
1662 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1663 searchRetrieve requests.
1665 Documentation for YAZ is now based on the Docbook XML/XSLT using
1666 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1667 is no longer depending on jade/openjade or docbook-to-man scripts.
1668 PDF is no longer part of the distribution - but can optionally be
1669 made using DSSSL/jadetex or FOP.
1671 Added retrieval handling support in Generic Frontend Server to support
1672 conversion between MARC/XML as well as XSLTtransforms. See
1673 etc/yazgfs.xml for an example.
1675 Added Authentication support to Generic Frontend Server in SRU
1676 mode. Authentication using HTTP Basic is supported, as is the use
1677 of 'x-username' and 'x-password' parameters in the request itself.
1679 Added support for a new character set MARC8s identical to MARC8 except
1680 that it converts combined characters to single Unicode characters in the
1681 Latin-1 range (when possible).
1683 --- 2.1.18 2006/04/24
1685 ASN.1 compiler 0.4: generates brief Doxygen file header for
1686 generated .h/.c files.
1688 Utility yaz_iconv now supports conversion to MARC-8.
1690 New facilities for the MARC module. The reading - and writing of
1691 content are separate methods for the yaz_marc_t handle. The following
1692 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1693 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1694 format). Write functions have prefix yaz_marc_write_.. The existing
1695 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1696 available. Removed support for OAI-MARC and simplexml (not the
1697 simplexml from PHP5).
1699 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1700 to be returned for this connection.
1702 --- 2.1.16 2006/03/31
1704 Allow multiple languages and charsets to be specified with
1705 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1706 negcharset iso-8859-1,utf-8
1708 Translation of proximity nodes from CQL into PQF now works.
1710 Moved to automake 1.8, 1.9.
1712 Added function yaz_log_set_handler which allows a log handler to be
1713 installed. This handler will be called for all log messages. Output
1714 to file is also produced; but that can be disabled by passing NULL
1715 fname to yaz_log_init_file.
1717 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1719 For SRW (including GFS), accept application/soap+xml as content-type
1722 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1723 produces NO stylesheet reference even if a default stylesheet is specified
1726 --- 2.1.14 2006/03/14
1728 Updated Windows package to include yazd.dll + yazd.lib for the
1729 Development component.
1731 If the environment variable YAZ_LOG is set, then it is used as a
1732 string indicating the default level of logging to use if not
1733 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1734 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1735 used as before. So, for example, to omit warnings from YAZ logging,
1736 export YAZ_LOG=-warn
1738 cql_transform() now map structure and other attributes before indexes,
1739 so that index-specific structures and other attributes can override
1740 defaults. So now a combination of mapping specifications such as:
1742 index.dc.date = 1=date-modified 4=5
1743 does the right thing.
1745 cql_transform() now also respects the "always" mapping specification,
1746 which establishes an initial set of attributes to be used for all
1747 terms except where overridden by more specific attributes associated
1748 with the index, relation or modifier.
1750 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1751 which mode to use; one of "post", "get" or "soap" (SRW, default).
1753 Fixes for yaz_iconv routines: changed trie-based character set conversions
1754 to use only non-negative values for bit fields due to Sun's C compiler not
1755 supporting negative values.
1757 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1758 sequences where not read correctly. Fix by Rustam Usmanov.
1760 Updated win/makefile to use options, settings which makes things
1761 compile with VS C 2005.
1763 --- 2.1.12 2006/02/01
1765 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1767 In ZOOM socket code, use select instead of poll on MacOSX.
1769 ZOOM-C now support client-side compilation of CQL into RPN that is
1770 sent to the server, enabling CQL to be used against all Z39.50
1771 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1772 ZOOM_query object, and submit it using ZOOM_connection_search().
1773 The CQL-to-RPN translation uses a configuration file, the name of
1774 which must be specified in the Connection's "cqlfile" option.
1776 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1777 function, which takes as its start-term parameter a ZOOM_query object
1778 (which may have had either CQL or RPN set into it).
1781 --- 2.1.10 2005/11/29
1783 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1784 GFS to support this as well. Backend handler, bend_srw_update, does the
1785 update work. Code contributed by Ko van der Sloot.
1787 Allow retrieval of Search Result-1 information in ZOOM by the use of
1788 options that are attached to a result set. ZOOM documentation updated
1791 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1792 UTF-8 conversion. Patch by Raj Patel.
1794 Added option -m to GFS to control formatting of timestamps in log file.
1796 Added 'exit' as synonym for 'quit' in yaz-client
1798 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1799 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1800 for the new members. Patch by Ko van der Sloot.
1802 Added support for SRU POST. It is supported for content-type
1803 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1805 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1806 Instead make the library libyaz.la multi-threaded. Threading as a whole
1807 can still be disabled by configure option --disable-threads. Previosly,
1808 with older GLIBCs there were problems with MT libs under Apache. This
1809 has now been fixed a long time ago.
1811 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1814 CQL module modified to be case insensitive for relations/indexes/operations.
1816 Fixed bug in CQL transform code: incorrect value relationModifieder
1819 Added 'show all' command for yaz-client which retrieves all results
1822 Added new yaz-client, xmles, which takes a (private) OID and
1823 a document to be sent as an extended service request.
1825 Describe new yaz-client commands wait_response and set_auto_wait.
1827 Increase TCP/IP listener backlog from 3 (which I am guessing was
1828 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1829 that the socket will queue as many incoming connections as it's able
1830 to handle ongoing connections. In other words, it will never now
1831 refuse a connection that it would be able to handle merely because
1832 it's not got around to accepting() enough of the pending connections
1833 yet. This is the behaviour anyway under Linux, where the listen()
1834 argument is ignored; but not under BSD and on systems such as
1835 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1836 YAZ-based servers should now be uniform across operating systems in
1839 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1840 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1841 This allows yaz-marcdump to read large MARC batches (>2 GB).
1843 Modified all YAZ source files - except the source which is auto-generated
1844 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1847 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1848 corresponding to the existing *_setl() function. These allow option
1849 values containing arbitrary valuues.
1851 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1852 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1853 except that it returns an indicator of whether or not the sort
1854 criterion was accepted (0 for OK, -1 for invalid).
1856 --- 2.1.8 2005/06/07
1858 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1859 MARC output rather than returning "new" buffer.
1861 yaz-client warns about unknown init options.
1863 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1865 --- 2.1.6 2005/05/24
1867 Added support for SRW sort in Generic Frontend Server. Patch
1868 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1869 sortKeys - or NULL if none is provided.
1871 Fixed bug #307: It was impossible to specify indefinite/no timeout
1872 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1875 Added support for multiple languages and charsets to be specified in
1876 ZOOM. Each charset/language is separated by a blank. If negotiation is
1877 in effect in init-response, Option
1878 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1879 Code based on patch by Vasiliy Osadchuk.
1881 Fixed bug #306: infinite recursion that occurred when calling
1882 yaz_log_level_init as the first call (before other log level or
1885 Fixed bug in scan handling in front end server: if preferred-Position-In-
1886 Response was non-present, a NULL pointer referece was performed.
1888 --- 2.1.4 2005/04/26
1890 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1891 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1892 now defined for all those error codes. So instead of putting 109 in
1893 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1894 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1896 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1899 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1901 Program yaz-client now exits and produces an error message if multiple
1902 Z39.50 servers are specified on the command line (none or one allowed
1905 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1908 --- 2.1.2 2005/03/16
1910 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1912 Fixed bug #272: Preserve spacing for CCL terms.
1914 --- 2.1.0 2005/03/14
1916 Added support for virtual hosts and multiple backend servers for
1917 the YAZ frontend server. The configution is XML based and
1918 support specificition of CQL to RPN mappings and explain information.
1919 See section "Virtual Hosts" in the YAZ manual.
1921 Extended OPAC display utility. OPAC display utility renders
1922 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1923 to supplement yaz_marc_decode_wrbuf.
1925 Fixed a bug in MARC decoder that could caused it to crash for some
1926 invalid MARC records. More diagnostics and warnings where added in
1927 XML output (warnings, etc are stored in comments).
1929 --- 2.0.34 2005/02/08
1931 Fixes for UNIX domain sockets. Bug #261.
1933 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1935 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1936 Added yaz_marc_subfield_str which defines subfield lead string which is
1937 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1938 yaz_marc_endline_str which defines end of fields string used in
1939 YAZ_MARC_LINE format. Default string is newline.
1941 Experimental support for MarcXChange. This format can be produced
1942 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1943 http://www.bs.dk/standards/MarcXchange.xsd
1945 Added yaz-client commands scansize that sets maximum number of
1946 entries to be returned by scan.
1948 --- 2.0.32 2005/01/11
1950 Added support for SRW scan in yaz-client and Generic Frontend Server.
1952 * Added whereInList member to SRW Scan Term.
1954 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1956 Fixed NMEM system to return aligned blocks on the smallest boundaries
1957 that are suitably aligned for all possible types on the particular
1958 architecture YAZ is being built for.
1960 --- 2.0.30 2005/01/04
1962 Fixed numerious warnings that was issued with newer versions of GCC.
1964 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1965 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1968 Make YAZ Generic Frontend Server slightly faster.
1970 Enhance (and reduce) logging for Generic Frontend Server.
1972 Revert YAZ log system so that it flushes every write operation
1973 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1975 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1976 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1977 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1978 will effectively disable old definitions.
1980 --- 2.0.28 2004/11/09
1982 Added yaz_log_time_format which specifies log format using
1985 Added yaz_log_module_level which returns mask for a module. Value
1986 is non-zero mask a if module is enabled; zero if disabled.
1988 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1989 in include/yaz/cql.h.
1991 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1993 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1995 Fixed bug #172: RPM builds does not enable SSL.
1997 Doxyfile.in part of dist. Doxyfile generated by configure.
1999 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2000 are given and the corresponding component does not exist.
2002 Extend CCL documentation in YAZ reference. Describe r=r.
2004 --- 2.0.26 2004/10/01
2006 Fixed MARC->MARCXML conversion to properly deal with
2007 fields, subfields, indicators having non-ASCII characters.
2009 Fixed MARC->MARCXML conversion so that ASCII control characters
2010 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2013 Added YAZ GFS support for conversion from Z39.50 surrogate
2014 diagnostics to SRW surrogate diagnostics.
2016 Bug fix: YAZ GFS did not return schema in explainResponse.
2018 --- 2.0.25 2004/09/30
2020 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2021 now converts recordSchema to elementSetName as well as schema URI.
2023 Fixed bug in COMSTACK that prevented HTTP request packages from being
2026 --- 2.0.24 2004/09/29
2028 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2029 does not require white-space before and after the dash in a range, e.g.
2030 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2033 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2034 due to new GCC removing "redundant" code.
2036 Added yaz-client commands scanpos and scanstep that sets preferred
2037 position and step-size for scan.
2039 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2041 Added CCL utility ccl_qual_buf which parses one or more CCL
2042 spec lines in a buffer.
2044 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2045 of name and value - ignoring empty lines and comments.
2047 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2049 Added odr_get_element_path which returns current element path for an
2050 ODR handle. This utility is useful in error handling or user-defined
2053 Added ODR_PRINT utility odr_set_stream which is is a more generic
2054 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2055 to a write function and pointer to close function. The close function - if
2056 non-NULL - will be called during odr_destroy.
2058 Fixed bug in CCL parser where truncation char was not removed from
2059 right side when truncation=both was in effect.
2061 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2064 --- 2.0.23 2004/08/11
2066 Fix buffer overrun in CQL parser when dealing with proximity (%).
2068 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2069 to UTF-8/UCS conversion is now only based on codetables.xml.
2071 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2073 --- 2.0.22 2004/08/06
2075 Add support for more "commit changes" in ZOOM (uses Extended Services).
2077 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2080 Yet another small fix for configure of SSL.
2082 --- 2.0.21 2004/05/14
2084 Fix SSL libs for configure when --with-openssl=DIR is given.
2086 --- 2.0.20 2004/05/10
2088 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2090 SSL comstack now uses yaz.pem certificate file on server side
2091 by default. Certificate filename can be configured by calling
2092 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2094 Fix bug regarding multiple calls to ZOOM_connection_connect.
2096 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2098 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2099 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2101 ZOOM now allows inspection of X509 peer certificate for verification.
2102 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2104 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2105 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2106 as "modular" but it simplifies things.
2108 Added cs_get_peer_certificate to that returns peer X509 PEM.
2110 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2111 NULL if SSL is unavailable.
2113 Documentation about MARC decoding tools.
2115 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2117 --- 2.0.19 2004/03/30
2119 Rename CHANGELOG to NEWS to follow GNU style packing.
2121 Fix bug with missing initialization of member in init_diagnostics.
2122 This bug affects threaded version of GFS server.
2124 --- 2.0.18 2004/03/20
2126 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2129 Ensure zlib.dll is packed with Windows install.
2131 --- 2.0.17 2004/03/17
2133 Fix encoding of xsd:string to use text instead of CDATA.
2135 Fix endless loop in CQL parser with unbalanced ".
2137 Use a more compact way to store MARC-8 conversion tables.
2139 --- 2.0.16 2004/03/16 Debian only
2141 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2144 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2149 --- 2.0.15 2004/03/01
2151 Another fix for decoding of XML packed records.
2153 --- 2.0.14 2004/02/25
2155 Fixes for Chunked encoding. White space not ignored after length spec.
2157 Update NS and use default NS for SRW diagnostic elements.
2159 --- 2.0.13 2004/02/23
2161 Implement ZOOM_resultset_cache_reset which resets record cache.
2163 Implement ZOOM_resultset_sort which sorts a result set.
2165 Implement chunked HTTP transfer.
2167 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2169 --- 2.0.12 2004/02/16
2171 Added member 'schema' to bend_explain_rr structure so that backend
2172 can specify explain record identifier. Defaults to Zeerex 2.0.
2174 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2176 --- 2.0.11 2004/02/16
2178 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2181 Added init command for yaz-client which sends "extra" init request.
2183 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2184 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2186 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2188 Make ZOOM error code for "invalid query".
2190 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2192 --- 2.0.10 2004/02/05
2194 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2197 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2199 Added option -p <file> to make Generic Frontend Server to write PID file.
2201 Added option -D to put Generic Frontend Server in background on its own.
2203 Make ZOOM C recognize option "password". If unset, "pass" is used
2204 (for backwards compatibility).
2206 Fixed a bug in Generic Frontend Server that could make it crash if a
2207 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2210 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2211 Must be issued before open, in order to be in effect.
2213 --- 2.0.9-6 2004/01/12 Debian/Windows
2215 Make the SRU server more picky WRT unknown params, etc.
2217 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2219 New YAZ client command, options, that sets Z39.50 options.
2221 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2222 options from a string of tokens (one token for each option bit).
2224 Update SRW diagnostic code messages.
2226 --- 2.0.9-5 2004/01/07 Debian/Windows
2228 Handle user defined stylesheet for SRW/SRU.
2230 --- 2.0.9-4 2004/01/06 Debian/Windows
2232 Fix bug in decoding of Content-Length.
2234 --- 2.0.9-3 2004/01/06 Debian/Windows
2236 Fix a bug with decoding of XML packed records.
2238 --- 2.0.9-2 2004/01/05 Debian only
2240 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2242 Fix bug in SRW/SRU diagnostics decoding.
2244 --- 2.0.9 2004/01/05
2246 Fixed bug in Generic Frontend Server which could drop records exceeding
2247 preferred message size. Reported and fixed by Irina Dijour.
2249 Fixed calculation of package size for structured records in Generic
2250 Frontend Server. Reported and fixed by Irina Dijour.
2252 Fixed namespace for SRW/SRU diagnostics.
2254 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2256 --- 2.0.8 2003/12/22
2258 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2259 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2262 CQL changes to reflect recent changes to the specification:
2263 * Documentation talks about context sets instead of index sets.
2264 * Documentation talks about indexes instead of qualifiers.
2265 * The CQL-to-PQF transformer's configuration file now uses
2266 "index.set.name = <attributes>" instead of the old form
2267 "qualifier.set.name = <attributes>". (Both forms are still
2268 understood but the latter is deprecated.)
2269 * CQL terms with no explicit index specified are now interpreted as
2270 cql.serverChoice instead of srw.serverChoice (which of course
2271 behaves exactly the same.)
2273 --- 2.0.7 2003/12/16
2275 MARC conversion can now generate ISO2709 output in another
2276 character set. yaz-marcdump uses this facility if you invoke it
2279 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2280 functions from there can be used from C++.
2282 --- 2.0.6 2003/12/04
2284 Frontend server now transfers memory from decoded packages to stream
2287 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2288 references to show up.
2290 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2291 the ZOOM Abstract API. The older names for the same options are still
2292 also supported for the benefit of old applications.
2294 ZOOM-C supports "implementationId" and "implementationVersion" options
2295 to go along with "implementationName". These allow the user code to
2296 specify identification strings to be sent to servers.
2297 Add OID for the new ExtLite attribute set.
2299 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2300 as requested/supplid by Ere Maijala <ere@atp.fi>
2302 For generic frontend server, reverse the order of
2303 "toolkit-supplied / application-supplied" strings sent as implementationId,
2304 Name and Version. Also, remove the spaces around the slash. This brings
2305 the GFS in line with the behaviour of ZOOM-C on the client side.
2307 Add function ZOOM_scanset_display_term.
2309 yaz-client shows scan displayTerm if present.
2311 Utility yaz-iconv is now installed by default along with the man page
2314 Extend configure check for OpenSSL to use pkg-config where available (such
2317 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2318 server to specify uid/gid/mask for socket using the format
2319 unix:[user=uid,][group=gid,][umask=mask,]file=path
2320 If file= is omitted the existing format is assumed, e.g.
2322 in which case the mask is 0666 (rw for everybody).
2324 Major restructure of YAZ source. All source in libyaz is in src directory.
2325 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2326 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2328 Added man page for utility yaz-marcdump (used to be called marcdump).
2329 yaz-marcdump is installed by 'make install'.
2331 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2332 of incoming package failed.
2334 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2336 Change prototype of odr_perror: add const to message string.
2338 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2340 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2341 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2342 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2343 DNS lookup. There should not be any compatibility problems with this
2344 assuming that blocking=1 or 0 is used.
2346 Fix bad reference in UNIX comstack in function cs_addrstr.
2348 Fix for compilation on AIX.
2350 The generic front-end server (server/seshigh.c) now supports returning
2351 Init diagnostics to the client in User-information-field, in
2352 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2355 --- 2.0.4 2003/09/04
2357 Allow any CQL relation (not just all,any,exact,scr).
2359 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2360 that features the same UI.
2362 Implemented command update0 in YAZ client which is equivalent to
2363 update but uses old of Ext Update ASN.1.
2365 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2366 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2367 Previously no OID was used for this info.
2369 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2370 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2371 returns 'malformed search term' otherwise.
2373 SortResponse member resultCount now set to NULL in sort handler of
2376 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2379 Add three new utility functions for translating OIDs between various
2380 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2381 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2382 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2383 char *oid_to_dotstring(const int *oid, char *oidbuf);
2384 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2386 Reverted modifications for ES Update definition for z_IU0Update
2387 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2388 is back to YAZ 2.0.2.
2390 String value attributes for CCL parser.
2392 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2393 which their FirstSearch server returns in Init responses, sometimes
2394 carrying useful diagnostic information when Init fails. This has the
2395 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2396 "z39.50/oclcui.asn", where its definition is somewhat different from
2397 what OCLC document on their web-site, as required to interoperate with
2400 Support for anonymous authentication in yaz-client. Use the command
2403 * Fix the OID of the Index Data-local "admin" Extended Service from
2404 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2405 the 1000, which indicates a locally-defined OID, was a mistake.
2407 --- 2.0.3 2003/06/20
2409 Fix CCL directive @case handling so that it affects string match for
2410 both CCL keywords and qualifiers.
2412 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2413 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2414 Decoder has been updated with ASN.1 changes as listed in
2415 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2416 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2417 z_IUUpdate, remains unchanged.
2419 ZOOM_record_get may now return a record in a specific character set.
2420 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2421 "from" is the character set of record as returned by target. "to" is
2422 the character set to be returned. If omitted, "to" is UTF-8.
2424 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2426 New ODR utility, odr_getelement, which returns name of element for
2427 which encoding/decoding failed.
2429 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2430 in cases where a required element was omitted.
2432 Bug fix: some MARC8 sequences were not converted.
2434 New ZOOM option "step" which specifies number of records to be
2435 retrieved in one chunk. Used in conjunction with "start" and "count".
2437 SRW support for yaz-client. Use scheme http: to use it, e.g.
2440 yaz-client no longer does (un)intelligent character set conversions
2441 by default. Can be enabled with charset and marc_charset commands.
2443 xmalloc trace fix for 64-bit systems such as DEC alpha.
2445 Solaris 2.6 compile fix.
2447 New function, cql_strerror() translates SRW error codes, as returned
2448 by cql_transform_error(), into human-readable English strings. Used
2449 in yaz-client diagnostics when appropriate.
2451 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2452 converts it into a type-1 query which is sent to the server. This
2453 makes CQL available for use with all Z-servers, as opposed to the tiny
2454 minority that can handle CQL queries themselves.
2456 --- 2.0.2 2003/04/28
2458 New Debian package layout similar to the Redhat Package layout.
2460 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2461 and search result respectively.
2463 --- 2.0.1 2003/04/25
2465 Redhat package is now several packages: libyaz (runtime libraries),
2466 libyaz-devel (development and documentation, and yaz (utility programs).
2467 Package spec file by Morten Bogeskov.
2469 New member 'schema' in struct bend_fetch_rr which the name of requested
2470 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2471 handler MAY set this to reflect the schema of the returned record.
2473 New member 'display_term' in struct scan_entry. GFS now sets member entries
2474 and allocates scan entries to be filled by user scan handler. In previous
2475 version, entries member was allocated by the scan handler. That still works,
2476 but the GFS will ignore member display_term - assuming it was NOT set by
2477 the handler. The fact that the GFS now allocates the entries both allows
2478 for new members and makes a scan handler easier to write.
2480 Fix CQL lex buffer overflow.
2482 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2483 SRU default recordPacking is string.
2485 SRU protocol support for frontend server.
2487 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2489 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2491 Added scan for the ZOOM shell (zoomsh).
2495 * String Identifers for Schemas (Amendment 5).
2496 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2497 Old definition for schema
2498 Odr_oid *schema; /* OPT */
2503 Z_InternationalString *uri;
2504 #define Z_Schema_oid 1
2505 #define Z_Schema_uri 2
2508 * resultCount parameter to Sort Response (Amendment 1).
2509 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2511 Support for SRW 1.0 over HTTP. This is an optional feature and
2512 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2515 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2516 on the same port. SRW SearchRetrieveRequests are mapped
2517 to bend_init,bend_search,bend_fetch,bend_close.
2519 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2521 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2522 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2524 ZOOM connections are SRW based if schem http is used for hostname
2525 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2526 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2528 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2529 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2530 distance=n, order=true/false, relation=le, prox unit=word. If
2531 n is omitted, distance 1 is used.
2533 Fixed problem with C compiler include path in wrong order.
2535 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2536 on Solaris. Patch from Ko van der Sloot.
2538 New MARC decode API. All new functions operate on a yaz_marc_t
2539 handle. The most important new functions are: yaz_marc_create,
2540 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2541 decode and destroy respectively. Decoder can produce formats
2542 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2543 include/yaz/marcdisp.h.
2545 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2546 to UTF-8, UCS-32, wchar_t or Latin-1.
2548 * Prototypes for yaz_iconv_-functions moved to separate header
2549 include/yaz/yaz-iconv.h.
2551 Make a few private functions 'static' in unix.c. This prevents
2552 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2554 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2555 are set when Init Response is received.
2557 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2558 but returns diagnostic set as well.
2560 New function yaz_strerror which is a portable wrapper for
2561 strerror/strerror_r/GetLastMessage.
2563 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2564 is returned for MARC. If type is "oai", then OAI MARC is returned.
2566 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2569 --- 1.9.2 2002/11/26
2571 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2573 Fix bad race conditions on SIGTERM and terminate gracefully in
2576 Move retrieval (data1) module to Zebra since nobody seems to be
2579 Add GRS-1 render for ZOOM using same format as yaz-client.
2581 --- 1.9.1 2002/10/05
2583 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2585 Fix broken ESpec handling in data1 module.
2587 SGML reader parses comments and makes them part of the data1 tree.
2589 Added several type casts so that YAZ compiles as C++ code.
2591 ZOOM didn't handle PDU encoding failures properly.
2593 Added more Bib-1 diagnostics (approved extensions).
2595 GNU configure: better check for iconv.
2597 More portable use of accept, getpeername. Check for socklen_t. Use
2598 int/size_t if socklen_t is not defined.
2602 PQF parser rejects bad queries - including those with extra
2603 characters in them. PQF parser used to silently ignore that.
2604 Cleaner API for PQF added, which allows you to get detailed
2605 error information for bad queries (see yaz/pquery.h).
2607 Fixed bug in ZOOM_record_get for type "database".
2609 Implemented mini iconv library supporting conversions between
2610 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2612 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2614 --- 1.8.9 2002/08/20
2616 Fixed ZOOM C record cache so that preferredRecordSyntax and
2617 elementSetName is used to check for already fetched records.
2619 --- 1.8.8 2002/08/02
2621 Added three members in bend_initrequest structure to facilitate
2622 character set negotiation.
2624 Fixed a bug in frontend server that could cause indefinite
2625 loops under rare conditions.
2627 Revised character set utilities (charneg.h) so that encoding
2628 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2630 For PQF, directive @term <type> sets term type for Scan/Search.
2631 Here <type> is general, string, numeric, null. The term type
2632 is inherited - just like @attr.
2634 New call odr_set_charset that sets character set conversion for
2635 international-strings on a ODR stream. Prototype is:
2636 int odr_set_charset(ODR o, const char *to, const char *from);
2637 The InternationalString is still represented as C string in YAZ
2638 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2639 won't). On the protocol level, you can use any encoding.
2641 Support for UNIX sockets in ZOOM.
2643 Solaris recv sometimes returns errno == ENOENT. It is treated as
2644 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2646 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2647 both client and server. Code by Morten Bogeskov.
2649 --- 1.8.7 2002/05/22
2651 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2652 that they can be used directly from Visual Basic. You must recompile
2653 your windows APP if you're using ZOOM.
2655 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2656 Commands "lang" and "charset" sets language and character set respectively.
2657 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2658 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2660 Attributes from multiple CCL fields may be OR'ed rather than merged
2661 using directive "@field or". Fields are still merged by default -
2662 equivalent to "@field merge".
2664 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2667 Fixed bug in zget for parameter ExtendedServicesResponse.
2671 --- 1.8.6 2002/03/25
2673 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2675 Client displays USR.1:SearchResult-1 (hits per term).
2677 Additional Search Info for search in Generic Frontend Server.
2679 Fixed CCL parsing of "field=s".
2681 WIN32 installer - using the excellent NSIS software from nullsoft.
2683 Fixed CCL parsing of "field = - <number>".
2685 Added function yaz_marc_decode that decodes MARC for line mode
2686 display or XML (similar to that used by JZKit).
2688 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2689 Z39.50. But ISO/ILL was, however.
2691 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2692 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2694 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2695 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2697 --- 1.8.5 2002/02/03
2699 New YAZ client features: Command completion and new commands:
2700 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2701 Code provided by Jacob Poulsen.
2703 New call oid_trav, that visits all registered OIDs via callback.
2705 Function ZOOM_record_get now returns const char pointer rather than
2706 void pointer. It saves a lot of type casts.
2708 For YAZ client, command "auth" now allows you to set authentication
2709 in IdPass style. It is enabled when three tokens are given - order
2710 is user, group and password.
2712 Fix memory leaks in MARC record handling for ZOOM.
2714 New option for YAZ client, -k <kilobytes> that sets
2715 maximum record size. Similar to -k option for generic frontend
2716 server and yaz-ztest.
2718 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2720 Prefix query parser reports "fail" when bad attribute set is given.
2722 Fix in MARC decoder. Proximity logging. Fix for attribute set
2723 in scan handler for server. Patches by Shigeru Ishida.
2725 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2728 Configure option --with-openssl=<dir> now works when a directory is
2729 specified. Patch provided by Morten Bogeskov.
2731 New option for YAZ client, -u <auth>, that sets authentication.
2733 ZOOM fix: error information was sometimes "missing", since error
2734 was cleared/reset too when it shouldn't.
2736 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2738 --- 1.8.4 2002/01/04
2740 Scan for ZOOM API. New object ZOOM_scanset. New functions
2741 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2742 ZOOM_scanset_destroy.
2744 New ZOOM function, ZOOM_connection_last_event, that returns type
2745 of last event (such as "receive data", "send data", "apdu received",
2748 New ZOOM option, schema, that specifies schema for retrieval.
2750 New CCL feature. Qualifiers can be aliases for one or more
2751 other qualifiers (if more than one is given, OR is used).
2753 ZOOM uses named result sets if target supports it.
2755 Two new YAZ client commands: . (dot, which sources a script of YAZ
2756 client commands), and ! (to execute shell command.). Implemented
2759 Working on Debian packages.
2761 --- 1.8.3 2001/11/19
2763 YAZ client enables named result sets only if target supports it.
2765 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2767 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2768 with key="host" to get same result.
2770 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2771 Function Z3950_resultset_record(s) returns references to records
2772 "owned" by resultset. To become owner use Z3950_record_clone.
2774 Function z_ext_record handles Extended Services. Thanks to
2777 --- 1.8.2 2001/11/12
2779 CCL Parser fix: ignore token comma when dealing with and-lists.
2781 Documentation updates for COMSTACK.
2783 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2784 Changed prototype Z3950_records. For some functions, int parameters
2785 were changed to size_t.
2787 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2790 New MARC decode/display function, marc_display_exl, which properly rejects
2791 non-ISO2709 records. YAZ client uses it.
2793 --- 1.8.1 2001/10/29
2795 Fix bug: local attribute set wasn't set correctly in PQF strings.
2799 * Old Z39.50 codecs no longer supported.
2801 Added ZOOM C binding. See http://zoom.z3950.org/
2803 Renamed states for COMSTACKs to avoid confusion with events.
2805 Implemented cs_look and proper cs_rcvconnect.
2807 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2809 Configure detects POSIX threads on OpenBSD.
2811 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2812 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2814 When error is returned from present handler, non-surrogate diagnostic
2815 is returned in present response (and fetch handler is no longer called).
2817 * Minor adjustments to pquery parser (PQF). Token characters may be
2818 escaped by using backslash (C-style).
2820 PQF parser allows string attribute values to be specified. For @attr,
2821 non-numeric characters after the equal-sign are treated as strings
2822 (e.g. @attr 9=title).
2824 CCL trunction character may be defined (@truncation in file)
2826 * function zget_ExtendedServicesRequest sets waitAction to
2827 waitIfPossible (was wait).
2829 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2832 CCL operator names may be set in field definition files (CCL_bibset).
2833 See ccl/bib1 for an example.
2835 Fixes in ASN.1 compiler for C++ compatibility.
2837 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2838 and "op_or" to avoid conflict with C++.
2840 Fixed problem with GNU readline detection on Redhat 7.0.
2842 Added step-size for Scan backend handler.
2844 Fixed bug that made the frontend server crash when no attribute
2845 set was specified for scan.
2847 Front-end server automatically switches to original working directory
2848 when installed as an NT service. Previously -w had to be specified to
2851 Added extended attributes for retrieval module (data1), so that data1
2852 records carry d1_readXML/SGML attributes. d1_read also supports
2853 null-data rules ( <tag/>)
2855 On UNIX when POSIX threads are available, a separate library libyazthread
2856 is created. Programmers should link with that library and the yaz library
2857 when using threads. The reason for the split was that some applications
2858 on Linux, such as Apache, doesn't work well when using shared objects that
2861 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2862 (or any frontend server) in SSL mode by specifying ssl: followed by
2863 address. Only tested on UNIX.
2865 Added feature for CCL module. Virtual structure s=al or s=ol generates
2866 and-list and or-list respectively instead of phrase search.
2870 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2871 log_mask_str. This was done to avoid name conflicts with other libraries
2872 (such as other PHP extensions).
2874 Added raw OID member for preferred record syntax (request_format_raw)
2875 and returned record syntax (output_format_raw) for backend fetch method.
2877 Config file yaz-config now accepts options so that it returns specific
2878 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2880 Shared library support for UNIX using GNU libtool.
2882 * Modified backend interface. Request/Response struct's replaced by
2883 one read/write C struct. For example bend_fetchrequest and
2884 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2885 Every handler - even search has to be registered in bend_init
2886 handler. This means that the YAZ library no longer refers to
2887 external functions and it makes it possible to make the whole
2888 thing a single DLL/SO.
2890 Added Segment handler for backend server.
2892 Added Zmbol/Zebra administrative functions to YAZ client.
2894 Threaded frontend server on UNIX (when POSIX Threads are available).
2895 Starting the server with option -T enables multi-threading.
2899 Added configure option --enable-comp/disable-comp to control use
2900 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2901 located in sub directory asn.
2903 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2904 in ${exec_prefix}/bin along with the other programs yaz-client and
2907 GNU automake used to maintain makefiles.
2909 Added several OID's.
2911 Changed retrieval module so that we can load records with no abstract
2912 syntax defined. Tagpaths in these records are fully composed of string
2915 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2919 On UNIX, the generated makefile now supports a proper 'make install'.
2920 The prefix can be set via GNU configure to set the install location
2921 (default is /usr/local).
2923 * YAZ programs client and ztest were renamed to yaz-client and
2924 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2925 locations, such as /usr/bin,/usr/local/bin,etc.
2927 * YAZ Header files were moved from include to include/yaz. YAZ Header
2928 files are referred to as include <yaz/log.h> rather than <log.h>.
2929 The YAZ include path (-I ..) is therefore the same as before. Programmers
2930 should update their #include statements or use -Ipath/include/yaz
2931 instead. The main motivation for doing this change is that YAZ header files
2932 can be installed in "standard" locations /usr/include,/usr/local/include
2933 without introducing conflicts, since ALL YAZ header files are stored
2934 in subdirectory yaz (under /usr/include for example).
2936 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2937 rather than project/workspace files. We switched because project files
2938 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2941 Changed name of logging function, logf, to yaz_log, to prevent name
2942 clash with some math-log functions. The YAZ header log.h defines logf
2943 to yaz_log (#define) so there should be no incompatibilities by this
2946 Added bend_start/bend_stop handlers for server. These handler are
2947 called on start/stop of server. For windows they are called whenever
2948 a service is started/stopped.
2950 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2951 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2952 in util/yc.tcl. The auto-generated C code structures are, in a few
2953 cases, incompatible with the old decoders. There are differences in the
2954 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2955 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2956 The preprocessor variable ASN_COMPILED is defined when the compiled
2957 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2958 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2959 wish to use the old encoders/decoders you can specify --disable-yc
2962 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2963 version so that it supports both new - and old version of DB Update
2965 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2966 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2967 change. The name parameter can be set to 0 in which no name is specified
2968 for the construction. The macros odr_implicit and odr_explicit sets name
2969 parameter to zero for the construction involved. New macros
2970 odr_implicit_tag and odr_explicit_tag are similar to the others,
2971 except that a name parameter is added. For programmers' that don't use
2972 ODR they probably only need to change the call to z_APDU and z_External.
2974 Added access control facility by interfacing the TCP wrapper library.
2975 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2976 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2977 name of the daemon and enables the access control as specified in
2978 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2980 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2981 den Dool <H.M.vdnDool@kub.nl>.
2983 Added reference ID parameter to most functions in server API - refer
2984 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2986 Changed name of ccl library to libccl.a (was ccl.a).
2988 Fixed bug in decoder for Explain (Category TargetInfo).
2990 Added support for GNU readline in client. Thanks to Jacob Poulsen
2991 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2993 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2994 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2995 IMPLEMENTATION! This change was made to the development version before
2996 the ZIG decided to retract the amendment. If any users MUST be
2997 compatible with the original Update definition, PLEASE CONTACT US, and
2998 we will include a separate definition corresponding to the old Update
2999 ES. Note that because of the change to the ASN.1 of the
3000 TaskPackageRecordStructure we cannot define a single structure that
3001 will support both versions.
3003 * Added const modifier to buffer parameter for some ODR/BER encoding
3004 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3005 completeWAIS, odr_dumpBER.
3007 Fixed bug in client.c which caused a crash when a scanResponse didn't
3008 contain positionOfTerm.
3010 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3011 * will cause an error in a client if a non-YAZ target sends both a
3012 * list of Scan entries and non-surrogate diagnostics.
3014 Retrieval module enhancements. Tag sets may be typed in the reference
3015 to it. From the .abs-file the "tagset" directive takes a third optional
3016 integer type for the tag set referenced. From a .tag-file the "include"
3017 directive takes a third optional type as well. The old "type" directive
3018 in the tag set itself is still recognized but acts as the default type
3021 Backend interface change. Individual Scan terms returned from bend_scan
3022 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3023 in include/backend.h.
3025 Retrieval module enhancements. Multiple tag sets and attribute sets may
3026 be specified in abstract syntax specs. Revised the error/warning for
3027 logging messages reported by the retrieval module when reading the
3030 Object Identifier system (oid_..) changed. The API is backwards
3031 compatible but the oid-routines now allocates new OID's when needed.
3032 Raw OID's may be specified in oid_getvalbyname.
3034 YAZ now uses GNU configure to generate Makefile(s).
3036 * Minor changes in some of the member names of DeleteResultSetRequest and
3037 DeleteResultSetResponse. See include/proto.h.
3039 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3040 and added member 'languages' in TargetInfo (which was missing).
3042 Changed the way attribute sets are handled in the retrieval
3043 module. These are now cached, just like the abstract syntaxes
3046 Changed YAZ so that it links with compiled ASN.1.
3048 Added Explain-schema definitions and mapping routines. The following
3049 Explain categories have been implemented: AttributeDetails,
3050 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3052 Fixed minor bug in Windows version of Server Library.
3054 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3056 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3058 Added EXTERNAL: UNIverse Resource Report (non-standard).
3060 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3061 ENUMERATED and SET OF.
3063 * Added 'const' to some of the char pointer arguments for the
3064 functions, data1_read_node, data1_getelementbytagname,
3065 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3068 Fixed bug in data1_insert_taggeddata - the last_child member of
3069 parent wasn't initialised.
3071 * Changed data1_read_record and data1_read_node so that the supplied
3072 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3073 doesn't refer to any parts of the "SGML"-buffer.
3075 Fixed bug in server library (Windows version of statserv_remove).
3077 * Changed code so that it compiles as C++. The type definition
3078 of Odr_fun which is a member of Odr_arm was changed. The result is,
3079 that an explicit typecast is needed for the fun pointer when
3080 using Odr_arm - as in:
3081 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3083 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3085 Implemented the new structured date and time definition as approved
3086 by the ZIG. Added schemaId element to the specificTag in Espec-1
3087 (also approved at the last ZIG). Thanks to RVDM.
3089 Added some Object identifiers (RVDM).
3091 Changed the Update Extended Service (RVDM).
3093 Added command "refid" to client which specifies referenceId for
3094 the following requests.
3096 Implemented extended service handling for server. See ztest.c
3097 for an example as well as backend.h. New handlers are registerd
3098 in the Init handler.
3100 * Changed interface for sort in server.
3102 Added new members to statserv_options_block. It allows a server
3103 to read options from another source than just the command line. Thanks
3104 to Charles Woodfield.
3106 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3107 renamed to zboolean. Some C++ compilers complained about the name.
3109 Minor changes to gils.abs. Added index 's' (sort) on title
3110 and date/time-last-modified.
3112 --- 1.4pl2 1998/1/30
3114 Fixed bug in server library regarding inetd mode (-i). This bug
3115 was introduced by release 1.4.
3117 --- 1.4pl1 1998/1/29
3119 Added sort facility in client and backend server interface.
3121 Fixed problem with dependencies in Makefile(s).
3123 Fixed bugs for encoders/decoders of extended services and
3126 Implemented sub-tree feature for schemas. Sub-trees are
3127 referenced in *.abs-files. See explain.abs for an example
3128 of the use of this feature.
3130 Modified bib1.att; local attributes for ANY didn't include
3131 ANY itself (only affects use of the retrieval module).
3133 Fixed bug in plain SGML reader in function data1_read_node:
3134 tags with prefix "var" was incorrectly interpreted as variants.
3136 Added feature "sub-schemas" to enable references to - and definitions
3137 of - group of elements.
3139 * Removed member parent from type data1_element (in data1.h).
3141 Implemented function odr_nullval() that returns the value of
3144 * Removed member num_children from data1_node (in data1.h).
3146 Made NT service interface part of the server library. The
3147 function statserv_main uses the NT service when required and
3148 calls the statserv_start / statserv_close routines.
3150 Routine zget_SearchRequest and zget_PresentRequest fills
3151 resultSetName/Id member with "default" instead of "Default".
3153 Fixed memory leak in server. Request queue member wasn't freed.
3155 Fixed nmem_exit so that memory is freed.
3159 Revised the CCL parser utility to be thread safe.
3161 Added function, oid_ent_to_oid, to replace the function
3162 oid_getoidbyent, which is not thread safe.
3164 * Added nmem_init and nmem_exit to initialize and release
3165 NMEM resources. Function nmem_init should be called once in the
3166 initial thread before NMEM/ODR is used. statserv.c and client.c
3167 have been changed accordingly. The change was necessary to make
3168 NMEM thread safe. The NMEM memory pool is shared amongst threads
3169 in a process. Unix-based applications will still work fine without
3172 Added NT Services interface for the the Z39.50 (statserv) Server.
3173 Refer to the ztest.c source on the usage.
3175 Windows 95/NT port using MSVC5.0. Project files are included in the
3178 * Defined new 'global' handle for the retrieval (data1) system. The
3179 new handled, data1_handle, describes the state of the data1 system.
3180 This handle is passed as first argument to virtually all
3181 data1 related routines. The functions data1_create and data1_destroy
3182 creates and destroys a data1 handle respectively.
3184 Added ODR encode stream member to all backend request structures
3185 init, search, scan etc. This stream should be used to allocate all
3186 memory used for the response when thread safe operation is needed.
3188 Changed the comstack utility, cs_addstr, to be thread safe. The
3189 returned hostname string returned by the function is now part the
3192 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3193 function. The cs_straddr takes a COMSTACK handle as argument, so this
3194 function must be used after cs_create and before bind/connect.
3195 This function is thread safe.
3197 Moved test server to 'ztest' directory - generic server code still
3198 in 'server' directory.
3200 Made prefix query (pquery.c) utility thread safe.
3202 Added new function modifier YAZ_EXPORT to 'export' public DLL
3203 functions when using windows (see include/yconfig.h).
3205 Added definitions to the OID database (util/oid.c) (RVDM).
3207 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3209 Added call to ccl_rpn_delete in client program.
3211 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3212 release of RPN structure.
3214 Added support for C++, headers uses extern "C" for public definitions.
3215 With input from RVDM.
3217 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3218 Thanks to Ronald van der Meer (RVDM).
3220 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3222 Added support for private extensions to the OID database
3223 (oid_setprivateoids()). Thanks to RVDM.
3225 Added optional, physical ANY (key replication)
3227 Fixed null-reference problem in GRS-1 output filter.
3229 Proximity operator added to Prefix Query Format (PQF).
3231 In test client command "base" accepts multiple databases.
3233 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3237 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3239 Smallish bug-fixes in the new encoders/decoders (explain).
3241 Bug fixed in DeleteRequest.
3243 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3245 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3247 Added SOIF syntax (using private OID for now) to retrieval module and client.
3249 Added Update extended service.
3251 Added SearchResult-1 additional info structure.
3253 Added optional CCL (ISO8777) interpreter as separate module. Available
3256 --- 1.2 1996/6/10 (1st anniversary release)
3258 Added Summary record syntax. Lightly tested.
3260 Added OPAC record syntax. Untested.
3262 Added ResourceReport service encoders/decoders. Untested.
3264 Fixed bug in z_Unit - wrong tagging on unitSystem.
3266 Fixed bug in the DiagRecs decoder.
3268 Added options for max PDU size and session timeout to frontend-server.
3270 Added documentation of query-language parsers and other supporting utilities.
3272 [frontend-server] Added Attribute set to the bend_scanrequest API.
3274 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3275 surrogate diagnostics were generated.
3277 [retrieval] Allow multiple local values for attribute.
3279 [retrieval] Allow multiple attributes per element in .abs files. index type.
3281 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3283 --- 1.1pl2 1996/4/10
3285 Minor changes, mostly specific to Zebra's requirements (retrieval)
3289 Repaired bug in frontend server when running multiple listening
3290 endpoints in dynamic mode.
3292 z_External() now won't break if a known, ASN.1 value comes encapsulated
3293 in an octet-string. The value will pass through unmodified in an Odr_oct.
3295 Added a bit of code to the demo client to decode & display
3296 ASN.1-structured records represented in the octet-aligned branch of
3297 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3299 Added z_ext_getentbyref() to the ASN module. Doc updated.
3301 * Completed the SCAN definition in the ASN module. This may break SCAN
3302 code based on older YAZ-versions at compile-time. The fix is easy -
3305 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3306 under the SCAN definition. Remember to initialize this, server-people.
3308 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3309 that this does not extend to ODR and ASN.
3311 Comstack allows insertion of established socket (primarily for
3312 inetd-operation of servers). Doc updated.
3314 Front-end server can now start from the inetd in TCP mode. Doc
3317 --- 1.0pl4 1996/1/24
3321 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3322 the rank and record number.
3324 Adjustments to the frontend server.
3326 Fixed diagnostic BER dumper. It ignored the file argument.
3330 Various changes to retrieval module.
3332 Changed the union discriminators of the protocol files from enums to
3333 ints paired with #defines.
3335 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3338 *Changed operator in the RPN structure to 'roperator', again to avoid a
3341 Fixed problems in Explain decoders/encoders.
3343 --- 1.0pl2 1995/12/6
3345 Memory bug in log module fixed.
3347 --- 1.0pl1 1995/12/5
3349 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3351 Bug in Explain DatabaseInfo module fixed.
3353 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3357 The shift to v1.0 signals that we now consider the *core* functionality
3358 of YAZ reasonably stable (the core being more or less equivalent to
3359 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3360 tested (Explain not at all - though that will happen soonish).
3362 Minor changes to code to support Windows port.
3364 Various minor changes after we're getting to use GRS-1 & co. more.
3366 Added Espec-1 format.
3368 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3369 of the protocol and it cannot be selected when encoding (maps into 'string'
3370 when decoding). Needed to talk to some servers.
3372 Demo client can request simple element set names.
3374 Added Diagnostic Format encoders/decoders.
3376 Added simple Close handling to frontend server (no hooks for resource
3377 reporting yet), and demonstration client.
3379 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3381 --- 1.0b3 1995/08/24
3383 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3384 handled incorrectly when records were requested in the searchResponse. This
3385 will only affect you if you use the frontend-server.
3387 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3388 Test-client will ask for and print GRS1. Ztest will return dummy records
3391 Added Explain encoders/decoders to the service-level API. Untested.
3393 Added Extended Services: Item Order encoders and decoders to the Service-
3394 level API. Untested. We could use a recent copy of the pertinent bits
3395 of the ILL protocol to add those bits.
3397 Added diagnostic format 1 encoders/decoders to the service-level API.
3400 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3401 odr_cons.c, which causes a more correct output.
3403 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3404 was always set to 0 when no records were requested in the searchRequest.
3406 * Added better external-handling. This shouldn't harm old code that
3407 *encodes* externals. It can break code that looks for a
3408 'single-ASN1-type' representation, since those types that are known
3409 are now decoded immediately. Look at the SUTRS sample code in
3410 seshigh.c and client.c. Documentation updated.
3412 Handling of structured records in bend_fetchresponse. Length -1 marks
3413 structured record, type is deduced from format field.
3415 --- 1.0b2 1995/06/27
3416 Fairly quick maintenance release to add SUTRS support.
3418 Fixed handling of SUTRS records in the demonstration client.
3420 * Added format field to the bend_fetchrequest and bend_fetchresponce
3421 structures of the backend API (frontend server). When the record is
3422 returned, the value of the format field is mapped to an OID. The
3423 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3424 of the record. The special value VAL_NONE in the bend_request means
3425 that no specific format was requested by the client. Documentation
3426 updated accordingly. Test server (ztest) will return a fixed dummy
3427 SUTRS record if your client requests SUTRS.
3429 Documentation updated accordingly.
3431 You can now set external libraries and RANLIB support in the top-level
3435 First public release.
