1 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
3 OPACXML: sync spelling of availabilityDate in XML to that of Schema
4 opaxxml.xsd. The schema had the correct spelling of this member always.
5 The ASN.1 was mis-spelled and still is (API change) - we are
6 not changing this. However, the OPAC to XML conversion had yet
9 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
12 New function, z_ext_record_oid_nmem, which is similar to
13 z_ext_record_oid but takes NMEM rather than ODR
17 ICU: New conversion element 'join' which joins tokens into one
18 with a custom character given by rule attribute.
22 New GFS search member: present_number. This is a hint to the
23 search handler how many records are going to be fetched immediately
24 following search. There's no guarantee that it's going to be the case,
25 since it depends on hit count (for Z39.50 piggyback) and whether errors
28 Make a few functions static (private). The functions getbyte_stream,
29 ungetbyte_stream and yaz_gets are now private. They were never declared
32 yaz-marcdump: exit(5) for serious decoding errors
34 ISO2709 decoding: be more picky WRT header
36 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
37 was only used as to indicate that next-result-set-position should be
39 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
40 Based on patch from Ashley Sanders.
42 Make some functions static/private in PQF parsing. Those functions were
43 never declared in a public header and so should not be in use by
44 applications based on YAZ.
48 ZOOM: special options to control APDU logging.
49 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
50 logging of APDUs until "saveAPDU" option is set again. If logging is
51 already enabled the effect is that current APDU buffer is cleared.
52 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
53 logging (default behavior on new connection).
54 The APDUs sent/received can be obtained by using
55 Using ZOOM_connection_option_get(c, "APDU") or
56 ZOOM_connection_option_getl(c, "APDU", &l).
58 GFS: relay implementation_version from backend
59 From 3.0.40 and later, implementation_version from backend was
60 not used in init response at all.
64 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
65 mode at all. Probably never did.
67 Make a new version of ztest.pem that, at least, is not expired.
71 Fix description of CCL directive 'case'.
73 More tight checking of form arguments (yaz_uri_to_array). Makes
74 YAZ better at rejecting big and/or bad POSTs.
76 SRU decoding does not report more than up to 10 invalid arguments.
78 rpn2cql: less quotes in generated terms. Semantics unchanged, but
79 it's prettier this way.
83 New utility yaz_decode_init_diag. Defined in proto.h.
85 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
86 given for unix local socket.
87 The COMSTACK string for doing so is:
90 unix:/myfile:tcp:localhost:9999/mybase
91 unix:/myfile:localhost:9999/mybase
92 unix:/myfile:http://fakehost/mybase
94 debian: Use dpkg-buildflags in build process.
98 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
99 global's SRU service uses a recordPosition scheme starting from zero.
100 First record's position should be one
101 according to the standard.
103 --- 4.2.42 2012/10/18
105 Allow more namespaces for SRU. This is to allow, for example, an
106 incorrect namespace returned from server
107 http://services.igi-global.com/sru .
109 Minor fixes for compilation on Windows.
111 --- 4.2.41 2012/10/11
113 daemon: log total number of bad signals from child on stop so that it
114 is more easy to spot problems with child worker processes.
116 retrieval: empty backend name attribute omits element set
117 from being used in retrieval.
119 --- 4.2.40 2012/10/04
121 Implement Solr sort strategy "solr", similar to sru11 sorting.
122 This will implement the correct parameters on Solr requst to do
125 --- 4.2.39 2012/09/28
127 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
130 MARC: Extra/missing indicator handled for MARCXML.
131 The indicator length is given in header and is the same for the
132 whole record. If attributes ind1, ind2 are missing, then content
133 character defaults to blank. Extra indicator attributes (beyond)
134 indicator length are treated as an error.
136 Reformat: delete trailing whitespace
138 --- 4.2.38 2012/09/17
140 MARC: fix non-ASCII characters for leader. This is to ensure we can
141 generate XML in UTF-8.
143 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
144 in one node with structure word.
146 --- 4.2.37 2012/09/04
148 yaz-json-parse: JSON output may be pretty printed by using option
151 Increase default value of max message for Z39.50 Init for GFS, ZOOM
152 and yaz-client. Old value was 1 MB. New value is 64 MB.
154 --- 4.2.36 2012/08/22
156 yaz-client: don't display bogus records from SRU servers. Some SRU servers
157 return more records than given by *maximumRecords*. Skipping those in
160 record_render: simplify buffer return handling and fix at least one bad
161 memory reference, that broke the test_embed_record sometimes.
163 Allow http://user:pass@host notation for yaz_url_exec.
165 zoomsh: allow shell command to be executed. Via the system(3) call.
167 yaz_poll: Allow num_fds == 0
169 yaz-client: fix bad encoding of "itemorder item". The itemorder
170 item <no> - command forgot to use length of encoded Item Request
171 package. Error present since YAZ 3.
173 yaz-ztest: fix bad usage of session handle. Bug was introduced when
174 result sets were saved (271a9c83).
176 SRU recordPacking: guess record packing in response rather than looking
177 at the recordPacking element which, OF COURSE, changed semantics in SRU
180 Decode SRU 2.0 responses. The official namespace for responses, according
181 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
182 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
183 nature.com's server, however, usee namespace
184 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
185 we are now using a glob-expr to match up the namespace. ZOOM C and
186 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
187 I can not find a single real example showing the "real" namespace in
188 the documentation from OASIS. The namespace for requests is different
189 from responses, but this is not added to YAZ yet, when we don't encode
192 --- 4.2.35 2012/06/26
194 zoom/record_render: add support for Base64 decoding fo MARC records
195 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
196 which will decode base64 + ISO2709 marc-8 encoded material from text node
199 --- 4.2.34 2012/06/07
201 Add missing definitions ZOOM_resultset_get_facet_field_by_index
202 and ZOOM_resultset_facets_names.
204 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
207 Change APDU dump printing to avoid long leading blanks. For levels 16
208 or larger the level is shown and the indentation is truncated but
209 recursed with modula 8. This makes it still reasonable easy to read
210 - even for nested BER dumps.
212 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
213 return 0 (incomplete package) in case where the BER package was
214 considered too nested (return value of -2).
216 dumpber: lines of level 15 are not indented further. Two spaces per
217 indentation; indentation 15 or more is indented to a fixed indentation
218 and augmented with a level=<no> indication.
220 zoomsh: increase max size of command+args
222 GFS: No limit in RPN buf size in CQL to RPN conversion.
224 --- 4.2.33 2012/05/09
226 New function for daemon utility, yaz_daemon_stop .
228 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
230 --- 4.2.32 2012/04/25
232 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
233 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
235 --- 4.2.31 2012/04/23
237 YAZ daemon utility relays SIGUSR1 to child process.
239 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
240 would result in en empty database list - which in turn would result in
241 encoding failure for search.
243 Fix reading beyond string in yaz_sort_spec.
245 --- 4.2.30 2012/04/11
247 Add two new SRU diagnostics:
248 236: Access to specified database denied
249 1015: Init/AC: Maximum number of simultaneous sessions for Userid
251 Document the very useful ZOOM-C option "apdulog".
253 CQL to RPN: term may be passed through verbatim. This is enabled with
254 truncation.cql . The assumption being that the term is already CQL.
256 --- 4.2.29 2012/03/20
258 record_conv: leader spec may be given for marc element.
259 The leader spec is given as attribute leaderspec for element marc.
260 For example to convert a MARC21 record from MARC-8 to UTF-8:
261 <marc inputformat="marc" outputformat="marc"
262 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
264 record_conv: allow user-XSLT params. For example:
265 <xslt stylesheet="MARC21slim2DC.xsl">
266 <param name="myparameter" value="myvalue"/>
267 <param name="otherparameter" value="othervalue"/>
270 record_conv: fix error handling for missing marc charsets.
272 CQL: fix extra terms in wrong order.
274 --- 4.2.28 2012/03/06
276 record_conv: modify new API for conversion types. The conversion types
277 may be passed in new functions yaz_record_conv_configure_t and
278 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
280 Avoid mixed statement/variable declare; fixes compilation with Visual
283 --- 4.2.27 2012/02/28
285 Add non-standard SRU diagnostic: 235: "Database does not exist".
286 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
287 Update SRU to Bib-1 diagnostic maps accordingly.
289 CCL: add two new diagnostics for unsupported masking. The new
290 diagnostics are: "Embedded truncation not supported" and
291 "Single charcacter mask not supported".
293 --- 4.2.26 2012/02/23
295 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
297 --- 4.2.25 2012/01/11
299 Build YAZ for Ubuntu Oneiric.
301 CCL: allow parantheses for proximity operands. For example CCL query
302 (a) % (b) is now allowed.
304 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
305 marked dead, rather then being destroyed. If not, the session memory is
306 being free'd before the search/scan handler is finished. Also destroy
307 'request' memory in request_release rather than in various places,
308 which resulted in leaks from time to time.
310 --- 4.2.24 2011/12/21
312 cql_sortby_to_sortkeys: honor sort prefix.
314 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
315 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
316 The rpn2cql family of functions now always returns quoted CQL terms.
318 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
320 --- 4.2.23 2011/12/15
322 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
323 sequence is treated as one. For example, &&a=b&&&c& is identical to
326 --- 4.2.22 2011/12/05
328 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
329 APDUs for a connection to a WRBUF.
331 --- 4.2.21 2011/11/23
333 Fix cql_sortby_to_sortkeys. Completely broken before.
335 Make CCL's @truncation work again.
337 --- 4.2.20 2011/11/09
339 New ZOOM connection setting: tproxy. It's like proxy, but does not
340 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
341 to set resolved address + port for a connection outside ZOOM itself.
343 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
345 --- 4.2.19 2011/11/07
347 Fix uninitialized variable in Solr spell support (could cause SEGV
348 for SRU response decoding).
350 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
351 back-end's addinfo through into the ZOOM response addinfo.
353 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
354 they are separated by a colon and a space rather than simply
357 --- 4.2.18 2011/10/28
359 Add support for Solr spell-checking/suggestions through ZOOM.
360 If a Solr target has been configured correctly for spelling-checking
361 and suggestions, these will now be returned on the ResultSet option
362 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
364 --- 4.2.17 2011/09/28
366 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
367 with a flag whether to substitute escape sequences or not.
369 --- 4.2.16 2011/09/22
371 Fix nmem_strsplit_escape to substitute escape char properly.
373 New option for zoomsh -e , which makes it abort on first error and
374 return process exit code to indicate success/failure.
376 YAZ options utility supports special option -- which makes all it treat
377 all following arguments as non-options.
379 --- 4.2.15 2011/09/16
381 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
382 searched if absolute filename is given.
384 Fix conv_xslt() error-reporting when stylesheet is not found.
385 (The value of fullpath is meaningless in this situation.)
387 --- 4.2.14 2011/09/07
389 Fix problem in CQL sort node creation: un-initialized memory.
391 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
392 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
393 CQL sortby depending on whether Type-1 or CQL is actually sent to the
396 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
397 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
399 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
400 will make it possible to use both single-character mask (#) and wildcard (?)
401 in CCL . Throw diagnostic for left truncation because that is not supported
404 --- 4.2.13 2011/09/01
406 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
407 cases using escapes (\-sequences) and masking.
409 PQF parse fix: A trailing backslash followed by end-of-string (\0)
410 would result in a read one byte beyond string.
412 rpn2ccl may use Z39.50 masking for terms (t=z).
414 ICU check fix. Don't include library -lCrun on Solaris, unless present.
416 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
417 not --cppflags (which seeems like an error in icu-config).
419 --- 4.2.12 2011/08/27 RPM package only
421 cql2ccl: fix conversion of terms: operator characters were not
424 --- 4.2.11 2011/08/25 RPM package only
426 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
427 CCL parser will map both # and ? to their regular expression
428 quivalents (. and .*).
430 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
431 of reserved CQL characters.
433 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
434 is, so that they are passed through.
436 --- 4.2.10 2011/08/24
438 ZOOM SRU mode: more aggressive re-connect.
440 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
441 made available as a utility function, declared in <yaz/logrpn.h>
443 rpn2cql_structure() supports proximity nodes (except that the Type-1
444 proximity node's "exclusion" binary is ignored, as there is no way to
445 express that in CQL). Fixes bug #4564.
449 Fix SEGV that could occur if set command of zoomsh was given without
450 value (2nd argument).
452 Fix SEGV that could occur if unsupported transport was given for
453 COMSTACK - say https (when SSL was unavailable).
455 Build yaz-url on Windows too.
459 New utility to get web content. Header is url.h. A command line tool
460 yaz-url is part of the distribution and packages.
462 Fixes for SSL COMSTACK (when gnutls is in use).
464 New functions yaz_base64{encode,decode}. Header is base64.h.
468 ZOOM C includes HTTP response buffer as additional info if it fails
469 to decode the SRU response.
471 Make wrbuf_json_puts available.
475 zoom: throw diagnostic for invalid value for option "sru". Before a
476 bad SRU request was sent.
478 Adding new utility wrbuf_vp_puts.
480 Add cclxmlconfig.obj to win/makefile. It was missing completely.
484 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
485 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
486 redirect was used at the same time.
488 MARC line mode decoding: be less picky about length given - first
489 5 digits of header that is.
491 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
493 Changes to decoding of SRU records: a record with recordPacking=xml is
494 modified with a new root element <yaz_record> if the recordData contains
495 multiple children elements. This is to make the record XML parseable
498 RPN to SOLR conversion: encode special characters.
500 Generic Frontend Server: fix uinitialized member, stepSize.
504 Fix a bug in SRU decoding of records.. The database records stored
505 had un-initialized memory, but it would only be seen with yaz_record_render
506 and type_spec="ext" .
508 Fix a bug in ccl_qual_dup introduced in 4.2.3.
512 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
516 Add new utilities to convert from CQL to CCL . These utilities have
517 prefix cql_to_ccl defined in cql.h.
519 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
520 lead to memory heap corruptions when ICU utilities were in use.
524 Make compilation work without Libxml2.
526 yaz-client: remove redundant blanks in display of searchResult-1 term
531 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
532 resulting CQL node (tree) in a new node CQL_NODE_SORT.
534 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
535 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
536 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
537 Note that the CQL sortby spec is only converted when the GFS is already
538 converting from CQL to RPN (cql2rpn element).
540 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
541 specify whether to collapse delimitors or not. The existing nmem_strsplit
542 do collapse (collapse parameter = 1).
544 Windows installer: For NSIS, set InstallDir depending on x86/x64.
546 Rename internal func yaz_use_attribute_create. While non-static, this
547 function is not declared in a public header.
551 Add -lCrun when linking with ICU on Solaris.
553 More quicks character set conversions for OPAC records.
557 fix problem with record_render: records were converted (character set
558 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
562 SRU: add methods for handling DADS SRU-proxy facets.
564 Separate OPAC record character set for ZOOM_record. yaz_record_render
565 allows a character set given as charset=from/opacfrom,to where 'from' is
566 the character set of a bibliographic record, 'opacfrom' is character set
567 of OPAC record and 'to' is the target character set.
571 yaz-client: show may XML format records. Command show followed by 'format'
572 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
575 src/stemmer.c: Avoid using unnamed union. It is not supported by some
578 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
581 Update yaz.spec to operate on both SLES11 / Centos 5.5.
583 RPM: Release includes 'indexdata' name. Use indexdata in release name so
584 this package can be distinguished from other vendors.
586 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
587 as determined by configure
589 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
591 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
592 returns no error and no record, the present request is considered
593 partial (only a subset of the records could be returned by backend), and
594 so it is appropriate to set Present Status to partial-4.
598 Move yaz-config man pages to section 1.
600 More documentation about SOLR.
602 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
603 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
604 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
605 peers on some Linux systems. However, in general that does not work
606 so YAZ can not rely on that to work. Debian changed behavior in this
607 respect from Debian lenny to Debian squeeze (still testing as of Oct
609 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
611 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
615 Fix yaz-config output: echo_source not set correctly by configure.
619 SOLR WebService support for yaz-client and ZOOM.
621 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
623 --- 4.0.12 2010/08/17
625 Z39.50 facet support. Facet specifications are passed for search in
626 other-information with ASN.1 as defined in facet.asn and OID
627 .10.1000.81.5 . Facets are expressed as an Attribute list as known
628 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
629 3 is limit (number of entries to get in response). yaz-ztest returns
630 dummy facets if a client asks for them.
632 --- 4.0.11 2010/07/09
634 CCL fixes: bug 2895 and bug 3539.
636 GR1-display: add comma in display - was removed by mistake in
639 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
641 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
643 --- 4.0.10 2010/06/18
645 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
646 result set from a connection. The result set will be on its own
647 thereafter; no operations on it will perform retrievals from a target.
648 Only cached copies are returned.
650 ZOOM C:fix case for HTTP servers responding with Connection:close.
651 Ensure that if there is a current task it is resumed (like fetching
652 more records in a result set) . Bug #3484.
654 PQF parser: use odr_atoi for Odr_int (not atoi)
656 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
657 values that contain any non-digits are treated as string attributes
658 (previously decoding only checked for leading character ([0-9]). PQF
659 encoding: attribute string values are not surrounded by double-quotes.
663 New utility for managing threads - thread_create.h.
665 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
666 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
667 but YAZ' implementation do.
669 Fixes for yaz_cond-functions on Windows 7.
671 DLL export more symbols.
673 zoomsh: show record do NOT render opac.
675 Remove *.la files from Debian and RPM packages.
679 Debian package libyaz-dev depends on libgnutls-dev again (was
680 removed in YAZ 4.0.6, but due to Libtool it is still needed
681 even though yaz-config do not list libgnutls libs).
683 ZOOM: Use only one WRBUF for returning string results for
684 ZOOM_resultset. Reduces memory usage for ZOOM in general.
686 ZOOM: ZOOM_connection do not use a shared pointer to
687 ZOOM_resultset after ZOOM_resultset is destructed by
688 user. Reverts to YAZ 4.0.4 behavior.
692 record-conv: fix problem with at least one XSL conversion -
693 due to probably incorrect usage of XML XSL documents.
697 Fix yaz-config for static mode and the use of SSL (gnutls).
701 Forward decl timeval struct in mutex.h and gettimeofday.h.
703 yaz-config: fix 'static' mode linking.
707 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
708 are wrappers for pthreads or Windows. For Windows these are put in
709 a separate DLL: yaz_cond4.
711 libyaz.la (whole source) is compiled with thread. If thread support
712 is enabled enabled, all source of YAZ is compiled with treading support.
713 This allows core utilities such as yaz_log to use thread facilities.
714 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
715 thread utilities. This commit moves mutex utilities (mutex.c) from
716 libyaz_server.la to libyaz.la.
718 yaz-json-parse displays leading text until error.
722 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
723 patch from Giannis Kosmas.
725 SRU: no longer URL encode SRU database. The URL for an SRU server is
726 a URL and such is alreeady encoded - at least when given with leading
727 http:// or https://. This reverts behavior to YAZ 3.0.50.
729 Support for new MARC XML notation TurboMARC which like MARCXML is a
730 complete representation of MARC/ISO2709.. This one, however, is more
731 compact and allows for faster processing with XSLT. TurboMARC can be
732 used in the marcdisp.h API, from the yaz-marcdump utility and from
735 yaz-ztest can be configured - via the database - to perform certain
736 delays when it performs operations search, present and single record
737 fetch. This allows testers to make yaz-ztest act as a real or even slow
738 Z39.50 server. Refer to the yaz-ztest man pages for details.
742 wrbuf_destroy allows NULL WRBUF passed to it.
744 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
746 Add ZOOM_connection_close.
748 No fixed size buffers for ZOOM shell - bug #3257.
750 tstodr: make it work on s390 platform.
752 New icu iterator-functions. The new icu_iter-functions makes it possible
753 to use ICU chains from many threads.
755 yaz-client: better syntax check for show command.
759 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
762 New simple local-file XML include facility which allows file glob-patterns.
763 Refer to yaz/xml_include.h.
765 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
768 ZOOM_record_get supports new parameter "format" which makes it format XML
771 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
772 JSONText in ECMA-262) is JSONValue, not JSONObject.
776 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
777 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
779 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
780 POSIX/Unix builds .so with major version 4.
782 Remove old LOG_-defines from log.h. They have been obsolete and
783 undefined by default for the last 5 years.
785 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
787 GFS: Remove socket (int *fd) from search_rr handler. The socket
788 descriptor ptr is a facility that allowed a search handler to supply
789 a socket which would serve as a callback - when search was complete.
790 This facility has now been in use for years.
792 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
793 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
794 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
795 returns 'const char *' rather than 'char *. The returned string is
796 read-only and should not be modified by applications. COMSTACK cs_close is
797 now a void function - it no longer returns int. No applications check for
798 the value and the implementations has always returned 0.
800 ZOOM: use size_t for scan hit counts and str size. Functions
801 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
802 occ (hit count) and len (string length) are now of type size_t pointer
803 rather than int pointer. This is to be able to represent large hit counts
804 and to also just to use the proper type for string length (strlen result).
806 New JSON parser. Refer to include/yaz/json.h .
808 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
809 Used to be int in some cases. Many wrbuf_-functions used to return an int
810 indicating some length.. These return values were never used. And so they
813 ODR: odr_malloc, odr_total now takes size_t for size.
815 clone_z_type: fix leak; occurred for encoding failures.
817 --- 3.0.52 2009/12/03
819 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
820 bug was introduced in 3.0.51.
822 --- 3.0.51 2009/12/02
824 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
826 tcpip comstack: fix leak for getaddrinfo.
828 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
829 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
830 Decoding of SRU "path" database is performed by private function
831 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
832 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
834 yaz-client: honor base command for SRU. Change when database setting
835 is applied for SRU and ensure it is kept when a connection is reset.
836 Change also the way errors are displayed or SRU (decoding of packages).
838 --- 3.0.50 2009/11/02
840 Add support for extra request / response data for SRU codecs and GFS.
841 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
842 for extra data response buffer and length. For the GFS, both request
843 and response data (XML) is carried in extra_args and extra_response_data
844 for the search handler. Patch by Ko van der Sloot.
846 ZOOM: For queries that cannot be converted to the specified rpnCharset,
847 ZOOM now returns a diagnostic on the client-side ('invalid query' /
848 10010). This fixes bug #2113.
850 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
851 cmdfile included a 'quit' command that would result in a memory violation.
853 --- 3.0.49 2009/10/01
855 Make a number of functions defined in xmlquery.c static. These have
856 never been declared in a public header file (yaz/xmlquery.h) and was
857 made public by mistake.
859 Improve speed of character conversions (iconv utilities). This makes
860 conversions from MARC-8 faster.
862 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
863 unless type desired is "raw". This will prevent type "xml" from
864 returning ISO2709 .. Which obviously can not be XML parsed.
866 Fix memory leak in ZOOM that would occur if option apdulog was used
867 on a re-used connection.
869 Frontend server logs HTTP requests.
871 Frontend server now sends Z39.50 close when it times out (sesssion has
872 been idle for too long). Versions 2.0.30 and earlier also sent close.
873 But due to a mistake this was disabled in all versions after that, i.e.
874 the server would just close the socket immediately.
876 yaz-client emits a better message when receiving an unrecognised
877 userInformationField.
879 Skip zero-length subfields when decoding ISO2709. This rare case happens
880 if a record has two FS characters in a sequence. Without this patch
881 there would be a reference beyond char array in using_code_len fragments
884 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
886 --- 3.0.48 2009/08/28
888 The show command offered by the zoomsh command now takes a 3d optional
889 parameter type which is what is passed to ZOOM_record. If the type
890 argument is omitted, "render" is used.
892 RPN to CQL conv may use USE string attributes (bug #2978).
894 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
896 --- 3.0.47 2009/07/08
898 Function yaz_xml2query allows a diagnostic element in the PQF XML
899 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
900 code and additional info respectively.
902 The BER BOOLEAN is now the integral type Odr_bool which still happens
903 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
904 typedef'd to Odr_int. This is still an integral 'int', but it may be
905 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
906 ASN-1 compiler as well as programs has been updated to use the new types.
908 --- 3.0.46 2009/06/08
910 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
911 only the bibliographic record was rendered. For type=opac, an OPAC
912 record is only returned if it is present.
914 iconv: small fix for encoding of advancegreek.
916 yaz-client: avoid double display of SRU/SRW records (bug #2798).
918 yaz-client: option auto_reconnect=on really reconnects.
920 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
922 server: avoid null ptr ref for for yaz_poll errors.
924 build: fix RPM build for RHEL 5.3.
926 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
928 --- 3.0.45 2009/03/31
930 Fixed bug #2709: TCP connect returns Invalid argument.
932 Fixed compilation for mingw.
934 Honor charset for raw records (ZOOM_record_get).
936 Fixed use of errno for threaded mode that was seen on Solaris 10.
938 Fixed argument passing with blanks in value for Windows Service.
940 Disable YAZ' own log rotate by default (no 1 GB limit).
941 The variable l_max_size which specifies the log file limit is set to 0
942 (DISABLED): This is due to the fact that YAZ is most often deployed using
943 logrotate. Also YAZ can not perform log rotate because of unsufficient
944 permissions (setuid).
946 --- 3.0.44 2009/02/17
948 List supported encodings in man page for yaz-iconv.
950 Fixed missing SSL libs for --libs output
952 Re-established OID record syntax application-xml. Nobody should use it
953 but we don't want to change soname because of this symbol being absent.
955 --- 3.0.42 2009/02/02
957 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
959 Added member named_result_sets for init handler struct for the GFS. This
960 allows a server to disable named result sets.
962 Removed OID record syntax application-xml.
964 Added support for rule-based transliterator for ICU wrapper of YAZ.
966 Fixed bug #1902: yaz-icu XML output.
968 Make YAZ checks Emacs friendly.
970 BITSTRING value shows value. Bug #2346.
972 ISO2709 decoding: skip control characters from indicator data.
974 Omit sort key by default in yaz-icu's output.
976 Allow combined single char options (again) for YAZ' options function.
978 Utility yaz-marcdump got option to display YAZ version (-V).
980 Allow YAZ to use ICU 3.4.
982 Added new ICU test case which illustrates removal of diacritics.
984 --- 3.0.41 2008/12/29
986 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
988 --- 3.0.40 2008/12/29
990 For configure, using option --without-xml2 also disables Libxslt/Libexslt
993 Fixed bug #2352: yaz-marcdump crashes for certain record.
995 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
997 Added support for Danmarc2 to UTF-8 conversion.
999 Added support for ISO5426 to UTF-8 conversion.
1001 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1002 implementation version.
1004 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1006 --- 3.0.38 2008/11/10
1008 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1009 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1011 ZOOM C now interprets databaseName option for ZOOM connection as path
1014 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1016 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1018 Dummy Libxml2 types no longer defined in headers of YAZ'.
1020 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1023 --- 3.0.36 2008/09/26
1025 Various ODR chapter fixes.
1027 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1029 Added missing source for Windows compilation, mutex.c.
1031 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1033 For SRU connections in ZOOM all records up to "count" are now fetched.
1035 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1036 in Windows due to bad error handling for Libxml2.
1038 Added facility for sending arbitrary records (ASN.1 any) using
1039 ZOOM C's Extended service update. Patch by Sam Reynolds.
1041 New options for ZOOM C's connection, logapdu which makes ZOOM log
1044 --- 3.0.34 2008/06/18
1046 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1048 --- 3.0.32 2008/06/12
1050 Fixed memory violation that could occur when decoding UTF-8. This bug
1051 was only present in 3.0.30 of YAZ.
1053 --- 3.0.30 2008/06/06
1055 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1056 GNU TLS is used by default (if found).
1058 yaz-ztest returns OPAC records if a client asks for OPAC.
1060 Improved speed of MARC-8 encoding.
1062 Added support for lossy and loss-less MARC-8 encoding.
1064 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1066 Added new Windows Service wrapper (sc).
1068 yaz-client's itemorder command may now send a file.
1070 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1072 Added new function yaz_log_xml_errors.
1074 Allow (but warn) unknown XML attributes in MARCXML parsing.
1076 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1078 The UTF-8 to MARC-8 conversion now uses a different set of characters
1079 for Greek symbols. Bug #2120.
1081 --- 3.0.26 2008/02/21
1083 Added yaz_daemon (daemon.h).
1085 Fixed bug #2068: pkg-config trouble
1087 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1089 --- 3.0.24 2008/01/28
1091 Document --with-xml2 option.
1093 Added OPAC XML XSD (etc/opacxml.xsd).
1095 Allow glob mask for name attribute in retrieval element for the
1096 generic frontend server's retrieval facility.
1098 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1099 except POLLIN/POLLOUT.
1101 Fixed error handling in cs_listen. Bug #2037.
1103 --- 3.0.22 2008/01/20
1105 Fixed version in yaz/yaz-version.h.
1107 Fixed bug #2027: Crash when closing connection.
1109 Changed configure so that ICU support is only enabled if only ICU
1110 and Libxml2 is available (because the ICU chain is XML based).
1112 --- 3.0.20 2008/01/15
1114 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1115 is built. Only this DLL depends on the ICU runtime.
1117 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1118 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1120 Changed license of CCL module to 'Revised BSD'. After consultation with
1121 remaining members of the original EUROPAGATE consortium, we are re-issuing
1122 the CCL module without a separate license. The software was developed by
1123 Index Data as part of a research project. The special license was included
1124 to help feed usage information back to the project consortium to support
1125 project evaluation. At this time, the project consortium has long-since
1126 disbanded, and the majority of the original principals have retired. At the
1127 same time, we have significantly modified the software during the following
1128 years, to the point where very practically no original code remains. To
1129 simplify re-use of the software, we have contacted those members of the
1130 consortium who could be reached, and agreed to re-issue the module as a
1131 proper part of the YAZ package.
1133 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1135 CQL closer to being version 1.2 compliant. CQL also allows free-form
1136 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1139 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1140 bug could make Extended services handling crash in the ZOOM layer. This
1141 bug was only present in YAZ 3.0.18.
1143 --- 3.0.18 2007/12/19
1145 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1148 yaz-marcdump reads and writes collection wrapped records.
1150 Handle OPAC for record conversion module.
1152 Fixes for ICU wrapper.
1154 Allow ICU libs to be controlled with --with-icu .
1156 --- 3.0.16 2007/11/12
1158 Added yaz_poll which is a wrapper for select/poll. When poll is available
1159 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1160 sockets to be in use.
1162 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1163 functionality through an XML based configuration (ICU chain). This system
1164 is useful for search facilities such as Pazpar2 and Zebra that needs to
1165 perform tokenization of indexed material. The ICU code in a separate
1166 library libyaz3_icu.a.
1168 Added HTTP tunnel facility for COMSTACK, bug #1752.
1169 This is a facility that allows a Web proxy, such as squid, to tunnel
1170 Z39.50 traffic. This facility is "transparent" to must applications
1171 using YAZ. It's enabled by using pseudo transport connect: followed by
1172 the proxy address, followed by command, then follwed by he regular
1173 "virtual" addresss. For example,
1174 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1176 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1178 --- 3.0.14 2007/09/21
1180 Fixed bad memory reference in ZOOM_record - cuased by member not being
1181 initialized. This was a problem only in YAZ 3.0.12.
1183 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1184 fields were not removed.
1186 Changed the way C code is generated from codetables.xml. Made a MARC-8
1187 conversion trie for each characterSet section rather than codeTable.
1188 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1189 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1191 --- 3.0.12 2007/09/12
1193 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1194 from ZOOM_record_error).
1196 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1198 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1200 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1202 Better SRW-to-Bib-1 diagnostic mapping.
1204 ZOOM C and yaz-client announces SRU version 1.2 by default.
1206 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1209 Fixed in yaz_sru_decode to allow other version than 1.1.
1211 --- 3.0.10 2007/08/22
1213 Added support for SRU scan for ZOOM.
1215 Added support for the use of the older versions or Extended Service
1216 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1217 set to the version , 1=first, 2=second, 3=third. The third version is
1218 what ZOOM C has used so far. And that, obviously, is the default.
1220 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1221 therefore in Zebra and in SimpleServer-based applications). The new
1222 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1223 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1224 which is passed into the back-end search callback function.
1226 Added support for HTTP Basic authentication in clients: the SRU/W
1227 codec encodes the username/password elements of the PDU structure
1228 appropriately, and these may be set using the "user" and "password"
1229 options in ZOOM-C applications (the same options that are used for
1230 Z39.50 authentication).
1232 --- 3.0.8 2007/06/25
1234 Fixed bug #1208: SSL appears to be broken in ZOOM.
1236 Fixed bug #1206: Libxml2 include path weirdness.
1238 Added oid_name_to_dotstring.
1240 Allow elementSetName to be specified for ZOOM C record update.
1242 Allow waitAction to be specified for ZOOM C based for Extended Services.
1244 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1245 syntax OID. Bug introduced in YAZ 3 series.
1247 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1249 --- 3.0.6 2007/06/06
1251 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1252 directory. yaz-client now reads commands from file given by option -f
1253 if specified; then tries to read .yazclientrc in current directory.
1254 Failing that, it reads .yazclientrc from user's home directory.
1256 Added support for correlationInfo Note and ID for Record Update via
1259 Added yaz-client command querycharset which specifies character set for
1260 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1261 (termListAndStartPoint).
1263 Charset ISO5428:1984 is an alias for ISO5428-1984.
1265 Implemented a way to perform scan in a result set using Z39.50. This
1266 is achieved by attaching the result set name in the characterInfo
1267 (type InternationalString) of OtherInformation in the Scan Request PDU.
1268 The result set is identified in the otherinformation by the new OID:
1269 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1270 This allows for scan in result set and faceted search . Zebra did some
1271 of this in the APT term using attribute type 8 and value being result
1272 set. Using the OtherInformation approach for this is cleaner and easier
1273 to work with in proxies and the like. This facility can be used in
1274 yaz-client using new command setscan which takes a result set as first
1275 argument, start position (APT) as second.
1277 Changed decoding of SRU XML packed records to deal with servers that
1278 have recordData with XML data with multiple root nodes. Also make
1279 comparison for recordPacking case insensitive. Again, one server
1280 returns "XML" where others return "xml".
1282 For SRU responses allow Content-Type application/xml as well as text/xml.
1284 --- 3.0.4 2007/05/21
1286 Fixed bug in character set conversion of BER strings. Bug introduced
1289 --- 3.0.2 2007/05/08
1291 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1293 For OID class, use oid_class consistently.
1295 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1298 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1299 character set for bibliographic information interchange". By Giannis Kosmas.
1301 Added documentation on new OID API.
1303 --- 3.0.0 2007/05/02
1305 Changes to generic frontend server interface: added new member
1306 'query_charset' for bend_initrequest structure. A backend init handler
1307 should set this member to its native character set for query terms.
1308 When defined, the frontend server logic will announce this character set
1309 to a client if the negotiationModel bit is set by the client. All server
1310 implementors are encouraged to specify this. If a backend server does not
1311 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1313 Added CCL utility to remove terms (stop words) from resulting RPN
1314 tree. This is handled by functions with prefix ccl_stop_words_ .
1316 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1317 terms in RPN queries.
1319 Clean-up the CCL API. Moved some internal structures from ccl.h to
1320 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1321 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1322 This is replaced by ccl_parser_find_str which takes a string instead.
1324 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1325 libyaz.la is the core of YAZ except the generic frontend server and
1326 does not depend on POSIX threads anymore. libyaz_server.la is the
1327 generic frontend server facilities and uses POSIX thread functionality
1328 if available. The libyaz.la no longer depends on POSIX threads because
1329 the number of global structures is limited. NMEM no longer re-uses blocks
1330 between threads ; it simply free's memory immediately but allocates in
1331 "large" chunks as usual. We don't expect any performance penalties
1332 because of this. The yaz_log system is still using a global log_level so
1333 caution must be taken when modifying it with yaz_log_init_.. +
1334 yaz_log_mask_str. This, however, should not cause any trouble because
1335 these functions are called during initialization of application code
1336 anyway. `yaz-config --libs server` returns libs for server applications;
1337 `yaz-config --libs` returns libs for non-server applications.
1339 New OID database - with public definitions in oid_db.h. Removed old OID
1340 database including the head oid.h and definitions such as enum oid_value
1341 and struct oident. The new OID database uses the same string names as
1342 before but the 'protocol' is gone. There are now only two representations
1343 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1344 converts from string to OID; functions with prefix yaz_oid_to_string
1345 converts the other way.
1347 Change to emit_term() in CQL-to-PQF query translation: when a term has
1348 the /regexp relation modifier, do not process it for leading and
1349 trailing "^" and "*", which have quite different meanings in regular
1352 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1353 write handlers no longer carries a 'last' parameter. This will make
1354 yaz_iconv flush "less" characters. A flush is performed by call to
1355 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1357 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1358 removed, because function yaz_query_to_wrbuf does the same.
1360 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1361 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1363 Deprecated MARC utility functions removed.
1365 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1368 Branch split: YAZ_2_1_55_branch
1370 --- 2.1.54 2007/03/16
1372 Fix to ZOOM-C so that transparent reconnection is properly handled on
1373 connections that are in asynchronous mode.
1375 Fixed compilation on OpenBSD 4.0.
1377 Large strings in GRS-1 records are now properly displayed in yaz-client.
1379 Added character conversion support for "advancegreek"; based on patch from
1382 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1383 sequence is met. Before the error was not set so it would be unknown.
1385 Adjust yaz-marcdump MARC reader so that it skips until record separator
1388 --- 2.1.52 2007/03/07
1390 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1391 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1392 fd_set structure used as a bitmask for the FDs to be selected on.
1394 Using ACX_PTHREAD macro to check for POSIX threads.
1396 Fixed have-vsnprintf check.
1398 --- 2.1.50 2007/02/23
1400 Fixes for configure on BSD. Bug #900.
1402 Added snprintf/vsnprintf wrappers for systems that don't have
1403 limits (heavens forbid).
1405 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1406 created before all previous tasks were completed and removed from the
1407 task queue, the new task could be removed by a mistake.
1409 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1411 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1413 Fixed bug #832: Problem with MARC/charset in yaz-client.
1415 Fixed bug #668: save command line history for yaz-client.
1417 Fixed bug #830: pkg-config support.
1419 --- 2.1.48 2007/01/23
1421 Extended ZOOM result set options with two options that may be read by
1422 a client: resultSetStatus and presentStatus with values as specified for
1424 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1426 Fixed bug #827: Using SSL fails on Debian etch.
1428 Fixed bug #826: Weird looking chars for set of MARC records.
1430 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1431 that is treated as an ItemOrder with itemRequest being an XML document
1432 external. The value of "doc" is the content.
1434 Extended the GFS search facility. New member of bend_search_rr
1435 'estimated_hit_count' signals that hits is known to be an estmate
1436 (higher or lower than real hit count). New member 'partial_resultset'
1437 signals that the search was partial (hit count is lower or equal than
1438 real hit count). For Z39.50, the information is stored in resultSetStatus
1439 member of SearchResponse APDU. For SRU, the information is signalled
1440 via SRU diagnostic 59: "Result set created with valid partial results
1443 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1445 --- 2.1.46 2007/01/13
1447 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1449 Added ZOOM_connection_peek_event.
1451 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1452 the following new functions:
1453 ZOOM_event_nonblock, ZOOM_connection_process,
1454 ZOOM_connection_get_{socket,mask,timeout},
1455 ZOOM_connection_fire_event_{timeout,socket}.
1456 The existing blocking event handler, ZOOM_event, is a wrapper for the
1457 + blocking ZOOM_event_sys_{poll,select}.
1459 Implemented function ccl_xml_config which parses XML version of CCL
1460 configuration (bug #798).
1462 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1464 Added timings utility (yaz/timing.h)
1466 --- 2.1.44 2007/01/03
1468 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1471 Fixed bug #779: Rotation of apdu.log fails.
1473 Fixed for character set conversions:
1474 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1475 Honor G1 set in MARC-8 decoding.
1477 --- 2.1.42 2006/12/17
1479 Fixed bug #775: char conversion does not handle Alternative UTF-8
1482 Implemented function yaz_marc_read_line which parses MARC line format
1483 records. There is a wealth of formats out there. So far, this function
1484 reads line records produced by yaz_marc_write_line.
1486 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1487 more generic and easier to remember(!) options: -i format and -o format
1488 which specifies input format and output format respectively - where
1489 format is one of "marc", "marcxml", "line", "marcxchange".
1491 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1492 does not print anything except warnings for records.
1494 For yaz-marcdump, added support for MARC split into files (-s) with a given
1497 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1498 spec, at http://www.loc.gov/standards/sru/record-update/
1499 This has changed the binary layout of the following structs:
1500 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1501 bend_update_rr . Patch by Ko van der Sloot.
1503 Added GFS utility function bend_assoc_is_alive which returns 1 if
1504 association is still alive (client is connected); 0 otherwise (client
1505 closed connection). This allows busy servers to stop working for
1508 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1509 been a separate piece of software. This version of ziffy has been modified
1510 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1512 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1514 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1515 Client code may now interrogate options such as "init_opt_sort" to
1516 find out whether the server claims to support various options.
1518 --- 2.1.40 2006/11/27
1520 Added utilities yaz_{set,get}_esn to set/get element set name from
1523 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1524 of YAZ and has been so since YAZ 2.1.10.
1526 Implemented ZOOM_record_error which returns error information for
1527 record (surrogate diagnostic).
1529 --- 2.1.38 2006/10/31
1531 Updates for SRU Update by Ko van der Sloot:
1532 1. Changed name from "operation" to "action"
1533 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1534 versions in the code, marked as 'backward compatible'.
1535 3. Added diagnostics for SRU Update.
1537 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1539 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1541 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1543 For GFS, fixed problem with SRU diagnostic 'First record position out of
1544 range' being issued for 0 hits.
1546 zoomtst10 part of Windows Build.
1548 --- 2.1.36 2006/10/13
1550 Implemented yaz_filepath_comp which splits a path into file path
1551 components (required by Zebra 2.0.3+).
1553 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1554 BSD inspired license until now so this should not have any real impact on
1555 anybody. See http://www.opensource.org/licenses/bsd-license.php
1557 Fixed bug #687: Missing log lines.
1559 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1562 Fixed bug #689: SRU diagnostics to be added.
1564 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1565 whether a connection is idle (no more work do do).
1567 --- 2.1.34 2006/10/04
1569 Change type of optval from long to int for invocation of setsockopt with
1570 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1572 Added support for specifying the max log file size for the Generic
1573 Frontend Server. The size is given with option -r.
1575 --- 2.1.32 2006/09/21
1577 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1579 --- 2.1.30 2006/09/17
1581 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1584 Fixed bug in Generic Frontend Server that could cause a server to stop
1585 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1587 For the generic frontend server, the maximum record size is used as maximum
1588 size of incoming packages (SRU + Z39.50). The value until was previously
1589 only used in Z39.50 Init negotiation and, later, in a session controlled
1590 sizes of records returned. This is controlled using -k option. It can be
1591 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1593 --- 2.1.28 2006/09/04
1595 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1598 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1600 New option for yaz-marcdump -lpos=value which allows setting a portion
1601 of MARC header to a certain value.
1603 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1605 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1606 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1608 --- 2.1.26 2006/08/15
1610 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1613 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1615 --- 2.1.24 2006/08/08
1617 Fixed MARC ISO2709 encoding routines to deal with character set
1620 Minor changes to GFS logging. Database included in search request log
1623 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1624 cached/multiple records.
1626 Shared libraries are built by default on Unix+configure.
1628 Changed cql2pqf transformation to use a different evaluation order. The
1629 new order is: always, relation, structure, position, truncation, index
1630 and relationModifier. Old order was: always, relation, relationModifier,
1631 structure, index, position, truncation. Note that the the latter ones
1632 override former ones for identical attributes.. The new scheme means that
1633 it is possible to override any existing attribute with a relationModifier.
1634 And also that it is possible to override everything for the index rule
1635 (except the ones listed in relationModifier). No order is perfect but this
1636 one, we believe, covers more real cases.. The "always" should have been
1637 called "default", since the attributes there can be overridden with all
1640 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1641 compilation phase, but also for yaz-config --cflags output. This allows
1642 us to have public headers with Libxml2 stuff in them . It should also,
1643 eventually, make Libxml2 checks redundant in packages using YAZ, such
1646 --- 2.1.22 2006/06/15
1648 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1649 stored in uri, message and details.. Previously diagnostics were stored
1650 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1651 compatibility.. but he's probably the only one affected, so.
1653 Added support for CCL, compiled on the client side, in ZOOM-C. This
1654 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1655 input; the resulting query objects can be used for for searching with
1656 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1658 YAZ' configure searches for OpenSSL by default.
1660 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1661 SL_CTX_use_certificate_file. See
1662 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1663 for more info. Thanks to Ko van der Sloot.
1665 --- 2.1.20 2006/06/02
1667 Bug #600: SRU GET, POST support for yaz-client. Introduced
1668 command 'sru' which selects method SOAP/GET/POST.
1670 Allow missingValueAction to be specified for the sortspec string -
1671 function yaz_sort_spec. By default, the missing value action is null.
1672 Use ! to specify "abort". Use = followed by stringvalue to specify default
1675 Ensured that Present-handler (if defined) is called in GFS before any call to
1676 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1677 searchRetrieve requests.
1679 Documentation for YAZ is now based on the Docbook XML/XSLT using
1680 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1681 is no longer depending on jade/openjade or docbook-to-man scripts.
1682 PDF is no longer part of the distribution - but can optionally be
1683 made using DSSSL/jadetex or FOP.
1685 Added retrieval handling support in Generic Frontend Server to support
1686 conversion between MARC/XML as well as XSLTtransforms. See
1687 etc/yazgfs.xml for an example.
1689 Added Authentication support to Generic Frontend Server in SRU
1690 mode. Authentication using HTTP Basic is supported, as is the use
1691 of 'x-username' and 'x-password' parameters in the request itself.
1693 Added support for a new character set MARC8s identical to MARC8 except
1694 that it converts combined characters to single Unicode characters in the
1695 Latin-1 range (when possible).
1697 --- 2.1.18 2006/04/24
1699 ASN.1 compiler 0.4: generates brief Doxygen file header for
1700 generated .h/.c files.
1702 Utility yaz_iconv now supports conversion to MARC-8.
1704 New facilities for the MARC module. The reading - and writing of
1705 content are separate methods for the yaz_marc_t handle. The following
1706 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1707 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1708 format). Write functions have prefix yaz_marc_write_.. The existing
1709 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1710 available. Removed support for OAI-MARC and simplexml (not the
1711 simplexml from PHP5).
1713 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1714 to be returned for this connection.
1716 --- 2.1.16 2006/03/31
1718 Allow multiple languages and charsets to be specified with
1719 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1720 negcharset iso-8859-1,utf-8
1722 Translation of proximity nodes from CQL into PQF now works.
1724 Moved to automake 1.8, 1.9.
1726 Added function yaz_log_set_handler which allows a log handler to be
1727 installed. This handler will be called for all log messages. Output
1728 to file is also produced; but that can be disabled by passing NULL
1729 fname to yaz_log_init_file.
1731 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1733 For SRW (including GFS), accept application/soap+xml as content-type
1736 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1737 produces NO stylesheet reference even if a default stylesheet is specified
1740 --- 2.1.14 2006/03/14
1742 Updated Windows package to include yazd.dll + yazd.lib for the
1743 Development component.
1745 If the environment variable YAZ_LOG is set, then it is used as a
1746 string indicating the default level of logging to use if not
1747 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1748 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1749 used as before. So, for example, to omit warnings from YAZ logging,
1750 export YAZ_LOG=-warn
1752 cql_transform() now map structure and other attributes before indexes,
1753 so that index-specific structures and other attributes can override
1754 defaults. So now a combination of mapping specifications such as:
1756 index.dc.date = 1=date-modified 4=5
1757 does the right thing.
1759 cql_transform() now also respects the "always" mapping specification,
1760 which establishes an initial set of attributes to be used for all
1761 terms except where overridden by more specific attributes associated
1762 with the index, relation or modifier.
1764 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1765 which mode to use; one of "post", "get" or "soap" (SRW, default).
1767 Fixes for yaz_iconv routines: changed trie-based character set conversions
1768 to use only non-negative values for bit fields due to Sun's C compiler not
1769 supporting negative values.
1771 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1772 sequences where not read correctly. Fix by Rustam Usmanov.
1774 Updated win/makefile to use options, settings which makes things
1775 compile with VS C 2005.
1777 --- 2.1.12 2006/02/01
1779 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1781 In ZOOM socket code, use select instead of poll on MacOSX.
1783 ZOOM-C now support client-side compilation of CQL into RPN that is
1784 sent to the server, enabling CQL to be used against all Z39.50
1785 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1786 ZOOM_query object, and submit it using ZOOM_connection_search().
1787 The CQL-to-RPN translation uses a configuration file, the name of
1788 which must be specified in the Connection's "cqlfile" option.
1790 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1791 function, which takes as its start-term parameter a ZOOM_query object
1792 (which may have had either CQL or RPN set into it).
1795 --- 2.1.10 2005/11/29
1797 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1798 GFS to support this as well. Backend handler, bend_srw_update, does the
1799 update work. Code contributed by Ko van der Sloot.
1801 Allow retrieval of Search Result-1 information in ZOOM by the use of
1802 options that are attached to a result set. ZOOM documentation updated
1805 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1806 UTF-8 conversion. Patch by Raj Patel.
1808 Added option -m to GFS to control formatting of timestamps in log file.
1810 Added 'exit' as synonym for 'quit' in yaz-client
1812 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1813 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1814 for the new members. Patch by Ko van der Sloot.
1816 Added support for SRU POST. It is supported for content-type
1817 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1819 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1820 Instead make the library libyaz.la multi-threaded. Threading as a whole
1821 can still be disabled by configure option --disable-threads. Previosly,
1822 with older GLIBCs there were problems with MT libs under Apache. This
1823 has now been fixed a long time ago.
1825 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1828 CQL module modified to be case insensitive for relations/indexes/operations.
1830 Fixed bug in CQL transform code: incorrect value relationModifieder
1833 Added 'show all' command for yaz-client which retrieves all results
1836 Added new yaz-client, xmles, which takes a (private) OID and
1837 a document to be sent as an extended service request.
1839 Describe new yaz-client commands wait_response and set_auto_wait.
1841 Increase TCP/IP listener backlog from 3 (which I am guessing was
1842 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1843 that the socket will queue as many incoming connections as it's able
1844 to handle ongoing connections. In other words, it will never now
1845 refuse a connection that it would be able to handle merely because
1846 it's not got around to accepting() enough of the pending connections
1847 yet. This is the behaviour anyway under Linux, where the listen()
1848 argument is ignored; but not under BSD and on systems such as
1849 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1850 YAZ-based servers should now be uniform across operating systems in
1853 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1854 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1855 This allows yaz-marcdump to read large MARC batches (>2 GB).
1857 Modified all YAZ source files - except the source which is auto-generated
1858 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1861 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1862 corresponding to the existing *_setl() function. These allow option
1863 values containing arbitrary valuues.
1865 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1866 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1867 except that it returns an indicator of whether or not the sort
1868 criterion was accepted (0 for OK, -1 for invalid).
1870 --- 2.1.8 2005/06/07
1872 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1873 MARC output rather than returning "new" buffer.
1875 yaz-client warns about unknown init options.
1877 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1879 --- 2.1.6 2005/05/24
1881 Added support for SRW sort in Generic Frontend Server. Patch
1882 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1883 sortKeys - or NULL if none is provided.
1885 Fixed bug #307: It was impossible to specify indefinite/no timeout
1886 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1889 Added support for multiple languages and charsets to be specified in
1890 ZOOM. Each charset/language is separated by a blank. If negotiation is
1891 in effect in init-response, Option
1892 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1893 Code based on patch by Vasiliy Osadchuk.
1895 Fixed bug #306: infinite recursion that occurred when calling
1896 yaz_log_level_init as the first call (before other log level or
1899 Fixed bug in scan handling in front end server: if preferred-Position-In-
1900 Response was non-present, a NULL pointer referece was performed.
1902 --- 2.1.4 2005/04/26
1904 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1905 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1906 now defined for all those error codes. So instead of putting 109 in
1907 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1908 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1910 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1913 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1915 Program yaz-client now exits and produces an error message if multiple
1916 Z39.50 servers are specified on the command line (none or one allowed
1919 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1922 --- 2.1.2 2005/03/16
1924 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1926 Fixed bug #272: Preserve spacing for CCL terms.
1928 --- 2.1.0 2005/03/14
1930 Added support for virtual hosts and multiple backend servers for
1931 the YAZ frontend server. The configution is XML based and
1932 support specificition of CQL to RPN mappings and explain information.
1933 See section "Virtual Hosts" in the YAZ manual.
1935 Extended OPAC display utility. OPAC display utility renders
1936 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1937 to supplement yaz_marc_decode_wrbuf.
1939 Fixed a bug in MARC decoder that could caused it to crash for some
1940 invalid MARC records. More diagnostics and warnings where added in
1941 XML output (warnings, etc are stored in comments).
1943 --- 2.0.34 2005/02/08
1945 Fixes for UNIX domain sockets. Bug #261.
1947 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1949 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1950 Added yaz_marc_subfield_str which defines subfield lead string which is
1951 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1952 yaz_marc_endline_str which defines end of fields string used in
1953 YAZ_MARC_LINE format. Default string is newline.
1955 Experimental support for MarcXChange. This format can be produced
1956 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1957 http://www.bs.dk/standards/MarcXchange.xsd
1959 Added yaz-client commands scansize that sets maximum number of
1960 entries to be returned by scan.
1962 --- 2.0.32 2005/01/11
1964 Added support for SRW scan in yaz-client and Generic Frontend Server.
1966 * Added whereInList member to SRW Scan Term.
1968 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1970 Fixed NMEM system to return aligned blocks on the smallest boundaries
1971 that are suitably aligned for all possible types on the particular
1972 architecture YAZ is being built for.
1974 --- 2.0.30 2005/01/04
1976 Fixed numerious warnings that was issued with newer versions of GCC.
1978 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1979 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1982 Make YAZ Generic Frontend Server slightly faster.
1984 Enhance (and reduce) logging for Generic Frontend Server.
1986 Revert YAZ log system so that it flushes every write operation
1987 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1989 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1990 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1991 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1992 will effectively disable old definitions.
1994 --- 2.0.28 2004/11/09
1996 Added yaz_log_time_format which specifies log format using
1999 Added yaz_log_module_level which returns mask for a module. Value
2000 is non-zero mask a if module is enabled; zero if disabled.
2002 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2003 in include/yaz/cql.h.
2005 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2007 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2009 Fixed bug #172: RPM builds does not enable SSL.
2011 Doxyfile.in part of dist. Doxyfile generated by configure.
2013 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2014 are given and the corresponding component does not exist.
2016 Extend CCL documentation in YAZ reference. Describe r=r.
2018 --- 2.0.26 2004/10/01
2020 Fixed MARC->MARCXML conversion to properly deal with
2021 fields, subfields, indicators having non-ASCII characters.
2023 Fixed MARC->MARCXML conversion so that ASCII control characters
2024 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2027 Added YAZ GFS support for conversion from Z39.50 surrogate
2028 diagnostics to SRW surrogate diagnostics.
2030 Bug fix: YAZ GFS did not return schema in explainResponse.
2032 --- 2.0.25 2004/09/30
2034 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2035 now converts recordSchema to elementSetName as well as schema URI.
2037 Fixed bug in COMSTACK that prevented HTTP request packages from being
2040 --- 2.0.24 2004/09/29
2042 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2043 does not require white-space before and after the dash in a range, e.g.
2044 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2047 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2048 due to new GCC removing "redundant" code.
2050 Added yaz-client commands scanpos and scanstep that sets preferred
2051 position and step-size for scan.
2053 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2055 Added CCL utility ccl_qual_buf which parses one or more CCL
2056 spec lines in a buffer.
2058 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2059 of name and value - ignoring empty lines and comments.
2061 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2063 Added odr_get_element_path which returns current element path for an
2064 ODR handle. This utility is useful in error handling or user-defined
2067 Added ODR_PRINT utility odr_set_stream which is is a more generic
2068 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2069 to a write function and pointer to close function. The close function - if
2070 non-NULL - will be called during odr_destroy.
2072 Fixed bug in CCL parser where truncation char was not removed from
2073 right side when truncation=both was in effect.
2075 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2078 --- 2.0.23 2004/08/11
2080 Fix buffer overrun in CQL parser when dealing with proximity (%).
2082 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2083 to UTF-8/UCS conversion is now only based on codetables.xml.
2085 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2087 --- 2.0.22 2004/08/06
2089 Add support for more "commit changes" in ZOOM (uses Extended Services).
2091 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2094 Yet another small fix for configure of SSL.
2096 --- 2.0.21 2004/05/14
2098 Fix SSL libs for configure when --with-openssl=DIR is given.
2100 --- 2.0.20 2004/05/10
2102 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2104 SSL comstack now uses yaz.pem certificate file on server side
2105 by default. Certificate filename can be configured by calling
2106 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2108 Fix bug regarding multiple calls to ZOOM_connection_connect.
2110 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2112 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2113 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2115 ZOOM now allows inspection of X509 peer certificate for verification.
2116 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2118 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2119 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2120 as "modular" but it simplifies things.
2122 Added cs_get_peer_certificate to that returns peer X509 PEM.
2124 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2125 NULL if SSL is unavailable.
2127 Documentation about MARC decoding tools.
2129 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2131 --- 2.0.19 2004/03/30
2133 Rename CHANGELOG to NEWS to follow GNU style packing.
2135 Fix bug with missing initialization of member in init_diagnostics.
2136 This bug affects threaded version of GFS server.
2138 --- 2.0.18 2004/03/20
2140 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2143 Ensure zlib.dll is packed with Windows install.
2145 --- 2.0.17 2004/03/17
2147 Fix encoding of xsd:string to use text instead of CDATA.
2149 Fix endless loop in CQL parser with unbalanced ".
2151 Use a more compact way to store MARC-8 conversion tables.
2153 --- 2.0.16 2004/03/16 Debian only
2155 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2158 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2163 --- 2.0.15 2004/03/01
2165 Another fix for decoding of XML packed records.
2167 --- 2.0.14 2004/02/25
2169 Fixes for Chunked encoding. White space not ignored after length spec.
2171 Update NS and use default NS for SRW diagnostic elements.
2173 --- 2.0.13 2004/02/23
2175 Implement ZOOM_resultset_cache_reset which resets record cache.
2177 Implement ZOOM_resultset_sort which sorts a result set.
2179 Implement chunked HTTP transfer.
2181 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2183 --- 2.0.12 2004/02/16
2185 Added member 'schema' to bend_explain_rr structure so that backend
2186 can specify explain record identifier. Defaults to Zeerex 2.0.
2188 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2190 --- 2.0.11 2004/02/16
2192 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2195 Added init command for yaz-client which sends "extra" init request.
2197 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2198 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2200 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2202 Make ZOOM error code for "invalid query".
2204 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2206 --- 2.0.10 2004/02/05
2208 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2211 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2213 Added option -p <file> to make Generic Frontend Server to write PID file.
2215 Added option -D to put Generic Frontend Server in background on its own.
2217 Make ZOOM C recognize option "password". If unset, "pass" is used
2218 (for backwards compatibility).
2220 Fixed a bug in Generic Frontend Server that could make it crash if a
2221 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2224 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2225 Must be issued before open, in order to be in effect.
2227 --- 2.0.9-6 2004/01/12 Debian/Windows
2229 Make the SRU server more picky WRT unknown params, etc.
2231 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2233 New YAZ client command, options, that sets Z39.50 options.
2235 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2236 options from a string of tokens (one token for each option bit).
2238 Update SRW diagnostic code messages.
2240 --- 2.0.9-5 2004/01/07 Debian/Windows
2242 Handle user defined stylesheet for SRW/SRU.
2244 --- 2.0.9-4 2004/01/06 Debian/Windows
2246 Fix bug in decoding of Content-Length.
2248 --- 2.0.9-3 2004/01/06 Debian/Windows
2250 Fix a bug with decoding of XML packed records.
2252 --- 2.0.9-2 2004/01/05 Debian only
2254 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2256 Fix bug in SRW/SRU diagnostics decoding.
2258 --- 2.0.9 2004/01/05
2260 Fixed bug in Generic Frontend Server which could drop records exceeding
2261 preferred message size. Reported and fixed by Irina Dijour.
2263 Fixed calculation of package size for structured records in Generic
2264 Frontend Server. Reported and fixed by Irina Dijour.
2266 Fixed namespace for SRW/SRU diagnostics.
2268 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2270 --- 2.0.8 2003/12/22
2272 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2273 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2276 CQL changes to reflect recent changes to the specification:
2277 * Documentation talks about context sets instead of index sets.
2278 * Documentation talks about indexes instead of qualifiers.
2279 * The CQL-to-PQF transformer's configuration file now uses
2280 "index.set.name = <attributes>" instead of the old form
2281 "qualifier.set.name = <attributes>". (Both forms are still
2282 understood but the latter is deprecated.)
2283 * CQL terms with no explicit index specified are now interpreted as
2284 cql.serverChoice instead of srw.serverChoice (which of course
2285 behaves exactly the same.)
2287 --- 2.0.7 2003/12/16
2289 MARC conversion can now generate ISO2709 output in another
2290 character set. yaz-marcdump uses this facility if you invoke it
2293 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2294 functions from there can be used from C++.
2296 --- 2.0.6 2003/12/04
2298 Frontend server now transfers memory from decoded packages to stream
2301 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2302 references to show up.
2304 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2305 the ZOOM Abstract API. The older names for the same options are still
2306 also supported for the benefit of old applications.
2308 ZOOM-C supports "implementationId" and "implementationVersion" options
2309 to go along with "implementationName". These allow the user code to
2310 specify identification strings to be sent to servers.
2311 Add OID for the new ExtLite attribute set.
2313 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2314 as requested/supplid by Ere Maijala <ere@atp.fi>
2316 For generic frontend server, reverse the order of
2317 "toolkit-supplied / application-supplied" strings sent as implementationId,
2318 Name and Version. Also, remove the spaces around the slash. This brings
2319 the GFS in line with the behaviour of ZOOM-C on the client side.
2321 Add function ZOOM_scanset_display_term.
2323 yaz-client shows scan displayTerm if present.
2325 Utility yaz-iconv is now installed by default along with the man page
2328 Extend configure check for OpenSSL to use pkg-config where available (such
2331 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2332 server to specify uid/gid/mask for socket using the format
2333 unix:[user=uid,][group=gid,][umask=mask,]file=path
2334 If file= is omitted the existing format is assumed, e.g.
2336 in which case the mask is 0666 (rw for everybody).
2338 Major restructure of YAZ source. All source in libyaz is in src directory.
2339 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2340 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2342 Added man page for utility yaz-marcdump (used to be called marcdump).
2343 yaz-marcdump is installed by 'make install'.
2345 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2346 of incoming package failed.
2348 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2350 Change prototype of odr_perror: add const to message string.
2352 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2354 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2355 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2356 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2357 DNS lookup. There should not be any compatibility problems with this
2358 assuming that blocking=1 or 0 is used.
2360 Fix bad reference in UNIX comstack in function cs_addrstr.
2362 Fix for compilation on AIX.
2364 The generic front-end server (server/seshigh.c) now supports returning
2365 Init diagnostics to the client in User-information-field, in
2366 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2369 --- 2.0.4 2003/09/04
2371 Allow any CQL relation (not just all,any,exact,scr).
2373 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2374 that features the same UI.
2376 Implemented command update0 in YAZ client which is equivalent to
2377 update but uses old of Ext Update ASN.1.
2379 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2380 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2381 Previously no OID was used for this info.
2383 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2384 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2385 returns 'malformed search term' otherwise.
2387 SortResponse member resultCount now set to NULL in sort handler of
2390 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2393 Add three new utility functions for translating OIDs between various
2394 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2395 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2396 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2397 char *oid_to_dotstring(const int *oid, char *oidbuf);
2398 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2400 Reverted modifications for ES Update definition for z_IU0Update
2401 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2402 is back to YAZ 2.0.2.
2404 String value attributes for CCL parser.
2406 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2407 which their FirstSearch server returns in Init responses, sometimes
2408 carrying useful diagnostic information when Init fails. This has the
2409 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2410 "z39.50/oclcui.asn", where its definition is somewhat different from
2411 what OCLC document on their web-site, as required to interoperate with
2414 Support for anonymous authentication in yaz-client. Use the command
2417 * Fix the OID of the Index Data-local "admin" Extended Service from
2418 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2419 the 1000, which indicates a locally-defined OID, was a mistake.
2421 --- 2.0.3 2003/06/20
2423 Fix CCL directive @case handling so that it affects string match for
2424 both CCL keywords and qualifiers.
2426 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2427 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2428 Decoder has been updated with ASN.1 changes as listed in
2429 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2430 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2431 z_IUUpdate, remains unchanged.
2433 ZOOM_record_get may now return a record in a specific character set.
2434 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2435 "from" is the character set of record as returned by target. "to" is
2436 the character set to be returned. If omitted, "to" is UTF-8.
2438 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2440 New ODR utility, odr_getelement, which returns name of element for
2441 which encoding/decoding failed.
2443 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2444 in cases where a required element was omitted.
2446 Bug fix: some MARC8 sequences were not converted.
2448 New ZOOM option "step" which specifies number of records to be
2449 retrieved in one chunk. Used in conjunction with "start" and "count".
2451 SRW support for yaz-client. Use scheme http: to use it, e.g.
2454 yaz-client no longer does (un)intelligent character set conversions
2455 by default. Can be enabled with charset and marc_charset commands.
2457 xmalloc trace fix for 64-bit systems such as DEC alpha.
2459 Solaris 2.6 compile fix.
2461 New function, cql_strerror() translates SRW error codes, as returned
2462 by cql_transform_error(), into human-readable English strings. Used
2463 in yaz-client diagnostics when appropriate.
2465 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2466 converts it into a type-1 query which is sent to the server. This
2467 makes CQL available for use with all Z-servers, as opposed to the tiny
2468 minority that can handle CQL queries themselves.
2470 --- 2.0.2 2003/04/28
2472 New Debian package layout similar to the Redhat Package layout.
2474 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2475 and search result respectively.
2477 --- 2.0.1 2003/04/25
2479 Redhat package is now several packages: libyaz (runtime libraries),
2480 libyaz-devel (development and documentation, and yaz (utility programs).
2481 Package spec file by Morten Bogeskov.
2483 New member 'schema' in struct bend_fetch_rr which the name of requested
2484 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2485 handler MAY set this to reflect the schema of the returned record.
2487 New member 'display_term' in struct scan_entry. GFS now sets member entries
2488 and allocates scan entries to be filled by user scan handler. In previous
2489 version, entries member was allocated by the scan handler. That still works,
2490 but the GFS will ignore member display_term - assuming it was NOT set by
2491 the handler. The fact that the GFS now allocates the entries both allows
2492 for new members and makes a scan handler easier to write.
2494 Fix CQL lex buffer overflow.
2496 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2497 SRU default recordPacking is string.
2499 SRU protocol support for frontend server.
2501 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2503 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2505 Added scan for the ZOOM shell (zoomsh).
2509 * String Identifers for Schemas (Amendment 5).
2510 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2511 Old definition for schema
2512 Odr_oid *schema; /* OPT */
2517 Z_InternationalString *uri;
2518 #define Z_Schema_oid 1
2519 #define Z_Schema_uri 2
2522 * resultCount parameter to Sort Response (Amendment 1).
2523 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2525 Support for SRW 1.0 over HTTP. This is an optional feature and
2526 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2529 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2530 on the same port. SRW SearchRetrieveRequests are mapped
2531 to bend_init,bend_search,bend_fetch,bend_close.
2533 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2535 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2536 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2538 ZOOM connections are SRW based if schem http is used for hostname
2539 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2540 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2542 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2543 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2544 distance=n, order=true/false, relation=le, prox unit=word. If
2545 n is omitted, distance 1 is used.
2547 Fixed problem with C compiler include path in wrong order.
2549 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2550 on Solaris. Patch from Ko van der Sloot.
2552 New MARC decode API. All new functions operate on a yaz_marc_t
2553 handle. The most important new functions are: yaz_marc_create,
2554 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2555 decode and destroy respectively. Decoder can produce formats
2556 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2557 include/yaz/marcdisp.h.
2559 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2560 to UTF-8, UCS-32, wchar_t or Latin-1.
2562 * Prototypes for yaz_iconv_-functions moved to separate header
2563 include/yaz/yaz-iconv.h.
2565 Make a few private functions 'static' in unix.c. This prevents
2566 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2568 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2569 are set when Init Response is received.
2571 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2572 but returns diagnostic set as well.
2574 New function yaz_strerror which is a portable wrapper for
2575 strerror/strerror_r/GetLastMessage.
2577 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2578 is returned for MARC. If type is "oai", then OAI MARC is returned.
2580 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2583 --- 1.9.2 2002/11/26
2585 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2587 Fix bad race conditions on SIGTERM and terminate gracefully in
2590 Move retrieval (data1) module to Zebra since nobody seems to be
2593 Add GRS-1 render for ZOOM using same format as yaz-client.
2595 --- 1.9.1 2002/10/05
2597 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2599 Fix broken ESpec handling in data1 module.
2601 SGML reader parses comments and makes them part of the data1 tree.
2603 Added several type casts so that YAZ compiles as C++ code.
2605 ZOOM didn't handle PDU encoding failures properly.
2607 Added more Bib-1 diagnostics (approved extensions).
2609 GNU configure: better check for iconv.
2611 More portable use of accept, getpeername. Check for socklen_t. Use
2612 int/size_t if socklen_t is not defined.
2616 PQF parser rejects bad queries - including those with extra
2617 characters in them. PQF parser used to silently ignore that.
2618 Cleaner API for PQF added, which allows you to get detailed
2619 error information for bad queries (see yaz/pquery.h).
2621 Fixed bug in ZOOM_record_get for type "database".
2623 Implemented mini iconv library supporting conversions between
2624 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2626 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2628 --- 1.8.9 2002/08/20
2630 Fixed ZOOM C record cache so that preferredRecordSyntax and
2631 elementSetName is used to check for already fetched records.
2633 --- 1.8.8 2002/08/02
2635 Added three members in bend_initrequest structure to facilitate
2636 character set negotiation.
2638 Fixed a bug in frontend server that could cause indefinite
2639 loops under rare conditions.
2641 Revised character set utilities (charneg.h) so that encoding
2642 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2644 For PQF, directive @term <type> sets term type for Scan/Search.
2645 Here <type> is general, string, numeric, null. The term type
2646 is inherited - just like @attr.
2648 New call odr_set_charset that sets character set conversion for
2649 international-strings on a ODR stream. Prototype is:
2650 int odr_set_charset(ODR o, const char *to, const char *from);
2651 The InternationalString is still represented as C string in YAZ
2652 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2653 won't). On the protocol level, you can use any encoding.
2655 Support for UNIX sockets in ZOOM.
2657 Solaris recv sometimes returns errno == ENOENT. It is treated as
2658 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2660 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2661 both client and server. Code by Morten Bogeskov.
2663 --- 1.8.7 2002/05/22
2665 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2666 that they can be used directly from Visual Basic. You must recompile
2667 your windows APP if you're using ZOOM.
2669 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2670 Commands "lang" and "charset" sets language and character set respectively.
2671 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2672 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2674 Attributes from multiple CCL fields may be OR'ed rather than merged
2675 using directive "@field or". Fields are still merged by default -
2676 equivalent to "@field merge".
2678 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2681 Fixed bug in zget for parameter ExtendedServicesResponse.
2685 --- 1.8.6 2002/03/25
2687 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2689 Client displays USR.1:SearchResult-1 (hits per term).
2691 Additional Search Info for search in Generic Frontend Server.
2693 Fixed CCL parsing of "field=s".
2695 WIN32 installer - using the excellent NSIS software from nullsoft.
2697 Fixed CCL parsing of "field = - <number>".
2699 Added function yaz_marc_decode that decodes MARC for line mode
2700 display or XML (similar to that used by JZKit).
2702 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2703 Z39.50. But ISO/ILL was, however.
2705 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2706 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2708 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2709 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2711 --- 1.8.5 2002/02/03
2713 New YAZ client features: Command completion and new commands:
2714 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2715 Code provided by Jacob Poulsen.
2717 New call oid_trav, that visits all registered OIDs via callback.
2719 Function ZOOM_record_get now returns const char pointer rather than
2720 void pointer. It saves a lot of type casts.
2722 For YAZ client, command "auth" now allows you to set authentication
2723 in IdPass style. It is enabled when three tokens are given - order
2724 is user, group and password.
2726 Fix memory leaks in MARC record handling for ZOOM.
2728 New option for YAZ client, -k <kilobytes> that sets
2729 maximum record size. Similar to -k option for generic frontend
2730 server and yaz-ztest.
2732 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2734 Prefix query parser reports "fail" when bad attribute set is given.
2736 Fix in MARC decoder. Proximity logging. Fix for attribute set
2737 in scan handler for server. Patches by Shigeru Ishida.
2739 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2742 Configure option --with-openssl=<dir> now works when a directory is
2743 specified. Patch provided by Morten Bogeskov.
2745 New option for YAZ client, -u <auth>, that sets authentication.
2747 ZOOM fix: error information was sometimes "missing", since error
2748 was cleared/reset too when it shouldn't.
2750 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2752 --- 1.8.4 2002/01/04
2754 Scan for ZOOM API. New object ZOOM_scanset. New functions
2755 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2756 ZOOM_scanset_destroy.
2758 New ZOOM function, ZOOM_connection_last_event, that returns type
2759 of last event (such as "receive data", "send data", "apdu received",
2762 New ZOOM option, schema, that specifies schema for retrieval.
2764 New CCL feature. Qualifiers can be aliases for one or more
2765 other qualifiers (if more than one is given, OR is used).
2767 ZOOM uses named result sets if target supports it.
2769 Two new YAZ client commands: . (dot, which sources a script of YAZ
2770 client commands), and ! (to execute shell command.). Implemented
2773 Working on Debian packages.
2775 --- 1.8.3 2001/11/19
2777 YAZ client enables named result sets only if target supports it.
2779 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2781 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2782 with key="host" to get same result.
2784 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2785 Function Z3950_resultset_record(s) returns references to records
2786 "owned" by resultset. To become owner use Z3950_record_clone.
2788 Function z_ext_record handles Extended Services. Thanks to
2791 --- 1.8.2 2001/11/12
2793 CCL Parser fix: ignore token comma when dealing with and-lists.
2795 Documentation updates for COMSTACK.
2797 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2798 Changed prototype Z3950_records. For some functions, int parameters
2799 were changed to size_t.
2801 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2804 New MARC decode/display function, marc_display_exl, which properly rejects
2805 non-ISO2709 records. YAZ client uses it.
2807 --- 1.8.1 2001/10/29
2809 Fix bug: local attribute set wasn't set correctly in PQF strings.
2813 * Old Z39.50 codecs no longer supported.
2815 Added ZOOM C binding. See http://zoom.z3950.org/
2817 Renamed states for COMSTACKs to avoid confusion with events.
2819 Implemented cs_look and proper cs_rcvconnect.
2821 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2823 Configure detects POSIX threads on OpenBSD.
2825 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2826 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2828 When error is returned from present handler, non-surrogate diagnostic
2829 is returned in present response (and fetch handler is no longer called).
2831 * Minor adjustments to pquery parser (PQF). Token characters may be
2832 escaped by using backslash (C-style).
2834 PQF parser allows string attribute values to be specified. For @attr,
2835 non-numeric characters after the equal-sign are treated as strings
2836 (e.g. @attr 9=title).
2838 CCL trunction character may be defined (@truncation in file)
2840 * function zget_ExtendedServicesRequest sets waitAction to
2841 waitIfPossible (was wait).
2843 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2846 CCL operator names may be set in field definition files (CCL_bibset).
2847 See ccl/bib1 for an example.
2849 Fixes in ASN.1 compiler for C++ compatibility.
2851 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2852 and "op_or" to avoid conflict with C++.
2854 Fixed problem with GNU readline detection on Redhat 7.0.
2856 Added step-size for Scan backend handler.
2858 Fixed bug that made the frontend server crash when no attribute
2859 set was specified for scan.
2861 Front-end server automatically switches to original working directory
2862 when installed as an NT service. Previously -w had to be specified to
2865 Added extended attributes for retrieval module (data1), so that data1
2866 records carry d1_readXML/SGML attributes. d1_read also supports
2867 null-data rules ( <tag/>)
2869 On UNIX when POSIX threads are available, a separate library libyazthread
2870 is created. Programmers should link with that library and the yaz library
2871 when using threads. The reason for the split was that some applications
2872 on Linux, such as Apache, doesn't work well when using shared objects that
2875 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2876 (or any frontend server) in SSL mode by specifying ssl: followed by
2877 address. Only tested on UNIX.
2879 Added feature for CCL module. Virtual structure s=al or s=ol generates
2880 and-list and or-list respectively instead of phrase search.
2884 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2885 log_mask_str. This was done to avoid name conflicts with other libraries
2886 (such as other PHP extensions).
2888 Added raw OID member for preferred record syntax (request_format_raw)
2889 and returned record syntax (output_format_raw) for backend fetch method.
2891 Config file yaz-config now accepts options so that it returns specific
2892 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2894 Shared library support for UNIX using GNU libtool.
2896 * Modified backend interface. Request/Response struct's replaced by
2897 one read/write C struct. For example bend_fetchrequest and
2898 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2899 Every handler - even search has to be registered in bend_init
2900 handler. This means that the YAZ library no longer refers to
2901 external functions and it makes it possible to make the whole
2902 thing a single DLL/SO.
2904 Added Segment handler for backend server.
2906 Added Zmbol/Zebra administrative functions to YAZ client.
2908 Threaded frontend server on UNIX (when POSIX Threads are available).
2909 Starting the server with option -T enables multi-threading.
2913 Added configure option --enable-comp/disable-comp to control use
2914 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2915 located in sub directory asn.
2917 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2918 in ${exec_prefix}/bin along with the other programs yaz-client and
2921 GNU automake used to maintain makefiles.
2923 Added several OID's.
2925 Changed retrieval module so that we can load records with no abstract
2926 syntax defined. Tagpaths in these records are fully composed of string
2929 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2933 On UNIX, the generated makefile now supports a proper 'make install'.
2934 The prefix can be set via GNU configure to set the install location
2935 (default is /usr/local).
2937 * YAZ programs client and ztest were renamed to yaz-client and
2938 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2939 locations, such as /usr/bin,/usr/local/bin,etc.
2941 * YAZ Header files were moved from include to include/yaz. YAZ Header
2942 files are referred to as include <yaz/log.h> rather than <log.h>.
2943 The YAZ include path (-I ..) is therefore the same as before. Programmers
2944 should update their #include statements or use -Ipath/include/yaz
2945 instead. The main motivation for doing this change is that YAZ header files
2946 can be installed in "standard" locations /usr/include,/usr/local/include
2947 without introducing conflicts, since ALL YAZ header files are stored
2948 in subdirectory yaz (under /usr/include for example).
2950 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2951 rather than project/workspace files. We switched because project files
2952 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2955 Changed name of logging function, logf, to yaz_log, to prevent name
2956 clash with some math-log functions. The YAZ header log.h defines logf
2957 to yaz_log (#define) so there should be no incompatibilities by this
2960 Added bend_start/bend_stop handlers for server. These handler are
2961 called on start/stop of server. For windows they are called whenever
2962 a service is started/stopped.
2964 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2965 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2966 in util/yc.tcl. The auto-generated C code structures are, in a few
2967 cases, incompatible with the old decoders. There are differences in the
2968 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2969 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2970 The preprocessor variable ASN_COMPILED is defined when the compiled
2971 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2972 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2973 wish to use the old encoders/decoders you can specify --disable-yc
2976 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2977 version so that it supports both new - and old version of DB Update
2979 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2980 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2981 change. The name parameter can be set to 0 in which no name is specified
2982 for the construction. The macros odr_implicit and odr_explicit sets name
2983 parameter to zero for the construction involved. New macros
2984 odr_implicit_tag and odr_explicit_tag are similar to the others,
2985 except that a name parameter is added. For programmers' that don't use
2986 ODR they probably only need to change the call to z_APDU and z_External.
2988 Added access control facility by interfacing the TCP wrapper library.
2989 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2990 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2991 name of the daemon and enables the access control as specified in
2992 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2994 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2995 den Dool <H.M.vdnDool@kub.nl>.
2997 Added reference ID parameter to most functions in server API - refer
2998 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3000 Changed name of ccl library to libccl.a (was ccl.a).
3002 Fixed bug in decoder for Explain (Category TargetInfo).
3004 Added support for GNU readline in client. Thanks to Jacob Poulsen
3005 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3007 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3008 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3009 IMPLEMENTATION! This change was made to the development version before
3010 the ZIG decided to retract the amendment. If any users MUST be
3011 compatible with the original Update definition, PLEASE CONTACT US, and
3012 we will include a separate definition corresponding to the old Update
3013 ES. Note that because of the change to the ASN.1 of the
3014 TaskPackageRecordStructure we cannot define a single structure that
3015 will support both versions.
3017 * Added const modifier to buffer parameter for some ODR/BER encoding
3018 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3019 completeWAIS, odr_dumpBER.
3021 Fixed bug in client.c which caused a crash when a scanResponse didn't
3022 contain positionOfTerm.
3024 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3025 * will cause an error in a client if a non-YAZ target sends both a
3026 * list of Scan entries and non-surrogate diagnostics.
3028 Retrieval module enhancements. Tag sets may be typed in the reference
3029 to it. From the .abs-file the "tagset" directive takes a third optional
3030 integer type for the tag set referenced. From a .tag-file the "include"
3031 directive takes a third optional type as well. The old "type" directive
3032 in the tag set itself is still recognized but acts as the default type
3035 Backend interface change. Individual Scan terms returned from bend_scan
3036 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3037 in include/backend.h.
3039 Retrieval module enhancements. Multiple tag sets and attribute sets may
3040 be specified in abstract syntax specs. Revised the error/warning for
3041 logging messages reported by the retrieval module when reading the
3044 Object Identifier system (oid_..) changed. The API is backwards
3045 compatible but the oid-routines now allocates new OID's when needed.
3046 Raw OID's may be specified in oid_getvalbyname.
3048 YAZ now uses GNU configure to generate Makefile(s).
3050 * Minor changes in some of the member names of DeleteResultSetRequest and
3051 DeleteResultSetResponse. See include/proto.h.
3053 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3054 and added member 'languages' in TargetInfo (which was missing).
3056 Changed the way attribute sets are handled in the retrieval
3057 module. These are now cached, just like the abstract syntaxes
3060 Changed YAZ so that it links with compiled ASN.1.
3062 Added Explain-schema definitions and mapping routines. The following
3063 Explain categories have been implemented: AttributeDetails,
3064 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3066 Fixed minor bug in Windows version of Server Library.
3068 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3070 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3072 Added EXTERNAL: UNIverse Resource Report (non-standard).
3074 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3075 ENUMERATED and SET OF.
3077 * Added 'const' to some of the char pointer arguments for the
3078 functions, data1_read_node, data1_getelementbytagname,
3079 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3082 Fixed bug in data1_insert_taggeddata - the last_child member of
3083 parent wasn't initialised.
3085 * Changed data1_read_record and data1_read_node so that the supplied
3086 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3087 doesn't refer to any parts of the "SGML"-buffer.
3089 Fixed bug in server library (Windows version of statserv_remove).
3091 * Changed code so that it compiles as C++. The type definition
3092 of Odr_fun which is a member of Odr_arm was changed. The result is,
3093 that an explicit typecast is needed for the fun pointer when
3094 using Odr_arm - as in:
3095 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3097 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3099 Implemented the new structured date and time definition as approved
3100 by the ZIG. Added schemaId element to the specificTag in Espec-1
3101 (also approved at the last ZIG). Thanks to RVDM.
3103 Added some Object identifiers (RVDM).
3105 Changed the Update Extended Service (RVDM).
3107 Added command "refid" to client which specifies referenceId for
3108 the following requests.
3110 Implemented extended service handling for server. See ztest.c
3111 for an example as well as backend.h. New handlers are registerd
3112 in the Init handler.
3114 * Changed interface for sort in server.
3116 Added new members to statserv_options_block. It allows a server
3117 to read options from another source than just the command line. Thanks
3118 to Charles Woodfield.
3120 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3121 renamed to zboolean. Some C++ compilers complained about the name.
3123 Minor changes to gils.abs. Added index 's' (sort) on title
3124 and date/time-last-modified.
3126 --- 1.4pl2 1998/1/30
3128 Fixed bug in server library regarding inetd mode (-i). This bug
3129 was introduced by release 1.4.
3131 --- 1.4pl1 1998/1/29
3133 Added sort facility in client and backend server interface.
3135 Fixed problem with dependencies in Makefile(s).
3137 Fixed bugs for encoders/decoders of extended services and
3140 Implemented sub-tree feature for schemas. Sub-trees are
3141 referenced in *.abs-files. See explain.abs for an example
3142 of the use of this feature.
3144 Modified bib1.att; local attributes for ANY didn't include
3145 ANY itself (only affects use of the retrieval module).
3147 Fixed bug in plain SGML reader in function data1_read_node:
3148 tags with prefix "var" was incorrectly interpreted as variants.
3150 Added feature "sub-schemas" to enable references to - and definitions
3151 of - group of elements.
3153 * Removed member parent from type data1_element (in data1.h).
3155 Implemented function odr_nullval() that returns the value of
3158 * Removed member num_children from data1_node (in data1.h).
3160 Made NT service interface part of the server library. The
3161 function statserv_main uses the NT service when required and
3162 calls the statserv_start / statserv_close routines.
3164 Routine zget_SearchRequest and zget_PresentRequest fills
3165 resultSetName/Id member with "default" instead of "Default".
3167 Fixed memory leak in server. Request queue member wasn't freed.
3169 Fixed nmem_exit so that memory is freed.
3173 Revised the CCL parser utility to be thread safe.
3175 Added function, oid_ent_to_oid, to replace the function
3176 oid_getoidbyent, which is not thread safe.
3178 * Added nmem_init and nmem_exit to initialize and release
3179 NMEM resources. Function nmem_init should be called once in the
3180 initial thread before NMEM/ODR is used. statserv.c and client.c
3181 have been changed accordingly. The change was necessary to make
3182 NMEM thread safe. The NMEM memory pool is shared amongst threads
3183 in a process. Unix-based applications will still work fine without
3186 Added NT Services interface for the the Z39.50 (statserv) Server.
3187 Refer to the ztest.c source on the usage.
3189 Windows 95/NT port using MSVC5.0. Project files are included in the
3192 * Defined new 'global' handle for the retrieval (data1) system. The
3193 new handled, data1_handle, describes the state of the data1 system.
3194 This handle is passed as first argument to virtually all
3195 data1 related routines. The functions data1_create and data1_destroy
3196 creates and destroys a data1 handle respectively.
3198 Added ODR encode stream member to all backend request structures
3199 init, search, scan etc. This stream should be used to allocate all
3200 memory used for the response when thread safe operation is needed.
3202 Changed the comstack utility, cs_addstr, to be thread safe. The
3203 returned hostname string returned by the function is now part the
3206 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3207 function. The cs_straddr takes a COMSTACK handle as argument, so this
3208 function must be used after cs_create and before bind/connect.
3209 This function is thread safe.
3211 Moved test server to 'ztest' directory - generic server code still
3212 in 'server' directory.
3214 Made prefix query (pquery.c) utility thread safe.
3216 Added new function modifier YAZ_EXPORT to 'export' public DLL
3217 functions when using windows (see include/yconfig.h).
3219 Added definitions to the OID database (util/oid.c) (RVDM).
3221 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3223 Added call to ccl_rpn_delete in client program.
3225 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3226 release of RPN structure.
3228 Added support for C++, headers uses extern "C" for public definitions.
3229 With input from RVDM.
3231 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3232 Thanks to Ronald van der Meer (RVDM).
3234 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3236 Added support for private extensions to the OID database
3237 (oid_setprivateoids()). Thanks to RVDM.
3239 Added optional, physical ANY (key replication)
3241 Fixed null-reference problem in GRS-1 output filter.
3243 Proximity operator added to Prefix Query Format (PQF).
3245 In test client command "base" accepts multiple databases.
3247 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3251 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3253 Smallish bug-fixes in the new encoders/decoders (explain).
3255 Bug fixed in DeleteRequest.
3257 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3259 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3261 Added SOIF syntax (using private OID for now) to retrieval module and client.
3263 Added Update extended service.
3265 Added SearchResult-1 additional info structure.
3267 Added optional CCL (ISO8777) interpreter as separate module. Available
3270 --- 1.2 1996/6/10 (1st anniversary release)
3272 Added Summary record syntax. Lightly tested.
3274 Added OPAC record syntax. Untested.
3276 Added ResourceReport service encoders/decoders. Untested.
3278 Fixed bug in z_Unit - wrong tagging on unitSystem.
3280 Fixed bug in the DiagRecs decoder.
3282 Added options for max PDU size and session timeout to frontend-server.
3284 Added documentation of query-language parsers and other supporting utilities.
3286 [frontend-server] Added Attribute set to the bend_scanrequest API.
3288 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3289 surrogate diagnostics were generated.
3291 [retrieval] Allow multiple local values for attribute.
3293 [retrieval] Allow multiple attributes per element in .abs files. index type.
3295 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3297 --- 1.1pl2 1996/4/10
3299 Minor changes, mostly specific to Zebra's requirements (retrieval)
3303 Repaired bug in frontend server when running multiple listening
3304 endpoints in dynamic mode.
3306 z_External() now won't break if a known, ASN.1 value comes encapsulated
3307 in an octet-string. The value will pass through unmodified in an Odr_oct.
3309 Added a bit of code to the demo client to decode & display
3310 ASN.1-structured records represented in the octet-aligned branch of
3311 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3313 Added z_ext_getentbyref() to the ASN module. Doc updated.
3315 * Completed the SCAN definition in the ASN module. This may break SCAN
3316 code based on older YAZ-versions at compile-time. The fix is easy -
3319 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3320 under the SCAN definition. Remember to initialize this, server-people.
3322 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3323 that this does not extend to ODR and ASN.
3325 Comstack allows insertion of established socket (primarily for
3326 inetd-operation of servers). Doc updated.
3328 Front-end server can now start from the inetd in TCP mode. Doc
3331 --- 1.0pl4 1996/1/24
3335 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3336 the rank and record number.
3338 Adjustments to the frontend server.
3340 Fixed diagnostic BER dumper. It ignored the file argument.
3344 Various changes to retrieval module.
3346 Changed the union discriminators of the protocol files from enums to
3347 ints paired with #defines.
3349 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3352 *Changed operator in the RPN structure to 'roperator', again to avoid a
3355 Fixed problems in Explain decoders/encoders.
3357 --- 1.0pl2 1995/12/6
3359 Memory bug in log module fixed.
3361 --- 1.0pl1 1995/12/5
3363 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3365 Bug in Explain DatabaseInfo module fixed.
3367 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3371 The shift to v1.0 signals that we now consider the *core* functionality
3372 of YAZ reasonably stable (the core being more or less equivalent to
3373 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3374 tested (Explain not at all - though that will happen soonish).
3376 Minor changes to code to support Windows port.
3378 Various minor changes after we're getting to use GRS-1 & co. more.
3380 Added Espec-1 format.
3382 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3383 of the protocol and it cannot be selected when encoding (maps into 'string'
3384 when decoding). Needed to talk to some servers.
3386 Demo client can request simple element set names.
3388 Added Diagnostic Format encoders/decoders.
3390 Added simple Close handling to frontend server (no hooks for resource
3391 reporting yet), and demonstration client.
3393 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3395 --- 1.0b3 1995/08/24
3397 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3398 handled incorrectly when records were requested in the searchResponse. This
3399 will only affect you if you use the frontend-server.
3401 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3402 Test-client will ask for and print GRS1. Ztest will return dummy records
3405 Added Explain encoders/decoders to the service-level API. Untested.
3407 Added Extended Services: Item Order encoders and decoders to the Service-
3408 level API. Untested. We could use a recent copy of the pertinent bits
3409 of the ILL protocol to add those bits.
3411 Added diagnostic format 1 encoders/decoders to the service-level API.
3414 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3415 odr_cons.c, which causes a more correct output.
3417 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3418 was always set to 0 when no records were requested in the searchRequest.
3420 * Added better external-handling. This shouldn't harm old code that
3421 *encodes* externals. It can break code that looks for a
3422 'single-ASN1-type' representation, since those types that are known
3423 are now decoded immediately. Look at the SUTRS sample code in
3424 seshigh.c and client.c. Documentation updated.
3426 Handling of structured records in bend_fetchresponse. Length -1 marks
3427 structured record, type is deduced from format field.
3429 --- 1.0b2 1995/06/27
3430 Fairly quick maintenance release to add SUTRS support.
3432 Fixed handling of SUTRS records in the demonstration client.
3434 * Added format field to the bend_fetchrequest and bend_fetchresponce
3435 structures of the backend API (frontend server). When the record is
3436 returned, the value of the format field is mapped to an OID. The
3437 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3438 of the record. The special value VAL_NONE in the bend_request means
3439 that no specific format was requested by the client. Documentation
3440 updated accordingly. Test server (ztest) will return a fixed dummy
3441 SUTRS record if your client requests SUTRS.
3443 Documentation updated accordingly.
3445 You can now set external libraries and RANLIB support in the top-level
3449 First public release.
