3 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
5 OPACXML: sync spelling of availabilityDate in XML to that of Schema
6 opaxxml.xsd. The schema had the correct spelling of this member always.
7 The ASN.1 was mis-spelled and still is (API change) - we are
8 not changing this. However, the OPAC to XML conversion had yet
11 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
14 New function, z_ext_record_oid_nmem, which is similar to
15 z_ext_record_oid but takes NMEM rather than ODR
19 ICU: New conversion element 'join' which joins tokens into one
20 with a custom character given by rule attribute.
24 New GFS search member: present_number. This is a hint to the
25 search handler how many records are going to be fetched immediately
26 following search. There's no guarantee that it's going to be the case,
27 since it depends on hit count (for Z39.50 piggyback) and whether errors
30 Make a few functions static (private). The functions getbyte_stream,
31 ungetbyte_stream and yaz_gets are now private. They were never declared
34 yaz-marcdump: exit(5) for serious decoding errors
36 ISO2709 decoding: be more picky WRT header
38 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
39 was only used as to indicate that next-result-set-position should be
41 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
42 Based on patch from Ashley Sanders.
44 Make some functions static/private in PQF parsing. Those functions were
45 never declared in a public header and so should not be in use by
46 applications based on YAZ.
50 ZOOM: special options to control APDU logging.
51 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
52 logging of APDUs until "saveAPDU" option is set again. If logging is
53 already enabled the effect is that current APDU buffer is cleared.
54 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
55 logging (default behavior on new connection).
56 The APDUs sent/received can be obtained by using
57 Using ZOOM_connection_option_get(c, "APDU") or
58 ZOOM_connection_option_getl(c, "APDU", &l).
60 GFS: relay implementation_version from backend
61 From 3.0.40 and later, implementation_version from backend was
62 not used in init response at all.
66 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
67 mode at all. Probably never did.
69 Make a new version of ztest.pem that, at least, is not expired.
73 Fix description of CCL directive 'case'.
75 More tight checking of form arguments (yaz_uri_to_array). Makes
76 YAZ better at rejecting big and/or bad POSTs.
78 SRU decoding does not report more than up to 10 invalid arguments.
80 rpn2cql: less quotes in generated terms. Semantics unchanged, but
81 it's prettier this way.
85 New utility yaz_decode_init_diag. Defined in proto.h.
87 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
88 given for unix local socket.
89 The COMSTACK string for doing so is:
92 unix:/myfile:tcp:localhost:9999/mybase
93 unix:/myfile:localhost:9999/mybase
94 unix:/myfile:http://fakehost/mybase
96 debian: Use dpkg-buildflags in build process.
100 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
101 global's SRU service uses a recordPosition scheme starting from zero.
102 First record's position should be one
103 according to the standard.
105 --- 4.2.42 2012/10/18
107 Allow more namespaces for SRU. This is to allow, for example, an
108 incorrect namespace returned from server
109 http://services.igi-global.com/sru .
111 Minor fixes for compilation on Windows.
113 --- 4.2.41 2012/10/11
115 daemon: log total number of bad signals from child on stop so that it
116 is more easy to spot problems with child worker processes.
118 retrieval: empty backend name attribute omits element set
119 from being used in retrieval.
121 --- 4.2.40 2012/10/04
123 Implement Solr sort strategy "solr", similar to sru11 sorting.
124 This will implement the correct parameters on Solr requst to do
127 --- 4.2.39 2012/09/28
129 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
132 MARC: Extra/missing indicator handled for MARCXML.
133 The indicator length is given in header and is the same for the
134 whole record. If attributes ind1, ind2 are missing, then content
135 character defaults to blank. Extra indicator attributes (beyond)
136 indicator length are treated as an error.
138 Reformat: delete trailing whitespace
140 --- 4.2.38 2012/09/17
142 MARC: fix non-ASCII characters for leader. This is to ensure we can
143 generate XML in UTF-8.
145 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
146 in one node with structure word.
148 --- 4.2.37 2012/09/04
150 yaz-json-parse: JSON output may be pretty printed by using option
153 Increase default value of max message for Z39.50 Init for GFS, ZOOM
154 and yaz-client. Old value was 1 MB. New value is 64 MB.
156 --- 4.2.36 2012/08/22
158 yaz-client: don't display bogus records from SRU servers. Some SRU servers
159 return more records than given by *maximumRecords*. Skipping those in
162 record_render: simplify buffer return handling and fix at least one bad
163 memory reference, that broke the test_embed_record sometimes.
165 Allow http://user:pass@host notation for yaz_url_exec.
167 zoomsh: allow shell command to be executed. Via the system(3) call.
169 yaz_poll: Allow num_fds == 0
171 yaz-client: fix bad encoding of "itemorder item". The itemorder
172 item <no> - command forgot to use length of encoded Item Request
173 package. Error present since YAZ 3.
175 yaz-ztest: fix bad usage of session handle. Bug was introduced when
176 result sets were saved (271a9c83).
178 SRU recordPacking: guess record packing in response rather than looking
179 at the recordPacking element which, OF COURSE, changed semantics in SRU
182 Decode SRU 2.0 responses. The official namespace for responses, according
183 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
184 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
185 nature.com's server, however, usee namespace
186 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
187 we are now using a glob-expr to match up the namespace. ZOOM C and
188 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
189 I can not find a single real example showing the "real" namespace in
190 the documentation from OASIS. The namespace for requests is different
191 from responses, but this is not added to YAZ yet, when we don't encode
194 --- 4.2.35 2012/06/26
196 zoom/record_render: add support for Base64 decoding fo MARC records
197 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
198 which will decode base64 + ISO2709 marc-8 encoded material from text node
201 --- 4.2.34 2012/06/07
203 Add missing definitions ZOOM_resultset_get_facet_field_by_index
204 and ZOOM_resultset_facets_names.
206 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
209 Change APDU dump printing to avoid long leading blanks. For levels 16
210 or larger the level is shown and the indentation is truncated but
211 recursed with modula 8. This makes it still reasonable easy to read
212 - even for nested BER dumps.
214 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
215 return 0 (incomplete package) in case where the BER package was
216 considered too nested (return value of -2).
218 dumpber: lines of level 15 are not indented further. Two spaces per
219 indentation; indentation 15 or more is indented to a fixed indentation
220 and augmented with a level=<no> indication.
222 zoomsh: increase max size of command+args
224 GFS: No limit in RPN buf size in CQL to RPN conversion.
226 --- 4.2.33 2012/05/09
228 New function for daemon utility, yaz_daemon_stop .
230 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
232 --- 4.2.32 2012/04/25
234 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
235 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
237 --- 4.2.31 2012/04/23
239 YAZ daemon utility relays SIGUSR1 to child process.
241 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
242 would result in en empty database list - which in turn would result in
243 encoding failure for search.
245 Fix reading beyond string in yaz_sort_spec.
247 --- 4.2.30 2012/04/11
249 Add two new SRU diagnostics:
250 236: Access to specified database denied
251 1015: Init/AC: Maximum number of simultaneous sessions for Userid
253 Document the very useful ZOOM-C option "apdulog".
255 CQL to RPN: term may be passed through verbatim. This is enabled with
256 truncation.cql . The assumption being that the term is already CQL.
258 --- 4.2.29 2012/03/20
260 record_conv: leader spec may be given for marc element.
261 The leader spec is given as attribute leaderspec for element marc.
262 For example to convert a MARC21 record from MARC-8 to UTF-8:
263 <marc inputformat="marc" outputformat="marc"
264 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
266 record_conv: allow user-XSLT params. For example:
267 <xslt stylesheet="MARC21slim2DC.xsl">
268 <param name="myparameter" value="myvalue"/>
269 <param name="otherparameter" value="othervalue"/>
272 record_conv: fix error handling for missing marc charsets.
274 CQL: fix extra terms in wrong order.
276 --- 4.2.28 2012/03/06
278 record_conv: modify new API for conversion types. The conversion types
279 may be passed in new functions yaz_record_conv_configure_t and
280 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
282 Avoid mixed statement/variable declare; fixes compilation with Visual
285 --- 4.2.27 2012/02/28
287 Add non-standard SRU diagnostic: 235: "Database does not exist".
288 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
289 Update SRU to Bib-1 diagnostic maps accordingly.
291 CCL: add two new diagnostics for unsupported masking. The new
292 diagnostics are: "Embedded truncation not supported" and
293 "Single charcacter mask not supported".
295 --- 4.2.26 2012/02/23
297 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
299 --- 4.2.25 2012/01/11
301 Build YAZ for Ubuntu Oneiric.
303 CCL: allow parantheses for proximity operands. For example CCL query
304 (a) % (b) is now allowed.
306 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
307 marked dead, rather then being destroyed. If not, the session memory is
308 being free'd before the search/scan handler is finished. Also destroy
309 'request' memory in request_release rather than in various places,
310 which resulted in leaks from time to time.
312 --- 4.2.24 2011/12/21
314 cql_sortby_to_sortkeys: honor sort prefix.
316 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
317 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
318 The rpn2cql family of functions now always returns quoted CQL terms.
320 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
322 --- 4.2.23 2011/12/15
324 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
325 sequence is treated as one. For example, &&a=b&&&c& is identical to
328 --- 4.2.22 2011/12/05
330 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
331 APDUs for a connection to a WRBUF.
333 --- 4.2.21 2011/11/23
335 Fix cql_sortby_to_sortkeys. Completely broken before.
337 Make CCL's @truncation work again.
339 --- 4.2.20 2011/11/09
341 New ZOOM connection setting: tproxy. It's like proxy, but does not
342 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
343 to set resolved address + port for a connection outside ZOOM itself.
345 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
347 --- 4.2.19 2011/11/07
349 Fix uninitialized variable in Solr spell support (could cause SEGV
350 for SRU response decoding).
352 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
353 back-end's addinfo through into the ZOOM response addinfo.
355 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
356 they are separated by a colon and a space rather than simply
359 --- 4.2.18 2011/10/28
361 Add support for Solr spell-checking/suggestions through ZOOM.
362 If a Solr target has been configured correctly for spelling-checking
363 and suggestions, these will now be returned on the ResultSet option
364 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
366 --- 4.2.17 2011/09/28
368 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
369 with a flag whether to substitute escape sequences or not.
371 --- 4.2.16 2011/09/22
373 Fix nmem_strsplit_escape to substitute escape char properly.
375 New option for zoomsh -e , which makes it abort on first error and
376 return process exit code to indicate success/failure.
378 YAZ options utility supports special option -- which makes all it treat
379 all following arguments as non-options.
381 --- 4.2.15 2011/09/16
383 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
384 searched if absolute filename is given.
386 Fix conv_xslt() error-reporting when stylesheet is not found.
387 (The value of fullpath is meaningless in this situation.)
389 --- 4.2.14 2011/09/07
391 Fix problem in CQL sort node creation: un-initialized memory.
393 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
394 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
395 CQL sortby depending on whether Type-1 or CQL is actually sent to the
398 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
399 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
401 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
402 will make it possible to use both single-character mask (#) and wildcard (?)
403 in CCL . Throw diagnostic for left truncation because that is not supported
406 --- 4.2.13 2011/09/01
408 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
409 cases using escapes (\-sequences) and masking.
411 PQF parse fix: A trailing backslash followed by end-of-string (\0)
412 would result in a read one byte beyond string.
414 rpn2ccl may use Z39.50 masking for terms (t=z).
416 ICU check fix. Don't include library -lCrun on Solaris, unless present.
418 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
419 not --cppflags (which seeems like an error in icu-config).
421 --- 4.2.12 2011/08/27 RPM package only
423 cql2ccl: fix conversion of terms: operator characters were not
426 --- 4.2.11 2011/08/25 RPM package only
428 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
429 CCL parser will map both # and ? to their regular expression
430 quivalents (. and .*).
432 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
433 of reserved CQL characters.
435 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
436 is, so that they are passed through.
438 --- 4.2.10 2011/08/24
440 ZOOM SRU mode: more aggressive re-connect.
442 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
443 made available as a utility function, declared in <yaz/logrpn.h>
445 rpn2cql_structure() supports proximity nodes (except that the Type-1
446 proximity node's "exclusion" binary is ignored, as there is no way to
447 express that in CQL). Fixes bug #4564.
451 Fix SEGV that could occur if set command of zoomsh was given without
452 value (2nd argument).
454 Fix SEGV that could occur if unsupported transport was given for
455 COMSTACK - say https (when SSL was unavailable).
457 Build yaz-url on Windows too.
461 New utility to get web content. Header is url.h. A command line tool
462 yaz-url is part of the distribution and packages.
464 Fixes for SSL COMSTACK (when gnutls is in use).
466 New functions yaz_base64{encode,decode}. Header is base64.h.
470 ZOOM C includes HTTP response buffer as additional info if it fails
471 to decode the SRU response.
473 Make wrbuf_json_puts available.
477 zoom: throw diagnostic for invalid value for option "sru". Before a
478 bad SRU request was sent.
480 Adding new utility wrbuf_vp_puts.
482 Add cclxmlconfig.obj to win/makefile. It was missing completely.
486 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
487 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
488 redirect was used at the same time.
490 MARC line mode decoding: be less picky about length given - first
491 5 digits of header that is.
493 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
495 Changes to decoding of SRU records: a record with recordPacking=xml is
496 modified with a new root element <yaz_record> if the recordData contains
497 multiple children elements. This is to make the record XML parseable
500 RPN to SOLR conversion: encode special characters.
502 Generic Frontend Server: fix uinitialized member, stepSize.
506 Fix a bug in SRU decoding of records.. The database records stored
507 had un-initialized memory, but it would only be seen with yaz_record_render
508 and type_spec="ext" .
510 Fix a bug in ccl_qual_dup introduced in 4.2.3.
514 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
518 Add new utilities to convert from CQL to CCL . These utilities have
519 prefix cql_to_ccl defined in cql.h.
521 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
522 lead to memory heap corruptions when ICU utilities were in use.
526 Make compilation work without Libxml2.
528 yaz-client: remove redundant blanks in display of searchResult-1 term
533 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
534 resulting CQL node (tree) in a new node CQL_NODE_SORT.
536 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
537 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
538 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
539 Note that the CQL sortby spec is only converted when the GFS is already
540 converting from CQL to RPN (cql2rpn element).
542 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
543 specify whether to collapse delimitors or not. The existing nmem_strsplit
544 do collapse (collapse parameter = 1).
546 Windows installer: For NSIS, set InstallDir depending on x86/x64.
548 Rename internal func yaz_use_attribute_create. While non-static, this
549 function is not declared in a public header.
553 Add -lCrun when linking with ICU on Solaris.
555 More quicks character set conversions for OPAC records.
559 fix problem with record_render: records were converted (character set
560 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
564 SRU: add methods for handling DADS SRU-proxy facets.
566 Separate OPAC record character set for ZOOM_record. yaz_record_render
567 allows a character set given as charset=from/opacfrom,to where 'from' is
568 the character set of a bibliographic record, 'opacfrom' is character set
569 of OPAC record and 'to' is the target character set.
573 yaz-client: show may XML format records. Command show followed by 'format'
574 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
577 src/stemmer.c: Avoid using unnamed union. It is not supported by some
580 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
583 Update yaz.spec to operate on both SLES11 / Centos 5.5.
585 RPM: Release includes 'indexdata' name. Use indexdata in release name so
586 this package can be distinguished from other vendors.
588 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
589 as determined by configure
591 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
593 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
594 returns no error and no record, the present request is considered
595 partial (only a subset of the records could be returned by backend), and
596 so it is appropriate to set Present Status to partial-4.
600 Move yaz-config man pages to section 1.
602 More documentation about SOLR.
604 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
605 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
606 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
607 peers on some Linux systems. However, in general that does not work
608 so YAZ can not rely on that to work. Debian changed behavior in this
609 respect from Debian lenny to Debian squeeze (still testing as of Oct
611 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
613 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
617 Fix yaz-config output: echo_source not set correctly by configure.
621 SOLR WebService support for yaz-client and ZOOM.
623 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
625 --- 4.0.12 2010/08/17
627 Z39.50 facet support. Facet specifications are passed for search in
628 other-information with ASN.1 as defined in facet.asn and OID
629 .10.1000.81.5 . Facets are expressed as an Attribute list as known
630 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
631 3 is limit (number of entries to get in response). yaz-ztest returns
632 dummy facets if a client asks for them.
634 --- 4.0.11 2010/07/09
636 CCL fixes: bug 2895 and bug 3539.
638 GR1-display: add comma in display - was removed by mistake in
641 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
643 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
645 --- 4.0.10 2010/06/18
647 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
648 result set from a connection. The result set will be on its own
649 thereafter; no operations on it will perform retrievals from a target.
650 Only cached copies are returned.
652 ZOOM C:fix case for HTTP servers responding with Connection:close.
653 Ensure that if there is a current task it is resumed (like fetching
654 more records in a result set) . Bug #3484.
656 PQF parser: use odr_atoi for Odr_int (not atoi)
658 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
659 values that contain any non-digits are treated as string attributes
660 (previously decoding only checked for leading character ([0-9]). PQF
661 encoding: attribute string values are not surrounded by double-quotes.
665 New utility for managing threads - thread_create.h.
667 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
668 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
669 but YAZ' implementation do.
671 Fixes for yaz_cond-functions on Windows 7.
673 DLL export more symbols.
675 zoomsh: show record do NOT render opac.
677 Remove *.la files from Debian and RPM packages.
681 Debian package libyaz-dev depends on libgnutls-dev again (was
682 removed in YAZ 4.0.6, but due to Libtool it is still needed
683 even though yaz-config do not list libgnutls libs).
685 ZOOM: Use only one WRBUF for returning string results for
686 ZOOM_resultset. Reduces memory usage for ZOOM in general.
688 ZOOM: ZOOM_connection do not use a shared pointer to
689 ZOOM_resultset after ZOOM_resultset is destructed by
690 user. Reverts to YAZ 4.0.4 behavior.
694 record-conv: fix problem with at least one XSL conversion -
695 due to probably incorrect usage of XML XSL documents.
699 Fix yaz-config for static mode and the use of SSL (gnutls).
703 Forward decl timeval struct in mutex.h and gettimeofday.h.
705 yaz-config: fix 'static' mode linking.
709 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
710 are wrappers for pthreads or Windows. For Windows these are put in
711 a separate DLL: yaz_cond4.
713 libyaz.la (whole source) is compiled with thread. If thread support
714 is enabled enabled, all source of YAZ is compiled with treading support.
715 This allows core utilities such as yaz_log to use thread facilities.
716 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
717 thread utilities. This commit moves mutex utilities (mutex.c) from
718 libyaz_server.la to libyaz.la.
720 yaz-json-parse displays leading text until error.
724 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
725 patch from Giannis Kosmas.
727 SRU: no longer URL encode SRU database. The URL for an SRU server is
728 a URL and such is alreeady encoded - at least when given with leading
729 http:// or https://. This reverts behavior to YAZ 3.0.50.
731 Support for new MARC XML notation TurboMARC which like MARCXML is a
732 complete representation of MARC/ISO2709.. This one, however, is more
733 compact and allows for faster processing with XSLT. TurboMARC can be
734 used in the marcdisp.h API, from the yaz-marcdump utility and from
737 yaz-ztest can be configured - via the database - to perform certain
738 delays when it performs operations search, present and single record
739 fetch. This allows testers to make yaz-ztest act as a real or even slow
740 Z39.50 server. Refer to the yaz-ztest man pages for details.
744 wrbuf_destroy allows NULL WRBUF passed to it.
746 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
748 Add ZOOM_connection_close.
750 No fixed size buffers for ZOOM shell - bug #3257.
752 tstodr: make it work on s390 platform.
754 New icu iterator-functions. The new icu_iter-functions makes it possible
755 to use ICU chains from many threads.
757 yaz-client: better syntax check for show command.
761 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
764 New simple local-file XML include facility which allows file glob-patterns.
765 Refer to yaz/xml_include.h.
767 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
770 ZOOM_record_get supports new parameter "format" which makes it format XML
773 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
774 JSONText in ECMA-262) is JSONValue, not JSONObject.
778 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
779 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
781 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
782 POSIX/Unix builds .so with major version 4.
784 Remove old LOG_-defines from log.h. They have been obsolete and
785 undefined by default for the last 5 years.
787 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
789 GFS: Remove socket (int *fd) from search_rr handler. The socket
790 descriptor ptr is a facility that allowed a search handler to supply
791 a socket which would serve as a callback - when search was complete.
792 This facility has now been in use for years.
794 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
795 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
796 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
797 returns 'const char *' rather than 'char *. The returned string is
798 read-only and should not be modified by applications. COMSTACK cs_close is
799 now a void function - it no longer returns int. No applications check for
800 the value and the implementations has always returned 0.
802 ZOOM: use size_t for scan hit counts and str size. Functions
803 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
804 occ (hit count) and len (string length) are now of type size_t pointer
805 rather than int pointer. This is to be able to represent large hit counts
806 and to also just to use the proper type for string length (strlen result).
808 New JSON parser. Refer to include/yaz/json.h .
810 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
811 Used to be int in some cases. Many wrbuf_-functions used to return an int
812 indicating some length.. These return values were never used. And so they
815 ODR: odr_malloc, odr_total now takes size_t for size.
817 clone_z_type: fix leak; occurred for encoding failures.
819 --- 3.0.52 2009/12/03
821 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
822 bug was introduced in 3.0.51.
824 --- 3.0.51 2009/12/02
826 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
828 tcpip comstack: fix leak for getaddrinfo.
830 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
831 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
832 Decoding of SRU "path" database is performed by private function
833 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
834 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
836 yaz-client: honor base command for SRU. Change when database setting
837 is applied for SRU and ensure it is kept when a connection is reset.
838 Change also the way errors are displayed or SRU (decoding of packages).
840 --- 3.0.50 2009/11/02
842 Add support for extra request / response data for SRU codecs and GFS.
843 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
844 for extra data response buffer and length. For the GFS, both request
845 and response data (XML) is carried in extra_args and extra_response_data
846 for the search handler. Patch by Ko van der Sloot.
848 ZOOM: For queries that cannot be converted to the specified rpnCharset,
849 ZOOM now returns a diagnostic on the client-side ('invalid query' /
850 10010). This fixes bug #2113.
852 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
853 cmdfile included a 'quit' command that would result in a memory violation.
855 --- 3.0.49 2009/10/01
857 Make a number of functions defined in xmlquery.c static. These have
858 never been declared in a public header file (yaz/xmlquery.h) and was
859 made public by mistake.
861 Improve speed of character conversions (iconv utilities). This makes
862 conversions from MARC-8 faster.
864 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
865 unless type desired is "raw". This will prevent type "xml" from
866 returning ISO2709 .. Which obviously can not be XML parsed.
868 Fix memory leak in ZOOM that would occur if option apdulog was used
869 on a re-used connection.
871 Frontend server logs HTTP requests.
873 Frontend server now sends Z39.50 close when it times out (sesssion has
874 been idle for too long). Versions 2.0.30 and earlier also sent close.
875 But due to a mistake this was disabled in all versions after that, i.e.
876 the server would just close the socket immediately.
878 yaz-client emits a better message when receiving an unrecognised
879 userInformationField.
881 Skip zero-length subfields when decoding ISO2709. This rare case happens
882 if a record has two FS characters in a sequence. Without this patch
883 there would be a reference beyond char array in using_code_len fragments
886 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
888 --- 3.0.48 2009/08/28
890 The show command offered by the zoomsh command now takes a 3d optional
891 parameter type which is what is passed to ZOOM_record. If the type
892 argument is omitted, "render" is used.
894 RPN to CQL conv may use USE string attributes (bug #2978).
896 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
898 --- 3.0.47 2009/07/08
900 Function yaz_xml2query allows a diagnostic element in the PQF XML
901 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
902 code and additional info respectively.
904 The BER BOOLEAN is now the integral type Odr_bool which still happens
905 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
906 typedef'd to Odr_int. This is still an integral 'int', but it may be
907 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
908 ASN-1 compiler as well as programs has been updated to use the new types.
910 --- 3.0.46 2009/06/08
912 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
913 only the bibliographic record was rendered. For type=opac, an OPAC
914 record is only returned if it is present.
916 iconv: small fix for encoding of advancegreek.
918 yaz-client: avoid double display of SRU/SRW records (bug #2798).
920 yaz-client: option auto_reconnect=on really reconnects.
922 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
924 server: avoid null ptr ref for for yaz_poll errors.
926 build: fix RPM build for RHEL 5.3.
928 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
930 --- 3.0.45 2009/03/31
932 Fixed bug #2709: TCP connect returns Invalid argument.
934 Fixed compilation for mingw.
936 Honor charset for raw records (ZOOM_record_get).
938 Fixed use of errno for threaded mode that was seen on Solaris 10.
940 Fixed argument passing with blanks in value for Windows Service.
942 Disable YAZ' own log rotate by default (no 1 GB limit).
943 The variable l_max_size which specifies the log file limit is set to 0
944 (DISABLED): This is due to the fact that YAZ is most often deployed using
945 logrotate. Also YAZ can not perform log rotate because of unsufficient
946 permissions (setuid).
948 --- 3.0.44 2009/02/17
950 List supported encodings in man page for yaz-iconv.
952 Fixed missing SSL libs for --libs output
954 Re-established OID record syntax application-xml. Nobody should use it
955 but we don't want to change soname because of this symbol being absent.
957 --- 3.0.42 2009/02/02
959 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
961 Added member named_result_sets for init handler struct for the GFS. This
962 allows a server to disable named result sets.
964 Removed OID record syntax application-xml.
966 Added support for rule-based transliterator for ICU wrapper of YAZ.
968 Fixed bug #1902: yaz-icu XML output.
970 Make YAZ checks Emacs friendly.
972 BITSTRING value shows value. Bug #2346.
974 ISO2709 decoding: skip control characters from indicator data.
976 Omit sort key by default in yaz-icu's output.
978 Allow combined single char options (again) for YAZ' options function.
980 Utility yaz-marcdump got option to display YAZ version (-V).
982 Allow YAZ to use ICU 3.4.
984 Added new ICU test case which illustrates removal of diacritics.
986 --- 3.0.41 2008/12/29
988 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
990 --- 3.0.40 2008/12/29
992 For configure, using option --without-xml2 also disables Libxslt/Libexslt
995 Fixed bug #2352: yaz-marcdump crashes for certain record.
997 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
999 Added support for Danmarc2 to UTF-8 conversion.
1001 Added support for ISO5426 to UTF-8 conversion.
1003 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1004 implementation version.
1006 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1008 --- 3.0.38 2008/11/10
1010 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1011 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1013 ZOOM C now interprets databaseName option for ZOOM connection as path
1016 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1018 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1020 Dummy Libxml2 types no longer defined in headers of YAZ'.
1022 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1025 --- 3.0.36 2008/09/26
1027 Various ODR chapter fixes.
1029 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1031 Added missing source for Windows compilation, mutex.c.
1033 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1035 For SRU connections in ZOOM all records up to "count" are now fetched.
1037 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1038 in Windows due to bad error handling for Libxml2.
1040 Added facility for sending arbitrary records (ASN.1 any) using
1041 ZOOM C's Extended service update. Patch by Sam Reynolds.
1043 New options for ZOOM C's connection, logapdu which makes ZOOM log
1046 --- 3.0.34 2008/06/18
1048 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1050 --- 3.0.32 2008/06/12
1052 Fixed memory violation that could occur when decoding UTF-8. This bug
1053 was only present in 3.0.30 of YAZ.
1055 --- 3.0.30 2008/06/06
1057 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1058 GNU TLS is used by default (if found).
1060 yaz-ztest returns OPAC records if a client asks for OPAC.
1062 Improved speed of MARC-8 encoding.
1064 Added support for lossy and loss-less MARC-8 encoding.
1066 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1068 Added new Windows Service wrapper (sc).
1070 yaz-client's itemorder command may now send a file.
1072 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1074 Added new function yaz_log_xml_errors.
1076 Allow (but warn) unknown XML attributes in MARCXML parsing.
1078 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1080 The UTF-8 to MARC-8 conversion now uses a different set of characters
1081 for Greek symbols. Bug #2120.
1083 --- 3.0.26 2008/02/21
1085 Added yaz_daemon (daemon.h).
1087 Fixed bug #2068: pkg-config trouble
1089 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1091 --- 3.0.24 2008/01/28
1093 Document --with-xml2 option.
1095 Added OPAC XML XSD (etc/opacxml.xsd).
1097 Allow glob mask for name attribute in retrieval element for the
1098 generic frontend server's retrieval facility.
1100 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1101 except POLLIN/POLLOUT.
1103 Fixed error handling in cs_listen. Bug #2037.
1105 --- 3.0.22 2008/01/20
1107 Fixed version in yaz/yaz-version.h.
1109 Fixed bug #2027: Crash when closing connection.
1111 Changed configure so that ICU support is only enabled if only ICU
1112 and Libxml2 is available (because the ICU chain is XML based).
1114 --- 3.0.20 2008/01/15
1116 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1117 is built. Only this DLL depends on the ICU runtime.
1119 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1120 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1122 Changed license of CCL module to 'Revised BSD'. After consultation with
1123 remaining members of the original EUROPAGATE consortium, we are re-issuing
1124 the CCL module without a separate license. The software was developed by
1125 Index Data as part of a research project. The special license was included
1126 to help feed usage information back to the project consortium to support
1127 project evaluation. At this time, the project consortium has long-since
1128 disbanded, and the majority of the original principals have retired. At the
1129 same time, we have significantly modified the software during the following
1130 years, to the point where very practically no original code remains. To
1131 simplify re-use of the software, we have contacted those members of the
1132 consortium who could be reached, and agreed to re-issue the module as a
1133 proper part of the YAZ package.
1135 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1137 CQL closer to being version 1.2 compliant. CQL also allows free-form
1138 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1141 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1142 bug could make Extended services handling crash in the ZOOM layer. This
1143 bug was only present in YAZ 3.0.18.
1145 --- 3.0.18 2007/12/19
1147 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1150 yaz-marcdump reads and writes collection wrapped records.
1152 Handle OPAC for record conversion module.
1154 Fixes for ICU wrapper.
1156 Allow ICU libs to be controlled with --with-icu .
1158 --- 3.0.16 2007/11/12
1160 Added yaz_poll which is a wrapper for select/poll. When poll is available
1161 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1162 sockets to be in use.
1164 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1165 functionality through an XML based configuration (ICU chain). This system
1166 is useful for search facilities such as Pazpar2 and Zebra that needs to
1167 perform tokenization of indexed material. The ICU code in a separate
1168 library libyaz3_icu.a.
1170 Added HTTP tunnel facility for COMSTACK, bug #1752.
1171 This is a facility that allows a Web proxy, such as squid, to tunnel
1172 Z39.50 traffic. This facility is "transparent" to must applications
1173 using YAZ. It's enabled by using pseudo transport connect: followed by
1174 the proxy address, followed by command, then follwed by he regular
1175 "virtual" addresss. For example,
1176 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1178 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1180 --- 3.0.14 2007/09/21
1182 Fixed bad memory reference in ZOOM_record - cuased by member not being
1183 initialized. This was a problem only in YAZ 3.0.12.
1185 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1186 fields were not removed.
1188 Changed the way C code is generated from codetables.xml. Made a MARC-8
1189 conversion trie for each characterSet section rather than codeTable.
1190 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1191 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1193 --- 3.0.12 2007/09/12
1195 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1196 from ZOOM_record_error).
1198 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1200 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1202 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1204 Better SRW-to-Bib-1 diagnostic mapping.
1206 ZOOM C and yaz-client announces SRU version 1.2 by default.
1208 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1211 Fixed in yaz_sru_decode to allow other version than 1.1.
1213 --- 3.0.10 2007/08/22
1215 Added support for SRU scan for ZOOM.
1217 Added support for the use of the older versions or Extended Service
1218 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1219 set to the version , 1=first, 2=second, 3=third. The third version is
1220 what ZOOM C has used so far. And that, obviously, is the default.
1222 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1223 therefore in Zebra and in SimpleServer-based applications). The new
1224 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1225 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1226 which is passed into the back-end search callback function.
1228 Added support for HTTP Basic authentication in clients: the SRU/W
1229 codec encodes the username/password elements of the PDU structure
1230 appropriately, and these may be set using the "user" and "password"
1231 options in ZOOM-C applications (the same options that are used for
1232 Z39.50 authentication).
1234 --- 3.0.8 2007/06/25
1236 Fixed bug #1208: SSL appears to be broken in ZOOM.
1238 Fixed bug #1206: Libxml2 include path weirdness.
1240 Added oid_name_to_dotstring.
1242 Allow elementSetName to be specified for ZOOM C record update.
1244 Allow waitAction to be specified for ZOOM C based for Extended Services.
1246 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1247 syntax OID. Bug introduced in YAZ 3 series.
1249 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1251 --- 3.0.6 2007/06/06
1253 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1254 directory. yaz-client now reads commands from file given by option -f
1255 if specified; then tries to read .yazclientrc in current directory.
1256 Failing that, it reads .yazclientrc from user's home directory.
1258 Added support for correlationInfo Note and ID for Record Update via
1261 Added yaz-client command querycharset which specifies character set for
1262 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1263 (termListAndStartPoint).
1265 Charset ISO5428:1984 is an alias for ISO5428-1984.
1267 Implemented a way to perform scan in a result set using Z39.50. This
1268 is achieved by attaching the result set name in the characterInfo
1269 (type InternationalString) of OtherInformation in the Scan Request PDU.
1270 The result set is identified in the otherinformation by the new OID:
1271 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1272 This allows for scan in result set and faceted search . Zebra did some
1273 of this in the APT term using attribute type 8 and value being result
1274 set. Using the OtherInformation approach for this is cleaner and easier
1275 to work with in proxies and the like. This facility can be used in
1276 yaz-client using new command setscan which takes a result set as first
1277 argument, start position (APT) as second.
1279 Changed decoding of SRU XML packed records to deal with servers that
1280 have recordData with XML data with multiple root nodes. Also make
1281 comparison for recordPacking case insensitive. Again, one server
1282 returns "XML" where others return "xml".
1284 For SRU responses allow Content-Type application/xml as well as text/xml.
1286 --- 3.0.4 2007/05/21
1288 Fixed bug in character set conversion of BER strings. Bug introduced
1291 --- 3.0.2 2007/05/08
1293 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1295 For OID class, use oid_class consistently.
1297 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1300 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1301 character set for bibliographic information interchange". By Giannis Kosmas.
1303 Added documentation on new OID API.
1305 --- 3.0.0 2007/05/02
1307 Changes to generic frontend server interface: added new member
1308 'query_charset' for bend_initrequest structure. A backend init handler
1309 should set this member to its native character set for query terms.
1310 When defined, the frontend server logic will announce this character set
1311 to a client if the negotiationModel bit is set by the client. All server
1312 implementors are encouraged to specify this. If a backend server does not
1313 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1315 Added CCL utility to remove terms (stop words) from resulting RPN
1316 tree. This is handled by functions with prefix ccl_stop_words_ .
1318 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1319 terms in RPN queries.
1321 Clean-up the CCL API. Moved some internal structures from ccl.h to
1322 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1323 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1324 This is replaced by ccl_parser_find_str which takes a string instead.
1326 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1327 libyaz.la is the core of YAZ except the generic frontend server and
1328 does not depend on POSIX threads anymore. libyaz_server.la is the
1329 generic frontend server facilities and uses POSIX thread functionality
1330 if available. The libyaz.la no longer depends on POSIX threads because
1331 the number of global structures is limited. NMEM no longer re-uses blocks
1332 between threads ; it simply free's memory immediately but allocates in
1333 "large" chunks as usual. We don't expect any performance penalties
1334 because of this. The yaz_log system is still using a global log_level so
1335 caution must be taken when modifying it with yaz_log_init_.. +
1336 yaz_log_mask_str. This, however, should not cause any trouble because
1337 these functions are called during initialization of application code
1338 anyway. `yaz-config --libs server` returns libs for server applications;
1339 `yaz-config --libs` returns libs for non-server applications.
1341 New OID database - with public definitions in oid_db.h. Removed old OID
1342 database including the head oid.h and definitions such as enum oid_value
1343 and struct oident. The new OID database uses the same string names as
1344 before but the 'protocol' is gone. There are now only two representations
1345 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1346 converts from string to OID; functions with prefix yaz_oid_to_string
1347 converts the other way.
1349 Change to emit_term() in CQL-to-PQF query translation: when a term has
1350 the /regexp relation modifier, do not process it for leading and
1351 trailing "^" and "*", which have quite different meanings in regular
1354 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1355 write handlers no longer carries a 'last' parameter. This will make
1356 yaz_iconv flush "less" characters. A flush is performed by call to
1357 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1359 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1360 removed, because function yaz_query_to_wrbuf does the same.
1362 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1363 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1365 Deprecated MARC utility functions removed.
1367 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1370 Branch split: YAZ_2_1_55_branch
1372 --- 2.1.54 2007/03/16
1374 Fix to ZOOM-C so that transparent reconnection is properly handled on
1375 connections that are in asynchronous mode.
1377 Fixed compilation on OpenBSD 4.0.
1379 Large strings in GRS-1 records are now properly displayed in yaz-client.
1381 Added character conversion support for "advancegreek"; based on patch from
1384 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1385 sequence is met. Before the error was not set so it would be unknown.
1387 Adjust yaz-marcdump MARC reader so that it skips until record separator
1390 --- 2.1.52 2007/03/07
1392 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1393 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1394 fd_set structure used as a bitmask for the FDs to be selected on.
1396 Using ACX_PTHREAD macro to check for POSIX threads.
1398 Fixed have-vsnprintf check.
1400 --- 2.1.50 2007/02/23
1402 Fixes for configure on BSD. Bug #900.
1404 Added snprintf/vsnprintf wrappers for systems that don't have
1405 limits (heavens forbid).
1407 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1408 created before all previous tasks were completed and removed from the
1409 task queue, the new task could be removed by a mistake.
1411 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1413 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1415 Fixed bug #832: Problem with MARC/charset in yaz-client.
1417 Fixed bug #668: save command line history for yaz-client.
1419 Fixed bug #830: pkg-config support.
1421 --- 2.1.48 2007/01/23
1423 Extended ZOOM result set options with two options that may be read by
1424 a client: resultSetStatus and presentStatus with values as specified for
1426 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1428 Fixed bug #827: Using SSL fails on Debian etch.
1430 Fixed bug #826: Weird looking chars for set of MARC records.
1432 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1433 that is treated as an ItemOrder with itemRequest being an XML document
1434 external. The value of "doc" is the content.
1436 Extended the GFS search facility. New member of bend_search_rr
1437 'estimated_hit_count' signals that hits is known to be an estmate
1438 (higher or lower than real hit count). New member 'partial_resultset'
1439 signals that the search was partial (hit count is lower or equal than
1440 real hit count). For Z39.50, the information is stored in resultSetStatus
1441 member of SearchResponse APDU. For SRU, the information is signalled
1442 via SRU diagnostic 59: "Result set created with valid partial results
1445 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1447 --- 2.1.46 2007/01/13
1449 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1451 Added ZOOM_connection_peek_event.
1453 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1454 the following new functions:
1455 ZOOM_event_nonblock, ZOOM_connection_process,
1456 ZOOM_connection_get_{socket,mask,timeout},
1457 ZOOM_connection_fire_event_{timeout,socket}.
1458 The existing blocking event handler, ZOOM_event, is a wrapper for the
1459 + blocking ZOOM_event_sys_{poll,select}.
1461 Implemented function ccl_xml_config which parses XML version of CCL
1462 configuration (bug #798).
1464 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1466 Added timings utility (yaz/timing.h)
1468 --- 2.1.44 2007/01/03
1470 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1473 Fixed bug #779: Rotation of apdu.log fails.
1475 Fixed for character set conversions:
1476 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1477 Honor G1 set in MARC-8 decoding.
1479 --- 2.1.42 2006/12/17
1481 Fixed bug #775: char conversion does not handle Alternative UTF-8
1484 Implemented function yaz_marc_read_line which parses MARC line format
1485 records. There is a wealth of formats out there. So far, this function
1486 reads line records produced by yaz_marc_write_line.
1488 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1489 more generic and easier to remember(!) options: -i format and -o format
1490 which specifies input format and output format respectively - where
1491 format is one of "marc", "marcxml", "line", "marcxchange".
1493 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1494 does not print anything except warnings for records.
1496 For yaz-marcdump, added support for MARC split into files (-s) with a given
1499 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1500 spec, at http://www.loc.gov/standards/sru/record-update/
1501 This has changed the binary layout of the following structs:
1502 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1503 bend_update_rr . Patch by Ko van der Sloot.
1505 Added GFS utility function bend_assoc_is_alive which returns 1 if
1506 association is still alive (client is connected); 0 otherwise (client
1507 closed connection). This allows busy servers to stop working for
1510 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1511 been a separate piece of software. This version of ziffy has been modified
1512 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1514 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1516 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1517 Client code may now interrogate options such as "init_opt_sort" to
1518 find out whether the server claims to support various options.
1520 --- 2.1.40 2006/11/27
1522 Added utilities yaz_{set,get}_esn to set/get element set name from
1525 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1526 of YAZ and has been so since YAZ 2.1.10.
1528 Implemented ZOOM_record_error which returns error information for
1529 record (surrogate diagnostic).
1531 --- 2.1.38 2006/10/31
1533 Updates for SRU Update by Ko van der Sloot:
1534 1. Changed name from "operation" to "action"
1535 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1536 versions in the code, marked as 'backward compatible'.
1537 3. Added diagnostics for SRU Update.
1539 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1541 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1543 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1545 For GFS, fixed problem with SRU diagnostic 'First record position out of
1546 range' being issued for 0 hits.
1548 zoomtst10 part of Windows Build.
1550 --- 2.1.36 2006/10/13
1552 Implemented yaz_filepath_comp which splits a path into file path
1553 components (required by Zebra 2.0.3+).
1555 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1556 BSD inspired license until now so this should not have any real impact on
1557 anybody. See http://www.opensource.org/licenses/bsd-license.php
1559 Fixed bug #687: Missing log lines.
1561 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1564 Fixed bug #689: SRU diagnostics to be added.
1566 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1567 whether a connection is idle (no more work do do).
1569 --- 2.1.34 2006/10/04
1571 Change type of optval from long to int for invocation of setsockopt with
1572 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1574 Added support for specifying the max log file size for the Generic
1575 Frontend Server. The size is given with option -r.
1577 --- 2.1.32 2006/09/21
1579 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1581 --- 2.1.30 2006/09/17
1583 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1586 Fixed bug in Generic Frontend Server that could cause a server to stop
1587 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1589 For the generic frontend server, the maximum record size is used as maximum
1590 size of incoming packages (SRU + Z39.50). The value until was previously
1591 only used in Z39.50 Init negotiation and, later, in a session controlled
1592 sizes of records returned. This is controlled using -k option. It can be
1593 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1595 --- 2.1.28 2006/09/04
1597 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1600 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1602 New option for yaz-marcdump -lpos=value which allows setting a portion
1603 of MARC header to a certain value.
1605 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1607 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1608 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1610 --- 2.1.26 2006/08/15
1612 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1615 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1617 --- 2.1.24 2006/08/08
1619 Fixed MARC ISO2709 encoding routines to deal with character set
1622 Minor changes to GFS logging. Database included in search request log
1625 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1626 cached/multiple records.
1628 Shared libraries are built by default on Unix+configure.
1630 Changed cql2pqf transformation to use a different evaluation order. The
1631 new order is: always, relation, structure, position, truncation, index
1632 and relationModifier. Old order was: always, relation, relationModifier,
1633 structure, index, position, truncation. Note that the the latter ones
1634 override former ones for identical attributes.. The new scheme means that
1635 it is possible to override any existing attribute with a relationModifier.
1636 And also that it is possible to override everything for the index rule
1637 (except the ones listed in relationModifier). No order is perfect but this
1638 one, we believe, covers more real cases.. The "always" should have been
1639 called "default", since the attributes there can be overridden with all
1642 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1643 compilation phase, but also for yaz-config --cflags output. This allows
1644 us to have public headers with Libxml2 stuff in them . It should also,
1645 eventually, make Libxml2 checks redundant in packages using YAZ, such
1648 --- 2.1.22 2006/06/15
1650 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1651 stored in uri, message and details.. Previously diagnostics were stored
1652 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1653 compatibility.. but he's probably the only one affected, so.
1655 Added support for CCL, compiled on the client side, in ZOOM-C. This
1656 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1657 input; the resulting query objects can be used for for searching with
1658 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1660 YAZ' configure searches for OpenSSL by default.
1662 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1663 SL_CTX_use_certificate_file. See
1664 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1665 for more info. Thanks to Ko van der Sloot.
1667 --- 2.1.20 2006/06/02
1669 Bug #600: SRU GET, POST support for yaz-client. Introduced
1670 command 'sru' which selects method SOAP/GET/POST.
1672 Allow missingValueAction to be specified for the sortspec string -
1673 function yaz_sort_spec. By default, the missing value action is null.
1674 Use ! to specify "abort". Use = followed by stringvalue to specify default
1677 Ensured that Present-handler (if defined) is called in GFS before any call to
1678 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1679 searchRetrieve requests.
1681 Documentation for YAZ is now based on the Docbook XML/XSLT using
1682 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1683 is no longer depending on jade/openjade or docbook-to-man scripts.
1684 PDF is no longer part of the distribution - but can optionally be
1685 made using DSSSL/jadetex or FOP.
1687 Added retrieval handling support in Generic Frontend Server to support
1688 conversion between MARC/XML as well as XSLTtransforms. See
1689 etc/yazgfs.xml for an example.
1691 Added Authentication support to Generic Frontend Server in SRU
1692 mode. Authentication using HTTP Basic is supported, as is the use
1693 of 'x-username' and 'x-password' parameters in the request itself.
1695 Added support for a new character set MARC8s identical to MARC8 except
1696 that it converts combined characters to single Unicode characters in the
1697 Latin-1 range (when possible).
1699 --- 2.1.18 2006/04/24
1701 ASN.1 compiler 0.4: generates brief Doxygen file header for
1702 generated .h/.c files.
1704 Utility yaz_iconv now supports conversion to MARC-8.
1706 New facilities for the MARC module. The reading - and writing of
1707 content are separate methods for the yaz_marc_t handle. The following
1708 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1709 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1710 format). Write functions have prefix yaz_marc_write_.. The existing
1711 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1712 available. Removed support for OAI-MARC and simplexml (not the
1713 simplexml from PHP5).
1715 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1716 to be returned for this connection.
1718 --- 2.1.16 2006/03/31
1720 Allow multiple languages and charsets to be specified with
1721 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1722 negcharset iso-8859-1,utf-8
1724 Translation of proximity nodes from CQL into PQF now works.
1726 Moved to automake 1.8, 1.9.
1728 Added function yaz_log_set_handler which allows a log handler to be
1729 installed. This handler will be called for all log messages. Output
1730 to file is also produced; but that can be disabled by passing NULL
1731 fname to yaz_log_init_file.
1733 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1735 For SRW (including GFS), accept application/soap+xml as content-type
1738 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1739 produces NO stylesheet reference even if a default stylesheet is specified
1742 --- 2.1.14 2006/03/14
1744 Updated Windows package to include yazd.dll + yazd.lib for the
1745 Development component.
1747 If the environment variable YAZ_LOG is set, then it is used as a
1748 string indicating the default level of logging to use if not
1749 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1750 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1751 used as before. So, for example, to omit warnings from YAZ logging,
1752 export YAZ_LOG=-warn
1754 cql_transform() now map structure and other attributes before indexes,
1755 so that index-specific structures and other attributes can override
1756 defaults. So now a combination of mapping specifications such as:
1758 index.dc.date = 1=date-modified 4=5
1759 does the right thing.
1761 cql_transform() now also respects the "always" mapping specification,
1762 which establishes an initial set of attributes to be used for all
1763 terms except where overridden by more specific attributes associated
1764 with the index, relation or modifier.
1766 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1767 which mode to use; one of "post", "get" or "soap" (SRW, default).
1769 Fixes for yaz_iconv routines: changed trie-based character set conversions
1770 to use only non-negative values for bit fields due to Sun's C compiler not
1771 supporting negative values.
1773 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1774 sequences where not read correctly. Fix by Rustam Usmanov.
1776 Updated win/makefile to use options, settings which makes things
1777 compile with VS C 2005.
1779 --- 2.1.12 2006/02/01
1781 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1783 In ZOOM socket code, use select instead of poll on MacOSX.
1785 ZOOM-C now support client-side compilation of CQL into RPN that is
1786 sent to the server, enabling CQL to be used against all Z39.50
1787 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1788 ZOOM_query object, and submit it using ZOOM_connection_search().
1789 The CQL-to-RPN translation uses a configuration file, the name of
1790 which must be specified in the Connection's "cqlfile" option.
1792 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1793 function, which takes as its start-term parameter a ZOOM_query object
1794 (which may have had either CQL or RPN set into it).
1797 --- 2.1.10 2005/11/29
1799 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1800 GFS to support this as well. Backend handler, bend_srw_update, does the
1801 update work. Code contributed by Ko van der Sloot.
1803 Allow retrieval of Search Result-1 information in ZOOM by the use of
1804 options that are attached to a result set. ZOOM documentation updated
1807 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1808 UTF-8 conversion. Patch by Raj Patel.
1810 Added option -m to GFS to control formatting of timestamps in log file.
1812 Added 'exit' as synonym for 'quit' in yaz-client
1814 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1815 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1816 for the new members. Patch by Ko van der Sloot.
1818 Added support for SRU POST. It is supported for content-type
1819 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1821 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1822 Instead make the library libyaz.la multi-threaded. Threading as a whole
1823 can still be disabled by configure option --disable-threads. Previosly,
1824 with older GLIBCs there were problems with MT libs under Apache. This
1825 has now been fixed a long time ago.
1827 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1830 CQL module modified to be case insensitive for relations/indexes/operations.
1832 Fixed bug in CQL transform code: incorrect value relationModifieder
1835 Added 'show all' command for yaz-client which retrieves all results
1838 Added new yaz-client, xmles, which takes a (private) OID and
1839 a document to be sent as an extended service request.
1841 Describe new yaz-client commands wait_response and set_auto_wait.
1843 Increase TCP/IP listener backlog from 3 (which I am guessing was
1844 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1845 that the socket will queue as many incoming connections as it's able
1846 to handle ongoing connections. In other words, it will never now
1847 refuse a connection that it would be able to handle merely because
1848 it's not got around to accepting() enough of the pending connections
1849 yet. This is the behaviour anyway under Linux, where the listen()
1850 argument is ignored; but not under BSD and on systems such as
1851 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1852 YAZ-based servers should now be uniform across operating systems in
1855 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1856 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1857 This allows yaz-marcdump to read large MARC batches (>2 GB).
1859 Modified all YAZ source files - except the source which is auto-generated
1860 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1863 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1864 corresponding to the existing *_setl() function. These allow option
1865 values containing arbitrary valuues.
1867 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1868 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1869 except that it returns an indicator of whether or not the sort
1870 criterion was accepted (0 for OK, -1 for invalid).
1872 --- 2.1.8 2005/06/07
1874 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1875 MARC output rather than returning "new" buffer.
1877 yaz-client warns about unknown init options.
1879 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1881 --- 2.1.6 2005/05/24
1883 Added support for SRW sort in Generic Frontend Server. Patch
1884 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1885 sortKeys - or NULL if none is provided.
1887 Fixed bug #307: It was impossible to specify indefinite/no timeout
1888 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1891 Added support for multiple languages and charsets to be specified in
1892 ZOOM. Each charset/language is separated by a blank. If negotiation is
1893 in effect in init-response, Option
1894 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1895 Code based on patch by Vasiliy Osadchuk.
1897 Fixed bug #306: infinite recursion that occurred when calling
1898 yaz_log_level_init as the first call (before other log level or
1901 Fixed bug in scan handling in front end server: if preferred-Position-In-
1902 Response was non-present, a NULL pointer referece was performed.
1904 --- 2.1.4 2005/04/26
1906 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1907 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1908 now defined for all those error codes. So instead of putting 109 in
1909 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1910 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1912 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1915 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1917 Program yaz-client now exits and produces an error message if multiple
1918 Z39.50 servers are specified on the command line (none or one allowed
1921 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1924 --- 2.1.2 2005/03/16
1926 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1928 Fixed bug #272: Preserve spacing for CCL terms.
1930 --- 2.1.0 2005/03/14
1932 Added support for virtual hosts and multiple backend servers for
1933 the YAZ frontend server. The configution is XML based and
1934 support specificition of CQL to RPN mappings and explain information.
1935 See section "Virtual Hosts" in the YAZ manual.
1937 Extended OPAC display utility. OPAC display utility renders
1938 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1939 to supplement yaz_marc_decode_wrbuf.
1941 Fixed a bug in MARC decoder that could caused it to crash for some
1942 invalid MARC records. More diagnostics and warnings where added in
1943 XML output (warnings, etc are stored in comments).
1945 --- 2.0.34 2005/02/08
1947 Fixes for UNIX domain sockets. Bug #261.
1949 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1951 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1952 Added yaz_marc_subfield_str which defines subfield lead string which is
1953 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1954 yaz_marc_endline_str which defines end of fields string used in
1955 YAZ_MARC_LINE format. Default string is newline.
1957 Experimental support for MarcXChange. This format can be produced
1958 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1959 http://www.bs.dk/standards/MarcXchange.xsd
1961 Added yaz-client commands scansize that sets maximum number of
1962 entries to be returned by scan.
1964 --- 2.0.32 2005/01/11
1966 Added support for SRW scan in yaz-client and Generic Frontend Server.
1968 * Added whereInList member to SRW Scan Term.
1970 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1972 Fixed NMEM system to return aligned blocks on the smallest boundaries
1973 that are suitably aligned for all possible types on the particular
1974 architecture YAZ is being built for.
1976 --- 2.0.30 2005/01/04
1978 Fixed numerious warnings that was issued with newer versions of GCC.
1980 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1981 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1984 Make YAZ Generic Frontend Server slightly faster.
1986 Enhance (and reduce) logging for Generic Frontend Server.
1988 Revert YAZ log system so that it flushes every write operation
1989 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1991 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1992 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1993 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1994 will effectively disable old definitions.
1996 --- 2.0.28 2004/11/09
1998 Added yaz_log_time_format which specifies log format using
2001 Added yaz_log_module_level which returns mask for a module. Value
2002 is non-zero mask a if module is enabled; zero if disabled.
2004 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2005 in include/yaz/cql.h.
2007 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2009 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2011 Fixed bug #172: RPM builds does not enable SSL.
2013 Doxyfile.in part of dist. Doxyfile generated by configure.
2015 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2016 are given and the corresponding component does not exist.
2018 Extend CCL documentation in YAZ reference. Describe r=r.
2020 --- 2.0.26 2004/10/01
2022 Fixed MARC->MARCXML conversion to properly deal with
2023 fields, subfields, indicators having non-ASCII characters.
2025 Fixed MARC->MARCXML conversion so that ASCII control characters
2026 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2029 Added YAZ GFS support for conversion from Z39.50 surrogate
2030 diagnostics to SRW surrogate diagnostics.
2032 Bug fix: YAZ GFS did not return schema in explainResponse.
2034 --- 2.0.25 2004/09/30
2036 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2037 now converts recordSchema to elementSetName as well as schema URI.
2039 Fixed bug in COMSTACK that prevented HTTP request packages from being
2042 --- 2.0.24 2004/09/29
2044 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2045 does not require white-space before and after the dash in a range, e.g.
2046 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2049 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2050 due to new GCC removing "redundant" code.
2052 Added yaz-client commands scanpos and scanstep that sets preferred
2053 position and step-size for scan.
2055 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2057 Added CCL utility ccl_qual_buf which parses one or more CCL
2058 spec lines in a buffer.
2060 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2061 of name and value - ignoring empty lines and comments.
2063 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2065 Added odr_get_element_path which returns current element path for an
2066 ODR handle. This utility is useful in error handling or user-defined
2069 Added ODR_PRINT utility odr_set_stream which is is a more generic
2070 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2071 to a write function and pointer to close function. The close function - if
2072 non-NULL - will be called during odr_destroy.
2074 Fixed bug in CCL parser where truncation char was not removed from
2075 right side when truncation=both was in effect.
2077 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2080 --- 2.0.23 2004/08/11
2082 Fix buffer overrun in CQL parser when dealing with proximity (%).
2084 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2085 to UTF-8/UCS conversion is now only based on codetables.xml.
2087 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2089 --- 2.0.22 2004/08/06
2091 Add support for more "commit changes" in ZOOM (uses Extended Services).
2093 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2096 Yet another small fix for configure of SSL.
2098 --- 2.0.21 2004/05/14
2100 Fix SSL libs for configure when --with-openssl=DIR is given.
2102 --- 2.0.20 2004/05/10
2104 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2106 SSL comstack now uses yaz.pem certificate file on server side
2107 by default. Certificate filename can be configured by calling
2108 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2110 Fix bug regarding multiple calls to ZOOM_connection_connect.
2112 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2114 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2115 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2117 ZOOM now allows inspection of X509 peer certificate for verification.
2118 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2120 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2121 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2122 as "modular" but it simplifies things.
2124 Added cs_get_peer_certificate to that returns peer X509 PEM.
2126 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2127 NULL if SSL is unavailable.
2129 Documentation about MARC decoding tools.
2131 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2133 --- 2.0.19 2004/03/30
2135 Rename CHANGELOG to NEWS to follow GNU style packing.
2137 Fix bug with missing initialization of member in init_diagnostics.
2138 This bug affects threaded version of GFS server.
2140 --- 2.0.18 2004/03/20
2142 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2145 Ensure zlib.dll is packed with Windows install.
2147 --- 2.0.17 2004/03/17
2149 Fix encoding of xsd:string to use text instead of CDATA.
2151 Fix endless loop in CQL parser with unbalanced ".
2153 Use a more compact way to store MARC-8 conversion tables.
2155 --- 2.0.16 2004/03/16 Debian only
2157 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2160 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2165 --- 2.0.15 2004/03/01
2167 Another fix for decoding of XML packed records.
2169 --- 2.0.14 2004/02/25
2171 Fixes for Chunked encoding. White space not ignored after length spec.
2173 Update NS and use default NS for SRW diagnostic elements.
2175 --- 2.0.13 2004/02/23
2177 Implement ZOOM_resultset_cache_reset which resets record cache.
2179 Implement ZOOM_resultset_sort which sorts a result set.
2181 Implement chunked HTTP transfer.
2183 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2185 --- 2.0.12 2004/02/16
2187 Added member 'schema' to bend_explain_rr structure so that backend
2188 can specify explain record identifier. Defaults to Zeerex 2.0.
2190 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2192 --- 2.0.11 2004/02/16
2194 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2197 Added init command for yaz-client which sends "extra" init request.
2199 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2200 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2202 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2204 Make ZOOM error code for "invalid query".
2206 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2208 --- 2.0.10 2004/02/05
2210 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2213 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2215 Added option -p <file> to make Generic Frontend Server to write PID file.
2217 Added option -D to put Generic Frontend Server in background on its own.
2219 Make ZOOM C recognize option "password". If unset, "pass" is used
2220 (for backwards compatibility).
2222 Fixed a bug in Generic Frontend Server that could make it crash if a
2223 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2226 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2227 Must be issued before open, in order to be in effect.
2229 --- 2.0.9-6 2004/01/12 Debian/Windows
2231 Make the SRU server more picky WRT unknown params, etc.
2233 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2235 New YAZ client command, options, that sets Z39.50 options.
2237 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2238 options from a string of tokens (one token for each option bit).
2240 Update SRW diagnostic code messages.
2242 --- 2.0.9-5 2004/01/07 Debian/Windows
2244 Handle user defined stylesheet for SRW/SRU.
2246 --- 2.0.9-4 2004/01/06 Debian/Windows
2248 Fix bug in decoding of Content-Length.
2250 --- 2.0.9-3 2004/01/06 Debian/Windows
2252 Fix a bug with decoding of XML packed records.
2254 --- 2.0.9-2 2004/01/05 Debian only
2256 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2258 Fix bug in SRW/SRU diagnostics decoding.
2260 --- 2.0.9 2004/01/05
2262 Fixed bug in Generic Frontend Server which could drop records exceeding
2263 preferred message size. Reported and fixed by Irina Dijour.
2265 Fixed calculation of package size for structured records in Generic
2266 Frontend Server. Reported and fixed by Irina Dijour.
2268 Fixed namespace for SRW/SRU diagnostics.
2270 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2272 --- 2.0.8 2003/12/22
2274 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2275 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2278 CQL changes to reflect recent changes to the specification:
2279 * Documentation talks about context sets instead of index sets.
2280 * Documentation talks about indexes instead of qualifiers.
2281 * The CQL-to-PQF transformer's configuration file now uses
2282 "index.set.name = <attributes>" instead of the old form
2283 "qualifier.set.name = <attributes>". (Both forms are still
2284 understood but the latter is deprecated.)
2285 * CQL terms with no explicit index specified are now interpreted as
2286 cql.serverChoice instead of srw.serverChoice (which of course
2287 behaves exactly the same.)
2289 --- 2.0.7 2003/12/16
2291 MARC conversion can now generate ISO2709 output in another
2292 character set. yaz-marcdump uses this facility if you invoke it
2295 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2296 functions from there can be used from C++.
2298 --- 2.0.6 2003/12/04
2300 Frontend server now transfers memory from decoded packages to stream
2303 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2304 references to show up.
2306 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2307 the ZOOM Abstract API. The older names for the same options are still
2308 also supported for the benefit of old applications.
2310 ZOOM-C supports "implementationId" and "implementationVersion" options
2311 to go along with "implementationName". These allow the user code to
2312 specify identification strings to be sent to servers.
2313 Add OID for the new ExtLite attribute set.
2315 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2316 as requested/supplid by Ere Maijala <ere@atp.fi>
2318 For generic frontend server, reverse the order of
2319 "toolkit-supplied / application-supplied" strings sent as implementationId,
2320 Name and Version. Also, remove the spaces around the slash. This brings
2321 the GFS in line with the behaviour of ZOOM-C on the client side.
2323 Add function ZOOM_scanset_display_term.
2325 yaz-client shows scan displayTerm if present.
2327 Utility yaz-iconv is now installed by default along with the man page
2330 Extend configure check for OpenSSL to use pkg-config where available (such
2333 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2334 server to specify uid/gid/mask for socket using the format
2335 unix:[user=uid,][group=gid,][umask=mask,]file=path
2336 If file= is omitted the existing format is assumed, e.g.
2338 in which case the mask is 0666 (rw for everybody).
2340 Major restructure of YAZ source. All source in libyaz is in src directory.
2341 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2342 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2344 Added man page for utility yaz-marcdump (used to be called marcdump).
2345 yaz-marcdump is installed by 'make install'.
2347 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2348 of incoming package failed.
2350 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2352 Change prototype of odr_perror: add const to message string.
2354 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2356 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2357 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2358 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2359 DNS lookup. There should not be any compatibility problems with this
2360 assuming that blocking=1 or 0 is used.
2362 Fix bad reference in UNIX comstack in function cs_addrstr.
2364 Fix for compilation on AIX.
2366 The generic front-end server (server/seshigh.c) now supports returning
2367 Init diagnostics to the client in User-information-field, in
2368 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2371 --- 2.0.4 2003/09/04
2373 Allow any CQL relation (not just all,any,exact,scr).
2375 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2376 that features the same UI.
2378 Implemented command update0 in YAZ client which is equivalent to
2379 update but uses old of Ext Update ASN.1.
2381 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2382 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2383 Previously no OID was used for this info.
2385 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2386 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2387 returns 'malformed search term' otherwise.
2389 SortResponse member resultCount now set to NULL in sort handler of
2392 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2395 Add three new utility functions for translating OIDs between various
2396 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2397 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2398 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2399 char *oid_to_dotstring(const int *oid, char *oidbuf);
2400 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2402 Reverted modifications for ES Update definition for z_IU0Update
2403 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2404 is back to YAZ 2.0.2.
2406 String value attributes for CCL parser.
2408 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2409 which their FirstSearch server returns in Init responses, sometimes
2410 carrying useful diagnostic information when Init fails. This has the
2411 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2412 "z39.50/oclcui.asn", where its definition is somewhat different from
2413 what OCLC document on their web-site, as required to interoperate with
2416 Support for anonymous authentication in yaz-client. Use the command
2419 * Fix the OID of the Index Data-local "admin" Extended Service from
2420 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2421 the 1000, which indicates a locally-defined OID, was a mistake.
2423 --- 2.0.3 2003/06/20
2425 Fix CCL directive @case handling so that it affects string match for
2426 both CCL keywords and qualifiers.
2428 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2429 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2430 Decoder has been updated with ASN.1 changes as listed in
2431 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2432 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2433 z_IUUpdate, remains unchanged.
2435 ZOOM_record_get may now return a record in a specific character set.
2436 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2437 "from" is the character set of record as returned by target. "to" is
2438 the character set to be returned. If omitted, "to" is UTF-8.
2440 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2442 New ODR utility, odr_getelement, which returns name of element for
2443 which encoding/decoding failed.
2445 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2446 in cases where a required element was omitted.
2448 Bug fix: some MARC8 sequences were not converted.
2450 New ZOOM option "step" which specifies number of records to be
2451 retrieved in one chunk. Used in conjunction with "start" and "count".
2453 SRW support for yaz-client. Use scheme http: to use it, e.g.
2456 yaz-client no longer does (un)intelligent character set conversions
2457 by default. Can be enabled with charset and marc_charset commands.
2459 xmalloc trace fix for 64-bit systems such as DEC alpha.
2461 Solaris 2.6 compile fix.
2463 New function, cql_strerror() translates SRW error codes, as returned
2464 by cql_transform_error(), into human-readable English strings. Used
2465 in yaz-client diagnostics when appropriate.
2467 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2468 converts it into a type-1 query which is sent to the server. This
2469 makes CQL available for use with all Z-servers, as opposed to the tiny
2470 minority that can handle CQL queries themselves.
2472 --- 2.0.2 2003/04/28
2474 New Debian package layout similar to the Redhat Package layout.
2476 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2477 and search result respectively.
2479 --- 2.0.1 2003/04/25
2481 Redhat package is now several packages: libyaz (runtime libraries),
2482 libyaz-devel (development and documentation, and yaz (utility programs).
2483 Package spec file by Morten Bogeskov.
2485 New member 'schema' in struct bend_fetch_rr which the name of requested
2486 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2487 handler MAY set this to reflect the schema of the returned record.
2489 New member 'display_term' in struct scan_entry. GFS now sets member entries
2490 and allocates scan entries to be filled by user scan handler. In previous
2491 version, entries member was allocated by the scan handler. That still works,
2492 but the GFS will ignore member display_term - assuming it was NOT set by
2493 the handler. The fact that the GFS now allocates the entries both allows
2494 for new members and makes a scan handler easier to write.
2496 Fix CQL lex buffer overflow.
2498 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2499 SRU default recordPacking is string.
2501 SRU protocol support for frontend server.
2503 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2505 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2507 Added scan for the ZOOM shell (zoomsh).
2511 * String Identifers for Schemas (Amendment 5).
2512 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2513 Old definition for schema
2514 Odr_oid *schema; /* OPT */
2519 Z_InternationalString *uri;
2520 #define Z_Schema_oid 1
2521 #define Z_Schema_uri 2
2524 * resultCount parameter to Sort Response (Amendment 1).
2525 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2527 Support for SRW 1.0 over HTTP. This is an optional feature and
2528 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2531 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2532 on the same port. SRW SearchRetrieveRequests are mapped
2533 to bend_init,bend_search,bend_fetch,bend_close.
2535 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2537 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2538 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2540 ZOOM connections are SRW based if schem http is used for hostname
2541 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2542 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2544 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2545 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2546 distance=n, order=true/false, relation=le, prox unit=word. If
2547 n is omitted, distance 1 is used.
2549 Fixed problem with C compiler include path in wrong order.
2551 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2552 on Solaris. Patch from Ko van der Sloot.
2554 New MARC decode API. All new functions operate on a yaz_marc_t
2555 handle. The most important new functions are: yaz_marc_create,
2556 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2557 decode and destroy respectively. Decoder can produce formats
2558 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2559 include/yaz/marcdisp.h.
2561 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2562 to UTF-8, UCS-32, wchar_t or Latin-1.
2564 * Prototypes for yaz_iconv_-functions moved to separate header
2565 include/yaz/yaz-iconv.h.
2567 Make a few private functions 'static' in unix.c. This prevents
2568 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2570 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2571 are set when Init Response is received.
2573 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2574 but returns diagnostic set as well.
2576 New function yaz_strerror which is a portable wrapper for
2577 strerror/strerror_r/GetLastMessage.
2579 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2580 is returned for MARC. If type is "oai", then OAI MARC is returned.
2582 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2585 --- 1.9.2 2002/11/26
2587 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2589 Fix bad race conditions on SIGTERM and terminate gracefully in
2592 Move retrieval (data1) module to Zebra since nobody seems to be
2595 Add GRS-1 render for ZOOM using same format as yaz-client.
2597 --- 1.9.1 2002/10/05
2599 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2601 Fix broken ESpec handling in data1 module.
2603 SGML reader parses comments and makes them part of the data1 tree.
2605 Added several type casts so that YAZ compiles as C++ code.
2607 ZOOM didn't handle PDU encoding failures properly.
2609 Added more Bib-1 diagnostics (approved extensions).
2611 GNU configure: better check for iconv.
2613 More portable use of accept, getpeername. Check for socklen_t. Use
2614 int/size_t if socklen_t is not defined.
2618 PQF parser rejects bad queries - including those with extra
2619 characters in them. PQF parser used to silently ignore that.
2620 Cleaner API for PQF added, which allows you to get detailed
2621 error information for bad queries (see yaz/pquery.h).
2623 Fixed bug in ZOOM_record_get for type "database".
2625 Implemented mini iconv library supporting conversions between
2626 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2628 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2630 --- 1.8.9 2002/08/20
2632 Fixed ZOOM C record cache so that preferredRecordSyntax and
2633 elementSetName is used to check for already fetched records.
2635 --- 1.8.8 2002/08/02
2637 Added three members in bend_initrequest structure to facilitate
2638 character set negotiation.
2640 Fixed a bug in frontend server that could cause indefinite
2641 loops under rare conditions.
2643 Revised character set utilities (charneg.h) so that encoding
2644 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2646 For PQF, directive @term <type> sets term type for Scan/Search.
2647 Here <type> is general, string, numeric, null. The term type
2648 is inherited - just like @attr.
2650 New call odr_set_charset that sets character set conversion for
2651 international-strings on a ODR stream. Prototype is:
2652 int odr_set_charset(ODR o, const char *to, const char *from);
2653 The InternationalString is still represented as C string in YAZ
2654 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2655 won't). On the protocol level, you can use any encoding.
2657 Support for UNIX sockets in ZOOM.
2659 Solaris recv sometimes returns errno == ENOENT. It is treated as
2660 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2662 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2663 both client and server. Code by Morten Bogeskov.
2665 --- 1.8.7 2002/05/22
2667 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2668 that they can be used directly from Visual Basic. You must recompile
2669 your windows APP if you're using ZOOM.
2671 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2672 Commands "lang" and "charset" sets language and character set respectively.
2673 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2674 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2676 Attributes from multiple CCL fields may be OR'ed rather than merged
2677 using directive "@field or". Fields are still merged by default -
2678 equivalent to "@field merge".
2680 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2683 Fixed bug in zget for parameter ExtendedServicesResponse.
2687 --- 1.8.6 2002/03/25
2689 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2691 Client displays USR.1:SearchResult-1 (hits per term).
2693 Additional Search Info for search in Generic Frontend Server.
2695 Fixed CCL parsing of "field=s".
2697 WIN32 installer - using the excellent NSIS software from nullsoft.
2699 Fixed CCL parsing of "field = - <number>".
2701 Added function yaz_marc_decode that decodes MARC for line mode
2702 display or XML (similar to that used by JZKit).
2704 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2705 Z39.50. But ISO/ILL was, however.
2707 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2708 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2710 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2711 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2713 --- 1.8.5 2002/02/03
2715 New YAZ client features: Command completion and new commands:
2716 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2717 Code provided by Jacob Poulsen.
2719 New call oid_trav, that visits all registered OIDs via callback.
2721 Function ZOOM_record_get now returns const char pointer rather than
2722 void pointer. It saves a lot of type casts.
2724 For YAZ client, command "auth" now allows you to set authentication
2725 in IdPass style. It is enabled when three tokens are given - order
2726 is user, group and password.
2728 Fix memory leaks in MARC record handling for ZOOM.
2730 New option for YAZ client, -k <kilobytes> that sets
2731 maximum record size. Similar to -k option for generic frontend
2732 server and yaz-ztest.
2734 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2736 Prefix query parser reports "fail" when bad attribute set is given.
2738 Fix in MARC decoder. Proximity logging. Fix for attribute set
2739 in scan handler for server. Patches by Shigeru Ishida.
2741 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2744 Configure option --with-openssl=<dir> now works when a directory is
2745 specified. Patch provided by Morten Bogeskov.
2747 New option for YAZ client, -u <auth>, that sets authentication.
2749 ZOOM fix: error information was sometimes "missing", since error
2750 was cleared/reset too when it shouldn't.
2752 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2754 --- 1.8.4 2002/01/04
2756 Scan for ZOOM API. New object ZOOM_scanset. New functions
2757 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2758 ZOOM_scanset_destroy.
2760 New ZOOM function, ZOOM_connection_last_event, that returns type
2761 of last event (such as "receive data", "send data", "apdu received",
2764 New ZOOM option, schema, that specifies schema for retrieval.
2766 New CCL feature. Qualifiers can be aliases for one or more
2767 other qualifiers (if more than one is given, OR is used).
2769 ZOOM uses named result sets if target supports it.
2771 Two new YAZ client commands: . (dot, which sources a script of YAZ
2772 client commands), and ! (to execute shell command.). Implemented
2775 Working on Debian packages.
2777 --- 1.8.3 2001/11/19
2779 YAZ client enables named result sets only if target supports it.
2781 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2783 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2784 with key="host" to get same result.
2786 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2787 Function Z3950_resultset_record(s) returns references to records
2788 "owned" by resultset. To become owner use Z3950_record_clone.
2790 Function z_ext_record handles Extended Services. Thanks to
2793 --- 1.8.2 2001/11/12
2795 CCL Parser fix: ignore token comma when dealing with and-lists.
2797 Documentation updates for COMSTACK.
2799 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2800 Changed prototype Z3950_records. For some functions, int parameters
2801 were changed to size_t.
2803 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2806 New MARC decode/display function, marc_display_exl, which properly rejects
2807 non-ISO2709 records. YAZ client uses it.
2809 --- 1.8.1 2001/10/29
2811 Fix bug: local attribute set wasn't set correctly in PQF strings.
2815 * Old Z39.50 codecs no longer supported.
2817 Added ZOOM C binding. See http://zoom.z3950.org/
2819 Renamed states for COMSTACKs to avoid confusion with events.
2821 Implemented cs_look and proper cs_rcvconnect.
2823 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2825 Configure detects POSIX threads on OpenBSD.
2827 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2828 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2830 When error is returned from present handler, non-surrogate diagnostic
2831 is returned in present response (and fetch handler is no longer called).
2833 * Minor adjustments to pquery parser (PQF). Token characters may be
2834 escaped by using backslash (C-style).
2836 PQF parser allows string attribute values to be specified. For @attr,
2837 non-numeric characters after the equal-sign are treated as strings
2838 (e.g. @attr 9=title).
2840 CCL trunction character may be defined (@truncation in file)
2842 * function zget_ExtendedServicesRequest sets waitAction to
2843 waitIfPossible (was wait).
2845 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2848 CCL operator names may be set in field definition files (CCL_bibset).
2849 See ccl/bib1 for an example.
2851 Fixes in ASN.1 compiler for C++ compatibility.
2853 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2854 and "op_or" to avoid conflict with C++.
2856 Fixed problem with GNU readline detection on Redhat 7.0.
2858 Added step-size for Scan backend handler.
2860 Fixed bug that made the frontend server crash when no attribute
2861 set was specified for scan.
2863 Front-end server automatically switches to original working directory
2864 when installed as an NT service. Previously -w had to be specified to
2867 Added extended attributes for retrieval module (data1), so that data1
2868 records carry d1_readXML/SGML attributes. d1_read also supports
2869 null-data rules ( <tag/>)
2871 On UNIX when POSIX threads are available, a separate library libyazthread
2872 is created. Programmers should link with that library and the yaz library
2873 when using threads. The reason for the split was that some applications
2874 on Linux, such as Apache, doesn't work well when using shared objects that
2877 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2878 (or any frontend server) in SSL mode by specifying ssl: followed by
2879 address. Only tested on UNIX.
2881 Added feature for CCL module. Virtual structure s=al or s=ol generates
2882 and-list and or-list respectively instead of phrase search.
2886 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2887 log_mask_str. This was done to avoid name conflicts with other libraries
2888 (such as other PHP extensions).
2890 Added raw OID member for preferred record syntax (request_format_raw)
2891 and returned record syntax (output_format_raw) for backend fetch method.
2893 Config file yaz-config now accepts options so that it returns specific
2894 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2896 Shared library support for UNIX using GNU libtool.
2898 * Modified backend interface. Request/Response struct's replaced by
2899 one read/write C struct. For example bend_fetchrequest and
2900 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2901 Every handler - even search has to be registered in bend_init
2902 handler. This means that the YAZ library no longer refers to
2903 external functions and it makes it possible to make the whole
2904 thing a single DLL/SO.
2906 Added Segment handler for backend server.
2908 Added Zmbol/Zebra administrative functions to YAZ client.
2910 Threaded frontend server on UNIX (when POSIX Threads are available).
2911 Starting the server with option -T enables multi-threading.
2915 Added configure option --enable-comp/disable-comp to control use
2916 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2917 located in sub directory asn.
2919 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2920 in ${exec_prefix}/bin along with the other programs yaz-client and
2923 GNU automake used to maintain makefiles.
2925 Added several OID's.
2927 Changed retrieval module so that we can load records with no abstract
2928 syntax defined. Tagpaths in these records are fully composed of string
2931 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2935 On UNIX, the generated makefile now supports a proper 'make install'.
2936 The prefix can be set via GNU configure to set the install location
2937 (default is /usr/local).
2939 * YAZ programs client and ztest were renamed to yaz-client and
2940 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2941 locations, such as /usr/bin,/usr/local/bin,etc.
2943 * YAZ Header files were moved from include to include/yaz. YAZ Header
2944 files are referred to as include <yaz/log.h> rather than <log.h>.
2945 The YAZ include path (-I ..) is therefore the same as before. Programmers
2946 should update their #include statements or use -Ipath/include/yaz
2947 instead. The main motivation for doing this change is that YAZ header files
2948 can be installed in "standard" locations /usr/include,/usr/local/include
2949 without introducing conflicts, since ALL YAZ header files are stored
2950 in subdirectory yaz (under /usr/include for example).
2952 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2953 rather than project/workspace files. We switched because project files
2954 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2957 Changed name of logging function, logf, to yaz_log, to prevent name
2958 clash with some math-log functions. The YAZ header log.h defines logf
2959 to yaz_log (#define) so there should be no incompatibilities by this
2962 Added bend_start/bend_stop handlers for server. These handler are
2963 called on start/stop of server. For windows they are called whenever
2964 a service is started/stopped.
2966 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2967 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2968 in util/yc.tcl. The auto-generated C code structures are, in a few
2969 cases, incompatible with the old decoders. There are differences in the
2970 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2971 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2972 The preprocessor variable ASN_COMPILED is defined when the compiled
2973 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2974 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2975 wish to use the old encoders/decoders you can specify --disable-yc
2978 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2979 version so that it supports both new - and old version of DB Update
2981 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2982 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2983 change. The name parameter can be set to 0 in which no name is specified
2984 for the construction. The macros odr_implicit and odr_explicit sets name
2985 parameter to zero for the construction involved. New macros
2986 odr_implicit_tag and odr_explicit_tag are similar to the others,
2987 except that a name parameter is added. For programmers' that don't use
2988 ODR they probably only need to change the call to z_APDU and z_External.
2990 Added access control facility by interfacing the TCP wrapper library.
2991 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2992 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2993 name of the daemon and enables the access control as specified in
2994 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2996 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2997 den Dool <H.M.vdnDool@kub.nl>.
2999 Added reference ID parameter to most functions in server API - refer
3000 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3002 Changed name of ccl library to libccl.a (was ccl.a).
3004 Fixed bug in decoder for Explain (Category TargetInfo).
3006 Added support for GNU readline in client. Thanks to Jacob Poulsen
3007 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3009 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3010 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3011 IMPLEMENTATION! This change was made to the development version before
3012 the ZIG decided to retract the amendment. If any users MUST be
3013 compatible with the original Update definition, PLEASE CONTACT US, and
3014 we will include a separate definition corresponding to the old Update
3015 ES. Note that because of the change to the ASN.1 of the
3016 TaskPackageRecordStructure we cannot define a single structure that
3017 will support both versions.
3019 * Added const modifier to buffer parameter for some ODR/BER encoding
3020 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3021 completeWAIS, odr_dumpBER.
3023 Fixed bug in client.c which caused a crash when a scanResponse didn't
3024 contain positionOfTerm.
3026 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3027 * will cause an error in a client if a non-YAZ target sends both a
3028 * list of Scan entries and non-surrogate diagnostics.
3030 Retrieval module enhancements. Tag sets may be typed in the reference
3031 to it. From the .abs-file the "tagset" directive takes a third optional
3032 integer type for the tag set referenced. From a .tag-file the "include"
3033 directive takes a third optional type as well. The old "type" directive
3034 in the tag set itself is still recognized but acts as the default type
3037 Backend interface change. Individual Scan terms returned from bend_scan
3038 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3039 in include/backend.h.
3041 Retrieval module enhancements. Multiple tag sets and attribute sets may
3042 be specified in abstract syntax specs. Revised the error/warning for
3043 logging messages reported by the retrieval module when reading the
3046 Object Identifier system (oid_..) changed. The API is backwards
3047 compatible but the oid-routines now allocates new OID's when needed.
3048 Raw OID's may be specified in oid_getvalbyname.
3050 YAZ now uses GNU configure to generate Makefile(s).
3052 * Minor changes in some of the member names of DeleteResultSetRequest and
3053 DeleteResultSetResponse. See include/proto.h.
3055 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3056 and added member 'languages' in TargetInfo (which was missing).
3058 Changed the way attribute sets are handled in the retrieval
3059 module. These are now cached, just like the abstract syntaxes
3062 Changed YAZ so that it links with compiled ASN.1.
3064 Added Explain-schema definitions and mapping routines. The following
3065 Explain categories have been implemented: AttributeDetails,
3066 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3068 Fixed minor bug in Windows version of Server Library.
3070 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3072 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3074 Added EXTERNAL: UNIverse Resource Report (non-standard).
3076 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3077 ENUMERATED and SET OF.
3079 * Added 'const' to some of the char pointer arguments for the
3080 functions, data1_read_node, data1_getelementbytagname,
3081 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3084 Fixed bug in data1_insert_taggeddata - the last_child member of
3085 parent wasn't initialised.
3087 * Changed data1_read_record and data1_read_node so that the supplied
3088 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3089 doesn't refer to any parts of the "SGML"-buffer.
3091 Fixed bug in server library (Windows version of statserv_remove).
3093 * Changed code so that it compiles as C++. The type definition
3094 of Odr_fun which is a member of Odr_arm was changed. The result is,
3095 that an explicit typecast is needed for the fun pointer when
3096 using Odr_arm - as in:
3097 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3099 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3101 Implemented the new structured date and time definition as approved
3102 by the ZIG. Added schemaId element to the specificTag in Espec-1
3103 (also approved at the last ZIG). Thanks to RVDM.
3105 Added some Object identifiers (RVDM).
3107 Changed the Update Extended Service (RVDM).
3109 Added command "refid" to client which specifies referenceId for
3110 the following requests.
3112 Implemented extended service handling for server. See ztest.c
3113 for an example as well as backend.h. New handlers are registerd
3114 in the Init handler.
3116 * Changed interface for sort in server.
3118 Added new members to statserv_options_block. It allows a server
3119 to read options from another source than just the command line. Thanks
3120 to Charles Woodfield.
3122 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3123 renamed to zboolean. Some C++ compilers complained about the name.
3125 Minor changes to gils.abs. Added index 's' (sort) on title
3126 and date/time-last-modified.
3128 --- 1.4pl2 1998/1/30
3130 Fixed bug in server library regarding inetd mode (-i). This bug
3131 was introduced by release 1.4.
3133 --- 1.4pl1 1998/1/29
3135 Added sort facility in client and backend server interface.
3137 Fixed problem with dependencies in Makefile(s).
3139 Fixed bugs for encoders/decoders of extended services and
3142 Implemented sub-tree feature for schemas. Sub-trees are
3143 referenced in *.abs-files. See explain.abs for an example
3144 of the use of this feature.
3146 Modified bib1.att; local attributes for ANY didn't include
3147 ANY itself (only affects use of the retrieval module).
3149 Fixed bug in plain SGML reader in function data1_read_node:
3150 tags with prefix "var" was incorrectly interpreted as variants.
3152 Added feature "sub-schemas" to enable references to - and definitions
3153 of - group of elements.
3155 * Removed member parent from type data1_element (in data1.h).
3157 Implemented function odr_nullval() that returns the value of
3160 * Removed member num_children from data1_node (in data1.h).
3162 Made NT service interface part of the server library. The
3163 function statserv_main uses the NT service when required and
3164 calls the statserv_start / statserv_close routines.
3166 Routine zget_SearchRequest and zget_PresentRequest fills
3167 resultSetName/Id member with "default" instead of "Default".
3169 Fixed memory leak in server. Request queue member wasn't freed.
3171 Fixed nmem_exit so that memory is freed.
3175 Revised the CCL parser utility to be thread safe.
3177 Added function, oid_ent_to_oid, to replace the function
3178 oid_getoidbyent, which is not thread safe.
3180 * Added nmem_init and nmem_exit to initialize and release
3181 NMEM resources. Function nmem_init should be called once in the
3182 initial thread before NMEM/ODR is used. statserv.c and client.c
3183 have been changed accordingly. The change was necessary to make
3184 NMEM thread safe. The NMEM memory pool is shared amongst threads
3185 in a process. Unix-based applications will still work fine without
3188 Added NT Services interface for the the Z39.50 (statserv) Server.
3189 Refer to the ztest.c source on the usage.
3191 Windows 95/NT port using MSVC5.0. Project files are included in the
3194 * Defined new 'global' handle for the retrieval (data1) system. The
3195 new handled, data1_handle, describes the state of the data1 system.
3196 This handle is passed as first argument to virtually all
3197 data1 related routines. The functions data1_create and data1_destroy
3198 creates and destroys a data1 handle respectively.
3200 Added ODR encode stream member to all backend request structures
3201 init, search, scan etc. This stream should be used to allocate all
3202 memory used for the response when thread safe operation is needed.
3204 Changed the comstack utility, cs_addstr, to be thread safe. The
3205 returned hostname string returned by the function is now part the
3208 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3209 function. The cs_straddr takes a COMSTACK handle as argument, so this
3210 function must be used after cs_create and before bind/connect.
3211 This function is thread safe.
3213 Moved test server to 'ztest' directory - generic server code still
3214 in 'server' directory.
3216 Made prefix query (pquery.c) utility thread safe.
3218 Added new function modifier YAZ_EXPORT to 'export' public DLL
3219 functions when using windows (see include/yconfig.h).
3221 Added definitions to the OID database (util/oid.c) (RVDM).
3223 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3225 Added call to ccl_rpn_delete in client program.
3227 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3228 release of RPN structure.
3230 Added support for C++, headers uses extern "C" for public definitions.
3231 With input from RVDM.
3233 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3234 Thanks to Ronald van der Meer (RVDM).
3236 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3238 Added support for private extensions to the OID database
3239 (oid_setprivateoids()). Thanks to RVDM.
3241 Added optional, physical ANY (key replication)
3243 Fixed null-reference problem in GRS-1 output filter.
3245 Proximity operator added to Prefix Query Format (PQF).
3247 In test client command "base" accepts multiple databases.
3249 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3253 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3255 Smallish bug-fixes in the new encoders/decoders (explain).
3257 Bug fixed in DeleteRequest.
3259 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3261 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3263 Added SOIF syntax (using private OID for now) to retrieval module and client.
3265 Added Update extended service.
3267 Added SearchResult-1 additional info structure.
3269 Added optional CCL (ISO8777) interpreter as separate module. Available
3272 --- 1.2 1996/6/10 (1st anniversary release)
3274 Added Summary record syntax. Lightly tested.
3276 Added OPAC record syntax. Untested.
3278 Added ResourceReport service encoders/decoders. Untested.
3280 Fixed bug in z_Unit - wrong tagging on unitSystem.
3282 Fixed bug in the DiagRecs decoder.
3284 Added options for max PDU size and session timeout to frontend-server.
3286 Added documentation of query-language parsers and other supporting utilities.
3288 [frontend-server] Added Attribute set to the bend_scanrequest API.
3290 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3291 surrogate diagnostics were generated.
3293 [retrieval] Allow multiple local values for attribute.
3295 [retrieval] Allow multiple attributes per element in .abs files. index type.
3297 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3299 --- 1.1pl2 1996/4/10
3301 Minor changes, mostly specific to Zebra's requirements (retrieval)
3305 Repaired bug in frontend server when running multiple listening
3306 endpoints in dynamic mode.
3308 z_External() now won't break if a known, ASN.1 value comes encapsulated
3309 in an octet-string. The value will pass through unmodified in an Odr_oct.
3311 Added a bit of code to the demo client to decode & display
3312 ASN.1-structured records represented in the octet-aligned branch of
3313 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3315 Added z_ext_getentbyref() to the ASN module. Doc updated.
3317 * Completed the SCAN definition in the ASN module. This may break SCAN
3318 code based on older YAZ-versions at compile-time. The fix is easy -
3321 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3322 under the SCAN definition. Remember to initialize this, server-people.
3324 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3325 that this does not extend to ODR and ASN.
3327 Comstack allows insertion of established socket (primarily for
3328 inetd-operation of servers). Doc updated.
3330 Front-end server can now start from the inetd in TCP mode. Doc
3333 --- 1.0pl4 1996/1/24
3337 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3338 the rank and record number.
3340 Adjustments to the frontend server.
3342 Fixed diagnostic BER dumper. It ignored the file argument.
3346 Various changes to retrieval module.
3348 Changed the union discriminators of the protocol files from enums to
3349 ints paired with #defines.
3351 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3354 *Changed operator in the RPN structure to 'roperator', again to avoid a
3357 Fixed problems in Explain decoders/encoders.
3359 --- 1.0pl2 1995/12/6
3361 Memory bug in log module fixed.
3363 --- 1.0pl1 1995/12/5
3365 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3367 Bug in Explain DatabaseInfo module fixed.
3369 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3373 The shift to v1.0 signals that we now consider the *core* functionality
3374 of YAZ reasonably stable (the core being more or less equivalent to
3375 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3376 tested (Explain not at all - though that will happen soonish).
3378 Minor changes to code to support Windows port.
3380 Various minor changes after we're getting to use GRS-1 & co. more.
3382 Added Espec-1 format.
3384 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3385 of the protocol and it cannot be selected when encoding (maps into 'string'
3386 when decoding). Needed to talk to some servers.
3388 Demo client can request simple element set names.
3390 Added Diagnostic Format encoders/decoders.
3392 Added simple Close handling to frontend server (no hooks for resource
3393 reporting yet), and demonstration client.
3395 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3397 --- 1.0b3 1995/08/24
3399 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3400 handled incorrectly when records were requested in the searchResponse. This
3401 will only affect you if you use the frontend-server.
3403 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3404 Test-client will ask for and print GRS1. Ztest will return dummy records
3407 Added Explain encoders/decoders to the service-level API. Untested.
3409 Added Extended Services: Item Order encoders and decoders to the Service-
3410 level API. Untested. We could use a recent copy of the pertinent bits
3411 of the ILL protocol to add those bits.
3413 Added diagnostic format 1 encoders/decoders to the service-level API.
3416 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3417 odr_cons.c, which causes a more correct output.
3419 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3420 was always set to 0 when no records were requested in the searchRequest.
3422 * Added better external-handling. This shouldn't harm old code that
3423 *encodes* externals. It can break code that looks for a
3424 'single-ASN1-type' representation, since those types that are known
3425 are now decoded immediately. Look at the SUTRS sample code in
3426 seshigh.c and client.c. Documentation updated.
3428 Handling of structured records in bend_fetchresponse. Length -1 marks
3429 structured record, type is deduced from format field.
3431 --- 1.0b2 1995/06/27
3432 Fairly quick maintenance release to add SUTRS support.
3434 Fixed handling of SUTRS records in the demonstration client.
3436 * Added format field to the bend_fetchrequest and bend_fetchresponce
3437 structures of the backend API (frontend server). When the record is
3438 returned, the value of the format field is mapped to an OID. The
3439 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3440 of the record. The special value VAL_NONE in the bend_request means
3441 that no specific format was requested by the client. Documentation
3442 updated accordingly. Test server (ztest) will return a fixed dummy
3443 SUTRS record if your client requests SUTRS.
3445 Documentation updated accordingly.
3447 You can now set external libraries and RANLIB support in the top-level
3451 First public release.
