3 New utility z_get_HTTP_Response_details - an extended version of
6 New utility yaz_url_get_error which returns error message of last
7 failed yaz_url_exec call.
9 yaz-url and url functions: allow max HTTP redirects to be controlled.
11 New functions yaz_file_glob2, yaz_xml_include_glob.
12 These functions takes a flags parameter, which, for now only controls
13 whether to fail inclusion of a non-existing file (without glob
14 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
18 For MARC XML parsing, allow record without leader. A fake/default leader
19 is inserted and a warning is tagged with the record.
21 ICU: fix leak in in icu_iter_get_org_info.
25 ICU: fix bug in icu_iter_get_org_info (un-init variable).
29 Implement z_HTTP_header_remove.
33 ICU: Disallow 0 ptrs for some ICU string utilities.
35 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
36 returns original tokens (before normalization).
38 CCL: avoid z39.58/regex truncation when not needed. Apply only the
39 conversion of those masks, when absolutely necessary.
41 CCL: configurable masking character - @mask. Default masking character
44 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
45 full response anyway, so a Transfer-Encoding header will obstruct the
50 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
51 picking a socket. Problem is that some systems has IPV6 support, but
52 we can't create sockets for them, so we pick AF_UNSPEC first.
54 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
55 use content_len to determine resulting Content-Length in HTTP response
56 and NOT Content-Length supplied in headers by user.
58 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
59 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
61 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
64 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
65 with big endian and unsigned char (by default).
69 Fix yaz-client connect (crash in 4.2.55).
73 Fix proxy/host problem for ZOOM that could occur if unix sockets
76 New Debian package libyaz4-dbg.
78 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
79 differently in tcpip_close.
83 Windows installer of YAZ includes YAZ4J as a component.
85 CQL: allow "extra terms" again, by default. Thus, the CQL parser
86 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
87 and earlier. CQL parser may operate in strict mode where queries
88 not conforming to the standard BNF are rejected (syntax error).
89 Whether the CQL parser operates in strict mode is controlled with
90 cql_parser_strict . Strict mode enabled with option -S for utilities
91 cql2pqf and cql2xcql .
93 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
97 New charset, MARC-8c, which is like MARC-8 but allows control characters
98 0x01 through 0x1F, except ESC to be passed through verbatim.
100 Fix a problem with duplicate sub field character in MARC output. Problem
101 happened only when output was MARC-8 encoded.
103 --- 4.2.52 2013/04/03
105 yaz-ztest: Use hash for fake hit count. Before, random number was used.
106 This is problematic for unit tests using yaz-ztest. This patch also makes
107 a hash for CQL queries. For RPN, any term with a leading digit will be
108 treated as pseudu hit count (to force any particular hit count by a client).
110 yaz-ztest: return unique MARC dummy records. Beyond record offset
111 24, the author surname is patched with offset to make all records
114 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
115 on system wide default (/proc/sys/net/ipv6/bindv6only).
116 @4 binds to IPV4 only. @6 binds to IPV6 only.
118 Update CQL API documentation a bit
120 CQL: don't accept extra terms for queries. Makes the CQL parser
121 stricly conformant to the standard.
123 --- 4.2.51 2013/02/12
125 GFS: scan handler gets extra_args from request and may return extra
126 response data . That's for SRU only.
128 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
130 --- 4.2.50 2013/01/30
132 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
134 OPACXML: sync spelling of availabilityDate in XML to that of Schema
135 opaxxml.xsd. The schema had the correct spelling of this member always.
136 The ASN.1 was mis-spelled and still is (API change) - we are
137 not changing this. However, the OPAC to XML conversion had yet
140 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
143 New function, z_ext_record_oid_nmem, which is similar to
144 z_ext_record_oid but takes NMEM rather than ODR
146 --- 4.2.49 2013/01/18
148 ICU: New conversion element 'join' which joins tokens into one
149 with a custom character given by rule attribute.
151 --- 4.2.48 2013/01/10
153 New GFS search member: present_number. This is a hint to the
154 search handler how many records are going to be fetched immediately
155 following search. There's no guarantee that it's going to be the case,
156 since it depends on hit count (for Z39.50 piggyback) and whether errors
159 Make a few functions static (private). The functions getbyte_stream,
160 ungetbyte_stream and yaz_gets are now private. They were never declared
163 yaz-marcdump: exit(5) for serious decoding errors
165 ISO2709 decoding: be more picky WRT header
167 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
168 was only used as to indicate that next-result-set-position should be
170 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
171 Based on patch from Ashley Sanders.
173 Make some functions static/private in PQF parsing. Those functions were
174 never declared in a public header and so should not be in use by
175 applications based on YAZ.
177 --- 4.2.47 2012/11/23
179 ZOOM: special options to control APDU logging.
180 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
181 logging of APDUs until "saveAPDU" option is set again. If logging is
182 already enabled the effect is that current APDU buffer is cleared.
183 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
184 logging (default behavior on new connection).
185 The APDUs sent/received can be obtained by using
186 Using ZOOM_connection_option_get(c, "APDU") or
187 ZOOM_connection_option_getl(c, "APDU", &l).
189 GFS: relay implementation_version from backend
190 From 3.0.40 and later, implementation_version from backend was
191 not used in init response at all.
193 --- 4.2.46 2012/11/15
195 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
196 mode at all. Probably never did.
198 Make a new version of ztest.pem that, at least, is not expired.
200 --- 4.2.45 2012/11/13
202 Fix description of CCL directive 'case'.
204 More tight checking of form arguments (yaz_uri_to_array). Makes
205 YAZ better at rejecting big and/or bad POSTs.
207 SRU decoding does not report more than up to 10 invalid arguments.
209 rpn2cql: less quotes in generated terms. Semantics unchanged, but
210 it's prettier this way.
212 --- 4.2.44 2012/10/25
214 New utility yaz_decode_init_diag. Defined in proto.h.
216 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
217 given for unix local socket.
218 The COMSTACK string for doing so is:
221 unix:/myfile:tcp:localhost:9999/mybase
222 unix:/myfile:localhost:9999/mybase
223 unix:/myfile:http://fakehost/mybase
225 debian: Use dpkg-buildflags in build process.
227 --- 4.2.43 2012/10/19
229 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
230 global's SRU service uses a recordPosition scheme starting from zero.
231 First record's position should be one
232 according to the standard.
234 --- 4.2.42 2012/10/18
236 Allow more namespaces for SRU. This is to allow, for example, an
237 incorrect namespace returned from server
238 http://services.igi-global.com/sru .
240 Minor fixes for compilation on Windows.
242 --- 4.2.41 2012/10/11
244 daemon: log total number of bad signals from child on stop so that it
245 is more easy to spot problems with child worker processes.
247 retrieval: empty backend name attribute omits element set
248 from being used in retrieval.
250 --- 4.2.40 2012/10/04
252 Implement Solr sort strategy "solr", similar to sru11 sorting.
253 This will implement the correct parameters on Solr requst to do
256 --- 4.2.39 2012/09/28
258 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
261 MARC: Extra/missing indicator handled for MARCXML.
262 The indicator length is given in header and is the same for the
263 whole record. If attributes ind1, ind2 are missing, then content
264 character defaults to blank. Extra indicator attributes (beyond)
265 indicator length are treated as an error.
267 Reformat: delete trailing whitespace
269 --- 4.2.38 2012/09/17
271 MARC: fix non-ASCII characters for leader. This is to ensure we can
272 generate XML in UTF-8.
274 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
275 in one node with structure word.
277 --- 4.2.37 2012/09/04
279 yaz-json-parse: JSON output may be pretty printed by using option
282 Increase default value of max message for Z39.50 Init for GFS, ZOOM
283 and yaz-client. Old value was 1 MB. New value is 64 MB.
285 --- 4.2.36 2012/08/22
287 yaz-client: don't display bogus records from SRU servers. Some SRU servers
288 return more records than given by *maximumRecords*. Skipping those in
291 record_render: simplify buffer return handling and fix at least one bad
292 memory reference, that broke the test_embed_record sometimes.
294 Allow http://user:pass@host notation for yaz_url_exec.
296 zoomsh: allow shell command to be executed. Via the system(3) call.
298 yaz_poll: Allow num_fds == 0
300 yaz-client: fix bad encoding of "itemorder item". The itemorder
301 item <no> - command forgot to use length of encoded Item Request
302 package. Error present since YAZ 3.
304 yaz-ztest: fix bad usage of session handle. Bug was introduced when
305 result sets were saved (271a9c83).
307 SRU recordPacking: guess record packing in response rather than looking
308 at the recordPacking element which, OF COURSE, changed semantics in SRU
311 Decode SRU 2.0 responses. The official namespace for responses, according
312 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
313 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
314 nature.com's server, however, usee namespace
315 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
316 we are now using a glob-expr to match up the namespace. ZOOM C and
317 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
318 I can not find a single real example showing the "real" namespace in
319 the documentation from OASIS. The namespace for requests is different
320 from responses, but this is not added to YAZ yet, when we don't encode
323 --- 4.2.35 2012/06/26
325 zoom/record_render: add support for Base64 decoding fo MARC records
326 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
327 which will decode base64 + ISO2709 marc-8 encoded material from text node
330 --- 4.2.34 2012/06/07
332 Add missing definitions ZOOM_resultset_get_facet_field_by_index
333 and ZOOM_resultset_facets_names.
335 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
338 Change APDU dump printing to avoid long leading blanks. For levels 16
339 or larger the level is shown and the indentation is truncated but
340 recursed with modula 8. This makes it still reasonable easy to read
341 - even for nested BER dumps.
343 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
344 return 0 (incomplete package) in case where the BER package was
345 considered too nested (return value of -2).
347 dumpber: lines of level 15 are not indented further. Two spaces per
348 indentation; indentation 15 or more is indented to a fixed indentation
349 and augmented with a level=<no> indication.
351 zoomsh: increase max size of command+args
353 GFS: No limit in RPN buf size in CQL to RPN conversion.
355 --- 4.2.33 2012/05/09
357 New function for daemon utility, yaz_daemon_stop .
359 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
361 --- 4.2.32 2012/04/25
363 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
364 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
366 --- 4.2.31 2012/04/23
368 YAZ daemon utility relays SIGUSR1 to child process.
370 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
371 would result in en empty database list - which in turn would result in
372 encoding failure for search.
374 Fix reading beyond string in yaz_sort_spec.
376 --- 4.2.30 2012/04/11
378 Add two new SRU diagnostics:
379 236: Access to specified database denied
380 1015: Init/AC: Maximum number of simultaneous sessions for Userid
382 Document the very useful ZOOM-C option "apdulog".
384 CQL to RPN: term may be passed through verbatim. This is enabled with
385 truncation.cql . The assumption being that the term is already CQL.
387 --- 4.2.29 2012/03/20
389 record_conv: leader spec may be given for marc element.
390 The leader spec is given as attribute leaderspec for element marc.
391 For example to convert a MARC21 record from MARC-8 to UTF-8:
392 <marc inputformat="marc" outputformat="marc"
393 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
395 record_conv: allow user-XSLT params. For example:
396 <xslt stylesheet="MARC21slim2DC.xsl">
397 <param name="myparameter" value="myvalue"/>
398 <param name="otherparameter" value="othervalue"/>
401 record_conv: fix error handling for missing marc charsets.
403 CQL: fix extra terms in wrong order.
405 --- 4.2.28 2012/03/06
407 record_conv: modify new API for conversion types. The conversion types
408 may be passed in new functions yaz_record_conv_configure_t and
409 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
411 Avoid mixed statement/variable declare; fixes compilation with Visual
414 --- 4.2.27 2012/02/28
416 Add non-standard SRU diagnostic: 235: "Database does not exist".
417 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
418 Update SRU to Bib-1 diagnostic maps accordingly.
420 CCL: add two new diagnostics for unsupported masking. The new
421 diagnostics are: "Embedded truncation not supported" and
422 "Single charcacter mask not supported".
424 --- 4.2.26 2012/02/23
426 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
428 --- 4.2.25 2012/01/11
430 Build YAZ for Ubuntu Oneiric.
432 CCL: allow parantheses for proximity operands. For example CCL query
433 (a) % (b) is now allowed.
435 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
436 marked dead, rather then being destroyed. If not, the session memory is
437 being free'd before the search/scan handler is finished. Also destroy
438 'request' memory in request_release rather than in various places,
439 which resulted in leaks from time to time.
441 --- 4.2.24 2011/12/21
443 cql_sortby_to_sortkeys: honor sort prefix.
445 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
446 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
447 The rpn2cql family of functions now always returns quoted CQL terms.
449 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
451 --- 4.2.23 2011/12/15
453 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
454 sequence is treated as one. For example, &&a=b&&&c& is identical to
457 --- 4.2.22 2011/12/05
459 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
460 APDUs for a connection to a WRBUF.
462 --- 4.2.21 2011/11/23
464 Fix cql_sortby_to_sortkeys. Completely broken before.
466 Make CCL's @truncation work again.
468 --- 4.2.20 2011/11/09
470 New ZOOM connection setting: tproxy. It's like proxy, but does not
471 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
472 to set resolved address + port for a connection outside ZOOM itself.
474 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
476 --- 4.2.19 2011/11/07
478 Fix uninitialized variable in Solr spell support (could cause SEGV
479 for SRU response decoding).
481 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
482 back-end's addinfo through into the ZOOM response addinfo.
484 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
485 they are separated by a colon and a space rather than simply
488 --- 4.2.18 2011/10/28
490 Add support for Solr spell-checking/suggestions through ZOOM.
491 If a Solr target has been configured correctly for spelling-checking
492 and suggestions, these will now be returned on the ResultSet option
493 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
495 --- 4.2.17 2011/09/28
497 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
498 with a flag whether to substitute escape sequences or not.
500 --- 4.2.16 2011/09/22
502 Fix nmem_strsplit_escape to substitute escape char properly.
504 New option for zoomsh -e , which makes it abort on first error and
505 return process exit code to indicate success/failure.
507 YAZ options utility supports special option -- which makes all it treat
508 all following arguments as non-options.
510 --- 4.2.15 2011/09/16
512 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
513 searched if absolute filename is given.
515 Fix conv_xslt() error-reporting when stylesheet is not found.
516 (The value of fullpath is meaningless in this situation.)
518 --- 4.2.14 2011/09/07
520 Fix problem in CQL sort node creation: un-initialized memory.
522 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
523 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
524 CQL sortby depending on whether Type-1 or CQL is actually sent to the
527 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
528 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
530 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
531 will make it possible to use both single-character mask (#) and wildcard (?)
532 in CCL . Throw diagnostic for left truncation because that is not supported
535 --- 4.2.13 2011/09/01
537 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
538 cases using escapes (\-sequences) and masking.
540 PQF parse fix: A trailing backslash followed by end-of-string (\0)
541 would result in a read one byte beyond string.
543 rpn2ccl may use Z39.50 masking for terms (t=z).
545 ICU check fix. Don't include library -lCrun on Solaris, unless present.
547 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
548 not --cppflags (which seeems like an error in icu-config).
550 --- 4.2.12 2011/08/27 RPM package only
552 cql2ccl: fix conversion of terms: operator characters were not
555 --- 4.2.11 2011/08/25 RPM package only
557 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
558 CCL parser will map both # and ? to their regular expression
559 quivalents (. and .*).
561 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
562 of reserved CQL characters.
564 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
565 is, so that they are passed through.
567 --- 4.2.10 2011/08/24
569 ZOOM SRU mode: more aggressive re-connect.
571 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
572 made available as a utility function, declared in <yaz/logrpn.h>
574 rpn2cql_structure() supports proximity nodes (except that the Type-1
575 proximity node's "exclusion" binary is ignored, as there is no way to
576 express that in CQL). Fixes bug #4564.
580 Fix SEGV that could occur if set command of zoomsh was given without
581 value (2nd argument).
583 Fix SEGV that could occur if unsupported transport was given for
584 COMSTACK - say https (when SSL was unavailable).
586 Build yaz-url on Windows too.
590 New utility to get web content. Header is url.h. A command line tool
591 yaz-url is part of the distribution and packages.
593 Fixes for SSL COMSTACK (when gnutls is in use).
595 New functions yaz_base64{encode,decode}. Header is base64.h.
599 ZOOM C includes HTTP response buffer as additional info if it fails
600 to decode the SRU response.
602 Make wrbuf_json_puts available.
606 zoom: throw diagnostic for invalid value for option "sru". Before a
607 bad SRU request was sent.
609 Adding new utility wrbuf_vp_puts.
611 Add cclxmlconfig.obj to win/makefile. It was missing completely.
615 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
616 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
617 redirect was used at the same time.
619 MARC line mode decoding: be less picky about length given - first
620 5 digits of header that is.
622 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
624 Changes to decoding of SRU records: a record with recordPacking=xml is
625 modified with a new root element <yaz_record> if the recordData contains
626 multiple children elements. This is to make the record XML parseable
629 RPN to Solr conversion: encode special characters.
631 Generic Frontend Server: fix uinitialized member, stepSize.
635 Fix a bug in SRU decoding of records.. The database records stored
636 had un-initialized memory, but it would only be seen with yaz_record_render
637 and type_spec="ext" .
639 Fix a bug in ccl_qual_dup introduced in 4.2.3.
643 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
647 Add new utilities to convert from CQL to CCL . These utilities have
648 prefix cql_to_ccl defined in cql.h.
650 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
651 lead to memory heap corruptions when ICU utilities were in use.
655 Make compilation work without Libxml2.
657 yaz-client: remove redundant blanks in display of searchResult-1 term
662 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
663 resulting CQL node (tree) in a new node CQL_NODE_SORT.
665 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
666 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
667 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
668 Note that the CQL sortby spec is only converted when the GFS is already
669 converting from CQL to RPN (cql2rpn element).
671 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
672 specify whether to collapse delimitors or not. The existing nmem_strsplit
673 do collapse (collapse parameter = 1).
675 Windows installer: For NSIS, set InstallDir depending on x86/x64.
677 Rename internal func yaz_use_attribute_create. While non-static, this
678 function is not declared in a public header.
682 Add -lCrun when linking with ICU on Solaris.
684 More quicks character set conversions for OPAC records.
688 fix problem with record_render: records were converted (character set
689 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
693 SRU: add methods for handling DADS SRU-proxy facets.
695 Separate OPAC record character set for ZOOM_record. yaz_record_render
696 allows a character set given as charset=from/opacfrom,to where 'from' is
697 the character set of a bibliographic record, 'opacfrom' is character set
698 of OPAC record and 'to' is the target character set.
702 yaz-client: show may XML format records. Command show followed by 'format'
703 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
706 src/stemmer.c: Avoid using unnamed union. It is not supported by some
709 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
712 Update yaz.spec to operate on both SLES11 / Centos 5.5.
714 RPM: Release includes 'indexdata' name. Use indexdata in release name so
715 this package can be distinguished from other vendors.
717 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
718 as determined by configure
720 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
722 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
723 returns no error and no record, the present request is considered
724 partial (only a subset of the records could be returned by backend), and
725 so it is appropriate to set Present Status to partial-4.
729 Move yaz-config man pages to section 1.
731 More documentation about Solr.
733 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
734 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
735 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
736 peers on some Linux systems. However, in general that does not work
737 so YAZ can not rely on that to work. Debian changed behavior in this
738 respect from Debian lenny to Debian squeeze (still testing as of Oct
740 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
742 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
746 Fix yaz-config output: echo_source not set correctly by configure.
750 Solr Web Service support for yaz-client and ZOOM.
752 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
754 --- 4.0.12 2010/08/17
756 Z39.50 facet support. Facet specifications are passed for search in
757 other-information with ASN.1 as defined in facet.asn and OID
758 .10.1000.81.5 . Facets are expressed as an Attribute list as known
759 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
760 3 is limit (number of entries to get in response). yaz-ztest returns
761 dummy facets if a client asks for them.
763 --- 4.0.11 2010/07/09
765 CCL fixes: bug 2895 and bug 3539.
767 GR1-display: add comma in display - was removed by mistake in
770 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
772 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
774 --- 4.0.10 2010/06/18
776 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
777 result set from a connection. The result set will be on its own
778 thereafter; no operations on it will perform retrievals from a target.
779 Only cached copies are returned.
781 ZOOM C:fix case for HTTP servers responding with Connection:close.
782 Ensure that if there is a current task it is resumed (like fetching
783 more records in a result set) . Bug #3484.
785 PQF parser: use odr_atoi for Odr_int (not atoi)
787 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
788 values that contain any non-digits are treated as string attributes
789 (previously decoding only checked for leading character ([0-9]). PQF
790 encoding: attribute string values are not surrounded by double-quotes.
794 New utility for managing threads - thread_create.h.
796 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
797 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
798 but YAZ' implementation do.
800 Fixes for yaz_cond-functions on Windows 7.
802 DLL export more symbols.
804 zoomsh: show record do NOT render opac.
806 Remove *.la files from Debian and RPM packages.
810 Debian package libyaz-dev depends on libgnutls-dev again (was
811 removed in YAZ 4.0.6, but due to Libtool it is still needed
812 even though yaz-config do not list libgnutls libs).
814 ZOOM: Use only one WRBUF for returning string results for
815 ZOOM_resultset. Reduces memory usage for ZOOM in general.
817 ZOOM: ZOOM_connection do not use a shared pointer to
818 ZOOM_resultset after ZOOM_resultset is destructed by
819 user. Reverts to YAZ 4.0.4 behavior.
823 record-conv: fix problem with at least one XSL conversion -
824 due to probably incorrect usage of XML XSL documents.
828 Fix yaz-config for static mode and the use of SSL (gnutls).
832 Forward decl timeval struct in mutex.h and gettimeofday.h.
834 yaz-config: fix 'static' mode linking.
838 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
839 are wrappers for pthreads or Windows. For Windows these are put in
840 a separate DLL: yaz_cond4.
842 libyaz.la (whole source) is compiled with thread. If thread support
843 is enabled enabled, all source of YAZ is compiled with treading support.
844 This allows core utilities such as yaz_log to use thread facilities.
845 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
846 thread utilities. This commit moves mutex utilities (mutex.c) from
847 libyaz_server.la to libyaz.la.
849 yaz-json-parse displays leading text until error.
853 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
854 patch from Giannis Kosmas.
856 SRU: no longer URL encode SRU database. The URL for an SRU server is
857 a URL and such is alreeady encoded - at least when given with leading
858 http:// or https://. This reverts behavior to YAZ 3.0.50.
860 Support for new MARC XML notation TurboMARC which like MARCXML is a
861 complete representation of MARC/ISO2709.. This one, however, is more
862 compact and allows for faster processing with XSLT. TurboMARC can be
863 used in the marcdisp.h API, from the yaz-marcdump utility and from
866 yaz-ztest can be configured - via the database - to perform certain
867 delays when it performs operations search, present and single record
868 fetch. This allows testers to make yaz-ztest act as a real or even slow
869 Z39.50 server. Refer to the yaz-ztest man pages for details.
873 wrbuf_destroy allows NULL WRBUF passed to it.
875 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
877 Add ZOOM_connection_close.
879 No fixed size buffers for ZOOM shell - bug #3257.
881 tstodr: make it work on s390 platform.
883 New icu iterator-functions. The new icu_iter-functions makes it possible
884 to use ICU chains from many threads.
886 yaz-client: better syntax check for show command.
890 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
893 New simple local-file XML include facility which allows file glob-patterns.
894 Refer to yaz/xml_include.h.
896 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
899 ZOOM_record_get supports new parameter "format" which makes it format XML
902 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
903 JSONText in ECMA-262) is JSONValue, not JSONObject.
907 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
908 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
910 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
911 POSIX/Unix builds .so with major version 4.
913 Remove old LOG_-defines from log.h. They have been obsolete and
914 undefined by default for the last 5 years.
916 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
918 GFS: Remove socket (int *fd) from search_rr handler. The socket
919 descriptor ptr is a facility that allowed a search handler to supply
920 a socket which would serve as a callback - when search was complete.
921 This facility has now been in use for years.
923 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
924 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
925 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
926 returns 'const char *' rather than 'char *. The returned string is
927 read-only and should not be modified by applications. COMSTACK cs_close is
928 now a void function - it no longer returns int. No applications check for
929 the value and the implementations has always returned 0.
931 ZOOM: use size_t for scan hit counts and str size. Functions
932 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
933 occ (hit count) and len (string length) are now of type size_t pointer
934 rather than int pointer. This is to be able to represent large hit counts
935 and to also just to use the proper type for string length (strlen result).
937 New JSON parser. Refer to include/yaz/json.h .
939 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
940 Used to be int in some cases. Many wrbuf_-functions used to return an int
941 indicating some length.. These return values were never used. And so they
944 ODR: odr_malloc, odr_total now takes size_t for size.
946 clone_z_type: fix leak; occurred for encoding failures.
948 --- 3.0.52 2009/12/03
950 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
951 bug was introduced in 3.0.51.
953 --- 3.0.51 2009/12/02
955 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
957 tcpip comstack: fix leak for getaddrinfo.
959 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
960 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
961 Decoding of SRU "path" database is performed by private function
962 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
963 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
965 yaz-client: honor base command for SRU. Change when database setting
966 is applied for SRU and ensure it is kept when a connection is reset.
967 Change also the way errors are displayed or SRU (decoding of packages).
969 --- 3.0.50 2009/11/02
971 Add support for extra request / response data for SRU codecs and GFS.
972 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
973 for extra data response buffer and length. For the GFS, both request
974 and response data (XML) is carried in extra_args and extra_response_data
975 for the search handler. Patch by Ko van der Sloot.
977 ZOOM: For queries that cannot be converted to the specified rpnCharset,
978 ZOOM now returns a diagnostic on the client-side ('invalid query' /
979 10010). This fixes bug #2113.
981 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
982 cmdfile included a 'quit' command that would result in a memory violation.
984 --- 3.0.49 2009/10/01
986 Make a number of functions defined in xmlquery.c static. These have
987 never been declared in a public header file (yaz/xmlquery.h) and was
988 made public by mistake.
990 Improve speed of character conversions (iconv utilities). This makes
991 conversions from MARC-8 faster.
993 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
994 unless type desired is "raw". This will prevent type "xml" from
995 returning ISO2709 .. Which obviously can not be XML parsed.
997 Fix memory leak in ZOOM that would occur if option apdulog was used
998 on a re-used connection.
1000 Frontend server logs HTTP requests.
1002 Frontend server now sends Z39.50 close when it times out (sesssion has
1003 been idle for too long). Versions 2.0.30 and earlier also sent close.
1004 But due to a mistake this was disabled in all versions after that, i.e.
1005 the server would just close the socket immediately.
1007 yaz-client emits a better message when receiving an unrecognised
1008 userInformationField.
1010 Skip zero-length subfields when decoding ISO2709. This rare case happens
1011 if a record has two FS characters in a sequence. Without this patch
1012 there would be a reference beyond char array in using_code_len fragments
1015 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1017 --- 3.0.48 2009/08/28
1019 The show command offered by the zoomsh command now takes a 3d optional
1020 parameter type which is what is passed to ZOOM_record. If the type
1021 argument is omitted, "render" is used.
1023 RPN to CQL conv may use USE string attributes (bug #2978).
1025 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1027 --- 3.0.47 2009/07/08
1029 Function yaz_xml2query allows a diagnostic element in the PQF XML
1030 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1031 code and additional info respectively.
1033 The BER BOOLEAN is now the integral type Odr_bool which still happens
1034 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1035 typedef'd to Odr_int. This is still an integral 'int', but it may be
1036 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1037 ASN-1 compiler as well as programs has been updated to use the new types.
1039 --- 3.0.46 2009/06/08
1041 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1042 only the bibliographic record was rendered. For type=opac, an OPAC
1043 record is only returned if it is present.
1045 iconv: small fix for encoding of advancegreek.
1047 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1049 yaz-client: option auto_reconnect=on really reconnects.
1051 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1053 server: avoid null ptr ref for for yaz_poll errors.
1055 build: fix RPM build for RHEL 5.3.
1057 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1059 --- 3.0.45 2009/03/31
1061 Fixed bug #2709: TCP connect returns Invalid argument.
1063 Fixed compilation for mingw.
1065 Honor charset for raw records (ZOOM_record_get).
1067 Fixed use of errno for threaded mode that was seen on Solaris 10.
1069 Fixed argument passing with blanks in value for Windows Service.
1071 Disable YAZ' own log rotate by default (no 1 GB limit).
1072 The variable l_max_size which specifies the log file limit is set to 0
1073 (DISABLED): This is due to the fact that YAZ is most often deployed using
1074 logrotate. Also YAZ can not perform log rotate because of unsufficient
1075 permissions (setuid).
1077 --- 3.0.44 2009/02/17
1079 List supported encodings in man page for yaz-iconv.
1081 Fixed missing SSL libs for --libs output
1083 Re-established OID record syntax application-xml. Nobody should use it
1084 but we don't want to change soname because of this symbol being absent.
1086 --- 3.0.42 2009/02/02
1088 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1090 Added member named_result_sets for init handler struct for the GFS. This
1091 allows a server to disable named result sets.
1093 Removed OID record syntax application-xml.
1095 Added support for rule-based transliterator for ICU wrapper of YAZ.
1097 Fixed bug #1902: yaz-icu XML output.
1099 Make YAZ checks Emacs friendly.
1101 BITSTRING value shows value. Bug #2346.
1103 ISO2709 decoding: skip control characters from indicator data.
1105 Omit sort key by default in yaz-icu's output.
1107 Allow combined single char options (again) for YAZ' options function.
1109 Utility yaz-marcdump got option to display YAZ version (-V).
1111 Allow YAZ to use ICU 3.4.
1113 Added new ICU test case which illustrates removal of diacritics.
1115 --- 3.0.41 2008/12/29
1117 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1119 --- 3.0.40 2008/12/29
1121 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1124 Fixed bug #2352: yaz-marcdump crashes for certain record.
1126 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1128 Added support for Danmarc2 to UTF-8 conversion.
1130 Added support for ISO5426 to UTF-8 conversion.
1132 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1133 implementation version.
1135 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1137 --- 3.0.38 2008/11/10
1139 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1140 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1142 ZOOM C now interprets databaseName option for ZOOM connection as path
1145 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1147 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1149 Dummy Libxml2 types no longer defined in headers of YAZ'.
1151 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1154 --- 3.0.36 2008/09/26
1156 Various ODR chapter fixes.
1158 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1160 Added missing source for Windows compilation, mutex.c.
1162 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1164 For SRU connections in ZOOM all records up to "count" are now fetched.
1166 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1167 in Windows due to bad error handling for Libxml2.
1169 Added facility for sending arbitrary records (ASN.1 any) using
1170 ZOOM C's Extended service update. Patch by Sam Reynolds.
1172 New options for ZOOM C's connection, logapdu which makes ZOOM log
1175 --- 3.0.34 2008/06/18
1177 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1179 --- 3.0.32 2008/06/12
1181 Fixed memory violation that could occur when decoding UTF-8. This bug
1182 was only present in 3.0.30 of YAZ.
1184 --- 3.0.30 2008/06/06
1186 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1187 GNU TLS is used by default (if found).
1189 yaz-ztest returns OPAC records if a client asks for OPAC.
1191 Improved speed of MARC-8 encoding.
1193 Added support for lossy and loss-less MARC-8 encoding.
1195 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1197 Added new Windows Service wrapper (sc).
1199 yaz-client's itemorder command may now send a file.
1201 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1203 Added new function yaz_log_xml_errors.
1205 Allow (but warn) unknown XML attributes in MARCXML parsing.
1207 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1209 The UTF-8 to MARC-8 conversion now uses a different set of characters
1210 for Greek symbols. Bug #2120.
1212 --- 3.0.26 2008/02/21
1214 Added yaz_daemon (daemon.h).
1216 Fixed bug #2068: pkg-config trouble
1218 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1220 --- 3.0.24 2008/01/28
1222 Document --with-xml2 option.
1224 Added OPAC XML XSD (etc/opacxml.xsd).
1226 Allow glob mask for name attribute in retrieval element for the
1227 generic frontend server's retrieval facility.
1229 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1230 except POLLIN/POLLOUT.
1232 Fixed error handling in cs_listen. Bug #2037.
1234 --- 3.0.22 2008/01/20
1236 Fixed version in yaz/yaz-version.h.
1238 Fixed bug #2027: Crash when closing connection.
1240 Changed configure so that ICU support is only enabled if only ICU
1241 and Libxml2 is available (because the ICU chain is XML based).
1243 --- 3.0.20 2008/01/15
1245 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1246 is built. Only this DLL depends on the ICU runtime.
1248 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1249 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1251 Changed license of CCL module to 'Revised BSD'. After consultation with
1252 remaining members of the original EUROPAGATE consortium, we are re-issuing
1253 the CCL module without a separate license. The software was developed by
1254 Index Data as part of a research project. The special license was included
1255 to help feed usage information back to the project consortium to support
1256 project evaluation. At this time, the project consortium has long-since
1257 disbanded, and the majority of the original principals have retired. At the
1258 same time, we have significantly modified the software during the following
1259 years, to the point where very practically no original code remains. To
1260 simplify re-use of the software, we have contacted those members of the
1261 consortium who could be reached, and agreed to re-issue the module as a
1262 proper part of the YAZ package.
1264 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1266 CQL closer to being version 1.2 compliant. CQL also allows free-form
1267 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1270 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1271 bug could make Extended services handling crash in the ZOOM layer. This
1272 bug was only present in YAZ 3.0.18.
1274 --- 3.0.18 2007/12/19
1276 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1279 yaz-marcdump reads and writes collection wrapped records.
1281 Handle OPAC for record conversion module.
1283 Fixes for ICU wrapper.
1285 Allow ICU libs to be controlled with --with-icu .
1287 --- 3.0.16 2007/11/12
1289 Added yaz_poll which is a wrapper for select/poll. When poll is available
1290 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1291 sockets to be in use.
1293 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1294 functionality through an XML based configuration (ICU chain). This system
1295 is useful for search facilities such as Pazpar2 and Zebra that needs to
1296 perform tokenization of indexed material. The ICU code in a separate
1297 library libyaz3_icu.a.
1299 Added HTTP tunnel facility for COMSTACK, bug #1752.
1300 This is a facility that allows a Web proxy, such as squid, to tunnel
1301 Z39.50 traffic. This facility is "transparent" to must applications
1302 using YAZ. It's enabled by using pseudo transport connect: followed by
1303 the proxy address, followed by command, then follwed by he regular
1304 "virtual" addresss. For example,
1305 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1307 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1309 --- 3.0.14 2007/09/21
1311 Fixed bad memory reference in ZOOM_record - cuased by member not being
1312 initialized. This was a problem only in YAZ 3.0.12.
1314 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1315 fields were not removed.
1317 Changed the way C code is generated from codetables.xml. Made a MARC-8
1318 conversion trie for each characterSet section rather than codeTable.
1319 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1320 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1322 --- 3.0.12 2007/09/12
1324 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1325 from ZOOM_record_error).
1327 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1329 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1331 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1333 Better SRW-to-Bib-1 diagnostic mapping.
1335 ZOOM C and yaz-client announces SRU version 1.2 by default.
1337 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1340 Fixed in yaz_sru_decode to allow other version than 1.1.
1342 --- 3.0.10 2007/08/22
1344 Added support for SRU scan for ZOOM.
1346 Added support for the use of the older versions or Extended Service
1347 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1348 set to the version , 1=first, 2=second, 3=third. The third version is
1349 what ZOOM C has used so far. And that, obviously, is the default.
1351 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1352 therefore in Zebra and in SimpleServer-based applications). The new
1353 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1354 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1355 which is passed into the back-end search callback function.
1357 Added support for HTTP Basic authentication in clients: the SRU/W
1358 codec encodes the username/password elements of the PDU structure
1359 appropriately, and these may be set using the "user" and "password"
1360 options in ZOOM-C applications (the same options that are used for
1361 Z39.50 authentication).
1363 --- 3.0.8 2007/06/25
1365 Fixed bug #1208: SSL appears to be broken in ZOOM.
1367 Fixed bug #1206: Libxml2 include path weirdness.
1369 Added oid_name_to_dotstring.
1371 Allow elementSetName to be specified for ZOOM C record update.
1373 Allow waitAction to be specified for ZOOM C based for Extended Services.
1375 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1376 syntax OID. Bug introduced in YAZ 3 series.
1378 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1380 --- 3.0.6 2007/06/06
1382 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1383 directory. yaz-client now reads commands from file given by option -f
1384 if specified; then tries to read .yazclientrc in current directory.
1385 Failing that, it reads .yazclientrc from user's home directory.
1387 Added support for correlationInfo Note and ID for Record Update via
1390 Added yaz-client command querycharset which specifies character set for
1391 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1392 (termListAndStartPoint).
1394 Charset ISO5428:1984 is an alias for ISO5428-1984.
1396 Implemented a way to perform scan in a result set using Z39.50. This
1397 is achieved by attaching the result set name in the characterInfo
1398 (type InternationalString) of OtherInformation in the Scan Request PDU.
1399 The result set is identified in the otherinformation by the new OID:
1400 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1401 This allows for scan in result set and faceted search . Zebra did some
1402 of this in the APT term using attribute type 8 and value being result
1403 set. Using the OtherInformation approach for this is cleaner and easier
1404 to work with in proxies and the like. This facility can be used in
1405 yaz-client using new command setscan which takes a result set as first
1406 argument, start position (APT) as second.
1408 Changed decoding of SRU XML packed records to deal with servers that
1409 have recordData with XML data with multiple root nodes. Also make
1410 comparison for recordPacking case insensitive. Again, one server
1411 returns "XML" where others return "xml".
1413 For SRU responses allow Content-Type application/xml as well as text/xml.
1415 --- 3.0.4 2007/05/21
1417 Fixed bug in character set conversion of BER strings. Bug introduced
1420 --- 3.0.2 2007/05/08
1422 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1424 For OID class, use oid_class consistently.
1426 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1429 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1430 character set for bibliographic information interchange". By Giannis Kosmas.
1432 Added documentation on new OID API.
1434 --- 3.0.0 2007/05/02
1436 Changes to generic frontend server interface: added new member
1437 'query_charset' for bend_initrequest structure. A backend init handler
1438 should set this member to its native character set for query terms.
1439 When defined, the frontend server logic will announce this character set
1440 to a client if the negotiationModel bit is set by the client. All server
1441 implementors are encouraged to specify this. If a backend server does not
1442 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1444 Added CCL utility to remove terms (stop words) from resulting RPN
1445 tree. This is handled by functions with prefix ccl_stop_words_ .
1447 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1448 terms in RPN queries.
1450 Clean-up the CCL API. Moved some internal structures from ccl.h to
1451 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1452 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1453 This is replaced by ccl_parser_find_str which takes a string instead.
1455 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1456 libyaz.la is the core of YAZ except the generic frontend server and
1457 does not depend on POSIX threads anymore. libyaz_server.la is the
1458 generic frontend server facilities and uses POSIX thread functionality
1459 if available. The libyaz.la no longer depends on POSIX threads because
1460 the number of global structures is limited. NMEM no longer re-uses blocks
1461 between threads ; it simply free's memory immediately but allocates in
1462 "large" chunks as usual. We don't expect any performance penalties
1463 because of this. The yaz_log system is still using a global log_level so
1464 caution must be taken when modifying it with yaz_log_init_.. +
1465 yaz_log_mask_str. This, however, should not cause any trouble because
1466 these functions are called during initialization of application code
1467 anyway. `yaz-config --libs server` returns libs for server applications;
1468 `yaz-config --libs` returns libs for non-server applications.
1470 New OID database - with public definitions in oid_db.h. Removed old OID
1471 database including the head oid.h and definitions such as enum oid_value
1472 and struct oident. The new OID database uses the same string names as
1473 before but the 'protocol' is gone. There are now only two representations
1474 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1475 converts from string to OID; functions with prefix yaz_oid_to_string
1476 converts the other way.
1478 Change to emit_term() in CQL-to-PQF query translation: when a term has
1479 the /regexp relation modifier, do not process it for leading and
1480 trailing "^" and "*", which have quite different meanings in regular
1483 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1484 write handlers no longer carries a 'last' parameter. This will make
1485 yaz_iconv flush "less" characters. A flush is performed by call to
1486 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1488 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1489 removed, because function yaz_query_to_wrbuf does the same.
1491 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1492 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1494 Deprecated MARC utility functions removed.
1496 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1499 Branch split: YAZ_2_1_55_branch
1501 --- 2.1.54 2007/03/16
1503 Fix to ZOOM-C so that transparent reconnection is properly handled on
1504 connections that are in asynchronous mode.
1506 Fixed compilation on OpenBSD 4.0.
1508 Large strings in GRS-1 records are now properly displayed in yaz-client.
1510 Added character conversion support for "advancegreek"; based on patch from
1513 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1514 sequence is met. Before the error was not set so it would be unknown.
1516 Adjust yaz-marcdump MARC reader so that it skips until record separator
1519 --- 2.1.52 2007/03/07
1521 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1522 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1523 fd_set structure used as a bitmask for the FDs to be selected on.
1525 Using ACX_PTHREAD macro to check for POSIX threads.
1527 Fixed have-vsnprintf check.
1529 --- 2.1.50 2007/02/23
1531 Fixes for configure on BSD. Bug #900.
1533 Added snprintf/vsnprintf wrappers for systems that don't have
1534 limits (heavens forbid).
1536 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1537 created before all previous tasks were completed and removed from the
1538 task queue, the new task could be removed by a mistake.
1540 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1542 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1544 Fixed bug #832: Problem with MARC/charset in yaz-client.
1546 Fixed bug #668: save command line history for yaz-client.
1548 Fixed bug #830: pkg-config support.
1550 --- 2.1.48 2007/01/23
1552 Extended ZOOM result set options with two options that may be read by
1553 a client: resultSetStatus and presentStatus with values as specified for
1555 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1557 Fixed bug #827: Using SSL fails on Debian etch.
1559 Fixed bug #826: Weird looking chars for set of MARC records.
1561 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1562 that is treated as an ItemOrder with itemRequest being an XML document
1563 external. The value of "doc" is the content.
1565 Extended the GFS search facility. New member of bend_search_rr
1566 'estimated_hit_count' signals that hits is known to be an estmate
1567 (higher or lower than real hit count). New member 'partial_resultset'
1568 signals that the search was partial (hit count is lower or equal than
1569 real hit count). For Z39.50, the information is stored in resultSetStatus
1570 member of SearchResponse APDU. For SRU, the information is signalled
1571 via SRU diagnostic 59: "Result set created with valid partial results
1574 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1576 --- 2.1.46 2007/01/13
1578 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1580 Added ZOOM_connection_peek_event.
1582 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1583 the following new functions:
1584 ZOOM_event_nonblock, ZOOM_connection_process,
1585 ZOOM_connection_get_{socket,mask,timeout},
1586 ZOOM_connection_fire_event_{timeout,socket}.
1587 The existing blocking event handler, ZOOM_event, is a wrapper for the
1588 + blocking ZOOM_event_sys_{poll,select}.
1590 Implemented function ccl_xml_config which parses XML version of CCL
1591 configuration (bug #798).
1593 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1595 Added timings utility (yaz/timing.h)
1597 --- 2.1.44 2007/01/03
1599 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1602 Fixed bug #779: Rotation of apdu.log fails.
1604 Fixed for character set conversions:
1605 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1606 Honor G1 set in MARC-8 decoding.
1608 --- 2.1.42 2006/12/17
1610 Fixed bug #775: char conversion does not handle Alternative UTF-8
1613 Implemented function yaz_marc_read_line which parses MARC line format
1614 records. There is a wealth of formats out there. So far, this function
1615 reads line records produced by yaz_marc_write_line.
1617 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1618 more generic and easier to remember(!) options: -i format and -o format
1619 which specifies input format and output format respectively - where
1620 format is one of "marc", "marcxml", "line", "marcxchange".
1622 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1623 does not print anything except warnings for records.
1625 For yaz-marcdump, added support for MARC split into files (-s) with a given
1628 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1629 spec, at http://www.loc.gov/standards/sru/record-update/
1630 This has changed the binary layout of the following structs:
1631 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1632 bend_update_rr . Patch by Ko van der Sloot.
1634 Added GFS utility function bend_assoc_is_alive which returns 1 if
1635 association is still alive (client is connected); 0 otherwise (client
1636 closed connection). This allows busy servers to stop working for
1639 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1640 been a separate piece of software. This version of ziffy has been modified
1641 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1643 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1645 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1646 Client code may now interrogate options such as "init_opt_sort" to
1647 find out whether the server claims to support various options.
1649 --- 2.1.40 2006/11/27
1651 Added utilities yaz_{set,get}_esn to set/get element set name from
1654 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1655 of YAZ and has been so since YAZ 2.1.10.
1657 Implemented ZOOM_record_error which returns error information for
1658 record (surrogate diagnostic).
1660 --- 2.1.38 2006/10/31
1662 Updates for SRU Update by Ko van der Sloot:
1663 1. Changed name from "operation" to "action"
1664 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1665 versions in the code, marked as 'backward compatible'.
1666 3. Added diagnostics for SRU Update.
1668 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1670 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1672 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1674 For GFS, fixed problem with SRU diagnostic 'First record position out of
1675 range' being issued for 0 hits.
1677 zoomtst10 part of Windows Build.
1679 --- 2.1.36 2006/10/13
1681 Implemented yaz_filepath_comp which splits a path into file path
1682 components (required by Zebra 2.0.3+).
1684 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1685 BSD inspired license until now so this should not have any real impact on
1686 anybody. See http://www.opensource.org/licenses/bsd-license.php
1688 Fixed bug #687: Missing log lines.
1690 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1693 Fixed bug #689: SRU diagnostics to be added.
1695 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1696 whether a connection is idle (no more work do do).
1698 --- 2.1.34 2006/10/04
1700 Change type of optval from long to int for invocation of setsockopt with
1701 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1703 Added support for specifying the max log file size for the Generic
1704 Frontend Server. The size is given with option -r.
1706 --- 2.1.32 2006/09/21
1708 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1710 --- 2.1.30 2006/09/17
1712 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1715 Fixed bug in Generic Frontend Server that could cause a server to stop
1716 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1718 For the generic frontend server, the maximum record size is used as maximum
1719 size of incoming packages (SRU + Z39.50). The value until was previously
1720 only used in Z39.50 Init negotiation and, later, in a session controlled
1721 sizes of records returned. This is controlled using -k option. It can be
1722 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1724 --- 2.1.28 2006/09/04
1726 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1729 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1731 New option for yaz-marcdump -lpos=value which allows setting a portion
1732 of MARC header to a certain value.
1734 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1736 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1737 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1739 --- 2.1.26 2006/08/15
1741 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1744 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1746 --- 2.1.24 2006/08/08
1748 Fixed MARC ISO2709 encoding routines to deal with character set
1751 Minor changes to GFS logging. Database included in search request log
1754 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1755 cached/multiple records.
1757 Shared libraries are built by default on Unix+configure.
1759 Changed cql2pqf transformation to use a different evaluation order. The
1760 new order is: always, relation, structure, position, truncation, index
1761 and relationModifier. Old order was: always, relation, relationModifier,
1762 structure, index, position, truncation. Note that the the latter ones
1763 override former ones for identical attributes.. The new scheme means that
1764 it is possible to override any existing attribute with a relationModifier.
1765 And also that it is possible to override everything for the index rule
1766 (except the ones listed in relationModifier). No order is perfect but this
1767 one, we believe, covers more real cases.. The "always" should have been
1768 called "default", since the attributes there can be overridden with all
1771 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1772 compilation phase, but also for yaz-config --cflags output. This allows
1773 us to have public headers with Libxml2 stuff in them . It should also,
1774 eventually, make Libxml2 checks redundant in packages using YAZ, such
1777 --- 2.1.22 2006/06/15
1779 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1780 stored in uri, message and details.. Previously diagnostics were stored
1781 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1782 compatibility.. but he's probably the only one affected, so.
1784 Added support for CCL, compiled on the client side, in ZOOM-C. This
1785 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1786 input; the resulting query objects can be used for for searching with
1787 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1789 YAZ' configure searches for OpenSSL by default.
1791 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1792 SL_CTX_use_certificate_file. See
1793 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1794 for more info. Thanks to Ko van der Sloot.
1796 --- 2.1.20 2006/06/02
1798 Bug #600: SRU GET, POST support for yaz-client. Introduced
1799 command 'sru' which selects method SOAP/GET/POST.
1801 Allow missingValueAction to be specified for the sortspec string -
1802 function yaz_sort_spec. By default, the missing value action is null.
1803 Use ! to specify "abort". Use = followed by stringvalue to specify default
1806 Ensured that Present-handler (if defined) is called in GFS before any call to
1807 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1808 searchRetrieve requests.
1810 Documentation for YAZ is now based on the Docbook XML/XSLT using
1811 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1812 is no longer depending on jade/openjade or docbook-to-man scripts.
1813 PDF is no longer part of the distribution - but can optionally be
1814 made using DSSSL/jadetex or FOP.
1816 Added retrieval handling support in Generic Frontend Server to support
1817 conversion between MARC/XML as well as XSLTtransforms. See
1818 etc/yazgfs.xml for an example.
1820 Added Authentication support to Generic Frontend Server in SRU
1821 mode. Authentication using HTTP Basic is supported, as is the use
1822 of 'x-username' and 'x-password' parameters in the request itself.
1824 Added support for a new character set MARC8s identical to MARC8 except
1825 that it converts combined characters to single Unicode characters in the
1826 Latin-1 range (when possible).
1828 --- 2.1.18 2006/04/24
1830 ASN.1 compiler 0.4: generates brief Doxygen file header for
1831 generated .h/.c files.
1833 Utility yaz_iconv now supports conversion to MARC-8.
1835 New facilities for the MARC module. The reading - and writing of
1836 content are separate methods for the yaz_marc_t handle. The following
1837 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1838 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1839 format). Write functions have prefix yaz_marc_write_.. The existing
1840 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1841 available. Removed support for OAI-MARC and simplexml (not the
1842 simplexml from PHP5).
1844 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1845 to be returned for this connection.
1847 --- 2.1.16 2006/03/31
1849 Allow multiple languages and charsets to be specified with
1850 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1851 negcharset iso-8859-1,utf-8
1853 Translation of proximity nodes from CQL into PQF now works.
1855 Moved to automake 1.8, 1.9.
1857 Added function yaz_log_set_handler which allows a log handler to be
1858 installed. This handler will be called for all log messages. Output
1859 to file is also produced; but that can be disabled by passing NULL
1860 fname to yaz_log_init_file.
1862 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1864 For SRW (including GFS), accept application/soap+xml as content-type
1867 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1868 produces NO stylesheet reference even if a default stylesheet is specified
1871 --- 2.1.14 2006/03/14
1873 Updated Windows package to include yazd.dll + yazd.lib for the
1874 Development component.
1876 If the environment variable YAZ_LOG is set, then it is used as a
1877 string indicating the default level of logging to use if not
1878 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1879 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1880 used as before. So, for example, to omit warnings from YAZ logging,
1881 export YAZ_LOG=-warn
1883 cql_transform() now map structure and other attributes before indexes,
1884 so that index-specific structures and other attributes can override
1885 defaults. So now a combination of mapping specifications such as:
1887 index.dc.date = 1=date-modified 4=5
1888 does the right thing.
1890 cql_transform() now also respects the "always" mapping specification,
1891 which establishes an initial set of attributes to be used for all
1892 terms except where overridden by more specific attributes associated
1893 with the index, relation or modifier.
1895 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1896 which mode to use; one of "post", "get" or "soap" (SRW, default).
1898 Fixes for yaz_iconv routines: changed trie-based character set conversions
1899 to use only non-negative values for bit fields due to Sun's C compiler not
1900 supporting negative values.
1902 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1903 sequences where not read correctly. Fix by Rustam Usmanov.
1905 Updated win/makefile to use options, settings which makes things
1906 compile with VS C 2005.
1908 --- 2.1.12 2006/02/01
1910 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1912 In ZOOM socket code, use select instead of poll on MacOSX.
1914 ZOOM-C now support client-side compilation of CQL into RPN that is
1915 sent to the server, enabling CQL to be used against all Z39.50
1916 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1917 ZOOM_query object, and submit it using ZOOM_connection_search().
1918 The CQL-to-RPN translation uses a configuration file, the name of
1919 which must be specified in the Connection's "cqlfile" option.
1921 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1922 function, which takes as its start-term parameter a ZOOM_query object
1923 (which may have had either CQL or RPN set into it).
1926 --- 2.1.10 2005/11/29
1928 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1929 GFS to support this as well. Backend handler, bend_srw_update, does the
1930 update work. Code contributed by Ko van der Sloot.
1932 Allow retrieval of Search Result-1 information in ZOOM by the use of
1933 options that are attached to a result set. ZOOM documentation updated
1936 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1937 UTF-8 conversion. Patch by Raj Patel.
1939 Added option -m to GFS to control formatting of timestamps in log file.
1941 Added 'exit' as synonym for 'quit' in yaz-client
1943 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1944 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1945 for the new members. Patch by Ko van der Sloot.
1947 Added support for SRU POST. It is supported for content-type
1948 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1950 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1951 Instead make the library libyaz.la multi-threaded. Threading as a whole
1952 can still be disabled by configure option --disable-threads. Previosly,
1953 with older GLIBCs there were problems with MT libs under Apache. This
1954 has now been fixed a long time ago.
1956 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1959 CQL module modified to be case insensitive for relations/indexes/operations.
1961 Fixed bug in CQL transform code: incorrect value relationModifieder
1964 Added 'show all' command for yaz-client which retrieves all results
1967 Added new yaz-client, xmles, which takes a (private) OID and
1968 a document to be sent as an extended service request.
1970 Describe new yaz-client commands wait_response and set_auto_wait.
1972 Increase TCP/IP listener backlog from 3 (which I am guessing was
1973 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1974 that the socket will queue as many incoming connections as it's able
1975 to handle ongoing connections. In other words, it will never now
1976 refuse a connection that it would be able to handle merely because
1977 it's not got around to accepting() enough of the pending connections
1978 yet. This is the behaviour anyway under Linux, where the listen()
1979 argument is ignored; but not under BSD and on systems such as
1980 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1981 YAZ-based servers should now be uniform across operating systems in
1984 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1985 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1986 This allows yaz-marcdump to read large MARC batches (>2 GB).
1988 Modified all YAZ source files - except the source which is auto-generated
1989 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1992 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1993 corresponding to the existing *_setl() function. These allow option
1994 values containing arbitrary valuues.
1996 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1997 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1998 except that it returns an indicator of whether or not the sort
1999 criterion was accepted (0 for OK, -1 for invalid).
2001 --- 2.1.8 2005/06/07
2003 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2004 MARC output rather than returning "new" buffer.
2006 yaz-client warns about unknown init options.
2008 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2010 --- 2.1.6 2005/05/24
2012 Added support for SRW sort in Generic Frontend Server. Patch
2013 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2014 sortKeys - or NULL if none is provided.
2016 Fixed bug #307: It was impossible to specify indefinite/no timeout
2017 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2020 Added support for multiple languages and charsets to be specified in
2021 ZOOM. Each charset/language is separated by a blank. If negotiation is
2022 in effect in init-response, Option
2023 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2024 Code based on patch by Vasiliy Osadchuk.
2026 Fixed bug #306: infinite recursion that occurred when calling
2027 yaz_log_level_init as the first call (before other log level or
2030 Fixed bug in scan handling in front end server: if preferred-Position-In-
2031 Response was non-present, a NULL pointer referece was performed.
2033 --- 2.1.4 2005/04/26
2035 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2036 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2037 now defined for all those error codes. So instead of putting 109 in
2038 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2039 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2041 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2044 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2046 Program yaz-client now exits and produces an error message if multiple
2047 Z39.50 servers are specified on the command line (none or one allowed
2050 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2053 --- 2.1.2 2005/03/16
2055 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2057 Fixed bug #272: Preserve spacing for CCL terms.
2059 --- 2.1.0 2005/03/14
2061 Added support for virtual hosts and multiple backend servers for
2062 the YAZ frontend server. The configution is XML based and
2063 support specificition of CQL to RPN mappings and explain information.
2064 See section "Virtual Hosts" in the YAZ manual.
2066 Extended OPAC display utility. OPAC display utility renders
2067 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2068 to supplement yaz_marc_decode_wrbuf.
2070 Fixed a bug in MARC decoder that could caused it to crash for some
2071 invalid MARC records. More diagnostics and warnings where added in
2072 XML output (warnings, etc are stored in comments).
2074 --- 2.0.34 2005/02/08
2076 Fixes for UNIX domain sockets. Bug #261.
2078 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2080 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2081 Added yaz_marc_subfield_str which defines subfield lead string which is
2082 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2083 yaz_marc_endline_str which defines end of fields string used in
2084 YAZ_MARC_LINE format. Default string is newline.
2086 Experimental support for MarcXChange. This format can be produced
2087 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2088 http://www.bs.dk/standards/MarcXchange.xsd
2090 Added yaz-client commands scansize that sets maximum number of
2091 entries to be returned by scan.
2093 --- 2.0.32 2005/01/11
2095 Added support for SRW scan in yaz-client and Generic Frontend Server.
2097 * Added whereInList member to SRW Scan Term.
2099 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2101 Fixed NMEM system to return aligned blocks on the smallest boundaries
2102 that are suitably aligned for all possible types on the particular
2103 architecture YAZ is being built for.
2105 --- 2.0.30 2005/01/04
2107 Fixed numerious warnings that was issued with newer versions of GCC.
2109 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2110 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2113 Make YAZ Generic Frontend Server slightly faster.
2115 Enhance (and reduce) logging for Generic Frontend Server.
2117 Revert YAZ log system so that it flushes every write operation
2118 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2120 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2121 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2122 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2123 will effectively disable old definitions.
2125 --- 2.0.28 2004/11/09
2127 Added yaz_log_time_format which specifies log format using
2130 Added yaz_log_module_level which returns mask for a module. Value
2131 is non-zero mask a if module is enabled; zero if disabled.
2133 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2134 in include/yaz/cql.h.
2136 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2138 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2140 Fixed bug #172: RPM builds does not enable SSL.
2142 Doxyfile.in part of dist. Doxyfile generated by configure.
2144 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2145 are given and the corresponding component does not exist.
2147 Extend CCL documentation in YAZ reference. Describe r=r.
2149 --- 2.0.26 2004/10/01
2151 Fixed MARC->MARCXML conversion to properly deal with
2152 fields, subfields, indicators having non-ASCII characters.
2154 Fixed MARC->MARCXML conversion so that ASCII control characters
2155 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2158 Added YAZ GFS support for conversion from Z39.50 surrogate
2159 diagnostics to SRW surrogate diagnostics.
2161 Bug fix: YAZ GFS did not return schema in explainResponse.
2163 --- 2.0.25 2004/09/30
2165 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2166 now converts recordSchema to elementSetName as well as schema URI.
2168 Fixed bug in COMSTACK that prevented HTTP request packages from being
2171 --- 2.0.24 2004/09/29
2173 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2174 does not require white-space before and after the dash in a range, e.g.
2175 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2178 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2179 due to new GCC removing "redundant" code.
2181 Added yaz-client commands scanpos and scanstep that sets preferred
2182 position and step-size for scan.
2184 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2186 Added CCL utility ccl_qual_buf which parses one or more CCL
2187 spec lines in a buffer.
2189 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2190 of name and value - ignoring empty lines and comments.
2192 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2194 Added odr_get_element_path which returns current element path for an
2195 ODR handle. This utility is useful in error handling or user-defined
2198 Added ODR_PRINT utility odr_set_stream which is is a more generic
2199 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2200 to a write function and pointer to close function. The close function - if
2201 non-NULL - will be called during odr_destroy.
2203 Fixed bug in CCL parser where truncation char was not removed from
2204 right side when truncation=both was in effect.
2206 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2209 --- 2.0.23 2004/08/11
2211 Fix buffer overrun in CQL parser when dealing with proximity (%).
2213 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2214 to UTF-8/UCS conversion is now only based on codetables.xml.
2216 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2218 --- 2.0.22 2004/08/06
2220 Add support for more "commit changes" in ZOOM (uses Extended Services).
2222 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2225 Yet another small fix for configure of SSL.
2227 --- 2.0.21 2004/05/14
2229 Fix SSL libs for configure when --with-openssl=DIR is given.
2231 --- 2.0.20 2004/05/10
2233 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2235 SSL comstack now uses yaz.pem certificate file on server side
2236 by default. Certificate filename can be configured by calling
2237 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2239 Fix bug regarding multiple calls to ZOOM_connection_connect.
2241 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2243 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2244 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2246 ZOOM now allows inspection of X509 peer certificate for verification.
2247 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2249 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2250 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2251 as "modular" but it simplifies things.
2253 Added cs_get_peer_certificate to that returns peer X509 PEM.
2255 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2256 NULL if SSL is unavailable.
2258 Documentation about MARC decoding tools.
2260 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2262 --- 2.0.19 2004/03/30
2264 Rename CHANGELOG to NEWS to follow GNU style packing.
2266 Fix bug with missing initialization of member in init_diagnostics.
2267 This bug affects threaded version of GFS server.
2269 --- 2.0.18 2004/03/20
2271 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2274 Ensure zlib.dll is packed with Windows install.
2276 --- 2.0.17 2004/03/17
2278 Fix encoding of xsd:string to use text instead of CDATA.
2280 Fix endless loop in CQL parser with unbalanced ".
2282 Use a more compact way to store MARC-8 conversion tables.
2284 --- 2.0.16 2004/03/16 Debian only
2286 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2289 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2294 --- 2.0.15 2004/03/01
2296 Another fix for decoding of XML packed records.
2298 --- 2.0.14 2004/02/25
2300 Fixes for Chunked encoding. White space not ignored after length spec.
2302 Update NS and use default NS for SRW diagnostic elements.
2304 --- 2.0.13 2004/02/23
2306 Implement ZOOM_resultset_cache_reset which resets record cache.
2308 Implement ZOOM_resultset_sort which sorts a result set.
2310 Implement chunked HTTP transfer.
2312 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2314 --- 2.0.12 2004/02/16
2316 Added member 'schema' to bend_explain_rr structure so that backend
2317 can specify explain record identifier. Defaults to Zeerex 2.0.
2319 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2321 --- 2.0.11 2004/02/16
2323 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2326 Added init command for yaz-client which sends "extra" init request.
2328 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2329 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2331 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2333 Make ZOOM error code for "invalid query".
2335 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2337 --- 2.0.10 2004/02/05
2339 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2342 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2344 Added option -p <file> to make Generic Frontend Server to write PID file.
2346 Added option -D to put Generic Frontend Server in background on its own.
2348 Make ZOOM C recognize option "password". If unset, "pass" is used
2349 (for backwards compatibility).
2351 Fixed a bug in Generic Frontend Server that could make it crash if a
2352 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2355 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2356 Must be issued before open, in order to be in effect.
2358 --- 2.0.9-6 2004/01/12 Debian/Windows
2360 Make the SRU server more picky WRT unknown params, etc.
2362 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2364 New YAZ client command, options, that sets Z39.50 options.
2366 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2367 options from a string of tokens (one token for each option bit).
2369 Update SRW diagnostic code messages.
2371 --- 2.0.9-5 2004/01/07 Debian/Windows
2373 Handle user defined stylesheet for SRW/SRU.
2375 --- 2.0.9-4 2004/01/06 Debian/Windows
2377 Fix bug in decoding of Content-Length.
2379 --- 2.0.9-3 2004/01/06 Debian/Windows
2381 Fix a bug with decoding of XML packed records.
2383 --- 2.0.9-2 2004/01/05 Debian only
2385 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2387 Fix bug in SRW/SRU diagnostics decoding.
2389 --- 2.0.9 2004/01/05
2391 Fixed bug in Generic Frontend Server which could drop records exceeding
2392 preferred message size. Reported and fixed by Irina Dijour.
2394 Fixed calculation of package size for structured records in Generic
2395 Frontend Server. Reported and fixed by Irina Dijour.
2397 Fixed namespace for SRW/SRU diagnostics.
2399 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2401 --- 2.0.8 2003/12/22
2403 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2404 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2407 CQL changes to reflect recent changes to the specification:
2408 * Documentation talks about context sets instead of index sets.
2409 * Documentation talks about indexes instead of qualifiers.
2410 * The CQL-to-PQF transformer's configuration file now uses
2411 "index.set.name = <attributes>" instead of the old form
2412 "qualifier.set.name = <attributes>". (Both forms are still
2413 understood but the latter is deprecated.)
2414 * CQL terms with no explicit index specified are now interpreted as
2415 cql.serverChoice instead of srw.serverChoice (which of course
2416 behaves exactly the same.)
2418 --- 2.0.7 2003/12/16
2420 MARC conversion can now generate ISO2709 output in another
2421 character set. yaz-marcdump uses this facility if you invoke it
2424 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2425 functions from there can be used from C++.
2427 --- 2.0.6 2003/12/04
2429 Frontend server now transfers memory from decoded packages to stream
2432 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2433 references to show up.
2435 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2436 the ZOOM Abstract API. The older names for the same options are still
2437 also supported for the benefit of old applications.
2439 ZOOM-C supports "implementationId" and "implementationVersion" options
2440 to go along with "implementationName". These allow the user code to
2441 specify identification strings to be sent to servers.
2442 Add OID for the new ExtLite attribute set.
2444 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2445 as requested/supplid by Ere Maijala <ere@atp.fi>
2447 For generic frontend server, reverse the order of
2448 "toolkit-supplied / application-supplied" strings sent as implementationId,
2449 Name and Version. Also, remove the spaces around the slash. This brings
2450 the GFS in line with the behaviour of ZOOM-C on the client side.
2452 Add function ZOOM_scanset_display_term.
2454 yaz-client shows scan displayTerm if present.
2456 Utility yaz-iconv is now installed by default along with the man page
2459 Extend configure check for OpenSSL to use pkg-config where available (such
2462 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2463 server to specify uid/gid/mask for socket using the format
2464 unix:[user=uid,][group=gid,][umask=mask,]file=path
2465 If file= is omitted the existing format is assumed, e.g.
2467 in which case the mask is 0666 (rw for everybody).
2469 Major restructure of YAZ source. All source in libyaz is in src directory.
2470 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2471 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2473 Added man page for utility yaz-marcdump (used to be called marcdump).
2474 yaz-marcdump is installed by 'make install'.
2476 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2477 of incoming package failed.
2479 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2481 Change prototype of odr_perror: add const to message string.
2483 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2485 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2486 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2487 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2488 DNS lookup. There should not be any compatibility problems with this
2489 assuming that blocking=1 or 0 is used.
2491 Fix bad reference in UNIX comstack in function cs_addrstr.
2493 Fix for compilation on AIX.
2495 The generic front-end server (server/seshigh.c) now supports returning
2496 Init diagnostics to the client in User-information-field, in
2497 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2500 --- 2.0.4 2003/09/04
2502 Allow any CQL relation (not just all,any,exact,scr).
2504 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2505 that features the same UI.
2507 Implemented command update0 in YAZ client which is equivalent to
2508 update but uses old of Ext Update ASN.1.
2510 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2511 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2512 Previously no OID was used for this info.
2514 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2515 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2516 returns 'malformed search term' otherwise.
2518 SortResponse member resultCount now set to NULL in sort handler of
2521 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2524 Add three new utility functions for translating OIDs between various
2525 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2526 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2527 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2528 char *oid_to_dotstring(const int *oid, char *oidbuf);
2529 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2531 Reverted modifications for ES Update definition for z_IU0Update
2532 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2533 is back to YAZ 2.0.2.
2535 String value attributes for CCL parser.
2537 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2538 which their FirstSearch server returns in Init responses, sometimes
2539 carrying useful diagnostic information when Init fails. This has the
2540 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2541 "z39.50/oclcui.asn", where its definition is somewhat different from
2542 what OCLC document on their web-site, as required to interoperate with
2545 Support for anonymous authentication in yaz-client. Use the command
2548 * Fix the OID of the Index Data-local "admin" Extended Service from
2549 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2550 the 1000, which indicates a locally-defined OID, was a mistake.
2552 --- 2.0.3 2003/06/20
2554 Fix CCL directive @case handling so that it affects string match for
2555 both CCL keywords and qualifiers.
2557 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2558 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2559 Decoder has been updated with ASN.1 changes as listed in
2560 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2561 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2562 z_IUUpdate, remains unchanged.
2564 ZOOM_record_get may now return a record in a specific character set.
2565 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2566 "from" is the character set of record as returned by target. "to" is
2567 the character set to be returned. If omitted, "to" is UTF-8.
2569 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2571 New ODR utility, odr_getelement, which returns name of element for
2572 which encoding/decoding failed.
2574 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2575 in cases where a required element was omitted.
2577 Bug fix: some MARC8 sequences were not converted.
2579 New ZOOM option "step" which specifies number of records to be
2580 retrieved in one chunk. Used in conjunction with "start" and "count".
2582 SRW support for yaz-client. Use scheme http: to use it, e.g.
2585 yaz-client no longer does (un)intelligent character set conversions
2586 by default. Can be enabled with charset and marc_charset commands.
2588 xmalloc trace fix for 64-bit systems such as DEC alpha.
2590 Solaris 2.6 compile fix.
2592 New function, cql_strerror() translates SRW error codes, as returned
2593 by cql_transform_error(), into human-readable English strings. Used
2594 in yaz-client diagnostics when appropriate.
2596 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2597 converts it into a type-1 query which is sent to the server. This
2598 makes CQL available for use with all Z-servers, as opposed to the tiny
2599 minority that can handle CQL queries themselves.
2601 --- 2.0.2 2003/04/28
2603 New Debian package layout similar to the Redhat Package layout.
2605 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2606 and search result respectively.
2608 --- 2.0.1 2003/04/25
2610 Redhat package is now several packages: libyaz (runtime libraries),
2611 libyaz-devel (development and documentation, and yaz (utility programs).
2612 Package spec file by Morten Bogeskov.
2614 New member 'schema' in struct bend_fetch_rr which the name of requested
2615 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2616 handler MAY set this to reflect the schema of the returned record.
2618 New member 'display_term' in struct scan_entry. GFS now sets member entries
2619 and allocates scan entries to be filled by user scan handler. In previous
2620 version, entries member was allocated by the scan handler. That still works,
2621 but the GFS will ignore member display_term - assuming it was NOT set by
2622 the handler. The fact that the GFS now allocates the entries both allows
2623 for new members and makes a scan handler easier to write.
2625 Fix CQL lex buffer overflow.
2627 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2628 SRU default recordPacking is string.
2630 SRU protocol support for frontend server.
2632 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2634 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2636 Added scan for the ZOOM shell (zoomsh).
2640 * String Identifers for Schemas (Amendment 5).
2641 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2642 Old definition for schema
2643 Odr_oid *schema; /* OPT */
2648 Z_InternationalString *uri;
2649 #define Z_Schema_oid 1
2650 #define Z_Schema_uri 2
2653 * resultCount parameter to Sort Response (Amendment 1).
2654 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2656 Support for SRW 1.0 over HTTP. This is an optional feature and
2657 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2660 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2661 on the same port. SRW SearchRetrieveRequests are mapped
2662 to bend_init,bend_search,bend_fetch,bend_close.
2664 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2666 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2667 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2669 ZOOM connections are SRW based if schem http is used for hostname
2670 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2671 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2673 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2674 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2675 distance=n, order=true/false, relation=le, prox unit=word. If
2676 n is omitted, distance 1 is used.
2678 Fixed problem with C compiler include path in wrong order.
2680 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2681 on Solaris. Patch from Ko van der Sloot.
2683 New MARC decode API. All new functions operate on a yaz_marc_t
2684 handle. The most important new functions are: yaz_marc_create,
2685 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2686 decode and destroy respectively. Decoder can produce formats
2687 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2688 include/yaz/marcdisp.h.
2690 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2691 to UTF-8, UCS-32, wchar_t or Latin-1.
2693 * Prototypes for yaz_iconv_-functions moved to separate header
2694 include/yaz/yaz-iconv.h.
2696 Make a few private functions 'static' in unix.c. This prevents
2697 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2699 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2700 are set when Init Response is received.
2702 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2703 but returns diagnostic set as well.
2705 New function yaz_strerror which is a portable wrapper for
2706 strerror/strerror_r/GetLastMessage.
2708 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2709 is returned for MARC. If type is "oai", then OAI MARC is returned.
2711 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2714 --- 1.9.2 2002/11/26
2716 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2718 Fix bad race conditions on SIGTERM and terminate gracefully in
2721 Move retrieval (data1) module to Zebra since nobody seems to be
2724 Add GRS-1 render for ZOOM using same format as yaz-client.
2726 --- 1.9.1 2002/10/05
2728 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2730 Fix broken ESpec handling in data1 module.
2732 SGML reader parses comments and makes them part of the data1 tree.
2734 Added several type casts so that YAZ compiles as C++ code.
2736 ZOOM didn't handle PDU encoding failures properly.
2738 Added more Bib-1 diagnostics (approved extensions).
2740 GNU configure: better check for iconv.
2742 More portable use of accept, getpeername. Check for socklen_t. Use
2743 int/size_t if socklen_t is not defined.
2747 PQF parser rejects bad queries - including those with extra
2748 characters in them. PQF parser used to silently ignore that.
2749 Cleaner API for PQF added, which allows you to get detailed
2750 error information for bad queries (see yaz/pquery.h).
2752 Fixed bug in ZOOM_record_get for type "database".
2754 Implemented mini iconv library supporting conversions between
2755 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2757 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2759 --- 1.8.9 2002/08/20
2761 Fixed ZOOM C record cache so that preferredRecordSyntax and
2762 elementSetName is used to check for already fetched records.
2764 --- 1.8.8 2002/08/02
2766 Added three members in bend_initrequest structure to facilitate
2767 character set negotiation.
2769 Fixed a bug in frontend server that could cause indefinite
2770 loops under rare conditions.
2772 Revised character set utilities (charneg.h) so that encoding
2773 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2775 For PQF, directive @term <type> sets term type for Scan/Search.
2776 Here <type> is general, string, numeric, null. The term type
2777 is inherited - just like @attr.
2779 New call odr_set_charset that sets character set conversion for
2780 international-strings on a ODR stream. Prototype is:
2781 int odr_set_charset(ODR o, const char *to, const char *from);
2782 The InternationalString is still represented as C string in YAZ
2783 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2784 won't). On the protocol level, you can use any encoding.
2786 Support for UNIX sockets in ZOOM.
2788 Solaris recv sometimes returns errno == ENOENT. It is treated as
2789 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2791 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2792 both client and server. Code by Morten Bogeskov.
2794 --- 1.8.7 2002/05/22
2796 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2797 that they can be used directly from Visual Basic. You must recompile
2798 your windows APP if you're using ZOOM.
2800 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2801 Commands "lang" and "charset" sets language and character set respectively.
2802 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2803 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2805 Attributes from multiple CCL fields may be OR'ed rather than merged
2806 using directive "@field or". Fields are still merged by default -
2807 equivalent to "@field merge".
2809 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2812 Fixed bug in zget for parameter ExtendedServicesResponse.
2816 --- 1.8.6 2002/03/25
2818 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2820 Client displays USR.1:SearchResult-1 (hits per term).
2822 Additional Search Info for search in Generic Frontend Server.
2824 Fixed CCL parsing of "field=s".
2826 WIN32 installer - using the excellent NSIS software from nullsoft.
2828 Fixed CCL parsing of "field = - <number>".
2830 Added function yaz_marc_decode that decodes MARC for line mode
2831 display or XML (similar to that used by JZKit).
2833 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2834 Z39.50. But ISO/ILL was, however.
2836 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2837 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2839 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2840 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2842 --- 1.8.5 2002/02/03
2844 New YAZ client features: Command completion and new commands:
2845 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2846 Code provided by Jacob Poulsen.
2848 New call oid_trav, that visits all registered OIDs via callback.
2850 Function ZOOM_record_get now returns const char pointer rather than
2851 void pointer. It saves a lot of type casts.
2853 For YAZ client, command "auth" now allows you to set authentication
2854 in IdPass style. It is enabled when three tokens are given - order
2855 is user, group and password.
2857 Fix memory leaks in MARC record handling for ZOOM.
2859 New option for YAZ client, -k <kilobytes> that sets
2860 maximum record size. Similar to -k option for generic frontend
2861 server and yaz-ztest.
2863 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2865 Prefix query parser reports "fail" when bad attribute set is given.
2867 Fix in MARC decoder. Proximity logging. Fix for attribute set
2868 in scan handler for server. Patches by Shigeru Ishida.
2870 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2873 Configure option --with-openssl=<dir> now works when a directory is
2874 specified. Patch provided by Morten Bogeskov.
2876 New option for YAZ client, -u <auth>, that sets authentication.
2878 ZOOM fix: error information was sometimes "missing", since error
2879 was cleared/reset too when it shouldn't.
2881 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2883 --- 1.8.4 2002/01/04
2885 Scan for ZOOM API. New object ZOOM_scanset. New functions
2886 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2887 ZOOM_scanset_destroy.
2889 New ZOOM function, ZOOM_connection_last_event, that returns type
2890 of last event (such as "receive data", "send data", "apdu received",
2893 New ZOOM option, schema, that specifies schema for retrieval.
2895 New CCL feature. Qualifiers can be aliases for one or more
2896 other qualifiers (if more than one is given, OR is used).
2898 ZOOM uses named result sets if target supports it.
2900 Two new YAZ client commands: . (dot, which sources a script of YAZ
2901 client commands), and ! (to execute shell command.). Implemented
2904 Working on Debian packages.
2906 --- 1.8.3 2001/11/19
2908 YAZ client enables named result sets only if target supports it.
2910 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2912 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2913 with key="host" to get same result.
2915 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2916 Function Z3950_resultset_record(s) returns references to records
2917 "owned" by resultset. To become owner use Z3950_record_clone.
2919 Function z_ext_record handles Extended Services. Thanks to
2922 --- 1.8.2 2001/11/12
2924 CCL Parser fix: ignore token comma when dealing with and-lists.
2926 Documentation updates for COMSTACK.
2928 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2929 Changed prototype Z3950_records. For some functions, int parameters
2930 were changed to size_t.
2932 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2935 New MARC decode/display function, marc_display_exl, which properly rejects
2936 non-ISO2709 records. YAZ client uses it.
2938 --- 1.8.1 2001/10/29
2940 Fix bug: local attribute set wasn't set correctly in PQF strings.
2944 * Old Z39.50 codecs no longer supported.
2946 Added ZOOM C binding. See http://zoom.z3950.org/
2948 Renamed states for COMSTACKs to avoid confusion with events.
2950 Implemented cs_look and proper cs_rcvconnect.
2952 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2954 Configure detects POSIX threads on OpenBSD.
2956 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2957 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2959 When error is returned from present handler, non-surrogate diagnostic
2960 is returned in present response (and fetch handler is no longer called).
2962 * Minor adjustments to pquery parser (PQF). Token characters may be
2963 escaped by using backslash (C-style).
2965 PQF parser allows string attribute values to be specified. For @attr,
2966 non-numeric characters after the equal-sign are treated as strings
2967 (e.g. @attr 9=title).
2969 CCL trunction character may be defined (@truncation in file)
2971 * function zget_ExtendedServicesRequest sets waitAction to
2972 waitIfPossible (was wait).
2974 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2977 CCL operator names may be set in field definition files (CCL_bibset).
2978 See ccl/bib1 for an example.
2980 Fixes in ASN.1 compiler for C++ compatibility.
2982 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2983 and "op_or" to avoid conflict with C++.
2985 Fixed problem with GNU readline detection on Redhat 7.0.
2987 Added step-size for Scan backend handler.
2989 Fixed bug that made the frontend server crash when no attribute
2990 set was specified for scan.
2992 Front-end server automatically switches to original working directory
2993 when installed as an NT service. Previously -w had to be specified to
2996 Added extended attributes for retrieval module (data1), so that data1
2997 records carry d1_readXML/SGML attributes. d1_read also supports
2998 null-data rules ( <tag/>)
3000 On UNIX when POSIX threads are available, a separate library libyazthread
3001 is created. Programmers should link with that library and the yaz library
3002 when using threads. The reason for the split was that some applications
3003 on Linux, such as Apache, doesn't work well when using shared objects that
3006 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3007 (or any frontend server) in SSL mode by specifying ssl: followed by
3008 address. Only tested on UNIX.
3010 Added feature for CCL module. Virtual structure s=al or s=ol generates
3011 and-list and or-list respectively instead of phrase search.
3015 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3016 log_mask_str. This was done to avoid name conflicts with other libraries
3017 (such as other PHP extensions).
3019 Added raw OID member for preferred record syntax (request_format_raw)
3020 and returned record syntax (output_format_raw) for backend fetch method.
3022 Config file yaz-config now accepts options so that it returns specific
3023 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3025 Shared library support for UNIX using GNU libtool.
3027 * Modified backend interface. Request/Response struct's replaced by
3028 one read/write C struct. For example bend_fetchrequest and
3029 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3030 Every handler - even search has to be registered in bend_init
3031 handler. This means that the YAZ library no longer refers to
3032 external functions and it makes it possible to make the whole
3033 thing a single DLL/SO.
3035 Added Segment handler for backend server.
3037 Added Zmbol/Zebra administrative functions to YAZ client.
3039 Threaded frontend server on UNIX (when POSIX Threads are available).
3040 Starting the server with option -T enables multi-threading.
3044 Added configure option --enable-comp/disable-comp to control use
3045 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3046 located in sub directory asn.
3048 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3049 in ${exec_prefix}/bin along with the other programs yaz-client and
3052 GNU automake used to maintain makefiles.
3054 Added several OID's.
3056 Changed retrieval module so that we can load records with no abstract
3057 syntax defined. Tagpaths in these records are fully composed of string
3060 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3064 On UNIX, the generated makefile now supports a proper 'make install'.
3065 The prefix can be set via GNU configure to set the install location
3066 (default is /usr/local).
3068 * YAZ programs client and ztest were renamed to yaz-client and
3069 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3070 locations, such as /usr/bin,/usr/local/bin,etc.
3072 * YAZ Header files were moved from include to include/yaz. YAZ Header
3073 files are referred to as include <yaz/log.h> rather than <log.h>.
3074 The YAZ include path (-I ..) is therefore the same as before. Programmers
3075 should update their #include statements or use -Ipath/include/yaz
3076 instead. The main motivation for doing this change is that YAZ header files
3077 can be installed in "standard" locations /usr/include,/usr/local/include
3078 without introducing conflicts, since ALL YAZ header files are stored
3079 in subdirectory yaz (under /usr/include for example).
3081 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3082 rather than project/workspace files. We switched because project files
3083 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3086 Changed name of logging function, logf, to yaz_log, to prevent name
3087 clash with some math-log functions. The YAZ header log.h defines logf
3088 to yaz_log (#define) so there should be no incompatibilities by this
3091 Added bend_start/bend_stop handlers for server. These handler are
3092 called on start/stop of server. For windows they are called whenever
3093 a service is started/stopped.
3095 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3096 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3097 in util/yc.tcl. The auto-generated C code structures are, in a few
3098 cases, incompatible with the old decoders. There are differences in the
3099 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3100 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3101 The preprocessor variable ASN_COMPILED is defined when the compiled
3102 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3103 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3104 wish to use the old encoders/decoders you can specify --disable-yc
3107 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3108 version so that it supports both new - and old version of DB Update
3110 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3111 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3112 change. The name parameter can be set to 0 in which no name is specified
3113 for the construction. The macros odr_implicit and odr_explicit sets name
3114 parameter to zero for the construction involved. New macros
3115 odr_implicit_tag and odr_explicit_tag are similar to the others,
3116 except that a name parameter is added. For programmers' that don't use
3117 ODR they probably only need to change the call to z_APDU and z_External.
3119 Added access control facility by interfacing the TCP wrapper library.
3120 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3121 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3122 name of the daemon and enables the access control as specified in
3123 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3125 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3126 den Dool <H.M.vdnDool@kub.nl>.
3128 Added reference ID parameter to most functions in server API - refer
3129 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3131 Changed name of ccl library to libccl.a (was ccl.a).
3133 Fixed bug in decoder for Explain (Category TargetInfo).
3135 Added support for GNU readline in client. Thanks to Jacob Poulsen
3136 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3138 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3139 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3140 IMPLEMENTATION! This change was made to the development version before
3141 the ZIG decided to retract the amendment. If any users MUST be
3142 compatible with the original Update definition, PLEASE CONTACT US, and
3143 we will include a separate definition corresponding to the old Update
3144 ES. Note that because of the change to the ASN.1 of the
3145 TaskPackageRecordStructure we cannot define a single structure that
3146 will support both versions.
3148 * Added const modifier to buffer parameter for some ODR/BER encoding
3149 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3150 completeWAIS, odr_dumpBER.
3152 Fixed bug in client.c which caused a crash when a scanResponse didn't
3153 contain positionOfTerm.
3155 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3156 * will cause an error in a client if a non-YAZ target sends both a
3157 * list of Scan entries and non-surrogate diagnostics.
3159 Retrieval module enhancements. Tag sets may be typed in the reference
3160 to it. From the .abs-file the "tagset" directive takes a third optional
3161 integer type for the tag set referenced. From a .tag-file the "include"
3162 directive takes a third optional type as well. The old "type" directive
3163 in the tag set itself is still recognized but acts as the default type
3166 Backend interface change. Individual Scan terms returned from bend_scan
3167 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3168 in include/backend.h.
3170 Retrieval module enhancements. Multiple tag sets and attribute sets may
3171 be specified in abstract syntax specs. Revised the error/warning for
3172 logging messages reported by the retrieval module when reading the
3175 Object Identifier system (oid_..) changed. The API is backwards
3176 compatible but the oid-routines now allocates new OID's when needed.
3177 Raw OID's may be specified in oid_getvalbyname.
3179 YAZ now uses GNU configure to generate Makefile(s).
3181 * Minor changes in some of the member names of DeleteResultSetRequest and
3182 DeleteResultSetResponse. See include/proto.h.
3184 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3185 and added member 'languages' in TargetInfo (which was missing).
3187 Changed the way attribute sets are handled in the retrieval
3188 module. These are now cached, just like the abstract syntaxes
3191 Changed YAZ so that it links with compiled ASN.1.
3193 Added Explain-schema definitions and mapping routines. The following
3194 Explain categories have been implemented: AttributeDetails,
3195 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3197 Fixed minor bug in Windows version of Server Library.
3199 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3201 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3203 Added EXTERNAL: UNIverse Resource Report (non-standard).
3205 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3206 ENUMERATED and SET OF.
3208 * Added 'const' to some of the char pointer arguments for the
3209 functions, data1_read_node, data1_getelementbytagname,
3210 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3213 Fixed bug in data1_insert_taggeddata - the last_child member of
3214 parent wasn't initialised.
3216 * Changed data1_read_record and data1_read_node so that the supplied
3217 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3218 doesn't refer to any parts of the "SGML"-buffer.
3220 Fixed bug in server library (Windows version of statserv_remove).
3222 * Changed code so that it compiles as C++. The type definition
3223 of Odr_fun which is a member of Odr_arm was changed. The result is,
3224 that an explicit typecast is needed for the fun pointer when
3225 using Odr_arm - as in:
3226 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3228 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3230 Implemented the new structured date and time definition as approved
3231 by the ZIG. Added schemaId element to the specificTag in Espec-1
3232 (also approved at the last ZIG). Thanks to RVDM.
3234 Added some Object identifiers (RVDM).
3236 Changed the Update Extended Service (RVDM).
3238 Added command "refid" to client which specifies referenceId for
3239 the following requests.
3241 Implemented extended service handling for server. See ztest.c
3242 for an example as well as backend.h. New handlers are registerd
3243 in the Init handler.
3245 * Changed interface for sort in server.
3247 Added new members to statserv_options_block. It allows a server
3248 to read options from another source than just the command line. Thanks
3249 to Charles Woodfield.
3251 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3252 renamed to zboolean. Some C++ compilers complained about the name.
3254 Minor changes to gils.abs. Added index 's' (sort) on title
3255 and date/time-last-modified.
3257 --- 1.4pl2 1998/1/30
3259 Fixed bug in server library regarding inetd mode (-i). This bug
3260 was introduced by release 1.4.
3262 --- 1.4pl1 1998/1/29
3264 Added sort facility in client and backend server interface.
3266 Fixed problem with dependencies in Makefile(s).
3268 Fixed bugs for encoders/decoders of extended services and
3271 Implemented sub-tree feature for schemas. Sub-trees are
3272 referenced in *.abs-files. See explain.abs for an example
3273 of the use of this feature.
3275 Modified bib1.att; local attributes for ANY didn't include
3276 ANY itself (only affects use of the retrieval module).
3278 Fixed bug in plain SGML reader in function data1_read_node:
3279 tags with prefix "var" was incorrectly interpreted as variants.
3281 Added feature "sub-schemas" to enable references to - and definitions
3282 of - group of elements.
3284 * Removed member parent from type data1_element (in data1.h).
3286 Implemented function odr_nullval() that returns the value of
3289 * Removed member num_children from data1_node (in data1.h).
3291 Made NT service interface part of the server library. The
3292 function statserv_main uses the NT service when required and
3293 calls the statserv_start / statserv_close routines.
3295 Routine zget_SearchRequest and zget_PresentRequest fills
3296 resultSetName/Id member with "default" instead of "Default".
3298 Fixed memory leak in server. Request queue member wasn't freed.
3300 Fixed nmem_exit so that memory is freed.
3304 Revised the CCL parser utility to be thread safe.
3306 Added function, oid_ent_to_oid, to replace the function
3307 oid_getoidbyent, which is not thread safe.
3309 * Added nmem_init and nmem_exit to initialize and release
3310 NMEM resources. Function nmem_init should be called once in the
3311 initial thread before NMEM/ODR is used. statserv.c and client.c
3312 have been changed accordingly. The change was necessary to make
3313 NMEM thread safe. The NMEM memory pool is shared amongst threads
3314 in a process. Unix-based applications will still work fine without
3317 Added NT Services interface for the the Z39.50 (statserv) Server.
3318 Refer to the ztest.c source on the usage.
3320 Windows 95/NT port using MSVC5.0. Project files are included in the
3323 * Defined new 'global' handle for the retrieval (data1) system. The
3324 new handled, data1_handle, describes the state of the data1 system.
3325 This handle is passed as first argument to virtually all
3326 data1 related routines. The functions data1_create and data1_destroy
3327 creates and destroys a data1 handle respectively.
3329 Added ODR encode stream member to all backend request structures
3330 init, search, scan etc. This stream should be used to allocate all
3331 memory used for the response when thread safe operation is needed.
3333 Changed the comstack utility, cs_addstr, to be thread safe. The
3334 returned hostname string returned by the function is now part the
3337 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3338 function. The cs_straddr takes a COMSTACK handle as argument, so this
3339 function must be used after cs_create and before bind/connect.
3340 This function is thread safe.
3342 Moved test server to 'ztest' directory - generic server code still
3343 in 'server' directory.
3345 Made prefix query (pquery.c) utility thread safe.
3347 Added new function modifier YAZ_EXPORT to 'export' public DLL
3348 functions when using windows (see include/yconfig.h).
3350 Added definitions to the OID database (util/oid.c) (RVDM).
3352 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3354 Added call to ccl_rpn_delete in client program.
3356 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3357 release of RPN structure.
3359 Added support for C++, headers uses extern "C" for public definitions.
3360 With input from RVDM.
3362 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3363 Thanks to Ronald van der Meer (RVDM).
3365 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3367 Added support for private extensions to the OID database
3368 (oid_setprivateoids()). Thanks to RVDM.
3370 Added optional, physical ANY (key replication)
3372 Fixed null-reference problem in GRS-1 output filter.
3374 Proximity operator added to Prefix Query Format (PQF).
3376 In test client command "base" accepts multiple databases.
3378 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3382 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3384 Smallish bug-fixes in the new encoders/decoders (explain).
3386 Bug fixed in DeleteRequest.
3388 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3390 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3392 Added SOIF syntax (using private OID for now) to retrieval module and client.
3394 Added Update extended service.
3396 Added SearchResult-1 additional info structure.
3398 Added optional CCL (ISO8777) interpreter as separate module. Available
3401 --- 1.2 1996/6/10 (1st anniversary release)
3403 Added Summary record syntax. Lightly tested.
3405 Added OPAC record syntax. Untested.
3407 Added ResourceReport service encoders/decoders. Untested.
3409 Fixed bug in z_Unit - wrong tagging on unitSystem.
3411 Fixed bug in the DiagRecs decoder.
3413 Added options for max PDU size and session timeout to frontend-server.
3415 Added documentation of query-language parsers and other supporting utilities.
3417 [frontend-server] Added Attribute set to the bend_scanrequest API.
3419 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3420 surrogate diagnostics were generated.
3422 [retrieval] Allow multiple local values for attribute.
3424 [retrieval] Allow multiple attributes per element in .abs files. index type.
3426 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3428 --- 1.1pl2 1996/4/10
3430 Minor changes, mostly specific to Zebra's requirements (retrieval)
3434 Repaired bug in frontend server when running multiple listening
3435 endpoints in dynamic mode.
3437 z_External() now won't break if a known, ASN.1 value comes encapsulated
3438 in an octet-string. The value will pass through unmodified in an Odr_oct.
3440 Added a bit of code to the demo client to decode & display
3441 ASN.1-structured records represented in the octet-aligned branch of
3442 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3444 Added z_ext_getentbyref() to the ASN module. Doc updated.
3446 * Completed the SCAN definition in the ASN module. This may break SCAN
3447 code based on older YAZ-versions at compile-time. The fix is easy -
3450 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3451 under the SCAN definition. Remember to initialize this, server-people.
3453 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3454 that this does not extend to ODR and ASN.
3456 Comstack allows insertion of established socket (primarily for
3457 inetd-operation of servers). Doc updated.
3459 Front-end server can now start from the inetd in TCP mode. Doc
3462 --- 1.0pl4 1996/1/24
3466 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3467 the rank and record number.
3469 Adjustments to the frontend server.
3471 Fixed diagnostic BER dumper. It ignored the file argument.
3475 Various changes to retrieval module.
3477 Changed the union discriminators of the protocol files from enums to
3478 ints paired with #defines.
3480 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3483 *Changed operator in the RPN structure to 'roperator', again to avoid a
3486 Fixed problems in Explain decoders/encoders.
3488 --- 1.0pl2 1995/12/6
3490 Memory bug in log module fixed.
3492 --- 1.0pl1 1995/12/5
3494 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3496 Bug in Explain DatabaseInfo module fixed.
3498 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3502 The shift to v1.0 signals that we now consider the *core* functionality
3503 of YAZ reasonably stable (the core being more or less equivalent to
3504 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3505 tested (Explain not at all - though that will happen soonish).
3507 Minor changes to code to support Windows port.
3509 Various minor changes after we're getting to use GRS-1 & co. more.
3511 Added Espec-1 format.
3513 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3514 of the protocol and it cannot be selected when encoding (maps into 'string'
3515 when decoding). Needed to talk to some servers.
3517 Demo client can request simple element set names.
3519 Added Diagnostic Format encoders/decoders.
3521 Added simple Close handling to frontend server (no hooks for resource
3522 reporting yet), and demonstration client.
3524 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3526 --- 1.0b3 1995/08/24
3528 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3529 handled incorrectly when records were requested in the searchResponse. This
3530 will only affect you if you use the frontend-server.
3532 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3533 Test-client will ask for and print GRS1. Ztest will return dummy records
3536 Added Explain encoders/decoders to the service-level API. Untested.
3538 Added Extended Services: Item Order encoders and decoders to the Service-
3539 level API. Untested. We could use a recent copy of the pertinent bits
3540 of the ILL protocol to add those bits.
3542 Added diagnostic format 1 encoders/decoders to the service-level API.
3545 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3546 odr_cons.c, which causes a more correct output.
3548 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3549 was always set to 0 when no records were requested in the searchRequest.
3551 * Added better external-handling. This shouldn't harm old code that
3552 *encodes* externals. It can break code that looks for a
3553 'single-ASN1-type' representation, since those types that are known
3554 are now decoded immediately. Look at the SUTRS sample code in
3555 seshigh.c and client.c. Documentation updated.
3557 Handling of structured records in bend_fetchresponse. Length -1 marks
3558 structured record, type is deduced from format field.
3560 --- 1.0b2 1995/06/27
3561 Fairly quick maintenance release to add SUTRS support.
3563 Fixed handling of SUTRS records in the demonstration client.
3565 * Added format field to the bend_fetchrequest and bend_fetchresponce
3566 structures of the backend API (frontend server). When the record is
3567 returned, the value of the format field is mapped to an OID. The
3568 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3569 of the record. The special value VAL_NONE in the bend_request means
3570 that no specific format was requested by the client. Documentation
3571 updated accordingly. Test server (ztest) will return a fixed dummy
3572 SUTRS record if your client requests SUTRS.
3574 Documentation updated accordingly.
3576 You can now set external libraries and RANLIB support in the top-level
3580 First public release.
