3 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
8 Make cs_parse_host public.A
10 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
11 introduced in YAZ 5.0.6.
15 Fix buffer corruption for yaz-ztest record fetch.
19 Allow yaz-ztest to return user-defined records (one record per file).
20 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
22 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
23 Use the stream write instead of odr_printf which has a 4K tmp buffer.
25 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
29 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
30 can read and write this format. For record format JSON, yaz-ztest returns
33 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
34 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
38 Improve error reporting for ICU chains YAZ-707
39 Report config element+rule when ICU status is "failure".
41 ZOOM: stop fetching if present response has no records YAZ-710
42 Some targets return less records than their hit count would suggest.
43 This prevents ZOOM from continuing to fetch records if any present
44 response has 0 records in the response.
46 Ensure that GFS calls exit if any listener fails YAZ-710
47 Before, if XML config was in use, it would start the default
52 yaz-ztest: -V shows version (like yaz-client -V)
54 New iconv encoding: danmarc YAZ-692
56 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
58 daemon: only wait for immediate child rather than all children. YAZ-704
60 yaz-client: fix setting of SRU record schema. If scheme was unset, it
61 could lead to invalid memory reference.
65 yaz-ztest returns schema for MARCXML test records. SRU require that
66 recordSchema for records.
68 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
69 instead of non-surrogate diagnostic. This is a per-record failure.
71 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
72 may refer to multiple listeners now. Attribute listenref is a comma separated
75 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
76 option is given for GFS, the dirname of filename (for -f) is used
77 as prefix for options such as cql2rpn, ccl2rpn, etc.
79 Content-Type charset fixes YAZ-701 . Do not inspect charset in
80 Content-Type header for SOAP when decoding SRU. The payload (XML)
81 itself tells what encoding it is. In response, never supply encoding
82 in Content-Type. The response payload (XML) tells what it is (with no
83 encoding in XML it's UTF-8).
85 HTTP decoding: allow blanks in URL paths YAZ-700
89 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
90 and facets. Ensure recordData and recordSchema are always present in
91 record element, because they are required.
93 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
96 Simplify in a lot of places using odr_strdupn.
98 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
102 Increase various buffers in GFS's statserv_options_block
103 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
104 This change makes many type-casts redundant, and, thus simplifies code.
106 Remove last bits of WAIS support.
108 Remove member 'size' from Odr_oct.
110 Slim down the public part of 'struct odr'. Most elements are not part
111 of struct Odr_private.
113 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
114 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
115 In particular facets are supported in both client - and server side.
116 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
117 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
118 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
119 both request/response). This is what a search handler in the GFS
120 will see (regardless of whether operating in SRU mode or Z39.50).
122 Changes to the srw.h (SRU/Solr) definitions include:
123 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
124 (char*), which replace union query and query_type (int). This is because
125 SRU 2.0 supports a queryType parameter. This also means that, to carry
126 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
127 x-pquery=PQFstring (extention parameter). The extension parameter
129 - New element, packing, that has information about SRU
130 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
132 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
134 New element, packing, in Z_SRW_explainRequest.
136 New elements in Z_SRW_scanRequest, queryType and scanClause.
137 These replace query_type and scanClase untion. This is similar to what
140 --- 4.2.69 2013/10/01
142 GFS: log when closing down - at least SIGTERM YAZ-684
143 Also change formatting WRT PID logging a bit.
145 Improve display of MARC records with multi-byte subfield IDs YAZ-695
146 In some rare cases subfield identifiers are multi-byte characters.
147 This will try to deterime length of those and split accordingly.
148 This affects display in line mode as MARCXML/MarcXchange. The encoding
149 of ISO2709 is the same.
151 Change inp argument to const for yaz_read_UTF8_char.
153 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
155 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
157 Better check of marc leader info YAZ-691
158 Problem is that some systems generate MARCXML/MarcXchange with
159 funny headers. These will not work if encoded as ISO2709.
160 Some tests produce new output, due to updated warning messages
162 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
164 yaz-client: display MAB records YAZ-689.
165 Thanks for Heiko Jansen for this patch.
167 New utility z_get_HTTP_Response_server which allows both HTTP server name
168 and HTTP server URL to be given in response.
170 Debian: do not depend on obs tcl8.3.
172 Debian: do not depend on obs libicu36-dev.
174 --- 4.2.68 2013/09/23
176 GFS: pass additionalSearchInfo to search memeber search_input if
177 given. Otherwise pass otherInfo. Request for facets and other search
178 related things will be passed there in future versions of YAZ.
180 New ZOOM setting, authenticationMode, which allows authentication
181 paramters to be encoded in the URL rather than via HTTP Basic auth.
184 rpn2solr: fix nested AND/OR handling. YAZ-685
186 Add comparison routines for some Z-types, such as NamePlusRecord,
187 RPNQuery, Query, RecordComposition and OtherInformation.
189 --- 4.2.67 2013/09/19
191 Don't decode MAB as MARC. Just like we don't attempt to decode
192 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
194 CCL: allow quoted terms for date ranges. YAZ-681
196 Introduce ccl_parser_qual_search. This function makes old function
197 ccl_qual_search, from YAZ 2, available again.
199 Add yaz_facet_list_to_wrbuf. YAZ-683
201 --- 4.2.66 2013/09/11
203 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
204 schema was given for search. YAZ-675
206 Add Solr date range searches. YAZ-621
208 --- 4.2.65 2013/08/22
210 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
212 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
214 ISO2709/MARC parse most octet aligned records; not just those that
215 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
216 MARC parse more records instead of just dumping as is. YAZ-670
218 ZOOM: proper caching for variations of record schema. YAZ-671
220 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
222 --- 4.2.63 2013/07/17
226 --- 4.2.62 2013/07/11
228 New utility z_get_HTTP_Response_details - an extended version of
231 New utility yaz_url_get_error which returns error message of last
232 failed yaz_url_exec call.
234 yaz-url and url functions: allow max HTTP redirects to be controlled.
236 New functions yaz_file_glob2, yaz_xml_include_glob.
237 These functions takes a flags parameter, which, for now only controls
238 whether to fail inclusion of a non-existing file (without glob
239 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
241 --- 4.2.61 2013/06/20
243 For MARC XML parsing, allow record without leader. A fake/default leader
244 is inserted and a warning is tagged with the record.
246 ICU: fix leak in in icu_iter_get_org_info.
248 --- 4.2.60 2013/06/14
250 ICU: fix bug in icu_iter_get_org_info (un-init variable).
252 --- 4.2.59 2013/06/11
254 Implement z_HTTP_header_remove.
256 --- 4.2.58 2013/06/11
258 ICU: Disallow 0 ptrs for some ICU string utilities.
260 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
261 returns original tokens (before normalization).
263 CCL: avoid z39.58/regex truncation when not needed. Apply only the
264 conversion of those masks, when absolutely necessary.
266 CCL: configurable masking character - @mask. Default masking character
269 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
270 full response anyway, so a Transfer-Encoding header will obstruct the
273 --- 4.2.57 2013/05/15
275 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
276 picking a socket. Problem is that some systems has IPV6 support, but
277 we can't create sockets for them, so we pick AF_UNSPEC first.
279 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
280 use content_len to determine resulting Content-Length in HTTP response
281 and NOT Content-Length supplied in headers by user.
283 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
284 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
286 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
289 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
290 with big endian and unsigned char (by default).
292 --- 4.2.56 2013/04/26
294 Fix yaz-client connect (crash in 4.2.55).
296 --- 4.2.55 2013/04/26
298 Fix proxy/host problem for ZOOM that could occur if unix sockets
301 New Debian package libyaz4-dbg.
303 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
304 differently in tcpip_close.
306 --- 4.2.54 2013/04/17
308 Windows installer of YAZ includes YAZ4J as a component.
310 CQL: allow "extra terms" again, by default. Thus, the CQL parser
311 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
312 and earlier. CQL parser may operate in strict mode where queries
313 not conforming to the standard BNF are rejected (syntax error).
314 Whether the CQL parser operates in strict mode is controlled with
315 cql_parser_strict . Strict mode enabled with option -S for utilities
316 cql2pqf and cql2xcql .
318 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
320 --- 4.2.53 2013/04/10
322 New charset, MARC-8c, which is like MARC-8 but allows control characters
323 0x01 through 0x1F, except ESC to be passed through verbatim.
325 Fix a problem with duplicate sub field character in MARC output. Problem
326 happened only when output was MARC-8 encoded.
328 --- 4.2.52 2013/04/03
330 yaz-ztest: Use hash for fake hit count. Before, random number was used.
331 This is problematic for unit tests using yaz-ztest. This patch also makes
332 a hash for CQL queries. For RPN, any term with a leading digit will be
333 treated as pseudu hit count (to force any particular hit count by a client).
335 yaz-ztest: return unique MARC dummy records. Beyond record offset
336 24, the author surname is patched with offset to make all records
339 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
340 on system wide default (/proc/sys/net/ipv6/bindv6only).
341 @4 binds to IPV4 only. @6 binds to IPV6 only.
343 Update CQL API documentation a bit
345 CQL: don't accept extra terms for queries. Makes the CQL parser
346 stricly conformant to the standard.
348 --- 4.2.51 2013/02/12
350 GFS: scan handler gets extra_args from request and may return extra
351 response data . That's for SRU only.
353 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
355 --- 4.2.50 2013/01/30
357 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
359 OPACXML: sync spelling of availabilityDate in XML to that of Schema
360 opaxxml.xsd. The schema had the correct spelling of this member always.
361 The ASN.1 was mis-spelled and still is (API change) - we are
362 not changing this. However, the OPAC to XML conversion had yet
365 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
368 New function, z_ext_record_oid_nmem, which is similar to
369 z_ext_record_oid but takes NMEM rather than ODR
371 --- 4.2.49 2013/01/18
373 ICU: New conversion element 'join' which joins tokens into one
374 with a custom character given by rule attribute.
376 --- 4.2.48 2013/01/10
378 New GFS search member: present_number. This is a hint to the
379 search handler how many records are going to be fetched immediately
380 following search. There's no guarantee that it's going to be the case,
381 since it depends on hit count (for Z39.50 piggyback) and whether errors
384 Make a few functions static (private). The functions getbyte_stream,
385 ungetbyte_stream and yaz_gets are now private. They were never declared
388 yaz-marcdump: exit(5) for serious decoding errors
390 ISO2709 decoding: be more picky WRT header
392 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
393 was only used as to indicate that next-result-set-position should be
395 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
396 Based on patch from Ashley Sanders.
398 Make some functions static/private in PQF parsing. Those functions were
399 never declared in a public header and so should not be in use by
400 applications based on YAZ.
402 --- 4.2.47 2012/11/23
404 ZOOM: special options to control APDU logging.
405 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
406 logging of APDUs until "saveAPDU" option is set again. If logging is
407 already enabled the effect is that current APDU buffer is cleared.
408 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
409 logging (default behavior on new connection).
410 The APDUs sent/received can be obtained by using
411 Using ZOOM_connection_option_get(c, "APDU") or
412 ZOOM_connection_option_getl(c, "APDU", &l).
414 GFS: relay implementation_version from backend
415 From 3.0.40 and later, implementation_version from backend was
416 not used in init response at all.
418 --- 4.2.46 2012/11/15
420 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
421 mode at all. Probably never did.
423 Make a new version of ztest.pem that, at least, is not expired.
425 --- 4.2.45 2012/11/13
427 Fix description of CCL directive 'case'.
429 More tight checking of form arguments (yaz_uri_to_array). Makes
430 YAZ better at rejecting big and/or bad POSTs.
432 SRU decoding does not report more than up to 10 invalid arguments.
434 rpn2cql: less quotes in generated terms. Semantics unchanged, but
435 it's prettier this way.
437 --- 4.2.44 2012/10/25
439 New utility yaz_decode_init_diag. Defined in proto.h.
441 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
442 given for unix local socket.
443 The COMSTACK string for doing so is:
446 unix:/myfile:tcp:localhost:9999/mybase
447 unix:/myfile:localhost:9999/mybase
448 unix:/myfile:http://fakehost/mybase
450 debian: Use dpkg-buildflags in build process.
452 --- 4.2.43 2012/10/19
454 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
455 global's SRU service uses a recordPosition scheme starting from zero.
456 First record's position should be one
457 according to the standard.
459 --- 4.2.42 2012/10/18
461 Allow more namespaces for SRU. This is to allow, for example, an
462 incorrect namespace returned from server
463 http://services.igi-global.com/sru .
465 Minor fixes for compilation on Windows.
467 --- 4.2.41 2012/10/11
469 daemon: log total number of bad signals from child on stop so that it
470 is more easy to spot problems with child worker processes.
472 retrieval: empty backend name attribute omits element set
473 from being used in retrieval.
475 --- 4.2.40 2012/10/04
477 Implement Solr sort strategy "solr", similar to sru11 sorting.
478 This will implement the correct parameters on Solr requst to do
481 --- 4.2.39 2012/09/28
483 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
486 MARC: Extra/missing indicator handled for MARCXML.
487 The indicator length is given in header and is the same for the
488 whole record. If attributes ind1, ind2 are missing, then content
489 character defaults to blank. Extra indicator attributes (beyond)
490 indicator length are treated as an error.
492 Reformat: delete trailing whitespace
494 --- 4.2.38 2012/09/17
496 MARC: fix non-ASCII characters for leader. This is to ensure we can
497 generate XML in UTF-8.
499 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
500 in one node with structure word.
502 --- 4.2.37 2012/09/04
504 yaz-json-parse: JSON output may be pretty printed by using option
507 Increase default value of max message for Z39.50 Init for GFS, ZOOM
508 and yaz-client. Old value was 1 MB. New value is 64 MB.
510 --- 4.2.36 2012/08/22
512 yaz-client: don't display bogus records from SRU servers. Some SRU servers
513 return more records than given by *maximumRecords*. Skipping those in
516 record_render: simplify buffer return handling and fix at least one bad
517 memory reference, that broke the test_embed_record sometimes.
519 Allow http://user:pass@host notation for yaz_url_exec.
521 zoomsh: allow shell command to be executed. Via the system(3) call.
523 yaz_poll: Allow num_fds == 0
525 yaz-client: fix bad encoding of "itemorder item". The itemorder
526 item <no> - command forgot to use length of encoded Item Request
527 package. Error present since YAZ 3.
529 yaz-ztest: fix bad usage of session handle. Bug was introduced when
530 result sets were saved (271a9c83).
532 SRU recordPacking: guess record packing in response rather than looking
533 at the recordPacking element which, OF COURSE, changed semantics in SRU
536 Decode SRU 2.0 responses. The official namespace for responses, according
537 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
538 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
539 nature.com's server, however, usee namespace
540 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
541 we are now using a glob-expr to match up the namespace. ZOOM C and
542 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
543 I can not find a single real example showing the "real" namespace in
544 the documentation from OASIS. The namespace for requests is different
545 from responses, but this is not added to YAZ yet, when we don't encode
548 --- 4.2.35 2012/06/26
550 zoom/record_render: add support for Base64 decoding fo MARC records
551 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
552 which will decode base64 + ISO2709 marc-8 encoded material from text node
555 --- 4.2.34 2012/06/07
557 Add missing definitions ZOOM_resultset_get_facet_field_by_index
558 and ZOOM_resultset_facets_names.
560 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
563 Change APDU dump printing to avoid long leading blanks. For levels 16
564 or larger the level is shown and the indentation is truncated but
565 recursed with modula 8. This makes it still reasonable easy to read
566 - even for nested BER dumps.
568 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
569 return 0 (incomplete package) in case where the BER package was
570 considered too nested (return value of -2).
572 dumpber: lines of level 15 are not indented further. Two spaces per
573 indentation; indentation 15 or more is indented to a fixed indentation
574 and augmented with a level=<no> indication.
576 zoomsh: increase max size of command+args
578 GFS: No limit in RPN buf size in CQL to RPN conversion.
580 --- 4.2.33 2012/05/09
582 New function for daemon utility, yaz_daemon_stop .
584 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
586 --- 4.2.32 2012/04/25
588 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
589 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
591 --- 4.2.31 2012/04/23
593 YAZ daemon utility relays SIGUSR1 to child process.
595 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
596 would result in en empty database list - which in turn would result in
597 encoding failure for search.
599 Fix reading beyond string in yaz_sort_spec.
601 --- 4.2.30 2012/04/11
603 Add two new SRU diagnostics:
604 236: Access to specified database denied
605 1015: Init/AC: Maximum number of simultaneous sessions for Userid
607 Document the very useful ZOOM-C option "apdulog".
609 CQL to RPN: term may be passed through verbatim. This is enabled with
610 truncation.cql . The assumption being that the term is already CQL.
612 --- 4.2.29 2012/03/20
614 record_conv: leader spec may be given for marc element.
615 The leader spec is given as attribute leaderspec for element marc.
616 For example to convert a MARC21 record from MARC-8 to UTF-8:
617 <marc inputformat="marc" outputformat="marc"
618 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
620 record_conv: allow user-XSLT params. For example:
621 <xslt stylesheet="MARC21slim2DC.xsl">
622 <param name="myparameter" value="myvalue"/>
623 <param name="otherparameter" value="othervalue"/>
626 record_conv: fix error handling for missing marc charsets.
628 CQL: fix extra terms in wrong order.
630 --- 4.2.28 2012/03/06
632 record_conv: modify new API for conversion types. The conversion types
633 may be passed in new functions yaz_record_conv_configure_t and
634 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
636 Avoid mixed statement/variable declare; fixes compilation with Visual
639 --- 4.2.27 2012/02/28
641 Add non-standard SRU diagnostic: 235: "Database does not exist".
642 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
643 Update SRU to Bib-1 diagnostic maps accordingly.
645 CCL: add two new diagnostics for unsupported masking. The new
646 diagnostics are: "Embedded truncation not supported" and
647 "Single charcacter mask not supported".
649 --- 4.2.26 2012/02/23
651 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
653 --- 4.2.25 2012/01/11
655 Build YAZ for Ubuntu Oneiric.
657 CCL: allow parantheses for proximity operands. For example CCL query
658 (a) % (b) is now allowed.
660 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
661 marked dead, rather then being destroyed. If not, the session memory is
662 being free'd before the search/scan handler is finished. Also destroy
663 'request' memory in request_release rather than in various places,
664 which resulted in leaks from time to time.
666 --- 4.2.24 2011/12/21
668 cql_sortby_to_sortkeys: honor sort prefix.
670 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
671 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
672 The rpn2cql family of functions now always returns quoted CQL terms.
674 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
676 --- 4.2.23 2011/12/15
678 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
679 sequence is treated as one. For example, &&a=b&&&c& is identical to
682 --- 4.2.22 2011/12/05
684 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
685 APDUs for a connection to a WRBUF.
687 --- 4.2.21 2011/11/23
689 Fix cql_sortby_to_sortkeys. Completely broken before.
691 Make CCL's @truncation work again.
693 --- 4.2.20 2011/11/09
695 New ZOOM connection setting: tproxy. It's like proxy, but does not
696 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
697 to set resolved address + port for a connection outside ZOOM itself.
699 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
701 --- 4.2.19 2011/11/07
703 Fix uninitialized variable in Solr spell support (could cause SEGV
704 for SRU response decoding).
706 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
707 back-end's addinfo through into the ZOOM response addinfo.
709 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
710 they are separated by a colon and a space rather than simply
713 --- 4.2.18 2011/10/28
715 Add support for Solr spell-checking/suggestions through ZOOM.
716 If a Solr target has been configured correctly for spelling-checking
717 and suggestions, these will now be returned on the ResultSet option
718 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
720 --- 4.2.17 2011/09/28
722 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
723 with a flag whether to substitute escape sequences or not.
725 --- 4.2.16 2011/09/22
727 Fix nmem_strsplit_escape to substitute escape char properly.
729 New option for zoomsh -e , which makes it abort on first error and
730 return process exit code to indicate success/failure.
732 YAZ options utility supports special option -- which makes all it treat
733 all following arguments as non-options.
735 --- 4.2.15 2011/09/16
737 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
738 searched if absolute filename is given.
740 Fix conv_xslt() error-reporting when stylesheet is not found.
741 (The value of fullpath is meaningless in this situation.)
743 --- 4.2.14 2011/09/07
745 Fix problem in CQL sort node creation: un-initialized memory.
747 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
748 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
749 CQL sortby depending on whether Type-1 or CQL is actually sent to the
752 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
753 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
755 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
756 will make it possible to use both single-character mask (#) and wildcard (?)
757 in CCL . Throw diagnostic for left truncation because that is not supported
760 --- 4.2.13 2011/09/01
762 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
763 cases using escapes (\-sequences) and masking.
765 PQF parse fix: A trailing backslash followed by end-of-string (\0)
766 would result in a read one byte beyond string.
768 rpn2ccl may use Z39.50 masking for terms (t=z).
770 ICU check fix. Don't include library -lCrun on Solaris, unless present.
772 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
773 not --cppflags (which seeems like an error in icu-config).
775 --- 4.2.12 2011/08/27 RPM package only
777 cql2ccl: fix conversion of terms: operator characters were not
780 --- 4.2.11 2011/08/25 RPM package only
782 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
783 CCL parser will map both # and ? to their regular expression
784 quivalents (. and .*).
786 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
787 of reserved CQL characters.
789 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
790 is, so that they are passed through.
792 --- 4.2.10 2011/08/24
794 ZOOM SRU mode: more aggressive re-connect.
796 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
797 made available as a utility function, declared in <yaz/logrpn.h>
799 rpn2cql_structure() supports proximity nodes (except that the Type-1
800 proximity node's "exclusion" binary is ignored, as there is no way to
801 express that in CQL). Fixes bug #4564.
805 Fix SEGV that could occur if set command of zoomsh was given without
806 value (2nd argument).
808 Fix SEGV that could occur if unsupported transport was given for
809 COMSTACK - say https (when SSL was unavailable).
811 Build yaz-url on Windows too.
815 New utility to get web content. Header is url.h. A command line tool
816 yaz-url is part of the distribution and packages.
818 Fixes for SSL COMSTACK (when gnutls is in use).
820 New functions yaz_base64{encode,decode}. Header is base64.h.
824 ZOOM C includes HTTP response buffer as additional info if it fails
825 to decode the SRU response.
827 Make wrbuf_json_puts available.
831 zoom: throw diagnostic for invalid value for option "sru". Before a
832 bad SRU request was sent.
834 Adding new utility wrbuf_vp_puts.
836 Add cclxmlconfig.obj to win/makefile. It was missing completely.
840 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
841 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
842 redirect was used at the same time.
844 MARC line mode decoding: be less picky about length given - first
845 5 digits of header that is.
847 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
849 Changes to decoding of SRU records: a record with recordPacking=xml is
850 modified with a new root element <yaz_record> if the recordData contains
851 multiple children elements. This is to make the record XML parseable
854 RPN to Solr conversion: encode special characters.
856 Generic Frontend Server: fix uinitialized member, stepSize.
860 Fix a bug in SRU decoding of records.. The database records stored
861 had un-initialized memory, but it would only be seen with yaz_record_render
862 and type_spec="ext" .
864 Fix a bug in ccl_qual_dup introduced in 4.2.3.
868 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
872 Add new utilities to convert from CQL to CCL . These utilities have
873 prefix cql_to_ccl defined in cql.h.
875 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
876 lead to memory heap corruptions when ICU utilities were in use.
880 Make compilation work without Libxml2.
882 yaz-client: remove redundant blanks in display of searchResult-1 term
887 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
888 resulting CQL node (tree) in a new node CQL_NODE_SORT.
890 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
891 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
892 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
893 Note that the CQL sortby spec is only converted when the GFS is already
894 converting from CQL to RPN (cql2rpn element).
896 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
897 specify whether to collapse delimitors or not. The existing nmem_strsplit
898 do collapse (collapse parameter = 1).
900 Windows installer: For NSIS, set InstallDir depending on x86/x64.
902 Rename internal func yaz_use_attribute_create. While non-static, this
903 function is not declared in a public header.
907 Add -lCrun when linking with ICU on Solaris.
909 More quicks character set conversions for OPAC records.
913 fix problem with record_render: records were converted (character set
914 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
918 SRU: add methods for handling DADS SRU-proxy facets.
920 Separate OPAC record character set for ZOOM_record. yaz_record_render
921 allows a character set given as charset=from/opacfrom,to where 'from' is
922 the character set of a bibliographic record, 'opacfrom' is character set
923 of OPAC record and 'to' is the target character set.
927 yaz-client: show may XML format records. Command show followed by 'format'
928 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
931 src/stemmer.c: Avoid using unnamed union. It is not supported by some
934 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
937 Update yaz.spec to operate on both SLES11 / Centos 5.5.
939 RPM: Release includes 'indexdata' name. Use indexdata in release name so
940 this package can be distinguished from other vendors.
942 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
943 as determined by configure
945 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
947 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
948 returns no error and no record, the present request is considered
949 partial (only a subset of the records could be returned by backend), and
950 so it is appropriate to set Present Status to partial-4.
954 Move yaz-config man pages to section 1.
956 More documentation about Solr.
958 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
959 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
960 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
961 peers on some Linux systems. However, in general that does not work
962 so YAZ can not rely on that to work. Debian changed behavior in this
963 respect from Debian lenny to Debian squeeze (still testing as of Oct
965 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
967 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
971 Fix yaz-config output: echo_source not set correctly by configure.
975 Solr Web Service support for yaz-client and ZOOM.
977 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
979 --- 4.0.12 2010/08/17
981 Z39.50 facet support. Facet specifications are passed for search in
982 other-information with ASN.1 as defined in facet.asn and OID
983 .10.1000.81.5 . Facets are expressed as an Attribute list as known
984 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
985 3 is limit (number of entries to get in response). yaz-ztest returns
986 dummy facets if a client asks for them.
988 --- 4.0.11 2010/07/09
990 CCL fixes: bug 2895 and bug 3539.
992 GR1-display: add comma in display - was removed by mistake in
995 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
997 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
999 --- 4.0.10 2010/06/18
1001 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1002 result set from a connection. The result set will be on its own
1003 thereafter; no operations on it will perform retrievals from a target.
1004 Only cached copies are returned.
1006 ZOOM C:fix case for HTTP servers responding with Connection:close.
1007 Ensure that if there is a current task it is resumed (like fetching
1008 more records in a result set) . Bug #3484.
1010 PQF parser: use odr_atoi for Odr_int (not atoi)
1012 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1013 values that contain any non-digits are treated as string attributes
1014 (previously decoding only checked for leading character ([0-9]). PQF
1015 encoding: attribute string values are not surrounded by double-quotes.
1017 --- 4.0.9 2010/05/21
1019 New utility for managing threads - thread_create.h.
1021 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1022 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1023 but YAZ' implementation do.
1025 Fixes for yaz_cond-functions on Windows 7.
1027 DLL export more symbols.
1029 zoomsh: show record do NOT render opac.
1031 Remove *.la files from Debian and RPM packages.
1033 --- 4.0.8 2010/05/11
1035 Debian package libyaz-dev depends on libgnutls-dev again (was
1036 removed in YAZ 4.0.6, but due to Libtool it is still needed
1037 even though yaz-config do not list libgnutls libs).
1039 ZOOM: Use only one WRBUF for returning string results for
1040 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1042 ZOOM: ZOOM_connection do not use a shared pointer to
1043 ZOOM_resultset after ZOOM_resultset is destructed by
1044 user. Reverts to YAZ 4.0.4 behavior.
1046 --- 4.0.7 2010/05/04
1048 record-conv: fix problem with at least one XSL conversion -
1049 due to probably incorrect usage of XML XSL documents.
1051 --- 4.0.6 2010/04/29
1053 Fix yaz-config for static mode and the use of SSL (gnutls).
1055 --- 4.0.5 2010/04/29
1057 Forward decl timeval struct in mutex.h and gettimeofday.h.
1059 yaz-config: fix 'static' mode linking.
1061 --- 4.0.4 2010/04/28
1063 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1064 are wrappers for pthreads or Windows. For Windows these are put in
1065 a separate DLL: yaz_cond4.
1067 libyaz.la (whole source) is compiled with thread. If thread support
1068 is enabled enabled, all source of YAZ is compiled with treading support.
1069 This allows core utilities such as yaz_log to use thread facilities.
1070 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1071 thread utilities. This commit moves mutex utilities (mutex.c) from
1072 libyaz_server.la to libyaz.la.
1074 yaz-json-parse displays leading text until error.
1076 --- 4.0.3 2010/04/09
1078 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1079 patch from Giannis Kosmas.
1081 SRU: no longer URL encode SRU database. The URL for an SRU server is
1082 a URL and such is alreeady encoded - at least when given with leading
1083 http:// or https://. This reverts behavior to YAZ 3.0.50.
1085 Support for new MARC XML notation TurboMARC which like MARCXML is a
1086 complete representation of MARC/ISO2709.. This one, however, is more
1087 compact and allows for faster processing with XSLT. TurboMARC can be
1088 used in the marcdisp.h API, from the yaz-marcdump utility and from
1091 yaz-ztest can be configured - via the database - to perform certain
1092 delays when it performs operations search, present and single record
1093 fetch. This allows testers to make yaz-ztest act as a real or even slow
1094 Z39.50 server. Refer to the yaz-ztest man pages for details.
1096 --- 4.0.2 2010/03/09
1098 wrbuf_destroy allows NULL WRBUF passed to it.
1100 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1102 Add ZOOM_connection_close.
1104 No fixed size buffers for ZOOM shell - bug #3257.
1106 tstodr: make it work on s390 platform.
1108 New icu iterator-functions. The new icu_iter-functions makes it possible
1109 to use ICU chains from many threads.
1111 yaz-client: better syntax check for show command.
1113 --- 4.0.1 2010/01/26
1115 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1118 New simple local-file XML include facility which allows file glob-patterns.
1119 Refer to yaz/xml_include.h.
1121 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1124 ZOOM_record_get supports new parameter "format" which makes it format XML
1127 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1128 JSONText in ECMA-262) is JSONValue, not JSONObject.
1130 --- 4.0.0 2010/01/20
1132 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1133 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1135 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1136 POSIX/Unix builds .so with major version 4.
1138 Remove old LOG_-defines from log.h. They have been obsolete and
1139 undefined by default for the last 5 years.
1141 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1143 GFS: Remove socket (int *fd) from search_rr handler. The socket
1144 descriptor ptr is a facility that allowed a search handler to supply
1145 a socket which would serve as a callback - when search was complete.
1146 This facility has now been in use for years.
1148 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1149 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1150 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1151 returns 'const char *' rather than 'char *. The returned string is
1152 read-only and should not be modified by applications. COMSTACK cs_close is
1153 now a void function - it no longer returns int. No applications check for
1154 the value and the implementations has always returned 0.
1156 ZOOM: use size_t for scan hit counts and str size. Functions
1157 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1158 occ (hit count) and len (string length) are now of type size_t pointer
1159 rather than int pointer. This is to be able to represent large hit counts
1160 and to also just to use the proper type for string length (strlen result).
1162 New JSON parser. Refer to include/yaz/json.h .
1164 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1165 Used to be int in some cases. Many wrbuf_-functions used to return an int
1166 indicating some length.. These return values were never used. And so they
1169 ODR: odr_malloc, odr_total now takes size_t for size.
1171 clone_z_type: fix leak; occurred for encoding failures.
1173 --- 3.0.52 2009/12/03
1175 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1176 bug was introduced in 3.0.51.
1178 --- 3.0.51 2009/12/02
1180 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1182 tcpip comstack: fix leak for getaddrinfo.
1184 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1185 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1186 Decoding of SRU "path" database is performed by private function
1187 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1188 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1190 yaz-client: honor base command for SRU. Change when database setting
1191 is applied for SRU and ensure it is kept when a connection is reset.
1192 Change also the way errors are displayed or SRU (decoding of packages).
1194 --- 3.0.50 2009/11/02
1196 Add support for extra request / response data for SRU codecs and GFS.
1197 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1198 for extra data response buffer and length. For the GFS, both request
1199 and response data (XML) is carried in extra_args and extra_response_data
1200 for the search handler. Patch by Ko van der Sloot.
1202 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1203 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1204 10010). This fixes bug #2113.
1206 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1207 cmdfile included a 'quit' command that would result in a memory violation.
1209 --- 3.0.49 2009/10/01
1211 Make a number of functions defined in xmlquery.c static. These have
1212 never been declared in a public header file (yaz/xmlquery.h) and was
1213 made public by mistake.
1215 Improve speed of character conversions (iconv utilities). This makes
1216 conversions from MARC-8 faster.
1218 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1219 unless type desired is "raw". This will prevent type "xml" from
1220 returning ISO2709 .. Which obviously can not be XML parsed.
1222 Fix memory leak in ZOOM that would occur if option apdulog was used
1223 on a re-used connection.
1225 Frontend server logs HTTP requests.
1227 Frontend server now sends Z39.50 close when it times out (sesssion has
1228 been idle for too long). Versions 2.0.30 and earlier also sent close.
1229 But due to a mistake this was disabled in all versions after that, i.e.
1230 the server would just close the socket immediately.
1232 yaz-client emits a better message when receiving an unrecognised
1233 userInformationField.
1235 Skip zero-length subfields when decoding ISO2709. This rare case happens
1236 if a record has two FS characters in a sequence. Without this patch
1237 there would be a reference beyond char array in using_code_len fragments
1240 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1242 --- 3.0.48 2009/08/28
1244 The show command offered by the zoomsh command now takes a 3d optional
1245 parameter type which is what is passed to ZOOM_record. If the type
1246 argument is omitted, "render" is used.
1248 RPN to CQL conv may use USE string attributes (bug #2978).
1250 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1252 --- 3.0.47 2009/07/08
1254 Function yaz_xml2query allows a diagnostic element in the PQF XML
1255 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1256 code and additional info respectively.
1258 The BER BOOLEAN is now the integral type Odr_bool which still happens
1259 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1260 typedef'd to Odr_int. This is still an integral 'int', but it may be
1261 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1262 ASN-1 compiler as well as programs has been updated to use the new types.
1264 --- 3.0.46 2009/06/08
1266 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1267 only the bibliographic record was rendered. For type=opac, an OPAC
1268 record is only returned if it is present.
1270 iconv: small fix for encoding of advancegreek.
1272 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1274 yaz-client: option auto_reconnect=on really reconnects.
1276 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1278 server: avoid null ptr ref for for yaz_poll errors.
1280 build: fix RPM build for RHEL 5.3.
1282 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1284 --- 3.0.45 2009/03/31
1286 Fixed bug #2709: TCP connect returns Invalid argument.
1288 Fixed compilation for mingw.
1290 Honor charset for raw records (ZOOM_record_get).
1292 Fixed use of errno for threaded mode that was seen on Solaris 10.
1294 Fixed argument passing with blanks in value for Windows Service.
1296 Disable YAZ' own log rotate by default (no 1 GB limit).
1297 The variable l_max_size which specifies the log file limit is set to 0
1298 (DISABLED): This is due to the fact that YAZ is most often deployed using
1299 logrotate. Also YAZ can not perform log rotate because of unsufficient
1300 permissions (setuid).
1302 --- 3.0.44 2009/02/17
1304 List supported encodings in man page for yaz-iconv.
1306 Fixed missing SSL libs for --libs output
1308 Re-established OID record syntax application-xml. Nobody should use it
1309 but we don't want to change soname because of this symbol being absent.
1311 --- 3.0.42 2009/02/02
1313 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1315 Added member named_result_sets for init handler struct for the GFS. This
1316 allows a server to disable named result sets.
1318 Removed OID record syntax application-xml.
1320 Added support for rule-based transliterator for ICU wrapper of YAZ.
1322 Fixed bug #1902: yaz-icu XML output.
1324 Make YAZ checks Emacs friendly.
1326 BITSTRING value shows value. Bug #2346.
1328 ISO2709 decoding: skip control characters from indicator data.
1330 Omit sort key by default in yaz-icu's output.
1332 Allow combined single char options (again) for YAZ' options function.
1334 Utility yaz-marcdump got option to display YAZ version (-V).
1336 Allow YAZ to use ICU 3.4.
1338 Added new ICU test case which illustrates removal of diacritics.
1340 --- 3.0.41 2008/12/29
1342 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1344 --- 3.0.40 2008/12/29
1346 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1349 Fixed bug #2352: yaz-marcdump crashes for certain record.
1351 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1353 Added support for Danmarc2 to UTF-8 conversion.
1355 Added support for ISO5426 to UTF-8 conversion.
1357 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1358 implementation version.
1360 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1362 --- 3.0.38 2008/11/10
1364 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1365 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1367 ZOOM C now interprets databaseName option for ZOOM connection as path
1370 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1372 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1374 Dummy Libxml2 types no longer defined in headers of YAZ'.
1376 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1379 --- 3.0.36 2008/09/26
1381 Various ODR chapter fixes.
1383 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1385 Added missing source for Windows compilation, mutex.c.
1387 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1389 For SRU connections in ZOOM all records up to "count" are now fetched.
1391 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1392 in Windows due to bad error handling for Libxml2.
1394 Added facility for sending arbitrary records (ASN.1 any) using
1395 ZOOM C's Extended service update. Patch by Sam Reynolds.
1397 New options for ZOOM C's connection, logapdu which makes ZOOM log
1400 --- 3.0.34 2008/06/18
1402 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1404 --- 3.0.32 2008/06/12
1406 Fixed memory violation that could occur when decoding UTF-8. This bug
1407 was only present in 3.0.30 of YAZ.
1409 --- 3.0.30 2008/06/06
1411 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1412 GNU TLS is used by default (if found).
1414 yaz-ztest returns OPAC records if a client asks for OPAC.
1416 Improved speed of MARC-8 encoding.
1418 Added support for lossy and loss-less MARC-8 encoding.
1420 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1422 Added new Windows Service wrapper (sc).
1424 yaz-client's itemorder command may now send a file.
1426 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1428 Added new function yaz_log_xml_errors.
1430 Allow (but warn) unknown XML attributes in MARCXML parsing.
1432 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1434 The UTF-8 to MARC-8 conversion now uses a different set of characters
1435 for Greek symbols. Bug #2120.
1437 --- 3.0.26 2008/02/21
1439 Added yaz_daemon (daemon.h).
1441 Fixed bug #2068: pkg-config trouble
1443 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1445 --- 3.0.24 2008/01/28
1447 Document --with-xml2 option.
1449 Added OPAC XML XSD (etc/opacxml.xsd).
1451 Allow glob mask for name attribute in retrieval element for the
1452 generic frontend server's retrieval facility.
1454 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1455 except POLLIN/POLLOUT.
1457 Fixed error handling in cs_listen. Bug #2037.
1459 --- 3.0.22 2008/01/20
1461 Fixed version in yaz/yaz-version.h.
1463 Fixed bug #2027: Crash when closing connection.
1465 Changed configure so that ICU support is only enabled if only ICU
1466 and Libxml2 is available (because the ICU chain is XML based).
1468 --- 3.0.20 2008/01/15
1470 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1471 is built. Only this DLL depends on the ICU runtime.
1473 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1474 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1476 Changed license of CCL module to 'Revised BSD'. After consultation with
1477 remaining members of the original EUROPAGATE consortium, we are re-issuing
1478 the CCL module without a separate license. The software was developed by
1479 Index Data as part of a research project. The special license was included
1480 to help feed usage information back to the project consortium to support
1481 project evaluation. At this time, the project consortium has long-since
1482 disbanded, and the majority of the original principals have retired. At the
1483 same time, we have significantly modified the software during the following
1484 years, to the point where very practically no original code remains. To
1485 simplify re-use of the software, we have contacted those members of the
1486 consortium who could be reached, and agreed to re-issue the module as a
1487 proper part of the YAZ package.
1489 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1491 CQL closer to being version 1.2 compliant. CQL also allows free-form
1492 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1495 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1496 bug could make Extended services handling crash in the ZOOM layer. This
1497 bug was only present in YAZ 3.0.18.
1499 --- 3.0.18 2007/12/19
1501 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1504 yaz-marcdump reads and writes collection wrapped records.
1506 Handle OPAC for record conversion module.
1508 Fixes for ICU wrapper.
1510 Allow ICU libs to be controlled with --with-icu .
1512 --- 3.0.16 2007/11/12
1514 Added yaz_poll which is a wrapper for select/poll. When poll is available
1515 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1516 sockets to be in use.
1518 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1519 functionality through an XML based configuration (ICU chain). This system
1520 is useful for search facilities such as Pazpar2 and Zebra that needs to
1521 perform tokenization of indexed material. The ICU code in a separate
1522 library libyaz3_icu.a.
1524 Added HTTP tunnel facility for COMSTACK, bug #1752.
1525 This is a facility that allows a Web proxy, such as squid, to tunnel
1526 Z39.50 traffic. This facility is "transparent" to must applications
1527 using YAZ. It's enabled by using pseudo transport connect: followed by
1528 the proxy address, followed by command, then follwed by he regular
1529 "virtual" addresss. For example,
1530 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1532 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1534 --- 3.0.14 2007/09/21
1536 Fixed bad memory reference in ZOOM_record - cuased by member not being
1537 initialized. This was a problem only in YAZ 3.0.12.
1539 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1540 fields were not removed.
1542 Changed the way C code is generated from codetables.xml. Made a MARC-8
1543 conversion trie for each characterSet section rather than codeTable.
1544 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1545 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1547 --- 3.0.12 2007/09/12
1549 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1550 from ZOOM_record_error).
1552 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1554 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1556 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1558 Better SRW-to-Bib-1 diagnostic mapping.
1560 ZOOM C and yaz-client announces SRU version 1.2 by default.
1562 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1565 Fixed in yaz_sru_decode to allow other version than 1.1.
1567 --- 3.0.10 2007/08/22
1569 Added support for SRU scan for ZOOM.
1571 Added support for the use of the older versions or Extended Service
1572 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1573 set to the version , 1=first, 2=second, 3=third. The third version is
1574 what ZOOM C has used so far. And that, obviously, is the default.
1576 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1577 therefore in Zebra and in SimpleServer-based applications). The new
1578 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1579 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1580 which is passed into the back-end search callback function.
1582 Added support for HTTP Basic authentication in clients: the SRU/W
1583 codec encodes the username/password elements of the PDU structure
1584 appropriately, and these may be set using the "user" and "password"
1585 options in ZOOM-C applications (the same options that are used for
1586 Z39.50 authentication).
1588 --- 3.0.8 2007/06/25
1590 Fixed bug #1208: SSL appears to be broken in ZOOM.
1592 Fixed bug #1206: Libxml2 include path weirdness.
1594 Added oid_name_to_dotstring.
1596 Allow elementSetName to be specified for ZOOM C record update.
1598 Allow waitAction to be specified for ZOOM C based for Extended Services.
1600 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1601 syntax OID. Bug introduced in YAZ 3 series.
1603 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1605 --- 3.0.6 2007/06/06
1607 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1608 directory. yaz-client now reads commands from file given by option -f
1609 if specified; then tries to read .yazclientrc in current directory.
1610 Failing that, it reads .yazclientrc from user's home directory.
1612 Added support for correlationInfo Note and ID for Record Update via
1615 Added yaz-client command querycharset which specifies character set for
1616 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1617 (termListAndStartPoint).
1619 Charset ISO5428:1984 is an alias for ISO5428-1984.
1621 Implemented a way to perform scan in a result set using Z39.50. This
1622 is achieved by attaching the result set name in the characterInfo
1623 (type InternationalString) of OtherInformation in the Scan Request PDU.
1624 The result set is identified in the otherinformation by the new OID:
1625 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1626 This allows for scan in result set and faceted search . Zebra did some
1627 of this in the APT term using attribute type 8 and value being result
1628 set. Using the OtherInformation approach for this is cleaner and easier
1629 to work with in proxies and the like. This facility can be used in
1630 yaz-client using new command setscan which takes a result set as first
1631 argument, start position (APT) as second.
1633 Changed decoding of SRU XML packed records to deal with servers that
1634 have recordData with XML data with multiple root nodes. Also make
1635 comparison for recordPacking case insensitive. Again, one server
1636 returns "XML" where others return "xml".
1638 For SRU responses allow Content-Type application/xml as well as text/xml.
1640 --- 3.0.4 2007/05/21
1642 Fixed bug in character set conversion of BER strings. Bug introduced
1645 --- 3.0.2 2007/05/08
1647 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1649 For OID class, use oid_class consistently.
1651 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1654 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1655 character set for bibliographic information interchange". By Giannis Kosmas.
1657 Added documentation on new OID API.
1659 --- 3.0.0 2007/05/02
1661 Changes to generic frontend server interface: added new member
1662 'query_charset' for bend_initrequest structure. A backend init handler
1663 should set this member to its native character set for query terms.
1664 When defined, the frontend server logic will announce this character set
1665 to a client if the negotiationModel bit is set by the client. All server
1666 implementors are encouraged to specify this. If a backend server does not
1667 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1669 Added CCL utility to remove terms (stop words) from resulting RPN
1670 tree. This is handled by functions with prefix ccl_stop_words_ .
1672 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1673 terms in RPN queries.
1675 Clean-up the CCL API. Moved some internal structures from ccl.h to
1676 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1677 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1678 This is replaced by ccl_parser_find_str which takes a string instead.
1680 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1681 libyaz.la is the core of YAZ except the generic frontend server and
1682 does not depend on POSIX threads anymore. libyaz_server.la is the
1683 generic frontend server facilities and uses POSIX thread functionality
1684 if available. The libyaz.la no longer depends on POSIX threads because
1685 the number of global structures is limited. NMEM no longer re-uses blocks
1686 between threads ; it simply free's memory immediately but allocates in
1687 "large" chunks as usual. We don't expect any performance penalties
1688 because of this. The yaz_log system is still using a global log_level so
1689 caution must be taken when modifying it with yaz_log_init_.. +
1690 yaz_log_mask_str. This, however, should not cause any trouble because
1691 these functions are called during initialization of application code
1692 anyway. `yaz-config --libs server` returns libs for server applications;
1693 `yaz-config --libs` returns libs for non-server applications.
1695 New OID database - with public definitions in oid_db.h. Removed old OID
1696 database including the head oid.h and definitions such as enum oid_value
1697 and struct oident. The new OID database uses the same string names as
1698 before but the 'protocol' is gone. There are now only two representations
1699 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1700 converts from string to OID; functions with prefix yaz_oid_to_string
1701 converts the other way.
1703 Change to emit_term() in CQL-to-PQF query translation: when a term has
1704 the /regexp relation modifier, do not process it for leading and
1705 trailing "^" and "*", which have quite different meanings in regular
1708 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1709 write handlers no longer carries a 'last' parameter. This will make
1710 yaz_iconv flush "less" characters. A flush is performed by call to
1711 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1713 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1714 removed, because function yaz_query_to_wrbuf does the same.
1716 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1717 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1719 Deprecated MARC utility functions removed.
1721 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1724 Branch split: YAZ_2_1_55_branch
1726 --- 2.1.54 2007/03/16
1728 Fix to ZOOM-C so that transparent reconnection is properly handled on
1729 connections that are in asynchronous mode.
1731 Fixed compilation on OpenBSD 4.0.
1733 Large strings in GRS-1 records are now properly displayed in yaz-client.
1735 Added character conversion support for "advancegreek"; based on patch from
1738 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1739 sequence is met. Before the error was not set so it would be unknown.
1741 Adjust yaz-marcdump MARC reader so that it skips until record separator
1744 --- 2.1.52 2007/03/07
1746 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1747 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1748 fd_set structure used as a bitmask for the FDs to be selected on.
1750 Using ACX_PTHREAD macro to check for POSIX threads.
1752 Fixed have-vsnprintf check.
1754 --- 2.1.50 2007/02/23
1756 Fixes for configure on BSD. Bug #900.
1758 Added snprintf/vsnprintf wrappers for systems that don't have
1759 limits (heavens forbid).
1761 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1762 created before all previous tasks were completed and removed from the
1763 task queue, the new task could be removed by a mistake.
1765 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1767 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1769 Fixed bug #832: Problem with MARC/charset in yaz-client.
1771 Fixed bug #668: save command line history for yaz-client.
1773 Fixed bug #830: pkg-config support.
1775 --- 2.1.48 2007/01/23
1777 Extended ZOOM result set options with two options that may be read by
1778 a client: resultSetStatus and presentStatus with values as specified for
1780 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1782 Fixed bug #827: Using SSL fails on Debian etch.
1784 Fixed bug #826: Weird looking chars for set of MARC records.
1786 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1787 that is treated as an ItemOrder with itemRequest being an XML document
1788 external. The value of "doc" is the content.
1790 Extended the GFS search facility. New member of bend_search_rr
1791 'estimated_hit_count' signals that hits is known to be an estmate
1792 (higher or lower than real hit count). New member 'partial_resultset'
1793 signals that the search was partial (hit count is lower or equal than
1794 real hit count). For Z39.50, the information is stored in resultSetStatus
1795 member of SearchResponse APDU. For SRU, the information is signalled
1796 via SRU diagnostic 59: "Result set created with valid partial results
1799 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1801 --- 2.1.46 2007/01/13
1803 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1805 Added ZOOM_connection_peek_event.
1807 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1808 the following new functions:
1809 ZOOM_event_nonblock, ZOOM_connection_process,
1810 ZOOM_connection_get_{socket,mask,timeout},
1811 ZOOM_connection_fire_event_{timeout,socket}.
1812 The existing blocking event handler, ZOOM_event, is a wrapper for the
1813 + blocking ZOOM_event_sys_{poll,select}.
1815 Implemented function ccl_xml_config which parses XML version of CCL
1816 configuration (bug #798).
1818 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1820 Added timings utility (yaz/timing.h)
1822 --- 2.1.44 2007/01/03
1824 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1827 Fixed bug #779: Rotation of apdu.log fails.
1829 Fixed for character set conversions:
1830 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1831 Honor G1 set in MARC-8 decoding.
1833 --- 2.1.42 2006/12/17
1835 Fixed bug #775: char conversion does not handle Alternative UTF-8
1838 Implemented function yaz_marc_read_line which parses MARC line format
1839 records. There is a wealth of formats out there. So far, this function
1840 reads line records produced by yaz_marc_write_line.
1842 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1843 more generic and easier to remember(!) options: -i format and -o format
1844 which specifies input format and output format respectively - where
1845 format is one of "marc", "marcxml", "line", "marcxchange".
1847 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1848 does not print anything except warnings for records.
1850 For yaz-marcdump, added support for MARC split into files (-s) with a given
1853 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1854 spec, at http://www.loc.gov/standards/sru/record-update/
1855 This has changed the binary layout of the following structs:
1856 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1857 bend_update_rr . Patch by Ko van der Sloot.
1859 Added GFS utility function bend_assoc_is_alive which returns 1 if
1860 association is still alive (client is connected); 0 otherwise (client
1861 closed connection). This allows busy servers to stop working for
1864 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1865 been a separate piece of software. This version of ziffy has been modified
1866 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1868 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1870 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1871 Client code may now interrogate options such as "init_opt_sort" to
1872 find out whether the server claims to support various options.
1874 --- 2.1.40 2006/11/27
1876 Added utilities yaz_{set,get}_esn to set/get element set name from
1879 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1880 of YAZ and has been so since YAZ 2.1.10.
1882 Implemented ZOOM_record_error which returns error information for
1883 record (surrogate diagnostic).
1885 --- 2.1.38 2006/10/31
1887 Updates for SRU Update by Ko van der Sloot:
1888 1. Changed name from "operation" to "action"
1889 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1890 versions in the code, marked as 'backward compatible'.
1891 3. Added diagnostics for SRU Update.
1893 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1895 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1897 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1899 For GFS, fixed problem with SRU diagnostic 'First record position out of
1900 range' being issued for 0 hits.
1902 zoomtst10 part of Windows Build.
1904 --- 2.1.36 2006/10/13
1906 Implemented yaz_filepath_comp which splits a path into file path
1907 components (required by Zebra 2.0.3+).
1909 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1910 BSD inspired license until now so this should not have any real impact on
1911 anybody. See http://www.opensource.org/licenses/bsd-license.php
1913 Fixed bug #687: Missing log lines.
1915 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1918 Fixed bug #689: SRU diagnostics to be added.
1920 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1921 whether a connection is idle (no more work do do).
1923 --- 2.1.34 2006/10/04
1925 Change type of optval from long to int for invocation of setsockopt with
1926 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1928 Added support for specifying the max log file size for the Generic
1929 Frontend Server. The size is given with option -r.
1931 --- 2.1.32 2006/09/21
1933 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1935 --- 2.1.30 2006/09/17
1937 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1940 Fixed bug in Generic Frontend Server that could cause a server to stop
1941 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1943 For the generic frontend server, the maximum record size is used as maximum
1944 size of incoming packages (SRU + Z39.50). The value until was previously
1945 only used in Z39.50 Init negotiation and, later, in a session controlled
1946 sizes of records returned. This is controlled using -k option. It can be
1947 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1949 --- 2.1.28 2006/09/04
1951 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1954 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1956 New option for yaz-marcdump -lpos=value which allows setting a portion
1957 of MARC header to a certain value.
1959 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1961 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1962 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1964 --- 2.1.26 2006/08/15
1966 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1969 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1971 --- 2.1.24 2006/08/08
1973 Fixed MARC ISO2709 encoding routines to deal with character set
1976 Minor changes to GFS logging. Database included in search request log
1979 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1980 cached/multiple records.
1982 Shared libraries are built by default on Unix+configure.
1984 Changed cql2pqf transformation to use a different evaluation order. The
1985 new order is: always, relation, structure, position, truncation, index
1986 and relationModifier. Old order was: always, relation, relationModifier,
1987 structure, index, position, truncation. Note that the the latter ones
1988 override former ones for identical attributes.. The new scheme means that
1989 it is possible to override any existing attribute with a relationModifier.
1990 And also that it is possible to override everything for the index rule
1991 (except the ones listed in relationModifier). No order is perfect but this
1992 one, we believe, covers more real cases.. The "always" should have been
1993 called "default", since the attributes there can be overridden with all
1996 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1997 compilation phase, but also for yaz-config --cflags output. This allows
1998 us to have public headers with Libxml2 stuff in them . It should also,
1999 eventually, make Libxml2 checks redundant in packages using YAZ, such
2002 --- 2.1.22 2006/06/15
2004 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2005 stored in uri, message and details.. Previously diagnostics were stored
2006 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2007 compatibility.. but he's probably the only one affected, so.
2009 Added support for CCL, compiled on the client side, in ZOOM-C. This
2010 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2011 input; the resulting query objects can be used for for searching with
2012 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2014 YAZ' configure searches for OpenSSL by default.
2016 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2017 SL_CTX_use_certificate_file. See
2018 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2019 for more info. Thanks to Ko van der Sloot.
2021 --- 2.1.20 2006/06/02
2023 Bug #600: SRU GET, POST support for yaz-client. Introduced
2024 command 'sru' which selects method SOAP/GET/POST.
2026 Allow missingValueAction to be specified for the sortspec string -
2027 function yaz_sort_spec. By default, the missing value action is null.
2028 Use ! to specify "abort". Use = followed by stringvalue to specify default
2031 Ensured that Present-handler (if defined) is called in GFS before any call to
2032 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2033 searchRetrieve requests.
2035 Documentation for YAZ is now based on the Docbook XML/XSLT using
2036 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2037 is no longer depending on jade/openjade or docbook-to-man scripts.
2038 PDF is no longer part of the distribution - but can optionally be
2039 made using DSSSL/jadetex or FOP.
2041 Added retrieval handling support in Generic Frontend Server to support
2042 conversion between MARC/XML as well as XSLTtransforms. See
2043 etc/yazgfs.xml for an example.
2045 Added Authentication support to Generic Frontend Server in SRU
2046 mode. Authentication using HTTP Basic is supported, as is the use
2047 of 'x-username' and 'x-password' parameters in the request itself.
2049 Added support for a new character set MARC8s identical to MARC8 except
2050 that it converts combined characters to single Unicode characters in the
2051 Latin-1 range (when possible).
2053 --- 2.1.18 2006/04/24
2055 ASN.1 compiler 0.4: generates brief Doxygen file header for
2056 generated .h/.c files.
2058 Utility yaz_iconv now supports conversion to MARC-8.
2060 New facilities for the MARC module. The reading - and writing of
2061 content are separate methods for the yaz_marc_t handle. The following
2062 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2063 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2064 format). Write functions have prefix yaz_marc_write_.. The existing
2065 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2066 available. Removed support for OAI-MARC and simplexml (not the
2067 simplexml from PHP5).
2069 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2070 to be returned for this connection.
2072 --- 2.1.16 2006/03/31
2074 Allow multiple languages and charsets to be specified with
2075 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2076 negcharset iso-8859-1,utf-8
2078 Translation of proximity nodes from CQL into PQF now works.
2080 Moved to automake 1.8, 1.9.
2082 Added function yaz_log_set_handler which allows a log handler to be
2083 installed. This handler will be called for all log messages. Output
2084 to file is also produced; but that can be disabled by passing NULL
2085 fname to yaz_log_init_file.
2087 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2089 For SRW (including GFS), accept application/soap+xml as content-type
2092 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2093 produces NO stylesheet reference even if a default stylesheet is specified
2096 --- 2.1.14 2006/03/14
2098 Updated Windows package to include yazd.dll + yazd.lib for the
2099 Development component.
2101 If the environment variable YAZ_LOG is set, then it is used as a
2102 string indicating the default level of logging to use if not
2103 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2104 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2105 used as before. So, for example, to omit warnings from YAZ logging,
2106 export YAZ_LOG=-warn
2108 cql_transform() now map structure and other attributes before indexes,
2109 so that index-specific structures and other attributes can override
2110 defaults. So now a combination of mapping specifications such as:
2112 index.dc.date = 1=date-modified 4=5
2113 does the right thing.
2115 cql_transform() now also respects the "always" mapping specification,
2116 which establishes an initial set of attributes to be used for all
2117 terms except where overridden by more specific attributes associated
2118 with the index, relation or modifier.
2120 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2121 which mode to use; one of "post", "get" or "soap" (SRW, default).
2123 Fixes for yaz_iconv routines: changed trie-based character set conversions
2124 to use only non-negative values for bit fields due to Sun's C compiler not
2125 supporting negative values.
2127 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2128 sequences where not read correctly. Fix by Rustam Usmanov.
2130 Updated win/makefile to use options, settings which makes things
2131 compile with VS C 2005.
2133 --- 2.1.12 2006/02/01
2135 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2137 In ZOOM socket code, use select instead of poll on MacOSX.
2139 ZOOM-C now support client-side compilation of CQL into RPN that is
2140 sent to the server, enabling CQL to be used against all Z39.50
2141 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2142 ZOOM_query object, and submit it using ZOOM_connection_search().
2143 The CQL-to-RPN translation uses a configuration file, the name of
2144 which must be specified in the Connection's "cqlfile" option.
2146 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2147 function, which takes as its start-term parameter a ZOOM_query object
2148 (which may have had either CQL or RPN set into it).
2151 --- 2.1.10 2005/11/29
2153 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2154 GFS to support this as well. Backend handler, bend_srw_update, does the
2155 update work. Code contributed by Ko van der Sloot.
2157 Allow retrieval of Search Result-1 information in ZOOM by the use of
2158 options that are attached to a result set. ZOOM documentation updated
2161 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2162 UTF-8 conversion. Patch by Raj Patel.
2164 Added option -m to GFS to control formatting of timestamps in log file.
2166 Added 'exit' as synonym for 'quit' in yaz-client
2168 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2169 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2170 for the new members. Patch by Ko van der Sloot.
2172 Added support for SRU POST. It is supported for content-type
2173 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2175 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2176 Instead make the library libyaz.la multi-threaded. Threading as a whole
2177 can still be disabled by configure option --disable-threads. Previosly,
2178 with older GLIBCs there were problems with MT libs under Apache. This
2179 has now been fixed a long time ago.
2181 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2184 CQL module modified to be case insensitive for relations/indexes/operations.
2186 Fixed bug in CQL transform code: incorrect value relationModifieder
2189 Added 'show all' command for yaz-client which retrieves all results
2192 Added new yaz-client, xmles, which takes a (private) OID and
2193 a document to be sent as an extended service request.
2195 Describe new yaz-client commands wait_response and set_auto_wait.
2197 Increase TCP/IP listener backlog from 3 (which I am guessing was
2198 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2199 that the socket will queue as many incoming connections as it's able
2200 to handle ongoing connections. In other words, it will never now
2201 refuse a connection that it would be able to handle merely because
2202 it's not got around to accepting() enough of the pending connections
2203 yet. This is the behaviour anyway under Linux, where the listen()
2204 argument is ignored; but not under BSD and on systems such as
2205 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2206 YAZ-based servers should now be uniform across operating systems in
2209 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2210 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2211 This allows yaz-marcdump to read large MARC batches (>2 GB).
2213 Modified all YAZ source files - except the source which is auto-generated
2214 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2217 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2218 corresponding to the existing *_setl() function. These allow option
2219 values containing arbitrary valuues.
2221 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2222 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2223 except that it returns an indicator of whether or not the sort
2224 criterion was accepted (0 for OK, -1 for invalid).
2226 --- 2.1.8 2005/06/07
2228 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2229 MARC output rather than returning "new" buffer.
2231 yaz-client warns about unknown init options.
2233 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2235 --- 2.1.6 2005/05/24
2237 Added support for SRW sort in Generic Frontend Server. Patch
2238 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2239 sortKeys - or NULL if none is provided.
2241 Fixed bug #307: It was impossible to specify indefinite/no timeout
2242 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2245 Added support for multiple languages and charsets to be specified in
2246 ZOOM. Each charset/language is separated by a blank. If negotiation is
2247 in effect in init-response, Option
2248 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2249 Code based on patch by Vasiliy Osadchuk.
2251 Fixed bug #306: infinite recursion that occurred when calling
2252 yaz_log_level_init as the first call (before other log level or
2255 Fixed bug in scan handling in front end server: if preferred-Position-In-
2256 Response was non-present, a NULL pointer referece was performed.
2258 --- 2.1.4 2005/04/26
2260 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2261 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2262 now defined for all those error codes. So instead of putting 109 in
2263 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2264 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2266 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2269 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2271 Program yaz-client now exits and produces an error message if multiple
2272 Z39.50 servers are specified on the command line (none or one allowed
2275 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2278 --- 2.1.2 2005/03/16
2280 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2282 Fixed bug #272: Preserve spacing for CCL terms.
2284 --- 2.1.0 2005/03/14
2286 Added support for virtual hosts and multiple backend servers for
2287 the YAZ frontend server. The configution is XML based and
2288 support specificition of CQL to RPN mappings and explain information.
2289 See section "Virtual Hosts" in the YAZ manual.
2291 Extended OPAC display utility. OPAC display utility renders
2292 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2293 to supplement yaz_marc_decode_wrbuf.
2295 Fixed a bug in MARC decoder that could caused it to crash for some
2296 invalid MARC records. More diagnostics and warnings where added in
2297 XML output (warnings, etc are stored in comments).
2299 --- 2.0.34 2005/02/08
2301 Fixes for UNIX domain sockets. Bug #261.
2303 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2305 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2306 Added yaz_marc_subfield_str which defines subfield lead string which is
2307 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2308 yaz_marc_endline_str which defines end of fields string used in
2309 YAZ_MARC_LINE format. Default string is newline.
2311 Experimental support for MarcXChange. This format can be produced
2312 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2313 http://www.bs.dk/standards/MarcXchange.xsd
2315 Added yaz-client commands scansize that sets maximum number of
2316 entries to be returned by scan.
2318 --- 2.0.32 2005/01/11
2320 Added support for SRW scan in yaz-client and Generic Frontend Server.
2322 * Added whereInList member to SRW Scan Term.
2324 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2326 Fixed NMEM system to return aligned blocks on the smallest boundaries
2327 that are suitably aligned for all possible types on the particular
2328 architecture YAZ is being built for.
2330 --- 2.0.30 2005/01/04
2332 Fixed numerious warnings that was issued with newer versions of GCC.
2334 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2335 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2338 Make YAZ Generic Frontend Server slightly faster.
2340 Enhance (and reduce) logging for Generic Frontend Server.
2342 Revert YAZ log system so that it flushes every write operation
2343 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2345 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2346 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2347 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2348 will effectively disable old definitions.
2350 --- 2.0.28 2004/11/09
2352 Added yaz_log_time_format which specifies log format using
2355 Added yaz_log_module_level which returns mask for a module. Value
2356 is non-zero mask a if module is enabled; zero if disabled.
2358 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2359 in include/yaz/cql.h.
2361 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2363 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2365 Fixed bug #172: RPM builds does not enable SSL.
2367 Doxyfile.in part of dist. Doxyfile generated by configure.
2369 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2370 are given and the corresponding component does not exist.
2372 Extend CCL documentation in YAZ reference. Describe r=r.
2374 --- 2.0.26 2004/10/01
2376 Fixed MARC->MARCXML conversion to properly deal with
2377 fields, subfields, indicators having non-ASCII characters.
2379 Fixed MARC->MARCXML conversion so that ASCII control characters
2380 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2383 Added YAZ GFS support for conversion from Z39.50 surrogate
2384 diagnostics to SRW surrogate diagnostics.
2386 Bug fix: YAZ GFS did not return schema in explainResponse.
2388 --- 2.0.25 2004/09/30
2390 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2391 now converts recordSchema to elementSetName as well as schema URI.
2393 Fixed bug in COMSTACK that prevented HTTP request packages from being
2396 --- 2.0.24 2004/09/29
2398 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2399 does not require white-space before and after the dash in a range, e.g.
2400 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2403 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2404 due to new GCC removing "redundant" code.
2406 Added yaz-client commands scanpos and scanstep that sets preferred
2407 position and step-size for scan.
2409 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2411 Added CCL utility ccl_qual_buf which parses one or more CCL
2412 spec lines in a buffer.
2414 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2415 of name and value - ignoring empty lines and comments.
2417 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2419 Added odr_get_element_path which returns current element path for an
2420 ODR handle. This utility is useful in error handling or user-defined
2423 Added ODR_PRINT utility odr_set_stream which is is a more generic
2424 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2425 to a write function and pointer to close function. The close function - if
2426 non-NULL - will be called during odr_destroy.
2428 Fixed bug in CCL parser where truncation char was not removed from
2429 right side when truncation=both was in effect.
2431 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2434 --- 2.0.23 2004/08/11
2436 Fix buffer overrun in CQL parser when dealing with proximity (%).
2438 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2439 to UTF-8/UCS conversion is now only based on codetables.xml.
2441 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2443 --- 2.0.22 2004/08/06
2445 Add support for more "commit changes" in ZOOM (uses Extended Services).
2447 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2450 Yet another small fix for configure of SSL.
2452 --- 2.0.21 2004/05/14
2454 Fix SSL libs for configure when --with-openssl=DIR is given.
2456 --- 2.0.20 2004/05/10
2458 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2460 SSL comstack now uses yaz.pem certificate file on server side
2461 by default. Certificate filename can be configured by calling
2462 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2464 Fix bug regarding multiple calls to ZOOM_connection_connect.
2466 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2468 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2469 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2471 ZOOM now allows inspection of X509 peer certificate for verification.
2472 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2474 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2475 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2476 as "modular" but it simplifies things.
2478 Added cs_get_peer_certificate to that returns peer X509 PEM.
2480 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2481 NULL if SSL is unavailable.
2483 Documentation about MARC decoding tools.
2485 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2487 --- 2.0.19 2004/03/30
2489 Rename CHANGELOG to NEWS to follow GNU style packing.
2491 Fix bug with missing initialization of member in init_diagnostics.
2492 This bug affects threaded version of GFS server.
2494 --- 2.0.18 2004/03/20
2496 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2499 Ensure zlib.dll is packed with Windows install.
2501 --- 2.0.17 2004/03/17
2503 Fix encoding of xsd:string to use text instead of CDATA.
2505 Fix endless loop in CQL parser with unbalanced ".
2507 Use a more compact way to store MARC-8 conversion tables.
2509 --- 2.0.16 2004/03/16 Debian only
2511 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2514 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2519 --- 2.0.15 2004/03/01
2521 Another fix for decoding of XML packed records.
2523 --- 2.0.14 2004/02/25
2525 Fixes for Chunked encoding. White space not ignored after length spec.
2527 Update NS and use default NS for SRW diagnostic elements.
2529 --- 2.0.13 2004/02/23
2531 Implement ZOOM_resultset_cache_reset which resets record cache.
2533 Implement ZOOM_resultset_sort which sorts a result set.
2535 Implement chunked HTTP transfer.
2537 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2539 --- 2.0.12 2004/02/16
2541 Added member 'schema' to bend_explain_rr structure so that backend
2542 can specify explain record identifier. Defaults to Zeerex 2.0.
2544 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2546 --- 2.0.11 2004/02/16
2548 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2551 Added init command for yaz-client which sends "extra" init request.
2553 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2554 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2556 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2558 Make ZOOM error code for "invalid query".
2560 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2562 --- 2.0.10 2004/02/05
2564 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2567 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2569 Added option -p <file> to make Generic Frontend Server to write PID file.
2571 Added option -D to put Generic Frontend Server in background on its own.
2573 Make ZOOM C recognize option "password". If unset, "pass" is used
2574 (for backwards compatibility).
2576 Fixed a bug in Generic Frontend Server that could make it crash if a
2577 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2580 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2581 Must be issued before open, in order to be in effect.
2583 --- 2.0.9-6 2004/01/12 Debian/Windows
2585 Make the SRU server more picky WRT unknown params, etc.
2587 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2589 New YAZ client command, options, that sets Z39.50 options.
2591 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2592 options from a string of tokens (one token for each option bit).
2594 Update SRW diagnostic code messages.
2596 --- 2.0.9-5 2004/01/07 Debian/Windows
2598 Handle user defined stylesheet for SRW/SRU.
2600 --- 2.0.9-4 2004/01/06 Debian/Windows
2602 Fix bug in decoding of Content-Length.
2604 --- 2.0.9-3 2004/01/06 Debian/Windows
2606 Fix a bug with decoding of XML packed records.
2608 --- 2.0.9-2 2004/01/05 Debian only
2610 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2612 Fix bug in SRW/SRU diagnostics decoding.
2614 --- 2.0.9 2004/01/05
2616 Fixed bug in Generic Frontend Server which could drop records exceeding
2617 preferred message size. Reported and fixed by Irina Dijour.
2619 Fixed calculation of package size for structured records in Generic
2620 Frontend Server. Reported and fixed by Irina Dijour.
2622 Fixed namespace for SRW/SRU diagnostics.
2624 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2626 --- 2.0.8 2003/12/22
2628 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2629 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2632 CQL changes to reflect recent changes to the specification:
2633 * Documentation talks about context sets instead of index sets.
2634 * Documentation talks about indexes instead of qualifiers.
2635 * The CQL-to-PQF transformer's configuration file now uses
2636 "index.set.name = <attributes>" instead of the old form
2637 "qualifier.set.name = <attributes>". (Both forms are still
2638 understood but the latter is deprecated.)
2639 * CQL terms with no explicit index specified are now interpreted as
2640 cql.serverChoice instead of srw.serverChoice (which of course
2641 behaves exactly the same.)
2643 --- 2.0.7 2003/12/16
2645 MARC conversion can now generate ISO2709 output in another
2646 character set. yaz-marcdump uses this facility if you invoke it
2649 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2650 functions from there can be used from C++.
2652 --- 2.0.6 2003/12/04
2654 Frontend server now transfers memory from decoded packages to stream
2657 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2658 references to show up.
2660 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2661 the ZOOM Abstract API. The older names for the same options are still
2662 also supported for the benefit of old applications.
2664 ZOOM-C supports "implementationId" and "implementationVersion" options
2665 to go along with "implementationName". These allow the user code to
2666 specify identification strings to be sent to servers.
2667 Add OID for the new ExtLite attribute set.
2669 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2670 as requested/supplid by Ere Maijala <ere@atp.fi>
2672 For generic frontend server, reverse the order of
2673 "toolkit-supplied / application-supplied" strings sent as implementationId,
2674 Name and Version. Also, remove the spaces around the slash. This brings
2675 the GFS in line with the behaviour of ZOOM-C on the client side.
2677 Add function ZOOM_scanset_display_term.
2679 yaz-client shows scan displayTerm if present.
2681 Utility yaz-iconv is now installed by default along with the man page
2684 Extend configure check for OpenSSL to use pkg-config where available (such
2687 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2688 server to specify uid/gid/mask for socket using the format
2689 unix:[user=uid,][group=gid,][umask=mask,]file=path
2690 If file= is omitted the existing format is assumed, e.g.
2692 in which case the mask is 0666 (rw for everybody).
2694 Major restructure of YAZ source. All source in libyaz is in src directory.
2695 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2696 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2698 Added man page for utility yaz-marcdump (used to be called marcdump).
2699 yaz-marcdump is installed by 'make install'.
2701 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2702 of incoming package failed.
2704 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2706 Change prototype of odr_perror: add const to message string.
2708 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2710 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2711 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2712 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2713 DNS lookup. There should not be any compatibility problems with this
2714 assuming that blocking=1 or 0 is used.
2716 Fix bad reference in UNIX comstack in function cs_addrstr.
2718 Fix for compilation on AIX.
2720 The generic front-end server (server/seshigh.c) now supports returning
2721 Init diagnostics to the client in User-information-field, in
2722 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2725 --- 2.0.4 2003/09/04
2727 Allow any CQL relation (not just all,any,exact,scr).
2729 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2730 that features the same UI.
2732 Implemented command update0 in YAZ client which is equivalent to
2733 update but uses old of Ext Update ASN.1.
2735 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2736 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2737 Previously no OID was used for this info.
2739 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2740 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2741 returns 'malformed search term' otherwise.
2743 SortResponse member resultCount now set to NULL in sort handler of
2746 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2749 Add three new utility functions for translating OIDs between various
2750 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2751 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2752 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2753 char *oid_to_dotstring(const int *oid, char *oidbuf);
2754 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2756 Reverted modifications for ES Update definition for z_IU0Update
2757 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2758 is back to YAZ 2.0.2.
2760 String value attributes for CCL parser.
2762 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2763 which their FirstSearch server returns in Init responses, sometimes
2764 carrying useful diagnostic information when Init fails. This has the
2765 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2766 "z39.50/oclcui.asn", where its definition is somewhat different from
2767 what OCLC document on their web-site, as required to interoperate with
2770 Support for anonymous authentication in yaz-client. Use the command
2773 * Fix the OID of the Index Data-local "admin" Extended Service from
2774 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2775 the 1000, which indicates a locally-defined OID, was a mistake.
2777 --- 2.0.3 2003/06/20
2779 Fix CCL directive @case handling so that it affects string match for
2780 both CCL keywords and qualifiers.
2782 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2783 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2784 Decoder has been updated with ASN.1 changes as listed in
2785 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2786 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2787 z_IUUpdate, remains unchanged.
2789 ZOOM_record_get may now return a record in a specific character set.
2790 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2791 "from" is the character set of record as returned by target. "to" is
2792 the character set to be returned. If omitted, "to" is UTF-8.
2794 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2796 New ODR utility, odr_getelement, which returns name of element for
2797 which encoding/decoding failed.
2799 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2800 in cases where a required element was omitted.
2802 Bug fix: some MARC8 sequences were not converted.
2804 New ZOOM option "step" which specifies number of records to be
2805 retrieved in one chunk. Used in conjunction with "start" and "count".
2807 SRW support for yaz-client. Use scheme http: to use it, e.g.
2810 yaz-client no longer does (un)intelligent character set conversions
2811 by default. Can be enabled with charset and marc_charset commands.
2813 xmalloc trace fix for 64-bit systems such as DEC alpha.
2815 Solaris 2.6 compile fix.
2817 New function, cql_strerror() translates SRW error codes, as returned
2818 by cql_transform_error(), into human-readable English strings. Used
2819 in yaz-client diagnostics when appropriate.
2821 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2822 converts it into a type-1 query which is sent to the server. This
2823 makes CQL available for use with all Z-servers, as opposed to the tiny
2824 minority that can handle CQL queries themselves.
2826 --- 2.0.2 2003/04/28
2828 New Debian package layout similar to the Redhat Package layout.
2830 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2831 and search result respectively.
2833 --- 2.0.1 2003/04/25
2835 Redhat package is now several packages: libyaz (runtime libraries),
2836 libyaz-devel (development and documentation, and yaz (utility programs).
2837 Package spec file by Morten Bogeskov.
2839 New member 'schema' in struct bend_fetch_rr which the name of requested
2840 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2841 handler MAY set this to reflect the schema of the returned record.
2843 New member 'display_term' in struct scan_entry. GFS now sets member entries
2844 and allocates scan entries to be filled by user scan handler. In previous
2845 version, entries member was allocated by the scan handler. That still works,
2846 but the GFS will ignore member display_term - assuming it was NOT set by
2847 the handler. The fact that the GFS now allocates the entries both allows
2848 for new members and makes a scan handler easier to write.
2850 Fix CQL lex buffer overflow.
2852 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2853 SRU default recordPacking is string.
2855 SRU protocol support for frontend server.
2857 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2859 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2861 Added scan for the ZOOM shell (zoomsh).
2865 * String Identifers for Schemas (Amendment 5).
2866 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2867 Old definition for schema
2868 Odr_oid *schema; /* OPT */
2873 Z_InternationalString *uri;
2874 #define Z_Schema_oid 1
2875 #define Z_Schema_uri 2
2878 * resultCount parameter to Sort Response (Amendment 1).
2879 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2881 Support for SRW 1.0 over HTTP. This is an optional feature and
2882 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2885 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2886 on the same port. SRW SearchRetrieveRequests are mapped
2887 to bend_init,bend_search,bend_fetch,bend_close.
2889 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2891 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2892 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2894 ZOOM connections are SRW based if schem http is used for hostname
2895 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2896 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2898 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2899 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2900 distance=n, order=true/false, relation=le, prox unit=word. If
2901 n is omitted, distance 1 is used.
2903 Fixed problem with C compiler include path in wrong order.
2905 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2906 on Solaris. Patch from Ko van der Sloot.
2908 New MARC decode API. All new functions operate on a yaz_marc_t
2909 handle. The most important new functions are: yaz_marc_create,
2910 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2911 decode and destroy respectively. Decoder can produce formats
2912 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2913 include/yaz/marcdisp.h.
2915 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2916 to UTF-8, UCS-32, wchar_t or Latin-1.
2918 * Prototypes for yaz_iconv_-functions moved to separate header
2919 include/yaz/yaz-iconv.h.
2921 Make a few private functions 'static' in unix.c. This prevents
2922 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2924 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2925 are set when Init Response is received.
2927 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2928 but returns diagnostic set as well.
2930 New function yaz_strerror which is a portable wrapper for
2931 strerror/strerror_r/GetLastMessage.
2933 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2934 is returned for MARC. If type is "oai", then OAI MARC is returned.
2936 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2939 --- 1.9.2 2002/11/26
2941 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2943 Fix bad race conditions on SIGTERM and terminate gracefully in
2946 Move retrieval (data1) module to Zebra since nobody seems to be
2949 Add GRS-1 render for ZOOM using same format as yaz-client.
2951 --- 1.9.1 2002/10/05
2953 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2955 Fix broken ESpec handling in data1 module.
2957 SGML reader parses comments and makes them part of the data1 tree.
2959 Added several type casts so that YAZ compiles as C++ code.
2961 ZOOM didn't handle PDU encoding failures properly.
2963 Added more Bib-1 diagnostics (approved extensions).
2965 GNU configure: better check for iconv.
2967 More portable use of accept, getpeername. Check for socklen_t. Use
2968 int/size_t if socklen_t is not defined.
2972 PQF parser rejects bad queries - including those with extra
2973 characters in them. PQF parser used to silently ignore that.
2974 Cleaner API for PQF added, which allows you to get detailed
2975 error information for bad queries (see yaz/pquery.h).
2977 Fixed bug in ZOOM_record_get for type "database".
2979 Implemented mini iconv library supporting conversions between
2980 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2982 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2984 --- 1.8.9 2002/08/20
2986 Fixed ZOOM C record cache so that preferredRecordSyntax and
2987 elementSetName is used to check for already fetched records.
2989 --- 1.8.8 2002/08/02
2991 Added three members in bend_initrequest structure to facilitate
2992 character set negotiation.
2994 Fixed a bug in frontend server that could cause indefinite
2995 loops under rare conditions.
2997 Revised character set utilities (charneg.h) so that encoding
2998 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3000 For PQF, directive @term <type> sets term type for Scan/Search.
3001 Here <type> is general, string, numeric, null. The term type
3002 is inherited - just like @attr.
3004 New call odr_set_charset that sets character set conversion for
3005 international-strings on a ODR stream. Prototype is:
3006 int odr_set_charset(ODR o, const char *to, const char *from);
3007 The InternationalString is still represented as C string in YAZ
3008 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3009 won't). On the protocol level, you can use any encoding.
3011 Support for UNIX sockets in ZOOM.
3013 Solaris recv sometimes returns errno == ENOENT. It is treated as
3014 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3016 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3017 both client and server. Code by Morten Bogeskov.
3019 --- 1.8.7 2002/05/22
3021 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3022 that they can be used directly from Visual Basic. You must recompile
3023 your windows APP if you're using ZOOM.
3025 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3026 Commands "lang" and "charset" sets language and character set respectively.
3027 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3028 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3030 Attributes from multiple CCL fields may be OR'ed rather than merged
3031 using directive "@field or". Fields are still merged by default -
3032 equivalent to "@field merge".
3034 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3037 Fixed bug in zget for parameter ExtendedServicesResponse.
3041 --- 1.8.6 2002/03/25
3043 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3045 Client displays USR.1:SearchResult-1 (hits per term).
3047 Additional Search Info for search in Generic Frontend Server.
3049 Fixed CCL parsing of "field=s".
3051 WIN32 installer - using the excellent NSIS software from nullsoft.
3053 Fixed CCL parsing of "field = - <number>".
3055 Added function yaz_marc_decode that decodes MARC for line mode
3056 display or XML (similar to that used by JZKit).
3058 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3059 Z39.50. But ISO/ILL was, however.
3061 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3062 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3067 --- 1.8.5 2002/02/03
3069 New YAZ client features: Command completion and new commands:
3070 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3071 Code provided by Jacob Poulsen.
3073 New call oid_trav, that visits all registered OIDs via callback.
3075 Function ZOOM_record_get now returns const char pointer rather than
3076 void pointer. It saves a lot of type casts.
3078 For YAZ client, command "auth" now allows you to set authentication
3079 in IdPass style. It is enabled when three tokens are given - order
3080 is user, group and password.
3082 Fix memory leaks in MARC record handling for ZOOM.
3084 New option for YAZ client, -k <kilobytes> that sets
3085 maximum record size. Similar to -k option for generic frontend
3086 server and yaz-ztest.
3088 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3090 Prefix query parser reports "fail" when bad attribute set is given.
3092 Fix in MARC decoder. Proximity logging. Fix for attribute set
3093 in scan handler for server. Patches by Shigeru Ishida.
3095 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3098 Configure option --with-openssl=<dir> now works when a directory is
3099 specified. Patch provided by Morten Bogeskov.
3101 New option for YAZ client, -u <auth>, that sets authentication.
3103 ZOOM fix: error information was sometimes "missing", since error
3104 was cleared/reset too when it shouldn't.
3106 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3108 --- 1.8.4 2002/01/04
3110 Scan for ZOOM API. New object ZOOM_scanset. New functions
3111 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3112 ZOOM_scanset_destroy.
3114 New ZOOM function, ZOOM_connection_last_event, that returns type
3115 of last event (such as "receive data", "send data", "apdu received",
3118 New ZOOM option, schema, that specifies schema for retrieval.
3120 New CCL feature. Qualifiers can be aliases for one or more
3121 other qualifiers (if more than one is given, OR is used).
3123 ZOOM uses named result sets if target supports it.
3125 Two new YAZ client commands: . (dot, which sources a script of YAZ
3126 client commands), and ! (to execute shell command.). Implemented
3129 Working on Debian packages.
3131 --- 1.8.3 2001/11/19
3133 YAZ client enables named result sets only if target supports it.
3135 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3137 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3138 with key="host" to get same result.
3140 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3141 Function Z3950_resultset_record(s) returns references to records
3142 "owned" by resultset. To become owner use Z3950_record_clone.
3144 Function z_ext_record handles Extended Services. Thanks to
3147 --- 1.8.2 2001/11/12
3149 CCL Parser fix: ignore token comma when dealing with and-lists.
3151 Documentation updates for COMSTACK.
3153 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3154 Changed prototype Z3950_records. For some functions, int parameters
3155 were changed to size_t.
3157 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3160 New MARC decode/display function, marc_display_exl, which properly rejects
3161 non-ISO2709 records. YAZ client uses it.
3163 --- 1.8.1 2001/10/29
3165 Fix bug: local attribute set wasn't set correctly in PQF strings.
3169 * Old Z39.50 codecs no longer supported.
3171 Added ZOOM C binding. See http://zoom.z3950.org/
3173 Renamed states for COMSTACKs to avoid confusion with events.
3175 Implemented cs_look and proper cs_rcvconnect.
3177 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3179 Configure detects POSIX threads on OpenBSD.
3181 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3182 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3184 When error is returned from present handler, non-surrogate diagnostic
3185 is returned in present response (and fetch handler is no longer called).
3187 * Minor adjustments to pquery parser (PQF). Token characters may be
3188 escaped by using backslash (C-style).
3190 PQF parser allows string attribute values to be specified. For @attr,
3191 non-numeric characters after the equal-sign are treated as strings
3192 (e.g. @attr 9=title).
3194 CCL trunction character may be defined (@truncation in file)
3196 * function zget_ExtendedServicesRequest sets waitAction to
3197 waitIfPossible (was wait).
3199 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3202 CCL operator names may be set in field definition files (CCL_bibset).
3203 See ccl/bib1 for an example.
3205 Fixes in ASN.1 compiler for C++ compatibility.
3207 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3208 and "op_or" to avoid conflict with C++.
3210 Fixed problem with GNU readline detection on Redhat 7.0.
3212 Added step-size for Scan backend handler.
3214 Fixed bug that made the frontend server crash when no attribute
3215 set was specified for scan.
3217 Front-end server automatically switches to original working directory
3218 when installed as an NT service. Previously -w had to be specified to
3221 Added extended attributes for retrieval module (data1), so that data1
3222 records carry d1_readXML/SGML attributes. d1_read also supports
3223 null-data rules ( <tag/>)
3225 On UNIX when POSIX threads are available, a separate library libyazthread
3226 is created. Programmers should link with that library and the yaz library
3227 when using threads. The reason for the split was that some applications
3228 on Linux, such as Apache, doesn't work well when using shared objects that
3231 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3232 (or any frontend server) in SSL mode by specifying ssl: followed by
3233 address. Only tested on UNIX.
3235 Added feature for CCL module. Virtual structure s=al or s=ol generates
3236 and-list and or-list respectively instead of phrase search.
3240 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3241 log_mask_str. This was done to avoid name conflicts with other libraries
3242 (such as other PHP extensions).
3244 Added raw OID member for preferred record syntax (request_format_raw)
3245 and returned record syntax (output_format_raw) for backend fetch method.
3247 Config file yaz-config now accepts options so that it returns specific
3248 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3250 Shared library support for UNIX using GNU libtool.
3252 * Modified backend interface. Request/Response struct's replaced by
3253 one read/write C struct. For example bend_fetchrequest and
3254 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3255 Every handler - even search has to be registered in bend_init
3256 handler. This means that the YAZ library no longer refers to
3257 external functions and it makes it possible to make the whole
3258 thing a single DLL/SO.
3260 Added Segment handler for backend server.
3262 Added Zmbol/Zebra administrative functions to YAZ client.
3264 Threaded frontend server on UNIX (when POSIX Threads are available).
3265 Starting the server with option -T enables multi-threading.
3269 Added configure option --enable-comp/disable-comp to control use
3270 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3271 located in sub directory asn.
3273 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3274 in ${exec_prefix}/bin along with the other programs yaz-client and
3277 GNU automake used to maintain makefiles.
3279 Added several OID's.
3281 Changed retrieval module so that we can load records with no abstract
3282 syntax defined. Tagpaths in these records are fully composed of string
3285 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3289 On UNIX, the generated makefile now supports a proper 'make install'.
3290 The prefix can be set via GNU configure to set the install location
3291 (default is /usr/local).
3293 * YAZ programs client and ztest were renamed to yaz-client and
3294 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3295 locations, such as /usr/bin,/usr/local/bin,etc.
3297 * YAZ Header files were moved from include to include/yaz. YAZ Header
3298 files are referred to as include <yaz/log.h> rather than <log.h>.
3299 The YAZ include path (-I ..) is therefore the same as before. Programmers
3300 should update their #include statements or use -Ipath/include/yaz
3301 instead. The main motivation for doing this change is that YAZ header files
3302 can be installed in "standard" locations /usr/include,/usr/local/include
3303 without introducing conflicts, since ALL YAZ header files are stored
3304 in subdirectory yaz (under /usr/include for example).
3306 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3307 rather than project/workspace files. We switched because project files
3308 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3311 Changed name of logging function, logf, to yaz_log, to prevent name
3312 clash with some math-log functions. The YAZ header log.h defines logf
3313 to yaz_log (#define) so there should be no incompatibilities by this
3316 Added bend_start/bend_stop handlers for server. These handler are
3317 called on start/stop of server. For windows they are called whenever
3318 a service is started/stopped.
3320 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3321 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3322 in util/yc.tcl. The auto-generated C code structures are, in a few
3323 cases, incompatible with the old decoders. There are differences in the
3324 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3325 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3326 The preprocessor variable ASN_COMPILED is defined when the compiled
3327 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3328 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3329 wish to use the old encoders/decoders you can specify --disable-yc
3332 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3333 version so that it supports both new - and old version of DB Update
3335 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3336 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3337 change. The name parameter can be set to 0 in which no name is specified
3338 for the construction. The macros odr_implicit and odr_explicit sets name
3339 parameter to zero for the construction involved. New macros
3340 odr_implicit_tag and odr_explicit_tag are similar to the others,
3341 except that a name parameter is added. For programmers' that don't use
3342 ODR they probably only need to change the call to z_APDU and z_External.
3344 Added access control facility by interfacing the TCP wrapper library.
3345 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3346 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3347 name of the daemon and enables the access control as specified in
3348 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3350 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3351 den Dool <H.M.vdnDool@kub.nl>.
3353 Added reference ID parameter to most functions in server API - refer
3354 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3356 Changed name of ccl library to libccl.a (was ccl.a).
3358 Fixed bug in decoder for Explain (Category TargetInfo).
3360 Added support for GNU readline in client. Thanks to Jacob Poulsen
3361 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3363 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3364 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3365 IMPLEMENTATION! This change was made to the development version before
3366 the ZIG decided to retract the amendment. If any users MUST be
3367 compatible with the original Update definition, PLEASE CONTACT US, and
3368 we will include a separate definition corresponding to the old Update
3369 ES. Note that because of the change to the ASN.1 of the
3370 TaskPackageRecordStructure we cannot define a single structure that
3371 will support both versions.
3373 * Added const modifier to buffer parameter for some ODR/BER encoding
3374 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3375 completeWAIS, odr_dumpBER.
3377 Fixed bug in client.c which caused a crash when a scanResponse didn't
3378 contain positionOfTerm.
3380 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3381 * will cause an error in a client if a non-YAZ target sends both a
3382 * list of Scan entries and non-surrogate diagnostics.
3384 Retrieval module enhancements. Tag sets may be typed in the reference
3385 to it. From the .abs-file the "tagset" directive takes a third optional
3386 integer type for the tag set referenced. From a .tag-file the "include"
3387 directive takes a third optional type as well. The old "type" directive
3388 in the tag set itself is still recognized but acts as the default type
3391 Backend interface change. Individual Scan terms returned from bend_scan
3392 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3393 in include/backend.h.
3395 Retrieval module enhancements. Multiple tag sets and attribute sets may
3396 be specified in abstract syntax specs. Revised the error/warning for
3397 logging messages reported by the retrieval module when reading the
3400 Object Identifier system (oid_..) changed. The API is backwards
3401 compatible but the oid-routines now allocates new OID's when needed.
3402 Raw OID's may be specified in oid_getvalbyname.
3404 YAZ now uses GNU configure to generate Makefile(s).
3406 * Minor changes in some of the member names of DeleteResultSetRequest and
3407 DeleteResultSetResponse. See include/proto.h.
3409 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3410 and added member 'languages' in TargetInfo (which was missing).
3412 Changed the way attribute sets are handled in the retrieval
3413 module. These are now cached, just like the abstract syntaxes
3416 Changed YAZ so that it links with compiled ASN.1.
3418 Added Explain-schema definitions and mapping routines. The following
3419 Explain categories have been implemented: AttributeDetails,
3420 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3422 Fixed minor bug in Windows version of Server Library.
3424 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3426 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3428 Added EXTERNAL: UNIverse Resource Report (non-standard).
3430 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3431 ENUMERATED and SET OF.
3433 * Added 'const' to some of the char pointer arguments for the
3434 functions, data1_read_node, data1_getelementbytagname,
3435 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3438 Fixed bug in data1_insert_taggeddata - the last_child member of
3439 parent wasn't initialised.
3441 * Changed data1_read_record and data1_read_node so that the supplied
3442 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3443 doesn't refer to any parts of the "SGML"-buffer.
3445 Fixed bug in server library (Windows version of statserv_remove).
3447 * Changed code so that it compiles as C++. The type definition
3448 of Odr_fun which is a member of Odr_arm was changed. The result is,
3449 that an explicit typecast is needed for the fun pointer when
3450 using Odr_arm - as in:
3451 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3453 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3455 Implemented the new structured date and time definition as approved
3456 by the ZIG. Added schemaId element to the specificTag in Espec-1
3457 (also approved at the last ZIG). Thanks to RVDM.
3459 Added some Object identifiers (RVDM).
3461 Changed the Update Extended Service (RVDM).
3463 Added command "refid" to client which specifies referenceId for
3464 the following requests.
3466 Implemented extended service handling for server. See ztest.c
3467 for an example as well as backend.h. New handlers are registerd
3468 in the Init handler.
3470 * Changed interface for sort in server.
3472 Added new members to statserv_options_block. It allows a server
3473 to read options from another source than just the command line. Thanks
3474 to Charles Woodfield.
3476 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3477 renamed to zboolean. Some C++ compilers complained about the name.
3479 Minor changes to gils.abs. Added index 's' (sort) on title
3480 and date/time-last-modified.
3482 --- 1.4pl2 1998/1/30
3484 Fixed bug in server library regarding inetd mode (-i). This bug
3485 was introduced by release 1.4.
3487 --- 1.4pl1 1998/1/29
3489 Added sort facility in client and backend server interface.
3491 Fixed problem with dependencies in Makefile(s).
3493 Fixed bugs for encoders/decoders of extended services and
3496 Implemented sub-tree feature for schemas. Sub-trees are
3497 referenced in *.abs-files. See explain.abs for an example
3498 of the use of this feature.
3500 Modified bib1.att; local attributes for ANY didn't include
3501 ANY itself (only affects use of the retrieval module).
3503 Fixed bug in plain SGML reader in function data1_read_node:
3504 tags with prefix "var" was incorrectly interpreted as variants.
3506 Added feature "sub-schemas" to enable references to - and definitions
3507 of - group of elements.
3509 * Removed member parent from type data1_element (in data1.h).
3511 Implemented function odr_nullval() that returns the value of
3514 * Removed member num_children from data1_node (in data1.h).
3516 Made NT service interface part of the server library. The
3517 function statserv_main uses the NT service when required and
3518 calls the statserv_start / statserv_close routines.
3520 Routine zget_SearchRequest and zget_PresentRequest fills
3521 resultSetName/Id member with "default" instead of "Default".
3523 Fixed memory leak in server. Request queue member wasn't freed.
3525 Fixed nmem_exit so that memory is freed.
3529 Revised the CCL parser utility to be thread safe.
3531 Added function, oid_ent_to_oid, to replace the function
3532 oid_getoidbyent, which is not thread safe.
3534 * Added nmem_init and nmem_exit to initialize and release
3535 NMEM resources. Function nmem_init should be called once in the
3536 initial thread before NMEM/ODR is used. statserv.c and client.c
3537 have been changed accordingly. The change was necessary to make
3538 NMEM thread safe. The NMEM memory pool is shared amongst threads
3539 in a process. Unix-based applications will still work fine without
3542 Added NT Services interface for the the Z39.50 (statserv) Server.
3543 Refer to the ztest.c source on the usage.
3545 Windows 95/NT port using MSVC5.0. Project files are included in the
3548 * Defined new 'global' handle for the retrieval (data1) system. The
3549 new handled, data1_handle, describes the state of the data1 system.
3550 This handle is passed as first argument to virtually all
3551 data1 related routines. The functions data1_create and data1_destroy
3552 creates and destroys a data1 handle respectively.
3554 Added ODR encode stream member to all backend request structures
3555 init, search, scan etc. This stream should be used to allocate all
3556 memory used for the response when thread safe operation is needed.
3558 Changed the comstack utility, cs_addstr, to be thread safe. The
3559 returned hostname string returned by the function is now part the
3562 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3563 function. The cs_straddr takes a COMSTACK handle as argument, so this
3564 function must be used after cs_create and before bind/connect.
3565 This function is thread safe.
3567 Moved test server to 'ztest' directory - generic server code still
3568 in 'server' directory.
3570 Made prefix query (pquery.c) utility thread safe.
3572 Added new function modifier YAZ_EXPORT to 'export' public DLL
3573 functions when using windows (see include/yconfig.h).
3575 Added definitions to the OID database (util/oid.c) (RVDM).
3577 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3579 Added call to ccl_rpn_delete in client program.
3581 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3582 release of RPN structure.
3584 Added support for C++, headers uses extern "C" for public definitions.
3585 With input from RVDM.
3587 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3588 Thanks to Ronald van der Meer (RVDM).
3590 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3592 Added support for private extensions to the OID database
3593 (oid_setprivateoids()). Thanks to RVDM.
3595 Added optional, physical ANY (key replication)
3597 Fixed null-reference problem in GRS-1 output filter.
3599 Proximity operator added to Prefix Query Format (PQF).
3601 In test client command "base" accepts multiple databases.
3603 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3607 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3609 Smallish bug-fixes in the new encoders/decoders (explain).
3611 Bug fixed in DeleteRequest.
3613 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3615 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3617 Added SOIF syntax (using private OID for now) to retrieval module and client.
3619 Added Update extended service.
3621 Added SearchResult-1 additional info structure.
3623 Added optional CCL (ISO8777) interpreter as separate module. Available
3626 --- 1.2 1996/6/10 (1st anniversary release)
3628 Added Summary record syntax. Lightly tested.
3630 Added OPAC record syntax. Untested.
3632 Added ResourceReport service encoders/decoders. Untested.
3634 Fixed bug in z_Unit - wrong tagging on unitSystem.
3636 Fixed bug in the DiagRecs decoder.
3638 Added options for max PDU size and session timeout to frontend-server.
3640 Added documentation of query-language parsers and other supporting utilities.
3642 [frontend-server] Added Attribute set to the bend_scanrequest API.
3644 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3645 surrogate diagnostics were generated.
3647 [retrieval] Allow multiple local values for attribute.
3649 [retrieval] Allow multiple attributes per element in .abs files. index type.
3651 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3653 --- 1.1pl2 1996/4/10
3655 Minor changes, mostly specific to Zebra's requirements (retrieval)
3659 Repaired bug in frontend server when running multiple listening
3660 endpoints in dynamic mode.
3662 z_External() now won't break if a known, ASN.1 value comes encapsulated
3663 in an octet-string. The value will pass through unmodified in an Odr_oct.
3665 Added a bit of code to the demo client to decode & display
3666 ASN.1-structured records represented in the octet-aligned branch of
3667 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3669 Added z_ext_getentbyref() to the ASN module. Doc updated.
3671 * Completed the SCAN definition in the ASN module. This may break SCAN
3672 code based on older YAZ-versions at compile-time. The fix is easy -
3675 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3676 under the SCAN definition. Remember to initialize this, server-people.
3678 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3679 that this does not extend to ODR and ASN.
3681 Comstack allows insertion of established socket (primarily for
3682 inetd-operation of servers). Doc updated.
3684 Front-end server can now start from the inetd in TCP mode. Doc
3687 --- 1.0pl4 1996/1/24
3691 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3692 the rank and record number.
3694 Adjustments to the frontend server.
3696 Fixed diagnostic BER dumper. It ignored the file argument.
3700 Various changes to retrieval module.
3702 Changed the union discriminators of the protocol files from enums to
3703 ints paired with #defines.
3705 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3708 *Changed operator in the RPN structure to 'roperator', again to avoid a
3711 Fixed problems in Explain decoders/encoders.
3713 --- 1.0pl2 1995/12/6
3715 Memory bug in log module fixed.
3717 --- 1.0pl1 1995/12/5
3719 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3721 Bug in Explain DatabaseInfo module fixed.
3723 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3727 The shift to v1.0 signals that we now consider the *core* functionality
3728 of YAZ reasonably stable (the core being more or less equivalent to
3729 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3730 tested (Explain not at all - though that will happen soonish).
3732 Minor changes to code to support Windows port.
3734 Various minor changes after we're getting to use GRS-1 & co. more.
3736 Added Espec-1 format.
3738 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3739 of the protocol and it cannot be selected when encoding (maps into 'string'
3740 when decoding). Needed to talk to some servers.
3742 Demo client can request simple element set names.
3744 Added Diagnostic Format encoders/decoders.
3746 Added simple Close handling to frontend server (no hooks for resource
3747 reporting yet), and demonstration client.
3749 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3751 --- 1.0b3 1995/08/24
3753 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3754 handled incorrectly when records were requested in the searchResponse. This
3755 will only affect you if you use the frontend-server.
3757 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3758 Test-client will ask for and print GRS1. Ztest will return dummy records
3761 Added Explain encoders/decoders to the service-level API. Untested.
3763 Added Extended Services: Item Order encoders and decoders to the Service-
3764 level API. Untested. We could use a recent copy of the pertinent bits
3765 of the ILL protocol to add those bits.
3767 Added diagnostic format 1 encoders/decoders to the service-level API.
3770 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3771 odr_cons.c, which causes a more correct output.
3773 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3774 was always set to 0 when no records were requested in the searchRequest.
3776 * Added better external-handling. This shouldn't harm old code that
3777 *encodes* externals. It can break code that looks for a
3778 'single-ASN1-type' representation, since those types that are known
3779 are now decoded immediately. Look at the SUTRS sample code in
3780 seshigh.c and client.c. Documentation updated.
3782 Handling of structured records in bend_fetchresponse. Length -1 marks
3783 structured record, type is deduced from format field.
3785 --- 1.0b2 1995/06/27
3786 Fairly quick maintenance release to add SUTRS support.
3788 Fixed handling of SUTRS records in the demonstration client.
3790 * Added format field to the bend_fetchrequest and bend_fetchresponce
3791 structures of the backend API (frontend server). When the record is
3792 returned, the value of the format field is mapped to an OID. The
3793 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3794 of the record. The special value VAL_NONE in the bend_request means
3795 that no specific format was requested by the client. Documentation
3796 updated accordingly. Test server (ztest) will return a fixed dummy
3797 SUTRS record if your client requests SUTRS.
3799 Documentation updated accordingly.
3801 You can now set external libraries and RANLIB support in the top-level
3805 First public release.
