3 Offer new utility function zget_AttributeList_use_string.
5 New conversion step, solrmarc, for record conversion module.
9 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
10 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
15 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
16 The standalone ZOOM sort was completely broken since 5.0.13.
18 ZOOM: generate event Connect rather than None for partial connect
19 (in fact getaddrinfo resolving).
21 ZOOM: only supply clientIP for InitRequest. Rather than for all
24 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
26 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
27 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
28 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
30 New "Facets" section in the documentation.
34 Call exsltRegisterAll in yaz_init_globals, so that all applications
35 using YAZ will have EXSLT things enabled.
37 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
39 Update various URLs to the re-organized SRU pages at LoC.
43 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
46 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
47 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
48 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
53 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
57 Fix gcrypt not properly initialized YAZ-740.
61 Describe memcached option for ZOOM.
63 ZOOM: throw present request out of range again YAZ-739
64 Was removed in YAZ 5.0.13.
68 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
69 with localtime_r when threads + fork is used (such as Metaproxy).
71 yaz-config: quote some RHS values (that might include blanks)
73 zoomsh: shows SearchResult-1
75 zoomsh: sortby command
77 zoomsh: use proper list of connections and result sets YAZ-725
79 Avoid yaz_log in sigterm handler for GFS YAZ-737
80 Logging is still performed, but outside sig handler.
82 New ZOOM C feature: result-set caching with memcached. Example:
83 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
85 Remove SSL via OpenSSL support YAZ-732
86 Also deprecate two functions from comstack that aren't working with
87 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
89 Revert "Bison: use %name-prefix directive rather than -p option"
93 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
95 SRU GET/Solr base URLs may hold additional ?args YAZ-729
96 ZOOM option extraArgs already does this, though. It seems useful
97 when dealing with Solr targets to limit by filter, eg.
98 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
100 Remove #fragment for HTTP request encoding YAZ-730
102 Doc: Update list of DLLs/LIBs
104 Doc: update href link to Unix utils and Git.
106 --- 5.0.11 2014/01/15
108 ZOOM: fix "lost connection" problem with servers that uses both squid
109 and another proxy behind it that returns Location headers with relative
112 zoomsh: do not use readline for stdin (no tty) YAZ-724
113 Just use fgets in that case. If the user hits Ctrl-D a new-line
116 zoomsh: empty command ignored YAZ-723
117 rather than performing exit of zoomsh.
119 yaz-url utility offers option -v to enable verbose mode.
121 yaz_url uses yaz_check_location and offers verbose mode.
123 Add new function yaz_check_location.
124 This function gets an absolute URI from Location (HTTP redirect).
126 cookie API: introduce yaz_cookies_reset
128 Update cql.y for newer bison YAZ-720
129 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
130 longer supported. Instead one must use %lex-param and %parse-param .
132 --- 5.0.10 2014/01/09
134 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
137 rpn2solr: support truncation left(2), left&right(3) YAZ-718
139 Mention SRU version 2.0 in yaz-client man page.
143 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
148 Make cs_parse_host public.A
150 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
151 introduced in YAZ 5.0.6.
155 Fix buffer corruption for yaz-ztest record fetch.
159 Allow yaz-ztest to return user-defined records (one record per file).
160 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
162 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
163 Use the stream write instead of odr_printf which has a 4K tmp buffer.
165 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
169 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
170 can read and write this format. For record format JSON, yaz-ztest returns
171 MARC-in-JSON records.
173 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
174 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
178 Improve error reporting for ICU chains YAZ-707
179 Report config element+rule when ICU status is "failure".
181 ZOOM: stop fetching if present response has no records YAZ-710
182 Some targets return less records than their hit count would suggest.
183 This prevents ZOOM from continuing to fetch records if any present
184 response has 0 records in the response.
186 Ensure that GFS calls exit if any listener fails YAZ-710
187 Before, if XML config was in use, it would start the default
192 yaz-ztest: -V shows version (like yaz-client -V)
194 New iconv encoding: danmarc YAZ-692
196 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
198 daemon: only wait for immediate child rather than all children. YAZ-704
200 yaz-client: fix setting of SRU record schema. If scheme was unset, it
201 could lead to invalid memory reference.
205 yaz-ztest returns schema for MARCXML test records. SRU require that
206 recordSchema for records.
208 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
209 instead of non-surrogate diagnostic. This is a per-record failure.
211 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
212 may refer to multiple listeners now. Attribute listenref is a comma separated
215 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
216 option is given for GFS, the dirname of filename (for -f) is used
217 as prefix for options such as cql2rpn, ccl2rpn, etc.
219 Content-Type charset fixes YAZ-701 . Do not inspect charset in
220 Content-Type header for SOAP when decoding SRU. The payload (XML)
221 itself tells what encoding it is. In response, never supply encoding
222 in Content-Type. The response payload (XML) tells what it is (with no
223 encoding in XML it's UTF-8).
225 HTTP decoding: allow blanks in URL paths YAZ-700
229 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
230 and facets. Ensure recordData and recordSchema are always present in
231 record element, because they are required.
233 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
236 Simplify in a lot of places using odr_strdupn.
238 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
242 Increase various buffers in GFS's statserv_options_block
243 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
244 This change makes many type-casts redundant, and, thus simplifies code.
246 Remove last bits of WAIS support.
248 Remove member 'size' from Odr_oct.
250 Slim down the public part of 'struct odr'. Most elements are not part
251 of struct Odr_private.
253 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
254 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
255 In particular facets are supported in both client - and server side.
256 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
257 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
258 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
259 both request/response). This is what a search handler in the GFS
260 will see (regardless of whether operating in SRU mode or Z39.50).
262 Changes to the srw.h (SRU/Solr) definitions include:
263 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
264 (char*), which replace union query and query_type (int). This is because
265 SRU 2.0 supports a queryType parameter. This also means that, to carry
266 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
267 x-pquery=PQFstring (extention parameter). The extension parameter
269 - New element, packing, that has information about SRU
270 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
272 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
274 New element, packing, in Z_SRW_explainRequest.
276 New elements in Z_SRW_scanRequest, queryType and scanClause.
277 These replace query_type and scanClase untion. This is similar to what
280 --- 4.2.69 2013/10/01
282 GFS: log when closing down - at least SIGTERM YAZ-684
283 Also change formatting WRT PID logging a bit.
285 Improve display of MARC records with multi-byte subfield IDs YAZ-695
286 In some rare cases subfield identifiers are multi-byte characters.
287 This will try to deterime length of those and split accordingly.
288 This affects display in line mode as MARCXML/MarcXchange. The encoding
289 of ISO2709 is the same.
291 Change inp argument to const for yaz_read_UTF8_char.
293 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
295 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
297 Better check of marc leader info YAZ-691
298 Problem is that some systems generate MARCXML/MarcXchange with
299 funny headers. These will not work if encoded as ISO2709.
300 Some tests produce new output, due to updated warning messages
302 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
304 yaz-client: display MAB records YAZ-689.
305 Thanks for Heiko Jansen for this patch.
307 New utility z_get_HTTP_Response_server which allows both HTTP server name
308 and HTTP server URL to be given in response.
310 Debian: do not depend on obs tcl8.3.
312 Debian: do not depend on obs libicu36-dev.
314 --- 4.2.68 2013/09/23
316 GFS: pass additionalSearchInfo to search memeber search_input if
317 given. Otherwise pass otherInfo. Request for facets and other search
318 related things will be passed there in future versions of YAZ.
320 New ZOOM setting, authenticationMode, which allows authentication
321 paramters to be encoded in the URL rather than via HTTP Basic auth.
324 rpn2solr: fix nested AND/OR handling. YAZ-685
326 Add comparison routines for some Z-types, such as NamePlusRecord,
327 RPNQuery, Query, RecordComposition and OtherInformation.
329 --- 4.2.67 2013/09/19
331 Don't decode MAB as MARC. Just like we don't attempt to decode
332 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
334 CCL: allow quoted terms for date ranges. YAZ-681
336 Introduce ccl_parser_qual_search. This function makes old function
337 ccl_qual_search, from YAZ 2, available again.
339 Add yaz_facet_list_to_wrbuf. YAZ-683
341 --- 4.2.66 2013/09/11
343 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
344 schema was given for search. YAZ-675
346 Add Solr date range searches. YAZ-621
348 --- 4.2.65 2013/08/22
350 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
352 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
354 ISO2709/MARC parse most octet aligned records; not just those that
355 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
356 MARC parse more records instead of just dumping as is. YAZ-670
358 ZOOM: proper caching for variations of record schema. YAZ-671
360 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
362 --- 4.2.63 2013/07/17
366 --- 4.2.62 2013/07/11
368 New utility z_get_HTTP_Response_details - an extended version of
371 New utility yaz_url_get_error which returns error message of last
372 failed yaz_url_exec call.
374 yaz-url and url functions: allow max HTTP redirects to be controlled.
376 New functions yaz_file_glob2, yaz_xml_include_glob.
377 These functions takes a flags parameter, which, for now only controls
378 whether to fail inclusion of a non-existing file (without glob
379 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
381 --- 4.2.61 2013/06/20
383 For MARC XML parsing, allow record without leader. A fake/default leader
384 is inserted and a warning is tagged with the record.
386 ICU: fix leak in in icu_iter_get_org_info.
388 --- 4.2.60 2013/06/14
390 ICU: fix bug in icu_iter_get_org_info (un-init variable).
392 --- 4.2.59 2013/06/11
394 Implement z_HTTP_header_remove.
396 --- 4.2.58 2013/06/11
398 ICU: Disallow 0 ptrs for some ICU string utilities.
400 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
401 returns original tokens (before normalization).
403 CCL: avoid z39.58/regex truncation when not needed. Apply only the
404 conversion of those masks, when absolutely necessary.
406 CCL: configurable masking character - @mask. Default masking character
409 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
410 full response anyway, so a Transfer-Encoding header will obstruct the
413 --- 4.2.57 2013/05/15
415 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
416 picking a socket. Problem is that some systems has IPV6 support, but
417 we can't create sockets for them, so we pick AF_UNSPEC first.
419 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
420 use content_len to determine resulting Content-Length in HTTP response
421 and NOT Content-Length supplied in headers by user.
423 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
424 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
426 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
429 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
430 with big endian and unsigned char (by default).
432 --- 4.2.56 2013/04/26
434 Fix yaz-client connect (crash in 4.2.55).
436 --- 4.2.55 2013/04/26
438 Fix proxy/host problem for ZOOM that could occur if unix sockets
441 New Debian package libyaz4-dbg.
443 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
444 differently in tcpip_close.
446 --- 4.2.54 2013/04/17
448 Windows installer of YAZ includes YAZ4J as a component.
450 CQL: allow "extra terms" again, by default. Thus, the CQL parser
451 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
452 and earlier. CQL parser may operate in strict mode where queries
453 not conforming to the standard BNF are rejected (syntax error).
454 Whether the CQL parser operates in strict mode is controlled with
455 cql_parser_strict . Strict mode enabled with option -S for utilities
456 cql2pqf and cql2xcql .
458 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
460 --- 4.2.53 2013/04/10
462 New charset, MARC-8c, which is like MARC-8 but allows control characters
463 0x01 through 0x1F, except ESC to be passed through verbatim.
465 Fix a problem with duplicate sub field character in MARC output. Problem
466 happened only when output was MARC-8 encoded.
468 --- 4.2.52 2013/04/03
470 yaz-ztest: Use hash for fake hit count. Before, random number was used.
471 This is problematic for unit tests using yaz-ztest. This patch also makes
472 a hash for CQL queries. For RPN, any term with a leading digit will be
473 treated as pseudu hit count (to force any particular hit count by a client).
475 yaz-ztest: return unique MARC dummy records. Beyond record offset
476 24, the author surname is patched with offset to make all records
479 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
480 on system wide default (/proc/sys/net/ipv6/bindv6only).
481 @4 binds to IPV4 only. @6 binds to IPV6 only.
483 Update CQL API documentation a bit
485 CQL: don't accept extra terms for queries. Makes the CQL parser
486 stricly conformant to the standard.
488 --- 4.2.51 2013/02/12
490 GFS: scan handler gets extra_args from request and may return extra
491 response data . That's for SRU only.
493 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
495 --- 4.2.50 2013/01/30
497 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
499 OPACXML: sync spelling of availabilityDate in XML to that of Schema
500 opaxxml.xsd. The schema had the correct spelling of this member always.
501 The ASN.1 was mis-spelled and still is (API change) - we are
502 not changing this. However, the OPAC to XML conversion had yet
505 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
508 New function, z_ext_record_oid_nmem, which is similar to
509 z_ext_record_oid but takes NMEM rather than ODR
511 --- 4.2.49 2013/01/18
513 ICU: New conversion element 'join' which joins tokens into one
514 with a custom character given by rule attribute.
516 --- 4.2.48 2013/01/10
518 New GFS search member: present_number. This is a hint to the
519 search handler how many records are going to be fetched immediately
520 following search. There's no guarantee that it's going to be the case,
521 since it depends on hit count (for Z39.50 piggyback) and whether errors
524 Make a few functions static (private). The functions getbyte_stream,
525 ungetbyte_stream and yaz_gets are now private. They were never declared
528 yaz-marcdump: exit(5) for serious decoding errors
530 ISO2709 decoding: be more picky WRT header
532 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
533 was only used as to indicate that next-result-set-position should be
535 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
536 Based on patch from Ashley Sanders.
538 Make some functions static/private in PQF parsing. Those functions were
539 never declared in a public header and so should not be in use by
540 applications based on YAZ.
542 --- 4.2.47 2012/11/23
544 ZOOM: special options to control APDU logging.
545 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
546 logging of APDUs until "saveAPDU" option is set again. If logging is
547 already enabled the effect is that current APDU buffer is cleared.
548 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
549 logging (default behavior on new connection).
550 The APDUs sent/received can be obtained by using
551 Using ZOOM_connection_option_get(c, "APDU") or
552 ZOOM_connection_option_getl(c, "APDU", &l).
554 GFS: relay implementation_version from backend
555 From 3.0.40 and later, implementation_version from backend was
556 not used in init response at all.
558 --- 4.2.46 2012/11/15
560 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
561 mode at all. Probably never did.
563 Make a new version of ztest.pem that, at least, is not expired.
565 --- 4.2.45 2012/11/13
567 Fix description of CCL directive 'case'.
569 More tight checking of form arguments (yaz_uri_to_array). Makes
570 YAZ better at rejecting big and/or bad POSTs.
572 SRU decoding does not report more than up to 10 invalid arguments.
574 rpn2cql: less quotes in generated terms. Semantics unchanged, but
575 it's prettier this way.
577 --- 4.2.44 2012/10/25
579 New utility yaz_decode_init_diag. Defined in proto.h.
581 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
582 given for unix local socket.
583 The COMSTACK string for doing so is:
586 unix:/myfile:tcp:localhost:9999/mybase
587 unix:/myfile:localhost:9999/mybase
588 unix:/myfile:http://fakehost/mybase
590 debian: Use dpkg-buildflags in build process.
592 --- 4.2.43 2012/10/19
594 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
595 global's SRU service uses a recordPosition scheme starting from zero.
596 First record's position should be one
597 according to the standard.
599 --- 4.2.42 2012/10/18
601 Allow more namespaces for SRU. This is to allow, for example, an
602 incorrect namespace returned from server
603 http://services.igi-global.com/sru .
605 Minor fixes for compilation on Windows.
607 --- 4.2.41 2012/10/11
609 daemon: log total number of bad signals from child on stop so that it
610 is more easy to spot problems with child worker processes.
612 retrieval: empty backend name attribute omits element set
613 from being used in retrieval.
615 --- 4.2.40 2012/10/04
617 Implement Solr sort strategy "solr", similar to sru11 sorting.
618 This will implement the correct parameters on Solr requst to do
621 --- 4.2.39 2012/09/28
623 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
626 MARC: Extra/missing indicator handled for MARCXML.
627 The indicator length is given in header and is the same for the
628 whole record. If attributes ind1, ind2 are missing, then content
629 character defaults to blank. Extra indicator attributes (beyond)
630 indicator length are treated as an error.
632 Reformat: delete trailing whitespace
634 --- 4.2.38 2012/09/17
636 MARC: fix non-ASCII characters for leader. This is to ensure we can
637 generate XML in UTF-8.
639 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
640 in one node with structure word.
642 --- 4.2.37 2012/09/04
644 yaz-json-parse: JSON output may be pretty printed by using option
647 Increase default value of max message for Z39.50 Init for GFS, ZOOM
648 and yaz-client. Old value was 1 MB. New value is 64 MB.
650 --- 4.2.36 2012/08/22
652 yaz-client: don't display bogus records from SRU servers. Some SRU servers
653 return more records than given by *maximumRecords*. Skipping those in
656 record_render: simplify buffer return handling and fix at least one bad
657 memory reference, that broke the test_embed_record sometimes.
659 Allow http://user:pass@host notation for yaz_url_exec.
661 zoomsh: allow shell command to be executed. Via the system(3) call.
663 yaz_poll: Allow num_fds == 0
665 yaz-client: fix bad encoding of "itemorder item". The itemorder
666 item <no> - command forgot to use length of encoded Item Request
667 package. Error present since YAZ 3.
669 yaz-ztest: fix bad usage of session handle. Bug was introduced when
670 result sets were saved (271a9c83).
672 SRU recordPacking: guess record packing in response rather than looking
673 at the recordPacking element which, OF COURSE, changed semantics in SRU
676 Decode SRU 2.0 responses. The official namespace for responses, according
677 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
678 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
679 nature.com's server, however, usee namespace
680 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
681 we are now using a glob-expr to match up the namespace. ZOOM C and
682 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
683 I can not find a single real example showing the "real" namespace in
684 the documentation from OASIS. The namespace for requests is different
685 from responses, but this is not added to YAZ yet, when we don't encode
688 --- 4.2.35 2012/06/26
690 zoom/record_render: add support for Base64 decoding fo MARC records
691 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
692 which will decode base64 + ISO2709 marc-8 encoded material from text node
695 --- 4.2.34 2012/06/07
697 Add missing definitions ZOOM_resultset_get_facet_field_by_index
698 and ZOOM_resultset_facets_names.
700 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
703 Change APDU dump printing to avoid long leading blanks. For levels 16
704 or larger the level is shown and the indentation is truncated but
705 recursed with modula 8. This makes it still reasonable easy to read
706 - even for nested BER dumps.
708 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
709 return 0 (incomplete package) in case where the BER package was
710 considered too nested (return value of -2).
712 dumpber: lines of level 15 are not indented further. Two spaces per
713 indentation; indentation 15 or more is indented to a fixed indentation
714 and augmented with a level=<no> indication.
716 zoomsh: increase max size of command+args
718 GFS: No limit in RPN buf size in CQL to RPN conversion.
720 --- 4.2.33 2012/05/09
722 New function for daemon utility, yaz_daemon_stop .
724 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
726 --- 4.2.32 2012/04/25
728 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
729 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
731 --- 4.2.31 2012/04/23
733 YAZ daemon utility relays SIGUSR1 to child process.
735 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
736 would result in en empty database list - which in turn would result in
737 encoding failure for search.
739 Fix reading beyond string in yaz_sort_spec.
741 --- 4.2.30 2012/04/11
743 Add two new SRU diagnostics:
744 236: Access to specified database denied
745 1015: Init/AC: Maximum number of simultaneous sessions for Userid
747 Document the very useful ZOOM-C option "apdulog".
749 CQL to RPN: term may be passed through verbatim. This is enabled with
750 truncation.cql . The assumption being that the term is already CQL.
752 --- 4.2.29 2012/03/20
754 record_conv: leader spec may be given for marc element.
755 The leader spec is given as attribute leaderspec for element marc.
756 For example to convert a MARC21 record from MARC-8 to UTF-8:
757 <marc inputformat="marc" outputformat="marc"
758 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
760 record_conv: allow user-XSLT params. For example:
761 <xslt stylesheet="MARC21slim2DC.xsl">
762 <param name="myparameter" value="myvalue"/>
763 <param name="otherparameter" value="othervalue"/>
766 record_conv: fix error handling for missing marc charsets.
768 CQL: fix extra terms in wrong order.
770 --- 4.2.28 2012/03/06
772 record_conv: modify new API for conversion types. The conversion types
773 may be passed in new functions yaz_record_conv_configure_t and
774 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
776 Avoid mixed statement/variable declare; fixes compilation with Visual
779 --- 4.2.27 2012/02/28
781 Add non-standard SRU diagnostic: 235: "Database does not exist".
782 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
783 Update SRU to Bib-1 diagnostic maps accordingly.
785 CCL: add two new diagnostics for unsupported masking. The new
786 diagnostics are: "Embedded truncation not supported" and
787 "Single charcacter mask not supported".
789 --- 4.2.26 2012/02/23
791 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
793 --- 4.2.25 2012/01/11
795 Build YAZ for Ubuntu Oneiric.
797 CCL: allow parantheses for proximity operands. For example CCL query
798 (a) % (b) is now allowed.
800 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
801 marked dead, rather then being destroyed. If not, the session memory is
802 being free'd before the search/scan handler is finished. Also destroy
803 'request' memory in request_release rather than in various places,
804 which resulted in leaks from time to time.
806 --- 4.2.24 2011/12/21
808 cql_sortby_to_sortkeys: honor sort prefix.
810 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
811 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
812 The rpn2cql family of functions now always returns quoted CQL terms.
814 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
816 --- 4.2.23 2011/12/15
818 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
819 sequence is treated as one. For example, &&a=b&&&c& is identical to
822 --- 4.2.22 2011/12/05
824 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
825 APDUs for a connection to a WRBUF.
827 --- 4.2.21 2011/11/23
829 Fix cql_sortby_to_sortkeys. Completely broken before.
831 Make CCL's @truncation work again.
833 --- 4.2.20 2011/11/09
835 New ZOOM connection setting: tproxy. It's like proxy, but does not
836 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
837 to set resolved address + port for a connection outside ZOOM itself.
839 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
841 --- 4.2.19 2011/11/07
843 Fix uninitialized variable in Solr spell support (could cause SEGV
844 for SRU response decoding).
846 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
847 back-end's addinfo through into the ZOOM response addinfo.
849 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
850 they are separated by a colon and a space rather than simply
853 --- 4.2.18 2011/10/28
855 Add support for Solr spell-checking/suggestions through ZOOM.
856 If a Solr target has been configured correctly for spelling-checking
857 and suggestions, these will now be returned on the ResultSet option
858 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
860 --- 4.2.17 2011/09/28
862 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
863 with a flag whether to substitute escape sequences or not.
865 --- 4.2.16 2011/09/22
867 Fix nmem_strsplit_escape to substitute escape char properly.
869 New option for zoomsh -e , which makes it abort on first error and
870 return process exit code to indicate success/failure.
872 YAZ options utility supports special option -- which makes all it treat
873 all following arguments as non-options.
875 --- 4.2.15 2011/09/16
877 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
878 searched if absolute filename is given.
880 Fix conv_xslt() error-reporting when stylesheet is not found.
881 (The value of fullpath is meaningless in this situation.)
883 --- 4.2.14 2011/09/07
885 Fix problem in CQL sort node creation: un-initialized memory.
887 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
888 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
889 CQL sortby depending on whether Type-1 or CQL is actually sent to the
892 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
893 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
895 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
896 will make it possible to use both single-character mask (#) and wildcard (?)
897 in CCL . Throw diagnostic for left truncation because that is not supported
900 --- 4.2.13 2011/09/01
902 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
903 cases using escapes (\-sequences) and masking.
905 PQF parse fix: A trailing backslash followed by end-of-string (\0)
906 would result in a read one byte beyond string.
908 rpn2ccl may use Z39.50 masking for terms (t=z).
910 ICU check fix. Don't include library -lCrun on Solaris, unless present.
912 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
913 not --cppflags (which seeems like an error in icu-config).
915 --- 4.2.12 2011/08/27 RPM package only
917 cql2ccl: fix conversion of terms: operator characters were not
920 --- 4.2.11 2011/08/25 RPM package only
922 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
923 CCL parser will map both # and ? to their regular expression
924 quivalents (. and .*).
926 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
927 of reserved CQL characters.
929 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
930 is, so that they are passed through.
932 --- 4.2.10 2011/08/24
934 ZOOM SRU mode: more aggressive re-connect.
936 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
937 made available as a utility function, declared in <yaz/logrpn.h>
939 rpn2cql_structure() supports proximity nodes (except that the Type-1
940 proximity node's "exclusion" binary is ignored, as there is no way to
941 express that in CQL). Fixes bug #4564.
945 Fix SEGV that could occur if set command of zoomsh was given without
946 value (2nd argument).
948 Fix SEGV that could occur if unsupported transport was given for
949 COMSTACK - say https (when SSL was unavailable).
951 Build yaz-url on Windows too.
955 New utility to get web content. Header is url.h. A command line tool
956 yaz-url is part of the distribution and packages.
958 Fixes for SSL COMSTACK (when gnutls is in use).
960 New functions yaz_base64{encode,decode}. Header is base64.h.
964 ZOOM C includes HTTP response buffer as additional info if it fails
965 to decode the SRU response.
967 Make wrbuf_json_puts available.
971 zoom: throw diagnostic for invalid value for option "sru". Before a
972 bad SRU request was sent.
974 Adding new utility wrbuf_vp_puts.
976 Add cclxmlconfig.obj to win/makefile. It was missing completely.
980 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
981 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
982 redirect was used at the same time.
984 MARC line mode decoding: be less picky about length given - first
985 5 digits of header that is.
987 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
989 Changes to decoding of SRU records: a record with recordPacking=xml is
990 modified with a new root element <yaz_record> if the recordData contains
991 multiple children elements. This is to make the record XML parseable
994 RPN to Solr conversion: encode special characters.
996 Generic Frontend Server: fix uinitialized member, stepSize.
1000 Fix a bug in SRU decoding of records.. The database records stored
1001 had un-initialized memory, but it would only be seen with yaz_record_render
1002 and type_spec="ext" .
1004 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1006 --- 4.2.3 2011/06/17
1008 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1010 --- 4.2.2 2011/06/10
1012 Add new utilities to convert from CQL to CCL . These utilities have
1013 prefix cql_to_ccl defined in cql.h.
1015 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1016 lead to memory heap corruptions when ICU utilities were in use.
1018 --- 4.2.1 2011/06/07
1020 Make compilation work without Libxml2.
1022 yaz-client: remove redundant blanks in display of searchResult-1 term
1025 --- 4.2.0 2011/05/18
1027 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1028 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1030 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1031 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1032 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1033 Note that the CQL sortby spec is only converted when the GFS is already
1034 converting from CQL to RPN (cql2rpn element).
1036 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1037 specify whether to collapse delimitors or not. The existing nmem_strsplit
1038 do collapse (collapse parameter = 1).
1040 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1042 Rename internal func yaz_use_attribute_create. While non-static, this
1043 function is not declared in a public header.
1045 --- 4.1.7 2011/03/15
1047 Add -lCrun when linking with ICU on Solaris.
1049 More quicks character set conversions for OPAC records.
1051 --- 4.1.6 2011/03/10
1053 fix problem with record_render: records were converted (character set
1054 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1056 --- 4.1.5 2011/03/08
1058 SRU: add methods for handling DADS SRU-proxy facets.
1060 Separate OPAC record character set for ZOOM_record. yaz_record_render
1061 allows a character set given as charset=from/opacfrom,to where 'from' is
1062 the character set of a bibliographic record, 'opacfrom' is character set
1063 of OPAC record and 'to' is the target character set.
1065 --- 4.1.4 2011/02/21
1067 yaz-client: show may XML format records. Command show followed by 'format'
1068 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1071 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1074 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1076 --- 4.1.3 2011/01/27
1077 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1079 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1080 this package can be distinguished from other vendors.
1082 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1083 as determined by configure
1085 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1087 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1088 returns no error and no record, the present request is considered
1089 partial (only a subset of the records could be returned by backend), and
1090 so it is appropriate to set Present Status to partial-4.
1092 --- 4.1.2 2010/11/02
1094 Move yaz-config man pages to section 1.
1096 More documentation about Solr.
1098 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1099 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1100 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1101 peers on some Linux systems. However, in general that does not work
1102 so YAZ can not rely on that to work. Debian changed behavior in this
1103 respect from Debian lenny to Debian squeeze (still testing as of Oct
1105 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1107 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1109 --- 4.1.1 2010/10/05
1111 Fix yaz-config output: echo_source not set correctly by configure.
1113 --- 4.1.0 2010/10/05
1115 Solr Web Service support for yaz-client and ZOOM.
1117 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1119 --- 4.0.12 2010/08/17
1121 Z39.50 facet support. Facet specifications are passed for search in
1122 other-information with ASN.1 as defined in facet.asn and OID
1123 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1124 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1125 3 is limit (number of entries to get in response). yaz-ztest returns
1126 dummy facets if a client asks for them.
1128 --- 4.0.11 2010/07/09
1130 CCL fixes: bug 2895 and bug 3539.
1132 GR1-display: add comma in display - was removed by mistake in
1135 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1137 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1139 --- 4.0.10 2010/06/18
1141 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1142 result set from a connection. The result set will be on its own
1143 thereafter; no operations on it will perform retrievals from a target.
1144 Only cached copies are returned.
1146 ZOOM C:fix case for HTTP servers responding with Connection:close.
1147 Ensure that if there is a current task it is resumed (like fetching
1148 more records in a result set) . Bug #3484.
1150 PQF parser: use odr_atoi for Odr_int (not atoi)
1152 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1153 values that contain any non-digits are treated as string attributes
1154 (previously decoding only checked for leading character ([0-9]). PQF
1155 encoding: attribute string values are not surrounded by double-quotes.
1157 --- 4.0.9 2010/05/21
1159 New utility for managing threads - thread_create.h.
1161 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1162 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1163 but YAZ' implementation do.
1165 Fixes for yaz_cond-functions on Windows 7.
1167 DLL export more symbols.
1169 zoomsh: show record do NOT render opac.
1171 Remove *.la files from Debian and RPM packages.
1173 --- 4.0.8 2010/05/11
1175 Debian package libyaz-dev depends on libgnutls-dev again (was
1176 removed in YAZ 4.0.6, but due to Libtool it is still needed
1177 even though yaz-config do not list libgnutls libs).
1179 ZOOM: Use only one WRBUF for returning string results for
1180 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1182 ZOOM: ZOOM_connection do not use a shared pointer to
1183 ZOOM_resultset after ZOOM_resultset is destructed by
1184 user. Reverts to YAZ 4.0.4 behavior.
1186 --- 4.0.7 2010/05/04
1188 record-conv: fix problem with at least one XSL conversion -
1189 due to probably incorrect usage of XML XSL documents.
1191 --- 4.0.6 2010/04/29
1193 Fix yaz-config for static mode and the use of SSL (gnutls).
1195 --- 4.0.5 2010/04/29
1197 Forward decl timeval struct in mutex.h and gettimeofday.h.
1199 yaz-config: fix 'static' mode linking.
1201 --- 4.0.4 2010/04/28
1203 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1204 are wrappers for pthreads or Windows. For Windows these are put in
1205 a separate DLL: yaz_cond4.
1207 libyaz.la (whole source) is compiled with thread. If thread support
1208 is enabled enabled, all source of YAZ is compiled with treading support.
1209 This allows core utilities such as yaz_log to use thread facilities.
1210 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1211 thread utilities. This commit moves mutex utilities (mutex.c) from
1212 libyaz_server.la to libyaz.la.
1214 yaz-json-parse displays leading text until error.
1216 --- 4.0.3 2010/04/09
1218 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1219 patch from Giannis Kosmas.
1221 SRU: no longer URL encode SRU database. The URL for an SRU server is
1222 a URL and such is alreeady encoded - at least when given with leading
1223 http:// or https://. This reverts behavior to YAZ 3.0.50.
1225 Support for new MARC XML notation TurboMARC which like MARCXML is a
1226 complete representation of MARC/ISO2709.. This one, however, is more
1227 compact and allows for faster processing with XSLT. TurboMARC can be
1228 used in the marcdisp.h API, from the yaz-marcdump utility and from
1231 yaz-ztest can be configured - via the database - to perform certain
1232 delays when it performs operations search, present and single record
1233 fetch. This allows testers to make yaz-ztest act as a real or even slow
1234 Z39.50 server. Refer to the yaz-ztest man pages for details.
1236 --- 4.0.2 2010/03/09
1238 wrbuf_destroy allows NULL WRBUF passed to it.
1240 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1242 Add ZOOM_connection_close.
1244 No fixed size buffers for ZOOM shell - bug #3257.
1246 tstodr: make it work on s390 platform.
1248 New icu iterator-functions. The new icu_iter-functions makes it possible
1249 to use ICU chains from many threads.
1251 yaz-client: better syntax check for show command.
1253 --- 4.0.1 2010/01/26
1255 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1258 New simple local-file XML include facility which allows file glob-patterns.
1259 Refer to yaz/xml_include.h.
1261 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1264 ZOOM_record_get supports new parameter "format" which makes it format XML
1267 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1268 JSONText in ECMA-262) is JSONValue, not JSONObject.
1270 --- 4.0.0 2010/01/20
1272 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1273 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1275 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1276 POSIX/Unix builds .so with major version 4.
1278 Remove old LOG_-defines from log.h. They have been obsolete and
1279 undefined by default for the last 5 years.
1281 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1283 GFS: Remove socket (int *fd) from search_rr handler. The socket
1284 descriptor ptr is a facility that allowed a search handler to supply
1285 a socket which would serve as a callback - when search was complete.
1286 This facility has now been in use for years.
1288 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1289 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1290 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1291 returns 'const char *' rather than 'char *. The returned string is
1292 read-only and should not be modified by applications. COMSTACK cs_close is
1293 now a void function - it no longer returns int. No applications check for
1294 the value and the implementations has always returned 0.
1296 ZOOM: use size_t for scan hit counts and str size. Functions
1297 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1298 occ (hit count) and len (string length) are now of type size_t pointer
1299 rather than int pointer. This is to be able to represent large hit counts
1300 and to also just to use the proper type for string length (strlen result).
1302 New JSON parser. Refer to include/yaz/json.h .
1304 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1305 Used to be int in some cases. Many wrbuf_-functions used to return an int
1306 indicating some length.. These return values were never used. And so they
1309 ODR: odr_malloc, odr_total now takes size_t for size.
1311 clone_z_type: fix leak; occurred for encoding failures.
1313 --- 3.0.52 2009/12/03
1315 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1316 bug was introduced in 3.0.51.
1318 --- 3.0.51 2009/12/02
1320 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1322 tcpip comstack: fix leak for getaddrinfo.
1324 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1325 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1326 Decoding of SRU "path" database is performed by private function
1327 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1328 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1330 yaz-client: honor base command for SRU. Change when database setting
1331 is applied for SRU and ensure it is kept when a connection is reset.
1332 Change also the way errors are displayed or SRU (decoding of packages).
1334 --- 3.0.50 2009/11/02
1336 Add support for extra request / response data for SRU codecs and GFS.
1337 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1338 for extra data response buffer and length. For the GFS, both request
1339 and response data (XML) is carried in extra_args and extra_response_data
1340 for the search handler. Patch by Ko van der Sloot.
1342 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1343 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1344 10010). This fixes bug #2113.
1346 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1347 cmdfile included a 'quit' command that would result in a memory violation.
1349 --- 3.0.49 2009/10/01
1351 Make a number of functions defined in xmlquery.c static. These have
1352 never been declared in a public header file (yaz/xmlquery.h) and was
1353 made public by mistake.
1355 Improve speed of character conversions (iconv utilities). This makes
1356 conversions from MARC-8 faster.
1358 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1359 unless type desired is "raw". This will prevent type "xml" from
1360 returning ISO2709 .. Which obviously can not be XML parsed.
1362 Fix memory leak in ZOOM that would occur if option apdulog was used
1363 on a re-used connection.
1365 Frontend server logs HTTP requests.
1367 Frontend server now sends Z39.50 close when it times out (sesssion has
1368 been idle for too long). Versions 2.0.30 and earlier also sent close.
1369 But due to a mistake this was disabled in all versions after that, i.e.
1370 the server would just close the socket immediately.
1372 yaz-client emits a better message when receiving an unrecognised
1373 userInformationField.
1375 Skip zero-length subfields when decoding ISO2709. This rare case happens
1376 if a record has two FS characters in a sequence. Without this patch
1377 there would be a reference beyond char array in using_code_len fragments
1380 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1382 --- 3.0.48 2009/08/28
1384 The show command offered by the zoomsh command now takes a 3d optional
1385 parameter type which is what is passed to ZOOM_record. If the type
1386 argument is omitted, "render" is used.
1388 RPN to CQL conv may use USE string attributes (bug #2978).
1390 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1392 --- 3.0.47 2009/07/08
1394 Function yaz_xml2query allows a diagnostic element in the PQF XML
1395 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1396 code and additional info respectively.
1398 The BER BOOLEAN is now the integral type Odr_bool which still happens
1399 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1400 typedef'd to Odr_int. This is still an integral 'int', but it may be
1401 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1402 ASN-1 compiler as well as programs has been updated to use the new types.
1404 --- 3.0.46 2009/06/08
1406 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1407 only the bibliographic record was rendered. For type=opac, an OPAC
1408 record is only returned if it is present.
1410 iconv: small fix for encoding of advancegreek.
1412 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1414 yaz-client: option auto_reconnect=on really reconnects.
1416 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1418 server: avoid null ptr ref for for yaz_poll errors.
1420 build: fix RPM build for RHEL 5.3.
1422 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1424 --- 3.0.45 2009/03/31
1426 Fixed bug #2709: TCP connect returns Invalid argument.
1428 Fixed compilation for mingw.
1430 Honor charset for raw records (ZOOM_record_get).
1432 Fixed use of errno for threaded mode that was seen on Solaris 10.
1434 Fixed argument passing with blanks in value for Windows Service.
1436 Disable YAZ' own log rotate by default (no 1 GB limit).
1437 The variable l_max_size which specifies the log file limit is set to 0
1438 (DISABLED): This is due to the fact that YAZ is most often deployed using
1439 logrotate. Also YAZ can not perform log rotate because of unsufficient
1440 permissions (setuid).
1442 --- 3.0.44 2009/02/17
1444 List supported encodings in man page for yaz-iconv.
1446 Fixed missing SSL libs for --libs output
1448 Re-established OID record syntax application-xml. Nobody should use it
1449 but we don't want to change soname because of this symbol being absent.
1451 --- 3.0.42 2009/02/02
1453 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1455 Added member named_result_sets for init handler struct for the GFS. This
1456 allows a server to disable named result sets.
1458 Removed OID record syntax application-xml.
1460 Added support for rule-based transliterator for ICU wrapper of YAZ.
1462 Fixed bug #1902: yaz-icu XML output.
1464 Make YAZ checks Emacs friendly.
1466 BITSTRING value shows value. Bug #2346.
1468 ISO2709 decoding: skip control characters from indicator data.
1470 Omit sort key by default in yaz-icu's output.
1472 Allow combined single char options (again) for YAZ' options function.
1474 Utility yaz-marcdump got option to display YAZ version (-V).
1476 Allow YAZ to use ICU 3.4.
1478 Added new ICU test case which illustrates removal of diacritics.
1480 --- 3.0.41 2008/12/29
1482 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1484 --- 3.0.40 2008/12/29
1486 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1489 Fixed bug #2352: yaz-marcdump crashes for certain record.
1491 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1493 Added support for Danmarc2 to UTF-8 conversion.
1495 Added support for ISO5426 to UTF-8 conversion.
1497 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1498 implementation version.
1500 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1502 --- 3.0.38 2008/11/10
1504 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1505 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1507 ZOOM C now interprets databaseName option for ZOOM connection as path
1510 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1512 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1514 Dummy Libxml2 types no longer defined in headers of YAZ'.
1516 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1519 --- 3.0.36 2008/09/26
1521 Various ODR chapter fixes.
1523 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1525 Added missing source for Windows compilation, mutex.c.
1527 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1529 For SRU connections in ZOOM all records up to "count" are now fetched.
1531 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1532 in Windows due to bad error handling for Libxml2.
1534 Added facility for sending arbitrary records (ASN.1 any) using
1535 ZOOM C's Extended service update. Patch by Sam Reynolds.
1537 New options for ZOOM C's connection, logapdu which makes ZOOM log
1540 --- 3.0.34 2008/06/18
1542 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1544 --- 3.0.32 2008/06/12
1546 Fixed memory violation that could occur when decoding UTF-8. This bug
1547 was only present in 3.0.30 of YAZ.
1549 --- 3.0.30 2008/06/06
1551 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1552 GNU TLS is used by default (if found).
1554 yaz-ztest returns OPAC records if a client asks for OPAC.
1556 Improved speed of MARC-8 encoding.
1558 Added support for lossy and loss-less MARC-8 encoding.
1560 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1562 Added new Windows Service wrapper (sc).
1564 yaz-client's itemorder command may now send a file.
1566 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1568 Added new function yaz_log_xml_errors.
1570 Allow (but warn) unknown XML attributes in MARCXML parsing.
1572 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1574 The UTF-8 to MARC-8 conversion now uses a different set of characters
1575 for Greek symbols. Bug #2120.
1577 --- 3.0.26 2008/02/21
1579 Added yaz_daemon (daemon.h).
1581 Fixed bug #2068: pkg-config trouble
1583 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1585 --- 3.0.24 2008/01/28
1587 Document --with-xml2 option.
1589 Added OPAC XML XSD (etc/opacxml.xsd).
1591 Allow glob mask for name attribute in retrieval element for the
1592 generic frontend server's retrieval facility.
1594 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1595 except POLLIN/POLLOUT.
1597 Fixed error handling in cs_listen. Bug #2037.
1599 --- 3.0.22 2008/01/20
1601 Fixed version in yaz/yaz-version.h.
1603 Fixed bug #2027: Crash when closing connection.
1605 Changed configure so that ICU support is only enabled if only ICU
1606 and Libxml2 is available (because the ICU chain is XML based).
1608 --- 3.0.20 2008/01/15
1610 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1611 is built. Only this DLL depends on the ICU runtime.
1613 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1614 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1616 Changed license of CCL module to 'Revised BSD'. After consultation with
1617 remaining members of the original EUROPAGATE consortium, we are re-issuing
1618 the CCL module without a separate license. The software was developed by
1619 Index Data as part of a research project. The special license was included
1620 to help feed usage information back to the project consortium to support
1621 project evaluation. At this time, the project consortium has long-since
1622 disbanded, and the majority of the original principals have retired. At the
1623 same time, we have significantly modified the software during the following
1624 years, to the point where very practically no original code remains. To
1625 simplify re-use of the software, we have contacted those members of the
1626 consortium who could be reached, and agreed to re-issue the module as a
1627 proper part of the YAZ package.
1629 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1631 CQL closer to being version 1.2 compliant. CQL also allows free-form
1632 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1635 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1636 bug could make Extended services handling crash in the ZOOM layer. This
1637 bug was only present in YAZ 3.0.18.
1639 --- 3.0.18 2007/12/19
1641 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1644 yaz-marcdump reads and writes collection wrapped records.
1646 Handle OPAC for record conversion module.
1648 Fixes for ICU wrapper.
1650 Allow ICU libs to be controlled with --with-icu .
1652 --- 3.0.16 2007/11/12
1654 Added yaz_poll which is a wrapper for select/poll. When poll is available
1655 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1656 sockets to be in use.
1658 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1659 functionality through an XML based configuration (ICU chain). This system
1660 is useful for search facilities such as Pazpar2 and Zebra that needs to
1661 perform tokenization of indexed material. The ICU code in a separate
1662 library libyaz3_icu.a.
1664 Added HTTP tunnel facility for COMSTACK, bug #1752.
1665 This is a facility that allows a Web proxy, such as squid, to tunnel
1666 Z39.50 traffic. This facility is "transparent" to must applications
1667 using YAZ. It's enabled by using pseudo transport connect: followed by
1668 the proxy address, followed by command, then follwed by he regular
1669 "virtual" addresss. For example,
1670 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1672 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1674 --- 3.0.14 2007/09/21
1676 Fixed bad memory reference in ZOOM_record - cuased by member not being
1677 initialized. This was a problem only in YAZ 3.0.12.
1679 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1680 fields were not removed.
1682 Changed the way C code is generated from codetables.xml. Made a MARC-8
1683 conversion trie for each characterSet section rather than codeTable.
1684 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1685 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1687 --- 3.0.12 2007/09/12
1689 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1690 from ZOOM_record_error).
1692 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1694 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1696 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1698 Better SRW-to-Bib-1 diagnostic mapping.
1700 ZOOM C and yaz-client announces SRU version 1.2 by default.
1702 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1705 Fixed in yaz_sru_decode to allow other version than 1.1.
1707 --- 3.0.10 2007/08/22
1709 Added support for SRU scan for ZOOM.
1711 Added support for the use of the older versions or Extended Service
1712 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1713 set to the version , 1=first, 2=second, 3=third. The third version is
1714 what ZOOM C has used so far. And that, obviously, is the default.
1716 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1717 therefore in Zebra and in SimpleServer-based applications). The new
1718 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1719 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1720 which is passed into the back-end search callback function.
1722 Added support for HTTP Basic authentication in clients: the SRU/W
1723 codec encodes the username/password elements of the PDU structure
1724 appropriately, and these may be set using the "user" and "password"
1725 options in ZOOM-C applications (the same options that are used for
1726 Z39.50 authentication).
1728 --- 3.0.8 2007/06/25
1730 Fixed bug #1208: SSL appears to be broken in ZOOM.
1732 Fixed bug #1206: Libxml2 include path weirdness.
1734 Added oid_name_to_dotstring.
1736 Allow elementSetName to be specified for ZOOM C record update.
1738 Allow waitAction to be specified for ZOOM C based for Extended Services.
1740 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1741 syntax OID. Bug introduced in YAZ 3 series.
1743 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1745 --- 3.0.6 2007/06/06
1747 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1748 directory. yaz-client now reads commands from file given by option -f
1749 if specified; then tries to read .yazclientrc in current directory.
1750 Failing that, it reads .yazclientrc from user's home directory.
1752 Added support for correlationInfo Note and ID for Record Update via
1755 Added yaz-client command querycharset which specifies character set for
1756 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1757 (termListAndStartPoint).
1759 Charset ISO5428:1984 is an alias for ISO5428-1984.
1761 Implemented a way to perform scan in a result set using Z39.50. This
1762 is achieved by attaching the result set name in the characterInfo
1763 (type InternationalString) of OtherInformation in the Scan Request PDU.
1764 The result set is identified in the otherinformation by the new OID:
1765 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1766 This allows for scan in result set and faceted search . Zebra did some
1767 of this in the APT term using attribute type 8 and value being result
1768 set. Using the OtherInformation approach for this is cleaner and easier
1769 to work with in proxies and the like. This facility can be used in
1770 yaz-client using new command setscan which takes a result set as first
1771 argument, start position (APT) as second.
1773 Changed decoding of SRU XML packed records to deal with servers that
1774 have recordData with XML data with multiple root nodes. Also make
1775 comparison for recordPacking case insensitive. Again, one server
1776 returns "XML" where others return "xml".
1778 For SRU responses allow Content-Type application/xml as well as text/xml.
1780 --- 3.0.4 2007/05/21
1782 Fixed bug in character set conversion of BER strings. Bug introduced
1785 --- 3.0.2 2007/05/08
1787 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1789 For OID class, use oid_class consistently.
1791 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1794 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1795 character set for bibliographic information interchange". By Giannis Kosmas.
1797 Added documentation on new OID API.
1799 --- 3.0.0 2007/05/02
1801 Changes to generic frontend server interface: added new member
1802 'query_charset' for bend_initrequest structure. A backend init handler
1803 should set this member to its native character set for query terms.
1804 When defined, the frontend server logic will announce this character set
1805 to a client if the negotiationModel bit is set by the client. All server
1806 implementors are encouraged to specify this. If a backend server does not
1807 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1809 Added CCL utility to remove terms (stop words) from resulting RPN
1810 tree. This is handled by functions with prefix ccl_stop_words_ .
1812 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1813 terms in RPN queries.
1815 Clean-up the CCL API. Moved some internal structures from ccl.h to
1816 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1817 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1818 This is replaced by ccl_parser_find_str which takes a string instead.
1820 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1821 libyaz.la is the core of YAZ except the generic frontend server and
1822 does not depend on POSIX threads anymore. libyaz_server.la is the
1823 generic frontend server facilities and uses POSIX thread functionality
1824 if available. The libyaz.la no longer depends on POSIX threads because
1825 the number of global structures is limited. NMEM no longer re-uses blocks
1826 between threads ; it simply free's memory immediately but allocates in
1827 "large" chunks as usual. We don't expect any performance penalties
1828 because of this. The yaz_log system is still using a global log_level so
1829 caution must be taken when modifying it with yaz_log_init_.. +
1830 yaz_log_mask_str. This, however, should not cause any trouble because
1831 these functions are called during initialization of application code
1832 anyway. `yaz-config --libs server` returns libs for server applications;
1833 `yaz-config --libs` returns libs for non-server applications.
1835 New OID database - with public definitions in oid_db.h. Removed old OID
1836 database including the head oid.h and definitions such as enum oid_value
1837 and struct oident. The new OID database uses the same string names as
1838 before but the 'protocol' is gone. There are now only two representations
1839 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1840 converts from string to OID; functions with prefix yaz_oid_to_string
1841 converts the other way.
1843 Change to emit_term() in CQL-to-PQF query translation: when a term has
1844 the /regexp relation modifier, do not process it for leading and
1845 trailing "^" and "*", which have quite different meanings in regular
1848 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1849 write handlers no longer carries a 'last' parameter. This will make
1850 yaz_iconv flush "less" characters. A flush is performed by call to
1851 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1853 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1854 removed, because function yaz_query_to_wrbuf does the same.
1856 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1857 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1859 Deprecated MARC utility functions removed.
1861 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1864 Branch split: YAZ_2_1_55_branch
1866 --- 2.1.54 2007/03/16
1868 Fix to ZOOM-C so that transparent reconnection is properly handled on
1869 connections that are in asynchronous mode.
1871 Fixed compilation on OpenBSD 4.0.
1873 Large strings in GRS-1 records are now properly displayed in yaz-client.
1875 Added character conversion support for "advancegreek"; based on patch from
1878 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1879 sequence is met. Before the error was not set so it would be unknown.
1881 Adjust yaz-marcdump MARC reader so that it skips until record separator
1884 --- 2.1.52 2007/03/07
1886 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1887 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1888 fd_set structure used as a bitmask for the FDs to be selected on.
1890 Using ACX_PTHREAD macro to check for POSIX threads.
1892 Fixed have-vsnprintf check.
1894 --- 2.1.50 2007/02/23
1896 Fixes for configure on BSD. Bug #900.
1898 Added snprintf/vsnprintf wrappers for systems that don't have
1899 limits (heavens forbid).
1901 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1902 created before all previous tasks were completed and removed from the
1903 task queue, the new task could be removed by a mistake.
1905 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1907 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1909 Fixed bug #832: Problem with MARC/charset in yaz-client.
1911 Fixed bug #668: save command line history for yaz-client.
1913 Fixed bug #830: pkg-config support.
1915 --- 2.1.48 2007/01/23
1917 Extended ZOOM result set options with two options that may be read by
1918 a client: resultSetStatus and presentStatus with values as specified for
1920 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1922 Fixed bug #827: Using SSL fails on Debian etch.
1924 Fixed bug #826: Weird looking chars for set of MARC records.
1926 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1927 that is treated as an ItemOrder with itemRequest being an XML document
1928 external. The value of "doc" is the content.
1930 Extended the GFS search facility. New member of bend_search_rr
1931 'estimated_hit_count' signals that hits is known to be an estmate
1932 (higher or lower than real hit count). New member 'partial_resultset'
1933 signals that the search was partial (hit count is lower or equal than
1934 real hit count). For Z39.50, the information is stored in resultSetStatus
1935 member of SearchResponse APDU. For SRU, the information is signalled
1936 via SRU diagnostic 59: "Result set created with valid partial results
1939 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1941 --- 2.1.46 2007/01/13
1943 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1945 Added ZOOM_connection_peek_event.
1947 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1948 the following new functions:
1949 ZOOM_event_nonblock, ZOOM_connection_process,
1950 ZOOM_connection_get_{socket,mask,timeout},
1951 ZOOM_connection_fire_event_{timeout,socket}.
1952 The existing blocking event handler, ZOOM_event, is a wrapper for the
1953 + blocking ZOOM_event_sys_{poll,select}.
1955 Implemented function ccl_xml_config which parses XML version of CCL
1956 configuration (bug #798).
1958 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1960 Added timings utility (yaz/timing.h)
1962 --- 2.1.44 2007/01/03
1964 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1967 Fixed bug #779: Rotation of apdu.log fails.
1969 Fixed for character set conversions:
1970 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1971 Honor G1 set in MARC-8 decoding.
1973 --- 2.1.42 2006/12/17
1975 Fixed bug #775: char conversion does not handle Alternative UTF-8
1978 Implemented function yaz_marc_read_line which parses MARC line format
1979 records. There is a wealth of formats out there. So far, this function
1980 reads line records produced by yaz_marc_write_line.
1982 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1983 more generic and easier to remember(!) options: -i format and -o format
1984 which specifies input format and output format respectively - where
1985 format is one of "marc", "marcxml", "line", "marcxchange".
1987 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1988 does not print anything except warnings for records.
1990 For yaz-marcdump, added support for MARC split into files (-s) with a given
1993 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1994 spec, at http://www.loc.gov/standards/sru/record-update/
1995 This has changed the binary layout of the following structs:
1996 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1997 bend_update_rr . Patch by Ko van der Sloot.
1999 Added GFS utility function bend_assoc_is_alive which returns 1 if
2000 association is still alive (client is connected); 0 otherwise (client
2001 closed connection). This allows busy servers to stop working for
2004 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2005 been a separate piece of software. This version of ziffy has been modified
2006 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2008 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2010 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2011 Client code may now interrogate options such as "init_opt_sort" to
2012 find out whether the server claims to support various options.
2014 --- 2.1.40 2006/11/27
2016 Added utilities yaz_{set,get}_esn to set/get element set name from
2019 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2020 of YAZ and has been so since YAZ 2.1.10.
2022 Implemented ZOOM_record_error which returns error information for
2023 record (surrogate diagnostic).
2025 --- 2.1.38 2006/10/31
2027 Updates for SRU Update by Ko van der Sloot:
2028 1. Changed name from "operation" to "action"
2029 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2030 versions in the code, marked as 'backward compatible'.
2031 3. Added diagnostics for SRU Update.
2033 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2035 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2037 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2039 For GFS, fixed problem with SRU diagnostic 'First record position out of
2040 range' being issued for 0 hits.
2042 zoomtst10 part of Windows Build.
2044 --- 2.1.36 2006/10/13
2046 Implemented yaz_filepath_comp which splits a path into file path
2047 components (required by Zebra 2.0.3+).
2049 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2050 BSD inspired license until now so this should not have any real impact on
2051 anybody. See http://www.opensource.org/licenses/bsd-license.php
2053 Fixed bug #687: Missing log lines.
2055 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2058 Fixed bug #689: SRU diagnostics to be added.
2060 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2061 whether a connection is idle (no more work do do).
2063 --- 2.1.34 2006/10/04
2065 Change type of optval from long to int for invocation of setsockopt with
2066 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2068 Added support for specifying the max log file size for the Generic
2069 Frontend Server. The size is given with option -r.
2071 --- 2.1.32 2006/09/21
2073 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2075 --- 2.1.30 2006/09/17
2077 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2080 Fixed bug in Generic Frontend Server that could cause a server to stop
2081 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2083 For the generic frontend server, the maximum record size is used as maximum
2084 size of incoming packages (SRU + Z39.50). The value until was previously
2085 only used in Z39.50 Init negotiation and, later, in a session controlled
2086 sizes of records returned. This is controlled using -k option. It can be
2087 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2089 --- 2.1.28 2006/09/04
2091 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2094 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2096 New option for yaz-marcdump -lpos=value which allows setting a portion
2097 of MARC header to a certain value.
2099 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2101 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2102 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2104 --- 2.1.26 2006/08/15
2106 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2109 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2111 --- 2.1.24 2006/08/08
2113 Fixed MARC ISO2709 encoding routines to deal with character set
2116 Minor changes to GFS logging. Database included in search request log
2119 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2120 cached/multiple records.
2122 Shared libraries are built by default on Unix+configure.
2124 Changed cql2pqf transformation to use a different evaluation order. The
2125 new order is: always, relation, structure, position, truncation, index
2126 and relationModifier. Old order was: always, relation, relationModifier,
2127 structure, index, position, truncation. Note that the the latter ones
2128 override former ones for identical attributes.. The new scheme means that
2129 it is possible to override any existing attribute with a relationModifier.
2130 And also that it is possible to override everything for the index rule
2131 (except the ones listed in relationModifier). No order is perfect but this
2132 one, we believe, covers more real cases.. The "always" should have been
2133 called "default", since the attributes there can be overridden with all
2136 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2137 compilation phase, but also for yaz-config --cflags output. This allows
2138 us to have public headers with Libxml2 stuff in them . It should also,
2139 eventually, make Libxml2 checks redundant in packages using YAZ, such
2142 --- 2.1.22 2006/06/15
2144 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2145 stored in uri, message and details.. Previously diagnostics were stored
2146 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2147 compatibility.. but he's probably the only one affected, so.
2149 Added support for CCL, compiled on the client side, in ZOOM-C. This
2150 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2151 input; the resulting query objects can be used for for searching with
2152 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2154 YAZ' configure searches for OpenSSL by default.
2156 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2157 SL_CTX_use_certificate_file. See
2158 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2159 for more info. Thanks to Ko van der Sloot.
2161 --- 2.1.20 2006/06/02
2163 Bug #600: SRU GET, POST support for yaz-client. Introduced
2164 command 'sru' which selects method SOAP/GET/POST.
2166 Allow missingValueAction to be specified for the sortspec string -
2167 function yaz_sort_spec. By default, the missing value action is null.
2168 Use ! to specify "abort". Use = followed by stringvalue to specify default
2171 Ensured that Present-handler (if defined) is called in GFS before any call to
2172 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2173 searchRetrieve requests.
2175 Documentation for YAZ is now based on the Docbook XML/XSLT using
2176 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2177 is no longer depending on jade/openjade or docbook-to-man scripts.
2178 PDF is no longer part of the distribution - but can optionally be
2179 made using DSSSL/jadetex or FOP.
2181 Added retrieval handling support in Generic Frontend Server to support
2182 conversion between MARC/XML as well as XSLTtransforms. See
2183 etc/yazgfs.xml for an example.
2185 Added Authentication support to Generic Frontend Server in SRU
2186 mode. Authentication using HTTP Basic is supported, as is the use
2187 of 'x-username' and 'x-password' parameters in the request itself.
2189 Added support for a new character set MARC8s identical to MARC8 except
2190 that it converts combined characters to single Unicode characters in the
2191 Latin-1 range (when possible).
2193 --- 2.1.18 2006/04/24
2195 ASN.1 compiler 0.4: generates brief Doxygen file header for
2196 generated .h/.c files.
2198 Utility yaz_iconv now supports conversion to MARC-8.
2200 New facilities for the MARC module. The reading - and writing of
2201 content are separate methods for the yaz_marc_t handle. The following
2202 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2203 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2204 format). Write functions have prefix yaz_marc_write_.. The existing
2205 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2206 available. Removed support for OAI-MARC and simplexml (not the
2207 simplexml from PHP5).
2209 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2210 to be returned for this connection.
2212 --- 2.1.16 2006/03/31
2214 Allow multiple languages and charsets to be specified with
2215 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2216 negcharset iso-8859-1,utf-8
2218 Translation of proximity nodes from CQL into PQF now works.
2220 Moved to automake 1.8, 1.9.
2222 Added function yaz_log_set_handler which allows a log handler to be
2223 installed. This handler will be called for all log messages. Output
2224 to file is also produced; but that can be disabled by passing NULL
2225 fname to yaz_log_init_file.
2227 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2229 For SRW (including GFS), accept application/soap+xml as content-type
2232 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2233 produces NO stylesheet reference even if a default stylesheet is specified
2236 --- 2.1.14 2006/03/14
2238 Updated Windows package to include yazd.dll + yazd.lib for the
2239 Development component.
2241 If the environment variable YAZ_LOG is set, then it is used as a
2242 string indicating the default level of logging to use if not
2243 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2244 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2245 used as before. So, for example, to omit warnings from YAZ logging,
2246 export YAZ_LOG=-warn
2248 cql_transform() now map structure and other attributes before indexes,
2249 so that index-specific structures and other attributes can override
2250 defaults. So now a combination of mapping specifications such as:
2252 index.dc.date = 1=date-modified 4=5
2253 does the right thing.
2255 cql_transform() now also respects the "always" mapping specification,
2256 which establishes an initial set of attributes to be used for all
2257 terms except where overridden by more specific attributes associated
2258 with the index, relation or modifier.
2260 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2261 which mode to use; one of "post", "get" or "soap" (SRW, default).
2263 Fixes for yaz_iconv routines: changed trie-based character set conversions
2264 to use only non-negative values for bit fields due to Sun's C compiler not
2265 supporting negative values.
2267 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2268 sequences where not read correctly. Fix by Rustam Usmanov.
2270 Updated win/makefile to use options, settings which makes things
2271 compile with VS C 2005.
2273 --- 2.1.12 2006/02/01
2275 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2277 In ZOOM socket code, use select instead of poll on MacOSX.
2279 ZOOM-C now support client-side compilation of CQL into RPN that is
2280 sent to the server, enabling CQL to be used against all Z39.50
2281 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2282 ZOOM_query object, and submit it using ZOOM_connection_search().
2283 The CQL-to-RPN translation uses a configuration file, the name of
2284 which must be specified in the Connection's "cqlfile" option.
2286 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2287 function, which takes as its start-term parameter a ZOOM_query object
2288 (which may have had either CQL or RPN set into it).
2291 --- 2.1.10 2005/11/29
2293 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2294 GFS to support this as well. Backend handler, bend_srw_update, does the
2295 update work. Code contributed by Ko van der Sloot.
2297 Allow retrieval of Search Result-1 information in ZOOM by the use of
2298 options that are attached to a result set. ZOOM documentation updated
2301 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2302 UTF-8 conversion. Patch by Raj Patel.
2304 Added option -m to GFS to control formatting of timestamps in log file.
2306 Added 'exit' as synonym for 'quit' in yaz-client
2308 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2309 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2310 for the new members. Patch by Ko van der Sloot.
2312 Added support for SRU POST. It is supported for content-type
2313 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2315 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2316 Instead make the library libyaz.la multi-threaded. Threading as a whole
2317 can still be disabled by configure option --disable-threads. Previosly,
2318 with older GLIBCs there were problems with MT libs under Apache. This
2319 has now been fixed a long time ago.
2321 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2324 CQL module modified to be case insensitive for relations/indexes/operations.
2326 Fixed bug in CQL transform code: incorrect value relationModifieder
2329 Added 'show all' command for yaz-client which retrieves all results
2332 Added new yaz-client, xmles, which takes a (private) OID and
2333 a document to be sent as an extended service request.
2335 Describe new yaz-client commands wait_response and set_auto_wait.
2337 Increase TCP/IP listener backlog from 3 (which I am guessing was
2338 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2339 that the socket will queue as many incoming connections as it's able
2340 to handle ongoing connections. In other words, it will never now
2341 refuse a connection that it would be able to handle merely because
2342 it's not got around to accepting() enough of the pending connections
2343 yet. This is the behaviour anyway under Linux, where the listen()
2344 argument is ignored; but not under BSD and on systems such as
2345 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2346 YAZ-based servers should now be uniform across operating systems in
2349 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2350 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2351 This allows yaz-marcdump to read large MARC batches (>2 GB).
2353 Modified all YAZ source files - except the source which is auto-generated
2354 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2357 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2358 corresponding to the existing *_setl() function. These allow option
2359 values containing arbitrary valuues.
2361 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2362 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2363 except that it returns an indicator of whether or not the sort
2364 criterion was accepted (0 for OK, -1 for invalid).
2366 --- 2.1.8 2005/06/07
2368 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2369 MARC output rather than returning "new" buffer.
2371 yaz-client warns about unknown init options.
2373 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2375 --- 2.1.6 2005/05/24
2377 Added support for SRW sort in Generic Frontend Server. Patch
2378 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2379 sortKeys - or NULL if none is provided.
2381 Fixed bug #307: It was impossible to specify indefinite/no timeout
2382 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2385 Added support for multiple languages and charsets to be specified in
2386 ZOOM. Each charset/language is separated by a blank. If negotiation is
2387 in effect in init-response, Option
2388 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2389 Code based on patch by Vasiliy Osadchuk.
2391 Fixed bug #306: infinite recursion that occurred when calling
2392 yaz_log_level_init as the first call (before other log level or
2395 Fixed bug in scan handling in front end server: if preferred-Position-In-
2396 Response was non-present, a NULL pointer referece was performed.
2398 --- 2.1.4 2005/04/26
2400 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2401 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2402 now defined for all those error codes. So instead of putting 109 in
2403 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2404 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2406 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2409 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2411 Program yaz-client now exits and produces an error message if multiple
2412 Z39.50 servers are specified on the command line (none or one allowed
2415 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2418 --- 2.1.2 2005/03/16
2420 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2422 Fixed bug #272: Preserve spacing for CCL terms.
2424 --- 2.1.0 2005/03/14
2426 Added support for virtual hosts and multiple backend servers for
2427 the YAZ frontend server. The configution is XML based and
2428 support specificition of CQL to RPN mappings and explain information.
2429 See section "Virtual Hosts" in the YAZ manual.
2431 Extended OPAC display utility. OPAC display utility renders
2432 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2433 to supplement yaz_marc_decode_wrbuf.
2435 Fixed a bug in MARC decoder that could caused it to crash for some
2436 invalid MARC records. More diagnostics and warnings where added in
2437 XML output (warnings, etc are stored in comments).
2439 --- 2.0.34 2005/02/08
2441 Fixes for UNIX domain sockets. Bug #261.
2443 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2445 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2446 Added yaz_marc_subfield_str which defines subfield lead string which is
2447 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2448 yaz_marc_endline_str which defines end of fields string used in
2449 YAZ_MARC_LINE format. Default string is newline.
2451 Experimental support for MarcXChange. This format can be produced
2452 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2453 http://www.bs.dk/standards/MarcXchange.xsd
2455 Added yaz-client commands scansize that sets maximum number of
2456 entries to be returned by scan.
2458 --- 2.0.32 2005/01/11
2460 Added support for SRW scan in yaz-client and Generic Frontend Server.
2462 * Added whereInList member to SRW Scan Term.
2464 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2466 Fixed NMEM system to return aligned blocks on the smallest boundaries
2467 that are suitably aligned for all possible types on the particular
2468 architecture YAZ is being built for.
2470 --- 2.0.30 2005/01/04
2472 Fixed numerious warnings that was issued with newer versions of GCC.
2474 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2475 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2478 Make YAZ Generic Frontend Server slightly faster.
2480 Enhance (and reduce) logging for Generic Frontend Server.
2482 Revert YAZ log system so that it flushes every write operation
2483 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2485 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2486 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2487 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2488 will effectively disable old definitions.
2490 --- 2.0.28 2004/11/09
2492 Added yaz_log_time_format which specifies log format using
2495 Added yaz_log_module_level which returns mask for a module. Value
2496 is non-zero mask a if module is enabled; zero if disabled.
2498 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2499 in include/yaz/cql.h.
2501 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2503 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2505 Fixed bug #172: RPM builds does not enable SSL.
2507 Doxyfile.in part of dist. Doxyfile generated by configure.
2509 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2510 are given and the corresponding component does not exist.
2512 Extend CCL documentation in YAZ reference. Describe r=r.
2514 --- 2.0.26 2004/10/01
2516 Fixed MARC->MARCXML conversion to properly deal with
2517 fields, subfields, indicators having non-ASCII characters.
2519 Fixed MARC->MARCXML conversion so that ASCII control characters
2520 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2523 Added YAZ GFS support for conversion from Z39.50 surrogate
2524 diagnostics to SRW surrogate diagnostics.
2526 Bug fix: YAZ GFS did not return schema in explainResponse.
2528 --- 2.0.25 2004/09/30
2530 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2531 now converts recordSchema to elementSetName as well as schema URI.
2533 Fixed bug in COMSTACK that prevented HTTP request packages from being
2536 --- 2.0.24 2004/09/29
2538 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2539 does not require white-space before and after the dash in a range, e.g.
2540 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2543 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2544 due to new GCC removing "redundant" code.
2546 Added yaz-client commands scanpos and scanstep that sets preferred
2547 position and step-size for scan.
2549 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2551 Added CCL utility ccl_qual_buf which parses one or more CCL
2552 spec lines in a buffer.
2554 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2555 of name and value - ignoring empty lines and comments.
2557 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2559 Added odr_get_element_path which returns current element path for an
2560 ODR handle. This utility is useful in error handling or user-defined
2563 Added ODR_PRINT utility odr_set_stream which is is a more generic
2564 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2565 to a write function and pointer to close function. The close function - if
2566 non-NULL - will be called during odr_destroy.
2568 Fixed bug in CCL parser where truncation char was not removed from
2569 right side when truncation=both was in effect.
2571 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2574 --- 2.0.23 2004/08/11
2576 Fix buffer overrun in CQL parser when dealing with proximity (%).
2578 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2579 to UTF-8/UCS conversion is now only based on codetables.xml.
2581 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2583 --- 2.0.22 2004/08/06
2585 Add support for more "commit changes" in ZOOM (uses Extended Services).
2587 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2590 Yet another small fix for configure of SSL.
2592 --- 2.0.21 2004/05/14
2594 Fix SSL libs for configure when --with-openssl=DIR is given.
2596 --- 2.0.20 2004/05/10
2598 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2600 SSL comstack now uses yaz.pem certificate file on server side
2601 by default. Certificate filename can be configured by calling
2602 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2604 Fix bug regarding multiple calls to ZOOM_connection_connect.
2606 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2608 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2609 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2611 ZOOM now allows inspection of X509 peer certificate for verification.
2612 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2614 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2615 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2616 as "modular" but it simplifies things.
2618 Added cs_get_peer_certificate to that returns peer X509 PEM.
2620 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2621 NULL if SSL is unavailable.
2623 Documentation about MARC decoding tools.
2625 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2627 --- 2.0.19 2004/03/30
2629 Rename CHANGELOG to NEWS to follow GNU style packing.
2631 Fix bug with missing initialization of member in init_diagnostics.
2632 This bug affects threaded version of GFS server.
2634 --- 2.0.18 2004/03/20
2636 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2639 Ensure zlib.dll is packed with Windows install.
2641 --- 2.0.17 2004/03/17
2643 Fix encoding of xsd:string to use text instead of CDATA.
2645 Fix endless loop in CQL parser with unbalanced ".
2647 Use a more compact way to store MARC-8 conversion tables.
2649 --- 2.0.16 2004/03/16 Debian only
2651 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2654 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2659 --- 2.0.15 2004/03/01
2661 Another fix for decoding of XML packed records.
2663 --- 2.0.14 2004/02/25
2665 Fixes for Chunked encoding. White space not ignored after length spec.
2667 Update NS and use default NS for SRW diagnostic elements.
2669 --- 2.0.13 2004/02/23
2671 Implement ZOOM_resultset_cache_reset which resets record cache.
2673 Implement ZOOM_resultset_sort which sorts a result set.
2675 Implement chunked HTTP transfer.
2677 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2679 --- 2.0.12 2004/02/16
2681 Added member 'schema' to bend_explain_rr structure so that backend
2682 can specify explain record identifier. Defaults to Zeerex 2.0.
2684 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2686 --- 2.0.11 2004/02/16
2688 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2691 Added init command for yaz-client which sends "extra" init request.
2693 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2694 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2696 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2698 Make ZOOM error code for "invalid query".
2700 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2702 --- 2.0.10 2004/02/05
2704 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2707 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2709 Added option -p <file> to make Generic Frontend Server to write PID file.
2711 Added option -D to put Generic Frontend Server in background on its own.
2713 Make ZOOM C recognize option "password". If unset, "pass" is used
2714 (for backwards compatibility).
2716 Fixed a bug in Generic Frontend Server that could make it crash if a
2717 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2720 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2721 Must be issued before open, in order to be in effect.
2723 --- 2.0.9-6 2004/01/12 Debian/Windows
2725 Make the SRU server more picky WRT unknown params, etc.
2727 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2729 New YAZ client command, options, that sets Z39.50 options.
2731 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2732 options from a string of tokens (one token for each option bit).
2734 Update SRW diagnostic code messages.
2736 --- 2.0.9-5 2004/01/07 Debian/Windows
2738 Handle user defined stylesheet for SRW/SRU.
2740 --- 2.0.9-4 2004/01/06 Debian/Windows
2742 Fix bug in decoding of Content-Length.
2744 --- 2.0.9-3 2004/01/06 Debian/Windows
2746 Fix a bug with decoding of XML packed records.
2748 --- 2.0.9-2 2004/01/05 Debian only
2750 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2752 Fix bug in SRW/SRU diagnostics decoding.
2754 --- 2.0.9 2004/01/05
2756 Fixed bug in Generic Frontend Server which could drop records exceeding
2757 preferred message size. Reported and fixed by Irina Dijour.
2759 Fixed calculation of package size for structured records in Generic
2760 Frontend Server. Reported and fixed by Irina Dijour.
2762 Fixed namespace for SRW/SRU diagnostics.
2764 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2766 --- 2.0.8 2003/12/22
2768 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2769 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2772 CQL changes to reflect recent changes to the specification:
2773 * Documentation talks about context sets instead of index sets.
2774 * Documentation talks about indexes instead of qualifiers.
2775 * The CQL-to-PQF transformer's configuration file now uses
2776 "index.set.name = <attributes>" instead of the old form
2777 "qualifier.set.name = <attributes>". (Both forms are still
2778 understood but the latter is deprecated.)
2779 * CQL terms with no explicit index specified are now interpreted as
2780 cql.serverChoice instead of srw.serverChoice (which of course
2781 behaves exactly the same.)
2783 --- 2.0.7 2003/12/16
2785 MARC conversion can now generate ISO2709 output in another
2786 character set. yaz-marcdump uses this facility if you invoke it
2789 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2790 functions from there can be used from C++.
2792 --- 2.0.6 2003/12/04
2794 Frontend server now transfers memory from decoded packages to stream
2797 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2798 references to show up.
2800 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2801 the ZOOM Abstract API. The older names for the same options are still
2802 also supported for the benefit of old applications.
2804 ZOOM-C supports "implementationId" and "implementationVersion" options
2805 to go along with "implementationName". These allow the user code to
2806 specify identification strings to be sent to servers.
2807 Add OID for the new ExtLite attribute set.
2809 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2810 as requested/supplid by Ere Maijala <ere@atp.fi>
2812 For generic frontend server, reverse the order of
2813 "toolkit-supplied / application-supplied" strings sent as implementationId,
2814 Name and Version. Also, remove the spaces around the slash. This brings
2815 the GFS in line with the behaviour of ZOOM-C on the client side.
2817 Add function ZOOM_scanset_display_term.
2819 yaz-client shows scan displayTerm if present.
2821 Utility yaz-iconv is now installed by default along with the man page
2824 Extend configure check for OpenSSL to use pkg-config where available (such
2827 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2828 server to specify uid/gid/mask for socket using the format
2829 unix:[user=uid,][group=gid,][umask=mask,]file=path
2830 If file= is omitted the existing format is assumed, e.g.
2832 in which case the mask is 0666 (rw for everybody).
2834 Major restructure of YAZ source. All source in libyaz is in src directory.
2835 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2836 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2838 Added man page for utility yaz-marcdump (used to be called marcdump).
2839 yaz-marcdump is installed by 'make install'.
2841 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2842 of incoming package failed.
2844 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2846 Change prototype of odr_perror: add const to message string.
2848 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2850 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2851 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2852 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2853 DNS lookup. There should not be any compatibility problems with this
2854 assuming that blocking=1 or 0 is used.
2856 Fix bad reference in UNIX comstack in function cs_addrstr.
2858 Fix for compilation on AIX.
2860 The generic front-end server (server/seshigh.c) now supports returning
2861 Init diagnostics to the client in User-information-field, in
2862 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2865 --- 2.0.4 2003/09/04
2867 Allow any CQL relation (not just all,any,exact,scr).
2869 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2870 that features the same UI.
2872 Implemented command update0 in YAZ client which is equivalent to
2873 update but uses old of Ext Update ASN.1.
2875 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2876 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2877 Previously no OID was used for this info.
2879 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2880 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2881 returns 'malformed search term' otherwise.
2883 SortResponse member resultCount now set to NULL in sort handler of
2886 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2889 Add three new utility functions for translating OIDs between various
2890 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2891 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2892 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2893 char *oid_to_dotstring(const int *oid, char *oidbuf);
2894 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2896 Reverted modifications for ES Update definition for z_IU0Update
2897 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2898 is back to YAZ 2.0.2.
2900 String value attributes for CCL parser.
2902 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2903 which their FirstSearch server returns in Init responses, sometimes
2904 carrying useful diagnostic information when Init fails. This has the
2905 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2906 "z39.50/oclcui.asn", where its definition is somewhat different from
2907 what OCLC document on their web-site, as required to interoperate with
2910 Support for anonymous authentication in yaz-client. Use the command
2913 * Fix the OID of the Index Data-local "admin" Extended Service from
2914 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2915 the 1000, which indicates a locally-defined OID, was a mistake.
2917 --- 2.0.3 2003/06/20
2919 Fix CCL directive @case handling so that it affects string match for
2920 both CCL keywords and qualifiers.
2922 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2923 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2924 Decoder has been updated with ASN.1 changes as listed in
2925 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2926 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2927 z_IUUpdate, remains unchanged.
2929 ZOOM_record_get may now return a record in a specific character set.
2930 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2931 "from" is the character set of record as returned by target. "to" is
2932 the character set to be returned. If omitted, "to" is UTF-8.
2934 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2936 New ODR utility, odr_getelement, which returns name of element for
2937 which encoding/decoding failed.
2939 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2940 in cases where a required element was omitted.
2942 Bug fix: some MARC8 sequences were not converted.
2944 New ZOOM option "step" which specifies number of records to be
2945 retrieved in one chunk. Used in conjunction with "start" and "count".
2947 SRW support for yaz-client. Use scheme http: to use it, e.g.
2950 yaz-client no longer does (un)intelligent character set conversions
2951 by default. Can be enabled with charset and marc_charset commands.
2953 xmalloc trace fix for 64-bit systems such as DEC alpha.
2955 Solaris 2.6 compile fix.
2957 New function, cql_strerror() translates SRW error codes, as returned
2958 by cql_transform_error(), into human-readable English strings. Used
2959 in yaz-client diagnostics when appropriate.
2961 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2962 converts it into a type-1 query which is sent to the server. This
2963 makes CQL available for use with all Z-servers, as opposed to the tiny
2964 minority that can handle CQL queries themselves.
2966 --- 2.0.2 2003/04/28
2968 New Debian package layout similar to the Redhat Package layout.
2970 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2971 and search result respectively.
2973 --- 2.0.1 2003/04/25
2975 Redhat package is now several packages: libyaz (runtime libraries),
2976 libyaz-devel (development and documentation, and yaz (utility programs).
2977 Package spec file by Morten Bogeskov.
2979 New member 'schema' in struct bend_fetch_rr which the name of requested
2980 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2981 handler MAY set this to reflect the schema of the returned record.
2983 New member 'display_term' in struct scan_entry. GFS now sets member entries
2984 and allocates scan entries to be filled by user scan handler. In previous
2985 version, entries member was allocated by the scan handler. That still works,
2986 but the GFS will ignore member display_term - assuming it was NOT set by
2987 the handler. The fact that the GFS now allocates the entries both allows
2988 for new members and makes a scan handler easier to write.
2990 Fix CQL lex buffer overflow.
2992 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2993 SRU default recordPacking is string.
2995 SRU protocol support for frontend server.
2997 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2999 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3001 Added scan for the ZOOM shell (zoomsh).
3005 * String Identifers for Schemas (Amendment 5).
3006 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3007 Old definition for schema
3008 Odr_oid *schema; /* OPT */
3013 Z_InternationalString *uri;
3014 #define Z_Schema_oid 1
3015 #define Z_Schema_uri 2
3018 * resultCount parameter to Sort Response (Amendment 1).
3019 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3021 Support for SRW 1.0 over HTTP. This is an optional feature and
3022 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3025 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3026 on the same port. SRW SearchRetrieveRequests are mapped
3027 to bend_init,bend_search,bend_fetch,bend_close.
3029 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3031 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3032 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3034 ZOOM connections are SRW based if schem http is used for hostname
3035 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3036 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3038 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3039 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3040 distance=n, order=true/false, relation=le, prox unit=word. If
3041 n is omitted, distance 1 is used.
3043 Fixed problem with C compiler include path in wrong order.
3045 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3046 on Solaris. Patch from Ko van der Sloot.
3048 New MARC decode API. All new functions operate on a yaz_marc_t
3049 handle. The most important new functions are: yaz_marc_create,
3050 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3051 decode and destroy respectively. Decoder can produce formats
3052 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3053 include/yaz/marcdisp.h.
3055 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3056 to UTF-8, UCS-32, wchar_t or Latin-1.
3058 * Prototypes for yaz_iconv_-functions moved to separate header
3059 include/yaz/yaz-iconv.h.
3061 Make a few private functions 'static' in unix.c. This prevents
3062 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3064 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3065 are set when Init Response is received.
3067 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3068 but returns diagnostic set as well.
3070 New function yaz_strerror which is a portable wrapper for
3071 strerror/strerror_r/GetLastMessage.
3073 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3074 is returned for MARC. If type is "oai", then OAI MARC is returned.
3076 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3079 --- 1.9.2 2002/11/26
3081 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3083 Fix bad race conditions on SIGTERM and terminate gracefully in
3086 Move retrieval (data1) module to Zebra since nobody seems to be
3089 Add GRS-1 render for ZOOM using same format as yaz-client.
3091 --- 1.9.1 2002/10/05
3093 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3095 Fix broken ESpec handling in data1 module.
3097 SGML reader parses comments and makes them part of the data1 tree.
3099 Added several type casts so that YAZ compiles as C++ code.
3101 ZOOM didn't handle PDU encoding failures properly.
3103 Added more Bib-1 diagnostics (approved extensions).
3105 GNU configure: better check for iconv.
3107 More portable use of accept, getpeername. Check for socklen_t. Use
3108 int/size_t if socklen_t is not defined.
3112 PQF parser rejects bad queries - including those with extra
3113 characters in them. PQF parser used to silently ignore that.
3114 Cleaner API for PQF added, which allows you to get detailed
3115 error information for bad queries (see yaz/pquery.h).
3117 Fixed bug in ZOOM_record_get for type "database".
3119 Implemented mini iconv library supporting conversions between
3120 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3122 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3124 --- 1.8.9 2002/08/20
3126 Fixed ZOOM C record cache so that preferredRecordSyntax and
3127 elementSetName is used to check for already fetched records.
3129 --- 1.8.8 2002/08/02
3131 Added three members in bend_initrequest structure to facilitate
3132 character set negotiation.
3134 Fixed a bug in frontend server that could cause indefinite
3135 loops under rare conditions.
3137 Revised character set utilities (charneg.h) so that encoding
3138 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3140 For PQF, directive @term <type> sets term type for Scan/Search.
3141 Here <type> is general, string, numeric, null. The term type
3142 is inherited - just like @attr.
3144 New call odr_set_charset that sets character set conversion for
3145 international-strings on a ODR stream. Prototype is:
3146 int odr_set_charset(ODR o, const char *to, const char *from);
3147 The InternationalString is still represented as C string in YAZ
3148 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3149 won't). On the protocol level, you can use any encoding.
3151 Support for UNIX sockets in ZOOM.
3153 Solaris recv sometimes returns errno == ENOENT. It is treated as
3154 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3156 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3157 both client and server. Code by Morten Bogeskov.
3159 --- 1.8.7 2002/05/22
3161 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3162 that they can be used directly from Visual Basic. You must recompile
3163 your windows APP if you're using ZOOM.
3165 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3166 Commands "lang" and "charset" sets language and character set respectively.
3167 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3168 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3170 Attributes from multiple CCL fields may be OR'ed rather than merged
3171 using directive "@field or". Fields are still merged by default -
3172 equivalent to "@field merge".
3174 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3177 Fixed bug in zget for parameter ExtendedServicesResponse.
3181 --- 1.8.6 2002/03/25
3183 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3185 Client displays USR.1:SearchResult-1 (hits per term).
3187 Additional Search Info for search in Generic Frontend Server.
3189 Fixed CCL parsing of "field=s".
3191 WIN32 installer - using the excellent NSIS software from nullsoft.
3193 Fixed CCL parsing of "field = - <number>".
3195 Added function yaz_marc_decode that decodes MARC for line mode
3196 display or XML (similar to that used by JZKit).
3198 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3199 Z39.50. But ISO/ILL was, however.
3201 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3202 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3204 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3205 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3207 --- 1.8.5 2002/02/03
3209 New YAZ client features: Command completion and new commands:
3210 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3211 Code provided by Jacob Poulsen.
3213 New call oid_trav, that visits all registered OIDs via callback.
3215 Function ZOOM_record_get now returns const char pointer rather than
3216 void pointer. It saves a lot of type casts.
3218 For YAZ client, command "auth" now allows you to set authentication
3219 in IdPass style. It is enabled when three tokens are given - order
3220 is user, group and password.
3222 Fix memory leaks in MARC record handling for ZOOM.
3224 New option for YAZ client, -k <kilobytes> that sets
3225 maximum record size. Similar to -k option for generic frontend
3226 server and yaz-ztest.
3228 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3230 Prefix query parser reports "fail" when bad attribute set is given.
3232 Fix in MARC decoder. Proximity logging. Fix for attribute set
3233 in scan handler for server. Patches by Shigeru Ishida.
3235 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3238 Configure option --with-openssl=<dir> now works when a directory is
3239 specified. Patch provided by Morten Bogeskov.
3241 New option for YAZ client, -u <auth>, that sets authentication.
3243 ZOOM fix: error information was sometimes "missing", since error
3244 was cleared/reset too when it shouldn't.
3246 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3248 --- 1.8.4 2002/01/04
3250 Scan for ZOOM API. New object ZOOM_scanset. New functions
3251 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3252 ZOOM_scanset_destroy.
3254 New ZOOM function, ZOOM_connection_last_event, that returns type
3255 of last event (such as "receive data", "send data", "apdu received",
3258 New ZOOM option, schema, that specifies schema for retrieval.
3260 New CCL feature. Qualifiers can be aliases for one or more
3261 other qualifiers (if more than one is given, OR is used).
3263 ZOOM uses named result sets if target supports it.
3265 Two new YAZ client commands: . (dot, which sources a script of YAZ
3266 client commands), and ! (to execute shell command.). Implemented
3269 Working on Debian packages.
3271 --- 1.8.3 2001/11/19
3273 YAZ client enables named result sets only if target supports it.
3275 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3277 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3278 with key="host" to get same result.
3280 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3281 Function Z3950_resultset_record(s) returns references to records
3282 "owned" by resultset. To become owner use Z3950_record_clone.
3284 Function z_ext_record handles Extended Services. Thanks to
3287 --- 1.8.2 2001/11/12
3289 CCL Parser fix: ignore token comma when dealing with and-lists.
3291 Documentation updates for COMSTACK.
3293 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3294 Changed prototype Z3950_records. For some functions, int parameters
3295 were changed to size_t.
3297 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3300 New MARC decode/display function, marc_display_exl, which properly rejects
3301 non-ISO2709 records. YAZ client uses it.
3303 --- 1.8.1 2001/10/29
3305 Fix bug: local attribute set wasn't set correctly in PQF strings.
3309 * Old Z39.50 codecs no longer supported.
3311 Added ZOOM C binding. See http://zoom.z3950.org/
3313 Renamed states for COMSTACKs to avoid confusion with events.
3315 Implemented cs_look and proper cs_rcvconnect.
3317 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3319 Configure detects POSIX threads on OpenBSD.
3321 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3322 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3324 When error is returned from present handler, non-surrogate diagnostic
3325 is returned in present response (and fetch handler is no longer called).
3327 * Minor adjustments to pquery parser (PQF). Token characters may be
3328 escaped by using backslash (C-style).
3330 PQF parser allows string attribute values to be specified. For @attr,
3331 non-numeric characters after the equal-sign are treated as strings
3332 (e.g. @attr 9=title).
3334 CCL trunction character may be defined (@truncation in file)
3336 * function zget_ExtendedServicesRequest sets waitAction to
3337 waitIfPossible (was wait).
3339 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3342 CCL operator names may be set in field definition files (CCL_bibset).
3343 See ccl/bib1 for an example.
3345 Fixes in ASN.1 compiler for C++ compatibility.
3347 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3348 and "op_or" to avoid conflict with C++.
3350 Fixed problem with GNU readline detection on Redhat 7.0.
3352 Added step-size for Scan backend handler.
3354 Fixed bug that made the frontend server crash when no attribute
3355 set was specified for scan.
3357 Front-end server automatically switches to original working directory
3358 when installed as an NT service. Previously -w had to be specified to
3361 Added extended attributes for retrieval module (data1), so that data1
3362 records carry d1_readXML/SGML attributes. d1_read also supports
3363 null-data rules ( <tag/>)
3365 On UNIX when POSIX threads are available, a separate library libyazthread
3366 is created. Programmers should link with that library and the yaz library
3367 when using threads. The reason for the split was that some applications
3368 on Linux, such as Apache, doesn't work well when using shared objects that
3371 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3372 (or any frontend server) in SSL mode by specifying ssl: followed by
3373 address. Only tested on UNIX.
3375 Added feature for CCL module. Virtual structure s=al or s=ol generates
3376 and-list and or-list respectively instead of phrase search.
3380 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3381 log_mask_str. This was done to avoid name conflicts with other libraries
3382 (such as other PHP extensions).
3384 Added raw OID member for preferred record syntax (request_format_raw)
3385 and returned record syntax (output_format_raw) for backend fetch method.
3387 Config file yaz-config now accepts options so that it returns specific
3388 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3390 Shared library support for UNIX using GNU libtool.
3392 * Modified backend interface. Request/Response struct's replaced by
3393 one read/write C struct. For example bend_fetchrequest and
3394 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3395 Every handler - even search has to be registered in bend_init
3396 handler. This means that the YAZ library no longer refers to
3397 external functions and it makes it possible to make the whole
3398 thing a single DLL/SO.
3400 Added Segment handler for backend server.
3402 Added Zmbol/Zebra administrative functions to YAZ client.
3404 Threaded frontend server on UNIX (when POSIX Threads are available).
3405 Starting the server with option -T enables multi-threading.
3409 Added configure option --enable-comp/disable-comp to control use
3410 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3411 located in sub directory asn.
3413 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3414 in ${exec_prefix}/bin along with the other programs yaz-client and
3417 GNU automake used to maintain makefiles.
3419 Added several OID's.
3421 Changed retrieval module so that we can load records with no abstract
3422 syntax defined. Tagpaths in these records are fully composed of string
3425 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3429 On UNIX, the generated makefile now supports a proper 'make install'.
3430 The prefix can be set via GNU configure to set the install location
3431 (default is /usr/local).
3433 * YAZ programs client and ztest were renamed to yaz-client and
3434 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3435 locations, such as /usr/bin,/usr/local/bin,etc.
3437 * YAZ Header files were moved from include to include/yaz. YAZ Header
3438 files are referred to as include <yaz/log.h> rather than <log.h>.
3439 The YAZ include path (-I ..) is therefore the same as before. Programmers
3440 should update their #include statements or use -Ipath/include/yaz
3441 instead. The main motivation for doing this change is that YAZ header files
3442 can be installed in "standard" locations /usr/include,/usr/local/include
3443 without introducing conflicts, since ALL YAZ header files are stored
3444 in subdirectory yaz (under /usr/include for example).
3446 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3447 rather than project/workspace files. We switched because project files
3448 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3451 Changed name of logging function, logf, to yaz_log, to prevent name
3452 clash with some math-log functions. The YAZ header log.h defines logf
3453 to yaz_log (#define) so there should be no incompatibilities by this
3456 Added bend_start/bend_stop handlers for server. These handler are
3457 called on start/stop of server. For windows they are called whenever
3458 a service is started/stopped.
3460 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3461 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3462 in util/yc.tcl. The auto-generated C code structures are, in a few
3463 cases, incompatible with the old decoders. There are differences in the
3464 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3465 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3466 The preprocessor variable ASN_COMPILED is defined when the compiled
3467 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3468 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3469 wish to use the old encoders/decoders you can specify --disable-yc
3472 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3473 version so that it supports both new - and old version of DB Update
3475 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3476 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3477 change. The name parameter can be set to 0 in which no name is specified
3478 for the construction. The macros odr_implicit and odr_explicit sets name
3479 parameter to zero for the construction involved. New macros
3480 odr_implicit_tag and odr_explicit_tag are similar to the others,
3481 except that a name parameter is added. For programmers' that don't use
3482 ODR they probably only need to change the call to z_APDU and z_External.
3484 Added access control facility by interfacing the TCP wrapper library.
3485 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3486 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3487 name of the daemon and enables the access control as specified in
3488 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3490 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3491 den Dool <H.M.vdnDool@kub.nl>.
3493 Added reference ID parameter to most functions in server API - refer
3494 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3496 Changed name of ccl library to libccl.a (was ccl.a).
3498 Fixed bug in decoder for Explain (Category TargetInfo).
3500 Added support for GNU readline in client. Thanks to Jacob Poulsen
3501 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3503 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3504 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3505 IMPLEMENTATION! This change was made to the development version before
3506 the ZIG decided to retract the amendment. If any users MUST be
3507 compatible with the original Update definition, PLEASE CONTACT US, and
3508 we will include a separate definition corresponding to the old Update
3509 ES. Note that because of the change to the ASN.1 of the
3510 TaskPackageRecordStructure we cannot define a single structure that
3511 will support both versions.
3513 * Added const modifier to buffer parameter for some ODR/BER encoding
3514 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3515 completeWAIS, odr_dumpBER.
3517 Fixed bug in client.c which caused a crash when a scanResponse didn't
3518 contain positionOfTerm.
3520 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3521 * will cause an error in a client if a non-YAZ target sends both a
3522 * list of Scan entries and non-surrogate diagnostics.
3524 Retrieval module enhancements. Tag sets may be typed in the reference
3525 to it. From the .abs-file the "tagset" directive takes a third optional
3526 integer type for the tag set referenced. From a .tag-file the "include"
3527 directive takes a third optional type as well. The old "type" directive
3528 in the tag set itself is still recognized but acts as the default type
3531 Backend interface change. Individual Scan terms returned from bend_scan
3532 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3533 in include/backend.h.
3535 Retrieval module enhancements. Multiple tag sets and attribute sets may
3536 be specified in abstract syntax specs. Revised the error/warning for
3537 logging messages reported by the retrieval module when reading the
3540 Object Identifier system (oid_..) changed. The API is backwards
3541 compatible but the oid-routines now allocates new OID's when needed.
3542 Raw OID's may be specified in oid_getvalbyname.
3544 YAZ now uses GNU configure to generate Makefile(s).
3546 * Minor changes in some of the member names of DeleteResultSetRequest and
3547 DeleteResultSetResponse. See include/proto.h.
3549 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3550 and added member 'languages' in TargetInfo (which was missing).
3552 Changed the way attribute sets are handled in the retrieval
3553 module. These are now cached, just like the abstract syntaxes
3556 Changed YAZ so that it links with compiled ASN.1.
3558 Added Explain-schema definitions and mapping routines. The following
3559 Explain categories have been implemented: AttributeDetails,
3560 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3562 Fixed minor bug in Windows version of Server Library.
3564 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3566 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3568 Added EXTERNAL: UNIverse Resource Report (non-standard).
3570 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3571 ENUMERATED and SET OF.
3573 * Added 'const' to some of the char pointer arguments for the
3574 functions, data1_read_node, data1_getelementbytagname,
3575 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3578 Fixed bug in data1_insert_taggeddata - the last_child member of
3579 parent wasn't initialised.
3581 * Changed data1_read_record and data1_read_node so that the supplied
3582 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3583 doesn't refer to any parts of the "SGML"-buffer.
3585 Fixed bug in server library (Windows version of statserv_remove).
3587 * Changed code so that it compiles as C++. The type definition
3588 of Odr_fun which is a member of Odr_arm was changed. The result is,
3589 that an explicit typecast is needed for the fun pointer when
3590 using Odr_arm - as in:
3591 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3593 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3595 Implemented the new structured date and time definition as approved
3596 by the ZIG. Added schemaId element to the specificTag in Espec-1
3597 (also approved at the last ZIG). Thanks to RVDM.
3599 Added some Object identifiers (RVDM).
3601 Changed the Update Extended Service (RVDM).
3603 Added command "refid" to client which specifies referenceId for
3604 the following requests.
3606 Implemented extended service handling for server. See ztest.c
3607 for an example as well as backend.h. New handlers are registerd
3608 in the Init handler.
3610 * Changed interface for sort in server.
3612 Added new members to statserv_options_block. It allows a server
3613 to read options from another source than just the command line. Thanks
3614 to Charles Woodfield.
3616 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3617 renamed to zboolean. Some C++ compilers complained about the name.
3619 Minor changes to gils.abs. Added index 's' (sort) on title
3620 and date/time-last-modified.
3622 --- 1.4pl2 1998/1/30
3624 Fixed bug in server library regarding inetd mode (-i). This bug
3625 was introduced by release 1.4.
3627 --- 1.4pl1 1998/1/29
3629 Added sort facility in client and backend server interface.
3631 Fixed problem with dependencies in Makefile(s).
3633 Fixed bugs for encoders/decoders of extended services and
3636 Implemented sub-tree feature for schemas. Sub-trees are
3637 referenced in *.abs-files. See explain.abs for an example
3638 of the use of this feature.
3640 Modified bib1.att; local attributes for ANY didn't include
3641 ANY itself (only affects use of the retrieval module).
3643 Fixed bug in plain SGML reader in function data1_read_node:
3644 tags with prefix "var" was incorrectly interpreted as variants.
3646 Added feature "sub-schemas" to enable references to - and definitions
3647 of - group of elements.
3649 * Removed member parent from type data1_element (in data1.h).
3651 Implemented function odr_nullval() that returns the value of
3654 * Removed member num_children from data1_node (in data1.h).
3656 Made NT service interface part of the server library. The
3657 function statserv_main uses the NT service when required and
3658 calls the statserv_start / statserv_close routines.
3660 Routine zget_SearchRequest and zget_PresentRequest fills
3661 resultSetName/Id member with "default" instead of "Default".
3663 Fixed memory leak in server. Request queue member wasn't freed.
3665 Fixed nmem_exit so that memory is freed.
3669 Revised the CCL parser utility to be thread safe.
3671 Added function, oid_ent_to_oid, to replace the function
3672 oid_getoidbyent, which is not thread safe.
3674 * Added nmem_init and nmem_exit to initialize and release
3675 NMEM resources. Function nmem_init should be called once in the
3676 initial thread before NMEM/ODR is used. statserv.c and client.c
3677 have been changed accordingly. The change was necessary to make
3678 NMEM thread safe. The NMEM memory pool is shared amongst threads
3679 in a process. Unix-based applications will still work fine without
3682 Added NT Services interface for the the Z39.50 (statserv) Server.
3683 Refer to the ztest.c source on the usage.
3685 Windows 95/NT port using MSVC5.0. Project files are included in the
3688 * Defined new 'global' handle for the retrieval (data1) system. The
3689 new handled, data1_handle, describes the state of the data1 system.
3690 This handle is passed as first argument to virtually all
3691 data1 related routines. The functions data1_create and data1_destroy
3692 creates and destroys a data1 handle respectively.
3694 Added ODR encode stream member to all backend request structures
3695 init, search, scan etc. This stream should be used to allocate all
3696 memory used for the response when thread safe operation is needed.
3698 Changed the comstack utility, cs_addstr, to be thread safe. The
3699 returned hostname string returned by the function is now part the
3702 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3703 function. The cs_straddr takes a COMSTACK handle as argument, so this
3704 function must be used after cs_create and before bind/connect.
3705 This function is thread safe.
3707 Moved test server to 'ztest' directory - generic server code still
3708 in 'server' directory.
3710 Made prefix query (pquery.c) utility thread safe.
3712 Added new function modifier YAZ_EXPORT to 'export' public DLL
3713 functions when using windows (see include/yconfig.h).
3715 Added definitions to the OID database (util/oid.c) (RVDM).
3717 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3719 Added call to ccl_rpn_delete in client program.
3721 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3722 release of RPN structure.
3724 Added support for C++, headers uses extern "C" for public definitions.
3725 With input from RVDM.
3727 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3728 Thanks to Ronald van der Meer (RVDM).
3730 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3732 Added support for private extensions to the OID database
3733 (oid_setprivateoids()). Thanks to RVDM.
3735 Added optional, physical ANY (key replication)
3737 Fixed null-reference problem in GRS-1 output filter.
3739 Proximity operator added to Prefix Query Format (PQF).
3741 In test client command "base" accepts multiple databases.
3743 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3747 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3749 Smallish bug-fixes in the new encoders/decoders (explain).
3751 Bug fixed in DeleteRequest.
3753 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3755 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3757 Added SOIF syntax (using private OID for now) to retrieval module and client.
3759 Added Update extended service.
3761 Added SearchResult-1 additional info structure.
3763 Added optional CCL (ISO8777) interpreter as separate module. Available
3766 --- 1.2 1996/6/10 (1st anniversary release)
3768 Added Summary record syntax. Lightly tested.
3770 Added OPAC record syntax. Untested.
3772 Added ResourceReport service encoders/decoders. Untested.
3774 Fixed bug in z_Unit - wrong tagging on unitSystem.
3776 Fixed bug in the DiagRecs decoder.
3778 Added options for max PDU size and session timeout to frontend-server.
3780 Added documentation of query-language parsers and other supporting utilities.
3782 [frontend-server] Added Attribute set to the bend_scanrequest API.
3784 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3785 surrogate diagnostics were generated.
3787 [retrieval] Allow multiple local values for attribute.
3789 [retrieval] Allow multiple attributes per element in .abs files. index type.
3791 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3793 --- 1.1pl2 1996/4/10
3795 Minor changes, mostly specific to Zebra's requirements (retrieval)
3799 Repaired bug in frontend server when running multiple listening
3800 endpoints in dynamic mode.
3802 z_External() now won't break if a known, ASN.1 value comes encapsulated
3803 in an octet-string. The value will pass through unmodified in an Odr_oct.
3805 Added a bit of code to the demo client to decode & display
3806 ASN.1-structured records represented in the octet-aligned branch of
3807 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3809 Added z_ext_getentbyref() to the ASN module. Doc updated.
3811 * Completed the SCAN definition in the ASN module. This may break SCAN
3812 code based on older YAZ-versions at compile-time. The fix is easy -
3815 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3816 under the SCAN definition. Remember to initialize this, server-people.
3818 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3819 that this does not extend to ODR and ASN.
3821 Comstack allows insertion of established socket (primarily for
3822 inetd-operation of servers). Doc updated.
3824 Front-end server can now start from the inetd in TCP mode. Doc
3827 --- 1.0pl4 1996/1/24
3831 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3832 the rank and record number.
3834 Adjustments to the frontend server.
3836 Fixed diagnostic BER dumper. It ignored the file argument.
3840 Various changes to retrieval module.
3842 Changed the union discriminators of the protocol files from enums to
3843 ints paired with #defines.
3845 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3848 *Changed operator in the RPN structure to 'roperator', again to avoid a
3851 Fixed problems in Explain decoders/encoders.
3853 --- 1.0pl2 1995/12/6
3855 Memory bug in log module fixed.
3857 --- 1.0pl1 1995/12/5
3859 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3861 Bug in Explain DatabaseInfo module fixed.
3863 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3867 The shift to v1.0 signals that we now consider the *core* functionality
3868 of YAZ reasonably stable (the core being more or less equivalent to
3869 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3870 tested (Explain not at all - though that will happen soonish).
3872 Minor changes to code to support Windows port.
3874 Various minor changes after we're getting to use GRS-1 & co. more.
3876 Added Espec-1 format.
3878 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3879 of the protocol and it cannot be selected when encoding (maps into 'string'
3880 when decoding). Needed to talk to some servers.
3882 Demo client can request simple element set names.
3884 Added Diagnostic Format encoders/decoders.
3886 Added simple Close handling to frontend server (no hooks for resource
3887 reporting yet), and demonstration client.
3889 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3891 --- 1.0b3 1995/08/24
3893 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3894 handled incorrectly when records were requested in the searchResponse. This
3895 will only affect you if you use the frontend-server.
3897 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3898 Test-client will ask for and print GRS1. Ztest will return dummy records
3901 Added Explain encoders/decoders to the service-level API. Untested.
3903 Added Extended Services: Item Order encoders and decoders to the Service-
3904 level API. Untested. We could use a recent copy of the pertinent bits
3905 of the ILL protocol to add those bits.
3907 Added diagnostic format 1 encoders/decoders to the service-level API.
3910 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3911 odr_cons.c, which causes a more correct output.
3913 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3914 was always set to 0 when no records were requested in the searchRequest.
3916 * Added better external-handling. This shouldn't harm old code that
3917 *encodes* externals. It can break code that looks for a
3918 'single-ASN1-type' representation, since those types that are known
3919 are now decoded immediately. Look at the SUTRS sample code in
3920 seshigh.c and client.c. Documentation updated.
3922 Handling of structured records in bend_fetchresponse. Length -1 marks
3923 structured record, type is deduced from format field.
3925 --- 1.0b2 1995/06/27
3926 Fairly quick maintenance release to add SUTRS support.
3928 Fixed handling of SUTRS records in the demonstration client.
3930 * Added format field to the bend_fetchrequest and bend_fetchresponce
3931 structures of the backend API (frontend server). When the record is
3932 returned, the value of the format field is mapped to an OID. The
3933 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3934 of the record. The special value VAL_NONE in the bend_request means
3935 that no specific format was requested by the client. Documentation
3936 updated accordingly. Test server (ztest) will return a fixed dummy
3937 SUTRS record if your client requests SUTRS.
3939 Documentation updated accordingly.
3941 You can now set external libraries and RANLIB support in the top-level
3945 First public release.
