3 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
5 wrbuf_cstr: make it thread safe YAZ-753
7 yaz_log_init_file may take fd=<no> to open log file at the FD given.
11 Offer new utility function zget_AttributeList_use_string.
13 New conversion step, solrmarc, for record conversion module.
17 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
18 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
23 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
24 The standalone ZOOM sort was completely broken since 5.0.13.
26 ZOOM: generate event Connect rather than None for partial connect
27 (in fact getaddrinfo resolving).
29 ZOOM: only supply clientIP for InitRequest. Rather than for all
32 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
34 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
35 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
36 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
38 New "Facets" section in the documentation.
42 Call exsltRegisterAll in yaz_init_globals, so that all applications
43 using YAZ will have EXSLT things enabled.
45 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
47 Update various URLs to the re-organized SRU pages at LoC.
51 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
54 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
55 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
56 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
61 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
65 Fix gcrypt not properly initialized YAZ-740.
69 Describe memcached option for ZOOM.
71 ZOOM: throw present request out of range again YAZ-739
72 Was removed in YAZ 5.0.13.
76 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
77 with localtime_r when threads + fork is used (such as Metaproxy).
79 yaz-config: quote some RHS values (that might include blanks)
81 zoomsh: shows SearchResult-1
83 zoomsh: sortby command
85 zoomsh: use proper list of connections and result sets YAZ-725
87 Avoid yaz_log in sigterm handler for GFS YAZ-737
88 Logging is still performed, but outside sig handler.
90 New ZOOM C feature: result-set caching with memcached. Example:
91 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
93 Remove SSL via OpenSSL support YAZ-732
94 Also deprecate two functions from comstack that aren't working with
95 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
97 Revert "Bison: use %name-prefix directive rather than -p option"
101 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
103 SRU GET/Solr base URLs may hold additional ?args YAZ-729
104 ZOOM option extraArgs already does this, though. It seems useful
105 when dealing with Solr targets to limit by filter, eg.
106 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
108 Remove #fragment for HTTP request encoding YAZ-730
110 Doc: Update list of DLLs/LIBs
112 Doc: update href link to Unix utils and Git.
114 --- 5.0.11 2014/01/15
116 ZOOM: fix "lost connection" problem with servers that uses both squid
117 and another proxy behind it that returns Location headers with relative
120 zoomsh: do not use readline for stdin (no tty) YAZ-724
121 Just use fgets in that case. If the user hits Ctrl-D a new-line
124 zoomsh: empty command ignored YAZ-723
125 rather than performing exit of zoomsh.
127 yaz-url utility offers option -v to enable verbose mode.
129 yaz_url uses yaz_check_location and offers verbose mode.
131 Add new function yaz_check_location.
132 This function gets an absolute URI from Location (HTTP redirect).
134 cookie API: introduce yaz_cookies_reset
136 Update cql.y for newer bison YAZ-720
137 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
138 longer supported. Instead one must use %lex-param and %parse-param .
140 --- 5.0.10 2014/01/09
142 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
145 rpn2solr: support truncation left(2), left&right(3) YAZ-718
147 Mention SRU version 2.0 in yaz-client man page.
151 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
156 Make cs_parse_host public.A
158 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
159 introduced in YAZ 5.0.6.
163 Fix buffer corruption for yaz-ztest record fetch.
167 Allow yaz-ztest to return user-defined records (one record per file).
168 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
170 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
171 Use the stream write instead of odr_printf which has a 4K tmp buffer.
173 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
177 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
178 can read and write this format. For record format JSON, yaz-ztest returns
179 MARC-in-JSON records.
181 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
182 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
186 Improve error reporting for ICU chains YAZ-707
187 Report config element+rule when ICU status is "failure".
189 ZOOM: stop fetching if present response has no records YAZ-710
190 Some targets return less records than their hit count would suggest.
191 This prevents ZOOM from continuing to fetch records if any present
192 response has 0 records in the response.
194 Ensure that GFS calls exit if any listener fails YAZ-710
195 Before, if XML config was in use, it would start the default
200 yaz-ztest: -V shows version (like yaz-client -V)
202 New iconv encoding: danmarc YAZ-692
204 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
206 daemon: only wait for immediate child rather than all children. YAZ-704
208 yaz-client: fix setting of SRU record schema. If scheme was unset, it
209 could lead to invalid memory reference.
213 yaz-ztest returns schema for MARCXML test records. SRU require that
214 recordSchema for records.
216 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
217 instead of non-surrogate diagnostic. This is a per-record failure.
219 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
220 may refer to multiple listeners now. Attribute listenref is a comma separated
223 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
224 option is given for GFS, the dirname of filename (for -f) is used
225 as prefix for options such as cql2rpn, ccl2rpn, etc.
227 Content-Type charset fixes YAZ-701 . Do not inspect charset in
228 Content-Type header for SOAP when decoding SRU. The payload (XML)
229 itself tells what encoding it is. In response, never supply encoding
230 in Content-Type. The response payload (XML) tells what it is (with no
231 encoding in XML it's UTF-8).
233 HTTP decoding: allow blanks in URL paths YAZ-700
237 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
238 and facets. Ensure recordData and recordSchema are always present in
239 record element, because they are required.
241 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
244 Simplify in a lot of places using odr_strdupn.
246 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
250 Increase various buffers in GFS's statserv_options_block
251 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
252 This change makes many type-casts redundant, and, thus simplifies code.
254 Remove last bits of WAIS support.
256 Remove member 'size' from Odr_oct.
258 Slim down the public part of 'struct odr'. Most elements are not part
259 of struct Odr_private.
261 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
262 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
263 In particular facets are supported in both client - and server side.
264 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
265 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
266 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
267 both request/response). This is what a search handler in the GFS
268 will see (regardless of whether operating in SRU mode or Z39.50).
270 Changes to the srw.h (SRU/Solr) definitions include:
271 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
272 (char*), which replace union query and query_type (int). This is because
273 SRU 2.0 supports a queryType parameter. This also means that, to carry
274 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
275 x-pquery=PQFstring (extention parameter). The extension parameter
277 - New element, packing, that has information about SRU
278 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
280 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
282 New element, packing, in Z_SRW_explainRequest.
284 New elements in Z_SRW_scanRequest, queryType and scanClause.
285 These replace query_type and scanClase untion. This is similar to what
288 --- 4.2.69 2013/10/01
290 GFS: log when closing down - at least SIGTERM YAZ-684
291 Also change formatting WRT PID logging a bit.
293 Improve display of MARC records with multi-byte subfield IDs YAZ-695
294 In some rare cases subfield identifiers are multi-byte characters.
295 This will try to deterime length of those and split accordingly.
296 This affects display in line mode as MARCXML/MarcXchange. The encoding
297 of ISO2709 is the same.
299 Change inp argument to const for yaz_read_UTF8_char.
301 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
303 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
305 Better check of marc leader info YAZ-691
306 Problem is that some systems generate MARCXML/MarcXchange with
307 funny headers. These will not work if encoded as ISO2709.
308 Some tests produce new output, due to updated warning messages
310 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
312 yaz-client: display MAB records YAZ-689.
313 Thanks for Heiko Jansen for this patch.
315 New utility z_get_HTTP_Response_server which allows both HTTP server name
316 and HTTP server URL to be given in response.
318 Debian: do not depend on obs tcl8.3.
320 Debian: do not depend on obs libicu36-dev.
322 --- 4.2.68 2013/09/23
324 GFS: pass additionalSearchInfo to search memeber search_input if
325 given. Otherwise pass otherInfo. Request for facets and other search
326 related things will be passed there in future versions of YAZ.
328 New ZOOM setting, authenticationMode, which allows authentication
329 paramters to be encoded in the URL rather than via HTTP Basic auth.
332 rpn2solr: fix nested AND/OR handling. YAZ-685
334 Add comparison routines for some Z-types, such as NamePlusRecord,
335 RPNQuery, Query, RecordComposition and OtherInformation.
337 --- 4.2.67 2013/09/19
339 Don't decode MAB as MARC. Just like we don't attempt to decode
340 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
342 CCL: allow quoted terms for date ranges. YAZ-681
344 Introduce ccl_parser_qual_search. This function makes old function
345 ccl_qual_search, from YAZ 2, available again.
347 Add yaz_facet_list_to_wrbuf. YAZ-683
349 --- 4.2.66 2013/09/11
351 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
352 schema was given for search. YAZ-675
354 Add Solr date range searches. YAZ-621
356 --- 4.2.65 2013/08/22
358 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
360 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
362 ISO2709/MARC parse most octet aligned records; not just those that
363 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
364 MARC parse more records instead of just dumping as is. YAZ-670
366 ZOOM: proper caching for variations of record schema. YAZ-671
368 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
370 --- 4.2.63 2013/07/17
374 --- 4.2.62 2013/07/11
376 New utility z_get_HTTP_Response_details - an extended version of
379 New utility yaz_url_get_error which returns error message of last
380 failed yaz_url_exec call.
382 yaz-url and url functions: allow max HTTP redirects to be controlled.
384 New functions yaz_file_glob2, yaz_xml_include_glob.
385 These functions takes a flags parameter, which, for now only controls
386 whether to fail inclusion of a non-existing file (without glob
387 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
389 --- 4.2.61 2013/06/20
391 For MARC XML parsing, allow record without leader. A fake/default leader
392 is inserted and a warning is tagged with the record.
394 ICU: fix leak in in icu_iter_get_org_info.
396 --- 4.2.60 2013/06/14
398 ICU: fix bug in icu_iter_get_org_info (un-init variable).
400 --- 4.2.59 2013/06/11
402 Implement z_HTTP_header_remove.
404 --- 4.2.58 2013/06/11
406 ICU: Disallow 0 ptrs for some ICU string utilities.
408 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
409 returns original tokens (before normalization).
411 CCL: avoid z39.58/regex truncation when not needed. Apply only the
412 conversion of those masks, when absolutely necessary.
414 CCL: configurable masking character - @mask. Default masking character
417 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
418 full response anyway, so a Transfer-Encoding header will obstruct the
421 --- 4.2.57 2013/05/15
423 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
424 picking a socket. Problem is that some systems has IPV6 support, but
425 we can't create sockets for them, so we pick AF_UNSPEC first.
427 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
428 use content_len to determine resulting Content-Length in HTTP response
429 and NOT Content-Length supplied in headers by user.
431 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
432 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
434 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
437 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
438 with big endian and unsigned char (by default).
440 --- 4.2.56 2013/04/26
442 Fix yaz-client connect (crash in 4.2.55).
444 --- 4.2.55 2013/04/26
446 Fix proxy/host problem for ZOOM that could occur if unix sockets
449 New Debian package libyaz4-dbg.
451 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
452 differently in tcpip_close.
454 --- 4.2.54 2013/04/17
456 Windows installer of YAZ includes YAZ4J as a component.
458 CQL: allow "extra terms" again, by default. Thus, the CQL parser
459 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
460 and earlier. CQL parser may operate in strict mode where queries
461 not conforming to the standard BNF are rejected (syntax error).
462 Whether the CQL parser operates in strict mode is controlled with
463 cql_parser_strict . Strict mode enabled with option -S for utilities
464 cql2pqf and cql2xcql .
466 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
468 --- 4.2.53 2013/04/10
470 New charset, MARC-8c, which is like MARC-8 but allows control characters
471 0x01 through 0x1F, except ESC to be passed through verbatim.
473 Fix a problem with duplicate sub field character in MARC output. Problem
474 happened only when output was MARC-8 encoded.
476 --- 4.2.52 2013/04/03
478 yaz-ztest: Use hash for fake hit count. Before, random number was used.
479 This is problematic for unit tests using yaz-ztest. This patch also makes
480 a hash for CQL queries. For RPN, any term with a leading digit will be
481 treated as pseudu hit count (to force any particular hit count by a client).
483 yaz-ztest: return unique MARC dummy records. Beyond record offset
484 24, the author surname is patched with offset to make all records
487 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
488 on system wide default (/proc/sys/net/ipv6/bindv6only).
489 @4 binds to IPV4 only. @6 binds to IPV6 only.
491 Update CQL API documentation a bit
493 CQL: don't accept extra terms for queries. Makes the CQL parser
494 stricly conformant to the standard.
496 --- 4.2.51 2013/02/12
498 GFS: scan handler gets extra_args from request and may return extra
499 response data . That's for SRU only.
501 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
503 --- 4.2.50 2013/01/30
505 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
507 OPACXML: sync spelling of availabilityDate in XML to that of Schema
508 opaxxml.xsd. The schema had the correct spelling of this member always.
509 The ASN.1 was mis-spelled and still is (API change) - we are
510 not changing this. However, the OPAC to XML conversion had yet
513 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
516 New function, z_ext_record_oid_nmem, which is similar to
517 z_ext_record_oid but takes NMEM rather than ODR
519 --- 4.2.49 2013/01/18
521 ICU: New conversion element 'join' which joins tokens into one
522 with a custom character given by rule attribute.
524 --- 4.2.48 2013/01/10
526 New GFS search member: present_number. This is a hint to the
527 search handler how many records are going to be fetched immediately
528 following search. There's no guarantee that it's going to be the case,
529 since it depends on hit count (for Z39.50 piggyback) and whether errors
532 Make a few functions static (private). The functions getbyte_stream,
533 ungetbyte_stream and yaz_gets are now private. They were never declared
536 yaz-marcdump: exit(5) for serious decoding errors
538 ISO2709 decoding: be more picky WRT header
540 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
541 was only used as to indicate that next-result-set-position should be
543 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
544 Based on patch from Ashley Sanders.
546 Make some functions static/private in PQF parsing. Those functions were
547 never declared in a public header and so should not be in use by
548 applications based on YAZ.
550 --- 4.2.47 2012/11/23
552 ZOOM: special options to control APDU logging.
553 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
554 logging of APDUs until "saveAPDU" option is set again. If logging is
555 already enabled the effect is that current APDU buffer is cleared.
556 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
557 logging (default behavior on new connection).
558 The APDUs sent/received can be obtained by using
559 Using ZOOM_connection_option_get(c, "APDU") or
560 ZOOM_connection_option_getl(c, "APDU", &l).
562 GFS: relay implementation_version from backend
563 From 3.0.40 and later, implementation_version from backend was
564 not used in init response at all.
566 --- 4.2.46 2012/11/15
568 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
569 mode at all. Probably never did.
571 Make a new version of ztest.pem that, at least, is not expired.
573 --- 4.2.45 2012/11/13
575 Fix description of CCL directive 'case'.
577 More tight checking of form arguments (yaz_uri_to_array). Makes
578 YAZ better at rejecting big and/or bad POSTs.
580 SRU decoding does not report more than up to 10 invalid arguments.
582 rpn2cql: less quotes in generated terms. Semantics unchanged, but
583 it's prettier this way.
585 --- 4.2.44 2012/10/25
587 New utility yaz_decode_init_diag. Defined in proto.h.
589 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
590 given for unix local socket.
591 The COMSTACK string for doing so is:
594 unix:/myfile:tcp:localhost:9999/mybase
595 unix:/myfile:localhost:9999/mybase
596 unix:/myfile:http://fakehost/mybase
598 debian: Use dpkg-buildflags in build process.
600 --- 4.2.43 2012/10/19
602 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
603 global's SRU service uses a recordPosition scheme starting from zero.
604 First record's position should be one
605 according to the standard.
607 --- 4.2.42 2012/10/18
609 Allow more namespaces for SRU. This is to allow, for example, an
610 incorrect namespace returned from server
611 http://services.igi-global.com/sru .
613 Minor fixes for compilation on Windows.
615 --- 4.2.41 2012/10/11
617 daemon: log total number of bad signals from child on stop so that it
618 is more easy to spot problems with child worker processes.
620 retrieval: empty backend name attribute omits element set
621 from being used in retrieval.
623 --- 4.2.40 2012/10/04
625 Implement Solr sort strategy "solr", similar to sru11 sorting.
626 This will implement the correct parameters on Solr requst to do
629 --- 4.2.39 2012/09/28
631 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
634 MARC: Extra/missing indicator handled for MARCXML.
635 The indicator length is given in header and is the same for the
636 whole record. If attributes ind1, ind2 are missing, then content
637 character defaults to blank. Extra indicator attributes (beyond)
638 indicator length are treated as an error.
640 Reformat: delete trailing whitespace
642 --- 4.2.38 2012/09/17
644 MARC: fix non-ASCII characters for leader. This is to ensure we can
645 generate XML in UTF-8.
647 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
648 in one node with structure word.
650 --- 4.2.37 2012/09/04
652 yaz-json-parse: JSON output may be pretty printed by using option
655 Increase default value of max message for Z39.50 Init for GFS, ZOOM
656 and yaz-client. Old value was 1 MB. New value is 64 MB.
658 --- 4.2.36 2012/08/22
660 yaz-client: don't display bogus records from SRU servers. Some SRU servers
661 return more records than given by *maximumRecords*. Skipping those in
664 record_render: simplify buffer return handling and fix at least one bad
665 memory reference, that broke the test_embed_record sometimes.
667 Allow http://user:pass@host notation for yaz_url_exec.
669 zoomsh: allow shell command to be executed. Via the system(3) call.
671 yaz_poll: Allow num_fds == 0
673 yaz-client: fix bad encoding of "itemorder item". The itemorder
674 item <no> - command forgot to use length of encoded Item Request
675 package. Error present since YAZ 3.
677 yaz-ztest: fix bad usage of session handle. Bug was introduced when
678 result sets were saved (271a9c83).
680 SRU recordPacking: guess record packing in response rather than looking
681 at the recordPacking element which, OF COURSE, changed semantics in SRU
684 Decode SRU 2.0 responses. The official namespace for responses, according
685 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
686 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
687 nature.com's server, however, usee namespace
688 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
689 we are now using a glob-expr to match up the namespace. ZOOM C and
690 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
691 I can not find a single real example showing the "real" namespace in
692 the documentation from OASIS. The namespace for requests is different
693 from responses, but this is not added to YAZ yet, when we don't encode
696 --- 4.2.35 2012/06/26
698 zoom/record_render: add support for Base64 decoding fo MARC records
699 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
700 which will decode base64 + ISO2709 marc-8 encoded material from text node
703 --- 4.2.34 2012/06/07
705 Add missing definitions ZOOM_resultset_get_facet_field_by_index
706 and ZOOM_resultset_facets_names.
708 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
711 Change APDU dump printing to avoid long leading blanks. For levels 16
712 or larger the level is shown and the indentation is truncated but
713 recursed with modula 8. This makes it still reasonable easy to read
714 - even for nested BER dumps.
716 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
717 return 0 (incomplete package) in case where the BER package was
718 considered too nested (return value of -2).
720 dumpber: lines of level 15 are not indented further. Two spaces per
721 indentation; indentation 15 or more is indented to a fixed indentation
722 and augmented with a level=<no> indication.
724 zoomsh: increase max size of command+args
726 GFS: No limit in RPN buf size in CQL to RPN conversion.
728 --- 4.2.33 2012/05/09
730 New function for daemon utility, yaz_daemon_stop .
732 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
734 --- 4.2.32 2012/04/25
736 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
737 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
739 --- 4.2.31 2012/04/23
741 YAZ daemon utility relays SIGUSR1 to child process.
743 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
744 would result in en empty database list - which in turn would result in
745 encoding failure for search.
747 Fix reading beyond string in yaz_sort_spec.
749 --- 4.2.30 2012/04/11
751 Add two new SRU diagnostics:
752 236: Access to specified database denied
753 1015: Init/AC: Maximum number of simultaneous sessions for Userid
755 Document the very useful ZOOM-C option "apdulog".
757 CQL to RPN: term may be passed through verbatim. This is enabled with
758 truncation.cql . The assumption being that the term is already CQL.
760 --- 4.2.29 2012/03/20
762 record_conv: leader spec may be given for marc element.
763 The leader spec is given as attribute leaderspec for element marc.
764 For example to convert a MARC21 record from MARC-8 to UTF-8:
765 <marc inputformat="marc" outputformat="marc"
766 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
768 record_conv: allow user-XSLT params. For example:
769 <xslt stylesheet="MARC21slim2DC.xsl">
770 <param name="myparameter" value="myvalue"/>
771 <param name="otherparameter" value="othervalue"/>
774 record_conv: fix error handling for missing marc charsets.
776 CQL: fix extra terms in wrong order.
778 --- 4.2.28 2012/03/06
780 record_conv: modify new API for conversion types. The conversion types
781 may be passed in new functions yaz_record_conv_configure_t and
782 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
784 Avoid mixed statement/variable declare; fixes compilation with Visual
787 --- 4.2.27 2012/02/28
789 Add non-standard SRU diagnostic: 235: "Database does not exist".
790 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
791 Update SRU to Bib-1 diagnostic maps accordingly.
793 CCL: add two new diagnostics for unsupported masking. The new
794 diagnostics are: "Embedded truncation not supported" and
795 "Single charcacter mask not supported".
797 --- 4.2.26 2012/02/23
799 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
801 --- 4.2.25 2012/01/11
803 Build YAZ for Ubuntu Oneiric.
805 CCL: allow parantheses for proximity operands. For example CCL query
806 (a) % (b) is now allowed.
808 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
809 marked dead, rather then being destroyed. If not, the session memory is
810 being free'd before the search/scan handler is finished. Also destroy
811 'request' memory in request_release rather than in various places,
812 which resulted in leaks from time to time.
814 --- 4.2.24 2011/12/21
816 cql_sortby_to_sortkeys: honor sort prefix.
818 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
819 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
820 The rpn2cql family of functions now always returns quoted CQL terms.
822 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
824 --- 4.2.23 2011/12/15
826 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
827 sequence is treated as one. For example, &&a=b&&&c& is identical to
830 --- 4.2.22 2011/12/05
832 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
833 APDUs for a connection to a WRBUF.
835 --- 4.2.21 2011/11/23
837 Fix cql_sortby_to_sortkeys. Completely broken before.
839 Make CCL's @truncation work again.
841 --- 4.2.20 2011/11/09
843 New ZOOM connection setting: tproxy. It's like proxy, but does not
844 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
845 to set resolved address + port for a connection outside ZOOM itself.
847 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
849 --- 4.2.19 2011/11/07
851 Fix uninitialized variable in Solr spell support (could cause SEGV
852 for SRU response decoding).
854 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
855 back-end's addinfo through into the ZOOM response addinfo.
857 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
858 they are separated by a colon and a space rather than simply
861 --- 4.2.18 2011/10/28
863 Add support for Solr spell-checking/suggestions through ZOOM.
864 If a Solr target has been configured correctly for spelling-checking
865 and suggestions, these will now be returned on the ResultSet option
866 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
868 --- 4.2.17 2011/09/28
870 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
871 with a flag whether to substitute escape sequences or not.
873 --- 4.2.16 2011/09/22
875 Fix nmem_strsplit_escape to substitute escape char properly.
877 New option for zoomsh -e , which makes it abort on first error and
878 return process exit code to indicate success/failure.
880 YAZ options utility supports special option -- which makes all it treat
881 all following arguments as non-options.
883 --- 4.2.15 2011/09/16
885 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
886 searched if absolute filename is given.
888 Fix conv_xslt() error-reporting when stylesheet is not found.
889 (The value of fullpath is meaningless in this situation.)
891 --- 4.2.14 2011/09/07
893 Fix problem in CQL sort node creation: un-initialized memory.
895 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
896 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
897 CQL sortby depending on whether Type-1 or CQL is actually sent to the
900 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
901 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
903 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
904 will make it possible to use both single-character mask (#) and wildcard (?)
905 in CCL . Throw diagnostic for left truncation because that is not supported
908 --- 4.2.13 2011/09/01
910 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
911 cases using escapes (\-sequences) and masking.
913 PQF parse fix: A trailing backslash followed by end-of-string (\0)
914 would result in a read one byte beyond string.
916 rpn2ccl may use Z39.50 masking for terms (t=z).
918 ICU check fix. Don't include library -lCrun on Solaris, unless present.
920 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
921 not --cppflags (which seeems like an error in icu-config).
923 --- 4.2.12 2011/08/27 RPM package only
925 cql2ccl: fix conversion of terms: operator characters were not
928 --- 4.2.11 2011/08/25 RPM package only
930 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
931 CCL parser will map both # and ? to their regular expression
932 quivalents (. and .*).
934 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
935 of reserved CQL characters.
937 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
938 is, so that they are passed through.
940 --- 4.2.10 2011/08/24
942 ZOOM SRU mode: more aggressive re-connect.
944 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
945 made available as a utility function, declared in <yaz/logrpn.h>
947 rpn2cql_structure() supports proximity nodes (except that the Type-1
948 proximity node's "exclusion" binary is ignored, as there is no way to
949 express that in CQL). Fixes bug #4564.
953 Fix SEGV that could occur if set command of zoomsh was given without
954 value (2nd argument).
956 Fix SEGV that could occur if unsupported transport was given for
957 COMSTACK - say https (when SSL was unavailable).
959 Build yaz-url on Windows too.
963 New utility to get web content. Header is url.h. A command line tool
964 yaz-url is part of the distribution and packages.
966 Fixes for SSL COMSTACK (when gnutls is in use).
968 New functions yaz_base64{encode,decode}. Header is base64.h.
972 ZOOM C includes HTTP response buffer as additional info if it fails
973 to decode the SRU response.
975 Make wrbuf_json_puts available.
979 zoom: throw diagnostic for invalid value for option "sru". Before a
980 bad SRU request was sent.
982 Adding new utility wrbuf_vp_puts.
984 Add cclxmlconfig.obj to win/makefile. It was missing completely.
988 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
989 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
990 redirect was used at the same time.
992 MARC line mode decoding: be less picky about length given - first
993 5 digits of header that is.
995 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
997 Changes to decoding of SRU records: a record with recordPacking=xml is
998 modified with a new root element <yaz_record> if the recordData contains
999 multiple children elements. This is to make the record XML parseable
1002 RPN to Solr conversion: encode special characters.
1004 Generic Frontend Server: fix uinitialized member, stepSize.
1006 --- 4.2.4 2011/06/21
1008 Fix a bug in SRU decoding of records.. The database records stored
1009 had un-initialized memory, but it would only be seen with yaz_record_render
1010 and type_spec="ext" .
1012 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1014 --- 4.2.3 2011/06/17
1016 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1018 --- 4.2.2 2011/06/10
1020 Add new utilities to convert from CQL to CCL . These utilities have
1021 prefix cql_to_ccl defined in cql.h.
1023 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1024 lead to memory heap corruptions when ICU utilities were in use.
1026 --- 4.2.1 2011/06/07
1028 Make compilation work without Libxml2.
1030 yaz-client: remove redundant blanks in display of searchResult-1 term
1033 --- 4.2.0 2011/05/18
1035 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1036 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1038 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1039 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1040 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1041 Note that the CQL sortby spec is only converted when the GFS is already
1042 converting from CQL to RPN (cql2rpn element).
1044 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1045 specify whether to collapse delimitors or not. The existing nmem_strsplit
1046 do collapse (collapse parameter = 1).
1048 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1050 Rename internal func yaz_use_attribute_create. While non-static, this
1051 function is not declared in a public header.
1053 --- 4.1.7 2011/03/15
1055 Add -lCrun when linking with ICU on Solaris.
1057 More quicks character set conversions for OPAC records.
1059 --- 4.1.6 2011/03/10
1061 fix problem with record_render: records were converted (character set
1062 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1064 --- 4.1.5 2011/03/08
1066 SRU: add methods for handling DADS SRU-proxy facets.
1068 Separate OPAC record character set for ZOOM_record. yaz_record_render
1069 allows a character set given as charset=from/opacfrom,to where 'from' is
1070 the character set of a bibliographic record, 'opacfrom' is character set
1071 of OPAC record and 'to' is the target character set.
1073 --- 4.1.4 2011/02/21
1075 yaz-client: show may XML format records. Command show followed by 'format'
1076 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1079 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1082 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1084 --- 4.1.3 2011/01/27
1085 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1087 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1088 this package can be distinguished from other vendors.
1090 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1091 as determined by configure
1093 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1095 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1096 returns no error and no record, the present request is considered
1097 partial (only a subset of the records could be returned by backend), and
1098 so it is appropriate to set Present Status to partial-4.
1100 --- 4.1.2 2010/11/02
1102 Move yaz-config man pages to section 1.
1104 More documentation about Solr.
1106 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1107 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1108 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1109 peers on some Linux systems. However, in general that does not work
1110 so YAZ can not rely on that to work. Debian changed behavior in this
1111 respect from Debian lenny to Debian squeeze (still testing as of Oct
1113 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1115 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1117 --- 4.1.1 2010/10/05
1119 Fix yaz-config output: echo_source not set correctly by configure.
1121 --- 4.1.0 2010/10/05
1123 Solr Web Service support for yaz-client and ZOOM.
1125 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1127 --- 4.0.12 2010/08/17
1129 Z39.50 facet support. Facet specifications are passed for search in
1130 other-information with ASN.1 as defined in facet.asn and OID
1131 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1132 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1133 3 is limit (number of entries to get in response). yaz-ztest returns
1134 dummy facets if a client asks for them.
1136 --- 4.0.11 2010/07/09
1138 CCL fixes: bug 2895 and bug 3539.
1140 GR1-display: add comma in display - was removed by mistake in
1143 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1145 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1147 --- 4.0.10 2010/06/18
1149 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1150 result set from a connection. The result set will be on its own
1151 thereafter; no operations on it will perform retrievals from a target.
1152 Only cached copies are returned.
1154 ZOOM C:fix case for HTTP servers responding with Connection:close.
1155 Ensure that if there is a current task it is resumed (like fetching
1156 more records in a result set) . Bug #3484.
1158 PQF parser: use odr_atoi for Odr_int (not atoi)
1160 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1161 values that contain any non-digits are treated as string attributes
1162 (previously decoding only checked for leading character ([0-9]). PQF
1163 encoding: attribute string values are not surrounded by double-quotes.
1165 --- 4.0.9 2010/05/21
1167 New utility for managing threads - thread_create.h.
1169 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1170 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1171 but YAZ' implementation do.
1173 Fixes for yaz_cond-functions on Windows 7.
1175 DLL export more symbols.
1177 zoomsh: show record do NOT render opac.
1179 Remove *.la files from Debian and RPM packages.
1181 --- 4.0.8 2010/05/11
1183 Debian package libyaz-dev depends on libgnutls-dev again (was
1184 removed in YAZ 4.0.6, but due to Libtool it is still needed
1185 even though yaz-config do not list libgnutls libs).
1187 ZOOM: Use only one WRBUF for returning string results for
1188 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1190 ZOOM: ZOOM_connection do not use a shared pointer to
1191 ZOOM_resultset after ZOOM_resultset is destructed by
1192 user. Reverts to YAZ 4.0.4 behavior.
1194 --- 4.0.7 2010/05/04
1196 record-conv: fix problem with at least one XSL conversion -
1197 due to probably incorrect usage of XML XSL documents.
1199 --- 4.0.6 2010/04/29
1201 Fix yaz-config for static mode and the use of SSL (gnutls).
1203 --- 4.0.5 2010/04/29
1205 Forward decl timeval struct in mutex.h and gettimeofday.h.
1207 yaz-config: fix 'static' mode linking.
1209 --- 4.0.4 2010/04/28
1211 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1212 are wrappers for pthreads or Windows. For Windows these are put in
1213 a separate DLL: yaz_cond4.
1215 libyaz.la (whole source) is compiled with thread. If thread support
1216 is enabled enabled, all source of YAZ is compiled with treading support.
1217 This allows core utilities such as yaz_log to use thread facilities.
1218 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1219 thread utilities. This commit moves mutex utilities (mutex.c) from
1220 libyaz_server.la to libyaz.la.
1222 yaz-json-parse displays leading text until error.
1224 --- 4.0.3 2010/04/09
1226 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1227 patch from Giannis Kosmas.
1229 SRU: no longer URL encode SRU database. The URL for an SRU server is
1230 a URL and such is alreeady encoded - at least when given with leading
1231 http:// or https://. This reverts behavior to YAZ 3.0.50.
1233 Support for new MARC XML notation TurboMARC which like MARCXML is a
1234 complete representation of MARC/ISO2709.. This one, however, is more
1235 compact and allows for faster processing with XSLT. TurboMARC can be
1236 used in the marcdisp.h API, from the yaz-marcdump utility and from
1239 yaz-ztest can be configured - via the database - to perform certain
1240 delays when it performs operations search, present and single record
1241 fetch. This allows testers to make yaz-ztest act as a real or even slow
1242 Z39.50 server. Refer to the yaz-ztest man pages for details.
1244 --- 4.0.2 2010/03/09
1246 wrbuf_destroy allows NULL WRBUF passed to it.
1248 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1250 Add ZOOM_connection_close.
1252 No fixed size buffers for ZOOM shell - bug #3257.
1254 tstodr: make it work on s390 platform.
1256 New icu iterator-functions. The new icu_iter-functions makes it possible
1257 to use ICU chains from many threads.
1259 yaz-client: better syntax check for show command.
1261 --- 4.0.1 2010/01/26
1263 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1266 New simple local-file XML include facility which allows file glob-patterns.
1267 Refer to yaz/xml_include.h.
1269 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1272 ZOOM_record_get supports new parameter "format" which makes it format XML
1275 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1276 JSONText in ECMA-262) is JSONValue, not JSONObject.
1278 --- 4.0.0 2010/01/20
1280 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1281 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1283 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1284 POSIX/Unix builds .so with major version 4.
1286 Remove old LOG_-defines from log.h. They have been obsolete and
1287 undefined by default for the last 5 years.
1289 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1291 GFS: Remove socket (int *fd) from search_rr handler. The socket
1292 descriptor ptr is a facility that allowed a search handler to supply
1293 a socket which would serve as a callback - when search was complete.
1294 This facility has now been in use for years.
1296 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1297 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1298 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1299 returns 'const char *' rather than 'char *. The returned string is
1300 read-only and should not be modified by applications. COMSTACK cs_close is
1301 now a void function - it no longer returns int. No applications check for
1302 the value and the implementations has always returned 0.
1304 ZOOM: use size_t for scan hit counts and str size. Functions
1305 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1306 occ (hit count) and len (string length) are now of type size_t pointer
1307 rather than int pointer. This is to be able to represent large hit counts
1308 and to also just to use the proper type for string length (strlen result).
1310 New JSON parser. Refer to include/yaz/json.h .
1312 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1313 Used to be int in some cases. Many wrbuf_-functions used to return an int
1314 indicating some length.. These return values were never used. And so they
1317 ODR: odr_malloc, odr_total now takes size_t for size.
1319 clone_z_type: fix leak; occurred for encoding failures.
1321 --- 3.0.52 2009/12/03
1323 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1324 bug was introduced in 3.0.51.
1326 --- 3.0.51 2009/12/02
1328 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1330 tcpip comstack: fix leak for getaddrinfo.
1332 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1333 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1334 Decoding of SRU "path" database is performed by private function
1335 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1336 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1338 yaz-client: honor base command for SRU. Change when database setting
1339 is applied for SRU and ensure it is kept when a connection is reset.
1340 Change also the way errors are displayed or SRU (decoding of packages).
1342 --- 3.0.50 2009/11/02
1344 Add support for extra request / response data for SRU codecs and GFS.
1345 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1346 for extra data response buffer and length. For the GFS, both request
1347 and response data (XML) is carried in extra_args and extra_response_data
1348 for the search handler. Patch by Ko van der Sloot.
1350 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1351 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1352 10010). This fixes bug #2113.
1354 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1355 cmdfile included a 'quit' command that would result in a memory violation.
1357 --- 3.0.49 2009/10/01
1359 Make a number of functions defined in xmlquery.c static. These have
1360 never been declared in a public header file (yaz/xmlquery.h) and was
1361 made public by mistake.
1363 Improve speed of character conversions (iconv utilities). This makes
1364 conversions from MARC-8 faster.
1366 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1367 unless type desired is "raw". This will prevent type "xml" from
1368 returning ISO2709 .. Which obviously can not be XML parsed.
1370 Fix memory leak in ZOOM that would occur if option apdulog was used
1371 on a re-used connection.
1373 Frontend server logs HTTP requests.
1375 Frontend server now sends Z39.50 close when it times out (sesssion has
1376 been idle for too long). Versions 2.0.30 and earlier also sent close.
1377 But due to a mistake this was disabled in all versions after that, i.e.
1378 the server would just close the socket immediately.
1380 yaz-client emits a better message when receiving an unrecognised
1381 userInformationField.
1383 Skip zero-length subfields when decoding ISO2709. This rare case happens
1384 if a record has two FS characters in a sequence. Without this patch
1385 there would be a reference beyond char array in using_code_len fragments
1388 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1390 --- 3.0.48 2009/08/28
1392 The show command offered by the zoomsh command now takes a 3d optional
1393 parameter type which is what is passed to ZOOM_record. If the type
1394 argument is omitted, "render" is used.
1396 RPN to CQL conv may use USE string attributes (bug #2978).
1398 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1400 --- 3.0.47 2009/07/08
1402 Function yaz_xml2query allows a diagnostic element in the PQF XML
1403 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1404 code and additional info respectively.
1406 The BER BOOLEAN is now the integral type Odr_bool which still happens
1407 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1408 typedef'd to Odr_int. This is still an integral 'int', but it may be
1409 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1410 ASN-1 compiler as well as programs has been updated to use the new types.
1412 --- 3.0.46 2009/06/08
1414 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1415 only the bibliographic record was rendered. For type=opac, an OPAC
1416 record is only returned if it is present.
1418 iconv: small fix for encoding of advancegreek.
1420 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1422 yaz-client: option auto_reconnect=on really reconnects.
1424 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1426 server: avoid null ptr ref for for yaz_poll errors.
1428 build: fix RPM build for RHEL 5.3.
1430 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1432 --- 3.0.45 2009/03/31
1434 Fixed bug #2709: TCP connect returns Invalid argument.
1436 Fixed compilation for mingw.
1438 Honor charset for raw records (ZOOM_record_get).
1440 Fixed use of errno for threaded mode that was seen on Solaris 10.
1442 Fixed argument passing with blanks in value for Windows Service.
1444 Disable YAZ' own log rotate by default (no 1 GB limit).
1445 The variable l_max_size which specifies the log file limit is set to 0
1446 (DISABLED): This is due to the fact that YAZ is most often deployed using
1447 logrotate. Also YAZ can not perform log rotate because of unsufficient
1448 permissions (setuid).
1450 --- 3.0.44 2009/02/17
1452 List supported encodings in man page for yaz-iconv.
1454 Fixed missing SSL libs for --libs output
1456 Re-established OID record syntax application-xml. Nobody should use it
1457 but we don't want to change soname because of this symbol being absent.
1459 --- 3.0.42 2009/02/02
1461 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1463 Added member named_result_sets for init handler struct for the GFS. This
1464 allows a server to disable named result sets.
1466 Removed OID record syntax application-xml.
1468 Added support for rule-based transliterator for ICU wrapper of YAZ.
1470 Fixed bug #1902: yaz-icu XML output.
1472 Make YAZ checks Emacs friendly.
1474 BITSTRING value shows value. Bug #2346.
1476 ISO2709 decoding: skip control characters from indicator data.
1478 Omit sort key by default in yaz-icu's output.
1480 Allow combined single char options (again) for YAZ' options function.
1482 Utility yaz-marcdump got option to display YAZ version (-V).
1484 Allow YAZ to use ICU 3.4.
1486 Added new ICU test case which illustrates removal of diacritics.
1488 --- 3.0.41 2008/12/29
1490 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1492 --- 3.0.40 2008/12/29
1494 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1497 Fixed bug #2352: yaz-marcdump crashes for certain record.
1499 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1501 Added support for Danmarc2 to UTF-8 conversion.
1503 Added support for ISO5426 to UTF-8 conversion.
1505 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1506 implementation version.
1508 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1510 --- 3.0.38 2008/11/10
1512 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1513 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1515 ZOOM C now interprets databaseName option for ZOOM connection as path
1518 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1520 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1522 Dummy Libxml2 types no longer defined in headers of YAZ'.
1524 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1527 --- 3.0.36 2008/09/26
1529 Various ODR chapter fixes.
1531 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1533 Added missing source for Windows compilation, mutex.c.
1535 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1537 For SRU connections in ZOOM all records up to "count" are now fetched.
1539 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1540 in Windows due to bad error handling for Libxml2.
1542 Added facility for sending arbitrary records (ASN.1 any) using
1543 ZOOM C's Extended service update. Patch by Sam Reynolds.
1545 New options for ZOOM C's connection, logapdu which makes ZOOM log
1548 --- 3.0.34 2008/06/18
1550 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1552 --- 3.0.32 2008/06/12
1554 Fixed memory violation that could occur when decoding UTF-8. This bug
1555 was only present in 3.0.30 of YAZ.
1557 --- 3.0.30 2008/06/06
1559 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1560 GNU TLS is used by default (if found).
1562 yaz-ztest returns OPAC records if a client asks for OPAC.
1564 Improved speed of MARC-8 encoding.
1566 Added support for lossy and loss-less MARC-8 encoding.
1568 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1570 Added new Windows Service wrapper (sc).
1572 yaz-client's itemorder command may now send a file.
1574 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1576 Added new function yaz_log_xml_errors.
1578 Allow (but warn) unknown XML attributes in MARCXML parsing.
1580 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1582 The UTF-8 to MARC-8 conversion now uses a different set of characters
1583 for Greek symbols. Bug #2120.
1585 --- 3.0.26 2008/02/21
1587 Added yaz_daemon (daemon.h).
1589 Fixed bug #2068: pkg-config trouble
1591 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1593 --- 3.0.24 2008/01/28
1595 Document --with-xml2 option.
1597 Added OPAC XML XSD (etc/opacxml.xsd).
1599 Allow glob mask for name attribute in retrieval element for the
1600 generic frontend server's retrieval facility.
1602 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1603 except POLLIN/POLLOUT.
1605 Fixed error handling in cs_listen. Bug #2037.
1607 --- 3.0.22 2008/01/20
1609 Fixed version in yaz/yaz-version.h.
1611 Fixed bug #2027: Crash when closing connection.
1613 Changed configure so that ICU support is only enabled if only ICU
1614 and Libxml2 is available (because the ICU chain is XML based).
1616 --- 3.0.20 2008/01/15
1618 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1619 is built. Only this DLL depends on the ICU runtime.
1621 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1622 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1624 Changed license of CCL module to 'Revised BSD'. After consultation with
1625 remaining members of the original EUROPAGATE consortium, we are re-issuing
1626 the CCL module without a separate license. The software was developed by
1627 Index Data as part of a research project. The special license was included
1628 to help feed usage information back to the project consortium to support
1629 project evaluation. At this time, the project consortium has long-since
1630 disbanded, and the majority of the original principals have retired. At the
1631 same time, we have significantly modified the software during the following
1632 years, to the point where very practically no original code remains. To
1633 simplify re-use of the software, we have contacted those members of the
1634 consortium who could be reached, and agreed to re-issue the module as a
1635 proper part of the YAZ package.
1637 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1639 CQL closer to being version 1.2 compliant. CQL also allows free-form
1640 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1643 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1644 bug could make Extended services handling crash in the ZOOM layer. This
1645 bug was only present in YAZ 3.0.18.
1647 --- 3.0.18 2007/12/19
1649 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1652 yaz-marcdump reads and writes collection wrapped records.
1654 Handle OPAC for record conversion module.
1656 Fixes for ICU wrapper.
1658 Allow ICU libs to be controlled with --with-icu .
1660 --- 3.0.16 2007/11/12
1662 Added yaz_poll which is a wrapper for select/poll. When poll is available
1663 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1664 sockets to be in use.
1666 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1667 functionality through an XML based configuration (ICU chain). This system
1668 is useful for search facilities such as Pazpar2 and Zebra that needs to
1669 perform tokenization of indexed material. The ICU code in a separate
1670 library libyaz3_icu.a.
1672 Added HTTP tunnel facility for COMSTACK, bug #1752.
1673 This is a facility that allows a Web proxy, such as squid, to tunnel
1674 Z39.50 traffic. This facility is "transparent" to must applications
1675 using YAZ. It's enabled by using pseudo transport connect: followed by
1676 the proxy address, followed by command, then follwed by he regular
1677 "virtual" addresss. For example,
1678 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1680 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1682 --- 3.0.14 2007/09/21
1684 Fixed bad memory reference in ZOOM_record - cuased by member not being
1685 initialized. This was a problem only in YAZ 3.0.12.
1687 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1688 fields were not removed.
1690 Changed the way C code is generated from codetables.xml. Made a MARC-8
1691 conversion trie for each characterSet section rather than codeTable.
1692 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1693 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1695 --- 3.0.12 2007/09/12
1697 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1698 from ZOOM_record_error).
1700 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1702 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1704 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1706 Better SRW-to-Bib-1 diagnostic mapping.
1708 ZOOM C and yaz-client announces SRU version 1.2 by default.
1710 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1713 Fixed in yaz_sru_decode to allow other version than 1.1.
1715 --- 3.0.10 2007/08/22
1717 Added support for SRU scan for ZOOM.
1719 Added support for the use of the older versions or Extended Service
1720 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1721 set to the version , 1=first, 2=second, 3=third. The third version is
1722 what ZOOM C has used so far. And that, obviously, is the default.
1724 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1725 therefore in Zebra and in SimpleServer-based applications). The new
1726 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1727 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1728 which is passed into the back-end search callback function.
1730 Added support for HTTP Basic authentication in clients: the SRU/W
1731 codec encodes the username/password elements of the PDU structure
1732 appropriately, and these may be set using the "user" and "password"
1733 options in ZOOM-C applications (the same options that are used for
1734 Z39.50 authentication).
1736 --- 3.0.8 2007/06/25
1738 Fixed bug #1208: SSL appears to be broken in ZOOM.
1740 Fixed bug #1206: Libxml2 include path weirdness.
1742 Added oid_name_to_dotstring.
1744 Allow elementSetName to be specified for ZOOM C record update.
1746 Allow waitAction to be specified for ZOOM C based for Extended Services.
1748 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1749 syntax OID. Bug introduced in YAZ 3 series.
1751 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1753 --- 3.0.6 2007/06/06
1755 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1756 directory. yaz-client now reads commands from file given by option -f
1757 if specified; then tries to read .yazclientrc in current directory.
1758 Failing that, it reads .yazclientrc from user's home directory.
1760 Added support for correlationInfo Note and ID for Record Update via
1763 Added yaz-client command querycharset which specifies character set for
1764 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1765 (termListAndStartPoint).
1767 Charset ISO5428:1984 is an alias for ISO5428-1984.
1769 Implemented a way to perform scan in a result set using Z39.50. This
1770 is achieved by attaching the result set name in the characterInfo
1771 (type InternationalString) of OtherInformation in the Scan Request PDU.
1772 The result set is identified in the otherinformation by the new OID:
1773 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1774 This allows for scan in result set and faceted search . Zebra did some
1775 of this in the APT term using attribute type 8 and value being result
1776 set. Using the OtherInformation approach for this is cleaner and easier
1777 to work with in proxies and the like. This facility can be used in
1778 yaz-client using new command setscan which takes a result set as first
1779 argument, start position (APT) as second.
1781 Changed decoding of SRU XML packed records to deal with servers that
1782 have recordData with XML data with multiple root nodes. Also make
1783 comparison for recordPacking case insensitive. Again, one server
1784 returns "XML" where others return "xml".
1786 For SRU responses allow Content-Type application/xml as well as text/xml.
1788 --- 3.0.4 2007/05/21
1790 Fixed bug in character set conversion of BER strings. Bug introduced
1793 --- 3.0.2 2007/05/08
1795 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1797 For OID class, use oid_class consistently.
1799 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1802 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1803 character set for bibliographic information interchange". By Giannis Kosmas.
1805 Added documentation on new OID API.
1807 --- 3.0.0 2007/05/02
1809 Changes to generic frontend server interface: added new member
1810 'query_charset' for bend_initrequest structure. A backend init handler
1811 should set this member to its native character set for query terms.
1812 When defined, the frontend server logic will announce this character set
1813 to a client if the negotiationModel bit is set by the client. All server
1814 implementors are encouraged to specify this. If a backend server does not
1815 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1817 Added CCL utility to remove terms (stop words) from resulting RPN
1818 tree. This is handled by functions with prefix ccl_stop_words_ .
1820 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1821 terms in RPN queries.
1823 Clean-up the CCL API. Moved some internal structures from ccl.h to
1824 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1825 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1826 This is replaced by ccl_parser_find_str which takes a string instead.
1828 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1829 libyaz.la is the core of YAZ except the generic frontend server and
1830 does not depend on POSIX threads anymore. libyaz_server.la is the
1831 generic frontend server facilities and uses POSIX thread functionality
1832 if available. The libyaz.la no longer depends on POSIX threads because
1833 the number of global structures is limited. NMEM no longer re-uses blocks
1834 between threads ; it simply free's memory immediately but allocates in
1835 "large" chunks as usual. We don't expect any performance penalties
1836 because of this. The yaz_log system is still using a global log_level so
1837 caution must be taken when modifying it with yaz_log_init_.. +
1838 yaz_log_mask_str. This, however, should not cause any trouble because
1839 these functions are called during initialization of application code
1840 anyway. `yaz-config --libs server` returns libs for server applications;
1841 `yaz-config --libs` returns libs for non-server applications.
1843 New OID database - with public definitions in oid_db.h. Removed old OID
1844 database including the head oid.h and definitions such as enum oid_value
1845 and struct oident. The new OID database uses the same string names as
1846 before but the 'protocol' is gone. There are now only two representations
1847 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1848 converts from string to OID; functions with prefix yaz_oid_to_string
1849 converts the other way.
1851 Change to emit_term() in CQL-to-PQF query translation: when a term has
1852 the /regexp relation modifier, do not process it for leading and
1853 trailing "^" and "*", which have quite different meanings in regular
1856 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1857 write handlers no longer carries a 'last' parameter. This will make
1858 yaz_iconv flush "less" characters. A flush is performed by call to
1859 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1861 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1862 removed, because function yaz_query_to_wrbuf does the same.
1864 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1865 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1867 Deprecated MARC utility functions removed.
1869 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1872 Branch split: YAZ_2_1_55_branch
1874 --- 2.1.54 2007/03/16
1876 Fix to ZOOM-C so that transparent reconnection is properly handled on
1877 connections that are in asynchronous mode.
1879 Fixed compilation on OpenBSD 4.0.
1881 Large strings in GRS-1 records are now properly displayed in yaz-client.
1883 Added character conversion support for "advancegreek"; based on patch from
1886 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1887 sequence is met. Before the error was not set so it would be unknown.
1889 Adjust yaz-marcdump MARC reader so that it skips until record separator
1892 --- 2.1.52 2007/03/07
1894 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1895 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1896 fd_set structure used as a bitmask for the FDs to be selected on.
1898 Using ACX_PTHREAD macro to check for POSIX threads.
1900 Fixed have-vsnprintf check.
1902 --- 2.1.50 2007/02/23
1904 Fixes for configure on BSD. Bug #900.
1906 Added snprintf/vsnprintf wrappers for systems that don't have
1907 limits (heavens forbid).
1909 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1910 created before all previous tasks were completed and removed from the
1911 task queue, the new task could be removed by a mistake.
1913 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1915 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1917 Fixed bug #832: Problem with MARC/charset in yaz-client.
1919 Fixed bug #668: save command line history for yaz-client.
1921 Fixed bug #830: pkg-config support.
1923 --- 2.1.48 2007/01/23
1925 Extended ZOOM result set options with two options that may be read by
1926 a client: resultSetStatus and presentStatus with values as specified for
1928 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1930 Fixed bug #827: Using SSL fails on Debian etch.
1932 Fixed bug #826: Weird looking chars for set of MARC records.
1934 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1935 that is treated as an ItemOrder with itemRequest being an XML document
1936 external. The value of "doc" is the content.
1938 Extended the GFS search facility. New member of bend_search_rr
1939 'estimated_hit_count' signals that hits is known to be an estmate
1940 (higher or lower than real hit count). New member 'partial_resultset'
1941 signals that the search was partial (hit count is lower or equal than
1942 real hit count). For Z39.50, the information is stored in resultSetStatus
1943 member of SearchResponse APDU. For SRU, the information is signalled
1944 via SRU diagnostic 59: "Result set created with valid partial results
1947 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1949 --- 2.1.46 2007/01/13
1951 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1953 Added ZOOM_connection_peek_event.
1955 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1956 the following new functions:
1957 ZOOM_event_nonblock, ZOOM_connection_process,
1958 ZOOM_connection_get_{socket,mask,timeout},
1959 ZOOM_connection_fire_event_{timeout,socket}.
1960 The existing blocking event handler, ZOOM_event, is a wrapper for the
1961 + blocking ZOOM_event_sys_{poll,select}.
1963 Implemented function ccl_xml_config which parses XML version of CCL
1964 configuration (bug #798).
1966 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1968 Added timings utility (yaz/timing.h)
1970 --- 2.1.44 2007/01/03
1972 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1975 Fixed bug #779: Rotation of apdu.log fails.
1977 Fixed for character set conversions:
1978 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1979 Honor G1 set in MARC-8 decoding.
1981 --- 2.1.42 2006/12/17
1983 Fixed bug #775: char conversion does not handle Alternative UTF-8
1986 Implemented function yaz_marc_read_line which parses MARC line format
1987 records. There is a wealth of formats out there. So far, this function
1988 reads line records produced by yaz_marc_write_line.
1990 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1991 more generic and easier to remember(!) options: -i format and -o format
1992 which specifies input format and output format respectively - where
1993 format is one of "marc", "marcxml", "line", "marcxchange".
1995 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1996 does not print anything except warnings for records.
1998 For yaz-marcdump, added support for MARC split into files (-s) with a given
2001 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2002 spec, at http://www.loc.gov/standards/sru/record-update/
2003 This has changed the binary layout of the following structs:
2004 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2005 bend_update_rr . Patch by Ko van der Sloot.
2007 Added GFS utility function bend_assoc_is_alive which returns 1 if
2008 association is still alive (client is connected); 0 otherwise (client
2009 closed connection). This allows busy servers to stop working for
2012 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2013 been a separate piece of software. This version of ziffy has been modified
2014 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2016 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2018 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2019 Client code may now interrogate options such as "init_opt_sort" to
2020 find out whether the server claims to support various options.
2022 --- 2.1.40 2006/11/27
2024 Added utilities yaz_{set,get}_esn to set/get element set name from
2027 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2028 of YAZ and has been so since YAZ 2.1.10.
2030 Implemented ZOOM_record_error which returns error information for
2031 record (surrogate diagnostic).
2033 --- 2.1.38 2006/10/31
2035 Updates for SRU Update by Ko van der Sloot:
2036 1. Changed name from "operation" to "action"
2037 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2038 versions in the code, marked as 'backward compatible'.
2039 3. Added diagnostics for SRU Update.
2041 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2043 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2045 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2047 For GFS, fixed problem with SRU diagnostic 'First record position out of
2048 range' being issued for 0 hits.
2050 zoomtst10 part of Windows Build.
2052 --- 2.1.36 2006/10/13
2054 Implemented yaz_filepath_comp which splits a path into file path
2055 components (required by Zebra 2.0.3+).
2057 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2058 BSD inspired license until now so this should not have any real impact on
2059 anybody. See http://www.opensource.org/licenses/bsd-license.php
2061 Fixed bug #687: Missing log lines.
2063 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2066 Fixed bug #689: SRU diagnostics to be added.
2068 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2069 whether a connection is idle (no more work do do).
2071 --- 2.1.34 2006/10/04
2073 Change type of optval from long to int for invocation of setsockopt with
2074 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2076 Added support for specifying the max log file size for the Generic
2077 Frontend Server. The size is given with option -r.
2079 --- 2.1.32 2006/09/21
2081 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2083 --- 2.1.30 2006/09/17
2085 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2088 Fixed bug in Generic Frontend Server that could cause a server to stop
2089 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2091 For the generic frontend server, the maximum record size is used as maximum
2092 size of incoming packages (SRU + Z39.50). The value until was previously
2093 only used in Z39.50 Init negotiation and, later, in a session controlled
2094 sizes of records returned. This is controlled using -k option. It can be
2095 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2097 --- 2.1.28 2006/09/04
2099 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2102 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2104 New option for yaz-marcdump -lpos=value which allows setting a portion
2105 of MARC header to a certain value.
2107 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2109 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2110 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2112 --- 2.1.26 2006/08/15
2114 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2117 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2119 --- 2.1.24 2006/08/08
2121 Fixed MARC ISO2709 encoding routines to deal with character set
2124 Minor changes to GFS logging. Database included in search request log
2127 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2128 cached/multiple records.
2130 Shared libraries are built by default on Unix+configure.
2132 Changed cql2pqf transformation to use a different evaluation order. The
2133 new order is: always, relation, structure, position, truncation, index
2134 and relationModifier. Old order was: always, relation, relationModifier,
2135 structure, index, position, truncation. Note that the the latter ones
2136 override former ones for identical attributes.. The new scheme means that
2137 it is possible to override any existing attribute with a relationModifier.
2138 And also that it is possible to override everything for the index rule
2139 (except the ones listed in relationModifier). No order is perfect but this
2140 one, we believe, covers more real cases.. The "always" should have been
2141 called "default", since the attributes there can be overridden with all
2144 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2145 compilation phase, but also for yaz-config --cflags output. This allows
2146 us to have public headers with Libxml2 stuff in them . It should also,
2147 eventually, make Libxml2 checks redundant in packages using YAZ, such
2150 --- 2.1.22 2006/06/15
2152 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2153 stored in uri, message and details.. Previously diagnostics were stored
2154 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2155 compatibility.. but he's probably the only one affected, so.
2157 Added support for CCL, compiled on the client side, in ZOOM-C. This
2158 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2159 input; the resulting query objects can be used for for searching with
2160 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2162 YAZ' configure searches for OpenSSL by default.
2164 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2165 SL_CTX_use_certificate_file. See
2166 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2167 for more info. Thanks to Ko van der Sloot.
2169 --- 2.1.20 2006/06/02
2171 Bug #600: SRU GET, POST support for yaz-client. Introduced
2172 command 'sru' which selects method SOAP/GET/POST.
2174 Allow missingValueAction to be specified for the sortspec string -
2175 function yaz_sort_spec. By default, the missing value action is null.
2176 Use ! to specify "abort". Use = followed by stringvalue to specify default
2179 Ensured that Present-handler (if defined) is called in GFS before any call to
2180 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2181 searchRetrieve requests.
2183 Documentation for YAZ is now based on the Docbook XML/XSLT using
2184 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2185 is no longer depending on jade/openjade or docbook-to-man scripts.
2186 PDF is no longer part of the distribution - but can optionally be
2187 made using DSSSL/jadetex or FOP.
2189 Added retrieval handling support in Generic Frontend Server to support
2190 conversion between MARC/XML as well as XSLTtransforms. See
2191 etc/yazgfs.xml for an example.
2193 Added Authentication support to Generic Frontend Server in SRU
2194 mode. Authentication using HTTP Basic is supported, as is the use
2195 of 'x-username' and 'x-password' parameters in the request itself.
2197 Added support for a new character set MARC8s identical to MARC8 except
2198 that it converts combined characters to single Unicode characters in the
2199 Latin-1 range (when possible).
2201 --- 2.1.18 2006/04/24
2203 ASN.1 compiler 0.4: generates brief Doxygen file header for
2204 generated .h/.c files.
2206 Utility yaz_iconv now supports conversion to MARC-8.
2208 New facilities for the MARC module. The reading - and writing of
2209 content are separate methods for the yaz_marc_t handle. The following
2210 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2211 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2212 format). Write functions have prefix yaz_marc_write_.. The existing
2213 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2214 available. Removed support for OAI-MARC and simplexml (not the
2215 simplexml from PHP5).
2217 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2218 to be returned for this connection.
2220 --- 2.1.16 2006/03/31
2222 Allow multiple languages and charsets to be specified with
2223 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2224 negcharset iso-8859-1,utf-8
2226 Translation of proximity nodes from CQL into PQF now works.
2228 Moved to automake 1.8, 1.9.
2230 Added function yaz_log_set_handler which allows a log handler to be
2231 installed. This handler will be called for all log messages. Output
2232 to file is also produced; but that can be disabled by passing NULL
2233 fname to yaz_log_init_file.
2235 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2237 For SRW (including GFS), accept application/soap+xml as content-type
2240 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2241 produces NO stylesheet reference even if a default stylesheet is specified
2244 --- 2.1.14 2006/03/14
2246 Updated Windows package to include yazd.dll + yazd.lib for the
2247 Development component.
2249 If the environment variable YAZ_LOG is set, then it is used as a
2250 string indicating the default level of logging to use if not
2251 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2252 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2253 used as before. So, for example, to omit warnings from YAZ logging,
2254 export YAZ_LOG=-warn
2256 cql_transform() now map structure and other attributes before indexes,
2257 so that index-specific structures and other attributes can override
2258 defaults. So now a combination of mapping specifications such as:
2260 index.dc.date = 1=date-modified 4=5
2261 does the right thing.
2263 cql_transform() now also respects the "always" mapping specification,
2264 which establishes an initial set of attributes to be used for all
2265 terms except where overridden by more specific attributes associated
2266 with the index, relation or modifier.
2268 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2269 which mode to use; one of "post", "get" or "soap" (SRW, default).
2271 Fixes for yaz_iconv routines: changed trie-based character set conversions
2272 to use only non-negative values for bit fields due to Sun's C compiler not
2273 supporting negative values.
2275 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2276 sequences where not read correctly. Fix by Rustam Usmanov.
2278 Updated win/makefile to use options, settings which makes things
2279 compile with VS C 2005.
2281 --- 2.1.12 2006/02/01
2283 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2285 In ZOOM socket code, use select instead of poll on MacOSX.
2287 ZOOM-C now support client-side compilation of CQL into RPN that is
2288 sent to the server, enabling CQL to be used against all Z39.50
2289 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2290 ZOOM_query object, and submit it using ZOOM_connection_search().
2291 The CQL-to-RPN translation uses a configuration file, the name of
2292 which must be specified in the Connection's "cqlfile" option.
2294 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2295 function, which takes as its start-term parameter a ZOOM_query object
2296 (which may have had either CQL or RPN set into it).
2299 --- 2.1.10 2005/11/29
2301 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2302 GFS to support this as well. Backend handler, bend_srw_update, does the
2303 update work. Code contributed by Ko van der Sloot.
2305 Allow retrieval of Search Result-1 information in ZOOM by the use of
2306 options that are attached to a result set. ZOOM documentation updated
2309 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2310 UTF-8 conversion. Patch by Raj Patel.
2312 Added option -m to GFS to control formatting of timestamps in log file.
2314 Added 'exit' as synonym for 'quit' in yaz-client
2316 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2317 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2318 for the new members. Patch by Ko van der Sloot.
2320 Added support for SRU POST. It is supported for content-type
2321 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2323 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2324 Instead make the library libyaz.la multi-threaded. Threading as a whole
2325 can still be disabled by configure option --disable-threads. Previosly,
2326 with older GLIBCs there were problems with MT libs under Apache. This
2327 has now been fixed a long time ago.
2329 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2332 CQL module modified to be case insensitive for relations/indexes/operations.
2334 Fixed bug in CQL transform code: incorrect value relationModifieder
2337 Added 'show all' command for yaz-client which retrieves all results
2340 Added new yaz-client, xmles, which takes a (private) OID and
2341 a document to be sent as an extended service request.
2343 Describe new yaz-client commands wait_response and set_auto_wait.
2345 Increase TCP/IP listener backlog from 3 (which I am guessing was
2346 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2347 that the socket will queue as many incoming connections as it's able
2348 to handle ongoing connections. In other words, it will never now
2349 refuse a connection that it would be able to handle merely because
2350 it's not got around to accepting() enough of the pending connections
2351 yet. This is the behaviour anyway under Linux, where the listen()
2352 argument is ignored; but not under BSD and on systems such as
2353 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2354 YAZ-based servers should now be uniform across operating systems in
2357 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2358 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2359 This allows yaz-marcdump to read large MARC batches (>2 GB).
2361 Modified all YAZ source files - except the source which is auto-generated
2362 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2365 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2366 corresponding to the existing *_setl() function. These allow option
2367 values containing arbitrary valuues.
2369 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2370 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2371 except that it returns an indicator of whether or not the sort
2372 criterion was accepted (0 for OK, -1 for invalid).
2374 --- 2.1.8 2005/06/07
2376 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2377 MARC output rather than returning "new" buffer.
2379 yaz-client warns about unknown init options.
2381 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2383 --- 2.1.6 2005/05/24
2385 Added support for SRW sort in Generic Frontend Server. Patch
2386 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2387 sortKeys - or NULL if none is provided.
2389 Fixed bug #307: It was impossible to specify indefinite/no timeout
2390 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2393 Added support for multiple languages and charsets to be specified in
2394 ZOOM. Each charset/language is separated by a blank. If negotiation is
2395 in effect in init-response, Option
2396 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2397 Code based on patch by Vasiliy Osadchuk.
2399 Fixed bug #306: infinite recursion that occurred when calling
2400 yaz_log_level_init as the first call (before other log level or
2403 Fixed bug in scan handling in front end server: if preferred-Position-In-
2404 Response was non-present, a NULL pointer referece was performed.
2406 --- 2.1.4 2005/04/26
2408 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2409 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2410 now defined for all those error codes. So instead of putting 109 in
2411 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2412 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2414 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2417 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2419 Program yaz-client now exits and produces an error message if multiple
2420 Z39.50 servers are specified on the command line (none or one allowed
2423 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2426 --- 2.1.2 2005/03/16
2428 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2430 Fixed bug #272: Preserve spacing for CCL terms.
2432 --- 2.1.0 2005/03/14
2434 Added support for virtual hosts and multiple backend servers for
2435 the YAZ frontend server. The configution is XML based and
2436 support specificition of CQL to RPN mappings and explain information.
2437 See section "Virtual Hosts" in the YAZ manual.
2439 Extended OPAC display utility. OPAC display utility renders
2440 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2441 to supplement yaz_marc_decode_wrbuf.
2443 Fixed a bug in MARC decoder that could caused it to crash for some
2444 invalid MARC records. More diagnostics and warnings where added in
2445 XML output (warnings, etc are stored in comments).
2447 --- 2.0.34 2005/02/08
2449 Fixes for UNIX domain sockets. Bug #261.
2451 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2453 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2454 Added yaz_marc_subfield_str which defines subfield lead string which is
2455 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2456 yaz_marc_endline_str which defines end of fields string used in
2457 YAZ_MARC_LINE format. Default string is newline.
2459 Experimental support for MarcXChange. This format can be produced
2460 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2461 http://www.bs.dk/standards/MarcXchange.xsd
2463 Added yaz-client commands scansize that sets maximum number of
2464 entries to be returned by scan.
2466 --- 2.0.32 2005/01/11
2468 Added support for SRW scan in yaz-client and Generic Frontend Server.
2470 * Added whereInList member to SRW Scan Term.
2472 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2474 Fixed NMEM system to return aligned blocks on the smallest boundaries
2475 that are suitably aligned for all possible types on the particular
2476 architecture YAZ is being built for.
2478 --- 2.0.30 2005/01/04
2480 Fixed numerious warnings that was issued with newer versions of GCC.
2482 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2483 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2486 Make YAZ Generic Frontend Server slightly faster.
2488 Enhance (and reduce) logging for Generic Frontend Server.
2490 Revert YAZ log system so that it flushes every write operation
2491 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2493 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2494 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2495 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2496 will effectively disable old definitions.
2498 --- 2.0.28 2004/11/09
2500 Added yaz_log_time_format which specifies log format using
2503 Added yaz_log_module_level which returns mask for a module. Value
2504 is non-zero mask a if module is enabled; zero if disabled.
2506 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2507 in include/yaz/cql.h.
2509 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2511 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2513 Fixed bug #172: RPM builds does not enable SSL.
2515 Doxyfile.in part of dist. Doxyfile generated by configure.
2517 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2518 are given and the corresponding component does not exist.
2520 Extend CCL documentation in YAZ reference. Describe r=r.
2522 --- 2.0.26 2004/10/01
2524 Fixed MARC->MARCXML conversion to properly deal with
2525 fields, subfields, indicators having non-ASCII characters.
2527 Fixed MARC->MARCXML conversion so that ASCII control characters
2528 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2531 Added YAZ GFS support for conversion from Z39.50 surrogate
2532 diagnostics to SRW surrogate diagnostics.
2534 Bug fix: YAZ GFS did not return schema in explainResponse.
2536 --- 2.0.25 2004/09/30
2538 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2539 now converts recordSchema to elementSetName as well as schema URI.
2541 Fixed bug in COMSTACK that prevented HTTP request packages from being
2544 --- 2.0.24 2004/09/29
2546 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2547 does not require white-space before and after the dash in a range, e.g.
2548 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2551 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2552 due to new GCC removing "redundant" code.
2554 Added yaz-client commands scanpos and scanstep that sets preferred
2555 position and step-size for scan.
2557 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2559 Added CCL utility ccl_qual_buf which parses one or more CCL
2560 spec lines in a buffer.
2562 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2563 of name and value - ignoring empty lines and comments.
2565 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2567 Added odr_get_element_path which returns current element path for an
2568 ODR handle. This utility is useful in error handling or user-defined
2571 Added ODR_PRINT utility odr_set_stream which is is a more generic
2572 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2573 to a write function and pointer to close function. The close function - if
2574 non-NULL - will be called during odr_destroy.
2576 Fixed bug in CCL parser where truncation char was not removed from
2577 right side when truncation=both was in effect.
2579 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2582 --- 2.0.23 2004/08/11
2584 Fix buffer overrun in CQL parser when dealing with proximity (%).
2586 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2587 to UTF-8/UCS conversion is now only based on codetables.xml.
2589 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2591 --- 2.0.22 2004/08/06
2593 Add support for more "commit changes" in ZOOM (uses Extended Services).
2595 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2598 Yet another small fix for configure of SSL.
2600 --- 2.0.21 2004/05/14
2602 Fix SSL libs for configure when --with-openssl=DIR is given.
2604 --- 2.0.20 2004/05/10
2606 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2608 SSL comstack now uses yaz.pem certificate file on server side
2609 by default. Certificate filename can be configured by calling
2610 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2612 Fix bug regarding multiple calls to ZOOM_connection_connect.
2614 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2616 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2617 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2619 ZOOM now allows inspection of X509 peer certificate for verification.
2620 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2622 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2623 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2624 as "modular" but it simplifies things.
2626 Added cs_get_peer_certificate to that returns peer X509 PEM.
2628 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2629 NULL if SSL is unavailable.
2631 Documentation about MARC decoding tools.
2633 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2635 --- 2.0.19 2004/03/30
2637 Rename CHANGELOG to NEWS to follow GNU style packing.
2639 Fix bug with missing initialization of member in init_diagnostics.
2640 This bug affects threaded version of GFS server.
2642 --- 2.0.18 2004/03/20
2644 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2647 Ensure zlib.dll is packed with Windows install.
2649 --- 2.0.17 2004/03/17
2651 Fix encoding of xsd:string to use text instead of CDATA.
2653 Fix endless loop in CQL parser with unbalanced ".
2655 Use a more compact way to store MARC-8 conversion tables.
2657 --- 2.0.16 2004/03/16 Debian only
2659 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2662 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2667 --- 2.0.15 2004/03/01
2669 Another fix for decoding of XML packed records.
2671 --- 2.0.14 2004/02/25
2673 Fixes for Chunked encoding. White space not ignored after length spec.
2675 Update NS and use default NS for SRW diagnostic elements.
2677 --- 2.0.13 2004/02/23
2679 Implement ZOOM_resultset_cache_reset which resets record cache.
2681 Implement ZOOM_resultset_sort which sorts a result set.
2683 Implement chunked HTTP transfer.
2685 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2687 --- 2.0.12 2004/02/16
2689 Added member 'schema' to bend_explain_rr structure so that backend
2690 can specify explain record identifier. Defaults to Zeerex 2.0.
2692 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2694 --- 2.0.11 2004/02/16
2696 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2699 Added init command for yaz-client which sends "extra" init request.
2701 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2702 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2704 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2706 Make ZOOM error code for "invalid query".
2708 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2710 --- 2.0.10 2004/02/05
2712 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2715 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2717 Added option -p <file> to make Generic Frontend Server to write PID file.
2719 Added option -D to put Generic Frontend Server in background on its own.
2721 Make ZOOM C recognize option "password". If unset, "pass" is used
2722 (for backwards compatibility).
2724 Fixed a bug in Generic Frontend Server that could make it crash if a
2725 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2728 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2729 Must be issued before open, in order to be in effect.
2731 --- 2.0.9-6 2004/01/12 Debian/Windows
2733 Make the SRU server more picky WRT unknown params, etc.
2735 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2737 New YAZ client command, options, that sets Z39.50 options.
2739 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2740 options from a string of tokens (one token for each option bit).
2742 Update SRW diagnostic code messages.
2744 --- 2.0.9-5 2004/01/07 Debian/Windows
2746 Handle user defined stylesheet for SRW/SRU.
2748 --- 2.0.9-4 2004/01/06 Debian/Windows
2750 Fix bug in decoding of Content-Length.
2752 --- 2.0.9-3 2004/01/06 Debian/Windows
2754 Fix a bug with decoding of XML packed records.
2756 --- 2.0.9-2 2004/01/05 Debian only
2758 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2760 Fix bug in SRW/SRU diagnostics decoding.
2762 --- 2.0.9 2004/01/05
2764 Fixed bug in Generic Frontend Server which could drop records exceeding
2765 preferred message size. Reported and fixed by Irina Dijour.
2767 Fixed calculation of package size for structured records in Generic
2768 Frontend Server. Reported and fixed by Irina Dijour.
2770 Fixed namespace for SRW/SRU diagnostics.
2772 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2774 --- 2.0.8 2003/12/22
2776 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2777 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2780 CQL changes to reflect recent changes to the specification:
2781 * Documentation talks about context sets instead of index sets.
2782 * Documentation talks about indexes instead of qualifiers.
2783 * The CQL-to-PQF transformer's configuration file now uses
2784 "index.set.name = <attributes>" instead of the old form
2785 "qualifier.set.name = <attributes>". (Both forms are still
2786 understood but the latter is deprecated.)
2787 * CQL terms with no explicit index specified are now interpreted as
2788 cql.serverChoice instead of srw.serverChoice (which of course
2789 behaves exactly the same.)
2791 --- 2.0.7 2003/12/16
2793 MARC conversion can now generate ISO2709 output in another
2794 character set. yaz-marcdump uses this facility if you invoke it
2797 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2798 functions from there can be used from C++.
2800 --- 2.0.6 2003/12/04
2802 Frontend server now transfers memory from decoded packages to stream
2805 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2806 references to show up.
2808 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2809 the ZOOM Abstract API. The older names for the same options are still
2810 also supported for the benefit of old applications.
2812 ZOOM-C supports "implementationId" and "implementationVersion" options
2813 to go along with "implementationName". These allow the user code to
2814 specify identification strings to be sent to servers.
2815 Add OID for the new ExtLite attribute set.
2817 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2818 as requested/supplid by Ere Maijala <ere@atp.fi>
2820 For generic frontend server, reverse the order of
2821 "toolkit-supplied / application-supplied" strings sent as implementationId,
2822 Name and Version. Also, remove the spaces around the slash. This brings
2823 the GFS in line with the behaviour of ZOOM-C on the client side.
2825 Add function ZOOM_scanset_display_term.
2827 yaz-client shows scan displayTerm if present.
2829 Utility yaz-iconv is now installed by default along with the man page
2832 Extend configure check for OpenSSL to use pkg-config where available (such
2835 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2836 server to specify uid/gid/mask for socket using the format
2837 unix:[user=uid,][group=gid,][umask=mask,]file=path
2838 If file= is omitted the existing format is assumed, e.g.
2840 in which case the mask is 0666 (rw for everybody).
2842 Major restructure of YAZ source. All source in libyaz is in src directory.
2843 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2844 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2846 Added man page for utility yaz-marcdump (used to be called marcdump).
2847 yaz-marcdump is installed by 'make install'.
2849 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2850 of incoming package failed.
2852 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2854 Change prototype of odr_perror: add const to message string.
2856 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2858 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2859 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2860 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2861 DNS lookup. There should not be any compatibility problems with this
2862 assuming that blocking=1 or 0 is used.
2864 Fix bad reference in UNIX comstack in function cs_addrstr.
2866 Fix for compilation on AIX.
2868 The generic front-end server (server/seshigh.c) now supports returning
2869 Init diagnostics to the client in User-information-field, in
2870 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2873 --- 2.0.4 2003/09/04
2875 Allow any CQL relation (not just all,any,exact,scr).
2877 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2878 that features the same UI.
2880 Implemented command update0 in YAZ client which is equivalent to
2881 update but uses old of Ext Update ASN.1.
2883 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2884 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2885 Previously no OID was used for this info.
2887 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2888 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2889 returns 'malformed search term' otherwise.
2891 SortResponse member resultCount now set to NULL in sort handler of
2894 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2897 Add three new utility functions for translating OIDs between various
2898 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2899 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2900 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2901 char *oid_to_dotstring(const int *oid, char *oidbuf);
2902 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2904 Reverted modifications for ES Update definition for z_IU0Update
2905 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2906 is back to YAZ 2.0.2.
2908 String value attributes for CCL parser.
2910 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2911 which their FirstSearch server returns in Init responses, sometimes
2912 carrying useful diagnostic information when Init fails. This has the
2913 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2914 "z39.50/oclcui.asn", where its definition is somewhat different from
2915 what OCLC document on their web-site, as required to interoperate with
2918 Support for anonymous authentication in yaz-client. Use the command
2921 * Fix the OID of the Index Data-local "admin" Extended Service from
2922 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2923 the 1000, which indicates a locally-defined OID, was a mistake.
2925 --- 2.0.3 2003/06/20
2927 Fix CCL directive @case handling so that it affects string match for
2928 both CCL keywords and qualifiers.
2930 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2931 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2932 Decoder has been updated with ASN.1 changes as listed in
2933 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2934 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2935 z_IUUpdate, remains unchanged.
2937 ZOOM_record_get may now return a record in a specific character set.
2938 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2939 "from" is the character set of record as returned by target. "to" is
2940 the character set to be returned. If omitted, "to" is UTF-8.
2942 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2944 New ODR utility, odr_getelement, which returns name of element for
2945 which encoding/decoding failed.
2947 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2948 in cases where a required element was omitted.
2950 Bug fix: some MARC8 sequences were not converted.
2952 New ZOOM option "step" which specifies number of records to be
2953 retrieved in one chunk. Used in conjunction with "start" and "count".
2955 SRW support for yaz-client. Use scheme http: to use it, e.g.
2958 yaz-client no longer does (un)intelligent character set conversions
2959 by default. Can be enabled with charset and marc_charset commands.
2961 xmalloc trace fix for 64-bit systems such as DEC alpha.
2963 Solaris 2.6 compile fix.
2965 New function, cql_strerror() translates SRW error codes, as returned
2966 by cql_transform_error(), into human-readable English strings. Used
2967 in yaz-client diagnostics when appropriate.
2969 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2970 converts it into a type-1 query which is sent to the server. This
2971 makes CQL available for use with all Z-servers, as opposed to the tiny
2972 minority that can handle CQL queries themselves.
2974 --- 2.0.2 2003/04/28
2976 New Debian package layout similar to the Redhat Package layout.
2978 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2979 and search result respectively.
2981 --- 2.0.1 2003/04/25
2983 Redhat package is now several packages: libyaz (runtime libraries),
2984 libyaz-devel (development and documentation, and yaz (utility programs).
2985 Package spec file by Morten Bogeskov.
2987 New member 'schema' in struct bend_fetch_rr which the name of requested
2988 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2989 handler MAY set this to reflect the schema of the returned record.
2991 New member 'display_term' in struct scan_entry. GFS now sets member entries
2992 and allocates scan entries to be filled by user scan handler. In previous
2993 version, entries member was allocated by the scan handler. That still works,
2994 but the GFS will ignore member display_term - assuming it was NOT set by
2995 the handler. The fact that the GFS now allocates the entries both allows
2996 for new members and makes a scan handler easier to write.
2998 Fix CQL lex buffer overflow.
3000 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3001 SRU default recordPacking is string.
3003 SRU protocol support for frontend server.
3005 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3007 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3009 Added scan for the ZOOM shell (zoomsh).
3013 * String Identifers for Schemas (Amendment 5).
3014 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3015 Old definition for schema
3016 Odr_oid *schema; /* OPT */
3021 Z_InternationalString *uri;
3022 #define Z_Schema_oid 1
3023 #define Z_Schema_uri 2
3026 * resultCount parameter to Sort Response (Amendment 1).
3027 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3029 Support for SRW 1.0 over HTTP. This is an optional feature and
3030 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3033 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3034 on the same port. SRW SearchRetrieveRequests are mapped
3035 to bend_init,bend_search,bend_fetch,bend_close.
3037 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3039 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3040 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3042 ZOOM connections are SRW based if schem http is used for hostname
3043 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3044 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3046 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3047 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3048 distance=n, order=true/false, relation=le, prox unit=word. If
3049 n is omitted, distance 1 is used.
3051 Fixed problem with C compiler include path in wrong order.
3053 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3054 on Solaris. Patch from Ko van der Sloot.
3056 New MARC decode API. All new functions operate on a yaz_marc_t
3057 handle. The most important new functions are: yaz_marc_create,
3058 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3059 decode and destroy respectively. Decoder can produce formats
3060 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3061 include/yaz/marcdisp.h.
3063 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3064 to UTF-8, UCS-32, wchar_t or Latin-1.
3066 * Prototypes for yaz_iconv_-functions moved to separate header
3067 include/yaz/yaz-iconv.h.
3069 Make a few private functions 'static' in unix.c. This prevents
3070 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3072 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3073 are set when Init Response is received.
3075 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3076 but returns diagnostic set as well.
3078 New function yaz_strerror which is a portable wrapper for
3079 strerror/strerror_r/GetLastMessage.
3081 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3082 is returned for MARC. If type is "oai", then OAI MARC is returned.
3084 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3087 --- 1.9.2 2002/11/26
3089 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3091 Fix bad race conditions on SIGTERM and terminate gracefully in
3094 Move retrieval (data1) module to Zebra since nobody seems to be
3097 Add GRS-1 render for ZOOM using same format as yaz-client.
3099 --- 1.9.1 2002/10/05
3101 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3103 Fix broken ESpec handling in data1 module.
3105 SGML reader parses comments and makes them part of the data1 tree.
3107 Added several type casts so that YAZ compiles as C++ code.
3109 ZOOM didn't handle PDU encoding failures properly.
3111 Added more Bib-1 diagnostics (approved extensions).
3113 GNU configure: better check for iconv.
3115 More portable use of accept, getpeername. Check for socklen_t. Use
3116 int/size_t if socklen_t is not defined.
3120 PQF parser rejects bad queries - including those with extra
3121 characters in them. PQF parser used to silently ignore that.
3122 Cleaner API for PQF added, which allows you to get detailed
3123 error information for bad queries (see yaz/pquery.h).
3125 Fixed bug in ZOOM_record_get for type "database".
3127 Implemented mini iconv library supporting conversions between
3128 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3130 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3132 --- 1.8.9 2002/08/20
3134 Fixed ZOOM C record cache so that preferredRecordSyntax and
3135 elementSetName is used to check for already fetched records.
3137 --- 1.8.8 2002/08/02
3139 Added three members in bend_initrequest structure to facilitate
3140 character set negotiation.
3142 Fixed a bug in frontend server that could cause indefinite
3143 loops under rare conditions.
3145 Revised character set utilities (charneg.h) so that encoding
3146 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3148 For PQF, directive @term <type> sets term type for Scan/Search.
3149 Here <type> is general, string, numeric, null. The term type
3150 is inherited - just like @attr.
3152 New call odr_set_charset that sets character set conversion for
3153 international-strings on a ODR stream. Prototype is:
3154 int odr_set_charset(ODR o, const char *to, const char *from);
3155 The InternationalString is still represented as C string in YAZ
3156 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3157 won't). On the protocol level, you can use any encoding.
3159 Support for UNIX sockets in ZOOM.
3161 Solaris recv sometimes returns errno == ENOENT. It is treated as
3162 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3164 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3165 both client and server. Code by Morten Bogeskov.
3167 --- 1.8.7 2002/05/22
3169 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3170 that they can be used directly from Visual Basic. You must recompile
3171 your windows APP if you're using ZOOM.
3173 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3174 Commands "lang" and "charset" sets language and character set respectively.
3175 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3176 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3178 Attributes from multiple CCL fields may be OR'ed rather than merged
3179 using directive "@field or". Fields are still merged by default -
3180 equivalent to "@field merge".
3182 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3185 Fixed bug in zget for parameter ExtendedServicesResponse.
3189 --- 1.8.6 2002/03/25
3191 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3193 Client displays USR.1:SearchResult-1 (hits per term).
3195 Additional Search Info for search in Generic Frontend Server.
3197 Fixed CCL parsing of "field=s".
3199 WIN32 installer - using the excellent NSIS software from nullsoft.
3201 Fixed CCL parsing of "field = - <number>".
3203 Added function yaz_marc_decode that decodes MARC for line mode
3204 display or XML (similar to that used by JZKit).
3206 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3207 Z39.50. But ISO/ILL was, however.
3209 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3210 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3213 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3215 --- 1.8.5 2002/02/03
3217 New YAZ client features: Command completion and new commands:
3218 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3219 Code provided by Jacob Poulsen.
3221 New call oid_trav, that visits all registered OIDs via callback.
3223 Function ZOOM_record_get now returns const char pointer rather than
3224 void pointer. It saves a lot of type casts.
3226 For YAZ client, command "auth" now allows you to set authentication
3227 in IdPass style. It is enabled when three tokens are given - order
3228 is user, group and password.
3230 Fix memory leaks in MARC record handling for ZOOM.
3232 New option for YAZ client, -k <kilobytes> that sets
3233 maximum record size. Similar to -k option for generic frontend
3234 server and yaz-ztest.
3236 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3238 Prefix query parser reports "fail" when bad attribute set is given.
3240 Fix in MARC decoder. Proximity logging. Fix for attribute set
3241 in scan handler for server. Patches by Shigeru Ishida.
3243 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3246 Configure option --with-openssl=<dir> now works when a directory is
3247 specified. Patch provided by Morten Bogeskov.
3249 New option for YAZ client, -u <auth>, that sets authentication.
3251 ZOOM fix: error information was sometimes "missing", since error
3252 was cleared/reset too when it shouldn't.
3254 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3256 --- 1.8.4 2002/01/04
3258 Scan for ZOOM API. New object ZOOM_scanset. New functions
3259 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3260 ZOOM_scanset_destroy.
3262 New ZOOM function, ZOOM_connection_last_event, that returns type
3263 of last event (such as "receive data", "send data", "apdu received",
3266 New ZOOM option, schema, that specifies schema for retrieval.
3268 New CCL feature. Qualifiers can be aliases for one or more
3269 other qualifiers (if more than one is given, OR is used).
3271 ZOOM uses named result sets if target supports it.
3273 Two new YAZ client commands: . (dot, which sources a script of YAZ
3274 client commands), and ! (to execute shell command.). Implemented
3277 Working on Debian packages.
3279 --- 1.8.3 2001/11/19
3281 YAZ client enables named result sets only if target supports it.
3283 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3285 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3286 with key="host" to get same result.
3288 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3289 Function Z3950_resultset_record(s) returns references to records
3290 "owned" by resultset. To become owner use Z3950_record_clone.
3292 Function z_ext_record handles Extended Services. Thanks to
3295 --- 1.8.2 2001/11/12
3297 CCL Parser fix: ignore token comma when dealing with and-lists.
3299 Documentation updates for COMSTACK.
3301 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3302 Changed prototype Z3950_records. For some functions, int parameters
3303 were changed to size_t.
3305 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3308 New MARC decode/display function, marc_display_exl, which properly rejects
3309 non-ISO2709 records. YAZ client uses it.
3311 --- 1.8.1 2001/10/29
3313 Fix bug: local attribute set wasn't set correctly in PQF strings.
3317 * Old Z39.50 codecs no longer supported.
3319 Added ZOOM C binding. See http://zoom.z3950.org/
3321 Renamed states for COMSTACKs to avoid confusion with events.
3323 Implemented cs_look and proper cs_rcvconnect.
3325 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3327 Configure detects POSIX threads on OpenBSD.
3329 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3330 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3332 When error is returned from present handler, non-surrogate diagnostic
3333 is returned in present response (and fetch handler is no longer called).
3335 * Minor adjustments to pquery parser (PQF). Token characters may be
3336 escaped by using backslash (C-style).
3338 PQF parser allows string attribute values to be specified. For @attr,
3339 non-numeric characters after the equal-sign are treated as strings
3340 (e.g. @attr 9=title).
3342 CCL trunction character may be defined (@truncation in file)
3344 * function zget_ExtendedServicesRequest sets waitAction to
3345 waitIfPossible (was wait).
3347 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3350 CCL operator names may be set in field definition files (CCL_bibset).
3351 See ccl/bib1 for an example.
3353 Fixes in ASN.1 compiler for C++ compatibility.
3355 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3356 and "op_or" to avoid conflict with C++.
3358 Fixed problem with GNU readline detection on Redhat 7.0.
3360 Added step-size for Scan backend handler.
3362 Fixed bug that made the frontend server crash when no attribute
3363 set was specified for scan.
3365 Front-end server automatically switches to original working directory
3366 when installed as an NT service. Previously -w had to be specified to
3369 Added extended attributes for retrieval module (data1), so that data1
3370 records carry d1_readXML/SGML attributes. d1_read also supports
3371 null-data rules ( <tag/>)
3373 On UNIX when POSIX threads are available, a separate library libyazthread
3374 is created. Programmers should link with that library and the yaz library
3375 when using threads. The reason for the split was that some applications
3376 on Linux, such as Apache, doesn't work well when using shared objects that
3379 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3380 (or any frontend server) in SSL mode by specifying ssl: followed by
3381 address. Only tested on UNIX.
3383 Added feature for CCL module. Virtual structure s=al or s=ol generates
3384 and-list and or-list respectively instead of phrase search.
3388 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3389 log_mask_str. This was done to avoid name conflicts with other libraries
3390 (such as other PHP extensions).
3392 Added raw OID member for preferred record syntax (request_format_raw)
3393 and returned record syntax (output_format_raw) for backend fetch method.
3395 Config file yaz-config now accepts options so that it returns specific
3396 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3398 Shared library support for UNIX using GNU libtool.
3400 * Modified backend interface. Request/Response struct's replaced by
3401 one read/write C struct. For example bend_fetchrequest and
3402 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3403 Every handler - even search has to be registered in bend_init
3404 handler. This means that the YAZ library no longer refers to
3405 external functions and it makes it possible to make the whole
3406 thing a single DLL/SO.
3408 Added Segment handler for backend server.
3410 Added Zmbol/Zebra administrative functions to YAZ client.
3412 Threaded frontend server on UNIX (when POSIX Threads are available).
3413 Starting the server with option -T enables multi-threading.
3417 Added configure option --enable-comp/disable-comp to control use
3418 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3419 located in sub directory asn.
3421 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3422 in ${exec_prefix}/bin along with the other programs yaz-client and
3425 GNU automake used to maintain makefiles.
3427 Added several OID's.
3429 Changed retrieval module so that we can load records with no abstract
3430 syntax defined. Tagpaths in these records are fully composed of string
3433 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3437 On UNIX, the generated makefile now supports a proper 'make install'.
3438 The prefix can be set via GNU configure to set the install location
3439 (default is /usr/local).
3441 * YAZ programs client and ztest were renamed to yaz-client and
3442 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3443 locations, such as /usr/bin,/usr/local/bin,etc.
3445 * YAZ Header files were moved from include to include/yaz. YAZ Header
3446 files are referred to as include <yaz/log.h> rather than <log.h>.
3447 The YAZ include path (-I ..) is therefore the same as before. Programmers
3448 should update their #include statements or use -Ipath/include/yaz
3449 instead. The main motivation for doing this change is that YAZ header files
3450 can be installed in "standard" locations /usr/include,/usr/local/include
3451 without introducing conflicts, since ALL YAZ header files are stored
3452 in subdirectory yaz (under /usr/include for example).
3454 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3455 rather than project/workspace files. We switched because project files
3456 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3459 Changed name of logging function, logf, to yaz_log, to prevent name
3460 clash with some math-log functions. The YAZ header log.h defines logf
3461 to yaz_log (#define) so there should be no incompatibilities by this
3464 Added bend_start/bend_stop handlers for server. These handler are
3465 called on start/stop of server. For windows they are called whenever
3466 a service is started/stopped.
3468 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3469 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3470 in util/yc.tcl. The auto-generated C code structures are, in a few
3471 cases, incompatible with the old decoders. There are differences in the
3472 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3473 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3474 The preprocessor variable ASN_COMPILED is defined when the compiled
3475 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3476 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3477 wish to use the old encoders/decoders you can specify --disable-yc
3480 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3481 version so that it supports both new - and old version of DB Update
3483 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3484 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3485 change. The name parameter can be set to 0 in which no name is specified
3486 for the construction. The macros odr_implicit and odr_explicit sets name
3487 parameter to zero for the construction involved. New macros
3488 odr_implicit_tag and odr_explicit_tag are similar to the others,
3489 except that a name parameter is added. For programmers' that don't use
3490 ODR they probably only need to change the call to z_APDU and z_External.
3492 Added access control facility by interfacing the TCP wrapper library.
3493 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3494 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3495 name of the daemon and enables the access control as specified in
3496 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3498 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3499 den Dool <H.M.vdnDool@kub.nl>.
3501 Added reference ID parameter to most functions in server API - refer
3502 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3504 Changed name of ccl library to libccl.a (was ccl.a).
3506 Fixed bug in decoder for Explain (Category TargetInfo).
3508 Added support for GNU readline in client. Thanks to Jacob Poulsen
3509 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3511 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3512 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3513 IMPLEMENTATION! This change was made to the development version before
3514 the ZIG decided to retract the amendment. If any users MUST be
3515 compatible with the original Update definition, PLEASE CONTACT US, and
3516 we will include a separate definition corresponding to the old Update
3517 ES. Note that because of the change to the ASN.1 of the
3518 TaskPackageRecordStructure we cannot define a single structure that
3519 will support both versions.
3521 * Added const modifier to buffer parameter for some ODR/BER encoding
3522 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3523 completeWAIS, odr_dumpBER.
3525 Fixed bug in client.c which caused a crash when a scanResponse didn't
3526 contain positionOfTerm.
3528 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3529 * will cause an error in a client if a non-YAZ target sends both a
3530 * list of Scan entries and non-surrogate diagnostics.
3532 Retrieval module enhancements. Tag sets may be typed in the reference
3533 to it. From the .abs-file the "tagset" directive takes a third optional
3534 integer type for the tag set referenced. From a .tag-file the "include"
3535 directive takes a third optional type as well. The old "type" directive
3536 in the tag set itself is still recognized but acts as the default type
3539 Backend interface change. Individual Scan terms returned from bend_scan
3540 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3541 in include/backend.h.
3543 Retrieval module enhancements. Multiple tag sets and attribute sets may
3544 be specified in abstract syntax specs. Revised the error/warning for
3545 logging messages reported by the retrieval module when reading the
3548 Object Identifier system (oid_..) changed. The API is backwards
3549 compatible but the oid-routines now allocates new OID's when needed.
3550 Raw OID's may be specified in oid_getvalbyname.
3552 YAZ now uses GNU configure to generate Makefile(s).
3554 * Minor changes in some of the member names of DeleteResultSetRequest and
3555 DeleteResultSetResponse. See include/proto.h.
3557 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3558 and added member 'languages' in TargetInfo (which was missing).
3560 Changed the way attribute sets are handled in the retrieval
3561 module. These are now cached, just like the abstract syntaxes
3564 Changed YAZ so that it links with compiled ASN.1.
3566 Added Explain-schema definitions and mapping routines. The following
3567 Explain categories have been implemented: AttributeDetails,
3568 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3570 Fixed minor bug in Windows version of Server Library.
3572 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3574 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3576 Added EXTERNAL: UNIverse Resource Report (non-standard).
3578 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3579 ENUMERATED and SET OF.
3581 * Added 'const' to some of the char pointer arguments for the
3582 functions, data1_read_node, data1_getelementbytagname,
3583 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3586 Fixed bug in data1_insert_taggeddata - the last_child member of
3587 parent wasn't initialised.
3589 * Changed data1_read_record and data1_read_node so that the supplied
3590 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3591 doesn't refer to any parts of the "SGML"-buffer.
3593 Fixed bug in server library (Windows version of statserv_remove).
3595 * Changed code so that it compiles as C++. The type definition
3596 of Odr_fun which is a member of Odr_arm was changed. The result is,
3597 that an explicit typecast is needed for the fun pointer when
3598 using Odr_arm - as in:
3599 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3601 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3603 Implemented the new structured date and time definition as approved
3604 by the ZIG. Added schemaId element to the specificTag in Espec-1
3605 (also approved at the last ZIG). Thanks to RVDM.
3607 Added some Object identifiers (RVDM).
3609 Changed the Update Extended Service (RVDM).
3611 Added command "refid" to client which specifies referenceId for
3612 the following requests.
3614 Implemented extended service handling for server. See ztest.c
3615 for an example as well as backend.h. New handlers are registerd
3616 in the Init handler.
3618 * Changed interface for sort in server.
3620 Added new members to statserv_options_block. It allows a server
3621 to read options from another source than just the command line. Thanks
3622 to Charles Woodfield.
3624 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3625 renamed to zboolean. Some C++ compilers complained about the name.
3627 Minor changes to gils.abs. Added index 's' (sort) on title
3628 and date/time-last-modified.
3630 --- 1.4pl2 1998/1/30
3632 Fixed bug in server library regarding inetd mode (-i). This bug
3633 was introduced by release 1.4.
3635 --- 1.4pl1 1998/1/29
3637 Added sort facility in client and backend server interface.
3639 Fixed problem with dependencies in Makefile(s).
3641 Fixed bugs for encoders/decoders of extended services and
3644 Implemented sub-tree feature for schemas. Sub-trees are
3645 referenced in *.abs-files. See explain.abs for an example
3646 of the use of this feature.
3648 Modified bib1.att; local attributes for ANY didn't include
3649 ANY itself (only affects use of the retrieval module).
3651 Fixed bug in plain SGML reader in function data1_read_node:
3652 tags with prefix "var" was incorrectly interpreted as variants.
3654 Added feature "sub-schemas" to enable references to - and definitions
3655 of - group of elements.
3657 * Removed member parent from type data1_element (in data1.h).
3659 Implemented function odr_nullval() that returns the value of
3662 * Removed member num_children from data1_node (in data1.h).
3664 Made NT service interface part of the server library. The
3665 function statserv_main uses the NT service when required and
3666 calls the statserv_start / statserv_close routines.
3668 Routine zget_SearchRequest and zget_PresentRequest fills
3669 resultSetName/Id member with "default" instead of "Default".
3671 Fixed memory leak in server. Request queue member wasn't freed.
3673 Fixed nmem_exit so that memory is freed.
3677 Revised the CCL parser utility to be thread safe.
3679 Added function, oid_ent_to_oid, to replace the function
3680 oid_getoidbyent, which is not thread safe.
3682 * Added nmem_init and nmem_exit to initialize and release
3683 NMEM resources. Function nmem_init should be called once in the
3684 initial thread before NMEM/ODR is used. statserv.c and client.c
3685 have been changed accordingly. The change was necessary to make
3686 NMEM thread safe. The NMEM memory pool is shared amongst threads
3687 in a process. Unix-based applications will still work fine without
3690 Added NT Services interface for the the Z39.50 (statserv) Server.
3691 Refer to the ztest.c source on the usage.
3693 Windows 95/NT port using MSVC5.0. Project files are included in the
3696 * Defined new 'global' handle for the retrieval (data1) system. The
3697 new handled, data1_handle, describes the state of the data1 system.
3698 This handle is passed as first argument to virtually all
3699 data1 related routines. The functions data1_create and data1_destroy
3700 creates and destroys a data1 handle respectively.
3702 Added ODR encode stream member to all backend request structures
3703 init, search, scan etc. This stream should be used to allocate all
3704 memory used for the response when thread safe operation is needed.
3706 Changed the comstack utility, cs_addstr, to be thread safe. The
3707 returned hostname string returned by the function is now part the
3710 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3711 function. The cs_straddr takes a COMSTACK handle as argument, so this
3712 function must be used after cs_create and before bind/connect.
3713 This function is thread safe.
3715 Moved test server to 'ztest' directory - generic server code still
3716 in 'server' directory.
3718 Made prefix query (pquery.c) utility thread safe.
3720 Added new function modifier YAZ_EXPORT to 'export' public DLL
3721 functions when using windows (see include/yconfig.h).
3723 Added definitions to the OID database (util/oid.c) (RVDM).
3725 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3727 Added call to ccl_rpn_delete in client program.
3729 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3730 release of RPN structure.
3732 Added support for C++, headers uses extern "C" for public definitions.
3733 With input from RVDM.
3735 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3736 Thanks to Ronald van der Meer (RVDM).
3738 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3740 Added support for private extensions to the OID database
3741 (oid_setprivateoids()). Thanks to RVDM.
3743 Added optional, physical ANY (key replication)
3745 Fixed null-reference problem in GRS-1 output filter.
3747 Proximity operator added to Prefix Query Format (PQF).
3749 In test client command "base" accepts multiple databases.
3751 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3755 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3757 Smallish bug-fixes in the new encoders/decoders (explain).
3759 Bug fixed in DeleteRequest.
3761 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3763 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3765 Added SOIF syntax (using private OID for now) to retrieval module and client.
3767 Added Update extended service.
3769 Added SearchResult-1 additional info structure.
3771 Added optional CCL (ISO8777) interpreter as separate module. Available
3774 --- 1.2 1996/6/10 (1st anniversary release)
3776 Added Summary record syntax. Lightly tested.
3778 Added OPAC record syntax. Untested.
3780 Added ResourceReport service encoders/decoders. Untested.
3782 Fixed bug in z_Unit - wrong tagging on unitSystem.
3784 Fixed bug in the DiagRecs decoder.
3786 Added options for max PDU size and session timeout to frontend-server.
3788 Added documentation of query-language parsers and other supporting utilities.
3790 [frontend-server] Added Attribute set to the bend_scanrequest API.
3792 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3793 surrogate diagnostics were generated.
3795 [retrieval] Allow multiple local values for attribute.
3797 [retrieval] Allow multiple attributes per element in .abs files. index type.
3799 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3801 --- 1.1pl2 1996/4/10
3803 Minor changes, mostly specific to Zebra's requirements (retrieval)
3807 Repaired bug in frontend server when running multiple listening
3808 endpoints in dynamic mode.
3810 z_External() now won't break if a known, ASN.1 value comes encapsulated
3811 in an octet-string. The value will pass through unmodified in an Odr_oct.
3813 Added a bit of code to the demo client to decode & display
3814 ASN.1-structured records represented in the octet-aligned branch of
3815 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3817 Added z_ext_getentbyref() to the ASN module. Doc updated.
3819 * Completed the SCAN definition in the ASN module. This may break SCAN
3820 code based on older YAZ-versions at compile-time. The fix is easy -
3823 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3824 under the SCAN definition. Remember to initialize this, server-people.
3826 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3827 that this does not extend to ODR and ASN.
3829 Comstack allows insertion of established socket (primarily for
3830 inetd-operation of servers). Doc updated.
3832 Front-end server can now start from the inetd in TCP mode. Doc
3835 --- 1.0pl4 1996/1/24
3839 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3840 the rank and record number.
3842 Adjustments to the frontend server.
3844 Fixed diagnostic BER dumper. It ignored the file argument.
3848 Various changes to retrieval module.
3850 Changed the union discriminators of the protocol files from enums to
3851 ints paired with #defines.
3853 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3856 *Changed operator in the RPN structure to 'roperator', again to avoid a
3859 Fixed problems in Explain decoders/encoders.
3861 --- 1.0pl2 1995/12/6
3863 Memory bug in log module fixed.
3865 --- 1.0pl1 1995/12/5
3867 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3869 Bug in Explain DatabaseInfo module fixed.
3871 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3875 The shift to v1.0 signals that we now consider the *core* functionality
3876 of YAZ reasonably stable (the core being more or less equivalent to
3877 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3878 tested (Explain not at all - though that will happen soonish).
3880 Minor changes to code to support Windows port.
3882 Various minor changes after we're getting to use GRS-1 & co. more.
3884 Added Espec-1 format.
3886 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3887 of the protocol and it cannot be selected when encoding (maps into 'string'
3888 when decoding). Needed to talk to some servers.
3890 Demo client can request simple element set names.
3892 Added Diagnostic Format encoders/decoders.
3894 Added simple Close handling to frontend server (no hooks for resource
3895 reporting yet), and demonstration client.
3897 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3899 --- 1.0b3 1995/08/24
3901 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3902 handled incorrectly when records were requested in the searchResponse. This
3903 will only affect you if you use the frontend-server.
3905 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3906 Test-client will ask for and print GRS1. Ztest will return dummy records
3909 Added Explain encoders/decoders to the service-level API. Untested.
3911 Added Extended Services: Item Order encoders and decoders to the Service-
3912 level API. Untested. We could use a recent copy of the pertinent bits
3913 of the ILL protocol to add those bits.
3915 Added diagnostic format 1 encoders/decoders to the service-level API.
3918 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3919 odr_cons.c, which causes a more correct output.
3921 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3922 was always set to 0 when no records were requested in the searchRequest.
3924 * Added better external-handling. This shouldn't harm old code that
3925 *encodes* externals. It can break code that looks for a
3926 'single-ASN1-type' representation, since those types that are known
3927 are now decoded immediately. Look at the SUTRS sample code in
3928 seshigh.c and client.c. Documentation updated.
3930 Handling of structured records in bend_fetchresponse. Length -1 marks
3931 structured record, type is deduced from format field.
3933 --- 1.0b2 1995/06/27
3934 Fairly quick maintenance release to add SUTRS support.
3936 Fixed handling of SUTRS records in the demonstration client.
3938 * Added format field to the bend_fetchrequest and bend_fetchresponce
3939 structures of the backend API (frontend server). When the record is
3940 returned, the value of the format field is mapped to an OID. The
3941 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3942 of the record. The special value VAL_NONE in the bend_request means
3943 that no specific format was requested by the client. Documentation
3944 updated accordingly. Test server (ztest) will return a fixed dummy
3945 SUTRS record if your client requests SUTRS.
3947 Documentation updated accordingly.
3949 You can now set external libraries and RANLIB support in the top-level
3953 First public release.
