3 Windows installer of YAZ includes YAZ4J as a component.
5 CQL: allow "extra terms" again, by default. Thus, the CQL parser
6 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
7 and earlier. CQL parser may operate in strict mode where queries
8 not conforming to the standard BNF are rejected (syntax error).
9 Whether the CQL parser operates in strict mode is controlled with
10 cql_parser_strict . Strict mode enabled with option -S for utilities
11 cql2pqf and cql2xcql .
13 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
17 New charset, MARC-8c, which is like MARC-8 but allows control characters
18 0x01 through 0x1F, except ESC to be passed through verbatim.
20 Fix a problem with duplicate sub field character in MARC output. Problem
21 happened only when output was MARC-8 encoded.
25 yaz-ztest: Use hash for fake hit count. Before, random number was used.
26 This is problematic for unit tests using yaz-ztest. This patch also makes
27 a hash for CQL queries. For RPN, any term with a leading digit will be
28 treated as pseudu hit count (to force any particular hit count by a client).
30 yaz-ztest: return unique MARC dummy records. Beyond record offset
31 24, the author surname is patched with offset to make all records
34 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
35 on system wide default (/proc/sys/net/ipv6/bindv6only).
36 @4 binds to IPV4 only. @6 binds to IPV6 only.
38 Update CQL API documentation a bit
40 CQL: don't accept extra terms for queries. Makes the CQL parser
41 stricly conformant to the standard.
45 GFS: scan handler gets extra_args from request and may return extra
46 response data . That's for SRU only.
48 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
52 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
54 OPACXML: sync spelling of availabilityDate in XML to that of Schema
55 opaxxml.xsd. The schema had the correct spelling of this member always.
56 The ASN.1 was mis-spelled and still is (API change) - we are
57 not changing this. However, the OPAC to XML conversion had yet
60 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
63 New function, z_ext_record_oid_nmem, which is similar to
64 z_ext_record_oid but takes NMEM rather than ODR
68 ICU: New conversion element 'join' which joins tokens into one
69 with a custom character given by rule attribute.
73 New GFS search member: present_number. This is a hint to the
74 search handler how many records are going to be fetched immediately
75 following search. There's no guarantee that it's going to be the case,
76 since it depends on hit count (for Z39.50 piggyback) and whether errors
79 Make a few functions static (private). The functions getbyte_stream,
80 ungetbyte_stream and yaz_gets are now private. They were never declared
83 yaz-marcdump: exit(5) for serious decoding errors
85 ISO2709 decoding: be more picky WRT header
87 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
88 was only used as to indicate that next-result-set-position should be
90 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
91 Based on patch from Ashley Sanders.
93 Make some functions static/private in PQF parsing. Those functions were
94 never declared in a public header and so should not be in use by
95 applications based on YAZ.
99 ZOOM: special options to control APDU logging.
100 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
101 logging of APDUs until "saveAPDU" option is set again. If logging is
102 already enabled the effect is that current APDU buffer is cleared.
103 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
104 logging (default behavior on new connection).
105 The APDUs sent/received can be obtained by using
106 Using ZOOM_connection_option_get(c, "APDU") or
107 ZOOM_connection_option_getl(c, "APDU", &l).
109 GFS: relay implementation_version from backend
110 From 3.0.40 and later, implementation_version from backend was
111 not used in init response at all.
113 --- 4.2.46 2012/11/15
115 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
116 mode at all. Probably never did.
118 Make a new version of ztest.pem that, at least, is not expired.
120 --- 4.2.45 2012/11/13
122 Fix description of CCL directive 'case'.
124 More tight checking of form arguments (yaz_uri_to_array). Makes
125 YAZ better at rejecting big and/or bad POSTs.
127 SRU decoding does not report more than up to 10 invalid arguments.
129 rpn2cql: less quotes in generated terms. Semantics unchanged, but
130 it's prettier this way.
132 --- 4.2.44 2012/10/25
134 New utility yaz_decode_init_diag. Defined in proto.h.
136 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
137 given for unix local socket.
138 The COMSTACK string for doing so is:
141 unix:/myfile:tcp:localhost:9999/mybase
142 unix:/myfile:localhost:9999/mybase
143 unix:/myfile:http://fakehost/mybase
145 debian: Use dpkg-buildflags in build process.
147 --- 4.2.43 2012/10/19
149 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
150 global's SRU service uses a recordPosition scheme starting from zero.
151 First record's position should be one
152 according to the standard.
154 --- 4.2.42 2012/10/18
156 Allow more namespaces for SRU. This is to allow, for example, an
157 incorrect namespace returned from server
158 http://services.igi-global.com/sru .
160 Minor fixes for compilation on Windows.
162 --- 4.2.41 2012/10/11
164 daemon: log total number of bad signals from child on stop so that it
165 is more easy to spot problems with child worker processes.
167 retrieval: empty backend name attribute omits element set
168 from being used in retrieval.
170 --- 4.2.40 2012/10/04
172 Implement Solr sort strategy "solr", similar to sru11 sorting.
173 This will implement the correct parameters on Solr requst to do
176 --- 4.2.39 2012/09/28
178 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
181 MARC: Extra/missing indicator handled for MARCXML.
182 The indicator length is given in header and is the same for the
183 whole record. If attributes ind1, ind2 are missing, then content
184 character defaults to blank. Extra indicator attributes (beyond)
185 indicator length are treated as an error.
187 Reformat: delete trailing whitespace
189 --- 4.2.38 2012/09/17
191 MARC: fix non-ASCII characters for leader. This is to ensure we can
192 generate XML in UTF-8.
194 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
195 in one node with structure word.
197 --- 4.2.37 2012/09/04
199 yaz-json-parse: JSON output may be pretty printed by using option
202 Increase default value of max message for Z39.50 Init for GFS, ZOOM
203 and yaz-client. Old value was 1 MB. New value is 64 MB.
205 --- 4.2.36 2012/08/22
207 yaz-client: don't display bogus records from SRU servers. Some SRU servers
208 return more records than given by *maximumRecords*. Skipping those in
211 record_render: simplify buffer return handling and fix at least one bad
212 memory reference, that broke the test_embed_record sometimes.
214 Allow http://user:pass@host notation for yaz_url_exec.
216 zoomsh: allow shell command to be executed. Via the system(3) call.
218 yaz_poll: Allow num_fds == 0
220 yaz-client: fix bad encoding of "itemorder item". The itemorder
221 item <no> - command forgot to use length of encoded Item Request
222 package. Error present since YAZ 3.
224 yaz-ztest: fix bad usage of session handle. Bug was introduced when
225 result sets were saved (271a9c83).
227 SRU recordPacking: guess record packing in response rather than looking
228 at the recordPacking element which, OF COURSE, changed semantics in SRU
231 Decode SRU 2.0 responses. The official namespace for responses, according
232 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
233 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
234 nature.com's server, however, usee namespace
235 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
236 we are now using a glob-expr to match up the namespace. ZOOM C and
237 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
238 I can not find a single real example showing the "real" namespace in
239 the documentation from OASIS. The namespace for requests is different
240 from responses, but this is not added to YAZ yet, when we don't encode
243 --- 4.2.35 2012/06/26
245 zoom/record_render: add support for Base64 decoding fo MARC records
246 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
247 which will decode base64 + ISO2709 marc-8 encoded material from text node
250 --- 4.2.34 2012/06/07
252 Add missing definitions ZOOM_resultset_get_facet_field_by_index
253 and ZOOM_resultset_facets_names.
255 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
258 Change APDU dump printing to avoid long leading blanks. For levels 16
259 or larger the level is shown and the indentation is truncated but
260 recursed with modula 8. This makes it still reasonable easy to read
261 - even for nested BER dumps.
263 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
264 return 0 (incomplete package) in case where the BER package was
265 considered too nested (return value of -2).
267 dumpber: lines of level 15 are not indented further. Two spaces per
268 indentation; indentation 15 or more is indented to a fixed indentation
269 and augmented with a level=<no> indication.
271 zoomsh: increase max size of command+args
273 GFS: No limit in RPN buf size in CQL to RPN conversion.
275 --- 4.2.33 2012/05/09
277 New function for daemon utility, yaz_daemon_stop .
279 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
281 --- 4.2.32 2012/04/25
283 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
284 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
286 --- 4.2.31 2012/04/23
288 YAZ daemon utility relays SIGUSR1 to child process.
290 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
291 would result in en empty database list - which in turn would result in
292 encoding failure for search.
294 Fix reading beyond string in yaz_sort_spec.
296 --- 4.2.30 2012/04/11
298 Add two new SRU diagnostics:
299 236: Access to specified database denied
300 1015: Init/AC: Maximum number of simultaneous sessions for Userid
302 Document the very useful ZOOM-C option "apdulog".
304 CQL to RPN: term may be passed through verbatim. This is enabled with
305 truncation.cql . The assumption being that the term is already CQL.
307 --- 4.2.29 2012/03/20
309 record_conv: leader spec may be given for marc element.
310 The leader spec is given as attribute leaderspec for element marc.
311 For example to convert a MARC21 record from MARC-8 to UTF-8:
312 <marc inputformat="marc" outputformat="marc"
313 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
315 record_conv: allow user-XSLT params. For example:
316 <xslt stylesheet="MARC21slim2DC.xsl">
317 <param name="myparameter" value="myvalue"/>
318 <param name="otherparameter" value="othervalue"/>
321 record_conv: fix error handling for missing marc charsets.
323 CQL: fix extra terms in wrong order.
325 --- 4.2.28 2012/03/06
327 record_conv: modify new API for conversion types. The conversion types
328 may be passed in new functions yaz_record_conv_configure_t and
329 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
331 Avoid mixed statement/variable declare; fixes compilation with Visual
334 --- 4.2.27 2012/02/28
336 Add non-standard SRU diagnostic: 235: "Database does not exist".
337 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
338 Update SRU to Bib-1 diagnostic maps accordingly.
340 CCL: add two new diagnostics for unsupported masking. The new
341 diagnostics are: "Embedded truncation not supported" and
342 "Single charcacter mask not supported".
344 --- 4.2.26 2012/02/23
346 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
348 --- 4.2.25 2012/01/11
350 Build YAZ for Ubuntu Oneiric.
352 CCL: allow parantheses for proximity operands. For example CCL query
353 (a) % (b) is now allowed.
355 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
356 marked dead, rather then being destroyed. If not, the session memory is
357 being free'd before the search/scan handler is finished. Also destroy
358 'request' memory in request_release rather than in various places,
359 which resulted in leaks from time to time.
361 --- 4.2.24 2011/12/21
363 cql_sortby_to_sortkeys: honor sort prefix.
365 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
366 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
367 The rpn2cql family of functions now always returns quoted CQL terms.
369 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
371 --- 4.2.23 2011/12/15
373 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
374 sequence is treated as one. For example, &&a=b&&&c& is identical to
377 --- 4.2.22 2011/12/05
379 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
380 APDUs for a connection to a WRBUF.
382 --- 4.2.21 2011/11/23
384 Fix cql_sortby_to_sortkeys. Completely broken before.
386 Make CCL's @truncation work again.
388 --- 4.2.20 2011/11/09
390 New ZOOM connection setting: tproxy. It's like proxy, but does not
391 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
392 to set resolved address + port for a connection outside ZOOM itself.
394 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
396 --- 4.2.19 2011/11/07
398 Fix uninitialized variable in Solr spell support (could cause SEGV
399 for SRU response decoding).
401 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
402 back-end's addinfo through into the ZOOM response addinfo.
404 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
405 they are separated by a colon and a space rather than simply
408 --- 4.2.18 2011/10/28
410 Add support for Solr spell-checking/suggestions through ZOOM.
411 If a Solr target has been configured correctly for spelling-checking
412 and suggestions, these will now be returned on the ResultSet option
413 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
415 --- 4.2.17 2011/09/28
417 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
418 with a flag whether to substitute escape sequences or not.
420 --- 4.2.16 2011/09/22
422 Fix nmem_strsplit_escape to substitute escape char properly.
424 New option for zoomsh -e , which makes it abort on first error and
425 return process exit code to indicate success/failure.
427 YAZ options utility supports special option -- which makes all it treat
428 all following arguments as non-options.
430 --- 4.2.15 2011/09/16
432 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
433 searched if absolute filename is given.
435 Fix conv_xslt() error-reporting when stylesheet is not found.
436 (The value of fullpath is meaningless in this situation.)
438 --- 4.2.14 2011/09/07
440 Fix problem in CQL sort node creation: un-initialized memory.
442 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
443 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
444 CQL sortby depending on whether Type-1 or CQL is actually sent to the
447 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
448 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
450 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
451 will make it possible to use both single-character mask (#) and wildcard (?)
452 in CCL . Throw diagnostic for left truncation because that is not supported
455 --- 4.2.13 2011/09/01
457 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
458 cases using escapes (\-sequences) and masking.
460 PQF parse fix: A trailing backslash followed by end-of-string (\0)
461 would result in a read one byte beyond string.
463 rpn2ccl may use Z39.50 masking for terms (t=z).
465 ICU check fix. Don't include library -lCrun on Solaris, unless present.
467 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
468 not --cppflags (which seeems like an error in icu-config).
470 --- 4.2.12 2011/08/27 RPM package only
472 cql2ccl: fix conversion of terms: operator characters were not
475 --- 4.2.11 2011/08/25 RPM package only
477 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
478 CCL parser will map both # and ? to their regular expression
479 quivalents (. and .*).
481 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
482 of reserved CQL characters.
484 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
485 is, so that they are passed through.
487 --- 4.2.10 2011/08/24
489 ZOOM SRU mode: more aggressive re-connect.
491 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
492 made available as a utility function, declared in <yaz/logrpn.h>
494 rpn2cql_structure() supports proximity nodes (except that the Type-1
495 proximity node's "exclusion" binary is ignored, as there is no way to
496 express that in CQL). Fixes bug #4564.
500 Fix SEGV that could occur if set command of zoomsh was given without
501 value (2nd argument).
503 Fix SEGV that could occur if unsupported transport was given for
504 COMSTACK - say https (when SSL was unavailable).
506 Build yaz-url on Windows too.
510 New utility to get web content. Header is url.h. A command line tool
511 yaz-url is part of the distribution and packages.
513 Fixes for SSL COMSTACK (when gnutls is in use).
515 New functions yaz_base64{encode,decode}. Header is base64.h.
519 ZOOM C includes HTTP response buffer as additional info if it fails
520 to decode the SRU response.
522 Make wrbuf_json_puts available.
526 zoom: throw diagnostic for invalid value for option "sru". Before a
527 bad SRU request was sent.
529 Adding new utility wrbuf_vp_puts.
531 Add cclxmlconfig.obj to win/makefile. It was missing completely.
535 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
536 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
537 redirect was used at the same time.
539 MARC line mode decoding: be less picky about length given - first
540 5 digits of header that is.
542 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
544 Changes to decoding of SRU records: a record with recordPacking=xml is
545 modified with a new root element <yaz_record> if the recordData contains
546 multiple children elements. This is to make the record XML parseable
549 RPN to Solr conversion: encode special characters.
551 Generic Frontend Server: fix uinitialized member, stepSize.
555 Fix a bug in SRU decoding of records.. The database records stored
556 had un-initialized memory, but it would only be seen with yaz_record_render
557 and type_spec="ext" .
559 Fix a bug in ccl_qual_dup introduced in 4.2.3.
563 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
567 Add new utilities to convert from CQL to CCL . These utilities have
568 prefix cql_to_ccl defined in cql.h.
570 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
571 lead to memory heap corruptions when ICU utilities were in use.
575 Make compilation work without Libxml2.
577 yaz-client: remove redundant blanks in display of searchResult-1 term
582 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
583 resulting CQL node (tree) in a new node CQL_NODE_SORT.
585 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
586 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
587 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
588 Note that the CQL sortby spec is only converted when the GFS is already
589 converting from CQL to RPN (cql2rpn element).
591 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
592 specify whether to collapse delimitors or not. The existing nmem_strsplit
593 do collapse (collapse parameter = 1).
595 Windows installer: For NSIS, set InstallDir depending on x86/x64.
597 Rename internal func yaz_use_attribute_create. While non-static, this
598 function is not declared in a public header.
602 Add -lCrun when linking with ICU on Solaris.
604 More quicks character set conversions for OPAC records.
608 fix problem with record_render: records were converted (character set
609 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
613 SRU: add methods for handling DADS SRU-proxy facets.
615 Separate OPAC record character set for ZOOM_record. yaz_record_render
616 allows a character set given as charset=from/opacfrom,to where 'from' is
617 the character set of a bibliographic record, 'opacfrom' is character set
618 of OPAC record and 'to' is the target character set.
622 yaz-client: show may XML format records. Command show followed by 'format'
623 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
626 src/stemmer.c: Avoid using unnamed union. It is not supported by some
629 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
632 Update yaz.spec to operate on both SLES11 / Centos 5.5.
634 RPM: Release includes 'indexdata' name. Use indexdata in release name so
635 this package can be distinguished from other vendors.
637 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
638 as determined by configure
640 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
642 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
643 returns no error and no record, the present request is considered
644 partial (only a subset of the records could be returned by backend), and
645 so it is appropriate to set Present Status to partial-4.
649 Move yaz-config man pages to section 1.
651 More documentation about Solr.
653 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
654 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
655 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
656 peers on some Linux systems. However, in general that does not work
657 so YAZ can not rely on that to work. Debian changed behavior in this
658 respect from Debian lenny to Debian squeeze (still testing as of Oct
660 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
662 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
666 Fix yaz-config output: echo_source not set correctly by configure.
670 Solr Web Service support for yaz-client and ZOOM.
672 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
674 --- 4.0.12 2010/08/17
676 Z39.50 facet support. Facet specifications are passed for search in
677 other-information with ASN.1 as defined in facet.asn and OID
678 .10.1000.81.5 . Facets are expressed as an Attribute list as known
679 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
680 3 is limit (number of entries to get in response). yaz-ztest returns
681 dummy facets if a client asks for them.
683 --- 4.0.11 2010/07/09
685 CCL fixes: bug 2895 and bug 3539.
687 GR1-display: add comma in display - was removed by mistake in
690 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
692 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
694 --- 4.0.10 2010/06/18
696 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
697 result set from a connection. The result set will be on its own
698 thereafter; no operations on it will perform retrievals from a target.
699 Only cached copies are returned.
701 ZOOM C:fix case for HTTP servers responding with Connection:close.
702 Ensure that if there is a current task it is resumed (like fetching
703 more records in a result set) . Bug #3484.
705 PQF parser: use odr_atoi for Odr_int (not atoi)
707 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
708 values that contain any non-digits are treated as string attributes
709 (previously decoding only checked for leading character ([0-9]). PQF
710 encoding: attribute string values are not surrounded by double-quotes.
714 New utility for managing threads - thread_create.h.
716 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
717 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
718 but YAZ' implementation do.
720 Fixes for yaz_cond-functions on Windows 7.
722 DLL export more symbols.
724 zoomsh: show record do NOT render opac.
726 Remove *.la files from Debian and RPM packages.
730 Debian package libyaz-dev depends on libgnutls-dev again (was
731 removed in YAZ 4.0.6, but due to Libtool it is still needed
732 even though yaz-config do not list libgnutls libs).
734 ZOOM: Use only one WRBUF for returning string results for
735 ZOOM_resultset. Reduces memory usage for ZOOM in general.
737 ZOOM: ZOOM_connection do not use a shared pointer to
738 ZOOM_resultset after ZOOM_resultset is destructed by
739 user. Reverts to YAZ 4.0.4 behavior.
743 record-conv: fix problem with at least one XSL conversion -
744 due to probably incorrect usage of XML XSL documents.
748 Fix yaz-config for static mode and the use of SSL (gnutls).
752 Forward decl timeval struct in mutex.h and gettimeofday.h.
754 yaz-config: fix 'static' mode linking.
758 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
759 are wrappers for pthreads or Windows. For Windows these are put in
760 a separate DLL: yaz_cond4.
762 libyaz.la (whole source) is compiled with thread. If thread support
763 is enabled enabled, all source of YAZ is compiled with treading support.
764 This allows core utilities such as yaz_log to use thread facilities.
765 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
766 thread utilities. This commit moves mutex utilities (mutex.c) from
767 libyaz_server.la to libyaz.la.
769 yaz-json-parse displays leading text until error.
773 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
774 patch from Giannis Kosmas.
776 SRU: no longer URL encode SRU database. The URL for an SRU server is
777 a URL and such is alreeady encoded - at least when given with leading
778 http:// or https://. This reverts behavior to YAZ 3.0.50.
780 Support for new MARC XML notation TurboMARC which like MARCXML is a
781 complete representation of MARC/ISO2709.. This one, however, is more
782 compact and allows for faster processing with XSLT. TurboMARC can be
783 used in the marcdisp.h API, from the yaz-marcdump utility and from
786 yaz-ztest can be configured - via the database - to perform certain
787 delays when it performs operations search, present and single record
788 fetch. This allows testers to make yaz-ztest act as a real or even slow
789 Z39.50 server. Refer to the yaz-ztest man pages for details.
793 wrbuf_destroy allows NULL WRBUF passed to it.
795 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
797 Add ZOOM_connection_close.
799 No fixed size buffers for ZOOM shell - bug #3257.
801 tstodr: make it work on s390 platform.
803 New icu iterator-functions. The new icu_iter-functions makes it possible
804 to use ICU chains from many threads.
806 yaz-client: better syntax check for show command.
810 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
813 New simple local-file XML include facility which allows file glob-patterns.
814 Refer to yaz/xml_include.h.
816 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
819 ZOOM_record_get supports new parameter "format" which makes it format XML
822 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
823 JSONText in ECMA-262) is JSONValue, not JSONObject.
827 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
828 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
830 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
831 POSIX/Unix builds .so with major version 4.
833 Remove old LOG_-defines from log.h. They have been obsolete and
834 undefined by default for the last 5 years.
836 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
838 GFS: Remove socket (int *fd) from search_rr handler. The socket
839 descriptor ptr is a facility that allowed a search handler to supply
840 a socket which would serve as a callback - when search was complete.
841 This facility has now been in use for years.
843 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
844 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
845 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
846 returns 'const char *' rather than 'char *. The returned string is
847 read-only and should not be modified by applications. COMSTACK cs_close is
848 now a void function - it no longer returns int. No applications check for
849 the value and the implementations has always returned 0.
851 ZOOM: use size_t for scan hit counts and str size. Functions
852 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
853 occ (hit count) and len (string length) are now of type size_t pointer
854 rather than int pointer. This is to be able to represent large hit counts
855 and to also just to use the proper type for string length (strlen result).
857 New JSON parser. Refer to include/yaz/json.h .
859 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
860 Used to be int in some cases. Many wrbuf_-functions used to return an int
861 indicating some length.. These return values were never used. And so they
864 ODR: odr_malloc, odr_total now takes size_t for size.
866 clone_z_type: fix leak; occurred for encoding failures.
868 --- 3.0.52 2009/12/03
870 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
871 bug was introduced in 3.0.51.
873 --- 3.0.51 2009/12/02
875 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
877 tcpip comstack: fix leak for getaddrinfo.
879 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
880 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
881 Decoding of SRU "path" database is performed by private function
882 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
883 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
885 yaz-client: honor base command for SRU. Change when database setting
886 is applied for SRU and ensure it is kept when a connection is reset.
887 Change also the way errors are displayed or SRU (decoding of packages).
889 --- 3.0.50 2009/11/02
891 Add support for extra request / response data for SRU codecs and GFS.
892 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
893 for extra data response buffer and length. For the GFS, both request
894 and response data (XML) is carried in extra_args and extra_response_data
895 for the search handler. Patch by Ko van der Sloot.
897 ZOOM: For queries that cannot be converted to the specified rpnCharset,
898 ZOOM now returns a diagnostic on the client-side ('invalid query' /
899 10010). This fixes bug #2113.
901 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
902 cmdfile included a 'quit' command that would result in a memory violation.
904 --- 3.0.49 2009/10/01
906 Make a number of functions defined in xmlquery.c static. These have
907 never been declared in a public header file (yaz/xmlquery.h) and was
908 made public by mistake.
910 Improve speed of character conversions (iconv utilities). This makes
911 conversions from MARC-8 faster.
913 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
914 unless type desired is "raw". This will prevent type "xml" from
915 returning ISO2709 .. Which obviously can not be XML parsed.
917 Fix memory leak in ZOOM that would occur if option apdulog was used
918 on a re-used connection.
920 Frontend server logs HTTP requests.
922 Frontend server now sends Z39.50 close when it times out (sesssion has
923 been idle for too long). Versions 2.0.30 and earlier also sent close.
924 But due to a mistake this was disabled in all versions after that, i.e.
925 the server would just close the socket immediately.
927 yaz-client emits a better message when receiving an unrecognised
928 userInformationField.
930 Skip zero-length subfields when decoding ISO2709. This rare case happens
931 if a record has two FS characters in a sequence. Without this patch
932 there would be a reference beyond char array in using_code_len fragments
935 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
937 --- 3.0.48 2009/08/28
939 The show command offered by the zoomsh command now takes a 3d optional
940 parameter type which is what is passed to ZOOM_record. If the type
941 argument is omitted, "render" is used.
943 RPN to CQL conv may use USE string attributes (bug #2978).
945 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
947 --- 3.0.47 2009/07/08
949 Function yaz_xml2query allows a diagnostic element in the PQF XML
950 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
951 code and additional info respectively.
953 The BER BOOLEAN is now the integral type Odr_bool which still happens
954 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
955 typedef'd to Odr_int. This is still an integral 'int', but it may be
956 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
957 ASN-1 compiler as well as programs has been updated to use the new types.
959 --- 3.0.46 2009/06/08
961 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
962 only the bibliographic record was rendered. For type=opac, an OPAC
963 record is only returned if it is present.
965 iconv: small fix for encoding of advancegreek.
967 yaz-client: avoid double display of SRU/SRW records (bug #2798).
969 yaz-client: option auto_reconnect=on really reconnects.
971 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
973 server: avoid null ptr ref for for yaz_poll errors.
975 build: fix RPM build for RHEL 5.3.
977 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
979 --- 3.0.45 2009/03/31
981 Fixed bug #2709: TCP connect returns Invalid argument.
983 Fixed compilation for mingw.
985 Honor charset for raw records (ZOOM_record_get).
987 Fixed use of errno for threaded mode that was seen on Solaris 10.
989 Fixed argument passing with blanks in value for Windows Service.
991 Disable YAZ' own log rotate by default (no 1 GB limit).
992 The variable l_max_size which specifies the log file limit is set to 0
993 (DISABLED): This is due to the fact that YAZ is most often deployed using
994 logrotate. Also YAZ can not perform log rotate because of unsufficient
995 permissions (setuid).
997 --- 3.0.44 2009/02/17
999 List supported encodings in man page for yaz-iconv.
1001 Fixed missing SSL libs for --libs output
1003 Re-established OID record syntax application-xml. Nobody should use it
1004 but we don't want to change soname because of this symbol being absent.
1006 --- 3.0.42 2009/02/02
1008 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1010 Added member named_result_sets for init handler struct for the GFS. This
1011 allows a server to disable named result sets.
1013 Removed OID record syntax application-xml.
1015 Added support for rule-based transliterator for ICU wrapper of YAZ.
1017 Fixed bug #1902: yaz-icu XML output.
1019 Make YAZ checks Emacs friendly.
1021 BITSTRING value shows value. Bug #2346.
1023 ISO2709 decoding: skip control characters from indicator data.
1025 Omit sort key by default in yaz-icu's output.
1027 Allow combined single char options (again) for YAZ' options function.
1029 Utility yaz-marcdump got option to display YAZ version (-V).
1031 Allow YAZ to use ICU 3.4.
1033 Added new ICU test case which illustrates removal of diacritics.
1035 --- 3.0.41 2008/12/29
1037 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1039 --- 3.0.40 2008/12/29
1041 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1044 Fixed bug #2352: yaz-marcdump crashes for certain record.
1046 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1048 Added support for Danmarc2 to UTF-8 conversion.
1050 Added support for ISO5426 to UTF-8 conversion.
1052 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1053 implementation version.
1055 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1057 --- 3.0.38 2008/11/10
1059 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1060 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1062 ZOOM C now interprets databaseName option for ZOOM connection as path
1065 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1067 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1069 Dummy Libxml2 types no longer defined in headers of YAZ'.
1071 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1074 --- 3.0.36 2008/09/26
1076 Various ODR chapter fixes.
1078 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1080 Added missing source for Windows compilation, mutex.c.
1082 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1084 For SRU connections in ZOOM all records up to "count" are now fetched.
1086 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1087 in Windows due to bad error handling for Libxml2.
1089 Added facility for sending arbitrary records (ASN.1 any) using
1090 ZOOM C's Extended service update. Patch by Sam Reynolds.
1092 New options for ZOOM C's connection, logapdu which makes ZOOM log
1095 --- 3.0.34 2008/06/18
1097 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1099 --- 3.0.32 2008/06/12
1101 Fixed memory violation that could occur when decoding UTF-8. This bug
1102 was only present in 3.0.30 of YAZ.
1104 --- 3.0.30 2008/06/06
1106 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1107 GNU TLS is used by default (if found).
1109 yaz-ztest returns OPAC records if a client asks for OPAC.
1111 Improved speed of MARC-8 encoding.
1113 Added support for lossy and loss-less MARC-8 encoding.
1115 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1117 Added new Windows Service wrapper (sc).
1119 yaz-client's itemorder command may now send a file.
1121 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1123 Added new function yaz_log_xml_errors.
1125 Allow (but warn) unknown XML attributes in MARCXML parsing.
1127 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1129 The UTF-8 to MARC-8 conversion now uses a different set of characters
1130 for Greek symbols. Bug #2120.
1132 --- 3.0.26 2008/02/21
1134 Added yaz_daemon (daemon.h).
1136 Fixed bug #2068: pkg-config trouble
1138 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1140 --- 3.0.24 2008/01/28
1142 Document --with-xml2 option.
1144 Added OPAC XML XSD (etc/opacxml.xsd).
1146 Allow glob mask for name attribute in retrieval element for the
1147 generic frontend server's retrieval facility.
1149 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1150 except POLLIN/POLLOUT.
1152 Fixed error handling in cs_listen. Bug #2037.
1154 --- 3.0.22 2008/01/20
1156 Fixed version in yaz/yaz-version.h.
1158 Fixed bug #2027: Crash when closing connection.
1160 Changed configure so that ICU support is only enabled if only ICU
1161 and Libxml2 is available (because the ICU chain is XML based).
1163 --- 3.0.20 2008/01/15
1165 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1166 is built. Only this DLL depends on the ICU runtime.
1168 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1169 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1171 Changed license of CCL module to 'Revised BSD'. After consultation with
1172 remaining members of the original EUROPAGATE consortium, we are re-issuing
1173 the CCL module without a separate license. The software was developed by
1174 Index Data as part of a research project. The special license was included
1175 to help feed usage information back to the project consortium to support
1176 project evaluation. At this time, the project consortium has long-since
1177 disbanded, and the majority of the original principals have retired. At the
1178 same time, we have significantly modified the software during the following
1179 years, to the point where very practically no original code remains. To
1180 simplify re-use of the software, we have contacted those members of the
1181 consortium who could be reached, and agreed to re-issue the module as a
1182 proper part of the YAZ package.
1184 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1186 CQL closer to being version 1.2 compliant. CQL also allows free-form
1187 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1190 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1191 bug could make Extended services handling crash in the ZOOM layer. This
1192 bug was only present in YAZ 3.0.18.
1194 --- 3.0.18 2007/12/19
1196 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1199 yaz-marcdump reads and writes collection wrapped records.
1201 Handle OPAC for record conversion module.
1203 Fixes for ICU wrapper.
1205 Allow ICU libs to be controlled with --with-icu .
1207 --- 3.0.16 2007/11/12
1209 Added yaz_poll which is a wrapper for select/poll. When poll is available
1210 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1211 sockets to be in use.
1213 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1214 functionality through an XML based configuration (ICU chain). This system
1215 is useful for search facilities such as Pazpar2 and Zebra that needs to
1216 perform tokenization of indexed material. The ICU code in a separate
1217 library libyaz3_icu.a.
1219 Added HTTP tunnel facility for COMSTACK, bug #1752.
1220 This is a facility that allows a Web proxy, such as squid, to tunnel
1221 Z39.50 traffic. This facility is "transparent" to must applications
1222 using YAZ. It's enabled by using pseudo transport connect: followed by
1223 the proxy address, followed by command, then follwed by he regular
1224 "virtual" addresss. For example,
1225 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1227 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1229 --- 3.0.14 2007/09/21
1231 Fixed bad memory reference in ZOOM_record - cuased by member not being
1232 initialized. This was a problem only in YAZ 3.0.12.
1234 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1235 fields were not removed.
1237 Changed the way C code is generated from codetables.xml. Made a MARC-8
1238 conversion trie for each characterSet section rather than codeTable.
1239 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1240 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1242 --- 3.0.12 2007/09/12
1244 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1245 from ZOOM_record_error).
1247 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1249 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1251 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1253 Better SRW-to-Bib-1 diagnostic mapping.
1255 ZOOM C and yaz-client announces SRU version 1.2 by default.
1257 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1260 Fixed in yaz_sru_decode to allow other version than 1.1.
1262 --- 3.0.10 2007/08/22
1264 Added support for SRU scan for ZOOM.
1266 Added support for the use of the older versions or Extended Service
1267 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1268 set to the version , 1=first, 2=second, 3=third. The third version is
1269 what ZOOM C has used so far. And that, obviously, is the default.
1271 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1272 therefore in Zebra and in SimpleServer-based applications). The new
1273 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1274 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1275 which is passed into the back-end search callback function.
1277 Added support for HTTP Basic authentication in clients: the SRU/W
1278 codec encodes the username/password elements of the PDU structure
1279 appropriately, and these may be set using the "user" and "password"
1280 options in ZOOM-C applications (the same options that are used for
1281 Z39.50 authentication).
1283 --- 3.0.8 2007/06/25
1285 Fixed bug #1208: SSL appears to be broken in ZOOM.
1287 Fixed bug #1206: Libxml2 include path weirdness.
1289 Added oid_name_to_dotstring.
1291 Allow elementSetName to be specified for ZOOM C record update.
1293 Allow waitAction to be specified for ZOOM C based for Extended Services.
1295 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1296 syntax OID. Bug introduced in YAZ 3 series.
1298 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1300 --- 3.0.6 2007/06/06
1302 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1303 directory. yaz-client now reads commands from file given by option -f
1304 if specified; then tries to read .yazclientrc in current directory.
1305 Failing that, it reads .yazclientrc from user's home directory.
1307 Added support for correlationInfo Note and ID for Record Update via
1310 Added yaz-client command querycharset which specifies character set for
1311 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1312 (termListAndStartPoint).
1314 Charset ISO5428:1984 is an alias for ISO5428-1984.
1316 Implemented a way to perform scan in a result set using Z39.50. This
1317 is achieved by attaching the result set name in the characterInfo
1318 (type InternationalString) of OtherInformation in the Scan Request PDU.
1319 The result set is identified in the otherinformation by the new OID:
1320 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1321 This allows for scan in result set and faceted search . Zebra did some
1322 of this in the APT term using attribute type 8 and value being result
1323 set. Using the OtherInformation approach for this is cleaner and easier
1324 to work with in proxies and the like. This facility can be used in
1325 yaz-client using new command setscan which takes a result set as first
1326 argument, start position (APT) as second.
1328 Changed decoding of SRU XML packed records to deal with servers that
1329 have recordData with XML data with multiple root nodes. Also make
1330 comparison for recordPacking case insensitive. Again, one server
1331 returns "XML" where others return "xml".
1333 For SRU responses allow Content-Type application/xml as well as text/xml.
1335 --- 3.0.4 2007/05/21
1337 Fixed bug in character set conversion of BER strings. Bug introduced
1340 --- 3.0.2 2007/05/08
1342 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1344 For OID class, use oid_class consistently.
1346 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1349 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1350 character set for bibliographic information interchange". By Giannis Kosmas.
1352 Added documentation on new OID API.
1354 --- 3.0.0 2007/05/02
1356 Changes to generic frontend server interface: added new member
1357 'query_charset' for bend_initrequest structure. A backend init handler
1358 should set this member to its native character set for query terms.
1359 When defined, the frontend server logic will announce this character set
1360 to a client if the negotiationModel bit is set by the client. All server
1361 implementors are encouraged to specify this. If a backend server does not
1362 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1364 Added CCL utility to remove terms (stop words) from resulting RPN
1365 tree. This is handled by functions with prefix ccl_stop_words_ .
1367 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1368 terms in RPN queries.
1370 Clean-up the CCL API. Moved some internal structures from ccl.h to
1371 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1372 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1373 This is replaced by ccl_parser_find_str which takes a string instead.
1375 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1376 libyaz.la is the core of YAZ except the generic frontend server and
1377 does not depend on POSIX threads anymore. libyaz_server.la is the
1378 generic frontend server facilities and uses POSIX thread functionality
1379 if available. The libyaz.la no longer depends on POSIX threads because
1380 the number of global structures is limited. NMEM no longer re-uses blocks
1381 between threads ; it simply free's memory immediately but allocates in
1382 "large" chunks as usual. We don't expect any performance penalties
1383 because of this. The yaz_log system is still using a global log_level so
1384 caution must be taken when modifying it with yaz_log_init_.. +
1385 yaz_log_mask_str. This, however, should not cause any trouble because
1386 these functions are called during initialization of application code
1387 anyway. `yaz-config --libs server` returns libs for server applications;
1388 `yaz-config --libs` returns libs for non-server applications.
1390 New OID database - with public definitions in oid_db.h. Removed old OID
1391 database including the head oid.h and definitions such as enum oid_value
1392 and struct oident. The new OID database uses the same string names as
1393 before but the 'protocol' is gone. There are now only two representations
1394 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1395 converts from string to OID; functions with prefix yaz_oid_to_string
1396 converts the other way.
1398 Change to emit_term() in CQL-to-PQF query translation: when a term has
1399 the /regexp relation modifier, do not process it for leading and
1400 trailing "^" and "*", which have quite different meanings in regular
1403 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1404 write handlers no longer carries a 'last' parameter. This will make
1405 yaz_iconv flush "less" characters. A flush is performed by call to
1406 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1408 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1409 removed, because function yaz_query_to_wrbuf does the same.
1411 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1412 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1414 Deprecated MARC utility functions removed.
1416 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1419 Branch split: YAZ_2_1_55_branch
1421 --- 2.1.54 2007/03/16
1423 Fix to ZOOM-C so that transparent reconnection is properly handled on
1424 connections that are in asynchronous mode.
1426 Fixed compilation on OpenBSD 4.0.
1428 Large strings in GRS-1 records are now properly displayed in yaz-client.
1430 Added character conversion support for "advancegreek"; based on patch from
1433 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1434 sequence is met. Before the error was not set so it would be unknown.
1436 Adjust yaz-marcdump MARC reader so that it skips until record separator
1439 --- 2.1.52 2007/03/07
1441 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1442 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1443 fd_set structure used as a bitmask for the FDs to be selected on.
1445 Using ACX_PTHREAD macro to check for POSIX threads.
1447 Fixed have-vsnprintf check.
1449 --- 2.1.50 2007/02/23
1451 Fixes for configure on BSD. Bug #900.
1453 Added snprintf/vsnprintf wrappers for systems that don't have
1454 limits (heavens forbid).
1456 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1457 created before all previous tasks were completed and removed from the
1458 task queue, the new task could be removed by a mistake.
1460 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1462 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1464 Fixed bug #832: Problem with MARC/charset in yaz-client.
1466 Fixed bug #668: save command line history for yaz-client.
1468 Fixed bug #830: pkg-config support.
1470 --- 2.1.48 2007/01/23
1472 Extended ZOOM result set options with two options that may be read by
1473 a client: resultSetStatus and presentStatus with values as specified for
1475 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1477 Fixed bug #827: Using SSL fails on Debian etch.
1479 Fixed bug #826: Weird looking chars for set of MARC records.
1481 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1482 that is treated as an ItemOrder with itemRequest being an XML document
1483 external. The value of "doc" is the content.
1485 Extended the GFS search facility. New member of bend_search_rr
1486 'estimated_hit_count' signals that hits is known to be an estmate
1487 (higher or lower than real hit count). New member 'partial_resultset'
1488 signals that the search was partial (hit count is lower or equal than
1489 real hit count). For Z39.50, the information is stored in resultSetStatus
1490 member of SearchResponse APDU. For SRU, the information is signalled
1491 via SRU diagnostic 59: "Result set created with valid partial results
1494 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1496 --- 2.1.46 2007/01/13
1498 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1500 Added ZOOM_connection_peek_event.
1502 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1503 the following new functions:
1504 ZOOM_event_nonblock, ZOOM_connection_process,
1505 ZOOM_connection_get_{socket,mask,timeout},
1506 ZOOM_connection_fire_event_{timeout,socket}.
1507 The existing blocking event handler, ZOOM_event, is a wrapper for the
1508 + blocking ZOOM_event_sys_{poll,select}.
1510 Implemented function ccl_xml_config which parses XML version of CCL
1511 configuration (bug #798).
1513 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1515 Added timings utility (yaz/timing.h)
1517 --- 2.1.44 2007/01/03
1519 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1522 Fixed bug #779: Rotation of apdu.log fails.
1524 Fixed for character set conversions:
1525 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1526 Honor G1 set in MARC-8 decoding.
1528 --- 2.1.42 2006/12/17
1530 Fixed bug #775: char conversion does not handle Alternative UTF-8
1533 Implemented function yaz_marc_read_line which parses MARC line format
1534 records. There is a wealth of formats out there. So far, this function
1535 reads line records produced by yaz_marc_write_line.
1537 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1538 more generic and easier to remember(!) options: -i format and -o format
1539 which specifies input format and output format respectively - where
1540 format is one of "marc", "marcxml", "line", "marcxchange".
1542 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1543 does not print anything except warnings for records.
1545 For yaz-marcdump, added support for MARC split into files (-s) with a given
1548 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1549 spec, at http://www.loc.gov/standards/sru/record-update/
1550 This has changed the binary layout of the following structs:
1551 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1552 bend_update_rr . Patch by Ko van der Sloot.
1554 Added GFS utility function bend_assoc_is_alive which returns 1 if
1555 association is still alive (client is connected); 0 otherwise (client
1556 closed connection). This allows busy servers to stop working for
1559 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1560 been a separate piece of software. This version of ziffy has been modified
1561 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1563 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1565 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1566 Client code may now interrogate options such as "init_opt_sort" to
1567 find out whether the server claims to support various options.
1569 --- 2.1.40 2006/11/27
1571 Added utilities yaz_{set,get}_esn to set/get element set name from
1574 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1575 of YAZ and has been so since YAZ 2.1.10.
1577 Implemented ZOOM_record_error which returns error information for
1578 record (surrogate diagnostic).
1580 --- 2.1.38 2006/10/31
1582 Updates for SRU Update by Ko van der Sloot:
1583 1. Changed name from "operation" to "action"
1584 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1585 versions in the code, marked as 'backward compatible'.
1586 3. Added diagnostics for SRU Update.
1588 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1590 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1592 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1594 For GFS, fixed problem with SRU diagnostic 'First record position out of
1595 range' being issued for 0 hits.
1597 zoomtst10 part of Windows Build.
1599 --- 2.1.36 2006/10/13
1601 Implemented yaz_filepath_comp which splits a path into file path
1602 components (required by Zebra 2.0.3+).
1604 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1605 BSD inspired license until now so this should not have any real impact on
1606 anybody. See http://www.opensource.org/licenses/bsd-license.php
1608 Fixed bug #687: Missing log lines.
1610 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1613 Fixed bug #689: SRU diagnostics to be added.
1615 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1616 whether a connection is idle (no more work do do).
1618 --- 2.1.34 2006/10/04
1620 Change type of optval from long to int for invocation of setsockopt with
1621 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1623 Added support for specifying the max log file size for the Generic
1624 Frontend Server. The size is given with option -r.
1626 --- 2.1.32 2006/09/21
1628 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1630 --- 2.1.30 2006/09/17
1632 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1635 Fixed bug in Generic Frontend Server that could cause a server to stop
1636 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1638 For the generic frontend server, the maximum record size is used as maximum
1639 size of incoming packages (SRU + Z39.50). The value until was previously
1640 only used in Z39.50 Init negotiation and, later, in a session controlled
1641 sizes of records returned. This is controlled using -k option. It can be
1642 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1644 --- 2.1.28 2006/09/04
1646 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1649 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1651 New option for yaz-marcdump -lpos=value which allows setting a portion
1652 of MARC header to a certain value.
1654 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1656 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1657 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1659 --- 2.1.26 2006/08/15
1661 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1664 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1666 --- 2.1.24 2006/08/08
1668 Fixed MARC ISO2709 encoding routines to deal with character set
1671 Minor changes to GFS logging. Database included in search request log
1674 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1675 cached/multiple records.
1677 Shared libraries are built by default on Unix+configure.
1679 Changed cql2pqf transformation to use a different evaluation order. The
1680 new order is: always, relation, structure, position, truncation, index
1681 and relationModifier. Old order was: always, relation, relationModifier,
1682 structure, index, position, truncation. Note that the the latter ones
1683 override former ones for identical attributes.. The new scheme means that
1684 it is possible to override any existing attribute with a relationModifier.
1685 And also that it is possible to override everything for the index rule
1686 (except the ones listed in relationModifier). No order is perfect but this
1687 one, we believe, covers more real cases.. The "always" should have been
1688 called "default", since the attributes there can be overridden with all
1691 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1692 compilation phase, but also for yaz-config --cflags output. This allows
1693 us to have public headers with Libxml2 stuff in them . It should also,
1694 eventually, make Libxml2 checks redundant in packages using YAZ, such
1697 --- 2.1.22 2006/06/15
1699 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1700 stored in uri, message and details.. Previously diagnostics were stored
1701 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1702 compatibility.. but he's probably the only one affected, so.
1704 Added support for CCL, compiled on the client side, in ZOOM-C. This
1705 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1706 input; the resulting query objects can be used for for searching with
1707 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1709 YAZ' configure searches for OpenSSL by default.
1711 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1712 SL_CTX_use_certificate_file. See
1713 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1714 for more info. Thanks to Ko van der Sloot.
1716 --- 2.1.20 2006/06/02
1718 Bug #600: SRU GET, POST support for yaz-client. Introduced
1719 command 'sru' which selects method SOAP/GET/POST.
1721 Allow missingValueAction to be specified for the sortspec string -
1722 function yaz_sort_spec. By default, the missing value action is null.
1723 Use ! to specify "abort". Use = followed by stringvalue to specify default
1726 Ensured that Present-handler (if defined) is called in GFS before any call to
1727 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1728 searchRetrieve requests.
1730 Documentation for YAZ is now based on the Docbook XML/XSLT using
1731 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1732 is no longer depending on jade/openjade or docbook-to-man scripts.
1733 PDF is no longer part of the distribution - but can optionally be
1734 made using DSSSL/jadetex or FOP.
1736 Added retrieval handling support in Generic Frontend Server to support
1737 conversion between MARC/XML as well as XSLTtransforms. See
1738 etc/yazgfs.xml for an example.
1740 Added Authentication support to Generic Frontend Server in SRU
1741 mode. Authentication using HTTP Basic is supported, as is the use
1742 of 'x-username' and 'x-password' parameters in the request itself.
1744 Added support for a new character set MARC8s identical to MARC8 except
1745 that it converts combined characters to single Unicode characters in the
1746 Latin-1 range (when possible).
1748 --- 2.1.18 2006/04/24
1750 ASN.1 compiler 0.4: generates brief Doxygen file header for
1751 generated .h/.c files.
1753 Utility yaz_iconv now supports conversion to MARC-8.
1755 New facilities for the MARC module. The reading - and writing of
1756 content are separate methods for the yaz_marc_t handle. The following
1757 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1758 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1759 format). Write functions have prefix yaz_marc_write_.. The existing
1760 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1761 available. Removed support for OAI-MARC and simplexml (not the
1762 simplexml from PHP5).
1764 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1765 to be returned for this connection.
1767 --- 2.1.16 2006/03/31
1769 Allow multiple languages and charsets to be specified with
1770 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1771 negcharset iso-8859-1,utf-8
1773 Translation of proximity nodes from CQL into PQF now works.
1775 Moved to automake 1.8, 1.9.
1777 Added function yaz_log_set_handler which allows a log handler to be
1778 installed. This handler will be called for all log messages. Output
1779 to file is also produced; but that can be disabled by passing NULL
1780 fname to yaz_log_init_file.
1782 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1784 For SRW (including GFS), accept application/soap+xml as content-type
1787 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1788 produces NO stylesheet reference even if a default stylesheet is specified
1791 --- 2.1.14 2006/03/14
1793 Updated Windows package to include yazd.dll + yazd.lib for the
1794 Development component.
1796 If the environment variable YAZ_LOG is set, then it is used as a
1797 string indicating the default level of logging to use if not
1798 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1799 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1800 used as before. So, for example, to omit warnings from YAZ logging,
1801 export YAZ_LOG=-warn
1803 cql_transform() now map structure and other attributes before indexes,
1804 so that index-specific structures and other attributes can override
1805 defaults. So now a combination of mapping specifications such as:
1807 index.dc.date = 1=date-modified 4=5
1808 does the right thing.
1810 cql_transform() now also respects the "always" mapping specification,
1811 which establishes an initial set of attributes to be used for all
1812 terms except where overridden by more specific attributes associated
1813 with the index, relation or modifier.
1815 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1816 which mode to use; one of "post", "get" or "soap" (SRW, default).
1818 Fixes for yaz_iconv routines: changed trie-based character set conversions
1819 to use only non-negative values for bit fields due to Sun's C compiler not
1820 supporting negative values.
1822 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1823 sequences where not read correctly. Fix by Rustam Usmanov.
1825 Updated win/makefile to use options, settings which makes things
1826 compile with VS C 2005.
1828 --- 2.1.12 2006/02/01
1830 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1832 In ZOOM socket code, use select instead of poll on MacOSX.
1834 ZOOM-C now support client-side compilation of CQL into RPN that is
1835 sent to the server, enabling CQL to be used against all Z39.50
1836 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1837 ZOOM_query object, and submit it using ZOOM_connection_search().
1838 The CQL-to-RPN translation uses a configuration file, the name of
1839 which must be specified in the Connection's "cqlfile" option.
1841 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1842 function, which takes as its start-term parameter a ZOOM_query object
1843 (which may have had either CQL or RPN set into it).
1846 --- 2.1.10 2005/11/29
1848 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1849 GFS to support this as well. Backend handler, bend_srw_update, does the
1850 update work. Code contributed by Ko van der Sloot.
1852 Allow retrieval of Search Result-1 information in ZOOM by the use of
1853 options that are attached to a result set. ZOOM documentation updated
1856 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1857 UTF-8 conversion. Patch by Raj Patel.
1859 Added option -m to GFS to control formatting of timestamps in log file.
1861 Added 'exit' as synonym for 'quit' in yaz-client
1863 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1864 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1865 for the new members. Patch by Ko van der Sloot.
1867 Added support for SRU POST. It is supported for content-type
1868 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1870 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1871 Instead make the library libyaz.la multi-threaded. Threading as a whole
1872 can still be disabled by configure option --disable-threads. Previosly,
1873 with older GLIBCs there were problems with MT libs under Apache. This
1874 has now been fixed a long time ago.
1876 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1879 CQL module modified to be case insensitive for relations/indexes/operations.
1881 Fixed bug in CQL transform code: incorrect value relationModifieder
1884 Added 'show all' command for yaz-client which retrieves all results
1887 Added new yaz-client, xmles, which takes a (private) OID and
1888 a document to be sent as an extended service request.
1890 Describe new yaz-client commands wait_response and set_auto_wait.
1892 Increase TCP/IP listener backlog from 3 (which I am guessing was
1893 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1894 that the socket will queue as many incoming connections as it's able
1895 to handle ongoing connections. In other words, it will never now
1896 refuse a connection that it would be able to handle merely because
1897 it's not got around to accepting() enough of the pending connections
1898 yet. This is the behaviour anyway under Linux, where the listen()
1899 argument is ignored; but not under BSD and on systems such as
1900 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1901 YAZ-based servers should now be uniform across operating systems in
1904 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1905 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1906 This allows yaz-marcdump to read large MARC batches (>2 GB).
1908 Modified all YAZ source files - except the source which is auto-generated
1909 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1912 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1913 corresponding to the existing *_setl() function. These allow option
1914 values containing arbitrary valuues.
1916 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1917 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1918 except that it returns an indicator of whether or not the sort
1919 criterion was accepted (0 for OK, -1 for invalid).
1921 --- 2.1.8 2005/06/07
1923 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1924 MARC output rather than returning "new" buffer.
1926 yaz-client warns about unknown init options.
1928 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1930 --- 2.1.6 2005/05/24
1932 Added support for SRW sort in Generic Frontend Server. Patch
1933 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1934 sortKeys - or NULL if none is provided.
1936 Fixed bug #307: It was impossible to specify indefinite/no timeout
1937 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1940 Added support for multiple languages and charsets to be specified in
1941 ZOOM. Each charset/language is separated by a blank. If negotiation is
1942 in effect in init-response, Option
1943 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1944 Code based on patch by Vasiliy Osadchuk.
1946 Fixed bug #306: infinite recursion that occurred when calling
1947 yaz_log_level_init as the first call (before other log level or
1950 Fixed bug in scan handling in front end server: if preferred-Position-In-
1951 Response was non-present, a NULL pointer referece was performed.
1953 --- 2.1.4 2005/04/26
1955 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1956 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1957 now defined for all those error codes. So instead of putting 109 in
1958 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1959 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1961 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1964 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1966 Program yaz-client now exits and produces an error message if multiple
1967 Z39.50 servers are specified on the command line (none or one allowed
1970 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1973 --- 2.1.2 2005/03/16
1975 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1977 Fixed bug #272: Preserve spacing for CCL terms.
1979 --- 2.1.0 2005/03/14
1981 Added support for virtual hosts and multiple backend servers for
1982 the YAZ frontend server. The configution is XML based and
1983 support specificition of CQL to RPN mappings and explain information.
1984 See section "Virtual Hosts" in the YAZ manual.
1986 Extended OPAC display utility. OPAC display utility renders
1987 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1988 to supplement yaz_marc_decode_wrbuf.
1990 Fixed a bug in MARC decoder that could caused it to crash for some
1991 invalid MARC records. More diagnostics and warnings where added in
1992 XML output (warnings, etc are stored in comments).
1994 --- 2.0.34 2005/02/08
1996 Fixes for UNIX domain sockets. Bug #261.
1998 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2000 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2001 Added yaz_marc_subfield_str which defines subfield lead string which is
2002 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2003 yaz_marc_endline_str which defines end of fields string used in
2004 YAZ_MARC_LINE format. Default string is newline.
2006 Experimental support for MarcXChange. This format can be produced
2007 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2008 http://www.bs.dk/standards/MarcXchange.xsd
2010 Added yaz-client commands scansize that sets maximum number of
2011 entries to be returned by scan.
2013 --- 2.0.32 2005/01/11
2015 Added support for SRW scan in yaz-client and Generic Frontend Server.
2017 * Added whereInList member to SRW Scan Term.
2019 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2021 Fixed NMEM system to return aligned blocks on the smallest boundaries
2022 that are suitably aligned for all possible types on the particular
2023 architecture YAZ is being built for.
2025 --- 2.0.30 2005/01/04
2027 Fixed numerious warnings that was issued with newer versions of GCC.
2029 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2030 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2033 Make YAZ Generic Frontend Server slightly faster.
2035 Enhance (and reduce) logging for Generic Frontend Server.
2037 Revert YAZ log system so that it flushes every write operation
2038 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2040 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2041 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2042 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2043 will effectively disable old definitions.
2045 --- 2.0.28 2004/11/09
2047 Added yaz_log_time_format which specifies log format using
2050 Added yaz_log_module_level which returns mask for a module. Value
2051 is non-zero mask a if module is enabled; zero if disabled.
2053 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2054 in include/yaz/cql.h.
2056 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2058 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2060 Fixed bug #172: RPM builds does not enable SSL.
2062 Doxyfile.in part of dist. Doxyfile generated by configure.
2064 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2065 are given and the corresponding component does not exist.
2067 Extend CCL documentation in YAZ reference. Describe r=r.
2069 --- 2.0.26 2004/10/01
2071 Fixed MARC->MARCXML conversion to properly deal with
2072 fields, subfields, indicators having non-ASCII characters.
2074 Fixed MARC->MARCXML conversion so that ASCII control characters
2075 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2078 Added YAZ GFS support for conversion from Z39.50 surrogate
2079 diagnostics to SRW surrogate diagnostics.
2081 Bug fix: YAZ GFS did not return schema in explainResponse.
2083 --- 2.0.25 2004/09/30
2085 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2086 now converts recordSchema to elementSetName as well as schema URI.
2088 Fixed bug in COMSTACK that prevented HTTP request packages from being
2091 --- 2.0.24 2004/09/29
2093 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2094 does not require white-space before and after the dash in a range, e.g.
2095 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2098 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2099 due to new GCC removing "redundant" code.
2101 Added yaz-client commands scanpos and scanstep that sets preferred
2102 position and step-size for scan.
2104 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2106 Added CCL utility ccl_qual_buf which parses one or more CCL
2107 spec lines in a buffer.
2109 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2110 of name and value - ignoring empty lines and comments.
2112 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2114 Added odr_get_element_path which returns current element path for an
2115 ODR handle. This utility is useful in error handling or user-defined
2118 Added ODR_PRINT utility odr_set_stream which is is a more generic
2119 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2120 to a write function and pointer to close function. The close function - if
2121 non-NULL - will be called during odr_destroy.
2123 Fixed bug in CCL parser where truncation char was not removed from
2124 right side when truncation=both was in effect.
2126 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2129 --- 2.0.23 2004/08/11
2131 Fix buffer overrun in CQL parser when dealing with proximity (%).
2133 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2134 to UTF-8/UCS conversion is now only based on codetables.xml.
2136 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2138 --- 2.0.22 2004/08/06
2140 Add support for more "commit changes" in ZOOM (uses Extended Services).
2142 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2145 Yet another small fix for configure of SSL.
2147 --- 2.0.21 2004/05/14
2149 Fix SSL libs for configure when --with-openssl=DIR is given.
2151 --- 2.0.20 2004/05/10
2153 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2155 SSL comstack now uses yaz.pem certificate file on server side
2156 by default. Certificate filename can be configured by calling
2157 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2159 Fix bug regarding multiple calls to ZOOM_connection_connect.
2161 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2163 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2164 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2166 ZOOM now allows inspection of X509 peer certificate for verification.
2167 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2169 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2170 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2171 as "modular" but it simplifies things.
2173 Added cs_get_peer_certificate to that returns peer X509 PEM.
2175 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2176 NULL if SSL is unavailable.
2178 Documentation about MARC decoding tools.
2180 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2182 --- 2.0.19 2004/03/30
2184 Rename CHANGELOG to NEWS to follow GNU style packing.
2186 Fix bug with missing initialization of member in init_diagnostics.
2187 This bug affects threaded version of GFS server.
2189 --- 2.0.18 2004/03/20
2191 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2194 Ensure zlib.dll is packed with Windows install.
2196 --- 2.0.17 2004/03/17
2198 Fix encoding of xsd:string to use text instead of CDATA.
2200 Fix endless loop in CQL parser with unbalanced ".
2202 Use a more compact way to store MARC-8 conversion tables.
2204 --- 2.0.16 2004/03/16 Debian only
2206 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2209 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2214 --- 2.0.15 2004/03/01
2216 Another fix for decoding of XML packed records.
2218 --- 2.0.14 2004/02/25
2220 Fixes for Chunked encoding. White space not ignored after length spec.
2222 Update NS and use default NS for SRW diagnostic elements.
2224 --- 2.0.13 2004/02/23
2226 Implement ZOOM_resultset_cache_reset which resets record cache.
2228 Implement ZOOM_resultset_sort which sorts a result set.
2230 Implement chunked HTTP transfer.
2232 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2234 --- 2.0.12 2004/02/16
2236 Added member 'schema' to bend_explain_rr structure so that backend
2237 can specify explain record identifier. Defaults to Zeerex 2.0.
2239 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2241 --- 2.0.11 2004/02/16
2243 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2246 Added init command for yaz-client which sends "extra" init request.
2248 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2249 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2251 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2253 Make ZOOM error code for "invalid query".
2255 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2257 --- 2.0.10 2004/02/05
2259 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2262 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2264 Added option -p <file> to make Generic Frontend Server to write PID file.
2266 Added option -D to put Generic Frontend Server in background on its own.
2268 Make ZOOM C recognize option "password". If unset, "pass" is used
2269 (for backwards compatibility).
2271 Fixed a bug in Generic Frontend Server that could make it crash if a
2272 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2275 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2276 Must be issued before open, in order to be in effect.
2278 --- 2.0.9-6 2004/01/12 Debian/Windows
2280 Make the SRU server more picky WRT unknown params, etc.
2282 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2284 New YAZ client command, options, that sets Z39.50 options.
2286 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2287 options from a string of tokens (one token for each option bit).
2289 Update SRW diagnostic code messages.
2291 --- 2.0.9-5 2004/01/07 Debian/Windows
2293 Handle user defined stylesheet for SRW/SRU.
2295 --- 2.0.9-4 2004/01/06 Debian/Windows
2297 Fix bug in decoding of Content-Length.
2299 --- 2.0.9-3 2004/01/06 Debian/Windows
2301 Fix a bug with decoding of XML packed records.
2303 --- 2.0.9-2 2004/01/05 Debian only
2305 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2307 Fix bug in SRW/SRU diagnostics decoding.
2309 --- 2.0.9 2004/01/05
2311 Fixed bug in Generic Frontend Server which could drop records exceeding
2312 preferred message size. Reported and fixed by Irina Dijour.
2314 Fixed calculation of package size for structured records in Generic
2315 Frontend Server. Reported and fixed by Irina Dijour.
2317 Fixed namespace for SRW/SRU diagnostics.
2319 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2321 --- 2.0.8 2003/12/22
2323 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2324 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2327 CQL changes to reflect recent changes to the specification:
2328 * Documentation talks about context sets instead of index sets.
2329 * Documentation talks about indexes instead of qualifiers.
2330 * The CQL-to-PQF transformer's configuration file now uses
2331 "index.set.name = <attributes>" instead of the old form
2332 "qualifier.set.name = <attributes>". (Both forms are still
2333 understood but the latter is deprecated.)
2334 * CQL terms with no explicit index specified are now interpreted as
2335 cql.serverChoice instead of srw.serverChoice (which of course
2336 behaves exactly the same.)
2338 --- 2.0.7 2003/12/16
2340 MARC conversion can now generate ISO2709 output in another
2341 character set. yaz-marcdump uses this facility if you invoke it
2344 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2345 functions from there can be used from C++.
2347 --- 2.0.6 2003/12/04
2349 Frontend server now transfers memory from decoded packages to stream
2352 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2353 references to show up.
2355 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2356 the ZOOM Abstract API. The older names for the same options are still
2357 also supported for the benefit of old applications.
2359 ZOOM-C supports "implementationId" and "implementationVersion" options
2360 to go along with "implementationName". These allow the user code to
2361 specify identification strings to be sent to servers.
2362 Add OID for the new ExtLite attribute set.
2364 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2365 as requested/supplid by Ere Maijala <ere@atp.fi>
2367 For generic frontend server, reverse the order of
2368 "toolkit-supplied / application-supplied" strings sent as implementationId,
2369 Name and Version. Also, remove the spaces around the slash. This brings
2370 the GFS in line with the behaviour of ZOOM-C on the client side.
2372 Add function ZOOM_scanset_display_term.
2374 yaz-client shows scan displayTerm if present.
2376 Utility yaz-iconv is now installed by default along with the man page
2379 Extend configure check for OpenSSL to use pkg-config where available (such
2382 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2383 server to specify uid/gid/mask for socket using the format
2384 unix:[user=uid,][group=gid,][umask=mask,]file=path
2385 If file= is omitted the existing format is assumed, e.g.
2387 in which case the mask is 0666 (rw for everybody).
2389 Major restructure of YAZ source. All source in libyaz is in src directory.
2390 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2391 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2393 Added man page for utility yaz-marcdump (used to be called marcdump).
2394 yaz-marcdump is installed by 'make install'.
2396 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2397 of incoming package failed.
2399 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2401 Change prototype of odr_perror: add const to message string.
2403 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2405 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2406 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2407 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2408 DNS lookup. There should not be any compatibility problems with this
2409 assuming that blocking=1 or 0 is used.
2411 Fix bad reference in UNIX comstack in function cs_addrstr.
2413 Fix for compilation on AIX.
2415 The generic front-end server (server/seshigh.c) now supports returning
2416 Init diagnostics to the client in User-information-field, in
2417 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2420 --- 2.0.4 2003/09/04
2422 Allow any CQL relation (not just all,any,exact,scr).
2424 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2425 that features the same UI.
2427 Implemented command update0 in YAZ client which is equivalent to
2428 update but uses old of Ext Update ASN.1.
2430 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2431 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2432 Previously no OID was used for this info.
2434 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2435 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2436 returns 'malformed search term' otherwise.
2438 SortResponse member resultCount now set to NULL in sort handler of
2441 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2444 Add three new utility functions for translating OIDs between various
2445 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2446 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2447 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2448 char *oid_to_dotstring(const int *oid, char *oidbuf);
2449 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2451 Reverted modifications for ES Update definition for z_IU0Update
2452 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2453 is back to YAZ 2.0.2.
2455 String value attributes for CCL parser.
2457 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2458 which their FirstSearch server returns in Init responses, sometimes
2459 carrying useful diagnostic information when Init fails. This has the
2460 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2461 "z39.50/oclcui.asn", where its definition is somewhat different from
2462 what OCLC document on their web-site, as required to interoperate with
2465 Support for anonymous authentication in yaz-client. Use the command
2468 * Fix the OID of the Index Data-local "admin" Extended Service from
2469 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2470 the 1000, which indicates a locally-defined OID, was a mistake.
2472 --- 2.0.3 2003/06/20
2474 Fix CCL directive @case handling so that it affects string match for
2475 both CCL keywords and qualifiers.
2477 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2478 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2479 Decoder has been updated with ASN.1 changes as listed in
2480 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2481 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2482 z_IUUpdate, remains unchanged.
2484 ZOOM_record_get may now return a record in a specific character set.
2485 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2486 "from" is the character set of record as returned by target. "to" is
2487 the character set to be returned. If omitted, "to" is UTF-8.
2489 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2491 New ODR utility, odr_getelement, which returns name of element for
2492 which encoding/decoding failed.
2494 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2495 in cases where a required element was omitted.
2497 Bug fix: some MARC8 sequences were not converted.
2499 New ZOOM option "step" which specifies number of records to be
2500 retrieved in one chunk. Used in conjunction with "start" and "count".
2502 SRW support for yaz-client. Use scheme http: to use it, e.g.
2505 yaz-client no longer does (un)intelligent character set conversions
2506 by default. Can be enabled with charset and marc_charset commands.
2508 xmalloc trace fix for 64-bit systems such as DEC alpha.
2510 Solaris 2.6 compile fix.
2512 New function, cql_strerror() translates SRW error codes, as returned
2513 by cql_transform_error(), into human-readable English strings. Used
2514 in yaz-client diagnostics when appropriate.
2516 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2517 converts it into a type-1 query which is sent to the server. This
2518 makes CQL available for use with all Z-servers, as opposed to the tiny
2519 minority that can handle CQL queries themselves.
2521 --- 2.0.2 2003/04/28
2523 New Debian package layout similar to the Redhat Package layout.
2525 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2526 and search result respectively.
2528 --- 2.0.1 2003/04/25
2530 Redhat package is now several packages: libyaz (runtime libraries),
2531 libyaz-devel (development and documentation, and yaz (utility programs).
2532 Package spec file by Morten Bogeskov.
2534 New member 'schema' in struct bend_fetch_rr which the name of requested
2535 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2536 handler MAY set this to reflect the schema of the returned record.
2538 New member 'display_term' in struct scan_entry. GFS now sets member entries
2539 and allocates scan entries to be filled by user scan handler. In previous
2540 version, entries member was allocated by the scan handler. That still works,
2541 but the GFS will ignore member display_term - assuming it was NOT set by
2542 the handler. The fact that the GFS now allocates the entries both allows
2543 for new members and makes a scan handler easier to write.
2545 Fix CQL lex buffer overflow.
2547 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2548 SRU default recordPacking is string.
2550 SRU protocol support for frontend server.
2552 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2554 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2556 Added scan for the ZOOM shell (zoomsh).
2560 * String Identifers for Schemas (Amendment 5).
2561 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2562 Old definition for schema
2563 Odr_oid *schema; /* OPT */
2568 Z_InternationalString *uri;
2569 #define Z_Schema_oid 1
2570 #define Z_Schema_uri 2
2573 * resultCount parameter to Sort Response (Amendment 1).
2574 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2576 Support for SRW 1.0 over HTTP. This is an optional feature and
2577 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2580 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2581 on the same port. SRW SearchRetrieveRequests are mapped
2582 to bend_init,bend_search,bend_fetch,bend_close.
2584 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2586 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2587 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2589 ZOOM connections are SRW based if schem http is used for hostname
2590 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2591 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2593 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2594 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2595 distance=n, order=true/false, relation=le, prox unit=word. If
2596 n is omitted, distance 1 is used.
2598 Fixed problem with C compiler include path in wrong order.
2600 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2601 on Solaris. Patch from Ko van der Sloot.
2603 New MARC decode API. All new functions operate on a yaz_marc_t
2604 handle. The most important new functions are: yaz_marc_create,
2605 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2606 decode and destroy respectively. Decoder can produce formats
2607 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2608 include/yaz/marcdisp.h.
2610 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2611 to UTF-8, UCS-32, wchar_t or Latin-1.
2613 * Prototypes for yaz_iconv_-functions moved to separate header
2614 include/yaz/yaz-iconv.h.
2616 Make a few private functions 'static' in unix.c. This prevents
2617 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2619 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2620 are set when Init Response is received.
2622 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2623 but returns diagnostic set as well.
2625 New function yaz_strerror which is a portable wrapper for
2626 strerror/strerror_r/GetLastMessage.
2628 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2629 is returned for MARC. If type is "oai", then OAI MARC is returned.
2631 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2634 --- 1.9.2 2002/11/26
2636 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2638 Fix bad race conditions on SIGTERM and terminate gracefully in
2641 Move retrieval (data1) module to Zebra since nobody seems to be
2644 Add GRS-1 render for ZOOM using same format as yaz-client.
2646 --- 1.9.1 2002/10/05
2648 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2650 Fix broken ESpec handling in data1 module.
2652 SGML reader parses comments and makes them part of the data1 tree.
2654 Added several type casts so that YAZ compiles as C++ code.
2656 ZOOM didn't handle PDU encoding failures properly.
2658 Added more Bib-1 diagnostics (approved extensions).
2660 GNU configure: better check for iconv.
2662 More portable use of accept, getpeername. Check for socklen_t. Use
2663 int/size_t if socklen_t is not defined.
2667 PQF parser rejects bad queries - including those with extra
2668 characters in them. PQF parser used to silently ignore that.
2669 Cleaner API for PQF added, which allows you to get detailed
2670 error information for bad queries (see yaz/pquery.h).
2672 Fixed bug in ZOOM_record_get for type "database".
2674 Implemented mini iconv library supporting conversions between
2675 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2677 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2679 --- 1.8.9 2002/08/20
2681 Fixed ZOOM C record cache so that preferredRecordSyntax and
2682 elementSetName is used to check for already fetched records.
2684 --- 1.8.8 2002/08/02
2686 Added three members in bend_initrequest structure to facilitate
2687 character set negotiation.
2689 Fixed a bug in frontend server that could cause indefinite
2690 loops under rare conditions.
2692 Revised character set utilities (charneg.h) so that encoding
2693 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2695 For PQF, directive @term <type> sets term type for Scan/Search.
2696 Here <type> is general, string, numeric, null. The term type
2697 is inherited - just like @attr.
2699 New call odr_set_charset that sets character set conversion for
2700 international-strings on a ODR stream. Prototype is:
2701 int odr_set_charset(ODR o, const char *to, const char *from);
2702 The InternationalString is still represented as C string in YAZ
2703 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2704 won't). On the protocol level, you can use any encoding.
2706 Support for UNIX sockets in ZOOM.
2708 Solaris recv sometimes returns errno == ENOENT. It is treated as
2709 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2711 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2712 both client and server. Code by Morten Bogeskov.
2714 --- 1.8.7 2002/05/22
2716 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2717 that they can be used directly from Visual Basic. You must recompile
2718 your windows APP if you're using ZOOM.
2720 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2721 Commands "lang" and "charset" sets language and character set respectively.
2722 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2723 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2725 Attributes from multiple CCL fields may be OR'ed rather than merged
2726 using directive "@field or". Fields are still merged by default -
2727 equivalent to "@field merge".
2729 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2732 Fixed bug in zget for parameter ExtendedServicesResponse.
2736 --- 1.8.6 2002/03/25
2738 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2740 Client displays USR.1:SearchResult-1 (hits per term).
2742 Additional Search Info for search in Generic Frontend Server.
2744 Fixed CCL parsing of "field=s".
2746 WIN32 installer - using the excellent NSIS software from nullsoft.
2748 Fixed CCL parsing of "field = - <number>".
2750 Added function yaz_marc_decode that decodes MARC for line mode
2751 display or XML (similar to that used by JZKit).
2753 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2754 Z39.50. But ISO/ILL was, however.
2756 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2757 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2759 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2760 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2762 --- 1.8.5 2002/02/03
2764 New YAZ client features: Command completion and new commands:
2765 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2766 Code provided by Jacob Poulsen.
2768 New call oid_trav, that visits all registered OIDs via callback.
2770 Function ZOOM_record_get now returns const char pointer rather than
2771 void pointer. It saves a lot of type casts.
2773 For YAZ client, command "auth" now allows you to set authentication
2774 in IdPass style. It is enabled when three tokens are given - order
2775 is user, group and password.
2777 Fix memory leaks in MARC record handling for ZOOM.
2779 New option for YAZ client, -k <kilobytes> that sets
2780 maximum record size. Similar to -k option for generic frontend
2781 server and yaz-ztest.
2783 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2785 Prefix query parser reports "fail" when bad attribute set is given.
2787 Fix in MARC decoder. Proximity logging. Fix for attribute set
2788 in scan handler for server. Patches by Shigeru Ishida.
2790 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2793 Configure option --with-openssl=<dir> now works when a directory is
2794 specified. Patch provided by Morten Bogeskov.
2796 New option for YAZ client, -u <auth>, that sets authentication.
2798 ZOOM fix: error information was sometimes "missing", since error
2799 was cleared/reset too when it shouldn't.
2801 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2803 --- 1.8.4 2002/01/04
2805 Scan for ZOOM API. New object ZOOM_scanset. New functions
2806 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2807 ZOOM_scanset_destroy.
2809 New ZOOM function, ZOOM_connection_last_event, that returns type
2810 of last event (such as "receive data", "send data", "apdu received",
2813 New ZOOM option, schema, that specifies schema for retrieval.
2815 New CCL feature. Qualifiers can be aliases for one or more
2816 other qualifiers (if more than one is given, OR is used).
2818 ZOOM uses named result sets if target supports it.
2820 Two new YAZ client commands: . (dot, which sources a script of YAZ
2821 client commands), and ! (to execute shell command.). Implemented
2824 Working on Debian packages.
2826 --- 1.8.3 2001/11/19
2828 YAZ client enables named result sets only if target supports it.
2830 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2832 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2833 with key="host" to get same result.
2835 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2836 Function Z3950_resultset_record(s) returns references to records
2837 "owned" by resultset. To become owner use Z3950_record_clone.
2839 Function z_ext_record handles Extended Services. Thanks to
2842 --- 1.8.2 2001/11/12
2844 CCL Parser fix: ignore token comma when dealing with and-lists.
2846 Documentation updates for COMSTACK.
2848 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2849 Changed prototype Z3950_records. For some functions, int parameters
2850 were changed to size_t.
2852 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2855 New MARC decode/display function, marc_display_exl, which properly rejects
2856 non-ISO2709 records. YAZ client uses it.
2858 --- 1.8.1 2001/10/29
2860 Fix bug: local attribute set wasn't set correctly in PQF strings.
2864 * Old Z39.50 codecs no longer supported.
2866 Added ZOOM C binding. See http://zoom.z3950.org/
2868 Renamed states for COMSTACKs to avoid confusion with events.
2870 Implemented cs_look and proper cs_rcvconnect.
2872 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2874 Configure detects POSIX threads on OpenBSD.
2876 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2877 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2879 When error is returned from present handler, non-surrogate diagnostic
2880 is returned in present response (and fetch handler is no longer called).
2882 * Minor adjustments to pquery parser (PQF). Token characters may be
2883 escaped by using backslash (C-style).
2885 PQF parser allows string attribute values to be specified. For @attr,
2886 non-numeric characters after the equal-sign are treated as strings
2887 (e.g. @attr 9=title).
2889 CCL trunction character may be defined (@truncation in file)
2891 * function zget_ExtendedServicesRequest sets waitAction to
2892 waitIfPossible (was wait).
2894 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2897 CCL operator names may be set in field definition files (CCL_bibset).
2898 See ccl/bib1 for an example.
2900 Fixes in ASN.1 compiler for C++ compatibility.
2902 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2903 and "op_or" to avoid conflict with C++.
2905 Fixed problem with GNU readline detection on Redhat 7.0.
2907 Added step-size for Scan backend handler.
2909 Fixed bug that made the frontend server crash when no attribute
2910 set was specified for scan.
2912 Front-end server automatically switches to original working directory
2913 when installed as an NT service. Previously -w had to be specified to
2916 Added extended attributes for retrieval module (data1), so that data1
2917 records carry d1_readXML/SGML attributes. d1_read also supports
2918 null-data rules ( <tag/>)
2920 On UNIX when POSIX threads are available, a separate library libyazthread
2921 is created. Programmers should link with that library and the yaz library
2922 when using threads. The reason for the split was that some applications
2923 on Linux, such as Apache, doesn't work well when using shared objects that
2926 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2927 (or any frontend server) in SSL mode by specifying ssl: followed by
2928 address. Only tested on UNIX.
2930 Added feature for CCL module. Virtual structure s=al or s=ol generates
2931 and-list and or-list respectively instead of phrase search.
2935 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2936 log_mask_str. This was done to avoid name conflicts with other libraries
2937 (such as other PHP extensions).
2939 Added raw OID member for preferred record syntax (request_format_raw)
2940 and returned record syntax (output_format_raw) for backend fetch method.
2942 Config file yaz-config now accepts options so that it returns specific
2943 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2945 Shared library support for UNIX using GNU libtool.
2947 * Modified backend interface. Request/Response struct's replaced by
2948 one read/write C struct. For example bend_fetchrequest and
2949 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2950 Every handler - even search has to be registered in bend_init
2951 handler. This means that the YAZ library no longer refers to
2952 external functions and it makes it possible to make the whole
2953 thing a single DLL/SO.
2955 Added Segment handler for backend server.
2957 Added Zmbol/Zebra administrative functions to YAZ client.
2959 Threaded frontend server on UNIX (when POSIX Threads are available).
2960 Starting the server with option -T enables multi-threading.
2964 Added configure option --enable-comp/disable-comp to control use
2965 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2966 located in sub directory asn.
2968 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2969 in ${exec_prefix}/bin along with the other programs yaz-client and
2972 GNU automake used to maintain makefiles.
2974 Added several OID's.
2976 Changed retrieval module so that we can load records with no abstract
2977 syntax defined. Tagpaths in these records are fully composed of string
2980 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2984 On UNIX, the generated makefile now supports a proper 'make install'.
2985 The prefix can be set via GNU configure to set the install location
2986 (default is /usr/local).
2988 * YAZ programs client and ztest were renamed to yaz-client and
2989 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2990 locations, such as /usr/bin,/usr/local/bin,etc.
2992 * YAZ Header files were moved from include to include/yaz. YAZ Header
2993 files are referred to as include <yaz/log.h> rather than <log.h>.
2994 The YAZ include path (-I ..) is therefore the same as before. Programmers
2995 should update their #include statements or use -Ipath/include/yaz
2996 instead. The main motivation for doing this change is that YAZ header files
2997 can be installed in "standard" locations /usr/include,/usr/local/include
2998 without introducing conflicts, since ALL YAZ header files are stored
2999 in subdirectory yaz (under /usr/include for example).
3001 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3002 rather than project/workspace files. We switched because project files
3003 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3006 Changed name of logging function, logf, to yaz_log, to prevent name
3007 clash with some math-log functions. The YAZ header log.h defines logf
3008 to yaz_log (#define) so there should be no incompatibilities by this
3011 Added bend_start/bend_stop handlers for server. These handler are
3012 called on start/stop of server. For windows they are called whenever
3013 a service is started/stopped.
3015 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3016 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3017 in util/yc.tcl. The auto-generated C code structures are, in a few
3018 cases, incompatible with the old decoders. There are differences in the
3019 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3020 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3021 The preprocessor variable ASN_COMPILED is defined when the compiled
3022 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3023 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3024 wish to use the old encoders/decoders you can specify --disable-yc
3027 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3028 version so that it supports both new - and old version of DB Update
3030 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3031 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3032 change. The name parameter can be set to 0 in which no name is specified
3033 for the construction. The macros odr_implicit and odr_explicit sets name
3034 parameter to zero for the construction involved. New macros
3035 odr_implicit_tag and odr_explicit_tag are similar to the others,
3036 except that a name parameter is added. For programmers' that don't use
3037 ODR they probably only need to change the call to z_APDU and z_External.
3039 Added access control facility by interfacing the TCP wrapper library.
3040 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3041 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3042 name of the daemon and enables the access control as specified in
3043 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3045 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3046 den Dool <H.M.vdnDool@kub.nl>.
3048 Added reference ID parameter to most functions in server API - refer
3049 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3051 Changed name of ccl library to libccl.a (was ccl.a).
3053 Fixed bug in decoder for Explain (Category TargetInfo).
3055 Added support for GNU readline in client. Thanks to Jacob Poulsen
3056 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3058 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3059 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3060 IMPLEMENTATION! This change was made to the development version before
3061 the ZIG decided to retract the amendment. If any users MUST be
3062 compatible with the original Update definition, PLEASE CONTACT US, and
3063 we will include a separate definition corresponding to the old Update
3064 ES. Note that because of the change to the ASN.1 of the
3065 TaskPackageRecordStructure we cannot define a single structure that
3066 will support both versions.
3068 * Added const modifier to buffer parameter for some ODR/BER encoding
3069 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3070 completeWAIS, odr_dumpBER.
3072 Fixed bug in client.c which caused a crash when a scanResponse didn't
3073 contain positionOfTerm.
3075 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3076 * will cause an error in a client if a non-YAZ target sends both a
3077 * list of Scan entries and non-surrogate diagnostics.
3079 Retrieval module enhancements. Tag sets may be typed in the reference
3080 to it. From the .abs-file the "tagset" directive takes a third optional
3081 integer type for the tag set referenced. From a .tag-file the "include"
3082 directive takes a third optional type as well. The old "type" directive
3083 in the tag set itself is still recognized but acts as the default type
3086 Backend interface change. Individual Scan terms returned from bend_scan
3087 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3088 in include/backend.h.
3090 Retrieval module enhancements. Multiple tag sets and attribute sets may
3091 be specified in abstract syntax specs. Revised the error/warning for
3092 logging messages reported by the retrieval module when reading the
3095 Object Identifier system (oid_..) changed. The API is backwards
3096 compatible but the oid-routines now allocates new OID's when needed.
3097 Raw OID's may be specified in oid_getvalbyname.
3099 YAZ now uses GNU configure to generate Makefile(s).
3101 * Minor changes in some of the member names of DeleteResultSetRequest and
3102 DeleteResultSetResponse. See include/proto.h.
3104 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3105 and added member 'languages' in TargetInfo (which was missing).
3107 Changed the way attribute sets are handled in the retrieval
3108 module. These are now cached, just like the abstract syntaxes
3111 Changed YAZ so that it links with compiled ASN.1.
3113 Added Explain-schema definitions and mapping routines. The following
3114 Explain categories have been implemented: AttributeDetails,
3115 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3117 Fixed minor bug in Windows version of Server Library.
3119 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3121 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3123 Added EXTERNAL: UNIverse Resource Report (non-standard).
3125 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3126 ENUMERATED and SET OF.
3128 * Added 'const' to some of the char pointer arguments for the
3129 functions, data1_read_node, data1_getelementbytagname,
3130 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3133 Fixed bug in data1_insert_taggeddata - the last_child member of
3134 parent wasn't initialised.
3136 * Changed data1_read_record and data1_read_node so that the supplied
3137 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3138 doesn't refer to any parts of the "SGML"-buffer.
3140 Fixed bug in server library (Windows version of statserv_remove).
3142 * Changed code so that it compiles as C++. The type definition
3143 of Odr_fun which is a member of Odr_arm was changed. The result is,
3144 that an explicit typecast is needed for the fun pointer when
3145 using Odr_arm - as in:
3146 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3148 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3150 Implemented the new structured date and time definition as approved
3151 by the ZIG. Added schemaId element to the specificTag in Espec-1
3152 (also approved at the last ZIG). Thanks to RVDM.
3154 Added some Object identifiers (RVDM).
3156 Changed the Update Extended Service (RVDM).
3158 Added command "refid" to client which specifies referenceId for
3159 the following requests.
3161 Implemented extended service handling for server. See ztest.c
3162 for an example as well as backend.h. New handlers are registerd
3163 in the Init handler.
3165 * Changed interface for sort in server.
3167 Added new members to statserv_options_block. It allows a server
3168 to read options from another source than just the command line. Thanks
3169 to Charles Woodfield.
3171 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3172 renamed to zboolean. Some C++ compilers complained about the name.
3174 Minor changes to gils.abs. Added index 's' (sort) on title
3175 and date/time-last-modified.
3177 --- 1.4pl2 1998/1/30
3179 Fixed bug in server library regarding inetd mode (-i). This bug
3180 was introduced by release 1.4.
3182 --- 1.4pl1 1998/1/29
3184 Added sort facility in client and backend server interface.
3186 Fixed problem with dependencies in Makefile(s).
3188 Fixed bugs for encoders/decoders of extended services and
3191 Implemented sub-tree feature for schemas. Sub-trees are
3192 referenced in *.abs-files. See explain.abs for an example
3193 of the use of this feature.
3195 Modified bib1.att; local attributes for ANY didn't include
3196 ANY itself (only affects use of the retrieval module).
3198 Fixed bug in plain SGML reader in function data1_read_node:
3199 tags with prefix "var" was incorrectly interpreted as variants.
3201 Added feature "sub-schemas" to enable references to - and definitions
3202 of - group of elements.
3204 * Removed member parent from type data1_element (in data1.h).
3206 Implemented function odr_nullval() that returns the value of
3209 * Removed member num_children from data1_node (in data1.h).
3211 Made NT service interface part of the server library. The
3212 function statserv_main uses the NT service when required and
3213 calls the statserv_start / statserv_close routines.
3215 Routine zget_SearchRequest and zget_PresentRequest fills
3216 resultSetName/Id member with "default" instead of "Default".
3218 Fixed memory leak in server. Request queue member wasn't freed.
3220 Fixed nmem_exit so that memory is freed.
3224 Revised the CCL parser utility to be thread safe.
3226 Added function, oid_ent_to_oid, to replace the function
3227 oid_getoidbyent, which is not thread safe.
3229 * Added nmem_init and nmem_exit to initialize and release
3230 NMEM resources. Function nmem_init should be called once in the
3231 initial thread before NMEM/ODR is used. statserv.c and client.c
3232 have been changed accordingly. The change was necessary to make
3233 NMEM thread safe. The NMEM memory pool is shared amongst threads
3234 in a process. Unix-based applications will still work fine without
3237 Added NT Services interface for the the Z39.50 (statserv) Server.
3238 Refer to the ztest.c source on the usage.
3240 Windows 95/NT port using MSVC5.0. Project files are included in the
3243 * Defined new 'global' handle for the retrieval (data1) system. The
3244 new handled, data1_handle, describes the state of the data1 system.
3245 This handle is passed as first argument to virtually all
3246 data1 related routines. The functions data1_create and data1_destroy
3247 creates and destroys a data1 handle respectively.
3249 Added ODR encode stream member to all backend request structures
3250 init, search, scan etc. This stream should be used to allocate all
3251 memory used for the response when thread safe operation is needed.
3253 Changed the comstack utility, cs_addstr, to be thread safe. The
3254 returned hostname string returned by the function is now part the
3257 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3258 function. The cs_straddr takes a COMSTACK handle as argument, so this
3259 function must be used after cs_create and before bind/connect.
3260 This function is thread safe.
3262 Moved test server to 'ztest' directory - generic server code still
3263 in 'server' directory.
3265 Made prefix query (pquery.c) utility thread safe.
3267 Added new function modifier YAZ_EXPORT to 'export' public DLL
3268 functions when using windows (see include/yconfig.h).
3270 Added definitions to the OID database (util/oid.c) (RVDM).
3272 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3274 Added call to ccl_rpn_delete in client program.
3276 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3277 release of RPN structure.
3279 Added support for C++, headers uses extern "C" for public definitions.
3280 With input from RVDM.
3282 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3283 Thanks to Ronald van der Meer (RVDM).
3285 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3287 Added support for private extensions to the OID database
3288 (oid_setprivateoids()). Thanks to RVDM.
3290 Added optional, physical ANY (key replication)
3292 Fixed null-reference problem in GRS-1 output filter.
3294 Proximity operator added to Prefix Query Format (PQF).
3296 In test client command "base" accepts multiple databases.
3298 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3302 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3304 Smallish bug-fixes in the new encoders/decoders (explain).
3306 Bug fixed in DeleteRequest.
3308 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3310 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3312 Added SOIF syntax (using private OID for now) to retrieval module and client.
3314 Added Update extended service.
3316 Added SearchResult-1 additional info structure.
3318 Added optional CCL (ISO8777) interpreter as separate module. Available
3321 --- 1.2 1996/6/10 (1st anniversary release)
3323 Added Summary record syntax. Lightly tested.
3325 Added OPAC record syntax. Untested.
3327 Added ResourceReport service encoders/decoders. Untested.
3329 Fixed bug in z_Unit - wrong tagging on unitSystem.
3331 Fixed bug in the DiagRecs decoder.
3333 Added options for max PDU size and session timeout to frontend-server.
3335 Added documentation of query-language parsers and other supporting utilities.
3337 [frontend-server] Added Attribute set to the bend_scanrequest API.
3339 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3340 surrogate diagnostics were generated.
3342 [retrieval] Allow multiple local values for attribute.
3344 [retrieval] Allow multiple attributes per element in .abs files. index type.
3346 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3348 --- 1.1pl2 1996/4/10
3350 Minor changes, mostly specific to Zebra's requirements (retrieval)
3354 Repaired bug in frontend server when running multiple listening
3355 endpoints in dynamic mode.
3357 z_External() now won't break if a known, ASN.1 value comes encapsulated
3358 in an octet-string. The value will pass through unmodified in an Odr_oct.
3360 Added a bit of code to the demo client to decode & display
3361 ASN.1-structured records represented in the octet-aligned branch of
3362 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3364 Added z_ext_getentbyref() to the ASN module. Doc updated.
3366 * Completed the SCAN definition in the ASN module. This may break SCAN
3367 code based on older YAZ-versions at compile-time. The fix is easy -
3370 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3371 under the SCAN definition. Remember to initialize this, server-people.
3373 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3374 that this does not extend to ODR and ASN.
3376 Comstack allows insertion of established socket (primarily for
3377 inetd-operation of servers). Doc updated.
3379 Front-end server can now start from the inetd in TCP mode. Doc
3382 --- 1.0pl4 1996/1/24
3386 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3387 the rank and record number.
3389 Adjustments to the frontend server.
3391 Fixed diagnostic BER dumper. It ignored the file argument.
3395 Various changes to retrieval module.
3397 Changed the union discriminators of the protocol files from enums to
3398 ints paired with #defines.
3400 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3403 *Changed operator in the RPN structure to 'roperator', again to avoid a
3406 Fixed problems in Explain decoders/encoders.
3408 --- 1.0pl2 1995/12/6
3410 Memory bug in log module fixed.
3412 --- 1.0pl1 1995/12/5
3414 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3416 Bug in Explain DatabaseInfo module fixed.
3418 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3422 The shift to v1.0 signals that we now consider the *core* functionality
3423 of YAZ reasonably stable (the core being more or less equivalent to
3424 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3425 tested (Explain not at all - though that will happen soonish).
3427 Minor changes to code to support Windows port.
3429 Various minor changes after we're getting to use GRS-1 & co. more.
3431 Added Espec-1 format.
3433 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3434 of the protocol and it cannot be selected when encoding (maps into 'string'
3435 when decoding). Needed to talk to some servers.
3437 Demo client can request simple element set names.
3439 Added Diagnostic Format encoders/decoders.
3441 Added simple Close handling to frontend server (no hooks for resource
3442 reporting yet), and demonstration client.
3444 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3446 --- 1.0b3 1995/08/24
3448 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3449 handled incorrectly when records were requested in the searchResponse. This
3450 will only affect you if you use the frontend-server.
3452 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3453 Test-client will ask for and print GRS1. Ztest will return dummy records
3456 Added Explain encoders/decoders to the service-level API. Untested.
3458 Added Extended Services: Item Order encoders and decoders to the Service-
3459 level API. Untested. We could use a recent copy of the pertinent bits
3460 of the ILL protocol to add those bits.
3462 Added diagnostic format 1 encoders/decoders to the service-level API.
3465 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3466 odr_cons.c, which causes a more correct output.
3468 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3469 was always set to 0 when no records were requested in the searchRequest.
3471 * Added better external-handling. This shouldn't harm old code that
3472 *encodes* externals. It can break code that looks for a
3473 'single-ASN1-type' representation, since those types that are known
3474 are now decoded immediately. Look at the SUTRS sample code in
3475 seshigh.c and client.c. Documentation updated.
3477 Handling of structured records in bend_fetchresponse. Length -1 marks
3478 structured record, type is deduced from format field.
3480 --- 1.0b2 1995/06/27
3481 Fairly quick maintenance release to add SUTRS support.
3483 Fixed handling of SUTRS records in the demonstration client.
3485 * Added format field to the bend_fetchrequest and bend_fetchresponce
3486 structures of the backend API (frontend server). When the record is
3487 returned, the value of the format field is mapped to an OID. The
3488 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3489 of the record. The special value VAL_NONE in the bend_request means
3490 that no specific format was requested by the client. Documentation
3491 updated accordingly. Test server (ztest) will return a fixed dummy
3492 SUTRS record if your client requests SUTRS.
3494 Documentation updated accordingly.
3496 You can now set external libraries and RANLIB support in the top-level
3500 First public release.
