3 New charset, MARC-8c, which is like MARC-8 but allows control characters
4 0x01 through 0x1F, except ESC to be passed through verbatim.
6 Fix a problem with duplicate sub field character in MARC output. Problem
7 happened only when output was MARC-8 encoded.
11 yaz-ztest: Use hash for fake hit count. Before, random number was used.
12 This is problematic for unit tests using yaz-ztest. This patch also makes
13 a hash for CQL queries. For RPN, any term with a leading digit will be
14 treated as pseudu hit count (to force any particular hit count by a client).
16 yaz-ztest: return unique MARC dummy records. Beyond record offset
17 24, the author surname is patched with offset to make all records
20 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
21 on system wide default (/proc/sys/net/ipv6/bindv6only).
22 @4 binds to IPV4 only. @6 binds to IPV6 only.
24 Update CQL API documentation a bit
26 CQL: don't accept extra terms for queries. Makes the CQL parser
27 stricly conformant to the standard.
31 GFS: scan handler gets extra_args from request and may return extra
32 response data . That's for SRU only.
34 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
38 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
40 OPACXML: sync spelling of availabilityDate in XML to that of Schema
41 opaxxml.xsd. The schema had the correct spelling of this member always.
42 The ASN.1 was mis-spelled and still is (API change) - we are
43 not changing this. However, the OPAC to XML conversion had yet
46 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
49 New function, z_ext_record_oid_nmem, which is similar to
50 z_ext_record_oid but takes NMEM rather than ODR
54 ICU: New conversion element 'join' which joins tokens into one
55 with a custom character given by rule attribute.
59 New GFS search member: present_number. This is a hint to the
60 search handler how many records are going to be fetched immediately
61 following search. There's no guarantee that it's going to be the case,
62 since it depends on hit count (for Z39.50 piggyback) and whether errors
65 Make a few functions static (private). The functions getbyte_stream,
66 ungetbyte_stream and yaz_gets are now private. They were never declared
69 yaz-marcdump: exit(5) for serious decoding errors
71 ISO2709 decoding: be more picky WRT header
73 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
74 was only used as to indicate that next-result-set-position should be
76 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
77 Based on patch from Ashley Sanders.
79 Make some functions static/private in PQF parsing. Those functions were
80 never declared in a public header and so should not be in use by
81 applications based on YAZ.
85 ZOOM: special options to control APDU logging.
86 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
87 logging of APDUs until "saveAPDU" option is set again. If logging is
88 already enabled the effect is that current APDU buffer is cleared.
89 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
90 logging (default behavior on new connection).
91 The APDUs sent/received can be obtained by using
92 Using ZOOM_connection_option_get(c, "APDU") or
93 ZOOM_connection_option_getl(c, "APDU", &l).
95 GFS: relay implementation_version from backend
96 From 3.0.40 and later, implementation_version from backend was
97 not used in init response at all.
101 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
102 mode at all. Probably never did.
104 Make a new version of ztest.pem that, at least, is not expired.
106 --- 4.2.45 2012/11/13
108 Fix description of CCL directive 'case'.
110 More tight checking of form arguments (yaz_uri_to_array). Makes
111 YAZ better at rejecting big and/or bad POSTs.
113 SRU decoding does not report more than up to 10 invalid arguments.
115 rpn2cql: less quotes in generated terms. Semantics unchanged, but
116 it's prettier this way.
118 --- 4.2.44 2012/10/25
120 New utility yaz_decode_init_diag. Defined in proto.h.
122 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
123 given for unix local socket.
124 The COMSTACK string for doing so is:
127 unix:/myfile:tcp:localhost:9999/mybase
128 unix:/myfile:localhost:9999/mybase
129 unix:/myfile:http://fakehost/mybase
131 debian: Use dpkg-buildflags in build process.
133 --- 4.2.43 2012/10/19
135 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
136 global's SRU service uses a recordPosition scheme starting from zero.
137 First record's position should be one
138 according to the standard.
140 --- 4.2.42 2012/10/18
142 Allow more namespaces for SRU. This is to allow, for example, an
143 incorrect namespace returned from server
144 http://services.igi-global.com/sru .
146 Minor fixes for compilation on Windows.
148 --- 4.2.41 2012/10/11
150 daemon: log total number of bad signals from child on stop so that it
151 is more easy to spot problems with child worker processes.
153 retrieval: empty backend name attribute omits element set
154 from being used in retrieval.
156 --- 4.2.40 2012/10/04
158 Implement Solr sort strategy "solr", similar to sru11 sorting.
159 This will implement the correct parameters on Solr requst to do
162 --- 4.2.39 2012/09/28
164 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
167 MARC: Extra/missing indicator handled for MARCXML.
168 The indicator length is given in header and is the same for the
169 whole record. If attributes ind1, ind2 are missing, then content
170 character defaults to blank. Extra indicator attributes (beyond)
171 indicator length are treated as an error.
173 Reformat: delete trailing whitespace
175 --- 4.2.38 2012/09/17
177 MARC: fix non-ASCII characters for leader. This is to ensure we can
178 generate XML in UTF-8.
180 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
181 in one node with structure word.
183 --- 4.2.37 2012/09/04
185 yaz-json-parse: JSON output may be pretty printed by using option
188 Increase default value of max message for Z39.50 Init for GFS, ZOOM
189 and yaz-client. Old value was 1 MB. New value is 64 MB.
191 --- 4.2.36 2012/08/22
193 yaz-client: don't display bogus records from SRU servers. Some SRU servers
194 return more records than given by *maximumRecords*. Skipping those in
197 record_render: simplify buffer return handling and fix at least one bad
198 memory reference, that broke the test_embed_record sometimes.
200 Allow http://user:pass@host notation for yaz_url_exec.
202 zoomsh: allow shell command to be executed. Via the system(3) call.
204 yaz_poll: Allow num_fds == 0
206 yaz-client: fix bad encoding of "itemorder item". The itemorder
207 item <no> - command forgot to use length of encoded Item Request
208 package. Error present since YAZ 3.
210 yaz-ztest: fix bad usage of session handle. Bug was introduced when
211 result sets were saved (271a9c83).
213 SRU recordPacking: guess record packing in response rather than looking
214 at the recordPacking element which, OF COURSE, changed semantics in SRU
217 Decode SRU 2.0 responses. The official namespace for responses, according
218 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
219 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
220 nature.com's server, however, usee namespace
221 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
222 we are now using a glob-expr to match up the namespace. ZOOM C and
223 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
224 I can not find a single real example showing the "real" namespace in
225 the documentation from OASIS. The namespace for requests is different
226 from responses, but this is not added to YAZ yet, when we don't encode
229 --- 4.2.35 2012/06/26
231 zoom/record_render: add support for Base64 decoding fo MARC records
232 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
233 which will decode base64 + ISO2709 marc-8 encoded material from text node
236 --- 4.2.34 2012/06/07
238 Add missing definitions ZOOM_resultset_get_facet_field_by_index
239 and ZOOM_resultset_facets_names.
241 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
244 Change APDU dump printing to avoid long leading blanks. For levels 16
245 or larger the level is shown and the indentation is truncated but
246 recursed with modula 8. This makes it still reasonable easy to read
247 - even for nested BER dumps.
249 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
250 return 0 (incomplete package) in case where the BER package was
251 considered too nested (return value of -2).
253 dumpber: lines of level 15 are not indented further. Two spaces per
254 indentation; indentation 15 or more is indented to a fixed indentation
255 and augmented with a level=<no> indication.
257 zoomsh: increase max size of command+args
259 GFS: No limit in RPN buf size in CQL to RPN conversion.
261 --- 4.2.33 2012/05/09
263 New function for daemon utility, yaz_daemon_stop .
265 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
267 --- 4.2.32 2012/04/25
269 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
270 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
272 --- 4.2.31 2012/04/23
274 YAZ daemon utility relays SIGUSR1 to child process.
276 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
277 would result in en empty database list - which in turn would result in
278 encoding failure for search.
280 Fix reading beyond string in yaz_sort_spec.
282 --- 4.2.30 2012/04/11
284 Add two new SRU diagnostics:
285 236: Access to specified database denied
286 1015: Init/AC: Maximum number of simultaneous sessions for Userid
288 Document the very useful ZOOM-C option "apdulog".
290 CQL to RPN: term may be passed through verbatim. This is enabled with
291 truncation.cql . The assumption being that the term is already CQL.
293 --- 4.2.29 2012/03/20
295 record_conv: leader spec may be given for marc element.
296 The leader spec is given as attribute leaderspec for element marc.
297 For example to convert a MARC21 record from MARC-8 to UTF-8:
298 <marc inputformat="marc" outputformat="marc"
299 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
301 record_conv: allow user-XSLT params. For example:
302 <xslt stylesheet="MARC21slim2DC.xsl">
303 <param name="myparameter" value="myvalue"/>
304 <param name="otherparameter" value="othervalue"/>
307 record_conv: fix error handling for missing marc charsets.
309 CQL: fix extra terms in wrong order.
311 --- 4.2.28 2012/03/06
313 record_conv: modify new API for conversion types. The conversion types
314 may be passed in new functions yaz_record_conv_configure_t and
315 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
317 Avoid mixed statement/variable declare; fixes compilation with Visual
320 --- 4.2.27 2012/02/28
322 Add non-standard SRU diagnostic: 235: "Database does not exist".
323 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
324 Update SRU to Bib-1 diagnostic maps accordingly.
326 CCL: add two new diagnostics for unsupported masking. The new
327 diagnostics are: "Embedded truncation not supported" and
328 "Single charcacter mask not supported".
330 --- 4.2.26 2012/02/23
332 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
334 --- 4.2.25 2012/01/11
336 Build YAZ for Ubuntu Oneiric.
338 CCL: allow parantheses for proximity operands. For example CCL query
339 (a) % (b) is now allowed.
341 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
342 marked dead, rather then being destroyed. If not, the session memory is
343 being free'd before the search/scan handler is finished. Also destroy
344 'request' memory in request_release rather than in various places,
345 which resulted in leaks from time to time.
347 --- 4.2.24 2011/12/21
349 cql_sortby_to_sortkeys: honor sort prefix.
351 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
352 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
353 The rpn2cql family of functions now always returns quoted CQL terms.
355 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
357 --- 4.2.23 2011/12/15
359 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
360 sequence is treated as one. For example, &&a=b&&&c& is identical to
363 --- 4.2.22 2011/12/05
365 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
366 APDUs for a connection to a WRBUF.
368 --- 4.2.21 2011/11/23
370 Fix cql_sortby_to_sortkeys. Completely broken before.
372 Make CCL's @truncation work again.
374 --- 4.2.20 2011/11/09
376 New ZOOM connection setting: tproxy. It's like proxy, but does not
377 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
378 to set resolved address + port for a connection outside ZOOM itself.
380 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
382 --- 4.2.19 2011/11/07
384 Fix uninitialized variable in Solr spell support (could cause SEGV
385 for SRU response decoding).
387 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
388 back-end's addinfo through into the ZOOM response addinfo.
390 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
391 they are separated by a colon and a space rather than simply
394 --- 4.2.18 2011/10/28
396 Add support for Solr spell-checking/suggestions through ZOOM.
397 If a Solr target has been configured correctly for spelling-checking
398 and suggestions, these will now be returned on the ResultSet option
399 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
401 --- 4.2.17 2011/09/28
403 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
404 with a flag whether to substitute escape sequences or not.
406 --- 4.2.16 2011/09/22
408 Fix nmem_strsplit_escape to substitute escape char properly.
410 New option for zoomsh -e , which makes it abort on first error and
411 return process exit code to indicate success/failure.
413 YAZ options utility supports special option -- which makes all it treat
414 all following arguments as non-options.
416 --- 4.2.15 2011/09/16
418 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
419 searched if absolute filename is given.
421 Fix conv_xslt() error-reporting when stylesheet is not found.
422 (The value of fullpath is meaningless in this situation.)
424 --- 4.2.14 2011/09/07
426 Fix problem in CQL sort node creation: un-initialized memory.
428 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
429 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
430 CQL sortby depending on whether Type-1 or CQL is actually sent to the
433 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
434 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
436 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
437 will make it possible to use both single-character mask (#) and wildcard (?)
438 in CCL . Throw diagnostic for left truncation because that is not supported
441 --- 4.2.13 2011/09/01
443 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
444 cases using escapes (\-sequences) and masking.
446 PQF parse fix: A trailing backslash followed by end-of-string (\0)
447 would result in a read one byte beyond string.
449 rpn2ccl may use Z39.50 masking for terms (t=z).
451 ICU check fix. Don't include library -lCrun on Solaris, unless present.
453 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
454 not --cppflags (which seeems like an error in icu-config).
456 --- 4.2.12 2011/08/27 RPM package only
458 cql2ccl: fix conversion of terms: operator characters were not
461 --- 4.2.11 2011/08/25 RPM package only
463 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
464 CCL parser will map both # and ? to their regular expression
465 quivalents (. and .*).
467 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
468 of reserved CQL characters.
470 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
471 is, so that they are passed through.
473 --- 4.2.10 2011/08/24
475 ZOOM SRU mode: more aggressive re-connect.
477 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
478 made available as a utility function, declared in <yaz/logrpn.h>
480 rpn2cql_structure() supports proximity nodes (except that the Type-1
481 proximity node's "exclusion" binary is ignored, as there is no way to
482 express that in CQL). Fixes bug #4564.
486 Fix SEGV that could occur if set command of zoomsh was given without
487 value (2nd argument).
489 Fix SEGV that could occur if unsupported transport was given for
490 COMSTACK - say https (when SSL was unavailable).
492 Build yaz-url on Windows too.
496 New utility to get web content. Header is url.h. A command line tool
497 yaz-url is part of the distribution and packages.
499 Fixes for SSL COMSTACK (when gnutls is in use).
501 New functions yaz_base64{encode,decode}. Header is base64.h.
505 ZOOM C includes HTTP response buffer as additional info if it fails
506 to decode the SRU response.
508 Make wrbuf_json_puts available.
512 zoom: throw diagnostic for invalid value for option "sru". Before a
513 bad SRU request was sent.
515 Adding new utility wrbuf_vp_puts.
517 Add cclxmlconfig.obj to win/makefile. It was missing completely.
521 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
522 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
523 redirect was used at the same time.
525 MARC line mode decoding: be less picky about length given - first
526 5 digits of header that is.
528 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
530 Changes to decoding of SRU records: a record with recordPacking=xml is
531 modified with a new root element <yaz_record> if the recordData contains
532 multiple children elements. This is to make the record XML parseable
535 RPN to Solr conversion: encode special characters.
537 Generic Frontend Server: fix uinitialized member, stepSize.
541 Fix a bug in SRU decoding of records.. The database records stored
542 had un-initialized memory, but it would only be seen with yaz_record_render
543 and type_spec="ext" .
545 Fix a bug in ccl_qual_dup introduced in 4.2.3.
549 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
553 Add new utilities to convert from CQL to CCL . These utilities have
554 prefix cql_to_ccl defined in cql.h.
556 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
557 lead to memory heap corruptions when ICU utilities were in use.
561 Make compilation work without Libxml2.
563 yaz-client: remove redundant blanks in display of searchResult-1 term
568 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
569 resulting CQL node (tree) in a new node CQL_NODE_SORT.
571 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
572 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
573 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
574 Note that the CQL sortby spec is only converted when the GFS is already
575 converting from CQL to RPN (cql2rpn element).
577 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
578 specify whether to collapse delimitors or not. The existing nmem_strsplit
579 do collapse (collapse parameter = 1).
581 Windows installer: For NSIS, set InstallDir depending on x86/x64.
583 Rename internal func yaz_use_attribute_create. While non-static, this
584 function is not declared in a public header.
588 Add -lCrun when linking with ICU on Solaris.
590 More quicks character set conversions for OPAC records.
594 fix problem with record_render: records were converted (character set
595 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
599 SRU: add methods for handling DADS SRU-proxy facets.
601 Separate OPAC record character set for ZOOM_record. yaz_record_render
602 allows a character set given as charset=from/opacfrom,to where 'from' is
603 the character set of a bibliographic record, 'opacfrom' is character set
604 of OPAC record and 'to' is the target character set.
608 yaz-client: show may XML format records. Command show followed by 'format'
609 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
612 src/stemmer.c: Avoid using unnamed union. It is not supported by some
615 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
618 Update yaz.spec to operate on both SLES11 / Centos 5.5.
620 RPM: Release includes 'indexdata' name. Use indexdata in release name so
621 this package can be distinguished from other vendors.
623 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
624 as determined by configure
626 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
628 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
629 returns no error and no record, the present request is considered
630 partial (only a subset of the records could be returned by backend), and
631 so it is appropriate to set Present Status to partial-4.
635 Move yaz-config man pages to section 1.
637 More documentation about Solr.
639 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
640 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
641 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
642 peers on some Linux systems. However, in general that does not work
643 so YAZ can not rely on that to work. Debian changed behavior in this
644 respect from Debian lenny to Debian squeeze (still testing as of Oct
646 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
648 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
652 Fix yaz-config output: echo_source not set correctly by configure.
656 Solr Web Service support for yaz-client and ZOOM.
658 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
660 --- 4.0.12 2010/08/17
662 Z39.50 facet support. Facet specifications are passed for search in
663 other-information with ASN.1 as defined in facet.asn and OID
664 .10.1000.81.5 . Facets are expressed as an Attribute list as known
665 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
666 3 is limit (number of entries to get in response). yaz-ztest returns
667 dummy facets if a client asks for them.
669 --- 4.0.11 2010/07/09
671 CCL fixes: bug 2895 and bug 3539.
673 GR1-display: add comma in display - was removed by mistake in
676 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
678 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
680 --- 4.0.10 2010/06/18
682 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
683 result set from a connection. The result set will be on its own
684 thereafter; no operations on it will perform retrievals from a target.
685 Only cached copies are returned.
687 ZOOM C:fix case for HTTP servers responding with Connection:close.
688 Ensure that if there is a current task it is resumed (like fetching
689 more records in a result set) . Bug #3484.
691 PQF parser: use odr_atoi for Odr_int (not atoi)
693 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
694 values that contain any non-digits are treated as string attributes
695 (previously decoding only checked for leading character ([0-9]). PQF
696 encoding: attribute string values are not surrounded by double-quotes.
700 New utility for managing threads - thread_create.h.
702 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
703 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
704 but YAZ' implementation do.
706 Fixes for yaz_cond-functions on Windows 7.
708 DLL export more symbols.
710 zoomsh: show record do NOT render opac.
712 Remove *.la files from Debian and RPM packages.
716 Debian package libyaz-dev depends on libgnutls-dev again (was
717 removed in YAZ 4.0.6, but due to Libtool it is still needed
718 even though yaz-config do not list libgnutls libs).
720 ZOOM: Use only one WRBUF for returning string results for
721 ZOOM_resultset. Reduces memory usage for ZOOM in general.
723 ZOOM: ZOOM_connection do not use a shared pointer to
724 ZOOM_resultset after ZOOM_resultset is destructed by
725 user. Reverts to YAZ 4.0.4 behavior.
729 record-conv: fix problem with at least one XSL conversion -
730 due to probably incorrect usage of XML XSL documents.
734 Fix yaz-config for static mode and the use of SSL (gnutls).
738 Forward decl timeval struct in mutex.h and gettimeofday.h.
740 yaz-config: fix 'static' mode linking.
744 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
745 are wrappers for pthreads or Windows. For Windows these are put in
746 a separate DLL: yaz_cond4.
748 libyaz.la (whole source) is compiled with thread. If thread support
749 is enabled enabled, all source of YAZ is compiled with treading support.
750 This allows core utilities such as yaz_log to use thread facilities.
751 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
752 thread utilities. This commit moves mutex utilities (mutex.c) from
753 libyaz_server.la to libyaz.la.
755 yaz-json-parse displays leading text until error.
759 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
760 patch from Giannis Kosmas.
762 SRU: no longer URL encode SRU database. The URL for an SRU server is
763 a URL and such is alreeady encoded - at least when given with leading
764 http:// or https://. This reverts behavior to YAZ 3.0.50.
766 Support for new MARC XML notation TurboMARC which like MARCXML is a
767 complete representation of MARC/ISO2709.. This one, however, is more
768 compact and allows for faster processing with XSLT. TurboMARC can be
769 used in the marcdisp.h API, from the yaz-marcdump utility and from
772 yaz-ztest can be configured - via the database - to perform certain
773 delays when it performs operations search, present and single record
774 fetch. This allows testers to make yaz-ztest act as a real or even slow
775 Z39.50 server. Refer to the yaz-ztest man pages for details.
779 wrbuf_destroy allows NULL WRBUF passed to it.
781 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
783 Add ZOOM_connection_close.
785 No fixed size buffers for ZOOM shell - bug #3257.
787 tstodr: make it work on s390 platform.
789 New icu iterator-functions. The new icu_iter-functions makes it possible
790 to use ICU chains from many threads.
792 yaz-client: better syntax check for show command.
796 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
799 New simple local-file XML include facility which allows file glob-patterns.
800 Refer to yaz/xml_include.h.
802 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
805 ZOOM_record_get supports new parameter "format" which makes it format XML
808 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
809 JSONText in ECMA-262) is JSONValue, not JSONObject.
813 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
814 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
816 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
817 POSIX/Unix builds .so with major version 4.
819 Remove old LOG_-defines from log.h. They have been obsolete and
820 undefined by default for the last 5 years.
822 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
824 GFS: Remove socket (int *fd) from search_rr handler. The socket
825 descriptor ptr is a facility that allowed a search handler to supply
826 a socket which would serve as a callback - when search was complete.
827 This facility has now been in use for years.
829 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
830 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
831 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
832 returns 'const char *' rather than 'char *. The returned string is
833 read-only and should not be modified by applications. COMSTACK cs_close is
834 now a void function - it no longer returns int. No applications check for
835 the value and the implementations has always returned 0.
837 ZOOM: use size_t for scan hit counts and str size. Functions
838 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
839 occ (hit count) and len (string length) are now of type size_t pointer
840 rather than int pointer. This is to be able to represent large hit counts
841 and to also just to use the proper type for string length (strlen result).
843 New JSON parser. Refer to include/yaz/json.h .
845 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
846 Used to be int in some cases. Many wrbuf_-functions used to return an int
847 indicating some length.. These return values were never used. And so they
850 ODR: odr_malloc, odr_total now takes size_t for size.
852 clone_z_type: fix leak; occurred for encoding failures.
854 --- 3.0.52 2009/12/03
856 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
857 bug was introduced in 3.0.51.
859 --- 3.0.51 2009/12/02
861 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
863 tcpip comstack: fix leak for getaddrinfo.
865 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
866 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
867 Decoding of SRU "path" database is performed by private function
868 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
869 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
871 yaz-client: honor base command for SRU. Change when database setting
872 is applied for SRU and ensure it is kept when a connection is reset.
873 Change also the way errors are displayed or SRU (decoding of packages).
875 --- 3.0.50 2009/11/02
877 Add support for extra request / response data for SRU codecs and GFS.
878 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
879 for extra data response buffer and length. For the GFS, both request
880 and response data (XML) is carried in extra_args and extra_response_data
881 for the search handler. Patch by Ko van der Sloot.
883 ZOOM: For queries that cannot be converted to the specified rpnCharset,
884 ZOOM now returns a diagnostic on the client-side ('invalid query' /
885 10010). This fixes bug #2113.
887 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
888 cmdfile included a 'quit' command that would result in a memory violation.
890 --- 3.0.49 2009/10/01
892 Make a number of functions defined in xmlquery.c static. These have
893 never been declared in a public header file (yaz/xmlquery.h) and was
894 made public by mistake.
896 Improve speed of character conversions (iconv utilities). This makes
897 conversions from MARC-8 faster.
899 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
900 unless type desired is "raw". This will prevent type "xml" from
901 returning ISO2709 .. Which obviously can not be XML parsed.
903 Fix memory leak in ZOOM that would occur if option apdulog was used
904 on a re-used connection.
906 Frontend server logs HTTP requests.
908 Frontend server now sends Z39.50 close when it times out (sesssion has
909 been idle for too long). Versions 2.0.30 and earlier also sent close.
910 But due to a mistake this was disabled in all versions after that, i.e.
911 the server would just close the socket immediately.
913 yaz-client emits a better message when receiving an unrecognised
914 userInformationField.
916 Skip zero-length subfields when decoding ISO2709. This rare case happens
917 if a record has two FS characters in a sequence. Without this patch
918 there would be a reference beyond char array in using_code_len fragments
921 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
923 --- 3.0.48 2009/08/28
925 The show command offered by the zoomsh command now takes a 3d optional
926 parameter type which is what is passed to ZOOM_record. If the type
927 argument is omitted, "render" is used.
929 RPN to CQL conv may use USE string attributes (bug #2978).
931 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
933 --- 3.0.47 2009/07/08
935 Function yaz_xml2query allows a diagnostic element in the PQF XML
936 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
937 code and additional info respectively.
939 The BER BOOLEAN is now the integral type Odr_bool which still happens
940 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
941 typedef'd to Odr_int. This is still an integral 'int', but it may be
942 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
943 ASN-1 compiler as well as programs has been updated to use the new types.
945 --- 3.0.46 2009/06/08
947 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
948 only the bibliographic record was rendered. For type=opac, an OPAC
949 record is only returned if it is present.
951 iconv: small fix for encoding of advancegreek.
953 yaz-client: avoid double display of SRU/SRW records (bug #2798).
955 yaz-client: option auto_reconnect=on really reconnects.
957 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
959 server: avoid null ptr ref for for yaz_poll errors.
961 build: fix RPM build for RHEL 5.3.
963 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
965 --- 3.0.45 2009/03/31
967 Fixed bug #2709: TCP connect returns Invalid argument.
969 Fixed compilation for mingw.
971 Honor charset for raw records (ZOOM_record_get).
973 Fixed use of errno for threaded mode that was seen on Solaris 10.
975 Fixed argument passing with blanks in value for Windows Service.
977 Disable YAZ' own log rotate by default (no 1 GB limit).
978 The variable l_max_size which specifies the log file limit is set to 0
979 (DISABLED): This is due to the fact that YAZ is most often deployed using
980 logrotate. Also YAZ can not perform log rotate because of unsufficient
981 permissions (setuid).
983 --- 3.0.44 2009/02/17
985 List supported encodings in man page for yaz-iconv.
987 Fixed missing SSL libs for --libs output
989 Re-established OID record syntax application-xml. Nobody should use it
990 but we don't want to change soname because of this symbol being absent.
992 --- 3.0.42 2009/02/02
994 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
996 Added member named_result_sets for init handler struct for the GFS. This
997 allows a server to disable named result sets.
999 Removed OID record syntax application-xml.
1001 Added support for rule-based transliterator for ICU wrapper of YAZ.
1003 Fixed bug #1902: yaz-icu XML output.
1005 Make YAZ checks Emacs friendly.
1007 BITSTRING value shows value. Bug #2346.
1009 ISO2709 decoding: skip control characters from indicator data.
1011 Omit sort key by default in yaz-icu's output.
1013 Allow combined single char options (again) for YAZ' options function.
1015 Utility yaz-marcdump got option to display YAZ version (-V).
1017 Allow YAZ to use ICU 3.4.
1019 Added new ICU test case which illustrates removal of diacritics.
1021 --- 3.0.41 2008/12/29
1023 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1025 --- 3.0.40 2008/12/29
1027 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1030 Fixed bug #2352: yaz-marcdump crashes for certain record.
1032 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1034 Added support for Danmarc2 to UTF-8 conversion.
1036 Added support for ISO5426 to UTF-8 conversion.
1038 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1039 implementation version.
1041 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1043 --- 3.0.38 2008/11/10
1045 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1046 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1048 ZOOM C now interprets databaseName option for ZOOM connection as path
1051 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1053 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1055 Dummy Libxml2 types no longer defined in headers of YAZ'.
1057 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1060 --- 3.0.36 2008/09/26
1062 Various ODR chapter fixes.
1064 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1066 Added missing source for Windows compilation, mutex.c.
1068 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1070 For SRU connections in ZOOM all records up to "count" are now fetched.
1072 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1073 in Windows due to bad error handling for Libxml2.
1075 Added facility for sending arbitrary records (ASN.1 any) using
1076 ZOOM C's Extended service update. Patch by Sam Reynolds.
1078 New options for ZOOM C's connection, logapdu which makes ZOOM log
1081 --- 3.0.34 2008/06/18
1083 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1085 --- 3.0.32 2008/06/12
1087 Fixed memory violation that could occur when decoding UTF-8. This bug
1088 was only present in 3.0.30 of YAZ.
1090 --- 3.0.30 2008/06/06
1092 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1093 GNU TLS is used by default (if found).
1095 yaz-ztest returns OPAC records if a client asks for OPAC.
1097 Improved speed of MARC-8 encoding.
1099 Added support for lossy and loss-less MARC-8 encoding.
1101 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1103 Added new Windows Service wrapper (sc).
1105 yaz-client's itemorder command may now send a file.
1107 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1109 Added new function yaz_log_xml_errors.
1111 Allow (but warn) unknown XML attributes in MARCXML parsing.
1113 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1115 The UTF-8 to MARC-8 conversion now uses a different set of characters
1116 for Greek symbols. Bug #2120.
1118 --- 3.0.26 2008/02/21
1120 Added yaz_daemon (daemon.h).
1122 Fixed bug #2068: pkg-config trouble
1124 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1126 --- 3.0.24 2008/01/28
1128 Document --with-xml2 option.
1130 Added OPAC XML XSD (etc/opacxml.xsd).
1132 Allow glob mask for name attribute in retrieval element for the
1133 generic frontend server's retrieval facility.
1135 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1136 except POLLIN/POLLOUT.
1138 Fixed error handling in cs_listen. Bug #2037.
1140 --- 3.0.22 2008/01/20
1142 Fixed version in yaz/yaz-version.h.
1144 Fixed bug #2027: Crash when closing connection.
1146 Changed configure so that ICU support is only enabled if only ICU
1147 and Libxml2 is available (because the ICU chain is XML based).
1149 --- 3.0.20 2008/01/15
1151 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1152 is built. Only this DLL depends on the ICU runtime.
1154 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1155 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1157 Changed license of CCL module to 'Revised BSD'. After consultation with
1158 remaining members of the original EUROPAGATE consortium, we are re-issuing
1159 the CCL module without a separate license. The software was developed by
1160 Index Data as part of a research project. The special license was included
1161 to help feed usage information back to the project consortium to support
1162 project evaluation. At this time, the project consortium has long-since
1163 disbanded, and the majority of the original principals have retired. At the
1164 same time, we have significantly modified the software during the following
1165 years, to the point where very practically no original code remains. To
1166 simplify re-use of the software, we have contacted those members of the
1167 consortium who could be reached, and agreed to re-issue the module as a
1168 proper part of the YAZ package.
1170 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1172 CQL closer to being version 1.2 compliant. CQL also allows free-form
1173 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1176 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1177 bug could make Extended services handling crash in the ZOOM layer. This
1178 bug was only present in YAZ 3.0.18.
1180 --- 3.0.18 2007/12/19
1182 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1185 yaz-marcdump reads and writes collection wrapped records.
1187 Handle OPAC for record conversion module.
1189 Fixes for ICU wrapper.
1191 Allow ICU libs to be controlled with --with-icu .
1193 --- 3.0.16 2007/11/12
1195 Added yaz_poll which is a wrapper for select/poll. When poll is available
1196 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1197 sockets to be in use.
1199 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1200 functionality through an XML based configuration (ICU chain). This system
1201 is useful for search facilities such as Pazpar2 and Zebra that needs to
1202 perform tokenization of indexed material. The ICU code in a separate
1203 library libyaz3_icu.a.
1205 Added HTTP tunnel facility for COMSTACK, bug #1752.
1206 This is a facility that allows a Web proxy, such as squid, to tunnel
1207 Z39.50 traffic. This facility is "transparent" to must applications
1208 using YAZ. It's enabled by using pseudo transport connect: followed by
1209 the proxy address, followed by command, then follwed by he regular
1210 "virtual" addresss. For example,
1211 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1213 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1215 --- 3.0.14 2007/09/21
1217 Fixed bad memory reference in ZOOM_record - cuased by member not being
1218 initialized. This was a problem only in YAZ 3.0.12.
1220 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1221 fields were not removed.
1223 Changed the way C code is generated from codetables.xml. Made a MARC-8
1224 conversion trie for each characterSet section rather than codeTable.
1225 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1226 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1228 --- 3.0.12 2007/09/12
1230 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1231 from ZOOM_record_error).
1233 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1235 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1237 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1239 Better SRW-to-Bib-1 diagnostic mapping.
1241 ZOOM C and yaz-client announces SRU version 1.2 by default.
1243 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1246 Fixed in yaz_sru_decode to allow other version than 1.1.
1248 --- 3.0.10 2007/08/22
1250 Added support for SRU scan for ZOOM.
1252 Added support for the use of the older versions or Extended Service
1253 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1254 set to the version , 1=first, 2=second, 3=third. The third version is
1255 what ZOOM C has used so far. And that, obviously, is the default.
1257 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1258 therefore in Zebra and in SimpleServer-based applications). The new
1259 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1260 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1261 which is passed into the back-end search callback function.
1263 Added support for HTTP Basic authentication in clients: the SRU/W
1264 codec encodes the username/password elements of the PDU structure
1265 appropriately, and these may be set using the "user" and "password"
1266 options in ZOOM-C applications (the same options that are used for
1267 Z39.50 authentication).
1269 --- 3.0.8 2007/06/25
1271 Fixed bug #1208: SSL appears to be broken in ZOOM.
1273 Fixed bug #1206: Libxml2 include path weirdness.
1275 Added oid_name_to_dotstring.
1277 Allow elementSetName to be specified for ZOOM C record update.
1279 Allow waitAction to be specified for ZOOM C based for Extended Services.
1281 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1282 syntax OID. Bug introduced in YAZ 3 series.
1284 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1286 --- 3.0.6 2007/06/06
1288 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1289 directory. yaz-client now reads commands from file given by option -f
1290 if specified; then tries to read .yazclientrc in current directory.
1291 Failing that, it reads .yazclientrc from user's home directory.
1293 Added support for correlationInfo Note and ID for Record Update via
1296 Added yaz-client command querycharset which specifies character set for
1297 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1298 (termListAndStartPoint).
1300 Charset ISO5428:1984 is an alias for ISO5428-1984.
1302 Implemented a way to perform scan in a result set using Z39.50. This
1303 is achieved by attaching the result set name in the characterInfo
1304 (type InternationalString) of OtherInformation in the Scan Request PDU.
1305 The result set is identified in the otherinformation by the new OID:
1306 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1307 This allows for scan in result set and faceted search . Zebra did some
1308 of this in the APT term using attribute type 8 and value being result
1309 set. Using the OtherInformation approach for this is cleaner and easier
1310 to work with in proxies and the like. This facility can be used in
1311 yaz-client using new command setscan which takes a result set as first
1312 argument, start position (APT) as second.
1314 Changed decoding of SRU XML packed records to deal with servers that
1315 have recordData with XML data with multiple root nodes. Also make
1316 comparison for recordPacking case insensitive. Again, one server
1317 returns "XML" where others return "xml".
1319 For SRU responses allow Content-Type application/xml as well as text/xml.
1321 --- 3.0.4 2007/05/21
1323 Fixed bug in character set conversion of BER strings. Bug introduced
1326 --- 3.0.2 2007/05/08
1328 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1330 For OID class, use oid_class consistently.
1332 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1335 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1336 character set for bibliographic information interchange". By Giannis Kosmas.
1338 Added documentation on new OID API.
1340 --- 3.0.0 2007/05/02
1342 Changes to generic frontend server interface: added new member
1343 'query_charset' for bend_initrequest structure. A backend init handler
1344 should set this member to its native character set for query terms.
1345 When defined, the frontend server logic will announce this character set
1346 to a client if the negotiationModel bit is set by the client. All server
1347 implementors are encouraged to specify this. If a backend server does not
1348 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1350 Added CCL utility to remove terms (stop words) from resulting RPN
1351 tree. This is handled by functions with prefix ccl_stop_words_ .
1353 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1354 terms in RPN queries.
1356 Clean-up the CCL API. Moved some internal structures from ccl.h to
1357 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1358 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1359 This is replaced by ccl_parser_find_str which takes a string instead.
1361 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1362 libyaz.la is the core of YAZ except the generic frontend server and
1363 does not depend on POSIX threads anymore. libyaz_server.la is the
1364 generic frontend server facilities and uses POSIX thread functionality
1365 if available. The libyaz.la no longer depends on POSIX threads because
1366 the number of global structures is limited. NMEM no longer re-uses blocks
1367 between threads ; it simply free's memory immediately but allocates in
1368 "large" chunks as usual. We don't expect any performance penalties
1369 because of this. The yaz_log system is still using a global log_level so
1370 caution must be taken when modifying it with yaz_log_init_.. +
1371 yaz_log_mask_str. This, however, should not cause any trouble because
1372 these functions are called during initialization of application code
1373 anyway. `yaz-config --libs server` returns libs for server applications;
1374 `yaz-config --libs` returns libs for non-server applications.
1376 New OID database - with public definitions in oid_db.h. Removed old OID
1377 database including the head oid.h and definitions such as enum oid_value
1378 and struct oident. The new OID database uses the same string names as
1379 before but the 'protocol' is gone. There are now only two representations
1380 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1381 converts from string to OID; functions with prefix yaz_oid_to_string
1382 converts the other way.
1384 Change to emit_term() in CQL-to-PQF query translation: when a term has
1385 the /regexp relation modifier, do not process it for leading and
1386 trailing "^" and "*", which have quite different meanings in regular
1389 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1390 write handlers no longer carries a 'last' parameter. This will make
1391 yaz_iconv flush "less" characters. A flush is performed by call to
1392 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1394 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1395 removed, because function yaz_query_to_wrbuf does the same.
1397 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1398 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1400 Deprecated MARC utility functions removed.
1402 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1405 Branch split: YAZ_2_1_55_branch
1407 --- 2.1.54 2007/03/16
1409 Fix to ZOOM-C so that transparent reconnection is properly handled on
1410 connections that are in asynchronous mode.
1412 Fixed compilation on OpenBSD 4.0.
1414 Large strings in GRS-1 records are now properly displayed in yaz-client.
1416 Added character conversion support for "advancegreek"; based on patch from
1419 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1420 sequence is met. Before the error was not set so it would be unknown.
1422 Adjust yaz-marcdump MARC reader so that it skips until record separator
1425 --- 2.1.52 2007/03/07
1427 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1428 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1429 fd_set structure used as a bitmask for the FDs to be selected on.
1431 Using ACX_PTHREAD macro to check for POSIX threads.
1433 Fixed have-vsnprintf check.
1435 --- 2.1.50 2007/02/23
1437 Fixes for configure on BSD. Bug #900.
1439 Added snprintf/vsnprintf wrappers for systems that don't have
1440 limits (heavens forbid).
1442 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1443 created before all previous tasks were completed and removed from the
1444 task queue, the new task could be removed by a mistake.
1446 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1448 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1450 Fixed bug #832: Problem with MARC/charset in yaz-client.
1452 Fixed bug #668: save command line history for yaz-client.
1454 Fixed bug #830: pkg-config support.
1456 --- 2.1.48 2007/01/23
1458 Extended ZOOM result set options with two options that may be read by
1459 a client: resultSetStatus and presentStatus with values as specified for
1461 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1463 Fixed bug #827: Using SSL fails on Debian etch.
1465 Fixed bug #826: Weird looking chars for set of MARC records.
1467 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1468 that is treated as an ItemOrder with itemRequest being an XML document
1469 external. The value of "doc" is the content.
1471 Extended the GFS search facility. New member of bend_search_rr
1472 'estimated_hit_count' signals that hits is known to be an estmate
1473 (higher or lower than real hit count). New member 'partial_resultset'
1474 signals that the search was partial (hit count is lower or equal than
1475 real hit count). For Z39.50, the information is stored in resultSetStatus
1476 member of SearchResponse APDU. For SRU, the information is signalled
1477 via SRU diagnostic 59: "Result set created with valid partial results
1480 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1482 --- 2.1.46 2007/01/13
1484 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1486 Added ZOOM_connection_peek_event.
1488 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1489 the following new functions:
1490 ZOOM_event_nonblock, ZOOM_connection_process,
1491 ZOOM_connection_get_{socket,mask,timeout},
1492 ZOOM_connection_fire_event_{timeout,socket}.
1493 The existing blocking event handler, ZOOM_event, is a wrapper for the
1494 + blocking ZOOM_event_sys_{poll,select}.
1496 Implemented function ccl_xml_config which parses XML version of CCL
1497 configuration (bug #798).
1499 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1501 Added timings utility (yaz/timing.h)
1503 --- 2.1.44 2007/01/03
1505 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1508 Fixed bug #779: Rotation of apdu.log fails.
1510 Fixed for character set conversions:
1511 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1512 Honor G1 set in MARC-8 decoding.
1514 --- 2.1.42 2006/12/17
1516 Fixed bug #775: char conversion does not handle Alternative UTF-8
1519 Implemented function yaz_marc_read_line which parses MARC line format
1520 records. There is a wealth of formats out there. So far, this function
1521 reads line records produced by yaz_marc_write_line.
1523 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1524 more generic and easier to remember(!) options: -i format and -o format
1525 which specifies input format and output format respectively - where
1526 format is one of "marc", "marcxml", "line", "marcxchange".
1528 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1529 does not print anything except warnings for records.
1531 For yaz-marcdump, added support for MARC split into files (-s) with a given
1534 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1535 spec, at http://www.loc.gov/standards/sru/record-update/
1536 This has changed the binary layout of the following structs:
1537 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1538 bend_update_rr . Patch by Ko van der Sloot.
1540 Added GFS utility function bend_assoc_is_alive which returns 1 if
1541 association is still alive (client is connected); 0 otherwise (client
1542 closed connection). This allows busy servers to stop working for
1545 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1546 been a separate piece of software. This version of ziffy has been modified
1547 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1549 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1551 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1552 Client code may now interrogate options such as "init_opt_sort" to
1553 find out whether the server claims to support various options.
1555 --- 2.1.40 2006/11/27
1557 Added utilities yaz_{set,get}_esn to set/get element set name from
1560 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1561 of YAZ and has been so since YAZ 2.1.10.
1563 Implemented ZOOM_record_error which returns error information for
1564 record (surrogate diagnostic).
1566 --- 2.1.38 2006/10/31
1568 Updates for SRU Update by Ko van der Sloot:
1569 1. Changed name from "operation" to "action"
1570 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1571 versions in the code, marked as 'backward compatible'.
1572 3. Added diagnostics for SRU Update.
1574 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1576 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1578 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1580 For GFS, fixed problem with SRU diagnostic 'First record position out of
1581 range' being issued for 0 hits.
1583 zoomtst10 part of Windows Build.
1585 --- 2.1.36 2006/10/13
1587 Implemented yaz_filepath_comp which splits a path into file path
1588 components (required by Zebra 2.0.3+).
1590 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1591 BSD inspired license until now so this should not have any real impact on
1592 anybody. See http://www.opensource.org/licenses/bsd-license.php
1594 Fixed bug #687: Missing log lines.
1596 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1599 Fixed bug #689: SRU diagnostics to be added.
1601 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1602 whether a connection is idle (no more work do do).
1604 --- 2.1.34 2006/10/04
1606 Change type of optval from long to int for invocation of setsockopt with
1607 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1609 Added support for specifying the max log file size for the Generic
1610 Frontend Server. The size is given with option -r.
1612 --- 2.1.32 2006/09/21
1614 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1616 --- 2.1.30 2006/09/17
1618 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1621 Fixed bug in Generic Frontend Server that could cause a server to stop
1622 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1624 For the generic frontend server, the maximum record size is used as maximum
1625 size of incoming packages (SRU + Z39.50). The value until was previously
1626 only used in Z39.50 Init negotiation and, later, in a session controlled
1627 sizes of records returned. This is controlled using -k option. It can be
1628 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1630 --- 2.1.28 2006/09/04
1632 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1635 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1637 New option for yaz-marcdump -lpos=value which allows setting a portion
1638 of MARC header to a certain value.
1640 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1642 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1643 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1645 --- 2.1.26 2006/08/15
1647 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1650 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1652 --- 2.1.24 2006/08/08
1654 Fixed MARC ISO2709 encoding routines to deal with character set
1657 Minor changes to GFS logging. Database included in search request log
1660 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1661 cached/multiple records.
1663 Shared libraries are built by default on Unix+configure.
1665 Changed cql2pqf transformation to use a different evaluation order. The
1666 new order is: always, relation, structure, position, truncation, index
1667 and relationModifier. Old order was: always, relation, relationModifier,
1668 structure, index, position, truncation. Note that the the latter ones
1669 override former ones for identical attributes.. The new scheme means that
1670 it is possible to override any existing attribute with a relationModifier.
1671 And also that it is possible to override everything for the index rule
1672 (except the ones listed in relationModifier). No order is perfect but this
1673 one, we believe, covers more real cases.. The "always" should have been
1674 called "default", since the attributes there can be overridden with all
1677 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1678 compilation phase, but also for yaz-config --cflags output. This allows
1679 us to have public headers with Libxml2 stuff in them . It should also,
1680 eventually, make Libxml2 checks redundant in packages using YAZ, such
1683 --- 2.1.22 2006/06/15
1685 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1686 stored in uri, message and details.. Previously diagnostics were stored
1687 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1688 compatibility.. but he's probably the only one affected, so.
1690 Added support for CCL, compiled on the client side, in ZOOM-C. This
1691 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1692 input; the resulting query objects can be used for for searching with
1693 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1695 YAZ' configure searches for OpenSSL by default.
1697 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1698 SL_CTX_use_certificate_file. See
1699 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1700 for more info. Thanks to Ko van der Sloot.
1702 --- 2.1.20 2006/06/02
1704 Bug #600: SRU GET, POST support for yaz-client. Introduced
1705 command 'sru' which selects method SOAP/GET/POST.
1707 Allow missingValueAction to be specified for the sortspec string -
1708 function yaz_sort_spec. By default, the missing value action is null.
1709 Use ! to specify "abort". Use = followed by stringvalue to specify default
1712 Ensured that Present-handler (if defined) is called in GFS before any call to
1713 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1714 searchRetrieve requests.
1716 Documentation for YAZ is now based on the Docbook XML/XSLT using
1717 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1718 is no longer depending on jade/openjade or docbook-to-man scripts.
1719 PDF is no longer part of the distribution - but can optionally be
1720 made using DSSSL/jadetex or FOP.
1722 Added retrieval handling support in Generic Frontend Server to support
1723 conversion between MARC/XML as well as XSLTtransforms. See
1724 etc/yazgfs.xml for an example.
1726 Added Authentication support to Generic Frontend Server in SRU
1727 mode. Authentication using HTTP Basic is supported, as is the use
1728 of 'x-username' and 'x-password' parameters in the request itself.
1730 Added support for a new character set MARC8s identical to MARC8 except
1731 that it converts combined characters to single Unicode characters in the
1732 Latin-1 range (when possible).
1734 --- 2.1.18 2006/04/24
1736 ASN.1 compiler 0.4: generates brief Doxygen file header for
1737 generated .h/.c files.
1739 Utility yaz_iconv now supports conversion to MARC-8.
1741 New facilities for the MARC module. The reading - and writing of
1742 content are separate methods for the yaz_marc_t handle. The following
1743 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1744 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1745 format). Write functions have prefix yaz_marc_write_.. The existing
1746 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1747 available. Removed support for OAI-MARC and simplexml (not the
1748 simplexml from PHP5).
1750 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1751 to be returned for this connection.
1753 --- 2.1.16 2006/03/31
1755 Allow multiple languages and charsets to be specified with
1756 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1757 negcharset iso-8859-1,utf-8
1759 Translation of proximity nodes from CQL into PQF now works.
1761 Moved to automake 1.8, 1.9.
1763 Added function yaz_log_set_handler which allows a log handler to be
1764 installed. This handler will be called for all log messages. Output
1765 to file is also produced; but that can be disabled by passing NULL
1766 fname to yaz_log_init_file.
1768 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1770 For SRW (including GFS), accept application/soap+xml as content-type
1773 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1774 produces NO stylesheet reference even if a default stylesheet is specified
1777 --- 2.1.14 2006/03/14
1779 Updated Windows package to include yazd.dll + yazd.lib for the
1780 Development component.
1782 If the environment variable YAZ_LOG is set, then it is used as a
1783 string indicating the default level of logging to use if not
1784 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1785 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1786 used as before. So, for example, to omit warnings from YAZ logging,
1787 export YAZ_LOG=-warn
1789 cql_transform() now map structure and other attributes before indexes,
1790 so that index-specific structures and other attributes can override
1791 defaults. So now a combination of mapping specifications such as:
1793 index.dc.date = 1=date-modified 4=5
1794 does the right thing.
1796 cql_transform() now also respects the "always" mapping specification,
1797 which establishes an initial set of attributes to be used for all
1798 terms except where overridden by more specific attributes associated
1799 with the index, relation or modifier.
1801 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1802 which mode to use; one of "post", "get" or "soap" (SRW, default).
1804 Fixes for yaz_iconv routines: changed trie-based character set conversions
1805 to use only non-negative values for bit fields due to Sun's C compiler not
1806 supporting negative values.
1808 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1809 sequences where not read correctly. Fix by Rustam Usmanov.
1811 Updated win/makefile to use options, settings which makes things
1812 compile with VS C 2005.
1814 --- 2.1.12 2006/02/01
1816 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1818 In ZOOM socket code, use select instead of poll on MacOSX.
1820 ZOOM-C now support client-side compilation of CQL into RPN that is
1821 sent to the server, enabling CQL to be used against all Z39.50
1822 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1823 ZOOM_query object, and submit it using ZOOM_connection_search().
1824 The CQL-to-RPN translation uses a configuration file, the name of
1825 which must be specified in the Connection's "cqlfile" option.
1827 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1828 function, which takes as its start-term parameter a ZOOM_query object
1829 (which may have had either CQL or RPN set into it).
1832 --- 2.1.10 2005/11/29
1834 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1835 GFS to support this as well. Backend handler, bend_srw_update, does the
1836 update work. Code contributed by Ko van der Sloot.
1838 Allow retrieval of Search Result-1 information in ZOOM by the use of
1839 options that are attached to a result set. ZOOM documentation updated
1842 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1843 UTF-8 conversion. Patch by Raj Patel.
1845 Added option -m to GFS to control formatting of timestamps in log file.
1847 Added 'exit' as synonym for 'quit' in yaz-client
1849 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1850 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1851 for the new members. Patch by Ko van der Sloot.
1853 Added support for SRU POST. It is supported for content-type
1854 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1856 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1857 Instead make the library libyaz.la multi-threaded. Threading as a whole
1858 can still be disabled by configure option --disable-threads. Previosly,
1859 with older GLIBCs there were problems with MT libs under Apache. This
1860 has now been fixed a long time ago.
1862 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1865 CQL module modified to be case insensitive for relations/indexes/operations.
1867 Fixed bug in CQL transform code: incorrect value relationModifieder
1870 Added 'show all' command for yaz-client which retrieves all results
1873 Added new yaz-client, xmles, which takes a (private) OID and
1874 a document to be sent as an extended service request.
1876 Describe new yaz-client commands wait_response and set_auto_wait.
1878 Increase TCP/IP listener backlog from 3 (which I am guessing was
1879 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1880 that the socket will queue as many incoming connections as it's able
1881 to handle ongoing connections. In other words, it will never now
1882 refuse a connection that it would be able to handle merely because
1883 it's not got around to accepting() enough of the pending connections
1884 yet. This is the behaviour anyway under Linux, where the listen()
1885 argument is ignored; but not under BSD and on systems such as
1886 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1887 YAZ-based servers should now be uniform across operating systems in
1890 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1891 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1892 This allows yaz-marcdump to read large MARC batches (>2 GB).
1894 Modified all YAZ source files - except the source which is auto-generated
1895 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1898 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1899 corresponding to the existing *_setl() function. These allow option
1900 values containing arbitrary valuues.
1902 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1903 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1904 except that it returns an indicator of whether or not the sort
1905 criterion was accepted (0 for OK, -1 for invalid).
1907 --- 2.1.8 2005/06/07
1909 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1910 MARC output rather than returning "new" buffer.
1912 yaz-client warns about unknown init options.
1914 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1916 --- 2.1.6 2005/05/24
1918 Added support for SRW sort in Generic Frontend Server. Patch
1919 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1920 sortKeys - or NULL if none is provided.
1922 Fixed bug #307: It was impossible to specify indefinite/no timeout
1923 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1926 Added support for multiple languages and charsets to be specified in
1927 ZOOM. Each charset/language is separated by a blank. If negotiation is
1928 in effect in init-response, Option
1929 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1930 Code based on patch by Vasiliy Osadchuk.
1932 Fixed bug #306: infinite recursion that occurred when calling
1933 yaz_log_level_init as the first call (before other log level or
1936 Fixed bug in scan handling in front end server: if preferred-Position-In-
1937 Response was non-present, a NULL pointer referece was performed.
1939 --- 2.1.4 2005/04/26
1941 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1942 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1943 now defined for all those error codes. So instead of putting 109 in
1944 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1945 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1947 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1950 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1952 Program yaz-client now exits and produces an error message if multiple
1953 Z39.50 servers are specified on the command line (none or one allowed
1956 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1959 --- 2.1.2 2005/03/16
1961 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1963 Fixed bug #272: Preserve spacing for CCL terms.
1965 --- 2.1.0 2005/03/14
1967 Added support for virtual hosts and multiple backend servers for
1968 the YAZ frontend server. The configution is XML based and
1969 support specificition of CQL to RPN mappings and explain information.
1970 See section "Virtual Hosts" in the YAZ manual.
1972 Extended OPAC display utility. OPAC display utility renders
1973 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1974 to supplement yaz_marc_decode_wrbuf.
1976 Fixed a bug in MARC decoder that could caused it to crash for some
1977 invalid MARC records. More diagnostics and warnings where added in
1978 XML output (warnings, etc are stored in comments).
1980 --- 2.0.34 2005/02/08
1982 Fixes for UNIX domain sockets. Bug #261.
1984 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1986 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1987 Added yaz_marc_subfield_str which defines subfield lead string which is
1988 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1989 yaz_marc_endline_str which defines end of fields string used in
1990 YAZ_MARC_LINE format. Default string is newline.
1992 Experimental support for MarcXChange. This format can be produced
1993 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1994 http://www.bs.dk/standards/MarcXchange.xsd
1996 Added yaz-client commands scansize that sets maximum number of
1997 entries to be returned by scan.
1999 --- 2.0.32 2005/01/11
2001 Added support for SRW scan in yaz-client and Generic Frontend Server.
2003 * Added whereInList member to SRW Scan Term.
2005 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2007 Fixed NMEM system to return aligned blocks on the smallest boundaries
2008 that are suitably aligned for all possible types on the particular
2009 architecture YAZ is being built for.
2011 --- 2.0.30 2005/01/04
2013 Fixed numerious warnings that was issued with newer versions of GCC.
2015 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2016 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2019 Make YAZ Generic Frontend Server slightly faster.
2021 Enhance (and reduce) logging for Generic Frontend Server.
2023 Revert YAZ log system so that it flushes every write operation
2024 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2026 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2027 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2028 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2029 will effectively disable old definitions.
2031 --- 2.0.28 2004/11/09
2033 Added yaz_log_time_format which specifies log format using
2036 Added yaz_log_module_level which returns mask for a module. Value
2037 is non-zero mask a if module is enabled; zero if disabled.
2039 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2040 in include/yaz/cql.h.
2042 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2044 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2046 Fixed bug #172: RPM builds does not enable SSL.
2048 Doxyfile.in part of dist. Doxyfile generated by configure.
2050 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2051 are given and the corresponding component does not exist.
2053 Extend CCL documentation in YAZ reference. Describe r=r.
2055 --- 2.0.26 2004/10/01
2057 Fixed MARC->MARCXML conversion to properly deal with
2058 fields, subfields, indicators having non-ASCII characters.
2060 Fixed MARC->MARCXML conversion so that ASCII control characters
2061 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2064 Added YAZ GFS support for conversion from Z39.50 surrogate
2065 diagnostics to SRW surrogate diagnostics.
2067 Bug fix: YAZ GFS did not return schema in explainResponse.
2069 --- 2.0.25 2004/09/30
2071 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2072 now converts recordSchema to elementSetName as well as schema URI.
2074 Fixed bug in COMSTACK that prevented HTTP request packages from being
2077 --- 2.0.24 2004/09/29
2079 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2080 does not require white-space before and after the dash in a range, e.g.
2081 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2084 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2085 due to new GCC removing "redundant" code.
2087 Added yaz-client commands scanpos and scanstep that sets preferred
2088 position and step-size for scan.
2090 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2092 Added CCL utility ccl_qual_buf which parses one or more CCL
2093 spec lines in a buffer.
2095 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2096 of name and value - ignoring empty lines and comments.
2098 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2100 Added odr_get_element_path which returns current element path for an
2101 ODR handle. This utility is useful in error handling or user-defined
2104 Added ODR_PRINT utility odr_set_stream which is is a more generic
2105 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2106 to a write function and pointer to close function. The close function - if
2107 non-NULL - will be called during odr_destroy.
2109 Fixed bug in CCL parser where truncation char was not removed from
2110 right side when truncation=both was in effect.
2112 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2115 --- 2.0.23 2004/08/11
2117 Fix buffer overrun in CQL parser when dealing with proximity (%).
2119 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2120 to UTF-8/UCS conversion is now only based on codetables.xml.
2122 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2124 --- 2.0.22 2004/08/06
2126 Add support for more "commit changes" in ZOOM (uses Extended Services).
2128 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2131 Yet another small fix for configure of SSL.
2133 --- 2.0.21 2004/05/14
2135 Fix SSL libs for configure when --with-openssl=DIR is given.
2137 --- 2.0.20 2004/05/10
2139 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2141 SSL comstack now uses yaz.pem certificate file on server side
2142 by default. Certificate filename can be configured by calling
2143 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2145 Fix bug regarding multiple calls to ZOOM_connection_connect.
2147 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2149 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2150 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2152 ZOOM now allows inspection of X509 peer certificate for verification.
2153 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2155 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2156 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2157 as "modular" but it simplifies things.
2159 Added cs_get_peer_certificate to that returns peer X509 PEM.
2161 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2162 NULL if SSL is unavailable.
2164 Documentation about MARC decoding tools.
2166 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2168 --- 2.0.19 2004/03/30
2170 Rename CHANGELOG to NEWS to follow GNU style packing.
2172 Fix bug with missing initialization of member in init_diagnostics.
2173 This bug affects threaded version of GFS server.
2175 --- 2.0.18 2004/03/20
2177 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2180 Ensure zlib.dll is packed with Windows install.
2182 --- 2.0.17 2004/03/17
2184 Fix encoding of xsd:string to use text instead of CDATA.
2186 Fix endless loop in CQL parser with unbalanced ".
2188 Use a more compact way to store MARC-8 conversion tables.
2190 --- 2.0.16 2004/03/16 Debian only
2192 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2195 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2200 --- 2.0.15 2004/03/01
2202 Another fix for decoding of XML packed records.
2204 --- 2.0.14 2004/02/25
2206 Fixes for Chunked encoding. White space not ignored after length spec.
2208 Update NS and use default NS for SRW diagnostic elements.
2210 --- 2.0.13 2004/02/23
2212 Implement ZOOM_resultset_cache_reset which resets record cache.
2214 Implement ZOOM_resultset_sort which sorts a result set.
2216 Implement chunked HTTP transfer.
2218 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2220 --- 2.0.12 2004/02/16
2222 Added member 'schema' to bend_explain_rr structure so that backend
2223 can specify explain record identifier. Defaults to Zeerex 2.0.
2225 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2227 --- 2.0.11 2004/02/16
2229 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2232 Added init command for yaz-client which sends "extra" init request.
2234 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2235 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2237 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2239 Make ZOOM error code for "invalid query".
2241 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2243 --- 2.0.10 2004/02/05
2245 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2248 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2250 Added option -p <file> to make Generic Frontend Server to write PID file.
2252 Added option -D to put Generic Frontend Server in background on its own.
2254 Make ZOOM C recognize option "password". If unset, "pass" is used
2255 (for backwards compatibility).
2257 Fixed a bug in Generic Frontend Server that could make it crash if a
2258 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2261 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2262 Must be issued before open, in order to be in effect.
2264 --- 2.0.9-6 2004/01/12 Debian/Windows
2266 Make the SRU server more picky WRT unknown params, etc.
2268 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2270 New YAZ client command, options, that sets Z39.50 options.
2272 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2273 options from a string of tokens (one token for each option bit).
2275 Update SRW diagnostic code messages.
2277 --- 2.0.9-5 2004/01/07 Debian/Windows
2279 Handle user defined stylesheet for SRW/SRU.
2281 --- 2.0.9-4 2004/01/06 Debian/Windows
2283 Fix bug in decoding of Content-Length.
2285 --- 2.0.9-3 2004/01/06 Debian/Windows
2287 Fix a bug with decoding of XML packed records.
2289 --- 2.0.9-2 2004/01/05 Debian only
2291 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2293 Fix bug in SRW/SRU diagnostics decoding.
2295 --- 2.0.9 2004/01/05
2297 Fixed bug in Generic Frontend Server which could drop records exceeding
2298 preferred message size. Reported and fixed by Irina Dijour.
2300 Fixed calculation of package size for structured records in Generic
2301 Frontend Server. Reported and fixed by Irina Dijour.
2303 Fixed namespace for SRW/SRU diagnostics.
2305 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2307 --- 2.0.8 2003/12/22
2309 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2310 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2313 CQL changes to reflect recent changes to the specification:
2314 * Documentation talks about context sets instead of index sets.
2315 * Documentation talks about indexes instead of qualifiers.
2316 * The CQL-to-PQF transformer's configuration file now uses
2317 "index.set.name = <attributes>" instead of the old form
2318 "qualifier.set.name = <attributes>". (Both forms are still
2319 understood but the latter is deprecated.)
2320 * CQL terms with no explicit index specified are now interpreted as
2321 cql.serverChoice instead of srw.serverChoice (which of course
2322 behaves exactly the same.)
2324 --- 2.0.7 2003/12/16
2326 MARC conversion can now generate ISO2709 output in another
2327 character set. yaz-marcdump uses this facility if you invoke it
2330 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2331 functions from there can be used from C++.
2333 --- 2.0.6 2003/12/04
2335 Frontend server now transfers memory from decoded packages to stream
2338 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2339 references to show up.
2341 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2342 the ZOOM Abstract API. The older names for the same options are still
2343 also supported for the benefit of old applications.
2345 ZOOM-C supports "implementationId" and "implementationVersion" options
2346 to go along with "implementationName". These allow the user code to
2347 specify identification strings to be sent to servers.
2348 Add OID for the new ExtLite attribute set.
2350 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2351 as requested/supplid by Ere Maijala <ere@atp.fi>
2353 For generic frontend server, reverse the order of
2354 "toolkit-supplied / application-supplied" strings sent as implementationId,
2355 Name and Version. Also, remove the spaces around the slash. This brings
2356 the GFS in line with the behaviour of ZOOM-C on the client side.
2358 Add function ZOOM_scanset_display_term.
2360 yaz-client shows scan displayTerm if present.
2362 Utility yaz-iconv is now installed by default along with the man page
2365 Extend configure check for OpenSSL to use pkg-config where available (such
2368 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2369 server to specify uid/gid/mask for socket using the format
2370 unix:[user=uid,][group=gid,][umask=mask,]file=path
2371 If file= is omitted the existing format is assumed, e.g.
2373 in which case the mask is 0666 (rw for everybody).
2375 Major restructure of YAZ source. All source in libyaz is in src directory.
2376 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2377 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2379 Added man page for utility yaz-marcdump (used to be called marcdump).
2380 yaz-marcdump is installed by 'make install'.
2382 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2383 of incoming package failed.
2385 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2387 Change prototype of odr_perror: add const to message string.
2389 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2391 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2392 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2393 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2394 DNS lookup. There should not be any compatibility problems with this
2395 assuming that blocking=1 or 0 is used.
2397 Fix bad reference in UNIX comstack in function cs_addrstr.
2399 Fix for compilation on AIX.
2401 The generic front-end server (server/seshigh.c) now supports returning
2402 Init diagnostics to the client in User-information-field, in
2403 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2406 --- 2.0.4 2003/09/04
2408 Allow any CQL relation (not just all,any,exact,scr).
2410 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2411 that features the same UI.
2413 Implemented command update0 in YAZ client which is equivalent to
2414 update but uses old of Ext Update ASN.1.
2416 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2417 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2418 Previously no OID was used for this info.
2420 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2421 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2422 returns 'malformed search term' otherwise.
2424 SortResponse member resultCount now set to NULL in sort handler of
2427 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2430 Add three new utility functions for translating OIDs between various
2431 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2432 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2433 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2434 char *oid_to_dotstring(const int *oid, char *oidbuf);
2435 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2437 Reverted modifications for ES Update definition for z_IU0Update
2438 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2439 is back to YAZ 2.0.2.
2441 String value attributes for CCL parser.
2443 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2444 which their FirstSearch server returns in Init responses, sometimes
2445 carrying useful diagnostic information when Init fails. This has the
2446 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2447 "z39.50/oclcui.asn", where its definition is somewhat different from
2448 what OCLC document on their web-site, as required to interoperate with
2451 Support for anonymous authentication in yaz-client. Use the command
2454 * Fix the OID of the Index Data-local "admin" Extended Service from
2455 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2456 the 1000, which indicates a locally-defined OID, was a mistake.
2458 --- 2.0.3 2003/06/20
2460 Fix CCL directive @case handling so that it affects string match for
2461 both CCL keywords and qualifiers.
2463 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2464 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2465 Decoder has been updated with ASN.1 changes as listed in
2466 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2467 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2468 z_IUUpdate, remains unchanged.
2470 ZOOM_record_get may now return a record in a specific character set.
2471 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2472 "from" is the character set of record as returned by target. "to" is
2473 the character set to be returned. If omitted, "to" is UTF-8.
2475 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2477 New ODR utility, odr_getelement, which returns name of element for
2478 which encoding/decoding failed.
2480 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2481 in cases where a required element was omitted.
2483 Bug fix: some MARC8 sequences were not converted.
2485 New ZOOM option "step" which specifies number of records to be
2486 retrieved in one chunk. Used in conjunction with "start" and "count".
2488 SRW support for yaz-client. Use scheme http: to use it, e.g.
2491 yaz-client no longer does (un)intelligent character set conversions
2492 by default. Can be enabled with charset and marc_charset commands.
2494 xmalloc trace fix for 64-bit systems such as DEC alpha.
2496 Solaris 2.6 compile fix.
2498 New function, cql_strerror() translates SRW error codes, as returned
2499 by cql_transform_error(), into human-readable English strings. Used
2500 in yaz-client diagnostics when appropriate.
2502 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2503 converts it into a type-1 query which is sent to the server. This
2504 makes CQL available for use with all Z-servers, as opposed to the tiny
2505 minority that can handle CQL queries themselves.
2507 --- 2.0.2 2003/04/28
2509 New Debian package layout similar to the Redhat Package layout.
2511 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2512 and search result respectively.
2514 --- 2.0.1 2003/04/25
2516 Redhat package is now several packages: libyaz (runtime libraries),
2517 libyaz-devel (development and documentation, and yaz (utility programs).
2518 Package spec file by Morten Bogeskov.
2520 New member 'schema' in struct bend_fetch_rr which the name of requested
2521 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2522 handler MAY set this to reflect the schema of the returned record.
2524 New member 'display_term' in struct scan_entry. GFS now sets member entries
2525 and allocates scan entries to be filled by user scan handler. In previous
2526 version, entries member was allocated by the scan handler. That still works,
2527 but the GFS will ignore member display_term - assuming it was NOT set by
2528 the handler. The fact that the GFS now allocates the entries both allows
2529 for new members and makes a scan handler easier to write.
2531 Fix CQL lex buffer overflow.
2533 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2534 SRU default recordPacking is string.
2536 SRU protocol support for frontend server.
2538 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2540 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2542 Added scan for the ZOOM shell (zoomsh).
2546 * String Identifers for Schemas (Amendment 5).
2547 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2548 Old definition for schema
2549 Odr_oid *schema; /* OPT */
2554 Z_InternationalString *uri;
2555 #define Z_Schema_oid 1
2556 #define Z_Schema_uri 2
2559 * resultCount parameter to Sort Response (Amendment 1).
2560 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2562 Support for SRW 1.0 over HTTP. This is an optional feature and
2563 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2566 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2567 on the same port. SRW SearchRetrieveRequests are mapped
2568 to bend_init,bend_search,bend_fetch,bend_close.
2570 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2572 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2573 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2575 ZOOM connections are SRW based if schem http is used for hostname
2576 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2577 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2579 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2580 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2581 distance=n, order=true/false, relation=le, prox unit=word. If
2582 n is omitted, distance 1 is used.
2584 Fixed problem with C compiler include path in wrong order.
2586 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2587 on Solaris. Patch from Ko van der Sloot.
2589 New MARC decode API. All new functions operate on a yaz_marc_t
2590 handle. The most important new functions are: yaz_marc_create,
2591 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2592 decode and destroy respectively. Decoder can produce formats
2593 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2594 include/yaz/marcdisp.h.
2596 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2597 to UTF-8, UCS-32, wchar_t or Latin-1.
2599 * Prototypes for yaz_iconv_-functions moved to separate header
2600 include/yaz/yaz-iconv.h.
2602 Make a few private functions 'static' in unix.c. This prevents
2603 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2605 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2606 are set when Init Response is received.
2608 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2609 but returns diagnostic set as well.
2611 New function yaz_strerror which is a portable wrapper for
2612 strerror/strerror_r/GetLastMessage.
2614 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2615 is returned for MARC. If type is "oai", then OAI MARC is returned.
2617 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2620 --- 1.9.2 2002/11/26
2622 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2624 Fix bad race conditions on SIGTERM and terminate gracefully in
2627 Move retrieval (data1) module to Zebra since nobody seems to be
2630 Add GRS-1 render for ZOOM using same format as yaz-client.
2632 --- 1.9.1 2002/10/05
2634 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2636 Fix broken ESpec handling in data1 module.
2638 SGML reader parses comments and makes them part of the data1 tree.
2640 Added several type casts so that YAZ compiles as C++ code.
2642 ZOOM didn't handle PDU encoding failures properly.
2644 Added more Bib-1 diagnostics (approved extensions).
2646 GNU configure: better check for iconv.
2648 More portable use of accept, getpeername. Check for socklen_t. Use
2649 int/size_t if socklen_t is not defined.
2653 PQF parser rejects bad queries - including those with extra
2654 characters in them. PQF parser used to silently ignore that.
2655 Cleaner API for PQF added, which allows you to get detailed
2656 error information for bad queries (see yaz/pquery.h).
2658 Fixed bug in ZOOM_record_get for type "database".
2660 Implemented mini iconv library supporting conversions between
2661 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2663 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2665 --- 1.8.9 2002/08/20
2667 Fixed ZOOM C record cache so that preferredRecordSyntax and
2668 elementSetName is used to check for already fetched records.
2670 --- 1.8.8 2002/08/02
2672 Added three members in bend_initrequest structure to facilitate
2673 character set negotiation.
2675 Fixed a bug in frontend server that could cause indefinite
2676 loops under rare conditions.
2678 Revised character set utilities (charneg.h) so that encoding
2679 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2681 For PQF, directive @term <type> sets term type for Scan/Search.
2682 Here <type> is general, string, numeric, null. The term type
2683 is inherited - just like @attr.
2685 New call odr_set_charset that sets character set conversion for
2686 international-strings on a ODR stream. Prototype is:
2687 int odr_set_charset(ODR o, const char *to, const char *from);
2688 The InternationalString is still represented as C string in YAZ
2689 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2690 won't). On the protocol level, you can use any encoding.
2692 Support for UNIX sockets in ZOOM.
2694 Solaris recv sometimes returns errno == ENOENT. It is treated as
2695 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2697 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2698 both client and server. Code by Morten Bogeskov.
2700 --- 1.8.7 2002/05/22
2702 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2703 that they can be used directly from Visual Basic. You must recompile
2704 your windows APP if you're using ZOOM.
2706 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2707 Commands "lang" and "charset" sets language and character set respectively.
2708 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2709 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2711 Attributes from multiple CCL fields may be OR'ed rather than merged
2712 using directive "@field or". Fields are still merged by default -
2713 equivalent to "@field merge".
2715 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2718 Fixed bug in zget for parameter ExtendedServicesResponse.
2722 --- 1.8.6 2002/03/25
2724 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2726 Client displays USR.1:SearchResult-1 (hits per term).
2728 Additional Search Info for search in Generic Frontend Server.
2730 Fixed CCL parsing of "field=s".
2732 WIN32 installer - using the excellent NSIS software from nullsoft.
2734 Fixed CCL parsing of "field = - <number>".
2736 Added function yaz_marc_decode that decodes MARC for line mode
2737 display or XML (similar to that used by JZKit).
2739 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2740 Z39.50. But ISO/ILL was, however.
2742 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2743 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2745 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2746 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2748 --- 1.8.5 2002/02/03
2750 New YAZ client features: Command completion and new commands:
2751 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2752 Code provided by Jacob Poulsen.
2754 New call oid_trav, that visits all registered OIDs via callback.
2756 Function ZOOM_record_get now returns const char pointer rather than
2757 void pointer. It saves a lot of type casts.
2759 For YAZ client, command "auth" now allows you to set authentication
2760 in IdPass style. It is enabled when three tokens are given - order
2761 is user, group and password.
2763 Fix memory leaks in MARC record handling for ZOOM.
2765 New option for YAZ client, -k <kilobytes> that sets
2766 maximum record size. Similar to -k option for generic frontend
2767 server and yaz-ztest.
2769 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2771 Prefix query parser reports "fail" when bad attribute set is given.
2773 Fix in MARC decoder. Proximity logging. Fix for attribute set
2774 in scan handler for server. Patches by Shigeru Ishida.
2776 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2779 Configure option --with-openssl=<dir> now works when a directory is
2780 specified. Patch provided by Morten Bogeskov.
2782 New option for YAZ client, -u <auth>, that sets authentication.
2784 ZOOM fix: error information was sometimes "missing", since error
2785 was cleared/reset too when it shouldn't.
2787 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2789 --- 1.8.4 2002/01/04
2791 Scan for ZOOM API. New object ZOOM_scanset. New functions
2792 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2793 ZOOM_scanset_destroy.
2795 New ZOOM function, ZOOM_connection_last_event, that returns type
2796 of last event (such as "receive data", "send data", "apdu received",
2799 New ZOOM option, schema, that specifies schema for retrieval.
2801 New CCL feature. Qualifiers can be aliases for one or more
2802 other qualifiers (if more than one is given, OR is used).
2804 ZOOM uses named result sets if target supports it.
2806 Two new YAZ client commands: . (dot, which sources a script of YAZ
2807 client commands), and ! (to execute shell command.). Implemented
2810 Working on Debian packages.
2812 --- 1.8.3 2001/11/19
2814 YAZ client enables named result sets only if target supports it.
2816 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2818 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2819 with key="host" to get same result.
2821 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2822 Function Z3950_resultset_record(s) returns references to records
2823 "owned" by resultset. To become owner use Z3950_record_clone.
2825 Function z_ext_record handles Extended Services. Thanks to
2828 --- 1.8.2 2001/11/12
2830 CCL Parser fix: ignore token comma when dealing with and-lists.
2832 Documentation updates for COMSTACK.
2834 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2835 Changed prototype Z3950_records. For some functions, int parameters
2836 were changed to size_t.
2838 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2841 New MARC decode/display function, marc_display_exl, which properly rejects
2842 non-ISO2709 records. YAZ client uses it.
2844 --- 1.8.1 2001/10/29
2846 Fix bug: local attribute set wasn't set correctly in PQF strings.
2850 * Old Z39.50 codecs no longer supported.
2852 Added ZOOM C binding. See http://zoom.z3950.org/
2854 Renamed states for COMSTACKs to avoid confusion with events.
2856 Implemented cs_look and proper cs_rcvconnect.
2858 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2860 Configure detects POSIX threads on OpenBSD.
2862 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2863 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2865 When error is returned from present handler, non-surrogate diagnostic
2866 is returned in present response (and fetch handler is no longer called).
2868 * Minor adjustments to pquery parser (PQF). Token characters may be
2869 escaped by using backslash (C-style).
2871 PQF parser allows string attribute values to be specified. For @attr,
2872 non-numeric characters after the equal-sign are treated as strings
2873 (e.g. @attr 9=title).
2875 CCL trunction character may be defined (@truncation in file)
2877 * function zget_ExtendedServicesRequest sets waitAction to
2878 waitIfPossible (was wait).
2880 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2883 CCL operator names may be set in field definition files (CCL_bibset).
2884 See ccl/bib1 for an example.
2886 Fixes in ASN.1 compiler for C++ compatibility.
2888 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2889 and "op_or" to avoid conflict with C++.
2891 Fixed problem with GNU readline detection on Redhat 7.0.
2893 Added step-size for Scan backend handler.
2895 Fixed bug that made the frontend server crash when no attribute
2896 set was specified for scan.
2898 Front-end server automatically switches to original working directory
2899 when installed as an NT service. Previously -w had to be specified to
2902 Added extended attributes for retrieval module (data1), so that data1
2903 records carry d1_readXML/SGML attributes. d1_read also supports
2904 null-data rules ( <tag/>)
2906 On UNIX when POSIX threads are available, a separate library libyazthread
2907 is created. Programmers should link with that library and the yaz library
2908 when using threads. The reason for the split was that some applications
2909 on Linux, such as Apache, doesn't work well when using shared objects that
2912 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2913 (or any frontend server) in SSL mode by specifying ssl: followed by
2914 address. Only tested on UNIX.
2916 Added feature for CCL module. Virtual structure s=al or s=ol generates
2917 and-list and or-list respectively instead of phrase search.
2921 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2922 log_mask_str. This was done to avoid name conflicts with other libraries
2923 (such as other PHP extensions).
2925 Added raw OID member for preferred record syntax (request_format_raw)
2926 and returned record syntax (output_format_raw) for backend fetch method.
2928 Config file yaz-config now accepts options so that it returns specific
2929 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2931 Shared library support for UNIX using GNU libtool.
2933 * Modified backend interface. Request/Response struct's replaced by
2934 one read/write C struct. For example bend_fetchrequest and
2935 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2936 Every handler - even search has to be registered in bend_init
2937 handler. This means that the YAZ library no longer refers to
2938 external functions and it makes it possible to make the whole
2939 thing a single DLL/SO.
2941 Added Segment handler for backend server.
2943 Added Zmbol/Zebra administrative functions to YAZ client.
2945 Threaded frontend server on UNIX (when POSIX Threads are available).
2946 Starting the server with option -T enables multi-threading.
2950 Added configure option --enable-comp/disable-comp to control use
2951 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2952 located in sub directory asn.
2954 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2955 in ${exec_prefix}/bin along with the other programs yaz-client and
2958 GNU automake used to maintain makefiles.
2960 Added several OID's.
2962 Changed retrieval module so that we can load records with no abstract
2963 syntax defined. Tagpaths in these records are fully composed of string
2966 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2970 On UNIX, the generated makefile now supports a proper 'make install'.
2971 The prefix can be set via GNU configure to set the install location
2972 (default is /usr/local).
2974 * YAZ programs client and ztest were renamed to yaz-client and
2975 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2976 locations, such as /usr/bin,/usr/local/bin,etc.
2978 * YAZ Header files were moved from include to include/yaz. YAZ Header
2979 files are referred to as include <yaz/log.h> rather than <log.h>.
2980 The YAZ include path (-I ..) is therefore the same as before. Programmers
2981 should update their #include statements or use -Ipath/include/yaz
2982 instead. The main motivation for doing this change is that YAZ header files
2983 can be installed in "standard" locations /usr/include,/usr/local/include
2984 without introducing conflicts, since ALL YAZ header files are stored
2985 in subdirectory yaz (under /usr/include for example).
2987 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2988 rather than project/workspace files. We switched because project files
2989 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2992 Changed name of logging function, logf, to yaz_log, to prevent name
2993 clash with some math-log functions. The YAZ header log.h defines logf
2994 to yaz_log (#define) so there should be no incompatibilities by this
2997 Added bend_start/bend_stop handlers for server. These handler are
2998 called on start/stop of server. For windows they are called whenever
2999 a service is started/stopped.
3001 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3002 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3003 in util/yc.tcl. The auto-generated C code structures are, in a few
3004 cases, incompatible with the old decoders. There are differences in the
3005 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3006 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3007 The preprocessor variable ASN_COMPILED is defined when the compiled
3008 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3009 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3010 wish to use the old encoders/decoders you can specify --disable-yc
3013 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3014 version so that it supports both new - and old version of DB Update
3016 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3017 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3018 change. The name parameter can be set to 0 in which no name is specified
3019 for the construction. The macros odr_implicit and odr_explicit sets name
3020 parameter to zero for the construction involved. New macros
3021 odr_implicit_tag and odr_explicit_tag are similar to the others,
3022 except that a name parameter is added. For programmers' that don't use
3023 ODR they probably only need to change the call to z_APDU and z_External.
3025 Added access control facility by interfacing the TCP wrapper library.
3026 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3027 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3028 name of the daemon and enables the access control as specified in
3029 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3031 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3032 den Dool <H.M.vdnDool@kub.nl>.
3034 Added reference ID parameter to most functions in server API - refer
3035 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3037 Changed name of ccl library to libccl.a (was ccl.a).
3039 Fixed bug in decoder for Explain (Category TargetInfo).
3041 Added support for GNU readline in client. Thanks to Jacob Poulsen
3042 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3044 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3045 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3046 IMPLEMENTATION! This change was made to the development version before
3047 the ZIG decided to retract the amendment. If any users MUST be
3048 compatible with the original Update definition, PLEASE CONTACT US, and
3049 we will include a separate definition corresponding to the old Update
3050 ES. Note that because of the change to the ASN.1 of the
3051 TaskPackageRecordStructure we cannot define a single structure that
3052 will support both versions.
3054 * Added const modifier to buffer parameter for some ODR/BER encoding
3055 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3056 completeWAIS, odr_dumpBER.
3058 Fixed bug in client.c which caused a crash when a scanResponse didn't
3059 contain positionOfTerm.
3061 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3062 * will cause an error in a client if a non-YAZ target sends both a
3063 * list of Scan entries and non-surrogate diagnostics.
3065 Retrieval module enhancements. Tag sets may be typed in the reference
3066 to it. From the .abs-file the "tagset" directive takes a third optional
3067 integer type for the tag set referenced. From a .tag-file the "include"
3068 directive takes a third optional type as well. The old "type" directive
3069 in the tag set itself is still recognized but acts as the default type
3072 Backend interface change. Individual Scan terms returned from bend_scan
3073 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3074 in include/backend.h.
3076 Retrieval module enhancements. Multiple tag sets and attribute sets may
3077 be specified in abstract syntax specs. Revised the error/warning for
3078 logging messages reported by the retrieval module when reading the
3081 Object Identifier system (oid_..) changed. The API is backwards
3082 compatible but the oid-routines now allocates new OID's when needed.
3083 Raw OID's may be specified in oid_getvalbyname.
3085 YAZ now uses GNU configure to generate Makefile(s).
3087 * Minor changes in some of the member names of DeleteResultSetRequest and
3088 DeleteResultSetResponse. See include/proto.h.
3090 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3091 and added member 'languages' in TargetInfo (which was missing).
3093 Changed the way attribute sets are handled in the retrieval
3094 module. These are now cached, just like the abstract syntaxes
3097 Changed YAZ so that it links with compiled ASN.1.
3099 Added Explain-schema definitions and mapping routines. The following
3100 Explain categories have been implemented: AttributeDetails,
3101 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3103 Fixed minor bug in Windows version of Server Library.
3105 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3107 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3109 Added EXTERNAL: UNIverse Resource Report (non-standard).
3111 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3112 ENUMERATED and SET OF.
3114 * Added 'const' to some of the char pointer arguments for the
3115 functions, data1_read_node, data1_getelementbytagname,
3116 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3119 Fixed bug in data1_insert_taggeddata - the last_child member of
3120 parent wasn't initialised.
3122 * Changed data1_read_record and data1_read_node so that the supplied
3123 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3124 doesn't refer to any parts of the "SGML"-buffer.
3126 Fixed bug in server library (Windows version of statserv_remove).
3128 * Changed code so that it compiles as C++. The type definition
3129 of Odr_fun which is a member of Odr_arm was changed. The result is,
3130 that an explicit typecast is needed for the fun pointer when
3131 using Odr_arm - as in:
3132 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3134 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3136 Implemented the new structured date and time definition as approved
3137 by the ZIG. Added schemaId element to the specificTag in Espec-1
3138 (also approved at the last ZIG). Thanks to RVDM.
3140 Added some Object identifiers (RVDM).
3142 Changed the Update Extended Service (RVDM).
3144 Added command "refid" to client which specifies referenceId for
3145 the following requests.
3147 Implemented extended service handling for server. See ztest.c
3148 for an example as well as backend.h. New handlers are registerd
3149 in the Init handler.
3151 * Changed interface for sort in server.
3153 Added new members to statserv_options_block. It allows a server
3154 to read options from another source than just the command line. Thanks
3155 to Charles Woodfield.
3157 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3158 renamed to zboolean. Some C++ compilers complained about the name.
3160 Minor changes to gils.abs. Added index 's' (sort) on title
3161 and date/time-last-modified.
3163 --- 1.4pl2 1998/1/30
3165 Fixed bug in server library regarding inetd mode (-i). This bug
3166 was introduced by release 1.4.
3168 --- 1.4pl1 1998/1/29
3170 Added sort facility in client and backend server interface.
3172 Fixed problem with dependencies in Makefile(s).
3174 Fixed bugs for encoders/decoders of extended services and
3177 Implemented sub-tree feature for schemas. Sub-trees are
3178 referenced in *.abs-files. See explain.abs for an example
3179 of the use of this feature.
3181 Modified bib1.att; local attributes for ANY didn't include
3182 ANY itself (only affects use of the retrieval module).
3184 Fixed bug in plain SGML reader in function data1_read_node:
3185 tags with prefix "var" was incorrectly interpreted as variants.
3187 Added feature "sub-schemas" to enable references to - and definitions
3188 of - group of elements.
3190 * Removed member parent from type data1_element (in data1.h).
3192 Implemented function odr_nullval() that returns the value of
3195 * Removed member num_children from data1_node (in data1.h).
3197 Made NT service interface part of the server library. The
3198 function statserv_main uses the NT service when required and
3199 calls the statserv_start / statserv_close routines.
3201 Routine zget_SearchRequest and zget_PresentRequest fills
3202 resultSetName/Id member with "default" instead of "Default".
3204 Fixed memory leak in server. Request queue member wasn't freed.
3206 Fixed nmem_exit so that memory is freed.
3210 Revised the CCL parser utility to be thread safe.
3212 Added function, oid_ent_to_oid, to replace the function
3213 oid_getoidbyent, which is not thread safe.
3215 * Added nmem_init and nmem_exit to initialize and release
3216 NMEM resources. Function nmem_init should be called once in the
3217 initial thread before NMEM/ODR is used. statserv.c and client.c
3218 have been changed accordingly. The change was necessary to make
3219 NMEM thread safe. The NMEM memory pool is shared amongst threads
3220 in a process. Unix-based applications will still work fine without
3223 Added NT Services interface for the the Z39.50 (statserv) Server.
3224 Refer to the ztest.c source on the usage.
3226 Windows 95/NT port using MSVC5.0. Project files are included in the
3229 * Defined new 'global' handle for the retrieval (data1) system. The
3230 new handled, data1_handle, describes the state of the data1 system.
3231 This handle is passed as first argument to virtually all
3232 data1 related routines. The functions data1_create and data1_destroy
3233 creates and destroys a data1 handle respectively.
3235 Added ODR encode stream member to all backend request structures
3236 init, search, scan etc. This stream should be used to allocate all
3237 memory used for the response when thread safe operation is needed.
3239 Changed the comstack utility, cs_addstr, to be thread safe. The
3240 returned hostname string returned by the function is now part the
3243 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3244 function. The cs_straddr takes a COMSTACK handle as argument, so this
3245 function must be used after cs_create and before bind/connect.
3246 This function is thread safe.
3248 Moved test server to 'ztest' directory - generic server code still
3249 in 'server' directory.
3251 Made prefix query (pquery.c) utility thread safe.
3253 Added new function modifier YAZ_EXPORT to 'export' public DLL
3254 functions when using windows (see include/yconfig.h).
3256 Added definitions to the OID database (util/oid.c) (RVDM).
3258 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3260 Added call to ccl_rpn_delete in client program.
3262 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3263 release of RPN structure.
3265 Added support for C++, headers uses extern "C" for public definitions.
3266 With input from RVDM.
3268 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3269 Thanks to Ronald van der Meer (RVDM).
3271 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3273 Added support for private extensions to the OID database
3274 (oid_setprivateoids()). Thanks to RVDM.
3276 Added optional, physical ANY (key replication)
3278 Fixed null-reference problem in GRS-1 output filter.
3280 Proximity operator added to Prefix Query Format (PQF).
3282 In test client command "base" accepts multiple databases.
3284 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3288 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3290 Smallish bug-fixes in the new encoders/decoders (explain).
3292 Bug fixed in DeleteRequest.
3294 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3296 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3298 Added SOIF syntax (using private OID for now) to retrieval module and client.
3300 Added Update extended service.
3302 Added SearchResult-1 additional info structure.
3304 Added optional CCL (ISO8777) interpreter as separate module. Available
3307 --- 1.2 1996/6/10 (1st anniversary release)
3309 Added Summary record syntax. Lightly tested.
3311 Added OPAC record syntax. Untested.
3313 Added ResourceReport service encoders/decoders. Untested.
3315 Fixed bug in z_Unit - wrong tagging on unitSystem.
3317 Fixed bug in the DiagRecs decoder.
3319 Added options for max PDU size and session timeout to frontend-server.
3321 Added documentation of query-language parsers and other supporting utilities.
3323 [frontend-server] Added Attribute set to the bend_scanrequest API.
3325 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3326 surrogate diagnostics were generated.
3328 [retrieval] Allow multiple local values for attribute.
3330 [retrieval] Allow multiple attributes per element in .abs files. index type.
3332 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3334 --- 1.1pl2 1996/4/10
3336 Minor changes, mostly specific to Zebra's requirements (retrieval)
3340 Repaired bug in frontend server when running multiple listening
3341 endpoints in dynamic mode.
3343 z_External() now won't break if a known, ASN.1 value comes encapsulated
3344 in an octet-string. The value will pass through unmodified in an Odr_oct.
3346 Added a bit of code to the demo client to decode & display
3347 ASN.1-structured records represented in the octet-aligned branch of
3348 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3350 Added z_ext_getentbyref() to the ASN module. Doc updated.
3352 * Completed the SCAN definition in the ASN module. This may break SCAN
3353 code based on older YAZ-versions at compile-time. The fix is easy -
3356 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3357 under the SCAN definition. Remember to initialize this, server-people.
3359 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3360 that this does not extend to ODR and ASN.
3362 Comstack allows insertion of established socket (primarily for
3363 inetd-operation of servers). Doc updated.
3365 Front-end server can now start from the inetd in TCP mode. Doc
3368 --- 1.0pl4 1996/1/24
3372 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3373 the rank and record number.
3375 Adjustments to the frontend server.
3377 Fixed diagnostic BER dumper. It ignored the file argument.
3381 Various changes to retrieval module.
3383 Changed the union discriminators of the protocol files from enums to
3384 ints paired with #defines.
3386 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3389 *Changed operator in the RPN structure to 'roperator', again to avoid a
3392 Fixed problems in Explain decoders/encoders.
3394 --- 1.0pl2 1995/12/6
3396 Memory bug in log module fixed.
3398 --- 1.0pl1 1995/12/5
3400 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3402 Bug in Explain DatabaseInfo module fixed.
3404 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3408 The shift to v1.0 signals that we now consider the *core* functionality
3409 of YAZ reasonably stable (the core being more or less equivalent to
3410 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3411 tested (Explain not at all - though that will happen soonish).
3413 Minor changes to code to support Windows port.
3415 Various minor changes after we're getting to use GRS-1 & co. more.
3417 Added Espec-1 format.
3419 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3420 of the protocol and it cannot be selected when encoding (maps into 'string'
3421 when decoding). Needed to talk to some servers.
3423 Demo client can request simple element set names.
3425 Added Diagnostic Format encoders/decoders.
3427 Added simple Close handling to frontend server (no hooks for resource
3428 reporting yet), and demonstration client.
3430 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3432 --- 1.0b3 1995/08/24
3434 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3435 handled incorrectly when records were requested in the searchResponse. This
3436 will only affect you if you use the frontend-server.
3438 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3439 Test-client will ask for and print GRS1. Ztest will return dummy records
3442 Added Explain encoders/decoders to the service-level API. Untested.
3444 Added Extended Services: Item Order encoders and decoders to the Service-
3445 level API. Untested. We could use a recent copy of the pertinent bits
3446 of the ILL protocol to add those bits.
3448 Added diagnostic format 1 encoders/decoders to the service-level API.
3451 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3452 odr_cons.c, which causes a more correct output.
3454 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3455 was always set to 0 when no records were requested in the searchRequest.
3457 * Added better external-handling. This shouldn't harm old code that
3458 *encodes* externals. It can break code that looks for a
3459 'single-ASN1-type' representation, since those types that are known
3460 are now decoded immediately. Look at the SUTRS sample code in
3461 seshigh.c and client.c. Documentation updated.
3463 Handling of structured records in bend_fetchresponse. Length -1 marks
3464 structured record, type is deduced from format field.
3466 --- 1.0b2 1995/06/27
3467 Fairly quick maintenance release to add SUTRS support.
3469 Fixed handling of SUTRS records in the demonstration client.
3471 * Added format field to the bend_fetchrequest and bend_fetchresponce
3472 structures of the backend API (frontend server). When the record is
3473 returned, the value of the format field is mapped to an OID. The
3474 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3475 of the record. The special value VAL_NONE in the bend_request means
3476 that no specific format was requested by the client. Documentation
3477 updated accordingly. Test server (ztest) will return a fixed dummy
3478 SUTRS record if your client requests SUTRS.
3480 Documentation updated accordingly.
3482 You can now set external libraries and RANLIB support in the top-level
3486 First public release.
