3 Add pz:redis option for ZOOM caching using redis. This is an alternative
4 to memcached. Requires YAZ 5.2.0 to work.
8 Re-ingest native facets PAZ-934
10 Fix medium override for solr-pz2.xsl.
14 Fix URL with leading http:// not working PAZ-933
16 Build packages for Ubuntu Trusty Tahr 14.04 LTS
18 cf.xsl: handle medium override AND md field
22 sortmap relevance always uses increasing=1. PAZ-930
24 solr-pz2.xsl: ensure medium is also applied if Solr record do not
27 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
28 this code is only executed once.
30 Fix typos is sortmap documentation.
32 Doc: fix misplaced variablelist tag.
36 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
37 It's been like that since version 1.1.1 from August 2009.
39 Add support for result-set caching via memcached. See description of
40 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
42 Add support for a <metadata> container tag. Patfh from Sven Porst.
44 Add support for XInclude in main configuarion file. Patch from Sven Porst.
46 Add client_{lock,unlock} before call to non_block_events in
47 connection_continue. Problem is that if non_block_events fire records,
48 then we will not unlock client at all. And as a result, a dead-lock
53 Avoid removing slash and other characters for generic metadata that
54 looks like a URL (contains ://). PAZ-915
56 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
58 Cluster merge fixes. PAZ-901
60 Set client state to "working" when waiting for DNS resolver. PAZ-907
62 Log when session terminates. PAZ-905
64 Fix LSB/HS conformance for /etc/init.d/pazpar2 PAZ-904
65 Debian: add support for /etc/init.d/pazpar2 status
69 Fix 'Record Missing' for command=show PAZ-903
71 Preserve order of records within cluster PAZ-902
73 testing: use yaz-ztest -V if possible and use YAZ in sibling directory
76 Allow clustered records to be ingested during retrieval. PAZ-900
78 Fix void function error which cannot return a value.
82 SRU pz:authentication="a/b" may end up as x-username=a%2Fb PAZ-899
84 Upgrade to debhelper version 7 PAZ-898
86 Package with libyaz5 PAZ-897
88 Better error message for CCL parse errors PAZ-887
92 New target setting: pz:authentication_mode. PAZ-896
94 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
96 Strip #-suffix for ZOOM URLs. PAZ-892
100 Fix issue with hanging show/bytarget. Could happen if new search was
101 fired with filter before show from previous show completed.
103 Add 'date' handling for solr-pz2.xsl.
105 --- 1.6.33 2013/08/13
107 pz:authentication may carry user group password. If pz:authentication
108 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
109 authentication. Two forms are allowed
112 If no blanks are present, open authentication is in use (as before).
114 Fix {prev,next}recid elements that are returned by record
115 command. These were incorrect in versions 1.6.23 thru 1.6.32.
117 --- 1.6.32 2013/06/14
119 Experimental support for snippets. If argument snippets=1 is given
120 for command record or show, the text will include <match>-tags for
121 those area that matches.
123 Fix memory leak WRT client structures (incorrect inc ref count).
125 Log when a HTTP response is serialized and the time elapsed.
127 New command, service, which returns current service XML in use for
130 --- 1.6.31 2013/05/24
132 Local limit for fields of type "generic" (ie text fields) are
133 now normalized by mergekey rule before comparison takes place.
134 Before, no normalization took place and comparsion was, thus, exact.
136 New facility: dynamic rank , which allows ranking to be changed
137 for an existing result set. The rank can be set for search or
138 show. This overrides the rank for metadata elements (which fields
141 New facility:dynamic mergekey , which allows mergekey to be changed
142 for an existing result set. The mergekey can be set for search or
145 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
146 Also, allow ports to be given as names (not just integers).
147 Fix @-notation on systems that don't support IPV6 sockets.
149 --- 1.6.30 2013/04/26
151 Add MasterKey Connect configuration. Refer to section "non-standard
152 databases" for more information.
154 Allow timeformat for log to be specified with option -m (as Metaproxy
157 New Debian package pazpar2-dbg.
159 Fix NULL ptr reference of se->relevance. If a new search is initiated
160 and a CCL query fails to parse, Pazpar2 could crash.
162 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
163 existed in 1.6.29 only.
165 --- 1.6.29 2013/04/05
167 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
168 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
169 changed by setting "host" attribute for the "listen" element.
171 Change semantics of pz:extendrecs. Allow for repeated fetches .
172 pz:extendrecs is now the number of extra records to fetch (was total
175 --- 1.6.28 2013/03/21
177 Fix hang or memory violation if show occurred before a search. (not that
178 it makes much sense to perform a show before a search).
180 --- 1.6.27 2013/03/08
182 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
185 --- 1.6.26 2013/03/08
187 New pz:metadata attribute, empty="empty-value" for Pazpar2's
188 internal representation. With this attribute, Pazpar2 treates an empty
189 pz:metadata type as having the value for "empty" - if empty.
191 New setting, pz:extendrecs, which triggers extended fetch of records
192 for a database beyond pz:maxrecs for a show command.
194 Fix warning that was falsely issued for "missing limitmap".
196 Log message for Pazpart start/stop changed. Now using same style as
197 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
199 --- 1.6.25 2013/02/07
201 Fix hang of 2nd command=show with esn/syntax given.
203 --- 1.6.24 2013/01/18
205 New merge attribute type: 'first', which takes all metadata fields
206 from first target that returns the particular field.
208 --- 1.6.23 2013/01/02
210 Extend info command with hostname and YAZ SHA1
211 Indent results for both command stat and info.
213 Allow limit on merged content. The new configuration metadata
214 element, limitcluster, configures that a metadata element (name) be used
215 as limit name for search. Applies to the whole service (ie all targets),
216 unlike pz:limitmap which is configured per-target (database).
218 New feature: limitmap local:* matches against all metadata fields.
220 Allow repeated list in limitmap spec . Separated by comma. For
221 example: value="local:title,rpn:@attr 1=4".
223 New element <message> in bytarget response. Holds diagnostic message
224 of code (say 'Unsupported Use Attribute' for Bib-1 114).
226 Improved logging for record ingestion failures.
228 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
229 when YAZ is compiled without ICU support.
231 --- 1.6.22 2012/10/11
233 Requires YAZ-4.2.40 to support native solr support.
235 Fix and improve logic handling whether or not to re-do search on sort
236 order changes. A sort order with change in ascending/descending only
237 whould not trigger a new search, which is required for targets with
238 native sorting capabilities. Each client is now checked if instructions
239 (sortmap) exist for native sorting and only client that does requires
240 it is researched. Other clients is just re-ingesting the records,
241 they already have. The resultset is now cleared if any researching
244 Connection sharing between session has broken since version 1.6.8 with
245 introduction of logic that would minimize searching if pazpar2 could
246 detect this based on same query and limits and partly sort order.
247 This could lead to segementations violations.
249 Added a chapter in the manaul about relevance ranking.
251 --- 1.6.21 2012/09/24
253 Rank tweak: follow=number will increase mult by number if two terms
254 occur next to each other; number-1 if they are one term apart , .. 0
255 if they are number a part (all in order). Default is 0 (following
256 terms has no effect).
258 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
259 value given by lead and l is length from beginning of field where
260 term occurs (l=0 for first term, l=1 for second term, ..). Default
263 Rank tweak: length=strategy. length="linear" if mult is to be divided
264 by length (existing, default behavior), length="log" if mult is to be
265 divided by log2(1+length), length="none" if mult is not to be affected
268 --- 1.6.20 2012/09/21
270 Rank algorithm details may be printed as part of show response in
271 element <relevance_info>.. This is only printed if <rank debug="yes"/>
274 Record as returned by show/record command have a minimal indentation
275 which makes things human-readable.
277 New configuration of default sorting criteria (sort-default) in
278 service definition. If no criteria is defined it will be as before
281 Search command now supports sort parameter just as the show command.
282 If no parameter is give, it will use the service sort-default value.
284 --- 1.6.19 2012/09/18
286 Rank algorithm skips strings that gets normalized to empty string.
287 For example, & and ! could map to the empty string. The weight for
288 those terms is now 0 (as if they were not part of the query).
290 Rank algorithm does not use CCL from limitmap; only from the query
291 parameter (user query).
295 --- 1.6.18 2012/09/17
297 Rank algorithm configurable by 'rank' element inside service. So far
298 only, attribute 'cluster' is recognized. If cluster="yes", multiple
299 records inside a cluster boosts higher than single records. This
300 is default behavior and existing behavior. cluster="no" takes the
301 average score of each record in a cluster.
303 --- 1.6.17 2012/09/05
305 Fix bad re-use of connections (connections with changing proxy should not
308 --- 1.6.16 2012/08/22
310 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
311 resultset and sorting when the sort order is position. However this will be done on
312 every client poll, which will make pazpar2 continuing reset and fetching.
313 It should only be done on FIRST request where the sort order change.
315 Fix an issue on suggestion option: Also disable suggestions on empty string.
317 Clean up in turbo marc stylesheet.
319 Remove the hardcoded size of termlists.
321 --- 1.6.15 2012/06/27
323 New facility: ccldirective may be given in service definition. Allows
324 CCL parsing to be customized a bit, such as defining names of operators
327 New facility: raw record by checksum, rather than offset. The record
328 command optionally takes checksum which identifies certain record from
331 New facility: per field ranking. Rank may be given as M [F N] where
332 M is default rank and N is rank for CCL terms from field F.
334 --- 1.6.14 2012/06/04
336 Fix for IE7/8 in pz.js
338 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
340 Lower log level some places.
342 Remove some invalid test results.
344 --- 1.6.13 2012/05/23
346 Introducing a version=2 parameter for show, termlist and bytarget commands.
347 This enables pazpar2 to return approximation on hit and count count when
348 doing record filtering using the limit parameter on search and a
349 limitmap with a value of "local:"
351 Setting pz:xslt may embed local XSLT as an alternative to referring
353 Value is not CDATA but XML nodes embedded, so escaping is not necessary
354 but a root element *must* be present. For example:
355 <settings target="target="z3950.indexdata.com/marc">
364 Metadata field rank may given by XML internal document (pz:xslt
365 result). If rank is not given, the rank from service description is
368 Metadata field can now configured a default limitmap and facetmap.
369 Setting limitmap to "local:" would work for all kind of targets, but would
370 prob. not be the optimal solution. But at least better than the default behavior
371 of pazpar2 where no filtering is done.
373 A service definition can now also contains <set/> that defines service-wide
374 settings. These will override server-wide sets and will be overridded by
377 New setting, pz:present_chunk, that specifies number of records to fetch
378 at a time. Zero will disable chunkation; will fetch max_records at once.
380 --- 1.6.12 2012/03/14
382 Revert the format change in termlist response, that could break
383 some clients / UIs since they were expecting an (empty) element
384 if no facet values was found.
386 --- 1.6.11 2012/03/07
388 Revert the behavior of returning errors when unable to block
389 on termlist, bytarget and search, when unable to block due to
390 other block. The client will now receive a regular response,
391 but it will be logged in the server. A parameter (report) is
392 added to change behavior to return error response or WARNING
393 status message. Consider this "API" as private, as it is mostly
394 untested and could be changed in future releases.
396 Fix spell error in pz2.js fix in 1.6.10.
398 New Marc2TurboMarc.xsl (contribution from Sven Porst).
399 Can solve the missing marc21.xsl updates in some cases.
401 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
402 substring (contribtion from Sven Porst)
404 marc21.xsl: fix 1-based substring call
406 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
408 Add test_termlist_block to test suite
410 --- 1.6.10 2012/02/23
412 Fix SEGV for invalid PQFs and SRU/SOLR targets
413 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
415 Fix pz2.js: "null object" due to change in in bytarget result XML.
417 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
418 Added this normalization to the other subject-long fields (d6xx),
419 where it was missing.
421 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
422 Still differences around medium and holdings. marc21.xsl is not
423 longer active used by Index Data, and should be considered unsupported.
424 Use tmarc.xsl instead.
428 Fix SEGV that could occur for failed connections.
432 Fix bug for command sort that could return no results for active clients
433 (from previous search). This bug was present in 1.6.6-1.6.7.
435 Fix bug in results that could include results that should have been
436 filtered out. This bug was present in 1.6.6-1.6.7.
440 Fix bug introduced in 1.6.6 where a connection re-use could stall
443 Local filtering may now specify a local metadata field, eg.
444 pz:limitmap:somefield[t]=local:otherfield
448 For search, when limit and or filtering is in place and search
449 is identical to previous search, the result set is re-used and the
450 target is not searched.
452 Limits may work perform local filtering as well, by using "local:"
457 Updated bytarget command to contain a suggestions element with misspelled
458 words and suggestions to these. pz2.js has been updated to deliver this
459 onwards as well. Only target that currently delivers this is the solr
460 client in YAZ 4.2.18.
464 New service definition element, xslt, that allows an embedded stylesheet
465 to be defined. This can be referred to from pz:xslt as an alternative to
468 New pz:sortmap:field setting for specifying hints on how to make
469 a target natively sort on a field. This is used for command=show in
470 conjunction with sort.
472 New pz:url setting for specifying the actual URL for a target. When
473 this is used the target ID is not used as URL anymore and the target ID
474 may be almost any string (not including []).
476 command=termlist without name parameter returns all termlists/facets.
477 Previously if name parameter was omitted, only "subject" was returned.
481 Make termlist sorting stable. Terms with same frequency are now sorted by
482 their display name. This makes a pretty display and improves our
483 regression test because qsort is not a stable sort.
485 New sort parameter value 'position'. The 'position' sorts merged records
486 by their original position from the remote target. This is primarily useful
487 for debugging and may be used for targets that already perform some kind
488 of relevance ranking. Note that sort by default is decreasing; so to get
489 records in their original order sort=position:1 must be used.
493 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
495 Facility to change working directory for pazpar2 daemon. Option -wdir
496 sets working directory to dir. This facility is useful if core dumps
497 must be saved. In this case, the current working directory must be
498 writable by the running user, such as "nobody".
502 New configuration element <icu_chain> for <server>/<service> which
503 allows a named ICU rule (chain) to be defined. The names relevance,
504 sort, mergekey and facet are used for those operations. The definition
505 <icu_chain id="sort" locale="en"> .. </icu_chain>
507 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
508 And so on.. for relevance, mergekey and facet as well. The latter
509 style is deprecated. The facet terms are normalized by the facet
510 rule by default. This may be changed on a metadata field basis by
511 defining the new attribute 'facetrule' for the metadata element.
513 <icu_chain id="myrule" locale="en"> ... </icu_chain>
514 <metadata name="author" termlist="yes" facetrule="myrule"/>
516 Preserve rorder for merged metadata. Fixes issue as reported by Sven
517 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
519 tmarc.xsl: set journal-subpart to 773$ only.
523 Modify the behavior for the limit parameter (first defined in 1.5.7).
524 Mapping of limit searches are now defined by the new configuration item
525 pz:limitmap. Fix a dead-lock problem with the limit parameter.
527 Extend tmarc.xsl to extract 773$g data (OpenURL).
531 ICU default maps remove backquote (`).
533 Command 'search' takes limit parameter (optional). The limit parameter
534 allows a search to be limited one or more facets and the corresponding
535 values. This is for server side filtering.
537 Configure tweak: Use -lm for log(3) if needed
541 Fix a problem with skiparticle sortkey that could be completely
542 ignored (and reduced to "").
544 Fix dependency problem in pazpar2 RPM package (did not require
545 libyaz4 as it should).
549 Fix memory leak that occurred for command=termlist&name=xtargets .
551 Pazpar2 may save HTTP requests. Enabled by option -R.
555 Experimental support for DTIC DADS target. New dads-pz2.xsl.
557 Support for query_syntax (overrides the default for SRU | Z39.50)
559 Support for extraArgs (ZOOM "extraArgs" option) for targets
561 New commands: status-server and status-session
565 Fix for threaded runs: Client now have a copy of the database URL,
566 which can used after the database has been release from the client.
567 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
569 tmarc.xsl: Add journal-title-abbrev and full text.
571 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
573 Fix for cmd=record before search.
575 Session Logging clean up.
577 Fix wrong termlist factor when maxrecs is different from 100.
581 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
582 Term factor is default enabled but can be diseabled by
583 pz:termlist_term_factor=0
587 Add scaling of facet count. Currently always enabled, needs fixing.
588 Allow user-defined info for target suffix. This has no meaning in
589 Pazpar2 except to distinguish targets from each other. The suffix
590 data begins with #. For example z3950.indexdata.com/gils#Mydata
592 Added exact-match recordfilter; format name=value
596 SOLR support. Pazpar2 may operate as web service client for SOLR.
600 Fix for show command and block=1 (dead lock). Bug was introduced in
605 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
606 tested on CentOS 5.5 only.
610 Fix problem with result sets being removed from a client session
611 if the connection for it was resused by another session. Bug #3489.
613 New iphone UI for Pazpar2 (www/iphone).
617 Fixes for threaded operation.
619 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
621 New example services in etc/services in source. In the Debian packages
622 these are located in /etc/pazpar2/services-available
624 Threaded mode operational on Windows. Requires Windows 7 or Windows
627 Default value of setting pz:max_connections is 0 which means that there
628 is no limit on number of connections.
632 Pazpar2 may operate in threaded mode. Enabled by element threads in
633 the configuration. See pazpar2_conf for details.
635 New setting setting: pz:max_connections. Setting pz:max_connections is
636 a limit of number of sockets to a host. When this limit is reached,
637 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
638 The client will be marked Client_Error when it can not be searched
639 (other clients in a session may work). If pz:max_connections is not set
640 for a target, a value of 30 will be used. Note: the pz:max_connections
641 will only work in threaded mode.
643 pz2.js: JSON support for show.
645 Debian package: Enable default service, default.xml, before starting
646 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
650 Debian version depends on on libyaz4. Note that Pazpar2 will still
651 compile from source with YAZ 3.
653 Split services into separate files. The example configuration file
654 pazpar2.cfg.dist now includes a default service default.xml (part of
655 etc). And default.xml includes settings/edu.xml. The default.xml file,
656 not to be confused with settings/defaults.xml, is a template for jsdemo
657 and other services. The Debian package installs /etc/pazpar2/server.xml
658 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
659 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
660 The default.xml (from etc) is installed in /etc/pazpar2/services-available
661 and a symlink to it is created from services-enabled. The default.xml
662 service is unnamed and, thus, will be used by jsdemo and test1.
664 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
665 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
669 Support for additional fields in cf.xsl and pazpar2.conf.dist:
670 publisher, available, due, location (=locallocation), callno
671 (=callnumber), thumburl and score.
673 Describe pz:xslt and the auto setting.
675 Move mergekey definition away from the normalization stylesheets and
676 define a mergekey common for all target types in pazpar2.cfg.
678 Code update: Use the Odr_int type for hit counts. This is part of
679 YAZ 3.0.47 and later and so configure checks for that.
683 Metadata attribute 'skiparticle' also works for ICU based
684 normalization. (was only working for the non-ICU/ASCII before).
686 Command bytarget with argument settings=1 will show settings per
687 target.. This is to be able to verify correct settings and be able to
688 test that they are correct. The database settings array size is now
689 also stored.. Problems with database settings array is that if not
690 careful it will be too small (smaller than dictionary per-service
693 Make record list sorting stable by comparing mergekey for records if
694 relevance/title or other sorting criteria all match. This is merely to
695 ensure that our regressions tests works (reproducible output).
697 Relevance calculation changes: use a different denominator (length) for
698 per-field relevance scoring.. Instead of length of all ranked fields we
699 now use length of individual fields (as if they were individual "free"
700 text fields). This will ensure that documents with a long field with no
701 match (say description) will not "hurt" a title match.
703 Diagnostic member was not set on connection error. Fixed
707 Command search takes two optional parameters, startecs and maxrecs,
708 that specifies the start offset (0, 1, ...) and maximum number of records
709 to fetch for each target.
711 XSLTs + MARC maps are cached within a session so we don't re-parse
712 them over and over again. Even for a session with a single search
713 there's much to be gained because many targets use the same
716 The metadata attribute 'mergekey' now takes one of three values 'no',
717 'required', 'optional' . And the resulting mergekey from metadata
718 is now ordered in the same way as metadata in the service definition.
719 Older Pazpar2 version use the order in which metadata appeared in a
722 The search argument 'filter' now offers a new operator ~ which does a
723 substring match. The = operator works as before: string match for
724 anything but pz:id, or target match for pz:id.
726 New setting pz:recordfilter. The value of this setting takes the
727 form name[~value]. This setting makes Pazpar2 ignore all retrieved
728 records that do not have the metadata element name with value substring
731 Pazpar2 allows YAZ log level to be set (option -v).
735 For WS responses Pazpar2 creates XML header. Exception: raw record.
737 Setting XML files are now stored in etc/settings instead of etc. This
738 reflects the layout with the Debian package layout.
740 Settings may be posted for command=settings. The POSTed settings must
741 have root element 'settings' like regular setting files. In order to be
742 recognized, the POST request must use Content-Type=text/xml.
744 A service may be posted for command=init. This service will be used
745 during the session. The service may have its own target settings,
746 ICU config, timeout, etc. In order to be recognized, the POST request
747 must use Content-Type=text/xml.
749 Timeout values may be given per-service. That's element 'timeout'
750 which takes three attribute values (a subset may be given): 'session',
751 'z3950_operation', 'z3950_session'. Option -T is no longer supported
752 - used to specify session timeout.
754 Option -t tests the Pazpar2 configuration and returns exit code
755 (0=success, non-zero=failure). In previous version of Pazpar2, -t
756 specified local settings.
758 In version 1.2.0 the configuration file - after include processing -
759 was dumped to stdout. Now, the configuration is only dumped to the
760 yaz log file if option -d is given.
764 Configuration may now have multiple server areas. This means that a
765 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
766 yet supported - on a server basis. Configuration may also have multiple
767 services .. That is repeating service elements inside a server. Each
768 has an attribute 'id' which serves as service ID. This ID in turn may
769 be used in a Pazpar2 session, by specifying parameter service=ID for
770 command init. There can be at most one unnamed service inside a server
771 which can be referred to by not specifying an service ID for command
772 init (backwards compatible). In order to partition multiple servers and
773 services a new include directive has been added. This takes an attribute
774 'src' which specifies one or more sub-files. For example to include
775 service files, one might use:
776 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
777 It is the intention that that completely makes the settings directive
780 Fix problem where the record command would wait forever if there were
781 no targets to wait for (activeclients == 0).
785 One result set is created per session (last search) rather than for
786 each connection which happen to be shared (bug #3009).
788 marc21 stylesheets changed for efficiency.
792 Session timeout may be specified on the command-line as option -T.
794 Pazpar2 may now be operated in a no-merged mode for records.. All records
795 will be considered unique. This mode is enabled if no mergekey is
796 generated by the normalization stylesheet (pz:xslt).
798 Pazpar2 caches original records from each target and the 'record' command
799 with offset returns the original record if 'syntax' and 'esn' are NOT
800 specified. This speeds up retrieval of original records but also means
801 that Pazpar2 uses more memory. The cached records will be freed when the
802 session terminates or a new search is executed.
804 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
805 library part of YAZ is used.
807 Added SRU client support.
809 Automatically computes pz:nativesyntax if not provided. Works for XML and
812 --- 1.0.13 2008/11/24
814 Command bytarget returns name of target (if defined).
816 --- 1.0.12 2008/11/04
818 Fixed bug #2021.. location now holds all brief elements.
820 --- 1.0.11 2008/10/15
822 Fixed check for application/x-www-form-urlencoded parameters.
824 --- 1.0.10 2008/10/14
826 Fixes for IE in pz2.js.
828 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
832 Changed the JS library pz2.js to use POST for long URL (+ params).
834 Added installation instructions for Windows. Note: NT services is
835 NOT available until we make a new release of YAZ.
837 Preserve order of repeated metadata fields (they were reversed before).
839 More MARC21 information extracted for metadata.
843 Fixed bug #1162: HTML entities are not escaped properly.
845 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
849 Marc21 stylesheet updated to reflect multiple full text fields
853 Fixed bug in pz2.js WRT DOMElement attributes on IE.
855 Fixed bug 2100: Database wildcards not working
859 Added support for retrieval of records in binary.
861 Fixed bug 1794: Pazpar2 does not return valid XML.
863 Deal with ICU not returning sortkey (resulted in SEGV before).
867 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
868 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
870 Improved diagnostics when Pazpar2 HTTP decoding fails.
872 Pazpar2 requests may be POSTed as using Content-Type
873 application/x-www-form-urlencoded.
875 Pazpar2 honors LF in HTTP headers.
877 Handle targets that handle negative hit counts (should not happen, but it
882 ICU is used for tokenization and normalization of the following: mergekey,
883 sorting, relevance terms.
885 Debian package now enables ICU tokenization and normalization by default.
889 Exposed user setting values (i.e. non-pz: names) to the record systems in two
890 ways: Either as parameters to the normalization stylesheets (which would allow the
891 programmer to postprocess or use the values in any way) or after the normalization
892 step, in which case values are made part of the normalized record (and available for
893 sorting, termlists, display, or other interface-related use.
895 Implemented sorting by year.
897 Option -d dumps records to the current log file instead of stderr.
899 Fixes for compilation on cygwin.
901 Z39.50 client code uses pz:elements. pz:elements was recognized in
902 earlier Pazpar2 versions but it was not used for anything.
904 icu_chain_test is using fgets instead of getline - fixes compilation
907 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
908 query conversions fail (rather than _any_). This means targets that do
909 not support some fields are ignored in a search.
913 Improved handling of socket timeout for Z39.50 connections.
915 Misc documentation updates and spell fixes.
917 Debian package pazpar2 creates log rotate entry.
919 Debian package pazpar2-apache2 reloads Apache2.
921 jsdemo included in distribution. It illustrates the use of the js/pz2.js
926 First public release.
