3 Fix PAZ-1009: Do not create local facets when using facetmap:split
7 Facet ID term map PAZ-1008
8 New setting pz:facetmap:split:name (refer to documentation)
12 Sort by retrieval PAZ-1006
13 Allows sorting by order that records were retrieved from databases.
15 Response from bytarget command includes native query PAZ-1005
17 Use lx2.loc.gov:210/LCDB_MARC8 instd of z3950.loc.gov:7090/voyager PAZ-1003
21 New metadata facility "icurule" for normalizing metadata text PAZ-1002
22 This allows ICU normalization of text before in-cluster merging takes

27 Fix test_limit_limitmap fails PAZ-1000
31 Limitmap ccl: deal with quotes and backslash PAZ-999
33 Handle date range from a limit parameter PAZ-997
34 The CCL term is not quoted unless it includes blanks. This will ensure
35 that r=r is handled correctly. This changes behavior a bit. If term
36 should not be converted to @and, then instead of r=r one should use

49 Update and fix documentation for preferred targets
51 Fix spelling of present_chunk in documentation
55 Increase facet limit PAZ-990
56 No longer a limit on facets.
58 Pazpar2-js no longer requires Apache2 PAZ-989
59 Package pazpar2-apache2 sets up everything WRT apache and only
60 package which requires it. pazpar2-apache depends on pazpar2-js.
64 Larger string buffer for forward address PAZ-987
65 Fixes buffer overflow that could occur if forward address is IPV6.
67 Updates to Windows NMAKE makefile for Visual Studio 2013.
71 Use YAZ backtrace facility PAZ-983. In case of crashes YAZ log may
72 include more details about the fault. Better install gdb and the
73 debug version of pazpar2 (pazpar2-dbg on Debian/Ubuntu).
75 Per target timeout PAZ-981
76 New setting pz:timeout which overrides z3950_operation timeout
81 Re-introduce journal-subpart PAZ-980
82 Both citation and journal-subpart have same value.
86 Add Ubuntu utopic 14.04 and Ubuntu saucy 13.10 to the list of packages
89 Remove from js/pz2.js the code that translates just two diagnostic
90 codes (1 and 2) into human-readable messages. This is no longer
91 necessary at all, as PazPar2 has been returning the message as well as
92 the code in its responses since December 2012. Fixes PAZ-978.
94 primo xsl produces citation rather than journal-subpart PAZ-972
95 (fix in 1.8.1 was incorrect)
97 Fix missing .url files PAZ-977
98 Add missing .url+.cfg and add proper check for it.
102 Turbomarc needs number check for date 903 map PAZ-973
104 primo-pz2.xsl creates citation rather than journal-subpart PAZ-972
106 pz2.js: on successful search, issue a "show" command only if a show
107 callback function has been installed. Fixes part of PAZ-975
111 New command=stop which stops further search&retrieval for active
114 CF/primo XSL generates {volume,issue,pages}-number that are defined
115 in default Pazpar2 service definition. PAZ-968 PAZ-970
119 Various fixes for threaded operation PAZ-960 thru PAZ-966
121 Dump main configuration file during start of Pazpar2 PAZ-957
125 Log ingest failures and record failures:
127 Clean up logging PAZ-942
128 Use session lead in more places. Log hits/records/filtered for each
129 target when fetching is complete. Log hit count when a search
130 (response) is received. Remove some less useful log messages.
132 Fix warning about about missing (internal) stylesheet PAZ-956
134 Report number of filtered records in bytarget PAZ-954
136 Cache XML documents as they appear after normalization. The key
137 for the cache is database+record offset. Cache is removed if query
138 is modified for search. This speeds up re-establishing a result set
139 for databases where new query is same previous query.
143 poll: add assert for number of FDs; abort on poll failure
147 Fix hang for 2nd use of target with unresolved DNS PAZ-949
151 Use poll rather than select for main event loop to overcome limit of

194 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
195 this code is only executed once.
197 Fix typos is sortmap documentation.
199 Doc: fix misplaced variablelist tag.
201 --- 1.6.39 2014/02/19
203 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
204 It's been like that since version 1.1.1 from August 2009.
206 Add support for result-set caching via memcached. See description of
207 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
209 Add support for a <metadata> container tag. Patfh from Sven Porst.
211 Add support for XInclude in main configuarion file. Patch from Sven Porst.
213 Add client_{lock,unlock} before call to non_block_events in
214 connection_continue. Problem is that if non_block_events fire records,
215 then we will not unlock client at all. And as a result, a dead-lock

220 Avoid removing slash and other characters for generic metadata that
221 looks like a URL (contains ://). PAZ-915
223 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
225 Cluster merge fixes. PAZ-901

238 Preserve order of records within cluster PAZ-902
240 testing: use yaz-ztest -V if possible and use YAZ in sibling directory
243 Allow clustered records to be ingested during retrieval. PAZ-900
245 Fix void function error which cannot return a value.

255 Better error message for CCL parse errors PAZ-887
257 --- 1.6.35 2013/09/23
259 New target setting: pz:authentication_mode. PAZ-896
261 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
263 Strip #-suffix for ZOOM URLs. PAZ-892
265 --- 1.6.34 2013/08/30
267 Fix issue with hanging show/bytarget. Could happen if new search was
268 fired with filter before show from previous show completed.
270 Add 'date' handling for solr-pz2.xsl.
272 --- 1.6.33 2013/08/13
274 pz:authentication may carry user group password. If pz:authentication
275 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
276 authentication. Two forms are allowed
279 If no blanks are present, open authentication is in use (as before).
281 Fix {prev,next}recid elements that are returned by record
282 command. These were incorrect in versions 1.6.23 thru 1.6.32.
284 --- 1.6.32 2013/06/14
286 Experimental support for snippets. If argument snippets=1 is given
287 for command record or show, the text will include <match>-tags for
288 those area that matches.
290 Fix memory leak WRT client structures (incorrect inc ref count).
292 Log when a HTTP response is serialized and the time elapsed.
294 New command, service, which returns current service XML in use for
297 --- 1.6.31 2013/05/24
299 Local limit for fields of type "generic" (ie text fields) are
300 now normalized by mergekey rule before comparison takes place.
301 Before, no normalization took place and comparsion was, thus, exact.
303 New facility: dynamic rank , which allows ranking to be changed
304 for an existing result set. The rank can be set for search or
305 show. This overrides the rank for metadata elements (which fields
308 New facility:dynamic mergekey , which allows mergekey to be changed
309 for an existing result set. The mergekey can be set for search or
312 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
313 Also, allow ports to be given as names (not just integers).
314 Fix @-notation on systems that don't support IPV6 sockets.
316 --- 1.6.30 2013/04/26
318 Add MasterKey Connect configuration. Refer to section "non-standard
319 databases" for more information.
321 Allow timeformat for log to be specified with option -m (as Metaproxy
324 New Debian package pazpar2-dbg.
326 Fix NULL ptr reference of se->relevance. If a new search is initiated
327 and a CCL query fails to parse, Pazpar2 could crash.
329 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
330 existed in 1.6.29 only.
332 --- 1.6.29 2013/04/05
334 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
335 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
336 changed by setting "host" attribute for the "listen" element.
338 Change semantics of pz:extendrecs. Allow for repeated fetches .
339 pz:extendrecs is now the number of extra records to fetch (was total
342 --- 1.6.28 2013/03/21
344 Fix hang or memory violation if show occurred before a search. (not that
345 it makes much sense to perform a show before a search).
347 --- 1.6.27 2013/03/08
349 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
352 --- 1.6.26 2013/03/08
354 New pz:metadata attribute, empty="empty-value" for Pazpar2's
355 internal representation. With this attribute, Pazpar2 treates an empty
356 pz:metadata type as having the value for "empty" - if empty.
358 New setting, pz:extendrecs, which triggers extended fetch of records
359 for a database beyond pz:maxrecs for a show command.
361 Fix warning that was falsely issued for "missing limitmap".
363 Log message for Pazpart start/stop changed. Now using same style as
364 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
366 --- 1.6.25 2013/02/07
368 Fix hang of 2nd command=show with esn/syntax given.
370 --- 1.6.24 2013/01/18
372 New merge attribute type: 'first', which takes all metadata fields
373 from first target that returns the particular field.
375 --- 1.6.23 2013/01/02
377 Extend info command with hostname and YAZ SHA1
378 Indent results for both command stat and info.
380 Allow limit on merged content. The new configuration metadata
381 element, limitcluster, configures that a metadata element (name) be used
382 as limit name for search. Applies to the whole service (ie all targets),
383 unlike pz:limitmap which is configured per-target (database).
385 New feature: limitmap local:* matches against all metadata fields.
387 Allow repeated list in limitmap spec . Separated by comma. For
388 example: value="local:title,rpn:@attr 1=4".
390 New element <message> in bytarget response. Holds diagnostic message
391 of code (say 'Unsupported Use Attribute' for Bib-1 114).
393 Improved logging for record ingestion failures.
395 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
396 when YAZ is compiled without ICU support.
398 --- 1.6.22 2012/10/11
400 Requires YAZ-4.2.40 to support native solr support.
402 Fix and improve logic handling whether or not to re-do search on sort
403 order changes. A sort order with change in ascending/descending only
404 whould not trigger a new search, which is required for targets with
405 native sorting capabilities. Each client is now checked if instructions
406 (sortmap) exist for native sorting and only client that does requires
407 it is researched. Other clients is just re-ingesting the records,
408 they already have. The resultset is now cleared if any researching
411 Connection sharing between session has broken since version 1.6.8 with
412 introduction of logic that would minimize searching if pazpar2 could
413 detect this based on same query and limits and partly sort order.
414 This could lead to segementations violations.
416 Added a chapter in the manaul about relevance ranking.
418 --- 1.6.21 2012/09/24
420 Rank tweak: follow=number will increase mult by number if two terms
421 occur next to each other; number-1 if they are one term apart , .. 0
422 if they are number a part (all in order). Default is 0 (following
423 terms has no effect).
425 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
426 value given by lead and l is length from beginning of field where
427 term occurs (l=0 for first term, l=1 for second term, ..). Default
430 Rank tweak: length=strategy. length="linear" if mult is to be divided
431 by length (existing, default behavior), length="log" if mult is to be
432 divided by log2(1+length), length="none" if mult is not to be affected
435 --- 1.6.20 2012/09/21
437 Rank algorithm details may be printed as part of show response in
438 element <relevance_info>.. This is only printed if <rank debug="yes"/>
441 Record as returned by show/record command have a minimal indentation
442 which makes things human-readable.
444 New configuration of default sorting criteria (sort-default) in
445 service definition. If no criteria is defined it will be as before
448 Search command now supports sort parameter just as the show command.
449 If no parameter is give, it will use the service sort-default value.
451 --- 1.6.19 2012/09/18
453 Rank algorithm skips strings that gets normalized to empty string.
454 For example, & and ! could map to the empty string. The weight for
455 those terms is now 0 (as if they were not part of the query).
457 Rank algorithm does not use CCL from limitmap; only from the query
458 parameter (user query).
462 --- 1.6.18 2012/09/17
464 Rank algorithm configurable by 'rank' element inside service. So far
465 only, attribute 'cluster' is recognized. If cluster="yes", multiple
466 records inside a cluster boosts higher than single records. This
467 is default behavior and existing behavior. cluster="no" takes the
468 average score of each record in a cluster.
470 --- 1.6.17 2012/09/05
472 Fix bad re-use of connections (connections with changing proxy should not
475 --- 1.6.16 2012/08/22
477 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
478 resultset and sorting when the sort order is position. However this will be done on
479 every client poll, which will make pazpar2 continuing reset and fetching.
480 It should only be done on FIRST request where the sort order change.
482 Fix an issue on suggestion option: Also disable suggestions on empty string.
484 Clean up in turbo marc stylesheet.
486 Remove the hardcoded size of termlists.
488 --- 1.6.15 2012/06/27
490 New facility: ccldirective may be given in service definition. Allows
491 CCL parsing to be customized a bit, such as defining names of operators
494 New facility: raw record by checksum, rather than offset. The record
495 command optionally takes checksum which identifies certain record from
498 New facility: per field ranking. Rank may be given as M [F N] where
499 M is default rank and N is rank for CCL terms from field F.
501 --- 1.6.14 2012/06/04
503 Fix for IE7/8 in pz.js
505 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
507 Lower log level some places.
509 Remove some invalid test results.
511 --- 1.6.13 2012/05/23
513 Introducing a version=2 parameter for show, termlist and bytarget commands.
514 This enables pazpar2 to return approximation on hit and count count when
515 doing record filtering using the limit parameter on search and a
516 limitmap with a value of "local:"
518 Setting pz:xslt may embed local XSLT as an alternative to referring
520 Value is not CDATA but XML nodes embedded, so escaping is not necessary
521 but a root element *must* be present. For example:
522 <settings target="target="z3950.indexdata.com/marc">
531 Metadata field rank may given by XML internal document (pz:xslt
532 result). If rank is not given, the rank from service description is
535 Metadata field can now configured a default limitmap and facetmap.
536 Setting limitmap to "local:" would work for all kind of targets, but would
537 prob. not be the optimal solution. But at least better than the default behavior
538 of pazpar2 where no filtering is done.
540 A service definition can now also contains <set/> that defines service-wide
541 settings. These will override server-wide sets and will be overridded by
544 New setting, pz:present_chunk, that specifies number of records to fetch
545 at a time. Zero will disable chunkation; will fetch max_records at once.
547 --- 1.6.12 2012/03/14
549 Revert the format change in termlist response, that could break
550 some clients / UIs since they were expecting an (empty) element
551 if no facet values was found.
553 --- 1.6.11 2012/03/07
555 Revert the behavior of returning errors when unable to block
556 on termlist, bytarget and search, when unable to block due to
557 other block. The client will now receive a regular response,
558 but it will be logged in the server. A parameter (report) is
559 added to change behavior to return error response or WARNING
560 status message. Consider this "API" as private, as it is mostly
561 untested and could be changed in future releases.
563 Fix spell error in pz2.js fix in 1.6.10.
565 New Marc2TurboMarc.xsl (contribution from Sven Porst).
566 Can solve the missing marc21.xsl updates in some cases.
568 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
569 substring (contribtion from Sven Porst)
571 marc21.xsl: fix 1-based substring call
573 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
575 Add test_termlist_block to test suite
577 --- 1.6.10 2012/02/23
579 Fix SEGV for invalid PQFs and SRU/SOLR targets
580 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
582 Fix pz2.js: "null object" due to change in in bytarget result XML.
584 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
585 Added this normalization to the other subject-long fields (d6xx),
586 where it was missing.
588 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
589 Still differences around medium and holdings. marc21.xsl is not
590 longer active used by Index Data, and should be considered unsupported.
591 Use tmarc.xsl instead.
595 Fix SEGV that could occur for failed connections.
599 Fix bug for command sort that could return no results for active clients
600 (from previous search). This bug was present in 1.6.6-1.6.7.
602 Fix bug in results that could include results that should have been
603 filtered out. This bug was present in 1.6.6-1.6.7.
607 Fix bug introduced in 1.6.6 where a connection re-use could stall
610 Local filtering may now specify a local metadata field, eg.
611 pz:limitmap:somefield[t]=local:otherfield
615 For search, when limit and or filtering is in place and search
616 is identical to previous search, the result set is re-used and the
617 target is not searched.
619 Limits may work perform local filtering as well, by using "local:"
624 Updated bytarget command to contain a suggestions element with misspelled
625 words and suggestions to these. pz2.js has been updated to deliver this
626 onwards as well. Only target that currently delivers this is the solr
627 client in YAZ 4.2.18.
631 New service definition element, xslt, that allows an embedded stylesheet
632 to be defined. This can be referred to from pz:xslt as an alternative to
635 New pz:sortmap:field setting for specifying hints on how to make
636 a target natively sort on a field. This is used for command=show in
637 conjunction with sort.
639 New pz:url setting for specifying the actual URL for a target. When
640 this is used the target ID is not used as URL anymore and the target ID
641 may be almost any string (not including []).
643 command=termlist without name parameter returns all termlists/facets.
644 Previously if name parameter was omitted, only "subject" was returned.
648 Make termlist sorting stable. Terms with same frequency are now sorted by
649 their display name. This makes a pretty display and improves our
650 regression test because qsort is not a stable sort.
652 New sort parameter value 'position'. The 'position' sorts merged records
653 by their original position from the remote target. This is primarily useful
654 for debugging and may be used for targets that already perform some kind
655 of relevance ranking. Note that sort by default is decreasing; so to get
656 records in their original order sort=position:1 must be used.
660 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
662 Facility to change working directory for pazpar2 daemon. Option -wdir
663 sets working directory to dir. This facility is useful if core dumps
664 must be saved. In this case, the current working directory must be
665 writable by the running user, such as "nobody".
669 New configuration element <icu_chain> for <server>/<service> which
670 allows a named ICU rule (chain) to be defined. The names relevance,
671 sort, mergekey and facet are used for those operations. The definition
672 <icu_chain id="sort" locale="en"> .. </icu_chain>
674 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
675 And so on.. for relevance, mergekey and facet as well. The latter
676 style is deprecated. The facet terms are normalized by the facet
677 rule by default. This may be changed on a metadata field basis by
678 defining the new attribute 'facetrule' for the metadata element.
680 <icu_chain id="myrule" locale="en"> ... </icu_chain>
681 <metadata name="author" termlist="yes" facetrule="myrule"/>
683 Preserve rorder for merged metadata. Fixes issue as reported by Sven
684 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
686 tmarc.xsl: set journal-subpart to 773$ only.
690 Modify the behavior for the limit parameter (first defined in 1.5.7).
691 Mapping of limit searches are now defined by the new configuration item
692 pz:limitmap. Fix a dead-lock problem with the limit parameter.
694 Extend tmarc.xsl to extract 773$g data (OpenURL).
698 ICU default maps remove backquote (`).
700 Command 'search' takes limit parameter (optional). The limit parameter
701 allows a search to be limited one or more facets and the corresponding
702 values. This is for server side filtering.
704 Configure tweak: Use -lm for log(3) if needed
708 Fix a problem with skiparticle sortkey that could be completely
709 ignored (and reduced to "").
711 Fix dependency problem in pazpar2 RPM package (did not require
712 libyaz4 as it should).
716 Fix memory leak that occurred for command=termlist&name=xtargets .
718 Pazpar2 may save HTTP requests. Enabled by option -R.
722 Experimental support for DTIC DADS target. New dads-pz2.xsl.
724 Support for query_syntax (overrides the default for SRU | Z39.50)
726 Support for extraArgs (ZOOM "extraArgs" option) for targets
728 New commands: status-server and status-session
732 Fix for threaded runs: Client now have a copy of the database URL,
733 which can used after the database has been release from the client.
734 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
736 tmarc.xsl: Add journal-title-abbrev and full text.
738 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
740 Fix for cmd=record before search.
742 Session Logging clean up.
744 Fix wrong termlist factor when maxrecs is different from 100.
748 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
749 Term factor is default enabled but can be diseabled by
750 pz:termlist_term_factor=0
754 Add scaling of facet count. Currently always enabled, needs fixing.
755 Allow user-defined info for target suffix. This has no meaning in
756 Pazpar2 except to distinguish targets from each other. The suffix
757 data begins with #. For example z3950.indexdata.com/gils#Mydata
759 Added exact-match recordfilter; format name=value
763 SOLR support. Pazpar2 may operate as web service client for SOLR.
767 Fix for show command and block=1 (dead lock). Bug was introduced in
772 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
773 tested on CentOS 5.5 only.
777 Fix problem with result sets being removed from a client session
778 if the connection for it was resused by another session. Bug #3489.
780 New iphone UI for Pazpar2 (www/iphone).
784 Fixes for threaded operation.
786 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
788 New example services in etc/services in source. In the Debian packages
789 these are located in /etc/pazpar2/services-available
791 Threaded mode operational on Windows. Requires Windows 7 or Windows
794 Default value of setting pz:max_connections is 0 which means that there
795 is no limit on number of connections.
799 Pazpar2 may operate in threaded mode. Enabled by element threads in
800 the configuration. See pazpar2_conf for details.
802 New setting setting: pz:max_connections. Setting pz:max_connections is
803 a limit of number of sockets to a host. When this limit is reached,
804 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
805 The client will be marked Client_Error when it can not be searched
806 (other clients in a session may work). If pz:max_connections is not set
807 for a target, a value of 30 will be used. Note: the pz:max_connections
808 will only work in threaded mode.
810 pz2.js: JSON support for show.
812 Debian package: Enable default service, default.xml, before starting
813 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
817 Debian version depends on on libyaz4. Note that Pazpar2 will still
818 compile from source with YAZ 3.
820 Split services into separate files. The example configuration file
821 pazpar2.cfg.dist now includes a default service default.xml (part of
822 etc). And default.xml includes settings/edu.xml. The default.xml file,
823 not to be confused with settings/defaults.xml, is a template for jsdemo
824 and other services. The Debian package installs /etc/pazpar2/server.xml
825 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
826 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
827 The default.xml (from etc) is installed in /etc/pazpar2/services-available
828 and a symlink to it is created from services-enabled. The default.xml
829 service is unnamed and, thus, will be used by jsdemo and test1.
831 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
832 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
836 Support for additional fields in cf.xsl and pazpar2.conf.dist:
837 publisher, available, due, location (=locallocation), callno
838 (=callnumber), thumburl and score.
840 Describe pz:xslt and the auto setting.
842 Move mergekey definition away from the normalization stylesheets and
843 define a mergekey common for all target types in pazpar2.cfg.
845 Code update: Use the Odr_int type for hit counts. This is part of
846 YAZ 3.0.47 and later and so configure checks for that.
850 Metadata attribute 'skiparticle' also works for ICU based
851 normalization. (was only working for the non-ICU/ASCII before).
853 Command bytarget with argument settings=1 will show settings per
854 target.. This is to be able to verify correct settings and be able to
855 test that they are correct. The database settings array size is now
856 also stored.. Problems with database settings array is that if not
857 careful it will be too small (smaller than dictionary per-service
860 Make record list sorting stable by comparing mergekey for records if
861 relevance/title or other sorting criteria all match. This is merely to
862 ensure that our regressions tests works (reproducible output).
864 Relevance calculation changes: use a different denominator (length) for
865 per-field relevance scoring.. Instead of length of all ranked fields we
866 now use length of individual fields (as if they were individual "free"
867 text fields). This will ensure that documents with a long field with no
868 match (say description) will not "hurt" a title match.
870 Diagnostic member was not set on connection error. Fixed
874 Command search takes two optional parameters, startecs and maxrecs,
875 that specifies the start offset (0, 1, ...) and maximum number of records
876 to fetch for each target.
878 XSLTs + MARC maps are cached within a session so we don't re-parse
879 them over and over again. Even for a session with a single search
880 there's much to be gained because many targets use the same
883 The metadata attribute 'mergekey' now takes one of three values 'no',
884 'required', 'optional' . And the resulting mergekey from metadata
885 is now ordered in the same way as metadata in the service definition.
886 Older Pazpar2 version use the order in which metadata appeared in a
889 The search argument 'filter' now offers a new operator ~ which does a
890 substring match. The = operator works as before: string match for
891 anything but pz:id, or target match for pz:id.
893 New setting pz:recordfilter. The value of this setting takes the
894 form name[~value]. This setting makes Pazpar2 ignore all retrieved
895 records that do not have the metadata element name with value substring
898 Pazpar2 allows YAZ log level to be set (option -v).
902 For WS responses Pazpar2 creates XML header. Exception: raw record.
904 Setting XML files are now stored in etc/settings instead of etc. This
905 reflects the layout with the Debian package layout.
907 Settings may be posted for command=settings. The POSTed settings must
908 have root element 'settings' like regular setting files. In order to be
909 recognized, the POST request must use Content-Type=text/xml.
911 A service may be posted for command=init. This service will be used
912 during the session. The service may have its own target settings,
913 ICU config, timeout, etc. In order to be recognized, the POST request
914 must use Content-Type=text/xml.
916 Timeout values may be given per-service. That's element 'timeout'
917 which takes three attribute values (a subset may be given): 'session',
918 'z3950_operation', 'z3950_session'. Option -T is no longer supported
919 - used to specify session timeout.
921 Option -t tests the Pazpar2 configuration and returns exit code
922 (0=success, non-zero=failure). In previous version of Pazpar2, -t
923 specified local settings.
925 In version 1.2.0 the configuration file - after include processing -
926 was dumped to stdout. Now, the configuration is only dumped to the
927 yaz log file if option -d is given.
931 Configuration may now have multiple server areas. This means that a
932 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
933 yet supported - on a server basis. Configuration may also have multiple
934 services .. That is repeating service elements inside a server. Each
935 has an attribute 'id' which serves as service ID. This ID in turn may
936 be used in a Pazpar2 session, by specifying parameter service=ID for
937 command init. There can be at most one unnamed service inside a server
938 which can be referred to by not specifying an service ID for command
939 init (backwards compatible). In order to partition multiple servers and
940 services a new include directive has been added. This takes an attribute
941 'src' which specifies one or more sub-files. For example to include
942 service files, one might use:
943 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
944 It is the intention that that completely makes the settings directive
947 Fix problem where the record command would wait forever if there were
948 no targets to wait for (activeclients == 0).
952 One result set is created per session (last search) rather than for
953 each connection which happen to be shared (bug #3009).
955 marc21 stylesheets changed for efficiency.
959 Session timeout may be specified on the command-line as option -T.
961 Pazpar2 may now be operated in a no-merged mode for records.. All records
962 will be considered unique. This mode is enabled if no mergekey is
963 generated by the normalization stylesheet (pz:xslt).
965 Pazpar2 caches original records from each target and the 'record' command
966 with offset returns the original record if 'syntax' and 'esn' are NOT
967 specified. This speeds up retrieval of original records but also means
968 that Pazpar2 uses more memory. The cached records will be freed when the
969 session terminates or a new search is executed.
971 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
972 library part of YAZ is used.
974 Added SRU client support.
976 Automatically computes pz:nativesyntax if not provided. Works for XML and
979 --- 1.0.13 2008/11/24

1001 Added installation instructions for Windows. Note: NT services is
1002 NOT available until we make a new release of YAZ.
1004 Preserve order of repeated metadata fields (they were reversed before).
1006 More MARC21 information extracted for metadata.

1018 --- 1.0.6 2008/03/12
1020 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1022 Fixed bug 2100: Database wildcards not working
1024 --- 1.0.5 2007/11/09
1026 Added support for retrieval of records in binary.
1028 Fixed bug 1794: Pazpar2 does not return valid XML.
1030 Deal with ICU not returning sortkey (resulted in SEGV before).
1032 --- 1.0.4 2007/09/28
1034 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1035 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1037 Improved diagnostics when Pazpar2 HTTP decoding fails.
1039 Pazpar2 requests may be POSTed as using Content-Type
1040 application/x-www-form-urlencoded.
1042 Pazpar2 honors LF in HTTP headers.
1044 Handle targets that handle negative hit counts (should not happen, but it
1047 --- 1.0.3 2007/09/19
1049 ICU is used for tokenization and normalization of the following: mergekey,
1050 sorting, relevance terms.
1052 Debian package now enables ICU tokenization and normalization by default.
1054 --- 1.0.2 2007/08/22
1056 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1057 ways: Either as parameters to the normalization stylesheets (which would allow the
1058 programmer to postprocess or use the values in any way) or after the normalization
1059 step, in which case values are made part of the normalized record (and available for
1060 sorting, termlists, display, or other interface-related use.
1062 Implemented sorting by year.
1064 Option -d dumps records to the current log file instead of stderr.
1066 Fixes for compilation on cygwin.
1068 Z39.50 client code uses pz:elements. pz:elements was recognized in
1069 earlier Pazpar2 versions but it was not used for anything.
1071 icu_chain_test is using fgets instead of getline - fixes compilation
1074 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1075 query conversions fail (rather than _any_). This means targets that do
1076 not support some fields are ignored in a search.
1078 --- 1.0.1 2007/07/03
1080 Improved handling of socket timeout for Z39.50 connections.
1082 Misc documentation updates and spell fixes.
1084 Debian package pazpar2 creates log rotate entry.
1086 Debian package pazpar2-apache2 reloads Apache2.
1088 jsdemo included in distribution. It illustrates the use of the js/pz2.js
