3 fix PAZ-1013 - do not re-search if facetlimit scan fails to find value
7 Fix PAZ-1015, which prevented the docs from being built, and therefore
8 the whole package from being released.
12 Fix PAZ-1009: Do not create local facets when using facetmap:split
16 Facet ID term map PAZ-1008
17 New setting pz:facetmap:split:name (refer to documentation)
21 Sort by retrieval PAZ-1006
22 Allows sorting by order that records were retrieved from databases.
24 Response from bytarget command includes native query PAZ-1005
26 Use lx2.loc.gov:210/LCDB_MARC8 instd of z3950.loc.gov:7090/voyager PAZ-1003
30 New metadata facility "icurule" for normalizing metadata text PAZ-1002
31 This allows ICU normalization of text before in-cluster merging takes
34 Heuristics to deal with Primo s/e/page PAZ-1001
36 Fix test_limit_limitmap fails PAZ-1000
40 Limitmap ccl: deal with quotes and backslash PAZ-999
42 Handle date range from a limit parameter PAZ-997
43 The CCL term is not quoted unless it includes blanks. This will ensure
44 that r=r is handled correctly. This changes behavior a bit. If term
45 should not be converted to @and, then instead of r=r one should use
48 Construct md-pages-number form page/endpage PAZ-998
52 solr-pz2.xsl: extend Solr transformation to emit license_name field PAZ-996
54 cf.xsl: forwards flat affiliation structure PAZ-992
56 parpar2: log YAZ version upon start PAZ-993
58 Update and fix documentation for preferred targets
60 Fix spelling of present_chunk in documentation
64 Increase facet limit PAZ-990
65 No longer a limit on facets.
67 Pazpar2-js no longer requires Apache2 PAZ-989
68 Package pazpar2-apache2 sets up everything WRT apache and only
69 package which requires it. pazpar2-apache depends on pazpar2-js.
73 Larger string buffer for forward address PAZ-987
74 Fixes buffer overflow that could occur if forward address is IPV6.
76 Updates to Windows NMAKE makefile for Visual Studio 2013.
80 Use YAZ backtrace facility PAZ-983. In case of crashes YAZ log may
81 include more details about the fault. Better install gdb and the
82 debug version of pazpar2 (pazpar2-dbg on Debian/Ubuntu).
84 Per target timeout PAZ-981
85 New setting pz:timeout which overrides z3950_operation timeout
90 Re-introduce journal-subpart PAZ-980
91 Both citation and journal-subpart have same value.
95 Add Ubuntu utopic 14.04 and Ubuntu saucy 13.10 to the list of packages
98 Remove from js/pz2.js the code that translates just two diagnostic
99 codes (1 and 2) into human-readable messages. This is no longer
100 necessary at all, as PazPar2 has been returning the message as well as
101 the code in its responses since December 2012. Fixes PAZ-978.
103 primo xsl produces citation rather than journal-subpart PAZ-972
104 (fix in 1.8.1 was incorrect)
106 Fix missing .url files PAZ-977
107 Add missing .url+.cfg and add proper check for it.
111 Turbomarc needs number check for date 903 map PAZ-973
113 primo-pz2.xsl creates citation rather than journal-subpart PAZ-972
115 pz2.js: on successful search, issue a "show" command only if a show
116 callback function has been installed. Fixes part of PAZ-975
120 New command=stop which stops further search&retrieval for active
123 CF/primo XSL generates {volume,issue,pages}-number that are defined
124 in default Pazpar2 service definition. PAZ-968 PAZ-970
128 Various fixes for threaded operation PAZ-960 thru PAZ-966
130 Dump main configuration file during start of Pazpar2 PAZ-957
134 Log ingest failures and record failures:
136 Clean up logging PAZ-942
137 Use session lead in more places. Log hits/records/filtered for each
138 target when fetching is complete. Log hit count when a search
139 (response) is received. Remove some less useful log messages.
141 Fix warning about about missing (internal) stylesheet PAZ-956
143 Report number of filtered records in bytarget PAZ-954
145 Cache XML documents as they appear after normalization. The key
146 for the cache is database+record offset. Cache is removed if query
147 is modified for search. This speeds up re-establishing a result set
148 for databases where new query is same previous query.
152 poll: add assert for number of FDs; abort on poll failure
156 Fix hang for 2nd use of target with unresolved DNS PAZ-949
160 Use poll rather than select for main event loop to overcome limit of
161 1024 file descriptors PAZ-947
163 Override setting with same name (do not append) PAZ-945
167 Separate package: pazpar2-xsl PAZ-932
169 --- 1.6.44 2014/06/27
171 Update OPAC stylesheets for availabilityDate PAZ-943
173 Fix too funny startrecs description
175 Fix broken ~ match if filter contains = PAZ-941
177 --- 1.6.43 2014/06/12
179 Add pz:redis option for ZOOM caching using redis. This is an alternative
180 to memcached. Requires YAZ 5.2.0 to work.
182 --- 1.6.42 2014/05/06
184 Re-ingest native facets PAZ-934
186 Fix medium override for solr-pz2.xsl.
188 --- 1.6.41 2014/04/23
190 Fix URL with leading http:// not working PAZ-933
192 Build packages for Ubuntu Trusty Tahr 14.04 LTS
194 cf.xsl: handle medium override AND md field
196 --- 1.6.40 2014/04/10
198 sortmap relevance always uses increasing=1. PAZ-930
200 solr-pz2.xsl: ensure medium is also applied if Solr record do not
203 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
204 this code is only executed once.
206 Fix typos is sortmap documentation.
208 Doc: fix misplaced variablelist tag.
210 --- 1.6.39 2014/02/19
212 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
213 It's been like that since version 1.1.1 from August 2009.
215 Add support for result-set caching via memcached. See description of
216 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
218 Add support for a <metadata> container tag. Patfh from Sven Porst.
220 Add support for XInclude in main configuarion file. Patch from Sven Porst.
222 Add client_{lock,unlock} before call to non_block_events in
223 connection_continue. Problem is that if non_block_events fire records,
224 then we will not unlock client at all. And as a result, a dead-lock
227 --- 1.6.38 2014/01/07
229 Avoid removing slash and other characters for generic metadata that
230 looks like a URL (contains ://). PAZ-915
232 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
234 Cluster merge fixes. PAZ-901
236 Set client state to "working" when waiting for DNS resolver. PAZ-907
238 Log when session terminates. PAZ-905
240 Fix LSB/HS conformance for /etc/init.d/pazpar2 PAZ-904
241 Debian: add support for /etc/init.d/pazpar2 status
243 --- 1.6.37 2013/11/18
245 Fix 'Record Missing' for command=show PAZ-903
247 Preserve order of records within cluster PAZ-902
249 testing: use yaz-ztest -V if possible and use YAZ in sibling directory
252 Allow clustered records to be ingested during retrieval. PAZ-900
254 Fix void function error which cannot return a value.
256 --- 1.6.36 2013/11/11
258 SRU pz:authentication="a/b" may end up as x-username=a%2Fb PAZ-899
260 Upgrade to debhelper version 7 PAZ-898
262 Package with libyaz5 PAZ-897
264 Better error message for CCL parse errors PAZ-887
266 --- 1.6.35 2013/09/23
268 New target setting: pz:authentication_mode. PAZ-896
270 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
272 Strip #-suffix for ZOOM URLs. PAZ-892
274 --- 1.6.34 2013/08/30
276 Fix issue with hanging show/bytarget. Could happen if new search was
277 fired with filter before show from previous show completed.
279 Add 'date' handling for solr-pz2.xsl.
281 --- 1.6.33 2013/08/13
283 pz:authentication may carry user group password. If pz:authentication
284 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
285 authentication. Two forms are allowed
288 If no blanks are present, open authentication is in use (as before).
290 Fix {prev,next}recid elements that are returned by record
291 command. These were incorrect in versions 1.6.23 thru 1.6.32.
293 --- 1.6.32 2013/06/14
295 Experimental support for snippets. If argument snippets=1 is given
296 for command record or show, the text will include <match>-tags for
297 those area that matches.
299 Fix memory leak WRT client structures (incorrect inc ref count).
301 Log when a HTTP response is serialized and the time elapsed.
303 New command, service, which returns current service XML in use for
306 --- 1.6.31 2013/05/24
308 Local limit for fields of type "generic" (ie text fields) are
309 now normalized by mergekey rule before comparison takes place.
310 Before, no normalization took place and comparsion was, thus, exact.
312 New facility: dynamic rank , which allows ranking to be changed
313 for an existing result set. The rank can be set for search or
314 show. This overrides the rank for metadata elements (which fields
317 New facility:dynamic mergekey , which allows mergekey to be changed
318 for an existing result set. The mergekey can be set for search or
321 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
322 Also, allow ports to be given as names (not just integers).
323 Fix @-notation on systems that don't support IPV6 sockets.
325 --- 1.6.30 2013/04/26
327 Add MasterKey Connect configuration. Refer to section "non-standard
328 databases" for more information.
330 Allow timeformat for log to be specified with option -m (as Metaproxy
333 New Debian package pazpar2-dbg.
335 Fix NULL ptr reference of se->relevance. If a new search is initiated
336 and a CCL query fails to parse, Pazpar2 could crash.
338 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
339 existed in 1.6.29 only.
341 --- 1.6.29 2013/04/05
343 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
344 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
345 changed by setting "host" attribute for the "listen" element.
347 Change semantics of pz:extendrecs. Allow for repeated fetches .
348 pz:extendrecs is now the number of extra records to fetch (was total
351 --- 1.6.28 2013/03/21
353 Fix hang or memory violation if show occurred before a search. (not that
354 it makes much sense to perform a show before a search).
356 --- 1.6.27 2013/03/08
358 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
361 --- 1.6.26 2013/03/08
363 New pz:metadata attribute, empty="empty-value" for Pazpar2's
364 internal representation. With this attribute, Pazpar2 treates an empty
365 pz:metadata type as having the value for "empty" - if empty.
367 New setting, pz:extendrecs, which triggers extended fetch of records
368 for a database beyond pz:maxrecs for a show command.
370 Fix warning that was falsely issued for "missing limitmap".
372 Log message for Pazpart start/stop changed. Now using same style as
373 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
375 --- 1.6.25 2013/02/07
377 Fix hang of 2nd command=show with esn/syntax given.
379 --- 1.6.24 2013/01/18
381 New merge attribute type: 'first', which takes all metadata fields
382 from first target that returns the particular field.
384 --- 1.6.23 2013/01/02
386 Extend info command with hostname and YAZ SHA1
387 Indent results for both command stat and info.
389 Allow limit on merged content. The new configuration metadata
390 element, limitcluster, configures that a metadata element (name) be used
391 as limit name for search. Applies to the whole service (ie all targets),
392 unlike pz:limitmap which is configured per-target (database).
394 New feature: limitmap local:* matches against all metadata fields.
396 Allow repeated list in limitmap spec . Separated by comma. For
397 example: value="local:title,rpn:@attr 1=4".
399 New element <message> in bytarget response. Holds diagnostic message
400 of code (say 'Unsupported Use Attribute' for Bib-1 114).
402 Improved logging for record ingestion failures.
404 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
405 when YAZ is compiled without ICU support.
407 --- 1.6.22 2012/10/11
409 Requires YAZ-4.2.40 to support native solr support.
411 Fix and improve logic handling whether or not to re-do search on sort
412 order changes. A sort order with change in ascending/descending only
413 whould not trigger a new search, which is required for targets with
414 native sorting capabilities. Each client is now checked if instructions
415 (sortmap) exist for native sorting and only client that does requires
416 it is researched. Other clients is just re-ingesting the records,
417 they already have. The resultset is now cleared if any researching
420 Connection sharing between session has broken since version 1.6.8 with
421 introduction of logic that would minimize searching if pazpar2 could
422 detect this based on same query and limits and partly sort order.
423 This could lead to segementations violations.
425 Added a chapter in the manaul about relevance ranking.
427 --- 1.6.21 2012/09/24
429 Rank tweak: follow=number will increase mult by number if two terms
430 occur next to each other; number-1 if they are one term apart , .. 0
431 if they are number a part (all in order). Default is 0 (following
432 terms has no effect).
434 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
435 value given by lead and l is length from beginning of field where
436 term occurs (l=0 for first term, l=1 for second term, ..). Default
439 Rank tweak: length=strategy. length="linear" if mult is to be divided
440 by length (existing, default behavior), length="log" if mult is to be
441 divided by log2(1+length), length="none" if mult is not to be affected
444 --- 1.6.20 2012/09/21
446 Rank algorithm details may be printed as part of show response in
447 element <relevance_info>.. This is only printed if <rank debug="yes"/>
450 Record as returned by show/record command have a minimal indentation
451 which makes things human-readable.
453 New configuration of default sorting criteria (sort-default) in
454 service definition. If no criteria is defined it will be as before
457 Search command now supports sort parameter just as the show command.
458 If no parameter is give, it will use the service sort-default value.
460 --- 1.6.19 2012/09/18
462 Rank algorithm skips strings that gets normalized to empty string.
463 For example, & and ! could map to the empty string. The weight for
464 those terms is now 0 (as if they were not part of the query).
466 Rank algorithm does not use CCL from limitmap; only from the query
467 parameter (user query).
471 --- 1.6.18 2012/09/17
473 Rank algorithm configurable by 'rank' element inside service. So far
474 only, attribute 'cluster' is recognized. If cluster="yes", multiple
475 records inside a cluster boosts higher than single records. This
476 is default behavior and existing behavior. cluster="no" takes the
477 average score of each record in a cluster.
479 --- 1.6.17 2012/09/05
481 Fix bad re-use of connections (connections with changing proxy should not
484 --- 1.6.16 2012/08/22
486 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
487 resultset and sorting when the sort order is position. However this will be done on
488 every client poll, which will make pazpar2 continuing reset and fetching.
489 It should only be done on FIRST request where the sort order change.
491 Fix an issue on suggestion option: Also disable suggestions on empty string.
493 Clean up in turbo marc stylesheet.
495 Remove the hardcoded size of termlists.
497 --- 1.6.15 2012/06/27
499 New facility: ccldirective may be given in service definition. Allows
500 CCL parsing to be customized a bit, such as defining names of operators
503 New facility: raw record by checksum, rather than offset. The record
504 command optionally takes checksum which identifies certain record from
507 New facility: per field ranking. Rank may be given as M [F N] where
508 M is default rank and N is rank for CCL terms from field F.
510 --- 1.6.14 2012/06/04
512 Fix for IE7/8 in pz.js
514 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
516 Lower log level some places.
518 Remove some invalid test results.
520 --- 1.6.13 2012/05/23
522 Introducing a version=2 parameter for show, termlist and bytarget commands.
523 This enables pazpar2 to return approximation on hit and count count when
524 doing record filtering using the limit parameter on search and a
525 limitmap with a value of "local:"
527 Setting pz:xslt may embed local XSLT as an alternative to referring
529 Value is not CDATA but XML nodes embedded, so escaping is not necessary
530 but a root element *must* be present. For example:
531 <settings target="target="z3950.indexdata.com/marc">
540 Metadata field rank may given by XML internal document (pz:xslt
541 result). If rank is not given, the rank from service description is
544 Metadata field can now configured a default limitmap and facetmap.
545 Setting limitmap to "local:" would work for all kind of targets, but would
546 prob. not be the optimal solution. But at least better than the default behavior
547 of pazpar2 where no filtering is done.
549 A service definition can now also contains <set/> that defines service-wide
550 settings. These will override server-wide sets and will be overridded by
553 New setting, pz:present_chunk, that specifies number of records to fetch
554 at a time. Zero will disable chunkation; will fetch max_records at once.
556 --- 1.6.12 2012/03/14
558 Revert the format change in termlist response, that could break
559 some clients / UIs since they were expecting an (empty) element
560 if no facet values was found.
562 --- 1.6.11 2012/03/07
564 Revert the behavior of returning errors when unable to block
565 on termlist, bytarget and search, when unable to block due to
566 other block. The client will now receive a regular response,
567 but it will be logged in the server. A parameter (report) is
568 added to change behavior to return error response or WARNING
569 status message. Consider this "API" as private, as it is mostly
570 untested and could be changed in future releases.
572 Fix spell error in pz2.js fix in 1.6.10.
574 New Marc2TurboMarc.xsl (contribution from Sven Porst).
575 Can solve the missing marc21.xsl updates in some cases.
577 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
578 substring (contribtion from Sven Porst)
580 marc21.xsl: fix 1-based substring call
582 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
584 Add test_termlist_block to test suite
586 --- 1.6.10 2012/02/23
588 Fix SEGV for invalid PQFs and SRU/SOLR targets
589 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
591 Fix pz2.js: "null object" due to change in in bytarget result XML.
593 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
594 Added this normalization to the other subject-long fields (d6xx),
595 where it was missing.
597 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
598 Still differences around medium and holdings. marc21.xsl is not
599 longer active used by Index Data, and should be considered unsupported.
600 Use tmarc.xsl instead.
604 Fix SEGV that could occur for failed connections.
608 Fix bug for command sort that could return no results for active clients
609 (from previous search). This bug was present in 1.6.6-1.6.7.
611 Fix bug in results that could include results that should have been
612 filtered out. This bug was present in 1.6.6-1.6.7.
616 Fix bug introduced in 1.6.6 where a connection re-use could stall
619 Local filtering may now specify a local metadata field, eg.
620 pz:limitmap:somefield[t]=local:otherfield
624 For search, when limit and or filtering is in place and search
625 is identical to previous search, the result set is re-used and the
626 target is not searched.
628 Limits may work perform local filtering as well, by using "local:"
633 Updated bytarget command to contain a suggestions element with misspelled
634 words and suggestions to these. pz2.js has been updated to deliver this
635 onwards as well. Only target that currently delivers this is the solr
636 client in YAZ 4.2.18.
640 New service definition element, xslt, that allows an embedded stylesheet
641 to be defined. This can be referred to from pz:xslt as an alternative to
644 New pz:sortmap:field setting for specifying hints on how to make
645 a target natively sort on a field. This is used for command=show in
646 conjunction with sort.
648 New pz:url setting for specifying the actual URL for a target. When
649 this is used the target ID is not used as URL anymore and the target ID
650 may be almost any string (not including []).
652 command=termlist without name parameter returns all termlists/facets.
653 Previously if name parameter was omitted, only "subject" was returned.
657 Make termlist sorting stable. Terms with same frequency are now sorted by
658 their display name. This makes a pretty display and improves our
659 regression test because qsort is not a stable sort.
661 New sort parameter value 'position'. The 'position' sorts merged records
662 by their original position from the remote target. This is primarily useful
663 for debugging and may be used for targets that already perform some kind
664 of relevance ranking. Note that sort by default is decreasing; so to get
665 records in their original order sort=position:1 must be used.
669 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
671 Facility to change working directory for pazpar2 daemon. Option -wdir
672 sets working directory to dir. This facility is useful if core dumps
673 must be saved. In this case, the current working directory must be
674 writable by the running user, such as "nobody".
678 New configuration element <icu_chain> for <server>/<service> which
679 allows a named ICU rule (chain) to be defined. The names relevance,
680 sort, mergekey and facet are used for those operations. The definition
681 <icu_chain id="sort" locale="en"> .. </icu_chain>
683 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
684 And so on.. for relevance, mergekey and facet as well. The latter
685 style is deprecated. The facet terms are normalized by the facet
686 rule by default. This may be changed on a metadata field basis by
687 defining the new attribute 'facetrule' for the metadata element.
689 <icu_chain id="myrule" locale="en"> ... </icu_chain>
690 <metadata name="author" termlist="yes" facetrule="myrule"/>
692 Preserve rorder for merged metadata. Fixes issue as reported by Sven
693 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
695 tmarc.xsl: set journal-subpart to 773$ only.
699 Modify the behavior for the limit parameter (first defined in 1.5.7).
700 Mapping of limit searches are now defined by the new configuration item
701 pz:limitmap. Fix a dead-lock problem with the limit parameter.
703 Extend tmarc.xsl to extract 773$g data (OpenURL).
707 ICU default maps remove backquote (`).
709 Command 'search' takes limit parameter (optional). The limit parameter
710 allows a search to be limited one or more facets and the corresponding
711 values. This is for server side filtering.
713 Configure tweak: Use -lm for log(3) if needed
717 Fix a problem with skiparticle sortkey that could be completely
718 ignored (and reduced to "").
720 Fix dependency problem in pazpar2 RPM package (did not require
721 libyaz4 as it should).
725 Fix memory leak that occurred for command=termlist&name=xtargets .
727 Pazpar2 may save HTTP requests. Enabled by option -R.
731 Experimental support for DTIC DADS target. New dads-pz2.xsl.
733 Support for query_syntax (overrides the default for SRU | Z39.50)
735 Support for extraArgs (ZOOM "extraArgs" option) for targets
737 New commands: status-server and status-session
741 Fix for threaded runs: Client now have a copy of the database URL,
742 which can used after the database has been release from the client.
743 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
745 tmarc.xsl: Add journal-title-abbrev and full text.
747 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
749 Fix for cmd=record before search.
751 Session Logging clean up.
753 Fix wrong termlist factor when maxrecs is different from 100.
757 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
758 Term factor is default enabled but can be diseabled by
759 pz:termlist_term_factor=0
763 Add scaling of facet count. Currently always enabled, needs fixing.
764 Allow user-defined info for target suffix. This has no meaning in
765 Pazpar2 except to distinguish targets from each other. The suffix
766 data begins with #. For example z3950.indexdata.com/gils#Mydata
768 Added exact-match recordfilter; format name=value
772 SOLR support. Pazpar2 may operate as web service client for SOLR.
776 Fix for show command and block=1 (dead lock). Bug was introduced in
781 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
782 tested on CentOS 5.5 only.
786 Fix problem with result sets being removed from a client session
787 if the connection for it was resused by another session. Bug #3489.
789 New iphone UI for Pazpar2 (www/iphone).
793 Fixes for threaded operation.
795 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
797 New example services in etc/services in source. In the Debian packages
798 these are located in /etc/pazpar2/services-available
800 Threaded mode operational on Windows. Requires Windows 7 or Windows
803 Default value of setting pz:max_connections is 0 which means that there
804 is no limit on number of connections.
808 Pazpar2 may operate in threaded mode. Enabled by element threads in
809 the configuration. See pazpar2_conf for details.
811 New setting setting: pz:max_connections. Setting pz:max_connections is
812 a limit of number of sockets to a host. When this limit is reached,
813 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
814 The client will be marked Client_Error when it can not be searched
815 (other clients in a session may work). If pz:max_connections is not set
816 for a target, a value of 30 will be used. Note: the pz:max_connections
817 will only work in threaded mode.
819 pz2.js: JSON support for show.
821 Debian package: Enable default service, default.xml, before starting
822 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
826 Debian version depends on on libyaz4. Note that Pazpar2 will still
827 compile from source with YAZ 3.
829 Split services into separate files. The example configuration file
830 pazpar2.cfg.dist now includes a default service default.xml (part of
831 etc). And default.xml includes settings/edu.xml. The default.xml file,
832 not to be confused with settings/defaults.xml, is a template for jsdemo
833 and other services. The Debian package installs /etc/pazpar2/server.xml
834 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
835 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
836 The default.xml (from etc) is installed in /etc/pazpar2/services-available
837 and a symlink to it is created from services-enabled. The default.xml
838 service is unnamed and, thus, will be used by jsdemo and test1.
840 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
841 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
845 Support for additional fields in cf.xsl and pazpar2.conf.dist:
846 publisher, available, due, location (=locallocation), callno
847 (=callnumber), thumburl and score.
849 Describe pz:xslt and the auto setting.
851 Move mergekey definition away from the normalization stylesheets and
852 define a mergekey common for all target types in pazpar2.cfg.
854 Code update: Use the Odr_int type for hit counts. This is part of
855 YAZ 3.0.47 and later and so configure checks for that.
859 Metadata attribute 'skiparticle' also works for ICU based
860 normalization. (was only working for the non-ICU/ASCII before).
862 Command bytarget with argument settings=1 will show settings per
863 target.. This is to be able to verify correct settings and be able to
864 test that they are correct. The database settings array size is now
865 also stored.. Problems with database settings array is that if not
866 careful it will be too small (smaller than dictionary per-service
869 Make record list sorting stable by comparing mergekey for records if
870 relevance/title or other sorting criteria all match. This is merely to
871 ensure that our regressions tests works (reproducible output).
873 Relevance calculation changes: use a different denominator (length) for
874 per-field relevance scoring.. Instead of length of all ranked fields we
875 now use length of individual fields (as if they were individual "free"
876 text fields). This will ensure that documents with a long field with no
877 match (say description) will not "hurt" a title match.
879 Diagnostic member was not set on connection error. Fixed
883 Command search takes two optional parameters, startecs and maxrecs,
884 that specifies the start offset (0, 1, ...) and maximum number of records
885 to fetch for each target.
887 XSLTs + MARC maps are cached within a session so we don't re-parse
888 them over and over again. Even for a session with a single search
889 there's much to be gained because many targets use the same
892 The metadata attribute 'mergekey' now takes one of three values 'no',
893 'required', 'optional' . And the resulting mergekey from metadata
894 is now ordered in the same way as metadata in the service definition.
895 Older Pazpar2 version use the order in which metadata appeared in a
898 The search argument 'filter' now offers a new operator ~ which does a
899 substring match. The = operator works as before: string match for
900 anything but pz:id, or target match for pz:id.
902 New setting pz:recordfilter. The value of this setting takes the
903 form name[~value]. This setting makes Pazpar2 ignore all retrieved
904 records that do not have the metadata element name with value substring
907 Pazpar2 allows YAZ log level to be set (option -v).
911 For WS responses Pazpar2 creates XML header. Exception: raw record.
913 Setting XML files are now stored in etc/settings instead of etc. This
914 reflects the layout with the Debian package layout.
916 Settings may be posted for command=settings. The POSTed settings must
917 have root element 'settings' like regular setting files. In order to be
918 recognized, the POST request must use Content-Type=text/xml.
920 A service may be posted for command=init. This service will be used
921 during the session. The service may have its own target settings,
922 ICU config, timeout, etc. In order to be recognized, the POST request
923 must use Content-Type=text/xml.
925 Timeout values may be given per-service. That's element 'timeout'
926 which takes three attribute values (a subset may be given): 'session',
927 'z3950_operation', 'z3950_session'. Option -T is no longer supported
928 - used to specify session timeout.
930 Option -t tests the Pazpar2 configuration and returns exit code
931 (0=success, non-zero=failure). In previous version of Pazpar2, -t
932 specified local settings.
934 In version 1.2.0 the configuration file - after include processing -
935 was dumped to stdout. Now, the configuration is only dumped to the
936 yaz log file if option -d is given.
940 Configuration may now have multiple server areas. This means that a
941 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
942 yet supported - on a server basis. Configuration may also have multiple
943 services .. That is repeating service elements inside a server. Each
944 has an attribute 'id' which serves as service ID. This ID in turn may
945 be used in a Pazpar2 session, by specifying parameter service=ID for
946 command init. There can be at most one unnamed service inside a server
947 which can be referred to by not specifying an service ID for command
948 init (backwards compatible). In order to partition multiple servers and
949 services a new include directive has been added. This takes an attribute
950 'src' which specifies one or more sub-files. For example to include
951 service files, one might use:
952 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
953 It is the intention that that completely makes the settings directive
956 Fix problem where the record command would wait forever if there were
957 no targets to wait for (activeclients == 0).
961 One result set is created per session (last search) rather than for
962 each connection which happen to be shared (bug #3009).
964 marc21 stylesheets changed for efficiency.
968 Session timeout may be specified on the command-line as option -T.
970 Pazpar2 may now be operated in a no-merged mode for records.. All records
971 will be considered unique. This mode is enabled if no mergekey is
972 generated by the normalization stylesheet (pz:xslt).
974 Pazpar2 caches original records from each target and the 'record' command
975 with offset returns the original record if 'syntax' and 'esn' are NOT
976 specified. This speeds up retrieval of original records but also means
977 that Pazpar2 uses more memory. The cached records will be freed when the
978 session terminates or a new search is executed.
980 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
981 library part of YAZ is used.
983 Added SRU client support.
985 Automatically computes pz:nativesyntax if not provided. Works for XML and
988 --- 1.0.13 2008/11/24

1006 --- 1.0.9 2008/05/23
1008 Changed the JS library pz2.js to use POST for long URL (+ params).
1010 Added installation instructions for Windows. Note: NT services is
1011 NOT available until we make a new release of YAZ.

1027 --- 1.0.6 2008/03/12
1029 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1031 Fixed bug 2100: Database wildcards not working
1033 --- 1.0.5 2007/11/09
1035 Added support for retrieval of records in binary.
1037 Fixed bug 1794: Pazpar2 does not return valid XML.
1039 Deal with ICU not returning sortkey (resulted in SEGV before).
1041 --- 1.0.4 2007/09/28
1043 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1044 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1046 Improved diagnostics when Pazpar2 HTTP decoding fails.
1048 Pazpar2 requests may be POSTed as using Content-Type
1049 application/x-www-form-urlencoded.
1051 Pazpar2 honors LF in HTTP headers.
1053 Handle targets that handle negative hit counts (should not happen, but it
1056 --- 1.0.3 2007/09/19
1058 ICU is used for tokenization and normalization of the following: mergekey,
1059 sorting, relevance terms.
1061 Debian package now enables ICU tokenization and normalization by default.
1063 --- 1.0.2 2007/08/22
1065 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1066 ways: Either as parameters to the normalization stylesheets (which would allow the
1067 programmer to postprocess or use the values in any way) or after the normalization
1068 step, in which case values are made part of the normalized record (and available for
1069 sorting, termlists, display, or other interface-related use.
1071 Implemented sorting by year.
1073 Option -d dumps records to the current log file instead of stderr.
1075 Fixes for compilation on cygwin.
1077 Z39.50 client code uses pz:elements. pz:elements was recognized in
1078 earlier Pazpar2 versions but it was not used for anything.
1080 icu_chain_test is using fgets instead of getline - fixes compilation
1083 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1084 query conversions fail (rather than _any_). This means targets that do
1085 not support some fields are ignored in a search.
1087 --- 1.0.1 2007/07/03
1089 Improved handling of socket timeout for Z39.50 connections.
1091 Misc documentation updates and spell fixes.
1093 Debian package pazpar2 creates log rotate entry.
1095 Debian package pazpar2-apache2 reloads Apache2.
1097 jsdemo included in distribution. It illustrates the use of the js/pz2.js
