3 Various fixes for threaded operation PAZ-960 thru PAZ-966
5 Dump main configuration file during start of Pazpar2 PAZ-957
9 Log ingest failures and record failures:
11 Clean up logging PAZ-942
12 Use session lead in more places. Log hits/records/filtered for each
13 target when fetching is complete. Log hit count when a search
14 (response) is received. Remove some less useful log messages.
16 Fix warning about about missing (internal) stylesheet PAZ-956
18 Report number of filtered records in bytarget PAZ-954
20 Cache XML documents as they appear after normalization. The key
21 for the cache is database+record offset. Cache is removed if query
22 is modified for search. This speeds up re-establishing a result set
23 for databases where new query is same previous query.
27 poll: add assert for number of FDs; abort on poll failure
31 Fix hang for 2nd use of target with unresolved DNS PAZ-949
35 Use poll rather than select for main event loop to overcome limit of
36 1024 file descriptors PAZ-947
38 Override setting with same name (do not append) PAZ-945
42 Separate package: pazpar2-xsl PAZ-932
46 Update OPAC stylesheets for availabilityDate PAZ-943
48 Fix too funny startrecs description
50 Fix broken ~ match if filter contains = PAZ-941
54 Add pz:redis option for ZOOM caching using redis. This is an alternative
55 to memcached. Requires YAZ 5.2.0 to work.
59 Re-ingest native facets PAZ-934
61 Fix medium override for solr-pz2.xsl.
65 Fix URL with leading http:// not working PAZ-933
67 Build packages for Ubuntu Trusty Tahr 14.04 LTS
69 cf.xsl: handle medium override AND md field
73 sortmap relevance always uses increasing=1. PAZ-930
75 solr-pz2.xsl: ensure medium is also applied if Solr record do not
78 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
79 this code is only executed once.
81 Fix typos is sortmap documentation.
83 Doc: fix misplaced variablelist tag.
87 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
88 It's been like that since version 1.1.1 from August 2009.
90 Add support for result-set caching via memcached. See description of
91 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
93 Add support for a <metadata> container tag. Patfh from Sven Porst.
95 Add support for XInclude in main configuarion file. Patch from Sven Porst.
97 Add client_{lock,unlock} before call to non_block_events in
98 connection_continue. Problem is that if non_block_events fire records,
99 then we will not unlock client at all. And as a result, a dead-lock
102 --- 1.6.38 2014/01/07
104 Avoid removing slash and other characters for generic metadata that
105 looks like a URL (contains ://). PAZ-915
107 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
109 Cluster merge fixes. PAZ-901
111 Set client state to "working" when waiting for DNS resolver. PAZ-907
113 Log when session terminates. PAZ-905
115 Fix LSB/HS conformance for /etc/init.d/pazpar2 PAZ-904
116 Debian: add support for /etc/init.d/pazpar2 status
118 --- 1.6.37 2013/11/18
120 Fix 'Record Missing' for command=show PAZ-903
122 Preserve order of records within cluster PAZ-902
124 testing: use yaz-ztest -V if possible and use YAZ in sibling directory
127 Allow clustered records to be ingested during retrieval. PAZ-900
129 Fix void function error which cannot return a value.
131 --- 1.6.36 2013/11/11
133 SRU pz:authentication="a/b" may end up as x-username=a%2Fb PAZ-899
135 Upgrade to debhelper version 7 PAZ-898
137 Package with libyaz5 PAZ-897
139 Better error message for CCL parse errors PAZ-887
141 --- 1.6.35 2013/09/23
143 New target setting: pz:authentication_mode. PAZ-896
145 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
147 Strip #-suffix for ZOOM URLs. PAZ-892
149 --- 1.6.34 2013/08/30
151 Fix issue with hanging show/bytarget. Could happen if new search was
152 fired with filter before show from previous show completed.
154 Add 'date' handling for solr-pz2.xsl.
156 --- 1.6.33 2013/08/13
158 pz:authentication may carry user group password. If pz:authentication
159 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
160 authentication. Two forms are allowed
163 If no blanks are present, open authentication is in use (as before).
165 Fix {prev,next}recid elements that are returned by record
166 command. These were incorrect in versions 1.6.23 thru 1.6.32.
168 --- 1.6.32 2013/06/14
170 Experimental support for snippets. If argument snippets=1 is given
171 for command record or show, the text will include <match>-tags for
172 those area that matches.
174 Fix memory leak WRT client structures (incorrect inc ref count).
176 Log when a HTTP response is serialized and the time elapsed.
178 New command, service, which returns current service XML in use for
181 --- 1.6.31 2013/05/24
183 Local limit for fields of type "generic" (ie text fields) are
184 now normalized by mergekey rule before comparison takes place.
185 Before, no normalization took place and comparsion was, thus, exact.
187 New facility: dynamic rank , which allows ranking to be changed
188 for an existing result set. The rank can be set for search or
189 show. This overrides the rank for metadata elements (which fields
192 New facility:dynamic mergekey , which allows mergekey to be changed
193 for an existing result set. The mergekey can be set for search or
196 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
197 Also, allow ports to be given as names (not just integers).
198 Fix @-notation on systems that don't support IPV6 sockets.
200 --- 1.6.30 2013/04/26
202 Add MasterKey Connect configuration. Refer to section "non-standard
203 databases" for more information.
205 Allow timeformat for log to be specified with option -m (as Metaproxy
208 New Debian package pazpar2-dbg.
210 Fix NULL ptr reference of se->relevance. If a new search is initiated
211 and a CCL query fails to parse, Pazpar2 could crash.
213 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
214 existed in 1.6.29 only.
216 --- 1.6.29 2013/04/05
218 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
219 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
220 changed by setting "host" attribute for the "listen" element.
222 Change semantics of pz:extendrecs. Allow for repeated fetches .
223 pz:extendrecs is now the number of extra records to fetch (was total
226 --- 1.6.28 2013/03/21
228 Fix hang or memory violation if show occurred before a search. (not that
229 it makes much sense to perform a show before a search).
231 --- 1.6.27 2013/03/08
233 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
236 --- 1.6.26 2013/03/08
238 New pz:metadata attribute, empty="empty-value" for Pazpar2's
239 internal representation. With this attribute, Pazpar2 treates an empty
240 pz:metadata type as having the value for "empty" - if empty.
242 New setting, pz:extendrecs, which triggers extended fetch of records
243 for a database beyond pz:maxrecs for a show command.
245 Fix warning that was falsely issued for "missing limitmap".
247 Log message for Pazpart start/stop changed. Now using same style as
248 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
250 --- 1.6.25 2013/02/07
252 Fix hang of 2nd command=show with esn/syntax given.
254 --- 1.6.24 2013/01/18
256 New merge attribute type: 'first', which takes all metadata fields
257 from first target that returns the particular field.
259 --- 1.6.23 2013/01/02
261 Extend info command with hostname and YAZ SHA1
262 Indent results for both command stat and info.
264 Allow limit on merged content. The new configuration metadata
265 element, limitcluster, configures that a metadata element (name) be used
266 as limit name for search. Applies to the whole service (ie all targets),
267 unlike pz:limitmap which is configured per-target (database).
269 New feature: limitmap local:* matches against all metadata fields.
271 Allow repeated list in limitmap spec . Separated by comma. For
272 example: value="local:title,rpn:@attr 1=4".
274 New element <message> in bytarget response. Holds diagnostic message
275 of code (say 'Unsupported Use Attribute' for Bib-1 114).
277 Improved logging for record ingestion failures.
279 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
280 when YAZ is compiled without ICU support.
282 --- 1.6.22 2012/10/11
284 Requires YAZ-4.2.40 to support native solr support.
286 Fix and improve logic handling whether or not to re-do search on sort
287 order changes. A sort order with change in ascending/descending only
288 whould not trigger a new search, which is required for targets with
289 native sorting capabilities. Each client is now checked if instructions
290 (sortmap) exist for native sorting and only client that does requires
291 it is researched. Other clients is just re-ingesting the records,
292 they already have. The resultset is now cleared if any researching
295 Connection sharing between session has broken since version 1.6.8 with
296 introduction of logic that would minimize searching if pazpar2 could
297 detect this based on same query and limits and partly sort order.
298 This could lead to segementations violations.
300 Added a chapter in the manaul about relevance ranking.
302 --- 1.6.21 2012/09/24
304 Rank tweak: follow=number will increase mult by number if two terms
305 occur next to each other; number-1 if they are one term apart , .. 0
306 if they are number a part (all in order). Default is 0 (following
307 terms has no effect).
309 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
310 value given by lead and l is length from beginning of field where
311 term occurs (l=0 for first term, l=1 for second term, ..). Default
314 Rank tweak: length=strategy. length="linear" if mult is to be divided
315 by length (existing, default behavior), length="log" if mult is to be
316 divided by log2(1+length), length="none" if mult is not to be affected
319 --- 1.6.20 2012/09/21
321 Rank algorithm details may be printed as part of show response in
322 element <relevance_info>.. This is only printed if <rank debug="yes"/>
325 Record as returned by show/record command have a minimal indentation
326 which makes things human-readable.
328 New configuration of default sorting criteria (sort-default) in
329 service definition. If no criteria is defined it will be as before
332 Search command now supports sort parameter just as the show command.
333 If no parameter is give, it will use the service sort-default value.
335 --- 1.6.19 2012/09/18
337 Rank algorithm skips strings that gets normalized to empty string.
338 For example, & and ! could map to the empty string. The weight for
339 those terms is now 0 (as if they were not part of the query).
341 Rank algorithm does not use CCL from limitmap; only from the query
342 parameter (user query).
346 --- 1.6.18 2012/09/17
348 Rank algorithm configurable by 'rank' element inside service. So far
349 only, attribute 'cluster' is recognized. If cluster="yes", multiple
350 records inside a cluster boosts higher than single records. This
351 is default behavior and existing behavior. cluster="no" takes the
352 average score of each record in a cluster.
354 --- 1.6.17 2012/09/05
356 Fix bad re-use of connections (connections with changing proxy should not
359 --- 1.6.16 2012/08/22
361 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
362 resultset and sorting when the sort order is position. However this will be done on
363 every client poll, which will make pazpar2 continuing reset and fetching.
364 It should only be done on FIRST request where the sort order change.
366 Fix an issue on suggestion option: Also disable suggestions on empty string.
368 Clean up in turbo marc stylesheet.
370 Remove the hardcoded size of termlists.
372 --- 1.6.15 2012/06/27
374 New facility: ccldirective may be given in service definition. Allows
375 CCL parsing to be customized a bit, such as defining names of operators
378 New facility: raw record by checksum, rather than offset. The record
379 command optionally takes checksum which identifies certain record from
382 New facility: per field ranking. Rank may be given as M [F N] where
383 M is default rank and N is rank for CCL terms from field F.
385 --- 1.6.14 2012/06/04
387 Fix for IE7/8 in pz.js
389 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
391 Lower log level some places.
393 Remove some invalid test results.
395 --- 1.6.13 2012/05/23
397 Introducing a version=2 parameter for show, termlist and bytarget commands.
398 This enables pazpar2 to return approximation on hit and count count when
399 doing record filtering using the limit parameter on search and a
400 limitmap with a value of "local:"
402 Setting pz:xslt may embed local XSLT as an alternative to referring
404 Value is not CDATA but XML nodes embedded, so escaping is not necessary
405 but a root element *must* be present. For example:
406 <settings target="target="z3950.indexdata.com/marc">
415 Metadata field rank may given by XML internal document (pz:xslt
416 result). If rank is not given, the rank from service description is
419 Metadata field can now configured a default limitmap and facetmap.
420 Setting limitmap to "local:" would work for all kind of targets, but would
421 prob. not be the optimal solution. But at least better than the default behavior
422 of pazpar2 where no filtering is done.
424 A service definition can now also contains <set/> that defines service-wide
425 settings. These will override server-wide sets and will be overridded by
428 New setting, pz:present_chunk, that specifies number of records to fetch
429 at a time. Zero will disable chunkation; will fetch max_records at once.
431 --- 1.6.12 2012/03/14
433 Revert the format change in termlist response, that could break
434 some clients / UIs since they were expecting an (empty) element
435 if no facet values was found.
437 --- 1.6.11 2012/03/07
439 Revert the behavior of returning errors when unable to block
440 on termlist, bytarget and search, when unable to block due to
441 other block. The client will now receive a regular response,
442 but it will be logged in the server. A parameter (report) is
443 added to change behavior to return error response or WARNING
444 status message. Consider this "API" as private, as it is mostly
445 untested and could be changed in future releases.
447 Fix spell error in pz2.js fix in 1.6.10.
449 New Marc2TurboMarc.xsl (contribution from Sven Porst).
450 Can solve the missing marc21.xsl updates in some cases.
452 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
453 substring (contribtion from Sven Porst)
455 marc21.xsl: fix 1-based substring call
457 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
459 Add test_termlist_block to test suite
461 --- 1.6.10 2012/02/23
463 Fix SEGV for invalid PQFs and SRU/SOLR targets
464 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
466 Fix pz2.js: "null object" due to change in in bytarget result XML.
468 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
469 Added this normalization to the other subject-long fields (d6xx),
470 where it was missing.
472 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
473 Still differences around medium and holdings. marc21.xsl is not
474 longer active used by Index Data, and should be considered unsupported.
475 Use tmarc.xsl instead.
479 Fix SEGV that could occur for failed connections.
483 Fix bug for command sort that could return no results for active clients
484 (from previous search). This bug was present in 1.6.6-1.6.7.
486 Fix bug in results that could include results that should have been
487 filtered out. This bug was present in 1.6.6-1.6.7.
491 Fix bug introduced in 1.6.6 where a connection re-use could stall
494 Local filtering may now specify a local metadata field, eg.
495 pz:limitmap:somefield[t]=local:otherfield
499 For search, when limit and or filtering is in place and search
500 is identical to previous search, the result set is re-used and the
501 target is not searched.
503 Limits may work perform local filtering as well, by using "local:"
508 Updated bytarget command to contain a suggestions element with misspelled
509 words and suggestions to these. pz2.js has been updated to deliver this
510 onwards as well. Only target that currently delivers this is the solr
511 client in YAZ 4.2.18.
515 New service definition element, xslt, that allows an embedded stylesheet
516 to be defined. This can be referred to from pz:xslt as an alternative to
519 New pz:sortmap:field setting for specifying hints on how to make
520 a target natively sort on a field. This is used for command=show in
521 conjunction with sort.
523 New pz:url setting for specifying the actual URL for a target. When
524 this is used the target ID is not used as URL anymore and the target ID
525 may be almost any string (not including []).
527 command=termlist without name parameter returns all termlists/facets.
528 Previously if name parameter was omitted, only "subject" was returned.
532 Make termlist sorting stable. Terms with same frequency are now sorted by
533 their display name. This makes a pretty display and improves our
534 regression test because qsort is not a stable sort.
536 New sort parameter value 'position'. The 'position' sorts merged records
537 by their original position from the remote target. This is primarily useful
538 for debugging and may be used for targets that already perform some kind
539 of relevance ranking. Note that sort by default is decreasing; so to get
540 records in their original order sort=position:1 must be used.
544 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
546 Facility to change working directory for pazpar2 daemon. Option -wdir
547 sets working directory to dir. This facility is useful if core dumps
548 must be saved. In this case, the current working directory must be
549 writable by the running user, such as "nobody".
553 New configuration element <icu_chain> for <server>/<service> which
554 allows a named ICU rule (chain) to be defined. The names relevance,
555 sort, mergekey and facet are used for those operations. The definition
556 <icu_chain id="sort" locale="en"> .. </icu_chain>
558 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
559 And so on.. for relevance, mergekey and facet as well. The latter
560 style is deprecated. The facet terms are normalized by the facet
561 rule by default. This may be changed on a metadata field basis by
562 defining the new attribute 'facetrule' for the metadata element.
564 <icu_chain id="myrule" locale="en"> ... </icu_chain>
565 <metadata name="author" termlist="yes" facetrule="myrule"/>
567 Preserve rorder for merged metadata. Fixes issue as reported by Sven
568 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
570 tmarc.xsl: set journal-subpart to 773$ only.
574 Modify the behavior for the limit parameter (first defined in 1.5.7).
575 Mapping of limit searches are now defined by the new configuration item
576 pz:limitmap. Fix a dead-lock problem with the limit parameter.
578 Extend tmarc.xsl to extract 773$g data (OpenURL).
582 ICU default maps remove backquote (`).
584 Command 'search' takes limit parameter (optional). The limit parameter
585 allows a search to be limited one or more facets and the corresponding
586 values. This is for server side filtering.
588 Configure tweak: Use -lm for log(3) if needed
592 Fix a problem with skiparticle sortkey that could be completely
593 ignored (and reduced to "").
595 Fix dependency problem in pazpar2 RPM package (did not require
596 libyaz4 as it should).
600 Fix memory leak that occurred for command=termlist&name=xtargets .
602 Pazpar2 may save HTTP requests. Enabled by option -R.
606 Experimental support for DTIC DADS target. New dads-pz2.xsl.
608 Support for query_syntax (overrides the default for SRU | Z39.50)
610 Support for extraArgs (ZOOM "extraArgs" option) for targets
612 New commands: status-server and status-session
616 Fix for threaded runs: Client now have a copy of the database URL,
617 which can used after the database has been release from the client.
618 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
620 tmarc.xsl: Add journal-title-abbrev and full text.
622 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
624 Fix for cmd=record before search.
626 Session Logging clean up.
628 Fix wrong termlist factor when maxrecs is different from 100.
632 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
633 Term factor is default enabled but can be diseabled by
634 pz:termlist_term_factor=0
638 Add scaling of facet count. Currently always enabled, needs fixing.
639 Allow user-defined info for target suffix. This has no meaning in
640 Pazpar2 except to distinguish targets from each other. The suffix
641 data begins with #. For example z3950.indexdata.com/gils#Mydata
643 Added exact-match recordfilter; format name=value
647 SOLR support. Pazpar2 may operate as web service client for SOLR.
651 Fix for show command and block=1 (dead lock). Bug was introduced in
656 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
657 tested on CentOS 5.5 only.
661 Fix problem with result sets being removed from a client session
662 if the connection for it was resused by another session. Bug #3489.
664 New iphone UI for Pazpar2 (www/iphone).
668 Fixes for threaded operation.
670 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
672 New example services in etc/services in source. In the Debian packages
673 these are located in /etc/pazpar2/services-available
675 Threaded mode operational on Windows. Requires Windows 7 or Windows
678 Default value of setting pz:max_connections is 0 which means that there
679 is no limit on number of connections.
683 Pazpar2 may operate in threaded mode. Enabled by element threads in
684 the configuration. See pazpar2_conf for details.
686 New setting setting: pz:max_connections. Setting pz:max_connections is
687 a limit of number of sockets to a host. When this limit is reached,
688 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
689 The client will be marked Client_Error when it can not be searched
690 (other clients in a session may work). If pz:max_connections is not set
691 for a target, a value of 30 will be used. Note: the pz:max_connections
692 will only work in threaded mode.
694 pz2.js: JSON support for show.
696 Debian package: Enable default service, default.xml, before starting
697 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
701 Debian version depends on on libyaz4. Note that Pazpar2 will still
702 compile from source with YAZ 3.
704 Split services into separate files. The example configuration file
705 pazpar2.cfg.dist now includes a default service default.xml (part of
706 etc). And default.xml includes settings/edu.xml. The default.xml file,
707 not to be confused with settings/defaults.xml, is a template for jsdemo
708 and other services. The Debian package installs /etc/pazpar2/server.xml
709 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
710 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
711 The default.xml (from etc) is installed in /etc/pazpar2/services-available
712 and a symlink to it is created from services-enabled. The default.xml
713 service is unnamed and, thus, will be used by jsdemo and test1.
715 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
716 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
720 Support for additional fields in cf.xsl and pazpar2.conf.dist:
721 publisher, available, due, location (=locallocation), callno
722 (=callnumber), thumburl and score.
724 Describe pz:xslt and the auto setting.
726 Move mergekey definition away from the normalization stylesheets and
727 define a mergekey common for all target types in pazpar2.cfg.
729 Code update: Use the Odr_int type for hit counts. This is part of
730 YAZ 3.0.47 and later and so configure checks for that.
734 Metadata attribute 'skiparticle' also works for ICU based
735 normalization. (was only working for the non-ICU/ASCII before).
737 Command bytarget with argument settings=1 will show settings per
738 target.. This is to be able to verify correct settings and be able to
739 test that they are correct. The database settings array size is now
740 also stored.. Problems with database settings array is that if not
741 careful it will be too small (smaller than dictionary per-service
744 Make record list sorting stable by comparing mergekey for records if
745 relevance/title or other sorting criteria all match. This is merely to
746 ensure that our regressions tests works (reproducible output).
748 Relevance calculation changes: use a different denominator (length) for
749 per-field relevance scoring.. Instead of length of all ranked fields we
750 now use length of individual fields (as if they were individual "free"
751 text fields). This will ensure that documents with a long field with no
752 match (say description) will not "hurt" a title match.
754 Diagnostic member was not set on connection error. Fixed
758 Command search takes two optional parameters, startecs and maxrecs,
759 that specifies the start offset (0, 1, ...) and maximum number of records
760 to fetch for each target.
762 XSLTs + MARC maps are cached within a session so we don't re-parse
763 them over and over again. Even for a session with a single search
764 there's much to be gained because many targets use the same
767 The metadata attribute 'mergekey' now takes one of three values 'no',
768 'required', 'optional' . And the resulting mergekey from metadata
769 is now ordered in the same way as metadata in the service definition.
770 Older Pazpar2 version use the order in which metadata appeared in a
773 The search argument 'filter' now offers a new operator ~ which does a
774 substring match. The = operator works as before: string match for
775 anything but pz:id, or target match for pz:id.
777 New setting pz:recordfilter. The value of this setting takes the
778 form name[~value]. This setting makes Pazpar2 ignore all retrieved
779 records that do not have the metadata element name with value substring
782 Pazpar2 allows YAZ log level to be set (option -v).
786 For WS responses Pazpar2 creates XML header. Exception: raw record.
788 Setting XML files are now stored in etc/settings instead of etc. This
789 reflects the layout with the Debian package layout.
791 Settings may be posted for command=settings. The POSTed settings must
792 have root element 'settings' like regular setting files. In order to be
793 recognized, the POST request must use Content-Type=text/xml.
795 A service may be posted for command=init. This service will be used
796 during the session. The service may have its own target settings,
797 ICU config, timeout, etc. In order to be recognized, the POST request
798 must use Content-Type=text/xml.
800 Timeout values may be given per-service. That's element 'timeout'
801 which takes three attribute values (a subset may be given): 'session',
802 'z3950_operation', 'z3950_session'. Option -T is no longer supported
803 - used to specify session timeout.
805 Option -t tests the Pazpar2 configuration and returns exit code
806 (0=success, non-zero=failure). In previous version of Pazpar2, -t
807 specified local settings.
809 In version 1.2.0 the configuration file - after include processing -
810 was dumped to stdout. Now, the configuration is only dumped to the
811 yaz log file if option -d is given.
815 Configuration may now have multiple server areas. This means that a
816 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
817 yet supported - on a server basis. Configuration may also have multiple
818 services .. That is repeating service elements inside a server. Each
819 has an attribute 'id' which serves as service ID. This ID in turn may
820 be used in a Pazpar2 session, by specifying parameter service=ID for
821 command init. There can be at most one unnamed service inside a server
822 which can be referred to by not specifying an service ID for command
823 init (backwards compatible). In order to partition multiple servers and
824 services a new include directive has been added. This takes an attribute
825 'src' which specifies one or more sub-files. For example to include
826 service files, one might use:
827 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
828 It is the intention that that completely makes the settings directive
831 Fix problem where the record command would wait forever if there were
832 no targets to wait for (activeclients == 0).
836 One result set is created per session (last search) rather than for
837 each connection which happen to be shared (bug #3009).
839 marc21 stylesheets changed for efficiency.
843 Session timeout may be specified on the command-line as option -T.
845 Pazpar2 may now be operated in a no-merged mode for records.. All records
846 will be considered unique. This mode is enabled if no mergekey is
847 generated by the normalization stylesheet (pz:xslt).
849 Pazpar2 caches original records from each target and the 'record' command
850 with offset returns the original record if 'syntax' and 'esn' are NOT
851 specified. This speeds up retrieval of original records but also means
852 that Pazpar2 uses more memory. The cached records will be freed when the
853 session terminates or a new search is executed.
855 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
856 library part of YAZ is used.
858 Added SRU client support.
860 Automatically computes pz:nativesyntax if not provided. Works for XML and
863 --- 1.0.13 2008/11/24

879 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
883 Changed the JS library pz2.js to use POST for long URL (+ params).
885 Added installation instructions for Windows. Note: NT services is
886 NOT available until we make a new release of YAZ.
888 Preserve order of repeated metadata fields (they were reversed before).
890 More MARC21 information extracted for metadata.
894 Fixed bug #1162: HTML entities are not escaped properly.
896 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
900 Marc21 stylesheet updated to reflect multiple full text fields
904 Fixed bug in pz2.js WRT DOMElement attributes on IE.
906 Fixed bug 2100: Database wildcards not working
910 Added support for retrieval of records in binary.
912 Fixed bug 1794: Pazpar2 does not return valid XML.
914 Deal with ICU not returning sortkey (resulted in SEGV before).
918 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
919 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
921 Improved diagnostics when Pazpar2 HTTP decoding fails.
923 Pazpar2 requests may be POSTed as using Content-Type
924 application/x-www-form-urlencoded.
926 Pazpar2 honors LF in HTTP headers.
928 Handle targets that handle negative hit counts (should not happen, but it
933 ICU is used for tokenization and normalization of the following: mergekey,
934 sorting, relevance terms.
936 Debian package now enables ICU tokenization and normalization by default.
940 Exposed user setting values (i.e. non-pz: names) to the record systems in two
941 ways: Either as parameters to the normalization stylesheets (which would allow the
942 programmer to postprocess or use the values in any way) or after the normalization
943 step, in which case values are made part of the normalized record (and available for
944 sorting, termlists, display, or other interface-related use.
946 Implemented sorting by year.
948 Option -d dumps records to the current log file instead of stderr.
950 Fixes for compilation on cygwin.
952 Z39.50 client code uses pz:elements. pz:elements was recognized in
953 earlier Pazpar2 versions but it was not used for anything.
955 icu_chain_test is using fgets instead of getline - fixes compilation
958 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
959 query conversions fail (rather than _any_). This means targets that do
960 not support some fields are ignored in a search.
964 Improved handling of socket timeout for Z39.50 connections.
966 Misc documentation updates and spell fixes.
968 Debian package pazpar2 creates log rotate entry.
970 Debian package pazpar2-apache2 reloads Apache2.
972 jsdemo included in distribution. It illustrates the use of the js/pz2.js
