Enabled by element threads in +the configuration. See pazpar2_conf for details. + +New setting setting: pz:max_connections. Setting pz:max_connections is +a limit of number of sockets to a host. When this limit is reached, +Pazpar2 will wait up to 5 seconds for a connection to becomes available. +The client will be marked Client_Error when it can not be searched +(other clients in a session may work). If pz:max_connections is not set +for a target, a value of 30 will be used. Note: the pz:max_connections +will only work in threaded mode. + +pz2.js: JSON support for show. + +Debian package: Enable default service, default.xml, before starting +Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled. + +--- 1.3.0 2010/01/25 + +Debian version depends on on libyaz4. Note that Pazpar2 will still +compile from source with YAZ 3. + +Split services into separate files. The example configuration file +pazpar2.cfg.dist now includes a default service default.xml (part of +etc). And default.xml includes settings/edu.xml. The default.xml file, +not to be confused with settings/defaults.xml, is a template for jsdemo +and other services. The Debian package installs /etc/pazpar2/server.xml +which is now the main pazpar2 configuration (used to be called pazpar2.cfg). +server.xml includes services from /etc/pazpar2/services-enabled/*.xml . +The default.xml (from etc) is installed in /etc/pazpar2/services-available +and a symlink to it is created from services-enabled. The default.xml +service is unnamed and, thus, will be used by jsdemo and test1. + +New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The +new setting pz:negotiation_charset specifies character set for Z39.50 Init. + +--- 1.2.4 2010/01/15 + +Support for additional fields in cf.xsl and pazpar2.conf.dist: +publisher, available, due, location (=locallocation), callno +(=callnumber), thumburl and score. + +Describe pz:xslt and the auto setting. + +Move mergekey definition away from the normalization stylesheets and +define a mergekey common for all target types in pazpar2.cfg. + +Code update: Use the Odr_int type for hit counts. This is part of +YAZ 3.0.47 and later and so configure checks for that. + +--- 1.2.3 2009/11/24 + +Metadata attribute 'skiparticle' also works for ICU based +normalization. (was only working for the non-ICU/ASCII before). + +Command bytarget with argument settings=1 will show settings per +target.. This is to be able to verify correct settings and be able to +test that they are correct. The database settings array size is now +also stored.. Problems with database settings array is that if not +careful it will be too small (smaller than dictionary per-service +in settings). + +Make record list sorting stable by comparing mergekey for records if +relevance/title or other sorting criteria all match. This is merely to +ensure that our regressions tests works (reproducible output). + +Relevance calculation changes: use a different denominator (length) for +per-field relevance scoring.. Instead of length of all ranked fields we +now use length of individual fields (as if they were individual "free" +text fields). This will ensure that documents with a long field with no +match (say description) will not "hurt" a title match. + +Diagnostic member was not set on connection error. Fixed + +--- 1.2.2 2009/10/13 + +Command search takes two optional parameters, startecs and maxrecs, +that specifies the start offset (0, 1, ...) and maximum number of records +to fetch for each target. + +XSLTs + MARC maps are cached within a session so we don't re-parse +them over and over again. Even for a session with a single search +there's much to be gained because many targets use the same +transformation. + +The metadata attribute 'mergekey' now takes one of three values 'no', +'required', 'optional' . And the resulting mergekey from metadata +is now ordered in the same way as metadata in the service definition. +Older Pazpar2 version use the order in which metadata appeared in a +record instance. + +The search argument 'filter' now offers a new operator ~ which does a +substring match. The = operator works as before: string match for +anything but pz:id, or target match for pz:id. + +New setting pz:recordfilter. The value of this setting takes the +form name[~value]. This setting makes Pazpar2 ignore all retrieved +records that do not have the metadata element name with value substring +(if given). + +Pazpar2 allows YAZ log level to be set (option -v). + +--- 1.2.1 2009/10/05 + +For WS responses Pazpar2 creates XML header. Exception: raw record. + +Setting XML files are now stored in etc/settings instead of etc. This +reflects the layout with the Debian package layout. + +Settings may be posted for command=settings. The POSTed settings must +have root element 'settings' like regular setting files. In order to be +recognized, the POST request must use Content-Type=text/xml. + +A service may be posted for command=init. This service will be used +during the session. The service may have its own target settings, +ICU config, timeout, etc. In order to be recognized, the POST request +must use Content-Type=text/xml. + +Timeout values may be given per-service. That's element 'timeout' +which takes three attribute values (a subset may be given): 'session', +'z3950_operation', 'z3950_session'. Option -T is no longer supported +- used to specify session timeout. + +Option -t tests the Pazpar2 configuration and returns exit code +(0=success, non-zero=failure). In previous version of Pazpar2, -t +specified local settings. + +In version 1.2.0 the configuration file - after include processing - +was dumped to stdout. Now, the configuration is only dumped to the +yaz log file if option -d is given. + +--- 1.2.0 2009/09/10 + +Configuration may now have multiple server areas. This means that a +Pazpar2 instance may listen on multiple ports. Virtual hosting is not +yet supported - on a server basis. Configuration may also have multiple +services .. That is repeating service elements inside a server. Each +has an attribute 'id' which serves as service ID. This ID in turn may +be used in a Pazpar2 session, by specifying parameter service=ID for +command init. There can be at most one unnamed service inside a server +which can be referred to by not specifying an service ID for command +init (backwards compatible). In order to partition multiple servers and +services a new include directive has been added. This takes an attribute +'src' which specifies one or more sub-files. For example to include +service files, one might use: + .. .. . +It is the intention that that completely makes the settings directive +redundant. + +Fix problem where the record command would wait forever if there were +no targets to wait for (activeclients == 0). + +--- 1.1.1 2009/08/28 + +One result set is created per session (last search) rather than for +each connection which happen to be shared (bug #3009). + +marc21 stylesheets changed for efficiency. + +--- 1.1.0 2009/08/19 + +Session timeout may be specified on the command-line as option -T. + +Pazpar2 may now be operated in a no-merged mode for records.. All records +will be considered unique. This mode is enabled if no mergekey is +generated by the normalization stylesheet (pz:xslt). + +Pazpar2 caches original records from each target and the 'record' command +with offset returns the original record if 'syntax' and 'esn' are NOT +specified. This speeds up retrieval of original records but also means +that Pazpar2 uses more memory. The cached records will be freed when the +session terminates or a new search is executed. + +Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper +library part of YAZ is used. + +Added SRU client support. + +Automatically computes pz:nativesyntax if not provided. Works for XML and +MARC. --- 1.0.13 2008/11/24
