3 For WS responses Pazpar2 creates XML header. Exception: raw record.
5 Setting XML files are now stored in etc/settings instead of etc. This
6 reflects the layout with the Debian package layout.
8 Settings may be posted for command=settings. The POSTed settings must
9 have root element 'settings' like regular setting files. In order to be
10 recognized, the POST request must use Content-Type=text/xml.
12 A service may be posted for command=init. This service will be used
13 during the session. The service may have its own target settings,
14 ICU config, timeout, etc. In order to be recognized, the POST request
15 must use Content-Type=text/xml.
17 Timeout values may be given per-service. That's element 'timeout'
18 which takes three attribute values (a subset may be given): 'session',
19 'z3950_operation', 'z3950_session'. Option -T is no longer supported
20 - used to specify session timeout.
22 Option -t tests the Pazpar2 configuration and returns exit code
23 (0=success, non-zero=failure). In previous version of Pazpar2, -t
24 specified local settings.
26 In version 1.2.0 the configuration file - after include processing -
27 was dumped to stdout. Now, the configuration is only dumped to the
28 yaz log file if option -d is given.
32 Configuration may now have multiple server areas. This means that a
33 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
34 yet supported - on a server basis. Configuration may also have multiple
35 services .. That is repeating service elements inside a server. Each
36 has an attribute 'id' which serves as service ID. This ID in turn may
37 be used in a Pazpar2 session, by specifying parameter service=ID for
38 command init. There can be at most one unnamed service inside a server
39 which can be referred to by not specifying an service ID for command
40 init (backwards compatible). In order to partition multiple servers and
41 services a new include directive has been added. This takes an attribute
42 'src' which specifies one or more sub-files. For example to include
43 service files, one might use:
44 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
45 It is the intention that that completely makes the settings directive
48 Fix problem where the record command would wait forever if there were
49 no targets to wait for (activeclients == 0).
53 One result set is created per session (last search) rather than for
54 each connection which happen to be shared (bug #3009).
56 marc21 stylesheets changed for efficiency.
60 Session timeout may be specified on the command-line as option -T.
62 Pazpar2 may now be operated in a no-merged mode for records.. All records
63 will be considered unique. This mode is enabled if no mergekey is
64 generated by the normalization stylesheet (pz:xslt).
66 Pazpar2 caches original records from each target and the 'record' command
67 with offset returns the original record if 'syntax' and 'esn' are NOT
68 specified. This speeds up retrieval of original records but also means
69 that Pazpar2 uses more memory. The cached records will be freed when the
70 session terminates or a new search is executed.
72 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
73 library part of YAZ is used.
75 Added SRU client support.
77 Automatically computes pz:nativesyntax if not provided. Works for XML and
82 Command bytarget returns name of target (if defined).
86 Fixed bug #2021.. location now holds all brief elements.
90 Fixed check for application/x-www-form-urlencoded parameters.
94 Fixes for IE in pz2.js.
96 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
100 Changed the JS library pz2.js to use POST for long URL (+ params).
102 Added installation instructions for Windows. Note: NT services is
103 NOT available until we make a new release of YAZ.
105 Preserve order of repeated metadata fields (they were reversed before).
107 More MARC21 information extracted for metadata.
111 Fixed bug #1162: HTML entities are not escaped properly.
113 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
117 Marc21 stylesheet updated to reflect multiple full text fields
121 Fixed bug in pz2.js WRT DOMElement attributes on IE.
123 Fixed bug 2100: Database wildcards not working
127 Added support for retrieval of records in binary.
129 Fixed bug 1794: Pazpar2 does not return valid XML.
131 Deal with ICU not returning sortkey (resulted in SEGV before).
135 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
136 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
138 Improved diagnostics when Pazpar2 HTTP decoding fails.
140 Pazpar2 requests may be POSTed as using Content-Type
141 application/x-www-form-urlencoded.
143 Pazpar2 honors LF in HTTP headers.
145 Handle targets that handle negative hit counts (should not happen, but it
150 ICU is used for tokenization and normalization of the following: mergekey,
151 sorting, relevance terms.
153 Debian package now enables ICU tokenization and normalization by default.
157 Exposed user setting values (i.e. non-pz: names) to the record systems in two
158 ways: Either as parameters to the normalization stylesheets (which would allow the
159 programmer to postprocess or use the values in any way) or after the normalization
160 step, in which case values are made part of the normalized record (and available for
161 sorting, termlists, display, or other interface-related use.
163 Implemented sorting by year.
165 Option -d dumps records to the current log file instead of stderr.
167 Fixes for compilation on cygwin.
169 Z39.50 client code uses pz:elements. pz:elements was recognized in
170 earlier Pazpar2 versions but it was not used for anything.
172 icu_chain_test is using fgets instead of getline - fixes compilation
175 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
176 query conversions fail (rather than _any_). This means targets that do
177 not support some fields are ignored in a search.
181 Improved handling of socket timeout for Z39.50 connections.
183 Misc documentation updates and spell fixes.
185 Debian package pazpar2 creates log rotate entry.
187 Debian package pazpar2-apache2 reloads Apache2.
189 jsdemo included in distribution. It illustrates the use of the js/pz2.js
194 First public release.
