1 The metadata attribute 'mergekey' now takes one of three values 'no',
2 'required', 'optional' . And the resulting mergekey from metadata
3 is now ordered in the same way as metadata in the service definition.
4 Older Pazpar2 version use the order in which metadata appeared in a
7 Pazpar2 allows YAZ log level to be set (option -v).
11 For WS responses Pazpar2 creates XML header. Exception: raw record.
13 Setting XML files are now stored in etc/settings instead of etc. This
14 reflects the layout with the Debian package layout.
16 Settings may be posted for command=settings. The POSTed settings must
17 have root element 'settings' like regular setting files. In order to be
18 recognized, the POST request must use Content-Type=text/xml.
20 A service may be posted for command=init. This service will be used
21 during the session. The service may have its own target settings,
22 ICU config, timeout, etc. In order to be recognized, the POST request
23 must use Content-Type=text/xml.
25 Timeout values may be given per-service. That's element 'timeout'
26 which takes three attribute values (a subset may be given): 'session',
27 'z3950_operation', 'z3950_session'. Option -T is no longer supported
28 - used to specify session timeout.
30 Option -t tests the Pazpar2 configuration and returns exit code
31 (0=success, non-zero=failure). In previous version of Pazpar2, -t
32 specified local settings.
34 In version 1.2.0 the configuration file - after include processing -
35 was dumped to stdout. Now, the configuration is only dumped to the
36 yaz log file if option -d is given.
40 Configuration may now have multiple server areas. This means that a
41 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
42 yet supported - on a server basis. Configuration may also have multiple
43 services .. That is repeating service elements inside a server. Each
44 has an attribute 'id' which serves as service ID. This ID in turn may
45 be used in a Pazpar2 session, by specifying parameter service=ID for
46 command init. There can be at most one unnamed service inside a server
47 which can be referred to by not specifying an service ID for command
48 init (backwards compatible). In order to partition multiple servers and
49 services a new include directive has been added. This takes an attribute
50 'src' which specifies one or more sub-files. For example to include
51 service files, one might use:
52 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
53 It is the intention that that completely makes the settings directive
56 Fix problem where the record command would wait forever if there were
57 no targets to wait for (activeclients == 0).
61 One result set is created per session (last search) rather than for
62 each connection which happen to be shared (bug #3009).
64 marc21 stylesheets changed for efficiency.
68 Session timeout may be specified on the command-line as option -T.
70 Pazpar2 may now be operated in a no-merged mode for records.. All records
71 will be considered unique. This mode is enabled if no mergekey is
72 generated by the normalization stylesheet (pz:xslt).
74 Pazpar2 caches original records from each target and the 'record' command
75 with offset returns the original record if 'syntax' and 'esn' are NOT
76 specified. This speeds up retrieval of original records but also means
77 that Pazpar2 uses more memory. The cached records will be freed when the
78 session terminates or a new search is executed.
80 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
81 library part of YAZ is used.
83 Added SRU client support.
85 Automatically computes pz:nativesyntax if not provided. Works for XML and
90 Command bytarget returns name of target (if defined).
94 Fixed bug #2021.. location now holds all brief elements.
98 Fixed check for application/x-www-form-urlencoded parameters.
100 --- 1.0.10 2008/10/14
102 Fixes for IE in pz2.js.
104 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
108 Changed the JS library pz2.js to use POST for long URL (+ params).
110 Added installation instructions for Windows. Note: NT services is
111 NOT available until we make a new release of YAZ.
113 Preserve order of repeated metadata fields (they were reversed before).
115 More MARC21 information extracted for metadata.
119 Fixed bug #1162: HTML entities are not escaped properly.
121 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
125 Marc21 stylesheet updated to reflect multiple full text fields
129 Fixed bug in pz2.js WRT DOMElement attributes on IE.
131 Fixed bug 2100: Database wildcards not working
135 Added support for retrieval of records in binary.
137 Fixed bug 1794: Pazpar2 does not return valid XML.
139 Deal with ICU not returning sortkey (resulted in SEGV before).
143 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
144 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
146 Improved diagnostics when Pazpar2 HTTP decoding fails.
148 Pazpar2 requests may be POSTed as using Content-Type
149 application/x-www-form-urlencoded.
151 Pazpar2 honors LF in HTTP headers.
153 Handle targets that handle negative hit counts (should not happen, but it
158 ICU is used for tokenization and normalization of the following: mergekey,
159 sorting, relevance terms.
161 Debian package now enables ICU tokenization and normalization by default.
165 Exposed user setting values (i.e. non-pz: names) to the record systems in two
166 ways: Either as parameters to the normalization stylesheets (which would allow the
167 programmer to postprocess or use the values in any way) or after the normalization
168 step, in which case values are made part of the normalized record (and available for
169 sorting, termlists, display, or other interface-related use.
171 Implemented sorting by year.
173 Option -d dumps records to the current log file instead of stderr.
175 Fixes for compilation on cygwin.
177 Z39.50 client code uses pz:elements. pz:elements was recognized in
178 earlier Pazpar2 versions but it was not used for anything.
180 icu_chain_test is using fgets instead of getline - fixes compilation
183 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
184 query conversions fail (rather than _any_). This means targets that do
185 not support some fields are ignored in a search.
189 Improved handling of socket timeout for Z39.50 connections.
191 Misc documentation updates and spell fixes.
193 Debian package pazpar2 creates log rotate entry.
195 Debian package pazpar2-apache2 reloads Apache2.
197 jsdemo included in distribution. It illustrates the use of the js/pz2.js
202 First public release.
