3 Filter log: category access logs diagnostics even if searchStatus
4 or presentStatus is 'success'.
8 The SRU to Z39.50 filter does repeated Z39.50 present requests
9 to fetch all records. Needed when a Z39.50 server returns partial
10 results (due to message size limits).
14 Metaproxy now kills all child processes that are spawned by
15 modules (in case of fork, exec).
19 Debian package now installs /etc/metaproxy/metaproxy.xml which
20 includes all XML files /etc/metaproxy/filters-enabled .
21 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
25 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
26 development package to facilitate 3rd party Metaproxy modules.
30 Filter virt_db: Close backend filter session when Init rejected is received
31 from it (in which case it's not really closed yet). This will ensure we don't
32 run out of resources such as FDs in this case.
34 sru_z3950 filter: Accept any database (including those not listed).
38 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
39 later which means YAZ 3.0.47 or later.
43 For filter virt_db, the database is a glob pattern and the virtual
44 database sections are consulted in the order given.
48 For filter multi, the target (for routing) may be given as a glob-pattern.
50 More documentation for filters virt_db and multi.
52 Update schema to allow for no database in sru_z3950 filter.
56 Added limit filter to put sleep (penalty) for heavy use.
58 Filter frontend_net may be configured to limit the number of new connections
59 from same IP to some value (connect-max).
61 Fixed the load_balance filter.
65 Fix path for metaproxy executable for Debian init.d script.
69 SRU to Z39.50 filter honors x-username and x-password. If only
70 x-username is given that translates to open authentication (Z39.50v2). If
71 both x-username and x-password is present that translates to idPass
72 authentication (Z39.50v3).
74 New facility to change current working directory (-w).
76 Update to upstream skeleton of init.d script. Should fix bug #2619.
78 Filter session_shared now caches records (used to only cache connections
81 Filter session_shared now invalidates a Z39.50 session if a server
82 returns -1 hits. This facility was also part of yazproxy and gets around
83 a bug in Voyager-based Z39.50 servers.
87 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
91 Fixed the value of SRU record schema in searchRetrieve response. It was set
92 to a fixed value of "dc" before.
94 Serialize identical SRU requests. This is useful if HTTP client software
95 fires identical requests against metaproxy.
97 Allow Z39.50 target to be specified for SRU requests by using SRU extra
98 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
99 avoid static configuration. This facility is handled by the sru_z3950 module
100 and the z3950_client module.
102 Allow maximum number of sockets to be used for a Z39.50 client by the
103 use of SRU extra parameter x-max-sockets. This facility is handled by the
104 sru_z3950 module and the z3950_client module.
106 --- 1.0.13.1 2008/02/29
108 Simplified check for Boost libraries.
110 --- 1.0.13 2008/02/29
112 First Debian package.
114 The sru_z9350 filter now recognizes SRU parameter z-target as being
115 a ZURL of the form host/database .
117 Mergetype may be specified for filter 'multi'.
119 --- 1.0.12 2007/09/19
121 Fixed problem in Makefile WRT library specifictions. This could produce
122 linker errors (when they should not happen).
124 Fixed bug #1341: MetaProxy returning different results. Problem was that
125 fix-up of record database did not normalize the database name.
127 Documentation updates for Windows compilation.
129 --- 1.0.11 2007/06/14
131 Fixed problem with logfile being truncated.
133 --- 1.0.10 2007/05/23
135 Fixed bug #1136: Access rights not enforced.
137 Extension for log module. The log category 'access' logs more details.
138 New category 'user-access' added which is simlar to 'access' but adds
139 the Z39.50 user as for all entries in a session.
143 Added support for configurable default/force target/vhost for module Z39.50
148 Implemented filter, session_shared, which optimizes usage of Z39.50
149 sessions and result sets.
151 New filter, record_transform, which converts MARC/XML records.
153 New filter, sru_z3950, which converts SRU to Z39.50 packages.
155 New filter, load_balance, in development.
157 New filter, zeerex_xplain.
159 XML framework for config files started.
161 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
162 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
163 XML config files are checked against RNG and XML Schema's.
165 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
166 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
167 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
168 explain record to YAZ CQL-to-PQF text config file.
172 Added 'timeout' setting for filter frontend_net which specifies the number
173 of seconds a session is idle before it is closed. Default timeout is
178 Database name in records returned set for virt_db/multi filters.
180 Filter session_shared now functional.
182 Log filter can be configured to write to a given file using 'filename'
183 element. Also information category can be specified with 'category'. If
184 filename is omitted, the log filter writes to stdout. See etc/config5.xml
189 Fixed compilation on Windows.
193 Added documentation for the hidenavailable option for the multi filter.
197 Fixed bug #573: Hide errors for individual servers. If the element
198 'hideunavailable' is given in the configuration, individual servers
199 being unavailable are hidden (unless all are unavailable).
201 Fixed bug #574: Database names are recognised case-sensitively.
203 Fixed bug #567: Fix up database name in Name-Plus-Record.
205 Fixed bug #568: Update win/makefile for VS 2005.
207 Fixed bug #569: Some options throws unknown exception.
211 More information about virtual hosts. The 'etc' directory is part of the
216 Build instructions for Windows. NMake makefile part of distribution tar.
222 Filters functional: auth_simple, backend_test, frontend_net, http_file,
223 log, multi, query_rewrite, template, virt_db, z3950_client.
225 Filters in development: session_shared.
