2 Filter log: category access logs diagnostics even if searchStatus
3 or presentStatus is 'success'.
7 The SRU to Z39.50 filter does repeated Z39.50 present requests
8 to fetch all records. Needed when a Z39.50 server returns partial
9 results (due to message size limits).
13 Metaproxy now kills all child processes that are spawned by
14 modules (in case of fork, exec).
18 Debian package now installs /etc/metaproxy/metaproxy.xml which
19 includes all XML files /etc/metaproxy/filters-enabled .
20 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
24 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
25 development package to facilitate 3rd party Metaproxy modules.
29 Filter virt_db: Close backend filter session when Init rejected is received
30 from it (in which case it's not really closed yet). This will ensure we don't
31 run out of resources such as FDs in this case.
33 sru_z3950 filter: Accept any database (including those not listed).
37 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
38 later which means YAZ 3.0.47 or later.
42 For filter virt_db, the database is a glob pattern and the virtual
43 database sections are consulted in the order given.
47 For filter multi, the target (for routing) may be given as a glob-pattern.
49 More documentation for filters virt_db and multi.
51 Update schema to allow for no database in sru_z3950 filter.
55 Added limit filter to put sleep (penalty) for heavy use.
57 Filter frontend_net may be configured to limit the number of new connections
58 from same IP to some value (connect-max).
60 Fixed the load_balance filter.
64 Fix path for metaproxy executable for Debian init.d script.
68 SRU to Z39.50 filter honors x-username and x-password. If only
69 x-username is given that translates to open authentication (Z39.50v2). If
70 both x-username and x-password is present that translates to idPass
71 authentication (Z39.50v3).
73 New facility to change current working directory (-w).
75 Update to upstream skeleton of init.d script. Should fix bug #2619.
77 Filter session_shared now caches records (used to only cache connections
80 Filter session_shared now invalidates a Z39.50 session if a server
81 returns -1 hits. This facility was also part of yazproxy and gets around
82 a bug in Voyager-based Z39.50 servers.
86 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
90 Fixed the value of SRU record schema in searchRetrieve response. It was set
91 to a fixed value of "dc" before.
93 Serialize identical SRU requests. This is useful if HTTP client software
94 fires identical requests against metaproxy.
96 Allow Z39.50 target to be specified for SRU requests by using SRU extra
97 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
98 avoid static configuration. This facility is handled by the sru_z3950 module
99 and the z3950_client module.
101 Allow maximum number of sockets to be used for a Z39.50 client by the
102 use of SRU extra parameter x-max-sockets. This facility is handled by the
103 sru_z3950 module and the z3950_client module.
105 --- 1.0.13.1 2008/02/29
107 Simplified check for Boost libraries.
109 --- 1.0.13 2008/02/29
111 First Debian package.
113 The sru_z9350 filter now recognizes SRU parameter z-target as being
114 a ZURL of the form host/database .
116 Mergetype may be specified for filter 'multi'.
118 --- 1.0.12 2007/09/19
120 Fixed problem in Makefile WRT library specifictions. This could produce
121 linker errors (when they should not happen).
123 Fixed bug #1341: MetaProxy returning different results. Problem was that
124 fix-up of record database did not normalize the database name.
126 Documentation updates for Windows compilation.
128 --- 1.0.11 2007/06/14
130 Fixed problem with logfile being truncated.
132 --- 1.0.10 2007/05/23
134 Fixed bug #1136: Access rights not enforced.
136 Extension for log module. The log category 'access' logs more details.
137 New category 'user-access' added which is simlar to 'access' but adds
138 the Z39.50 user as for all entries in a session.
142 Added support for configurable default/force target/vhost for module Z39.50
147 Implemented filter, session_shared, which optimizes usage of Z39.50
148 sessions and result sets.
150 New filter, record_transform, which converts MARC/XML records.
152 New filter, sru_z3950, which converts SRU to Z39.50 packages.
154 New filter, load_balance, in development.
156 New filter, zeerex_xplain.
158 XML framework for config files started.
160 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
161 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
162 XML config files are checked against RNG and XML Schema's.
164 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
165 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
166 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
167 explain record to YAZ CQL-to-PQF text config file.
171 Added 'timeout' setting for filter frontend_net which specifies the number
172 of seconds a session is idle before it is closed. Default timeout is
177 Database name in records returned set for virt_db/multi filters.
179 Filter session_shared now functional.
181 Log filter can be configured to write to a given file using 'filename'
182 element. Also information category can be specified with 'category'. If
183 filename is omitted, the log filter writes to stdout. See etc/config5.xml
188 Fixed compilation on Windows.
192 Added documentation for the hidenavailable option for the multi filter.
196 Fixed bug #573: Hide errors for individual servers. If the element
197 'hideunavailable' is given in the configuration, individual servers
198 being unavailable are hidden (unless all are unavailable).
200 Fixed bug #574: Database names are recognised case-sensitively.
202 Fixed bug #567: Fix up database name in Name-Plus-Record.
204 Fixed bug #568: Update win/makefile for VS 2005.
206 Fixed bug #569: Some options throws unknown exception.
210 More information about virtual hosts. The 'etc' directory is part of the
215 Build instructions for Windows. NMake makefile part of distribution tar.
221 Filters functional: auth_simple, backend_test, frontend_net, http_file,
222 log, multi, query_rewrite, template, virt_db, z3950_client.
224 Filters in development: session_shared.
