1 Filter virt_db and multi relays close APDU.
3 Filter virt_db and multi: relay init size parameters
4 preferredMessageSize and maximumRecordSize.
6 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
10 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
12 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
13 as determined by configure.
15 RPM: Release includes 'indexdata' name. Use indexdata in release name so
16 this package can be distinguished from other vendors.
20 Fix filter multi: relay idAuthentication parameters.
24 Add metaproxy-config for returning compiler flags, libraries.
28 Fix --with-boost=PREFIX .
32 session_shared: fix use of maintenance thread.
34 Introduce 'start' method for filters and routers. It gets called after
35 configure and after fork, but before processing. This changes API -
36 from libmetaproxy2 to libmetaproxy3.
40 session_shared: ensure backend session is closed if init rejected
43 z3950_client: fix NULL ptr reference that could occur if two clients
44 connected concurrently and if max-sockets was in effect.
48 Fix bug 3497 - Metaproxy unstable while stopping.
50 Fix bug 3495 - SEGV in SRU filter.
54 Filter multi throws diagnostic 'Present Out of Range' when
55 appropriate - rather than returning 0 records.
57 Filter virt_db: fix bad result reuse. Could happen if a result
58 was overriden and a backend did not supported named result sets.
62 Filter log: category access logs diagnostics even if searchStatus
63 or presentStatus is 'success'.
67 The SRU to Z39.50 filter does repeated Z39.50 present requests
68 to fetch all records. Needed when a Z39.50 server returns partial
69 results (due to message size limits).
73 Metaproxy now kills all child processes that are spawned by
74 modules (in case of fork, exec).
78 Debian package now installs /etc/metaproxy/metaproxy.xml which
79 includes all XML files /etc/metaproxy/filters-enabled .
80 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
84 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
85 development package to facilitate 3rd party Metaproxy modules.
89 Filter virt_db: Close backend filter session when Init rejected is received
90 from it (in which case it's not really closed yet). This will ensure we don't
91 run out of resources such as FDs in this case.
93 sru_z3950 filter: Accept any database (including those not listed).
97 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
98 later which means YAZ 3.0.47 or later.
100 --- 1.0.20 2009/11/19
102 For filter virt_db, the database is a glob pattern and the virtual
103 database sections are consulted in the order given.
105 --- 1.0.19 2009/07/08
107 For filter multi, the target (for routing) may be given as a glob-pattern.
109 More documentation for filters virt_db and multi.
111 Update schema to allow for no database in sru_z3950 filter.
113 --- 1.0.18 2009/06/30
115 Added limit filter to put sleep (penalty) for heavy use.
117 Filter frontend_net may be configured to limit the number of new connections
118 from same IP to some value (connect-max).
120 Fixed the load_balance filter.
122 --- 1.0.17 2009/06/16
124 Fix path for metaproxy executable for Debian init.d script.
126 --- 1.0.16 2009/06/10
128 SRU to Z39.50 filter honors x-username and x-password. If only
129 x-username is given that translates to open authentication (Z39.50v2). If
130 both x-username and x-password is present that translates to idPass
131 authentication (Z39.50v3).
133 New facility to change current working directory (-w).
135 Update to upstream skeleton of init.d script. Should fix bug #2619.
137 Filter session_shared now caches records (used to only cache connections
140 Filter session_shared now invalidates a Z39.50 session if a server
141 returns -1 hits. This facility was also part of yazproxy and gets around
142 a bug in Voyager-based Z39.50 servers.
144 --- 1.0.15 2008/11/18
146 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
148 --- 1.0.14 2008/06/09
150 Fixed the value of SRU record schema in searchRetrieve response. It was set
151 to a fixed value of "dc" before.
153 Serialize identical SRU requests. This is useful if HTTP client software
154 fires identical requests against metaproxy.
156 Allow Z39.50 target to be specified for SRU requests by using SRU extra
157 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
158 avoid static configuration. This facility is handled by the sru_z3950 module
159 and the z3950_client module.
161 Allow maximum number of sockets to be used for a Z39.50 client by the
162 use of SRU extra parameter x-max-sockets. This facility is handled by the
163 sru_z3950 module and the z3950_client module.
165 --- 1.0.13.1 2008/02/29
167 Simplified check for Boost libraries.
169 --- 1.0.13 2008/02/29
171 First Debian package.
173 The sru_z9350 filter now recognizes SRU parameter z-target as being
174 a ZURL of the form host/database .
176 Mergetype may be specified for filter 'multi'.
178 --- 1.0.12 2007/09/19
180 Fixed problem in Makefile WRT library specifictions. This could produce
181 linker errors (when they should not happen).
183 Fixed bug #1341: MetaProxy returning different results. Problem was that
184 fix-up of record database did not normalize the database name.
186 Documentation updates for Windows compilation.
188 --- 1.0.11 2007/06/14
190 Fixed problem with logfile being truncated.
192 --- 1.0.10 2007/05/23
194 Fixed bug #1136: Access rights not enforced.
196 Extension for log module. The log category 'access' logs more details.
197 New category 'user-access' added which is simlar to 'access' but adds
198 the Z39.50 user as for all entries in a session.
202 Added support for configurable default/force target/vhost for module Z39.50
207 Implemented filter, session_shared, which optimizes usage of Z39.50
208 sessions and result sets.
210 New filter, record_transform, which converts MARC/XML records.
212 New filter, sru_z3950, which converts SRU to Z39.50 packages.
214 New filter, load_balance, in development.
216 New filter, zeerex_xplain.
218 XML framework for config files started.
220 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
221 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
222 XML config files are checked against RNG and XML Schema's.
224 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
225 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
226 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
227 explain record to YAZ CQL-to-PQF text config file.
231 Added 'timeout' setting for filter frontend_net which specifies the number
232 of seconds a session is idle before it is closed. Default timeout is
237 Database name in records returned set for virt_db/multi filters.
239 Filter session_shared now functional.
241 Log filter can be configured to write to a given file using 'filename'
242 element. Also information category can be specified with 'category'. If
243 filename is omitted, the log filter writes to stdout. See etc/config5.xml
248 Fixed compilation on Windows.
252 Added documentation for the hidenavailable option for the multi filter.
256 Fixed bug #573: Hide errors for individual servers. If the element
257 'hideunavailable' is given in the configuration, individual servers
258 being unavailable are hidden (unless all are unavailable).
260 Fixed bug #574: Database names are recognised case-sensitively.
262 Fixed bug #567: Fix up database name in Name-Plus-Record.
264 Fixed bug #568: Update win/makefile for VS 2005.
266 Fixed bug #569: Some options throws unknown exception.
270 More information about virtual hosts. The 'etc' directory is part of the
275 Build instructions for Windows. NMake makefile part of distribution tar.
281 Filters functional: auth_simple, backend_test, frontend_net, http_file,
282 log, multi, query_rewrite, template, virt_db, z3950_client.
284 Filters in development: session_shared.
286 Pseudo-filters: template, dl
