3 Route may be given for each port in frontend_net.
7 Documentation for zoom filter. Local target profiles may be specified.
13 First version with zoom filter.
17 Filter z3950_client may be configured to always send a close APDU
18 to backend target when connection/session is closed. This will only
19 happen if close APDU is not already sent. Enabled by configuration
20 for z3950_client (force_close).
22 Filter virt_db and multi: relay close APDU.
24 Filter virt_db and multi: relay init size parameters
25 preferredMessageSize and maximumRecordSize.
27 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
31 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
33 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
34 as determined by configure.
36 RPM: Release includes 'indexdata' name. Use indexdata in release name so
37 this package can be distinguished from other vendors.
41 Fix filter multi: relay idAuthentication parameters.
45 Add metaproxy-config for returning compiler flags, libraries.
49 Fix --with-boost=PREFIX .
53 session_shared: fix use of maintenance thread.
55 Introduce 'start' method for filters and routers. It gets called after
56 configure and after fork, but before processing. This changes API -
57 from libmetaproxy2 to libmetaproxy3.
61 session_shared: ensure backend session is closed if init rejected
64 z3950_client: fix NULL ptr reference that could occur if two clients
65 connected concurrently and if max-sockets was in effect.
69 Fix bug 3497 - Metaproxy unstable while stopping.
71 Fix bug 3495 - SEGV in SRU filter.
75 Filter multi throws diagnostic 'Present Out of Range' when
76 appropriate - rather than returning 0 records.
78 Filter virt_db: fix bad result reuse. Could happen if a result
79 was overriden and a backend did not supported named result sets.
83 Filter log: category access logs diagnostics even if searchStatus
84 or presentStatus is 'success'.
88 The SRU to Z39.50 filter does repeated Z39.50 present requests
89 to fetch all records. Needed when a Z39.50 server returns partial
90 results (due to message size limits).
94 Metaproxy now kills all child processes that are spawned by
95 modules (in case of fork, exec).
99 Debian package now installs /etc/metaproxy/metaproxy.xml which
100 includes all XML files /etc/metaproxy/filters-enabled .
101 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
105 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
106 development package to facilitate 3rd party Metaproxy modules.
108 --- 1.0.23 2010/01/04
110 Filter virt_db: Close backend filter session when Init rejected is received
111 from it (in which case it's not really closed yet). This will ensure we don't
112 run out of resources such as FDs in this case.
114 sru_z3950 filter: Accept any database (including those not listed).
116 --- 1.0.22 2009/12/03
118 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
119 later which means YAZ 3.0.47 or later.
121 --- 1.0.20 2009/11/19
123 For filter virt_db, the database is a glob pattern and the virtual
124 database sections are consulted in the order given.
126 --- 1.0.19 2009/07/08
128 For filter multi, the target (for routing) may be given as a glob-pattern.
130 More documentation for filters virt_db and multi.
132 Update schema to allow for no database in sru_z3950 filter.
134 --- 1.0.18 2009/06/30
136 Added limit filter to put sleep (penalty) for heavy use.
138 Filter frontend_net may be configured to limit the number of new connections
139 from same IP to some value (connect-max).
141 Fixed the load_balance filter.
143 --- 1.0.17 2009/06/16
145 Fix path for metaproxy executable for Debian init.d script.
147 --- 1.0.16 2009/06/10
149 SRU to Z39.50 filter honors x-username and x-password. If only
150 x-username is given that translates to open authentication (Z39.50v2). If
151 both x-username and x-password is present that translates to idPass
152 authentication (Z39.50v3).
154 New facility to change current working directory (-w).
156 Update to upstream skeleton of init.d script. Should fix bug #2619.
158 Filter session_shared now caches records (used to only cache connections
161 Filter session_shared now invalidates a Z39.50 session if a server
162 returns -1 hits. This facility was also part of yazproxy and gets around
163 a bug in Voyager-based Z39.50 servers.
165 --- 1.0.15 2008/11/18
167 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
169 --- 1.0.14 2008/06/09
171 Fixed the value of SRU record schema in searchRetrieve response. It was set
172 to a fixed value of "dc" before.
174 Serialize identical SRU requests. This is useful if HTTP client software
175 fires identical requests against metaproxy.
177 Allow Z39.50 target to be specified for SRU requests by using SRU extra
178 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
179 avoid static configuration. This facility is handled by the sru_z3950 module
180 and the z3950_client module.
182 Allow maximum number of sockets to be used for a Z39.50 client by the
183 use of SRU extra parameter x-max-sockets. This facility is handled by the
184 sru_z3950 module and the z3950_client module.
186 --- 1.0.13.1 2008/02/29
188 Simplified check for Boost libraries.
190 --- 1.0.13 2008/02/29
192 First Debian package.
194 The sru_z9350 filter now recognizes SRU parameter z-target as being
195 a ZURL of the form host/database .
197 Mergetype may be specified for filter 'multi'.
199 --- 1.0.12 2007/09/19
201 Fixed problem in Makefile WRT library specifictions. This could produce
202 linker errors (when they should not happen).
204 Fixed bug #1341: MetaProxy returning different results. Problem was that
205 fix-up of record database did not normalize the database name.
207 Documentation updates for Windows compilation.
209 --- 1.0.11 2007/06/14
211 Fixed problem with logfile being truncated.
213 --- 1.0.10 2007/05/23
215 Fixed bug #1136: Access rights not enforced.
217 Extension for log module. The log category 'access' logs more details.
218 New category 'user-access' added which is simlar to 'access' but adds
219 the Z39.50 user as for all entries in a session.
223 Added support for configurable default/force target/vhost for module Z39.50
228 Implemented filter, session_shared, which optimizes usage of Z39.50
229 sessions and result sets.
231 New filter, record_transform, which converts MARC/XML records.
233 New filter, sru_z3950, which converts SRU to Z39.50 packages.
235 New filter, load_balance, in development.
237 New filter, zeerex_xplain.
239 XML framework for config files started.
241 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
242 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
243 XML config files are checked against RNG and XML Schema's.
245 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
246 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
247 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
248 explain record to YAZ CQL-to-PQF text config file.
252 Added 'timeout' setting for filter frontend_net which specifies the number
253 of seconds a session is idle before it is closed. Default timeout is
258 Database name in records returned set for virt_db/multi filters.
260 Filter session_shared now functional.
262 Log filter can be configured to write to a given file using 'filename'
263 element. Also information category can be specified with 'category'. If
264 filename is omitted, the log filter writes to stdout. See etc/config5.xml
269 Fixed compilation on Windows.
273 Added documentation for the hidenavailable option for the multi filter.
277 Fixed bug #573: Hide errors for individual servers. If the element
278 'hideunavailable' is given in the configuration, individual servers
279 being unavailable are hidden (unless all are unavailable).
281 Fixed bug #574: Database names are recognised case-sensitively.
283 Fixed bug #567: Fix up database name in Name-Plus-Record.
285 Fixed bug #568: Update win/makefile for VS 2005.
287 Fixed bug #569: Some options throws unknown exception.
291 More information about virtual hosts. The 'etc' directory is part of the
296 Build instructions for Windows. NMake makefile part of distribution tar.
302 Filters functional: auth_simple, backend_test, frontend_net, http_file,
303 log, multi, query_rewrite, template, virt_db, z3950_client.
305 Filters in development: session_shared.
307 Pseudo-filters: template, dl
