3 Documentation for zoom filter. Local target profiles may be specified.
9 First version with zoom filter.
13 Filter z3950_client may be configured to always send a close APDU
14 to backend target when connection/session is closed. This will only
15 happen if close APDU is not already sent. Enabled by configuration
16 for z3950_client (force_close).
18 Filter virt_db and multi: relay close APDU.
20 Filter virt_db and multi: relay init size parameters
21 preferredMessageSize and maximumRecordSize.
23 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
27 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
29 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
30 as determined by configure.
32 RPM: Release includes 'indexdata' name. Use indexdata in release name so
33 this package can be distinguished from other vendors.
37 Fix filter multi: relay idAuthentication parameters.
41 Add metaproxy-config for returning compiler flags, libraries.
45 Fix --with-boost=PREFIX .
49 session_shared: fix use of maintenance thread.
51 Introduce 'start' method for filters and routers. It gets called after
52 configure and after fork, but before processing. This changes API -
53 from libmetaproxy2 to libmetaproxy3.
57 session_shared: ensure backend session is closed if init rejected
60 z3950_client: fix NULL ptr reference that could occur if two clients
61 connected concurrently and if max-sockets was in effect.
65 Fix bug 3497 - Metaproxy unstable while stopping.
67 Fix bug 3495 - SEGV in SRU filter.
71 Filter multi throws diagnostic 'Present Out of Range' when
72 appropriate - rather than returning 0 records.
74 Filter virt_db: fix bad result reuse. Could happen if a result
75 was overriden and a backend did not supported named result sets.
79 Filter log: category access logs diagnostics even if searchStatus
80 or presentStatus is 'success'.
84 The SRU to Z39.50 filter does repeated Z39.50 present requests
85 to fetch all records. Needed when a Z39.50 server returns partial
86 results (due to message size limits).
90 Metaproxy now kills all child processes that are spawned by
91 modules (in case of fork, exec).
95 Debian package now installs /etc/metaproxy/metaproxy.xml which
96 includes all XML files /etc/metaproxy/filters-enabled .
97 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
101 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
102 development package to facilitate 3rd party Metaproxy modules.
104 --- 1.0.23 2010/01/04
106 Filter virt_db: Close backend filter session when Init rejected is received
107 from it (in which case it's not really closed yet). This will ensure we don't
108 run out of resources such as FDs in this case.
110 sru_z3950 filter: Accept any database (including those not listed).
112 --- 1.0.22 2009/12/03
114 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
115 later which means YAZ 3.0.47 or later.
117 --- 1.0.20 2009/11/19
119 For filter virt_db, the database is a glob pattern and the virtual
120 database sections are consulted in the order given.
122 --- 1.0.19 2009/07/08
124 For filter multi, the target (for routing) may be given as a glob-pattern.
126 More documentation for filters virt_db and multi.
128 Update schema to allow for no database in sru_z3950 filter.
130 --- 1.0.18 2009/06/30
132 Added limit filter to put sleep (penalty) for heavy use.
134 Filter frontend_net may be configured to limit the number of new connections
135 from same IP to some value (connect-max).
137 Fixed the load_balance filter.
139 --- 1.0.17 2009/06/16
141 Fix path for metaproxy executable for Debian init.d script.
143 --- 1.0.16 2009/06/10
145 SRU to Z39.50 filter honors x-username and x-password. If only
146 x-username is given that translates to open authentication (Z39.50v2). If
147 both x-username and x-password is present that translates to idPass
148 authentication (Z39.50v3).
150 New facility to change current working directory (-w).
152 Update to upstream skeleton of init.d script. Should fix bug #2619.
154 Filter session_shared now caches records (used to only cache connections
157 Filter session_shared now invalidates a Z39.50 session if a server
158 returns -1 hits. This facility was also part of yazproxy and gets around
159 a bug in Voyager-based Z39.50 servers.
161 --- 1.0.15 2008/11/18
163 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
165 --- 1.0.14 2008/06/09
167 Fixed the value of SRU record schema in searchRetrieve response. It was set
168 to a fixed value of "dc" before.
170 Serialize identical SRU requests. This is useful if HTTP client software
171 fires identical requests against metaproxy.
173 Allow Z39.50 target to be specified for SRU requests by using SRU extra
174 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
175 avoid static configuration. This facility is handled by the sru_z3950 module
176 and the z3950_client module.
178 Allow maximum number of sockets to be used for a Z39.50 client by the
179 use of SRU extra parameter x-max-sockets. This facility is handled by the
180 sru_z3950 module and the z3950_client module.
182 --- 1.0.13.1 2008/02/29
184 Simplified check for Boost libraries.
186 --- 1.0.13 2008/02/29
188 First Debian package.
190 The sru_z9350 filter now recognizes SRU parameter z-target as being
191 a ZURL of the form host/database .
193 Mergetype may be specified for filter 'multi'.
195 --- 1.0.12 2007/09/19
197 Fixed problem in Makefile WRT library specifictions. This could produce
198 linker errors (when they should not happen).
200 Fixed bug #1341: MetaProxy returning different results. Problem was that
201 fix-up of record database did not normalize the database name.
203 Documentation updates for Windows compilation.
205 --- 1.0.11 2007/06/14
207 Fixed problem with logfile being truncated.
209 --- 1.0.10 2007/05/23
211 Fixed bug #1136: Access rights not enforced.
213 Extension for log module. The log category 'access' logs more details.
214 New category 'user-access' added which is simlar to 'access' but adds
215 the Z39.50 user as for all entries in a session.
219 Added support for configurable default/force target/vhost for module Z39.50
224 Implemented filter, session_shared, which optimizes usage of Z39.50
225 sessions and result sets.
227 New filter, record_transform, which converts MARC/XML records.
229 New filter, sru_z3950, which converts SRU to Z39.50 packages.
231 New filter, load_balance, in development.
233 New filter, zeerex_xplain.
235 XML framework for config files started.
237 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
238 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
239 XML config files are checked against RNG and XML Schema's.
241 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
242 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
243 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
244 explain record to YAZ CQL-to-PQF text config file.
248 Added 'timeout' setting for filter frontend_net which specifies the number
249 of seconds a session is idle before it is closed. Default timeout is
254 Database name in records returned set for virt_db/multi filters.
256 Filter session_shared now functional.
258 Log filter can be configured to write to a given file using 'filename'
259 element. Also information category can be specified with 'category'. If
260 filename is omitted, the log filter writes to stdout. See etc/config5.xml
265 Fixed compilation on Windows.
269 Added documentation for the hidenavailable option for the multi filter.
273 Fixed bug #573: Hide errors for individual servers. If the element
274 'hideunavailable' is given in the configuration, individual servers
275 being unavailable are hidden (unless all are unavailable).
277 Fixed bug #574: Database names are recognised case-sensitively.
279 Fixed bug #567: Fix up database name in Name-Plus-Record.
281 Fixed bug #568: Update win/makefile for VS 2005.
283 Fixed bug #569: Some options throws unknown exception.
287 More information about virtual hosts. The 'etc' directory is part of the
292 Build instructions for Windows. NMake makefile part of distribution tar.
298 Filters functional: auth_simple, backend_test, frontend_net, http_file,
299 log, multi, query_rewrite, template, virt_db, z3950_client.
301 Filters in development: session_shared.
303 Pseudo-filters: template, dl
