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