3 Fix filter multi: relay idAuthentication parameters.
7 Add metaproxy-config for returning compiler flags, libraries.
11 Fix --with-boost=PREFIX .
15 session_shared: fix use of maintenance thread.
17 Introduce 'start' method for filters and routers. It gets called after
18 configure and after fork, but before processing. This changes API -
19 from libmetaproxy2 to libmetaproxy3.
23 session_shared: ensure backend session is closed if init rejected
26 z3950_client: fix NULL ptr reference that could occur if two clients
27 connected concurrently and if max-sockets was in effect.
31 Fix bug 3497 - Metaproxy unstable while stopping.
33 Fix bug 3495 - SEGV in SRU filter.
37 Filter multi throws diagnostic 'Present Out of Range' when
38 appropriate - rather than returning 0 records.
40 Filter virt_db: fix bad result reuse. Could happen if a result
41 was overriden and a backend did not supported named result sets.
45 Filter log: category access logs diagnostics even if searchStatus
46 or presentStatus is 'success'.
50 The SRU to Z39.50 filter does repeated Z39.50 present requests
51 to fetch all records. Needed when a Z39.50 server returns partial
52 results (due to message size limits).
56 Metaproxy now kills all child processes that are spawned by
57 modules (in case of fork, exec).
61 Debian package now installs /etc/metaproxy/metaproxy.xml which
62 includes all XML files /etc/metaproxy/filters-enabled .
63 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
67 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
68 development package to facilitate 3rd party Metaproxy modules.
72 Filter virt_db: Close backend filter session when Init rejected is received
73 from it (in which case it's not really closed yet). This will ensure we don't
74 run out of resources such as FDs in this case.
76 sru_z3950 filter: Accept any database (including those not listed).
80 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
81 later which means YAZ 3.0.47 or later.
85 For filter virt_db, the database is a glob pattern and the virtual
86 database sections are consulted in the order given.
90 For filter multi, the target (for routing) may be given as a glob-pattern.
92 More documentation for filters virt_db and multi.
94 Update schema to allow for no database in sru_z3950 filter.
98 Added limit filter to put sleep (penalty) for heavy use.
100 Filter frontend_net may be configured to limit the number of new connections
101 from same IP to some value (connect-max).
103 Fixed the load_balance filter.
105 --- 1.0.17 2009/06/16
107 Fix path for metaproxy executable for Debian init.d script.
109 --- 1.0.16 2009/06/10
111 SRU to Z39.50 filter honors x-username and x-password. If only
112 x-username is given that translates to open authentication (Z39.50v2). If
113 both x-username and x-password is present that translates to idPass
114 authentication (Z39.50v3).
116 New facility to change current working directory (-w).
118 Update to upstream skeleton of init.d script. Should fix bug #2619.
120 Filter session_shared now caches records (used to only cache connections
123 Filter session_shared now invalidates a Z39.50 session if a server
124 returns -1 hits. This facility was also part of yazproxy and gets around
125 a bug in Voyager-based Z39.50 servers.
127 --- 1.0.15 2008/11/18
129 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
131 --- 1.0.14 2008/06/09
133 Fixed the value of SRU record schema in searchRetrieve response. It was set
134 to a fixed value of "dc" before.
136 Serialize identical SRU requests. This is useful if HTTP client software
137 fires identical requests against metaproxy.
139 Allow Z39.50 target to be specified for SRU requests by using SRU extra
140 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
141 avoid static configuration. This facility is handled by the sru_z3950 module
142 and the z3950_client module.
144 Allow maximum number of sockets to be used for a Z39.50 client by the
145 use of SRU extra parameter x-max-sockets. This facility is handled by the
146 sru_z3950 module and the z3950_client module.
148 --- 1.0.13.1 2008/02/29
150 Simplified check for Boost libraries.
152 --- 1.0.13 2008/02/29
154 First Debian package.
156 The sru_z9350 filter now recognizes SRU parameter z-target as being
157 a ZURL of the form host/database .
159 Mergetype may be specified for filter 'multi'.
161 --- 1.0.12 2007/09/19
163 Fixed problem in Makefile WRT library specifictions. This could produce
164 linker errors (when they should not happen).
166 Fixed bug #1341: MetaProxy returning different results. Problem was that
167 fix-up of record database did not normalize the database name.
169 Documentation updates for Windows compilation.
171 --- 1.0.11 2007/06/14
173 Fixed problem with logfile being truncated.
175 --- 1.0.10 2007/05/23
177 Fixed bug #1136: Access rights not enforced.
179 Extension for log module. The log category 'access' logs more details.
180 New category 'user-access' added which is simlar to 'access' but adds
181 the Z39.50 user as for all entries in a session.
185 Added support for configurable default/force target/vhost for module Z39.50
190 Implemented filter, session_shared, which optimizes usage of Z39.50
191 sessions and result sets.
193 New filter, record_transform, which converts MARC/XML records.
195 New filter, sru_z3950, which converts SRU to Z39.50 packages.
197 New filter, load_balance, in development.
199 New filter, zeerex_xplain.
201 XML framework for config files started.
203 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
204 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
205 XML config files are checked against RNG and XML Schema's.
207 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
208 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
209 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
210 explain record to YAZ CQL-to-PQF text config file.
214 Added 'timeout' setting for filter frontend_net which specifies the number
215 of seconds a session is idle before it is closed. Default timeout is
220 Database name in records returned set for virt_db/multi filters.
222 Filter session_shared now functional.
224 Log filter can be configured to write to a given file using 'filename'
225 element. Also information category can be specified with 'category'. If
226 filename is omitted, the log filter writes to stdout. See etc/config5.xml
231 Fixed compilation on Windows.
235 Added documentation for the hidenavailable option for the multi filter.
239 Fixed bug #573: Hide errors for individual servers. If the element
240 'hideunavailable' is given in the configuration, individual servers
241 being unavailable are hidden (unless all are unavailable).
243 Fixed bug #574: Database names are recognised case-sensitively.
245 Fixed bug #567: Fix up database name in Name-Plus-Record.
247 Fixed bug #568: Update win/makefile for VS 2005.
249 Fixed bug #569: Some options throws unknown exception.
253 More information about virtual hosts. The 'etc' directory is part of the
258 Build instructions for Windows. NMake makefile part of distribution tar.
264 Filters functional: auth_simple, backend_test, frontend_net, http_file,
265 log, multi, query_rewrite, template, virt_db, z3950_client.
267 Filters in development: session_shared.
269 Pseudo-filters: template, dl
