3 Fix --with-boost=PREFIX .
7 session_shared: fix use of maintenance thread.
9 Introduce 'start' method for filters and routers. It gets called after
10 configure and after fork, but before processing. This changes API -
11 from libmetaproxy2 to libmetaproxy3.
15 session_shared: ensure backend session is closed if init rejected
18 z3950_client: fix NULL ptr reference that could occur if two clients
19 connected concurrently and if max-sockets was in effect.
23 Fix bug 3497 - Metaproxy unstable while stopping.
25 Fix bug 3495 - SEGV in SRU filter.
29 Filter multi throws diagnostic 'Present Out of Range' when
30 appropriate - rather than returning 0 records.
32 Filter virt_db: fix bad result reuse. Could happen if a result
33 was overriden and a backend did not supported named result sets.
37 Filter log: category access logs diagnostics even if searchStatus
38 or presentStatus is 'success'.
42 The SRU to Z39.50 filter does repeated Z39.50 present requests
43 to fetch all records. Needed when a Z39.50 server returns partial
44 results (due to message size limits).
48 Metaproxy now kills all child processes that are spawned by
49 modules (in case of fork, exec).
53 Debian package now installs /etc/metaproxy/metaproxy.xml which
54 includes all XML files /etc/metaproxy/filters-enabled .
55 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
59 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
60 development package to facilitate 3rd party Metaproxy modules.
64 Filter virt_db: Close backend filter session when Init rejected is received
65 from it (in which case it's not really closed yet). This will ensure we don't
66 run out of resources such as FDs in this case.
68 sru_z3950 filter: Accept any database (including those not listed).
72 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
73 later which means YAZ 3.0.47 or later.
77 For filter virt_db, the database is a glob pattern and the virtual
78 database sections are consulted in the order given.
82 For filter multi, the target (for routing) may be given as a glob-pattern.
84 More documentation for filters virt_db and multi.
86 Update schema to allow for no database in sru_z3950 filter.
90 Added limit filter to put sleep (penalty) for heavy use.
92 Filter frontend_net may be configured to limit the number of new connections
93 from same IP to some value (connect-max).
95 Fixed the load_balance filter.
99 Fix path for metaproxy executable for Debian init.d script.
101 --- 1.0.16 2009/06/10
103 SRU to Z39.50 filter honors x-username and x-password. If only
104 x-username is given that translates to open authentication (Z39.50v2). If
105 both x-username and x-password is present that translates to idPass
106 authentication (Z39.50v3).
108 New facility to change current working directory (-w).
110 Update to upstream skeleton of init.d script. Should fix bug #2619.
112 Filter session_shared now caches records (used to only cache connections
115 Filter session_shared now invalidates a Z39.50 session if a server
116 returns -1 hits. This facility was also part of yazproxy and gets around
117 a bug in Voyager-based Z39.50 servers.
119 --- 1.0.15 2008/11/18
121 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
123 --- 1.0.14 2008/06/09
125 Fixed the value of SRU record schema in searchRetrieve response. It was set
126 to a fixed value of "dc" before.
128 Serialize identical SRU requests. This is useful if HTTP client software
129 fires identical requests against metaproxy.
131 Allow Z39.50 target to be specified for SRU requests by using SRU extra
132 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
133 avoid static configuration. This facility is handled by the sru_z3950 module
134 and the z3950_client module.
136 Allow maximum number of sockets to be used for a Z39.50 client by the
137 use of SRU extra parameter x-max-sockets. This facility is handled by the
138 sru_z3950 module and the z3950_client module.
140 --- 1.0.13.1 2008/02/29
142 Simplified check for Boost libraries.
144 --- 1.0.13 2008/02/29
146 First Debian package.
148 The sru_z9350 filter now recognizes SRU parameter z-target as being
149 a ZURL of the form host/database .
151 Mergetype may be specified for filter 'multi'.
153 --- 1.0.12 2007/09/19
155 Fixed problem in Makefile WRT library specifictions. This could produce
156 linker errors (when they should not happen).
158 Fixed bug #1341: MetaProxy returning different results. Problem was that
159 fix-up of record database did not normalize the database name.
161 Documentation updates for Windows compilation.
163 --- 1.0.11 2007/06/14
165 Fixed problem with logfile being truncated.
167 --- 1.0.10 2007/05/23
169 Fixed bug #1136: Access rights not enforced.
171 Extension for log module. The log category 'access' logs more details.
172 New category 'user-access' added which is simlar to 'access' but adds
173 the Z39.50 user as for all entries in a session.
177 Added support for configurable default/force target/vhost for module Z39.50
182 Implemented filter, session_shared, which optimizes usage of Z39.50
183 sessions and result sets.
185 New filter, record_transform, which converts MARC/XML records.
187 New filter, sru_z3950, which converts SRU to Z39.50 packages.
189 New filter, load_balance, in development.
191 New filter, zeerex_xplain.
193 XML framework for config files started.
195 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
196 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
197 XML config files are checked against RNG and XML Schema's.
199 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
200 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
201 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
202 explain record to YAZ CQL-to-PQF text config file.
206 Added 'timeout' setting for filter frontend_net which specifies the number
207 of seconds a session is idle before it is closed. Default timeout is
212 Database name in records returned set for virt_db/multi filters.
214 Filter session_shared now functional.
216 Log filter can be configured to write to a given file using 'filename'
217 element. Also information category can be specified with 'category'. If
218 filename is omitted, the log filter writes to stdout. See etc/config5.xml
223 Fixed compilation on Windows.
227 Added documentation for the hidenavailable option for the multi filter.
231 Fixed bug #573: Hide errors for individual servers. If the element
232 'hideunavailable' is given in the configuration, individual servers
233 being unavailable are hidden (unless all are unavailable).
235 Fixed bug #574: Database names are recognised case-sensitively.
237 Fixed bug #567: Fix up database name in Name-Plus-Record.
239 Fixed bug #568: Update win/makefile for VS 2005.
241 Fixed bug #569: Some options throws unknown exception.
245 More information about virtual hosts. The 'etc' directory is part of the
250 Build instructions for Windows. NMake makefile part of distribution tar.
256 Filters functional: auth_simple, backend_test, frontend_net, http_file,
257 log, multi, query_rewrite, template, virt_db, z3950_client.
259 Filters in development: session_shared.
261 Pseudo-filters: template, dl
