3 Change major version of metaproxy library from 3 to 4. This in turn
4 makes new package names for Debian and RPM.
8 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
11 zoom: configurable element sets for record transforms.
13 zoom: the target profile based transform is specified by element_transform
14 in element torus of of the ZOOM filter configuration ; default value
15 is "pz2". Target profile based retrieval is specified by element_raw
16 in configuration. It will perform same steps, but omit the XSL transform.
17 Default value is "raw".
19 zoom: element set is omitted if not set in profile. But only if pz2
20 transform is in effect. Previously the default element set was to "F".
22 zoom: For non-CF targets database arguments are parsed. User may supply
23 db,user=myuser&password=mypass for non-CF targets. These values override
24 what's given the authentication from the target profile.
26 session_shared: fix reference to freed memory. Would occur if a search
27 response had non-surrogate diagnostics.
31 Route may be given for each port in frontend_net.
35 Documentation for zoom filter. Local target profiles may be specified.
37 Fixes for zoom filter.
41 First version with zoom filter.
45 Filter z3950_client may be configured to always send a close APDU
46 to backend target when connection/session is closed. This will only
47 happen if close APDU is not already sent. Enabled by configuration
48 for z3950_client (force_close).
50 Filter virt_db and multi: relay close APDU.
52 Filter virt_db and multi: relay init size parameters
53 preferredMessageSize and maximumRecordSize.
55 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
59 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
61 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
62 as determined by configure.
64 RPM: Release includes 'indexdata' name. Use indexdata in release name so
65 this package can be distinguished from other vendors.
69 Fix filter multi: relay idAuthentication parameters.
73 Add metaproxy-config for returning compiler flags, libraries.
77 Fix --with-boost=PREFIX .
81 session_shared: fix use of maintenance thread.
83 Introduce 'start' method for filters and routers. It gets called after
84 configure and after fork, but before processing. This changes API -
85 from libmetaproxy2 to libmetaproxy3.
89 session_shared: ensure backend session is closed if init rejected
92 z3950_client: fix NULL ptr reference that could occur if two clients
93 connected concurrently and if max-sockets was in effect.
97 Fix bug 3497 - Metaproxy unstable while stopping.
99 Fix bug 3495 - SEGV in SRU filter.
103 Filter multi throws diagnostic 'Present Out of Range' when
104 appropriate - rather than returning 0 records.
106 Filter virt_db: fix bad result reuse. Could happen if a result
107 was overriden and a backend did not supported named result sets.
111 Filter log: category access logs diagnostics even if searchStatus
112 or presentStatus is 'success'.
116 The SRU to Z39.50 filter does repeated Z39.50 present requests
117 to fetch all records. Needed when a Z39.50 server returns partial
118 results (due to message size limits).
122 Metaproxy now kills all child processes that are spawned by
123 modules (in case of fork, exec).
127 Debian package now installs /etc/metaproxy/metaproxy.xml which
128 includes all XML files /etc/metaproxy/filters-enabled .
129 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
133 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
134 development package to facilitate 3rd party Metaproxy modules.
136 --- 1.0.23 2010/01/04
138 Filter virt_db: Close backend filter session when Init rejected is received
139 from it (in which case it's not really closed yet). This will ensure we don't
140 run out of resources such as FDs in this case.
142 sru_z3950 filter: Accept any database (including those not listed).
144 --- 1.0.22 2009/12/03
146 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
147 later which means YAZ 3.0.47 or later.
149 --- 1.0.20 2009/11/19
151 For filter virt_db, the database is a glob pattern and the virtual
152 database sections are consulted in the order given.
154 --- 1.0.19 2009/07/08
156 For filter multi, the target (for routing) may be given as a glob-pattern.
158 More documentation for filters virt_db and multi.
160 Update schema to allow for no database in sru_z3950 filter.
162 --- 1.0.18 2009/06/30
164 Added limit filter to put sleep (penalty) for heavy use.
166 Filter frontend_net may be configured to limit the number of new connections
167 from same IP to some value (connect-max).
169 Fixed the load_balance filter.
171 --- 1.0.17 2009/06/16
173 Fix path for metaproxy executable for Debian init.d script.
175 --- 1.0.16 2009/06/10
177 SRU to Z39.50 filter honors x-username and x-password. If only
178 x-username is given that translates to open authentication (Z39.50v2). If
179 both x-username and x-password is present that translates to idPass
180 authentication (Z39.50v3).
182 New facility to change current working directory (-w).
184 Update to upstream skeleton of init.d script. Should fix bug #2619.
186 Filter session_shared now caches records (used to only cache connections
189 Filter session_shared now invalidates a Z39.50 session if a server
190 returns -1 hits. This facility was also part of yazproxy and gets around
191 a bug in Voyager-based Z39.50 servers.
193 --- 1.0.15 2008/11/18
195 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
197 --- 1.0.14 2008/06/09
199 Fixed the value of SRU record schema in searchRetrieve response. It was set
200 to a fixed value of "dc" before.
202 Serialize identical SRU requests. This is useful if HTTP client software
203 fires identical requests against metaproxy.
205 Allow Z39.50 target to be specified for SRU requests by using SRU extra
206 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
207 avoid static configuration. This facility is handled by the sru_z3950 module
208 and the z3950_client module.
210 Allow maximum number of sockets to be used for a Z39.50 client by the
211 use of SRU extra parameter x-max-sockets. This facility is handled by the
212 sru_z3950 module and the z3950_client module.
214 --- 1.0.13.1 2008/02/29
216 Simplified check for Boost libraries.
218 --- 1.0.13 2008/02/29
220 First Debian package.
222 The sru_z9350 filter now recognizes SRU parameter z-target as being
223 a ZURL of the form host/database .
225 Mergetype may be specified for filter 'multi'.
227 --- 1.0.12 2007/09/19
229 Fixed problem in Makefile WRT library specifictions. This could produce
230 linker errors (when they should not happen).
232 Fixed bug #1341: MetaProxy returning different results. Problem was that
233 fix-up of record database did not normalize the database name.
235 Documentation updates for Windows compilation.
237 --- 1.0.11 2007/06/14
239 Fixed problem with logfile being truncated.
241 --- 1.0.10 2007/05/23
243 Fixed bug #1136: Access rights not enforced.
245 Extension for log module. The log category 'access' logs more details.
246 New category 'user-access' added which is simlar to 'access' but adds
247 the Z39.50 user as for all entries in a session.
251 Added support for configurable default/force target/vhost for module Z39.50
256 Implemented filter, session_shared, which optimizes usage of Z39.50
257 sessions and result sets.
259 New filter, record_transform, which converts MARC/XML records.
261 New filter, sru_z3950, which converts SRU to Z39.50 packages.
263 New filter, load_balance, in development.
265 New filter, zeerex_xplain.
267 XML framework for config files started.
269 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
270 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
271 XML config files are checked against RNG and XML Schema's.
273 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
274 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
275 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
276 explain record to YAZ CQL-to-PQF text config file.
280 Added 'timeout' setting for filter frontend_net which specifies the number
281 of seconds a session is idle before it is closed. Default timeout is
286 Database name in records returned set for virt_db/multi filters.
288 Filter session_shared now functional.
290 Log filter can be configured to write to a given file using 'filename'
291 element. Also information category can be specified with 'category'. If
292 filename is omitted, the log filter writes to stdout. See etc/config5.xml
297 Fixed compilation on Windows.
301 Added documentation for the hidenavailable option for the multi filter.
305 Fixed bug #573: Hide errors for individual servers. If the element
306 'hideunavailable' is given in the configuration, individual servers
307 being unavailable are hidden (unless all are unavailable).
309 Fixed bug #574: Database names are recognised case-sensitively.
311 Fixed bug #567: Fix up database name in Name-Plus-Record.
313 Fixed bug #568: Update win/makefile for VS 2005.
315 Fixed bug #569: Some options throws unknown exception.
319 More information about virtual hosts. The 'etc' directory is part of the
324 Build instructions for Windows. NMake makefile part of distribution tar.
330 Filters functional: auth_simple, backend_test, frontend_net, http_file,
331 log, multi, query_rewrite, template, virt_db, z3950_client.
333 Filters in development: session_shared.
335 Pseudo-filters: template, dl
