3 zoom: fix a bug WRT passing authentication parameters to backends.
7 Fixes for windows Makefile.
11 Change major version of metaproxy library from 3 to 4. This in turn
12 makes new package names for Debian and RPM.
16 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
19 zoom: configurable element sets for record transforms.
21 zoom: the target profile based transform is specified by element_transform
22 in element torus of of the ZOOM filter configuration ; default value
23 is "pz2". Target profile based retrieval is specified by element_raw
24 in configuration. It will perform same steps, but omit the XSL transform.
25 Default value is "raw".
27 zoom: element set is omitted if not set in profile. But only if pz2
28 transform is in effect. Previously the default element set was to "F".
30 zoom: For non-CF targets database arguments are parsed. User may supply
31 db,user=myuser&password=mypass for non-CF targets. These values override
32 what's given the authentication from the target profile.
34 session_shared: fix reference to freed memory. Would occur if a search
35 response had non-surrogate diagnostics.
39 Route may be given for each port in frontend_net.
43 Documentation for zoom filter. Local target profiles may be specified.
45 Fixes for zoom filter.
49 First version with zoom filter.
53 Filter z3950_client may be configured to always send a close APDU
54 to backend target when connection/session is closed. This will only
55 happen if close APDU is not already sent. Enabled by configuration
56 for z3950_client (force_close).
58 Filter virt_db and multi: relay close APDU.
60 Filter virt_db and multi: relay init size parameters
61 preferredMessageSize and maximumRecordSize.
63 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
67 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
69 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
70 as determined by configure.
72 RPM: Release includes 'indexdata' name. Use indexdata in release name so
73 this package can be distinguished from other vendors.
77 Fix filter multi: relay idAuthentication parameters.
81 Add metaproxy-config for returning compiler flags, libraries.
85 Fix --with-boost=PREFIX .
89 session_shared: fix use of maintenance thread.
91 Introduce 'start' method for filters and routers. It gets called after
92 configure and after fork, but before processing. This changes API -
93 from libmetaproxy2 to libmetaproxy3.
97 session_shared: ensure backend session is closed if init rejected
100 z3950_client: fix NULL ptr reference that could occur if two clients
101 connected concurrently and if max-sockets was in effect.
105 Fix bug 3497 - Metaproxy unstable while stopping.
107 Fix bug 3495 - SEGV in SRU filter.
111 Filter multi throws diagnostic 'Present Out of Range' when
112 appropriate - rather than returning 0 records.
114 Filter virt_db: fix bad result reuse. Could happen if a result
115 was overriden and a backend did not supported named result sets.
119 Filter log: category access logs diagnostics even if searchStatus
120 or presentStatus is 'success'.
124 The SRU to Z39.50 filter does repeated Z39.50 present requests
125 to fetch all records. Needed when a Z39.50 server returns partial
126 results (due to message size limits).
130 Metaproxy now kills all child processes that are spawned by
131 modules (in case of fork, exec).
135 Debian package now installs /etc/metaproxy/metaproxy.xml which
136 includes all XML files /etc/metaproxy/filters-enabled .
137 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
141 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
142 development package to facilitate 3rd party Metaproxy modules.
144 --- 1.0.23 2010/01/04
146 Filter virt_db: Close backend filter session when Init rejected is received
147 from it (in which case it's not really closed yet). This will ensure we don't
148 run out of resources such as FDs in this case.
150 sru_z3950 filter: Accept any database (including those not listed).
152 --- 1.0.22 2009/12/03
154 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
155 later which means YAZ 3.0.47 or later.
157 --- 1.0.20 2009/11/19
159 For filter virt_db, the database is a glob pattern and the virtual
160 database sections are consulted in the order given.
162 --- 1.0.19 2009/07/08
164 For filter multi, the target (for routing) may be given as a glob-pattern.
166 More documentation for filters virt_db and multi.
168 Update schema to allow for no database in sru_z3950 filter.
170 --- 1.0.18 2009/06/30
172 Added limit filter to put sleep (penalty) for heavy use.
174 Filter frontend_net may be configured to limit the number of new connections
175 from same IP to some value (connect-max).
177 Fixed the load_balance filter.
179 --- 1.0.17 2009/06/16
181 Fix path for metaproxy executable for Debian init.d script.
183 --- 1.0.16 2009/06/10
185 SRU to Z39.50 filter honors x-username and x-password. If only
186 x-username is given that translates to open authentication (Z39.50v2). If
187 both x-username and x-password is present that translates to idPass
188 authentication (Z39.50v3).
190 New facility to change current working directory (-w).
192 Update to upstream skeleton of init.d script. Should fix bug #2619.
194 Filter session_shared now caches records (used to only cache connections
197 Filter session_shared now invalidates a Z39.50 session if a server
198 returns -1 hits. This facility was also part of yazproxy and gets around
199 a bug in Voyager-based Z39.50 servers.
201 --- 1.0.15 2008/11/18
203 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
205 --- 1.0.14 2008/06/09
207 Fixed the value of SRU record schema in searchRetrieve response. It was set
208 to a fixed value of "dc" before.
210 Serialize identical SRU requests. This is useful if HTTP client software
211 fires identical requests against metaproxy.
213 Allow Z39.50 target to be specified for SRU requests by using SRU extra
214 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
215 avoid static configuration. This facility is handled by the sru_z3950 module
216 and the z3950_client module.
218 Allow maximum number of sockets to be used for a Z39.50 client by the
219 use of SRU extra parameter x-max-sockets. This facility is handled by the
220 sru_z3950 module and the z3950_client module.
222 --- 1.0.13.1 2008/02/29
224 Simplified check for Boost libraries.
226 --- 1.0.13 2008/02/29
228 First Debian package.
230 The sru_z9350 filter now recognizes SRU parameter z-target as being
231 a ZURL of the form host/database .
233 Mergetype may be specified for filter 'multi'.
235 --- 1.0.12 2007/09/19
237 Fixed problem in Makefile WRT library specifictions. This could produce
238 linker errors (when they should not happen).
240 Fixed bug #1341: MetaProxy returning different results. Problem was that
241 fix-up of record database did not normalize the database name.
243 Documentation updates for Windows compilation.
245 --- 1.0.11 2007/06/14
247 Fixed problem with logfile being truncated.
249 --- 1.0.10 2007/05/23
251 Fixed bug #1136: Access rights not enforced.
253 Extension for log module. The log category 'access' logs more details.
254 New category 'user-access' added which is simlar to 'access' but adds
255 the Z39.50 user as for all entries in a session.
259 Added support for configurable default/force target/vhost for module Z39.50
264 Implemented filter, session_shared, which optimizes usage of Z39.50
265 sessions and result sets.
267 New filter, record_transform, which converts MARC/XML records.
269 New filter, sru_z3950, which converts SRU to Z39.50 packages.
271 New filter, load_balance, in development.
273 New filter, zeerex_xplain.
275 XML framework for config files started.
277 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
278 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
279 XML config files are checked against RNG and XML Schema's.
281 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
282 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
283 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
284 explain record to YAZ CQL-to-PQF text config file.
288 Added 'timeout' setting for filter frontend_net which specifies the number
289 of seconds a session is idle before it is closed. Default timeout is
294 Database name in records returned set for virt_db/multi filters.
296 Filter session_shared now functional.
298 Log filter can be configured to write to a given file using 'filename'
299 element. Also information category can be specified with 'category'. If
300 filename is omitted, the log filter writes to stdout. See etc/config5.xml
305 Fixed compilation on Windows.
309 Added documentation for the hidenavailable option for the multi filter.
313 Fixed bug #573: Hide errors for individual servers. If the element
314 'hideunavailable' is given in the configuration, individual servers
315 being unavailable are hidden (unless all are unavailable).
317 Fixed bug #574: Database names are recognised case-sensitively.
319 Fixed bug #567: Fix up database name in Name-Plus-Record.
321 Fixed bug #568: Update win/makefile for VS 2005.
323 Fixed bug #569: Some options throws unknown exception.
327 More information about virtual hosts. The 'etc' directory is part of the
332 Build instructions for Windows. NMake makefile part of distribution tar.
338 Filters functional: auth_simple, backend_test, frontend_net, http_file,
339 log, multi, query_rewrite, template, virt_db, z3950_client.
341 Filters in development: session_shared.
343 Pseudo-filters: template, dl
