2 zoom: relay realm to cproxy parameter file.
4 Configuration: Allow filter collection element inside route. This
5 makes it possible to include multiple filters at once.
7 zoom: nocproxy also disables urlRecipe
11 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
12 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
13 90: "Unsupported direction value".
15 zoom: honor database argument nocproxy. This disables creating a content
16 connector session (for non-CF targets, usually) and also relays nocproxy
17 as database argument to a CF target.
21 zoom: Multiple proxy hosts may be given for proxy rich database
22 parameter. List is comma separated.
24 http_file: decodes URI paths properly. Does not return 404: not found
25 if no prefix are matches. Instead packages are passed on.
29 zoom: content-{user,password,proxy} are passed on to content proxy
30 system and takes precedence over user,password,proxy .
32 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
33 with a log element including log material from children filters. At
34 this point, only the zoom filter uses this log facility. It will
35 eventually be used by other filters as well. In particular it might be
36 useful for this feature to track all filters in used during a search.
38 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
39 and queries as they are manipulated are logged.
41 zoom: extend addinfo with native diagnostics. Diagnostics as received
42 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
43 diagnostics. This indicates both a backend diagnostic and the original
46 zoom: default urlRecipe value is ${md-electronic-url}
48 zoom: target profile setting sruVersion is recognized.
52 zoom: log target profile record fetched (AKA Torus).
56 Change target profile parameter CfSubDb to CfSubDB.
60 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
61 makes sense to the zoom module itself).
65 zoom: realm may be given as part of database.
69 Fix Origin class assigment method; was removd by mistake in 1.3.12.
73 zoom: database args x-name=value are passed through to backend database.
75 SRU filter: user may specify session ID that is passed to log entries
76 that follows. It is specified by using x-session-id in the SRU arguments.
78 zoom: fix null pointer reference which would occur for bad url parameter
79 inside "torus" or if url was not given.
82 Fix bug in filter session_shared where sessions would not expire
83 properly (session ttl). This in turn could make the target close the
84 connection before expected and session_shared would return diagnostic
85 2: system temporarily available.
89 zoom: new target profile setting: sortmap_field. If sortmap_field is given
90 the field is mapped to the value for the sortmap. Values not matching
91 sortmap_field are passed verbatim.
93 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
94 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
95 depending on whether RPN or CQL is actually sent to the target.
99 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
101 zoom: For content proxy authentication is stored in param name
102 "auth", instead of "authentication".
106 zoom: relay schema in SRU mode. Previously recordSchema was not affected
111 zoom: new target profile element literalTransform that holds XSLT
112 (encoded as string) for target. Only if present and non-zero length it is
113 considered present. This takes precedence over transform.
115 Don't rely on trang anymore for Git checkout builds. Configuration in etc
116 will only be properly validated if trang is available. From now on only
117 relax NC files are bundled with the source dist.
119 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
120 component was not detected when it should be.
124 z3950_client: mark non-surrogate diagnostics from backend.
126 zoom: a proxy may be specified for HTTP fetch of target profiles.
130 Honor piggyback. Makes some SRU targets behave that insist on
131 maximumRecords > 0, but also increases performance.
135 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
136 file was not update for libdir/metaproxy4 in version 1.3.2.
140 Change location of Metaproxy modules from libdir/metaproxy to
141 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
142 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
144 New facility to dump APDUs from zoom filter. Enabled by
145 <log apdu="true"/> in the zoom filter configuation.
147 zoom filter bug fix: SRU diagnostics received from backend was
148 not properly converted to Bib-1 diagnostics.
150 Package metaproxy depends on libmetaproxy4, same version.
154 zoom: fix a bug WRT passing authentication parameters to backends.
158 Fixes for windows Makefile.
160 --- 1.2.10 2011/07/25
162 Change major version of metaproxy library from 3 to 4. This in turn
163 makes new package names for Debian and RPM.
167 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
170 zoom: configurable element sets for record transforms.
172 zoom: the target profile based transform is specified by element_transform
173 in element torus of of the ZOOM filter configuration ; default value
174 is "pz2". Target profile based retrieval is specified by element_raw
175 in configuration. It will perform same steps, but omit the XSL transform.
176 Default value is "raw".
178 zoom: element set is omitted if not set in profile. But only if pz2
179 transform is in effect. Previously the default element set was to "F".
181 zoom: For non-CF targets database arguments are parsed. User may supply
182 db,user=myuser&password=mypass for non-CF targets. These values override
183 what's given the authentication from the target profile.
185 session_shared: fix reference to freed memory. Would occur if a search
186 response had non-surrogate diagnostics.
190 Route may be given for each port in frontend_net.
194 Documentation for zoom filter. Local target profiles may be specified.
196 Fixes for zoom filter.
200 First version with zoom filter.
204 Filter z3950_client may be configured to always send a close APDU
205 to backend target when connection/session is closed. This will only
206 happen if close APDU is not already sent. Enabled by configuration
207 for z3950_client (force_close).
209 Filter virt_db and multi: relay close APDU.
211 Filter virt_db and multi: relay init size parameters
212 preferredMessageSize and maximumRecordSize.
214 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
218 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
220 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
221 as determined by configure.
223 RPM: Release includes 'indexdata' name. Use indexdata in release name so
224 this package can be distinguished from other vendors.
228 Fix filter multi: relay idAuthentication parameters.
232 Add metaproxy-config for returning compiler flags, libraries.
236 Fix --with-boost=PREFIX .
240 session_shared: fix use of maintenance thread.
242 Introduce 'start' method for filters and routers. It gets called after
243 configure and after fork, but before processing. This changes API -
244 from libmetaproxy2 to libmetaproxy3.
248 session_shared: ensure backend session is closed if init rejected
251 z3950_client: fix NULL ptr reference that could occur if two clients
252 connected concurrently and if max-sockets was in effect.
256 Fix bug 3497 - Metaproxy unstable while stopping.
258 Fix bug 3495 - SEGV in SRU filter.
262 Filter multi throws diagnostic 'Present Out of Range' when
263 appropriate - rather than returning 0 records.
265 Filter virt_db: fix bad result reuse. Could happen if a result
266 was overriden and a backend did not supported named result sets.
270 Filter log: category access logs diagnostics even if searchStatus
271 or presentStatus is 'success'.
275 The SRU to Z39.50 filter does repeated Z39.50 present requests
276 to fetch all records. Needed when a Z39.50 server returns partial
277 results (due to message size limits).
281 Metaproxy now kills all child processes that are spawned by
282 modules (in case of fork, exec).
286 Debian package now installs /etc/metaproxy/metaproxy.xml which
287 includes all XML files /etc/metaproxy/filters-enabled .
288 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
292 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
293 development package to facilitate 3rd party Metaproxy modules.
295 --- 1.0.23 2010/01/04
297 Filter virt_db: Close backend filter session when Init rejected is received
298 from it (in which case it's not really closed yet). This will ensure we don't
299 run out of resources such as FDs in this case.
301 sru_z3950 filter: Accept any database (including those not listed).
303 --- 1.0.22 2009/12/03
305 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
306 later which means YAZ 3.0.47 or later.
308 --- 1.0.20 2009/11/19
310 For filter virt_db, the database is a glob pattern and the virtual
311 database sections are consulted in the order given.
313 --- 1.0.19 2009/07/08
315 For filter multi, the target (for routing) may be given as a glob-pattern.
317 More documentation for filters virt_db and multi.
319 Update schema to allow for no database in sru_z3950 filter.
321 --- 1.0.18 2009/06/30
323 Added limit filter to put sleep (penalty) for heavy use.
325 Filter frontend_net may be configured to limit the number of new connections
326 from same IP to some value (connect-max).
328 Fixed the load_balance filter.
330 --- 1.0.17 2009/06/16
332 Fix path for metaproxy executable for Debian init.d script.
334 --- 1.0.16 2009/06/10
336 SRU to Z39.50 filter honors x-username and x-password. If only
337 x-username is given that translates to open authentication (Z39.50v2). If
338 both x-username and x-password is present that translates to idPass
339 authentication (Z39.50v3).
341 New facility to change current working directory (-w).
343 Update to upstream skeleton of init.d script. Should fix bug #2619.
345 Filter session_shared now caches records (used to only cache connections
348 Filter session_shared now invalidates a Z39.50 session if a server
349 returns -1 hits. This facility was also part of yazproxy and gets around
350 a bug in Voyager-based Z39.50 servers.
352 --- 1.0.15 2008/11/18
354 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
356 --- 1.0.14 2008/06/09
358 Fixed the value of SRU record schema in searchRetrieve response. It was set
359 to a fixed value of "dc" before.
361 Serialize identical SRU requests. This is useful if HTTP client software
362 fires identical requests against metaproxy.
364 Allow Z39.50 target to be specified for SRU requests by using SRU extra
365 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
366 avoid static configuration. This facility is handled by the sru_z3950 module
367 and the z3950_client module.
369 Allow maximum number of sockets to be used for a Z39.50 client by the
370 use of SRU extra parameter x-max-sockets. This facility is handled by the
371 sru_z3950 module and the z3950_client module.
373 --- 1.0.13.1 2008/02/29
375 Simplified check for Boost libraries.
377 --- 1.0.13 2008/02/29
379 First Debian package.
381 The sru_z9350 filter now recognizes SRU parameter z-target as being
382 a ZURL of the form host/database .
384 Mergetype may be specified for filter 'multi'.
386 --- 1.0.12 2007/09/19
388 Fixed problem in Makefile WRT library specifictions. This could produce
389 linker errors (when they should not happen).
391 Fixed bug #1341: MetaProxy returning different results. Problem was that
392 fix-up of record database did not normalize the database name.
394 Documentation updates for Windows compilation.
396 --- 1.0.11 2007/06/14
398 Fixed problem with logfile being truncated.
400 --- 1.0.10 2007/05/23
402 Fixed bug #1136: Access rights not enforced.
404 Extension for log module. The log category 'access' logs more details.
405 New category 'user-access' added which is simlar to 'access' but adds
406 the Z39.50 user as for all entries in a session.
410 Added support for configurable default/force target/vhost for module Z39.50
415 Implemented filter, session_shared, which optimizes usage of Z39.50
416 sessions and result sets.
418 New filter, record_transform, which converts MARC/XML records.
420 New filter, sru_z3950, which converts SRU to Z39.50 packages.
422 New filter, load_balance, in development.
424 New filter, zeerex_xplain.
426 XML framework for config files started.
428 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
429 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
430 XML config files are checked against RNG and XML Schema's.
432 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
433 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
434 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
435 explain record to YAZ CQL-to-PQF text config file.
439 Added 'timeout' setting for filter frontend_net which specifies the number
440 of seconds a session is idle before it is closed. Default timeout is
445 Database name in records returned set for virt_db/multi filters.
447 Filter session_shared now functional.
449 Log filter can be configured to write to a given file using 'filename'
450 element. Also information category can be specified with 'category'. If
451 filename is omitted, the log filter writes to stdout. See etc/config5.xml
456 Fixed compilation on Windows.
460 Added documentation for the hidenavailable option for the multi filter.
464 Fixed bug #573: Hide errors for individual servers. If the element
465 'hideunavailable' is given in the configuration, individual servers
466 being unavailable are hidden (unless all are unavailable).
468 Fixed bug #574: Database names are recognised case-sensitively.
470 Fixed bug #567: Fix up database name in Name-Plus-Record.
472 Fixed bug #568: Update win/makefile for VS 2005.
474 Fixed bug #569: Some options throws unknown exception.
478 More information about virtual hosts. The 'etc' directory is part of the
483 Build instructions for Windows. NMake makefile part of distribution tar.
489 Filters functional: auth_simple, backend_test, frontend_net, http_file,
490 log, multi, query_rewrite, template, virt_db, z3950_client.
492 Filters in development: session_shared.
494 Pseudo-filters: template, dl
