3 zoom: Add nocproxy=1 for contentConnector sessions MP-501
5 Doc: mention proper versions; fix link to Boost win binaries.
7 Windows: update for Boost 1.55
9 Windows: avoid warning when using boost::split. Done by defining
10 _SCL_SECURE_NO_WARNINGS for Visual Studio.
12 Fix LSB conformance for /etc/init.d/metaproxy MP-500
13 Debian: add support for /etc/init.d/metaproxy status
15 sort: Add const to Record less than operator in order to compile on
20 session_shared: fix element-set handling in record caching. MP-499
22 document http_rewrite. MP-468
24 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
25 respects the header (which will normally come from the cproxy filter)
29 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
30 RPM was unsable in version 1.4.0.
32 Remove log message about "backend classes". Appeared in version 1.4.0.
36 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
37 with older version from source, but packages now use YAZ 5 that supports
40 sru_z3950: Fix SEGV for decoding invalid SRU requests
41 Incorrect reference to union (was explain response rather than
44 session_shared: match additionalSearchInfo (includes facets). In
45 layman's terms means that means that facets are properly handled
46 by this filter. Eg a change in requested facets will issue new
47 search and facets from exisiting result set are cached.
51 http_rewrite: better handling of <script> content in HTML parser. MP-486
53 http_rewrite: fix threading issue with regex. MP-482
55 bounce: don't use strdup for fixed length content. Error occurred in echo
58 session_shared: expire backend class when no instances left. This
59 means memory clean up, but not really a leak fix.
61 virt_db: fix leak for naked ptr.
63 cql_rpn: use config relative path for cql2rpn file. MP-481
65 Updates for upcoming YAZ 5.
69 New configuration directories ports.d/routes.d for metaproxy
70 configuration. This allows 3rd party packages to install config
71 for ports and new routes. MP-477
75 Fix metaproxy-config --libs to return non-mt over mt libs.
76 The -mt versions do not exist as shared objects and cause
77 linker errors for applications linking with Metaproxy.
78 Problem present in versions 1.3.56 - 1.3.59. MP-475
80 HTML: clean up char checks. Add ptr to HTML parse spec
82 HTML parser stops eating tag when <-char is met MP-473
84 rewrite: do not even compare content types, if we don't have any
85 the regex_match caused a segfault if we had no content-type in the
88 rewrite: within header=... matches only the header value
89 Used to match the whole header line, but we need to use
90 ^$ anchoring for host-relative regexps, and they need to
91 anchor at the ends of the value. MP-470.
93 rewrite: Ruleset functional MP-469
97 session_shared: negotiate init sz parameters.
98 By default, session_shared will honor the paramters given by client.
99 An alternative, but not implemented, algorithm would be to only
100 re-use sessions with same sz parameters. This however, could reduce
101 re-use of sessions a lot. Hence this, simple algorithm instead. The
102 negotiation to a maximum sz values can be enabled by using
103 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
104 in configuration. This will make session_shared send those values
105 to backends and use returned init values in negotaition to
106 client before session_shared.
108 session_shared: resolve result-set references.
109 The reference is substitued with the query for old set if database
110 match and query type is Type-1. If not the reference will issue a
113 sort filter: relays RecordComposition including elementSet in use for
116 http_client: better diagnostics
118 http_client: disables HTTP redirect handling by default.
119 It can be configured with max-redirects in configuration.
121 --- 1.3.58 2013/06/12
123 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
125 --- 1.3.57 2013/06/12
127 Make RouterChain and RouterXML part of public API (libmetaproxy).
129 http_client: honor X-Metaproxy-Proxy as an alternative to
130 the "proxy" configuration. Allows proxy to be set per HTTP request.
132 sru_z3950: For SRU requests recognize x-client prefixes as a way
133 to ingest "database parameters".. The suffix of x-client- serves
134 as database argument name. Multiple may be given. For example:
135 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
136 is turned into Z39.50 database
139 --- 1.3.56 2013/05/27
141 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
143 New filter sd_remove, which replaces surrogate diagnostics with
144 SUTRS records. This filter tries to deal with clients that breaks
145 when receiving surrogate diagnostics.
147 new filter http_client. Same role as z3950_client, but just for
148 HTTP. Allows Metaproxy to operate as a HTTP proxy.
150 New filter http_rewrite1, which serves as purpose on how to rewrite
151 HTTP content with Metaproxy.
153 Use libboost-system if available, because newer versions of libboost-threads
154 requires libboost-system.
156 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
159 --- 1.3.55 2013/04/10
161 zoom: Torus setting: authenticationMode which may hold values "basic"
164 --- 1.3.54 2013/03/27
166 configure: check for Libxslt support in YAZ and rely on definitions
167 from yaz-config, rather than doing own xslt/xml2 checks.
169 Allow timestamp format for log lines to be given with option -m
170 for metaproxy. Similar to yaz-ztest/GFS option -m.
172 Document log category 'line' for log filter.
174 Solr configuration example in etc/config-solr.xml
176 multi: do not mess with request package. For scan and search,
177 database-names were modified and the request package was left with
178 dangling pointers that caused a log filter to fail (request package
179 inspected after multi was invoked).
181 Documentation: fix id of metaproxy-config ref .
183 Documentation: update for USEMARCON support.
185 --- 1.3.53 2013/01/31
187 record_transform: allow OPACXML to OPAC conversion
189 zoom: document content-proxy
191 zoom: document db parm content-{user,password}, torus_url. Also
192 <torus auth_url="..> which makes zoom operate in authenticated mode
195 --- 1.3.52 2012/11/30
197 zoom: fix http://-check. SRU search broken in 1.3.51.
199 --- 1.3.51 2012/11/15
201 zoom: only append http:// for SRU if not already given . Makes it
202 possible to use https-URLs.
204 Use yazpp 1.4 or later due to new ABI.
206 frontend_net: allow max package size to be specified. Controlled by
207 attribute 'max_recv_bytes' of element 'port'.
209 --- 1.3.50 2012/10/29
211 For most generated diagnostics by filters, typically temporary
212 system error, augment addinfo message with filter name.
214 Add support for CentOS 6 packages.
216 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
218 Add man page for metaproxy-config.
220 --- 1.3.49 2012/10/18
222 zoom: new config element passthru. This defines an element set that is
223 passed verbatim to the backend in pz2 mode.
225 auth_simple: allow both idPass and open auth. Also fix SEGV that could
228 --- 1.3.48 2012/10/08
230 z3950_client: fix string handling for init diagnostics in the case where
233 query_rewrite: no charset conversion for error queries. Avoid performing
234 charset conversion for query conversion errors. The resulting Type-1
235 query is invalid in this case.
237 --- 1.3.47 2012/10/04
239 For graceful stop (SIGUSR1), metaproxy will kill children processes.
241 Log when metaproxy is invoked in test mode (-t).
243 Log PID for each log message.
245 multi: combine both NSDs and multiple NSDs into one (diagnostics).
247 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
248 a (backend=target) is appended for each diagnostic so that can be
249 determined the origin of error.
251 multi: hideerrors also in use for present response.
253 Solr example in zoom man page.
255 Fix typo in query_rewrite config example.
257 Log at least first non surrogate diagnostic. Instead of
258 "Z_Records_multipleNSD"
260 multi: Fix check for opt Records in present response. A SEGV could occur
261 if a target did not return records and no diagnostics.
263 --- 1.3.46 2012/09/24
265 Yet another fix for graceful stop.
267 --- 1.3.45 2012/09/12
269 sru_z3950: relay surrogate diagnostics.
271 --- 1.3.44 2012/09/10
273 zoom: Honor extraArgs, strip # in zurl.
275 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
277 zoom: url_recipe allow %{var[reg]} substitutions.
278 It's like ${var[reg]} but does URI component encoding as well.
280 --- 1.3.43 2012/08/22
282 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
283 non-keepalive HTTP sessions.
285 http_file: allow zero size files (bug fix)
287 Fix zoom schema: auth_url is optional
289 --- 1.3.42 2012/08/20
291 zoom: fix un-init memory (could result in SEGV at session close)
293 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
294 and may be used in filters as usual.
296 zoom: authentication via Torus lookup
297 Enabled by new configuration setting: auth_url . If this is defined,
298 the zoom module will contact Torus for auth/IP lookup and that will
299 define realm to be used in session.
301 --- 1.3.41 2012/08/10
303 virt_db: Fix database name - first character we removed by mistake.
304 Bug introduced in 1.3.40.
306 --- 1.3.40 2012/08/06
308 virt_db: Don't use "unix path" as database for Unix sockets.
310 --- 1.3.39 2012/08/02
312 z3950_client: Don't tamper with / in zurl - fixes problems
313 using Unix sockets for backends.
315 session_shared: fix integer overflow problem with hit count.
317 session_shared: avoid long usage of cached queries.
319 zoom: New database argument , torus_url to set URL of Torus
320 record to be fetched.
322 --- 1.3.38 2012/07/04
324 Fixes for 'metaproxy reload' for RPM/Debian packages.
326 zoom: Allow rpn2cql conversion to be augmented with a properties file.
327 Element rpn2cql can be specified per-target for the zoom filter.
329 log: New category "line" which is a single-line log message with
330 most important parts of a HTTP/Z39.50 request/response.
332 --- 1.3.37 2012/06/01
334 frontend_net: add facility to report live statistics about response
335 times and current thread usage. The report is an XML document
336 and is triggered for a specific URL path. This is set by <stat-req>
337 in the configuration of frontend_net. By default this report is
338 disabled (same as empty value for <stat-req>).
340 Fix reload problem in init.d script for RPM/Debian.
341 The '/etc/init.d/metaproxy reload' in some cases would stop but not
342 start metaproxy - effectively stopping the service.
344 Don't display start log message when config testing (-t).
346 zoom: avoid CCL message limit of 1K in ZOOM filter.
348 --- 1.3.36 2012/05/10
350 metaproxy init script reacts to reload which does graceful stop +
351 start and is used by logrorate script.
353 --- 1.3.35 2012/05/09
355 Fixes for Windows compilation.
357 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
358 existing sessions running but terminate the monitor process that is
359 used in keepalive mode.
361 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
362 before. Consistent with 'metaproxy stop' message.
364 zoom: document zoom's proxy_timeout
366 z3950_client: fixup addinfo for init response
368 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
369 "Access to specified database denied" is returned, but only if init
370 response from backend does not carry diagnostics already.
372 multi: relays user info for first rejected target. The other-information
373 field for init response for first rejected target is in common init
374 response. This ensures that some backend init diagnostics are returned to
377 --- 1.3.34 2012/04/25
379 frontend_log: extend logging (when message is given in config).
381 --- 1.3.33 2012/04/25
383 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
385 --- 1.3.32 2012/04/24
387 sru_z3950 filter passes through incoming Z39.50 requests again. Was
388 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
390 --- 1.3.31 2012/04/24
392 zoom: fixes for retry/proxy failover logic. More logging.
394 --- 1.3.30 2012/04/23
396 zoom: return addinfo="proxy failure" for proxy failures. This also
397 changes the scheme for dealing with proxies a bit. zoom now always
398 do proxy check, even if there's no failover. Fortunately, that's not
401 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
402 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
403 generic. We don't know why the init would fail; IP, user, block IP, etc.
404 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
406 zoom: guess if invalid SRU response was an auth failure
408 session_shared: disable session retry by default . Can be enabled by
409 restart="true" in resultset section.
411 --- 1.3.29 2012/04/18
413 zoom: may read cf-proxy's config settings.
414 This reduces manual configuration of the content proxy server host.
415 The ZOOM module will use the old style session.proxyhost if "server"
416 is given (deprecated) and use the new style proxyhost/session if
417 "config_file" is in use.
419 frontend_net: remove incoming requests that can not be handled
420 Requests in queue for filter frontend_net are removed if client
421 closes connection for the session and request is not yet handled.
423 sru_z3950: serialize requests. This is to ensure that pipelined
424 HTTP requests are handled properly.
426 --- 1.3.28 2012/04/04
428 New class, wrbuf, that wraps YAZ' WRBUF.
430 --- 1.3.27 2012/03/30
432 Metaproxy daemon is now running as user "metaproxy". This user is
433 managed by package maintainer scripts. The user information is stored
434 in /etc/metaproxy/metaproxy.user .
436 --- 1.3.26 2012/03/20
438 New filter, sort, that allows sorting of XML records via Z39.50
441 Filter record_transform: USEMarcon support. For example:
442 <retrieval syntax="usmarc">
443 <backend syntax="unimarc" name="F">
444 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
448 Filter multi: empty route pattern uses route as default.
450 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
451 may use the shorter notation
452 <target route="z3950.indexdata.com"/>
454 Filter query_rewrite: use config path to locate XSLT.
456 Filter frontend_net: log statistics.
457 If a custom message element in frontend_net configuration it makes
458 the frontend_net filter produce a log entry whenever an operation
459 is completed. The log is always written using yaz_log with the
460 custom message given, the package ID (session ID) , the time
461 the operation has been active (end-to-end) , the threads currently
462 active/total and the size of the request input/output queues.
464 query_rewrite: charset conversion of query terms.
465 This is an optional feature. Enabled by element <charset> in
466 configuration with attribute 'from' and 'to' that specifies
467 from/to encodings. The default 'from' encoding is UTF-8.
469 Filter record_transform: honor piggyback searches.
471 Filter zoom: re-connect when database is reused.
472 Re-connect is necessary if a connection is lost or a timeout occurs.
473 If not, we'll be seeing zero hits, when we shouldn't.
475 --- 1.3.25 2012/02/29
477 zoom: Change scheme for dealing with content proxy URLs. The module
478 now has its own common XSL transform that is enabled by record_xsl
479 attribute in the configuration. This XSL gets parameter cproxyhost
480 that holds the host for the content proxy session . The genearted-url
481 is created only if urlRecipe is enabled. In previous version default
482 value of urlRecipe was ${md-electronic-url}; it is now empty and
483 disabled by default. Also generated-url no longer includes the content
484 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
487 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
488 connections. Default value is 40 (seconds).
490 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
491 "Malformed query" for syntax errors and related ones; throw
492 Bib-1: 3 "Unsupported search" for everything else. Details from
493 the CCL parser is provided as additional-info.
495 multi: new setting hideerrors that makes multi only relay diagnostics
496 to a client if all backends fail.
498 --- 1.3.24 2012/02/23
500 zoom: empty ccl_map field-mappings disables CCL map.
502 zoom: fix Explain search that could return error if session was
505 --- 1.3.23 2012/02/10
507 zoom: returns Explain records for database IR-Explain---1. The
508 target profile records are converted to Explain records via XSLT.
510 session_shared: make error recovery configurable. Whether a search
511 is restarted on errors or not, is configurable by attribute "restart"
512 in element "resultset" in configuration.
514 session_shared: only relay init for first request. session_shared, for
515 each backend class, now only relays first init request (rather than all).
516 The module only needs to save init response info once. This avoids the
517 need to check for session max.
519 --- 1.3.22 2012/02/02
521 zoom: fix memory leaks.
523 session_shared: maximum number of sessons is configurable. Default
524 value is 100. Result-sets for backends without named result sets are
525 only re-used if databases is identical for a search. This is under the
526 assumption that performance may suffer for those backends when
527 changing the database for each search.
529 multi: combines diagnostics from all backends. All diagnostics from
530 backends are combined into multiple non-surrogate diagnostics; rather
531 than just one diagnostic from first backend.
533 --- 1.3.21 2011/12/27
535 zoom: relay realm to cproxy parameter file.
537 Configuration: Allow filter collection element inside route. This
538 makes it possible to include multiple filters at once.
540 zoom: nocproxy also disables urlRecipe.
542 --- 1.3.20 2011/12/21
544 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
545 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
546 90: "Unsupported direction value".
548 zoom: honor database argument nocproxy. This disables creating a content
549 connector session (for non-CF targets, usually) and also relays nocproxy
550 as database argument to a CF target.
552 --- 1.3.19 2011/12/16
554 zoom: Multiple proxy hosts may be given for proxy rich database
555 parameter. List is comma separated.
557 http_file: decodes URI paths properly. Does not return 404: not found
558 if no prefix are matches. Instead packages are passed on.
560 --- 1.3.18 2011/12/08
562 zoom: content-{user,password,proxy} are passed on to content proxy
563 system and takes precedence over user,password,proxy .
565 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
566 with a log element including log material from children filters. At
567 this point, only the zoom filter uses this log facility. It will
568 eventually be used by other filters as well. In particular it might be
569 useful for this feature to track all filters in used during a search.
571 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
572 and queries as they are manipulated are logged.
574 zoom: extend addinfo with native diagnostics. Diagnostics as received
575 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
576 diagnostics. This indicates both a backend diagnostic and the original
579 zoom: default urlRecipe value is ${md-electronic-url}
581 zoom: target profile setting sruVersion is recognized.
583 --- 1.3.17 2011/11/17
585 zoom: log target profile record fetched (AKA Torus).
587 --- 1.3.16 2011/11/17
589 Change target profile parameter CfSubDb to CfSubDB.
591 --- 1.3.15 2011/11/12
593 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
594 makes sense to the zoom module itself).
596 --- 1.3.14 2011/11/11
598 zoom: realm may be given as part of database.
600 --- 1.3.13 2011/10/26
602 Fix Origin class assigment method; was removd by mistake in 1.3.12.
604 --- 1.3.12 2011/10/26
606 zoom: database args x-name=value are passed through to backend database.
608 SRU filter: user may specify session ID that is passed to log entries
609 that follows. It is specified by using x-session-id in the SRU arguments.
611 zoom: fix null pointer reference which would occur for bad url parameter
612 inside "torus" or if url was not given.
614 --- 1.3.11 2011/09/09
615 Fix bug in filter session_shared where sessions would not expire
616 properly (session ttl). This in turn could make the target close the
617 connection before expected and session_shared would return diagnostic
618 2: system temporarily available.
620 --- 1.3.10 2011/09/09
622 zoom: new target profile setting: sortmap_field. If sortmap_field is given
623 the field is mapped to the value for the sortmap. Values not matching
624 sortmap_field are passed verbatim.
626 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
627 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
628 depending on whether RPN or CQL is actually sent to the target.
632 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
634 zoom: For content proxy authentication is stored in param name
635 "auth", instead of "authentication".
639 zoom: relay schema in SRU mode. Previously recordSchema was not affected
644 zoom: new target profile element literalTransform that holds XSLT
645 (encoded as string) for target. Only if present and non-zero length it is
646 considered present. This takes precedence over transform.
648 Don't rely on trang anymore for Git checkout builds. Configuration in etc
649 will only be properly validated if trang is available. From now on only
650 relax NC files are bundled with the source dist.
652 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
653 component was not detected when it should be.
657 z3950_client: mark non-surrogate diagnostics from backend.
659 zoom: a proxy may be specified for HTTP fetch of target profiles.
663 Honor piggyback. Makes some SRU targets behave that insist on
664 maximumRecords > 0, but also increases performance.
668 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
669 file was not update for libdir/metaproxy4 in version 1.3.2.
673 Change location of Metaproxy modules from libdir/metaproxy to
674 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
675 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
677 New facility to dump APDUs from zoom filter. Enabled by
678 <log apdu="true"/> in the zoom filter configuation.
680 zoom filter bug fix: SRU diagnostics received from backend was
681 not properly converted to Bib-1 diagnostics.
683 Package metaproxy depends on libmetaproxy4, same version.
687 zoom: fix a bug WRT passing authentication parameters to backends.
691 Fixes for windows Makefile.
693 --- 1.2.10 2011/07/25
695 Change major version of metaproxy library from 3 to 4. This in turn
696 makes new package names for Debian and RPM.
700 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
703 zoom: configurable element sets for record transforms.
705 zoom: the target profile based transform is specified by element_transform
706 in element torus of of the ZOOM filter configuration ; default value
707 is "pz2". Target profile based retrieval is specified by element_raw
708 in configuration. It will perform same steps, but omit the XSL transform.
709 Default value is "raw".
711 zoom: element set is omitted if not set in profile. But only if pz2
712 transform is in effect. Previously the default element set was to "F".
714 zoom: For non-CF targets database arguments are parsed. User may supply
715 db,user=myuser&password=mypass for non-CF targets. These values override
716 what's given the authentication from the target profile.
718 session_shared: fix reference to freed memory. Would occur if a search
719 response had non-surrogate diagnostics.
723 Route may be given for each port in frontend_net.
727 Documentation for zoom filter. Local target profiles may be specified.
729 Fixes for zoom filter.
733 First version with zoom filter.
737 Filter z3950_client may be configured to always send a close APDU
738 to backend target when connection/session is closed. This will only
739 happen if close APDU is not already sent. Enabled by configuration
740 for z3950_client (force_close).
742 Filter virt_db and multi: relay close APDU.
744 Filter virt_db and multi: relay init size parameters
745 preferredMessageSize and maximumRecordSize.
747 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
751 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
753 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
754 as determined by configure.
756 RPM: Release includes 'indexdata' name. Use indexdata in release name so
757 this package can be distinguished from other vendors.
761 Fix filter multi: relay idAuthentication parameters.
765 Add metaproxy-config for returning compiler flags, libraries.
769 Fix --with-boost=PREFIX .
773 session_shared: fix use of maintenance thread.
775 Introduce 'start' method for filters and routers. It gets called after
776 configure and after fork, but before processing. This changes API -
777 from libmetaproxy2 to libmetaproxy3.
781 session_shared: ensure backend session is closed if init rejected
784 z3950_client: fix NULL ptr reference that could occur if two clients
785 connected concurrently and if max-sockets was in effect.
789 Fix bug 3497 - Metaproxy unstable while stopping.
791 Fix bug 3495 - SEGV in SRU filter.
795 Filter multi throws diagnostic 'Present Out of Range' when
796 appropriate - rather than returning 0 records.
798 Filter virt_db: fix bad result reuse. Could happen if a result
799 was overriden and a backend did not supported named result sets.
803 Filter log: category access logs diagnostics even if searchStatus
804 or presentStatus is 'success'.
808 The SRU to Z39.50 filter does repeated Z39.50 present requests
809 to fetch all records. Needed when a Z39.50 server returns partial
810 results (due to message size limits).
814 Metaproxy now kills all child processes that are spawned by
815 modules (in case of fork, exec).
819 Debian package now installs /etc/metaproxy/metaproxy.xml which
820 includes all XML files /etc/metaproxy/filters-enabled .
821 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
825 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
826 development package to facilitate 3rd party Metaproxy modules.
828 --- 1.0.23 2010/01/04
830 Filter virt_db: Close backend filter session when Init rejected is received
831 from it (in which case it's not really closed yet). This will ensure we don't
832 run out of resources such as FDs in this case.
834 sru_z3950 filter: Accept any database (including those not listed).
836 --- 1.0.22 2009/12/03
838 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
839 later which means YAZ 3.0.47 or later.
841 --- 1.0.20 2009/11/19
843 For filter virt_db, the database is a glob pattern and the virtual
844 database sections are consulted in the order given.
846 --- 1.0.19 2009/07/08
848 For filter multi, the target (for routing) may be given as a glob-pattern.
850 More documentation for filters virt_db and multi.
852 Update schema to allow for no database in sru_z3950 filter.
854 --- 1.0.18 2009/06/30
856 Added limit filter to put sleep (penalty) for heavy use.
858 Filter frontend_net may be configured to limit the number of new connections
859 from same IP to some value (connect-max).
861 Fixed the load_balance filter.
863 --- 1.0.17 2009/06/16
865 Fix path for metaproxy executable for Debian init.d script.
867 --- 1.0.16 2009/06/10
869 SRU to Z39.50 filter honors x-username and x-password. If only
870 x-username is given that translates to open authentication (Z39.50v2). If
871 both x-username and x-password is present that translates to idPass
872 authentication (Z39.50v3).
874 New facility to change current working directory (-w).
876 Update to upstream skeleton of init.d script. Should fix bug #2619.
878 Filter session_shared now caches records (used to only cache connections
881 Filter session_shared now invalidates a Z39.50 session if a server
882 returns -1 hits. This facility was also part of yazproxy and gets around
883 a bug in Voyager-based Z39.50 servers.
885 --- 1.0.15 2008/11/18
887 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
889 --- 1.0.14 2008/06/09
891 Fixed the value of SRU record schema in searchRetrieve response. It was set
892 to a fixed value of "dc" before.
894 Serialize identical SRU requests. This is useful if HTTP client software
895 fires identical requests against metaproxy.
897 Allow Z39.50 target to be specified for SRU requests by using SRU extra
898 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
899 avoid static configuration. This facility is handled by the sru_z3950 module
900 and the z3950_client module.
902 Allow maximum number of sockets to be used for a Z39.50 client by the
903 use of SRU extra parameter x-max-sockets. This facility is handled by the
904 sru_z3950 module and the z3950_client module.
906 --- 1.0.13.1 2008/02/29
908 Simplified check for Boost libraries.
910 --- 1.0.13 2008/02/29
912 First Debian package.
914 The sru_z9350 filter now recognizes SRU parameter z-target as being
915 a ZURL of the form host/database .
917 Mergetype may be specified for filter 'multi'.
919 --- 1.0.12 2007/09/19
921 Fixed problem in Makefile WRT library specifictions. This could produce
922 linker errors (when they should not happen).
924 Fixed bug #1341: MetaProxy returning different results. Problem was that
925 fix-up of record database did not normalize the database name.
927 Documentation updates for Windows compilation.
929 --- 1.0.11 2007/06/14
931 Fixed problem with logfile being truncated.
933 --- 1.0.10 2007/05/23
935 Fixed bug #1136: Access rights not enforced.
937 Extension for log module. The log category 'access' logs more details.
938 New category 'user-access' added which is simlar to 'access' but adds
939 the Z39.50 user as for all entries in a session.
943 Added support for configurable default/force target/vhost for module Z39.50
948 Implemented filter, session_shared, which optimizes usage of Z39.50
949 sessions and result sets.
951 New filter, record_transform, which converts MARC/XML records.
953 New filter, sru_z3950, which converts SRU to Z39.50 packages.
955 New filter, load_balance, in development.
957 New filter, zeerex_xplain.
959 XML framework for config files started.
961 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
962 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
963 XML config files are checked against RNG and XML Schema's.
965 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
966 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
967 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
968 explain record to YAZ CQL-to-PQF text config file.
972 Added 'timeout' setting for filter frontend_net which specifies the number
973 of seconds a session is idle before it is closed. Default timeout is
978 Database name in records returned set for virt_db/multi filters.
980 Filter session_shared now functional.
982 Log filter can be configured to write to a given file using 'filename'
983 element. Also information category can be specified with 'category'. If
984 filename is omitted, the log filter writes to stdout. See etc/config5.xml
989 Fixed compilation on Windows.
993 Added documentation for the hidenavailable option for the multi filter.
997 Fixed bug #573: Hide errors for individual servers. If the element
998 'hideunavailable' is given in the configuration, individual servers
999 being unavailable are hidden (unless all are unavailable).
1001 Fixed bug #574: Database names are recognised case-sensitively.
1003 Fixed bug #567: Fix up database name in Name-Plus-Record.
1005 Fixed bug #568: Update win/makefile for VS 2005.
1007 Fixed bug #569: Some options throws unknown exception.
1009 --- 1.0.2 2006/04/28
1011 More information about virtual hosts. The 'etc' directory is part of the
1014 --- 1.0.1 2006/04/27
1016 Build instructions for Windows. NMake makefile part of distribution tar.
1018 --- 1.0.0 2006/04/24
1022 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1023 log, multi, query_rewrite, template, virt_db, z3950_client.
1025 Filters in development: session_shared.
