3 sru_z3950: fix facet response (memory corruption) MP-532
5 log: fix crash idPass user is omitted MP-530
9 query_rewrite: pass-thru non Type-1 queries MP-527
11 metaproxy stop (SIGTERM) kills all child processes spanwed by
12 filter (if any) before invoking filter destructors. MP-525
16 http_file: only supports HTTP GET MP-523
18 session_shared: shut down expire thread in destructor
19 This ensures that expire thread is not running after destruction
20 and does bad memory references, etc.
22 frontend_net: fix segfault on startup MP-524
23 Would happen if MP was listening on multiple ports and one
24 of the ports was already in use (and MP would exit).
26 frontend_net: fix memory leak MP-521
27 This leak would occur if all sessions were in use and the input
28 queue was cleared when a client would close connection (socket).
30 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
34 http_rewrite: use local skiplist; fixes memory corruption. MP-520
36 http_client: x-forwarded-for controls X-Forwarded-For presence
37 If x-forwarded-for setting (boolean) is enabled, http_client will
38 generate an X-Forwarded-For header entry which includes existing
39 X-Forwarded-For (if any) and current peer address (immediate client
40 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
41 will not be generated.
43 z3950_client: client_ip controls client-IP presence
44 If client_ip setting (boolean) is enabled, z3950_client will
45 generate a client_ip OID as part of init request which includes
46 previous client_ip (if any) and current peer address (immediate
47 client of Metaproxy). By default client_ip is disabled and client_ip
48 will not be generated.
50 HTTP X-Forwarded-For/Z39.50 Client-IP support
51 virt_db, multi: relays Z39.50 client-IP.
52 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
53 zoom: uses Client-IP or origin address (prefer Client-IP).
54 frontend_net: Strips tcp: from peer address (so that it is no longer
55 printed and stripped in zoom filter).
56 z3950_client: builds client-IP list - combining immediate peer address
57 as returned by COMSTACK and existing client-IP list (if avaiable).
58 The Origin only printes first X-Forwarded address.
62 Log when SIG{TERM,USR1} is received ASAP MP-513
63 Do it in frontend_net event loop rather than in place for metaproxy
64 main, which only exits when all sessions are terminated for SIGUSR1
67 metaproxy-config: quote some RHS values (that might include blanks)
69 Fix leak in sru_z3950 filter - when explain is returned MP-511
71 Allow stylesheet to be given for sru_z3950 filter MP-510
72 This is based on a patch by Sven Porst and the functionality
73 of the YAZ Generic Frontend Server.
75 Allow base attribute in configuration file tags - the attributes are
76 inserted by XInclude usage as mentioned on
77 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
78 and noted in a gist: https://gist.github.com/3551094
80 Package metaproxy provides virtual package metaproxy6 MP-508
81 This allows module packages to depend on a metaproxy server
84 Filter destructors called upon daemon termination MP-505
85 When metaproxy daemon receives SIGTERM the stop method of each filter
86 is called. The stop method existed before, but did not take any
87 arguements (void).. The frontend_net filter can now distinguish
88 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
89 (stop immediately). Note that this changes the API+ABI of Metaproxy
92 zoom: sync up with Pazpar2 WRT authentication handling MP-492
94 Router: use shared_ptr rather than naked one - to avoid leak if an
95 exception is thrown in configure.
99 zoom: Add nocproxy=1 for contentConnector sessions MP-501
101 Doc: mention proper versions; fix link to Boost win binaries.
103 Windows: update for Boost 1.55
105 Windows: avoid warning when using boost::split. Done by defining
106 _SCL_SECURE_NO_WARNINGS for Visual Studio.
108 Fix LSB conformance for /etc/init.d/metaproxy MP-500
109 Debian: add support for /etc/init.d/metaproxy status
111 sort: Add const to Record less than operator in order to compile on
116 session_shared: fix element-set handling in record caching. MP-499
118 document http_rewrite. MP-468
120 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
121 respects the header (which will normally come from the cproxy filter)
125 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
126 RPM was unsable in version 1.4.0.
128 Remove log message about "backend classes". Appeared in version 1.4.0.
132 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
133 with older version from source, but packages now use YAZ 5 that supports
136 sru_z3950: Fix SEGV for decoding invalid SRU requests
137 Incorrect reference to union (was explain response rather than
140 session_shared: match additionalSearchInfo (includes facets). In
141 layman's terms means that means that facets are properly handled
142 by this filter. Eg a change in requested facets will issue new
143 search and facets from exisiting result set are cached.
145 --- 1.3.62 2013/09/11
147 http_rewrite: better handling of <script> content in HTML parser. MP-486
149 http_rewrite: fix threading issue with regex. MP-482
151 bounce: don't use strdup for fixed length content. Error occurred in echo
154 session_shared: expire backend class when no instances left. This
155 means memory clean up, but not really a leak fix.
157 virt_db: fix leak for naked ptr.
159 cql_rpn: use config relative path for cql2rpn file. MP-481
161 Updates for upcoming YAZ 5.
163 --- 1.3.61 2013/08/29
165 New configuration directories ports.d/routes.d for metaproxy
166 configuration. This allows 3rd party packages to install config
167 for ports and new routes. MP-477
169 --- 1.3.60 2013/08/21
171 Fix metaproxy-config --libs to return non-mt over mt libs.
172 The -mt versions do not exist as shared objects and cause
173 linker errors for applications linking with Metaproxy.
174 Problem present in versions 1.3.56 - 1.3.59. MP-475
176 HTML: clean up char checks. Add ptr to HTML parse spec
178 HTML parser stops eating tag when <-char is met MP-473
180 rewrite: do not even compare content types, if we don't have any
181 the regex_match caused a segfault if we had no content-type in the
184 rewrite: within header=... matches only the header value
185 Used to match the whole header line, but we need to use
186 ^$ anchoring for host-relative regexps, and they need to
187 anchor at the ends of the value. MP-470.
189 rewrite: Ruleset functional MP-469
191 --- 1.3.59 2013/07/12
193 session_shared: negotiate init sz parameters.
194 By default, session_shared will honor the paramters given by client.
195 An alternative, but not implemented, algorithm would be to only
196 re-use sessions with same sz parameters. This however, could reduce
197 re-use of sessions a lot. Hence this, simple algorithm instead. The
198 negotiation to a maximum sz values can be enabled by using
199 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
200 in configuration. This will make session_shared send those values
201 to backends and use returned init values in negotaition to
202 client before session_shared.
204 session_shared: resolve result-set references.
205 The reference is substitued with the query for old set if database
206 match and query type is Type-1. If not the reference will issue a
209 sort filter: relays RecordComposition including elementSet in use for
212 http_client: better diagnostics
214 http_client: disables HTTP redirect handling by default.
215 It can be configured with max-redirects in configuration.
217 --- 1.3.58 2013/06/12
219 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
221 --- 1.3.57 2013/06/12
223 Make RouterChain and RouterXML part of public API (libmetaproxy).
225 http_client: honor X-Metaproxy-Proxy as an alternative to
226 the "proxy" configuration. Allows proxy to be set per HTTP request.
228 sru_z3950: For SRU requests recognize x-client prefixes as a way
229 to ingest "database parameters".. The suffix of x-client- serves
230 as database argument name. Multiple may be given. For example:
231 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
232 is turned into Z39.50 database
235 --- 1.3.56 2013/05/27
237 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
239 New filter sd_remove, which replaces surrogate diagnostics with
240 SUTRS records. This filter tries to deal with clients that breaks
241 when receiving surrogate diagnostics.
243 new filter http_client. Same role as z3950_client, but just for
244 HTTP. Allows Metaproxy to operate as a HTTP proxy.
246 New filter http_rewrite1, which serves as purpose on how to rewrite
247 HTTP content with Metaproxy.
249 Use libboost-system if available, because newer versions of libboost-threads
250 requires libboost-system.
252 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
255 --- 1.3.55 2013/04/10
257 zoom: Torus setting: authenticationMode which may hold values "basic"
260 --- 1.3.54 2013/03/27
262 configure: check for Libxslt support in YAZ and rely on definitions
263 from yaz-config, rather than doing own xslt/xml2 checks.
265 Allow timestamp format for log lines to be given with option -m
266 for metaproxy. Similar to yaz-ztest/GFS option -m.
268 Document log category 'line' for log filter.
270 Solr configuration example in etc/config-solr.xml
272 multi: do not mess with request package. For scan and search,
273 database-names were modified and the request package was left with
274 dangling pointers that caused a log filter to fail (request package
275 inspected after multi was invoked).
277 Documentation: fix id of metaproxy-config ref .
279 Documentation: update for USEMARCON support.
281 --- 1.3.53 2013/01/31
283 record_transform: allow OPACXML to OPAC conversion
285 zoom: document content-proxy
287 zoom: document db parm content-{user,password}, torus_url. Also
288 <torus auth_url="..> which makes zoom operate in authenticated mode
291 --- 1.3.52 2012/11/30
293 zoom: fix http://-check. SRU search broken in 1.3.51.
295 --- 1.3.51 2012/11/15
297 zoom: only append http:// for SRU if not already given . Makes it
298 possible to use https-URLs.
300 Use yazpp 1.4 or later due to new ABI.
302 frontend_net: allow max package size to be specified. Controlled by
303 attribute 'max_recv_bytes' of element 'port'.
305 --- 1.3.50 2012/10/29
307 For most generated diagnostics by filters, typically temporary
308 system error, augment addinfo message with filter name.
310 Add support for CentOS 6 packages.
312 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
314 Add man page for metaproxy-config.
316 --- 1.3.49 2012/10/18
318 zoom: new config element passthru. This defines an element set that is
319 passed verbatim to the backend in pz2 mode.
321 auth_simple: allow both idPass and open auth. Also fix SEGV that could
324 --- 1.3.48 2012/10/08
326 z3950_client: fix string handling for init diagnostics in the case where
329 query_rewrite: no charset conversion for error queries. Avoid performing
330 charset conversion for query conversion errors. The resulting Type-1
331 query is invalid in this case.
333 --- 1.3.47 2012/10/04
335 For graceful stop (SIGUSR1), metaproxy will kill children processes.
337 Log when metaproxy is invoked in test mode (-t).
339 Log PID for each log message.
341 multi: combine both NSDs and multiple NSDs into one (diagnostics).
343 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
344 a (backend=target) is appended for each diagnostic so that can be
345 determined the origin of error.
347 multi: hideerrors also in use for present response.
349 Solr example in zoom man page.
351 Fix typo in query_rewrite config example.
353 Log at least first non surrogate diagnostic. Instead of
354 "Z_Records_multipleNSD"
356 multi: Fix check for opt Records in present response. A SEGV could occur
357 if a target did not return records and no diagnostics.
359 --- 1.3.46 2012/09/24
361 Yet another fix for graceful stop.
363 --- 1.3.45 2012/09/12
365 sru_z3950: relay surrogate diagnostics.
367 --- 1.3.44 2012/09/10
369 zoom: Honor extraArgs, strip # in zurl.
371 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
373 zoom: url_recipe allow %{var[reg]} substitutions.
374 It's like ${var[reg]} but does URI component encoding as well.
376 --- 1.3.43 2012/08/22
378 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
379 non-keepalive HTTP sessions.
381 http_file: allow zero size files (bug fix)
383 Fix zoom schema: auth_url is optional
385 --- 1.3.42 2012/08/20
387 zoom: fix un-init memory (could result in SEGV at session close)
389 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
390 and may be used in filters as usual.
392 zoom: authentication via Torus lookup
393 Enabled by new configuration setting: auth_url . If this is defined,
394 the zoom module will contact Torus for auth/IP lookup and that will
395 define realm to be used in session.
397 --- 1.3.41 2012/08/10
399 virt_db: Fix database name - first character we removed by mistake.
400 Bug introduced in 1.3.40.
402 --- 1.3.40 2012/08/06
404 virt_db: Don't use "unix path" as database for Unix sockets.
406 --- 1.3.39 2012/08/02
408 z3950_client: Don't tamper with / in zurl - fixes problems
409 using Unix sockets for backends.
411 session_shared: fix integer overflow problem with hit count.
413 session_shared: avoid long usage of cached queries.
415 zoom: New database argument , torus_url to set URL of Torus
416 record to be fetched.
418 --- 1.3.38 2012/07/04
420 Fixes for 'metaproxy reload' for RPM/Debian packages.
422 zoom: Allow rpn2cql conversion to be augmented with a properties file.
423 Element rpn2cql can be specified per-target for the zoom filter.
425 log: New category "line" which is a single-line log message with
426 most important parts of a HTTP/Z39.50 request/response.
428 --- 1.3.37 2012/06/01
430 frontend_net: add facility to report live statistics about response
431 times and current thread usage. The report is an XML document
432 and is triggered for a specific URL path. This is set by <stat-req>
433 in the configuration of frontend_net. By default this report is
434 disabled (same as empty value for <stat-req>).
436 Fix reload problem in init.d script for RPM/Debian.
437 The '/etc/init.d/metaproxy reload' in some cases would stop but not
438 start metaproxy - effectively stopping the service.
440 Don't display start log message when config testing (-t).
442 zoom: avoid CCL message limit of 1K in ZOOM filter.
444 --- 1.3.36 2012/05/10
446 metaproxy init script reacts to reload which does graceful stop +
447 start and is used by logrorate script.
449 --- 1.3.35 2012/05/09
451 Fixes for Windows compilation.
453 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
454 existing sessions running but terminate the monitor process that is
455 used in keepalive mode.
457 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
458 before. Consistent with 'metaproxy stop' message.
460 zoom: document zoom's proxy_timeout
462 z3950_client: fixup addinfo for init response
464 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
465 "Access to specified database denied" is returned, but only if init
466 response from backend does not carry diagnostics already.
468 multi: relays user info for first rejected target. The other-information
469 field for init response for first rejected target is in common init
470 response. This ensures that some backend init diagnostics are returned to
473 --- 1.3.34 2012/04/25
475 frontend_log: extend logging (when message is given in config).
477 --- 1.3.33 2012/04/25
479 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
481 --- 1.3.32 2012/04/24
483 sru_z3950 filter passes through incoming Z39.50 requests again. Was
484 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
486 --- 1.3.31 2012/04/24
488 zoom: fixes for retry/proxy failover logic. More logging.
490 --- 1.3.30 2012/04/23
492 zoom: return addinfo="proxy failure" for proxy failures. This also
493 changes the scheme for dealing with proxies a bit. zoom now always
494 do proxy check, even if there's no failover. Fortunately, that's not
497 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
498 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
499 generic. We don't know why the init would fail; IP, user, block IP, etc.
500 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
502 zoom: guess if invalid SRU response was an auth failure
504 session_shared: disable session retry by default . Can be enabled by
505 restart="true" in resultset section.
507 --- 1.3.29 2012/04/18
509 zoom: may read cf-proxy's config settings.
510 This reduces manual configuration of the content proxy server host.
511 The ZOOM module will use the old style session.proxyhost if "server"
512 is given (deprecated) and use the new style proxyhost/session if
513 "config_file" is in use.
515 frontend_net: remove incoming requests that can not be handled
516 Requests in queue for filter frontend_net are removed if client
517 closes connection for the session and request is not yet handled.
519 sru_z3950: serialize requests. This is to ensure that pipelined
520 HTTP requests are handled properly.
522 --- 1.3.28 2012/04/04
524 New class, wrbuf, that wraps YAZ' WRBUF.
526 --- 1.3.27 2012/03/30
528 Metaproxy daemon is now running as user "metaproxy". This user is
529 managed by package maintainer scripts. The user information is stored
530 in /etc/metaproxy/metaproxy.user .
532 --- 1.3.26 2012/03/20
534 New filter, sort, that allows sorting of XML records via Z39.50
537 Filter record_transform: USEMarcon support. For example:
538 <retrieval syntax="usmarc">
539 <backend syntax="unimarc" name="F">
540 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
544 Filter multi: empty route pattern uses route as default.
546 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
547 may use the shorter notation
548 <target route="z3950.indexdata.com"/>
550 Filter query_rewrite: use config path to locate XSLT.
552 Filter frontend_net: log statistics.
553 If a custom message element in frontend_net configuration it makes
554 the frontend_net filter produce a log entry whenever an operation
555 is completed. The log is always written using yaz_log with the
556 custom message given, the package ID (session ID) , the time
557 the operation has been active (end-to-end) , the threads currently
558 active/total and the size of the request input/output queues.
560 query_rewrite: charset conversion of query terms.
561 This is an optional feature. Enabled by element <charset> in
562 configuration with attribute 'from' and 'to' that specifies
563 from/to encodings. The default 'from' encoding is UTF-8.
565 Filter record_transform: honor piggyback searches.
567 Filter zoom: re-connect when database is reused.
568 Re-connect is necessary if a connection is lost or a timeout occurs.
569 If not, we'll be seeing zero hits, when we shouldn't.
571 --- 1.3.25 2012/02/29
573 zoom: Change scheme for dealing with content proxy URLs. The module
574 now has its own common XSL transform that is enabled by record_xsl
575 attribute in the configuration. This XSL gets parameter cproxyhost
576 that holds the host for the content proxy session . The genearted-url
577 is created only if urlRecipe is enabled. In previous version default
578 value of urlRecipe was ${md-electronic-url}; it is now empty and
579 disabled by default. Also generated-url no longer includes the content
580 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
583 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
584 connections. Default value is 40 (seconds).
586 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
587 "Malformed query" for syntax errors and related ones; throw
588 Bib-1: 3 "Unsupported search" for everything else. Details from
589 the CCL parser is provided as additional-info.
591 multi: new setting hideerrors that makes multi only relay diagnostics
592 to a client if all backends fail.
594 --- 1.3.24 2012/02/23
596 zoom: empty ccl_map field-mappings disables CCL map.
598 zoom: fix Explain search that could return error if session was
601 --- 1.3.23 2012/02/10
603 zoom: returns Explain records for database IR-Explain---1. The
604 target profile records are converted to Explain records via XSLT.
606 session_shared: make error recovery configurable. Whether a search
607 is restarted on errors or not, is configurable by attribute "restart"
608 in element "resultset" in configuration.
610 session_shared: only relay init for first request. session_shared, for
611 each backend class, now only relays first init request (rather than all).
612 The module only needs to save init response info once. This avoids the
613 need to check for session max.
615 --- 1.3.22 2012/02/02
617 zoom: fix memory leaks.
619 session_shared: maximum number of sessons is configurable. Default
620 value is 100. Result-sets for backends without named result sets are
621 only re-used if databases is identical for a search. This is under the
622 assumption that performance may suffer for those backends when
623 changing the database for each search.
625 multi: combines diagnostics from all backends. All diagnostics from
626 backends are combined into multiple non-surrogate diagnostics; rather
627 than just one diagnostic from first backend.
629 --- 1.3.21 2011/12/27
631 zoom: relay realm to cproxy parameter file.
633 Configuration: Allow filter collection element inside route. This
634 makes it possible to include multiple filters at once.
636 zoom: nocproxy also disables urlRecipe.
638 --- 1.3.20 2011/12/21
640 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
641 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
642 90: "Unsupported direction value".
644 zoom: honor database argument nocproxy. This disables creating a content
645 connector session (for non-CF targets, usually) and also relays nocproxy
646 as database argument to a CF target.
648 --- 1.3.19 2011/12/16
650 zoom: Multiple proxy hosts may be given for proxy rich database
651 parameter. List is comma separated.
653 http_file: decodes URI paths properly. Does not return 404: not found
654 if no prefix are matches. Instead packages are passed on.
656 --- 1.3.18 2011/12/08
658 zoom: content-{user,password,proxy} are passed on to content proxy
659 system and takes precedence over user,password,proxy .
661 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
662 with a log element including log material from children filters. At
663 this point, only the zoom filter uses this log facility. It will
664 eventually be used by other filters as well. In particular it might be
665 useful for this feature to track all filters in used during a search.
667 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
668 and queries as they are manipulated are logged.
670 zoom: extend addinfo with native diagnostics. Diagnostics as received
671 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
672 diagnostics. This indicates both a backend diagnostic and the original
675 zoom: default urlRecipe value is ${md-electronic-url}
677 zoom: target profile setting sruVersion is recognized.
679 --- 1.3.17 2011/11/17
681 zoom: log target profile record fetched (AKA Torus).
683 --- 1.3.16 2011/11/17
685 Change target profile parameter CfSubDb to CfSubDB.
687 --- 1.3.15 2011/11/12
689 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
690 makes sense to the zoom module itself).
692 --- 1.3.14 2011/11/11
694 zoom: realm may be given as part of database.
696 --- 1.3.13 2011/10/26
698 Fix Origin class assigment method; was removd by mistake in 1.3.12.
700 --- 1.3.12 2011/10/26
702 zoom: database args x-name=value are passed through to backend database.
704 SRU filter: user may specify session ID that is passed to log entries
705 that follows. It is specified by using x-session-id in the SRU arguments.
707 zoom: fix null pointer reference which would occur for bad url parameter
708 inside "torus" or if url was not given.
710 --- 1.3.11 2011/09/09
711 Fix bug in filter session_shared where sessions would not expire
712 properly (session ttl). This in turn could make the target close the
713 connection before expected and session_shared would return diagnostic
714 2: system temporarily available.
716 --- 1.3.10 2011/09/09
718 zoom: new target profile setting: sortmap_field. If sortmap_field is given
719 the field is mapped to the value for the sortmap. Values not matching
720 sortmap_field are passed verbatim.
722 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
723 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
724 depending on whether RPN or CQL is actually sent to the target.
728 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
730 zoom: For content proxy authentication is stored in param name
731 "auth", instead of "authentication".
735 zoom: relay schema in SRU mode. Previously recordSchema was not affected
740 zoom: new target profile element literalTransform that holds XSLT
741 (encoded as string) for target. Only if present and non-zero length it is
742 considered present. This takes precedence over transform.
744 Don't rely on trang anymore for Git checkout builds. Configuration in etc
745 will only be properly validated if trang is available. From now on only
746 relax NC files are bundled with the source dist.
748 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
749 component was not detected when it should be.
753 z3950_client: mark non-surrogate diagnostics from backend.
755 zoom: a proxy may be specified for HTTP fetch of target profiles.
759 Honor piggyback. Makes some SRU targets behave that insist on
760 maximumRecords > 0, but also increases performance.
764 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
765 file was not update for libdir/metaproxy4 in version 1.3.2.
769 Change location of Metaproxy modules from libdir/metaproxy to
770 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
771 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
773 New facility to dump APDUs from zoom filter. Enabled by
774 <log apdu="true"/> in the zoom filter configuation.
776 zoom filter bug fix: SRU diagnostics received from backend was
777 not properly converted to Bib-1 diagnostics.
779 Package metaproxy depends on libmetaproxy4, same version.
783 zoom: fix a bug WRT passing authentication parameters to backends.
787 Fixes for windows Makefile.
789 --- 1.2.10 2011/07/25
791 Change major version of metaproxy library from 3 to 4. This in turn
792 makes new package names for Debian and RPM.
796 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
799 zoom: configurable element sets for record transforms.
801 zoom: the target profile based transform is specified by element_transform
802 in element torus of of the ZOOM filter configuration ; default value
803 is "pz2". Target profile based retrieval is specified by element_raw
804 in configuration. It will perform same steps, but omit the XSL transform.
805 Default value is "raw".
807 zoom: element set is omitted if not set in profile. But only if pz2
808 transform is in effect. Previously the default element set was to "F".
810 zoom: For non-CF targets database arguments are parsed. User may supply
811 db,user=myuser&password=mypass for non-CF targets. These values override
812 what's given the authentication from the target profile.
814 session_shared: fix reference to freed memory. Would occur if a search
815 response had non-surrogate diagnostics.
819 Route may be given for each port in frontend_net.
823 Documentation for zoom filter. Local target profiles may be specified.
825 Fixes for zoom filter.
829 First version with zoom filter.
833 Filter z3950_client may be configured to always send a close APDU
834 to backend target when connection/session is closed. This will only
835 happen if close APDU is not already sent. Enabled by configuration
836 for z3950_client (force_close).
838 Filter virt_db and multi: relay close APDU.
840 Filter virt_db and multi: relay init size parameters
841 preferredMessageSize and maximumRecordSize.
843 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
847 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
849 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
850 as determined by configure.
852 RPM: Release includes 'indexdata' name. Use indexdata in release name so
853 this package can be distinguished from other vendors.
857 Fix filter multi: relay idAuthentication parameters.
861 Add metaproxy-config for returning compiler flags, libraries.
865 Fix --with-boost=PREFIX .
869 session_shared: fix use of maintenance thread.
871 Introduce 'start' method for filters and routers. It gets called after
872 configure and after fork, but before processing. This changes API -
873 from libmetaproxy2 to libmetaproxy3.
877 session_shared: ensure backend session is closed if init rejected
880 z3950_client: fix NULL ptr reference that could occur if two clients
881 connected concurrently and if max-sockets was in effect.
885 Fix bug 3497 - Metaproxy unstable while stopping.
887 Fix bug 3495 - SEGV in SRU filter.
891 Filter multi throws diagnostic 'Present Out of Range' when
892 appropriate - rather than returning 0 records.
894 Filter virt_db: fix bad result reuse. Could happen if a result
895 was overriden and a backend did not supported named result sets.
899 Filter log: category access logs diagnostics even if searchStatus
900 or presentStatus is 'success'.
904 The SRU to Z39.50 filter does repeated Z39.50 present requests
905 to fetch all records. Needed when a Z39.50 server returns partial
906 results (due to message size limits).
910 Metaproxy now kills all child processes that are spawned by
911 modules (in case of fork, exec).
915 Debian package now installs /etc/metaproxy/metaproxy.xml which
916 includes all XML files /etc/metaproxy/filters-enabled .
917 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
921 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
922 development package to facilitate 3rd party Metaproxy modules.
924 --- 1.0.23 2010/01/04
926 Filter virt_db: Close backend filter session when Init rejected is received
927 from it (in which case it's not really closed yet). This will ensure we don't
928 run out of resources such as FDs in this case.
930 sru_z3950 filter: Accept any database (including those not listed).
932 --- 1.0.22 2009/12/03
934 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
935 later which means YAZ 3.0.47 or later.
937 --- 1.0.20 2009/11/19
939 For filter virt_db, the database is a glob pattern and the virtual
940 database sections are consulted in the order given.
942 --- 1.0.19 2009/07/08
944 For filter multi, the target (for routing) may be given as a glob-pattern.
946 More documentation for filters virt_db and multi.
948 Update schema to allow for no database in sru_z3950 filter.
950 --- 1.0.18 2009/06/30
952 Added limit filter to put sleep (penalty) for heavy use.
954 Filter frontend_net may be configured to limit the number of new connections
955 from same IP to some value (connect-max).
957 Fixed the load_balance filter.
959 --- 1.0.17 2009/06/16
961 Fix path for metaproxy executable for Debian init.d script.
963 --- 1.0.16 2009/06/10
965 SRU to Z39.50 filter honors x-username and x-password. If only
966 x-username is given that translates to open authentication (Z39.50v2). If
967 both x-username and x-password is present that translates to idPass
968 authentication (Z39.50v3).
970 New facility to change current working directory (-w).
972 Update to upstream skeleton of init.d script. Should fix bug #2619.
974 Filter session_shared now caches records (used to only cache connections
977 Filter session_shared now invalidates a Z39.50 session if a server
978 returns -1 hits. This facility was also part of yazproxy and gets around
979 a bug in Voyager-based Z39.50 servers.
981 --- 1.0.15 2008/11/18
983 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
985 --- 1.0.14 2008/06/09
987 Fixed the value of SRU record schema in searchRetrieve response. It was set
988 to a fixed value of "dc" before.
990 Serialize identical SRU requests. This is useful if HTTP client software
991 fires identical requests against metaproxy.
993 Allow Z39.50 target to be specified for SRU requests by using SRU extra
994 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
995 avoid static configuration. This facility is handled by the sru_z3950 module
996 and the z3950_client module.
998 Allow maximum number of sockets to be used for a Z39.50 client by the
999 use of SRU extra parameter x-max-sockets. This facility is handled by the
1000 sru_z3950 module and the z3950_client module.
1002 --- 1.0.13.1 2008/02/29
1004 Simplified check for Boost libraries.
1006 --- 1.0.13 2008/02/29
1008 First Debian package.
1010 The sru_z9350 filter now recognizes SRU parameter z-target as being
1011 a ZURL of the form host/database .
1013 Mergetype may be specified for filter 'multi'.
1015 --- 1.0.12 2007/09/19
1017 Fixed problem in Makefile WRT library specifictions. This could produce
1018 linker errors (when they should not happen).
1020 Fixed bug #1341: MetaProxy returning different results. Problem was that
1021 fix-up of record database did not normalize the database name.
1023 Documentation updates for Windows compilation.
1025 --- 1.0.11 2007/06/14
1027 Fixed problem with logfile being truncated.
1029 --- 1.0.10 2007/05/23
1031 Fixed bug #1136: Access rights not enforced.
1033 Extension for log module. The log category 'access' logs more details.
1034 New category 'user-access' added which is simlar to 'access' but adds
1035 the Z39.50 user as for all entries in a session.
1039 Added support for configurable default/force target/vhost for module Z39.50
1042 --- 1.0.8 2007/01/25
1044 Implemented filter, session_shared, which optimizes usage of Z39.50
1045 sessions and result sets.
1047 New filter, record_transform, which converts MARC/XML records.
1049 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1051 New filter, load_balance, in development.
1053 New filter, zeerex_xplain.
1055 XML framework for config files started.
1057 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1058 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1059 XML config files are checked against RNG and XML Schema's.
1061 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1062 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1063 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1064 explain record to YAZ CQL-to-PQF text config file.
1066 --- 1.0.7 2006/11/07
1068 Added 'timeout' setting for filter frontend_net which specifies the number
1069 of seconds a session is idle before it is closed. Default timeout is
1072 --- 1.0.6 2006/07/07
1074 Database name in records returned set for virt_db/multi filters.
1076 Filter session_shared now functional.
1078 Log filter can be configured to write to a given file using 'filename'
1079 element. Also information category can be specified with 'category'. If
1080 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1083 --- 1.0.5 2006/05/16
1085 Fixed compilation on Windows.
1087 --- 1.0.4 2006/05/16
1089 Added documentation for the hidenavailable option for the multi filter.
1091 --- 1.0.3 2006/05/16
1093 Fixed bug #573: Hide errors for individual servers. If the element
1094 'hideunavailable' is given in the configuration, individual servers
1095 being unavailable are hidden (unless all are unavailable).
1097 Fixed bug #574: Database names are recognised case-sensitively.
1099 Fixed bug #567: Fix up database name in Name-Plus-Record.
1101 Fixed bug #568: Update win/makefile for VS 2005.
1103 Fixed bug #569: Some options throws unknown exception.
1105 --- 1.0.2 2006/04/28
1107 More information about virtual hosts. The 'etc' directory is part of the
1110 --- 1.0.1 2006/04/27
1112 Build instructions for Windows. NMake makefile part of distribution tar.
1114 --- 1.0.0 2006/04/24
1118 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1119 log, multi, query_rewrite, template, virt_db, z3950_client.
1121 Filters in development: session_shared.
1123 Pseudo-filters: template, dl
