3 Build packages for Ubuntu Trusty Tahr 14.04 LTS
5 sort: crash / invalid_read in filter sort MP-541
7 sru_z3950: facet should be stored in additionalSearchInfo MP-533
9 doc: fix missing man pages MP-542
11 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
13 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
17 sru_z3950: fix facet response (memory corruption) MP-532
19 log: fix crash idPass user is omitted MP-530
23 query_rewrite: pass-thru non Type-1 queries MP-527
25 metaproxy stop (SIGTERM) kills all child processes spanwed by
26 filter (if any) before invoking filter destructors. MP-525
30 http_file: only supports HTTP GET MP-523
32 session_shared: shut down expire thread in destructor
33 This ensures that expire thread is not running after destruction
34 and does bad memory references, etc.
36 frontend_net: fix segfault on startup MP-524
37 Would happen if MP was listening on multiple ports and one
38 of the ports was already in use (and MP would exit).
40 frontend_net: fix memory leak MP-521
41 This leak would occur if all sessions were in use and the input
42 queue was cleared when a client would close connection (socket).
44 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
48 http_rewrite: use local skiplist; fixes memory corruption. MP-520
50 http_client: x-forwarded-for controls X-Forwarded-For presence
51 If x-forwarded-for setting (boolean) is enabled, http_client will
52 generate an X-Forwarded-For header entry which includes existing
53 X-Forwarded-For (if any) and current peer address (immediate client
54 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
55 will not be generated.
57 z3950_client: client_ip controls client-IP presence
58 If client_ip setting (boolean) is enabled, z3950_client will
59 generate a client_ip OID as part of init request which includes
60 previous client_ip (if any) and current peer address (immediate
61 client of Metaproxy). By default client_ip is disabled and client_ip
62 will not be generated.
64 HTTP X-Forwarded-For/Z39.50 Client-IP support
65 virt_db, multi: relays Z39.50 client-IP.
66 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
67 zoom: uses Client-IP or origin address (prefer Client-IP).
68 frontend_net: Strips tcp: from peer address (so that it is no longer
69 printed and stripped in zoom filter).
70 z3950_client: builds client-IP list - combining immediate peer address
71 as returned by COMSTACK and existing client-IP list (if avaiable).
72 The Origin only printes first X-Forwarded address.
76 Log when SIG{TERM,USR1} is received ASAP MP-513
77 Do it in frontend_net event loop rather than in place for metaproxy
78 main, which only exits when all sessions are terminated for SIGUSR1
81 metaproxy-config: quote some RHS values (that might include blanks)
83 Fix leak in sru_z3950 filter - when explain is returned MP-511
85 Allow stylesheet to be given for sru_z3950 filter MP-510
86 This is based on a patch by Sven Porst and the functionality
87 of the YAZ Generic Frontend Server.
89 Allow base attribute in configuration file tags - the attributes are
90 inserted by XInclude usage as mentioned on
91 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
92 and noted in a gist: https://gist.github.com/3551094
94 Package metaproxy provides virtual package metaproxy6 MP-508
95 This allows module packages to depend on a metaproxy server
98 Filter destructors called upon daemon termination MP-505
99 When metaproxy daemon receives SIGTERM the stop method of each filter
100 is called. The stop method existed before, but did not take any
101 arguements (void).. The frontend_net filter can now distinguish
102 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
103 (stop immediately). Note that this changes the API+ABI of Metaproxy
106 zoom: sync up with Pazpar2 WRT authentication handling MP-492
108 Router: use shared_ptr rather than naked one - to avoid leak if an
109 exception is thrown in configure.
113 zoom: Add nocproxy=1 for contentConnector sessions MP-501
115 Doc: mention proper versions; fix link to Boost win binaries.
117 Windows: update for Boost 1.55
119 Windows: avoid warning when using boost::split. Done by defining
120 _SCL_SECURE_NO_WARNINGS for Visual Studio.
122 Fix LSB conformance for /etc/init.d/metaproxy MP-500
123 Debian: add support for /etc/init.d/metaproxy status
125 sort: Add const to Record less than operator in order to compile on
130 session_shared: fix element-set handling in record caching. MP-499
132 document http_rewrite. MP-468
134 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
135 respects the header (which will normally come from the cproxy filter)
139 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
140 RPM was unsable in version 1.4.0.
142 Remove log message about "backend classes". Appeared in version 1.4.0.
146 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
147 with older version from source, but packages now use YAZ 5 that supports
150 sru_z3950: Fix SEGV for decoding invalid SRU requests
151 Incorrect reference to union (was explain response rather than
154 session_shared: match additionalSearchInfo (includes facets). In
155 layman's terms means that means that facets are properly handled
156 by this filter. Eg a change in requested facets will issue new
157 search and facets from exisiting result set are cached.
159 --- 1.3.62 2013/09/11
161 http_rewrite: better handling of <script> content in HTML parser. MP-486
163 http_rewrite: fix threading issue with regex. MP-482
165 bounce: don't use strdup for fixed length content. Error occurred in echo
168 session_shared: expire backend class when no instances left. This
169 means memory clean up, but not really a leak fix.
171 virt_db: fix leak for naked ptr.
173 cql_rpn: use config relative path for cql2rpn file. MP-481
175 Updates for upcoming YAZ 5.
177 --- 1.3.61 2013/08/29
179 New configuration directories ports.d/routes.d for metaproxy
180 configuration. This allows 3rd party packages to install config
181 for ports and new routes. MP-477
183 --- 1.3.60 2013/08/21
185 Fix metaproxy-config --libs to return non-mt over mt libs.
186 The -mt versions do not exist as shared objects and cause
187 linker errors for applications linking with Metaproxy.
188 Problem present in versions 1.3.56 - 1.3.59. MP-475
190 HTML: clean up char checks. Add ptr to HTML parse spec
192 HTML parser stops eating tag when <-char is met MP-473
194 rewrite: do not even compare content types, if we don't have any
195 the regex_match caused a segfault if we had no content-type in the
198 rewrite: within header=... matches only the header value
199 Used to match the whole header line, but we need to use
200 ^$ anchoring for host-relative regexps, and they need to
201 anchor at the ends of the value. MP-470.
203 rewrite: Ruleset functional MP-469
205 --- 1.3.59 2013/07/12
207 session_shared: negotiate init sz parameters.
208 By default, session_shared will honor the paramters given by client.
209 An alternative, but not implemented, algorithm would be to only
210 re-use sessions with same sz parameters. This however, could reduce
211 re-use of sessions a lot. Hence this, simple algorithm instead. The
212 negotiation to a maximum sz values can be enabled by using
213 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
214 in configuration. This will make session_shared send those values
215 to backends and use returned init values in negotaition to
216 client before session_shared.
218 session_shared: resolve result-set references.
219 The reference is substitued with the query for old set if database
220 match and query type is Type-1. If not the reference will issue a
223 sort filter: relays RecordComposition including elementSet in use for
226 http_client: better diagnostics
228 http_client: disables HTTP redirect handling by default.
229 It can be configured with max-redirects in configuration.
231 --- 1.3.58 2013/06/12
233 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
235 --- 1.3.57 2013/06/12
237 Make RouterChain and RouterXML part of public API (libmetaproxy).
239 http_client: honor X-Metaproxy-Proxy as an alternative to
240 the "proxy" configuration. Allows proxy to be set per HTTP request.
242 sru_z3950: For SRU requests recognize x-client prefixes as a way
243 to ingest "database parameters".. The suffix of x-client- serves
244 as database argument name. Multiple may be given. For example:
245 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
246 is turned into Z39.50 database
249 --- 1.3.56 2013/05/27
251 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
253 New filter sd_remove, which replaces surrogate diagnostics with
254 SUTRS records. This filter tries to deal with clients that breaks
255 when receiving surrogate diagnostics.
257 new filter http_client. Same role as z3950_client, but just for
258 HTTP. Allows Metaproxy to operate as a HTTP proxy.
260 New filter http_rewrite1, which serves as purpose on how to rewrite
261 HTTP content with Metaproxy.
263 Use libboost-system if available, because newer versions of libboost-threads
264 requires libboost-system.
266 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
269 --- 1.3.55 2013/04/10
271 zoom: Torus setting: authenticationMode which may hold values "basic"
274 --- 1.3.54 2013/03/27
276 configure: check for Libxslt support in YAZ and rely on definitions
277 from yaz-config, rather than doing own xslt/xml2 checks.
279 Allow timestamp format for log lines to be given with option -m
280 for metaproxy. Similar to yaz-ztest/GFS option -m.
282 Document log category 'line' for log filter.
284 Solr configuration example in etc/config-solr.xml
286 multi: do not mess with request package. For scan and search,
287 database-names were modified and the request package was left with
288 dangling pointers that caused a log filter to fail (request package
289 inspected after multi was invoked).
291 Documentation: fix id of metaproxy-config ref .
293 Documentation: update for USEMARCON support.
295 --- 1.3.53 2013/01/31
297 record_transform: allow OPACXML to OPAC conversion
299 zoom: document content-proxy
301 zoom: document db parm content-{user,password}, torus_url. Also
302 <torus auth_url="..> which makes zoom operate in authenticated mode
305 --- 1.3.52 2012/11/30
307 zoom: fix http://-check. SRU search broken in 1.3.51.
309 --- 1.3.51 2012/11/15
311 zoom: only append http:// for SRU if not already given . Makes it
312 possible to use https-URLs.
314 Use yazpp 1.4 or later due to new ABI.
316 frontend_net: allow max package size to be specified. Controlled by
317 attribute 'max_recv_bytes' of element 'port'.
319 --- 1.3.50 2012/10/29
321 For most generated diagnostics by filters, typically temporary
322 system error, augment addinfo message with filter name.
324 Add support for CentOS 6 packages.
326 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
328 Add man page for metaproxy-config.
330 --- 1.3.49 2012/10/18
332 zoom: new config element passthru. This defines an element set that is
333 passed verbatim to the backend in pz2 mode.
335 auth_simple: allow both idPass and open auth. Also fix SEGV that could
338 --- 1.3.48 2012/10/08
340 z3950_client: fix string handling for init diagnostics in the case where
343 query_rewrite: no charset conversion for error queries. Avoid performing
344 charset conversion for query conversion errors. The resulting Type-1
345 query is invalid in this case.
347 --- 1.3.47 2012/10/04
349 For graceful stop (SIGUSR1), metaproxy will kill children processes.
351 Log when metaproxy is invoked in test mode (-t).
353 Log PID for each log message.
355 multi: combine both NSDs and multiple NSDs into one (diagnostics).
357 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
358 a (backend=target) is appended for each diagnostic so that can be
359 determined the origin of error.
361 multi: hideerrors also in use for present response.
363 Solr example in zoom man page.
365 Fix typo in query_rewrite config example.
367 Log at least first non surrogate diagnostic. Instead of
368 "Z_Records_multipleNSD"
370 multi: Fix check for opt Records in present response. A SEGV could occur
371 if a target did not return records and no diagnostics.
373 --- 1.3.46 2012/09/24
375 Yet another fix for graceful stop.
377 --- 1.3.45 2012/09/12
379 sru_z3950: relay surrogate diagnostics.
381 --- 1.3.44 2012/09/10
383 zoom: Honor extraArgs, strip # in zurl.
385 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
387 zoom: url_recipe allow %{var[reg]} substitutions.
388 It's like ${var[reg]} but does URI component encoding as well.
390 --- 1.3.43 2012/08/22
392 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
393 non-keepalive HTTP sessions.
395 http_file: allow zero size files (bug fix)
397 Fix zoom schema: auth_url is optional
399 --- 1.3.42 2012/08/20
401 zoom: fix un-init memory (could result in SEGV at session close)
403 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
404 and may be used in filters as usual.
406 zoom: authentication via Torus lookup
407 Enabled by new configuration setting: auth_url . If this is defined,
408 the zoom module will contact Torus for auth/IP lookup and that will
409 define realm to be used in session.
411 --- 1.3.41 2012/08/10
413 virt_db: Fix database name - first character we removed by mistake.
414 Bug introduced in 1.3.40.
416 --- 1.3.40 2012/08/06
418 virt_db: Don't use "unix path" as database for Unix sockets.
420 --- 1.3.39 2012/08/02
422 z3950_client: Don't tamper with / in zurl - fixes problems
423 using Unix sockets for backends.
425 session_shared: fix integer overflow problem with hit count.
427 session_shared: avoid long usage of cached queries.
429 zoom: New database argument , torus_url to set URL of Torus
430 record to be fetched.
432 --- 1.3.38 2012/07/04
434 Fixes for 'metaproxy reload' for RPM/Debian packages.
436 zoom: Allow rpn2cql conversion to be augmented with a properties file.
437 Element rpn2cql can be specified per-target for the zoom filter.
439 log: New category "line" which is a single-line log message with
440 most important parts of a HTTP/Z39.50 request/response.
442 --- 1.3.37 2012/06/01
444 frontend_net: add facility to report live statistics about response
445 times and current thread usage. The report is an XML document
446 and is triggered for a specific URL path. This is set by <stat-req>
447 in the configuration of frontend_net. By default this report is
448 disabled (same as empty value for <stat-req>).
450 Fix reload problem in init.d script for RPM/Debian.
451 The '/etc/init.d/metaproxy reload' in some cases would stop but not
452 start metaproxy - effectively stopping the service.
454 Don't display start log message when config testing (-t).
456 zoom: avoid CCL message limit of 1K in ZOOM filter.
458 --- 1.3.36 2012/05/10
460 metaproxy init script reacts to reload which does graceful stop +
461 start and is used by logrorate script.
463 --- 1.3.35 2012/05/09
465 Fixes for Windows compilation.
467 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
468 existing sessions running but terminate the monitor process that is
469 used in keepalive mode.
471 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
472 before. Consistent with 'metaproxy stop' message.
474 zoom: document zoom's proxy_timeout
476 z3950_client: fixup addinfo for init response
478 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
479 "Access to specified database denied" is returned, but only if init
480 response from backend does not carry diagnostics already.
482 multi: relays user info for first rejected target. The other-information
483 field for init response for first rejected target is in common init
484 response. This ensures that some backend init diagnostics are returned to
487 --- 1.3.34 2012/04/25
489 frontend_log: extend logging (when message is given in config).
491 --- 1.3.33 2012/04/25
493 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
495 --- 1.3.32 2012/04/24
497 sru_z3950 filter passes through incoming Z39.50 requests again. Was
498 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
500 --- 1.3.31 2012/04/24
502 zoom: fixes for retry/proxy failover logic. More logging.
504 --- 1.3.30 2012/04/23
506 zoom: return addinfo="proxy failure" for proxy failures. This also
507 changes the scheme for dealing with proxies a bit. zoom now always
508 do proxy check, even if there's no failover. Fortunately, that's not
511 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
512 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
513 generic. We don't know why the init would fail; IP, user, block IP, etc.
514 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
516 zoom: guess if invalid SRU response was an auth failure
518 session_shared: disable session retry by default . Can be enabled by
519 restart="true" in resultset section.
521 --- 1.3.29 2012/04/18
523 zoom: may read cf-proxy's config settings.
524 This reduces manual configuration of the content proxy server host.
525 The ZOOM module will use the old style session.proxyhost if "server"
526 is given (deprecated) and use the new style proxyhost/session if
527 "config_file" is in use.
529 frontend_net: remove incoming requests that can not be handled
530 Requests in queue for filter frontend_net are removed if client
531 closes connection for the session and request is not yet handled.
533 sru_z3950: serialize requests. This is to ensure that pipelined
534 HTTP requests are handled properly.
536 --- 1.3.28 2012/04/04
538 New class, wrbuf, that wraps YAZ' WRBUF.
540 --- 1.3.27 2012/03/30
542 Metaproxy daemon is now running as user "metaproxy". This user is
543 managed by package maintainer scripts. The user information is stored
544 in /etc/metaproxy/metaproxy.user .
546 --- 1.3.26 2012/03/20
548 New filter, sort, that allows sorting of XML records via Z39.50
551 Filter record_transform: USEMarcon support. For example:
552 <retrieval syntax="usmarc">
553 <backend syntax="unimarc" name="F">
554 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
558 Filter multi: empty route pattern uses route as default.
560 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
561 may use the shorter notation
562 <target route="z3950.indexdata.com"/>
564 Filter query_rewrite: use config path to locate XSLT.
566 Filter frontend_net: log statistics.
567 If a custom message element in frontend_net configuration it makes
568 the frontend_net filter produce a log entry whenever an operation
569 is completed. The log is always written using yaz_log with the
570 custom message given, the package ID (session ID) , the time
571 the operation has been active (end-to-end) , the threads currently
572 active/total and the size of the request input/output queues.
574 query_rewrite: charset conversion of query terms.
575 This is an optional feature. Enabled by element <charset> in
576 configuration with attribute 'from' and 'to' that specifies
577 from/to encodings. The default 'from' encoding is UTF-8.
579 Filter record_transform: honor piggyback searches.
581 Filter zoom: re-connect when database is reused.
582 Re-connect is necessary if a connection is lost or a timeout occurs.
583 If not, we'll be seeing zero hits, when we shouldn't.
585 --- 1.3.25 2012/02/29
587 zoom: Change scheme for dealing with content proxy URLs. The module
588 now has its own common XSL transform that is enabled by record_xsl
589 attribute in the configuration. This XSL gets parameter cproxyhost
590 that holds the host for the content proxy session . The genearted-url
591 is created only if urlRecipe is enabled. In previous version default
592 value of urlRecipe was ${md-electronic-url}; it is now empty and
593 disabled by default. Also generated-url no longer includes the content
594 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
597 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
598 connections. Default value is 40 (seconds).
600 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
601 "Malformed query" for syntax errors and related ones; throw
602 Bib-1: 3 "Unsupported search" for everything else. Details from
603 the CCL parser is provided as additional-info.
605 multi: new setting hideerrors that makes multi only relay diagnostics
606 to a client if all backends fail.
608 --- 1.3.24 2012/02/23
610 zoom: empty ccl_map field-mappings disables CCL map.
612 zoom: fix Explain search that could return error if session was
615 --- 1.3.23 2012/02/10
617 zoom: returns Explain records for database IR-Explain---1. The
618 target profile records are converted to Explain records via XSLT.
620 session_shared: make error recovery configurable. Whether a search
621 is restarted on errors or not, is configurable by attribute "restart"
622 in element "resultset" in configuration.
624 session_shared: only relay init for first request. session_shared, for
625 each backend class, now only relays first init request (rather than all).
626 The module only needs to save init response info once. This avoids the
627 need to check for session max.
629 --- 1.3.22 2012/02/02
631 zoom: fix memory leaks.
633 session_shared: maximum number of sessons is configurable. Default
634 value is 100. Result-sets for backends without named result sets are
635 only re-used if databases is identical for a search. This is under the
636 assumption that performance may suffer for those backends when
637 changing the database for each search.
639 multi: combines diagnostics from all backends. All diagnostics from
640 backends are combined into multiple non-surrogate diagnostics; rather
641 than just one diagnostic from first backend.
643 --- 1.3.21 2011/12/27
645 zoom: relay realm to cproxy parameter file.
647 Configuration: Allow filter collection element inside route. This
648 makes it possible to include multiple filters at once.
650 zoom: nocproxy also disables urlRecipe.
652 --- 1.3.20 2011/12/21
654 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
655 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
656 90: "Unsupported direction value".
658 zoom: honor database argument nocproxy. This disables creating a content
659 connector session (for non-CF targets, usually) and also relays nocproxy
660 as database argument to a CF target.
662 --- 1.3.19 2011/12/16
664 zoom: Multiple proxy hosts may be given for proxy rich database
665 parameter. List is comma separated.
667 http_file: decodes URI paths properly. Does not return 404: not found
668 if no prefix are matches. Instead packages are passed on.
670 --- 1.3.18 2011/12/08
672 zoom: content-{user,password,proxy} are passed on to content proxy
673 system and takes precedence over user,password,proxy .
675 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
676 with a log element including log material from children filters. At
677 this point, only the zoom filter uses this log facility. It will
678 eventually be used by other filters as well. In particular it might be
679 useful for this feature to track all filters in used during a search.
681 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
682 and queries as they are manipulated are logged.
684 zoom: extend addinfo with native diagnostics. Diagnostics as received
685 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
686 diagnostics. This indicates both a backend diagnostic and the original
689 zoom: default urlRecipe value is ${md-electronic-url}
691 zoom: target profile setting sruVersion is recognized.
693 --- 1.3.17 2011/11/17
695 zoom: log target profile record fetched (AKA Torus).
697 --- 1.3.16 2011/11/17
699 Change target profile parameter CfSubDb to CfSubDB.
701 --- 1.3.15 2011/11/12
703 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
704 makes sense to the zoom module itself).
706 --- 1.3.14 2011/11/11
708 zoom: realm may be given as part of database.
710 --- 1.3.13 2011/10/26
712 Fix Origin class assigment method; was removd by mistake in 1.3.12.
714 --- 1.3.12 2011/10/26
716 zoom: database args x-name=value are passed through to backend database.
718 SRU filter: user may specify session ID that is passed to log entries
719 that follows. It is specified by using x-session-id in the SRU arguments.
721 zoom: fix null pointer reference which would occur for bad url parameter
722 inside "torus" or if url was not given.
724 --- 1.3.11 2011/09/09
725 Fix bug in filter session_shared where sessions would not expire
726 properly (session ttl). This in turn could make the target close the
727 connection before expected and session_shared would return diagnostic
728 2: system temporarily available.
730 --- 1.3.10 2011/09/09
732 zoom: new target profile setting: sortmap_field. If sortmap_field is given
733 the field is mapped to the value for the sortmap. Values not matching
734 sortmap_field are passed verbatim.
736 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
737 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
738 depending on whether RPN or CQL is actually sent to the target.
742 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
744 zoom: For content proxy authentication is stored in param name
745 "auth", instead of "authentication".
749 zoom: relay schema in SRU mode. Previously recordSchema was not affected
754 zoom: new target profile element literalTransform that holds XSLT
755 (encoded as string) for target. Only if present and non-zero length it is
756 considered present. This takes precedence over transform.
758 Don't rely on trang anymore for Git checkout builds. Configuration in etc
759 will only be properly validated if trang is available. From now on only
760 relax NC files are bundled with the source dist.
762 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
763 component was not detected when it should be.
767 z3950_client: mark non-surrogate diagnostics from backend.
769 zoom: a proxy may be specified for HTTP fetch of target profiles.
773 Honor piggyback. Makes some SRU targets behave that insist on
774 maximumRecords > 0, but also increases performance.
778 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
779 file was not update for libdir/metaproxy4 in version 1.3.2.
783 Change location of Metaproxy modules from libdir/metaproxy to
784 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
785 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
787 New facility to dump APDUs from zoom filter. Enabled by
788 <log apdu="true"/> in the zoom filter configuation.
790 zoom filter bug fix: SRU diagnostics received from backend was
791 not properly converted to Bib-1 diagnostics.
793 Package metaproxy depends on libmetaproxy4, same version.
797 zoom: fix a bug WRT passing authentication parameters to backends.
801 Fixes for windows Makefile.
803 --- 1.2.10 2011/07/25
805 Change major version of metaproxy library from 3 to 4. This in turn
806 makes new package names for Debian and RPM.
810 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
813 zoom: configurable element sets for record transforms.
815 zoom: the target profile based transform is specified by element_transform
816 in element torus of of the ZOOM filter configuration ; default value
817 is "pz2". Target profile based retrieval is specified by element_raw
818 in configuration. It will perform same steps, but omit the XSL transform.
819 Default value is "raw".
821 zoom: element set is omitted if not set in profile. But only if pz2
822 transform is in effect. Previously the default element set was to "F".
824 zoom: For non-CF targets database arguments are parsed. User may supply
825 db,user=myuser&password=mypass for non-CF targets. These values override
826 what's given the authentication from the target profile.
828 session_shared: fix reference to freed memory. Would occur if a search
829 response had non-surrogate diagnostics.
833 Route may be given for each port in frontend_net.
837 Documentation for zoom filter. Local target profiles may be specified.
839 Fixes for zoom filter.
843 First version with zoom filter.
847 Filter z3950_client may be configured to always send a close APDU
848 to backend target when connection/session is closed. This will only
849 happen if close APDU is not already sent. Enabled by configuration
850 for z3950_client (force_close).
852 Filter virt_db and multi: relay close APDU.
854 Filter virt_db and multi: relay init size parameters
855 preferredMessageSize and maximumRecordSize.
857 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
861 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
863 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
864 as determined by configure.
866 RPM: Release includes 'indexdata' name. Use indexdata in release name so
867 this package can be distinguished from other vendors.
871 Fix filter multi: relay idAuthentication parameters.
875 Add metaproxy-config for returning compiler flags, libraries.
879 Fix --with-boost=PREFIX .
883 session_shared: fix use of maintenance thread.
885 Introduce 'start' method for filters and routers. It gets called after
886 configure and after fork, but before processing. This changes API -
887 from libmetaproxy2 to libmetaproxy3.
891 session_shared: ensure backend session is closed if init rejected
894 z3950_client: fix NULL ptr reference that could occur if two clients
895 connected concurrently and if max-sockets was in effect.
899 Fix bug 3497 - Metaproxy unstable while stopping.
901 Fix bug 3495 - SEGV in SRU filter.
905 Filter multi throws diagnostic 'Present Out of Range' when
906 appropriate - rather than returning 0 records.
908 Filter virt_db: fix bad result reuse. Could happen if a result
909 was overriden and a backend did not supported named result sets.
913 Filter log: category access logs diagnostics even if searchStatus
914 or presentStatus is 'success'.
918 The SRU to Z39.50 filter does repeated Z39.50 present requests
919 to fetch all records. Needed when a Z39.50 server returns partial
920 results (due to message size limits).
924 Metaproxy now kills all child processes that are spawned by
925 modules (in case of fork, exec).
929 Debian package now installs /etc/metaproxy/metaproxy.xml which
930 includes all XML files /etc/metaproxy/filters-enabled .
931 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
935 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
936 development package to facilitate 3rd party Metaproxy modules.
938 --- 1.0.23 2010/01/04
940 Filter virt_db: Close backend filter session when Init rejected is received
941 from it (in which case it's not really closed yet). This will ensure we don't
942 run out of resources such as FDs in this case.
944 sru_z3950 filter: Accept any database (including those not listed).
946 --- 1.0.22 2009/12/03
948 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
949 later which means YAZ 3.0.47 or later.
951 --- 1.0.20 2009/11/19
953 For filter virt_db, the database is a glob pattern and the virtual
954 database sections are consulted in the order given.
956 --- 1.0.19 2009/07/08
958 For filter multi, the target (for routing) may be given as a glob-pattern.
960 More documentation for filters virt_db and multi.
962 Update schema to allow for no database in sru_z3950 filter.
964 --- 1.0.18 2009/06/30
966 Added limit filter to put sleep (penalty) for heavy use.
968 Filter frontend_net may be configured to limit the number of new connections
969 from same IP to some value (connect-max).
971 Fixed the load_balance filter.
973 --- 1.0.17 2009/06/16
975 Fix path for metaproxy executable for Debian init.d script.
977 --- 1.0.16 2009/06/10
979 SRU to Z39.50 filter honors x-username and x-password. If only
980 x-username is given that translates to open authentication (Z39.50v2). If
981 both x-username and x-password is present that translates to idPass
982 authentication (Z39.50v3).
984 New facility to change current working directory (-w).
986 Update to upstream skeleton of init.d script. Should fix bug #2619.
988 Filter session_shared now caches records (used to only cache connections
991 Filter session_shared now invalidates a Z39.50 session if a server
992 returns -1 hits. This facility was also part of yazproxy and gets around
993 a bug in Voyager-based Z39.50 servers.
995 --- 1.0.15 2008/11/18
997 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
999 --- 1.0.14 2008/06/09
1001 Fixed the value of SRU record schema in searchRetrieve response. It was set
1002 to a fixed value of "dc" before.
1004 Serialize identical SRU requests. This is useful if HTTP client software
1005 fires identical requests against metaproxy.
1007 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1008 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1009 avoid static configuration. This facility is handled by the sru_z3950 module
1010 and the z3950_client module.
1012 Allow maximum number of sockets to be used for a Z39.50 client by the
1013 use of SRU extra parameter x-max-sockets. This facility is handled by the
1014 sru_z3950 module and the z3950_client module.
1016 --- 1.0.13.1 2008/02/29
1018 Simplified check for Boost libraries.
1020 --- 1.0.13 2008/02/29
1022 First Debian package.
1024 The sru_z9350 filter now recognizes SRU parameter z-target as being
1025 a ZURL of the form host/database .
1027 Mergetype may be specified for filter 'multi'.
1029 --- 1.0.12 2007/09/19
1031 Fixed problem in Makefile WRT library specifictions. This could produce
1032 linker errors (when they should not happen).
1034 Fixed bug #1341: MetaProxy returning different results. Problem was that
1035 fix-up of record database did not normalize the database name.
1037 Documentation updates for Windows compilation.
1039 --- 1.0.11 2007/06/14
1041 Fixed problem with logfile being truncated.
1043 --- 1.0.10 2007/05/23
1045 Fixed bug #1136: Access rights not enforced.
1047 Extension for log module. The log category 'access' logs more details.
1048 New category 'user-access' added which is simlar to 'access' but adds
1049 the Z39.50 user as for all entries in a session.
1053 Added support for configurable default/force target/vhost for module Z39.50
1056 --- 1.0.8 2007/01/25
1058 Implemented filter, session_shared, which optimizes usage of Z39.50
1059 sessions and result sets.
1061 New filter, record_transform, which converts MARC/XML records.
1063 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1065 New filter, load_balance, in development.
1067 New filter, zeerex_xplain.
1069 XML framework for config files started.
1071 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1072 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1073 XML config files are checked against RNG and XML Schema's.
1075 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1076 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1077 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1078 explain record to YAZ CQL-to-PQF text config file.
1080 --- 1.0.7 2006/11/07
1082 Added 'timeout' setting for filter frontend_net which specifies the number
1083 of seconds a session is idle before it is closed. Default timeout is
1086 --- 1.0.6 2006/07/07
1088 Database name in records returned set for virt_db/multi filters.
1090 Filter session_shared now functional.
1092 Log filter can be configured to write to a given file using 'filename'
1093 element. Also information category can be specified with 'category'. If
1094 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1097 --- 1.0.5 2006/05/16
1099 Fixed compilation on Windows.
1101 --- 1.0.4 2006/05/16
1103 Added documentation for the hidenavailable option for the multi filter.
1105 --- 1.0.3 2006/05/16
1107 Fixed bug #573: Hide errors for individual servers. If the element
1108 'hideunavailable' is given in the configuration, individual servers
1109 being unavailable are hidden (unless all are unavailable).
1111 Fixed bug #574: Database names are recognised case-sensitively.
1113 Fixed bug #567: Fix up database name in Name-Plus-Record.
1115 Fixed bug #568: Update win/makefile for VS 2005.
1117 Fixed bug #569: Some options throws unknown exception.
1119 --- 1.0.2 2006/04/28
1121 More information about virtual hosts. The 'etc' directory is part of the
1124 --- 1.0.1 2006/04/27
1126 Build instructions for Windows. NMake makefile part of distribution tar.
1128 --- 1.0.0 2006/04/24
1132 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1133 log, multi, query_rewrite, template, virt_db, z3950_client.
1135 Filters in development: session_shared.
1137 Pseudo-filters: template, dl
