10 The cql_transform_rpn2cql_stream_r returns Bib-1 diagnostics; not
13 deb: deprecated substitution ${Source-Version} MP-621
15 Fix systemd: reload stops metaproxy MP-620
16 Detect systemd and just do nothing when reload/force-reload is
17 used. Log, however, that it really is not reloading.
19 Add http-req-max to frontend_net MP-617
23 Fix multi: hideunavailable don't hide target that timeout MP-615
27 Fix race condition in MP log output MP-522
29 Fix 'Group' is duplicated twice in RPM spec
31 Fix crash in log filter when record syntax is omitted MP-613
33 Change target z3950.loc.gov:7090/voyager -> lx2.loc.gov:210/LCDB_MARC8
36 Fix Control-C does not stop Metaproxy spawned by shell MP-610
37 Check for fork mode instead (-D) - rather than debug (-X)
41 sru_z3950: allow CCL in SRU search MP-606
42 Makes the sru_z3950 filter convert to CCL queries if query type
43 "ccl" is used, eg ?query=water&queryType=ccl&... for SRU 2.0.
47 Fix dead lock in session_shared (init) MP-605
51 Fix session_shared caches set with diagnostic MP-604
53 Fix assertion failed in session_shared filter MP-603
55 Make /usr/share/metaproxy be part of metaproxy RPM MP-601
57 Log YAZ version upon start MP-599
61 sru_z3950: undo Serialize identical SRU GET requests MP-598
62 Now much more elegantly handled by session_shared.
64 session_shared: anticipated init and search MP-597
66 z3950_client: separate init timeout MP-596
67 Both init-timeout and connect-timeout are configurable by this change.
68 Default is 10 seconds.
72 zoom: support cf_-params MP-595
74 http_client: returns 404 if no destination URI is given
78 zoom: allow / in user and password db args MP-592
82 Log rotate no longer reloads configuration - instead Metaproxy just
83 re-opens log files when SIGHUP is received. MP-485
85 Debian : init.d metaproxy reload should check configuration MP-591
87 Fix Metaproxy stops logging after check config failed MP-590
91 Fix double free in log filter (with incorrect config) MP-589
93 zoom: Add allow_ip feature - fixes MP-588
94 Allow a list of IPs to be given separated by blanks
95 <allow auth_url="http://mkc-admin.indexdata.com/..."
96 allow_ip="127.0.0.1 ::1" .. >

128 Add support for binding outgoing IP for http_client and z3950_client
129 This is enabled by bind_host setting. MP-575
133 z3950_client: allows negotiation charset to be set MP-574
135 cgi: more functional but no support for POSTed content yet (part of MP-564)

139 http_file: add include of sys/stat.h fixes MP-576
141 Fix documentation about SRU client support MP-572
143 Initialize Libxml2 - for threaded operation MP-571
145 --- 1.5.10 2014/08/26
147 On SIGTERM shut down connection+listening sockets MP-568
148 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
152 zoom: make retry on failure configurable MP-565
153 The default and existing behavior is that backend failures (any
154 diagnostic) makes the module re-search once. The behavior may
155 be changed by db parameter 'retry'. If given value '0' disables
156 retry and '1' enables it. If not given, the Torus record may
157 specify with element retryOnFailure (value '0'/'1').
161 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
162 instead of just a child process. Extremely rare in real life, hit me with
163 CF stress testing. MP-559.
167 http_file: passthru option MP-557
168 New facility for http_file to passthru - even if an area is matched. The
169 default behavior (passthru=false) is to return 404: Not found. With
170 passthru=false, next filter is consulted.
174 Fix ref to freed memory in log filter 1line - MP-556
176 echoedSearchRetrieveRequest support MP-555
180 zoom: allow hostname to be given for ipauth MP-552
181 The Torus setting for that is called auth_hostname.
185 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
189 session_shared: close in ~BackendInstance MP-549
190 This fixes a serious issue where some MP would leak sockets.
192 session_shared: mutex lock in BackendClass::release_backend MP-550
193 Fixes a SEGV that could occur (in rare cases).
197 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
199 zoom: fix invalid present response in some cases MP-546
201 zoom: Relay Torus HTTP error message
205 Check for proper limits before using RecordCache functions MP-544
209 Build packages for Ubuntu Trusty Tahr 14.04 LTS
211 sort: crash / invalid_read in filter sort MP-541
213 sru_z3950: facet should be stored in additionalSearchInfo MP-533
215 doc: fix missing man pages MP-542
217 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
219 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
223 sru_z3950: fix facet response (memory corruption) MP-532
225 log: fix crash idPass user is omitted MP-530
229 query_rewrite: pass-thru non Type-1 queries MP-527
231 metaproxy stop (SIGTERM) kills all child processes spanwed by
232 filter (if any) before invoking filter destructors. MP-525
236 http_file: only supports HTTP GET MP-523
238 session_shared: shut down expire thread in destructor
239 This ensures that expire thread is not running after destruction
240 and does bad memory references, etc.
242 frontend_net: fix segfault on startup MP-524
243 Would happen if MP was listening on multiple ports and one
244 of the ports was already in use (and MP would exit).
246 frontend_net: fix memory leak MP-521
247 This leak would occur if all sessions were in use and the input
248 queue was cleared when a client would close connection (socket).
250 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
254 http_rewrite: use local skiplist; fixes memory corruption. MP-520
256 http_client: x-forwarded-for controls X-Forwarded-For presence
257 If x-forwarded-for setting (boolean) is enabled, http_client will
258 generate an X-Forwarded-For header entry which includes existing
259 X-Forwarded-For (if any) and current peer address (immediate client
260 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
261 will not be generated.
263 z3950_client: client_ip controls client-IP presence
264 If client_ip setting (boolean) is enabled, z3950_client will
265 generate a client_ip OID as part of init request which includes
266 previous client_ip (if any) and current peer address (immediate
267 client of Metaproxy). By default client_ip is disabled and client_ip
268 will not be generated.
270 HTTP X-Forwarded-For/Z39.50 Client-IP support
271 virt_db, multi: relays Z39.50 client-IP.
272 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
273 zoom: uses Client-IP or origin address (prefer Client-IP).
274 frontend_net: Strips tcp: from peer address (so that it is no longer
275 printed and stripped in zoom filter).
276 z3950_client: builds client-IP list - combining immediate peer address
277 as returned by COMSTACK and existing client-IP list (if avaiable).
278 The Origin only printes first X-Forwarded address.
282 Log when SIG{TERM,USR1} is received ASAP MP-513
283 Do it in frontend_net event loop rather than in place for metaproxy
284 main, which only exits when all sessions are terminated for SIGUSR1
287 metaproxy-config: quote some RHS values (that might include blanks)
289 Fix leak in sru_z3950 filter - when explain is returned MP-511
291 Allow stylesheet to be given for sru_z3950 filter MP-510
292 This is based on a patch by Sven Porst and the functionality
293 of the YAZ Generic Frontend Server.
295 Allow base attribute in configuration file tags - the attributes are
296 inserted by XInclude usage as mentioned on
297 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
298 and noted in a gist: https://gist.github.com/3551094
300 Package metaproxy provides virtual package metaproxy6 MP-508
301 This allows module packages to depend on a metaproxy server
304 Filter destructors called upon daemon termination MP-505
305 When metaproxy daemon receives SIGTERM the stop method of each filter
306 is called. The stop method existed before, but did not take any
307 arguements (void).. The frontend_net filter can now distinguish
308 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
309 (stop immediately). Note that this changes the API+ABI of Metaproxy
312 zoom: sync up with Pazpar2 WRT authentication handling MP-492
314 Router: use shared_ptr rather than naked one - to avoid leak if an
315 exception is thrown in configure.
319 zoom: Add nocproxy=1 for contentConnector sessions MP-501
321 Doc: mention proper versions; fix link to Boost win binaries.
323 Windows: update for Boost 1.55
325 Windows: avoid warning when using boost::split. Done by defining
326 _SCL_SECURE_NO_WARNINGS for Visual Studio.
328 Fix LSB conformance for /etc/init.d/metaproxy MP-500
329 Debian: add support for /etc/init.d/metaproxy status
331 sort: Add const to Record less than operator in order to compile on
336 session_shared: fix element-set handling in record caching. MP-499
338 document http_rewrite. MP-468
340 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
341 respects the header (which will normally come from the cproxy filter)
345 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
346 RPM was unsable in version 1.4.0.
348 Remove log message about "backend classes". Appeared in version 1.4.0.
352 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
353 with older version from source, but packages now use YAZ 5 that supports
356 sru_z3950: Fix SEGV for decoding invalid SRU requests
357 Incorrect reference to union (was explain response rather than
360 session_shared: match additionalSearchInfo (includes facets). In
361 layman's terms means that means that facets are properly handled
362 by this filter. Eg a change in requested facets will issue new
363 search and facets from exisiting result set are cached.
365 --- 1.3.62 2013/09/11
367 http_rewrite: better handling of <script> content in HTML parser. MP-486
369 http_rewrite: fix threading issue with regex. MP-482
371 bounce: don't use strdup for fixed length content. Error occurred in echo
374 session_shared: expire backend class when no instances left. This
375 means memory clean up, but not really a leak fix.
377 virt_db: fix leak for naked ptr.
379 cql_rpn: use config relative path for cql2rpn file. MP-481
381 Updates for upcoming YAZ 5.
383 --- 1.3.61 2013/08/29
385 New configuration directories ports.d/routes.d for metaproxy
386 configuration. This allows 3rd party packages to install config
387 for ports and new routes. MP-477
389 --- 1.3.60 2013/08/21
391 Fix metaproxy-config --libs to return non-mt over mt libs.
392 The -mt versions do not exist as shared objects and cause
393 linker errors for applications linking with Metaproxy.
394 Problem present in versions 1.3.56 - 1.3.59. MP-475
396 HTML: clean up char checks. Add ptr to HTML parse spec
398 HTML parser stops eating tag when <-char is met MP-473
400 rewrite: do not even compare content types, if we don't have any
401 the regex_match caused a segfault if we had no content-type in the
404 rewrite: within header=... matches only the header value
405 Used to match the whole header line, but we need to use
406 ^$ anchoring for host-relative regexps, and they need to
407 anchor at the ends of the value. MP-470.
409 rewrite: Ruleset functional MP-469
411 --- 1.3.59 2013/07/12
413 session_shared: negotiate init sz parameters.
414 By default, session_shared will honor the paramters given by client.
415 An alternative, but not implemented, algorithm would be to only
416 re-use sessions with same sz parameters. This however, could reduce
417 re-use of sessions a lot. Hence this, simple algorithm instead. The
418 negotiation to a maximum sz values can be enabled by using
419 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
420 in configuration. This will make session_shared send those values
421 to backends and use returned init values in negotaition to
422 client before session_shared.
424 session_shared: resolve result-set references.
425 The reference is substitued with the query for old set if database
426 match and query type is Type-1. If not the reference will issue a
429 sort filter: relays RecordComposition including elementSet in use for
432 http_client: better diagnostics
434 http_client: disables HTTP redirect handling by default.
435 It can be configured with max-redirects in configuration.
437 --- 1.3.58 2013/06/12
439 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
441 --- 1.3.57 2013/06/12
443 Make RouterChain and RouterXML part of public API (libmetaproxy).
445 http_client: honor X-Metaproxy-Proxy as an alternative to
446 the "proxy" configuration. Allows proxy to be set per HTTP request.
448 sru_z3950: For SRU requests recognize x-client prefixes as a way
449 to ingest "database parameters".. The suffix of x-client- serves
450 as database argument name. Multiple may be given. For example:
451 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
452 is turned into Z39.50 database
455 --- 1.3.56 2013/05/27
457 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
459 New filter sd_remove, which replaces surrogate diagnostics with
460 SUTRS records. This filter tries to deal with clients that breaks
461 when receiving surrogate diagnostics.
463 new filter http_client. Same role as z3950_client, but just for
464 HTTP. Allows Metaproxy to operate as a HTTP proxy.
466 New filter http_rewrite1, which serves as purpose on how to rewrite
467 HTTP content with Metaproxy.
469 Use libboost-system if available, because newer versions of libboost-threads
470 requires libboost-system.
472 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
475 --- 1.3.55 2013/04/10
477 zoom: Torus setting: authenticationMode which may hold values "basic"
480 --- 1.3.54 2013/03/27
482 configure: check for Libxslt support in YAZ and rely on definitions
483 from yaz-config, rather than doing own xslt/xml2 checks.
485 Allow timestamp format for log lines to be given with option -m
486 for metaproxy. Similar to yaz-ztest/GFS option -m.
488 Document log category 'line' for log filter.
490 Solr configuration example in etc/config-solr.xml
492 multi: do not mess with request package. For scan and search,
493 database-names were modified and the request package was left with
494 dangling pointers that caused a log filter to fail (request package
495 inspected after multi was invoked).
497 Documentation: fix id of metaproxy-config ref .
499 Documentation: update for USEMARCON support.
501 --- 1.3.53 2013/01/31
503 record_transform: allow OPACXML to OPAC conversion
505 zoom: document content-proxy
507 zoom: document db parm content-{user,password}, torus_url. Also
508 <torus auth_url="..> which makes zoom operate in authenticated mode
511 --- 1.3.52 2012/11/30
513 zoom: fix http://-check. SRU search broken in 1.3.51.
515 --- 1.3.51 2012/11/15
517 zoom: only append http:// for SRU if not already given . Makes it
518 possible to use https-URLs.
520 Use yazpp 1.4 or later due to new ABI.
522 frontend_net: allow max package size to be specified. Controlled by
523 attribute 'max_recv_bytes' of element 'port'.
525 --- 1.3.50 2012/10/29
527 For most generated diagnostics by filters, typically temporary
528 system error, augment addinfo message with filter name.
530 Add support for CentOS 6 packages.
532 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
534 Add man page for metaproxy-config.
536 --- 1.3.49 2012/10/18
538 zoom: new config element passthru. This defines an element set that is
539 passed verbatim to the backend in pz2 mode.
541 auth_simple: allow both idPass and open auth. Also fix SEGV that could
544 --- 1.3.48 2012/10/08
546 z3950_client: fix string handling for init diagnostics in the case where
549 query_rewrite: no charset conversion for error queries. Avoid performing
550 charset conversion for query conversion errors. The resulting Type-1
551 query is invalid in this case.
553 --- 1.3.47 2012/10/04
555 For graceful stop (SIGUSR1), metaproxy will kill children processes.
557 Log when metaproxy is invoked in test mode (-t).
559 Log PID for each log message.
561 multi: combine both NSDs and multiple NSDs into one (diagnostics).
563 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
564 a (backend=target) is appended for each diagnostic so that can be
565 determined the origin of error.
567 multi: hideerrors also in use for present response.
569 Solr example in zoom man page.
571 Fix typo in query_rewrite config example.
573 Log at least first non surrogate diagnostic. Instead of
574 "Z_Records_multipleNSD"
576 multi: Fix check for opt Records in present response. A SEGV could occur
577 if a target did not return records and no diagnostics.
579 --- 1.3.46 2012/09/24
581 Yet another fix for graceful stop.
583 --- 1.3.45 2012/09/12
585 sru_z3950: relay surrogate diagnostics.
587 --- 1.3.44 2012/09/10
589 zoom: Honor extraArgs, strip # in zurl.
591 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
593 zoom: url_recipe allow %{var[reg]} substitutions.
594 It's like ${var[reg]} but does URI component encoding as well.
596 --- 1.3.43 2012/08/22
598 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
599 non-keepalive HTTP sessions.
601 http_file: allow zero size files (bug fix)
603 Fix zoom schema: auth_url is optional
605 --- 1.3.42 2012/08/20
607 zoom: fix un-init memory (could result in SEGV at session close)
609 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
610 and may be used in filters as usual.
612 zoom: authentication via Torus lookup
613 Enabled by new configuration setting: auth_url . If this is defined,
614 the zoom module will contact Torus for auth/IP lookup and that will
615 define realm to be used in session.
617 --- 1.3.41 2012/08/10
619 virt_db: Fix database name - first character we removed by mistake.
620 Bug introduced in 1.3.40.
622 --- 1.3.40 2012/08/06
624 virt_db: Don't use "unix path" as database for Unix sockets.
626 --- 1.3.39 2012/08/02
628 z3950_client: Don't tamper with / in zurl - fixes problems
629 using Unix sockets for backends.
631 session_shared: fix integer overflow problem with hit count.
633 session_shared: avoid long usage of cached queries.
635 zoom: New database argument , torus_url to set URL of Torus
636 record to be fetched.
638 --- 1.3.38 2012/07/04
640 Fixes for 'metaproxy reload' for RPM/Debian packages.
642 zoom: Allow rpn2cql conversion to be augmented with a properties file.
643 Element rpn2cql can be specified per-target for the zoom filter.
645 log: New category "line" which is a single-line log message with
646 most important parts of a HTTP/Z39.50 request/response.
648 --- 1.3.37 2012/06/01
650 frontend_net: add facility to report live statistics about response
651 times and current thread usage. The report is an XML document
652 and is triggered for a specific URL path. This is set by <stat-req>
653 in the configuration of frontend_net. By default this report is
654 disabled (same as empty value for <stat-req>).
656 Fix reload problem in init.d script for RPM/Debian.
657 The '/etc/init.d/metaproxy reload' in some cases would stop but not
658 start metaproxy - effectively stopping the service.
660 Don't display start log message when config testing (-t).
662 zoom: avoid CCL message limit of 1K in ZOOM filter.
664 --- 1.3.36 2012/05/10
666 metaproxy init script reacts to reload which does graceful stop +
667 start and is used by logrorate script.
669 --- 1.3.35 2012/05/09
671 Fixes for Windows compilation.
673 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
674 existing sessions running but terminate the monitor process that is
675 used in keepalive mode.
677 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
678 before. Consistent with 'metaproxy stop' message.
680 zoom: document zoom's proxy_timeout
682 z3950_client: fixup addinfo for init response
684 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
685 "Access to specified database denied" is returned, but only if init
686 response from backend does not carry diagnostics already.
688 multi: relays user info for first rejected target. The other-information
689 field for init response for first rejected target is in common init
690 response. This ensures that some backend init diagnostics are returned to
693 --- 1.3.34 2012/04/25
695 frontend_log: extend logging (when message is given in config).
697 --- 1.3.33 2012/04/25
699 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
701 --- 1.3.32 2012/04/24
703 sru_z3950 filter passes through incoming Z39.50 requests again. Was
704 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
706 --- 1.3.31 2012/04/24
708 zoom: fixes for retry/proxy failover logic. More logging.
710 --- 1.3.30 2012/04/23
712 zoom: return addinfo="proxy failure" for proxy failures. This also
713 changes the scheme for dealing with proxies a bit. zoom now always
714 do proxy check, even if there's no failover. Fortunately, that's not
717 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
718 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
719 generic. We don't know why the init would fail; IP, user, block IP, etc.
720 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
722 zoom: guess if invalid SRU response was an auth failure
724 session_shared: disable session retry by default . Can be enabled by
725 restart="true" in resultset section.
727 --- 1.3.29 2012/04/18
729 zoom: may read cf-proxy's config settings.
730 This reduces manual configuration of the content proxy server host.
731 The ZOOM module will use the old style session.proxyhost if "server"
732 is given (deprecated) and use the new style proxyhost/session if
733 "config_file" is in use.
735 frontend_net: remove incoming requests that can not be handled
736 Requests in queue for filter frontend_net are removed if client
737 closes connection for the session and request is not yet handled.
739 sru_z3950: serialize requests. This is to ensure that pipelined
740 HTTP requests are handled properly.
742 --- 1.3.28 2012/04/04
744 New class, wrbuf, that wraps YAZ' WRBUF.
746 --- 1.3.27 2012/03/30
748 Metaproxy daemon is now running as user "metaproxy". This user is
749 managed by package maintainer scripts. The user information is stored
750 in /etc/metaproxy/metaproxy.user .
752 --- 1.3.26 2012/03/20
754 New filter, sort, that allows sorting of XML records via Z39.50
757 Filter record_transform: USEMarcon support. For example:
758 <retrieval syntax="usmarc">
759 <backend syntax="unimarc" name="F">
760 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
764 Filter multi: empty route pattern uses route as default.
766 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
767 may use the shorter notation
768 <target route="z3950.indexdata.com"/>
770 Filter query_rewrite: use config path to locate XSLT.
772 Filter frontend_net: log statistics.
773 If a custom message element in frontend_net configuration it makes
774 the frontend_net filter produce a log entry whenever an operation
775 is completed. The log is always written using yaz_log with the
776 custom message given, the package ID (session ID) , the time
777 the operation has been active (end-to-end) , the threads currently
778 active/total and the size of the request input/output queues.
780 query_rewrite: charset conversion of query terms.
781 This is an optional feature. Enabled by element <charset> in
782 configuration with attribute 'from' and 'to' that specifies
783 from/to encodings. The default 'from' encoding is UTF-8.
785 Filter record_transform: honor piggyback searches.
787 Filter zoom: re-connect when database is reused.
788 Re-connect is necessary if a connection is lost or a timeout occurs.
789 If not, we'll be seeing zero hits, when we shouldn't.
791 --- 1.3.25 2012/02/29
793 zoom: Change scheme for dealing with content proxy URLs. The module
794 now has its own common XSL transform that is enabled by record_xsl
795 attribute in the configuration. This XSL gets parameter cproxyhost
796 that holds the host for the content proxy session . The genearted-url
797 is created only if urlRecipe is enabled. In previous version default
798 value of urlRecipe was ${md-electronic-url}; it is now empty and
799 disabled by default. Also generated-url no longer includes the content
800 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
803 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
804 connections. Default value is 40 (seconds).
806 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
807 "Malformed query" for syntax errors and related ones; throw
808 Bib-1: 3 "Unsupported search" for everything else. Details from
809 the CCL parser is provided as additional-info.
811 multi: new setting hideerrors that makes multi only relay diagnostics
812 to a client if all backends fail.
814 --- 1.3.24 2012/02/23
816 zoom: empty ccl_map field-mappings disables CCL map.
818 zoom: fix Explain search that could return error if session was
821 --- 1.3.23 2012/02/10
823 zoom: returns Explain records for database IR-Explain---1. The
824 target profile records are converted to Explain records via XSLT.
826 session_shared: make error recovery configurable. Whether a search
827 is restarted on errors or not, is configurable by attribute "restart"
828 in element "resultset" in configuration.
830 session_shared: only relay init for first request. session_shared, for
831 each backend class, now only relays first init request (rather than all).
832 The module only needs to save init response info once. This avoids the
833 need to check for session max.
835 --- 1.3.22 2012/02/02
837 zoom: fix memory leaks.
839 session_shared: maximum number of sessons is configurable. Default
840 value is 100. Result-sets for backends without named result sets are
841 only re-used if databases is identical for a search. This is under the
842 assumption that performance may suffer for those backends when
843 changing the database for each search.
845 multi: combines diagnostics from all backends. All diagnostics from
846 backends are combined into multiple non-surrogate diagnostics; rather
847 than just one diagnostic from first backend.
849 --- 1.3.21 2011/12/27
851 zoom: relay realm to cproxy parameter file.
853 Configuration: Allow filter collection element inside route. This
854 makes it possible to include multiple filters at once.
856 zoom: nocproxy also disables urlRecipe.
858 --- 1.3.20 2011/12/21
860 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
861 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
862 90: "Unsupported direction value".
864 zoom: honor database argument nocproxy. This disables creating a content
865 connector session (for non-CF targets, usually) and also relays nocproxy
866 as database argument to a CF target.
868 --- 1.3.19 2011/12/16
870 zoom: Multiple proxy hosts may be given for proxy rich database
871 parameter. List is comma separated.
873 http_file: decodes URI paths properly. Does not return 404: not found
874 if no prefix are matches. Instead packages are passed on.
876 --- 1.3.18 2011/12/08
878 zoom: content-{user,password,proxy} are passed on to content proxy
879 system and takes precedence over user,password,proxy .
881 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
882 with a log element including log material from children filters. At
883 this point, only the zoom filter uses this log facility. It will
884 eventually be used by other filters as well. In particular it might be
885 useful for this feature to track all filters in used during a search.
887 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
888 and queries as they are manipulated are logged.
890 zoom: extend addinfo with native diagnostics. Diagnostics as received
891 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
892 diagnostics. This indicates both a backend diagnostic and the original
895 zoom: default urlRecipe value is ${md-electronic-url}
897 zoom: target profile setting sruVersion is recognized.
899 --- 1.3.17 2011/11/17
901 zoom: log target profile record fetched (AKA Torus).
903 --- 1.3.16 2011/11/17
905 Change target profile parameter CfSubDb to CfSubDB.
907 --- 1.3.15 2011/11/12
909 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
910 makes sense to the zoom module itself).
912 --- 1.3.14 2011/11/11
914 zoom: realm may be given as part of database.
916 --- 1.3.13 2011/10/26
918 Fix Origin class assigment method; was removd by mistake in 1.3.12.
920 --- 1.3.12 2011/10/26
922 zoom: database args x-name=value are passed through to backend database.
924 SRU filter: user may specify session ID that is passed to log entries
925 that follows. It is specified by using x-session-id in the SRU arguments.
927 zoom: fix null pointer reference which would occur for bad url parameter
928 inside "torus" or if url was not given.
930 --- 1.3.11 2011/09/09
931 Fix bug in filter session_shared where sessions would not expire
932 properly (session ttl). This in turn could make the target close the
933 connection before expected and session_shared would return diagnostic
934 2: system temporarily available.
936 --- 1.3.10 2011/09/09
938 zoom: new target profile setting: sortmap_field. If sortmap_field is given
939 the field is mapped to the value for the sortmap. Values not matching
940 sortmap_field are passed verbatim.
942 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
943 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
944 depending on whether RPN or CQL is actually sent to the target.
948 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
950 zoom: For content proxy authentication is stored in param name
951 "auth", instead of "authentication".
955 zoom: relay schema in SRU mode. Previously recordSchema was not affected
960 zoom: new target profile element literalTransform that holds XSLT
961 (encoded as string) for target. Only if present and non-zero length it is
962 considered present. This takes precedence over transform.
964 Don't rely on trang anymore for Git checkout builds. Configuration in etc
965 will only be properly validated if trang is available. From now on only
966 relax NC files are bundled with the source dist.
968 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
969 component was not detected when it should be.
973 z3950_client: mark non-surrogate diagnostics from backend.
975 zoom: a proxy may be specified for HTTP fetch of target profiles.
979 Honor piggyback. Makes some SRU targets behave that insist on
980 maximumRecords > 0, but also increases performance.
984 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
985 file was not update for libdir/metaproxy4 in version 1.3.2.
989 Change location of Metaproxy modules from libdir/metaproxy to
990 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
991 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
993 New facility to dump APDUs from zoom filter. Enabled by
994 <log apdu="true"/> in the zoom filter configuation.
996 zoom filter bug fix: SRU diagnostics received from backend was
997 not properly converted to Bib-1 diagnostics.
999 Package metaproxy depends on libmetaproxy4, same version.
1001 --- 1.3.1 2011/07/28
1003 zoom: fix a bug WRT passing authentication parameters to backends.
1005 --- 1.3.0 2011/07/27
1007 Fixes for windows Makefile.
1009 --- 1.2.10 2011/07/25
1011 Change major version of metaproxy library from 3 to 4. This in turn
1012 makes new package names for Debian and RPM.
1014 --- 1.2.9 2011/06/27
1016 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
1019 zoom: configurable element sets for record transforms.
1021 zoom: the target profile based transform is specified by element_transform
1022 in element torus of of the ZOOM filter configuration ; default value
1023 is "pz2". Target profile based retrieval is specified by element_raw
1024 in configuration. It will perform same steps, but omit the XSL transform.
1025 Default value is "raw".
1027 zoom: element set is omitted if not set in profile. But only if pz2
1028 transform is in effect. Previously the default element set was to "F".
1030 zoom: For non-CF targets database arguments are parsed. User may supply
1031 db,user=myuser&password=mypass for non-CF targets. These values override
1032 what's given the authentication from the target profile.
1034 session_shared: fix reference to freed memory. Would occur if a search
1035 response had non-surrogate diagnostics.
1037 --- 1.2.8 2011/06/22
1039 Route may be given for each port in frontend_net.
1041 --- 1.2.7 2011/06/22
1043 Documentation for zoom filter. Local target profiles may be specified.
1045 Fixes for zoom filter.
1047 --- 1.2.6 2011/06/15
1049 First version with zoom filter.
1051 --- 1.2.5 2011/05/06
1053 Filter z3950_client may be configured to always send a close APDU
1054 to backend target when connection/session is closed. This will only
1055 happen if close APDU is not already sent. Enabled by configuration
1056 for z3950_client (force_close).
1058 Filter virt_db and multi: relay close APDU.
1060 Filter virt_db and multi: relay init size parameters
1061 preferredMessageSize and maximumRecordSize.
1063 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
1065 --- 1.2.4 2011/01/27
1067 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
1069 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
1070 as determined by configure.
1072 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1073 this package can be distinguished from other vendors.
1075 --- 1.2.3 2010/10/04
1077 Fix filter multi: relay idAuthentication parameters.
1079 --- 1.2.2 2010/09/15
1081 Add metaproxy-config for returning compiler flags, libraries.
1083 --- 1.2.1 2010/08/18
1085 Fix --with-boost=PREFIX .
1087 --- 1.2.0 2010/07/09
1089 session_shared: fix use of maintenance thread.
1091 Introduce 'start' method for filters and routers. It gets called after
1092 configure and after fork, but before processing. This changes API -
1093 from libmetaproxy2 to libmetaproxy3.
1095 --- 1.1.7 2010/06/30
1097 session_shared: ensure backend session is closed if init rejected
1100 z3950_client: fix NULL ptr reference that could occur if two clients
1101 connected concurrently and if max-sockets was in effect.
1103 --- 1.1.6 2010/06/21
1105 Fix bug 3497 - Metaproxy unstable while stopping.
1107 Fix bug 3495 - SEGV in SRU filter.
1109 --- 1.1.5 2010/06/15
1111 Filter multi throws diagnostic 'Present Out of Range' when
1112 appropriate - rather than returning 0 records.
1114 Filter virt_db: fix bad result reuse. Could happen if a result
1115 was overriden and a backend did not supported named result sets.
1117 --- 1.1.4 2010/05/11
1119 Filter log: category access logs diagnostics even if searchStatus
1120 or presentStatus is 'success'.
1122 --- 1.1.3 2010/04/21
1124 The SRU to Z39.50 filter does repeated Z39.50 present requests
1125 to fetch all records. Needed when a Z39.50 server returns partial
1126 results (due to message size limits).
1128 --- 1.1.2 2010/03/18
1130 Metaproxy now kills all child processes that are spawned by
1131 modules (in case of fork, exec).
1133 --- 1.1.1 2010/01/28
1135 Debian package now installs /etc/metaproxy/metaproxy.xml which
1136 includes all XML files /etc/metaproxy/filters-enabled .
1137 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1139 --- 1.1.0 2010/01/20
1141 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1142 development package to facilitate 3rd party Metaproxy modules.
1144 --- 1.0.23 2010/01/04
1146 Filter virt_db: Close backend filter session when Init rejected is received
1147 from it (in which case it's not really closed yet). This will ensure we don't
1148 run out of resources such as FDs in this case.
1150 sru_z3950 filter: Accept any database (including those not listed).
1152 --- 1.0.22 2009/12/03
1154 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1155 later which means YAZ 3.0.47 or later.
1157 --- 1.0.20 2009/11/19
1159 For filter virt_db, the database is a glob pattern and the virtual
1160 database sections are consulted in the order given.
1162 --- 1.0.19 2009/07/08
1164 For filter multi, the target (for routing) may be given as a glob-pattern.
1166 More documentation for filters virt_db and multi.
1168 Update schema to allow for no database in sru_z3950 filter.
1170 --- 1.0.18 2009/06/30
1172 Added limit filter to put sleep (penalty) for heavy use.
1174 Filter frontend_net may be configured to limit the number of new connections
1175 from same IP to some value (connect-max).
1177 Fixed the load_balance filter.
1179 --- 1.0.17 2009/06/16
1181 Fix path for metaproxy executable for Debian init.d script.
1183 --- 1.0.16 2009/06/10
1185 SRU to Z39.50 filter honors x-username and x-password. If only
1186 x-username is given that translates to open authentication (Z39.50v2). If
1187 both x-username and x-password is present that translates to idPass
1188 authentication (Z39.50v3).
1190 New facility to change current working directory (-w).
1192 Update to upstream skeleton of init.d script. Should fix bug #2619.
1194 Filter session_shared now caches records (used to only cache connections
1197 Filter session_shared now invalidates a Z39.50 session if a server
1198 returns -1 hits. This facility was also part of yazproxy and gets around
1199 a bug in Voyager-based Z39.50 servers.
1201 --- 1.0.15 2008/11/18
1203 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1205 --- 1.0.14 2008/06/09
1207 Fixed the value of SRU record schema in searchRetrieve response. It was set
1208 to a fixed value of "dc" before.
1210 Serialize identical SRU requests. This is useful if HTTP client software
1211 fires identical requests against metaproxy.
1213 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1214 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1215 avoid static configuration. This facility is handled by the sru_z3950 module
1216 and the z3950_client module.
1218 Allow maximum number of sockets to be used for a Z39.50 client by the
1219 use of SRU extra parameter x-max-sockets. This facility is handled by the
1220 sru_z3950 module and the z3950_client module.
1222 --- 1.0.13.1 2008/02/29
1224 Simplified check for Boost libraries.
1226 --- 1.0.13 2008/02/29
1228 First Debian package.
1230 The sru_z9350 filter now recognizes SRU parameter z-target as being
1231 a ZURL of the form host/database .
1233 Mergetype may be specified for filter 'multi'.
1235 --- 1.0.12 2007/09/19
1237 Fixed problem in Makefile WRT library specifictions. This could produce
1238 linker errors (when they should not happen).
1240 Fixed bug #1341: MetaProxy returning different results. Problem was that
1241 fix-up of record database did not normalize the database name.
1243 Documentation updates for Windows compilation.
1245 --- 1.0.11 2007/06/14
1247 Fixed problem with logfile being truncated.
1249 --- 1.0.10 2007/05/23
1251 Fixed bug #1136: Access rights not enforced.
1253 Extension for log module. The log category 'access' logs more details.
1254 New category 'user-access' added which is simlar to 'access' but adds
1255 the Z39.50 user as for all entries in a session.
1259 Added support for configurable default/force target/vhost for module Z39.50
1262 --- 1.0.8 2007/01/25
1264 Implemented filter, session_shared, which optimizes usage of Z39.50
1265 sessions and result sets.
1267 New filter, record_transform, which converts MARC/XML records.
1269 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1271 New filter, load_balance, in development.
1273 New filter, zeerex_xplain.
1275 XML framework for config files started.
1277 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1278 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1279 XML config files are checked against RNG and XML Schema's.
1281 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1282 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1283 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1284 explain record to YAZ CQL-to-PQF text config file.
1286 --- 1.0.7 2006/11/07
1288 Added 'timeout' setting for filter frontend_net which specifies the number
1289 of seconds a session is idle before it is closed. Default timeout is
1292 --- 1.0.6 2006/07/07
1294 Database name in records returned set for virt_db/multi filters.
1296 Filter session_shared now functional.
1298 Log filter can be configured to write to a given file using 'filename'
1299 element. Also information category can be specified with 'category'. If
1300 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1303 --- 1.0.5 2006/05/16
1305 Fixed compilation on Windows.
1307 --- 1.0.4 2006/05/16
1309 Added documentation for the hidenavailable option for the multi filter.
1311 --- 1.0.3 2006/05/16
1313 Fixed bug #573: Hide errors for individual servers. If the element
1314 'hideunavailable' is given in the configuration, individual servers
1315 being unavailable are hidden (unless all are unavailable).
1317 Fixed bug #574: Database names are recognised case-sensitively.
1319 Fixed bug #567: Fix up database name in Name-Plus-Record.
1321 Fixed bug #568: Update win/makefile for VS 2005.
1323 Fixed bug #569: Some options throws unknown exception.
1325 --- 1.0.2 2006/04/28
1327 More information about virtual hosts. The 'etc' directory is part of the
1330 --- 1.0.1 2006/04/27
1332 Build instructions for Windows. NMake makefile part of distribution tar.
1334 --- 1.0.0 2006/04/24
1338 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1339 log, multi, query_rewrite, template, virt_db, z3950_client.
1341 Filters in development: session_shared.
1343 Pseudo-filters: template, dl
