7 Fix crash in log filter when record syntax is omitted MP-613
9 Change target z3950.loc.gov:7090/voyager -> lx2.loc.gov:210/LCDB_MARC8
12 Fix Control-C does not stop Metaproxy spawned by shell MP-610
13 Check for fork mode instead (-D) - rather than debug (-X)
17 sru_z3950: allow CCL in SRU search MP-606
18 Makes the sru_z3950 filter convert to CCL queries if query type
19 "ccl" is used, eg ?query=water&queryType=ccl&... for SRU 2.0.
23 Fix dead lock in session_shared (init) MP-605
27 Fix session_shared caches set with diagnostic MP-604
29 Fix assertion failed in session_shared filter MP-603
31 Make /usr/share/metaproxy be part of metaproxy RPM MP-601
33 Log YAZ version upon start MP-599
37 sru_z3950: undo Serialize identical SRU GET requests MP-598
38 Now much more elegantly handled by session_shared.
40 session_shared: anticipated init and search MP-597
42 z3950_client: separate init timeout MP-596
43 Both init-timeout and connect-timeout are configurable by this change.
44 Default is 10 seconds.
48 zoom: support cf_-params MP-595
50 http_client: returns 404 if no destination URI is given
54 zoom: allow / in user and password db args MP-592
58 Log rotate no longer reloads configuration - instead Metaproxy just
59 re-opens log files when SIGHUP is received. MP-485
61 Debian : init.d metaproxy reload should check configuration MP-591
63 Fix Metaproxy stops logging after check config failed MP-590
67 Fix double free in log filter (with incorrect config) MP-589
69 zoom: Add allow_ip feature - fixes MP-588
70 Allow a list of IPs to be given separated by blanks
71 <allow auth_url="http://mkc-admin.indexdata.com/..."
72 allow_ip="127.0.0.1 ::1" .. >
74 cql2pqf.txt: Maps dc.subject to Bib-1 21 rather than 47
76 zoom: fix CS write-check
80 zoom: handle contentAuthentication MP-587
84 Destroy router and filters in parent process MP-584
86 Update NMAKE makefile to use Visual Studio 2013 along with Boost 1.57,
87 ICU 54.1, Libxml2 2.9.2, Libxslt 1.1.28.
91 Use YAZ backtrace facility MP-582
93 Fix libmetaproxy-dev depends on libgnutls-dev - MP-580
94 libgnutls-dev is unavailable on jessie.
96 Update template filter to avoid Pimpl MP-579
98 cgi: POSTed content - part of MP-562
100 Fix filter cgi does not relay session close MP-577
104 Add support for binding outgoing IP for http_client and z3950_client
105 This is enabled by bind_host setting. MP-575
109 z3950_client: allows negotiation charset to be set MP-574
111 cgi: more functional but no support for POSTed content yet (part of MP-564)
113 --- 1.5.11 2014/10/20
115 http_file: add include of sys/stat.h fixes MP-576
117 Fix documentation about SRU client support MP-572
119 Initialize Libxml2 - for threaded operation MP-571
121 --- 1.5.10 2014/08/26
123 On SIGTERM shut down connection+listening sockets MP-568
124 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
128 zoom: make retry on failure configurable MP-565
129 The default and existing behavior is that backend failures (any
130 diagnostic) makes the module re-search once. The behavior may
131 be changed by db parameter 'retry'. If given value '0' disables
132 retry and '1' enables it. If not given, the Torus record may
133 specify with element retryOnFailure (value '0'/'1').
137 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
138 instead of just a child process. Extremely rare in real life, hit me with
139 CF stress testing. MP-559.
143 http_file: passthru option MP-557
144 New facility for http_file to passthru - even if an area is matched. The
145 default behavior (passthru=false) is to return 404: Not found. With
146 passthru=false, next filter is consulted.
150 Fix ref to freed memory in log filter 1line - MP-556
152 echoedSearchRetrieveRequest support MP-555
156 zoom: allow hostname to be given for ipauth MP-552
157 The Torus setting for that is called auth_hostname.
161 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
165 session_shared: close in ~BackendInstance MP-549
166 This fixes a serious issue where some MP would leak sockets.
168 session_shared: mutex lock in BackendClass::release_backend MP-550
169 Fixes a SEGV that could occur (in rare cases).
173 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
175 zoom: fix invalid present response in some cases MP-546
177 zoom: Relay Torus HTTP error message
181 Check for proper limits before using RecordCache functions MP-544
185 Build packages for Ubuntu Trusty Tahr 14.04 LTS
187 sort: crash / invalid_read in filter sort MP-541
189 sru_z3950: facet should be stored in additionalSearchInfo MP-533
191 doc: fix missing man pages MP-542
193 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
195 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
199 sru_z3950: fix facet response (memory corruption) MP-532
201 log: fix crash idPass user is omitted MP-530
205 query_rewrite: pass-thru non Type-1 queries MP-527
207 metaproxy stop (SIGTERM) kills all child processes spanwed by
208 filter (if any) before invoking filter destructors. MP-525
212 http_file: only supports HTTP GET MP-523
214 session_shared: shut down expire thread in destructor
215 This ensures that expire thread is not running after destruction
216 and does bad memory references, etc.
218 frontend_net: fix segfault on startup MP-524
219 Would happen if MP was listening on multiple ports and one
220 of the ports was already in use (and MP would exit).
222 frontend_net: fix memory leak MP-521
223 This leak would occur if all sessions were in use and the input
224 queue was cleared when a client would close connection (socket).
226 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
230 http_rewrite: use local skiplist; fixes memory corruption. MP-520
232 http_client: x-forwarded-for controls X-Forwarded-For presence
233 If x-forwarded-for setting (boolean) is enabled, http_client will
234 generate an X-Forwarded-For header entry which includes existing
235 X-Forwarded-For (if any) and current peer address (immediate client
236 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
237 will not be generated.
239 z3950_client: client_ip controls client-IP presence
240 If client_ip setting (boolean) is enabled, z3950_client will
241 generate a client_ip OID as part of init request which includes
242 previous client_ip (if any) and current peer address (immediate
243 client of Metaproxy). By default client_ip is disabled and client_ip
244 will not be generated.
246 HTTP X-Forwarded-For/Z39.50 Client-IP support
247 virt_db, multi: relays Z39.50 client-IP.
248 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
249 zoom: uses Client-IP or origin address (prefer Client-IP).
250 frontend_net: Strips tcp: from peer address (so that it is no longer
251 printed and stripped in zoom filter).
252 z3950_client: builds client-IP list - combining immediate peer address
253 as returned by COMSTACK and existing client-IP list (if avaiable).
254 The Origin only printes first X-Forwarded address.
258 Log when SIG{TERM,USR1} is received ASAP MP-513
259 Do it in frontend_net event loop rather than in place for metaproxy
260 main, which only exits when all sessions are terminated for SIGUSR1
263 metaproxy-config: quote some RHS values (that might include blanks)
265 Fix leak in sru_z3950 filter - when explain is returned MP-511
267 Allow stylesheet to be given for sru_z3950 filter MP-510
268 This is based on a patch by Sven Porst and the functionality
269 of the YAZ Generic Frontend Server.
271 Allow base attribute in configuration file tags - the attributes are
272 inserted by XInclude usage as mentioned on
273 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
274 and noted in a gist: https://gist.github.com/3551094
276 Package metaproxy provides virtual package metaproxy6 MP-508
277 This allows module packages to depend on a metaproxy server
280 Filter destructors called upon daemon termination MP-505
281 When metaproxy daemon receives SIGTERM the stop method of each filter
282 is called. The stop method existed before, but did not take any
283 arguements (void).. The frontend_net filter can now distinguish
284 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
285 (stop immediately). Note that this changes the API+ABI of Metaproxy
288 zoom: sync up with Pazpar2 WRT authentication handling MP-492
290 Router: use shared_ptr rather than naked one - to avoid leak if an
291 exception is thrown in configure.
295 zoom: Add nocproxy=1 for contentConnector sessions MP-501
297 Doc: mention proper versions; fix link to Boost win binaries.
299 Windows: update for Boost 1.55
301 Windows: avoid warning when using boost::split. Done by defining
302 _SCL_SECURE_NO_WARNINGS for Visual Studio.
304 Fix LSB conformance for /etc/init.d/metaproxy MP-500
305 Debian: add support for /etc/init.d/metaproxy status
307 sort: Add const to Record less than operator in order to compile on
312 session_shared: fix element-set handling in record caching. MP-499
314 document http_rewrite. MP-468
316 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
317 respects the header (which will normally come from the cproxy filter)
321 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
322 RPM was unsable in version 1.4.0.
324 Remove log message about "backend classes". Appeared in version 1.4.0.
328 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
329 with older version from source, but packages now use YAZ 5 that supports
332 sru_z3950: Fix SEGV for decoding invalid SRU requests
333 Incorrect reference to union (was explain response rather than
336 session_shared: match additionalSearchInfo (includes facets). In
337 layman's terms means that means that facets are properly handled
338 by this filter. Eg a change in requested facets will issue new
339 search and facets from exisiting result set are cached.
341 --- 1.3.62 2013/09/11
343 http_rewrite: better handling of <script> content in HTML parser. MP-486
345 http_rewrite: fix threading issue with regex. MP-482
347 bounce: don't use strdup for fixed length content. Error occurred in echo
350 session_shared: expire backend class when no instances left. This
351 means memory clean up, but not really a leak fix.
353 virt_db: fix leak for naked ptr.
355 cql_rpn: use config relative path for cql2rpn file. MP-481
357 Updates for upcoming YAZ 5.
359 --- 1.3.61 2013/08/29
361 New configuration directories ports.d/routes.d for metaproxy
362 configuration. This allows 3rd party packages to install config
363 for ports and new routes. MP-477
365 --- 1.3.60 2013/08/21
367 Fix metaproxy-config --libs to return non-mt over mt libs.
368 The -mt versions do not exist as shared objects and cause
369 linker errors for applications linking with Metaproxy.
370 Problem present in versions 1.3.56 - 1.3.59. MP-475
372 HTML: clean up char checks. Add ptr to HTML parse spec
374 HTML parser stops eating tag when <-char is met MP-473
376 rewrite: do not even compare content types, if we don't have any
377 the regex_match caused a segfault if we had no content-type in the
380 rewrite: within header=... matches only the header value
381 Used to match the whole header line, but we need to use
382 ^$ anchoring for host-relative regexps, and they need to
383 anchor at the ends of the value. MP-470.
385 rewrite: Ruleset functional MP-469
387 --- 1.3.59 2013/07/12
389 session_shared: negotiate init sz parameters.
390 By default, session_shared will honor the paramters given by client.
391 An alternative, but not implemented, algorithm would be to only
392 re-use sessions with same sz parameters. This however, could reduce
393 re-use of sessions a lot. Hence this, simple algorithm instead. The
394 negotiation to a maximum sz values can be enabled by using
395 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
396 in configuration. This will make session_shared send those values
397 to backends and use returned init values in negotaition to
398 client before session_shared.
400 session_shared: resolve result-set references.
401 The reference is substitued with the query for old set if database
402 match and query type is Type-1. If not the reference will issue a
405 sort filter: relays RecordComposition including elementSet in use for
408 http_client: better diagnostics
410 http_client: disables HTTP redirect handling by default.
411 It can be configured with max-redirects in configuration.
413 --- 1.3.58 2013/06/12
415 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
417 --- 1.3.57 2013/06/12
419 Make RouterChain and RouterXML part of public API (libmetaproxy).
421 http_client: honor X-Metaproxy-Proxy as an alternative to
422 the "proxy" configuration. Allows proxy to be set per HTTP request.
424 sru_z3950: For SRU requests recognize x-client prefixes as a way
425 to ingest "database parameters".. The suffix of x-client- serves
426 as database argument name. Multiple may be given. For example:
427 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
428 is turned into Z39.50 database
431 --- 1.3.56 2013/05/27
433 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
435 New filter sd_remove, which replaces surrogate diagnostics with
436 SUTRS records. This filter tries to deal with clients that breaks
437 when receiving surrogate diagnostics.
439 new filter http_client. Same role as z3950_client, but just for
440 HTTP. Allows Metaproxy to operate as a HTTP proxy.
442 New filter http_rewrite1, which serves as purpose on how to rewrite
443 HTTP content with Metaproxy.
445 Use libboost-system if available, because newer versions of libboost-threads
446 requires libboost-system.
448 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
451 --- 1.3.55 2013/04/10
453 zoom: Torus setting: authenticationMode which may hold values "basic"
456 --- 1.3.54 2013/03/27
458 configure: check for Libxslt support in YAZ and rely on definitions
459 from yaz-config, rather than doing own xslt/xml2 checks.
461 Allow timestamp format for log lines to be given with option -m
462 for metaproxy. Similar to yaz-ztest/GFS option -m.
464 Document log category 'line' for log filter.
466 Solr configuration example in etc/config-solr.xml
468 multi: do not mess with request package. For scan and search,
469 database-names were modified and the request package was left with
470 dangling pointers that caused a log filter to fail (request package
471 inspected after multi was invoked).
473 Documentation: fix id of metaproxy-config ref .
475 Documentation: update for USEMARCON support.
477 --- 1.3.53 2013/01/31
479 record_transform: allow OPACXML to OPAC conversion
481 zoom: document content-proxy
483 zoom: document db parm content-{user,password}, torus_url. Also
484 <torus auth_url="..> which makes zoom operate in authenticated mode
487 --- 1.3.52 2012/11/30
489 zoom: fix http://-check. SRU search broken in 1.3.51.
491 --- 1.3.51 2012/11/15
493 zoom: only append http:// for SRU if not already given . Makes it
494 possible to use https-URLs.
496 Use yazpp 1.4 or later due to new ABI.
498 frontend_net: allow max package size to be specified. Controlled by
499 attribute 'max_recv_bytes' of element 'port'.
501 --- 1.3.50 2012/10/29
503 For most generated diagnostics by filters, typically temporary
504 system error, augment addinfo message with filter name.
506 Add support for CentOS 6 packages.
508 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
510 Add man page for metaproxy-config.
512 --- 1.3.49 2012/10/18
514 zoom: new config element passthru. This defines an element set that is
515 passed verbatim to the backend in pz2 mode.
517 auth_simple: allow both idPass and open auth. Also fix SEGV that could
520 --- 1.3.48 2012/10/08
522 z3950_client: fix string handling for init diagnostics in the case where
525 query_rewrite: no charset conversion for error queries. Avoid performing
526 charset conversion for query conversion errors. The resulting Type-1
527 query is invalid in this case.
529 --- 1.3.47 2012/10/04
531 For graceful stop (SIGUSR1), metaproxy will kill children processes.
533 Log when metaproxy is invoked in test mode (-t).
535 Log PID for each log message.
537 multi: combine both NSDs and multiple NSDs into one (diagnostics).
539 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
540 a (backend=target) is appended for each diagnostic so that can be
541 determined the origin of error.
543 multi: hideerrors also in use for present response.
545 Solr example in zoom man page.
547 Fix typo in query_rewrite config example.
549 Log at least first non surrogate diagnostic. Instead of
550 "Z_Records_multipleNSD"
552 multi: Fix check for opt Records in present response. A SEGV could occur
553 if a target did not return records and no diagnostics.
555 --- 1.3.46 2012/09/24
557 Yet another fix for graceful stop.
559 --- 1.3.45 2012/09/12
561 sru_z3950: relay surrogate diagnostics.
563 --- 1.3.44 2012/09/10
565 zoom: Honor extraArgs, strip # in zurl.
567 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
569 zoom: url_recipe allow %{var[reg]} substitutions.
570 It's like ${var[reg]} but does URI component encoding as well.
572 --- 1.3.43 2012/08/22
574 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
575 non-keepalive HTTP sessions.
577 http_file: allow zero size files (bug fix)
579 Fix zoom schema: auth_url is optional
581 --- 1.3.42 2012/08/20
583 zoom: fix un-init memory (could result in SEGV at session close)
585 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
586 and may be used in filters as usual.
588 zoom: authentication via Torus lookup
589 Enabled by new configuration setting: auth_url . If this is defined,
590 the zoom module will contact Torus for auth/IP lookup and that will
591 define realm to be used in session.
593 --- 1.3.41 2012/08/10
595 virt_db: Fix database name - first character we removed by mistake.
596 Bug introduced in 1.3.40.
598 --- 1.3.40 2012/08/06
600 virt_db: Don't use "unix path" as database for Unix sockets.
602 --- 1.3.39 2012/08/02
604 z3950_client: Don't tamper with / in zurl - fixes problems
605 using Unix sockets for backends.
607 session_shared: fix integer overflow problem with hit count.
609 session_shared: avoid long usage of cached queries.
611 zoom: New database argument , torus_url to set URL of Torus
612 record to be fetched.
614 --- 1.3.38 2012/07/04
616 Fixes for 'metaproxy reload' for RPM/Debian packages.
618 zoom: Allow rpn2cql conversion to be augmented with a properties file.
619 Element rpn2cql can be specified per-target for the zoom filter.
621 log: New category "line" which is a single-line log message with
622 most important parts of a HTTP/Z39.50 request/response.
624 --- 1.3.37 2012/06/01
626 frontend_net: add facility to report live statistics about response
627 times and current thread usage. The report is an XML document
628 and is triggered for a specific URL path. This is set by <stat-req>
629 in the configuration of frontend_net. By default this report is
630 disabled (same as empty value for <stat-req>).
632 Fix reload problem in init.d script for RPM/Debian.
633 The '/etc/init.d/metaproxy reload' in some cases would stop but not
634 start metaproxy - effectively stopping the service.
636 Don't display start log message when config testing (-t).
638 zoom: avoid CCL message limit of 1K in ZOOM filter.
640 --- 1.3.36 2012/05/10
642 metaproxy init script reacts to reload which does graceful stop +
643 start and is used by logrorate script.
645 --- 1.3.35 2012/05/09
647 Fixes for Windows compilation.
649 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
650 existing sessions running but terminate the monitor process that is
651 used in keepalive mode.
653 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
654 before. Consistent with 'metaproxy stop' message.
656 zoom: document zoom's proxy_timeout
658 z3950_client: fixup addinfo for init response
660 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
661 "Access to specified database denied" is returned, but only if init
662 response from backend does not carry diagnostics already.
664 multi: relays user info for first rejected target. The other-information
665 field for init response for first rejected target is in common init
666 response. This ensures that some backend init diagnostics are returned to
669 --- 1.3.34 2012/04/25
671 frontend_log: extend logging (when message is given in config).
673 --- 1.3.33 2012/04/25
675 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
677 --- 1.3.32 2012/04/24
679 sru_z3950 filter passes through incoming Z39.50 requests again. Was
680 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
682 --- 1.3.31 2012/04/24
684 zoom: fixes for retry/proxy failover logic. More logging.
686 --- 1.3.30 2012/04/23
688 zoom: return addinfo="proxy failure" for proxy failures. This also
689 changes the scheme for dealing with proxies a bit. zoom now always
690 do proxy check, even if there's no failover. Fortunately, that's not
693 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
694 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
695 generic. We don't know why the init would fail; IP, user, block IP, etc.
696 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
698 zoom: guess if invalid SRU response was an auth failure
700 session_shared: disable session retry by default . Can be enabled by
701 restart="true" in resultset section.
703 --- 1.3.29 2012/04/18
705 zoom: may read cf-proxy's config settings.
706 This reduces manual configuration of the content proxy server host.
707 The ZOOM module will use the old style session.proxyhost if "server"
708 is given (deprecated) and use the new style proxyhost/session if
709 "config_file" is in use.
711 frontend_net: remove incoming requests that can not be handled
712 Requests in queue for filter frontend_net are removed if client
713 closes connection for the session and request is not yet handled.
715 sru_z3950: serialize requests. This is to ensure that pipelined
716 HTTP requests are handled properly.
718 --- 1.3.28 2012/04/04
720 New class, wrbuf, that wraps YAZ' WRBUF.
722 --- 1.3.27 2012/03/30
724 Metaproxy daemon is now running as user "metaproxy". This user is
725 managed by package maintainer scripts. The user information is stored
726 in /etc/metaproxy/metaproxy.user .
728 --- 1.3.26 2012/03/20
730 New filter, sort, that allows sorting of XML records via Z39.50
733 Filter record_transform: USEMarcon support. For example:
734 <retrieval syntax="usmarc">
735 <backend syntax="unimarc" name="F">
736 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
740 Filter multi: empty route pattern uses route as default.
742 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
743 may use the shorter notation
744 <target route="z3950.indexdata.com"/>
746 Filter query_rewrite: use config path to locate XSLT.
748 Filter frontend_net: log statistics.
749 If a custom message element in frontend_net configuration it makes
750 the frontend_net filter produce a log entry whenever an operation
751 is completed. The log is always written using yaz_log with the
752 custom message given, the package ID (session ID) , the time
753 the operation has been active (end-to-end) , the threads currently
754 active/total and the size of the request input/output queues.
756 query_rewrite: charset conversion of query terms.
757 This is an optional feature. Enabled by element <charset> in
758 configuration with attribute 'from' and 'to' that specifies
759 from/to encodings. The default 'from' encoding is UTF-8.
761 Filter record_transform: honor piggyback searches.
763 Filter zoom: re-connect when database is reused.
764 Re-connect is necessary if a connection is lost or a timeout occurs.
765 If not, we'll be seeing zero hits, when we shouldn't.
767 --- 1.3.25 2012/02/29
769 zoom: Change scheme for dealing with content proxy URLs. The module
770 now has its own common XSL transform that is enabled by record_xsl
771 attribute in the configuration. This XSL gets parameter cproxyhost
772 that holds the host for the content proxy session . The genearted-url
773 is created only if urlRecipe is enabled. In previous version default
774 value of urlRecipe was ${md-electronic-url}; it is now empty and
775 disabled by default. Also generated-url no longer includes the content
776 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
779 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
780 connections. Default value is 40 (seconds).
782 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
783 "Malformed query" for syntax errors and related ones; throw
784 Bib-1: 3 "Unsupported search" for everything else. Details from
785 the CCL parser is provided as additional-info.
787 multi: new setting hideerrors that makes multi only relay diagnostics
788 to a client if all backends fail.
790 --- 1.3.24 2012/02/23
792 zoom: empty ccl_map field-mappings disables CCL map.
794 zoom: fix Explain search that could return error if session was
797 --- 1.3.23 2012/02/10
799 zoom: returns Explain records for database IR-Explain---1. The
800 target profile records are converted to Explain records via XSLT.
802 session_shared: make error recovery configurable. Whether a search
803 is restarted on errors or not, is configurable by attribute "restart"
804 in element "resultset" in configuration.
806 session_shared: only relay init for first request. session_shared, for
807 each backend class, now only relays first init request (rather than all).
808 The module only needs to save init response info once. This avoids the
809 need to check for session max.
811 --- 1.3.22 2012/02/02
813 zoom: fix memory leaks.
815 session_shared: maximum number of sessons is configurable. Default
816 value is 100. Result-sets for backends without named result sets are
817 only re-used if databases is identical for a search. This is under the
818 assumption that performance may suffer for those backends when
819 changing the database for each search.
821 multi: combines diagnostics from all backends. All diagnostics from
822 backends are combined into multiple non-surrogate diagnostics; rather
823 than just one diagnostic from first backend.
825 --- 1.3.21 2011/12/27
827 zoom: relay realm to cproxy parameter file.
829 Configuration: Allow filter collection element inside route. This
830 makes it possible to include multiple filters at once.
832 zoom: nocproxy also disables urlRecipe.
834 --- 1.3.20 2011/12/21
836 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
837 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
838 90: "Unsupported direction value".
840 zoom: honor database argument nocproxy. This disables creating a content
841 connector session (for non-CF targets, usually) and also relays nocproxy
842 as database argument to a CF target.
844 --- 1.3.19 2011/12/16
846 zoom: Multiple proxy hosts may be given for proxy rich database
847 parameter. List is comma separated.
849 http_file: decodes URI paths properly. Does not return 404: not found
850 if no prefix are matches. Instead packages are passed on.
852 --- 1.3.18 2011/12/08
854 zoom: content-{user,password,proxy} are passed on to content proxy
855 system and takes precedence over user,password,proxy .
857 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
858 with a log element including log material from children filters. At
859 this point, only the zoom filter uses this log facility. It will
860 eventually be used by other filters as well. In particular it might be
861 useful for this feature to track all filters in used during a search.
863 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
864 and queries as they are manipulated are logged.
866 zoom: extend addinfo with native diagnostics. Diagnostics as received
867 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
868 diagnostics. This indicates both a backend diagnostic and the original
871 zoom: default urlRecipe value is ${md-electronic-url}
873 zoom: target profile setting sruVersion is recognized.
875 --- 1.3.17 2011/11/17
877 zoom: log target profile record fetched (AKA Torus).
879 --- 1.3.16 2011/11/17
881 Change target profile parameter CfSubDb to CfSubDB.
883 --- 1.3.15 2011/11/12
885 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
886 makes sense to the zoom module itself).
888 --- 1.3.14 2011/11/11
890 zoom: realm may be given as part of database.
892 --- 1.3.13 2011/10/26
894 Fix Origin class assigment method; was removd by mistake in 1.3.12.
896 --- 1.3.12 2011/10/26
898 zoom: database args x-name=value are passed through to backend database.
900 SRU filter: user may specify session ID that is passed to log entries
901 that follows. It is specified by using x-session-id in the SRU arguments.
903 zoom: fix null pointer reference which would occur for bad url parameter
904 inside "torus" or if url was not given.
906 --- 1.3.11 2011/09/09
907 Fix bug in filter session_shared where sessions would not expire
908 properly (session ttl). This in turn could make the target close the
909 connection before expected and session_shared would return diagnostic
910 2: system temporarily available.
912 --- 1.3.10 2011/09/09
914 zoom: new target profile setting: sortmap_field. If sortmap_field is given
915 the field is mapped to the value for the sortmap. Values not matching
916 sortmap_field are passed verbatim.
918 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
919 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
920 depending on whether RPN or CQL is actually sent to the target.
924 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
926 zoom: For content proxy authentication is stored in param name
927 "auth", instead of "authentication".
931 zoom: relay schema in SRU mode. Previously recordSchema was not affected
936 zoom: new target profile element literalTransform that holds XSLT
937 (encoded as string) for target. Only if present and non-zero length it is
938 considered present. This takes precedence over transform.
940 Don't rely on trang anymore for Git checkout builds. Configuration in etc
941 will only be properly validated if trang is available. From now on only
942 relax NC files are bundled with the source dist.
944 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
945 component was not detected when it should be.
949 z3950_client: mark non-surrogate diagnostics from backend.
951 zoom: a proxy may be specified for HTTP fetch of target profiles.
955 Honor piggyback. Makes some SRU targets behave that insist on
956 maximumRecords > 0, but also increases performance.
960 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
961 file was not update for libdir/metaproxy4 in version 1.3.2.
965 Change location of Metaproxy modules from libdir/metaproxy to
966 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
967 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
969 New facility to dump APDUs from zoom filter. Enabled by
970 <log apdu="true"/> in the zoom filter configuation.
972 zoom filter bug fix: SRU diagnostics received from backend was
973 not properly converted to Bib-1 diagnostics.
975 Package metaproxy depends on libmetaproxy4, same version.
979 zoom: fix a bug WRT passing authentication parameters to backends.
983 Fixes for windows Makefile.
985 --- 1.2.10 2011/07/25
987 Change major version of metaproxy library from 3 to 4. This in turn
988 makes new package names for Debian and RPM.
992 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
995 zoom: configurable element sets for record transforms.
997 zoom: the target profile based transform is specified by element_transform
998 in element torus of of the ZOOM filter configuration ; default value
999 is "pz2". Target profile based retrieval is specified by element_raw
1000 in configuration. It will perform same steps, but omit the XSL transform.
1001 Default value is "raw".
1003 zoom: element set is omitted if not set in profile. But only if pz2
1004 transform is in effect. Previously the default element set was to "F".
1006 zoom: For non-CF targets database arguments are parsed. User may supply
1007 db,user=myuser&password=mypass for non-CF targets. These values override
1008 what's given the authentication from the target profile.
1010 session_shared: fix reference to freed memory. Would occur if a search
1011 response had non-surrogate diagnostics.
1013 --- 1.2.8 2011/06/22
1015 Route may be given for each port in frontend_net.
1017 --- 1.2.7 2011/06/22
1019 Documentation for zoom filter. Local target profiles may be specified.
1021 Fixes for zoom filter.
1023 --- 1.2.6 2011/06/15
1025 First version with zoom filter.
1027 --- 1.2.5 2011/05/06
1029 Filter z3950_client may be configured to always send a close APDU
1030 to backend target when connection/session is closed. This will only
1031 happen if close APDU is not already sent. Enabled by configuration
1032 for z3950_client (force_close).
1034 Filter virt_db and multi: relay close APDU.
1036 Filter virt_db and multi: relay init size parameters
1037 preferredMessageSize and maximumRecordSize.
1039 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
1041 --- 1.2.4 2011/01/27
1043 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
1045 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
1046 as determined by configure.
1048 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1049 this package can be distinguished from other vendors.
1051 --- 1.2.3 2010/10/04
1053 Fix filter multi: relay idAuthentication parameters.
1055 --- 1.2.2 2010/09/15
1057 Add metaproxy-config for returning compiler flags, libraries.
1059 --- 1.2.1 2010/08/18
1061 Fix --with-boost=PREFIX .
1063 --- 1.2.0 2010/07/09
1065 session_shared: fix use of maintenance thread.
1067 Introduce 'start' method for filters and routers. It gets called after
1068 configure and after fork, but before processing. This changes API -
1069 from libmetaproxy2 to libmetaproxy3.
1071 --- 1.1.7 2010/06/30
1073 session_shared: ensure backend session is closed if init rejected
1076 z3950_client: fix NULL ptr reference that could occur if two clients
1077 connected concurrently and if max-sockets was in effect.
1079 --- 1.1.6 2010/06/21
1081 Fix bug 3497 - Metaproxy unstable while stopping.
1083 Fix bug 3495 - SEGV in SRU filter.
1085 --- 1.1.5 2010/06/15
1087 Filter multi throws diagnostic 'Present Out of Range' when
1088 appropriate - rather than returning 0 records.
1090 Filter virt_db: fix bad result reuse. Could happen if a result
1091 was overriden and a backend did not supported named result sets.
1093 --- 1.1.4 2010/05/11
1095 Filter log: category access logs diagnostics even if searchStatus
1096 or presentStatus is 'success'.
1098 --- 1.1.3 2010/04/21
1100 The SRU to Z39.50 filter does repeated Z39.50 present requests
1101 to fetch all records. Needed when a Z39.50 server returns partial
1102 results (due to message size limits).
1104 --- 1.1.2 2010/03/18
1106 Metaproxy now kills all child processes that are spawned by
1107 modules (in case of fork, exec).
1109 --- 1.1.1 2010/01/28
1111 Debian package now installs /etc/metaproxy/metaproxy.xml which
1112 includes all XML files /etc/metaproxy/filters-enabled .
1113 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1115 --- 1.1.0 2010/01/20
1117 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1118 development package to facilitate 3rd party Metaproxy modules.
1120 --- 1.0.23 2010/01/04
1122 Filter virt_db: Close backend filter session when Init rejected is received
1123 from it (in which case it's not really closed yet). This will ensure we don't
1124 run out of resources such as FDs in this case.
1126 sru_z3950 filter: Accept any database (including those not listed).
1128 --- 1.0.22 2009/12/03
1130 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1131 later which means YAZ 3.0.47 or later.
1133 --- 1.0.20 2009/11/19
1135 For filter virt_db, the database is a glob pattern and the virtual
1136 database sections are consulted in the order given.
1138 --- 1.0.19 2009/07/08
1140 For filter multi, the target (for routing) may be given as a glob-pattern.
1142 More documentation for filters virt_db and multi.
1144 Update schema to allow for no database in sru_z3950 filter.
1146 --- 1.0.18 2009/06/30
1148 Added limit filter to put sleep (penalty) for heavy use.
1150 Filter frontend_net may be configured to limit the number of new connections
1151 from same IP to some value (connect-max).
1153 Fixed the load_balance filter.
1155 --- 1.0.17 2009/06/16
1157 Fix path for metaproxy executable for Debian init.d script.
1159 --- 1.0.16 2009/06/10
1161 SRU to Z39.50 filter honors x-username and x-password. If only
1162 x-username is given that translates to open authentication (Z39.50v2). If
1163 both x-username and x-password is present that translates to idPass
1164 authentication (Z39.50v3).
1166 New facility to change current working directory (-w).
1168 Update to upstream skeleton of init.d script. Should fix bug #2619.
1170 Filter session_shared now caches records (used to only cache connections
1173 Filter session_shared now invalidates a Z39.50 session if a server
1174 returns -1 hits. This facility was also part of yazproxy and gets around
1175 a bug in Voyager-based Z39.50 servers.
1177 --- 1.0.15 2008/11/18
1179 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1181 --- 1.0.14 2008/06/09
1183 Fixed the value of SRU record schema in searchRetrieve response. It was set
1184 to a fixed value of "dc" before.
1186 Serialize identical SRU requests. This is useful if HTTP client software
1187 fires identical requests against metaproxy.
1189 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1190 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1191 avoid static configuration. This facility is handled by the sru_z3950 module
1192 and the z3950_client module.
1194 Allow maximum number of sockets to be used for a Z39.50 client by the
1195 use of SRU extra parameter x-max-sockets. This facility is handled by the
1196 sru_z3950 module and the z3950_client module.
1198 --- 1.0.13.1 2008/02/29
1200 Simplified check for Boost libraries.
1202 --- 1.0.13 2008/02/29
1204 First Debian package.
1206 The sru_z9350 filter now recognizes SRU parameter z-target as being
1207 a ZURL of the form host/database .
1209 Mergetype may be specified for filter 'multi'.
1211 --- 1.0.12 2007/09/19
1213 Fixed problem in Makefile WRT library specifictions. This could produce
1214 linker errors (when they should not happen).
1216 Fixed bug #1341: MetaProxy returning different results. Problem was that
1217 fix-up of record database did not normalize the database name.
1219 Documentation updates for Windows compilation.
1221 --- 1.0.11 2007/06/14
1223 Fixed problem with logfile being truncated.
1225 --- 1.0.10 2007/05/23
1227 Fixed bug #1136: Access rights not enforced.
1229 Extension for log module. The log category 'access' logs more details.
1230 New category 'user-access' added which is simlar to 'access' but adds
1231 the Z39.50 user as for all entries in a session.
1235 Added support for configurable default/force target/vhost for module Z39.50
1238 --- 1.0.8 2007/01/25
1240 Implemented filter, session_shared, which optimizes usage of Z39.50
1241 sessions and result sets.
1243 New filter, record_transform, which converts MARC/XML records.
1245 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1247 New filter, load_balance, in development.
1249 New filter, zeerex_xplain.
1251 XML framework for config files started.
1253 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1254 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1255 XML config files are checked against RNG and XML Schema's.
1257 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1258 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1259 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1260 explain record to YAZ CQL-to-PQF text config file.
1262 --- 1.0.7 2006/11/07
1264 Added 'timeout' setting for filter frontend_net which specifies the number
1265 of seconds a session is idle before it is closed. Default timeout is
1268 --- 1.0.6 2006/07/07
1270 Database name in records returned set for virt_db/multi filters.
1272 Filter session_shared now functional.
1274 Log filter can be configured to write to a given file using 'filename'
1275 element. Also information category can be specified with 'category'. If
1276 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1279 --- 1.0.5 2006/05/16
1281 Fixed compilation on Windows.
1283 --- 1.0.4 2006/05/16
1285 Added documentation for the hidenavailable option for the multi filter.
1287 --- 1.0.3 2006/05/16
1289 Fixed bug #573: Hide errors for individual servers. If the element
1290 'hideunavailable' is given in the configuration, individual servers
1291 being unavailable are hidden (unless all are unavailable).
1293 Fixed bug #574: Database names are recognised case-sensitively.
1295 Fixed bug #567: Fix up database name in Name-Plus-Record.
1297 Fixed bug #568: Update win/makefile for VS 2005.
1299 Fixed bug #569: Some options throws unknown exception.
1301 --- 1.0.2 2006/04/28
1303 More information about virtual hosts. The 'etc' directory is part of the
1306 --- 1.0.1 2006/04/27
1308 Build instructions for Windows. NMake makefile part of distribution tar.
1310 --- 1.0.0 2006/04/24
1314 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1315 log, multi, query_rewrite, template, virt_db, z3950_client.
1317 Filters in development: session_shared.
1319 Pseudo-filters: template, dl
