3 zoom: support cf_-params MP-595
5 http_client: returns 404 if no destination URI is given
9 zoom: allow / in user and password db args MP-592
13 Log rotate no longer reloads configuration - instead Metaproxy just
14 re-opens log files when SIGHUP is received. MP-485
16 Debian : init.d metaproxy reload should check configuration MP-591
18 Fix Metaproxy stops logging after check config failed MP-590
22 Fix double free in log filter (with incorrect config) MP-589
24 zoom: Add allow_ip feature - fixes MP-588
25 Allow a list of IPs to be given separated by blanks
26 <allow auth_url="http://mkc-admin.indexdata.com/..."
27 allow_ip="127.0.0.1 ::1" .. >
29 cql2pqf.txt: Maps dc.subject to Bib-1 21 rather than 47
31 zoom: fix CS write-check
35 zoom: handle contentAuthentication MP-587
39 Destroy router and filters in parent process MP-584
41 Update NMAKE makefile to use Visual Studio 2013 along with Boost 1.57,
42 ICU 54.1, Libxml2 2.9.2, Libxslt 1.1.28.
46 Use YAZ backtrace facility MP-582
48 Fix libmetaproxy-dev depends on libgnutls-dev - MP-580
49 libgnutls-dev is unavailable on jessie.
51 Update template filter to avoid Pimpl MP-579
53 cgi: POSTed content - part of MP-562
55 Fix filter cgi does not relay session close MP-577
59 Add support for binding outgoing IP for http_client and z3950_client
60 This is enabled by bind_host setting. MP-575
64 z3950_client: allows negotiation charset to be set MP-574
66 cgi: more functional but no support for POSTed content yet (part of MP-564)
70 http_file: add include of sys/stat.h fixes MP-576
72 Fix documentation about SRU client support MP-572
74 Initialize Libxml2 - for threaded operation MP-571
78 On SIGTERM shut down connection+listening sockets MP-568
79 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
83 zoom: make retry on failure configurable MP-565
84 The default and existing behavior is that backend failures (any
85 diagnostic) makes the module re-search once. The behavior may
86 be changed by db parameter 'retry'. If given value '0' disables
87 retry and '1' enables it. If not given, the Torus record may
88 specify with element retryOnFailure (value '0'/'1').
92 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
93 instead of just a child process. Extremely rare in real life, hit me with
94 CF stress testing. MP-559.
98 http_file: passthru option MP-557
99 New facility for http_file to passthru - even if an area is matched. The
100 default behavior (passthru=false) is to return 404: Not found. With
101 passthru=false, next filter is consulted.
105 Fix ref to freed memory in log filter 1line - MP-556
107 echoedSearchRetrieveRequest support MP-555
111 zoom: allow hostname to be given for ipauth MP-552
112 The Torus setting for that is called auth_hostname.
116 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
120 session_shared: close in ~BackendInstance MP-549
121 This fixes a serious issue where some MP would leak sockets.
123 session_shared: mutex lock in BackendClass::release_backend MP-550
124 Fixes a SEGV that could occur (in rare cases).
128 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
130 zoom: fix invalid present response in some cases MP-546
132 zoom: Relay Torus HTTP error message
136 Check for proper limits before using RecordCache functions MP-544
140 Build packages for Ubuntu Trusty Tahr 14.04 LTS
142 sort: crash / invalid_read in filter sort MP-541
144 sru_z3950: facet should be stored in additionalSearchInfo MP-533
146 doc: fix missing man pages MP-542
148 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
150 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
154 sru_z3950: fix facet response (memory corruption) MP-532
156 log: fix crash idPass user is omitted MP-530
160 query_rewrite: pass-thru non Type-1 queries MP-527
162 metaproxy stop (SIGTERM) kills all child processes spanwed by
163 filter (if any) before invoking filter destructors. MP-525
167 http_file: only supports HTTP GET MP-523
169 session_shared: shut down expire thread in destructor
170 This ensures that expire thread is not running after destruction
171 and does bad memory references, etc.
173 frontend_net: fix segfault on startup MP-524
174 Would happen if MP was listening on multiple ports and one
175 of the ports was already in use (and MP would exit).
177 frontend_net: fix memory leak MP-521
178 This leak would occur if all sessions were in use and the input
179 queue was cleared when a client would close connection (socket).
181 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
185 http_rewrite: use local skiplist; fixes memory corruption. MP-520
187 http_client: x-forwarded-for controls X-Forwarded-For presence
188 If x-forwarded-for setting (boolean) is enabled, http_client will
189 generate an X-Forwarded-For header entry which includes existing
190 X-Forwarded-For (if any) and current peer address (immediate client
191 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
192 will not be generated.
194 z3950_client: client_ip controls client-IP presence
195 If client_ip setting (boolean) is enabled, z3950_client will
196 generate a client_ip OID as part of init request which includes
197 previous client_ip (if any) and current peer address (immediate
198 client of Metaproxy). By default client_ip is disabled and client_ip
199 will not be generated.
201 HTTP X-Forwarded-For/Z39.50 Client-IP support
202 virt_db, multi: relays Z39.50 client-IP.
203 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
204 zoom: uses Client-IP or origin address (prefer Client-IP).
205 frontend_net: Strips tcp: from peer address (so that it is no longer
206 printed and stripped in zoom filter).
207 z3950_client: builds client-IP list - combining immediate peer address
208 as returned by COMSTACK and existing client-IP list (if avaiable).
209 The Origin only printes first X-Forwarded address.
213 Log when SIG{TERM,USR1} is received ASAP MP-513
214 Do it in frontend_net event loop rather than in place for metaproxy
215 main, which only exits when all sessions are terminated for SIGUSR1
218 metaproxy-config: quote some RHS values (that might include blanks)
220 Fix leak in sru_z3950 filter - when explain is returned MP-511
222 Allow stylesheet to be given for sru_z3950 filter MP-510
223 This is based on a patch by Sven Porst and the functionality
224 of the YAZ Generic Frontend Server.
226 Allow base attribute in configuration file tags - the attributes are
227 inserted by XInclude usage as mentioned on
228 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
229 and noted in a gist: https://gist.github.com/3551094
231 Package metaproxy provides virtual package metaproxy6 MP-508
232 This allows module packages to depend on a metaproxy server
235 Filter destructors called upon daemon termination MP-505
236 When metaproxy daemon receives SIGTERM the stop method of each filter
237 is called. The stop method existed before, but did not take any
238 arguements (void).. The frontend_net filter can now distinguish
239 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
240 (stop immediately). Note that this changes the API+ABI of Metaproxy
243 zoom: sync up with Pazpar2 WRT authentication handling MP-492
245 Router: use shared_ptr rather than naked one - to avoid leak if an
246 exception is thrown in configure.
250 zoom: Add nocproxy=1 for contentConnector sessions MP-501
252 Doc: mention proper versions; fix link to Boost win binaries.
254 Windows: update for Boost 1.55
256 Windows: avoid warning when using boost::split. Done by defining
257 _SCL_SECURE_NO_WARNINGS for Visual Studio.
259 Fix LSB conformance for /etc/init.d/metaproxy MP-500
260 Debian: add support for /etc/init.d/metaproxy status
262 sort: Add const to Record less than operator in order to compile on
267 session_shared: fix element-set handling in record caching. MP-499
269 document http_rewrite. MP-468
271 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
272 respects the header (which will normally come from the cproxy filter)
276 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
277 RPM was unsable in version 1.4.0.
279 Remove log message about "backend classes". Appeared in version 1.4.0.
283 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
284 with older version from source, but packages now use YAZ 5 that supports
287 sru_z3950: Fix SEGV for decoding invalid SRU requests
288 Incorrect reference to union (was explain response rather than
291 session_shared: match additionalSearchInfo (includes facets). In
292 layman's terms means that means that facets are properly handled
293 by this filter. Eg a change in requested facets will issue new
294 search and facets from exisiting result set are cached.
296 --- 1.3.62 2013/09/11
298 http_rewrite: better handling of <script> content in HTML parser. MP-486
300 http_rewrite: fix threading issue with regex. MP-482
302 bounce: don't use strdup for fixed length content. Error occurred in echo
305 session_shared: expire backend class when no instances left. This
306 means memory clean up, but not really a leak fix.
308 virt_db: fix leak for naked ptr.
310 cql_rpn: use config relative path for cql2rpn file. MP-481
312 Updates for upcoming YAZ 5.
314 --- 1.3.61 2013/08/29
316 New configuration directories ports.d/routes.d for metaproxy
317 configuration. This allows 3rd party packages to install config
318 for ports and new routes. MP-477
320 --- 1.3.60 2013/08/21
322 Fix metaproxy-config --libs to return non-mt over mt libs.
323 The -mt versions do not exist as shared objects and cause
324 linker errors for applications linking with Metaproxy.
325 Problem present in versions 1.3.56 - 1.3.59. MP-475
327 HTML: clean up char checks. Add ptr to HTML parse spec
329 HTML parser stops eating tag when <-char is met MP-473
331 rewrite: do not even compare content types, if we don't have any
332 the regex_match caused a segfault if we had no content-type in the
335 rewrite: within header=... matches only the header value
336 Used to match the whole header line, but we need to use
337 ^$ anchoring for host-relative regexps, and they need to
338 anchor at the ends of the value. MP-470.
340 rewrite: Ruleset functional MP-469
342 --- 1.3.59 2013/07/12
344 session_shared: negotiate init sz parameters.
345 By default, session_shared will honor the paramters given by client.
346 An alternative, but not implemented, algorithm would be to only
347 re-use sessions with same sz parameters. This however, could reduce
348 re-use of sessions a lot. Hence this, simple algorithm instead. The
349 negotiation to a maximum sz values can be enabled by using
350 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
351 in configuration. This will make session_shared send those values
352 to backends and use returned init values in negotaition to
353 client before session_shared.
355 session_shared: resolve result-set references.
356 The reference is substitued with the query for old set if database
357 match and query type is Type-1. If not the reference will issue a
360 sort filter: relays RecordComposition including elementSet in use for
363 http_client: better diagnostics
365 http_client: disables HTTP redirect handling by default.
366 It can be configured with max-redirects in configuration.
368 --- 1.3.58 2013/06/12
370 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
372 --- 1.3.57 2013/06/12
374 Make RouterChain and RouterXML part of public API (libmetaproxy).
376 http_client: honor X-Metaproxy-Proxy as an alternative to
377 the "proxy" configuration. Allows proxy to be set per HTTP request.
379 sru_z3950: For SRU requests recognize x-client prefixes as a way
380 to ingest "database parameters".. The suffix of x-client- serves
381 as database argument name. Multiple may be given. For example:
382 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
383 is turned into Z39.50 database
386 --- 1.3.56 2013/05/27
388 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
390 New filter sd_remove, which replaces surrogate diagnostics with
391 SUTRS records. This filter tries to deal with clients that breaks
392 when receiving surrogate diagnostics.
394 new filter http_client. Same role as z3950_client, but just for
395 HTTP. Allows Metaproxy to operate as a HTTP proxy.
397 New filter http_rewrite1, which serves as purpose on how to rewrite
398 HTTP content with Metaproxy.
400 Use libboost-system if available, because newer versions of libboost-threads
401 requires libboost-system.
403 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
406 --- 1.3.55 2013/04/10
408 zoom: Torus setting: authenticationMode which may hold values "basic"
411 --- 1.3.54 2013/03/27
413 configure: check for Libxslt support in YAZ and rely on definitions
414 from yaz-config, rather than doing own xslt/xml2 checks.
416 Allow timestamp format for log lines to be given with option -m
417 for metaproxy. Similar to yaz-ztest/GFS option -m.
419 Document log category 'line' for log filter.
421 Solr configuration example in etc/config-solr.xml
423 multi: do not mess with request package. For scan and search,
424 database-names were modified and the request package was left with
425 dangling pointers that caused a log filter to fail (request package
426 inspected after multi was invoked).
428 Documentation: fix id of metaproxy-config ref .
430 Documentation: update for USEMARCON support.
432 --- 1.3.53 2013/01/31
434 record_transform: allow OPACXML to OPAC conversion
436 zoom: document content-proxy
438 zoom: document db parm content-{user,password}, torus_url. Also
439 <torus auth_url="..> which makes zoom operate in authenticated mode
442 --- 1.3.52 2012/11/30
444 zoom: fix http://-check. SRU search broken in 1.3.51.
446 --- 1.3.51 2012/11/15
448 zoom: only append http:// for SRU if not already given . Makes it
449 possible to use https-URLs.
451 Use yazpp 1.4 or later due to new ABI.
453 frontend_net: allow max package size to be specified. Controlled by
454 attribute 'max_recv_bytes' of element 'port'.
456 --- 1.3.50 2012/10/29
458 For most generated diagnostics by filters, typically temporary
459 system error, augment addinfo message with filter name.
461 Add support for CentOS 6 packages.
463 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
465 Add man page for metaproxy-config.
467 --- 1.3.49 2012/10/18
469 zoom: new config element passthru. This defines an element set that is
470 passed verbatim to the backend in pz2 mode.
472 auth_simple: allow both idPass and open auth. Also fix SEGV that could
475 --- 1.3.48 2012/10/08
477 z3950_client: fix string handling for init diagnostics in the case where
480 query_rewrite: no charset conversion for error queries. Avoid performing
481 charset conversion for query conversion errors. The resulting Type-1
482 query is invalid in this case.
484 --- 1.3.47 2012/10/04
486 For graceful stop (SIGUSR1), metaproxy will kill children processes.
488 Log when metaproxy is invoked in test mode (-t).
490 Log PID for each log message.
492 multi: combine both NSDs and multiple NSDs into one (diagnostics).
494 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
495 a (backend=target) is appended for each diagnostic so that can be
496 determined the origin of error.
498 multi: hideerrors also in use for present response.
500 Solr example in zoom man page.
502 Fix typo in query_rewrite config example.
504 Log at least first non surrogate diagnostic. Instead of
505 "Z_Records_multipleNSD"
507 multi: Fix check for opt Records in present response. A SEGV could occur
508 if a target did not return records and no diagnostics.
510 --- 1.3.46 2012/09/24
512 Yet another fix for graceful stop.
514 --- 1.3.45 2012/09/12
516 sru_z3950: relay surrogate diagnostics.
518 --- 1.3.44 2012/09/10
520 zoom: Honor extraArgs, strip # in zurl.
522 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
524 zoom: url_recipe allow %{var[reg]} substitutions.
525 It's like ${var[reg]} but does URI component encoding as well.
527 --- 1.3.43 2012/08/22
529 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
530 non-keepalive HTTP sessions.
532 http_file: allow zero size files (bug fix)
534 Fix zoom schema: auth_url is optional
536 --- 1.3.42 2012/08/20
538 zoom: fix un-init memory (could result in SEGV at session close)
540 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
541 and may be used in filters as usual.
543 zoom: authentication via Torus lookup
544 Enabled by new configuration setting: auth_url . If this is defined,
545 the zoom module will contact Torus for auth/IP lookup and that will
546 define realm to be used in session.
548 --- 1.3.41 2012/08/10
550 virt_db: Fix database name - first character we removed by mistake.
551 Bug introduced in 1.3.40.
553 --- 1.3.40 2012/08/06
555 virt_db: Don't use "unix path" as database for Unix sockets.
557 --- 1.3.39 2012/08/02
559 z3950_client: Don't tamper with / in zurl - fixes problems
560 using Unix sockets for backends.
562 session_shared: fix integer overflow problem with hit count.
564 session_shared: avoid long usage of cached queries.
566 zoom: New database argument , torus_url to set URL of Torus
567 record to be fetched.
569 --- 1.3.38 2012/07/04
571 Fixes for 'metaproxy reload' for RPM/Debian packages.
573 zoom: Allow rpn2cql conversion to be augmented with a properties file.
574 Element rpn2cql can be specified per-target for the zoom filter.
576 log: New category "line" which is a single-line log message with
577 most important parts of a HTTP/Z39.50 request/response.
579 --- 1.3.37 2012/06/01
581 frontend_net: add facility to report live statistics about response
582 times and current thread usage. The report is an XML document
583 and is triggered for a specific URL path. This is set by <stat-req>
584 in the configuration of frontend_net. By default this report is
585 disabled (same as empty value for <stat-req>).
587 Fix reload problem in init.d script for RPM/Debian.
588 The '/etc/init.d/metaproxy reload' in some cases would stop but not
589 start metaproxy - effectively stopping the service.
591 Don't display start log message when config testing (-t).
593 zoom: avoid CCL message limit of 1K in ZOOM filter.
595 --- 1.3.36 2012/05/10
597 metaproxy init script reacts to reload which does graceful stop +
598 start and is used by logrorate script.
600 --- 1.3.35 2012/05/09
602 Fixes for Windows compilation.
604 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
605 existing sessions running but terminate the monitor process that is
606 used in keepalive mode.
608 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
609 before. Consistent with 'metaproxy stop' message.
611 zoom: document zoom's proxy_timeout
613 z3950_client: fixup addinfo for init response
615 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
616 "Access to specified database denied" is returned, but only if init
617 response from backend does not carry diagnostics already.
619 multi: relays user info for first rejected target. The other-information
620 field for init response for first rejected target is in common init
621 response. This ensures that some backend init diagnostics are returned to
624 --- 1.3.34 2012/04/25
626 frontend_log: extend logging (when message is given in config).
628 --- 1.3.33 2012/04/25
630 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
632 --- 1.3.32 2012/04/24
634 sru_z3950 filter passes through incoming Z39.50 requests again. Was
635 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
637 --- 1.3.31 2012/04/24
639 zoom: fixes for retry/proxy failover logic. More logging.
641 --- 1.3.30 2012/04/23
643 zoom: return addinfo="proxy failure" for proxy failures. This also
644 changes the scheme for dealing with proxies a bit. zoom now always
645 do proxy check, even if there's no failover. Fortunately, that's not
648 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
649 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
650 generic. We don't know why the init would fail; IP, user, block IP, etc.
651 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
653 zoom: guess if invalid SRU response was an auth failure
655 session_shared: disable session retry by default . Can be enabled by
656 restart="true" in resultset section.
658 --- 1.3.29 2012/04/18
660 zoom: may read cf-proxy's config settings.
661 This reduces manual configuration of the content proxy server host.
662 The ZOOM module will use the old style session.proxyhost if "server"
663 is given (deprecated) and use the new style proxyhost/session if
664 "config_file" is in use.
666 frontend_net: remove incoming requests that can not be handled
667 Requests in queue for filter frontend_net are removed if client
668 closes connection for the session and request is not yet handled.
670 sru_z3950: serialize requests. This is to ensure that pipelined
671 HTTP requests are handled properly.
673 --- 1.3.28 2012/04/04
675 New class, wrbuf, that wraps YAZ' WRBUF.
677 --- 1.3.27 2012/03/30
679 Metaproxy daemon is now running as user "metaproxy". This user is
680 managed by package maintainer scripts. The user information is stored
681 in /etc/metaproxy/metaproxy.user .
683 --- 1.3.26 2012/03/20
685 New filter, sort, that allows sorting of XML records via Z39.50
688 Filter record_transform: USEMarcon support. For example:
689 <retrieval syntax="usmarc">
690 <backend syntax="unimarc" name="F">
691 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
695 Filter multi: empty route pattern uses route as default.
697 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
698 may use the shorter notation
699 <target route="z3950.indexdata.com"/>
701 Filter query_rewrite: use config path to locate XSLT.
703 Filter frontend_net: log statistics.
704 If a custom message element in frontend_net configuration it makes
705 the frontend_net filter produce a log entry whenever an operation
706 is completed. The log is always written using yaz_log with the
707 custom message given, the package ID (session ID) , the time
708 the operation has been active (end-to-end) , the threads currently
709 active/total and the size of the request input/output queues.
711 query_rewrite: charset conversion of query terms.
712 This is an optional feature. Enabled by element <charset> in
713 configuration with attribute 'from' and 'to' that specifies
714 from/to encodings. The default 'from' encoding is UTF-8.
716 Filter record_transform: honor piggyback searches.
718 Filter zoom: re-connect when database is reused.
719 Re-connect is necessary if a connection is lost or a timeout occurs.
720 If not, we'll be seeing zero hits, when we shouldn't.
722 --- 1.3.25 2012/02/29
724 zoom: Change scheme for dealing with content proxy URLs. The module
725 now has its own common XSL transform that is enabled by record_xsl
726 attribute in the configuration. This XSL gets parameter cproxyhost
727 that holds the host for the content proxy session . The genearted-url
728 is created only if urlRecipe is enabled. In previous version default
729 value of urlRecipe was ${md-electronic-url}; it is now empty and
730 disabled by default. Also generated-url no longer includes the content
731 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
734 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
735 connections. Default value is 40 (seconds).
737 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
738 "Malformed query" for syntax errors and related ones; throw
739 Bib-1: 3 "Unsupported search" for everything else. Details from
740 the CCL parser is provided as additional-info.
742 multi: new setting hideerrors that makes multi only relay diagnostics
743 to a client if all backends fail.
745 --- 1.3.24 2012/02/23
747 zoom: empty ccl_map field-mappings disables CCL map.
749 zoom: fix Explain search that could return error if session was
752 --- 1.3.23 2012/02/10
754 zoom: returns Explain records for database IR-Explain---1. The
755 target profile records are converted to Explain records via XSLT.
757 session_shared: make error recovery configurable. Whether a search
758 is restarted on errors or not, is configurable by attribute "restart"
759 in element "resultset" in configuration.
761 session_shared: only relay init for first request. session_shared, for
762 each backend class, now only relays first init request (rather than all).
763 The module only needs to save init response info once. This avoids the
764 need to check for session max.
766 --- 1.3.22 2012/02/02
768 zoom: fix memory leaks.
770 session_shared: maximum number of sessons is configurable. Default
771 value is 100. Result-sets for backends without named result sets are
772 only re-used if databases is identical for a search. This is under the
773 assumption that performance may suffer for those backends when
774 changing the database for each search.
776 multi: combines diagnostics from all backends. All diagnostics from
777 backends are combined into multiple non-surrogate diagnostics; rather
778 than just one diagnostic from first backend.
780 --- 1.3.21 2011/12/27
782 zoom: relay realm to cproxy parameter file.
784 Configuration: Allow filter collection element inside route. This
785 makes it possible to include multiple filters at once.
787 zoom: nocproxy also disables urlRecipe.
789 --- 1.3.20 2011/12/21
791 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
792 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
793 90: "Unsupported direction value".
795 zoom: honor database argument nocproxy. This disables creating a content
796 connector session (for non-CF targets, usually) and also relays nocproxy
797 as database argument to a CF target.
799 --- 1.3.19 2011/12/16
801 zoom: Multiple proxy hosts may be given for proxy rich database
802 parameter. List is comma separated.
804 http_file: decodes URI paths properly. Does not return 404: not found
805 if no prefix are matches. Instead packages are passed on.
807 --- 1.3.18 2011/12/08
809 zoom: content-{user,password,proxy} are passed on to content proxy
810 system and takes precedence over user,password,proxy .
812 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
813 with a log element including log material from children filters. At
814 this point, only the zoom filter uses this log facility. It will
815 eventually be used by other filters as well. In particular it might be
816 useful for this feature to track all filters in used during a search.
818 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
819 and queries as they are manipulated are logged.
821 zoom: extend addinfo with native diagnostics. Diagnostics as received
822 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
823 diagnostics. This indicates both a backend diagnostic and the original
826 zoom: default urlRecipe value is ${md-electronic-url}
828 zoom: target profile setting sruVersion is recognized.
830 --- 1.3.17 2011/11/17
832 zoom: log target profile record fetched (AKA Torus).
834 --- 1.3.16 2011/11/17
836 Change target profile parameter CfSubDb to CfSubDB.
838 --- 1.3.15 2011/11/12
840 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
841 makes sense to the zoom module itself).
843 --- 1.3.14 2011/11/11
845 zoom: realm may be given as part of database.
847 --- 1.3.13 2011/10/26
849 Fix Origin class assigment method; was removd by mistake in 1.3.12.
851 --- 1.3.12 2011/10/26
853 zoom: database args x-name=value are passed through to backend database.
855 SRU filter: user may specify session ID that is passed to log entries
856 that follows. It is specified by using x-session-id in the SRU arguments.
858 zoom: fix null pointer reference which would occur for bad url parameter
859 inside "torus" or if url was not given.
861 --- 1.3.11 2011/09/09
862 Fix bug in filter session_shared where sessions would not expire
863 properly (session ttl). This in turn could make the target close the
864 connection before expected and session_shared would return diagnostic
865 2: system temporarily available.
867 --- 1.3.10 2011/09/09
869 zoom: new target profile setting: sortmap_field. If sortmap_field is given
870 the field is mapped to the value for the sortmap. Values not matching
871 sortmap_field are passed verbatim.
873 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
874 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
875 depending on whether RPN or CQL is actually sent to the target.
879 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
881 zoom: For content proxy authentication is stored in param name
882 "auth", instead of "authentication".
886 zoom: relay schema in SRU mode. Previously recordSchema was not affected
891 zoom: new target profile element literalTransform that holds XSLT
892 (encoded as string) for target. Only if present and non-zero length it is
893 considered present. This takes precedence over transform.
895 Don't rely on trang anymore for Git checkout builds. Configuration in etc
896 will only be properly validated if trang is available. From now on only
897 relax NC files are bundled with the source dist.
899 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
900 component was not detected when it should be.
904 z3950_client: mark non-surrogate diagnostics from backend.
906 zoom: a proxy may be specified for HTTP fetch of target profiles.
910 Honor piggyback. Makes some SRU targets behave that insist on
911 maximumRecords > 0, but also increases performance.
915 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
916 file was not update for libdir/metaproxy4 in version 1.3.2.
920 Change location of Metaproxy modules from libdir/metaproxy to
921 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
922 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
924 New facility to dump APDUs from zoom filter. Enabled by
925 <log apdu="true"/> in the zoom filter configuation.
927 zoom filter bug fix: SRU diagnostics received from backend was
928 not properly converted to Bib-1 diagnostics.
930 Package metaproxy depends on libmetaproxy4, same version.
934 zoom: fix a bug WRT passing authentication parameters to backends.
938 Fixes for windows Makefile.
940 --- 1.2.10 2011/07/25
942 Change major version of metaproxy library from 3 to 4. This in turn
943 makes new package names for Debian and RPM.
947 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
950 zoom: configurable element sets for record transforms.
952 zoom: the target profile based transform is specified by element_transform
953 in element torus of of the ZOOM filter configuration ; default value
954 is "pz2". Target profile based retrieval is specified by element_raw
955 in configuration. It will perform same steps, but omit the XSL transform.
956 Default value is "raw".
958 zoom: element set is omitted if not set in profile. But only if pz2
959 transform is in effect. Previously the default element set was to "F".
961 zoom: For non-CF targets database arguments are parsed. User may supply
962 db,user=myuser&password=mypass for non-CF targets. These values override
963 what's given the authentication from the target profile.
965 session_shared: fix reference to freed memory. Would occur if a search
966 response had non-surrogate diagnostics.
970 Route may be given for each port in frontend_net.
974 Documentation for zoom filter. Local target profiles may be specified.
976 Fixes for zoom filter.
980 First version with zoom filter.
984 Filter z3950_client may be configured to always send a close APDU
985 to backend target when connection/session is closed. This will only
986 happen if close APDU is not already sent. Enabled by configuration
987 for z3950_client (force_close).
989 Filter virt_db and multi: relay close APDU.
991 Filter virt_db and multi: relay init size parameters
992 preferredMessageSize and maximumRecordSize.
994 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
998 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
1000 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
1001 as determined by configure.
1003 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1004 this package can be distinguished from other vendors.
1006 --- 1.2.3 2010/10/04
1008 Fix filter multi: relay idAuthentication parameters.
1010 --- 1.2.2 2010/09/15
1012 Add metaproxy-config for returning compiler flags, libraries.
1014 --- 1.2.1 2010/08/18
1016 Fix --with-boost=PREFIX .
1018 --- 1.2.0 2010/07/09
1020 session_shared: fix use of maintenance thread.
1022 Introduce 'start' method for filters and routers. It gets called after
1023 configure and after fork, but before processing. This changes API -
1024 from libmetaproxy2 to libmetaproxy3.
1026 --- 1.1.7 2010/06/30
1028 session_shared: ensure backend session is closed if init rejected
1031 z3950_client: fix NULL ptr reference that could occur if two clients
1032 connected concurrently and if max-sockets was in effect.
1034 --- 1.1.6 2010/06/21
1036 Fix bug 3497 - Metaproxy unstable while stopping.
1038 Fix bug 3495 - SEGV in SRU filter.
1040 --- 1.1.5 2010/06/15
1042 Filter multi throws diagnostic 'Present Out of Range' when
1043 appropriate - rather than returning 0 records.
1045 Filter virt_db: fix bad result reuse. Could happen if a result
1046 was overriden and a backend did not supported named result sets.
1048 --- 1.1.4 2010/05/11
1050 Filter log: category access logs diagnostics even if searchStatus
1051 or presentStatus is 'success'.
1053 --- 1.1.3 2010/04/21
1055 The SRU to Z39.50 filter does repeated Z39.50 present requests
1056 to fetch all records. Needed when a Z39.50 server returns partial
1057 results (due to message size limits).
1059 --- 1.1.2 2010/03/18
1061 Metaproxy now kills all child processes that are spawned by
1062 modules (in case of fork, exec).
1064 --- 1.1.1 2010/01/28
1066 Debian package now installs /etc/metaproxy/metaproxy.xml which
1067 includes all XML files /etc/metaproxy/filters-enabled .
1068 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1070 --- 1.1.0 2010/01/20
1072 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1073 development package to facilitate 3rd party Metaproxy modules.
1075 --- 1.0.23 2010/01/04
1077 Filter virt_db: Close backend filter session when Init rejected is received
1078 from it (in which case it's not really closed yet). This will ensure we don't
1079 run out of resources such as FDs in this case.
1081 sru_z3950 filter: Accept any database (including those not listed).
1083 --- 1.0.22 2009/12/03
1085 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1086 later which means YAZ 3.0.47 or later.
1088 --- 1.0.20 2009/11/19
1090 For filter virt_db, the database is a glob pattern and the virtual
1091 database sections are consulted in the order given.
1093 --- 1.0.19 2009/07/08
1095 For filter multi, the target (for routing) may be given as a glob-pattern.
1097 More documentation for filters virt_db and multi.
1099 Update schema to allow for no database in sru_z3950 filter.
1101 --- 1.0.18 2009/06/30
1103 Added limit filter to put sleep (penalty) for heavy use.
1105 Filter frontend_net may be configured to limit the number of new connections
1106 from same IP to some value (connect-max).
1108 Fixed the load_balance filter.
1110 --- 1.0.17 2009/06/16
1112 Fix path for metaproxy executable for Debian init.d script.
1114 --- 1.0.16 2009/06/10
1116 SRU to Z39.50 filter honors x-username and x-password. If only
1117 x-username is given that translates to open authentication (Z39.50v2). If
1118 both x-username and x-password is present that translates to idPass
1119 authentication (Z39.50v3).
1121 New facility to change current working directory (-w).
1123 Update to upstream skeleton of init.d script. Should fix bug #2619.
1125 Filter session_shared now caches records (used to only cache connections
1128 Filter session_shared now invalidates a Z39.50 session if a server
1129 returns -1 hits. This facility was also part of yazproxy and gets around
1130 a bug in Voyager-based Z39.50 servers.
1132 --- 1.0.15 2008/11/18
1134 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1136 --- 1.0.14 2008/06/09
1138 Fixed the value of SRU record schema in searchRetrieve response. It was set
1139 to a fixed value of "dc" before.
1141 Serialize identical SRU requests. This is useful if HTTP client software
1142 fires identical requests against metaproxy.
1144 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1145 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1146 avoid static configuration. This facility is handled by the sru_z3950 module
1147 and the z3950_client module.
1149 Allow maximum number of sockets to be used for a Z39.50 client by the
1150 use of SRU extra parameter x-max-sockets. This facility is handled by the
1151 sru_z3950 module and the z3950_client module.
1153 --- 1.0.13.1 2008/02/29
1155 Simplified check for Boost libraries.
1157 --- 1.0.13 2008/02/29
1159 First Debian package.
1161 The sru_z9350 filter now recognizes SRU parameter z-target as being
1162 a ZURL of the form host/database .
1164 Mergetype may be specified for filter 'multi'.
1166 --- 1.0.12 2007/09/19
1168 Fixed problem in Makefile WRT library specifictions. This could produce
1169 linker errors (when they should not happen).
1171 Fixed bug #1341: MetaProxy returning different results. Problem was that
1172 fix-up of record database did not normalize the database name.
1174 Documentation updates for Windows compilation.
1176 --- 1.0.11 2007/06/14
1178 Fixed problem with logfile being truncated.
1180 --- 1.0.10 2007/05/23
1182 Fixed bug #1136: Access rights not enforced.
1184 Extension for log module. The log category 'access' logs more details.
1185 New category 'user-access' added which is simlar to 'access' but adds
1186 the Z39.50 user as for all entries in a session.
1190 Added support for configurable default/force target/vhost for module Z39.50
1193 --- 1.0.8 2007/01/25
1195 Implemented filter, session_shared, which optimizes usage of Z39.50
1196 sessions and result sets.
1198 New filter, record_transform, which converts MARC/XML records.
1200 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1202 New filter, load_balance, in development.
1204 New filter, zeerex_xplain.
1206 XML framework for config files started.
1208 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1209 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1210 XML config files are checked against RNG and XML Schema's.
1212 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1213 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1214 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1215 explain record to YAZ CQL-to-PQF text config file.
1217 --- 1.0.7 2006/11/07
1219 Added 'timeout' setting for filter frontend_net which specifies the number
1220 of seconds a session is idle before it is closed. Default timeout is
1223 --- 1.0.6 2006/07/07
1225 Database name in records returned set for virt_db/multi filters.
1227 Filter session_shared now functional.
1229 Log filter can be configured to write to a given file using 'filename'
1230 element. Also information category can be specified with 'category'. If
1231 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1234 --- 1.0.5 2006/05/16
1236 Fixed compilation on Windows.
1238 --- 1.0.4 2006/05/16
1240 Added documentation for the hidenavailable option for the multi filter.
1242 --- 1.0.3 2006/05/16
1244 Fixed bug #573: Hide errors for individual servers. If the element
1245 'hideunavailable' is given in the configuration, individual servers
1246 being unavailable are hidden (unless all are unavailable).
1248 Fixed bug #574: Database names are recognised case-sensitively.
1250 Fixed bug #567: Fix up database name in Name-Plus-Record.
1252 Fixed bug #568: Update win/makefile for VS 2005.
1254 Fixed bug #569: Some options throws unknown exception.
1256 --- 1.0.2 2006/04/28
1258 More information about virtual hosts. The 'etc' directory is part of the
1261 --- 1.0.1 2006/04/27
1263 Build instructions for Windows. NMake makefile part of distribution tar.
1265 --- 1.0.0 2006/04/24
1269 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1270 log, multi, query_rewrite, template, virt_db, z3950_client.
1272 Filters in development: session_shared.
1274 Pseudo-filters: template, dl
