3 Fix double free in log filter (with incorrect config) MP-589
5 zoom: Add allow_ip feature - fixes MP-588
6 Allow a list of IPs to be given separated by blanks
7 <allow auth_url="http://mkc-admin.indexdata.com/..."
8 allow_ip="127.0.0.1 ::1" .. >
10 cql2pqf.txt: Maps dc.subject to Bib-1 21 rather than 47
12 zoom: fix CS write-check
16 zoom: handle contentAuthentication MP-587
20 Destroy router and filters in parent process MP-584
22 Update NMAKE makefile to use Visual Studio 2013 along with Boost 1.57,
23 ICU 54.1, Libxml2 2.9.2, Libxslt 1.1.28.
27 Use YAZ backtrace facility MP-582
29 Fix libmetaproxy-dev depends on libgnutls-dev - MP-580
30 libgnutls-dev is unavailable on jessie.
32 Update template filter to avoid Pimpl MP-579
34 cgi: POSTed content - part of MP-562
36 Fix filter cgi does not relay session close MP-577
40 Add support for binding outgoing IP for http_client and z3950_client
41 This is enabled by bind_host setting. MP-575
45 z3950_client: allows negotiation charset to be set MP-574
47 cgi: more functional but no support for POSTed content yet (part of MP-564)
51 http_file: add include of sys/stat.h fixes MP-576
53 Fix documentation about SRU client support MP-572
55 Initialize Libxml2 - for threaded operation MP-571
59 On SIGTERM shut down connection+listening sockets MP-568
60 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
64 zoom: make retry on failure configurable MP-565
65 The default and existing behavior is that backend failures (any
66 diagnostic) makes the module re-search once. The behavior may
67 be changed by db parameter 'retry'. If given value '0' disables
68 retry and '1' enables it. If not given, the Torus record may
69 specify with element retryOnFailure (value '0'/'1').
73 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
74 instead of just a child process. Extremely rare in real life, hit me with
75 CF stress testing. MP-559.
79 http_file: passthru option MP-557
80 New facility for http_file to passthru - even if an area is matched. The
81 default behavior (passthru=false) is to return 404: Not found. With
82 passthru=false, next filter is consulted.
86 Fix ref to freed memory in log filter 1line - MP-556
88 echoedSearchRetrieveRequest support MP-555
92 zoom: allow hostname to be given for ipauth MP-552
93 The Torus setting for that is called auth_hostname.
97 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
101 session_shared: close in ~BackendInstance MP-549
102 This fixes a serious issue where some MP would leak sockets.
104 session_shared: mutex lock in BackendClass::release_backend MP-550
105 Fixes a SEGV that could occur (in rare cases).
109 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
111 zoom: fix invalid present response in some cases MP-546
113 zoom: Relay Torus HTTP error message
117 Check for proper limits before using RecordCache functions MP-544
121 Build packages for Ubuntu Trusty Tahr 14.04 LTS
123 sort: crash / invalid_read in filter sort MP-541
125 sru_z3950: facet should be stored in additionalSearchInfo MP-533
127 doc: fix missing man pages MP-542
129 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
131 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
135 sru_z3950: fix facet response (memory corruption) MP-532
137 log: fix crash idPass user is omitted MP-530
141 query_rewrite: pass-thru non Type-1 queries MP-527
143 metaproxy stop (SIGTERM) kills all child processes spanwed by
144 filter (if any) before invoking filter destructors. MP-525
148 http_file: only supports HTTP GET MP-523
150 session_shared: shut down expire thread in destructor
151 This ensures that expire thread is not running after destruction
152 and does bad memory references, etc.
154 frontend_net: fix segfault on startup MP-524
155 Would happen if MP was listening on multiple ports and one
156 of the ports was already in use (and MP would exit).
158 frontend_net: fix memory leak MP-521
159 This leak would occur if all sessions were in use and the input
160 queue was cleared when a client would close connection (socket).
162 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
166 http_rewrite: use local skiplist; fixes memory corruption. MP-520
168 http_client: x-forwarded-for controls X-Forwarded-For presence
169 If x-forwarded-for setting (boolean) is enabled, http_client will
170 generate an X-Forwarded-For header entry which includes existing
171 X-Forwarded-For (if any) and current peer address (immediate client
172 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
173 will not be generated.
175 z3950_client: client_ip controls client-IP presence
176 If client_ip setting (boolean) is enabled, z3950_client will
177 generate a client_ip OID as part of init request which includes
178 previous client_ip (if any) and current peer address (immediate
179 client of Metaproxy). By default client_ip is disabled and client_ip
180 will not be generated.
182 HTTP X-Forwarded-For/Z39.50 Client-IP support
183 virt_db, multi: relays Z39.50 client-IP.
184 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
185 zoom: uses Client-IP or origin address (prefer Client-IP).
186 frontend_net: Strips tcp: from peer address (so that it is no longer
187 printed and stripped in zoom filter).
188 z3950_client: builds client-IP list - combining immediate peer address
189 as returned by COMSTACK and existing client-IP list (if avaiable).
190 The Origin only printes first X-Forwarded address.
194 Log when SIG{TERM,USR1} is received ASAP MP-513
195 Do it in frontend_net event loop rather than in place for metaproxy
196 main, which only exits when all sessions are terminated for SIGUSR1
199 metaproxy-config: quote some RHS values (that might include blanks)
201 Fix leak in sru_z3950 filter - when explain is returned MP-511
203 Allow stylesheet to be given for sru_z3950 filter MP-510
204 This is based on a patch by Sven Porst and the functionality
205 of the YAZ Generic Frontend Server.
207 Allow base attribute in configuration file tags - the attributes are
208 inserted by XInclude usage as mentioned on
209 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
210 and noted in a gist: https://gist.github.com/3551094
212 Package metaproxy provides virtual package metaproxy6 MP-508
213 This allows module packages to depend on a metaproxy server
216 Filter destructors called upon daemon termination MP-505
217 When metaproxy daemon receives SIGTERM the stop method of each filter
218 is called. The stop method existed before, but did not take any
219 arguements (void).. The frontend_net filter can now distinguish
220 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
221 (stop immediately). Note that this changes the API+ABI of Metaproxy
224 zoom: sync up with Pazpar2 WRT authentication handling MP-492
226 Router: use shared_ptr rather than naked one - to avoid leak if an
227 exception is thrown in configure.
231 zoom: Add nocproxy=1 for contentConnector sessions MP-501
233 Doc: mention proper versions; fix link to Boost win binaries.
235 Windows: update for Boost 1.55
237 Windows: avoid warning when using boost::split. Done by defining
238 _SCL_SECURE_NO_WARNINGS for Visual Studio.
240 Fix LSB conformance for /etc/init.d/metaproxy MP-500
241 Debian: add support for /etc/init.d/metaproxy status
243 sort: Add const to Record less than operator in order to compile on
248 session_shared: fix element-set handling in record caching. MP-499
250 document http_rewrite. MP-468
252 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
253 respects the header (which will normally come from the cproxy filter)
257 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
258 RPM was unsable in version 1.4.0.
260 Remove log message about "backend classes". Appeared in version 1.4.0.
264 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
265 with older version from source, but packages now use YAZ 5 that supports
268 sru_z3950: Fix SEGV for decoding invalid SRU requests
269 Incorrect reference to union (was explain response rather than
272 session_shared: match additionalSearchInfo (includes facets). In
273 layman's terms means that means that facets are properly handled
274 by this filter. Eg a change in requested facets will issue new
275 search and facets from exisiting result set are cached.
277 --- 1.3.62 2013/09/11
279 http_rewrite: better handling of <script> content in HTML parser. MP-486
281 http_rewrite: fix threading issue with regex. MP-482
283 bounce: don't use strdup for fixed length content. Error occurred in echo
286 session_shared: expire backend class when no instances left. This
287 means memory clean up, but not really a leak fix.
289 virt_db: fix leak for naked ptr.
291 cql_rpn: use config relative path for cql2rpn file. MP-481
293 Updates for upcoming YAZ 5.
295 --- 1.3.61 2013/08/29
297 New configuration directories ports.d/routes.d for metaproxy
298 configuration. This allows 3rd party packages to install config
299 for ports and new routes. MP-477
301 --- 1.3.60 2013/08/21
303 Fix metaproxy-config --libs to return non-mt over mt libs.
304 The -mt versions do not exist as shared objects and cause
305 linker errors for applications linking with Metaproxy.
306 Problem present in versions 1.3.56 - 1.3.59. MP-475
308 HTML: clean up char checks. Add ptr to HTML parse spec
310 HTML parser stops eating tag when <-char is met MP-473
312 rewrite: do not even compare content types, if we don't have any
313 the regex_match caused a segfault if we had no content-type in the
316 rewrite: within header=... matches only the header value
317 Used to match the whole header line, but we need to use
318 ^$ anchoring for host-relative regexps, and they need to
319 anchor at the ends of the value. MP-470.
321 rewrite: Ruleset functional MP-469
323 --- 1.3.59 2013/07/12
325 session_shared: negotiate init sz parameters.
326 By default, session_shared will honor the paramters given by client.
327 An alternative, but not implemented, algorithm would be to only
328 re-use sessions with same sz parameters. This however, could reduce
329 re-use of sessions a lot. Hence this, simple algorithm instead. The
330 negotiation to a maximum sz values can be enabled by using
331 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
332 in configuration. This will make session_shared send those values
333 to backends and use returned init values in negotaition to
334 client before session_shared.
336 session_shared: resolve result-set references.
337 The reference is substitued with the query for old set if database
338 match and query type is Type-1. If not the reference will issue a
341 sort filter: relays RecordComposition including elementSet in use for
344 http_client: better diagnostics
346 http_client: disables HTTP redirect handling by default.
347 It can be configured with max-redirects in configuration.
349 --- 1.3.58 2013/06/12
351 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
353 --- 1.3.57 2013/06/12
355 Make RouterChain and RouterXML part of public API (libmetaproxy).
357 http_client: honor X-Metaproxy-Proxy as an alternative to
358 the "proxy" configuration. Allows proxy to be set per HTTP request.
360 sru_z3950: For SRU requests recognize x-client prefixes as a way
361 to ingest "database parameters".. The suffix of x-client- serves
362 as database argument name. Multiple may be given. For example:
363 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
364 is turned into Z39.50 database
367 --- 1.3.56 2013/05/27
369 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
371 New filter sd_remove, which replaces surrogate diagnostics with
372 SUTRS records. This filter tries to deal with clients that breaks
373 when receiving surrogate diagnostics.
375 new filter http_client. Same role as z3950_client, but just for
376 HTTP. Allows Metaproxy to operate as a HTTP proxy.
378 New filter http_rewrite1, which serves as purpose on how to rewrite
379 HTTP content with Metaproxy.
381 Use libboost-system if available, because newer versions of libboost-threads
382 requires libboost-system.
384 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
387 --- 1.3.55 2013/04/10
389 zoom: Torus setting: authenticationMode which may hold values "basic"
392 --- 1.3.54 2013/03/27
394 configure: check for Libxslt support in YAZ and rely on definitions
395 from yaz-config, rather than doing own xslt/xml2 checks.
397 Allow timestamp format for log lines to be given with option -m
398 for metaproxy. Similar to yaz-ztest/GFS option -m.
400 Document log category 'line' for log filter.
402 Solr configuration example in etc/config-solr.xml
404 multi: do not mess with request package. For scan and search,
405 database-names were modified and the request package was left with
406 dangling pointers that caused a log filter to fail (request package
407 inspected after multi was invoked).
409 Documentation: fix id of metaproxy-config ref .
411 Documentation: update for USEMARCON support.
413 --- 1.3.53 2013/01/31
415 record_transform: allow OPACXML to OPAC conversion
417 zoom: document content-proxy
419 zoom: document db parm content-{user,password}, torus_url. Also
420 <torus auth_url="..> which makes zoom operate in authenticated mode
423 --- 1.3.52 2012/11/30
425 zoom: fix http://-check. SRU search broken in 1.3.51.
427 --- 1.3.51 2012/11/15
429 zoom: only append http:// for SRU if not already given . Makes it
430 possible to use https-URLs.
432 Use yazpp 1.4 or later due to new ABI.
434 frontend_net: allow max package size to be specified. Controlled by
435 attribute 'max_recv_bytes' of element 'port'.
437 --- 1.3.50 2012/10/29
439 For most generated diagnostics by filters, typically temporary
440 system error, augment addinfo message with filter name.
442 Add support for CentOS 6 packages.
444 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
446 Add man page for metaproxy-config.
448 --- 1.3.49 2012/10/18
450 zoom: new config element passthru. This defines an element set that is
451 passed verbatim to the backend in pz2 mode.
453 auth_simple: allow both idPass and open auth. Also fix SEGV that could
456 --- 1.3.48 2012/10/08
458 z3950_client: fix string handling for init diagnostics in the case where
461 query_rewrite: no charset conversion for error queries. Avoid performing
462 charset conversion for query conversion errors. The resulting Type-1
463 query is invalid in this case.
465 --- 1.3.47 2012/10/04
467 For graceful stop (SIGUSR1), metaproxy will kill children processes.
469 Log when metaproxy is invoked in test mode (-t).
471 Log PID for each log message.
473 multi: combine both NSDs and multiple NSDs into one (diagnostics).
475 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
476 a (backend=target) is appended for each diagnostic so that can be
477 determined the origin of error.
479 multi: hideerrors also in use for present response.
481 Solr example in zoom man page.
483 Fix typo in query_rewrite config example.
485 Log at least first non surrogate diagnostic. Instead of
486 "Z_Records_multipleNSD"
488 multi: Fix check for opt Records in present response. A SEGV could occur
489 if a target did not return records and no diagnostics.
491 --- 1.3.46 2012/09/24
493 Yet another fix for graceful stop.
495 --- 1.3.45 2012/09/12
497 sru_z3950: relay surrogate diagnostics.
499 --- 1.3.44 2012/09/10
501 zoom: Honor extraArgs, strip # in zurl.
503 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
505 zoom: url_recipe allow %{var[reg]} substitutions.
506 It's like ${var[reg]} but does URI component encoding as well.
508 --- 1.3.43 2012/08/22
510 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
511 non-keepalive HTTP sessions.
513 http_file: allow zero size files (bug fix)
515 Fix zoom schema: auth_url is optional
517 --- 1.3.42 2012/08/20
519 zoom: fix un-init memory (could result in SEGV at session close)
521 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
522 and may be used in filters as usual.
524 zoom: authentication via Torus lookup
525 Enabled by new configuration setting: auth_url . If this is defined,
526 the zoom module will contact Torus for auth/IP lookup and that will
527 define realm to be used in session.
529 --- 1.3.41 2012/08/10
531 virt_db: Fix database name - first character we removed by mistake.
532 Bug introduced in 1.3.40.
534 --- 1.3.40 2012/08/06
536 virt_db: Don't use "unix path" as database for Unix sockets.
538 --- 1.3.39 2012/08/02
540 z3950_client: Don't tamper with / in zurl - fixes problems
541 using Unix sockets for backends.
543 session_shared: fix integer overflow problem with hit count.
545 session_shared: avoid long usage of cached queries.
547 zoom: New database argument , torus_url to set URL of Torus
548 record to be fetched.
550 --- 1.3.38 2012/07/04
552 Fixes for 'metaproxy reload' for RPM/Debian packages.
554 zoom: Allow rpn2cql conversion to be augmented with a properties file.
555 Element rpn2cql can be specified per-target for the zoom filter.
557 log: New category "line" which is a single-line log message with
558 most important parts of a HTTP/Z39.50 request/response.
560 --- 1.3.37 2012/06/01
562 frontend_net: add facility to report live statistics about response
563 times and current thread usage. The report is an XML document
564 and is triggered for a specific URL path. This is set by <stat-req>
565 in the configuration of frontend_net. By default this report is
566 disabled (same as empty value for <stat-req>).
568 Fix reload problem in init.d script for RPM/Debian.
569 The '/etc/init.d/metaproxy reload' in some cases would stop but not
570 start metaproxy - effectively stopping the service.
572 Don't display start log message when config testing (-t).
574 zoom: avoid CCL message limit of 1K in ZOOM filter.
576 --- 1.3.36 2012/05/10
578 metaproxy init script reacts to reload which does graceful stop +
579 start and is used by logrorate script.
581 --- 1.3.35 2012/05/09
583 Fixes for Windows compilation.
585 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
586 existing sessions running but terminate the monitor process that is
587 used in keepalive mode.
589 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
590 before. Consistent with 'metaproxy stop' message.
592 zoom: document zoom's proxy_timeout
594 z3950_client: fixup addinfo for init response
596 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
597 "Access to specified database denied" is returned, but only if init
598 response from backend does not carry diagnostics already.
600 multi: relays user info for first rejected target. The other-information
601 field for init response for first rejected target is in common init
602 response. This ensures that some backend init diagnostics are returned to
605 --- 1.3.34 2012/04/25
607 frontend_log: extend logging (when message is given in config).
609 --- 1.3.33 2012/04/25
611 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
613 --- 1.3.32 2012/04/24
615 sru_z3950 filter passes through incoming Z39.50 requests again. Was
616 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
618 --- 1.3.31 2012/04/24
620 zoom: fixes for retry/proxy failover logic. More logging.
622 --- 1.3.30 2012/04/23
624 zoom: return addinfo="proxy failure" for proxy failures. This also
625 changes the scheme for dealing with proxies a bit. zoom now always
626 do proxy check, even if there's no failover. Fortunately, that's not
629 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
630 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
631 generic. We don't know why the init would fail; IP, user, block IP, etc.
632 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
634 zoom: guess if invalid SRU response was an auth failure
636 session_shared: disable session retry by default . Can be enabled by
637 restart="true" in resultset section.
639 --- 1.3.29 2012/04/18
641 zoom: may read cf-proxy's config settings.
642 This reduces manual configuration of the content proxy server host.
643 The ZOOM module will use the old style session.proxyhost if "server"
644 is given (deprecated) and use the new style proxyhost/session if
645 "config_file" is in use.
647 frontend_net: remove incoming requests that can not be handled
648 Requests in queue for filter frontend_net are removed if client
649 closes connection for the session and request is not yet handled.
651 sru_z3950: serialize requests. This is to ensure that pipelined
652 HTTP requests are handled properly.
654 --- 1.3.28 2012/04/04
656 New class, wrbuf, that wraps YAZ' WRBUF.
658 --- 1.3.27 2012/03/30
660 Metaproxy daemon is now running as user "metaproxy". This user is
661 managed by package maintainer scripts. The user information is stored
662 in /etc/metaproxy/metaproxy.user .
664 --- 1.3.26 2012/03/20
666 New filter, sort, that allows sorting of XML records via Z39.50
669 Filter record_transform: USEMarcon support. For example:
670 <retrieval syntax="usmarc">
671 <backend syntax="unimarc" name="F">
672 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
676 Filter multi: empty route pattern uses route as default.
678 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
679 may use the shorter notation
680 <target route="z3950.indexdata.com"/>
682 Filter query_rewrite: use config path to locate XSLT.
684 Filter frontend_net: log statistics.
685 If a custom message element in frontend_net configuration it makes
686 the frontend_net filter produce a log entry whenever an operation
687 is completed. The log is always written using yaz_log with the
688 custom message given, the package ID (session ID) , the time
689 the operation has been active (end-to-end) , the threads currently
690 active/total and the size of the request input/output queues.
692 query_rewrite: charset conversion of query terms.
693 This is an optional feature. Enabled by element <charset> in
694 configuration with attribute 'from' and 'to' that specifies
695 from/to encodings. The default 'from' encoding is UTF-8.
697 Filter record_transform: honor piggyback searches.
699 Filter zoom: re-connect when database is reused.
700 Re-connect is necessary if a connection is lost or a timeout occurs.
701 If not, we'll be seeing zero hits, when we shouldn't.
703 --- 1.3.25 2012/02/29
705 zoom: Change scheme for dealing with content proxy URLs. The module
706 now has its own common XSL transform that is enabled by record_xsl
707 attribute in the configuration. This XSL gets parameter cproxyhost
708 that holds the host for the content proxy session . The genearted-url
709 is created only if urlRecipe is enabled. In previous version default
710 value of urlRecipe was ${md-electronic-url}; it is now empty and
711 disabled by default. Also generated-url no longer includes the content
712 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
715 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
716 connections. Default value is 40 (seconds).
718 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
719 "Malformed query" for syntax errors and related ones; throw
720 Bib-1: 3 "Unsupported search" for everything else. Details from
721 the CCL parser is provided as additional-info.
723 multi: new setting hideerrors that makes multi only relay diagnostics
724 to a client if all backends fail.
726 --- 1.3.24 2012/02/23
728 zoom: empty ccl_map field-mappings disables CCL map.
730 zoom: fix Explain search that could return error if session was
733 --- 1.3.23 2012/02/10
735 zoom: returns Explain records for database IR-Explain---1. The
736 target profile records are converted to Explain records via XSLT.
738 session_shared: make error recovery configurable. Whether a search
739 is restarted on errors or not, is configurable by attribute "restart"
740 in element "resultset" in configuration.
742 session_shared: only relay init for first request. session_shared, for
743 each backend class, now only relays first init request (rather than all).
744 The module only needs to save init response info once. This avoids the
745 need to check for session max.
747 --- 1.3.22 2012/02/02
749 zoom: fix memory leaks.
751 session_shared: maximum number of sessons is configurable. Default
752 value is 100. Result-sets for backends without named result sets are
753 only re-used if databases is identical for a search. This is under the
754 assumption that performance may suffer for those backends when
755 changing the database for each search.
757 multi: combines diagnostics from all backends. All diagnostics from
758 backends are combined into multiple non-surrogate diagnostics; rather
759 than just one diagnostic from first backend.
761 --- 1.3.21 2011/12/27
763 zoom: relay realm to cproxy parameter file.
765 Configuration: Allow filter collection element inside route. This
766 makes it possible to include multiple filters at once.
768 zoom: nocproxy also disables urlRecipe.
770 --- 1.3.20 2011/12/21
772 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
773 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
774 90: "Unsupported direction value".
776 zoom: honor database argument nocproxy. This disables creating a content
777 connector session (for non-CF targets, usually) and also relays nocproxy
778 as database argument to a CF target.
780 --- 1.3.19 2011/12/16
782 zoom: Multiple proxy hosts may be given for proxy rich database
783 parameter. List is comma separated.
785 http_file: decodes URI paths properly. Does not return 404: not found
786 if no prefix are matches. Instead packages are passed on.
788 --- 1.3.18 2011/12/08
790 zoom: content-{user,password,proxy} are passed on to content proxy
791 system and takes precedence over user,password,proxy .
793 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
794 with a log element including log material from children filters. At
795 this point, only the zoom filter uses this log facility. It will
796 eventually be used by other filters as well. In particular it might be
797 useful for this feature to track all filters in used during a search.
799 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
800 and queries as they are manipulated are logged.
802 zoom: extend addinfo with native diagnostics. Diagnostics as received
803 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
804 diagnostics. This indicates both a backend diagnostic and the original
807 zoom: default urlRecipe value is ${md-electronic-url}
809 zoom: target profile setting sruVersion is recognized.
811 --- 1.3.17 2011/11/17
813 zoom: log target profile record fetched (AKA Torus).
815 --- 1.3.16 2011/11/17
817 Change target profile parameter CfSubDb to CfSubDB.
819 --- 1.3.15 2011/11/12
821 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
822 makes sense to the zoom module itself).
824 --- 1.3.14 2011/11/11
826 zoom: realm may be given as part of database.
828 --- 1.3.13 2011/10/26
830 Fix Origin class assigment method; was removd by mistake in 1.3.12.
832 --- 1.3.12 2011/10/26
834 zoom: database args x-name=value are passed through to backend database.
836 SRU filter: user may specify session ID that is passed to log entries
837 that follows. It is specified by using x-session-id in the SRU arguments.
839 zoom: fix null pointer reference which would occur for bad url parameter
840 inside "torus" or if url was not given.
842 --- 1.3.11 2011/09/09
843 Fix bug in filter session_shared where sessions would not expire
844 properly (session ttl). This in turn could make the target close the
845 connection before expected and session_shared would return diagnostic
846 2: system temporarily available.
848 --- 1.3.10 2011/09/09
850 zoom: new target profile setting: sortmap_field. If sortmap_field is given
851 the field is mapped to the value for the sortmap. Values not matching
852 sortmap_field are passed verbatim.
854 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
855 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
856 depending on whether RPN or CQL is actually sent to the target.
860 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
862 zoom: For content proxy authentication is stored in param name
863 "auth", instead of "authentication".
867 zoom: relay schema in SRU mode. Previously recordSchema was not affected
872 zoom: new target profile element literalTransform that holds XSLT
873 (encoded as string) for target. Only if present and non-zero length it is
874 considered present. This takes precedence over transform.
876 Don't rely on trang anymore for Git checkout builds. Configuration in etc
877 will only be properly validated if trang is available. From now on only
878 relax NC files are bundled with the source dist.
880 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
881 component was not detected when it should be.
885 z3950_client: mark non-surrogate diagnostics from backend.
887 zoom: a proxy may be specified for HTTP fetch of target profiles.
891 Honor piggyback. Makes some SRU targets behave that insist on
892 maximumRecords > 0, but also increases performance.
896 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
897 file was not update for libdir/metaproxy4 in version 1.3.2.
901 Change location of Metaproxy modules from libdir/metaproxy to
902 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
903 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
905 New facility to dump APDUs from zoom filter. Enabled by
906 <log apdu="true"/> in the zoom filter configuation.
908 zoom filter bug fix: SRU diagnostics received from backend was
909 not properly converted to Bib-1 diagnostics.
911 Package metaproxy depends on libmetaproxy4, same version.
915 zoom: fix a bug WRT passing authentication parameters to backends.
919 Fixes for windows Makefile.
921 --- 1.2.10 2011/07/25
923 Change major version of metaproxy library from 3 to 4. This in turn
924 makes new package names for Debian and RPM.
928 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
931 zoom: configurable element sets for record transforms.
933 zoom: the target profile based transform is specified by element_transform
934 in element torus of of the ZOOM filter configuration ; default value
935 is "pz2". Target profile based retrieval is specified by element_raw
936 in configuration. It will perform same steps, but omit the XSL transform.
937 Default value is "raw".
939 zoom: element set is omitted if not set in profile. But only if pz2
940 transform is in effect. Previously the default element set was to "F".
942 zoom: For non-CF targets database arguments are parsed. User may supply
943 db,user=myuser&password=mypass for non-CF targets. These values override
944 what's given the authentication from the target profile.
946 session_shared: fix reference to freed memory. Would occur if a search
947 response had non-surrogate diagnostics.
951 Route may be given for each port in frontend_net.
955 Documentation for zoom filter. Local target profiles may be specified.
957 Fixes for zoom filter.
961 First version with zoom filter.
965 Filter z3950_client may be configured to always send a close APDU
966 to backend target when connection/session is closed. This will only
967 happen if close APDU is not already sent. Enabled by configuration
968 for z3950_client (force_close).
970 Filter virt_db and multi: relay close APDU.
972 Filter virt_db and multi: relay init size parameters
973 preferredMessageSize and maximumRecordSize.
975 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
979 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
981 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
982 as determined by configure.
984 RPM: Release includes 'indexdata' name. Use indexdata in release name so
985 this package can be distinguished from other vendors.
989 Fix filter multi: relay idAuthentication parameters.
993 Add metaproxy-config for returning compiler flags, libraries.
997 Fix --with-boost=PREFIX .
1001 session_shared: fix use of maintenance thread.
1003 Introduce 'start' method for filters and routers. It gets called after
1004 configure and after fork, but before processing. This changes API -
1005 from libmetaproxy2 to libmetaproxy3.
1007 --- 1.1.7 2010/06/30
1009 session_shared: ensure backend session is closed if init rejected
1012 z3950_client: fix NULL ptr reference that could occur if two clients
1013 connected concurrently and if max-sockets was in effect.
1015 --- 1.1.6 2010/06/21
1017 Fix bug 3497 - Metaproxy unstable while stopping.
1019 Fix bug 3495 - SEGV in SRU filter.
1021 --- 1.1.5 2010/06/15
1023 Filter multi throws diagnostic 'Present Out of Range' when
1024 appropriate - rather than returning 0 records.
1026 Filter virt_db: fix bad result reuse. Could happen if a result
1027 was overriden and a backend did not supported named result sets.
1029 --- 1.1.4 2010/05/11
1031 Filter log: category access logs diagnostics even if searchStatus
1032 or presentStatus is 'success'.
1034 --- 1.1.3 2010/04/21
1036 The SRU to Z39.50 filter does repeated Z39.50 present requests
1037 to fetch all records. Needed when a Z39.50 server returns partial
1038 results (due to message size limits).
1040 --- 1.1.2 2010/03/18
1042 Metaproxy now kills all child processes that are spawned by
1043 modules (in case of fork, exec).
1045 --- 1.1.1 2010/01/28
1047 Debian package now installs /etc/metaproxy/metaproxy.xml which
1048 includes all XML files /etc/metaproxy/filters-enabled .
1049 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1051 --- 1.1.0 2010/01/20
1053 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1054 development package to facilitate 3rd party Metaproxy modules.
1056 --- 1.0.23 2010/01/04
1058 Filter virt_db: Close backend filter session when Init rejected is received
1059 from it (in which case it's not really closed yet). This will ensure we don't
1060 run out of resources such as FDs in this case.
1062 sru_z3950 filter: Accept any database (including those not listed).
1064 --- 1.0.22 2009/12/03
1066 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1067 later which means YAZ 3.0.47 or later.
1069 --- 1.0.20 2009/11/19
1071 For filter virt_db, the database is a glob pattern and the virtual
1072 database sections are consulted in the order given.
1074 --- 1.0.19 2009/07/08
1076 For filter multi, the target (for routing) may be given as a glob-pattern.
1078 More documentation for filters virt_db and multi.
1080 Update schema to allow for no database in sru_z3950 filter.
1082 --- 1.0.18 2009/06/30
1084 Added limit filter to put sleep (penalty) for heavy use.
1086 Filter frontend_net may be configured to limit the number of new connections
1087 from same IP to some value (connect-max).
1089 Fixed the load_balance filter.
1091 --- 1.0.17 2009/06/16
1093 Fix path for metaproxy executable for Debian init.d script.
1095 --- 1.0.16 2009/06/10
1097 SRU to Z39.50 filter honors x-username and x-password. If only
1098 x-username is given that translates to open authentication (Z39.50v2). If
1099 both x-username and x-password is present that translates to idPass
1100 authentication (Z39.50v3).
1102 New facility to change current working directory (-w).
1104 Update to upstream skeleton of init.d script. Should fix bug #2619.
1106 Filter session_shared now caches records (used to only cache connections
1109 Filter session_shared now invalidates a Z39.50 session if a server
1110 returns -1 hits. This facility was also part of yazproxy and gets around
1111 a bug in Voyager-based Z39.50 servers.
1113 --- 1.0.15 2008/11/18
1115 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1117 --- 1.0.14 2008/06/09
1119 Fixed the value of SRU record schema in searchRetrieve response. It was set
1120 to a fixed value of "dc" before.
1122 Serialize identical SRU requests. This is useful if HTTP client software
1123 fires identical requests against metaproxy.
1125 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1126 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1127 avoid static configuration. This facility is handled by the sru_z3950 module
1128 and the z3950_client module.
1130 Allow maximum number of sockets to be used for a Z39.50 client by the
1131 use of SRU extra parameter x-max-sockets. This facility is handled by the
1132 sru_z3950 module and the z3950_client module.
1134 --- 1.0.13.1 2008/02/29
1136 Simplified check for Boost libraries.
1138 --- 1.0.13 2008/02/29
1140 First Debian package.
1142 The sru_z9350 filter now recognizes SRU parameter z-target as being
1143 a ZURL of the form host/database .
1145 Mergetype may be specified for filter 'multi'.
1147 --- 1.0.12 2007/09/19
1149 Fixed problem in Makefile WRT library specifictions. This could produce
1150 linker errors (when they should not happen).
1152 Fixed bug #1341: MetaProxy returning different results. Problem was that
1153 fix-up of record database did not normalize the database name.
1155 Documentation updates for Windows compilation.
1157 --- 1.0.11 2007/06/14
1159 Fixed problem with logfile being truncated.
1161 --- 1.0.10 2007/05/23
1163 Fixed bug #1136: Access rights not enforced.
1165 Extension for log module. The log category 'access' logs more details.
1166 New category 'user-access' added which is simlar to 'access' but adds
1167 the Z39.50 user as for all entries in a session.
1171 Added support for configurable default/force target/vhost for module Z39.50
1174 --- 1.0.8 2007/01/25
1176 Implemented filter, session_shared, which optimizes usage of Z39.50
1177 sessions and result sets.
1179 New filter, record_transform, which converts MARC/XML records.
1181 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1183 New filter, load_balance, in development.
1185 New filter, zeerex_xplain.
1187 XML framework for config files started.
1189 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1190 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1191 XML config files are checked against RNG and XML Schema's.
1193 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1194 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1195 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1196 explain record to YAZ CQL-to-PQF text config file.
1198 --- 1.0.7 2006/11/07
1200 Added 'timeout' setting for filter frontend_net which specifies the number
1201 of seconds a session is idle before it is closed. Default timeout is
1204 --- 1.0.6 2006/07/07
1206 Database name in records returned set for virt_db/multi filters.
1208 Filter session_shared now functional.
1210 Log filter can be configured to write to a given file using 'filename'
1211 element. Also information category can be specified with 'category'. If
1212 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1215 --- 1.0.5 2006/05/16
1217 Fixed compilation on Windows.
1219 --- 1.0.4 2006/05/16
1221 Added documentation for the hidenavailable option for the multi filter.
1223 --- 1.0.3 2006/05/16
1225 Fixed bug #573: Hide errors for individual servers. If the element
1226 'hideunavailable' is given in the configuration, individual servers
1227 being unavailable are hidden (unless all are unavailable).
1229 Fixed bug #574: Database names are recognised case-sensitively.
1231 Fixed bug #567: Fix up database name in Name-Plus-Record.
1233 Fixed bug #568: Update win/makefile for VS 2005.
1235 Fixed bug #569: Some options throws unknown exception.
1237 --- 1.0.2 2006/04/28
1239 More information about virtual hosts. The 'etc' directory is part of the
1242 --- 1.0.1 2006/04/27
1244 Build instructions for Windows. NMake makefile part of distribution tar.
1246 --- 1.0.0 2006/04/24
1250 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1251 log, multi, query_rewrite, template, virt_db, z3950_client.
1253 Filters in development: session_shared.
1255 Pseudo-filters: template, dl
