3 Fix ref to freed memory in log filter 1line - MP-556
5 echoedSearchRetrieveRequest support MP-555
9 zoom: allow hostname to be given for ipauth MP-552
10 The Torus setting for that is called auth_hostname.
14 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
18 session_shared: close in ~BackendInstance MP-549
19 This fixes a serious issue where some MP would leak sockets.
21 session_shared: mutex lock in BackendClass::release_backend MP-550
22 Fixes a SEGV that could occur (in rare cases).
26 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
28 zoom: fix invalid present response in some cases MP-546
30 zoom: Relay Torus HTTP error message
34 Check for proper limits before using RecordCache functions MP-544
38 Build packages for Ubuntu Trusty Tahr 14.04 LTS
40 sort: crash / invalid_read in filter sort MP-541
42 sru_z3950: facet should be stored in additionalSearchInfo MP-533
44 doc: fix missing man pages MP-542
46 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
48 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
52 sru_z3950: fix facet response (memory corruption) MP-532
54 log: fix crash idPass user is omitted MP-530
58 query_rewrite: pass-thru non Type-1 queries MP-527
60 metaproxy stop (SIGTERM) kills all child processes spanwed by
61 filter (if any) before invoking filter destructors. MP-525
65 http_file: only supports HTTP GET MP-523
67 session_shared: shut down expire thread in destructor
68 This ensures that expire thread is not running after destruction
69 and does bad memory references, etc.
71 frontend_net: fix segfault on startup MP-524
72 Would happen if MP was listening on multiple ports and one
73 of the ports was already in use (and MP would exit).
75 frontend_net: fix memory leak MP-521
76 This leak would occur if all sessions were in use and the input
77 queue was cleared when a client would close connection (socket).
79 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
83 http_rewrite: use local skiplist; fixes memory corruption. MP-520
85 http_client: x-forwarded-for controls X-Forwarded-For presence
86 If x-forwarded-for setting (boolean) is enabled, http_client will
87 generate an X-Forwarded-For header entry which includes existing
88 X-Forwarded-For (if any) and current peer address (immediate client
89 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
90 will not be generated.
92 z3950_client: client_ip controls client-IP presence
93 If client_ip setting (boolean) is enabled, z3950_client will
94 generate a client_ip OID as part of init request which includes
95 previous client_ip (if any) and current peer address (immediate
96 client of Metaproxy). By default client_ip is disabled and client_ip
97 will not be generated.
99 HTTP X-Forwarded-For/Z39.50 Client-IP support
100 virt_db, multi: relays Z39.50 client-IP.
101 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
102 zoom: uses Client-IP or origin address (prefer Client-IP).
103 frontend_net: Strips tcp: from peer address (so that it is no longer
104 printed and stripped in zoom filter).
105 z3950_client: builds client-IP list - combining immediate peer address
106 as returned by COMSTACK and existing client-IP list (if avaiable).
107 The Origin only printes first X-Forwarded address.
111 Log when SIG{TERM,USR1} is received ASAP MP-513
112 Do it in frontend_net event loop rather than in place for metaproxy
113 main, which only exits when all sessions are terminated for SIGUSR1
116 metaproxy-config: quote some RHS values (that might include blanks)
118 Fix leak in sru_z3950 filter - when explain is returned MP-511
120 Allow stylesheet to be given for sru_z3950 filter MP-510
121 This is based on a patch by Sven Porst and the functionality
122 of the YAZ Generic Frontend Server.
124 Allow base attribute in configuration file tags - the attributes are
125 inserted by XInclude usage as mentioned on
126 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
127 and noted in a gist: https://gist.github.com/3551094
129 Package metaproxy provides virtual package metaproxy6 MP-508
130 This allows module packages to depend on a metaproxy server
133 Filter destructors called upon daemon termination MP-505
134 When metaproxy daemon receives SIGTERM the stop method of each filter
135 is called. The stop method existed before, but did not take any
136 arguements (void).. The frontend_net filter can now distinguish
137 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
138 (stop immediately). Note that this changes the API+ABI of Metaproxy
141 zoom: sync up with Pazpar2 WRT authentication handling MP-492
143 Router: use shared_ptr rather than naked one - to avoid leak if an
144 exception is thrown in configure.
148 zoom: Add nocproxy=1 for contentConnector sessions MP-501
150 Doc: mention proper versions; fix link to Boost win binaries.
152 Windows: update for Boost 1.55
154 Windows: avoid warning when using boost::split. Done by defining
155 _SCL_SECURE_NO_WARNINGS for Visual Studio.
157 Fix LSB conformance for /etc/init.d/metaproxy MP-500
158 Debian: add support for /etc/init.d/metaproxy status
160 sort: Add const to Record less than operator in order to compile on
165 session_shared: fix element-set handling in record caching. MP-499
167 document http_rewrite. MP-468
169 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
170 respects the header (which will normally come from the cproxy filter)
174 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
175 RPM was unsable in version 1.4.0.
177 Remove log message about "backend classes". Appeared in version 1.4.0.
181 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
182 with older version from source, but packages now use YAZ 5 that supports
185 sru_z3950: Fix SEGV for decoding invalid SRU requests
186 Incorrect reference to union (was explain response rather than
189 session_shared: match additionalSearchInfo (includes facets). In
190 layman's terms means that means that facets are properly handled
191 by this filter. Eg a change in requested facets will issue new
192 search and facets from exisiting result set are cached.
194 --- 1.3.62 2013/09/11
196 http_rewrite: better handling of <script> content in HTML parser. MP-486
198 http_rewrite: fix threading issue with regex. MP-482
200 bounce: don't use strdup for fixed length content. Error occurred in echo
203 session_shared: expire backend class when no instances left. This
204 means memory clean up, but not really a leak fix.
206 virt_db: fix leak for naked ptr.
208 cql_rpn: use config relative path for cql2rpn file. MP-481
210 Updates for upcoming YAZ 5.
212 --- 1.3.61 2013/08/29
214 New configuration directories ports.d/routes.d for metaproxy
215 configuration. This allows 3rd party packages to install config
216 for ports and new routes. MP-477
218 --- 1.3.60 2013/08/21
220 Fix metaproxy-config --libs to return non-mt over mt libs.
221 The -mt versions do not exist as shared objects and cause
222 linker errors for applications linking with Metaproxy.
223 Problem present in versions 1.3.56 - 1.3.59. MP-475
225 HTML: clean up char checks. Add ptr to HTML parse spec
227 HTML parser stops eating tag when <-char is met MP-473
229 rewrite: do not even compare content types, if we don't have any
230 the regex_match caused a segfault if we had no content-type in the
233 rewrite: within header=... matches only the header value
234 Used to match the whole header line, but we need to use
235 ^$ anchoring for host-relative regexps, and they need to
236 anchor at the ends of the value. MP-470.
238 rewrite: Ruleset functional MP-469
240 --- 1.3.59 2013/07/12
242 session_shared: negotiate init sz parameters.
243 By default, session_shared will honor the paramters given by client.
244 An alternative, but not implemented, algorithm would be to only
245 re-use sessions with same sz parameters. This however, could reduce
246 re-use of sessions a lot. Hence this, simple algorithm instead. The
247 negotiation to a maximum sz values can be enabled by using
248 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
249 in configuration. This will make session_shared send those values
250 to backends and use returned init values in negotaition to
251 client before session_shared.
253 session_shared: resolve result-set references.
254 The reference is substitued with the query for old set if database
255 match and query type is Type-1. If not the reference will issue a
258 sort filter: relays RecordComposition including elementSet in use for
261 http_client: better diagnostics
263 http_client: disables HTTP redirect handling by default.
264 It can be configured with max-redirects in configuration.
266 --- 1.3.58 2013/06/12
268 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
270 --- 1.3.57 2013/06/12
272 Make RouterChain and RouterXML part of public API (libmetaproxy).
274 http_client: honor X-Metaproxy-Proxy as an alternative to
275 the "proxy" configuration. Allows proxy to be set per HTTP request.
277 sru_z3950: For SRU requests recognize x-client prefixes as a way
278 to ingest "database parameters".. The suffix of x-client- serves
279 as database argument name. Multiple may be given. For example:
280 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
281 is turned into Z39.50 database
284 --- 1.3.56 2013/05/27
286 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
288 New filter sd_remove, which replaces surrogate diagnostics with
289 SUTRS records. This filter tries to deal with clients that breaks
290 when receiving surrogate diagnostics.
292 new filter http_client. Same role as z3950_client, but just for
293 HTTP. Allows Metaproxy to operate as a HTTP proxy.
295 New filter http_rewrite1, which serves as purpose on how to rewrite
296 HTTP content with Metaproxy.
298 Use libboost-system if available, because newer versions of libboost-threads
299 requires libboost-system.
301 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
304 --- 1.3.55 2013/04/10
306 zoom: Torus setting: authenticationMode which may hold values "basic"
309 --- 1.3.54 2013/03/27
311 configure: check for Libxslt support in YAZ and rely on definitions
312 from yaz-config, rather than doing own xslt/xml2 checks.
314 Allow timestamp format for log lines to be given with option -m
315 for metaproxy. Similar to yaz-ztest/GFS option -m.
317 Document log category 'line' for log filter.
319 Solr configuration example in etc/config-solr.xml
321 multi: do not mess with request package. For scan and search,
322 database-names were modified and the request package was left with
323 dangling pointers that caused a log filter to fail (request package
324 inspected after multi was invoked).
326 Documentation: fix id of metaproxy-config ref .
328 Documentation: update for USEMARCON support.
330 --- 1.3.53 2013/01/31
332 record_transform: allow OPACXML to OPAC conversion
334 zoom: document content-proxy
336 zoom: document db parm content-{user,password}, torus_url. Also
337 <torus auth_url="..> which makes zoom operate in authenticated mode
340 --- 1.3.52 2012/11/30
342 zoom: fix http://-check. SRU search broken in 1.3.51.
344 --- 1.3.51 2012/11/15
346 zoom: only append http:// for SRU if not already given . Makes it
347 possible to use https-URLs.
349 Use yazpp 1.4 or later due to new ABI.
351 frontend_net: allow max package size to be specified. Controlled by
352 attribute 'max_recv_bytes' of element 'port'.
354 --- 1.3.50 2012/10/29
356 For most generated diagnostics by filters, typically temporary
357 system error, augment addinfo message with filter name.
359 Add support for CentOS 6 packages.
361 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
363 Add man page for metaproxy-config.
365 --- 1.3.49 2012/10/18
367 zoom: new config element passthru. This defines an element set that is
368 passed verbatim to the backend in pz2 mode.
370 auth_simple: allow both idPass and open auth. Also fix SEGV that could
373 --- 1.3.48 2012/10/08
375 z3950_client: fix string handling for init diagnostics in the case where
378 query_rewrite: no charset conversion for error queries. Avoid performing
379 charset conversion for query conversion errors. The resulting Type-1
380 query is invalid in this case.
382 --- 1.3.47 2012/10/04
384 For graceful stop (SIGUSR1), metaproxy will kill children processes.
386 Log when metaproxy is invoked in test mode (-t).
388 Log PID for each log message.
390 multi: combine both NSDs and multiple NSDs into one (diagnostics).
392 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
393 a (backend=target) is appended for each diagnostic so that can be
394 determined the origin of error.
396 multi: hideerrors also in use for present response.
398 Solr example in zoom man page.
400 Fix typo in query_rewrite config example.
402 Log at least first non surrogate diagnostic. Instead of
403 "Z_Records_multipleNSD"
405 multi: Fix check for opt Records in present response. A SEGV could occur
406 if a target did not return records and no diagnostics.
408 --- 1.3.46 2012/09/24
410 Yet another fix for graceful stop.
412 --- 1.3.45 2012/09/12
414 sru_z3950: relay surrogate diagnostics.
416 --- 1.3.44 2012/09/10
418 zoom: Honor extraArgs, strip # in zurl.
420 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
422 zoom: url_recipe allow %{var[reg]} substitutions.
423 It's like ${var[reg]} but does URI component encoding as well.
425 --- 1.3.43 2012/08/22
427 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
428 non-keepalive HTTP sessions.
430 http_file: allow zero size files (bug fix)
432 Fix zoom schema: auth_url is optional
434 --- 1.3.42 2012/08/20
436 zoom: fix un-init memory (could result in SEGV at session close)
438 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
439 and may be used in filters as usual.
441 zoom: authentication via Torus lookup
442 Enabled by new configuration setting: auth_url . If this is defined,
443 the zoom module will contact Torus for auth/IP lookup and that will
444 define realm to be used in session.
446 --- 1.3.41 2012/08/10
448 virt_db: Fix database name - first character we removed by mistake.
449 Bug introduced in 1.3.40.
451 --- 1.3.40 2012/08/06
453 virt_db: Don't use "unix path" as database for Unix sockets.
455 --- 1.3.39 2012/08/02
457 z3950_client: Don't tamper with / in zurl - fixes problems
458 using Unix sockets for backends.
460 session_shared: fix integer overflow problem with hit count.
462 session_shared: avoid long usage of cached queries.
464 zoom: New database argument , torus_url to set URL of Torus
465 record to be fetched.
467 --- 1.3.38 2012/07/04
469 Fixes for 'metaproxy reload' for RPM/Debian packages.
471 zoom: Allow rpn2cql conversion to be augmented with a properties file.
472 Element rpn2cql can be specified per-target for the zoom filter.
474 log: New category "line" which is a single-line log message with
475 most important parts of a HTTP/Z39.50 request/response.
477 --- 1.3.37 2012/06/01
479 frontend_net: add facility to report live statistics about response
480 times and current thread usage. The report is an XML document
481 and is triggered for a specific URL path. This is set by <stat-req>
482 in the configuration of frontend_net. By default this report is
483 disabled (same as empty value for <stat-req>).
485 Fix reload problem in init.d script for RPM/Debian.
486 The '/etc/init.d/metaproxy reload' in some cases would stop but not
487 start metaproxy - effectively stopping the service.
489 Don't display start log message when config testing (-t).
491 zoom: avoid CCL message limit of 1K in ZOOM filter.
493 --- 1.3.36 2012/05/10
495 metaproxy init script reacts to reload which does graceful stop +
496 start and is used by logrorate script.
498 --- 1.3.35 2012/05/09
500 Fixes for Windows compilation.
502 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
503 existing sessions running but terminate the monitor process that is
504 used in keepalive mode.
506 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
507 before. Consistent with 'metaproxy stop' message.
509 zoom: document zoom's proxy_timeout
511 z3950_client: fixup addinfo for init response
513 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
514 "Access to specified database denied" is returned, but only if init
515 response from backend does not carry diagnostics already.
517 multi: relays user info for first rejected target. The other-information
518 field for init response for first rejected target is in common init
519 response. This ensures that some backend init diagnostics are returned to
522 --- 1.3.34 2012/04/25
524 frontend_log: extend logging (when message is given in config).
526 --- 1.3.33 2012/04/25
528 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
530 --- 1.3.32 2012/04/24
532 sru_z3950 filter passes through incoming Z39.50 requests again. Was
533 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
535 --- 1.3.31 2012/04/24
537 zoom: fixes for retry/proxy failover logic. More logging.
539 --- 1.3.30 2012/04/23
541 zoom: return addinfo="proxy failure" for proxy failures. This also
542 changes the scheme for dealing with proxies a bit. zoom now always
543 do proxy check, even if there's no failover. Fortunately, that's not
546 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
547 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
548 generic. We don't know why the init would fail; IP, user, block IP, etc.
549 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
551 zoom: guess if invalid SRU response was an auth failure
553 session_shared: disable session retry by default . Can be enabled by
554 restart="true" in resultset section.
556 --- 1.3.29 2012/04/18
558 zoom: may read cf-proxy's config settings.
559 This reduces manual configuration of the content proxy server host.
560 The ZOOM module will use the old style session.proxyhost if "server"
561 is given (deprecated) and use the new style proxyhost/session if
562 "config_file" is in use.
564 frontend_net: remove incoming requests that can not be handled
565 Requests in queue for filter frontend_net are removed if client
566 closes connection for the session and request is not yet handled.
568 sru_z3950: serialize requests. This is to ensure that pipelined
569 HTTP requests are handled properly.
571 --- 1.3.28 2012/04/04
573 New class, wrbuf, that wraps YAZ' WRBUF.
575 --- 1.3.27 2012/03/30
577 Metaproxy daemon is now running as user "metaproxy". This user is
578 managed by package maintainer scripts. The user information is stored
579 in /etc/metaproxy/metaproxy.user .
581 --- 1.3.26 2012/03/20
583 New filter, sort, that allows sorting of XML records via Z39.50
586 Filter record_transform: USEMarcon support. For example:
587 <retrieval syntax="usmarc">
588 <backend syntax="unimarc" name="F">
589 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
593 Filter multi: empty route pattern uses route as default.
595 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
596 may use the shorter notation
597 <target route="z3950.indexdata.com"/>
599 Filter query_rewrite: use config path to locate XSLT.
601 Filter frontend_net: log statistics.
602 If a custom message element in frontend_net configuration it makes
603 the frontend_net filter produce a log entry whenever an operation
604 is completed. The log is always written using yaz_log with the
605 custom message given, the package ID (session ID) , the time
606 the operation has been active (end-to-end) , the threads currently
607 active/total and the size of the request input/output queues.
609 query_rewrite: charset conversion of query terms.
610 This is an optional feature. Enabled by element <charset> in
611 configuration with attribute 'from' and 'to' that specifies
612 from/to encodings. The default 'from' encoding is UTF-8.
614 Filter record_transform: honor piggyback searches.
616 Filter zoom: re-connect when database is reused.
617 Re-connect is necessary if a connection is lost or a timeout occurs.
618 If not, we'll be seeing zero hits, when we shouldn't.
620 --- 1.3.25 2012/02/29
622 zoom: Change scheme for dealing with content proxy URLs. The module
623 now has its own common XSL transform that is enabled by record_xsl
624 attribute in the configuration. This XSL gets parameter cproxyhost
625 that holds the host for the content proxy session . The genearted-url
626 is created only if urlRecipe is enabled. In previous version default
627 value of urlRecipe was ${md-electronic-url}; it is now empty and
628 disabled by default. Also generated-url no longer includes the content
629 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
632 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
633 connections. Default value is 40 (seconds).
635 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
636 "Malformed query" for syntax errors and related ones; throw
637 Bib-1: 3 "Unsupported search" for everything else. Details from
638 the CCL parser is provided as additional-info.
640 multi: new setting hideerrors that makes multi only relay diagnostics
641 to a client if all backends fail.
643 --- 1.3.24 2012/02/23
645 zoom: empty ccl_map field-mappings disables CCL map.
647 zoom: fix Explain search that could return error if session was
650 --- 1.3.23 2012/02/10
652 zoom: returns Explain records for database IR-Explain---1. The
653 target profile records are converted to Explain records via XSLT.
655 session_shared: make error recovery configurable. Whether a search
656 is restarted on errors or not, is configurable by attribute "restart"
657 in element "resultset" in configuration.
659 session_shared: only relay init for first request. session_shared, for
660 each backend class, now only relays first init request (rather than all).
661 The module only needs to save init response info once. This avoids the
662 need to check for session max.
664 --- 1.3.22 2012/02/02
666 zoom: fix memory leaks.
668 session_shared: maximum number of sessons is configurable. Default
669 value is 100. Result-sets for backends without named result sets are
670 only re-used if databases is identical for a search. This is under the
671 assumption that performance may suffer for those backends when
672 changing the database for each search.
674 multi: combines diagnostics from all backends. All diagnostics from
675 backends are combined into multiple non-surrogate diagnostics; rather
676 than just one diagnostic from first backend.
678 --- 1.3.21 2011/12/27
680 zoom: relay realm to cproxy parameter file.
682 Configuration: Allow filter collection element inside route. This
683 makes it possible to include multiple filters at once.
685 zoom: nocproxy also disables urlRecipe.
687 --- 1.3.20 2011/12/21
689 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
690 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
691 90: "Unsupported direction value".
693 zoom: honor database argument nocproxy. This disables creating a content
694 connector session (for non-CF targets, usually) and also relays nocproxy
695 as database argument to a CF target.
697 --- 1.3.19 2011/12/16
699 zoom: Multiple proxy hosts may be given for proxy rich database
700 parameter. List is comma separated.
702 http_file: decodes URI paths properly. Does not return 404: not found
703 if no prefix are matches. Instead packages are passed on.
705 --- 1.3.18 2011/12/08
707 zoom: content-{user,password,proxy} are passed on to content proxy
708 system and takes precedence over user,password,proxy .
710 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
711 with a log element including log material from children filters. At
712 this point, only the zoom filter uses this log facility. It will
713 eventually be used by other filters as well. In particular it might be
714 useful for this feature to track all filters in used during a search.
716 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
717 and queries as they are manipulated are logged.
719 zoom: extend addinfo with native diagnostics. Diagnostics as received
720 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
721 diagnostics. This indicates both a backend diagnostic and the original
724 zoom: default urlRecipe value is ${md-electronic-url}
726 zoom: target profile setting sruVersion is recognized.
728 --- 1.3.17 2011/11/17
730 zoom: log target profile record fetched (AKA Torus).
732 --- 1.3.16 2011/11/17
734 Change target profile parameter CfSubDb to CfSubDB.
736 --- 1.3.15 2011/11/12
738 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
739 makes sense to the zoom module itself).
741 --- 1.3.14 2011/11/11
743 zoom: realm may be given as part of database.
745 --- 1.3.13 2011/10/26
747 Fix Origin class assigment method; was removd by mistake in 1.3.12.
749 --- 1.3.12 2011/10/26
751 zoom: database args x-name=value are passed through to backend database.
753 SRU filter: user may specify session ID that is passed to log entries
754 that follows. It is specified by using x-session-id in the SRU arguments.
756 zoom: fix null pointer reference which would occur for bad url parameter
757 inside "torus" or if url was not given.
759 --- 1.3.11 2011/09/09
760 Fix bug in filter session_shared where sessions would not expire
761 properly (session ttl). This in turn could make the target close the
762 connection before expected and session_shared would return diagnostic
763 2: system temporarily available.
765 --- 1.3.10 2011/09/09
767 zoom: new target profile setting: sortmap_field. If sortmap_field is given
768 the field is mapped to the value for the sortmap. Values not matching
769 sortmap_field are passed verbatim.
771 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
772 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
773 depending on whether RPN or CQL is actually sent to the target.
777 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
779 zoom: For content proxy authentication is stored in param name
780 "auth", instead of "authentication".
784 zoom: relay schema in SRU mode. Previously recordSchema was not affected
789 zoom: new target profile element literalTransform that holds XSLT
790 (encoded as string) for target. Only if present and non-zero length it is
791 considered present. This takes precedence over transform.
793 Don't rely on trang anymore for Git checkout builds. Configuration in etc
794 will only be properly validated if trang is available. From now on only
795 relax NC files are bundled with the source dist.
797 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
798 component was not detected when it should be.
802 z3950_client: mark non-surrogate diagnostics from backend.
804 zoom: a proxy may be specified for HTTP fetch of target profiles.
808 Honor piggyback. Makes some SRU targets behave that insist on
809 maximumRecords > 0, but also increases performance.
813 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
814 file was not update for libdir/metaproxy4 in version 1.3.2.
818 Change location of Metaproxy modules from libdir/metaproxy to
819 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
820 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
822 New facility to dump APDUs from zoom filter. Enabled by
823 <log apdu="true"/> in the zoom filter configuation.
825 zoom filter bug fix: SRU diagnostics received from backend was
826 not properly converted to Bib-1 diagnostics.
828 Package metaproxy depends on libmetaproxy4, same version.
832 zoom: fix a bug WRT passing authentication parameters to backends.
836 Fixes for windows Makefile.
838 --- 1.2.10 2011/07/25
840 Change major version of metaproxy library from 3 to 4. This in turn
841 makes new package names for Debian and RPM.
845 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
848 zoom: configurable element sets for record transforms.
850 zoom: the target profile based transform is specified by element_transform
851 in element torus of of the ZOOM filter configuration ; default value
852 is "pz2". Target profile based retrieval is specified by element_raw
853 in configuration. It will perform same steps, but omit the XSL transform.
854 Default value is "raw".
856 zoom: element set is omitted if not set in profile. But only if pz2
857 transform is in effect. Previously the default element set was to "F".
859 zoom: For non-CF targets database arguments are parsed. User may supply
860 db,user=myuser&password=mypass for non-CF targets. These values override
861 what's given the authentication from the target profile.
863 session_shared: fix reference to freed memory. Would occur if a search
864 response had non-surrogate diagnostics.
868 Route may be given for each port in frontend_net.
872 Documentation for zoom filter. Local target profiles may be specified.
874 Fixes for zoom filter.
878 First version with zoom filter.
882 Filter z3950_client may be configured to always send a close APDU
883 to backend target when connection/session is closed. This will only
884 happen if close APDU is not already sent. Enabled by configuration
885 for z3950_client (force_close).
887 Filter virt_db and multi: relay close APDU.
889 Filter virt_db and multi: relay init size parameters
890 preferredMessageSize and maximumRecordSize.
892 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
896 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
898 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
899 as determined by configure.
901 RPM: Release includes 'indexdata' name. Use indexdata in release name so
902 this package can be distinguished from other vendors.
906 Fix filter multi: relay idAuthentication parameters.
910 Add metaproxy-config for returning compiler flags, libraries.
914 Fix --with-boost=PREFIX .
918 session_shared: fix use of maintenance thread.
920 Introduce 'start' method for filters and routers. It gets called after
921 configure and after fork, but before processing. This changes API -
922 from libmetaproxy2 to libmetaproxy3.
926 session_shared: ensure backend session is closed if init rejected
929 z3950_client: fix NULL ptr reference that could occur if two clients
930 connected concurrently and if max-sockets was in effect.
934 Fix bug 3497 - Metaproxy unstable while stopping.
936 Fix bug 3495 - SEGV in SRU filter.
940 Filter multi throws diagnostic 'Present Out of Range' when
941 appropriate - rather than returning 0 records.
943 Filter virt_db: fix bad result reuse. Could happen if a result
944 was overriden and a backend did not supported named result sets.
948 Filter log: category access logs diagnostics even if searchStatus
949 or presentStatus is 'success'.
953 The SRU to Z39.50 filter does repeated Z39.50 present requests
954 to fetch all records. Needed when a Z39.50 server returns partial
955 results (due to message size limits).
959 Metaproxy now kills all child processes that are spawned by
960 modules (in case of fork, exec).
964 Debian package now installs /etc/metaproxy/metaproxy.xml which
965 includes all XML files /etc/metaproxy/filters-enabled .
966 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
970 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
971 development package to facilitate 3rd party Metaproxy modules.
973 --- 1.0.23 2010/01/04
975 Filter virt_db: Close backend filter session when Init rejected is received
976 from it (in which case it's not really closed yet). This will ensure we don't
977 run out of resources such as FDs in this case.
979 sru_z3950 filter: Accept any database (including those not listed).
981 --- 1.0.22 2009/12/03
983 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
984 later which means YAZ 3.0.47 or later.
986 --- 1.0.20 2009/11/19
988 For filter virt_db, the database is a glob pattern and the virtual
989 database sections are consulted in the order given.
991 --- 1.0.19 2009/07/08
993 For filter multi, the target (for routing) may be given as a glob-pattern.
995 More documentation for filters virt_db and multi.
997 Update schema to allow for no database in sru_z3950 filter.
999 --- 1.0.18 2009/06/30
1001 Added limit filter to put sleep (penalty) for heavy use.
1003 Filter frontend_net may be configured to limit the number of new connections
1004 from same IP to some value (connect-max).
1006 Fixed the load_balance filter.
1008 --- 1.0.17 2009/06/16
1010 Fix path for metaproxy executable for Debian init.d script.
1012 --- 1.0.16 2009/06/10
1014 SRU to Z39.50 filter honors x-username and x-password. If only
1015 x-username is given that translates to open authentication (Z39.50v2). If
1016 both x-username and x-password is present that translates to idPass
1017 authentication (Z39.50v3).
1019 New facility to change current working directory (-w).
1021 Update to upstream skeleton of init.d script. Should fix bug #2619.
1023 Filter session_shared now caches records (used to only cache connections
1026 Filter session_shared now invalidates a Z39.50 session if a server
1027 returns -1 hits. This facility was also part of yazproxy and gets around
1028 a bug in Voyager-based Z39.50 servers.
1030 --- 1.0.15 2008/11/18
1032 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1034 --- 1.0.14 2008/06/09
1036 Fixed the value of SRU record schema in searchRetrieve response. It was set
1037 to a fixed value of "dc" before.
1039 Serialize identical SRU requests. This is useful if HTTP client software
1040 fires identical requests against metaproxy.
1042 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1043 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1044 avoid static configuration. This facility is handled by the sru_z3950 module
1045 and the z3950_client module.
1047 Allow maximum number of sockets to be used for a Z39.50 client by the
1048 use of SRU extra parameter x-max-sockets. This facility is handled by the
1049 sru_z3950 module and the z3950_client module.
1051 --- 1.0.13.1 2008/02/29
1053 Simplified check for Boost libraries.
1055 --- 1.0.13 2008/02/29
1057 First Debian package.
1059 The sru_z9350 filter now recognizes SRU parameter z-target as being
1060 a ZURL of the form host/database .
1062 Mergetype may be specified for filter 'multi'.
1064 --- 1.0.12 2007/09/19
1066 Fixed problem in Makefile WRT library specifictions. This could produce
1067 linker errors (when they should not happen).
1069 Fixed bug #1341: MetaProxy returning different results. Problem was that
1070 fix-up of record database did not normalize the database name.
1072 Documentation updates for Windows compilation.
1074 --- 1.0.11 2007/06/14
1076 Fixed problem with logfile being truncated.
1078 --- 1.0.10 2007/05/23
1080 Fixed bug #1136: Access rights not enforced.
1082 Extension for log module. The log category 'access' logs more details.
1083 New category 'user-access' added which is simlar to 'access' but adds
1084 the Z39.50 user as for all entries in a session.
1088 Added support for configurable default/force target/vhost for module Z39.50
1091 --- 1.0.8 2007/01/25
1093 Implemented filter, session_shared, which optimizes usage of Z39.50
1094 sessions and result sets.
1096 New filter, record_transform, which converts MARC/XML records.
1098 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1100 New filter, load_balance, in development.
1102 New filter, zeerex_xplain.
1104 XML framework for config files started.
1106 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1107 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1108 XML config files are checked against RNG and XML Schema's.
1110 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1111 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1112 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1113 explain record to YAZ CQL-to-PQF text config file.
1115 --- 1.0.7 2006/11/07
1117 Added 'timeout' setting for filter frontend_net which specifies the number
1118 of seconds a session is idle before it is closed. Default timeout is
1121 --- 1.0.6 2006/07/07
1123 Database name in records returned set for virt_db/multi filters.
1125 Filter session_shared now functional.
1127 Log filter can be configured to write to a given file using 'filename'
1128 element. Also information category can be specified with 'category'. If
1129 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1132 --- 1.0.5 2006/05/16
1134 Fixed compilation on Windows.
1136 --- 1.0.4 2006/05/16
1138 Added documentation for the hidenavailable option for the multi filter.
1140 --- 1.0.3 2006/05/16
1142 Fixed bug #573: Hide errors for individual servers. If the element
1143 'hideunavailable' is given in the configuration, individual servers
1144 being unavailable are hidden (unless all are unavailable).
1146 Fixed bug #574: Database names are recognised case-sensitively.
1148 Fixed bug #567: Fix up database name in Name-Plus-Record.
1150 Fixed bug #568: Update win/makefile for VS 2005.
1152 Fixed bug #569: Some options throws unknown exception.
1154 --- 1.0.2 2006/04/28
1156 More information about virtual hosts. The 'etc' directory is part of the
1159 --- 1.0.1 2006/04/27
1161 Build instructions for Windows. NMake makefile part of distribution tar.
1163 --- 1.0.0 2006/04/24
1167 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1168 log, multi, query_rewrite, template, virt_db, z3950_client.
1170 Filters in development: session_shared.
1172 Pseudo-filters: template, dl
