3 Use YAZ backtrace facility MP-582
5 Fix libmetaproxy-dev depends on libgnutls-dev - MP-580
6 libgnutls-dev is unavailable on jessie.
8 Update template filter to avoid Pimpl MP-579
10 cgi: POSTed content - part of MP-562
12 Fix filter cgi does not relay session close MP-577
16 Add support for binding outgoing IP for http_client and z3950_client
17 This is enabled by bind_host setting. MP-575
21 z3950_client: allows negotiation charset to be set MP-574
23 cgi: more functional but no support for POSTed content yet (part of MP-564)
27 http_file: add include of sys/stat.h fixes MP-576
29 Fix documentation about SRU client support MP-572
31 Initialize Libxml2 - for threaded operation MP-571
35 On SIGTERM shut down connection+listening sockets MP-568
36 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
40 zoom: make retry on failure configurable MP-565
41 The default and existing behavior is that backend failures (any
42 diagnostic) makes the module re-search once. The behavior may
43 be changed by db parameter 'retry'. If given value '0' disables
44 retry and '1' enables it. If not given, the Torus record may
45 specify with element retryOnFailure (value '0'/'1').
49 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
50 instead of just a child process. Extremely rare in real life, hit me with
51 CF stress testing. MP-559.
55 http_file: passthru option MP-557
56 New facility for http_file to passthru - even if an area is matched. The
57 default behavior (passthru=false) is to return 404: Not found. With
58 passthru=false, next filter is consulted.
62 Fix ref to freed memory in log filter 1line - MP-556
64 echoedSearchRetrieveRequest support MP-555
68 zoom: allow hostname to be given for ipauth MP-552
69 The Torus setting for that is called auth_hostname.
73 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
77 session_shared: close in ~BackendInstance MP-549
78 This fixes a serious issue where some MP would leak sockets.
80 session_shared: mutex lock in BackendClass::release_backend MP-550
81 Fixes a SEGV that could occur (in rare cases).
85 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
87 zoom: fix invalid present response in some cases MP-546
89 zoom: Relay Torus HTTP error message
93 Check for proper limits before using RecordCache functions MP-544
97 Build packages for Ubuntu Trusty Tahr 14.04 LTS
99 sort: crash / invalid_read in filter sort MP-541
101 sru_z3950: facet should be stored in additionalSearchInfo MP-533
103 doc: fix missing man pages MP-542
105 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
107 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
111 sru_z3950: fix facet response (memory corruption) MP-532
113 log: fix crash idPass user is omitted MP-530
117 query_rewrite: pass-thru non Type-1 queries MP-527
119 metaproxy stop (SIGTERM) kills all child processes spanwed by
120 filter (if any) before invoking filter destructors. MP-525
124 http_file: only supports HTTP GET MP-523
126 session_shared: shut down expire thread in destructor
127 This ensures that expire thread is not running after destruction
128 and does bad memory references, etc.
130 frontend_net: fix segfault on startup MP-524
131 Would happen if MP was listening on multiple ports and one
132 of the ports was already in use (and MP would exit).
134 frontend_net: fix memory leak MP-521
135 This leak would occur if all sessions were in use and the input
136 queue was cleared when a client would close connection (socket).
138 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
142 http_rewrite: use local skiplist; fixes memory corruption. MP-520
144 http_client: x-forwarded-for controls X-Forwarded-For presence
145 If x-forwarded-for setting (boolean) is enabled, http_client will
146 generate an X-Forwarded-For header entry which includes existing
147 X-Forwarded-For (if any) and current peer address (immediate client
148 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
149 will not be generated.
151 z3950_client: client_ip controls client-IP presence
152 If client_ip setting (boolean) is enabled, z3950_client will
153 generate a client_ip OID as part of init request which includes
154 previous client_ip (if any) and current peer address (immediate
155 client of Metaproxy). By default client_ip is disabled and client_ip
156 will not be generated.
158 HTTP X-Forwarded-For/Z39.50 Client-IP support
159 virt_db, multi: relays Z39.50 client-IP.
160 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
161 zoom: uses Client-IP or origin address (prefer Client-IP).
162 frontend_net: Strips tcp: from peer address (so that it is no longer
163 printed and stripped in zoom filter).
164 z3950_client: builds client-IP list - combining immediate peer address
165 as returned by COMSTACK and existing client-IP list (if avaiable).
166 The Origin only printes first X-Forwarded address.
170 Log when SIG{TERM,USR1} is received ASAP MP-513
171 Do it in frontend_net event loop rather than in place for metaproxy
172 main, which only exits when all sessions are terminated for SIGUSR1
175 metaproxy-config: quote some RHS values (that might include blanks)
177 Fix leak in sru_z3950 filter - when explain is returned MP-511
179 Allow stylesheet to be given for sru_z3950 filter MP-510
180 This is based on a patch by Sven Porst and the functionality
181 of the YAZ Generic Frontend Server.
183 Allow base attribute in configuration file tags - the attributes are
184 inserted by XInclude usage as mentioned on
185 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
186 and noted in a gist: https://gist.github.com/3551094
188 Package metaproxy provides virtual package metaproxy6 MP-508
189 This allows module packages to depend on a metaproxy server
192 Filter destructors called upon daemon termination MP-505
193 When metaproxy daemon receives SIGTERM the stop method of each filter
194 is called. The stop method existed before, but did not take any
195 arguements (void).. The frontend_net filter can now distinguish
196 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
197 (stop immediately). Note that this changes the API+ABI of Metaproxy
200 zoom: sync up with Pazpar2 WRT authentication handling MP-492
202 Router: use shared_ptr rather than naked one - to avoid leak if an
203 exception is thrown in configure.
207 zoom: Add nocproxy=1 for contentConnector sessions MP-501
209 Doc: mention proper versions; fix link to Boost win binaries.
211 Windows: update for Boost 1.55
213 Windows: avoid warning when using boost::split. Done by defining
214 _SCL_SECURE_NO_WARNINGS for Visual Studio.
216 Fix LSB conformance for /etc/init.d/metaproxy MP-500
217 Debian: add support for /etc/init.d/metaproxy status
219 sort: Add const to Record less than operator in order to compile on
224 session_shared: fix element-set handling in record caching. MP-499
226 document http_rewrite. MP-468
228 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
229 respects the header (which will normally come from the cproxy filter)
233 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
234 RPM was unsable in version 1.4.0.
236 Remove log message about "backend classes". Appeared in version 1.4.0.
240 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
241 with older version from source, but packages now use YAZ 5 that supports
244 sru_z3950: Fix SEGV for decoding invalid SRU requests
245 Incorrect reference to union (was explain response rather than
248 session_shared: match additionalSearchInfo (includes facets). In
249 layman's terms means that means that facets are properly handled
250 by this filter. Eg a change in requested facets will issue new
251 search and facets from exisiting result set are cached.
253 --- 1.3.62 2013/09/11
255 http_rewrite: better handling of <script> content in HTML parser. MP-486
257 http_rewrite: fix threading issue with regex. MP-482
259 bounce: don't use strdup for fixed length content. Error occurred in echo
262 session_shared: expire backend class when no instances left. This
263 means memory clean up, but not really a leak fix.
265 virt_db: fix leak for naked ptr.
267 cql_rpn: use config relative path for cql2rpn file. MP-481
269 Updates for upcoming YAZ 5.
271 --- 1.3.61 2013/08/29
273 New configuration directories ports.d/routes.d for metaproxy
274 configuration. This allows 3rd party packages to install config
275 for ports and new routes. MP-477
277 --- 1.3.60 2013/08/21
279 Fix metaproxy-config --libs to return non-mt over mt libs.
280 The -mt versions do not exist as shared objects and cause
281 linker errors for applications linking with Metaproxy.
282 Problem present in versions 1.3.56 - 1.3.59. MP-475
284 HTML: clean up char checks. Add ptr to HTML parse spec
286 HTML parser stops eating tag when <-char is met MP-473
288 rewrite: do not even compare content types, if we don't have any
289 the regex_match caused a segfault if we had no content-type in the
292 rewrite: within header=... matches only the header value
293 Used to match the whole header line, but we need to use
294 ^$ anchoring for host-relative regexps, and they need to
295 anchor at the ends of the value. MP-470.
297 rewrite: Ruleset functional MP-469
299 --- 1.3.59 2013/07/12
301 session_shared: negotiate init sz parameters.
302 By default, session_shared will honor the paramters given by client.
303 An alternative, but not implemented, algorithm would be to only
304 re-use sessions with same sz parameters. This however, could reduce
305 re-use of sessions a lot. Hence this, simple algorithm instead. The
306 negotiation to a maximum sz values can be enabled by using
307 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
308 in configuration. This will make session_shared send those values
309 to backends and use returned init values in negotaition to
310 client before session_shared.
312 session_shared: resolve result-set references.
313 The reference is substitued with the query for old set if database
314 match and query type is Type-1. If not the reference will issue a
317 sort filter: relays RecordComposition including elementSet in use for
320 http_client: better diagnostics
322 http_client: disables HTTP redirect handling by default.
323 It can be configured with max-redirects in configuration.
325 --- 1.3.58 2013/06/12
327 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
329 --- 1.3.57 2013/06/12
331 Make RouterChain and RouterXML part of public API (libmetaproxy).
333 http_client: honor X-Metaproxy-Proxy as an alternative to
334 the "proxy" configuration. Allows proxy to be set per HTTP request.
336 sru_z3950: For SRU requests recognize x-client prefixes as a way
337 to ingest "database parameters".. The suffix of x-client- serves
338 as database argument name. Multiple may be given. For example:
339 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
340 is turned into Z39.50 database
343 --- 1.3.56 2013/05/27
345 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
347 New filter sd_remove, which replaces surrogate diagnostics with
348 SUTRS records. This filter tries to deal with clients that breaks
349 when receiving surrogate diagnostics.
351 new filter http_client. Same role as z3950_client, but just for
352 HTTP. Allows Metaproxy to operate as a HTTP proxy.
354 New filter http_rewrite1, which serves as purpose on how to rewrite
355 HTTP content with Metaproxy.
357 Use libboost-system if available, because newer versions of libboost-threads
358 requires libboost-system.
360 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
363 --- 1.3.55 2013/04/10
365 zoom: Torus setting: authenticationMode which may hold values "basic"
368 --- 1.3.54 2013/03/27
370 configure: check for Libxslt support in YAZ and rely on definitions
371 from yaz-config, rather than doing own xslt/xml2 checks.
373 Allow timestamp format for log lines to be given with option -m
374 for metaproxy. Similar to yaz-ztest/GFS option -m.
376 Document log category 'line' for log filter.
378 Solr configuration example in etc/config-solr.xml
380 multi: do not mess with request package. For scan and search,
381 database-names were modified and the request package was left with
382 dangling pointers that caused a log filter to fail (request package
383 inspected after multi was invoked).
385 Documentation: fix id of metaproxy-config ref .
387 Documentation: update for USEMARCON support.
389 --- 1.3.53 2013/01/31
391 record_transform: allow OPACXML to OPAC conversion
393 zoom: document content-proxy
395 zoom: document db parm content-{user,password}, torus_url. Also
396 <torus auth_url="..> which makes zoom operate in authenticated mode
399 --- 1.3.52 2012/11/30
401 zoom: fix http://-check. SRU search broken in 1.3.51.
403 --- 1.3.51 2012/11/15
405 zoom: only append http:// for SRU if not already given . Makes it
406 possible to use https-URLs.
408 Use yazpp 1.4 or later due to new ABI.
410 frontend_net: allow max package size to be specified. Controlled by
411 attribute 'max_recv_bytes' of element 'port'.
413 --- 1.3.50 2012/10/29
415 For most generated diagnostics by filters, typically temporary
416 system error, augment addinfo message with filter name.
418 Add support for CentOS 6 packages.
420 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
422 Add man page for metaproxy-config.
424 --- 1.3.49 2012/10/18
426 zoom: new config element passthru. This defines an element set that is
427 passed verbatim to the backend in pz2 mode.
429 auth_simple: allow both idPass and open auth. Also fix SEGV that could
432 --- 1.3.48 2012/10/08
434 z3950_client: fix string handling for init diagnostics in the case where
437 query_rewrite: no charset conversion for error queries. Avoid performing
438 charset conversion for query conversion errors. The resulting Type-1
439 query is invalid in this case.
441 --- 1.3.47 2012/10/04
443 For graceful stop (SIGUSR1), metaproxy will kill children processes.
445 Log when metaproxy is invoked in test mode (-t).
447 Log PID for each log message.
449 multi: combine both NSDs and multiple NSDs into one (diagnostics).
451 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
452 a (backend=target) is appended for each diagnostic so that can be
453 determined the origin of error.
455 multi: hideerrors also in use for present response.
457 Solr example in zoom man page.
459 Fix typo in query_rewrite config example.
461 Log at least first non surrogate diagnostic. Instead of
462 "Z_Records_multipleNSD"
464 multi: Fix check for opt Records in present response. A SEGV could occur
465 if a target did not return records and no diagnostics.
467 --- 1.3.46 2012/09/24
469 Yet another fix for graceful stop.
471 --- 1.3.45 2012/09/12
473 sru_z3950: relay surrogate diagnostics.
475 --- 1.3.44 2012/09/10
477 zoom: Honor extraArgs, strip # in zurl.
479 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
481 zoom: url_recipe allow %{var[reg]} substitutions.
482 It's like ${var[reg]} but does URI component encoding as well.
484 --- 1.3.43 2012/08/22
486 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
487 non-keepalive HTTP sessions.
489 http_file: allow zero size files (bug fix)
491 Fix zoom schema: auth_url is optional
493 --- 1.3.42 2012/08/20
495 zoom: fix un-init memory (could result in SEGV at session close)
497 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
498 and may be used in filters as usual.
500 zoom: authentication via Torus lookup
501 Enabled by new configuration setting: auth_url . If this is defined,
502 the zoom module will contact Torus for auth/IP lookup and that will
503 define realm to be used in session.
505 --- 1.3.41 2012/08/10
507 virt_db: Fix database name - first character we removed by mistake.
508 Bug introduced in 1.3.40.
510 --- 1.3.40 2012/08/06
512 virt_db: Don't use "unix path" as database for Unix sockets.
514 --- 1.3.39 2012/08/02
516 z3950_client: Don't tamper with / in zurl - fixes problems
517 using Unix sockets for backends.
519 session_shared: fix integer overflow problem with hit count.
521 session_shared: avoid long usage of cached queries.
523 zoom: New database argument , torus_url to set URL of Torus
524 record to be fetched.
526 --- 1.3.38 2012/07/04
528 Fixes for 'metaproxy reload' for RPM/Debian packages.
530 zoom: Allow rpn2cql conversion to be augmented with a properties file.
531 Element rpn2cql can be specified per-target for the zoom filter.
533 log: New category "line" which is a single-line log message with
534 most important parts of a HTTP/Z39.50 request/response.
536 --- 1.3.37 2012/06/01
538 frontend_net: add facility to report live statistics about response
539 times and current thread usage. The report is an XML document
540 and is triggered for a specific URL path. This is set by <stat-req>
541 in the configuration of frontend_net. By default this report is
542 disabled (same as empty value for <stat-req>).
544 Fix reload problem in init.d script for RPM/Debian.
545 The '/etc/init.d/metaproxy reload' in some cases would stop but not
546 start metaproxy - effectively stopping the service.
548 Don't display start log message when config testing (-t).
550 zoom: avoid CCL message limit of 1K in ZOOM filter.
552 --- 1.3.36 2012/05/10
554 metaproxy init script reacts to reload which does graceful stop +
555 start and is used by logrorate script.
557 --- 1.3.35 2012/05/09
559 Fixes for Windows compilation.
561 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
562 existing sessions running but terminate the monitor process that is
563 used in keepalive mode.
565 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
566 before. Consistent with 'metaproxy stop' message.
568 zoom: document zoom's proxy_timeout
570 z3950_client: fixup addinfo for init response
572 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
573 "Access to specified database denied" is returned, but only if init
574 response from backend does not carry diagnostics already.
576 multi: relays user info for first rejected target. The other-information
577 field for init response for first rejected target is in common init
578 response. This ensures that some backend init diagnostics are returned to
581 --- 1.3.34 2012/04/25
583 frontend_log: extend logging (when message is given in config).
585 --- 1.3.33 2012/04/25
587 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
589 --- 1.3.32 2012/04/24
591 sru_z3950 filter passes through incoming Z39.50 requests again. Was
592 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
594 --- 1.3.31 2012/04/24
596 zoom: fixes for retry/proxy failover logic. More logging.
598 --- 1.3.30 2012/04/23
600 zoom: return addinfo="proxy failure" for proxy failures. This also
601 changes the scheme for dealing with proxies a bit. zoom now always
602 do proxy check, even if there's no failover. Fortunately, that's not
605 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
606 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
607 generic. We don't know why the init would fail; IP, user, block IP, etc.
608 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
610 zoom: guess if invalid SRU response was an auth failure
612 session_shared: disable session retry by default . Can be enabled by
613 restart="true" in resultset section.
615 --- 1.3.29 2012/04/18
617 zoom: may read cf-proxy's config settings.
618 This reduces manual configuration of the content proxy server host.
619 The ZOOM module will use the old style session.proxyhost if "server"
620 is given (deprecated) and use the new style proxyhost/session if
621 "config_file" is in use.
623 frontend_net: remove incoming requests that can not be handled
624 Requests in queue for filter frontend_net are removed if client
625 closes connection for the session and request is not yet handled.
627 sru_z3950: serialize requests. This is to ensure that pipelined
628 HTTP requests are handled properly.
630 --- 1.3.28 2012/04/04
632 New class, wrbuf, that wraps YAZ' WRBUF.
634 --- 1.3.27 2012/03/30
636 Metaproxy daemon is now running as user "metaproxy". This user is
637 managed by package maintainer scripts. The user information is stored
638 in /etc/metaproxy/metaproxy.user .
640 --- 1.3.26 2012/03/20
642 New filter, sort, that allows sorting of XML records via Z39.50
645 Filter record_transform: USEMarcon support. For example:
646 <retrieval syntax="usmarc">
647 <backend syntax="unimarc" name="F">
648 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
652 Filter multi: empty route pattern uses route as default.
654 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
655 may use the shorter notation
656 <target route="z3950.indexdata.com"/>
658 Filter query_rewrite: use config path to locate XSLT.
660 Filter frontend_net: log statistics.
661 If a custom message element in frontend_net configuration it makes
662 the frontend_net filter produce a log entry whenever an operation
663 is completed. The log is always written using yaz_log with the
664 custom message given, the package ID (session ID) , the time
665 the operation has been active (end-to-end) , the threads currently
666 active/total and the size of the request input/output queues.
668 query_rewrite: charset conversion of query terms.
669 This is an optional feature. Enabled by element <charset> in
670 configuration with attribute 'from' and 'to' that specifies
671 from/to encodings. The default 'from' encoding is UTF-8.
673 Filter record_transform: honor piggyback searches.
675 Filter zoom: re-connect when database is reused.
676 Re-connect is necessary if a connection is lost or a timeout occurs.
677 If not, we'll be seeing zero hits, when we shouldn't.
679 --- 1.3.25 2012/02/29
681 zoom: Change scheme for dealing with content proxy URLs. The module
682 now has its own common XSL transform that is enabled by record_xsl
683 attribute in the configuration. This XSL gets parameter cproxyhost
684 that holds the host for the content proxy session . The genearted-url
685 is created only if urlRecipe is enabled. In previous version default
686 value of urlRecipe was ${md-electronic-url}; it is now empty and
687 disabled by default. Also generated-url no longer includes the content
688 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
691 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
692 connections. Default value is 40 (seconds).
694 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
695 "Malformed query" for syntax errors and related ones; throw
696 Bib-1: 3 "Unsupported search" for everything else. Details from
697 the CCL parser is provided as additional-info.
699 multi: new setting hideerrors that makes multi only relay diagnostics
700 to a client if all backends fail.
702 --- 1.3.24 2012/02/23
704 zoom: empty ccl_map field-mappings disables CCL map.
706 zoom: fix Explain search that could return error if session was
709 --- 1.3.23 2012/02/10
711 zoom: returns Explain records for database IR-Explain---1. The
712 target profile records are converted to Explain records via XSLT.
714 session_shared: make error recovery configurable. Whether a search
715 is restarted on errors or not, is configurable by attribute "restart"
716 in element "resultset" in configuration.
718 session_shared: only relay init for first request. session_shared, for
719 each backend class, now only relays first init request (rather than all).
720 The module only needs to save init response info once. This avoids the
721 need to check for session max.
723 --- 1.3.22 2012/02/02
725 zoom: fix memory leaks.
727 session_shared: maximum number of sessons is configurable. Default
728 value is 100. Result-sets for backends without named result sets are
729 only re-used if databases is identical for a search. This is under the
730 assumption that performance may suffer for those backends when
731 changing the database for each search.
733 multi: combines diagnostics from all backends. All diagnostics from
734 backends are combined into multiple non-surrogate diagnostics; rather
735 than just one diagnostic from first backend.
737 --- 1.3.21 2011/12/27
739 zoom: relay realm to cproxy parameter file.
741 Configuration: Allow filter collection element inside route. This
742 makes it possible to include multiple filters at once.
744 zoom: nocproxy also disables urlRecipe.
746 --- 1.3.20 2011/12/21
748 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
749 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
750 90: "Unsupported direction value".
752 zoom: honor database argument nocproxy. This disables creating a content
753 connector session (for non-CF targets, usually) and also relays nocproxy
754 as database argument to a CF target.
756 --- 1.3.19 2011/12/16
758 zoom: Multiple proxy hosts may be given for proxy rich database
759 parameter. List is comma separated.
761 http_file: decodes URI paths properly. Does not return 404: not found
762 if no prefix are matches. Instead packages are passed on.
764 --- 1.3.18 2011/12/08
766 zoom: content-{user,password,proxy} are passed on to content proxy
767 system and takes precedence over user,password,proxy .
769 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
770 with a log element including log material from children filters. At
771 this point, only the zoom filter uses this log facility. It will
772 eventually be used by other filters as well. In particular it might be
773 useful for this feature to track all filters in used during a search.
775 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
776 and queries as they are manipulated are logged.
778 zoom: extend addinfo with native diagnostics. Diagnostics as received
779 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
780 diagnostics. This indicates both a backend diagnostic and the original
783 zoom: default urlRecipe value is ${md-electronic-url}
785 zoom: target profile setting sruVersion is recognized.
787 --- 1.3.17 2011/11/17
789 zoom: log target profile record fetched (AKA Torus).
791 --- 1.3.16 2011/11/17
793 Change target profile parameter CfSubDb to CfSubDB.
795 --- 1.3.15 2011/11/12
797 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
798 makes sense to the zoom module itself).
800 --- 1.3.14 2011/11/11
802 zoom: realm may be given as part of database.
804 --- 1.3.13 2011/10/26
806 Fix Origin class assigment method; was removd by mistake in 1.3.12.
808 --- 1.3.12 2011/10/26
810 zoom: database args x-name=value are passed through to backend database.
812 SRU filter: user may specify session ID that is passed to log entries
813 that follows. It is specified by using x-session-id in the SRU arguments.
815 zoom: fix null pointer reference which would occur for bad url parameter
816 inside "torus" or if url was not given.
818 --- 1.3.11 2011/09/09
819 Fix bug in filter session_shared where sessions would not expire
820 properly (session ttl). This in turn could make the target close the
821 connection before expected and session_shared would return diagnostic
822 2: system temporarily available.
824 --- 1.3.10 2011/09/09
826 zoom: new target profile setting: sortmap_field. If sortmap_field is given
827 the field is mapped to the value for the sortmap. Values not matching
828 sortmap_field are passed verbatim.
830 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
831 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
832 depending on whether RPN or CQL is actually sent to the target.
836 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
838 zoom: For content proxy authentication is stored in param name
839 "auth", instead of "authentication".
843 zoom: relay schema in SRU mode. Previously recordSchema was not affected
848 zoom: new target profile element literalTransform that holds XSLT
849 (encoded as string) for target. Only if present and non-zero length it is
850 considered present. This takes precedence over transform.
852 Don't rely on trang anymore for Git checkout builds. Configuration in etc
853 will only be properly validated if trang is available. From now on only
854 relax NC files are bundled with the source dist.
856 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
857 component was not detected when it should be.
861 z3950_client: mark non-surrogate diagnostics from backend.
863 zoom: a proxy may be specified for HTTP fetch of target profiles.
867 Honor piggyback. Makes some SRU targets behave that insist on
868 maximumRecords > 0, but also increases performance.
872 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
873 file was not update for libdir/metaproxy4 in version 1.3.2.
877 Change location of Metaproxy modules from libdir/metaproxy to
878 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
879 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
881 New facility to dump APDUs from zoom filter. Enabled by
882 <log apdu="true"/> in the zoom filter configuation.
884 zoom filter bug fix: SRU diagnostics received from backend was
885 not properly converted to Bib-1 diagnostics.
887 Package metaproxy depends on libmetaproxy4, same version.
891 zoom: fix a bug WRT passing authentication parameters to backends.
895 Fixes for windows Makefile.
897 --- 1.2.10 2011/07/25
899 Change major version of metaproxy library from 3 to 4. This in turn
900 makes new package names for Debian and RPM.
904 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
907 zoom: configurable element sets for record transforms.
909 zoom: the target profile based transform is specified by element_transform
910 in element torus of of the ZOOM filter configuration ; default value
911 is "pz2". Target profile based retrieval is specified by element_raw
912 in configuration. It will perform same steps, but omit the XSL transform.
913 Default value is "raw".
915 zoom: element set is omitted if not set in profile. But only if pz2
916 transform is in effect. Previously the default element set was to "F".
918 zoom: For non-CF targets database arguments are parsed. User may supply
919 db,user=myuser&password=mypass for non-CF targets. These values override
920 what's given the authentication from the target profile.
922 session_shared: fix reference to freed memory. Would occur if a search
923 response had non-surrogate diagnostics.
927 Route may be given for each port in frontend_net.
931 Documentation for zoom filter. Local target profiles may be specified.
933 Fixes for zoom filter.
937 First version with zoom filter.
941 Filter z3950_client may be configured to always send a close APDU
942 to backend target when connection/session is closed. This will only
943 happen if close APDU is not already sent. Enabled by configuration
944 for z3950_client (force_close).
946 Filter virt_db and multi: relay close APDU.
948 Filter virt_db and multi: relay init size parameters
949 preferredMessageSize and maximumRecordSize.
951 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
955 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
957 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
958 as determined by configure.
960 RPM: Release includes 'indexdata' name. Use indexdata in release name so
961 this package can be distinguished from other vendors.
965 Fix filter multi: relay idAuthentication parameters.
969 Add metaproxy-config for returning compiler flags, libraries.
973 Fix --with-boost=PREFIX .
977 session_shared: fix use of maintenance thread.
979 Introduce 'start' method for filters and routers. It gets called after
980 configure and after fork, but before processing. This changes API -
981 from libmetaproxy2 to libmetaproxy3.
985 session_shared: ensure backend session is closed if init rejected
988 z3950_client: fix NULL ptr reference that could occur if two clients
989 connected concurrently and if max-sockets was in effect.
993 Fix bug 3497 - Metaproxy unstable while stopping.
995 Fix bug 3495 - SEGV in SRU filter.
999 Filter multi throws diagnostic 'Present Out of Range' when
1000 appropriate - rather than returning 0 records.
1002 Filter virt_db: fix bad result reuse. Could happen if a result
1003 was overriden and a backend did not supported named result sets.
1005 --- 1.1.4 2010/05/11
1007 Filter log: category access logs diagnostics even if searchStatus
1008 or presentStatus is 'success'.
1010 --- 1.1.3 2010/04/21
1012 The SRU to Z39.50 filter does repeated Z39.50 present requests
1013 to fetch all records. Needed when a Z39.50 server returns partial
1014 results (due to message size limits).
1016 --- 1.1.2 2010/03/18
1018 Metaproxy now kills all child processes that are spawned by
1019 modules (in case of fork, exec).
1021 --- 1.1.1 2010/01/28
1023 Debian package now installs /etc/metaproxy/metaproxy.xml which
1024 includes all XML files /etc/metaproxy/filters-enabled .
1025 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1027 --- 1.1.0 2010/01/20
1029 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1030 development package to facilitate 3rd party Metaproxy modules.
1032 --- 1.0.23 2010/01/04
1034 Filter virt_db: Close backend filter session when Init rejected is received
1035 from it (in which case it's not really closed yet). This will ensure we don't
1036 run out of resources such as FDs in this case.
1038 sru_z3950 filter: Accept any database (including those not listed).
1040 --- 1.0.22 2009/12/03
1042 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1043 later which means YAZ 3.0.47 or later.
1045 --- 1.0.20 2009/11/19
1047 For filter virt_db, the database is a glob pattern and the virtual
1048 database sections are consulted in the order given.
1050 --- 1.0.19 2009/07/08
1052 For filter multi, the target (for routing) may be given as a glob-pattern.
1054 More documentation for filters virt_db and multi.
1056 Update schema to allow for no database in sru_z3950 filter.
1058 --- 1.0.18 2009/06/30
1060 Added limit filter to put sleep (penalty) for heavy use.
1062 Filter frontend_net may be configured to limit the number of new connections
1063 from same IP to some value (connect-max).
1065 Fixed the load_balance filter.
1067 --- 1.0.17 2009/06/16
1069 Fix path for metaproxy executable for Debian init.d script.
1071 --- 1.0.16 2009/06/10
1073 SRU to Z39.50 filter honors x-username and x-password. If only
1074 x-username is given that translates to open authentication (Z39.50v2). If
1075 both x-username and x-password is present that translates to idPass
1076 authentication (Z39.50v3).
1078 New facility to change current working directory (-w).
1080 Update to upstream skeleton of init.d script. Should fix bug #2619.
1082 Filter session_shared now caches records (used to only cache connections
1085 Filter session_shared now invalidates a Z39.50 session if a server
1086 returns -1 hits. This facility was also part of yazproxy and gets around
1087 a bug in Voyager-based Z39.50 servers.
1089 --- 1.0.15 2008/11/18
1091 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1093 --- 1.0.14 2008/06/09
1095 Fixed the value of SRU record schema in searchRetrieve response. It was set
1096 to a fixed value of "dc" before.
1098 Serialize identical SRU requests. This is useful if HTTP client software
1099 fires identical requests against metaproxy.
1101 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1102 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1103 avoid static configuration. This facility is handled by the sru_z3950 module
1104 and the z3950_client module.
1106 Allow maximum number of sockets to be used for a Z39.50 client by the
1107 use of SRU extra parameter x-max-sockets. This facility is handled by the
1108 sru_z3950 module and the z3950_client module.
1110 --- 1.0.13.1 2008/02/29
1112 Simplified check for Boost libraries.
1114 --- 1.0.13 2008/02/29
1116 First Debian package.
1118 The sru_z9350 filter now recognizes SRU parameter z-target as being
1119 a ZURL of the form host/database .
1121 Mergetype may be specified for filter 'multi'.
1123 --- 1.0.12 2007/09/19
1125 Fixed problem in Makefile WRT library specifictions. This could produce
1126 linker errors (when they should not happen).
1128 Fixed bug #1341: MetaProxy returning different results. Problem was that
1129 fix-up of record database did not normalize the database name.
1131 Documentation updates for Windows compilation.
1133 --- 1.0.11 2007/06/14
1135 Fixed problem with logfile being truncated.
1137 --- 1.0.10 2007/05/23
1139 Fixed bug #1136: Access rights not enforced.
1141 Extension for log module. The log category 'access' logs more details.
1142 New category 'user-access' added which is simlar to 'access' but adds
1143 the Z39.50 user as for all entries in a session.
1147 Added support for configurable default/force target/vhost for module Z39.50
1150 --- 1.0.8 2007/01/25
1152 Implemented filter, session_shared, which optimizes usage of Z39.50
1153 sessions and result sets.
1155 New filter, record_transform, which converts MARC/XML records.
1157 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1159 New filter, load_balance, in development.
1161 New filter, zeerex_xplain.
1163 XML framework for config files started.
1165 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1166 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1167 XML config files are checked against RNG and XML Schema's.
1169 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1170 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1171 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1172 explain record to YAZ CQL-to-PQF text config file.
1174 --- 1.0.7 2006/11/07
1176 Added 'timeout' setting for filter frontend_net which specifies the number
1177 of seconds a session is idle before it is closed. Default timeout is
1180 --- 1.0.6 2006/07/07
1182 Database name in records returned set for virt_db/multi filters.
1184 Filter session_shared now functional.
1186 Log filter can be configured to write to a given file using 'filename'
1187 element. Also information category can be specified with 'category'. If
1188 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1191 --- 1.0.5 2006/05/16
1193 Fixed compilation on Windows.
1195 --- 1.0.4 2006/05/16
1197 Added documentation for the hidenavailable option for the multi filter.
1199 --- 1.0.3 2006/05/16
1201 Fixed bug #573: Hide errors for individual servers. If the element
1202 'hideunavailable' is given in the configuration, individual servers
1203 being unavailable are hidden (unless all are unavailable).
1205 Fixed bug #574: Database names are recognised case-sensitively.
1207 Fixed bug #567: Fix up database name in Name-Plus-Record.
1209 Fixed bug #568: Update win/makefile for VS 2005.
1211 Fixed bug #569: Some options throws unknown exception.
1213 --- 1.0.2 2006/04/28
1215 More information about virtual hosts. The 'etc' directory is part of the
1218 --- 1.0.1 2006/04/27
1220 Build instructions for Windows. NMake makefile part of distribution tar.
1222 --- 1.0.0 2006/04/24
1226 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1227 log, multi, query_rewrite, template, virt_db, z3950_client.
1229 Filters in development: session_shared.
1231 Pseudo-filters: template, dl
