3 zoom: allow / in user and password db args MP-592
7 Log rotate no longer reloads configuration - instead Metaproxy just
8 re-opens log files when SIGHUP is received. MP-485
10 Debian : init.d metaproxy reload should check configuration MP-591
12 Fix Metaproxy stops logging after check config failed MP-590
16 Fix double free in log filter (with incorrect config) MP-589
18 zoom: Add allow_ip feature - fixes MP-588
19 Allow a list of IPs to be given separated by blanks
20 <allow auth_url="http://mkc-admin.indexdata.com/..."
21 allow_ip="127.0.0.1 ::1" .. >
23 cql2pqf.txt: Maps dc.subject to Bib-1 21 rather than 47
25 zoom: fix CS write-check
29 zoom: handle contentAuthentication MP-587
33 Destroy router and filters in parent process MP-584
35 Update NMAKE makefile to use Visual Studio 2013 along with Boost 1.57,
36 ICU 54.1, Libxml2 2.9.2, Libxslt 1.1.28.
40 Use YAZ backtrace facility MP-582
42 Fix libmetaproxy-dev depends on libgnutls-dev - MP-580
43 libgnutls-dev is unavailable on jessie.
45 Update template filter to avoid Pimpl MP-579
47 cgi: POSTed content - part of MP-562
49 Fix filter cgi does not relay session close MP-577
53 Add support for binding outgoing IP for http_client and z3950_client
54 This is enabled by bind_host setting. MP-575
58 z3950_client: allows negotiation charset to be set MP-574
60 cgi: more functional but no support for POSTed content yet (part of MP-564)
64 http_file: add include of sys/stat.h fixes MP-576
66 Fix documentation about SRU client support MP-572
68 Initialize Libxml2 - for threaded operation MP-571
72 On SIGTERM shut down connection+listening sockets MP-568
73 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
77 zoom: make retry on failure configurable MP-565
78 The default and existing behavior is that backend failures (any
79 diagnostic) makes the module re-search once. The behavior may
80 be changed by db parameter 'retry'. If given value '0' disables
81 retry and '1' enables it. If not given, the Torus record may
82 specify with element retryOnFailure (value '0'/'1').
86 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
87 instead of just a child process. Extremely rare in real life, hit me with
88 CF stress testing. MP-559.
92 http_file: passthru option MP-557
93 New facility for http_file to passthru - even if an area is matched. The
94 default behavior (passthru=false) is to return 404: Not found. With
95 passthru=false, next filter is consulted.
99 Fix ref to freed memory in log filter 1line - MP-556
101 echoedSearchRetrieveRequest support MP-555
105 zoom: allow hostname to be given for ipauth MP-552
106 The Torus setting for that is called auth_hostname.
110 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
114 session_shared: close in ~BackendInstance MP-549
115 This fixes a serious issue where some MP would leak sockets.
117 session_shared: mutex lock in BackendClass::release_backend MP-550
118 Fixes a SEGV that could occur (in rare cases).
122 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
124 zoom: fix invalid present response in some cases MP-546
126 zoom: Relay Torus HTTP error message
130 Check for proper limits before using RecordCache functions MP-544
134 Build packages for Ubuntu Trusty Tahr 14.04 LTS
136 sort: crash / invalid_read in filter sort MP-541
138 sru_z3950: facet should be stored in additionalSearchInfo MP-533
140 doc: fix missing man pages MP-542
142 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
144 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
148 sru_z3950: fix facet response (memory corruption) MP-532
150 log: fix crash idPass user is omitted MP-530
154 query_rewrite: pass-thru non Type-1 queries MP-527
156 metaproxy stop (SIGTERM) kills all child processes spanwed by
157 filter (if any) before invoking filter destructors. MP-525
161 http_file: only supports HTTP GET MP-523
163 session_shared: shut down expire thread in destructor
164 This ensures that expire thread is not running after destruction
165 and does bad memory references, etc.
167 frontend_net: fix segfault on startup MP-524
168 Would happen if MP was listening on multiple ports and one
169 of the ports was already in use (and MP would exit).
171 frontend_net: fix memory leak MP-521
172 This leak would occur if all sessions were in use and the input
173 queue was cleared when a client would close connection (socket).
175 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
179 http_rewrite: use local skiplist; fixes memory corruption. MP-520
181 http_client: x-forwarded-for controls X-Forwarded-For presence
182 If x-forwarded-for setting (boolean) is enabled, http_client will
183 generate an X-Forwarded-For header entry which includes existing
184 X-Forwarded-For (if any) and current peer address (immediate client
185 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
186 will not be generated.
188 z3950_client: client_ip controls client-IP presence
189 If client_ip setting (boolean) is enabled, z3950_client will
190 generate a client_ip OID as part of init request which includes
191 previous client_ip (if any) and current peer address (immediate
192 client of Metaproxy). By default client_ip is disabled and client_ip
193 will not be generated.
195 HTTP X-Forwarded-For/Z39.50 Client-IP support
196 virt_db, multi: relays Z39.50 client-IP.
197 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
198 zoom: uses Client-IP or origin address (prefer Client-IP).
199 frontend_net: Strips tcp: from peer address (so that it is no longer
200 printed and stripped in zoom filter).
201 z3950_client: builds client-IP list - combining immediate peer address
202 as returned by COMSTACK and existing client-IP list (if avaiable).
203 The Origin only printes first X-Forwarded address.
207 Log when SIG{TERM,USR1} is received ASAP MP-513
208 Do it in frontend_net event loop rather than in place for metaproxy
209 main, which only exits when all sessions are terminated for SIGUSR1
212 metaproxy-config: quote some RHS values (that might include blanks)
214 Fix leak in sru_z3950 filter - when explain is returned MP-511
216 Allow stylesheet to be given for sru_z3950 filter MP-510
217 This is based on a patch by Sven Porst and the functionality
218 of the YAZ Generic Frontend Server.
220 Allow base attribute in configuration file tags - the attributes are
221 inserted by XInclude usage as mentioned on
222 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
223 and noted in a gist: https://gist.github.com/3551094
225 Package metaproxy provides virtual package metaproxy6 MP-508
226 This allows module packages to depend on a metaproxy server
229 Filter destructors called upon daemon termination MP-505
230 When metaproxy daemon receives SIGTERM the stop method of each filter
231 is called. The stop method existed before, but did not take any
232 arguements (void).. The frontend_net filter can now distinguish
233 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
234 (stop immediately). Note that this changes the API+ABI of Metaproxy
237 zoom: sync up with Pazpar2 WRT authentication handling MP-492
239 Router: use shared_ptr rather than naked one - to avoid leak if an
240 exception is thrown in configure.
244 zoom: Add nocproxy=1 for contentConnector sessions MP-501
246 Doc: mention proper versions; fix link to Boost win binaries.
248 Windows: update for Boost 1.55
250 Windows: avoid warning when using boost::split. Done by defining
251 _SCL_SECURE_NO_WARNINGS for Visual Studio.
253 Fix LSB conformance for /etc/init.d/metaproxy MP-500
254 Debian: add support for /etc/init.d/metaproxy status
256 sort: Add const to Record less than operator in order to compile on
261 session_shared: fix element-set handling in record caching. MP-499
263 document http_rewrite. MP-468
265 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
266 respects the header (which will normally come from the cproxy filter)
270 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
271 RPM was unsable in version 1.4.0.
273 Remove log message about "backend classes". Appeared in version 1.4.0.
277 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
278 with older version from source, but packages now use YAZ 5 that supports
281 sru_z3950: Fix SEGV for decoding invalid SRU requests
282 Incorrect reference to union (was explain response rather than
285 session_shared: match additionalSearchInfo (includes facets). In
286 layman's terms means that means that facets are properly handled
287 by this filter. Eg a change in requested facets will issue new
288 search and facets from exisiting result set are cached.
290 --- 1.3.62 2013/09/11
292 http_rewrite: better handling of <script> content in HTML parser. MP-486
294 http_rewrite: fix threading issue with regex. MP-482
296 bounce: don't use strdup for fixed length content. Error occurred in echo
299 session_shared: expire backend class when no instances left. This
300 means memory clean up, but not really a leak fix.
302 virt_db: fix leak for naked ptr.
304 cql_rpn: use config relative path for cql2rpn file. MP-481
306 Updates for upcoming YAZ 5.
308 --- 1.3.61 2013/08/29
310 New configuration directories ports.d/routes.d for metaproxy
311 configuration. This allows 3rd party packages to install config
312 for ports and new routes. MP-477
314 --- 1.3.60 2013/08/21
316 Fix metaproxy-config --libs to return non-mt over mt libs.
317 The -mt versions do not exist as shared objects and cause
318 linker errors for applications linking with Metaproxy.
319 Problem present in versions 1.3.56 - 1.3.59. MP-475
321 HTML: clean up char checks. Add ptr to HTML parse spec
323 HTML parser stops eating tag when <-char is met MP-473
325 rewrite: do not even compare content types, if we don't have any
326 the regex_match caused a segfault if we had no content-type in the
329 rewrite: within header=... matches only the header value
330 Used to match the whole header line, but we need to use
331 ^$ anchoring for host-relative regexps, and they need to
332 anchor at the ends of the value. MP-470.
334 rewrite: Ruleset functional MP-469
336 --- 1.3.59 2013/07/12
338 session_shared: negotiate init sz parameters.
339 By default, session_shared will honor the paramters given by client.
340 An alternative, but not implemented, algorithm would be to only
341 re-use sessions with same sz parameters. This however, could reduce
342 re-use of sessions a lot. Hence this, simple algorithm instead. The
343 negotiation to a maximum sz values can be enabled by using
344 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
345 in configuration. This will make session_shared send those values
346 to backends and use returned init values in negotaition to
347 client before session_shared.
349 session_shared: resolve result-set references.
350 The reference is substitued with the query for old set if database
351 match and query type is Type-1. If not the reference will issue a
354 sort filter: relays RecordComposition including elementSet in use for
357 http_client: better diagnostics
359 http_client: disables HTTP redirect handling by default.
360 It can be configured with max-redirects in configuration.
362 --- 1.3.58 2013/06/12
364 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
366 --- 1.3.57 2013/06/12
368 Make RouterChain and RouterXML part of public API (libmetaproxy).
370 http_client: honor X-Metaproxy-Proxy as an alternative to
371 the "proxy" configuration. Allows proxy to be set per HTTP request.
373 sru_z3950: For SRU requests recognize x-client prefixes as a way
374 to ingest "database parameters".. The suffix of x-client- serves
375 as database argument name. Multiple may be given. For example:
376 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
377 is turned into Z39.50 database
380 --- 1.3.56 2013/05/27
382 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
384 New filter sd_remove, which replaces surrogate diagnostics with
385 SUTRS records. This filter tries to deal with clients that breaks
386 when receiving surrogate diagnostics.
388 new filter http_client. Same role as z3950_client, but just for
389 HTTP. Allows Metaproxy to operate as a HTTP proxy.
391 New filter http_rewrite1, which serves as purpose on how to rewrite
392 HTTP content with Metaproxy.
394 Use libboost-system if available, because newer versions of libboost-threads
395 requires libboost-system.
397 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
400 --- 1.3.55 2013/04/10
402 zoom: Torus setting: authenticationMode which may hold values "basic"
405 --- 1.3.54 2013/03/27
407 configure: check for Libxslt support in YAZ and rely on definitions
408 from yaz-config, rather than doing own xslt/xml2 checks.
410 Allow timestamp format for log lines to be given with option -m
411 for metaproxy. Similar to yaz-ztest/GFS option -m.
413 Document log category 'line' for log filter.
415 Solr configuration example in etc/config-solr.xml
417 multi: do not mess with request package. For scan and search,
418 database-names were modified and the request package was left with
419 dangling pointers that caused a log filter to fail (request package
420 inspected after multi was invoked).
422 Documentation: fix id of metaproxy-config ref .
424 Documentation: update for USEMARCON support.
426 --- 1.3.53 2013/01/31
428 record_transform: allow OPACXML to OPAC conversion
430 zoom: document content-proxy
432 zoom: document db parm content-{user,password}, torus_url. Also
433 <torus auth_url="..> which makes zoom operate in authenticated mode
436 --- 1.3.52 2012/11/30
438 zoom: fix http://-check. SRU search broken in 1.3.51.
440 --- 1.3.51 2012/11/15
442 zoom: only append http:// for SRU if not already given . Makes it
443 possible to use https-URLs.
445 Use yazpp 1.4 or later due to new ABI.
447 frontend_net: allow max package size to be specified. Controlled by
448 attribute 'max_recv_bytes' of element 'port'.
450 --- 1.3.50 2012/10/29
452 For most generated diagnostics by filters, typically temporary
453 system error, augment addinfo message with filter name.
455 Add support for CentOS 6 packages.
457 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
459 Add man page for metaproxy-config.
461 --- 1.3.49 2012/10/18
463 zoom: new config element passthru. This defines an element set that is
464 passed verbatim to the backend in pz2 mode.
466 auth_simple: allow both idPass and open auth. Also fix SEGV that could
469 --- 1.3.48 2012/10/08
471 z3950_client: fix string handling for init diagnostics in the case where
474 query_rewrite: no charset conversion for error queries. Avoid performing
475 charset conversion for query conversion errors. The resulting Type-1
476 query is invalid in this case.
478 --- 1.3.47 2012/10/04
480 For graceful stop (SIGUSR1), metaproxy will kill children processes.
482 Log when metaproxy is invoked in test mode (-t).
484 Log PID for each log message.
486 multi: combine both NSDs and multiple NSDs into one (diagnostics).
488 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
489 a (backend=target) is appended for each diagnostic so that can be
490 determined the origin of error.
492 multi: hideerrors also in use for present response.
494 Solr example in zoom man page.
496 Fix typo in query_rewrite config example.
498 Log at least first non surrogate diagnostic. Instead of
499 "Z_Records_multipleNSD"
501 multi: Fix check for opt Records in present response. A SEGV could occur
502 if a target did not return records and no diagnostics.
504 --- 1.3.46 2012/09/24
506 Yet another fix for graceful stop.
508 --- 1.3.45 2012/09/12
510 sru_z3950: relay surrogate diagnostics.
512 --- 1.3.44 2012/09/10
514 zoom: Honor extraArgs, strip # in zurl.
516 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
518 zoom: url_recipe allow %{var[reg]} substitutions.
519 It's like ${var[reg]} but does URI component encoding as well.
521 --- 1.3.43 2012/08/22
523 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
524 non-keepalive HTTP sessions.
526 http_file: allow zero size files (bug fix)
528 Fix zoom schema: auth_url is optional
530 --- 1.3.42 2012/08/20
532 zoom: fix un-init memory (could result in SEGV at session close)
534 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
535 and may be used in filters as usual.
537 zoom: authentication via Torus lookup
538 Enabled by new configuration setting: auth_url . If this is defined,
539 the zoom module will contact Torus for auth/IP lookup and that will
540 define realm to be used in session.
542 --- 1.3.41 2012/08/10
544 virt_db: Fix database name - first character we removed by mistake.
545 Bug introduced in 1.3.40.
547 --- 1.3.40 2012/08/06
549 virt_db: Don't use "unix path" as database for Unix sockets.
551 --- 1.3.39 2012/08/02
553 z3950_client: Don't tamper with / in zurl - fixes problems
554 using Unix sockets for backends.
556 session_shared: fix integer overflow problem with hit count.
558 session_shared: avoid long usage of cached queries.
560 zoom: New database argument , torus_url to set URL of Torus
561 record to be fetched.
563 --- 1.3.38 2012/07/04
565 Fixes for 'metaproxy reload' for RPM/Debian packages.
567 zoom: Allow rpn2cql conversion to be augmented with a properties file.
568 Element rpn2cql can be specified per-target for the zoom filter.
570 log: New category "line" which is a single-line log message with
571 most important parts of a HTTP/Z39.50 request/response.
573 --- 1.3.37 2012/06/01
575 frontend_net: add facility to report live statistics about response
576 times and current thread usage. The report is an XML document
577 and is triggered for a specific URL path. This is set by <stat-req>
578 in the configuration of frontend_net. By default this report is
579 disabled (same as empty value for <stat-req>).
581 Fix reload problem in init.d script for RPM/Debian.
582 The '/etc/init.d/metaproxy reload' in some cases would stop but not
583 start metaproxy - effectively stopping the service.
585 Don't display start log message when config testing (-t).
587 zoom: avoid CCL message limit of 1K in ZOOM filter.
589 --- 1.3.36 2012/05/10
591 metaproxy init script reacts to reload which does graceful stop +
592 start and is used by logrorate script.
594 --- 1.3.35 2012/05/09
596 Fixes for Windows compilation.
598 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
599 existing sessions running but terminate the monitor process that is
600 used in keepalive mode.
602 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
603 before. Consistent with 'metaproxy stop' message.
605 zoom: document zoom's proxy_timeout
607 z3950_client: fixup addinfo for init response
609 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
610 "Access to specified database denied" is returned, but only if init
611 response from backend does not carry diagnostics already.
613 multi: relays user info for first rejected target. The other-information
614 field for init response for first rejected target is in common init
615 response. This ensures that some backend init diagnostics are returned to
618 --- 1.3.34 2012/04/25
620 frontend_log: extend logging (when message is given in config).
622 --- 1.3.33 2012/04/25
624 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
626 --- 1.3.32 2012/04/24
628 sru_z3950 filter passes through incoming Z39.50 requests again. Was
629 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
631 --- 1.3.31 2012/04/24
633 zoom: fixes for retry/proxy failover logic. More logging.
635 --- 1.3.30 2012/04/23
637 zoom: return addinfo="proxy failure" for proxy failures. This also
638 changes the scheme for dealing with proxies a bit. zoom now always
639 do proxy check, even if there's no failover. Fortunately, that's not
642 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
643 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
644 generic. We don't know why the init would fail; IP, user, block IP, etc.
645 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
647 zoom: guess if invalid SRU response was an auth failure
649 session_shared: disable session retry by default . Can be enabled by
650 restart="true" in resultset section.
652 --- 1.3.29 2012/04/18
654 zoom: may read cf-proxy's config settings.
655 This reduces manual configuration of the content proxy server host.
656 The ZOOM module will use the old style session.proxyhost if "server"
657 is given (deprecated) and use the new style proxyhost/session if
658 "config_file" is in use.
660 frontend_net: remove incoming requests that can not be handled
661 Requests in queue for filter frontend_net are removed if client
662 closes connection for the session and request is not yet handled.
664 sru_z3950: serialize requests. This is to ensure that pipelined
665 HTTP requests are handled properly.
667 --- 1.3.28 2012/04/04
669 New class, wrbuf, that wraps YAZ' WRBUF.
671 --- 1.3.27 2012/03/30
673 Metaproxy daemon is now running as user "metaproxy". This user is
674 managed by package maintainer scripts. The user information is stored
675 in /etc/metaproxy/metaproxy.user .
677 --- 1.3.26 2012/03/20
679 New filter, sort, that allows sorting of XML records via Z39.50
682 Filter record_transform: USEMarcon support. For example:
683 <retrieval syntax="usmarc">
684 <backend syntax="unimarc" name="F">
685 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
689 Filter multi: empty route pattern uses route as default.
691 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
692 may use the shorter notation
693 <target route="z3950.indexdata.com"/>
695 Filter query_rewrite: use config path to locate XSLT.
697 Filter frontend_net: log statistics.
698 If a custom message element in frontend_net configuration it makes
699 the frontend_net filter produce a log entry whenever an operation
700 is completed. The log is always written using yaz_log with the
701 custom message given, the package ID (session ID) , the time
702 the operation has been active (end-to-end) , the threads currently
703 active/total and the size of the request input/output queues.
705 query_rewrite: charset conversion of query terms.
706 This is an optional feature. Enabled by element <charset> in
707 configuration with attribute 'from' and 'to' that specifies
708 from/to encodings. The default 'from' encoding is UTF-8.
710 Filter record_transform: honor piggyback searches.
712 Filter zoom: re-connect when database is reused.
713 Re-connect is necessary if a connection is lost or a timeout occurs.
714 If not, we'll be seeing zero hits, when we shouldn't.
716 --- 1.3.25 2012/02/29
718 zoom: Change scheme for dealing with content proxy URLs. The module
719 now has its own common XSL transform that is enabled by record_xsl
720 attribute in the configuration. This XSL gets parameter cproxyhost
721 that holds the host for the content proxy session . The genearted-url
722 is created only if urlRecipe is enabled. In previous version default
723 value of urlRecipe was ${md-electronic-url}; it is now empty and
724 disabled by default. Also generated-url no longer includes the content
725 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
728 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
729 connections. Default value is 40 (seconds).
731 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
732 "Malformed query" for syntax errors and related ones; throw
733 Bib-1: 3 "Unsupported search" for everything else. Details from
734 the CCL parser is provided as additional-info.
736 multi: new setting hideerrors that makes multi only relay diagnostics
737 to a client if all backends fail.
739 --- 1.3.24 2012/02/23
741 zoom: empty ccl_map field-mappings disables CCL map.
743 zoom: fix Explain search that could return error if session was
746 --- 1.3.23 2012/02/10
748 zoom: returns Explain records for database IR-Explain---1. The
749 target profile records are converted to Explain records via XSLT.
751 session_shared: make error recovery configurable. Whether a search
752 is restarted on errors or not, is configurable by attribute "restart"
753 in element "resultset" in configuration.
755 session_shared: only relay init for first request. session_shared, for
756 each backend class, now only relays first init request (rather than all).
757 The module only needs to save init response info once. This avoids the
758 need to check for session max.
760 --- 1.3.22 2012/02/02
762 zoom: fix memory leaks.
764 session_shared: maximum number of sessons is configurable. Default
765 value is 100. Result-sets for backends without named result sets are
766 only re-used if databases is identical for a search. This is under the
767 assumption that performance may suffer for those backends when
768 changing the database for each search.
770 multi: combines diagnostics from all backends. All diagnostics from
771 backends are combined into multiple non-surrogate diagnostics; rather
772 than just one diagnostic from first backend.
774 --- 1.3.21 2011/12/27
776 zoom: relay realm to cproxy parameter file.
778 Configuration: Allow filter collection element inside route. This
779 makes it possible to include multiple filters at once.
781 zoom: nocproxy also disables urlRecipe.
783 --- 1.3.20 2011/12/21
785 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
786 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
787 90: "Unsupported direction value".
789 zoom: honor database argument nocproxy. This disables creating a content
790 connector session (for non-CF targets, usually) and also relays nocproxy
791 as database argument to a CF target.
793 --- 1.3.19 2011/12/16
795 zoom: Multiple proxy hosts may be given for proxy rich database
796 parameter. List is comma separated.
798 http_file: decodes URI paths properly. Does not return 404: not found
799 if no prefix are matches. Instead packages are passed on.
801 --- 1.3.18 2011/12/08
803 zoom: content-{user,password,proxy} are passed on to content proxy
804 system and takes precedence over user,password,proxy .
806 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
807 with a log element including log material from children filters. At
808 this point, only the zoom filter uses this log facility. It will
809 eventually be used by other filters as well. In particular it might be
810 useful for this feature to track all filters in used during a search.
812 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
813 and queries as they are manipulated are logged.
815 zoom: extend addinfo with native diagnostics. Diagnostics as received
816 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
817 diagnostics. This indicates both a backend diagnostic and the original
820 zoom: default urlRecipe value is ${md-electronic-url}
822 zoom: target profile setting sruVersion is recognized.
824 --- 1.3.17 2011/11/17
826 zoom: log target profile record fetched (AKA Torus).
828 --- 1.3.16 2011/11/17
830 Change target profile parameter CfSubDb to CfSubDB.
832 --- 1.3.15 2011/11/12
834 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
835 makes sense to the zoom module itself).
837 --- 1.3.14 2011/11/11
839 zoom: realm may be given as part of database.
841 --- 1.3.13 2011/10/26
843 Fix Origin class assigment method; was removd by mistake in 1.3.12.
845 --- 1.3.12 2011/10/26
847 zoom: database args x-name=value are passed through to backend database.
849 SRU filter: user may specify session ID that is passed to log entries
850 that follows. It is specified by using x-session-id in the SRU arguments.
852 zoom: fix null pointer reference which would occur for bad url parameter
853 inside "torus" or if url was not given.
855 --- 1.3.11 2011/09/09
856 Fix bug in filter session_shared where sessions would not expire
857 properly (session ttl). This in turn could make the target close the
858 connection before expected and session_shared would return diagnostic
859 2: system temporarily available.
861 --- 1.3.10 2011/09/09
863 zoom: new target profile setting: sortmap_field. If sortmap_field is given
864 the field is mapped to the value for the sortmap. Values not matching
865 sortmap_field are passed verbatim.
867 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
868 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
869 depending on whether RPN or CQL is actually sent to the target.
873 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
875 zoom: For content proxy authentication is stored in param name
876 "auth", instead of "authentication".
880 zoom: relay schema in SRU mode. Previously recordSchema was not affected
885 zoom: new target profile element literalTransform that holds XSLT
886 (encoded as string) for target. Only if present and non-zero length it is
887 considered present. This takes precedence over transform.
889 Don't rely on trang anymore for Git checkout builds. Configuration in etc
890 will only be properly validated if trang is available. From now on only
891 relax NC files are bundled with the source dist.
893 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
894 component was not detected when it should be.
898 z3950_client: mark non-surrogate diagnostics from backend.
900 zoom: a proxy may be specified for HTTP fetch of target profiles.
904 Honor piggyback. Makes some SRU targets behave that insist on
905 maximumRecords > 0, but also increases performance.
909 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
910 file was not update for libdir/metaproxy4 in version 1.3.2.
914 Change location of Metaproxy modules from libdir/metaproxy to
915 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
916 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
918 New facility to dump APDUs from zoom filter. Enabled by
919 <log apdu="true"/> in the zoom filter configuation.
921 zoom filter bug fix: SRU diagnostics received from backend was
922 not properly converted to Bib-1 diagnostics.
924 Package metaproxy depends on libmetaproxy4, same version.
928 zoom: fix a bug WRT passing authentication parameters to backends.
932 Fixes for windows Makefile.
934 --- 1.2.10 2011/07/25
936 Change major version of metaproxy library from 3 to 4. This in turn
937 makes new package names for Debian and RPM.
941 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
944 zoom: configurable element sets for record transforms.
946 zoom: the target profile based transform is specified by element_transform
947 in element torus of of the ZOOM filter configuration ; default value
948 is "pz2". Target profile based retrieval is specified by element_raw
949 in configuration. It will perform same steps, but omit the XSL transform.
950 Default value is "raw".
952 zoom: element set is omitted if not set in profile. But only if pz2
953 transform is in effect. Previously the default element set was to "F".
955 zoom: For non-CF targets database arguments are parsed. User may supply
956 db,user=myuser&password=mypass for non-CF targets. These values override
957 what's given the authentication from the target profile.
959 session_shared: fix reference to freed memory. Would occur if a search
960 response had non-surrogate diagnostics.
964 Route may be given for each port in frontend_net.
968 Documentation for zoom filter. Local target profiles may be specified.
970 Fixes for zoom filter.
974 First version with zoom filter.
978 Filter z3950_client may be configured to always send a close APDU
979 to backend target when connection/session is closed. This will only
980 happen if close APDU is not already sent. Enabled by configuration
981 for z3950_client (force_close).
983 Filter virt_db and multi: relay close APDU.
985 Filter virt_db and multi: relay init size parameters
986 preferredMessageSize and maximumRecordSize.
988 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
992 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
994 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
995 as determined by configure.
997 RPM: Release includes 'indexdata' name. Use indexdata in release name so
998 this package can be distinguished from other vendors.
1000 --- 1.2.3 2010/10/04
1002 Fix filter multi: relay idAuthentication parameters.
1004 --- 1.2.2 2010/09/15
1006 Add metaproxy-config for returning compiler flags, libraries.
1008 --- 1.2.1 2010/08/18
1010 Fix --with-boost=PREFIX .
1012 --- 1.2.0 2010/07/09
1014 session_shared: fix use of maintenance thread.
1016 Introduce 'start' method for filters and routers. It gets called after
1017 configure and after fork, but before processing. This changes API -
1018 from libmetaproxy2 to libmetaproxy3.
1020 --- 1.1.7 2010/06/30
1022 session_shared: ensure backend session is closed if init rejected
1025 z3950_client: fix NULL ptr reference that could occur if two clients
1026 connected concurrently and if max-sockets was in effect.
1028 --- 1.1.6 2010/06/21
1030 Fix bug 3497 - Metaproxy unstable while stopping.
1032 Fix bug 3495 - SEGV in SRU filter.
1034 --- 1.1.5 2010/06/15
1036 Filter multi throws diagnostic 'Present Out of Range' when
1037 appropriate - rather than returning 0 records.
1039 Filter virt_db: fix bad result reuse. Could happen if a result
1040 was overriden and a backend did not supported named result sets.
1042 --- 1.1.4 2010/05/11
1044 Filter log: category access logs diagnostics even if searchStatus
1045 or presentStatus is 'success'.
1047 --- 1.1.3 2010/04/21
1049 The SRU to Z39.50 filter does repeated Z39.50 present requests
1050 to fetch all records. Needed when a Z39.50 server returns partial
1051 results (due to message size limits).
1053 --- 1.1.2 2010/03/18
1055 Metaproxy now kills all child processes that are spawned by
1056 modules (in case of fork, exec).
1058 --- 1.1.1 2010/01/28
1060 Debian package now installs /etc/metaproxy/metaproxy.xml which
1061 includes all XML files /etc/metaproxy/filters-enabled .
1062 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1064 --- 1.1.0 2010/01/20
1066 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1067 development package to facilitate 3rd party Metaproxy modules.
1069 --- 1.0.23 2010/01/04
1071 Filter virt_db: Close backend filter session when Init rejected is received
1072 from it (in which case it's not really closed yet). This will ensure we don't
1073 run out of resources such as FDs in this case.
1075 sru_z3950 filter: Accept any database (including those not listed).
1077 --- 1.0.22 2009/12/03
1079 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1080 later which means YAZ 3.0.47 or later.
1082 --- 1.0.20 2009/11/19
1084 For filter virt_db, the database is a glob pattern and the virtual
1085 database sections are consulted in the order given.
1087 --- 1.0.19 2009/07/08
1089 For filter multi, the target (for routing) may be given as a glob-pattern.
1091 More documentation for filters virt_db and multi.
1093 Update schema to allow for no database in sru_z3950 filter.
1095 --- 1.0.18 2009/06/30
1097 Added limit filter to put sleep (penalty) for heavy use.
1099 Filter frontend_net may be configured to limit the number of new connections
1100 from same IP to some value (connect-max).
1102 Fixed the load_balance filter.
1104 --- 1.0.17 2009/06/16
1106 Fix path for metaproxy executable for Debian init.d script.
1108 --- 1.0.16 2009/06/10
1110 SRU to Z39.50 filter honors x-username and x-password. If only
1111 x-username is given that translates to open authentication (Z39.50v2). If
1112 both x-username and x-password is present that translates to idPass
1113 authentication (Z39.50v3).
1115 New facility to change current working directory (-w).
1117 Update to upstream skeleton of init.d script. Should fix bug #2619.
1119 Filter session_shared now caches records (used to only cache connections
1122 Filter session_shared now invalidates a Z39.50 session if a server
1123 returns -1 hits. This facility was also part of yazproxy and gets around
1124 a bug in Voyager-based Z39.50 servers.
1126 --- 1.0.15 2008/11/18
1128 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1130 --- 1.0.14 2008/06/09
1132 Fixed the value of SRU record schema in searchRetrieve response. It was set
1133 to a fixed value of "dc" before.
1135 Serialize identical SRU requests. This is useful if HTTP client software
1136 fires identical requests against metaproxy.
1138 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1139 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1140 avoid static configuration. This facility is handled by the sru_z3950 module
1141 and the z3950_client module.
1143 Allow maximum number of sockets to be used for a Z39.50 client by the
1144 use of SRU extra parameter x-max-sockets. This facility is handled by the
1145 sru_z3950 module and the z3950_client module.
1147 --- 1.0.13.1 2008/02/29
1149 Simplified check for Boost libraries.
1151 --- 1.0.13 2008/02/29
1153 First Debian package.
1155 The sru_z9350 filter now recognizes SRU parameter z-target as being
1156 a ZURL of the form host/database .
1158 Mergetype may be specified for filter 'multi'.
1160 --- 1.0.12 2007/09/19
1162 Fixed problem in Makefile WRT library specifictions. This could produce
1163 linker errors (when they should not happen).
1165 Fixed bug #1341: MetaProxy returning different results. Problem was that
1166 fix-up of record database did not normalize the database name.
1168 Documentation updates for Windows compilation.
1170 --- 1.0.11 2007/06/14
1172 Fixed problem with logfile being truncated.
1174 --- 1.0.10 2007/05/23
1176 Fixed bug #1136: Access rights not enforced.
1178 Extension for log module. The log category 'access' logs more details.
1179 New category 'user-access' added which is simlar to 'access' but adds
1180 the Z39.50 user as for all entries in a session.
1184 Added support for configurable default/force target/vhost for module Z39.50
1187 --- 1.0.8 2007/01/25
1189 Implemented filter, session_shared, which optimizes usage of Z39.50
1190 sessions and result sets.
1192 New filter, record_transform, which converts MARC/XML records.
1194 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1196 New filter, load_balance, in development.
1198 New filter, zeerex_xplain.
1200 XML framework for config files started.
1202 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1203 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1204 XML config files are checked against RNG and XML Schema's.
1206 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1207 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1208 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1209 explain record to YAZ CQL-to-PQF text config file.
1211 --- 1.0.7 2006/11/07
1213 Added 'timeout' setting for filter frontend_net which specifies the number
1214 of seconds a session is idle before it is closed. Default timeout is
1217 --- 1.0.6 2006/07/07
1219 Database name in records returned set for virt_db/multi filters.
1221 Filter session_shared now functional.
1223 Log filter can be configured to write to a given file using 'filename'
1224 element. Also information category can be specified with 'category'. If
1225 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1228 --- 1.0.5 2006/05/16
1230 Fixed compilation on Windows.
1232 --- 1.0.4 2006/05/16
1234 Added documentation for the hidenavailable option for the multi filter.
1236 --- 1.0.3 2006/05/16
1238 Fixed bug #573: Hide errors for individual servers. If the element
1239 'hideunavailable' is given in the configuration, individual servers
1240 being unavailable are hidden (unless all are unavailable).
1242 Fixed bug #574: Database names are recognised case-sensitively.
1244 Fixed bug #567: Fix up database name in Name-Plus-Record.
1246 Fixed bug #568: Update win/makefile for VS 2005.
1248 Fixed bug #569: Some options throws unknown exception.
1250 --- 1.0.2 2006/04/28
1252 More information about virtual hosts. The 'etc' directory is part of the
1255 --- 1.0.1 2006/04/27
1257 Build instructions for Windows. NMake makefile part of distribution tar.
1259 --- 1.0.0 2006/04/24
1263 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1264 log, multi, query_rewrite, template, virt_db, z3950_client.
1266 Filters in development: session_shared.
1268 Pseudo-filters: template, dl
