We've been running on MW 1.4 for longer than we should have been, and tried upgrading today to 1.6.7. We're running a Squid server on one machine, and PHP 4.4.2 with Apache 2.0.46 with eAccelerator installed on another, and then a third server for mySQL 4.1, all machines are Linux. I did a db dump, imported it into a new database, went through config/index.php to convert the new database and pointed Apache to the new source directory. The load on the Apache server went through the roof and won't stay down. I tried restarting Apache, rebooting the server, any way to bring the load down to 0, then started Apache and Squid back up, and the load would go through the roof again - and it stays there. The database shows a lot of open & sleeping connections, but none are locked. Switching back to 1.4 seems to solve the load problem. Any ideas? Did I miss something during the upgrade process?

Unknown SQL error while running command like maintenance script

by Travis Derouin

Hi, I've been getting a unknown SQL error for any function that uses the DB_SLAVE database (I only have 1 database) when running a script from the command line. The script is pretty basic, it's just cleaning up some talk pages that have broken HTML in them. I've done what maintenance/cleanUpSpam does with $dbw =& wfGetDB( DB_MASTER ); $dbw->immediateBegin(); and then $dbw->immediateCommit(); wfDoUpdates(); but am getting this error: any ideas? PHP Warning: mysql_query(): Unable to save result set in /var/www/html/wiki16/includes/Database.php on line 435 Warning: mysql_query(): Unable to save result set in /var/www/html/wiki16/includes/Database.php on line 435 A database error has occurred Query: SELECT old_text,old_flags FROM `text` WHERE old_id = '197785' LIMIT 1 Function: Revision::loadText Error: 2000 Unknown MySQL error (10.234.169.196) Backtrace: GlobalFunctions.php line 602 calls wfbacktrace() Database.php line 473 calls wfdebugdiebacktrace() Database.php line 419 calls databasemysql::reportqueryerror() Database.php line 806 calls databasemysql::query() Database.php line 825 calls databasemysql::select() Revision.php line 667 calls databasemysql::selectrow() Revision.php line 435 calls revision::loadtext() Revision.php line 424 calls revision::getrawtext() Parser.php line 2805 calls revision::gettext() Parser.php line 2642 calls parser::fetchtemplate() - line - calls parser::bracesubstitution() Parser.php line 2231 calls call_user_func() Parser.php line 2319 calls parser::replace_callback() Parser.php line 2725 calls parser::replacevariables() - line - calls parser::bracesubstitution() Parser.php line 2231 calls call_user_func() Parser.php line 2319 calls parser::replace_callback() Parser.php line 824 calls parser::replacevariables() Parser.php line 231 calls parser::internalparse() Article.php line 2303 calls parser::parse() Article.php line 1493 calls article::editupdates() cleanupTalkPages.php line 18 calls article::updatearticle() cleanupTalkPages.php line 35 calls cleanuparticle()

pywikipediabot does not run on pms wikipedia, but works on nap and vec

by Sabine Cretella

Hi, I am trying to run my bot on pms.wikipedia.org (User RobotSC) I already have bot status on pms wikipedia. For some reason it does not allow for login with login.py I just tried to do the same on nap and vec: there it works. I checked the user-config.py twice, so it should not be a problem. Could it be that bots are not allowed on pms wikipedia? Thank you for having a look. Best, Sabine Chiacchiera con i tuoi amici in tempo reale! http://it.yahoo.com/mail_it/foot/*http://it.messenger.yahoo.com

Image deletions not logged

by Timwi

Hi, I just deleted about 10 images or so on English Wikipedia. Only three of them show up in the deletion log -- maybe because these three had pages associated with them, while the others may not have. I think this is a significant bug that needs to be fixed, but I'm too tired to search MediaZilla for it now. Someone please report it for me, or explain why it's not a bug :-) Timwi

Languages*.php/Messages*.php proposed changes

by Tim Starling

I'm making some changes to MediaWiki's localisation files, to make them easier to write, and to improve loading speed at runtime. I've often complained about the fact that MediaWiki's LanguageXx.php files force every would-be translator to also be a programmer. What I'm doing with this change is to make it so that in 90% of cases, a LanguageXx.php file won't be necessary, its function will be replaced by the simpler MessagesXx.php file. The format of the MessagesXx.php file will look like this: <?php $fallback = 'en'; $rtl = false; $timeBeforeDate = true; $timeSeparator = ':'; $timeDateSeparator = ', '; $digitTransformTable = null; $separatorTransformTable = null; $namespaceNames = array( NS_MEDIA => 'Media', ... ); $quickbarSettings = array( ... ); $skinNames = array( ... ); $mathNames = array( ... ); $dateFormats = array( MW_DATE_DEFAULT => 'No preference', ... ); $bookstoreList = array( ... ); $weekdayNames = array( ... ); $monthNames = array( ... ); $monthNamesGen = array( ... ); $monthAbbreviations = array( ... ); $magicWords = array( # ID CASE SYNONYMS 'redirect' => array( 0, '#REDIRECT' ), ... ); $messages = array( ... ); ?> Note that there are no globals, no classes, and no language code variable name suffixes. The language code is simply specified by the filename. The $fallback variable specifies a fallback language which should be used if anything in the present localisation file is missing. If $fallback is missing, English will be used. If the localisation is sufficiently specified by these variables (and any others we think need to be added), then the LanguageXx.php file will not be needed. In cases where the language file needs to be kept, due to special code, all of the customised accessors for the above variables will be deleted, leaving only the special code. The contents of the MessagesXx.php files will be cached, if a cache is available. The modification time of the file will be checked on every request, so when the file is updated, the cache is immediately invalidated. I've already done most of the technical work for this change, including converting three languages as a pilot. Most of what remains is the rote work of converting all of the language files. I might consider committing what I've done to a branch, if someone else wants to help out with this. Also in my working copy at the moment is a scheme to delay the initialisation of most object global variables, but that's a topic for another post. -- Tim Starling

AOL proxies, etc. (re-sent, this time without the attachments)

by Neil Harris

[This is the E-mail I am referring to in the message that now precedes this, since it bounced the first time round, since I included a load of attachments with the original] I read on the mailing list that AOL are turning on XFF on their proxies. I have been poking around a bit to find out how the AOL proxy information squares up with reports of AOL vandalism. == The boring details == First, I did a DNS reverse lookup on the entire AOL Proxy IP range, as defined in http://webmaster.info.aol.com/proxyinfo.html using dig in batch mode. Out of the 56542 addresses in those ranges, only 6740 give a valid reverse lookup. I then went through the list of 116 pages flagged with the {{AOL}} template, and extracted their IP addresses, and compared them to the list of reverse lookups generated above. Out of 116 pages with addresses flagged with {{AOL}}: * 76 were found in the list of reverse lookups generated above, and every one of them had an address of the form *.proxy.aol.com * 40 were not I then ran the 40 remaining addresses through dig -x. Of these, 32 had valid reverse lookups, most of which were of the form [8 hex digits, starting with AC].ipt.aol.com (for example, ACA40DC5.ipt.aol.com.) Every single one of these was in the address range 172.128.0.0 - 172.216.255.255, assigned to AOL clients according to the AOL proxy info page. Five of the addresses flagged with {{AOL}} did not belong to AOL addresses at all, namely: 195.9.72.12.in-addr.arpa. 172768 IN PTR 195.los-angeles-19-20rs.ca.dial-access.att.net. 22.2.25.138.in-addr.arpa. 86369 IN PTR www2.itd.uts.edu.au. 176.72.250.134.in-addr.arpa. 86370 IN PTR elc214-176.lab.suu.edu. 10.219.196.205.in-addr.arpa. 272 IN PTR franc.dreamhost.com. 5.21.196.69.in-addr.arpa. 1773 IN PTR CPE00609425bbe3-CM00080d7f2c84.cpe.net.cable.rogers.com. The remaining five {{AOL}}-flagged pages, which appear to have no reverse lookup at all, are (with whois lookups): ;163.130.157.152.in-addr.arpa. -> 152.157.130.163 -> Washington School Information Processing Cooperative ;106.209.188.205.in-addr.arpa. -> 205.188.209.106 -> AOL ;76.164.174.149.in-addr.arpa. -> 149.174.164.76 -> Compuserve (ie AOL) ;234.96.12.64.in-addr.arpa. -> 64.12.96.234 -> AOL ;135.209.188.205.in-addr.arpa. -> 205.188.209.135 -> AOL and of the last four given as AOL addresses, all of them were in the AOL server IP address ranges given by AOL. == Summary == Out of all of the 116 pages flagged as {{AOL}}: * six are bogus non-AOL addresses, and are probably attempts by vandals to confuse anti-vandalism efforts * 32 are from the AOL client range, with *.ipt.aol.com reverse lookups * 76 are from the official AOL proxy range, with *.proxy.aol.com reverse lookups; they all appear to be either of the form cache-XXX-XXXX.proxy.aol.com [74 of them], or spider-XXX-XXXXX.proxy.aol.com. [2 of them] * four have no reverse lookup, but are in the official AOL proxy range Out of the 458 cache-*.proxy.aol.com servers, only 74 are flagged with {{AOL}} Out of the 2537 spider-*.proxy.aol.com servers, only 2 are flagged with {{AOL}} == Conclusions == * It seems safe to assume that *.proxy.aol.com servers are valid AOL proxies; these account for about two-thirds of all {{AOL}} warnings * It _might well_ be safe to assume that other servers from the AOL server range without reverse lookups are also AOL proxies, but I'm not sure that this is necessarily so; these account for < 5% of the valid {{AOL}} warnings. * But about a third of {{AOL}} warnings are about IPs with reverse lookups of the form *.ipt.aol.com in the AOL client IP address range: are these AOL proxies or not? They might, for example, be dynamically assigned client addresses. If so, we should _definitely not_ be trusting any XFF headers from these. [On review: not all the figures sum to 100% so I may have dropped a couple in my counting, but I think the overall conclusions still hold up] -- Neil

Ontology import

by Mei Wu

Hi all! I am trying to import Ontologies into Mediawiki. I downloaded a couple of ontologies from the web in .rdf format and imported them using the "Import ontologies" Special page. However, every time I hit Import an error message appears (see below). I am running MediaWiki 1.6.7 and SemanticMediaWiki extension 0.4.3.2. I also added the rdfapi-php to the SemanticMediaWiki "libs" folder. It looks like the .php script is not recognized but I do not really know what the problem is. Does anybody has experiences with importing ontologies and have an idea what the cause of this problem might be? Thank you very much!

Custom left nav per namespace?

by Mick Monaghan

Hi, Is it possible to have a custom left navigation for a custom namespace? Or is 'MediaWiki:Sidebar' applied to all pages in a wiki, regardless of the namespace? Thanks, ~mm
