 * Brion needs to review the patch. It can be fixed if needed, resubmitted and committed then. He'll also have to run write queries on a good set of wikis. Voice of All 17:40, 27 January 2007 (UTC)

new version
so is the new version we're seeing now your work?

and can we still get to the old version, or do we have to abandon all checkuser efforts prior to today? --En.jpgordon 21:24, 7 April 2007 (UTC)


 * Yes, Tim reviewed it and added a nice batch db script to migrate the data into the new table. The old version is no longer accessible, though I am not sure why you would need it though. The data should still be accesible. Voice of All 22:22, 7 April 2007 (UTC)


 * Just a small matter, I guess, of actually doing the migration? Right now, checkuser on enwiki shows no information for anyone prior to this morning. --En.jpgordon 00:05, 8 April 2007 (UTC)
 * Tim wrote a small batch install.php file, that should copy the stuff over slowly enough so as not to cause downtime/lag. It seems odd that he would svn up and then run it though. I'll talk to Tim. Voice of All 01:17, 8 April 2007 (UTC)

"Installing" with or without so called "command line"
I'm trying to install this on my wiki, but I don't have access to a command line to run install.php. I've tried SSH-ing to my domain, only to be told that exec is forbidden. I've tried using phpShell, but that wouldn't work. Short of running off to my host's tech support, is there anything I can do? --62.254.220.101 18:43, 27 April 2007 (UTC)


 * Peter Blaise adds: I have access to the server (WinXPPro) and I also can't "run Install.php" - "run" is not a command. Now what?  Do you mean to open the install.php command with the php.exe executable program?  By doing what?  My   ... and php.exe is in the   directory.
 * Also, why add  when I have no such directory or file - you told us to put them directly in the "extensions" directory, so wouldn't the line to add to LocalSettings.php be:   ?  Anyway, without running "install.php" first, nothing works, and the wiki contents just get replaced by a bunch of file listing code until I comment out the "// include..." line.  Thanks. -- Peter Blaise peterblaise 18:12, 19 June 2007 (UTC)
 * The "Checkuser" folder, from SVN, should go in the extensions/ directory. Also, did you open cmd.exe, then type in ? Aaron 20:30, 19 June 2007 (UTC)

So without shell access to the webserver I can't install CheckUser? --89.244.177.62 19:07, 19 February 2008 (UTC)


 * My question exactly. I am on share hosting and have no shell access ... how to install this extension without it? Thanks.--Nonegiven 17:41, 24 February 2008 (UTC)
 * In short, it's not really possibly without shell access (insofar as I can fathom possible installation methods). Anthøny 21:07, 13 June 2008 (UTC)


 * I can't get access to a command shell on my host - without this the extension cannot be made functional. There should be a more "normal" way of installing this - every other extension I have installed just requires ftp of the relevant files and changes to localsettings.php.  Peter Campbell 12:41, 7 August 2008 (UTC)


 * Feel free to run the SQL queries from install.inc on your database directly (at your own risk, of course). —Emufarmers(T 16:23, 7 August 2008 (UTC)
 * But is there no list of what query exactly? I'm a very basic user, I have access and all that and can grasp what the command does, but I fear I'm not adequate to make the query myself. Sidearm 11:58, 23 December 2008 (UTC)


 * Why Shell? Why not directly? Is there any other better extension? --144.122.250.204 22:23, 14 November 2008 (UTC)

Recent Changes malfunction
After installing this on 1.10.0 new edits stopped appearing on Recent Changes page. Removed extension and even ran maintenance/rebuildrecentchanges.php, but still don't have edits showing up on Recent Changes.

Any pointers on how to get this function back? Mburp 05:32, 17 June 2007 (UTC)


 * Likely a configuration issue or something unrelated to the extension, especially if rebuildrecentchanges.php doesn't add new entries. Aaron 19:29, 17 June 2007 (UTC)


 * Wait do you mean new edits not showing in checkuser only? Aaron 19:30, 17 June 2007 (UTC)

No. New edits are not showing up on Special:Recentchanges. At first I thought this might be tied to Check User because it first cropped up immediately after I installed that extension. Now I'm not so sure; it may have been a coincidence.

After digging in further, I realized that new edits are still being added to the recentchanges db table and they are displaying correctly in My Watchlist, which seems also to draw from that table. For some reason, recent edits just aren't displaying on Special:Recentchanges.

If I run rebuildrecentchanges.php, edits added by that script are added to the database - newest first, oldest last - and do display on Special:Recentchanges, but any new edits after that go to the bottom of the db table and do not display on Special:Recentchanges. (They will, however, display on My Watchlist.)

I've actually reinstalled CheckUser and it seems to work - its data base table also seems to be staying up to date.

I've replaced all mediawiki files with fresh uploads in case one had become corrupted. I've tried stripping out all extensions which would have removed any recent changes to LocalSettings.php. I've tried running rebuildAll.php

Anyway, thanks for answering. I left a help request MediaWiki's Project:Support desk, but I'm afraid MediaWiki is living up (down?) to its reputation for support.

You can remove all this if you believe its not related to the Check User installation.

Mburp 04:31, 18 June 2007 (UTC)
 * Perhaps you have a local system clock issue causing new entries to be added with old timestamps? Aaron 04:35, 18 June 2007 (UTC)


 * I don't know really how to fix this, but I believe this is the same problem that I had with my test installation of MediaWiki 1.10 with CheckUser. I think the software gave me some kind of an error when I changed my group membership from bureaucrat, sysop to bureaucrat, sysop aand checkuser, though CU wasn't fully functional (or even installed) then. It gave me an error, I clicked "back", had a look on the RC, saw the log entry, made a test page and it didn't show up on RC... -- Sayuri 08:41, 18 June 2007 (UTC)

That would make sense. It now seems that I somehow turned on 'Autopatrol' for myself and the other admin - the site is still under construction and we're the only two making edits. I, too, added check user as well as bot privileges for both of use about the same time I added check user. Until then all of our edits were showing up in RecentChanges; since then, none.

My apologies from bringing this problem here. It is a configuration problem after all. Again, for my part this may be deleted. Mburp 09:54, 18 June 2007 (UTC)
 * Do you have the latest version from SVN? Aaron 17:43, 18 June 2007 (UTC)

Yes or as of about two days ago. My site is still under development and until this problem arose I had made all the edits on with the sysop privilege I acquired during installation.

I added Makebot and Makesysop at about the same time as Checkuser and added full privileges for the two admins. Until then my edits had been appearing in Recent Changes and then they stopped. I tried a sock puppet registration and a few edits with that and anonymously - and they appear in the Recent Changes page. It looks like changing our privileges brought us under 'autopatrol' so my edits are no longer appearing in Recent Changes.

This is clearly not a Check User error - not an error at all; just a newby's mistake. Again, I apologize, and thank you for your help.

CheckUser accountability log
I'd like to see an automatic public log of all CheckUser requests, which would show date/date, User performing CheckUser, and on which Users. It would not show the results (as they might be private and non-supportive). This would ensure there is accountability, and show any abuse of the system. --84.9.191.165 11:06, 16 September 2007 (UTC)

Self-checkuser
Any reason why an individual could not be allowed to perform a checkuser on themselves? It might encourage some individuals not to abuse the system by allowing them to see the information that is available to the sytesm. It would also allow a user to keep a copy of the information that can be obtained by certain administrators --84.9.191.165 15:21, 1 November 2007 (UTC)

Lots of error messages when trying to install
I set everything in the extensions/CheckUser folder to chmod +x *. Then I try to run install.php, and I get an infinite loop of error messages, saying stuff like: ./CheckUser.i18n.php: line 1: ?php: No such file or directory ./CheckUser.i18n.php: line 2: /bin: is a directory ./CheckUser.i18n.php: fork: Resource temporarily unavailable ./CheckUser.i18n.php: line 6: archives/: is a directory ./CheckUser.i18n.php: line 8: syntax error near unexpected token `(' ./CheckUser.i18n.php: line 8: `$messages = array;' What's the deal with that? By the way, I am running a wiki that I expect may come under vandalism at any time, but I would like to leave it open to editing by the general public. I have no need to install CheckUser if no vandalism occurs, but if it does, I would be interested in knowing the IPs behind the responsible accounts. Will CheckUser let me run a CheckUser on a user's edits that occurred before CheckUser was installed? Thanks, 70.22.118.41 00:48, 29 June 2008 (UTC)

Manual install w/o shell access
I'm trying to do this; I think I've found a way, if a developer thinks this is sound, they should stick this out on the page. I'm not able to try this until later today, but it looks like a way. Will attempt later. JeremyMcCracken 21:48, 17 February 2009 (UTC)
 * 1) Create two new tables in the wiki database, "cu_changes" and "cu_log".
 * 2) In the downloaded CheckUser files are "cu_changes.sql" and "cu_log.sql".
 * 3) Open those files as text and use the data to create the fields in the corresponding table. They list fields, followed by type, default value, length, etc.
 * Worked partially; I don't know the command syntax for SQL, and didn't know how to implement the "INDEX" statements at the bottom. I discovered that phpMyAdmin has a thing to insert SQL code, so I'm going to drop the file into that and see if that works. JeremyMcCracken 00:42, 18 February 2009 (UTC)

Working solution for phpMyAdmin users
If you have this available (I don't know if it always is, or if you can install it by uploading), follow these steps: Someone with the resources available should test this for themselves, and include it if it appears to always work. I have it apparently 100% working on a site at freehostia- user rights assignment, checkuser, and CU log all come up without errors. JeremyMcCracken 00:51, 18 February 2009 (UTC)
 * 1) Download cu_changes.sql and cu_log.sql
 * 2) Open each in a text editor; remove the HTML-looking headers, leaving only what was inside the "PRE" tags; save
 * 3) In phpMyAdmin, click the database you're using for mediawiki along the left side
 * 4) On the next screen, click the "SQL" tab at the top
 * 5) At "Location of the text file", choose one of the files, select compression "None", and click the bottom "Go" button
 * 6) Repeat for the second file

Command Prompt

 * '''Open command prompt and run php install.php

 * Okay, if you got that far it's almost certainly installed. The problem is, CU creates a user rightcalled "check users" that you have to assign to the name(s) that will use it- when you installed MediaWiki, it created the first name with Bureaucrat and Administrator only. Use the user rights interface to add the check user right, and you should be set. JeremyMcCracken 00:34, 14 March 2009 (UTC)
 * THANK YOU SO MUCH!!! It works now. Thank you for your help. 86.136.108.50 08:18, 14 March 2009 (UTC)

Similar problem
I have the same problem as the anon, except I am a complete newb at phpMyAdmin. Would this workaround work with Mediawiki 1.7.1? That is the version I have.

I download the files for older wikis and placed them in a "CheckUser" folder in my extensions folder.

My phpMyAdmin is: Server version: 4.1.22-standard-log

Here is what I have done:
 * 1) Download cu_changes.sql and cu_log.sql
 * 2) Save each file as .txt.
 * 3) In phpMyAdmin, click the database you're using for mediawiki along the left side
 * I clicked database "wiki"
 * 1) On the next screen, click the "SQL" tab
 * In the Run SQL query/queries on database nameofmywiki_wiki:
 * I copied and pasted the contents of cu_changes_sql and clicked Go. The page timed out.
 * But when I tried a second time, it said that:
 * # 1050 - Table 'cu_changes' already exists
 * 1) At "Location of the text file", choose one of the files, select compression "None", and click the bottom "Go" button
 * The "Location of the text file" is only available when I click the SQL button, not the SQL tab. There is no compression option.
 * 1) Repeat for the second file.



I went to my wiki, to the Special:CheckUser page, and it said:
 * No such special page
 * You have requested an invalid special page, a list of valid special pages may be found at Special:Specialpages.

But I get a similar page like anon above. (see photo)

Odessaukrain 18:07, 29 June 2009 (UTC)


 * Hmm... your PHPmyAdmin looks different from mine; I suspect a version thing. I have version 4.1.22-standard-log as my MySQL version; the PHPmyAdmin version is 2.6.4-pl2 (it's in the window title on mine). On the first screen you've uploaded, mine has a text box that is much larger than one line, and the file selector is underneath that.


 * My phpMyAdmin also lacks the drop-down menu in the left column. I found a screenshot online that has this drop-down menu, and it identifies as phpMyAdmin 2.10. See ; you'll have to copy+paste that b/c the site blocks referrers. Apparently the option I used was removed at some point.


 * The method you've supplied seems to be an alternative way, but I couldn't tell you why the request timed out. That would seem to suggest a problem with the server. The error about cu_changes already existing seems to indicate it partially installed. I'd suggest deleting cu_changes and cu_log entries and running the text files through again. Also, be sure you're remembering to add the line in LocalSettings.php, and check the permissions on AdminSettings.php. JeremyMcCracken 08:13, 2 July 2009 (UTC)

I wonder for what period of time checkuser logs are present in the database for the version installed in WMF projects? In other words, is it possible to get an information about an edit made, say, a year ago unless it has been logged before? --Peter Cunning 16:44, 28 December 2010 (UTC)


 * No. CheckUser data is retained for three months. —Emufarmers(T 21:49, 28 December 2010 (UTC)

Installation problem
I'm running a local copy of Mediawiki. I use PHP 5.2, and Sqlite on Apache (Windows 7 64 bit). I tried installing this extension, along with Oversight and some others, and when I had to run the php command (php install.php) on cmd, it gave me an error: I think the problem is that I run Sqlite, but I'm not sure. What should I do? Manishearth 15:56, 27 January 2011 (UTC)
 * I haven't looked at this extension with SQLite, but here's what needs to be hacked to create the schema:


 * Replace cu_log.sql with:
 * And cu_changes.sql with:

 * Thanks! Is there any way I can do this so that other extensions also work? Or should I just reinstall mw with MySql (I'm fine with that) Manishearth 09:17, 28 January 2011 (UTC)
 * I reinstalled. It works! Thanks. Manishearth 11:15, 28 January 2011 (UTC)

Help please
Getting the message:

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

(SQL query hidden)

from within function "efUpdateCheckUserData". Database returned error "1146: Table 'everques_wikidb.few_cu_changes' doesn't exist (localhost)".

I installed Extension:CheckUser by using the Installing without command prompt access through phpMyAdmin.

Thanks. 24.136.137.125 04:50, 19 April 2011 (UTC)
 * Apparently, you didn't prefix the table names with few_</tt> when creating schema via phpMyAdmin. Replace every occurence of /*$wgDBprefix*/</tt> with your prefix. Max Semenik 04:59, 19 April 2011 (UTC)

Thank you so very much, Max Semenik. Problem fixed. 24.136.137.125 18:27, 19 April 2011 (UTC)

Nuke
since this extension changes the recent changes table, how does this extension affect the NUKE (mass delete) extension ?

No data collected (solved)
I installed CheckUser on MW 1.16.4 as described in Extension page (version without shell access) and there is no data collected or returned by CheckUser interface. cu_changes table is empty, even after I opened new browser session and logged in with another user account. Later I found that my latest login is collected/displayed. And I reinstalled CheckUser with "shell access" - using a Cron job. After installing with "shell access", history was imported, but my test login still wasn't logged. Probably I understood the situation:
 * logins are not logged until user edits something;
 * previous history is shown only if using installation method with shell access.

Install.php
Install.php is not listed on:
 * Manual:Maintenance scripts

I must be missing something. Errectstapler 19:01, 4 May 2011 (UTC)
 * Because that page is for core scripts only. Each extension documents its own scripts on its own page, to avoid a complete mess. Max Semenik 19:12, 4 May 2011 (UTC)
 * oh thank you. Still very confused, but thanks for responding. I checked my maintenance folder, and there is no install script. I don't move the install.php in the checkuser folder to the maintenance folder do I? I am so confused. Thanks. Errectstapler 19:42, 4 May 2011 (UTC)
 * i figure this out. What crumby instructions :) thanks for responding. Errectstapler 19:49, 4 May 2011 (UTC)

Bug during installation - MediaWiki 1.17.0 and Windows XP 32 bits
Hello,

When I run install.php on Windows XP 32 bits, with MySQL and WampServer 2.1, I have the following error :

A database query syntax error has occurred. The last attempted database query was: "CREATE TABLE `cu_changes` ( cuc_id INTEGER NOT NULL AUTO_INCREMENT, cuc_namespace int NOT NULL default '0', cuc_title varchar(255) binary NOT NULL default , cuc_user INTEGER NOT NULL DEFAULT 0, cuc_user_text VARCHAR(255) NOT NULL DEFAULT , cuc_actiontext varchar(255) binary NOT NULL default , cuc_comment varchar(255) binary NOT NULL default , cuc_minor bool NOT NULL default '0', cuc_page_id int(10) unsigned NOT NULL default '0', cuc_this_oldid int(10) unsigned NOT NULL default '0', cuc_last_oldid int(10) unsigned NOT NULL default '0', cuc_type tinyint(3) unsigned NOT NULL default '0', cuc_timestamp CHAR(14) NOT NULL default , cuc_ip VARCHAR(255) NULL default , cuc_ip_hex VARCHAR(255) default NULL, cuc_xff VARCHAR(255) BINARY NULL default '', cuc_xff_hex VARCHAR(255) default NULL, cuc_agent VARCHAR(255) BINARY default NULL, PRIMARY KEY cuc_id (cuc_id), INDEX cuc_ip_hex_time (cuc_ip_hex,cuc_timestamp), INDEX cuc_user_ip_time (cuc_user,cuc_ip,cuc_timestamp), INDEX cuc_xff_hex_time (cuc_xff_hex,cuc_timestamp), INDEX (cuc_timestamp) ) TYPE=InnoDB" from within function "DatabaseBase::sourceFile( C:\wamp\www\Ref\extensions\CheckUser/cu_changes.sql )". Database returned error "1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to usenear 'TYPE=InnoDB' at line 25 (localhost)"

Is there anyone could help resolve this error ? Thank you in advance and sorry for my bad english. Workworkwork 17:43, 13 August 2011 (UTC)
 * In LocalSettings.php, find $wgDBTableOptions and change TYPE=InnoDB</tt> to ENGINE=InnoDB</tt> in it. Max Semenik 18:22, 13 August 2011 (UTC)
 * Actually it was already set to ENGINE=InnoDB</tt> in LocalSettings.php. In file cu_changes.sql I have modified TYPE=InnoDB</tt> and I have changed to ENGINE=InnoDB</tt> and it works now. Workworkwork 21:37, 13 August 2011 (UTC)

use with reverse proxy
Er, I got a situation like this. Our site uses a reverse proxy (squid) and CheckUser inspection of user edit will return something like this:

IP: aaa.aaa.aaa.aaa  XFF: bbb.bbb.bbb.bbb, ccc.ccc.ccc.ccc   Mozilla/5.0 (......)

,where aaa is the ip for reverse proxy, bbb is the client ip, and ccc is one of our load balancers (CDN). If a spam-bot creates pages or edits on our wiki, we are not supposed to block it along with its last IPs, because doing that will block all other clients requesting our pages through the reverse proxy (aaa). This has been tested for sure.

I was wondering how I can block certain related IPs of a user while not blocking the entry through the reverse proxy. Thanks a lot! --Ccyber5 16:19, 20 October 2011 (UTC)


 * There are several variables you can set which relate to Squid. —Emufarmers(T 20:39, 20 October 2011 (UTC)
 * Thanks! I'll try $wgUseSquid and $wgSquidServers to see if it will do. --Ccyber5 08:18, 21 October 2011 (UTC)
 * It appears that since IP records is all right after setting the variables, the submit of edit seems to take longer times than before, even if the access is through internal network rather than through external CDNs. A Firebug test indicates that it takes more than 6 seconds to complete a submit now, while it took about less than 2 seconds before (internal network). --Ccyber5 04:49, 25 October 2011 (UTC)
 * $wgSquidServers purges Squid when the page is edited. That could be causing the slowdown.  You might want to try $wgSquidServersNoPurge instead (though, of course, this may lead to stale data in Squid!). —Emufarmers(T 04:02, 27 October 2011 (UTC)
