Extension talk:Usage Statistics

Translation
Here is the french version of messages:

I don't know if i can add that in the main page myself ?!


 * Thank you for the translation! I have added it to the source code. I also moved the extension into Subversion (see main page for installation instruction changes). --Gri6507 13:50, 7 January 2008 (UTC)

Warning
Hi Im getting this error when I load page. Otherwise everything appears to work fine.

"Warning: Cannot modify header information - headers already sent by (output started at /var/www/ /extensions/SpecialUserStats.php:19) in /var/www/ /includes/WebResponse.php on line 10"

Cant find that error reported anywhere for SpecialUserStats; please help.
 * What version of the extension are you using? Version 1.2 only has 17 lines in SpecialUserStats.php, so this warning seems a little odd. Can you please post the contents of your SpecialUserStats.php? --Gri6507 14:53, 20 October 2007 (UTC)

Found out what it was - php.ini still on default settings. Changed it to stop error logging to screen and it is fine now. --86.134.183.173 12:47, 3 November 2007 (UTC)

Bug
In your body class, you have hard-coded "wiki_" as the database table prefix. You should use $wgDBprefix instead. Here is a diff.

A better fix
From Rob Church:

Actually, you should use the Database::tableName method to obtain the fully-prefixed name for a table; this also respects shared table settings, e.g. for users.

In general, though, use the Database::select and other query-builder/wrapper functions to perform queries, if at all possible


 * it does a lot of the work of escaping various bits and dealing with constructing IN ( ..., ... ) clauses, and all manner of options and other fun.


 * Thanks to both for pointing this out. I know better than to hardcode values into code. It's just that I wrote that extension a long time ago - before I knew anything about prefixes. This has been updated in code v1.1. --Gri6507 16:26, 21 September 2007 (UTC)

Data displayed for all users
Hi,

I don't understand the data I get displayed for all users. Here's an example (intervall=day, start-date 09/13/2007, end-date 09/24/2007):

Username, Edits, Pages,09_13_2007,09_14_2007,09_15_2007,09_16_2007,09_17_2007,09_18_2007,09_19_2007,09_20_2007,09_21_2007,09_22_2007,09_23_2007,09_24_2007 0.0.0.0,1,1,1,1,1,1,1,1,1,1,1,1,1,1, Kate,12,4,12,12,12,12,12,12,12,12,12,12,12,12, Kremser,3,1,3,3,3,3,3,3,3,3,3,3,3,3, MediaWiki default,1,1,1,1,1,1,1,1,1,1,1,1,1,1, Roddeck,380,18,380,380,380,380,380,380,380,380,380,380,380,380, Studi,3,3,3,3,3,3,3,3,3,3,3,3,3,3, Weinreich,62,7,61,61,61,61,61,61,61,61,62,62,62,62, WikiSysop,26,10,26,26,26,26,26,26,26,26,26,26,26,26, Wolkwitz,475,44,450,450,450,450,450,450,450,452,456,475,475,475,

Can somebody explain what those numbers are supposed to mean and if there is another way the data could be formatted?

 * This data is a Comma Separated Value (CSV) list of all user's usage. The data is listed in rows, where the first columns are:
 * Username - the name of the user for whom the row of data applies
 * Edits - the total number of times, including today, the user has edited any page. This should be equivalent to the number of times the user pressed the Save Page button when editing
 * Pages - the total number of unique pages, including today, the user has edited. The previous column could have a very large number if the user prefers the Save Page button instead of the Show Preview button. In other words, a user can have a large number of edits for a single page. The value in this column will always be less than or equal to the Edit column.
 * date - the total number of edits (see ''Edit column definition above) up to and including the date listed in the column heading.
 * Hopefully that clears things up. --Gri6507 12:08, 25 September 2007 (UTC)

SQL-Error
Hi,

when I try to get a by-day-display for my wiki for a longer period of time (for example start-date: 07/01/2007, end-date: 09/24/2007) I get the following SQL-Error-Messages:

Fehler in der Datenbank Es gab einen Syntaxfehler in der Datenbankabfrage. Die letzte Datenbankabfrage lautete: (SQL-Abfrage versteckt) aus der Funktion „SpecialUserStats::GetUserUsage“. MySQL meldete den Fehler „1111: Invalid use of group function (localhost)“.

When I try to get the day-to-day statistics for start-date: 09/01/2007, end-date: 09/24/2007, there's no error-message but the wiki seems to hang itself up... I just get the hourglass and nothing more. Stopping the page request via browser doesn't help, restarting the browser doensn't help either. Restarting Xampp works but seems no usable solution. :-(

 * I have been able to reproduce this problem. The issue seems to be that there is a maximum length to the SQL query and in this instance, you are exceeding it. The basic problem is that the extension is written so that the SQL query is written in pieces, where every new date for which statistics is requested increases the length of the query. After a certain number of dates, and unfortunately, I don't know how many that would be, the SQL buffer is overrun and bad things happen. I need to fix this but I'm no SQL guru. It will take me some time to figure out the proper SQL query to avoid this. Perhaps someone can help me on that?


 * In the mean time, what you can do is split your query into several fragments. So, instead of going from 07/01/2007 to 09/24/2007 in one execution, split that into several like 07/01/2007 to 8/1/2007, then 8/1/2007 to 9/1/2007, and then 9/1/2007 to 9/24/2007. Alternatively, switch to a weekly interval. --Gri6507 12:14, 25 September 2007 (UTC)


 * This has been addressed in v1.2. --Gri6507 19:41, 29 September 2007 (UTC)

Another Bug
I tried installing this extension, but it just spews thousands and thousands of lines of errors to the php log, which look like:

[14-Dec-2007 16:46:45] PHP Notice: Undefined index:  4428 in \SpecialUserStats_body.php on line 88

Any ideas/suggestions/etc? I'm pretty sure I followed the instructions carefully...


 * It looks like this is just a settings issue with your PHP environment, which seems to have an over zealous error reporting setup by default. If you add  to either your php.ini or to the beginning of SpecialuserStats.php, you should not get this error message any more. --Gri6507 16:55, 15 December 2007 (UTC)


 * That fixed it, thanks. A follow-up question: our wiki is tied to LDAP, which means that /nobody/ is allowed to create user accounts. How would I replace that check with (say) a check for sysop or bureaucrat status, when deciding whether to generate the graph for all users? Thanks! --Mbeerman 15:37, 17 December 2007 (UTC)


 * Glad to hear it worked. To address your access issue, you can change  to something like , then add some new group to your wiki with the proper name, and add some priviledged users to that group. --Gri6507 16:37, 17 December 2007 (UTC)


 * Last but not least: When graphing data by month, there seems to be a bug where it cuts the leading digit off of October, November, and December (e.g. you see 0/01/07 for October 1st.) --Mbeerman 17:11, 17 December 2007 (UTC)

Installation Trouble
I have followed the installation steps and am getting no results. No new entry in special pages. I did notice that both SpecialUserStats.i18n.php and SpecialUserStats.php in the SVN are missing closing php tags. Makes me think more might be missing from these files. Help?


 * The missing ?> tags are actually intentional, so that's not the problem. My first suggestion is to make sure that you have added the call to require_once inside your LocalSettings.php file. If that is correct, then take a look at your web server error log. Let me know if you are still have problems. --Gri6507 16:31, 15 January 2008 (UTC)

Trouble with MediaWiki 1.11.0
Hi,

after upgrading from MediaWiki 1.10.0 to MediaWiki 1.11.0 I get the following error messages when I hit "Generate Statistics":

Warning: mkdir [function.mkdir]: Permission denied in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 51 Warning: chmod [function.chmod]: No such file or directory in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 52 Warning: fopen(/opt/lampp/htdocs/_fhbwiki/images/gnuplot/c8cb7945fb489f395f19d969e165c150.png.tmp) [function.fopen]: failed to open stream: No such file or directory in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 63 Warning: fwrite: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 67 Warning: fwrite: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 70 Warning: fwrite: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 83 Warning: fwrite: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 87 Warning: fclose: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 88 Warning: unlink(/opt/lampp/htdocs/_fhbwiki/images/gnuplot/c8cb7945fb489f395f19d969e165c150.png.tmp) [function.unlink]: No such file or directory in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 95 Warning: mkdir [function.mkdir]: Permission denied in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 51 Warning: chmod [function.chmod]: No such file or directory in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 52 Warning: fopen(/opt/lampp/htdocs/_fhbwiki/images/gnuplot/8ca75829c0e4cfa36d1add1ebac8a04a.png.tmp) [function.fopen]: failed to open stream: No such file or directory in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 63 Warning: fwrite: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 67 Warning: fwrite: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 70 Warning: fwrite: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 83 Warning: fwrite: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 87 Warning: fclose: supplied argument is not a valid stream resource in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 88 Warning: unlink(/opt/lampp/htdocs/_fhbwiki/images/gnuplot/8ca75829c0e4cfa36d1add1ebac8a04a.png.tmp) [function.unlink]: No such file or directory in /opt/lampp/htdocs/_fhbwiki/extensions/Gnuplot.php on line 95

I installed the newest version of the extension from the SVN-directory. I also installed the GnuPlot-Extension and checked its file-content, everything seems fine to me. I didn't reinstall GnuPlot itself as it lives outside the MediaWiki-directory, but there seems to be a permission-problem that did not occur with MediaWiki 1.10.0.

I'm not sure if my request shouldn't rather be posted on the GnuPlot-Extension page, but as I only use GnuPlot in connection with this extension I hope to find help here.

Thanks! --Katwol 14:04, 18 January 2008 (UTC)


 * Unfortunately, this is 100% related to GnuPlot extension. You are going to have to ask the authors of that extension for help. But it looks like all of the problems stem from . if you can figure out how upgrading MediaWiki made changed your permissions to cause this problem, the rest should go away. --Gri6507 16:42, 21 January 2008 (UTC)


 * Thanks for the tipp - after taking a closer look at the code in gnuplot.php I figured out the cause of the problem: I'd forgotten to create a gnuplot-directory in my $wguploaddirectory and set the userrights for that directory to 777. No everything works fine! :-)

Date selection won't work
Hi again,

another problem I get after upgrading from MediaWiki 1.10.0 to MediaWiki 1.11.0 is that the select-link for entering the start- and end-dates doesn't work anymore. :-( When clicking on the link nothing happens...

--Katwol 14:08, 18 January 2008 (UTC)


 * This is odd. The code to generate the calendars is plain old JavaScript. Are you sure your browser wasn't changed to disallow JS? When you view the source for the wiki page once it's loaded, do you see the large gobs of Javascript? --Gri6507 16:44, 21 January 2008 (UTC)


 * I've compared the current (downloadable svn-) version of SpecialUserStats_body.php with the working one from my productive wiki-installation and found the cause of the problem: there are quite a lot of line breaks in the current version that shouldn't be there - after I simply deleted those line breaks and the code in question was in one line again the calendar opens as wished. :-)


 * There is also a ?> missing at the end of the file, but adding just that makes no difference to the calendars.


 * Should/could I sent you the working version of the file (and how) or will you take care of it yourself?

Tranlation to German
Hi,

I've tried my hand at a translation to German (even though I had to deactivate the extension on our wiki due to concerns about data privacy):

--Katwol 14:29, 18 January 2008 (UTC)


 * Some corretions added - now it should be usable directly from this page. --Katwol 08:36, 22 January 2008 (UTC)

Making the Usage Statistics anonymous
Hi,

as I said in my earlier post, I cannot use this extion in our wiki anymore, because of concerns about data privacy.

The problem is, that this wiki is used in a workplace-environment and it is not wanted/legally allowed to be able to monitor what any single member of staff is doing. By showing the list of data for all users this extension is doing exactly that.

If there were a possibility to make the list anonymous or suppress it (or at least the data for users who are not the logged-in-user), I would ceartainly like to use this extension again.

Thanks!

--Katwol 14:38, 18 January 2008 (UTC)


 * I think that this feature already exists. The complete listing for the entire wiki are only available for the users with DELETE priviledges (typically only the sysops have that). If you try to view the same page when logged in as a regular user, the only thing you'll see are your own statistics and no one else's. --Gri6507 16:45, 21 January 2008 (UTC)


 * You're right, of course - I guess I have to learn to try out new features with another user with less privileges than my own. ;-)


 * --Katwol 07:57, 22 January 2008 (UTC)

Translation of selectable parameters
Hi,

after adding my own German translation to SpecialUserStats.i18n.php I noticed that there are a few places/words that should be translated/translatable as well:


 * the selectable parameters for intervall (e.g. Day, Week, Month)
 * the selectable parameters for type (e.g. Cumulative, Incremental)
 * the linktext for activating the calendar (e.g. select)
