Mewiki 1.22.5 very slow from external network

Hello,

I tried to find on internet a solution for the mediawiki i installed, but i can not find solution for. From local network is the mediawiki serving pages normal, bu from external network it is very slow. It takes more than 3 minutes to view, edit or save every page. Once it shown pages, the pages does not have layout, no images is shown, it seems like a old .txt page, without Gui Server running: Mediakiwiki: 1.22.5 PHP: 5.3.2 (Apache2handler) Mysql: 5.6.19

Could someone help me please.

Thanks in advanced

Beste regards,

Jee

The problem that no layout is shown usually is a problem with access to load.php. See Manual:Load.php for the most likely solution to this part!

As for the speed problem I am currently more or less clueless. When - from an external network - you request a static .html file: Is that file delivered quickly or is also delivering static files slow?

[SOLVED] Can't Login due Short-URL

Edited by 2 users.
Last edit: 09:47, 1 August 2014

Hello Guys, I installed MediaWiki (1.23) in a Subdomain (http://wiki.prefixaut.net). It's in the wiki-Folder (http://www.prefixaut.net/wiki - Will redirect you to wiki-Subdomain). So after I have struggled for a while to get Short-URLs to work, I can't login. When I click on the Log in button, I get redirected and it tries to show me the index.php Wiki-Page.

To get it working on the Subdomain I tried everything till I REMOVED everything which could cause problems, so the .htaccess file in the /wiki folder is empty and the LocalSettings.php is the default one which MediaWiki generated from the Install.

I hope you can help me, thanks in advance.

Prefixaut (talk)07:04, 1 August 2014

Hello! And wiki.prefixauth.net points to what? The wiki/ folder? What you configured for $wgScriptPath?

Florianschmidtwelzow (talk)08:13, 1 August 2014

As mentioned before: "It's in the wiki-Folder (http://www.prefixaut.net/wiki - Will redirect you to wiki-Subdomain)."

$wgScriptPath = "/wiki";

Prefixaut (talk)09:35, 1 August 2014

Yes, i know, but when your wiki subdomain's documentroot is the wiki folder itself, then your script path is simply false. Change it and the login will work...

Florianschmidtwelzow (talk)10:21, 1 August 2014

Thanks Florian and also thanks to Ciencia, changed booth Settings and works now :)

Prefixaut (talk)10:50, 1 August 2014
 
 
 

You have:

Article path       /$1
Script path     /wiki
index.php       /wiki/index.php
api.php /wiki/api.php
load.php        /wiki/load.php

That's a very bad idea, because if anything from the domain name will be a title of a page, all access to scripts (namely, /wiki/index.php) will be treated as accessing the article named wiki/index.php

You should rethink your URL scheme. Please read the recommendations again in Manual:Short_URL

Reducing the size of mediawiki database

MediaWiki 1.19.9 PHP 5.3.10 MySQL 5.5.37

I have a mediawiki site which has a very large database size ( 11 GB) . I want to deploy the site onto a development server. But the development server has limited resources like disk space. So I want to reduce the size of the database to 200MB.

I tried a couple of things 1. i ran the deleteBatch.php and deleted 80% of the pages and categories in my wiki 2. I ran deleteOldRevisions.php --delete and deleted all old revisions

Earlier the size of my database was 11GB and now its only reduced to 9.5 GB which is really strange.

Can anyone tell me what am I missing here? Or whether there is a better way to reduce the size of the database? I am aware of compressing the text to reduce table sizes, but I do not wish to compress the text.

Ys, Arnab

109.133.131.8408:18, 1 August 2014

You should try to get the size of each table from the database, to look at what of them are consuming most of the space.

New install with XAMPP on Win 2012 - cannot access wiki remotely

I have a brand new install, can access the wiki on the localhost, but cannot from other systems. I can browse to the host itself, proving apache is working, but when attempting to access the wiki firefox complains with:

Firefox can't establish a connection to the server at localhost

I have modified httpd and httpd-xampp conf files to change the server name and allow from all access. This appears to be a config issue with the wiki but I can't figure out where.

Any and all help is appreciated.

4.68.92.6823:40, 31 July 2014

You should set Manual:$wgServer to the public IP address or host name, accessible from all machines. It may be "localhost" now, which is a special hostname pointing to your own machine.

extension MathJax math formula not displayed

I work with mediawiki 1.23 and the extension MathJax is installed and required into my local setting

  In one page is written this formula ː  blabla....... \[(a+b)^3=(a+b)(a+b)^2\] blabla...
  OK ː If I am connect as wikiSysop the display is correct (about 3 lines as
       blabla.....
              the formula with the correct exposant in the middle of the line
       blabla.....
  NOK ː if I am not connected (anonymous) or connect as another user (chantoune)
        The display shows the syntax as written when I am in page edit

To solve this NOK case ː I have to install also the Extension Math (1465 files ǃǃadd ) and just add the line requiring Math in my local setting (no texvc compilation and so on.....)

So now, when I am not connected or connected as chantoune ː the display is correct (3 lines)

Is there a more simple solution ?
with for instance a specific $wgGroupPermissions['*'] to set ?

Why when I am wikiSysop connected, the extension Math is not mandatory to have a correct display ?
and why is it mandatory in other case ?

Chantoune (talk)15:43, 31 July 2014

No, there does not seem to be another solution - at least not right now. MathJax is used in combination with the Math extension. Extension:MathJax has more information on the current state.

88.130.83.23716:14, 31 July 2014
 

The difference between being logged as sysop or not may be that you have set something different in your preferences that allows rendering math, and that's different from the default value.

How to create a bot to add a new section in a talk page?

Edited by 2 users.
Last edit: 16:04, 31 July 2014

Hi there,

We are a group of researchers, trying to find a practical way to motivate professors and researchers who have published a fair number of research papers, to review Wikipedia pages and improve them.

As they do not usually have enough time to edit Wikipedia pages, we are trying to ask their comments on their interested pages, and post those comments to the corresponding talk pages, which can potentially help active Wikipedians on those pages to take advantage of experts' feedback and apply them as they like to the main article.

To this end, we need to implement a bot which posts experts' feedback as new sections on Talk pages.

As a matter of efficiency, we prefer to use python HTTP POST requests using MediaWiki API rather than available MediaWiki libraries.

We have not requested for an approval for the bot, and we are just trying to implement a trial version to test the bot on our own Talk pages.

For this purpose, I went through the following steps:

1- As discussed at https://en.wikipedia.org/wiki/Wikipedia:Creating_a_bot: >Create an account for your bot. Click here when logged in to create the account, linking it to yours. (If you do not create the bot account while logged in, it is likely to be blocked as a possible sockpuppet or unauthorised bot until you verify ownership)

>Create a user page for your bot. Your bot's edits must not be made under your own account. Your bot will need its own account with its own username and password.

So, I logged in to my own Wikipedia account, and created a new account (for the bot).

2- As discussed at https://www.mediawiki.org/wiki/API:Login: Logging in through the API requires two requests. For the first request, I wrote the following code in python:

   def logInRequestToWikipedia():
   
       # Add required parameters to the request.
       request = { 'action' : 'login' }
       request['lgname'] = 'BotName'
       request['lgpassword'] = '*************'
   
       url = 'https://en.wikipedia.org/w/api.php'
   
       headers = { 'content-type' : 'application/x-www-form-urlencoded' }
   
       r = requests.post(url, data = json.dumps(request), headers=headers)

The response starts with an error as follows:

   <error code="help" info="" xml:space="preserve">

And continues with the API documentation.

3- As discussed at https://www.mediawiki.org/wiki/API:Edit_-_Create%26Edit_pages:

>Note: In this example, all parameters are passed in a GET request just for the sake of simplicity. However, action=edit requires POST requests; GET requests will cause an error. Do not forget to set the Content-Type header of your request to application/x-www-form-urlencoded. The token that you received is terminated with +\\, this needs to be urlencoded (so it will end with %2B%5C) before it is passed back.

I added each of the following parameters separately and both together in the request data and tried all three cases, but it returns the same response.

   request['lgtoken'] = '%2B%5C'
   request['Content-Type'] = 'application/x-www-form-urlencoded'

4- Also I tried each of the followings in my request data, but it returns the same response:

   request['format'] = 'json'
   request['format'] = 'xml'

Do you think the problem can be related to the fact that we have not requested for an approval for the bot yet? Because we are just trying to implement a trial version to test the bot on our own Talk pages, and apply for the approval after making sure everything will work.

I will appreciate it if you help us with this issue.

Best regards.

PostOnTalk (talk)17:01, 29 July 2014

Apparently, you shouldn't use data = json.dumps(request) in requests.post

While you want a JSON response, that doesn't mean that you need to pass data to MediaWiki in JSON format!

Try using this instead, by just passing the dictionary without further encoding:

      r = requests.post(url, data = request, headers=headers)

http://docs.python-requests.org/en/latest/user/quickstart/#more-complicated-post-requests

Ciencia Al Poder (talk)09:33, 1 August 2014

Also note that, after logging in, you should save the cookies and send them back again on every other request, because cookies contain the session token to maintain you logged in. I don't know if python would do this automatically for you, so be sure to check this.

Hello All,

I am having a hard time to find out if the new MediaWiki 1.23.2 supports the Visual Editor. we are using Visual Editor on previous versions and we really need that so I was looking for information about the new media wiki version and the Visual Editor. Is it possible to use Visual Editor with the new Version? Where can I check information about this?

Thanks in advance! LonelyRider82

problems to migrate from Mediawiki 1.17.0 to 1.23.2 under Windows

Hi all,

I am having problems to migrate from Mediawiki 1.17.0 to 1.23.2 under Windows. I am following the instructions in in http://www.mediawiki.org/wiki/Manual:Upgrading. I reached the chapter "Run the update script" and:

The call "php update.php" simply does nothing.

My php installation seems to be ok, a call like "php info.php" runs fine.

  • OS: Windows Server 2003
  • PHP version: 5.3.8
  • MySQL version: 5.1.45


Thank you Hartmut

87.139.247.23013:27, 31 July 2014

What you mean with nothing? Is there _no_ output?

Florianschmidtwelzow (talk)13:55, 31 July 2014

right. 'php update.php' returns immediatly with no output.

Hartmut

87.139.247.23015:15, 31 July 2014

Hmm, have you changed the value of error_reporting in your php.ini (for the cli, not for webserver!)? Can you try to run the update from the webinstaller (make a backup!!!)?

time ParserFunction gives unexpected output

On the afternoon of July 31, 2014 I noticed the following behaviour:

 {{#time:Y-m}} => 2014-07
 {{#time:Y-m|now -1 months}} => 2014-07  (<-same month?)
 {{#time:Y-m|now -2 months}} => 2014-05


By Aug 1st, the same functions yield as expected:

{{#time:Y-m}} => 2014-08
 {{#time:Y-m|now -1 months}} => 2014-07
 {{#time:Y-m|now -2 months}} => 2014-06 

Am I just using the function wrong? Tried it on my mediawiki.org talk page too with the same result. Are adjustments by month not doing what I think? Thanks!

Lbillett (talk)03:03, 1 August 2014

Maybe i's possible, that you refer to your local time zone? The time parser function uses the server time (or a configured time in LocalSettings.php), so it's possible, that the server was in August and "you was still in July"? Just an idea :)

Using 'OR' operator in queries

Simple questions, hopefully a simple solution.

Basically, 'real' SQL queries allow you to do this:
.WHERE 'foo' = 'pi' OR 'bar' = 'pi'

Doing the same in 'Mediawiki style' isn't quite as apparent, though. It seems to only be known how to use the AND operator, like so:

'foo' => 'pi',
'bar' => 'pi'

...With the above example being equivalent to:

WHERE 'foo' = 'pi' AND 'bar' = 'pi'

In the simpleest of terms: How can I uss the 'OR' operator in a query while staying true to the 'wiki' style? I guess I could use the query() function (As opposed to delete(), select(), update(), write() and so forth), but the rest of my queries are 'wiki' style and I prefer for things to remain uniform.

Thanks, if you happen to have the answer.

173.217.255.8105:33, 1 August 2014

Conditions in Database access layer's select are always connected with AND (like the documentation to this function say: https://doc.wikimedia.org/mediawiki-core/master/php/html/classDatabaseBase.html#a76f9e6cb7b145a3d9020baebf94b499e

If you want to use OR; you can specify the conditions as a string, like (edited example from Manual:Database_access):

$res = $dbr->select(
	'category',                                   // $table
	array( 'cat_title', 'cat_pages' ),            // $vars (columns of the table)
	'( cat_pages > 0 ) OR ( cat_pages = 1 )',     // $conds combined with OR
	__METHOD__,                                   // $fname = 'Database::select',
	array( 'ORDER BY' => 'cat_title ASC' )        // $options = array()
);

But: Maybe you can consider to remove the OR condition if possible, sometimes it ive a way to get the same result with only one condition or with and connected conditions.

Another way that should work is to use DatabaseBase::makeList(). I haven't tested it, but you can define a new var and use this as a condition string (makeList() returns a string), example:

$conds = array(
   'cat_pages > 0',
   'cat_pages' => 1
);
$res = $dbr->select(
	'category',                                   // $table
	array( 'cat_title', 'cat_pages' ),            // $vars (columns of the table)
	$dbr->makeList( $conds, LIST_OR ),            // $conds combined with OR
	__METHOD__,                                   // $fname = 'Database::select',
	array( 'ORDER BY' => 'cat_title ASC' )        // $options = array()
);

Patch from 1.23.1 to 1.23.2 Error

I'm having exactly the same problem, no test folder. 'can't find file to patch at input line 276'

Does this seem to you like it's not breaking any needed functionality?

204.90.74.713:52, 31 July 2014

The errors are all related to files in the folder tests/. This folder is not needed for MediaWiki to run; it is not present in the 1.23.x tarballs. Until the patch file has been fixed, you can just run the "broken" patch file and remove the .rej files, which it leaves behind. Afterwards you have a correctly updated installation - exactly what you should have!

best practice to import Templates (Wikipedia Style Cite Web , german Internetquelle)

Edited by another user.
Last edit: 14:40, 30 July 2014

Hello,

i have installed a brandnew 1.23.1 in a corporate environment. In Order to organize external web links i have activated Extension:Cite which is also running fine. However, neither the english wikipedia´s Template:Cite_Web nor the german Vorlage:Internetquelle is in my Wiki which i´d like to format external weblinks. Ich could now create the template and all depedencies manually by cut/copy/paste from some other sites. However, export (Special:Export/Template: ) doesn´t seem to work on Template: and Vorlage: , and import into these area also seems to be blocked. Is there a smart way to copy all those templates from another page ? Best would be repetitive job keeping my wiki in line with some other in terms of Templates and formatting.

Export of Templates (german Vorlagen) is possible ;) Just request https://de.wikipedia.org/wiki/Spezial:Exportieren (german wikipedia) and type in "Vorlage:Internetquelle". If you want to have full dependencies, click "Inklusive Vorlagen" before click "Seiten exportieren". After this you become an export XML file which you can import simply in your wiki with Special:Import (german Spezial:Importieren").

[RESOLVED] Changes affecting InstantCommons function?

Has anything changed in the way Commons feeds to an outside Wiki? All the pictures disappeared from our wiki on Saturday 31 May 2014, with no change in programming (and the host denies changing or limiting anything). All the pictures other than the site's logo are from Commons (and we encourage our users to develop that resource).

It's been so long I can't remember which MediaWiki version we use.

Hogweard (talk)11:02, 2 June 2014

You use MediaWiki 1.15.4 (http://wikishire.co.uk/wiki/Special:Version), i would say: Update soon ;)

InstantCommons works like before (if i'm right, tested with MW 1.24wmf2). Be sure, that you set $wgUseInstantCommons to true.

Florianschmidtwelzow (talk)11:55, 2 June 2014

And after upgrading please run the update.php ether in the web updater or in ssh please. By going to here http://wikishire.co.uk/mw-config for the web updater.

5.66.153.13515:18, 2 June 2014

And you can uninstall the stringfunction extension because some of it was merged into ParserFunctions extension

And to enable the integrated string function in parser function just add this to LocalSettings.php

$wgPFEnableStringFunctions = true;

And please also add

$wgUpgradeKey = 'set-me-to-some-random-string';

This to LocalSettings.php but please do change upgrade key to something else that no one else knows.

Can't delete image uploads. "Error deleting file: Could not create directory 'mwstore://local-backend/local-deleted/a/x/b'."

Edited by author.
Last edit: 16:02, 29 July 2014

Product Version
MediaWiki 1.23.1
PHP 5.5.9-1ubuntu4.3 (apache2handler)
MySQL 5.5.38-0ubuntu0.14.04.1

Ubuntu Server is running on a Virtual Machine. My /var/www/html/mediawiki/images directory is mounted to my storage drive as the boot drive is only for the OS. The Wiki is private.

LocalSettings.php does not have $wgUploadDirectory or $wgUploadPath set, so those are the default. $wgDeletedDirectory is a mount on another file server which has the same permissions as the images directory. 755 & www-data as both owner & group.

Directory: /var/www/html/mediawiki/images (mounted to a different drive than the rest of /var/www/html/mediawiki) /mnt/fileserver/deletedwikifiles

php.ini has file_uploads set to on and my version means that safe_mode isn't the issue. I read about a bug regarding upgrading MediaWiki from 1.22 to 1.23 causing file uploads to be broken, but that was traced back to shared hosts and this server isn't shared.

Any help is appreciated.

Edit:

I just thought I'd bump this with a bit more technical information. I couldn't delete files, but I could upload them. Then I did the following commands from the root of MediaWiki:

sudo chmod 775 -R ./ [Entire MediaWiki Root has rwxrwxr-x permission set.]
sudo chmod 666 -R ./images [images * subdirectories has rw-rw-rw- permission set.]
sudo chmod 775 ./images [The directory images has rwxrwxr-x permission set.]
sudo chown root:www-data -R ./ [This means Root has full rwx for everything but files in images where it has rw- only while apache web group has rw- for images, but not the directory, and rwx for the rest of MediaWiki's root.]

Then I could delete the files, but when I tried to upload them, I got this error: 'Could not create directory "mwstore://local-backend/local-public/b/b9".' and the thumbnails were broken.

Then I did this command from the same root directory of MediaWiki:

sudo chmod 777 -R ./ [Everything has all the permission for MediaWiki's root directory.]

And once again, I can upload files, and see thumbnails/files, but I can't delete them again, getting 'Error deleting file: Could not create directory "mwstore://local-backend/local-deleted/8/d/b".' when I try.

I'm baffled as to how to troubleshoot what appears to be a permissions problem in this situation after those results.

TremorAcePV (talk)16:39, 28 July 2014

Can you check if the directory specified in Manual:$wgDeletedDirectory exist and is writeable from the webserver?

Florianschmidtwelzow (talk)08:52, 29 July 2014

I figured you might be on to something there because I did the following:

ls -la /mnt/fileserver/deletedwikifiles
drwxrwxrwx  4 root root 4096 Jul 29 10:09 .
drwxrwxrwx  4 root root 4096 Jul 29 10:09 public
drwxrwxrwx  4 root root 4096 Jul 29 10:09 private

So I checked and I hadn't configured /etc/fstab to mount the drive such that www-data is owner/group because it's on an NTFS volume (which means it makes root owner/user by default). I tried redefining $wgDeletedDirectory = $wgScriptPath/images/deleted as a test.

ls -la ./images/deleted

drwxrwxrwx  4 www-data www-data 4096 Jul 29 10:09 .
drwxr-xr-x 14 www-data www-data 4096 Jul 29 09:39 ..
drwxrwxrwx  2 www-data www-data 4096 Jul 29 10:08 private
drwxrwxrwx  2 www-data www-data 4096 Jul 29 10:09 public

Yet it still gives the "Creating directory" error when trying to delete a file. I tried changing the above permissions to 755 (rwxr-xr-x), just like it is for the rest of ./images, but that didn't fix it either.

TremorAcePV (talk)15:28, 29 July 2014

You may try creating the directory from the shell, directly, but as the webserver's account, using the sudo command.

If it succeeds, you may also set a debug log to see exactly the full path it's trying to access.

Ciencia Al Poder (talk)09:25, 31 July 2014
 
 

Note that this command will render your image folders inaccessible:

sudo chmod 666 -R ./images [images * subdirectories has rw-rw-rw- permission set.]

Directories need the execute permission set to be accessible.

Setting 777 for uploaded files is also not recommended.

The recommended way to set such permissions is to use the find command:

find ./images -type d -exec chmod 755 {} \;
find ./images -type f -exec chmod 644 {} \;

Depending on who's the owner of those files, permissions may vary from 777/666 for debugging or even 700/600 for strict permissions on shared hosts.

Ciencia Al Poder (talk)09:48, 29 July 2014

That's good to know.

Of course. That was a test to see if I could access them correctly. A test to see if permissions is the problem.

With these permissions, set exactly how you have them written there, I cannot upload or delete files. That's the first time this result has happened. I get both errors:

Could not create directory "mwstore://local-backend/local-public/2/26".
Error deleting file: Could not create directory "mwstore://local-backend/local-deleted/8/d/b".

I figured it might be because I had done this before that:

sudo chown root:www-data ./images

So I tried changing it to this:

sudo chown www-data:www-data ./images

And that let me upload files. Found the culprit there.

Check my response to Florianschmidtwelzow above if you want to know about the deleting files error.
