Post a new question

1. To help us answer your questions, please indicate which versions you are using, as found on your wiki's Special:Version page:
   • MediaWiki version
   • PHP version
   • Database type and version
2. Please include the web address (URL) to your wiki if possible. It's often easier for us to identify the source of the problem if we can see the error directly.

I have an extension which defines a style file, places it into an extension bundle and does an $out->addModules in an onOutputPageBeforeHtml hook.

Unfortunately I get a flash of unstyled content (FOUC) affecting the class specifications.

I tried to put the style into Common.css - just the same problem.

My current workaround is to use $out->addHtml to inject a style tag containing the class definitions - but, of course, this is not really nice software engineering. Another workign workaround is to hardcode the style as part of the HTML tags. This is even less nice.

What is the best practice of adding css so that I get no FOUC?=

This section should explain the requirements. To summarize, you'll need to create a separate resource loader module with the styles in them, and load that through $out->addModuleStyles.

Thnx. Works.

Hi, I am facing some issues with infoboxes on my own wiki.

I am under the impression I have installed every infobox template available (that I have in use) and therefore I cannot account for the difference in formatting.

As an example, please see this infobox on my page on my personal wiki:

https://www.encyclopediabritannia.org/index.php?title=German_Canadians

Now compare this to the wikipedia version:

https://en.wikipedia.org/wiki/German_Canadians

As you can see, the formatting is very different. The wikipedia infobox is centred, and the text wraps, yet mine does not. The text makes the width of the infobox wider, when it should not.

This also happens on the infobox template itself.

Here is the template on my wiki:

https://www.encyclopediabritannia.org/index.php?title=Template:Infobox#Examples

Here is the template on wikipedia:

https://en.wikipedia.org/wiki/Template:Infobox#Examples

Again, the formatting on the template itself seems to be broken. I am not sure why this happens, but the formatting is broken and therefore *every* infobox on my wiki is broken.

Can anyone shed some light on this for me?

Thank you!

Edit 1: I have fixed the earlier issue, the Apache server was broken by an automated script. The above problem still exists though!

They have in w:en:MediaWiki:Common.css at .infobox a specification width: 22em; controlling The text makes the width of the infobox wider, when it should not. Maybe more interesting things.

https://www.encyclopediabritannia.org/index.php?title=MediaWiki:Common.css did not yet, but that selector is already present.

I have done it, THANK YOU! You are fantastic !

Thanks for your help!

I cannot edit the common.css page on my own wiki, I want to make it a mirror of that on mediawiki/wikipedia but I cannot edit it

Do you know how I can give myself permissions? I am the only admin

For modification of site CSS or JavaScript you need to be interface admin and as site maintainer you should be able to assign yourself to that group. The same way you made your account to be general admin (sysop group).

You are amazing, thank you!

I just installed mediawiki 1.35 every time I edit with the visual editor, when I save changes, I get error 415 and I don't know what happens, what can I do?

Check your access log and tell us what lines you see there for rest.php.

i can't obtain access of the logs of the visualeditor, my wiki is alojed in host shared

i check yhis mistake of the file rest.php

{"messageTranslations":{"es":"La ruta relativa solicitada () no coincide con ningún controlador conocido","en":"The requested relative path () did not match any known handler"},"httpCode":404,"httpReason":"Not Found"}

How was that generated? And, it looks like VE is not set up correctly. How did you install it?

that was installed with the mediawiki installation

Can you add the following to your LocalSettings.php:

$logDir = "$IP/cache";
$wgDebugLogGroups['rest'] = "$logDir/rest.php";

(Change $logDir to something the webserver can write to, if needed.) And apply the following diff:

(If you don't know what I mean by "apply the following diff", let me know and I'll try to guide you through it.)

After that, you should get messages in your rest.log file (the one you will have told MediaWiki to log requests to with your LocalSettings.php modifications) which should begin to give us an idea of what is happening.

ok, i add the lines a localsentigs.php i don't undernstand "aplic the next diference " the file rest.log where to consult?

Nevermind the diff. Just put replace includes/Rest/EntryPoint.php in your mediawiki installation with this file. After that, try to use the VE. A log file should show up under cache/rest.log on your shared hosing site.

So.... I have some logs from earlier this month that show the 415 responses like you're getting here, ... and I can't figure out what I did to get rid of them.

so, that registers are solutions for this problem?

There are. ping me here tomorrow and I'll ask you for some more debugging info that might help.

good morning, According to everything, we agree that there is a solution, I hope it works, well then what remains to be done?

Could you replace the files under extensions/VisualEditor with the following:

• includes/ApiParsoidTrait.php
• includes/ApiVisualEditorEdit.php
• includes/VEParsoid/src/Rest/Handler/ParsoidHandler.php
• includes/VEParsoid/src/Rest/Handler/TransformHandler.php

Then remove your old rest.log that you posted yesterday and then try the editing again. Assuming it won't work (I don't know why it would), please share what is in your rest.log, then.

Thank you. One more file. In mediawiki: includes/Rest/Validator/Validator.php

Then remove the rest log and re-do the edit test as before. This time, though, look for the section in your rest.log that begins "validateBody got headers: " and paste only that section.

I just tested the visual editor and it still doesn't work, replace the above code in the rest.php file and it remains the same

The last result you posted contained a line that looked like this:

   'content-type' => 'application/json',
   'via' => '1.1 alproxy',

The via seems to indicate that you are using a proxy server and it may be caching and/or changing your headers. Can you remove the proxy?

ok, these lines have been eliminated, i don't see any results

What do you mean by "these lines"?

Did you delete the old rest.log and use the includes/Rest/Validator/Validator.php replacement for the corresponding MediaWiki file that I pasted to generate a new rest.log?

yes, I deleted the old rest, the new one removed the proxy lines and also added the "replacement of validateboy", the validator file, php, is also already modified

Could you humor me and post the new rest.log?

This is the part I was looking for:

2020-10-21 16:48:32 http7 pony_mediawiki-wiki: validateBody got headers: array (
  'Connection' => 
  array (
    0 => 'close',
  ),
  'X-Ssl-Client-Verify' => 
  array (
    0 => 'NONE',
  ),
  'X-Ssl' => 
  array (
    0 => '1',
  ),
  'X-Forwarded-Proto' => 
  array (
    0 => 'https',
  ),
  'Via' => 
  array (
    0 => '1.1 alproxy',
  ),
  'Api-User-Agent' => 
  array (
    0 => 'VisualEditor-MediaWiki/1.35.0',
  ),
  'User-Agent' => 
  array (
    0 => 'VisualEditor-MediaWiki/1.35.0',
  ),
  'Accept-Language' => 
  array (
    0 => 'es',
  ),
  'Accept' => 
  array (
    0 => 'text/html; charset=utf-8; profile="https://www.mediawiki.org/wiki/Specs/HTML/2.0.0"',
  ),
  'Host' => 
  array (
    0 => 'lapluma.tk',
  ),
)

You can see that MediaWiki (Api-User-Agent) is going through the proxy (Via) and that the headers do not include Content-Type.

Do you have $wgHTTPProxy set?

the proxyhttp i don't know, i don't know how configure that.

that code should it be removed or added?

I thought you might be using and that might be causing the problem.

The problem apprears to be that mediawiki is somehow using a proxy when it should not be and that proxy appears to be filtering out some headers that Parsoid or VE expects.

Beyond that, I don't know what I can tell you since I'm not familiar with how your MediaWiki, php, or server is configured.

ok i understand, visualeditor i think that is the configuration predeterm and i don't if exist how change that

my server is in alwaysdata is shared, these are my dates of software in the wiki, That would be solved although I don't know how it is

It looks like you are using the developers instructions which the VE page says:

What happens if you remove everything after #Add more configuration options below. except

$logDir = "$IP/cache";
$wgDebugLogGroups['rest'] = "$logDir/rest.log";

that don't help, because i preview I tried it and it kept marking the error

what instrucctions i should revise for the visualeditor normally?

Even if you tried it previously, you should try it again now that we have the rest.log recording problems. It may tell us something new.

No new information, that I could see. Could you try this updated version of includes/Rest/Validator/Validator.php for mediawiki? I commented out the line causing it to return 415.

It will probably still fail, but the failure will be interesting.

the changes are diferent

Well, you are getting farther. I would suggest filing a bug at this point giving as much information as you have. Something is going on with the proxy and I do not know how to fix it.

@MarkAHershberger, something strange that I realized is that when I use http the visual editor does work but when I use https (ssl) the visual editor marks this error when saving the edition

Interesting... Change $wgServer to https and see if it works for https edits then.

If it does, then just make the webserver redirect all requests to https.

sorry i meant, the visualeditor 100 % working in url http but in https (ssl) does't work and places this mistake before save the changes

I had the same error here and, despite of the HTTPS redirects, at the end was the lack of "https" in my $wgServer .

I've notice this by the JSON response of the 415 error message (using inspect).

I've also changfe the $response['code'] to print_r($response,true) to get the full error data.

./VisualEditor/includes/ApiParsoidTrait.php:                [ 'apierror-visualeditor-docserver-http', $response['code'] ]

Experienced same issue, and it was resolved by changing url of website in $wgServer from http to https. Thanks for the hints.

Hello, thankful for all of the efforts and details in this thread! As simple as this may sound, the culprit that I found was semicolon characters in the content ¯\_(ツ)_/¯

I'm running a new installation of MediaWiki 1.35 and I can reproduce this issue just by adding a semicolon to my text in the Visual Editor. When I leave out semicolons, no issue.

Hi

I tried to enable SyntaxHighlight on my newly installed Wiki, running inside XAMPP 8.0.6 on Windows 10 Version 2004, 64bit.

Attempt 1: Using the incorporated pygmentize

Firtstly I had to rename "pygmentize" to "pygmentize.pyc" and add the following line to LocalSettings.php:

$wgPygmentizePath = 'D:/xampp/htdocs/mywiki/extensions/SyntaxHighlight_GeSHi/pygments/pygmentize.pyc';

When I edit a page with syntaxhighlight, the following messages are logged in the wiki logfile:

[Called from SyntaxHighlight::{closure} in D:\xampp\htdocs\mywiki\extensions\SyntaxHighlight_GeSHi\includes\SyntaxHighlight.php at line 293]
[exec] Executing: cmd /s /c ""D:/xampp/htdocs/mywiki/extensions/SyntaxHighlight_GeSHi/pygments/pygmentize.pyc" "-l" "php" "-f" "html" "-O" "cssclass=mw-highlight,encoding=utf-8,startinline=1""
[exec] Error running cmd /s /c ""D:/xampp/htdocs/mywiki/extensions/SyntaxHighlight_GeSHi/pygments/pygmentize.pyc" "-l" "php" "-f" "html" "-O" "cssclass=mw-highlight,encoding=utf-8,startinline=1"": Zugriff verweigert

Zugriff verweigert means access denied

If I call the above command on the command line it works fine and delivers correct result (if you input some lines on the standard input):

D:\>cmd /s /c ""D:/xampp/htdocs/mywiki/extensions/SyntaxHighlight_GeSHi/pygments/pygmentize.pyc" "-l" "php" "-f" "html" "-O" "cssclass=mw-highlight,encoding=utf-8,startinline=1""
print "Hello";
^Z
<div class="mw-highlight"><pre><span></span><span class="k">print</span> <span class="s2">"Hello"</span><span class="p">;</span>
</pre></div>

D:\>

Attempt 2: Using external pygmentize.exe

I replaced the line in localsettings.php with:

$wgPygmentizePath = 'C:/Python39/Scripts/pygmentize.exe';

This time the following lines are logged:

[Called from SyntaxHighlight::{closure} in D:\xampp\htdocs\mywiki\extensions\SyntaxHighlight_GeSHi\includes\SyntaxHighlight.php at line 293]
[exec] Executing: cmd /s /c ""C:/Python39/Scripts/pygmentize.exe" "-l" "php" "-f" "html" "-O" "cssclass=mw-highlight,encoding=utf-8,startinline=1""
[exec] Error running cmd /s /c ""C:/Python39/Scripts/pygmentize.exe" "-l" "php" "-f" "html" "-O" "cssclass=mw-highlight,encoding=utf-8,startinline=1"": Fatal Python error: _Py_HashRandomization_Init: failed to get random numbers to initialize Python

According to this thread, the Environment variable SystemRoot must be set properly, otherwise the Win32 API call CryptAcquireContext will fail when called inside python during initialization. (quoted from above link).

On my system, SystemRoot is properly set, even inside the script D:\xampp\htdocs\mywiki\extensions\SyntaxHighlight_GeSHi\includes\SyntaxHighlight.php Maybe some security features prevent access to SystemRoot?

Again, when invoked on the command line it works fine:

D:\>cmd /s /c ""C:/lang/Python39/Scripts/pygmentize.exe" "-l" "php" "-f" "html" "-O" "cssclass=mw-highlight,encoding=utf-8,startinline=1""
echo "hello";
^Z
<div class="mw-highlight"><pre><span></span><span class="k">echo</span> <span class="s2">"hello"</span><span class="p">;</span>
</pre></div>

D:\>

Using:

• Window 10 Version 2004, 64bit
• XAMPP 8.0.6
• MediaWiki 1.36.0
• Python 3.9.5
• Pygments 2.9.0 (for the external attempt)

Hope this information is helpful to fix this issue.

I just discovered, that there is already a similar thread Migrating from 1.9.3 to 1.34 - Geshi no longer available.

I was using the Geshi extension o 1.9.3 with content like

<code xml>

...

    <customcerts

dir="certs"

    />

...

</code>

Now the Geshi extension is gone and I could use Extension:SyntaxHighlight. However, I have hundreds of pages using the <code ''lang''> tag instead of <syntaxhighlight lang="''lang''">. Is there a solution to that apart from manually editing all of them?

Thanks and Regards, Christoph

You can try making use of Extension:Replace Text.

Thanks for pointing me to Replace Text, @AhmadF.Cheema!

However, I do not get the extension to work on a Windows system:

syntaxhighlight uses Pygmentize directly (such as 'C:\...\SyntaxHighlight_GeSHi\includes/../pygments/pygmentize" "-l" "xml" "-f" "html" "-O" "cssclass"').

pygmentize is a script starting with "#!/usr/bin/env python3" which is going to work on *nix'ish systems fine but won't work on Windows. So I get an expection "PHP Notice: Failed to invoke Pygments" when the extensions tries to render a page.

I installed python 3.8 on the box which seems to run fine (at least, I can get a python prompt with now errors).

So as far as I am concerned, this won't ever work on Windows, does it?

Some googling yields a page saying you need to install ez_install.py and run it. I did so (downloading it from pypi.org) and it bails out saying "SSL required". So I edited it and changed the download URL from http to https.

Now it bails out saying "in self.chown(tarinfo, dirpath) TypeError: chown() missing 1 required positional argument: 'numeric_owner'".

It is frustrating :-|

Am I on the right track with getting ez_install to run?

Or is there a way to tell mediawiki to just call upon python.exe directly?

This SO answer seems to have a hint.

@MarkAHershberger you made my day - almost!

here it is in a nutshell:

      [ install python 3.8 ]

python -m ensurepip --default-pip

      python -m pip install --upgrade pip setuptools wheel

      easy_install Pygments

now there is a Windows pygmentize.exe in .../python/Scripts

set "$wgPygmentizePath = "C:/.../python/Scripts/pygmentize.exe"; in LocalSettings.php

I can run pygmentize from the shell.

But: although $wgPygmentizePath is set correctly, I keep getting

PHP Notice: fwrite(): write of 1597 bytes failed with errno=22 Invalid argument in C:\inetpub\wwwroot\wiki\mediawiki-1.34.0\includes\shell\Command.php on line 475

Apparently, proc_open in Command.php cannot start the executable.

Has anyone got SyntaxHighlight_GeSHi to work on a Windows/IIS system? (IIS 8.5, latest PHP 7) ?

You seem to have stumbled upon a windows-only bug. Can you get a stacktrace of the error? Try the following:

• $wgShowExceptionDetails Enable more details (like a stack trace) to be shown on the "Fatal error" page.
• $wgShowDebug Adds the "log messages" part of wgDebugToolbar as a raw list to the page.

@MarkAHershberger

[ I needed to shorten the trace cause mediwaiki was complaining about "Flow spam filter: large amount of consonant/vowel clusters" ]

I saw a note in PHP's doc for popen:

Example #2 proc_open() quirk on Windows

While one may expect the following program to search the file filename.txt for the text search and to print the results, it behaves rather differently.

<?php
$descriptorspec = [STDIN, STDOUT, STDOUT];
$cmd = '"findstr" "search" "filename.txt"';
$proc = proc_open($cmd, $descriptorspec, $pipes);
proc_close($proc);
?>

The above example will output:

'findstr" "search" "filename.txt' is not recognized as an internal or external command,
operable program or batch file.

To work around that behavior, it is usually sufficient to enclose the cmd in additional quotes:

$cmd = '""findstr" "search" "filename.txt""';

But I don't think its true. The symptom is exactly what I saw, however the solution doesn't work.

I finally got tired of this and sort of "fixed" it by changing the code in mediawiki-1.34.0\extensions\SyntaxHighlight_GeSHi\includes\SyntaxHighlight.php from

311 				$result = Shell::command(
312 					self::getPygmentizePath(),

320

322 					$ttl = WANObjectCache::TTL_UNCACHEABLE;
323 					$error = $result->getStderr();
324 					return null;
325 				}
326

                                if (false) {
                                    // debug, keep in/out put
                                    $ioo = "$filebase-o.txt";
                                    file_put_contents($ioo, $pyg);
                                } else {
                                    unlink($ioi);
                                }
                                return $pyg;

This is of course ugly to say the least but it works somehow and should be fine until a fix is there.

Let me add that I felt the Shell:: code to be overly complicated. However, I was perhaps just not fair cause it refused to work for me for so long ;-)

Many thanks! that worked for me. Greetings

This fix also worked for me on Windows. Thank you!

How can we get this issue logged and fixed in the production code?

I was just working on something similar, but now just made a copy&paste of your code and it works fine for me too, thanks.

PS: I too was overwhelmed by the complexity of Shell::code

It looks like this might be task T193613. Four months later, I don't know why I wrote this. It must be a typo.

I have the same problem too... So what you are saying is that this error should disappear with mw 1.35?

I'm not sure why I thought a stable interface policy would help. That must be a typo.

I have exactly the same problem.

So this bug is still present in version 1.35. I had to include the hack here (https://www.mediawiki.org/w/index.php?title=Topic:Vibz8ak3wnpu9mv8&topic_showPostId=viery0f4ta9jp35e#flow-post-viery0f4ta9jp35e) to get the extension to work in version 1.35.

How can i backup my mediawiki localsetting.php and the content of the mediawiki? the mediawiki runs on a NAS box, but this should not be a problem.

MediaWiki version 1.31

wie kann ich mein mediawiki localsetting.php und den Inhalt in regelmäßigen Abschnitten sichern? Das ganze läuft auf einer NAS Box mit der 1.31 Version, sollte aber kein Problem darstellen.

Does Manual:Backing up a wiki answer your question?

I have tables in multiple pages and want to create a new table (in a different page) that automatically lists all rows with matching value in one column.

Example page 1:

2020-12-31 | NBA | Celtics | Lakers

2020-12-31 | NFL | Bears | Packers

2020-12-31 | MLB | Yankees | Red Sox

2020-12-31 | NHL | Islanders | Rangers

2020-12-31 | MLB | Mets | Phillies

Example page 2 (auto-generated table based on matching value in column 2):

2020-12-31 | MLB | Yankees | Red Sox

2020-12-31 | MLB | Mets | Phillies

I would appreciate if someone can just point me to what script/function/extension I need for this and I'll read up on the details.

You probably need Extension:Cargo for that.

Is w:en:String-searching_algorithm possible with wiki? I need it to look for whether an input value given for a template contain the specific characters "[[" for wikilinking, so that the template can automatically remove extra brackets if they were manually added.

I am looking specifically for merging Clickable_buttons and similar templates that break with extra link brackets

Please consult Help:CirrusSearch for basic and advanced features.

No, I am looking for something like "w:en:Module:String". I think templates "Str find" and "Replace" would suffice

In this case you got the central point already.

I could recommend w:de:Wikipedia:Lua/Modul/WLink/en #getPlain which will have stripped off any link syntax.

However, you might fail to detect any {{ within template parameters since they have been resolved (expanded) already at the time the parameter value is passed to the receiving template. Supposed they have been properly balanced.

Ok, thanks

Installed MW 1.35/ SQL/ Server 2019.  Upgraded to BlueSpice.  BlueSpice came up.  Imported existing extensions/ modified the localsetting.php.  After SQL DB datadump import, the page errors out.

MediaWiki internal Error   …… DBQueryError …

I believe I need to run the update.php.

How do I run it exactly?

I try to install MediaWiki 1.36.0, and I receive this error:

MediaWiki 1.36 internal error

Installing some PHP extensions is required.

Required components

You are missing a required extension to PHP that MediaWiki requires to run. Please install:

• intl (more information)

What is unclear with the error message and its instructions?

What instructions? I have already installed MediaWiki 1.35.0 and 1.35.1, and I did not received this error.

As noted in the MediaWiki 1.36 upgrade notes, 1.36 and newer require the php intl extension. What instructions? "You are missing a required extension to PHP that MediaWiki requires to run. Please install: intl".

At https://www.php.net/intl there are only a lot of links. At https://www.php.net/manual/ro/intl.installation.php there is no step-by-step guide about from where to download the files and how to install.

Which exact operating system is running on that machine?

MediaWiki files are installed on my computer, that uses a version of Windows 10.

The problem is that I do not know how to install intl, and I do not understand how from https://www.php.net/intl.

What should I do in order to install intl? I really do not understand how from https://www.php.net/intl.

This is from my notes of setting up an Ubuntu 18.04 Digital Ocean VPS recently:

sudo apt install php-intl

I think after that you need:

sudo systemctl restart apache2

Similar issue here, intl is installed, but WikiMedia does not recognize it as such. Extension is enabled in php.ini, extension dir is set correctly, other extension prerequisites that wikimedia reported run fine, but intl does not.

Even though intl is installed, wikimedia reports the extension as missing. Does it need a default_locale?

intl

Internationalization support => enabled

ICU version => 68.1

ICU Data version => 68.1

ICU Unicode version => 13.0

Directive => Local Value => Master Value

intl.default_locale => no value => no value

intl.error_level => 2 => 2

intl.use_exceptions => Off => Off

check if its enabled on the webserver. Whether intl is enabled in commandline php is separate from if its enabled on the webserver.
