I am trying to write my very first MediaWiki extension and need some way to debug it. What is the simplest way to do it? Showing a message, logging into a file etc. would be fine. I just want to slowly progress over the code and see where it breaks and what the content of a variable is.
I've tried (from http://www.mediawiki.org/wiki/Manual:How_to_debug#Useful_debugging_functions)
// ...somewhere in your code
if ( true ) {
wfDebugLog( 'myext', 'Something is not right: ' . print_r( 'asdf', true ) );
}
in extensions/myext/myext.php and added to LocalSettings.php
require_once( 'extensions/myext/myext.php' );
# debugging on
$wgDebugLogGroups = array(
'myext' => 'extensions/myext/myextension.log'
);
but then my Wiki doesn't work at all (error 500). With the above code removed from myext.php everything's fine (with $wgExtensionCredits in myext.php, I can see myext in the Special:Version).
Is it the right thing to do (then what is the mistake) or is there a better/simpler way to start with?
500 means you have a syntax error or wrong configuration somewhere. Have you followed the instructions at Manual:How to debug and turned on PHP logging, so you can at least see what is causing the error? Alternatively, take a look at your Apache server log.
Also, you'll want to turn on debugging before you load your own extension!
Add these to LocalSettings.php for debugging:
error_reporting( -1 );
ini_set( 'display_startup_errors', 1 );
ini_set( 'display_errors', 1 );
$wgShowExceptionDetails=true;
$wgDebugToolbar=true;
$wgShowDebug=true;
$wgDevelopmentWarnings=true;
$wgDebugDumpSql = true;
$wgDebugLogFile = '/tmp/debug.log';
$wgDebugComments = true;
$wgEnableParserCache = false;
$wgCachePages = false;
You can log debug messages with wfDebug();

I created a duplicate of a download extension from my colleague which is basically an extension which just provides files to download in the back end.
Problem:
If i try to download a file while the extension is only accessible after login to the back end, then it works perfectly fine
however if I open a private browser window where I am not logged in to the back end, then it always cuts off the file and only download the first 40 KB ... even though it is normally 10 MB. Why is the file cut off?
I can download small files ( < 40KB ) perfectly without them getting cutted off.
NOTE:
Before I edited the extension, the download worked perfectly, even if not logged in to the back end! And the download was triggered the same way
Currently I am comparing the code, but from the logic it looks ok, since I did not changed much (added a new model, renamed the extension and some other stuff)
Does someone have a clue what can lead to this problem?
This is the relevant part in my download controller where I first get the public url of the file by passing the fid of the file and then trigger the download by sending headers.
...
if ($this->request->hasArgument('fid')) {
$this->fid = $this->request->getArgument('fid');
}
if ($this->request->hasArgument('cid')) {
$this->cid = $this->request->getArgument('cid');
}
$fileobj = $this->fileRepository->findByUid($this->fid);
if ($fileobj->getFile() !== null) {
$downloadFilePath = $fileobj->getFile()->getOriginalResource()->getPublicUrl();
if (file_exists($downloadFilePath)) {
$fileCounter = (int)$fileobj->getCounter();
$fileobj->setCounter(++$fileCounter);
$oldChecksum = $fileobj->getChecksume();
$groesse = filesize($downloadFilePath);
if (isset($oldChecksum)) {
$checksum = sha1_file($downloadFilePath);
$fileobj->setChecksume($checksum);
}
// update fileobj
$this->fileRepository->update($fileobj);
// Unset fileobj before persists, otherwise there will be also changes
$this->persistenceManager->persistAll();
// If file exists, force download
$fileName = basename($downloadFilePath);
$this->response->setHeader('Content-Type', "application/force-download", TRUE);
$this->response->setHeader('Content-Disposition', 'attachment; filename=' . $fileName, TRUE);
$this->response->setHeader('Content-Length', $groesse, TRUE);
#readfile($downloadFilePath);
$this->response->sendHeaders();
return true; //i can also delete this line, since it is never reached.
} else {
//send emails to everyone who is entered in the address list in the extension configuration.
$this->sendEmails('missing_file', $fileobj);
$this->redirect(
'list',
'Category',
NULL,
array(
'missing' => array(
'fileId' => $this->fid,
'category' => $this->cid
)
)
);
}
}
The 40 KB file does not contain anything that shouldn't be there, it is just cut off. I tested it by writing alot of numbers in a file line by line and download it, result: only a couple thousand numbers are in the file instead of all numbers.
I tried it with both, files stored at a FTP Server and files stored in user_upload, same result.
Here you can see the 40 KB file:
http://pasteall.org/459911
Snippet (in case if the link is down):
<ul>
<li>0</li>
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
<li>6</li>
<li>7</li>
<li>8</li>
<li>9</li>
//Cut because stackoverflow does not allow me to post such big texts
...
<li>3183</li>
<li>3184</li>
<li>3185</li>
<li>3186</li>
<li
You can see that it stops downloading the rest, the question is: why?
UPDATE:
I changed it to this:
// If file exists, force download
$fileName = basename($downloadFilePath);
$this->response->setHeader('Content-Type', "application/force-download", TRUE);
$this->response->setHeader('Content-Disposition', 'attachment; filename=' . $fileName, TRUE);
$this->response->setHeader('Content-Length', $groesse, TRUE);
ob_start();
ob_flush();
flush();
$content = file_get_contents($downloadFilePath);
$this->response->setContent($content);
$this->response->sendHeaders();
return true; //i can also delete this line, since it is never reached.
Now the file is downloaded completly, but the file is now wrapped inside the html from the template. it gets rendered inside the fluid variable mainContent.
Like this:
...
<!--TYPO3SEARCH_begin-->
<div class="clearfix col-sm-{f:if(condition:'{data.backend_layout} == 4',then:'12',else:'9')} col-md-{f:if(condition:'{data.backend_layout} == 4',then:'9',else:'6')} col-lg-{f:if(condition:'{data.backend_layout} == 4',then:'10',else:'8')} mainContent">
<f:format.raw>{mainContent}</f:format.raw>
</div>
<!--TYPO3SEARCH_end-->
...
It gets weirder and weirder...
I finally solved the problem. I just had to execute exit or die after sending the headers:
#readfile($downloadFilePath);
$this->response->sendHeaders();
exit;
NOTE: If you exit your code with exit or die then typo3 session set with e.g. $GLOBALS['TSFE']->fe_user->setKey("ses", "token", DownloadUtility::getToken(32)); won't work anymore if not logged in to the backend! Use $GLOBALS['TSFE']->fe_user->setAndSaveSessionData("token", DownloadUtility::getToken(32)); in this case if no log in should be required.
Now it works even if not logged in to the front end.
But I still don't know why the download worked without being cut off while being logged in to the backend, even though the exit statement was missing. Thats extremly weird and we have no explanation.
I'm trying to disable all visitor cookies for my Joomla website.
I found some tutorials, but they are for Joomla version:1.x
Any suggestions?
The solution is very similar to solution to remove cookies in Joomla version 1.x and 2.x. So we will use the same condition and principle.
If you change this two files then maybe something other will not work. Change this only if you know what are you doing and if you know that will everyting else work. Because you can break the whole website!
You must edit two files /libraries/src/Application/CMSApplication.php and libraries/joomla/session/handler/native.php
In libraries/src/Application/CMSApplication.php change code around line 166 and add if condition for whole code in method if (substr($_SERVER['SCRIPT_NAME'] , 0 , 14) == "/administrator"){
public function checkSession()
{
if (substr($_SERVER['SCRIPT_NAME'] , 0 , 14) == "/administrator"){ // added condition
$db = \JFactory::getDbo();
$session = \JFactory::getSession();
$user = \JFactory::getUser();
// ... rest of code
}
}
In libraries/joomla/session/handler/native.php change code around line 229 add if condition for whole code in method like in previous file
private function doSessionStart()
{
if (substr($_SERVER['SCRIPT_NAME'] , 0 , 14) == "/administrator"){ // added condition
// Register our function as shutdown method, so we can manipulate it
register_shutdown_function(array($this, 'save'));
// ... rest of code
}
}
This works in Joomla 3.8.2
Note: after every Joomla update you must edit this two files again and test if this solution still works.
Set the cookie-path "/administrator" in the Admin Joomla Settings (System => Configuration).
Then the session cookies are created only for the admin area.
To avoid all cookies for normal visitors, you need to follow the below steps.
First of all: Deactivate site statistics! Global configuration -> Statistics -> Statistics: No. This will stop the "mosvisitor" cookie.
Don't use the Template Chooser module, because it uses a cookie named "jos_user_template".
Be careful with components: Some might start their own PHP session.
Now to the main point: comment out line 697 of /includes/joomla.php like this:
// setcookie( $sessionCookieName, '-', false, '/' );
Additional: Comment out line 25 in /offline.php:
// session_start();
This seams to be an artifact of old versions.
Are there any roles to manage or create multiple wikis? I have checked Manual:Wiki family and understand the normal way of creating multiple wiki in a MediaWiki.
I'd like to share what I got in addition to the manual.
Beside of multiple domains/subdomain you can get also multiple path for multiple wikis. Each will stand with different configuration setup by adding the action path at the end line on each of your setting files as shown:
# End of automatically generated settings.
# Add more configuration options below.
$wgArticlePath = "/map/$1";
$actions = array( 'edit', 'watch', 'unwatch', 'delete','revert', 'rollback',
'protect', 'unprotect', 'markpatrolled', 'render', 'submit', 'history',
'purge', 'info' );
foreach ( $actions as $action ) {
$wgActionPaths[$action] = "$wgArticlePath/$action";
}
$wgActionPaths['view'] = "$wgArticlePath";
Change the map variable to your path on each of the setting files then place them under the folders named exactly follow to your path.
So you can modify the code in the LocalSettings.php similar as below:
<?php
// Include common settings to all wikis before this line (eg. database configuration)
$paths = explode('/' , $_SERVER['REQUEST_URI']);
if($paths[2] === NULL) {$path = 'map';} else {$path = $paths[1];}
switch ( $_SERVER['SERVER_NAME'] ) {
case 'wiki.tophyips.info':
require_once "settings/$path/tophyips.php";
break;
case 'wiki.hyipscript.info':
require_once "settings/$path/hyipscript.php";
break;
case 'wiki.hyipmonitors.info':
require_once "settings/$path/hyipmonitors.php";
break;
default:
header( 'HTTP/1.1 404 Not Found' );
echo 'This wiki is not available. Check configuration.';
exit( 0 );
}
Change the map variable on $path = 'map'; to one of your default path of your choice from all the paths you put on the setting files above.
You may check the result of the configuration above on my wiki family page.
The mediawiki::wiki module is used for creating wikis. Some roles that use it are commons and private (there are surely more). If you just want to create a wiki without any extra configuration, you can just write mediawiki::wiki{<wikiname>:} and put it in puppet/modules/role/manifests/my_role.pp (inside a role block - see other role files for the format) and then you can enable/disable via vagrant roles.
I ask this question, since I am trying to get the images I have just copied from Domain A to work in Domain B, (which is using the same database).
http://DOMAIN_A/magento/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/b/0/b0041-1.jpg
I think knowing what the 32 character string is, which help me find a good explanation why the images are not being found in the front or backend of Magento after reinstall on DOMAIN B.
RE: Magento version 1.4.0.1
Here's the code that creates that filename path, found in Mage_Catalog_Model_Product_Image:
// build new filename (most important params)
$path = array(
Mage::getSingleton('catalog/product_media_config')->getBaseMediaPath(),
'cache',
Mage::app()->getStore()->getId(),
$path[] = $this->getDestinationSubdir()
);
if((!empty($this->_width)) || (!empty($this->_height)))
$path[] = "{$this->_width}x{$this->_height}";
// add misk params as a hash
$miscParams = array(
($this->_keepAspectRatio ? '' : 'non') . 'proportional',
($this->_keepFrame ? '' : 'no') . 'frame',
($this->_keepTransparency ? '' : 'no') . 'transparency',
($this->_constrainOnly ? 'do' : 'not') . 'constrainonly',
$this->_rgbToString($this->_backgroundColor),
'angle' . $this->_angle,
'quality' . $this->_quality
);
// if has watermark add watermark params to hash
if ($this->getWatermarkFile()) {
$miscParams[] = $this->getWatermarkFile();
$miscParams[] = $this->getWatermarkImageOpacity();
$miscParams[] = $this->getWatermarkPosition();
$miscParams[] = $this->getWatermarkWidth();
$miscParams[] = $this->getWatermarkHeigth();
}
$path[] = md5(implode('_', $miscParams));
// append prepared filename
$this->_newFile = implode('/', $path) . $file; // the $file contains heading slash
So, the hash is generated from the configuration info (aspect ratio, etc), as well as the watermark info. This information will not usually change. However, I do see that the path is partially generated from the store_id of the current store, so your trouble may be there.
Is there a reason you can't let Magento use its normal caching procedures for both stores? Since Magento checks the filesystem for the cached image, there shouldn't be a conflict.
Hope that helps!
Thanks,
Joe
Upon contemplation, are you just trying to get the catalog images to work in both domains? The non-cached version of the catalog images are at %magento%/media/catalog/product. Copy the directories from that location and your catalog images should work.
Moving over the cached images isn't going to go far, since they will be deleted next time you flush the Magento cache. So, having moved the images that are in /media/catalog/product, flush the Magento image cache. Make sure that the file permissions are correct for reading. Then, head into Mage_Catalog_Model_Product_Image and take a look at the following code (approx line 270):
if ($file) {
// add these for debugging
Mage::log($baseDir.$file);
Mage::log(file_exists($baseDir.$file));
Mage::log($this->checkMemory($baseDir.$file));
if ((!file_exists($baseDir . $file)) || !$this->_checkMemory($baseDir . $file)) {
$file = null;
}
}
Add a var_dump or Mage::log statement in there (depending on whether you have logging enabled), and verify that the path to the images is correct, and that you have enough memory for the operation. This is the code that will choose the default image for you if no image path exists. If you still can't get it, post the output of those three logging statements and we'll keep trying. :)
I am trying to put second language on my webpage. I decided to use different files for different languages told apart by path - language/pl/projects.ln contains Polish text, language/en/projects.ln - English. Those extensions are just to tell language files from other, the content is simple php:
$lang["desc"]["fabrics"]["title"] = "MATERIAŁY";
$lang["desc"]["fabrics"]["short_text"] = "Jakiś tam tekst na temat materiałów";
$lang["desc"]["services"]["title"] = "USŁUGI";
$lang["desc"]["services"]["short_text"] = "Jakiś tam tekst na temat usłóg";
And then on the index page I use it like so:
session_start();
if (isset($_SESSION["lang"])) {
$language = $_SESSION["lang"];
} else {
$language = "pl";
}
include_once("language/$language/projects.ln");
print $lang["desc"]["fabrics"]["title"];
The problem is that if the session variable is not set everything works fine and array item content is displayed but once I change and set $_SESSION["lang"] nothing is displayed. I tested if the include itself works as it should by putting print "sth"; at the beginning of projects.ln file and that works all right both with $_SESSION["lang"] set and unset.
Please help.
Can you test the return value of session_start() - if it's false, it failed to start the session.
Is it being called before you output anything to the browser? If headers were already sent and your error_reporting level is too low, you won't even see the error message.
Stupid, but - do you set value of $_SESSION['lang'] to valid value like "en"? Does the English translation load correctly when you use it as default value in else block instead of "pl"?
"Jakiś tam tekst na temat usłóg" -> "usług" :)
Can you tell us what does this one output:
if(session_start()) {
echo SID, '<br/>';
if(isset($_SESSION['lang'])) {
echo 'lang = "',$_SESSION['lang'], '"';
}
}
Session starts fine and accidentally I managed to fix it.
I renamed $_SESSION['lang'] to $_SESSION['curr_lang'] and it now works allright. It seams like it didn't like the array and session variable having the same name (?).
