Media Wiki 1.42 / using xampp v3.3.0 with Apache/2.4.58 (Win64) OpenSSL/3.1.3 PHP/8.2.12 - this could be corrected by know but I wanted it up here just in case.

After attempting an upload of a ".rdp" file not uploading as application/x-rdp type but continuously as : NxWare-SVN.rdp ‎(file size: 2 KB, MIME type: text/plain)

I could not get the file to do what I wanted with it coming in as a Text/Plain Changed apache/php/and localSettings multiple time to no avail with all instruction available to me online. Tested with a separate php file importer I created using Html and php: <?php if ($_FILES) { // Get the uploaded file $file = $_FILES['file']['tmp_name']; $fileName = $_FILES['file']['name'];

// Open the file info object to check its MIME type $fileInfo = finfo_open(FILEINFO_MIME_TYPE); $mimeType = finfo_file($fileInfo, $file); // Get the MIME type finfo_close($fileInfo); // Close the file info object

// If the MIME type is incorrectly detected, override based on the file extension if ($mimeType == 'text/plain' && pathinfo($fileName, PATHINFO_EXTENSION) == 'rdp') { $mimeType = 'application/x-rdp'; // Override to the correct MIME type for .rdp files }

echo 'Uploaded file: ' . $fileName . '<br>'; echo 'MIME Type: ' . $mimeType . '<br>'; echo 'File Size: ' . $_FILES['file']['size'] . ' bytes<br>'; }

and

<form action="MimeType.php" method="POST" enctype="multipart/form-data"> <label for="file">Upload an .rdp file:</label> <input type="file" name="file" id="file" accept=".rdp" required> <button type="submit">Upload</button> </form>

and the file would come up correctly, so I knew apache and php was correct it was just the php's in Media wiki So, after some messing around and pinpointing I narrowed it down to the MWFileProps.php that is called from UploadBase.php.

in the function: public function getPropsFromPath I modified and changed it to the following, just to handle rdp-files, if there is another file type you have an issue with you can modify it to match you mime information and it should load correctly: public function getPropsFromPath( $path, $ext = true ) { // SAFE PATCH: Detect .rdp extension reliably $checkExt = null;

if ( is_string( $ext ) && strtolower($ext) === 'rdp' ) { $checkExt = 'rdp'; } elseif ( is_string( $path ) && strtolower(pathinfo($path, PATHINFO_EXTENSION)) === 'rdp' ) { $checkExt = 'rdp'; }

if ( $checkExt === 'rdp' && is_string($path) && file_exists($path) ) { $fsFile = new FSFile( $path ); return [ 'fileExists' => true, 'size' => $fsFile->getSize(), 'sha1' => $fsFile->getSha1Base36(), 'mime' => 'application/x-rdp', 'file-mime' => 'application/x-rdp', 'major_mime' => 'application', 'minor_mime' => 'x-rdp', 'media_type' => 'UNKNOWN', // was MEDIATYPE_BINARY 'metadata' => [], 'width' => null, 'height' => null, 'bits' => null, 'pageCount' => null, 'duration' => null, 'commentCount' => null, ]; } $fsFile = new FSFile( $path );

$info = $this->newPlaceholderProps(); $info['fileExists'] = $fsFile->exists(); if ( $info['fileExists'] ) { $info['size'] = $fsFile->getSize(); // bytes $info['sha1'] = $fsFile->getSha1Base36();

# MIME type according to file contents $info['file-mime'] = $this->magic->guessMimeType( $path, false ); # Logical MIME type $ext = ( $ext === true ) ? FileBackend::extensionFromPath( $path ) : (string)$ext;

# XXX: MimeAnalyzer::improveTypeFromExtension() may return null (T253483). # Unclear if callers of this method expect that. $info['mime'] = $this->magic->improveTypeFromExtension( $info['file-mime'], $ext );

[ $info['major_mime'], $info['minor_mime'] ] = File::splitMime( $info['mime'] ); $info['media_type'] = $this->magic->getMediaType( $path, $info['mime'] );

# Height, width and metadata // @phan-suppress-next-line PhanTypeMismatchArgumentNullable See XXX above $handler = MediaHandler::getHandler( $info['mime'] ); if ( $handler ) { $sizeAndMetadata = $handler->getSizeAndMetadataWithFallback( $fsFile, $path ); if ( $sizeAndMetadata ) { $info = $sizeAndMetadata + $info; } } }

return $info; }

The creators can tell you if this is a bad idea, but it works for what I needed it for. Just thought I would share after 5 hours of troubleshooting this.
