From: netclone at bigmir dot net
Operating system: Windows XP SP2
PHP version: 5.2.4
PHP Bug Type: Reproducible crash
Bug description: Resource descriptors leaks
Description:
------------
System halts, php hangs up - each file-resource handler becomes invalid.
I'm using CLI php.exe to process image storage with JPG files with
approximately size 2-3Mb each. Script uses database dump file each line of
them points to physical file location. This dump has 4000-6000 records.
Within cycle it reads one line from dump and call this code, and writes
result into log file. Its outputs ~180 files (~18Kb) per 3-5 sec. Crash
becomes at ~ 4h of work. Looks like no more handles aviable.
We have same results on 4 PCs (all PCs new, just bayed week ago, all
systems has same configuration Core2Duo/3GHz/2Gb, firmly HP), running on
Windows XP SP2 (all updates installed), installed extensions
php_oci8.dll, php_gd2.
Reproduce code:
---------------
$url = {image}; $FileDir = {path} //code to read IN file and open log
@mkdir($FileDir, 0755, true);
if( file_exists($FileDir) ) {
$InputImage = @ImageCreateFromJPEG( $url )
$iw = ImageSX($InputImage); $ih = ImageSY($InputImage);
$ThumbImage = @imagecreatetruecolor(124, 82))
imagecopyresampled($ThumbImage, $InputImage,0, 0, 0, 0, 124, 82, $iw,
$ih);
ImageJPEG($ThumbImage, $thumbnail, 80 );
ImageDestroy($ThumbImage);
$rows = ceil($iw /256); $cols = ceil($ih /256);
for($i = 0; $i < $rows; $i++ ) for( $j = 0; $j < $cols; $j++ ){
if ($OutputImage = @ImageCreateTrueColor( 256,256 ) {
ImageCopy( $OutputImage, $InputImage, 0, 0, $x, $y, $cw, $ch );
ImageJPEG( $OutputImage, $OutputFile, 80 );
ImageDestroy($OutputImage);
}
ImageDestroy($InputImage);
}
Expected result:
----------------
images in correpsonding folders
Actual result:
--------------
~4h all is ok, but at nearly 2500-2700 image it's write in log
PHP Warning: imagejpeg(): Unable to open 'xxx.jpg' for writing: Invalid
argument in script.php on line xx
PHP Warning: fwrite(): supplied argument is not a valid stream resource
PHP Warning: fclose(): supplied argument is not a valid stream resource
System hangs on, you can't open or run anything and need to reboot. During
this time created ~720 000 images
