Summary: filesize() fails for files with high inode number
-Status: Open
+Status: Feedback
Type: Bug
Package: Filesystem function related
Operating System: Linux
PHP Version: 5.5.1

New Comment:
Are you using a 32 or 64 it system?
Could you please run the following on command line to see whether the syscall
for stat succeeds or fails so we can narrow the search:
$ strace php -nr 'filesize("DSC_5196_fx-1553725666.JPG");'
The relevant output is towards the end something like
stat("DSC_5196_fx-1553725666.JPG", 0x7fff38d27f80) = -1 ENOENT (No such file or
directory)
write(1, "\nWarning: filesize(): stat faile"..., 96
or
stat("DSC_5196_fx-1553725666.JPG", {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
thanks.

Description:
------------
I have a file for which filesize() can't return value. "stat" result for this
file:
Original file:
File: 'DSC_5196_fx-1553725666.JPG'

filesize() works for this new file.
I can't find any other difference between these two files.
I checked that filesize() works for files with inode number less or equal to
4126207367and doesn't work for files with inode number equal or greater than
4358705632. I didn't find files with inode number in between but I'm still
looking.
To me it seems that filesize() has problem with inode number higher than 2^32.
Test script:
---------------
<html>
<body>
<pre>
<?
$f1 =
'/home/services/httpd/html.galeria.michal.waw.pl/gallery/var/albums/988_Rok-2013/Sobota/DSC_5196_fx-1553725666.JPG';
$f2 =
'/home/services/httpd/html.galeria.michal.waw.pl/gallery/var/albums/988_Rok-2013/Sobota/DSC_5196_fx-1553725666_X.JPG';
print $f1.": ".filesize($f1)."\n";
print $f2.": ".filesize($f2)."\n";
?>
</pre>
</body>
</html>
Expected result:
----------------
I expected to see sizes of both files.
Actual result:
--------------
Warning: filesize(): stat failed for
