#37505 [NEW]: touch() truncates large files
From: radu dot rendec at ines dot ro
Operating system: GNU/Linux i386
PHP version: 5.1.5CVS
PHP Bug Type: Streams related
Bug description: touch() truncates large files
Description:
------------
The touch() function truncates the file if it is a "large file" (i.e.
larger than 2GB).
Current PHP touch() implementation uses stat() to test if the file already
exists and only checks the return value, assuming that -1 means the file
does not exist. However, with large files, stat() fails with "Value too
large for defined data type".
Reproduce code:
---------------
<?php
touch("test");
?>
Expected result:
----------------
File "test" remains intact, only file times change.
Actual result:
--------------
File "test" is truncated to 0 (all contents is lost). This only happens
when "test" was larger than 2GB.
