Bug description: getimagesize() gives warning on files containing less than
12characters of dat
Description:
------------
Checking the mime-types of files using getimagesize() produces a warning
(Warning: getimagesize() [function.getimagesize]: Read error!) if the file
contains less than 12 characters. That is, a file of any extension
containing the sequence abcdefghijk gives a warning. Trying to read a file
containing the sequence abcdefghijkl gives no warning. This is done on
PHP5.2.1.
Also tested this on PHP5.1.6, and it seems less than 11 characters gives a
warning.
Is php trying to read more bytes than available?
Reproduce code:
---------------
<?
/* the directory asdf/ is a directory which apache is the owner of */
exec("touch asdf/asdf");
fwrite(fopen("asdf/asdf", "w"), "abcdefghijk");
$im = getimagesize("asdf/asdf");
?>
Expected result:
----------------
no output, no warning
Actual result:
--------------
Warning: getimagesize() [function.getimagesize]: Read error! in
