-Status: Open
+Status: Bogus
Bug Type: Filesystem function related
Operating System: FreeBSD4.3(ufs) / WinXPpro(ntfs)
PHP Version: 4.3.4
New Comment:
Your operating system(s) are reporting the old value because they
haven't yet committed the contents -->
try using fflush(). If you already have the file opened,
use fstat().
Note that (especially under windows), doing anything with a file that
is opened by some other process is not guaranteed to give you sane
results until some unknown time after the other process has released
its handle on the file.
Since there is nothing that PHP can do about this, it is
not a PHP bug, so setting status to bogus.

Are your reading my description well?
"When opened file grows during script run, filesize still report old
size. Cached filesize? But clearstatcache() before filesize() can't
help."
I already try clearstatcache()!

RTFM:
Note: The results of this function are cached. See clearstatcache() for
more details.

Description:
------------
When opened file grows during script run, filesize still report old
size. Cached filesize? But clearstatcache() before filesize() can't
help.
On FreeBSD 4.3-STABLE there is no this unexpected behaviour - it's all
ok without any clearstatcache();
I get my "bbbbbb" on WindowsXP/ntfs when when I use fread($fd_2, 1024)
instead of fread($fd_2, filesize('test')).
In production environment i'll get this behavior during concurrent file
read/write from two simultaneously running script. I think at leas this
behavior must be same at all platforms, so it's a bug.
Reproduce code:
---------------
<?
$fd=fopen('test', 'wb');
fwrite($fd, 'aa');
fclose($fd);
$fd_1=fopen('test', 'rb+');
$fd_2=fopen('test', 'rb+');
fwrite($fd_1, 'bbbbbb');
echo fread($fd_2, filesize('test'));
fclose($fd_1);
fclose($fd_2);
?>
Expected result:
----------------
bbbbbb
Actual result:
--------------
FreeBSD 4.3-STABLE (ufs):
bbbbbb
Windows XP pro (ntfs):
bb
