Bug description:Problem with headers longer than 4008 under FPM
Description:
------------
There is a problem when headers sent from a script are longer than 4008
(see the test sript below). I'm currently using FPM with nginx 1.0.5.
If headers are longer than 4008, this happens:
for 4008, everything is OK,
for 4009, no output is displayed,
for 4010+, HTTP error 502 is returned.
Similar problem has been verified under PHP 5.3.5 with different
boundaries:
4012 is OK,
4013 is OK, but with no output,
4014 gives 502.
Test script:
---------------
OK:
header(str_repeat('x', 4008));
echo 'foo';
--------------------------------
OK, but no output:
header(str_repeat('x', 4009));
echo 'foo';
--------------------------------
HTTP error 502:
header(str_repeat('x', 4010)); //or anything higher
echo 'foo';
--------------------------------
OK:
header(str_repeat('x', 2000));
header(str_repeat('y', 2006));
echo 'foo';
--------------------------------
OK, no output:
header(str_repeat('x', 2000));
header(str_repeat('y', 2007));
echo 'foo';
--------------------------------
502:
header(str_repeat('x', 2000));
header(str_repeat('y', 2008));
echo 'foo';
Expected result:
----------------
foo
