Bug description: Apache don't return right connection status
Description:
------------
hello i'm writing an script to draw a graph
an explanation about script:
my graph is 1024x800 pixels and about 50000 points i'm using spline to get
1024 points (to draw less points and use less GD library, but using more
cpu to run spline function)
the main problem is when my client (browser) stop work
since i'm running with set_time_limit(0) and ignore_user_abort(1) (i'm
using temporary files to read points) i can't get right value from
connection_aborted
i was reading manual and some users tell that connection_aborted only
works when i "echo" some caracters, since i'm drawing images i can't
change document content, if i change my image will be damaged and won't
display on browser
can i get right connection_aborted status?!
thankx
Reproduce code:
---------------
<?php
set_time_limit(0);
ignore_user_abort(1);
while(1){
if (connection_aborted()) break;
// i put connection aborted in many parts of my script, but this
example could be something like i do
}
?>
Expected result:
----------------
using htop i see that apache process cpu usage still high after stop from
my firefox browser
apache should know that i stoped, maybe browser didn't send connection
stop? or maybe apache didn't send connection stop to php? i'm using php as
module an not as cgi!
expected result should be an process cpu usage with low values after stop
from firefox
Actual result:
--------------
high cpu values (98%) on apache process
after stop (another process) run at (0.2% or less)
