Summary: Signals not catchable when certain functions are in
execution
Status: Open

Package: PCNTL related
Operating System: Linux

Actually it is due to syscall restarting by default. You should pass third
argument as "false" to pcntl_signal and you will be able to catch SIGINT, but
only after second attempt. The other bug I created (https://bugs.php.net/bug.php?
id=52121) addresses more severe case, I suppose

Ok.But I guess that this behavior is not that anyone expect.
Some one else can give the final word ?

PHP signals are implemented with ticks
(http://us3.php.net/manual/en/control-structures.declare.php). Ticks are events that occur every so
much statements in a script. Since fgets() blocks, no more statements are executed and no more ticks
are fired. This means that no signal arrives.
I do not know whether the current behavior is by design or by mistake, so I cannot determine whether
it is a bug or not. It would certainly be desirable to be able to interrupt a blocking read by doing
Ctrl-C.

Where I say:
'There is true?',
is
'That's true?'

The problem is that I need hit enter - exit from fgets - to run the signal handler - but this is not
the correct way - in python for example, the signal handler are calling when the function are
waiting for a user input.
I found this page - http://br2.php.net/manual/en/function.pcntl-signal.php
- the commentary above:
'28-Mar-2006 07:26
Process handling is not available when using a blocking socket! Bear this in mind.'
There is true?
