Bug description: Using curl_multi_exec with curl_multi_fdset doesnt work
Description:
------------
I try to use curl_multi_fdset() together with curl_multi_exec() in php5.
But this doesn't work.
I modelled my php code after the sample (multi-app.c) which is provided by
the curl-src package.
Reproduce code:
---------------
this is the code I use for php5 (three single curl handles were added):
while (CURLM_CALL_MULTI_PERFORM == curl_multi_exec($m, $still_running))
;
while ($still_running) {
$fd = curl_multi_select($m, 1);
switch($fd) {
case -1:
break;
case 0:
default:
while (CURLM_CALL_MULTI_PERFORM == curl_multi_exec($m,
$still_running))
;
}
}
Expected result:
----------------
The code should behave like the multi-app.c sample. See
[curl-src]/docs/examples/multi-app.c.
Actual result:
--------------
The code runs in an endless loop. Because curl_multi_exec() (alias
curl_multi_perform()) needs to reference the variables readfds, writefds
which were set by a previous call to curl_multi_fdset(). But these fdsets
have gone out of scope. The C Code works because the fdsets are still
present on the stack. See man 3 curl_multi_fdset for further details. curl
--version gives:
