Subject: curl: Report only ready sockets
|
|
|
|
Git-commit: 9abaf9fc474c3dd53e8e119326abc774c977c331
|
|
|
|
Instead of reporting all sockets to cURL, only report the one that has
|
|
caused curl_multi_do_locked() to be called. This lets us get rid of the
|
|
QLIST_FOREACH_SAFE() list, which was actually wrong: SAFE foreaches are
|
|
only safe when the current element is removed in each iteration. If it
|
|
possible for the list to be concurrently modified, we cannot guarantee
|
|
that only the current element will be removed. Therefore, we must not
|
|
use QLIST_FOREACH_SAFE() here.
|
|
|
