commit b185f2281d0e8767db4c1270280ec160b9fa097b
Author: Jan Stancek <jst...@re...>
Date: Thu Nov 14 10:05:51 2013 +0100
add test for tst_checkpoint_signal_child timing out
This is simple test for patch which adds timeout to
tst_checkpoint_signal_child().
The test is expected to end with:
Failed to open fifo 'tst_checkpoint_fifo' at
tst_checkpoint_no_child.c:43: errno=ETIMEDOUT(110): Connection timed out

commit cb80f404615db93b9486c88de186dcb729133727
Author: Stanislav Kholmanskikh <sta...@or...>
Date: Thu Nov 14 10:37:57 2013 +0400
tst_checkpoint_signal_child: implemented timeout
If a child exits before opening TST_CHECKPOINT_FIFO
for reading, tst_checkpoint_signal_child() issued from the parent
will block forever.
To handle such situations added timeout logic to tst_checkpoint_signal_child();
