# When we intercept a fork/vfork with a catchpoint, the child is left
|
|
# stopped. At that point, if we kill the parent, we should kill the
|
|
# child as well. This test makes sure that works. See PR gdb/19494.
|
|
|
|
# The main idea of the test is make sure that when the program stops
|
|
# for a fork catchpoint, and the user kills the parent, gdb also kills
|
|
# the unfollowed fork child. Since the child hasn't been added as an
|
|
# inferior at that point, we need some other portable way to detect
|
|
# that the child is gone. The test uses a pipe for that. The program
|
|
# forks twice, so you have grandparent, child and grandchild. The
|
|
# grandchild inherits the write side of the pipe. The grandparent
|
|
# hangs reading from the pipe, since nothing ever writes to it. If,
|
|
# when GDB kills the child, it also kills the grandchild, then the
|
|
# grandparent's pipe read returns 0/EOF and the test passes.
|
|
# Otherwise, if GDB doesn't kill the grandchild, then the pipe read
|
|
# never returns and the test times out.
