11. OSErrors

As a convenience, Shrapnel wraps all OSError exceptions that it raises with a subclass that is specific to the errno code. For example, an OSError with an errno of ENOENT will be raised as the ENOENT exception. All exceptions derive from OSError, so it is compatible with regular OSError handling.

All of the exceptions are defined in the coro.oserrors module.

For example, instead of doing this:

try:
    data = sock.recv(1024)
except OSError, e:
    if e.errno == errno.ECONNRESET:
        # Handle connection reset.
    else:
        # Handle other unknown error.

You can do this:

try:
    data = sock.recv(1024):
except ECONNRESET:
    # Handle connection reset.
