A.M. Kuchling added the comment:
I don't understand the bug being reported. The code you quote should
probably be written as "if (result < 0 && errno == EBADF)", but the block's net
effect is to ignore an error by resetting result and errno.
It doesn't matter if we occasionally set result and errno to 0 when result is
already zero, but errno happens to be set to EBADF from some earlier operation.
The open('xxx', O_RDONLY) would raise an exception, not return a fd of -1, so I
don't see how that can be used to trigger a problem.
Therefore I'll close this issue, but am willing to re-open it if someone can
explain a way this code could actually cause problems.
