This looks good to me. And just to make sure I'm understanding properly,
OPEN_REL only valid if it is within
or contained in a sub-directory tree of the ORIG_CWD.
One other question, do we get into any trouble with regards to the CWD during
restore?
Example in program:
chdir("./subdir");
system("some_other_program"); // Checkpoint occurs while some_other_program is
running
So the CWD of some_other_program during run is ./subdir. When we restore
(assuming same location),
does that mean that some_other_program thinks that its CWD is ./subdir or .? I
believe if it's not
in ./subdir, then we could run into some strange behavior if it thereafter
tries to open files with relative paths.
Thanks.
