RE: [Valgrind-users] BerkeleyDB gets bogus errno in Valgrind

[Troels W. H. <tr...@th...>]

Sorry, I managed to forget to attach the script.

Here's the script, as well as two straces, created with the below
commands, on a RH8+glibc 2.3.3 machine.

strace python dbboguserrno.py 2> strace-normal.txt
strace valgrind python dbboguserrno.py 2> strace-valgrind.txt

Both traces show the below syscall, but the instance running in Valgrind
seems to get EAGAIN instead...

open("nosuchfile.db", O_RDONLY|O_NONBLOCK|O_LARGEFILE) = -1 ENOENT (No
such file or directory)
