Re: [libvirt] [PATCHv2 1/2] virFindFileInPath: only find executable non-directory

Without this patch, at least tests/daemon-conf (which sticks $builddir/src in the PATH) tries to execute the directory $builddir/src/qemu rather than a real qemu binary. * src/util/util.h (virFileExists): Adjust prototype. (virFileIsExecutable): New prototype. * src/util/util.c (virFindFileInPath): Reject non-executables and directories. Avoid huge stack allocation. (virFileExists): Use lighter-weight syscall. (virFileIsExecutable): New function. * src/libvirt_private.syms (util.h): Export new function. --- New in v2: Require S_ISREG, not !S_ISDIR; avoid access(X_OK) and instead document that ACLs are disregarded src/libvirt_private.syms | 1 + src/util/util.c | 53 ++++++++++++++++++++++++++++++--------------- src/util/util.h | 7 +++-- 3 files changed, 40 insertions(+), 21 deletions(-)
