write access permission of binary result different on OpenBSD

[ivdsangen]

Checking the write access of the binary itself gives a different result on OpenBSD. Therefore excluding the test case on OpenBSD host.

For reference comare the results of this program on OpenBSD: #include<unistd.h> int main() {

printf("%i\n", access("test",W_OK) == 0);

}

Disable test case on OpenBSD host

call to getPermissions on binary itself results in getPermissions001: getPermissions001: fileAccess: resource busy (Text file busy)

Thanks for the report.

I think we should catch the exception and have OpenBSD-specific output.

The behavior is same on NetBSD. I suppose it is same on FreeBSD too (not checked).

To handle ETXTBSY (and EROFS) in unix package will fix it.

This fix seems proper on Linux according to the man page.

 http://man7.org/linux/man-pages/man2/access.2.html

access() shall fail if:

EROFS  Write permission was requested for a file on a read-only file
             system.

access() may fail if:

ETXTBSY
              Write access was requested to an executable which is being executed.

Handle EROFS and ETXTBSY for write permission check

Expected outputs of getPermissions001 for NetBSD
