tests: Add virfilewrapper -- the new super "mock" This mock (which is actually not mock at all, see later) can redirect all accesses to a path into another path. There is no need to create mocks for particular directories, you just create a directory with all the data a redirect the test there. In the future, this should also be able to register callbacks for calls/paths, e.g. when the test is going to write into anything under "/sys/devices", call function fce(); Then in the open() call we would add information about the fd into some structure and in write() we would call fce() with parameters like @path to write to, @data to be written and pointer to optional return value, so that fce() itself could stop the call from happening or change its behaviour. But that's an idea for a latter day. This is not a mock because it will not be preloaded, but compiled in the test itself. See future patches for usage.

#ifndef __VIR_FILE_MOCK_H__
Fix many mistakes & inconsistencies in header file layout This introduces a syntax-check script that validates header files use a common layout: /* ...copyright header... */ <one blank line> #ifndef SYMBOL # define SYMBOL ....content.... #endif /* SYMBOL */ For any file ending priv.h, before the #ifndef, we will require a guard to prevent bogus imports: #ifndef SYMBOL_ALLOW # error .... #endif /* SYMBOL_ALLOW */ <one blank line> The many mistakes this script identifies are then fixed.
