"""Represents a generated backend.mk file.
This is both a wrapper around a file handle as well as a container that
holds accumulated state.
It's worth taking a moment to explain the make dependencies. The
generated backend.mk as well as the Makefile.in (if it exists) are in the
GLOBAL_DEPS list. This means that if one of them changes, all targets
in that Makefile are invalidated. backend.mk also depends on all of its
input files.
It's worth considering the effect of file mtimes on build behavior.
Since we perform an "all or none" traversal of moz.build files (the whole
tree is scanned as opposed to individual files), if we were to blindly
write backend.mk files, the net effect of updating a single mozbuild file
in the tree is all backend.mk files have new mtimes. This would in turn
invalidate all make targets across the whole tree! This would effectively
undermine incremental builds as any mozbuild change would cause the entire
tree to rebuild!
The solution is to not update the mtimes of backend.mk files unless they
actually change. We use FileAvoidWrite to accomplish this.
