Well, sugar. (In the expletive sense...)
Looks like cmFileCommand.cxx has an implementation of
cmFileCommand::HandleRemove that implements both REMOVE and
REMOVE_RECURSE and it ........ (wait for it) .......... always returns
true. Always. Regardless of any failed attempts at removing files. We
completely ignore the return value of the underlying file system
remove calls.
It's probably failing for some permissions, ownership or locking
related reason, but file(REMOVE provides no error diagnostics. Do you
have permissions to remove the directory in question? Is there an
executable down in that directory that is open/running when this
attempt is made? (An open app on the Mac cannot be deleted until it is
not running anymore...)
Grrr. Good (but bad) bug find. Do you have time to add a bug at
http://public.kitware.com/Bug ?
Is this reproducible in general on your Mac, or is it specific to the
one directory?
If a general problem, then the following code should leave the
directory and produce a FATAL_ERROR:
file(MAKE_DIRECTORY test_dir)
file(WRITE "test_dir/file1" "file1 contents")
if(NOT EXISTS "test_dir/file1")
message(FATAL_ERROR "test_dir/file1 does not exist!! should be
created by now")
endif()
if(NOT EXISTS "test_dir")
message(FATAL_ERROR "test_dir does not exist!! should be created by now")
endif()
file(REMOVE_RECURSE "test_dir")
if(EXISTS "test_dir/file1")
message(FATAL_ERROR "test_dir/file1 still exists!! should be deleted now")
endif()
if(EXISTS "test_dir")
message(FATAL_ERROR "test_dir still exists!! should be deleted now")
endif()
And finally: does it still happen after a reboot?
Hopefully people won't complain about "backwards compatibility" issues
that arise when we fix it.
Thx,
David
