Previously, when cleaning up the temporary directory tree created by
passing G_TEST_OPTION_ISOLATE_DIRS, any symbolic links in that tree
would be followed recursively. If the test case has created a symbolic
link in its temporary directory to a directory outside that tree, this
could lead to unexpected data loss; in particular, if the test case
author has (unwisely) created a symbolic link to /, they could lose all
data on the system.
On systems that have the ftw.h header, replace the current rm_rf()
implementation with one that uses nftw() to perform a depth-first
traversal (FTW_DEPTH) without following symbolic links (FTW_PHYS), and
without crossing mount points (FTW_MOUNT) in case a test has mounted
some other filesystem in the temporary directory.
The callback logs any error to the standard error stream, but returns 0
rather than -1 to allow nftw() to keep walking the tree rather than
terminating immediately. Suppose we are trying to clean up the following
tree:
tmpdir/
a/
f/ (directory not readable for some reason)
g/
p
b/
c
d
Since tmpdir/a/f is not readable, we can expect to fail to delete
tmpdir/a/f, tmpdir/a and tmpdir; but it is preferable to (attempt) to
delete the rest of the tree rather than failing outright. The cost is
that three errors will be logged (for tmpdir/a/f, tmpdir/a and tmpdir).
nftw() is part of POSIX.1-2001, SUSv1, and glibc ≥ 2.1, so should be
available on effectively every platform except Windows. (And Windows
does not enable symbolic links by default so the developer error is less
likely to occur there.)
The macOS ftw(3) manpage says:
> These functions are provided for compatibility with legacy code. New
> code should use the fts(3) functions.
fts(3) does not seem to be part of any standard, but it does seem to be
equally widely supported. The Linux manpages do not indicate that
nftw() is deprecated.
