# Issue #66530: We would ICE if someone compiled with `-o /dev/null`,
|
|
# because we would try to generate auxiliary files in `/dev/` (which
|
|
# at least the OS X file system rejects).
|
|
#
|
|
# An attempt to `-Ztemps-dir` into a directory we cannot write into should
|
|
# indeed be an error; but not an ICE.
|
|
#
|
|
# However, some folks run tests as root, which can write `/dev/` and end
|
|
# up clobbering `/dev/null`. Instead we'll use an inaccessible path, which
|
|
# also used to ICE, but even root can't magically write there.
|
|
#
|
|
# Note that `-Ztemps-dir` uses `create_dir_all` so it is not sufficient to
|
|
# use a directory with non-existing parent like `/does-not-exist/output`.
|
|
|
|
all:
|
|
# Create an inaccessible directory
|
|
mkdir $(TMPDIR)/inaccessible
|
|
chmod 000 $(TMPDIR)/inaccessible
|
|
|
|
# Run rustc with `-Ztemps-dir` set to a directory
|
|
# *inside* the inaccessible one, so that it can't create it
|
|
$(RUSTC) program.rs -Ztemps-dir=$(TMPDIR)/inaccessible/tmp 2>&1 \
|
|
| $(CGREP) 'failed to find or create the directory specified by `--temps-dir`'
|
|
|
|
# Make the inaccessible directory accessible,
|
|
# so that compiletest can delete the temp dir
