// This test verifies that rustdoc doesn't ICE when it encounters an IO error
|
|
// while generating files. Ideally this would be a rustdoc-ui test, so we could
|
|
// verify the error message as well.
|
|
//
|
|
// It operates by creating a temporary directory and modifying its
|
|
// permissions so that it is not writable. We have to take special care to set
|
|
// the permissions back to normal so that it's able to be deleted later.
|

//@ ignore-riscv64
|

//@ ignore-arm
|
|
// FIXME: The riscv64gc-gnu and armhf-gnu build containers run as root,
|
|
// and can always write into `inaccessible/tmp`. Ideally, these docker
|
|
// containers would use a non-root user, but this leads to issues with
|
|
// `mkfs.ext4 -d`, as well as mounting a loop device for the rootfs.
|
|
//@ ignore-windows - the `set_readonly` functions doesn't work on folders.
