To make sure 'distcheck' can pass for the Octave 5 release, I have added a temporary hack to workaround this bug in pkg on the stable branch:


Once this bug is succesfully fixed, so that a package tar with read-only contents can be installed and uninstalled without error, this workaround can be removed from the BIST tests.

If a package tar or zip contains files or directories that are marked read-only when the package distribution is created, maybe only directories, then 'pkg uninstall foo' fails with an error

couldn't delete directory /path/to/.../mfile_basic_test-0.1.0: Permission denied

In particular, when running 'make distcheck', the test suite is run from a read-only copy of the Octave source. This leads to 4 out of 10 test failures in pkg.tst.

IMHO, if pkg install works, then pkg uninstall must be able to undo whatever pkg install did. That means if the contents of the package were made restrictive in some way, either

1. pkg install must change permissions as necessary when unpacking/creating/copying, or
2. pkg uninstall must be able to delete things regardless of file permissions.

Also a test for this specific error should be added to pkg.tst. For example, create a copy of one of the minimal package directories in test/pkg, recursively chmod files and directories, and do an install/uninstall test.
