The t_rename_secure / t_symlink_secure / t_acl unit harnesses (C), the rsyncfns.py helper library (daemon fixtures, symlink matrix, tree compare, xattr/ACL drivers), runtests.py, and the rsync_proto/xrsync/cmptree/mkvariety helper scripts that the security tests build on.

"""Compare two directory trees and print any differences.
|
|
|
|
Reuses rsyncfns.compare_trees(), so it is special-file aware (never
|
|
opens a fifo/socket/device as a stream) and reports differences in: the tls
|
|
listing (type, mode, owner, size, mtime, symlink target for every inode),
|
|
regular-file contents, user xattrs, POSIX ACLs, and hard-link grouping.
|
|
|
|
Works on any two trees, not just ones built by mkvariety.py. Exit status is 0
|
|
when the trees match, 1 when they differ.
|
|
|
|
Examples:
|
|
testsuite/cmptree.py /tmp/vt/transfer_root /tmp/copy
|
|
testsuite/cmptree.py --no-acls --no-xattrs treeA treeB
