[PATCH] Force "hg clone" to always create a new directory -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [PATCH] Force "hg clone" to always create a new directory From: Bryan O'Sullivan <bos@serpentine.com> I just screwed myself by typing "hg clone foo" without specifying a destination directory, and after I was done mopping up the mess, concluded that this is a dangerous mode of operation that has no practical value. I've thus modified the clone command so that it always creates a destination directory. If none is specified, the destination is taken as the basename of the source. hg clone foo -> error, because foo already exists hg clone http://www.selenic.com/hg -> new repo, named hg hg clone ../bar -> new repo, named bar manifest hash: f21ed8f805a60c1326d99220772e1574b0870d6c -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCwxsIywK+sNU5EO8RAgooAKC3IL6vKyADb9s2qqqi4GMw2Z7asACbBtE/ TvPgwGtIiB2GC+N+V7r1VpI= =uTcK -----END PGP SIGNATURE-----
