[Bug 264313] Re: ls --color hangs for directories linked from network

[Amos]

I do think the fact that a workaround exists is not enough. I really
think the default behaviour in Ubuntu of a oft-used command should not
create hangs of well over a minute in fairly standard circumstances. It
also hangs on links that are not accessible because they have not been
Kerberos authenticated or are on unmounted USB devices.

So I do think the default should at least be changed here. It is
unreasonable default behaviour, not least because it is really unobvious
to most users why it happens.

Title:
  ls --color hangs for directories linked from network

Status in coreutils package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: coreutils

  ls --color hangs for directories linked from network resources if those resources are not available
  I guess it hangs in trying to validate the link ( have not tried to wait and see if it times out or not )

  easily reproducible.

  annoying since --color is default

  Running Ubuntu 8.0.4
  2.6.24-21-generic #1 SMP Mon Aug 25 16:57:51 UTC 2008 x86_64 GNU/Linux
  ls (GNU coreutils) 6.10

  ISSUE:

  since ls --color will try to determine if a symlink is broken or not
  (so that it will be correctly coloured), it *will* timeout on vanished
  resources.

  WORKAROUND:

  Inhibit 'ls' from following symlinks (at least in the context of --color):
  eval `dircolors -b | sed s/or=[^:]*://`

  Add the above to your profile.
