a bug in zsh?

a bug in zsh?

[Markku.Jarvinen]

Hi!

From the docs this seems to be the right address to ask about a bug.

The system: Sun Sparc 
Operating system: Solaris 2.4 or Solaris 2.5

ZSH-version 2.6-beta19, 3.0pre2, 3.0pre3

BUG: when option chaselinks is set and I run zsh on a host
     which has automounted homedirectories command 'pwd'
     does weird things (i.e. changes directory to some random
     directory that was first mounted using automount).

I traced this to zgetcwd in compat.c, it tries to traverse
filesystem backwards looking for the path it came from, but
chdir("..") from a automounted directory is not same as chdir
into the parent of that directory, so this traversal fails.

Any suggestions other than turning chaselinks off?

That's because the automounter is implemented by mounting the directory
somewhere else and then setting up symlinks in the magic automount
directory to point to the actual mount location.  Zsh is doing the
right thing with respect to the symlinks.

Yeah; turn the automounter off.

There might be something that could be done by checking the results of
stat() on ".." and "." [which zgetcwd() is already doing] and change
the behavior when ".." crosses over to a different logical device.  I'm
not sure what, though.  You'd have to get the original path used by cd
back, and start working *down* until you found the directory at which
the device change took place.
