Re: [darcs patch] filepath: normalise trailing dot

Hi, I've re-opened ticket #3975 related to this proposal. It's a fairly minor patch which ensures that filepaths containing a trailing dot are normalised consistently, ie. the path "foo/bar/." is normalised to "foo/bar" Discussion period: 2 weeks cheers, Conrad.

Hi Conrad,

Your proposal seems sensible (+1). Although in the past some people complained about normalising away .'s being a bug in some corner cases, so if anyone can find one of them I withdraw my support.

Creating a trac ticket is important so that the patch doesn't get lost.

Hi,

apologies for the high latency, here is a trac ticket:

Thanks, Neil

Hi,

the attached darcs patch modifies the behaviour of normalise to handle trailing dots in a path. The previous behaviour yielded this:

Prelude System.FilePath> normalise "../." "../." Prelude System.FilePath> normalise ".././" ".././" Prelude System.FilePath> normalise ".././.." "../.."

This patch modifies dropDots such that the check for (".":[]) only occurs once for the path, after which a driver function dropDots' is used which skips this check. Hence "." can be removed from the end of a longer path, but a path of just "." is unchanged.

(my trac account is pending verification, I'll reply with a trac ticket # later if needed)

cheers,

Conrad.
