revise directory upper bound for cautious-file

[byorgey]

The cautious-file package was uploaded in 2013 and it looks like a Hackage trustee made a revision in 2015. The maintainer (greenrd) has not been seen in quite a while and the listed source repository does not exist anymore (it was on patch-tag).

I would like the directory upper bound for cautious-file to be revised to allow directory < 1.4. I have tested that it builds, and also reviewed the code to see whether there is any potential breakage:

augustine :: ~/src/cautious-file-1.0.2 » grep Directory **/*.{hs,hsc}
src/System/IO/Cautious.hs:import System.Directory (canonicalizePath, renameFile)
Test.hs:import System.Directory (removeFile)

• There were no changes to renameFile or removeFile between directory 1.2 and 1.3.
• There was a change to canonicalizePath: canonicalizePath is no longer canonical for directories (trailing slashes) haskell/directory#63 . This would only cause a problem if cautious-file had been somehow depending on the old behavior that sometimes kept trailing slashes and sometimes didn't. From the way the output of canonicalizePath is used, I can't see how that could possibly be the case. Note also that the current version of cautious-file was uploaded in Jan 2013, at which time directory-1.2.0.1 was current; according to canonicalizePath is no longer canonical for directories (trailing slashes) haskell/directory#63 (comment) that version had the same behavior vis-a-vis trailing slashes as directory-1.3.x, so if anything, the update to allow directory-1.3 would restore the original behavior of canonicalizePath that cautious-file was written against, rather than breaking it.

The only reverse dependencies of cautious-file are tbox (long abandoned) and diagrams-haddock (my package).

So I'd say the maintainer is still around. However, to accelerate things we can do the relaxation and inform the author.

I've performed the requested relaxation (and a few additional metadata tweaks while at it); see

http://hackage.haskell.org/package/cautious-file-1.0.2/revisions/

and informed the author via email.
