@ -9,14 +9,20 @@ But this conversion is not yet complete. This is a todo to keep track of the
status.
* The Abstract FilePath proposal (AFPP) has been implemented, and so a number of
libraries like unix and directory now have versions that operate on
libraries like directory now have versions that operate on
OSPath. That could be used in git-annex eg for things like
getDirectoryContents, when built against those versions.
(But OSPath uses ShortByteString, while RawFilePath is ByteString, so
conversion still entails a copy.)
* unix has modules that operate on RawFilePath but no OSPath versions yet.
See https://github.com/haskell/unix/issues/240
(OSPath uses ShortByteString, while RawFilePath is ByteString, so
conversion can entail a copy.)
* filepath-1.4.100 implements support for OSPath. It is bundled with
ghc-9.6.1 and above. Will need to switch from filepath-bytestring to
this, and to avoid a lot of ifdefs, probably only after git-annex no
longers supports building with older ghc versions.
* withFile remains to be converted, and is used in several important code
paths, including Annex.Journal and Annex.Link.
There is a RawFilePath version in file-io library, but that is
There is a OSPath version in file-io library, but that is
not currently a git-annex dependency. (withFile is in base, and base is
unlikely to convert to AFPP soon)
