@ -9,17 +9,12 @@ Benchmarking `git-annex find`, speedups range from 28-66%. The files fly by
much more snappily. Other commands likely also speed up, but do more work
than find so the improvement is not as large.
The `bs` branch is in a mergeable state now, but still needs work:
The `bs` branch is in a mergeable state now, except for:
* Profile various commands and look for hot spots.
* filepath-bytestring probably has issues with utf16 filenames
on Windows. See its TODO.
* ByteString.Char8.putStrLn may truncate?
Stuff not entirely finished:
* Eliminate all the fromRawFilePath, toRawFilePath, encodeBS,
decodeBS conversions. Or at least most of them. There are likely
some places where a value is converted back and forth several times.
* Use versions of IO actions like getFileStatus that take a RawFilePath,
avoiding a conversion. Note that these are only available on unix, not
windows, so a compatability shim will be needed.
(I can't seem to find any library that provides one.)
* Profile various commands and look for hot spots involving conversion
between RawFilePath and FilePath.
