* reorder repo parameters lastGravatar Joey Hess2011-11-08
| | | | | | | | | | | | | Many functions took the repo as their first parameter. Changing it consistently to be the last parameter allows doing some useful things with currying, that reduce boilerplate. In particular, g <- gitRepo is almost never needed now, instead use inRepo to run an IO action in the repo, and fromRepo to get a value from the repo. This also provides more opportunities to use monadic and applicative combinators.
* convert all git read/write functions to use ByteStringsGravatar Joey Hess2011-09-29
| | | | | | | | | | This yields a second or so speedup in unused, find, etc. Seems that even when the ByteString is immediately split and then converted to Strings, it's faster. I may try to push ByteStrings out into more of git-annex gradually, although I suspect most of the time-critical parts are already covered now, and many of the rest rely on libraries that only support Strings.

* Sped up unused.Gravatar Joey Hess2011-09-29
| | | | | | | | | | | | | Added Git.ByteString which replaces Git IO methods with ones using lazy ByteStrings. This can be more efficient when large quantities of data are being read from git. In Git.LsTree, parse git ls-tree output more efficiently, thanks to ByteString. This benchmarks 25% faster, in a benchmark that includes (probably predominately) the run time for git ls-tree itself. In real world numbers, this makes git annex unused 2 seconds faster for each branch it needs to check, in my usual large repo.

This parser should be fast. I hope.
