After working on it all day, git-annex now builds on Windows!
Even better, git annex init
works. So does git annex status
, and
probably more. Not git annex add
yet, so I wasn't able to try much more.
I didn't have to add many stubs today, either. Many of the missing Windows features were only used in code paths that made git-annex faster, but I could fall back to a slower code path on Windows.
The things that are most problematic so far:
- POSIX file locking. This is used in git-annex in several places to make it safe when multiple git-annex processes are running. I put in really horrible dotfile type locking in the Windows code paths, but I don't trust it at all of course.
- There is, apparently, no way to set an environment variable in Windows from Haskell. It is only possible to set up a new process' environment before starting it. Luckily most of the really crucial environment variable stuff in git-annex is of this latter sort, but there were a few places I had to stub out code that tries to manipulate git-annex's own environment.
The windows
branch has a diff of 2089 lines. It add 88 ifdefs to the code
base. Only 12 functions are stubbed out on Windows. This could be so much
worse.
Next step: Get the test suite to build. Currently ifdefed out because it
uses some stuff like setEnv
and changeWorkingDirectory
that I don't know
how to do in Windows yet.
