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 problimatic 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 processes's 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. |
