The git-annex Windows port is beta, but rapidly becoming polished and usable! ## status * There can be problems when the git-annex repository is in a deep or long path. Ie, `C:\loooooooooooooooooongdir\`. [Details here](http://git-annex.branchable.com/bugs/__34__git-annex:_direct:_1_failed__34___on_Windows) Workaround: Put your git-annex repo in `C:\annex` or some similar short path if possible. Workaround: Enable long paths in the registry. See * Local pairing seems to fail, after acking on Linux box, it stalls. (Also, of course, the Windows box is unlikely to have a ssh server, so only pairing with a !Windows box will work.) * gcrypt is not ported to windows (and as a shell script, may need to be rewritten) * Deleting a git repository from inside the webapp fails "RemoveDirectory permision denied ... file is being used by another process" * Tor remotes are not supported yet. Should not be very hard to get it working. ## potential encoding problems [[bugs/Unicode_file_names_ignored_on_Windows]] is fixed, but some potential problems remain, since the FileSystemEncoding that git-annex relies on seems unreliable/broken on Windows. * When git-annex displays a filename that it's acting on, there can be mojibake on Windows. For example, "háčky.txt" displays the accented characters as instead the pairs of bytes making up the utf-8. Tried doing various things to the stdout handle to avoid this, but only ended up with encoding crashes, or worse mojibake than this. * `md5FilePath` still uses the filesystem encoding, and so may produce the wrong value on Windows. This would impact keys that contain problem characters (probably coming from the filename extension), and might cause interoperability problems when git-annex generates the hash directories of a remote, for example a rsync remote. * `encodeW8` is used in Git.UnionMerge, and while I fixed the other calls to encodeW8, which all involved ByteStrings reading from git and so can just treat it as utf-8 on Windows (via `decodeBS`), in the union merge case, the ByteString has no defined encoding. It may have been written on Unix and contain keys with invalid unicode in them. On windows, the union merge code should probably check if it's valid utf-8, and if not, abort the merge. * If interoperating with a git-annex repository from a unix system, it's possible for a key to contain some invalid utf-8, which means its filename cannot even be represented on Windows, so who knows what will happen in that case -- probably it will fail in some way when adding the object file to the Windows repo. * If data from the git repo does not have a unicode encoding, it will be mangled in various places on Windows, which can lead to undefined behavior. ## minor problems * webapp lets user choose to encrypt repo, and generate gpg key, before checking that gcrypt is not installed * Ssh connection caching does not work on Windows, so `git annex get` has to connect twice to the remote system over ssh per file, which is much slower than on systems supporting connection caching. * glacier-cli is not easily available (probably) ## stuff needing testing * test that adding a repo on a removable drive works; that git is synced to it and files can be transferred to it and back * Does stopping in progress transfers work in the webapp? ## do we need this port anymore? See If windows has transparent support for running linux executables, and those executables can access files in "." which are on the windows system, then you could just use this to run linux git-annex on windows. No port needed. That would be great! Seems like this would need Windows 10. > The latest builds of Windows 10 (build 15063) can run git-annex in the > Windows Subsystem for Linux.
