[Yanel-dev] yarep patch to support splitting of paths

[Claudio Corrodi]

I added the feature that when trying to read a file that doesn't exist =

at the splitted destination but if it exists at the "original" =

destination, then the file is copied to the splitted path. Let me make =

an example:

In the filesystem, there is a file /data/foobar.txt and /data/ is the
repository root. Let's also assume that the repository is configured =

such that /foobar.txt results in reading/writing the file =

/data/foo/bar.txt. If /data/foo/bar.txt doesn't exist, but =

/data/foobar.txt does, then this update falls back to /data/foobar.txt =

after failing to get a stream for /data/foo/bar.txt. It then copies =

/data/foobar.txt to /data/foo/bar.txt and continues using the new =

(splitted) path.

Note that the old file isn't removed after copying, maybe we want to add
this functionality later.

Regards,
Claudio
