Well, I've been digging around a bit. After reading the git-fast-import
man page and doing some experiments, I've discovered the following:
The "R " record has exactly the same syntax as the "C " record.
Therefore, for each file that has been renamed there is a commit record
like:
R old_name new_name
If, apart from a rename, there were changes in the file contents, an
additional "M " record is appended just below the rename.
I'm not really sure about the value and support of file rename in
Fossil for three reasons:
1. There is no "copy" command
2. The "mv/rename" command does not actually operate on the
filesystem, but after the user has performed the operation
3. This mail:
http://lists.fossil-scm.org:8080/pipermail/fossil-users/2008-July/000325.html
I'm willing to carry on and try to fix this missing import piece, but
only if it is worth the trouble.
Does "mv/rename" improve the delta algorithm and/or file tracking in any
way?
Regards.
