During DistriBits 2024, we discussed a concept that you seemed to like: emulating versioned tree export on a special remote with a non-versioned filesystem. This could be a generic mechanism of git-annex. Maybe a new option for the special remote (say: 'versioning = yes / no / emulated' or 'exporttree = yes / no / emulated')?
|
||||
|
||||
The idea is to save target files in the remote at paths reflecting the ones in the repo, but:
|
||||
- create an extra directory at the end of the path identical to the filename,
|
||||
- directory name includes the original extension of the file, which may seem a bit odd, but ensures no ambiguities,
|
||||
- inside the directory, save the file under filename = key (preferably add the original extension).

Advantages:
|
||||
- easy to implement,
|
||||
- you get (kind of) versioning on any POSIX-like filesystem,
|
||||
- older versions of files are never overwritten (history tracking),
|
||||
- it's sufficient to push only the changed files,
|
||||
- users can use the remote filesystem directly, as it represents something meaningful.

|

|

Disadvantages:
|
||||
- not perfect,
|
||||
- users need to accept the inconvenience caused by file naming on the bottom level,
|
||||
- it may be hard to find the right file version in the remote, especially if there are lots of them;

|
||||
- modification times will certainly help here,
|
||||
- can we concatenate some extra information to the file names that could help in identification?
