|
|||
* balanced= and fullybalanced= need to limit the set of repositories to
|
||||
ones with enough free space to contain a key.
|
||||
|
||||
* Implement [[track_free_space_in_repos_via_git-annex_branch]]
|
||||
* Implement [[track_free_space_in_repos_via_git-annex_branch]]:
|
||||
|
||||
* Load Annex.reposizes from Database.RepoSizes on startup.
|
||||
|
||||
* When Annex.reposizes does not list the size of a UUID, and
|
||||
that UUID's size is needed eg for balanced preferred
|
||||
content, read the git-annex branch to get all repo sizes,
|
||||
the same way `git-annex info` gets repo sizes. And store in
|
||||
Database.RepoSizes.
|
||||
|
||||
* Update Annex.reposizes after each successful transfer.
|
||||
|
||||
* Update Database.RepoSizes during merge of git-annex branch.
|
||||
(Also update Annex.reposizes)
|
||||
|
||||
* On commit of git-annex branch, update Database.RepoSize to reflect
|
||||
the size changes in the commit.
|
||||
|
||||
Probably cannot use Annex.reposizes for the values, since they must
|
||||
match the sizes in the location log files being committed. Note
|
||||
that other processes may journal location log changes, which will be
|
||||
part of the commit. So need to read all the changed location logs,
|
||||
and update Database.RepoSize accordingly.
|
||||
|
||||
(Annex.reposizes can be updated to the resulting values.)
|
||||
|
||||
* Perhaps: setRepoSize to 0 when initializing a new repo or a
|
||||
new special remote (but not when reinitializing),
|
||||
and also update Annex.reposizes for that uuid.
|
||||
|
||||
Whether it makes sense to do this will depend on how expensive
|
||||
it is to update Database.RepoSize on git-annex branch merge and commit.
|
||||
If it is not expensive, will want to track reposizes from the beginning
|
||||
whenever possible, to avoid a later expensive read of the git-annex
|
||||
branch to calculate the reposizes.
|
||||
|
||||
* Make `git-annex info` use Annex.reposizes.
