val name : t -> stringname t is t's name.
head t is the current head of the branch, or None if it doesn't currently exist.
val wait_for_head :
t ->
?switch:Lwt_switch.t ->
(Commit.t option -> [ `Finish of 'a | `Again | `Abort ] result) ->
[ `Abort | `Finish of 'a ] resultwait_for_head t fn calls fn commit on the current commit. If it returns `Again then it waits for the commit to change and tries again. If switch is provided, then turning off the switch will make the wait return `Abort at the next opportunity.
val wait_for_path :
t ->
?switch:Lwt_switch.t ->
Datakit_client.Path.t ->
([ `File of Cstruct.t
| `Dir of Tree.t
| `Link of string
| `Exec of Cstruct.t ]
option ->
[ `Finish of 'a | `Again | `Abort ] result) ->
[ `Abort | `Finish of 'a ] resultwait_for_path is similar to wait_for_head, but waits for a particular sub-tree to change.
fast_forward t commit changes t to point to commit if t's head is an ancestor of commit (or returns an error if not).
val with_transaction : t -> (Transaction.t -> 'a result) -> 'a resultwith_transaction t fn is the result of applying fn to a new transaction on branch t. If the transaction has not been committed when fn trans returns, the transaction is aborted (and a warning is logged). Use Transaction.abort to avoid the warning.
val transaction : t -> Transaction.t resulttransaction t creates a new transaction on top of the branch t. Must be closed with Transaction.abort or Transaction.commit. Use with_transaction to not have to worry about resource leaks..
