Git Manipulation
The Git plugin provides Git-related combinators. It defines types for local Git repositories, Git commits inside these repositories and shell command to run on a given checkout.
val v : ?remote:string -> logs:Live_log.manager -> string -> tv ~remote ~logs dir is the local Git repository at dir. If dir does not exist, it is created by git clone remote. If remote is not given and dir does not exist, an exception is raised.
val hash : commit -> stringhash c is c's hash.
is_after ~old c is true iff old appears in the history of c.
fetch_head t target evaluates to a local branch in t with a copy of target's head commit (downloading it first if needed).
val with_checkout :
log:Live_log.t ->
job_id:job_id ->
commit ->
(string -> 'a Lwt.t) ->
'a Lwt.twith_checkout ~log ~job_id commit fn is fn path, where path is the path of a local checkout of commit. path must not be used after fn's thread terminates. The directory is locked while fn runs with job_id displayed to show why it is busy.
val with_clone :
log:Live_log.t ->
job_id:job_id ->
commit ->
(string -> 'a Lwt.t) ->
'a Lwt.twith_clone is similar to with_checkout but clones the repository to a temporary directory first. This means that the repository does not need to be locked while the callback function runs.
val command :
logs:Live_log.manager ->
timeout:float ->
label:string ->
clone:bool ->
string array list ->
commandcommand ~logs ~timeout ~label ~clone cmds is a caching executor of cmds, which caches results in a branch whose name includes label. The command will be terminated if it exceeds timeout seconds. If clone is set then with_clone is used rather than with_checkout. Note: every command must have a unique label!
