module Reference : Reference.S with type hash = hash
val dotgit : t -> Fpath.t
dotgit state
returns the current ".git"
path used - eg. the default ?dotgit
value of v
if the client does not notice a specific value.
val root : t -> Fpath.t
root state
returns the current path of the repository. eg. the default value ?root
value of v
if the client does not notice a specific value.
contents state
returns an associated list between the hash and its bind git object. This list contains all git objects available in the current git repository state
.
size state hash
returns the size of the git object which respects the predicate digest(object) = hash
. The size is how many byte(s) are needed to store the serialized (but not deflated) git object in bytes (without the header).
read state hash
can retrieve a git object from the current repository state
. It de-serializes the git object to an OCaml value.
val read_opt : t -> hash -> (Value.t option, decode_error) Stdlib.result Lwt.t
read_opt state hash
is like read
but does not return (or log) an error if the git object referenced by hash
cannot be retrieved from state
.
read_exn state hash
is an alias of read
but raise an exception (instead to return a result
) if the git object requested does not exist or when we catch any others errors.
mem state hash
checks if one object satisfies the predicate digest(object) = hash
.
list state
lists all git objects available in the current git repository state
.
write state v
writes the value v
in the git repository state
.
val batch_write :
t ->
hash ->
pck:(unit -> string option Lwt.t) ->
idx:(unit -> string option Lwt.t) ->
(unit, error) Stdlib.result Lwt.t
batch_write state map pack index
writes all objects indexed into index
and available into pack
in the git repository state
.
val fold :
t ->
('acc -> ?name:Fpath.t -> length:int64 -> hash -> Value.t -> 'acc Lwt.t) ->
path:Fpath.t ->
'acc ->
hash ->
'acc Lwt.t
fold state f ~path acc hash
iters on any git objects reachable by the git object hash
which located in path
(for example, if you iter on a commit, path
should be "."
- however, if you iter on a tree, path
should be the directory path represented by your tree). For each git object, we notice the path name
(derived from path
) if the object is a Blob or a Tree, the length
or the git object (see size
), the hash
and the value
.
If the hash
points to:
Value.Blob.t
: f
is called only one time with the OCaml value of the blob.Value.Tree.t
: f
is called firstly with the OCaml value of the pointed tree by the hash hash
. Then, we iter (and call f
for each iteration) in the list of entries of the tree. Finally, we retrieve recursively all sub-tree objects and do an ascending walk. f
is never called more than one time for each hash.Value.Commit.t
: f
is called firstly with the OCaml value of the pointed commit by the hash hash
. Then, it follows recursively all parents of the current commit, Finally, it starts a fold
inside the pointed root tree git object of each commit previously retrieved. f
is never called more than one time for each hash.Value.Tag.t
: f
is called firstly with the OCaml value of the pointed tag by the hash hash
. Then, it follows the git object pointed by the tag.Any retrieved error
is missed.
module Ref : sig ... end
reset t
removes all things of the git repository t
and ensures it will be empty.
read_inflated state hash
returns the inflated git object which respect the predicate digest(value) = hash
. We return the kind of the object and the inflated value as a Cstruct.t
(which the client can take the ownership).
write_inflated state kind raw
writes the git object in the git repository state
and associates the kind to this object. This function does not verify if the raw data is well-defined (and respects the Git format). Then, this function returns the hash produced from the kind and the inflated raw to let the user to retrieve it.
