swhid_core 0.1 · OCaml Package

A functor that, given a SHA1 module and a OS module, provides various functions to compute the swhid of a given object. Supported objects are content, directory, release, revision and snapshot. The origins and visits objects are not supported.

Parameters

module SHA1 : sig ... end

module OS : sig ... end

Signature

type directory_entry = {

typ : directory_entry_kind;
permissions : int;
name : string;
target : Object.Core_identifier.t;

}

The type for directory entries list, needed to compute directories identifiers.

type date = {

timestamp : Int64.t;
tz_offset : int;
negative_utc : bool;

}

The type for dates, needed to compute releases and revisions identifiers.

val content_identifier : string -> (Object.t, string) result

content_identifier s computes the swhid for the s content. s is the raw content of a file as a string.

E.g. content_identifier "_build\n" is the swhid of this library's .gitignore file.

val directory_identifier : directory_entry list -> (Object.t, string) result

directory_identifier entries compute the swhid for the entries directory. entries is a list of Kinds.directory_entry where each element points to another object (usually a file content or a sub-directory).

E.g. directory_identifier [ { typ = "file" ; permissions = 33188 ; name = "README" ; target = "37ec8ea2110c0b7a32fbb0e872f6e7debbf95e21" }] is the swhid of a directory which has a single file README with permissions 33188 and whose core identifier from content_identifier is 37ec8ea2110c0b7a32fbb0e872f6e7debbf95e21.

val directory_identifier_deep : string -> (Object.t, string) result

directory_identifier_deep compute the swhid for a given directory name, it uses the various functions provided in the OS module parameter to list directory contents, get file permissions and read file contents.

val release_identifier : 
  Object.Hash.t ->
  Object.Kind.t ->
  name:string ->
  author:string option ->
  date option ->
  message:string option ->
  (Object.t, string) result

release_identifier target target_kind name ~author date ~message computes the swhid for a release object pointing to an object of type target_kind whose identifier is target, the release having ~name, ~author and has been published on date with the release ~message.

val revision_identifier : 
  Object.Hash.t ->
  Object.Hash.t list ->
  author:string ->
  author_date:date option ->
  committer:string ->
  committer_date:date option ->
  (string * string) array ->
  message:string option ->
  (Object.t, string) result

revision dir parents ~author ~author_date ~committer ~committer_date extra_headers message computes the swhid for a revision object whose directory has id dir and whose parents has ids parents which was authored by ~author on ~author_date and committed by ~committer on ~committer_date with extra headers extra_headers and message message.

val snapshot_identifier : 
  (string * (string * string) option) list ->
  (Object.t, string) result

snapshot_identifier branches computes the swhid of the snapshot made of branches branches where branches is a list of branch elements. Each branch is of the form name, target where name is the name of the branch and where target is a pair made of the identifier of the branch and its type.
