Create a backend from a VCS implementation.
Parameters
Signature
val name : OpamUrl.backendval pull_url :
?cache_dir:OpamTypes.dirname ->
?subpath:OpamTypes.subpath ->
OpamTypes.dirname ->
OpamHash.t option ->
OpamTypes.url ->
OpamTypes.filename option OpamTypes.download OpamProcess.jobpull_url local_dir checksum remote_url pulls the contents of remote_url into local_dir.
Two kinds of results are allowed:
- a single file was downloaded, in this case it is placed within
local_dirand returned asSome filename
- a directory was retrieved, in this case the contents of
local_dirhave been synchronised with its own, andNoneis returned
checksum can be used for retrieval but is NOT checked by this function.
val fetch_repo_update :
OpamTypes.repository_name ->
?cache_dir:OpamTypes.dirname ->
OpamTypes.dirname ->
OpamTypes.url ->
OpamRepositoryBackend.update OpamProcess.jobpull_repo_update fetches the remote update from url to the local repository at dirname, but does not apply it, allowing for further verifications. The file or directory returned is always temporary and should be cleaned up by the caller.
val repo_update_complete :
OpamTypes.dirname ->
OpamTypes.url ->
unit OpamProcess.jobrepo_update_complete dirname url finalizes the update of the repository after verification of the patch returned from pull_repo_update with Update_patch file is applied. Version control systems, e.g. Mercurial, that track the state of the working directory automatically use this to update internal caches.
val revision : OpamTypes.dirname -> OpamTypes.version option OpamProcess.jobReturn the (optional) revision of a given repository. Only useful for VCS backends. Is not expected to work with pull_repo_update, which doesn't update the VCS commit information.
val sync_dirty :
?subpath:OpamTypes.subpath ->
OpamTypes.dirname ->
OpamTypes.url ->
OpamTypes.filename option OpamTypes.download OpamProcess.jobLike pull_url, except for locally-bound version control backends, where it should get the latest, uncommitted source. First, it performs a pull_url, then remove deleted files, and finally copy via rsync unversioned & modified-uncommitted files.
val get_remote_url :
?hash:string ->
OpamTypes.dirname ->
OpamTypes.url option OpamProcess.jobget_remote_url ?hash dirname return the distant url of repo dirname, \ if found. When hash is specified, it checks that this hash (branch or \ commit) is present in the distant repository and returns the url with \ this hash. If the hash is absent it returns the remote url with no hash.
