Instance Method Details

#check_connection(direction, options = {}) ⇒ Boolean

Try to connect to the remote. Useful to simulate git fetch --dry-run and git push --dry-run.

Returns true if connection is successful, false otherwise.

direction must be either :fetch or :push.

The following options can be passed in the options Hash:

credentials

The credentials to use for the connection. Can be either an instance of one of the Rugged::Credentials types, or a proc returning one of the former. The proc will be called with the url, the username from the url (if applicable) and a list of applicable credential types.

:headers

Extra HTTP headers to include with the request (only applies to http:// or https:// remotes)

:proxy_url

The url of an http proxy to use to access the remote repository.

Example:

remote = repo.remotes["origin"]
success = remote.check_connection(:fetch)
raise Error("Unable to pull without credentials") unless success

Returns:

• (Boolean)

#fetch(refspecs = nil, options = {}) ⇒ Hash

Downloads new data from the remote for the given refspecs and updates tips.

You can optionally pass in a single or multiple alternative refspecs to use instead of the fetch refspecs already configured for remote.

Returns a hash containing statistics for the fetch operation.

The following options can be passed in the options Hash:

:credentials

The credentials to use for the fetch operation. Can be either an instance of one of the Rugged::Credentials types, or a proc returning one of the former. The proc will be called with the url, the username from the url (if applicable) and a list of applicable credential types.

:headers

Extra HTTP headers to include with the request (only applies to http:// or https:// remotes)

:progress

A callback that will be executed with the textual progress received from the remote. This is the text send over the progress side-band (ie. the “counting objects” output).

:transfer_progress

A callback that will be executed to report clone progress information. It will be passed the amount of total_objects, indexed_objects, received_objects, local_objects, total_deltas, indexed_deltas and received_bytes.

:update_tips

A callback that will be executed each time a reference is updated locally. It will be passed the refname, old_oid and new_oid.

:certificate_check

A callback that will be executed each time we validate a certificate using https. It will be passed the valid, host_name and the callback should return a true/false to indicate if the certificate has been validated.

:message

The message to insert into the reflogs. Defaults to “fetch”.

:prune

Specifies the prune mode for the fetch. true remove any remote-tracking references that no longer exist, false do not prune, nil use configured settings Defaults to “nil”.

:proxy_url

The url of an http proxy to use to access the remote repository.

Example:

remote = Rugged::Remote.lookup(@repo, 'origin')
remote.fetch({
  transfer_progress: lambda { |total_objects, indexed_objects, received_objects, local_objects, total_deltas, indexed_deltas, received_bytes|
    # ...
  }
})

Returns:

#ls(options = {}) ⇒ Object #ls(options = ) { ... } ⇒ Object

Connects remote to list all references available along with their associated commit ids.

The given block is called once for each remote head with a Hash containing the following keys:

:local?

true if the remote head is available locally, false otherwise.

:oid

The id of the object the remote head is currently pointing to.

:loid

The id of the object the local copy of the remote head is currently pointing to. Set to nil if there is no local copy of the remote head.

:name

The fully qualified reference name of the remote head.

If no block is given, an enumerator will be returned.

The following options can be passed in the options Hash:

:credentials

The credentials to use for the ls operation. Can be either an instance of one of the Rugged::Credentials types, or a proc returning one of the former. The proc will be called with the url, the username from the url (if applicable) and a list of applicable credential types.

:headers

Extra HTTP headers to include with the request (only applies to http:// or https:// remotes)

:proxy_url

The url of an http proxy to use to access the remote repository.
