git-http-push
(1)Push objects over HTTP/DAV to another repository
Options
5--allDo not assume that the remote repository is complete in its current state, and verify all objects in the entire local ref’s history exist in the remote repository.
--forceUsually, the command refuses to update a remote ref that is not an ancestor of the local ref used to overwrite it. This flag disables the check. What this means is that the remote repository can lose commits; use it with care.
--dry-runDo everything except actually send the updates.
--verboseReport the list of objects being walked locally and the list of objects successfully sent to the remote repository.
-d-DRemove <ref> from remote repository. The specified branch cannot be the remote HEAD. If -d is specified, the following other conditions must also be met: •Remote HEAD must resolve to an object that exists locally •Specified branch resolves to an object that exists locally •Specified branch is an ancestor of the remote HEAD
DESCRIPTION
SPECIFYING THE REFS
A <ref> specification can be either a single pattern, or a pair of such patterns separated by a colon ":" (this means that a ref name cannot have a colon in it). A single pattern <name> is just a shorthand for <name>:<name>.
Each pattern pair <src>:<dst> consists of the source side (before the colon) and the destination side (after the colon). The ref to be pushed is determined by finding a match that matches the source side, and where it is pushed is determined by using the destination side.
Without ‘--force`, the <src> ref is stored at the remote only if <dst> does not exist, or <dst> is a proper subset (i.e. an ancestor) of <src>. This check, known as "fast-forward check", is performed to avoid accidentally overwriting the remote ref and losing other peoples’ commits from there.
With --force, the fast-forward check is disabled for all refs.
Optionally, a <ref> parameter can be prefixed with a plus + sign to disable the fast-forward check only on that ref.
