PushProcess

PushProcess(Transport transport,
            java.util.Collection<RemoteRefUpdate> toPush,
            PrePushHook prePush)
     throws TransportException

Create process for specified transport and refs updates specification.

Parameters:

transport - transport between remote and local repository, used to create connection.

toPush - specification of refs updates (and local tracking branches).

prePush - PrePushHook to run after the remote advertisement has been gotten

Throws:

TransportException

PushProcess

PushProcess(Transport transport,
            java.util.Collection<RemoteRefUpdate> toPush,
            PrePushHook prePush,
            java.io.OutputStream out)
     throws TransportException

Create process for specified transport and refs updates specification.

Parameters:

transport - transport between remote and local repository, used to create connection.

toPush - specification of refs updates (and local tracking branches).

prePush - PrePushHook to run after the remote advertisement has been gotten

out - OutputStream to write messages to

Throws:

TransportException

Method Detail

execute

PushResult execute(ProgressMonitor monitor)
            throws NotSupportedException,
                   TransportException

Perform push operation between local and remote repository - set remote refs appropriately, send needed objects and update local tracking refs.

When Transport.isDryRun() is true, result of this operation is just estimation of real operation result, no real action is performed.

Parameters:

monitor - progress monitor used for feedback about operation.

Returns:

result of push operation with complete status description.

Throws:

NotSupportedException - when push operation is not supported by provided transport.

TransportException - when some error occurred during operation, like I/O, protocol error, or local database consistency error.

prepareRemoteUpdates

private java.util.Map<java.lang.String,RemoteRefUpdate> prepareRemoteUpdates()
                                                                            throws TransportException

Throws:

TransportException

isFastForward

private boolean isFastForward(ObjectId oldOid,
                              ObjectId newOid)
                       throws TransportException

Determines whether an update from oldOid to newOid is a fast-forward update:

• both old and new must be commits, AND
• both of them must be known to us and exist in the repository, AND
• the old commit must be an ancestor of the new commit.

Parameters:

oldOid - ObjectId of the old commit

newOid - ObjectId of the new commit

Returns:

true if the update fast-forwards, false otherwise

Throws:

TransportException

expandMatching

private java.util.Map<java.lang.String,RemoteRefUpdate> expandMatching()
                                                                      throws TransportException

Expands all placeholder RemoteRefUpdates for "matching" RefSpecs ":" in toPush and returns the resulting map in which the placeholders have been replaced by their expansion.

Returns:

a new map of RemoteRefUpdates keyed by remote name

Throws:

TransportException - if the expansion results in duplicate updates

expandMatching

private void expandMatching(java.util.Map<java.lang.String,RemoteRefUpdate> updates,
                            RemoteRefUpdate match)
                     throws TransportException

Expands the placeholder RemoteRefUpdate match for a "matching" RefSpec ":" or "+:" and puts the expansion into the given map updates.

Parameters:

updates - map to put the expansion in

match - the placeholder RemoteRefUpdate to expand

Throws:

TransportException - if the expansion results in duplicate updates, or the local branches cannot be determined

rejectAll

private java.util.Map<java.lang.String,RemoteRefUpdate> rejectAll()

modifyUpdatesForDryRun

private void modifyUpdatesForDryRun()

updateTrackingRefs

private void updateTrackingRefs()

getPushOptions

public java.util.List<java.lang.String> getPushOptions()

Gets the list of option strings associated with this push.

Returns:

pushOptions
