Field Detail

pending

private final FIFORevQueue pending

depth

private final int depth

deepenSince

private final int deepenSince

walk

private final RevWalk walk

UNSHALLOW

private final RevFlag UNSHALLOW

Commits which used to be shallow in the client, but which are being extended as part of this fetch. These commits should be returned to the caller as UNINTERESTING so that their blobs/trees can be marked appropriately in the pack writer.

REINTERESTING

private final RevFlag REINTERESTING

Commits which the normal framework has marked as UNINTERESTING, but which we now care about again. This happens if a client is extending a shallow checkout to become deeper--the new commits at the bottom of the graph need to be sent, even though they are below other commits which the client already has.

DEEPEN_NOT

private final RevFlag DEEPEN_NOT

Commits reachable from commits that the client specified using --shallow-exclude.
