Default (and first pass) RevCommit Generator implementation for RevWalk.

This generator starts from a set of one or more commits and process them in descending (newest to oldest) commit time order. Commits automatically cause their parents to be enqueued for further processing, allowing the entire commit graph to be walked. A RevFilter may be used to select a subset of the commits and return them to the caller.

pack-priv boolean canDispose
filterback to summary
private final RevFilter filter
INIT_LASTback to summary
private static final RevCommit INIT_LAST

A commit near the end of time, to initialize last with.

OVER_SCANback to summary
pack-priv static final int OVER_SCAN

Number of additional commits to scan after we think we are done.

This small buffer of commits is scanned to ensure we didn't miss anything as a result of clock skew when the commits were made. We need to set our constant to 1 additional commit due to the use of a pre-increment operator when accessing the value.

overScanback to summary
private int overScan

Number of commits we have remaining in our over-scan allotment.

Only relevant if there are UNINTERESTING commits in the pending queue.
