snapshot: consider all snapshots in the parents' chains There are no reasons to only consider full snapshot as a possible base for an intermediate snapshot. Now that the basic principles have been set, we can start adding more levels of snapshots. We now consider all snapshots in the parent's chains (full or intermediate). This creates a chain of intermediate snapshots, each smaller than the previous one. # Effect On The Test Repository In the test repository, we can see a decrease in the revlog size and slightly shorter delta chain. However, that approach creates snapshots more frequently, increasing the risk of ending into problematic cases in very branchy repositories (not triggered by the test repository). The next changesets will remove that risk by adding logic that increases deltas reuse.

# A portable replacement for 'seq'

# Usage:
#   seq STOP              [1, STOP] stepping by 1
#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP
