test-strip-cross: test handling of linkrev crosses in the manifest

Fix test-strip-cross on Solaris Solaris /sbin/sh doesn't do brace expansion

simplify revlog.strip interface and callers; add docstring Also, strip files only after the changelog and the manifest.

strip: calculate list of extra nodes to save and pass it to changegroupsubset When we remove revision N from the repository, all revisions >= N are affected: either it's a descendant from N and will also be removed, or it's not a descendant of N and will be renumbered. As a consequence, we have to (at least temporarily) remove all filelog and manifest revisions that have a linkrev >= N, readding some of them later. Unfortunately, it's possible to have a revlog with two revisions r1 and r2 such that r1 < r2, but linkrev(r1) > linkrev(r2). If we try to strip revision linkrev(r1) from the repository, we'll also lose revision r2 when we truncate this revlog. We already use changegroupsubset to create a temporary changegroup containing the revisions that have to be restored, but that function is unable to detect that we also wanted to save the r2 in the case above. So we manually calculate these extra nodes and pass it to changegroupsubset. This should fix issue764.

changegroupsubset: accept list of per-revlog nodes to include This will allow strip to include in the temporary changegroup some extra file/manifest revisions that should be restored after the truncations. This code doesn't allow specification of changelog nodes since I won't need that right now, the code wouldn't be tested and it's probably possible to do something similar enough by using the bases/heads arguments.

addchangegroup: add option to skip check for empty changelog group

allow the creation of bundles with empty changelog/manifest chunks
