manifest: add manifestlog.add This adds a simple add() function to manifestlog. This lets us convert more uses of repo.manifest to use repo.manifestlog, so we can further break our dependency on the manifest class.

manifest: move manifest.add onto manifestrevlog This moves add and _addtree onto manifestrevlog. manifestrevlog is responsible for all serialization decisions, so therefore the add function should live on it. This will allow us to call add() from manifestlog, which lets us further break our dependency on manifest.

manifest: remove dependency on treeinmem from manifest.add Currently manifest.add uses the treeinmem option to know if it can call fastdelta on the given manifest instance. In a future patch we will be moving add() to be on the manifestrevlog, so it won't have access to the treeinmem option anymore. Instead, let's have it actually check if the given manifest instance supports the fastdelta operation. This also means that if treemanifest or any implementation eventually implements fastdelta(), it will automatically benefit from this code path.

manifest: move treeinmem onto manifestlog A previous patched moved all the serialization related options onto manifestrevlog (since it is responsible for serialization). Let's move the treeinmem option on manifestlog, since it is responsible for materialization decisions. This reduces the number of dependencies manifestlog has on the old manifest type as well, so we can eventually make them completely independent of each other.

copy: document current behavior of 'hg cp --after' I'm about to propose an output change here, but the existing behavior was untested!

crecord: add an event that scrolls the selected line to the top of the screen Using ctrl-l for this purpose seems to be a fairly widely used practice, presumably following emacs. This doesn't scroll the selected line all the way to the top of the window, instead it leaves a 3 line buffer for context. Use curses.unctrl() to resolve keypressed to '^L' to avoid hard-coding hexadecimal key codes.

log: drop hack to fix order of revset (issue5100) Specify ordered=revset.followorder instead. This patch effectively backs out c407583cf5f6. revs.sort(reverse=True) is replaced by revs.reverse() because the matcher should no longer reorder revisions.

revset: add option to make matcher takes the ordering of the input set This allows us to evaluate match(subset) as if 'subset & expr', which will be the complete fix for the issue5100.

strip: don't use "full" and "partial" to describe bundles The partial bundle is not a subset of the full bundle, and the full bundle is not full in any way that i see. The most obvious interpretation of "full" I can think of is that it has all commits back to the null revision, but that is not what the "full" bundle is. The "full" bundle is simply a backup of what the user asked us to strip (unless --no-backup). The "partial" bundle contains the revisions we temporarily stripped because they had higher revision numbers that some commit that the user asked us to strip. The "full" bundle is already called "backup" in the code, so let's use that in user-facing messages too. Let's call the "partial" bundle "temporary" in the code.

strip: clarify that user action is required to recover temp bundle If strip fails when applying the temporary bundle, the commits in the temporary bundle have not yet been applied, so the user will almost definitely want to apply the bundle. We should be more clear to the user about that than our current "partial bundle stored in...". Note that we will probably not be able to recover it automatically, since whatever made it fail (e.g. a hook) will most likely make it fail again. We need to give control back to the user to fix the problem before trying again.
