rebase: extract _assignworkingcopy Slightly cleaner, and makes it easier to hook this in an extension. Differential Revision: https://phab.mercurial-scm.org/D1617

rebase: disable `inmemory` if the rebaseset contains the working copy As described in the comment, rebasing the working copy parent with in-memory merge, and then updating to the new commit, isn't much faster because of the extra overhead of uppdating. Best to leave it off in that case. This commit makes deploying in-memory merge via an extension easier, because you can just set `inmemory=True` based on some config or probability, and this will turn off the cases where it's not desired.

clone: add support for storing remotenames while cloning If `experimental.remotenames` is set to True, we store the remotenames in case of `hg pull`. This patch adds that support to clone command also. Differential Revision: https://phab.mercurial-scm.org/D1601

revset: use phasecache.getrevset to calculate public() Other revsets like secret(), draft(), _nonpublic() are using phasescache.getrevset already. The latter is more efficient after D1606. So let's migrate the public() revset function too. Tested using: $ hg debugshell --hidden --cwd hg-committed` In [1]: %timeit len(repo.revs('public()')) * Before D1606: 10 loops, best of 3: 22.5 ms per loop * Before this change, after D1606: 10 loops, best of 3: 28.6 ms per loop * After this change: 10 loops, best of 3: 20.2 ms per loop Therefore `public()` revset becomes even slightly faster after the data structure change by D1606. A similar performance win could also be observed on a large repo. A side effect is `phasecache.getrevset` needs to take a `subset` parameter. That was added with a default value so it won't cause BC issues. Differential Revision: https://phab.mercurial-scm.org/D1620

highlight: eagerly discover plugin lexers while demandimport is off Since highlight is only relevant for servers, it seems worthwhile to just trigger this eagerly, which avoids really weird traceback problems caused by demandimport messing with some of the lexer plugins.

patch: move part of tabsplitter logic in _inlinediff It cannot be entirely moved within _inlinediff as long as worddiff is experimental (when turned off, matches is always an empty dict).

overlayworkingctx: invalidate the manifest cache when changing parents This fixes problems noticeable when rebasing several commits into one destination commit using ``--collapse``. The manifest cache needs to be cleared each time. Differential Revision: https://phab.mercurial-scm.org/D1244

overlayworkingctx: add `_compact()` Alas, presence of a key in the cache isn't sufficient evidence that the file is actually dirty. Differential Revision: https://phab.mercurial-scm.org/D1243

overlayworkingctx: add ``tomemctx()`` Differential Revision: https://phab.mercurial-scm.org/D1242

overlayworkingctx: add _auditconflicts to write() Alas, part of Mercurial's conflict detection (for file<->folder conflicts, for example) depends on the filesystem. We don't have the filesystem with IMM, so we have to run these checks ourselves. Differential Revision: https://phab.mercurial-scm.org/D1241
