changegroup: move close() from narrow More of the same. Differential Revision: https://phab.mercurial-scm.org/D4064

changegroup: move revchunk() from narrow The monkeypatched revchunk for ellipses serving is a completely independent implementation. We model it as such in the changegroup code. revchunk() is now a simple proxy function. Again, I wish we had better APIs here. Especially since this narrow code is part of cg1packer and cg1packer can't be used with narrow. Class inheritance is wonky. And I will definitely be making changes to changegroup code for delta generation. As part of the code move, `node.nullrev` was replaced by `nullrev`. And a reference to `orig` was replaced to call `self._revchunknormal` directly. Differential Revision: https://phab.mercurial-scm.org/D4063

changegroup: move deltaparent() from narrow I'm not keen on performing the attribute sniff to test for presence of ellipses mode: I'd rather we use a separate packer instance that was ellipses mode specific. But I've tried to formalize a better API without narrow in core and I can't make sense of all the monkeypatching. My goal is to inline as much of the monkeypatching as possible then refactor the changegroup generation API. We add this code to the cg2packer because narrow doesn't work with cg1.

changegroup: move _packellipsischangegroup() from narrow The behavior here is not ideal, as the function constructs a packer then adds attributes to it. This will be cleaned up in subsequent commits. Moving this code is necessary to move the remainder of the bundle2-level changegroup part generation code into core. Differential Revision: https://phab.mercurial-scm.org/D4061

changegroup: move ellipsisdata() from narrow This is a pretty straightforward copy of the function. Differential Revision: https://phab.mercurial-scm.org/D4060

fileset: narrow status computation by left-hand-side of 'and' node Timing with warm disk cache: $ hg status --cwd mozilla-central 'set:path:build/ and unknown()' --time (orig) time: real 1.970 secs (user 1.560+0.000 sys 0.410+0.000) (new) time: real 0.330 secs (user 0.310+0.000 sys 0.020+0.000)

fileset: move copy constructor of matchctx near __init__

fileset: build status according to 'withstatus' hint _switchcallers is no longer needed since 'withstatus' node is reinserted for arguments of functions like revs(). New matchctx instance is created per 'withstatus' to make sure that status tuple is available only for children of the 'withstatus' node.
