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.

fileset: insert hints where status should be computed This will allow us to compute status against a narrowed set of files. For example, "path:build/ & (unknown() + missing())" is rewritten as "path:build/ & <withstatus>(unknown() + missing(), 'unknown missing')", and the status call can be narrowed by the left-hand-side matcher, "path:build/". mctx.buildstatus() calls will be solely processed by getmatchwithstatus().

fileset: move buildstatus() to matchctx method In future patches, file status will be computed while evaluating a parsed tree. This patch provides a matchctx interface to build status.

fileset: keep basectx by matchctx

fileset: pass in basectx to _buildstatus() I'll make matchctx remember both ctx and basectx so that file status between them can be computed later. This prepares for the change.

resolve: update commands.resolve.confirm help text Included --mark and --unmark in the help text of resolve.confirm.config. Differential Revision: https://phab.mercurial-scm.org/D4103

resolve: support confirm config option with --unmark flag Now, commands.resolve.confirm also respect --unmark option; and confirm to unresolve all resolved files. It will confirm only when no files pats are passed (same as --mark), because when no pats are passed the default is to mark resolved files as unresolved. And if user has passed file pats then I think there is no need to confirm for that. Differential Revision: https://phab.mercurial-scm.org/D4102

narrow: move .hg/narrowspec to .hg/store/narrowspec (BC) The narrowspec is more closely related to the store than to the working copy. For example, if the narrowspec changes, the set of revlogs also needs to change (the working copy may change, but that depends on which commit is checked out). Also, when using the share extension, the narrowspec needs to be shared along with the store. This patch therefore moves the narrowspec into the store/ directory. This is clearly a breaking change, but I haven't bothered trying to fall back to reading the narrowspec from the old location (.hg/), because there are very few users of narrow out there. (We'll add a temporary hack to our Google-internal extension to handle the migration.) Differential Revision: https://phab.mercurial-scm.org/D4099
