context: move contents of committablectx.markcommitted() to workingctx
Same reasoning as previous commits: this function updates the
dirstate. By not updating the dirstate here, we also fix the
close-head test.

Simple rename case
$ newrepo
$ echo x > x
$ hg ci -Aqm 'add x'
$ hg mv x y
$ hg debugp1copies
x -> y
$ hg debugp2copies
$ hg ci -m 'rename x to y'
$ hg l
@ 1 rename x to y
| x y
o 0 add x
x
$ hg debugp1copies -r 1
x -> y
$ hg debugpathcopies 0 1
x -> y
$ hg debugpathcopies 1 0
y -> x
Test filtering copies by path. We do filtering by destination.
$ hg debugpathcopies 0 1 x
$ hg debugpathcopies 1 0 x
y -> x
$ hg debugpathcopies 0 1 y
x -> y
$ hg debugpathcopies 1 0 y
Copy a file onto another file
$ newrepo
$ echo x > x
$ echo y > y
$ hg ci -Aqm 'add x and y'
$ hg cp -f x y
$ hg debugp1copies
x -> y
$ hg debugp2copies
$ hg ci -m 'copy x onto y'
$ hg l
@ 1 copy x onto y
| y
o 0 add x and y
x y
$ hg debugp1copies -r 1
x -> y
Incorrectly doesn't show the rename
$ hg debugpathcopies 0 1
Copy a file onto another file with same content. If metadata is stored in changeset, this does not
produce a new filelog entry. The changeset's "files" entry should still list the file.
$ newrepo
$ echo x > x
$ echo x > x2
$ hg ci -Aqm 'add x and x2 with same content'
$ hg cp -f x x2
$ hg ci -m 'copy x onto x2'
$ hg l
@ 1 copy x onto x2
| x2
o 0 add x and x2 with same content
x x2
$ hg debugp1copies -r 1
x -> x2
Incorrectly doesn't show the rename
$ hg debugpathcopies 0 1
Copy a file, then delete destination, then copy again. This does not create a new filelog entry.
$ newrepo
$ echo x > x
$ hg ci -Aqm 'add x'
$ hg cp x y
$ hg ci -m 'copy x to y'
$ hg rm y
$ hg ci -m 'remove y'
$ hg cp -f x y
$ hg ci -m 'copy x onto y (again)'
$ hg l
@ 3 copy x onto y (again)
| y
o 2 remove y
| y
o 1 copy x to y
| y
o 0 add x
x
$ hg debugp1copies -r 3
x -> y
$ hg debugpathcopies 0 3
x -> y
Rename file in a loop: x->y->z->x
$ newrepo
$ echo x > x
$ hg ci -Aqm 'add x'
$ hg mv x y
$ hg debugp1copies
x -> y
$ hg debugp2copies
$ hg ci -m 'rename x to y'
$ hg mv y z
$ hg ci -m 'rename y to z'
$ hg mv z x
$ hg ci -m 'rename z to x'
$ hg l
@ 3 rename z to x
| x z
o 2 rename y to z
| y z
o 1 rename x to y
| x y
o 0 add x
x
$ hg debugpathcopies 0 3
Copy x to y, then remove y, then add back y. With copy metadata in the changeset, this could easily
end up reporting y as copied from x (if we don't unmark it as a copy when it's removed).
$ newrepo
$ echo x > x
$ hg ci -Aqm 'add x'
$ hg mv x y
$ hg ci -m 'rename x to y'
$ hg rm y
$ hg ci -qm 'remove y'
$ echo x > y
$ hg ci -Aqm 'add back y'
$ hg l
@ 3 add back y
| y
o 2 remove y
| y
o 1 rename x to y
| x y
o 0 add x
x
$ hg debugp1copies -r 3
$ hg debugpathcopies 0 3
Copy x to z, then remove z, then copy x2 (same content as x) to z. With copy metadata in the
changeset, the two copies here will have the same filelog entry, so ctx['z'].introrev() might point
to the first commit that added the file. We should still report the copy as being from x2.
$ newrepo
$ echo x > x
$ echo x > x2
$ hg ci -Aqm 'add x and x2 with same content'
$ hg cp x z
$ hg ci -qm 'copy x to z'
$ hg rm z
$ hg ci -m 'remove z'
$ hg cp x2 z
$ hg ci -m 'copy x2 to z'
$ hg l
@ 3 copy x2 to z
| z
o 2 remove z
| z
o 1 copy x to z
| z
o 0 add x and x2 with same content
x x2
$ hg debugp1copies -r 3
x2 -> z
$ hg debugpathcopies 0 3
x2 -> z
Create x and y, then rename them both to the same name, but on different sides of a fork
$ newrepo
$ echo x > x
$ echo y > y
$ hg ci -Aqm 'add x and y'
$ hg mv x z
$ hg ci -qm 'rename x to z'
$ hg co -q 0
$ hg mv y z
$ hg ci -qm 'rename y to z'

| o 1 rename x to z

o 0 add x and y

$ hg debugpathcopies 1 2

Fork renames x to y on one side and removes x on the other
$ newrepo
$ echo x > x
$ hg ci -Aqm 'add x'
$ hg mv x y

$ newrepo
$ echo x > x
$ hg ci -Aqm 'add x'
$ hg cp x y
$ hg ci -m 'copy x to y'
$ hg co -q null
$ echo x > x

$ hg ci -Aqm 'add z'

Perhaps we should indicate the rename here, but `hg status` is documented to be weird during
merges, so...
