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.

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' $ hg l @ 2 rename y to z | y z | o 1 rename x to z |/ x z o 0 add x and y x y $ hg debugpathcopies 1 2 z -> x y -> z 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 $ hg ci -m 'rename x to y' $ hg co -q 0 $ hg rm x $ hg ci -m 'remove x' created new head $ hg l @ 2 remove x | x | o 1 rename x to y |/ x y o 0 add x x $ hg debugpathcopies 1 2 Copies via null revision (there shouldn't be any) $ 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 x (again)' $ hg l @ 2 add x (again) x o 1 copy x to y | y o 0 add x x $ hg debugpathcopies 1 2 $ hg debugpathcopies 2 1 Merge rename from other branch $ newrepo $ echo x > x $ hg ci -Aqm 'add x' $ hg mv x y $ hg ci -m 'rename x to y' $ hg co -q 0 $ echo z > z $ hg ci -Aqm 'add z' $ hg merge -q 1 $ hg debugp1copies $ hg debugp2copies $ hg ci -m 'merge rename from p2' $ hg l @ 3 merge rename from p2 |\ x | o 2 add z | | z o | 1 rename x to y |/ x y o 0 add x x Perhaps we should indicate the rename here, but `hg status` is documented to be weird during merges, so... $ hg debugp1copies -r 3 $ hg debugp2copies -r 3 $ hg debugpathcopies 0 3 x -> y $ hg debugpathcopies 1 2 y -> x $ hg debugpathcopies 1 3 $ hg debugpathcopies 2 3 x -> y Copy file from either side in a merge $ newrepo $ echo x > x $ hg ci -Aqm 'add x' $ hg co -q null $ echo y > y $ hg ci -Aqm 'add y' $ hg merge -q 0 $ hg cp y z $ hg debugp1copies y -> z $ hg debugp2copies $ hg ci -m 'copy file from p1 in merge' $ hg co -q 1 $ hg merge -q 0 $ hg cp x z $ hg debugp1copies $ hg debugp2copies x -> z $ hg ci -qm 'copy file from p2 in merge' $ hg l @ 3 copy file from p2 in merge |\ z +---o 2 copy file from p1 in merge | |/ z | o 1 add y | y o 0 add x x $ hg debugp1copies -r 2 y -> z $ hg debugp2copies -r 2 $ hg debugpathcopies 1 2 y -> z $ hg debugpathcopies 0 2 $ hg debugp1copies -r 3 $ hg debugp2copies -r 3 x -> z $ hg debugpathcopies 1 3 $ hg debugpathcopies 0 3 x -> z Copy file that exists on both sides of the merge, same content on both sides $ newrepo $ echo x > x $ hg ci -Aqm 'add x on branch 1' $ hg co -q null $ echo x > x $ hg ci -Aqm 'add x on branch 2' $ hg merge -q 0 $ hg cp x z $ hg debugp1copies x -> z $ hg debugp2copies $ hg ci -qm 'merge' $ hg l @ 2 merge |\ z | o 1 add x on branch 2 | x o 0 add x on branch 1 x $ hg debugp1copies -r 2 x -> z $ hg debugp2copies -r 2 It's a little weird that it shows up on both sides $ hg debugpathcopies 1 2 x -> z $ hg debugpathcopies 0 2 x -> z (filelog !)
