Issue 3445: amending with --close-branch a commit that created a new head should fail
This shouldn't be possible:
$ hg up -q default
$ hg branch closewithamend
marked working directory as branch closewithamend
(branches are permanent and global, did you want a bookmark?)
$ touch foo
$ hg add foo
$ hg ci -m..
$ hg ci --amend --close-branch -m 'closing'
abort: can only close branch heads
[255]
This silliness fails:
$ hg branch silliness
marked working directory as branch silliness
(branches are permanent and global, did you want a bookmark?)
$ echo b >> b
$ hg ci --close-branch -m'open and close'
abort: can only close branch heads
[255]
Test that amend with --secret creates new secret changeset forcibly
---------------------------------------------------------------------
$ hg phase '.^::.'
35: draft
36: draft
$ hg commit --amend --secret -m 'amend as secret' -q
$ hg phase '.^::.'
35: draft
38: secret
Test that amend with --edit invokes editor forcibly
---------------------------------------------------
$ hg parents --template "{desc}\n"
amend as secret
$ HGEDITOR=cat hg commit --amend -m "editor should be suppressed"
$ hg parents --template "{desc}\n"
editor should be suppressed
$ HGEDITOR=cat hg commit --amend -m "editor should be invoked" --edit
editor should be invoked
HG: Enter commit message. Lines beginning with 'HG:' are removed.
HG: Leave message empty to abort commit.
HG: --
HG: user: test
HG: branch 'silliness'
HG: changed foo
$ hg parents --template "{desc}\n"
editor should be invoked

Setup the repo with a file that gets moved in a second commit.
$ hg init repo
$ cd repo
$ touch a0
$ hg add a0
$ hg commit -m a0
$ hg mv a0 a1
$ hg commit -m a1
$ hg up -q 0
$ hg log -G --template '{rev} {desc}'
o 1 a1
|
@ 0 a0
Now we branch the repro, but re-use the file contents, so we have a divergence
in the file revlog topology and the changelog topology.
$ hg revert --rev 1 --all
removing a0
adding a1
$ hg ci -qm 'a1-amend'
$ hg log -G --template '{rev} {desc}'
@ 2 a1-amend
|
| o 1 a1
|/
o 0 a0
The way mercurial does amends is to create a temporary commit (rev 3) and then
fold the new and old commits together into another commit (rev 4). During this
process, _findlimit is called to check how far back to look for the transitive
closure of file copy information, but due to the divergence of the filelog
and changelog graph topologies, before _findlimit was fixed, it returned a rev
which was not far enough back in this case.
$ hg mv a1 a2
$ hg status --copies --rev 0
A a2
a0
R a0
$ hg ci --amend -q
$ hg log -G --template '{rev} {desc}'
@ 4 a1-amend
|
| o 1 a1
|/
o 0 a0
Before the fix, the copy information was lost.
$ hg status --copies --rev 0
A a2
a0
R a0
