Better way to set the parent to an ancestor change set and get the content of the tip

The best way I found was:

hg update -r0 -C #ancestor rev 0
hg revert -r tip --all

To illustrate the situation a bit:

hg init
echo "init" > a.txt
hg commit -A -m“init” a.txt #rev 0

echo "hello" > a.txt
hg commit -m"change"

hg update -r0 -C
hg revert -r tip --all

The interestin开发者_StackOverflow社区g properties are hg diff -r tip is empty and hg parent is changeset: 0.

You can do that like this, but don't tell anyone:

hg debugsetparent 0

you might need to also do hg debugrebuildstate for the hg stat command to realize you pulled a switcharoo on it.

You didn't hear it from me though. :)
