Why find parent_location in post_change_branch_tip hook?

[Eugene Tarasenko]

After run branch command in post_change_branch_tip hook params.branch.get_parent() == None.
Why define source path in this hook?

[Martin Pool (mbp)]

Can you be more clear about what you want/expect?

[Eugene Tarasenko (etarasenko)]

I need to define the branch.parent being in hook post_change_branch_tip, but this always == None.

The simplified scheme in Bazaar source:

call hook
set parent

I need:

set parent
call hook
