but forgot to mention he was using mtn 1.0:
I checked out a new workspace, and I want to check it in again unchenged
with a new branch name -- the one I want to use to make changes. I'd
like to make it clear that the new branch is starting in the same state
as the current head in the old one.
I use this:
function gds_create_mission(mission, from_branch, new_branch)
local from_project, new_project, result, output, rev
from_project = mission .. "." .. from_branch
new_project = mission .. "." .. new_branch
io.write("checking ...\n")
result, output = mtn_automate("branches")
if not result then
error(string.format("Error from 'mtn_automate branches %s'", output))
end
if string.find (output, new_project) then
error(string.format("%s branch already declared", new_project))
end
result, output = mtn_automate("heads", from_project)
if not result then
error(string.format("Error from 'mtn_automate heads %s'", from_project))
end
-- A single head gives an output with a single 40 byte rev id,
plus newline.
if #output > 41 then
error(string.format("%s has multiple heads; need merge", from_project))
end
io.write(string.format("creating %s from %s\n", new_project, from_project))
result, output = mtn_automate("select", "h:" .. from_project)
if not result then
error(string.format("Error from 'mtn_automate select %s'", "h:"
.. from_project))
end
rev = string.sub(output, 1, 40)
result, output = mtn_automate("cert", rev, "branch", new_project)
if not result then
error(string.format("Error from 'mtn_automate cert %s branch %s
: %s'", rev, new_project, output))
end
end
register_command("gds_create_mission", "mission from_branch
new_branch", "create mtn branch for a GDS mission",
"Create mtn branch derived from FROM_BRANCH, in MISSION.",
"gds_create_mission")
The key command is "automate cert"; just add the new branch cert to
the existing revision.
There have been discussions before about making something like this
part of mtn, but nothing has been agreed on.
