"Whether to favor remote upstreams when creating new branches.
|
||
|
|
|
||
|
|
When a new branch is created, then the branch, commit, or stash
|
||
|
|
at point is suggested as the default starting point of the new
|
||
|
|
branch, or if there is no such revision at point the current
|
||
|
|
branch. In either case the user may choose another starting
|
||
|
|
point.
|
||
|
|
|
||
|
|
If the chosen starting point is a branch, then it may also be set
|
||
|
|
as the upstream of the new branch, depending on the value of the
|
||
|
|
Git variable `branch.autoSetupMerge'. By default this is done
|
||
|
|
for remote branches, but not for local branches.
|
||
|
|
|
||
|
|
You might prefer to always use some remote branch as upstream.
|
||
|
|
If the chosen starting point is (1) a local branch, (2) whose
|
||
|
|
name matches a member of the value of this option, (3) the
|
||
|
|
upstream of that local branch is a remote branch with the same
|
||
|
|
name, and (4) that remote branch can be fast-forwarded to the
|
||
|
|
local branch, then the chosen branch is used as starting point,
|
||
|
|
but its own upstream is used as the upstream of the new branch.
|
||
|
|
|
||
|
|
Members of this option's value are treated as branch names that
|
||
|
|
have to match exactly unless they contain a character that makes
|
||
|
|
them invalid as a branch name. Recommended characters to use
|
||
|
|
to trigger interpretation as a regexp are \"*\" and \"^\". Some
|
||
|
|
other characters which you might expect to be invalid, actually
|
||
|
|
are not, e.g. \".+$\" are all perfectly valid. More precisely,
|
||
|
|
if `git check-ref-format --branch STRING' exits with a non-zero
|
||
|
|
status, then treat STRING as a regexp.
|
||
|
|
|
||
|
|
Assuming the chosen branch matches these conditions you would end
|
||
|
|
up with with e.g.:
|
||
|
|
|
||
|
|
feature --upstream--> origin/master
|
||
|
|
|
||
|
|
instead of
|
||
|
|
|
||
|
|
feature --upstream--> master --upstream--> origin/master
|
||
|
|
|
||
|
|
Which you prefer is a matter of personal preference. If you do
|
||
|
|
prefer the former, then you should add branches such as \"master\",
|
||
|
|
\"next\", and \"maint\" to the value of this options."

"Alist of upstreams to be used when branching from remote branches.
|
||
|
|
|
||
|
|
When creating a local branch from an ephemeral branch located
|
||
|
|
on a remote, e.g. a feature or hotfix branch, then that remote
|
||
|
|
branch should usually not be used as the upstream branch, since
|
||
|
|
the push-remote already allows accessing it and having both the
|
||
|
|
upstream and the push-remote reference the same related branch
|
||
|
|
would be wasteful. Instead a branch like \"maint\" or \"master\"
|
||
|
|
should be used as the upstream.
|
||
|
|
|
||
|
|
This option allows specifying the branch that should be used as
|
||
|
|
the upstream when branching certain remote branches. The value
|
||
|
|
is an alist of the form ((UPSTREAM . RULE)...). The first
|
||
|
|
element is used whose UPSTREAM exists and whose RULE matches
|
||
|
|
the name of the new branch. Subsequent elements are ignored.
|
||
|
|
|
||
|
|
UPSTREAM is the branch to be used as the upstream for branches
|
||
|
|
specified by RULE. It can be a local or a remote branch.
|
||
|
|
|
||
|
|
RULE can either be a regular expression, matching branches whose
|
||
|
|
upstream should be the one specified by UPSTREAM. Or it can be
|
||
|
|
a list of the only branches that should *not* use UPSTREAM; all
|
||
|
|
other branches will. Matching is done after stripping the remote
|
||
|
|
part of the name of the branch that is being branched from.
|
||
|
|
|
||
|
|
If you use a finite set of non-ephemeral branches across all your
|
||
|
|
repositories, then you might use something like:
|
||
|
|
|
||
|
|
((\"origin/master\" . (\"master\" \"next\" \"maint\")))
|
||
|
|
|
||
|
|
Or if the names of all your ephemeral branches contain a slash,
|
||
|
|
at least in some repositories, then a good value could be:
|
||
|
|
|
||
|
|
((\"origin/master\" . \"/\"))
|
||
|
|
|
||
|
|
Of course you can also fine-tune:
|
||
|
|
|
||
|
|
((\"origin/maint\" . \"\\\\\\=`hotfix/\")
|
||
|
|
(\"origin/master\" . \"\\\\\\=`feature/\"))
|
||
|
|
|
||
|
|
UPSTREAM can be a local branch:
|
||
|
|
|
||
|
|
((\"master\" . (\"master\" \"next\" \"maint\")))
|
||
|
|
|
||
|
|
Because the main branch is no longer almost always named \"master\"
|
||
|
|
you should also account for other common names:
|
||
|
|
|
||
|
|
((\"main\" . (\"main\" \"master\" \"next\" \"maint\"))
|
||
|
|
(\"master\" . (\"main\" \"master\" \"next\" \"maint\")))
|
||
|
|
|
||
|
|
If you use remote branches as UPSTREAM, then you might also want
|
||
|
|
to set `magit-branch-prefer-remote-upstream' to a non-nil value.
|
||
|
|
However, I recommend that you use local branches as UPSTREAM."

it shares with its upstream. If the current branch has no

the commit that is the fewest commits ahead of the source

The commit at the other end of the selection actually does not
