While a rebase sequence is in progress, the status buffer features a section that lists the commits that have already been applied as well as the commits that still have to be applied.
The commits are split in two halves. When rebase stops at a commit,
either because the user has to deal with a conflict or because s/he
explicitly requested that rebase stops at that commit, then point is
placed on the commit that separates the two groups, i.e., on HEAD
.
The commits above it have not been applied yet, while the HEAD
and the
commits below it have already been applied. In between these two
groups of applied and yet-to-be applied commits, there sometimes is a
commit which has been dropped.
Each commit is prefixed with a word and these words are additionally shown in different colors to indicate the status of the commits.
The following colors are used:
default
face have
not been applied yet.
HEAD
commit.
HEAD
(e.g., because you haven’t done
anything yet after rebase stopped at the commit, then this commit is
shown in blue, not green). There can only be a green and a blue
commit at the same time, if you create one or more new commits after
rebase stops at a commit.
Of course these colors are subject to the color-theme in use.
The following words are used:
pick
, reword
, edit
, squash
, and fixup
have not
been applied yet. These words have the same meaning here as they do
in the buffer used to edit the rebase sequence. See Editing Rebase Sequences. When the --rebase-merges
option was specified,
reset
, label
, and merge
lines may also be present.
done
and onto
have already been applied.
It is possible for such a commit to be the HEAD
, in which case it
is blue. Otherwise it is grey.
onto
is the commit on top of which all
the other commits are being re-applied. This commit itself did
not have to be re-applied, it is the commit rebase did rewind to
before starting to re-apply other commits.
done
have already been re-applied. This
includes commits that have been re-applied but also new commits
that you have created during the rebase.
To determine whether a commit is related to the stopped-at commit their hashes, trees and patch-ids 1 are being compared. The commit message is not used for this purpose.
Generally speaking commits that are related to the stopped-at commit can have any of the used colors, though not all color/word combinations are possible.
Words used for stopped-at commits are:
void
, then that indicates that
Magit knows for sure that all the changes in that commit have been
applied using several new commits. This commit is no longer
reachable from HEAD
, and it also isn’t one of the commits that
will be applied when resuming the session.
join
, then that indicates that the
rebase sequence stopped at that commit due to a conflict - you now
have to join (merge) the changes with what has already been
applied. In a sense this is the commit rebase stopped at, but
while its effect is already in the index and in the worktree (with
conflict markers), the commit itself has not actually been applied
yet (it isn’t the HEAD
). So it is shown in yellow, like the other
commits that still have to be applied.
stop
or a blue or green same
, then
that indicates that rebase stopped at this commit, that it is
still applied or has been applied again, and that at least its
patch-id is unchanged.
stop
, then that indicates that
rebase stopped at that commit because you requested that
earlier, and its patch-id is unchanged. It might even still be
the exact same commit.
same
, then that
indicates that while its tree or hash changed, its patch-id did
not. If it is blue, then it is the HEAD
commit (as always for
blue). When it is green, then it no longer is HEAD
because
other commit have been created since (but before continuing the
rebase).
goal
, a yellow same,
or work
, then
that indicates that rebase applied that commit but that you then
reset HEAD
to an earlier commit (likely to split it up into
multiple commits), and that there are some uncommitted changes
remaining which likely (but not necessarily) originate from that
commit.
goal
, then that indicates that it
is still possible to create a new commit with the exact same
tree (the "goal") without manually editing any files, by
committing the index, or by staging all changes and then
committing that. This is the case when the original tree still
exists in the index or worktree in untainted form.
same
, then that
indicates that it is no longer possible to create a commit with
the exact same tree, but that it is still possible to create a
commit with the same patch-id. This would be the case if you
created a new commit with other changes, but the changes from
the original commit still exist in the index or working tree in
untainted form.
work
, then that indicates that
you reset HEAD
to an earlier commit, and that there are some
staged and/or unstaged changes (likely, but not necessarily)
originating from that commit. However it is no longer possible
to create a new commit with the same tree or at least the same
patch-id because you have already made other changes.
poof
or gone
, then that indicates
that rebase applied that commit but that you then reset HEAD
to an
earlier commit (likely to split it up into multiple commits), and
that there are no uncommitted changes.
poof
, then that indicates that it
is no longer reachable from HEAD
, but that it has been replaced
with one or more commits, which together have the exact same
effect.
gone
, then that indicates that it
is no longer reachable from HEAD
and that we also cannot
determine whether its changes are still in effect in one or more
new commits. They might be, but if so, then there must also be
other changes which makes it impossible to know for sure.
Do not worry if you do not fully understand the above. That’s okay, you will acquire a good enough understanding through practice.
For other sequence operations such as cherry-picking, a similar section is displayed, but they lack some of the features described above, due to limitations in the git commands used to implement them. Most importantly these sequences only support "picking" a commit but not other actions such as "rewording", and they do not keep track of the commits which have already been applied.
The patch-id is a hash of the changes introduced by a commit. It differs from the hash of the commit itself, which is a hash of the result of applying that change (i.e., the resulting trees and blobs) as well as author and committer information, the commit message, and the hashes of the parents of the commit. The patch-id hash on the other hand is created only from the added and removed lines, even line numbers and whitespace changes are ignored when calculating this hash. The patch-ids of two commits can be used to answer the question "Do these commits make the same change?".
