When pushing a branch that didn't have an upstream yet, we use the command line
git push --set-upstream origin HEAD:branch-name
The HEAD: part of this is too unspecific; when checking out a different branch
while the push is still running, then git will set the upstream branch on the
newly checked out branch, not the branch that was being pushed. This might be
considered a bug in git; you might expect that it resolves HEAD at the beginning
of the operation, and uses the result at the end.
But we can easily work around this by explicitly supplying the real branch name
instead of HEAD.
We use an interactive shell so that users can use their custom shell aliases in
lazygit's shell prompt, which is convenient; however, this only really works for
shells like bash or zsh. We know it doesn't work for fish or nushell (because
these use different names for the $? variable); so use an interactive shell only
if the user's shell is either bash or zsh.
There are two ways to jump to the editor on a specific line: pressing `e` in the
staging or patch building panels, or clicking on a hyperlink in a delta diff. In
both cases, this works perfectly in the unstaged changes view, but in other
views (either staged changes, or an older commit) it can often jump to the wrong
line; this happens when there are further changes to the file being viewed in
later commits or in unstaged changes.
This commit fixes this so that you end up on the right line in these cases.
In 5a3049485c we changed the execution of shell commands to use an interactive
shell (-i), because this allows users to use aliases or shell functions, which
is a nice convenience.
Since then, however, many users have reported problems with lazygit not coming
back to the foreground after executing a shell command. Some users report that
appending "; exit" to the end of the command line solves this. I don't really
understand what the cause of this problem was, or why appending "; exit" solves
it, but if it helps, let's do it.
For non-merge commits we change "pick" to "drop" when we delete them. We do this
so that we can use the same code for dropping a commit no matter whether we are
in an interactive rebase or not. (If we aren't, we could just as well delete the
pick line from the todo list instead of setting it to "drop", but if we are, it
is better to keep the line around so that the user can change it back to "pick"
if they change their mind.)
However, merge commits can't be changed to "drop", so we have to delete them
from the todo file. We add a new daemon instruction that does this.
We still don't allow deleting a merge commit from within an interactive rebase.
The reason is that we don't show the "label" and "reset" todos in lazygit, so
deleting a merge commit would leave the commits from the branch that is being
merged in the list as "pick" commits, with no indication that they are going to
be dropped because they are on a different branch, and the merge commit that
would have brought them in is gone. This could be very confusing.
One of the comments we are deleting here said:
// Comparing just the hash is not enough; we need to compare both the
// action and the hash, as the hash could appear multiple times (e.g. in a
// pick and later in a merge).
I don't remember what I was thinking when I wrote this code, but it's nonsense
of course. Maybe I was thinking that the hash that appears in a "merge" todo
would be the hash of the commit that is being merged in (which would then
actually appear in an earlier pick), but it isn't, it's the hash of the merge
commit itself (so that the rebase can reuse its commit message). Which means
that hashes are unique, no need to compare the action.
When enabled, it adds "+n -m" after each file in the Files panel to show how
many lines were added and deleted, as with `git diff --numstat` on the command
line.
It is needed by both call sites of this function. This has the added benefit
that the argument doesn't unnecessarily show up in the status view when diffing
mode is on.
We will need this because under some conditions we are going to use this
function to edit a range of commits, and we can't set merge commits to "edit".
This corresponds to the code in startInteractiveRebaseWithEdit which has similar
logic.
It is a bit unfortunate that we will have these two different ways of setting
todos to edit: startInteractiveRebaseWithEdit does it after stopping in the
rebase, in the Then function of its refresh, but InteractiveRebase does it in
the daemon with a ChangeTodoActionsInstruction. It still makes sense though,
given how InteractiveRebase works.
This not only affects "edit", but also "drop", "fixup", and "squash".
Previously, when trying to use these for a range selection that includes a merge
commit, they would fail with the cryptic error message "Some todos not found in
git-rebase-todo"; now they simply exclude the merge commit. I'm not sure if one
is better or worse than the other, and we should probably simply disable the
commands when a merge commit is selected, but that's out of scope in this PR.
We allow deleting remote branches (or local and remote branches) only if *all*
selected branches have one.
We show the a warning about force-deleting as soon as at least one of the
selected branches is not fully merged.
The added test only tests a few of the most interesting cases; I didn't try to
cover the whole space of possible combinations, that would have been too much.
Currently we try to delete a branch normally, and if git returns an error and
its output contains the text "branch -D", then we prompt the user to force
delete, and try again using -D. Besides just being ugly, this has the
disadvantage that git's logic to decide whether a branch is merged is not very
good; it only considers a branch merged if it is either reachable from the
current head, or from its own upstream. In many cases I want to delete a branch
that has been merged to master, but I don't have master checked out, so the
current branch is really irrelevant, and it should rather (or in addition) check
whether the branch is reachable from one of the main branches. The problem is
that git doesn't know what those are.
But lazygit does, so make the check on our side, prompt the user if necessary,
and always use -D. This is both cleaner, and works better.

In practice, using path seems to work too, since Windows seems to be capable of
dealing with a path like C:/x/y instead of C:\x\y; but it's cleaner to do this
properly.
Also, use the user's shell (from the SHELL env variable) instead of bash. Both
of these together allow users to use their shell aliases or shell functions in
the interactive command prompt.
This change reduces the number of calls during application startup to
one, calling GetRepoPaths() earlier than previously and plumbing the
repoPaths struct around to achieve this end.
- Introduced a new optional user config command, allBranchesLogCmds
- When pressing 'a' in the Status view, cycle between non-empty, non-identical log commands
- There will always be at least one command to run, since allBranhesLogCmd has a default
- Update documentation & write an integration test
- Update translation string
The current behaviour when creating a new branch off of a remote branch
is to always track the branch it was created from.
For example, if a branch 'my_branch' is created off of the remote branch
'fix_crash_13', then 'my_branch' will be tracking the remote
'fix_crash_13' branch.
It is common practice to have both the local and remote branches named
the same when the local is tracking the remote one. Therefore, it is
reasonable to expect that 'my_branch' should not track the remote
'fix_crash_13' branch.
The new behaviour when creating a new branch off of a remote branch is
to track the branch it was created from only if the branch names match.
If the branch names DO NOT match then the newly created branch will not
track the remote branch it was created from.
For example, if a user creates a new branch 'fix_crash_13' off of the
remote branch 'fix_crash_13', then the local 'fix_crash_13' branch will
track the remote 'fix_crash_13' branch.
However, if the user creates a new branch called 'other_branch_name' off
of the remote branch 'fix_crash_13', then the local 'other_branch_name'
branch will NOT track the remote 'fix_crash_13' branch.
Several custom patch commands on parts of an added file would fail with the
confusing error message "error: new file XXX depends on old contents". These
were dropping the custom patch from the original commit, moving the patch to a
new commit, moving it to a later commit, or moving it to the index.
We fix this by converting the patch header from an added file to a diff against
an empty file. We do this not just for the purpose of applying the patch, but
also for rendering it and copying it to the clip board. I'm not sure it matters
much in these cases, but it does feel more correct for a filtered patch to be
presented this way.
We're going to add another argument in the next commit, and that's getting a bit
much, especially when most of the arguments are bool and you only see true and
false at the call sites without knowing what they mean.
Unfortunately it isn't possible to delete them. This would often be useful, but
our todo rewriting mechanisms rely on being able to find todos by some
identifier (hash for pick, ref for update-ref), and exec todos don't have a
unique identifier.
