As discussed in https://github.com/jesseduffield/lazygit/pull/2599, it
makes more sense to have the user specify whether they want verbose
commits from their own git config, rather than lazygit config.
This means that we can remove all the code (including test coverage)
associated with the custom verbose flag, and lazygit will just inherit
the .gitconfig settings automatically.
Save has been deprecated for a while, push is the recommended way to save a
stash. Push has been available since 2.13, so we can use it without problems.
The code in getHydratedRebasingCommits relied on the assumption that the
git-rebase-todo file contains full SHAs. This has only been true from 2.25.2 on,
before that it would contain abbreviated SHAs. Fix this by storing fullCommits
in a slice instead of a map, and using a linear search.
I don't know why we're getting index.lock errors but they're impossile to stop
anyway given that other processes can be calling git commands. So we're retrying
a few times before re-raising. To do this we need to clone the command and the current
implementation for that is best-effort.
I do worry about the maintainability of that but we'll see how it goes.
Also, I thought you'd need to clone the task (if it exists) but now I think not;
as long as you don't call done twice on it you should be fine, and you shouldn't
be done'ing a task as part of running a command: that should happen higher up.
It's not clear what was happening but it seemed like we sometimes weren't
fully writing to our stdout buffer (which is used for the error message)
even though we had returned from cmd.Wait().
Not sure what the cause was but removing an unnecessary goroutine fixed it.
The global counter approach is easy to understand but it's brittle and depends on implicit behaviour that is not very discoverable.
With a global counter, if any goroutine accidentally decrements the counter twice, we'll think lazygit is idle when it's actually busy.
Likewise if a goroutine accidentally increments the counter twice we'll think lazygit is busy when it's actually idle.
With the new approach we have a map of tasks where each task can either be busy or not. We create a new task and add it to the map
when we spawn a worker goroutine (among other things) and we remove it once the task is done.
The task can also be paused and continued for situations where we switch back and forth between running a program and asking for user
input.
In order for this to work with `git push` (and other commands that require credentials) we need to obtain the task from gocui when
we create the worker goroutine, and then pass it along to the commands package to pause/continue the task as required. This is
MUCH more discoverable than the old approach which just decremented and incremented the global counter from within the commands package,
but it's at the cost of expanding some function signatures (arguably a good thing).
Likewise, whenever you want to call WithWaitingStatus or WithLoaderPanel the callback will now have access to the task for pausing/
continuing. We only need to actually make use of this functionality in a couple of places so it's a high price to pay, but I don't
know if I want to introduce a WithWaitingStatusTask and WithLoaderPanelTask function (open to suggestions).
I don't know if this is a hack or not: we run a git command and increment the pending action
count to 1 but at some point the command requests a username or password, so we need to prompt
the user to enter that. At that point we don't want to say that there is a pending action,
so we decrement the action count before prompting the user and then re-increment it again afterward.
Given that we panic when the counter goes below zero, it's important that it's not zero
when we run the git command (should be impossible anyway).
I toyed with a different approach using channels and a long-running goroutine that
handles all commands that request credentials but it feels over-engineered compared to this
commit's approach.
The first line of the diff pane would show branch heads (e.g.
commit dd9100ccc8b69a8b14b21a84e34854b5acfb871a (mybranch, origin/mybranch)
only when a pager is used. The reason is that the default of the --decorate
option to git show is "auto", which means to show the decoration only when
output goes to a tty. Lazygit uses a pty only when a pager is used, so the
decoration wouldn't show when no pager is used.
Since the branch head annotation is useful and we always want to see it, force
it by explicitly passing --decorate.
This solves three problems:
1. When the local main branch is behind its upstream, the merged status of
commits of a feature branch sitting on origin/main was not correct. This can
easily happen when you rebase a branch onto origin/main instead of main, and
don't bother keeping local main up to date.
2. It works when you don't have the main branch locally at all. This could
happen when you check out a colleague's feature branch that goes off of
"develop", but you don't have "develop" locally yourself because you normally
only work on "main".
3. It also works when you work on a main branch itself, e.g. by committing to it
directly, or by merging a branch locally. These local commits on a main
branch would previously be shown in green instead of red; this broke with
910a61dc46.
When stopping in a rebase because of a conflict, it is nice to see the commit
that git is trying to apply. Create a fake todo entry labelled "conflict" for
this, and show the "<-- YOU ARE HERE ---" string for that one (in red) instead
of for the real current head.
Missed a spot a couple PR's ago. We had an integration test which caught this but which was skipped due
to index.lock file issues. The test was also broken for other reasons due to it not having been running
for a while, so I've fixed that up too.
By constructing an arg vector manually, we no longer need to quote arguments
Mandate that args must be passed when building a command
Now you need to provide an args array when building a command.
There are a handful of places where we need to deal with a string,
such as with user-defined custom commands, and for those we now require
that at the callsite they use str.ToArgv to do that. I don't want
to provide a method out of the box for it because I want to discourage its
use.
For some reason we were invoking a command through a shell when amending a
commit, and I don't believe we needed to do that as there was nothing user-
supplied about the command. So I've switched to using a regular command out-
side the shell there
The only exception is when moving a custom patch for an entire commit to an
earlier commit; in this case the source commit becomes empty, but we want to
keep it, mainly for consistency with moving the patch to a later commit, which
behaves the same.
In all other cases where we rebase, it's confusing when empty commits are kept;
the most common example is rebasing a branch onto master, where master already
contains some of the commits of our branch. In this case we simply want to drop
these.
It defaults to {"master", "main"}, but can be set to whatever branch names
are used as base branches, e.g. {"master", "devel", "v1.0-hotfixes"}. It is
used for color-coding the shas in the commit list, i.e. to decide whether
commits are green or yellow.
Previously, when rebasing a branch onto a newer master, all commits from the
previous fork point up to its head were marked red (unpushed), including the
commits that are on master already. While this is technically correct from the
perspective of the current branch's upstream, it's not what most people expect,
intuitively; they want to see where the current branch starts, relative to
master. So all commits of master should be green, and then the commits of the
current branch in red.
When we use the one panel for the entire commit message, its tricky to have a keybinding both for adding a newline and submitting.
By having two panels: one for the summary line and one for the description, we allow for 'enter' to submit the message when done from the summary panel,
and 'enter' to add a newline when done from the description panel. Alt-enter, for those who can use that key combo, also works for submitting the message
from the description panel. For those who can't use that key combo, and don't want to remap the keybinding, they can hit tab to go back to the summary panel
and then 'enter' to submit the message.
We have some awkwardness in that both contexts (i.e. panels) need to appear and disappear in tandem and we don't have a great way of handling that concept,
so we just push both contexts one after the other, and likewise remove both contexts when we escape.
This fixes two problems with the "amend commit with staged changes" command:
1. Amending to a fixup commit didn't work (this would create a commmit with the
title "fixup! fixup! original title" and keep that at the top of the branch)
2. Unrelated fixup commits would be squashed too.
The added integration test verifies that both of these problems are fixed.
Instead of passing a bunch of different options in
PrepareInteractiveRebaseCommandOpts, where it was unclear how they interact if
several are set, have only a single field "instruction" which can be set to one
of various different instructions.
The functionality of replacing the entire todo file with our own is no longer
available; it is only possible to prepend todos to the existing file.
Also, instead of using different env vars for the various rebase operations that
we want to tell the daemon to do, use a single one that contains a json-encoded
struct with all available instructions. This makes the protocol much clearer,
and makes it easier to extend in the future.
At the moment it doesn't make a big difference, because the vast majority of
callers create a list of todos themselves to completely replace what git came up
with. We're changing this in the following commits though, and then it's helpful
to preserve merges.
