- **PR Description**
As a followup to #2533, reduce the memory consumption some more by
optimizing the storage of the pipe sets used for the commit graph.
Some coarse measurements (taken by opening the respective repo, typing
`4 >`, and waiting for all commits to be loaded, and then reading the
Memory column in Activity Monitor):
| | master | this PR |
| ------------- | ------- | ------- |
| git | 2.5 GB | 1.0 GB |
| our work repo | 2.3 GB | 1.3 GB |
| linux kernel | 94.8 GB | 38.0 GB |
It's still not really usable for the linux kernel, but for all other
repos that I come across in my daily use of lazygit, it works quite well
now.
Hopefully, graphs will never get wider than 32768 characters. (They would get
kind of hard to navigate if they did...)
This reduces the size of the Pipe struct from 48 to 32 bytes, which makes a
significant difference when there are many millions of instances.
This saves some memory at the cost of a slight performance increase (I suppose
reallocting the slice when adding new Pipes is slightly more expensive now).
Performance of the BenchmarkRenderCommitGraph benchmark is 130μs before, 175μs
after. I'm guessing this is still acceptable.
Change the base type of some of our enums from int to uint8, and reorder fields
for better packing. This reduces the size of models.Commit from 152 to 132 bytes
on my machine.
This doesn't improve overall memory usage significantly, but why not save a
little bit of memory if it's easy.
We need to pass %P instead of %p in the format string of the git log command, so
that the parent hashes have the full length and can be shared with the real
hashes.
This in itself is not an improvement, because hashes are unique (they are shared
between real commits and rebase todos, but there are so few of those that it
doesn't matter). However, it becomes an improvement once we also store parent
hashes in the same pool; but the real motivation for this change is to also
reuse the hash pointers in Pipe objects later in the branch. This will be a big
win because in a merge-heavy git repo there are many more Pipe instances than
commits.
The "// merge commit" comment was plain wrong, this is any commit that has a
parent, merge or not. The "else if" condition was unnecessary, a plain "else"
would have been enough. But the code in the two blocks was almost identical, so
extract the one thing that was different and unify it.
And while we're at it, use IsFirstCommit() instead of counting parents.

This makes it easier to copy diff hunks and paste them into code. We
only strip the prefixes if the copied lines are either all '+' or all
'-' (possibly including context lines), otherwise we keep them. We also
keep them when parts of a hunk header is included in the selection; this
is useful for copying a diff hunk and pasting it into a github comment,
for example.
A not-quite-correct edge case is when you select the '--- a/file.txt'
line of a diff header on its own; in this case we copy it as '--
a/file.txt' (same for the '+++' line). This is probably uncommon enough
that it's not worth fixing (it's not trivial to fix because we don't
know that we're in a header).
Fixes#3859.
Fixes#4511.

In the commits list of an interactive rebase, the gap between the rebase
todo column and the author column was two instead of one. Remove the
extra space to make this gap the same as for all other columns.
This is very old; I can only guess that this was added at a time where today's
list column handling wasn't in place yet, so the space was needed to separate
columns. This now causes a gap of two spaces between the rebase todo column and
the author column, which I'm sure wasn't intended. Funny that I never noticed.

This is very similar to what we are doing for staging or discarding
hunks in the Files panel (see #4235). Git doesn't allow applying patches
with a zero context size (unless you use the --unidiff-zero option,
which is discouraged).
Fixes#4521.

Fish shell does not support "&&" and "||" operators like
POSIX-compatible shells. Instead, it uses a different syntax structure
based on begin/end and if/else.
This caused existing lazygit nvim-remote integration templates to break
when fish was the user's default shell.
This commit adds explicit fish shell detection using the FISH_VERSION
environment variable, and provides fish-compatible templates that
correctly handle launching Neovim or sending remote commands via $NVIM.
Fixes behavior where edits would not open in a new Neovim tab or line
navigation would fail when $NVIM was set.
Ensures smoother editing experience for users running fish shell
(supported since Nov 2012 with FISH_VERSION).

- **PR Description**
Allow pressing `{`, `}`, `(`, and `)` to change the diff context size
and rename threshold when the main view is focused. This was forgotten
in #4429.
- **PR Description**
Add a new command "Move commits to new branch" (bound to `N` by
default), which is useful if you have just started some new work, you
already made some commits, and then you realize that you forgot to
create a new branch first, accidentally making those commits on main or
whichever other feature branch you happened to be on.
If you made those commits on main, you are prompted for a branch name
for the new branch, and then it creates the new branch right there and
hard-resets main to where it was. If you made them on another feature
branch though, you are first given the choice whether you want to create
the new branch from main, or keep it stacked on that other feature
branch. Then it prompts you for the name and proceeds as above.
Inspired by Magit's
[magit-branch-spinoff](https://magit.vc/manual/magit/Branch-Commands.html#index-b-s)
command.
The conditions under which the command is available are rather
restrictive: the current branch must have an upstream, it must not be
behind its upstream, but it must be ahead of it (otherwise there
wouldn't be any commits to move, and you might as well just create a new
branch normally).
The long story: I want to call this function from RefsHelper; however, I can't
make WorkingTreeHelper a field of RefsHelper because RefsHelper is already a
field in WorkingTreeHelper, so that would be a circular dependency.
The shorter story: there's really little reason to have to instantiate a helper
object in order to call a simple function like this. Long term I would like to
get to a state where a lot more of these helper functions are free-standing, and
you pass in the data they need.
While at it, simplify the implementation of AnyStagedFiles and AnyTrackedFiles
to one-liners.
It's the same, really, except that GetCheckedOutRef() does a check if any
branches exist and returns nil if not. Since we are accessing the returned
branch unconditionally without checking for nil, it seems this check is not
needed here. (The functions we are touching here are called from handlers that
are guarded with itemSelected or singleItemSelected, so we know that at least
one branch exists.)
The goal is to get rid of the dependency to refsHelper.
- **PR Description**
Add a new user config for auto-forwarding branches after fetching; by
default this is set to "onlyMainBranches", but it can be set to
"allBranches" to extend it to feature branches too, or to "none" to
disable it.
This is used both when fetching manually by pressing `f` in the files
panel, and for automatic background fetching.
