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.
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 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.
It is useful to see if the conflicted commit was a "pick" or an "edit". What's
more, we're about to add support for showing cherry-picks and reverts, and
seeing that a conflicted commit was a revert is important because its diff is
backwards compared to the diff of the conflicting files in the Files panel.
It looks like enums.go was supposed to be file that collects a bunch of enums,
but actually there's only one in there, and since it has methods, it deserves to
be in a file of its own, named after the type.
We used to automatically color branches starting with "feature/", "bugfix/", or
"hotfix/". For those who don't want this, it's a bit non-obvious to turn off,
but it's actually pretty easy to configure manually for those who want this, so
we just remove this default coloring.
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.
The string literal "\uf0868" does *not* create a single rune with the code point
f0868, as was intended; instead, it creates two runes, one with the code point
f086, followed by the character '8'.
I don't know what this condition is supposed to guard against, or whether we
really need it (it was added in 06ca71e955, and the commit message of that
commit only says "fix bug"). But if we do need it, then it seems that `>=` is
more correct than `>`.
