There's no reason not to allow these.
Technically we could enable a few more, but I chose not to because some might be
surprising or confusing in filtering mode. For example, creating a fixup commit
would work (shift-F), but the newly created commit might not show up if it
doesn't match the filter. Similarly, pressing `f` to fixup a commit into its
parent would work, but that parent commit might not be visible, so users might
expect to be fixing up into the next visible commit.
This is not a behavior change, we already include these in the menu, but that's
because of a bug that we will fix in the next commit.
I find it useful to see these commands, especially for rarely-used custom
commands that you don't want to waste a keybinding on.
When filtering for a file path we use the --follow option for "git log", so it
will follow renames of the file, which is great. However, if you then selected
one of the commits before a rename, you didn't see a diff, because we would pass
the original filter path to the "git show" call.
To fix this, call git log with the --name-status option when filtering by path,
so that each commit reports which file paths are touched in this commit;
remember these in the commit object, so that we can pass them to the "git show"
call later.
Be careful not to store too many such paths unnecessarily. When filtering by
folder rather than file, all these paths will necessarily be inside the original
filter path, so detect this and don't store them in this case.
There is some unfortunate code duplication between loading commits and loading
reflog commits, which I am too lazy to clean up right now.
I don't know why this function argument was added, but I don't like unnecessary
indirections, so I'm removing it as SubCommitsHelper has access to everything it
needs to do it itself.
Recycle reflog commits only for the non-filtered ones.
If we're not filtering, FilteredReflogCommits and ReflogCommits are the same. If
we then enter filtering and get reflog entries again, and pass a
lastReflogCommit, we'd recycle the previous FilteredReflogCommits, which are
unfiltered, so that's no good. Work around this by simply never using the
recycle mechanism when getting the filtered reflog commits.
We could do better by remembering what the last filter path or author was, and
only suppressing the recycling when it changed; but that's more complexity than
I want to add, so hopefully this is good enough.
Using the filtered one is probably not a good idea. It didn't do much harm
because the split of ReflogCommits and FilteredReflogCommits doesn't really work
right now (FilteredReflogCommits is always the same as ReflogCommits, even in
filtering mode), but we'll fix this in the next commit.
I can only guess what happened here: in aa750c0819, this code to manually load
the reflog commits was added, to make sorting branches by recency work when the
reflog is filtered by path. At that time we didn't have separate ReflogCommits
and FilteredReflogCommits models yet. Then, FilteredReflogCommits was introduced
(in 8822c409e2), probably for the very purpose of being able to get rid of this
again; but then it was forgotton to actually get rid of it.
The funny thing is that the introduction of FilteredReflogCommits happened in
the very next commit, 15 minutes later.
Since filtering switches to half-screen mode in the local commits panel, most
people probably didn't notice, but we do also filter those other views. So when
leaving half-screen mode (but not filtering), you could switch to sub-commits or
stashes, and those would show the filtered view only after the next refresh
(e.g. after a background fetch). It's worse when leaving filtering, because this
goes back to normal screen mode, and you would often see an empty stashes panel
after that (until the next background fetch), which is quite confusing.
I also find it questionable to always switch focus to the commits panel when
entering filtering. If it is initiated from subcommits, reflog, or stashes,
maybe we want to stay there. I'm not changing this now since I'm unsure how much
people rely on the current behavior.
When exiting filtering mode while the focus is not in the local commits panel,
the call to HandleFocus would render the selection in the commits panel as if
the panel had the focus.
The call to HandleFocus was introduced recently in 4981419ba9 in an attempt to
rerender the main view correctly, but it should only have been called when local
commits is the focused context. But instead, we can use PostRefreshUpdate, which
handles this distinction.
Previously a click was detected as a double-click whenever the click was on the
already selected line, regardless of how long ago the last click was (or even
when it wasn't selected by clicking at all). Now that gocui supports proper
double-click detection, we can do better.
When entering filtering we would only call FocusLine, which takes care of
highlighting the selected line in the commits list, but not of re-rendering the
main view. HandleFocus does that.
When exiting filtering, the HandleFocus call was missing entirely.
The tests needed to be reworked a little bit to make this testable.
At the same time, we change the defaults for both of them to "date" (they were
"recency" and "alphabetical", respectively, before). This is the reason we need
to touch so many integration tests. For some of them I decided to adapt the test
assertions to the changed sort order; for others, I added a SetupConfig step to
set the order back to "recency" so that I don't have to change what the test
does (e.g. how many SelectNextItem() calls are needed to get to a certain
branch).
When toggling the value in the UI we simply overwrite the value in UserConfig;
this would be bad if there was ever a chance that we want to write the user
config back to disk, but it is very unlikely that we can do that, because
currently we have no way to tell which parts of the config come from the global
config file and which ones come from a repo-local one.
The code was copied from StagingController in 0496e3af50, and I did add the new
text in that commit, I just forgot to adapt the code to actually use it.
We only want to do this when the function is called from the remote branches
panel. It can also be called with a selection of local branches in order to
delete their remote branches, but in this case the selection shouldn't be
collapsed because the local branches stay around.
We had code already that was supposed to do this, but it didn't work. It should
have used SetSelection() instead of SetSelectedLineIdx(); the latter doesn't
actually cancel a range selection.
Introduce a new function specifically for collapsing the range after deleting
multiple items, so that clients don't need two calls (we'll add a bunch more in
this branch).
While it's true that the behavior is a little different from the staging panel,
where the staged lines are actually removed from the view and in many cases the
selection stays more or less in the same place, it is still very useful to move
to the next stageable thing in the custom patch building view too.
This improves the experience when selecting a hunk generously with the mouse, by
dragging over it including some context lines above and below. Previously we
would consider the "moving end" of the selection range for whether things need
to be added or removed, but this doesn't make sense if it's a context line. Now
we consider the first actual change line that is included in the range.
CheckMergeOrRebase calls Refresh already. However, it does an async refresh by
default, so we must turn this into a sync refresh so that moving the selection
down by one works even for the very first commit in history. Also, we must add
an explicit call to FocusLine so that the view selection is in sync with the
model selection; previously this was taken care of by the PostRefreshUpdate call
that happens as part of a refresh.
Keep the same commit selected, by moving the selection down by the number of
cherry-picked commits. We also do this when reverting commits, and it is
possible now that we use a sync waiting status.
We also need to turn the refresh that happens as part of CheckMergeOrRebase into
a sync one, so that the commits list is up to date and the new selection isn't
clamped.
For the case of creating a new branch by moving commits to it, we were using the
current (old) branch name in the stash name; change this to use the new name
instead.
