I also converted the error from `InternalError` to `UserError`. So far
I've intented to use `InternalError` only to indicate bugs or corrupt
repos. I'm not sure that's a good idea, and we can revisit it later.
If the path is too long to fit on the screen, this patch makes it so
we elide the first part of it. It goes a bit further and trims it down
to ~70% of the screen, giving some room for the stat. This seems
somewhat similar to what Git does.
`insta` ignores leading indentation (as long as it's consistent within
the snapshot), but when a test case fails and you let `cargo insta`
update it, it's going to use a specific indentation. There were a few
tests that didn't match that indentation, which could lead to
surprising diffs if the tests fail at some point.
This shows that there's too much padding because we pad based on
number of bytes.
I had to reduce the path names for the file names not to get too long
for my file system.
We can still crash on terminals that are less than 4 characters wide
(maybe it doesn't matter if we do because the user can't tell the
crash report from a diffstat in such a terminal?). This patch fixes
the crash.
We would run into a panic due to "attempt to subtract with overflow"
if the path was long. This patch fixes that and adds tests showing the
current behavior when there are long paths and/or large diffs.
When we start writing tree-level conflicts in an existing repo, we
don't want commits that change the format to be non-empty if they
don't change any content. This patch updates `MergeTreeId::eq()` to
consider two resolved trees equal even if only their `MergedTreeId`
variant is different (one is path-level and one is tree-level).
I think I've gone through all places we compare tree ids and checked
that it's safe to compare them this way. One consequence is that
rebasing a commit without changing the parents (typically
auto-rebasing after `jj describe`) will not lead to the tree id
getting upgraded, due to an optimization we have for that case. I
don't think that's serious enough to handle specially; we'll have to
support the old format for existing repos for a while regardless of a
few commits not getting upgraded right away.
The number of failing tests with the config option enabled drop from
108 to 11 with this patch.
We're finally ready to start writing trees using the new format where
we represent conflicts by having multiple trees in the commit instead
of having a single tree with multiple entries at a path. This patch
adds a config option for that. It's not ready to be used yet, so I
haven't updated the release notes or other documentation.
I added only a simple CLI test for testing what happens when the
config is enabled in an existing repo. 108 tests currently fail if we
flip the default.
With the idea that less severe placeholders (like description) could
(and should) explicitly "opt out".
(Both email and name placeholders will be red with this change.)
I made it simply fail on explicit fetch/import, and ignored on implicit import.
Since the error mode is predictable and less likely to occur. I don't think it
makes sense to implement warning propagation just for this.
Closes#1690.
This switches the whole `diff_util` module to working with
`MergedTree`, `Merge<Option<TreeValue>>` etc., so it can support
tree-level conflicts.
Since we want to avoid using `ConflictId`s, I switched the hash we use
for conflicts in `--git` style diffs to use an all-'0' id instead of
using the conflict id.
This patch also extracts format_detailed_signature() function to deduplicate
the "show" template bits.
The added placeholder templates aren't labeled as "empty". If needed, I think
the whole template can be labeled as "empty" (or "empty_commit") just like
"working_copy".
Closes#2112
An alternative name for it would be `arity()`, but `num_sides()`
probably more clearly says that it's not about the number of removes
or the total number of terms.
I think this is less surprising than falling back to the default length.
i64-to-usize conversion can also overflow on 32 bit environment, but I'm not
bothered to handle overflow scenario.
To support tree-level conflicts, we're going to need to update the
working copy from one `MergedTree` to another. We're going need to
store multiple tree ids in the `tree_state` file. This patch gets us
closer to that by getting the diff from `MergedTree`s`, even though we
assume that they are legacy trees for now, so we can write to the
single-tree `tree_state` file.
