We are seeing the timestamp comparison fail in an unexpected way, e.g.
https://zed-dev.sentry.io/issues/7293482758/events/c7f7eab3f8f2463f879d4889a80d623e,
where it seems like `text::Anchor::is_max` should be returning true but
it apparently isn't. Add some more information when this panic happens
to understand what's going on.

Reduces memory usage of `InsertionSlice` from 32 to 24 bytes, `Fragment`
from 120 to 96 bytes by narrowing offsets that are relative to
individual insertion operations from `usize` to `u32`. These offsets are
bounded by the size of a single insertion, not the total buffer size, so
`u32` is sufficient.
To prevent any single insertion from exceeding `u32::MAX` bytes, both
`Buffer::new_normalized` and `apply_local_edit`/`apply_remote_edit` now
split large text insertions into multiple fragments via
`push_fragments_for_insertion`.

Helps #38927
- In the common case, each fragment has at most one deletion, so we can
skip the heap allocation
- SmallVec is smaller than an empty HashSet
- Makes cloning cheaper
- From my analysis of the code it's not possible to have duplicate ticks
(I may be wrong tho)

This shrinks the size of `text::Anchor` from 32 bytes to 24 and
`multi_buffer::Anchor` from 72 bytes to 56
Release Notes:
- Improved the memory usage of Zed a bit
- Ensure that both sides are passed the appropriate companion data to
preserve spacers when syncing
- Remove companion handling in codepaths related to range folding, since
this isn't supported in the side-by-side diff
- Move handling of buffer folding into the block map
- Rework `set_companion` to handle both `DisplayMap`s at once
- DRY some code around block map syncing in the `DisplayMap`
TODO:
- [x] diagnose and fix issue that causes balancing blocks not to render
properly when they are adjacent to spacers (e.g. merge conflict buttons)
- [x] clear balancing blocks when clearing companion
- [x] additional tests: interaction between spacers and balancing
blocks, resizing
Release Notes:

When the version is the same we used to still seek through the
underlying fragment sumtree despite having nothing to return. This has a
lot of unnecessary overhead.

The side-by-side diff heavily relies on a primitive from `buffer_diff`
that converts a point on one side of the diff to a range of points on
the other side. The way this primitive is set up on main is pretty
naive--every time we call `points_to_base_text_points` (or
`base_text_points_to_points`), we need to iterate over all hunks in the
diff. That's particularly bad for the case of constructing a new
side-by-side diff starting from a multibuffer, because we call those
APIs once per excerpt, and the number of excerpts is ~equal to the
number of hunks.
This PR changes the point translation APIs exposed by `buffer_diff` to
make it easier to use them efficiently in `editor`. The new shape is a
pair of functions that return a patch that can be used to translate from
the main buffer to the base text or vice versa. When syncing edits
through the block map that touch several excerpts for the same buffer,
we can reuse this patch for excerpts after the first--so when building a
new side-by-side diff, we'll iterate over each hunk just once.
The shape of the new APIs also sets us up to scale down to cases like
editing on the right-hand side of the diff: we can pass in a point range
and give them permission to return an approximate patch that's only
guaranteed to give the correct results when used with points in that
range. For edits that only affect one excerpt, and given how the project
diff is set up, that should allow us to skip iterating over most of the
hunks in a buffer.

The logic in `anchor_at_offset` and `to_offset` seems inverted when
checking character boundaries. `assert_char_boundary` returns `true`
when the offset IS valid, but the code was adjusting offsets when the
function returned `true` (valid) instead of `false` (invalid).
Release Notes:

This PR reworks the (still feature-gated) side-by-side diff view to use
a different approach to representing the multibuffers on the left- and
right-hand sides.
Previously, these two multibuffers used identical sets of buffers and
excerpts, and were made to behave differently by adding a new knob to
the multibuffer controlling how diffs are displayed. Specifically, the
left-hand side multibuffer would filter out the added range of each hunk
from the excerpts using a new `FilteredInsertedHunk` diff transform, and
the right-hand side would simply not show the deleted sides of expanded
hunks. This approach has some problems:
- Line numbers, and actions that navigate by line number, behaved
incorrectly for the left-hand side.
- Syntax highlighting and other features that use the buffer syntax tree
also behaved incorrectly for the left-hand side.
In this PR, we've switched to using independent buffers to build the
left-hand side. These buffers are constructed using the base texts for
the corresponding diffs, and their lifecycle is managed by `BufferDiff`.
The red "deleted" regions on the left-hand side are represented by
`BufferContent` diff transforms, not `DeletedHunk` transforms. This
means each excerpt on the left represents a contiguous slice of a single
buffer, which fixes the above issues by construction.
The tradeoff with this new approach is that we now have to manually
synchronize excerpt ranges from the right side to the left, which we do
using `BufferDiffSnapshot::row_to_base_text_row`.

Currently we have a single cache for this data shared between all
snapshots which is incorrect, as we might update the cache to a new
version while having old snapshots around which then may try to access
new data with old offsets/rows.

These appear in a lot of stacktraces (especially on windows) despite
them being plain forwarding calls.

This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
As discussed in the first responders meeting. We have collected a lot of
backtraces from these, but it's not quite clear yet what causes this.
Removing these should ideally make things a bit more stable even if we
may run into panics later one when the faulty anchor is used still.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
We only use it a handful of times and the default amount of threads
(logical cpu core number) its spawns is overkill for this. This also
gives the threads names oppose to being labeled `<unknown>`

Closes https://github.com/zed-industries/zed/issues/38453
Current `Buffer` API only allows getting buffer text with `\n` line
breaks — even if the `\r\n` was used in the original file's text.
This it not correct in certain cases like LSP formatting, where language
servers need to have original document context for e.g. formatting
purposes.
Added new `Buffer` API, replaced all buffer LSP registration places with
the new one and added more tests.
Release Notes:
- Fixed ESLint linebreak-style errors by preserving line endings in LSP
communication

Closes#5294
This PR adds a line ending indicator to the status bar, hidden by
default as discussed in
https://github.com/zed-industries/zed/issues/5294.
### Changes
- 8b063a22d8700bed9c93989b9e0f6a064b2e86cf add the indicator and
`status_bar.line_endings_button` setting.
- ~~9926237b709dd4e25ce58d558fd385d63b405f3b changes
`status_bar.line_endings_button` from a boolean to an enum:~~
<details> <summary> show details </summary>
- `always` Always show line endings indicator.
- `non_native` Indicate when line endings do not match the current
platform.
- `lf_only` Indicate when using unix-style (LF) line endings only.
- `crlf_only` Indicate when using windows-style (CRLF) line endings
only.
- `never` Do not show line endings indicator.
I know this many options might be overdoing it, but I was torn between
the pleasant default of `non_native` and the simplicity of `lf_only` /
`crlf_only`.
My thinking was if one is developing on a project which exclusively uses
one line-ending style or the other, it would be nice to be able to
configure no-indicator-in-the-happy-case behavior regardless of the
platform zed is running on. But I'm not really familiar with any
projects that use exclusively CRLF line endings in practice. Is this a
scenario worth supporting or just something I dreamed up?
</details>
- 01174191e4cf337069e7a31b0f0432ae94c52515 rename the action context for
`line ending: Toggle` -> `line ending selector: Toggle`.
When running the action in the command palette with the old name I felt
surprised to be greeted with an additional menu, with the new name it
feels more predictable (plus now it matches
`language_selector::Toggle`!)
### Future work
Hidden status bar items still get padding, creating inconsistent spacing
(and it kind of stands out where I placed the line-endings button):
<img alt="the gap after the indicator is larger than for other buttons"
src="https://github.com/user-attachments/assets/24a346d4-3ff6-4f7f-bd87-64d453c2441a"
/>
I started a new follow-up PR to address that:
https://github.com/zed-industries/zed/pull/39992
Release Notes:
- Added line ending indicator to the status bar (disabled by default;
enabled by setting `status_bar.line_endings_button` to `true`)
Reduces peak stack usage in these functions and should generally be a
bit performant.

We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.
Release Notes:
- N/A
Closes#5355
Release Notes:
- Fixed rendering glitches with files with more than 16 million lines
(that occured due to floating number rounding errors).
