Wilfred Hughes 4fdc8eebcd Increase MSRV to 1.59 2023-08-07 20:32:08 +07:00
Wilfred Hughes 892d4fdb58 Ensure size_hint never exceeds graph_limit 
If we have thousands of syntax nodes on both sides, we can end
up attempting to preallocate a very large hashmap.

In #542, a user hit an issue with two JSON files where the LHS had
33,000 syntax nodes and the RHS had 34,000 nodes, so we'd attempt to
preallocate a hashmap of capacity 1,122,000,000. This required
allocating 70,866,960,400 bytes (roughly 66 GiB).

Impose a sensible limit on the hashmap.

Fixes #542

Wilfred Hughes 757c297412 Adjust header style 
Show the hunk count and detected language in a dimmed style. This
information is less important than the diff content itself, so this
change makes the important information more prominent.

Wilfred Hughes b3acf48128 Bump minimum required Rust version to 1.58 
Difftastic is generally conservative about MSRV, and will only
increase the version when there is a compelling reason (e.g. major
performance improvement, important bug fix in a dependendency).

This version increase will enable us to upgrade crossterm to 0.26, which
has better detection of terminal width on Windows.

I've also clarified MSRV details for other dependencies that cannot
currently be upgraded.

Wilfred Hughes 4e9637c861 Check more bytes when detecting encoding 
I've observed PDF files that have sufficiently large headers that they
were detected as text, which wasn't helpful.

Also improve logging to report how many invalid bytes were found.

Wilfred Hughes 7caaaf7fcf Handle nested sliders correctly when preferring the outer delimiter 
Previously we didn't check the state of children, which was an
oversight from the original implementation. As a result, we fixed
nested sliders in fewer situations.

Wilfred Hughes c07e640b24 Remove contiguous penalty 
The contiguous penalty was an attempt to fix the slider problem:

// Old
A B
C D

// New
A B
A B
C D

// Unwanted diff
A +B+
+A+ B
C D

However, it doesn't make sense for Dijkstra, which is stateless. The
best route from vertex X is independent of how we got to vertex X.

This worked by dumb luck: in some circumstances we terminate early
rather than fully executing Dijkstra's algorithm. This cost tweak
improved results on a few test files. However, the post-processing
slider logic is a proper, general solution. This was added much later.

There's no reason to keep the contiguous penalty now. It's confusing,
and makes adding new edge costs with consistent 'X costs more than Y'
behaviours more difficult.

Performance is essentially neutral: a small decrease in
typing_before.ml, a small increase in slow_before.rs.
