Update ruby-diff-lcs to 1.4.4.
## 1.4.4 / 2020-07-01
- Fixed an issue reported by Jun Aruga in the Diff::LCS::Ldiff binary text
detection. [#44][]
- Fixed a theoretical issue reported by Jun Aruga in Diff::LCS::Hunk to raise
a more useful exception. [#43][]
- Added documentation that should address custom object issues as reported in
[#35][].
- Fixed more diff errors, in part reported in [#65][].
- The use of `Numeric#abs` is incorrect in `Diff::LCS::Block#diff_size`.
The diff size _must_ be accurate for correct change placement.
- When selecting @max_diff_size in Diff::LCS::Hunk, choose it based on
`block.diff_size.abs`.
- Made a number of changes that will, unfortunately, increase allocations
at the cost of being safe with frozen strings.
- Add some knowledge that when `Diff::LCS::Hunk#diff` is called, that we
are processing the _last_ hunk, so some changes will be made to how the
output is generated.
- `old`, `ed`, and `reverse_ed` formats have no differences.
- `unified` format will report `\ No newline at end of file` given the
correct conditions, at most once. Unified range reporting also
differs for the last hunk such that the `length` of the range is
reduced by one.
- `context` format will report `\No newline at end of file` given the
correct conditions, up to once per "file". Context range reporting also
differs for the last hunk such that the `end` part of the range is
reduced by one to a minimum of one.
- Added a bunch more tests for the cases above, and fixed `hunk_spec.rb` so
that the phrase being compared isn't nonsense French.
- Updated formatting.
- Added a Rake task to assist with manual testing on Ruby 1.8.
## 1.4.3 / 2020-06-29
- Fixed several issues with the 1.4 on Rubies older than 2.0. Some of this was
providing useful shim functions to Hoe 3.x (which dropped these older
Rubies a while ago). Specifically:
- Removed Array#lazy from a method in Diff::LCS::Hunk.
- Changed some unit tests to use old-style Symbol-keyed hashes.
- Changed some unit test helper functions to no longer use keyword
parameters, but only a trailing options hash.
- Made the use of `psych` dependent on `RUBY_VERSION >= 1.9`.
Resolves [#63][].
## 1.4.2 / 2020-06-23
- Camille Drapier fixed a small issue with RuboCop configuration. [#59][]
- Applied another fix (and unit test) to fix an issue for the Chef team.
[#60][], [#61][]
## 1.4.1 / 2020-06-23
- Fix an issue where diff sizes could be negative, and they should be. [#57][],
[#58][]
## 1.4 / 2020-06-23
- Ruby versions lower than 2.4 are soft-deprecated and will not be run as
part of the CI process any longer.
- Akinora MUSHA (knu) added the ability for Diff::LCS::Change objects to be
implicitly treated arrays. Originally provided as pull request [#47][],
but it introduced a number of test failures as documented in [#48][], and
remediation of Diff::LCS itself was introduced in [#49][].
- Resolved [#5][] with some tests comparing output from `system` calls to
`bin/ldiff` with some pre-generated output. Resolved [#6][] with these
tests.
- Resolved a previously undetected `bin/ldiff` issue with `--context` output
not matching `diff --context` output.
- Resolved an issue with later versions of Ruby not working with an `OptParse`
specification of `Numeric`; this has been changed to `Integer`.
- Brandon Fish added truffleruby in [#52][].
- Fixed two missing classes as reported in [#53]
