textproc/ruby-diff-lcs: update to 1.4.4
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]
