📄 Description

Bumps regex from 1.7.2 to 1.8.4.

Changelog

Sourced from regex's changelog.

1.8.4 (2023-06-05)

This is a patch release that fixes a bug where (?-u:\B) was allowed in Unicode regexes, despite the fact that the current matching engines can report match offsets between the code units of a single UTF-8 encoded codepoint. That in turn means that match offsets that split a codepoint could be reported, which in turn results in panicking when one uses them to slice a &str.

This bug occurred in the transition to regex 1.8 because the underlying syntactical error that prevented this regex from compiling was intentionally removed. That's because (?-u:\B) will be permitted in Unicode regexes in regex 1.9, but the matching engines will guarantee to never report match offsets that split a codepoint. When the underlying syntactical error was removed, no code was added to ensure that (?-u:\B) didn't compile in the regex 1.8 transition release. This release, regex 1.8.4, adds that code such that Regex::new(r"(?-u:\B)") returns to the regex <1.8 behavior of not compiling. (A bytes::Regex can still of course compile it.)

Bug fixes:

[BUG #1006](rust-lang/regex#1006): Fix a bug where (?-u:\B) was allowed in Unicode regexes, and in turn could lead to match offsets that split a codepoint in &str.

1.8.3 (2023-05-25)

This is a patch release that fixes a bug where the regex would report a match at every position even when it shouldn't. This could occur in a very small subset of regexes, usually an alternation of simple literals that have particular properties. (See the issue linked below for a more precise description.)

Bug fixes:

[BUG #999](rust-lang/regex#999): Fix a bug where a match at every position is erroneously reported.

1.8.2 (2023-05-22)

This is a patch release that fixes a bug where regex compilation could panic in debug mode for regexes with large counted repetitions. For example, a{2147483516}{2147483416}{5} resulted in an integer overflow that wrapped in release mode but panicking in debug mode. Despite the unintended wrapping arithmetic in release mode, it didn't cause any other logical bugs since the errant code was for new analysis that wasn't used yet.
