2024-04-18Add a hint of `ASCII-8BIT` being `BINARY`Jean Boussier
[Feature #18576] Since outright renaming `ASCII-8BIT` is deemed to backward incompatible, the next best thing would be to only change its `#inspect`, particularly in exception messages.

2023-12-24Fix Regexp#inspect for GC compactionPeter Zhu
rb_reg_desc was not safe for GC compaction because it took in the C string and length but not the backing String object so it get moved during compaction. This commit changes rb_reg_desc to use the string from the Regexp object. The test fails when RGENGC_CHECK_MODE is turned on: TestRegexp#test_inspect_under_gc_compact_stress [test/ruby/test_regexp.rb:474]: <"(?-mix:\\/)|"> expected but was <"/\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00/">.

2023-12-06Copy encoding flags when copying a regex [Bug #20039]Dustin Brown
* :bug: Fixes [Bug #20039](https://bugs.ruby-lang.org/issues/20039) When a Regexp is initialized with another Regexp, we simply copy the properties from the original. However, the flags on the original were not being copied correctly. This caused an issue when the original had multibyte characters and was being compared with an ASCII string. Without the forced encoding flag (`KCODE_FIXED`) transferred on to the new Regexp, the comparison would fail. See the included test for an example.

2023-07-31Reuse Regexp ptr when recompilingPeter Zhu
When matching an incompatible encoding, the Regexp needs to recompile. If `usecnt == 0`, then we can reuse the `ptr` because nothing else is using it. This avoids allocating another `regex_t`. This speeds up matches that switch to incompatible encodings by 15%. Branch: ``` Regex#match? with different encoding 1.431M (± 1.3%) i/s - 7.264M in 5.076153s Regex#match? with same encoding 16.858M (± 1.1%) i/s - 85.347M in 5.063279s ``` Base: ``` Regex#match? with different encoding 1.248M (± 2.0%) i/s - 6.342M in 5.083151s Regex#match? with same encoding 16.377M (± 1.1%) i/s - 82.519M in 5.039504s ``` Script: ``` regex = /foo/ str1 = "日本語" str2 = "English".force_encoding("ASCII-8BIT") Benchmark.ips do |x| x.report("Regex#match? with different encoding") do |times| i = 0 while i < times regex.match?(str1) regex.match?(str2) i += 1 end end x.report("Regex#match? with same encoding") do |times| i = 0 while i < times regex.match?(str1) i += 1 end end end ```

Existing strscan releases rely on this C API. It means that the current Ruby master doesn't work if your Gemfile.lock has strscan unless it's locked to 3.0.7, which is not released yet. To fix it, let's not remove the C API we've exposed to users.

2023-01-30Fix parsing of regexps that toggle extended mode on/off inside regexpJeremy Evans
This was broken in ec3542229b29ec93062e9d90e877ea29d3c19472. That commit didn't handle cases where extended mode was turned on/off inside the regexp. There are two ways to turn extended mode on/off: ``` /(?-x:#y)#z /x =~ '#y' /(?-x)#y(?x)#z /x =~ '#y' ``` These can be nested inside the same regexp: ``` /(?-x:(?x)#x (?-x)#y)#z /x =~ '#y' ``` As you can probably imagine, this makes handling these regexps somewhat complex. Due to the nesting inside portions of regexps, the unassign_nonascii function needs to be recursive. In recursive mode, it needs to track both opening and closing parentheses, similar to how it already tracked opening and closing brackets for character classes. When scanning the regexp and coming to `(?` not followed by `#`, scan for options, and use `x` and `i` to determine whether to turn on or off extended mode. For `:`, indicting only the current regexp section should have the extended mode switched, recurse with the extended mode set or unset. For `)`, indicating the remainder of the regexp (or current regexp portion if already recursing) should turn extended mode on or off, just change the extended mode flag and keep scanning. While testing this, I noticed that `a`, `d`, and `u` are accepted as options, in addition to `i`, `m`, and `x`, but I can't see where those options are documented. I'm not sure whether or not handling `a`, `d`, and `u` as options is a bug. Fixes [Bug #19379] Notes: Merged: https://github.com/ruby/ruby/pull/7192
