Subject: Re: [PATCH v2] grep: avoid setting UTF mode when dangerous with PCRE
Date: Thu, 18 Nov 2021 07:49:29 -0500	[thread overview]
Message-ID: <HAQR2R.KZGF0ERBQ2Z72@effective-light.com> (raw)
In-Reply-To: <CAPUEsphbA0Qrnt-MdxyYT2OMrnXnbi0tN5_YNqLypCqDqZyeWg@mail.gmail.com>

If none of the patches that are trying to fix our usage of PCRE2 are 
ACKed.
It would be preferable (from my perspective) to revert only ae39ba431a
(grep/pcre2: fix an edge case concerning ascii patterns and UTF-8 data,
2021-10-15) and disable the feature (for the time being) if PCRE2 is 
selected, like so:

diff --git a/pretty.c b/pretty.c
index 1af5b093ae..a53d008d1e 100644
--- a/pretty.c
+++ b/pretty.c
@@ -452,7 +452,7 @@ static void append_line_with_color(struct strbuf 
*sb, struct grep_opt *opt,
  buf = line;
  eol = buf + linelen;

- if (!opt || !want_color(color) || opt->invert)
+ if (!opt || !want_color(color) || opt->invert || opt->pcre2)
   goto end;

  line_color = opt->colors[GREP_COLOR_SELECTED];
