Re: [PATCH v2] grep: avoid setting UTF mode when dangerous with PCRE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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];

This will likely need at least some ACKs.

Apologies for the noise.
