  "message": "grep/pcre2: better support invalid UTF-8 haystacks\n\nImprove the support for invalid UTF-8 haystacks given a non-ASCII\nneedle when using the PCREv2 backend.\n\nThis is a more complete fix for a bug I started to fix in\n870eea8166 (grep: do not enter PCRE2_UTF mode on fixed matching,\n2019-07-26), now that PCREv2 has the PCRE2_MATCH_INVALID_UTF mode we\ncan make use of it.\n\nThis fixes the sort of case described in 8a5999838e (grep: stess test\nPCRE v2 on invalid UTF-8 data, 2019-07-26), i.e.:\n\n    - The subject string is non-ASCII (e.g. \"ævar\")\n    - We\u0027re under a is_utf8_locale(), e.g. \"en_US.UTF-8\", not \"C\"\n    - We are using --ignore-case, or we\u0027re a non-fixed pattern\n\nIf those conditions were satisfied and we matched found non-valid\nUTF-8 data PCREv2 might bark on it, in practice this only happened\nunder the JIT backend (turned on by default on most platforms).\n\nUltimately this fixes a \"regression\" in b65abcafc7 (\"grep: use PCRE v2\nfor optimized fixed-string search\", 2019-07-01), I\u0027m putting that in\nscare-quotes because before then we wouldn\u0027t properly support these\ncomplex case-folding, locale etc. cases either, it just broke in\ndifferent ways.\n\nThere was a bug related to this the PCRE2_NO_START_OPTIMIZE flag fixed\nin PCREv2 10.36. It can be worked around by setting the\nPCRE2_NO_START_OPTIMIZE flag. Let\u0027s do that in those cases, and add\ntests for the bug.\n\nSigned-off-by: Ævar Arnfjörð Bjarmason \u003cavarab@gmail.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
