-Subject: [PATCH] tests: Remove variable-length lookbehind tests for GRegex
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-PCRE2 10.43 has now introduced support for variable-length lookbehind,
-so these tests now fail if GLib is built against PCRE2 10.43 or higher.
-
-See
-https://github.com/PCRE2Project/pcre2/blob/e8db6fa7137f4c6f66cb87e0a3c9467252ec1ef7/ChangeLog#L94.
-
-Rather than making the tests conditional on the version of PCRE2 in use,
-just remove them. They are mostly testing the PCRE2 code rather than
-any code in GLib, so don’t have much value.
-
-This should fix CI runs on msys2-mingw32, which updated to PCRE2 10.43 2
-days ago.
