From 188e9e28c5287f3f160b5f14e3e551b1c55c7301 Mon Sep 17 00:00:00 2001 From: Ævar Arnfjörð Bjarmason Date: Mon, 12 Apr 2021 19:15:14 +0200 Subject: pickaxe: die when -G and --pickaxe-regex are combined MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the -G and --pickaxe-regex options are combined we simply ignore the --pickaxe-regex option. Let's die instead as suggested by our documentation, since -G is always a regex. When --pickaxe-regex was added in d01d8c6782 (Support for pickaxe matching regular expressions, 2006-03-29) only the -S option existed. Then when -G was added in f506b8e8b5 (git log/diff: add -G that greps in the patch text, 2010-08-23) neither the documentation for --pickaxe-regex was updated accordingly, nor was something like this assertion added. Since 5bc3f0b567 (diffcore-pickaxe doc: document -S and -G properly, 2013-05-31) we've claimed that --pickaxe-regex should only be used with -S, but have silently tolerated combining it with -G, let's die instead.
