Subject: [PATCH] clear_pattern_list(): clear embedded hashmaps
Date: Fri, 14 Aug 2020 07:10:49 -0400	[thread overview]
Message-ID: <20200814111049.GA4101811@coredump.intra.peff.net> (raw)

Commit 96cc8ab531 (sparse-checkout: use hashmaps for cone patterns,
2019-11-21) added some auxiliary hashmaps to the pattern_list struct,
but they're leaked when clear_pattern_list() is called.

Signed-off-by: Jeff King <peff@peff.net>

I have no idea how often this leak triggers in practice. I just noticed
it while poking at LSan output (which we remain depressingly far
from getting a clean run on).
