From: Maxim Kokryashkin via Tarantool-patches <tarantool-patches@dev.tarantool.org> To: tarantool-patches@dev.tarantool.org, skaplun@tarantool.org, sergeyb@tarantool.org Subject: [Tarantool-patches] [PATCH luajit 2/4] memprof: refactor `heap_chunk` data structure Date: Mon, 4 Dec 2023 16:25:00 +0300 [thread overview] Message-ID: <e489cb733033cf51a62f244f45618c47857a57bc.1701696044.git.m.kokryashkin@tarantool.org> (raw) In-Reply-To: <cover.1701696044.git.m.kokryashkin@tarantool.org> The memprof parser used to have the `heap_chunk` data structure using numeric indices for its values, which is hardly readable and maintainable. This patch replaces these numeric indices with corresponding string keys.
