Subject: [Tarantool-patches] [PATCH luajit v3 0/4] memprof: group allocations on traces by trace number
Date: Fri, 20 Aug 2021 14:05:41 +0700
Message-ID: <20210820070546.115293-1-m.shishatskiy@tarantool.org> (raw)

New patch series with Sergey's comments in mind.

Changes in v3:
  - Changed comments as per review;
  - Added trace address dump to avoid collisions;
  - Added humanize.describe_location function (see commit
    message);
  - Separated memprof test into subtests to be able to skip
    JIT-related tests on FreeBSD;
  - Adjusted memprof test payload to lock in the behavior 
    (see patch message).

Benchmark update:
