1343432 - Update jemalloc 4 to version 4.5.0

Status: RESOLVED FIXED

(Core :: Memory Allocator, defect)

Description

[Ryan VanderMeulen [:RyanVM]]

https://github.com/jemalloc/jemalloc/releases/tag/4.5.0

* 4.5.0 (February 28, 2017)

  This is the first release to benefit from much broader continuous integration
  testing, thanks to @davidtgoldblatt.  Had we had this testing infrastructure
  in place for prior releases, it would have caught all of the most serious
  regressions fixed by this release.

  New features:
  - Add --disable-thp and the opt.thp to provide opt-out mechanisms for
    transparent huge page integration.  (@jasone)
  - Update zone allocator integration to work with macOS 10.12.  (@glandium)
  - Restructure *CFLAGS configuration, so that CFLAGS behaves typically, and
    EXTRA_CFLAGS provides a way to specify e.g. -Werror during building, but not
    during configuration.  (@jasone, @ronawho)

  Bug fixes:
  - Fix DSS (sbrk(2)-based) allocation.  This regression was first released in
    4.3.0.  (@jasone)
  - Handle race in per size class utilization computation.  This functionality
    was first released in 4.0.0.  (@interwq)
  - Fix lock order reversal during gdump.  (@jasone)
  - Fix-refactor tcache synchronization.  This regression was first released in
    4.0.0.  (@jasone)
  - Fix various JSON-formatted malloc_stats_print() bugs.  This functionality
    was first released in 4.3.0.  (@jasone)
  - Fix huge-aligned allocation.  This regression was first released in 4.4.0.
    (@jasone)
  - When transparent huge page integration is enabled, detect what state pages
    start in according to the kernel's current operating mode, and only convert
    arena chunks to non-huge during purging if that is not their initial state.
    This functionality was first released in 4.4.0.  (@jasone)
  - Fix lg_chunk clamping for the --enable-cache-oblivious --disable-fill case.
    This regression was first released in 4.0.0.  (@jasone, @428desmo)
  - Properly detect sparc64 when building for Linux.  (@glaubitz)

Attachment: update jemalloc 4 to version 4.5.0

I ran a Try push off the rc-4.5.0 branch a few days ago without issue, so I'm not expecting any problems with the final release. But here's a new Try run just in case.

And FWIW, the OSX logalloc-replay bustage is there for jemalloc4 builds in general, not a new issue with 4.5.0.
