[SOLVED] jemalloc 5.3.0

villeph · 09-10-2022, 10:46 AM

Hello. I tried asking this over the email but didn't hear back.

Is there a reason we're still on jemalloc 5.2.1 (a version from 2019) ? The version 5.3.0 has been out for a few months now.

I'm not sure if some stock Slackware packages need to be recompiled if it gets upgraded. I compiled 5.3.0 with the official SlackBuild and haven't had any issues so far... although the programs that use the library are also compiled by me.

Release info:
https://github.com/jemalloc/jemalloc/releases/tag/5.3.0

Code:

This release contains many speed and space optimizations, from micro
optimizations on common paths to rework of internal data structures and
locking schemes, and many more too detailed to list below. Multiple percent
of system level metric improvements were measured in tested production
workloads. The release has gone through large-scale production testing.

Afaik jemalloc is only used in Slackware by mariadb.
In the past updating jemalloc version caused problems, mostly when switching from 4.x to 5.x.
I guess it just need to be properly tested before it gets updated, either directly or by being widely adopted by other distros.

archlinux have 5.3.0 since long time , then its possible the issues non exist in recent mariadb releases.

Archlinux , sau bind , is other package using jemalloc.

Got it. I have Python 3.10 apps dependent on jemalloc and also Redis which uses the library so I'll be sticking with the latest version.

I still doubt it'd cause issues if it was updated. I don't use MariaDB but I didn't find any info about it breaking if jemalloc 5.3.0 was used instead of 5.2.1.
