From: Sergey Bronnikov via Tarantool-patches @ 2026-01-22 11:24 UTC (permalink / raw)
To: tarantool-patches, Sergey Kaplun
The patch introduce flags in module "misc" with support status
for sysprof and memprof: `misc.sysprof.enabled` and
`misc.memprof.enabled`. Both flags are boolean and always
available on platforms supported by profilers (Windows is not
supported).
Closes tarantool/tarantool#12215
