[debian-mysql] Bug#939863: mariadb-server-10.3: won't start without libjemalloc1 from jessie

[Cory Petkovsek]

Package: mariadb-server-10.3
Version: 1:10.3.17-0+deb10u1

After removing a bunch of "unnecessary" libraries yesterday I
discovered that mariadb would not restart. After many seconds of
failure, the only worthwhile log entry is a vague message that
suggests it would like to have libjemalloc.so.1, but doesn't really
need it.

Turns out mysqld will not start without it installed. But libjemalloc1
doesn't exist in stable. I downloaded and installed
libjemalloc1_3.6.0-3_amd64.deb from Jessie and mysql started right up.

So mariadb-server-10.3 needs to depend on libjemalloc1 which needs to
be put back in stable. Or have it compiled for and depend on
libjemalloc2, which is in stable.
