We had lots of runs on the Catalyst cloud. I ended up up running up to 10 jobs in parallel isolated VMs to try and get some confidence.
Now, sn-devel isn't the same (much as we tried to emulate it), and there may still be issues, but I will watch it closely.
Thankfully my latest autobuild not only shortens the test time
(trimming down the krb5.kdc test runs), it also includes a fix for a
use-after-free we found with AddressSanitizer, in the schema
replication code. This should fix some of the remaining flaps (such as
the repl_schema one in particular).
Hopefully I wasn't too bold in declaring 'all' the replication bugs
fixed, but I really think Samba 4.5 will be a big improvement in this
space.
