When using TLS with a Redis.conf file the line for TLS reading tls-cert-file redis.crt tls-key-file redis.key is interpreted as one complete directive. I am separating this on two separate lines to improve usability so users do not get the below error.
ubuntu@ip-172-31-29-250:~/redis-6.0-rc1$ ./src/redis-server redis.conf
*** FATAL CONFIG FILE ERROR ***

"Partial Resynchronization" is a special variant of replication success
that we have to tell systemd about if it is managing redis-server via a
Type=Notify service unit.
*** [err]: PSYNC2: total sum of full synchronizations is exactly 4 in tests/integration/psync2.tcl
Expected 5 == 4 (context: type eval line 6 cmd {assert {$sum == 4}} proc ::test)
issue was that sometime the test got an unexpected full sync since it
tried to switch to the replica before it was in sync with it's master.
The callback approach we took is very efficient, the module can do any
filtering of keys without building any list and cloning strings, it can
also read data from the key's value. but if the user tries to re-open
the key, or any other key, this can cause dict re-hashing (dictFind does
that), and that's very bad to do from inside dictScan.
this commit protects the dict from doing any rehashing during scan, but
also warns the user not to attempt any writes or command calls from
within the callback, for fear of unexpected side effects and crashes.
This makes simpler to give people help when posting such kind of errors
in the mailing list or other help forums, because sometimes the
directive looks well spelled, but the version of Redis they are using is
not able to support it.
it seems that running two clients at a time is ok too, resuces action
time from 20 minutes to 10. we'll use this for now, and if one day it
won't be enough we'll have to run just the sensitive tests one by one
separately from the others.
this commit also fixes an issue with the defrag test that appears to be
very rare.
seems that github actions are slow, using just one client to reduce
false positives.
also adding verbose, testing only on latest ubuntu, and building on
older one.
when doing that, i can reduce the test threshold back to something saner
I saw that the new defag test for list was failing in CI recently, so i
reduce it's threshold from 12 to 60.
besides that, i add / improve the latency test for that other two defrag
tests (add a sensitive latency and digest / save checks)
and fix bad usage of debug populate (can't overrides existing keys).
this was the original intention, which creates higher fragmentation.
