TLS: Propagate and handle SSL_new() failures. (#7576) 
The connection API may create an accepted connection object in an error
state, and callers are expected to check it before attempting to use it.

RESTORE ABSTTL skip expired keys - leak (#7511) 2020-07-13 16:40:19 +03:00
Oran Agra 5977a94842
RESTORE ABSTTL won't store expired keys into the db (#7472) 
Similarly to EXPIREAT with TTL in the past, which implicitly deletes the
key and return success, RESTORE should not store key that are already
expired into the db.
When used together with REPLACE it should emit a DEL to keyspace
notification and replication stream.

Liu Zhen 3984dc6539 fix clusters mixing accidentally by gossip 
`clusterStartHandshake` will start hand handshake
and eventually send CLUSTER MEET message, which is strictly prohibited
in the REDIS CLUSTER SPEC.
Only system administrator can initiate CLUSTER MEET message.
Futher, according to the SPEC, rather than IP/PORT pairs, only nodeid
can be trusted.

antirez 00a3bc4359 Cluster: introduce data_received field. 
We want to send pings and pongs at specific intervals, since our packets
also contain information about the configuration of the cluster and are
used for gossip. However since our cluster bus is used in a mixed way
for data (such as Pub/Sub or modules cluster messages) and metadata,
sometimes a very busy channel may delay the reception of pong packets.
So after discussing it in #7216, this commit introduces a new field that
is not exposed in the cluster, is only an internal information about
the last time we received any data from a given node: we use this field
in order to avoid detecting failures, claiming data reception of new
data from the node is a proof of liveness.

antirez 30adc62232 RDB: load files faster avoiding useless free+realloc. 
Reloading of the RDB generated by

    DEBUG POPULATE 5000000
    SAVE

is now 25% faster.

This commit also prepares the ability to have more flexibility when
loading stuff from the RDB, since we no longer use dbAdd() but can
control exactly how things are added in the database.

Oran Agra 28c20b4ef9 rename RN_SetLRUOrLFU -> RM_SetLRU and RN_SetLFU 
- the API name was odd, separated to two apis one for LRU and one for LFU
- the LRU idle time was in 1 second resolution, which might be ok for RDB
  and RESTORE, but i think modules may need higher resolution
- adding tests for LFU and for handling maxmemory policy mismatch
