Here is the list of some established lock ordering.
|
|
|
|
In this list, A -> B means that you can have A.Lock() then B.Lock(), not the opposite.
|
|
|
|
jetStream -> jsAccount -> Server -> client -> Account
|
|
|
|
jetStream -> jsAccount -> stream -> consumer
|
|
|
|
A lock to protect jetstream account's usage has been introduced: jsAccount.usageMu.
|
|
This lock is independent and can be invoked under any other lock: jsAccount -> jsa.usageMu, stream -> jsa.usageMu, etc...
|
|
|
|
A lock to protect the account's leafnodes list was also introduced to
|
|
allow that lock to be held and the acquire a client lock which is not
|
|
possible with the normal account lock.
