[Feature]: add synchronization for Conn to make it concurrency-safe #557
Description
Description of new feature
For the time being, most of gnet.Conn's methods are not concurrency-safe, which may result in some inconvenience and limitations, or performance issues like #423. Hence, I'd like to investigate the possibility of introducing the synchronization mechanism for gnet.Conn.
Scenarios for new feature
Any scenarios where gnet.Conn is required to be used in goroutines outside the event loop will benefit from this new feature.
Breaking changes or not?
No
Code snippets (optional)
What I have in mind at the moment is something like this:
type Options struct {
...
// Locker will be utilized as a synchronization to ensure the concurrent safety of the gnet.Conn.
Locker sync.Locker
}
func WithLocker(locker sync.Locker) Option {
return func(opts *Options) {
opts.Locker = locker
}
}This is just an initial idea, it's not necessarily the final implementation.
Alternatives for new feature
We can also do this internally without exposing any new APIs, which might be more straightforward but less flexiable.
Additional context (optional)
None.
