gnatsd currently uses a global logger. This can cause some problems
(especially around the config-reload work), but global variables are
also just an anti-pattern in general. The current behavior is
particularly surprising because the global logger is configured through
calls to the Server.
This addresses issue #500 by removing the global logger and making it a
field on Server.
Changing from being the number of seconds to a time.Duration.
For backward compatibility, the configuration with the number
of seconds is still accepted but an error message is printed
asking the user to convert to duration.
Resolves#487
We use a hardcoded value of 2 seconds for Write deadline when
writing data to client's socket.
This PR makes that value configurable.
Question is should we push the setting down to the client's object
to avoid indirection such as client.srv.opts.WriteDeadline?
When a server is told to connect to a server (with auto-discovery),
it tries to connect once. There have been a report where that
connection fails, but would probably succeed if tried again (#408).
This new parameter allows to configure the number of times a failed
implicit connect should be tried.
Resolves#408
Previous implementations of the server checked the pending data size
being currently buffered for a client to detect slow consumers,
though this does not apply to latest version of the server so removing
it as a config option to avoid confusion as it is not implemented.
By default, a server is now sending to its clients the client URLs
of all servers in the cluster. This allows clients to be able
to reconnect to any server in the cluster even if those clients
were not configured with the list of servers in the cluster.
However, there may be cases where it would make sense to disable
this feature. This now can be done with this option/command line
parameter.
Resolves#322
If the server was started with a cluster section in a configuration
file and one would want to override the routes (using `-routes`) the
server would complain that you need to use `-cluster`. Adding
an override of cluster would not work, server would still complain.
Trying to override simply the cluster listen info (without override
of routes) would also not work.
* Configuration requires a cipher suite
* Removed default cipher suites
* Added help to assist with TLS configuration and list available cipher suites.
