Windows has limited support for signals, and does not define syscall.SIGUSR1. Log rotation will be handled differently in windows.
* Add signal.go for all non-windows builds
* Add signal_windows.go for windows builds.
Today, windows looks to be the only platform that does not have syscall.SIGUSR1 defined.
Running `go vet ./...` with `go 1.7.3` would report the following:
```
server/route.go:342: assignment copies lock value to tlsConfig: crypto/tls.Config contains sync.Once contains sync.Mutex
server/server.go:479: assignment copies lock value to config: crypto/tls.Config contains sync.Once contains sync.Mutex
```
Add a “clone” function while waiting for this to be addressed
by the language itself (https://go-review.googlesource.com/#/c/28075/)
In NATS Streaming, we have a test - started early on - that was testing
logging and called SetLogger(l, true, true), then reset by calling
SetLogger(l, false, false) to reset the values. That obviously had not
the expected effect.
During profiling, I noticed that there were tons of allocated
objects due to NATS server debug/trace statements caused by that.
Fixes#304
Changes the non-ASCII curly quotes in the HTML to use the regular ASCII double quotes. Also adds a test to check for the existence of non-ASCII characters in that same HTML.
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
Trying to use IPv6 address for the cluster host would fail.
Also, there were some unclosed channels in case of accept loop
setup failures.
Resolves#323
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.
Clients that will be at the ClientProtoInfo protocol level (or above)
will now receive an asynchronous INFO protocol when the server
they connect to adds a *new* route. This means that when the cluster
adds a new server, all clients in the cluster should now be notified
of this new addition.
