This will protect the server from non NATS clients (telnet, etc),
or misbehaving clients that would create the tcp connection but
block before sending the CONNECT.
The drawback is that the client may or may not receive the error
message (in my tests, it was getting only between 10%-20% of times).
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.
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.
The tool is started with the "-ignore" flag to ignore warning SA2002
which corresponds to invoking t.Fatalf (and the like) in a go routine.
Calling t.Fatalf in a go routine may produce a race condition.
The rationale for ignoring this warning is that if a test executes
the t.Fatalf() line it is that we have a problem either with test
or code that should be fixed.
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.
