Current V2 watch waits by encoding URL with wait=true.
When a client sets 'no-sync', it requests directly to
proxy and the proxy redirects it by cloning the request
object, which leads to cancel the original request when
it times out and the cloned request gets closed prematurely.
This fixes coreos#3894 by querying
the original client request in order to not use context timeout
when 'wait=true'.
go HTTP library uses type assertion to determine if a connection
is a TLS connection. If we wrapper TLS Listener with any customized
Listener that can create customized Conn, HTTPs will be broken.
This commit fixes the issue.
This commit fixes the issue of creating member dir before validating
the configuration. When member dir exists, it indicates the local etcd
process is a valid etcd member. So we should only create member dir
after we finish configuration validation, joining validation or
discovery validation.
etcd might generate incomplete proxy config file after a power failure.
It is because we use ioutil.WriteFile. And iotuile.WriteFile does
not call Sync before closing the file.
For CoreOS users, they will get a updated version of etcdctl without updating
the etcd server version. And the users cannot really control this behavior.
We do not want to suddenly break them without enough communication.
So we still want the most basic opeartions like get, set, watch of etcdctl2 work
with etcd 0.4. This patches solve the incompability issue.
If headerTimeout is not zero then two context are created but only one is released.
cancelCtx in this case is never released which leads to goroutine leak inside it.
Before this PR, the log is
```
2015/09/1 13:18:31 etcdmain: client: etcd cluster is unavailable or
misconfigured
```
It is quite hard for people to understand what happens.
Now we print out the exact reason for the failure, and explains the way
to handle it.
This attempts to fix#3676. `PrevNoExist` checks if the key previously exists
and if so, it returns an error, which is how `mk` command is supposed to work.
The previous code ignores the previous key and overwrites with the later value.

We use url.ParseQuery to parse names-to-urls string, but it has side
effect that unescape the string. If the initial-cluster string has ipv6
which contains `%25`, it will unescape it to `%` and make further url
parse failed.
Fix it by modifiying the parse process.
Go1.4 doesn't support literal IPv6 address w/ zone in
URI(https://github.com/golang/go/issues/6530), so we only enable tests
in Go1.5+.
