Support IPv6 address for ETCD_ADDR and ETCD_PEER_ADDR
pkg/flags: Support IPv6 address for ETCD_ADDR and ETCD_PEER_ADDR
pkg/flags: tests for IPv6 addr and bind-addr flags
pkg/flags: IPAddressPort.Host: do not enclose IPv6 address in square brackets
pkg/flags: set default bind address to [::] instead of 0.0.0.0
pkg/flags: we don't need fmt any more
also, one minor fix: net.JoinHostPort takes string as a port value
pkg/flags: fix ipv6 tests
pkg/flags: test both IPv4 and IPv6 addresses in TestIPAddressPortString
etcdmain: test: use [::] instead of 0.0.0.0
If the TLS config is empty, etcd downgrades https to http without a warning.
This commit avoid the downgrade and stoping etcd from bootstrap if it cannot
listen on TLS.
for transport that are using timeout connections, we set the
maxIdleConnsPerHost to -1. The default transport does not clear
the timeout for the connections it sets to be idle. So the connections
with timeout cannot be reused.
Dial timeout is set shorter because
1. etcd is supposed to work in good environment, and the new value is long
enough
2. shorter dial timeout makes dial fail faster, which is good for
performance
The functionality in pkg/osutil ensures that all interrupt handlers finish
and the process kills itself with the proper signal.
Test for interrupt handling added.
The server shutsdown gracefully by stopping on interrupt (Issue #2277.)
etcd resolves DNS hostnames to IP addresses for client and peer URLs
before creating any listening sockets.
The following messages are logged during startup:
etcd: Resolving infra0.coreos.com:2380 to 10.0.1.10:2380
Fixes#1991
As we move to container-based infrastructure testing env
on travis, the tcp write buffer is more than 1MB. Change
the test according to the change on the testing env.
