Motivation:
- ServerConfig is part of 'embed' public API, while etcdserver is more 'internal'
- EtcdServer is already too big and config is pretty wide-spread leaf
if we were to split etcdserver (e.g. into pre & post-apply part).
In these unit tests, goroutines may leak if certain branches are chosen. This commit edits channel operations and buffer sizes, so no matter what branch is chosen, the test will end correctly. This commit doesn't change the semantics of unit tests.
* Turn off checking of format of commit message.
* scripts/fix.sh: Fix fixing whitespaces in *.sh scripts
Aparently there is a difference between:
find ./ -print0 -name *.sh and
find ./ -name *.sh -print0
* etcdserver unit tests: Do not call .Fatalf(...) from not test's goroutine.
Fixes following test failures:
