This allows changing the cookie domain, maxage and the hash/encryption
keys via the config file.
If no key is provided a new one is generated on each reboot.
But if both keys are provided the session cookies are now valid even
after a server reboot.
Main version can be set in config/default_config.yml
Build version need to be set by build command: go build -ldflags "-X
main.buildversion=$(date -u +.%Y%m%d.%H%M%S)"
Or by using package.sh
Or by using the godep command: godep go build -ldflags "-X
main.buildversion=$(date -u +.%Y%m%d.%H%M%S)"
* New config files
As decided, config files are parsed at runtime.
I decided to go for YAML config files because there can be comments in
it.
There are 2 files:
* config/default_config.yml <= which shouldn't be edited unless we add a
config parameter
* config/config.yml <= which is the user-defined config. This file
shouldn't be commited
Changed every call to config.XXX to config.Conf.XXX (look to the new
stucture of config in config/types.go)
Of course, putting config parameters in config.yml overrides config in
config_default.yml. You don't have to put everything in it, just add
what you want to override.
* Fixing test
Replacing conf.New by config.Conf
* Fixing call to config.Conf to config.Config{} in test files
* Might have fixed testing with this
Printf instead of Fatalf
* Renaming config.yml in example file
* Forbid commiting config.yml
* Should be now fixed
* Do not need this file anymore
