This commit adds basic sentry reporting. If enabled by setting the
appropriate configuration value, it will report panics and errors.
Certain functions in the core package (Delegate, Encrypt, Decrypt,
Restore, and ResetPersisted) have additional Sentry reporting as
these are the most common errors.
+ If a valid hipchat configuration is provided, send a message when
Red October has restarted.
+ If persistence is inactive, alert the channel that this is the case.
This is a rather large change. It consists of the following changes:
+ Direct access to the keycache has been removed from the core
package. This forces all interaction with the cache to go
through the Cryptor, which is required for persistence. The
Cryptor needs to know when the cache has changed, and the only
way to do this effectively is to make the Cryptor responsible
for managing the keycache.
+ A new persist package has been added. This provides a Store
interface, for which two implementations are provided. The
first is a null persister: this is used when no persistence
is configured. The second is a file-backed persistence store.
+ The Cryptor now persists the cache every time it changes.
Additionally, a number of missing returns in a function in the core
package have been added.
This simplifies our deployment process, allowing us to use existing
configuration management tools designed for templating command-line
parameters to template the config files in a straightforward manner.
This pull request adds a status endpoint to the Red October server; as
of this pull request, the status endpoint only returns the current
delegation persistence state. The HTTP UI has not been updated, as
this is scoped out for a future request; however, the CLI utility now
features a status command to fetch this information.
