WaitForResult expects body to fail and retries few times before giving
up. Assertions inside the testfn body causes it to terminate abruptly
without retrying.
`currentExpiration` field is accessed in multiple goroutines: Stats and
renewal, so needs locking.
I don't anticipate high contention, so simple mutex suffices.
Since d335a82859ca2177bc6deda0c2c85b559daf2db3 ScriptExecutors now take
a timeout duration instead of a context. This broke the script check
removal code which used context cancelation propagation to remove
script checks while they were executing.
This commit adds a wrapper around ScriptExecutors that obeys context
cancelation again. The only downside is that it leaks a goroutine until
the underlying Exec call completes or timeouts.
Since check removal is relatively rare, check timeouts usually low, and
scripts usually fast, the risk of leaking a goroutine seems very small.
Some tests have containers that die almost immediately, and may die
and cleaned up before `driver.WaitUntilStarted` runs.
The causes for container dying seems special for each test:
* TestDockerDriver_Cleanup: `hello-world` image just emits a message and exits immediately
* TestDockerDriver_ForcePull_RepoDigest: the busybox image in `TestDockerDriver_ForcePull_RepoDigest` test didn't support `-p 0` argument
* TestDockerDriver_Entrypoint: with the entrypoint being `/bin/sh -c`, the command needs to be the entire string; otherwise, it ignores the comments

The removal of the inner context made the remaining cancels cancel the
outer context and cause script checks to exit prematurely.
Currently, libcontainer-based executor, upon shutdown, kills the
container initial process. The children of the killed process remain
running, and the executor is never marked as terminated until they do.
Also, fix a case where we treat processes as successful, when
`proc.Wait()` fails. In some attempts, I was getting "waitid no child
processes" errors and such error shouldn't get process to be considered
successful.
this allows us to drop a cyclical import, but is subobptimal as it
requires BaseDriver tests to move. This falls firmly into the realm of
being a hack. Alternatives welcome.
This removes a cyclical dependency when importing client/structs from
dependencies of the plugin_loader, specifically, drivers. Due to
client/config also depending on the plugin_loader.
It also better reflects the ownership of fingerprint structs, as they
are fairly internal to the fingerprint manager.
The logging package is used by logmon and the legacy mock_driver. Because the
legacy drivers are going away, I'm moving it here to signify its actual
ownership.
As part of deprecating legacy drivers, we're moving the env package to a
new drivers/shared tree, as it is used by the modern docker and rkt
driver packages, and is useful for 3rd party plugins.
