Rework idle timeout mechanism, undisable tests

gregw and others added 26 commits June 6, 2023 18:01
 + pass TimeoutException through all APIs
 + HttpConnection now passes on TimeoutException to HttpChannel.onFailure
Signed-off-by: Simone Bordet <[email protected]>
* Improved reset of the earliest timeout before iteration.
* Removed check for getExpireNanoTime() == -1, since it's a valid value.
* When onExpired(Expirable) returns false, the Expirable should arrange to move its timeout in the future.

@lorban @lachlan-roberts The key changes in this PR are:

  • lots of simple mechanical changes to pass TimeoutException instead of Throwable when it is known to be a timeout.
  • Request has been updated to have two types of listeners: for failures and for timeouts. Failures cannot be ignored, timeouts can be.
  • HttpChannelState is where the majority of the changes have been made and to invoke the various listeners.
  • The production of an error response now uses a second ChannelResponse instance. This is to avoid the race where the original handler is still writing to the response whilst an error handler is trying to write the error page for an asynchronously delivered error.

There are quite a few TODOs in the tests, but we can tackle them after the 12.0.0 release.

So LGTM.

This looks unused. Should we keep it nevertheless?

@lorban It has been used before, but now that we don't have listening predicates..... oh but wait yes we do. This should be used by the context addIdleTimeoutListener wrapper that is not implemented!!!! stand by.....

@lorban I've added the context wrapper so idle timeouts are callback in the context. I've also added a test to check that. Please re-review... at least that last commit.


// TODO what do we do about the failing write?
// should timeout errors be non persistent?

I fail to see what this test asserts that the above one (testIdleTimeoutNoListener()) does not.

This one has the idle timeout configured in HttpConfiguration only, so it is testing that it is correctly applied by HttpChannel. I.e the idle timeout between requests is 10x the idle timeout during requests.

(probably could have been parameterised... will do when I next touch this test.)
