------------------------------------
Summary: Fix TAsyncClientManager timeout race
Key: THRIFT-2108
URL: https://issues.apache.org/jira/browse/THRIFT-2108
Project: Thrift
Issue Type: Bug
Components: Java - Library
Affects Versions: 0.9
Reporter: Vadim Spivak
TAsyncClientManager uses a TreeSet(timeoutWatchSet) for managing timeouts with
a comparator based on the timeout timestamp. However, this timestamp can be
mutated externally by changing the client timeout before TAsyncClientManager
tries to remove (and fails) the TAsyncMethodCall from the timeout set.
Failing to delete the TAsyncMethodCall from the timeoutWatchSet will break some
timeouts and cause some callbacks to fire twice, once with onComplete and a
second time with onError.
The common use case when this happens is if you want to issue a new request
with a different timeout to the same client inside an onComplete callback.
