Fixes #1127.
Ideally we would need update the tests but the bare try / except in
StoreBackendBase.dump_item
makes this difficult and looks like an anti-pattern anyway. However I am not sure which exception we should expect in case of a race condition in the creation of directory (probablyOSError
?). We probably need more tests, including multi-threaded stress tests to check for the robustness of concurrent directory creation.@aabadie if you are still interested in this, please feel free to send a PR :)
