A blocking driver's calls reach the worker on a many-producer stack and its results come back on another; the worker parks on an eventcount when the sync is still open and the queue is empty, and leaves once it ends. A call queued as the worker leaves either starts a new worker or is taken by the leaving one. cloud_sync_deinit() waits for the worker on an eventcount, still bounded by its timeout. Without pointer atomics the calls run directly, as without threads. The async test queues a sync from the worker's leaving point.

# Regression tests for cloud sync:
|
|
# - cloudsync_savefile_owner_test: the save-file ownership predicate
|
|
# cloud sync consults before it replaces or removes a local file, and
|
|
# the manifest key lookup its carry-forward depends on.
|
|
# - cloudsync_path_safety_test: the manifest-key path-traversal guard
|
|
# (tasks/task_cloudsync_path.c, #included by the test).
|
|
# - cloudsync_manifest_adds_test: entries added to the updated
|
|
# manifests from several threads at once, with no lock
|
|
# (tasks/task_cloudsync.c, #included by the test).
|
|
# - cloudsync_pacing_test: the diff runs as much as the shared
|
|
# per-frame I/O window grants, hashing large files a chunk at a time
|
|
# (tasks/task_cloudsync.c, #included by the test).
|
|
# - cloudsync_async_test: a blocking driver's calls run on a worker
|
|
# and complete through cloud_sync_poll() on the caller's thread
|
|
# (network/cloud_sync_driver.c).
