"""Scans build output directory for .isolated files, calculates their SHA1
|
|
hashes, stores final list in JSON document and then removes *.isolated files
|
|
found (to ensure no stale *.isolated stay around on the next build).
|
|
|
|
Used to figure out what tests were build in isolated mode to trigger these
|
|
tests to run on swarming.
