2022-11-27: Chrome v108 changes some async methods to synchronous, as
|
||||
documented at:
|
||||
|
||||
https://developer.chrome.com/blog/sync-methods-for-accesshandles/
|
||||
|
||||
We cannot change to the sync forms at this point without breaking
|
||||
clients who use Chrome v104-ish or higher. truncate(), getSize(),
|
||||
flush(), and close() are now (as of v108) synchronous. Calling them
|
||||
with an "await", as we have to for the async forms, is still legal
|
||||
with the sync forms but is superfluous. Calling the async forms with
|
||||
theFunc().then(...) is not compatible with the change to
|
||||
synchronous, but we do do not use those APIs that way. i.e. we don't
|
||||
_need_ to change anything for this, but at some point (after Chrome
|
||||
versions (approximately) 104-107 are extinct) should change our
|
||||
usage of those methods to remove the "await".
