Subject: [PATCH] Reconcile WorkSource parcel and unparcel code.
|
||
|
|
|
||
|
|
Prior to this CL, WorkSources would Parcel their list of WorkChains as
|
||
|
|
-1 if null, or the size of the list followed by the list itself if
|
||
|
|
non-null. When reading it back in, on the other hand, they would check
|
||
|
|
if the size was positive, and only then read the list from the Parcel.
|
||
|
|
This works for all cases except when the WorkSource has an empty but
|
||
|
|
non-null list of WorkChains as the list would get written to the parcel,
|
||
|
|
but then never read on the other side.
|
||
|
|
|
||
|
|
If parceling a list was a no-op when empty this wouldn't be an issue,
|
||
|
|
but it must write at least its size into the parcel to know how many
|
||
|
|
elements to extract. In the empty list case, this single element is left
|
||
|
|
unread as the size is not positive which essentially corrupts any future
|
||
|
|
items read from that same parcelable.
|
||
|
|
|
||
|
