Reland "Use reference counted pointers for ApkAssets"
This reverts commit cf6e79f809034386b04ae551db815ab087f76c0a
Updates:
Prepare the shared pointers for the whole operation at once
instead of re-locking them on each iteration.
Still a regression of about 5% for changing theme's
AssetManager object, vs the original 40%
+ change the log message to a warning as it doesn't break
the app
Original comment:
Use reference counted pointers for ApkAssets
The primary reason for memory corruption is freed ApkAssets
Java expected them to only be freed in the finalizers, but
there are explicit close() calls now, destroying objects that
are still in use in some AssetManager2 objects
This CL makes sure those AssetManagers don't assume ApkAssets
always exist, but instead tries to lock them in memory for any
access
It also adds logging in case of deleting an assets object with
any weak pointers still existing. Those will get into the
bugreports attached to related bugs to help with investigation.
Benchmarks don't regress, and the device appears to be working.
Given that the crashes used to be pretty rare, let's wait for
any new reports or lack of those.
+ add a missing .clang-format file to the jni directory
+ enabled C++23 in the project that uses AssetManager headers
Bug: 197260547
Bug: 276922628
Test: unit tests + boot + benchmarks
