| 119 | * Locking within package manager is going to get worse before it gets better. Currently, |
| 120 | * we need to share the {@link PackageManagerService} lock to prevent deadlocks. This occurs |
| 121 | * because in order to safely query the resolvers, we need to obtain this lock. However, |
| 122 | * during resolution, we call into the {@link PackageManagerService}. This is _not_ to |
| 123 | * operate on data controlled by the service proper, but, to check the state of package |
| 124 | * settings [contained in a {@link Settings} object]. However, the {@link Settings} object |
| 125 | * happens to be protected by the main {@link PackageManagerService} lock. |
| 126 | * <p> |
| 127 | * There are a couple potential solutions. |
| 128 | * <ol> |
| 129 | * <li>Split all of our locks into reader/writer locks. This would allow multiple, |
| 130 | * simultaneous read operations and means we don't have to be as cautious about lock |
| 131 | * layering. Only when we want to perform a write operation will we ever be in a |
| 132 | * position to deadlock the system.</li> |
| 133 | * <li>Use the same lock across all classes within the {@code com.android.server.pm} |
| 134 | * package. By unifying the lock object, we remove any potential lock layering issues |
| 135 | * within the package manager. However, we already have a sense that this lock is |
| 136 | * heavily contended and merely adding more dependencies on it will have further |
| 137 | * impact.</li> |
| 138 | * <li>Implement proper lock ordering within the package manager. By defining the |
| 139 | * relative layer of the component [eg. {@link PackageManagerService} is at the top. |
| 140 | * Somewhere in the middle would be {@link ComponentResolver}. At the very bottom |
| 141 | * would be {@link Settings}.] The ordering would allow higher layers to hold their |
| 142 | * lock while calling down. Lower layers must relinquish their lock before calling up. |
| 143 | * Since {@link Settings} would live at the lowest layer, the {@link ComponentResolver} |
| 144 | * would be able to hold its lock while checking the package setting state.</li> |
| 145 | * </ol> |
