| /** |
| * Keep track of all those APKs everywhere. |
| * <p> |
| * Internally there are two important locks: |
| * <ul> |
| * <li>{@link #mPackages} is used to guard all in-memory parsed package details |
| * and other related state. It is a fine-grained lock that should only be held |
| * momentarily, as it's one of the most contended locks in the system. |
| * <li>{@link #mInstallLock} is used to guard all {@code installd} access, whose |
| * operations typically involve heavy lifting of application data on disk. Since |
| * {@code installd} is single-threaded, and it's operations can often be slow, |
| * this lock should never be acquired while already holding {@link #mPackages}. |
| * Conversely, it's safe to acquire {@link #mPackages} momentarily while already |
| * holding {@link #mInstallLock}. |
| * </ul> |
| * Many internal methods rely on the caller to hold the appropriate locks, and |
| * this contract is expressed through method name suffixes: |
| * <ul> |
| * <li>fooLI(): the caller must hold {@link #mInstallLock} |
| * <li>fooLIF(): the caller must hold {@link #mInstallLock} and the package |
| * being modified must be frozen |
| * <li>fooLPr(): the caller must hold {@link #mPackages} for reading |
| * <li>fooLPw(): the caller must hold {@link #mPackages} for writing |
| * </ul> |
| * <p> |
| * Because this class is very central to the platform's security; please run all |
| * CTS and unit tests whenever making modifications: |
| * |
| * <pre> |
| * $ runtest -c android.content.pm.PackageManagerTests frameworks-core |
| * $ cts-tradefed run commandAndExit cts -m CtsAppSecurityHostTestCases |
