| * Remove dead code from SystemServerNeil Fuller2019-11-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove dead code from SystemServer that obstensively protects devices from negative (< 1970) system clock times, but does not. In reality, SystemServer calls SystemClock.setCurrentTimeMillis(), which calls through to the AlarmManager.setTime() binder call. When the code runs the system server hasn't started any services yet, so this would always fail. AlarmManager has similar protections in place that do work: if the device is earlier than a "build time", then the device's clock is forced forward. That provides the protection that the code being removed from SystemServer was trying to achieve. Test: Added logging to SystemClock to prove AlarmManager is null / manual debugging Change-Id: I87dca1062829bc1a10202804fa7ee31e0a6f03a3

* Better handling of NTP-based clocks.Jeff Sharkey2018-02-161-31/+76
| | | | | | | | | | | | | | | | | | | | Now that we have a nice Clock abstraction, we can use it to represent a clock backed by an NTP fix. (This makes testing logic much easier to write.) We now rely completely on NetworkTimeUpdateService to keep our NTP fix up to date, instead of trying to refresh in the middle of critical paths which could trigger random ANRs. Add internal FallbackClock to make it easier to handle missing NTP fixes. Add internal SimpleClock to let implementers focus on single millis() method.

* Extend JobInfo to support NetworkRequest.Jeff Sharkey2017-11-091-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current JobInfo.NETWORK_TYPE values offer basic network selection ability, but more precise requirements continue to come up. Instead of creating more NETWORK_TYPE constants, add support for the existing NetworkRequest object, which is the idiomatic way for an app to express the type of network they'd like to use. Move the implementation details of NETWORK_TYPE constants to use this new NetworkRequest functionality. Deprecate NETWORK_TYPE_METERED, since the lack of the NOT_METERED capability doesn't imply that the connection is metered. (Apps using this API to get to a cellular network should use TRANSPORT_CELLULAR instead.) Add new SystemClock APIs that return java.time.Clock instances for various Android-specific clocks. This gives us a clean interface (with negligible overhead) for swapping in artificial clocks for testing purposes. Improve JobStoreTest to validate new NetworkRequest features, and add one last sanity check to assertTasksEqual() to compare raw bits-on-wire, to catch people who forget to check new fields. Watch for IoThread to go idle to run tests faster. Test: bit FrameworksServicesTests:com.android.server.job. Bug: 67040695 Change-Id: I189e7602132a0ec26d2f0cc6dadc188664961a47

* Move time setting code from SystemClock to AlarmManagerServiceGreg Hackmann2014-02-211-1/+22
| | | | | | | | | | | | | | | | | On devices using /dev/rtc instead of /dev/alarm, updating the time-of-day clock and RTC are separate syscalls. Hence the clock and RTC could be left in inconsistent states if two threads called SystemClock.setCurrentTimeMillis() simultaneously. By moving this code into AlarmManagerService, we can put a global lock around AlarmManagerService.setTime() and prevent the race condition. Note that access to SystemClock.setCurrentTimeMillis() is now gated by android.permission.SET_TIME, where before it was gated by filesystem permissions (i.e., could the process write to /dev/alarm or /dev/rtc).
