- Now aggregate number of times each process has crashed and ANRed.
- Now aggregate total number of connectivity changes.
- Now record connectivity changes in the history.

Crash and ANR counts are new entries at the end of "pr" in checkin.

Connectivity change counts is a new entry at the end of "m" in checkin.

Connectivity changes in the history checkin are Ecn and include the
type of connection and its state.

- Fix per-process dumping of meminfo to have an option to interpret
the input as a package, so including all processes that are
running code of that package.
- Fix top-level per-package debug output to correctly include all
of these improvements and give them a little more time (10s) to
complete for timing out.

..."uid 2000 does not have android.permission.UPDATE_DEVICE_STATS"

Make sure to clear calling identity before getting into the guts
of the activity manager. Also fix the places the activity manager
calls in to battery stats to not require a permission check, anyway.

d953c53d3b04d772bb1b62ede1c2011641ca82b5 17-Aug-2014 Dianne Hackborn <hackbod@google.com> Work on issue #16629489: Google (Play?) Services eating through battery

There is a bug in how we deal with name overflows combined with resetting
the battery stats data. If we do a reset while a wakelock is being
actively held that has been put into the overflow bucket, then we can
end up reducing the number of known wake locks in the list so when after
that it is released we try to release it under its real name rather than
the overflow name.

This means we need to keep track of which wake locks have been placed
in the overflow bucket while they are actively being used, so we can be
sure to properly handle it as part of that bucket until it is eventually
released.

This makes things... somewhat more complicated. So now we have a class
to take care of all these details, and also use it for other places where
we have the same overflow semantics sync and job stats.

Also fix potential deadlock -- BatteryStatsHelper needs to call on to
ConnectivityManager to find out of there is telepohny, however we use
that class when doing a dump while the battery stats lock is held. To
fix this, we check the connectivity state up in the battery stats service
before acquiring the lock and propagate that information through to the
dump code.

- No longer track process starts/stops normally.
- Increase buffer size to 256KB.
- Buffer size increase requires reworking how battery stats
are retrieved, since it is going to be hitting IPC limits.
- Also, store the last full stats after a reset, to be reported
at the next checkin.
- Also, discharge and charge times are tagged with the screen
and battery save state during that time.

But wait, there's more!

- Keep track of sync durations in the aggregated stats.
- Add events for users that are running and in the foreground.
- Rework the activity manager's tracking of stuff using
battery in the background to be based on proc stats, which
allows it to be better about determing when it should reset
its tracking of background work.
- Also add tracking of scheduled job execution, like we are
doing for syncs.
- And once I started hooking battery stats in to
JobSchedulerService, I found a few things I couldn't stop myself
from changing: (1) make it very explicit that it doesn't start
scheduling jobs until we have reached the point in system boot
where third party apps are allowed to run, and (2) adjust
the various for loops to not use iterators.

61659e5daaea80104d4d0fd567e78b5f757b5df4 10-Jul-2014 Dianne Hackborn <hackbod@google.com> Add tracking of uid process states in battery stats.

We now keep track of how long each uid had processes in
various states: foreground, active, running. This is based
on a collapse of the various activity manager process states
into these three bins.

You'll see these in a checkin like this:

8,10013,l,st,61504,61504,83109

Also fix issue #16021555: App showing up as on "top" even
when the screen is off. This is "fixed" by just saying we
always report the current app at the top of the activity stack,
regardless of the state of the screen.

3251b9075246841a7b1ddecf10859b1abd858f33 20-Jun-2014 Dianne Hackborn <hackbod@google.com> Add some wifi tracking to battery stats.

Now track supplicant state and wifi signal strength.
Output looks like this:

+12m45s235ms (1) 095 +wifi_full_lock +wifi_running wifi_signal_strength=3 wifi_suppl=scanning
+12m46s095ms (1) 095 -wifi_full_lock wifi_suppl=associated
+12m46s469ms (2) 095 wifi_suppl=completed +proc=u0a74:"com.google.android.videos"
+12m52s103ms (1) 095 +wifi_full_lock wifi_suppl=disconn

Also modify history dump so that when we hit a RESET or START
command, we clear our previous history data, so the next event
will include new data. This means if you are scanning through
the output, you must at this point clear any binary stats you
have like "running" or "wake_lock" or else you will continue to
think they are on until whatever point later they get turned on
and then back off.

And a small bug fix in proc stats that would cause the system
process to crash.

2c43c339de5aaf4fef58aa9b5ac3af48609263a8 13-Jun-2014 Jeff Brown <jeffbrown@google.com> Resolve boot time dependencies related to the power manager.

This change fixes a bug where native daemons may try to communicate
with the power manager before it was fully initialized due to a race
between publishing the binder service and completing init().

The solution was to simplify the dependencies related to the power
manager. It turns out that most services that were passed in
init are not actually needed until systemReady. What remained
was a dependency on the activity manager to check permissions for
incoming calls. So now we start activity manager first.
However, the activity manager also depends on power manager for
wakelocks. To break the cycle, we now defer initializing the activity
manager's wakelocks until after the power manager has been started.

Cleaned up a bunch of boot-time service dependencies so that we
can have better confidence that they are correctly maintained.

- Now the full wake history uses the history tag if it can.
Hopefully this will still result in a consistent history,
since that isn't really want the tag is for... but the
current implementation in places will probably make this work.

- Possibly fix a bug with inconsistent state between partial
history snapshots: after a snapshot is printed, don't allow
any more batching into the most recent history entry, so the
next snapshot will not miss anything that might get placed
into it soon after.

Also rework command line arguments for enable/disable to make these
commands instead of options.

Fixes an issue where dozing was treated the same as the screen
being fully on. Now dozing is treated the same as the screen
being fully off which is slightly better. The decision of how
to represent this state is now internal to the battery stats
so it can be improved later.

Removed noteInputEvent() since it is unused.

a1bd79268be693f04f4adee90673d6ed400cc9fd 21-Mar-2014 Dianne Hackborn <hackbod@google.com> Battery stats: track actually running time

Use the uptime while creating the battery stats history to
generate a new event indicating when the CPU is actually running.
We can do this in combination with the new event reporting when
the CPU comes awake, looking at the difference between the
uptime and elapsed time at that point to determine when it last
when to sleep.

Also use this information to generate a new set of aggregated
states, the uptime caused by each wake reason.

Finally use new radio down timestamp to adjust the times we
compute for radio use. Note that this information is not (yet)
being used to adjust how these are recorded in the history.

When the work source of a wake lock was changed, this would
cause the old wake lock to be released in battery stats before
the new one was acquired (the power manager would correctly
keep holding the associated wake lock). This resulted in a
pointless entry in the battery history showing the last wake
lock being released and a new one acquired.

This change adds a new path in to battery stats to report
when a wake lock has changed, allowing it to acquire the
new wake locks first before the old ones, so it can't drop
down to zero wake locks. This also provides better timing
information, as the same current time can be used for both
operations.

In addition, added a new kind of history entry for the
current time, so you can tell when in actual world clock
time the battery data is happening.

Depends on a modification to libsuspend so that we can get
a callback each time the device wakes up, to read the current
wakeup reasons from the kernel. These are then stuffed in
to a new field in the battery history.

Also add new dump options --history-start and --charged
to better control what is dumped.

Finally the alarm manager uses a "*walarm*" tag for history
item wake locks that are coming from a wakeup alarm.

Also add new API for determining whether the current data network
is active, and thus better scheduling network operations. This
API is designed to not be tied to a mobile network -- regardless
of the network, apps can use it to determine whether they should
initiate activity or wait. On non-mobile networks, it simply always
reports as the network being active.

This changed involved reworking how the idle timers are done so
that we only register an idle timer with the current default
network. This way, we can know whether we currently expect to
get callbacks about the network being active, or should just always
report that it is active. (Ultimately we need to be getting this
radio active data from the radio itself.)

We now always turn on network state tracking for mobile,
and push this information down to battery stats.

In battery stats we use this to both log the changes in
the history and keep track of the total time the mobile
radio was active.

Power computation is switched over to using this information
to help determine power use, which will hopefully make it
more accurate (not counting inaccuracies in knowing when it
actually goes down).

Note yet done is aggregating this data per-uid, to better
emphasize which apps are causing the radio to be up. Right
now we just spread the total time across all uids weighted
by the total number of packets they have sent and received.

Also put in the battery stats infrastructure for bluetooth to

We now try to have a better label for the first wake lock
that is acquired in the log. This is done in two ways:

- The alarm manager now sorts the alarms it is going to
execute so that wakeup alarms are first, which are more
important w.r.t. which one should be logged.
- There is a new power manager facility to make a wake lock
as "unimportant for logging," which just means in battery
stats that a wake lock acquired after that can be considered
the actual one to log. This is only used by the alarm manager
to mark its TIME_TICK alarms as unimportant for logging.

Also reworked the battery history code to be cleaner and a bit
smaller. There is no longer a separate EVENT command, instead
the event code and tag are just another thing that can be included
in an UPDATE command.

The bits used in the first history int are also re-arrange, so
that only the ones that really change a fair amount in the state
bits are up at the top and there is no longer space used for
the command code (since now it is always just UPDATE). This
allows us to have more room for the time delta at the bottom,
to better avoid situations where we need to write an int delta.
