580ea321b16c71ddec515553761d6f37359bd3a0 26-Feb-2018 Yao Chen <yaochen@google.com> Add StateTracker.

StateTracker is a special condition tracker that's based on a state atom.
State atoms are annotated in atoms.proto.

The rules for StateTracker:
1. must not have "stop". must have "dimension"
2. must be based on a state atom.
3. it must have the all primary fields and the exclusive state field in its dimension.

For example UidProcessStateTracker, will have output dimension {uid, state}.

Test: unit tests added.

The key change is to revamp how we parse/store/match a log event, especially how we match repeated
field and attribution nodes, and how we construct dimensions and compare them.

+ We use a integer to encode the field of a log element. And also encode the FieldMatcher into an
integer and a bit mask. The log matching becomes 2 integer operations.

+ Dimension is stored as encoded field and value pair. Checking if 2 dimensions are equal is then
becoming checking if the underlying integers are equal. The integers are stored contiguously
in memory, so it's much faster than previous tree structure.

Start review from FieldValue.h

Test: statsd_test + new unit tests

+ StatsdStats is the global class that tracks the stats about statsd.

+ Added guardrail for classes that have a map which could potentially grow
unboundedly with the number of logs.

TODO: add unit tests & CTS for StatsdStats, and guardrail
add stats for pulled atoms.

c18abedfe29eb51fec14797ecf0bb101d22900b2 23-Nov-2017 David Chen <dwchen@google.com> Fixes out of range bug in SimpleConditionTracker.

One of the unit tests was flaky because mStopAllLogMatcherIndex may
be greater than the size of eventMatcherValues, so we access an
element that is greater than the vector size.

Test: Check unit-tests still work. Flake is a bit hard to find.

5154a379303ab90a2b2914676a4441917a329b5d 31-Oct-2017 Yao Chen <yaochen@google.com> Adding multi layer aggregation in DurationMetric

Newly supported metrics examples:

1) Compute [Total|Max] duration of [an app] holding [ANY] wake lock while [this app] is in
[background] and [screen off], bucket size 30seconds, and slice output by uid.

2) Compute [Total|Max] duration of [ANY app] holding [ANY] wake lock while [this app] is in
[background] and [screen off], bucket size 30 seconds.

+ DurationMetric proto has a "what" which is a SimpleCondition. It defines the atom level start
and stop of the duration timer, and it has its atom dimension. e.g., for wake locks, the atom
dimensions wil be uid and wl name.

+ Now dimension is explicitly specified in SimpleCondition proto instead of inferred from the "link"

+ Added support for "Or" and "Max" through 2 layers of aggregation.

TODO: (1) The way we track slicedCondition in duration metric is not efficient. optimize!
(2) The output dimension should all use int32 instead of KeyMatcher. Fix in a future cl.

Test: Added some unit tests using gmock. Will add more unit tests.

5110bedd787835d4dbc809b7977285cac364bdef 23-Oct-2017 Yao Chen <yaochen@google.com> Add EventMetricProducer

+ Started to use ProtoOutputStream in EventMetricProducer.
[TODO]: We need to auto-generate fieldIds for StatsLogReport, XXXMetricData, etc.
[TODO]: We need to add Enum type to liblog, otherwise we cannot reconstruct a proto containing
an enum

+ Some refactor in metric initialization code. There are still boiler plate code, because Metrics
are similar but with subtle differences.

Now we support following metrics:
<Duration> of [app holding a wake lock], while [*this app*] is [in background] [AND] [screen is off]
[Slice] the output by [app name, wake lock name], with bucket size [30sec]

+ Also added onDumpReport() api in MetricsManager, it can be called from client to fetch the data from
statsd

+ Also added command line tool to dump the StatsLogReport from all metrics for debugging.

+ Synced proto from google3. with a pending cl (cr/172359050)

TODO: We need to add tons of tests to test the Metrics. I will work on it after this CL so people
can be unblocked.

I locally test the duration metric with wake lock with an app that generates StatsLog events.

Test: statsd_test

and manual test, and run:

adb shell cmd stats dump-report
We have a default config, which contains a metrics to count PROCESS_START event sliced by
package name.

9fc9edf95a308f5884bf541cac81ce1f41aba0ba 16-Oct-2017 Joe Onorato <joeo@google.com> Clean up how we handle configurations, and other assorted cleanup

- Add a ConfigManager class that tracks the configurations
that have been passed to us. Configurations are now
tracked by tuples of (uid,tag), where the tag is an
app-defined string, in case a single uid has multiple
configurations.
- Move all of the initialization into StatsService.
- Get rid of the ability to have multiple LogListeners. Raw
events are now pushed directly into StatsService, which
can distribute them to the interested parties (and will
eventually be able to do the proper locking).
- Add Log.h, which sets our LOG_TAG correctly.
- Move some of the related files that I expect will grow some
into their own subdirectories.

+ also synced proto from google3 to fix the LogEntryMatcher proto

+ MetricsManager represents StatsdConfig, it's responsible for initializing and managing all
LogEntryMatcher, Condition, and Metrics. Start review from here.

+ Added more complete StatsdConfig initialization, including building the map for:
LogEntryMatcher -> Metrics
LogEntryMatcher -> Condition
Condition -> Metrics.

All the maps use index(int). The extra amount of memory for storing mappings help us
quickly process log events.

The StatsdConfig initialization process detects malformed config
- Circle dependency
- Missing definition
etc.

And once we detect ANY error, statsd will reject the config. And the resources related to this
config will be released.

Test: Added unit tests
