ba629da331d01d74067afdda5d4255682d4b24d7 14-Nov-2013 Christopher Tate <ctate@google.com> Ensure recipient can be launched before attempting broadcast delivery

User removal or eviction inherently races with broadcast delivery. This
patch introduces a latest-possible recheck of the availbility of the
target application before attempting to send it a broadcast.

Once the process has actually been spun up the system is essentially
committed to presenting it as a running application, and there is no
later check of the availability of the app: the failure mode for
continuing to attempt delivery is a crash *in the app process*,
and is user-visible.

We now check the app+userid existence of the intended recipient
just prior to committing to launch its process for receipt, and
if it is no longer available we simply skip that receiver and
continue normally.

db92608de9b4acccee1e3232264c9830ad300c4f 01-Nov-2013 Dianne Hackborn <hackbod@google.com> Fix issue #11168649: LRU logic for Chrome renderers seems...

...not to work on KitKat (was: Janky exit animation)

Reworking the LRU list (splitting it into an activity vs. empty
section) accidentally broken the old behavior of "client activity"
processes being prioritized with activity processes. In fact, we
were no longer marking "client activity" processes at all.

In this change, we rework how we manage "client activity" processes
by putting them on the main activity LRU section. This is generally
simple -- ActiveServices now keeps track of whether a process is
a "client activity" process based on its bindings, and updateLruProcess
treats these as regular activity processes. However, we don't want
to allow processes doing this to spam our LRU list so that we lose
everything else, so there is some additional complexity in managing
that list where we spread client activity processes across is so
that the intermingle with other activity processes.

The rest of the change is fairly simple -- the old client activity
process management is gone, but that doesn't matter because it wasn't
actually running any more. There is a new argument to updateLruProcess
to indicate a client process it comes from (since we now need to update
this based on bindings) which is just used to limit how high in the
LRU list we can move things. The ProcessRecord.hasActivities field is
simply removied, because ProcessRecord.activities.size() > 0 means the
same thing, and that is actually what all of the key mechanisms are using
at this point.

Finally, note there is some commented out code of a new way to manage
the LRU movement. This isn't in use, but something I would like to
move to in the next release so it is staying there for now for further
development.

3bc8f78d7a3d23a67c06221cc41292d04a2fd439 19-Sep-2013 Dianne Hackborn <hackbod@google.com> Implement issue #10691475: Kill cached processes if about to...

...be uncached and too large

When the device is in a low RAM state, when we go to pull a cached
process out to use for some background operation, we can now kill
the current process if we consider its size to be too large.

Note that the current implementation for killing processes is to
just use the same killUnneededProcessLocked() method that we already
have for other things like too many cached processes. This is a
little wrong here, though, because in this case we are at the
point where the caller is actually looking for a process to use.
This current code is not actually removing or cleaning up the
process, so we still need to return the now killed ProcessRecord
and let things fall out from there, which typically means the caller
trying to make an IPC on it and failing and falling into its "oh
no the process died unexpectedly" path. All code using this
*should* be able to handle this correctly, anyway, since processes
really can be killed at any time.

At some point we may to make this implementation cleaner, where it
actually tears down the process right in the call and returns a
null ProcessRecord. That is very dangerous however (we'd need to
go through all paths into this to make sure they are going to be
okay with process state changing on them like that), and I'm not
sure it is really worthwhile. This intention is that killing
processes like this is unusual, due to processes being too large,
and anyway as I wrote all of our incoming code paths must already
be able to handle the process being killed at this point and one
could argue this is just another way to excercise those code paths.
Really, the main negative to this is that we will often have spam
in the log with exceptions about processes dying unexpectedly.
If that is the only issue, we could just add some conditions to
quiet that up at in this case.

We don't want to compute the size of the process each time we try
to evaluate it here (it takes 10s or ms to do so), so there is now
a new field associated with the process to give us the last pss
size we computed for it while it was in the cached state.

To be able to have better cached pss data when we now need it, the
timing for computing process pss has been tuned to use a much
shorter delay for the situations when the process has first switch
into a new state. This may result in us having a fair amount more
pss data overall, which is good, as long as it doesn't cause us to
be computing pss excessively and burning cpu.

Procstats now also has new state to keep track of the number of
times each process has been killed by this new system, along with
the min, avg, max pss of all the times it has happened. This has
slightly changed the checkin format to include this additional data
at the end of pkgkills/prockills lines.

Other changes here:

- Fixed a problem where GPU RAM was not being seen when dumping
the full RAM details of a process. This was because in that
case the system would ask the process to compute its own MemInfo,
which it returned, but the process doesn't have permission to
access the files containing the GPU RAM data. So now the system
always computes the MemInfo and hands it to the app.

- Improved broadcast delays to not apply the delay if the next receiver
of the broadcast is going to run in the same process as the last
one. A situation I was seeing was an application that had two
receivers, one of which started a service; we are better off letting
the second receiver run while the service is running.

- Changed the alarm manager's TIME_TICK broadcast to be a foreground
broadcast. This really should have been anyway (it is supposed to
go out even minute, on the minute, very accurately, for UI elements
to update), and is even more important now that we are doing more
things to delay background broadcasts.

- Reworked how we maintain the LRU process list. It is now divided
into the two parts, the top always containing the processes holding
activities. This better matches the semantics we want (always try
to keep those around modulated by the LRU order we interleave with
other cached processes), and we now know whether a process is being
moved on the LRU list because of an activity operation so we can
only change the order of these activity processes when user operations
happen. Further, this just makes that common code path a lot simpler
and gets rid of all the old complexity that doesn't make sense any
more.

...while setting up a new user from settings.

We can now delay broadcasts when there are enough background services
currently starting (still set to 1 for svelte devices, 3 for normal
devices).

Add new intent flag to not allow receivers to abort broadcasts, which
I use to fix an issue with the initial BOOT_COMPLETED broadcast not
actually requesting pss data at the right time -- it can now be sent
as an ordered broadcast without the ability for the receivers to cancel
it.

The activity manager now keeps a new "process state" for
each process, indicating the general execution and memory
state of the process. This closely follows the out-of-memory
adjustment and scheduling class that it currently tracks,
but roles these together (plus a little more info) into one
more semantically meaningful number.

This value is reported to each process as it changes, so they
can do things like tune the Dalvik garbage collector to match
the current process state.

I think I should also switch to this for process states. It
will give is more meaningful divisions of time for each process.

Also fix a problem in the activity stack where the previous
process was not being set correctly when moving between
activity stacks.

We now keep track of when each process is running, batched
by the current memory status of the device. In addition,
the stats are organized by package first, and then processes
associated with each package inside of that. Finally, we
also keep track of the overall time spent in each memory
status.

This should start to actually get us to some information
we can reach some conclusions about. The total time spent
in each memory status gives us some indication of how much
we are running while memory is low; the new package organization
batched by memory status lets us see what packages have
what processes running when memory is low.

Right now it doesn't really do any of that, just keeps track
of how long every process has been running since boot.

Also update the activity manager to use "cached" as the terminology
for what it used to interchangeably call hidden and background
processes, and switch ProcessMap over to using ArrayMap.

in every single potential app widget in the system being launched...

This is odd because where we do Bundle.writeToParcel(), we are just writing the Parcel
we have with its current length. There is no way this should be able to fail like this...
unless the Bundle is changed while we are running?

Hm.

It looks like the location manager is holding on to Location objects which have a
Bundle of extras. It is that Bundle of extras that the crash is happening on.
And the bundle extras can be changed as it operates. And there are places where
the raw Location object is returned from the location manager, which means the
caller can be olding on to a Location object whose extras can be changed at any
time by other threads in the location manager.

So that seem suspicious.

This change should take care of all these places in the location manager, by
making sure to copy the location object before it goes out of the location
manager.

In addition, add some code to the activity manager to not bring down the entire
system if there is a problem trying to send one of these broadcasts. There is
no need, we can just skip the broadcast as bad.

...Forground Sometimes Doesn't Take

The main change here is a one-liner in ActiveServices to check the
uid when deciding whether to remove an item from mPendingServices.
This could cause the problem being seen -- if the same service for
two users is starting at the same time, the second one would blow
away the pending start of the first one. Unfortunately I have had
trouble reproducing the bug, so I don't know if this is actually
fixing it. It's a bug, anyway.

The reason so much has changed here is because I spread around
logging and printing of the user ID associated with operations and
objects to make it easier to debug these kind of multi-user things.

Also includes some tweaks to the oom manager to allow more background
processes (I have seen many times in logs where we thrash through
processes because the LRU list is too short), plus to compensate an
additional time-based metric for when to get rid of background processes,
plus some new logic to try to help things like Chrome keep around
their service processes.

process.

Packages can be enabled/disabled per user.
This requires maintaining stopped/launched states and
enabled / disabled components and packages per user.

Refactored pm.Settings and PackageSettingsBase to keep
track of states per user.

Migrated the stopped-packages.xml to users/<u>/package-restrictions.xml

Changed intent resolution to handle individual user restrictions.
Bunch of IPackageManager calls now have a userId argument.
Make AppWidgetService handle removals of packages.

Added some tests for pm.Settings and PackageManager.
