d6385a54cb bitbake: runqueue: show number of currently running bitbake threads when pressure changes
* it might be a bit confusing as it shows number of threads before making
  the decision to start more tasks and also it can show only a few tasks
  running, but not because of pressure when there just aren't many tasks
  left or wait for their dependencies to be finished first

* example output:
  NOTE: Pressure status changed to CPU: True, IO: None, Mem: None (CPU: 297589.5/200000.0, IO: 5522.2/None, Mem: 779.2/None) - using 7/8 bitbake threads
  NOTE: Pressure status changed to CPU: False, IO: None, Mem: None (CPU: 196381.2/200000.0, IO: 2667.9/None, Mem: 556.2/None) - using 2/8 bitbake threads

acd993f24c bitbake: runqueue: show more pressure data
* with latest bitbake I'm seeing very low number of bitbake tasks
  executed in parallel, probably due to pressure regulation
  show the values this is based on in the note

* also simplify a bit by counting the pressure and exceeds signs
  only once

98223b776a bitbake: runqueue.py: fix PSI check logic
The current calculation is not correct because if tdiff is less than
1.0, it's not taken into consideration when calculating the current
pressure.

Also, make it clear that the 1.0s is the psi accumulation cycle,
which might be changed in the future. We have this cycle because it
could largely avoid the 0 result issue, that is, if the interval
between checks are too small, the result might be 0. With this
accumulation logic, which has been there but let's make it clear,
this 0 result problem could be mitigated.

a76bc698c4 bitbake: runqueue: fix PSI check calculation
The current PSI check calculation does not take into consideration
the possibility of the time interval between last check and current
check being much larger than 1s. In fact, the current behavior does
not match what the manual says about BB_PRESSURE_MAX_XXX, even if
the value is set to upper limit, 1000000, we still get many blocks
on new task launch. The difference between 'total' should be divided
by the time interval if it's larger than 1s.

Using multiconfig to target baremetal pieces of the system and building

To clean up the output and to reduce risk of missing important warnings,

3a3afebf41 bitbake: bitbake-worker/runqueue: Avoid unnecessary bytes object copies
declaring queue=b"" creates an object of types bytes().
bytes() is an immutable object, and therefore doing "self.queue = self.queue + r"
creates a new object containing "self.queue" concatenated with "r".

On my test setup, we are passing 180MB of data of "workerdata" to the bitbake-worker,
so those copies significantly slow down the initialization of the bitbake-worker.

Rather use bytearray() which a mutable type, and use extend() to avoid copies.
In my test setup, byterray.extend() is 10.000 times faster than copying the queue,
for a queue size of 180MB.

201362ccb6 bitbake: runqueue: Fix deferred task/multiconfig race issue
If there are several multiconfigs in play for example a non-multiconfig with
a task with one hash and then three multiconfigs for the same task, different
architectures but the same hash (different to the non-mc), the three mcs
will be deferred until after the non-mc task but then will all run together
and race against each other.

Change the code to re-enable deferred tasks one at a time. This way, if they do
race, they won't run in parallel against each other.

6282ef6c7c bitbake: runqueue: Fix race issues around hash equivalence and sstate reuse
We identified a use case where a native recipe (autoconf-native) was
rebuilt with no change in output yet the sstate for do_package tasks
wasn't being used.

The issue is that do_package tasks have a hard dependency on
pseudo-native:do_populate_sysroot. That task was one of the many
tasks being rehashed when autoconf-native's hash was changed.

If update_tasks processed a recipe before it had processed pseudo-native,
that recipe would be marked as not possible from sstate and would
run the full tasks.

The fix is to split the processing into two passes, first to handle
the existing covered/notcovered updates, then in the second pass,
check whether there are "harddep" issues.

This defers the do_package tasks until after pseudo-native is installed
from sstate as expected and everything works well again.

c4745d9c7d bitbake: runqueue: Drop deadlock breaking force fail
I'm 99% certain this failing of a scenequeue task corrupts runqueue and
causes all kinds of breakage. I'd rather runqueue deadlocked than corrupted
and did weird things so drop this code.

We've seen builds where the deadlock triggers and it then tries to run tasks
where the SQ task already ran with very confusing failures. It is likely it
is this code causing it.

74883eca07 bitbake: runqueue: Fix unihash cache mismatch issues
Very occasionally we see errors in eSDK testing on the autobuilder where the task
hashes in the eSDK don't match what was just built. I was able to inspect one of
these build directories and noticed that the bb_unihashes.dat file in the eSDK
was zero sized. Whilst inspecting the code to understand the cause, I noticed that
updated hashes are not saved out in subsequent updates of the values in the rehash
process.

Add a missing sync call to ensure this happens.

2e193726bd bitbake: bitbake: runqueue: add memory pressure regulation
Prevent new tasks from being scheduled if the memory pressure is above
a certain threshold, specified through the "BB_MAX_PRESSURE_MEMORY"
variable in the conf/local.conf file. This is an extension to the
following commit and hence regulates pressure in the same way:
   48a6d84de1 bitbake: runqueue: add cpu/io pressure regulation

Memory pressure is experienced when time is spent swapping, refaulting
pages from the page cache or performing direct reclaim. This is why
memory pressure is rarely seen but might be useful as a last resort to
prevent OOM errors.

3b18438166 bitbake: bitbake: runqueue: add cpu/io pressure regulation
Prevent the scheduler from starting new tasks if the current cpu or io
pressure is above a certain threshold and there is at least one active
task. This threshold can be specified through the
"BB_PRESSURE_MAX_{CPU|IO}" variables in conf/local.conf.

The threshold represents the difference in "total" pressure from the
previous second. The pressure data is discussed in this oe-core commit:
   061931520b buildstats.py: enable collection of /proc/pressure data
where one can see that the average and "total" values are available.
From tests, it was seen that while using the averaged data was somewhat
useful, the latency in regulating builds was too high. By taking the
difference between the current pressure and the pressure seen in the
previous second, better regulation occurs. Using a shorter time period
is appealing but due to fluctations in pressure, comparing the current
pressure to 1 second ago achieves a reasonable compromise. One can look
at the buildstats logs, that usually sample once per second, to decide a
sensible threshold.

If the thresholds aren't specified, pressure is not monitored and hence
there is no impact on build times. Arbitary lower limit of 1.0 results
in a fatal error to avoid extremely long builds. If the limits are higher
than 1,000,000, then warnings are issued to inform users that the specified
limit is very high and unlikely to result in any regulation.

The current bitbake scheduling algorithm requires that at least one
task be active. This means that if high pressure is seen, then new tasks
will not be started and pressure will be checked only for as long as at
least one task is active. When there are no active tasks, an additional task
will be started and pressure checking resumed. This behaviour means that
if an external source is causing the pressure to exceed the threshold,
bitbake will continue to make some progress towards the requested target.
This violates the intent of limiting pressure but, given the current
scheduling algorithm as described above, there seems to be no other option.
In the case where only one bitbake build is running, the implications of
the scheduler requirement will likely result in pressure being higher
than the threshold. More work would be required to ensure that
the pressure threshold is never exceeded, for example by adding pressure
monitoring to make and ninja.

The runbuild option handling in runqueue was flawed as items deleted from the

Rather than modify runtaskentries straight away, compute a new shorted list

back to the list meaning delcount can be simplifed to a simple counter.

The second use case in runonly doen't re-add items so doesn't have this

34e4eebc32 bitbake: lib/bb: Fix string concatination potential performance issues
Python scales badly when concatinating strings in loops. Most of these
references aren't problematic but at least one (in data.py) is probably
a performance issue as the issue is compounded as strings become large.

The way to handle this in python is to create lists which don't reconstruct
all the objects when appending to them. We may as well fix all the references
since it stops them being copy/pasted into something problematic in the future.

This patch was based on issues highligthted by a report from AWS Codeguru.

15c87c405f bitbake: runqueue: Clean up task stats handling
When we parallelised normal and setscene tasks, the task stats
handling was left separate pending further thought. We had to remove
handling of the setscene tasks from the UI in order to maintain
consistent task numbering.

Currently, "0 of 0" tasks can be shown as setscene tasks execute
until the first normal task runs.

The only use left for sq_stats is in the active task numbers which
we can use the length of sq_ive for instead. We can therefore
drop it and return stats in all cases. This removes the "0 of 0" task
problem since the stats in all normal and setscene tasks matches.

fd9c3a5a14 bitbake: runqueue: Fix issues with multiconfig deferred task deadlock messages
In multiconfig builds with large numbers of identical tasks, builds were
deadlocking after recent runqueue changes upon rebuilds where there was
heavy sstate usage (i.e. on second builds after a first completed).

The issue was that deferred tasks were being left indefinitely on
the deferred list. The deadlock handler was then "breaking" things
by failing tasks that had already succeeded, leading to the task
being on both covered and not covered lists, giving a further error.

The fix is to clean up the deferred task list when each setscene task
completes. I'd previously been hoping to avoid iterating that list
but it appears unavoidable.

7e599a1feb bitbake: runqueue: Avoid deadlock avoidance task graph corruption
If the deferred task deadlock avoidance code triggers, it could mark an executed
task as failed which leads to "covered and not covered" error messages. Improve
the logic so if the deadlock code is triggered, it doesn't cause the errors.

a15eea5077 bitbake: runqueue: Improve multiconfig deferred task issues
The previous patches have exposed new issues with this code path,
the issues being around what should happen when the hash of a task
changes and the task is or is not on the deferred task list.

Rather than rebuilding the deferred task list during each rehash
event, build it once at the start of a build. This avoids the problem
of tasks being added back after they have run and also avoids problems
of always ensuring the same task is deferred. It also allows the
'outrightfail' codepath to be handled separately as the conditions
are subtly differnt.

One significant win for the new approch is the build is not continually
printing out lists of deferred tasks, that list remains fairly static
from the start of the build. Logic is added in to ensure a rehashed
task with a hash matching other deferred tasks is deferred along with
them as a small optimization.

An interesting test case for this code was reported by Mark Hatle
with four multiconfigs, each the same apart from TMPDIR and running a
build of:

bitbake buildtools-tarball mc:{one,two,three,four}:core-image-minimal

which is interesting in that the build of buildtools partially overlaps
core-image-minimal and the build has a rehash event for qemuwrapper-cross
even without any external hash equivalence server or preexisting data.

93aaa5e994 bitbake: runqueue: Handle deferred task rehashing in multiconfig builds
If the hash of a task changes and that hash is a deferred task (e.g. a multiconfig
build), we need to ensure that the hash change propagates through to all the tasks
else the build will run multiple copies of the task, sometimes with oddly differing
results as the outhashes of native tasks built in differing locations can confuse
things.

76891afd76 bitbake: runqueue: Fix multiconfig deferred task sstate validity caching issue
We were testing the validity of deferred tasks setscene status "up front" which
is very unlikely to succeed and leads to cache invalidation issues. With the
change to rebuild the deferred task list, this status becomes out of sync. The
result was tasks being executed when they should not have been leading to extra
work for the build unnecessarily.

Instead, don't process validity status for deferred tasks and assume their
data will become available. If it doesn't, this will now result in a build
error as the setscene task will fail and the main task will run instead.

In theory we could try and track the state changes in the deferred list and
re-test validity then but I'm not sure it is worth the effort when the other
code path and errors in setscene tasks will give a pretty good idea of what
is happening anyway.

7ea37b9291 bitbake: runqueue: Fix deferred task issues
In a multiconfig situation there are circumstances where firstly, tasks
are deferred when they shouldn't be, then later, tasks can end up as
both covered and not covered.

This patch fixes two related issues. Firstly, the stamp validity checking
is done up front in the build and not reevaulated. When rebuilding the
deferred task list after scenequeue hash change updates, we need therefore
need to check if a task was in notcovered *or* covered when deciding to
defer it. This avoids strange logs like:

NOTE: Running setscene task X of Y (mc:initrfs_guest:/A/alsa-state.bb:do_deploy_source_date_epoch_setscene)
NOTE: Deferring mc:initrfs_guest:/A/alsa-state.bb:do_deploy_source_date_epoch after mc:host:/A/alsa-state.bb:do_deploy_source_date_epoch

where tasks have run but are then deferred.

Since we're recalculating the whole list, we also need to clear it before
iterating to rebuild it. By ensuring covered tasks aren't added to the
deferred queue, the covered + notcovered issue should also be avoided.
in the task deadlock forcing code.

9982b2c0f2 bitbake: runqueue: Further fixes for confused setscene tasks
There is further evidence of tasks ending up being "covered" and "notcovered"
which shouldn't happen and is bad. The code that caused this problem last
time appears to have issues where stamps for tasks already exist.

Split out the setscene stamp checking code to a separate function and
use this when checking "hard dependencies" (like pseudo-native) so
that if the stamps exist and it will be "covered", it is not put on
the notcovered list.

5386b3db50 bitbake: runqueue: Print pseudo.log if fakeroot task failed
Currently if pseudo fails we can only see the path to pseudo.log. If we
have no access to server and can only rely on bitbake log then debugging
becomes impossible. This printing needs to be added in runqueue level,
not inside task execution, because in some cases task fails with pseudo
abort really early and we don't even see any log.

In this change I'm adding pseudo log printing in every fakeroot task
failure that logged `mismatch`, `error` or `fatal` to logfile, because
we have no other way to communicate with pseudo if it failed or not.
Only lines from last pseudo server execution will be printed.

341208aa87 bitbake: runqueue: Fix task execution corruption issue
We've seen occasional issues where linux-yocto:do_compile_kernelmodules would
run without do_shared_workdir running before it. do_shared_workdir is an
setscene task but never has an sstate object generated so it will always
rerun. This should not happen since compile_kernemodules should only
execute if a setscene that depends on it didn't run and that should trigger
do_shared_workdir not to be marked as covered.

The issue is that build-appliance-image:do_package is one of the tasks which
covers linux-yocto:do_compile_kernelmodules but it is also a noexec task
and has a dependecy on pseudo-native:do_populate_sysroot.

In the problem case, pseudo-native:do_populate_sysroot is unavailable but
marked as covered since it is noexec. The "harddeps" code then also marks it
as notcovered. No task should ever be both covered and notcovered and this
is where the problems come from.

The solution is for the harddeps code only to to fail tasks if they've not
already been handled in some way. The code is assuming code couldn't have
handled revdeps at this point but we now have clear evidence they can.

8b792d4f75 bitbake: event: Prevent bitbake from executing event handler for wrong multiconfig target
When multiconfig is used bitbake might try to run events that don't
exist for specific mc target. In cooker.py we pass
`self.databuilder.mcdata[mc]` data that contains names of events'
handlers per mc target, but fire_class_handlers uses global _handlers
variable that is created during parsing of all the targets.

This leads to a problem where bitbake runs event handler that don't
exist for a target or even overrides them - if multiple targets use
event handler with the same name but different code then only one
version will be executed for all targets.

See [YOCTO #13071] for detailed bug information.

Add mc target name as a prefix to event handler name so there won't be
two different handlers with the same name. Add internal __BBHANDLERS_MC
variable to have the handlers lists per machine.

75f87db413 bitbake: logging: Make bitbake logger compatible with python logger
The bitbake logger overrode the definition of the debug() logging call
to include a debug level, but this causes problems with code that may
be using standard python logging, since the extra argument is
interpreted differently.

Instead, change the bitbake loggers debug() call to match the python
logger call and add a debug2() and debug3() API to replace calls that
were logging to a different debug level.

118f009cee bitbake: runqueue: Avoid unpickle errors in rare cases
In rare cases the pickled data from a task contains "</event>" which
causes backtrace. This can be reproduced with something like:

do_unpack_prepend () {
    bb.warn("</event>")
}

There are several solutions but the easiest is to catch this exception
and look for the next marker instead as this should be the only way such
an unpickle error could occur.

This fixes rare exceptions seen on the autobuilder.

Also add in other potential exceptions listed in the pickle manual
page so that better debug is obtained should there be an error in
this code path in future. exitcode doesn't need the same handling
since we control what is in that data field and it could never contain
</exitcode>

Passing all the data caches to the task hashing functions allows them to
correctly account for mcdepends in task signatures. This allows tasks to
be correctly re-run when a mcdepends changes.

By default, the legacy behavior is maintained for derived signature
generators by passing a special proxy object that can either be used to
access all multiconfigs or the legacy behavior. If a derived signature
generator is updated, it can set the supports_multiconfig_datacaces
property to instruct bitbake it deals with multiconfigs properly.
