* bitbake: runqueue: improve exception loggingEd Bartosh2016-07-191-2/+2
| | | | | | | | | | | | | | | Runqueue errors direct the user to view the "failure below", but no additional error message is available. Log the stacktrace so that the user can see what went wrong. Also fix a typo in the log message.

* bitbake: runqueue: report progress for "Preparing RunQueue" stepPaul Eggleton2016-07-081-3/+67
| | | | | | | | | | | | | | | | | | | | | When "Preparing RunQueue" shows up you can expect to wait up to 30 seconds while it works - which is a bit long to leave the user waiting without any kind of output. Since the work being carried out during this time is divided into stages such that it's practical to determine internally how it's progressing, replace the message with a progress bar. Actually what happens during this time is two major steps rather than just one - the runqueue preparation itself, followed by the initialisation prior to running setscene tasks. I elected to have the progress bar cover both as one (there doesn't appear to be much point in doing otherwise from a user perspective). I did however describe it as "initialising tasks".

* bitbake: runqueue: add ability to enforce that tasks are setscenedPaul Eggleton2016-07-081-1/+80
| | | | | | | | | | | | | | | | | | | | | | | | Add the ability to enter a mode where only a specified whitelist of tasks can be executed outright; everything else must be successfully provided in the form of a setscene task (or covered by a setscene task). Any setscene failure outside of the whitelist will cause the build to fail immediately instead of running the real task, and any real tasks that would execute outside of the whitelist cause an immediate build failure when it comes to executing the runqueue as well. The mode is enabled by setting BB_SETSCENE_ENFORCE="1", and the whitelist is specified through BB_SETSCENE_ENFORCE_WHITELIST, consisting of pn:taskname pairs. A single % character can be substituted for the pn value to match any target explicitly specified on the bitbake command line. Wildcards * and ? can also be used as per standard unix file name matching for both pn and taskname. Part of the implementation of [YOCTO #9367].

* bitbake: taskdata/runqueue: Rewrite without use of ID indirectionRichard Purdie2016-06-151-500/+458
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm not sure what possesed me when I wrote this code originally but its indirection of everyting to use numeric IDs and position dependent lists is horrific. Given the way python internals work, its completely and utterly pointless from performance perspective. It also makes the code hard to understand and debug since any numeric ID has to be translated into something human readable. The hard part is that the IDs are infectous and spread from taskdata into runqueue and even partly into cooker for the dependency graph processing. The only real way to deal with this is to convert everything to use a more sane data structure. This patch: * Uses "<fn>:<taskname>" as the ID for tasks rather than a number * Changes to dict() based structures rather than position dependent lists * Drops the build name, runtime name and filename ID indexes On the most part there shouldn't be user visible changes. Sadly we did leak datastructures to the setscene verify function which has to be rewritten. To handle this, the variable name used to specifiy the version changes from BB_SETSCENE_VERIFY_FUNCTION to BB_SETSCENE_VERIFY_FUNCTION2 allowing multiple versions of bitbake to work with suitably written metadata. Anyone with custom schedulers may also need to change them. I believe the benefits in code readability and easier debugging far outweigh those issues though. It also means we have a saner codebase to add multiconfig support on top of. During development, I did have some of the original code coexisting with the new data stores to allow comparision of the data and check it was working correcty, particuarly for taskdata. I have also compared task-depends.dot files before and after the change. There should be no functionality changes in this patch, its purely a data structure change and that is visible in the patch.

* bitbake: runqueue: Change buildable/running lists to setsRichard Purdie2016-06-151-36/+27
| | | | | | | | | | | | | | Using positions in lists for flags is an odd choice and makes the code hard to maintain. Maintaining a list is slow since list searches are slow (watch bitbake -n slow massively with it) but we can use a set() instead. This patch uses python sets to maintain the lists of tasks in each state and this prepares for changing the task IDs from being integers.

* bitbake: runqueue.py: always emit bb.event.DepTreeGeneratedPatrick Ohly2016-05-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | The data included in the event is useful for implementing a pre-build check that warns about unexpected components, for example because of an incorrect configuration or changed dependencies. Such a check can be done in a .bbclass that gets inherited globally. But in contrast to a UI, such a class cannot request that the event shall be emitted, and thus the event has to be emitted whether there is a consumer or not. This was done conditionally earlier out of concerns about the performance impact. But now events are handled more efficiently, so that concern no longer seems valid: in some simple testing (admittedly on a fast build workstation), the two lines (generating the data and emitting the event with it) only took about 0.05 seconds (measured with timeit). That was for a build with roughly 500 recipes (from pn-buildlist aka depgraph['pn']), triggered via the command line. That was even with a consumer of the data active and doing some work, so it should be even faster when there is no consumer.

* bitbake: runqueue: Improve 'mulitiple .bb files are due to be built' messageRichard Purdie2016-04-121-2/+70
| | | | | | | | | | | | | | | | | | | | | | | | | When multiple recipes which both provide something are being built, bitbake informs us that most likely one of them provides something the other doesn't, which is usually correct, but unfortunately it's rather painful to figure out exactly what that is. This patch dumps two sets of information, one is the provides information for each recipe, filtered so only common components are removed. The other is a list of dependees on the recipe, since sometimes this can easily identify why something is being built. Its not straightforward for bitbake to obtain the information but since the warning/error code path isn't the normal one, we can afford to go through some less than optimal processing to aid debugging. Also provide the same information even if we're showing a warning since its still useful.

* bitbake: Revert "runqueue.py: Ensure one setscene function doesn't mask out ↵Richard Purdie2016-01-191-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | another which needs to run" This reverts commit b22592af8145a8c7c4ada2fa7c1dee2e753eca46. That commit isn't entirely clear about why this change is needed but I do have a usecase where this breaks things. If for example you run "bitbake X -c packagedata" and that packagedata is in sstate, you'd expect this to work. If sstate doesn't contain a do_populate_sysroot for a dependency, you would still expect the command above to succeed and you would not expect it to rebuild that dependency. With the current code, this isn't what happens. The code finds the sstate for do_populate_sysroot missing, this makes the task "uncovered" and this in turn makes it unskippable. The example I found with this was avahi-ui, where it would trigger a build of libdaemon to obtain its populate_sysroot. Since this behaviour seems completely incorrect, revert the older patch and we'll address any issues that crop up as a result.

* bitbake: runqueue: Fix setscene task dependenciesRichard Purdie2016-01-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Debugging suggests that setscene tasks are being a little greedy about their dependencies, for example, lsof is insisting that gcc-runtime's do_package is installed. If it isn't, its requiring gcc to rebuild. If gcc-runtime do_package_write_xxx and do_packagedata is available, there is no reason do_package should be needed. The reason this is happening appears to be from the batching up of task dependencies code, rather than setscene tasks stopping when passing over a setscene task, they were being carried forward. This patch fixes it so the data is 'zeroed' when passing over a setscene task boundary, which gives the dependency graph that is expected. After this patch, lsof will rebuild quite happily without gcc-runtime:do_package being present, as expected. This should lead to less dependencies being installed for builds from sstate and generally better performance in general.

The reason for this was the default task weights of 0 being to tasks. This is therefore changed to 1 to allow correct weighting of dependencies which means the scheduler has better information available to it about tasks. Weight endpoints differently (10) for clearer debugging of priorities. (Bitbake rev: 12dc1d17fac3e8ec420fcafb06186d32fd847d89) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* bitbake: runqueue: Fix handling of zero priority taskRichard Purdie2014-04-231-1/+1
| | | | | | | | | | | | | The zero priority task should be run first but was being confused with the None value the priority field defaulted to. Check for None explicitly to avoid this error. In the real world this doesn't change much but it confused the debug output from the schedulers.

* bitbake: runqueue: Address issues with incomplete sstate setsRichard Purdie2014-04-011-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first part of the sstate code checks en-mass whether given checksums are available. The next part of the code then either triggers those setscene tasks either running them or skipping them if they've been covered by others. The problems was that this second part would always skip a task if it was unavailable in the first part, even if it would have otherwise been covered by other tasks. This mean the mere presence of an artefact (or lack of presence) could cause a different build failure. The issue reproduces if you run a build and populate an sstate feed, then run a second build off that feed, then run a third build off the sstate feed of the second build (which is reduced in size). The fix is rather than immediately skipping tasks if the checksum is unavailable, create a list of missing tasks, then, if that task cannot be covered by others we can skip it later. The deferral makes the behaviour the same even when the cache is "incomplete".

* bitbake: runqueue: Fix sstate task dependency problemsRichard Purdie2014-04-011-0/+4
| | | | | | | | | | | | | If a setscene task has [depends], its possible they may still get executed out of order. The issue is that the dependencies are set to set() for all tasks involved. This patch adds back in explict dependencies within these chains to avoid the setscene task failures.

* bitbake: bitbake: Force -S option to take a parameterRichard Purdie2014-03-271-3/+6
| | | | | | | | | | | | | There is no easy way to make this change. We really need parameters for the -S (dump signatures) handling code. Such a parameter can then be used within the codebase to handle the signatures in different ways. For now, "none" is the recommended default and "printdiff" will execute the new (and more expensive) comparison algorithms.

* bitbake: runqueue: Remove use of waitpid on worker processesRichard Purdie2014-03-191-16/+12
| | | | | | | | | | | | | Use of waitpid on the worker processes is a bad idea since it conflicts directly with subprocess internals. Instead use the poll() method and returncode to determine if the process has exitted, if it has, we can shut down the system. This should resolve the hangs once and for all, famous last words.

* bitbake: runqueue: Revert child signal handler for nowRichard Purdie2014-03-191-28/+17
| | | | | | | | | | | | | | | | | | | | | | | | | We're running into processes using 100% cpu. It appears theses are locked in a subprocess.poll() type loop where the process has exited but the code is looping as its not handling the ECHILD error. http://bugs.python.org/issue14396 http://bugs.python.org/issue15756 This is likely due to one or both of the above bugs. The question is what actually grabbed the child exit code as it wasn't this code. Its likely there is therefore some other code racing and taking that code, it may be some kind of race like: http://hg.python.org/cpython/rev/767420808a62/ where the fix effectively catches the childs codes in a different part of the system. We could try and get everyone onto python 2.7.4 where the above bugs are fixed however for now its safer to admit defeat and go back to polling explictly for our worker exit codes.

* bitbake: runqueue: Really fix sigchld handlingRichard Purdie2014-03-181-14/+14
| | | | | | | | | | | | | | | | | | | There are several problems. Firstly, a return value of "None" can mean there is a C signal handler installed so we need to better handle that case. signal.SIG_DFL is 0 which equates to false so we also need to handle that by testing explicitly for None. Finally, the signal handler *must* call waitpid on all child processes else it will just get called repeatedly, leading to the hanging behaviour we've been seeing. The solution is to only error for the worker children, we warn about any other stray children which we'll have to figure out the sources of in due course. Hopefully this patch gets things working again properly though. (Bitbake rev: 973876c706f08735c1b68c791a5a137e5f083dd2) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* bitbake: runqueue: More carefully handle the sigchld handlerRichard Purdie2014-03-181-2/+4
| | | | | | | | | | | | We've noticed hanging processes which appear to be looping around waitpid. Its possible multiple calls to teardown are causing problem or in theory multiple registrations (although the code should not allow that). Regardless, put better guards around signal handler registration. (Bitbake rev: 79acfb0853aa3215215cee89a945f8e97b0a8fae) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
