bitbake: runqueue.py: revised completion scheduler

2017-01-20T11:52:52+00:00

The idea is that tasks which complete building a recipe (like do_package_qa) are more important than tasks which start building new recipes (do_fetch) or those which increase disk usage (do_compile). Therefore tasks get ordered like this (most important first, do_rm_work before do_build because the enhanced rm_work.bbclass was used): 1.

The order of the same task between different recipes is the same as with the speed scheduler, i.e. more important recipes come first.

bitbake: runqueue: Fix traceback when using -b

2017-01-20T11:52:52+00:00

Without this, bitbake -b of image recipes cause tracebacks since the list of providers is empty. (Bitbake rev: c53e43f3c6a675c0934a7a4e358fd66b049ffca3) Signed-off-by: Richard Purdie

bitbake: use multiple processes to dump signatures.

2017-01-17T11:29:28+00:00

This change significantly shortens the time on reparsing stage of '-S' option. Each file is reparsed and then dumped within a dedicated process. The maximum number of the running processes is not greater than the value of BB_NUMBER_PARSE_THREADS if it is set. The dump_sigs() in class SignatureGeneratorBasic is _replaced_ by a new dump_sigfn() interface, so calls from the outside and subclasses are dispatched to the implementation in the base class of SignatureGeneratorBasic.

bitbake: runqueue: Only start fakeroot workers when needed

2016-12-22T12:36:40+00:00

Fakeroot workers usually have dependencies that need to be ready before they can be started. Starting them as a block therefore doesn't work as the dependencies may or may not have been built. Therefore start the multiconfig fakeworkers individually upon demand. [YOCTO #10344] (Bitbake rev: ab15486c636e451ed5a62e561980946887901c3b) Signed-off-by: Richard Purdie

bitbake: runqueue: Ensure setscene tasks with overlapping stamps don't parallel execute

2016-12-22T12:36:40+00:00

In multiconfig, mutliple tasks can execute which share the same stamp file. These must not execute in parallel, the idea is the first should execute, the subsequent ones should see a valid stamp and get skipped. The normal task execution code has stamps code to handle this, this adds similar code to the setscene execute() function to handle the issue there too.

bitbake: runqueue: Fix setscene issues with multiconfig

2016-12-22T12:36:40+00:00

setscene was being entirelu skipped for multiconfig variants as the tasks were simply not being spotted. If the default config was also being built it masked the problem. When this was fixed by using taskfn instead of fn in lookups against dataCache, several other instances of this problem were highlighted. This goes through and corrects the setscene code to correclty use taskfn instead of fn in the appropriate places meaning setscene tasks for multiconfig now work correctly.

bitbake: runqueue: Ensure pseudo executes from the correct place (use the right datastore with multiconfig)

2016-12-22T12:36:40+00:00

The location of the fakeroot command and the various environmental values need to be taken from the right multiconfig datastore, not the shared one. This patch ensures the right one is used for cases like a split TMPDIR. [YOCTO #10344] (Bitbake rev: 813a7600bc26b7132ac36d1515571d321f566afb) Signed-off-by: Richard Purdie

bitbake: runqueue: dry-run real tasks when BB_SETSCENE_ENFORCE is set

2016-12-20T15:22:50+00:00

For the purposes BB_SETSCENE_ENFORCE is designed for (in OE, it is used by the installation process for the extensible SDK), we don't actually need the whitelisted real tasks to execute - we just need to have them in the dependency tree so that we get all of the setscene tasks they depend on to run. Therefore we can actually dry-run those real tasks i.e. they won't be run (and thus we won't waste a significant amount of time doing so) and won't be stamped as having run either. We do already have a dry-run mode in BitBake (activated by the -n or --dry-run command line option), but it dry-runs the setscene tasks as well which we don't want here. Note that this has no effect on the checking we are doing with BB_SETSCENE_ENFORCE to ensure that only whitelisted real tasks are scheduled to run - that's handled separately. Fixes [YOCTO #10369].

bitbake: cooker/command: Drop expanded_data

2016-12-16T10:23:24+00:00

Some of our metadata assumes that BuildStarted and BuildCompleted events see the same data store. This is the case for buildTarget but not for buildFile and recent changes mean this is now a problem. The update_data() call is now an empty operation and there is no difference between the expanded_data and data so we can simply remove the expanded_data and its references and use data everywhere. This has been inteded for a while but the above issue makes this more pressing to finally clean up. (Bitbake rev: e3694e738e98f26f413ada6860ca7d829d3662f0) Signed-off-by: Richard Purdie

bitbake: runqueue: enable setVariable command to affect task execution

2016-12-14T12:25:07+00:00

Allow the client to set variables with the setVariable command and have those changes take effect when running tasks. This is accomplished by collecting changes made by setVariable separately and pass these to the worker so it can be applied on top of the datastore it creates.
