bitbake: event/ast: Add RecipeTaskPreProcess event before task finalisation

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

There are various pieces of code which need to run after the tasks are finalised but before bitbake locks in on the task dependencies. This adds such an event so dependency changes in anonymous python can be accounted for and acted upon by these specific event handlers.

bitbake: event: Replace slightly elderly bbmake references!

2017-01-09T13:39:13+00:00

bbmake hasn't existed for a while (a decade+) so we should probably remove the references. (Bitbake rev: 4170cf874850b950f31d2e36c895c110c0b096c3) Signed-off-by: Richard Purdie

bitbake: monitordisk: add event

2016-12-07T10:42:22+00:00

The current disk usage is interesting and may be worth logging over time as part of the build statistics. Instead of re-implementing the code and the configuration option (BB_DISKMON_DIRS), the information gathered by monitordisk.py is made available to buildstats.bbclass via a new event. This has pros and cons: - there is already a useful default configuration for "interesting" directories - no code duplication - on the other hand, users cannot configure recording separately from monitoring (probably not that important) (Bitbake rev: f065ac17d0031dca6309ddbff18c8792630de865) Signed-off-by: Patrick Ohly Signed-off-by: Richard Purdie

bitbake: cooker process: fire heartbeat event at regular time intervals

2016-12-07T10:42:22+00:00

The intended usage is for recording current system statistics from /proc in buildstats.bbclass during a build and for improving the BB_DISKMON_DIRS implementation. All other existing hooks are less suitable because they trigger at unpredictable rates: too often can be handled by doing rate-limiting in the event handler, but not often enough (for example, when there is only one long-running task) cannot because the handler does not get called at all. The implementation of the new heartbeat event hooks into the cooker process event queue. The process already wakes up every 0.1s, which is often enough for the intentionally coarse 1s delay between heartbeats. That value was chosen to keep the overhead low while still being frequent enough for the intended usage. If necessary, BB_HEARTBEAT_EVENT can be set to a float specifying the delay in seconds between these heartbeat events.

bitbake: bb.event: fix infinite loop on print_ui_queue

2016-10-15T09:01:44+00:00

If bitbake ends before _uiready and bb.event.LogHandler was add to the bitbake logger it causes an infinite loop when logging something. The scenario is print_ui_queue is called at exit and executes the log handlers [2] one of them is bb.event.LogHandler this handler appends the same entry to ui_queue causing the inifine loop [3]. In order to fix a new copy of the ui_queue list is created when iterate ui_queue.

bitbake: event: prevent unclosed file warning in print_ui_queue

2016-10-05T09:25:34+00:00

Use logger.addHandler(), rather than assigning an array of Handlers to the loggers handlers property directly, to avoid a warning from Python 3 about unclosed files: $ bitbake Nothing to do. Use 'bitbake world' to build everything, or run 'bitbake --help' for usage information.

bitbake: bb/event.py: fire_ui_handlers enable threading lock support

2016-10-05T09:10:11+00:00

In some cases there is a need to fire bb events into multiple python threads so locking is needed (writing to a fd/socket). Adding a helper functions for disable/enable by request to avoid overhead.

bitbake: event.py: output errors and warnings to stderr

2016-09-15T11:15:07+00:00

All logging messages are printed on stdout when processing UI event queue. This makes it impossible to distinguish between errors and normal bitbake output. Output to stderror or stdout depending on log level should fix this. (Bitbake rev: 56ac0d4c7a5f47aeb707b15a0c305d9f73aae945) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

bitbake: cooker: add BuildInit event

2016-08-10T23:09:26+00:00

In situations where a bitbake run fails before the build properly starts and BuildStarted is fired, a UI has no way to get at the targets passed to the build. This makes it difficult for the UI to report on the targets which failed. Fire a BuildInit event before running buildTargets() or buildFile(). This enables a UI to capture targets passed to buildTargets(), even if the build fails (e.g. the targets themselves are invalid).
