bitbake: runqueue: fix PSI check calculation

2023-04-22T09:30:42+00:00

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.

bitbake: event/cooker/runqueue: Add ability to interrupt longer running code

2023-02-23T12:12:18+00:00

Bitbake is now able to understand when a UI wants it to stop the current processing. There are some long running functions which currently have no mechanism to interrupt them however. This patch adds a call, bb.event.check_for_interrupts(d) which can be placed in long running code and allows an internal state flag within bitbake to be checked. If set, that flag will trigger an exit. This means that Ctrl+C can be made to work in a variety of places where it currently would not. Long running event handlers in OE-Core can also then benefit from this new approach with the addition of the function call as well.

bitbake: runqueue: Drop SystemExit usage

2023-02-19T07:48:28+00:00

Using bb.fatal for a fatal error message is the best practise, switch the code to match other call sites. (Bitbake rev: c27e48fa81c2327a4a355a028884ab457cde3ae7) Signed-off-by: Richard Purdie

bitbake: event: builtins fix for 'd' deletion

2022-12-29T00:07:06+00:00

I've been seeing event handlers where 'd' seems to disappear half way through event handler execution. This is problematic when multiple threads are active since this code assumes single threading. The easiest fix is to change the handler function calls to contain d as a parameter as we do elsewhere for other functions. This will break any non-text handlers but I was only able to spot one of those in runqueue. It will also break handlers than call functions that assume 'd' is in the global namespace but those failures should be obvious and we can fix those to pass d around. This solution avoids manipulating builtins which was always a horrible thing to do anyway and solves the issue without needing locking, thankfully.

bitbake: build/siggen: Rework stamps functions

2022-12-17T08:52:28+00:00

The current method of passing either a task's datastore, or dataCaches and a filename into the stamp functions is rather horrible. Due to the different contexts, fixing this is hard but we do control the bitbake side of the API usage so we can migrate those to use other functions and then only support a datastore in the public bb.build API which is only called from task context in OE-Core.

bitbake: bitbake: siggen/runqueue: Switch to using RECIPE_SIGGEN_INFO feature for signature dumping

2022-12-17T08:52:28+00:00

Now that we have cache support for the taskdep/gendep/lookupcache data, we can switch to use that cooker feature and skip the secondary reparse to write the sig files. This does make the initial parse longer but means the secondary one isn't needed. At present parsing with the larger cache isn't optimal but we have plans in place which will make this faster than the current reparse code being removed here.

bitbake: siggen: Directly store datacaches reference

2022-12-17T08:52:28+00:00

It is becomming clear the siggen needs access to our cache data but we can't always obtain it in the contexts we need to. Add it directly, meaning over time we should be able to simplify the APIs and stop convoluting new ones! (Bitbake rev: 6b213590ed0e77683cf7fbce6bbe9605ddecf3d3) Signed-off-by: Richard Purdie

bitbake: build/siggen/runqueue: Drop do_setscene references

2022-12-11T23:21:27+00:00

do_setscene was from a different era before our modern setscene per task code. It hasn't been used for years so remove some old obsolete references to it. (Bitbake rev: ef72282298f7c4db74383c23bb0251dd06d3c6d3) Signed-off-by: Richard Purdie

bitbake: siggen: Drop non-multiconfig aware siggen support

2022-12-11T23:21:27+00:00

All siggens in common use should now support multiconfig, drop the compatibility code. (Bitbake rev: b36545b4df6d935ed312ff407d4e0474c3ed8d1a) Signed-off-by: Richard Purdie

bitbake: runqueue: Improve error message for missing multiconfig

2022-11-29T10:25:51+00:00

If you place a multiconfig which isn't enabled into an mcdepends you currently get a traceback from runqueue. We can do better, add some code to tell the user what happened in a more readable way without the traceback.
