bitbake: bitbake: Share BB_TASKDEPDATA with tasks

2013-11-26T23:01:33+00:00

Currently tasks have no knowledge of which other tasks they depend upon. This makes it impossible to do at least two things which would be desirable/interesting: a) Have the ability to create per recipe sysroots b) Allow the aclocal files to be present only for the entries in DEPENDS (directly and indirectly) By exporting task data through this new variable, tasks can inspect their dependencies and then take actions based upon this.

bitbake: runqueue: Optimise next_buildable_task()

2013-11-26T23:01:33+00:00

This unlikely looking function was found to be eating a lot of CPU time since it gets called once per trip through the idle loop if we're not running a maximum number of processes. This was particularly true in world builds of 13,000 tasks. Calling the computation code is pretty pointless because until some other task finishes nothing is going to become available to build. We can know when things become available so this patch teaches the scheduler this knowledge. It also: * skips any coputation when nothing can be built * if there is only one available item to build, ignore the priority map * precomputes the stamp filenames, rather than doing it every time * saves the length of the array rather than calculating it each time (the extra function overhead is significant) Timing wise, initially, 5000 iterations through here was 20s, with the patch 200000 calls takes the same time. The end result is that builds get up and running faster. (Bitbake rev: 4841c1d37c503a366f99e3a134dca7440e3a08ea) Signed-off-by: Richard Purdie

bitbake: runqueue/bitbake-worker: Fix dry run fakeroot issues

2013-11-24T12:25:36+00:00

When using the dry run option (-n), bitbake would still try and fire a specific fakeroot worker. This is doomed to failure since it might well not have been built. Add in some checks to prevent the failures. [YOCTO #5367] (Bitbake rev: f34d0606f87ce9dacadeb78bac35879b74f10559) Signed-off-by: Richard Purdie

bitbake: runqueue: Fix hole in setsceneverify skipped task logic

2013-11-20T13:48:01+00:00

We have do_bundle_initramfs which is a task inserted after compile and before build. It is not covered by sstate. If we run a build with a valid sstate cache present, the setsceneverify function realises it will rerun the do_compile step (due to the bundle_initramfs task) and hence marks do_populate_sysroot to rerun. do_install, a dependency of do_populate_sysroot is left as marked as covered by sstate. What we need to do is traverse the dependency tree for any setsceneverify invalided task and ensure any dependencies are also invalidated. We can stop at any point we reach another setscene task though. This means the do_populate_sysroot task has the data from do_install available and doesn't crash.

bitbake: bitbake: runqueue: add task hash to Queue events

2013-09-22T11:19:44+00:00

Adding the sstate-related hash for all runqueue and scenequeue tasks, as it's needed in the WebHob data. (Bitbake rev: b6e2ce1cf7a0ede890f08fabf536a556dc4263c5) Signed-off-by: Alexandru DAMIAN Signed-off-by: Richard Purdie

bitbake: bitbake: build, runqueue: adds info to the runQueue events

2013-09-22T11:19:44+00:00

This patch adds task identifying information for all runQueue and sceneQueue events, and for bb.build.Task* events. This will allow matching event to specific tasks in the UI handlers processing these events. Adds RunQueueData functions to get the task name and task file for usage with the runQueue* events. Adds taskfile and taskname properties to bb.build.TaskBase. Adds taskfile and taskname properties to the *runQueue* events (Bitbake rev: b4a5e4be50d871a80dbe0993117d73f5ad82e38f) Signed-off-by: Alexandru DAMIAN Signed-off-by: Richard Purdie

bitbake: bitbake: cooker,runqueue: send the task dependency tree

2013-09-22T11:19:43+00:00

Adding a CookerFeature that allows UIs to enable receving a dependency tree once the task data has been computed and the runQueue is ready to start. This will allow the clients to display dependency data in an efficient manner, and not recompute the runqueue specifically to get the dependency data.

bitbake: runqueue: add runQueueTaskSkipped event

2013-09-17T13:11:02+00:00

Adding a runQueueTaskSkipped to notify that the tasks that are not run either because they are set-scened or they don't need an update (timestamp was ok). (Bitbake rev: cf4a0c7aa82090876ae652b611acfab3ce2688f7) Signed-off-by: Richard Purdie

bitbake: bitbake: runqueue: add sceneQueueTaskCompleted event

2013-09-10T14:57:20+00:00

Adding an event to be fired when a scene task is completed. It is analogous to the run task completed event, and has been missing for some reason. (Bitbake rev: 73b8f4d3fbeaf1b330a66d76012d0a5cef8dbe2d) Signed-off-by: Alexandru DAMIAN Signed-off-by: Richard Purdie

bitbake: runqueue.py: check whether multiple versions of the same PN are due to be built

2013-09-09T15:28:46+00:00

There would be an race issue if we: $ bitbake make-3.81 make-3.82 This because they are being built at the same time which would cause unexpected problems, for example: [snip] ERROR: Package already staged (/path/to/tmp/sstate-control/manifest-qemux86-make.populate-sysroot)?! ERROR: Function failed: sstate_task_postfunc [snip] Or there would be python's strack trace such as: [snip] *** 0004: mfile = open(manifest) 0005: entries = mfile.readlines() 0006: mfile.close() 0007: 0008: for entry in entries: Exception: IOError: [Errno 2] No such file or directory: xxx [snip] [YOCTO #5094] We can quit earlier to avoid this kind of issue when two versions of the same PN are going to be built since this isn't supported.
