rm_work.bbclass: clean up sooner

2017-01-20T11:53:49+00:00

Having do_rm_work depend on do_build had one major disadvantage: do_build depends on the do_build of other recipes, to ensure that runtime dependencies also get built. The effect is that when work on a recipe is complete and it could get cleaned up, do_rm_work still doesn't run because it waits for those other recipes, thus leading to more temporary disk space usage than really needed. The right solution is to inject do_rm_work before do_build and after all tasks of the recipe. Achieving that depends on the new bitbake bb.event.RecipeTaskPreProcess and bb.build.preceedtask(). It can't just run in an anonymous function, because other anonymous functions that run later may add more tasks. There's still such a potential conflict when some future RecipeTaskPreProcess event handler also wants to change task dependencies, but that's not a problem now. Should it ever occur, the two handlers will have to know about each other and cooperate to resolve the conflict. Benchmarking (see "rm_work + pybootchart enhancements" on the OE-core mailing list) showed that builds with the modified rm_work.bbclass were both faster (albeit not by much) and required considerably less disk space (14230MiB instead of 18740MiB for core-image-sato). Interestingly enough, builds with rm_work.bbclass were also faster than those without.

rm_work.bbclass: allow preserving additional content

2017-01-20T11:53:48+00:00

By default, do_rm_work either skips recipes entirely (when listed in RM_WORK_EXCLUDE) or removes everything except for temp. In meta-swupd, virtual image recipes collaborate on producing update data for the base recipe. Tasks running in the base recipe need some information from the virtual images. Those files could be passed via a new shared work directory, but that scatters data in even more places. It's simpler to use the normal WORKDIR and teach rm_work.bbclass to not remove the special output with the new RM_WORK_EXCLUDE_ITEMS.

meta: remove True option to getVar calls

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

getVar() now defaults to expanding by default, thus remove the True option from getVar() calls with a regex search and replace. Search made with the following regex: getVar ?\(( ?[^,()]*), True\) (From OE-Core rev: 7c552996597faaee2fbee185b250c0ee30ea3b5f) Signed-off-by: Joshua Lock Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

rm_work: add do_write_qemuboot_conf to task list

2016-12-13T22:55:20+00:00

We need to add do_write_qemuboot_conf to the list of tasks to be wiped as otherwise the second time an image is built it will fail. [ YOCTO #10758 ] (From OE-Core rev: 3206f408e908870629eb47afac6249a3c9497a66) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

rm_work: Ensure we don't remove sigbasedata files

2016-11-04T12:50:55+00:00

We don't remove sigdata files, we also shouldn't remove sigbasedata files as this hinders debugging. (From OE-Core rev: 988349f90c8dc5498b1f08f71e99b13e928a0fd0) Signed-off-by: Richard Purdie

rm_work: don't remove timestamps of image tasks

2016-08-23T16:44:41+00:00

Excluded removal of do_bootimg, do_bootdirectdisk and do_vmimg timestamps to prevent unneeded rootfs rebuilds. [YOCTO #10159] (From OE-Core rev: f214da502ad7eda27460dc6f06e9cd29a114f2d2) Signed-off-by: Ed Bartosh Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

classes/rm_work: use the idle I/O scheduler class

2016-06-15T17:05:22+00:00

As rm_work is just cleanup it shouldn't starve more important tasks such as do_compile of I/O, so use BB_TASK_IONICE_LEVEL to run the task in the idle scheduler class. (From OE-Core rev: 6025a14dbbd09b2805fe2e17ddc24f2a515cb832) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

classes: Fix do_rootfs references

2016-01-11T23:26:29+00:00

After the separation of do_rootfs, some rootfs references need changing to image_complete. (From OE-Core rev: 59a5f596ca29b1eb8283706e3c60fbb39f9c2c23) Signed-off-by: Richard Purdie

2015-11-16T11:39:33+00:00

This prevents unneeded rootfs rebuilds if the metadata has not changed while using rm_work. (From OE-Core rev: 7550b13786caa68a9944cd802eb970acbd17e754) Signed-off-by: Jate Sujjavanich Signed-off-by: Ross Burton Signed-off-by: Richard Purdie
