Re: [Buildroot] [PATCH v2 RFC] support/scripts: don't build board defconfigs with Gitlab's pipelines trigged on tag

["Yann E. MORIN" <yann.morin.1998@free.fr>]

Romain, All,

+Arnout

On 2021-11-09 23:03 +0100, Romain Naour spake thusly:
> Currently when a tag is added to the Buildroot git tree, the gitlab-ci
> create a pipeline with several hundred of jobs (~750) to build all
> defconfigs and execute the Buildroot testsuite.
> 
> However, there is only a limited number of gitlab-ci runner (9 runners)
> and some jobs reach the timeout limit (24h) while waiting for a runner
> [1]. Indeed, the Buildroot project doesn't use the Gitlab's shared
> runners.
> 
> In addition to the pipeline created when a new tag is added to the
> git repository, two pipelines are created each weeks to execute the
> Buildroot testsuite (on monday [2]) and build all defconfigs (on
> Thursday [3]).
> 
> At some point there are too many jobs waiting in gitlab due board
> defconfigs builds. Indded a board defconfig requires a lot of time
> (~30min) compared to other jobs in order to build a toolchain and a
> kernel linux along with a basic rootfs. There is currently 262
> defconfigs.
> 
> This is even worse when several pipelines are trigged at the same
> time (new git tag and scheduled pipeline trigger).
> 
> In order to reduce the number of long jobs, don't build board
> defconfigs with pipelines trigged on tag, keeping only the runtime
> tests and the Qemu's defconfigs.

If noone whines shortly, I'll apply it.
