Re: CI-Scripts and RTEMS Cached files on GHA

[Ralph Lange via Core-talk <core-talk at aps.anl.gov>]

Hi Andrew,

The node version changes are unrelated.

The GHA cache is set up to only cache our dependency modules, not the RTEMS chain (in /opt/rtems/...) that the failing build is missing.

The key difference is that a successful build installs the RTEMS environment:

While the failing build does not.

Any build that finds a vaild cache for Base fails, since the part of the ci-scripts that downloads and installs the RTEMS chain is not run.

If you look at the build history, the working builds are those that did not find a valid cache.

To state the obvious: When using caches, everything that is being generated or downloaded as part of the job must be in the cache.

Cheers,

~Ralph

Earlier today I had to clear the cached copies of the dependencies for the 3 RTEMS builds of pvAccessCPP. Looking at this run, despite apparently successfully restoring the cached copies:

the main builds were failing with this error:

I am also seeing these "Annotations" about the run from GHA which I suspect may be related:

 

7.0 Ub-20 gcc-9 + RT-5.1 pc686

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v2, actions/cache@v2, actions/upload-artifact@v2. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

Show less

7.0 Ub-20 gcc-9 + RT-5.1 pc686

The following actions uses node12 which is deprecated and will be forced to run on node16: actions/checkout@v2, actions/cache@v2, actions/upload-artifact@v2. For more info: https://github.blog/changelog/2023-06-13-github-actions-all-actions-will-run-on-node16-instead-of-node12-by-default/

 

On deleting the cached data the dependencies are rebuilt and the main build succeeds (see run #70), but it fails again on subsequent builds (#71). I just cleared the caches again and re-ran the failed builds which I hope will succeed.

 

Can anyone explain what needs to be done to fix this properly?

 

Thanks,
