Permission denied errors when rebuilding (Python?) bundles with extensions that install binaries #556

bedroge · 2024-04-30T19:01:10Z

When trying to rebuild Python, hatchling, and Python-bundle-PyPI in #546, we ran into weird permission issues for both hatchling and Python-bundle-PyPI. It's not clear yet what's causing it, but it seems to happen for (Python) bundles that include extensions that not only install files to lib, but also to bin.. The removal step seems to work fine and successfully removes the existing installation, but in the build phase the extension will suddenly see the old bin directory again (with read-only permissions), and fail with errors like:

Successfully built hatchling
Installing collected packages: hatchling
ERROR: Could not install packages due to an OSError.
Consider using the `--user` option or check the permissions.

I've tried a lot of possible workarounds in both #546 and #555:

add write permissions (chmod -R u+w) instead of removing the existing installation dir
add write permissions and remove the existing installation dir
also remove the parent dir (e.g. hatchling) instead of only removing the installation dir of the particular version
only remove the contents of the installation dir and not the dir itself
move the existing installation dir instead of removing it
wipe the CVMFS cache between the removal and build steps
use a newer fuse-overlayfs
unsetting EASYBUILD_READ_ONLY_INSTALLDIR before starting the build

None of them solved the issue, though. So, in the end, I opted for working around it by adding write permissions to the affected installation directories on the Stratum 0, and then the rebuilds completed successfully.

The text was updated successfully, but these errors were encountered:

We're now seeing the same issue for our EESSI-extend module (see #578), which is a bundle.

I still don't have a clue why it only happens for some easyconfigs...

bedroge · 2024-10-15T14:31:11Z

Also seeing similar issues for LAMMPS in #788. This one is not a bundle, but a cmakemake easyblock.

== installing...
== ... (took 6 secs)
== FAILED: Installation ended unsuccessfully (build directory: /tmp/bot/easybuild/build/LAMMPS/2Aug2023_update2/foss-2023a-kokkos): build failed (first 300 chars): Failed to remove directory /cvmfs/software.eessi.io/versions/2023.06/software/linux/x86_64/generic/software/LAMMPS/2Aug2023_update2-foss-2023a-kokkos even after 3 attempts.
Reasons: [OSError(39, 'Directory not empty'), OSError(39, 'Directory not empty'), OSError(39, 'Directory not empty')] (took 9 mins 59 secs)

I've debugged this a bit interactively, but still can't find the issue. After the directory gets recreated in the build container, it looks empty at first, but when you do an ls on a file that previously existed, it suddenly shows up... The upper dir looks like this after the directory gets removed:

c---------. 1 bedroge bedroge 0, 0 15 okt 12:53 /tmp/eessi.ugqk5zhaDW/software.eessi.io/overlay-upper/versions/2023.06/software/linux/aarch64/generic/software/LAMMPS/29Aug2024-foss-2023b-kokkos

and like this when it's recreated:

-rwx------. 1 bedroge bedroge    0 15 okt 12:54 .wh..wh..opq

Might also be related to containers/fuse-overlayfs#324?

bedroge · 2024-10-15T14:36:09Z

I've also tried some workarounds here, for instance by explicitly removing every individual file in the installation directory (using find ..... -exec rm ...), as suggested by @casparvl , but that didn't work either.

As an alternative I was thinking of bind mounting a host directory to the installation prefix in the container, but that doesn't seem possible on top of fuse-mounted CVMFS repos. The only way I could make it work is by also bind mounting /cvmfs itself from the host, and then bind mounting an empty host directory on top of it. Though it works, it would mean that we have to assume that /cvmfs is available on the host, which is probably not always true. But perhaps we could still consider implementing this, and only use it in case /cvmfs/software.eessi.io is available on the host. If not, we can fall back to using the fakeroot approach (and hope it works 😅 ). It will make the code in the build script quite complex, though.

boegel · 2024-10-15T14:51:43Z

@bedroge This smells a lot like a bug in fuse-overlayfs, no?

Which version are we using, when have we last tried to update it?

bedroge · 2024-10-15T14:54:48Z

Forgot to mention that, but I also tried using a newer version of fuse-overlayfs (1.14), that didn't help either.

It could be a bug, though we also have a bit of a complex setup here with read-only dirs in a fuse-mounted CVMFS repo, where we delete stuff with fakeroot, and then reuse the upper dir for a fuse-mounted writable overlay on top of it.

bedroge · 2024-10-15T14:55:53Z

And I really don't understand why we only see it sometimes. It worked fine for, for instance, GCC and OpenMPI rebuilds.

boegel · 2024-10-15T15:28:20Z

That complicates making a small reproducer to be able to report this to fuse-overlayfs upstream, of course... :(

Any luck with strace?

bedroge · 2024-10-18T13:43:41Z

Based on @casparvl's suggestion, I've been trying some other workarounds, and at some point it suddenly seemed to work when I removed all files and directories manually and individually. But when I tried to do the same thing with some smart find commands, I couldn't make it work anymore. Even worse, the manual procedure then suddenly didn't seem to work anymore either... After lots of attempt, I think I found out why: it seems to matter what you do in the second container session (i.e. the build step) in a very strange and unexpected way.

So I tried this on the EESSI-extend/2023.06-easybuild installation, which is known to fail for rebuilds.
Removal step, with --fakeroot:

Apptainer> rm -rf /cvmfs/software.eessi.io/versions/2023.06/software/linux/aarch64/generic/software/EESSI-extend/2023.06-easybuild/

Then resume the container without --fakeroot and run:

Apptainer> ls /cvmfs/software.eessi.io/versions/2023.06/software/linux/aarch64/generic/software/EESSI-extend/2023.06-easybuild
Apptainer> ls /cvmfs/software.eessi.io/versions/2023.06/software/linux/aarch64/generic/software/EESSI-extend/2023.06-easybuild/easybuild/
EESSI-extend-2023.06-easybuild-easybuild-devel	easybuild-EESSI-extend-2023.06-20241009.203845.log.bz2	       reprod
EESSI-extend-2023.06-easybuild.eb		easybuild-EESSI-extend-2023.06-20241009.203845_test_report.md

This is the issue that we often see in PRs, where the installation prefix seems empty, but if you know what to look for, files are suddenly still there.

Now I'm redoing the same steps in a clean container, do the removal in the same way, and just do one additional ls in the second step:

Apptainer> mkdir /cvmfs/software.eessi.io/versions/2023.06/software/linux/aarch64/generic/software/EESSI-extend/2023.06-easybuild
Apptainer> ls /cvmfs/software.eessi.io/versions/2023.06/software/linux/aarch64/generic/software/EESSI-extend/2023.06-easybuild/easybuild/
ls: cannot access '/cvmfs/software.eessi.io/versions/2023.06/software/linux/aarch64/generic/software/EESSI-extend/2023.06-easybuild/easybuild/': No such file or directory
Apptainer> ls /cvmfs/software.eessi.io/versions/2023.06/software/linux/aarch64/generic/software/EESSI-extend/2023.06-easybuild
Apptainer> ls /cvmfs/software.eessi.io/versions/2023.06/software/linux/aarch64/generic/software/EESSI-extend/2023.06-easybuild/easybuild/
ls: cannot access '/cvmfs/software.eessi.io/versions/2023.06/software/linux/aarch64/generic/software/EESSI-extend/2023.06-easybuild/easybuild/': No such file or directory

So, the issue only pops up when you first do an ls on the (empty) installation directory itself 🤯 😵‍💫

bedroge · 2024-10-18T15:35:47Z

And though the fix seems easy, it may not be trivial. The affected subdir seems to be different for each installation: sometimes it's easybuild, sometimes it's bin. We could make a dump of all subdirs of the installation prefix before actually removing them, and then do an ls on each of them in the build script, but I really don't like that 😅 I've tried several more simple workarounds, but haven't found any yet. For instance, doing this in the removal container doesn't solve it. It looks like it's solved, but whenever you recreate the removed directory, you would have to pull the same trick again. 😞
