FTBFS: git submodules
Just hit yet another instance of:
+ git clone --shared /amnesia.git/.git/modules/submodules/aufs-standalone fatal: repository '/amnesia.git/.git/modules/submodules/aufs-standalone' does not exist
(Starting from a vm:destroy'd build environment because of the ENOSPC.)
If that doesn't get fixed for real soon, we should definitely include a hint somewhere about possible workarounds.

The first build is fine but any subsequent build fails, and I need to start over (going as far as trashing the basebox), which is entirely unreasonable.
kibi@armor:~/work/clients/tails/release/release-checkout$ ls submodules/ aufs-standalone/ chutney/ jenkins-tools/ mirror-pool-dispatcher/ kibi@armor:~/work/clients/tails/release/release-checkout$ cat .gitmodules [submodule "submodules/jenkins-tools"] path = submodules/jenkins-tools url = https://git-tails.immerda.ch/jenkins-tools [submodule "submodules/chutney"] path = submodules/chutney url = https://git-tails.immerda.ch/chutney branch = feature/tails_test_suite [submodule "submodules/mirror-pool-dispatcher"] path = submodules/mirror-pool-dispatcher url = https://git-tails.immerda.ch/mirror-pool-dispatcher [submodule "submodules/aufs-standalone"] path = submodules/aufs-standalone url = https://github.com/sfjro/aufs5-standalone.git
Meanwhile, on the guest VM:

It seems getting rid of all the contents of
.git/modules, then running:
git submodule deinit -f . git submodule init git submodule update
did the trick, and I'm no longer seeing
Absolutely no idea why the first build succeeds but not the second/n-th ones… But we might need to have some kind of self-healing process following 7a4dc47c5d2e5aa57e83ddfa40cbf5964cf691cb which renamed
Maybe this depends on the git version on the host, which might explain why some developers didn't get this issue (I'm still running stretch, because ENOTIME to upgrade, plus running the test suite without the VM indirection seemed a good reason not to rush anything).

I'm very sorry the renaming of
aufs-standalone causes trouble. Previous aufsN → aufsN+1 renaming caused trouble already, which is why I wanted to do one last renaming and avoid the problem happening again.
I remember this has caused trouble for other people too. I think most developers had to do $something to cope with this renaming since September. I should have provided instructions to do so. By now, I expect all active developers have gone through this transition already and the bulk of the pain is behind us. So it might be too late now to figure out how to document a transition that actually happened in practice?
On the workaround front I can suggest:
- If you don't do this consistently already: ensure you run
git submodule update --initwhen switching between branches that have different sets of submodules. But I think it is not sufficient to address corner cases such as this one.
- Sometimes I need to
rake vm:sshand then
rm -rf amnesia.git, to workaround weird build failures (the build system does not see the branch I'm trying to build). I've still not taken time to report this, mostly because I am presently unable to describe what are the conditions for this problem to happen. Regardless, I suspect it could have solved the problem you've faced.
