PATCH 1/1 python3-native: Fix pip install issue due to unclean build directory

In reply to a message not in the archive

When installing python3-native sometimes pips default build directory (which is on the host and is user dependant) is left unclean, due to this, when python3-core is being installed it tries to use the same directory producing an error, this explicitly removes what the previous installation might have left behind, fixing the issue.

The problem here is that two builds of python3-native could be happening on the same system at the same time. In fact I'd bet that is why its breaking on the autobuilder. Can we not tell it to use something in WORKDIR as its temp directory instead?

Cheers,

Richard

Hmm, that's potentially what is happening, in fact, my first thought was to do that and use something within the WORKDIR, but I wasn't able to do that because they do something weird to install pip, they bootstrap the installation and they use python wheels, so the actual part of the code where one could specify a different build directory for pip is inside one of the wheels, making it complicated to modify. The only other thing that occurs to me would be to just make it sleep or make it wait somehow (we could modify the queue?) until the directory is empty.

I still think this should work, I only saw cases where the build directory is left with one empty file, another reason why I decided to explicitly delete it instead of forcing it to delete everything inside the directory, disabling pip is not an option because it is required since python 3.4 as I stated on the upgrade patch, we could try this, and if it doesn't work I'll find another workaround, but let me know what you think.

I tried it on the autobuilder and it failed again. I think part of the problem is that this part of the process runs under pseudo so it thinks its root, yet can't clear root's pip directory in /tmp.

I suspect we are going to have to tell pip to use WORKDIR somehow, even if we have to patch it to take some kind of prompt from the environment for example.

Yes, the problem does happen when it uses pseudo and it thinks its root, I thought removing the files inside the same python code would be able to do it, ok I will find another workaround.
