[issue30284] Build CPython out of tree with a read-only source tree

STINNER Victor added the comment:

I don't think that the test_pydoc failure is very important. I'm not interested 
to fix it right now.

The main blocker issue was regrtest and it's now fixed in the master branch.

I don't recall any user complaining about issues with read-only source tree, so 
I don't think that it's worth it to backport the fix. If I'm wrong, please 
comment the issue ;-)

STINNER Victor added the comment:

test_synopsis_sourceless() should create a script, build it and test the 
generated .pyc file. So we control how the .pyc file is created.

[issue30284] Build CPython out of tree with a read-only source tree

[STINNER Victor]

New submission from STINNER Victor:

I tried to build CPython out of the source tree with a customized read-only 
source tree (chmod -R -w). I got an error when running tests: tests want to 
write into a build/ directory... in the source tree.

Attached patch fixes this issue.
