Unfortunately TKLBAM is still in Python2. Ideally we should update it to python3, but until then we use pypy. Even though Python2 is EOL, PyPy still maintain their Python2 build.
This repo builds a Debian package of pypy2 for use by TKLBAM. The packaging is a bit hacky and nothing close to meeting Debian policy, but for our purposes it's "good enough"...
To build PyPy from source, python2 is required. We do that by downloading the pre-compiled binary provided by upstream.
Compare the PYPY_BUILD_DEP_VERSION in pypy-versions.txt against the latest upstream PyPy stable pypy2 release here:
https://downloads.python.org/pypy/
That will determine the pre-compiled version that is downloaded at build time.
If there is a newer version, first update the value of PYPY_BUILD_DEP_VERSION in pypy-versions.txt.
Then update the checksums in the 2 checksum files:
with the relevant checksums for the newer download - be sure to the 'pypy2.7-vXXX' checksum for:
- checksum-amd64.txt (with checksum for linux64.tar.bz2)
- checksum-arm64.txt (with checksum for aarch64.tar.bz2)
The checksums can be found here:
https://pypy.org/checksums.html
Note that we use the .tar.bz2 tarball but ONLY the checksum should be replaced in those files - the noted file name ('pypy-bin.tar.bz2') should not be changed.
The latest stable source will automatically be pulled from their git source. However as an additional check, we also double check the git commit ID of the matching version.
To get the commit ID, check the PyPy source releases page for the latest stable release - it should generally match the version of the precompiled source - as discussed above.
https://github.com/pypy/pypy/releases/tag/
Once you have the matching version, ensure that you update the commit ID in the 'src-commit-id.txt' file.
FWIW I usually right click on the short commit ID on the release page. Then "copy link" and paste the whole URL into the file and then remove everything but the SHA.
Assuming building with pool with everything set up ready to go, before running 'pool-get . turnkey-pypy2' be sure to load the relevant deckdebuild env vars.
An easy way to do that is to just source the 'DECKDEBUILD_ENV' file in the repo prior to running pool-get. Alternatively, you can just prefix the pool command:
DECKDEBUILD_FAKETIME=false DECKDEBUILD_MOUNT_PROC=true pool-get . turnkey-pypy2
If you do not set those vars (which as the var names suggest; disable faketime & mount /proc), the build will fail. in the git repo.
