Contribute a RISC-V 64 JIT backend
by Logan Chien 12 Aug '24

12 Aug '24

Hi all, I would like to contribute a RISC-V 64 JIT backend for RPython. I have made some progress at the end of 2023. ## Status My prototype can pass the test cases below: * test_runner.py * test_basic.py and almost all test_ajit.py related tests (except test_rvmprof.py) * test_zrpy_gc_boehm.py I am still working on test_zrpy_gc.py though (p.s. I can pass this if I disable malloc inlining). I haven't done a full translation yet. ## Logistic I wonder how you would like to review the patches? I have roughly 73 pending commits. Each commit has a specific reason for change and corresponding test cases (if applicable). Is it better to just send one GitHub Pull Request containing all of them? Or, do you prefer one commit per Pull Request? Thank you. Regards, Logan

Release v7.3.15 of PyPy
by Matti Picus 15 Jan '24

15 Jan '24

I have prepared a new release of PyPy. This is mainly a bugfix release to fix backward compatibility in c-extensions that use the buffer protocol. It also includes chages from our move to Git/Github. The pre-release tarballs are now on https://buildbot.pypy.org/pypy/ (until the CDN percolates them out to https://downloads.python.org/pypy/), the checksums are on a Pr to pypy.org at https://deploy-preview-110--keen-mestorf-442210.netlify.app/checksums. The release notes are at https://doc.pypy.org/en/latest/release-v7.3.15.html. Please test out the source tarballs, they have changed since they are from a git repo. I plan to release officially later today. Matti

Moving to github
by Matti Picus 02 Jan '24

02 Jan '24

Now that 7.3.14 has been released, I would like to move the canonical repo for pypy and rpython to github. Reasons: - foss.heptapod.net is not well tracked in google/bing/duckduckgo search, so people find it hard to search for issues in the project - since the site has tightened its spam control, we get reports that users create issues only to have them flagged as spam - open source has become synonymous with github, and we are too small to change that - Much of the current development comes as a reaction to fixing issues. Tracking interlocking issues is easier if all the code is on the same platform - The FAQ [2] presents two arguments against the move. Github notes [3] solves much of point (1), although not entirely. But the main problem is point (2), it turns out that __not__ moving to github is an impediment to contribution and issue reporting. - As development effort winds down, github is a better archive for PyPy than foss.heptapod.net. I cannot predict the future, but if there is a move to revive the project, or to move to another platform, I believe github will provide a better jumping-off point as well. And since the repo at foss.heptapod.net will not be deleted, even if I am wrong I expect the effort to port the issues and commits from github will be manageable. - People who wish to continue to use mercurial can add a cron job github action to pull the changes from foss.heptapod.net across to github - github is more resource rich than foss.heptapod.net. We can add CI jobs to replace some of our aging buildbot infrastructure (still using buildbot 0.8 and python2). Technique: These steps will be done in a private repo - I will convert the repo to git and add a note to most of the commits (where I can) which will allow using "git log --notes=branch" to determine which branch a commit came from. More details at [0] - I will convert the issues and PRs to github via [1]. Using a private repo prevents spamming issue authors with emails about the transfer. Then I will make the repo public: - Move it to github.com/pypy/pypy - Freeze the issue tracker at https://foss.heptapod.net/pypy/pypy/-/issues, and add a message that development has moved - Write a blog post - Modify the links in the documentation - Activate the github action in [3] to add a branch note to each git commit Anything else? Any suggestions to make the transition easier?
