10:29 <cfbolz> oh, there's a change to timsort coming

10:29 <cfbolz> https://github.com/python/cpython/pull/28108

10:59 <vstinner> cfbolz: maybe related to https://mail.python.org/archives/list/python-dev@python.org/thread/MHK54GBJRKUKMTXKUK3S52LMCWDNMZCK/

11:01 <vstinner> cfbolz: also https://github.com/LLyaudet/cpython/pull/1

11:01 <cfbolz> yep

11:01 <cfbolz> that's where I followed this from ;-)

11:03 <cfbolz> at some point we should improve our list sorting performance, which is ok, but cpython is better

11:12 <cfbolz> the new algorithm would be quite easy to port though, Tim has helpfully written up pure python versions

11:58 <joannah68> Is it possible to checkout to a former release. I want to checkout to a the last branch that had a compacting GC markcompact..or the branches for old releases are deleted.

11:59 <joannah68> ?

11:59 <cfbolz> hm, I am not sure we ever did a proper good release with that GC

11:59 <cfbolz> did you find a release number?

12:01 <joannah68> I know release-2.0-beta1 still had it but I dont know if that is the latest release where the GC still existed.

12:03 <cfbolz> joannah68: ok, so there is a release-2.0-beta-1 branch in the repo

12:16 <joannah68> OK, found it, i guess it will need some fixing, wont compile correctly.

12:16 <cfbolz> yeah

12:16 <joannah68> It looks like it was the last release with that gc

12:16 <cfbolz> joannah68: from which year is that?

12:17 <joannah68> 2013 I guess

12:18 <cfbolz> joannah68: the last times I tried to build old pypys I actually used a virtualbox with old ubuntus 😓

12:20 <joannah68> Are you saying if I used an old ubuntu, i wont have to be fixing any things, will work as is?

12:24 <cfbolz> joannah68: yeah, that's what I did

12:28 <joannah68> I will do that....thanks
