Wrong keystroke in the wrong buffer because misuse of the Ludo=E2=80=99s code. :-) On Wed, 23 Dec 2020 at 11:19, zimoun wrote: >> I wanted to evaluate that by looking at store items corresponding to >> subsequent revisions of a package (be it different versions or rebuilds >> induced by dependencies), and this is what the program below does. What I wanted to illustrate is =E2=80=9Crevision=E2=80=9D does not mean =E2= =80=9Cnew version=E2=80=9C and I do not know what is the typical usage by people; aside Guix dev. :-) How many times per week or month people are doing =E2=80=9Cguix pull && guix upgrade=E2=80=9D almost blindly without reviewing what is new? Last, I was trying to understand what is the =E2=80=9Crevision=E2=80=9D num= ber corresponding to which outputs. For example r-minimal: There are 3 outputs with 4.0.3, so I am expecting 3 similar revisions in the chart. Then 3 others with 4.0.2, then 2 others with 4.0.1. In the 6 revisions in the chart, I was trying to figure out what does mean the =E2=80=990=E2=80=99: r-minimal against which other one, i.e., whic= h Guix commit against which other one. Idem for 1,2,3,4,5. :-) BTW, really interesting topic! Thanks Ludo. :-) Cheers, simon
