I just pushed a couple of patches to staging to fix the bootstrap on aarch64, and to decrease the build time and resource usage, and the numbers are in! https://ci.guix.gnu.org/build/1632586/details 11863 seconds from downloading mrustc to building rust-1.60, for 198 minutes, or 3.3 hours. > > Is there a way to extract this information from Cuirass or the Guix data > > service? > > Maybe not from the Guix Data Service, but most likely from Cuirass and > the Guix Build Coordinator. > > For example, <https://ci.guix.gnu.org/build/1505621/details> shows the > duration, which could can also get with: > > wget -qO- https://ci.guix.gnu.org/build/1505621 |jq > > (The (guix ci) module needs an update to let you do access that info > right from Scheme.) > > Now the /search interface doesn’t have a JSON equivalent, but you can > find the build ID using something along these lines: > > --8<---------------cut here---------------start------------->8--- > scheme@(guile-user)> ,use(guix ci) > scheme@(guile-user)> (latest-evaluations "https://ci.guix.gnu.org"; 10 #:spec > "master") > $14 = (#<<evaluation> id: 739193 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "4716cea6256523a8ecf90a426d675bfb7620f3e4" channel: > "guix">)> #<<evaluation> id: 738364 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "16d4ded6302c0650978203d0df83614896c453e8" channel: > "guix">)> #<<evaluation> id: 737995 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "e61660c78f1190c578dd6f202bc5529cbdcff84e" channel: > "guix">)> #<<evaluation> id: 737588 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "88746cd80bc56212ae7922c0fa1cd9a18e44c3bb" channel: > "guix">)> #<<evaluation> id: 737529 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "ac553ba68e535810085dd838e48e4fa6ac553e67" channel: > "guix">)> #<<evaluation> id: 736841 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "7ecd85eacbfa5b7379f563b83807d3e5258cf700" channel: > "guix">)> #<<evaluation> id: 734789 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "3bb145b6e2a8c84e7739ead9ae76dc4d42bb9850" channel: > "guix">)> #<<evaluation> id: 734747 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "033cbd11a837dbc7602799f15d691221653e1996" channel: > "guix">)> #<<evaluation> id: 734733 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "c9eac0c3553703385c997a70741348ae5d34dc68" channel: > "guix">)> #<<evaluation> id: 734718 spec: "master" complete?: #t checkouts: > (#<<checkout> commit: "2589997fab07bcebe6d87fd227852389ab5b1962" channel: > "guix">)>) > scheme@(guile-user)> (define jobs (evaluation-jobs "https://ci.guix.gnu.org"; > (evaluation-id (car $14)))) > scheme@(guile-user)> (length jobs) > $15 = 76649 > scheme@(guile-user)> (car jobs) > $16 = #<<job> build-id: 1627000 status: scheduled name: "0ad.aarch64-linux"> > scheme@(guile-user)> ,use(srfi srfi-1) > scheme@(guile-user)> (find (lambda (job) (string=?
