1 year ago Thanks for looking into this! One idea I had after opening the issue was to have your CI code check to see which snapshot build has completed more recently and use that (by default; letting people opt in to sticking with a specific snapshot site if they need to). Generally speaking, I think that both sites have gotten pretty reliable, but when one of them has trouble, the other one tends to be working.
Also, this isn't required, but would be nice: the Utah snapshots don't have
-test-in the filenames for the full distribution installers. It would be great if the Northwestern site could have symlinks w/o that bit in the name, so I can avoid adding this bit of logic.
That's because the distributions are different; the Northwestern ones include main-distribution-test (and everything that depends on). I'm open to various ideas you have for resolving this. We could ask @mflatt to include main-distribution-test or I can stop including it (probably I'd need to set up more distros to do that). Probably we do want distributions to be the same so that people who run CI actions know what they're getting, I suppose. Currently the northwestern snapshots include these packages: '("main-distribution" "main-distribution-test" "optimization-coach" "games")
These BC URLs currently fail:
* https://plt.cs.northwestern.edu/snapshots/current/installers/racket-test-current-x86_64-linux-bc.sh * https://plt.cs.northwestern.edu/snapshots/current/installers/racket-minimal-current-x86_64-linux-bc.shBut these CS URLs work fine:
* https://plt.cs.northwestern.edu/snapshots/current/installers/racket-test-current-x86_64-linux-cs.sh * https://plt.cs.northwestern.edu/snapshots/current/installers/racket-minimal-current-x86_64-linux-cs.sh
This is more complicated; the code is using the #:dist-aliases argument. I don't see any difference in the configuration for the bc and cs, however, so I'm not understanding why we see any difference between these two. In particular, for the ubuntu builds, this argument is used both for bc and cs:
#:dist-aliases (append (list (list #f #f "")
(list #f "" #f)) ;; for the cross build
extra-aliases)The extra-aliases is the empty list when building the racket-test distros and is (list (list "min-racket" #f #f)) when building the racket-minimal distros, so that doesn't seem relevant. If I'm reading the documentation correctly, the first element of the list, namely (list #f #f "") means that we'll drop the cs and bc from the name so that's not helpful. The second list, namely (list #f "" #f) means that we'll drop the "dist suffix" part of the name to make an alias, which is "precise" so we should get aliases like you're asking for from that, but the problem is that they'll have version numbers in them, not current in them because, as the docs say, only the first element of the list is used to make current links.
But I must be getting something wrong in my logic here because I see that replacing current in your desired urls above with the current version also has a cs link but not a bc link.
I'll have to try poking at and thinking about this more to figure out what's going on.

@rfindler would you be able to add symlinks for BC Linux snapshots w/o the Linux distro in the name?
