Agreed. Still, in my experience, problems that are not seen on |
17 |
amd64 are the vast majority of timesinks. Usually, by the time |
18 |
non-amd64 shows up on a non-security bug, the Basic Bullshitâ„¢ has |
19 |
been sorted. And even if it isn't: Arches are usually quick to |
20 |
point it out and the rest of arches move on to the next bug. The |
21 |
truly arch-dependent bugs are what wastes my time: |
22 |
|
23 |
For example: |
24 |
|
25 |
- dependencies not being keyworded for arch or ~arch but only |
26 |
amd64/~amd64 |
27 |
- dependencies not even building on ~arch, but on ~amd64 |
28 |
- package assuming availability of gcc/ghc/Python-X.Y when |
29 |
arch/~arch only has something for <Y or <X |
30 |
- my favourite: assuming udev is at version X for arch/~arch when |
31 |
it has been broken there for roughly twelve kernel versions due |
32 |
to udev/systemd upstream not caring. The information is one |
33 |
equery-y command line away, but no, let's file that bug. |
34 |
|
35 |
Having every arch team chase the deps for every package is very, |
36 |
very frustrating, since it is so trivial a problem. We need a |
37 |
tool that answers the question: "I want to mov cat/pkg-1.2.3 to |
38 |
stable for arches a, b and c, what do I need?" for _every |
39 |
package_. Some groups seem to have tooling for this, but it is |
40 |
far from easily (obviously?) available, so every team gets to |
41 |
re-discover dependency hell. Ruby is especially bad since |
42 |
FEATURES=test make the depgraph explode (and sometimes circular). |
