These are valid warnings, and those systems must be fixed. Can you<br>
give me a list of the affected systems, so I may send patches<br>
upstream?<br>
<br>
Background: Secondary systems (systems loaded in a .asd file beside<br>
the "primary" system that the .asd file is named after) that do not<br>
follow the / convention can't be found by name by ASDF before the .asd<br>
file is loaded; they can clash with other systems and then cause<br>
"interesting" behavior. They were an abuse that kind of worked but not<br>
really from the bad old ASDF 1 days. ASDF 3 fully supports secondary<br>
systems, but requires them to start with a prefix of foo/ where foo is<br>
the primary system name (that the .asd file is named after). The old<br>
behavior is still supported at this time, but we started issuing<br>
warnings this year, together with other deprecation warnings.<br>

The best way to disable to warnings is to fix the 12 affected libraries.<br>
<br>
If you modify ASDF to remove that message, please change all<br>
occurrences of "3.3.0" to "3.3.0.0.1" in the sources, too, to indicate<br>
one local change.<br>
<br>

ASDF won't stop supporting that feature for at least the next 2 years.<br>
Those 12 libraries will have that much time to be fixed. If the last<br>
maintainers have quit, the libraries will have to be taken over by<br>
e.g. sharplispers some time before then.<br>
<br>
Experience shows that 2 years is about the time it takes for some<br>
change to "fully" propagate through the Common Lisp community (e.g.<br>
for a new version of ASDF to be used by all implementations). It is<br>
not an unreasonable target for backward compatibility of ASDF. I see<br>
no good reason to keep 15 or 26 year old bugs around indefinitely.<br>
<br>
SBCL does introduce new warnings at times, that sometimes affect tens<br>
of existing systems (e.g. the quit / exit renaming). I see no<br>
principled reason for SBCL to shy away from legitimate warnings from<br>
ASDF. How long did SBCL maintain backward compatibility with the old<br>
calling convention?<br>
<br>
PS: I wrote a function<br>
ql-test:find-misnamed-secondary-asdf-systems-in-quicklisp in my system<br>
ql-test <a href="https://gitlab.common-lisp.net/frideau/ql-test" rel="noreferrer" target="_blank">https://gitlab.common-lisp.net/frideau/ql-test</a> and it finds<br>
330 suspect defsystem entries in quicklisp. Some are templates that<br>
can be ignored (and probably filtered out of this function), but most<br>
are legitimate issues that must be fixed in the next two years.<br>
