Bug#1111950: dh-python: Please add introspection hints to dh-python helpers

[Niels Thykier]

Package: dh-python
Version: 6.20250414
Severity: wishlist
X-Debbugs-Cc: ni...@thykier.net


Hi,



```shell
$ dh_assistant list-guessed-dh-config-files
{
   "commands-not-introspectable": [
      "dh_autoreconf",
      "dh_strip_nondeterminism"
   ],
   # ... more JSON here, omitted for brevity
}
```





```
# INTROSPECTABLE: CONFIG-FILES pkgfile(bcep) pkgfile(...)
```

My argument here is that:

 1) The helper can never be skipped (so NOOP promise is not valid)
 2) The helper reacts to `debian/<package>.bcep` and similar





Best regards,
Niels

In debhelper/13.26, `dh_assistant list-guessed-dh-config-files` will now report `debhelper` commands that does not declare which config files it supports. As an example: This is in turn used by `debputy migrate-from-dh` to warn people when `debhelper` config files might be overlooked. I believe this bug can be fixed by filling out the following template and adding it in the `dh_python` command (the file found PATH - imports are not followed): If either of these are false, then please review `doc/PROGRAMMING.md` in debhelper/13.26 for alternatives or reply back to me for assistance. Note: I did not do a full analysis of which files are supported by `dh_python3`. Remember to tweak my example template above.
