ok, it turns out that this migration is quite complicated.
Here's what I plan to implement. I hope this
takes into account most common mistakes. This list below details the checks
that will be
run on debhelper or debherlper-compat dependencies. (this doc looks better with
a monospace font).
Please tell me if I missed something (or if it's too much)..
Both check can be applied on a dependency if the dependency is changed
from debhelper to debhelper-compat:
** debhelper dependency check
Depending on ~debian/compat~ content and ~debhelper~ depencency value,
the check and fix steps will behave this way:
| compat | debhelper version | check | fix
|
|--------+------------------------+--------------------------+-------------------------------------------------------|
| undef | undef | error | error
|
| undef | defined | warn missing compat | set compat to dh
version |
| < 9 | consistent with compat | warn about old compat | update compat
and dh version |
| < 9 | inconsistent | warn about old compat | update compat
and dh version |
| >=9 | ignored | warn no debhelper-compat | change
dependency to debhelper_compat = $compat_value |
Note that all check are tried one by one. More than one fix can be
applied. For instance, during a fix, a ~compat~ set to 8 is changed to
12, then the ~debhelper~ dependency is changed to ~debhelper-compat =
12~ and ~compat~ is deleted by the rules shown below.
** debhelper-compat dependency check
Depending on ~debian/compat~ content and ~debhelper-compat~ depencency
value, the check and fix steps will behave this way:
| compat | debhelper-compat version | check | fix |
|-----------+--------------------------+-------------------+-------------------|
| defined | defined | warn extra compat | delete compat |
| undefined | < current dh compat - 1 | warn too old | update dependency |
** global check
need to check in Buid-Depends that debhelper and debhelper-compat do not coexist
