Subject:  tree-wide: convert remaining varlink string fields to enum types (#41615)
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=03ee08d1d7f7901ed60b26be52ad1efb45455097;p=thirdparty%2Fsystemd.git

 tree-wide: convert remaining varlink string fields to enum types (#41615)

Follow-up to #40972. Convert remaining plain string fields to proper
varlink enum types across all interfaces, per the policy that
user-controlled/API fields should be declared as proper enums in the
IDL.

Interfaces converted:
- io.systemd.Manager — LogTarget, DefaultStandardOutput/Error,
DefaultMemory/CPU/IOPressureWatch, DefaultOOMPolicy,
CtrlAltDelBurstAction (8 fields)
- io.systemd.Unit — CPUSchedulingPolicy, IOSchedulingClass, NUMAPolicy,
MountFlags (4 fields)
- io.systemd.Machine — class, whom (2 fields, input dispatch converted
to JSON_DISPATCH_ENUM_DEFINE for automatic dashify fallback)
- io.systemd.oom / io.systemd.ManagedOOM — mode in ControlGroup (1
field)

Shared types moved to varlink-idl-common: ExecOutputType,
CGroupPressureWatch, EmergencyAction, ManagedOOMMode — these are reused
across multiple interfaces.

Each interface change includes a corresponding enum sync test to catch
future drift between C string tables and varlink IDL definitions.
