Give every parser of the shared format layer a proper error enum
(thiserror): VersionParseError, ArchError, deps::ParseError (wrapping
the version and arch failures as #[source] so the context chain
survives), ControlParseError, ChecksumParseError, FilesParseError and
TestsControlParseError, each carrying its structured pieces (the
offending string, the stanza number, the field name) instead of a
pre-formatted String.
Display texts are byte-identical to the old format! strings, so
user-facing output and the message-asserting tests are unchanged; the
few tests asserting on error text now render the error first. Flow
boundaries that still take String (build::env, quirks, test::expand)
render with to_string() at the edge — typing those flows is a later
step. ControlInfo's FromStr impl follows parse_content's error type.
Two failures from resumed kernel sessions:
A resumed build re-runs debian/rules build, but the kernels keep
their wrapper-step stamps in debian/stamps and the flavour config
rule there exports .config from the annotations with no config
prerequisite: the resumed build silently kept the previous
attempt's configuration and a config edit never reached the .deb.
Dropping the stamp cache unconditionally would impose the kernel
packaging's shape on every package, so it is data-driven instead:
packages declare the caches under a resume_clear quirk, and
resumed builds remove those tree-relative paths before the build.
The inner kbuild keeps its own incremental state, so only the
cheap wrapper passes re-run and config-affected objects recompile.
A SIGKILLed build (OOM) leaves its overlay mounts and /proc bind
mount behind, and overlayfs creates root-owned work state inside
the workdir: the next plain build (recording is always on, it
replaces the session of its identity) failed to clear the
leftovers with a permission error. Session clearing now unmounts
everything under each entry at depth (re-reading /proc/mounts,
tolerating mount stacks from consecutive crashes) and escalates
through sudo; when the tree still cannot be cleared, the build
reports it and continues without a session instead of layering
over a half-cleared one.
The resolute and stonking kernels declare libelf-dev, libdw-dev and
libssl-dev unqualified, unlike the Debian control which carries the
same names qualified :native for the host-side tools (resolve_btfids,
gendwarfksyms, sign-file). The dpkg cross rules resolve an unqualified
Multi-Arch: same name against the host architecture only, so a cross
build installs no build-architecture variants and the kernel's
host-side tools cannot link (-ldw, -lelf, -lssl all fail).
Inject the :native variants for the affected series — the declared
unqualified dependencies stay, so the target-side tools keep their
host-architecture libraries. Series-scoped so the entry can be
dropped once the control is fixed upstream.
One deb block per package cannot express two series needing different
rules. Make pull and deb lists of entries, each with its own series
scope: every matching entry applies, in file order, so a stonking
entry can carry its own dependency rules next to the resolute one.
Thread the series through find_package_directory for the
package_directory lookup, which keeps its deb-then-pull fallback.
The resolute linux and linux-riscv controls declare llvm-21-dev
unqualified while their other llvm pieces are :native, so the dpkg
cross rules resolve it against the host architecture — whose
dependency closure needs python3:riscv64, conflicting with the
python3 the control itself declares :native. No resolver can install
that set; sbuild fails on it identically.
Give the deb quirks a dependencies rule set rather than a one-off
native-qualification knob: replace rewrites a declared dependency by
name with a full dependency string (qualifier, version and
restrictions included), inject adds dependencies resolved as if
declared, drop ignores declared ones. Entries are scoped by series so
they can be dropped when the upstream packaging catches up, and rule
names that match nothing are warned about so stale quirks surface.
Ship the llvm-21-dev entry for the resolute kernels: resolve it as
llvm-21-dev:native, keeping the declared <!stage1> restriction.
- quirks: added quirks, that does nothing for now
- deb: install arch-independant dependencies (too much is better)
- deb: added linux-riscv crossbuild test
