Parse debian/tests/control into runnable test descriptions: one test
per Tests: script and per Test-Command value, carrying the shared
Depends/Restrictions/Tests-Directory stanza fields and the autopkgtest
command1 enumeration (test-name overrides advance the counter).
Depends substitution is deliberately left raw: expanding @ and friends
needs the built binary list, so it belongs to the runner.
First piece of pkh test (see plans/pkh-test.md); the runner expands
these stanzas against the deb822 primitives.
Replace parse_previous_version/parse_previous_version_from_str with
parse_changelog_entries(path, limit: Option<usize>), parsing up to the
given number of entries (None: the whole file) newest-first through the
same strict entry parser instead of a header-only scan. The single-entry
helpers stay as thin wrappers, and callers needing the previous entry
now get its full source name and version, not just the raw string.
The checksum model only carried md5/sha1/sha256 while deb-buildinfo(5)
defines Checksums-Sha512, and there was no way to parse a Checksums-*
field body back into entries. Add ChecksumKind::Sha512 (computed
alongside the others), a field parser validating the
'<hex> <size> <name>' grammar, and an only-if-populated
Checksums-Sha512 emission in .buildinfo — deliberately dormant in the
dpkg-parity flows, which never emit it, and .dsc/.changes untouched.
write_paragraph emitted a bare-space continuation line for empty lines
inside a value, which parse_paragraphs treated as a paragraph separator
and silently dropped the rest of the value; blank lines are now encoded
as ' .' like dpkg does and decoded back on read. Tab-indented
continuation lines now strip exactly one tab instead of keeping it.
Clearsigned .dsc content no longer leaks armor metadata into parsed
fields: the Hash:/Comment: header and the signature trailer are
stripped before parse_paragraphs at both .dsc parse sites.
Extend the metadata writers to binary-only uploads and wire them into
the 'pkh deb' flow:
- build/binary.rs generates <pkg>_<ver>_<arch>.buildinfo/.changes
through any Context: debian/files consumption, encounter-order
Architecture accumulation (sorted in .buildinfo like dpkg-genbuildinfo),
sorted Binary lists, dpkg-formatted Description lines with udeb
suffixes, Installed-Build-Depends closure over the context status DB,
and binNMU handling (Source: pkg (prev), Binary-Only-Changes, previous
.dsc redistribution);
- artifact digests are computed inside the context via coreutils
(md5sum/sha1sum/sha256sum/stat) so chrooted/remote trees work;
- deb/local.rs runs the generation after 'rules binary', exports
SOURCE_DATE_EPOCH from the changelog (reproducibility), and resolves
vendor/profiles inside the context; deb/mod.rs retrieves the new
artifacts alongside the debs;
- reusable helpers added: FilesList::parse/render,
parse_changelog_entry_from_str, parse_previous_version_from_str,
installed_build_depends_from_content.
Differential gate: same tree built with real 'dpkg-buildpackage -b' and
with the pkh flow; .changes/.buildinfo compared field-by-field modulo
machine-dependent fields, artifact checksums included.
Replace dpkg-checkbuilddeps with a native implementation:
- full dependency grammar: comma clauses, | alternatives, << <= = >= >>
relations, :arch qualifiers (any/native/specific), [arch lists] and
<profile restriction> formulas per alternative;
- restriction reduction against active build profiles and the host arch
at parse time (reduce_restrictions semantics);
- evaluation against a parsed dpkg status database with Multi-Arch
semantics (foreign/allowed) and versioned Provides rules (unversioned
provides never satisfy versioned deps; versioned ones must satisfy the
relation);
- clause simplification with implication-based deduplication, rendering
dpkg-compatible 'unmet build dependencies/conflicts' diagnostics.
check_build_depends() consumes debian/control + CheckOpts (-A/-B/-I
equivalents). run_source_build performs the check when forced (-D
parity); source-only builds skip it entirely like dpkg-buildpackage,
and unsatisfied deps propagate as UnmetBuildDependencies -> exit 3.
Unit tests port the Dpkg_Deps.t reduction matrices; differential gate
runs 24 scenarios (alternatives, versions, arch/profile restrictions,
Multi-Arch, Provides, conflicts, -A/-B flags) against real
dpkg-checkbuilddeps comparing exit status and diagnostics.
Embed dpkg's factual cputable/ostable/tupletable/abitable data and
implement tuple/triplet/multiarch lookups, wildcard matching, arch
restriction evaluation and the full DEB_BUILD_*/DEB_HOST_*/DEB_TARGET_*
environment dump natively.
build/env.rs::arch_env now delegates to the native implementation
instead of shelling out to 'dpkg-architecture -f'.
Differential gate (build/mod.rs): arch_env(Some(a)) must equal real
'dpkg-architecture -f -a a' key-for-key for every architecture listed by
'dpkg-architecture -L', plus the native case. Data tables carry upstream
attribution comments; no dpkg code was transliterated.
Move the generic components out of src/build/ into a new src/debian/
module so they can be reused independently of the build pipeline:
deb822 control parsing (plus the debian/control model), file checksum
registry, debian/files registry, Debian version handling and changelog
entry parsing.
Merge OpenPGP clearsigning into utils/gpg.rs next to the existing key
discovery helper, making signing available outside of builds.
Delegate changelog.rs header/footer parsing to the new
debian::changelog parser, removing the duplicate regex implementation.
src/build/ keeps only build-specific logic: the pipeline driver,
build types, environment setup and the .buildinfo/.changes writers.
