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.
set only replaced the first match and appended otherwise, so a
paragraph holding both 'Depends:' and 'depends:' kept a stale second
value after an update, silently re-emitted on serialization. set now
updates the first match in place and removes any other case-insensitive
duplicate; the parser stays lenient and keeps duplicates reachable via
iter().
CheckOpts had no build-arch concept: the build-side facts and :native
qualifiers resolved against the host arch, so in a cross build
(-a armhf on amd64) 'Build-Depends: foo:native' looked for an armhf
package where dpkg-checkbuilddeps looks for an amd64 one. CheckOpts
gains build_arch (DEB_BUILD_ARCH), used for :native and the dpkg status
attribution; bracketed arch restrictions keep evaluating against the
host arch.
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.
Debian Policy 7 defines the deprecated single-character spellings as
'earlier/later or equal' (i.e. <= and >=), and dpkg still accepts them
that way; the parser mapped them to the strict << and >> instead, so
'foo (< 1.0)' was wrongly reported unmet against installed 1.0.
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.
Implement the documented dpkg ordering algorithm (Debian Policy 5.6.1):
numeric epoch, then upstream/revision compared as alternating non-digit
and digit chunks, with '~' ordering before anything including the empty
chunk and letters before non-letters in non-digit chunks.
Adds Ord/PartialOrd for DebianVersion, a free compare() and a
later_than() convenience.
Unit tests port all vectors from dpkg's scripts/t/Dpkg_Version.t plus
Ubuntu-flavored cases (security uploads, ~ppa1 backports). Differential
gate: every vector cross-checked against real 'dpkg --compare-versions'
for <<, <=, =, >= and >>.
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.
Add an automated differential test harness in build/mod.rs that builds
the same source tree twice - once with real 'dpkg-buildpackage -S
-I -i -nc -d --no-sign', once with the native pipeline - and compares
all produced artifacts:
- .dsc payload byte-for-byte,
- .changes field-by-field (checksum lines of the .buildinfo itself
excluded, as its content legitimately differs on machine-dependent
fields),
- .buildinfo structure (Installed-Build-Depends, Environment,
Build-Date and Build-Tainted-By excluded).
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.
