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.
Two read_file(...).unwrap_or_default() calls masqueraded IO errors as
empty data: an unreadable debian/files became 'binary build with no
binary artifacts found; cannot distribute', and an unreadable dpkg
status file produced an empty Installed-Build-Depends. Tolerate a
missing debian/files (first build in a fresh tree) but propagate real
read errors, and hard-error on an unreadable status file like the
source-build path does. installed_build_depends_from_content also
returned a bare newline for zero entries, defeating render_buildinfo's
empty-guard and emitting a malformed 'Installed-Build-Depends:' field
with a blank continuation; it now returns an empty string so the field
is omitted.
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.
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.
Replace the 'dpkg-buildpackage -S' wrapper with a native pipeline in
src/build/:
- deb822 control parser/writer with dpkg-compatible multiline rendering
(control.rs)
- md5/sha1/sha256 checksum registry, insertion-ordered like dpkg's
artifact accumulation (checksums.rs)
- Debian version splitting/validation and full changelog entry parsing,
including binNMU binary-only entries (metadata.rs)
- build-type bitflags and rules-target/artifact-suffix mapping
(buildtype.rs)
- environment setup: SOURCE_DATE_EPOCH, DEB_BUILD_OPTIONS,
dpkg-architecture env dump, vendor default profiles and the sanitized
Environment field recorded in .buildinfo (env.rs)
- debian/files registry with atomic saves (files.rs)
- native .buildinfo writer, including the Installed-Build-Depends
closure computed over the dpkg status database (buildinfo.rs)
- native .changes writer emitting dpkg's canonical field order with
legacy Files + Checksums-Sha1/Sha256 (changes.rs)
- gpgme clearsigning with the transitive checksum cascade
(dsc -> buildinfo -> changes), key discovery from the changelog
maintainer and UNRELEASED no-sign handling (sign.rs)
dpkg-source (-b/--before-build/--after-build) intentionally remains a
subprocess; debian/rules execution is unchanged.
Validated differentially against real dpkg-buildpackage -S -I -i -nc -d
on native and 3.0 (quilt) fixture packages: .dsc byte-identical, .changes
payload matches modulo machine-dependent Installed-Build-Depends and
Environment content, all signatures verify with gpg, artifact ordering
and UNRELEASED no-sign behavior match dpkg.
