- distro_info: malformed CSV rows are skipped with a warning, dates
that fail to parse become None, and all plain HTTP requests go
through a shared reqwest client with connect/total timeouts
- package_info: the Sources stanza iterator is iterative (a crafted
index with many blank stanzas overflowed the stack), stanzas missing
a Version are skipped, and failed series/pocket probes are summarized
in the final 'not found' error instead of being silently dropped
- pull: no double unwrap on the remote-derived artifact filename, an
empty series list is an error, and streaming downloads get a
per-request timeout
- deb/cross: dpkg-architecture output parsing skips unexpected lines
and its exit status is checked, as is dpkg --add-architecture
- changelog: version increments parse as u64 with checked arithmetic
(1.0-20250123123456 used to panic on the u32 parse)
The Sources index was downloaded with no authentication: per-artifact
checksums were verified, but against hashes taken from an index a MITM
could substitute along with the artifacts. Fetch each suite's InRelease
(or Release + Release.gpg), verify the signature with gpgv against the
archive keyring (or the PPA signing key) the same way apt does, and
checksum-check every Sources index against it before parsing.
Distro archives and PPAs verify strictly: an invalid or unverifiable
signature, or a missing gpgv binary, is a hard error. Flat repositories
keep working without a Release file or without a verifiable one (warned
as unauthenticated), but tampering evidence is a hard error there too.
Also switches all archive, PPA and keyring base URLs to https, and
reads suite components from the verified Release instead of fetching
them separately over an unauthenticated channel.
Add a --repository flag taking the full suite URL of an external flat
repository (e.g. https://pkg.noctalia.dev/deb/resolute/), i.e. one with
no dists/ hierarchy, like apt's exact-path suites ('Suites: resolute/').
The suite name is read from the root Release file (Codename/Suite), the
sources index is fetched from the repository root as Sources.xz/gz/plain,
and package files are resolved against the URL root, ignoring the stanza
Directory field like apt does. As with PPAs, the stanza Vcs-Git is never
used for external repositories, so the source always comes from the
repository itself.
Also make the sources index parser detect compression by magic bytes
(gz/xz/plain) instead of assuming gzip, and fix extraction of archives
with './'-prefixed entries, which previously aborted and are now
extracted in place instead of being relocated.
The Ubuntu development series (stonking) Sources.gz no longer ships a
Checksums-Sha256 field, only Checksums-Sha512 and the legacy Files
(MD5) field. The package_info parser only read Checksums-Sha256, so
the file list ended up empty and fetch_orig_tarball panicked on
Option::unwrap() when looking for the orig tarball.
- Add a ChecksumAlgo enum (Md5/Sha256/Sha512) to FileEntry, replacing
the hardcoded sha256 field, and parse the strongest available
checksum field (Sha256 > Sha512 > MD5).
- Make download_file_checksum verify against the correct algorithm
instead of always using SHA-256.
- Replace the unwrap() on the orig tarball search with a proper error
listing the available files, so future regressions fail clearly
instead of panicking.
- Add md-5 dependency for MD5 verification.
Multiple changes:
- New contexts (schroot, unshare)
- Cross-building quirks, with ephemeral contexts and repositories management
- Contexts with parents, global context manager, better lifetime handling
- Local building of binary packages
- Pull: pulling dsc files by default
- Many small bugfixes and changes
