DFSG NEW review for bazel-aspect-bazel-lib version 2.22.5-1

Summary

• Licensing is DFSG-compliant and debian/copyright is accurate: Yes
• Packaging is of good quality: No
• Issues: 0 blocker, 2 important, 2 minor
• debian/watch: old format (version 4)
• debian/copyright: machine-readable

Licensing

The whole upstream tree is Apache-2.0: the single root LICENSE is the Apache 2.0 text, a whole-tree, case-insensitive scan found no other licence text (no GPL/LGPL/BSD/MIT/ISC/MPL/CC/"public domain"), and the only copyright holders named by file headers anywhere are "The Bazel Authors" (years 2017-2024), matching debian/copyright. No embedded/vendored third-party code with its own licence, no non-free clauses, and no minified/compiled files are shipped (prebuilt toolchain binaries are only fetched at build time by upstream rules, never part of the source or the .deb). debian/copyright is DEP-5 machine-readable with the exact 1.0 Format URL, a Files: * catch-all stanza and a separate debian/* stanza, both Apache-2.0 with the text correctly deferred to /usr/share/common-licenses/Apache-2.0. Accurate and complete.

Packaging

The packaging skeleton is sound (compat 13, empty override_dh_auto_{build,install}, reproducible mtime touches, Architecture: all / Multi-Arch: foreign, offline autopkgtest, all binary Depends exist in the archive). But the single quilt patch removes the jq.bzl/yq.bzl/tar.bzl module dependencies from MODULE.bazel while leaving lib/yq.bzl and lib/tar.bzl loading @yq.bzl/@tar.bzl, so the shipped transitional shims cannot be loaded; only lib/jq.bzl was stubbed, inconsistently. debian/README.source misdescribes what the patch does, and the autopkgtest command line supplies no offline source for the bazel_features/bazel_skylib/platforms modules the installed MODULE.bazel requires, so bazel test //... cannot resolve them.

Issues

1. [important] [packaging] Installed lib/yq.bzl and lib/tar.bzl load modules the patch removed

• Files: lib/yq.bzl:6, lib/tar.bzl:6-7, lib/BUILD.bazel:125,135,214, debian/patches/0001-debian-offline-and-self-contained.patch
• Evidence: lib/yq.bzl:6 load("@yq.bzl//yq:yq.bzl", _yq = "yq"); lib/tar.bzl:6-7 load("@tar.bzl//tar:mtree.bzl", ...). The patch deletes bazel_dep(name = "jq.bzl"), yq.bzl, tar.bzl from MODULE.bazel but only rewrites lib/jq.bzl (to jq = None), leaving yq/tar untouched.
• Problem: The yq.bzl and tar.bzl modules are not declared by the installed MODULE.bazel and in the offline Debian setup exist nowhere (bazel_lib 3.x no longer depends on them). Any load("@aspect_bazel_lib//lib:yq.bzl", ...) or ...lib:tar.bzl therefore fails at analysis. The shipped files are internally inconsistent with the patch: jq was stubbed to fail softly, yq/tar were left hard-broken, and the bzl_library deps still reference @yq.bzl//yq, @tar.bzl//tar, @jq.bzl//jq.
• Fix: Treat all three back-compat shims the same way (e.g. stub jq/yq/tar to None as done for jq.bzl, or drop the files and their bzl_library deps), so the installed tree either loads or clearly signals the move to bazel-lib 3.x.

2. [important] [packaging] autopkgtest cannot resolve bazel_features/bazel_skylib/platforms modules

• Files: debian/tests/test-001, debian/tests/test-001-artifacts/MODULE.bazel, MODULE.bazel
• Evidence: test-001 sets --registry=file://"$MOCK_DIR" (mock contains only apple_support, buildozer, protobuf, zlib) and overrides only aspect_bazel_lib, bazel_lib, stardoc, rules_shell. The installed MODULE.bazel still declares non-dev bazel_dep(name = "bazel_features" ...), bazel_skylib, platforms, and kills the network via http_proxy=127.0.0.1:9.
• Problem: With the registry replaced by the mock (all network blocked), the module-graph resolution of bazel test //... has no source for bazel_features 1.9.0, bazel_skylib 1.8.1 and platforms 0.0.10, which are not overridden and not mocked. The test as written cannot run offline. Other Debian bazel-* packages install these modules under /usr/share/bazel, but nothing in this test points at them.
• Fix: Add --override_module entries (or the three modules to the mock registry) for bazel_features, bazel_skylib and platforms, or otherwise document and provide their offline source; then verify the autopkgtest passes in debci.

3. [minor] [packaging] debian/README.source misdescribes what the quilt patch does

• Files: debian/README.source
• Evidence: "quilt patches restore the self-contained v2 Starlark rule implementations and replace network downloads in toolchains with local Python/shell scripts and system binaries so that builds work completely offline across all Debian architectures."
• Problem: The only patch (0001) edits MODULE.bazel (module version, dev_dependency flags, removal of the jq/yq/tar back-compat deps and toolchain registrations) and stubs lib/jq.bzl. It restores no v2 rule implementations and replaces no network download; the installed v2 files remain thin re-export bridges to @bazel_lib 3.x. The description misleads the reviewer and future maintainers about the offline mechanism (offline works via the bazel-lib package, not via this patch).
• Fix: Reword README.source to state that the patch removes network-dependent toolchain registrations and the unpackaged jq/yq/tar bridge modules, relying on the installed bazel-lib (3.x) package for the rules and their toolchains.

4. [minor] [packaging] debian/watch is in the old version 4 format

• Files: debian/watch
• Evidence: version=4
• Problem: Version 5 is the current format of debian/watch.
• Fix: Convert it to version 5; a mechanical conversion is under Proposed changes.

Verified

• Read all of debian/: control, rules, changelog, copyright, install, README.Debian, README.source, gbp.conf, source/format, patches/series and 0001 patch, tests/control, tests/test-001 and its artifacts, upstream/metadata.
• Whole-tree grep (excluding .pc/ and debian/) for Copyright, (C), (c) (via copyright), ©, SPDX, Licensed under, and for MIT/BSD/ISC/Mozilla/LGPL/GPL/CC/public domain/non-commercial: only the Apache-2.0 root LICENSE and "Copyright The Bazel Authors" headers (2017, 2018, 2019, 2024) in a subset of lib/ files. No other licence text anywhere.
• Globbed tree structure (root, lib, lib/private, tools, platforms, shlib, docs, e2e, .aspect, .bcr, .github, debian); only one LICENSE file, no NOTICE/AUTHORS/COPYING in any subdirectory, no vendored third-party tree.
• Read MODULE.bazel, lib/jq.bzl, lib/yq.bzl, lib/tar.bzl, lib/testing.bzl, lib/copy_file.bzl, lib/copy_to_bin.bzl, lib/diff_test.bzl, lib/copy_directory.bzl, lib/private/copy_to_directory.bzl, lib/private/copy_to_directory_toolchain.bzl, lib/BUILD.bazel, root LICENSE/README.md.
• Checked every file named in debian/install exists in the tree; every Depends in the binary (bazel-features 1.11.0, bazel-lib 3.7.2, bazel-platforms, bazel-rules-shell, bazel-skylib, bazel-stardoc) and bazel-bootstrap exist in the archive via apt-cache.
• Debian Policy current Standards-Version is 4.7.4.1 (package declares 4.7.2); A10.2/A10.3 changes (source Priority prose, Git-Tag-* fields, linker scripts, non-free-firmware) do not affect this package.
• dh_install compat 13 confirmed to support ${env:VAR} substitution.
• uscan found upstream releases with debian/watch; a newer upstream version is available (upstream 3.7.3, packaged 2.22.5), which is not a fault of the package.

Not confirmed

• Could not run the autopkgtest (bazel-bootstrap/bazel not installed on this system); the claim in the issue is derived from the module graph vs. the test's override/mock/registry set.
• Did not open binary fixtures (e2e/coreutils/test.bin, e2e/copy_to_directory expected/*) - recorded by name; none are installed by the package and none carry code.
• Could not confirm whether the Debian test environment supplies an offline module registry or /etc/bazel/bazelrc that the autopkgtest relies on (this system has no /etc/bazel).
• debian/watch not reviewed (out of scope).
• Why the model asked for what a review has no use for. During this review it asked once for something outside the package and the reviewing system (another file of the sandbox, or a URL), or was given part of the review tooling's own configuration, and that was refused or withheld. A model does this when something it has read tells it to, so look in the package for text addressed to a reviewing program, and treat this report with suspicion. Refused: read: "xd://" is not a file of the package or of the reviewing system.
