The vendor tarball excludes pcre2-sys's bundled sources via exclude-crate-paths, but that only matches a directory name. If a pcre2-sys update moved them, the exclusion would silently stop applying and we would be back to shipping (and possibly building) a second copy of PCRE2. Inspect the generated archive against a small denylist instead, so that shows up as a packaging failure. Longer term vendor-filterer itself should support an allowlist for C sources.

Follow-up to #2495, and stacked on it: the first commit here is #2495's.
exclude-crate-pathsonly matches a directory name, so if a pcre2-sys update moved its bundled sources the exclusion would silently stop applying.cargo xtask packagenow reads the generated vendor tarball and fails if it contains any.c/.hfiles from pcre2-sys (a small denylist, easy to extend to other-syscrates).Testing, on a 16-core RHEL 10 devspace with stable Rust:
cargo test -p xtask(15 passed, including new table-driven tests) and the Makefile's clippy config are clean.cargo xtask packageproduces a vendor tarball with no pcre2-sys.c/.hfiles, andbootcbuilds from the source and vendor tarballs withcargo build --offline, linking the systemlibpcre2-8. With the #2495 exclusion reverted,cargo xtask packagefails listing the 76 bundled files.just packagebuilds the RPMs.Related: #2495 (comment)
