control: retitle -1 dh-rust: please support install without dependent crates installed control: severity -1 wishlist
Quoting NoisyCoil (2025-02-08 15:12:22) > I confirm the analysis of this bug which I gave in #1094199. Both bugs are the > manifestation of the same underlying implementation bug: dh-rust relies on > `cargo package` to normalize the crate and to include/exclude the desired > files > from the Debian package. At this time, `cargo package` always generates or > creates a Cargo.lock file in the package, which requires the local registry to > be populated with all dependencies. > > For what concerns this bug, cargo's behavior forces build-dependencies to be > installed even when they are not needed at all for the purposes of Debian > packaging: Cargo.lock is deleted from the package anyway.

Upstream it is causing a > number of issues too, see e.g. [1] and [2]. > > The situation got (probably one order of magnitude?) worse with cargo 1.84, > which started to create lock files not only for binary crates and for library > crates with examples, but for *all* crates.

An example of a package that I > could test to build with cargo 1.83 but not with cargo 1.84 is rust-nanorand > 0.7.0-11, which just yesterday was updated to 0.7.0-12 in order (among other > things) to remove the <!nocheck>s. As I also wrote at #1094199, this is a bug against dh-rust, and since your arguments seem to be targeted at making changes to cargo, they are likely better suited at a separate bugreport. I have tried clarify this by changing the title for this bugreport. Please track changes to cargo independently of this bugreport, and use this bugreport only to track e.g. implementing support in dh-rust for some future imaginative cargo command-line flag or environment variable.
