Fails to compile with minimal dependency versions (due to old lexical-core) #1298

lo48576 · 2021-04-09T19:45:50Z

TL;DR

lexical-core dependency should be bumped to ^0.7.5.

(Strictly, it is enough if ^0.7.5 OR ^0.6.4 can be specified, but it doesn't seem to be possible with the current Cargo.toml format.)

Prerequisites

Rust version : rustc 1.51.0 (2fd73fabe 2021-03-23)
nom version : 6.1.2 (released on 2021-02-15)
nom compilation features used: any combination with lexical enabled (e.g. default-features = false, features = ["lexical"])

Test case

While I'm not sure why, this problem cannot be reproduced by tests inside the nom repository.
In order to reproduce, you have to set up another tiny crate, which depends on nom.

# Cargo.toml
[package]
name = "nom-mindep"
version = "0.0.0"
edition = "2018"

[dependencies]
nom = { version = "6.1.2", default-features = false, features = ["lexical"] }

(Actually, lexical-core = "=0.6.2" or lexical-core = "=0.7.4" seem to cause the same problem.)

// lib.rs, empty.

Then, run cargo +nightly update -Z minimal-versions ; cargo check.
Note that cargo +nightly update -Z minimal-versions only regenerates Cargo.lock with old dependency verisons as possible, in contrast to cargo update (which regenerates Cargo.lock with new dependency verisons as possible).
Once the lock file is regenerated, cargo check or normal build can be done by stable rustc.

Cause

Currently, nom depends on lexical-core crate >= 0.6, < 0.8, but this is problematic.

https://github.com/Geal/nom/blob/d1aff18e3c6b03bf3a1b6ca2826417c48995f4c1/Cargo.toml#L62

This problem is fixed by lexical-core ^0.6.4 OR ^0.7.5, so nom should pull only these newer versions.
However, it seems that cargo does not allow such "OR" condition.
In order to avoid this problem (i.e. to stop allowing invalid (non-compilable) dependency to be accepted), nom should depend on lexical-core ^0.7.5.

The text was updated successfully, but these errors were encountered:

lo48576 · 2021-04-09T19:51:27Z

I'm not sure #1156 is related, but older lexical-core seems to have caused other difficulties...

Fixes rust-bakery#1298.

simonracz · 2021-06-12T16:17:24Z

Here is a thread that explained to me what's wrong with lexical-core 0.7.4

rust-lang/rust#81654

Geal · 2021-06-19T12:46:29Z

hello, I just tried with a separate crate like you said, and rust 1.51.0, and I do not see the issue, is it still appearing for you?

lo48576 · 2021-06-19T19:49:52Z

Yes, it still happens (with rust 1.53.0 (53cb7b09b 2021-06-17)).
