update some debs mostly for minimal-versions

[Eh2406]

This bumps the minimal acceptable versions in Cargo.toml to versions that are compatible with -Z minimal-versions. This is part of the process of seeing how hard this is for crates to use in preparation for getting it stabilized for use in CI, specifically upstreaming the changes required to get criterion working with it. It is easy to use if all of your dependencies support it, but much harder if trying to impose it on them.

I am not sure I have this exactly correct. There may be more things that need to be updated for the benchmarking code to work with minimal-versions. I was not able to test with all the feachers. But I have verified that docopt can be made to work with this change to regex. So it is a step in the correct direction.

Oh this one is interesting. What requires 0.6.2 specifically?

[Eh2406]

6.1 requires winapi ^0.2 and <=0.2.5 do not build on rust 1.0.

Thanks! I think this pretty much looks good to me! I'm surprised this was all that was needed. (Most of the deps are things I maintain, and most updates to those are driven by needs of the regex crate, so that probably helps.)

[Eh2406]

Also to be clear this is enough for cargo check --tests to pass in the bench subfolder, the main folder, and a copy docopt pointing at this on my windows machine. Running test, and running on other machines may find more.

Thanks!

When in the course of human events, a new version of regex is released I can make a PR to docopt, walkdir, and handlebars. :-)

[Eh2406]

To be a little more blunt, is there an ETA for a release that has this merged? Is there follow up that could hasen it?

[BurntSushi]

I don't really do scheduled releases, but I just put regex 1.0.3 on crates.io, which has this PR.

[Eh2406]

Thanks! Expect a bunch of downstream PR in soon.
