Raise rate limit of particular crates? owners? for many versions of a crate per day

[carols10cents]

Currently, we have a global limit on the number of versions of a crate that can be published in one day, and the environment variable is currently set to 10 in production.

This covers 99.8% of crates, but we've recently had one case in the 0.2%: a crate that has ~30 0.x.0 releases that are all supported, and a fix that needed to be backported and published as 30 new 0.x.1 versions.

The current workaround is for the owner to contact us, we raise the global env var value for everyone to a value that would let them publish all the versions needed in one day, then contact us again when they're done and we return the env var to its original version. This works but is a lot of coordination and opportunities for mistakes.

A better solution would be if a trusted owner (user? team?) could contact us and request a more permanent higher limit, so that they don't have to contact us again every time they need to publish many versions in a day. We currently have the ability to increase the burst of publishes of new crates per-user, and the ability to increase the max_upload_size per-crate. It's not clear if this limit exception could somehow be folded into either of those systems or if a new system is needed just for this or if all need to be refactored into a new system.... details left as an exercise for the implementer 😂

For searchability, the error message you currently get when hitting this limit is "You have published too many versions of this crate in the last 24 hours".

I guess #6875 has resolved that? feel free to reopen is I misinterpreted this :)

Reopening, sorry I didn't realize this at the time you closed this -- no, the MAX_NEW_VERSIONS_DAILY/new_version_rate_limit is still global:

crates.io/src/controllers/krate/publish.rs

Lines 334 to 342 in eb5745f

	if let Some(daily_version_limit) = app.config.new_version_rate_limit {
	let published_today = count_versions_published_today(krate.id, conn)?;
	if published_today >= daily_version_limit as i64 {
	return Err(custom(
	StatusCode::TOO_MANY_REQUESTS,
	"You have published too many versions of this crate in the last 24 hours",
	));
	}
