Outdated nightlies on Travis-CI

[SimonSapin]

@brson, is Cloudfront (that we seem to be using for HTTPS) doing any caching? I’m somehow getting an outdated Cargo nigthly (2014-08-19 instead of 2014-08-20) on Travis-CI https://travis-ci.org/servo/rust-url/builds/33162181

The other suspect is Travis, if they’re doing caching themselves.

Henrik from Travis CI here. We're not doing any kind of caching on this URL, my initial guess would be that something is going wrong somewhere in the CDN.

[brson]

My understanding is that cloudfront syncs every 24 hours. Unless I figure out how to make it sync with s3 more quickly I intend to just drop cloudfront. I'd love somebody to tell me which knob to frob.

[brson]

Cloudfront gives you 1000 object invalidations a month for free, so I'll look into having the bots do that automatically.

[brson]

@alexcrichton modified buildbot to invalidate cloudflare on every s3 upload of the binaries (though not docs I think). This should make the CDN sync nightlies immediately.

[brson]

@alexcrichton would you call this done?

[alexcrichton]

I haven't yet confirmed this, but yeah I'll close and we can reopen if it looks to be a problem still. I think it's done at least!

This doesn’t seem fixed, sorry :/ I just updated my nigthly from https://static.rust-lang.org/dist/rust-nightly-x86_64-unknown-linux-gnu.tar.gz and got c669411 2014-09-23, which according to http://buildbot.rust-lang.org/builders/nightly-linux is two days behind.
