buildbot won't fetch from its local distfiles mirror

[jmroot (Joshua Root)]

See for example: ​https://build.macports.org/builders/ports-11_x86_64-builder/builds/31159/steps/install-port/logs/stdio

All our mirrors except distfiles.macports.org are blacklisted on the buildbot, but that too has been removed from the list by [c792d69107dafe324d341408e548eff87e7a356b/macports-ports] on newer OS versions.

Yes, that's right.

Next month, when our CDN bandwidth resets, I'll reinstate the use of the CDN. We just need to make sure we stay within the free monthly bandwidth/usage limits they've given us, which is not straightforward because they haven't given us any way to see how much of the credit we've used.

Technically on the buildbot worker "distfiles.macports.org" is not the CDN; there's local DNS overrides that point that hostname at the local server. Ideally I would like to tell MacPorts on the buildbot to use a different hostname, like distfiles.internal.macports.net, for getting distfiles, and get rid of the DNS override.

The point is you should probably un-blacklist at least one of the other mirrors in the meantime, or builds will keep failing when the distfile is no longer available from the upstream site.

[ryandesign (Ryan Carsten Schmidt)]

Short of explicitly listing each mirror that we want to blacklist, I don't think we have syntax to do that.

I'm working on fixing the problems with master_site_local and patch_site_local that currently prevent them from being used for this; see #62143.
