I have noticed a flurry of build failures on C-C tryserver since the end of December. Typical symptom is CalledProcessError: Command '['hg', 'unbundle', '--traceback', 'https://ftp-ssl.mozilla.org/pub/mozilla.org/thunderbird/bundles/try-comm-central.hg']' returned non-zero exit status 255 But others are also observed. According to a discussion on dev-moz-build (moz.dev.build newsgroup), https://groups.google.com/forum/#!topic/mozilla.dev.builds/rHfqih0fDMo Gregory Szorc's comment: --- begin quote I consider it a bug that we're obtaining bundles from https://ftp-ssl.mozilla.org/. All automation should be using the clone bundles / bundleclone facilities in Mercurial for cloning repos from S3 or the CloudFront CDN. See https://mozilla-version-control-tools.readthedocs.org/en/latest/hgmo/bundleclone.html. --- end quote And it was suggested that we file a bug here. So here it goes. The mentioned URL suggests that "If you think bundles should be made available, let a server operator know by filing a Developer Services :: hg.mozilla.org bug or by asking in #vcs on irc.mozilla.org." I have no idea where this "Developer Services :: hg.mozilla.org" should be mentioned in the bugzilla. Anyway, I hope the people looking after infrastructure take note. TIA I've gotten a lot of feedback that the S3 and CloudFront CDN hosting is faster and more reliable. You want to use it.
Oops. The last sentence is an extra copy from the news post. > I've gotten a lot of feedback that the S3 and CloudFront CDN hosting is faster and more reliable. You want to use it.
