This has been true since https://chrome-internal.googlesource.com/chrome/ios_internal.git/+/08f2e7192747c857ea971eb5d1e0a15c03819e68, which was based on discussions with olivierrobin, smut, and others, and defined the Canary artifacts as just:

canary.ipa
hybrid.ipa
infobar.ipa
prototype.ipa

Do we really need the other packages for Canary builds?

We do need dogfoody.ipa out of the list of those other packages. Where do we find dogfoody.ipa now?

It's only archived as part of the non-Canary builds, e.g.:

https://pantheon.corp.google.com/storage/browser/chrome-signed/ios-G1N/55.0.2883.55/iphoneos10.0/ios/920/

I don't thing dogfoody should be generated by the canary bot, but by ios bot.
Why would we need a M57 dogfoody?

Well there is an M57 dogfoody for dev channel, but it's emitted by "ios".

We use dogfoody build for our Dev channel and it should be of the same Milestone with Canary. Canary is M57 now and Dev build (dogfoody) should be the same. Where do I find the M57 dogfoody build Sana?

Like I said, "ios" will produce the M57 dev channel dogfoody.ipa. "ios" compilation is failing though so it won't be available until https://crbug.com/667928 is resolved.

The link you posted in #0 is for "ios-canary". This does not have dogfoody.ipa. Only "ios" does.

Thanks!

Dogfoody available here:

Thanks!
