can't build on go1.11-1.11.3 because of "go 1.12" declaration in go.mod

[brent-holland]

Upgrading to go 1.12 broke compatibility with google functions, which only supports 1.11. I get the following error trying to deploy a golang google function using this library (which is, in turn used by google's bigquery library. I'm going to try to downgrade to an earlier version

Deployment failure:

Upgrade your Go 1.11. That error message is a bug and was fixed in a Go 1.11.x point release.

[brent-holland]

I'm not sure you understand. This error is happening when attempting to load my golang code into a google function. I have no control over the golang runtime used in the google function

[bradfitz]

@jadekler @broady @andybons @stewblr -- which version of Go 1.11.x is Google Cloud Functions using? It might be too old.

[broady]

Thanks, it looks like it's on Go 1.11.5 right now, though that was only updated a few days ago, so might not have hit production yet. Before that, it was on Go 1.11.0.

I just sent a change to update it to 1.11.6.

[stewartreichling]

We're in the process of updating to Go 1.11.5.

[bradfitz]

Go 1.11.4 or later is fine per https://tip.golang.org/doc/go1.12#modules

[bradfitz]

What were we on before "in the process of updating to Go 1.11.5"?

[broady]

What were we on before "in the process of updating to Go 1.11.5"?

"Before that, it was on Go 1.11.0."

great, we're on track for 1.11.5 very soon, then, and we should be able to get to 1.11.6 a bit later.

[bradfitz]

Sorry, I shouldn't reply to bugs while watching a meeting. 🙄

[brent-holland]

we're on track for 1.11.5 very soon

Not to press, but do we have an ETA as to when this will be available for use in GCP?

[stewartreichling]

Hi Brent,

I can't give a fixed timeline as it depends on some releases landing. This should hopefully make it into the next release. In the meantime, you could depend on an older version of the libs, e.g.,:

module my_module

require cloud.google.com/go v0.37.0

[brent-holland]

@stewblr I tested and using this version did get my function working. Thank you for your help.

[stewartreichling]

Glad to hear the temporary fix worked.
