@mumoshu any thoughts on this error? (see first comment)

This was working fine and is now failing with no changes to the variant files or the build approach.

Thanks for reporting. Seems like a regression introduced by recent change. I’ll investigate further and add regression test for that later!

johncblandii (Cloud Posse)

i’m curious why it’d be a problem since we’re downloading a specific version

mumoshu avatar

ah, im in doubt that go build is actually download the latest version of variant2

johncblandii (Cloud Posse)

this is the docker build, btw.

# Builder for the nbo CLI

FROM golang:alpine3.11 as cli

RUN apk add -u make

WORKDIR /usr/cli

# Install variant
RUN wget <https://github.com/mumoshu/variant2/releases/download/v${VARIANT_VERSION}/variant_${VARIANT_VERSION}_linux_amd64.tar.gz> && \
    tar -zvxf variant*.tar.gz variant && \
    mv variant /usr/local/bin/variant2 && \
    rm -f variant*.tar.gz

# Copy the cli directory
COPY cli .

RUN make build
mumoshu avatar

ideally export binary should produce go.mod that locks the depended variant2 to the specific version

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

make build is:

	variant2 export binary $(CURDIR) nbo
johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

< yes

mumoshu avatar

a workaround is to do variant2 export go, update/add go.sum and then go build -o nbo $(CURDIR)

mumoshu avatar

and your go.sum should contain something like the below to work:

module ....
require (
	github.com/mumoshu/variant2 vx.y.z

where vx.y.z should be replaced with the exact version of variant2 you want

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

doesn’t export go.sum

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

just a main.go

mumoshu avatar

yes. i think i missed implementing it, which is why variant2 export binary broke due to recent api changes in variant2

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

let me see if 0.33.0 works w/ the cli

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

it definitely built just fine. let me run the unit tests to validate it

mumoshu avatar

thx for confirming!

anyway, i’ll enhance export binary to also write go.sum. i’ll also see if i can bring back the old API MustEval to future versions of variant2

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

oddly the tests fail all the time now

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

even went back to the original 0.28.0 and they fail there too. very odd

mumoshu avatar

how the test failures look like?

mumoshu avatar

how are you running tests?

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

ahh…nm. this is likely due to this docker build

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

ok…going back to testing versions real quick. tests run fine in this build now

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

well…all tests pass in 0.33.0 so an upgrade may be enough to address this for now
