Glide: Update failed for appengine/cloudsql: Cannot detect VCS

[itscaro]

I'm stuggling with go 1.6 and glide 0.9

I got this error when getting go-sql-driver/mysql

Any ideas?

[akutz]

HA! I'm literally trying to solve the _same_ issue! https://travis-ci.org/emccode/rexray/builds/110459662

[bwiggs]

Same here:

[akutz]

FWIW, not Go 1.6 issue as happened on 1.5.1 on Travis as well. I bumped to 1.6 to see if that helped. Same error. See previous builds in my linked build's history for same error with 1.5.1.

[akutz]

Here's a build with 1.5.1 with same error. https://travis-ci.org/emccode/rexray/builds/110452312

@itscaro @bwiggs are you pulling the tip of master or using the released version?

@akutz I see your case. It's pulling the tip of master. I think you're seeing a problem because of #267. If you build in appengine there are some special appengine packages available. The change in #267 allows glide to scan all possible dependencies, irregardless of build mode, so it can get the full picture. Unfortunately, that means it tried to find appengine based dependencies as well.

I'm debating between two possible fixes.

1. Skip appengine dependencies.
2. Provide a flag to only build for the current environment (GOOS/GOARCH)

[akutz]

Hi @mattfarina,

FWIW, here's the bit from the Makefile that handles Glide. In a branch I update REX-Ray to use Gomk for builds, which I've designed to enable selecting the version of Glide I want to use. Currently it's using the tip of master.

deps: _pre-make _deps _post-make
_deps:
    @if [ -z "$$OFFLINE" ]; then \
        echo "target: deps"; \
        printf "  ...installing glide..."; \
        go get github.com/Masterminds/glide; \
            $(PRINT_STATUS); \
        printf "  ...glide up..."; \
            cd $(BASEDIR); \
            $(GLIDE) up $(MAKE_LOG_FD); \
            $(PRINT_STATUS); \
        printf "  ...go get..."; \
            go get -d $(GOFLAGS) $(NV); \
            $(PRINT_STATUS); \
    fi

[akutz]

Hi @mattfarina,

Ah, thanks for the response. Yes, I had to do something similar in Gomk for go vet as that tool did not function correctly when using an OS/ARCH separate from the host.

[akutz]

FWIW, I think option number two makes the most sense.

[mattfarina]

@akutz I'm thinking of handling both options. Appengine is an annoying special case and the flag would be useful.

[akutz]

Why is Appengine so annoying? Just curious. Because it's on Github but has import path from Google?

[mattfarina]

The appengine import is appengine and not a remote location. It's a special case build mode for appengine where the SDK (import of appengine) is available in the same way standard library packages are. It's a special case where two Google products (appengine and Go) are colluding in a non-standard way.

[akutz]

Ruxin from the League agrees :)

[mattfarina]

This should now be fixed. If not please re-open the issue.

[akutz]

Hi @mattfarina,

So it failed on Travis again. https://travis-ci.org/emccode/rexray/builds/110459662

However, it worked locally when I updated Glide. I am resending my commit to Travis instead of just rerunning the build in case Travis had cached the Glide sources. I don't tell it to, but I don't know another explanation.

[akutz]

Nope, still failing - https://travis-ci.org/emccode/rexray/builds/110483778. I just nuked my local vendor dir and am trying a full glide up again locally to see if the reason it worked locally earlier was from caching.

[akutz]

Hi @mattfarina,

It's failing locally. The reason it worked was because I had not actually upgraded Glide to 0.9 locally. I neglected the -u flag in go get. I just used it to upgrade to the tip of master, and it's failing locally as well.

[akutz]

I'm an idiot. Didn't realize just added the flag. Thought you were also handling appengine as a special case. The flag works :)

[mattfarina]

I seem to have missed an app engine specific package.

[mattfarina]

@akutz this "should" now be fixed and I tested against rexray.
