Spawn go daemon does not work with Node.js v9.9.0+

[alanshaw]

.spawn never calls back.

We're already testing js-ipfsd-ctl on nodejs 9.2.0. Is there a specific version you're thinking about?

[alanshaw]

Possibly, I'm on 9.10.0. I'll add a reproducible example when I get a sec.

[victorb]

I see. I added a test-run with 9.10.0 activated (together with the old ones we're already running): https://ci.ipfs.team/blue/organizations/jenkins/IPFS%2Fjs-ipfsd-ctl/detail/master/40/pipeline/

[victorb]

Nevermind, test with just 9.10.0: https://ci.ipfs.team/blue/organizations/jenkins/IPFS%2Fjs-ipfsd-ctl/detail/master/41/pipeline

[victorb]

On Jenkins (linux at least), the node-gyp builds are not even working properly: https://ci.ipfs.team/blue/organizations/jenkins/IPFS%2Fjs-ipfsd-ctl/detail/master/41/pipeline/13

[dryajov]

Taking a look now as well.

BTW - everything up until 9.8.0 seems to work as expected (I'm on 9.0.0 myself), v9.10.0 is pretty broken.

This is probably related to jbenet/node-subcomandante#6

[travisperson]

We just published v1.2.0 for node-subcomandante, which should fix this issue. I ran the tests locally, but am running into what I believe is a type check issue when running js-ipfs in proc.

Package [email protected] wants ipfs-repo@^0.19.0
 from .
 resolves to ./node_modules/[email protected]

Package [email protected] wants ipfs-block@~0.7.1

Package [email protected] wants ipfs-repo@~0.18.7
 from ./node_modules/ipfs
 resolves to ./node_modules/ipfs/node_modules/[email protected]

Package [email protected] wants ipfs-block@~0.6.1

 resolves to ./node_modules/[email protected]

Package [email protected] wants ipfs-block@~0.6.1
 from ./node_modules/ipfs
 resolves to ./node_modules/[email protected]

This resolves down into:

• ipfsd-ctl wants [email protected], and ipfs wants [email protected],
• [email protected] uses [email protected]
• [email protected] uses [email protected]

Both of these packages check blocks differently, so they are not compatible.

Downgrading the ipfs-repo dependency of ipfsd-ctl to [email protected] fixes the issue and all tests now pass on Node.js v9.9.0!

[dryajov]

Weird this would show only under v9.9.0? I've seen the block error pop up with previous versions. Does using the correct dependencies (npm link?) fix the issue as well?

[travisperson]

Weird this would show only under v9.9.0?

Sorry if this was confusing. The block error has nothing to do with Node.js v9.9.0 or node-subcomandante, I'm just unable to verify that the newly published version of node-subcomandante works in master due to the block issue without downgrading the dependency ipfs-repo.

Everything works correctly in Node.js v9.9.0 if I downgrade ipfs-repo to a compatible version that works with the js-ipfs dependency (v0.28.2).

[dryajov]

@travisperson oh! Got you, thanks for clarifying - this makes sense then 👍

@alanshaw can i close this? jenkins is running node 10 and tests are passing
