Wallaby hanging

[zpydee]

Issue description or question

Hi,

I've got a node project and node has started hanging, this is the first excerpt from the walaby console:

[Info] Started Wallaby.js Core v1.0.282
[Error] Error: spawn /Users/zpydee/.nvm/versions/node/v6.3.0/bin/node EMFILE
[Error]   at exports._errnoException (util.js:1008:11)
[Error]   at Process.ChildProcess._handle.onexit (internal/child_process.js:182:32)
[Error]   at onErrorNT (internal/child_process.js:348:16)
[Error]   at _combinedTickCallback (internal/process/next_tick.js:74:11)
[Error]   at process._tickCallback (internal/process/next_tick.js:98:9)

The process eventually runs out of memory after several attempts.

I've recently added the following before_install to my .travis.yml file to prevent travis from not being able to run a post-install on nested package.json files and not sure if this could be causing the EMFILE:

before_install:
  - PATH=${PATH//:\.\/node_modules\/\.bin/}

Any guidance would be greatly appreciated. My tests are passing in mocha.

thanks,
Dave

I'm not sure if it's wallaby specific issue, have you seen/tried this: sindresorhus/gulp-imagemin#10 (comment)?

[ArtemGovorov]

Actually this is probably be more helpful as from what I read ulimit is only the the current terminal session.

[zpydee]

hmmmm, increasing ulimit no helping

[ArtemGovorov]

Looks like ulimit is only the the current terminal session, did you try the suggestion from this answer? Also, perhaps try killing all node processes/rebooting to see if it helps.

[zpydee]

issue actually seems related to my post-install script somehow:

"postinstall" : "find ./src/* -maxdepth 5 -name package.json -execdir npm install \\;",

its still running, but if I set it lower than 5, it runs happily but the wallaby can't find lib dependencies for child projects..

i'll keep on investigating, but i'm gonna close this issue for now...

[ArtemGovorov]

Thanks for the update, perhaps this could help for resolving dependencies for child projects: https://wallabyjs.com/docs/integration/node.html#node-modules-in-subfolder

[zpydee]

thanks, that suggestion was on the money - happy to have my coloured dots back :-)

just for sake of clarity, I added:

process.env.NODE_PATH += path.delimiter + path.join(w.localProjectDir, 'src/lib/utils/encryption', 'node_modules');

to point to my encryption library. am I correct in assuming I'd repeat for each child project that has its own node_modules?

[ArtemGovorov]

am I correct in assuming I'd repeat for each child project that has its own node_modules?

Correct. This, or, given that wallaby config is essentially a node app, you can write a small function to recursively walk your folder structure and add found node_modules folders to the process.env.NODE_PATH automatically (may make sense if you have a lot of child projects).

[zpydee]

thanks as always for your prompt and very helpful assistance!
