How to Reproduce this test

• Set up a bucket with google cloud storage, and put the .tar file there.

• In index.js, set FILENAME to the name of the tar, and BUCKET to the name of the bucket.

• In index.js, add a exports.<functionName> function handler. My functionName was RUNTIMETEST

• Deploy the cloud function. I did this by linking my mirroring my github repo to google cloud and running the following command on my terminal. gcloud beta functions deploy RUNTIMETEST --source-url https://source.developers.google.com/p/pywrenTest/r/pytest --source-path / --trigger-bucket allanpeng11231994storage

• source-url is the link to the repo with the format https://source.developers.google.com/p/<PROJECT_NAME>/r/<REPO_NAME>

• --source-path is the location of the function file in the repo directory.

• trigger-bucket refers to the bucket whose events will trigger the function.

Running the function

To run the function, upload a blank file to the trigger bucket.

touch test.txt && gsutil cp test.txt gs://allanpeng11231994storage

To view the output, execute gcloud beta functions logs read --limit 10 in the terminal.

Notes

May need to increase memory allocation through google cloud console. Also increase the alloted time or else it'll time out after 1 minute.

The runtime I'm using is over 300MB, and GCF defaults to 256MB, so it will kill your function if you don't raise it.

For some reason, child_process.execSync always crashes. I'm not sure if this is because i'm calling it incorrectly, but child_process.spawn works fine.
