Gas Estimation: tests dont work with ganache-cli@6.4.2 and later

[shanefontaine]

Running any version of ganache-cli >=6.4.2 (Gas Exactimation) breaks tests on this repository. In reviewing the ganache-cli@6.4.2 changelog, I read to submit an issue here if an OOG error is experienced.

Expected Behavior

By following the "Test" section of the README, I expect all tests to run successfully (with npm run test). This is what happens prior to ganache-cli@6.4.2.

To run ganache-cli, I am not using the npm script, but rather using ganache-cli -p 8545 -m "asset member awake bring mosquito lab sustain muscle elephant equip someone obvious" -a 100

Current Behavior

error=Error: Returned error: VM Exception while processing transaction: out of gas

ganache-cli versions 6.4.2, 6.4.3, and 6.4.4 produce the above error when running npm run test.

Steps to Reproduce (for bugs)

# Install Ganache-cli globally:
npm install --global ganache-cli

# Install Truffle globally:
npm install --global truffle@v4.1.12

# Install local node dependencies:
npm install

# Compile contracts
npm run compile

# Run ganache-cli
ganache-cli -p 8545 -m "asset member awake bring mosquito lab sustain muscle elephant equip someone obvious" -a 100

# Run contracts test suite
npm run test

Context

This was discovered when running tests on this repository.

Your Environment

• truffle@4.1.12

Hey there @shanefontaine! Thanks for opening this issue!

I just released a new beta with a gas estimation fix a few minutes ago! I haven't even published the release notes yet!

Do you mind trying it out and letting me know if it fix the issue for you?

To update to the beta run:
npm install --global ganache-cli@beta

[shanefontaine]

Great timing. This beta version works perfectly. I'll go ahead and close this issue.

@davidmurdoch is there going to be any note or warning on 6.4.2-6.4.4 that says that there may have been a breaking change in these versions? Or will this fix be included in a major semantic change soon? I am wondering if there are any other people that have run into this issue and have not read the one line in the Changelog.

[davidmurdoch]

This wasn't a breaking change (at least not in the semver definition of "breaking"). This was a regression/bug. The next patch release will fix this bug.

[shanefontaine]

That makes sense. Thank you.
