observations

From some point on the main branch, tests on Mac in CI started to fail continuously. The logs tell us almost nothing but the exit code:

saying:

> npm run lint
Error: Process completed with exit code 249.

Above npm run lint is pretest script that runs before test script. So I removed pretest script to skip lint. But CI is still reporting the same error:

> node ./test/runTest.js
Error: Process completed with exit code 249.

Above node ./test/runTest.js is test script.
Then, I guessed that maybe the big package.json was the cause, so I removed all the keybindings definitions in the package.json to find out the cause.
Then, the error disappeared.

observations part 2

Based on the hypothesis that the large package.json is the cause, I tried a binary search.

In summary, roughly 220KB of package.json is ok, but 227KB of package.json is not.

% of keybindings included	size of package.json	test
0%	4,673	pass
50%	121,358	pass
75%	179,733	pass
87%	206,426	pass
94%	220,638	pass
97%	227,328	fail
100%	234,242	fail

All these failures are the 'exit code 249'.
