Another option is to send a patch upstream that fixes the benchmark but that takes a lot more time. |
deps/v8/benchmarks/regexp.js clobbers the RegExp global, breaking
util.format() and console.log(). Unclobber it to keep the other
benchmarks working.
Fixes the following error when running benchmark/misc/v8-bench.js:
$ out/Release/iojs benchmark/misc/v8-bench.js
util.js:84
if (new RegExp('\\b' + set + '\\b', 'i').test(debugEnviron)) {
^
TypeError: object is not a function
at Object.exports.debuglog (util.js:84:9)
at timers.js:12:29
at NativeModule.compile (node.js:800:5)
at NativeModule.require (node.js:769:18)
at net.js:5:14

at tty.js:4:11

at Function.NativeModule.require (node.js:769:18)
This could alternatively be addressed by caching the RegExp global
in lib/util.js. That's not a bad approach and I considered it but
doing it for just RegExp and not other globals would be half-baked.
Maybe the more thorough approach where we cache all globals at
start-up is something for a follow-up pull request.
