tests: output into tmp2 directory #483

Closed pjonsson closed 4 years ago

pjonsson commented 4 years ago

This restores the execution time for running 'stack test' with VSCode running to the same time as running 'stack test' without it.

The problem turned out to be the MS C/C++ IntelliSense plugin and file watching. Our tests output C files in the test directory at a rapid pace which causes IntelliSense to react to the new files and use the CPU for non-test related activities.

The best case scenario would be to output our tests into a temporary directory somewhere but this is the minimal fix that I can get sane performance with. I still have this in my settings.json:

"files.watcherExclude": {
    "**/.git": true,
    "**/.DS_Store": true,
    "**/tmp" : true,
    "**/tmp2" : true,
    "**/.stack-work" : true,
},
"files.exclude": {
    "**/.git": true,
    "tmp" : true,
    "tmp2" : true,
    ".stack-work" : true,
},
