A while back, for performance reasons, we disabled yielding for all files.* operations unless METEOR_DISABLE_FS_FIBERS was set to false. This was safe for almost all files.* operations, because most of them have a synchronous fs.*Sync version available. For a more complicated operation like files.rm_recursive, however, there is no synchronous or asynchronous counterpart in the fs.* namespace, so the safety of disabling fibers is not guaranteed. Lately, files.rm_recursive has become a major source of uncaught ENOTEMPTY errors on Windows, because rimraf.sync fails with that error, and we don't give files.rm_recursive_async a chance to delete the directory in a more persistent, forgiving manner. The only reason we haven't been falling back to files.rm_recursive_async is that YIELD_ALLOWED is false by default, so canYield() returns false. This commit distinguishes between canYield() and mayYield(), and uses canYield() in files.rm_recursive to determine whether it is technically safe to yield, regardless of YIELD_ALLOWED. Anyone who ever asked "Can I go to the bathroom?" in elementary school, only to be mercilessly rebuked with "I don't know, CAN YOU?" should understand the difference between these two functions.
Meteor is an ultra-simple environment for building modern web applications.
