Is File#print atomic when given multiple arguments?
F开发者_JS百科or C-based implementations of ruby 1.8 and ruby 1.9, is File#print
atomic when it is given multiple arguments?
Examining it empirically, the answer's no.
10.times do
Thread.new do
print "foo", "\n"
end
end
gives (in ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0])
foofoofoo
foo
foo
foo
foo
foo
foo
foo
Don't know where you can look up what is atomic and what isn't atomic, though.
