1 Test that uvcount=0 resources are correctly freed when reached via a 2 GC sweep. The script builds a self-referential cycle holding a pipe 3 (whose io.handle resources are uvcount=0) and forces a collection; 4 under the bug the io.handle structs are leaked on every `gc()` call. 5 6 This test depends on running under a leak detector. 7 8 -- Testcase -- 9 {% 10 import * as io from 'io'; 11 import { stdout } from 'fs'; 12 13 for (let i = 0; i < 3; i++) { 14 let cycle = []; 15 cycle[0] = cycle; 16 cycle[1] = io.pipe(); 17 cycle = null; 18 gc("collect"); 19 } 20 21 print("ok\n"); 22 stdout.flush(); 23 %} 24 -- End -- 25 26 -- Expect stdout -- 27 ok 28 -- End --
