That's good! > However, there are a whole bunch of IntegerModRings still around. Like this? sage: import gc sage: gc.collect() 662 sage: p = 1 sage: for i in range(100): ....: p = next_prime(p) ....: R = ZZ.quotient(p) ....: x = 1+R.one() ....: _ = gc.collect() ....: print len([X for X in gc.get_objects() if isinstance(X, sage.rings.finite_rings.integer_mod_ring.IntegerModRing_generic)]), ....: 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 Note that this only happens if the line "x = 1+R.one()" is present. Without that line, the number of IntegerModRing_generic in cache remains constantly 2 (if one has my patches applied, at least...). In other words: It *is* a memory leak caused by coercion, but it isn't covered by my patches (yet).
