| Summary | 0002641: Unusual number reported to statistics by datacache for "bytes stored" | ||||
| Description | gnunet-statistics shows unusually big number for the number of bytes stored harsha@nautophone:~/repos/sree-testbed$ gnunet-statistics -s datacache datacache # bytes stored: 695785550805 | ||||
| Steps To Reproduce | start peer wait for 10~20 min gnunet-statistics -s datacache | ||||
| Tags | No tags attached. | ||||
| Attached Files | |||||
| I cannot reproduce this. Can you please run your peer with $ gnunet-statistics -s datacache -n "# bytes stored" -w running at the same time so I might get a glance as to what is going on? | |
| Attached a file containing the output. The counter increases by a large value in line 1476. | |
| Ah, that's an increase by "-1672" mod uint32... | |
| Here it is (datacache.c:117): size_t size; // ... GNUNET_STATISTICS_update (h->stats, gettext_noop ("# bytes stored"), -size, GNUNET_NO); On my system, size_t is a 64-bit value, so "- size == size", but then the cast to a "long long" (update takes a *signed* value) makes everything OK. On your system, size_t is a 32-bit value, so "- size" = UINT32_MAX - size, and then the (implicit) cast to "long long" does nothing, and you jump almost +4GB. | |
