In the osmo-bts and libosmo-abis code the hexdump routine is used
for every incoming/outgoing packet (including voice frames) and the
usage of snprintf showed up inside profiles.
There is a semantic change when more than 4096 characters are used.
The code will now truncate at byte boundaries (and not nibbles).
Code:
static const int lengths[] = { 23, 1000, 52 };
char buf[4096];
int i;
for (i = 0; i < 30000; ++i)
char *res = osmo_hexdump(buf, lengths[i & 3]);
Results:
before: after:
real 0m3.233s real 0m0.085s
user 0m3.212s user 0m0.084s
sys 0m0.000s sys 0m0.000s
