Hi,
In SMBTransport there is the following code fragment
/* out of phase maybe? */
/* inch forward 1 byte and try again */
for (int i = 0; i < 35; i++) {
sbuf[i] = sbuf[i + 1];
}
int b;
if ((b = in.read()) == -1) return null;
sbuf[35] = (byte)b;
which maybe can be replaced by
/* out of phase maybe? */
/* inch forward 1 byte and try again */
if (log.level >= 5) {
log.println( "maybe we are out of phase. Try resyncing" );
}
System.arraycopy( sbuf, 1, sbuf, 0, 35 );
if (log.level >= 6) {
jcifs.util.Hexdump.hexdump( log, sbuf, 4, 31 );
}
if (readn( in, sbuf, 35, 1 ) == -1) {
return null;
}
Is "out of phase" an often case? There is some more improvement possible
thought searching next possible resync point in the avaiable 35 bytes! I
can try to create the improvement, or is this code only used very rare?
