when I use null-transform plugin and print some debug info, I find the
TSVIONTodoGet() return a huge member, I consider it maybe has a bug !
The details shows below:
code in null-transform.c:
TSVIO input_vio;
int64_t towrite = 0;
int64_t avail = 0;
towrite = TSVIONTodoGet(input_vio);
TSDebug("null-transform", "\ttoWrite is %" PRId64 "", towrite);
if (towrite > 0) {
/* The amount of data left to read needs to be truncated by
* the amount of data actually in the read buffer.
*/
avail = TSIOBufferReaderAvail(TSVIOReaderGet(input_vio));
TSDebug("null-transform", "\tavail is %" PRId64 "", avail);
#if MDSN_LOG
if (log) {
TSTextLogObjectWrite(log, "handle_transform() with data to
write length: %" PRId64 ", IOBufferReader available data length: %" PRId64 "",
towrite, avail);}
#endif
log info:
20110818.13h51m11s handle_transform() with data to write length:
9223372036854775807, IOBufferReader available data length: 1388
