Follow up to #19079, which made test names fully qualified.
This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit:
"priority_queue.test.std.PriorityQueue: shrinkAndFree"
and the same test's name after the changes in this commit:
"priority_queue.test.shrinkAndFree"
BufferedTee provides reader interface to the consumer. Data read by consumer
is also written to the output. Output is hold lookahead_size bytes behind
consumer. Allowing consumer to put back some bytes to be read again. On flush
all consumed bytes are flushed to the output.
input -> tee -> consumer
|
output
input - underlying unbuffered reader
output - writer, receives data read by consumer
consumer - uses provided reader interface
If lookahead_size is zero output always has same bytes as consumer.
