test_eof_on_empty_read()

static void test_eof_on_empty_read ( void  )

static

EOF is signalled even when the read which notices it returns no data.

The pipe used to call read_blocked() in that case, telling an application which read until it got nothing that it was blocked rather than finished.

test_eof_walk_continues()

static void test_eof_walk_continues ( void  )

static

An empty pipe must not stop the EOF walk.

fr_bio_eof() stops when a handler returns zero or less. The pipe used to return zero for "nothing buffered", which stopped the walk and left a chain containing a pipe unable to finish.
