Sebb created IO-335:
-----------------------
Summary: Tailer#readLines - incorrect CR handling
Key: IO-335
URL: https://issues.apache.org/jira/browse/IO-335
Project: Commons IO
Issue Type: Bug
Reporter: Sebb
The readLines method checks for CR. If found, it is not stored immediately, but
a flag is set.
If the next char is an LF, the buffer is passed to the listener without the CR.
As soon as the next non-LF (and non-CR) character is received, the saved CR is
written to the buffer.
The net result is that CR before LF migrates to the start of the next non-empty
line, and repeated CRs are collapsed. This is clearly wrong.
The original code (before IO-274) used RandomAccessFile#readLine() which
returns on CR, LF or CRLF.
It looks as though the intention was to retain this behaviour whilst not
blocking.
