Subject: [PATCH] evbuffer_add: Use last_with_datap if set, not last.
|
|
|
|
evbuffer_add() would always put data in the last chain, even if there
|
|
was available space in a previous chain, and in doing so it also
|
|
failed to update last_with_datap, causing subsequent calls to other
|
|
functions that do look at last_with_datap to add data in the middle
|
|
of the evbuffer instead of at the end.
|
|
|
|
Fixes the evbuffer_add() part of issue #335, and the evbuffer/add2 and
|
|
evbuffer/add3 tests, and also prevents wasting space available in the
|
|
chain pointed to by last_with_datap.
