Package: libnanohttp1
Version: 1.1.0-14
Severity: normal
Currently the code has no timeout on the http connection. It has a timeout
on read operations that defaults to 10 seconds (and can be set to other
values). If a server is offline and packets are being dropped then the
kernel TCP timeout applies and that takes 189 seconds on my Lenny system -
which is generally longer than desired on modern networks.
The following patch makes the timeout that is used for reads also apply to
connect.
