"""Tests from HTTP response parsing.
19
The handle_response method read the response body of a GET request an returns
20
the corresponding RangeFile.
22
There are four different kinds of RangeFile:
23
- a whole file whose size is unknown, seen as a simple byte stream,
24
- a whole file whose size is known, we can't read past its end,
25
- a single range file, a part of a file with a start and a size,
26
- a multiple range file, several consecutive parts with known start offset
29
Some properties are common to all kinds:
30
- seek can only be forward (its really a socket underneath),
31
- read can't cross ranges,
32
- successive ranges are taken into account transparently,
34
- the expected pattern of use is either seek(offset)+read(size) or a single
35
read with no size specified. For multiple range files, multiple read() will
36
return the corresponding ranges, trying to read further will raise
