The tests that would have help avoid bug #73948 and all that mess :)

* bzrlib/transport/http/response.py:
(handle_response): Translate a 416 http error code into a bzr
exception.

* bzrlib/transport/http/_urllib2_wrappers.py:
(HTTPDefaultErrorHandler.http_error_default): Translate a 416 http
error code into a bzr exception.

* bzrlib/transport/http/_pycurl.py:
(PyCurlTransport._curl_perform): It could happen that pycrul
itself detect a short read.

* bzrlib/transport/http/__init__.py:
(HttpTransportBase._retry_get): New method, factorizing the retry
logic.
(HttpTransportBase.readv): We can have exception during the
initial GET worth degrading the range requirements (i.e. retrying
the GET request with either single or not ranges).

* bzrlib/tests/test_transport_implementations.py:
(TransportTests.test_readv_short_read): InvalidRange can also be
raised.

* bzrlib/tests/test_http.py:
(TestRangeRequestServer.test_readv_invalid_ranges): Was named
test_readv_short_read, the new name make the intent
clearer. Depending of the code path used (urllib or pycurl), both
exceptions can be raised.

* bzrlib/tests/HttpServer.py:
(TestingHTTPRequestHandler.do_GET): If invalid ranges are
specified, returns a 416 instead of the whole file (both are valid
according to the RFC).

Broadly tries to ascribe parts of the tree state to individual commits.
5
 
 
6
 
There appear to be three basic ways of generating annotations:
7
 
 
8
 
If the annotation works by asking the storage layer for successive full texts
9
 
then the scaling of this will be proportional to the time to diff throughout
10
 
the history of thing being annotated.
11
 
 
12
 
If the annotation works by asking the storage layer for successive deltas
13
 
within the history of the thing being annotated we believe we can make it scale
14
 
broadly proportional to the depth of the tree of revisions of the annotated
15
 
object.
16
 
 
17
 
If the annotation works by combining cached annotations such that creating a
18
 
full text recreates annotations for it then it will scale with the cost of
19
 
obtaining that text.
20
 
 
21
 
Generally we want our current annotations but it would be nice to be able to do
22
 
whitespace annotations and potentially other diff based annotations.
23
 
 
24
 
Some things to think about:
25
 
 
26
 
 * Perhaps multiparent deltas would allow us to not store the cached
27
 
   annotations in each delta without losing performance or accuracy.
