4c8408b42d Print reason for failure to connect headers 
Used to fail just with a "header didn't connect" message, now
it gives a reason too.

ec9cdfaf48 blockchain: restore call to set_local_height, forgotten in previous commit 2015-06-13 16:45:42 +02:00
Neil Booth
d16714a1db Make the blockchain class not a thread 
Remove interface communication out of blockchain.py
into network.py.  network.py handles protocol requests
for headers and chunks.  blockchain.py continues to
handle their analysis and verification.

If an interface provides a header chain that doesn't
connect, it is dismissed, as per a previous TODO comment.

This removes a thread and another source of timeouts.
I see no performance issues with this when truncating the
blockchain.

Rename 'result' to 'header' for clarity.

233fd8ed77 revert 175bfae9e6. store last known height in wallet instead 2015-05-08 13:43:42 +02:00
Neil Booth
175bfae9e6 Move away from requiring network and blockchain objects to be able to request local height. 
We store it in the config object instead of in the blockchain object.
The blockchain object now refers to its config, and calls refresh_height() to update it.
The network objects also refer to the config rather than the blockchain.

This is the first of many small steps to untangle the verifier from stored state and so
permit the history tab to work in offline mode.  The refactoring will simultaneously clean
up a lot of accumulated cruft.

discuss this ad nauseam):
