We now have a log message removed, was that intended?

Nice catch! Fixed.

This test script verifies pulls every time they are updated. It, however, dies sometimes and fails to test properly.

This seems pretty useful. Looks okay, I'll give it some testing.
laanwj commented at 7:58 AM on October 9, 2014: member

I've been testing this as well.
rdponticelli commented at 9:54 AM on October 9, 2014: contributor

I've been reviewing and testing as well, building on top #4701 and #4468. So far, so good. So for me it would be an ACK.

laanwj commented at 9:09 AM on October 16, 2014:

I wonder; do we need this (conditional) resize in three places, or could we replace it with an assert in some of the places because encountering a new block file would be unexpected?

rdponticelli commented at 8:27 PM on October 20, 2014:

Yeah, I've been thinking about those repetitions as well. But I think there are other improvements to make into how block files are managed, so some of those improvements might well be left for latter pulls.

Tested ACK (has run succesfully on some of my test nodes for a while; survived a succesful reindex)

Suggestion: You could also switch over to use func instead of the function name :).

sipa commented at 11:18 PM on October 21, 2014:

Done.
