In 5ab6419: What is the rationale of the range 150~15000?
There was a problem hiding this comment.
I tried to pick a range large enough for randomization to be efficient, but the range itself is arbitrary and could be adjusted.

For more clarification @brunoerg the 150 starting point was chosen in the previous test to exclude the genesis block iiuc. The 15000 range should be large enough to provide efficient randomization but small enough to not end outside of the blockfile (200 blocks in the test with ~160 characters each). Could also shorten or enlarge the range ((200*160 = 32000 characters) but I thought 15000 would a good middle ground.
Let me know if you have any suggestions. Can also add a line of documentation if necessary.

Concept ACK, better if someone else does a full review though since part of the changes are from me |

Light ACK 5ab6419 The refactoring changes in the first commit look correct and randomizing offset/size of the perturbation data seems to be an improvement for discovering more issues. Can't say much about the concrete random ranges chosen though, it might make sense to have someone review this that has more insight into the file format or specific cases that were in mind to be triggered (on the other hand, perfect is the enemy of good...). |
