(Matt Corallo) Pull request description: This should make it easier to debug issues where the CheckBlock at the top of ProcessNewBlock fails (which does not print, in contrast to AcceptBlock, which always prints). This was motivated by #11371 which appears to be exactly such a case, and is not debuggable from the information provided. Not sure how much this would have helped in that case, but it is kinda weird that we can reject a block without ever printing why.

2017-09-15Trivial: Fix validation commentsDan Raviv
- Move comment about transaction/block weight calculation so it applies not only to the GetBlockWeight function but also to GetTransactionWeight - Fix comment in validation.cpp referencing future deployment of BIP113. It has already been deployed. - The doc comment for BLOCK_DOWNLOAD_WINDOW wasn't updated since pruning was introduced, so it still refers to pruning as something that might happen in the future. A larger BLOCK_DOWNLOAD_WINDOW window would now, indeed, make pruning harder.

This should have always been the case, but we will correctly trim to size after a reorg which is when bypass_limits is set.
2017-09-12Change AcceptToMemoryPool function signatureAlex Morcos
Combine fLimitFree and fOverrideMempoolLimit into a single boolean: bypass_limits. This is used to indicate that mempool limiting based on feerate should be bypassed. It is used when readding transactions from a reorg and then the mempool is trimmed to size after all transactions are added and they can be evaluated in the context of their descendants. No changes to behavior.

2017-07-14Remove confusing MAX_BLOCK_BASE_SIZE.Gregory Maxwell
Some people keep thinking that MAX_BLOCK_BASE_SIZE is a separate size limit from the weight limit when it fact it is superfluous, and used in early tests before the witness data has been validated or just to compute worst case sizes. The size checks that use it would not behave any differently consensus wise if they were eliminated completely. Its correct value is not independently settable but is a function of the weight limit and weight formula. This patch just eliminates it and uses the scale factor as required to compute the worse case constants. It also moves the weight factor out of primitives into consensus, which is a more logical place for it.
