2018-07-04Merge #13575: Refactor: Rename NET_TOR to NET_ONIONWladimir J. van der Laan
07c493f2d scripted-diff: Replace NET_TOR with NET_ONION (wodry) Pull request description: This is a follow-up to #13532, where @promag already asked if this renaming would make sense. If network shall be named _Onion_ instead of _Tor_ (like in the option `onlynet`), renaming the network enum NET_TOR to NET_ONION maybe would make sense and be stringent. Change was produced with the following script: ``` #!/bin/bash for file in $(grep --exclude-dir='.git' --files-with-matches --binary-files=without-match --recursive NET_TOR bitcoin/) do sed --in-place --expression='s/NET_TOR/NET_ONION/g' $file done ``` _Tor_ is used at many other places in the code, though.

Add unit tests for them. * In https://github.com/bitcoin/bitcoin/pull/13142#issuecomment-386396975 it was suggested to merge `isInvalid` into the return status. This PR takes a different approach, and removes the `isInvalid` entirely. It was only ever used inside tests, as normal users of IsMine don't care about the reason for non-mine-ness, only whether it is or not. As the unit tests are extensive enough, it seems sufficient to have a black box text (with tests for both compressed and uncompressed keys). Some addition code simplification is done as well.

(Matt Corallo) Pull request description: Originally this PR was just to add tests around concurrency in block validation - those tests seem to have uncovered another bug in ActivateBestChain - this now fixes that bug and adds tests. ActivateBestChain (invoked after a new block is validated) proceeds in steps - acquiring and releasing cs_main while incrementally disconnecting and connecting blocks to sync to the most work chain known (FindMostWorkChain()). Every time cs_main is released the result of FindMostWorkChain() can change - but currently that value is cached across acquisitions of cs_main and only refreshed when an invalid chain is explored. It needs to be refreshed every time cs_main is reacquired. The test added in https://github.com/bitcoin/bitcoin/pull/13023/commits/6094ce73045fe0b4654ff94327c2059512af88fb will occasionally fail without the commit fixing this issue https://github.com/bitcoin/bitcoin/pull/13023/commits/26bfdbaddbb9f13864deb7241c6d513f22c5ab62 Original description below -- After a bug discovered where UpdatedBlockTip() notifications could be triggered out of order (#12978), these unit tests check certain invariants about these signals. The scheduler test asserts that a SingleThreadedSchedulerClient processes callbacks fully and sequentially. The block validation test generates a random chain and calls ProcessNewBlock from multiple threads at random and in parallel. ValidationInterface callbacks verify that the ordering of BlockConnected BlockDisconnected and UpdatedBlockTip events occur as expected.

This ensures that the `scriptCode` serialized in `SignatureHash` is always the same as the script passing to the `EvalScript`.

Silently converting to a CMutableTransaction will drop all caches and should thus be done explicitly

Tests showing that CONST_SCRIPTCODE is applied only to non-segwit transactions

This disables OP_CODESEPARATOR in non-segwit scripts (even in an unexecuted branch), and makes a positive FindAndDelete result invalid. This ensures that the scriptCode serialized in SignatureHash() is always the same as the script passing to the EvalScript.
