Merge #12904: [qa] Ensure bitcoind processes are cleaned up when tests end
e36a0c0 [qa] Ensure bitcoind processes are cleaned up when tests end (Suhas Daftuar)

Pull request description:

  When tests fail (such as due to a bug in the test, race condition, etc), it's possible that we could follow code paths that bypass our normal node shutdown that occurs in `TestNode.stop_node`.  Add a destructor to `TestNode` that cleans this up.

Merge #12843: [tests] Test starting bitcoind with -h and -version
63048ec73d [tests] Test starting bitcoind with -h and -version (John Newbery)

Pull request description:

  Test that starting bitcoind/bitcoin-qt with `-h` and `-version` works as expected.

  Prompted by https://github.com/bitcoin/bitcoin/pull/10762#commitcomment-28345993, which is a nullpointer dereference triggered by starting bitcoin-qt with `-h`.

  On master, this test passes when run over bitcoind, but fails when running over bitcoin-qt. I used xvfb as a virtual frame buffer to test:

  ```

  ```

  Passes for bitcoind and bitcoin-qt when run on #12836.

  Longer term, we should consider running functional tests over bitcoin-qt in one of the Travis jobs.

  This is prompted by and builds on #12545, a nice cleanup / consolidation of patterns.

  In cases where the exception message was meaningful, I tried to represent it as well in a comment.

  I expect #12545 will go in first, but I'm happy to squash them if that's preferred.

Merge #12486: [test] Round target fee to 8 decimals in assert_fee_amount
42e1b5d [test] Round target fee to 8 decimals in assert_fee_amount (Karl-Johan Alm)

Pull request description:

  The output would produce arbitrary number of decimal points, sometimes resulting in 9 decimals:
  ```
  AssertionError: Fee of 0.00000415 BTC too low! (Should be 0.000006175 BTC)

  The above looks like the expected fee is 6175 sats when in reality it's 618.

faab63111d8f27335aa1f09c1a48da3be45135de shutdown: Stop threads before resetting ptrs (MarcoFalke)

Pull request description:

  On shutdown some threads would continue to run after or during a pointer reset. This leads to occasional segfaults on shutdown.

  Fix this by resetting the smart pointers after all threads that might read from them have been stopped.

  This should fix:
  * A segfault in the txindex thread, that occurs when the txindex destructor is done, but the thread was not yet stopped (as this is done in the base index destructor)
  * A segfault in the scheduler thread, which dereferences conman. (e.g. CheckForStaleTipAndEvictPeers)

Fix issues introduced with asynchronous signal handling (#3369)
* Introduce SynchronousUpdatedBlockTip signal

This version of UpdatedBlockTip mirrors the asynchronous behavior that we
had before the introduction of asynchronous signal handling.

* Fix tab spacing in validationinterface.cpp

* Invoke CDeterministicMNManager::UpdatedBlockTip from validation thread

It must be invoked synchronously as otherwise things become inconsistent.

* Call CActiveMasternodeManager::Init with block index

pindexNew in UpdatedBlockTip is not necessarily the current tip, so we
shouldn't rely on it in Init(). This is due to the async nature of the
UpdatedBlockTip invocation.

Merge #11309: Minor cleanups for AcceptToMemoryPool
bf64c3cb3 Ignore transactions added to mempool during a reorg for fee estimation purposes. (Alex Morcos)
04f78ab5b Do not reject based on mempool min fee when bypass_limits is set. (Alex Morcos)
fd849e1b0 Change AcceptToMemoryPool function signature (Alex Morcos)

Pull request description:

  First commit just removes default arguments from `AcceptToMemoryPool` and consolidates two arguments, it does not change behavior.

  Second commit finally fixes the fact that we're not meant to reject based on mempool min fee when adding a transaction from a disconnected block during a reorg as mentioned [here](https://github.com/bitcoin/bitcoin/pull/9602#issue-202197849)

  Third commit makes fee estimation ignore transactions added from a disconnected block during a reorg. I think this was another source of fee estimates returning estimates below 1000 sat/kB as in #11303.

  This change (currently) avoids loading the mempool if shutdown is requested.

Merge #12401: Reset pblocktree before deleting LevelDB file
a8b5d20 Reset pblocktree before deleting LevelDB file (Sjors Provoost)

Pull request description:

  #11043 repaced:

  ```
  delete pblocktree;
  pblocktree = new CBlockTreeDB(nBlockTreeDBCache, false, fReset);
  ```

  With:

  ```
  pblocktree.reset(new CBlockTreeDB(nBlockTreeDBCache, false, fReset));
  ```

  This is problematic because `new CBlockTreeDB` tries to delete the existing file, which will fail with `LOCK: already held by process` if it's still open. That's the case for QT.

  When QT finds a problem with the index it will ask the user if they want to reindex. At that point it has already opened `blocks/index`.  It then runs this [while loop](https://github.com/bitcoin/bitcoin/blob/v0.16.0rc3/src/init.cpp#L1415) again with `fReset = 1`, resulting in the above error.

  This change makes that error go away, presumably because `reset()` without an argument closes the file.

Merge #12368: Hold mempool.cs for the duration of ATMP.
02fc886 Add braces to meet code style on line-after-the-one-changed. (Matt Corallo)
85aa839 Hold mempool.cs for the duration of ATMP. (Matt Corallo)

Pull request description:

  This resolves an issue where getrawmempool() can race mempool
  notification signals. Intuitively we use mempool.cs as a "read
  lock" on the mempool with cs_main being the write lock, so holding
  the read lock intermittently while doing write operations is
  somewhat strange.

  This also avoids the introduction of cs_main in getrawmempool()
  which reviewers objected to in the previous fix in #12273

Merge #12374: qt: Make sure splash screen is freed on AppInitMain fail
1e5d14b qt: Clarify some comments (Wladimir J. van der Laan)
f5a4c3d qt: Make sure splash screen is freed on AppInitMain fail (Wladimir J. van der Laan)

Pull request description:

  The `splashFinished` event was never sent if AppInitMain fails, causing the splash screen to stick around, causing problems later.

  This bug has existed for a while but is now trigging potential crashed because the splash screen subscribes to wallet events.

  Meant to fix #12372.
