Merge #11530: Add share/rpcuser to dist. source code archive
fa81534 Add share/rpcuser to dist. source code archive (MarcoFalke)

Pull request description:

  As the legacy rpcuser and rpcpassword are deprected since 0.12.0, we should actually include the script to generate the new auth pair in the distributed source code archive.

  Ref: #6753

  (Tagging for backport, since it is a trivial bugfix)

659b2061c4 Make listsinceblock refuse unknown block hash
Change suggested by Cory Fields <cory-nospam-@coryfields.com> who noticed
listsinceblock would ignore invalid block hashes causing it to return a
completely unfiltered list of transactions.

Merge #11538: qa: Fix race condition failures in replace-by-fee.py, sendheaders.py
6d51eaefe qa: Fix race condition in sendheaders.py (Suhas Daftuar)
c96b2e4f0 qa: Fix replace-by-fee race condition failures (Suhas Daftuar)

Pull request description:

  I think #11407 broke replace-by-fee by introducing a race condition.  I was observing frequent failures of replace-by-fee locally, always with a mempool sync failure (the sync call was added in #11407).

  It appeared to me like there were two causes: sometimes the node would be in IBD and not request the transaction that was relayed; other times the blocks generated in make_utxo wouldn't have relayed quickly enough for the spend of the transaction to be accepted.  I believe I've fixed both potential errors.

  ping @instagibbs

  Edit: I found a race condition in the sendheaders.py test, where if the verack from the python node wasn't processed before the first block in the test was generated, then no block announcement would go out to that peer, breaking the test.  Fixed by adding a sync_with_ping after waiting for verack.

08fd822 qa: add test for minchainwork use in acceptblock (Suhas Daftuar)
ce8cd7a Don't process unrequested, low-work blocks (Suhas Daftuar)

Pull request description:

  A peer could try to waste our resources by sending us unrequested blocks with
  low work (eg to fill up our disk).  Since e265200 we no longer request blocks until we
  know we're on a chain with more than nMinimumChainWork (our anti-DoS
  threshold), but we would still process unrequested blocks that had more work
  than our tip (which generally has low-work during IBD), even though we may not
  yet have found a headers chain with sufficient work.

  Fix this and add a test.

Merge #11062: [mempool] Mark mempool import fails that were found in mempool as 'already there'
258d33b41 [mempool] Mark unaccepted txs present in mempool as 'already there'. (Karl-Johan Alm)

Pull request description:

  I was investigating the reasons for failed imports in mempool and noticed that `LoadMempool()` and `pwallet->postInitProcess()` (for all wallets) are executed concurrently. The wallet will end up importing transactions that `LoadMempool()` later tries to import; the latter will fail due to the tx already being in the mempool.

  This PR changes the log message, adding an additional "already there" entry. For transactions not accepted into mempool, a check if they are in the mempool is done first, and if found, they are counted as 'already there', otherwise counted as 'failed'.

  Also slight rewording for consistency (successes, failed, expired, ... -> succeeded, failed, expired).

Merge #11483: Fix importmulti bug when importing an already imported key
a44a21517 Fix importmulti bug when importing an already imported key (Pedro Branco)

Pull request description:

  This PR fixes a bug in `importmulti` RPC call where it returns an invalid response when importing an already imported key.

  Before:
  ```sh
  ❯ bitcoin-cli -regtest importmulti '[{ "keys": ["cNcMUunXhVK1dXJ5riixtpYSxPXZnUAMGS4vpzwChdKmYY3Rz99v"], "scriptPubKey": { "address": "n4YZAf4WE2XF3t4BfeYS2nHAhb8CVx91BR" }, "timestamp": 1507655239 }]'
  [{ "success": true }]

  ❯ bitcoin-cli -regtest importmulti '[{ "keys": ["cNcMUunXhVK1dXJ5riixtpYSxPXZnUAMGS4vpzwChdKmYY3Rz99v"], "scriptPubKey": { "address": "n4YZAf4WE2XF3t4BfeYS2nHAhb8CVx91BR" }, "timestamp": 1507655239 }]' '{ "rescan": false }'
  [ false ]

  ❯ bitcoin-cli -regtest importmulti '[{ "keys": ["cNcMUunXhVK1dXJ5riixtpYSxPXZnUAMGS4vpzwChdKmYY3Rz99v"], "scriptPubKey": { "address": "n4YZAf4WE2XF3t4BfeYS2nHAhb8CVx91BR" }, "timestamp": 1507655239 }]' '{ "rescan": true }'
  error code: -1
  error message:
  JSON value is not a boolean as expected
  ```

  After this fix:
  ```sh
  ❯ bitcoin-cli -rpcuser=u -rpcpassword=p -regtest importmulti '[{ "keys": ["cNcMUunXhVK1dXJ5riixtpYSxPXZnUAMGS4vpzwChdKmYY3Rz99v"], "scriptPubKey": { "address": "n4YZAf4WE2XF3t4BfeYS2nHAhb8CVx91BR" }, "timestamp": 1507655139 }]'
  [{ "success": true }]

  ❯ bitcoin-cli -rpcuser=u -rpcpassword=p -regtest importmulti '[{ "keys": ["cNcMUunXhVK1dXJ5riixtpYSxPXZnUAMGS4vpzwChdKmYY3Rz99v"], "scriptPubKey": { "address": "n4YZAf4WE2XF3t4BfeYS2nHAhb8CVx91BR" }, "timestamp": 1507655139 }]'
  [{ "success": false, "error": { "code": -4, "message": "The wallet already contains the private key for this address or script" } }]
  ```

Merge #11513: [trivial] [tests] A few Python3 tidy ups
f89308532 [tests] Don't subclass from object for Python 3 (John Newbery)
8f9e3627e [tests] authproxy.py: tidy up __init__() (John Newbery)
323d8f61e [tests] fix flake8 warnings in authproxy.py (John Newbery)
fc0176d01 [tests] use python3 for authproxy.py (John Newbery)

Pull request description:

  A few trivial tidyups in the test_framework:

  - the test_framework can only be run in Python3, so remove the py2/3 compatibility workarounds in authproxy.py
  - while there, do some general tidying up of the module - fix flake8 warnings, make initialization code more compact
  - All classes in Python3 are new-style. No need to explicitly inherit from `object`.
