This commit marks the start/stop functions in util.py as private module
functions. A future PR will remove these entirely and move the
functionality directly into the BitcoinTestFramework class, but setting them as
private in this PR will prevent anyone from accidentally calling them
before that future PR is merged.
This makes the following changes:
* In undo data and the chainstate database, the transaction nVersion
field is removed from the data structures, always written as 0, and
ignored when reading.
* The definition of hash_serialized in gettxoutsetinfo is changed to no
longer incude the nVersion field. It is renamed to hash_serialized_2
to avoid confusion. The new definition also includes transaction
height and coinbase information, as this information was missing
before.
This depends on having a CHashVerifier-based undo data checksum
verifier.
Apart from changing the definition of serialized_hash, downgrading
after using this patch is supported, as no release ever used the value
of nVersion field in UTXO entries.
Change the logic of estimateSmartFee to check a 60% threshold at half the target, a 85% threshold at the target and a 95% threshold at double the target. Always check the shortest time horizon possible and ensure that estimates are monotonically decreasing. Add a conservative mode, which makes sure that the 95% threshold is also met at longer time horizons as well.
Checks memory before and after a transaction that requires a private key.
Each time, 32 bytes of memory for a private key should be used.
Tested in wallet.py instead of its own file to save testing time.
This test was passing because we never fetch blocks if we only receive
an inv and not the header (after 037159cebf),
and this test wasn't delivering the header.
Policy limits (such as chain limits and mempool total size) could reasonably
be enforced more aggressively during a reorg, so use resendwallettransactions
to repopulate the mempool to avoid mined blocks being too small, and increase
the chain limits from the default for this test.
This is in preparation for a change in mempool behavior during a reorg.
* Split run_test into 4 separate tests
* Add 2 tests, getconnectioncount and getnettotals
* getnettotals - Strategy of test is to get the network stats before and after a ping. The difference in bytes sent/received is the bytes needed for a ping/pong.
This commit uses the new skip test funcationality added in
232b6665bc to skip the zmq tests if the
python zmq module is not available or if bitcoind has been built without
zmq support.
This removes the zmq-specific logic from test_runner.py. In general it's
better if test_runner.py has no knowledge of special cases for
individual tests and is a general purpose test runner.
