script.py is modified from the code in python-bitcoinlib, and provides tools
for manipulating and creating CScript objects.
bignum.py is a dependency for script.py
script_test.py is an example test that uses the script tools for running a test
that compares the behavior of two nodes, in a comptool- style test, for each of
the test cases in the bitcoin unit test script files, script_valid.json and
script_invalid.json. (This test is very slow to run, but is a proof of concept
for how we can write tests to compare consensus-critical behavior between
different versions of bitcoind.)
bipdersig-p2p.py is another example test in the comptool framework, which tests
deployment of BIP DERSIG for a single node. It uses the script.py tools for
manipulating signatures to be non-DER compliant.
comptool.py creates a tool for running a test suite on top of the mininode p2p
framework. It supports two types of tests: those for which we expect certain
behavior (acceptance or rejection of a block or transaction) and those for
which we are just comparing that the behavior of 2 or more nodes is the same.
blockstore.py defines BlockStore and TxStore, which provide db-backed maps
between block/tx hashes and the corresponding block or tx.
blocktools.py defines utility functions for creating and manipulating blocks
and transactions.
invalidblockrequest.py is an example test in the comptool framework, which
tests the behavior of a single node when sent two different types of invalid
blocks (a block with a duplicated transaction and a block with a bad coinbase
value).
mininode.py provides a framework for connecting to a bitcoin node over the p2p
network. NodeConn is the main object that manages connectivity to a node and
provides callbacks; the interface for those callbacks is defined by NodeConnCB.
Defined also are all data structures from bitcoin core that pass on the network
(CBlock, CTransaction, etc), along with de-/serialization functions.
maxblocksinflight.py is an example test using this framework that tests whether
a node is limiting the maximum number of in-flight block requests.
This also adds support to util.py for specifying the binary to use when
starting nodes (for tests that compare the behavior of different bitcoind
versions), and adds maxblocksinflight.py to the pull tester.

This commit adds several tests to the script_invalid.json data which
exercise some edge conditions that are not currently being tested.
These are mainly being added to cover several cases a branch coverage
analysis of btcd showed are not already being covered, but given more
tests of edge conditions are always a good thing, I'm contributing
them upstream.
The test which is intended to prove that the script engine is properly
rejecting non-minimally encoded PUSHDATA4 data is using the wrong
opcode and value. The test is using 0x4f, which is OP_1NEGATE instead
of the desired 0x4e, which is OP_PUSHDATA4. Further, the push of data
is intended to be 256 bytes, but the value the test is using is
0x00100000 (4096), instead of the desired 0x00010000 (256).
This commit fixes both issues.
This was found while examining the branch coverage in btcd against only
these tests to help find missing branch coverage.
This adds a -prune=N option to bitcoind, which if set to N>0 will enable block
file pruning. When pruning is enabled, block and undo files will be deleted to
try to keep total space used by those files to below the prune target (N, in
MB) specified by the user, subject to some constraints:
- The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP),
- N must be at least 550MB (chosen as a value for the target that could
reasonably be met, with some assumptions about block sizes, orphan rates,
etc; see comment in main.h),
- No blocks are pruned until chainActive is at least 100,000 blocks long (on
mainnet; defined separately for mainnet, testnet, and regtest in chainparams
as nPruneAfterHeight).
This unsets NODE_NETWORK if pruning is enabled.
Also included is an RPC test for pruning (pruning.py).
Thanks to @rdponticelli for earlier work on this feature; this is based in
part off that work.
Ever since #5957 there has been the problem that older RPC test cases
(as can be found plenty in open pulls) use setgenerate() on regtest,
assuming a different interpretation of the arguments. Directly
generating a number of blocks has been split off into a new method
`generate` - however using `setgenerate` with the previous arguments will
result in spawning an unreasonable number of threads, and well, simply
not work as expected without clear indication of the error.
Add an error to point the user at the right method.
It's reasonable that automatic coin selection will not pick a zero
value txout, but they're actually spendable; and you should know
if you have them. Listing also makes them available to tools like
dust-b-gone.
