After discussion in #7164 I think this is better.
Max tip age was introduced in #5987 to make it possible to run
testnet-in-a-box. But associating this behavior with the testnet chain
is wrong conceptually, as it is not needed in normal usage.
Should aim to make testnet test the software as-is.
Replace it with a (debug) option `-maxtipage`, which can be
specified only in the specific case.

This switches the Merkle tree logic for blocks to one that runs in constant (small) space.
The old code is moved to tests, and a new test is added that for various combinations of
block sizes, transaction positions to compute a branch for, and mutations:
* Verifies that the old code and new code agree for the Merkle root.
* Verifies that the old code and new code agree for the Merkle branch.
* Verifies that the computed Merkle branch is valid.
* Verifies that mutations don't change the Merkle root.
* Verifies that mutations are correctly detected.

e761d7a Bugfix: Allow mining on top of old tip blocks for testnet (fixes testnet-in-a-box use case) (Luke Dashjr)

testnet-in-a-box use case)

Assume that when a wallet transaction has a valid block hash and transaction position
in it, the transaction is actually there. We're already trusting wallet data in a
much more fundamental way anyway.
To prevent backward compatibility issues, a new record is used for storing the
block locator in the wallet. Old wallets will see a wallet file synchronized up
to the genesis block, and rescan automatically.

17221bf chainparams: don't use std namespace (Cory Fields)
f0deec5 chainparams: move CCheckpointData into chainparams.h (Cory Fields)
|
|
Clean up the code in chainparams a bit more after the recent
refactorings. In particular, make sure the structure of the "RegTest"
params matches the structure of the other classes. This makes the code
clearer to read.
Also remove redundant values of the genesis block in always-specified
optional arguments and mark variable/argument as "const".

This unties CChainParams from its dependency on checkpoints. Instead, now it
only depends on the raw checkpoint data.

85ee55b rpc: Remove chain-specific RequireRPCPassword (Wladimir J. van der Laan)
|
|
...instead of CMainParams and CTestNetParams respectively
Do the same for CBaseChainParams.
The inheritance was only reducing readibility in this case

I've never liked the chain-specific exception to having to set a
password. It gives issues with #6388 which makes it valid to
set no password in every case (as it enables random cookie authentication).
This pull removes the flag, so that all chains are regarded the same.
It also removes the username==password test, which doesn't provide any
substantial extra security.
|
|
No longer relevant after #5957. This hack existed because of another
hack where the numthreads parameter, on regtest, doubled as how many
blocks to generate.
|
|
If/when CTransaction::CURRENT_VERSION is incremented, this will break CChainParams and the miner tests. This fix sets the transaction version explicitly where we depend on the hash value (genesis block, proof of work checks).

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.

Requiring arith_uint256 at such a base level is not good for modularity.
|
|
This adds a -checkblockindex (defaulting to true for regtest), which occasionally
does a full consistency check for mapBlockIndex, setBlockIndexCandidates, chainActive, and
mapBlocksUnlinked.
|
|
|
|
Not used, and REGTEST already allows creating blocks at
the lowerst possible difficulty.
|
|
UNITTEST parameter are not used by any current tests, and the model
(modifyable parameters) is inconvenient when unit-testing. As
they are stored in a global structure eevery test
would have to (re)set up its own parameters.
For consistency it is also better to test with MAIN parameters.

eb0d34b Remove unused chainparam networkID (jtimon)

Also add conversion from/to uint256 where needed.
|
|
If uint256() constructor takes a string, uint256(0) will become
dangerous when uint256 does not take integers anymore (it will go
through std::string(const char*) making a NULL string, and the explicit
keyword is no help).
|
|
Replace x=0 with .SetNull(),
x==0 with IsNull(), x!=0 with !IsNull().
Replace uses of uint256(0) with uint256().
|
|
A few boost::asio were left around because they're very wordy otherwise.

|
I'm not comfortable with retaining this entry.
