Moves stopatheight check into the ActivateBestChain loop so that the block height is actually checked and stopped at the appropriate time.
|
|
Since its free to do so, assert that Spends succeeded when we expect
them to.
|
|
|
|
CCoinsViewCache doesn't actually support cursor iteration returning the
current contents of the cache, so raise an error when the cursor method is
called instead of returning a cursor that iterates over stale data.
Also update the gettxoutsetinfo RPC which was relying on the old behavior to be
explicit about which view it is returning data about.

As the maximum amount of data that can be pulled into the cache due to
a block validation is much lower now (at most one CCoin entry per input
and per output), reduce the conservative estimate used to determine
flushing time.
|
|
This patch makes several related changes:
* Changes the CCoinsView virtual methods (GetCoins, HaveCoins, ...)
to be COutPoint/Coin-based rather than txid/CCoins-based.
* Changes the chainstate db to a new incompatible format that is also
COutPoint/Coin based.
* Implements reconstruction code for hash_serialized_2.
* Adapts the coins_tests unit tests (thanks to Russell Yanofsky).
A side effect of the new CCoinsView model is that we can no longer
use the (unreliable) test for transaction outputs in the UTXO set
to determine whether we already have a particular transaction.
|
|
|
|
This clarifies a bit more the ways in which the new script execution
cache could break consensus in the future if additional data from
the CCoins object were to be used as a part of script execution.
After this change, any such consensus breaks should be very visible
to reviewers, hopefully ensuring no such changes can be made.
|
|
|
|
This avoids a prevector copy in ApplyTxInUndo.
|
|
The earlier CTxInUndo class now holds the same information as the Coin
class. Instead of duplicating functionality, replace CTxInUndo with a
serialization adapter for Coin.

71f1903 Store disconnected block transactions outside mempool during reorg (Suhas Daftuar)
9decd64 [qa] Relax assumptions on mempool behavior during reorg (Suhas Daftuar)

Previously, transaction metadata (height, coinbase or not, and before
the previous commit also nVersion) was only stored for undo records
that correspond to the last output of a transaction being spent.
This only saves 2 bytes per undo record. Change this to storing this
information for every undo record, and stop complaining for having it
in non-last output spends. This means that undo dat written with
this patch won't be readable by older versions anymore.
|
|
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.
|
|
This is necessary later, when we drop the nVersion field from the undo
data. At that point deserializing and reserializing the data won't
roundtrip anymore, and thus that approach can't be used to verify
checksums anymore.
With this CHashVerifier approach, we can deserialize while hashing the
exact serialized form that was used. This is both more efficient and
more correct in that case.
|
|
The error() function unconditionally reports an error. It should only
be used for actually exception situations, and not for the type of
inconsistencies that ApplyTxInUndo/DisconnectBlock can graciously deal
with.
This also makes a subtle semantics change: in ApplyTxInUndo, when a
record with metadata is encountered (indicating it is the last spend
from a tx), don't wipe the CCoins record if it wasn't empty at that
point. This makes sure that UTXO operations never affect any other
UTXOs (including those from the same tx).

Rather than re-add disconnected block transactions back to the mempool
immediately, store them in a separate disconnectpool for later processing,
because we expect most such transactions to reappear in the chain that is
still to be connected (and thus we can avoid the work of reprocessing those
transactions through the mempool altogether).

DisconnectBlock currently has a complicated interface:
Situation Return value
pfClean != nullptr pfClean == nullptr
All good: true true
Failure: false false
Unclean rewind: true false
with *pfClean=false
Change this to return a tristate enum instead. As an added bonus,
remove the ValidationState& argument which was unused.
