Change getheaders messages so that we wait up to 2 minutes for a response to a
prior getheaders message before issuing a new one.
Also change the handling of the getheaders message sent in response to a block
INV, so that we no longer use the hashstop variable (including the hash stop
will just mean that if our peer's headers chain is longer, then we won't learn
it, so there's no benefit to using hashstop).
Also, now respond to a getheaders during IBD with an empty headers message
(rather than nothing) -- this better conforms to the intent of the new logic
that it's better to not ignore a peer's getheaders message, even if you have
nothing to give. This also avoids a lot of functional tests breaking.
p2p_segwit.py is modified to use this same strategy, as the test logic (of
expecting a getheaders after a block inv) would otherwise be broken.
Also moves the call to happen directly after validation of a headers message
(rather than mixed in with other state updates for the peer), and removes an
incorrect comment in favor of one that explains why headers sync must continue
from the last header a peer has sent.
Since:
- UpdateTransactionsFromBlock is only called by
MaybeUpdateMempoolForReorg, which calls it with the gArgs-determined
ancestor limits
- UpdateForDescendants is only called by UpdateTransactionsFromBlock
with the ancestor limits unchanged
We can remove the requirement to specify the ancestor limits for both
UpdateTransactionsFromBlock and UpdateForDescendants and just use the
values in the m_limits member.
Also move some removed comments to MemPoolLimits struct members.
The uint64_t cast in UpdateForDescendants is not new behavior,
see the diff in CChainState::MaybeUpdateMempoolForReorg for where they
were previously.
Better to be explicit when it comes to sizes to avoid unintentional
bugs. We use MB and KB all over the place.

- Store the mempool expiry (-mempoolexpiry) in CTxMemPool as a
std::chrono::seconds member.
- Remove the requirement to explicitly specify a mempool expiry for
LimitMempoolSize(...), just use the newly-introduced member.
- Remove all now-unnecessary instances of:
std::chrono::hours{gArgs.GetIntArg("-mempoolexpiry", DEFAULT_MEMPOOL_EXPIRY)}
The version of GetMinFee() with a custom size specification is and
should only be used by tests. Mark it as protected and use a derived
class exposing GetMinFee() as public in tests.
- Store the mempool size limit (-maxmempool) in CTxMemPool as a member.
- Remove the requirement to explicitly specify a mempool size limit for
CTxMemPool::GetMinFee(...) and LimitMempoolSize(...), just use the
stored mempool size limit where possible.
- Remove all now-unnecessary instances of:
gArgs.GetIntArg("-maxmempool", DEFAULT_MAX_MEMPOOL_SIZE_MB) * 1000000
The code change in CChainState::GetCoinsCacheSizeState() is correct
since the coinscache should not repurpose "extra" mempool memory
headroom for itself if the mempool doesn't even exist.
Reviewers: Note that CTxMemPool now requires a non-defaulted
CTxMemPool::Options for its constructor. Meaning that there's no need to
worry about a stray CTxMemPool constructor somewhere defaulting to
something incorrect. All instances of CTxMemPool construction are
addressed here in this commit.
We set options for CTxMemPool and construct it in many different ways. A
good example can be seen in how we determine CTxMemPool's check_ratio in
AppInitMain(...).
1. We first set the default based on chainparams's
DefaultConsistencyChecks()
2. Then, we apply the ArgsManager option on top of that default
3. Finally, we clamp the result of that between 0 and 1 Million
With this patch, most CTxMemPool construction are along the lines of:
MemPoolOptions mempool_opts{...default overrides...};
ApplyArgsManOptions(argsman, mempool_opts);
...hard overrides...
CTxMemPool pool{mempool_opts};
This "compositional" style of building options means that we can omit
unnecessary/irrelevant steps wherever we want but also maintain full
customizability.
For example:
- For users of libbitcoinkernel, where we eventually want to remove
ArgsManager, they simply won't call (or even know about)
ApplyArgsManOptions.
- See src/init.cpp to see how the check_ratio CTxMemPool option works
after this change.
A MemPoolOptionsForTest helper was also added and used by tests/fuzz
tests where a local CTxMemPool needed to be created.
The change in src/test/fuzz/tx_pool.cpp seemingly changes behaviour by
applying ArgsManager options on top of the CTxMemPool::Options defaults.
However, in future commits where we introduce flags like -maxmempool,
the call to ApplyArgsManOptions is actually what preserves the existing
behaviour. Previously, although it wasn't obvious, our CTxMemPool would
consult gArgs for flags like -maxmempool when it needed it, so it
already relied on ArgsManager information. This patchset just laid bare
the obfuscatory perils of globals.
[META] As this patchset progresses, we will move more and more
CTxMemPool-relevant options into MemPoolOptions and add their
ArgsMan-related logic to ApplyArgsManOptions.

fa1fe2e500 Remove LOCKTIME_MEDIAN_TIME_PAST constant (MarcoFalke)
Pull request description:
The constant is exposed in policy code, which doesn't make sense:
* Wallet and mempool need to assume the flag to be always active to function properly.
* Setting (or unsetting) the flag has no effect on policy code.
The constant is only used in `ContextualCheckBlock` (consensus code) to set a flag and then read the flag again. I think this can be better achieved by using a `bool`. If there is a need to use a flag in the future, it will be trivial to do so then.
(The previous use for the constant was removed in df562d698a)

Without ffile-prefix-map, the debug symbols will contain paths for the
guix store which will include the hashes of each package. However, the
hash for the same package will differ when on different architectures.
In order to be reproducible regardless of the architecture used to build
the package, map all guix store prefixes to something fixed, e.g. /usr.
We might be able to drop this in favour of using --with-nonshared-cflags
when we being using newer versions of glibc.

Wrap the syscall `getsockname()` in `Sock::GetSockName()` and change `GetBindAddress()` to take a `Sock` argument so that it can use the wrapper.

When filling a PSBT, we search the listed pubkeys in order to determine
whether the current DescriptorScriptPubKeyMan could sign the transaction
even if it is not watching the scripts. With Taproot, the taproot
pubkeys need to be searched as well.
The taproot spenddata stored in a sigdata is the combination of data
existing previously (e.g. in a PSBT) and the data stored in a
SigningProvider. In order to use the external data when signing, we need
to be using the sigdata's spenddata.
GetSpendData needs to be finalized in order to be used. To avoid future
bugs, assert `!m_output_key.IsNull()` as m_output_key is only set during
Finalize.
TaprootSpendData can be gotten from TaprootBuilder, however for PSBT, we
also need TaprootBuilders directly (for the outputs). So we store the
TaprootBuilder in the FlatSigningProvider and when the TaprootSpendData
is needed, we generate it on the fly using the stored builder.
