The LevelDB docs seem to indicate that an iterator will not take
snapshots (even providing instructions on how to do so yourself).
In several of the places we use them, we assume snapshots to have
been taken.
In order to make sure LevelDB doesn't change out from under us
(and to prevent the next person who reads the docs from having the
same fright I did), verify that snapshots are taken in our tests.
This eases the during-type validation to allow Bech32 chars.
Once the focus has been lost, the address will be properly verified through IsValidDestinationString
In the SignatureHash function, the input index must refer to a valid
index. This is not enforced equally in the segwit/non-segwit branches
and should be an assertion rather than returning a error hash.
This adds the infrastructure `BaseRequestHandler` class that takes care
of converting bitcoin-cli arguments into a JSON-RPC request object, and
converting the reply into a JSON object that can be shown as result.
This is subsequently used to handle the `-getinfo` option, which sends
a JSON-RPC batch request to the RPC server with
`["getnetworkinfo", "getblockchaininfo", "getwalletinfo"]`,
and after reply combines the result into what looks like a `getinfo`
result.
There have been some requests for a client-side `getinfo` and this
is my PoC of how to do it. If this is considered a good idea
some of the logic could be moved up to rpcclient.cpp and
used in the GUI console as well.

Changes the errors field to warnings. To maintain compatibility,
the errors field is deprecated and enabled by starting bitcoind with
-deprecatedrpc=getmininginfo
This should make it easier to debug issues where the CheckBlock at
the top of ProcessNewBlock fails (which does not print, in contrast
to AcceptBlock, which always prints).
Deprecate estimatefee in v0.16, for final removal in v0.17.
This commit introduces a phased removal of RPC methods. RPC method is
disabled by default in version x, but can be enabled by using the
`-deprecatedrpc=<method>` argument. RPC method is removed entirely in
version (x+1).
Prevent arbitrary files from being overwritten. There have been reports
that users have overwritten wallet files this way. It may also avoid
other security issues.
Fixes#9934. Adds mention to release notes and adds a test.
Writes the GUI settings to `guisettings.bak` in the data directory
before wiping them. This can be used to retroactively troubleshoot
issues (e.g. #11262) where `-resetguisettings` solves the problem.
In the case of CKey's destructor, it seems to have been an oversight in
f4d1fc259 not to delete it. At this point, it results in the move
constructors/assignment operators for CKey being deleted, which may have
a performance impact.
by individual transactions to 2 places (but call only once in each):
- ConnectBlock ( before calculated fees per txs twice )
- AcceptToMemoryPoolWorker ( before called CheckTxInputs 4 times and calculated
fees per tx one extra time )
Also call tx.GetValueOut() only once per call of CheckTxInputs (instead of 2)
This was added in order to help OpenNetworkConnection avoid creating a
connection that it would end up aborting. It was necessary because resolving
was done as part of the connection process.
Now that resolving is separated from connecting, this case is detected before
the connection is attempted.
ConnectSocketByName handled resolves as necessary, obscuring the connection
process. With them separated, each can be handled asynchronously.
Also, since proxies must be considered now anyway, go ahead and eliminate the
ConnectSocket wrapper and use ConnectSocketDirectly... directly.
std::unordered_map::erase( const_iterator pos ) returns an iterator to the element following the removed one. Use that to optimize (probably minor-performance-wise, and definitely code-structure-wise) the implementation of CCoinsViewCache::BatchWrite().
Use C++11's better capability of expressing an interface of a non-copyable class by publicly deleting its copy ctor and assignment operator instead of just declaring them private.
- Move comment about transaction/block weight calculation so it applies not only to the GetBlockWeight function but also to GetTransactionWeight
- Fix comment in validation.cpp referencing future deployment of BIP113. It has already been deployed.
- The doc comment for BLOCK_DOWNLOAD_WINDOW wasn't updated since pruning was introduced, so it still refers to pruning as something that might happen in the future. A larger BLOCK_DOWNLOAD_WINDOW window would now, indeed, make pruning harder.
Make the non-const overload of CBlockIndex::GetAncestor() reuse the const overload implementation instead of the other way around. This way, the constness of the const overload implementation is guaranteed. The other way around, it was possible to implement the non-const overload in a way which mutates the object, and since that implementation would be called even for const objects (due to the reuse), we would get undefined behavior.
