This makes it possible for the most recent file to not be the default
filesize but much smaller. This fixes us to writing outside of the
allocated membuffer and causing a kernel signal.
Additionally we start a new file for writes in that case.
This case is seen in the unit tests where we have a perfect-fitting file
in git which we then try to write to when adding a new block.
As such this is tested in the upcoming unit test.
This new flag to the getBlock API call allows us to select
a transaction based on the usage of a certain script opcode.
This uses the new metadata index.
For the txid/fee index we do a bit more than we can do for shallow block
validation.
Now we don't actually fully validate all transactions when this index is
enabled, we just fetch the fees.
The code that connects blocks together uses the block-hash (blockId) for
that, which we always just created on the fly.
Instead store the blockId on the state and in that way make adding
headers not entirely in-sequence be 10 times as fast.
Additionally, we wait with actual validation after a reindex until the
files are all found because otherwise we can't save the meta blocks.
This adds an option to the GetTransaction Flowee API to return the fees
for a whole transaction.
Support for this is added in the Blockchain (searcher) and the
RestService components.
Notice that no fees will be returned if the BlockMetaData was not
created properly.
this allows the user to ensure the metadata blocks fetch the previous
transaction in order to calculate the transaction-fee.
Normally this is skipped for transactions we don't need to do the script
validation for (old blocks).
[code-quality]
We got a warning about a dereference of a nullptr. But that implied we
have an impossible combination of member variables.
So, lets assert on that being impossible so;
a) we get a fail-fast if this ever happens.
b) the static code checker will stop warning us.
Notice that asserts are compiled out of release executables. So this is
effectively a no-op for releases.
This introduces several options for public node operators to limit their
nodes usage by 3rd parties, this is aimed at usage of resource-hungry
areas.
We allow limiting the amount of connections any single IP can keep open
with us.
We limit the amount of reconnects we allow in a short number of seconds.
We allow limiting the number of addresses (or scriptHashes) a peer can
register for the node to scan.
The last one is for both the addressMonitorService as well as for the
getBlock filters.
For node operators these items become available using command line
options or config-file options. By default these limits are unlimited as
we assume default usage to be private.
as the expected behavior of 'get*' is a const method, it is harmful to
name a method such when it actually alters the state of the method such
that subsequent calls will produce a different result.
This does remove the feature that mining can use the internal wallet as
a source of coinbase addresses, but since Flowee doesn't actually ship a
wallet, that was just not a good reason to keep an unused class in the
libs.
The CAmount name is not helpful as its just an int64_t and not a
class, like the name implies. There were a handful of places where
it was passed in as const-ref, as a good example of this actually
creating sub-par code.
Move the MutableTransactionSignatureChecker class out of the header and
thereby remove the need to include transaction.h in the header.
This checker was never used in any app, just in the unit tests.
This also fixes includes around.
The API throws when the directories already exist, which is quite
unexpected.
This now changes the code to silently ignore these issues in the
knowledge that the immediately following opening of files will
fail with a nice error message.
This adds a unit test to see if the combination of invalidateBlock and
reconsiderBlock do what we expect to do.
The main issue was that we store an invalidated block in the UTXO and we
forgot to re-validate that on reconsider.
Additionally I avoid writing a lot of unchanged data to the block-index.
