This removes obviously no longer correct macos code
This adds a workaround for Android not detecting the libs sometimes.
Works because we use our docker where we know the locations.
The onDisconnected callback is moved to later in the process after the
internal state has been updated so calling 'isConnected()' is what you'd
expect.
This reverts commit e28b5e1823.
The port number is again passed through the dns lookup, which is
weird as fuck but needed to get the actual resulting iterator still
have the port numebr we wanted to connect to.
The cmake boost integration has changed, which means we need to
test how to do this over a large number of setups to do
it "correctly" and that's going to be a task for later.
For now, lets avoid the message and make clear we want to keep
the old behavior.
The checkpoints were formerly copied from the full node, so based
on possible fork-events.
That seems less useful nowadays and since we want to be able to
allow starting a blockchain instance from any checkpoint it makes
sense to spread them out more evenly.
Based on the concept that the BCH chain generates around 50K blocks
a year, we simply use that interval.
This removes various very old ones meaning that the total count is
roughly equal.
This improves the docs, adds a getter and last it makes the
blockHeightAtTime() more secure by not returning a value below the
checkpoint. As this would throw if used directly in the block() method.
This adds endsWith() and an extra startsWith() overload.
We also added tests for the case when either the argument or the object
are empty and specify the behavior. I copied the behavior of QString.
See unit tests that specify the behavior with empties.
This public method allows an application to replace the static-
header files in a life-situation. Without needing to restart the app.
The idea is that a static chain starts at a checkpoint, and we extend
it into the past to start at an earlier checkpoint. This suddenly
makes available a larger amount of history without changing anything
of the data that was already there.
The blockchain object holds all block-headers, the backing store for
this class is now being exposed more to allow understanding what we have
or not have available. And also what the source of that info is.
As the "normal" machine that runs this kind of software gets more
memory, it is Ok to increase the numbers in order to aim to keep more
data cached in memory between check-points, and have less check-points.
This mostly helps speeding up initial block download, it also helps keeping
the utxo datadir small and non-fragmented. All good for speed.
