This removes the attempt at magic (predicting future) component
called the fee-estimator.
The direct effect is that all transactions have as a mempool acceptance
the same minimum fee. Regardless of how full the mempool or blocks were.
This mempool-acceptance minimum fee is 0 sat/byte. (aka free)
Notice the node-wide free-tx accept-limiter is going to avoid us getting
overloaded.
This also includes a little blockchain of 114 blocks (the first 100 just
coinbase to reach coin-maturity) with transactions generated by the
txVulcano. So lots of outputs.
I adjusted the BlackBoxTest to load this data into any hub with ease.
This C++ library is a small framework which creates a full
http(s) server.
This is imported code from the qhttpengine open source project.
I modified some core components in order to make this framework
multi-threading and changed some APIs for cleanlyness. As such
it is not source compatible and getting it accepted upstream is
not realistic.
This adds all the header ints to chunked messages, solving the problem
of losing RequestId on roundtrips if the answer was too big.
Added a unit test for this "new" features.
This makes callbacks all use shared_from_this() in order to avoid
callbacks being done on deleted instances (thanks boost!).
Last, special case when the user doesn't connect but just sends messages
which caused a send of data, only to realize the connection wasn't open,
and then a connect.
This makes sure we immediately start a connect on queue of a message.
The "UAHF" one used to be "more equal", mostly just because it happened
to be the first.
This makes them all equally equal.
Specifically this removes the special casing and the enum for the 201708
HF (aka BCH fork-point).
We select the right branch now purely based on the historical check-
points.
When a blackbox test fails add the logs from the nodes
into the output of the log itself so they are all in one
place.
Especially handy for CI or docker usage where getting files
is a lot harder than getting standard-out.
The test assumed at least 2 cores, if you go below that (as the CI
dockers did) then we need to be aware of race-conditions when checking
on the status of the validation.
Remove txIndex option, its move to Flowee Indexer
Also remove the GUI option for setting the amount
of "script validator threads". :D
Remove DBCash command line option too, equally obsolete.
Also write some new accessor methods on the baseclass.
The longer term idea is to make the server itself only use the uint160
raw version for bitcoin addresses.
For now move the encodings (between that uint160 and human-readable) to
the utils library.
Instead of merging a small list into a bigger and bigger list,
write lots of small lists (20MB each or so) and then when we hit
the wanted final size, merge all of those into one.
In extreme cases we might end up going over the bounds of the internal
buffers, as such myConnection.send() may now throw.
I also cleaned up the ping design and made it a bit more strict.
Last I increased the amount of incoming data I can receive in one go,
this will make throughput higher.
as the number of applications grows it makes more sense to separate
the 'server' library from the actually reusable libraries.
To recap, the 'server' library is what we started with when importing
all the code from the hub. Slowly we are moving good code out that
is stand-alone and reusable.
The 'server' library has always been a catch-all and
ideally only the hub links it in (far future goal).
In line with this I move a list of files out of server
into the utils lib.
I choose 'utils' because all these are plain old data
objects that many crypto apps will find useful.
now in utils/primitives/
* CScript
* CPubKey
* CTransaction
* CBlock
* FastTransaction
* FastBlock
* CScript
streams.h is now in utils/streaming/
hash.h is now in utils/
The reason there are no standard library versions of lock-free
containers is because you want to always take full advantage of
the details in question.
In this case (read millions of times for each modification) it makes
no sense to use anything other than a standard container, but put in
a copy-on-write block. Simple and easy.
Replace the m_buckets unsorted map with a lock-free version
based on atomic pointers. (BucketMap)
remove the m_leafs and move those into the bucket struct.
Make the access to the jumptable transactional to avoid one big lock
over all datastructures.
On my threadripper 2990WX the entire 150GB BCH blockchain was
parsed and imported in under 3 hours.
