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.
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 some files back to the server "library".
Merge the 'console' lib with server, as it doesn't really make sense with
just one file and nobody exclusively linking to it.
The server "libary" is not really a library, its the place we put all
the files shared by hub-qt hub-cli and hub.
We no longer depend on these files from other places (mostly due to
moving to the new logging framework) and as such we can move the files
back.
Move some globals and all stuff pulling in crypto to the
server/serverutil.cpp file
Remove dead code.
Move several items that were used in only one place to the respective
files using them.
Move the class WaitUntilFinishedHelper into its own file.
Made sure no header includes utils.h
remove a handfull of files including utils.h for nothing.
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.
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.
Should a user point to a config file with the option `-conf` then
we will read the testnet/regtest options from that file.
This does not change the old behavior. To be clear;
Should a user pass -regtest on the commandline (and not -conf) then
we will only read the config file from the regtest subdir
(~/.config/flowee/regtest).
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.
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/
During the BCH fork-off time we allowed the client to be started
as either BCH or BTC and as such there are several code-paths
that behave different based on this user setting.
We remove those as we no longer allow starting as BTC client.
This also removes the check for the min-block-size (rollback protection)
as this is accomplished by the checkpoints on the BCH chain.
