Buyer was not verifying if the donation address is either the default
DAO param address or the recent one changed by DAO voting. We do not
support past DAO param addresses to avoid that past addresses receive
funds.
Testing showed that the new mechanic for checking a local BTC node's
configuration is unstable. This commit reverts to just checking if the
relevant port is open. The recent refactoring and centralization of
logic is still in place.
Bisq frequently (once per minute) queries our price nodes for up-to-date
fee information. It does so by HTTP GET request. However, it provided
a UID via the "User-Agent" HTTP header field. This UID has been a random
number which changed everytime Bisq gets started up.
This UID has never been used. Thus, remove it.
This was originally added with the intention that the local Bitcoin node
port could be customized, but in fact it never could be, because Guice
configuration always hard-wired the value to the default port for the
CurrentBaseNetwork's Parameters (eg. 8333 for BTC_MAINNET).
This change removes the constant, removes any Guice wiring and injection
and localizes the hard-coded assignment to the LocalBitcoinNode
constructor to simplify and make things explicit.
If it is desired to allow users to specify a custom port for their local
Bitcoin node, a proper option shoud be added to Config. In the meantime,
users may work around this by using `--btcNodes=localhost:4242` where
4242 is the custom port. Note however, that the pruning and bloom filter
checks will not occur in this case as the provided node address will not
being treated as a LocalBitcoinNode.
Introduces LocalBitcoinNode::willUse and ::willIgnore to move logic that
was previously littered throughout the codebase into one place. Also,
changes the usages of LocalBitcoinNode to be more precise, specifying
which of these questions are being asked:
- "is there a local BTC node" (isDetected);
- "is it well configured" (isWellConfigured and isUsable);
- "will we ignore a local BTC node even if we found a usable one"
(willIgnore);
- "is there a usable local BTC node and will we use it" (willUse).
These changes make related logic much easier to maintain and to read.
It's quite amazing how obvious this was, yet I missed it for such a long
time. Simplifies usage of LocalBitcoinNode and its internals even more
so. Fixes#4005. The way we structured LocalBitcoinNode was as if the
detection checks were expensive, but they're not. Previously, in some
cases we would notice that a local BTC node wouldn't be used even if it
was detected, so we would skip these checks. This optimization now
doesn't happen. It might be reimplemented in a coming change where more
local BTC node logic is moved into LocalBitcoinNode, but, even if it's
not, this check is fairly cheap. A notable exception is if the local BTC
node is not responding, which would cause us to wait for a timeout, but
if that is the case the mentioned optimization wouldn't help (most of
the time).
The workings of LocalBitcoinNode significantly changed, especially how
detection works. Before, we were only checking if a port was open, but
now we're actually performing a Bitcoin protocol handshake, which is
difficult to stub. For these reasons the old tests are irrelevant and
replacement tests were not written.
