Some regtest tests depend on manual fee injection to simulate certain
mempool conditions (e.g. lnwatcher_waits_until_fees_go_down). This is
done by manually injecting fee estimates into the `Network` object using
the `test_inject_fee_etas` cli command. However it can still happen that
the Network automatically updates its fee estimates from the connected
electrum server in the time between injecting the fee and the actual
tested logic making decisions based on the fee. This causes the test to
fail sometimes.
By setting the `test_disable_automatic_fee_eta_update` true the Network
will stop automatically updating the fee estimates and the test will
behave as expected.
Stops the running regtest if one test fails (using the --failfast
option) and makes the wallet data directories of alice, bob and carol
available for debugging. This seems helpful to fix issues only happening
on the CI.
peer initialization was never awaited in the `add_peer` method.
This awaits the initialization of the peer so that the caller
actually knows if connection succeeded or timed out.
Because `LNPeer.initialized` was awaited in
`LNPeer._query_gossip()` instead of the main loop the other tasks got
spawned concurrently and each task on its own has to wait for the
initialization. In `LNPeer._send_own_gossip()` this was missing, instead
there is a fixed 10 sec sleep. If the connection was not initialized but
the 10 sec are exceeded `_send_own_gossip()` tries to send gossip and
causes this exception as the `LNTransport` is not ready:

By awaiting the initialization directly in the `main_loop` it is more
clear that the task getting spawned subsequently depend on the transport
being available and separates the initialization more clearly these
other functions.
The string is not translated and might not be accessible for non-english
speakers, even though its relatively self-explanatory i think adding
this emoji makes it more accessible.
The ServerWidget was not working properly, when switching from "Manual
Mode" to "Auto Connect" the change wouldn't get saved as it depended on
having a correct server string entered (which isn't neccessary for Auto
Connect).
Also makes the widget behave more sane by cleaning the server input if
Auto Connect is enabled and switching to Manual Mode if the user
manually selects a server.
Update the ServerWidget every time it is shown (on initialization and
also when the user opens it again or switches between network dialog
tabs).
This will clean it up if the user has entered some invalid server and
closes it, otherwise this server would stay in the input field until the
application is restarted.
The list of servers in the ServerWidget allows the user to right click
and 'Use as server' on the servers in the list, however internally it
was handled differently than what the user would expect when clicking on
'Use as server'. E.g. if the user selects a server in autoconnect mode
it would still stay in autoconnect mode so the server could switch again
to another server any time? Now it will also change the mode to manual
(or stay in single server mode if that was selected before), making it
clear that this server will stay selected.
If the user clicks on "Follow this branch" the connect mode will get changed to
autoconnect as internally we connect to a random interface on this
branch.
Adds a 1024 (unpadded) byte budget to the PaddedRSTransport below which
messages are instantly flushed down the socket before the transport will
beginn waiting for the buffer to reach MIN_PACKET_SIZE (1024).
This allows to get the first couple of messages sent quickly when
starting the wallet to improve UX.
Prevents the client from accidentally connecting to a server on a
different network.
I noticed its possible to connect to mainnet servers on a signet
instance causing the recent peers to get populated with mainnet peers
rendering the wallet instance barely usable. Doing this check should
prevent this and similar issues.
..also export preimage in check_hold_invoice return value if available.
I intentionally did not return the preimage in the returned dict of
wallet.export_requests as this seems risky to do considering some users
of the cli might forward the response to a payer and the payserver
exposes it too.
Closes https://github.com/spesmilo/electrum/issues/10176
Enforce that the information used to create a bolt11 invoice using
`get_bolt11_invoice()` is similar to the related instance of PaymentInfo
by requiring a PaymentInfo as argument for `get_bolt11_invoice()`.
This way the invoice cannot differ from the created PaymentInfo.
This allows to use the information in PaymentInfo for validation of
incoming htlcs more reliably.
To cover all required information for the creation of a b11 invoice the
PaymentInfo class has to be extended with a expiry and
min_final_cltv_expiry. This requires a db upgrade.
Renames RecvMPPResolution.ACCEPTED to .COMPLETE as .ACCEPTED is somewhat
misleading. Accepted could imply that the preimage for this set has been
revealed or that the set has been settled, however it only means that we
have received the full set (it is complete), but the set still can be
failed (e.g. through cltv timeout) and has not been claimed yet.
makes hmac comparisons and onion error decoding more constant time
according to bolt 4. However things might still not be perfectly
constant time, however this seems out of scope for timing over network.
