update_checkpoints() makes a few DNS requests and can take up to 20-30 seconds to complete (3-6 seconds on average). It is currently called from core::handle_incoming_block() which holds m_incoming_tx_lock, so it blocks all incoming transactions and blocks processing while update_checkpoints() is running. This PR moves it to until after a new block has been processed and relayed, to avoid full monerod locking.
Being offline is not a good enough heuristic, so we keep track
of whether the wallet ever refreshed from a daemon, which is a
lot better, and probably the best we can do without manual user
designation (which would break existing cold wallet setups till
the user designates those wallets)
- spend secret key is no longer the sum of multisig key shares;
no need to check that is the case upon restore.
- restoring a multisig wallet from multisig info means that the
wallet must have already completed all setup rounds. Upon restore,
set the number of rounds completed accordingly.
There are vulnerabilities in multisig protocol if the parties do not
trust each other, and while there is a patch for it, it has not been
throroughly reviewed yet, so it is felt safer to disable multisig by
default for now.
If all parties in a multisig setup trust each other, then it is safe
to enable multisig.
Implements view tags as proposed by @UkoeHB in MRL issue
https://github.com/monero-project/research-lab/issues/73
At tx construction, the sender adds a 1-byte view tag to each
output. The view tag is derived from the sender-receiver
shared secret. When scanning for outputs, the receiver can
check the view tag for a match, in order to reduce scanning
time. When the view tag does not match, the wallet avoids the
more expensive EC operations when deriving the output public
key using the shared secret.
The integrated address functional test fails in the workflows due
to an assertion for missing payment id that is no longer needed.
Remove the assertion and update the assertion count.
Fixes 7dcfccb: ("wallet_rpc_server: fix make_integrated_address with no payment id")
It avoids dividing by 8 when deserializing a tx, which is a slow
operation, and multiplies by 8 when verifying and extracing the
amount, which is much faster as well as less frequent
* Remove `match_string()`, `match_number()`, and `match_word()`
* Remove `match_word_with_extrasymb()` and `match_word_til_equal_mark()`
* Adapt unit test for `match_number()` to `match_number2()`
* Adapt unit test for `match_string()` to `match_string2()`
Note: the unit tests were testing for the old version of the functions, and
the interfaces for these functions changed slightly, so I had to also edit
the tests.
As of writing, this PR has no merge conflicts with #8211
Additional changes during review:
* Explicitly set up is_[float/signed]_val to be changed before each call
* Structify the tests and fix uninitialized variables
