* Rename synchronous_get to synchronous_send
This makes it more inline with the method 'send' of which
synchronous_send is the, well, synchronous version.
* Move protocol strings from scripts to network
This is again a small step in the right direction. The network module is
going to accumulate more and more of these simple methods. Once
everything is moved into that module, that module is going to be split.
Note that I've left the scripts which use scripts/util.py alone. I
suspect the same functionality can be reached when using just
lib/network.py and that scripts/util.py is obsolete.
* Remove protocol string from verifier and websocket
Websocket still has some references, that'll take more work to remove. Once the
network module has been split this should be easy.
I took the liberty to rename a variable to better show what it is.
* Remove protocol strings from remainder
The naming scheme I'm following for the newly introduced methods in the network
module is: 'blockchain.<subject>.<action>' -> def <action>_(for|to)_<subject>
* Move explicit protocol calls closer to each other
This makes it easier to keep track of the methods which are due to be
extracted.
* Remove `send` when using `get_transaction`
This is the final step to formalize (the informal) interface of the network
module.
A chance of note is changed interface for async/sync calls. It is no longer
required to use the `synchronous_send` call. Merely NOT passing a callback
makes the call synchronous. I feel this makes the API more intuitive to work
with and easier to replace with a different network module.
* Remove send from get_merkle_for_transaction
The pattern which emerged for calling the lambda yielded an slight refactor.
I'm not happy with the name for the `__invoke` method.
* Remove explict send from websockets
* Remove explicit send from scripts
* Remove explicit send from wallet
* Remove explicit sync_send from commands, scripts
* Remove optional timeout parameter
This parameter doesn't seem to be used a lot and removing it makes the
remaining calls easier. Potentionally a contentious choice!
* Rename `broadcast` to `broadcast_transaction`
Doing so makes the method name consistent with the other ElectrumX protocol
method names.
* Remove synchronous_send
Now every method is intuitive in what it does, no special handling required.
The `broadcast_transaction` method is weird. I've opted not to change the
return type b/c I found it hard to know what the exact consequences are. But
ideally this method should just works as all the other ElectrumX related
messages. On the other hand this shows nicely how you _can_ do something
differnt quite easy.
* Rename the awkwardly name `__invoke` method
The new name reflects what it does.
* Process the result of linter feedback
I've used flake8-diff (and ignored a couple of line length warnings).
* Rename tx_response to on_tx_response
This fell through the cracks when this branch was rebased.
* subscript_to_scripthash should be get_balance
An oversight while refactoring.
* Add missing return statement
Without this statement the transaction would have been broadcasted twice.
* Pass list of tuples to send not single tuple
* Add @staticmethod decorator
* Fix argument to be an array
wallet.synchronizer gets assigned a newly constructed Synchronizer instance.
Synchronizer in tx_response refers to the value of wallet.synchronizer.
If the wallet has a missing txn, there could be a race condition that synchronizer asks for a txn and we get the callback from the network WHILE the constructor is still running, in which case wallet.synchronizer would still be None and we would consider the callback "orphan", and the wallet would get "stuck" synchronizing.
- separation between Wallet and key management (Keystore)
- simplification of wallet classes
- remove support for multiple accounts in the same wallet
- add support for OP_RETURN to Trezor plugin
- split multi-accounts wallets for backward compatibility
As per BIP44, 20 addresses are checked for transactions, not just the
first one.
Show the last account only if used or named.
If all accounts are used, prompt for password to create new one.
Fixes#1128
This should speed up synchronization / restoration of large wallets.
Wallets are written only when they switch to up_to_date state, or
when stop_threads() is called when closing the daemon, or when
a command line command finishes.
Proper fix for #1525.
Using python's GC module, I've verified that the daemon, when running,
now releases all verifiers, synchronizers and wallets - all the resources
we care about releasing.
The synchronizer's work is done from the network proxy's main loop.
A minor problem with the old synchronizer was that it considered itself
out of date if the network was out of date. This was too generic: the
network can have pending requests unrelated to the synchronizer. This
resulted in the synchronizer often unnecessarily flipping the wallet
between up-to-date and not-up-to-date, and causing unnecessary calls
to wallet.save_transactions(). This was observable when opening the
network dialog box: frequently just opening it would cause a wallet
status change and transaction flush, simply because the network dialog
sends a get_parameters() request. This rework of the synchronizer does
not have that issue.
