decorators (instead of overloading JsonDB._convert_dict and
_convert_value)
- stored_in for elements of a StoreDict
- stored_as for singletons
- extra register methods are defined for key conversions
This commit was adapted from the jsonpatch branch
The standard json module has an optimized C encoder, but that doesn't
currently support indentation. So if you request indentation, it falls
back on the slower Python encoder.
Readability doesn't matter for encrypted wallets, so this disables
indentation when the wallet is encrypted.

For a large encrypted wallet, compare:
before change:
JsonDB.dump 1.3153 sec
zlib.compress 1.281 sec
ECPubkey.encrypt_message 0.1744 sec
after change:
JsonDB.dump 0.5059 sec
zlib.compress 1.3120 sec
ECPubkey.encrypt_message 0.1630 sec

The keystore logic would need to be significantly changed to nicely
interoperate with StoredDict/json_db logic.
(just see KeyStore.__init__() and KeyStore.dump())
For now we exempt the keystore from the recursive StoredDict conversion, as
it is a smaller change that is also easier to review for correctness.
fixes#6066fixes#6401
also reverts 2d3c2eeea9 (which was an even hackier workaround for #6066)
this is a regression from #5721
Removed the `TxInput.is_coinbase` method as I think it is a confusing API,
instead we now have `TxInput.is_coinbase_input` and `TxInput.is_coinbase_output`.
related #5872
Note that there is a slight distinction between
`not tx.is_complete()` and `isinstance(tx, PartialTransaction)`,
which is that technically you can have a PSBT that is already complete
but was not yet converted to a standard bitcoin tx.
- no more passing around "invoice" in GUIs, invoice "paid" detection is now handled by wallet logic
- a tx can now pay for multiple invoices
- an invoice can now be paid by multiple txs (through partial payments)
- new data structure in storage: prevouts_by_scripthash
- type: scripthash -> set of (outpoint, value)
- also, storage upgrade to build this for existing wallets
- persisted states are saved
- state transitions are checked
- transient states are stored in channel.peer_state
- new channel states: 'PREOPENING', 'FUNDED' and 'REDEEMED'
- upgrade storage to version 21
jsondb takes a copy of the whole self.receiving_addresses
good for avoiding race conditions but horrible for performance...
this significantly speeds up at least
- synchronize_sequence, and
- is_beyond_limit (used by Qt AddressList)
previously load_transactions() had to be called before upgrade();
now we reverse this order.
to reproduce/illustrate issue, before this commit:
try running convert_version_17 and convert_version_18
(e.g. see testcase test_upgrade_from_client_2_9_3_old_seeded_with_realistic_history)
and then in qt console:
>> wallet.storage.db.get_data_ref('spent_outpoints') == wallet.storage.db.spent_outpoints
False
>> wallet.storage.db.get_data_ref('verified_tx3') == wallet.storage.db.verified_tx
False
