NIP-47 got extended to include an optional 'state' field in responses.
Implementing this acutally fixes an issue of Alby Go showing succeeded
payments as failed that appeared recently.
Increase the payment budget before attempting the payment
and decrease again if the payment fails. This prevents a race
where multiple concurrent payments could pass the budget check
before the budget is incremented through any of the other payments.
A lock around the budget is not suitable either as then one long
stuck payment (hold invoice) would render the budget inaccessible for
all other payment attempts.
Stores the currently open (right-click) menu in MyTreeView
and adds a `close_menu()` method so inheritants can cleanly
close the menu again if the context it was opened upon has changed.
This is utilized by `AddressList` and `UTXOList` to close the menu
if a call to `update()` has chenged the address list in some way or
removed a utxo from the list to prevent the user from trying to use
a utxo that doesn't exist anymore.
Fixes#10464
NIP-47 now defines how client/server should communicate their supported
encryption schemes. For backwards compatibility its not strictly
neccessary to implement this but it seems cleaner to explicitly handle
it.
otherwise, when selecting only frozen coins, the set of usable coins is empty, and the menu options
will instead fall back to using ALL coins without informing the user.
If the tx fee of the ctx is already higher than the required target it
is not useful to spend the anchor with a lower fee (the current target),
so instead it is skipped.
"When should we reveal preimages onchain?"
This commit tries to simplify the thinking by making the observation:
- we can reveal preimages (actually in any context) if they are already public
- a preimage is public if any other lightning node knows it besides us
- if we learn the preimage from another LN node, it is public
- if we send update_fulfill_htlc, it becomes public
- if we see a preimage onchain, it is public
- in lnsweep._maybe_reveal_preimage_for_htlc:
- partial mpp check is not relevant if preimage is already public
- let's just always do KeepWatchingTXO, for sanity/safety

Estimate the size of a base tx before stripping its signatures
so the lower bound feerate used to calculate the fee for the rbf
transaction doesn't underestimate the feerate of the base tx.
I noticed CLN is sending our own channel update to us on
reestablishment, we then assume it to be the remote nodes
update and try to verify the signature against their pubkey
which fails and throws `InvalidGossipMsg`.
This adds a check preventing us from trying to save our own
channel updates as remote update.
In the GUIs, on the language-select screen, show e.g.
Czech (100%), Danish (13%), Dutch (54%)
instead of
Czech, Danish, Dutch
- we count the source strings when creating the .pot PO-template file
and add an "X-Electrum-SourceStringCount" header to it, in the push_locale.py script that uploads the .pot file to crowdin.
- later, when we run electrum-locale/update.py to download the translations in .po files, these files will also contain the same header.
- then when the build_locale.sh script compiles those .po files, we can read the header and use it to populate a new "stats.json" file
that we place in electrum/locale/locale/ and bundle in the all release binaries/distributables.
- stats.json also includes the number of translated strings for each lang
- at runtime we simply read stats.json and use the values to calculate the percentages
- a prior implementation did not pre-calc stats.json but did all calculations at runtime (by opening all .mo translations)
- however that was deemed to slow, hence the build-time pre-calc
- runtime calc took 40 ms on my laptop, so I guess it could easily take 10x that on an old phone
- just as we have always been very tolerant of any locale files or even the whole locale/ dir missing, we also tolerate stats.json missing
Assert `WalletDBUpgrader.data` is a regular in-memory dict and not
some StoredDict, so if an exception would happen during a wallet
db upgrade the partial changes don't get commited to disk.
urllib.parse needs to be explicitly imported for e.g. urllib.parse.urlparse to work.
I think this was not erroring only because urllib.parse is imported in other modules.
Catch JavaError when trying to load the java classes of the biometry
module on startup. This can raise if the device is on an old API version
and the loaded java class depends on apis unknown to the os.

Fix exception when clicking on "Donate to server" in offline mode by not
showing the "Donate to server" menu action when no network is set.
Raise CancelledError in `fetch_bitcoin_paper` as
`_fetch_tx_from_network` already shows an according error message so the
second, subsequent error message shown by `on_error` is not useful if
`_fetch_tx_from_network` already failed.

I guess it was a copy-paste error, but still, treat all _() and qsTr() calls as "scary" and as potential attack vectors. Don't blindly call _(): every call needs to be weighed separately.
I tried to reproduce:

This happens because the trustedcoin wallet is loaded outside of
Daemon.load_wallet() so Daemon.update_recently_opened_wallets()
is not getting called and config.RECENTLY:_OPEN_WALLET_FILES is
still None when we try to iterate through it.
As fix i now use load_wallet() instead of manually
instantiating the Wallet
and additionally handle
RECENTLY_OPEN_WALLET_FILES being None in
ElectrumWindow.update_recently_opened_menu().
My pull request https://github.com/spesmilo/electrum/pull/10121
would have sent this exception to the crash reporter so we
might have noticed it earlier. I think we should not just catch
all exceptions in the wizard like on master as it causes us to
repeatedly miss regressions in the wizard that could be sent to
the crash reporter.
