Wrong transaction order

[awfm9]

Hello dear electrum team.

I somehow managed to get two dependent transactions encoded into the same block. After several confirmations of the transactions & synchronization with several electrum servers, I'm still left with the same issue.

Transaction 1, receiving X coins on address (X coins already).
Transaction 2, sending 2X coins from address.

I have no other bitcoins in my wallet.

In the transaction list, transaction 2 is displayed before transaction 1. This leads to a bug where it will display the overall balance as negative (-X) after transaction 2, followed by transaction 1 which brings it back to zero (0).

I guess you could fix it by either having more exact timestamps (not sure how they work), or by simply making sure than if you have transactions that depend on another transaction, to make them follow it instead of being able to show up in front.

Cheers.

Additionally, while both transactions were still pending, the pruning servers would put one of them into the pruned transactions (behind a LOT of transactions that happened WAY earlier) for some reason, which made the order even more confusing. This was fixed once they got confirmed & timestamped, however.

the first issue is known. dependencies detection needs to be implemented.
I was not aware of the second one.

this is fixed: transactions are now in the correct order (except when they are still pending)
I cannot reproduce the second issue; it might be a thread synchronisation problem.
