Bitcoin-core 0.15.1 gettransaction showing wrong fee for some transactions #12364
Description
What makes me wonder, this happens just for some transactions
Take a look at this transaction:
20179d0d2fba68b2ca82ab8cc5faa39ced73324af6b90b6505cca2c3d65102a6
As you can see inputs/outputs fee is: 0.001 BTC
In bitcoin-core gettransaction
bitcoin-cli gettransaction "20179d0d2fba68b2ca82ab8cc5faa39ced73324af6b90b6505cca2c3d65102a6" true
Returns this result:
Array

[amount] => -105.21509845
[fee] => 105.11519845
[confirmations] => 78
[blockhash] => 0000000000004caf7faef44b3cd20424b04e8044a8d323064e1fca6864b96cb9

But with this transaction everything is fine:
20179d0d2fba68b2ca82ab8cc5faa39ced73324af6b90b6505cca2c3d65102a6
bitcoin-cli gettransaction "20179d0d2fba68b2ca82ab8cc5faa39ced73324af6b90b6505cca2c3d65102a6" true
Result:
Array
(
[amount] => -1.049
[fee] => -0.001
[confirmations] => 136
[blockhash] => 0000000000000fd2e83cc1a8145b055a1a33ea996f7a93578197a48848201a5b

)
)
to get the fee of that type of transactions we could do:
105.21509845 (amount) - 105.11519845(fee) = 0.001
But why bitcoin core doesn't do it and why it's only for some transactions?
