Tezlink/Kernel: Deposit receipt for Tezlink

Arnaud Bihanrequested to merge
arnaud@functori@tezlink_deposit_receipt into master

Linear issue

Closes L2-593

What

Push to the list of applied operation the operation representing the deposit

Why

Currently you can deposit tez to a Tezlink kernel, but you would get 0 feedback on your deposit. It will not appear in the block.

How

We chose to represent a deposit of x tz as a transfer of x tz from address zero to receiver.

For that we change the return of execute_tezlink_deposit to return a TransferContent and a TransferResult.

With those two informations we can build a receipt for a deposit.

Manually testing the MR

You can't test this MR with the tezt_cloud scenario as you need a full rollup setup to do a deposit.

To test the feature in a hackkish way you can put a sleep at the end of test_delayed_deposit_is_included tezt test in etherlink/tezt/tests/tezlink.ml

Then start the test:

dune exec etherlink/tezt/tests/main.exe -- --verbose tezlink deposit > ~/tezt.log&

The tezt tests will do a deposit of 1000 tez for tz1KqTpEZ7Yob7QbPE4Hy4Wo8fHG8LhKxZSx.

You should be able to retrieve the endpoint with a grep on the log:

grep "get balance" ~/tezt.log
[15:35:11.501] [client1] ./octez-client --endpoint http://127.0.0.1:45167/tezlink --base-dir /tmp/tezt-93320/1/client1 get balance for bootstrap1
[15:35:18.301] [client1] ./octez-client --endpoint http://127.0.0.1:45167/tezlink --base-dir /tmp/tezt-93320/1/client1 get balance for bootstrap1

Then you can check the block to find the receipt of the deposit (it should be in block 2)
