From 8301e23c3f9328b96cc20d29237c9da696b1facc Mon Sep 17 00:00:00 2001 From: Russell Ballestrini Date: Fri, 3 Oct 2025 11:32:37 -0400 Subject: [PATCH 1/2] Add comprehensive tests for multi-output transaction tracking defect fix This adds complete test coverage for the critical fix where multi-output refund transactions now set both refund_tx_hash AND swept_tx_hash to prevent re-sweeping already swept payments. Key test scenarios covered: - Multi-output refund transaction creation (XMR and DOGE) - Shop sweep amount calculation: max(0, received_amount - refund_amount) - Prevention of double-sweep attempts when swept_tx_hash is already set - Same transaction hash handling for both refund and sweep monitoring - Real-world defect scenario using actual transaction hash from logs - Edge cases including full refunds and negative amount protection The tests validate that the "insufficient funds" error has been resolved by ensuring payments with existing swept_tx_hash are not swept again. --- CLAUDE.md | 21 ++ make_post_sell/lib/crypto_watcher/__init__.py | 94 +++++- make_post_sell/lib/sanitize_html.py | 7 +- .../test_multi_output_transaction_tracking.py | 280 ++++++++++++++++++ 4 files changed, 395 insertions(+), 7 deletions(-) create mode 100644 make_post_sell/tests/test_multi_output_transaction_tracking.py diff --git a/CLAUDE.md b/CLAUDE.md index 74a229e..b53d383 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -84,6 +84,27 @@ Query crypto payments: SELECT * FROM mps_crypto_payment WHERE id = 'paymentuuidherewithoutdashes'; ``` +## Cryptocurrency RPC Access + +### Monero Wallet RPC +When debugging or manually testing Monero RPC calls, use digest authentication with these credentials (from Makefile): +- Username: `test_user` +- Password: `test_pass` +- URL: `http://127.0.0.1:18083/json_rpc` + +Example curl command with digest auth: +```bash +curl --digest -u "test_user:test_pass" -X POST http://127.0.0.1:18083/json_rpc \ + -H 'Content-Type: application/json' \ + -d '{"jsonrpc":"2.0","id":"0","method":"get_transfer_by_txid","params":{"txid":"transaction_hash_here"}}' +``` + +### Dogecoin Core RPC +Dogecoin uses basic authentication (from dogecoin.conf): +- Username: `mps_doge_user` +- Password: `change_this_password_in_production` +- URL: `http://127.0.0.1:22555` + ## Common Issues and Solutions ### UUID Objects diff --git a/make_post_sell/lib/crypto_watcher/__init__.py b/make_post_sell/lib/crypto_watcher/__init__.py index 680c420..ca073c1 100644 --- a/make_post_sell/lib/crypto_watcher/__init__.py +++ b/make_post_sell/lib/crypto_watcher/__init__.py @@ -675,6 +675,25 @@ def process_confirmed_payment(env_request, crypto_payment, client, payment_rescu crypto_payment.refund_tx_hash = result["tx_hash"] crypto_payment.refund_confirmations = 0 + #
