From: Jeffrey Czyz Date: Tue, 6 Aug 2024 21:21:32 +0000 (-0500) Subject: Test verification with experimental offer TLVs X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=6a708e2d9fa6fbdb592e1e9e856430182e1927dd;p=rust-lightning Test verification with experimental offer TLVs Offer metadata is generated from the offer TLVs and should included those in the experimental range. When verifying invoice request and invoice messages, these TLVs must be included. Similarly, OfferId construction should included these TLVs as well. Modify the BOLT12 verification tests to cover these TLVs. --- diff --git a/lightning/src/offers/invoice.rs b/lightning/src/offers/invoice.rs index c8be0e377..fcc723474 100644 --- a/lightning/src/offers/invoice.rs +++ b/lightning/src/offers/invoice.rs @@ -1716,7 +1716,9 @@ mod tests { message_paths: None, }, SignatureTlvStreamRef { signature: Some(&invoice.signature()) }, - ExperimentalOfferTlvStreamRef {}, + ExperimentalOfferTlvStreamRef { + experimental_foo: None, + }, ), ); @@ -1810,7 +1812,9 @@ mod tests { message_paths: None, }, SignatureTlvStreamRef { signature: Some(&invoice.signature()) }, - ExperimentalOfferTlvStreamRef {}, + ExperimentalOfferTlvStreamRef { + experimental_foo: None, + }, ), ); @@ -1904,6 +1908,7 @@ mod tests { let offer = OfferBuilder::deriving_signing_pubkey(node_id, &expanded_key, nonce, &secp_ctx) .amount_msats(1000) .path(blinded_path) + .experimental_foo(42) .build().unwrap(); let invoice_request = offer.request_invoice(vec![1; 32], payer_pubkey()).unwrap() .build().unwrap() @@ -1925,6 +1930,7 @@ mod tests { let offer = OfferBuilder::deriving_signing_pubkey(node_id, &expanded_key, nonce, &secp_ctx) .amount_msats(1000) // Omit the path so that node_id is used for the signing pubkey instead of deriving it + .experimental_foo(42) .build().unwrap(); let invoice_request = offer.request_invoice(vec![1; 32], payer_pubkey()).unwrap() .build().unwrap() @@ -1946,6 +1952,7 @@ mod tests { let secp_ctx = Secp256k1::new(); let refund = RefundBuilder::new(vec![1; 32], payer_pubkey(), 1000).unwrap() + .experimental_foo(42) .build().unwrap(); if let Err(e) = refund diff --git a/lightning/src/offers/invoice_request.rs b/lightning/src/offers/invoice_request.rs index 231c582d5..b80d82ce3 100644 --- a/lightning/src/offers/invoice_request.rs +++ b/lightning/src/offers/invoice_request.rs @@ -1434,7 +1434,9 @@ mod tests { paths: None, }, SignatureTlvStreamRef { signature: Some(&invoice_request.signature()) }, - ExperimentalOfferTlvStreamRef {}, + ExperimentalOfferTlvStreamRef { + experimental_foo: None, + }, ), ); @@ -1482,6 +1484,7 @@ mod tests { let offer = OfferBuilder::new(recipient_pubkey()) .amount_msats(1000) + .experimental_foo(42) .build().unwrap(); let invoice_request = offer .request_invoice_deriving_metadata(signing_pubkey, &expanded_key, nonce, payment_id) @@ -1565,6 +1568,7 @@ mod tests { let offer = OfferBuilder::new(recipient_pubkey()) .amount_msats(1000) + .experimental_foo(42) .build().unwrap(); let invoice_request = offer .request_invoice_deriving_signing_pubkey(&expanded_key, nonce, &secp_ctx, payment_id) diff --git a/lightning/src/offers/offer.rs b/lightning/src/offers/offer.rs index 1c7eac616..3f7e049dc 100644 --- a/lightning/src/offers/offer.rs +++ b/lightning/src/offers/offer.rs @@ -225,6 +225,8 @@ macro_rules!
