niftynei	165d039f6c	elements: consolidate fee outputs into a single fee output In the case that you've got more than one fee output already on a psbt, we consolidate them into a single fee output (the first)	4 years ago
niftynei	4c28e7b362	txprepare: elements requires inclusion of an accurate fee output so we add an accurate one	4 years ago
niftynei	24578c7fea	elementsd: use the elements version of a 'witness utxo' Elements requires the witness utxo to include the asset and value info, in order for the signing hash to be constructed correctly Changelog-Fixed: elementsd: PSBTs include correct witness_utxo struct for elements transactions	4 years ago
ZmnSCPxj jxPCSnmZ	5d7178d488	bitcoin/psbt.c: Add psbt_insert_output function.	4 years ago
niftynei	303263d381	psbt: clean up interface for setting metadata on PSBT inputs it's just neater if it's not all wrapped up together, simplifies the interface a smidge	4 years ago
niftynei	0305c0a57e	psbt: if psbt is null, return null for get_bytes	4 years ago
niftynei	10237ccb8e	psbt: handle 'NULL' or empty byte PSBTs Don't crash if the PSBT is null / zero-byte len.	4 years ago

Rusty Russell	a0ede40743	bitcoin: make psbt_append_input more powerful. It can now handle all the metadata as well as the base tx input. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	4 years ago

niftynei	251cde3514	psbt: add helpers for creating + adding input/outputs	4 years ago
Rusty Russell	591e8f9663	psbt: finalize to-remote with option_anchor_outputs. Until it gains miniscript support, wally doesn't know how to finalize P2WSH. This happens with `option_anchor_outputs` for to-remote, which requires a 1 block delay to force use of anchor outputs for CPFP. So we finalize this ourselves.

Rusty Russell	a6a8a40594	psbt: implement psbt_txid. You can't just take the txid of the global tx, if some are p2sh-wrapped. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	4 years ago

Jon Griffiths	95d3d65c62	wally: update to the latest wally version Includes: psbt: Use renamed functions for new wally version psbt: Set the transaction directly to avoid script workarounds psbt: Use low-S grinding when computing signatures tx: Use wally_tx_clone from libwally now that its exported Signed-off-by: Jon Griffiths <jon_p_griffiths@yahoo.com>	4 years ago
Rusty Russell	ffbb409b47	amount: use initializers everywhere. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	4 years ago
niftynei	f5f85b389d	elements,pset: populate elements specific data for PSBTs PSETs have a bit different requirements. The witness_utxo needs the asset tag + values, and these should also be added to the PSET struct separately as well. To do this, we create a new 'init' method for elements inputs, which takes care of the elements specific things.	4 years ago
niftynei	4ecbd5f1a7	psbt: use pset initializer if needed we're moving over to elements!	4 years ago
niftynei	175fcf381a	psbt: have wally_tx serialization methods be legible for gen'd code our code generators expect the serialization name to match the struct type	4 years ago
niftynei	b63abef542	psbt: add method to finalize + extract a psbt will either use a temporary psbt (and not munge the passed in psbt) or will finalize in place -- finalization erases most of the signature metadata from the psbt struct	4 years ago
niftynei	0d1f1bc66e	psbt: add helper method for setting a psbt input's redeemscript	4 years ago
niftynei	c3ae44e296	psbt: don't crash if we can't add a partial sig instead return a boolean indicating the success/failure of a sig set	4 years ago
niftynei	80072b389e	psbt: remove script sig info from inputs before adding them to global PSBT's dont' serialize / unserialize if there's any sig info set on the global transaction	4 years ago
niftynei	5ecacf3dd0	psbt: add type-to-string that prints b64 string Re-uses code from what was the bitcoin_tx_to_psbt_b64	4 years ago
niftynei	58282819a9	psbt: if a transaction has witnesses/scriptSig set, add it to psbt For any transaction that's got 'finalized' signature data for an input, we should add this information to the psbt also	4 years ago
niftynei	052d40ae98	psbt: add method to confirm 'finalized' status of psbt calling `wally_psbt_finalize` doesn't return a status indicator; instead you must call `psbt_is_finalized` to check that it's eligible for 'extraction' -- extraction will fail if the psbt is not in a finalized state.	4 years ago
niftynei	000ef2079c	psbt: helpers for adding a pubkey or signature to a psbt we'll use these for the commitment txs!	4 years ago
niftynei	3c6e3eecee	psbt: add 'wally_psbt_clone' function, to clone a psbt We'll need this for settng the tx correctly, for reasons	4 years ago
niftynei	db8ef922ed	psbt: add to/from byte helpers We'll need these for the database methods we're going to add shortly	4 years ago
niftynei	a04f0fe250	psbt: remove input_amounts from bitcoin tx Instead we will stash them into the PSBT as a utxo/witness record (which includes the amount)	4 years ago
niftynei	cc6eba1d72	psbt: try one big alloc and fail instead of incremental buffer increases was running into buffer overrun errors? something about the iteration method was broken	4 years ago
niftynei	559f88faa1	psbt: add serialize to/from wire for psbts	4 years ago
niftynei	5d0fc176e8	psbt: create new_psbt method Move all psbt creation into single method, new_psbt note that if a psbt is init'd for a transaction that's deserialized with scripts etc already attached, then set_global_tx will fail. instead, we empty all of this out first. if the tx is being re-init'd from a tx source that had a psbt attached (e.g. fromwire_) then the script/witness data will get populated appropriatel from there.	4 years ago
niftynei	2d5c61dfc1	psbt: methods to mutate psbt in place add the missing psbt helpers for adding and removing an input and output	4 years ago
