…w one via splice. This happens if the channel is *not* announcable yet. Then we hit the assertion in funding_depth_cb that the txid is the same as the current funding.txid. Signed-off-by: Rusty Russell <[email protected]> Changelog-EXPERIMENTAL: fixed crash when we splice a channel which hasn't been announced yet.
I got a NULL deref on `infcopy->remote_funding = *inflight->funding->splice_remote_funding` at once point in testing, so this should prevent that from happening. Signed-off-by: Rusty Russell <[email protected]>
…nge. Signed-off-by: Rusty Russell <[email protected]>
We watch if they are to do with a channel, or have outputs going to us, but otherwise we didn't, so we never updated the blockheight in the db. Signed-off-by: Rusty Russell <[email protected]> Changelog-Fixed: JSON-RPC: `listtransactions` now correctly updates `blockheight` for txs created by `sendpsbt` which have no change outputs.
It now simply renames tal names, so it's harmless to do even if we're not going to do memleak detection. Signed-off-by: Rusty Russell <[email protected]>
…eak coverage for any typed hash table. You can now simply add per-tal-object helpers for memleak, but our older pattern required calling memleak functions explicitly during memleak handling. Hash tables in particular need to be dynamically allocated (we override the allocators using htable_set_allocator and assume this), so it makes sense to have a helper macro that does all three. This eliminates a huge amount of code. Signed-off-by: Rusty Russell <[email protected]>
…ames. Incorporate a time: this covers the restart case as well. And make it time_mono(), which doesn't get overridden when we override normal wall time. Signed-off-by: Rusty Russell <[email protected]>

This was changing all the time when I tried to make autogenerate-rpc-examples.py reproducible. Turns out it was being corrupted (it does suspicious things with pointers); rather than try to diagnose it, I simply rewrote the code to create it only when we need it.

…LN_DEV_ENTROPY_SEED Only in developer mode, ofc. Notes: 1. We have to move the initialization before the lightningd main trace_start, since that uses pseudorand(). 2. To make the results stable, we need to use per-caller values to randbytes(). Otherwise external timing changes the call order. Signed-off-by: Rusty Russell <[email protected]>
This allows us to override it for deterministic results. Signed-off-by: Rusty Russell <[email protected]>

…tion for timeouts. This is immune to things like clock changes, and has the convenient side-effect that it will *not* be overridden when we override time for developer purposes. Signed-off-by: Rusty Russell <[email protected]>

Except for tracing, that sticks with time_now(). Signed-off-by: Rusty Russell <[email protected]>

We have to add a send_and_mine_block() for cases where we want to get a txid and then mine it (for canned blocks, we mine it then figure out which tx it was!). And fix up out-by-one in saving blocks. Signed-off-by: Rusty Russell <[email protected]>

We temporarily add a flake8 exception so it doesn't complain about all the now-unused variables. Signed-off-by: Rusty Russell <[email protected]>

Unless REGENERATE_BLOCKCHAIN is true, in which case we make them. Signed-off-by: Rusty Russell <[email protected]>
This makes our transaction generation (nlocktime) consistent, as well as our htlcs for payment. Signed-off-by: Rusty Russell <[email protected]>
This makes many of our information outputs consistent. Signed-off-by: Rusty Russell <[email protected]>
1. Don't mangle bookkeeper events. 2. Use l3, not l1, for listtransactions: it's more stable. 3. Use l2, not l1, for listpeerchannels and listchannels. 3. Use l2, not l2, for listfunds. (l1 has a lot of variation). Signed-off-by: Rusty Russell <[email protected]>

And hand in CLN_NEXT_VERSION to replace the version string. Signed-off-by: Rusty Russell <[email protected]>
This is `make update-doc-examples-newchain`, which creates the canned blocks (and, since it's the first time, the bitcoind wallet). Signed-off-by: Rusty Russell <[email protected]>

Depends on #8556
Now we do major surgery on autogenerate-rpc-examples.py. Finally we run it to produce the canned blocks and wallet for future runs, and re-enable it in CI.
