(https://github.com/bitcoin/bitcoin/pull/32084#discussion_r2019761404)
That limit likely caused us to miss the typo (splitting between related words), it's why I have also reordered it minimally to be structured by meaning instead.

I don't think it is, but like you am unsure about what the guarantees of the protocol are here.

I kind of reverse engineered this looking at miniupnpc and netlink sources, along with an `strace` of `ip route show`, which is where the repeated `recv` calls jumped out to me as a difference between our code and other tools.

This approach simply relies on receiving an `NLMSG_DONE` to signal the end of the response and break. This should handle both single and multi-part messages. Here's a snip

💬 maflcko commented on pull request "fuzz: Make partially_downloaded_block more deterministic":
(https://github.com/bitcoin/bitcoin/pull/32158#issuecomment-2763285550)
I've run `cargo run --manifest-path ./contrib/devtools/deterministic-fuzz-coverage/Cargo.toml -- $PWD/bld-cmake/ $PWD/../b-c-qa-assets/fuzz_corpora/ partially_downloaded_block 128` for about 300 times and it passed. So hopefully this is good enough for now. (In theory the scheduler thread may still be woken spuriously, even if there is no work, but the only solution to that would be to disable it completely for all fuzz targets that don't need it.)

> I guess the advantage of the on-the-fly heap would be that you may never have to calculate the ordering for some chunks in the middle of the mempool

This is possible even with the existing index-based structure, by allowing chunk feerates to be indeterminate, and index them by a known lower and upper bound. That would necessitate two precomputed indexes (one for block building, sorted by the upper bound; one for eviction, sorted by the lower bound), and relinearizing whatever cluster was f

📝 hebasto opened a pull request: "depends: Switch from multilib to platform-specific toolchains"
(https://github.com/bitcoin/bitcoin/pull/32162)
Using the multilib GCC toolchain, as currently documented in [`depends/README.md`](https://github.com/bitcoin/bitcoin/blob/4c1906a500cacab385b09e780b54271b0addaf4b/depends/README.md), has several issues, such as:

1. The [`g++-multilib`](https://packages.ubuntu.com/noble/g++-multilib) package conflicts with platform-specific cross-compiler packages. This means it is not possible to cross compile for `i686` and other platforms using the same set of installed packages.

Thanks!

The receive flow [here](https://www.infradead.org/~tgr/libnl/doc/core.html#core_recv) seems to indicate:
- Process packet
- If `NLM_F_MULTI` is set and the packet is not `NLMSG_DONE`, repeat

What i'm mostly worried about is that the current code will hang if `NLMSG_DONE` never comes, which seems to be the case for non-multi responses, which have one data packet.

But it may be that the `NETLINK_ROUTE` response to `NLM_F_DUMP` is always multi-packet. That empirically seems to be

> Wouldn't it be better to set this to `static_cast<uint32_t>(nHeight +99 );`?
That would make the transaction invalid and unable to be included in a block until the `nHeight + 99` block is not a condition on when it can be spent, but when it is valid (therefore it can be mined).

Renamed the `flags` parameter to `mode`, matching the analogous change in the BIP draft.
Rebased to the latest master.

Still trying to locally reproduce the unit test failures.

Sorry, that the builder *doesn't* outlive the graph. I was testing to see what happens when it *does* outlive it, and it's not crashing currently.
