🤔 frankomosh reviewed a pull request: "transaction: Adding script witness to ToString for CTxIn"
(https://github.com/bitcoin/bitcoin/pull/33711#pullrequestreview-3452460486)
I think the goal for this is reasonable, but doesn't it remove witness data from `CTransaction::ToString()` and break existing debug output?

Though I have not done a thorough test, I think that completely removing this might affect debug workflow. Before removing it, `Ctransaction::ToString()` is able to print all inputs, then a separate block with all witnesses, then all outputs. I don’t think this is possible anymore.

I think there might be an inconsistency in formatting here. `scriptWitness.ToString()` is called directly, while `scriptSig` uses `HexStr().substr(0, 24)`. Shouldn't there be some symmetry ?

There is a bit of activity in [Mozilla's fork](https://github.com/MozillaSecurity/cryptofuzz). It's also still present in [OSS-Fuzz](https://github.com/google/oss-fuzz/tree/master/projects/cryptofuzz), but references the non-existent original repository, so probably is not ran anymore.

I am not using GCC, and I am not sure how many devs are using GCC-15. Is there even a ci task using gcc-15? Maybe Alpine 3.23 later this month? I haven't looked at the build system changes, otherwise this seems fine to do.

I don't know anyone who does `-reindex` benchmarks anymore - `-reindex-chainstate` is usually enough, `-reindex` isn't representative of IBD so we have stopped relying on it.

I haven't checked the code yet (am planning on doing that later), but would it be possible to just issue a warning if we're offline and

(https://github.com/bitcoin/bitcoin/issues/33859)
`native_capnp` seems to ignore the CC/CXX settings. This leads to compile failures on distros that come with an older GCC, such as RHEL-based Linux 8, or the latest OpenSuse Leap:

Native compilers are managed by `build_CC` and `build_CXX` variables, no?

thx, i guess some docs about those settings could help. Otherwise, users will have to read the source code.

I included them mainly to visually show % increase, but you’re right that they may be redundant.
(also, I think you have been against adding tests without showing any proof of coverage)
