Ludovic,

I've merged all your PRs, including the two "touchy" ones. I've seen no issues but a couple of bug fixes included.

I still need to test these with idf5 (i.e. the new idf5 branch state), idf3 builds & runs fine.

The IDF version switches of course don't add readability, as expected. But if they can be kept that small, I don't see any problems.

I would opt for excluding the IDF 4 branches, to aid in keeping these as small as possible. I don't see any advantage in IDF 4 over 5 -- do you?

Regards,
Michael

Hi Mark,

You're certainly right : WolfSSH writes here https://github.com/wolfSSL/wolfssh : "wolfSSH is dependent on wolfCrypt, found as a part of wolfSSL".

So it seems we need to bundle it still, and it's a good thing we managed to have it more or less compile with ESP-IDF 5+ (a few bugs are still being ironed out - especially the OPENSSL compatibility layer, which may not be used if mongoose does use mbedTLS instead).

Regarding the integration, I tried (my best :-)) to have it build on both ESP-IDF 3, ESP-IDF 5 (and also ESP-IDF 4 with a small patch to the ESP-IDF build system itself). Of course I need help for testing / reproducing the builds and I'm grateful to those of you sparing some time to do exactly that.

I have another round of PRs waiting for some peer-review : https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pulls?q=is%3Aopen+is%3Apr+author%3Allange+draft%3Afalse

-> @List, do not hesitate to have a look - especially for the ones that are a little bit touchy:

https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/831 is trying to guess whether the multiple switch case falls-through are wanted, or not. It impacts the code of multiple people, so it would be interesting if those people could have a look at it.

https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/835 is also a big piece and would benefit from a peer-review.

Thanks in advance !

Regards,

Michael, Ludovic,

Actually one of the next things I wanted to try/determine is why you want/need to use wolfSSL instead of mbedTLS, which we've been using since wolfSSL failed so miserably about the Let's encrypt root certificate transition. Is there an issue with mbedTLS in idf5?

My memory was that wolfssh required wolfssl? But I may be mistaken.

We still need to decide on the integration way. Mark's suggestion was doing the idf5 transition in a separate branch that will later become the new "master". That would keep the idf3 build clean from any regressions, but need merging any work done on that branch into the idf5 branch, which may become a lot of additional work, depending on the time needed to finish the transition.

If this can cleanly be applied to the existing work, to allow building under either v3 or v5 IDF, that would be ideal. IMHO, the separate branch would only be required if the changes were very extensive and breaking to v3.

Regards, Mark.
