Update to esp-idf 5.2.2

[anpin]

Hi, I have just tried your PR and found that idf.py --version still reports to be at 5.1.3

idf.py --version
fatal: not a git repository: '/nix/store/6fhgra3f7pmzljs1gz20ysv8ixq33il1-esp-idf-v5.2.2/.git'
WARNING: Git version unavailable, reading from source
ESP-IDF v5.1.3

btw, there is another similar PR to this one #47

Thanks for pointing this out! I merged the changes into this branch, though I didn't bump in to these problems.

@anpin Does it work for you with the latest changes?

though I didn't bump in to these problems.

I did, that's how I found that PR. You can try to run this to see if your branch is able to build basic examples:

nix-build -E "with import <nixpkgs> {overlays=[(import ./overlay.nix)];}; callPackage ./tests/build-idf-examples.nix {}"

Thank you! With my latest change this build successfully for me at least

One more thing I noticed is that, in that example file, there is still:

  buildsNameList = pkgs.lib.attrsets.cartesianProductOfSets {
    target = [ "esp32" "esp32c3" "esp32s2" "esp32s3" "esp32c6" "esp32h2" ];
    example = [ "get-started/hello_world" ];
  };

With idf 5.2 it looks like we are consolidating the esps2 and esps3 into the esp compiler. So maybe those two extra entries are no longer needed anymore in that test, but I am not sure.

Hi. Is there anything blocking this?

Probably just me having time to review what's been done and merge this - I'll try to do that in the next day or two.

112c9d10b9e171bacf68b91ee63606ab6f9a4529 what is the purpose of the version.txt file? The commit description makes me think its related to the issue that idf.py cannot find the version from git, because the nix store's git repository doesn't retain any tags. But I don't see how the version.txt file would help (and alas, I'm still getting that pesky warning from idf.py)

Honestly I haven't figured out how to get rid of the warning. Something like your earlier commit where you init a git repo inside the store directory, then manually adding the tag there could work, however it doesn't seem like a very stable solution.

On the other hand, maybe the problem is on the esp-idf side. Why should it throw unnecessary stderr warnings when it can't find the version through git tags, when it just falls back to getting the version from cmake, which should probably be the default anyway?

In any case, I've read elsewhere that leaveDotGit should be avoided as the .git folder is not stable. Not sure if that's true but here's the thread: https://discourse.nixos.org/t/keep-git-folder-in-when-fetching-a-git-repo/8590/7

I would also recommend something like this: 0298b4e616b4bbb32a8175fac8c38599e2ea59e3

esp-idf checks that the python executable matches the IDF_PYTHON_ENV_PATH variable, which it won't if you set the env var to the symbolic link instead of the actual executable path. see: https://sourcegraph.com/github.com/espressif/esp-idf/-/blob/tools/idf.py?L110-114

[saippua]

Regarding the leaveDotGit option, I can now confirm that I've experienced some issues when it's set to true. I was trying to build the derivation on a different system but kept getting error: hash mismatch in fixed-output derivation, and the received hash kept changing every time.

Here's the relevant nixpkgs issue. https://github.com/NixOS/nixpkgs/issues/8567

[mirrexagon]

I also have noticed that leaveDotGit makes the output of fetchGit unstable, and yeah, in this case trying to build this branch causes a hash mismatch. @cortex For now, can we undo the leaveDotGit and the version.txt changes? Is that a problem for anyone? In my experience, the warning can just be ignored and everything works well enough.

I've been mostly ignoring trying to deal with the version stuff (#5) since I don't know enough about how the IDF checks versions and it doesn't cause me problems to have the warning.

[cortex]

Great, thanks for removing the git hacking and getting this merged! I'll take a look at the version stuff separately.
