Private crates are not supported even with `net.git-fetch-with-cli = true`

[redeexpressos]

.cargo/config.toml:

[net]
git-fetch-with-cli = true

However, when compiling with bitbake, it cannot find the private crates.

What is the workaround for this?

Maybe related to #168

Also, I can login via .netrc inside my bitbake shell, and I can git clone private stuff. But looks like Cargo handles them in a weird way, so my recipe is unable to build because the software has a Cargo.toml that fetches private repositories.
Running out of ideas :(

Looks like adding netrc authentication and:

do_compile:prepend() {
    export CARGO_NET_GIT_FETCH_WITH_CLI=true
}

fixed the issue.

For some reason .cargo/config is not doing what its supposed in this bitbake shell.. I am not sure if someone can reproduce the .cargo/config part. Will wait for feedback

The .cargo/config.toml worked for me, although later I moved to a fixup bbclass which would set the variable in do_compile:prepend as above, because that ensures builds work out of the box without additional setup.

I had another auth related issue though and it only manifested itself when we updated to Debian 10: cargo was not able to fetch anything via https, for instance, it failed fetching a public github repo:

|     Updating git repository `https://github.com/jin-eld/tls.git`
|      Running `git fetch --verbose --force --update-head-ok 'https://github.com/jin-eld/tls.git' '+refs/heads/macos-openssl:refs/remotes/origin/macos-openssl'`
| fatal: unable to access 'https://github.com/jin-eld/tls.git/': error setting certificate file: /usr/local/oe-sdk-hardcoded-buildpath/sysroots/x86_64-pokysdk-linux/etc/ssl/certs/ca-certificates.crt
| error: failed to get `tokio-native-tls` as a dependency of package `client v0.1.0 (/yocto/poky-devel-build/build/work/cortexa53-crypto-poky-linux/client/git/git/lib/client)`

I was quite puzzled, especially by the /usr/local/oe-sdk-hardcoded-buildpath line and the fact, that it worked from the devshell, until I found out that GIT_SSL_CAINFO which is set by /opt/poky/5.0.5/environment-setup-x86_64-pokysdk-linux was not propagated to cargo, despite being listed in BB_ENV_PASSTHROUGH_ADDITIONS.

So my current fixup looks like this:

do_compile:prepend() {
    export CARGO_NET_GIT_FETCH_WITH_CLI=true
    export GIT_SSL_CAINFO="${GIT_SSL_CAINFO}"
}

I think it would probably make sense to add the GIT_SSL_CAINFO export to cargo_bin_do_compile() alongside the other exports, that are already there.
