Skip Azure DevOps auth in shims when ACTIONS_ID_TOKEN_REQUEST_URL is set

[Copilot]

During Codespaces prebuild (GitHub Actions environment), artifacts-helper shims should not attempt Azure DevOps authentication, as indicated by the presence of ACTIONS_ID_TOKEN_REQUEST_URL.

Changes

• Modified auth-ado.sh to detect GitHub Actions environment and bypass authentication wait
• Updated all shim scripts (dotnet, nuget, npm, yarn, npx, pnpm, pnpx, rush, rush-pnpm) to check for ACTIONS_ID_TOKEN_REQUEST_URL at the beginning and bypass all Azure DevOps-specific operations when set:
  • Skip credential provider installation (for dotnet/nuget shims)
  • Skip setting Azure DevOps environment variables (VSS_NUGET_ACCESSTOKEN, VSS_NUGET_URI_PREFIXES, ARTIFACTS_ACCESSTOKEN)
  • Skip waiting for auth helper
  • Execute the real command directly without any overhead
• Bumped feature version to 3.0.1
• Added documentation in NOTES.md explaining the GitHub Actions / Codespaces Prebuild support

# Each shim now checks at the beginning
if [ -n "${ACTIONS_ID_TOKEN_REQUEST_URL}" ]; then
  source "$(dirname $0)"/resolve-shim.sh
  DOTNET_EXE="$(resolve_shim)"
  "${DOTNET_EXE}" "$@"
  exit $?
fi

Without this fix, package restore operations during prebuild would wait up to 3 minutes for an auth helper that isn't needed in that context, and would unnecessarily install credential providers and set environment variables that could interfere with the GitHub Actions workflow.

Original prompt

On artifacts-helper, A problem with the new artifacts-helper shims is that when someone tries to run dotnet/nuget/npm/yarn during Codespaces creation this process gets in the way. We do NOT want the shims in that scenario and need to execute the real command. We can detect this scenario by the presence of the ACTIONS_ID_TOKEN_REQUEST_URL environment variable. When this variable is set, the shim should not try to obtain an Azure DevOps token and should just proceed to calling the real command

@copilot I think the actual shim scripts also need to be modified because the things they do to set an enviornment variable as part of running the tool will also cause issues

Good catch! Updated all shim scripts to bypass Azure DevOps-specific operations when ACTIONS_ID_TOKEN_REQUEST_URL is set. This now skips:

• Credential provider installation (dotnet/nuget)
• Setting VSS_NUGET_ACCESSTOKEN and VSS_NUGET_URI_PREFIXES
• Setting ARTIFACTS_ACCESSTOKEN
• Waiting for auth helper

The shims now execute the real command directly in GitHub Actions context. Commit: 434e7c2
