  "message": "sync: Implement fetchcmd for standard Git layouts\n\nIntroduce support for `repo.fetchcmd` configuration, allowing users to\nspecify a custom command to fetch project data instead of\n`_RemoteFetch`.\n\nWhen `repo.fetchcmd` is specified, `repo` will execute it instead of\n`_RemoteFetch` during the network half of sync. Note that\n`repo.fetchcmd` requires `repo.uselocalgitdirs` to be enabled.\n\nThe command is executed in a subshell with project-context environment\nvariables, including the new `REPO_TREV` (target revision resolved to a\ncommit hash) and `REPO_PROJECT_FETCH_URL`.\n\nAfter execution, `repo` verifies that the target commit is available and\nthat the tracking ref and FETCH_HEAD are correctly updated.\n\nTested with:\n```\n\u003e ~/git-repo/repo init -u https://android-review.googlesource.com/platform/manifest \\\n    --repo-url file:///usr/local/google/home/gavinmak/git-repo \\\n    --groups developers \\\n    --no-repo-verify \\\n    --use-local-gitdirs\n...\n\n\u003e git config --file .repo/manifests.git/config repo.fetchcmd \u0027mkdir -p $REPO_PATH \u0026\u0026 cd $REPO_PATH \u0026\u0026 if [ ! -d .git ]; then git init \u0026\u0026 git remote add aosp $REPO_PROJECT_FETCH_URL; fi \u0026\u0026 git fetch aosp $REPO_TREV \u0026\u0026 git reset --hard $REPO_TREV \u0026\u0026 mkdir -p .git/refs/remotes/aosp \u0026\u0026 echo $REPO_TREV \u003e .git/refs/remotes/aosp/main \u0026\u0026 echo $REPO_TREV \u003e .git/FETCH_HEAD\u0027\n\n\u003e ~/git-repo/repo sync -j32\nwarning: repo is not tracking a remote branch, so it will not receive updates; run `repo init --repo-rev\u003dstable` to fix.\nYou are currently enrolled in Git submodules experiment (go/android-submodules-quickstart).
