In partial clone checkouts (e.g. --filter=blob:none or blob:limit=10k), DownloadPatchSet previously invoked `git fetch <remote> <ref>` without explicit filter overrides. Consequently, git fetch applied the configured partial clone filter from the remote and omitted the blobs for the incoming change. When repo download subsequently checks out, cherry-picks, or merges the downloaded commit, Git discovers that the required blobs are missing locally and triggers on-demand unadvertised object fetches to the promisor remote (POST /git-upload-pack with `want <blob_sha>`). On large repositories, server-side reachability validation for unadvertised objects can result in expensive graph traversals, proxy/gateway timeouts (such as HTTP 502 or connection drops), and client fetch failures: fatal: expected 'packfile' fatal: could not fetch <sha> from promisor remote Pass --no-filter (when Git >= 2.17.0) and --no-tags when fetching patch sets in DownloadPatchSet. Because the change ref is an advertised ref tip, fetching with --no-filter allows the server to generate a complete packfile containing all required blobs upfront without requiring unadvertised object reachability checks. All blobs are present in the local object database prior to checkout or cherry-pick, completely preventing on-demand promisor queries.

repo
Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

Contact
Please use the repo-discuss mailing list or issue tracker for questions.
You can file a new bug report under the "repo" component.
Please do not e-mail individual developers for support. They do not have the bandwidth for it, and often times questions have already been asked on repo-discuss or bugs posted to the issue tracker. So please search those sites first.
Install
Many distros include repo, so you might be able to install from there.
# Debian/Ubuntu.
$ sudo apt-get install repo
# Gentoo.
$ sudo emerge dev-vcs/repo
You can install it manually as well as it's a single script.
$ mkdir -p ~/.bin
$ PATH="${HOME}/.bin:${PATH}"
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
$ chmod a+rx ~/.bin/repo
Shell Completion
Repo includes completion scripts for Bash and Zsh.
Bash
To enable completion in Bash, source completion.bash in your ~/.bashrc:
source /path/to/git-repo/completion.bash
Zsh
To enable completion in Zsh, you can either:
-
Copy or symlink
completion.zshto a file named_repoin a directory in your$fpath:mkdir -p ~/.zsh/completion # You can copy the file: cp /path/to/git-repo/completion.zsh ~/.zsh/completion/_repo # Or symlink it: ln -s /path/to/git-repo/completion.zsh ~/.zsh/completion/_repoThen add that directory to your
fpathin~/.zshrcbeforecompinit:fpath=(~/.zsh/completion $fpath) autoload -Uz compinit compinit -
Or source the file directly and call
compdefin your~/.zshrc:source /path/to/git-repo/completion.zsh compdef _repo repo
