Welcome to GitGitGadgetHi @abraithwaite, and welcome to GitGitGadget, the GitHub App to send patch series to the Git mailing list from GitHub Pull Requests. Please make sure that either:
You can CC potential reviewers by adding a footer to the PR description with the following syntax: NOTE: DO NOT copy/paste your CC list from a previous GGG PR's description, Also, it is a good idea to review the commit messages one last time, as the Git project expects them in a quite specific form:
It is in general a good idea to await the automated test ("Checks") in this Pull Request before contributing the patches, e.g. to avoid trivial issues such as unportable code. Contributing the patchesBefore you can contribute the patches, your GitHub username needs to be added to the list of permitted users. Any already-permitted user can do that, by adding a comment to your PR of the form Both the person who commented An alternative is the channel Once on the list of permitted usernames, you can contribute the patches to the Git mailing list by adding a PR comment If you want to see what email(s) would be sent for a After you submit, GitGitGadget will respond with another comment that contains the link to the cover letter mail in the Git mailing list archive. Please make sure to monitor the discussion in that thread and to address comments and suggestions (while the comments and suggestions will be mirrored into the PR by GitGitGadget, you will still want to reply via mail). If you do not want to subscribe to the Git mailing list just to be able to respond to a mail, you can download the mbox from the Git mailing list archive (click the curl -g --user "<EMailAddress>:<Password>" \
--url "imaps://imap.gmail.com/INBOX" -T /path/to/raw.txtTo iterate on your change, i.e. send a revised patch or patch series, you will first want to (force-)push to the same branch. You probably also want to modify your Pull Request description (or title). It is a good idea to summarize the revision by adding something like this to the cover letter (read: by editing the first comment on the PR, i.e. the PR description): To send a new iteration, just add another PR comment with the contents: Need help?New contributors who want advice are encouraged to join git-mentoring@googlegroups.com, where volunteers who regularly contribute to Git are willing to answer newbie questions, give advice, or otherwise provide mentoring to interested contributors. You must join in order to post or view messages, but anyone can join. You may also be able to find help in real time in the developer IRC channel, |

External tools like git-lfs and git-fat use the filter clean/smudge mechanism to manage large binary objects, but this requires pointer files, a separate storage backend, and careful coordination. Git's partial clone infrastructure provides a more native approach: large blobs can be excluded at the protocol level during fetch and lazily retrieved on demand. However, enabling this requires passing `--filter=blob:limit=<size>` on every clone, which is not discoverable and cannot be set as a global default. Add a new `fetch.blobSizeLimit` configuration option that enables size-based partial clone behavior globally. When set, both `git clone` and `git fetch` automatically apply a `blob:limit=<size>` filter. Blobs larger than the threshold that are not needed for the current worktree are excluded from the transfer and lazily fetched on demand when needed (e.g., during checkout, diff, or merge). This makes it easy to work with repositories that have accumulated large binary files in their history, without downloading all of them upfront. The precedence order is: 1. Explicit `--filter=` on the command line (highest) 2. Existing `remote.<name>.partialclonefilter` 3. `fetch.blobSizeLimit` (new, lowest) Once a clone or fetch applies this setting, the remote is registered as a promisor remote with the corresponding filter spec, so subsequent fetches inherit it automatically. If the server does not support object filtering, the setting is silently ignored. Signed-off-by: Alan Braithwaite <alan@braithwaite.dev>
