  "message": "project: pass --no-filter and --no-tags in DownloadPatchSet\n\nIn partial clone checkouts (e.g. --filter\u003dblob:none or blob:limit\u003d10k),\nDownloadPatchSet previously invoked `git fetch \u003cremote\u003e \u003cref\u003e` without\nexplicit filter overrides. Consequently, git fetch applied the\nconfigured partial clone filter from the remote and omitted the blobs\nfor the incoming change.\n\nWhen repo download subsequently checks out, cherry-picks, or merges the\ndownloaded commit, Git discovers that the required blobs are missing\nlocally and triggers on-demand unadvertised object fetches to the\npromisor remote (POST /git-upload-pack with `want \u003cblob_sha\u003e`). On large\nrepositories, server-side reachability validation for unadvertised\nobjects can result in expensive graph traversals, proxy/gateway timeouts\n(such as HTTP 502 or connection drops), and client fetch failures:\n  fatal: expected \u0027packfile\u0027\n  fatal: could not fetch \u003csha\u003e from promisor remote\n\nPass --no-filter (when Git \u003e\u003d 2.17.0) and --no-tags when fetching patch\nsets in DownloadPatchSet. Because the change ref is an advertised ref\ntip, fetching with --no-filter allows the server to generate a complete\npackfile containing all required blobs upfront without requiring\nunadvertised object reachability checks. All blobs are present in the\nlocal object database prior to checkout or cherry-pick, completely\npreventing on-demand promisor queries.\n\nTAG\u003dagy\nCONV\u003dbdc489e3-b20b-4ef3-b32e-549dbe21fc6c\n\nGoogle-Bug-Id: b/532920848\nTest: pytest tests/test_project.py\nChange-Id: Ic6118e4edeb754f0467e0580fd1d0965a6553153\nReviewed-on: https://gerrit-review.googlesource.com/c/git-repo/+/625621\nReviewed-by: Gavin Mak \u003cgavinmak@google.com\u003e\nTested-by: Sam Saccone \u003csamccone@google.com\u003e\nCommit-Queue: Sam Saccone \u003csamccone@google.com\u003e\n",
