From 7cce9074a728fb32501054577963d8ae31d007be Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Thu, 22 Dec 2022 15:14:10 +0000 Subject: [PATCH] bundle-uri client: add boolean transfer.bundleURI setting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The yet-to-be introduced client support for bundle-uri will always fall back on a full clone, but we'd still like to be able to ignore a server's bundle-uri advertisement entirely. The new transfer.bundleURI config option defaults to 'false', but a user can set it to 'true' to enable checking for bundle URIs from the origin Git server using protocol v2.
