From 4f39eb031af8690eb86eb781e43b10141dd47da9 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Wed, 9 Mar 2022 16:01:42 +0000 Subject: [PATCH] bundle: unbundle promisor packs In order to have a valid pack-file after unbundling a bundle that has the 'filter' capability, we need to generate a .promisor file. The bundle does not promise _where_ the objects can be found, but we can expect that these bundles will be unbundled in repositories with appropriate promisor remotes that can find those missing objects. Use the 'git index-pack --promisor=' option to create this .promisor file. Add "from-bundle" as the message to help anyone diagnose issues with these promisor packs.
