From 4a48370d91354c2857ade10a177c8827b5866e4c Mon Sep 17 00:00:00 2001 From: Giteabot Date: Fri, 3 Nov 2023 16:29:30 +0800 Subject: [PATCH] Fix DownloadFunc when migrating releases (#27887) (#27889) Backport #27887 by @Zettat123 We should not use `asset.ID` in DownloadFunc because DownloadFunc is a closure. https://github.com/go-gitea/gitea/blob/1bf5527eac6b947010c8faf408f6747de2a2384f/services/migrations/gitea_downloader.go#L284-L295 A similar bug when migrating from GitHub has been fixed in #14703. This PR fixes the bug when migrating from Gitea and GitLab.
