From cdc9e91750036fc370db65a44618f3139db11ae1 Mon Sep 17 00:00:00 2001 From: FuXiaoHei Date: Mon, 13 Mar 2023 18:23:51 +0800 Subject: [PATCH] add path prefix to ObjectStorage.Iterator (#23332) Support to iterator subdirectory in ObjectStorage for ObjectStorage.Iterator method. It's required for https://github.com/go-gitea/gitea/pull/22738 to make artifact files cleanable. --------- Co-authored-by: Jason Song Co-authored-by: Lunny Xiao --- cmd/dump.go | 6 ++--- modules/doctor/storage.go | 2 +- modules/storage/helper.go | 2 +- modules/storage/helper_test.go | 2 +- modules/storage/local.go | 8 +++++-- modules/storage/local_test.go | 42 ++++++++++++++++++++++++++++++++++ modules/storage/minio.go | 12 +++++++--- modules/storage/storage.go | 4 ++-- tests/test_utils.go | 4 ++-- 9 files changed, 67 insertions(+), 15 deletions(-) diff --git a/cmd/dump.go b/cmd/dump.go index c802849f8e..00d279b991 100644 --- a/cmd/dump.go +++ b/cmd/dump.go @@ -250,7 +250,7 @@ func runDump(ctx *cli.Context) error { if ctx.IsSet("skip-lfs-data") && ctx.Bool("skip-lfs-data") { log.Info("Skip dumping LFS data") -
