From 23c887f97eeb08ee2a318b28878edb488428f98d Mon Sep 17 00:00:00 2001 From: Gusted Date: Sun, 17 Dec 2023 16:39:58 +0100 Subject: [PATCH] [GITEA] Avoid `WHERE IN` for comment migration query - Rewrite `UpdateCommentsMigrationsByType` to not use `WHERE IN` as that's a performance diaster for MariaDB, it now use batching to query the the relevant comment IDs via JOINs (which is not possible in a UPDATE query for SQLite) and then update them in a seperate query. - Add unit test. - Resolves https://codeberg.org/forgejo/forgejo/issues/1856 (cherry picked from commit 8098ca9d2e391b17e5e3da5cfa5af042221bfe36) Conflicts: models/issues/comment.go https://codeberg.org/forgejo/forgejo/pulls/2075 (cherry picked from commit ca65deba1cc183ce1643ee6a1f698c5ecb2ac571) (cherry picked from commit 0e1e09e77dd1bc82b1eae02147fddca1d9954469) (cherry picked from commit 19013ba5eac756044e6307abee6fb5d6709c855d) --- models/issues/comment_test.go | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) diff --git a/models/issues/comment_test.go b/models/issues/comment_test.go index c5bbfdedc2..e08bd7fbf5 100644 --- a/models/issues/comment_test.go +++ b/models/issues/comment_test.go @@ -12,6 +12,7 @@ import ( repo_model "code.gitea.io/gitea/models/repo" "code.gitea.io/gitea/models/unittest" user_model "code.gitea.io/gitea/models/user" + "code.gitea.io/gitea/modules/structs" "github.com/stretchr/testify/assert" ) @@ -97,3 +98,29 @@ func TestMigrate_InsertIssueComments(t *testing.T) { unittest.CheckConsistencyFor(t, &issues_model.Issue{}) } + +func TestUpdateCommentsMigrationsByType(t *testing.T) { + assert.NoError(t, unittest.PrepareTestDatabase()) + + issue := unittest.AssertExistsAndLoadBean(t, &issues_model.Issue{ID: 1}) + repo := unittest.AssertExistsAndLoadBean(t, &repo_model.Repository{ID: issue.RepoID}) + comment := unittest.AssertExistsAndLoadBean(t, &issues_model.Comment{ID: 1, IssueID: issue.ID}) + + // Set repository to migrated from Gitea. + repo.OriginalServiceType = structs.GiteaService + repo_model.UpdateRepositoryCols(db.DefaultContext, repo, "original_service_type") + + // Set comment to have an original author. + comment.OriginalAuthor = "Example User" + comment.OriginalAuthorID = 1 + comment.PosterID = 0 + _, err := db.GetEngine(db.DefaultContext).ID(comment.ID).Cols("original_author", "original_author_id", "poster_id").Update(comment) + assert.NoError(t, err) + + assert.NoError(t, issues_model.UpdateCommentsMigrationsByType(db.DefaultContext, structs.GiteaService, "1", 513)) + + comment = unittest.AssertExistsAndLoadBean(t, &issues_model.Comment{ID: 1, IssueID: issue.ID}) + assert.Empty(t, comment.OriginalAuthor) + assert.Empty(t, comment.OriginalAuthorID) + assert.EqualValues(t, 513, comment.PosterID) +}
