From ef4fc302468cc8a9fd8f65c4ebdc6f55138450d1 Mon Sep 17 00:00:00 2001 From: zeripath Date: Mon, 27 Feb 2023 18:46:00 +0000 Subject: [PATCH] Speed up HasUserStopwatch & GetActiveStopwatch (#23051) GetActiveStopwatch & HasUserStopwatch is a hot piece of code that is repeatedly called and on examination of the cpu profile for TestGit it represents 0.44 seconds of CPU time. This PR reduces this time to 80ms. --------- Signed-off-by: Andrew Thornton Co-authored-by: KN4CK3R Co-authored-by: Lunny Xiao Co-authored-by: delvh --- models/issues/stopwatch.go | 34 +++++++++++++++++++---------- models/issues/stopwatch_test.go | 4 ++-- routers/web/repo/issue.go | 15 +++---------- routers/web/repo/issue_stopwatch.go | 14 +----------- 4 files changed, 28 insertions(+), 39 deletions(-) diff --git a/models/issues/stopwatch.go b/models/issues/stopwatch.go index 6bf936c5d..c8cd5ad33 100644 --- a/models/issues/stopwatch.go +++ b/models/issues/stopwatch.go @@ -9,6 +9,7 @@ import ( "time" "code.gitea.io/gitea/models/db" + "code.gitea.io/gitea/models/repo" user_model "code.gitea.io/gitea/models/user" "code.gitea.io/gitea/modules/timeutil" "code.gitea.io/gitea/modules/util" @@ -132,12 +133,26 @@ func StopwatchExists(userID, issueID int64) bool { } // HasUserStopwatch returns true if the user has a stopwatch -func HasUserStopwatch(ctx context.Context, userID int64) (exists bool, sw *Stopwatch, err error) { - sw = new(Stopwatch) +func HasUserStopwatch(ctx context.Context, userID int64) (exists bool, sw *Stopwatch, issue *Issue, err error) { + type stopwatchIssueRepo struct { + Stopwatch `xorm:"extends"` + Issue `xorm:"extends"` + repo.Repository `xorm:"extends"` + } + + swIR := new(stopwatchIssueRepo) exists, err = db.GetEngine(ctx). + Table("stopwatch").
