From c9854bee98e3cfd6e50a797d4da9585929a37856 Mon Sep 17 00:00:00 2001 From: Lunny Xiao Date: Tue, 12 Mar 2024 15:23:44 +0800 Subject: [PATCH] Do some performance optimize for issues list and view issue/pull (gitea#29515) This PR do some performance optimzations. - [x] Add `index` for the column `comment_id` of `Attachment` table to accelerate query from the database. - [x] Remove unnecessary database queries when viewing issues. Before some conditions which id = 0 will be sent to the database - [x] Remove duplicated load posters - [x] Batch loading attachements, isread of comments on viewing issue --------- Co-authored-by: Zettat123 Conflicts: models/issues/comment_code.go: function was renamed in Forgejo models/migrations/migrations.go: migration already ported --- models/issues/comment.go | 8 +-- models/issues/comment_code.go | 4 +- models/issues/comment_list.go | 78 +++++++++++++++++++++------- models/issues/issue_list.go | 25 +++++++-- models/repo/attachment.go | 2 +- routers/api/v1/repo/issue_comment.go | 4 -- routers/web/repo/issue.go | 39 ++++++-------- routers/web/repo/pull_review.go | 8 ++- 8 files changed, 106 insertions(+), 62 deletions(-) diff --git a/models/issues/comment.go b/models/issues/comment.go index 984fb9c9fc..1e962b52f7 100644 --- a/models/issues/comment.go +++ b/models/issues/comment.go @@ -673,7 +673,8 @@ func (c *Comment) LoadTime(ctx context.Context) error { return err } -func (c *Comment) loadReactions(ctx context.Context, repo *repo_model.Repository) (err error) { +// LoadReactions loads comment reactions +func (c *Comment) LoadReactions(ctx context.Context, repo *repo_model.Repository) (err error) { if c.Reactions != nil { return nil } @@ -691,11 +692,6 @@ func (c *Comment) loadReactions(ctx context.Context, repo *repo_model.Repository return nil } -// LoadReactions loads comment reactions -func (c *Comment) LoadReactions(ctx context.Context, repo *repo_model.Repository) error { -
