Discourse 核心中一项将显著加快热链接图片获取速度的更改刚刚被合并：

FEATURE: Pull hotlinked images immediately after posting

committed 01:28PM - 23 May 22 UTC

Previously, with the default `editing_grace_period`, hotlinked images were pulle…d 5 minutes after a post is created. This delay was added to reduce the chance of automated edits clashing with user edits. This commit refactors things so that we can pull hotlinked images immediately. URLs are immediately updated in the post's `cooked` HTML. The post's raw markdown is updated later, after the `editing_grace_period`. This involves a number of behind-the-scenes changes including: - Schedule Jobs::PullHotlinkedImages immediately after Jobs::ProcessPost. Move scheduling to after the `update_column` call to avoid race conditions - Move raw changes into a separate job, which is delayed until after the ninja-edit window - Move disable_if_low_on_disk_space logic into the `pull_hotlinked_images` job - Move raw-parsing/replacing logic into `InlineUpload` so it can be easily be shared between `UpdateHotlinkedRaw` and `PullUserProfileHotlinkedImages`

对于使用此主题组件的用户来说，这意味着热链接图片的缩略图将几乎立即生成，而不是像以前那样延迟 10 分钟
