This reduces the overhead of the method instrumentation code primarily by reducing the number of method calls. There are also some other small optimisations such as not casting timing values to Floats (there's no particular need for this), using Symbols for method call metric names, and reducing the number of Hash lookups for instrumented methods. The exact impact depends on the code being executed. For example, for a method that's only called once the difference won't be very noticeable. However, for methods that are called many times the difference can be more significant. For example, the loading time of a large commit (nrclark/dummy_project@81ebdea5df2fb42e59257cb3eaad671a5c53ca36) was reduced from around 19 seconds to around 15 seconds using these changes.
Submit new issues created via the WebUI or API to Akismet for spam check on public projects. ## What does this MR do? Submit new issues created via the WebUI by non project members to Akismet for spam check. ## Why was this MR needed? Support for Akismet was added only to the API with !2266. This MR builds on that functionality to also check issues submitted via the WebUI for spam. ## What are the relevant issue numbers? Related to: - #5573 - #5932 - gitlab-com/infrastructure#14 - gitlab-com/support#61 - !2266 cc @stanhu @MrChrisW See merge request !5333
Resolve "HipChat notifications missing colors" _Originally opened at !2322 by @eisnerd._ - - - ## What does this MR do? This MR restores the colors mentioned in #5571 by overriding the color setting with green/red just for build events. ## What are the relevant issue numbers? Closes #5571. See merge request !5498
