Code Review Triage
From Audacity Wiki
|This page is associated with the code review initiative. The intention is to classify different issues found in code review, with discussion on the talk page.
We're currently using this triage list for general points that are not specific to one piece of code or algorithm.
- There is a lot of use of 'new/delete' in working with sample buffers and envelope point buffers. These are typically allocated and deallocated with every repaint of the screen. This is inefficient, causes memory fragmentation and is 'unchecked'. The success/failure of the new/delete is unchecked (minor). The indexing into the buffers is unchecked (major). We need a "SmartBuffer" that can as an option allocate on-stack to rectify this. It could also alert us if very large buffer sizes were requested e.g. with zoomed out views of large projects.
May Do Now
- The vim indent setting footers at the end of every page are (arguably) just an annoyance. Needs checking on audacity-devel that there is a consensus that they are not such a good idea after all.
- Tag handling is verbose code, rather like how dialog building code was before ShuttleGui. A similar technique could make this code much more readable.
