Provide a way to prevent GPUI from creating AccessKit adapters, and enable this in Zed. This will allow us to test AccessKit support in Zed without rolling it out more broadly, while we gain confidence in the implementation in GPUI. I've also added a log statement ## Motivation (i.e. a mini post-mortem about the #56065 panics) Merging #56065 caused some nasty panics in nightly. This was caused by a bug in the logic for selecting a focus node for a `TreeUpdate`. AccessKit panics when an invalid `TreeUpdate` is provided. My assumption was that, since Zed uses no a11y APIs, and also that essentially 0 zed users would have AT apps running, that merging this PR would have no effect on the behaviour of Zed itself. However, two issues combined to cause the panics: - It seems like many people (everyone?) on mac gets the activation callback called by accesskit_macos. A quick search suggests this might be due to password managers searching for password fields, but not sure how true that is. - The bug in question related to *forgetting to check* whether a node used a11y APIs, so we *were* pushing non-empty `TreeUpdate`s As a (probably temporary) defensive measure, I added a function to try to detect the bad cases and fix them. But it would be lovely if this could live in AccessKit itself, since it would mean we wouldn't have to do the check twice (once in GPUI, once in AccessKit). This would also help prevent drift when updating accesskit versions if new invariants are added. We also cannot protect against this with `catch_unwind`, since we use `panic=abort`. So our only option unfortunately is to temporarily disable AccessKit until we know our implementation is stable. Release Notes: - N/A or Added/Fixed/Improved ... |
