Simon H	a60995abef	fix: allow async `{@const}` in more places (#16643) ... Implemented by reusing the `async_body` function inside `Fragment.js`. Also removes the ability to reference a `{@const ...}` of an implicit child inside a boundary pending/failed snippet: - existing duplication of consts can have unintended side effects, e.g. async consts would unexpectedly called multiple times - what if a const is the reason for the failure of a boundary, but is then referenced in the failed snippet? - what if an async const is referenced in a pending snippet? deadlock - inconsistent with how it behaves for components where this already does not work Implemented via the experimental flag so the behavior change only applies there as this is a breaking change strictly speaking. Also added a compiler error for this. closes #16462	2 weeks ago

Simon H	98d14ece66	fix: rework binding ownership validation (#15678) ... * remove old validation * fix: rework binding ownership validation Previously we were doing stack-based retrieval of the owner, which while catching more cases was costly (performance-wise) and prone to errors (as shown by many issues over the months). This drastically simplifies the ownership validation - we now only do simple static analysis to check which props are mutated and wrap them with runtime checks to see if a binding was established. Besides making the implementation simpler and more performant, this also follows an insight we had over the months: Most people don't really know what to do with this warning when it's shown beyond very simple cases. Either it's not actionable because they don't really know how to fix it or they question if they should at all (in some cases rightfully so). Now that the warning is only shown in simple and easy-to-reason-about cases, it has a much better signal-to-noise-ratio and will hopefully guide people in the right direction early on (learn from the obvious cases to not write spaghetti code in more complex cases). closes #15532 closes #15210 closes #14893 closes #13607 closes #13139 closes #11861 * remove some now obsolete tests * fix * better warnings now that we have more info * fix * hoist * we only care about mutation, not reassignment * tidy * handle prop aliases * mutation validation is only tangentially linked to context requirement * no need for two vars, one will do * update warning, include mutation location * tweak --------- Co-authored-by: Rich Harris <rich.harris@vercel.com>	5 months ago
