|
|
||
| When we made changes to rely on libuv realpath it was a semver-major change which introduced new errors and removed `cache` argument. This broke some ecosystem modules, notably `glob`. Also broke some path-related stuff in Windows. | ||
|
|
||
| We chose libuv realpath because it’s much more performant. | ||
|
|
||
| Options: | ||
| - Revert to old behavior. Would lose perf gains. Would be semver-major change. | ||
| - Add new method e.g. `realpath2` which uses old behavior. | ||
| - **Keep new behavior and add logic in Node to handle new/unexpected errors.** | ||
|
|
||
| @jasnell - We did a semver-major revert for the symlink issue.<br /> | ||
| @trevnorris - No need to revert, just handle the errors.<br /> | ||
| @jasnell - Do we really know what the errors are so we can be sure we’re handling all of them?<br /> | ||
| @trevnorris - we can compare to old impl.<br /> | ||
| @jasnell - Add an option to the options object to suppress errors, turn on by default.<br /> | ||
|
|
||
| **@trevnorris will work on option 3.** | ||
|
|
||
| Post-mortem: https://github.com/nodejs/CTC/issues/9 | ||
| - Postpone till Rod is present. | ||
| - @jasnell - We didn’t follow typical deprecation path for `cache` parameter change. | ||
|
|
||
|
|
||
| ### ES6 modules | ||
|
|
||
| - https://github.com/bmeck/UnambiguousJavaScriptGrammar | ||
|
|
||
| - Any code with `import` or `export` is a module, otherwise a script. | ||
| - `modules.root` aspect removed, so “fat packages” (i.e. incl. both ES6 and CJS) are not addressed. Recommendation is to use one or the other and transpile as needed. Or discuss `modules.root` separately. | ||
| - Users can explicitly specify module goal in package.json. This way even if dev removes all `import/export` from their code it’s still treated as a module. | ||
| - TC39 could provide a “recommendation” or endorsement supporting this. They may suggest a spec extension. | ||
|
|
||
| @bradleymeck - still need modules.root for fat packages. | ||
|
|
||
| What about bytecode caching? Provide hooks to allow user to handle as desired. That means caching is in userland. Might split this into separate proposal. | ||
|
|
||
| @trevnorris analyzed perf hit of double parsing and found max 25% perf hit. | ||
|
|
||
| In-band detection (from the code itself) is preferable to out-of-band detections (e.g. package.json, file extension). | ||
|
|
||
| CJS and ES6 semantic interoperability: Bradley is working on this, working with WHATWG Loader spec and V8. | ||
| - `this` value | ||
| - live bindings for getters (get updated values) (?) | ||
| - immutability - hooks for APM providers to wrap original functions. To be handled by WHATWG Loader spec. | ||
|
|
||
| **@jdalton - How do we finalize consensus on this?** | ||
| - **PR to change [node-eps:/002-es6-modules.md](https://github.com/nodejs/node-eps/blob/master/002-es6-modules.md)** | ||
