vm: fix produceCachedData
#5343
Conversation
Fix segmentation faults when compiling the same code with `produceCachedData` option. V8 ignores the option when the code is in its compilation cache and does not return cached data. Added `cachedDataProduced` property to `v8.Script` to denote whether the cached data is produced successfully.

One nit, otherwise looking good. Going to give a try before landing, though. |
|
LGTM |
|
@jasnell this is not in v4.x, please remove the tag. |
|
@indutny the watch tag is for us to audit a commit to be backported |
|
@thealphanerd I'm just saying that it should be don't land on v4.x |
|
Ahhh... got it 😄 |
|
Landed in d5c04c3, thank you! |

Changed tags myself. |
|
Argh, concurrency! :) |
|
@indutny would you be able to add a small sentence about why this commit is not an LTS candidate? |
|
Because |
|
@thealphanerd we may want to reconsider this a bit later, though. I just don't want to make a commitment to supporting this on a LTS level yet. If things will work out - there are no blockers in backporting all of code cache changes to v4.x and releasing them in next minor. |
