A PR that aims at adding a promises-based API to most node core APIs was recently submitted to nodejs/node.
I have expressed my concerns regarding the impact of such a change on post-mortem debugging, and a separate issue was created by @Raynos to further discuss these concerns.
My concerns are more questions that I asked because I felt that the way promises handle errors is incompatible, at least in some ways, with post-mortem debugging. So far my investigations only confirmed these concerns, but I'm not done with them. One part of these investigations is also to find a solution to the problems that I found so far.
The discussion in nodejs/node has been productive so far, but I represent only one post-mortem debugging user/maintainer. I feel it would help if some people from this working group would share their opinion on these concerns with the rest of the group here in this issue, if only to confirm or infirm that they have the same questions/reserves as I do about the impact of nodejs/node#5020 on post-mortem debugging. For instance, if some of you already worked on that problem and did a similar investigation, I would be interested if you could share your results.
In any case, I will share my findings with the group as soon as I have some more time to continue my investigations.
Thank you!
