Initial sync failure (Node.js version 14)

[randomlogin]

During initial chain sync I get an error which stops the synchronization. Restarting hsd makes this failing block pass, however the error occurs again, every ~500 blocks.

OS: ubuntu 19.04
node.js: 14.0.0
hsd: 2.1.5

It looks like this is a problem with Node.js v14 that many projects are experiencing

nodejs/node#32463
nodejs/node#32463 (comment)

[Synesso]

Upgrading to node 14.4 fixed this for me.

I think bcoin-org/bcrypto has been recently updated to work around the issue with node. I'll test it out and maybe we can close this issue.

@chjj has fixed this in bcrypto, I was told:

"to fix it i basically just stack allocated everything, so i wouldnt need to use any external buffers"

Will wait for confirmation before closing this issue - @randomlogin feel like giving this another try and make sure you get the latest version of bcrypto installed?

[pinheadmz]

@randomlogin can we close this issue? I'm still using node v12 personally but I think we are cleared for v14 now.

@randomlogin can we close this issue? I'm still using node v12 personally but I think we are cleared for v14 now.

After I faced problems with v14 I moved to the v12. I've tried to test by using v14 after the fix, it was working fine, but it was definitely not an extensive usage.

Closing.
