[Bug 1887144] Re: autopkgtest failures on ppc64el with nodejs 12.18.2

2020-08-07 Thread Olivier Tilloy
Reported as an upstream Node.js bug:
https://github.com/nodejs/node/issues/34666

** Description changed:

  Since nodejs 12.18.1 entered groovy-proposed, autopkgtests that rely on
  node-sha.js to compute SHA-1 hashes started failing reliably on ppc64el.
  This affects the following packages:
  
    - node-sha.js
    - node-crypto-browserify
    - node-create-hash
  
  Other architectures do not appear to be affected, and it's only the
  SHA-1 hashes that are incorrect, other hashing algorithm are not
  affected.
  
  For reference, I'm attaching the full log for the last failed run of
  node-create-hash on ppc64el (see
  https://autopkgtest.ubuntu.com/packages/n/node-create-
  hash/groovy/ppc64el).
  
- Upstream bug report: https://github.com/crypto-
- browserify/sha.js/issues/66
+ Upstream (sha.js) bug report: 
https://github.com/crypto-browserify/sha.js/issues/66
+ Upstream (Node.js) bug report: https://github.com/nodejs/node/issues/34666

Unfortunately, that was a red herring. I rebuilt nodejs for ppc64el with
that commit reverted, but it didn't help.

Just a wild guess that will need testing: https://chromium-
review.googlesource.com/c/v8/v8/+/1649711 might be related, would
reverting it help?

(note that I'm not suggesting the above as a workaround, we need to dig
deeper and understand where this incorrect optimization comes from)

To further prove the point, adding `eval('')` to the body of ft()
ensures that the function is not optimized by V8, and the tests reliably
pass.
