Ruby SDK (v1.1.0) is not compatible with Puma

[serggl]

I was trying to switch my app from using hellosign-ruby-sdk to dropbox-sign-ruby and got a crash in Dropbox::Sign::UnclaimedDraftApi#unclaimed_draft_create_embedded when running it with the puma app server:

ETHON: Libcurl initialized
objc[44340]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called.
objc[44340]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.
[44324] - Worker 1 (PID: 44403) booted in 0.0s, phase: 0

My setup is:
Rails - 7.0.4.2
Puma - 6.1.1
Bootsnap - 1.16.0
Spring - not used

Howdy! Can you provide us a bare-bones setup so we can reproduce?

Can you also confirm if the fix shown here helps?

@jtreminio-dropbox I did some little more investigation and found that export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES fixes the issue entirely.

This looks like a bug in typhoeus / ethon.

It would be good to have it documented somewhere
