src: generate debug symbols bundle on OS X by zcbenz · Pull Request #227 · nodejs/node

This will generate *.dSYM symbols on OS X, when we dispatch Node
binaries without debug symbols to users, it can be used to restore
meaningful stack trace from the crash report.

It doesn't affect generated binary.

LGTM but out of curiosity, how big are the debug symbols? It would be somewhat unfortunate if the build starts writing gigabytes of mostly unused symbol data (think out of disk space errors.)

I just updated the patch to only generate symbols for node target, so we won't waste time generating symbols for openssl-cli and others.

This patch now only generates a node.dSYM which is 187M in size, it also adds 10s building time on my machine.

That's a little on the steep side IMO. When you say "can be used to restore meaningful stack trace from the crash report", who/what does that? The binary already has debug symbols.

This is mostly used by developers building products based on io.js, who will distribute binaries that have no debug symbols, I have to admit it doesn't have much value to io.js itself. I'm OK to close this if you think it is not suitable to put it in upstream.

@zcbenz Thanks for your reply, I'll go ahead and close this.
