Saving buildGitInfo lambda into a member variable by dougqh · Pull Request #10615 · DataDog/dd-trace-java

What Does This Do

Saving buildGitInfo lambda into a member variable

Motivation

Unfortunately, profiles show the lambda from this::buildGitInfo was a hot allocation point. That would suggest that escape analysis wasn't able to kick in here.

So I introduced a member variable to hold the variable to avoid repeatedly allocating

Interesting, I wonder if it's related to the large use of nested lambdas inside buildGitInfo?

EDIT: I'm wondering if it might be because buildGitInfo is not stateless, so the JVM doesn't cache the reference (https://stackoverflow.com/a/23991339)

Interesting, I wonder if it's related to the large use of nested lambdas inside buildGitInfo?

EDIT: I'm wondering if it might be because buildGitInfo is not stateless, so the JVM doesn't cache the reference (https://stackoverflow.com/a/23991339)

Yes, very likely. We could also solve this by making DDCache have a routine that takes an extra context argument.
Then we could do DDCache.computeIfAbsent(this, key, (thiz, key) -> thiz.buiildContextIInfo(key))
