… Uprobes (#2207) Summary: Add `GoOffsetLocator` that fulfills DwarfReader APIs. Use as shim for Go Uprobes Our current Go uprobe implementation relies on parsing DWARF information. This is memory intensive and is not ideal if end users want to keep the PEM's memory usage low (results in 100-150MB memory spikes). In order to support lower memory uprobes and to support Go binaries without DWARF, we can introduce a shim for the existing DwarfReader API that can read the offsets from a file (via openteletrmy-go-instrumentation generated offsets) or from the existing DWARF information. This PR introduces the `GoOffsetLocator` and tests that it functions properly while leaving the DWARF based tracing in place. The next set of changes will populate the offsets from pixie-io/opentelemetry-go-instrumentation#1 and provide configuration to choose the desired implementation: solely DWARF, solely static offsets or to use them in tandem. Relevant Issues: N/A Type of change: /kind feature Test Plan: Existing Go bpf trace tests should pass --------- Signed-off-by: Dom Del Nano <[email protected]>
