debuginfod support

tip

This page assumes familiarity with what debuginfos are. First read the debuginfos docs page if you are not already familiar with debuginfos.

Unfortunately, packages distributed by various Linux distros strip away debuginfos to minimize the size of the binaries.

Thankfully, there are publicly accessible servers, distributing debuginfos for various Linux package managers and distributions.

debuginfod is an HTTP file server that serves debuginfos to clients based on the Build IDs of the binaries. You can find out the Build ID of a binary using the file command on Linux.

Here is an example to find out the Build ID of a zsh binary:

$ file /bin/zsh

/bin/zsh: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=24fcd0179bb3aa797de6a570c2359e528f7638c0, for GNU/Linux 3.2.0, stripped

Parca integrates with debuginfod to query for upstream debuginfod files and then stores them for potential later use. The default debuginfod server used by Parca is: https://debuginfod.elfutils.org

To use a different set of debuginfod servers to attempt to retrieve debuginfos from use the --debuginfod-upstream-servers flag.
