A plan to support source code indexing on debuginfod.d.n

What is debuginfod?

• Started by Red Hat in 2019.
• It "is a client/server […] that automatically distributes ELF / DWARF / source-code from servers to clients such as debuggers across HTTP".
• The goal is to replace the need for .ddeb files (but it can do more than that).

How does it work?

• There's a debuginfod server (e.g., at https://debuginfod.debian.net) that indexes all available debug information from supported Debian releases.

• Debugger-like tools (e.g., GDB) link against libdebuginfod, which provides the client support.

• When the tool needs a certain debuginfo, it will contact the debuginfod server (specified via the DEBUGINFOD_URLS shell variable) and put a request for the debuginfo's Build-ID.

• If found, the server will then transmit the information over HTTP(S) to the client.

How do I use it?

• You can configure your system by doing:

export DEBUGINFOD_URLS="https://debuginfod.debian.net"

Demo

• Fasten your seat belts, please.
