minidump-debugger

An experimental GUI for rust-minidump based on egui.

NOTE: if building from source on linux, you may need to install the packages egui depends on.

Functionality

At this point the UI is mostly at parity with minidump-stackwalk

• raw minidump inspection (for debugging weird minidumps)
• stackwalking (via cfi, frame pointers, and scanning)
• symbolication (via symbol server, either using native binaries or breakpad .sym)
• processing the minidump's metadata
• trace logs for debugging the stackwalk

Future Functionality?

• (on interactive branch) more responsive live results
• (on interactive branch) log searching/sorting/filtering based on tracing spans ("give me all the info on this thread")
• builtin hexdump viewing (we currently get some from the raw minidump printing, but it's very slow because it doesn't know where we're looking)
• surface more random pieces of information (crash time, endianess, ...)
• (on interactive branch) Linux* stream raw inspection (they have a weird format)
• surface recovered arguments (currently only computed in the x86 backend, kinda jank)
• steal some socc-pair features? (benching, fetching dumps, mocking symbol server, diffing)
• allow the dump to be pointed at a build dir to compute local symbols?

Future Cleanups?

• properly expand table row-heights for line-wrapping items
• better pointer-sized-value formatting (pad 64-bit to 16 chars)
• make more text selectable (bare labels suck for most of what we display)
• don't make the symbol cache checkbox so terribly dangerous (will blindly delete the dir at that path, should just disable the cache)
