How delve works
UI layer cli tool
Service layer 透過 DAP protocol 實作前後端分離
Symbolic layer line num, types, variable name
Target layer control target process

target layer

gdbserial

symbolic layer

format of debug symbol DWARFv4

service layer

DAP = Debug Adapter Protocol

Debug with delve

$ dlv *.go -- ${parameters}

$ go build -gcflags="all=-N -l" *.go
$ dlv exec ${filename} -- ${parameters}

$ dlv attach ${pid}

Debug with GDB

  • build -gcflags=all=-N -l
  • build -ldflags=compressdwarf=false
  • Load go runtime-gdb.py (src/runtime/runtime-gdb.py)
    • 使 GDB 可以用一些 cmd 去 inspect golang debug info
