StackTraces

Base.StackTraces.StackFrame — Type
StackFrame

Stack information representing execution context, with the following fields:

  • func::Symbol

    The name of the function containing the execution context.

  • linfo::Union{Method, Core.MethodInstance, Core.CodeInfo, Nothing}

    The Method, MethodInstance, or CodeInfo containing the execution context (if it could be found), or nothing (for example, if the inlining was a result of macro expansion).

  • file::Symbol

    The path to the file containing the execution context.

  • line::Int

    The line number in the file containing the execution context.

  • from_c::Bool

    True if the code is from C.

  • inlined::Bool

    True if the code is from an inlined frame.

  • pointer::UInt64

    Representation of the pointer to the execution context as returned by backtrace.

Base.StackTraces.stacktrace — Function
stacktrace([trace::Vector{Ptr{Cvoid}},] [c_funcs::Bool=false]) -> StackTrace

Return a stack trace in the form of a vector of StackFrames. (By default stacktrace doesn't return C functions, but this can be enabled.) When called without specifying a trace, stacktrace first calls backtrace.

source

The following methods and types in Base.StackTraces are not exported and need to be called e.g. as StackTraces.lookup(ptr).

Base.StackTraces.lookup — Function
lookup(pointer::Ptr{Cvoid}) -> Vector{StackFrame}

Given a pointer to an execution context (usually generated by a call to backtrace), looks up stack frame context information. Returns an array of frame information for all functions inlined at that point, innermost function first.

source
Base.StackTraces.remove_frames! — Function
remove_frames!(stack::StackTrace, m::Module)

Return the StackTrace with all StackFrames from the provided Module removed.

source
remove_frames!(stack::StackTrace, name::Symbol)

Takes a StackTrace (a vector of StackFrames) and a function name (a Symbol) and removes the StackFrame specified by the function name from the StackTrace (also removing all frames above the specified function). Primarily used to remove StackTraces functions from the StackTrace prior to returning it.
