Step by step debugging fails after pcall #24

Open ignacio opened 10 years ago

ignacio commented 10 years ago

Given the following snippet:

local string = require "string"

pcall(error, "some error")

print("hello world")
print("bar")

If I set a breakpoint on line 1, and then go step by step with F10 (Step Over), it works until I try to step over the line with pcall. At that point it just runs until the end.

However, if I step with F11 (Step Into), I can step on each line with no problem.

Tested this with Decoda 1.16 and 1.17 (build 1035 beta 1), it behaves the same in both.

Notice that this is true only if an error is raised inside pcall.

My condition: In void DebugFrontend::EventThreadProc(); In eventId == EventId_Break After pcall stackFrame is set ok, however, the next stackFrame get a look wrong value from m_pipe. End

if (m_stackFrames[i].scriptIndex != -1) { //TODO //assert(m_stackFrames[i].scriptIndex < m_scripts.size()); if (m_stackFrames[i].scriptIndex >= m_scripts.size()) { m_stackFrames[i].scriptIndex = -1; } } works temporarily ;)
