Ok, I've committed the change as you suggested to CVS for all the PCall functions. Test Lua code: f = wx.wxFrame(wx.NULL, -1, "Hello") t = wx.wxLuaGridTableBase() t.GetNumberRows = function(self) return 1*x -- this is an error end g = wx.wxGrid(f, -1) g:SetTable(t) f:Show(true) I get this error (as expected): Running lua script 'untitled.lua' : Tue Dec 2 00:02:32 2008 Error: Lua: Error while running chunk [string "untitled.lua"]:7: attempt to perform arithmetic on global 'x' (a nil value) stack traceback: [string "untitled.lua"]:7: in function <[string "untitled.lua"]:6> [C]: in function 'SetTable' [string "untitled.lua"]:11: in main chunk Please let me know if it doesn't crash for you after this change. Also, what platform and compiler do you use.

John Labenski — 2008-12-02T01:08:19

The code above is basically identical to how it is now, what do you mean it goes into no man's land? To be sure; I agree that there is a currently a problem in that we really should check the return value of the pcall() and if there is an error, not try to get values from the stack and show an error message, but I do not want wxLua to crash. Take for example: modules/wxbind/src/wxadv_wxladv.cpp and the function wxLuaGridTableBase::GetNumberRows() ... m_wxlState.LuaPCall(1, 1); numrows = (int)m_wxlState.GetNumberType(-1); m_wxlState.lua_SetTop(nOldTop); If there is an error in the Lua code run by LuaPCall(), an error message string is left on the stack. The next line (see modues/wxlua/src/wxlstate.cpp); wxLuaState::GetNumberType(-1) calls wxlua_getnumbertype() which fails since the item at the top of the stack isn't a a number, wxlua_argerror() is called which calls wxlua_argerrormsg() which finally calls wxlua_error().

Re: completion in the editor (A word to the wise)

You are thinking of the AutoCompSetSeparator not the AutoCompSetTypeSeparator :) which is used to get an image of some kind to be display beside the string. This go sour when they try to retrieve this none existent image.

This code goes into no mans land. The original code reports the error on the console if the console is active and in a message box if it is not active. I think it is the right solution.

Re: completion in the editor (A word to the wise)

John Labenski — 2008-12-01T04:43:33

I'm not sure I understand. Could you explain how to duplicate the crash with the editor.wx.lua program? I would have thought that if you have a ? in your string that the auto completion list would simply break your string into two separate items in the list. Which isn't want you want, but it shouldn't crash.

Re: Loading modules

John Labenski — 2008-12-01T04:30:34

I have thought about making this possible, but it will not currently work. It is unfortunate that the memory usage is so high, however on a modern computer, it's a trivial amount. The issues with separating the wxLua module is that the wxWidgets libs would have to separated out and you'd end up with more than a dozen separate libs.

Re: could someone make the following changes inwxadv_wxladv.cpp

John Labenski — 2008-12-01T04:26:20

I've been thinking about this. Currently; the pcall suppresses any errors, which is bad, but any subsequent calls to get values from the stack would error and that's where you crash I assume. If I catch the error in pcall as above and don't get values from the stack, but make the C++ function call with some sort of reasonable values it hides the problem. I think this code would be more appropriate, however I think it will still crash for you. Could you test this? if (m_wxlState.LuaPCall(1, 1) != 0) m_wxlState.wxlua_Error("Error in function... blah blah, get error string from stack..."); Regards, John ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Change all the call to LuaPCall to setup the result only when the code succeed ex: m_wxlState.LuaPCall(1, 1); to if (m_wxlState.LuaPCall(1, 1) == 0) the are a number of those lines This cause the program to crash particularly if the console is active.

Please change all m_wxlState.LuaPCall(.*) to if (m_wxlState.LuaPCall(.*) == 0) checking for the status is necessary when a console is active. At other times we probably just lucked out. If the console is active and Error is invoked within the callback then the program crash.

completion in the editor (A word to the wise)

arpin — 2008-11-26T18:18:10

If you do not use the TypeSeparator in completion then add the following line of code to your editor initialization. editor:AutoCompSetTypeSeparator(0) this will set the separator to null which is not likely to be a valid character in your string. If you do not do that and you have a ? in your completion string then you will simply crash in UserListShow.

Re: problem with call back

John Labenski — 2008-11-25T19:24:01

It is interesting that it only happens in the debugger. In the past I've only had problems that for some reason won't occur in the debugger and those are particularly difficult to diagnose. Lets just chalk it up to a bad interaction of the long jump with the debugger. However, I do appreciate the reports of things not working as expected.

Re: problem with call back

John Labenski — 2008-11-25T15:51:57

This is the same problem as your last report. You're in a virtual C++ function handing the call to your Lua function and apparently the long jump out of the C++ function corrupts the stack (I assume). I will try to debug this, but I don't have very high hopes since I imagine that I would have to override the error() function, save the values, set a flag, and then call it later when it is safe, but I'd still have to return "something" from the C++ function just to get out of it... I'd use a print statement and handle the error as gracefully as possible so the program can continue.

Re: wxlua does not properly report an error (crashinstead)

John Labenski — 2008-11-25T15:43:07

This is always going to be a problem I imagine. wxLua merely wraps wxWidgets and doesn't rewrite it. Therefore, when you return nil, but a string is expected, a lua_error is thrown (actually a long jump) and the C++ stack is corrupted since we're in a virtual C++ function handling your Lua function. A good fix for this would take a lot of work and make updating to new versions of wxWidgets very painful since they would have to be done by hand. You do get an error stating that a string was expected right? The best I can say is take heed of the error message and return a string!

Re: Balloon popup

John Labenski — 2008-11-25T15:25:53

You're right, I forgot to add wxPopupWindow. Try wxMiniFrame, which might even be better since you'll get a close button too. I'd use a wxTimer for the delay, but be sure to connect to the EVT_CLOSE_WINDOW event so that if the user closes it you can ignore the timer event.
