[luffah]

The editor design and functionality seem amazing, but crashs occurs evertime :(

OS : Linux ( Trisquel {a kind of GNU Ubuntu} )
Test case : i openned a css file and edit::::
the program crash on auto-completion

python UliPad.py
begin... 15:01:14
end... 15:01:14
Erreur de segmentation

python UliPad.pyc
begin... 15:05:14
end... 15:05:15
python: Fatal IO error 11 (Ressource temporairement non disponible) on X server :0.0.

@limodou Where is the auto-completion related code in ulipad? I can reproduce this issue in ubuntu 16.04 wxgtk3.0 , I want to try fix it.
Thanks.

[limodou]

in mixins/InputAssistant.py

Maybe a wxpython bug?

[zhangchunlin]

It seems that it is a multi-thread issue : https://groups.google.com/forum/#!topic/wxpython-users/6rKyY_ICUSc
Maybe some code need to change to use callafter?
But it is too hard to debug this kind of problem.

[limodou]

Yes I think so.

I found that the crash still happen in ubuntu16.04 wxgtk2.8
I install wxgtk2.8 using method of this article: http://askubuntu.com/questions/789302/install-python-wxgtk2-8-on-ubuntu-16-04

But still crash, so it might not because of wxpython version.

[zhangchunlin]

There are 2 kinds of errors, one is

begin... 21:54:15
end... 21:54:16

get_calltip main
     attributes: [] firstword: main

     result: source [name=main,type=function,span=[4, 7],info=main(),docstring=] []
     ready to output: source [name=main,type=function,spa

the other:

[zhangchunlin]

But I try wxpython 2.8 demo in ubuntu 16.04, didn't find any crash.

[limodou]

我不知道是不是和按键事件的处理有关。因为我为了实现延迟处理，以避免按得快时每次都激活自动补全，所以对按键事件进行了捕获和模拟。可能会对linux不兼容。

[zhangchunlin]

@limodou 这部分代码在哪里?说不定有规避的方法哈.

[limodou]

主体在mixinx中的Editor.py中：

    def clone_key_event(self, event):
        if wx.version().split('.')[:2] > ['2', '8']:
            evt = MyKeyEvent()
            evt.altDown = event.altDown
            evt.controlDown = event.controlDown
            evt.KeyCode = event.KeyCode
            evt.metaDown = event.metaDown
            if wx.Platform == '__WXMSW__':
                evt.RawKeyCode = event.RawKeyCode
                evt.RawKeyFlags = event.RawKeyFlags
            #evt.m_scanCode = event.m_scanCode
            evt.shiftDown = event.shiftDown
            evt.X = event.X
            evt.Y = event.Y
        else:
            evt = wx.KeyEvent()
            evt.m_altDown = event.m_altDown
            evt.m_controlDown = event.m_controlDown
            evt.m_keyCode = event.m_keyCode
            evt.m_metaDown = event.m_metaDown
            if wx.Platform == '__WXMSW__':
                evt.m_rawCode = event.m_rawCode
                evt.m_rawFlags = event.m_rawFlags
            #evt.m_scanCode = event.m_scanCode
            evt.m_shiftDown = event.m_shiftDown
            evt.m_x = event.m_x
            evt.m_y = event.m_y
            evt.SetEventType(event.GetEventType())
            evt.SetId(event.GetId())
        return evt

我通过克隆按键事件，然后延迟处理。不知道这块是不是有问题。

[zhangchunlin]

recommend ninja-ide ( http://ninja-ide.org/ ), but just use the stable version (now 2.3.x), the beta version 3.x is not stable.

[N46AN]

Maybe we can add another option to disable automatic code completion. Instead, a shortcut key has to be pressed to trigger completion.

[zhangchunlin]

Yes, @N46AN @limodou
After I remove the "def clone_key_event(self, event):" function body, ulipad do not crash any more
