我有一个相当复杂的GUI,通过在
linux上运行的
python的tkinter编写,其中一个组件(具有经常更新的Text小部件)导致GUI不经常崩溃(每天一次).
通过X11和Gnome 2.28.2在Mac OSX上运行的guis显示为具有相同的行为.我的python版本是3.3,tk / tcl版本是8.5.我得到的错误是：
X Error of Failed request: BadIDChoice (invalid resource ID chosen for this connection) Major opcode of Failed request: 148 (RENDER) Minor opcode of Failed request: 4 (RenderCreatePicture) Resource id in Failed request: 0x116517f Serial number of Failed request: 15106831 Current serial number in output stream: 15106872
一个strace看起来像：
11:03:29.632041 recvfrom(13,0x3bae1d4,4096,0) = -1 EAGAIN (Resource temporarily unavailable)
11:03:29.632059 recvfrom(13,0) = -1 EAGAIN (Resource temporarily unavailable)

11:03:29.637387 close(35) = 0
11:03:29.637820 write(2,"X Error of Failed request: BadI"...,91) = 91
...
我的GUI是单线程的(并使用after()调用来监视I / O的套接字).
有谁知道什么可能是错的？有没有更好的调试,我可以做出来找出X错误部分的含义？
解决方法
使用以下日志偶尔崩溃(每天一次)……
X Error of Failed request: BadIDChoice (invalid resource ID chosen for this connection) Major opcode of Failed request: 148 (RENDER) Minor opcode of Failed request: 4 (RenderCreatePicture)
…似乎是xcb中已知问题的标志性签名,如下面的线程中的mentioned：
07001
它的补丁可以在here获得.
根据git历史记录,这个xcb bug应该在libX11-1.1.99.2及更高版本(〜8年前)中修复.
