Summary: Broken implementation of XIMStringConversionCallback in
libX11.
Product: xorg
Version: 6.8.2
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Lib/Xlib
AssignedTo: xorg-bugzilla-noise at freedesktop.org
ReportedBy: suzhe at tsinghua.org.cn

Hi,
Recently I'm investigating how to implement surrounding text support in SCIM
XIM server. I found that XIMStringConversionCallback API in XIM can be used to
do such job. But laterly I found that the implementation of this API in libX11
is broken.
You may read the source file lib/X11/imCallbk.c line 285-365
_XimStrConversionCallback function. The implementation of this function is
completely broken, for example, it doesn't handle null pointer exceptions,
wide_char and multibyte string issue and doesn't do memory free, etc.
I'll try to fix the implementation, but I'm not a X11 expert, so I'll very
apperciate if you can fix it or give me some hint on how to fix it.
ps. surrounding text support very important for some CTL languages.
