ubuntu 11.10 上删除Empathy的聊天记录

  下载LOFTER 我的照片书  |
之前一直不知道怎么把这个记录给删掉,烦死了。可不能留下私密信息在这里阿,就下载了Empathy源码下来看一下检查一下。好像Empathy的文档没有有,我没仔细看,反正网上的文档搜到的文档说的位置是错的,可能因为Empathy 更新了吧。

根 据代码,Empathy使用的是 Telepathy 框架,所以这个 聊天记录使用的也是“Telepathy Logger”这个模块来作的。Telepathy Logger的文档在 http://telepathy.freedesktop.org/wiki/Logger ,提到

--------------
It stores its logs to

 ${XDG_DATA_HOME}/share/TpLogger

which usually expands to at

 ${HOME}/.local/share/TpLogger/
--------------------

我到我自己的 home 目录 /home/widebright/.local/share/TpLogger/logs
下面一看,果然聊天记录都在这里,yahoo messager 和spark的记录都保存在 帐号名字/联系人名字/聊天日期.log 这样的子目录的文件里面,明文 的xml格式的。
我把把这下面的东西都清空了。然后在Empathy 里面设置了不保存密码。这下终于放心了。

看 代码的时候,发现这个Empathy的聊天记录界面,还是用webkit来做的。很有意思,有的树型节点的操作、显示那些都是写在html的 javascript里面,然后在gtk里面调用的,很有意思。如果想在gtk窗口上面嵌入一个浏览器窗口作显示的,也可以参考这个代码吧。我之前就不知 道这个webkit还能这样用的。
