CommentView Plugin for IDAPro7.0

自从ida升级7.0 之后,hexrays做了很多的改动,以前的插件基本都废掉了。于是想要找个插件就变得很困难,最近分析一个文件需要获取所有的注释,但是那个针对低版本开发的commentview已经无力回天了。虽然晚上有开源的代码,但是实际修改起来比较蛋疼,不知道是不是ida的问题,编译的插件获取的地址基本都是错误的。还是按照以前的使用区段枚举,和inf信息获取的方法获取到的地址都错了,着tm就很尴尬了,测试代码如下:

for (int i = 0; i < get_segm_qty(); i++) {
        segment_t *seg = getnseg(i);
        qstring segname;
        get_segm_name( &segname,seg, 1024);
        msg("segname: %s, start_ea= %08x, end_ea= %08x , size=%08x \n", segname.c_str(), seg->start_ea, seg->end_ea, seg->size());
    }
msg("Database Info: start_ea= %08x, min_ea= %08x, max_ea= %08x, omin_ea= %08x, omax_ea= %08x \n", inf.start_ea, inf.min_ea, inf.max_ea, inf.omin_ea, inf.omax_ea);
    msg("lowoff= %08x, highoff= %08x, main= %08x \n", inf.lowoff, inf.highoff, inf.main);

实际获取到的数据如下,测试环境为OSX + IDA 7.0,如果谁看到了这篇文章还获取到了正确的地址麻烦通知我一声(感谢匿名用户的评论反馈:那个基址问题应该是IDA的BUG,在新的IDA 7.0.171130 (SP1)里已经修正了的,如果是正版的话就升级一下吧。)。

segname: .text, start_ea= 10001000, end_ea= 00000001 , size=effff001 
segname: .idata, start_ea= 10005000, end_ea= 00000006 , size=efffb006 
segname: .rdata, start_ea= 1000513c, end_ea= 00000003 , size=efffaec7 
segname: .data, start_ea= 10006000, end_ea= 00000005 , size=efffa005 
Database Info: start_ea= 10007000, min_ea= ff000000, max_ea= 00000000, omin_ea= 0006000f, omax_ea= 06400007 
lowoff= 00500046, highoff= 00000301, main= 10007000 

获取到的end_ea都是错的。

于是只好改变思路,使用idapython来做,由于以前没怎么用python写过插件,所以到处找代码折腾了这么个东西。好歹是满足了需求了,如果有更多的需求自己修改代码吧。如果做了修改麻烦提交下改动,谢谢。

代码如下:

  1. 那个基址问题应该是IDA的BUG,在新的IDA 7.0.171130 (SP1)里已经修正了的,如果是正版的话就升级一下吧。

  2. 你好,请问
    错误:(‘invalid syntax’, (”, 98, 42, ‘ return self.Show(self.modal) >= 0\n’))
    是怎么回事?

    1. 你可以看下idc.GetCommentEx这个api有没有其它的参数,或者换新版的ida 使用插件的方式尝试一下。
