OS:Centos 6.4
Firefox version: firefox-23.0.source
I downloaded the source code and built it and it worked well.After I
modified the file js/src/jsstr.cpp,when I rum command:./firfox -new-tab
url,firefox starts a new window with one blank page tab.Normally,it should
open one new tab with the url.I just modified one function: template
<AllowGC allowGC>JSStableString *js_NewString(JSContext *cx, jschar *chars,
size_t length);I just want to get the string produced by spidermonkey ,the
page url and then write to a file.
----------------------------------------------------------------------------
----------------------------------------------------
The original code:
template <AllowGC allowGC>
JSStableString *
js_NewString(JSContext *cx, jschar *chars, size_t length)
{
return JSStableString::new_<allowGC>(cx, chars, length);
}
----------------------------------------------------------------------------
----------------------------------------------------
My modified code:
template <AllowGC allowGC>
JSStableString *
js_NewString(JSContext *cx, jschar *chars, size_t length)
{
JSScript * script;
bool token=JS_DescribeScriptedCaller(cx,&script,NULL);
if(token&&length>SHELLCODE_LENGTH)
{
JSObject *hypo_object=JS_GetGlobalForScopeChain(cx);
//get global object whose property location.href contains webpage url
if(hypo_object!=NULL)
{
JS::Value vp;
if(JS_GetProperty(cx,hypo_object,"location",&vp))
//get location property
{
if(vp!=JSVAL_VOID)
{
if(vp.isObject())
{
if(JS_GetProperty(cx,&(vp.toObject()),"href",&vp)) //get href
property
{
if(vp!=JSVAL_VOID)
{
if(vp.isString())
{
JSString* urlString=vp.toString();
const jschar *urlChars=urlString->getCharsZ(cx); //get string
produced by spidermonkey
size_t urlLength=urlString->length();
if(urlChars[urlLength-1]!=47)
return;
//write
webpage url and string to a file
ofstream out;
out.open(FIFO_SERVER,ios::app|ios::binary);
out.write((const char*)(&urlLength),sizeof(urlLength));
out.write((const char*)urlChars,urlLength*2);
out.write((const char*)(&length),sizeof(length));
out.write((const char*)chars,length*2);
out.close();
}
}
}
}
}
}
}
}
return JSStableString::new_<allowGC>(cx, chars, length);
}
I want to use command ./firefox -new-tab url.Unfortunately,modifying
jsstr.cpp made it invalid.Could someone help me?
Help!Thanks!
